Explanation of Responses:
1. Each subordinated unit will convert into one common unit at the end of the subordinated period described in the Registration Statement on Form S-1 (File No. 333-198990) of Columbia Pipeline Partners LP (the "Issuer"). The subordinated units have no expiration date.
2. In connection with the initial public offering of the Issuer's common units and pursuant to that certain Contribution, Conveyance and Assumption Agreement, by and among the Issuer, NiSource Inc. ("NiSource"), Columbia Pipeline Group, Inc. ("CPG"), Columbia Energy Group ("CEG"), and the other parties thereto, dated February 11, 2015, CEG contributed certain assets to the Issuer in exchange for 46,811,398 subordinated units representing a 46.5% limited partner interest in the Issuer.
3. This Form 3 is being filed jointly by NiSource and CPG. The subordinated units are owned directly by CEG. CPG directly owns 100% of outstanding common stock of CEG and NiSource directly owns 100% of the oustanding common stock of CPG. Accordingly, NiSource and CPG may be deemed to indirectly own the subordinated units of the Issuer held directly by CEG, but each disclaims beneficial ownership except to the extent of its pecuniary interest therein.
