Catalina Marketing Announces Receipt of Unsolicited Acquisition Proposal from ValueAct Capital.

ST. PETERSBURG, Fla. -- Catalina Marketing Corporation (NYSE:POS) announced today that on February 20, 2007, it received an unsolicited proposal from ValueAct Capital Master Fund, L.P. ("ValueAct") to acquire by merger 100% of the outstanding equity interests of the company that it does not already own for $32.00 per share in cash. Jeffrey W. Ubben, who has served as a director of the company since May 2006, is the co-founder, managing partner and principal owner of ValueAct.

The receipt of ValueAct's unsolicited proposal followed the company's prior announcement that the previously formed special committee of the board of directors had determined not to proceed with any of the interested parties that had submitted offers to acquire the company. The company has advised ValueAct that its proposal is under consideration by the company's board of directors in consultation with its advisors. The company's board of directors, in turn, has appointed a special committee to consider the appropriate response to the proposal from ValueAct. No decision with respect to the sale of the company has been made. As a matter of policy, the company does not comment on or provide the market information as to the status of any informal expressions of interest or formal proposals or offers presented to the company from time to time, or the course of discussions with any prospective counterparties, nor will it comment upon any rumors with regard to either of the foregoing or make a further announcement regarding the board of director's consideration of any proposal until such time, if ever, that it enters into a definitive agreement for a completed transaction or is otherwise required to make an announcement.
