Armin M. Kessler, Chairman of the Special Committee, added: "After extensive negotiations and careful and thorough analysis, together with our independent advisors, the Special Committee and our Board endorsed this transaction as being in the best interest of the Company and our stockholders. We are pleased that this transaction appropriately recognizes the value of PRA as one of the world's leading global CROs while providing our stockholders with an immediate cash premium for their investment in PRA.  In Genstar, we are pleased to have an experienced group of investors committed to maintaining our company's client-focused culture, building upon our core therapeutic expertise, and expanding our product offering across all business segments."

Under the agreement, PRA may solicit proposals for alternative transactions from third parties for a 50-day period ending on September 12, 2007.

In accordance with the agreement, the Board of Directors, through its Special Committee and with the assistance of its independent advisors, intends to actively solicit superior proposals during this period.  There can be no assurances that this solicitation will result in an alternative transaction.
