CALCULATION OF REGISTRATION FEE



Title of each class of securities to be registered	Amount to be registered	Proposed maximum offering price per unit	Proposed maximum aggregate offering price (1)	Amount of registration fee (2)
Class A Common Stock, par value $5.00 per share	7,947,690 (3)	N/A	$268,682,346	$10,560 (4)
Common Stock, par value $1.00 per share	9,483,491 (5)	N/A	N/A (6)	N/A (7)
Total				$10,560

(1)

Estimated solely for purposes of calculating the registration fee required by Section 6(b) of the Securities Act, and calculated pursuant to Rules 457(c) and 457(f) under the Securities Act. The proposed maximum aggregate offering price of the A. O. Smith Corporation (“A. O. Smith”) Class A common stock and A. O. Smith common stock was calculated based upon the market value of shares of Smith Investment Company (“SICO”) common stock (the securities to be cancelled in the merger) in accordance with Rule 457(c) under the Securities Act as follows: the product of (a) $81.00, the average of the high and low prices per share of SICO on January 27, 2009, as quoted on the Pink OTC Markets, Inc., multiplied by (b) 3,317,066, the estimated maximum number of shares of SICO common stock outstanding as of January 27, 2009.

(2)	Calculated by multiplying the estimated aggregate offering price of securities by 0.00003930.

(3)

The maximum number of shares of A. O. Smith Class A common stock estimated to be issuable upon the completion of the merger described herein, calculated as the product of: (a) 3,317,066 shares of SICO common stock and (b) 2.396 shares of A. O. Smith Class A common stock. This number is based on the number of shares of SICO common stock outstanding, as of January 27, 2009, and is calculated in accordance with the formula set forth in the Agreement and Plan of Merger, dated as of December 9, 2008 (the “Merger Agreement”), among A. O. Smith, SICO Acquisition, LLC, SICO and Smith Investment Company LLC.

(4)	Because the amount of registration fee payable is calculated based upon the aggregate offering price which is based upon the proposed maximum aggregate offering price of shares of SICO common stock outstanding as of January 27, 2009, this amount represents the total registration fee payable.

(5)

The maximum number of shares of A. O. Smith common stock estimated to be issuable upon the completion of the merger described herein, calculated as (a) the product of (i) 3,317,066 shares of SICO common stock and (ii) 0.463 shares of A. O. Smith common stock plus (b) 7,947,690 shares of A. O. Smith common stock, which represents the shares issuable upon conversion of all of the A. O. Smith Class A common stock registered hereunder. This number is based on the number of shares of SICO common stock outstanding, as of January 27, 2009 pursuant to the formula set forth in the Merger Agreement.

(6)	The proposed maximum aggregate offering price is calculated based upon the market value of shares of SICO common stock outstanding as of January 27, 2009 and is set forth above. See Footnote 1 for additional information.

(7)	The amount listed above represents the total aggregate registration fee payable. See Footnote 4 for additional information.

The registrant hereby amends this registration statement on such date or dates as may be necessary to delay its effective date until the registrant shall file a further amendment which specifically states that this registration statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933, as amended, or until this registration statement shall become effective on such date as the Securities and Exchange Commission, acting pursuant to said Section 8(a), may determine.

The information in this document is not complete and is subject to change. We may not sell the securities offered by this document until the registration statement filed with the Securities and Exchange Commission is effective. This document is not an offer to sell these securities, and we are not soliciting an offer to buy these securities, in any state where the offer or sale is not permitted.

PRELIMINARY—SUBJECT TO COMPLETION—DATED , 2009

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Stockholders:

The boards of directors of A. O. Smith Corporation, or “A. O. Smith,” and Smith Investment Company, or “SICO,” approved an Agreement and Plan of Merger dated as of December 9, 2008 (the “Merger Agreement”) providing for the merger of SICO with and into SICO Acquisition, LLC, or “MergerCo,” a newly formed subsidiary of A. O. Smith. As of December 31, 2008, SICO owned approximately 97.9% of the outstanding shares of A. O. Smith Class A common stock and 7.1% of the outstanding shares of A. O. Smith common stock, representing a control position in A. O. Smith. A majority of the outstanding shares of SICO common stock is owned by members of the Smith Family, which is the founding family of A. O. Smith.

If the proposed merger is completed, stockholders of SICO will own shares of A. O. Smith directly, rather than through SICO. Stockholders of SICO will be entitled to receive (a) 2.396 shares of A. O. Smith Class A common stock and (b) 0.463 shares of A. O. Smith common stock for each outstanding share of SICO common stock that they hold immediately prior to the effective time of the merger, subject to the treatment of shares required to be placed into escrow, dissenting shares and fractional shares described in this joint proxy statement/prospectus. The calculation of the number of shares of A. O. Smith Class A common stock and A. O. Smith common stock the stockholders of SICO will be entitled to receive assumes that all of the shares of A. O. Smith common stock deposited into escrow are subsequently released to the former SICO stockholders. The consideration that SICO stockholders will be entitled to receive in the merger is more fully described in this joint proxy statement/prospectus under the heading “The Merger Agreement—Consideration to be Received in the Merger” beginning on page 87.

The closing of the merger is conditioned upon, among other things, the affirmative vote of:

•

the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing at least 66-²/₃% of the votes represented by the total number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, in favor of the proposal to adopt the Merger Agreement;

•

the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing a majority of the votes represented by the total number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, in favor of the proposal to adopt the Amended and Restated Certificate of Incorporation of A. O. Smith (the “A. O. Smith Amended Charter”);

•

the holders of A. O. Smith Class A common stock, voting as a separate class, representing a majority of the outstanding shares of A. O. Smith Class A common stock, in favor of the proposal to adopt the A. O. Smith Amended Charter;

•

the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing a majority of the votes cast by such holders at the A. O. Smith special meeting, in favor of the proposal to approve the issuance of A. O. Smith Class A common stock and A. O. Smith common stock to SICO stockholders pursuant to the Merger Agreement (the “Stock Issuance”); and

•

the holders of a majority of the outstanding shares of SICO common stock in favor of the proposal to approve the Merger Agreement.

SICO, which holds shares representing 78.9% of the voting power of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, and 97.1% of the voting power of the total outstanding shares of A. O. Smith Class A common stock, voting as a separate class, has agreed to vote in favor of the merger and the other related proposals to be considered at the special meeting of A. O. Smith stockholders. In addition, holders of 52.7% of the voting power of the total outstanding shares of SICO common stock have agreed to vote in favor of the merger at the special meeting of SICO stockholders. Therefore, stockholders of A. O. Smith and SICO holding voting power sufficient to adopt and approve the merger and the related proposals have agreed to vote in favor of the merger and the related proposals.

The obligations of A. O. Smith and SICO to complete the merger also are subject to the satisfaction or waiver of several other conditions to the merger. More information about A. O. Smith, SICO and the merger is contained in this joint proxy statement/prospectus. We encourage you to read carefully this joint proxy statement/prospectus before voting, including the section entitled “Risk Factors” beginning on page 29.

SICO will hold a special meeting of its stockholders to consider and vote on the approval of the Merger Agreement.

The respective places, dates and times of the special meetings of A. O. Smith and SICO stockholders are as follows:

QUESTIONS AND ANSWERS ABOUT THE MERGER

General Questions and Answers about the Merger and Related Transactions

Below are frequently asked questions and answers regarding the merger.

Q.	Why am I receiving this joint proxy statement/prospectus?

We are delivering this document to you because it is a joint proxy statement used by the A. O. Smith and SICO boards of directors to solicit proxies of A. O. Smith and SICO stockholders in connection with the Merger Agreement. This document also is a prospectus being delivered to SICO stockholders because A. O. Smith is offering shares of its Class A common stock and common stock as consideration to SICO stockholders for their shares of SICO common stock in the merger.

Q.	Why is A. O. Smith proposing this merger?

A.	A. O. Smith believes that substantial benefits to its stockholders can be obtained as a result of the merger. A. O. Smith and its stockholders will benefit from this transaction because its terms provide for:

•

an exchange ratio in the Merger Agreement reflecting a discount of 1.5%, such that the merger will result in a reduction in the number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock by issuing to the SICO stockholders 98.5% of the total number of A. O. Smith shares that SICO holds immediately before the merger;

•

an increase in the public float for A. O. Smith Class A common stock and A. O. Smith common stock, as the A. O. Smith shares currently held by SICO will be distributed more broadly among SICO stockholders; and

•

enhancement of A. O. Smith’s corporate governance structure by:

–

providing that shares of A. O. Smith Class A common stock automatically convert into A. O. Smith common stock, subject to certain exceptions, upon transfer to unaffiliated third parties;

–

providing that all shares of A. O. Smith Class A common stock convert automatically into A. O. Smith common stock once the outstanding shares of A. O. Smith Class A common stock fall below 2,397,976 shares, which is approximately 8% of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock as of the date of the Merger Agreement; and

–

increasing from 25% to 33-¹/3% the percentage of directors that the holders of A. O. Smith common stock have the right to elect to the A. O. Smith board of directors.

For additional information, see “The Merger—A. O. Smith’s Reasons for the Merger; Recommendations of the A. O. Smith Special Committee and the A. O. Smith Board of Directors” beginning on page 62.

Q.	Why is SICO proposing this merger?

A.	SICO believes that substantial benefits to its stockholders can be obtained as a result of the merger.

As of December 31, 2008, SICO owned approximately 97.9% of the outstanding shares of A. O. Smith Class A common stock and 7.1% of the outstanding shares of A. O. Smith common stock, representing a control position in A. O. Smith. A majority of the outstanding shares of SICO common stock is owned by members of the Smith Family, which is the founding family of A. O. Smith.

Historically, SICO’s common stock has traded at a significant discount to the underlying value of its A. O. Smith shares. On February 1, 2008, the last full trading day preceding public announcement of SICO’s proposal for the merger, the aggregate market value of the outstanding shares of SICO common stock traded at a 39% discount to the aggregate value of the A. O. Smith shares held by SICO (assuming a one-for-one

conversion of the A. O. Smith Class A common stock into A. O. Smith common stock). The merger will allow for direct ownership by the SICO stockholders of A. O. Smith shares, which will eliminate the discount to the value of the A. O. Smith shares caused by SICO’s holding company structure and the tax inefficiencies associated therewith, and allow the SICO stockholders to realize the underlying value of the A. O. Smith shares held by SICO. In addition, direct ownership by the SICO stockholders of the A. O. Smith shares will provide enhanced liquidity for SICO stockholders due to the greater public float and trading volumes for the shares of A. O. Smith common stock and its NYSE listing, as compared to the SICO common stock, which has been thinly traded on the Pink OTC Markets, Inc. (the “Pink Sheets”).

For additional information, see “The Merger—SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and the SICO Board of Directors” beginning on page 66.

Q.	What will happen in the proposed transaction?

A.	Under the terms of the Merger Agreement, SICO will merge with and into MergerCo, with MergerCo continuing as the surviving corporation in the merger.

Upon the completion of the merger, which we also refer to as the “effective time” of the merger, MergerCo will be a direct, wholly-owned subsidiary of A. O. Smith. SICO stockholders will receive, pursuant to an exchange ratio set forth in the Merger Agreement, shares of A. O. Smith Class A common stock and shares of A. O. Smith common stock in exchange for their shares of SICO common stock. All other stockholders of A. O. Smith will continue to be stockholders of A. O. Smith following the merger and their shares will not be exchanged.

The closing of the merger is conditioned upon, among other things, the affirmative vote of:

•

the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing at least 66-²/3% of the votes represented by the total number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, in favor of the proposal to adopt the Merger Agreement;

•

the holders of a majority of the outstanding shares of SICO common stock, in favor of the proposal to approve the Merger Agreement.

If adopted, the A. O. Smith Amended Charter provides for:

•

an increase, solely for purposes of completing the merger, in the total number of authorized shares of A. O. Smith Class A common stock that A. O. Smith can issue from 14,000,000 shares to 22,067,252 shares;

•

an increase in the percentage of members of the A. O. Smith board of directors that holders of A. O. Smith common stock, voting as a separate class, elect from 25% to 33-¹/3% of the members of the board of directors (if the 33-¹/3% is not a whole number, then rounding up to the nearest whole number of directors (or four of the ten current directors));

•

the automatic conversion of shares of A. O. Smith Class A common stock into A. O. Smith common stock, subject to certain exceptions, upon transfer to unaffiliated third parties; and

•

the automatic conversion of all shares of A. O. Smith Class A common stock into A. O. Smith common stock once the outstanding shares of A. O. Smith Class A common stock fall below 2,397,976 shares, which is approximately 8% of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock as of the date of the Merger Agreement.

Following the effective time of the merger, A. O. Smith will cancel the shares of A. O. Smith Class A common stock and A. O. Smith common stock currently held by SICO. Under the A. O. Smith Amended Charter, A. O. Smith will be prohibited from reissuing such shares of Class A common stock after they are cancelled. Following the merger and the cancellation of the shares of A. O. Smith Class A common stock held by SICO, the number of shares of A. O. Smith Class A common stock that A. O. Smith is authorized to issue under the A. O. Smith Amended Charter will be the same number as A. O. Smith is currently authorized to issue under the A. O. Smith Existing Charter.

You are urged to read the summary of the proposed changes to the A. O. Smith Existing Charter, as well as the proposed A. O. Smith Amended Charter, contained elsewhere in this joint proxy statement/prospectus.

For additional information regarding the merger, see “The Merger Agreement” beginning on page 87. For additional information regarding the A. O. Smith Amended Charter, see “A. O. Smith Amended Charter” beginning on page 102. For additional information regarding other conditions of the merger, see “The Merger Agreement—Conditions to Obligations to Complete the Merger” beginning on page 96.

Q.	When do A. O. Smith and SICO expect to complete the merger?

A. O. Smith and SICO currently intend to complete the merger promptly following the special meetings of the A. O. Smith and SICO stockholders. However, neither A. O. Smith nor SICO can predict the exact timing of the completion of the merger because the merger is subject to A. O. Smith and SICO satisfying certain conditions. See “The Merger Agreement—Conditions to Obligations to Complete the Merger” beginning on page 96 and “Regulatory Approvals” beginning on page 111.

Q.	Are there risks associated with the merger and the related transactions that I should consider in deciding how to vote?

Yes. There are a number of risks related to the merger and the other transactions contemplated by the Merger Agreement that are discussed in this joint proxy statement/prospectus and in other documents incorporated by reference or referred to in this joint proxy statement/prospectus. Please read with particular care the detailed description of the risks described in “Risk Factors” beginning on page 29 and, with respect to A. O. Smith, in A. O. Smith’s filings with the SEC referred to in “Where You Can Find More Information” beginning on page 138.

Q.	Who will pay the expenses associated with the merger and the related transactions?

A.	SICO will pay for all of its transaction expenses, as well as all reasonable out of pocket fees, costs and expenses in excess of $200,000 incurred by A. O. Smith in connection with the merger and the related transactions.

Q.	What are the United States federal income tax consequences of the merger to the stockholders of A. O. Smith and SICO?

A.	There are no United States federal income tax consequences of the merger to A. O. Smith stockholders with respect to their shares of A. O. Smith Class A common stock or A. O. Smith common stock.

The merger is intended to constitute a tax-free reorganization within the meaning of Section 368(a) of the Code, and the completion of the merger is conditioned upon receiving the IRS Letter Ruling to that effect. Accordingly, a SICO stockholder generally will not recognize gain or loss for United States federal income tax purposes upon the exchange of the stockholder’s shares of SICO common stock for shares of A. O. Smith Class A common stock or A. O. Smith common stock pursuant to the merger, except for any gain or loss recognized in connection with any cash received instead of a fractional share of A. O. Smith Class A common stock or A. O. Smith common stock. Payments, if any, to the SICO stockholders by A. O. Smith for certain tax benefits, refunds and credits of SICO actually realized by A. O. Smith will be taxable when paid to the SICO stockholders.

For more information regarding tax consequences to the SICO stockholders and other tax matters, see “Material United States Federal Income Tax Consequences of the Merger” beginning on page 112. Tax matters can be complicated and the tax consequences of the merger to you will depend on your particular tax situation. You should consult your tax advisor to determine the tax consequences of the merger to you.

Q.	How do the boards of directors of A. O. Smith and SICO recommend that I vote?

The A. O. Smith board of directors, after careful consideration of a variety of factors, including the unanimous recommendation of the A. O. Smith Special Committee, recommends that A. O. Smith stockholders vote “FOR” the proposal to adopt the Merger Agreement, “FOR” the proposal to adopt the A. O. Smith Amended Charter and “FOR” the proposal to approve the Stock Issuance. See “The Merger—A. O. Smith’s Reasons for the Merger; Recommendations of the A. O. Smith Special Committee and the A. O. Smith Board of Directors” beginning on page 62.

The A. O. Smith Special Committee is a committee of three members of A. O. Smith’s board of directors, each of whom the board has found to be independent and disinterested, that was formed for the purpose of evaluating the proposed merger and related transactions on behalf of the A. O. Smith Unaffiliated Stockholders.

The SICO board of directors, after careful consideration of a variety of factors, including the unanimous recommendation of the SICO Special Committee, recommends that SICO stockholders vote “FOR” the proposal to approve the Merger Agreement. See “The Merger—SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and SICO Board of Directors” beginning on page 66.

The SICO Special Committee is a committee of two members of SICO’s board of directors, each of whom the board has found to be independent and disinterested, that was formed for the purpose of evaluating the proposed merger and related transactions on behalf of the SICO Unaffiliated Stockholders.

Q.	What do I need to do now in order to vote?

A.	After you have carefully read this joint proxy statement/prospectus, please respond as soon as possible so that your shares will be represented and voted at your special meeting.

If you are an A. O. Smith stockholder, you may vote by:

•

submitting your proxy by Internet or telephone as described elsewhere in this joint proxy statement/prospectus and the proxy card; or

•

by completing, signing and dating your proxy card and returning it in the postage-paid envelope.

A. O. Smith stockholders of record may also attend the A. O. Smith special meeting and vote in person.

If you are a SICO stockholder you may vote by completing, signing and dating your proxy card and returning it in the postage-paid envelope. SICO stockholders of record will not be permitted to submit proxies by Internet or by telephone.

SICO stockholders of record may also attend the SICO special meeting and vote in person.

If you are a SICO stockholder as well as an A. O. Smith stockholder, you must vote separately at the special meeting of SICO stockholders in your capacity as a SICO stockholder and at the special meeting of A. O. Smith stockholders in your capacity as an A. O. Smith stockholder.

For additional information on voting procedures, see “The Special Meeting of A. O. Smith Stockholders” beginning on page 38 and “The Special Meeting of SICO Stockholders” beginning on page 46, as applicable.

Q.	How do I vote my shares if my shares are held in “street name”?

You should contact your broker or bank. Your broker or bank can give you directions on how to vote your shares. Your broker or bank will not vote your shares unless the broker or bank receives appropriate instructions from you. You should therefore provide your broker or bank with instructions as to how to vote your shares. For additional information on voting procedures, see “The Special Meeting of A. O. Smith Stockholders” beginning on page 38 and “The Special Meeting of SICO Stockholders” beginning on page 46, as applicable.

Q.	How will my shares be voted at the special meeting?

If you vote by completing, signing, dating and returning your signed proxy card, your shares will be voted in accordance with your instructions. If you are an A. O. Smith stockholder, you may also vote by Internet or telephone. If your proxy is properly executed and received (or, in the case of an A. O. Smith stockholder, properly submitted by Internet or telephone) in time to be voted at the special meeting, your shares represented by your proxy will be voted in accordance with your instructions. If you properly submit your proxy and do not indicate how you want to vote, your shares will be voted “FOR” adoption and approval of the applicable proposals. For additional information on voting procedures, see “The Special Meeting of A. O. Smith Stockholders” beginning on page 38 and “The Special Meeting of SICO Stockholders” beginning on page 46, as applicable.

Q.	Are any A. O. Smith stockholders already committed to vote in favor of the Merger Agreement, the A. O. Smith Amended Charter and the Stock Issuance?

Yes. In connection with the merger, A. O. Smith entered into a support agreement with SICO. Pursuant to this support agreement, SICO has agreed to vote its shares of A. O. Smith Class A common stock and A. O. Smith common stock in favor of the proposals to adopt the Merger Agreement, to adopt the A. O. Smith Amended Charter and to approve the Stock Issuance. SICO is the single largest stockholder of A. O. Smith, with beneficial ownership of approximately 8,067,052 shares (or approximately 97.9%) of outstanding A. O. Smith Class A common stock and 1,559,076 shares (or approximately 7.1%) of outstanding A. O. Smith common stock.

Because the shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO represent approximately 78.9% of the voting power of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, and 97.1% of the voting power of the total outstanding shares of A. O. Smith Class A common stock, voting as a separate class, stockholders of A. O. Smith holding voting power sufficient to approve the proposals to adopt the Merger Agreement, to adopt the A. O. Smith Amended Charter and to approve the Stock Issuance have agreed to vote in favor of these proposals at the A. O. Smith special meeting.

Q.	Are any SICO stockholders already committed to vote in favor of the Merger Agreement?

A.	Yes. In connection with the merger, SICO and A. O. Smith entered into a support agreement with certain members of the Smith Family who are holders of SICO common stock. Pursuant to this support agreement,

these members of the Smith Family have agreed to vote their shares of SICO common stock in favor of the proposal to approve the Merger Agreement. These members of the Smith Family, collectively, have beneficial ownership of approximately 1,748,044 shares (or approximately 52.7%) of the outstanding SICO common stock.

Because the shares of SICO common stock held by the members of the Smith Family who signed the Smith Family support agreement represent approximately 52.7% of the voting power of the outstanding shares of SICO common stock, stockholders of SICO holding voting power sufficient to approve the proposal to approve the Merger Agreement have agreed to vote in favor of the proposal to approve the Merger Agreement at the SICO special meeting.

•

Each holder of shares of A. O. Smith Class A common stock on the record date will be entitled to one vote for each share held of record upon each matter properly submitted at the special meeting of A. O.

Q.	If I am a holder of A. O. Smith Class A common stock who also owns A. O. Smith common stock, how do I vote?

If you hold A. O. Smith Class A common stock as well as A. O. Smith common stock, you must vote each class of shares separately for each proposal, in person or by proxy, at the special meeting of A. O. Smith stockholders. The separate vote of the holders of A. O. Smith Class A common stock is required in order to approve the A. O. Smith Amended Charter. Separate proxy cards for your shares of A. O. Smith Class A common stock and A. O. Smith common stock have been provided with this joint proxy statement/prospectus. For additional information, see “The Special Meeting of A. O. Smith Stockholders” beginning on page 38.

Q.	What if I want to change my vote after I have delivered my proxy card?

A.	You may change your vote at any time before your proxy is voted at the A. O. Smith special meeting. If you are the record holder of your shares of A. O. Smith common stock or A. O. Smith Class A common stock, you may change your vote in one of four ways:

•

first, you can send a written notice to A. O. Smith stating that you would like to revoke your proxy;

•

second, you can complete and submit a new valid proxy bearing a later date by mail or by Internet or telephone;

•

third, you can attend the A. O. Smith special meeting and vote in person; or

•

fourth, you can follow the instructions on the form you receive from your broker or bank with respect to changing or revoking your proxy if your shares of A. O. Smith Class A common stock and/or A. O. Smith common stock are held by a broker or bank.

Attendance at the A. O. Smith special meeting will not in and of itself constitute revocation of a proxy. If you hold shares of A. O. Smith common stock or A. O. Smith Class A common stock in “street name,” you should contact your broker or bank to give it instructions to change your vote.

If you are an A. O.

Questions and Answers for SICO Stockholders

Q.	What will SICO stockholders receive in the merger?

Upon completion of the merger, each issued and outstanding share of SICO common stock will be converted into the right to receive consideration in the form of shares of A. O. Smith Class A common stock and A. O. Smith common stock. For each issued and outstanding share of SICO common stock owned by a SICO stockholder, such stockholder will be entitled to receive:

•

the number of shares of A. O. Smith Class A common stock equal to the Class A Exchange Ratio;

•

the number of shares of A. O. Smith common stock equal to the Closing Common Exchange Ratio;

•

the number of shares of A. O. Smith common stock released from the escrow account, pursuant to the terms of the Merger Agreement and the escrow agreement, equal to the Per Share Escrow Release Number, if any; and

•

cash with respect to fractional shares, if any.

Assuming all of the shares of A. O. Smith common stock deposited into the escrow account are subsequently released to the former SICO stockholders, SICO stockholders will be entitled to receive (a) 2.396 shares of A. O. Smith Class A common stock and (b) 0.463 shares of A. O. Smith common stock for each share of SICO common stock that they hold, subject to the treatment of dissenting shares and fractional shares, if any.

The Merger Agreement provides that shares of A. O. Smith common stock having a fair market value of $15,000,000 (calculated in accordance with the Merger Agreement) will be deposited into the escrow account to provide a source of indemnification for A. O. Smith and its subsidiaries under the Merger Agreement. The number of Escrow Shares will vary based upon the average of the volume-weighted average price of trades for A. O. Smith common stock on the New York Stock Exchange for the ten trading days ending on the last trading day immediately preceding the effective time of the merger. Set forth below is a table showing a range of hypothetical volume-weighted average prices of A. O. Smith common stock along with the corresponding number of shares of A. O. Smith Class A common stock and A. O. Smith common stock that would be issued at the effective time of the merger and Escrow Shares per share of SICO common stock outstanding immediately prior to the effective time of the merger. For every $1.00 that the applicable volume-weighted average price of A. O. Smith common stock increases, the number of Escrow Shares decreases by approximately 0.005 of a share of A. O. Smith common stock for each share of SICO common stock, and the number of shares of A. O. Smith common stock issued at the effective time of the merger increases by approximately 0.005 of a share of A. O. Smith common stock for each share of SICO common stock. This table is for illustrative purposes only. The actual prices at which shares of A. O. Smith common stock trade during the ten trading days immediately preceding the effective time of the merger will determine the actual number of Escrow Shares, which may differ from the examples below. The actual number of Escrow Shares will not be determined until the last trading day immediately preceding the effective time of the merger.

Recommendations of the A. O. Smith Special Committee and A. O. Smith Board of Directors

The A. O. Smith Special Committee recommends that the A. O. Smith Unaffiliated Stockholders Vote “FOR” Adoption of the Merger Agreement and the A. O. Smith Board of Directors Recommends that all A. O. Smith Stockholders Vote “FOR” Adoption of the Merger Agreement, “FOR” Adoption of the A. O. Smith Amended Charter and “FOR” Approval of the Stock Issuance.

The A. O. Smith Special Committee is a committee of three independent and disinterested members of A. O. Smith’s board of directors that was formed for the purpose of evaluating the proposed merger and related transactions. On December 5, 2008, the A. O. Smith Special Committee unanimously determined that the merger, the terms of the Merger Agreement and the transactions contemplated thereby are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and the A. O. Smith Unaffiliated Stockholders, recommended that the A. O. Smith board of directors adopt, authorize and declare advisable the merger, the Merger Agreement and the other transactions contemplated by the Merger Agreement and recommended to the A. O. Smith Unaffiliated Stockholders that they vote in favor of adoption of the Merger Agreement.

On December 8, 2008, Morgan Stanley, independent financial advisor to the A. O. Smith Special Committee, rendered its oral opinion to the A. O. Smith Special Committee and the A. O. Smith board of directors, which opinion was subsequently confirmed in a written opinion dated as of December 9, 2008, to the effect that as of such date and based upon and subject to the various considerations set forth in the written opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith. The A. O. Smith Special Committee then reaffirmed its recommendations, and the A. O. Smith board of directors (with Mr. Bruce M. Smith and Mr. Mark D. Smith having recused themselves) considered the A. O. Smith Special Committee’s recommendation and reviewed the opinion rendered orally by Morgan Stanley. On December 9, 2008, the A. O. Smith board of directors again considered the A. O. Smith Special Committee’s recommendation and reviewed the opinion delivered by Morgan Stanley, and the A. O. Smith board of directors (with Mr. Bruce M. Smith and Mr. Mark D. Smith having recused themselves) approved the merger, the Merger Agreement and the other transactions contemplated by the Merger Agreement, determined that the merger, the Merger Agreement and the other transactions contemplated by the Merger Agreement are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and its stockholders (including the A. O. Smith Unaffiliated Stockholders) and recommended that all A. O. Smith stockholders vote in favor of the adoption of the Merger Agreement, adoption of the A. O. Smith Amended Charter and approval of the Stock Issuance.

In determining whether to recommend the approval of and to approve and adopt the Merger Agreement, the A. O. Smith Special Committee and A. O. Smith board of directors separately consulted with certain members of A. O. Smith’s senior management and with their legal and financial advisors. In arriving at their determination, the A. O. Smith Special Committee and A. O. Smith board of directors also considered the factors described under “The Merger—A. O. Smith’s Reasons for the Merger; Recommendations of the A. O. Smith Special Committee and A. O. Smith Board of Directors” beginning on page 62.

Recommendations of the SICO Special Committee and SICO Board of Directors

The SICO Special Committee Recommends that the SICO Unaffiliated Stockholders Vote “FOR” Approval of the Merger Agreement and the SICO Board of Directors Recommends that all SICO Stockholders Vote “FOR” Approval of the Merger Agreement.

The SICO Special Committee is a committee of two independent and disinterested members of SICO’s board of directors that was formed for the purpose of evaluating the proposed merger and related transactions. On December 9, 2008, the SICO Special Committee unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and substantively and procedurally fair to, and in the best interests of, SICO and the SICO Unaffiliated Stockholders, recommended that the SICO board of directors authorize, adopt and approve the Merger Agreement and the transactions contemplated by the Merger Agreement, including the merger, and recommended to the SICO Unaffiliated Stockholders that they vote in favor of approval of the Merger Agreement.

On December 9, 2008, SICO’s board of directors, after hearing and considering the SICO Special Committee’s recommendation, unanimously approved the Merger Agreement and the transactions contemplated thereby, including the merger, determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and substantively and procedurally fair to, and in the best interests of, SICO and its stockholders (including the SICO Unaffiliated Stockholders) and recommended that all SICO stockholders vote in favor of approval of the Merger Agreement.

In determining whether to approve the Merger Agreement, the SICO Special Committee and the SICO board of directors separately consulted with certain members of SICO’s senior management and with their legal and financial advisors. In arriving at their determination, the SICO Special Committee and the SICO board of directors also considered the factors described under “The Merger—SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and SICO Board of Directors” beginning on page 66.

Opinion of Morgan Stanley, Financial Advisor to the A. O. Smith Special Committee

On December 8, 2009, Morgan Stanley, independent financial advisor to the A. O. Smith Special Committee, rendered its oral opinion to the A. O. Smith Special Committee and the A. O. Smith board of directors, which opinion was subsequently confirmed in a written opinion dated as of December 9, 2008, to the effect that as of such date and based upon and subject to the various considerations set forth in the written opinion, the exchange ratio pursuant to the Merger Agreement was fair, from a financial point of view, to A. O. Smith. The full text of Morgan Stanley’s opinion is attached as Annex H to this joint proxy statement/prospectus, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Morgan Stanley in connection with its opinion. We urge you to read the opinion carefully in its entirety. The opinion of Morgan Stanley is addressed to the A. O. Smith Special Committee and the A. O. Smith board of directors and was one of many factors considered by the A. O. Smith Special Committee in deciding to recommend that the A. O. Smith Unaffiliated Stockholders adopt the Merger Agreement and that the A. O. Smith board of directors adopt the merger, the Merger Agreement and the other transactions contemplated thereby and by the A. O. Smith board of directors in deciding to adopt the Merger Agreement, the merger and the other transactions contemplated by the Merger Agreement and recommend stockholder approval. Additionally, the Morgan Stanley opinion addresses only the exchange ratio pursuant to the Merger Agreement and not the underlying decision by A. O. Smith to engage in the merger. Furthermore, the opinion does not constitute a recommendation to any A. O. Smith stockholder as to how that stockholder should vote at the special meeting of A. O. Smith stockholders or act on any matter relating to the merger.

Pursuant to an engagement letter with Morgan Stanley, A. O. Smith paid Morgan Stanley a $250,000 fee upon execution of the engagement letter and a $1,250,000 fee upon delivery of Morgan Stanley’s opinion in December 2008. An additional fee of $250,000 will be payable upon completion of the merger. Pursuant to its obligations under the Merger Agreement and a reimbursement agreement between SICO and A. O. Smith, SICO has reimbursed A. O. Smith for the first two payments.

See “The Merger—Opinion of Morgan Stanley, Financial Advisor to the A. O. Smith Special Committee” beginning on page 69.

Opinion of Duff & Phelps, Financial Advisor to the SICO Special Committee

Duff & Phelps, independent financial advisor to the SICO Special Committee, has provided an opinion to the SICO Special Committee, and upon which the SICO board of directors may rely, dated as of December 9, 2008, that, as of that date, and based on and subject to the qualifications and assumptions set forth in its opinion, the consideration to be received by the SICO Unaffiliated Stockholders in the merger was fair, from a financial point of view, to such holders. The full text of Duff & Phelps’ opinion is attached as Annex I to this joint proxy statement/prospectus, which sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Duff & Phelps in connection with its opinion. We urge you to read the opinion carefully in its entirety. The opinion of Duff & Phelps is addressed to the SICO Special Committee, and states that it may be relied upon by the SICO board of directors, and was one of many factors considered by the SICO Special Committee in deciding to recommend that the SICO board of directors approve the Merger Agreement and by the SICO board of directors in deciding to approve the Merger Agreement and the transactions contemplated thereby, including the merger. Additionally, the Duff & Phelps opinion addresses only the consideration to be received by the SICO Unaffiliated Stockholders in the merger and not the underlying decision by SICO to engage in the merger. Furthermore, the opinion does not constitute a recommendation to any SICO stockholder as to how that stockholder should vote at the special meeting of SICO stockholders or act on any matter relating to the merger.

Pursuant to an engagement letter with Duff & Phelps, SICO paid Duff & Phelps a $200,000 fee upon execution of its engagement letter and a $200,000 fee upon the SICO Special Committee’s request to deliver Duff & Phelps’ opinion in December 2008.

See “The Merger—Opinion of Duff & Phelps, Financial Advisor to the SICO Special Committee” beginning on page 73.

Interests of Executive Officers and Directors of A. O. Smith and SICO in the Merger

Stockholders should note that certain A. O. Smith directors and certain SICO directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of other A. O. Smith stockholders and SICO stockholders, respectively. Executive officers of A. O. Smith do not have interests in the merger that are different from, or in addition to, the interests of A. O. Smith stockholders generally.

The A. O. Smith Special Committee and the A. O. Smith board of directors were aware of these interests and considered them when (a) in the case of the A. O. Smith Special Committee, they voted to recommend that the A. O. Smith board of directors adopt, authorize and declare advisable the Merger Agreement, the merger and the related transactions and recommend to the A. O. Smith Unaffiliated Stockholders that they vote to adopt the Merger Agreement and (b) in the case of the A. O. Smith board of directors, they voted to adopt, authorize and declare advisable the Merger Agreement, the merger and the related transactions and recommend to A. O. Smith’s stockholders that they vote in favor of the adoption of the Merger Agreement, the merger and the related transactions. The SICO Special Committee and the SICO board of directors were aware of these interests and considered them when (a) in the case of the SICO Special Committee, they voted to recommend that the SICO board of directors authorize, adopt and approve the Merger Agreement and the transactions contemplated thereby, including the merger, and recommend to the SICO Unaffiliated Stockholders that they vote to approve the Merger Agreement and (b) in the case of the SICO board of directors, they voted to approve the Merger Agreement and the transactions contemplated thereby, including the merger, and to recommend that the SICO stockholders vote to approve the Merger Agreement.

At the close of business on , 2009, the record date for the special meeting of A. O. Smith stockholders, directors and executive officers of A. O. Smith, other than Bruce M. Smith and Mark D. Smith, had or shared the power to vote in the aggregate approximately shares of outstanding A. O. Smith common stock, or approximately % of the then outstanding A. O. Smith common stock, and shares of outstanding A. O. Smith Class A common stock, or approximately % of the then outstanding A. O. Smith Class A common stock.

At the close of business on , 2009, the record date for the special meeting of SICO stockholders, directors and executive officers of SICO, other than Bruce M. Smith, Arthur O. Smith and Arthur O. Smith III, had or shared the power to vote in the aggregate approximately shares of outstanding SICO common stock, or approximately % of the then outstanding SICO common stock.

For information relating to the interests of A. O. Smith’s directors in the merger, see “The Merger—Interests of A. O. Smith Executive Officers and Directors in the Merger” beginning on page 79, and for information relating to the interests of SICO’s executive officers and directors in the merger, see “The Merger—Interests of SICO Executive Officers and Directors in the Merger” beginning on page 80.

Regulatory Approvals Required for the Merger

Completion of the transactions contemplated by the Merger Agreement is subject to the receipt of approvals or consents from, or the making of filings with, various regulatory authorities, including the IRS and the NYSE. A. O. Smith and SICO currently are not aware of any additional required regulatory consents, approvals or filings. In the event any additional consents, approvals or filings are required, A. O. Smith and SICO presently contemplate that they will complete the filing of all of the required applications and notices with applicable regulatory authorities prior to the effective time of the merger. For information regarding regulatory approvals and filings, see “Regulatory Approvals” beginning on page 111.

Material United States Federal Income Tax Consequences of the Merger

There are no United States federal income tax consequences of the merger to A. O. Smith stockholders with respect to their shares of A. O. Smith Class A common stock or A. O. Smith common stock.

The merger is intended to constitute a tax-free reorganization for United States federal income tax purposes, and the obligations of SICO and A. O. Smith to effect the merger have been conditioned upon the receipt of the IRS Letter Ruling to that effect. Accordingly, we believe holders of SICO common stock will generally not recognize any gain or loss for United States federal income tax purposes on the exchange of their SICO common stock for A. O. Smith Class A common stock or A. O. Smith common stock in the merger, except for any gain or loss recognized in connection with any cash received instead of a fractional share of A. O. Smith Class A common stock or A. O. Smith common stock. Payments, if any, to the SICO stockholders for certain tax benefits of SICO will be taxable when paid. A. O. Smith, SICO and MergerCo themselves will not recognize gain or loss as a result of the merger.

Please refer to the section entitled “Material United States Federal Income Tax Consequences of the Merger” beginning on page 112 for a more complete discussion of the United States federal income tax consequences of the merger. Tax matters can be complicated and the tax consequences of the merger to you will depend on your particular tax situation. You should consult your tax advisor to determine the tax consequences of the merger to you.

Legal Proceedings Regarding the Merger

On February 26, 2008 a purported class action complaint was filed against SICO, certain SICO directors and officers, and A. O. Smith in the Milwaukee County Circuit Court in the State of Wisconsin.

The complaint claims, among other things, that SICO, certain directors and officers of SICO, and A. O. Smith “orchestrated the restructuring without due consideration or regard for the fiduciary duties owed to Plaintiff” and that the individual SICO directors and officers breached their fiduciary duties by self dealing. The lawsuit seeks an injunction requiring the defendants to provide all documents relevant to the terms and conditions of the proposed transaction and permitting the plaintiff to participate in all negotiations of the terms and conditions of the merger on behalf of the purported class of SICO stockholders. The lawsuit also seeks payment for all fees, costs and expenses incurred during the course of the litigation. On April 28, 2008, the parties stipulated that the litigation would be stayed until after SICO’s public announcement of the signing of a merger agreement with A. O. Smith and SICO’s dissemination of a definitive proxy statement with respect to a meeting of the SICO stockholders to consider the merger.

A. O. Smith, SICO, and the directors and officers of SICO named in the lawsuit believe the plaintiff’s claims are unsupported by the law or the facts and intend to defend themselves vigorously against these allegations. For further information regarding the foregoing lawsuit, please see “Risk Factors” beginning on page 29 and “The Merger—Legal Proceedings Regarding the Merger” beginning on page 84.

Appraisal Rights; Dissenter’s Rights

A. O. Smith stockholders do not have appraisal rights in connection with the merger and the other transactions contemplated by the Merger Agreement.

SICO stockholders who dissent from and do not approve the merger may be entitled to certain dissenters’ rights in connection with the merger. Stockholders who perfect their dissenters’ rights and strictly follow certain procedures in the manner prescribed by NRS 92A.300 to 92A.500 will be entitled to obtain payment of the fair value of their shares immediately before the effective time of the merger, excluding any appreciation or depreciation in anticipation of the merger.

NRS 92A.300 TO 92A.500 ARE REPRINTED IN THEIR ENTIRETY AS ANNEX J TO THIS JOINT PROXY STATEMENT/PROSPECTUS. ANY SICO STOCKHOLDER WHO WISHES TO EXERCISE DISSENTER’S RIGHTS OR WHO WISHES TO PRESERVE HIS OR HER RIGHT TO DO SO SHOULD REVIEW ANNEX J CAREFULLY AND SHOULD CONSULT HIS OR HER LEGAL ADVISOR, SINCE FAILURE TO TIMELY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

A VOTE IN FAVOR OF THE MERGER BY A SICO STOCKHOLDER MAY RESULT IN A LOSS OF SUCH HOLDER’S DISSENTER’S RIGHTS.

See “The Merger—Appraisal Rights; Dissenter’s Rights,” beginning on page 84 and Annex J to this joint proxy statement/prospectus.

SUMMARY UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION FOR SICO

The summary unaudited pro forma financial information set forth below should be read in conjunction with the unaudited pro forma condensed consolidated financial information, the consolidated financial statements and the related notes of SICO, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of SICO” appearing elsewhere in this joint proxy statement/prospectus. The summary unaudited pro forma financial information of SICO has been prepared giving effect to the Spin-Off and the merger as if these transactions occurred as of January 1, 2008 for the summary unaudited pro forma statements of operations data for the nine months ended September 30, 2008, as of January 1, 2008 for the summary unaudited pro forma statements of operations data for the year ended December 31, 2007; and as of September 30, 2008 for the summary unaudited pro forma balance sheet data as of September 30, 2008.

The summary unaudited pro forma condensed consolidated statements of operations data and the summary unaudited pro forma condensed consolidated balance sheet data have been derived from the unaudited pro forma condensed consolidated financial information, the audited consolidated financial statements and the unaudited condensed consolidated interim financial statements of SICO included elsewhere in this joint proxy statement/prospectus and do not purport to represent what SICO’s financial position and results of operations actually would have been had the Spin-Off, the merger and related transactions occurred on the dates indicated or to project SICO’s financial performance for any future period.

The transaction between A. O. Smith and SICO is considered a reverse acquisition under SFAS 141 (R) Business Combinations (“SFAS 141 (R)”). A reverse acquisition occurs when the legal acquirer, or the entity that issues the securities in the merger, is identified as the acquiree for accounting purposes. In the proposed merger, A. O. Smith is the legal acquirer because SICO will be a wholly owned subsidiary of A. O. Smith after the merger, and A. O. Smith will be issuing shares of A. O. Smith Class A common stock and A. O. Smith common stock as consideration in the merger. SICO is the legal acquiree in the merger. Even though A. O. Smith is the legal acquirer, SFAS 141(R) requires that A. O. Smith be treated as the acquiree for accounting purposes and SICO be treated as the acquirer for accounting purposes.

As the legal acquirer, however, A. O. Smith will survive as a publicly listed company after completion of the merger and will be required to present financial statement information in accordance with U.S. GAAP and SEC reporting requirements. SICO will have been merged with MergerCo, will cease to exist as an independent legal entity, and will be a wholly owned subsidiary of A. O. Smith after completion of the merger. Due to the reverse acquisition accounting treatment under SFAS 141(R), A. O. Smith’s financial statement information going forward will be presented as if SICO were the successor to the reporting obligation of A. O. Smith as of the date of the merger. As a result, prior period financial statement information presented in the A. O. Smith financial statements will reflect the historical activity of SICO.

In addition to being a reverse acquisition under SFAS 141(R), the merger is a common control transaction according to SFAS 160 Noncontrolling Interests in Consolidated Financial Statements an amendment of ARB No. 51 (“SFAS 160”). As a result, the merger will be accounted for as an equity transaction and therefore will not require purchase accounting adjustments to reflect fair value. Because A. O. Smith is the legal acquirer, the SICO shares are treated as having been converted to SICO’s ownership of A. O. Smith stock via a stock split to reflect SICO’s ownership of A. O. Smith Class A common stock and A. O. Smith common stock. Prior to the merger, SICO consolidated the financial results of A. O. Smith and presented a minority interest (referred to as a “noncontrolling interest” under SFAS 160). The noncontrolling interest represented the portion of A. O. Smith that SICO did not own. Under a reverse acquisition, the noncontrolling interest is eliminated from the financial statement presentation in future periods as A. O. Smith is the legal acquirer and the accounting acquiree. Although the non-SICO stockholders of A. O. Smith are not exchanging their shares in the merger, the reverse acquisition accounting requires the transaction to be presented as if an acquisition of the noncontrolling interest occurred since there is no remaining noncontrolling interest once the two companies are combined into one reporting entity.

COMPARATIVE PER SHARE DATA

The following table sets forth (a) certain historical per share information of A. O. Smith, (b) certain historical per share information of SICO and (c) unaudited pro forma per share information after giving effect to the merger as a reverse acquisition under SFAS 141(R) and a common control transaction in accordance with SFAS 160 Noncontrolling Interests in Consolidated Financial Statements and amendment of ARB No. 51 (SFAS 160). The unaudited pro forma condensed consolidated per share data assumes that, to give effect to the merger, each share of SICO common stock outstanding as of September 30, 2008 and December 31, 2007 was converted into (a) 2.396 shares of A. O. Smith Class A common stock and (b) 0.463 shares of A. O. Smith common stock, without regard to the treatment of Escrow Shares, dissenting shares and fractional shares described in this joint proxy statement/prospectus. The calculation of these exchange ratios assumes that all of the shares of A. O. Smith common stock deposited into the escrow account have been released to the former SICO stockholders. You should not rely on this information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that A. O. Smith or MergerCo will experience after the effective time of the merger. The unaudited pro forma condensed consolidated per share data have been derived from and should be read in conjunction with the “Unaudited Pro Forma Condensed Consolidated Financial Information for SICO” beginning on page PF-1. The historical per share data have been derived from the historical consolidated financial statements as of and for the periods indicated of A. O. Smith, as incorporated by reference in this joint proxy statement/prospectus, and of SICO, as set forth in this joint statement/prospectus beginning on page F-1.

Additional Dividend Information

A. O. Smith

A. O. Smith has paid dividends for 69 consecutive years. While A. O. Smith has paid dividends on its Class A common stock and its common stock, there is no assurance that it will continue to pay dividends in the future. The decision to pay dividends is within the discretion of the A. O. Smith board of directors and may be affected by various factors, including A. O. Smith’s earnings, financial condition, capital requirements, level of indebtedness and other considerations that the A. O. Smith board of directors deems relevant. A. O. Smith’s existing credit facility, as well as future credit facilities, other future debt obligations and statutory provisions may limit its ability to pay dividends.

SICO

SICO has paid dividends for 69 consecutive years. Dividends are generally paid by SICO on a quarterly basis after receipt by SICO of dividends on the shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO. The SICO board of directors has determined that SICO will not pay a dividend in the first quarter of 2009. In reaching its determination, the SICO board of directors considered the costs expected to be incurred to complete the merger and the desire of the SICO board of directors to preserve financial flexibility in light of current uncertainty in economic and financial conditions. The Merger Agreement does not limit the payment of dividends by SICO prior to the effective time as long as such dividends are made by SICO in the ordinary course consistent with past practices. The decision to pay dividends is within the discretion of the SICO board of directors. In determining whether to pay the second quarter 2009 dividend, if the merger has not been completed prior to such time, the SICO board of directors likely will take into account the financial condition of SICO and SpinCo, the costs incurred for the merger and the expectations of SICO stockholders, among other considerations.

Stockholder Information

A. O. Smith

As of January 27, 2009, A. O. Smith had 8,239,267 shares of A. O. Smith Class A common stock and 21,938,440 shares of A. O. Smith common stock outstanding and approximately 283 stockholders of record of A. O. Smith Class A common stock and 898 stockholders of record of A. O. Smith common stock. The numbers of stockholders of record do not reflect the number of persons or entities who may hold their stock in nominee or “street name” through brokerage firms.

SICO

As of January 27, 2009, SICO had 3,317,066 shares of SICO common stock outstanding and approximately 38 stockholders of record of SICO common stock. The number of stockholders of record does not reflect the number of persons or entities who may hold their stock in nominee or “street name” through brokerage firms.

RISK FACTORS

In addition to the other information contained in or incorporated by reference in this joint proxy statement/prospectus, including A. O. Smith’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007 and the matters addressed under the heading “Forward-Looking Statements” beginning on page 36 of this joint proxy statement/prospectus, you should carefully consider the following risk factors in deciding whether to vote in favor of the proposals described in this joint proxy statement/prospectus.

Risks Relating to the Merger

Completion of the merger is subject to the receipt of consents and approvals from, or the making of filings with, certain government entities that could delay completion of the merger or impose conditions that could have a material adverse effect on SICO or A. O. Smith, or significantly reduce the benefits expected to be obtained from the merger.

The merger is subject to the receipt of approvals or consent from, or the making of filings with, certain regulatory authorities, including the IRS, in connection with the request for the IRS Letter Ruling described in this joint proxy statement/prospectus. While we do not currently expect a delay in receiving the necessary approvals from such regulatory authorities, we cannot assure you that a delay will not occur. In addition to the required regulatory clearances and approvals, the merger is subject to a number of other conditions beyond our control that may prevent, delay or otherwise negatively affect its completion. See “The Merger Agreement—Conditions to Obligations to Complete the Merger” beginning on page 96. We cannot predict whether and when these other conditions will be satisfied. Any delay in completing the merger or the imposition of any additional material conditions on or changes to the terms of the merger may significantly reduce the benefits that we expect to achieve if we successfully complete the merger within the expected timeframe. See “Regulatory Approvals” beginning on page 111.

If the merger does not constitute a tax-free reorganization under Section 368(a) of the Code, then both SICO stockholders and A. O. Smith or MergerCo may be responsible for payment of income taxes.

The merger is conditioned upon the receipt by A. O. Smith and SICO of the IRS Letter Ruling to the effect that the merger will be treated as a tax-free reorganization within the meaning of Section 368(a) of the Code. Although a private letter ruling from the IRS generally is binding on the IRS, if the factual representations or assumptions made in the letter ruling request are untrue or incomplete, then the ruling may not be relied upon. If the merger were determined to be taxable, then both SICO stockholders and A. O. Smith or MergerCo (as successors to SICO) may be responsible for the payment of income taxes in connection with the merger.

The parties to the merger may fail to realize all of the expected benefits of the merger.

The parties to the merger may fail to realize some or all of the expected benefits of the transaction in the amounts and times projected for a number of reasons, including that the transaction may be more costly than expected or have unexpected adverse results.

The Merger Agreement limits the ability of A. O. Smith and SICO to pursue alternatives to the merger.

The Merger Agreement provides that neither of the boards of directors of SICO nor A. O. Smith, nor the A. O. Smith Special Committee nor the SICO Special Committee may withdraw or modify its recommendation regarding the merger. Notwithstanding the foregoing, at any time prior to the adoption of the Merger Agreement by its stockholders, the board of directors of either A. O. Smith or SICO, or duly constituted committees thereof, may withdraw or modify its recommendation regarding the merger in response to a material event relating to its business which is unknown to the board of directors as of the date of the Merger Agreement and which becomes known prior to the approval or adoption of the Merger Agreement by its stockholders, if the board of directors

(or committee thereof) determines in good faith, after consultation with its legal counsel and financial advisors, that the withdrawal or modification of the recommendation is required in order for the board of directors (or committee thereof) to comply with its fiduciary duties to its stockholders under applicable law. Regardless of whether the board of directors of A. O. Smith withdraws its recommendation regarding the merger as described in the sentence above, the board of directors of A. O. Smith may not cancel the special meeting of the A. O. Smith stockholders and is required to submit consideration of the merger and the related proposals to the A. O. Smith stockholders for a vote. The board of directors of SICO may withdraw its recommendation regarding the merger in accordance with the sentence above without any obligation to hold the special meeting of the SICO stockholders or submit consideration of the merger to the SICO stockholders for a vote. Certain members of the Smith Family who hold a majority of the outstanding shares of SICO common stock have agreed in a support agreement with SICO and A. O. Smith, for a period of one year after the termination of the Merger Agreement, not to vote in favor of any proposal that results in or is related to the withdrawal or modification of the SICO board recommendation. This agreement by the members of the Smith Family, along with the limitations in the Merger Agreement on withdrawing or modifying recommendations, may discourage third-parties from proposing alternative transactions to A. O. Smith or SICO. For a discussion of the limits on the ability of the board of directors of each of A. O. Smith and SICO to withdraw or modify its recommendation, see “The Merger Agreement—Obligations of each of the A. O. Smith and SICO Boards of Directors with Respect to its Recommendation and Holding a Meeting of its Stockholders” beginning on page 93. For a discussion of the Smith Family support agreement with SICO and A. O. Smith, see “Agreements Relating to the Merger—Smith Family Support Agreement” beginning on page 105.

Failure to complete the merger could negatively affect the stock price, future business and/or operations of SICO and the stock price of A. O. Smith.

The Merger Agreement contains a number of conditions to the obligations of the parties to complete the merger. In addition, the Merger Agreement may be terminated under certain circumstances. If the merger is not completed for any reason, SICO and A. O. Smith may be subject to a number of material risks. These risks include the following:

•

the market price of SICO common stock, A. O. Smith Class A common stock or A. O. Smith common stock may decline to the extent that the current market prices of SICO common stock, A. O. Smith Class A common stock or A. O. Smith common stock reflect a market assumption that the merger will be completed;

•

fees, costs and expenses incurred by SICO and A. O. Smith in connection with the merger, such as legal, accounting and certain financial advisor fees, costs and expenses, must be paid by SICO even if the merger is not completed; and

•

the Spin-Off has been completed and was not conditioned on the merger, and if the merger is not completed, SICO and SpinCo would continue as separate companies holding different portions of the assets and liabilities previously held by SICO, which could result in greater aggregate expenses and a greater administrative burden in managing the companies’ businesses, assets and liabilities.

If the Merger Agreement is terminated and SICO is required to pay the foregoing fees and expenses without realizing any of the benefits of the merger, it could have a material adverse effect on SICO’s business, financial condition and results of operations, which could ultimately affect the market price of SICO common stock.

Certain of A. O. Smith’s directors and SICO’s executive officers and directors have interests in the merger that are different from, or in addition to, the interests of A. O. Smith stockholders and SICO stockholders.

The A. O. Smith Special Committee and the SICO Special Committee negotiated the terms of the Merger Agreement. A. O. Smith’s board of directors approved and recommended that its stockholders vote to adopt the Merger Agreement, adopt the A. O. Smith Amended Charter and approve the Stock Issuance. SICO’s board of

directors approved and recommended that its stockholders vote to approve the Merger Agreement. Certain directors and/or executive officers may have interests in the merger that are different from, or in addition to, those of A. O. Smith and SICO stockholders generally. For additional information regarding such interests, see “The Merger—Interests of A. O. Smith Executive Officers and Directors in the Merger” beginning on page 79 and “The Merger—Interests of SICO Executive Officers and Directors in the Merger” beginning on page 80.

A. O. Smith and SICO are defendants in a pending lawsuit in connection with the merger.

On February 26, 2008, a purported class action complaint relating to the merger was filed against SICO, certain directors and officers of SICO, and A. O. Smith in the Milwaukee County Circuit Court in the State of Wisconsin.

While SICO, the directors and officers of SICO named in the lawsuit, and A. O. Smith believe that the allegations in the complaint are without merit and intend to defend vigorously against these allegations, we cannot assure you as to the outcome of this lawsuit, including the costs associated with defending this claim or any other liabilities or costs SICO or A. O. Smith may incur in connection with the litigation or settlement of this claim. The imposition of any additional material conditions on or changes to the terms of the merger may significantly reduce the benefits that A. O. Smith and SICO expect to achieve if they successfully complete the merger. A. O. Smith is entitled to indemnification by SpinCo and from the escrow fund for any costs, expenses or other amounts incurred, paid or payable in connection with this lawsuit or other claims related to the transactions contemplated by the Merger Agreement. For further information regarding the foregoing lawsuit, please see “The Merger—Legal Proceedings Regarding the Merger” beginning on page 84.

Risks Relating to the Merger for A. O. Smith Stockholders

MergerCo, as successor by merger to SICO, may remain liable to third parties after the merger.

Under the Merger Agreement, SpinCo has agreed to assume, and to indemnify A. O. Smith and its subsidiaries, including MergerCo, for all liabilities arising out of any events, conditions, circumstances, facts, activities, practices, actions or omissions with respect to SICO or its subsidiaries or SpinCo or any of their respective business operations which occurred prior to the merger. A. O. Smith and its subsidiaries, including MergerCo, also are indemnified for these liabilities from the escrow of shares of A. O. Smith common stock that otherwise would be issued to the SICO stockholders in the merger. See “Agreements Relating to the Merger—Escrow Agreement” beginning on page 107. SICO historically has been involved in multicolor printing and related services conducted through Berlin Industries, and commercial warehousing, trucking and packaging conducted through Central States. In addition, prior to 1998, SICO through its Belvedere division was engaged in the business of manufacturing and distributing equipment and fixtures for beauty and styling salons and barber shops. On January 19, 2009, SICO completed the Spin-Off. The Spin-Off is described in more detail in “The Companies—SICO—Recent Developments,” beginning on page 119. Notwithstanding the completion of the Spin-Off, MergerCo, as successor by merger to SICO, could continue to face possible liabilities with respect to the operations of Central States, Berlin Industries and the Belvedere division for actions, events or circumstances arising or occurring before the Spin-Off and the merger. The areas of potential liability include:

•

environmental cleanup costs and liabilities for claims made under federal, state or foreign environmental laws;

•

tax liabilities;

•

obligations under federal and state pension and retirement benefit laws; and

•

existing and future litigation, including litigation initiated in connection with the merger.

If SpinCo fails to indemnify A. O. Smith or MergerCo, as required under the Merger Agreement, for any of these liabilities and the value of the escrow fund is insufficient to satisfy these liabilities, A. O. Smith or MergerCo could incur material liabilities that may adversely affect A. O. Smith’s business and financial performance.

In the event SpinCo is unable to satisfy its indemnification obligations under the Merger Agreement, A. O. Smith’s and MergerCo’s right to indemnification under the Merger Agreement is limited to the escrow fund, which is limited in duration and may be insufficient to satisfy their claims.

In pursuing claims for indemnification under the Merger Agreement, A. O. Smith and MergerCo have agreed to proceed first against SpinCo and then, in the event SpinCo does not satisfy its indemnification obligations, against the escrow fund pursuant to the terms of the Escrow Agreement. Although SICO has represented to A. O. Smith that SpinCo will be solvent at the time of the merger, SpinCo has substantially smaller net assets than SICO did prior to the Spin-Off, because SICO retained its shares of A. O. Smith Class A common stock and A. O. Smith common stock. If A. O. Smith or MergerCo makes a claim for indemnification under the Merger Agreement, there is a risk that SpinCo may not have the financial capability to satisfy its indemnification obligations. The escrow fund initially will be funded with shares of A. O. Smith common stock with a market value of $15,000,000 as of the effective time of the merger. A. O. Smith cannot give any assurance that the value of the escrow fund will be sufficient to satisfy any potential indemnification claims of A. O. Smith or MergerCo under the Merger Agreement. The escrow agreement provides for the release of a substantial portion of the shares once certain legal proceedings relating to the transactions contemplated by the Merger Agreement have been resolved. In addition, the escrow fund terminates two years after the effective time, but the indemnification obligations of SpinCo under the Merger Agreement survive for five years after the effective time of the merger. As a result, A. O. Smith and MergerCo will not be able to look to the escrow fund for indemnification with respect to any claim that arises more than two years after the effective time of the merger.

If the market price of A. O. Smith common stock declines, the value of the escrow fund will also decline.

Under the terms of the Merger Agreement, shares of A. O. Smith common stock with a market value of $15,000,000 as of the effective time of the merger will be deposited with the escrow agent to provide a source of payment for the indemnification rights of A. O. Smith and MergerCo. The escrow agreement provides for the release of a substantial portion of the shares once certain legal proceedings relating to the transactions contemplated by the Merger Agreement have been resolved. The specific dollar value of the escrow fund, and therefore the amount of security provided to MergerCo and A. O. Smith, will depend on the market value of A. O. Smith common stock, which may decrease after the effective time of the merger. As a publicly traded company, the market price of A. O. Smith common stock is subject to fluctuations based on numerous factors. There is no requirement that additional shares or funds be placed in the escrow fund in the event the market price of A. O. Smith common stock decreases.

In addition, pursuant to the Escrow Agreement, SpinCo will have the right to substitute cash for all or a portion of the Escrow Shares on up to five separate occasions. The market value of any Escrow Shares that are released pursuant to any such cash substitution will be determined as of the effective time of the merger. Therefore, SpinCo will have the ability to substitute cash for the Escrow Shares if the market price of the A. O. Smith common stock increases in order to permit the former SICO stockholders to realize the benefit of the increased value of the shares, with no corresponding obligation to increase the escrow if the share price decreases.

If SICO stockholders who receive A. O. Smith Class A common stock and A. O. Smith common stock in the merger sell their shares, it could cause a decline in the market price of A. O. Smith Class A common stock or A. O. Smith common stock.

All of the shares of A. O. Smith Class A common stock and A. O. Smith common stock to be issued in the merger are being registered with the SEC under the registration statement of which this joint proxy statement/prospectus is a part, and therefore will be immediately available for resale in the public market, except with respect to shares issued in the merger to certain affiliates of A. O. Smith (as that term is defined in Rule 405 of the Securities Act of 1933, as amended (the “Securities Act”)). SICO has not sold any of its shares of A. O. Smith Class A common stock or A. O. Smith common stock during the past 16 years. After the merger is completed, each SICO stockholder will have the ability to determine if and when to sell the shares of A. O. Smith

Class A common stock and A. O. Smith common stock that the stockholder receives in the merger. If a large number of SICO stockholders elect to sell the shares they receive in connection with the merger, the market price of the A. O. Smith Class A common stock or the A. O. Smith common stock may decline. As a result of future sales of shares, or the perception that these sales could occur, the market price of A. O. Smith Class A common stock or A. O. Smith common stock may decline before or at the time the merger is completed, or thereafter.

Certain Smith Family members will have the ability to influence all matters requiring A. O. Smith stockholder approval.

The Merger Agreement contemplates that certain members of the Smith Family may enter into a voting trust agreement following the completion of the merger with respect to the A. O. Smith Class A common stock and A. O. Smith common stock they receive in the merger. After giving effect to the merger, these members of the Smith Family are expected to own approximately 41.4% of the total voting power of the outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, taken together as a single class, and approximately 51.6% of the voting power of the outstanding shares of A. O. Smith Class A common stock, as a separate class. This ownership position may increase if other members of the Smith Family enter into the voting trust agreement, and the voting power relating to this ownership position may increase if shares of A. O. Smith Class A common stock held by stockholders who are not parties to the voting trust agreement are converted into shares of A. O. Smith common stock. Accordingly, after the merger, the Smith Family members who enter into the voting trust agreement will collectively have the ability to influence the election of the Class A directors of A. O. Smith and other matters requiring A. O. Smith stockholder approval. The voting trust agreement provides that in the event one of the parties to the voting trust agreement desires to withdraw from the trust or transfer any of its shares of A. O. Smith Class A common stock, such shares of A. O. Smith Class A common stock are automatically exchanged for shares of A. O. Smith common stock held by the trust to the extent available in the trust. In addition, the trust will have the right to purchase the shares of A. O. Smith Class A common stock and A. O. Smith common stock proposed to be withdrawn or transferred from the trust. As a result, the Smith Family members that are parties to the voting trust agreement may have the ability to maintain their collective voting rights in A. O. Smith even if certain members of the Smith Family decide to transfer their shares.

The A. O. Smith Amended Charter will affect the rights of the stockholders of A. O. Smith Class A common stock.

The consummation of the merger is conditioned on, among other things, the adoption of the A. O. Smith Amended Charter, which will affect certain rights of the holders of A. O. Smith Class A common stock. The proposed A. O. Smith Amended Charter will provide, among other things, for

•

an increase in the percentage of members of the A. O. Smith board of directors that holders of A. O. Smith common stock elect;

•

shares of A. O. Smith Class A common stock to convert automatically into A. O. Smith common stock, subject to certain exceptions, upon transfer to unaffiliated third parties; and

•

all shares of A. O. Smith Class A common stock to convert automatically into A. O. Smith common stock once the outstanding shares of A. O. Smith Class A common stock falls below 2,397,976 shares, which is approximately 8% of the number of total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock as of the date of the Merger Agreement.

For additional information regarding the proposed changes to the A. O. Smith Existing Charter in connection with the merger, see the section entitled “A. O. Smith Amended Charter” beginning on page 102.

Risks Relating to the Merger for SICO Stockholders

SICO stockholders will receive a smaller number of shares in the merger than the total number of shares of A. O. Smith held by SICO.

The exchange ratio in the Merger Agreement reflects a discount of 1.5% such that the merger will result in the SICO stockholders receiving, in the aggregate, 98.5% of the total number of shares of each of the A. O. Smith Class A common stock and A. O. Smith common stock held by SICO prior to the effective time of the merger, subject to the treatment of Escrow Shares, fractional shares and dissenting shares described in this joint proxy statement/prospectus. Based on the closing price of $ of the A. O. Smith common stock on the NYSE on , 2009, the last full trading day for which closing prices were available at the time of the printing of this joint proxy statement/prospectus, and valuing the A. O. Smith Class A common stock at such value as if it had been converted into A. O. Smith common stock, the aggregate value of the shares reflected in this 1.5% discount was $ million.

Shares of A. O. Smith common stock deposited in escrow in connection with the merger will be at risk for post-closing indemnification claims by A. O. Smith or the other A. O. Smith indemnified parties.

At the effective time of the merger, A. O. Smith will deposit with the escrow agent a number of shares of A. O. Smith common stock that would otherwise be deliverable to the holders of SICO common stock pursuant to the Merger Agreement with a market value of $15,000,000 as of the effective time of the merger. These shares of A. O. Smith common stock may not be transferred as long as they remain in escrow and will be subject to release to A. O. Smith or the other A. O. Smith indemnified parties to the extent any of them has a right to indemnification for damages that are not satisfied by SpinCo for a period of two years after the effective time of the merger. For a description of the escrow, please refer to “Agreements Relating to the Merger—Escrow Agreement” beginning on page 107.

If the market price of A. O. Smith common stock declines, SICO and A. O. Smith may be unable to terminate the Merger Agreement and SICO stockholders will receive shares with a lower market value in connection with the merger.

The consideration to be issued to SICO stockholders in connection with the merger, for each issued and outstanding share of SICO common stock that they own, will consist of a fixed number of shares of A. O. Smith Class A common stock and A. O. Smith common stock calculated in accordance with the Merger Agreement based upon the number of shares of SICO common stock outstanding and the number of shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO immediately prior to the effective time of the merger. See “The Merger Agreement—Consideration to be Received in the Merger” beginning on page 87. There will be no adjustment to the number of shares of A. O. Smith Class A common stock or A. O. Smith common stock issued to the SICO stockholders in connection with the merger based upon changes in the market price of A. O. Smith Class A common stock or A. O. Smith common stock prior to the effective time of the merger. In addition, neither SICO nor A. O. Smith may terminate the Merger Agreement or “walk away” from the merger due to changes in the market price of A. O. Smith common stock. As a result, the specific dollar value of the consideration that the SICO stockholders will receive in connection with the merger will depend on the market value of A. O. Smith Class A common stock and A. O. Smith common stock, and may decrease from the date the SICO stockholders submit their proxies. As a publicly traded company, the market price of A. O. Smith Class A common stock and A. O. Smith common stock is subject to fluctuations based on numerous factors. See “The Merger Agreement—Consideration to be Received in the Merger” beginning on page 87 and “Agreements Relating to the Merger—Escrow Agreement” beginning on page 107.

A. O. Smith cannot predict or give any assurances as to the market price of the A. O. Smith Class A common stock or the A. O. Smith common stock at any time before or after the completion of the merger. SICO stockholders should obtain recent market quotations for A. O. Smith Class A common stock and A. O. Smith common stock in making a determination on whether to vote in favor of the adoption or approval of the Merger Agreement.

The rights of SICO stockholders who become A. O. Smith stockholders in the merger will be governed by the A. O. Smith Amended Charter and A. O. Smith’s bylaws.

SICO stockholders who receive shares of A. O. Smith Class A common stock and A. O. Smith common stock in the merger will become A. O. Smith stockholders. Following the merger, their rights as stockholders will be subject to the Delaware General Corporation Law (“DGCL”), and they will be governed by the A. O. Smith Amended Charter and A. O. Smith’s bylaws, rather than SICO’s articles of incorporation and bylaws.

A copy of the Merger Agreement is attached to this joint proxy statement/prospectus as Annex A and is made part of this joint proxy statement/prospectus.

Record Date and Voting

The A. O. Smith board of directors has fixed , 2009 as the record date for determining the holders of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock entitled to receive notice of and to vote at the special meeting of A. O. Smith stockholders or any adjournment or postponement of the special meeting. Only holders of record of A. O. Smith Class A common stock and A. O. Smith common stock as of the close of business on that date will be entitled to vote at the special meeting of A. O. Smith stockholders and at any adjournment or postponement of that meeting. As of the close of business on , 2009, there were shares of A. O. Smith Class A common stock and shares of A. O. Smith common stock outstanding, held by approximately and holders of record, respectively.

Each holder of shares of A. O. Smith Class A common stock will be entitled to one vote for each share held of record upon each matter properly submitted at the special meeting of A. O. Smith stockholders and at any adjournment or postponement of that meeting. Each holder of shares of A. O. Smith common stock outstanding on the record date will be entitled to 1/10th of a vote for each share held of record upon each matter properly submitted at the special meeting of A. O. Smith stockholders and at any adjournment or postponement of that meeting. In order for A. O. Smith to satisfy its quorum requirements, the holders of at least a majority of the total number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock entitled to vote at the special meeting of A. O. Smith stockholders must be present. You will be deemed to be present at the special meeting of A. O. Smith stockholders if you attend the meeting or if you submit a proxy (including through the Internet or telephone) that is received at or prior to the special meeting of A. O. Smith stockholders

(and not revoked as described below). IF YOU ARE A SICO STOCKHOLDER AS WELL AS AN A. O. SMITH STOCKHOLDER, YOU MUST VOTE SEPARATELY AT THE SPECIAL MEETING OF SICO STOCKHOLDERS IN YOUR CAPACITY AS A SICO STOCKHOLDER AND AT THE SPECIAL MEETING OF A. O. SMITH STOCKHOLDERS IN YOUR CAPACITY AS AN A. O. SMITH STOCKHOLDER.

If your proxy is properly executed and received by A. O. Smith in time to be voted at the special meeting of A. O. Smith stockholders, the shares represented by your proxy (including those given through the Internet or by telephone) will be voted in accordance with the instructions that you mark on your proxy. If you execute your proxy but do not provide A. O. Smith with any instructions, your shares will be voted “FOR” the adoption of the Merger Agreement, “FOR” the adoption of the A. O. Smith Amended Charter and “FOR” the approval of the Stock Issuance.

Vote Required

Adoption of the Merger Agreement requires the affirmative vote of the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing at least 66²/₃% of the votes represented by the total number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock.

Adoption of the A. O. Smith Amended Charter requires the affirmative vote of the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing a majority of the votes represented by the total number of the outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock.

Adoption of the A. O. Smith Amended Charter also requires the affirmative vote of the holders of a majority of the outstanding shares of A. O. Smith Class A common stock voting as a separate class.

Approval of the Stock Issuance requires the affirmative vote of the holders of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, representing a majority of the votes cast by such holders at the special meeting.

Shares of A. O. Smith common stock as to which the “abstain” box is selected on a proxy card will be counted as present for purposes of determining whether a quorum is present.

The required vote of A. O. Smith stockholders to adopt the Merger Agreement is based upon the votes represented by the number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, and not the number of shares that are actually voted. Accordingly, the failure to submit a proxy card or to vote by Internet, telephone or in person at the special meeting of A. O. Smith stockholders or the abstention from voting by A. O. Smith stockholders, or the failure of any A. O. Smith stockholder who holds shares in “street name” through a bank or broker to give voting instructions to such bank or broker, will have the same effect as a vote “AGAINST” the proposal to adopt the Merger Agreement.

The required vote of A. O. Smith stockholders to adopt the A. O. Smith Amended Charter is based upon the votes represented by the number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, and not the number of shares that are actually voted. Accordingly, the failure to submit a proxy card or to vote by Internet, telephone or in person at the special meeting of A. O. Smith stockholders or the abstention from voting by A. O. Smith stockholders, or the failure of any A. O. Smith stockholder who holds shares in “street name” through a bank or broker to give voting instructions to such bank or broker, will have the same effect as a vote “AGAINST” the proposal to adopt the A. O. Smith Amended Charter.

The required vote of A. O. Smith stockholders to approve the Stock Issuance is based on the number of shares that are actually voted, not on the number of outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock. Accordingly, the failure to submit a proxy card or to vote by Internet, telephone or in person at the special meeting of A. O. Smith stockholders or the abstention from voting by A. O. Smith stockholders, or the failure of any A. O. Smith stockholder who holds shares in “street name” through a bank or broker to give voting instructions to such bank or broker, will have no effect on the result of the vote to approve the Stock Issuance.

As of the record date, A. O. Smith directors and executive officers and their affiliates, other than Bruce M. Smith and Mark D. Smith, had or shared the power to vote in the aggregate approximately shares of A. O. Smith Class A common stock, shares of A. O. Smith common stock and total aggregate shares of A. O. Smith Class A common stock and A. O. Smith common stock, representing approximately %, % and % of the aggregate outstanding shares of A. O. Smith Class A common stock, A. O. Smith common stock and total aggregate A. O. Smith Class A common stock and A. O. Smith common stock, respectively.

We have been advised that A. O. Smith’s directors and executive officers will vote their shares of A. O. Smith common stock “FOR” the adoption of the Merger Agreement, “FOR” the adoption of the A. O. Smith Amended Charter and “FOR” the approval of the Stock Issuance.

Because the shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO represent approximately 78.9% of the voting power of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, and approximately 97.1% of the voting power of the total outstanding shares of A. O. Smith Class A common stock, voting as a separate class, stockholders of A. O. Smith holding voting power sufficient to approve the proposals to adopt the Merger Agreement, to adopt the A. O. Smith Amended Charter and to approve the Stock Issuance have agreed to vote in favor of these proposals at the A. O. Smith special meeting.

Recommendations of the A. O. Smith Special Committee and A. O. Smith Board of Directors

As discussed elsewhere in this joint proxy statement/prospectus, the A. O. Smith Special Committee unanimously determined that the Merger Agreement is advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and the A. O. Smith Unaffiliated Stockholders and the A. O. Smith board of directors has determined that the merger, the Merger Agreement and the transactions contemplated thereby are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and the A. O. Smith stockholders, including the A. O. Smith Unaffiliated Stockholders, and has adopted and approved the merger, the Merger Agreement and the transactions contemplated thereby, the A. O. Smith Amended Charter and the Stock Issuance. The A. O. Smith Special Committee recommends that the A. O. Smith Unaffiliated Stockholders vote “FOR” the adoption of the Merger Agreement. The A. O. Smith board of directors recommends that A. O. Smith stockholders vote “FOR” the adoption of the Merger Agreement, “FOR” the adoption of the A. O. Smith Amended Charter and “FOR” the approval of the Stock Issuance.

THE SPECIAL MEETING OF SICO STOCKHOLDERS

General

This joint proxy statement/prospectus is being furnished to SICO stockholders in connection with the solicitation of proxies by the SICO board of directors to be used at the special meeting of SICO stockholders to be held on , 2009 at a.m./p.m., Central Daylight Saving Time, at , and at any adjournment or postponement of that meeting. This joint proxy statement/prospectus and the enclosed proxy card are being mailed to SICO’s stockholders on or about , 2009.

Purpose of the Special Meeting of SICO Stockholders

At the special meeting of SICO stockholders, holders of SICO common stock will be asked to consider and vote on the following proposals to:

•

approve the Merger Agreement; and

•

transact any other business as may be properly brought before the special meeting of SICO stockholders.

The approval of the first proposal listed above is required for completion of the merger. See “SICO Proposal 1—Approval of the Merger Agreement” on page 50. A copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus and made part of this joint proxy statement/prospectus.

Record Date and Voting

The SICO board of directors has fixed , 2009 as the record date for determining holders of outstanding shares of SICO common stock entitled to receive notice of and to vote at the special meeting of SICO stockholders or any adjournment or postponement of the special meeting. Only holders of record of SICO common stock as of the close of business on that date will be entitled to vote at the special meeting of SICO stockholders and at any adjournment or postponement of that meeting. As of the close of business on , 2009, there were shares of SICO common stock outstanding, held by approximately holders of record. SICO’s common stock is the only class of outstanding securities entitled to notice of, and to vote at, the SICO special meeting.

Each holder of shares of SICO common stock will be entitled to one vote for each share held of record upon any matter properly submitted at the special meeting of SICO stockholders and at any adjournment or postponement of that meeting. In order for SICO to satisfy its quorum requirements, the holders of at least a majority of the total number of outstanding shares of SICO common stock entitled to vote at the special meeting of SICO stockholders must be present. You will be deemed to be present at the special meeting of SICO stockholders if you attend the meeting or if you submit a proxy card that is received at or prior to the special meeting of SICO stockholders (and not revoked as described below). IF YOU ARE AN A. O. SMITH STOCKHOLDER AS WELL AS A SICO STOCKHOLDER, YOU MUST VOTE SEPARATELY AT THE SPECIAL MEETING OF A. O. SMITH STOCKHOLDERS IN YOUR CAPACITY AS AN A. O. SMITH STOCKHOLDER AND AT THE SPECIAL MEETING OF SICO STOCKHOLDERS IN YOUR CAPACITY AS A SICO STOCKHOLDER.

If your proxy card is properly executed and received by SICO in time to be voted at the special meeting of SICO stockholders, the shares represented by your proxy card will be voted in accordance with the instructions that you mark on your proxy card. If you execute your proxy card but do not provide SICO with any instructions, your shares will be voted “FOR” the approval of the Merger Agreement.

Vote Required

Approval of the Merger Agreement requires the affirmative vote of the holders of a majority of the shares of SICO common stock outstanding on the record date and entitled to vote at the special meeting.

Shares of SICO common stock as to which the “abstain” box is selected in a proxy card will be counted as present for purposes of determining whether a quorum is present. The required vote of SICO stockholders to approve the Merger Agreement is based upon the number of outstanding shares of SICO common stock, and not the number of shares that are actually voted. Accordingly, the failure to submit a proxy card or to vote in person at the special meeting of SICO stockholders or the abstention from voting by SICO stockholders, or the failure of any SICO stockholder who holds shares in “street name” through a bank or broker to give voting instructions to such bank or broker, will have the same effect as a vote “AGAINST” the proposal to approve the Merger Agreement.

As of the record date, SICO directors and executive officers and their affiliates had or shared the power to vote in the aggregate approximately shares of SICO common stock, representing approximately % of the aggregate outstanding shares of SICO common stock. This calculation excludes shares that may be deemed to be beneficially owned by Bruce M. Smith, Arthur O. Smith and Arthur O. Smith, III, which are subject to the Smith Family support agreement and included below.

We have been advised that SICO’s directors and executive officers will vote their shares of SICO common stock “FOR” the approval of the Merger Agreement.

Because the shares of SICO common stock held by the Smith Family stockholders who signed the Smith Family support agreement represent approximately 52.7% of the voting power of the total outstanding shares of SICO common stock, stockholders of SICO holding voting power sufficient to approve the Merger Agreement have agreed to vote in favor of the proposal to approve the Merger Agreement at the SICO special meeting.

Recommendations of the SICO Special Committee and SICO Board of Directors

The SICO Special Committee unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and substantively and procedurally fair to, and in the best interests of, SICO and the SICO Unaffiliated Stockholders and recommended that the SICO board of directors authorize, adopt and approve the Merger Agreement and the transactions contemplated thereby, including the merger. The SICO Special Committee unanimously recommends that the SICO Unaffiliated Stockholders vote “FOR” the approval of the Merger Agreement at the special meeting of the SICO stockholders.

The SICO board of directors approved the Merger Agreement and determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and substantively and procedurally fair to, and in the best interests of, SICO and the SICO stockholders, including the SICO Unaffiliated Stockholders. The SICO board of directors unanimously recommends that SICO’s stockholders vote “FOR” the approval of the Merger Agreement at the special meeting of the SICO stockholders.

The matters to be considered at the SICO special meeting are of great importance to the stockholders of SICO. Accordingly, you are urged to read and carefully consider the information presented in this joint proxy statement/prospectus, and to complete, date, sign and promptly return the enclosed proxy in the enclosed postage-paid envelope. In particular, SICO stockholders are directed to the Merger Agreement, which is attached as Annex A to this joint proxy statement/prospectus.

Stockholders will not be allowed to use cameras, recording devices and other electronic devices at the meeting.

Voting by Proxy

Stockholders who elect to vote by proxy are asked to mark the box on the proxy card, following the instructions on your proxy card, to indicate how to vote your shares. You must also sign, date and return the enclosed proxy card using the postage-paid envelope provided. All shares represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the stockholders giving those proxies. Properly executed proxies that do not contain voting instructions will be voted “FOR” the approval of the Merger Agreement.

Stockholders of record will not be permitted to submit proxies electronically or by telephone. If your shares are held in the name of a bank or broker, the availability of electronic or telephone voting will depend upon the voting processes of the bank or broker. Accordingly, stockholders should follow the voting instructions on the form they receive from their bank or broker.

Revocation of Proxies

The presence of a SICO stockholder at the special meeting of SICO stockholders will not automatically revoke the SICO stockholder’s proxy. However, a SICO stockholder may revoke his or her proxy at any time prior to its exercise by:

•

delivering a written notice of revocation to SICO’s Corporate Secretary that is received prior to the SICO special meeting;

•

submitting another proxy that is dated later than the original proxy and that is received prior to the SICO special meeting;

•

attending the special meeting of SICO stockholders and voting in person if your shares of SICO common stock are registered in your name rather than in the name of a broker or bank; or

SICO stockholders should read carefully this joint proxy statement/prospectus in its entirety for more detailed information concerning the Merger Agreement. In particular, SICO stockholders are directed to the Merger Agreement, which is attached as Annex A to this joint proxy statement/prospectus. Additionally, please refer to the section entitled “The Merger Agreement” beginning on page 87 for a summary of the material terms of the Merger Agreement.

THE SICO BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR”

THE APPROVAL OF THE MERGER AGREEMENT.

THE MERGER

Background of the Merger

From time to time, SICO has reviewed alternatives to address its concern that the SICO common stock historically has traded at a significant discount to the underlying value of SICO’s most significant asset – the shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO.

In August 2007, SICO engaged Latham as its outside legal advisor to assist SICO and the SICO board of directors in a review of possible transactions involving SICO’s holdings in A. O. Smith. SICO articulated the following objectives for a possible transaction:

•

providing the stockholders of SICO with direct ownership of A. O. Smith shares, which would allow SICO’s stockholders to realize more fully the underlying value of SICO’s holdings in A. O. Smith, provide enhanced liquidity to SICO’s stockholders and provide SICO’s stockholders with direct payment of the full amount of any dividends paid by A. O. Smith;

•

utilizing a transaction structure that would constitute a tax-free reorganization under the Code; and

•

providing flexibility for SICO to enhance the value of its other businesses.

During the fall of 2007, SICO’s management and representatives of Latham reviewed and evaluated various possible transactions, in light of these stated objectives.

On October 30, 2007, the SICO board of directors met with members of SICO’s management to discuss the status of SICO’s review of possible transactions. The SICO board of directors discussed the potential interests of the SICO directors who are trustees or beneficiaries of certain trusts for members of the Smith Family, or who otherwise have relationships with A. O. Smith or members of the Smith Family, that could be deemed to conflict with the interests of the SICO Unaffiliated Stockholders. Because of these interests, Latham recommended that the SICO board of directors form a special committee to act in the interests of the SICO Unaffiliated Stockholders with respect to any potential transaction. Edward E. Barr and Harold M. Stratton II were discussed as possible members of the SICO Special Committee. The SICO board of directors determined to continue the review process, and SICO’s management was instructed to work with Latham to evaluate further the potential mandate and scope of authority for the SICO Special Committee, and to confirm the eligibility of Messrs. Barr and Stratton to serve on the SICO Special Committee.

On December 18, 2007, the SICO board of directors met to consider transaction alternatives. Latham reviewed two transaction alternatives with the SICO board of directors: a merger of SICO into a newly formed limited liability company subsidiary of A. O. Smith and a transfer of assets of SICO to A. O. Smith. Both of these transaction alternatives could qualify as a tax-free reorganization, although the asset transfer structure had additional restrictions to qualify as a tax-free reorganization. The SICO board of directors established the SICO Special Committee and designated Messrs. Barr and Stratton as the members of the SICO Special Committee. Mr. Barr was later designated as the Chairman of the SICO Special Committee. The SICO Special Committee was delegated the authority to (a) determine the advisability of a potential transaction, (b) consider alternatives to a potential transaction, including not pursuing any transaction, (c) review, evaluate and establish the terms and conditions of a potential transaction or any alternative, (d) negotiate with members of the Smith Family, A. O. Smith and any other party regarding the terms and conditions of a potential transaction or any alternative, and (e) determine whether a potential transaction or any alternative was advisable, fair to and in the best interests of the SICO Unaffiliated Stockholders. The SICO board of directors further provided that it would not recommend any potential transaction or alternative for approval by SICO’s stockholders without a prior favorable recommendation of the SICO Special Committee. The SICO Special Committee determined to engage Reinhart as its independent legal counsel.

The SICO Special Committee held a telephonic meeting with Reinhart on December 21, 2007, to discuss various alternatives for a potential transaction and related issues. The SICO Special Committee also discussed

potential candidates to serve as independent financial advisor to the committee and the criteria for the selection of an investment banking firm to serve as independent financial advisor to the committee. On January 4, 2008, the SICO Special Committee and its legal counsel interviewed candidates to serve as independent financial advisor to the committee, and the SICO Special Committee determined to engage Duff & Phelps.

On January 21, 2008, the SICO Special Committee met at Reinhart’s offices with representatives of Duff & Phelps and Reinhart. Reinhart made a presentation to the SICO Special Committee addressing the role and authority of the committee, the two potential transaction structures that had been identified and the considerations and objectives for a potential transaction. The SICO Special Committee discussed the issues and risks with satisfying the test for an asset transfer to qualify as a tax-free reorganization, and decided against further consideration of an asset transfer given the additional restrictions for that transaction structure. The SICO Special Committee also discussed alternatives for SICO’s two operating subsidiaries, including distributing them to the SICO stockholders in a spin-off transaction.

Duff & Phelps next made a presentation to the SICO Special Committee. Duff & Phelps addressed two possible alternative transactions: (a) a recapitalization of A. O. Smith that would eliminate the A. O. Smith Class A common stock and (b) a sale of SICO to a third party. During the ensuing discussion, the SICO Special Committee recognized that, if members of the Smith Family did not support either of these transaction alternatives, pursuing one or both of these alternatives would be futile because members of the Smith Family control a majority of the outstanding shares of SICO common stock. The SICO Special Committee instructed its legal and financial advisors to continue to explore these alternatives.

On January 22, 2008, the SICO Special Committee reported on its progress during a meeting of the full SICO board of directors. The SICO Special Committee indicated that it believed it would be in a position to make a recommendation by February 1, 2008.

Between January 22, 2008 and February 1, 2008, the SICO Special Committee’s legal and financial advisors continued to explore transaction alternatives and related issues. During this period, it was decided that the members of the SICO Special Committee would consult with members of the Smith Family holding a majority of the outstanding shares of SICO common stock to determine which transaction alternatives they would support. Separate meetings with these members of the Smith Family were scheduled for February 1, 2008. On January 30, 2008, the SICO Special Committee held a telephonic meeting with its legal counsel to discuss the process and objectives for the meetings with members of the Smith Family.

On February 1, 2008, the SICO Special Committee and its legal counsel held separate meetings with certain members of the Smith Family, including the trustees of various trusts. These members of the Smith Family collectively owned and continue to own more than 50% of the outstanding shares of SICO common stock. During these meetings, these members of the Smith Family separately indicated that they would support the proposed transaction with A. O. Smith and also separately indicated that they would not support any alternative transaction that resulted in a sale of SICO or eliminated or limited the dual class voting structure of A. O. Smith.

After the meetings with members of the Smith Family, the SICO Special Committee met on February 1, 2008, to discuss its recommendation with respect to a potential transaction. The SICO Special Committee recognized that a merger transaction with A. O. Smith resulting in the issuance directly to the SICO stockholders of the same aggregate number and type of shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO would provide significant benefits to the SICO Unaffiliated Stockholders, including increased liquidity, the expected elimination of the discount between the market capitalization of SICO and the value of its holdings of A. O. Smith Class A common stock and A. O. Smith common stock and qualification as a tax-free reorganization under the Code. The members of the SICO Special Committee unanimously resolved to recommend to the SICO board of directors a proposal for a merger transaction with A. O. Smith, in which SICO’s stockholders would receive the same type and number of A. O. Smith shares held by SICO.

After the meeting of the SICO Special Committee, the SICO board of directors held a telephonic meeting on February 1, 2008. The SICO Special Committee presented its recommendation to the SICO board of directors, after which the SICO board of directors unanimously approved making a proposal to A. O. Smith for a merger transaction, with SICO’s stockholders receiving the same type and number of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO.

On February 2, 2008, Bruce M. Smith, SICO’s President and Chief Executive Officer, and Mr. Barr met with Paul W. Jones, Chairman of the board of directors and Chief Executive Officer of A. O. Smith, to present SICO’s proposal. SICO proposed that SICO be merged into a newly formed subsidiary of A. O. Smith and that, in the merger, SICO’s outstanding common stock be exchanged for newly issued shares of A. O. Smith Class A common stock and A. O. Smith common stock. The proposed total number and type of A. O. Smith shares to be issued in the proposed transaction equaled the number and type of A. O. Smith shares held by SICO, so that there would be no net change in the total number and type of shares of A. O. Smith stock. The merger was intended to qualify as a tax-free reorganization under Section 368(a) of the Code. Prior to the merger, SICO would distribute in a taxable transaction substantially all of its assets, other than its holdings of A. O. Smith shares, to SICO’s stockholders. SICO’s liabilities would be discharged or otherwise assumed by the entity or entities in which the other SICO assets were to be held.

On the following Monday, February 4, 2008, before the markets opened, SICO and A. O. Smith each issued a press release to announce that A. O. Smith had received the proposal from SICO and to provide details of the proposal. SICO also filed an amendment to its Schedule 13D.

At a meeting held on February 10, 2008, the A. O. Smith board of directors (other than Bruce M. Smith and Mark D. Smith who recused themselves) discussed the proposal received from SICO. At this meeting, James F. Stern, Executive Vice President, General Counsel and Secretary of A. O. Smith, recommended that the A. O. Smith board of directors appoint a special committee of independent and disinterested directors to consider the SICO proposal, among other reasons, because SICO is the controlling stockholder of A. O. Smith and certain members of the A. O. Smith board of directors are affiliated with SICO. At a meeting of the A. O. Smith board of directors (other than Bruce M. Smith and Mark D. Smith who recused themselves) on February 12, 2008, the A. O. Smith board of directors determined that it was appropriate to form and authorized the creation of a special committee of independent and disinterested directors, consisting of William Greubel, Idelle Wolf and Ronald Brown. Mr. Stern confirmed the eligibility of Messrs. Greubel and Brown and Ms. Wolf to serve on the A. O. Smith Special Committee. The A. O. Smith Special Committee was authorized to, among other things, review and evaluate SICO’s proposed transaction, negotiate the terms and conditions of any transaction, determine whether the proposed transaction (as it may be amended or modified by the A. O. Smith Special Committee) was fair to, and in the best interests of, A. O. Smith and the A. O. Smith Unaffiliated Stockholders and provide a recommendation to the A. O. Smith board of directors as to whether it should approve the proposed transaction. The A. O. Smith board of directors also authorized the A. O. Smith Special Committee to retain independent legal and financial advisors selected by the A. O. Smith Special Committee. At a subsequent meeting of the A. O. Smith board of directors held on April 15, 2008, the A. O. Smith board of directors affirmed that it would not recommend any potential transaction with SICO without a prior favorable recommendation of the A. O. Smith Special Committee.

On February 12, 2008, the A. O. Smith Special Committee held its initial meeting following a meeting of the A. O. Smith board of directors. At this meeting, the A. O. Smith Special Committee discussed the proposed transaction in general terms and the retention of legal counsel. Mr. Greubel was designated as Chairman of the A. O. Smith Special Committee.

On February 20, 2008, the A. O. Smith Special Committee interviewed potential legal advisors, and at a meeting held on February 24, 2008, selected Winston as its independent legal advisor. The A. O. Smith Special Committee subsequently engaged Abrams & Laster LLP as its Delaware counsel.

On February 26, 2008 a purported class action was filed against SICO, certain SICO officers and directors, and A. O. Smith in the Milwaukee County Circuit Court in the State of Wisconsin, alleging, among other things, that those officers and directors breached their fiduciary duties in connection with the proposed transaction. The complaint further alleges that A. O. Smith and SICO aided and abetted those alleged breaches of fiduciary duties.

On March 5, 2008, the A. O. Smith Special Committee met with Winston to discuss the proposed transaction with SICO. The A. O. Smith Special Committee expressed its belief that SICO should be responsible for any costs A. O. Smith incurs in considering the proposed transaction. At the meeting, Winston also discussed with the members of the A. O. Smith Special Committee their fiduciary duties as members thereof. Winston subsequently contacted Reinhart, on behalf of the A. O. Smith Special Committee, to request that SICO reimburse A. O. Smith for its expenses in connection with the transaction.

On March 13, 2008, after discussion among the SICO Special Committee and Reinhart, as well as SICO’s management, Reinhart contacted Winston on behalf of the SICO Special Committee and indicated that SICO would be willing to reimburse A. O. Smith for its expenses incurred in connection with the transaction up to $250,000.

On March 18, 2008, the A. O. Smith Special Committee met with and interviewed potential financial advisors to the A. O. Smith Special Committee, and at a meeting held on March 21, 2008, the A. O. Smith Special Committee decided to engage Morgan Stanley as its financial advisor with respect to the proposed transaction, subject to the negotiation of satisfactory engagement terms. After a period of negotiation, the A. O. Smith Special Committee entered into an engagement letter with Morgan Stanley on April 14, 2008.

On March 20, 2008, the A. O. Smith Special Committee proposed that SICO fully reimburse A. O. Smith for all of its reasonable expenses in connection with the transaction proposed by SICO. After a period of negotiation, SICO and A. O. Smith entered into a reimbursement agreement on April 11, 2008, whereby SICO agreed to reimburse A. O. Smith for all of its reasonable out-of-pocket fees, costs and expenses incurred in connection with the proposed transaction up to the time of the execution of a definitive agreement (with any reimbursement of expenses after the execution of a definitive agreement to be addressed in the definitive agreement).

On April 3, 2008, the A. O. Smith Special Committee met with Winston and Morgan Stanley to discuss the proposed transaction process. During the meeting, the A. O. Smith Special Committee reviewed and discussed a proposed timeline for the transaction. The A. O. Smith Special Committee also agreed that Mr. Greubel should set up an initial meeting with Bruce M. Smith, in his capacity as an individual stockholder of SICO, to discuss Mr. Smith’s perspective on the proposed transaction. During the meeting, the A. O. Smith Special Committee discussed with Winston and Morgan Stanley the legal, financial and accounting due diligence to be conducted by A. O. Smith on SICO, including the importance of understanding the potential liabilities of SICO and insulating A. O. Smith both structurally and contractually from such liabilities in any transaction.

Also at this meeting, Morgan Stanley discussed potential improvements in deal terms for A. O. Smith that the A. O. Smith Special Committee could pursue when negotiating with the SICO Special Committee the terms of the proposed transaction. The A. O. Smith Special Committee discussed in detail with Morgan Stanley and Winston these proposed transaction terms. The A. O. Smith Special Committee concluded that it would not adopt any formal position or negotiate with SICO at that time. Instead, the A. O. Smith Special Committee concluded that it should determine its negotiating position once additional due diligence had been conducted.

On April 10, 2008, Winston and Morgan Stanley participated in a conference call with Mr. Stern to discuss SICO and the legal due diligence process.

On April 15, 2008, at a meeting of the A. O. Smith board of directors (other than Bruce M. Smith and Mark D. Smith who recused themselves), Mr. Greubel provided a report to the board on the activities of the A. O. Smith Special Committee.

On April 15, 2008, Mr. Greubel, Winston and Morgan Stanley met with Bruce M. Smith and Latham to discuss the proposed transaction. Mr. Smith attended this meeting solely in his capacity as an individual stockholder of SICO to provide background for his views on the proposed transaction.

On April 23, 2008, SICO and the SICO Special Committee requested that the A. O. Smith Special Committee pass resolutions regarding DGCL Section 203 and the proposed transaction.

On April 24, 2008, A. O. Smith and SICO entered into a confidentiality agreement to facilitate A. O. Smith’s due diligence review of SICO. Shortly thereafter, A. O. Smith, in consultation with the advisors to the A. O. Smith Special Committee began conducting a due diligence review of SICO.

On May 5, 2008, as part of the due diligence process, Winston and Morgan Stanley met with Messrs. Jones and Stern and Terry M. Murphy, Executive Vice President and Chief Financial Officer of A. O. Smith, to discuss the perspective of A. O. Smith management on the proposed transaction and A. O. Smith’s business strategy.

On May 8, 2008, the A. O. Smith Special Committee engaged Crowe Chizek and Company LLC, which we refer to as “Crowe Chizek,” to conduct tax and financial due diligence on SICO and its subsidiaries.

Mr. Greubel and advisors to the A. O. Smith Special Committee met with Mr. Barr and advisors to the SICO Special Committee on May 20, 2008. The parties discussed the status of the due diligence review of SICO and the timing of a potential transaction. The parties did not negotiate the terms of any potential transaction at this time.

On May 30, 2008, the A. O. Smith Special Committee held a telephonic meeting to discuss the status of the due diligence process. Winston summarized the status of its legal due diligence review of SICO and Crowe Chizek’s tax and financial due diligence review of SICO. Winston also summarized for the A. O. Smith Special Committee the request by SICO and certain members of the Smith Family regarding the DGCL Section 203 resolutions. The A. O. Smith Special Committee agreed to consider the resolutions at its next meeting. The A. O. Smith Special Committee discussed with Morgan Stanley and Winston the timing for formulating a response to SICO’s proposal. The A. O. Smith Special Committee concluded that it would not respond to the SICO proposal until A. O. Smith had substantially completed its due diligence review of SICO. The A. O. Smith Special Committee instructed Morgan Stanley and Winston to further refine their analysis of potential improvements in deal terms for A. O. Smith discussed at the April 3,^,2008 meeting.

On June 10, 2008, Winston and Morgan Stanley met with Bruce M. Smith and Wesley A. Ulrich, Vice President, Chief Financial Officer, Secretary and Treasurer of SICO, as part of the due diligence process to discuss the business operations of SICO and its subsidiaries.

On June 13, 2008, the A. O. Smith Special Committee held a telephonic meeting to discuss the due diligence status and findings, the DGCL Section 203 resolutions and a proposed response to SICO’s proposal. Winston summarized the status of its legal due diligence review of SICO and gave a brief summary of potential issues that were a focus of the due diligence. The A. O. Smith Special Committee approved the DGCL Section 203 resolutions. The A. O. Smith Special Committee discussed with its advisors potential deal term improvements for A. O. Smith and a proposed response to SICO’s proposal.

On July 14, 2008, at a meeting of the A. O. Smith board of directors (other than Bruce M. Smith and Mark D. Smith, who recused themselves), Mr. Greubel provided a report to the board on the activities of the A. O. Smith Special Committee.

On July 18, 2008, the A. O Smith Special Committee held a telephonic meeting. At the meeting, Winston discussed with the A. O. Smith Special Committee its fiduciary duties in connection with the proposed transaction with SICO. Winston then discussed with the A. O. Smith Special Committee the legal due diligence

review of SICO, which included a detailed explanation of the scope of the due diligence conducted and potential liabilities of SICO and its subsidiaries, including liabilities related to potential litigation and environmental issues. Crowe Chizek also reported its tax and financial due diligence findings to the A. O. Smith Special Committee. Next, Winston and Morgan Stanley discussed with the A. O. Smith Special Committee a proposed response to SICO’s proposal, including the potential improvements for A. O. Smith in deal terms that the A. O. Smith Special Committee could pursue based on the due diligence completed to date. The A. O. Smith Special Committee instructed Morgan Stanley and Winston to finalize the proposed response to SICO, consistent with the discussions at the meeting, which Mr. Greubel would deliver to the SICO Special Committee.

On July 23, 2008, Mr. Greubel, Winston and Morgan Stanley met with the SICO Special Committee and Reinhart in Milwaukee, Wisconsin to present the response of the A. O. Smith Special Committee to the SICO proposal made on February 2, 2008. The response of the A. O. Smith Special Committee included, among other things, that the transaction terms provide for the following:

•

a 5% discount to reduce the exchange ratio in the merger to 0.95 new shares of A. O. Smith Class A common stock and A. O. Smith common stock for each share of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO;

•

an amendment to the A. O. Smith Existing Charter to provide for the automatic conversion to A. O. Smith common stock of any shares of A. O. Smith Class A common stock that are transferred to an unaffiliated third party;

•

an amendment to the A. O. Smith Existing Charter to add a provision for all of the outstanding A. O. Smith Class A common stock to convert automatically to A. O. Smith common stock if the outstanding A. O. Smith Class A common stock represents less than 15% of the total outstanding A. O. Smith Class A common stock and A. O. Smith common stock;

•

an amendment to the A. O. Smith Existing Charter to provide the holders of A. O. Smith common stock with the right to elect one additional member of the A. O. Smith board of directors;

•

a right of first refusal to A. O. Smith if members of the Smith Family propose to transfer 33% or more of their A. O. Smith Class A common stock in a single transaction;

•

a requirement that members of the Smith Family agree for a period of five-years not to enter into agreements or arrangements relating to the shares of A. O. Smith Class A common stock and A. O. Smith common stock to be issued in the merger to such members of the Smith Family without the advance approval of the independent members of the A. O. Smith board of directors;

•

indemnification of A. O. Smith for liabilities related to the historical operation of SICO and any litigation or transaction expenses, with such indemnification to be supported by an escrow of 10% of the new shares of A. O. Smith Class A common stock and A. O. Smith common stock to be issued to SICO’s stockholders in the merger and by personal indemnification from certain members of the Smith Family; and

•

that the merger be approved by a majority of the A. O. Smith Unaffiliated Stockholders, voting separately on the merger.

During the presentation, the parties discussed each issue raised in the A. O. Smith Special Committee’s response. The meeting concluded with Mr. Barr indicating that the SICO Special Committee would need to further review and discuss the A. O. Smith Special Committee’s requests before providing a response.

In the morning of July 24, 2008, Morgan Stanley and Mr. Barr held a conference call to further discuss the A. O. Smith Special Committee’s response to the SICO proposal. Later that day, the A. O. Smith Special Committee met telephonically with representatives of Winston, Morgan Stanley and Abrams & Laster to discuss the previous day’s meeting with the SICO Special Committee.

On August 19, 2008, certain members of the Smith Family filed a Schedule 13D with the SEC to report that they had determined to jointly engage in discussions with other stockholders of SICO, the SICO Special Committee and potentially A. O. Smith and the A. O. Smith Special Committee regarding the proposed transaction. These members of the Smith Family appointed Arthur O. Smith and Bruce M. Smith as their representatives and Quarles as their legal counsel.

During the period from July 24, 2008 through September 3, 2008, Reinhart consulted with the members of the SICO Special Committee regarding the A. O. Smith Special Committee’s July 23, 2008 requests and the terms of a response to the A. O. Smith Special Committee. Reinhart also consulted with Quarles to discuss the position of the representatives of the members of the Smith Family represented by Quarles, particularly with respect to the requests made by the A. O. Smith Special Committee that were directed to the Smith Family.

On September 3, 2008, the SICO Special Committee provided the following response to the A. O. Smith Special Committee’s July 23, 2008 requests:

•

the SICO Special Committee was unwilling to accept a discount in the exchange ratio;

•

the SICO Special Committee was willing to accept an amendment to the A. O. Smith Existing Charter to provide for the automatic conversion to A. O. Smith common stock of any shares of A. O. Smith Class A common stock that are transferred to an unaffiliated third party;

•

the SICO Special Committee was willing to accept an amendment to the A. O. Smith Existing Charter to add a provision for all of the outstanding A. O. Smith Class A common stock to convert automatically to A. O. Smith common stock provided that the threshold was 7% of the total outstanding A. O. Smith Class A common stock and A. O. Smith common stock rather than the 15% requested by the A. O. Smith Special Committee;

•

the SICO Special Committee was willing to accept an amendment to the A. O. Smith Existing Charter to provide the holders of the A. O. Smith common stock with the right to elect one additional member of the A. O. Smith board of directors;

•

representatives of certain members of the Smith Family were unwilling to accept granting a right of first refusal to A. O. Smith if members of the Smith Family propose to transfer 33% or more of their A. O. Smith Class A common stock in a single transaction;

•

representatives of certain members of the Smith Family were unwilling to agree for a period of five-years not to enter into agreements or arrangements relating to shares of A. O. Smith stock to be issued in the merger to members of the Smith Family, but they may be willing to discuss more limited restrictions on arrangements with third parties unrelated to SICO stockholders;

•

the SICO Special Committee was willing to provide for indemnification of A. O. Smith for liabilities related to the historical operation of SICO and any litigation or transaction expenses, with such indemnification to be limited to a two year survival period and a $10 million cap, but with no escrow of shares;

•

representatives of members of the Smith Family holding a majority of the outstanding shares of SICO common stock were unwilling to accept the request for personal indemnification from members of the Smith Family; and

•

the SICO Special Committee believed the requirement that the merger be approved by a majority of the A. O. Smith Unaffiliated Stockholders, voting separately on the merger, was unnecessary.

At a telephonic meeting of the A. O. Smith Special Committee held on September 4, 2008, Winston and Morgan Stanley summarized the response received on September 3, 2008 from the SICO Special Committee. The A. O. Smith Special Committee expressed its general acceptance of the provisions regarding the conversion of A. O. Smith Class A common stock into A. O. Smith common stock upon transfer to unaffiliated third parties

and agreed that it would not continue to insist that certain SICO stockholders grant A. O. Smith a right of first refusal with respect to certain transfers of their shares of A. O. Smith. The A. O. Smith Special Committee and its advisors then discussed the SICO Special Committee’s response that a discount in the exchange ratio was not acceptable. The A. O. Smith Special Committee and its advisors articulated numerous reasons why they believed a discount in the exchange ratio was appropriate and the A. O. Smith Special Committee concluded that it was not willing to recommend a transaction that did not include a discount in the exchange ratio. However, the A. O. Smith Special Committee indicated that it was willing to consider a discount of less than 5%. The A. O. Smith Special Committee also continued to believe that the merger should be approved by a majority of the A. O. Smith Unaffiliated Stockholders, voting separately on the merger.

The A. O. Smith Special Committee also stated that it believed the threshold at which all A. O. Smith Class A common stock should automatically convert into A. O. Smith common stock should be increased from SICO’s proposed 7% of the total outstanding A. O. Smith Class A common stock and A. O. Smith common stock to somewhere in the range of 10% and 12%. Finally, the A. O. Smith Special Committee concluded that it was important to have an escrow of shares to provide a source of recourse for any indemnification claims. The A. O. Smith Special Committee determined that it would not continue to insist upon direct indemnification from certain members of the Smith Family.

On September 15, 2008, the A. O. Smith Special Committee held a telephonic meeting with Winston and Morgan Stanley to discuss a response to the SICO Special Committee. The A. O. Smith Special Committee authorized Winston and Morgan and Stanley to negotiate open transaction issues with the advisors to SICO and the SICO Special Committee consistent with the positions articulated at the September 4th meeting.

The advisors to the A. O. Smith Special Committee, including representatives from Winston, Morgan Stanley and Abrams & Laster, and advisors to SICO and the SICO Special Committee, including representatives from Reinhart and Latham, met at the offices of Winston on October 2, 2008 to discuss the open transaction issues. The parties discussed the exchange ratio discount and Reinhart indicated that the SICO Special Committee would be willing to consider a discount in the exchange ratio of approximately 1%, but not a 5% discount, and that the SICO Special Committee would not be willing to accept a separate vote on the merger by the A. O. Smith Unaffiliated Stockholders. The advisors to the A. O. Smith Special Committee, as authorized by the A. O. Smith Special Committee, responded that a 3% discount would be acceptable to the A. O. Smith Special Committee. However, the advisors to the A. O. Smith Special Committee did not agree to withdraw its request for a separate vote on the merger by the A. O. Smith Unaffiliated Stockholders. Reinhart agreed to take this response to the SICO Special Committee for its review. Latham then conveyed its understanding that certain members of the Smith Family were willing to consider certain restrictions relating to the shares of A. O. Smith Class A common stock and A. O. Smith common stock that they would receive in the merger, and Winston conveyed that the A. O. Smith Special Committee was withdrawing its proposals for members of the Smith Family to be subject to a right of first refusal and to provide personal indemnification for liabilities relating to SICO’s historical operations. After discussing the other remaining issues, the advisors to SICO and the SICO Special Committee agreed to an escrow of shares with a value of $15,000,000 to provide a source of recourse for any indemnification claims, including for any liabilities associated with SICO’s spun-off operating subsidiaries. The advisors to SICO and the SICO Special Committee also agreed that SpinCo would provide indemnification from any such liabilities. The advisors to the A. O. Smith Special Committee agreed that a portion of the A. O. Smith shares would be released from escrow upon the resolution of any transaction litigation. Reinhart informed Winston and Morgan Stanley that the SICO Special Committee was willing to accept a threshold for the automatic conversion of all A. O. Smith Class A common stock of 7.5%.

The A. O. Smith Special Committee held a telephonic meeting on October 7, 2008 to discuss the October 2nd meeting. Morgan Stanley reported that the advisors had made progress on the outstanding issues but they were still unable to reach agreement on a number of key issues, including the exchange ratio discount, the percentage threshold below which all A. O. Smith Class A common stock would convert into A. O Smith common stock and the separate vote on the merger by the A. O. Smith Unaffiliated Stockholders.

On October 8, 2008, the members of the SICO Special Committee participated in a teleconference with Reinhart, Latham and Quarles to review the October 2nd meeting and the status of the outstanding issues. The members of the SICO Special Committee subsequently authorized Reinhart to offer a 1% exchange ratio discount and to continue to request a threshold of 7.5% for the conversion of the A. O. Smith Class A common stock and that the A. O. Smith Special Committee withdraw its request for a separate vote of the A. O. Smith Unaffiliated Stockholders.

On October 13, 2008, at a meeting of the A. O. Smith board of directors (other than Bruce M. Smith and Mark D. Smith who recused themselves), Mr. Greubel provided a report to the board on the activities of the A. O. Smith Special Committee regarding the ongoing negotiations with SICO.

During the next week, the advisors to the A. O. Smith Special Committee and the SICO Special Committee participated in a series of telephone calls regarding the remaining issues. Following these discussions, Winston and Morgan Stanley participated in a telephonic meeting with the A. O. Smith Special Committee on October 15, 2008, to update the A. O. Smith Special Committee on the status of their discussions with the advisors to the SICO Special Committee. Morgan Stanley reported that the SICO Special Committee had offered an exchange ratio discount of 1%, continued to request an A. O. Smith Class A common stock conversion threshold of 7.5% and continued to ask that the A. O. Smith Special Committee withdraw its request for a separate vote of the A. O. Smith Unaffiliated Stockholders. The A. O. Smith Special Committee discussed the terms in detail with its advisors and stressed the importance to A. O. Smith of obtaining a larger exchange ratio discount. The A. O. Smith Special Committee then authorized Winston and Morgan Stanley to contact the advisors to the SICO Special Committee and offer an exchange ratio discount of 2.25% and a conversion threshold of 8%. This offer was conveyed to the SICO Special Committee on October 22, 2008.

On October 22, 2008 and again on October 27, 2008, Reinhart consulted with the members of the SICO Special Committee regarding the A O. Smith Special Committee’s October 22, 2008 offer.

On October 27, 2008, Reinhart called Winston to inform them that the SICO Special Committee was willing to accept an exchange ratio discount of 1.25% provided that A. O. Smith withdraw its request for a separate vote on the merger by a majority of the A. O. Smith Unaffiliated Stockholders. Reinhart also conveyed that the SICO Special Committee was agreeable to an A. O. Smith Class A common stock conversion threshold of 8%. The A. O. Smith Special Committee met telephonically on October 30, 2008 to discuss the status of the negotiations, including the suggested exchange ratio discount of 1.25%. The A. O. Smith Special Committee did not agree to the SICO Special Committee’s offer of a 1.25% exchange ratio discount. However, the A. O. Smith Special Committee authorized Winston to begin negotiating the Merger Agreement and related transaction documents with Reinhart and Latham, in order to assess any other issues that might exist.

The parties held a meeting at the offices of A. O. Smith on November 5, 2008 to discuss a proposed timetable for negotiating the Merger Agreement and related transaction documents. On November 7, 2008, Reinhart distributed a draft of the Merger Agreement and Winston, Latham and Quarles distributed drafts of other transaction documents, including the support agreements, the escrow agreement, the A. O. Smith Amended Charter and the stockholder agreement for certain members of the Smith Family. Between November 7, 2008 and December 8, 2008, the parties negotiated the terms of the definitive agreements for the transaction.

On November 21, 2008, the A. O. Smith Special Committee held a telephonic meeting with Winston and Morgan Stanley to discuss the status of the transaction and the remaining open issues and to review the transaction documents.

On November 26, 2008, Winston distributed drafts of the Merger Agreement and the related transaction documents to the A. O. Smith board of directors.

On December 1, 2008, Winston and Morgan Stanley met with Messrs. Jones, Murphy and Stern in Milwaukee, Wisconsin to discuss their due diligence findings and the status of the negotiations with SICO and the SICO Special Committee.

On December 1, 2008, the SICO Special Committee held a telephonic meeting with Reinhart and Duff & Phelps to discuss the status of the transaction and the remaining open issues.

On December 5, 2008, the SICO Special Committee held a meeting at Reinhart’s offices with its legal and financial advisors. The SICO Special Committee reviewed the open issues in the Merger Agreement and other transaction documents. Reinhart reviewed with the SICO Special Committee its role and authority in connection with the proposed transaction. Duff & Phelps made a presentation regarding its analysis and form of opinion regarding the fairness, from a financial point of view, of the merger consideration to the SICO Unaffiliated Stockholders, assuming an exchange ratio discount of 1.25%, and responded to questions from members of the SICO Special Committee with respect to the information reviewed and the transaction. After the conclusion of the SICO Special Committee meeting, the SICO board of directors held a meeting at Reinhart’s offices to review the terms of the proposed transaction and the Merger Agreement and other transaction documents. Latham also reviewed with the SICO board of directors its fiduciary duties in connection with the transaction, the terms and structure of the proposed transaction and the Merger Agreement and other transaction documents.

On December 5, 2008, representatives from Winston and Reinhart discussed telephonically a possible resolution to the issues of the exchange ratio discount and the separate vote of the A. O. Smith Unaffiliated Stockholders. Winston and Reinhart each agreed to discuss a possible compromise with the respective special committees that in exchange for an exchange ratio discount of 1.5%, the A. O. Smith Special Committee would not require that the merger be approved by a separate vote of the A. O. Smith Unaffiliated Stockholders.

Later that day, the A. O. Smith Special Committee held a telephonic meeting with its legal and financial advisors to discuss and review in detail the negotiated terms of the Merger Agreement and other transaction documents. Winston described to the A. O. Smith Special Committee the suggested compromise on the exchange ratio discount and the separate vote of the A. O. Smith Unaffiliated Stockholders. After discussion the A. O. Smith Special Committee concluded that it was in the best interests of the A. O. Smith Unaffiliated Stockholders to forego a separate vote on the merger by the A. O. Smith Unaffiliated Stockholders in exchange for a 1.5% discount in the exchange ratio.

At this meeting, Morgan Stanley made a presentation regarding its preliminary analysis of the merger and responded to questions from members of the A. O. Smith Special Committee with respect to its presentation. During this discussion Morgan Stanley communicated that, assuming a 1.5% discount in the exchange ratio and the other financial terms of the merger that were discussed by the A. O. Smith Special Committee, Morgan Stanley would expect to be able to deliver an opinion that the exchange ratio was fair from a financial point of view to A. O. Smith.

After considering, among other things, the factors described below under “A. O. Smith’s Reasons for the Merger; Recommendations of the A. O. Smith Special Committee and the A. O. Smith Board of Directors,” and the financial analyses and presentation of Morgan Stanley, the A. O. Smith Special Committee determined that the Merger Agreement, reflecting a 1.5% discount in the exchange ratio, and the other transaction documents are advisable, substantively and procedurally fair to, and in the best interests of A. O. Smith and the A. O. Smith Unaffiliated Stockholders and unanimously recommended that the board of directors of A. O. Smith adopt, authorize and declare advisable the Merger Agreement, the merger and the transactions contemplated thereby.

On December 5, 2008, Winston and Morgan Stanley had a call with Mr. Ulrich and Reinhart to update due diligence regarding the operations of SICO and its subsidiaries since July 2008.

Between December 5, 2008 and December 8, 2008, the advisors to the A. O. Smith Special Committee, the SICO Special Committee and SICO finalized the Merger Agreement and other transaction documents.

On December 8, 2008, Reinhart held a teleconference with Bruce M. Smith and Arthur O. Smith, the representatives of the members of the Smith Family, who collectively own more than 50% of the outstanding shares of SICO common stock, and Quarles. During this call, the representatives confirmed on behalf of these

members of the Smith Family that they would support the proposed transaction with A. O. Smith and that they would not support any alternative transaction that resulted in a sale of SICO or eliminated or limited A. O. Smith’s dual class voting structure.

In the afternoon of December 8, 2008, the A. O. Smith board of directors held a meeting in Milwaukee, Wisconsin. Directors Bruce M. Smith and Mark D. Smith, being members of the Smith Family, recused themselves and did not attend the meeting. Mr. Jones requested that Mr. Greubel, Chairman of the A. O. Smith Special Committee, provide the report of the A. O. Smith Special Committee to the board for its consideration. Mr. Greubel discussed the objectives of the negotiations and the extensive process that the A. O. Smith Special Committee went through. He also provided the A. O. Smith board of directors with a history of the negotiations. Mr. Greubel then discussed the reasons for the transaction from the perspective of A. O. Smith. Mr. Greubel stated that he would provide the recommendation of the A. O. Smith Special Committee after a representative from Winston summarized the proposed transaction and reviewed the agreements with the board.

Winston discussed with the A. O. Smith board of directors the legal standards for the transaction under Delaware law and the fiduciary duties of the directors in considering the proposed transaction. Winston also discussed with the A. O. Smith board of directors the lawsuit that had been filed against SICO and its directors and officers, and A. O. Smith. Winston reviewed in detail the terms of the Merger Agreement and related documents and responded to questions from the directors. Winston also discussed its due diligence findings with the A. O. Smith board of directors and responded to questions about potential liabilities of SICO.

Morgan Stanley next made a presentation regarding its analysis of the transaction and responded to questions from directors with respect to its presentation. Morgan Stanley then subsequently rendered its oral opinion to the A. O. Smith Special Committee and the A. O. Smith board of directors, which opinion subsequently was confirmed in a written opinion dated December 9, 2008, to the effect that as of such date and based upon and subject to the various considerations set forth in the written opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith. Following Morgan Stanley’s presentation, the A. O. Smith board of directors discussed the proposed transaction. Mr. Greubel then reported to the board of directors that the A. O. Smith Special Committee unanimously (a) determined that the Merger Agreement, the ancillary agreements and the transactions contemplated by those agreements, including the merger, are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and the A. O. Smith Unaffiliated Stockholders, (b) recommended that the A. O. Smith board of directors approve and adopt the Merger Agreement, the ancillary agreements and the related transactions, including the merger and (c) recommended that the A. O. Smith Unaffiliated Stockholders approve the Merger Agreement. The A. O. Smith Special Committee then reaffirmed these recommendations. Mr. Jones then requested that the A. O. Smith board of directors consider the proposed transaction and reflect on the presentations, and he adjourned the meeting until the morning of December 9, 2008.

On the morning of December 9, 2008, the A. O. Smith board of directors held a meeting in Milwaukee, Wisconsin. Bruce M. Smith and Mark D. Smith recused themselves and did not attend the portion of the meeting dealing with the SICO proposal. After considering, among other things, the factors described below under “—Reasons for the Merger; Recommendation of the A. O. Smith Special Committee and the A. O. Smith Board of Directors,” the advice of their legal advisor, Winston, the financial analyses and opinion of Morgan Stanley to the A. O. Smith Special Committee and the A. O. Smith board of directors to the effect that as of December 9, 2008 and based upon and subject to the various considerations set forth in its written opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith, and the recommendation of the A. O. Smith Special Committee, the A. O. Smith directors (other than Bruce M. Smith and Mark D. Smith who recused themselves and did not attend the meeting) determined that the Merger Agreement and merger are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and its stockholders (including the A. O. Smith Unaffiliated Stockholders) and adopted resolutions approving the Merger Agreement and the transactions contemplated thereby and recommending that the A. O. Smith stockholders adopt the Merger Agreement, adopt the A. O. Smith Amended Charter and approve the Stock Issuance.

On December 9, 2008, the SICO Special Committee held a meeting by teleconference with representatives of Reinhart and Duff & Phelps attending. Reinhart updated the SICO Special Committee on the proposed resolution of the open issues on the transaction, including the compromise for a discount of 1.5% in the exchange ratio. Representatives from Duff & Phelps made a presentation to the SICO Special Committee to cover the changes from its December 5 presentation, including the effect of the discount of 1.5% in the exchange ratio. At the conclusion of its presentation, Duff & Phelps delivered an oral opinion, confirmed in writing by an opinion dated December 9, 2008, that the consideration to be received by the SICO Unaffiliated Stockholders pursuant to the Merger Agreement, as of the date of the opinion and based upon and subject to the assumptions, limitations, qualifications and factors contained therein, is fair, from a financial point of view, to the SICO Unaffiliated Stockholders. The full text of this written opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with this opinion, is attached as Annex I to this joint proxy statement/prospectus. After further discussion and evaluation of the terms and conditions of the Merger Agreement, and after considering, among other things, the factors described below under “—SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and the SICO Board of Directors,” the SICO Special Committee unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and procedurally and substantively fair to, and in the best interests of, SICO and the SICO Unaffiliated Stockholders, and unanimously recommended that SICO board of directors authorize, adopt and approve the Merger Agreement and the transactions contemplated thereby, including the merger.

Following the meeting of the SICO Special Committee, the SICO board of directors held a meeting on December 9, 2008 by teleconference with representatives of Duff & Phelps, Latham and Reinhart attending. Latham updated the SICO board of directors on the resolution of the open issues on the transaction and corresponding changes to the Merger Agreement. Representatives from Duff & Phelps made a presentation to the SICO board of directors, and responded to questions from members of the SICO board of directors with respect to the information reviewed and the transaction. Duff & Phelps informed the SICO board of directors that it had previously delivered its opinion to the SICO Special Committee and that the members of the SICO board of directors are entitled to rely on that opinion. The SICO Special Committee then reported to the SICO board of directors as to the SICO Special Committee’s recommendation in favor of the Merger Agreement and the transactions contemplated thereby, including the merger. After further discussion and evaluation of the terms and conditions of the Merger Agreement, and after considering, among other things, the factors described below under “—SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and the SICO Board of Directors,” the SICO board of directors unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and procedurally and substantively fair to, and in the best interests of, the stockholders of SICO, and unanimously approved the Merger Agreement and the transactions contemplated thereby, including the merger.

Later in the day on December 9, 2008, A. O. Smith, MergerCo, SICO and SpinCo executed and delivered the Merger Agreement, SICO and A. O. Smith executed a support agreement, and SICO, A. O. Smith and certain members of the Smith Family executed a support agreement. A. O. Smith and certain members of the Smith Family also executed the stockholder agreement. On December 9, 2008, A. O. Smith and SICO issued a joint press release publicly announcing the signing of the Merger Agreement and related transaction documents.

A. O. Smith’s Reasons for the Merger; Recommendations of the A. O. Smith Special Committee and A. O. Smith Board of Directors

The A. O. Smith Special Committee, consisting solely of independent and disinterested directors, and acting with the advice and assistance of its independent financial and legal advisors, evaluated and negotiated the terms of the merger, including the terms and conditions of the Merger Agreement. On December 5, 2008, the A. O. Smith Special Committee unanimously determined that the merger, the terms of the Merger Agreement and the transactions contemplated thereby are advisable and substantively and procedurally fair to, and in the best interests of A. O. Smith and the A. O. Smith Unaffiliated Stockholders, recommended that the A. O. Smith board

of directors adopt, authorize and declare advisable the merger, Merger Agreement and the other transactions contemplated by the Merger Agreement and recommended that the A. O. Smith Unaffiliated Stockholders adopt the Merger Agreement. The A. O. Smith Special Committee reaffirmed its recommendations on December 8, 2008. On December 9, 2008, at a meeting of the A. O. Smith board of directors, after hearing and considering the A. O. Smith Special Committee’s recommendation, the A. O. Smith board of directors (other than Mr. Bruce M. Smith and Mr. Mark D. Smith who recused themselves and did not attend the meeting) determined that the Merger Agreement, the merger and the other transactions contemplated by the Merger Agreement are advisable and substantively and procedurally fair to, and in the best interests of, A. O. Smith and its stockholders (including the A. O. Smith Unaffiliated Stockholders) and approved the Merger Agreement, the merger and the other transactions contemplated by the Merger Agreement.

The A. O. Smith Special Committee recommends that the A. O. Smith Unaffiliated Stockholders vote “FOR” the proposal to adopt the Merger Agreement. The A. O. Smith board of directors recommends that A. O. Smith stockholders vote “FOR” the proposal to adopt the Merger Agreement, “FOR” the proposal to adopt the A. O. Smith Amended Charter and “FOR” the proposal to approve the Stock Issuance.

In the course of reaching their determination, the A. O. Smith Special Committee and the A. O. Smith board of directors considered the following factors and potential benefits of the merger, each of which they believed supported their decision and provided assurance of the substantive fairness of the merger to A. O. Smith’s stockholders (including the A. O. Smith Unaffiliated Stockholders):

•

the fact that the exchange ratio in the Merger Agreement reflects a discount of 1.5%, such that the merger will result in the SICO stockholders receiving, in the aggregate, 98.5% of the total number of shares of each of the A. O. Smith Class A common stock and A. O. Smith common stock held by SICO prior to the effective time of the merger, subject to the treatment of Escrow Shares, fractional shares and dissenting shares described in this joint proxy statement/prospectus;

•

the fact that the value of the shares of A. O. Smith Class A common stock and A. O. Smith common stock reflected in this discount (assuming a one for one conversion of the A. O. Smith Class A common stock into A. O. Smith common stock) was $4.6 million, based on the closing price of $31.81 of the A. O. Smith common stock on the NYSE on December 8, 2008, the last full trading day prior to the execution of the Merger Agreement;

•

the fact that the discount reflected in the exchange ratio is fixed at 1.5% of the total number of A. O. Smith shares held by SICO, such that if the price of A. O. Smith Class A common stock and A. O. Smith common stock increases, the dollar amount of benefit from this discount to the A. O. Smith Unaffiliated Stockholders also increases;

•

the fact that SICO stockholders will have a more efficient tax position, will own A. O. Smith shares directly and can sell the shares as needed, all of which will enable them to act in the interests of the other long-term A. O. Smith stockholders;

•

the fact that the ability of SICO stockholders to sell their A. O. Smith shares could provide greater long-term liquidity for the A. O. Smith common stock since the A. O. Smith Class A common stock will convert into A. O. Smith common stock upon any public sale of A. O. Smith Class A common stock;

•

the fact that amendments to the A. O. Smith Existing Charter contemplated by the transaction reduces substantially the possibility that holders of A. O. Smith Class A common stock could obtain a theoretical control premium on a sale of those shares, and may ultimately result in the elimination of the dual class voting structure at A. O. Smith;

•

the fact that A. O. Smith Class A common stock will automatically convert into A. O. Smith common stock if the total number of outstanding shares of A. O. Smith Class A common stock falls below

2,397,976 shares, which is approximately 8% of the combined outstanding A. O. Smith Class A common stock and A. O. Smith common stock as of the date of the Merger Agreement, which may ultimately prevent holders of shares representing a disproportionately small economic interest in A. O. Smith from controlling A. O. Smith;

•

the fact that holders of A. O. Smith Class A common stock may no longer transfer their stock to non-Smith Family unaffiliated third parties without the shares automatically converting to A. O. Smith common stock, which is expected to disperse voting control to the holders of A. O. Smith common stock over time;

•

the belief that the revised and improved corporate governance structure reaffirms the A. O. Smith board of directors’ commitment to making decisions in the best interests of all stockholders, which is expected to increase the confidence of public stockholders in A. O. Smith;

•

the belief that the revised corporate governance structure allows the Smith Family to continue its long-standing and strong commitment to A. O. Smith and enables A. O. Smith’s management to continue making decisions for the long-term best interests of A. O. Smith and all of its stockholders;

•

the fact that holders of A. O. Smith common stock will be entitled to elect 33-¹/₃% of the members of the A. O. Smith board of directors, which is an increase from their current right to elect 25% of the members;

•

the fact that certain members of the Smith Family will agree to certain restrictions in the stockholder agreement which provide the A. O. Smith board of directors the right to approve certain actions these members of the Smith Family could take or propose to the possible disadvantage of the other stockholders, such as a going-private transaction;

•

the fact that the A. O. Smith Special Committee and its legal and financial advisors conducted arm’s length negotiations with the SICO Special Committee and its legal and financial advisors regarding the terms of the merger, and the belief of the A. O. Smith Special Committee and the A. O. Smith board of directors that the terms of the merger are as favorable to A. O. Smith and the A. O. Smith Unaffiliated Stockholders as could reasonably be attained under the circumstances;

•

the results of business, legal and financial due diligence investigations of SICO and its subsidiaries conducted by A. O. Smith’s management and legal and financial advisors, and the resulting conclusions by the parties conducting the due diligence investigations;

•

the fact that A. O. Smith and its subsidiaries are indemnified by SpinCo and from the escrow, for substantially all liabilities relating to or arising from the operation of SICO’s operating businesses prior to the merger;

•

the fact that A. O. Smith will be reimbursed by SICO for substantially all of its fees and expenses incurred in connection with the transaction;

•

the financial analysis presented by Morgan Stanley, independent financial advisor to the A. O. Smith Special Committee, and its oral opinion, rendered on December 8, 2008, which opinion subsequently was confirmed in a written opinion dated December 9, 2008, to the A. O. Smith Special Committee and the A. O. Smith board of directors, to the effect that as of such date and based upon and subject to the various considerations set forth in the written opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith (see the sections entitled “—Opinion of Morgan Stanley, Financial Advisor to the A. O. Smith Special Committee,” beginning on page 69);

•

the fact that shares of A. O. Smith Class A common stock and A. O. Smith common stock held by SICO representing approximately 78.9% of the voting power of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, and 97.1% of the voting power of the total outstanding shares of A. O. Smith Class A common stock, voting as a separate class, have agreed to vote in favor of the adoption of the Merger Agreement and the transactions contemplated by the Merger Agreement (see “Agreements Relating to the Merger—SICO Support Agreement” beginning on page 105);

•

the fact that shares of SICO common stock representing approximately 52.7% of the voting power of the total outstanding shares of SICO common stock have agreed to vote in favor of the approval of the Merger Agreement (see “Agreements Relating to the Merger—Smith Family Support Agreement” beginning on page 105); and

•

the belief that the terms of the Merger Agreement, including the parties’ respective representations, warranties and covenants, are reasonable.

The A. O. Smith Special Committee and the A. O. Smith board of directors also considered a number of factors relating to the procedural safeguards involved in the negotiation of the merger, including those discussed below, each of which they believed supported their decision and provided assurance of the substantive and procedural fairness of the merger to A. O. Smith’s stockholders (including the A. O. Smith Unaffiliated Stockholders):

•

the fact that A. O. Smith’s board of directors established a special committee of independent and disinterested directors, consisting solely of directors who are not officers, employees or affiliated in any way (other than in their capacities as directors of A. O. Smith) with A. O. Smith, SICO or the Smith Family to review, evaluate and negotiate proposals made by SICO with respect to a potential transaction;

•

the fact that the terms and conditions of the Merger Agreement resulted from extensive negotiations between the A. O. Smith Special Committee and its advisors and the SICO Special Committee, SICO and their respective advisors;

•

the fact that, subject to compliance with the terms and conditions of the Merger Agreement, if there is a material intervening event, the A. O. Smith board of directors is permitted, prior to the adoption of the Merger Agreement by its stockholders, to change its recommendation; and

•

receipt of the written opinion of Morgan Stanley delivered on December 9, 2008 to the A. O. Smith Special Committee and the A. O. Smith board of directors to the effect that as of the date of such opinion and based upon and subject to the various considerations set forth in the written opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith.

In addition to the factors described above, the A. O. Smith Special Committee and the A. O. Smith board of directors identified and considered a variety of risks and potentially negative factors in its deliberations concerning the merger, including:

•

the fact that the discount reflected in the exchange ratio is fixed at 1.5% of the total number of A. O. Smith shares held by SICO, such that if the price of A. O. Smith Class A common stock and A. O. Smith common stock decreases, the dollar amount of benefit from this discount to the A. O. Smith Unaffiliated Stockholders also decreases;

•

the possibility that the merger might not be completed as a result of the failure of one or more conditions to the merger, or that completion of the merger might be unduly delayed or subject to adverse conditions that may be imposed by governmental authorities;

•

the risk that the potential benefits sought in the merger might not be fully realized;

•

the fact that the Smith Family members who enter into the voting trust agreement may have significant influence over the management of A. O. Smith;

•

the fact that A. O. Smith is required to submit the approval of the merger to a vote of its stockholders even if the A. O. Smith board of directors withdraws or modifies its recommendation to vote in favor of the merger;

•

the interests that certain directors of A. O. Smith may have with respect to the merger in addition to their interests as A. O. Smith stockholders generally, as described in the section entitled “—Interests of A. O. Smith Executive Officers and Directors in the Merger” beginning on page 79;

•

the fact that non-SICO holders of A. O. Smith Class A common stock will lose the right they currently have to freely transfer their A. O. Smith Class A common stock without the shares converting to A. O. Smith common stock upon transfer;

•

the fact that non-SICO holders of A. O. Smith Class A common stock will have the right to elect fewer directors than they were able to elect prior to the transaction;

•

the fact that the price of A. O. Smith Class A common stock and A. O. Smith common stock may decline if SICO stockholders sell the shares they receive in the merger;

•

the fact that the approval of the merger will not be submitted to a separate vote of the A. O. Smith Unaffiliated Stockholders;

•

the litigation proceedings filed in the Milwaukee County Circuit Court in the State of Wisconsin in connection with the Merger and related transactions, as described in the section entitled “—Legal Proceedings Regarding the Merger” beginning on page 84;

•

the risk that SpinCo could become unable to satisfy its indemnification obligations under the Merger Agreement;

•

the risk that the escrow fund may be insufficient to satisfy all indemnification claims of A. O. Smith and other indemnified parties; and

•

the various other risks associated with the merger set forth under the section entitled “Risk Factors” beginning on page 29.

After considering these factors, the A. O. Smith Special Committee and the A. O. Smith board of directors concluded that on balance the potential benefits of the merger to A. O. Smith and its stockholders outweighed the potential negative factors. In light of the number and wide variety of factors considered in connection with its evaluation of the transaction, the A. O. Smith Special Committee and the A. O. Smith board of directors did not consider it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weights to the specific factors they considered in reaching their determination. Rather, the A. O. Smith Special Committee and the A. O. Smith board of directors made their recommendations based on the totality of information presented to, and the investigation conducted by or at the direction of, the A. O. Smith Special Committee and the A. O. Smith board of directors. In addition, individual directors may have given different weight to different information and factors. This explanation of A. O. Smith’s reasons for recommending the merger and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Forward-Looking Statements” beginning on page 36.

In considering the recommendation of the A. O. Smith board of directors with respect to the merger, you should be aware that certain members of the A. O. Smith board of directors have certain interests in the merger that are different from, or are in addition to, the interests of A. O. Smith’s stockholders generally and which create conflicts of interest. In addition, certain of the directors of A. O. Smith will receive benefits in connection with the merger that are not available to A. O. Smith stockholders generally. For a more complete description of these interests and benefits, see “—Interests of A. O. Smith Executive Officers and Directors in the Merger” beginning on page 79 of this joint proxy statement/prospectus.

SICO’s Reasons for the Merger; Recommendations of the SICO Special Committee and SICO Board of Directors

On December 9, 2008, the SICO Special Committee unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and procedurally and substantively fair to, and in the best interests of, SICO and the SICO Unaffiliated Stockholders, and recommended that the SICO board of directors authorize, adopt and approve the Merger Agreement and the transactions contemplated thereby, including the merger. The SICO Special Committee unanimously recommends that the SICO Unaffiliated Stockholders vote “FOR” the approval the Merger Agreement at the special meeting of the SICO stockholders.

On December 9, 2008, the SICO board of directors unanimously approved the Merger Agreement and the transactions contemplated thereby, including the merger, and determined that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable and procedurally and substantively fair to, and in the best interests of, SICO and the SICO stockholders, including the SICO Unaffiliated Stockholders. The SICO board of directors unanimously recommends that the SICO stockholders vote “FOR” the approval of the Merger Agreement at the special meeting of the SICO stockholders.

The SICO Special Committee and the SICO board of directors, in reaching their respective recommendations with respect to the Merger Agreement, considered a number of factors, including the material factors discussed in the following paragraphs. In light of the number and wide variety of factors considered in connection with their evaluation of the Merger Agreement and the transactions contemplated thereby, including the Merger, neither the SICO Special Committee nor the SICO board of directors considered it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors it considered in reaching its recommendation. The SICO Special Committee and the SICO board of directors viewed their respective recommendations as being based on the totality of the information presented, and the factors they considered. In addition, individual members of the SICO Special Committee or the SICO board of directors, in making their decisions, may have given different weight to different information and factors. This explanation of SICO’s reasons for the Merger and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “—Forward Looking Statements” beginning on page 36.

In arriving at its determination, the SICO Special Committee consulted with the independent legal and financial advisors to the SICO Special Committee, as well as SICO’s management, legal advisors and other representatives. In arriving at its determination, the SICO board of directors separately consulted with the SICO Special Committee, SICO’s management, legal advisors and other representatives, as well as the independent financial advisor to the SICO Special Committee. In addition, the SICO Special Committee and the SICO board of directors considered the following factors as generally supporting their respective recommendations to approve the Merger Agreement:

•

that the SICO common stock has historically traded at a significant discount to the underlying value of the A. O. Smith shares held by SICO, and direct ownership by the SICO stockholders of A. O. Smith shares should eliminate the discount to the value of the A. O. Smith shares caused by in SICO’s holding company structure and the tax inefficiencies associated therewith and allow the SICO stockholders to realize the underlying value of the A. O. Smith shares held by SICO;

•

that direct ownership by the SICO stockholders of A. O. Smith shares will provide enhanced liquidity for the SICO stockholders due to the greater public float and trading volumes for A. O. Smith shares and its NYSE listing, as compared to the SICO common stock, which is thinly traded on the Pink Sheets;

•

that direct ownership by the SICO stockholders of A. O. Smith shares will permit the SICO stockholders to receive direct payment of the full amount of any dividends paid by A. O. Smith with respect to the A. O. Smith shares;

•

that the likelihood of the merger qualifying as a tax-free reorganization under the Code so as to be non-taxable to the SICO stockholders, and the condition to the obligations of the parties to complete the merger that the IRS Letter Ruling be received;

•

that the amendments to the A. O. Smith Existing Charter contemplated by the Merger Agreement could improve the corporate governance structure of A. O. Smith for the benefit of all the A. O. Smith stockholders, including the SICO stockholders entitled to receive A. O. Smith shares in the merger;

•

with respect to the SICO board of directors, the SICO Special Committee’s determination that the Merger Agreement and the transactions contemplated thereby, including the merger, are advisable, procedurally and substantively fair to, and in the best interests of SICO and the SICO Unaffiliated

Stockholders, and its recommendation that the SICO board of directors approve the Merger Agreement, and the transactions contemplated thereby, including the merger, which the SICO board of directors noted was arrived at by independent and disinterested directors, with assistance of independent financial and legal advisors and following vigorous negotiation of the transaction terms and conditions by the SICO Special Committee and its advisors;

•

that A. O. Smith agreed to pay SICO stockholders for the value of tax benefits, refunds and credits of SICO if and when actually realized by A. O. Smith, as more fully described below under “The Merger Agreement—Payment for Tax Benefit Items” beginning on page 100;

•

the financial analyses presented by Duff & Phelps and discussed with the SICO Special Committee and the SICO board of directors and the related opinion of Duff & Phelps, dated December 9, 2008, and subject to the assumptions and qualifications stated therein, to the effect that the consideration to be received in the merger by the SICO Unaffiliated Stockholders was fair, from a financial point of view, to the SICO Unaffiliated Stockholders, as more fully described below under “—Opinion of the Financial Advisor to the SICO Special Committee”;

•

the support of certain members of the Smith Family for the merger, and the statements made by certain members of the Smith Family to the SICO Special Committee and its advisors that alternative transactions would not be supported by such holders, rendering pursuit of such alternative transactions futile because such members of the Smith Family hold in excess of a majority of the outstanding SICO common stock; and

•

that all SICO stockholders would have the right to dissent from the merger and obtain payment of the fair value of their shares of SICO common stock under Nevada law, as more fully described below under “—Appraisal Rights; Dissenter’s Rights” beginning on page 84.

The SICO board of directors also identified and considered the following factors relating to potential adverse consequences of the proposed transaction to SICO:

•

the aggregate number of A. O. Smith shares to be received by the holders of SICO common stock in the merger reflects a discount of 1.5% to the aggregate number of A. O. Smith shares currently held by SICO;

•

that the fees and expenses of SICO and A. O. Smith associated with the completion of the merger, including that SICO has agreed to reimburse A. O. Smith for substantially all of its fees and expenses incurred in connection with the transaction;

•

that the amendments to the A. O. Smith Existing Charter contemplated by the transaction may, among other things, have a negative impact on the transferability of A. O. Smith Class A common stock, eliminate the ability for holders of A. O. Smith Class A common stock to obtain a theoretical control premium on a sale of those shares, and ultimately result in the elimination of the dual class voting structure at A. O. Smith;

•

that an amendment to the A. O. Smith Existing Charter contemplated by the transaction will result in a reduction in the number of directors elected by the holders of A. O. Smith Class A common stock;

•

that the indemnification obligations to A. O. Smith under the Merger Agreement, and that shares of A. O. Smith common stock that otherwise would be delivered to the holders of SICO common stock in the merger are required to be placed in escrow and may be used as a source of indemnification payments to A. O. Smith;

•

the risk that the merger may not be completed and the potential impact on SICO, including the fact that the Spin-Off has been completed and cannot be undone;

•

the diversion of management focus and resources from other strategic opportunities and from operational matters while working to implement the merger;

•

the interests that certain executive officers and directors of SICO may have with respect to the merger, in addition to their interests as SICO stockholders generally, as described in the section entitled “—Interests of SICO Executive Officers and Directors in the Merger” beginning on page 80;

•

the litigation proceedings filed in the Milwaukee County Circuit Court in the State of Wisconsin in connection with the merger and related transactions, as described in the section entitled “—Legal Proceedings Regarding the Merger” beginning on page 84; and

•

various other applicable risks associated with the merger, including those described under the section entitled “—Risk Factors” beginning on page 29.

The SICO Special Committee and the SICO board of directors weighed the benefits, advantages and opportunities against the risks of entering into the Merger Agreement and completing the merger and the other transactions contemplated by the Merger Agreement. Although the SICO Special Committee and the SICO board of directors realized that there can be no assurance about future results or outcomes, including results expected or considered in the factors listed above, the SICO Special Committee and the SICO board of directors concluded that the potential benefits outweighed the potential risks of completing the merger and the other transactions contemplated by the Merger Agreement.

The foregoing discussion of the material factors considered by the SICO Special Committee and the SICO board of directors is not intended to be exhaustive, but does set forth the principal factors considered by the SICO Special Committee and the SICO board of directors.

In considering the recommendation of SICO’s board of directors with respect to the merger, you should be aware that certain members of SICO’s board of directors and certain SICO officers have interests in the merger that are different from, or are in addition to, the interests of SICO’s stockholders generally and which create conflicts of interest. In addition, certain of the directors and officers of SICO will receive benefits in connection with the merger that are not available to other SICO stockholders. For a more complete description of these interests and benefits, see “—Interests of SICO Executive Officers and Directors in the Merger” beginning on page 80 of this joint proxy statement/prospectus.

Opinion of Morgan Stanley, Financial Advisor to the A. O. Smith Special Committee

The A. O. Smith Special Committee retained Morgan Stanley to provide it with financial advisory services and to provide it and the A. O. Smith board of directors a financial opinion in connection with the proposed merger. The A. O. Smith Special Committee selected Morgan Stanley to act as its financial advisor based on Morgan Stanley’s qualifications, expertise and reputation. On December 8, 2008, Morgan Stanley rendered its oral opinion, which opinion subsequently was confirmed in a written opinion dated December 9, 2008, to the A. O. Smith Special Committee and the A. O. Smith board of directors to the effect that as of such date and based upon and subject to the various considerations set forth in the opinion, the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith.

The full text of the written opinion of Morgan Stanley, dated as of December 9, 2008, is attached to this proxy statement as Annex H. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. We encourage you to read the entire opinion carefully. The opinion, and the other views and analysis of Morgan Stanley referenced throughout this proxy statement, do not constitute a recommendation to any holder of A. O. Smith Class A common stock or A. O. Smith common

stock as to how to vote at the meeting of stockholders to be held in connection with this transaction. In addition, the opinion does not in any manner address the prices at which the A. O. Smith Class A common stock or A. O. Smith common stock will trade following consummation of the merger. Morgan Stanley provided its opinion for the information and assistance of the A. O. Smith Special Committee and the A. O Smith board of directors in connection with the directors’ consideration of the merger, and the opinion addresses only whether the exchange ratio pursuant to the Merger Agreement was fair from a financial point of view to A. O. Smith as of the date of the opinion. The summary of the opinion of Morgan Stanley set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the opinion.

In connection with rendering its opinion, Morgan Stanley, among other things:

•

reviewed certain publicly available financial statements and other business and financial information of A. O. Smith and SICO, respectively;

•

reviewed certain internal historical financial statements and other financial and operating data concerning A. O. Smith and SICO, respectively;

•

discussed the past and current operations and financial condition and the prospects of A. O. Smith with senior executives of A. O. Smith;

•

discussed the past and current operations and financial condition and the prospects of SICO with senior executives of SICO;

•

reviewed the reported prices and trading activity for the A. O. Smith common stock, A. O. Smith Class A common stock and SICO common stock;

•

compared the financial performance of A. O. Smith and the prices and trading activity of A. O. Smith common stock with that of certain other publicly-traded companies comparable with A. O. Smith and its securities;

•

reviewed the financial terms, to the extent publicly available, of certain comparable merger transactions;

•

participated in certain discussions and negotiations among representatives of A. O. Smith and SICO and their financial and legal advisors;

•

reviewed the Merger Agreement and certain related documents; and

•

performed such other analyses and considered such other factors as Morgan Stanley deemed appropriate.

In arriving at its opinion, Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to Morgan Stanley by A. O. Smith and SICO, and formed a substantial basis for the opinion. Morgan Stanley assumed that the Spin-Off and the merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the merger will be treated as a tax-free reorganization and/or exchange, each pursuant to the Code. For the avoidance of doubt, and without limiting the foregoing, Morgan Stanley assumed that A. O. Smith will not assume any tax liability in respect of the Spin-Off. Morgan Stanley assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed Spin-Off and merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed Spin-Off and merger. Morgan Stanley is not a legal, tax or regulatory advisor. Morgan Stanley is a financial advisor only and has relied upon, without independent verification, the assessment of A. O. Smith and SICO and its legal, tax or regulatory advisors with respect to such matters. Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of A. O. Smith or SICO, nor was it furnished with any such appraisals. Morgan Stanley’s

opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to it as of, the date of the opinion. Events occurring after such date may affect the opinion and the assumptions used in preparing it, and Morgan Stanley did not assume any obligation to update, revise or reaffirm the opinion.

The following is a summary of the material analyses performed by Morgan Stanley in connection with its opinion. One of the summaries of financial analysis includes information presented in tabular format. In order to fully understand the financial analysis used by Morgan Stanley, the table must be read together with the text of the summary. The table alone does not constitute a complete description of the financial analysis.

Historical Stock Price Trading Analysis

Morgan Stanley performed a historical stock price trading analysis to provide background and perspective on the historical share price performance of A. O. Smith common stock and SICO common stock prior to and following the public announcement on February 4, 2008 of SICO’s proposal. A. O. Smith announced that it had received SICO’s proposal prior to the open of the United States stock markets on February 4, 2008. The proposal noted, among other terms, that SICO’s stockholders would receive newly issued shares of A. O. Smith Class A common stock and A. O. Smith common stock equal to the A. O. Smith Class A common stock and A. O. Smith common stock shares currently held by SICO. As a result, SICO’s proposal assumed neither a share exchange premium nor discount.

Morgan Stanley noted that A. O. Smith’s common stock share price decreased approximately 2.6% upon announcement of SICO’s proposal, from $36.28, the closing price on Friday, February 1, 2008, to $35.33, the closing price on Monday, February 4, 2008. In contrast, Morgan Stanley noted that the S&P 500 index price had decreased approximately 1.0%, from 1,395.42, the closing price on Friday, February 1, 2008, to 1380.82, the closing price on Monday, February 4, 2008. In addition, Morgan Stanley noted that SICO’s share price increased approximately 49.3% upon announcement of SICO’s proposal, from $63.63, the closing price on Friday, February 1, 2008, to $95.00, the closing price on Monday, February 4, 2008.

Precedent Transactions Analysis

Morgan Stanley also performed a precedent transactions analysis, which attempted to provide a basis for the consideration to be provided in connection with the transaction, in particular with regard to the exchange ratio. Morgan Stanley identified four transactions which in its view were substantially similar in structure and predicated on a comparable motivation to complete the transaction. The following is a list of these transactions:

Selected Precedent Transactions (Parent / Subsidiary)

•

Petrie Stores Corporation / Toys “R” Us, Inc.

•

Seagate Technology, Inc. / VERITAS Software Corporation

•

American BioScience, Inc. / American Pharmaceutical Partners, Inc.

•

Fidelity National Financial, Inc. / Fidelity National Information Services, Inc.

For each transaction listed above, Morgan Stanley analyzed the structure of the transaction to determine their applicability. Morgan Stanley determined that all of the transactions noted above were applicable because they all were mergers of a parent company into a subsidiary in a tax-free exchange of shares. Morgan Stanley reviewed each transaction to determine (i) whether the parent had voting control of the subsidiary through owning shares that provided greater than 50% of the total voting rights of the subsidiary, (ii) whether the parent had economic control of the subsidiary through owning shares that provided greater than 50% of the total ownership of the subsidiary and (iii) the amount, if any, of the discount the parent company received in the exchange of shares. In analyzing the proposed exchange ratio and resultant share exchange discount the SICO

stockholders would receive, Morgan Stanley specifically focused on whether having greater than 50% of the voting control, but less than 50% economic control would cause the parent company to receive a share exchange discount to the subsidiary company shares held by the parent company prior to the merger. The following table provides a summary of the precedent transactions noted above compared to the merger contemplated between SICO and A. O. Smith, including the parent company voting control and economic ownership percentages prior to the merger and the share exchange discount received by the parent.


			Parent % Voting Control / Ownership Prior to Merger				Parent		Share Exchange Discount Received by Parent
Date Completed	Parent	Subsidiary	Voting Control		Economic Ownership		Voting Control	Economic Control	Share Exchange Discount Received by Parent
12/9/1994	Petrie Stores Corporation	Toys “R” Us, Inc.	14	%	14	%	No	No	8	%

11/22/2000	Seagate Technology, Inc.	VERITAS Software Corporation	32	%	32	%	No	No	15	%

4/18/2006	American BioScience, Inc.	American Pharmaceutical Partners, Inc.	66	%	66	%	Yes	Yes	0	%

11/9/2006	Fidelity National Financial, Inc.	Fidelity Information Services	51	%	51	%	Yes	Yes	0	%

TBD	Smith Investment Company	A. O. Smith	79	%	32	%	Yes	No	1.5	%

Morgan Stanley noted that in the Petrie Stores and Seagate Technology transactions, Petrie Stores and Seagate Technology neither had voting nor economic control of Toys “R” Us and VERITAS, respectively, and they received share exchange discounts of approximately 8% and 15%, respectively. Morgan Stanley noted that in the American BioScience and Fidelity National Financial transactions, American BioScience and Fidelity National Financial had both voting and economic control of American Pharmaceutical Partners and Fidelity Information Services, respectively, and did not receive a share exchange discount.

Morgan Stanley noted SICO had voting control, but not economic control of A. O. Smith. In addition, Morgan Stanley noted that pursuant to the Merger Agreement, the SICO stockholders are to receive their pro rata portion of 7,947,690 shares of A. O. Smith Class A common stock and 1,535,801 shares of A. O. Smith common stock, which represents a share exchange discount of 1.5% to the 8,067,252 and 1,559,076 shares of A. O. Smith Class A common stock and A. O. Smith common stock, respectively, currently held by SICO.

In connection with the review of the merger by the A. O Smith Special Committee and the A. O. Smith board of directors, Morgan Stanley performed financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions are beyond the control of A. O. Smith and SICO. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted these analyses described above solely as part of their analysis of the fairness of the exchange ratio pursuant to the Merger Agreement from a financial point of view to A. O. Smith and in connection with the delivery of its opinion to the A. O. Smith Special Committee and the A. O. Smith board of directors. The analyses described above do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold or at which shares of A. O. Smith Class A common stock and A. O. Smith common stock might actually trade. The exchange ratio was determined through arm’s-length negotiations between A. O. Smith and SICO and was approved by the A. O. Smith Special Committee and the A. O. Smith board of directors. Morgan Stanley provided advice to the A. O. Smith Special Committee during these negotiations. Morgan Stanley did not, however, recommend any specific exchange ratio to the A. O. Smith Special Committee or the A. O. Smith board of directors or that any specific exchange ratio constituted the only appropriate exchange ratio for the merger. As described above, Morgan Stanley’s opinion to the A. O. Smith Special Committee and the A. O. Smith board of directors was one of many factors taken into consideration by the A. O. Smith Special Committee and the A. O. Smith board of directors in making their determination to approve the Merger Agreement. The analyses as described above should not be viewed as determinative of the opinion of the A. O. Smith Special Committee and the A. O. Smith board of directors with respect to the exchange ratio or whether the A. O. Smith Special Committee and the A. O. Smith board of directors would have been willing to agree to a different exchange ratio.

Morgan Stanley, as part of its investment banking and financial advisory business, is continuously engaged in performing financial analysis with respect to businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for corporate, estate and other purposes. In the ordinary course of its trading, brokerage, investment management and financing activities, Morgan Stanley or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for their own account or the accounts of customers, in debt or equity securities or loans of A. O. Smith, SICO or any other company or any currency or commodity that may be involved in this transaction. Morgan Stanley’s opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with its customary practice.

Pursuant to a letter agreement, the A. O. Smith Special Committee engaged Morgan Stanley to act as its financial advisor in connection with the contemplated transaction. Pursuant to the terms of the letter agreement, the A. O. Smith Special Committee agreed to pay Morgan Stanley an aggregate fee of $1.75 million. A. O. Smith paid Morgan Stanley a $250,000 fee upon execution of the engagement letter and a $1,250,000 fee upon delivery of Morgan Stanley’s opinion in December 2008. An additional fee of $250,000 will be payable to Morgan Stanley only upon completion of the merger. The A. O. Smith Special Committee has also agreed to reimburse Morgan Stanley for its reasonable expenses, including attorneys’ fees and disbursements. Finally, A. O. Smith has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against various liabilities and expenses, including certain liabilities under the federal securities laws, related to or arising out of the engagement of Morgan Stanley. The terms of the fee arrangement with Morgan Stanley were negotiated at arm’s length between the A. O. Smith Special Committee and Morgan Stanley.

Other than this engagement, during the two years preceding that date of the opinion, Morgan Stanley has not provided any material financial advisory or financing services to any party to the merger for which compensation has been received or is intended to be received.

Opinion of Duff & Phelps, Financial Advisor to the SICO Special Committee

On January 5, 2008, Duff & Phelps was engaged to provide independent financial advisory services to the SICO Special Committee and, as part of the engagement, the SICO Special Committee requested that Duff & Phelps provide an opinion to the SICO Special Committee as to the fairness, from a financial point of view, to

the SICO Unaffiliated Stockholders of the consideration to be received by such holders in the merger. Duff & Phelps was not requested to, and did not in its opinion, address or otherwise provide any opinion with respect to the Spin-Off. The opinion provided by Duff & Phelps was only given with respect to the merger.

On December 9, 2008, Duff & Phelps rendered its oral opinion to the SICO Special Committee, which was subsequently confirmed in a written opinion dated December 9, 2008, that, subject to the limitations, exceptions, assumptions and qualifications set forth therein, as of such date, the consideration to be received by the SICO Unaffiliated Stockholders in the merger was fair from a financial point of view to such holders. The written opinion of Duff & Phelps states that it may also be relied upon by the SICO board of directors. The full text of the written opinion of Duff & Phelps is attached as Annex I to this joint proxy statement/prospectus and is incorporated herein by reference.

The full text of the written opinion should be read carefully in its entirety for a description of the assumptions made, procedures followed, matters considered and qualifications and limitations of the review undertaken in rendering the opinion. The opinion of Duff & Phelps was addressed to the SICO Special Committee and may also be relied upon by the SICO board of directors, but is not intended to, and does not, confer any rights or remedies upon any other person, and is not intended to be used, and may not be used, for any other purpose without Duff & Phelps’ prior written consent, except to the extent specifically permitted by the opinion.

Duff & Phelps has not been requested to, and did not, initiate any discussions with, or solicit any indications of interest from, third parties with respect to the merger, the assets, businesses or operations of SICO, or any alternatives to the merger, or negotiate the terms of the merger. In addition, Duff & Phelps is not expressing any opinion as to the market price or value of the SICO common stock or the A. O. Smith Class A common stock or the A. O. Smith common stock following the public announcement of the merger.

Duff & Phelps’ opinion does not address the merits of the underlying business decision to enter into the merger versus any alternative strategy or transaction, is not a recommendation as to how the SICO Special Committee, the SICO board of directors or any holder of SICO common stock should vote or act with respect to any matters relating to the merger, or whether to proceed with the merger or any related transaction, and does not indicate whether the consideration received is the best possibly attainable under any circumstances.

In connection with its opinion, Duff & Phelps made such reviews, analyses and inquiries as it deemed necessary and appropriate under the circumstances. SICO, the SICO Special Committee and the SICO board of directors placed no limits on the information to which Duff & Phelps had access or the matters it could consider. Duff & Phelps’ due diligence with respect to the merger included, but was not limited to, the following:

•

discussed the merger with the SICO Special Committee and its representatives and SICO and its management and representatives;

•

reviewed certain publicly available business and financial information of SICO and A. O. Smith, respectively;

•

reviewed certain internally prepared financial and operating data concerning SICO, which SICO had identified as being the most current financial statements available;

•

reviewed drafts of the following documents related to the merger: the Merger Agreement and a form of each of the SICO support agreement, the Smith Family support agreement, the A. O. Smith Existing Charter, the A. O. Smith Amended Charter, the escrow agreement, the stockholder agreement and the voting trust agreement;

•

reviewed the historical trading prices and trading volumes of the SICO common stock, A. O. Smith Class A common stock and A. O. Smith common stock; and

•

conducted such other analyses and considered such other factors as Duff & Phelps deemed appropriate.

In performing its analyses and rendering its opinion, Duff & Phelps, with the SICO Special Committee’s consent:

•

assumed that the merger will be treated as a tax-free reorganization for United States Federal income tax purposes;

•

did not address the impact of the merger on any particular SICO stockholder other than in such stockholder’s capacity as a stockholder;

•

relied upon the accuracy, completeness, and fair presentation of all information, data, advice, opinions and representations obtained from public sources or provided to it from private sources, including SICO and its management and representatives and the SICO Special Committee and its representatives, and did not independently verify such information;

•

assumed that the final versions of all documents reviewed by Duff & Phelps in draft form conform in all material respects to the drafts reviewed;

•

assumed that information supplied to Duff & Phelps and representations and warranties made in the Merger Agreement are accurate in all material respects;

•

assumed that all of the conditions required to implement the merger will be satisfied and that the merger will be completed in accordance with the Merger Agreement without any amendments thereto or any waivers of any terms or conditions thereof;

•

relied upon the fact that the SICO Special Committee and SICO have engaged such tax, accounting and legal advisors as they have deemed necessary, and is giving no opinion with respect to any tax, accounting or legal matters;

•

assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect (including any delay, limitation, condition or restriction) on SICO, A. O. Smith or the contemplated benefits expected to be derived in the merger;

•

assumed that each member or descendant of the Smith Family and each trust for the benefit of members or descendants of the Smith Family that is, was or will be required by applicable law or regulation to be a signatory to the Schedule 13D (as defined in the Merger Agreement) has signed or will sign such Schedule 13D;

•

has not taken into account the effect, positive or negative, that any tax attribute of SICO being assumed (including by operation of law) by or transferred to A. O. Smith in the merger would have on the merger; and

•

assumed, based on the direction of the SICO Special Committee, that any alternative to the merger involving a sale of SICO to a third party or a recapitalization of A. O. Smith to eliminate its dual class equity structure would be futile and therefore not available.

In its analysis and in connection with the preparation of its opinion, Duff & Phelps made numerous assumptions with respect to industry performance, general business, market and economic conditions and other matters, many of which are beyond the control of any party involved in the merger. To the extent that any of the foregoing assumptions insofar as they affect the merger or any of the facts on which the Duff & Phelps opinion was based prove to be untrue in any material respect, Duff & Phelps has advised the SICO Special Committee that the Duff & Phelps opinion cannot and should not be relied upon.

Duff & Phelps did not make any independent evaluation of SICO’s, SpinCo’s or A. O. Smith’s solvency or any appraisal or physical inspection of any specific assets or liabilities (contingent or otherwise), nor has Duff & Phelps been furnished with any such evaluations or appraisals. Duff & Phelps is not a legal, tax, accounting or regulatory advisor and has relied upon, without independent verification, the assessment of SICO and its legal,

tax, accounting and regulatory advisors with respect to such matters, and Duff & Phelps has made no assessment as to the impact or timing implications, if any, of any ongoing legal or regulatory investigations. Duff & Phelps has undertaken no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which SICO is or may be a party or is or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which SICO is or may be a party or is or may be subject and, at the SICO Special Committee’s direction and with the SICO Special Committee’s consent, Duff & Phelps’ opinion makes no assumption concerning, and therefore does not consider, the potential effects of such litigation, claims or investigations or possible assertions of claims, outcomes or damages arising out of any such matters. The opinion should not be construed as a valuation opinion, credit rating, solvency opinion, analyses of SICO’s, SpinCo’s or A. O. Smith’s credit worthiness, tax advice, or accounting advice.

Set forth below is a summary of the material financial analyses performed by Duff & Phelps in reaching its fairness conclusions as of December 9, 2008. Although Duff & Phelps reviewed a number of other transactions in connection with the merger, Duff & Phelps did not identify any transaction it believed was comparable to the merger, and, accordingly, in rendering its opinion, Duff & Phelps has relied solely on an analysis designed specifically for the merger. Although developments following the date of the Duff & Phelps opinion may affect the opinion, Duff & Phelps assumed no obligation to update, revise, or reaffirm its opinion. The Duff & Phelps opinion is necessarily based upon market, economic and other conditions that were in effect on, and information made available to Duff & Phelps as of, the date of the opinion. You should understand that developments subsequent to December 9, 2008 may affect the conclusion expressed in the Duff & Phelps opinion, and that Duff & Phelps disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting its opinion. The Duff & Phelps opinion is limited to the fairness as of December 9, 2008, from a financial point of view, to SICO Unaffiliated Stockholders of the consideration to be received by such holders in the merger.

The Duff & Phelps opinion was based on the totality of the various analyses that it performed, and no particular portion of the analysis has any merit standing alone. This summary is qualified in its entirety by reference to the full text of the opinion, attached as Annex I to this joint proxy statement/prospectus. While this summary describes the analysis and factors that Duff & Phelps deemed material in its presentation to the SICO Special Committee, it is not a comprehensive description of all analyses and factors considered by Duff & Phelps. The preparation of a fairness opinion is a complex process that involves various determinations as to the most appropriate and relevant methods of financial analysis and the application of these methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or a summary description. In arriving at its opinion, Duff & Phelps did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Duff & Phelps believes that its analyses must be considered as a whole and that selecting portions of its analyses and of the factors considered by it, without considering all analyses and factors, could create a misleading or incomplete view of the evaluation process underlying its opinion. The conclusion reached by Duff & Phelps was based on all analyses and factors taken, as a whole, and also on the application of Duff & Phelps’ own experience and judgment. This conclusion involved significant elements of subjective judgment and qualitative analysis. Duff & Phelps gives no opinion as to the value or merit standing alone of any one or more parts of the analyses it performed.

Historical Trading Analysis

Duff & Phelps reviewed the historical trading ranges of SICO common stock and A. O. Smith common stock, and the aggregate discount implied by the market capitalization of SICO and the aggregate market value of SICO’s holdings of A. O. Smith shares (assuming one for one conversion of A. O. Smith Class A common stock into A. O. Smith common stock), for various periods before and after February 4, 2008, the date of the public announcement of SICO’s merger proposal to A. O. Smith, to provide Duff & Phelps with background and perspective for how shares of SICO common stock and A. O. Smith common stock have historically traded on a

standalone basis and relative to each other. Duff & Phelps noted that the per share price of SICO common stock includes the value of other assets and liabilities held by SICO, including those related to Berlin Industries and Central States.

Duff & Phelps noted that for the five-year period prior to February 4, 2008, the aggregate discount ranged between a low of $68.4 million and a high of $273.4 million. Duff & Phelps also noted that for the period February 4, 2008 to December 8, 2008, the aggregate discount ranged between a low of negative $8.0 million and high of $140.6 million. Duff & Phelps noted that on January 31, 2008, the last trading day on which the SICO common stock traded prior to the February 4, 2008 public announcement of SICO’s merger proposal to A. O. Smith, the value of a share of SICO common stock was $64.00. Duff & Phelps also noted that on February 1, 2008, the last trading day on which A. O. Smith common stock traded prior to the February 4, 2008 public announcement of SICO’s merger proposal to A. O. Smith, the value of a share of A. O. Smith common stock was $36.28. The trading values for SICO common stock on January 31, 2008 and A. O. Smith common stock on February 1, 2008 imply an aggregate discount of $136.9 million.

SICO Stockholder Benefit Analysis

In addition to analyzing the aggregate discount, Duff & Phelps compared the aggregate discount immediately prior to the February 4, 2008 public announcement of SICO’s merger proposal to A. O. Smith with the estimated costs related to the merger (the “Net Benefit”). Duff & Phelps noted that the Net Benefit only considers the value of SICO’s holdings of A. O. Smith Class A common stock and A. O. Smith common stock, and does not consider SICO’s other assets and liabilities, including Berlin Industries, Central States and tax attributes arising out of the Spin-Off.

Duff & Phelps noted that on January 31, 2008, the last trading day on which the SICO common stock traded prior to the February 4, 2008 public announcement of SICO’s merger proposal to A. O. Smith, the value of a share of SICO common stock was $64.00. Duff & Phelps also noted that on February 1, 2008, the last trading day on which A. O. Smith common stock traded prior to the February 4, 2008 public announcement of SICO’s merger proposal to A. O. Smith, the value of a share of A. O. Smith common stock was $36.28. The trading values for the SICO common stock on January 31, 2008 and A. O. Smith common stock on February 1, 2008 imply a benefit to the SICO stockholders of $136.9 million, prior to consideration of costs related to the merger. The costs related to the merger include costs of the exchange ratio discount and cumulative transaction expenses (both those already incurred by the SICO and by A. O. Smith and those estimated to be incurred by SICO and by A. O. Smith) in excess of $200,000 related to the merger. Based on an exchange ratio discount of 1.5%, the estimated cost of this discount was $5.2 million. Based on an estimate provided by SICO’s management, cumulative transaction expenses in excess of $200,000 were estimated to be approximately $6.6 million. After considering the benefits to the SICO stockholders and the costs related to the merger, the Net Benefit prior to February 4, 2008 is estimated at $125.1 million ($136.9 million – $5.2 million – $6.6 million).

Net Valuation Difference Subsequent to February 4, 2008 Announcement

In addition to the above analyses, Duff & Phelps calculated the estimated net valuation difference as the value of SICO’s holdings of A. O. Smith common stock, less the market capitalization of SICO and costs to effect the merger, including the exchange ratio discount of 1.5% and cumulative transaction expenses in excess of $200,000. Duff & Phelps noted that the net valuation difference only considers the value of SICO’s holdings of A. O. Smith Class A common stock and A. O. Smith common stock, and does not consider SICO’s other assets and liabilities, including Berlin Industries, Central States and tax attributes arising out of the Spin-Off.

As of December 8, 2008, Duff & Phelps noted that the value of a share of SICO common stock was $60.00 and the value of a share of A. O. Smith common stock was $31.91. Based on the December 8, 2008 trading values, the valuation difference before consideration of expenses related to the merger was $107.2 million. After consideration of exchange ratio discount expense of $4.6 million and estimated transaction expenses in excess of $200,000 of $6.6 million, the implied net valuation difference as of December 8, 2008 was $96.0 million ($107.2 million – $4.6 million – $6.6 million).

Miscellaneous

Based on the foregoing analysis, Duff & Phelps concluded that the consideration to be received by the SICO Unaffiliated Stockholders in the merger was fair, from of a financial point of view, to such holders as of the date of its fairness opinion.

In its review and analysis, and in arriving at its opinion, Duff & Phelps assumed and relied upon the accuracy and completeness of all the financial and other information provided to it or publicly available and neither attempted independently to verify, nor assumed responsibility for verifying, any of such information.

The material analyses performed by Duff & Phelps have been summarized above. Nonetheless, the summary set forth above does not purport to be a complete description of the analyses performed by Duff & Phelps. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial analysis and the application of these methods to the particular circumstances. Therefore, such an opinion is not readily susceptible to a summary description. Duff & Phelps did not form a conclusion as to whether any individual analysis, considered in isolation, supported or failed to support an opinion as to fairness. Rather, in reaching its conclusion, Duff & Phelps considered the results of the analyses in light of each other and ultimately reached its opinion based on the results of all analyses taken as a whole. Duff & Phelps did not place a particular reliance or weight on any particular analysis, but instead concluded that its analyses, taken as whole, supported its determination.

The SICO Special Committee selected Duff & Phelps because Duff & Phelps is a leading independent financial advisory firm, offering a broad range of valuation and investment banking services, including fairness and solvency opinions, mergers and acquisitions advisory services, mergers and acquisitions due diligence services, financial reporting and tax valuation, fixed asset and real estate consulting, ESOP and ERISA advisory services, legal business solutions and dispute consulting. Duff & Phelps is regularly engaged in the valuation of businesses and securities in the preparation of fairness opinions in connection with mergers, acquisitions and other strategic transactions.

Fees and Expenses

SICO’s engagement letter with Duff & Phelps provides that, for its services, Duff & Phelps is entitled to receive $400,000 due and payable as follows: $200,000 in cash upon execution of the engagement letter to serve as financial advisor to the SICO Special Committee in its review of possible alternative transactions for SICO; and the remaining $200,000 in cash upon the SICO Special Committee’s request to Duff & Phelps to issue its opinion. No portion of Duff & Phelps’ fee is contingent upon either the conclusion expressed in the opinion or whether the merger is successfully consummated. Furthermore, Duff & Phelps is entitled to be paid additional fees at Duff & Phelps’ standard hourly rates for any time incurred reviewing or assisting in the preparation of any proxy materials or other SEC filings or documents associated with the merger. SICO has also agreed to reimburse Duff & Phelps for its out-of-pocket expenses and reasonable fees and expenses of counsel, consultants, and advisors retained by Duff & Phelps, incurred in connection with the engagement, and to indemnify and hold harmless Duff & Phelps and its affiliates and any other person, director, employee or agent of Duff & Phelps or any of its affiliates, or any person controlling Duff & Phelps or its affiliates, for certain losses, claims, damages, expenses and liabilities relating to or arising out of services provided by Duff & Phelps as financial advisor to the SICO Special Committee. The terms of the fee arrangement with Duff & Phelps, which the SICO Special Committee and Duff & Phelps believe are customary in transactions of this nature, were negotiated at arm’s length between the SICO Special Committee and Duff & Phelps.

Other than this engagement, during the two years preceding the date of the opinion, Duff & Phelps has not had any material relationship with any party to the merger for which compensation has been received or is intended to be received.

Interests of A. O. Smith Executive Officers and Directors in the Merger

A. O. Smith stockholders considering the recommendation of A. O. Smith’s board of directors regarding the merger should be aware that certain directors of A. O.

MergerCo will continue to be a wholly-owned subsidiary of A. O. Smith upon completion of the merger. As a member managed limited liability company, MergerCo will not have a board of managers. Instead, MergerCo will be managed by A. O. Smith, as its sole member. Therefore, following the merger, the directors of A. O. Smith, as discussed immediately above in the section “—A. O. Smith Board of Directors after Completion of the Merger,” will have the power to direct decisions made by A. O. Smith, the managing member of MergerCo.

Legal Proceedings Regarding the Merger

On February 26, 2008, a purported class action complaint was filed in the Milwaukee County Circuit Court in the State of Wisconsin against SICO, certain members of the SICO board of directors, certain officers of SICO and A. O. Smith (collectively, the “Defendants”). The complaint alleges a putative class action consisting of the plaintiff and other SICO stockholders not including the individual named defendants and their immediate families. The complaint claims, among other things, that SICO, certain directors and officers of SICO and A. O. Smith “orchestrated the restructuring without due consideration or regard for the fiduciary duties owed to Plaintiff” and that the individual SICO directors and officers breached their fiduciary duties by self dealing. The lawsuit seeks an injunction requiring the Defendants to provide all documents relevant to the terms and conditions of the proposed transaction and permitting the plaintiff to participate in all negotiations of the terms and conditions of the merger on behalf of the purported class of SICO stockholders. The lawsuit also seeks payment for all fees, costs and expenses incurred during the course of the litigation.

On April 28, 2008, the parties stipulated that the litigation would be stayed until after SICO’s public announcement of the signing of a merger agreement with A. O. Smith and SICO’s dissemination of this definitive proxy statement with respect to a meeting of the SICO stockholders to consider the merger.

The Defendants believe that the plaintiff’s claims are unsupported by the law or facts. The Defendants intend to defend themselves vigorously against these allegations. Because this case is in an early stage, however, an outcome cannot be predicted at this time, and there are no assurances that the action will not prevent or delay the consummation of the merger and/or result in substantial costs. See “Risk Factors” beginning on page 29.

Appraisal Rights; Dissenter’s Rights

A. O. Smith Stockholders

Under the General Corporation Law of the State of Delaware, A. O. Smith stockholders do not have appraisal rights in connection with the merger.

SICO Stockholders

Under NRS Chapter 92A, SICO stockholders will have dissenter’s rights in connection with the merger. In general, shares of SICO common stock issued and outstanding immediately prior to the effective time of the merger that are held by a holder who (a) has not voted such shares in favor of the approval of the Merger Agreement, (b) is entitled to, and who has, properly demanded and perfected dissenter’s rights for such shares of SICO common stock in accordance with NRS 92A.420, and (c) has not effectively withdrawn or forfeited such dissenter’s rights prior to the effective time of the merger, will not be converted into a right to receive Merger Consideration at the effective time of the merger. SICO stockholders who properly demand and perfect their dissenter’s rights are entitled to obtain payment of the fair value of their shares immediately before the effective time of the merger, excluding any appreciation or depreciation in anticipation of the merger.

The following discussion is not a complete statement of the law pertaining to dissenter’s rights under the NRS, and is qualified in its entirety by the full text of NRS 92A.300 to 92A.500, inclusive, as it exists as of the date of this joint proxy statement/prospectus, which provisions are provided in their entirety as Annex J to this joint proxy statement/prospectus. A person having a beneficial interest in shares of capital stock held of record in the name of another person, such as a broker or nominee, who seeks to elect dissenter’s rights must act promptly to cause the record holder to act in accordance with the steps summarized below properly and in a timely manner to prevent such record holder from acting in a manner that may result in a loss of such person’s dissenter’s rights.

Under NRS 92A.410(1), when a proposed merger is to be submitted for approval at a meeting of stockholders of a corporation, as in the case of the SICO special meeting contemplated hereby, the subject corporation must notify each of its stockholders entitled to dissenter’s rights that dissenter’s rights are applicable

and include in that notice a copy of NRS 92A.300 to 92A.500 as it then exists. This joint proxy statement/prospectus constitutes such notice to the holders of SICO common stock, and the applicable statutory provisions of the NRS are attached as Annex J to this joint proxy statement/prospectus. Any SICO stockholder who wishes to assert dissenter’s rights should review carefully the following discussion and Annex J to this joint proxy statement/prospectus. Moreover, because of the complexity of the procedures for asserting dissenter’s rights in respect of SICO common stock, we believe that the SICO stockholders who are considering asserting such dissenter’s rights should seek the advice of counsel, which counsel will not be compensated by us. The failure by a SICO stockholder to comply with the procedures specified in NRS 92A.300 to 92A.500 in a timely and proper manner may result in the loss of such stockholder’s dissenter’s rights, and such stockholder instead will receive payment of the Merger Consideration contemplated by the Merger Agreement on the same basis as other SICO stockholders.

Filing Written Objection

Any SICO stockholder who wishes to assert dissenter’s rights under NRS 92A.300 to 92A.500 must satisfy each of the following conditions:

•

as more fully described below, before the vote on the approval of the Merger Agreement at the SICO special meeting, the stockholder must deliver to SICO at Smith Investment Company, 11270 West Park Place, Milwaukee, Wisconsin, 53224-9508, Attention Corporate Secretary, written notice of the holder’s intent to demand payment for the holder’s shares if the merger is completed; and

•

the stockholder must either not vote on the approval of the Merger Agreement, or must vote his or her shares “AGAINST” the approval of the Merger Agreement either by proxy or in person pursuant to Section 92A.420 of the NRS. A vote “FOR” the approval of the Merger Agreement will constitute a waiver of a stockholder’s dissenter’s rights.

The written notice to SICO of the stockholder’s intent to demand payment for the stockholder’s shares must be in addition to and separate from any proxy or vote. Neither voting (in person or by proxy) against, abstaining from voting, nor failing to vote on the approval of the Merger Agreement will constitute a written notice of intent to demand payment within the meaning of NRS 92A.420.

Notice by MergerCo

Within 10 days after the merger is completed, MergerCo, as the entity surviving the merger, must send a written dissenter’s notice to all SICO stockholders entitled to assert dissenters’ rights.

The dissenter’s notice will specify where stockholders should send their demand for payment, and where and when stockholders must deposit their stock certificates, if any. The dissenter’s notice will also inform stockholders of shares not represented by stock certificates of the extent to which the transfer of their shares will be restricted after their demand for payment is received. The dissenter’s notice will also include a form for demanding payment that references the date the merger was first publicly announced. The stockholder asserting dissenter’s rights must certify on this form whether or not the stockholder acquired beneficial ownership of the shares before the date the merger was first publicly announced. The dissenter’s notice will also set a date by when MergerCo must receive the demand for payment, which may not be less than 30 days nor more than 60 days after the date the dissenter’s notice is delivered. Along with the dissenter’s notice, MergerCo will provide stockholders a copy of NRS 92A.300 through 92A.500.

If, after receiving a dissenter’s notice, the stockholder wishes to assert dissenter’s rights, the stockholder must timely demand payment, certify whether the stockholder acquired beneficial ownership of the shares before the date set forth in the dissenter’s notice, and deposit the stockholder’s certificates, if any, in accordance with the terms of the dissenter’s notice. The failure by the stockholder to demand payment timely and properly or failure to deposit certificates as described in the dissenter’s notice may terminate the stockholder’s right to receive payment pursuant to NRS Chapter 92A.

A stockholder who demands payment and deposits his, her or its certificates, if any, before the effective time of the merger, retains all other rights of a stockholder until those rights are cancelled or modified by the consummation of the merger.

Payment for Shares

Except as described below, within 30 days after the stockholder’s properly executed demand for payment is received by MergerCo, the stockholder will receive what MergerCo has estimated to be the fair value of the stockholder’s shares of SICO common stock, plus accrued interest. The payment will be accompanied by SICO’s balance sheet as of the end of a fiscal year not more than 16 months before the date of payment, an income statement for that year, a statement of changes in the stockholders’ equity for that year, and the latest available interim financial statements, if any. MergerCo will also include an explanation of how it estimated the fair value of the shares and how the accrued interest was calculated, along with information regarding the stockholder’s right to challenge the fair value determined by MergerCo and a copy of NRS 92A.300 to 92A.500.

MergerCo may elect to withhold payment from a dissenting stockholder that became the beneficial owner of the shares on or after the date of the first public announcement of the merger as stated in the dissenter’s notice. To the extent MergerCo withholds payment, after the merger, MergerCo will estimate the fair value of the shares, plus accrued interest, and offer to pay this amount to the stockholder as full satisfaction of the stockholder’s demand of payment. The offer will contain a statement of MergerCo’s estimation of the fair value for shares of SICO’s common stock, an explanation of how the accrued interest was calculated, and a statement of dissenter’s right to demand payment under NRS 92A.480.

Determination of Fair Value

If the dissenting stockholder believes that the consideration paid in exchange for the stockholder’s shares is less than their fair value, or that the interest is not correctly determined, the stockholder may demand an additional payment of the difference between the stockholder’s estimate and MergerCo’s estimate of the fair value per SICO share. The stockholder must make such demand in writing and within 30 days after MergerCo has made or offered payment for the stockholder’s shares.

If a demand for payment remains unsettled, MergerCo, within 60 days after MergerCo receives the stockholder’s demand, will petition the district court of the appropriate county within Nevada to determine the fair value of the shares of SICO common stock and the accrued interest. If MergerCo does not commence such legal proceeding within the 60-day period, MergerCo will be required to pay each dissenting stockholder whose demand remains unsettled the amount demanded.

All dissenters whose demands remain unsettled will be made parties to the proceeding, and are entitled to a judgment for either (a) the amount, if any, by which the court finds the fair value of the stockholder’s shares, plus interest, exceeds the amount paid by MergerCo; or (b) the fair value, plus accrued interest, of the stockholder’s after-acquired shares for which MergerCo withheld payment, plus accrued interest, pursuant to NRS 92A.470.

MergerCo will be required to pay the costs and expenses of the court proceeding unless the court finds the dissenters acted arbitrarily, vexatiously, or not in good faith, in which case the costs will be equitably distributed as and against MergerCo and the dissenters and not necessarily in equal manner. Attorneys’ fees will be divided as the court considers equitable.

SICO stockholders should be aware that the fair value of their shares as determined in a legal proceeding in accordance with NRS 92A.490 could be more than, the same as or less than the Merger Consideration the stockholder would receive under the Merger Agreement.

Any SICO stockholder wishing to exercise dissenter’s rights is urged to consult legal counsel before attempting to exercise dissenter’s rights. The failure of a SICO stockholder to comply strictly with all of the procedures set forth in NRS 92A.300 to 92A.500, inclusive, may result in the loss of such stockholder’s statutory dissenter’s rights.

THE MERGER AGREEMENT

The following summary describes the material terms of the Merger Agreement. The provisions of the Merger Agreement are complicated and not easily summarized. This summary may not contain all of the information about the Merger Agreement that is important to you. The Merger Agreement is attached as Annex A to this joint proxy statement/prospectus and is incorporated by reference in this joint proxy statement/prospectus, and A. O. Smith and SICO encourage you to read it carefully in its entirety for a more complete understanding of the Merger Agreement.

The Merger Agreement has been included to provide you with information regarding its terms. It is not intended to provide any other factual information about A. O. Smith or SICO. Such information can be found elsewhere in this document and in the public filings that A. O. Smith makes with the SEC, which are available without charge through the SEC’s website at http://www.sec.gov.

The representations and warranties described below and included in the Merger Agreement were made by each of A. O. Smith and SICO to the other. These representations and warranties were made as of specific dates and are subject to important exceptions, limitations and supplemental information contained in the confidential disclosure schedules provided by each of A. O. Smith and SICO to the other in connection with the signing of the Merger Agreement. In addition, the representations and warranties may have been included in the Merger Agreement for the purpose of allocating risk between A. O. Smith and SICO rather than to establish matters as facts. The Merger Agreement is described in this joint proxy statement/prospectus and included as Annex A only to provide you with information regarding its terms and conditions, and not to provide any other factual information regarding A. O. Smith, SICO or their respective businesses. Accordingly, you should not rely on the representations and warranties in the Merger Agreement as characterizations of the actual state of facts about A. O. Smith or SICO, and you should read the information provided elsewhere in this joint proxy statement/prospectus and in the documents incorporated by reference in this joint proxy statement/prospectus for information regarding A. O. Smith and SICO and their respective businesses. See “Where You Can Find More Information” beginning on page 138 of this joint proxy statement/prospectus.

The Merger

Each of the A. O. Smith board of directors, the SICO board of directors and the sole member of MergerCo has approved the Merger Agreement, which provides for the merger of SICO with and into MergerCo, with MergerCo surviving the merger as a wholly-owned subsidiary of A. O. Smith.

Effective Time

A. O. Smith and SICO will complete the merger when all of the conditions to completion of the merger contained in the Merger Agreement, which are described in the Section entitled “—Conditions to Obligations to Complete the Merger” beginning on page 96, are satisfied or waived, including the A. O. Smith stockholders’ adoption of the Merger Agreement, adoption of the A. O. Smith Amended Charter and approval of the Stock Issuance and the approval by the SICO stockholders of the Merger Agreement. The merger will become effective upon the filing of articles of merger with the Secretary of the State of the State of Nevada and a certificate of merger with the Secretary of State of the State of Delaware.

Consideration to be Received in the Merger

Upon completion of the merger, each share of SICO common stock outstanding immediately prior to the effective time of the merger will be canceled and automatically converted into the right to receive consideration in the merger, as described below in “—A. O. Smith Class A Common Stock,” “—A. O. Smith Common Stock,” “—A. O. Smith Common Stock in Escrow,” and the cash payable in lieu of any fractional shares, as described below in “—Fractional Shares” beginning on page 89, (collectively, the “Merger Consideration”).

Thereafter, each SICO stock certificate will represent only the right to receive the Merger Consideration. Each share of SICO common stock held or owned by SICO, A. O. Smith, MergerCo or any of their direct or indirect wholly owned subsidiaries immediately prior to the effective time of the merger will be automatically canceled and retired and cease to exist, and none of SICO, A. O. Smith or any of their direct or indirect subsidiaries will receive any securities of SICO or other consideration in exchange for those shares.

SICO has agreed that it will not, without the approval of the board of directors of A. O. Smith, issue new shares of SICO common stock, complete any stock splits with respect to the outstanding shares of SICO common stock or repurchase any shares of SICO common stock. As a result, we do not expect the number of outstanding shares of SICO common stock to change prior to the effective time of the merger. SICO also has agreed that it will not, without the approval of the A. O. Smith board of directors, acquire shares of A. O. Smith Class A common stock or A. O. Smith common stock or sell any of the shares of A. O. Smith Class A common stock or A. O. Smith common stock that it currently holds. In addition, A. O. Smith, currently does not intend to complete any stock splits, declare any stock dividends or take any other corporate action that would result in a change in the number of shares of A. O. Smith Class A common stock or A. O. Smith common stock held by SICO. As a result, we do not expect the number of outstanding shares of A. O. Smith Class A common stock or A. O. Smith common stock held by SICO to change prior to the effective time of the merger.

A. O. Smith Class A Common Stock

Each share of SICO common stock outstanding immediately prior to the effective time of the merger will be converted into the right to receive the number of shares of A. O. Smith Class A common stock equal to (a) 0.9850 multiplied by the number of shares of A. O. Smith Class A common stock held by SICO immediately prior to the effective time of the merger divided by (b) the number of outstanding shares of SICO common stock, rounding to the nearest one one-thousandth (.001) of a share (rounding upward in the case of any .0005 of a share), issued and outstanding immediately prior to the effective time of the merger (excluding dissenting shares) (the “Class A Exchange Ratio”).

For example, assuming there are no dissenting shares, if you currently own 1,000 shares of SICO common stock, absent the treatment of the fractional shares described below, and assuming there is no change in the number of outstanding shares of SICO common stock or the number of shares of A. O. Smith Class A common stock held by SICO, you would be entitled to receive 2,396 shares of A. O. Smith Class A common stock, which is calculated as follows: (a) 0.9850 multiplied by 8,067,252 shares of A. O. Smith Class A common stock held by SICO divided by (b) 3,317,066 shares of SICO common stock issued and outstanding immediately prior to the effective time of the merger rounding to the nearest one one-thousandth (.001) of a share (rounding upward in the case of any .0005 of a share), and then multiplied by (c) 1,000 shares of SICO common stock held by you.

A. O. Smith Common Stock

Each share of SICO common stock outstanding immediately prior to the effective time of the merger will be converted into the right to receive the number of shares of A. O. Smith common stock equal to (a)(i) 0.9850 multiplied by the number of shares of A. O. Smith common stock held by SICO immediately prior to the effective time minus (ii) the number of Escrow Shares (as described below), divided by (b) the number of outstanding shares of SICO common stock, rounding to the nearest one one-thousandth (.001) of a share (rounding upward in the case of any .0005 of a share), issued and outstanding immediately prior to the effective time of the merger (excluding dissenting shares) (the “Closing Common Exchange Ratio”).

For example, assuming there are no dissenting shares, if you currently own 1,000 shares of SICO common stock, absent the treatment of the fractional shares described below, assuming there are 500,000 Escrow Shares and that there is no change in the number of outstanding shares of SICO common stock or the number of shares of A. O. Smith common stock held by SICO, you would be entitled to receive 312 shares of A. O. Smith common stock, which is calculated as follows: (a)(i) 0.9850 multiplied by 1,559,076 shares of A. O. Smith common stock

held by SICO minus (ii) 500,000 Escrow Shares divided by (b) 3,317,066 shares of SICO common stock issued and outstanding immediately prior to the effective time of the merger rounding to the nearest one one-thousandth (.001) of a share (rounding upward in the case of any .0005 of a share), and then multiplied by (c) 1,000 shares of SICO common stock held by you.

A. O. Smith Common Stock in Escrow

Immediately prior to the effective time of the merger, the Shareholders’ Representative (as defined below in “—Indemnification—Shareholders’ Representative) and A. O. Smith will enter into an escrow agreement with an escrow agent reasonably acceptable to both SICO and A. O. Smith. At the effective time of the merger, A. O. Smith will deposit with the escrow agent stock certificates representing shares of A. O. Smith common stock equal to (a) $15,000,000 divided by (b) the average of the volume-weighted average price of trades for A. O. Smith common stock on the NYSE for the ten trading days ending on the last trading day immediately preceding the closing date (the “Escrow Shares”). The Escrow Shares will be held in escrow and distributed pursuant to the escrow agreement. The form of escrow agreement is attached as Annex F to this joint proxy statement/prospectus and is described in greater detail under “Agreements Relating to the Merger—Escrow Agreement” beginning on page 107. Each share of SICO common stock will be converted into the right to receive the number of shares of A. O. Smith common stock equal to the (a) number of Escrow Shares released from the escrow account divided by (b) the number of shares of SICO common stock, rounding to the nearest one-one thousandth (.001) of a share (rounding upward in the case of any .0005 of the share), issued and outstanding immediately prior to the merger (excluding dissenting shares) (the “Per Share Escrow Release Number”).

For example, assuming there are no dissenting shares, 500,000 Escrow Shares and 100% of such Escrow Shares are released from escrow to the former SICO stockholders, if you currently own 1,000 shares of SICO common stock, absent the treatment of the fractional shares described below and assuming there is no change in the number of outstanding shares of SICO common stock or the number of shares of A. O. Smith common stock held by SICO, you would be entitled to receive 150 shares of A. O. Smith common stock, which is calculated as follows: (a) 500,000 Escrow Shares divided by (b) 3,317,066 shares of SICO common stock and outstanding immediately prior to the effective time of the merger rounding to the nearest one-one thousandth (.001) of a share (rounding upward in the case of any .0005 of the share), and then multiplied by (c) 1,000 shares of SICO common stock held by you.

Fractional Shares

A. O. Smith will not issue any fractional shares of A. O. Smith Class A common stock or A. O. Smith common stock in connection with the merger. Instead, each record holder of SICO common stock who would otherwise be entitled to receive a fraction of a share of A. O. Smith Class A common stock or A. O. Smith common stock (after taking into account and aggregating shares of A. O. Smith Class A common stock represented by all SICO stock certificates surrendered by each record holder of SICO common stock and separately taking into account and aggregating shares of A. O. Smith common stock represented by all SICO stock certificates surrendered by each record holder of SICO common stock) will receive cash, without interest, in an amount equal to the fraction multiplied by the volume-weighted average price of trades of shares of A. O. Smith common stock on the NYSE on the last trading day immediately preceding the closing date of the merger.

In addition, in lieu of the release of any fractional Escrow Shares pursuant to the escrow agreement, each record holder of SICO common stock who would otherwise be entitled to a fraction of an Escrow Share (after taking into account and aggregating any fractional Escrow Shares to which such holder would otherwise be entitled) will receive cash, without interest, in an amount equal to the fraction multiplied by the volume-weighted average price of trades for shares of A. O. Smith common stock on the NYSE on the last trading day immediately preceding the closing date of the merger. Upon payment by A. O. Smith for any fractional Escrow Shares, such fractional Escrow Share will be canceled and retired and will cease to exist.

Exchange of Certificates; Letter of Transmittal

Prior to the completion of the merger, A. O. Smith will select an exchange agent reasonably satisfactory to SICO to hold the shares of A. O. Smith Class A common stock and A. O. Smith common stock to be issued to SICO stockholders in connection with the merger (excluding Escrow Shares). At the effective time of the merger, A. O. Smith will deposit such shares with the exchange agent. From time to time after the effective time of the merger, as necessary, A. O. Smith shall also make available cash in an amount sufficient to pay cash payable in lieu of fractional shares of A. O. Smith Class A common stock and A. O. Smith common stock, and, if required pursuant to the Merger Agreement, any dividends or other distributions on A. O. Smith Class A common stock and A. O. Smith common stock with a record date after the completion of the merger.

Letter of Transmittal

Promptly following the effective time of the merger, the exchange agent will mail to each record holder of SICO common stock a letter of transmittal and instructions for surrendering the record holder’s stock certificates in exchange for certificates representing the shares of A. O. Smith Class A common stock and A. O. Smith common stock issuable to each such holder pursuant to the merger. SICO stockholders who hold their shares in book entry form also will receive instructions for the exchange of their shares for the Merger Consideration from the exchange agent. Those holders of SICO common stock who properly surrender their SICO stock certificates (or uncertificated shares) in accordance with the exchange agent’s instructions will receive (a) the shares of A. O. Smith Class A common stock and A. O. Smith common stock issuable to each such holder pursuant to the merger, (b) cash, without interest, in lieu of any fractional share of A. O. Smith Class A common stock or A. O. Smith common stock issuable to any such holders and (c) dividends or other distributions, if any, to which they are entitled under the terms of the Merger Agreement. Following the completion of the merger, SICO will not register any transfers of SICO common stock on its stock transfer books.

Holders of SICO common stock should not send in their SICO stock certificates until they receive a letter of transmittal from the exchange agent with instructions for the surrender of SICO stock certificates.

Withholding

The exchange agent will be entitled to deduct and withhold from the Merger Consideration and from any cash dividends or other distributions, if any, to which a holder is entitled under the terms of the Merger Agreement the amounts it is required to deduct or withhold under any United States federal, state, local or foreign tax law. If the exchange agent withholds any amounts, these amounts will be treated for all purposes of the merger as having been paid to the stockholders from whom they were withheld.

Dividends and Distributions

Until SICO stock certificates are surrendered for exchange, any dividends or other distributions declared after the effective time of the merger with respect to A. O. Smith Class A common stock or A. O. Smith common stock into which shares of SICO common stock may have been converted will accrue but will not be paid. A. O. Smith will pay to former SICO stockholders any unpaid dividends or other distributions, without interest, only after such stockholders have duly surrendered their SICO stock certificates.

Smith and MergerCo, on the one hand, and SICO on the other, regarding aspects of their, and their respective subsidiaries, respective businesses, financial condition and structure, as well as other facts pertinent to the merger.

SICO agreed in the Merger Agreement to complete the Spin-Off prior to the effective time of the merger. SICO completed the Spin-Off effective January 19, 2009. For additional information regarding the Spin-Off, please see “The Companies—SICO—Recent Developments.” In connection with the Spin-Off, all intercompany obligations of SICO to Berlin Industries and Central States were transferred to SpinCo and SICO’s existing obligations to M&I Marshall & Ilsey Bank were either terminated or transferred to SpinCo.

Obligations of each of the A. O. Smith and SICO Boards of Directors with Respect to its Recommendation and Holding a Meeting of its Stockholders

Prior to the vote of the SICO stockholders and solely in response to a material event relating to SICO’s business that was unknown to SICO’s board of directors, the SICO Special Committee or the SICO board of directors may withdraw or modify its recommendation in a manner that adversely affects the transaction if the SICO board of directors or a duly constituted committee thereof determines in good faith, after consultation with financial advisors and legal counsel, that it must withdraw or modify the recommendation to comply with its fiduciary duties to SICO and its stockholders. If such recommendation is withdrawn, SICO may cancel its stockholders’ meeting without submitting the Merger Agreement to a vote.

Prior to the vote of the A. O. Smith stockholders and solely in response to a material event relating to A. O. Smith’s business that was unknown to A. O. Smith’s board of directors, the A. O. Smith’s Special Committee or the A. O. Smith board of directors may withdraw or modify its recommendation in a manner that adversely affects the transaction if the A. O. Smith board of directors or a duly constituted committee thereof determines in good faith, after consultation with financial advisors and legal counsel, that it must withdraw or modify the recommendation to comply with its fiduciary duties to A. O. Smith and its stockholders. If such recommendation is withdrawn, A. O. Smith may not cancel its stockholders’ meeting without submitting the Merger Agreement, the A. O. Smith Amended Charter and the Stock Issuance to a vote of its stockholders.

The support agreement that A. O. Smith and SICO entered into with members of the Smith Family includes a provision that restricts, for a period of one year after the termination of the Merger Agreement, the ability of such Smith Family members to support any alternative transaction that results in the termination of the Merger Agreement (as described below in “Agreements Relating to the Merger—Smith Family Support Agreement”).

NYSE Listing

Prior to the effective time of the merger, A. O. Smith will promptly prepare and submit a listing application to the NYSE covering the shares of A. O. Smith common stock to be issued in the merger and will use its commercially reasonable best efforts to cause such shares to be listed on the NYSE, subject to official notice of issuance.

Employee Benefit Matters

SICO has agreed to take the following actions prior to the effective time of the merger:

•

to terminate the Smith Investment Company Supplemental Benefit Plan and cause SpinCo to assume the obligation to make a lump sum distribution to each participant with an account balance in the Supplemental Benefit Plan;

•

to cause Berlin Industries to agree in writing to terminate and release SICO from all obligations to provide medical stop loss coverage to Berlin Industries;

•

to assign to SpinCo all obligations to pay post-retirement health benefits to former employees of SICO’s Belvedere division; provided, that upon the liquidation or dissolution of SpinCo or the distribution of substantially all of its assets, SpinCo will either terminate such post-retirement benefits or reserve an amount sufficient to satisfy any future obligations; and

•

to assign to SpinCo or a subsidiary of SpinCo sponsorship of all SICO benefit plans and SpinCo or a subsidiary of SpinCo to retain responsibility for all liability for any healthcare continuation coverage required by law.

Belvidere Environmental Matters

Pursuant to the Spin-Off, SICO transferred and assigned its ownership of the Belvidere real property, located at 725 Columbia Avenue, Belvidere, Illinois to SpinCo. SICO and SpinCo have agreed to take certain actions with respect to hazardous substances that existed, exist or shall exist in the future on, at, under or from the Belvidere property.

Assumption of Belvidere Environmental Liabilities by SpinCo

Pursuant to the Spin-Off, SpinCo assumed, and will indemnify SICO and A. O. Smith for, all liabilities related to the remediation, investigation, monitoring, claims, penalties, fines or other obligations relating to hazardous substances on the Belvidere property. SpinCo agreed to take the following steps in regard to such hazardous substances on the Belvidere property.

Closure Letter Regarding Groundwater and Regulated RCRA Units

There have been ongoing efforts to resolve certain identified issues relating to hazardous substances on the Belvidere property under the Resource Conservation and Recovery Act (“RCRA”). SpinCo agreed to take the following steps in regard to such RCRA issues on the Belvidere property:

•

pay all costs and use commercially reasonable efforts to obtain a closure letter from the Illinois Environmental Protection Agency (“IEPA”) for soil and groundwater impacts that no further investigation, remediation, monitoring or response/corrective action is required (the “Closure Letter”);

•

provide A. O. Smith with reasonable access to the Belvidere property upon request; and

•

remain solely responsible for addressing all matters that may arise in the event that the IEPA or any other governmental authority reopens or requests additional work be performed with respect to such RCRA matters after issuance of the Closure Letter.

If, upon termination of the escrow agreement, neither SpinCo nor SICO has obtained the Closure Letter, then SpinCo must reserve an amount equal to 110% of the amount deemed sufficient in the reasonable opinion of a third party environmental consultant to fund the actions necessary to obtain the Closure Letter.

Investigation of Environmental Law Violations on Belvidere Property

If SpinCo becomes aware of any violation of environmental laws related to a release or threatened release of hazardous substances on the Belvidere property which was present on the Belvidere property prior to the

effective time of the merger, other than the RCRA issues described in the previous section, SpinCo will take the following steps regarding such violations:

•

enroll the Belvidere property into the Illinois Site Remediation Program to the extent reasonably required to comply with environmental laws;

•

conduct such actions that are required to obtain a focused No Further Remediation Letter (“NFR”) in regard to the violation in question to the extent reasonably required by environmental law;

•

provide A. O. Smith with reasonable access to the Belvidere property upon request; and

•

remain solely responsible for all matters raised in the event the IEPA or any other governmental authority reopens or requests any additional work to be performed on the Belvidere property in connection with such violation after issuance of an NFR.

If, upon termination of the escrow agreement, a violation triggering the need to obtain an NFR has been discovered and SpinCo has not obtained the NFR, then SpinCo must reserve an amount equal to 110% of the amount deemed sufficient in the reasonable opinion of a third party environmental consultant to fund the actions necessary to obtain the NFR.

Directors and Officers Exculpation and Insurance

For at least six years after the effective time of the merger, MergerCo’s certificate of formation and operating agreement will contain provisions that are not less favorable to SICO’s directors and officers than SICO’s current organizational documents with respect to exculpation of such directors and officers for periods at or prior to the effective time of the merger.

For at least six years after the effective time of the merger, A. O. Smith will maintain for the benefit of SICO’s directors and officers, as of the date of the Merger Agreement and as of the effective time, an insurance policy covering events prior to the effective time of the merger that is not less favorable in the aggregate than any policy of A. O. Smith for its directors and officers.

A. O. Smith Insiders

The A. O. Smith board of directors has adopted a resolution consistent with Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) so that the disposition or acquisition by an officer or director of A. O. Smith of shares of A. O. Smith common stock pursuant to this Merger Agreement, the merger and other transactions contemplated thereby, will be an exempt transaction under Rule 16b-3 under the Exchange Act.

Notice of Breach

Each of A. O. Smith and SICO shall give each other prompt written notice if its executive officers have knowledge of any breach or violation of any of its respective representations and warranties, covenants or agreements contained in the Merger Agreement.

Litigation

Each party shall promptly notify each other party if it has knowledge of any claim arising out of the Merger Agreement or the transactions contemplated thereby, which notice shall describe such claim in reasonable detail. SICO will control the defense of any transaction-related claim to the extent it involves SICO, SpinCo, Berlin Industries, Central States or any of their respective affiliates, directors, officers or employees (other than A. O. Smith and its directors, officers and employees). A. O. Smith will control the defense of any transaction-related claim to the extent it involves A. O. Smith, MergerCo or any of their respective affiliates, directors, officers or employees. If A. O. Smith controls the defense, SICO has the right to approve A. O. Smith’s selection of legal counsel, which approval may not be unreasonably withheld or delayed, and SICO has the right at its expense to

participate in the defense with counsel it chooses. A. O. Smith may only settle a transaction-related claim with SICO’s prior written consent, which consent may not be unreasonably withheld or delayed. After the merger, the Shareholders’ Representative will take the place of SICO in connection with such procedures relating to transaction-related claims.

Cancellation of Stock

As soon as possible after the effective time of the merger, A. O. Smith will cause MergerCo to transfer to A. O. Smith all of the A. O. Smith Class A common stock and A. O. Smith common stock MergerCo holds and A. O. Smith shall cancel such shares.

Restrictions on SpinCo

From the date of the Merger Agreement until five years after the effective time of the merger, SpinCo will not repurchase or otherwise acquire any of its equity interests or make or pay any dividend or distribution on any of its equity interests other than (a) distributions for income taxes permitted by SpinCo’s operating agreement or (b) other dividends, distributions, repurchases or acquisitions if prior to the date of such dividend, distribution, repurchase or acquisition, SpinCo deposits $4,000,000 into escrow to secure SpinCo’s indemnification obligations. If SpinCo deposits $4,000,000 in escrow prior to the release of all of the Escrow Shares pursuant to the escrow agreement, A. O. Smith will cause an amount of Escrow Shares with an aggregate value of $4,000,000 to be released from escrow in accordance with the escrow agreement.

Resignation of Officers and Directors

SICO’s officers and directors will resign prior to the effective time of the merger and SICO will provide evidence of such resignations to A. O. Smith.

Taxes

SICO will pay all SICO taxes due on or prior to the closing date including any estimated tax payments due on or prior to the closing date in accordance with applicable law.

Smith and its subsidiaries and their respective officers, directors, employees, owners, agents, affiliates and their respective successors and assigns are indemnified by SpinCo and out of the Escrow Shares from and against losses, costs, obligations, liabilities, settlement payments, fines, penalties, damages, expenses, taxes or other charges, directly or indirectly resulting from or arising out of the following:

•

any liabilities of any nature, whether accrued, absolute, contingent or otherwise incurred by SICO, SpinCo or any SICO subsidiary prior to the effective time of the merger, or to the extent arising out of any circumstances with respect to SICO, SpinCo, any SICO subsidiary or any of their respective business operations which occurred prior to the effective time of the merger;

•

the exercise by any stockholder of SICO of dissenters’ rights pursuant to the Merger Agreement (taking into account the benefit of A. O. Smith not having to pay any such stockholders any Merger Consideration that such stockholder would have been entitled to);

•

any rights to indemnification, reimbursement or compensation from SICO asserted by any individual who served as director or officer of SICO prior to the effective time of the merger, whether pursuant to any of SICO’s organizational documents, contracts or otherwise and whether or not related to claims pending on, or asserted after, the closing date;

•

any taxes of SICO for any pre-closing tax period;

•

certain reductions or denials of certain tax benefits and tax refunds;

The representations, warranties, covenants and agreements given or made by SICO in the Merger Agreement or any ancillary agreement shall survive the closing for a period of five years after the closing date with respect to indemnification claims against SpinCo and for a period of two years after the closing date with respect to indemnification claims from the Escrow Shares.

Indemnification by A. O. Smith

SICO’s former stockholders and each of their respective officers, directors, employees, owners, agents, affiliates and their successors and assigns are indemnified by A. O. Smith from and against losses, costs, obligations, liabilities, settlement payments, fines, penalties, damages, expenses or other charges, related to:

•

any inaccuracy in or breach of any representation or warranty of A. O. Smith or MergerCo in the Merger Agreement or any ancillary agreement to which A. O. Smith or MergerCo is a party; or

•

any breach of any covenant or agreement on the part of A. O. Smith or MergerCo in the Merger Agreement;

The representations, warranties, covenants and agreements given or made by A. O. Smith or MergerCo in the Merger Agreement or any ancillary agreement shall survive the closing for a period of 5 years after the closing date except for the representations and warranties regarding (a) the absence of any violation of, any legal requirements applicable to A. O. Smith or its subsidiaries or their properties or assets as a result of entering into and carrying out the obligations contained in the Merger Agreement and (b) the accuracy of information supplied for inclusion in this joint proxy statement/prospectus and other similar documents, which expire at the effective time of the merger.

Shareholders’ Representative

Upon the approval of the Merger Agreement, each former SICO stockholder will be deemed to have irrevocably appointed SpinCo, as its, his or her true and lawful attorney-in-fact and agent (the “Shareholders’ Representative”). The Shareholders’ Representative will act solely and exclusively on behalf of the former SICO stockholders with regard to matters pertaining to the indemnification by the former SICO stockholders and all matters under the escrow agreement or relating to Escrow Shares. A. O. Smith and any other person may absolutely rely upon the actions of the Shareholders’ Representative. The Shareholders’ Representative will pay all expenses incurred by the Shareholders’ Representative in performing its duties.

Indemnification Procedures

As soon as reasonably practicable after becoming aware of any claim that may give rise to indemnification obligations, A. O. Smith or SICO, as applicable, shall give written notice (“Claim Notice”) to the party or parties from which indemnification is sought. The Claim Notice shall describe the claim in reasonable detail and indicate the amount of damages that have been suffered by the indemnified party.

If a third party makes a claim against an indemnified party, the indemnifying party will have the right upon written notice (a “Control Notice”) to conduct the defense against such a third party claim in its own name or, if necessary, in the name of the indemnified party, subject to the following requirements:

•

the indemnifying party must acknowledge in writing that any damages that may be assessed against the indemnified party constitute damages for which the indemnified party may be indemnified under the Merger Agreement;

•

the indemnifying party may not control the defense of a suit or proceeding involving criminal liability or in which any relief other than monetary damages is sought against the indemnified party;

•

the indemnified party must cooperate with the indemnifying party and shall have the right, at its own expense, to participate in the defense;

•

the indemnifying party will not enter into any settlement of any third party claim or stop defending any third party claim without the prior written consent of the indemnified party, provided that the indemnified party may withhold its consent if injunctive or other equitable relief would be imposed against the indemnified party or such settlement or cessation would lead to material liability or financial obligation for the indemnified party, for which the indemnified party is not entitled to indemnification;

•

the indemnified party may employ a separate counsel to be paid by the indemnifying party if the indemnified party is named in the third party claim and it is determined that the indemnified party and indemnifying party have conflicting interests or different defenses in connection with the third party claim; and

•

the indemnifying party consents to the nonexclusive jurisdiction of any court in which a claim or cause of action in respect to a third party claim is brought against any indemnified party.

Furthermore, the Shareholders’ Representative shall act as nominee for the former SICO stockholders with respect to any claim for indemnification against the Escrow Shares.

Limits on Indemnification; Calculation of Damages

When pursuing the collection of damages pursuant to the indemnification provisions, the A. O. Smith indemnified parties must first proceed against SpinCo before pursuing any claim against the Escrow Shares. If SpinCo does not satisfy all damages for which payment is due with respect to a claim within 15 days after agreement that payment is due or a final judgment, the A. O. Smith indemnified parties may proceed against the Escrow Shares, which represent the sole and exclusive source of satisfaction and payment for any indemnification claims against the former SICO stockholders.

Damages will be calculated after giving effect to any amount received by the indemnified party under any insurance coverage or any contribution from any third party for the claim and after giving effect to any tax benefit resulting from the claim when realized by the indemnified party. For this purpose, tax benefits with respect to A. O. Smith and its subsidiaries are treated as realized only to the extent that by the due date (including extensions) of the tax return for the last period from which losses or credits can be carried back, A. O. Smith and its subsidiaries have not otherwise generated a loss or credit to offset the income or tax that would have been reduced by the potential tax benefit. If a tax benefit will not be realized until after the indemnification payment is due, the indemnifying party is required to pay the full indemnification amount and the indemnified party will be obligated to pay the amount of the tax benefit to the indemnifying party when realized. The right to receive payment for these tax benefits shall survive indefinitely.

The A. O. Smith indemnified parties do not have any rights to indemnification for damages pursuant to the Merger Agreement to the extent that any such damages result from or arise out of any information of A. O. Smith that is incorporated by reference in this joint proxy statement/prospectus.

Furthermore, SpinCo waives any right to:

•

seek contribution or other payment from SICO with respect to damages for which SpinCo is required to indemnify A. O. Smith indemnified parties; or

•

bring a claim against current or former directors of A. O. Smith as a result of damages for which SpinCo is required to indemnify A. O. Smith indemnified parties.

Payment for Tax Benefit Items

A. O. Smith is required to pay to the Shareholders’ Representative for the account of the former SICO stockholders the amount of any tax refunds relating to SICO received by A. O. Smith or its subsidiaries after the effective time with respect to any pre-closing tax period and any tax benefits relating to SICO (including SICO’s net operating loss carryforwards) actually realized by A. O. Smith or its subsidiaries after the effective time of the merger. For this purpose, tax benefits with respect to A. O. Smith and its subsidiaries are treated as realized to the extent that, by the due date (including extensions) of the tax return for the last period from which losses or credits can be carried back, A. O. Smith and its subsidiaries have not otherwise generated a loss or credit to offset the income or tax that would have been reduced by the potential tax benefits. The right to receive payment for these tax benefits shall survive indefinitely.

Termination

Under the terms of the Merger Agreement, the Merger Agreement may be terminated at any time prior to the effective time of the merger:

•

by mutual written consent of A. O. Smith, MergerCo and SICO;

100

•

by either of SICO, on one hand, or A. O. Smith or MergerCo, on the other hand:

–

if the required SICO stockholder vote is not obtained at the SICO stockholder meeting or the required A. O. Smith stockholder votes are not obtained at the A. O. Smith stockholder meeting;

–

if any governmental authority of competent jurisdiction has issued an injunction or taken any other action, which permanently restrains, enjoins or otherwise prohibits the consummation of the merger; or

–

if the consummation of the merger does not occur on or before September 30, 2009;

•

by A. O. Smith or MergerCo, on one hand, or SICO, on the other hand, if there has been a breach of any representation, warranty, covenant or agreement of the other party contained in the Merger Agreement, which would result in a failure of any of the closing conditions of the non-breaching party, that cannot reasonably be cured prior to September 30, 2009; provided, however, that the non-breaching party shall have given the breaching party written notice of such breach, delivered at least 20 days prior to such termination; or

•

by A. O. Smith or MergerCo, on one hand, or SICO, on the other hand, if the board of directors of the other party has withdrawn or modified its recommendation to consummate the merger in a manner that adversely affects the transactions contemplated by the Merger Agreement.

101

A. O. SMITH AMENDED CHARTER

The following summary describes proposed changes to the A. O. Smith Existing Charter by the A. O. Smith Amended Charter. This summary may not contain all of the information about the A. O. Smith Amended Charter that is important to you. The A. O. Smith Amended Charter is attached as Annex B to this joint proxy statement/prospectus and is incorporated by reference in this joint proxy statement/prospectus, and A. O. Smith encourages you to read it carefully in its entirety for a more complete understanding.

General

The Merger Agreement provides that, as a condition to the merger, the A. O. Smith Existing Charter be amended and restated and filed with the Secretary of State for the State of Delaware. The proposed A. O. Smith Amended Charter will provide for:

•

an increase in the percentage of members of the A. O. Smith board of directors that holders of A. O. Smith common stock, voting as a separate class, elect from 25% to 33-¹/₃% of the members of the board of directors (if such 33-¹/₃ % is not a whole number, then rounding up to the nearest whole number of directors (or four of the ten directors));

•

shares of A. O. Smith Class A common stock to convert automatically into A. O. Smith common stock, subject to certain exceptions, upon transfer to unaffiliated third parties; and

•

Increase in the Number of Authorized Shares of A. O. Smith Class A Common Stock

Pursuant to the merger, A. O. Smith will issue new shares of A. O. Smith Class A common stock and A. O. Smith common stock to the former SICO stockholders. The A. O. Smith Existing Charter does have a sufficient number of authorized but unissued shares of A. O. Smith Class A common stock for A. O. Smith to issue the requisite number of shares of A. O. Smith Class A common stock included in the Merger Consideration. The A. O. Smith Amended Charter will increase, solely for purposes of completing the merger, the authorized number of shares of A. O. Smith Class A common stock from 14,000,000 shares to 22,067,252 shares. Following the effective time of the merger, A. O. Smith will cancel the shares of A. O. Smith Class A common stock currently held by SICO, as described above in “The Merger Agreement—Consideration to be Received in the Merger” beginning on page 87. Under the A. O. Smith Amended Charter, A. O. Smith will be prohibited from reissuing such shares of A. O. Smith Class A common stock after they are cancelled, so that the total number of shares of A. O. Smith Class A common stock that A. O. Smith is authorized to issue will return to 14,000,000.

Increase in the Number of Directors the Holders of A. O. Smith Common Stock are Entitled to Elect

Currently, the A. O. Smith Existing Charter provides that the holders of A. O. Smith common stock, voting as a class, elect 25% of the members of A. O. Smith’s board of directors. The A. O. Smith Amended Charter will increase this percentage to 33-¹/₃%. If 33-¹/₃% of the authorized number of directors is not a whole number, then the holders of A. O. Smith common stock will be entitled to elect the nearest higher whole number of directors that is at least 33-¹/ ₃% of the board of directors. Holders of A. O. Smith Class A common stock, voting as a separate class, will elect the remaining directors. The A. O. Smith Board currently consists of ten directors, with three elected by the A. O. Smith common stock. If A. O. Smith Proposal 2 passes and the A. O. Smith Amended

102

Charter takes effect, the holders of A. O. Smith common stock will elect four of the ten directors. Effective upon consummation of the merger, the A. O. Smith board of directors has designated Mr. Ronald D. Brown, who is currently a director elected by holders of A. O. Smith Class A common stock as a director elected by the holders of the A. O. Smith common stock to serve until the next annual meeting of the A. O. Smith stockholders.

Conversion of A. O. Smith Class A Common Stock Upon Transfer

The A. O. Smith Amended Charter provides for the automatic conversion to A. O. Smith common stock of any shares of A. O. Smith Class A common stock that are transferred to transferees that are not Permitted Transferees (as defined below in this section). If, after the effective time of the merger, a beneficial owner of shares of A. O. Smith Class A common stock as of the effective time of the merger (an “Existing Class A Holder”) transfers the beneficial ownership of shares of A. O. Smith Class A common stock, whether by sale, assignment, gift, bequest, appointment or otherwise, to a transferee who is not a Permitted Transferee, then each share of A. O. Smith Class A common stock that is transferred shall automatically be converted into one share of A. O. Smith common stock. The A. O. Smith Amended Charter contains a provision providing a holder of A. O. Smith Class A common stock 30 days to cure an inadvertent non-permitted transfer or a non-permitted transfer made with a bona fide belief that it was a not a non-permitted transfer. When determining whether this automatic conversion applies, “Permitted Transferee” shall mean:

•

with respect to any Existing Class A Holder that is a natural person (each of the following will be referred to as a “Related Party”) the parents, grandparents, siblings, spouses, ex-spouses and issue (either natural or adoptive), spouses and ex-spouses of issue (either natural or adoptive):

–

any trust for the benefit of, the estate of or the legal representative of, any of such Existing Class A Holder or such persons, provided, that any such trust shall qualify as a Related Party notwithstanding that a remainder interest in such trust is for the benefit of any other person;

–

any partnership the partners of which are any such Existing Class A Holder or one or more of such persons; or

–

any limited liability company, corporation or other entity the ownership interests of which are held by any such Existing Class A Holder or one or more of such persons; or

•

with respect to any Existing Class A Holder that is a trust, partnership, limited liability company, corporation or other entity:

–

the beneficiaries of such trust;

–

the partners, members, stockholders or other equity owners of such partnership, limited liability company, corporation or other entity; and

–

the Related Parties of such persons;

•

any lineal descendant of Lloyd R. Smith and any such lineal descendant’s parents, grandparents, siblings, spouses, ex-spouses and issue (either natural or adoptive), spouses and ex-spouses of issue (either natural or adoptive) and:

–

any trust for the benefit of, the estate of or the legal representative of, any such persons, provided, that any such trust shall qualify notwithstanding that a remainder interest in such trust is for the benefit of any other person;

–

any partnership the partners of which are one or more of such persons; or

–

any limited liability company, corporation or other entity the ownership interests of which are held by one or more of such persons.

The A. O. Smith Existing Charter does not include a provision providing for the automatic conversion of A. O. Smith Class A common stock upon its transfer.

103

Automatic Class A Common Stock Conversion Trigger

The A. O. Smith Amended Charter also includes a provision which provides that once the outstanding shares of A. O. Smith Class A common stock fall below 2,397,976, which is approximately 8% of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock as of the date of the Merger Agreement, each outstanding share of A. O. Smith Class A common stock will convert into a share of A. O. Smith common stock. The A. O. Smith Existing Charter does not include such a provision.

Mechanics of Conversion

In the event of an automatic conversion of shares of A. O. Smith Class A common stock, the certificates formerly representing outstanding shares of A. O. Smith Class A common stock subject to automatic conversion will be deemed to represent a like number of shares of A. O. Smith common stock.

104

AGREEMENTS RELATING TO THE MERGER

The following is a summary of the material provisions of various agreements entered or to be entered into by the parties in connection with or related to the merger. This summary may not contain all of the information that is important to you. You should refer to the full text of the agreements which are attached hereto and are incorporated by reference in this joint proxy statement/prospectus. We encourage you to read them carefully in their entirety for a complete understanding.

SICO Support Agreement

As a condition to the willingness of A. O. Smith to enter into the Merger Agreement, SICO entered into a support agreement with A. O. Smith. The full text of this support agreement is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference. Pursuant to this agreement, SICO agreed to vote its shares of A. O. Smith Class A common stock and A. O. Smith common stock (including shares of A. O. Smith Class A common stock and A. O. Smith common stock acquired during the term of the support agreement) (a) in favor of the merger and the other transactions contemplated thereby, including the Merger Agreement and any other matter that is on the ballot that facilitates the merger, and (b) against any proposal that would reasonably be expected to prevent or materially delay the consummation of the merger. These shares represent approximately 78.9% of the voting power of the total outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, voting together as a single class, and approximately 97.1% of the voting power of the total outstanding shares of A. O. Smith Class A common stock, voting as a separate class.

Further, while the agreement is in effect and only with respect to SICO’s shares of A. O. Smith Class A common stock and A. O. Smith common stock, SICO has agreed not to:

•

sell, transfer, pledge, encumber, assign or otherwise dispose of any shares, or any interest therein;

•

enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, encumbrance or other disposition of, or limitation on the voting rights of, any of the shares; or

•

commence or participate in any class action with respect to any claim against A. O. Smith and MergerCo relating to the negotiation, execution and delivery of the support agreement, the Merger Agreement or the consummation of the merger.

The support agreement will terminate upon the earlier of the termination of the Merger Agreement, the withdrawal of the A. O. Smith board of directors recommendation and the effective time of the merger.

Smith Family Support Agreement

As a condition to the willingness of A. O. Smith and SICO to enter into the Merger Agreement, certain members of the Smith Family entered into a support agreement. The full text of this support agreement is attached as Annex D to this joint proxy statement/prospectus and is incorporated herein by reference. Pursuant to this agreement, such members of the Smith Family agreed to vote their shares of SICO common stock (including any shares of SICO common stock acquired during the term of the support agreement) (a) in favor of the merger and the other transactions contemplated thereby, including the Merger Agreement and any other matter that is on the ballot that facilitates the merger, and (b) against any proposal that would reasonably be expected to prevent or

105

materially delay the consummation of the merger. These shares represent approximately 52.7% of the voting power of the total outstanding shares of SICO common stock. If the Merger Agreement terminates because the SICO board of directors modifies or withdraws its recommendation, these members of the Smith Family have agreed for a period of one year after the termination of the Merger Agreement not to vote in favor of any proposal that resulted in or is related to the change of the SICO board recommendation.

Further, while the agreement is in effect and only with respect to the shares of SICO that each such member of the Smith Family owns, each such member of the Smith Family has agreed not to:

•

sell, transfer, pledge, encumber, assign or otherwise dispose of any shares, or any interest therein;

•

seek dissenter’s rights from the merger under Nevada law; or

•

commence or participate in any class action with respect to any claim against A. O. Smith and MergerCo relating to the negotiation, execution and delivery of the support agreement, the merger Agreement or the consummation of the merger.

The support agreement will terminate upon the earlier of the termination of the Merger Agreement, the withdrawal of the A. O. Smith board recommendation and the effective time of the merger.

Because the shares of SICO common stock held by the members of the Smith Family who signed the Smith Family support agreement represent approximately 52.7% of the voting power of the total outstanding shares of SICO common stock, stockholders of SICO holding voting power sufficient to approve the proposal to approve the Merger Agreement have agreed to vote in favor of the proposal to approve the Merger Agreement at the SICO special meeting.

Stockholder Agreement

As a condition to the willingness of A. O. Smith to enter into the Merger Agreement and to the formation of the voting trust contemplated by the voting trust agreement described below, certain members of the Smith Family entered into a stockholder agreement with A. O. Smith relating to the shares of A. O. Smith Class A common stock and A. O. Smith common stock they will own following the consummation of the merger. The full text of this stockholder agreement is attached as Annex E to this joint proxy statement/prospectus and is incorporated herein by reference. Pursuant to this agreement, such stockholders agreed to certain standstill and other obligations with respect to the affairs of A. O. Smith during the term of the agreement.

Specifically, such members of the Smith Family agreed, while the stockholder agreement is in effect, that they will not, without prior written approval of the A. O. Smith board of directors:

•

knowingly participate in, or consent to the taking of any stockholder action by consent without a meeting other than in response to a proxy contest initiated by an unrelated third party or otherwise initiated or not opposed by A. O. Smith;

•

submit or solicit stockholder approval for any proposal for consideration at any A. O. Smith annual or special meeting;

•

agree with any other person to take any of the actions described above.

106

Holders of A. O. Smith Class A common stock are permitted under the stockholder agreement, without approval of the board of directors of A. O. Smith, (a) to solicit proxies or consents and take action by written consent, solely regarding matters affecting the rights, preferences or privileges of the A. O. Smith Class A common stock and not shared with the holders of A. O. Smith common stock and (b) to elect directors with respect to the A. O. Smith Class A common stock in accordance with the A. O. Smith Amended Charter.

The stockholder agreement will take effect upon the effective time of the merger and will terminate upon the earlier of (a) any termination of the Merger Agreement, (b) three years after the effective time of the merger, (c) the date that all outstanding A. O. Smith Class A common stock automatically converts into A. O. Smith common stock in accordance with the A. O. Smith Amended Charter (described above in “A. O. Smith Amended Charter”), (d) A. O. Smith publicly announces it is being acquired or (e) ten days after a solicitation to acquire A. O. Smith if A. O. Smith does not publicly reject the offer.

Escrow Agreement

Pursuant to the Merger Agreement, A. O. Smith, SpinCo (both in its individual capacity and as the Shareholders’ Representative) and an escrow agent will enter into an escrow agreement for the purpose of providing a source of payment for a period of two years to reimburse A. O. Smith for the payment of any losses for which A. O. Smith is entitled to indemnification pursuant to the Merger Agreement (as discussed above under “The Merger Agreement—Indemnification”). The full text of the form of escrow agreement is attached hereto as Annex F to this joint proxy statement/prospectus and is incorporated herein by reference.

Establishment of Escrow Fund

A. O. Smith will deposit with the escrow agent a number of shares of A. O. Smith common stock that would otherwise be deliverable to holders of SICO common stock pursuant to the Merger Agreement with a market value as of the effective time of the merger that is equal to $15,000,000. In addition, SpinCo may deposit cash with the escrow agent up to five times during the term of the escrow agreement to obtain the release of Escrow Shares. The market value of any Escrow Shares that are released pursuant to any such cash substitution will be determined as of the effective time of the merger.

At the effective time of the merger, A. O. Smith, on behalf of SICO’s stockholders, will deposit with the escrow agent stock certificates representing the Escrow Shares or a book-entry with respect to the Escrow Shares in the escrow agent’s account. Until delivered to A. O. Smith, the Escrow Shares equal to each SICO stockholder’s pro rata percentage of the Escrow Shares shall be registered in the name of such SICO stockholder. Each SICO stockholder’s pro rata percentage will be equal to the number of shares of SICO common stock held by such SICO stockholder divided by the total number of shares of SICO common stock held by all SICO stockholders (other than shares cancelled in accordance with the Merger Agreement or dissenting shares).

Further, the SICO stockholders are entitled to receive any dividends, interest or other earnings earned on the Escrow Shares while in escrow and SpinCo is entitled to receive any interest or other earnings on the escrow cash. Any such earnings will be the sole and exclusive property of the SICO stockholders with respect to earnings on the Escrow Shares and SpinCo with respect to the earnings on the escrow cash. Each SICO stockholder will have the right to vote and grant consents with respect to its Escrow Shares.

If any portion of the escrow fund consists of cash, the escrow agent will invest such cash at the joint written instructions of A. O. Smith and the Shareholders’ Representative.

Indemnification Claims

To make an indemnification claim pursuant to the Merger Agreement (such claims are described above under “The Merger Agreement—Indemnification”) to be paid from the escrow fund, A. O. Smith must provide the Shareholders’ Representative a Claim Notice by the deadline provided in the Merger Agreement.

107

Undisputed Claims

If the Shareholders’ Representative does not provide a Counter Notice disputing either A. O. Smith’s indemnification claims or estimate within 30 days following receipt by the Shareholders’ Representative of the Claim Notice, then the claim will be deemed established under the escrow agreement, and the escrow agent will promptly deliver to A. O. Smith from the escrow fund:

•

cash in an amount equal to the indemnification amount claimed; and

•

if the cash is not sufficient to satisfy the indemnification amount, shares in an amount equal to the unsatisfied indemnification amount, with the market value of such Escrow Shares to be determined as of the date of the delivery of the Escrow Shares.

Disputed Claims

If the Shareholders’ Representative provides a Counter Notice within 30 days following the receipt by the Shareholders’ Representative of the Claim Notice, the escrow agent will deliver within 3 business days the appropriate amount of cash and/or shares only in accordance with

•

joint written instructions of A. O. Smith and the Shareholders’ Representative; or

•

a final judgment with no further right to appeal, upon an award rendered by a court of competent jurisdiction.

Termination of Escrow

The escrow agent shall release the escrowed cash in the escrow fund to SpinCo and the Escrow Shares in the escrow fund to the former SICO stockholders in accordance with their respective pro rata percentage, 24 months after the effective time of the merger. However, the escrow fund is to retain 110% of the aggregate amount of any indemnification claims outstanding on the escrow release date until all such claims have been resolved.

Early Release of Shares

If, prior to the termination of the escrow, all legal proceedings related to the merger have been settled by the parties thereto or there has been a final judgment with respect to such legal proceedings, A. O. Smith and the Shareholders’ Representative will provide joint written instructions to the escrow agent authorizing the escrow agent to distribute a portion of the escrow fund to the former SICO stockholders. After such distribution, the escrow fund must retain an aggregate value of $7,500,000 of escrowed cash and Escrow Shares, plus an amount equal to the amount by which aggregate indemnification amount of all pending claims exceeds $3,000,000. Each former SICO stockholder will receive a portion of the escrow fund distributed to SICO stockholders in accordance with such stockholder’s respective pro rata percentages.

Voting Trust Agreement

In connection with the Merger Agreement, certain members of the Smith Family may enter into a voting trust agreement. After giving effect to the merger, these members of the Smith Family are expected to own approximately 41.4% of the total voting power of the outstanding shares of A. O. Smith Class A common stock and A. O. Smith common stock, taken together as a single class, and approximately 51.6% of the voting power of the outstanding shares of A. O. Smith Class A common stock, as a separate class. The full text of the form of voting trust agreement is attached as Annex G to this joint proxy statement/prospectus and is incorporated herein by reference. Pursuant to this agreement, each such member of the Smith Family will agree to deposit his, her or its shares of A. O. Smith Class A common stock and A. O. Smith common stock with the trustees and, in effect, assign all rights and powers incident to the ownership of those shares to the trustees. Such members of the Smith Family may withdraw part or all of their shares held in trust upon the trustees’ unanimous consent, which shall not be withheld without good cause.

108

Rights and Duties of Trustees

Among others specified in the voting trust agreement, each trustee will have the following duties and rights with respect to the shares held in trust:

•

vote the shares either in person or by proxy;

•

make pro rata distributions to the beneficiaries of any cash or property received by reason of the shares;

•

give the beneficiaries prompt notice of the issuance or granting of any warrants or rights to subscribe to any security issued by A. O. Smith;

•

unless directed otherwise, use and/or exchange A. O. Smith common stock held by the trust as consideration for the purchase of A. O. Smith Class A common stock available to the trust from time to time;

•

become parties to or participate in proceedings affecting the shares, A. O. Smith or the powers and duties of the trustees;

•

exchange shares of A. O. Smith common stock held in trust for shares of A. O. Smith Class A common stock;

•

borrow or arrange for borrowing for the purpose of purchasing additional shares;

•

vote for himself or herself as a director of A. O. Smith;

•

take action with the approval of a majority of the trustees then qualified as trustees;

•

keep proper records with respect to the trust assets and beneficiaries; and

•

hold office until he or she resigns, dies, becomes incapacitated, or refuses to act or is removed by the beneficiaries possessing trust interests representing at least 66-²/₃% of the voting power of all shares held by the trustees.

Transfers and Withdrawals

The shares held in trust are transferable only on the books of the trustees, where the transferee will be substituted for the previously registered owner. The transferee, however, must be a member of the Smith Family. Additionally, if the transferee is not a depositor under the voting trust agreement, then the transferee will not become a depositor simply as a result of the transfer.

Whenever a beneficiary wishes to withdraw from the trust, or sell or otherwise transfer or dispose of any or all of his, her or its shares deposited in the trust, or whenever such beneficiary ceases to be eligible to be a party to the voting trust agreement, the following procedures must be observed:

•

if the beneficiary is no longer an eligible party to the voting trust agreement, the trustees must give notice to the stockholder of the termination of eligibility;

•

if the beneficiary intends to withdraw or transfer his, her or its shares, the trustees must give notice of the intended withdrawal and/or transfer to the trustees’ secretary;

•

if shares of A. O. Smith Class A common stock are being transferred or withdrawn, they shall automatically be exchanged for shares of A. O. Smith common stock held by the trust to the extent available in the trust;

•

if a beneficiary provides a notice of withdrawal, it will constitute an offer to sell his, her or its shares to the trust at a price per share equal to the average closing sales price per share of A. O. Smith common stock as traded on the NYSE for the ten trading days prior to the proposed withdrawal;

109

•

if sufficient interest has been expressed by the beneficiaries upon their deposit with the trust, trustees may do any of the following: (a) purchase A. O. Smith common stock from other sources for the purpose of exchanging shares of the common stock for shares of A. O. Smith Class A common stock pursuant to the point above; (b) purchase for cash some or all of the shares that are A. O. Smith Class A common stock; or (c) subject to the prior written consent of the beneficiaries, purchase for cash some or all of the shares that are A. O. Smith common stock;

•

a beneficiary is permitted to withdraw his, her or its offer of sale at any time prior to the time of transfer or withdrawal; and

•

if the trust does not purchase any or all of the shares, the withdrawing beneficiary may withdraw the shares that were not purchased and the trustees will cause A. O. Smith to promptly deliver to that withdrawing beneficiary certificates or other evidence of ownership as may be provided by A. O. Smith for such shares.

The voting trust agreement may be terminated at any time by vote of the beneficiaries having trust interests representing at least 75% of the voting power of the shares held in trust. Otherwise, the agreement will remain in effect for 30 years, and will automatically renew for additional 30 year renewal periods thereafter.

110

ACCOUNTING TREATMENT

The pending transaction between A. O. Smith and SICO will be accounted for as a reverse acquisition with SICO as the accounting acquirer and A. O. Smith as the accounting acquiree (which is the surviving entity for legal purposes). As this is a common control transaction under FAS 141(R) Business Combinations, the transaction will be accounted for as an equity transaction under FAS 160 Noncontrolling Interests in Consolidated Financial Statements an amendment of ARB No. 51 as the acquisition of a noncontrolling interest and will not require purchase accounting.

Furthermore, because SICO is treated as the continuing reporting entity for accounting purposes, the reports filed by A. O. Smith, as the surviving corporation in the transaction, after the date of the transaction will parallel the financial reporting required under United States generally accepted accounting principles and SEC reporting rules as if SICO were the legal successor to its reporting obligation as of the date of the transaction. Accordingly, prior period financial information presented in the A. O. Smith financial statements will reflect the historical activity of SICO.

REGULATORY APPROVALS

To complete the merger, A. O. Smith and SICO are required to obtain approvals or consents from, or make filings with, various regulatory authorities. These regulatory approvals and filings include (a) the IRS Letter Ruling, which is described in “Material United States Federal Income Tax Consequences of the Merger” and (b) confirmation from the NYSE that no supplemental listing application is required with respect to the Stock Issuance. A. O. Smith and SICO currently are not aware of additional material governmental consents, approvals or filings that are required prior to the parties’ consummation of the merger, and the merger and transactions contemplated by the Merger Agreement are not subject to the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. In the event additional material consents, approvals or filings are required to complete the merger, it is presently contemplated that such consents, approvals or filings will be sought or made. The parties’ obligations to complete the merger are conditioned upon receipt of required regulatory approvals and the absence of any pending action by a court or the government to enjoin the merger, make the consummation of the merger illegal or otherwise prohibit the merger. See “The Merger Agreement—Conditions to Obligations to Complete the Merger” beginning on page 96.

A. O. Smith and SICO will seek to complete the merger in the second quarter of 2009. While A. O. Smith and SICO currently do not expect any action by a regulatory authority to enjoin or prohibit the merger or otherwise impose conditions upon or changes to the merger, there can be no assurance that there will not be any such actions, conditions or changes, and any such actions, conditions or changes could have the effect of delaying completion of the merger or imposing additional costs on the parties or limiting revenues following the merger, any of which might have a material adverse effect on A. O. Smith or MergerCo following the merger. Neither A. O. Smith nor SICO is obligated to complete the merger if any such conditions, individually or in the aggregate, would result in a material adverse change under the terms of the Merger Agreement. See “Risk Factors” beginning on page 29.

For information relating to existing or potential future legal proceedings seeking to enjoin the merger, among other things, see “The Merger—Legal Proceedings Regarding the Merger” beginning on page 84 and “Risk Factors” beginning on page 29.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

A. O. Smith Stockholders

There are no United States federal income tax consequences of the merger to A O. Smith stockholders with respect to their shares of A. O. Smith Class A common stock or A. O. Smith common stock.

SICO Stockholders

The following discussion summarizes the material United States federal income tax consequences of the merger to SICO’s stockholders. This discussion is not a complete analysis of all the potential United States federal income tax consequences of the merger to SICO stockholders, nor does it address any tax consequences arising under any state, local or foreign tax laws, the federal estate tax or gift tax laws, or any other United States federal tax laws. This discussion is based on the Code, Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the IRS, all as in effect on the date hereof. These authorities may change, possibly retroactively, resulting in United States federal income tax consequences different from those discussed below.

This discussion is limited to SICO stockholders who receive shares of A. O. Smith Class A common stock and A. O. Smith common stock in the merger and who hold SICO common stock as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all United States federal income tax considerations that may be relevant to a particular holder in light of that holder’s particular circumstances. This discussion also does not consider any specific facts or circumstances that may be relevant to holders subject to special rules under the United States federal income tax laws, including, without limitation, holders who are not United States persons, United States expatriates or former long-term residents, holders whose functional currency is not the United States dollar, partnerships and other pass-through entities, real estate investment trusts, regulated investment companies, “controlled foreign corporations,” “passive foreign investment companies,” “foreign personal holding companies,” corporations that accumulate earnings to avoid United States federal income tax, banks, financial institutions, insurance companies, brokers, dealers or traders in securities, commodities or currencies, tax-exempt organizations, tax-qualified retirement plans, persons subject to the alternative minimum tax, persons holding SICO common stock, A. O. Smith Class A common stock or A. O. Smith common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment, persons who hold SICO common stock, or receive A. O. Smith Class A common stock or A. O. Smith common stock in compensatory transactions, or persons deemed to sell the units under the constructive sale provisions of the Code.

THIS DISCUSSION IS A GENERAL SUMMARY AND DOES NOT PURPORT TO BE A COMPREHENSIVE ANALYSIS OR DESCRIPTION OF ALL POTENTIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER. SICO STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE PARTICULAR UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO THEM OF THE MERGER, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER ANY STATE, LOCAL OR FOREIGN TAX LAWS, THE FEDERAL ESTATE OR GIFT TAX LAWS, AND ANY OTHER UNITED STATES FEDERAL TAX LAWS.

Definition of United States Person

This discussion is limited to SICO stockholders who are United States persons. A United States person is any of the following:

•

an individual citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

112

•

an estate the income of which is subject to United States federal income tax regardless of its source; or

•

a trust that (a) is subject to the primary supervision of a United States court and in which one or more United States persons has the authority to control all substantial decisions or (b) has validly elected to be treated as a United States person for United States federal income tax purposes.

If a partnership (or other entity taxed as a partnership for United States federal income tax purposes) holds SICO common stock or will hold shares of A. O. Smith Class A common stock or A. O. Smith common stock, the tax treatment of a partner in the partnership generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, such partnerships and partners in such partnerships are urged to consult their tax advisors regarding the specific United States federal income tax consequences to them.

Material Tax Consequences of Merger

A. O. Smith and SICO intend that the merger will qualify as a tax-free reorganization for United States federal income tax purposes. Pursuant to the Merger Agreement, A. O. Smith’s and SICO’s obligations to effect the merger are conditioned on the receipt of the IRS Letter Ruling to the effect that for United States federal income tax purposes, the merger will constitute a reorganization within the meaning of Section 368(a) of the Code.

Assuming the merger is treated as a reorganization within the meaning of Section 368(a) of the Code, the merger will have the following United States federal income tax consequences:

•

A SICO stockholder will not recognize any gain or loss upon the receipt of shares of A. O. Smith Class A common stock and A. O. Smith common stock in exchange for the stockholder’s SICO common stock, except that gain or loss will be recognized on the receipt of cash instead of a fractional share of A. O. Smith Class A common stock or A. O. Smith common stock. In addition, payments to SICO stockholders for SICO tax benefits, as described below, will be taxable when paid. If a SICO stockholder receives cash instead of a fractional share of A. O. Smith Class A common stock or A. O. Smith common stock, the stockholder will be required to recognize gain or loss, measured by the difference between the amount of cash received and the portion of such SICO stockholder’s tax basis in his SICO common stock allocable to that fractional share of A. O. Smith Class A common stock or A. O. Smith common stock. This gain or loss will be a capital gain or loss and will be a long-term capital gain or loss if the holding period for the SICO common stock so exchanged is more than one year as of the effective time of the merger;

•

A SICO stockholder will have a tax basis in the A. O. Smith Class A common stock and A. O. Smith common stock received in the merger equal to (a) the tax basis of the SICO common stock surrendered by that stockholder in the merger, reduced by (b) any tax basis of the SICO common stock surrendered that is allocable to a fractional share of A. O. Smith Class A common stock or A. O. Smith common stock for which cash is received;

•

The holding period of the shares of A. O. Smith Class A common stock and A. O. Smith common stock received by a SICO stockholder in the merger will include the holding period of the shares of SICO common stock exchanged therefor, assuming the SICO common stock is held as a capital asset; and

•

In the case of a SICO stockholder that holds shares of SICO common stock with differing tax bases, or differing holding periods, Treasury Regulations provide guidance on how such stockholder may allocate his or her tax basis to shares of A. O. Smith Class A common stock and A. O. Smith common stock received in the merger. SICO stockholders that hold multiple blocks of SICO common stock are urged to consult their tax advisors regarding the proper allocation of their basis among and holding periods to shares of A. O. Smith Class A common stock and A. O. Smith common stock received in the merger.

113

Pursuant to the Merger Agreement, A. O. Smith will pay to the SICO stockholders an amount equal to the benefit derived by A. O. Smith from (a) carry-forwards of losses, deductions and other items of SICO and (b) amounts credited against tax of A. O. Smith or any of its subsidiaries attributable to SICO for periods before the closing date. A. O. Smith will also pay to the SICO stockholders any tax refunds of MergerCo that are received by A. O. Smith or its subsidiaries that relate to periods before the closing date. Payments, if any, to the SICO stockholders by A. O. Smith from such credits, refunds, carry forwards of losses, deductions and the other items of SICO will be taxable when paid to the SICO stockholders.

The IRS Letter Ruling will be based on certain representations as to factual matters made by SICO, A. O. Smith and MergerCo as of the time the transactions are consummated. If any such representations are inaccurate, incomplete or untrue in any material respect as of the effective time of the merger, the tax consequences of the merger and related transactions could differ materially from those described above.

Reporting Requirements

A “significant holder” of SICO stock will be required to retain records pertaining to the merger and will be required to file with such holder’s United States federal income tax return for the year in which the merger takes place a statement setting forth facts relating to the merger, including:

•

the names and employer identification numbers of all of the parties to the merger;

•

the date of the merger; and

•

the fair market value, determined immediately before the exchange of all of the SICO common stock held by such significant holder that is transferred in the transaction and such significant holder’s basis, determined immediately before the exchange, in the SICO common stock.

A “significant holder” is a SICO stockholder if, immediately prior to the exchange, such holder:

•

owned at least 5% (by vote or value) of the total outstanding stock of SICO; or

•

owned securities in SICO with a basis of $1,000,000 or more.

Information Reporting and Backup Withholding

A SICO stockholder may be subject to information reporting and backup withholding in connection with any cash payments made in connection with the merger, unless such stockholder provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded or credited against the stockholder’s United States federal income tax liability, provided the required information is timely furnished to the IRS.

The foregoing discussion of the material United States federal income tax consequences of the merger is not intended to be legal or tax advice to any particular SICO stockholder. Tax matters regarding the merger are complicated, and the tax consequences of the merger to any particular SICO stockholder will depend on that stockholder’s particular circumstances. SICO stockholders should consult their own tax advisors regarding the specific tax consequences of the merger, including tax return reporting requirements, the applicability of federal, state, local and foreign tax laws and the effect of any proposed change in the tax laws.

If at any time A. O. Smith pays a distribution of shares of A. O. Smith Class A common stock or A. O. Smith common stock, such share distribution may be declared and distributed only as follows:

•

Shares of either the A. O. Smith Class A common stock or the A. O.

•

Subject to any limitations under the laws of the State of Delaware, shares of the first class may be distributed on shares of the second class; provided that A. O. Smith declares and pays a simultaneous distribution of shares of the first class to holders of shares of the first class, which simultaneous distribution shall consist of a number of shares of the first class equal, on a per share basis, to the number of shares of the first class which are distributed to holders of the second class.

Smith Class A common stock and A. O. Smith common stock, the holders of A. O.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS OF SICO

After the Spin-Off, SICO’s only significant asset is its shares of A. O. Smith Class A common stock and A. O. Smith common stock, which in the aggregate represent a control position in A. O. Smith. SICO does not have any other assets or liabilities, except for certain SICO tax benefit items and SICO’s rights and obligations under the Merger Agreement. A. O. Smith management’s discussion and analysis of financial condition and results of operation for A. O. Smith is set forth in the sections titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the A. O. Smith Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which sections are incorporated herein by reference. The differences between the consolidated financial data for A. O. Smith and the consolidated financial data for SICO arise principally as a result of the minority interest in A. O. Smith held by the A. O. Smith stockholders other than SICO. The SICO balance sheet includes the consolidated assets and liabilities of A. O. Smith and a minority interest representing the proportionate interest of the non-SICO stockholders of A. O. Smith in the stockholders’ equity of A. O. Smith. The SICO statement of earnings equals the A. O. Smith consolidated statement of earnings with a deduction of a minority interest equal to the pro rata share of the earnings allocable to the non-SICO stockholders of A. O. Smith. The minority interest included in the SICO balance sheet is $560.8 million, $515.0 million and $469.8 million as of September 30, 2008, December 31, 2007 and December 31, 2006, respectively. The minority interest included in the SICO statement of earnings is $51.1 million for the nine months ended September 30, 2008 and $60.4 million, $52.3 million and $31.5 million for the years ended December 31, 2007, 2006 and 2005, respectively.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Smith Investment Company

We have audited the accompanying consolidated balance sheets of Smith Investment Company as of December 31, 2007 and 2006, and the related consolidated statements of earnings, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Smith Investment Company and at December 31, 2007 and 2006, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Notes 1, 11 and 12 to the financial statements, in 2007 the Company changed its method of accounting for uncertainty in income taxes, and in 2006 the Company changed its method of accounting for stock-based compensation and pension and other post-retirement benefits.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	Organization and Significant Accounting Policies

Organization. Smith Investment Company (the company) is a holding company for its ownership of A. O. Smith Corporation (A. O. Smith) and its wholly-owned subsidiaries, Berlin Industries, Inc. (Berlin) and Central States Distribution Service, Inc. (CSDS). A. O. Smith is a manufacturer serving customers worldwide. A. O. Smith’s major product lines include residential and commercial gas and electric water heating equipment, fractional horsepower alternating current, direct current, and hermetic electric motors and multicolor printing. Products are manufactured and marketed primarily in North America and China. Water heaters are sold through both wholesale and retail channels to plumbing wholesalers and retail outlets. Electric motors are sold principally to original equipment manufacturers and distributors. Berlin sells multicolor printing principally to direct mail and other advertisers, and CSDS provides warehousing and distribution services primarily to consumer product manufacturers. Throughout these consolidated financial statements, the “company” refers to the operations of its wholly-owned subsidiaries, Berlin and CSDS, and its controlled subsidiary, A. O. Smith.

Consolidation. The consolidated financial statements include the accounts of the company, its wholly-owned subsidiaries, and its controlled subsidiaries after elimination of intercompany transactions.

Use of estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements and notes. Actual results could differ from those estimates.

Fair value of financial instruments. The carrying amounts of cash and cash equivalents, trade receivables, trade payables and notes payable approximated fair value as of December 31, 2007 and 2006, due to the short maturities of these instruments. The carrying amount of long-term debt approximated fair value as of December 31, 2007 and 2006, based on current rates offered to the company for debt with the same or similar maturities. The fair values of derivative financial instruments are discussed later in this footnote.

Foreign currency translation. For all subsidiaries outside the United States, with the exception of all Mexican operations and two of the Chinese operations of A. O. Smith’s Electrical Products segment, the company uses the local currency as the functional currency. For those operations using a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at weighted-average exchange rates. The resulting translation adjustments are recorded as a separate component of stockholders’ equity. The Mexican operations and two of the Chinese operations of the company’s Electrical Products segment use the U.S. dollar as the functional currency as such operations are a direct and integral component of the company’s U.S. operations. Gains and losses from foreign currency transactions are included in net earnings.

Cash and cash equivalents. The company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Trade receivables and allowance for doubtful accounts. The company carries its trade receivables at their face amount less an allowance for doubtful accounts. On a periodic basis, the company evaluates its trade receivables and establishes the allowance for doubtful accounts based on a combination of specific customer circumstances, credit conditions, and its history of write-offs and collections. Trade receivables are written off after all collection efforts have been exhausted. The company does not require collateral as security for trade receivables.

Inventory valuation. Inventories are carried at lower of cost or market. Cost is determined on the last-in, first-out (LIFO) method for substantially all domestic inventories, which comprise 82 percent and 85 percent of the company’s total inventory at December 31, 2007 and 2006, respectively. Inventories of foreign and certain domestic subsidiaries and supplies are determined using the first-in, first-out (FIFO) method.

F-8

Property, plant and equipment. Property, plant and equipment are stated at cost. Depreciation is computed primarily by the straight-line method. The estimated service lives used to compute depreciation are generally 25 to 50 years for buildings and improvements, 3 to 20 years for equipment and 3 to 7 years for software. Maintenance and repair costs are expensed as incurred.

Goodwill and other intangibles. Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment on an annual basis. Intangible assets of $78.8 million including $32.1 million with an indefinite life were recorded as part of the GSW Inc (GSW) acquisition (see Note 2) by combined subsidiary. Indefinite-lived assets totaled $38.0 million and $39.0 million at December 31, 2007 and 2006, respectively. Separable intangible assets primarily comprised of customer relationships that are not deemed to have an indefinite life are amortized on a straight-line basis over their estimated useful lives which range from 10 to 25 years. Amortization of $4.5 million and $2.9 million was recorded in 2007 and 2006, respectively. The 2005 amount was not significant. In the future, amortization should approximate $4.1 million annually and the intangible assets will be amortized over a weighted average period of 16 years. Total accumulated amortization at December 31, 2007 and 2006 was $9.3 million and $4.8 million, respectively.

Impairment of long-lived and amortizable intangible assets. Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets. Such analyses necessarily involve significant judgment.

Derivative instruments. Statement of Financial Accounting Standards (SFAS) No. 133, as amended, requires that all derivative instruments be recorded on the balance sheet at fair value and establishes criteria for designation and effectiveness of the hedging relationships. Any fair value changes are recorded in net earnings or other comprehensive earnings.

A. O. Smith utilizes certain derivative instruments to enhance its ability to manage currency and interest rate exposures as well as raw materials price risks. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. A. O. Smith does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform.

Commodity Futures Contracts

In addition to entering into supply arrangements in the normal course of business, A. O. Smith also enters into futures contracts to fix the cost of certain raw material purchases, principally copper and aluminum, with the objective of minimizing changes in cost due to market price fluctuations.

The commodity futures contracts are designated and accounted for as cash flow hedges of a forecasted transaction. Derivative commodity liabilities of $3.5 million are recorded in accrued liabilities as of December 31, 2007. Derivative commodity assets of $14.8 million were recorded in other current assets as of December 31, 2006. The value of the effective portion of the contracts of $(2.0) million and $9.3 million as of December 31, 2007 and 2006, respectively, was recorded in accumulated other comprehensive loss, net of tax, and reclassified into cost of products sold in the period in which the underlying transaction was recorded in earnings. Ineffective portions of the commodity hedges are recorded in earnings in the period in which the ineffectiveness occurs. The impact of hedge ineffectiveness on earnings was not material in 2007, 2006 and 2005.

F-9

Foreign Currency Forward Contracts

A. O. Smith is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. A. O. Smith utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Contracts typically have maturities of one year or less. Principal currencies include the Mexican peso, Chinese renminbi, Canadian dollar and Euro.

Forward contracts are designated and accounted for as cash flow hedges of a forecasted transaction. Derivative currency assets of $2.9 million and $2.6 million as of December 31, 2007 and 2006, respectively, were recorded in other current assets. Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be perfectly effective.

The majority of the amounts in accumulated other comprehensive loss for cash flow hedges is expected to be reclassified into earnings within one year.

The following table summarizes, by currency, the contractual amounts of A. O. Smith’s foreign currency forward contracts.


	2007				2006
December 31 (dollars in millions)	Buy		Sell		Buy		Sell
Euro	$	5.5	$	2.2	$	5.4	$	2.2
Canadian dollar		—		24.1		—		3.0
Hungarian forint		1.5		—		0.4		—
Chinese renminbi		32.5		—		—		—
Mexican peso		85.5		—		95.7		—

Total	$	125.0	$	26.3	$	101.5	$	5.2

The forward contracts in place at December 31, 2007 and 2006, amounted to approximately 60 percent and 80 percent, respectively, of A. O. Smith’s anticipated subsequent year exposure for those currencies hedged.

Interest Rate Swap Agreement

A. O. Smith is exposed to interest rate risk as a result of its floating rate borrowings under its revolving credit facility. The company uses interest rate swaps to manage this risk. As of December 31, 2007, A. O. Smith had one interest rate swap outstanding in the amount of $25 million that expires in November 2010.

The interest rate swap is designated and accounted for as a cash flow hedge of floating rate debt. A derivative interest rate liability of $0.7 million as of December 31, 2007 and a $0.1 derivative interest rate asset as of December 31, 2006 are recorded in accrued liabilities and other current assets, respectively. Gains and losses on this instrument are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the statement of earnings. The assessment of effectiveness for the interest rate swap is based on changes in floating rate interest rates. This swap has been determined to be perfectly effective.

Revenue recognition. The company recognizes revenue upon transfer of title, which occurs upon shipment of the product to the customer except for certain export sales where transfer of title occurs when the product reaches the customer destination.

F-10

Contracts and customer purchase orders are used to determine the existence of a sales arrangement. Shipping documents are used to verify shipment. The company assesses whether the selling price is fixed or determinable based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. The company assesses collectibility based on the creditworthiness of the customer as determined by credit checks and analysis, as well as the customer’s payment history.

Accruals for customer returns for defective product are based on historical experience with similar types of sales. Accruals for rebates and incentives are based on pricing agreements and are tied to sales volume. Changes in such accruals may be required if future returns differ from historical experience or if actual sales volume differs from estimated sales volume. Rebates and incentives are recognized as a reduction of sales.

Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold.

Minority interest. The company owns 8,067,252 shares of Class A common stock and 1,559,076 shares of common stock of A. O. Smith, representing approximately 98% and 7%, respectively, of the outstanding shares. As of December 31, 2007, the shares owned by the company represented a 32.0% economic ownership and a 78.8% voting control of A. O. Smith. The company’s minority interest in the consolidated statements of earnings represents the minority stockholders’ share of the net earnings of A. O. Smith. The minority interests in the consolidated balance sheets reflect the ownership by the minority stockholders of the total stockholders’ equity of A. O. Smith.

The effects of A. O. Smith’s issuance and repurchase of shares on the company’s proportionate share of A. O. Smith earnings is not recorded through earnings. Such impacts are shown on the Statement of Stockholders’ Equity as “Effects of A. O. Smith Corporation stock option, stock compensation and stock repurchase activities.”

Advertising. Advertising costs are charged to operations as incurred and amounted to $38.0, $30.5, and $24.4 million during 2007, 2006 and 2005, respectively.

Research and development. Research and development costs are charged to operations as incurred and amounted to $47.8, $42.3 and $36.0 million during 2007, 2006 and 2005, respectively.

Product warranties. Most of A. O. Smith’s products carry warranties that generally range from one to ten years and are based on terms that are generally accepted in the market. A. O. Smith records a liability for the expected cost of warranty-related claims at the time of sale. The allocation of our warranty liability between current and long-term is based on expected warranty claims to be paid in the next year as determined by historical product failure rates.

The following table presents A. O. Smith’s product warranty liability activity in 2007 and 2006:


Years ended December 31 (dollars in millions)	2007			2006
Balance at beginning of year	$	98.7		$	52.4
GSW acquisition		5.0			40.6
Expense		54.8			54.3
Claims settled		(53.0	)		(48.6	)

Balance at end of year	$	105.5		$	98.7

Environmental costs. The company accrues for losses associated with environmental obligations when such losses are probable and reasonably estimable. Costs of estimated future expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded as assets when their receipt is considered probable. The accruals are adjusted as facts and circumstances change.

F-11

Stock-based compensation. Effective January 1, 2006, A. O. Smith adopted SFAS No. 123(R), “Share-Based Payment” (SFAS 123(R)), using the modified-prospective transition method. Under that method compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date. SFAS 123(R) had no impact on A. O. Smith’s financial position, statement of operations or cash flows at the date of adoption. SFAS 123(R) requires measurement of the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award at the date of grant. Compensation cost is recognized using the straight-line method over the vesting period of the award. SFAS 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under prior literature. Excess tax deductions of $4.8 million and $4.2 million were recognized as a financing cash flow in 2007 and 2006, respectively. This requirement reduced net operating cash flows and increased net financing cash flows in periods after adoption. The amount of operating cash flows recognized for such excess tax deductions was $4.5 million in 2005. A. O. Smith cannot estimate what those amounts will be in the future because they depend on, among other things, when employees exercise stock options.

Prior to the adoption of SFAS 123(R), A. O. Smith followed the disclosure requirements of SFAS No. 123, “Accounting for Stock-Based Compensation,” which encouraged, but did not require companies to record compensation cost for stock-based employee compensation plans at fair value. Prior to the adoption of SFAS 123(R), A. O. Smith accounted for share-based compensation in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. Accordingly, because the number of shares were fixed and the exercise price of the stock options equaled the market price of the underlying stock on the date of grant, no compensation expense was recognized. Had compensation cost been determined based upon the fair value at the grant date for stock option awards under the plan based on the provisions of SFAS No. 123, the company’s pro forma earnings and earnings per share would have been as follows:


Year ended December 31 (dollars in millions)	2005
Earnings:
As reported	$	9.7
Add: Stock-based employee compensation expense recorded for restricted stock awards, net of tax		2.7
Deduct: Total stock-based employee compensation expense determined under fair value based method, net of tax		(3.8	)
Minority interest in net additional compensation expense		0.7
Pro forma	$	9.3
Earnings per share:
As reported:
Basic and diluted	$	2.93
Pro forma:
Basic and diluted	$	2.80

Except as mentioned above, there is no other impact of adopting SFAS 123 (R) versus SFAS No. 123.

Earnings per share of common stock. The numerator for the calculation of basic and diluted earnings per share is net earnings. The denominator for basic and diluted earnings per share is the weighted average shares outstanding. The company has no dilutive stock options, restricted stock or other share equivalents; therefore, basic and diluted earnings per share are equal. Earnings per share is calculated based on net earnings rounded to the nearest thousand, which was $30.370 million, $22.678 million and $9.721 million for the years ended December 31, 2007, 2006 and 2005, respectively.

Restricted marketable securities. As described in Note 2, A. O. Smith acquired GSW in 2006. GSW operated a captive insurance company to provide product liability and general liability insurance to its subsidiary American Water Heater Co. (American). A. O. Smith decided to cover American’s prospective liability exposures with its existing insurance programs and all product liability claims for events which occurred prior to July 1, 2006 will be financed by the captive. The reinsurance company restricts the amount of capital which must be maintained by the captive and this restricted amount is $38.9 million and $37.7 million at December 31, 2007 and 2006, respectively. The $38.9 million and $37.7 million of restricted money market instruments are included in other assets on the company’s balance sheet at December 31, 2007 and 2006, respectively. The cost of the money market instruments approximates fair value.

Recent accounting pronouncements. In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 also establishes a fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability. SFAS 157 will be effective for the company beginning in 2008. The company is assessing the potential impact that the adoption of SFAS 157 will have on its consolidated financial condition, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141 (R), “Business Combinations.” This statement will apply to acquisitions made by the company after January 1, 2009. The company is currently evaluating the impact of this statement on its overall financial position.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements,” which establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. This statement is effective for the company after January 1, 2009. The company is currently evaluating the impact of this statement on its overall financial position.

In March 2008 the FASB issued SFAS No. 161, “Disclosures About Derivative Instruments And Hedging Activities—An Amendment Of FASB Statement No. 133,” which changes the disclosure requirements for derivative instruments and hedging activities. It is intended to enhance the current disclosure framework in FASB No. 133. This statement is effective for the company in the first quarter of 2009 and the company does not expect the adoption of this statement to have an impact on its overall financial position.

2.	Acquisitions

On April 3, 2006, A. O. Smith acquired GSW, a publicly traded Canadian-based manufacturer which operated in two business segments: water heaters and building products. The water heating segment manufactures and markets water heaters sold in the U.S. and Canada through its American and GSW Water Heater subsidiaries. The addition of GSW to A. O. Smith’s existing water heater operations expands its share of the growing retail channel of the U.S. residential water heater market segment as well as increases its presence in the Canadian residential water heater market segment. On December 19, 2006, the company sold the building products business for $11.4 million and in 2007, recorded a reduction in sales proceeds of $0.4 million associated with a working capital adjustment. For accounting purposes, the operations of the building products business are reported as a discontinued operation.

The aggregate purchase price, net of $39.3 million of cash acquired, was $307.7 million. This was comprised of $339.3 million for the outstanding stock and $7.7 million of acquisition costs principally incurred in 2005. In addition, $36.9 million of payments were made for change in control provisions and tax liabilities assumed.

F-13

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition as finalized in 2007.

The pro forma results have been prepared for informational purposes only and include adjustments for depreciation expense of acquired plant and equipment, amortization of intangible assets other than goodwill and trademarks, increased interest expense on acquisition debt, and certain other adjustments, together with related income tax effects of such adjustments. Anticipated efficiencies from the consolidation of manufacturing and commercial activities and anticipated lower material costs related to the consolidation of purchasing have been excluded from the pro forma operating results. These pro forma results do not purport to be indicative of the results of operations that would have occurred had the purchase been made as of the beginning of the period presented or of the results of operations that may occur in the future.

In November 2005, A. O. Smith acquired Yueyang Zhongmin Special Electrical Machinery Co., Ltd. (Yueyang), a manufacturer of hermetic motors located in Yueyang City, Hunan Province, China. The total cost

F-14

of the acquisition was $17.9 million including fixed future payments of $1.4 million which were made in 2006 as well as potential future payments not to exceed $1.7 million subject to reductions for claims the company may make if there are any breaches of the representations and warranties made by the selling shareholders under the acquisition agreement. $1.2 million was paid to the sellers in 2007. The remaining $0.5 million is currently in dispute. This cost exceeded the fair value of the acquired net assets by $10.6 million, which was recorded as goodwill in the Electrical Products segment.

The purchase price for the Yueyang acquisition was allocated to the assets acquired and liabilities assumed based upon estimates of its respective fair value at the date of acquisition. The operating results have been included in the company’s consolidated financial statements since the date of acquisition.

Stock Based Compensation

A. O. Smith adopted the A. O. Smith Combined Incentive Compensation Plan (the “plan”) effective January 1, 2007. The plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by shareholders in 2002.

The weighted-average fair value per option at the date of grant during 2007, 2006 and 2005, using the Black-Scholes option-pricing model, was $14.43, $12.94 and $10.82, respectively. Assumptions were as follows:


	2007		2006		2005
Expected life (years)	6.5		6.4		6.6
Risk-free interest rate	4.7	%	4.4	%	4.2	%
Dividend yield	1.8	%	2.2	%	2.2	%
Expected volatility	36.0	%	38.0	%	39.9	%

The expected life is based on historical exercise behavior and the projected exercise of unexercised stock options. The risk free interest rate is based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected life of the option. The expected dividend yield is based on the expected annual dividends divided by the grant date market value of the common stock of A. O. Smith. The expected volatility is based on the historical volatility of the common stock of A. O. Smith.

Restricted stock and share units

Participants may also be awarded shares of restricted stock or share units under the plan. The company granted 68,600, 21,000, and 120,000 share units under the plan in 2007, 2006 and 2005, respectively. The company granted 15,000 shares of restricted stock in 2005. The restricted stock and share units were valued at $2.7, $0.8 and $3.9 million at the date of issuance in 2007, 2006 and 2005, respectively, and will be recognized as compensation expense ratably over the three-year vesting period. Compensation expense of $2.9, $2.3 and $4.3 million was recognized in 2007, 2006 and 2005, respectively. Share based compensation expense in 2007 and 2005 included $0.5 million and $1.8 million of expense, respectively, associated with the accelerated vesting of restricted stock and share unit awards for certain executives who retired or were retirement eligible in those years.

A summary of restricted stock and share unit activity under the plan is as follows:


	Number of Units		Weighted-Average Grant Date Value
Outstanding at January 1, 2007	267,835		$	28.03
Granted	68,600			38.87
Vested	(121,835	)		25.52
Terminated	(2,100	)		26.81

Outstanding at December 31, 2007	212,500		$	32.91

Total compensation expense for restricted stock and share units not yet recognized is $2.3 million at December 31, 2007. The weighted average period over which the expense is expected to be recognized is one year.

Pension and Other Post-Retirement Benefits

A. O. Smith provides retirement benefits for all United States employees including benefits for employees of previously owned businesses which were earned up to the date of sale. The company also has several foreign pension plans, none of which are material to the company’s financial position.

The company has defined-contribution profit sharing and retirement plans covering the majority of its salaried nonunion employees and certain nonunion hourly employees which provides for annual company contributions of 30 percent to 140 percent of qualifying contributions made by participating employees. The amount of the company’s contribution in excess of 30 percent is dependent upon the company’s individual operating unit profitability. The company also has defined-contribution plans for certain hourly employees which provide for annual matching company contributions.

F-22

The company has several unfunded defined-benefit post-retirement plans covering certain hourly and salaried employees that provide medical and life insurance benefits from retirement to death. Certain hourly employees retiring after January 1, 1996, are subject to a maximum annual benefit and salaried employees hired after December 31, 1993, are not eligible for post-retirement medical benefits.

On December 31, 2006, the company adopted SFAS No. 158, “Employer’s Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R).” SFAS 158 requires that the company recognize the overfunded or underfunded status of its defined benefit and retiree medical plans as an asset or liability in the balance sheet with changes in the funded status recognized through comprehensive income in the year in which they occur. The impact of adoption was a one-time-before-tax charge to accumulated other comprehensive loss of $28.2 million.

The estimated net actuarial loss and prior service cost for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2008 are $7.7 million and $0.5 million, respectively. The estimated net actuarial loss and prior year service cost for the post-retirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2008 are each less than $0.1 million. As permitted under paragraph 26 of FASB Statement No. 87 and paragraph 53 of Statement No. 106, the amortization of any prior service cost is determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the Plan.

The 2007 and 2006 after tax adjustments for additional minimum pension liability resulted in other comprehensive earnings of $33.8 million and $15.0 million, respectively.

Assumptions

Actuarial assumptions used to determine benefit obligations at December 31 are as follows:


	Pension Benefits				Post-retirement Benefits
	2007		2006		2007		2006
Discount rate	6.5	%	5.9	%	6.5	%	5.9	%
Average salary increases	4.0	%	4.0	%	4.0	%`	4.0	%

F-24

Actuarial assumptions used to determine net periodic benefit cost for the year ended December 31 are as follows:


	Pension Benefits						Post-retirement Benefits
Years ended December 31	2007		2006		2005		2007		2006		2005
Discount rate	5.90	%	5.75	%	6.00	%	5.90	%	5.75	%	6.00	%
Expected long-term return on plan assets	8.75	%	8.75	%	8.75	%	n/a		n/a		n/a
Rate of compensation increase	4.00	%	4.00	%	4.00	%	4.00	%	4.00	%	4.00	%

In developing the expected long-term rate of return assumption, the company evaluated its pension plan’s target and actual asset allocation and historical long-term rates of return of equity and bond indices. The company also considered its pension plan’s historical 10- and 25-year compounded annualized returns of 8.6 percent and 12.1 percent, respectively.

Assumed health care cost trend rates

Assumed health care cost trend rates as of December 31 are as follows:


	2007		2006
For participants under age 66:
Health care cost trend rate assumed for next year	10.00	%	10.00	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	5.00	%	5.00	%
Year that the rate reaches the ultimate trend rate	2013		2012
For participants over age 65:
Health care cost trend rate	6.00	%	6.00	%

A one-percentage-point change in the assumed health care cost trend rates would not result in a material impact on the company’s consolidated financial statements.

Plan Assets

Plan assets relate to the those plans sponsored by A. O. Smith. A. O. Smith’s pension plan weighted asset allocations as of December 31 by asset category are as follows:


	2007		2006
Asset Category
Equity securities	71	%	70	%
Debt securities	24		24
Private equity	4		3
Other	1		3

	100	%	100	%

A. O. Smith’s target allocation to equity managers is between 60 to 70 percent with the remainder allocated primarily to bond managers and a small allocation to private equity managers. The company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

There is no A. O. Smith stock included in plan assets at December 31, 2007 and 2006.

Cash Flows

A. O. Smith is not required to contribute to its pension plans. In 2007, A. O. Smith made contributions of $16 million and may elect to make a contribution during 2008.

F-26

No provision for U.S. income taxes or foreign withholding taxes has been made on the undistributed earnings of foreign subsidiaries as such earnings are considered to be permanently invested. At December 31, 2007, the undistributed earnings amounted to $184.5 million. Determination of the amount of unrecognized deferred tax liability on the undistributed earnings is not practicable. In addition, no provision or benefits for U.S. income taxes have been made on foreign currency translation gains or losses.

The tax effects of temporary differences of assets and liabilities between income tax and financial reporting are as follows:


	2007					2006

Net (liability) asset	$	3.3		$	7.4

A. O. Smith has foreign net operating loss carryovers with tax benefits of $3.9 million. Of the $3.9 million of tax benefits, $3.6 million have an unlimited carryover period and $0.3 million expire in 2008. Based on future realizability, a valuation allowance of $3.9 million has been established against the foreign net operating loss carryover tax benefits.

The company also has U.S. net operating loss carryovers having a tax value of $3.3 million, U.S. tax credits carryovers of $0.2 million, state and local net operating loss carryovers having a tax value of $5.6 million and state and local tax credit carryovers of $1.3 million. These carryovers expire between 2008 and 2027. Based on future realizability, a valuation allowance of $0.6 million has been established against the state and local carryover tax benefits.

During 2007 and 2006, the valuation allowance was decreased and goodwill decreased by $1.3 million and $1.0 million, respectively, to reflect expected utilization of tax benefits previously acquired with the State Industries, Inc. acquisition by A. O. Smith in 2001. Also, in 2007 the valuation allowance was increased by $0.7 million for the current year tax benefits of foreign loss carryovers that are not expected to be utilized and decreased by $0.2 million to reflect expiration of foreign net operating losses. The valuation allowance was also

F-27

decreased by $2.0 million in 2006 to reflect expiration of federal capital loss carryovers previously acquired with the State Industries, Inc. acquisition and by $0.3 million to reflect expiration of foreign net operating loss carryovers.

In China, foreign investment enterprises engaged in manufacturing activities are granted favorable tax treatment during start-up periods. The enterprises are granted a two-year tax exemption and a three-year 50% tax rate reduction beginning with the enterprise’s first profit making year. In 2007 three of the company’s China subsidiaries benefited from the favorable tax treatment. The consolidated earnings would have been $0.34 per share lower without the tax holiday.

The company adopted the provisions of FIN 48 on January 1, 2007. There was no cumulative effect of adoption recorded to retained earnings. A reconciliation of the beginning and ending amount of unrecognized benefits is as follows:


(Dollars in millions)
Balance at January 1, 2007	$	7.6
Additions based on tax positions related to the current year		0.5
Additions for tax positions of prior years		—
Reductions for tax positions of prior years		(3.3	)
Settlements		—

Balance at December 31, 2007	$	4.8

The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate of $3.7 million. The company recognizes potential interest and penalties related to unrecognized tax benefits as a component of tax expense. At January 1, 2007, there was $0.8 million of interest and penalties accrued. The amount was reduced to $0.4 million during 2007. It is not anticipated there will be a significant change in the total amount of unrecognized tax benefits in the next 12 months. The company’s U.S. federal tax returns for 2005-2007 are subject to audit. The company is subject to state and local audits for tax years 2003-2007. The company is subject to non-U.S. income tax examinations for years 2001-2007.

Commitments and Contingencies

A. O. Smith is a potentially responsible party in eight judicial and administrative proceedings initiated on behalf of various state and federal regulatory agencies seeking to clean up sites which have been environmentally impacted and to recover costs they have incurred or will incur as to the sites.

A. O. Smith has established reserves for the sites and insurance proceeds and potential recovery from third parties are available to cover a portion of the company’s potential liability. The company believes that any environmental claims for these sites in excess of reserves, insurance proceeds and indemnified amounts will not have a material effect on its financial position or results of operations.

A. O. Smith or its subsidiaries have been named as a co-defendant in lawsuits alleging personal injury as a result of exposure to asbestos integrated into certain of A. O. Smith’s or its subsidiaries’ products or premises. A. O. Smith and its subsidiaries have never manufactured asbestos. As of December 31, 2007, A. O. Smith and its subsidiaries are defendants in lawsuits involving claims by approximately 66,072 plaintiffs. A. O. Smith and its subsidiaries have made no payment in a substantial majority of the cases closed to date. The remainder of the resolved cases have settled for amounts that are not material to the company, and the costs of defense and settlements have been supported in part by insurance.

A. O. Smith has been named as a co-defendant in lawsuits alleging manganese-induced illness involving claims by approximately 2,560 plaintiffs. The claimants in these lawsuits allege that exposure to manganese in welding consumables caused them to develop adverse neurological conditions, including a condition known as

F-28

manganism, and are seeking compensatory and, in many instances, punitive damages, usually for unspecified sums. A. O. Smith manufactured welding consumables from 1918 until it sold that business to another company in 1965. A. O. Smith has not been found liable in any of the lawsuits and has not paid any settlements. The costs of defense have been paid by insurance, and the company believes it has adequate insurance coverage to cover its exposure.

A. O. Smith is subject to various claims and pending lawsuits for product liability and other matters arising out of the conduct of A. O. Smith’s business. With respect to product liability claims, A. O. Smith has self-insured a portion of its product liability loss exposure for many years. A. O. Smith has established reserves which it believes are adequate to cover incurred claims. For the years ended December 31, 2007 and 2006, A. O. Smith had $125 million of product liability insurance for individual losses in excess of $5 million. A. O. Smith periodically reevaluates its exposure on claims and lawsuits and makes adjustments to its reserves as appropriate. The company believes, based on current knowledge, consultation with counsel, adequate reserves and insurance coverage that the outcome of such claims and lawsuits will not have a material adverse effect on the company’s financial position, results of operations or cash flows.

In a Form 8-K filed with the Securities and Exchange Commission on October 19, 2007, A. O. Smith disclosed an adverse verdict in a product liability lawsuit in Baldwin County, Alabama.

On February 19, 2008, all plaintiffs executed a Release, Settlement and Confidentiality Agreement (the Settlement) resolving the lawsuit in its entirety. The Settlement is subject to Baldwin County Court approval, which the company believes will be granted. As part of the Settlement, the adverse verdict will be vacated by the Baldwin County Court. The terms of the Settlement are confidential. A. O. Smith’s expense related to the Settlement is included in the reserve recorded as of December 31, 2007.

Subsequent Event (Unaudited)

On February 4, 2008, the company announced a proposal to restructure its holdings in A. O. Smith, whereby the stockholders of the company would receive direct ownership of A. O. Smith shares. Stockholders are expected to be entitled to receive 2.396 shares of A. O. Smith Class A common stock and .463 shares of A. O. Smith common stock for each share of the company’s stock they hold (i) assuming no change in the number of shares of SICO common stock issued and outstanding or in the number of shares of A. O. Smith common stock and Class A common stock held by SICO, and (ii) without regard to escrow shares, dissenting shares and fractional shares. Pursuant to the proposed transaction, the company would be merged with a newly formed subsidiary of A. O. Smith. The merger agreement was entered into on December 9, 2008 and completion of the merger is subject to shareholder approval, the receipt of a favorable ruling from the Internal Revenue Service and other conditions.

To facilitate the merger, the Parent contributed substantially all of its assets and liabilities, which included the operating businesses of Berlin and CSDS, to Smith Investment Company LLC, and then distributed to its stockholders, in a taxable spin-off transaction, the interest of the Parent in Smith Investment Company LLC. Stockholders received membership units in Smith Investment Company LLC in the spin-off transaction. The distribution occurred on January 19, 2009. The assets contributed to Smith Investment Company LLC did not include A. O. Smith stock of the Parent.

As of November 1, 2008, the company entered into an agreement to sell substantially all of the assets of CSDS for a purchase price of $6 million, subject to working capital adjustments. The company anticipates recording a gain of $3.3 million related to the sale, which is expected to close in the first quarter of 2009.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2008

(Unaudited)

1.	Basis of Presentation

Smith Investment Company (the company) is a holding company for its ownership of A. O. Smith Corporation (A. O. Smith) and its wholly-owned subsidiaries, Berlin Industries, Inc. (Berlin) and Central States Distribution Service, Inc. (CSDS). A. O. Smith is a manufacturer serving customers worldwide. A. O. Smith’s major product lines include residential and commercial gas and electric water heating equipment, fractional horsepower alternating current, direct current, and hermetic electric motors and multicolor printing. Products are manufactured and marketed primarily in North America and China. Water heaters are sold principally to original equipment manufacturers and distributors. Berlin sells multicolor printing principally to direct mail and other advertisers, and CSDS provides warehousing and distribution services primarily to consumer product manufacturers. Throughout these consolidated financial statements, the “company” refers to the operations of its wholly-owned subsidiaries, Berlin and CSDS, and its controlled subsidiary, A. O. Smith.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine-month period ended September 30, 2008 are not necessarily indicative of the results expected for the full year. It is suggested that the accompanying condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2007.

3.	Restricted Marketable Securities

A. O. Smith acquired GSW Inc. (GSW) on April 3, 2006. GSW operated a captive insurance company (Captive) to provide product liability and general liability insurance to its subsidiary American Water Heater Company (American). The company decided to cover American’s prospective liability exposures with its existing insurance programs and all product liability claims for events which occurred prior to July 1, 2006 will be financed by the Captive. The reinsurance company restricts the amount of capital which must be maintained by the Captive and this restricted amount was $27.5 million at September 30, 2008. The $27.5 million is invested in short-term securities and is included in other non-current assets on the company’s balance sheet on September 30, 2008. During the second quarter of 2008, the Captive liquidated approximately $12.0 million of short-term securities and paid the company a dividend of $12.0 million on June 1, 2008. The company used the proceeds from this dividend to pay down debt.

F-35

4.	Long-Term Debt

A. O. Smith has a $425 million multi-currency revolving credit agreement with nine banks. The facility expires in 2011 and has an accordion provision which allows it to be increased up to $500 million if certain conditions (including lender approval) are satisfied. Borrowing rates under the facility are determined by the company’s leverage ratio.

Borrowings under the bank credit lines and commercial paper borrowings are supported by the $425 million revolving credit agreement. As a result of the long-term nature of this facility, the commercial paper and credit line borrowings are classified as long-term debt.

5.	Product Warranties (dollars in millions)

A. O. Smith offers warranties on the sales of certain of its products and records an accrual for the estimated future claims. Such accruals are based upon historical experience and management’s estimate of the level of future claims.

Denominator for diluted earnings per share	3,317,066	3,317,066

8.	Stock-Based Compensation

The company’s subsidiary, A. O. Smith, adopted the A. O. Smith Combined Incentive Compensation Plan (the “plan”) effective January 1, 2007 which provides for the issuance of 1,250,000 stock options, restricted stock or share units. Additionally, any shares that would have been available for stock options, restricted stock or share units under a predecessor plan, if that plan was in effect, will be available for granting of share based awards under the plan. The number of A. O. Smith shares available for granting of options or share units at September 30, 2008 was 934,224. Upon stock option exercise, restricted stock grant, or share unit vesting and issuance, shares are issued from treasury stock of A. O. Smith.

Total stock based compensation cost recognized in the nine-month periods ended September 30, 2008 and 2007 was $4.2 million and $3.9 million, respectively.

Stock Options

The stock options granted in the nine-month periods ended September 30, 2008 and 2007, have three year pro-rata vesting from the date of grant. Stock options are issued at exercise prices equal to the fair value of A. O. Smith common stock on the date of grant. For active employees, all options granted in 2008 and 2007 expire ten years after date of grant. Options are expensed ratably over the three year vesting period. Stock option compensation cost recognized in the nine-month periods ended September 30, 2008 and 2007 was $1.5 million and $1.4 million, respectively. Included in the stock option expense for the nine-month periods ended September 30, 2008 and 2007 is expense associated with the accelerated vesting of stock option awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period.

Changes in option shares, all of which are A. O. Smith common stock, were as follows for the nine months ended September 30, 2008:


	Weighted-Avg. Per Share Exercise Price		Nine Months Ended September 30, 2008		Average Remaining Contractual Life	Aggregate Intrinsic Value (dollars in millions)
Outstanding at January 1, 2008	$	27.01	1,117,434
Granted		35.64	171,400
Exercised		26.61	(27,967	)
Terminated		35.64	(800	)

Outstanding at September 30, 2008		28.19	1,260,067		6 years	$	13.9

Exercisable at September 30, 2008	$	25.46	926,467		5 years	$	12.7

F-37

The weighted-average fair value per option at the date of grant during the nine months ended September 30, 2008 and 2007, using the Black-Scholes option-pricing model, was $11.82 and $14.43, respectively. Assumptions were as follows:


	Nine Months Ended September 30
	2008		2007
Expected life (years)	6.4		6.5
Risk-free interest rate	3.7	%	4.7	%
Dividend yield	2.0	%	1.8	%
Expected volatility	35.1	%	36.0	%

The expected life is based on historical exercise behavior and the projected exercise of unexercised stock options. The risk free interest rate is based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected life of the option. The expected dividend yield is based on the expected annual dividends divided by the grant date market value of our common stock. The expected volatility is based on the historical volatility of our common stock.

Restricted Stock and Share Units

Participants may also be awarded shares of restricted stock or share units under the plan. A. O. Smith granted 144,008 and 68,600 share units under the plan in the nine-month periods ended September 30, 2008 and 2007, respectively. Included in the grant in the nine-month period ended September 30, 2008, are share units granted on April 30, 2008 which are subject to performance conditions and vest on December 31, 2010. The ultimate number of share units that will vest will range from zero to 96,000 based on the average of the company’s annual return on equity for the eleven quarters ending December 31, 2010. Compensation expense will be recognized over the vesting period (eleven quarters) as long as achievement of the performance conditions is considered probable. The share units were valued at $4.9 million and $2.7 million at the date of issuance in 2008 and 2007, respectively, based on the company’s stock price at the date of grant, and in each case, such value will be recognized as compensation expense ratably over the three-year vesting period (except as noted above).

Share based compensation expense attributable to restricted stock and share units of $2.7 million and $2.5 million was recognized in the nine-month periods ended September 30, 2008 and 2007, respectively. Share based compensation expense recognized in the nine-month periods ended September 30, 2008 and 2007 included expense associated with accelerated vesting of share unit awards for certain employees who either are retirement eligible or will become retirement eligible during the vesting period.

A summary of restricted stock and share unit activity under the plan is as follows:


	Number of Units		Weighted-Average Grant Date Value
Outstanding at January 1, 2008	212,500		$	32.91
Granted	144,008			33.69
Vested	(5,000	)		27.58

Restructuring and Other Charges

Electrical Products Restructuring and Other Costs

In 2007, $13.6 million of expense was recognized for the full year and $1.6 million was recognized in the nine-month period ended September 30, 2007, for the continuation of domestic repositioning activities. Included in the full year amount was an asset impairment charge of $10.6 million. The majority of the domestic repositioning charges relate to the announced closure of the Scottsville, KY and Mebane, NC production facilities. The closures are expected to occur in the fourth quarter of 2008. Electrical Products is consolidating its hermetic motor assembly operations in Acuna, Mexico and Suzhou, China. An additional $7.1 million of expense was recognized in the nine-month period ended September 30, 2008.

Additionally, in the fourth quarter of 2007, Electrical Products, a segment of A. O. Smith, recognized $9.2 million of expense (of which $7.5 million is an asset impairment charge) and a $9.9 million tax benefit related to the announced closure of its Budapest, Hungary facility. The closure of its Budapest, Hungary facility resulted in certain operations being transferred to China. Production ceased in the first quarter of 2008 and the plant closed in the second quarter of 2008. An additional $0.4 million of expense associated with the plant closure was recorded in the third quarter of 2008.

The year-to-date net favorable restructuring adjustment associated with the Hungary plant closure is $1.2 million and includes a $2.9 million favorable cumulative translation adjustment recorded in the second quarter of 2008. Total pretax restructuring expense for Electrical Products for 2008 is expected to be approximately $12.0 million.

The following table presents an analysis of the company’s Electrical Products restructuring reserve as of and for the nine months ended September 30, 2008 (dollars in millions):

The company adopted SFAS 157 on January 1, 2008. SFAS 157, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. SFAS 157 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, SFAS 157 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Liabilities measured at fair value on a recurring basis are as follows (dollars in millions):


				Fair Value Measurement Using

Net derivative contracts	$	(14.0	)	$	(11.3	)	$	(2.7	)

There were no changes in our valuation techniques used to measure fair values on a recurring basis as a result of adopting SFAS 157.

Subsequent Event (Unaudited)

On February 4, 2008, the company announced a proposal to restructure its holdings in A. O. Smith, whereby the stockholders of the company would receive direct ownership of A. O. Smith shares. Stockholders are expected to be entitled to receive 2.396 shares of A. O. Smith Class A common stock and .463 shares of A. O. Smith common stock for each share of the Company’s stock they hold (i) assuming no change in the number of shares of SICO common stock issued and outstanding or in the number of shares of A. O. Smith common stock and Class A common stock held by SICO, and (ii) without regard to escrow shares, dissenting shares and fractional shares. Pursuant to the proposed transaction, the company would be merged with a newly formed subsidiary of A. O. Smith. The merger agreement was entered into on December 9, 2008 and completion of the merger is subject to shareholder approval, the receipt of a favorable ruling from the Internal Revenue Service and other conditions.

As of November 1, 2008, the Company entered into an agreement to sell substantially all of the assets of CSDS for a purchase price of $6 million, subject to working capital adjustments. The Company anticipates recording a gain of $3.3 million related to the sale, which is expected to close in the first quarter of 2009.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED

FINANCIAL INFORMATION FOR SICO

The unaudited pro forma financial information for SICO presented below consists of the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of September 30, 2008 and the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the nine months ended September 30, 2008, and the year ended December 31, 2007. The unaudited pro forma financial information for SICO presented below should be read in conjunction with the financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of SICO” appearing elsewhere in this joint proxy statement/prospectus. The unaudited pro forma financial information for SICO has been prepared giving effect to the Spin-Off and the merger as if these transactions occurred as of January 1, 2008 for the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the nine months ended September 30, 2008 and as of January 1, 2007 for the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the year ended December 31, 2007 and as of September 30, 2008 for the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of September 30, 2008.

The Unaudited Pro Forma Condensed Consolidated Balance Sheet and Statements of Operations included in this joint proxy statement/prospectus have been derived from the audited consolidated financial statements and the unaudited condensed consolidated interim financial statements of SICO included elsewhere in this joint proxy statement/prospectus and do not purport to represent what SICO’s financial position and results of operations actually would have been had the Spin-Off, the merger and related transactions occurred on the dates indicated or to project SICO’s financial performance for any future period.

In addition to being a reverse acquisition under SFAS 141(R), the merger is a common control transaction according to SFAS 160 Noncontrolling Interests in Consolidated Financial Statements an amendment of ARB No. 51 (SFAS 160). As a result, the merger will be accounted for as an equity transaction and therefore will not require purchase accounting adjustments to reflect fair value. Because A. O. Smith is the legal acquirer, the SICO shares are treated as having been converted to SICO’s ownership of A. O. Smith stock via a stock split to reflect SICO’s ownership of A. O. Smith Class A common stock and A. O. Smith common stock. Prior to the merger, SICO consolidated the financial results of A. O. Smith and presented a minority interest (referred to as a noncontrolling interest under SFAS 160). The noncontrolling interest represented the portion of A. O. Smith that SICO did not own. Under a reverse acquisition, the noncontrolling interest is eliminated from the financial statement presentation in future periods as A. O. Smith is the legal acquirer and the accounting acquiree. Although the non-SICO stockholders of A. O. Smith are not exchanging their shares in the merger, the reverse acquisition accounting requires the transaction to be presented as if an acquisition of the noncontrolling interest occurred since there is no remaining noncontrolling interest once the two companies are combined into one reporting entity.

(1)	The adjustments in this column reflect the elimination of the assets and liabilities of SICO’s wholly-owned operating subsidiaries that were contributed to SpinCo by SICO as if the contribution occurred as of September 30, 2008.

(2)	The adjustments in this column reflect the elimination of certain assets and liabilities of SICO that were contributed to SpinCo by SICO as if the contribution occurred as of September 30, 2008.

(3)

Effective January 1, 2009, SICO (as the successor company for accounting purposes) is required to adopt SFAS 160 and such adoption is required to be retroactive to prior periods presented pursuant to paragraph 5 of SFAS 160. Adjustment reflects the adoption of the pronouncement as of September 30, 2008, which results in a reclassification of the minority interest into stockholders’ equity as a noncontrolling interest.

(4)

The proforma adjustments in this column reflect the transaction as a reverse acquisition between SICO and A. O. Smith, with SICO as the accounting acquirer and A. O. Smith as the accounting acquiree. In accordance with SFAS 141(R ) and SFAS 160, the reverse acquisition is treated as an equity transaction with SICO as the successor company for accounting purposes. Since A. O. Smith is the legal acquirer, SICO’s capital stock is required to be converted to capital stock of the legal acquirer, A. O. Smith, for financial reporting purposes. The following table sets forth the adjustments required as a result of the reverse acquisition under SFAS 160:


	(A)			(B)			(C)			(D)			Net adjustment
Common stock—SICO	$	(0.3	)	$	—		$	—		$	—		$	(0.3	)

Accumulated other comprehensive loss		—			—			(67.1	)		—			(67.1	)
Treasury stock		—			(83.2	)		—			(1.3	)		(84.5	)
Noncontrolling interest		—			(560.8	)		—			—			(560.8	)

(A)

To reflect stock split such that SICO common stock is converted into its controlling interest in A. O. Smith. The adjustment converts SICO common stock into the shares of A. O. Smith Class A common stock and A. O. Smith common stock that SICO owns as of September 30, 2008.

(B)

Reflects the assumed shares issued for the acquisition of the noncontrolling interest and the 1.5228% premium to A. O. Smith shown as a reduction in the number of A. O. Smith shares owned by SICO shareholders pursuant to the Merger Agreement. This is shown in the table below.


	Class A common stock			Common stock
Shares at par value issued for the acquisition of the noncontrolling interest	$	1.1		$	22.7
Retirement of shares due to 1.5228% premium to A. O. Smith pursuant to the Merger Agreement		(0.6	)		—

Total	$	0.5		$	22.7

The adjustment also includes treasury shares at cost of $83.2 which are currently part of the A. O. Smith stockholders’ equity and eliminates the noncontrolling interest as a result of the reverse acquisition of $560.8. The difference between the consideration (i.e., shares issued/acquired) and the carrying value of the noncontrolling interest is shown as an increase to capital in excess of par of $620.8.

(C)

Reflects the accumulated other comprehensive loss related to the acquired noncontrolling interest.

(D)

Reflects the reclassification of the transaction costs, net of taxes, incurred by SICO in conjunction with the merger and Spin-Off which were previously expensed. Upon the adoption of FAS 160, such costs are shown as a component of treasury stock.

AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of December 9, 2008, is made by and among A. O. Smith Corporation, a Delaware corporation (“Parent”), SICO Acquisition, LLC, a Delaware limited liability company and a wholly owned subsidiary of Parent (“MergerCo”), Smith Investment Company, a Nevada corporation (the “Company”), and (solely for purposes of Sections 5.8, 5.11, 5.12, 5.16 and 5.18 and Article VII) Smith Investment Company LLC, a Delaware limited liability company (“SpinCo”). Capitalized terms used herein but not otherwise defined shall have the meanings set forth in Section 9.2.

RECITALS

A. The parties wish to effect a business combination through a merger of the Company with and into MergerCo (the “Merger”) on the terms and conditions set forth in this Agreement and in accordance with the Nevada Revised Statutes (the “NRS”) and the Delaware Limited Liability Company Act (the “DLLCA”).

ARTICLE II

CONVERSION OF SECURITIES;

EXCHANGE OF CERTIFICATES

2.1 Effect on Securities. As of the Effective Time, by virtue of the Merger and without any action on the part of Parent, MergerCo or the Company or the holders of any of the following securities:

(a) Each MergerCo Membership Unit issued and outstanding immediately prior to the Effective Time shall remain outstanding as one Surviving Entity Membership Unit following the Merger.

(b) Each share of Company Common Stock that is owned by the Company, by any wholly owned Subsidiary of the Company or by Parent, MergerCo or any other wholly owned Subsidiary of Parent shall automatically be canceled and retired and shall cease to exist, and no cash or other consideration shall be delivered or deliverable in exchange therefor.

(c) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.1(b) and Dissenting Shares as described in Section 2.4) (the “Company Merger Stock”) shall be converted into the right to receive (i) the number of shares of Parent Class A Common Stock equal to the Class A Exchange Ratio, (ii) the number of shares of Parent Common Stock equal to the Closing Common Exchange Ratio and (iii) the number of Escrow Shares equal to the Per Share Escrow Release Number, if any, upon release thereof pursuant to the Escrow Agreement (clause (i) and (ii), together with any cash paid in lieu of fractional shares with respect thereto in accordance with Section 2.2(i), the “Closing Merger Consideration” and clause (iii), together with any cash paid in lieu of fractional shares with respect thereto in accordance with Section 2.2(i) and the Closing Merger Consideration, the “Merger Consideration”). Upon such conversion, all such shares of Company Merger Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each Company Certificate previously evidencing such shares shall thereafter represent only the right to receive the Merger Consideration. The holders of Company Certificates previously evidencing shares of Company Merger Stock shall cease to have any rights with respect to the Company Merger Stock except as otherwise provided herein or by Law and, upon the surrender of Company Certificates in accordance with the provisions of Section 2.2, shall only represent the right to receive the Merger Consideration for their shares of Company Merger Stock.

(d) The Exchange Agent shall make all computations contemplated by this Section 2.1 of this Agreement and all such computations shall be conclusive and binding on the holders of Company Common Stock absent manifest error in any such computation.

2.2 Exchange of Certificates.

(a) Parent shall appoint an agent (the “Exchange Agent”) reasonably acceptable to the Company for the purpose of exchanging certificates which immediately prior to the Effective Time evidenced shares of Company Merger Stock (the “Company Certificates”) for the applicable Closing Merger Consideration pursuant to an exchange agent agreement in form and substance reasonably satisfactory to the Company. At the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, Parent Certificates representing the Closing Merger Consideration to be exchanged or paid in accordance with this Article II, and Parent shall make available from time to time after the Effective Time as necessary, cash in an amount sufficient to pay any cash payable in lieu of fractional shares with respect to the Closing Merger Consideration pursuant to Section 2.2(i) and any dividends or distributions to which holders of shares of Company Merger Stock may be entitled pursuant to Section 2.2(c). Parent shall send, or shall cause the Exchange Agent to send, to each holder of record of shares of Company Merger Stock, promptly after the Effective Time, (i) a letter of transmittal for use in such exchange (which shall be in form and substance reasonably satisfactory to Parent and the Company and shall specify that the delivery shall be effected, and risk of loss and title in respect of the Company Certificates shall pass, only upon proper delivery of the

A-3

Company Certificates to the Exchange Agent) and (ii) instructions to effect the surrender of the Company Certificates in exchange for the applicable Closing Merger Consideration, cash payable in respect thereof in lieu of any fractional shares pursuant to Section 2.2(i) and any dividends or other distributions payable in respect thereof pursuant to Section 2.2(c).

(b) Each holder of shares of Company Merger Stock that have been converted into a right to receive the Merger Consideration and any dividends or other distributions payable in respect thereof pursuant to Section 2.2(c), upon surrender to the Exchange Agent of a Company Certificate or Company Certificates, together with a properly completed letter of transmittal covering such shares and such other documents as the Exchange Agent may reasonably require, shall be entitled to receive the applicable Merger Consideration payable in respect of such shares of Company Merger Stock. The holder of such Company Certificate, upon its delivery thereof to the Exchange Agent, shall also receive any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c) and cash payable in respect thereof in lieu of any fractional shares pursuant to Section 2.2(i). Company Certificates surrendered shall forthwith be canceled as of the Effective Time. Until so surrendered, each such Company Certificate, following the Effective Time, shall represent for all purposes only the right to receive the applicable Merger Consideration, cash payable in respect thereof in lieu of any fractional shares pursuant to Section 2.2(i) and any dividends or other distributions payable in respect thereof pursuant to Section 2.2(c). No interest shall be paid or accrued for the benefit of holders of the Company Certificates on cash amounts payable upon the surrender of such Company Certificates pursuant to this Section 2.2.

(c) Whenever a dividend or other distribution is declared or made after the date hereof with respect to Parent Class A Common Stock or Parent Common Stock with a record date after the Effective Time, such declaration shall include a dividend or other distribution in respect of all shares of Parent Class A Common Stock or Parent Common Stock, as applicable, issuable pursuant to this Agreement, including the Escrow Shares. No dividends or other distributions declared or made after the Effective Time with respect to Parent Class A Common Stock or Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Certificate with respect to the Parent Class A Common Stock and Parent Common Stock such holder is entitled to receive until the holder of such Company Certificate shall surrender such Company Certificate in accordance with the provisions of this Section 2.2. Subject to applicable Law, following surrender of any such Company Certificate, there shall be paid to the record holder of the certificates representing Parent Class A Common Stock or Parent Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such Parent Class A Common Stock or Parent Common Stock.

(d) In the event that a transfer of ownership of shares of Company Merger Stock is not registered in the stock transfer books or ledger of the Company, or if any certificate for the applicable Merger Consideration is to be issued in a name other than that in which the Company Certificate surrendered in exchange therefor is registered, it shall be a condition to the issuance thereof that the Company Certificate or Company Certificates so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such exchange shall have paid to the Exchange Agent any transfer or other Taxes required as a result of the issuance of a certificate for Parent Class A Common Stock or Parent Common Stock in any name other than that of the registered holder of such shares of Company Merger Stock, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. If, after the Effective Time, any Company Certificate formerly representing shares of Company Common Stock is presented to the Surviving Entity, it shall be canceled and exchanged for the applicable Merger Consideration provided for, and in accordance with the procedures set forth, in this Article II.

(f) None of Parent, MergerCo, the Company or any of their respective Subsidiaries or Affiliates shall be liable to any holder of shares of Company Merger Stock for any Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

A-4

(g) Each of the Exchange Agent, the Surviving Entity, Parent and the Escrow Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable to any holder of shares of Company Merger Stock, and from any cash dividends or other distributions that the holder is entitled to receive under Section 2.2(c), such amounts as the Exchange Agent, the Surviving Entity, Parent or the Escrow Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of U.S. federal, state or local tax Law or any other non-U.S. tax Law or any other applicable requirement of Law. The Surviving Entity and Parent hereby agree to, and to use commercially reasonable efforts to cause the Exchange Agent and the Escrow Agent to, remit any such amounts to the appropriate Governmental Authority. To the extent that amounts are so withheld by the Exchange Agent, the Surviving Entity, Parent or the Escrow Agent and remitted to the applicable Governmental Authority, such amounts withheld from the Merger Consideration and such other amounts payable under Section 2.2(c) shall be treated for all purposes of this Agreement as having been received by the holder of the shares of Company Merger Stock in respect of which such deduction and withholding was made by the Exchange Agent, the Surviving Entity, Parent or the Escrow Agent.

(h) Any portion of the certificates evidencing the Parent Class A Common Stock, Parent Common Stock, the cash to be paid in respect of fractional shares pursuant to Section 2.2(i), and the cash or other property in respect of dividends or other distributions pursuant to Section 2.2(c) supplied to the Exchange Agent which remains unclaimed by the holders of shares of Company Merger Stock for a period of time longer than twelve months after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged his shares of Company Merger Stock for the applicable Merger Consideration in accordance with this Section 2.2 prior to the time of demand shall thereafter look only to Parent for delivery of the applicable Merger Consideration, and payment of any cash payable in respect thereof in lieu of any fractional shares pursuant to Section 2.2(i) and any dividends or distributions with respect to Parent Class A Common Stock and Parent Common Stock to which they were entitled pursuant to Section 2.2(c), in each case, without interest.

(i) No certificates representing a fractional share of Parent Class A Common Stock or Parent Common Stock shall be issued in exchange for shares of Company Merger Stock upon the surrender for exchange of a Company Certificate. In lieu of any such fractional share, each holder of shares of Company Merger Stock who would otherwise have been entitled to a fraction of a share of Parent Class A Common Stock or Parent Common Stock upon surrender of Company Certificates for exchange (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit in the manner provided in Section 2.2(j)) shall be paid upon such surrender (and after taking into account and aggregating shares of Parent Class A Common Stock represented by all Company Certificates surrendered by such holder and separately taking into account and aggregating shares of Parent Common Stock represented by all Company Certificates surrendered by such holder) cash (without interest) in an amount equal to the product obtained by multiplying (a) the fractional share interest of Parent Class A Common Stock or Parent Common Stock, as applicable, to which such holder (after taking into account and aggregating all shares of Parent Class A Common Stock or Parent Common Stock, as applicable, represented by all Company Certificates surrendered by such holder) would otherwise be entitled by (b) the Closing Market Price (it being understood that such Closing Market Price shall also be used with respect to any fractional share of Parent Class A Common Stock). In addition, in lieu of the release of any fractional Escrow Share pursuant to the Escrow Agreement, each holder of shares of Company Merger Stock who would otherwise have been entitled to a fraction of an Escrow Share (and after taking into account and aggregating any fractional Escrow Shares to which such holder would otherwise be entitled) shall be paid at such time as the fractional Escrow Share would otherwise have been released to such holder pursuant to the Escrow Agreement a cash payment (without interest) from Parent in an amount equal to the product obtained by multiplying (a) the fractional share interest of an Escrow Share (and after taking into account and aggregating any fractional Escrow Shares to which such holder would otherwise be entitled) to which such holder would otherwise be entitled by (b) the Closing Market Price. Upon payment by Parent for any fractional Escrow Share, such fractional Escrow Share shall be canceled and retired and shall cease to exist.

A-5

(j) In the event any Company Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Company Certificates, upon the making of an affidavit of that fact by the holder thereof, the applicable Merger Consideration and any dividends or other distributions as may be required pursuant to this Article II in respect of the shares of Company Merger Stock represented by such lost, stolen or destroyed Company Certificates.

2.3 Escrow. Immediately prior to the Effective Time, the Shareholders’ Representative and Parent shall enter into an escrow agreement substantially in the form of Exhibit D attached hereto (the “Escrow Agreement”) with an escrow agent (the “Escrow Agent”) reasonably acceptable to the Company and Parent. At the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Escrow Agent, Parent Certificates or a book-entry in Escrow Agent’s account representing the Escrow Shares. The Escrow Shares shall be held and distributed pursuant to the Escrow Agreement.

2.4 Dissenters’ Rights.

(a) Notwithstanding anything in this Agreement to the contrary, any shares of Company Common Stock (“Dissenting Shares”) which are issued and outstanding immediately prior to the Effective Time and which are held by stockholders of the Company who have filed with the Company, before the taking of the vote of the stockholders of the Company to adopt and approve this Agreement, written objections to such approval stating their intention to demand payment for such shares of Company Common Stock if the Merger is consummated, and who have not voted such shares of Company Common Stock in favor of the adoption and approval of this Agreement and have otherwise complied in all respects with the applicable provisions of Sections 92A.300 through 92A.500 of the NRS (the “Dissenters’ Rights Provisions”), will not be converted as described in Section 2.1, but will thereafter constitute only the right to receive payment of the fair value of such shares of Company Common Stock in accordance with the Dissenters’ Rights Provisions; provided, however, that all shares of Company Common Stock held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such shares of Company Common Stock under the Dissenters’ Rights Provisions shall thereupon be deemed to have been canceled and retired and to have been converted, as of the Effective Time, into the right to receive the Merger Consideration, without interest, in the manner provided in Section 2.2. Persons who have perfected statutory rights with respect to Dissenting Shares as aforesaid will not be paid the Merger Consideration by the Surviving Entity as provided in this Agreement and will have only such rights as are provided by the Dissenters’ Rights Provisions with respect to such Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, if Parent, MergerCo or the Company abandon or are finally enjoined or prevented from carrying out, or the stockholders rescind their adoption and approval of, this Agreement, the right of each holder of Dissenting Shares to receive the fair value of such Dissenting Shares in accordance with the Dissenters’ Rights Provisions will terminate, effective as of the time of such abandonment, injunction, prevention or rescission. The Company shall give Parent and MergerCo prompt notice of any demands received by the Company for the exercise of dissenters’ rights with respect to shares of Company Common Stock and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent (which shall not be unreasonably withheld), make any payment with respect to, or settle or offer to settle, any such demands.

(b) Each dissenting stockholder who becomes entitled under the Dissenters’ Rights Provisions to payment for Dissenting Shares shall receive payment therefor after the Effective Time from the Surviving Entity (but only after the amount thereof shall have been agreed upon or finally determined pursuant to the Dissenters’ Rights Provisions), and such shares of Company Common Stock shall be canceled.

A-14

Knowledge of the Company, nothing has occurred that would materially and adversely affect the qualification of any such plan.

No litigation has been commenced with respect to any Company Benefit Plan and, to the Knowledge of the Company, no such litigation is threatened (other than routine claims for benefits). There are no governmental audits or investigations pending or, to the Knowledge of the Company, threatened in connection with any Company Benefit Plan.

No payment or benefit which has been, will or may be made by the Company or any Subsidiary of the Company with respect to any current or former employee in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement is reasonably likely to result in a material amount of “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code.

(d) If, upon termination of the Escrow Agreement, neither SpinCo nor the Company has obtained the Closure Letter and/or neither SpinCo nor the Company has obtained an NFR in connection with a New Belvidere Issue (if any), SpinCo shall reserve an amount equal to 110% of the amount deemed sufficient, in the reasonable opinion of a third party environmental consultant engaged by Parent, after consultation with SpinCo, to fund such actions as are necessary to obtain the Closure Letter and the NFR, as applicable. In addition, if, immediately prior to the end of the Survival Period for SpinCo’s indemnification obligations under Article VII of this Agreement, neither SpinCo nor the Company has sold the Belvidere Property to a third party reasonably acceptable to Parent, SpinCo shall provide such further assurances to Parent as Parent’s general counsel shall reasonably request, after consultation and cooperation with SpinCo, to address (i) any identified risks of Releases of any Hazardous Substance on, in, under, or migrating from the Belvidere Property, which Hazardous Substance was present on, in or under the Belvidere Property at or prior to the Effective Time, and (ii) any other matters on, in, under, or migrating from the Belvidere Property that would reasonably be expected to result in liability to Parent or the Surviving Entity under Environmental Laws.

(a) For a period of not less than six years from and after the Effective Time, the Certificate of Formation and Operating Agreement of the Surviving Entity shall contain provisions no less favorable to the directors and officers of the Company with respect to exculpation of directors and officers of the Company for periods at or prior to the Effective Time than are currently set forth in the Organizational Documents of the Company.

(c) In the event Parent or the Surviving Entity (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, shall assume the obligations set forth in this Section 5.13.

5.15 Notice of Breach. Each party hereto shall notify each other party promptly if such party has Knowledge of any breach or violation of any of such party’s own representations, warranties, covenants or agreements hereunder. No disclosure by any party pursuant to this Section 5.15, however, shall be deemed to amend or supplement the schedule referred to in such representation or warranty or to prevent or cure any misrepresentations, breach of warranty or breach of covenant.

5.16 Transaction-Related Claims. From and after the date hereof, each party hereto shall notify each other party promptly if it has Knowledge of any Transaction-Related Claim, which notice shall describe the Transaction-Related Claim in reasonable detail.

Parent shall control the defense of any Transaction-Related Claim to the extent involving Parent or MergerCo or any of their respective Affiliates, directors, officers or employees (each, a “Parent Party”), provided, that (a) a Parent Party’s selection of legal counsel for the defense of any such Transaction-Related Claim shall be subject to the approval of the Company (and, after the Effective Time, the approval of SpinCo and the Shareholders’ Representative) (such approval not to be unreasonably withheld or delayed) and (b) the Company (and, after the Effective Time, SpinCo and the Shareholders’ Representative) shall have the right at its expense to participate in the defense assisted by counsel of its own choosing. A Parent Party shall have the right to compromise and settle a Transaction-Related Claim only with the prior written consent of the Company (and, after the Effective Time, the consent of SpinCo and the Shareholders’ Representative), which consent shall not be unreasonably withheld or delayed.

If the Parent Party does not consent to such offer within 10 days after its receipt of such notice, the Parent Party may continue to contest or defend such Transaction-Related Claim and, in such event, the maximum liability of the Company, SpinCo or any other Indemnifying Person as to such Transaction-Related Claim (pursuant to the indemnification provisions of Article VII or otherwise) will not exceed the amount of such settlement offer, plus costs and expenses paid or incurred by the Parent Party through the date such settlement offer is given to the Parent Party. Notwithstanding anything to the contrary in Section 7.4, the procedures in this Section 5.16 shall apply to any Transaction-Related Claim. The provisions in Section 7.5 shall apply with respect to any Transaction-Related Claim.

5.17 Cancellation of Company Parent Stock Holdings.

If SpinCo deposits $4 million in escrow pursuant to clause (ii) prior to the release of all of the Escrow Shares pursuant to the Escrow Agreement, Parent shall cause to be released to the Shareholders’ Representative for distribution to the Former Company Shareholders in accordance with the Escrow Agreement the number of Escrow Shares equal to the lesser of (x) Escrow Shares with an aggregate value of $4 million (based on the Average Closing Market Price) and (y) all of the Escrow Shares then remaining with the Escrow Agent subject to the Escrow Agreement.

5.19 Resignation of Officers and Directors. The officers and directors of the Company shall resign as of or prior to the Effective Time and the Company shall provide evidence of such resignations to Parent.

(g) the exercise by any stockholder of the Company of dissenters’ rights pursuant to Section 2.4 (it being agreed that the determination of any Damages resulting therefrom shall take into account, to the extent applicable, the benefit to Parent of not having to pay any such stockholder any Merger Consideration that such stockholder otherwise would have been entitled to receive in the Merger, with the value of the Merger Consideration being based on the Average Closing Market Price);

A-31

(h) any rights to indemnification, reimbursement or compensation from the Company asserted by any individual who served as a director or officer of the Company prior to the Effective Time, whether pursuant to any of the Company’s Organizational Documents, Contracts or otherwise and whether or not related to claims pending on, or asserted after, the Closing Date;

7.3 Survival; Right to Indemnification Not Affected by Knowledge. The representations, warranties, covenants and agreements of the Company, Parent and MergerCo in this Agreement or in any Ancillary Agreement (other than, with respect to Parent and MergerCo, the Non-Surviving Representations and Warranties) shall survive the Closing (a) for a period of five years after the Closing Date with respect to indemnification claims against SpinCo under Section 7.1 or indemnification claims against Parent under Section 7.2 and (b) for a period of two years after the Closing Date with respect to indemnification claims under Section 7.1 from the Escrow Shares (either such period, as applicable, a “Survival Period”) and shall thereafter terminate and be of no further force or effect; provided, however, that the right to receive payment of Tax benefits described in Section 7.5(c) or 7.6(c) shall survive indefinitely.

A-32

7.4 Indemnification Procedures. All claims or demands for indemnification under Sections 7.1 and 7.2 shall be asserted and resolved as follows:

(a) As soon as is reasonably practicable after any Parent Indemnified Party or Company Indemnified Party becomes aware of any claim, event or circumstance (a “Claim”) that has or might give rise to an indemnification obligation under Section 7.1 or Section 7.2 of this Agreement, such Parent Indemnified Party or Company Indemnified Party, as the case may be (an “Indemnified Person”), shall give written notice thereof (a “Claim Notice”) to the party or parties from which indemnification is sought (the “Indemnifying Persons”). The Claim Notice shall describe the Claim in reasonable detail and shall indicate the amount (estimated if necessary and to the extent feasible) of the Damages that have been or may be suffered by the Indemnified Person. The failure of any Indemnified Person to promptly give the Indemnifying Persons a Claim Notice shall not preclude such Indemnified Person from obtaining indemnification under this Article VII, except to the extent, and only to the extent, that such Indemnified Person’s failure has actually prejudiced the rights or increased the Damages and obligations of any of the Indemnifying Persons hereunder.

(b) With respect to any Claim Notice relating to a Claim made by a third party against an Indemnified Person (a “Third Party Claim”), the Indemnifying Person shall have the right upon written notice (a “Control Notice”) to the Indemnified Person within 30 days after receipt from the Indemnified Person of the Claim Notice, to conduct at its expense with counsel reasonably satisfactory to the Indemnified Person the defense against such Third Party Claim in its own name or, if necessary, in the name of the Indemnified Person; provided, however, that (i) the Indemnifying Person may only assume control of such defense if the Indemnifying Person acknowledges in writing to the Indemnified Person that any Damages that may be assessed against the Indemnified Person in connection with such suit or proceeding constitute Damages for which the Indemnified Person shall be indemnified pursuant to this Article VII, and (ii) the Indemnifying Person may not assume control of the defense of a suit or proceeding (A) involving criminal liability or (B) in which any relief other than monetary damages is sought against the Indemnified Person. Except for the matters set forth in Subsections (A) and (B) of the prior sentence for which the consent of the Indemnifying Person is not required, the Indemnified Person shall not settle a Third Party Claim without the prior written consent of the Indemnifying Person (such consent not to be unreasonably withheld or delayed). In the event that the Indemnifying Person delivers a Control Notice, the Indemnified Person will cooperate with and make available to the Indemnifying Person such assistance and materials as may be reasonably requested by it, and the Indemnified Person shall have the right at its expense to participate in the defense assisted by counsel of its own choosing. Without the prior written consent of the Indemnified Person (such consent not to be unreasonably withheld or delayed), the Indemnifying Person will not enter into any settlement of any Third Party Claim or cease to defend against such Third Party Claim; provided, that the Indemnified Person may withhold its consent in its sole discretion if pursuant to or as a result of such settlement or cessation, (i) injunctive or other equitable relief would be imposed against the Indemnified Person or (ii) such settlement or cessation would lead to material liability or create any material financial or other obligation on the part of the Indemnified Person for which the Indemnified Person is not entitled to indemnification hereunder. The Indemnified Persons may employ one separate counsel (and one local counsel in each applicable jurisdiction) and the reasonable out-of-pocket fees and expenses of such counsel shall be paid by the Indemnifying Persons if the named parties to the Third Party Claim (including any impleaded parties) include the Indemnified Person or Indemnified Persons, as applicable, and the Indemnified Person or Indemnified Persons, as applicable, reasonably determines that the Indemnified Person or Indemnified Persons, as applicable, and the Indemnifying Person have conflicting interests or different defenses available with respect to such Third Party Claim, provided, that the Indemnifying Persons shall not be required to pay the fees and expenses of more than one counsel for all Indemnified Persons (and one local counsel in each applicable jurisdiction) in connection with any one Third Party Claim or related group of Third Party Claims. If an offer is made to settle a Third Party Claim, which offer the Indemnifying Person is permitted to settle under this Section 7.4(b) only upon the prior written consent of the Indemnified Person, and the Indemnifying Person desires to accept and agree to such offer, the Indemnifying Person will give prompt written notice to the Indemnified Person to that effect. If the Indemnified Person does not

A-33

consent to such firm offer within twenty calendar days after its receipt of such notice, the Indemnified Person may continue to contest or defend such Third Party Claim and, in such event, the maximum liability of the Indemnifying Person as to such Third Party Claim will not exceed the amount of such settlement offer, plus costs and expenses paid or incurred by the Indemnified Person through the date such settlement offer is given to the Indemnified Person to the extent such amount is otherwise indemnifiable hereunder.

(c) Notwithstanding the provisions of Section 9.6, each Indemnifying Person hereby consents to the nonexclusive jurisdiction of any court in which a claim or cause of action in respect of a Third Party Claim is brought against any Indemnified Person for purposes of any such claim that such Indemnified Person may have against the Indemnifying Person under this Agreement with respect to such Third Party Claim.

(d) In accordance with Section 7.8, the Shareholders’ Representative shall act as nominee for the Former Company Shareholders with respect to any claim for indemnification under Section 7.1 against the Escrow Shares, and any reference in this Section 7.4 to an Indemnifying Person with respect to the indemnification procedures for a Claim against the Escrow Shares shall mean the Shareholders’ Representative in such capacity pursuant to Section 7.8.

7.5 Limits on Indemnification; Calculation of Damages.

(a) The sole and exclusive source of satisfaction and payment for any indemnification claims made by any Parent Indemnified Parties against the Former Company Shareholders pursuant to Section 7.1 shall be a claim against the Escrow Shares pursuant to the Escrow Agreement, and the Former Company Shareholders and the Shareholders’ Representative, individually or as a group, shall not have any obligation, responsibility or personal liability for the satisfaction and payment of any indemnification obligations hereunder. This limitation on indemnification by the Former Company Shareholders shall not serve as a limit on the indemnification obligations of SpinCo under this Agreement. The indemnification obligations pursuant to Section 7.1(i) shall be satisfied within ten Business Days after a final determination (within the meaning of Section 1313(a) of the Code) of the relevant Tax is made. In pursuing the collection of Damages pursuant to Section 7.1, the Parent Indemnified Parties shall proceed first against SpinCo (including any escrow established by SpinCo pursuant to Section 5.18) prior to pursuing any claim against the Escrow Shares pursuant to the Escrow Agreement; provided, however, that if SpinCo has not satisfied all Damages for which payment is due with respect to a Claim within 15 days after the earlier of (i) an agreement among SpinCo, the Shareholders’ Representative and the applicable Parent Indemnified Parties as to such Damages that are due with respect to a Claim or (ii) a final judgment with no further right to appeal has established the right of the applicable Parent Indemnified Parties to such Damages, then the Parent Indemnified Parties may proceed against the Escrow Shares pursuant to the Escrow Agreement to collect such Damages.

(b) The amount of any indemnifiable Damages under this Article VII shall be calculated after giving effect to any amount received by the applicable Indemnified Person with respect to the applicable Claim under any insurance coverage or any indemnity, contribution or other similar payment received by the Indemnified Person from any third party with respect thereto, but net of any expenses incurred by such Indemnified Person in collecting such amount. The Indemnified Persons shall use their respective commercially reasonable efforts to collect any amounts available under any such insurance coverage or right to indemnification, contribution or other similar payment. If any Indemnified Person receives an amount with respect to any Claim under insurance coverage or right to indemnification, contribution or other similar payment at any time subsequent to its receipt of any indemnification recovery hereunder with respect to the same Damages, then such Indemnified Person shall promptly pay to the Indemnifying Person the amount by which the insurance, indemnification, contribution or other payments plus the amount of any indemnification payments for the same Damages made hereunder exceeds the total amount of Damages suffered or incurred by the Indemnified Person with respect to the same facts or circumstances giving rise to the right to indemnification under this Article VII.

(c) The amount of any indemnifiable Damages under this Article VII shall be calculated after giving effect to any Tax benefit (through an actual reduction of Taxes or refund of Taxes paid) resulting from the

A-34

applicable Claim, provided, that no indemnifiable Damages shall be reduced prior to the taxable period in which the Indemnified Person realizes such Tax benefit and, if such Tax benefit will be realized in periods after the indemnification payment is due, the Indemnifying Person shall be required to pay the full indemnification amount subject to the Indemnified Person’s obligation to pay the amount of such Tax benefit when realized to the Indemnifying Person (or, with respect to any Claim satisfied from the Escrow Shares, to the Shareholders’ Representative for the account of the Former Company Shareholders). The Indemnified Persons shall use their reasonable best efforts to maximize the amount of any Tax benefits in connection with the applicable Claim.

(d) Notwithstanding anything to the contrary herein, the Parent Indemnified Parties shall not have any right to indemnification for Damages pursuant to Section 7.1 to the extent that any such Damages result from or arise out of, directly or indirectly, (i) any financial information supplied by Parent or MergerCo for inclusion in the Form S-4 or the Joint Proxy Statement/Prospectus or (ii) any information of Parent or MergerCo incorporated by reference in the Form S-4 or the Joint Proxy Statement/Prospectus.

(e) SpinCo hereby waives any right to (i) seek contribution or other payment from the Company with respect to any Damages for which SpinCo is required to indemnify the Parent Indemnified Parties pursuant to this Article VII or (ii) bring a claim against the current or former directors of the Company as result of Damages for which SpinCo is required to indemnify the Parent Indemnified Parties pursuant to this Article VII.

7.6 Certain Tax Procedures.

(a) Parent shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Surviving Entity that are filed after the Closing Date which relate to a Pre-Closing Tax Period. Parent shall permit the Shareholders’ Representative to review any such Tax Return described in the preceding sentence which relates to a Pre-Closing Tax Period prior to filing and shall make such revisions to such Tax Returns as are reasonably requested by the Shareholders’ Representative.

(b) Any Tax refunds of the Surviving Entity that are received by Parent or any of its Subsidiaries, including the Surviving Entity that relate to any Pre-Closing Tax Period shall be for the account of the Former Company Shareholders, and Parent shall pay over to the Shareholders’ Representative any such refund within 15 days after receipt or entitlement thereto.

(c) Parent shall pay to the Shareholders’ Representative for the account of the Former Company Shareholders the amount of any Tax benefits actually realized by Parent or any of its Subsidiaries, including the Surviving Entity, from Tax Benefit Items when realized by Parent or any of its Subsidiaries, including the Surviving Entity. For the purposes of this Section 7.6(c), the amount of the Tax benefit attributable to Tax Benefit Items will be based upon the difference between net income Taxes actually paid and the net income Taxes which would have been paid without the benefit of the Tax Benefit Items. Parent shall provide the Shareholders’ Representative with copies of all calculations of actual Tax benefits attributable to Tax Benefit Items reasonably requested by the Shareholders’ Representative.

(d) Parent and the Shareholders’ Representative shall cooperate, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Section 7.6 and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Neither Parent nor any Subsidiary of Parent shall agree to settle or concede any audit, litigation or other proceeding with a taxing authority with respect to any Pre-Closing Tax Period without the prior written consent of the Shareholders’ Representative.

(e) A Tax benefit described in Section 7.5(c) or Section 7.6(c) shall be treated as realized only to the extent that Parent or its Subsidiaries have not, by the due date (including extensions) of the Tax Return for

A-35

the last period from which losses or credits can be carried back, generated a loss or credit to offset the income or Tax giving rise to such potential Tax benefit.

7.7 Exclusive Remedy.

The relative rights, preferences and limitations of each class shall be as follows:

(A)

Class A Common Stock and Common Stock

Except as provided in this Article 4, the Class A Common Stock and the Common Stock shall have the same rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

B-3

(1)

Dividends; Combinations; and Subdivisions.

(a)

The holders of the Class A Common Stock and Common Stock shall be entitled to receive, when and as declared by the board of directors, such dividends including share distributions (as defined in paragraph (A)(1)(b)) as may be declared from time to time by the board of directors subject to any limitations applicable by law of the State of Delaware, to the rights of the holders of the Preferred Stock, and to the following limitation. Whenever a dividend which is not a share distribution is paid to the holders of Class A Common Stock, the corporation shall also pay to the holders of Common Stock a dividend per share at least equal to the dividend per share paid to the holders of the Class A Common Stock. The corporation may pay dividends which are not share distributions to holders of Common Stock in excess of dividends paid, or without paying dividends, to holders of Class A Common Stock.

(b)

If at any time a distribution is to be paid in Class A Common Stock or Common Stock (a “share distribution”), such share distribution may be declared and distributed only as follows:

(i)

Shares of one class of either the Class A Common Stock or the Common Stock (the “first class”) may be distributed on shares of that class, provided that there is declared and paid a simultaneous distribution of shares of the other class of stock (the “second class”) to the holders of the second class which simultaneous distribution shall consist of a number of shares of the second class equal on a per share basis to the number of shares of the first class which are distributed to holders of the first class.

(ii)

Subject to any limitations of the laws of the State of Delaware, shares of the first class may be distributed on shares of the second class, provided that there is declared and paid a simultaneous distribution of shares of the first class to holders of shares of the first class which simultaneous distribution shall consist of a number of shares of the first class equal on a per share basis to the number of shares of the first class which are distributed to holders of the second class.

(c)

The corporation shall not combine or subdivide shares of the first class without making a simultaneous combination or subdivision of shares of the second class which is equal on a per share basis to the combination or subdivision of the shares of the first class.

(2)

Voting.

Voting power shall be divided between the Class A Common Stock and the Common Stock as follows:

(a)

With respect to the election of directors, holders of the Common Stock, voting as a separate class, shall be entitled to elect that number of directors which constitutes 33¹/3% of the authorized number of members of the board of directors and, if such 33¹/3% is not a whole number, then the holders of the Common Stock shall be entitled to elect to the nearest higher whole number of directors that is at least 33¹/3% of such membership. Holders of Class A Common Stock, voting as a separate class but subject to any voting rights which may be granted to holders of Preferred Stock, shall be entitled to elect the remaining directors.

(b)

The holders of Class A Common Stock shall be entitled to vote as a separate class but subject to any voting rights which may be granted to holders of Preferred Stock, on the removal with or without cause, of any director elected by the holders of Class A Common Stock, and the holders of Common Stock shall be entitled to vote as a separate class on the removal, with or without cause, of any director elected by the holders of Common Stock.

(c)

In the discretion of the board of directors, (i) any vacancy in the office of a director elected by the holders of the Class A Common Stock may be filled by a vote of such holders, voting as a separate class but subject to any voting rights which may be granted to holders of Preferred Stock, and any vacancy in the office of a director elected by the holders of the Common Stock may be filled by a vote of such holders, voting as a separate class, or (ii) in the case of a vacancy in the

B-4

office of a director elected by either class, such vacancy may be filled by the remaining directors. Any director elected by the board of directors to fill a vacancy shall serve until the next Annual Meeting of Stockholders and until his successor has been elected and has qualified. If permitted by the By-Laws, the board of directors may (i) increase the number of directors and any vacancy so created may be filled by the board of directors, or (ii) decrease the number of directors; provided that, so long as the holders of Common Stock had the rights provided in paragraph (A)(2)(a) of this Article 4 in respect of the last Annual Meeting of Stockholders, the board of directors may be so enlarged (or so decreased) only to the extent that at least 33¹/3% of the enlarged (or decreased) board consists of directors elected by the holders of the Common Stock or by directors appointed to fill vacancies created by the death, resignation or removal of directors elected by the holders of the Common Stock.

(d)

The Common Stock will not have the right to elect directors set forth in paragraphs (A)(2)(a) and (A)(2)(c) of this Article 4, if, on the record date of any stockholder meeting at which directors are to be elected, the number of issued and outstanding shares of Common Stock is less than 10% of the aggregate number of issued and outstanding shares of Class A Common Stock and Common Stock. In such case, all directors to be elected at such meeting shall be elected by holders of Class A Common Stock and Common Stock, voting together as a single class but subject to any voting rights which may be granted to holders of Preferred Stock, provided that with respect to said election, the holders of Class A Common Stock shall have one vote per share and holders of Common Stock shall have one-tenth vote per share. The Class A Common Stock will not have the right to elect directors set forth in paragraphs (A)(2)(a) and (A)(2)(c) of this Article 4, if, on the record date for any stockholder meeting at which directors are to be elected, the number of issued and outstanding shares of Class A Common Stock is less than 12.5% of the aggregate number of issued and outstanding shares of Class A Common Stock and Common Stock. In such case, holders of Common Stock, voting as a separate class, shall have the right to elect 33¹/3% of the members of the board of directors as provided in paragraph (A)(2)(a) of this Article 4, and holders of Class A Common Stock and Common Stock voting together as a separate class but subject to any voting rights which may be granted to holders of Preferred Stock, shall be entitled to elect the remaining directors, provided that with respect to said election, the holders of Class A Common Stock shall have one vote per share and the holders of Common Stock shall have one-tenth vote per share.

(e)

Subject to the provisions of section (D) of this Article 4, the holders of Class A Common Stock and Common Stock shall in all matters not specified in paragraphs (A)(2)(a), (b), (c) and (d) of this Article 4 vote together as a single class but subject to any voting rights which may be granted to holders of Preferred Stock, provided that the holders of Class A Common Stock shall have one vote per share and the holders of Common Stock shall have one-tenth vote per share.

(f)

Notwithstanding anything in this subsection (A)(2) or in section (D) of this Article 4 to the contrary but subject to any voting rights which may be granted to holders of Preferred Stock, the holders of Class A Common Stock shall have exclusive voting power on all matters, at any time when no Common Stock is issued and outstanding, and the holders of Common Stock shall have exclusive voting power on all matters at any time when no Class A Common Stock is issued and outstanding.

(3)

Conversion.

(a)

The holder of any shares of Class A Common Stock at his option will be entitled at any time to convert each share of Class A Common Stock into one share of Common Stock. Such right shall be exercised by the surrender of the shares of Class A Common Stock so to be converted to the corporation at any time during normal business hours at the office or agency then maintained by it for payment of dividends on the shares of the Class A Common Stock and the Common Stock (the “Payment Office”), accompanied by written notice of such holder’s election to convert and (if so

B-5

required by the corporation or any conversion agent) by instruments of transfer, in form satisfactory to the corporation and to any conversion agent, duly executed by the registered holder or by his duly authorized attorney.

(b)

As promptly as practicable after the surrender for conversion of any shares of Class A Common Stock in the manner provided in paragraph A(3)(a) of this Article 4, the corporation will deliver or cause to be delivered at the Payment Office to or upon the written order of the holder of such shares, certificates representing the number of full shares of Common Stock issuable upon such conversion, issued in such name or names as such holder may direct. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Class A Common Stock, and all rights of the holder of such shares as a holder of such shares shall cease at such time and the person or persons in whose name or names the certificates for shares of Common Stock are to be issued shall be treated for all purposes as having become the record holder or holders thereof at such time; provided, however, that any such surrender on any date when the stock transfer books of the corporation shall be closed shall constitute the person or persons in whose name or names the certificates for such shares of Common Stock are to be issued as the record holder or holders thereof for all purposes immediately prior to the close of business on the next succeeding day on which such stock transfer books are opened.

(c)

No adjustments in respect of dividends shall be made upon the conversion of any shares of the Class A Common Stock; provided, however, that if shares of Class A Common Stock shall be converted subsequent to the record date preceding a dividend payment on the Class A Common Stock but prior to the payment date for such dividend, the registered holder of such shares of Class A Common Stock at the close of business on such record date nonetheless shall be entitled to receive the dividend paid on such shares, if any, on such payment date notwithstanding the conversion thereof.

(d)

The corporation covenants that it will at all times reserve and keep available, solely for the purpose of issue upon conversion of the shares of Class A Common Stock, such number of shares of Common Stock as shall be issuable upon the conversion of all such outstanding shares of Class A Common Stock, provided, that nothing contained herein shall be construed to preclude the corporation from satisfying its obligations in respect of the conversion of the shares of Class A Common Stock by delivery of shares of Common Stock which are held in the treasury of the corporation.

The corporation covenants that all shares of Common Stock which shall be issued upon conversion of the shares of the Class A Common Stock will upon issue be fully paid and non-assessable and not subject to any preemptive rights, except as otherwise required by applicable law.

(e)

If the number of issued and outstanding shares of Class A Common Stock is less than 2,397,976 (subject to adjustment for any combination or consolidation of the Class A Common Stock, by reclassification or otherwise, into a greater or lesser number of shares of Class A Common Stock, or any dividend payable in Class A Common Stock), then, in accordance with and subject to paragraph A(3)(g) of this Article 4, each share of Class A Common Stock shall automatically be converted into one share of Common Stock.

B-6

(f)

If, after the Effective Time (as defined in the SICO Merger Agreement), beneficial ownership of shares of Class A Common Stock is transferred by any Existing Class A Holder, whether by sale, assignment, gift, bequest, appointment or otherwise, to any person other than a Permitted Transferee (a “Non-Permitted Transfer”), then, in accordance with and subject to paragraph A(3)(g) of this Article 4, each share of Class A Common Stock so transferred shall automatically be converted into one share of Common Stock. The following definitions shall apply to this paragraph A(3)(f):

(i)

“Existing Class A Holder” shall mean any beneficial owner of shares of Class A Common Stock as of immediately after the Effective Time, and any Permitted Transferee of such Existing Class A Holder to whom Class A Common Stock has been transferred in accordance with this paragraph A(3)(f);

(ii)

“Permitted Transferee” shall mean, with respect to any Existing Class A Holder, (A) any Related Party of such Existing Class A Holder, (B) any Smith Family Member, and (C) any other person approved as a “Permitted Transferee” by the board of directors of the corporation;

(iii)

“Related Party” shall mean: (A) with respect to any Existing Class A Holder that is a natural person, the parents, grandparents, siblings, spouses, ex-spouses and issue (natural or adoptive), spouses and ex-spouses of issue (natural or adoptive) and any trust for the benefit of, the estate of or the legal representative of, any of such Existing Class A Holder or such persons (provided, that any such trust shall qualify as a Related Party notwithstanding that a remainder interest in such trust is for the benefit of any other person), any partnership the partners of which are such Existing Class A Holder or one or more of such persons, or any limited liability company, corporation or other entity the ownership interests of which are held by such Existing Class A Holder or one or more of such persons, and (B) with respect to any Existing Class A Holder that is a trust, partnership, limited liability company, corporation or other entity, the beneficiaries of such trust and the partners, members, shareholders or other equity owners of such partnership, limited liability company, corporation or other entity, and the Related Parties of such persons;

(iv)

“Smith Family Member” shall mean any lineal descendant of Lloyd R. Smith and such descendant’s parents, grandparents, siblings, spouses, ex-spouses and issue (natural or adoptive), spouses and ex-spouses of issue (natural or adoptive) and any trust for the benefit of, the estate of or the legal representative of, any of such persons (provided, that any such trust shall qualify as a Smith Family Member notwithstanding that a remainder interest in such trust is for the benefit of any other person), or any partnership the partners of which are one or more of such persons, or any limited liability company, corporation or other entity the ownership interests of which are held by one or more of such persons;

(v)

A “person” means any natural person, trust, limited liability company, corporation or other entity; and

(vi)

The “beneficial owner” of, and “beneficial ownership” of, any shares of Class A Common Stock shall be determined in accordance with Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended.

(g)

In the event of any automatic conversion of shares of Class A Common Stock pursuant to paragraphs A(3)(e) or A(3)(f) of this Article 4, certificates formerly representing outstanding shares of Class A Common Stock subject to such automatic conversion will thereafter be deemed to represent a like number of shares of Common Stock. Such automatic conversion shall be deemed to have been made immediately prior to the close of business on the date on which the event resulting in such automatic conversion shall have occurred, and all rights of the holder of such shares of Class A Common Stock shall cease at such time and such holders shall be treated

B-7

for all purposes as having become the holder or holders of the shares of Common Stock issuable upon such automatic conversion. If an Existing Class A Holder inadvertently transfers shares of Class A Common Stock in a Non-Permitted Transfer, or transfers shares of Class A Common Stock with the bona fide belief that such transfer was not a Non-Permitted Transfer, such Existing Class A Holder shall have the right to cure such Non-Permitted Transfer within 30 calendar days of such person’s receipt of notice from the corporation of its determination that a Non-Permitted Transfer has occurred and, if such Non-Permitted Transfer is cured within such 30 day period, the shares of Class A Common Stock shall be deemed not to have been automatically converted into Common Stock. The corporation may, as a condition to the transfer or the registration of transfer of shares of Class A Common Stock to a purported Permitted Transferee, require the furnishing of such affidavits or other proof as it deems necessary to establish that such transferee is a Permitted Transferee. A good faith determination by the board of directors that a Class A Holder is not a Permitted Transferee, or that no right of cure is available or that such right of cure has lapsed, and that, therefore, an automatic conversion shall have occurred, shall be conclusive and binding on a Class A Holder. The corporation shall note on the certificates representing the shares of Class A Common Stock that transfer by a Class A Holder to a person other than a Permitted Transferee may result in the automatic conversion of such shares of Class A Common Stock pursuant to paragraphs A(3)(e) or A(3)(f) of this Article 4.

(B)

Preferred Stock

(1)

Series of Preferred Stock

The board of directors shall have authority, by resolution or resolutions, to divide the Preferred Stock into series, to establish and designate each such series and the number of shares thereof (which number, by like action of the board of directors from time to time thereafter, may be increased except when otherwise provided by the board of directors in creating such series, or may be decreased but not below the number of shares thereof then outstanding), and to determine and fix the rights, preferences and limitations in respect of the shares of each series established prior to the issuance thereof, and the relative variations therein as between series, to the fullest extent now or hereafter permitted by applicable law of the State of Delaware, and (without limiting the generality of the foregoing) particularly with respect to:

(a)

The rate of dividend and the initial original issue date or other date from which such dividends shall be cumulative;

(b)

The price or prices, at the period or periods within, and the terms and conditions on which shares may or shall be redeemed;

(c)

The amounts payable upon shares in the event of voluntary liquidation or involuntary liquidation;

(d)

The terms of the sinking fund provisions or redemption or purchase account, if any, for the redemption or purchase of shares;

(e)

The terms and conditions on which shares may be converted into shares of Class A Common Stock or Common Stock, if the shares of any series are issued with the privilege of conversion; and

(f)

Whether or not shares shall have voting powers, and the terms and conditions upon which any voting powers may be exercised; provided that, so long as any Common Stock is outstanding, no Preferred Stock with voting powers shall have more than one vote per share nor shall any such Preferred Stock be entitled to vote with the Common Stock in the election of 33¹/3% of the members of the board of directors pursuant to paragraph (A)(2)(a) of this Article 4, on the removal of directors elected by holders of Common Stock pursuant to paragraph (A)(2)(b) of this Article 4, or in the filling of vacancies in the office of a director elected by holders of Common Stock pursuant to paragraph (A)(2)(d) of this Article 4.

B-8

Except as to the matters in respect to which variations are permitted under this subsection (B)(1), all series of the Preferred Stock of the corporation, whenever designated and issued, shall have the same rights, preferences and limitations and shall rank equally, share ratably and be identical in all respects as to all matters.

All shares of any one series of Preferred Stock established as hereinabove authorized shall be alike in every particular, and each series thereof shall be distinctively designated by letter or descriptive words or figures.

Any shares of Preferred Stock reacquired by the corporation by purchase or redemption, through conversion, or through the operation of any sinking fund or redemption or purchase account and which are thereafter cancelled shall have the status of authorized but unissued shares of Preferred Stock of the corporation, and, subject to the provisions of any series of the Preferred Stock, may thereafter be reissued as part of the same series or may be reclassified and reissued by the board of directors in the same manner as any other authorized but unissued shares of Preferred Stock.

(2)

Dividends.

Before any dividends, other than stock dividends, shall be paid or set apart for payment upon either the Class A Common Stock or the Common Stock, the holders of Preferred Stock shall be entitled to receive dividends at the rate per annum specified as to each series pursuant to paragraph (B)(1)(a), payable quarter-annually when and as declared by the board of directors.

Except as otherwise provided with respect to a particular series pursuant to paragraph (B)(1)(a), dividends shall accrue, in the case of shares of each particular series:

(i)

if issued prior to the record date for the first dividend on shares of such series, then from the date of initial original issue of shares of such series;

(ii)

if issued during the period commencing immediately after the record date for a dividend on shares of such series and terminating at the close of the payment date for such dividend, then from such last mentioned dividend payment date; and

(iii)

otherwise from the quarterly dividend payment date next preceding the date of original issue of such shares;

provided, that if the date of initial original issue of shares of any series shall be within thirty (30) days prior to the date when the first quarter-annual dividend would otherwise be payable, the board of directors may provide that such first dividend shall be payable only at the time of payment of the dividend for the next quarter-annual period, in which case no deficiency in payment of such first dividend shall exist by reason of such deferral.

All dividends of Preferred Stock shall be cumulative so that if the corporation shall not pay the quarterly dividend, or any part thereof, on the Preferred Stock then issued and outstanding, such deficiency in the dividend on the Preferred Stock shall thereafter be fully paid, but without interest, before any cash dividend shall be paid or set apart for payment on either the Class A Common Stock or the Common Stock.

Any dividend paid upon the Preferred Stock at a time when any accrued dividends for any prior period are delinquent shall be expressly declared as a dividend in whole or partial payment of the accrued dividend for the earliest period for which dividends are then delinquent, and shall be so designated to each shareholder to whom payment is made.

All shares of Preferred Stock shall rank equally and shall share ratably, in proportion to the rate of dividend fixed pursuant to paragraph (B)(1)(a) in respect to each such share, in all dividends paid or set aside for payment for any dividend period or part thereof upon any such shares.

B-9

(3)

Liquidation, Dissolution or Winding Up.

In case of voluntary or involuntary liquidation, dissolution or winding up of the corporation, the holders of shares of each series of Preferred Stock shall be entitled to receive out of the assets of the corporation in money or money’s worth the applicable amount specified pursuant to paragraph (B)(1)(c) with respect to that series of Preferred Stock, together with all accrued but unpaid dividends thereon (whether or not earned or declared), before any of such assets shall be paid or distributed to holders of Class A Common Stock or Common Stock, and if the assets of the corporation shall be insufficient to pay the holders of all of the Preferred Stock then outstanding the entire amounts to which they may be entitled, the holders of each outstanding series of the Preferred Stock shall share ratably in such assets in proportion to the amounts which would be payable with respect to such series if all amounts payable thereon were paid in full. The consolidating or merger of the corporation with or into any other corporation or corporations, or the merger of any other corporation or corporations into the corporation, in pursuance of the laws of the State of Delaware and of any other applicable state providing for consolidation or merger, shall not be deemed a liquidation, dissolution or winding up of the affairs of the corporation within the meaning of the foregoing provisions of this subsection (B)(3), unless otherwise provided pursuant to paragraph (B)(1)(c).

(C)

Preemptive Rights.

No holder of Preferred, Class A Common Stock or Common Stock shall be entitled, as of right because of his ownership of such stock, to subscribe for, purchase or receive any part of any new or additional issue of stock, whether Preferred Stock, Class A Common Stock or Common Stock, or of bonds, debentures or other securities convertible into stock, or any part of any reacquired shares or convertible securities held in treasury, but all such shares of stock or bonds, debentures or other securities convertible into stock may be issued and disposed of by the board of directors to such person or persons and on such terms and for such consideration (so far as may be permitted by law) as the board of directors in its absolute discretion may deem advisable. The provisions of this section (C) shall not impair any conversion right of any such convertible securities or any other right authorized by the board of directors to purchase or exchange, or to receive any distribution of, any securities of the corporation.

(D)

Special Voting Rights of Stockholders

(1) Subject to the voting rights of holders of Preferred Stock as may be established pursuant to subsection (B)(1) of this Article 4, the holders of Class A Common Stock and the holders of Common Stock shall be entitled to vote, and to vote as separate classes, upon the authorization of any amendment to this Certificate of Incorporation, and, in addition to the authorization of any such amendment by vote of a majority of the total number of votes represented by all outstanding shares entitled to vote thereon, the amendment shall be authorized by vote of a majority of the total number of votes represented by all outstanding shares of the Class A Common Stock and/or the Common Stock if such amendment contains any provision which would:

(a)

exclude or limit their right to vote on any matter, except as such right may be limited by voting rights given to new shares then being authorized of any existing or new class or series,

(b)

reduce the par value of their shares; or change their shares into a different number of shares of the same class or into the same or a different number of shares of any one or more classes or any series thereof, either with or without par value; or fix, change or abolish the designation or any of the relative rights, preferences and limitations of their shares, including any provision in respect to any undeclared dividends, whether or not cumulative or accrued, or the redemption of any shares, or any sinking fund for the redemption or purchase of their shares, or any preemptive right to acquire shares or other securities; or alter the terms or conditions upon which their shares are convertible or change the shares issuable upon conversion of their shares; if any such action would adversely affect such holders, or

B-10

(c)

subordinate their rights, by authorizing shares having preferences which would be in any respect superior to those rights.

(2) Any plan of merger or consolidation shall be adopted at a meeting of stockholders by a vote of two-thirds of the total number of votes represented by the outstanding shares entitled to vote thereon. The holders of shares of a class or series shall be entitled to vote and to vote as a class if the plan of merger or consolidation contains any provision which, if contained in an amendment to the Certificate of Incorporation, would entitle the holders of shares of such class or series to vote and vote as a class thereon pursuant to subsection (D)(1) of this Article 4. In such case, in addition to the authorization of the plan of merger or consolidation by vote of two-thirds of the total number of votes represented by all outstanding shares entitled to vote thereon, the plan of merger or consolidation shall be authorized by vote of the majority of the total number of votes represented by all outstanding shares entitled to vote thereon. Any plan of merger or consolidation of any subsidiary corporation or corporations, whether domestic or foreign, with and into the corporation shall not be subject to the provisions of this subsection (D)(2) if the corporation owns at least ninety percent of the outstanding shares of each class of capital stock of such subsidiary corporation or corporations.

For the purposes of this subsection (D)(2), the financial or other effect of any merger or consolidation on the corporation shall not be deemed to affect adversely the powers, preferences or rights of any class or series of stock.

(3) Any sale, lease, exchange or other disposition of all or substantially all the assets of the corporation, if not made in the usual or regular course of the business actually conducted by the corporation shall be authorized by vote at a meeting of stockholders of two-thirds of the total number of votes represented by all outstanding shares entitled to vote thereon.

(4) Any amendment to the Certificate of Incorporation of the corporation which adds a provision specifying that any stockholders, or the holders of any specified number or proportion of shares, or of any specified number or proportion of shares of any class or series thereof, may require the dissolution of the corporation at will or upon the occurrence of a specified event, or which changes or strikes out such a provision, shall be authorized at a meeting of stockholders by a vote of a majority of the total votes represented by all outstanding shares, whether or not otherwise entitled to vote on any such amendment.

(5) Any amendment to the Certificate of Incorporation of the corporation which changes or strikes out any provision specifying that the proportion of shares, or the proportion of shares of any class or series thereof, the holders of which shall be present in person or by proxy at any meeting of stockholders in order to constitute a quorum for transaction of any business or of any specified item of business, including amendments to this Certificate of Incorporation shall be greater than the proportion prescribed by law in the absence of such provision, or any provision specifying that the proportion of votes of the holders of shares, or of the holders of shares of any class or series thereof, that shall be necessary at any meeting of stockholders for the transaction of any business or of any specified item of business, including amendments to this Restated Certificate of Incorporation, shall be greater than such proportion prescribed by law in the absence of such provision, shall be authorized at a meeting of stockholders by vote of two-thirds of the total number of votes represented by all outstanding shares entitled to vote thereon.

A. O. Smith Corporation

11270 West Park Place

Milwaukee, WI 53224

Attention: James F. Stern

Ladies and Gentlemen:

Smith Investment Company, a Nevada corporation (“SICO”), Smith Investment Company LLC, a Delaware limited liability company (“SpinCo”), A. O. Smith Corporation (the “Company”), and SICO Acquisition, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (“Merger Sub”), are parties to an Agreement and Plan of Merger, dated as of the date hereof (as the same may be amended, supplemented, modified or waived from time to time, the “Merger Agreement”), providing for, among other things, the merger of SICO with and into Merger Sub (the “Merger”), in which all of the outstanding shares of common stock, par value $0.10 per share, of SICO held by the shareholders of SICO are being converted into a right to receive shares of Class A common stock, par value $5.00 per share, of the Company (“Class A Common Stock”) and shares of Common Stock, par value $1.00 per share, of the Company (“Common Stock”; and together with the Class A Common Stock, the “Company Common Stock”). Capitalized terms that are used but not otherwise defined in this support agreement (“Support Agreement”) will have the meanings ascribed to them in the Merger Agreement.

As a condition to the willingness of the Company to enter into and perform its obligations under the Merger Agreement, the Company has required that SICO enter into this Support Agreement. SICO is further entering into this Support Agreement to express its support for the Merger and the other transactions contemplated by the Merger Agreement.

In consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1. SICO represents and warrants that Schedule I annexed hereto sets forth as of the date hereof the number of shares of Company Common Stock owned beneficially or of record by SICO (the “Covered Shares”). SICO represents and warrants that, as of the date hereof and except as disclosed on Schedule II annexed hereto, SICO owns the Covered Shares free and clear of all liens, charges, encumbrances, voting agreements and commitments of every kind. As of the date of this Support Agreement, except as expressly permitted or provided in this Support Agreement or the Merger Agreement and except as disclosed on Schedule II annexed hereto, SICO has sole voting power and sole dispositive power with respect to all of the Covered Shares. SICO agrees, while this Support Agreement is in effect, to promptly notify the Company of the number of any new shares of Company Common Stock with respect to which SICO acquires beneficial or record ownership. Any such shares shall automatically become Covered Shares and subject to the terms of this Support Agreement as though owned by SICO as of the date hereof.

2. SICO has all necessary legal capacity, power and authority to execute and enter into this Support Agreement, and this Support Agreement is the legally valid and binding agreement of SICO, and is enforceable against SICO in accordance with its terms, subject to the Bankruptcy and Equity Exception.

3. SICO agrees that, during the term of this Support Agreement, it will not, and will not agree to, sell, transfer, assign, pledge, encumber or otherwise dispose of any of the Covered Shares, or any interest therein, or otherwise enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, encumbrance of other disposition of, or limitation on the voting rights of, any of the Covered Shares (any such action a “Transfer”); provided however, that nothing herein shall prevent SICO from consummating a Transfer (i) as specifically required by a court order, which SICO shall use its reasonable best

C-1

efforts to avoid, (ii) pursuant to this Support Agreement or the Merger Agreement or the transactions and other agreements contemplated thereby, or (iii) with the Company’s prior written consent. Any action taken in violation of the foregoing sentence shall be null and void ab initio and SICO agrees that any such prohibited action may and should be enjoined. If any involuntary Transfer of any of the Covered Shares shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold the Covered Shares subject to all of the restrictions, liabilities and rights under this Support Agreement, which shall continue in full force and effect until valid termination of this Support Agreement.

4. SICO agrees that, during the term of this Support Agreement, at any meeting of shareholders of the Company, however called, or any adjournment or postponement thereof, SICO shall be present (in person or by proxy) and vote (or cause to be voted) all of the Covered Shares (1) in favor of (a) the Merger and the other transactions contemplated thereby, including the Merger Agreement and (b) any other matter that is on the ballot in furtherance of or for the purpose of facilitating the Merger, including any matter that is required by law or regulatory authority to be approved by the stockholders of the Company to facilitate the Merger or any transaction contemplated by the Merger Agreement; and (2) against any proposal that would reasonably be expected to prevent or materially delay the consummation of the Merger.

5. SICO hereby agrees not to commence or participate in, and agrees to take all actions necessary to opt out of any class in any class action with respect to any claim, derivative or otherwise, against the Company, Merger Sub, or any of their respective successors relating to the negotiation, execution or delivery of this Support Agreement, the Merger Agreement or the consummation of the Merger, including any claim (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Support Agreement, the Merger Agreement or any transactions contemplated by the Merger Agreement, or (b) alleging a breach of any fiduciary duty of any officers or directors of the Company or Merger Sub in connection with this Support Agreement, the Merger or any of the transactions contemplated by the Merger, including the Merger Agreement. For the avoidance of doubt, the parties agree that this Paragraph 5 shall not preclude SICO from being a party to any litigation between or among the Company, Merger Sub, the Surviving Entity, SpinCo, the Shareholders’ Representative, any Smith Family Member or any other Former Company Shareholder concerning any provision of the Merger Agreement or any Ancillary Agreement or to resolve any dispute regarding any provision of the Merger Agreement or any Ancillary Agreement.

6. Whenever possible, each provision or portion of any provision of this Support Agreement will be interpreted in such manner as to be effective and valid under applicable law but if any provision or portion of any provision of this Support Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction, and this Support Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision or portion of any provision had never been contained herein.

7. Each of the parties hereto recognizes and acknowledges that a breach by SICO of any covenants or agreements contained in this Support Agreement will cause the Company to sustain damages for which it would not have an adequate remedy at law for money damages, and therefore each of the parties hereto agrees that in the event of any such breach the Company shall be entitled to the remedy of specific performance of such covenants and agreements and injunctive and other equitable relief in addition to any other remedy to which they may be entitled, at law or in equity.

8. Notwithstanding any other provision herein, the obligations of SICO set forth in this Support Agreement shall not be effective or binding until after such time as the Merger Agreement is executed and delivered by the Company, Merger Sub, SpinCo and SICO. This Support Agreement shall terminate immediately upon the earlier of (a) termination of the Merger Agreement in accordance with its terms, (b) the Parent Recommendation having been withdrawn or modified in a manner that would permit SICO to terminate the Merger Agreement in accordance with its terms, and (c) the Effective Time. Upon such termination, this Support Agreement shall

C-2

immediately become void, there shall be no liability hereunder on the part of SICO and all rights and obligations of the parties to this Support Agreement shall cease, in all cases so long as SICO is not in breach of its covenants or agreements under this Support Agreement; provided, however, that Paragraphs 5 through 14 hereof shall survive termination of this Support Agreement (it being understood that Section 7 shall survive solely to the extent necessary to effect the provisions of Section 5).

9. Any notice, request, instruction or other document to be given hereunder by any party to the other parties shall be in writing and shall be deemed to have been duly given on the next business day after the same is sent, if delivered personally or sent by telecopy or overnight delivery, or three calendar days after the same is sent, if sent by registered or certified mail, return receipt requested, postage prepaid, as set forth below, or to such other persons or addresses as may be designated in writing in accordance with the terms hereof by the party to receive such notice.

Ladies and Gentlemen:

Smith Investment Company, a Nevada corporation (“SICO”), Smith Investment Company LLC, a Delaware limited liability company (“SpinCo”), A. O. Smith Corporation, a Delaware corporation (the “Company”), and SICO Acquisition, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (“Merger Sub”), are parties to an Agreement and Plan of Merger, dated as of the date hereof (as the same may be amended, supplemented, modified or waived from time to time, the “Merger Agreement”), providing for, among other things, the merger of SICO with and into Merger Sub (the “Merger”), in which all of the outstanding shares of common stock, par value $0.10 per share, of SICO (“SICO Common Stock”) held by the shareholders of SICO are being converted into a right to receive shares of Class A common stock, par value $5.00 per share, of the Company and shares of Common Stock, par value $1.00 per share, of the Company. Each of the parties signatory hereto are stockholders of SICO (each, individually, a “Stockholder” and, collectively, the “Stockholders”). Capitalized terms that are used but not otherwise defined in this support agreement (“Support Agreement”) will have the meanings ascribed to them in the Merger Agreement.

As a condition to the willingness of the Company and SICO to enter into and perform their respective obligations under the Merger Agreement, the Company and SICO have required that each Stockholder enter into this Support Agreement. Each Stockholder is further entering into this Support Agreement to express its support for the Merger and the other transactions contemplated by the Merger Agreement.

In consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1. Each Stockholder represents and warrants that the list showing ownership by each of the Stockholders, provided to the Company and SICO (the “List”), sets forth as of the date hereof the number of shares of SICO Common Stock owned beneficially or of record by such Stockholder (the “Covered Shares”). Each Stockholder represents and warrants that, as of the date hereof, such Stockholder owns its Covered Shares free and clear of all liens, charges, encumbrances, voting agreements and commitments of every kind, except for such liens, charges, encumbrances, voting agreements and commitments that would not prevent or delay the performance by such Stockholder of its obligations under this Support Agreement or the transactions contemplated hereby. As of the date of this Support Agreement, except as expressly permitted or provided in this Support Agreement or the Merger Agreement and except as disclosed on the List, each Stockholder has sole voting power and sole dispositive power with respect to all of its Covered Shares. Each Stockholder agrees, while this Support Agreement is in effect, to endeavor to promptly notify the Company and SICO of the number of any new shares of SICO Common Stock with respect to which such Stockholder acquires beneficial or record ownership. Any such shares shall automatically become Covered Shares and subject to the terms of this Support Agreement as though owned by such Stockholder as of the date hereof.

D-1

2. Each Stockholder has all necessary legal capacity, power and authority to execute and enter into this Support Agreement, and this Support Agreement is the legally valid and binding agreement of such Stockholder, and, other than Paragraph 7 as to which the Stockholders make no representation, is enforceable against such Stockholder in accordance with its terms, subject to the Bankruptcy and Equity Exception.

3. Each Stockholder represents and warrants that (A) except for filings as may be required under, and other applicable requirements of, the Exchange Act, no filing with, and no permit, authorization, consent or approval of, any state, federal or foreign public body or authority is necessary for the execution of this Support Agreement by such Stockholder and the consummation by such Stockholder of the transactions contemplated hereby and (B) none of the execution and delivery of this Support Agreement by such Stockholder, the consummation by such Stockholder of the transactions contemplated hereby or compliance by such Stockholder with any of the provisions hereof shall (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, material modification or acceleration of any obligation or to a loss of a material benefit) under any of the terms, conditions or provisions of any contract, agreement or arrangement to which such Stockholder is a party or by which such Stockholder may be bound in a manner that would render such Stockholder unable to perform its covenants and agreements set forth in this Support Agreement, including any voting agreement, stockholders agreement, irrevocable proxy, voting trust or organizational document, or (ii) violate any law, order, injunction, judgment, decree or award of any court, Governmental Authority or arbitrator applicable to such Stockholder.

4. Each Stockholder agrees that, during the term of this Support Agreement, it will not, and will not agree to, sell, transfer, assign, pledge, encumber or otherwise dispose of any of the Covered Shares, or any interest therein, or otherwise enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, encumbrance of other disposition of, or limitation on the voting rights of, any of the Covered Shares (any such action a “Transfer”); provided however, that nothing herein shall prevent such Stockholder from consummating a Transfer (i) to another Stockholder, (ii) as specifically required by a court order, which such Stockholder shall use its reasonable best efforts to avoid, (iii) pursuant to this Support Agreement or the Merger Agreement or the transactions and other agreements contemplated thereby, (iv) as required by such Stockholder’s trust documents, or (v) with the Company’s and SICO’s prior written consent. Any action taken in violation of the foregoing sentence shall be null and void ab initio and each Stockholder agrees that any such prohibited action may and should be enjoined. If any involuntary Transfer of any of the Covered Shares shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold the Covered Shares subject to all of the restrictions, liabilities and rights under this Support Agreement, which shall continue in full force and effect until valid termination of this Support Agreement.

5. Each Stockholder agrees that, during the term of this Support Agreement, at any meeting of SICO stockholders, however called, or any adjournment or postponement thereof, such Stockholder shall be present (in person or by proxy) and vote (or cause to be voted) all of the Covered Shares (1) in favor of (a) the Merger and the other transactions contemplated thereby, including the Merger Agreement and (b) any other matter that is on the ballot in furtherance of or for the purpose of facilitating the Merger, including any matter that is required by law or regulatory authority to be approved by the stockholders of SICO to facilitate the Merger or any transaction contemplated by the Merger Agreement; and (2) against (X) any proposal that would reasonably be expected to prevent or materially delay the consummation of the Merger and (Y) any proposal directly resulting from or related to a Company Intervening Event that resulted in the modification or withdrawal of the Company Recommendation.

6. Each Stockholder further agrees that, during the one year period following any termination of the Merger Agreement by the Company pursuant to Section 8.1(e) of the Merger Agreement, at any meeting of SICO stockholders, however called, or any adjournment or postponement thereof, such Stockholder shall be present (in person or by proxy) and vote (or cause to be voted) all of the Covered Shares against any proposal directly resulting from or related to the Company Intervening Event that resulted in the modification or withdrawal of the Company Recommendation.

D-2

7. Each Stockholder hereby (i) waives, to the fullest extent of the law, and agrees not to assert any dissenters’ or appraisal rights in connection with the Merger, including pursuant to Section 92A.380 of the Nevada Revised Statutes or otherwise, with respect to any and all Covered Shares; and (ii) agrees not to commence or participate in, and agrees to take all actions necessary to opt out of any class in any class action with respect to any claim, derivative or otherwise, against the Company, Merger Sub, SICO or any of their respective successors relating to the negotiation, execution or delivery of this Support Agreement, the Merger Agreement or the consummation of the Merger, including any claim (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Support Agreement, the Merger Agreement or any transactions contemplated by the Merger Agreement, or (b) alleging a breach of any fiduciary duty of any officers or directors of the Company, Merger Sub or SICO in connection with this Support Agreement, the Merger or any of the transactions contemplated by the Merger, including the Merger Agreement. For the avoidance of doubt, the parties agree that this Paragraph 7 shall not preclude a Stockholder from being a party to any litigation between or among the Company, Merger Sub, SICO, the Surviving Entity, SpinCo, the Shareholders’ Representative, any Smith Family Member or any other Former Company Shareholder concerning any provision of the Merger Agreement or any Ancillary Agreement or to resolve any dispute regarding any provision of the Merger Agreement or any Ancillary Agreement.

8. Each Stockholder agrees that, except for filings under the Exchange Act or otherwise required by applicable Law, such Stockholder shall not issue any press release or make any public announcement relating to the subject matter of the Merger Agreement, whether prior to or following the termination of this Support Agreement, without the prior written consent of the Company and SICO.

9. Whenever possible, each provision or portion of any provision of this Support Agreement will be interpreted in such manner as to be effective and valid under applicable law but if any provision or portion of any provision of this Support Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction, and this Support Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision or portion of any provision had never been contained herein.

10. Each of the parties hereto recognizes and acknowledges that a breach by any Stockholder of any covenants or agreements contained in this Support Agreement will cause the Company and SICO to sustain damages for which it would not have an adequate remedy at law for money damages, and therefore each of the parties hereto agrees that in the event of any such breach the Company and SICO shall be entitled to the remedy of specific performance of such covenants and agreements and injunctive and other equitable relief in addition to any other remedy to which they may be entitled, at law or in equity.

11. Notwithstanding any other provision herein, the obligations of each Stockholder set forth in this Support Agreement shall not be effective or binding until after such time as the Merger Agreement is executed and delivered by the Company, Merger Sub, SpinCo and SICO. This Support Agreement shall terminate immediately upon the earlier of (a) termination of the Merger Agreement in accordance with its terms, (b) the Company Recommendation having been withdrawn or modified in a manner that would permit the Company to terminate the Merger Agreement in accordance with its terms, and (c) the Effective Time. Upon such termination, this Support Agreement shall immediately become void, there shall be no liability hereunder on the part of any Stockholder and all rights and obligations of the parties to this Support Agreement shall cease, in all cases so long as such Stockholder is not in breach of its covenants or agreements under this Support Agreement; provided, however, that Paragraphs 6 through 17 hereof shall survive termination of this Support Agreement (it being understood that Section 10 shall survive solely to the extent necessary to effect the provisions of Sections 6, 7 and 8).

D-3

12. Any notice, request, instruction or other document to be given hereunder by any party to the other parties shall be in writing and shall be deemed to have been duly given on the next business day after the same is sent, if delivered personally or sent by telecopy or overnight delivery, or three calendar days after the same is sent, if sent by registered or certified mail, return receipt requested, postage prepaid, as set forth below, or to such other persons or addresses as may be designated in writing in accordance with the terms hereof by the party to receive such notice.

WHEREAS, each Stockholder is a stockholder of SICO and will receive shares of Company Common Stock issued as consideration in the Merger;

WHEREAS, in considering the Merger, the Company has determined that it is advisable and in the best interests of the Company and its stockholders to condition its entry into the Merger on, among other things, the Stockholders’ agreement to certain standstill and other obligations set forth in this Agreement with respect to the affairs of the Company and the Company Common Stock; and

WHEREAS, in order to induce the Company to cause the Merger to be completed, the Stockholders have agreed to the standstill and other obligations set forth in this Agreement with respect to the affairs of the Company and the Company Common Stock.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Company, a form of which is appended to the Merger Agreement as Exhibit J), (B) in a “brokers transaction” (within the meaning of Rule 144 under the Securities Act) or (C) in any privately negotiated transaction that does not otherwise constitute a “tender offer” (within the meaning of Section 14(d) under the Exchange Act).

(b) “beneficially owns” (or comparable variations thereof) has the meaning set forth in Rule 13d-3 promulgated under the Exchange Act.

(c) “Bylaws” means the Amended and Restated Bylaws of the Company, as the same may be amended and restated from time to time.

(e) “Commission” means the Securities and Exchange Commission.

For purposes of this definition, “controlled by”, with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such Person, whether through the ownership of voting securities or by contract or otherwise.

(g) “Exchange Act” means the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.

(j) “Proxy Contest” means any “solicitation” of “proxies” (each within the meaning of Section 14(a) of the Exchange Act) by a Person other than a Stockholder, a Controlled Affiliate thereof, the Company or the Board of Directors of the Company with respect to any matter submitted for (i) consideration at any annual or special meeting of the stockholders of the Company or (ii) stockholder action by written consent.

(k) “Securities Act” means the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder.

E-2

meeting of the stockholders of the Company; provided however, that nothing herein shall restrict or limit the ability of (i) the holders of Class A Common Stock to solicit proxies or consents solely regarding matters affecting the rights, preferences or privileges of the Class A Common Stock that are exclusive to the Class A Common Stock and not shared with the holders of Company Common Stock, (ii) the holders of the Class A Common Stock, voting as a separate class or voting with the holders of Common Stock, to elect directors in accordance with the Certificate of Incorporation, or (iii) the Stockholders to vote their respective shares;

(b) Except in response to a Proxy Contest or otherwise if initiated or not opposed by the Company, initiate, knowingly participate in, or consent to the taking of any stockholder action by consent without a meeting pursuant to Section 228 of the DGCL; provided however, that nothing herein shall restrict or limit the ability of (i) the holders of Class A Common Stock to solicit consents, or to take action by written consent, solely regarding matters affecting the rights, preferences or privileges of the Class A Common Stock that are exclusive to the Class A Common Stock and not shared with the holders of Company Common Stock, or (ii) the holders of the Class A Common Stock, voting or acting as a separate class or voting or acting with the holders of Common Stock, to elect directors in accordance with the Certificate of Incorporation;

(c) Submit, otherwise solicit stockholder approval for, or take any action that would result in a public announcement related to, any proposal for consideration at any annual or special meeting of the stockholders of the Company (including pursuant to Rule 14a-8 under the Exchange Act);

(d) Make, effect or commence an Acquisition Transaction, or take any action that would reasonably be expected to result in a public announcement of an Acquisition Transaction;

(e) Enter into any agreements, arrangements or understandings with any other Person with respect to any matter described in this Section 1.02, including forming, joining or knowingly participating in a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to the Company or the Company Common Stock; provided, however, that nothing herein shall limit any Stockholder from forming, joining or participating in a “group” (i) comprised solely of the Stockholders and their respective Controlled Affiliates, (ii) created by entry into and the conduct of the Voting Trust Agreement, (iii) created as a result of any transaction undertaken for bona fide estate planning purposes, and/or (iv) created as a result of a transaction expressly permitted by this Agreement; or

(f) Except as provided in the Voting Trust Agreement, directly or indirectly sell, assign, gift, bequeath, appoint or otherwise dispose of any shares of Class A Common Stock to a Permitted Transferee unless the transferee is a Stockholder or becomes a party to this Agreement by executing a counterpart signature page to this Agreement.

The provisions of this Section 1.02 shall not impair or affect in any way the exercise by any Stockholder or any of its Controlled Affiliates of his or her fiduciary or other duties as a director, officer or employee of the Company in his or her capacity as such, nor shall any action in such capacity constitute a breach of this Agreement.

1.03 Stockholder Representations. Each Stockholder, severally and not jointly, hereby represents and warrants to the Company as follows:

(b) The execution and delivery by such Stockholder of this Agreement do not, and the performance by such Stockholder of such Stockholder’s obligations under this Agreement will not: (i) conflict with or result in a violation or breach of any term or provision of any law, statute, rule or regulation or any order,

Annex F

FORM OF ESCROW AGREEMENT

This Escrow Agreement (this “Escrow Agreement”), is dated as of , 2009, by and among Smith Investment Company LLC, a Delaware limited liability company, not individually but solely in its capacity as nominee for the Former SICO Shareholders as provided in the Merger Agreement (as defined below) (the “Shareholders’ Representative”), A.O. Smith Corporation, a Delaware corporation (the “Company”), Smith Investment Company LLC, a Delaware limited liability company, in its individual capacity (“SpinCo”), and , as escrow agent (the “Escrow Agent”).

The Company, SpinCo, Smith Investment Company, a Nevada corporation (“SICO”), and SICO Acquisition, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Company (“Merger Sub”), are parties to an Agreement and Plan of Merger, dated as of December 9, 2008 (the “Merger Agreement”), providing for, among other things, the merger of SICO with and into Merger Sub, with Merger Sub as the entity surviving the Merger (the “Merger”). In the Merger, the outstanding shares of common stock, par value $0.10 per share, of SICO (the “SICO Common Stock”), other than shares to be cancelled in accordance with the Merger Agreement and Dissenting Shares, held by the shareholders of SICO (the “Former SICO Shareholders”) are being converted into a right to receive shares of Class A common stock, par value $5.00 per share, of the Company (“Class A Common Stock”) and shares of Common Stock, par value $1.00 per share, of the Company (“Common Stock,” and together with the Class A Common Stock, the “New Shares”). If a holder of Dissenting Shares fails to perfect or effectively withdraws or loses its rights to appraisal of such Dissenting Shares and its shares of SICO Common Stock are converted into the right to receive New Shares in accordance with the Merger Agreement, then such holder of Dissenting Shares shall be deemed to be a Former SICO Shareholder for all purposes of this Escrow Agreement. Capitalized terms used but not otherwise defined in this Escrow Agreement have the respective meanings given to them in the Merger Agreement. This is the Escrow Agreement contemplated by Section 2.3 of the Merger Agreement.

Pursuant to the Merger Agreement, the Company is depositing with the Escrow Agent a number of shares of Common Stock otherwise deliverable pursuant to the Merger to the Former SICO Shareholders that is equal to (a) $15,000,000, divided by (b) the Market Value of a share of Common Stock, determined as of the date of this Escrow Agreement, rounding to the nearest whole share (rounding upward in the case of any 0.5 of a share) (the “Escrowed Shares”). In addition, SpinCo may deposit with the Escrow Agent from time to time after the date of this Escrow Agreement, cash to obtain the release of the Escrow Shares in accordance with Section 3(d) below (any cash so deposited with the Escrow Agent, the “Escrowed Cash”; and, together with the Escrowed Shares, the “Escrow Fund”). The Escrow Fund shall be held in escrow by the Escrow Agent for the purpose of providing a fund to reimburse the Parent Indemnified Parties for the payment of any Damages for which the Parent Indemnified Parties are entitled to indemnification pursuant to the terms of Article VII of the Merger Agreement. For purposes of this Escrow Agreement, the “Market Value” of a share of Common Stock as of any date of determination shall be the average of the volume-weighted average price of trades for a share of Common Stock on the New York Stock Exchange for the ten trading days ending on the last trading day immediately preceding such date of determination.

For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

Establishment of Escrow.

(a) Pursuant to the Merger Agreement, at the Effective Time, the Company shall, on behalf of the Former SICO Shareholders, deposit with the Escrow Agent stock certificates representing the Escrowed Shares or a book-entry with respect to the Escrow Shares in the Escrow Agent’s account. In addition, SpinCo may, on its own behalf, deposit with the Escrow Agent from time to time after the date of this Escrow Agreement Escrowed Cash in accordance with Section 3(d) below.

(b) Unless and until delivered to the Company in accordance with the terms hereof, that number of Escrowed Shares (and the certificates representing such Escrowed Shares) equal to each Former SICO Shareholder’s Pro Rata Percentage (as defined below) of the Escrowed Shares shall be registered in the

F-1

name of such Former SICO Shareholder. Each Former SICO Shareholder’s “Pro Rata Percentage” shall be equal to (i) the number of shares of SICO Merger Stock held by such Former SICO Shareholder, divided by (ii) the total number of shares of SICO Merger Stock held by all Former SICO Shareholders, rounding to the nearest one one-thousandth (rounding upward in the case of any .0005). Unless and until delivered to the Company in accordance with the terms hereof, any Escrowed Cash shall be held in the name and for the benefit of SpinCo. For purposes of this Section 1(b), “SICO Merger Stock” shall mean each share of SICO Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be cancelled in accordance with the Merger Agreement and Dissenting Shares).

(c) The Former SICO Shareholders (with respect to any Escrowed Shares) and SpinCo (with respect to any Escrowed Cash) shall be entitled to receive and be paid any and all dividends, interest or other earnings earned on the Escrowed Shares or the Escrowed Cash prior to delivery of the applicable Escrowed Shares to the Shareholders’ Representative or the Company, as applicable, or the Escrowed Cash to SpinCo or the Company, as applicable, in accordance with the terms hereof (the “Earnings”). If the Escrow Agent receives any Earnings, then the Escrow Agent promptly shall distribute and disburse such Earnings to the Shareholders’ Representative for distribution to the Former SICO Shareholders in accordance with their Pro Rata Percentage (with respect to Earnings on any Escrowed Shares) or to SpinCo (with respect to Earnings on any Escrowed Cash). Any Earnings with respect to the Escrow Fund shall be the sole and exclusive property of the Former SICO Shareholders (with respect to Earnings on any Escrowed Shares) and SpinCo (with respect to Earnings on any Escrowed Cash).

(d) The parties hereby designate and appoint the Escrow Agent to serve in accordance with the terms, conditions and provisions of this Escrow Agreement, and the Escrow Agent hereby agrees to act as escrow agent and to hold in trust, safeguard, invest and disburse the Escrow Fund, pursuant to the terms and conditions hereof.

(e) Voting and granting consents with respect to any Escrowed Shares shall be as determined by the Former SICO Shareholder in whose name such Escrowed Shares are registered in such Former SICO Shareholder’s absolute discretion; provided that the foregoing shall not affect the obligation of the parties to the Stockholder Agreement to comply with their contractual obligations thereunder with respect to such Escrowed Shares.

(f) To the extent that any portion of the Escrow Fund consists of Escrowed Cash, the Escrow Agent shall invest and reinvest such Escrowed Cash portion of the Escrow Fund at the joint written instructions of the Company and the Shareholders’ Representative. In the absence of joint written instructions from the Company and the Shareholders’ Representative, any Escrowed Cash shall be invested in direct obligations of or obligations fully guaranteed by the United States of America or any agency or instrumentality thereof which have a maturity of ninety (90) days or less.

Indemnification Claims.

(a) A Claim for Damages to be paid from the Escrow Fund pursuant to Article VII of the Merger Agreement may be made only if the Company delivers to the Shareholders’ Representative (with a copy to the Escrow Agent) on or prior to the Escrow Release Date (as defined in Section 3(a)) a Claim Notice satisfying the requirements of the Merger Agreement (the amount of any Damages in any such Claim Notice, the “Indemnification Amount”). If, within thirty (30) days following receipt by the Shareholders’ Representative of a Claim Notice, the Shareholders’ Representative gives notice (a “Counter Notice”) to the Company (with a copy to the Escrow Agent) disputing the applicable Parent Indemnified Party’s entitlement to indemnification with respect to the Claim set forth in a Claim Notice or disputing the estimate set forth in such Claim Notice of the dollar amount of the Damages for which the Parent Indemnified Party is entitled to indemnification pursuant to the terms of the Merger Agreement, the applicable Parent Indemnified Party’s entitlement to indemnification with respect to the Claim and the dollar amount of the Damages for which the Parent Indemnified Party is entitled to indemnification pursuant to the terms of the Merger Agreement shall be resolved as provided in Section 2(c) below.

F-2

(b) If no Counter Notice is received by the Escrow Agent within such thirty (30) day period, then the Indemnification Amount claimed in the applicable Claim Notice shall be deemed established for purposes of this Escrow Agreement, and, at the end of such thirty (30) day period, the Escrow Agent shall promptly (but in any event within three Business Days) deliver to the Company from the Escrow Fund (i) Escrowed Cash in an amount equal to the Indemnification Amount as claimed in the Claim Notice and (ii) if the Escrowed Cash is not sufficient to satisfy the Indemnification Amount, Escrowed Shares with an aggregate Market Value equal to the unsatisfied Indemnification Amount, with the Market Value of such Escrowed Shares to be determined as of the date of delivery of any Escrowed Shares to the Company. Any Escrowed Shares so delivered to the Company from the Escrow Fund shall be disbursed from the Escrowed Shares of the Former SICO Shareholders proportionally in accordance with their respective Pro Rata Percentages.

(c) (i) If a Counter Notice is given by the Shareholders’ Representative with respect to a Claim, the Escrow Agent shall promptly (but in any event within three Business Days) deliver to the Company from the Escrow Fund the appropriate amount of Escrowed Cash and/or Escrowed Shares in respect of such Claim in the order set forth in Section 2(b) only in accordance with (A) joint written instructions of the Company and the Shareholders’ Representative, or (B) a final judgment with no further right to appeal, upon an award rendered by a court of competent jurisdiction.

(ii) If the Company and the Shareholders’ Representative are unable to resolve any dispute within thirty (30) days of the Shareholders’ Representative’s delivery of a Counter Notice, such dispute shall be resolved in accordance with Section 9.6 of the Merger Agreement or by means of a settlement reached between the Shareholders’ Representative and the Company with respect to the applicable Claim.

(d) If the Shareholders’ Representative and the Company reach a settlement with respect to any Claim made by the Company or if the amount of Escrowed Cash and/or Escrowed Shares to be disbursed in respect of a Claim is determined through a judgment not subject to appeal as provided in Section 2(c), the Shareholders’ Representative and the Company shall jointly deliver written notice of such settlement or judgment to the Escrow Agent, including (if applicable) instructions to the Escrow Agent to disburse the appropriate number of Escrowed Cash and/or Escrowed Shares to the Company in the order set forth in Section 2(b), and the Escrow Agent shall act promptly in accordance with such instructions.

(e) To the extent the Escrow Agent is otherwise required hereunder to disburse a fractional Escrowed Share of a Former SICO Shareholder, the Escrow Agent shall round down such fractional share to the nearest whole share.

(f) The Escrow Agent shall requisition from the Company’s stock transfer agent stock certificates in appropriate denominations registered as appropriate to facilitate the delivery or disbursement by the Escrow Agent of Escrowed Shares hereunder. The Company shall cause its stock transfer agent to cooperate with the Escrow Agent in connection therewith.

Termination of Escrow.

(a) On the first Business Day following the date that is twenty-four (24) months after the Closing (the “Escrow Release Date”), unless any Claims have previously been asserted by delivery of a Claim Notice in accordance with Section 2(a) and continue to be pending, in which event any disbursement with respect to the Indemnification Amount of such Claim will be governed by Section 3(c), the Escrow Agent shall promptly disburse all Escrowed Shares in the Escrow Fund to the Shareholders’ Representative for distribution to the Former SICO Shareholders in accordance with their respective Pro Rata Percentages, and all Escrowed Cash in the Escrowed Fund to SpinCo.

(b) Notwithstanding anything to the contrary in Section 3(a), if prior to the Escrow Release Date, there is a Resolution of Transaction-Related Claims, the Company and the Shareholders’ Representative shall provide joint written instructions to the Escrow Agent authorizing the Escrow Agent to distribute (i) first, Escrowed Shares to the Shareholders’ Representative, for distribution to the Former SICO Shareholders in accordance with their Pro Rata Percentage, and (ii) second, Escrowed Cash to SpinCo, so that after giving effect to any such distribution, there remains in the Escrow Fund a combination of Escrowed Shares and

F-3

Escrowed Cash having aggregate value of $7,500,000, plus an amount equal to the amount by which the aggregate Indemnification Amount of any pending Claims exceeds $3,000,000, with the Market Value of any Escrowed Shares to be determined as of the date of Resolution of Transaction-Related Claims. For purposes of this Escrow Agreement, “Resolution of Transaction-Related Claims” shall mean that as of the 60th day after the date of this Escrow Agreement, no Transaction-Related Claims are pending or, if as of the 60th day after the date of this Escrow Agreement, one or more Transaction-Related Claims are pending, all such Transaction-Related Claims have thereafter been settled by the applicable parties thereto or there has been a final judgment with no further right to appeal by a court of competent jurisdiction with respect to such Transaction-Related Claims and all the indemnification obligations related to such Transaction-Related Claims as set forth in the Merger Agreement have been satisfied.

(c) If any Claims were asserted by delivery of a Claim Notice in accordance with Section 2(a) prior to the Escrow Release Date with respect to such Claims and such Claims continue to be unresolved as of the Escrow Release Date, the Escrow Agent shall exclude from the disbursement of Escrowed Shares and Escrowed Cash in accordance with Section 3(a), and shall continue to hold in the Escrow Fund hereunder, that amount of (i) first, Escrowed Cash and (ii) second, Escrowed Shares, so that there remains in the Escrow Fund a combination of Escrowed Cash and Escrowed Shares having aggregate value equal to 110% of the aggregate Indemnification Amounts (such aggregate amount, the “Indemnification Holdback Amount”), with the Market Value of any Escrowed Shares to be determined as of the Escrow Release Date. After the Escrow Release Date, the Escrow Agent shall disburse the Indemnification Holdback Amount from the Escrow Fund as and to the extent the Claims with respect thereto are resolved in accordance with the provisions of Section 2(d) of this Escrow Agreement, with such disbursement made first to the Company in the amount of any such resolved Claim and second to the Shareholders’ Representative or SpinCo, as applicable, with respect to any excess Indemnification Holdback Amount with respect to such Claim.

(d) SpinCo shall have the right from time to time and at any time (including after the Escrow Release Date with respect to the Indemnification Holdback Amount), but not more than five times in total, to substitute in the Escrow Fund cash for all or a portion of the then remaining Escrowed Shares, such cash to be considered part of the Escrowed Cash for all purposes under this Escrow Agreement. In the event of any such election by SpinCo, upon the deposit by SpinCo of cash with the Escrow Agent, the Escrow Agent shall distribute Escrowed Shares to the Shareholders’ Representative, for distribution to the Former SICO Shareholders in accordance with their respective Pro Rata Percentages, having an aggregate Market Value equal to the amount of the cash deposited by SpinCo, with the Market Value of any such Escrowed Shares to be determined as of the date of this Escrow Agreement.

Duties of Escrow Agent.

(a) The Escrow Agent shall not be under any duty to give the Escrow Fund held by it hereunder any greater degree of care than it gives its own similar property.

(b) The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof. The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume that the person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so.

(c) The Escrow Agent shall provide the Shareholders’ Representative, SpinCo and the Company with quarterly reports of the status of the Escrow Fund, and shall permit the Shareholders’ Representative and representatives of the Company and SpinCo to inspect and obtain copies of the records of the Escrow Agent regarding the Escrow Fund, during normal business hours and upon one Business Day’s prior written notice.

(g) The Escrow Agent shall not be called upon to advise any party as to the wisdom in selling or retaining or taking or refraining from any action with respect to any securities or other property deposited hereunder.

(h) The Escrow Agent may resign as the Escrow Agent by notice to the other parties hereto (the “Resignation Notice”).

Upon the appointment of a successor escrow agent and the transfer of the Escrow Fund thereto, the duties of the Escrow Agent hereunder shall terminate.

The parties hereto other than the Escrow Agent further agree to pursue any redress or recourse in connection with such a dispute, without making the Escrow Agent a party to same.

(j) The Escrow Agent shall never be required to use or advance its own funds or otherwise incur personal financial liability in the performance of any of its duties or the exercise of any of its rights and powers hereunder.

(k) The Escrow Agent shall have the right to perform any of its duties hereunder through agents, attorneys, custodians or nominees selected in good faith.

(l) Any banking association or corporation into which the Escrow Agent may be merged, converted or with which the Escrow Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Escrow Agent shall be a party, or any banking association or corporation to which all or substantially all of the corporate trust business of the Escrow Agent shall be transferred, shall succeed to all the Escrow Agent’s rights, obligations and immunities hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

(m) This Escrow Agreement expressly sets forth all the duties of the Escrow Agent, which shall be deemed purely ministerial in nature with respect to any and all matters pertinent hereto. The Escrow Agent shall under no circumstance be deemed a fiduciary for any of the parties to this Escrow Agreement. No implied duties or obligations shall be read into this Escrow Agreement against the Escrow Agent.

Annex G

FORM OF SMITH FAMILY

VOTING TRUST AGREEMENT

This Voting Trust Agreement (“Agreement”) is made as of the day of , 2009, between the persons whose signatures are hereunto affixed as depositors, and such other qualified persons as shall become parties hereto from time to time as hereinafter provided (the “Depositors”), and , , and , and their successors, as Trustees (the “Trustees”).

WITNESSETH:

WHEREAS, as former shareholders of Smith Investment Company, a Nevada corporation (“SICO”), and Smith Family Members (as defined below), the Depositors have received or will receive, in the merger (the “Merger”) of SICO into a subsidiary of A.O. Smith Corporation, a Delaware corporation (“AOS”), shares of AOS Common Stock (“Common Stock”) and Class A Common Stock (“Class A Stock”); and

WHEREAS, the Depositors deem it advisable and in their best interests, in order to insure harmony and agreement among themselves as to the investment in AOS and to protect their collective interests in AOS, to deposit their shares of Common Stock and Class A Stock (collectively, “Shares”) with the Trustees pursuant to this Agreement;

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Depositors and the Trustees do hereby agree as follows:

I.	DEPOSIT OF SHARES; GENERAL PROVISIONS

1. Transfer of Shares to Trustees. The undersigned Depositors, holding the number of Shares set opposite their respective names on the addendum to the signature page to this Agreement, shall deposit said Shares, and any additional Shares which they may receive upon termination of the escrow arrangements pursuant to the Merger, with the Trustees, properly endorsed for assignment and transfer to the Trustees on the books of AOS. The Shares so deposited with the Trustees shall be surrendered to AOS and cancelled and new certificates therefor shall be issued to the Trustees stating that they are issued pursuant to the Smith Family Voting Trust (“Trust”), created by this Agreement, which fact shall also be stated in the stock ledger of AOS.

2. Effect. The deposit of Shares with the Trustees hereunder shall constitute assignment and transfer to the Trustees of full legal title to such Shares, and shall vest in the Trustees all rights and powers of every nature incident to ownership of such Shares subject only to the limitations specifically set forth herein.

3. Depositors. Any holder of Common Stock or Class A Stock who is a Smith Family Member, as defined in the Amended and Restated Certificate of Incorporation of AOS as adopted by its stockholders on , 2009 (the “AOS Certificate”) may become a Depositor and thereby a party to this Agreement at any time, with the consent of the Trustees, by executing and delivering to the Trustees a deposit letter in substantially the form hereto annexed as Exhibit “A” and by depositing the certificates representing Shares owned by the Depositor, duly authorized for transfer, with the Trustees, together with a sum sufficient to cover any governmental charges incidental to such transfer. The Trustees shall have the sole discretion to determine whether an individual is eligible to be a Depositor pursuant to this Agreement. Each Depositor, by the deposit of his or her Shares hereunder, shall, as of the date of deposit, become a party to and be bound by all the terms and provisions of this Agreement with the same effect as if an initial Depositor hereunder. Any Depositor may, at any time or from time to time following the initial deposit of Shares hereunder, deposit additional Shares.

4. Trust Interests. The Shares deposited hereunder shall be held for the account of each respective Depositor. Trust certificates for said Shares will not be issued. For purposes of this Trust Agreement, the beneficial interests of Depositors or Beneficiaries in Shares held by the Trust for their respective accounts shall be referred to herein as “Trust Interests”.

G-1

5. Certificate of Intent. Each Depositor may file a Certificate of Intent in substantially the form hereto annexed as Exhibit “B,” signifying an intent by the Depositor to purchase additional shares of Common Stock or (if permitted by the AOS Certificate without their conversion into shares of Common Stock) Class A Stock pursuant to the terms and conditions herein. A Depositor may amend his Certificate of Intent to reflect any change in the Depositor’s interest or ability to purchase additional stock.

6. Beneficiary. The term “Beneficiary,” as used in this Agreement, shall mean a holder of record on the books of the Trustees of Trust Interests granted hereunder (whether held by initial deposit or by permitted transfer), and shall be construed to mean and include not only such holders and owners acting in their own right but also any person, association, or corporation possessing Trust Interests in a representative or fiduciary capacity. Although a Depositor is a Beneficiary, a Beneficiary may not necessarily be a Depositor.

II.

DIVIDENDS; ADDITIONAL STOCK AVAILABILITY

1. Payment of Dividends. In the event the Trustees receive any dividend or other distribution of cash or property (other than Common Stock, Class A Stock or other securities which may become AOS voting stock upon the happening of any specified contingency) upon or by reason of the Shares held by the Trustees hereunder, the Trustees shall promptly make a pro rata distribution (based on number and class of shares held in each Beneficiary’s account) of such dividend or distribution to the Beneficiaries as their respective Trust Interests appear on the books of the Trustees as of the record date of the dividend or distribution. In the event of a stock split-up, or dividend or distribution of Common Stock, Class A Stock or other securities that may become voting stock, such stock shall be added to the Shares held by the Trustees hereunder and the Trust Interests of Beneficiaries shall be adjusted accordingly. Prior to making any distribution of cash, securities or other property to the Beneficiaries, the Trustees may retain therefrom a sufficient part, either in cash, securities or property, to meet the expenses and obligations of the Trust; provided, however, that the Trustees may not sell or otherwise dispose of Common Stock, Class A Stock or other voting securities for the purpose of meeting such expenses or obligations except in compliance with the procedure outlined in Paragraph 3 of Part V hereof. The Trustees may, in their discretion, from time to time, instead of receiving and distributing any such dividends or distributions, authorize AOS to make payment or delivery thereof directly to the Beneficiaries. The Trustees may also withhold taxes from the distributions to any Beneficiary as may be required by applicable law or regulation.

2. Subscription Rights. The Trustees shall promptly give notice to the Beneficiaries of the issuance or granting by AOS to its stockholders of any warrants or rights to subscribe to any security to be issued by AOS, and each such Beneficiary shall have the right, upon furnishing adequate funds and complying with other terms or provisions of such warrants or rights, to direct the Trustees to exercise such warrants or rights, or any part thereof, in respect of the Shares represented by the Trust Interests possessed by such Beneficiary. The Trustees shall hold and own, subject to the provisions hereof, all voting stock and all stock convertible into voting stock issued upon exercise of such warrants or rights, and shall adjust in respect thereof the Beneficiaries’ Trust Interests accordingly.

3. Purchases by Trust. The Trustees shall be entitled to purchase Common Stock or Class A Stock (or rights thereto) directly from AOS or from sources other than AOS on behalf of Depositors to the extent made available to the Trust from time to time; provided, however, that the Trust shall not purchase any such stock in excess of the amount indicated on the Depositors’ Certificates of Intent, so that at no time will the Trust purchase or own Shares for its own account. In the event the Trust has the opportunity to purchase stock in excess of the Depositors’ current expressions of interest, the Trustees may, in their discretion, notify the Depositors of such opportunity. Any Depositor, in response to such notice, desiring to amend his Certificate of Intent in order to purchase stock in addition to the amount previously set forth in his Certificate of Intent shall file a written request with the Trustees during the time frame indicated by the Trustees. The Trustees shall promptly notify the Depositors of stock purchases, and the Depositors shall promptly make payment therefor at the time and in such manner specified by the Trustees. Any stock purchased by the Trust shall be distributed to the accounts of the Depositors on a pro rata basis, in accordance with the Certificates of Intent filed by the Depositors or in such other manner as the Trustees deem fair and equitable; provided, however, that the allocation of Shares may be adjusted by the Trustees in favor of purchasers who do not need to borrow funds to finance their purchases.

G-2

4. Common/Class A Exchanges. Unless directed to the contrary in a Depositor’s Certificate of Intent, and other than in respect of any Depositor which is not eligible under the AOS Certificate to purchase additional shares of Class A Stock without their conversion into shares of Common Stock, the Trustees may use and/or exchange Common Stock held by the Trust as consideration for the purchase of Class A Stock available to the Trust from time to time. Any such exchanges shall be on such terms and conditions as deemed reasonable by the Trustees and shall be made on a pro rata basis based on each Beneficiary’s Trust Interests attributable to Class A Stock or pursuant to such other method as the Trustees deem fair and equitable.

5. Reorganization. If, in case of reorganization, merger, consolidation or other similar change in AOS, the Trustees receive stock or other equity securities in any reorganized, merged, consolidated, new or different corporation in exchange for the Shares deposited or held hereunder, the Trustees may in their discretion hold the securities so received or may distribute such securities to the Beneficiaries as their respective Trust Interests appear on the Trustees’ records. With respect to securities exchanged or substituted for the Shares represented by outstanding Trust Interests, the rights and obligations of the Trustees and Beneficiaries shall, for all purposes, be treated as applying to the securities so held in exchange or substitution.

III.

TRUSTEE ACTIONS; POWERS

1. Powers. The Trustees, with respect to the Shares held hereunder, are hereby vested as owners of such Shares (without limitation except as herein otherwise expressly provided) with all of the rights, powers and privileges of every kind and character of an owner thereof, including, without limiting the generality of the foregoing: (a) the right to vote the same, either in person or by proxy, for every purpose; (b) the right to become parties to or prosecute or intervene in any suits or other legal or administrative proceedings affecting (i) the Shares held hereunder, (ii) AOS, or (iii) the powers and duties or obligations of the Trustees; (c) the right to transfer all or any part of the Shares held hereunder into their names as Trustees or into the name or names of the nominee or nominees; (d) the right to exchange Shares of Common Stock held hereunder for Shares of Class A Stock; and (e) the right to borrow or to arrange for borrowing for the purpose of purchasing additional stock, including the right to pledge the Shares held hereunder as security for said borrowing(s). The obligations and agreements of the Trustees shall not be binding upon the Trustees personally but shall bind solely the Shares and other assets and property in the hands of the Trustees.

2. Voting. In voting the Shares held hereunder, the Trustees shall exercise their best judgment and may take such part or action with respect to the management of the affairs of AOS as they deem appropriate or necessary, subject to the obligations of the Depositors under the Stockholder Agreement dated December 9, 2008 by and among AOS and the various Smith Family Members who are signatories thereto.

3. Trustee Status. Any Trustee, individually or otherwise, may hold Common Stock, Class A Stock or other securities of AOS or possess Trust Interests issued hereunder and, individually or as a Trustee, may vote for himself as a director of AOS; and any Trustee, or any firm of which he is a member, or a corporation in which he is a stockholder or officer or in which he may be otherwise interested, may contract with AOS or the Trustees or be or become pecuniarily interested in any matter or transaction to which AOS or the Trustees may be a party, as fully as though such person were not a Trustee hereunder. A Trustee, if a director of AOS, may vote for himself as an officer and/or employee of AOS and may participate in fixing the amount of compensation for such services. Any Trustee who is also a Beneficiary or a Depositor shall have all rights accorded Beneficiaries or Depositors hereunder.

4. Majority to Act. Except as otherwise herein provided, any action to be taken hereunder by the Trustees shall require the approval of a majority of the Trustees then qualified as Trustees and acting hereunder. In the event that a majority of the Trustees are unable to agree upon any issue, the Trustees shall act in accordance with the decision of the majority of a board of three arbitrators, one each to be appointed by the opposing Trustees and the third to be appointed by the other two arbitrators so selected.

G-3

5. Expenses. The Trustees may incur and pay all expenses and disbursements which the Trustees may deem necessary or proper in and about exercising the powers of authority given to or vested in the Trustees by this Agreement, and shall be entitled to reimbursement for any expenses and obligations incurred by them by reason of this Trust, as provided in Paragraph 1 in Part II above. The Trustees shall not be entitled to compensation for services rendered as Trustees.

6. Records and Reports.

(a) The Trustees shall keep proper records of Trust assets, receipts and disbursements, a list of Beneficiaries and the Shares in their accounts, and other records connected with the administration of this Trust. The books and records of the Trustees containing the accounts and names of Beneficiaries shall at all reasonable times be open to inspection by the Beneficiaries for any proper purpose.

(b) The Trustees shall periodically prepare and transmit to each Beneficiary statements of such Beneficiary’s account, showing the number of shares of Common Stock and/or Class A Stock held on behalf of the Beneficiary, recent activity in such account, and such other matters as the Trustees deem appropriate.

(c) Upon the written request of a Beneficiary, the Trustees shall issue and mail annual financial reports to such Beneficiary within thirty (30) days after the final adjournment of each annual meeting of the stockholders of AOS and may, in their discretion, issue and mail to Beneficiaries interim financial reports. Financial reports shall include information of such nature and scope as the Trustees shall deem relevant and appropriate under the circumstances. Unless formal notice questioning the adequacy and accuracy of such financial reports is filed with the Secretary within thirty (30) days after the mailing of any such report, such report as against all Beneficiaries requesting such report shall be conclusively presumed to be in all respects correct.

(d) The Trustees shall promptly transmit all communications from AOS received by the Trustees as AOS stockholders to the Beneficiaries.

7. Secretary. The Trustees shall appoint a Secretary and an Assistant Secretary (herein referred to as the “Secretary” and “Assistant Secretary”), either of whom may but need not be a Trustee. The Trustees may remove or replace at any time the persons who are appointed as Secretary and Assistant Secretary, and may pay reasonable compensation to the Secretary and/or the Assistant Secretary, if said persons are not Trustees. It shall be the duty of the Secretary to keep the minutes of meetings of the Trustees and to maintain a record of transactions hereunder and to perform such other duties as herein provided or as may be required by the Trustees. The Assistant Secretary shall act in place of the Secretary in taking any action or performing any duties herein required to be taken or performed by the Secretary whenever the Secretary shall be incapacitated, absent, or for any other reason unable to act. Promptly upon appointment, the Secretary shall give notice in writing to all Beneficiaries of his name and address, and the name and address of the Assistant Secretary, and shall give similar notice of any change therein.

IV.

SALE OF STOCK BY THE TRUSTEES

Whenever Beneficiaries possessing Trust Interests representing in the aggregate at least seventy-five percent (75%) of all the votes as determined by the voting power of the Shares held hereunder direct the sale as a unit of all or any part of the Shares for such price and upon such terms or in exchange for such other property that they shall agree upon, then the Trustees shall make the sale of such Shares as so directed, whether or not the Trustees or other Beneficiaries approve the sale. Likewise, if at any time the Trustees unanimously authorize such action, the Trustees, with the written consent of Beneficiaries holding Trust Interests representing in the aggregate a majority of the voting power of all of the Shares held hereunder, may sell as a unit all or any part of the Shares for such price and upon such terms or in exchange for such other property as they in their discretion deem proper. If such a sale is of all of the Shares then held hereunder, this Agreement may be terminated in the discretion of the Trustees, and the Trustees may distribute the assets in their hands in accordance with the provisions of Paragraph 4 of Part VII hereof. If such sale is of only part of the Shares then held hereunder, then the Shares so

G-4

sold shall be selected by the Trustees pro rata from the Shares of all Beneficiaries, as their respective interests shall appear on the Trustees’ books, and the proceeds of such sale shall be distributed to the Beneficiaries in the same manner; provided, that if such sales are made in exchange for other stocks or securities of any corporation, the Trustees, in their discretion, may retain such stock or securities, and thereafter the rights and obligations of the Trustees and Beneficiaries shall, for all purposes, be treated as applying to the stock or securities so received in exchange.

V.	*TRANSFER OF TRUST INTERESTS AND SHARES*

1. Transfer Books. The Trust Interests issued hereunder shall be transferable only on the books of the Trustees, subject to such regulations as the Trustees may institute and upon compliance with this Part V, and the Trustees may at all times and for all purposes treat the registered owner of each Trust Interest as the sole owner thereof. Upon the transfer of a Trust Interest on the books of the Trustees, the transferee shall, except as herein otherwise provided, be substituted for the prior registered owner and shall be a Beneficiary, having the rights and be subject to the obligations with respect to the Trust Interest of the original Beneficiary. Transferees who are not Depositors will not become Depositors as a result of the transfer. No party other than a Smith Family Member may be a Depositor or a Beneficiary. The Trustees may, in their discretion, from time to time cause the transfer books to be closed for such reasonable period of time as the Trustees may deem expedient.

2. Transfer of Trust Interests. A Beneficiary may at any time freely sell or otherwise transfer or dispose of any or all of the Trust Interests owned by the Beneficiary to any Smith Family Member. Except as set forth above, Trust Interests shall not be transferable. Transfer of the underlying Shares may occur, subject to Paragraph 3 below.

3. Transfer of Shares; Withdrawals. Whenever any Depositor or Beneficiary, or his estate, personal representative, executor, or other representative, desires to withdraw from the Trust, or sell or otherwise transfer or dispose of any and/or all of the Shares represented by Trust Interests, or whenever a Beneficiary ceases to be eligible to be a party to this Agreement by virtue of a change in the status of the Beneficiary, or the Beneficiary or the Depositor ceases to be eligible to participate in the Voting Trust because the Beneficiary or the Depositor is not an Eligible Transferee, the following procedures shall be observed:

(a) The Trustees shall give notice to the Beneficiary or the Depositor of the termination of that party’s status as an eligible party hereto, or in the event of withdrawal or proposed transfer, the Beneficiary shall give written notice of the intended withdrawal and/or transfer to the Secretary, which notice shall disclose the number of Shares represented by the Trust Interests to be withdrawn and/or transferred, the date of the proposed withdrawal and/or transfer (which shall not be less than thirty days after such notice), and such other pertinent information as the Trustees may request.

(b) Shares the subject of a notice referred to in subparagraph (a) above (a “Notice of Withdrawal”) which constitute Class A Common Stock shall automatically be exchanged for Shares of Common Stock held by the Trust on a one-for-one share basis, to the extent available in the Trust from the accounts of Eligible Transferees. Said exchange shall be deemed effective immediately prior to the time of the proposed withdrawal or transfer. As a result of such an exchange, the remaining Trust Interest accounts of the Beneficiaries who are Permitted Transferees (as defined in the AOS Certificate) shall be adjusted on a pro rata basis based on each Beneficiary’s Trust Interests attributable to Common Stock or pursuant to such other method as the Trustees deem fair and equitable.

(c) A Notice of Withdrawal shall, by virtue of this Agreement, constitute an offer to sell the Shares represented by the Trust Interests specified therein to the Trust, in accordance with the provisions hereof, at a price per share equal to the average closing sales price per share of Common Stock of AOS as traded on the New York Stock Exchange (or such other national securities exchange or system, if applicable) for the ten (10) trading days immediately prior to the date on which the Shares are proposed to be withdrawn or transferred. In the event part or all of said Shares comprise Class A Stock after giving effect to subparagraph (b) above, the price per share for Class A Stock shall not differ from that of Common Stock.

G-5

(d) The Secretary shall review the Certificates of Intent on file with the Trustees. If sufficient interest has been expressed, the Trust, at the sole discretion of the Trustees, may do any (or none) of the following: (i) purchase Common Stock from other sources for the purpose of exchanging shares of the Common Stock for shares of Class A Stock pursuant to subparagraph (b) above; (ii) purchase for cash some or all of the Shares that are Class A Shares; or (iii) subject to the prior written consent of the Beneficiary, purchase for cash some or all of the Shares that are Common Stock. Shares purchased hereunder shall be allocated to the accounts of the purchasing Depositors on a pro rata basis.

(e) The Trustees may, in their discretion, permit the “Withdrawing Beneficiary” to withdraw his or her offer of sale at any time prior to the time of transfer or withdrawal.

(f) If the Trust does not purchase any or all of the Shares represented by the Trust Interests so offered, the Withdrawing Beneficiary may withdraw the Shares that were not purchased and the Trustees shall cause AOS to promptly deliver to said party certificates or other evidence of ownership as may be provided by AOS for said Shares.

VI.

ELECTION AND REMOVAL OF TRUSTEES

1. Term of Office. Each Trustee shall hold office until he resigns, dies, becomes incapacitated, or refuses to act or is removed as hereinafter provided. Any Trustee may resign at any time by mailing or delivering a written notice of his resignation to each of the remaining Trustees. A person designated to act as an additional or successor Trustee shall become a Trustee upon mailing or delivering to each of the then acting Trustees an acknowledgement that he accepts the trust herein set forth. The Trustees shall promptly notify the Beneficiaries upon the addition or succession of a Trustee.

2. Additional or Successor Trustees. In addition to the original Trustees hereunder, one or more additional or successor Trustees may be appointed at any time by the unanimous action of the qualified and acting Trustees hereunder. Each Trustee shall have the power, by written instrument delivered to the Secretary, or by his last Will and Testament, to nominate and appoint a successor as Trustee. In case any Trustee shall die, resign, become incapacitated or be removed without having nominated a successor, such successor shall be appointed by unanimous action of the remaining or surviving Trustee or Trustees. Any additional or successor Trustee must be a Permitted Transferee or a trustee of a trust which is both a Beneficiary hereunder and a Permitted Transferee.

3. Removal. Any Trustee may be removed at any time, with or without cause, by the affirmative action of Beneficiaries possessing Trust Interests representing at least two-thirds (2/3) of the voting power of all Shares then held by the Trustees hereunder.

VII.

AMENDMENT AND TERMINATION

1. Amendment. This Trust may be amended from time to time by unanimous agreement of the Trustees; provided, however, that if in the judgment of the Trustees, whose determination shall be conclusive and binding upon all of the parties, an amendment adopted by the Trustees effects a substantial change in the rights of Beneficiaries, such amendment shall not be effective unless approved in writing by the Beneficiaries having Trust Interests representing at least a majority of the Shares then held hereunder. Written notice of all amendments shall be given promptly to all Beneficiaries. Any Beneficiary whose rights hereunder are determined by the Trustees to be subject to a materially adverse change effected by any such amendment may withdraw the Shares represented by Trust Interests held by him, subject to the procedures set forth in Paragraph V.3 above, but only if written notice is given to the Secretary within fifteen (15) days following mailing of notice of such amendment by the Secretary. Approval of such proposed amendment shall constitute a waiver of the right to withdraw the Shares.

2. Term and Termination. This Agreement may be terminated at any time by the affirmative vote of Beneficiaries having Trust Interests representing in the aggregate at least seventy-five percent (75%) of the

G-6

voting power of the Shares then held hereunder. Unless so terminated, this Agreement shall continue in full force and effect for a period of thirty (30) years and such additional thirty (30) year renewal periods as follow; provided, however, that if the permissible duration of this Agreement shall be limited to any lesser period by operation of law, this Agreement shall terminate upon the expiration of such lesser permitted period of duration.

3. Withdrawal. Except as otherwise provided herein, a Beneficiary may withdraw a part or all of the Shares represented by Trust Interests owned by him only upon unanimous consent of the Trustees and in accordance with the procedures set forth in Part V hereof. The Trustees shall provide unanimous consent unless good cause exists to withhold it. Any Beneficiary may also be required at any time, by the Trustees, to withdraw the Shares represented by the Trust Interests owned by him, with such withdrawal to proceed in accordance with the procedures set forth in Part V.

4. Terminal Distributions. Whenever this Agreement shall terminate, the rights of all parties hereunder shall terminate, except the rights of the Beneficiaries to the Shares held in their respective accounts and their distributive share of the proceeds of the Trust as hereinafter in this Paragraph 4 provided. In case of termination of this Agreement, every Beneficiary, and in case of termination of this Agreement as to a withdrawing Beneficiary only, such Beneficiary, upon the payment of his pro rata share of the costs, expenses, disbursements and outlays of the Trustees shall be entitled to his pro rata portion of all property, securities, and cash held by or for the Trustees hereunder. Beneficiaries, by the acceptance of their respective pro rata portion or a part of any property, securities, or cash distributed by the Trustees, shall thereby be deemed to have released and discharged the Trustees, their agents and attorneys, from all liability and accountability under this Agreement of every kind, character, and description whatsoever.

VIII.

NOTICES

1. Meetings. Whenever a meeting of the Beneficiaries as a class shall be requested in writing by the Trustees or by Beneficiaries who will be entitled to cast at least ten percent (10%) of all the votes which would be entitled to be cast at such meeting, the Secretary shall call such meeting within thirty (30) days and shall promptly give notice to all persons entitled to be present at such meeting, specifying the time and place of holding the meeting and the business proposed to be transacted. The Secretary shall likewise give notice of all meetings of Trustees to each Trustee, specifying the time and place of holding the meeting and the business proposed to be transacted. Such notices shall be given not less than ten (10) days before the time of holding the meeting but notice may be waived in writing or by presence at the meeting.

2. Method. Any and all notices herein provided shall be in writing and personally delivered or shall be given by mailing such notice by registered mail, return receipt requested, to the address of the person or corporation to whom such notice is given as shown upon the records of the Trustees, and, in the event that notice is given to the Secretary, it shall be given to him at his address as specified in the most recent notice given by him to the Beneficiaries. In the case of any requirement in this Agreement that such notice be for any number of days, such time shall run from the personal delivery thereof or from the mailing of such notice, exclusive of the day of mailing, and the affidavit of the person giving such notice as to the delivery or mailing thereof in case such person is a Trustee or the Secretary shall be conclusive.

IX.

MISCELLANEOUS

1. Voting. Unless otherwise expressly provided herein, whenever any action is to be taken by any class of persons hereunder (i.e., the Trustees or the Beneficiaries), such class of persons may act either (a) by a vote in person or by a proxy at a meeting of such class of persons, or (b) by an instrument or concurrent instruments in writing, signed by the number or proportion in interest (as required herein) of such class of persons without a formal meeting; provided, however, that a Trustee may vote as such in person or by written instrument, but not by proxy.

3. Liability. No Trustee shall be liable or responsible for any act or omission hereunder, including acts or omissions of any agents, except for his own individual personal malfeasance, nor shall any Trustee, whether original or successor or substitute, at any time be required to give or file any bond or other security in order to qualify or continue as a Trustee hereunder, unless the giving of such bond shall be directed by the Trustees, in which event the cost of such bond shall be considered and treated as an expense of the Trust. No person (including Beneficiaries) incurring any loss resulting from liability for breach of any fiduciary duty with respect to this Trust shall be entitled to indemnification out of the assets of the Trust.

4. Severability. If any provision of this Agreement shall under any circumstances be deemed invalid or inoperative to any extent, it is agreed and understood that such invalidity shall not invalidate the whole Agreement, but the Agreement shall be construed as not containing any provision or provisions so deemed invalid and inoperative, and the rights and obligations of the parties shall be construed and enforced accordingly.

5. Gender. Masculine pronouns used in this Agreement are intended to refer to both male and female persons and to entities.

6. Experts. The Trustees may employ legal counsel, accountants and other consultants to assist them in the exercise of their authority, and may rely upon the advice so obtained.

9. Securities Laws. It is acknowledged that requirements and restrictions of various laws, including federal and state securities laws, may impose limitations upon the Trustees in the performance of their duties and obligations hereunder on behalf of the Trust, including limitations as to the timing and volume of Trust purchases or sales of AOS securities.

A.O. Smith Corporation

11270 West Park Place

Members of the Special Committee of the Board of Directors

and Members of the Board of Directors:

We understand that Smith Investment Company (the “Company”), A.O. Smith Corporation (the “Parent”) and SICO Acquisition, LLC (“MergerCo”), a wholly owned subsidiary of Parent, propose to enter into an Agreement and Plan of Merger, dated as of December 9, 2008 (the “Merger Agreement”), which provides, among other things, for (i) the spin-off by the Company to its shareholders of the operations of its subsidiaries Berlin Industries, Inc. and Central States Distribution Service, Inc. (the “Spin-Off”); and (ii) the subsequent merger (the “Merger”) of the Company with and into MergerCo. All capitalized terms used and not otherwise defined herein have the meanings ascribed to them in the Merger Agreement. Pursuant to the Merger, the Company will become a wholly owned subsidiary of the Parent, and each outstanding share of common stock, par value $0.10 per share, of the Company (the “Company Common Stock”), other than shares held in treasury, or owned by the Company, or any wholly owned subsidiary of the Company or by the Parent, MergerCo or any other wholly owned subsidiary of the Parent, or as to which dissenters’ rights have been perfected, will be converted into the right to receive (i) the number of shares of Class A common stock, par value $5.00 per share, of the Parent (the “Parent Class A Common Stock”) equal to the Class A Exchange Ratio, (ii) the number of shares of common stock, par value $1.00 per share, of the Parent (the “Parent Common Stock”) equal to the Closing Common Exchange Ratio and (iii) the number of Escrow Shares equal to the Per Share Escrow Release Number, if any, upon release thereof pursuant to the Escrow Agreement (the number of shares referred to in clauses (i), (ii) and (iii), collectively, the “Exchange Ratio”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the Parent.

For purposes of the opinion set forth herein, we have:

reviewed certain publicly available financial statements and other business and financial information of the Parent and the Company, respectively;

reviewed certain internal financial statements and other financial and operating data concerning the Parent and the Company, respectively;

discussed the past and current operations and financial condition and the prospects of the Parent with senior executives of the Parent;

discussed the past and current operations and financial condition and the prospects of the Company with senior executives of the Company;

reviewed the reported prices and trading activity for the Parent Common Stock, Parent Class A Common Stock and the Company Common Stock;

compared the financial performance of the Parent and the prices and trading activity of the Parent Common Stock with that of certain other publicly-traded companies comparable with the Parent and its securities;

H-1

reviewed the financial terms, to the extent publicly available, of certain comparable merger transactions;

participated in certain discussions and negotiations among representatives of the Parent and the Company and their financial and legal advisors;

reviewed the Merger Agreement and certain related documents; and

10)

performed such other analyses and considered such other factors as we have deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to us by the Parent and the Company, and formed a substantial basis for this opinion. We have assumed that the Spin-Off and the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the Merger will be treated as a tax-free reorganization and/or exchange, each pursuant to the Internal Revenue Code of 1986, as amended. For the avoidance of doubt, and without limiting the foregoing, we have assumed that the Parent will not assume any tax liability in respect of the Spin-Off. Morgan Stanley has assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed Spin-Off and Merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed Spin-Off and Merger. We are not legal, tax or regulatory advisors. We are financial advisors only and have relied upon, without independent verification, the assessment of the Parent and the Company and their legal, tax or regulatory advisors with respect to such matters. We have not made any independent valuation or appraisal of the assets or liabilities of the Parent or Company, nor have we been furnished with any such appraisals. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

We have acted as financial advisor to the Special Committee of the Board of Directors of the Parent in connection with this transaction and will receive a fee for our services, a substantial portion of which is contingent upon the rendering of this financial opinion and another portion of which is contingent upon the closing of the Merger.

Please note that Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Our securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of the Parent, the Company, or any other company, or any currency or commodity, that may be involved in this transaction, or any related derivative instrument.

This opinion has been approved by a committee of Morgan Stanley investment banking and other professionals in accordance with our customary practice. This opinion is for the information of the Special Committee of the Board of Directors and the Board of Directors of the Parent and may not be used for any other purpose without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing the Parent is required to make with the Securities and Exchange Commission in connection with this transaction if such inclusion is required by applicable law. In addition, this opinion does not in any manner address the prices at which the Parent’s Common Stock will trade following consummation of the Merger and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of the Parent should vote at the shareholders’ meeting to be held in connection with the Merger.

H-2

Based on and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the Parent.


Very truly yours, MORGAN STANLEY & CO. INCORPORATED

CONFIDENTIAL

Special Committee of the Board of Directors

Smith Investment Company

11270 West Park Place

Milwaukee, WI 53224

Dear Members of the Special Committee:

Smith Investment Company (“SICO” or the “Company”) has engaged Duff & Phelps Securities, LLC to provide independent financial advisory services to the Special Committee (the “Special Committee”) of the Board of Directors (the “Board of Directors”) of the Company and as part of the engagement, has requested Duff & Phelps, LLC (“Duff & Phelps”) to provide an opinion (the “Opinion”) to the Special Committee as of the date hereof as to the fairness, from a financial point of view, to the shareholders of the Company (other than the Smith Family Members (as defined in the Agreement) and their affiliates (the “Smith Family Members”)) of the consideration to be received by such holders in the contemplated transaction described below (the “Proposed Transaction”).

Description of the Proposed Transaction

The Proposed Transaction is comprised of a merger of the Company with and into a newly formed limited liability company and wholly owned subsidiary of A. O. Smith Corporation (“AOS”) in exchange for newly issued shares of AOS Class A Common Stock and AOS Common Stock, on the terms and subject to the conditions set forth in a draft Agreement and Plan of Merger among AOS, a newly formed wholly owned subsidiary of AOS, SICO, and Smith Investment Company LLC (the “Agreement”). Pursuant to the Agreement, each share of Common Stock of SICO (other than Dissenting Shares) shall be converted into the right to receive (i) the number of shares of AOS Class A Common Stock equal to 0.985 multiplied by the number of shares of AOS Class A Common Stock held by SICO divided by the number of outstanding shares of SICO Common Stock, (ii) the number of shares of AOS Common Stock equal to (A)(1) 0.985 multiplied by the number of shares of AOS Common Stock held by SICO minus (2) the shares to be placed into escrow, divided by (B) the number of outstanding shares of SICO Common Stock, and (iii) its pro rata share of the shares placed in escrow, upon release from escrow. Prior to completion of the Proposed Transaction, SICO will transfer substantially all of its assets (other than the Class A Common Stock and Common Stock of AOS held by it) and liabilities to Smith Investment Company LLC, and all of the equity interests in Smith Investment Company LLC will be distributed to the shareholders of SICO (such transfer and distribution, the “Spin-off”). Duff & Phelps has not been requested to, and does not in this Opinion, address or otherwise provide any opinion with respect to the Spin-off. The Opinion provided in this letter is only given with respect to the Proposed Transaction.

Scope of Analysis

In connection with this Opinion, Duff & Phelps has made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Duff & Phelps also took into account its assessment of general economic, market and financial conditions, as well as its experience in securities and business valuation, in general, and with respect to similar transactions, in particular. Duff & Phelps’ procedures, investigations, and financial analysis with respect to the preparation of our Opinion included, but were not limited to, the items summarized below:

1.	Discussed the Proposed Transaction with the Special Committee and its representatives and the Company and its management and representatives;

I-1

Special Committee of the Board of Directors

Smith Investment Company

Page 2 of 4

2.	Reviewed certain publicly available business and financial information of the Company and AOS, respectively;

3.	Reviewed certain internally prepared financial and operating data concerning the Company, which the Company has identified as being the most current financial statements available;

Reviewed drafts of the following documents related to the Proposed Transaction: the Agreement and, in each case as defined in the Agreement, a form of each of the Company Support Agreement, the Parent Support Agreement, the Parent Charter, the Parent Charter Amendment, the Escrow Agreement, the Stockholder Agreement and the Voting Trust Agreement;

5.	Reviewed the historical trading prices and trading volumes of the Company Common Stock, AOS Class A Common Stock and AOS Common Stock; and

6.	Conducted such other analyses and considered such other factors as we deemed appropriate.

Assumptions, Qualifications and Limiting Conditions

In performing its analyses and rendering this Opinion with respect to the Proposed Transaction, Duff & Phelps, with your consent:

1.	Assumed that the Proposed Transaction will be treated as a tax-free reorganization for United States Federal income tax purposes;

2.	Did not address the impact of the Proposed Transaction on any particular shareholder other than in such shareholder’s capacity as a shareholder;

Relied upon the accuracy, completeness, and fair presentation of all information, data, advice, opinions and representations obtained from public sources or provided to it from private sources, including the Company and its management and representatives and the Special Committee and its representatives, and did not independently verify such information;

4.	Assumed that the final versions of all documents reviewed by Duff & Phelps in draft form conform in all material respects to the drafts reviewed;

5.	Assumed that information supplied to Duff & Phelps and representations and warranties made in the Agreement are accurate in all material respects;

6.	Assumed that all of the conditions required to implement the Proposed Transaction will be satisfied and that the Proposed Transaction will be completed in accordance with the Agreement without any amendments thereto or any waivers of any terms or conditions thereof;

7.	Relied upon the fact that the Special Committee and the Company have engaged such tax, accounting and legal advisors as they have deemed necessary, and is giving no opinion herein with respect to any tax, accounting or legal matters;

Assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Proposed Transaction will be obtained without any adverse effect (including any delay, limitation, condition or restriction) on the Company, AOS or the contemplated benefits expected to be derived in the Proposed Transaction; and

Assumed that each member or descendant of the Smith family and each trust for the benefit of members or descendants of the Smith family that is, was or will be required by applicable law or regulation to be a signatory to the Schedule 13D (as defined in the Agreement) has signed or will sign such Schedule 13D, as required.

10.	Has not taken into account the effect, positive or negative, that any tax attribute of the Company being assumed (including by operation of law) by or transferred to AOS in the Proposed Transaction would have on the Proposed Transaction.

11.	Assumed, based on the direction of the Special Committee, that any alternative to the Proposed Transaction involving a sale of the Company to a third party or a recapitalization of AOS to eliminate its dual class equity structure would be futile and therefore not available.

In our analysis and in connection with the preparation of this Opinion, Duff & Phelps has made numerous assumptions with respect to industry performance, general business, market and economic conditions and other matters, many of which are beyond the control of any party involved in the Proposed Transaction. To the extent that any of the foregoing assumptions insofar as they affect the Proposed Transaction or any of the facts on which this Opinion is based prove to be untrue in any material respect, this Opinion cannot and should not be relied upon.

Duff & Phelps did not make any independent evaluation of the Company’s, Smith Investment Company LLC’s or AOS’s solvency or any appraisal or physical inspection of any specific assets or liabilities (contingent or otherwise), nor have we been furnished with any such evaluations or appraisals. Duff & Phelps is not a legal, tax, accounting or regulatory advisor and has relied upon, without independent verification, the assessment of the Company and its legal, tax, accounting and regulatory advisors with respect to such matters, and Duff & Phelps has made no assessment as to the impact or timing implications, if any, of any ongoing legal or regulatory investigations. Duff & Phelps has undertaken no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which the Company is or may be a party or is or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which the Company is or may be a party or is or may be subject and, at your direction and with your consent, this Opinion makes no assumption concerning, and therefore does not consider, the potential effects of such litigation, claims or investigations or possible assertions of claims, outcomes or damages arising out of any such matters. This Opinion should not be construed as a valuation opinion, credit rating, solvency opinion, analysis of the Company’s, Smith Investment Company LLC’s or AOS’s credit worthiness, tax advice, or accounting advice. Duff & Phelps has not been requested to, and did not, (a) initiate any discussions with, or solicit any indications of interest from, third parties with respect to the Proposed Transaction, the assets, businesses or operations of the Company, or any alternatives to the Proposed Transaction or (b) negotiate the terms of the Proposed Transaction, and therefore, Duff & Phelps has assumed that such terms are the most beneficial terms, from the Company’s perspective, that could, under the circumstances, be negotiated among the parties to the Agreement and the Proposed Transaction. In addition, Duff & Phelps is not expressing any opinion as to the market price or value of the Company Common Stock or the AOS Class A Common Stock or AOS Common Stock following the public announcement of the Proposed Transaction. Duff & Phelps has not made, and assumes no responsibility to make, any representation, or render any opinion, as to any legal matter.

In rendering this Opinion, Duff & Phelps is not expressing any opinion with respect to the amount or nature of any compensation to any of the Company’s officers, directors, or employees, or any class of such persons, relative to the consideration to be received by the shareholders of the Company (other than the Smith Family Members) in the Proposed Transaction, or with respect to the fairness of any such compensation.

The Proposed Transaction is not comparable to other transactions that Duff & Phelps has reviewed and, in rendering this Opinion, Duff & Phelps has relied solely on an analysis designed specifically for the Proposed Transaction. This Opinion (a) does not address the merits of the underlying business decision to enter into the

I-3

Special Committee of the Board of Directors

Smith Investment Company

December 9, 2008

Page 4 of 4

Proposed Transaction versus any alternative strategy or transaction; (b) is not a recommendation as to how the Special Committee, Board of Directors or any shareholder should vote or act with respect to any matters relating to the Proposed Transaction, or whether to proceed with the Proposed Transaction or any related transaction, and (c) does not indicate that the consideration received is the best possibly attainable under any circumstances. The decision as to whether to proceed with the Proposed Transaction or any related transaction may depend on an assessment of factors unrelated to the financial analysis on which this Opinion is based. This letter should not be construed as creating any fiduciary duty on the part of Duff & Phelps to any party.

Duff & Phelps has prepared this Opinion effective as of the date hereof, and this Opinion speaks as of the date hereof and not any future date. This Opinion is necessarily based upon market, economic, financial and other conditions as they exist and can be evaluated as of the date hereof, and Duff & Phelps disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting this Opinion which may come or be brought to the attention of Duff & Phelps after the date hereof.

This Opinion is for the information of the Special Committee and may be relied upon by the Board of Directors, but is not intended to, and it does not, confer any rights or remedies upon any other person, and is not intended to be used, and may not be used, for any other purpose without our prior written consent, except to the extent specifically permitted in this paragraph. This Opinion may be included in its entirety in any proxy statement distributed to shareholders of the Company in connection with the Proposed Transaction or other document required by law or regulation to be filed with the Securities and Exchange Commission, and you may summarize or otherwise reference the existence of this Opinion in such documents, provided that any such summary or reference language shall be in a form reasonably acceptable to Duff & Phelps and its counsel. Except as described above, without our prior consent, this Opinion may not be quoted from or referred to, in whole or in part, in any written document or used for any other purpose.

Duff & Phelps has acted as financial advisor to the Special Committee, and will receive a fee for its services. No portion of Duff & Phelps’ fee is contingent upon either the conclusion expressed in the Opinion or whether the Proposed Transaction is successfully consummated. Pursuant to the terms of the engagement letter between the Company and Duff & Phelps, a portion of Duff & Phelps’ fee is payable upon Duff & Phelps’ stating to the Special Committee that it is prepared to deliver its Opinion. Other than this engagement, during the two years preceding the date of this Opinion, Duff & Phelps has not had any material relationship with any party to the Proposed Transaction for which compensation has been received or is intended to be received. This Opinion has been approved by the internal opinion committee of Duff & Phelps.

Conclusion

Based upon and subject to the foregoing, Duff & Phelps is of the opinion that as of the date hereof the consideration to be received by the shareholders of the Company (other than the Smith Family Members) in the Proposed Transaction is fair, from a financial point of view, to such holders.

Respectfully submitted,

1. Except as otherwise provided in subsection 2, and unless otherwise provided in the articles or bylaws, any member of any constituent domestic nonprofit corporation who voted against the merger may, without prior notice, but within 30 days after the effective date of the merger, resign from membership and is thereby excused from all contractual obligations to the constituent or surviving corporations which did not occur before his resignation and is thereby entitled to those rights, if any, which would have existed if there had been no merger and the membership had been terminated or the member had been expelled.

2. Unless otherwise provided in its articles of incorporation or bylaws, no member of a domestic nonprofit corporation, including, but not limited to, a cooperative corporation, which supplies services described in chapter 704 of NRS to its members only, and no person who is a member of a domestic nonprofit corporation as a condition of or by reason of the ownership of an interest in real property, may resign and dissent pursuant to subsection 1.

(1) If approval by the stockholders is required for the conversion or merger by NRS 92A.120 to 92A.160, inclusive, or the articles of incorporation, regardless of whether the stockholder is entitled to vote on the conversion or plan of merger; or

(2) If the domestic corporation is a subsidiary and is merged with its parent pursuant to NRS 92A.180.

(b) Consummation of a plan of exchange to which the domestic corporation is a constituent entity as the corporation whose subject owner’s interests will be acquired, if his shares are to be acquired in the plan of exchange.

(c) Any corporate action taken pursuant to a vote of the stockholders to the extent that the articles of incorporation, bylaws or a resolution of the board of directors provides that voting or nonvoting stockholders are entitled to dissent and obtain payment for their shares.

(d) Any corporate action not described in paragraph (a), (b) or (c) that will result in the stockholder receiving money or scrip instead of fractional shares except where the stockholder would not be entitled to receive such payment pursuant to NRS 78.205, 78.2055 or 78.207.

2. A stockholder who is entitled to dissent and obtain payment pursuant to NRS 92A.300 to 92A.500, inclusive, may not challenge the corporate action creating his entitlement unless the action is unlawful or fraudulent with respect to him or the domestic corporation.

3. From and after the effective date of any corporate action described in subsection 1, no stockholder who has exercised his right to dissent pursuant to NRS 92A.300 to 92A.500, inclusive, is entitled to vote his shares for any purpose or to receive payment of dividends or any other distributions on shares.

J-2

vote at the meeting at which the plan of merger or exchange is to be acted on, were either listed on a national securities exchange, included in the national market system by the National Association of Securities Dealers, Inc., or held by at least 2,000 stockholders of record, unless:

(a) The articles of incorporation of the corporation issuing the shares provide otherwise; or

(b) The holders of the class or series are required under the plan of merger or exchange to accept for the shares anything except:

(II) Any other entity which, at the effective date of the plan of merger or exchange, were either listed on a national securities exchange, included in the national market system by the National Association of Securities Dealers, Inc., or held of record by a least 2,000 holders of owner’s interests of record; or

(2) A combination of cash and owner’s interests of the kind described in sub-subparagraphs (I) and (II) of subparagraph (1) of paragraph (b).

2. There is no right of dissent for any holders of stock of the surviving domestic corporation if the plan of merger does not require action of the stockholders of the surviving domestic corporation under NRS 92A.130.

NRS 92A.400 Limitations on right of dissent: Assertion as to portions only to shares registered to stockholder; assertion by beneficial stockholder.

A stockholder of record may assert dissenter’s rights as to fewer than all of the shares registered in his name only if he dissents with respect to all shares beneficially owned by any one person and notifies the subject corporation in writing of the name and address of each person on whose behalf he asserts dissenter’s rights. The rights of a partial dissenter under this subsection are determined as if the shares as to which he dissents and his other shares were registered in the names of different stockholders.

2. A beneficial stockholder may assert dissenter’s rights as to shares held on his behalf only if:

(a) He submits to the subject corporation the written consent of the stockholder of record to the dissent not later than the time the beneficial stockholder asserts dissenter’s rights; and

2. If the corporate action creating dissenters’ rights is taken by written consent of the stockholders or without a vote of the stockholders, the domestic corporation shall notify in writing all stockholders entitled to assert dissenters’ rights that the action was taken and send them the dissenter’s notice described in NRS 92A.430.

2. The stockholder who demands payment and deposits his certificates, if any, before the proposed corporate action is taken retains all other rights of a stockholder until those rights are cancelled or modified by the taking of the proposed corporate action.

2. The payment must be accompanied by:

(a) The subject corporation’s balance sheet as of the end of a fiscal year ending not more than 16 months before the date of payment, a statement of income for that year, a statement of changes in the stockholders’ equity for that year and the latest available interim financial statements, if any;

(d) A statement of the dissenter’s rights to demand payment under NRS 92A.480; and

2. To the extent the subject corporation elects to withhold payment, after taking the proposed action, it shall estimate the fair value of the shares, plus accrued interest, and shall offer to pay this amount to each dissenter who agrees to accept it in full satisfaction of his demand. The subject corporation shall send with its offer a statement of its estimate of the fair value of the shares, an explanation of how the interest was calculated, and a statement of the dissenters’ right to demand payment pursuant to NRS 92A.480.

2. A dissenter waives his right to demand payment pursuant to this section unless he notifies the subject corporation of his demand in writing within 30 days after the subject corporation made or offered payment for his shares.

J-5

NRS 92A.490 Legal proceeding to determine fair value: Duties of subject corporation; powers of court; rights of dissenter.

1. If a demand for payment remains unsettled, the subject corporation shall commence a proceeding within 60 days after receiving the demand and petition the court to determine the fair value of the shares and accrued interest. If the subject corporation does not commence the proceeding within the 60-day period, it shall pay each dissenter whose demand remains unsettled the amount demanded.

2. A subject corporation shall commence the proceeding in the district court of the county where its principal office is located. If the principal office of the subject corporation is not located in the State, it shall commence the proceeding in the county where the principal office of the domestic corporation merged with or whose shares were acquired by the foreign entity was located. If the principal office of the subject corporation and the domestic corporation merged with or whose shares were acquired is not located in this State, the subject corporation shall commence the proceeding in the district court in Carson City.

3. The subject corporation shall make all dissenters, whether or not residents of Nevada, whose demands remain unsettled, parties to the proceeding as in an action against their shares. All parties must be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law.

4. The jurisdiction of the court in which the proceeding is commenced under subsection 2 is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend a decision on the question of fair value.

5. Each dissenter who is made a party to the proceeding is entitled to a judgment:

(a) For the amount, if any, by which the court finds the fair value of his shares, plus interest, exceeds the amount paid by the subject corporation; or

(b) For the fair value, plus accrued interest, of his after-acquired shares for which the subject corporation elected to withhold payment pursuant to NRS 92A.470.

NRS 92A.500 Legal proceeding to determine fair value: Assessment of costs and fees.

1. The court in a proceeding to determine fair value shall determine all of the costs of the proceeding, including the reasonable compensation and expenses of any appraisers appointed by the court. The court shall assess the costs against the subject corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters acted arbitrarily, vexatiously or not in good faith in demanding payment.

2. The court may also assess the fees and expenses of the counsel and experts for the respective parties, in amounts the court finds equitable:

(a) Against the subject corporation and in favor of all dissenters if the court finds the subject corporation did not substantially comply with the requirements of NRS 92A.300 to 92A.500, inclusive; or

(b) Against either the subject corporation or a dissenter in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in good faith with respect to the rights provided by NRS 92A.300 to 92A.500, inclusive.

3. If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated, and that the fees for those services should not be assessed against the subject corporation, the court may award to those counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited.

J-6

4. In a proceeding commenced pursuant to NRS 92A.460, the court may assess the costs against the subject corporation, except that the court may assess costs against all or some of the dissenters who are parties to the proceeding, in amounts the court finds equitable, to the extent the court finds that such parties did not act in good faith in instituting the proceeding.

5. This section does not preclude any party in a proceeding commenced pursuant to NRS 92A.460 or 92A.490 from applying the provisions of N.R.C.P. 68 or NRS 17.115.

J-7

PART II—INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20.

Indemnification of Directors and Officers.

Under the provisions of Section 145 of the DGCL, A. O. Smith is required to indemnify any present or former officer or director against expenses arising out of legal proceedings in which the director or officer becomes involved by reason of being a director or officer if the director or officer is successful in the defense of such proceedings. Section 145 also provides that A. O. Smith may indemnify a director or officer in connection with a proceeding in which he is not successful in defending if it is determined that he acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of A. O. Smith or, in the case of a criminal action, if it is determined that he had no reasonable cause to believe his conduct was unlawful. Liabilities for which a director or officer may be indemnified include amounts paid in satisfaction of settlements, judgments, fines and other expenses (including attorneys’ fees incurred in connection with such proceedings). In a stockholder derivative action, no indemnification may be paid in respect of any claim, issue or matter as to which the director or officer has been adjudged to be liable to A. O. Smith (except for expenses allowed by a court).

Under the provisions of Article VII of A. O. Smith’s bylaws and individual indemnity agreements between A. O. Smith and its directors and certain of its officers, A. O. Smith is required to indemnify officers or directors to a greater extent than under the current provisions of Section 145 of the DGCL. Except with respect to stockholder derivative actions, the bylaw provisions and the indemnity agreements generally state that the director or officer will be indemnified against expenses, amounts paid in settlement and judgments, fines, penalties and/or other amounts incurred with respect to any threatened, pending or completed proceeding (including, without limitation, proceedings brought under and/or predicated upon the Securities Act and/or the Exchange Act); provided that (a) such individual did not engage in criminal, fraudulent or intentional misconduct in the performance of his duties to A. O. Smith; (b) with respect to criminal actions, such individual had no reasonable cause to believe his conduct was unlawful; and (c) with respect to securities law actions, such individual acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of A. O. Smith and its stockholders.

The foregoing standards also apply with respect to the indemnification of expenses incurred in a stockholder derivative suit. However, in order for a director or officer to be indemnified for settlement amounts or judgments incurred in a derivative suit, it also must be determined that (a) such individual has not breached his duty of loyalty to A. O. Smith or its stockholders; (b) has not committed acts or omissions in bad faith or which involve intentional misconduct or a knowing violation of the law; (c) has not engaged in any willful or negligent conduct in paying dividends or repurchasing stock of A. O. Smith out of other than lawfully available funds; and (d) has not derived an improper personal benefit from the subject transaction.

The registrant has purchased insurance on behalf of its directors and officers against certain liabilities that may be asserted against, or incurred by, such persons in their capacities as directors or officers of the registrant or its subsidiaries, or that may arise out of their status as directors or officers of the registrant or its subsidiaries, including liabilities under the federal and state securities laws.

The foregoing statements are subject to the detailed provisions of Section 145 of the DGCL, the full text of the current certificate of incorporation and bylaws of A. O. Smith and the full text of the A. O. Smith Amended Charter that will be in effect upon completion of the transactions contemplated by the Merger Agreement. Copies of the current certificate of incorporation and bylaws of A. O. Smith and form of A. O. Smith Amended Charter that will be in effect upon completion of the transactions contemplated by the Merger Agreement are filed as exhibits to this registration statement.

Undertakings

(a) The undersigned registrant hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(1) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(2) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the

II-2

estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(3) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(b) The undersigned registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned registrant hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(d) The undersigned registrant hereby undertakes that, for purposes of determining liability under the Securities Act, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference in the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(e) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(f)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(g) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions hereof, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification

II-3

against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(h) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference in the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(i) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
