RISK FACTORS

Investing in our securities involves risk. Please see the risk factors set forth in Part I, Item 1A in Infinity’s Annual Report on Form 10-K for its most recent fiscal year, as updated by its quarterly reports on Form 10-Q and other filings it makes with the SEC, as incorporated by reference in this prospectus. Additional risk factors may be included in a prospectus supplement relating to a particular series or offering of securities. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. These risks could materially affect our business, results of operations or financial condition and cause the value of our securities to decline.

SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

This prospectus (including the information incorporated by reference) contains certain statements that may be deemed to be “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements anticipate results based on our estimates, assumptions and plans that are subject to uncertainty. The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements. All statements in this prospectus and any accompanying prospectus supplement not dealing with historical results or current facts are forward-looking and are based on estimates, assumptions and projections. Statements which include the words “believes”, “seeks”, “expects”, “may”, “should”, “intends”, “likely”, “targets”, “plans”, “anticipates”, “estimates” or the negative version of those words and similar statements of a future or forward-looking nature identify forward-looking statements. Examples of such forward-looking statements include statements relating to expectations concerning market conditions, premium, growth, earnings, investment performance, expected losses, rate changes and loss experience.

Factors that could cause actual results to differ from those in the forward-looking statements may accompany the statements themselves. In addition, generally applicable factors that could cause actual results or outcomes to differ from those expressed in the forward-looking statements are and will be discussed in Infinity’s reports on Forms 10-K, 10-Q and 8-K incorporated by reference in this prospectus.

All forward-looking statements address matters that involve risks and uncertainties. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in these statements. We do not undertake any obligation to publicly update or review any forward-looking statement.

INFINITY CAPITAL TRUST I

Infinity Capital Trust I is a statutory trust formed under Delaware law pursuant to a declaration of trust executed by Infinity, as sponsor, and the trustees (described below) and the filing of a certificate of trust with the Delaware Secretary of State. The trust’s declaration will be amended and restated as of the date the securities of the trust are initially issued. The amended declaration will be qualified as an indenture under the Trust Indenture Act of 1939.

The trust exists solely to:

•

issue its preferred securities and common securities representing undivided beneficial interests in the assets of the trust;

•

invest the proceeds from the issuance of those securities in Infinity’s junior subordinated debt securities; and

•

engage only in incidental activities.

The rights of the holders of the trust’s securities, including economic rights, rights to information and voting rights, will be set forth in the trust’s amended declaration of the trust, the Delaware Statutory Trust Act and the Trust Indenture Act.

Infinity will own, directly or indirectly, all of the common securities of the trust, which will have an aggregate liquidation amount equal to 3% of the total capital of the trust. The common securities will generally rank equally in right of payment with the preferred securities, and payments on both will be made pro rata. The securities to be issued by the trust may be designated as “capital securities,” or may be designated under any other name as set forth in the applicable prospectus supplement. However, upon an event of default under a trust’s amended declaration, the rights of the holders of the common securities to payment of distributions and payments upon liquidation, redemption and otherwise will be subordinated to the rights of the holders of the preferred securities. Infinity will pay all fees and expenses related to the trust and the offering of the trust’s securities.

Infinity, as holder of all of the common securities, will be entitled to appoint, remove or replace any of, or increase or reduce the number of, the trustees of the trust. The business and affairs of the trust will be conducted by the trustees, and the duties and obligations of the trustees will be governed by the amended declaration of the trust.

At least two of the trustees of the trust will be persons who are employees or officers of, or otherwise affiliated with, Infinity. These persons are sometimes referred to as “regular” trustees. One trustee of the trust will be a financial institution which will be unaffiliated with Infinity and will act as property trustee and as indenture trustee for purposes of the Trust Indenture Act under the terms of the applicable amended declaration and as may be further described in a prospectus supplement. The property trustee will hold title to the junior subordinated debt securities for the benefit of the holders of the trust’s securities. In addition, unless the property trustee maintains a principal place of business in the state of Delaware and otherwise meets the requirements of applicable law, one trustee of the trust will be a legal entity having a principal place of business in, or an individual resident of, the state of Delaware.

Unless otherwise indicated in a prospectus supplement, U.S. Bank National Association will be the property trustee and U.S. Bank Trust National Association will be the Delaware trustee. The address of the corporate trust office of U.S. Bank National Association is 425 Walnut Street, 6^th Floor, Cincinnati, Ohio 45202 and for U.S. Bank Trust National Association is 300 E. Delaware Avenue, 9^th Floor, Wilmington, Delaware 19801. The principal place of business of the trust will be c/o Infinity Property and Casualty Corporation, 3700 Colonnade Parkway, Birmingham, Alabama 35243, telephone number (205) 870-4000.

USE OF PROCEEDS

Unless otherwise indicated in an accompanying prospectus supplement, Infinity expects to use the net proceeds from the sale of any securities offered by it for general corporate purposes, which may include investment in insurance businesses and the repayment of outstanding debt and the debt of Infinity subsidiaries. Until the net proceeds are used for these purposes, Infinity may deposit them in interest-bearing accounts or invest them in short-term marketable securities. The specific allocations, if any, of the proceeds from the sale of any of the securities will be described in the prospectus supplement relating to the offering of the securities. The proceeds from any sale of preferred securities by the trust will be invested in Infinity debt securities.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth Infinity’s ratio of earnings to fixed charges for the periods indicated.


Six Months Ended June 30,	Year Ended December 31,
2010	2009	2008	2007	2006	2005
6.9	7.8	4.5	8.0	10.0	10.9

DESCRIPTION OF THE SECURITIES WE MAY OFFER

Infinity may issue, in one or more offerings, any combination of senior, subordinated or junior subordinated debt securities, common stock, preferred stock, warrants, depositary shares and units. The trust may issue in one or more offerings, trust preferred securities that will be unconditionally guaranteed by Infinity.

This prospectus contains a summary of the general terms of the various securities that we may offer. The prospectus supplement relating to any particular securities offered will describe the specific terms of the securities. The summary in this prospectus and in any prospectus supplement does not describe every aspect of the securities and is subject to and qualified in its entirety by reference to all applicable provisions of the documents relating to the securities offered. These documents are or will be filed as exhibits to or incorporated by reference in the registration statement.

In addition, the prospectus supplement will set forth the terms of the offering, the initial public offering price and net proceeds to Infinity or the trust. Where applicable, the prospectus supplement will also describe any material United States federal income tax considerations relating to the securities offered and indicate whether the securities offered are or will be listed on any securities exchange.

DESCRIPTION OF DEBT SECURITIES

Infinity may offer debt securities. The following description sets forth the general terms and provisions of the senior and subordinated debt securities (referred to collectively as the “debt securities”) that Infinity may offer. The applicable prospectus supplement will describe the specific terms of the debt securities offered by that prospectus supplement and any applicable tax considerations and any general terms outlined in this section that will not apply to those debt securities. We may also offer junior subordinated debentures described below under “—Description of Junior Subordinated Debentures.”

The prospectus supplement relating to any offering of preferred securities by a trust will contain the terms of the junior subordinated debt securities that would be issued by Infinity and sold to the trust using the proceeds from the sale of preferred securities.

Infinity’s senior debt securities are to be issued under a senior indenture between us and U.S. Bank National Association, as trustee, a form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Infinity’s subordinated debt securities are to be issued under a subordinated indenture between Infinity and U.S. Bank National Association, as trustee, a form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. The senior indenture and the subordinated indenture are sometimes referred to collectively as the “indentures” and each individually as an “indenture.”

- 7 -

Because the following summaries of the material terms and provisions of the indentures and the related debt securities are not complete, you should refer to the forms of the indentures and the debt securities for complete information regarding the terms and provisions of the indentures, including the definitions of some of the terms used below, and the debt securities. The senior indenture and the subordinated indenture are substantially identical, except for certain covenants of ours and provisions relating to subordination.

The prospectus supplement relating to any series of debt securities will describe the following specific financial, legal and other terms particular to such series of debt securities:

•

the designation of the debt securities of the series;

•

any limit upon the aggregate principal amount of the debt securities of the series and any limitation on our ability to increase the aggregate principal amount after the initial issuance of the debt securities of that series;

•

the date or dates on which the principal of the debt securities of the series is payable (which date or dates may be fixed or extendible);

•

the annual rate or rates (which may be fixed or variable) at which the debt securities of the series shall bear interest, if any, the date or dates from which such interest shall accrue, on which such interest shall be payable and on which a record shall be taken for the determination of holders to whom interest is payable and/or the method by which such rate or rates or date or dates shall be determined;

•

the place or places where principal of, premium, if any, and interest on debt securities of the series shall be payable;

•

our right, if any, to redeem debt securities of the series, in whole or in part, at our option and the period or periods within which, the price or prices at which and any terms and conditions upon which debt securities of the series may be so redeemed;

•

our obligation, if any, to redeem, purchase or repay debt securities of the series pursuant to any mandatory redemption or at the option of a holder and the price or prices at which and the period or periods within which and any of the terms and conditions upon which debt securities of the series shall be redeemed, purchased or repaid, in whole or in part;

•

if other than denominations of $1,000 and integral multiples of $1,000, the denominations in which debt securities of the series shall be issuable;

•

if other than the principal amount, the portion of the principal amount of debt securities of the series which shall be payable upon declaration of acceleration of the maturity;

•

whether the debt securities of the series or any portion thereof will be issuable as registered debt securities or unregistered debt securities (with or without coupons) (and if so, whether such debt securities will be issued in temporary or permanent global form), or any combination of the foregoing;

•

whether the debt securities of the series may be exchangeable for and/or convertible into our common stock or any other security;

•

whether and under what circumstances we will pay additional amounts on the debt securities of the series held by a person who is not a U.S. person in respect of any tax, assessment or governmental charge withheld or deducted and, if so, whether we will have the option to redeem such debt securities rather than pay such additional amounts;

- 8 -

•

provisions, if any, for the defeasance of the debt securities of the series (including provisions permitting defeasance of less than all debt securities of the series);

•

any other events of default or covenants with respect to the debt securities of the series; and

•

any other terms of the debt securities of the series (which terms shall not be inconsistent with the provisions of this Indenture), and any requirement to have our subsidiaries guarantee the debt securities.

Events Of Default

You will have special rights if an “event of default” occurs, with respect to any series of debt securities, and is not cured, as described later in this subsection. Under the indenture, the term “event of default” means any of the following:

•

we do not pay the principal on a debt security on its due date;

•

we do not pay interest on a debt security within 30 days of its due date;

•

we remain in breach of any covenant or warranty described in the indenture for 90 days after we receive a notice stating it is in breach, which notice must be sent by either the trustee or direct holders of at least 25% of the principal amount of outstanding debt securities;

•

we or one of our significant subsidiaries fails to pay an amount of indebtedness totaling more than $15,000,000 in principal amount, our obligation to repay is accelerated by its lenders, and this payment obligation remains accelerated for 30 days;

•

we or one of our significant subsidiaries fails to pay an amount of indebtedness totaling more than $15,000,000 in principal amount when due, and this payment obligation remains accelerated for 30 days;

•

we become subject to one or more final, non-appealable judgments, orders or decrees (not covered by insurance) requiring payments of more than $15,000,000 and such judgments, orders or decrees remain unsatisfied for 60 days during which a stay of enforcement has not been in effect; or

•

certain events of bankruptcy, insolvency or reorganization.

For purposes of the indentures, a “significant subsidiary” means a subsidiary meeting any of the conditions set forth in Rule 405 promulgated under the Securities Act.

Remedies if an Event of Default Occurs

If an event of default has occurred and has not been cured (if a cure period is provided for), the trustee or the direct holders of 25% in principal amount of the outstanding debt securities may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. This is called a “declaration of acceleration of maturity.”

Except in cases of default, whereby a trustee has some special duties, a trustee is not required to take any action under the indenture at the request of any direct holders unless the direct holders offer the trustee reasonable protection from costs, expenses and liability (called an “indemnity”). If reasonable

- 9 -

indemnity is provided, the direct holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority direct holders may also direct the trustee in performing any other action under the indenture.

In general, before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur:

•

you must give the trustee written notice that an event of default has occurred and remains uncured;

•

the direct holders of at least 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action in its own name as trustee because of the default, and must offer reasonable indemnity to the trustee against the costs, expenses and other liabilities of taking that action;

•

the trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity; and

•

the trustee must not have received from direct holders of a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with the written notice during the 60 day period after receipt of the above notice.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date.

Modification

There are three types of changes we can make to the indentures and the debt securities.

Changes Requiring Your Approval

First, there are changes that cannot be made to the indentures or your debt securities without your specific approval. Following is a list of those types of changes:

•

change the payment due date;

•

reduce any amounts due on a debt security;

•

change the place or currency of payment on a debt security;

•

impair your right to sue for payment;

•

waive a default in payment on a debt security;

•

reduce the percentage in principal amount of debt securities, the consent of whose holders is required to modify or amend the indenture;

•

reduce the percentage in principal amount of debt securities, the consent of whose holders is required to waive compliance with certain provisions of the indenture or to waive certain defaults; and

•

modify any other aspect of the provisions dealing with modification and waiver of the indenture.

- 10 -

Changes Requiring a Majority Vote

The second type of change to the indentures and the debt securities is the kind that requires consent of the holders of a majority in principal amount of the outstanding debt securities of the particular series affected. With a majority vote, the holders may waive past defaults, provided that such defaults are not of the type described previously under “Changes Requiring Your Approval.”

Changes Not Requiring Approval

The third type of change does not require any vote by direct holders of debt securities. This type is limited to clarifications and certain other changes that would not adversely affect holders of the debt securities.

Consolidation, Merger And Sale Of Assets

Infinity may consolidate or merge with or into another entity, and Infinity may sell or lease substantially all of its assets to another entity if the following conditions, among others, are met:

•

where Infinity merges out of existence or sells or leases substantially all its assets, the other entity must be a corporation organized and validly existing under the laws of the United States or any jurisdiction of the United States, and it must agree to be legally responsible for the debt securities; and

•

the merger, sale of assets or other transaction must not cause a default or an event of default on the debt securities.

Form, Exchange, Registration And Transfer

Generally, we will issue debt securities only in registered global form. See “Global Securities” below. However, if specified in the prospectus supplement, we may issue certificated securities in definitive form.

You may have your debt securities broken into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an “exchange.”

You may exchange or transfer debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may appoint another entity or perform this role itself. The entity performing the role of maintaining the list of registered direct holders is called the “security registrar.” It will also perform transfers. You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If the debt securities are redeemable and we redeem less than all of the debt securities of a particular series, we may block the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of debt securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed.

- 11 -

Global Securities

The debt securities of any series may be represented, in whole or in part, by one or more global securities. Each global security will:

•

be registered in the name of a depositary that we will identify in a prospectus supplement;

•

be deposited with the depositary or its nominee or custodian; and

•

bear any required legends.

No global security may be exchanged in whole or in part for debt securities registered in the name of any person other than the depositary or any nominee unless:

•

the depositary has notified us that it is unwilling or unable to continue as depositary or has ceased to be qualified to act as depositary;

•

we elect for any reason in our sole discretion to issue certificated debt securities in exchange for all of any portion of the global debt securities; or

•

any other circumstances described in a prospectus supplement occur.

As long as the depositary, or its nominee, is the registered owner of a global security, the depositary or nominee will be considered the sole owner and holder of the debt securities represented by the global security for all purposes under the indenture. Except in the above limited circumstances, owners of beneficial interests in a global security:

•

will not be entitled to have the debt securities registered in their names;

•

will not be entitled to physical delivery of certificated debt securities; and

•

will not be considered to be holders of those debt securities under the indenture.

Payments on a global security will be made to the depositary or its nominee as the holder of the global security. Some jurisdictions have laws that require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

Institutions that have accounts with the depositary or its nominee are referred to as “participants.” Ownership of beneficial interests in a global security will be limited to participants and to persons that may hold beneficial interests through participants. The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants. Each person owning a beneficial interest in a global security must rely on the procedures of the depositary (and, if such person is not a participant, on procedures of the participant through which such person owns its interest) to exercise any rights of a holder under the indenture.

Ownership of beneficial interests in a global security will be shown on and effected through records maintained by the depositary, with respect to participants’ interests, or by any participant, with respect to interests of persons held by participants on their behalf. Payments, transfers and exchanges relating to beneficial interests in a global security will be subject to policies and procedures of the depositary. The depositary policies and procedures may change from time to time. Neither we nor the trustee will have any responsibility or liability for the depositary’s or any participant’s records with respect to beneficial interests in a global security.

Notices

Notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the security register.

Infinity may issue junior subordinated debt securities under a junior subordinated indenture, as supplemented from time to time, between Infinity and U.S. Bank National Association, a form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Because the following summary of the material terms and provisions of the junior subordinated indenture and the related junior subordinated debt securities is not complete, you should refer to the forms of the documents for complete information regarding their terms and provisions, including the definitions of some of the terms used below.

The applicable prospectus supplement will describe the specific terms of the junior subordinated debt securities which we will offer, including:

•

the specific title and designation, aggregate principal amount and any limit on that amount, purchase price and denominations of the junior subordinated debt securities;

•

the date or dates on which the principal of the junior subordinated debt securities is payable or the method of determining the same, if applicable;

•

the rate or rates, which may be fixed or variable, at which the junior subordinated debt securities will bear interest, if any, or the method of determining the same, if applicable;

•

the date or dates from which the interest, if any, will accrue or the method of determining the same, if applicable, the interest payment dates, if any, on which interest will be payable or the manner of determining the same, if applicable, and the record dates for the determination of holders to whom interest is payable on the junior subordinated debt securities;

•

the duration of the maximum consecutive period that Infinity may elect to defer payments of interest on the junior subordinated debt securities;

•

any redemption, repayment or sinking fund provisions;

•

any applicable material United States federal income tax consequences; and

•

any other specific terms pertaining to the junior subordinated debt securities, whether in addition to, or modification or deletion of, the terms described in this prospectus.

Ranking

Each series of junior subordinated debt securities will rank equally with any other junior subordinated debt securities to be issued by Infinity and will be unsecured and will rank subordinate and junior in right of payment, to the extent and in the manner set forth in the junior subordinated indenture, to all senior indebtedness of Infinity, as defined in the junior subordinated indenture. The junior subordinated indenture will not limit the amount of secured or unsecured debt, including senior indebtedness, that may be incurred by us.

Modification of Junior Subordinated Indenture

From time to time, Infinity and the junior subordinated debt security trustee may, without the consent of the holders of the junior subordinated debt securities, amend, waive or supplement the junior subordinated indenture for specified purposes as set forth in the junior subordinated indenture.

Infinity and the junior subordinated debt security trustee may, with the consent of the holders of a majority in principal amount of all outstanding junior subordinated debt securities affected thereby, modify the junior subordinated indenture in a manner affecting the rights of the holders of junior subordinated debt securities; provided, however, that Infinity may not, without the consent of the holder of each outstanding junior subordinated debt security so affected, make any modifications which, among other things:

•

change the stated maturity of the principal of, or any installment of principal of or interest on (except as otherwise permitted), any junior subordinated debt security (other than pursuant its terms);

•

reduce the principal amount or the rate of interest on any junior subordinated debt security (or the amount of any installment of interest thereon) or change the method of calculating such rate or reduce any premium payable upon the redemption of any junior subordinated debenture; or

•

reduce the percentage in principal amount of the junior subordinated debt securities, the consent of the holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with any provision of the junior subordinated indenture or of any default under such junior subordinated indenture and its consequences, or reduce the requirements of the such junior subordinated indenture for quorum or voting.

Junior Subordinated Debt Security Events of Default

Each of the following events with respect to any series of junior subordinated debt securities will constitute a junior subordinated debt security event of default, whatever the reason for the junior subordinated debt security event of default and whether it is voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body, unless the event is specifically deleted or modified in or pursuant to the supplemental indenture, board resolution or officers’ certificate establishing the terms of the series pursuant to the junior subordinated indenture:

•

Infinity fails for 30 days to pay any interest or certain additional amounts on that series of junior subordinated debt securities when due, subject to any permitted deferral; provided that, during any extension period, failure to pay interest will not constitute a junior subordinated debt security event of default;

- 14 -

•

Infinity fails to pay any principal of or premium, if any, on the junior subordinated debt securities when due, whether at maturity, upon any redemption, by declaration of acceleration of maturity or otherwise;

•

Infinity fails to observe or perform any other agreement or covenant contained in the junior subordinated indenture in respect of that series of junior subordinated debt securities for 90 days after the debenture trustee or the holders of at least a majority in aggregate outstanding principal amount of that series of junior subordinated debt securities provides written notice to us; or

•

certain events in bankruptcy, insolvency or reorganization of Infinity.

The holders of a majority in aggregate outstanding principal amount of the junior subordinated debt securities have, subject to certain exceptions, the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee in respect of the junior subordinated debt securities. The junior subordinated debt security trustee or the holders of at least a majority in aggregate outstanding principal amount of the junior subordinated debt securities may declare the principal of and any accrued interest on the junior subordinated debt securities due and payable immediately upon a junior subordinated debt security event of default, except that a junior subordinated debt security event of default referred to in the last bullet point above will result in the immediate acceleration of the junior subordinated debt securities. The holders of a majority in aggregate outstanding principal amount of the junior subordinated debt securities may annul the declaration and waive the default in respect of the junior subordinated debt securities if the default, other than the non-payment of the principal and interest of the junior subordinated debt securities which has become due solely by the acceleration, has been cured and a sum sufficient to pay all matured installments of interest, and premium, if any, and principal due otherwise than by acceleration has been deposited with the junior subordinated debt security trustee.

The holders of a majority in aggregate outstanding principal amount of the junior subordinated debt securities may, on behalf of the holders of all of the junior subordinated debt securities, waive any past default, except a default in the payment of the principal of or premium, if any, or interest on, or additional amounts owing on a debenture, unless the default has been cured and a sum sufficient to pay all matured installments of interest, and premium, if any, and principal due otherwise than by acceleration has been deposited with the junior subordinated debt security trustee, or a default in respect of a covenant or provision which under the junior subordinated indenture cannot be modified or amended without the consent of the holder of each outstanding junior subordinated debt security of that series or a default in a conversion of exchange.

Enforcement of Certain Rights by Holders of Trust Preferred Securities

In the case of securities of a series issued to the Trust, any holder of the corresponding series of trust securities issued by the Trust shall have the right, upon the occurrence of an event

- 15 -

of default described in the junior subordinated indenture, to institute a direct action. A “direct action” is a legal proceeding directly against Infinity for enforcement of payment to the holder of the principal of or premium, if any, or interest on the junior subordinated debt securities having a principal amount equal to the liquidation amount of the trust preferred securities held by the holder or for enforcement of the conversion or exchange rights, as the case may be.

Consolidation, Merger, Sale of Assets and other Transactions

Infinity will not consolidate with or merge into any other person or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any person, and no person will consolidate with or merge into Infinity or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to Infinity, unless:

•

in case Infinity consolidates with or merges into another person or conveys or transfers its properties and assets as an entirety or substantially as an entirety to any person, the successor person is organized under the laws of the United States, any state of the United States or the District of Columbia, and the successor person expressly assumes Infinity’s obligations under the junior subordinated debt securities and the guarantee,

•

immediately after giving effect to the consolidation or merger, no debenture event of default, and no event which, after notice or lapse of time or both, would become a junior subordinated debt security event of default, will have occurred and be continuing, and

•

other conditions as prescribed in the junior subordinated indenture are met.

Satisfaction and Discharge

The junior subordinated indenture will cease to be of further effect, except as to our obligations to pay all other sums due under to the junior subordinated indenture and to provide the officers’ certificates and opinions of counsel described in that indenture, and we will be deemed to have satisfied and discharged the junior subordinated indenture, when, among other things, all junior subordinated debt securities not previously delivered to the debenture trustee for cancellation:

•

have become due and payable; or

•

will become due and payable at maturity or upon redemption within one year; and

•

Infinity deposits or causes to be deposited with the junior subordinated debt security trustee funds, in trust, for the purpose and in an amount sufficient to pay and discharge the entire indebtedness on the junior subordinated debt securities not previously delivered to the debenture trustee for cancellation, for the principal and premium, if any, and any other amounts due interest to the date of the deposit or to the stated maturity of the junior subordinated debt securities, as the case may be.

- 16 -

Subordination

The junior subordinated debt securities will rank subordinate and junior in right of payment to all senior indebtedness to the extent provided in the junior subordinated indenture. Upon any payment or distribution of assets to creditors upon any liquidation, dissolution, winding-up, reorganization, assignment for the benefit of creditors, marshaling of assets or any bankruptcy, insolvency, debt restructuring or similar proceedings in connection with any insolvency or bankruptcy proceeding of Infinity, the holders of senior indebtedness will first be entitled to receive payment in full of the senior indebtedness before the holders of junior subordinated debt securities will be entitled to receive or retain any payment in respect of these debentures.

In the event of the acceleration of the maturity of junior subordinated debt securities, the holders of all senior indebtedness outstanding at the time of the acceleration will first be entitled to receive payment in full of the senior indebtedness before the holders of junior subordinated debt securities will be entitled to receive or retain any payment in respect of the junior subordinated debt securities.

No payments on account of principal or premium, if any, or interest in respect of the junior subordinated debt securities may be made if:

•

there will have occurred and be continuing a default in any payment with respect to senior indebtedness;

•

any applicable grace period with respect to the default on the senior indebtedness has ended and the default has not been cured or waived or ceased to exist; or

•

any judicial proceeding is pending with respect to any default.

Governing Law

The junior subordinated indenture and the junior subordinated debt securities will be governed by and construed in accordance with the laws of the State of New York.

DESCRIPTION OF COMMON STOCK

This section summarizes the general terms of the common stock that Infinity may offer. The prospectus supplement relating to the common stock offered will set forth the number of shares offered, the initial offering price and recent market prices, dividend information and any other relevant information. The summary in this section and in the prospectus supplement does not describe every aspect of the common stock and is subject to and qualified in its entirety by reference to all the provisions of Infinity’s Amended and Restated Articles of Incorporation and Code of Regulations and to the provisions of the Ohio Revised Code.

The total number of authorized shares of common stock is 50,000,000. Holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of shareholders. Shareholders have the right to cumulate their votes in the election of directors.

Holders of common stock are entitled to receive dividends when and if declared by Infinity’s board of directors out of funds legally available therefor, subject to any contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred shares or debt securities.

Upon Infinity’s dissolution or liquidation or the sale of all or substantially all of Infinity’s assets, after payment in full of all amounts required to be paid to creditors and to the holders of preferred shares having liquidation preferences, if any, the holders of Infinity’s common stock will be entitled to receive pro rata Infinity’s remaining assets available for distribution.

As of June 30, 2010, Infinity had 12,847,127 shares of common stock outstanding. Shares of common stock carry no conversion or subscription rights and are not subject to redemption. All outstanding shares of common stock are, and any shares of common stock issued upon conversion of any convertible securities will be, fully paid and nonassessable.

DESCRIPTION OF PREFERRED STOCK

The following briefly summarizes the material terms of the preferred stock that Infinity may offer, other than pricing and related terms which will be disclosed in a prospectus supplement. You should read the particular terms of any series of preferred stock that Infinity offers, which Infinity will describe in more detail in any prospectus supplement relating to such series. You should also read the more detailed provisions of Infinity’s Amended and Restated Articles of Incorporation and the statement with respect to shares relating to each particular series of preferred stock for provisions that may be important to you. The statement with respect to shares relating to each particular series of preferred stock

- 18 -

offered by the accompanying prospectus supplement and this prospectus will be filed as an exhibit to a document incorporated by reference in the registration statement. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.

General

Infinity’s board of directors is authorized to issue up to 10,000,000 shares of preferred stock. As of the date of this prospectus, Infinity has not issued any shares of preferred stock. Infinity’s board of directors can issue shares of preferred stock in one or more series and can specify the following terms for each series:

•

the number of shares;

•

the designation, powers, preferences and rights of the shares; and

•

the qualifications, limitations or restrictions, except as otherwise stated in the articles of incorporation.

Before issuing any series of preferred stock, Infinity’s board of directors will adopt resolutions creating and designating the series as a series of preferred stock, and the resolutions will be filed in a statement with respect to shares as an amendment to the Amended and Restated Articles of Incorporation.

The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future. Infinity’s board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to Infinity’s officers, directors and employees and its subsidiaries pursuant to benefit plans or otherwise. The preferred stock could have the effect of acting as an anti-takeover device to prevent a change in control of Infinity.

Unless the particular prospectus supplement states otherwise, holders of each series of preferred stock will not have any preemptive or subscription rights to acquire more of Infinity’s stock.

The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.

Rank

Unless otherwise specified in the prospectus supplement relating to the shares of any series of preferred stock, the shares will rank on an equal basis with each other series of preferred stock and prior to the common stock as to dividends and distributions of assets.

Dividends

Unless the particular prospectus supplement states otherwise, holders of each series of preferred stock will be entitled to receive cash dividends, when, as and if declared by Infinity’s board of directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on Infinity’s books. Dividends on any series of preferred stock may be cumulative or noncumulative.

- 19 -

Infinity may not declare, pay or set apart for payment dividends on the preferred stock unless full dividends on any other series of preferred stock that ranks on an equal or senior basis have been paid or sufficient funds have been set apart for payment for:

•

all prior dividend periods of the other series of preferred stock that pay dividends on a cumulative basis; or

•

the immediately preceding dividend period of the other series of preferred stock that pay dividends on a noncumulative basis.

Partial dividends declared on shares of preferred stock and any other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for all such series of preferred stock.

Similarly, Infinity may not declare, pay or set apart for payment non-stock dividends or make other payments on the common stock or any other stock ranking junior to the preferred stock unless full dividends on all series of preferred stock have been paid or set apart for payment for:

•

all prior dividend periods if the preferred stock pays dividends on a cumulative basis; or

•

the immediately preceding dividend period if the preferred stock pays dividends on a noncumulative basis.

Conversion and Exchange

The prospectus supplement for any series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for shares of Infinity’s common stock.

Redemption

If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at Infinity’s option or at the option of the holders, or may be mandatorily redeemed.

Any partial redemptions of preferred stock will be made in a way that Infinity’s board of directors decides is equitable.

Unless Infinity default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

Liquidation Preference

Upon Infinity’s voluntary or involuntary liquidation, dissolution or winding up, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Such distributions will be made before any distribution is made on any securities ranking junior to the preferred stock with respect to liquidation, including common stock.

If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of Infinity’s available assets on a ratable basis in proportion to the full liquidation preferences. Holders of such series of preferred stock will not be entitled to any other amounts from Infinity after they have received their full liquidation preference.

- 20 -

Voting Rights

If Infinity issues voting preferred stock, holders of preferred stock will be entitled to one vote per share on each matter submitted to Infinity’s shareholders. If Infinity issues non-voting preferred stock, holders of preferred stock will have no voting rights, except as required by applicable law. The prospectus supplement will state the voting rights, if any, applicable to any particular series of preferred stock.

DESCRIPTION OF WARRANTS

Infinity may issue warrants for the purchase of common stock, debt securities or other securities registered pursuant to this registration statement and described in this prospectus. Infinity may issue warrants independently or together with other securities that may be attached to or separate from the warrants. Infinity will issue each series of warrants under a separate warrant agreement that will be entered into between Infinity and a bank or trust company, as warrant agent, and will be described in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as Infinity’s agent in connection with the warrant of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

DESCRIPTION OF DEPOSITARY SHARES

The following briefly summarizes the provisions of the depositary shares and depositary receipts that Infinity may issue from time to time and which would be important to holders of depositary receipts, other than pricing and related terms, which will be disclosed in the applicable prospectus supplement. The prospectus supplement will also state whether any of the general provisions summarized below do not apply to the depositary shares or depositary receipts being offered and provide any additional provisions applicable to the depositary shares or depositary receipts being offered. The following description and any description in a prospectus supplement may not be complete and are subject to, and qualified in their entirety by reference to the terms and provisions of the form of deposit agreement filed as an exhibit to the registration statement which contains this prospectus.

- 22 -

Depositary Shares

Infinity may offer depositary shares evidenced by depositary receipts. Each depositary share represents a fraction or a multiple of a share of a particular series of preferred stock that Infinity issues and deposits with a depositary. The fraction or the multiple of a share of preferred stock, which each depositary share represents, will be set forth in the applicable prospectus supplement.

Infinity will deposit the shares of any series of preferred stock represented by depositary shares according to the provisions of a deposit agreement to be entered into between Infinity and a bank or trust company, which Infinity will select as its preferred stock depositary. Infinity will name the depositary in the applicable prospectus supplement. Each holder of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock in proportion to the applicable fraction or multiple of a share of preferred stock represented by the depositary share. These rights include any applicable dividend, voting, redemption, conversion and liquidation rights. The depositary will send the holders of depositary shares all reports and communications that Infinity delivers to the depositary and which Infinity is required to furnish to the holders of depositary shares.

Depositary Receipts

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to anyone who is buying the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement.

Withdrawal of Preferred Stock

Unless the related depositary shares have previously been called for redemption, a holder of depositary shares may receive the number of whole shares of the related series of preferred stock and any money or other property represented by the holder’s depositary receipts after surrendering the depositary receipts at the corporate trust office of the depositary, paying any taxes, charges and fees provided for in the deposit agreement and complying with any other requirement of the deposit agreement. Partial shares of preferred stock will not be issued. If the surrendered depositary shares exceed the number of depositary shares that represent the number of whole shares of preferred stock the holder wishes to withdraw, then the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Once the holder has withdrawn the preferred stock, the holder will not be entitled to re-deposit that preferred stock under the deposit agreement or to receive depositary shares in exchange for such preferred stock.

Dividends and Other Distributions

The depositary will distribute to record holders of depositary shares any cash dividends or other cash distributions it receives on preferred stock. Each holder will receive these distributions in proportion to the number of depositary shares owned by the holder. The depositary will distribute only whole U.S. dollars and cents. The depositary will add any fractional cents not distributed to the next sum received for distribution to record holders of depositary shares.

In the event of a non-cash distribution, the depositary will distribute property to the record holders of depositary shares, unless the depositary determines that it is not feasible to make such a distribution. If this occurs, the depositary may, with Infinity’s approval, sell the property and distribute the net proceeds from the sale to the holders.

- 23 -

The amounts distributed to holders of depositary shares will be reduced by any amounts required to be withheld by the preferred stock depositary or by Infinity on account of taxes or other governmental charges.

Redemption of Depositary Shares

If the series of preferred stock represented by depositary shares is subject to redemption, then Infinity will give the necessary proceeds to the depositary. The depositary will then redeem the depositary shares using the funds it received from Infinity for the preferred stock. The redemption price per depositary share will be equal to the redemption price payable per share for the applicable series of the preferred stock and any other amounts per share payable with respect to the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. Whenever Infinity redeems shares of preferred stock held by the depositary, the depositary will redeem the depositary shares representing the shares of preferred stock on the same day, provided Infinity has paid in full to the depositary the redemption price of the preferred stock to be redeemed and any accrued and unpaid dividends. If fewer than all the depositary shares of a series are to be redeemed, the depositary shares will be selected by lot or ratably or by any other equitable method as the depositary will decide.

After the date fixed for redemption, the depositary shares called for redemption will no longer be considered outstanding. Therefore, all rights of holders of the depositary shares will cease, except that the holders will still be entitled to receive any cash payable upon the redemption and any money or other property to which the holder was entitled at the time of redemption. To receive this amount or other property, the holders must surrender the depositary receipts evidencing their depositary shares to the preferred stock depositary. Any funds that Infinity deposits with the preferred stock depositary for any depositary shares that the holders fail to redeem will be returned to Infinity after a period of two years from the date Infinity deposits the funds.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will notify holders of depositary shares of the upcoming vote and arrange to deliver Infinity’s voting materials to the holders. The record date for determining holders of depositary shares that are entitled to vote will be the same as the record date for the preferred stock. The materials the holders will receive will describe the matters to be voted on and explain how the holders, on a certain date, may instruct the depositary to vote the shares of preferred stock underlying the depositary shares. For instructions to be valid, the depositary must receive them on or before the date specified. To the extent possible, the depositary will vote the shares as instructed by the holder. Infinity agrees to take all reasonable actions that the depositary determines are necessary to enable it to vote as a holder has instructed. The depositary will abstain from voting shares of preferred stock deposited under a deposit agreement if it has not received specific instructions from the holder of the depositary shares representing those shares.

Amendment and Termination of the Deposit Agreement

Infinity may agree with the depositary to amend the deposit agreement and the form of depositary receipt at any time. However, any amendment that materially and adversely alters the rights of the holders of depositary receipts will not be effective unless it has been approved by the holders of at least a majority of the affected depositary shares then outstanding. Infinity will make no amendment that impairs the right of any holder of depositary shares, as described above under “– Withdrawal of Preferred Stock,” to receive shares of preferred stock and any money or other property represented by those depositary shares, except in order to comply with mandatory provisions of applicable law. If an amendment becomes effective, holders are deemed to agree to the amendment and to be bound by the amended deposit agreement if they continue to hold their depositary receipts.

- 24 -

The deposit agreement automatically terminates if a final distribution in respect of the preferred stock has been made to the holders of depositary receipts in connection with Infinity’s liquidation, dissolution or winding-up. Infinity may also terminate the deposit agreement at any time Infinity wishes with at least 60 days prior written notice to the depositary. If Infinity does so, the depositary will give notice of termination to the record holders not less than 30 days before the termination date. Once depositary receipts are surrendered to the depositary, it will send to each holder the number of whole or fractional shares of the series of preferred stock underlying that holder’s depositary receipts.

Charges of Depositary and Expenses

Infinity will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. Infinity will pay all charges of the depositary in connection with the initial deposit of the related series of offered preferred stock, the initial issuance of the depositary shares, all withdrawals of shares of the related series of offered preferred stock by holders of the depositary shares and the registration of transfers of title to any depositary shares. However, holders of depositary receipts will pay other taxes and governmental charges and any other charges provided in the deposit agreement to be payable by them.

Limitations on Infinity’s Obligations and Liability to Holders of Depositary Receipts

The deposit agreement will expressly limit Infinity’s obligations and the obligations of the depositary. It will also limit Infinity’s liability and the liability of the depositary as follows:

•

Infinity and the depositary are only liable to the holders of depositary receipts for negligence or willful misconduct; and

•

Infinity and the depositary have no obligation to become involved in any legal or other proceeding related to the depositary receipts or the deposit agreement on Infinity’s behalf or on behalf of any other party, unless you provide Infinity with satisfactory indemnity.

Resignation and Removal of Depositary

The depositary may resign at any time by notifying Infinity of its election to do so. In addition, Infinity may remove the depositary at any time. Within 60 days after the delivery of the notice of resignation or removal of the depositary, Infinity will appoint a successor depositary.

Reports to Holders

Infinity will deliver all required reports and communications to holders of the offered preferred stock to the depositary, and it will forward those reports and communications to the holders of depositary shares.

The following description and any description of the trust preferred securities and amended and restated declaration of trust in a prospectus supplement may not be complete and are subject to and qualified in their entirety by reference to the terms and provisions of the amended and restated declaration of trust, a form of which has been filed as an exhibit to the registration statement of which this prospectus forms a part.

General

The trust may issue only one series of trust preferred securities. We will describe these trust preferred securities in a prospectus supplement. The declaration of trust will be qualified as an indenture under the Trust Indenture Act and will contain the terms of the trust preferred securities.

- 26 -

The trust preferred securities will have terms, such as distributions, redemption, voting, liquidation rights and such other preferred, deferred or other special rights or such restrictions that are discussed in the declaration of trust or made part of the declaration of trust by the Trust Indenture Act or the Delaware Statutory Trust Act.

•

the voting rights, if any, of holders of trust preferred securities in addition to those required by law, including the number of votes per trust preferred security and any requirement for approval by the holders of such trust preferred securities, as a condition to specified action or amendments to the declaration of trust;

if applicable, any securities exchange upon which the trust preferred securities will be listed; and

We will guarantee distributions on trust preferred securities to the extent set forth below under “Description of the Trust Guarantee.” Certain United States federal income tax considerations applicable to trust preferred securities will be described in a prospectus supplement relating to the trust preferred securities.

In connection with the issuance of preferred securities, the trust will issue one series of common securities. The declaration of trust of the trust authorizes it to issue one series of common securities having such terms including distributions, redemption, voting, liquidation rights or such restrictions as shall be set forth in such declaration. The terms of the common securities issued by the trust will be substantially identical to the terms of the trust preferred securities issued by the trust and the common securities will rank equally, and payments will be made on a pro rata basis with the trust preferred securities. If an event of default occurs and is continuing, the rights of the holders of such common securities to payments in respect of distributions and payments upon liquidation, redemption and maturity will be subordinated to the rights of the holders of the trust preferred securities. Except in certain limited circumstances, the common securities issued by the trust will also carry the right to vote and to appoint, remove or replace any of the trustees of the trust. Infinity will own all of the common securities of the trust.

DESCRIPTION OF TRUST PREFERRED SECURITIES GUARANTEE

The following outlines some of the general terms and provisions of the trust preferred securities guarantee. Further terms of the guarantee, and the terms which differ from the discussion set forth below, will be provided in the applicable prospectus supplement. The following description and any description of the guarantee in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the guarantee agreements, forms of which have been or will be filed as exhibits to the registration statement of which this prospectus forms a part, and the Trust Indenture Act.

Infinity will execute and deliver a guarantee for the benefit of the holders of the trust preferred securities. The guarantee will be held by the guarantee trustee for the benefit of holders of the trust preferred securities to which it relates.

The guarantee will be qualified as an indenture under the Trust Indenture Act. U.S. Bank National Association will act as indenture trustee under the guarantee for purposes of the Trust Indenture Act.

General

We will irrevocably and unconditionally agree to pay in full, on a subordinated basis, to the holder of the trust preferred securities issued by the trust, the guarantee payments described in the next paragraph when due, regardless of any defense, right of set off or counterclaim that such trust may have.

- 28 -

Infinity will make the following payments on the trust preferred securities issued by a trust, to the extent not paid by or on behalf of such trust:

•

any accrued and unpaid distributions which the trust is required to pay on the trust preferred securities if the trust has sufficient funds to make such payments;

•

the amount payable upon redemption of the trust preferred securities, to the extent of funds held by the trust, for any preferred securities called for redemption by the trust; and

•

upon the liquidation of a trust, the lesser of

(a)

the aggregate of the liquidation amount and all accrued and unpaid distributions on the trust preferred securities to the date of payment, to the extent of funds held by such trust, and

(b)

the amount of assets of the trust remaining available for distribution to holders of trust preferred securities after the liquidation (other than in connection with the distribution of subordinated debt securities to the holders of the preferred securities of the trust in exchange for preferred securities as provided in the applicable declaration of trust).

We will make these payments either by directly paying the required amounts to the holders of the trust preferred securities or by causing the trust to make these payments.

Because the guarantee is a guarantee of payment and not of collection, you may proceed directly against Infinity as guarantor. You do not have to first proceed against the trust before attempting to collect from Infinity, and Infinity waives any right or remedy to require that any action be brought against a trust or any other person or entity before proceeding against Infinity. Infinity’s obligations will not be discharged except by payment of the guarantee payments in full.

If Infinity fails to make interest payments on the junior subordinated debt securities or pay amounts payable upon the redemption, acceleration or maturity of the junior subordinated debt securities held by the trust, the trust will have insufficient funds to pay distributions on or to pay amounts payable upon the redemption or repayment of such preferred securities. The guarantee does not cover payment of distributions or the amount payable upon redemption or repayment in respect of preferred securities when the trust does not have sufficient funds to pay these distributions or amounts.

Infinity has through the guarantee and certain back-up obligations, consisting of its obligations to provide certain indemnities in respect of, and pay and be responsible for, certain expenses, costs, liabilities and debts of the trust as set forth in the declaration, indenture and subordinated debentures, taken together, fully and unconditionally guaranteed all of the trust’s obligations under the preferred securities. No single document standing alone or operating in

- 29 -

conjunction with fewer than all of the other documents constitutes any such guarantee. It is only the combined operation of these documents that has the effect of providing full and unconditional guarantee of the trust’s obligations under the preferred securities.

Amendments and Assignment

Except with respect to any changes that do not adversely affect the rights of holders of trust preferred securities (in which case no vote will be required), the guarantee may be amended only with the prior approval of the holders of not less than a majority in liquidation amount of the outstanding trust preferred securities issued by the applicable trust. The guarantee and agreements contained in the guarantee will bind our successors, assignees, receivers, trustees and representatives and will inure to the benefit of the holders of the related trust preferred securities of the applicable trust then outstanding.

Termination of the Guarantee

The guarantee will terminate and will have no further force and effect as to the trust preferred securities upon full payment of the redemption price of all trust preferred securities, upon distribution of the subordinated debt securities to the holders of the trust preferred securities or upon full payment of the amounts payable in accordance with the declaration upon liquidation of the trust. The guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of trust preferred securities must restore payment of any sums paid under the trust preferred securities or the guarantee.

Status of the Guarantee; Subordination

The guarantee will constitute Infinity’s unsecured obligation and will rank:

•

subordinate and junior in right of payment to all of Infinity’s liabilities, except any liabilities that may be made pari passu expressly by their terms; and

•

senior to our common stock.

Upon Infinity’s bankruptcy, liquidation or winding up, its obligations under the guarantee will rank junior to all its other liabilities (except as described above) and, therefore, Infinity may not have enough funds for payments under the guarantee.

The declaration of trust provides that each holder of preferred securities by acceptance thereof agrees to the subordination provisions and other terms of the applicable guarantee.

Information Concerning the Guarantee Trustee

The guarantee trustee, prior to the occurrence of a default under the guarantee, undertakes to perform only those duties that are specifically set forth in the guarantee and, after such a default, shall exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to such provision, the guarantee trustee is under no obligation to exercise any of the powers vested in it by the guarantee at the request of any holder

- 30 -

of preferred securities unless it is offered security and indemnity satisfactory to the guarantee trustee against the costs, expenses and liabilities that might be incurred thereby.

Governing Law

The guarantee will be governed by and construed in accordance with the laws of the State of New York.

DESCRIPTION OF UNITS

We may, from time to time, issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date.

- 31 -

Any applicable prospectus supplement will describe:

•

the material terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

•

any material provisions relating to the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

Any delayed delivery contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the applicable prospectus supplement will set forth any commissions Infinity and/or the trust pay for solicitation of these delayed delivery contracts.

No assurance can be given as to the liquidity of the trading market for any of the offered securities.

Infinity or the trust may sell equity securities in an offering “at the market” as defined in Rule 415 under the Securities Act. A post-effective amendment to this registration statement will be filed to identify the underwriter(s) at the time of the take-down for “at the market” offerings.
