CVS Caremark Corporation (CVS)

Opinion of Evercore Group L.L.C.

     Evercore has acted as one of CVS’ financial advisors in connection with the merger. Evercore was requested to act as a financial advisor to CVS in late October 2005 to explore a potential transaction with Caremark and was formally engaged pursuant to a letter agreement dated April 21, 2006. In connection with Evercore’s engagement, the CVS board of directors requested that Evercore render an opinion to the CVS board of directors as to the fairness, from a financial point of view, of the exchange ratio to CVS. At the meeting of the CVS board of directors on February 12, 2007, Evercore rendered its oral opinion, which was subsequently confirmed in writing dated as of the same date, that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered, and qualifications and limitations set forth in its written opinion, which are described below, the exchange ratio was fair, from a financial point of view, to CVS.

     The full text of Evercore’s written opinion, dated February 12, 2007, which sets forth, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken in connection with its opinion, is attached as Exhibit 99.3 to this document and is incorporated by reference into this document. The summary of Evercore’s fairness opinion set forth in this document is qualified in its entirety by reference to the full text of the opinion.

     Evercore’s opinion is addressed to the board of directors of CVS, and addresses only the fairness, from a financial point of view, of the exchange ratio to CVS. Evercore’s opinion does not address the underlying decision by CVS to engage in the merger and does not constitute a recommendation to any stockholder of CVS, Caremark or any other person as to how such person should vote or act on any matter relating to the proposed merger.
