online at <I>www.computershare.com/investor</I>. Please allow 30 days from the date the Plan Administrator receives your request for the direct deposit to be established. If you do not receive your cash dividends by direct deposit, the Plan

the address under Question 4 above. There will be a service fee of $25 if you request a certificate online or $40 if you request a certificate by calling the Plan Administrator directly, but there is no service fee if you submit a written request to
the Plan Administrator. A certificate will be mailed by first class mail, within two business days of the Plan Administrator&#146;s receipt of your request, to your address of record. The issuance of Plan shares in certificate form will not change
your reinvestment election unless you direct otherwise. Any remaining whole or fractional shares of our common stock will continue to be credited to your account. Under the terms of the Plan, Computershare will not issue certificates for fractional
shares of our common stock. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><A NAME="toc487148_47"></A>Reports to Participants </B></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">You may terminate your participation in the Plan at any time by giving instructions to the Plan Administrator. The Plan Administrator will
continue to hold your shares unless you request them to be sold or issued. At your request, the Plan Administrator will send to you a certificate for the whole shares and a check for any fractional share of NiSource common stock in your Plan
account, less any applicable fees and transfer taxes. Alternatively, at your request, the Plan Administrator will sell all or a portion of such shares and remit to you the proceeds less any applicable fees and transfer taxes. If the Plan
Administrator receives your termination request near a record date for a dividend payment, the Plan Administrator, in its sole discretion, may either pay any such dividend in cash or reinvest it in shares on your behalf. Any optional cash
investments sent to the Plan Administrator prior to your termination request also will be invested unless you expressly request that the optional cash investment be returned and your request is received at least two business days prior to the
relevant investment date. In every case of termination, your interest in a fractional share will be paid in cash less any applicable fees and any other costs of sale. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><I><A NAME="toc487148_54"></A>34. Under what circumstances will NiSource terminate my participation in the Plan? </I></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">At any time, for any reason and at our discretion, we may instruct the Plan Administrator to terminate your participation in the Plan effective
immediately upon mailing a notice to you at your address of record. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Plan Administrator automatically will terminate your Plan account
if you withdraw all of your whole and fractional shares. The Plan Administrator also may terminate your Plan account if your share balance is less than one share of NiSource common stock. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the event of your death or adjudication of incompetency, the Plan Administrator may terminate your Plan account and distribute the proceeds
as described above under Question 33. The Plan Administrator will continue to maintain your Plan account, however, until the Plan Administrator receives satisfactory written notice of your death or adjudication of incompetency. In addition, the Plan
Administrator must receive satisfactory proof of the appointment of a legal representative who is authorized to instruct the Plan Administrator on the termination of your Plan account and receive the proceeds thereof. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">At its discretion, the Plan Administrator also may close any Plan account that contains less than one share of NiSource common stock. Any
fractional share in your Plan account will be sold subject to the fees as described above. A check for the sale proceeds less applicable fees will be mailed to your address of record. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any stock dividends or stock split shares that we distribute will be credited directly to your Plan account. Stock split or stock dividend
shares distributed on shares you hold in certificate form also will be credited to your Plan account. If you are entitled to participate in a rights offering, the right to subscribe will be based on the total number of shares owned, both inside and
outside the Plan. Any rights certificates to be distributed as a result of any rights agreement will be distributed based on whole shares only. Transaction processing may be temporarily suspended during such distributions. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><I><A NAME="toc487148_57"></A>36. What are my rights as a stockholder under the Plan with regard to voting, proxies and stockholder
communications? </I></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">You will have the exclusive right to exercise all voting rights with respect to whole shares of our common stock
credited to your Plan account. You will receive proxy materials from us for each stockholder meeting, including a proxy statement and a form of proxy covering all whole shares credited to your account and all shares of stock registered in your name
outside of the Plan as of the record date for the stockholder meeting. You will also have the right to receive all other communications that we send to the holders of common stock. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following is only a summary of the tax consequences of participation in the Plan as of the date of this prospectus. Tax laws and
regulations may change and this summary may not reflect every possible situation that could result from participating in the Plan. Accordingly, you should consult with your own tax advisor with respect to the federal, state, local, foreign and
withholding tax consequences applicable to your particular situation. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In general, cash dividends paid by us with respect to your shares are considered taxable income
even if they are reinvested. Your cost basis for federal income tax purposes on any shares purchased through the Plan is the price at which the shares are purchased, as reflected on your Plan statement or transaction advice. Trading fees paid by us
on your behalf also are considered taxable income and are included in the cost basis of shares purchased. The Form 1099 sent both to you and the Internal Revenue Service at the end of the year shows trading fees paid by us. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If you make optional cash investments that are subject to a waiver discount, you may be treated as receiving a dividend distribution equal to
the discount. The tax treatment of a waiver discount is unclear, and you should consult your tax advisor to determine how you should treat a waiver discount for tax purposes. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Most likely, you will realize taxable income or loss for federal income tax purposes when shares are sold. Your tax basis for shares that are
sold is the price paid for the shares. The price paid is reflected on your statement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Your holding period for shares purchased through
the Plan begins on the day following the applicable investment date. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For Plan participants who are subject to <FONT
STYLE="white-space:nowrap">back-up</FONT> withholding or <FONT STYLE="white-space:nowrap">non-U.S.</FONT> investors who are subject to U.S. federal tax withholding, the amount of dividends that may be reinvested will be net of the tax withheld. <FONT

<P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><I><A NAME="toc487148_59"></A>38. Can the Plan be modified or discontinued? </I></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We and the Plan Administrator reserve the right to suspend, modify or terminate the Plan at any time. We will send notice of any suspension,
modification or termination of the Plan to all participants, who will have in all events, the right to withdraw from participation. In addition, the Plan Administrator may terminate the participation of any participant, interpret, modify fees and
regulate the Plan as it deems necessary or desirable in connection with its operation. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If we or the Plan Administrator terminate the
Plan, or if we are involved in a reorganization or merger, your shares enrolled in the Plan as well as your current elections under the Plan may automatically roll over to a subsequent survivor or successor Plan. </P>

participation in the Plan? </I></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Your investment in shares credited to your Plan account is no different than your investment in shares of
NiSource common stock that you hold in certificate form or in a brokerage or bank account. You alone bear the risk of fluctuations in the market value of your shares of NiSource common stock. You bear the risk of loss in value and you enjoy the
benefits of gains from market price changes with respect to all of your shares. However, with respect to shares held in your Plan account, you may lose an advantage otherwise available in that you are not able to select more specifically the timing
of your investment or the sale of your shares. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Neither we nor the Plan Administrator provide any advice or make any recommendations with
respect to any purchase or sale transaction you initiate. Neither we nor the Plan Administrator can guarantee that the value of the shares purchased under the Plan will, at any particular time, be more than your original investment. You need to make
independent investment and participation decisions based on your own judgment and research. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Neither we nor the Plan Administrator can
guarantee liquidity in the market, thus your investments and the marketability of your shares may be adversely affected by the market conditions at the time you seek to sell your shares. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Shares of NiSource common stock credited to your Plan account in book-entry form through the Plan are not subject to protection under the

required to pay certain fees in connection with the Plan. See &#147;Terms of the Plan&#151;Summary of Plan Fees&#148; for a description of the fees charged under the Plan. All other costs related to the Administration of the Plan will be paid by us.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In connection with the Plan, we may be requested to approve requests for waivers of the Plan&#146;s annual investment maximum by or on

through the Plan and resell them shortly after acquiring them, including coverage of short positions, under certain circumstances, may be participating in a distribution of securities that would require compliance with Regulation M under the
Securities Exchange Act of 1934 and may be considered to be underwriters within the meaning of the Securities Act of 1933. We will not extend to any such person any rights or privileges other than those to which such person would be entitled as a
participant, nor will we enter into any agreement with any such person regarding the resale or distribution by any such person of the shares of our common stock so purchased. We may, however, accept optional cash payments and initial investments
made pursuant to waiver requests by such persons. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">From time to time, financial intermediaries, including brokers and dealers, and other
persons may engage in positioning transactions in order to benefit from any waiver discounts applicable to investments made pursuant to waivers approved under the Plan. Those transactions may cause fluctuations in the trading volume of our common
stock. Financial intermediaries and such other persons who engage in positioning transactions may be deemed to be underwriters. We have no arrangements or understandings, formal or informal, with any person relating to the sale of shares of our
common stock to be received under the Plan. We reserve the right to modify, suspend or terminate participation in the Plan by otherwise eligible persons to eliminate practices that are inconsistent with the purposes of the Plan. </P>
