      Based in St. Petersburg, Fla., Catalina Marketing Corporation (www.catalinamarketing.com)

      access. This combination of insight and access provides marketers with

      Certain statements in the preceding paragraphs are forward-looking, 
      and actual results may differ materially. Statements not based on 
      historic facts involve risks and uncertainties, including, but not 
      limited to, the occurrence of any event, change or other circumstances 
      that could give rise to the termination of the merger agreement with 
      ValueAct; the outcome of any legal proceedings that may be instituted 
      against the Company related to the merger agreement; the inability to 
      complete the merger due to the failure to obtain stockholder approval 
      for the merger or the failure to satisfy other conditions to completion 
      of the merger; risks that the proposed transaction diverts management or 
      disrupts current plans and operations and any potential difficulties in 
      employee retention as a result of the merger; the impact of the 
      substantial indebtedness to be incurred to finance the consummation of 
      the merger; the outcome of the consideration of other acquisition 
      proposals by the special committee of the board of directors; and, to 
      the extent the Company elects to move forward to negotiate with respect 
      to or enter into any transaction with another potential acquirer, the 
      possibility that negotiations do not result in a definitive agreement, 
      result in an offer superior to the ValueAct agreement or that, any 
      agreement, if entered into, may not close due to a variety of potential 
      factors.
