Robbins Geller Rudman & Dowd LLP ("Robbins Geller") today announced that a class action has been commenced in the United States District Court for the Southern District of Texas on behalf of all holders of Crestwood Midstream Partners LP ("Crestwood") (NYSE:CMLP) common units on May 6, 2013, in connection with the proposed takeover of Crestwood by Inergy, L.P. ("Inergy").

If you wish to serve as lead plaintiff, you must move the Court no later than 60 days from today. If you wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact plaintiff's counsel, Darren Robbins of Robbins Geller at 800/449-4900 or 619/231-1058, or via e-mail at djr@rgrdlaw.com. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

The complaint charges Crestwood and the Board of Directors of Crestwood's general partner, Crestwood Gas Services GP LLC ("Crestwood GP") (the "Board"), with violations of the Securities Exchange Act of 1934 ("1934 Act"). Crestwood is a master limited partnership focused on providing midstream infrastructure solutions for the development of North American shale and unconventional resource basins.

The complaint alleges that Crestwood, the Board, Inergy and its affiliates, and Crestwood's financial advisor breached their fiduciary duty, and/or aided and abetted such breaches, in connection with their attempt to consummate the proposed acquisition of Crestwood by Inergy (the "Proposed Acquisition") pursuant to an unfair process and for an unfair price. In addition, the complaint alleges Crestwood and the Board disseminated a false and misleading proxy statement in violation of §§14(a) and 20(a) of the 1934 Act and SEC Rule 14a-9 promulgated thereunder in connection with the Proposed Acquisition.

On May 6, 2013, Crestwood and Inergy announced that they had entered into a definitive agreement (the "Merger Agreement") whereby Inergy would acquire all of Crestwood's outstanding units. Thereafter, on May 29, 2013, defendants caused a Registration Statement on Form S-4 (the "S-4") to be filed with the SEC and disseminated in connection with the upcoming unitholder vote on the Proposed Acquisition. The complaint alleges the S-4 contains a number of false and misleading statements that are material to unitholders who are expected to rely upon the S-4 to determine whether to approve the Proposed Acquisition. The S-4 omits a number of material facts necessary to make statements made therein not false and misleading, including the events leading to the Merger Agreement, the analysis conducted by the Board's financial advisors, and the conflicts of interest burdening the various parties to the deal, including one of Crestwood's financial advisors, Citigroup Global Markets Inc.

Plaintiff seeks injunctive and equitable relief on behalf of all holders of Crestwood common units on May 6, 2013. The plaintiff is represented by Robbins Geller, which has expertise in prosecuting investor class actions and extensive experience in actions involving financial fraud.
