Caremark’s Chairman, President and CEO Emphasizes the Benefits of Merger with CVS

NASHVILLE, TN – January 10, 2007 – At today’s JP Morgan 25th Annual Healthcare Conference, Mac Crawford, Chairman, President and CEO of Caremark Rx, Inc. (NYSE: CMX) reiterated Caremark’s strong commitment to the CVS/Caremark transaction and emphasized the benefits of the merger with CVS to shareholders.

“The CVS/Caremark combination will provide our customers and consumers with exactly what they’ve been asking for: direct contact and access to pharmacists and/or clinicians, and the ability to get the most value for their healthcare dollar,” said Crawford. “Our clients are eager to hear more about the new products and services that will be available to them upon completion of the CVS/Caremark merger.”

Mr. Crawford stressed that a CVS/Caremark merger provides for:

 

    Significant strategic benefits
    Financial benefits that are concrete
    Expected first quarter close, ensuring minimal business disruption

CVS/Caremark would have a strong financial position, with low leverage and strong cash flow generation that will give the company financial flexibility. This will allow the new company to consider such options as dividends and share buybacks.

“The Caremark and CVS management teams have great experience in handling mergers with significant size and scale. We strongly believe that the CVS/Caremark combination will offer near and long-term benefits for our shareholders, customers and consumers. We are committed to making this work.”

Mr. Crawford concluded today’s presentation by recommending shareholders to vote in favor of the merger agreement with CVS Corporation.
