TAMPA, Fla., June 5 /PRNewswire-FirstCall/ — OSI Restaurant Partners, Inc. (NYSE:OSI) announced that, at a special meeting of stockholders reconvened today, OSI’s stockholders adopted the Agreement and Plan of Merger, dated as of November 5, 2006, among OSI, Kangaroo Holdings, Inc. and Kangaroo Acquisition, Inc., as amended on May 21, 2007. Kangaroo Holdings, Inc. is controlled by an investor group comprised of investment funds associated with Bain Capital Partners, LLC and investment funds affiliated with Catterton Management Company, LLC. OSI’s founders, certain holders associated with one of its founders and certain members of its management are expected to exchange shares of OSI’s common stock for shares of Kangaroo Holdings, Inc. in connection with the merger.

The amended merger agreement was adopted by the holders of a majority of OSI’s outstanding common stock, as required by Delaware law. In addition, the holders of a majority of the number of shares of OSI’s common stock held by holders that are not Participating Holders (as defined in the amended merger agreement) voted for the adoption of the amended merger agreement and the merger, as required by a condition to closing under the amended merger agreement.

OSI expects that the transactions contemplated by the amended merger agreement will be consummated on or prior to June 19, 2007, subject to satisfaction of the conditions to closing under the amended merger agreement. Under the terms of the amended merger agreement, each outstanding share of OSI’s common stock (other than shares held in OSI’s treasury, shares owned by OSI’s subsidiaries, Kangaroo Holdings, Inc. or Kangaroo Acquisition, Inc. and shares held by stockholders who perfect appraisal rights in accordance with Delaware law) will be converted into the right to receive $41.15 in cash. OSI’s founders, Messrs. Sullivan, Basham and Gannon, have agreed with Kangaroo Holdings, Inc. that they will receive only $40.00 per share in cash for their shares (other than shares they will be contributing to Kangaroo Holdings, Inc. in exchange for its stock, which will be exchanged at a per share valuation of $40.00 per share) in a sale transaction with a member of the investor group consummated immediately prior to, but expressly conditioned upon, the consummation of the merger.
