                    MEMORANDUM
TO:    All Employees               
FROM:    Mac Crawford               
DATE:    February 12, 2004               
RE:    Integration Update               

We have now reached another important milestone in the merger process.

 

Yesterday, the Federal Trade Commission (FTC) announced completion of its review of our proposed merger, and has granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

 

Additionally, various state attorneys general have now completed their review and closed their investigation of the transaction.

 

While these are critical milestones, we are not yet able to predict the exact completion date of the merger as the transaction remains subject to additional conditions, including shareholder approval. However, we continue to work toward closing the transaction as expeditiously as possible.

 

We recognize the hard work that all of you continue to do on behalf of both companies, and thank you again for your support. We are confident that with continued dedicated effort, our new combined company will not only be recognized as a great company but also as an industry leader.

 

We will continue to update you when significant news about the merger process becomes available.

 

If you have specific questions about the merger process, please send them to integration.questions@caremark.com.
