The Offering
 
Issuer NiSource Finance Corp.
 
Securities Offered $500,000,000 aggregate principal amount of 6.125% Notes due 2022.
 
Guarantee NiSource Inc. will fully and unconditionally guarantee all the obligations of NiSource Finance under the Notes.
 
Maturity Date The Notes will mature on March 1, 2022.
 
Interest Rate The interest rate on the Notes will be 6.125% per annum.
 
Interest Payment Dates Each March 1 and September 1, beginning March 1, 2010.
 
Optional Redemption We may redeem all or part of the Notes at any time at our option at a redemption price equal to the greater of (1) the principal amount of the notes being redeemed plus accrued interest to the redemption date and (2) a “make-whole” amount based on the yield of a comparable U.S. Treasury security plus 0.45%.
 
Ranking The Notes will be senior, unsecured obligations of NiSource Finance ranking equally in right of payment with other senior indebtedness of NiSource Finance.
 
The guarantees will be senior, unsecured obligations of NiSource, ranking equally in right of payment with other senior indebtedness of NiSource. Because NiSource is a holding company that derives substantially all of its income from operating subsidiaries, the guarantee will effectively be subordinated to debt and preferred stock at the subsidiary level.
 
The Indenture does not limit the amount of debt that NiSource Finance, NiSource or any of its subsidiaries may incur.
 
Limitation on Liens Subject to certain exceptions, neither NiSource Finance, NiSource nor any subsidiary of NiSource other than a utility may issue, assume or guarantee any secured debt, except intercompany indebtedness, without also securing the Notes, unless the total amount of all of the secured debt would not exceed 10% of our consolidated net tangible assets.
 
Use of Proceeds The net proceeds to us from the sale of the Notes, after deducting the underwriting discount but before deducting other fees and expenses related to the offering, will be approximately $494.5 million, of which we will lend $120 million to our subsidiary Northern Indiana Public Service Company to refinance a portion of the purchase price of the Sugar Creek generating facility it bought in 2008. The balance of the proceeds will be applied toward the repayment of $385 million of bank borrowings having an annual interest rate of 4.25% as of September 30, 2009 under our term loan facility that was used for working capital and matures on February 11, 2011.

RISK FACTORS
 
Investing in the Notes involves risk. Please see the “Risk Factors” and “Note Regarding Forward-Looking Statements” sections in NiSource’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008 and in our Quarterly Reports on Form 10-Q for the quarters ended June 30 and September 30, 2009, which are incorporated by reference in this prospectus supplement and the accompanying prospectus. Before making an investment decision, you should carefully consider these risks as well as other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. The risks and uncertainties not presently known to NiSource or that NiSource currently deems immaterial may also impair its business operations, its financial results and the value of the Notes. In addition, the risk described below could result in a decrease in the value of the Notes and your investment therein.
 
The Notes and guarantees are obligations of NiSource Finance and NiSource, respectively, and not of our operating subsidiaries and will be effectively subordinated to the claims of the operating subsidiaries’ creditors.
 
The Notes and guarantees are obligations of NiSource Finance and NiSource, respectively, and not of our other subsidiaries. NiSource is a holding company and, accordingly, we conduct substantially all of our operations through our operating subsidiaries. NiSource Finance is a consolidated finance subsidiary, which has no independent operations other than its financing activities. As a result, our cash flow and our ability to service our debt, including the Notes, depend upon the earnings of our operating subsidiaries and on the distribution of earnings, loans or other payments by such subsidiaries to NiSource and NiSource Finance.
 
Our operating subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on the Notes or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or other payments. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions. Payments to us by our operating subsidiaries will also be contingent upon such subsidiaries’ earnings and business considerations. As of September 30, 2009, our operating subsidiaries (which do not include NiSource Finance and NiSource Capital Markets, Inc.) had approximately $470.9 million of indebtedness.
 
Our right to receive any assets of any of our subsidiaries upon their liquidation or reorganization, and therefore the rights of the holders of the Notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors. In addition, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us. If any of our subsidiaries were to issue preferred stock in the future, the Notes would similarly be effectively subordinated to the rights of the preferred stockholders.

RATIOS OF EARNINGS TO FIXED CHARGES
 
The following are ratios of our earnings to fixed charges for each of the periods indicated:
 
                                             
    Fiscal Year Ended December 31,
Nine Months Ended September 30, 2009
  2008   2007   2006   2005   2004
 
  1.76       2.31       2.14       2.30       1.95       2.59  
 
For purposes of calculating the ratio of earnings to fixed charges, “earnings” consist of income from continuing operations before income taxes plus fixed charges. “Fixed charges” consist of interest on all indebtedness, amortization of debt expense, the portion of rental expenses on operating leases deemed to be representative of the interest factor and preferred stock dividend requirements of consolidated subsidiaries.

SUPPLEMENTAL DESCRIPTION OF THE NOTES
 
Please read the following information concerning the Notes in conjunction with the statements under “Description of the Debt Securities” in the accompanying prospectus, which the following information supplements and, if there are any inconsistencies, supersedes. The following description is not complete. The Notes will be issued under the Indenture, dated November 14, 2000, that we have entered into with The Bank of New York Mellon (as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as trustee. The Indenture is described in the accompanying prospectus and is filed as an exhibit to the registration statement under which the Notes are being offered and sold.
 
Maturity, Interest and Payment
 
The Notes will mature on March 1, 2022. The Notes will bear interest at a rate of 6.125% per annum from and including December 4, 2009, payable semi-annually in arrears on March 1 and September 1 of each year, beginning March 1, 2010. Interest payable on each interest payment date for the Notes will be paid to the persons in whose name the Notes are registered at the close of business on each February 15 and August 15.
 
If an interest payment date falls on a day that is not a business day, interest will be payable on the next succeeding business day with the same force and effect as if made on such interest payment date. Interest on the Notes will be calculated on the basis of a 360-day year, consisting of twelve 30-day months.
 
Optional Redemption
 
We may redeem all or part of the Notes at any time at our option at a redemption price equal to the greater of (1) the principal amount of the Notes being redeemed plus accrued interest to the redemption date or (2) the Make-Whole Amount for the Notes being redeemed.
 
The following definitions apply to the Notes:
 
“Make-Whole Amount” means the sum, as determined by a Quotation Agent, of the present values of the principal amount of the Notes to be redeemed, together with scheduled payments of interest (exclusive of interest to the redemption date) from the redemption date to the maturity date of the Notes, in each case discounted to the redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued interest on the principal amount of the Notes being redeemed to the redemption date.
 
“Adjusted Treasury Rate” means, with respect to any redemption date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each case calculated on the third business day preceding the redemption date, plus 0.45%.
 
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the Notes that would be utilized, at the time of selection and in accordance with


S-8


Table of Contents

customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.
 
“Quotation Agent” means the Reference Treasury Dealer selected by us.
 
“Reference Treasury Dealer” means a primary U.S. Government securities dealer selected by us.
 
“Comparable Treasury Price” means, with respect to any redemption date, if clause (ii) of the definition of Adjusted Treasury Rate is applicable, the average of three, or such lesser number as is obtained by us, Reference Treasury Dealer Quotations for such redemption date.
 
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by a Reference Treasury Dealer, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to us by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.
 
Selection and Notice of Redemption
 
If we are redeeming less than all the Notes at any time, the trustee will select the Notes to be redeemed using a method it considers fair and appropriate.
 
We will redeem Notes in increments of $1,000. We will cause notices of redemption to be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each holder of Notes to be redeemed at its registered address.
 
If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. We will issue a Note in principal amount equal to the unredeemed portion of the original Note in the name of the holder thereof upon cancellation of the original Note. Notes called for redemption will become due on the date fixed for redemption. On or after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption.
 
Forms and Denominations
 
The Notes will be issued as one or more global securities in the name of a nominee of The Depository Trust Company and will be available only in book-entry form. See “Description of the Debt Securities — Book-Entry Issuance” in the accompanying prospectus. The Notes are available for purchase in multiples of $1,000.
 
Additional Notes
 
We may, without the consent of the holders of the Notes, create and issue additional Notes ranking equally with the Notes in all respects, including having the same CUSIP number, so that such additional Notes would be consolidated and form a single series with the Notes and would have the same terms as to status, redemption or otherwise as the Notes. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.

CERTAIN ERISA CONSIDERATIONS
 
The following is a summary of certain considerations associated with the purchase of Notes by employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or provisions under any federal, state, local non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code, and entities whose underlying assets are considered to include “plan assets” of such plans, accounts and arrangements (each, a “Plan”).
 
General Fiduciary Matters
 
ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the management or administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.
 
In considering an investment in the Notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any similar law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable similar laws.
 
Prohibited Transaction Issues
 
Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition or holding of Notes by an ERISA Plan with respect to which NiSource, NiSource Finance or an underwriter is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption. In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or “PTCEs,” that may apply to the acquisition and holding of the Notes. These class exemptions include PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, the statutory exemption (the “Statutory Exemption”) under Section 408(b)(17) of ERISA or Section 4975(d)(20) of the Code for certain prohibited transactions between a plan and a person or entity that is a party in interest to such plan solely by reason of providing services to the plan or an affiliation with a service provider (other than a party in interest that is a fiduciary with respect to the assets of the plan involved in the transaction, or an affiliate of such a fiduciary), provided that there is adequate consideration for the transaction, may be applicable to the acquisition and holding of the Notes. There can be no assurance that a particular purchase of Notes will satisfy all of the conditions of any such exemptions.
 
Because of the foregoing, the Notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a violation of any applicable similar laws.


S-10


Table of Contents

Representation
 
By acceptance of a Note, each purchaser and subsequent transferee of a Note will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire and hold the Note constitutes assets of any Plan, or (ii) the purchase and holding of the Note by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or violate any applicable similar laws.
 
The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the Notes on behalf of, or with the assets of, any Plan consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any similar laws to such investment and whether an exemption would be applicable to the purchase and holding of the Notes.

The underwriting agreement provides that the underwriters are obligated to purchase all of the Notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults the purchase commitments of non-defaulting underwriters may be increased or the offering of Notes may be terminated.
 
The underwriters propose to offer the Notes initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a selling concession of .400% of the principal amount per Note. The underwriters and selling group members may allow a discount of .250% of the principal amount per Note on sales to other broker/dealers. After the initial public offering, the underwriters may change the public offering price, selling concession and discount to broker/dealers.
 
We estimate that our total expenses for this offering, excluding the underwriting discount, will be approximately $150,000.
 
The Notes are a new issue of securities with no established trading market. One or more of the underwriters intends to make a secondary market for the Notes. However, they are not obligated to do so and may discontinue making a secondary market for the Notes at any time without notice. No assurance can be given as to how liquid the trading market for the Notes will be.
 
We have agreed to indemnify the underwriters against liabilities under the Securities Act of 1933, or contribute to payments which the underwriters may be required to make in that respect.
 
In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.
 
  •   Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specific maximum.
 
  •   Over-allotment involves sales by the underwriters of Notes in excess of the principal amount of Notes the underwriters are obligated to purchase, which creates a syndicate short position.
 
  •   Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover syndicate short positions. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the


S-12


Table of Contents

  price of the Notes in the open market after pricing that could adversely affect investors who purchase in the offering.
 
  •   Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the Notes originally sold by the syndicate member are purchased in a stabilizing transaction or a syndicate covering transaction to cover syndicate short positions.
 
These stabilizing transactions, syndicate-covering transactions and penalty bids may have the effect of raising or maintaining the market price of the Notes or preventing or retarding a decline in the market prices of the Notes. As a result the price of the Notes may be higher than the prices that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time.

RISK FACTORS
 
Investing in the securities involves risk.  Please see the “Risk Factors” and “Information Regarding Forward-Looking Statements” sections in NiSource’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006, along with the disclosure related to the risk factors contained in NiSource’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2007, June 30, 2007 and September 30, 2007, which are incorporated by reference in this prospectus. Before making an investment decision, you should carefully consider these risks as well as other information contained or incorporated by reference in this prospectus. The risks and uncertainties not presently known to NiSource or that NiSource currently deems immaterial may also impair its business operations, its financial results and the value of the securities. The prospectus supplement applicable to each type or series of securities we offer may contain a discussion of additional risks applicable to an investment in us and the particular type of securities we are offering under that prospectus supplement.
 
FORWARD-LOOKING STATEMENTS
 
Some of the information included in this prospectus, in any prospectus supplement and in the documents incorporated by reference are “forward-looking statements” within the meaning of the securities laws. Investors and prospective investors should understand that many factors govern whether any forward-looking statement contained herein will be or can be realized. Any one of those factors could cause actual results to differ materially from those projected. These forward-looking statements include, but are not limited to, statements concerning NiSource’s plans, objectives, expected performance, expenditures and recovery of expenditures through rates, stated on either a consolidated or segment basis, and any and all underlying assumptions and other statements that are other than statements of historical fact. From time to time, NiSource may publish or otherwise make available forward-looking statements of this nature. All such subsequent forward-looking statements, whether written or oral and whether made by or on behalf of NiSource, are also expressly qualified by these cautionary statements. All forward-looking statements are based on assumptions that management believes to be reasonable; however, there can be no assurance that actual results will not differ materially.
 
Realization of NiSource’s objectives and expected performance is subject to a wide range of risks and can be adversely affected by, among other things, weather, fluctuations in supply and demand for energy commodities, growth opportunities for NiSource’s businesses, increased competition in deregulated energy markets, the success

Table of Contents

of regulatory and commercial initiatives, dealings with third parties over whom NiSource has no control, actual operating experience of NiSource’s assets, the regulatory process, regulatory and legislative changes, changes in general economic, capital and commodity market conditions, and counterparty credit risk, many of which risks are beyond the control of NiSource. In addition, the relative contributions to profitability by each segment, and the assumptions underlying the forward-looking statements relating thereto, may change over time.
 
Accordingly, you should not rely on the accuracy of predictions contained in forward-looking statements. These statements speak only as of the date of this prospectus, the date of the accompanying prospectus supplement or, in the case of documents incorporated by reference, the date of those documents.

USE OF PROCEEDS

RATIOS OF EARNINGS TO FIXED CHARGES
 
The following are ratios of our earnings to fixed charges for each of the periods indicated:
 
                                         
Nine Months Ended
  Fiscal Year Ended December 31  
September 31, 2007
  2006     2005     2004     2003     2002  
 
2.31
    2.22       1.95       2.55       2.29       2.07  
 
For purposes of calculating the ratio of earnings to fixed charges, “earnings” consist of income from continuing operations before income taxes plus fixed charges. “Fixed charges” consist of interest on all indebtedness, amortization of debt expense, the portion of rental expenses on operating leases deemed to be representative of the interest factor and preferred stock dividend requirements of consolidated subsidiaries.
 
DESCRIPTION OF CAPITAL STOCK
 
General
 
The authorized capital stock of NiSource consists of 420,000,000 shares, $0.01 par value, of which 400,000,000 are common stock and 20,000,000 are preferred stock. The board of directors has designated 4,000,000 shares of the preferred stock as Series A Junior Participating Preferred Shares. These shares were reserved for issuance upon the exercise of rights under NiSource’s Shareholder Rights Plan. As of November 29, 2006, no rights may be exercised under NiSource’s Shareholder Rights Plan.
 
Anti-Takeover Provisions
 
The certificate of incorporation of NiSource includes provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control of management of NiSource. Members of NiSource’s board of directors may be removed only for cause by the affirmative vote of 80% of the combined voting power of all of the then-outstanding shares of stock of NiSource voting together as a single class. Unless the board of directors determines otherwise or except as otherwise required by law, vacancies on the board or newly-created directorships may be filled only by the affirmative vote of directors then in office, even though less than a quorum. If the board of


5


Table of Contents

directors or applicable Delaware law confers power on stockholders of NiSource to fill such a vacancy or newly-created directorship, it may be filled only by affirmative vote of 80% of the combined voting power of the outstanding shares of stock of NiSource entitled to vote. Stockholders may not cumulate their votes, and stockholder action may be taken only at a duly called meeting and not by written consent. In addition, NiSource’s bylaws provide that special meetings of stockholders may be called only by a majority of the total number of authorized directors and contain requirements for advance notice of stockholder proposals and director nominations. These and other provisions of the certificate of incorporation and bylaws and Delaware law could discourage potential acquisition proposals and could delay or prevent a change in control of management of NiSource.
 
NiSource is subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. Section 203 prevents certain Delaware corporations, including those whose securities are listed on a national securities exchange, such as the New York Stock Exchange, from engaging, under certain circumstances, in a “business combination,” which includes a merger or sale of more than 10% of the corporation’s assets, with any interested stockholder for three years following the date that the stockholder became an interested stockholder. An interested stockholder is a stockholder who acquired 15% or more of the corporation’s outstanding voting stock without the prior approval of the corporation’s board of directors.
 
The following summaries of provisions of our common stock and preferred stock are not necessarily complete. You are urged to read carefully NiSource’s certificate of incorporation and bylaws which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part.
 
Common Stock
 
NiSource common stock is listed on the New York Stock Exchange under the symbol “NI.” Common stockholders may receive dividends if and when declared by the board of directors. Dividends may be paid in cash, stock or other form. In certain cases, common stockholders may not receive dividends until obligations to any preferred stockholders have been satisfied. All common stock will be fully paid and non-assessable. Each share of common stock is entitled to one vote in the election of directors and other matters. Common stockholders are not entitled to preemptive rights or cumulative voting rights. Common stockholders will be notified of any stockholders’ meeting according to applicable law. If NiSource liquidates, dissolves or winds-up its business, either voluntarily or involuntarily, common stockholders will share equally in the assets remaining after creditors and preferred stockholders are paid.
 
Preferred Stock
 
The board of directors can, without approval of stockholders, issue one or more series of preferred stock. The board can also determine the number of shares of each series and the rights, preferences and limitations of each series, including any dividend rights, voting rights, conversion rights, redemption rights and liquidation preferences, the number of shares constituting each series and the terms and conditions of issue. In some cases, the issuance of preferred stock could delay a change in control of NiSource and make it harder to remove incumbent management. Under certain circumstances, preferred stock could also restrict dividend payments to holders of common stock. All preferred stock will be fully paid and non-assessable.
 
The terms of the preferred stock that NiSource may offer will be established by or pursuant to a resolution of the board of directors of NiSource and will be issued under certificates of designations or through amendments to NiSource’s certificate of incorporation. If NiSource uses this prospectus to offer preferred stock, an accompanying prospectus supplement will describe the specific terms of the preferred stock. NiSource will also indicate in the supplement whether the general terms and provisions described in this prospectus apply to the preferred stock that NiSource may offer.
 
The following terms of the preferred stock, as applicable, will be set forth in a prospectus supplement relating to the preferred stock:
 
  •  the title and stated value;
 
  •  the number of shares NiSource is offering;
 
  •  the liquidation preference per share;

Table of Contents

 
  •  the purchase price;
 
  •  the dividend rate, period and payment date, and method of calculation of dividends;
 
  •  whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;
 
  •  the procedures for any auction and remarketing, if any;
 
  •  the provisions for a sinking fund, if any;
 
  •  the provisions for redemption or repurchase, if applicable, and any restrictions on NiSource’s ability to exercise those redemption and repurchase rights;
 
  •  any listing of the preferred stock on any securities exchange or market;
 
  •  voting rights, if any;
 
  •  preemptive rights, if any;

  •  whether interests in the preferred stock will be represented by depositary shares;
 
  •  a discussion of any material or special United States federal income tax considerations applicable to the preferred stock;
 
  •  the relative ranking and preferences of the preferred stock as to dividend or liquidation rights;
 
  •  any limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend or liquidation rights; and
 
  •  any other material specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.
 
The terms, if any, on which the preferred stock may be exchanged for or converted into shares of common stock or any other security and, if applicable, the conversion or exchange price, or how it will be calculated, and the conversion or exchange period will be set forth in the applicable prospectus supplement.
 
The preferred stock or any series of preferred stock may be represented, in whole or in part, by one or more global certificates, which will have an aggregate liquidation preference equal to that of the preferred stock represented by the global certificate.
 
Each global certificate will:
 
  •  be registered in the name of a depositary or a nominee of the depositary identified in the prospectus supplement;
 
  •  be deposited with such depositary or nominee or a custodian for the depositary; and
 
  •  bear a legend regarding the restrictions on exchanges and registration of transfer and any other matters as may be provided for under the certificate of designations.
 
DESCRIPTION OF THE DEBT SECURITIES
 
NiSource Finance may issue the debt securities, in one or more series, from time to time under an Indenture, dated as of November 14, 2000, among NiSource Finance, NiSource, as guarantor, and The Bank of New York (as successor to JPMorgan Chase Bank, formerly known as The Chase Manhattan Bank), as trustee. The Bank of New York, as trustee under the Indenture, will act as indenture trustee for the purposes of the Trust Indenture Act. We have incorporated by reference the Indenture as an exhibit to the registration statement of which this prospectus is a part.
 
This section briefly summarizes some of the terms of the debt securities and the Indenture. This section does not contain a complete description of the debt securities or the Indenture. The description of the debt securities is


7


Table of Contents

qualified in its entirety by the provisions of the Indenture. References to section numbers in this description of the debt securities, unless otherwise indicated, are references to section numbers of the Indenture.
 
General
 
The Indenture does not limit the amount of debt securities that may be issued. The Indenture provides for the issuance of debt securities from time to time in one or more series. The terms of each series of debt securities may be established in a supplemental indenture or in resolutions of NiSource Finance’s board of directors or a committee of the board.
 
The debt securities:
 
  •  are direct senior unsecured obligations of NiSource Finance;
 
  •  are equal in right of payment to any other senior unsecured obligations of NiSource Finance; and
 
  •  are guaranteed on a senior unsecured basis by NiSource.
 
NiSource Finance is a special purpose financing subsidiary formed solely as a financing vehicle for NiSource and its subsidiaries. Therefore, the ability of NiSource Finance to pay its obligations under the debt securities is dependent upon the receipt by it of payments from NiSource. If NiSource were not to make such payments for any reason, the holders of the debt securities would have to rely on the enforcement of NiSource’s guarantee described below.
 
If NiSource Finance uses this prospectus to offer debt securities, an accompanying prospectus supplement will describe the following terms of the debt securities being offered, to the extent applicable:
 
  •  the title;
 
  •  any limit on the aggregate principal amount;
 
  •  the date or dates on which NiSource Finance will pay principal;
 
  •  the right, if any, to extend the date or dates on which NiSource Finance will pay principal;
 
  •  the interest rates or the method of determining them and the date interest begins to accrue;
 
  •  the interest payment dates and the regular record dates for any interest payment dates;
 
  •  the right, if any, to extend the interest payment periods and the duration of any extension;
 
  •  the place or places where NiSource Finance will pay principal and interest;
 
  •  the terms and conditions of any optional redemption, including the date after which, and the price or prices at which, NiSource Finance may redeem securities;
 
  •  the terms and conditions of any optional purchase or repayment, including the date after which, and the price or prices at which, holders may require NiSource Finance to purchase, or a third party may require holders to sell, securities;
 
  •  the terms and conditions of any mandatory or optional sinking fund redemption, including the date after which, and the price or prices at which, NiSource Finance may redeem securities;
 
  •  whether bearer securities will be issued;
 
  •  the denominations in which NiSource Finance will issue securities;
 
  •  the currency or currencies in which NiSource Finance will pay principal and interest;
 
  •  any index or indices used to determine the amount of payments;
 
  •  the portion of principal payable on declaration of acceleration of maturity;
 
  •  any additional events of default or covenants of NiSource Finance or NiSource applicable to the debt securities;

Table of Contents

 
  •  whether NiSource Finance will pay additional amounts in respect of taxes and similar charges on debt securities held by a United States alien and whether NiSource Finance may redeem those debt securities rather than pay additional amounts;
 
  •  whether NiSource Finance will issue the debt securities in whole or in part in global form and, in such case, the depositary for such global securities and the circumstances under which beneficial owners of interests in the global security may exchange such interest for securities;
 
  •  the date or dates after which holders may convert the securities into shares of NiSource common stock or preferred stock and the terms for that conversion; and
 
  •  any other terms of the securities.
 
The Indenture does not give holders of debt securities protection in the event of a highly leveraged transaction or other transaction involving NiSource Finance or NiSource. The Indenture also does not limit the ability of NiSource Finance or NiSource to incur indebtedness or to declare or pay dividends on its capital stock.
 
Guarantee of NiSource
 
NiSource will fully and unconditionally guarantee to each holder of debt securities and to the indenture trustee and its successors all the obligations of NiSource Finance under the debt securities, including the due and punctual payment of the principal of, and premium, if any, and interest, if any, on the debt securities. The guarantee applies whether the payment is due at maturity, on an interest payment date or as a result of acceleration, redemption or otherwise. The guarantee includes payment of interest on the overdue principal of and interest, if any, on the debt securities (if lawful) and all other obligations of NiSource Finance under the Indenture. The guarantee will remain valid even if the Indenture is found to be invalid. NiSource is obligated under the guarantee to pay any guaranteed amount immediately after NiSource Finance’s failure to do so.
 
NiSource is a holding company with no independent business operations or source of income of its own. It conducts substantially all of its operations through its subsidiaries and, as a result, NiSource depends on the earnings and cash flow of, and dividends or distributions from, its subsidiaries to provide the funds necessary to meet its debt and contractual obligations. A substantial portion of NiSource’s consolidated assets, earnings and cash flow is derived from the operation of its regulated utility subsidiaries, whose legal authority to pay dividends or make other distributions to NiSource is subject to regulation. Northern Indiana Public Service Company’s debt indenture also provides that Northern Indiana Public Service Company will not declare or pay any dividends on its common stock owned by NiSource except out of earned surplus or net profits.
 
NiSource’s holding company status also means that its right to participate in any distribution of the assets of any of its subsidiaries upon liquidation, reorganization or otherwise is subject to the prior claims of the creditors of each of the subsidiaries (except to the extent that the claims of NiSource itself as a creditor of a subsidiary may be recognized). Since this is true for NiSource, it is also true for the creditors of NiSource (including the holders of the debt securities).
 
Conversion Rights
 
The terms, if any, on which a series of debt securities may be exchanged for or converted into shares of common stock or preferred stock of NiSource will be set forth in the applicable prospectus supplement.
 
Denomination, Registration and Transfer
 
NiSource Finance may issue the debt securities as registered securities in certificated form or as global securities as described under the heading “Book-Entry Issuance.” Unless otherwise specified in the applicable prospectus supplement, NiSource Finance will issue registered debt securities in denominations of $1,000 or integral multiples of $1,000. (See Section 302.)
 
If NiSource Finance issues the debt securities as registered securities, NiSource Finance will keep at one of its offices or agencies a register in which it will provide for the registration and transfer of the debt securities. NiSource

Table of Contents

Finance will appoint that office or agency the security registrar for the purpose of registering and transferring the debt securities.
 
The holder of any registered debt security may exchange the debt security for registered debt securities of the same series having the same stated maturity date and original issue date, in any authorized denominations, in like tenor and in the same aggregate principal amount. The holder may exchange those debt securities by surrendering them in a place of payment maintained for this purpose at the office or agency NiSource Finance has appointed securities registrar. Holders may present the debt securities for exchange or registration of transfer, duly endorsed or accompanied by a duly executed written instrument of transfer satisfactory to NiSource Finance and the securities registrar. No service charge will apply to any exchange or registration of transfer, but NiSource Finance may require payment of any taxes and other governmental charges as described in the Indenture. (See Section 305.)
 
If debt securities of any series are redeemed, NiSource Finance will not be required to issue, register transfer of or exchange any debt securities of that series during the 15 business day period immediately preceding the day the relevant notice of redemption is given. That notice will identify the serial numbers of the debt securities being redeemed. After notice is given, NiSource Finance will not be required to issue, register the transfer of or exchange any debt securities that have been selected to be either partially or fully redeemed, except the unredeemed portion of any debt security being partially redeemed. (See Section 305.)
 
Payment and Paying Agents
 
Unless otherwise indicated in the applicable prospectus supplement, on each interest payment date, NiSource Finance will pay interest on each debt security to the person in whose name that debt security is registered as of the close of business on the record date relating to that interest payment date. If NiSource Finance defaults in the payment of interest on any debt security, it may pay that defaulted interest to the registered owner of that debt security:
 
  •  as of the close of business on a date that the indenture trustee selects, which may not be more than 15 days or less than 10 days before the date NiSource Finance proposes to pay the defaulted interest, or
 
  •  in any other lawful manner that does not violate the requirements of any securities exchange on which that debt security is listed and that the indenture trustee believes is acceptable.
 
(See Section 307.)
 
Unless otherwise indicated in the applicable prospectus supplement, NiSource Finance will pay the principal of and any premium or interest on the debt securities when they are presented at the office of the indenture trustee, as paying agent. NiSource Finance may change the place of payment of the debt securities, appoint one or more additional paying agents, and remove any paying agent.
 
Redemption
 
The applicable prospectus supplement will contain the specific terms on which NiSource Finance may redeem a series of debt securities prior to its stated maturity. NiSource Finance will send a notice of redemption to holders at least 30 days but not more than 60 days prior to the redemption date. The notice will state:
 
  •  the redemption date;
 
  •  the redemption price;
 
  •  if less than all of the debt securities of the series are being redeemed, the particular debt securities to be redeemed (and the principal amounts, in the case of a partial redemption);
 
  •  that on the redemption date, the redemption price will become due and payable and any applicable interest will cease to accrue on and after that date;
 
  •  the place or places of payment; and
 
  •  whether the redemption is for a sinking fund.


10


Table of Contents

 
(See Section 1104.)
 
On or before any redemption date, NiSource Finance will deposit an amount of money with the indenture trustee or with a paying agent sufficient to pay the redemption price. (See Section 1105.)
 
If NiSource Finance is redeeming less than all the debt securities, the indenture trustee will select the debt securities to be redeemed using a method it considers fair and appropriate. After the redemption date, holders of redeemed debt securities will have no rights with respect to the debt securities except the right to receive the redemption price and any unpaid interest to the redemption date. (See Section 1103.)
 
Consolidation, Merger, Conveyance, Transfer or Lease
 
Neither NiSource Finance nor NiSource shall consolidate or merge with any other corporation or convey, transfer or lease substantially all of its assets or properties to any entity unless:
 
  •  that corporation or entity is organized under the laws of the United States or any state thereof;
 
  •  that corporation or entity assumes NiSource Finance’s or NiSource’s obligations, as applicable, under the Indenture;
 
  •  after giving effect to the transaction, NiSource Finance and NiSource are not in default under the Indenture; and
 
  •  NiSource Finance or NiSource, as applicable, delivers to the indenture trustee an officer’s certificate and an opinion of counsel to the effect that the transaction complies with the Indenture.
 
(See Section 801.)
 
Limitation on Liens
 
As long as any debt securities remain outstanding, neither NiSource Finance, NiSource nor any subsidiary of NiSource other than a utility may issue, assume or guarantee any debt secured by any mortgage, security interest, pledge, lien or other encumbrance on any property owned by NiSource Finance, NiSource or that subsidiary, except intercompany indebtedness, without also securing the debt securities equally and ratably with (or prior to) the new debt, unless the total amount of all of the secured debt would not exceed 10% of the consolidated net tangible assets of NiSource and its subsidiaries (other than utilities).
 
In addition, the lien limitations do not apply to NiSource Finance’s, NiSource’s and any subsidiary’s ability to do the following:
 
  •  create mortgages on any property and on certain improvements and accessions on such property acquired, constructed or improved after the date of the Indenture;
 
  •  assume existing mortgages on any property or indebtedness of an entity which is merged with or into, or consolidated with NiSource Finance, NiSource or any subsidiary;
 
  •  assume existing mortgages on any property or indebtedness of an entity existing at the time it becomes a subsidiary;
 
  •  create mortgages to secure debt of a subsidiary to NiSource or to another subsidiary;
 
  •  create mortgages in favor of governmental entities to secure payment under a contract or statute or mortgages to secure the financing of constructing or improving property, including mortgages for pollution control or industrial revenue bonds;
 
  •  create mortgages to secure debt of NiSource or its subsidiaries maturing within 12 months and created in the ordinary course of business;
 
  •  create mortgages to secure the cost of exploration, drilling or development of natural gas, oil or other mineral property;
 
  •  to continue mortgages existing on the date of the Indenture; and


11


Table of Contents

 
  •  create mortgages to extend, renew or replace indebtedness secured by any mortgage referred to above provided that the principal amount of indebtedness and the property securing the indebtedness shall not exceed the amount secured by the mortgage being extended, renewed or replaced.
 
(See Section 1008.)
 
Events of Default
 
The Indenture provides, with respect to any outstanding series of debt securities, that any of the following events constitutes an “Event of Default”:
 
  •  NiSource Finance defaults in the payment of any interest upon any debt security of that series that becomes due and payable and the default continues for 60 days;
 
  •  NiSource Finance defaults in the payment of principal of or any premium on any debt security of that series when due at its maturity, on redemption, by declaration or otherwise and the default continues for three business days;
 
  •  NiSource Finance defaults in the deposit of any sinking fund payment when due and the default continues for three business days;
 
  •  NiSource Finance or NiSource defaults in the performance of or breaches any covenant or warranty in the Indenture for 90 days after written notice to NiSource Finance and NiSource from the indenture trustee or to NiSource Finance, NiSource and the indenture trustee from the holders of at least 33% of the outstanding debt securities of that series;
 
  •  NiSource Finance or NiSource Capital Markets, Inc., a subsidiary of NiSource, defaults under any bond, debenture, note or other evidence of indebtedness for money borrowed by NiSource Finance or NiSource Capital Markets, or NiSource Finance or NiSource Capital Markets defaults under any mortgage, indenture or instrument under which there may be issued, secured or evidenced indebtedness constituting a failure to pay in excess of $50,000,000 of the principal or interest when due and payable, and in the event such debt has become due as the result of an acceleration, such acceleration is not rescinded or annulled or such debt is not paid within 60 days after written notice to NiSource Finance and NiSource from the indenture trustee or to NiSource Finance, NiSource and the indenture trustee from the holders of at least 33% of the outstanding debt securities of that series;
 
  •  the NiSource guarantee ceases to be in full force and effect in any material respect or is disaffirmed or denied (other than according to its terms), or is found to be unenforceable or invalid; or
 
  •  certain events of bankruptcy, insolvency or reorganization of NiSource Finance, NiSource Capital Markets or NiSource.
 
(See Section 501.)
 
If an Event of Default occurs with respect to debt securities of a particular series, the indenture trustee or the holders of 33% in principal amount of the outstanding debt securities of that series may declare the debt securities of that series due and payable immediately. (See Section 502.)
 
The holders of a majority in principal amount of the outstanding debt securities of a particular series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee under the Indenture, or exercising any trust or power conferred on the indenture trustee with respect to the debt securities of that series. The indenture trustee may refuse to follow directions that are in conflict with law or the Indenture, that expose the indenture trustee to personal liability or that are unduly prejudicial to other holders. The indenture trustee may take any other action it deems proper that is not inconsistent with those directions. (See Section 512.)
 
The holders of a majority in principal amount of the outstanding debt securities of any series may waive any past default under the Indenture and its consequences, except a default:
 
  •  in respect of a payment of principal of, or premium, if any, or interest on any debt security; or


12


Table of Contents

 
  •  in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each affected debt security.
 
(See Section 513.)
 
At any time after the holders of the debt securities of a series declare that the debt securities of that series are due and immediately payable, a majority in principal amount of the outstanding holders of debt securities of that series may rescind and cancel the declaration and its consequences: (1) before the indenture trustee has obtained a judgment or decree for money, (2) if all defaults (other than the non-payment of principal which has become due solely by reason of the declaration) have been waived or cured, and (3) NiSource or NiSource Finance has paid or deposited with the indenture trustee an amount sufficient to pay:
 
  •  all overdue interest on the debt securities of that series;
 
  •  the principal of, and premium, if any, or interest on any debt securities of that series which are due other than by reason of the declaration;
 
  •  interest on overdue interest (if lawful); and
 
  •  sums paid or advanced by and amounts due to the indenture trustee under the Indenture.
 
(See Section 502.)
 
Modification of Indenture
 
NiSource Finance, NiSource and the indenture trustee may modify or amend the Indenture, without the consent of the holders of any debt securities, for any of the following purposes:
 
  •  to evidence the succession of another person as obligor under the Indenture;
 
  •  to add to NiSource Finance’s or NiSource’s covenants or to surrender any right or power conferred on NiSource Finance or NiSource under the Indenture;
 
  •  to add events of default;
 
  •  to add or change any provisions of the Indenture to provide that bearer securities may be registrable as to principal, to change or eliminate any restrictions on the payment of principal or premium on registered securities or of principal or premium or any interest on bearer securities, to permit registered securities to be exchanged for bearer securities or to permit the issuance of securities in uncertificated form (so long as the modification or amendment does not materially adversely affect the interest of the holders of debt securities of any series);
 
  •  to change or eliminate any provisions of the Indenture (so long as there are no outstanding debt securities entitled to the benefit of the provision);
 
  •  to secure the debt securities;
 
  •  to establish the form or terms of debt securities of any series;
 
  •  to evidence or provide for the acceptance or appointment by a successor indenture trustee or facilitate the administration of the trusts under the Indenture by more than one indenture trustee;
 
  •  to cure any ambiguity, defect or inconsistency in the Indenture (so long as the cure or modification does not materially adversely affect the interest of the holders of debt securities of any series);
 
  •  to effect assumption by NiSource or one of its subsidiaries of NiSource Finance’s obligations under the Indenture; or
 
  •  to conform the Indenture to any amendment of the Trust Indenture Act.
 
(See Section 901.)

Table of Contents

The Indenture provides that we and the indenture trustee may amend the Indenture or the debt securities with the consent of the holders of a majority in principal amount of the then outstanding debt securities of each series affected by the amendment voting as one class. However, without the consent of each holder of any outstanding debt securities affected, an amendment or modification may not, among other things:
 
  •  change the stated maturity of the principal or interest on any debt security;
 
  •  reduce the principal amount of, rate of interest on, or premium payable upon the redemption of, any debt security;
 
  •  change the method of calculating the rate of interest on any debt security;
 
  •  change any obligation of NiSource Finance to pay additional amounts in respect of any debt security;
 
  •  reduce the principal amount of a discount security that would be payable upon acceleration of its maturity;
 
  •  change the place or currency of payment of principal of, or any premium or interest on, any debt security;
 
  •  impair a holder’s right to institute suit for the enforcement of any payment after the stated maturity or after any redemption date or repayment date;
 
  •  reduce the percentage of holders of debt securities necessary to modify or amend the Indenture or to consent to any waiver under the Indenture;
 
  •  change any obligation of NiSource Finance to maintain an office or agency in each place of payment or to maintain an office or agency outside the United States;
 
  •  modify the obligations of NiSource under its guarantee in any way adverse to the interests of the holders of the debt securities; and
 
  •  modify these requirements or reduce the percentage of holders of debt securities necessary to waive any past default of certain covenants.
 
(See Section 902.)
 
Satisfaction and Discharge
 
Under the Indenture, NiSource Finance can terminate its obligations with respect to debt securities of any series not previously delivered to the indenture trustee for cancellation when those debt securities:
 
  •  have become due and payable;
 
  •  will become due and payable at their stated maturity within one year; or
 
  •  are to be called for redemption within one year under arrangements satisfactory to the indenture trustee for giving notice of redemption.
 
NiSource Finance may terminate its obligations with respect to the debt securities of that series by depositing with the indenture trustee, as trust funds dedicated solely for that purpose, an amount sufficient to pay and discharge the entire indebtedness on the debt securities of that series. In that case, the Indenture will cease to be of further effect and NiSource Finance’s obligations will be satisfied and discharged with respect to that series (except as to NiSource Finance’s obligations to pay all other amounts due under the Indenture and to provide certain officers’ certificates and opinions of counsel to the indenture trustee). At the expense of NiSource Finance, the indenture trustee will execute proper instruments acknowledging the satisfaction and discharge. (See Section 401.)

Book-Entry Issuance
 
Unless otherwise specified in the applicable prospectus supplement, NiSource Finance will issue any debt securities offered under this prospectus as “global securities.” We will describe the specific terms for issuing any debt security as a global security in the prospectus supplement relating to that debt security.
 
Unless otherwise specified in the applicable prospectus supplement, The Depository Trust Company, or DTC, will act as the depositary for any global securities. NiSource Finance will issue global securities as fully registered securities registered in the name of DTC’s nominee, Cede & Co. NiSource Finance will issue one or more fully registered global securities for each issue of debt securities, each in the aggregate principal or stated amount of such issue, and will deposit the global securities with DTC.
 
DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered under the provisions of Section 17A of the Securities Exchange Act. DTC also facilitates the post-trade settlement among its direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between its direct participants’ accounts. This eliminates the need for physical movement of securities certificates. DTC’s direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation which, in turn, is owned by a number of DTC’s direct participants and members of the National Securities Clearing Corporation, Fixed Income Clearing Corporation and Emerging Markets Clearing Corporation, as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the Financial Industry Regulatory Authority. Access to the DTC system is also available to others such as U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. The DTC rules applicable to its participants are on file with the SEC.
 
Purchases of securities under DTC’s system must be made by or through a direct participant, which will receive a credit for such securities on DTC’s records. The ownership interest of each actual purchaser of each security, the beneficial owner, is in turn recorded on the records of direct and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchases, but they should receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the participants through which they entered into the transactions. Transfers of ownership interest in the securities are accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their securities, except in the event that use of the book-entry system for the securities is discontinued.
 
To facilitate subsequent transfers, all global securities that are deposited with, or on behalf of, DTC are registered in the name of DTC’s nominee, Cede & Co. The deposit of global securities with, or on behalf of, DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities; DTC’s records reflect only the identity of the direct participants to whose accounts such securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.
 
Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.
 
Neither DTC nor Cede & Co. will consent or vote with respect to the global securities. Under its usual procedures, DTC will mail an omnibus proxy to NiSource Finance as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the securities are credited on the applicable record date (identified in a listing attached to the omnibus proxy).
 
Redemption proceeds, principal payments and any premium, interest or other payments on the global securities will be made to Cede & Co., as nominee of DTC. DTC’s practice is to credit direct participants’


15


Table of Contents

accounts on the applicable payment date in accordance with their respective holdings shown on DTC’s records, unless DTC has reason to believe that it will not receive payment on that date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of the participant and not of DTC, NiSource Finance, NiSource or the indenture trustee, subject to any statutory or regulatory requirements in effect at the time. Payment of redemption payments, principal and any premium, interest or other payments to DTC is the responsibility of NiSource Finance and the applicable paying agent, disbursement of payments to direct participants will be the responsibility of DTC, and disbursement of payments to the beneficial owners will be the responsibility of direct and indirect participants.
 
If applicable, redemption notices will be sent to Cede & Co. If less than all of the debt securities of like tenor and terms are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.
 
A beneficial owner electing to have its interest in a global security repaid by NiSource Finance will give any required notice through its participant and will effect delivery of its interest by causing the direct participant to transfer the participant’s interest in the global securities on DTC’s records to the appropriate party. The requirement for physical delivery in connection with a demand for repayment will be deemed satisfied when the ownership rights in the global securities are transferred on DTC’s records.
 
DTC may discontinue providing its services as securities depositary with respect to the global securities at any time by giving reasonable notice to NiSource Finance or the indenture trustee. Under such circumstances, in the event that a successor securities depositary is not obtained, certificates for the securities are required to be printed and delivered.
 
NiSource Finance may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary). In that event, certificates for the securities will be printed and delivered.
 
We have provided the foregoing information with respect to DTC to the financial community for information purposes only. We do not intend the information to serve as a representation, warranty or contract modification of any kind. We have received the information in this section concerning DTC and DTC’s system from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information.
 
Governing Law
 
The Indenture and the debt securities are governed by the internal laws of the State of New York.
 
Information Concerning the Indenture Trustee
 
Prior to default, the indenture trustee will perform only those duties specifically set forth in the Indenture. After default, the indenture trustee will exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. The indenture trustee is under no obligation to exercise any of the powers vested in it by the Indenture at the request of any holder of debt securities unless the holder offers the indenture trustee reasonable indemnity against the costs, expenses and liability that the indenture trustee might incur in exercising those powers. The indenture trustee is not required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if it reasonably believes that it may not receive repayment or adequate indemnity. (See Section 601.)
 
DESCRIPTION OF WARRANTS
 
NiSource and NiSource Finance may issue warrants to purchase equity or debt securities, respectively. NiSource and NiSource Finance may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. NiSource and NiSource Finance will issue the warrants under warrant agreements to be entered into between NiSource or NiSource Finance, as the case may be, and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant


16


Table of Contents

agent will act solely as agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.
 
The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:
 
  •  the title of the warrants;
 
  •  the designation, amount and terms of the securities for which the warrants are exercisable;
 
  •  the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each other security;
 
  •  the price or prices at which the warrants will be issued;
 
  •  the aggregate number of warrants;
 
  •  any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;
 
  •  the price or prices at which the securities purchasable upon exercise of the warrants may be purchased;
 
  •  if applicable, the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable;
 
  •  if applicable, a discussion of the material U.S. federal income tax considerations applicable to the exercise of the warrants;
 
  •  any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants;
 
  •  the date on which the right to exercise the warrants will commence, and the date on which the right will expire;
 
  •  the maximum or minimum number of warrants that may be exercised at any time; and
 
  •  information with respect to book-entry procedures, if any.
 
Exercise of Warrants
 
Each warrant will entitle the holder of warrants to purchase for cash the amount of equity or debt securities at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, NiSource or NiSource Finance, as the case may be, will, as soon as possible, forward the equity or debt securities that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, NiSource or NiSource Finance, as the case may be, will issue a new warrant certificate for the remaining warrants.
 
DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
NiSource may issue stock purchase contracts, including contracts obligating holders to purchase from NiSource, and for NiSource to sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock and the number of shares of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula stated in the stock purchase contracts.


17


Table of Contents

The stock purchase contracts may be issued separately or as part of units that we call “stock purchase units.” Stock purchase units consist of a stock purchase contract and either NiSource Finance’s debt securities or U.S. treasury securities securing the holders’ obligations to purchase the common stock under the stock purchase contracts.
 
The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa, and these payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner.

PLAN OF DISTRIBUTION
 
We may sell the securities to or through underwriters, through dealers or agents, directly to you or through a combination of these methods. The prospectus supplement with respect to any offering of securities will describe the specific terms of the securities being offered, including:
 
  •  the name or names of any underwriters, dealers or agents;
 
  •  the purchase price of the securities and the proceeds to NiSource or NiSource Finance from the sale;
 
  •  any underwriting discounts and commissions or agency fees and other items constituting underwriters’ or agents’ compensation;
 
  •  any initial public offering price;
 
  •  any discounts or concessions allowed or reallowed or paid to dealers; and
 
  •  any securities exchange on which the offered securities may be listed.
 
Through Underwriters.  If we use underwriters in the sale of the securities, the underwriters will acquire the offered securities for their own account. We will execute an underwriting agreement with an underwriter or underwriters once an agreement for sale of the securities is reached. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The underwriters may sell the offered securities directly or through underwriting syndicates represented by managing underwriters. Unless otherwise stated in the prospectus supplement relating to offered securities, the obligations of the underwriters to purchase those offered securities will be subject to certain conditions, and the underwriters will be obligated to purchase all of those offered securities if they purchase any of them.
 
Through Dealers.  If we use a dealer to sell the securities, we will sell the offered securities to the dealer as principal. The dealer may then resell those offered securities at varying prices determined at the time of resale. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.
 
Through Agents.  If we use agents in the sale of securities, we may designate one or more agents to sell offered securities. Unless otherwise stated in a prospectus supplement, the agents will agree to use their best efforts to solicit purchases for the period of their appointment.
 
Directly to Purchasers.  We may sell the offered securities directly to one or more purchasers. In this case, no underwriters, dealers or agents would be involved. We will describe the terms of our direct sales in our prospectus supplement.
 
General Information.  A prospectus supplement will state the name of any underwriter, dealer or agent and the amount of any compensation, underwriting discounts or concessions paid, allowed or reallowed to them. A
