NiSource Inc.

Common Stock

We may issue, offer and sell up to an aggregate of $500,000,000 of our common stock from time to time through MUFG Securities Americas Inc. (“MUFG”), BNP Paribas Securities Corp. (“BNP Paribas”), Citigroup Global Markets Inc. (“Citigroup”), Goldman Sachs & Co. LLC (“Goldman Sachs”) and RBC Capital Markets, LLC (“RBC”), as our agents under separate equity distribution agreements. We refer to MUFG, BNP Paribas, Citigroup, Goldman Sachs and RBC collectively as the sales agents. Each equity distribution agreement provides that, in addition to the issuance and sale of common stock by us through the applicable sales agent, we also may enter into forward sale agreements under a separate master forward sale confirmation and related supplemental confirmation between us and such sales agent or its affiliate. We refer to these entities, when acting in such capacity, as forward purchasers. In connection with each forward sale agreement, the relevant forward purchaser will, at our request, attempt to borrow from third parties and, through the relevant sales agent, sell a number of shares of our common stock equal to the number of shares of our common stock that underlie the forward sale agreement to hedge the forward sale agreement. We refer to each of the sales agents, when acting as the agent for a forward purchaser, as a forward seller. In no event will the aggregate number of shares of our common stock sold through the sales agents, as our agents and as forward sellers, under the equity distribution agreements have an aggregate sales price in excess of $500,000,000. The offering of our common stock pursuant to the equity distribution agreements will terminate upon the earliest of (1) the sale, under the equity distribution agreements, of shares of our common stock with an aggregate sales price of $500,000,000, (2) December 31, 2020 (provided that each relevant equity distribution agreement will continue in effect for the duration of, and solely with respect to, any forward stock purchase transaction entered into, but not yet settled, before December 31, 2020) and (3) termination by us or the relevant sales agent any time upon two days’ notice.

We will not initially receive any proceeds from the sale of borrowed shares of our common stock by a forward seller. We expect to receive proceeds from the sale of shares of our common stock upon future physical settlement of the relevant forward sale agreement with the relevant forward purchaser on dates specified by us on or prior to the maturity date of the relevant forward sale agreement. If we elect to cash settle or net share settle a forward sale agreement, we may not (in the case of cash settlement) or will not (in the case of net share settlement) receive any proceeds, and we may owe cash (in the case of cash settlement) or shares of our common stock (in the case of net share settlement) to the relevant forward purchaser.

The shares of our common stock will be offered at market prices prevailing at the time of sale. We will pay each sales agent a commission of up to 2% of the sales price of all shares of our common stock sold through it as our sales agent under the applicable equity distribution agreement. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory or self-regulatory organization in connection with the sales, will be our net proceeds for the sale of the shares. In connection with each forward sale agreement, the relevant forward seller will receive, reflected in a reduced initial forward sale price payable by the relevant forward purchaser under its forward sale agreement, a commission of up to 2% of the volume weighted average of the sales prices of all borrowed shares of our common stock sold during the applicable period by it as a forward seller.

Our common stock is listed on the New York Stock Exchange under the symbol “NI.” The last reported sale price of our common stock on the New York Stock Exchange on October 31, 2018 was $25.36 per share.

Investing in our common stock involves risks. For a discussion of these risks, please refer to “Risk Factors” beginning on page S-4 of this prospectus supplement and “Risk Factors” beginning on page 9 of our Annual Report on Form 10-K for the year ended December 31, 2017.

Neither the Securities and Exchange Commission, or SEC, nor any other regulatory body has approved or disapproved of the common stock or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

You should read carefully the “Risk Factors” section on page S-4 of this prospectus supplement and the “Risk Factors” and “Note Regarding Forward-Looking Statements” sections in our Annual Report on Form 10-K for the year ended December 31, 2017 for more information about important risks that you should consider before investing in our common stock.

NISOURCE INC.

Overview. NiSource is an energy holding company whose subsidiaries are fully regulated natural gas and electric utility companies serving approximately 3.9 million customers in seven states. We are one of the nation’s largest natural gas distribution companies, as measured by number of customers. Our principal subsidiaries include NiSource Gas Distribution Group, Inc., a natural gas distribution company, and Northern Indiana Public Service Company LLC, or NIPSCO, a gas and electric company. NiSource derives substantially all of its revenues and earnings from the operating results of these rate-regulated businesses. Our primary business segments are:

•

Gas Distribution Operations; and

•

Electric Operations.

On July 1, 2015, we completed the spin-off of our former subsidiary Columbia Pipeline Group, Inc., which comprised all of our Columbia Pipeline Group Operations segment prior to that time.

Business Strategy. We focus our business strategy on our core, rate-regulated asset-based businesses with most of our operating income generated from the rate-regulated businesses. NiSource’s utilities continue to move forward on core infrastructure and environmental investment programs supported by complementary regulatory and customer initiatives across all seven states in which we operate. Our goal is to develop strategies that benefit all stakeholders as we address changing customer conservation patterns, develop more contemporary pricing structures and embark on long-term investment programs. These strategies will help improve reliability and safety, enhance customer services and reduce emissions while generating sustainable returns.

Gas Distribution Operations. Our natural gas distribution operations serve approximately 3.5 million customers in seven states and operate approximately 60,000 miles of pipeline. Through our wholly-owned subsidiary NiSource Gas Distribution Group, Inc., we own six distribution subsidiaries that provide natural gas to approximately 2.6 million residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland and Massachusetts. We also distribute natural gas to approximately 830,000 customers in northern Indiana through our wholly-owned subsidiary NIPSCO.

Electric Operations. We generate, transmit and distribute electricity through our subsidiary NIPSCO to approximately 469,000 customers in 20 counties in the northern part of Indiana and engage in wholesale and transmission transactions. NIPSCO owns and operates two coal-fired electric generating stations. The two operating facilities have a net capability of 2,094 megawatts. NIPSCO completed the retirement of the coal-fired

S-1

generating units at its Bailly Generating Station on May 31, 2018. NIPSCO also owns and operates Sugar Creek, a combined cycle gas turbine plant with a net capability of 535 megawatts, three gas-fired generating units located at NIPSCO’s coal-fired electric generating stations with a net capability of 196 megawatts and two hydroelectric generating plants with a net capability of 10 megawatts. These facilities provide for a total system operating net capability of 2,835 megawatts. NIPSCO’s transmission system, with voltages from 69,000 to 345,000 volts, consists of 2,843 circuit miles. NIPSCO is interconnected with five neighboring electric utilities. During the year ended December 31, 2017, NIPSCO generated 65.2% and purchased 34.8% of its electric requirements.

Our executive offices are located at 801 East 86th Avenue, Merrillville, Indiana 46410, telephone: (877) 647-5990.

THE OFFERING

Issuer

NiSource Inc., a Delaware corporation.

Common Stock Offered

Shares of common stock, $.01 par value, having an aggregate sales price of up to $500,000,000.

Use of Proceeds

We intend to use the net proceeds we receive upon the issuance and sale of shares of our common stock to finance capital expenditures and for general corporate purposes.

We will not initially receive any proceeds from the sale of borrowed shares of our common stock by the forward sellers in connection with any forward sale agreement as a hedge of the forward sale agreement. We intend to use any cash proceeds that we receive upon physical settlement of any forward sale agreement, if physical settlement applies, or upon cash settlement of any forward sale agreement, if we elect cash settlement, to finance capital expenditures and for general corporate purposes. See “Use of Proceeds.”

Conflicts of Interest

The forward purchasers will receive the net proceeds of any sale of borrowed shares of our common stock pursuant to this prospectus supplement in connection with any forward sale agreement. Because certain sales agents or their affiliates are expected to receive part of the net proceeds from the sale of shares of our common stock in connection with any forward sale agreement, such sales agents would be deemed to have a conflict of interest under Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121 to the extent such sales agents or affiliates receive at least 5% of the net proceeds of the offering. Any sales agent deemed to have a conflict of interest would be required to conduct the distribution of our common stock in accordance with FINRA Rule 5121. If the offering is conducted in accordance with FINRA Rule 5121, such sales agent would not be permitted to confirm a sale to an account over which it exercises discretionary authority without first receiving specific written approval from the account holder.

Risk Factors

An investment in our common stock involves various risks, and prospective investors should carefully consider the matters discussed under the caption entitled “Risk Factors” beginning on page S-4 of this prospectus supplement and under the caption entitled “Risk Factors” beginning on page 9 of the Annual Report on Form 10-K for the year ended December 31, 2017.

RISK FACTORS

Investing in our common stock involves risks. You should carefully review the information contained elsewhere or incorporated by reference in this prospectus supplement and the accompanying prospectus and should carefully consider the following risk factors, as well as the “Risk Factors” section in the accompanying prospectus on page 2, in our Annual Report on Form 10-K for the year ended December 31, 2017 under the title “Item 1A. Risk Factors” and in any subsequent periodic reports that are incorporated by reference into this prospectus supplement and the accompanying prospectus. Each of the risks described could materially adversely affect our operations and financial results and the value of your investment in our common stock.

Settlement provisions contained in a forward sale agreement could result in substantial dilution to our earnings per share and return on equity or result in substantial cash payment obligations.

If we enter into one or more forward sale agreements, the relevant forward purchaser will have the right to accelerate that particular forward sale agreement (with respect to a transaction under that particular forward sale agreement that the relevant forward purchaser determines is affected by such event) and require us to physically settle or, if we so elect and the forward purchaser permits our election, cash settle or net share settle on a date specified by the relevant forward purchaser if:

•

the relevant forward purchaser is unable to, or would incur a materially increased cost to, establish, maintain or unwind its hedge position with respect to that particular forward sale agreement;

•

the relevant forward purchaser determines that it is unable, after using commercially reasonable efforts, to continue to borrow a number of shares of our common stock equal to the number of shares of our common stock underlying that particular forward sale agreement or that, with respect to borrowing such number of shares of our common stock, it would incur a cost that is greater than the stock borrow cost specified in that particular forward sale agreement;

•

a termination event occurs as a result of us declaring a dividend or distribution on our common stock (i) with a cash value in excess of a specified amount per calendar quarter, (ii) with an ex-dividend date prior to the anticipated ex-dividend date for such cash dividend or (iii) payable in securities of another company as a result of a spin-off or similar transaction or in any other type of securities (other than our common stock), rights, warrants or other assets for payment at less than the prevailing market price;

•

certain ownership thresholds applicable to such forward purchaser, its affiliates and all other persons who may form a beneficial share ownership group or whose ownership positions would be aggregated with such forward purchaser are exceeded;

•

the announcement of an event or a transaction that, if consummated, would result in an extraordinary event (as such term is defined in that particular forward sale agreement and which includes certain mergers and tender offers as well as certain events involving our nationalization or the delisting of our common stock); or

•

certain other events of default, termination events or other specified events occur, including, among other things, any material misrepresentation made by us in connection with entering into that particular forward sale agreement, our bankruptcy or a change in law (as such terms are defined in that particular forward sale agreement).

A forward purchaser’s decision to exercise its right to accelerate the settlement of a particular forward sale agreement will be made irrespective of our need for capital. In such cases, we could be required to issue and deliver shares of common stock under the physical settlement provisions of that particular forward sale agreement or, if we so elect and the forward purchaser permits our election, the net share settlement provisions of that particular forward sale agreement irrespective of our capital needs, which would result in dilution to our earnings per share and return on equity.

S-4

We expect that settlement of any forward sale agreement will generally occur no later than the date specified in the particular forward sale agreement. However, any forward sale agreement may be settled earlier than that specified date in whole or in part at our option. We expect that each forward sale agreement will be physically settled by delivery of shares of our common stock, unless we elect to cash settle or net share settle a particular forward sale agreement. Upon physical settlement or, if we so elect, net share settlement of a particular forward sale agreement, delivery of shares of our common stock in connection with such physical settlement or (to the extent we are obligated to deliver shares of our common stock) net share settlement will result in dilution to our earnings per share and return on equity. If we elect cash settlement or net share settlement with respect to all or a portion of the shares of common stock underlying a particular forward sale agreement, we expect that the relevant forward purchaser (or an affiliate thereof) will purchase a number of shares of common stock necessary to satisfy its or its affiliate’s obligation to return the shares of common stock borrowed from third parties in connection with sales of shares of our common stock under that forward sale agreement. In addition, the purchase of shares of our common stock in connection with the relevant forward purchaser or its affiliate unwinding its hedge positions could cause the price of our common stock to increase over such time (or prevent a decrease over such time), thereby increasing the amount of cash we would owe to the relevant forward purchaser (or decreasing the amount of cash that the relevant forward purchaser would owe us) upon a cash settlement of the relevant forward sale agreement or increasing the number of shares of common stock we would deliver to the relevant forward purchaser (or decreasing the number of shares of common stock that the relevant forward purchaser would deliver to us) upon net share settlement of the relevant forward sale agreement. In no event will we be party to outstanding forward sale agreements with more than one forward purchaser at any given time or party to more than one forward sale agreement with the same forward purchaser at any given time unless the related forward sellers would not be selling shares of our common stock simultaneously and the related forward purchasers would not be required to unwind their respective hedges of shares of our common stock either simultaneously or at any time that the related forward sellers are selling shares of our common stock. Additionally, in no event may we sell shares directly at any given time when we are a party to outstanding forward sale agreements unless the related forward sellers would not then be selling shares of our common stock and the related forward purchasers would not then be required to unwind their respective hedges of shares of our common stock.

The forward sale price that we expect to receive upon physical settlement of a particular forward sale agreement will be subject to adjustment on a daily basis based on a floating interest rate factor equal to the overnight bank funding rate less a spread and will be decreased based on amounts related to expected dividends on our common stock during the term of the particular forward sale agreement. If the overnight bank funding rate is less than the spread for a particular forward sale agreement on any day, the interest factor will result in a reduction of the applicable forward sale price for such day. As of the date of this prospectus supplement, the overnight bank funding rate is less than the expected spread. If the market value of our common stock during the relevant valuation period under the particular forward sale agreement is above the applicable forward sale price, in the case of cash settlement, we would pay the relevant forward purchaser under that particular forward sale agreement an amount in cash equal to the difference or, in the case of net share settlement, we would deliver to the relevant forward purchaser a number of shares of common stock having a value equal to the difference. Thus, we could be responsible for a potentially substantial cash payment in the case of cash settlement of a particular forward sale agreement. See “Plan of Distribution (Conflicts of Interest) – Sales Through Forward Sellers” for information on the forward sale agreements.

In case of our bankruptcy or insolvency, any forward sale agreements will automatically terminate, and we would not receive the expected proceeds from any forward sales of our common stock.

If we file for or consent to a proceeding seeking a judgment in bankruptcy or insolvency or any other relief under any bankruptcy or insolvency law or other similar law affecting creditors’ rights, or we or a regulatory authority with jurisdiction over us presents a petition for our winding-up or liquidation, and we consent to such a petition, any forward sale agreements that are then in effect will automatically terminate. If any such forward sale agreement so terminates under these circumstances, we would not be obligated to deliver to the

S-5

relevant forward purchaser any of our common stock not previously delivered, and the relevant forward purchaser would be discharged from its obligation to pay the applicable forward sale price per share in respect of any of our common stock not previously settled under the applicable forward sale agreement. Therefore, to the extent that there are any shares of our common stock with respect to which any forward sale agreement has not been settled at the time of the commencement of any such bankruptcy or insolvency proceedings, we would not receive the relevant forward sale price per share in respect of those shares of our common stock.

S-6

USE OF PROCEEDS

We intend to use the net proceeds that we receive upon the issuance and sale of shares of our common stock by us through the sales agents to finance capital expenditures and for general corporate purposes.

We will not initially receive any proceeds from the sale of borrowed shares of our common stock by the forward sellers, as agents for the forward purchasers, in connection with any forward sale agreement as a hedge of the forward sale agreement. In the event of full physical settlement of a forward sale agreement, which we expect to occur on or prior to the maturity date of the forward sale agreement, we expect to receive aggregate cash proceeds equal to the product of the initial forward sale price under the forward sale agreement and the number of shares of our common stock underlying the forward sale agreement, subject to the price adjustment and other provisions of the forward sale agreement. We intend to use any cash proceeds that we receive upon physical settlement of any forward sale agreement, if physical settlement applies, or upon cash settlement of any forward sale agreement, if we elect cash settlement, for the purposes provided in the immediately preceding paragraph. If, however, we elect to cash settle or net share settle any forward sale agreement, we would expect to receive an amount of proceeds that is significantly lower than the product set forth in the second preceding sentence (in the case of any cash settlement) or will not receive any proceeds (in the case of any net share settlement), and we may owe cash (in the case of any cash settlement) or shares of our common stock (in the case of any net share settlement) to the forward purchaser.

S-7

On October 31, 2018, the last reported sale price of our common stock on the New York Stock Exchange was $25.36 per share. As of October 25, 2018, there were 363,288,024 shares of our common stock outstanding.

Holders of shares of our common stock are entitled to receive dividends when, as and if declared by NiSource’s board of directors out of funds legally available. The policy of our board of directors has been to declare cash dividends on a quarterly basis payable on or about the 20th day of February, May, August and November.

Although the board of directors currently intends to continue the payment of regular quarterly cash dividends on common shares, the timing and amount of future dividends will depend on the earnings of NiSource’s subsidiaries, their financial condition, cash requirements, regulatory restrictions, any restrictions in financing agreements and other factors deemed relevant by the board.

S-8

PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have entered into separate equity distribution agreements with each of the sales agents and forward purchasers. Under the terms of each equity distribution agreement we may issue and sell from time to time shares of our common stock having an aggregate sales price of up to $500,000,000 through the sales agents acting as our agents. Further, each equity distribution agreement provides that, in addition to the issuance and sale of shares of our common stock by us through the applicable sales agent, we may request that such sales agent, as a forward seller, use commercially reasonable efforts to sell, from time to time, shares of our common stock borrowed by the applicable forward purchaser in connection with one or more forward sale agreements as described below. In no event will the aggregate number of shares of our common stock sold through the sales agents, each as an agent for us and as a forward seller, under the equity distribution agreements have an aggregate sales price in excess of $500,000,000.

Sales of the shares of our common stock, if any, under any equity distribution agreement will be made in “at the market offerings” as defined in Rule 415 of the Securities Act, including sales made directly on the New York Stock Exchange, the existing trading market for shares of our common stock, or sales made to or through a market maker or through an electronic communications network. In addition, shares of our common stock may be offered and sold by such other methods, including privately negotiated transactions, as we and any sales agent (and any related forward seller and forward purchaser) agree to in writing. The sales agents will not engage in any transactions that stabilize our common stock.

We have agreed to pay all expenses in connection with the equity distribution agreements, the forward sale agreements and the offerings hereby, including the reasonable fees and disbursements of Hunton Andrews Kurth LLP, in connection with the initial documentation of the offerings contemplated by this prospectus supplement. We estimate that the total expenses for the offering, excluding compensation payable under the equity distribution agreements, will be approximately $400,000.

In connection with the sale of our common stock as contemplated in this prospectus supplement, the sales agents, forward purchasers and/or forward sellers each may be deemed to be “underwriters” within the meaning of the Securities Act, and the compensation paid to a sales agent in the form of a reduced initial forward sale price under a forward sale agreement with the related forward purchaser may be deemed to be underwriting commissions or discounts. We have agreed to indemnify the sales agents, the forward sellers and the forward purchasers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments which they may be required to make in that respect.

We intend to report to the SEC at least quarterly (1) the number of shares of our common stock sold through the sales agents in connection with at-the-market sales as described below under “—Sales Through Sales Agents,” (2) the number of borrowed shares of our common stock sold by the forward sellers, as agents for the forward purchasers, in connection with forward sale agreements as described below under “—Sales Through Forward Sellers” and (3) the net proceeds received by us and the compensation paid by us to the sales agents in connection with transactions described in clauses (1) and (2).

Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and the sales agents may agree upon. The offering of our common stock pursuant to the equity distribution agreements will terminate upon the earliest of (1) the sale, under the equity distribution agreements, of shares of our common stock with an aggregate sales price of $500,000,000, (2) December 31, 2020 (provided that each relevant equity distribution agreement will continue in effect for the duration of, and solely with respect to, any forward stock purchase transaction entered into, but not yet settled, before December 31, 2020) and (3) termination by us or the relevant sales agent any time upon two days’ notice.

S-9

Sales Through Sales Agents

From time to time during the term of the equity distribution agreements, and subject to the terms and conditions set forth therein, we may deliver instructions to any of the sales agents regarding a proposed sale of shares of our common stock. Upon receipt of instructions from us, and subject to the terms and conditions of the applicable equity distribution agreement, each sales agent will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell the amount of shares of our common stock specified in our instructions. We or the relevant sales agent may suspend the offering of shares of our common stock at any time upon proper notice to the other, upon which the selling period will immediately terminate. Settlement for sales of shares of our common stock will occur on the second trading day following the date on which the sales were made, or such earlier day as required by SEC rule or industry practice, unless another date shall be agreed to in writing by us and the relevant sales agent. The obligation of each sales agent under the applicable equity distribution agreement to sell shares of our common stock pursuant to our instructions is subject to a number of conditions, which each sales agent reserves the right to waive in its sole discretion.

Each sales agent will receive from us a commission of up to 2% of the gross sales price per share for any shares sold through it as our sales agent under the applicable equity distribution agreement. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory or self-regulatory organization in connection with the sales, will be our net proceeds for the sale of such shares.

Sales Through Forward Sellers

From time to time during the term of the equity distribution agreements, and subject to the terms and conditions set forth therein, we may enter into one or more forward sale agreements with a sales agent or its affiliate, as forward purchaser, and deliver to it a related transaction confirmation under its equity distribution agreement in its capacity as forward seller thereunder. Upon receipt and acceptance by a forward seller and the applicable forward purchaser of a transaction confirmation from us requesting that it execute sales of borrowed shares of common stock as a forward seller in connection with the applicable forward sale agreement and subject to the terms and conditions of the relevant equity distribution agreement, the relevant forward purchaser will attempt to borrow, and the relevant forward seller will use commercially reasonable efforts consistent with its normal trading and sales practices to sell, the relevant shares of our common stock to hedge the relevant forward purchaser’s exposure under that particular forward sale agreement. We or the relevant forward seller may immediately suspend the offering of our common stock at any time upon proper notice to the other. In no event will we be party to outstanding forward sale agreements with more than one forward purchaser at any given time or party to more than one forward sale agreement with the same forward purchaser at any given time unless the related forward sellers would not be selling shares of our common stock simultaneously and the related forward purchasers would not be required to unwind their respective hedges of shares of our common stock either simultaneously or at any time that the related forward sellers are selling shares of our common stock. Additionally, in no event may we sell shares directly at any given time when we are a party to outstanding forward sale agreements unless the related forward sellers would not then be selling shares of our common stock and the related forward purchasers would not then be required to unwind their respective hedges of shares of our common stock.

We expect that settlement between the relevant forward purchaser and forward seller of sales of borrowed shares of our common stock, as well as the settlement between the relevant forward seller and buyers of such shares of our common stock in the market, will generally occur on the second trading day following each date the sales are made or such earlier day as required by SEC rule or industry practice, unless another date shall be agreed to in writing by us and the relevant forward seller. The obligation of the relevant forward seller under the relevant equity distribution agreement to execute such sales of our common stock is subject to a number of conditions, which each forward seller reserves the right to waive in its sole discretion.

S-10

In connection with each forward sale agreement, we will pay the relevant forward seller, in the form of a reduced initial forward sale price payable by the relevant forward purchaser under the related forward sale agreement, commissions of up to 2% of the sales prices of all borrowed shares of common stock sold during the applicable forward hedge selling period by it as a forward seller. We refer to this commission rate as the forward selling commission. The forward hedge selling period will be the period of one to 20 consecutive trading days determined by us in our sole discretion and as specified in the relevant transaction confirmation and the forward sale agreement related thereto.

The forward sale price per share under each forward sale agreement will initially equal the product of (1) an amount equal to one minus the applicable forward selling commission and (2) the volume-weighted average price per share at which the borrowed shares of common stock were sold pursuant to the particular equity distribution agreement by the relevant forward seller. Thereafter, the forward sale price will be subject to adjustment as described below.

The forward sale agreements will provide that the forward sale price, as well as the sales prices used to calculate the initial forward sale price, will be subject to increase or decrease based on a floating interest rate factor equal to the overnight bank funding rate less a spread and subject to decrease by amounts related to expected dividends on our common stock during the term of the particular forward sale agreement. If the overnight bank funding rate is less than the spread for a particular forward sale agreement on any day, the interest factor will result in a reduction of the applicable forward sale price for such day. As of the date of this prospectus supplement, the overnight bank funding rate is less than the expected spread. Unless the overnight bank funding rate increases substantially prior to the settlement of any particular forward sale agreement, we would expect to receive less than the initial forward sale price per share upon physical settlement of that particular forward sale agreement.

Before settlement of a particular forward sale agreement, we expect that the shares of our common stock issuable upon settlement of that particular forward sale agreement will be reflected in our diluted earnings per share, return on equity and dividends per share calculations using the treasury stock method. Under this method, the number of shares of our common stock used in calculating diluted earnings per share, return on equity and dividends per share is deemed to be increased by the excess, if any, of the number of shares of our common stock that would be issued upon full physical settlement of that particular forward sale agreement over the number of shares of our common stock that could be purchased by us in the market (based on the average market price during the relevant period) using the proceeds receivable upon full physical settlement (based on the adjusted forward sale price at the end of the relevant reporting period). Consequently, before physical or net share settlement of a particular forward sale agreement and subject to the occurrence of certain events, we anticipate there will be no dilutive effect on our earnings per share, except during periods when the average market price of our common stock is above the applicable forward sale price.

Except under limited circumstances described below, we have the right to elect physical, cash or net share settlement under any forward sale agreement. Although we expect to settle any forward sale agreement entirely by delivering shares of our common stock in connection with full physical settlement, we may, subject to certain conditions, elect cash settlement or net share settlement for all or a portion of our obligations under a particular forward sale agreement if we conclude that it is in our interest to do so. For example, we may conclude that it is in our interest to cash settle or net share settle a particular forward sale agreement if we have no then-current use for all or a portion of the net proceeds that we would receive upon physical settlement. In addition, subject to certain conditions, we may elect to accelerate the settlement of all or a portion of the number of shares of our common stock underlying a particular forward sale agreement.

If we elect to physically settle any forward sale agreement by issuing and delivering shares of our common stock, we will receive an amount of cash from the relevant forward purchaser equal to the product of the forward sale price per share under that particular forward sale agreement and the number of shares of our common stock underlying the particular forward sale agreement. In the event that we elect to cash settle, the

S-11

settlement amount will be generally related to (1) (a) the average of the volume-weighted average price of our common stock on each exchange business day during the relevant valuation period under the particular forward sale agreement minus (b) the applicable forward sale price; multiplied by (2) the number of shares of our common stock underlying the particular forward sale agreement subject to cash settlement. In the event we elect to net share settle, the settlement amount will be generally related to (1) (a) the weighted average price at which the relevant forward purchaser or its affiliate purchases shares of our common stock during the relevant valuation period for such settlement under that particular forward sale agreement minus (b) the applicable forward sale price; multiplied by (2) the number of shares of our common stock underlying the particular forward sale agreement subject to such net share settlement. If this settlement amount is a negative number, the relevant forward purchaser will pay us the absolute value of that amount (in the case of cash settlement) or deliver to us a number of shares of our common stock having a value equal to the absolute value of such amount (in the event of net share settlement). If this settlement amount is a positive number, we will pay the relevant forward purchaser that amount (in the case of cash settlement) or deliver to the relevant forward purchaser a number of shares of our common stock having a value equal to such amount (in the event of net share settlement). In connection with any cash settlement or net share settlement, we would expect the relevant forward purchaser or its affiliate to purchase shares of our common stock in secondary market transactions for delivery to third-party stock lenders in order to close out its, or its affiliate’s, hedge position in respect of that particular forward sale agreement. The purchase of shares of our common stock in connection with the relevant forward purchaser or its affiliate unwinding its hedge positions could cause the price of our common stock to increase over time (or prevent a decrease over time), thereby increasing the amount of cash we owe to the relevant forward purchaser (or decreasing the amount of cash that the relevant forward purchaser owes us) upon cash settlement or increasing the number of shares of our common stock that we are obligated to deliver to the relevant forward purchaser (or decreasing the number of shares of our common stock that the relevant forward purchaser is obligated to deliver to us) upon net share settlement of the particular forward sale agreement. See “Risk Factors.”

A forward purchaser will have the right to accelerate its forward sale agreement (with respect to a transaction under the particular forward sale agreement that the relevant forward purchaser determines is affected by such event) and require us to physically settle or, if we so elect and the forward purchaser permits our election, cash settle or net share settle on a date specified by the relevant forward purchaser if:

•

the relevant forward purchaser is unable to, or would incur a materially increased cost to, establish, maintain or unwind its hedge position with respect to that particular forward sale agreement;

•

S-12

forward sale agreement, our bankruptcy or a change in law (as such terms are defined in that particular forward sale agreement).

The relevant forward purchaser’s decision to exercise its right to accelerate the settlement of the particular forward sale agreement will be made irrespective of our need for capital. In such cases, we could be required to issue and deliver shares of our common stock under the physical settlement provisions of the particular forward sale agreement or, if we so elect and the relevant forward purchaser so permits our election, the net share settlement provisions of the particular forward sale agreement irrespective of our capital needs, which would result in dilution to our earnings per share, return on equity and dividends per share. In addition, upon certain events of bankruptcy, insolvency or reorganization relating to us, the particular forward sale agreement will terminate without further liability of either party. Following any such termination, we would not issue any shares of our common stock or receive any proceeds pursuant to the particular forward sale agreement. See “Risk Factors.”

Restrictions on Sales of Similar Securities

We have agreed that, unless we give the sales agents at least three business days’ prior written notice, we will not directly or indirectly sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to sell or otherwise dispose of or agree to dispose of any shares of our common stock or any securities convertible into or exchangeable or exercisable for our common stock or warrants or other rights to purchase our common stock or any of our other securities that are substantially similar to our common stock or permit the registration under the Securities Act, of any shares of our common stock, except for:

•

any shares of our common stock we offer or sell pursuant to the equity distribution agreements (including sales of borrowed shares of our common stock by the forward sellers in connection with any forward sale agreement);

•

any shares of our common stock we issue upon physical settlement or net share settlement of any forward sale agreement;

•

any shares of our common stock we issue upon the exercise of an option or warrant or the conversion of a security outstanding on the date of the equity distribution agreements;

•

any shares of our common stock or stock units issued or options to purchase our common stock granted pursuant to our existing employee benefit plans, including shares of our common stock issued upon exercise of such options; or

•

any shares of our common stock or stock units issued pursuant to any of our non-employee director stock plan, dividend reinvestment plan or stock purchase plan.

No Public Offering Outside of the United States

No action has been or will be taken in any jurisdiction (except in the United States) that would permit a public offering of the shares of our common stock, or the possession, circulation or distribution of this prospectus supplement or the accompanying prospectus or any other material relating to us or the shares of our common stock, in any jurisdiction where action for that purpose is required. Accordingly, the shares of our common stock offered by this prospectus supplement and the accompanying prospectus may not be offered or sold, directly or indirectly, and this prospectus supplement, the accompanying prospectus and any other offering material or advertisements in connection with the shares of our common stock may not be distributed or published, in or from any country or jurisdiction except in compliance with any applicable rules and regulations of any such country or jurisdiction.

Conflicts of Interest

S-13

agents or their affiliates are expected to receive part of the net proceeds from the sale of shares of our common stock in connection with any forward sale agreement, such sales agents would be deemed to have a conflict of interest under FINRA Rule 5121 to the extent such sales agents or affiliates receive at least 5% of the net proceeds of the offering. Any sales agent deemed to have a conflict of interest would be required to conduct the distribution of our common stock in accordance with FINRA Rule 5121. If the offering is conducted in accordance with FINRA Rule 5121, such sales agent would not be permitted to confirm a sale to an account over which it exercises discretionary authority without first receiving specific written approval from the account holder.

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, 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.

Factors that could cause actual results to differ materially from the forward-looking statements include, among other things, NiSource’s debt obligations; any changes in NiSource’s credit rating; NiSource’s ability to execute its growth strategy; changes in general economic, capital and commodity market conditions; pension funding obligations; economic regulation and the impact of regulatory rate reviews; NiSource’s ability to obtain expected financial or regulatory outcomes; any damage to NiSource’s reputation; compliance with environmental laws and the costs of associated liabilities; fluctuations in demand from residential and commercial customers; economic conditions of certain industries; the success of NIPSCO’s electric generation strategy; the price of energy commodities and related transportation costs; the reliability of customers and suppliers to fulfill their payment and contractual obligations; potential impairments of goodwill or definite-lived intangible assets; changes in taxation and accounting principles; potential incidents and other operating risks associated with our business; the impact of an aging infrastructure; the impact of climate change; potential cyber-attacks; construction risks and natural gas costs and supply risks; extreme weather conditions; the attraction and retention of a qualified workforce; advances in technology; the ability of NiSource’s subsidiaries to generate cash; tax liabilities associated with the separation of Columbia Pipeline Group, Inc. on July 1, 2015, and other matters set forth in the “Risk Factors” section of NiSource’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and NiSource’s Quarterly Reports on Forms 10-Q for quarterly periods ended in 2017, many of which risks are beyond the control of NiSource. In addition, the relative contributions to profitability by each business segment, and the assumptions underlying the forward-looking statements relating thereto, may change over time. All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements. NiSource undertakes no obligation, and expressly disclaims any such obligation, to update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events or changes to the future results over time or otherwise, except as required by law.

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.

NISOURCE INC.

Overview. NiSource is an energy holding company whose subsidiaries are fully regulated natural gas and electric utility companies serving approximately 3.9 million customers in seven states. We are one of the nation’s largest natural gas distribution companies, as measured by number of customers. Our principal subsidiaries include NiSource Gas Distribution Group, Inc., a natural gas distribution company, and Northern Indiana Public Service Company, or NIPSCO, a vertically-integrated natural gas and electric company. NiSource derives substantially all of its revenues and earnings from the operating results of these rate-regulated businesses. Our primary business segments are:

•

Gas Distribution Operations; and

•

Electric Operations.

On July 1, 2015, we completed the spin-off of our former subsidiary Columbia Pipeline Group, Inc., which comprised all of our Columbia Pipeline Group Operations segment prior to that time.

Gas Distribution Operations. Our natural gas distribution operations serve approximately 3.4 million customers in seven states and operate approximately 59,000 miles of pipeline. Through our wholly-owned subsidiary NiSource Gas Distribution Group, Inc., we own six distribution subsidiaries that provide natural gas to approximately 2.6 million residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland and Massachusetts. We also distribute natural gas to approximately 820,000 customers in northern Indiana through our wholly-owned subsidiary NIPSCO.

Electric Operations. We generate, transmit and distribute electricity through our subsidiary NIPSCO to approximately 466,000 customers in 20 counties in the northern part of Indiana and engage in wholesale and transmission transactions. NIPSCO owns and operates three coal-fired electric generating stations. The three operating facilities have a net capability of 2,540 megawatts. NIPSCO also owns and operates Sugar Creek, a combined cycle gas turbine plant with a net capability of 535 megawatts, three gas-fired generating units located at NIPSCO’s coal-fired electric generating stations with a net capability of 196 megawatts and two hydroelectric generating plants with a net capability of 10 megawatts. These facilities provide for a total system operating net capability of 3,281 megawatts. NIPSCO’s transmission system, with voltages from 69,000 to 345,000 volts, consists of 2,805 circuit miles. NIPSCO is interconnected with five neighboring electric utilities. During the year ended December 31, 2016, NIPSCO generated 66.4% and purchased 33.6% of its electric requirements.

Our executive offices are located at 801 East 86th Avenue, Merrillville, Indiana 46410, telephone: (877) 647-5990.

USE OF PROCEEDS

Unless otherwise described in the applicable prospectus supplement, we will use the net proceeds from the sale of securities offered by this prospectus and any applicable prospectus supplement for general corporate purposes, including additions to working capital and repayment of existing indebtedness.

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 September 30, 2017	Fiscal Year Ended December 31,
Nine Months Ended September 30, 2017	2016		2015		2014		2013		2012
1.92		2.25		1.81		2.01		1.81		1.61

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 (before allowance for borrowed funds used during construction), 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. The results of operations for NiSource’s former Columbia Pipeline Group Operations segment are treated as discontinued operations for all periods.

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 former Shareholder Rights Plan, which was effectively terminated in 2006 and formally expired in 2010.

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 a majority of the combined voting power of all of the then-outstanding shares of stock of NiSource voting together as a single class. 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 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 filed 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 prospectus 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;

•

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;

•

restrictions on transfer, sale or other assignment, 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

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 may issue debt securities, which will be designated as either senior debt securities or subordinated debt securities, in one or more series from time to time. Unless the context requires otherwise, references to “debt securities” refer collectively to both the senior debt securities and the subordinated debt securities. The senior debt securities will be issued under an indenture, dated as of November 14, 2000, as supplemented, between NiSource (as successor to NiSource Finance Corp.) and The Bank of New York Mellon (as successor in interest to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as trustee. We refer to this indenture as the “Senior Indenture.” The subordinated debt securities will be issued under a separate indenture to be entered into at a future date between NiSource and The Bank of New York Mellon, as trustee. We refer to this indenture as the “Subordinated Indenture” and, together with the Senior Indenture, as the “Indentures.” The Bank of New York Mellon, as trustee under the Indentures, will act as indenture trustee for the purposes of the Trust Indenture Act. We have filed the Indentures as exhibits 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 Indentures. This section does not contain a complete description of the debt securities or the Indentures. The description of the debt securities is qualified in its entirety by the provisions of the Indentures. References to section numbers in this description of the debt securities, unless otherwise indicated, are references to section numbers of each Indenture.

General

The Indentures do not limit the amount of debt securities that may be issued. Each 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’s board of directors or a committee of the board.

The senior debt securities:

•

are direct senior unsecured obligations of NiSource; and

•

are equal in right of payment to any other unsecured and unsubordinated debt of NiSource.

The subordinated debt securities:

•

are direct subordinated unsecured obligations of NiSource; and

•

are subordinated to the prior payment in full of the senior debt securities of NiSource.

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. Substantially all 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 regulatory restrictions. In addition, NIPSCO’s debt indenture provides that NIPSCO 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).

If NiSource 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 and type of the debt securities;

•

any limit on the aggregate principal amount;

•

the date or dates on which NiSource will pay principal;

•

the right, if any, to extend the date or dates on which NiSource 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 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 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 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 may redeem securities;

•

whether bearer securities will be issued;

•

the denominations in which NiSource will issue securities;

•

the currency or currencies in which NiSource 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 applicable to the debt securities;

•

whether NiSource will pay additional amounts in respect of taxes and similar charges on debt securities held by a United States alien and whether NiSource may redeem those debt securities rather than pay additional amounts;

•

whether NiSource 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;

•

particular terms of subordination with respect to subordinated debt securities; and

•

any other terms of the securities consistent with the provisions of the applicable indenture.

The Indentures do not give holders of debt securities protection in the event of a highly leveraged transaction or other transaction involving NiSource. The Indentures also do not limit the ability of NiSource to incur indebtedness or to declare or pay dividends on its capital stock.

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 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 will issue registered debt securities in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. (See Section 302.)

If NiSource issues the debt securities as registered securities, NiSource 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 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 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 and the securities registrar. No service charge will apply to any exchange or registration of transfer, but NiSource may require payment of any taxes and other governmental charges as described in the applicable Indenture. (See Section 305.)

If debt securities of any series are redeemed, NiSource 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 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 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 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 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 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 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 may redeem a series of debt securities prior to its stated maturity. NiSource 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.

(See Section 1104.)

On or before any redemption date, NiSource 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 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, provided that any debt securities issued as global securities will be selected for redemption in accordance with the policies and procedures of the depositary. 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

NiSource shall not 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’s obligations under the Indentures;

•

after giving effect to the transaction, NiSource is not in default under the Indentures; and

•

NiSource delivers to the indenture trustee an officer’s certificate and an opinion of counsel to the effect that the transaction complies with the Indentures.

(See Section 801.)

Limitation on Liens

As long as any debt securities remain outstanding, neither 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 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).

The lien limitations do not apply to 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 applicable Indenture;

•

assume existing mortgages on any property or indebtedness of an entity which is merged with or into, or consolidated with 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;

•

continue mortgages existing on the date of the applicable Indenture; and

•

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 Indentures provide, with respect to any outstanding series of debt securities, that any of the following events constitutes an “Event of Default”:

•

NiSource 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 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 defaults in the deposit of any sinking fund payment when due and the default continues for three business days;

•

NiSource defaults in the performance of or breaches any covenant or warranty in the applicable Indenture for 90 days after written notice to NiSource from the indenture trustee or to NiSource and the indenture trustee from the holders of at least 33% of the outstanding debt securities of that series;

•

NiSource defaults under any bond, debenture, note or other evidence of indebtedness for money borrowed by it or 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 from the indenture trustee or to NiSource and the indenture trustee from the holders of at least 33% of the outstanding debt securities of that series; or

•

certain events of bankruptcy, insolvency or reorganization of 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 applicable 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 applicable 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 applicable 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

•

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) if NiSource 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 applicable Indenture.

(See Section 502.)

Modification of Indentures

NiSource and the indenture trustee may modify or amend one or both of the Indentures, 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’s covenants or to surrender any right or power conferred on 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 trust 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); or

•

to conform the Indenture to any amendment of the Trust Indenture Act.

(See Section 901.)

Each 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 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 to maintain an office or agency in each place of payment or to maintain an office or agency outside the United States; 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 Indentures, NiSource 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 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 applicable Indenture will cease to be of further effect and NiSource’s obligations will be satisfied and discharged with respect to that series (except as to NiSource’s obligations to pay all other amounts due under the applicable Indenture and to provide certain officers’ certificates and opinions of counsel to the indenture trustee). At the expense of NiSource, 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 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 will issue global securities as fully registered securities registered in the name of DTC’s nominee, Cede & Co. NiSource 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 holds and provides asset servicing for over 3.5 million U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments that DTC’s participants deposit with DTC. 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. The Depository Trust & Clearing Corporation is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. The Depository Trust & Clearing Corporation is owned by the users of its regulated subsidiaries. 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 to be 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 interests in the securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in 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., or such other name as may be requested by an authorized

representative of DTC. The deposit of global securities with, or on behalf of, DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any changes 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.

Redemption notices will be sent to DTC. 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.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the global securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to NiSource 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., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information on the payable date in accordance with their respective holdings shown on DTC’s records. 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 registered in “street name,” and will be the responsibility of the participant and not of DTC, NiSource or the indenture trustee, subject to any statutory or regulatory requirements. Payment of redemption proceeds, principal and any premium, interest or other payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of NiSource 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.

Except as provided in the applicable prospectus supplement, a beneficial owner will not be entitled to receive physical delivery of a security. Accordingly, each beneficial owner must rely on the procedures of DTC to exercise any rights with respect to such beneficial owner’s interest in a global security. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in the global securities.

DTC may discontinue providing its services as securities depositary with respect to the global securities at any time by giving reasonable notice to NiSource 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 to the holders of record.

NiSource may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary). NiSource understands, however, that under current industry practices, DTC would notify its participants of NiSource’s decision, but will only withdraw beneficial interests from the global securities at the request of each participant. In that event, certificates for the securities will be printed and delivered to the applicable participants.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of this information. We have

no responsibility for the performance by DTC or its participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

Governing Law

Each of the Indentures is, and the related senior debt securities and subordinated debt securities will be, 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 Indentures. 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 Indentures 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.)

Because The Bank of New York Mellon is the trustee under the Senior Indenture and the Subordinated Indenture, it may be required to resign as trustee under one of those Indentures if there is an event of default under an Indenture.

We may appoint an alternative trustee for any series of debt securities. The appointment of an alternative trustee would be described in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

NiSource may issue warrants to purchase equity or debt securities. NiSource may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. NiSource will issue the warrants under warrant agreements to be entered into between NiSource and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant 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 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 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.

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’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.

The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. The description in the prospectus supplement will only be a summary, and you should read the stock purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units. Material U.S. federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

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 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 prospectus supplement will also state the proceeds to us from the sale of offered securities, any initial public offering price and other terms of the offering of those offered securities.

Our agents, underwriters and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

We may authorize agents, underwriters or dealers to solicit offers by certain institutions to purchase offered securities from us at the public offering price and on terms described in the related prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. If we use delayed delivery contracts, we will disclose that we are using them in our prospectus supplement and will tell you when we will demand payment and delivery of the securities. The delayed delivery contracts will be subject only to the conditions we set forth in our prospectus supplement.

We may enter into agreements to indemnify agents, underwriters and dealers against certain civil liabilities, including liabilities under the Securities Act of 1933.
