Catalina announced on April 17, 2007 a definitive agreement to be acquired by affiliates of Hellman & Friedman in a transaction valued at approximately $1.7 billion. Under terms of the agreement, Catalina shareholders will receive $32.50 per share in cash, without interest, for each share of Catalina common stock held.

"We believe Catalina Marketing is in a great position to focus on future growth initiatives and strategic opportunities as a private company," said Dick Buell, chief executive officer of Catalina Marketing. "With the financial support of Hellman & Friedman, we are confident that we can accomplish the future plans we have set forth. H&F has extensive knowledge of the marketing and technology arena that will help us continue to build on our established, strong foundation and move the company into the next chapter of growth and development."

Catalina stock will cease to trade on the New York Stock Exchange at market close today, and will no longer be listed. Catalina has appointed Mellon Investor Services LLC as its paying agent, and, as soon as practicable, will mail a letter of transmittal and instructions to all Catalina shareholders of record. The letter of transmittal and instructions will contain information regarding how to surrender Catalina common stock in exchange for the merger consideration. Shareholders of record should be in receipt of the letter of transmittal before surrendering their shares. Shareholders who hold shares through a bank or broker will not have to take any action to have their shares converted into cash as such conversions will be handled by the bank or broker.
