Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of the Company's common stock pursuant to the NiSource Inc. 2010 Omnibus Incentive Plan. Subject to certain forfeiture conditions, the RSUs will 100% vest on February 26, 2021 provided that the reporting person is continuously employed by the Company through and including that date.
(2)	This figure has been reduced by (1) 21,636 shares underlying the performance share units ("PSUs") granted to the reporting person on January 29, 2016, and (2) 37,904 shares underlying the PSUs granted to the reporting person on January 26, 2017. These PSUs were previously reported on Forms 4 as beneficially owned by the reporting person. However, the vesting of these PSUs is subject to the satisfaction and confirmation of performance measures not based solely on the market price of the Common Stock. As such, the reporting person may not be deemed to beneficially own these PSUs until the performance measures are satisfied and confirmed.
(3)	Constitutes shares acquired though the NiSource Inc. Retirement Savings Plan through January 25, 2018.
