SUBJECT TO COMPLETION, DATED JANUARY 16, 2007

MERGER PROPOSED – YOUR VOTE IS VERY IMPORTANT

The boards of directors of CVS Corporation and Caremark Rx, Inc. have each approved a merger agreement which provides for the combination of the two companies in a transaction structured as a merger of equals. The boards of directors of CVS and Caremark believe that the combination of the two companies will be able to create substantially more long-term stockholder value than either company could individually achieve. Following the completion of the merger, Caremark will be a wholly owned subsidiary of CVS and Caremark stockholders will own approximately 45.5% of the outstanding common stock of the combined company and CVS stockholders will own approximately 54.5% of the outstanding common stock of the combined company, in each case, on a fully diluted basis. CVS Corporation is referred to as CVS and Caremark Rx, Inc. is referred to as Caremark.

The combined company will be named CVS/Caremark Corporation and the shares of the combined company will be traded on the New York Stock Exchange, or the NYSE, under the symbol “CVS”.

If the merger is completed, Caremark’s stockholders will receive 1.670 shares of common stock of CVS/Caremark, for each share of Caremark common stock that they own immediately before the effective time of the merger. Caremark stockholders will receive cash for any fractional shares which they would otherwise receive in the merger. Caremark stockholders will also receive a one-time special cash dividend in the amount of $2.00 per share of Caremark common stock held by each such holder on a record date to be set by the Caremark board of directors, which dividend will be conditioned on the completion of the merger and will be paid at or immediately following the effective time of the merger. CVS stockholders will continue to own their existing shares after the merger. CVS common stock is traded on the NYSE under the symbol “CVS”. On January 12, 2007, the last practicable day before the mailing of this document, the closing price per share of CVS common stock as reported by the NYSE was $31.94.

CVS and Caremark estimate that CVS will issue approximately 712.4 million shares of CVS/Caremark common stock in the merger based on the number of shares of Caremark common stock outstanding on January 15, 2007, and will reserve an additional approximately 33.5 million shares of CVS/Caremark common stock for issuance in connection with CVS/Caremark’s assumption of Caremark’s outstanding options and warrants.

YOUR VOTE IS IMPORTANT. The merger cannot be completed unless, among other things, holders of Caremark common stock vote to adopt the merger agreement and approve the merger, and holders of CVS common stock and CVS Series One ESOP Convertible Preference Stock, voting together as a single class, approve the amendments to CVS’ charter and approve the issuance of CVS/Caremark common stock in the merger.

The CVS board of directors unanimously recommends that CVS stockholders vote “FOR” the amendments to the CVS charter to increase the authorized number of shares and to change the name of CVS to “CVS/Caremark Corporation” and “FOR” the issuance of CVS/Caremark common stock to Caremark stockholders in the merger. The Caremark board of directors unanimously recommends that Caremark stockholders vote “FOR” the adoption of the merger agreement and the approval of the merger.

CVS and Caremark will each hold a special meeting of their respective stockholders to vote on these proposals. Whether or not you plan to attend your company’s special meeting, please take the time to vote by completing and mailing the enclosed proxy card or submitting your proxy by telephone or through the Internet, using the procedures in the proxy voting instructions included with your proxy card. Even if you return the proxy, you may attend the special meeting and vote your shares in person.

This document describes the proposed merger and related transactions in more detail. CVS and Caremark encourage you to read this entire document carefully, including the merger agreement, which is included as Annex A, and the section discussing “Risk Factors” relating to the merger beginning on page 27.

CVS and Caremark look forward to the successful combination of the two companies.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
To Be Held On February 23, 2007

Dear Stockholder:

     A special meeting of stockholders of CVS Corporation will be held on February 23, 2007 at 11:00 a.m., Eastern Time, at CVS’ corporate headquarters, One CVS Drive, Woonsocket, Rhode Island 02895.

     The purpose of the CVS special meeting is to consider and to vote upon the following proposals:

  • a proposal to approve the amendments to CVS’ Amended and Restated Certificate of Incorporation, which is referred to as the CVS charter, effective upon completion of the merger, to increase the authorized number of shares of CVS common stock from 1 billion to 3.2 billion and to change the name of CVS Corporation to “CVS/Caremark Corporation”;

  • a proposal to approve the issuance of shares of CVS/Caremark common stock to stockholders of Caremark Rx, Inc. on the terms and conditions set out in the Agreement and Plan of Merger dated as of November 1, 2006 among CVS, Caremark and Twain MergerSub Corp., a wholly owned subsidiary of CVS formed for the purpose of the merger; and

  • a proposal to approve an adjournment or postponement of the special meeting, including if necessary, to solicit additional proxies in favor of the foregoing proposals if there are not sufficient votes for either of the proposals.

     The CVS board of directors has unanimously determined that the amendments to the CVS charter and the share issuance are advisable and in the best interests of CVS and its stockholders and recommends that CVS stockholders vote “FOR” the amendments to the CVS charter, “FOR” the issuance of CVS/Caremark common stock to Caremark stockholders in the merger and “FOR” the adjournment or postponement of the special meeting, including if necessary, to solicit additional proxies in favor of the amendments and issuance.

     CVS and Caremark cannot complete the merger unless:

  • the proposed amendments to the CVS charter are approved by holders of CVS common stock and holders of CVS Series One ESOP Convertible Preference Stock, voting together as a single class, representing at least a majority of the aggregate votes entitled to be cast by all such holders; and

  • the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger is approved by holders of CVS common stock and CVS Series One ESOP Convertible Preference Stock, voting together as a single class, representing at least a majority of the votes cast in person or by proxy at such meeting, so long as the total number of votes cast on the proposal represents over 50% of the total number of votes entitled to be cast by holders of the outstanding CVS common stock and CVS Series One ESOP Convertible Preference Stock, voting together as a single class.

     Your failure to vote will have the same effect as a vote against the approval of the CVS charter amendments and will make it more difficult to obtain the necessary quorum for purposes of approving the share issuance. Therefore, your vote is very important.

     The close of business on January 19, 2007 has been fixed as the record date, which is referred to as the CVS record date, for the determination of CVS stockholders entitled to notice of, and to vote at, the CVS special meeting or any adjournments or postponements of the CVS special meeting. Only holders of CVS common stock and holders of CVS Series One ESOP Convertible Preference Stock of record at the close of business on January 19, 2007 are entitled to notice of, and to vote at, the CVS special meeting or any adjournments or postponements of the CVS special meeting. All CVS Series One ESOP Convertible Preference Stock, which is referred to as the CVS ESOP preference stock, is held by the Bank of New York, as Trustee under the 401(k) Plan and the Employee Stock Ownership Plan of CVS Corporation and Affiliated Companies, which is referred to as the CVS Plan. The CVS Plan consists of both a 401(k) Plan and an Employee Stock Ownership Plan. Each participant in the CVS Plan instructs the trustee of the CVS Plan how to vote his or her shares of (i) CVS ESOP preference stock and (ii) CVS common stock held in the CVS Plan. Unallocated shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan and shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan with respect to which the trustee of the CVS Plan receives no timely voting instructions will be voted by the trustee of the CVS Plan in the same proportion as it votes all the shares as to which such trustee has received timely voting instructions. A list of the holders of CVS common stock entitled to vote at the CVS special meeting will be available for examination by any CVS stockholder, for any purpose germane to the CVS special meeting, at CVS’ principal executive offices at One CVS Drive, Woonsocket, Rhode Island 02895, for ten days before the CVS special meeting, between the hours of 9:00 a.m. and 3:00 p.m., and at the CVS special meeting during the entire time of the meeting.





     We direct your attention to the joint proxy statement/prospectus accompanying this notice for a more complete statement regarding the matters proposed to be acted upon at the meeting. We encourage you to read the entire joint proxy statement/prospectus carefully, including the merger agreement, which is included as Annex A to the joint proxy statement/prospectus, and the section discussing “Risk Factors” beginning on page 27.

     SO THAT YOUR SHARES WILL BE REPRESENTED WHETHER OR NOT YOU ATTEND THE CVS SPECIAL MEETING, PLEASE VOTE AS SOON AS POSSIBLE BY MAIL, BY TELEPHONE OR THROUGH THE INTERNET. INSTRUCTIONS ON THESE DIFFERENT WAYS TO VOTE YOUR PROXY ARE FOUND ON THE ENCLOSED WHITE PROXY FORM. YOU MAY REVOKE YOUR PROXY AT ANY TIME BEFORE IT IS VOTED AT THE CVS SPECIAL MEETING.

QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:      What will happen in the transaction?
 
A:      CVS and Caremark are proposing to combine the two companies in a merger of equals transaction. In the merger, Caremark will be merged with and into a wholly owned subsidiary of CVS that was formed for the purpose of the merger with the CVS subsidiary surviving the merger and remaining a wholly owned subsidiary of CVS. Immediately following the merger, CVS Corporation will be renamed “CVS/Caremark Corporation” and Twain MergerSub LLC will be renamed “Caremark Rx, L.L.C.”. Caremark stockholders will have their shares of Caremark common stock converted into newly issued shares of common stock of CVS/Caremark Corporation, and CVS stockholders will retain their existing shares of CVS common stock and CVS Series One ESOP Convertible Preference Stock, which is referred to as CVS ESOP preference stock. CVS and Caremark expect that, upon completion of the merger, approximately 45.5% of the outstanding common stock of the combined company on a fully diluted basis will be held by former Caremark stockholders, and approximately 54.5% of the outstanding common stock of the combined company on a fully diluted basis will be held by former CVS stockholders.
 
  In the merger, CVS’ Amended and Restated Certificate of Incorporation, which is referred to as the CVS charter, will be amended to increase the number of authorized shares of CVS common stock from 1 billion to 3.2 billion and to change CVS’ name to CVS/Caremark Corporation. These changes are described under the section entitled “CVS Charter Amendment” beginning on page 127.
 
Q:      What will I receive in the merger?
 
A:      CVS Stockholders. Each share of CVS common stock and CVS ESOP preference stock held by CVS stockholders immediately before the merger will continue to represent one share of CVS/Caremark common stock and one share of ESOP preference stock of the combined company, as applicable, after the effective time of the merger. In other words, CVS stockholders will receive no consideration in the merger.
 
  Caremark Stockholders. For each share of Caremark common stock held, Caremark stockholders will have the right to receive 1.670 shares of CVS/Caremark common stock. At the effective time of the merger, each share of Caremark common stock will be cancelled and converted automatically into the right to receive 1.670 shares of CVS/Caremark common stock. Caremark stockholders will receive cash for any fractional shares of CVS/Caremark common stock that they would otherwise receive in the merger. The amount of cash for fractional shares will be calculated by multiplying the fraction of a share of CVS/Caremark common stock to which the Caremark stockholder would be entitled to receive in the merger by the closing sale price of a share of CVS/Caremark common stock on the first trading day immediately following the effective time of the merger.
 
Q:      Will I receive the Caremark special cash dividend?
 
A:      CVS has granted a waiver to Caremark from the restrictions set forth in the merger agreement to permit Caremark to pay a one-time, special cash dividend to holders of Caremark common stock (on a record date to be set by the Caremark board of directors) in the amount of $2.00 per share of Caremark common stock held by each such holder on such record date, which dividend shall be declared prior to the Caremark special meeting, but shall only become payable upon or after the effective time of the merger, and such payment shall be conditioned upon the completion of the merger. You can find further details regarding this dividend in the section entitled “The Merger—Caremark Special Cash Dividend” beginning on page 40.
 
Q:      What is the accelerated share repurchase transaction?
 
A:      CVS and Caremark have agreed that as promptly as practicable after the closing of the merger, CVS/Caremark will execute an accelerated share repurchase transaction on customary terms, whereby CVS/Caremark will retire 150 million shares of its common stock (approximately 9.8% of the combined company’s pro-forma outstanding shares after giving effect to the merger). To implement this transaction, CVS/Caremark will enter into an agreement with one or more financial institutions to purchase shares of common stock from each of them and pay each of them for the shares to be retired. The effect of this transaction and the related borrowing by the combined
 





  company to finance the transaction will be the immediate reduction of shares outstanding by 150 million shares and an increase in the combined company’s funded debt by approximately $4.8 billion. CVS has received commitments for such financing. It is anticipated that the agreement with the financial institutions will provide for a purchase price adjustment mechanism customary for such a transaction. The purchase price adjustment under such agreement may be subject to limits on the amounts that may be owed by CVS/Caremark or the financial institutions or both.
 
Q:      When and where are the CVS and Caremark special meetings?
 
A:      CVS Special Meeting. A special meeting of CVS stockholders, which is referred to as the CVS special meeting, will be held on February 23, 2007 at 11:00 a.m., Eastern Time, at CVS’ corporate headquarters, One CVS Drive, Woonsocket, Rhode Island 02895, to consider and vote on proposals related to the merger.
 
  Caremark Special Meeting. A special meeting of Caremark stockholders, which is referred to as the Caremark special meeting, will be held on February 20, 2007 at 1:00 p.m., Central Time, at the Hilton Nashville Downtown at 121 Fourth Avenue South, Nashville, Tennessee 37201 to consider and vote on proposals related to the merger.
 
Q:      What stockholder votes are required?
 
A:      CVS stockholders are being asked to approve two separate proposals that are necessary to complete the merger. The completion of the merger requires:
 
 
  • the approval of the amendments to the CVS charter by holders of CVS common stock and CVS ESOP preference stock, voting together as a single class, representing a majority of the votes entitled to be cast by such holders on the proposal; and
     
     
  • the approval of the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger by holders of CVS common stock and CVS ESOP preference stock, voting together as a single class, representing a majority of the votes cast in person or by proxy at the CVS special meeting, provided that the total number of votes cast on the proposal represents over 50% of the total number of votes entitled to be cast by holders of the outstanding CVS common stock and CVS ESOP preference stock, voting together as a single class, which is referred to as the 50% “vote cast” quorum requirement.
     
      The CVS board of directors recommends that CVS stockholders vote “FOR” the amendments of the CVS charter to increase the number of authorized shares of CVS common stock and to rename the combined company CVS/Caremark Corporation and “FOR” the issuance of CVS/Caremark common stock in connection with the merger.
     
      Caremark stockholders are being asked to adopt the merger agreement and approve the merger, which requires the approval of holders of a majority of the outstanding shares of Caremark common stock entitled to vote at the Caremark special meeting.
     
      The Caremark board of directors recommends that Caremark stockholders vote “FOR” the adoption of the merger agreement and approval of the merger.
     
    Q:      Why is my vote important?
     
    A:      In order to complete the merger, Caremark stockholders must adopt the merger agreement and approve the merger, and CVS stockholders must approve the issuance of CVS/Caremark common stock to Caremark stockholders in the merger and the amendments to the CVS charter to increase the number of authorized shares of CVS common stock and to rename the combined company CVS/Caremark Corporation.
     
      If you are a CVS stockholder and you abstain from voting or do not vote (either in person or by proxy), or fail to direct your broker how to vote, it will have the same effect as a vote “AGAINST” the proposal to approve the amendments to the CVS charter. If you abstain or do not vote (either in person or by proxy), or fail to direct your broker how to vote, it will have no effect in determining whether the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger will be approved, but will not be
     

    2






      considered to be a “vote cast” for purposes of this proposal, making it more difficult to satisfy the 50% “vote cast” quorum requirement for the proposal.
     
      If you are a Caremark stockholder and you abstain from voting or do not vote (either in person or by proxy), or fail to direct your broker how to vote, it will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement and to approve the merger.
     
    Q:      Are the issuance of CVS/Caremark common stock in the merger and the CVS charter amendments each conditioned upon each other?
     
    A:      Yes. The proposal to amend the CVS charter and the proposal to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger are each conditioned upon the approval of the other and the approval of each such proposal is a condition to completion of the merger. Neither the issuance of CVS/Caremark common stock in connection with the merger nor the amendments of the CVS charter will take place unless both of these proposals are approved by the CVS stockholders and the merger is completed. Therefore, the completion of the merger cannot proceed without the approval of both proposals.
     
    Q:      What do I do if I want to change my vote?
     
    A:      You can change your vote at any time before your proxy is voted at your stockholders’ meeting. You can do this in one of four ways:
     
     
  • you can send a signed notice of revocation;
     
     
  • you can grant a new, valid proxy bearing a later date;
     
     
  • you can vote again by telephone or through the Internet; or
     
     
  • if you are a holder of record, you can attend the applicable special meeting and vote in person, but your attendance alone will not revoke any proxy that you have previously given.
     
      If you choose either of the first two methods, you must send your notice of revocation or your new proxy to your company’s Corporate Secretary at the address under “The Companies” beginning on page 104 no later than the beginning of the applicable special meeting. If you are a CVS stockholder, you can find further details on how to revoke your proxy in “The CVS Special Meeting—Revocation of Proxies” beginning on page 121. If you are a Caremark stockholder, you can find further details on how to revoke your proxy in “The Caremark Special Meeting—Revocation of Proxies” beginning on page 125.
     
    Q:      If my shares are held in “street name” by my broker, will my broker vote my shares for me?
     
    A:      No. Your broker is not permitted to decide how your shares should be voted. Your broker will only vote your shares on a proposal if you provide your broker with voting instructions on that proposal. You should instruct your broker to vote your shares by following the directions that your broker provides you. Please check the voting information form used by your broker to see if it offers telephone or Internet voting.
     
      A broker non-vote occurs when a beneficial owner fails to provide voting instructions to his or her broker as to how to vote the shares held by the broker in street name and the broker does not have discretionary authority to vote without instructions. Brokers do not have discretionary authority to vote on any of the Caremark proposals or CVS proposals. By signing your proxy card and returning it to your broker without specific instructions as to any proposal, your shares represented by that proxy will be voted in favor of that proposal. Any shares you beneficially own not identified as represented by that proxy will be considered broker non- votes. See “The CVS Special Meeting” beginning on page 118 and “The Caremark Special Meeting” beginning on page 123.
     
    Q:      What if I fail to instruct my broker with respect to those items that are necessary to consummate the merger?
     
    A:      If you are a CVS stockholder:
     

    3






     
  • with respect to the proposal to amend the CVS charter, a broker non-vote will be counted towards a quorum at the CVS special meeting, but will have the same effect as a vote “AGAINST” the proposal to amend the CVS charter; and
     
     
  • with respect to the proposal to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger, a broker non-vote will not be considered a “vote cast” for purposes of satisfying the applicable quorum requirement, making it more difficult to obtain the necessary quorum. However, if the quorum requirement is satisfied, a broker non-vote will have no effect on the proposal to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger.
     
      If you are a Caremark stockholder, a broker non-vote will be counted towards a quorum at the Caremark special meeting, but will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement and approve the merger.
     
      For additional information, see “The CVS Special Meeting—Votes Required to Approve CVS Proposals” beginning on page 120 if you are a CVS stockholder, and “The Caremark Special Meeting—Votes Required to Approve Caremark Proposals” beginning on page 124 if you are a Caremark stockholder.
     
    Q:      What do I do now?
     
    A:      Carefully read and consider the information contained in and incorporated by reference into this document, including its annexes.
     
      In order for your shares to be represented at your stockholders’ meeting:
     
     
  • you can vote by telephone or through the Internet by following the instructions included on your WHITE proxy card;
     
     
  • you can indicate on the enclosed WHITE proxy card how you would like to vote and sign and return the proxy card in the accompanying pre-addressed postage paid envelope; or
     
     
  • you can attend your special meeting in person.
     
    Q:      Should I send in my stock certificates now?
     
    A:      No. Caremark stockholders should not send in their stock certificates at this time. If the merger proceeds, CVS’ exchange agent will send former Caremark stockholders a letter of transmittal explaining what they must do to exchange their Caremark stock certificates or transfer uncertificated shares for the merger consideration payable to them.
     
      CVS stockholders will retain their current stock certificates after the merger and should not send in their stock certificates.
     
    Q:      Can I dissent and require appraisal of my shares?
     
    A:      No. Under Delaware law, CVS and Caremark stockholders have no right to an appraisal of the value of their shares in connection with the merger.
     
    Q:      Are there risks involved in undertaking the merger?
     
    A:      Yes. In evaluating the merger, CVS and Caremark stockholders should carefully consider the factors discussed in “Risk Factors” beginning on page 27 and other information about CVS and Caremark included in the documents incorporated by reference into this document.
     
    Q:      When do you expect to complete the merger?
     
    A:      CVS and Caremark are working to complete the merger as quickly as practicable. However, CVS and Caremark cannot assure you when or if the merger will be completed. Completion of the merger is subject to satisfaction or waiver of the conditions specified in the merger agreement, including receipt of the necessary
     

    4






      approvals of CVS’ and Caremark’s stockholders at their respective special meeting and any necessary regulatory approvals. It is possible that factors outside the control of both companies could result in the merger being completed later than expected. Although the exact timing of completion of the merger cannot be predicted with certainty, CVS and Caremark anticipate completing the merger in the first quarter of 2007. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114.
     
    Q:      Do the Caremark stockholders have to vote on the merger with CVS at the Caremark special meeting if Caremark has changed its recommendation of the merger with CVS?
     
    A:      Yes, unless CVS terminates the merger agreement before the Caremark special meeting, Caremark stockholders will be asked to vote on the merger with CVS even if Caremark has changed its recommendation of the merger with CVS consistent with the terms of the merger agreement.
     
    Q:      Whom should I call with questions?
     
    A:      CVS Stockholders. If you have additional questions about the merger, you should contact:

    The Merger

         The Agreement and Plan of Merger, dated as of November 1, 2006, among CVS, Caremark and Twain MergerSub Corp., as amended by Amendment No. 1 to the merger agreement, dated as of January 16, 2007, which is referred to as the merger agreement, is attached as Annex A to this document. Caremark and CVS encourage you to read carefully the merger agreement in its entirety because it is the principal legal agreement that governs the merger.

    Structure of the Merger (see page 40)

         Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, Caremark will merge with and into Twain MergerSub LLC, a wholly owned subsidiary of CVS that was formed for the purpose of the merger, with Twain MergerSub LLC surviving the merger and remaining a wholly owned subsidiary of CVS. Immediately following the merger, CVS Corporation will be renamed “CVS/Caremark Corporation” and Twain MergerSub LLC will be renamed “Caremark Rx, L.L.C.”. Accordingly, after the effective time of the merger, shares of Caremark common stock will no longer be publicly traded.

    Merger Consideration (see page 106)

         Caremark Stockholders. As a result of the merger, Caremark stockholders will be entitled to receive, for each share of Caremark common stock that they own, 1.670 shares of CVS/Caremark common stock. The number of shares of CVS/Caremark common stock delivered in respect of each share of Caremark common stock in the merger is referred to as the exchange ratio. The combined company will not issue any fractional shares of CVS/Caremark common stock in the merger. Instead, Caremark stockholders will receive cash for any fractional shares of CVS/Caremark common stock that they otherwise would receive in the merger. The amount of cash for fractional shares will be calculated by multiplying the fraction of a share of CVS/Caremark common stock to which the Caremark stockholder would be entitled to receive in the merger by the closing sale price of a share of CVS/Caremark common stock on the first trading day immediately following the effective time of the merger. The CVS/Caremark common stock received based on the exchange ratio, together with any cash received in lieu of fractional shares, is referred to as the merger consideration. For more information about fractional share treatment, please see “The Merger Agreement—Fractional Shares” beginning on page 107 and for more information about the treatment of Caremark options, please see “The Merger Agreement—Caremark Stock Options” beginning on page 107.

         CVS Stockholders. CVS stockholders will continue to own their existing shares of CVS common stock and CVS ESOP preference stock after the merger. Each share of CVS common stock or CVS ESOP preference stock will represent one share of common stock or ESOP preference stock, respectively, in the combined company. CVS stockholders should not send in their stock certificates in connection with the merger.

    Ownership of the Combined Company After the Merger

         The combined company will issue approximately 712.4 million shares of CVS/Caremark common stock to Caremark stockholders in the merger based on the number of shares of Caremark common stock outstanding on January 15, 2007. At the completion of the merger, before giving effect to the accelerated repurchase share transaction described under “The Merger—Accelerated Share Repurchase Transaction” on page 40, it is expected that there will be outstanding approximately 1.56 billion shares of common stock of the combined company. The shares of CVS/Caremark common stock issued to Caremark stockholders in the merger will represent approximately 45.5% of the outstanding common stock of the combined company immediately after the merger on a fully diluted basis including shares reserved for issuance upon exercise of options and warrants. Shares of CVS/Caremark common stock held by CVS stockholders will represent approximately 54.5% of the outstanding common stock of the combined company immediately after the merger on a fully diluted basis.

    Caremark Special Cash Dividend

         On the date of Amendment No. 1 to the merger agreement, CVS separately granted a waiver to Caremark from the restrictions set forth in Section 6.01(b) of the merger agreement to permit Caremark to pay a one-time, special

    8






    cash dividend, which is referred to as the Caremark special cash dividend, to holders of record of Caremark common stock (on a record date to be set by the Caremark board of directors) in the amount of $2.00 per share of Caremark common stock held by each such holder on such record date, which dividend shall, under the terms of the CVS waiver, be declared prior to the Caremark special meeting, but shall only become payable upon or after the effective time of the merger, and such payment shall be conditioned upon the completion of the merger.

    Accelerated Share Repurchase Transaction

         The parties have agreed that as promptly as practicable after the closing of the merger, CVS/Caremark will execute an accelerated share repurchase transaction, which is referred to as the accelerated share repurchase transaction, on customary terms, whereby CVS/Caremark will retire 150 million shares of its common stock (approximately 9.8% of the combined company’s pro-forma outstanding shares after giving effect to the merger). To implement this transaction, CVS/Caremark will enter into an agreement with one or more financial institutions to purchase from each of them shares of common stock and pay each of them for the shares to be retired. The effect of this transaction and the related borrowing by the combined company to finance the transaction will be the immediate reduction of shares outstanding by 150 million shares and an increase in the combined company’s funded debt by approximately $4.8 billion. CVS has received commitments for such financing. It is anticipated that the agreement with the financial institutions will provide for a purchase price adjustment mechanism customary for such a transaction. The purchase price adjustment under such agreement may be subject to limits on the amounts that may be owed by CVS/Caremark or the financial institutions or both.

    Comparative Market Prices and Share Information (see page 24 and page 25)

         CVS common stock is listed on the NYSE under the symbol “CVS”. Caremark common stock is listed on the NYSE under the symbol “CMX”. The following table sets forth the closing sale prices of CVS common stock as reported on the NYSE and the closing sale prices of Caremark common stock as reported on the New York Stock Exchange, each on October 31, 2006, the last trading day before CVS and Caremark announced the transaction, and on January 12, 2007. This table also shows the implied value of a Caremark common share, which was calculated by multiplying the closing price of CVS common stock on those dates by the exchange ratio of 1.670.

        CVS Common Stock   Caremark Common Stock   Implied Value of Caremark Common
    Stock (a)



    October 31, 2006   $31.38   $49.23   $52.40
    January 12, 2007   $31.94   $56.83   $53.34

    (a) The implied value of Caremark common stock does not include the $2.00 per share special cash dividend.

         The market prices of CVS common stock and Caremark common stock will fluctuate before the special meetings and before the merger is completed. Therefore, you should obtain current market quotations for CVS common stock and Caremark common stock.

    Recommendations to Stockholders

         Recommendations to CVS Stockholders. The CVS board of directors has unanimously determined that the merger agreement and the merger and other transactions contemplated therein, including the issuance of CVS/Caremark common stock and the amendments to CVS’ charter are advisable and in the best interests of CVS and its stockholders.

UBS’ and JPMorgan’s opinions as to the fairness, from a financial point of view, of the exchange ratio were provided to the Caremark board of directors in connection with its evaluation of the exchange ratio from a financial point of view, do not address any other aspect of the merger and do not constitute a recommendation to any stockholder as to how to vote or act with respect to the merger.

    Treatment of Caremark Options (see page 107)

         Prior to the effective time of the merger, the compensation committee of the Caremark board of directors will make adjustments to Caremark’s outstanding stock options to reflect the Caremark special cash dividend. At the effective time of the merger, each outstanding option to purchase shares of Caremark common stock, which is referred to as a Caremark option, will be converted into an option to purchase shares of CVS/Caremark common stock on the same terms and conditions as were applicable before the merger except that each option will allow the holder thereof to purchase a number of shares of CVS/Caremark common stock equal to (1) the number of shares of Caremark common stock subject to the Caremark option before the completion of the merger multiplied by (2) 1.670, rounded down to the nearest whole share. In addition, at the effective time of the merger, each option to purchase shares of the combined company common stock will have an exercise price per share equal to (1) the aggregate exercise price required to purchase all shares of Caremark common stock subject to the Caremark option before the completion of the merger divided by (2) the number of shares of CVS/Caremark common stock subject to the option after completion of the merger, rounded up to the nearest whole cent.

    Interests of CVS’ and Caremark’s Executive Officers and Directors in the Merger (see pages 74 and 86)

         When you consider the CVS and Caremark board of directors’ respective recommendations that stockholders vote in favor of the proposals described in this document, you should be aware that (1) some Caremark executive officers and directors may have interests that may be different from, or in addition to, Caremark stockholders’ interests, including but not limited to, their receipt of severance benefits under existing Caremark employment arrangements, entry into employment arrangements with the combined company, accelerated vesting of Caremark options and participation in various benefits plans and (2) some CVS executive officers and directors may have interests that may be different from, or in addition to, CVS stockholders’ interests.

    No Appraisal or Dissenters’ Rights (see page 96)

         Under Delaware law, CVS and Caremark stockholders have no right to an appraisal of the value of their shares in connection with the merger.

    Material Federal Income Tax Consequences of the Caremark Special Cash Dividend and the Merger (see page 99)

         Tax Consequences of the Caremark Special Cash Dividend. Caremark and CVS intend to report the Caremark special cash dividend as a distribution with respect to Caremark common stock that will be taxable as dividend income to Caremark stockholders to the extent of Caremark’s earnings and profits as determined for U.S. federal income tax purposes. The tax treatment of the Caremark special cash dividend, however, is unclear and if the Caremark special cash dividend were treated for tax purposes as additional consideration received in connection with the merger, the amount of cash received by a Caremark stockholder would be taxable to such stockholder only to the extent of the gain realized by such stockholder in the merger.

         Tax Consequences of the Merger. A Caremark stockholder’s receipt of CVS/Caremark common stock in the merger will generally be tax-free for U.S. federal income tax purposes, except for taxes that may result from (i) any receipt of cash in lieu of a fractional share of CVS/Caremark common stock, and, (ii) if the Caremark special cash dividend were treated as additional consideration in connection with the Merger, gain recognized in respect of such additional consideration. There will be no U.S. federal income tax consequences to a holder of CVS common stock as a result of the Merger.

         The U.S. federal income tax consequences described above may not apply to some holders of Caremark common stock, including some types of holders specifically referred to on page 99. Accordingly, please consult your tax advisor for a full understanding of the particular tax consequences of the merger to you.

    Accounting Treatment (see page 95).

         CVS/Caremark will account for the merger under the purchase method of accounting for business transactions. In accordance with accounting principles generally accepted in the U.S., which is referred to as U.S. GAAP, CVS will be considered the acquiror of Caremark for accounting purposes.

    Regulatory Approvals (see page 102)

         The merger is subject to review by the U.S. Federal Trade Commission, the U.S. Department of Justice and state antitrust authorities pursuant to applicable federal and state antitrust laws. Under the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations thereunder, which is referred to as the HSR Act, the merger cannot be completed until the companies have made required notifications, given certain information and materials to the Federal Trade Commission and to the Antitrust Division of the U.S. Department of Justice and a required waiting period has expired or been terminated. CVS and Caremark filed the required notification and report forms with the Antitrust Division and the Federal Trade Commission on November 20, 2006. On December 20, 2006, the initial waiting period required under the HSR Act expired without a request for additional information from the Federal Trade Commission. CVS and Caremark have been informed that Arizona, California, Florida, Illinois, Louisiana, Maine, Massachusetts, Missouri, Nebraska, New York, Ohio,

    11






    Pennsylvania, Rhode Island, Virginia and the District of Columbia, the states that had previously indicated they would be reviewing the merger from an antitrust perspective, will not pursue their review of the proposed merger.

         As described further under “Risk Factors”, Caremark’s and CVS’ businesses are subject to numerous federal, state and local laws and regulations including, but not limited to, healthcare regulatory laws and regulations applicable to the following: the licensure and regulation of pharmacies and pharmacists and other healthcare professionals; Medicare, Medicaid and other government reimbursement programs; the Health Insurance Portability and Accountability Act, or HIPAA; the storage, advertisement, promotion, sale and distribution of controlled substances and other products; and the like. Certain of these healthcare regulatory laws and regulations may require filings or approvals in connection with the completion of the merger; however, it is not expected that (1) any such filings or approvals would delay the merger or (2) the failure to make any such filings or obtain any such approvals prior to the merger would have a material adverse effect on either of CVS or Caremark.

    Listing of CVS/Caremark Common Stock (see page 108)

         CVS has agreed to use its commercially reasonable efforts to cause the shares of CVS/Caremark common stock to be issued in the merger and the shares of CVS/Caremark common stock to be reserved for issuance upon exercise of the Caremark stock options and warrants to be approved for listing on the NYSE. It is also a condition to the merger that the shares of CVS/Caremark common stock issuable in the merger be approved for listing on the NYSE on or prior to the effective time of the merger.

    Conditions to Completion of the Merger (see page 114)

         CVS and Caremark will be required to complete the merger only if specific conditions, including the following, are satisfied or waived:

    • approval of (1) the amendment of the CVS charter to increase its authorized shares and (2) the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger, in each case, by the requisite vote of the CVS stockholders;

    • the adoption of the merger agreement and the approval of the merger by the requisite vote of the Caremark stockholders;

    • absence of any applicable law prohibiting or preventing the completion of the merger;

    • expiration or termination of the waiting period (and any extension thereof) applicable to the merger under the HSR Act;

    • the effectiveness of, and the absence of any stop order with respect to, the registration statement on Form S-4 of which this document forms a part;

    • approval for listing on the NYSE, subject to official notice of issuance, of the shares of CVS/Caremark common stock issuable in the merger to Caremark’s stockholders;

    • receipt of all required approvals of any governmental authority, subject to certain exceptions as described herein (see “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114);

    • absence of legal prohibitions issued or deemed applicable to the merger that would reasonably be expected to (1) materially and adversely diminish the benefits expected to be derived by the parties on the date of the merger agreement from the combination of CVS and Caremark via the merger (such combined business to be taken as a whole), in such a manner that either CVS or Caremark would not have entered into the merger agreement in the face of such materially and adversely diminished benefits, or (2) otherwise have a material adverse effect (see “The Merger Agreement—Representations and Warranties” beginning on page 108 for a definition of material adverse effect) after the effective time of the merger on CVS/Caremark and its subsidiaries, taken as a whole;

    12







    • CVS having taken all actions necessary to cause the amended charter and amended bylaws of the combined company to be effective at the effective time of the merger and to ensure that the CVS/Caremark board of directors is comprised in the manner contemplated by the merger agreement;

    • receipt of opinions of CVS’ and Caremark’s counsel that the merger will qualify as a tax-free reorganization;

    • the representations and warranties made by each party being true in all respects (but without regard to materiality qualifications or references to material adverse effect that may be contained in any representation or warranty) as of the effective time of the merger (except for representations and warranties expressly made as of a specific date, the accuracy of which will be determined as of such specified date), except where failure of such representations and warranties to be true would not reasonably be expected to have, whether individually or in the aggregate, a material adverse effect on the party making the representation or warranty; and

    • each party having performed in all material respects the obligations required to be performed by it at or before the effective time of the merger.

    Termination of the Merger Agreement (see page 115)

         The merger agreement may be terminated at any time before the effective time of the merger by mutual written consent of CVS and Caremark.

         The merger agreement may also be terminated prior to the effective time of the merger by either CVS or Caremark if:

    • the merger has not been completed by November 1, 2007, unless the only reason that the merger has not occurred by November 1, 2007 is that the waiting period applicable to the merger under the HSR Act has not expired or been terminated, in which case the termination date will be extended to May 1, 2008;

    • there is a permanent legal prohibition to completing the merger; or

    • Caremark stockholders or CVS stockholders fail to give the necessary approval at their special meetings or any adjournments or postponements thereof.

          The merger agreement may also be terminated prior to the effective time of the merger by CVS if:

    • the Caremark board of directors has made a change in recommendation (see “The Merger Agreement— Certain Covenants—No Solicitation” beginning on page 110);

    • there has been a willful or material breach by Caremark of its obligations under the no solicitation covenant in the merger agreement (see “The Merger Agreement—Certain Covenants—No Solicitation” beginning on page 110);

    • for any reason Caremark fails to call and hold a meeting of the Caremark stockholders to consider the adoption of the merger agreement and approval of the merger as required by the merger agreement; or

    • Caremark has breached any of its representations or warranties or failed to perform any of its covenants or agreements set forth in the merger agreement, if such breach or failure to perform would result in the failure to satisfy the closing condition of the merger relating to the accuracy of the representations and warranties or compliance with covenants contained in the merger agreement by November 1, 2007 (or, May 1, 2008, if extended as permitted in the merger agreement).

          The merger agreement may also be terminated prior to the effective time of the merger by Caremark if:

    13






    • there has been a willful or material breach by CVS of its obligations under the no solicitation covenant in the merger agreement (see “The Merger Agreement—Certain Covenants—No Solicitation” beginning on page 110);

    • for any reason CVS fails to call and hold a meeting of the CVS stockholders to consider the approval of the amendments to the CVS charter and the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger as required by the merger agreement; or

    • CVS has breached any of its representations or warranties or failed to perform any of its covenants or agreements set forth in the merger agreement, if such breach or failure to perform would result in the failure to satisfy the closing condition of the merger relating to the accuracy of the representations and warranties or compliance with covenants contained in the merger agreement by November 1, 2007 (or, May 1, 2008, if extended as permitted in the merger agreement).

    Termination Fees and Expenses (see page 116)

         Termination Fee Payable by CVS. CVS has agreed to pay a fee of $675 million to Caremark if the merger agreement is terminated under any of the following circumstances:

    • the CVS board of directors makes a change in recommendation;

    • CVS willfully and materially breaches certain obligations not to solicit acquisition proposals or fails to call a stockholders’ meeting to vote on the proposals to amend the CVS charter and issue CVS/Caremark common stock to Caremark stockholders in the merger; or

    • the merger is not consummated by November 1, 2007 (or, May 1, 2008, if extended as permitted in the merger agreement) or CVS’ stockholders fail to approve the proposals to amend the CVS charter and to issue CVS/Caremark common stock to Caremark stockholders in the merger, in each case, only if (1) a third party has made an acquisition proposal before the CVS special meeting and (2) within 12 months of the termination of the merger agreement, CVS enters into an alternative transaction.

         Termination Fee Payable by Caremark. Caremark has agreed to pay a fee of $675 million to CVS if the merger agreement is terminated under any of the following circumstances:

    14





         Certain current executive officers of CVS and Caremark will have executive officer positions with the combined company after the merger.

    Governance After the Merger (see page 128)

         In connection with the merger, the parties have reached certain agreements regarding the governance of CVS/Caremark, including the following:

    • After the merger, the board of directors of the combined company will be comprised of an equal number of directors to be selected by each of CVS and Caremark. Commencing with the first annual meeting of CVS/Caremark stockholders after the effective time of the merger, composition of the CVS/Caremark board of directors and its committees will be determined by the nomination and election process provided for in the amended CVS charter, amended CVS bylaws and Delaware law.

    • The CVS/Caremark board of directors will have a standing audit committee; management, planning and development committee; nominating and corporate governance committee and executive committee. At the effective time of the merger, the chairman of the CVS/Caremark audit committee will be selected by the members of the CVS/Caremark board of directors designated by Caremark and the chairman of each of the management, planning and development committee and the nominating and corporate governance committee will be selected by the members of the CVS/Caremark board of directors designated by CVS.

    • At the effective time of the merger, the executive committee of the CVS/Caremark board of directors will consist of four directors: the chairman of the combined company’s board of directors, its chief executive officer, one director selected by the members of the CVS/Caremark board of directors designated by CVS and one director selected by the members of the CVS/Caremark board of directors designated by Caremark.

    • Prior to the first annual meeting of CVS/Caremark stockholders after the effective time of the merger a director designated to the CVS/Caremark board of directors by CVS, referred to as a CVS-designated director, may only be removed by a majority vote of the other CVS-designated directors, and any vacancy on the CVS/Caremark board of directors resulting from the death, removal or resignation of any CVS- designated director may only be filled by the remaining CVS-designated directors.

    • Prior to the first annual meeting of CVS/Caremark stockholders after the effective time of the merger, a director designated to the CVS/Caremark board of directors by Caremark, referred to as a Caremark- designated director, may only be removed by a majority vote of the other Caremark-designated directors, and any vacancy on the CVS/Caremark board of directors resulting from the death, removal or resignation of any Caremark-designated director may only be filled by the remaining Caremark-designated directors.

    CVS Bylaws Amendment (see page 128)

         In connection with entering into the merger agreement, the CVS board of directors approved amendments to the CVS bylaws, which will become effective only upon the effective time of the merger. The amendments to the CVS bylaws will:

    • any amendment to the provisions of the bylaws with respect to the two immediately preceding bullets or the provisions of the bylaws giving effect to the matters described above under “—Governance After the Merger”.

    Special Meetings of CVS and Caremark Stockholders

    CVS Special Meeting (see page 118)

         Meeting. The CVS special meeting will be held on February 23, 2007, at 11:00 a.m., Eastern Time, at CVS’ corporate headquarters, One CVS Drive, Woonsocket, Rhode Island 02895. At the CVS special meeting, CVS stockholders will be asked:

    • to approve the amendments of the CVS charter, effective upon completion of the merger, to increase the authorized number of shares of CVS common stock from 1 billion to 3.2 billion shares and to change CVS’ name to “CVS/Caremark Corporation”;

    • to approve the issuance of CVS/Caremark common stock to Caremark stockholders in the merger; and

    • to approve an adjournment or postponement of the special meeting, including if necessary, to solicit additional proxies in favor of the foregoing proposals.

         Record Date; Votes. CVS has fixed the close of business on January 19, 2007 as the record date, which is referred to as the CVS record date, for determining the CVS stockholders entitled to receive notice of and to vote at the CVS special meeting. Only holders of record of CVS common stock and CVS ESOP preference stock on the CVS record date are entitled to receive notice of and vote at the CVS special meeting, and any adjournment or postponement thereof.

         Each share of CVS common stock is entitled to one vote and each share of CVS ESOP preference stock is entitled to the number of votes equal to the number of shares of CVS common stock into which that share of CVS ESOP preference stock is entitled to be converted on the CVS record date, rounded up to the nearest tenth of a share. Each share of CVS ESOP preference stock is currently entitled to 4.6 votes at the CVS special meeting (subject to adjustment before the CVS special meeting in the case of certain dilutive events). On the CVS record date, there were approximately 826,911,756 shares of CVS common stock and approximately 3,990,277 shares of CVS ESOP preference stock (representing approximately 18,355,274 votes in the aggregate) entitled to vote at the CVS special meeting.

          Required Vote. The CVS proposals require different percentages of votes for approval:

    • the approval of the amendments of the CVS charter requires the affirmative vote of at least a majority of the votes represented by the outstanding CVS common stock and CVS ESOP preference stock entitled to vote at the CVS special meeting, voting together as a single class;

    • the approval of the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger requires the affirmative vote of holders of CVS common stock and CVS ESOP preference stock, voting together as a single class, representing a majority of the votes cast in person or represented by proxy at the CVS special meeting, provided that the total number of votes cast on the proposal represents over 50% of the total number of votes of the CVS common stock and CVS ESOP preference stock entitled to be cast at the CVS special meeting; and

    16






    • the approval of an adjournment or postponement of the CVS special meeting, including, if necessary, to solicit additional proxies if there are not sufficient votes for each of the foregoing proposals, requires the affirmative vote of holders of CVS common stock and CVS ESOP preference stock, voting together as a single class, representing a majority of the votes cast in person or represented by proxy at the CVS special meeting and entitled to vote on the proposal.

         Each of the first two proposals listed above relating to the merger (i.e., the amendments of the CVS charter and the CVS/Caremark common stock issuance) are conditioned on one another and the approval of each of these proposals is a condition to completion of the merger. Neither the amendments of the CVS charter nor the issuance of CVS/Caremark common stock in the merger will take place unless both of these proposals are approved by the CVS stockholders and the merger is completed. Therefore, the completion of the merger cannot proceed without the approval of both proposals.

         Failure to Vote; Abstentions. If you abstain from voting on the proposal to amend the CVS charter or the proposal to adjourn or postpone the meeting it will have the same effect as a vote “AGAINST” that proposal. If you abstain from voting on the proposal to issue shares of CVS/Caremark common stock, the abstention will have no effect in determining the outcome of the vote, assuming a quorum is present. If you fail to vote your CVS common stock, including broker non-votes, (1) on the proposal to amend the CVS charter it will have the same effect as a vote “AGAINST” that proposal and (2) on either the proposal to issue CVS/Caremark common stock in the merger or to adjourn or postpone the CVS special meeting, it will have no effect in determining the outcome of the applicable vote. For more information regarding the effect of abstentions, a failure to vote or broker non-votes, see “The CVS Special Meeting—Votes Required to Approve CVS Proposals” beginning on page 120.

         Each participant in the CVS Plan instructs the trustee of the CVS Plan how to vote his or her shares of (1) CVS ESOP preference stock and (2) CVS common stock held in the CVS Plan. Unallocated shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan and shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan for which no voting instruction is timely received by the trustee of the CVS Plan will be voted by such trustee in the same proportion as such trustee votes all the shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan as to which it has received timely voting instructions.

         Revocation of Proxies. You have the power to revoke your proxy at any time before the proxy is voted at the CVS special meeting. You can revoke your proxy in one of four ways:

    • you can send a signed notice of revocation;

    • you can grant a new, valid proxy bearing a later date;

    • you can revoke the proxy in accordance with the telephone or Internet voting procedures described in the proxy voting instructions attached to the proxy card; or

    • if you are a holder of record, you can attend the CVS special meeting and vote in person which will automatically cancel any proxy previously given, but your attendance alone will not revoke any proxy that you have previously given.

         If you choose either of the first two methods, you must submit your notice of revocation or your new proxy to CVS’ Corporate Secretary at the CVS address under “The Companies” beginning on page 104 no later than the beginning of the CVS special meeting.

         Stock Ownership of CVS Directors and Executive Officers. On January 19, 2007, the CVS record date, directors and executive officers of CVS and their respective affiliates owned and were entitled to vote approximately 1,181,972 shares of CVS common stock, or approximately 0.14% of the shares of CVS common stock outstanding on that date. To CVS’ knowledge, the directors and executive officers of CVS and their respective affiliates intend to vote their shares of CVS common stock in favor of all CVS proposals at the CVS special meeting.

    17






    Caremark Special Meeting (see page 123)

         Meeting. The Caremark special meeting will be held on February 20, 2007, at 1:00 p.m., Central Time, at the Hilton Nashville Downtown at 121 Fourth Avenue South, Nashville, Tennessee 37201. At the Caremark special meeting, Caremark stockholders will be asked:

    • to adopt the merger agreement and approve the merger, pursuant to which Caremark will become a wholly owned subsidiary of CVS; and

    • to approve an adjournment or postponement of the Caremark special meeting, including if necessary, to solicit additional proxies in favor of the adoption of the merger agreement and approval of the merger if there are not sufficient votes for such proposal.

         Record Date; Votes. Caremark has fixed the close of business on January 15, 2007 as the record date, which is referred to as the Caremark record date, for determining the Caremark stockholders entitled to receive notice of and to vote at the Caremark special meeting. Only holders of record of Caremark common stock on the Caremark record date are entitled to receive notice of and vote at the Caremark special meeting, and any adjournment or postponement thereof.

         Each share of Caremark common stock is entitled to one vote. On the Caremark record date, there were 426,570,418 shares of Caremark common stock entitled to vote at the Caremark special meeting.

          Required Vote. The proposals require different percentages of votes in order to approve them:

    • The adoption of the merger agreement and the approval of the merger require the affirmative vote of holders of a majority of the outstanding shares of Caremark common stock entitled to vote at the Caremark special meeting.

    • The approval of an adjournment or postponement of the Caremark special meeting, including if necessary, to solicit additional proxies in favor of such adoption and approval requires the affirmative vote of holders of Caremark common stock representing a majority of the voting power of such shares present in person or represented by proxy at the Caremark special meeting and entitled to vote on the proposal.

    Adoption of the merger agreement and approval of the merger by Caremark stockholders is a condition to completion of the merger.

         Failure to Vote; Abstentions. If you abstain from voting on any proposal it will have the same effect as a vote “AGAINST” that proposal. If you fail to vote, including broker non-votes, (1) on the proposal to adopt the merger agreement and approve the merger, it will have the same effect as a vote “AGAINST” that proposal and (2) on the proposal to adjourn or postpone the Caremark special meeting, it will have no effect in determining the outcome of the applicable vote. For more information regarding the effect of abstentions, a failure to vote or broker non-votes, see “The Caremark Special Meeting—Votes Required to Approve Caremark Proposals” beginning on page 124.

         Revocation of Proxies. You have the power to revoke your proxy at any time before the proxy is voted at the Caremark special meeting. You can revoke your proxy in one of four ways:

    • you can send a signed notice of revocation;

    • you can grant a new, valid proxy bearing a later date;

    • you can revoke the proxy in accordance with the telephone or Internet voting procedures described in the proxy voting instructions attached to the proxy card; or

    • if you are a holder of record, you can attend the Caremark special meeting and vote in person which will automatically cancel any proxy previously given, but your attendance alone will not revoke any proxy that you have previously given.

    18





         If you choose either of the first two methods, you must submit your notice of revocation or your new proxy to Caremark’s Corporate Secretary at the Caremark address under “The Companies” beginning on page 104 no later than the beginning of the Caremark special meeting.

         Stock Ownership of Directors and Executive Officers. On January 15, 2007, the Caremark record date, directors and executive officers of Caremark and their respective affiliates owned and were entitled to vote 449,201 shares of Caremark common stock, or less than 1 % of the shares of Caremark common stock outstanding on that date. To Caremark’s knowledge, the directors and executive officers of Caremark and their respective affiliates intend to vote their shares of Caremark common stock in favor of both Caremark proposals at the Caremark special meeting.

    (1) Gross profit includes the pre-tax effect of $5.7 million ($3.6 million after-tax) non-recurring charge in 2001 related to the markdown of certain inventory contained in the stores as part of a strategic restructuring program.
       
    (2) In 2004, CVS conformed its accounting for operating leases and leasehold improvements to the views expressed by the Office of the Chief Accountant of the Securities and Exchange Commission to the American Institute of Certified Public Accountants on February 7, 2005. As a result, CVS recorded a non-cash pre-tax adjustment of $9.0 million ($5.4 million after-tax) to selling, general and administrative expenses and $56.9 million ($35.1 million after tax) to depreciation and amortization, which represents the cumulative effect of the adjustment for a period of approximately 20 years. Since the effect of this non-cash adjustment was not material to any previously reported fiscal year, the cumulative effect was recorded in the fourth quarter of 2004.
       
    (3) As a result of adopting SFAS No. 142, “Goodwill and Other Intangible Assets” at the beginning of fiscal 2002, CVS no longer amortizes goodwill and other indefinite-lived intangible assets. Goodwill amortization totaled $31.4 million pre-tax ($28.2 million after-tax) in 2001.
       
    (4) Operating profit includes the pre-tax effect of the charges discussed in Note (1) above and the following merger, restructuring, and other nonrecurring charges and gains: (i) in 2004, $65.9 million ($40.5 million after-tax) relating to conforming CVS’ accounting for operating leases and leasehold improvements and (ii) in 2001, $346.8 million ($226.9 million after-tax) related to restructuring and asset impairment

    20






      costs associated with the strategic restructuring and $3.5 million ($2.1 million after-tax) non-recurring gain resulting from the net effect of the $50.3 million of settlement proceeds received from various lawsuits against certain manufacturers of brand name prescription drugs which was offset by our contribution of $46.8 million of these settlement proceeds to the CVS Charitable Trust, Inc. to fund future charitable giving.
       
    (5) Income tax provision includes the effect of the following: (i) in 2005, a $52.6 million reversal of previously recorded tax reserves through the tax provision principally based on resolving certain state tax matters, and (ii) in 2004, a $60.0 million reversal of previously recorded tax reserves through the tax provision principally based on finalizing certain tax return years and on a 2004 court decision relevant to the industry.
       
    (6) Net earnings and net earnings per common share include the after-tax effect of the charges and gains discussed in Notes (1), (2), (3), (4) and (5) above.
       
    (7) On May 12, 2005, the CVS board of directors authorized a two-for-one common stock split, which was effected in the form of a dividend by the issuance of one additional share of CVS common stock for each share of CVS common stock outstanding. These shares were distributed on June 6, 2005 to stockholders of record as of May 23, 2005. All prior periods have been restated to reflect the effect of the two-for-one stock split.

The selected consolidated financial and operating data as of and for the fiscal years ended December 31, 2005, 2004, 2003, 2002 and 2001 have been derived from Caremark’s consolidated financial statements. You should not take historical results as necessarily indicative of the results that may be expected for any future period. The selected consolidated financial and operating data as of and for the nine months ended September 30, 2006 and 2005 have been derived from Caremark’s unaudited consolidated condensed financial statements. The results for the nine months ended September 30, 2006 are not necessarily indicative of results that may be expected for the entire fiscal year.

         You should read this selected consolidated financial and operating data in conjunction with Caremark’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and Caremark’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2006.

    (1) The 2002 period includes amounts related to adjustments to the deferred income tax asset valuation allowance. This adjustment resulted in the recognition of: (i) a $520 million deferred tax benefit included in income from continuing operations and related statement of operations and per common share line items; (ii) a $615 million deferred tax asset included in total assets; and (iii) a direct increase to stockholder’s equity of approximately $69.5 million.
       
    (2) The December 31, 2005 long-term debt (net of current portion) reflects the classification of $386.6 million of 7.375% senior notes due 2006 as long-term debt due to Caremark’s intent and ability to refinance this amount on a long-term basis at the time of filing its Annual Report on Form 10-K. The amount classified as long-term debt (net of current portion) was limited to Caremark’s availability under its revolving credit facility, and the remaining $63.4 million of its 7.375% senior notes were classified as a current liability. Caremark ultimately did not refinance these notes and repaid them using cash on hand when they matured in October 2006. The December 31, 2004 long-term debt (net of current portion) amount excludes Caremark’s $147 million term loan which was repaid on February 18, 2005, and the repurchase of remaining senior notes of a recently acquired business at 104.25% of face value on April 1, 2005.
       
    (3) Caremark acquired AdvancePCS on March 24, 2004. The Statement of Operations data includes the results of operations of AdvancePCS beginning March 24, 2004. The Statement of Operations, Per Common Share and Balance Sheet data were significantly impacted by the AdvancePCS acquisition.

    SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA

         The following unaudited pro forma statements of operations data for the year ended December 31, 2005 and the nine months ended September 30, 2006 reflect the merger as if it had occurred on the first day of each period presented. The following unaudited pro forma balance sheet data at September 30, 2006 reflect the merger as if it had occurred on that date. Such pro forma financial data is based on the historical financial statements of CVS and Caremark and gives effect to the merger under the purchase method of accounting for business combinations as well as the acquisition CVS completed on June 2, 2006. As a result, the pro forma financial information is based on certain assumptions and adjustments as discussed in the section titled “Unaudited Pro Forma Condensed Combined Financial Information”, including assumptions relating to the consideration paid and the allocation thereof for the assets and liabilities of Caremark based on preliminary estimates of their fair value. In addition, the pro forma financial information does not reflect the payment of the Caremark special cash dividend discussed in “The Merger—Special Cash Dividend” beginning on page 40.

         The table below sets forth the closing sale prices of CVS common stock and Caremark common stock as reported on the NYSE each on October 31, 2006, the last trading day prior to the public announcement of the transaction, and on January 12, 2007. The table also shows the implied value of one Caremark common share, which was calculated by multiplying the closing price of CVS common stock on those dates and the exchange ratio of 1.670. The market prices of CVS and Caremark common stock on those dates will fluctuate between the date of this document and the time of the special meetings and the completion of the merger. No assurance can be given concerning the market prices of CVS common stock or Caremark common stock before the completion of the merger or the market price of CVS/Caremark common stock after the completion of the merger. The exchange ratio is fixed in the merger agreement. One result of this is that the market value of the CVS/Caremark common stock that Caremark stockholders will receive in the merger may vary significantly from the prices shown in the table below.

    (a)   The implied value of Caremark common stock does not inclulde the $2.00 per share special cash dividend

         Caremark stockholders should obtain current market quotations for shares of CVS common stock and Caremark common stock in deciding whether to vote for adoption of the merger agreement and approval of the merger. CVS stockholders should obtain current market quotations for shares of CVS and Caremark common stock in deciding whether to vote for approval of the issuance of CVS/Caremark common stock to Caremark stockholders in the merger and the amendments of the CVS charter to increase the number of authorized shares and change the name of the corporation to CVS/Caremark.

         Pursuant to the merger agreement, CVS and Caremark are permitted to pay to holders of their respective shares of common stock, before the effective time of the merger, regular quarterly cash dividends. However, CVS and Caremark have also agreed to coordinate the declaration of dividends prior to the effective time of the merger so that the holders of CVS common stock and holders of Caremark common stock do not receive, in any quarter, more than or less than one dividend in respect of those shares held prior to the effective time of the merger and those shares of CVS/Caremark issued in the merger. In addition, as previously discussed, Caremark stockholders will receive a one-time special cash dividend in the amount of $2.00 per share of Caremark common stock held by each such holder on a record date to be set by the Caremark board of directors, which dividend will be conditioned on completion of the merger and will be paid at or immediately following the effective time of the merger. After the effective time of the merger, CVS and Caremark expect that the combined company will continue to pay quarterly dividends to stockholders of the combined company at an annual dividend rate per share of CVS/Caremark common stock of $0.24. This is higher than the current annual dividend payment on shares of CVS common stock and approximately equal to the current annual dividend of $0.40 on shares of Caremark common stock. The combined company’s payment of dividends in the future, however, will depend on business conditions, its financial condition and earnings, and other factors and there can be no guarantee that any dividends will be paid by the combined company.

    RISK FACTORS

         In addition to the other information included and incorporated by reference into this document, including the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements” below, you should carefully consider the following risk factors before deciding whether to vote for adoption of the merger agreement and approval of the merger, in the case of Caremark stockholders, or for the issuance of shares of CVS/Caremark common stock and the amendments to the CVS charter, in the case of CVS stockholders. In addition to the risk factors set forth below, you should read and consider other risk factors specific to each of the CVS and Caremark businesses that will also affect the combined company after the merger, described in Part I, Item 1A of each company’s annual report on Form 10-K for the year ended December 31, 2005, and Part II, Item 1A of Caremark’s quarterly report on Form 10-Q for the quarter ended September 30, 2006, each of which has been filed by CVS or Caremark, as applicable, with the SEC and all of which are incorporated by reference into this document. If any of the risks described below or in the periodic reports incorporated by reference into this document actually occurs, the respective businesses, financial results, financial condition, operating results or stock prices of CVS, Caremark or CVS/Caremark could be materially adversely affected. See “Where You Can Find More Information”, beginning on page 158.

    Risks Related to the Merger

     

    The exchange ratio is fixed and will not be adjusted. The market price of shares of CVS common stock may fluctuate, and Caremark stockholders cannot be sure of the market value of the shares of CVS/Caremark common stock that will be issued in the merger.

         Upon completion of the merger, each share of Caremark common stock outstanding immediately prior to the merger will be converted into the right to receive 1.670 shares of CVS/Caremark common stock. The exchange ratio is fixed at 1.670 shares of CVS/Caremark common stock for each share of Caremark common stock, and will not be adjusted due to any increases or decreases in the price of CVS common stock or Caremark common stock. The value of Caremark common stock in the merger will depend upon the market price of a share of CVS/Caremark common stock upon the completion of the merger. If the price of CVS common stock declines, Caremark stockholders will receive less value for their shares upon completion of the merger than the value calculated pursuant to the exchange ratio on the date the merger agreement was signed or on the date of the Caremark special meeting.

         The merger may not be completed until a significant period of time has passed after the CVS and Caremark special meetings, during which time the market value of CVS common stock and Caremark common stock will fluctuate. Therefore, at the time of their respective special meetings, CVS and Caremark stockholders will not know the exact market value of CVS/Caremark common stock that will be issued in connection with the merger. The market price of a share of CVS common stock at the time the merger is completed is likely to be different, and may be lower, than it was at the time the merger agreement was signed and at the time of the special meetings. The closing price of CVS common stock on the NYSE on October 31, 2006 was $31.38 per share. From November 1, 2006 through the date of this document, the trading price of CVS common stock ranged from a high of $31.99 per share to a low of $27.09 per share. For CVS and Caremark historical market prices, see “Comparative Per Share Market Price and Dividend Information” beginning on page 25.

          Stock price changes may result from a variety of factors, including, but not limited to:

    • changes in the business, operations or prospects of CVS or Caremark;

    • catastrophic events, both natural and man-made;

    • government, litigation and/or regulatory developments or considerations;

    • general market and economic conditions;

    27






    • market assessments as to whether and when the merger will be consummated and market assessments of the condition, results or prospects of either company’s business; and

    • governmental actions or legislative developments affecting the retail pharmacy, pharmacy benefits management, or pharmaceutical services or healthcare industry generally.

         Stockholders of CVS and Caremark are urged to obtain market quotations for CVS and Caremark common stock when they consider whether to approve the proposals required to complete the merger at the respective special meetings.

     

    The combined company may be unable to successfully integrate CVS’ and Caremark’s operations or to realize the anticipated cost savings and other benefits of the merger. As a result, the value of CVS/Caremark common stock may be adversely affected.

         CVS and Caremark entered into the merger agreement because each company believes that the merger will be beneficial to each of CVS, Caremark and their respective stockholders. Currently, each company operates as an independent public company. Achieving the anticipated benefits of the merger will depend in part upon whether the two companies integrate their businesses in an efficient and effective manner. The companies may not be able to accomplish this integration process smoothly or successfully. The necessity of coordinating geographically separated organizations, systems and facilities and addressing possible differences in business backgrounds, corporate cultures and management philosophies may increase the difficulties of integration. The companies operate numerous systems, including those involving management information, purchasing, accounting and finance, sales, billing, employee benefits, payroll and regulatory compliance. The integration of certain operations following the merger will require the dedication of significant management resources, which may temporarily distract management’s attention from the day-to-day business of the combined company. Employee uncertainty and lack of focus during the integration process may also disrupt the business of the combined company. Any inability of management to integrate successfully the operations of the two companies could have a material adverse effect on the business and results of operations of the combined company. The companies may not be able to achieve the anticipated operating and cost synergies or long-term strategic benefits of the merger. An inability to realize the full extent of, or any of, the anticipated benefits of the merger, as well as any delays encountered in the integration process, could have an adverse effect on the business and results of operations of the combined company, which may affect the value of the shares of CVS/Caremark common stock after the completion of the merger.

         The success of the combined company after the merger will depend in part upon the ability of CVS and Caremark to retain key employees of both companies. Competition for qualified personnel can be very intense. In addition, key employees may depart because of issues relating to the uncertainty or difficulty of integration or a desire not to remain with the combined company. Accordingly, no assurance can be given that CVS or Caremark will be able to retain key employees.

         Due to legal restrictions, Caremark and CVS have been able to conduct only limited planning regarding the integration of the two companies following the merger and have not yet determined the exact nature of how the businesses and operations of the two companies will be combined after the merger. The actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized.

     

    CVS/Caremark common stock may be affected by factors different from those affecting the price of Caremark common stock or CVS common stock.

         On completion of the merger, holders of Caremark common stock and CVS common stock will become holders of CVS/Caremark common stock. As the business of CVS and the business of Caremark are different, the results of operations as well as the price of CVS/Caremark common stock may be affected by factors different than those factors affecting CVS and Caremark as independent stand-alone entities. The combined company will face additional risks and uncertainties not otherwise facing each independent company in the merger. For a discussion of CVS’ and Caremark’s businesses and certain factors to consider in connection with their respective businesses, see “—Risks Related to CVS, Caremark and the Combined Company”, as well as the respective sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in each of CVS’ and

    28






    Caremark’s annual reports on Form 10-K for the year ended December 31, 2005, the CVS quarterly reports on Form 10-Q for the periods ended April 1, 2006, July 1, 2006 and September 30, 2006, the Caremark quarterly reports on Form 10-Q for the periods ended March 31, 2006, June 30, 2006 and September 30, 2006 and other documents incorporated by reference into this document.

     

    The merger may not be accretive and may cause dilution to CVS/Caremark earnings per share, which may harm the market price of the CVS/Caremark common stock.

         The parties currently anticipate that the merger will be accretive to earnings per share during the first full calendar year after the merger. However, due to legal restrictions, Caremark and CVS have been able to conduct only limited planning regarding the integration of the two companies. Accordingly, this expectation is based on preliminary estimates which may materially change after the completion of the merger. The combined company could also encounter additional transaction and integration-related costs or other factors such as the failure to realize all of the benefits anticipated in the merger. All of these factors could cause dilution to CVS/Caremark’s earnings per share or decrease the expected accretive effect of the merger and cause a decrease in the price of CVS/Caremark common stock.

     

    Failure to complete the merger could negatively impact the stock prices and the future business and financial results of CVS and Caremark.

         If the merger is not completed, the ongoing businesses of CVS or Caremark may be adversely affected and CVS and Caremark will be subject to several risks, including the following:

    • being required, under certain circumstances under the merger agreement, to pay a termination fee of $675 million to the other party (see “The Merger Agreement—Termination Fees” beginning on page 116);

    • having to pay certain costs relating to the merger;

    • the attention of management of CVS and Caremark will have been diverted to the merger instead of on such company’s own operations and pursuit of other opportunities that could have been beneficial to such company; and

    • customer perception may be negatively impacted which could affect the ability of CVS and Caremark to compete for, or to win, new and renewal business in the marketplace.
     

    Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market value of CVS/Caremark common stock following the merger.

         In accordance with U.S. GAAP, CVS will be considered the acquiror of Caremark for accounting purposes. CVS will account for the merger using the purchase method of accounting, which will result in charges to CVS/Caremark’s earnings that could adversely affect the market value of CVS/Caremark common stock following the completion of the merger. Under the purchase method of accounting, CVS will allocate the total purchase price to the assets acquired and liabilities assumed from Caremark based on their fair values as of the date of the completion of the merger, and record any excess of the purchase price over those fair values as goodwill. For certain tangible and intangible assets, reevaluating their fair values as of the completion date of the merger will result in CVS/Caremark’s incurring additional depreciation and/or amortization expense that exceed the combined amounts recorded by CVS and Caremark prior to the merger. This increased expense will be recorded by CVS/Caremark over the useful lives of the underlying assets. In addition, to the extent the value of goodwill or intangible assets were to become impaired, CVS/Caremark may be required to incur charges relating to the impairment of those assets. See “The Merger—Accounting Treatment” beginning on page 95.

    29






     

    CVS and Caremark must obtain governmental and regulatory consents to complete the merger, which, if delayed, not granted or granted with unacceptable conditions, may jeopardize or delay the completion of the merger, result in additional expenditures of money and resources and/or reduce the anticipated benefits of the merger.

         Completion of the merger is conditioned on the receipt of all material governmental authorizations, consents, orders and approvals, including the expiration or termination of the applicable waiting periods under the HSR Act and any required approvals of applicable insurance regulatory agencies in connection with the merger. CVS and Caremark intend to pursue all required approvals in accordance with the merger agreement. If the companies do not receive these approvals, or do not receive them on terms that satisfy the conditions set forth in the merger agreement, then neither company will be obligated to complete the merger. On December 20, 2006, the initial waiting period required under the HSR Act expired without a request for additional information from the Federal Trade Commission.

         The governmental agencies from which the companies will seek these approvals have broad discretion in administering the governing regulations. As a condition to approval of the merger, agencies may impose requirements, limitations or costs or require divestitures or place restrictions on the conduct of the combined company’s business. These requirements, limitations, costs, divestitures or restrictions could jeopardize or delay the completion of the merger or may reduce the anticipated benefits of the merger. Further, no assurance can be given that the required consents and approvals will be obtained or that the required conditions to closing will be satisfied, and, if all required consents and approvals are obtained and the conditions to the completion of the merger are satisfied, no assurance can be given as to the terms, conditions and timing of the approvals. If CVS and Caremark agree to any material requirements, limitations, costs, divestitures or restrictions in order to obtain any approvals required to complete the merger, these requirements, limitations, additional costs or restrictions could adversely affect the two companies’ ability to integrate their operations or reduce the anticipated benefits of the merger. This could result in a failure to complete the merger or have a material adverse effect on the business and results of operations of the combined company. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114 for a discussion of the conditions to the completion of the merger and “Regulatory and Other Approvals Required for the Merger” beginning on page 102 for a description of the regulatory approvals necessary in connection with the merger.

     

    The combined company will incur significant transaction and merger-related costs in connection with the merger.

         CVS and Caremark expect to incur a number of non-recurring costs associated with combining the operations of the two companies. The substantial majority of non-recurring expenses resulting from the merger will be comprised of transaction costs related to the merger, facilities and systems consolidation costs and employment–related costs. CVS and Caremark will also incur transaction fees and costs related to formulating integration plans. Additional unanticipated costs may be incurred in the integration of the two companies’ businesses. Due to legal restrictions, Caremark and CVS have been able to conduct only limited planning regarding the integration of the two companies and have not yet been able to formulate detailed integration plans to deliver anticipated synergies. Although CVS and Caremark expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses should allow them to offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

     

    Whether or not the merger is completed, the announcement and pendency of the merger could impact or cause disruptions in Caremark’s and CVS’ businesses, which could have an adverse effect on their results of operations and financial condition.

          Specifically:

    • current and prospective clients of PharmaCare (CVS’ PBM) and Caremark may experience uncertainty associated with the merger, including with respect to current or future business relationships with PharmaCare, Caremark or the combined company and may attempt to negotiate changes in existing

    30






      business relationships or consider entering into business relationships with parties other than PharmaCare,Caremark or the combined company, either before or after completion of the merger;

    • Caremark and CVS employees may experience uncertainty about their future roles with the combined company, which might adversely affect Caremark’s and CVS’ ability to retain and hire key managers and other employees;

    • if the merger is completed, the accelerated vesting of most stock options and availability of certain other “change in control” benefits to Caremark’s officers and employees on completion of the merger could result in increased difficulty or cost in retaining Caremark officers and employees;

    • the attention of management of each of Caremark and CVS may be directed toward the completion of the merger and transaction-related considerations and may be diverted from the day-to-day business operations of their respective companies; and

    • pharmaceutical manufacturers, retail pharmacies, pharmacy benefit management companies or other vendors or suppliers may seek to modify or terminate their business relationships with CVS or Caremark.

         Approximately one third of a PBM’s customer base typically is subject to renewal each year, and therefore Caremark and CVS may face additional challenges in competing for new business and retaining or renewing business. Caremark’s largest client, the Federal Employees Health Benefits Plan, is currently subject to renewal for services beginning January 1, 2008. There can be no assurance that Caremark will be able to secure renewal of this business; however, such renewal is not a condition to the completion of the merger. These disruptions could be exacerbated by a delay in the completion of the merger or termination of the merger agreement and could have an adverse effect on the businesses, financial condition, results of operations or prospects of Caremark and CVS if the merger is not completed or of the combined company if the merger is completed.

     

    Certain directors and executive officers of CVS and Caremark have interests that are different from, or in addition to, interests of CVS and Caremark stockholders generally.

         Some of the directors of Caremark who recommend that Caremark stockholders vote in favor of adopting the merger agreement, and the executive officers of Caremark who provided information to the Caremark board of directors relating to the merger, have employment, indemnification and severance benefit arrangements, rights to acceleration of stock options and other benefits on a change in control of Caremark and rights to ongoing indemnification and insurance that provide them with interests in the merger that may differ from Caremark stockholders generally. The receipt of compensation or other benefits, including the rights to acceleration of stock options referred to above by Caremark’s executive officers in connection with the merger, may make it more difficult for the combined company to retain their services after the merger, or require the combined company to expend additional sums to continue to retain their services. Caremark stockholders should be aware of these interests when considering the Caremark board of directors’ recommendation that they vote in favor of adopting the merger agreement and approving the merger. See “Interests of Caremark Executive Officers and Directors in the Merger” beginning on page 86.

         In addition, under the bylaws of CVS to be amended in connection with the merger, a vote of three-quarters of the combined company’s board of directors will be required to remove Mr. Thomas M. Ryan as its chief executive officer before January 2010. CVS stockholders should be aware of this interest when considering the CVS board of directors’ recommendation that they vote in favor of the proposals relating to the merger. See “Interests of CVS Executive Officers and Directors in the Merger” beginning on page 74.

    Risks Related to CVS, Caremark and the Combined Company

     

    The industries in which CVS and Caremark operate are extremely competitive and competition could adversely affect the combined company’s business and results of operations following the merger.

         CVS currently operates in a highly competitive environment. CVS competes, and after the completion of the merger, the combined company will compete, with other drugstore chains, supermarkets, discount retailers,

    31






    membership clubs and Internet companies. The combined company will continue to face competition from other mail order pharmacies and PBMs.

         The pharmacy benefits management industry in which Caremark and, to a lesser extent, CVS through PharmaCare, operate is extremely competitive. Competitors in the pharmacy benefits management industry include large national pharmacy benefit management companies, such as Medco Health Solutions, Inc. and Express Scripts, Inc., as well as many local or regional PBMs. In addition, there are several large health insurers and managed care plans (e.g., Wellpoint, Aetna, CIGNA, United Healthcare) and retail pharmacies (e.g., Walgreens, Longs and Rite-Aid) which have their own PBM capabilities as well as several other national and regional companies that provide some or all of the same services. Some of these competitors may offer services and pricing terms that the combined company, even if the anticipated benefits of the merger are realized in full, may not be able to offer. In addition, competition may also come from other sources in the future. As a result, competition could have an adverse effect on its business and results of operations.

     

    Changes in industry pricing benchmarks could adversely affect the financial performance of the combined company

         Contracts in the prescription drug industry, including Caremark’s and PharmaCare’s contracts with retail pharmacy networks as well as their contracts with clients for PBM and Specialty services, generally use certain published benchmarks to establish pricing for prescription drugs. These benchmarks include average wholesale price, which is referred to as AWP, average selling price, which is referred to as ASP, and wholesale acquisition cost, which is referred to as WAC. Most of Caremark’s and PharmaCare’s PBM client contracts utilize the AWP standard. Further, most of the contracts governing the participation of CVS stores in retail pharmacy networks also utilize the AWP standard.

         Recent events have raised uncertainties as to whether payors, pharmacy providers, PBMs and others in the prescription drug industry will continue to utilize AWP as it has previously been calculated or whether other pricing benchmarks will be adopted for establishing prices within the industry.

         Specifically, in the proposed settlement in the case of New England Carpenters Health Benefits Fund, et al. v. First DataBank, et al., a civil class action case brought against First DataBank, which is referred to as FDB, one of several companies that report data on prescription drug prices, and McKesson Corporation, FDB has agreed to reduce the reported AWP of certain drugs by four percent at a future time as contemplated by the settlement. At this time, the proposed settlement has not received final court approval. The court could approve the proposed settlement in part, in its entirety, or not at all. CVS and Caremark cannot predict the outcome of this case, or, if the settlement is approved, the precise timing of any of the proposed AWP changes or the effect of such changes, if any, on the financial performance of the combined company.

         Over 90% of Caremark’s client relationships and most of its relationships with other affected parties contain terms that Caremark believes will enable it to mitigate any adverse effect of this proposed reduction in FDB’s reported AWP. Two other publicly traded large national PBMs have also stated that their contractual relationships contain similar terms. However, because in some cases payors may seek to negotiate with PBMs in an effort to reduce prescription drug costs as a result of a reduction in FDB’s reported AWP, the ultimate effect of this development on the business of the combined company cannot be precisely predicted.

         Whatever the outcome of the FDB case, it is possible that payors, pharmacy providers and PBMs will begin to evaluate other pricing benchmarks as the basis for contracting for prescription drugs and pharmacy benefit management services in the future.

     

    Existing and new government legislative and regulatory action could adversely affect the combined company’s business and financial results.

         CVS and Caremark are subject to changes in laws and regulations, including changes in accounting standards and taxation requirements and interpretations. As a participant in the healthcare and PBM industries, Caremark’s and CVS’ operations are subject to complex and evolving federal and state laws and regulations and enforcement by

    32






    federal and state governmental agencies. These laws and regulations are described in detail at Part I, Item 1, “Business—Government Regulation” in Caremark’s Annual Report on Form 10-K for the period ended December 31, 2005 and Part I, Item 1A, “Business—Regulatory Risks” in CVS’ Annual Report on Form 10-K for the period ended December 31, 2005.

         Caremark’s and CVS’ pharmacy benefit services businesses and CVS’ retail drugstore business are subject to numerous federal, state and local laws and regulations. Changes in these regulations may require extensive system and operating changes that may be difficult to implement. Untimely compliance or noncompliance with applicable regulations could result in the imposition of civil or criminal penalties that could adversely affect the continued operation of Caremark’s or CVS’ business, including, but not limited to: suspension of payments from government programs; loss of required government certification; approvals; loss of authorizations to participate in or exclusion from government reimbursement programs, such as the Medicare and Medicaid programs; loss of licensure; or significant fines or monetary penalties, and could adversely affect the continued operation of Caremark’s or CVS’ business. The regulations to which Caremark and CVS are subject include, but are not limited to: federal, state and local registration and regulation of pharmacies, pharmacy benefit managers and healthcare insurance companies; applicable Medicare and Medicaid regulations; the Health Insurance Portability and Accountability Act, or HIPAA; accounting standards; tax laws and regulations; laws and regulations relating to the protection of the environment and health and safety matters, including those governing exposure to, and the management and disposal of, hazardous substances; regulations of the U.S. Food and Drug Administration, the U.S. Federal Trade Commission, the Drug Enforcement Administration, and the Consumer Product Safety Commission, as well as state regulatory authorities, governing the sale, advertisement and promotion of products that Caremark or CVS sells; anti-kickback laws; false claims laws; and federal and state laws governing the practice of the profession of pharmacy. Furthermore, the frequency and rate of FDA approval of new brand name and generic prescription drugs or of additional existing prescription drugs for over-the-counter sales could have an impact on CVS’ or Caremark’s business and results of operations.

          The combined company’s business and results of operations could be affected by one or more of the following:

    • federal and state laws and regulations governing the purchase, distribution, management, dispensing and reimbursement of prescription drugs and related services, whether at retail or mail, and applicable licensing requirements;

    • the effect of the expiration of patents covering brand name drugs and the introduction of generic products;

    • approval by the U.S. Food and Drug Administration, which is referred to as the FDA, of over-the-counter status for brand name drugs;

    • FDA regulation affecting the retail or PBM industry;

    • rules and regulations issued pursuant to the Health Insurance Portability and Accountability Act of 1996, which is referred to as HIPAA; and other federal and state laws affecting the use, disclosure and transmission of health information, such as state security breach laws and state laws limiting the use and disclosure of prescriber information;

    • administration of the Medicare Drug Benefit, including legislative changes and/or Centers for Medicare and Medicaid Services rulemaking and interpretation;

    • government regulation of the development, administration, review and updating of formularies and drug lists;

    • state laws and regulations establishing or changing prompt payment requirements for payments to retail pharmacies;

    • impact of network access (any willing provider) legislation on ability to manage pharmacy networks;

    • managed care reform and plan design legislation;

    33






    • insurance licensing and other insurance regulatory requirements applicable to offering a prescription drug plan in connection with the Medicare Drug Benefit; and

    • direct regulation of pharmacies or PBMs by regulatory and quasi-regulatory bodies.
     

    Uncertainty regarding the impact of Medicare Part D may adversely impact the combined company’s business and financial results.

         The Medicare Prescription Drug, Improvement and Modernization Act of 2003, or the MMA, created a new, voluntary prescription drug benefit for Medicare beneficiaries entitled to Medicare benefits under Part A or enrolled in Medicare Part B. The Medicare Drug Benefit became effective on January 1, 2006. Since its inception the program has resulted in increased utilization and decreased pharmacy gross margin rates as higher margin business (such as cash and state Medicaid customers) migrated to the new Medicare Part D coverage. The full impact on the combined company’s sales and gross margin rates cannot yet be determined and could have different effects on different segments of the combined company’s business.

         Caremark and PharmaCare participate in the administration of the Medicare Drug Benefit through the provision of PBM services to their health plan clients and other clients that have qualified as a Medicare Part D prescription drug plan. Caremark also participates (1) through the offering of Medicare Part D pharmacy benefits by its subsidiary, SilverScript Insurance Company, which has been approved by the Centers for Medicare and Medicaid Services, or CMS, as a prescription drug plan sponsor under Medicare Part D in all regions of the country, and (2) by assisting employer, union and other health plan clients that qualify for the retiree drug subsidy available under Medicare Part D by collecting and submitting eligibility and/or drug cost data to CMS for them in order to obtain the subsidy. In addition, PharmaCare, through a joint venture with Universal American Insurance Corp, also participates in the offering of Medicare Part D pharmacy benefits by affiliated entities of Universal American. Caremark’s, PharmaCare’s or after the consummation of the merger, the combined company’s, clients could decide to discontinue providing prescription drug benefits to their Medicare-eligible members. If this occurs, the adverse effects of the Medicare Drug Benefit may outweigh any opportunities for new business generated by the new benefit. Caremark and CVS are not yet able to assess the impact that Medicare Part D will have on clients’ decisions to continue to offer a prescription drug benefit to their Medicare-eligible members. In addition, if the cost and complexity of the Medicare Drug Benefit exceed management’s expectations or prevent effective program implementation or administration; if the government alters or reduces funding of Medicare programs because of the higher-than-anticipated cost to taxpayers of the MMA or for other reasons; if the combined company fails to design and maintain programs that are attractive to Medicare participants; or if the combined company is not successful in retaining enrollees, or winning contract renewals or new contracts under the MMA’s competitive bidding process, Caremark’s and CVS’ Medicare business and the ability to expand the combined company’s Medicare operations could be materially and adversely affected, and the combined company’s business and results of operations may be adversely affected. Finally, the MMA mandated risk corridors (in which the federal government shares in the drug cost risk borne by Part D plans) are scheduled to change in 2008. Both the risk corridor thresholds and the level of risk-sharing will change with the result that Medicare Drug Benefit sponsors will assume an increased level of drug cost risk starting in 2008. Therefore, to the extent that SilverScript Insurance Company’s actual drug costs are higher or lower than those estimated by it in its bid in 2008 onwards, the federal government will share a smaller portion of the losses or gains respectively than it otherwise would have prior to 2008.

     

    Efforts to reduce reimbursement levels and alter health care financing practices could adversely affect the combined company’s businesses.

         The continued efforts of health maintenance organizations, managed care organizations, other pharmacy benefit management companies, government entities, and other third party payors to reduce prescription drug costs and pharmacy reimbursement rates may impact the profitability of the combined company. During the past several years, the U.S. healthcare industry has been subject to an increase in governmental regulation at both the federal and state levels. Efforts to control healthcare costs, including prescription drug costs, are underway at the federal and state government levels. Changing political, economic and regulatory influences may affect health care financing and reimbursement practices. If the current health care financing and reimbursement system changes significantly, the combined company’s business could be materially adversely affected.

    34






         On February 8, 2006, the President signed into law the Deficit Reduction Act of 2005, which is referred to as the DRA. This Act seeks to reduce federal spending by $3.6 billion over a five-year period by altering the Medicaid reimbursement formula for multi-source (i.e., generic) drugs. According to the Congressional Budget Office, retail pharmacies are expected to negotiate with individual states for higher dispensing fees to mitigate the adverse effect of these changes. These changes are expected to take effect during the first quarter of 2007 and to result in reduced Medicaid reimbursement rates for retail pharmacies. The extent of these reductions and the impact on the combined company cannot be determined at this time.

         In addition, Congress periodically considers proposals to reform the U.S. health care system. These proposals may increase government involvement in health care and regulation of PBM or pharmacy services, or otherwise change the way the combined company or its clients do business. Health plan sponsors may react to these proposals and the uncertainty surrounding them by reducing or delaying purchases of cost control mechanisms and related services that the combined company would provide. CVS and Caremark cannot predict what effect, if any, these proposals may have on the combined company’s business. Other legislative or market-driven changes in the health care system that CVS and Caremark cannot anticipate could also materially adversely affect the combined company’s consolidated results of operations, consolidated financial position and/or consolidated cash flow from operations.

     

    CVS and Caremark face litigation risks and are the subject of various legal proceedings.

         CVS and Caremark are subject to litigation risks. The material legal proceedings affecting CVS are described in detail in Part II, Item 1, “Legal Proceedings” of CVS’ quarterly report on Form 10-Q for the period ended September 30, 2006 and Part I, Item 3, “Legal Proceedings” of CVS’ annual report on Form 10-K for the period ended December 31, 2005. The material legal proceedings affecting Caremark are described in detail in Part II, Item 1, “Legal Proceedings”, of Caremark’s quarterly report on Form 10-Q for the period ended September 30, 2006 and Part I, Item 3, “Legal Proceedings” of Caremark’s annual report on Form 10-K for the period ended December 31, 2005. If any of these or new proceedings are determined adversely for Caremark, CVS or the combined company, it could have a material adverse effect on the combined company’s business and results of operations.

         In November 2006, the Iron Workers of Western Pennsylvania Pension Plan filed a purported class action lawsuit purportedly on behalf of Caremark stockholders in the United States District Court for the Middle District of Tennessee against Caremark and its directors. The complaint alleged, among other things, that the directors breached their fiduciary duties by entering into the proposed merger with CVS. The plaintiff sought, among other things, preliminary and permanent injunctive relief to prevent the proposed merger, to direct the defendants to obtain a transaction which is in the best interests of Caremark stockholders, and to impose a constructive trust upon any benefits improperly received by the defendants. In December 2006, the plaintiff moved for a temporary restraining order enjoining certain provisions of the merger agreement, expedited discovery, and an order to show cause why the proposed merger should not be preliminary enjoined. On December 22, 2006, the court denied the plaintiff’s motion for a temporary restraining order. In January 2007, the defendants moved to stay the lawsuit. On January 5, 2007, the court stayed the lawsuit, denied the plaintiff’s motion to expedite discovery and for an order to show cause, and administratively closed the case. The Sheetmetal Workers Local 28 Pension Fund also filed a purported class action lawsuit in the Chancery Court of Davidson County, Tennessee against Caremark and its directors. The complaint alleges, among other things, that the directors breached their fiduciary duties in approving the proposed merger. The plaintiff seeks, among other things, a declaration that the directors breached their fiduciary duties and injunctive relief preventing the proposed merger. In December 2006, the plaintiff sought to transfer the case to the Circuit Court for Davidson County, Tennessee and to consolidate it with the pending In Re: Caremark Rx, Inc. Stock Option Litigation, as described below. The defendants opposed the proposed transfer and consolidation. On January 12, 2007, the Circuit Court denied the proposed transfer and consolidation.

         In December 2006, Laurence M. Silverstein filed a purported class action lawsuit purportedly on behalf of Caremark stockholders relating to the proposed merger between Caremark and CVS in the United States District Court for the Middle District of Tennessee. The suit is brought against Caremark, its directors, CVS, and CVS’ chief executive officer. The complaint alleges, among other things, that the Caremark directors breached their fiduciary duties by entering into the proposed merger with CVS and that the CVS defendants aided and abetted such breaches of duty. The plaintiff seeks, among other things, preliminary and permanent injunctive relief to prevent the proposed

    35






    merger, to direct the defendants to obtain a transaction which is in the best interests of Caremark, and to impose a constructive trust upon any benefits improperly received by the defendants. In January 2007, the plaintiff filed an amended class action complaint and moved for expedited discovery and preliminary injunctive relief. The amended class action complaint adds allegations that the joint proxy statement/prospectus filed on December 19, 2006 omits certain material information. On January 8, 2007, the court stayed the lawsuit and administratively closed the case. On January 10, 2007, the plaintiff moved to vacate the stay order. That motion, which is opposed, is pending.

         The Louisiana Municipal Police Employees’ Retirement System also filed a purported class action lawsuit purportedly on behalf of Caremark stockholders in the Delaware Court of Chancery against Caremark’s directors and CVS. The complaint alleges, among other things, that the directors breached their fiduciary duties by entering into the proposed merger with CVS. The complaint also alleges that the joint proxy statement/prospectus filed on December 19, 2006 omits certain material information. The plaintiff seeks, among other things, preliminary and permanent injunctive relief to prevent the proposed merger. The lawsuit was amended in January 2007 to add the R.W. Grand Lodge of Free & Accepted Masons of Pennsylvania as a plaintiff and to add Caremark Rx, Inc. as a defendant. A hearing on the plaintiffs’ request for preliminary injunctive relief is currently scheduled for February 16, 2007, with the understanding that the plaintiffs may seek an earlier hearing date in the event that the Caremark stockholder meeting is scheduled before February 20, 2007.

         In January 2007, Express Scripts, Inc., which is referred to as Express Scripts, and Skadden, Arps, Slate, Meagher & Flom LLP, which is referred to as Skadden, filed a lawsuit in the Delaware Court of Chancery against Caremark, its directors, CVS, and AdvancePCS. The complaint alleges, among other things, that the directors breached their fiduciary duties by entering into the proposed transaction with CVS. The plaintiffs seek, among other things, declaratory relief and preliminary and permanent injunctive relief to prevent the proposed merger. The plaintiffs also seek declaratory relief holding that Skadden’s representation of Express Scripts does not violate Skadden’s professional, ethical, or contractual obligations. The plaintiffs have moved to have their lawsuit coordinated with the earlier filed lawsuit in the Delaware Court of Chancery as described in the preceding paragraph. That motion is pending.

         In addition to these recently filed lawsuits, a purported second amended shareholder derivative and class action complaint purportedly on behalf of Caremark stockholders was filed in November 2006 by the plaintiffs in the pending In Re: Caremark Rx, Inc. Stock Option Litigation in the Circuit Court for Davidson County, Tennessee. The purported second amended complaint includes purported class action allegations challenging the proposed merger and adds CVS as a defendant. Among other things, the purported second amended complaint alleges that the Caremark directors approved the merger agreement to avoid personal liability in the pending derivative litigation relating to the alleged backdating of stock options. The purported second amended complaint also alleges that CVS aided and abetted the alleged wrongdoing by the directors of Caremark. The plaintiffs seek, among other things, a declaration that the directors breached their fiduciary duties, injunctive relief preventing the defendants from completing the proposed merger, imposition of a constructive trust upon any illegal profits received by the defendants, and punitive damages. In December 2006, the plaintiffs moved for leave to file a third amended shareholder derivative and class action complaint and moved for expedited discovery. In January 2007, the defendants moved to stay the litigation of claims relating to the proposed merger, which the court granted on January 12, 2007. The plaintiffs will be permitted to file an amended complaint addressing only their alleged stock options claims and will not be permitted to seek relief with respect to the proposed merger.

         In November 2006, the plaintiffs in the pending In Re: Caremark Rx, Inc. Derivative Litigation in the United States District Court for the Middle District of Tennessee moved for leave to file a first amended shareholder derivative and class action complaint to add class action allegations challenging the proposed merger. Among other things, the proposed first amended complaint alleges that the Caremark directors approved the merger agreement to avoid personal liability in the pending derivative litigation relating to the alleged backdating of stock options. In the proposed first amended complaint, the plaintiffs seek, among other things, a declaration that the proposed merger is unfair to the plaintiffs, injunctive relief preventing the defendants from completing the proposed merger, and imposition of a constructive trust upon any illegal profits received by the defendants. The plaintiffs’ motion for leave to amend, which is opposed, is pending.

         Caremark believes the claims made in these stockholder lawsuits lack merit and intends to defend them vigorously.

    THE MERGER

         The following discussion contains important information relating to the merger. You are urged to read this discussion together with the merger agreement and related documents attached as annexes to this document before voting on the merger or the amendment to CVS’ charter and issuance of CVS/Caremark common stock.

    Structure of the Merger

         The merger agreement provides for the merger of Caremark with and into Twain MergerSub LLC, a wholly owned subsidiary of CVS that was formed for the purpose of the merger, with Twain MergerSub LLC surviving the merger and remaining a wholly owned subsidiary of CVS. Immediately following the merger, CVS Corporation will be renamed “CVS/Caremark Corporation” and Twain MergerSub LLC will be renamed “Caremark Rx, L.L.C.”.

    Merger Consideration

         At the effective time of the merger, each issued and outstanding share of Caremark common stock will be converted into the right to receive 1.670 shares of CVS/Caremark common stock. Caremark stockholders will receive cash in lieu of any fractional shares of CVS/Caremark common stock that would have otherwise been received in the merger. See “The Merger Agreement—Fractional Shares” beginning on page 107. CVS and Caremark expect that, upon completion of the merger, the Caremark stockholders immediately prior to the merger will own approximately 45.5% of the outstanding common stock of the combined company on a fully diluted basis, and the CVS stockholders immediately prior to the merger will own approximately 54.5% of the outstanding common stock of the combined company on a fully diluted basis. See “The Merger Agreement—Merger Consideration” beginning on page 106.

    Caremark Special Cash Dividend

         On the date of Amendment No. 1 to the merger agreement, CVS separately granted a waiver to Caremark from the restrictions set forth in Section 6.01(b) of the merger agreement to permit Caremark to pay a one-time, special cash dividend to holders of record of Caremark common stock (on a record date to be set by the Caremark board of directors) in the amount of $2.00 per share of Caremark common stock held by each such holder on such record date, which dividend shall, under the terms of the CVS waiver, be declared prior to the Caremark special meeting, but shall only become payable upon or after the effective time of the merger, and such payment shall be conditioned upon occurrence of the effective time of the merger.

    Accelerated Share Repurchase Transaction

         The parties have agreed that as promptly as practicable after the closing of the merger, CVS/Caremark will execute an accelerated share repurchase transaction on customary terms, whereby CVS/Caremark will retire 150 million shares of its common stock (approximately 9.8% of the combined company’s pro-forma outstanding shares after giving effect to the merger). To implement this transaction, CVS/Caremark will enter into an agreement with one or more financial institutions to purchase shares of common stock from each of them and pay each of them for the shares to be retired. The effect of this transaction and the related borrowing by the combined company to finance the transaction will be the immediate reduction of shares outstanding by 150 million shares and an increase in the combined company’s funded debt by approximately $4.8 billion. CVS has received commitments for such financing. It is anticipated that the agreement with the financial institutions will provide for a purchase price adjustment mechanism customary for such a transaction. The purchase price adjustment under such agreement may be subject to limits on the amounts that may be owed by CVS/Caremark or the financial institutions or both.

A thorough discussion took place among the members of the Caremark board of directors concerning the possible transaction, including a discussion of the risks of the transaction, the expected strategic benefits of the transaction, possible regulatory considerations in connection with the transaction, synergies expected to be derived from the business combination, the interests of directors and officers in the merger and financial aspects of the proposed transaction. At the conclusion of the meeting, the Caremark board of directors authorized management to continue negotiations with CVS to seek to resolve the remaining outstanding issues and to continue due diligence with respect to the potential transaction.

         On October 31, 2006, representatives of CVS and representatives of Caremark and each of their respective legal counsel and financial advisors participated in a conference call to resolve the remaining open points in the merger agreement. Between approximately noon on October 31, 2006 and 7:30 a.m., Eastern Time, on November 1, 2006, senior management of CVS and senior management of Caremark and their respective legal and financial advisors finalized the merger agreement and other proposed definitive documentation.

         At approximately 8:30 a.m., Eastern Time, on November 1, 2006, the Caremark board of directors met at JPMorgan’s offices in New York, New York to consider and act upon the proposed business combination between CVS and Caremark. Prior to this meeting, the Caremark board of directors received various materials, including a substantially final draft of the merger agreement. During this meeting, Caremark’s legal counsel reviewed with the Caremark board of directors the legal duties and responsibilities of the Caremark board of directors in connection with the proposed transaction and provided an update on the material terms and provisions of the merger agreement and changes to the merger agreement that had been negotiated since the last meeting of the Caremark board of directors.

         King & Spalding LLP reviewed with the Caremark board of directors the provisions of the draft merger agreement and discussed, among other things, the definition of material adverse effect, the obligations of the parties to obtain clearance for the merger from the Department of Justice and U.S. Federal Trade Commission from an antitrust perspective, the Caremark board of directors’ fiduciary duties under Delaware law, the provisions of the merger agreement relating to the circumstances under which Caremark may engage in discussions and share non-public information with a third party, the Caremark board of directors’ ability to recommend another transaction to the Caremark stockholders, each party’s termination rights and the circumstances under which a break up fee would be payable. King & Spalding LLP also reviewed with the Caremark board of directors revisions made to the merger agreement to address points raised by the Caremark board of directors. In approving the negotiated deal protection provisions contained in the merger agreement, the Caremark board of directors considered, in particular, the following:

    • The fact that the deal protection provisions contained in the merger agreement regarding the circumstances under which the Caremark board of directors could enter into discussions and share non-public information with a third party and change its recommendation permitted the Caremark board of directors to properly exercise its fiduciary duties to Caremark stockholders under Delaware law.

    • The resolution that led to the reduction in the amount of the break up fee and the circumstances under which the break up fee is payable;

    45






    • That revisions were made to the merger agreement in response to the Caremark board of directors’ concerns that Caremark could be responsible for paying the break up fee, but Caremark would not simultaneously be able to enter into a binding agreement with a third party with respect to an acquisition proposal to cover the break up fee, including the revision that, even though Caremark must still submit the merger to the Caremark stockholders for a vote even if the Caremark board of directors no longer supports the merger and changes its recommendation, Caremark is permitted to enter into a binding letter agreement with a third party making a superior proposal, and this letter agreement may (1) provide that the third party is obligated, on behalf of Caremark, to pay any termination fee payable by Caremark in connection with the merger agreement and (2) attach as an exhibit a fully negotiated and executed merger agreement relating to the superior proposal so long as the effectiveness of such agreement and plan of merger is conditioned upon the termination of the merger agreement and the payment of the termination fee by Caremark to CVS in connection with the merger agreement;

    • A survey of the deal protection provisions contained in precedent transactions of similar size and type as the merger;

    • That the deal protection provisions are reciprocal and are customary for strategic business transactions of this type; and

    • That the deal protection provisions are the product of extensive negotiations between the parties.

         Each of the foregoing factors, among others, was considered by the Caremark board of directors in approving the merger agreement.

         Members of Caremark’s senior management then updated the Caremark board of directors on the results of due diligence, the risks associated with the transaction and the strategic benefits of the transaction and related transaction matters. In addition, UBS and JPMorgan reviewed with the Caremark board of directors their joint financial analysis of the exchange ratio and each delivered to the Caremark board of directors an oral opinion, each of which was confirmed by delivery of a written opinion dated November 1, 2006, to the effect that, as of that date and based on and subject to various assumptions, matters considered and limitations described in such opinion, the exchange ratio was fair, from a financial point of view, to holders of Caremark common stock. Following a thorough discussion of the proposed transaction, the Caremark board of directors unanimously voted to approve the merger and the merger agreement and authorized management of Caremark to take certain actions designed to accomplish the transactions contemplated by the merger agreement.

         Following the approval of the merger and the merger agreement, Mr. Ryan was introduced to the Caremark board of directors.

         At approximately 9:00 a.m., Eastern Time, on November 1, 2006, the CVS board of directors met telephonically or in person in New York, New York at the offices of Davis Polk & Wardwell. Before the CVS board of directors convened, directors received a package of materials relating to their review of the proposed transaction. Mr. Ryan opened this meeting by summarizing the then current status of deal negotiations and developments since the board had last met. At the conclusion of Mr. Ryan’s summary, Evercore and Lehman Brothers each gave its own presentation as to the financial analyses performed by it relating to the merger. At the conclusion of each of their respective presentations, each of Evercore and Lehman Brothers rendered their respective opinions orally (each of which opinions was later followed up in writing) to the effect that, as of that date and based on and subject to the assumptions made, procedures followed, matters considered and qualifications and limitations described in each such opinion, the exchange ratio was fair, from a financial point of view, to CVS. After these opinions were rendered, a Davis Polk & Wardwell partner summarized the principal deal terms for the members of the CVS board of directors focusing, in particular, on changes to those terms since the CVS board of directors October 23 meeting including as to the resolution of the deal protection provisions. Thereafter, senior CVS executives reviewed again for the members of the CVS board of directors the strategic rationale for, and benefits expected to be derived from, the transaction. A discussion of the transaction followed this review. At the conclusion of this discussion, the CVS board of directors unanimously approved the merger and the merger

    46






    agreement, resolved to recommend these and related matters to CVS’ stockholders for their approval and authorized CVS management to take certain actions to bring the transaction negotiations to a successful conclusion.

         Following the meetings of the CVS board of directors and the Caremark board of directors, CVS and Caremark executed the merger agreement and thereafter issued a joint press release on November 1, 2006 announcing the transaction.

         On December 18, 2006, Caremark received an unsolicited offer from Express Scripts, Inc., referred to as Express Scripts, pursuant to which Express Scripts offered to acquire all of the outstanding shares of Caremark common stock for $29.25 in cash and 0.426 shares of Express Scripts common stock for each share of Caremark common stock. The receipt of Express Scripts common stock by Caremark stockholders would be tax free, and the cash portion received by Caremark stockholders would be taxable to Caremark stockholders. Express Scripts’ offer was made subject to, among other things, completion of a confirmatory due diligence review of Caremark, termination of the merger agreement with CVS and negotiation and execution of a merger agreement with Express Scripts. The cash portion of the consideration would be financed by Express Scripts and Express Scripts stated that it had commitment letters from Citigroup Corporate and Investment Banking and Credit Suisse to provide the requisite financing to complete the transaction. Caremark did not receive copies of these commitment letters from Express Scripts nor did it receive a conditional merger agreement from Express Scripts.

         On that same day, Caremark issued a press release announcing that the Caremark board of directors would review the terms of the proposal submitted by Express Scripts in a manner consistent with its obligations under the merger agreement with CVS and applicable Delaware law. CVS also issued a press release reaffirming its support of the merger with Caremark and its confidence in the long-term strategic value of the combination as well as the benefit to the stockholders of both Caremark and CVS.

         Also on that day, the Caremark board of directors met telephonically to discuss Express Scripts’ proposal. King & Spalding LLP, legal counsel to Caremark, gave a presentation to the Caremark board of directors regarding the directors’ fiduciary duties under Delaware law and reviewed with the Caremark board of directors the requirements of the merger agreement with CVS in connection with receipt and analysis of Express Scripts’ proposal. Caremark’s financial advisors also participated in the meeting.

         On December 20, 2006, the initial waiting period for the merger with CVS required by the HSR Act expired without a Request for Additional Information (commonly referred to as a “second request”) from the U.S. Federal Trade Commission.

         On December 22, 2006, the Caremark board of directors met in Nashville, Tennessee to discuss Express Scripts’ proposal. During this meeting, King & Spalding LLP and Wachtell, Lipton, Rosen & Katz, special counsel, reviewed with the Caremark board of directors the legal standards under Delaware law and related legal considerations applicable to the Caremark board of directors’ review of Express Scripts’ proposal, including a thorough analysis of the applicable requirements of the merger agreement with CVS. Jones Day, Caremark’s antitrust counsel, reviewed possible antitrust implications of the Express Scripts proposal with the Caremark board of directors. Caremark’s financial advisors reviewed with the Caremark board of directors financial aspects of Express Scripts’ proposal as compared to those of the merger with CVS. Management of Caremark gave a presentation to the Caremark board of directors regarding strategic and business considerations of a possible business combination with Express Scripts as compared to the merger with CVS. The Caremark board of directors then met in an executive session.

         On December 22, 2006, the CVS board of directors met telephonically. At the commencement of the meeting, Mr. Ryan provided a general update to the CVS board of directors regarding developments with respect to Express Scripts. Davis Polk & Wardwell thereafter summarized Express Scripts’ proposal. Following that summary, representatives of CVS’ financial advisors, Evercore and Lehman Brothers, discussed Express Scripts’ proposal from a financial and market perspective. Davis Polk & Wardwell then summarized potential next steps. Thereafter, the CVS board of directors met in executive session.

    47






         On December 23, 2006, Mr. Crawford telephoned Mr. Ryan to discuss CVS’ possible response to Express Scripts’ proposal. Mr. Ryan stated that CVS will have an upcoming board meeting and indicated to Mr. Crawford that CVS remains fully committed to the pending merger with Caremark and will move forward promptly to present the pending merger to the respective stockholders of Caremark and CVS for their respective approvals as contemplated under the merger agreement with CVS.

         On December 27, 2006, the Caremark board of directors met telephonically to discuss Express Scripts’ proposal further. King & Spalding LLP also participated in the meeting. The Caremark board of directors determined to reconvene on January 5, 2007 for further review and discussion of the proposal.

         On January 2, 2007, Caremark retained Banc of America Securities LLC to act as an additional financial advisor to Caremark.

         On January 3, 2007, the Caremark board of directors met telephonically and was updated on events concerning the Express Scripts proposal.

         On January 5, 2007, Morgan Stanley & Co. Incorporated was retained to act as a financial advisor to CVS in connection with the merger.

         On January 5, 2007, the Caremark board of directors met in Nashville, Tennessee to further review the Express Scripts proposal. During this meeting King & Spalding LLP and Wachtell, Lipton, Rosen & Katz reviewed with the Caremark board of directors the legal standards under Delaware law and related legal considerations applicable to the Caremark board of directors' review of Express Scripts' proposal, including a thorough analysis of the applicable requirements of the merger agreement with CVS. Jones Day, Caremark's antitrust counsel, reviewed possible antitrust implications of the Express Scripts proposal with the Caremark board of directors. UBS and JPMorgan reviewed with the Caremark board of directors financial aspects of Express Scripts' proposal as compared to those of the merger with CVS including, among other things, an overview of the Express Scripts proposal and an overview of the CVS transaction, the impact of the relative synergies attributable to each transaction and implied transaction values of the Express Scripts proposal and the CVS transaction. Management of Caremark gave a presentation to the Caremark board of directors regarding strategic and business considerations of a possible business combination with Express Scripts as compared to the merger with CVS. After thoroughly reviewing the Express Scripts proposal as set forth in its December 18th letter and after consulting with its outside legal and financial advisors and upon consideration of a variety of factors, the Caremark board of directors unanimously determined that the Express Scripts proposal does not constitute, and is not reasonably likely to lead to, a “Superior Proposal” as defined in the merger agreement with CVS. As a result, the Caremark board of directors unanimously concluded that, consistent with its fiduciary duties under Delaware law, the Express Scripts proposal does not meet the requisite standards established under the merger agreement for permitting Caremark to engage in discussions with Express Scripts and that engaging in discussions with Express Scripts is not in the best interests of Caremark and its stockholders. The Caremark board of directors has therefore determined not to enter into discussions with Express Scripts or to provide Express Scripts with access to confidential information concerning Caremark consistent with the board of directors’ obligations under the merger agreement with CVS.

         The Caremark board of directors considered a number of factors in connection with its evaluation of Express Scripts’ proposal, as described in more detail below. In view of the number of factors and complexity of these matters, the Caremark board of directors did not find it practicable to, nor did it attempt to, quantify, rank or otherwise assign relative weight to the specific factors it considered.

         Lacks Strategic Rationale. There is no logical or compelling strategic rationale for a combination of Express Scripts and Caremark. Simply creating a larger pharmacy benefits manager does not address evolving market dynamics, including an increasingly consumer-centric healthcare environment, and greater demand for access to information, personalized pharmaceutical and disease management services, and the ability to better manage costs.

         In contrast to the merger with CVS, Express Scripts’ proposal would not provide Caremark with any unique services, programs or tools that could serve to address emerging healthcare trends, improve clinical outcomes, or help consumers manage costs and improve their health.

    48






         Creates the Risk of Significant Customer Attrition and Destruction of Stockholder Value. Express Scripts’ proposal creates substantial business risks and potential near- and long-term destruction of stockholder value resulting from the likely loss of existing and prospective customers. Given that the Caremark stockholders would own 57% of the combined company under the Express Scripts’ proposal, they would bear the majority of these adverse consequences. Customers, including some of Caremark’s largest customers, have voiced strong opposition towards an Express Scripts/Caremark combination. These unsolicited comments to Caremark are in stark contrast to the extremely favorable response customers have had to the CVS/Caremark merger.

         Caremark believes that uncertainties created by pursuing Express Scripts’ proposal would disrupt and adversely impact at a minimum the 2007 selling season, which extends through the first three quarters of the year. Caremark also believes that the uncertainties presented by the Express Scripts’ proposal would virtually eliminate new business opportunities and make it difficult to renew existing contracts.

         Express Scripts’ recently reported financial results have raised questions about its ability to effectively integrate recent acquisitions. Additionally, all of Express Scripts’ past acquisitions have been significantly smaller than those completed by Caremark and CVS, and Express Scripts has no experience integrating a business the size of Caremark. In contrast, Caremark and CVS have an established track record of successfully integrating large-scale acquisitions, and these strong management teams are committed to remaining in place to integrate and manage the combined company.

         Intended to Derail the Strategic and Compelling CVS/Caremark Merger and Is a Defensive Move by Express Scripts. Unlike Caremark’s and CVS’ decision to enter into a merger from positions of strength and provide plan sponsors and consumers with the products and services they desire, Express Scripts’ proposal is reactionary and defensive. Caremark believes that Express Scripts’ interference with the CVS/Caremark merger reflects Express Scripts’ concerns about the enhanced competition due to the innovative services created by a CVS/Caremark combination and the change in industry landscape that would result. Several of Caremark’s clients have notified Caremark that Express Scripts has contacted them in an effort to disrupt Caremark’s relationship with the client. Also, Express Scripts has lost approximately $1 billion in net business to Caremark over the last three years. Clearly, Express Scripts fears a greater loss in business when facing an even stronger combined CVS/Caremark.

         Questionable Assumptions Regarding the Calculation of Synergies. Caremark has substantial doubts regarding the reliability of the synergy estimates espoused by Express Scripts, based on Caremark’s own knowledge and experience in developing synergy estimates. Express Scripts’ synergy analysis also fails to address the substantial potential negative synergies which could arise from a combination of Express Scripts and Caremark. In addition to the potential loss of business, factors such as the two companies’ vastly different formularies, contracting practices, and adjudication engines and systems create both integration risk and potential for additional negative synergies.

         Faces Significant, if Not Insurmountable, Antitrust Risks and Timing Delays. Express Scripts’ proposal carries significant antitrust risk that could substantially delay closing, could prevent closing altogether, or could result in the imposition of conditions that could adversely impact the business, projected synergies, Express Scripts’ ability to obtain financing for such a transaction, and the terms of such financing. Potential remedies that could be sought by antitrust regulators would be difficult to execute in the pharmacy benefits management business given its service orientation and could negatively affect any potential benefits projected by Express Scripts.

         Caremark’s merger with CVS has received antitrust clearance without a second request and is expected to close in the first quarter of 2007, while Express Scripts has just begun the antitrust approval process and Express Scripts does not expect to close its proposed transaction until the third quarter of 2007 at the earliest.

         Highly Leveraged and Weakened Business with Diminished Financial Strength and Flexibility. Express Scripts’ proposal would create one of the most leveraged public companies in the healthcare services industry. With Express Scripts’ free cash flow dedicated to debt reduction for several years, the combined company would be severely restricted in its ability to invest in its business, pursue other strategic opportunities, react to changing market dynamics, or engage in value creating financial transactions beneficial to stockholders such as share repurchases and dividends. The concern over leverage associated with Express Scripts’ proposal is further evidenced by S&P’s recent decision to place Express Scripts on negative watch, a measure that is in contrast to the

    49






    positive watch that CVS received following the merger announcement with Caremark. Negative synergies associated with lost customer accounts or antitrust remedies would only further increase these risks and concerns.

         A combined CVS/Caremark will have significant free cash flow, an investment grade credit rating, and considerable borrowing power, giving it substantial financial flexibility to invest in its business and pursue opportunities to enhance stockholder value, including through a continuation of dividend payments and potential future share buybacks.

         Other Factors. The Caremark board of directors also considered certain other factors relating to the merger agreement with CVS and the Express Scripts proposal including:

         Express Scripts did not disclose its financing and any conditions to the financing that may exist, such as a material adverse effect condition.

         Express Scripts has expressly conditioned its willingness to enter into any binding agreement with Caremark on the prior termination of the merger agreement with CVS, as opposed to offering to execute a conditional merger agreement, as permitted by Section 8.07(g) of the merger agreement with CVS. Because there is no conditional merger agreement, which is typical in competing merger proposals, Express Scripts has failed to offer to advance the break-up fee that could become payable to CVS. Accordingly, the risk of the break-up fee under the CVS merger agreement ($675 million) would be borne by Caremark without any guarantee that Express Scripts would even carry on with its proposal, much less any guarantee that the transaction would be approved by regulators and stockholders. Thus, the Caremark board cannot envision any scenario where it would be willing to trigger the imposition of a $675 million break up fee without having a competing party obligated to fund that payment.

         On January 5, 2007, following the Caremark board of directors’ meeting, Mr. Crawford called Mr. Ryan to advise him of the Caremark board of directors’ determination.

         On January 7, 2007, Caremark issued a press release announcing that the Caremark board of directors, after thorough consideration and consultation with its legal and financial advisors, has determined that the Express Scripts proposal does not constitute, and is not reasonably likely to lead to, a superior proposal under the terms of the merger agreement. Caremark further announced that the Caremark board of directors unanimously has concluded that pursuing discussions with Express Scripts is not in the best financial or strategic interests of Caremark and its stockholders.

         On January 8, 2007, Express Scripts gave notice to Caremark that Kew Corp, a wholly owned subsidiary of Express Scripts, has purchased shares of Caremark common stock and, as a stockholder of Caremark, intends to nominate four candidates for election to the Caremark board of directors at Caremark's 2007 annual meeting of stockholders, if it is held.

         On January 10, 2007, Express Scripts filed a preliminary proxy statement with the SEC for the solicitation of proxies in opposition to the merger between CVS and Caremark.

         On January 10, 2007, at a regularly scheduled meeting of the CVS board of directors, CVS' management and its financial and legal advisors updated the CVS board of directors on the transaction generally as well as on recent developments with respect to Express Scripts.

          On January 13, 2007, Mr. Ryan called Mr. Crawford and proposed that Caremark effect a special cash dividend in an amount equal to $2.00 per outstanding share of Caremark common stock and that such special cash dividend be declared by Caremark prior to the effective time of the merger and be paid at or immediately following the effective time of the merger. Payment of this special cash dividend would be conditioned on the completion of the merger. Mr. Ryan also proposed that the parties agree that, after the completion of the merger, the combined company will effect an accelerated share repurchase transaction whereby CVS/Caremark will retire approximately 150 million shares of common stock of the combined company. Mr. Ryan’s proposal is referred to collectively as the CVS proposal.

          On January 13, 2007, CVS’ and Caremark’s respective tax counsel discussed the CVS proposal and determined that, in order to implement the CVS proposal in a tax efficient manner, the parties should consider changing the structure of the merger from a reverse triangular merger to a forward triangular merger. Therefore, if the merger structure were changed, Caremark would be merged with and into a limited liability company wholly owned by CVS, with the limited liability company surviving the merger as a wholly owned subsidiary of CVS. On this same day, CVS’ legal counsel distributed an initial draft of an amendment to the merger agreement to reflect a forward merger structure and an initial draft of a letter agreement to reflect the parties’ agreement with respect to the special cash dividend and the accelerated share repurchase transaction. The terms of these documents were negotiated on January 14 and 15.

          On January 15, 2007, the Caremark board of directors met telephonically to discuss the CVS proposal and Caremark’s management and legal counsel reviewed with the Caremark board of directors the CVS proposal. UBS and JPMorgan reviewed with the Caremark board of directors the financial aspects of the Caremark/CVS merger as amended by the CVS proposal as compared to those of the proposal submitted by Express Scripts on December 18, 2006. UBS and JPMorgan each separately informed the Caremark board of directors that its view as to the fairness from a financial point of view and as of the date of its opinion of the exchange ratio provided for in the CVS transaction had not changed. Caremark’s management and legal counsel then discussed with the Caremark board of directors that, for tax purposes, to implement the CVS proposal in a tax efficient manner the structure of the merger should be changed from a reverse triangular merger to a forward triangular merger, which would mean that Caremark would merge with and into a wholly owned subsidiary of CVS, with the CVS subsidiary surviving the merger. Caremark’s legal counsel also reviewed with the Caremark board of directors a draft amendment to the merger agreement to effect the change in merger structure and a draft letter agreement which would reflect Caremark’s and CVS’ agreement with respect to the special cash dividend and the accelerated share repurchase transaction. The Caremark board of directors thoroughly discussed the CVS proposal, including the special cash dividend, the accelerated share repurchase transaction and the resulting change in the merger structure. The Caremark board of directors unanimously determined that the CVS proposal is advisable and in the best interests of Caremark and the Caremark stockholders and authorized Caremark’s management to proceed with the CVS proposal. The Caremark board of directors also stated its intention to declare the special cash dividend on a date to be determined by the Caremark board of directors prior to the completion of the merger and that such special cash dividend will be conditioned on the completion of the merger and will be paid at or immediately following the effective time of the merger. The Caremark board of directors also acknowledged that its compensation committee will need to make adjustments prior to the effective time of the merger to Caremark’s outstanding stock options to reflect the special cash dividend. The actions taken by the Caremark board of directors at this meeting were subject in all respects to the approval of the CVS proposal in its entirety at the CVS board meeting scheduled for January 16, 2007.

          On January 16, 2007, Express Scripts announced that it is commencing an exchange offer for all of the outstanding shares of Caremark common stock. The offer is based on the same cash and stock proposal set forth in Express Scripts’ letter, dated December 18, 2006. In accordance with applicable law, on or before January 30, 2007, Caremark intends to provide its stockholders a statement of its position with respect to the exchange offer.

         On January 16, 2007, the CVS board of directors met telephonically. Mr. Ryan opened this meeting by summarizing developments since the board had last met and gave an overview of two proposed enhancements to the merger transaction, namely a proposed special cash dividend by Caremark to its stockholders conditioned on completion of the merger and a proposed accelerated share repurchase transaction to be effected by the combined company promptly after the merger. Morgan Stanley then gave a presentation covering the terms and structure of the special cash dividend and the accelerated share repurchase transaction. Thereafter, Evercore and Lehman Brothers each gave its own presentation as to the financial analyses performed by it relating to the merger, taking

    50






    into account the Caremark special cash dividend and the accelerated share repurchase transaction. At the conclusion of each of their respective presentations, each of Evercore and Lehman Brothers delivered to the CVS board of directors separate oral opinions, which opinions were confirmed by delivery of separate written opinions dated January 16, 2007, to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken described in each such opinion, the exchange ratio provided for in the merger was fair, from a financial point of view, to CVS. After these opinions were rendered, Mr. Rickard, Mr. Sgarro and a Davis Polk & Wardwell partner answered questions from CVS board members regarding the transaction. A discussion of these matters then ensued. At the conclusion of this discussion, the CVS board of directors unanimously approved Amendment No. 1 to the merger agreement and a waiver agreement with respect to the Merger Agreement relating to the Caremark special cash dividend and the accelerated share repurchase transaction.

    Rationale for the Merger

         CVS and Caremark each have a long history of being managed with a goal of enhancing stockholder value. While CVS and Caremark both believe that they have strong growth prospects for the near- and long-term as stand-alone entities, both companies believe that a combination of their companies represents the next logical and timely step in the evolution of the pharmacy services industry. The merger is expected to yield significant benefits for employer and health plan customers through more effective cost-management solutions and innovative programs and for consumers through expanded choice, unparalleled access and more personalized services. It is also expected to drive substantial value for stockholders of both companies by achieving significant anticipated benefits to be derived from the merger and the creation of a compelling platform from which to accelerate growth.

         CVS and Caremark anticipate that the combined company will be positioned to deliver these benefits and enhance stockholder value as a result of the following:

    • Strategic Benefits;

    • Enhanced Customer Service/Improved Outcomes and Cost Controls;

    • Operating Synergies;

    • Financial Benefits; and

    • Compatible Cultures and Record of Successful Transactions.

         Strategic Benefits. There are a number of reasons that CVS and Caremark believe the merger represents the logical evolution of the pharmacy services industry, including the fact that it combines Caremark’s expertise in serving employers and health plans as a leading pharmacy benefit manager and mail order pharmacy with CVS’ expertise in serving consumers as the nation’s largest retail pharmacy chain based on store count.

         Caremark, one of the nation’s leading pharmaceutical services companies, provides comprehensive prescription benefit management services to over 2,000 health plans, including corporations, managed care organizations, insurance companies, unions and government entities. Caremark is also a sponsor of SilverScript prescription drug plans, one of the top ten prescription drug plans (based on enrolled members) offered to Medicare Part D beneficiaries. Caremark operates a national retail pharmacy network with over 60,000 participating pharmacies and owns and operates seven mail order pharmacies and nine call centers. Through its Accordant disease management offering, Caremark also provides disease management programs for 27 conditions. Twenty-one of these programs are accredited by the National Committee for Quality Assurance.

         CVS operates the nation’s largest retail pharmacy chain based on store count, with approximately 6,200 stores across 43 states and the District of Columbia as well as PharmaCare, a wholly owned pharmacy benefit management and specialty pharmacy subsidiary which is expected to generate approximately $3 billion in revenues during its 2006 fiscal year. PharmaCare operates four mail order facilities and more than 50 specialty retail pharmacies. Through a joint venture arrangement with Universal American Financial Corp., PharmaCare retains an equity interest in Prescription Pathways, one of the top ten Medicare Part D prescription drug plans in the country (based

    51





    on members enrolled). CVS also provides healthcare services through its MinuteClinic subsidiary, which as of September 30, 2006 operates over 99 healthcare clinics, 82 of which are located in CVS stores. MinuteClinic was the first and as of the date hereof remains the only retail-based clinic company to receive accreditation from JCAHO.

         Based on September 30, 2006 data, the combined company will be:

    • #1 in retail pharmacy sales;

    • #1 in PBM lives managed;

    • #1 in pharmacy claims processed;

    • #1 in specialty pharmacy sales;

    • #2 in mail order pharmacy sales; and

    • #1 in retail-based clinics.

         Consequently, the combined company will offer to employers, health plans and consumers fully integrated end to end pharmacy services, from pharmacy plan design analysis to claims processing to retail or mail order prescription fulfillment. The merger will also enable the combined company to offer employers and health plan customers and consumers new and innovative programs, greater choice, unparalleled access and more personalized services. In that regard, the combined company will employ more than 180,000 people, including more than approximately 21,000 pharmacists and nurse practitioners.

         In addition, the merger will combine PharmaCare’s specialty operations with Caremark’s specialty operations thereby creating a premier specialty pharmacy provider, with more than 70 specialty retail and mail pharmacies. Specialty pharmacy focuses on supporting individuals that require complex and expensive drug therapies to treat chronic or genetic-based conditions such as organ transplants, HIV/AIDS, rheumatoid arthritis, hepatitis C, hemophilia, infertility, multiple sclerosis and certain cancers. As a result of the merger, the combined company will put together CVS’ and Caremark’s complementary specialty pharmacy offerings to achieve a more comprehensive specialty pharmacy business in terms of diseases covered and will offer expanded distribution capability and patient access through its retail and mail services pharmacies. CVS and Caremark both believe that the combined company will afford employers, health care plans and consumers with significantly enhanced specialty pharmacy services and capabilities by combining the companies’ complementary specialty businesses, providing them with better alternatives and the combined company with greater opportunities to improve its business than would be available to either company individually.

         Enhanced Customer Service/Improved Outcomes and Cost Controls. CVS and Caremark believe the merger addresses the rapidly changing dynamics of today’s healthcare delivery system. Healthcare is becoming more consumer-centric as the U.S. healthcare system strains to manage growing costs and employers shift more responsibility for managing costs to employees. An aging population, increasing incidence of chronic disease and increasing utilization attributable to the Medicare prescription benefit is fueling demand for prescriptions and pharmacy services. Generic drugs are becoming more widely available and new drug therapies to treat unmet healthcare needs and reduce hospital stays are being introduced. Consumers require medication management programs and better information to help them navigate these trends. CVS and Caremark believe the merger will position the combined company to provide solutions that address these trends and result in an enhanced pharmacy services experience for consumers.

         The combined company will seek to drive value for pharmacy services customers through an enhanced ability to assist and provide actionable information to plan participants and more effectively manage pharmacy cost trends. CVS and Caremark expect the combined company to improve clinical outcomes by providing an integrated information network, improving formulary compliance and appropriate utilization of drug therapy. The combined company intends to utilize CVS’ retail presence and over approximately 21,000 pharmacists and nurse practitioners and Caremark’s systems and clinical programs and services to accomplish this goal. CVS and Caremark believe this

    52





    will result in better control over healthcare costs for employers and health plans. The combined company will also be better positioned to offer new and broader disease management and wellness services to help consumers manage and protect against potential health risks and mitigate future healthcare costs.

         Cost Savings. CVS and Caremark believe the combined company can be operated more efficiently than either company on its own. First, the combined company is now expected to achieve in excess of $500 million in pre-tax benefits from purchasing scale and operating synergies. Operating synergies refers to decreases in overhead expense, increases in productivity and efficiencies, decreases in prescription dispensing costs, and other benefits made possible by combining complementary operations. The estimated $400 million in synergies was updated to in excess of $500 million as a result of the additional integration work completed since receiving antitrust clearance on December 20, 2006.

    • Significant cost savings are expected to come from lower costs for purchased items (such as generic pharmaceuticals) that CVS and Caremark believe will be possible because of the combined company’s buying efficiencies.

    • A portion of cost savings is also expected to come from reduced selling and administrative expenses. These reduced expenses would include eliminating duplicative facilities and/or activities in the two companies, resulting in lower support costs such as occupancy expense, telephone, travel and computer costs. CVS and Caremark also anticipate that the combined company will be able to reduce fees for duplicate activities, such as auditing, SEC reporting and other public company costs.

         Information regarding the uncertainties associated with realizing these anticipated cost savings is described under the heading “Risk Factors—The combined company may be unable to successfully integrate CVS’ and Caremark’s operations or to realize the anticipated cost savings and other benefits of the merger. As a result, the value of CVS/Caremark common stock may be adversely affected.” beginning on page 28 and “Risk Factors—The combined company will incur significant transaction and merger-related costs in connection with the merger.” beginning on page 30.

         Financial. Combined pro forma revenues for CVS and Caremark would have been approximately $72 billion based on the year ended December 31, 2005. Thus, CVS and Caremark believe the combined company will have the size and financial stability to capitalize on anticipated growth opportunities. The merger is expected to further strengthen the mix of revenue sources, providing improved financial flexibility and strong cash-flows.

         Compatible Cultures and Record of Successful Transactions. CVS and Caremark share a number of important long-term corporate values, including a commitment to enhancing stockholder value, an emphasis on efficiency, investment discipline and asset productivity, a focus on customer service and satisfaction, and a commitment to compliance, safety and health. Both companies also benefit from talented and dedicated employees with a track record of successfully integrating companies in various business combination transactions that CVS and Caremark each believe have enhanced stockholder value for each company. CVS and Caremark believe that the shared values and experience of our management teams will facilitate an integration of the two companies, and that this business combination will provide further opportunities to enhance stockholder value.

    CVS Reasons for the Merger

         In approving the transaction and making these recommendations, the CVS board of directors consulted with CVS’ management, as well as its outside legal counsel and CVS’ financial advisors, and it carefully considered the following factors:

    • all the reasons described above under “—Rationale for the Merger” beginning on page 51 including the strategic benefits, the near- and longer-term synergies and purchasing scale and growth opportunities expected to be available to the combined company;

    • information concerning the business, assets, capital structure, financial performance and condition and prospects of CVS and Caremark, focusing in particular on the quality of Caremark’s assets, the compatibility of the two companies’ operations and opportunities for revenue growth;

    53





    • current and historical prices and trading information with respect to each of Caremark’s and CVS’ common stock, which assisted the CVS board of directors in its conclusion that the merger was fairly priced;

    • the possibility, as alternatives to the merger, of pursuing an acquisition of or a business combination or joint venture with an entity other than Caremark or a joint venture with Caremark, and the CVS board of directors’ conclusion that a merger with Caremark is more feasible, and is expected to yield greater benefits, than the likely alternatives. The CVS board of directors reached this conclusion for reasons including Caremark’s interest in pursuing a transaction with CVS, CVS’ view that the transaction could be acceptably completed from a timing and regulatory standpoint, and CVS management’s assessment of the alternatives and the expected benefits of the merger and compatibility of the companies, as described under “Rationale for the Merger” beginning on page 51;

    • the value of the exchange ratio provided for in the merger agreement relative to the then-current market prices and historical trading prices of CVS and Caremark common stock over the past one year period and relative to the consideration paid in business combinations of comparable size, as discussed in our financial advisors’ comparable transaction analysis;

    • current industry, economic and market conditions, including the dynamic pace of change in the U.S. healthcare industry, the increasing trend towards consumer demands for access, convenience and flexibility, and the growing convergence of employer and retail customer interests in mitigating healthcare cost, improving outcomes and benefits and plan design;

    • the likelihood of the enhancement of the strategic position of the combined company, which combines CVS’ and Caremark’s complementary businesses, and creates a broader company with enhanced operational and financial flexibility and increased opportunity for growth;

    • the terms and conditions of the merger agreement, which include restrictions on the conduct of CVS’ and Caremark’s respective businesses pending closing but which permit each of CVS and Caremark generally to conduct its business in the ordinary course during that period (see “The Merger Agreement” beginning on 106);

    • the potential effect of the terms of the merger agreement with respect to possible third party proposals to acquire CVS after execution of the merger agreement, including that if any third party made a superior proposal (as described under “The Merger Agreement—Termination” beginning on page 115), the CVS board of directors could provide information to and engage in negotiations with such third party, subject to the terms and conditions of the merger agreement;

    • that while the termination payment provisions of the merger agreement could have the effect of discouraging alternative proposals for a business combination with CVS, these provisions would not preclude bona fide alternative proposals, and that the size of the termination fee was reasonable in light of the size and benefits of the transaction and not preclusive of a superior transaction, if one were to emerge;

    • the fact that CVS stockholders would hold approximately 54.5% of the outstanding shares of the combined company after the merger;

    • the analyses and presentations prepared by each of Evercore and Lehman Brothers and their respective opinions, dated as of November 1, 2006 and January 16, 2007, that, as of those dates based upon the assumptions made, procedures followed, matters considered and qualifications and limitations on the review set forth in their respective opinions, as of those dates the exchange ratio provided for in the merger was fair from a financial point of view to CVS. Each of Evercore’s and Lehman Brothers’ opinions dated January 16, 2007 is described in detail below under the heading “—Opinions of Financial Advisors to the CVS Board of Directors” beginning on page 56;

    • the challenges of combining the businesses of two corporations of this size and the attendant risks of not achieving the expected strategic benefits, cost savings, other financial and operating benefits or

    54





      improvement in earnings, and of diverting management focus and resources from other strategicopportunities and from operational matters for an extended period of time;

    • that, while the merger is likely to be completed, there are risks associated with obtaining necessary approvals on terms that satisfy closing conditions to the respective parties’ obligations to complete the merger, and, as a result of certain conditions to the completion of the merger, it is possible that the merger may not be completed even if approved by stockholders (see “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114);

    • that, upon completion of the merger, Thomas M. Ryan, the current chairman, president and chief executive officer of CVS, will become the chief executive officer of the combined company and is expected to remain in that position until at least January 2010, and David B. Rickard, current chief financial officer and chief administrative officer of CVS, will be the chief financial officer of the combined company, and that, upon completion of the merger, E. Mac Crawford, the current chairman, president and chief executive officer of Caremark, will become the chairman of the board of directors of the combined company, and Howard A. McLure, Caremark’s current senior executive vice president and chief operating officer, will run the combined company’s pharmacy services business;

    • regulatory and litigation risks associated with the transaction or combining the two companies; and

    • the ability to complete the merger as a tax-free reorganization for U.S. federal income tax purposes.

         In view of the number and wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the CVS board of directors did not find it practicable to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered. In addition, the CVS board of directors did not undertake to make any specific determination as to whether any particular factor was favorable or unfavorable to the CVS board of directors’ ultimate determination or assign any particular weight to any factor, but conducted an overall analysis of the factors described above, including through discussions with and questioning of CVS’ management and management’s analysis of the proposed merger based on information received from CVS’ legal, financial and accounting advisors. In considering the factors described above, individual members of the CVS board of directors may have given different weight to different factors.

         In considering the recommendation of the CVS board of directors with respect to the proposals to amend the CVS charter and issue shares of CVS/Caremark common stock in the merger, you should be aware that certain CVS directors and officers have arrangements that cause them to have interests in the transaction that are different from, or are in addition to, the interests of CVS stockholders generally. See “Interests of CVS Executive Officers and Directors in the Merger” beginning on page 74.

         The CVS board of directors considered all these factors together and, on the whole, thought them to be favorable to, and to support, its determination to recommend approval by CVS stockholders of the proposals necessary to complete the merger.

    Recommendations of the CVS Board of Directors

         At its November 1, 2006 meeting, after due consideration with CVS management and CVS’ legal and financial advisors, the CVS board of directors unanimously determined that the merger agreement, and the transactions contemplated therein, including the issuance of CVS/Caremark common stock in the merger and the amendments to the CVS charter, are advisable and in the best interests of CVS and the CVS stockholders. Accordingly, the CVS board of directors unanimously recommends to its stockholders that they vote “FOR” the proposal to amend the CVS charter to increase the number of authorized shares of CVS common stock and change the name of CVS Corporation to CVS/Caremark Corporation, “FOR” the proposal to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger and “FOR” the adjournment or postponement of the CVS special meeting, including if necessary, to solicit additional proxies in favor of the amendments and issuance.

    55





    CVS Projections

         In connection with the review of the merger, certain financial projections prepared by management of CVS concerning CVS on a stand-alone, pre-merger basis, were exchanged with Caremark.

         The projections are “forward-looking statements” and CVS’ actual results may differ materially from those set forth in the projections. See “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 38 for a discussion of the risks you should consider in reviewing the projections set forth in this joint proxy statement/ prospectus.

         The material portions of the financial projections prepared by management of CVS can be summarized as follows:

    CVS

        2006E   2007E
       
     
                 
    Net Revenue (in millions)   $ 43,852   $ 49,621
    Earnings Per Share   $ 1.54   $ 1.89

         These projections were not prepared with a view to public disclosure or compliance with published guidelines established by the SEC or the American Institute of Certified Public Accountants regarding projections. None of CVS, Caremark or their respective affiliates or CVS’ or Caremark’s independent registered public accounting firm assumes any responsibility if future results differ from these projections. The projections are subjective in many respects and thus susceptible to interpretation and periodic revision based on actual experience and recent developments. While presented with numeric specificity, the projections reflect numerous assumptions made by the management of CVS with respect to industry performance and competition, general business, economic, market and financial conditions and other matters, all of which are difficult to predict and many of which are beyond the control of CVS. For these reasons, the inclusion of the projections in this document should not be regarded as an indication that CVS, Caremark, any recipient of the projections or their respective affiliates or representatives considered or consider the projections to be necessarily predictive of actual future events, and the projections should not be relied upon as such. Actual results may be higher or lower than those estimated. CVS and Caremark do not generally publish their respective business plans and strategies or make external disclosures of their respective anticipated financial position or results of operations. Accordingly, CVS and Caremark do not intend to, and specifically decline any obligation to, update or otherwise revise the prospective financial information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even if any or all the underlying assumptions are shown to be in error. Also, CVS and Caremark do not intend to, and specifically decline any obligation to, update or revise the prospective financial information to reflect changes in general economic or industry conditions. Neither CVS’ auditors nor Caremark’s auditors, nor any other independent registered public accounting firm, have compiled, examined or performed any procedures with respect to these projections, nor have they expressed any opinion or any other form of assurance on this information or its achievability, and assume no responsibility for, and disclaim any association with, this prospective financial information.

    Opinions of Financial Advisors to the CVS Board of Directors

         CVS retained Evercore and Lehman Brothers as financial advisors to the CVS board of directors in connection with the merger.

         On November 1, 2006, at a meeting of the CVS board of directors held to evaluate the proposed merger, Evercore and Lehman Brothers delivered to the CVS board of directors separate oral opinions, which opinions were confirmed by delivery of separate written opinions dated November 1, 2006, to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken described in each such opinion, the exchange ratio provided for in the merger was fair, from a financial point of view, to CVS.

         On January 16, 2007, at a meeting of the CVS board of directors held to evaluate the proposed amendment to the merger agreement and the proposed waiver agreement, Evercore and Lehman Brothers delivered to the CVS board of directors separate oral

    56





    opinions, which opinions were confirmed by delivery of separate written opinions dated January 16, 2007, to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken described in each such opinion, the exchange ratio provided for in the merger was fair, from a financial point of view, to CVS, after giving effect to the payment of the Caremark special cash dividend.

         Evercore’s and Lehman Brothers’ opinions dated January 16, 2007, the full texts of which describe the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Evercore and Lehman Brothers, are attached as Annex D and Annex E, respectively, and are incorporated into this document by reference. Evercore’s and Lehman Brothers’ opinions were directed only to the fairness to CVS, from a financial point of view, of the exchange ratio provided for in the merger and do not address any other aspect of the merger. The opinions do not address the relative merits of the merger as compared to other business strategies or transactions that might be available with respect to CVS or CVS’ underlying business decision to effect the merger. The opinions do not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the merger. Holders of CVS common stock are encouraged to read the opinions carefully in their entirety. The summaries of Evercore’s and Lehman Brothers’ opinions described below are qualified in their entirety by reference to the full texts of the opinions.

    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 January 16, 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 January 16, 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 Annex D 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. Stockholders should read the opinion carefully and in its entirety.

         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.

    Summary of Evercore's January 16, 2007 Fairness Opinion

          The following is a summary of Evercore's January 16, 2007 opinion and the methodology that Evercore used to render its opinion. The summary is qualified in its entirety by reference to the full text of the opinion.

         In arriving at its opinion, Evercore, among other things:

    • analyzed certain publicly available financial statements and other publicly available business information including Wall Street research analyst reports relating to CVS and Caremark that Evercore deemed relevant to its analysis;

    • analyzed certain internal non-public financial and operating data concerning CVS and Caremark prepared and furnished to Evercore by the management of each of CVS and Caremark, respectively;

    • analyzed certain financial projections concerning Caremark for 2006 and 2007 furnished to Evercore by the management of Caremark and certain financial projections concerning CVS for 2006 and 2007 furnished to Evercore by the management of CVS;

    57





    • reviewed the amount and timing of the synergies expected to result from the merger as well as the transaction expenses and one-time cash costs arising from the proposed transaction (which Evercore refers to as “integration costs”), both as estimated by the management of CVS and furnished to Evercore by CVS;

    • discussed the past and current operations and financial condition and the prospects of CVS and Caremark with the management of each of CVS and Caremark, respectively;

    • reviewed the reported prices and trading activity of the Caremark common stock and the CVS common stock;

    • compared the financial performance of Caremark and the prices and trading activity of the Caremark common stock with that of selected publicly traded companies and their securities;

    • compared the financial performance of CVS and the prices and trading activity of CVS common stock with that of selected publicly traded companies and their securities;

    • compared the proposed financial terms of the merger with publicly available financial terms of certain transactions that Evercore deemed reasonably comparable to the merger;

    • considered the potential financial impact of CVS’ contemplated accelerated share repurchase program expected to be effected as promptly as practicable after the effective time of the merger as described in the CVS waiver agreement;

    • considered the potential pro forma impact of the merger on CVS, based on inputs and analysis provided by CVS management;

    • reviewed the merger agreement and a draft of Amendment No. 1 to the merger agreement dated January 15, 2007, which Evercore assumed was in substantially final form and would not vary in any respect material to its analysis;

    • reviewed a draft dated January 15, 2007 of the CVS waiver agreement which Evercore assumed was in substantially final form and would not vary in any respect material to its analysis; and

    • performed such other analyses and examinations and considered such other factors as Evercore in its sole judgment deemed appropriate for purposes of its opinion.

         For purposes of its analyses and opinion, Evercore relied upon and assumed, without assuming any responsibility for independently verifying, the accuracy and completeness of all the financial and other information that was publicly available or was furnished to Evercore by Caremark or CVS or otherwise discussed with or reviewed by or for Evercore, and it has not assumed any liability therefor. Evercore further relied upon the assurances of the management of CVS and Caremark, respectively, that they were not aware of any facts that would make such information inaccurate or misleading. Evercore did not make nor assume any responsibility for making any valuation or appraisal of any assets or liabilities of CVS or Caremark, nor were any such valuations or appraisals provided to Evercore.

         With respect to the CVS projections provided to Evercore by CVS management and the Caremark projections provided to Evercore by Caremark management, Evercore assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of each of the management of CVS and Caremark, respectively, as to future financial performance. With the consent of the management of CVS, Evercore relied on certain publicly available Wall Street research analyst projections for forecasted financial results for CVS and Caremark in both 2008 and 2009. With respect to the synergies expected to result from the merger and integration costs estimated by the management of CVS to result from the merger, Evercore assumed that the timing and amounts of such synergies and integration costs were reasonable. Evercore expressed no view as to such financial analyses and forecasts, the synergies and the integration costs or the assumptions on which they were based. Evercore also assumed that the merger would qualify as a tax-free reorganization for United States federal income tax purposes, and that the merger and the other transactions contemplated by the merger agreement would be consummated as described in the merger agreement and without any waiver, amendment or modification of any terms or conditions that would have been material to Evercore’s opinion. Evercore further assumed that all required governmental, regulatory or other consents and approvals necessary for the consummation of the merger have been

    58





    and would be obtained without any of the changes described in Section 8.01(a) of the merger agreement. Evercore has also assumed that the Caremark special cash dividend would be paid upon the occurence of the effective time of the merger.

         Evercore’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to Evercore as of, January 16, 2007. It should be understood that subsequent developments may affect Evercore’s opinion and that Evercore does not have any obligation to update, revise, or reaffirm its opinion. Evercore’s opinion was limited to the fairness, from a financial point of view, to CVS of the exchange ratio. Evercore expressed no opinion as to the price at which CVS common stock would trade at any future time.

         CVS engaged Evercore to act as a financial advisor based on its qualifications, experience and reputation and its knowledge of the business of CVS. Evercore is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses in connection with mergers and acquisitions, leveraged buyouts, competitive biddings, private placements and valuations for corporate and other purposes.

         Evercore acted as financial advisor to CVS with respect to the proposed merger pursuant to a letter agreement dated April 21, 2006 and will receive a fee from CVS for its services, the principal portion of which is contingent upon consummation of the merger. CVS has agreed to reimburse Evercore’s expenses and to indemnify Evercore against certain liabilities arising out of its engagement, including certain liabilities under the federal securities laws. In addition, Evercore advised CVS on its purchase of Albertson's standalone drugstores in 2006 and advised CVS on its purchase of selected Eckerd assets in 2004 and received customary fees for its services. In the ordinary course of business, the affiliates of Evercore Group L.L.C. may actively trade the debt and equity securities, or options on securities, of CVS or Caremark, for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

         Financial Analysis

         The following is a summary of the material financial analyses performed by Evercore in connection with the preparation of its opinion delivered to the CVS board of directors on January 16, 2007. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Evercore, the tables must be read together with the text of each summary. Considering any portion of such analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Evercore’s opinion.

         Historical Share Price Analysis

         Evercore considered historical data with regard to the trading prices of CVS and Caremark common stock for the one-year period prior to and including October 31, 2006, the last trading day prior to announcement of the transaction. During this period, the closing stock price of CVS common stock ranged from a low of $23.89 to a high of $36.14 per share, and the closing price of Caremark ranged from a low of $42.40 to a high of $59.89 per share. The foregoing historical share price analysis was presented to the CVS board of directors to provide it with background information and perspective with respect to the relative historical share prices of CVS and Caremark common stock.

          Historical Exchange Ratio Analysis

         Evercore compared the historical per share prices of CVS common stock and Caremark common stock for different periods during the three years prior to and including October 31, 2006, the last trading day prior to announcement of the transaction, in order to determine the average implied exchange ratio that existed for those periods. The following table indicates the average exchange ratio (after giving effect to the payment of the Caremark special cash dividend), of CVS common stock for Caremark common stock for the periods indicated:

        Implied Exchange
    Ratio

    January 12, 2007   1.717x
    Unaffected Period

    2 Month average   1.617x
    3 Month average   1.612x
    6 Month average   1.587x
    1 Year average   1.647x
    2 Year average   1.588x
    3 Year average   1.541x

         Equity Research Analysis

         Evercore compared recent publicly available research analyst price targets from firms that published price targets for CVS or Caremark as of October 31, 2006, the last trading day prior to the announcement of the transaction.

         Evercore calculated the mean and median target price for each of the CVS common stock and the Caremark common stock based on the analysts’ price targets. The analysis yielded mean and median share price targets for CVS of $39.47 and $40.00, respectively. Similar analysis for Caremark yielded mean and median share price targets of $63.96 and $62.00, respectively.

         Peer Group Trading Analysis

         In order to assess how the public market values shares of similar publicly traded companies, Evercore reviewed and compared specific financial and operating data relating to each of CVS and Caremark with selected companies that Evercore deemed to have certain characteristics that are similar to those of CVS and Caremark, respectively. As part of its peer group trading analysis, Evercore calculated and analyzed the ratio of current stock price to estimated 2007 earnings per share (commonly referred to as a price earnings ratio, or P/E) for CVS and Caremark, respectively, and each member of its respective peer group. Evercore also calculated and analyzed the ratio of enterprise value to estimated 2007 earnings before interest, taxes, depreciation and amortization (or, EBITDA) for CVS and Caremark, respectively, and each member of its respective peer group. The enterprise value of each company was obtained by adding its short and long term debt, to the sum of the market value of its common equity, and the book value of any minority interest, and subtracting its cash and cash equivalents and market value of unconsolidated investments. All of these calculations were performed based on closing prices as of October 31, 2006, (the last trading day prior to announcement of the transaction) and as of January 12, 2007 (the last trading date prior to the delivery of Evercore’s opinion).

         CVS

         The companies that Evercore deemed to have certain characteristics that are similar to those of CVS were Walgreens, Shoppers Drug Mart, Jean Coutu Group, Rite Aid and Longs Drug Stores.

         The analysis of current stock price to earnings as of October 31, 2006 indicated that, for the selected peer group, the ratio of current stock price to estimated 2007 earnings per share ranged from 19.6x to 20.9x. This compared to a current stock price as a multiple of estimated 2007 earnings per share ratio of 16.6x for CVS, based on publicly available research estimates as of October 31, 2006.

         The analysis of financial multiples as of October 31, 2006 indicated that, for the selected peer group, enterprise value as a multiple of estimated 2007 EBITDA ranged from 7.3x to 11.7x. This compared to enterprise value as a multiple of estimated 2007 EBITDA of 8.7x for CVS, based on publicly available research estimates as of October 31, 2006.

         The analysis of current stock price to earnings as of January 12, 2007 indicated that, for the selected peer group, the ratio of current stock price to estimated 2007 earnings per share ranged from 20.0x to 23.2x. This compared to a

    60





    current stock price as a multiple of estimated 2007 earnings per share ratio of 17.0x for CVS, based on publicly available research estimates as of January 12, 2007.

         The analysis of financial multiples as of January 12, 2007 indicated that, for the selected peer group, enterprise value as a multiple of estimated 2007 EBITDA ranged from 7.8x to 13.3x. This compared to enterprise value as a multiple of estimated 2007 EBITDA of 9.0x for CVS, based on publicly available research estimates as of January 12, 2007.

         Using a selected multiple range of 17.0x to 20.0x estimated 2007 earnings per share, the peer group trading analysis of CVS yielded an implied valuation range for the CVS common stock of $31.89 to $37.52 per share. Using selected multiples of 8.5x to 9.5x estimated 2007 EBITDA, the peer group trading analysis yielded an implied valuation range for CVS common stock of $29.94 to $34.29 per share.

         Caremark

         The companies that Evercore deemed to have certain characteristics that are similar to those of Caremark were Medco Health Solutions and Express Scripts.

         The analysis of current stock price to earnings as of October 31, 2006 indicated that, for the selected peer group, the ratio of current stock price to estimated 2007 earnings per share ranged from 16.6x to 17.1x. This compared to a current stock price as a multiple of estimated 2007 earnings per share ratio of 17.4x for Caremark, based on publicly available IBES research estimates as of October 31, 2006.

         The analysis of financial multiples as of October 31, 2006 indicated that, for the selected peer group, enterprise value as a multiple of estimated 2007 EBITDA ranged from 9.4x to 10.1x. This compared to enterprise value as a multiple of estimated 2007 EBITDA of 9.7x for Caremark, based on publicly available research estimates as of October 31, 2006.

         The analysis of current stock price to earnings as of January 12, 2007 indicated that, for the selected peer group, the ratio of current stock price to estimated 2007 earnings per share ranged from 16.4x to 18.6x. This compared to a current stock price as a multiple of estimated 2007 earnings per share ratio of 20.1x for Caremark, based on publicly available IBES research estimates as of January 12, 2007.

         The analysis of financial multiples as of January 12, 2007 indicated that, for the selected peer group, enterprise value as a multiple of estimated 2007 EBITDA was 10.2x for both selected peers. This compared to enterprise value as a multiple of estimated 2007 EBITDA of 11.3x for Caremark, based on publicly available research estimates as of January 12, 2007.

         Using a selected multiple range of 17.0x to 20.0x estimated 2007 earnings per share, the peer group trading analysis of Caremark yielded an implied valuation range for the Caremark common stock of $48.16 to $56.66 per share. Using selected multiples of 9.5x to 10.5x estimated 2007 EBITDA, the peer group trading analysis of Caremark yielded an implied valuation range for Caremark common stock of $48.23 to $53.09 per share.

         Evercore calculated implied exchange ratios by taking the minimum Caremark implied share price over the average CVS implied share price, and the maximum Caremark implied share price over the average CVS implied share price. Based on the peer group trading analysis for both CVS and Caremark, Evercore calculated implied exchange ratios after giving effect to the payment of the Caremark special cash dividend ranging from 1.383x to 1.583x.

         Evercore selected the peer groups above because their businesses and operating profiles are reasonably similar to that of CVS and Caremark, as applicable. However, because of the inherent differences between the businesses, operations and prospects of CVS and Caremark, on the one hand, and the businesses, operations and prospects of the selected peer groups on the other, no company is exactly the same as CVS or Caremark. Therefore, Evercore believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the peer group trading analysis. Accordingly, Evercore also made qualitative judgments concerning differences between the financial and operating characteristics and prospects of CVS and Caremark and the companies included in the peer

    61






    group trading analysis that would affect the public trading values of each company in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between CVS and Caremark, on the one hand, and the companies included in the peer group trading analysis.

         Contribution Analysis

         Evercore analyzed the respective contributions of CVS and Caremark to estimated 2007 and 2008 EBITDA and Net Income of the combined company based on projections prepared by CVS management and Caremark management for 2007 and certain publicly available Wall Street research estimates for 2008. The analysis excludes the effect of expected synergies, integration costs and other financial effects of the transaction. Evercore also analyzed the respective contributions based on the market value of each of CVS and Caremark as of October 31, 2006, the last trading day prior to announcement of the transaction. Evercore used the contributions to calculate an implied exchange ratio. In doing this for EBITDA contributions, Evercore made certain adjustments to reflect the capital structures of CVS and Caremark. The contribution analysis indicated the following relative contributions of CVS and Caremark and the following implied exchange ratios after giving effect to the payment of the Caremark special cash dividend:

        Contribution

    Metric   10/31/06     2007E   2008E







    EBITDA                  
    CVS         63.5 %   63.6 %

    Implied exchange ratio   1.505 x            

         Precedent Transaction Analysis

         Using publicly available information, Evercore reviewed and compared the purchase prices and financial multiples paid in acquisitions of companies that Evercore, based on its experience with merger and acquisition transactions, deemed relevant to arriving at its opinion. Evercore performed the analysis for both CVS and Caremark. Evercore chose the transactions used in the precedent transaction analysis based on the similarity of the target companies in the transactions to CVS and Caremark, as applicable. However, no precedent transaction is identical to the merger. As a result, these analyses are not purely mathematical, but also take into account differences in financial and operating characteristics of the subject companies and other factors that could affect the transactions to which the merger is being compared.

         Evercore reviewed the following transactions in the precedent transaction analysis for CVS:

         Using a selected multiple range of 8.0x to 11.0x estimated 2006 EBITDA, the precedent transaction analysis of CVS yielded an implied valuation range for the CVS common stock of $21.81 to $32.64 per share. CVS estimated 2006 EBITDA does not reflect the full year pro forma results for the Albertson’s purchase. Therefore, Evercore also performed precedent transaction analysis for CVS using estimated 2007 EBITDA (which includes a full year impact of the Albertson’s transaction) and discounted the resulting share price for one year at an assumed cost of equity of 11% resulting in an implied valuation range for the CVS common stock of $27.42 to $40.35 per share.

         Using a selected multiple range of 10.0x to 14.0x estimated 2006 EBITDA, the precedent transaction analysis of Caremark yielded an implied valuation range for Caremark common stock of $44.81 to $61.93 per share. Evercore calculated implied exchange ratios by taking the minimum Caremark implied share price over the average CVS implied share price, and the maximum Caremark implied share price over the average CVS implied share price.

         Evercore calculated implied exchange ratios after giving effect to the payment of the Caremark special cash dividend based on the precedent transaction analysis ranging from 1.401x to 1.962x.

         Premia Paid Analysis

         Evercore reviewed the premia paid in all all-stock transactions valued at greater than $10 billion during the period from October 31, 2001 to January 12, 2007. Evercore calculated the premium per share paid by the acquirer compared to the share price of the target company prevailing one day, one week and four weeks prior to the announcement of the transaction, producing mean premia of 12.7%, 13.78% and 16.6’%, respectively, and median premia of 11.0%, 14.2% and 17.2%, respectively.

    63






         Evercore also reviewed the premia paid in all all-stock transactions valued at greater than $1 billion with pro forma acquirer ownership between 40%-60% since January 1, 2000. Evercore calculated the premium per share paid by the acquirer compared to the share price of the target company prevailing one day, one week and four weeks prior to the announcement of the transaction. All transactions since January 1, 2000 result in mean premia of 20.8%, 22.2% and 21.0% respectively, and median premia of 13.9%, 16.8% and 10.4%, respectively. To evaluate a more recent trend of transaction premia paid, a separate analysis of transactions since January 1, 2001 was considered. All transactions since January 1, 2001 produce mean premia of 6.7%, 5.5% and 7.2%, respectively, and median premia of 7.5%, 6.9% and 8.9%, respectively.

         Based on the assumptions set forth above, the premia paid analysis using a premia paid range of 0% to 20% yielded implied exchange ratios after giving effect to the payment of the Caremark special cash dividend ranging from 1.505x to 1.806x.

         Discounted Cash Flow Analysis

         Evercore performed a discounted cash flow analysis for each of CVS and Caremark by adding (1) the present value of such company’s projected after-tax unlevered free cash flows for fiscal year 2007 based on such company’s management estimates, and for fiscal years 2008 through 2009 based on certain publicly available Wall Street research estimates and (2) the present value of the “terminal value” of such company as of December 31, 2009. “Terminal value” refers to the estimated value of all future cash flows from an asset at a particular point in time.

         A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows of the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macro-economic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors. Evercore analyzed cash flows over a three year period due to the availability of one year of management estimates and the limited availability of Wall Street research estimates following such three year period. Based on Evercore’s judgment and expertise in performing such analysis, Evercore deemed a three year period to be a reasonable period in this context.

         Evercore estimated a range of CVS terminal values in 2009 based on certain publicly available Wall Street research estimates for EBITDA and selected trailing EBITDA exit multiples of 9.5x to 10.5x. Evercore estimated a range of Caremark terminal values in 2009 based on certain publicly available Wall Street research estimates for EBITDA and selected trailing EBITDA multiples from 11.0x to 12.0x. For each of CVS and Caremark, Evercore discounted the unlevered free cash flow streams and the estimated terminal value to a present value at discount rates ranging from 9.0% to 11.0% . The discount rates utilized in this analysis were chosen by Evercore based on the industry and also on an analysis of the weighted average cost of capital of CVS and Caremark, as applicable, and other companies in such company’s peer group. Evercore calculated per share equity values by first determining a range of enterprise values of CVS and Caremark, as applicable, by adding the present values of the after-tax unlevered free cash flows and terminal values for each EBITDA terminal multiple and discount rate scenario, and then subtracting from the enterprise values the net debt (which is total debt minus cash) of such company, and dividing those amounts by the number of fully diluted shares of such company.

         Based on the projections and assumptions set forth above, the discounted cash flow analysis of CVS yielded an implied valuation range for CVS common stock of $37.19 to $43.61 per share, and the discounted cash flow analysis of Caremark yielded an implied valuation range for Caremark common stock of $62.46 to $70.50 per share.

         Evercore calculated implied exchange ratios by taking the minimum Caremark implied share price over the average CVS implied share price, and the maximum Caremark implied share price over the average CVS implied share price. Based on the discounted cash flow analysis for both CVS and Caremark Evercore calculated implied exchange ratios (after giving effect to the payment of the Caremark special cash dividend) ranging from 1.497x to 1.695x, excluding the impact of any synergies or integration costs.

    64






         Pro Forma Analysis

         In order to evaluate the estimated ongoing impact of the merger, Evercore analyzed the pro forma earnings impact of the merger from the perspective of CVS stockholders assuming the merger closes March 31, 2007. For the purposes of this analysis, Evercore assumed (1) a $55.34 per share price for Caremark common stock acquired pursuant to the 1.670 exchange ratio (after giving effect to the payment of the Caremark special cash dividend) and the merger, (2) a $31.94 per share price for CVS common stock (the closing market price per share on January 12, 2007), (3) a transaction structure with 100% stock consideration, (4) financial forecasts for each company from each management for 2007 and certain publicly available Wall Street research estimates for 2008, and (5) synergy, integration costs and purchase accounting adjustments in accordance with CVS management estimates, and (6) accelerated share repurchase of 150 million shares effected by the pro forma combined company after closing. Evercore estimated that, based on the assumptions described above, the pro forma impact of the transaction on the earnings per share of CVS would be approximately 1.4% dilutive to 2007 earnings per share, and approximately 6.2% accretive to 2008 earnings per share. The financial forecasts that underlie this analysis are subject to substantial uncertainty and, therefore, actual results may be substantially different.

         General

         In connection with the review of the merger by the CVS board of directors, Evercore performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Evercore considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, Evercore believes that the summary provided and the analyses described above must be considered as a whole and that selecting any portion of its analyses, without considering all of them, would create an incomplete view of the process underlying its analyses and opinion.

         In performing its analyses, Evercore made numerous assumptions with respect to risks associated with industry performance, general business and economic conditions and other matters, many of which are beyond the control of CVS or Caremark. Any estimates contained in these analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. No limitations were imposed by CVS on the scope of Evercore’s investigations or the procedures followed by Evercore in rendering its opinion.

       Opinion of Lehman Brothers Inc.

         In September 2006, Lehman Brothers began assisting the CVS board of directors as its financial advisor with respect to pursuing a strategic combination with Caremark, and on November 1, 2006, the CVS board of directors entered into a written engagement agreement with Lehman Brothers. On November 1, 2006, Lehman Brothers rendered its oral opinion (subsequently confirmed in writing) to the CVS board of directors that as of such date and, based upon and subject to the matters stated in its opinion, from a financial point of view, the exchange ratio to be paid in the merger was fair to CVS. Thereafter, at the request of the CVS board of directors, in connection with the board of directors’ review of the amended terms of the transaction, on January 16, 2007, Lehman Brothers rendered its oral opinion (subsequently confirmed in writing) to the CVS board of directors that as of such date and, based upon and subject to the matters stated in its opinion, from a financial point of view, the exchange ratio to be paid in the merger was fair to CVS, after giving effect to the payment of the Caremark special cash dividend

         The full text of Lehman Brothers’ written opinion, dated January 16, 2007, is attached as Annex E to this joint proxy statement-prospectus. Stockholders are encouraged to read Lehman Brothers’ opinion carefully in its entirety for a description of the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion.

         Lehman Brothers’ advisory services and opinion were provided for the information and assistance of the CVS board of directors in connection with its consideration of the merger and Amendment No. 1 to the merger agreement. Lehman Brothers’ opinion is not intended to be and does not constitute a recommendation to any stockholder of CVS as to how such stockholder should vote in connection with the merger. Lehman Brothers was

    65






    not requested to opine as to, and Lehman Brothers’ opinion does not address, CVS’ underlying business decision to proceed with or effect the merger.

         The following is a summary of Lehman Brothers’ January 16, 2007 opinion and the methodology that Lehman Brothers used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

         In arriving at its opinion, Lehman Brothers reviewed and analyzed, among other things:

    • the merger agreement, as amended, and the specific terms of the merger;


    • publicly available information concerning CVS that Lehman Brothers believed to be relevant to its analysis, including CVS’ Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and CVS’ Quarterly Report on Form 10-Q for the quarters ended April 1, 2006, July 1, 2006 and September 30, 2006;


    • publicly available information concerning Caremark that Lehman Brothers believed to be relevant to its analysis, including Caremark’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and Caremark’s Quarterly Report on Form 10-Q for the quarters ended March 31, 2006, June 30, 2006 and September 30, 2006;


    • financial and operating information with respect to the business, operations and prospects of CVS furnished to Lehman Brothers by CVS, including (i) financial projections for CVS prepared by CVS’ management through December 31, 2007 and (ii) updated estimates of the amounts and timing of the cost savings, operating synergies (the “Updated Estimated Synergies”) and other strategic benefits expected by the management of CVS to result from a combination of the businesses of CVS and Caremark, including to reflect the Caremark special cash divided and accelerated share repurchase;


    • financial and operating information with respect to the business, operations and prospects of Caremark furnished to Lehman Brothers by Caremark, including financial projections for Caremark prepared by Caremark’s management through December 31, 2007;


    • the trading histories of CVS Common Stock and Caremark Common Stock from October 31, 2006 to January 12, 2007, and a comparison of those trading histories with each other and with those of other companies that Lehman Brothers deemed relevant;


    • a comparison of the historical financial results and present financial condition of CVS and Caremark with each other and with those of other companies that Lehman Brothers deemed relevant;


    • published estimates of independent equity research analysts with respect to the future financial performance of CVS and Caremark, adjusted to reflect the payment of the Caremark special cash dividend;


    • the relative contributions of CVS and Caremark to the historical and future financial performance of the combined company on a pro forma basis, reflecting the payment of the Caremark special cash dividend;


    • a comparison of the financial terms of the proposed transaction with the financial terms of certain other transactions that Lehman Brothers deemed relevant, and


    • the potential pro forma impact of the proposed transaction on the future financial condition and performance of CVS, including the Updated Estimated Synergies and the accelerated share repurchase transaction and the effect on CVS’ pro forma earnings per share.

    66






         In addition, Lehman Brothers had discussions with the managements of CVS and Caremark concerning their respective businesses, operations, assets, financial conditions and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate.

         In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by Lehman Brothers without assuming any responsibility for independent verification of such information. Lehman Brothers further relied upon the assurances of the managements of CVS and Caremark that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of CVS and Caremark, upon advice of CVS and Caremark, Lehman Brothers assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of CVS and Caremark as to their respective future financial performance and that they would perform substantially in accordance with such projections. With respect to the Updated Estimated Synergies, Lehman has assumed that the amount and timing of Updated Estimated Synergies are reasonable and, upon the advice of CVS, Lehman also has assumed that the Updated Estimated Synergies will be realized substantially in accordance with such estimates. In arriving at its opinion, Lehman Brothers did not conduct or obtain any evaluations or appraisals of the assets or liabilities of CVS or Caremark, nor did it conduct a physical inspection of the properties and facilities of CVS and Caremark. Lehman Brothers’ opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, January 16, 2007.

         The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its January 16, 2007 opinion to the CVS board of directors. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Lehman Brothers, the tables must be read together with the text of each summary. Considering any portion of such analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Lehman Brothers’ opinion.

         Historical Share Price Analysis

         Lehman Brothers considered historical data with regard to the trading prices of CVS and Caremark common stock for the period from January 12, 2004 to January 12, 2007. Lehman Brothers also considered the relative stock price performances during the period from January 12, 2006 to January 12, 2007 of (1) CVS, (2) Caremark, (3) an index of drugstore equities (“Drugstore Index”) comprised of the common stocks of Longs Drugs, Rite Aid, Shoppers Drug Mart and Walgreens and (4) an index of pharmacy benefit managers equities (“PBM Index”) comprised of the common stocks of Express Scripts and Medco.

         Lehman Brothers noted that during this one-year period, the share price of CVS common stock increased 18.3%, which outperformed the Drugstore Index, and the common stock of Caremark increased 10.5%, which outperformed the PBM Index.

         Historical Exchange Ratio Analysis

         Lehman Brothers also compared the historical per share prices of CVS and Caremark during different calendar periods during the one-year period prior to January 12, 2007 in order to determine the implied average exchange ratio that existed for those calendar periods (excluding the Caremark special cash dividend). The following table indicates the average exchange ratio of CVS common stock for Caremark common stock for the calendar periods indicated:

    Calendar Period   Average Exchange Ratio  



    January 12, 2007   1.717 x
    10-day period   1.734 x
    20-day period   1.747 x
    30-day period   1.739 x
    60-day period   1.656 x
    90-day period   1.621 x
    180-day period   1.619 x
    One-year period   1.608 x

    67






         Research Analyst Stock Price Targets

         Lehman Brothers reviewed publicly availably research reports published by various firms with respect to CVS and Caremark and observed that the range of analyst share price targets, which represent future share price targets over the next 12 months, was $38.00 to $41.00 for CVS, and $56.00 to $64.00 for Caremark, which reflects the payment of the Caremark special cash dividend. Lehman Brothers further observed that (1) CVS’ per share price as of January 12, 2007, represented a discount of (A) 15.9% to the analyst low price target of CVS and (B) 22.1% to the analyst high price target of CVS and (2) Caremark’s per share price, which reflects the payment of the Caremark special cash dividend, as of January 12, 2007, represented a discount of (A) 2.1% to the analyst low price target of Caremark and (B) 14.3% to the analyst high price target of Caremark.

         Comparable Company Analysis

         CVS

         In order to assess how the public market values shares of similar publicly traded companies, Lehman Brothers, based on its experience with companies in the drugstore industry, reviewed and compared specific financial and operating data relating to CVS with the following selected companies that Lehman Brothers deemed comparable to CVS, including:

    • Longs Drugs;


    • Rite Aid


    • Shoppers Drug Mart; and


    • Walgreens.

         As part of its comparable company analysis, Lehman Brothers calculated and analyzed CVS’ and each comparable company’s ratio of current stock price to its projected earnings per share (commonly referred to as a price earnings ratio, or P/E). Lehman Brothers also calculated and analyzed various financial multiples, including CVS’ and each comparable company’s enterprise value to certain projected financial criteria (such as EBITDA). The enterprise value of each company was obtained by adding its short- and long-term debt to the sum of the market value of its common equity and subtracting its cash and cash equivalents. All of these calculations were performed, and based on publicly available financial data (including First Call and Wall Street research estimates) and closing prices, as of January 12, 2007, the last trading date prior to the delivery of Lehman Brothers’ January 16, 2007 opinion. Using a selected multiple range of 18.0x to 20.0x 2007 estimated earnings per share and selected multiples of 9.5x to 11.5x 2006 estimated EBITDA, the peer group trading analysis of CVS yielded an implied valuation range for CVS common stock of $27.54 to $37.77 per share. The following presents the results of this analysis:

        2006E   2007E




    Enterprise Value/EBITDA            
     (excluding CVS, unless where noted)            
             High   14.9 x   13.9 x
             Low   8.5 x   7.6 x
             Mean   12.9 x   11.5 x
             CVS   10.8 x   8.9 x
    P/E (excluding CVS, unless where noted)            
             High   25.3 x   21.7 x
             Low   NM     NM  
             Mean   23.9 x   20.8 x
             CVS   20.6 x   16.9 x
                 
             Caremark            

    68






         In order to assess how the public market values shares of similar publicly traded companies, Lehman Brothers, based on its experience with companies in the pharmacy benefit management industry, reviewed and compared specific financial and operating data relating to Caremark with the following selected companies that Lehman Brothers deemed comparable to Caremark, including:

    • Express Scripts; and


    • Medco

         As part of its comparable company analysis, Lehman Brothers calculated and analyzed Caremark’s and each comparable company’s P/E ratio. Lehman Brothers also calculated and analyzed various financial multiples, including Caremark’s and each comparable company’s enterprise value to certain projected financial criteria such as EBITDA. All of these calculations were performed, and based on publicly available financial data (including First Call and Wall Street research estimates) and closing prices, as of January 12, 2007, the last trading date prior to the delivery of Lehman Brothers’ January 16, 2007 opinion. Using a selected multiple range of 16.0x to 20.0x 2007 estimated earnings per share and selected multiples of 10.5x to 11.5x 2006 estimated EBITDA, and after taking into account the payment of the Caremark special cash dividend, the peer group trading analysis of Caremark yielded an implied valuation range for Caremark common stock of $44.53 to $56.16. The following presents the results of this analysis:

        2006E   2007E




    Enterprise Value/EBITDA (excluding Caremark, unless where noted)            
             High   11.6 x   10.2 x
             Low   11.3 x   10.1 x
             Mean   11.5 x   10.1 x
             Caremark   12.2 x   10.7 x
    P/E (excluding Caremark, unless where noted)

             Mean   22.6 x   18.7 x
             Caremark   22.7 x   19.4 x

         Lehman Brothers selected the comparable companies above because their businesses and operating profiles are reasonably similar to that of CVS and Caremark, respectively. However, because of the inherent differences between the business, operations and prospects of CVS and Caremark and the businesses, operations and prospects of the selected comparable companies, no comparable company is exactly the same as CVS or Caremark, respectively. Therefore, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the comparable company analyses. Accordingly, Lehman Brothers also made qualitative judgments concerning differences between the financial and operating characteristics and prospects of CVS and Caremark and the companies included in the comparable company analyses that would affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analyses. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between CVS and Caremark and the companies included in the comparable company analyses.

         Comparable Transaction Analysis

         Selected Drugstore Transactions

         Using publicly available information, Lehman Brothers reviewed and compared the purchase prices and financial multiples paid in ten acquisitions that took place within the drugstore industry, of companies that Lehman Brothers, based on its experience with merger and acquisition transactions, deemed relevant to arriving at its opinion. Lehman Brothers chose the transactions used in this analysis based on the similarity of the target companies in the transactions to CVS in the size, mix, margins and other characteristics of their businesses. Lehman Brothers reviewed the following transactions:

         Based on publicly available information, Lehman Brothers considered, among other things, the enterprise value of each target company; the enterprise value of each target company as a multiple of the EBITDA of the target company in each case for the latest 12 months, which is referred to as LTM, prior to the date that the transaction was announced, and the premium to the one-day stock price offered in the transaction. Using the drugstore transactions selected, the mean of 11.1x LTM EBITDA yielded an implied valuation for CVS common stock of $33.28 per share.

         Selected Pharmacy Benefit Manager Transactions

         Using publicly available information, Lehman Brothers reviewed and compared the purchase prices and financial multiples paid in nine acquisitions that took place within the pharmacy benefit manager industry, of companies that Lehman Brothers, based on its experience with merger and acquisition transactions, deemed relevant to arriving at its opinion. Lehman Brothers chose the transactions used in the comparable transaction analysis based on the similarity of the target companies in the transactions to Caremark in the size, mix, margins and other characteristics of their businesses. Lehman Brothers reviewed the following transactions:

Using the pharmacy benefit manager transactions selected and after taking into account the payment of Caremark special cash dividend, the mean of 12.8x LTM EBITDA yielded an implied valuation for Caremark common stock of $55.36 per share. The following table sets forth the results of this analysis:

         Discounted Cash Flow Analysis

         As part of its analysis, and in order to estimate the present value of CVS and Caremark common stock, Lehman Brothers prepared a five-year discounted cash flow analysis for CVS and Caremark, calculated as of December 31, 2006, of after-tax unlevered free cash flows for fiscal years 2007 through 2011. Lehman Brothers’ decision to prepare a five-year Discounted Cash Flow analysis was based on Lehman Brothers’ expertise and familiarity with CVS and Caremark, and the drugstore and pharmacy benefit management industries generally, as well as generally accepted fundamental valuation methodologies for stable-growth companies like CVS and Caremark.

         A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of a business by calculating the “present value” of estimated future free cash flows of the business. “Present value” refers to the current value of future cash flows and is obtained by discounting those future cash flows by a discount rate that takes into account macro-economic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors. Lehman Brothers performed a discounted cash flow analysis for each of CVS and Caremark by adding (1) the present value of the applicable company’s projected after-tax unlevered free cash flows for fiscal years 2007 through 2011 to (2) the present value of the “terminal value” of the applicable company as of 2011. “Terminal value” refers to the value of all future free cash flows to be derived from a business at a particular point in time.

         CVS Discounted Cash Flow Analysis

         Lehman Brothers estimated, after taking into account selected comparable drugstores’ enterprise values to the last twelve months’ EBITDA multiples, a range of terminal values in 2011 calculated based on selected EBITDA multiples of 9.0x to 11.0x. Lehman Brothers discounted the unlevered free cash flow streams and the estimated terminal value to a present value at a range of discount rates from 9.5% to 11.5% . The discount rates utilized in this analysis were chosen by Lehman Brothers based on its expertise and experience with the drugstore industry and also on an analysis of the weighted average cost of capital of CVS and other comparable companies. Lehman Brothers calculated per share equity values by first determining a range of enterprise values of CVS by adding the present values of the after-tax unlevered free cash flows and terminal values for each EBITDA terminal multiple and discount rate scenario, and then subtracting from the enterprise values the net debt (which is total debt minus cash) of CVS, and dividing those amounts by the number of fully diluted shares of CVS.

         Based on the projections and assumptions set forth above, the discounted cash flow analysis of CVS yielded an implied valuation range of CVS common stock of $37.97 to $50.09 per share. Lehman Brothers noted that the price of CVS common stock as of January 12, 2007 was $31.94 per share, which was (i) 15.9% lower than the low of the per share equity valuation range implied by the foregoing analysis and (ii) 36.2% lower than the high of the per share equity valuation range implied by the foregoing analysis.

         Caremark Discounted Cash Flow Analysis

         Lehman Brothers estimated, after taking into account selected comparable pharmacy benefit managers’ enterprise values to the last twelve months’ EBITDA multiples, a range of terminal values in 2011 calculated based on selected last twelve months EBITDA multiples of 9.5x to 11.5x. Lehman Brothers discounted the unlevered free cash flow streams and the estimated terminal value to a present value at a range of discount rates from 8.5% to 10.5% . The discount rates utilized in this analysis were chosen by Lehman Brothers based on its expertise and experience with the pharmacy benefit management industry and also on an analysis of the weighted average cost of capital of Caremark and other comparable companies. Lehman Brothers calculated per share equity values by first determining a range of enterprise values of Caremark by adding the present values of the after-tax unlevered free cash flows and terminal values for each EBITDA terminal multiple and discount rate scenario, and then subtracting from the enterprise values the adjusted net debt of Caremark, taking into account the payment of the Caremark special cash dividend and dividing those amounts by the number of fully diluted shares of Caremark.

         Based on the projections and assumptions set forth above, the discounted cash flow analysis of Caremark yielded an implied valuation range of Caremark common stock of $55.05 to $68.95 per share. Lehman Brothers noted that after reducing the Caremark common stock price $2.00 to reflect the payment of the Caremark special cash dividend, the price of Caremark common stock as of January 12, 2007 was $54.83 per share, which was (i) 0.4% lower than the low of the per share equity valuation range implied by the foregoing analysis and (ii) 20.5% lower than the high of the per share equity valuation range implied by the foregoing analysis, (iii) 14.9% lower than the low of the per share equity valuation range after taking into account pro forma synergies, and (iv) 32.1% lower than the high of the per share equity valuation range after taking into account pro forma synergies.

         Contribution Analysis

         Lehman Brothers analyzed the respective contributions of CVS and Caremark to the estimated calendar years 2006 and 2007 EBITDA and net income of the combined company based on First Call and Wall Street research estimates. The proportionate contributions were calculated taking into account CVS’ and Caremark’s respective current debt and cash levels and payment of the Caremark special cash dividend, and compared to the pro forma ownership of the combined company by CVS and Caremark stockholders as a result of the merger. Based on the implied diluted equity ownership of each of CVS and Caremark stockholders of the combined company, Lehman Brothers calculated a range of implied exchange ratios. The following table sets forth the results of this analysis:

    72






        Imputed Diluted Ownership      

    Metric   CVS   Caremark   Implied
    Exchange Ratio







    EBITDA:                  
    2006E   57.1 %   42.9 %   1.496 x
    2007E   58.1 %   41.9 %   1.436 x
                       
    Net Income:                  
    2006E   55.6 %   44.4 %   1.586 x
    2007E   56.5 %   43.5 %   1.530 x
                       
    Equity Value at Merger Price   54.5 %   45.5 %   1.670 x

         Pro Forma Analysis

         In order to evaluate the estimated ongoing impact of the merger, Lehman Brothers analyzed the pro forma earnings effect of the merger from the perspective of CVS stockholders, after taking into account the payment of the Caremark special cash dividend and the accelerated share repurchase. For the purposes of this analysis, Lehman Brothers assumed (1) an exchange ratio of 1.67 shares of CVS common stock for each share of Caremark common stock acquired pursuant to the merger, (2) a $31.94 per share price for CVS common stock (the closing market price per share on January 12, 2007), (3) financial forecasts for each company from management of CVS and Caremark, (4) annual cost savings and synergies from the transaction of $170 million in the last three quarters of 2007 and $500 million of in 2008, as determined by the management of CVS, and (5) the retirement of 150 million shares pursuant to the accelerated share repurchase and the incurrence of approximately $5 billion of additional debt in connection with the accelerated share repurchase. Lehman Brothers estimated, based on the assumptions described above, and excluding certain non-recurring transaction costs incurred in connection with the merger, the pro forma impact of the transaction on the earnings per share of CVS would be accretive in 2007 and 2008. Lehman Brothers’ analysis assumed that Caremark contributed to the combined company’s financial results for nine months in 2007. The financial forecasts that underlie this analysis are subject to substantial uncertainty and, therefore, actual results may be substantially different.

         General

         In connection with the review of the merger and Amendment No. 1 to the merger agreement by the CVS board of directors, Lehman Brothers performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Lehman Brothers considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, Lehman Brothers believes that the summary provided and the analyses described above must be considered as a whole and that selecting any portion of its analyses, without considering all of them, would create an incomplete view of the process underlying its analyses and opinion. In addition, Lehman Brothers may have given various analyses and factors more or less weight than other analyses and factors and may have deemed various assumptions more or less probable than other assumptions, so that the ranges of valuations resulting from any particular analysis described above should not be taken to be Lehman Brothers’ view of the actual value of CVS or Caremark.

         In performing its analyses, Lehman Brothers made numerous assumptions with respect to industry risks associated with reserves, industry performance, general business and economic conditions and other matters, many of which are beyond the control of CVS or Caremark. Any estimates contained in Lehman Brothers’ analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. The analyses performed were prepared solely as part of Lehman Brothers’ analysis of the fairness from a financial point of view to CVS of the exchange ratio and were prepared in connection with the delivery by Lehman Brothers of its opinion, dated January 16, 2007, to the CVS board of directors. The analyses do not purport to be appraisals or to reflect the prices at which CVS common stock or Caremark common

    73






    stock might trade following announcement of the merger or the prices at which CVS common stock might trade following completion of the merger.

         The terms of the merger were determined through arm’s length negotiations between CVS and Caremark and were unanimously approved by the CVS and the Caremark boards of directors. Lehman Brothers did not recommend any specific exchange ratio or form of consideration to CVS or that any specific exchange ratio or form of consideration constituted the only appropriate consideration for the merger. Lehman Brothers’ opinion was provided to the CVS board of directors to assist it in its consideration of the exchange ratio in the merger. Lehman Brothers’ opinion does not address any other aspect of the proposed merger and does not constitute a recommendation to any stockholder as to how to vote or to take any other action with respect to the merger. Lehman Brothers’ opinion was one of the many factors taken into consideration by the CVS board of directors in making its unanimous determination to approve the merger agreement. Lehman Brothers’ analyses summarized above should not be viewed as determinative of the opinion of the CVS board of directors with respect to the value of CVS or Caremark or of whether the CVS board of directors would have been willing to agree to a different exchange ratio or form of consideration.

         Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The CVS board of directors selected Lehman Brothers because of its expertise, reputation and familiarity with CVS and the drugstore and pharmacy benefit management industry generally and because its investment banking professionals have substantial experience in transactions comparable to the merger.

         As compensation for its services in connection with the merger, CVS has agreed to pay Lehman Brothers a customary fee for its services, a portion of which is payable upon delivery of the fairness opinion and the remainder of which is contingent upon the completion of the transaction. Moreover, CVS has agreed to reimburse Lehman Brothers for reasonable out-of-pocket expenses incurred in connection with the merger and to indemnify Lehman Brothers for certain liabilities that may arise out of its engagement by CVS and the rendering of Lehman Brothers’ opinion. Lehman Brothers has performed various investment banking services for CVS in the past and has received customary fees for such services. These services included acting as a bookrunner on a number of CVS’ fixed income-related financings, acting as one of CVS’ commercial paper dealers, acting as a lender under certain of CVS’ credit facilities and acting as CVS’ advisor on several of its strategic activities. Lehman Brothers may continue to provide CVS and its affiliates with investment banking services and will receive customary fees for any such services provided. In addition, Lehman Brothers is currently a lender under one of CVS’ existing revolving credit facilities, and CVS has requested and Lehman Brothers has provided a commitment for a portion of the funds necessary to finance the accelerated share repurchase transaction for which Lehman Brothers will receive customary fees.

         In the ordinary course of its business, Lehman Brothers may actively trade in the debt or equity securities of CVS and Caremark for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

    Interests of CVS Executive Officers and Directors in the Merger

         In considering the recommendation of the CVS board of directors with respect to the merger, CVS stockholders should be aware that executive officers of CVS and members of the CVS board of directors may have interests in the transactions contemplated by the merger agreement that are different than, or in addition to, the interests of the CVS stockholders generally. The CVS board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and making its recommendation. These interests are summarized below.

         Board and Committee Composition of the Combined Company

         The following summarizes certain changes that will take effect at the effective time of the merger. Certain members of the CVS board of directors will continue as directors of the combined company. At the effective time, the board of directors of the combined company will be comprised of an equal number of individuals designated by

    74






    the CVS board and Caremark board, respectively. Mr. Ryan, currently the chairman of the board, president and chief executive officer of CVS, will serve as chief executive officer of the combined company and as a director on the board of the combined company.

         As of the effective time, the executive committee of the CVS/Caremark board of directors will be comprised of an equal number of individuals who, before the completion of the merger, were members of the CVS board of directors and individuals who, before the completion of the merger, were members of the Caremark board of directors. As of the effective time, the executive committee of the CVS/Caremark board of directors will consist of Thomas M. Ryan, E. Mac Crawford, one individual who, before completion of the merger, was a member of the CVS board of directors and one individual who, before completion of the merger, was a member of the Caremark board of directors.

         In addition, as of the effective time, the chairman of each of the combined company’s management, planning and development committee and the nominating and corporate governance committees will be an individual who, before completion of the merger, was a member of the CVS board of directors.

         Chief Executive Officer

         As of the effective time of the merger, Mr. Ryan will be the chief executive officer of the combined company. Any removal of Mr. Ryan as chief executive officer of the combined company before January 2010 will require the approval of three-quarters of the members of the board of directors of the combined company.

    Caremark Reasons for the Merger

         The Caremark board of directors unanimously approved the merger agreement and the transactions contemplated by it. In evaluating the merger, the Caremark board of directors consulted with Caremark’s management, as well as with Caremark’s legal and financial advisors. In reaching its conclusion to approve the merger agreement and the merger transactions, the Caremark board of directors considered a variety of factors weighing favorably towards the merger, including, without limitation, the material factors listed below:

  • Strategic Rationale. The fact that the merger is a merger of equals with complementary operations and capabilities of the combined company providing increased scale, a strong financial base and a diversified services portfolio necessary to increase stockholder value, enhance value to the customers and increase cost efficiencies. Specifically, it is anticipated that the merger would allow the combined company to:
     
     
  • capitalize on Caremark’s expertise in serving payors as one of the nation’s leading pharmaceutical services companies and on CVS’ expertise and reputation in serving consumers as one of the nation’s largest pharmacy chains;
     
     
  • provide end-to-end services from plan design analysis to prescription fulfillment;
     
     
  • achieve a financial base and scale capable of delivering enhanced value to customers in the fast changing healthcare environment;
     
     
  • drive value for plan sponsors through an enhanced ability to assist and provide information to plan participants and more effectively manage pharmacy costs;
     
     
  • improve clinical outcomes, resulting in better control over healthcare costs;
     
     
  • offer broader, innovative disease management, health assessment and wellness services to help consumers manage and protect against potential health risks and avoid future healthcare costs;
     
     
  • the companies’ shared vision of the evolution of healthcare services and the potential for the combined company to address a number of emerging trends in the healthcare industry, including an aging population, increasing incidence of chronic disease, greater availability of generic drugs, Medicare Part D and consumer directed health plans;
     

    75






     
  • the expanded growth opportunities for the combined company;
     
     
  • the combined company will put together CVS’ and Caremark’s complementary specialty pharmacy offerings to achieve a more comprehensive specialty pharmacy business in terms of diseases covered and will offer expanded distribution capability and patient access through its retail and mail services pharmacies; and
     
     
  • the impact of the merger on Caremark’s clients, plan participants, employees and other constituencies and the expectation that they would benefit from their association with a stronger combined company which could offer: (1) more effective cost management and innovative programs, (2) expanded choice for consumers with greater access, (3) more personalized healthcare services and (4) a dynamic work environment for employees with significantly expanded professional opportunities.
     
  • Strategic Alternatives. The strategic alternatives to the merger available to Caremark, including remaining a stand-alone entity and pursuing acquisitions of strategic assets and alternative acquisition candidates, and the determination of the Caremark board of directors that a merger of equals with CVS is expected to yield greater strategic benefits than other reasonably likely alternatives because of the factors described above in “Strategic Rationale”.
     
  • Financial Rationale.
     
     
  • The expected merger benefits, then estimated to be approximately $400 million in anticipated synergies primarily from increased purchasing and operating efficiencies. See “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” beginning on pages 38 and 27, respectively. The estimated $400 million in synergies was updated to in excess of $500 million as a result of the additional integration work completed since receiving antitrust clearance on December 20, 2006.
     
     
  • The financial performance and condition, business operations and prospects of each of Caremark, CVS and the combined company.
     
     
  • Caremark stockholders will own approximately 45.5% of the combined company immediately after the effective time of the merger, which will allow Caremark stockholders to participate in all of the benefits of the combined company, including future growth and expected synergies of the combined company.
     
     
  • The opportunity for Caremark stockholders to benefit from any increase in the trading of CVS common stock between announcement of the merger and the closing of the merger based on the fixed exchange ratio of 1.670 shares of CVS common stock for each share of Caremark common stock.
     
     
  • The expectation that the merger would allow the combined company to generate significant cash flows.
     
  • Governance Considerations.
     
     
  • The fact that the board of directors of the combined company will be split evenly between designees from the Caremark board of directors and designees from the CVS board of directors.
     
     
  • The fact that E. Mac Crawford will become chairman of the board of directors of the combined company.
     
     
  • The fact that, while the combined company’s headquarters would be located in Woonsocket, Rhode Island, the headquarters of the pharmacy services business would continue to be located in Nashville, Tennessee.
     

    76






     
  • The strong management team to be drawn from both Caremark and CVS that will manage the combined company, the complementary cultural fit and organizational structure of both companies and the demonstrated ability of both management of Caremark and management of CVS to integrate and obtain benefits from previous business combinations.
     
  • Tax Considerations. The ability to complete the merger as a tax-free reorganization for U.S. federal income tax purposes.
     
  • Opinions of Financial Advisors. UBS’ and JPMorgan’s separate opinions, each dated November 1, 2006, to Caremark’s board of directors as to the fairness, from a financial point of view and as of the date of the opinion, of the exchange ratio provided for in the merger, as more fully described in “—Opinions of Financial Advisors to Caremark” beginning on page 80.
     
  • Terms of the Merger Agreement.
     
     
  • The merger agreement permits Caremark, before the Caremark special meeting is held, to provide material non-public information to, engage in negotiations with and, in certain circumstances, enter into a conditional definitive agreement with, a third party that makes an acquisition proposal that is or is reasonably likely to lead to a superior proposal (as described in “The Merger Agreement—Certain Covenants—No Solicitation” beginning on page 110), on the terms and subject to the conditions of the merger agreement.
     
     
  • The circumstances under which the $675 million termination fee is payable under the merger agreement and the view of the Caremark board of directors that these provisions should not preclude bona fide alternative proposals involving Caremark; the fact that the termination fee provisions are reciprocal and the product of negotiations; and the fact that the size of the termination fee is reasonable in light of the size and benefits of the merger.
     
     
  • The fact that the representations, warranties and covenants of Caremark and CVS are reciprocal.
     
     
  • The retention and employee benefit arrangements provided in the merger agreement.
     
  • Regulatory Approvals. The regulatory approvals required to complete the merger, including expiration or termination of any waiting period or extension thereof under the HSR Act, and the belief of Caremark’s management that the merger would be approved by the requisite authorities, without the imposition of conditions sufficiently material to preclude or materially diminish the benefits expected from the merger, and would otherwise be consummated in accordance with the terms of the merger agreement.
     
  • Due Diligence. The results of Caremark’s due diligence review of CVS.

         The Caremark board of directors weighed the aforementioned material factors against a number of other factors identified in its deliberations that weighted negatively against the merger, including, without limitation, the following material factors:

  • the challenges inherent in the combination of two businesses of the size and scope of Caremark and CVS and the possible diversion of management attention for an extended period of time;
       
  • the risk of not capturing all of the anticipated synergies between Caremark and CVS relating to purchasing efficiencies and the risk that other anticipated benefits of the merger might not be realized;
       
  • because the exchange ratio is fixed, in the event of a decrease in the price of CVS common stock between the date of execution of the merger agreement and the closing of the merger, Caremark stockholders may receive less value for their shares upon the closing of the merger than calculated pursuant to the exchange ratio on the date of execution of the merger agreement and on the date of the Caremark special meeting;
       

    77






  • the limitations imposed in the merger agreement on the conduct by Caremark of its business and on the solicitation by Caremark of alternative business combinations prior to completion of the merger;
     
  • certain provisions of the merger agreement that could have the effect of discouraging proposals for alternative transactions involving Caremark, including:
     
     
  • the inability of Caremark to terminate the merger agreement in order to accept a superior alternative transaction from a third party;
     
     
  • the requirement that the Caremark board of directors submit the merger agreement and the merger to the Caremark stockholders for consideration at the special meeting notwithstanding the existence of a superior alternative transaction and the Caremark board of directors’ recommendation of such alternative transaction;
     
     
  • the restrictions on Caremark’s ability to solicit proposals for alternative transactions involving Caremark; and
     
     
  • the requirement that Caremark pay a termination fee of $675 million to CVS if CVS terminates the merger agreement because the Caremark board withdraws its recommendation of the merger or qualifies its recommendation in a manner adverse to CVS and the other circumstances under which the termination fee is payable by Caremark.
     
  • the prohibition in the merger agreement on the ability of the Caremark board to withdraw its recommendation of the merger or qualify its recommendation in a manner adverse to CVS other than in connection with Caremark’s receipt of a proposal for a superior alternative transaction involving Caremark;
     
  • the circumstances under which CVS may terminate the merger agreement, including if Caremark’s board withdraws its recommendation of the merger or qualifies its recommendation in a manner adverse to CVS;
     
  • the conditions to the merger agreement requiring receipt of certain regulatory approvals and clearances (see “Regulatory and Other Approvals Required for the Merger” beginning on page 102);
     
  • the additional potential problems and costs, including transaction costs associated with the merger;
     
  • the risk that the merger may not be completed despite the parties’ efforts or that the closing may be unduly delayed and the effects on Caremark as a stand-alone company because of such failure or delay; and
     
  • the other risks described in “Risk Factors” beginning on page 27.

         After consideration of these factors, the Caremark board of directors determined that these risks could be mitigated or managed by Caremark or CVS or by the combined company following the merger, were reasonably acceptable under the circumstances or, in light of the anticipated benefits, the risks were unlikely to have a materially adverse impact on the merger or on the combined company following the merger, and that, overall, these risks were significantly outweighed by the potential benefits of the merger.

         Although this discussion of the information and factors considered by the Caremark board of directors is believed to include the material factors considered by the Caremark board of directors, it is not intended to be exhaustive and may not include all of the factors considered by the Caremark board of directors. In reaching its determination to approve and recommend the merger and the merger agreement, the Caremark board of directors did not quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination that the merger and the merger agreement are advisable and in the best interests of Caremark and its stockholders. Rather, the Caremark board of directors based its position and recommendation on the totality of the information presented to and factors considered by it. In addition, individual members of the Caremark board of directors may have given differing weights to different factors.

         In considering the recommendation of the Caremark board of directors with respect to the merger and the merger agreement, you should be aware that certain Caremark directors and officers have arrangements that cause them to have interests in the transaction that are different from, or are in addition to, the interests of Caremark stockholders generally. See “Interests of Caremark Executive Officers and Directors in the Merger” beginning on page 86.

    Recommendations of the Caremark Board of Directors

         The Caremark board of directors has unanimously determined that the merger agreement and the transactions contemplated by it, including the merger, are advisable and in the best interests of Caremark and the Caremark stockholders and unanimously recommends that the Caremark stockholders vote “FOR” the proposal to adopt the merger agreement and approve the merger and “FOR” the adjournment or postponement of the Caremark special meeting, including if necessary, to solicit additional proxies in favor of such adoption and approval.

    Caremark Projections

         In connection with the review of the merger, certain financial projections prepared by management of Caremark concerning Caremark on a stand-alone, pre-merger basis, were exchanged with CVS.

         The projections are “forward-looking statements” and Caremark’s actual results may differ materially from those set forth in the projections. See “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 38 for a discussion of the risks you should consider in reviewing the projections set forth in this joint proxy statement/ prospectus.

    The material portions of the financial projections prepared by management of Caremark can be summarized as follows:

    Caremark

          2006E     2007E




    Net Revenue (in millions)   $ 36,819   $ 38,735
    Earnings Per Share   $ 2.43   $ 2.91

         These projections were not prepared with a view to public disclosure or compliance with published guidelines established by the SEC or the American Institute of Certified Public Accountants regarding projections. None of CVS, Caremark or their respective affiliates or CVS’ or Caremark’s independent registered public accounting firm assumes any responsibility if future results differ from these projections. The projections are subjective in many respects and thus susceptible to interpretation and periodic revision based on actual experience and recent developments. While presented with numeric specificity, the projections reflect numerous assumptions made by the management of Caremark with respect to industry performance and competition, general business, economic, market and financial conditions and other matters, all of which are difficult to predict and many of which are beyond the control of Caremark. For these reasons, the inclusion of the projections in this document should not be regarded as an indication that CVS, Caremark, any recipient of the projections or their respective affiliates or representatives considered or consider the projections to be necessarily predictive of actual future events, and the projections should not be relied upon as such. Actual results may be higher or lower than those estimated. CVS and Caremark do not generally publish their respective business plans and strategies or make external disclosures of their respective anticipated financial position or results of operations. Accordingly, CVS and Caremark do not intend to, and specifically decline any obligation to, update or otherwise revise the prospective financial information to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even if any or all the underlying assumptions are shown to be in error. Also, CVS and Caremark do not intend to, and specifically decline any obligation to, update or revise the prospective financial information to reflect changes in general economic or industry conditions. Neither CVS’ auditors nor Caremark’s auditors, nor any other independent registered public accounting firm, have compiled, examined or performed any procedures with respect to these projections, nor have they expressed any opinion or any other form of assurance on this information or its

    79






    achievability, and assume no responsibility for, and disclaim any association with, this prospective financial information.

    Opinions of Financial Advisors to Caremark

         Caremark has retained UBS and JPMorgan as its financial advisors in connection with the merger.

         On November 1, 2006, at a meeting of the Caremark board of directors held to evaluate the proposed merger, UBS and JPMorgan delivered to the Caremark board of directors separate oral opinions, which opinions were confirmed by delivery of separate written opinions dated November 1, 2006, to the effect that, as of that date and based on and subject to various assumptions, matters considered and limitations described in such opinions, the exchange ratio provided for in the merger was fair, from a financial point of view, to holders of Caremark common stock.

         UBS’ and JPMorgan’s opinions, the full texts of which describe the assumptions made, procedures followed, matters considered and limitations on the review undertaken by UBS and JPMorgan, are attached as Annex F and Annex G, respectively, and are incorporated into this document by reference. UBS’ and JPMorgan’s opinions were directed only to the fairness, from a financial point of view, of the exchange ratio provided for in the merger and do not address any other aspect of the merger. The opinions do not address the relative merits of the merger as compared to other business strategies or transactions that might be available with respect to Caremark or Caremark’s underlying business decision to effect the merger. The opinions do not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the merger. Holders of Caremark common stock are encouraged to read the opinions carefully in their entirety. The summaries of UBS’ and JPMorgan’s opinions described below are qualified in their entirety by reference to the full texts of the opinions.

       Opinion of UBS Securities LLC

         In arriving at its opinion, UBS:

    • reviewed publicly available business and financial information relating to Caremark and CVS;


    • reviewed internal financial information and other data relating to Caremark’s business and financial prospects that were provided to or reviewed with UBS by Caremark’s management and not publicly available, including financial forecasts and estimates for calendar years 2006 and 2007 prepared by Caremark’s management and financial forecasts and estimates for calendar years 2008 through 2011, extrapolated per assumptions and other guidance provided to UBS by Caremark’s management;


    • reviewed internal financial information and other data relating to CVS’ business and financial prospects that were provided to or reviewed with UBS by CVS’ management and not publicly available, including financial forecasts and estimates for calendar years 2006 and 2007 prepared by CVS’ management and financial forecasts and estimates for calendar years 2008 through 2011, extrapolated per assumptions and other guidance provided to UBS by CVS’ management;


    • reviewed estimates of synergies prepared by a third party consultant to Caremark and CVS that were provided to UBS by Caremark and not publicly available;


    • considered certain pro forma effects of the merger on CVS’ financial statements for calendar years 2007 and 2008 and certain pro forma effects of the merger relative to Caremark’s projected earnings per share for calendar years 2007 and 2008 on a stand-alone basis;


    • conducted discussions with members of the senior managements of Caremark and CVS concerning the businesses and financial prospects of Caremark and CVS;


    • reviewed publicly available financial and stock market data with respect to other companies UBS believed to be generally relevant;

    80






    • reviewed the publicly available financial terms of other transactions in the retail pharmacy and pharmacy benefits management industries;


    • reviewed current and historical market prices of Caremark common stock and CVS common stock;


    • reviewed the merger agreement; and


    • conducted other financial studies, analyses and investigations, and considered other information, as UBS deemed necessary or appropriate.

         In connection with its review, with Caremark’s consent, UBS did not assume any responsibility for independent verification of any of the information provided to or reviewed by UBS for the purpose of its opinion and, with Caremark’s consent, relied on that information being complete and accurate in all material respects. In addition, at Caremark’s direction, UBS did not make any independent evaluation or appraisal of any of the assets or liabilities, contingent or otherwise, of Caremark or CVS and UBS was not furnished with any such evaluation or appraisal. With respect to the financial forecasts and estimates for calendar years 2006 and 2007, pro forma effects for calendar year 2007 and synergies referred to above, UBS assumed, at Caremark’s direction, that they were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of Caremark and CVS as to the future performance of Caremark and CVS for the covered periods and such pro forma effects and synergies. UBS was not provided with, and did not have access to, financial forecasts and estimates prepared by the managements of Caremark and CVS beyond calendar year 2007. With respect to the financial forecasts and estimates for calendar years 2008 through 2011 and pro forma effects for calendar year 2008 referred to above, UBS relied, at Caremark’s direction, on the assessments of the managements of Caremark and CVS that such financial forecasts and estimates were a reasonable basis on which to evaluate both the future performance of Caremark and CVS for the covered periods and such pro forma effects, and were appropriate for UBS to utilize in its analyses. In addition, UBS assumed, with Caremark’s approval, that the financial forecasts and estimates, including synergies, referred to above would be achieved at the times and in the amounts projected. UBS also assumed, with Caremark’s consent, that the merger would qualify for federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. UBS’s opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information available to UBS as of, the date of its opinion. Although subsequent developments may affect its opinion, UBS does not have any obligation to update, revise or reaffirm its opinion.

         UBS was not authorized to, and did not, solicit indications of interest in a business combination with Caremark from any party. At Caremark’s direction, UBS was not asked to, and it did not, offer any opinion as to the terms of the merger agreement, other than the exchange ratio to the extent expressly specified in its opinion, or the form of the merger. UBS expressed no opinion as to what the value of CVS common stock would be when issued pursuant to the merger or the price at which CVS common stock or Caremark common stock would trade at any time. In rendering its opinion, UBS assumed, with Caremark’s consent, that Caremark, CVS and Twain MergerSub Corp. would comply with all material terms of the merger agreement and that the merger would be consummated in accordance with the terms of the merger agreement without any adverse waiver or amendment of any material term or condition of the merger agreement. UBS also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger would be obtained without any material adverse effect on Caremark, CVS or the merger. Except as described above, Caremark imposed no other instructions or limitations on UBS with respect to the investigations made or the procedures followed by UBS in rendering its opinion.

       Opinion of J.P. Morgan Securities Inc.

         In connection with rendering its opinion, JPMorgan, among other things:

    • reviewed a draft of the merger agreement dated October 31, 2006;


    • reviewed certain publicly available business and financial information concerning Caremark and CVS and the industries in which they operate;

    81






    • compared the financial and operating performance of Caremark and CVS with publicly available information concerning certain other companies it deemed relevant and reviewed the current and historical market prices of Caremark common stock and CVS common stock and certain publicly traded securities of such other companies;


    • reviewed certain internal financial analyses and forecasts prepared or approved by the managements of Caremark and CVS relating to their respective businesses, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the merger; and


    • performed such other financial studies and analyses and considered such other information as it deemed appropriate for the purposes of its opinion.

         In addition, JPMorgan held discussions with certain members of the management of Caremark and CVS with respect to certain aspects of the merger, the past and current business operations of Caremark and CVS, the financial condition and future prospects and operations of Caremark and CVS, the effects of the merger on the financial condition and future prospects of Caremark and CVS and certain other matters it believed necessary or appropriate to its inquiry.

         In giving its opinion, JPMorgan relied upon and assumed, without assuming responsibility or liability for independent verification, the accuracy and completeness of all information that was publicly available or was furnished to or discussed with it by Caremark and CVS or otherwise reviewed by or for it. JPMorgan did not conduct, nor was it provided with, any valuation or appraisal of any assets or liabilities, nor did it evaluate the solvency of Caremark or CVS under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on the financial analyses and forecasts referred to above, including the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the merger, JPMorgan assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments of management as to the expected future results of operations and financial condition of Caremark and CVS to which such analyses or forecasts relate. JPMorgan expressed no view as to such analyses or forecasts, including the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the merger, or the assumptions on which they were based. JPMorgan also assumed that the merger will qualify as a tax-free reorganization for U.S. federal income tax purposes, and that, in all respects material to its analyses, the other transactions contemplated by the merger agreement will be consummated as described in the merger agreement, and that the definitive merger agreement would not differ in any material respects from the draft of the merger agreement furnished to it. JPMorgan is not a legal, tax or regulatory advisor and relied upon, without independent verification, the assessment of Caremark and its legal, tax or regulatory advisors with respect to legal, tax or regulatory matters. JPMorgan further assumed, in all respects material to its analyses, that all of the representations and warranties of each party contained in the merger agreement are true and correct, that each party to the merger agreement will perform all of the covenants and agreements required to be performed by it thereunder without any consents or waivers of the other parties thereto, and that all material governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on Caremark or CVS or on the contemplated benefits of the merger.

         The JPMorgan opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to it as of, the date of its opinion. Subsequent developments may affect JPMorgan’s opinion and JPMorgan does not have an obligation to update, revise, or reaffirm its opinion. JPMorgan’s opinion is limited to the fairness, from a financial point of view, to the holders of Caremark common stock of the exchange ratio in the merger and it expresses no opinion as to the fairness of the merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of Caremark or as to the underlying decision by Caremark to engage in the merger. JPMorgan expressed no opinion as to the price at which Caremark common stock or CVS common stock will trade at any future time.

       Summary of Joint Financial Analyses of Caremark’s Financial Advisors

         In connection with rendering their respective opinions to Caremark’s board of directors, UBS and JPMorgan jointly performed a variety of financial and comparative analyses which are summarized below. The following

    82






    summary is not a complete description of all analyses performed and factors considered by UBS and JPMorgan in connection with their opinions. The preparation of a financial opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. With respect to the selected companies analysis summarized below, no company used as a comparison is identical or directly comparable to Caremark or CVS. A selected companies analysis necessarily involves complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the public trading values of the companies concerned.

         UBS and JPMorgan believe that the analyses and the summary below must be considered as a whole and that selecting portions of the analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying UBS’s and JPMorgan’s analyses and their respective opinions. None of the analyses performed by UBS and JPMorgan was assigned greater significance or reliance by UBS or JPMorgan than any other. Each of UBS and JPMorgan arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole. Neither UBS nor JPMorgan drew, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion.

         The estimates of the future performance of Caremark and CVS provided by or reviewed with the respective managements of Caremark and CVS in or underlying UBS’s and JPMorgan’s analyses are not necessarily indicative of future results or values, which may be significantly more or less favorable than those estimates. In performing their analyses, UBS and JPMorgan considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of Caremark and CVS. Estimates of the financial value of companies do not necessarily purport to be appraisals or reflect the prices at which companies actually may be sold.

         The exchange ratio was determined through negotiation between Caremark and CVS and the decision to enter into the merger was solely that of Caremark’s board of directors. UBS’s and JPMorgan’s opinions and financial analyses were only one of many factors considered by Caremark’s board of directors in its evaluation of the merger and should not be viewed as determinative of the views of Caremark’s board of directors or management with respect to the merger or the exchange ratio provided for in the merger.

         The following is a brief summary of the material financial analyses reflected in UBS’s and JPMorgan’s joint financial presentation reviewed with Caremark’s board of directors in connection with their respective opinions relating to the proposed merger. The financial analyses summarized below include information presented in tabular format. In order to fully understand UBS’s and JPMorgan’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of UBS’s and JPMorgan’s financial analyses.

         Historical Exchange Ratio Analysis

         UBS and JPMorgan reviewed the ratio of Caremark’s daily closing stock prices to CVS’ daily closing stock prices for the 52-week period ended October 31, 2006 and the ratio of the average daily closing stock prices of Caremark to the average daily closing stock prices of CVS for the three-month and six-month periods ended October 31, 2006. This analysis indicated the following high and low implied exchange ratios for the 52-week period ended October 31, 2006 and average implied exchange ratios for the three-month and six month periods ended October 31, 2006, as compared to the exchange ratio provided for in the merger:

        Implied Exchange Ratio

    52-Week High   2.127x
    52-Week Low   1.463x
    Three-Month Average   1.673x
    Six-Month Average   1.651x
    Merger Exchange Ratio   1.670x

    83






         Selected Companies Analysis

         UBS and JPMorgan performed separate selected companies analyses of Caremark and CVS by reviewing selected financial data of Caremark, CVS and selected publicly held companies in businesses similar to those of Caremark and CVS. Estimated financial data of the selected companies were based on publicly available research analysts’ estimates. Estimated financial data of Caremark and CVS were based on internal estimates of the respective managements of Caremark and CVS.

         Caremark. UBS and JPMorgan reviewed, among other things, closing stock prices on October 31, 2006 of Caremark and the following selected pharmaceutical benefit management companies, which are referred to as the Caremark selected companies, as a multiple of calendar year 2007 estimated earnings per share, which is referred to as EPS, and enterprise values, calculated as fully diluted equity value based on closing stock prices on October 31, 2006, plus the book value of debt and minority interests, less cash and cash equivalents, of Caremark and the Caremark selected companies as a multiple of calendar year 2007 estimated earnings before interest, taxes, depreciation and amortization, which is referred to as EBITDA:

    • Express Scripts, Inc.


    • Medco Health Solutions, Inc.

         CVS. UBS and JPMorgan reviewed, among other things, closing stock prices on October 31, 2006 of CVS and the following selected retail pharmacy companies, which are referred to as the CVS selected companies, as a multiple of calendar year 2007 estimated EPS and enterprise values of CVS and the CVS selected companies as a multiple of calendar year 2007 estimated EBITDA:

    • Longs Drug Stores Corporation


    • Rite Aid Corporation


    • Walgreen Co.

         UBS and JPMorgan then applied calendar year 2007 estimated EPS and EBITDA multiples of 16.9x and 10.5x, respectively, derived from Caremark and the Caremark selected companies to corresponding financial data of Caremark and calendar year 2007 estimated EPS and EBITDA multiples of 16.6x and 7.5x, respectively, derived from CVS and the CVS selected companies to corresponding financial data of CVS. This analysis indicated the following implied exchange ratio reference range as compared to the exchange ratio provided for in the merger:

    Implied Exchange    
    Ratio Reference Range   Merger Exchange Ratio


    1.184x - 2.087x   1.670x

         Contribution Analysis

         UBS and JPMorgan reviewed the relative contributions of Caremark and CVS to the combined company’s EBITDA, earnings before interest and taxes, which is referred to as EBIT, and net income for the calendar years 2006 and 2007, enterprise value and equity value based on closing stock prices on October 31, 2006 and book equity value as of June 30, 2006. The implied relative contributions of Caremark and CVS to the combined company based on EBITDA, EBIT and enterprise value contributions were adjusted for the relative contributions of Caremark and CVS to the combined company’s estimated net debt as of June 30, 2006, calculated as outstanding debt less cash and cash equivalents. Estimated financial data of Caremark and CVS were based on internal estimates of the respective managements of Caremark and CVS and reflected, in the case of CVS’ calendar year 2006 estimated EBITDA, EBIT and net income, the full-year pro forma impact of CVS’ acquisition of the stand-alone drugstores of Osco/Sav-on. Based on the implied equity ownership percentages of Caremark’s stockholders in the combined company derived from the relative contributions of Caremark and CVS for each metric reviewed, this analysis

    84






    indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

    Implied Exchange    
    Ratio Reference Range   Merger Exchange Ratio


    1.443x - 1.768x   1.670x

         Discounted Cash Flow Analysis

         UBS and JPMorgan reviewed the stand-alone unlevered, after-tax free cash flows, which are referred to as projected free cash flows, that Caremark and CVS could each generate over calendar years 2007 through 2011, five years being a commonly used and widely accepted period for evaluating future cash flows in a discounted cash flow analysis. Estimated financial data of Caremark and CVS were based on internal estimates for calendar year 2007 prepared by the respective managements of Caremark and CVS and estimates for calendar years 2008 through 2011 extrapolated per assumptions and other guidance provided to UBS and JPMorgan by the respective managements of Caremark and CVS.

     

    Caremark. UBS and JPMorgan calculated the estimated present value of the projected free cash flows that Caremark could generate over calendar years 2007 through 2011. UBS and JPMorgan also calculated a range of terminal values by applying EBITDA terminal value multiples of 9.0x to 11.0x to Caremark’s calendar year 2011 estimated EBITDA. The cash flows and terminal values were then discounted to present value using discount rates ranging from 10.0% to 11.0%.

    CVS. UBS and JPMorgan calculated the estimated present value of the projected free cash flows that CVS could generate over calendar years 2007 through 2011. UBS and JPMorgan also calculated a range of terminal values by applying EBITDA terminal value multiples of 8.5x to 10.5x to CVS’ calendar year 2011 estimated EBITDA. The cash flows and terminal values were then discounted to present value using discount rates ranging from 8.5% to 9.5%.

         Based on the resulting implied equity reference ranges for Caremark and CVS of $53.15 to $63.66 and $32.54 to $42.08, respectively, this analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

    Implied Exchange    
    Ratio Reference Range   Merger Exchange Ratio


    1.263x - 1.957x   1.670x

         Accretion/Dilution Analysis

         UBS and JPMorgan reviewed the potential pro forma effect of the merger on CVS’ calendar years 2007 and 2008 estimated EPS and also analyzed the potential pro forma effect of the merger relative to Caremark’s calendar years 2007 and 2008 estimated EPS on a stand-alone basis, in each case after giving effect to potential synergies anticipated by the managements of Caremark and CVS to result from the merger based on estimates calculated by a third-party consultant to Caremark and CVS. Estimated financial data of Caremark and CVS were based on internal estimates for calendar year 2007 prepared by the respective managements of Caremark and CVS and estimates for calendar year 2008 extrapolated per assumptions and other guidance provided to UBS and JPMorgan by the respective managements of Caremark and CVS. Based on the exchange ratio provided for in the merger, the closing stock price of CVS common stock on October 31, 2006 and an assumed merger closing date of December 31, 2006, this analysis indicated that the merger could be accretive to CVS’ calendar year 2008 estimated EPS and Caremark’s calendar years 2007 and 2008 estimated EPS and dilutive to CVS’ calendar year 2007 estimated EPS. Actual results may vary from projected results and the variations may be material.

    85






          Miscellaneous

         Under the terms of separate letter agreements, Caremark has agreed to pay UBS and JPMorgan customary fees for their financial advisory services in connection with the merger, portions of which were payable in connection with their opinions and significant portions of which are contingent upon the completion of the merger. In addition, Caremark has agreed to reimburse UBS and JPMorgan for their reasonable expenses, including reasonable fees, disbursements and other charges of legal counsel, and to indemnify each of UBS and JPMorgan and related parties against liabilities, including liabilities under federal securities laws, relating to, or arising out of, its engagement.

         In the past, UBS has provided investment banking services to Caremark unrelated to the proposed merger, for which UBS received compensation, including having acted as co-documentation agent for Caremark’s existing bank credit facility in 2006, as agent for an interest-rate hedging transaction undertaken by Caremark in 2005 and providing certain investment banking services with respect to Caremark’s stock repurchase program in 2005 and 2006. In 2004, UBS also acted as a financial advisor to Caremark in connection with its acquisition of AdvancePCS and provided other services in connection with the financing for such acquisition and the related debt tender offer for outstanding AdvancePCS senior notes. In addition, an affiliate of UBS currently is a lender under Caremark’s existing bank credit facility, for which such affiliate has received and expects to receive compensation. In the ordinary course of business, UBS, its successors and affiliates may hold or trade, for their own accounts and the accounts of their customers, securities of Caremark and CVS and, accordingly, may at any time hold a long or short position in such securities.

         JPMorgan and its affiliates have provided in the past, and may provide in the future, investment banking, commercial banking and other financial services to Caremark and CVS. Such services for Caremark have included acting as co-documentation agent with respect to Caremark’s credit facilities in 2004, acting as co-documentation agent with respect to Caremark’s credit facilities in 2006 and advising Caremark in connection with Caremark’s acquisition of AdvancePCS in March 2004. Such services for CVS have included acting as co-manager in the placement of certain debt securities of CVS in 2006. In addition, JPMorgan’s commercial bank affiliates are lenders to each of Caremark and CVS under their respective credit facilities. In the ordinary course of their businesses, JPMorgan and its affiliates may actively trade the debt and equity securities of Caremark or CVS for its own account or for the accounts of customers and, accordingly, JPMorgan may at any time hold long or short positions in such securities.

         Caremark selected UBS and JPMorgan as its financial advisors in connection with the merger because they are internationally recognized investment banking firms with substantial experience in similar transactions and because of their familiarity with Caremark and its business. UBS and JPMorgan are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities and private placements.

    Interests of Caremark Executive Officers and Directors in the Merger

         In considering the recommendation of the Caremark board of directors with respect to the merger, Caremark stockholders should be aware that executive officers of Caremark and members of the Caremark board of directors may have interests in the transactions contemplated by the merger agreement that are different than, or in addition to, the interests of the Caremark stockholders generally. The Caremark board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and making its recommendation. These interests are summarized below.

          Board and Committee Composition of the Combined Company

         The following summarizes certain changes that will take effect at the effective time of the merger. Certain members of the Caremark board of directors will continue as directors of the combined company. At the effective time, the board of directors of the combined company will be comprised of an equal number of individuals who, before the completion of the merger, were members of the Caremark board of directors and individuals who, before the completion of the merger, were members of the CVS board of directors. Mr. Crawford, currently the chairman,

    86






    chief executive officer and president of Caremark, will serve as chairman of the board of directors of the combined company.

         At the effective time, the executive committee of the board of directors of the combined company will also be comprised of an equal number of individuals who, before the completion of the merger, were members of the Caremark board of directors and individuals who, before the completion of the merger, were members of the CVS board of directors. As of the effective time, the executive committee of the CVS/Caremark board of directors will consist of Thomas M. Ryan, E. Mac Crawford, one individual who, before completion of the merger, was a member of the CVS board of directors and one individual who, before completion of the merger, was a member of the Caremark board of directors.

         In addition, at the effective time, the chairman of the audit committee of the board of directors of the combined company will be designated from among the individuals who, before the completion of the merger, were members of the Caremark board of directors.

          Equity-Based Awards

         All of the options held by executive officers and directors of Caremark under the equity compensation plans maintained by Caremark (with the exception of any options outstanding under legacy plans of AdvancePCS) will vest and become fully exercisable in connection with the merger. Based upon options outstanding as of January 15, 2007, the number of unvested options to acquire shares of Caremark common stock held by E. Mac Crawford, Edward L. Hardin, Jr., Howard A. McLure, Rudy Mladenovic and William R. Spalding, Caremark’s named executive officers, that will become fully vested and exercisable as a result of the merger is 3,021,200 in the aggregate. The number of unvested options to acquire shares of Caremark common stock held by the executive officers (other than Caremark’s named executive officers) that will become fully vested and exercisable as a result of the merger is 1,768,000 in the aggregate. However, of these options, 757,800 options held by Caremark’s executive officers and directors vest in any event in the ordinary course consistent with the terms and conditions of these options on March 1, 2007, and another 367,000 of these options vest in the ordinary course consistent with the terms and conditions of these options on May 10, 2007.

         In connection with the merger, each Caremark option that is outstanding immediately before completion of the merger will remain outstanding following the completion of the merger and will be converted into the right to acquire shares of CVS common stock as described in the section entitled “The Merger Agreement—Caremark Stock Options” beginning on page 107. Any option so converted shall as a general rule be exercisable for the remainder of such option’s original term as granted by Caremark except for options granted before September 21, 1998, options granted under the plan adopted in 2004 and options outstanding under legacy plans of AdvancePCS, which options will expire in accordance with the original grant terms. Based on the number of Caremark options outstanding as of January 15, 2007, a total of 11,093,327 Caremark options held by Caremark executive officers and directors will be so converted upon completion of the merger.

         For additional information about the directors and the executive officers of Caremark and a summary of the Caremark common stock beneficially owned by such individuals, see the sections entitled “About the Meeting—Item 1: Election of Directors,” “General Information About the Company—Directors Continuing in Office,” “General Information About the Company—Executive Officers” and “General Information About the Company—Stock Ownership of Directors and Executive Officers” in the definitive proxy statement for Caremark’s 2006 Annual Meeting of Stockholders filed with the SEC on April 7, 2006.

          Employment Arrangements

         Caremark has entered into employment agreements with each of its executive officers. Under Caremark’s employment agreement with E. Mac Crawford, Mr. Crawford has the right to resign for any reason within 90 days after a change in control and, upon such resignation, Mr. Crawford is entitled to receive (1) an aggregate severance payment equal to the sum of (A) his base salary for the remaining term of his employment agreement and (B) a separation payment equal to at least two times his base salary (the separation payment being the cash equivalent of Mr. Crawford’s annual bonus target) multiplied by the number of years (including fractions of years) remaining in

    87






    the term of his employment agreement, and (2) continuation of welfare benefits (e.g., health, dental, disability and life insurance) for the remaining term of his employment agreement. As of January 15, 2007, the term of Mr. Crawford’s employment agreement expires September 1, 2014, and the term will be automatically extended for an additional year on March 18, 2007 unless the Company gives notice of non-extension at least 30 days prior to such date. If Mr. Crawford’s employment is terminated by Caremark other than for “cause” or if he terminates his employment for “good reason” (each as defined in the employment agreement), then Mr. Crawford is entitled to receive the same termination payments and benefits described above. Mr. Crawford intends to resign his employment on completion of the merger and thereafter will serve as chairman of the board of directors of the combined company. Upon his resignation, Mr. Crawford is entitled to a cash severance payment as described in clause (1) in an amount ranging from $36,000,000 to $40,800,000 depending on the remaining term of his employment agreement when completion of the merger occurs. Mr. Crawford, however, as an indication of his commitment to the merger and his confidence in the long-term economic benefits to be derived from the merger, has agreed to accept cash severance payments in the reduced amount of $26,400,000 regardless of the date the merger is completed. See the table entitled “Payment and Benefits Resulting from the Change in Control for Caremark’s Named Executive Officers” below.

         Under Caremark’s employment agreement with Edward L. Hardin, Mr. Hardin has the right to resign at any time within 180 days following a change in control and receive severance benefits. Upon any such resignation, Mr. Hardin is entitled to receive (1) a specified amount consisting of his base salary for the remainder of the term of his employment agreement and any portion or portions of any bonus or other cash incentive compensation accrued with respect to him on Caremark’s books through the date of termination, and (2) continuation of welfare benefits for the remainder of the term of his employment agreement. The term of Mr. Hardin’s employment extends through June 16, 2008. Mr. Hardin intends to retire and resign his employment on completion of the merger and thereafter will serve as a litigation consultant to the combined company. Caremark and Mr. Hardin are negotiating the terms of his consulting agreement. See the table entitled “Payments and Benefits Resulting from the Change in Control for Caremark’s Named Executive Officers” below.

         Under the employment agreement with Diane Nobles, Ms. Nobles has the right to resign at any time after a change in control and receive severance benefits. If Ms. Nobles resigns or the combined company terminates Ms. Nobles’ employment other than for cause (as defined in her employment agreement) after completion of the merger, Ms. Nobles is entitled to receive (1) an aggregate severance payment equal to the sum of Ms. Nobles’ base salary and target bonus, (2) continuation of welfare benefits for a period of one year, and (3) up to $10,000 in outplacement services.

         Under the respective employment agreements of Messrs. Mark Weeks and Dennis Zeleny, if, within six months following a change in control of Caremark the combined company fails to assume upon request all of Caremark’s obligations under such executive officer’s employment agreement, or if following a change in control of Caremark, the combined company terminates the executive officer’s employment, the executive officer is entitled to receive (1) an aggregate severance payment equal to two times the sum of the executive officer’s base salary and annual incentive bonus and (2) continuation of welfare benefits for a period of two years (provided that, instead of continuation of welfare benefits, Mr. Weeks is entitled to a one year COBRA continuation of coverage at active employee rates).

         Under their employment agreements, certain Caremark executives are entitled to receive a tax gross-up payment if any of the total payments made to them would be subject to the excise tax under Section 4999 of the Internal Revenue Code. However, based on preliminary calculations it is not expected that these executives will be subject to excise taxes. Finally, all the employment agreements are subject to amendments to minimize the risk that an executive’s benefits will be subject to an additional tax under Section 409A of the Code.

      (1) More detail relating to the number and exercise price of the options that will vest and become exercisable as a result of the merger for each individual named in the chart above is as follows (assuming that the merger had been closed on December 31, 2006 and not adjusting the exercise price to reflect the payment of the Caremark special cash dividend, with respect to which the maximum reduction to the exercise price would be $2.00):
         
      E. Mac Crawford: 360,000 options with an exercise price of $32.03, 600,000 options with an exercise price of $37.92 and 450,000 options with an exercise price of $50.84.
      Edward L. Hardin, Jr.: 60,000 options with an exercise price of $32.03 and 80,000 options with an exercise price of $37.92.
      Howard A. McLure: 120,000 options with an exercise price of $32.03, 160,000 options with an exercise price of $37.92, 111,200 options with an exercise price of $43.55 and 125,000 options with an exercise price of $50.84.
      Rudy Mladenovic: 120,000 options with an exercise price of $32.03, 160,000 options with an exercise price of $37.92 and 150,000 options with an exercise price of $50.84.
      William R. Spalding: 400,000 options with an exercise price of $44.13 and 125,000 options with an exercise price of $50.84.
         
      (2) For purposes of this chart, values are calculated by subtracting the exercise price of the stock option from the fair market value of the underlying common stock. For purposes of this table, fair market value is deemed to be $56.83, the closing price of Caremark common stock on January 12, 2007 (not adjusting the exercise price to reflect the Caremark special cash dividend, with respect to which the maximum reduction to the exercise price would be $2.00).

    89






     

     

    (3) Includes estimated payments of base salary and bonus due upon termination of employment upon the occurrence of a change in control, based on salary and bonus information as of January 12, 2007.

    (4) Under the terms of Mr. Crawford’s employment agreement, he is entitled to a cash severance payment in an amount ranging from $36,000,000 to $40,800,000, depending on the remaining term of his employment agreement at the time the closing of the merger occurs. Mr. Crawford, however, as an indication of his commitment to the transaction and his confidence in the long-term economic benefits to be derived from the merger, has agreed to accept cash severance payments in the reduced amount of $26,400,000 regardless of the date of closing of the merger.

    (5) Mr. Hardin’s amount of cash severance payment is calculated based on an assumed closing date of December 31, 2006, and his actual cash severance payment will depend on the remaining term of his employment agreement at the time the closing of the merger occurs.

    (6) Other payments and benefits set forth in the chart above are calculated based on an assumed closing date of December 31, 2006.

    (7) Other payments and benefits includes the following for Mr. Crawford: $67,467 cash payment in lieu of 401(k) match; $804,640 insurance premium payment for policy to fund Caremark’s obligation under the Survivor Benefit Agreement; $3,666,256 cash value of policy to be transferred to Mr. Crawford pursuant to the terms of the Survivor Benefit Agreement; $138,816 for term life insurance coverage, $9,031 paid for long term disability coverage; and $2,931,000 representing the present value of Mr. Crawford’s incremental retirement benefits under his Supplemental Executive Retirement Plan because he will no longer be subject to a benefit reduction upon early retirement. In addition to the amount set forth above, Mr. Crawford will be entitled to receive continued health and welfare benefits, accrued paid-time-off, which is referred to as PTO, and payment of existing deferred compensation accounts under Caremark’s executive benefit plan.

    (8) Other payments and benefits includes $8,679 paid for long term disability coverage. In addition to the amount set forth above, Mr. Hardin will be entitled to receive continued health and welfare benefits, accrued PTO and payment of existing deferred compensation accounts under Caremark’s executive benefit plan.

    (9) Includes the estimated amount to be credited to the executive’s deferral account described in “—Employment Arrangements with the Combined Company” beginning on page 90. The amount is calculated based on the payments and benefits the executive would have been paid under his existing Caremark employment agreement if the executive had been terminated without cause following the change in control, including, to the extent applicable, base pay, bonus, accrued PTO, cash payment in lieu of 401(k) match, life insurance premiums, financial planning allowance, physical exam allowance, car allowance, cellular phone reimbursement, country club dues and long term disability coverage. In addition, the value of certain health and welfare benefits will be included in the executive’s deferral account.

    (10) Amount does not include the separate restricted stock grant to be provided to Mr. McLure upon closing of the Merger. See “—Employment Arrangements with the Combined Company” beginning on page 90.

          Employment Arrangements with the Combined Company

         Certain other executives of Caremark have employment agreements with Caremark, but have agreed to take positions with the combined company after the completion of the merger. These executives include: Jack Bruner, Peter J. Clemens, Sara J. Finley, David Golding, David Joyner, Bradley S. Karro, James Luthin, Howard A. McLure, Rudy Mladenovic and William Spalding. These executives have entered into term sheets with CVS (on behalf of the combined company), which will supersede their Caremark agreements upon completion of the merger and establish the basic terms and conditions of each executive’s employment thereafter. Andrew Crawford, Mr. Crawford’s son, has also entered into a substantially similar term sheet. The main provisions of the term sheets are summarized below.

    90






         Each term sheet provides the executive will receive benefits and perquisites comparable to those currently provided by CVS to similarly situated senior executives and provides the executive with a base salary and target bonus not less than his or her respective current base salary and target bonus with Caremark. The term sheet also contains certain restrictive covenants applicable to the executive, including noncompetition, nonsolicitation and confidentiality restrictions.

         Pursuant to these term sheets, upon the effective time of the merger, the combined company will establish a deferral account for the executive to be credited with the amount of all severance benefits which the executive would have been paid under his or her existing Caremark employment agreement if such executive had been terminated without “cause” (as defined in the executive’s Caremark employment agreement) following the change in control. Each deferral account will be comprised of cash or a combination of cash and up to 50% in restricted stock units based on the value of the combined company’s common stock on the date of the completion of the merger. During the applicable deferral period, CVS will credit interest earned on any cash portion of the deferral account based on the treasury interest rate and will credit dividend equivalents on any restricted stock unit portion of the deferral account when dividends are paid on the combined company’s common stock. Any restricted stock units in the deferral account will be settled in properly registered shares of the combined company’s common stock.

         The deferral account of Ms. Finley and Mr. McLure will be fully vested and will be distributed in a lump sum as soon as practicable after the third anniversary of the completion of the merger or such later date selected by the executive, but it will be distributed earlier upon the executive’s death or any termination of employment.

         The deferral accounts of the other executives will vest 50% as of the second anniversary of the completion of the merger and 50% as of the third anniversary of the completion of the merger. These deferral accounts are subject to earlier vesting in full upon the occurrence of one of the following “vested termination events”: (1) the executive’s death or disability, (2) termination of the executive by the combined company without “cause” (as defined in the term sheet), (3) resignation by the executive for “good reason” (as defined in the term sheet), or (4) ”termination without cause” (as defined in the term sheet) within two years following a change in control of the combined company. The deferral account will be distributed in a lump sum as soon as practicable after the occurrence of the earlier of a “vested termination event” or the third anniversary of the completion of the merger or such later date selected by the executive.

         The estimated amount of the deferral accounts for each named executive officer is set forth in “—Payment and Benefits Resulting from the Change in Control for Caremark’s Named Executive Officers” above, and the estimated aggregate amount of the deferral accounts for Mr. Bruner, Mr. Clemens, Ms. Finley, Mr. Golding, Mr. Joyner, Mr. Karro and Mr. Luthin is $10,346,159.

         Each of Ms. Finley and Mr. McLure will also receive a restricted stock unit award based on the value of CVS common stock as of the effective time of the merger. The award will vest and be settled on the third anniversary of the grant date unless a further deferral election is made, but vesting and settlement will be accelerated upon termination of the executive’s employment by the combined company without “cause,” (as defined in the term sheet) by the executive for “good reason” (as defined in the term sheet) or upon the executive’s death or disability. Dividend equivalents on the award will be paid to the executive in cash during the vesting period and when dividends are paid on the combined company’s common stock. The award will be settled in properly registered shares of the combined company’s common stock. The award will be forfeited if the executive’s employment is terminated for “cause” or by the executive without “good reason”. The amount of the restricted stock unit award will be $750,000 for Ms. Finley and $1,500,000 for Mr. McLure.

         If the executive’s employment terminates before a change in control of the combined company as a result of death or disability, or if the combined company terminates the executive officer’s employment without “cause” or the executive resigns for “good reason” the combined company will pay to the executive:

    • such executive’s salary and bonus which have been earned but not yet paid;

    • pro rata portion of such executive’s target bonus for the year of termination;

    91






    • settlement of 100% of the executive’s vested deferral account balance in accordance with the applicable deferral terms; and

    • full vesting and settlement of such executive’s restricted stock unit award if applicable.

         If before a change in control of the combined company, the executive’s employment is terminated by the combined company for “cause” or by the executive without “good reason”, the combined company will pay to the executive:

    • such executive’s salary and bonus which have been earned but not yet paid; and

    • settlement of the executive’s vested deferral account balance, in accordance with its terms.

         In addition, the executive will receive continuation of welfare benefits for two years upon his or her termination unless termination is due to death, disability, termination by the company for “cause” or by the executive without “good reason”.

         If, within two years after a change in control of the combined company, the executive’s employment is terminated without “cause” (other than due to death or disability) or the executive resigns under circumstances which constitute a “termination without cause” (as defined in the executive’s term sheet), the executive is entitled to receive benefits that include:

    • an aggregate severance payment equal to 1.5 times the sum of such executive’s base salary and target bonus;

    • settlement of 100% of the executive’s deferral account balance;

    • full vesting and settlement of such executive’s restricted stock unit award;

    • full vesting of all restricted or deferred stock awards and stock options (other than awards under CVS’ Partnership Equity Program); and

    • the balance of any incentive awards earned as of December 31 of the prior year but not yet paid.

         In addition, in the event of certain terminations of employment the executive will receive payment of accrued and pro rata bonus amounts relating to the period prior to termination and continuation of welfare benefits for up to two years.

         If any of the total payments made to an executive covered by the term sheets as a result of the merger or which are credited to his or her deferral account as described above would be subject to the excise tax under Section 4999 of the Internal Revenue Code, CVS has agreed to make a gross-up payment to such executive such that, after taking into account all taxes under Section 4999 applicable to such executive, such executive retains an amount of the gross-up payment equal to the excise tax imposed on the total payments or credits to his or her deferral account.

          Caremark Synergy-Achievement Supplemental Bonus Plan

         The Caremark Synergy-Achievement Supplemental Bonus Plan was adopted by the Caremark board of directors to provide an incentive for certain designated executives of Caremark (1) to exceed the synergy-achievement targets which were set by Caremark’s Compensation Committee in consultation with Mr. Crawford following Caremark’s acquisition of AdvancePCS, (2) to meet cumulative earnings per share targets for the fiscal years 2004 and 2005 and (3) to remain employed by Caremark until all amounts due under the plan had been paid out. Under the terms of the Caremark Synergy—Achievement Supplemental Bonus Plan all synergy achievement targets and cumulative earnings per share targets have already been met, and one-half of each participant’s bonus was paid prior to April 1, 2006, and the remaining one-half is payable no later than April 1, 2007 to each participant remaining employed by Caremark at the time of payment. If the merger, which qualifies as a change in control under the bonus plan, is completed prior to payment of the remaining installment due by April 1, 2007, then the

    92






    second half of the bonus payment would be accelerated and would become payable to each participant remaining employed by Caremark at the time of payment and, to the extent the total payments made to a participant would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, Caremark will make a gross-up payment to such participant such that, after taking into account all taxes under Section 4999 applicable to such participant, such participant retains an amount of the gross-up payment equal to the excise tax imposed on the total payments. The approximate cash amount that will be paid under this bonus plan (not including any gross-up payments) for each named executive officer is: $810,000 for Mr. Hardin, $787,500 for Mr. McLure and $712,500 for Mr. Mladenovic, respectively, and for Caremark’s executive officers other than its named executive officers: $2,980,000 in the aggregate. Neither Mr. Crawford nor Mr. Spalding is a participant in the plan.

          Supplemental Executive Retirement Plan

         Mr. Crawford participates in Caremark’s Supplemental Executive Retirement Plan and he became fully vested in all benefits payable under the plan in November of 2006. This plan entitles Mr. Crawford to a benefit equal to 60% of his “final average compensation” (defined as the average of his highest monthly base salary during any 36-month period during the 72 months preceding his termination) and becomes payable on a monthly basis on the first of the month following Mr. Crawford’s termination of employment with Caremark. The monthly payment amount is reduced by 1/96 for each full month that benefits commence prior to Mr. Crawford reaching the age of 60. At Mr. Crawford’s option, the benefits can be paid in the form of a joint and survivor annuity as specified in the plan or as a life annuity or in six annual installments.

         The merger will constitute a change in control under the plan. Under the plan, upon a change in control, Caremark is required to establish an irrevocable trust and to fund such trust in an amount to ensure that the fair market value of the trust corpus, including any previous contributions made to the trust, equals the present value of the accrued benefits under the plan as of the effective date of the change in control. Mr. Crawford intends to resign his employment on completion of the merger and thereafter will serve as chairman of the board of directors of the combined company. Under the terms of the plan, his monthly payments will begin following his termination of employment and, due to the occurrence of the change in control, will not be subject to reduction despite the commencement of payments prior to Mr. Crawford reaching the age of 60.

          Survivor Benefit Agreement

         Mr. Crawford and Caremark have entered into a Survivor Benefit Agreement. Upon the termination of Mr. Crawford’s employment for any reason other than his death, Caremark is obligated to transfer to Mr. Crawford ownership of an insurance policy with a specified minimum death benefit at the time of such transfer equal to $17 million and a minimum cash value at the time of the transfer of $3,666,256 if the termination occurs on or before November 1, 2007 and $4,527,827 if the termination occurs after November 1, 2007. Upon completion of the transfer, Caremark’s obligation to pay a death benefit to Mr. Crawford’s beneficiaries under his employment agreement ceases. If Mr. Crawford recognizes taxable income for federal tax purposes at the time of the transfer of the insurance policy, Caremark is obligated to pay Mr. Crawford a tax gross-up amount equal to the amount of federal income taxes, including taxes attributable to payment of the gross-up amount.

          Special Retirement Plan

         The Special Retirement Plan is an unfunded, non-qualified benefit plan that will provide certain executive officers of Caremark with monthly benefits upon retirement, disability or a change in control of Caremark. Six of Caremark’s executive officers participate in the plan: Messrs. Clemens, Karro, Joyner, McLure, Mladenovic and Spalding. The benefit generally payable under the plan is equal to the product of (1) 2.5% of the average annual base salary paid to a participant over the 36-month period preceding his retirement date and (2) the participant’s years of service, up to a maximum of 20 years of service. The plan provides that a participant will continue to accrue years of service following completion of the merger but the plan remains subject to amendment or termination. Generally, to receive benefits under the plan, a participant would be required to be continuously employed by Caremark until the earlier of disability or reaching age 58 with 15 years of service. If, following the merger, the combined company (1) fails to expressly confirm that the participant will receive his accrued benefit under the plan within 60 days of the participant’s request for such confirmation or (2) terminates a participant’s employment within six months following

    93






    the completion of the merger, then the participant is deemed to have met the continuous employment requirement under the plan.

          Caremark Deferred Compensation Plan

         If, within six months of the completion of the merger, the combined company terminates the employment of a participant in the plan, such participant’s account would be payable automatically in one lump sum payment.

          Caremark Director Deferred Compensation Plan

         The Caremark Director Deferred Compensation Plan permits Caremark’s outside directors to defer their fees and offers a 15% premium on any fees that are deferred under the plan. The total deferred fees plus the premium are converted into a number of units, which are equal in value to shares of Caremark common stock. The participant’s account is paid as soon as practicable after the earlier to occur of (1) completion of a “change in control” (as defined in the plan) or (2) the cessation of a director’s status as an outside director on the Caremark board of directors. The merger will qualify as a change of control under the terms of the plan, and the account of each outside director of Caremark (including each outside director of Caremark who will continue as a member of the CVS/Caremark board of directors) will be paid as soon as practicable on the completion of the merger.

          CareStock Employee Stock Purchase Plan

         Under the CareStock Employee Stock Purchase Plan, employees of Caremark and its subsidiaries are eligible to purchase Caremark common stock at a price equal to 85% of the closing price of Caremark common stock on the applicable purchase date. Each employee may purchase annually up to $25,000 of Caremark common stock under this plan. Typically, Caremark common stock is purchased under this plan on the last trading date of any ordinary pay period for employees of Caremark and its subsidiaries. Under the terms of the plan, the last trading date immediately preceding or coinciding with a “change in control” of Caremark will be a purchase date on which employees may purchase Caremark common stock under the plan. The completion of the merger will constitute a change in control under the terms of the CareStock Employee Stock Purchase Plan.

          Caremark Retention Program

         Caremark intends to adopt a limited retention program to help ensure the retention of key employees below the level of senior vice president following the completion of the merger. An aggregate amount not to exceed $10 million will be made available for awards under the retention program. Caremark’s named executive officers will not be entitled to participate in this retention program.

          Insurance and Indemnification

         The merger agreement provides that, following the merger, the combined company will, to the extent permitted by law, indemnify and hold harmless all past and present officers and directors of Caremark and its subsidiaries to the same extent such individuals are indemnified pursuant to Caremark’s certificate of incorporation and bylaws in effect as of the date of the merger agreement, or to the fullest extent permitted by law, in each case for acts and omissions occurring at or prior to the effective time of the merger. The combined company also will continue to maintain for a period of six years after the completion of the merger, policies of directors’ and officers’ liability insurance with respect to claims arising from acts or omissions occurring prior to the completion of the merger on terms with respect to coverage and amounts no less favorable than the terms of the directors’ and officers’ liability insurance policies maintained by Caremark prior to the completion of the merger, but in no event will the combined company be required to pay in any one year an amount in excess of a specified percentage of the annual premiums paid by Caremark for such insurance in the last full fiscal year. If the annual premiums of such insurance coverage exceed such amount, the combined company will obtain a policy with at least the greatest coverage available for a cost not exceeding such amount.

    94






    Accounting Treatment

         The merger will be accounted for using the purchase method of accounting under U.S. GAAP. Under the purchase method of accounting, CVS will be considered the acquiror of Caremark for accounting purposes and the total purchase price will be allocated to the assets acquired and liabilities assumed from Caremark based on their fair values as of the date of the completion of the merger and any excess of purchase price over those fair values will be recorded as goodwill. Reported financial condition and results of operations of CVS issued after completion of the merger will reflect Caremark’s balances and results after completion of the merger, but will not be restated retroactively to reflect the historical financial position or results of operations of Caremark. Following the completion of the merger, the earnings of the combined company will reflect purchase accounting adjustments, including increased amortization expense for acquired intangible assets.

    Board of Directors and Management of CVS/Caremark Following the Merger; Headquarters

         Prior to the effective time of the merger, CVS and Caremark will determine the size of the CVS/Caremark board of directors. At the effective time of the merger, the CVS/Caremark board of directors will consist of an equal number of directors designated by each of CVS and Caremark. The CVS/Caremark board of directors will have, at the effective time of the merger, an audit committee, a management planning and development committee, a nominating and corporate governance committee and an executive committee. At the effective time of the merger, the chairman of the audit committee will be designated by former Caremark directors that are members of the CVS/Caremark board of directors and the chairman of each of the management, planning and development committee and nominating and corporate governance committee will be designated by former CVS directors that are members of the CVS/Caremark board of directors. At the effective time of the merger, the executive committee will consist of four members: E. Mac Crawford, Thomas M. Ryan, one member appointed by the former CVS directors and one member appointed by the former Caremark directors.

         As of the effective time of the merger, E. Mac Crawford will be the chairman of the CVS/Caremark board of directors and Thomas M. Ryan will be the chief executive officer of CVS/Caremark and a director of the combined company. In addition, as of the effective time of the merger, the senior management of the combined company will also include David B. Rickard as the chief financial officer of the combined company and Howard A. McLure as the president of its pharmacy services business.

         See “—Interests of Caremark Executive Officers and Directors in the Merger” beginning on page 86 and “Interests of CVS Executive Officers and Directors in the Merger” beginning on page 74 for a description of the material interests of executive officers and directors of Caremark and CVS, respectively, in the merger that are in addition to, or different than, their interests as stockholders. Additional information about the current directors and executive officers of CVS can be found in the “Corporate Governance and Related Matters–Director Nominations”, “Corporate Governance and Related Matters–Director Compensation”, “Corporate Governance and Related Matters–Share Ownership of Directors and Certain Executive Officers” and “Executive Compensation and Related Matters” in the definitive proxy statement for CVS’ 2006 Annual Meeting of stockholders filed with the SEC on March 24, 2006, which is incorporated by reference into this document. Additional information about the current directors and executive officers of Caremark can be found in the “About the Meeting—Item 1: Election of Directors,” “General Information About the Company—Directors Continuing in Office,” “General Information About the Company—Executive Officers” and “General Information About the Company—Stock Ownership of Directors and Executive Officers” in the definitive proxy statement for Caremark’s 2006 Annual Meeting of Stockholders filed with the SEC on April 7, 2006, which is incorporated by reference into this document. See “Where You Can Find More Information” beginning on page 158.

         Following completion of the merger, the combined company’s corporate headquarters will be located in Woonsocket, Rhode Island. In addition, the headquarters of the combined company’s pharmacy services business will be located in Nashville, Tennessee and any decision to change the location of the headquarters of the pharmacy services business prior to the third anniversary of the completion of the merger will require the approval of three-quarters of the directors of the combined company.

    95






    Repurchases of Caremark Common Stock

         Caremark may, from time to time, after this document is first filed with the SEC and before the completion of the merger, as price and conditions warrant, repurchase shares of Caremark common stock pursuant to the share repurchase program which previously has been approved by the Caremark board of directors. The timing and nature of these share repurchases will depend on market conditions and will be subject to limitations imposed by, and compliance with, the merger agreement and applicable federal and state securities laws.

    Federal Securities Laws Consequences; Stock Transfer Restriction Agreements

         All shares of CVS/Caremark common stock that Caremark stockholders receive in the merger will be freely transferable, except for shares of CVS/Caremark common stock received by persons who are deemed to be “affiliates” of Caremark under the Securities Act and the related SEC rules and regulations, at the time of the Caremark stockholders’ meeting. These “affiliates” may resell their shares of CVS/Caremark common stock only in transactions permitted by Rule 145 under the Securities Act or as otherwise allowed under that Act. Persons who may be deemed to be affiliates of Caremark for these purposes generally include individuals or entities that control, are controlled by, or are under common control with Caremark and may include some officers, directors and principal stockholders of Caremark. The merger agreement requires Caremark to use commercially reasonable efforts to deliver or cause to be delivered to CVS on or before the effective time of the merger from affiliates of Caremark an executed letter agreement to the effect that those persons will not offer or sell or otherwise dispose of any shares of CVS/Caremark common stock issued to them in the merger in violation of the Securities Act or the related SEC rules and regulations.

         Under Rule 145, former Caremark stockholders who were affiliates of Caremark at the time of the Caremark special meeting and who are not affiliates of CVS/Caremark after completion of the merger, may sell their CVS/Caremark common stock at any time subject to the volume and manner of sale limitations of Rule 144 under the Securities Act. Further, so long as such former Caremark affiliates are not considered affiliates of CVS/Caremark following completion of the merger, and a period of at least one year has elapsed from completion of the merger, such former affiliates may sell their CVS/Caremark common stock without regard to the volume and manner of sale limitations of Rule 144 under the Securities Act so long as there is adequate current public information available about CVS/Caremark in accordance with Rule 144. After a period of two years has elapsed from the completion of the merger, and so long as such former affiliates are not affiliates of CVS/Caremark and have not been for at least three months prior to such sale, such former affiliates may freely sell their CVS/Caremark common stock. Former Caremark stockholders who become affiliates of CVS/Caremark after completion of the merger will still be subject to the volume and manner of sale limitations of Rule 144 under the Securities Act until each such stockholder is no longer an affiliate of CVS/Caremark.

         This document does not cover any resales of the shares of CVS/Caremark common stock to be received by Caremark stockholders upon completion of the merger, and no person is authorized to make any use of this document in connection with a resale.

    No Appraisal Rights

         Stockholders of a corporation that is proposing to merge or consolidate with another entity are sometimes entitled to appraisal rights in connection with the proposed merger, depending on the circumstances. Appraisal rights confer on stockholders who oppose the merger and properly demand appraisal the right to receive the fair value for their shares as determined in a judicial appraisal proceeding, which may be different from what is being offered to them in the merger.

         Under Section 262 of Delaware General Corporation Law, appraisal rights are not available for shares of stock, such as Caremark common stock, which were, at the record date fixed to determine the stockholders entitled to receive notice of and to vote on the agreement of merger, either (1) listed on a national securities exchange such as the NYSE or (2) held of record by more than 2,000 holders and where the stockholders will receive shares of stock of another corporation, which shares of stock will be listed on a national securities exchange such as the NYSE. Accordingly, Caremark stockholders do not have appraisal rights in connection with the merger.

    96






         CVS stockholders also do not have appraisal rights in connection with the merger because CVS itself is not directly involved in the merger, but instead is conducting the merger through Twain MergerSub Corp., a Delaware corporation and wholly owned subsidiary of CVS formed for the purpose of the merger.

         The foregoing discussion is not a complete statement of law pertaining to appraisal rights under Delaware law and is qualified in its entirety by reference to Delaware law.

    Caremark Warrants

         In connection with its acquisition of AdvancePCS in 2004, Caremark assumed warrants to purchase 86,000 shares of Caremark common stock at an exercise price per share equal to $6.93, which are referred to as the Caremark warrants. In the merger, all outstanding Caremark warrants will be assumed by CVS, and will entitle the holder to acquire shares of CVS/Caremark common stock on the same terms and conditions as in effect immediately before the effective time of the merger, except that each of the warrants will then be exercisable for that number of shares of CVS/Caremark common stock equal to the number of shares of Caremark common stock previously subject to the corresponding Caremark warrant multiplied by 1.670 (rounded down to the nearest whole share) at an exercise price equal to the current exercise price of the corresponding Caremark warrant divided by 1.670 (rounded up to the nearest whole cent).

    Merger-Related Litigation

         In November 2006, the Iron Workers of Western Pennsylvania Pension Plan filed a purported class action lawsuit purportedly on behalf of Caremark stockholders in the United States District Court for the Middle District of Tennessee against Caremark and its directors. The complaint alleged, among other things, that the directors breached their fiduciary duties by entering into the proposed merger with CVS. The plaintiff sought, among other things, preliminary and permanent injunctive relief to prevent the proposed merger, to direct the defendants to obtain a transaction which is in the best interests of Caremark stockholders, and to impose a constructive trust upon any benefits improperly received by the defendants. In December 2006, the plaintiff moved for a temporary restraining order enjoining certain provisions of the merger agreement, expedited discovery, and an order to show cause why the proposed merger should not be preliminary enjoined. On December 22, 2006, the court denied the plaintiff’s motion for a temporary restraining order. In January 2007, the defendants moved to stay the lawsuit. On January 5, 2007, the court stayed the lawsuit, denied the plaintiff’s motion to expedite discovery and for an order to show cause, and administratively closed the case. The Sheetmetal Workers Local 28 Pension Fund also filed a purported class action lawsuit in the Chancery Court of Davidson County, Tennessee against Caremark and its directors. The complaint alleges, among other things, that the directors breached their fiduciary duties in approving the proposed merger. The plaintiff seeks, among other things, a declaration that the directors breached their fiduciary duties and injunctive relief preventing the proposed merger. In December 2006, the plaintiff sought to transfer the case to the Circuit Court for Davidson County, Tennessee and to consolidate it with the pending In Re: Caremark Rx, Inc. Stock Option Litigation, as described below. The defendants opposed the proposed transfer and consolidation. On January 12, 2007, the Circuit Court denied the proposed transfer and consolidation.

         In December 2006, Laurence M. Silverstein filed a purported class action lawsuit purportedly on behalf of Caremark stockholders relating to the proposed merger between Caremark and CVS in the United States District Court for the Middle District of Tennessee. The suit is brought against Caremark, its directors, CVS, and CVS’ chief executive officer. The complaint alleges, among other things, that the Caremark directors breached their fiduciary duties by entering into the proposed merger with CVS and that the CVS defendants aided and abetted such breaches of duty. The plaintiff seeks, among other things, preliminary and permanent injunctive relief to prevent the proposed merger, to direct the defendants to obtain a transaction which is in the best interests of Caremark stockholders, and to impose a constructive trust upon any benefits improperly received by the defendants. In January 2007, the plaintiff filed an amended class action complaint and moved for expedited discovery and preliminary injunctive relief. The amended class action complaint adds allegations that the joint proxy statement/prospectus filed on December 19, 2006 omits certain material information. On January 8, 2007, the court stayed the lawsuit and administratively closed the case. On January 10, 2007, the plaintiff moved to vacate the stay order. That motion, which is opposed, is pending.

    97






         The Louisiana Municipal Police Employees’ Retirement System also filed a purported class action lawsuit purportedly on behalf of Caremark stockholders in the Delaware Court of Chancery against Caremark’s directors and CVS. The complaint alleges, among other things, that the directors breached their fiduciary duties by entering into the proposed merger with CVS. The complaint also alleges that the joint proxy statement/prospectus filed on December 19, 2006 omits certain material information. The plaintiff seeks, among other things, preliminary and permanent injunctive relief to prevent the proposed merger. The lawsuit was amended in January 2007 to add the R.W. Grand Lodge of Free & Accepted Masons of Pennsylvania as a plaintiff and to add Caremark Rx, Inc. as a defendant. A hearing on the plaintiffs’ request for preliminary injunctive relief is currently scheduled for February 16, 2007, with the understanding that the plaintiffs may seek an earlier hearing date in the event that the Caremark stockholder meeting is scheduled before February 20, 2007.

         In January 2007, Express Scripts, Inc., which is referred to as Express Scripts, and Skadden, Arps, Slate, Meagher & Flom LLP, which is referred to as Skadden, filed a lawsuit in the Delaware Court of Chancery against Caremark, its directors, CVS, and AdvancePCS. The complaint alleges, among other things, that the directors breached their fiduciary duties by entering into the proposed transaction with CVS. The plaintiffs seek, among other things, declaratory relief and preliminary and permanent injunctive relief to prevent the proposed merger. The plaintiffs also seek declaratory relief holding that Skadden’s representation of Express Scripts does not violate Skadden’s professional, ethical, or contractual obligations. The plaintiffs have moved to have their lawsuit coordinated with the earlier filed lawsuit in the Delaware Court of Chancery as described in the preceding paragraph. That motion is pending.

         In addition to these recently filed lawsuits, a purported second amended shareholder derivative and class action complaint purportedly on behalf of Caremark stockholders was filed in November 2006 by the plaintiffs in the pending In Re: Caremark Rx, Inc. Stock Option Litigation in the Circuit Court for Davidson County, Tennessee. The purported second amended complaint includes purported class action allegations challenging the proposed merger and adds CVS as a defendant. Among other things, the purported second amended complaint alleges that the Caremark directors approved the merger agreement to avoid personal liability in the pending derivative litigation relating to the alleged backdating of stock options. The purported second amended complaint also alleges that CVS aided and abetted the alleged wrongdoing by the directors of Caremark. The plaintiffs seek, among other things, a declaration that the directors breached their fiduciary duties, injunctive relief preventing the defendants from completing the proposed merger, imposition of a constructive trust upon any illegal profits received by the defendants, and punitive damages. In December 2006, the plaintiffs moved for leave to file a third amended shareholder derivative and class action complaint and moved for expedited discovery. In January 2007, the defendants moved to stay the litigation of claims relating to the proposed merger, which the court granted on January 12, 2007. The plaintiffs will be permitted to file an amended complaint addressing only their alleged stock options claims and will not be permitted to seek relief with respect to the proposed merger.

         In November 2006, the plaintiffs in the pending In Re: Caremark Rx, Inc. Derivative Litigation in the United States District Court for the Middle District of Tennessee moved for leave to file a first amended shareholder derivative and class action complaint to add class action allegations challenging the proposed merger. Among other things, the proposed first amended complaint alleges that the Caremark directors approved the merger agreement to avoid personal liability in the pending derivative litigation relating to the alleged backdating of stock options. In the proposed first amended complaint, the plaintiffs seek, among other things, a declaration that the proposed merger is unfair to the plaintiffs, injunctive relief preventing the defendants from completing the proposed merger, and imposition of a constructive trust upon any illegal profits received by the defendants. The plaintiffs’ motion for leave to amend, which is opposed, is pending.

         Caremark believes the claims made in these stockholder lawsuits lack merit and intends to defend them vigorously. CVS believes the allegations pertaining to CVS in the stockholder lawsuits are void of merit and intends to defend them vigorously.

    MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE CAREMARK SPECIAL
    CASH DIVIDEND AND THE MERGER

         The following discussion summarizes the material U.S. federal income tax consequences of the special cash dividend and the merger to holders of Caremark common stock and CVS common stock.

         This discussion addresses only those Caremark stockholders that hold their Caremark common stock as a capital asset and does not address all aspects of federal income taxation that may be relevant to a holder of Caremark common stock in light of that stockholder’s particular circumstances or to a stockholder subject to special rules, such as:

    • a stockholder that is not a citizen or resident of the United States;

    • a financial institution or insurance company;

    • a mutual fund;

    • a tax-exempt organization;

    • a dealer or broker in securities or foreign currencies;

    • a trader in securities that elects to apply a mark-to-market method of accounting;

    • a stockholder that holds Caremark common stock as part of a hedge, appreciated financial position, straddle, conversion, or other risk reduction transaction; or

    • a stockholder that acquired Caremark common stock pursuant to the exercise of options or similar derivative securities or otherwise as compensation.

         If a partnership holds Caremark common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partners and the activities of the partnership. A partner in a partnership holding Caremark common stock should consult its tax advisor.

         The following discussion is not binding on the Internal Revenue Service, referred to as the IRS. It is based on the Internal Revenue Code of 1986, as amended, applicable Treasury regulations, administrative interpretations and court decisions, each as in effect as of the date of this document and all of which are subject to change, possibly with retroactive effect. The tax consequences under U.S. state and local and foreign laws and U.S. federal laws other than U.S. federal income tax laws are not addressed.

         Holders of Caremark common stock are strongly urged to consult their tax advisors as to the specific tax consequences to them of the special cash dividend and the merger, including the applicability and effect of U.S. federal, state and local and foreign income and other tax laws in light of their particular circumstances.

    General

         CVS and Caremark have structured the merger to qualify as a reorganization for U.S. federal income tax purposes. On the date this registration statement becomes effective, CVS will have received a written opinion from Davis Polk & Wardwell, and Caremark will have received a written opinion from King & Spalding LLP, both to the effect that for U.S. federal income tax purposes, the merger will constitute a reorganization within the meaning of section 368(a) of the Internal Revenue Code. It is a condition to the completion of the merger that Davis Polk & Wardwell and King & Spalding LLP confirm their respective opinions as of the closing date of the merger. Neither CVS nor Caremark intends to waive this condition. These opinions each rely on assumptions, including assumptions regarding the absence of changes in existing facts and law and the completion of the merger in the manner contemplated by the merger agreement, and representations and covenants made by CVS and Caremark, including those contained in certificates of officers of CVS and Caremark. The accuracy of those representations, covenants or assumptions may affect the conclusions set forth in these opinions, in which case the tax consequences

    99






    of the merger could differ from those discussed here. Opinions of counsel neither bind the IRS nor preclude the IRS from adopting a contrary position. No ruling has been or will be sought from the IRS on the tax consequences of the merger.

    U.S. Federal Income Tax Consequences to Caremark Stockholders

       Caremark Special Cash Dividend

         Although the tax treatment of the Caremark special cash dividend is unclear, Caremark and CVS intend to report the special cash dividend as a distribution with respect to Caremark common stock. It is possible, however, that the IRS could treat the Caremark special cash dividend as additional consideration received in connection with the merger, with the tax consequences described below under “—Merger.” If the special cash dividend is treated as a distribution with respect to Caremark common stock, the gross amount paid to holders of Caremark common stock will be characterized as dividend income to the extent that the Caremark special cash dividend does not exceed Caremark’s current and accumulated earnings and profits (as determined for U.S. federal income tax purposes).

         Dividend income will be includible in the gross income of a holder of Caremark common stock on the day received. Under current law this income will generally be taxed to non-corporate stockholders at the rates applicable to long-term capital gains (with a 15% maximum federal rate), provided that a minimum holding period and other requirements are satisfied. Corporate stockholders may be entitled to a dividends-received deduction with respect to distributions treated as dividend income for U.S. federal income tax purposes, subject to limitations and conditions.

         Distributions to a stockholder in excess of current and accumulated earnings and profits, if any, will be treated first as a return of capital that reduces such holder’s tax basis in the Caremark common stock, and then as gain from the sale or exchange of Caremark common stock. This gain would be capital gain provided that such stockholder holds the Caremark common stock as a capital asset as of the time of the Caremark special cash dividend.

       Merger

         Subject to the qualifications and limitations set forth in “Material Federal Income Tax Consequences of the Caremark Special Cash Dividend and the Merger—General” beginning on page 99, the material U.S. federal income tax consequences of the merger will be as follows:

    • A holder of Caremark common stock will not recognize gain or loss upon the exchange of that stockholder’s Caremark common stock for CVS/Caremark common stock in the merger, except (i) that gain or loss will be recognized on the receipt of cash instead of a fractional share of CVS/Caremark common stock (as described below), and (ii) if the Caremark special cash dividend is treated as additional merger consideration rather than as a distribution with respect to Caremark common stock, gain will be recognized in an amount equal to the lesser of (a) the amount of the Caremark special cash dividend and (b) the excess, if any, of the sum of the amount of such cash and the fair market value of the CVS/Caremark common stock received in the merger, over that holder’s tax basis in the Caremark common stock exchanged. Any gain recognized will generally be long-term capital gain if the holder’s holding period for the Caremark common stock surrendered in the merger is more than one year at the completion of the merger. Nevertheless, even if the Caremark special cash dividend were treated as additional consideration received in connection with the merger, in certain cases gain recognized in respect of the special cash dividend could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Internal Revenue Code, in which case such gain would be treated as dividend income.

    • If a holder of Caremark common stock receives cash instead of a fractional share of CVS/Caremark common stock, the holder will be required to recognize gain or loss, measured by the difference between the amount of cash received and the portion of the tax basis of that holder’s Caremark common stock allocable to that fractional share of CVS/Caremark common stock. This gain or loss will be a capital gain or loss and will be a long-term capital gain or loss if the holding period for the Caremark common stock

    100






      exchanged for the fractional share of CVS/Caremark common stock is more than one year at thecompletion of the merger.

    • A holder of Caremark common stock will have a tax basis in the CVS/Caremark common stock received in the merger equal to (1) the tax basis of the Caremark common stock surrendered by that holder in the merger, reduced by (2) any tax basis of the Caremark common stock surrendered that is allocable to a fractional share of CVS/Caremark common stock for which cash is received, and, if the Caremark special cash dividend is treated as additional merger consideration rather than as a distribution with respect to Caremark common stock, reduced by (3) the amount of such special cash dividend, and increased by (4) the amount of gain recognized (excluding any gain recognized as a result of cash received in lieu of a fractional share).

    • The holding period for the CVS/Caremark common stock received in exchange for shares of Caremark common stock in the merger will include the holding period for the shares of Caremark common stock surrendered in the merger.

         In the case of a holder of Caremark common stock that holds shares of Caremark common stock with differing tax bases and/or holding periods, the preceding rules must be applied to each identifiable block of Caremark common stock.

    Information Reporting and Backup Withholding

         A holder of Caremark common stock may be subject to information reporting and backup withholding in connection with the Caremark special cash dividend and any cash payments received instead of a fractional share of CVS/Caremark common stock, unless such holder provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the holder’s U.S. federal income tax liability, provided the required information is furnished.

         This discussion is intended to provide only a general summary of the material U.S. federal income tax consequences of the merger, and is not a complete analysis or description of all potential U.S. federal income tax consequences of the merger. This discussion does not address tax consequences that may vary with, or are contingent on, individual circumstances. In addition, it does not address any non-income tax or any foreign, state or local tax consequences of the merger. Accordingly, Caremark strongly urges each holder of Caremark common stock to consult his or her tax advisor to determine the particular U.S. federal, state or local or foreign income or other tax consequences to that stockholder of the merger.

    U.S. Federal Income Tax Consequences to CVS Stockholders

         There will be no U.S. federal income tax consequences to a holder of CVS common stock as a result of the merger.

    101






    REGULATORY AND OTHER APPROVALS REQUIRED FOR THE MERGER

         Under the merger agreement, each of CVS and Caremark has agreed to use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable law to consummate the merger and the other transactions contemplated by the merger agreement, including (1) preparing and filing as promptly as practicable with any governmental authority or other third party all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents and (2) obtaining and maintaining all approvals, consents, waivers, licenses, orders, registrations, permits, authorizations, clearances and other confirmations required to be obtained from any governmental authority or other third party that are necessary, proper or advisable to consummate the merger and the other transactions contemplated by the merger agreement.

          Notwithstanding the foregoing, CVS, Caremark and their respective subsidiaries are not required:

    • to enter into any settlement, undertaking, consent decree, stipulation or agreement with any governmental authority in connection with the merger and the other transactions contemplated by the merger agreement, or

    • to divest or otherwise hold separate (including by establishing a trust or otherwise), or take any other action (or otherwise agree to do any of the foregoing) with respect to any of its subsidiaries or any of their respective affiliates’ businesses, assets or properties,

    which, in either case, would reasonably be expected to (1) materially and adversely diminish the benefits expected to be derived by CVS or Caremark as of November 1, 2006, the date of entering into the merger agreement, from the combination of CVS and Caremark via the merger (such combined business to be taken as a whole), in such a manner that CVS or Caremark would not have entered into the merger agreement in the face of such materially and adversely diminished benefits or (2) otherwise have a material adverse effect after the effective time on the combined company.

         A condition to CVS’ and Caremark’s respective obligations to consummate the merger is that any waiting period applicable to the merger under the HSR Act will have expired or been terminated. A further condition is that all required governmental regulatory consents and approvals will have been obtained except those that in the aggregate fall below the materiality standard described in the immediately preceding paragraph. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114.

    U.S. Antitrust Filing

         Under the HSR Act and the rules and regulations promulgated thereunder, certain transactions, including the merger, may not be consummated unless certain waiting period requirements have expired or been terminated. Each of CVS and Caremark filed a Pre-Merger Notification and Report Form pursuant to the HSR Act with the Justice Department and the Federal Trade Commission on November 20, 2006. Under the HSR Act, the merger may not be consummated until 30 days after the initial filing (unless early termination of this waiting period is granted) or, if the Antitrust Division of the Department of Justice or the Federal Trade Commission issues a request for additional information, 30 days after CVS and Caremark have “substantially complied” with such request for additional information (unless this period is shortened pursuant to a grant of earlier termination). On December 20, 2006, the initial waiting period required under the HSR Act expired without a request for additional information from the Federal Trade Commission. Notwithstanding such expiration, at any time before the effective time of the merger, the Federal Trade Commission, the Justice Department or others could take action under the antitrust laws with respect to the merger, including seeking to enjoin the completion of the merger, to rescind the merger or to conditionally approve the merger upon the divestiture of assets of CVS or Caremark or to impose restrictions on the operations of the combined company post closing. There can be no assurance that the merger will not be challenged on antitrust grounds or, if such a challenge is made, that the challenge will not be successful. In addition, state antitrust authorities and private parties in certain circumstances may bring legal action under the antitrust laws seeking to enjoin the merger or seeking conditions to the completion of the merger. CVS and Caremark have been informed that Arizona, California, Florida, Illinois, Louisiana, Maine, Massachusetts, Missouri, Nebraska, New

    102






    York, Ohio, Pennsylvania, Rhode Island, Virginia and the District of Columbia, the states that had previously indicated they would be reviewing the merger from an antitrust perspective, will not pursue their review of the proposed merger. Under the merger agreement, subject to the conditions and limitations described above, CVS and Caremark have agreed to take all actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act.

         As indicated in “Risk Factors”, beginning on page 27, CVS’ and Caremark’s businesses are subject to numerous federal, state and local laws and regulations including, but not limited to, health care regulatory laws and regulations applicable to the following: the licensure and regulation of pharmacies and pharmacists and other health care professionals; Medicare, Medicaid and other government reimbursement programs; HIPAA; the storage, advertisement, promotion, sale and distribution of controlled substances and other products; and the like. Certain of these health care regulatory laws and regulations may require filings or approvals in connection with the completion of the merger; provided, however, that it is not expected that (i) any such filings or approvals would delay the merger or (ii) the failure to make any such filings or obtain any such approvals prior to the merger would have a material adverse effect on either of CVS or Caremark.

         Other than the filings described above, neither CVS nor Caremark is aware of any regulatory approvals required to be obtained, or waiting periods required to expire, to complete the merger. If CVS and Caremark discover that other approvals or waiting periods are necessary, CVS and Caremark will seek to obtain or comply with them in accordance with the merger agreement.

         To the extent that regulatory authorities require CVS and/or Caremark to divest assets, or impose other conditions or restrictions on the approval of the merger, that violate the conditions described above, the parties will assess such impact on the merger and either CVS or Caremark could decline to close under the merger agreement if such divestitures, conditions and restrictions would result in the failure of a condition to closing of the merger. CVS and Caremark can give no assurance that the required regulatory approvals will be obtained on terms that satisfy the conditions to the completion of the merger or within the time frame contemplated by CVS and Caremark. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 114.

    THE MERGER AGREEMENT

         The following is a summary of the material terms of the merger agreement. This summary does not purport to describe all the terms of the merger agreement and is qualified by reference to the complete merger agreement (including Amendment No. 1 to the merger agreement, dated as of January 16, 2007) which is attached as Annex A to this document and incorporated by reference. The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not this summary or any other information contained in this document. All stockholders of CVS and Caremark are urged to read the merger agreement carefully and in its entirety.

    Explanatory Note Regarding Summary of Merger Agreement and Representations and Warranties in the Merger Agreement

         The summary of the terms of the merger agreement is intended to provide information about the terms of the merger. The terms and information in the merger agreement should not be relied on as disclosures about CVS or Caremark without consideration to the entirety of public disclosure by CVS and Caremark as set forth in all of their respective public reports with the SEC. The terms of the merger agreement (such as the representations and warranties) govern the contractual rights and relationships, and allocate risks, between the parties in relation to the merger. In particular, the representations and warranties made by the parties to each other in the merger agreement have been negotiated between the parties with the principal purpose of setting forth their respective rights with respect to their obligation to close the merger should events or circumstances change or be different from those stated in the representations and warranties. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders under federal securities laws. Matters may change from the state of affairs contemplated by the representations and warranties. CVS and Caremark will provide additional disclosure in their public reports to the extent that they are aware of the existence of any material facts that are required to be disclosed under federal securities laws and will update such disclosure as required by federal securities laws.

    Structure of the Merger

         The merger agreement provides for the merger of Caremark with and into Twain MergerSub LLC, a wholly owned subsidiary of CVS that was formed for the purpose of the merger, with Twain MergerSub LLC surviving the merger. Twain MergerSub LLC was originally formed under the name Twain MergerSub Corp. as a Delaware Corporation and was converted into a limited liability company; its name has been changed to Twain MergerSub LLC in accordance with the merger agreement. Immediately following the merger, the surviving entity will remain a wholly owned subsidiary of CVS, CVS Corporation will be renamed “CVS/Caremark Corporation” and Twain MergerSub LLC will be renamed “Caremark Rx, L.L.C.”. The merger will become effective when Twain MergerSub LLC and Caremark file a certificate of merger with the Secretary of State of the State of Delaware (or at such later time as CVS and Caremark agree and specify in the certificate of merger). The time the merger becomes effective is referred to as the effective time of the merger. CVS and Caremark anticipate that the parties will make this filing as soon as practicable after the last of the conditions to the merger contained in the merger agreement has been satisfied or waived.

    Timing of Closing

         The closing will occur as soon as practicable, but in no event later than five business days after the day on which the last of the conditions set forth in the merger agreement has been satisfied or waived, unless CVS and Caremark agree to a different date. See “—Conditions to Completion of the Merger” beginning on page 114 for a more complete description of the conditions that must be satisfied or waived before closing.

    Merger Consideration

         At the effective time of the merger, each issued and outstanding share of Caremark common stock will be converted into the right to receive 1.670 shares of CVS/Caremark common stock. Caremark stockholders will receive cash in lieu of any fractional shares of CVS/Caremark common stock that would have otherwise been

    106






    received in the merger. See “—Fractional Shares” beginning on page 107. If, between the date of the merger agreement and the effective time of the merger, there is a reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend with respect to the capital stock of CVS or Caremark, the exchange ratio will be appropriately adjusted.

         CVS and Caremark expect that, upon completion of the merger, the Caremark stockholders immediately prior to the merger will own approximately 45.5% of the outstanding common stock of the combined company on a fully diluted basis, and the CVS stockholders immediately prior to the merger will own approximately 54.5% of the outstanding common stock of the combined company on a fully diluted basis.

    Exchange of Shares

         Before the effective time of the merger, CVS and Caremark will appoint an exchange agent to handle the exchange of Caremark common stock in the merger for CVS/Caremark common stock and the payment of cash in lieu of fractional shares of CVS/Caremark common stock. Promptly after the effective time of the merger, the exchange agent will send to each holder of Caremark common stock a letter of transmittal for use in the exchange and instructions explaining how to surrender stock certificates or transfer uncertificated shares of Caremark common stock to the exchange agent. Holders of Caremark common stock that surrender their stock certificates or transfer their uncertificated shares to the exchange agent, together with a properly completed letter of transmittal, will receive the appropriate merger consideration. You should not return stock certificates with the enclosed proxy card.

         After the effective time of the merger, holders of unexchanged shares of Caremark common stock will not be entitled to receive any dividends or other distributions payable by CVS/Caremark after the closing until their shares of Caremark common stock are surrendered. However, once those shares are surrendered, CVS/Caremark will pay the holder, without interest, any dividends with a record date after the effective time of the merger that were previously paid to CVS/Caremark stockholders or are payable at the time the shares of Caremark common stock are surrendered.

    Fractional Shares

         CVS/Caremark will not issue fractional shares of CVS/Caremark common stock in the merger. All fractional shares of CVS/Caremark common stock that a holder of shares of Caremark common stock would otherwise be entitled to receive as a result of the merger will be aggregated. For any fractional share that results from such aggregation, the exchange agent will pay the holder an amount of cash, without interest, equal to the fraction of a share of CVS/Caremark common stock to which the Caremark stockholder would be entitled in the merger multiplied by the closing sale price of a share of CVS/Caremark common stock on the first trading day immediately following the effective time of the merger.

    Caremark Stock Options

         All Caremark options, whether or not exercisable and whether or not vested and whether or not granted under a Caremark stock option plan or a legacy AdvancePCS stock option plan, that are outstanding as of the effective time of the merger, will remain outstanding following the effective time of the merger and will be assumed by CVS as described below.

         Prior to the effective time of the merger, the compensation committee of the Caremark board of directors will make adjustments to Caremark’s outstanding stock options to reflect the extraordinary cash dividend. At the effective time of the merger, each outstanding Caremark option will be converted into an option to acquire CVS/Caremark common stock on the same terms and conditions as the Caremark option before the effective time of the merger except that each option will allow the holder thereof to purchase a number of shares of CVS/Caremark common stock equal to (1) the number of shares of Caremark common stock subject to the Caremark option prior to the effective time of the merger multiplied by (2) 1.670, rounded down to the nearest whole share. In addition, upon the effective time of the merger, each option of the combined company will have an exercise price per share equal to (1) the aggregate exercise price required to purchase all shares of Caremark common stock subject to the Caremark option before the completion of the merger divided by (2) the number of shares of CVS/Caremark common stock subject to the option after completion of the merger, rounded up to the nearest whole cent.

    107






         CVS has agreed to take all action necessary to implement the conversion described above, including the reservation, issuance and listing of a sufficient number of shares of CVS/Caremark common stock for delivery upon exercise of these substitute options. CVS is required to prepare and file a registration statement on an appropriate form, or a post-effective amendment to a previously filed registration statement, with respect to the shares of CVS/Caremark common stock subject to the above options and, where applicable, is required to use all commercially reasonable efforts to have the registration statement declared effective as soon as practicable after the effective time of the merger, to maintain its effectiveness and to maintain the current status of the prospectus contained in it for so long as the options remain outstanding.

         The merger constitutes a change in control under the terms of each of Caremark’s stock option plans and agreements, other than legacy AdvancePCS stock option plans, therefore, each Caremark option (other than options issued under legacy AdvancePCS stock option plans) will vest and become fully exercisable at the effective time of the merger.

    Listing of CVS/Caremark Stock

         CVS has agreed to use commercially reasonable efforts to cause the shares of CVS/Caremark common stock to be issued in the merger to be approved for listing on the NYSE. The approval for listing of these shares on the NYSE is a condition to the obligations of CVS and Caremark to complete the merger, subject only to official notice of issuance. CVS/Caremark will continue to use the trading symbol “CVS” for the shares of CVS/Caremark common stock issuable to the Caremark stockholders in the merger.

    CVS Governance and Related Matters

         CVS has agreed to take the necessary corporate action so that, at the effective time of the merger:

    • The CVS/Caremark board of directors will be comprised of a number of members (which will be an even number) to be agreed on by CVS and Caremark.

    • The CVS/Caremark board of directors will be comprised of an equal number of directors selected by each of CVS and Caremark. The directors of CVS/Caremark selected by CVS are referred to as the CVS-designated directors and the directors of CVS/Caremark selected by Caremark are referred to as the Caremark-designated directors.

    • Thomas M. Ryan, the current chairman, president and chief executive officer of CVS, will be the chief executive officer and a director of CVS/Caremark. The removal of Mr. Ryan as chief executive officer of the combined company prior to January 2010 will require approval of three-quarters of the members of the CVS/Caremark board of directors.

    • E. Mac Crawford, the current chairman, president and chief executive officer of Caremark, will serve as the chairman of the board of directors and a director of CVS/Caremark.

    • The Caremark-designated directors will select the chairman of the CVS/Caremark audit committee and the CVS-designated directors will select the chairman of each of the CVS/Caremark compensation committee and the nominating and corporate governance committee.

    • The executive committee of the CVS/Caremark board of directors will consist of four members: Thomas M. Ryan, E. Mac Crawford and one member appointed by CVS-designated directors and one member appointed by the Caremark-designated directors.

    Representations and Warranties

         The merger agreement contains a number of substantially reciprocal representations and warranties made by each of CVS and Caremark to the other. The most significant representations and warranties relate to:

    • due incorporation, good standing and qualification;

    108






    • corporate authority to enter into the merger agreement and complete the merger;

    • approval and adoption of the merger agreement and related matters by the board of directors;

    • required stockholder vote to approve the merger;

    • required consents and filings with government entities;

    • absence of any breach of organizational documents, laws and agreements as a result of the merger;

    • capitalization;

    • ownership of subsidiaries;

    • accuracy and sufficiency of documents filed with the SEC;

    • conformity of the financial statements with applicable accounting principles and that the financial statements fairly present, in all material respects, the consolidated financial positions of CVS and Caremark;

    • sufficiency of internal controls;

    • environmental matters; and

    • inapplicability of Delaware takeover statutes to the merger.

         Significant portions of the representations and warranties of Caremark and CVS are qualified as to “materiality” or “material adverse effect”. Under the merger agreement, a material adverse effect means, when used in connection with CVS or Caremark, a material adverse effect on the business, financial condition or results of operation of CVS or Caremark and their respective subsidiaries, taken as a whole, except any such effect to the extent resulting from any of the following (but so long as, in the bullet points other than the first below, such effect does not have a materially disproportionate effect on CVS or Caremark, as the case may be, and their respective subsidiaries):

    • any change in the market price of the common stock of CVS or Caremark, as the case may be, after November 1, 2006 (excluding any underlying circumstance or effect that may have caused that change in market price);

    109






    • changes, circumstances or conditions generally affecting any industry in which CVS or Caremark, as the case may be, or any of their subsidiaries participate;

    • changes generally affecting the U.S. or global economic conditions or financial markets;

    • changes resulting from a change in U.S. GAAP;

    • changes resulting from any act of war or terrorism (or any escalation thereof); or

    • changes, facts, circumstances or conditions that can be shown to have been proximately caused by the announcement of the merger.

         The representations and warranties in the merger agreement do not survive the completion of the merger or the termination of the merger agreement.

    Certain Covenants

          CVS and Caremark have agreed to certain covenants in the merger agreement, including:

         No Solicitation. Each of CVS and Caremark has agreed that it and its subsidiaries and their respective officers, directors, employees and advisers will not:

    • solicit, initiate or take any action to knowingly facilitate or encourage the submission of any “acquisition proposal” of the type described below;

    • enter into or participate in any discussions or negotiations with or furnish any information relating to itself or any of its subsidiaries to or otherwise cooperate in any way with, or knowingly assist or encourage any third party seeking to make or who has made an acquisition proposal;

    • recommend to its stockholders an acquisition proposal or fail to make, withdraw or modify in a manner adverse to the other party its recommendation to its stockholders that, in the case of CVS stockholders, they approve the amendments of the CVS charter and the issuance of CVS/Caremark common stock to Caremark stockholders in the merger, or in the case of Caremark stockholders, they adopt the merger agreement and approve the merger, which in each case is referred to as a change in recommendation;

    • grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of itself or any of its subsidiaries;

    • enter into any agreement in principle, letter of intent, term sheet or other similar instrument relating to an acquisition proposal; or

    • propose publicly or agree to do any of the foregoing related to any acquisition proposal.

         However, either party is permitted to engage in discussions or negotiations with, and provide information to, any person in response to an unsolicited bona fide acquisition proposal that is reasonably likely to lead to a superior proposal if:

    • its special meeting to vote on the applicable stockholder proposals required to be approved by its stockholders to complete the merger has not occurred;

    • its board of directors determines in good faith by a majority vote, after receiving the advice of outside legal counsel, that failing to take such action would be inconsistent with its fiduciary duties to stockholders; and

    • it receives from such person an executed confidentiality agreement with terms no less favorable than those contained in the existing confidentiality agreement between CVS and Caremark.

    110






         CVS and Caremark must keep the other reasonably informed of the status and details of any acquisition proposal. Before changing its recommendation, CVS or Caremark, as applicable, must satisfy the conditions in the preceding paragraph and provide the other party with a period of five business days to adjust the terms of the merger agreement so as to enable it to proceed without changing its recommendation. Following such five business day period, if the board of directors of CVS or Caremark, as applicable, remains committed to changing its recommendation in favor of a superior proposal (as defined below), such party will be permitted to enter into a conditional merger agreement with the third party making the superior proposal that will only become effective upon (1) termination of the merger agreement in accordance with its terms as described herein and (2) payment by the third party, on behalf of CVS or Caremark, as applicable, of the termination fee set forth in the merger agreement. See “Termination Fees” below for more details regarding the termination fee payable under the merger agreement. However, until the termination of the merger agreement in accordance with its terms, (1) in no event will the party entering into such conditional merger agreement make any SEC or other regulatory filings in connection with the transactions contemplated by such conditional merger agreement and (2) the party entering into the conditional merger agreement will otherwise remain subject to all of its obligations under the merger agreement, including those described above in this section and “—Covenant to Recommend” and “—Reasonable Best Efforts Covenant” beginning on pages 111 and 112, respectively.

         An “acquisition proposal” is, with respect to either CVS or Caremark, any offer, proposal or inquiry relating to, or any third party indication of interest in, (1) any acquisition or purchase, direct or indirect, of 20% or more of the consolidated assets of that person and its subsidiaries or over 20% of any class of equity or voting securities of that person or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of that person, (2) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 20% or more of any class of equity or voting securities of that person or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of that person or (3) a merger, consolidation, share exchange, business combination, sale of substantially all the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving that person or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of that person.

         A “superior proposal” is a bona fide, unsolicited written acquisition proposal (which definition shall be read, for this purpose, without the word “inquiry”) for at least a majority of the outstanding shares of common stock of Caremark or CVS (as the case may be) on terms that the board of directors of such party determines in good faith by a majority vote, after consultation with its legal and financial advisors and taking into account such matters deemed relevant in good faith by such board of directors, including among other things, all the terms and conditions of the acquisition proposal, including any break-up fees, expense reimbursement provisions, conditions to completion and long-term strategic considerations, are more favorable from a financial point of view to the stockholders of such party than the merger and for which financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available by the board of directors of that party.

         Each party has agreed to terminate any discussions or negotiations with any person that began before November 1, 2006.

         Covenant to Recommend. CVS has agreed to recommend the approval by CVS stockholders of (1) a proposal to be effective upon completion of the merger, to amend the CVS charter, to increase the authorized number of shares of CVS common stock from 1 billion to 3.2 billion and to change the name of CVS Corporation to “CVS/Caremark Corporation” and (2) a proposal to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger on the terms and conditions set forth in the merger agreement, and to call a meeting of its stockholders for these purposes. The Caremark board of directors has agreed to recommend the approval by Caremark stockholders of a proposal to adopt the merger agreement and approve the merger, and has agreed to call a meeting of its stockholders for this purpose. Each party’s board of directors, however, can make a change in recommendation, including by approving, recommending or endorsing a potential superior proposal, if (1) it has not received the approval of its stockholders in connection with the merger, (2) it has received an unsolicited bona fide written acquisition proposal from a third party, (3) its board of directors has determined in good faith (after consultation with its outside legal counsel and financial advisors) that the acquisition proposal constitutes a superior proposal and (4) its board of directors, after consultation with outside legal counsel, determines in good faith that

    111






    failing to take such action would be inconsistent with its fiduciary duties to stockholders. Unless Caremark has otherwise terminated the merger agreement, whether or not (1) the CVS board of directors has made a change in recommendation or (2) an acquisition proposal has been publicly proposed or announced or otherwise submitted to CVS or any of its advisors, the CVS proposals described above in this paragraph must be submitted to CVS stockholders at a meeting of its stockholders called for this purpose. Unless CVS has otherwise terminated the merger agreement, whether or not (1) Caremark’s board of directors has made a change in recommendation or (2) an acquisition proposal has been publicly proposed or announced or otherwise submitted to Caremark or any of its advisors, the Caremark proposals described above in this paragraph must be submitted to Caremark stockholders at a meeting of its stockholders called for this purpose.

         Interim Operations of CVS and Caremark. Each of CVS and Caremark has undertaken a separate covenant that places restrictions on it and its subsidiaries until the later of either the effective time or the date the merger agreement is terminated. In general, CVS and its subsidiaries and Caremark and its subsidiaries are required to conduct their respective businesses in the ordinary course consistent with past practice and to use all commercially reasonable efforts to preserve intact their respective business organizations and relationships with third parties. The companies have also agreed to some specific restrictions which (subject to exceptions described in the merger agreement) are substantially, but not entirely, comparable, because, in a number of instances, an action is applicable to only one of the companies by nature. The most significant activities that each company has agreed not to do, and not to permit its subsidiaries to do, are as follows:

    • amend its organizational documents;

    • split, combine or reclassify its shares of capital stock or those of its subsidiaries;

    • declare dividends, except for regular quarterly cash dividends not in excess of $0.10 per share, in the case of Caremark common stock, and $0.03875 per share, in the case of CVS common stock;

    • issue, deliver or sell equity securities, options or other securities convertible into or exercisable for equity securities, except to a limited extent to employees or directors;

    • acquire or dispose of a material asset, except in the ordinary course or below certain dollar thresholds;

    • make any loans, advances or capital contributions to, or investments in, any other person;

    • create, incur or assume any indebtedness, other than in the ordinary course or under existing lines of credit;

    • enter into any agreement that limits or otherwise restricts in any material respect such party, or will restrict the combined company after the effective time of the merger;

    • grant or increase employee compensation or benefits, except for normal ordinary course increases consistent with past practice (but in no event including awards that will be enhanced or accelerated by the transactions contemplated by the merger agreement);

    • change its financial accounting or tax accounting policies; and

    • settle any legal proceedings that arise out of the transactions contemplated by the merger agreement.

         Reasonable Best Efforts Covenant. CVS and Caremark have agreed to use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to complete the merger and the other transactions contemplated by the merger agreement, including filing requisite documents with governmental entities or other third parties and obtaining and maintaining all necessary approvals, consents and authorizations. However, neither CVS nor Caremark is required to enter into a settlement or other agreement with any governmental entity in connection with the transactions contemplated by the merger agreement or divest or take any other action with respect to any of its businesses, assets or properties if the result would reasonably be expected to:

    112






    • materially and adversely diminish the benefits expected to be derived by the parties on the date of the merger agreement from the combination of CVS and Caremark via the merger (such combined business to be taken as a whole), in such a manner that either CVS or Caremark would not have entered into the merger agreement in the face of such materially and adversely diminished benefits, or

    • otherwise have a material adverse effect (but ignoring the exception for effects caused by the announcement of the merger in the definition of material adverse effect) after the effective time of the merger on CVS/Caremark and its subsidiaries, taken as a whole.

         To the extent that regulatory authorities require CVS and/or Caremark to divest assets, or impose other conditions or restrictions on the approval of the merger, that violate the conditions described above, either CVS or Caremark could decline to close under the merger agreement as a result of a failure of the satisfaction of a closing condition to the merger.

         Certain Employee Benefits Matters. The merger agreement provides that CVS will honor all accrued and vested benefit obligations to and contractual rights of current and former employees of Caremark and CVS and their respective subsidiaries under their respective existing employee plans, to the extent accrued and vested as of the effective time of the merger. CVS and Caremark, acting in good faith, will cooperate in reviewing their existing employee plans with a view towards developing appropriate employee benefit and compensation plans, which are referred to as the new benefit plans, after the effective time of the merger, which among other things, (1) will treat similarly situated employees (regardless of whether they were former CVS employees or former Caremark employees) on a substantially equivalent basis, taking into account all relevant factors and (2) will not discriminate between its employees who, at the effective time of the merger, were CVS employees or Caremark employees. CVS has agreed to adopt the new benefit plans, subject to customary rights to subsequently amend or terminate the plans as CVS/Caremark deems appropriate.

          The new benefit plans will provide for the following:

    • eligible participants will receive service credit for purposes of eligibility, participation, vesting and levels of benefits for all periods of employment with Caremark or CVS or any of their respective subsidiaries before the effective time of the merger;

    • all pre-existing conditions or limitations under any new benefit plan which is a welfare plan will be waived to the extent waived under the corresponding plan in which the employee participated immediately before the effective time of the merger; and

         Certain Other Covenants. The merger agreement contains additional mutual covenants, which include, among other things, agreements by each party to:

    • absence of any law, rule, order, injunction or judgment enacted or deemed applicable to the merger that would reasonably be expected to (1) materially and adversely diminish the benefits expected to be derived by the parties on the date of the merger agreement from the combination of CVS and Caremark via the merger (the combined business to be taken as a whole), in such a manner that either CVS or Caremark would not have entered into the merger agreement in the face of such materially and adversely diminished benefits, or (2) otherwise have a material adverse effect after the effective time of the merger on CVS/Caremark and its subsidiaries, taken as a whole;

         Right to Terminate. The merger agreement may be terminated at any time before the effective time of the merger in any of the following ways:

    (a) by mutual written consent of CVS and Caremark;
         
    (b) by either CVS or Caremark if:
         
     
  • the merger has not been completed by November 1, 2007 (or May 1, 2008 if the reason for not closing by November 1, 2007 is that the waiting period applicable to the merger under the HSR Act has not expired or been terminated and this is the only reason for failure to complete the merger);
         
     
  • there is a permanent legal prohibition to completing the merger;

    (c) by CVS, if:
         
     
  • the Caremark board of directors has made a change in recommendation; or
         
     
  • Caremark (or any officer, director, banker or counsel of Caremark) has willfully and materially breached its covenant not to solicit any acquisition proposal as described under “—Certain Covenants—No Solicitation” beginning on page 110 or its covenant to use all commercially reasonable efforts to hold a meeting of its stockholders to vote on the merger agreement and merger;

         If the merger agreement is validly terminated, the agreement will become void without any liability on the part of any party unless the party is in willful breach of its obligations. However, the provisions of the merger agreement

    116

         Except as described above (and subject to an exception relating to the payment of (1) filing fees due in connection with filings required under the HSR Act or (2) fees and expenses incurred in respect of the printing, filing and mailing of this document, each of which will be shared equally by the parties), all costs and expenses incurred in connection with the merger agreement, the merger and the other related transactions, will be paid by the party incurring such costs or expenses.

    Amendments; Waivers

However, after the stockholders of either CVS or Caremark have approved the applicable proposals set forth in this document, any amendment that requires stockholder approval may not be made without that approval.

    THE CVS SPECIAL MEETING

         The CVS board of directors is using this document to solicit proxies from stockholders of CVS who hold shares of CVS common stock and CVS ESOP preference stock on the CVS record date for use at the special meeting of CVS stockholders. CVS is first mailing this proxy statement/prospectus and accompanying form of proxy to CVS stockholders on or about [], 2007.

    Date, Time and Place

         The special meeting of CVS stockholders will be held at CVS’ corporate headquarters, One CVS Drive, Woonsocket, Rhode Island 02895 at 11:00 a.m., Eastern Time, on February 23, 2007.

    Purpose of the CVS Special Meeting

         At the CVS special meeting, CVS stockholders will be asked to consider and vote upon the following proposals:

      1. to approve the amendments of the CVS charter, effective upon completion of the merger, to increase the authorized number of shares of CVS common stock from 1 billion shares to 3.2 billion shares and to change the name of CVS Corporation to “CVS/Caremark Corporation” as described in “CVS Charter Amendment” beginning on page 127;
         
      2. to approve the issuance of shares of CVS/Caremark common stock to Caremark stockholders on the terms and subject to the conditions of the merger agreement as described in “The Merger Agreement—Structure of the Merger” beginning on page 106; and
         
      3. if submitted to a vote of the CVS stockholders, to approve any adjournment or postponement of the CVS special meeting to another time and/or place for the purpose of soliciting additional proxies in favor of the foregoing proposals if there are not sufficient votes to effect either of the foregoing proposals.

    Board Recommendations

         The CVS board of directors has unanimously determined that the merger agreement and the transactions contemplated by it, including the merger, are advisable and in the best interests of CVS and its stockholders and unanimously recommends that the CVS stockholders vote “FOR” the proposals to amend the CVS charter and to issue shares of CVS/Caremark common stock to Caremark stockholders in the merger and “FOR” the proposal to approve the adjournment or postponement, including if necessary, in order to solicit additional proxies in favor of the foregoing proposals.

    CVS Record Date; Shares Entitled to Vote

         The CVS board of directors has fixed the close of business on January 19, 2007 as the record date, referred to as the CVS record date, for CVS stockholders entitled to notice of and to vote at the CVS special meeting of CVS stockholders or any adjournment or postponement of the CVS special meeting. The special meeting of CVS stockholders is referred to as the CVS special meeting.

         The only outstanding voting securities of CVS are the shares of CVS common stock and CVS ESOP preference stock. Only holders of record of the shares of CVS Common Stock and CVS ESOP preference stock on the CVS record date are entitled to notice of and to vote at the CVS special meeting. Under Delaware law and the CVS charter, each share of CVS common stock is entitled to one vote on all matters submitted to CVS stockholders. Under the CVS charter, the holders of CVS ESOP preference stock are entitled to vote on all matters submitted to a vote of holders of CVS common stock, voting together with the CVS common stock as a single class. Each share of CVS ESOP preference stock is entitled to the number of votes equal to the number of shares of CVS common stock into which such share of CVS ESOP preference stock is entitled to be converted on the CVS record date, rounded up to the nearest tenth of a share, for the CVS special meeting (which is currently 4.6 votes, subject to adjustment in the case of certain dilutive events). Each participant in the CVS Plan instructs the trustee of the CVS Plan how to vote his or her shares of (i) CVS ESOP preference stock and (ii) CVS common stock held in the CVS Plan. Unallocated

    118






    shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan and shares of CVS ESOP preference stock and CVS common stock held in the CVS Plan with respect to which the trustee of the CVS Plan receives no timely voting instructions will be voted by the trustee of the CVS Plan in the same proportion as it votes all the shares as to which it has received timely voting instructions.

         On the CVS record date, there were approximately 826,911,756 outstanding shares of CVS common stock entitled to vote at the CVS special meeting. On the CVS record date, there were approximately 3,990,277 outstanding shares of CVS ESOP preference stock entitled to vote at the CVS special meeting, representing approximately 18,355,274 votes in the aggregate, voting with the CVS common stock as a single class.

         Based on the number of shares of CVS ESOP preference stock and CVS common stock outstanding as of the CVS record date, holders of CVS ESOP preference stock will be entitled to approximately 18,355,274 votes in the aggregate at the CVS special meeting, representing approximately 2.17% of the voting power of the CVS common stock and CVS ESOP preference stock, voting as a single class, as of such date. See “Description of CVS Capital Stock—CVS Preferred Stock and Preference Stock” beginning on page 131.

         Shares of CVS common stock held by CVS as treasury shares and shares of CVS common stock held by its subsidiaries will not be entitled to vote.

         Votes are exercisable in person, through the Internet, by telephone or by properly executed and delivered proxy with respect to the CVS special meeting as described in “—Voting of Proxies” beginning on page 120.

    Quorum Requirement

         Under Delaware law and the CVS bylaws, a quorum of CVS stockholders at the special meeting is necessary to transact business at the special meeting of the CVS stockholders. The presence of holders representing at least a majority of the votes of all outstanding CVS common stock and CVS ESOP preference stock entitled to vote at the CVS special meeting, whether present in person or by properly executed and delivered proxy, will constitute a quorum for the transaction of business at the CVS special meeting. Broker non-votes and abstentions will not be counted for purposes of satisfying the applicable quorum requirement with respect to the proposal to issue shares of CVS/Caremark in the merger (Proposal 2, below). For purposes of that proposal only, the number of votes cast must represent a majority of the number of votes represented by all outstanding shares of CVS common stock and CVS ESOP preference stock, voting together as a single class.

         All shares of CVS common stock and CVS ESOP preference stock represented in person or by proxy at the CVS special meeting, except in the case of Proposal 2, including abstentions and broker non-votes (as defined below) will be treated as present for purposes of determining the presence or absence of a quorum for all matters for consideration at the CVS special meeting.

         Under NYSE rules, brokers who hold shares in street name for customers have the authority to vote on certain “routine” proposals when they have not received instructions from beneficial owners. Under NYSE rules, such brokers are precluded from exercising their voting discretion with respect to the approval and adoption of non-routine matters, such as the merger, the amendments to the CVS charter and the issuance of shares of CVS/Caremark common stock in the merger and thus precluded from exercising their voting discretion with respect to the proposal to adjourn or postpone the CVS special meeting. Therefore, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote such shares with respect to the approval of the proposals to amend the CVS charter or to issue shares of CVS/Caremark in the merger. By signing your proxy card and returning it to your broker without specific instruction as to any proposal, your shares represented by that proxy will be voted in favor of that proposal. Any shares you beneficially own not identified as represented by that proxy will be considered a broker non-vote.

    Stock Ownership of CVS Executive Officers and Directors

         On January 19, the CVS record date, executive officers and directors of CVS and their affiliates beneficially owned and were entitled to vote approximately 1,181,972 shares of CVS common stock and approximately 6,125

    119






    shares of CVS ESOP preference stock (excluding exercisable options). These shares represent approximately 0.14% of the aggregate voting power of CVS shares entitled to vote at the special meeting.

    Votes Required to Approve CVS Proposals

         Each of the CVS proposals to be considered at the CVS special meeting requires the vote percentage described below. You may vote for or against any or all of the proposals submitted at the CVS special meeting or abstain from voting.

     

    Required Vote for CVS Charter Amendment (Proposal 1)

         The affirmative vote of at least a majority of the votes represented by the outstanding CVS common stock and CVS ESOP preference stock entitled to vote at the CVS special meeting, voting together as a single class, is required to approve the amendments to the CVS charter. Consequently, an abstention from voting or a broker non-vote on Proposal 1 will have the effect of a vote against Proposal 1.

     

    Required Vote for Issuance of CVS/Caremark Common Stock in the Merger (Proposal 2)

         The approval of the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger requires the affirmative vote of holders of shares representing at least a majority of the votes represented by shares of CVS common stock and CVS ESOP preference stock, voting together as a single class, casting votes at the CVS special meeting. Additionally, assuming a quorum is present, an abstention or a failure to vote, including broker non-votes, will have no effect in determining whether the issuance of shares of CVS/Caremark common stock in the merger will be approved.

     

    Required Vote for Adjournment or Postponement of the CVS Special Meeting (Proposal 3)

         The approval of any adjournment or postponement of the CVS special meeting, including if necessary, to solicit additional proxies if there are not sufficient votes for each of the foregoing proposals requires the affirmative vote of holders of CVS common stock and CVS ESOP preference stock, voting together as a single class, representing a majority of the voting power of such shares present in person or represented by proxy at the CVS special meeting and entitled to vote on the proposal.

         An abstention will have the same effect as a vote against the proposal. A broker non-vote will have no effect on the vote.

         Each of Proposal 1 and Proposal 2 are conditioned upon the other and the approval of each such proposal is a condition to the completion of the merger. Neither the issuance of CVS/Caremark common stock in connection with the merger nor the amendments of the CVS charter will take place or be effective unless both of these proposals are approved by the CVS stockholders and the merger is completed. Therefore, the completion of the merger cannot proceed without the approval of both Proposal 1 and Proposal 2.

         Independent inspectors count the votes on each proposal to be voted upon at the CVS special meeting. Your individual vote is kept confidential from CVS and Caremark, unless special circumstances exist. For example, a copy of your proxy card will be sent to CVS if you write comments on the card.

    Voting of Proxies

     

    By Mail

         A proxy card is enclosed for your use. To submit your proxy by mail, CVS asks that you complete and sign the accompanying proxy and, if you are a stockholder of record, return it to The Bank of New York as soon as possible in the enclosed postage-paid envelope or pursuant to the instructions set out in the proxy card. If you are a beneficial owner, please refer to your proxy card or the information provided to you by your bank, broker, custodian or record holder. When the accompanying proxy is returned properly executed, the shares of CVS common stock or

    120






    CVS ESOP preference stock represented by it will be voted at the CVS special meeting in accordance with the instructions contained in the proxy.

         If proxies are returned properly executed without indication as to how to vote, the CVS common stock and CVS ESOP preference stock represented by each such proxy will be considered to be voted in favor of all matters for consideration at the CVS special meeting as follows: 1) “FOR” the proposal to amend the CVS charter, 2) “FOR” the proposal to approve the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger and 3) “FOR” the proposal to adjourn or postpone the special meeting, including if necessary, to permit further solicitation of the proxies on the foregoing proposals.

         Your vote is important. Accordingly, please sign, date and return the enclosed proxy card whether or not you plan to attend the CVS special meeting in person.

      By Telephone

         If you are a stockholder of record, you may also submit your proxy by telephone by dialing the toll-free telephone number on your proxy card and providing the unique control number indicated on the enclosed card. Telephone voting is available 24 hours a day and will be accessible until 11:59 p.m. on February 22, 2007. Easy-to-follow voice prompts allow you to submit your proxy and confirm that your instructions have been properly recorded. If you are a beneficial owner, please refer to your proxy card or the information provided by your bank, broker, custodian or record holder for information on telephone voting. If you are located outside the United States, Canada and Puerto Rico, see your proxy card or other materials for additional instructions. If you submit your proxy by telephone, you do not need to return your proxy card. If you hold shares through a broker or other custodian, please check the voting form used by that firm to see if it offers telephone voting.

      By Internet

         If you are a stockholder of record, you may also choose to submit your proxy on the Internet. The website for Internet voting and the unique control number you will be required to provide are on your proxy card. Internet voting is available 24 hours a day, and will be accessible until 11:59 p.m. on February 22, 2007. If you are a beneficial owner, please refer to your proxy card or the information provided by your bank, broker, custodian or record holder for information on Internet voting. As with telephone voting, you will be given the opportunity to confirm that your instructions have been properly recorded. If you submit your proxy on the Internet, you do not need to return your proxy card. If you hold shares through a broker or other custodian, please check the voting form used by that firm to see if it offers Internet voting.

      Voting In Person

         If you wish to vote in person at the CVS special meeting, a ballot will be provided at the CVS special meeting. However, if your shares are held in the name of your bank, broker, custodian or other record holder, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the meeting.

    Revocation of Proxies

         You have the power to revoke your proxy at any time before your proxy is voted at the CVS special meeting. If you grant a proxy in respect of your CVS shares and then attend the CVS special meeting in person, your attendance at the special meeting or at any adjournment or postponement of the special meeting will not automatically revoke your proxy. Your proxy can be revoked in one of four ways:

    • you can send a signed notice of revocation;

    • you can grant a new, valid proxy bearing a later date (including, if applicable, a proxy by telephone or through the Internet);

    • you can revoke the proxy in accordance with the telephone or Internet voting procedures described in the proxy voting instructions attached to the proxy card; or

    121






    • you can attend the special meeting (or, if the special meeting is adjourned or postponed, attend the adjourned or postponed meeting) and vote in person which will automatically cancel any proxy previously given, but your attendance alone will not revoke any proxy previously given.

         If you choose either of the first two methods, you must submit your notice of revocation or new proxy to CVS’ Corporate Secretary no later than the beginning of the CVS special meeting or, if the special meeting is adjourned or postponed, before the adjourned or postponed meeting is actually held.

         If your shares are held in the name of a broker or nominee, you may change your vote by submitting new voting instructions to your broker or nominee. If you need assistance in changing or revoking your proxy, please contact Morrow & Co., Inc., 470 West Avenue, Stamford, CT 06902, toll-free at 800-245-1502.

    Solicitation of Proxies

         This solicitation is made on behalf of the CVS board of directors and CVS will pay the costs of soliciting and obtaining proxies, including the cost of reimbursing banks and brokers for forwarding proxy materials to their principals. Proxies may be solicited, without extra compensation, by CVS’ officers and employees by mail, telephone, fax, personal interviews or other methods of communication. CVS has engaged Morrow & Co., Inc. to assist it in the distribution and solicitation of proxies at a fee of $75,000, plus expenses. CVS and Caremark will also reimburse brokers and other custodians, nominees and fiduciaries for their expenses in sending these materials to you and getting your voting instructions.

          Do not send any stock certificates with your proxy cards.

    Householding

         Under SEC rules, a single set of annual reports and proxy statements may be sent to any household at which two or more CVS stockholders reside if they appear to be members of the same family. Each CVS stockholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information CVS stockholders receive and reduces mailing and printing expenses for CVS. Brokers with accountholders who are CVS stockholders may be householding CVS’ proxy materials. As indicated in the notice previously provided by these brokers to CVS stockholders, a single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from an affected CVS stockholder. Once you have received notice from your broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement, please notify your broker. CVS stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker.

         Under Delaware law and the Caremark bylaws, a quorum of Caremark stockholders at the special meeting is necessary to transact business at the special meeting of the Caremark stockholders. The presence of holders of at least a majority of Caremark common stock outstanding on the Caremark record date and entitled to vote, whether present in person or by properly executed and delivered proxy, will constitute a quorum for the transaction of business at the Caremark special meeting.

         All shares of Caremark common stock represented at the Caremark special meeting but not voting, including abstentions and broker non-votes, will be treated as present for purposes of determining the presence or absence of a quorum for all matters for consideration at the Caremark special meeting.

    123






         Under NYSE rules, brokers who hold shares in street name for customers have the authority to vote on certain “routine” proposals when they have not received instructions from beneficial owners. Under NYSE rules, such brokers are precluded from exercising their voting discretion with respect to the approval and adoption of non-routine matters such as the merger, and thus precluded from exercising their voting discretion with respect to the proposal to adjourn or postpone the Caremark special meeting. Therefore, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote such shares with respect to the adoption of the merger agreement and approval of the merger. By signing your proxy card and returning it to your broker without specific instruction as to any proposal, your shares represented by that proxy will be voted in favor of that proposal. Any shares you beneficially own not identified as represented by that proxy will be considered a broker non-vote.

    Stock Ownership of Caremark Executive Officers and Directors

         On January 15, 2007 the Caremark record date, executive officers and directors of Caremark and their affiliates owned and were entitled to vote 449,201 shares of Caremark common stock, or less than 1% of the aggregate voting power of Caremark common stock entitled to vote at the Caremark special meeting.

    Votes Required to Approve Caremark Proposals

     

    Required Vote for Adoption of Merger Agreement and Approval of Merger (Proposal 1)

         The affirmative vote of holders of at least a majority of the outstanding shares of Caremark common stock entitled to vote is required to adopt the merger agreement and to approve the merger. Consequently, an abstention from voting or a broker non-vote on Proposal 1 will have the effect of a vote against Proposal 1.

     

    Required Vote for Adjournment or Postponement of the Caremark Special Meeting (Proposal 2)

         The approval of any adjournment or postponement of the Caremark special meeting, including if necessary, to solicit additional proxies if there are not sufficient votes for the foregoing proposal, requires the affirmative vote of holders of Caremark common stock representing at least a majority of shares entitled to vote at the Caremark special meeting present in person or by proxy at the meeting and entitled to vote on the proposal.

         An abstention will have the same effect as a vote against the proposal. A broker non-vote will have no effect on the vote.

         Adoption of the merger agreement and approval of the merger by the requisite vote of the Caremark stockholders is required to complete the merger.

         Independent inspectors count the votes on each proposal to be voted upon at the Caremark special meeting. Your individual vote is kept confidential from CVS and Caremark, unless special circumstances exist. For example, a copy of your proxy card will be sent to Caremark if you write comments on the card.

    Voting of Proxies

     

    By Mail

         A WHITE proxy card is enclosed for your use. To submit your proxy by mail, Caremark asks that you sign and date the accompanying proxy and, if you are a stockholder of record, return it to Caremark as soon as possible in the enclosed postage-paid envelope or pursuant to the instructions provided in the proxy card. If the envelope is missing, please see the instructions on your proxy card. If you are a beneficial owner, please refer to your WHITE proxy card or the information provided to you by your bank, broker, custodian or record holder. When the accompanying WHITE proxy is returned properly executed, the shares of Caremark common stock represented by it will be voted at the Caremark special meeting in accordance with the instructions contained in the proxy.

         If WHITE proxies are returned properly executed without indication as to how to vote, the Caremark common stock represented by each such proxy will be considered to be voted in favor of all matters for consideration at the Caremark special meeting as follows: (1) “FOR” the proposal to adopt the merger agreement and to approve the

    124






    merger and (2) “FOR” the proposal to adjourn or postpone the special meeting, including if necessary, to permit further solicitation of the proxies on the foregoing proposal.

         There are no voting agreements in place in respect of any outstanding shares of Caremark common stock entitled to vote at the Caremark special meeting.

         Your vote is important. Accordingly, please sign, date and return the enclosed proxy card whether or not you plan to attend the Caremark special meeting in person.

      By Telephone

         If you are a stockholder of record, you may also submit your proxy by telephone by dialing the toll-free telephone number on your WHITE proxy card and providing the unique control number indicated on the enclosed WHITE proxy card. Telephone voting is available 24 hours a day. Easy-to-follow voice prompts allow you to submit your proxy and confirm that your instructions have been properly recorded. If you are a beneficial owner, please refer to your WHITE proxy card or the information provided by your bank, broker, custodian or record holder for information on telephone voting. If you are located outside the United States, Canada and Puerto Rico, see your proxy card or other materials for additional instructions. If you hold shares through a broker or other custodian, please check the voting form used by that firm to see if it offers telephone or Internet voting.

      By Internet

         If you are a stockholder of record, you may also choose to submit your proxy on the Internet. Please refer to the enclosed WHITE proxy card for the website for Internet voting and the unique control number you will be required to provide. Internet voting is available 24 hours a day. If you are a beneficial owner, please refer to your proxy card or the information provided by your bank, broker, custodian or record holder for information on Internet voting. As with telephone voting, you will be given the opportunity to confirm that your instructions have been properly recorded. If you hold shares through a broker or other custodian, please check the voting form used by that firm to see if it offers Internet voting.

      Voting In Person

         If you wish to vote in person at the Caremark special meeting, a ballot will be provided at the Caremark special meeting. However, if your shares are held in the name of your bank, broker, custodian or other record holder, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the meeting.

    Revocation of Proxies

         You have the power to revoke your proxy at any time before your proxy is voted at the Caremark special meeting. If you grant a proxy in respect of your Caremark shares and then attend the Caremark special meeting in person, your attendance at the special meeting or at any adjournment or postponement of the special meeting will not automatically revoke your proxy. Your proxy can be revoked in one of four ways:

    • you can send a signed notice of revocation;

    • you can grant a new, valid proxy bearing a later date (including, if applicable, a proxy by telephone or through the Internet);

    • you can revoke the proxy in accordance with the telephone or Internet voting procedures described in the proxy voting instructions attached to the proxy card; or

    • you can attend the special meeting (or, if the special meeting is adjourned or postponed attend the adjourned or postponed meeting) and vote in person, which will automatically cancel any proxy previously given, or you may revoke your proxy in person, but your attendance alone will not revoke any proxy previously given.

    125






         If you choose either of the first two methods, you must submit your notice of revocation or new proxy to Caremark’s Corporate Secretary no later than the beginning of the Caremark special meeting or, if the special meeting is adjourned or postponed, before the adjourned or postponed meeting is actually held.

         If your shares are held in the name of a broker or nominee, you may change your vote by submitting new voting instructions to your broker or nominee. If you need assistance in changing or revoking your proxy, please contact Innisfree M&A Incorporated toll free at (877) 750-9498 (stockholders) or collect at (212) 750-5833 (banks and brokers).

    Solicitation of Proxies

         This solicitation is made on behalf of the Caremark board of directors and Caremark will pay the costs of soliciting and obtaining proxies, including the cost of reimbursing banks and brokers for forwarding proxy materials to their principals. Proxies may be solicited, without extra compensation, by Caremark’s officers and employees by mail, telephone, fax, personal interviews or other methods of communication. Caremark has engaged Innisfree M&A Incorporated to assist it in the distribution and solicitation of proxies at a fee of $75,000, plus discretionary fee to be negotiated and expenses. CVS and Caremark will also reimburse brokers and other custodians, nominees and fiduciaries for their expenses in sending these materials to you and getting your vote.

         Do not send any stock certificates with your proxy cards. If the merger is approved by Caremark stockholders at the Caremark special meeting, and approval of the amendments of the CVS charter and the issuance of shares of CVS/Caremark common stock to Caremark stockholders in the merger are each approved by CVS stockholders at the CVS special meeting, the exchange agent will mail transmittal forms with instructions for the surrender of stock certificates for shares of Caremark common stock as soon as practicable after completion of the merger.

    Householding

         Under SEC rules, a single set of annual reports and proxy statements may be sent to any household at which two or more Caremark stockholders reside if they appear to be members of the same family. Each Caremark stockholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information Caremark stockholders receive and reduces mailing and printing expenses for Caremark. Brokers with accountholders who are Caremark stockholders may be householding Caremark’s proxy materials. As indicated in the notice previously provided by these brokers to Caremark stockholders, a single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from an affected Caremark stockholder. Once you have received notice from your broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement, please notify your broker. Caremark stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker.

    CVS CHARTER AMENDMENT

         At the CVS special meeting, CVS stockholders will be asked to approve the amendments (described below) of CVS’ Amended and Restated Certificate of Incorporation, which is referred to as the CVS charter. The amendments will increase the number of authorized shares of CVS common stock from 1 billion shares to 3.2 billion shares and will change the name of CVS Corporation to CVS/Caremark Corporation. As a condition to the completion of the merger, the CVS stockholders must approve the amendments to the CVS charter described in this section. Annex B to this document contains the complete text of the proposed amendments to the CVS charter, which you are urged to read in its entirety. The CVS charter, as amended by the proposed amendments, is referred to as the amended CVS charter. If the merger is not completed for any reason, the amendments described in this section will be of no force and effect.

    Increase of Authorized Common Stock

         Under the CVS charter, one billion shares of common stock are currently authorized. On January 19, 2007, the CVS record date, approximately 826,911,756 shares of CVS common stock were issued and outstanding (not counting shares held in CVS’ treasury).

         To complete the merger, CVS expects that approximately 712.4 million shares of CVS/Caremark common stock will be required to be issued to holders of shares of Caremark common stock based on the number of shares of Caremark common stock outstanding as of January 15, 2007 and that approximately 33.5 million shares of CVS/Caremark common stock will be required to be reserved for issuance under Caremark options and warrants.

         Accordingly, the shares of CVS common stock currently authorized under the CVS charter will not be sufficient to complete the merger. CVS therefore asks CVS stockholders to approve the proposed amendment, which will change Article FOURTH of the CVS charter to increase the number of authorized shares of CVS common stock from 1 billion to 3.2 billion shares.

         The increased number of authorized shares will give CVS sufficient shares to complete the merger. At present, CVS has no plans to issue shares for any other purpose. CVS believes, however, that it is desirable to have additional shares available for other corporate purposes that might arise in the future. For example, such shares could also be used for acquisitions or to raise capital. Under some circumstances, it is also possible to use unissued shares for anti-takeover purposes, but CVS has no present intention to take this action.

         Whether any future issuance of shares unrelated to the merger would be submitted for stockholder vote depends upon the nature of the issuance, legal and stock exchange requirements and the judgment of the board of directors of the combined company at the time.

    Name Change

         The merger agreement provides that, when the merger takes effect, CVS’ name will be changed from CVS Corporation to CVS/Caremark Corporation. The proposed amendment implements this name change by amending Article FIRST of the CVS charter.

    127






    CVS BYLAWS AMENDMENT

         In connection with entering into the merger agreement, the CVS board of directors approved an amendment to CVS’ current bylaws, which is referred to as the CVS bylaws. The changes to the CVS bylaws will become effective no later than, but only upon, the effective time of the merger. If the merger is not completed for any reason, the amendments described in this section will be of no force and effect. The following discussion describes the material changes to the CVS bylaws and is qualified in its entirety by reference to Annex C, which contains the complete text of the CVS bylaws that will take effect on completion of the merger agreement. The amended and restated bylaws set forth in Annex C to this document is referred to as the amended CVS bylaws.

    Corporate Governance

         Board Composition. The amended CVS bylaws will provide that at the effective time of the merger the CVS/Caremark board of directors will be comprised of a number of directors to be agreed on by CVS and Caremark, with an equal number of directors to be designated by each of Caremark and CVS.

         Each of the directors on the CVS/Caremark board of directors designated by CVS, who are referred to as the CVS-designated directors, and each of the directors on the CVS/Caremark board of directors designated by Caremark, who are referred to as Caremark-designated directors, will hold office until the first annual meeting of CVS/Caremark stockholders after the effective time of the merger, which is referred to as the first annual meeting. Before the first annual meeting, a CVS-designated director may only be removed by a majority vote of the other CVS-designated directors and any vacancy on the CVS/Caremark board of directors resulting from the death, removal or resignation of a CVS-designated director may only be filled by the remaining CVS-designated directors. Similarly, before the first annual meeting, a Caremark-designated director may only be removed by a majority vote of the other Caremark-designated directors, and any vacancy on the CVS/Caremark board of directors resulting from the death, removal or resignation of a Caremark-designated director may only be filled by the remaining Caremark-designated directors.

         Committee Composition. The amended CVS/Caremark bylaws also provide that at the effective time of the merger, the chairman of the CVS/Caremark audit committee will be designated by the Caremark-designated directors, and the chairman of each of the CVS/Caremark management, planning and development committee and nominating and corporate governance committee will be designated by the CVS-designated directors. In addition, as of the effective time of the merger, the executive committee of CVS/Caremark’s board of directors will consist of Thomas M. Ryan, E. Mac Crawford, one member appointed by the CVS-designated directors and one member appointed by the Caremark-designated directors.

         Commencing with the first annual meeting, the composition of the CVS/Caremark board of directors and the composition of the aforementioned committees will be determined by normal process as set forth in the amended CVS bylaws.

    Chairman of the Board

         The amended CVS bylaws also provide that, as of the effective time of the merger, E. Mac Crawford, the current chairman, president and chief executive officer of Caremark, will be the chairman of the CVS/Caremark board of directors. As long as Mr. Crawford is the chairman of the CVS/Caremark board of directors, the CVS/Caremark board of directors is prohibited from appointing a co-chairman.

    Chief Executive Officer

         The amended CVS bylaws also provide that, as of the effective time of the merger, Thomas M. Ryan will be the chief executive officer of CVS/Caremark. The amended CVS bylaws further provide that any removal of Thomas M. Ryan as chief executive officer of CVS/Caremark before January 2010 will require the approval of three-quarters of the members of the CVS/Caremark board of directors.

    128






    Headquarters

         The amended CVS bylaws also provide that, as of the effective time of the merger, the headquarters of CVS/Caremark’s pharmacy services business will be located in Nashville, Tennessee. Any decision by the CVS/Caremark board of directors to change the headquarters of the pharmacy services business of the combined company prior to the third anniversary of the effective time of the merger will require the approval of three-quarters of the members of the CVS/Caremark board of directors.

    Other Changes to Bylaws

         Board Quorum. Under the amended CVS bylaws, a majority of the directors on the CVS/Caremark board of directors will constitute a quorum of directors for the transaction of business. The current CVS bylaws define a quorum as one-third of the total number of the directors on the CVS board of directors.

         Corporate Name Change. The amended CVS bylaws also provide that any change in the name of the combined company from “CVS/Caremark Corporation” will require the approval of three-quarters of the members of the CVS/Caremark board of directors.

    Amendments

         Under the amended CVS bylaws, the approval of three-quarters of the members of the CVS/Caremark board of directors will be required in order to amend the amended CVS bylaws in a way that will change any of the following:

    • the provisions described under “—Corporate Governance” or “—Headquarters” above;

    • the provision relating to the removal of Thomas M. Ryan as chief executive officer of CVS/Caremark described under “—Chief Executive Officer” above; or

    • the provision restricting any future name change of CVS/Caremark described under “—Other Changes to Bylaws—Corporate Name Change” above.

    DESCRIPTION OF CVS CAPITAL STOCK

         The following summary of the material terms of the capital stock of CVS is not intended to be a complete summary of all the rights and preferences of CVS’ capital stock. CVS and Caremark urge you to read the CVS charter, the CVS bylaws, the amended CVS charter and the amended CVS bylaws in their entirety, and refer to the applicable provisions of Delaware law, for a complete description of the rights and preferences of CVS’ capital stock. Copies of the CVS charter and CVS bylaws will be sent to holders of shares of CVS common stock, CVS ESOP preference stock or Caremark common stock upon request. See “Where You Can Find More Information” beginning on page 158. The proposed amendments of the CVS charter are described in “CVS Charter Amendment” beginning on page 127 and the full text of the amendment of the CVS charter is attached as Annex B to this document. The proposed amended CVS bylaws are described in “CVS Bylaws Amendment” beginning on page 128 and the full text of the amended CVS bylaws is attached as Annex C to this document.

    Authorized Capital Stock

         Before the Merger. Under the CVS charter, CVS’ authorized capital stock consists of one billion shares of CVS common stock, $0.01 par value, 120,619 shares of cumulative preferred stock, $0.01 par value, and 50 million shares of preference stock, $1.00 par value. The CVS cumulative preferred stock and CVS preference stock are sometimes referred to as CVS preferred stock. At January 19, 2007, the CVS record date, there were issued and outstanding:

    • approximately 826,911,756 shares of CVS common stock (not counting shares held in CVS’ treasury);

    • employee stock options to purchase an aggregate of approximately 41,210,326 shares of CVS common stock; and

    • approximately 3,990,277 shares of CVS ESOP preference stock.

         After the Merger. If the merger is completed, the CVS charter will be amended to increase the authorized number of shares of CVS/Caremark common stock to 3.2 billion. See “CVS Charter Amendment” beginning on page 127.

    CVS Common Stock

         CVS Common Stock Outstanding. The outstanding shares of CVS common stock are, and the shares of CVS/Caremark common stock issued pursuant to the merger will be, duly authorized, validly issued, fully paid and nonassessable.

         Voting Rights. Each holder of a share of CVS common stock is entitled to one vote for each share held of record on the applicable record date on all matters submitted to a vote of stockholders. See “Comparison of Stockholder Rights” beginning on page 133 for additional information on CVS voting rights.

         Dividend Rights. Subject to any preferential dividend rights granted to the holders of any shares of CVS preferred stock that may at the time be outstanding, holders of shares of CVS common stock are entitled to receive such dividends as may be declared from time to time by the CVS board of directors out of funds legally available therefor. Under the CVS charter, no dividends may be declared, paid, or set aside for payment on shares of CVS common stock unless full cumulative dividends are paid on the outstanding CVS ESOP preference stock and any other CVS preferred stock issued and outstanding at such time that is designated to have such dividend preference.

         Rights Upon Liquidation. In the event of liquidation, holders of shares of CVS common stock are entitled to share pro rata in all remaining assets available for distribution to stockholders after payment or providing for CVS’ liabilities and the liquidation preference of the outstanding CVS ESOP preference stock and any other CVS preferred stock issued and outstanding at such time. See “—CVS Preferred Stock and Preference Stock—Rights Upon Liquidation” beginning on page 131 for a description of the liquidation preference of CVS ESOP preference stock.

    130






         Preemptive Rights. Holders of shares of CVS common stock have no preemptive right to purchase, subscribe for or otherwise acquire any unissued or treasury shares or other securities.

    CVS Preferred Stock and Preference Stock

         Outstanding CVS Preferred Stock. As of January 19, 2007, the CVS record date, approximately 3,990,277 shares of CVS Series One Preference Stock, which is referred to as CVS ESOP preference stock, were issued and outstanding. No other shares of CVS preferred stock are issued or outstanding.

         Voting Rights. Each share of CVS ESOP preference stock is entitled to vote on all matters submitted to a vote of CVS common stock, voting together as a single class with the holders of CVS common stock. Each share of CVS ESOP preference stock is entitled to the number of votes equal to the number of shares of CVS common stock into which such share of CVS ESOP preference stock could be converted on the record date, rounded up to the nearest tenth of a share, for the applicable meeting. See “—Redemption at the Option of CVS and Under Certain Circumstances and Conversion Rights of Holders” below for the current conversion rate.

         Dividend Rights. Pursuant to the applicable provisions of the CVS charter, holders of CVS ESOP preference stock are entitled to receive when, as and if declared by the CVS board of directors, out of funds legally available for payment, cash dividends at the rate per annum equal to the greater of (x) the result of a formula based on historical CVS common stock dividend payments and the number of shares of CVS common stock into which CVS ESOP preference stock may be converted on the dividend record date and (y) $3.90. Dividends are cumulative without interest. In the event that full cumulative dividends on the CVS ESOP preference stock have not been declared and paid or set apart for payment when due, no dividends may be paid or distributions made on, and no payment may be made on account of purchase, redemption or other retirement of, CVS common stock or any other class of stock ranking junior to CVS ESOP preference stock until full cumulative dividends on the CVS ESOP preference stock have been paid or declared and provided for.

         Rights Upon Liquidation. Under the CVS charter, holders of CVS ESOP preference stock are entitled to liquidating distributions in the amount of $53.45 per share, plus an amount equal to all accrued and unpaid dividends on such shares to the date fixed for such distribution, before any amount will be paid or distributed to holders of common stock. Holders of CVS ESOP preference stock are not entitled to any distributions upon liquidation in excess of this amount.

         Redemption at the Option of CVS and Under Certain Circumstances and Conversion Rights of Holders. Shares of CVS ESOP preference stock may be redeemed at the option of CVS, in whole or in part, at any time or from time to time, out of funds legally available therefor, and under certain limited circumstances must be redeemed, at $53.45 per share plus an amount equal to accrued and unpaid dividends, if any, to the redemption date. Shares of CVS ESOP preference stock may be converted into CVS common stock at the option of holders at any time before the redemption date for such CVS ESOP preference stock into the number of shares of CVS common stock determined by dividing $53.45 for each share converted by the then-effective conversion price per share of common stock. Currently, one share of CVS ESOP preference stock may be converted into approximately 4.6 shares of CVS common stock (subject to adjustment in the case of certain dilutive events).

         Preemptive Rights. Holders of CVS ESOP preference stock have no preemptive rights to purchase, subscribe for or otherwise acquire any unissued or treasury shares or other securities.

         Blank Check Preferred Stock. Under the CVS charter, the CVS board of directors has the authority, without further stockholder approval but subject to certain limitations set forth in the CVS charter, to create one or more series of CVS preferred stock, to issue shares of CVS preferred stock in such series up to the maximum number of shares of the relevant class of CVS preferred stock authorized, and to determine the preferences, rights, privileges and restrictions of any series, including the dividend rights, voting rights, rights and terms of redemption, liquidating preferences, the number of shares constituting any such series and the designation of such series. Pursuant to this authority, the CVS board of directors could create and issue a series of preferred stock with rights, privileges or restrictions, and adopt a stockholder rights plan, having the effect of discriminating against an existing or prospective holder of such securities as a result of such security holder beneficially owning or commencing a tender

    131






    offer for a substantial amount of CVS common stock. One of the effects of authorized but unissued and unreserved shares of capital stock may be to render more difficult or discourage an attempt by a potential acquiror to obtain control of CVS by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of CVS’ management. The issuance of such shares of capital stock may have the effect of delaying, deferring or preventing a change in control of CVS without any further action by the stockholders of CVS. CVS has no present intention to adopt a stockholder rights plan, but could do so without stockholder approval at any future time.

    Transfer Agent and Registrar

    The Bank of New York is the transfer agent and registrar for the shares of CVS common stock.

    Stock Exchange Listing; Delisting and Deregistration of Caremark Common Stock

         It is a condition to the merger that the shares of CVS/Caremark common stock issuable in the merger be approved for listing on the NYSE on or before the effective time of the merger, subject to official notice of issuance. If the merger is completed, shares of Caremark common stock will cease to be listed on the NYSE.

    COMPARISON OF STOCKHOLDER RIGHTS

         CVS and Caremark are both incorporated under Delaware law. Any differences, therefore, in the rights of CVS stockholders and Caremark stockholders arise primarily from differences in their respective certificates of incorporation and bylaws. Upon completion of the merger, the certificate of incorporation and bylaws of CVS/Caremark will be identical in all respects to the CVS charter and CVS bylaws after giving effect to the proposed CVS charter amendments and CVS bylaw amendments contemplated by the merger agreement and described in “CVS Charter Amendment” and “CVS Bylaws Amendment” beginning on pages 127 and 128, respectively. Consequently, after the effective time of the merger, the rights of the former Caremark stockholders will be determined by reference to the amended CVS charter and amended CVS bylaws. The following table compares the material differences between the current rights of Caremark stockholders under the Caremark certificate of incorporation and bylaws, which are referred to as the Caremark charter and Caremark bylaws, respectively, and the current rights of CVS stockholders under the CVS charter and CVS bylaws, as well as the rights that those stockholders will have as CVS/Caremark stockholders under the amended CVS charter and amended CVS bylaws following the completion of the merger.

         Annexes B and C of this document contain the complete text of the proposed amendments of the CVS charter and the complete text of the amended CVS bylaws, respectively, that will, in each case, take effect as of the effective time of the merger. Copies of the CVS charter, the CVS bylaws, the Caremark charter and the Caremark bylaws will be sent to holders of CVS common stock, CVS ESOP preference stock or Caremark common stock upon request. See “Where You Can Find More Information” beginning on page 158. Because this summary does not provide a complete description of these documents, CVS and Caremark urge you to read each of their charters and bylaws as well as the amended CVS charter and the amended CVS bylaws in their entirety.

    Number of Directors   The Caremark bylaws provide that the number of directors will be not less than nine and not more than 18. The Caremark board of directors currently consists of 11 directors.  

    The CVS charter and CVS bylaws provide, and the amended CVS charter and amended CVS bylaws upon completion of the merger will provide, that the number of directors will not be less than three nor more than 18, as determined by action of the CVS board of directors.

    Before the merger. The CVS board of directors currently consists of 9 directors.

    After the merger. The amended CVS bylaws will provide that as of the effective time of the merger the CVS/Caremark board of directors will be composed of a number of directors to be agreed on by CVS and Caremark, with an equal number of directors to be designated by each of Caremark and CVS. See “CVS Bylaws Amendment—Corporate Governance” beginning on page 128 for a description of the composition of the CVS/Caremark board of directors as of the effective time of the merger.


    Classification of Board of Directors   The Caremark charter and Caremark bylaws provide for the division of the Caremark board of directors into three classes with staggered three-year terms, with each class to consist of as near to one-third of the total number of directors as possible. If the number of directors is changed, any increase or decrease will be apportioned among the three classes so as to maintain the number of directors in each class as nearly equal as possible.   CVS does not have, and CVS/Caremark, will not have upon completion of the merger, a classified board of directors.

    Removal of Directors   Under Delaware law, where there is a classified board of directors, any director may be removed only for cause, unless the corporation’s certificate of incorporation provides otherwise. The Caremark charter provides that a director may be removed from office for cause only and, subject to such removal, death, resignation, retirement or disqualification, will hold office until the annual meeting of Caremark’s stockholders for the year in which his term expires and until his successor is elected and qualified. As described below under “—Amendment of Certificate of Incorporation”, the Caremark charter further provides that no alteration, amendment or repeal of the foregoing provision will be effective to permit any director to be removed without cause unless the alteration, amendment or repeal has been approved by the holders of all shares of stock entitled to vote thereon.   Where a corporation does not have a classified board of directors, Delaware law provides that unless the corporation’s certificate of incorporation provides otherwise, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the votes then entitled to vote on the election of directors. The CVS charter does not contain, and the amended CVS charter upon completion of the merger will not contain, a provision with respect to the removal of directors. However, the amended CVS bylaws provide that prior to the first annual meeting of the combined company, a CVS-designated director may only be removed by a majority of the other CVS-designated directors and a Caremark-designated director may only be removed by a majority of the other Caremark-designated directors.
