The TriZetto Group, Inc. (NASDAQ: TZIX) announced today that the Delaware Court of Chancery vacated its earlier order preliminarily enjoining TriZetto from allowing any vote by TriZetto’s stockholders upon a proposal to approve the merger pursuant to which TriZetto will become a wholly-owned subsidiary of TZ Holdings, L.P., an entity that is majority-owned by Apax Partners L.P. The preliminary injunction was vacated based upon TriZetto’s agreement to provide additional disclosures in its proxy materials regarding the potential financial benefits of the merger to UBS Securities LLC, TriZetto's financial advisor. The additional disclosure materials have been filed with the Securities and Exchange Commission (SEC) and are being mailed to the stockholders, clearing the way for the stockholder vote on the proposed merger.

The special meeting of stockholders called to vote on the merger was convened as scheduled on June 30, 2008, but as a result of the injunction was adjourned until July 14, 2008, at 10:00 a.m., local time, at The Island Hotel Newport Beach, 690 Newport Center Drive, Newport Beach, California 92660.
