Columbia Pipeline Partners LP Encourages Unitholders to Vote at Reconvened Special Meeting on February 16, 2017

HOUSTON, TEXAS--(Marketwired - Feb. 13, 2017) - Columbia Pipeline Partners LP (NYSE:CPPL) (CPPL) reminds unitholders that the reconvened special meeting of unitholders will be held at 9 a.m. (Central Time) on February 16, 2017 at 1001 Fannin St., Suite 2500, Houston, Texas 77002.

The purpose of the reconvened special meeting is to vote on a proposal to approve the Agreement and Plan of Merger dated as of November 1, 2016 (the "Merger Agreement"), by and among CPPL, Columbia Pipeline Group, Inc. ("CPG") and their respective affiliates, pursuant to which a wholly owned subsidiary of CPG will merge with and into CPPL such that CPPL will become a wholly owned subsidiary of CPG (the "Merger"). Approval of the Merger requires both the affirmative vote of (i) a majority of the outstanding common units excluding units held by affiliated unitholders and (ii) a majority of the outstanding common units.

The special meeting was originally scheduled for February 7, 2017 but was reconvened to February 16, 2017 because a quorum was not obtained. Quorum requires the presence, in person or by proxy, at the special meeting of holders of a majority of the outstanding CPPL common units as of January 4, 2017, the record date of the special meeting. CPPL adjourned the special meeting to February 16, 2017 to allow for additional time to solicit proxies from unitholders.

As the reconvened special meeting approaches, approximately 98% of the votes cast to date are in support of the Merger. Each of Institutional Shareholder Services (ISS), Glass, Lewis & Co. and Egan-Jones Proxy Services has recommended that CPPL unitholders vote "FOR" the proposal to approve the Merger Agreement.

Unless we obtain both a quorum for the special meeting and the required unitholder approval, the Merger cannot take place. CPPL has been advised by CPG that CPG has no intention of increasing the price or varying any of the terms of the Merger Agreement. Common unitholders who have not already submitted a proxy are encouraged to do so as soon as possible and should contact D.F. King, CPPL's proxy solicitor, by calling toll-free at 212 232 3235 or 212 232 3233.

The record date for determining unitholders eligible to vote at the special meeting will remain the close of business on January 4, 2017. Valid proxies submitted by common unitholders prior to the adjourned February 7, 2017 special meeting continue to be valid for purposes of the reconvened special meeting scheduled for February 16, 2017.
