Notwithstanding the foregoing, neither such inquiries nor any other inquiries conducted at any time by such Purchaser shall modify, amend or affect such Purchaser’s right (x) to rely on the Company’s representations and warranties contained in Article III above or (y) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in this Agreement.

Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Re:        Private Placement by NiSource Inc.

Ladies and Gentlemen:

The undersigned understands that NiSource Inc., a Delaware corporation (the “ Company ”), proposes to enter into a Subscription Agreement (the “ Subscription Agreement ”) with the purchasers party thereto (the “ Purchasers ”) providing for the private placement of shares of common stock, par value $0.01 per share (the “ Securities ”), of the Company.

(a) If (i) the Company has not filed the Registration Statement with the Commission on or prior to the Filing Deadline or the Registration Statement is not declared effective by the Commission on or prior to the Effectiveness Deadline (in each case, other than due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a Holder to the Company for inclusion in the Registration Statement), (ii) during the Effectiveness Period, the Registration Statement ceases to be effective or the Holders are otherwise not permitted to resell Registrable Securities pursuant to the Registration Statement for more than an aggregate of 45 days (which need not be consecutive days) in any 90-day period or more than an aggregate of 105 days (which need not be consecutive days) in any 365-day period (other than (A) due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a Holder to the Company for inclusion in the Registration Statement or (B) for a period of up to 90 days following the filing of a post-effective amendment or in connection with conversion from Form S-1 to Form S-3), or (iii) the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the Holders are unable to sell Registrable Securities without restriction under Rule 144 (any such failure or breach, an “ Event ” and the date of any Event, an “ Event Date ”), then each Holder shall be entitled to a payment, as liquidated damages and not as a penalty, in an amount equal to 0.25% of such Holder’s Liquidated Damages Base per 30-day period, which amount shall accrue daily, for the first 30 days following the applicable Event Date, increasing by an additional 0.25% of such Holder’s Liquidated Damages Base for each subsequent 30-day period, up to a maximum of 1.0% of such Holder’s Liquidated Damages Base per 30-day period (i.e. 0.50% for the period of 31-60 days following the applicable Event Date, 0.75% for the period of 61-90 days following the applicable Event Date and 1.0% for each 30-day period thereafter) (the “ Liquidated Damages ”), subject to the maximum aggregate limitations in Section  2.02(b) . Liquidated Damages payable to a Holder shall cease to accrue when the Event is cured or the Holder no longer owns Registrable Securities, whichever is earlier, and shall be prorated in the event Liquidated Damages cease to accrue prior to the end of the applicable 30-day calculation period.

(b) The parties agree that the maximum aggregate Liquidated Damages payable to a Holder shall be 5% of such Holder’s Liquidated Damages Base, regardless of the number of Events that occur, provided that the maximum aggregate Liquidated Damages payable to a Holder shall be 10% of such Holder’s Liquidated Damages Base to the extent the excess over 5% of the Holder’s Liquidated Damages Base is due to an Event or Events under clause (iii) of Section  2.02(a) .

5

(c) Liquidated Damages shall be paid to each Holder in immediately available funds within ten Business Days of the end of each applicable 30-day calculation period following an Event Date, or such shorter period of time if the applicable Event is cured before the end of any 30-day calculation period. Any Liquidated Damages due under this Section  2.02 shall constitute the Holders’ exclusive remedy for such events.

(a) the Company shall not be required to file a Registration Statement (or any amendment thereto) or, if a Registration Statement has been filed but not declared effective by the Commission, request effectiveness of such Registration Statement, for a period of up to 45 days, if (A) the Company determines in good faith that a postponement is in the best interest of the Company and its stockholders generally due to a pending transaction involving the Company (including a pending securities offering by the Company, or any proposed financing, acquisition, merger, tender offer, business combination, corporate reorganization, consolidation or other significant transaction involving the Company), (B) the Company determines such registration would render the Company unable to comply with applicable securities laws, (C) the Company determines such registration would require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, or (D) audited financial statements as of a date other than the fiscal year end of the Company would be required to be prepared;  provided ,  however , that in no event shall any such period exceed an aggregate of 90 days in any 365-day period; and

(b) the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement (which notice shall not contain any material, non-public information regarding the Company), suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement but may settle any previously made sales of Registrable Securities) if (i) the Company determines that it would be required to make disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential or (ii) the Company has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Company, would adversely affect the Company; provided, however , in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Registration Statement for a period that exceeds an aggregate of 60 days (which need not be consecutive days) in any 180-day period or 105 days (which need not be consecutive days) in any 365-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.
