ARTICLE 2

THE MERGER

Section 2.01. The Merger. (a) At the Effective Time, MergerSub shall be merged (the “Merger”) with and into Caremark in accordance with Delaware

Law, at which time the separate existence of MergerSub shall cease, and Caremark shall be the surviving corporation (the “Surviving Corporation”), and shall be a wholly owned, direct subsidiary of CVS.

(b) From and after the Effective Time, the Surviving Corporation shall possess all of the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of Caremark and MergerSub, all as provided under Delaware Law.

Section 2.02. Effective Time. As soon as practicable after satisfaction or, to the extent permitted under this Agreement, waiver of all conditions to the Merger set forth in Article 9 (excluding conditions that, by their nature, cannot be satisfied until the Closing), the parties shall file a certificate of merger (the “Certificate of Merger”) with the Delaware Secretary of State in such form as is required by and executed and completed in accordance with the relevant provisions of Delaware Law and make all other filings or recordings required by Delaware Law to effect the Merger. The Merger shall become effective at such time (the “Effective Time”) as the Certificate of Merger is duly filed with the Delaware Secretary of State (or at such later time as CVS and Caremark mutually agree and specify in the Certificate of Merger).

Section 2.03. Closing. Upon the terms and subject to the conditions set forth in Article 9, the closing of the Merger (the “Closing”) will take place as soon as practicable, but in no event later than five Business Days, after the satisfaction or waiver of the conditions (excluding conditions that, by their nature, cannot be satisfied until the Closing), or such other time and date that the parties agree to in writing. The Closing shall be held at the offices of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ unless another place is agreed to in writing by the parties hereto.

Section 2.04. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof;

(a) except as otherwise provided in Section 2.04(b), each share of Caremark Stock outstanding immediately prior to the Effective Time shall be cancelled and converted into the right to receive 1.670 (the “Exchange Ratio”) shares of CVS Stock (together with the cash in lieu of fractional shares of CVS Stock as specified below, the “Merger Consideration”);

(b) each share of Caremark Stock held by Caremark as treasury stock immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereof in accordance with this Article 2 and

(c) each share of common stock, par value $.001 per share, of MergerSub outstanding immediately prior to the Effective Time shall be converted into the right to receive one share of common stock, par value $.001 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 2.05. Surrender and Payment. (a) Prior to the Effective Time, CVS and Caremark shall appoint a mutually acceptable agent (the “Exchange Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing shares of Caremark Stock (the “Certificates”) or (ii) uncertificated shares of Caremark Stock (the “Uncertificated Shares”). CVS shall (x) deposit with the Exchange Agent, to be held in trust for the holders of Caremark Stock, certificates (if such shares shall be certificated) representing shares of CVS Stock issuable pursuant to Section 2.04 in exchange for outstanding shares of Caremark Stock and (y) make available to the Exchange Agent, as needed, cash in amounts that are sufficient to pay cash in lieu of fractional shares pursuant to Section 2.07 and any dividends or other distributions pursuant to Section 2.05(f), in each case, to be paid in respect of the Certificates and the Uncertificated Shares. Promptly after the Effective Time, CVS shall send, or shall cause the Exchange Agent to send, to each holder of shares of Caremark Stock at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent) for use in such exchange.

(b) Each holder of shares of Caremark Stock shall be entitled to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the aggregate Merger Consideration that such holder has a right to receive pursuant to Section 2.04. The shares of CVS Stock constituting part of such Merger Consideration, at CVS’s option, shall be in uncertificated book-entry form, unless a physical certificate is requested by a holder of shares of Caremark Stock or is otherwise required under Applicable Law. As a result of the Merger, at the Effective Time, all shares of Caremark Stock shall cease to be outstanding and each holder thereof shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable in respect thereof and any dividends or other distributions payable in respect thereof in accordance with Section 2.05(f).

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(d) At the Effective Time, there shall be no further registration of transfers of shares of Caremark Stock that were outstanding prior to the Merger.

If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration payable in respect thereof provided for, and in accordance with the procedures set forth, in this Article 2.

(e) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.05(a) that remains unclaimed by the holders of shares of Caremark Stock six months after the Effective Time shall be returned to CVS, upon demand, and any such holder who has not exchanged shares of Caremark Stock for the Merger Consideration in accordance with this Section 2.05 prior to that time shall thereafter look only to CVS for payment of the Merger Consideration, and any dividends and distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, CVS shall not be liable to any holder of shares of Caremark Stock for any amounts properly paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Caremark Stock six years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of CVS, free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends or other distributions with respect to securities of CVS constituting part of the Merger Consideration, and no cash payment in lieu of fractional shares as provided in Section 2.07, shall be paid to the holder of any Certificates not surrendered or of any Uncertificated Shares not transferred until such Certificates or Uncertificated Shares are surrendered or transferred, as the case may be, as provided in this Section. Following such surrender or transfer, there shall be paid, without interest, to the Person in whose name the securities of CVS have been registered, (i) at the time of such surrender or transfer, the amount of any cash payable in lieu of fractional shares to which such Person is entitled pursuant to Section 2.07 and the amount of all dividends or other distributions with a record date after the Effective Time previously paid or payable on the date of such surrender with respect to such securities, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and prior to surrender or transfer and with a payment date subsequent to surrender or transfer payable with respect to such securities.

Section 2.06. Stock Options. (a) The terms of each outstanding option to purchase shares of Caremark Stock under any employee stock option or compensation plan or arrangement of Caremark (a “Caremark Stock Option”), whether or not exercisable or vested, shall be adjusted as necessary to provide that, at the Effective Time, each Caremark Stock Option outstanding immediately prior to the Effective Time shall be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such Caremark Stock Option, the same number of whole shares of CVS Stock as the holder of such Caremark Stock Option would have been entitled to receive pursuant to the

Merger had such holder exercised such Caremark Stock Option in full immediately prior to the Effective Time, at a price per share of CVS Stock equal to (i) the aggregate exercise price for the shares of Caremark Stock otherwise purchasable pursuant to such Caremark Stock Option divided by (ii) the aggregate number of whole shares of CVS Stock deemed purchasable pursuant to such so adjusted Caremark Stock Option rounded up to the nearest whole cent; provided that the option price, the number of shares purchasable pursuant to each such so adjusted option and the terms and conditions of exercise of each such so adjusted option shall be determined in order to comply with Section 409A of the Code and for any Caremark Stock Option to which Section 421 of the Code applies by reason of its qualification under any of Sections 422 through 424 of the Code, the option price, the number of shares purchasable pursuant to each such so adjusted option and the terms and conditions of exercise of each such so adjusted option shall be determined in order to comply with Section 424 of the Code.

(b) Prior to the Effective Time, Caremark shall (i) use all commercially reasonable efforts to obtain any consents from holders of options to purchase shares of Caremark Stock granted under Caremark’s stock option or compensation plans or arrangements and (ii) make any amendments to the terms of such stock option or compensation plans or arrangements that are necessary to give effect to the adjustments contemplated by this Section 2.06.

(c) CVS shall take such actions as are necessary for the assumption of Caremark Stock Options pursuant to this Section 2.06, including the reservation, issuance and listing of CVS Stock as is necessary to effectuate the transactions contemplated by this Section 2.06. CVS shall prepare and file with the SEC a registration statement on an appropriate form, or a post-effective amendment to a registration statement previously filed under the 1933 Act, with respect to the shares of CVS Stock subject to Caremark Stock Options and shares issuable to directors of Caremark under the Caremark Non- Employee Director Deferred Compensation Plan and shares held in the trusts set forth in clauses (a)(3)-(5) of Section 4.05 of the Caremark Disclosure Schedule and, where applicable, shall use all commercially reasonable efforts to have such registration statement declared effective as soon as practicable following the Effective Time and to maintain the effectiveness of such registration statement covering such Caremark Stock Options and shares issuable to directors of Caremark under the Caremark Non-Employee Director Deferred Compensation Plan (and to maintain the current status of the prospectus contained therein) for so long as such Caremark Stock Options remain outstanding. With respect to those individuals, if any, who, subsequent to the Effective Time, will be subject to the reporting requirements under Section 16(a) of the 1934 Act, where applicable, CVS shall use all commercially reasonable efforts to administer Caremark Stock Options assumed pursuant to this Section 2.06 in a manner that complies with Rule 16b-3 promulgated under the 1934 Act to the extent such Caremark Stock Options complied with such rule prior to the Merger.

Section 2.07. Fractional Shares. No certificates, scrip or shares of CVS Stock representing fractional shares of CVS Common Stock or book-entry credit of the same shall be issued upon the surrender for exchange of Certificates or Uncertificated Shares, and such fractional share interests shall not entitle the owner thereof to vote or to have any rights as a stockholder of CVS by virtue of such fractional share interests. All fractional shares of CVS Stock that a holder of shares of Caremark Stock would otherwise be entitled to receive as a result of the Merger shall be aggregated and if a fractional share results from such aggregation, such holder shall be entitled to receive, in lieu thereof, an amount in cash without interest determined by multiplying the closing sale price of a share of CVS Stock on the New York Stock Exchange (the “NYSE”) on the first trading day immediately following the Effective Time by the fraction of a share of CVS Stock to which such holder would otherwise have been entitled. CVS shall deposit with the Exchange Agent the funds required to make the cash payments required by this Section 2.07 when and as needed.

Section 2.08. Withholding Rights. CVS and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 2 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If CVS or the Surviving Corporation so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which CVS or the Surviving Corporation made such deduction and withholding.

Section 2.09. Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, delivery by such Person of an agreement in form reasonably satisfactory to the Surviving Corporation or, as the Surviving Corporation may reasonably deem necessary, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Caremark Stock represented by such Certificate, as contemplated by this Article 2.

Section 2.10. Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of CVS or Caremark shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, the Exchange Ratio and any amounts payable pursuant to Section 2.05(f) or Section 2.07 of this Agreement shall be appropriately adjusted.

Section 4.02. Corporate Authorization.

Each such Caremark Subsidiary is duly qualified to do business as a foreign entity and is in good standing in each jurisdiction where such qualification is necessary, except for those jurisdictions where failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Caremark. All Significant Subsidiaries (as defined in Regulation S-X of the Exchange Act) of Caremark and their respective jurisdictions of incorporation are identified in Caremark 10-K.

(b) All of the outstanding capital stock of, or other voting securities or ownership interests in, each Caremark Subsidiary is owned by Caremark, directly or indirectly, free and clear of any Lien (other than statutory Liens for Taxes not yet payable) and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other voting securities or ownership interests). There are no outstanding (i) securities of Caremark or any of the Caremark Subsidiaries convertible into or exchangeable for shares of capital stock or other voting securities or ownership interests in any Caremark Subsidiary or (ii) options or other rights to acquire from Caremark or any of the Caremark Subsidiaries, or other obligations of Caremark or any of the Caremark Subsidiaries to issue, any capital stock or other voting securities or ownership interests in, or any securities convertible into or exchangeable for any capital stock or other voting securities or ownership interests in, any Subsidiary of Caremark (the items in clauses (i) and (ii) being referred to collectively as the “Caremark Subsidiary Securities”).

(e) Caremark has established and maintains disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act).

(f) Since January 1, 2005, Caremark and its Subsidiaries have established and maintained a system of internal control over financial reporting (as defined in Rule 13a-15 and Rule 15(d)-15(f) under the 1934 Act) (“internal controls”) sufficient to provide reasonable assurance regarding the reliability of Caremark’s financial reporting and the preparation of Caremark financial statements for external purposes in accordance with GAAP. Caremark has disclosed, based on its most recent evaluation of internal controls prior to the date

hereof, to Caremark’s auditors and audit committee (x) any significant deficiencies and material weaknesses in the design or operation of internal controls which would reasonably be expected to adversely affect Caremark’s ability to record, process, summarize and report financial information and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in internal controls.

(g) There are no outstanding loans or other extensions of credit made by Caremark or any of the Caremark Subsidiaries to any executive officer (as defined in Rule 3b-7 under the ▇▇▇▇ ▇▇▇) or director of Caremark.

The information supplied by Caremark for inclusion in the joint proxy statement/prospectus, or any amendment or supplement thereto, to be sent to the Caremark stockholders and CVS stockholders in connection with the Merger and the other transactions contemplated by this Agreement (the “Joint Proxy Statement”) shall not, on the date the Joint Proxy Statement is first mailed to the stockholders of each of Caremark and CVS, at the time of the Caremark Stockholder Approval or at the time of the CVS Stockholder Approval, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(a) Each Tax Return required by Applicable Law to be filed with any Taxing Authority by, or on behalf of, Caremark or any of its Subsidiaries has been filed when due in accordance with all Applicable Laws, and each such Tax Return is, or shall be at the time of filing, true and complete in all respects, excluding in each case any items or matters that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Caremark.

(d) There is no claim, audit or suit now pending or, to Caremark’s knowledge, threatened against or with respect to Caremark or its Subsidiaries in respect of any federal or state income Tax; additionally, no claim or suit regarding an amount of Tax is now pending in connection with (i) any other Tax Return or (ii) circumstances where no Tax Return has been filed, excluding in each case any items or matters that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Caremark.

(f) Neither Caremark nor any of its Subsidiaries has participated in a “reportable transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(1).

(g) “Tax” means (a) any tax, governmental fee or other like assessment or charge of any kind whatsoever (including withholding on amounts paid to or by any Person), together with any interest, penalty, addition to tax or additional amount imposed by any Governmental Authority (a “Taxing Authority”) responsible for the imposition of any such tax (domestic or foreign), and any liability for any of the foregoing as transferee, (b) liability for the payment of any amount of the type described in clause (a) as a result of being or having been before the Effective Time a member of an affiliated, consolidated, combined or unitary group, or a party to any agreement or arrangement, as a result of which liability to a Taxing Authority is determined or taken into account with reference to the activities of any other Person, and (c) liability for the payment of any amount as a result of being party to any Tax Sharing Agreement or with respect to the payment of any amount imposed on any Person of the type described in (a) or (b) as a result of any existing express or implied agreement or arrangement

(including an indemnification agreement or arrangement). “Tax Return” means any report, return, document, declaration or other information or filing required to be supplied to any Taxing Authority with respect to Taxes, including information returns, any documents with respect to or accompanying payments of estimated Taxes, or with respect to or accompanying requests for the extension of time in which to file any such report, return, document, declaration or other information. “Tax Sharing Agreements” means all existing agreements or arrangements (whether or not written) binding a party or any of its Subsidiaries that provide for the allocation, apportionment, sharing or assignment of any Tax liability or benefit, or the transfer or assignment of income, revenues, receipts, or gains for the purpose of determining any Person’s Tax liability (excluding any indemnification agreement or arrangement pertaining to the sale or lease of assets or subsidiaries).

Section 4.18. Employee Benefit Plans and Labor Matters. (a) Section 4.18(a) of the Caremark Disclosure Schedule contains a correct and complete list identifying each “employee benefit plan,” as defined in Section 3(3) of ERISA, each employment, severance or similar contract, plan, arrangement or policy and each other plan or arrangement (written or oral) providing for compensation, bonuses, profit-sharing, stock option or other stock-related rights or other forms of incentive or deferred compensation, vacation benefits, insurance (including any self-insured arrangements), health or medical benefits, employee assistance program, disability or sick leave benefits, workers’ compensation, supplemental unemployment benefits, severance benefits and post-employment or retirement benefits (including compensation, pension, health, medical or life insurance benefits) which covers any employee or former employee of Caremark or its Subsidiaries or its ERISA Affiliates or any of their dependents, with respect to which Caremark or any of its ERISA Affiliates has any material liability, whether current or contingent (individually, a “Caremark Employee Plan” and collectively, the “Caremark Employee Plans”). Copies of such plans (and, if applicable, related trust or funding agreements or insurance policies) and all amendments thereto and written interpretations thereof have been made available to CVS together with the most recent annual report (Form 5500 including, where applicable, all schedules) and tax return (Form 990) prepared in connection with any such plan or trust.

(b) No Caremark Employee Plan is subject to Title IV of ERISA.

(c) No Caremark Employee Plan is a multiemployer plan, as defined in Section 3(37) of ERISA (a “Multiemployer Plan”) or a multiple employer welfare arrangement as defined in Section 3(40) or ERISA (a “MEWA”).

(d) Except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Caremark, each Caremark Employee Plan that is intended to be qualified under Section 401(a) of the Code is so qualified and the plan as currently in effect has received a favorable determination letter to that effect from the Internal Revenue Service and

Caremark is not aware of any reason why any such determination letter should be revoked or not be reissued. Caremark has made available to CVS copies of the most recent Internal Revenue Service determination letters with respect to each such Caremark Employee Plan. Each Caremark Employee Plan has been maintained in compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations, including ERISA and the Code, which are applicable to such Caremark Employee Plan with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on Caremark. No events have occurred with respect to any Caremark Employee Plan that could result in payment or assessment by or against Caremark or any of its ERISA Affiliates of any excise taxes under Sections 4972, 4975, 4976, 4977, 4979, 4980B, 4980D, 4980E or 5000 of the Code with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on Caremark.

(e) There is no current or projected liability in respect of post-employment or post-retirement health or medical or life insurance benefits for retired, former or current employees of Caremark or its Subsidiaries, except as required to avoid excise tax under Section 4980B of the Code. No condition exists that would prevent Caremark or any of its ERISA Affiliates from amending or terminating any Caremark Employee Plan providing health or medical benefits in respect of any current or former employees of Caremark or its Subsidiaries other than limitations imposed under the terms of a collective bargaining agreement.

(f) All contributions and payments due under each Caremark Employee Plan, determined in accordance with prior funding and accrual practices, as adjusted to include proportional accruals for the period ending on the Effective Time, will be discharged and paid on or prior to the Effective Time except to the extent accrued as a liability in accordance with ordinary Caremark practice. There has been no amendment to, written interpretation of or announcement (whether or not written) by Caremark or any of its ERISA Affiliates relating to, or change in employee participation or coverage under, any Caremark Employee Plan which would increase materially the expense of maintaining such Caremark Employee Plan above the level of the expense incurred in respect thereof for the most recent fiscal year ended prior to the date hereof.

(g) No employee or former employee of Caremark or any of its Subsidiaries will become entitled to any bonus, retirement, severance, job security or similar benefit, or the enhancement of any such benefit, as a result of the transactions contemplated hereby alone or together with any other event. There is no contract, plan or arrangement (written or otherwise) covering any employee or former employee of Caremark or any of its Subsidiaries that, individually or collectively, could give rise to the payment of any amount that would not be deductible pursuant to the terms of Sections 280G or 162(m) of the Code, as a result of the transactions contemplated hereby alone or together with any other event.

(h) There is no material action, suit, investigation, audit or proceeding (i) pending against or involving or, to the knowledge of Caremark, threatened against any Caremark Employee Plan or (ii) involving Caremark’s classification of individuals as either employees or independent contractors, in each case, before any arbitrator or any Governmental Authority.

(i) Neither Caremark nor any of its Subsidiaries is a party to or subject to, or is currently negotiating in connection with entering into, any collective bargaining agreement or other contract or understanding with a labor union or organization. Neither Caremark nor any of its Subsidiaries is the subject of any material proceeding asserting that Caremark or any of its Subsidiaries has violated any wage-hour Law or employment discrimination Law or committed an unfair labor practice or seeking to compel it to bargain with any labor union or labor organization nor is there pending or, to the knowledge of Caremark, threatened, nor has there been for the past five years, any labor strike, material dispute, walk-out, work stoppage, slow-down or lockout involving Caremark or any of its Subsidiaries with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on Caremark or its Subsidiaries. To the knowledge of Caremark, as of the date hereof, there are no campaigns being conducted to solicit cards from Caremark employees to authorize (or to express an interest in authorizing) representation by a labor organization or other proposed bargaining unit representative.

Section 4.19. Environmental Matters. (a) Except as to matters that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Caremark:

(i) no written notice, notification, demand, request for information, citation, summons or order has been received by Caremark or any of its Subsidiaries relating to or arising out of any Environmental Law;

(ii) there are no judicial, administrative or other actions, suits or proceedings pending or, to the knowledge of Caremark, threatened against Caremark or any of its Subsidiaries which allege a violation of, or liability under, any Environmental Law;

(iii) Caremark and its Subsidiaries are in compliance with all Environmental Laws; and

(iv) Caremark and its Subsidiaries have obtained and are in compliance with all Environmental Permits and such Environmental Permits are valid and in full force and effect.

(b) Except as set forth in this Section 4.19 and in Section 4.03, no representations or warranties are being made with respect to environmental matters relating to Caremark or any of its Subsidiaries.

Section 4.20. Tax Treatment. Neither Caremark nor any of its Affiliates has taken or agreed to take any action, or is aware of any fact or circumstance, that would prevent the Merger from qualifying as a reorganization within the meaning of Section 368 of the Code (a “368 Reorganization”).

Section 4.21. Antitakeover Statutes. (a) Caremark has taken all action necessary to exempt the Merger, this Agreement and the transactions contemplated hereby from the restrictions on business combinations set forth in Section 203 of Delaware Law, and, accordingly, neither the restrictions on business combinations set forth in such Section nor in any other antitakeover or similar statute or regulation applies or purports to apply to the Merger or any other transactions contemplated by this Agreement. No other “control share acquisition,” “fair price,” “moratorium” or other antitakeover laws enacted under U.S. state or federal laws apply to this Agreement or any of the transactions contemplated hereby.

(f) Neither CVS nor any of its Subsidiaries has participated in a “reportable transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(1).

Section 5.18. Employee Benefit Plans and Labor Matters. (a) Section 5.18(a) of the CVS Disclosure Schedule contains a correct and complete list identifying each “employee benefit plan,” as defined in Section 3(3) of ERISA, each employment, severance or similar contract, plan, arrangement or policy and each other plan or arrangement (written or oral) providing for compensation, bonuses, profit-sharing, stock option or other stock-related rights or other forms of incentive or deferred compensation, vacation benefits, insurance (including any self-insured arrangements), health or medical benefits, employee assistance program, disability or sick leave benefits, workers’ compensation, supplemental unemployment benefits, severance benefits and post-employment or retirement benefits (including compensation, pension, health, medical or life insurance benefits) which covers any employee or former employee of CVS or its Subsidiaries or its ERISA Affiliates or any of their dependents, or with respect to which CVS or any of its ERISA Affiliates has any material liability, whether current or contingent (individually, a “CVS Employee Plan” and collectively, the “CVS Employee Plans”). Copies of such plans (and, if applicable, related trust or funding agreements or insurance policies) and all amendments thereto and written interpretations thereof have been made available to Caremark together with the most recent annual report (Form 5500 including, where applicable, all schedules) and tax return (Form 990) prepared in connection with any such plan or trust.

(b) No CVS Employee Plan is subject to Title IV of ERISA.

(d) Except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on CVS, each CVS Employee Plan that is intended to be qualified under Section 401(a) of the Code is so qualified and the plan as currently in effect has received a favorable determination letter to that effect from the Internal Revenue Service and CVS is not aware of any reason why any such determination letter should be revoked or not be reissued. CVS has made available to Caremark copies of the most recent Internal Revenue Service determination letters with respect to each such CVS Employee Plan. Each CVS Employee Plan has been maintained in compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations, including ERISA and the Code, which are applicable to such CVS Employee Plan with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on CVS. No events have occurred with respect to any CVS Employee Plan that could result in payment or assessment by or against CVS or any of its ERISA Affiliates of any excise taxes under Sections 4972, 4975, 4976, 4977, 4979, 4980B, 4980D, 4980E or 5000 of the Code with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on CVS.

(e) There is no current or projected liability in respect of post-employment or post-retirement health or medical or life insurance benefits for retired, former or current employees of CVS or its Subsidiaries, except as required to avoid excise tax under Section 4980B of the Code. No condition exists that would prevent CVS or any of its ERISA Affiliates from amending or terminating any CVS Employee Plan providing health or medical benefits in respect of any current or former employees of CVS or its Subsidiaries other than limitations imposed under the terms of a collective bargaining agreement.

(f) All contributions and payments due under each CVS Employee Plan, determined in accordance with prior funding and accrual practices, as adjusted to include proportional accruals for the period ending on the Effective Time, will be discharged and paid on or prior to the Effective Time except to the extent accrued as a liability in accordance with ordinary CVS practice. There has been no amendment to, written interpretation of or announcement (whether or not written) by CVS or any of its ERISA Affiliates relating to, or change in employee participation or coverage under, any CVS Employee Plan which would increase materially the expense of maintaining such CVS Employee Plan above the level of the expense incurred in respect thereof for the most recent fiscal year ended prior to the date hereof.

(g) No employee or former employee of CVS or any of its Subsidiaries will become entitled to any bonus, retirement, severance, job security or similar benefit, or the enhancement of any such benefit, as a result of the transactions contemplated hereby alone or together with any other event. There is no contract, plan or arrangement (written or otherwise) covering any employee or former employee of CVS or any of its Subsidiaries that, individually or collectively, could give rise to the payment of any amount that would not be deductible pursuant to the terms of Sections 280G or 162(m) of the Code, as a result of the transactions contemplated hereby alone or together with any other event.

(h) There is no material action, suit, investigation, audit or proceeding (i) pending against or involving or, to the knowledge of CVS, threatened against, any CVS Employee Plan or (ii) involving CVS’s classification of individuals as either employees or independent contractors, in each case, before any arbitrator or any Governmental Authority.

(i) Neither CVS nor any of its Subsidiaries is a party to or subject to, or is currently negotiating in connection with entering into, any collective bargaining agreement or other contract or understanding with a labor union or organization. Neither CVS nor any of its Subsidiaries is the subject of any material proceeding asserting that CVS or any of its Subsidiaries has violated any wage-hour Law or employment or discrimination Law or committed an unfair labor practice or seeking to compel it to bargain with any labor union or labor organization nor is

there pending or, to the knowledge of CVS, threatened, nor has there been for the past five years, any labor strike, material dispute, walk-out, work stoppage, slow-down or lockout involving CVS or any of its Subsidiaries with such exceptions as would not be reasonably expected, individually or in the aggregate, to have a Material Adverse Effect on CVS or its Subsidiaries. To the knowledge of CVS, as of the date hereof, there are no campaigns being conducted to solicit cards from CVS employees to authorize (or to express an interest in authorizing) representation by a labor organization or other proposed bargaining unit representative.

Section 5.19. Environmental Matters. (a) Except as to matters that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on CVS:

(i) no written notice, notification, demand, request for information, citation, summons or order has been received by CVS or any of its Subsidiaries relating to or arising out of any Environmental Law;

(ii) there are no judicial, administrative or other actions, suits or proceedings pending or, to the knowledge of CVS, threatened against CVS or any of its Subsidiaries which allege a violation of, or liability under, any Environmental Law;

(iii) CVS and its Subsidiaries are in compliance with all Environmental Laws; and

(iv) CVS and its Subsidiaries have obtained and are in compliance with all Environmental Permits and such Environmental Permits are valid and in full force and effect.

(b) Except as set forth in this Section 5.19 and Section 5.03, no representations or warranties are being made with respect to environmental matters relating to CVS or any of its Subsidiaries.

Section 5.20. Tax Treatment. Neither CVS nor any of its Affiliates has taken or agreed to take any action, or is aware of any fact or circumstance, that would prevent the Merger from qualifying as a 368 Reorganization.

Section 5.21. Antitakeover Statutes. (a) CVS has taken all action necessary to exempt the Merger, this Agreement and the transactions contemplated hereby from the restrictions on business combinations set forth in Section 203 of Delaware Law, and, accordingly, neither the restrictions on business combinations set forth in such Section nor in any other antitakeover or similar statute or regulation applies or purports to apply to the Merger or any other transaction contemplated by this Agreement. No other “control share acquisition,” “fair price,” “moratorium” or other antitakeover laws enacted under U.S. state or federal laws apply to this Agreement or any of the transactions contemplated hereby.

(b) CVS has taken all action necessary to render Article Fifth of CVS’s amended restated certificate of incorporation as inapplicable to the Merger, this Agreement and the other transactions contemplated hereby.

ARTICLE 8

COVENANTS OF CVS AND CAREMARK

The parties hereto agree that:

Section 8.01. Reasonable Best Efforts. (a) Subject to the terms and conditions of this Agreement, each of Caremark and CVS shall 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 this Agreement, including (i) 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 (ii) 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 this Agreement; provided that the parties hereto understand and agree that in no event shall any party be required by this Section 8.01 or any other provision of this Agreement (i) to enter into any settlement, undertaking, consent decree, stipulation or agreement with any Governmental Authority in connection with the transactions contemplated hereby or (ii) 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 in any such case in (i) or (ii) that would reasonably be expected to (x) materially and adversely diminish the benefits expected to be derived by the parties on the date of this 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 such party would not have entered into this Agreement in the face of such materially and adversely diminished benefits or (y) otherwise have a Material Adverse Effect after the Effective Time on CVS and its Subsidiaries (including the Surviving Corporation), taken as a whole, ignoring for this purpose only clause (vi) of the definition of Material Adverse Effect insofar as it relates to the matters under consideration with respect to the applicable provision of this Agreement (as described in this clause (y), a “Regulatory Material Adverse Effect”).

(b) In furtherance and not in limitation of the foregoing, each of CVS and Caremark shall make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable and in any event within thirty (30) Business Days of the date hereof and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and to take all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable.

Section 8.02. Certain Filings. (a) As soon as practicable (but in no event later than 45 days after the date of this Agreement) following the date of this Agreement, CVS and Caremark shall jointly prepare and file with the SEC the Joint Proxy Statement, and CVS and Caremark jointly shall prepare and file with the SEC the Registration Statement (in which the Joint Proxy Statement will be included). Each of CVS and Caremark shall use all commercially reasonable efforts to have the Joint Proxy Statement cleared by the SEC and the Registration Statement declared effective under the 1933 Act as promptly as practicable after the filing thereof and to keep the Registration Statement effective as long as is necessary to consummate the Merger.

(b) Each of Caremark and CVS shall provide the other parties and their respective counsel with (i) any comments or other communications, whether written or oral, that such party or its counsel may receive from time to time from the SEC or its staff with respect to the Joint Proxy Statement or the Registration Statement, as applicable, promptly after receipt of those comments or other communications and (ii) a reasonable opportunity to participate in the response to those comments.

(c) No amendment or supplement to the Joint Proxy Statement or the Registration Statement will be made by CVS or Caremark without the approval of the other parties hereto, which approval shall not be unreasonably withheld or delayed. Each party will advise the other parties, promptly after it receives notice thereof, of the time when the Registration Statement has become effective or any

supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of CVS Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Joint Proxy Statement or the Registration Statement. If, at any time prior to the Effective Time, CVS or Caremark discovers any information relating to any party, or any of their respective Affiliates, officers or directors, that should be set forth in an amendment or supplement to the Joint Proxy Statement or the Registration Statement, so that none of those documents would include any misstatement of a material fact or omit to state any material fact necessary to make the statements in any such document, in light of the circumstances under which they were made, not misleading, the party that discovers that information shall promptly notify the other party and an appropriate amendment or supplement describing that information shall be promptly filed with the SEC and, to the extent required by law or regulation, disseminated to the stockholders of CVS and Caremark.

(d) CVS and Caremark shall cooperate with one another in (i) determining whether any action by or in respect of, or filing with, any Governmental Authority is required, or any actions, consents, approvals or waivers are required to be obtained from any Governmental Authority, in connection with the consummation of the transactions contemplated by this Agreement, (ii) seeking any of those actions, consents, approvals or waivers or making any of those filings, furnishing information required in connection therewith and seeking promptly to obtain any of those actions, consents, approvals or waivers and (iii) setting a mutually acceptable date for CVS Stockholder Meeting and Caremark Stockholder Meeting, so as to enable them to occur, to the extent practicable, on the same date. Each party shall permit the other party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, any Governmental Authority and to the extent permitted by the applicable Governmental Authority, give the other party the opportunity to attend and participate in those meetings and conferences, in each case in connection with the transactions contemplated by this Agreement.

Section 8.03. Public Announcements. (a) Caremark and CVS shall consult with each other before issuing any press release, making any other public statement or scheduling any press conference or conference call with investors or analysts with respect to this Agreement or the transactions contemplated by this Agreement and, except as may be required by applicable law, order of a court of competent jurisdiction or any listing agreement with or rule of any regulatory body, national securities exchange or association, shall not issue any such press release, make any such other public statement or schedule any such press conference or conference call before that consultation. The initial press release of the parties shall be a joint press release of CVS and Caremark in the form that is mutually agreed.

(b) Before any Merger Communication of Caremark, CVS or any of their respective “participants” (as defined in Rule 165 of the Securities Act or Item 4 of Schedule 14A of the Exchange Act) is (i) disseminated to any investor, analyst, member of the media, employee, client, customer or other third-party or otherwise made accessible on the website of Caremark, CVS or any such participant, as applicable (whether in written, video or oral form via webcast, hyperlink or otherwise), or (ii) utilized by any executive officer, key employee or advisor of Caremark, CVS or any such participant, as applicable, as a script in discussions or meetings with any such third parties, Caremark or CVS, as the case may be, shall (or shall cause any such participant to) cooperate in good faith with respect to any such Merger Communication for purposes of, among other things, determining whether that communication (x) is required to be filed under Rules 165 and 425 of the Exchange Act or (y) constitutes “soliciting material” that is required to be filed by Rule 14a-6(b) or Rule 14a-12(b) of the Exchange Act, as applicable. Caremark, MergerSub or CVS, as applicable, shall (or shall cause any such participant to) give reasonable and good faith consideration to any comments made by the other such party or parties and their counsel on any such Merger Communication. For purposes of the foregoing, the term “Merger Communication” shall mean, with respect to any Person, any document or other written communication prepared by or on behalf of that Person, or any document or other material or information posted or made accessible on the website of that Person (whether in written, video or oral form via webcast, hyperlink or otherwise), that is related to any of the transactions contemplated by this Agreement and, if reviewed by a relevant stockholder, could reasonably be deemed to constitute either (x) an offer to sell such stock or a solicitation of an offer to buy CVS Stock or (y) a “solicitation” of “proxies” (in each case, as defined in Rule 14a-1 of the Exchange Act) in favor of the Merger.

Section 8.04. Stockholder Meetings. (a) Caremark shall use all commercially reasonable efforts in accordance with and subject to Delaware Law, its certificate of incorporation and bylaws and the rules of the NYSE to cause a meeting of its stockholders (the “Caremark Stockholder Meeting”) to be duly called and held as soon as reasonably practicable for the purpose of voting on the approval and adoption of this Agreement and the Merger. Subject to Section 8.07, the Joint Proxy Statement shall contain the recommendation of the Board of Directors of Caremark that Caremark’s stockholders approve and adopt this Agreement and the Merger (the “Caremark Recommendation”). In connection with the Caremark Stockholder Meeting, Caremark shall (i) mail the Joint Proxy Statement and all other proxy materials for such meeting to its stockholders as promptly as practicable after the Registration Statement is declared effective under the 1933 Act, (ii) use all commercially reasonable efforts to obtain Caremark Stockholder Approval and (iii) otherwise comply with all legal requirements applicable to such meeting. Without limiting the generality of the foregoing, this Agreement and the Merger shall be submitted to Caremark’s stockholders at the Caremark Stockholder Meeting whether or not (x) Caremark’s Board of Directors shall have effected an Adverse Recommendation Change or (y) any Acquisition Proposal shall have been publicly proposed or announced or otherwise submitted to Caremark or any of its advisors.

(b) CVS shall use all commercially reasonable efforts in accordance with and subject to Delaware Law, its certificate of incorporation and bylaws and the rules of the NYSE to cause a meeting of its stockholders (the “CVS Stockholder Meeting”) to be duly called and held as soon as reasonably practicable for the purpose of securing the CVS Stockholder Approval. Subject to Section 8.07, the Joint Proxy Statement shall contain the recommendation of the Board of Directors of CVS that CVS’s stockholders approve the CVS Share Issuance and the CVS Charter Amendment (the “CVS Recommendation”). In connection with the CVS Stockholder Meeting, CVS shall (i) mail the Joint Proxy Statement and all other proxy materials for such meeting to its stockholders as promptly as practicable after the Registration Statement is declared effective under the 1933 Act, (ii) use all commercially reasonable efforts to obtain CVS Stockholder Approval and (iii) otherwise comply with all legal requirements applicable to such meeting. Without limiting the generality of the foregoing, the CVS Share Issuance and the CVS Charter Amendment shall be submitted to CVS’s stockholders at the CVS Stockholder Meeting whether or not (x) CVS’s Board of Directors shall have effected an Adverse Recommendation Change or (y) any Acquisition Proposal shall have been publicly proposed or announced or otherwise submitted to CVS or any of its advisors.

Section 8.05. Director and Officer Liability. CVS shall cause the Surviving Corporation, and the Surviving Corporation hereby agrees, to do the following:

(a) CVS shall, and shall cause the Surviving Corporation to, indemnify and hold harmless the present and former officers and directors of Caremark (or its Subsidiaries) (each an “Indemnified Person”) in respect of acts or omissions occurring at or prior to the Effective Time to the fullest extent permitted by Delaware Law or any other Applicable Law or provided under Caremark’s certificate of incorporation and bylaws in effect on the date hereof; provided that such indemnification shall be subject to any limitation imposed from time to time under Applicable Law.

(b) For six years after the Effective Time, CVS shall provide officers’ and directors’ liability insurance in respect of acts or omissions occurring prior to the Effective Time covering each such Indemnified Person currently covered by Caremark’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect on the date hereof; provided that, in satisfying its obligation under this Section 8.05(b), CVS shall not be obligated to pay an aggregate annual premium in excess of the amounts described on Section 7.04(b) of the CVS Disclosure Schedule. In the event that, but for the proviso to the immediately preceding sentence, the Surviving Corporation would be required to expend more than the amount set forth on that Section of the CVS Disclosure Schedule, the Surviving

Corporation shall obtain the maximum amount of insurance obtainable having the terms and scope of coverage of the relevant existing Caremark policy and covering facts, events, acts and omissions occurring prior to the Effective Time by payment of annual premiums equal to such amount.

(c) If CVS, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of CVS or such Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 8.05.

(d) The rights of each Indemnified Person under this Section 8.05 shall be in addition to any rights such Person may have under the certificate of incorporation or bylaws of Caremark or any of their respective Subsidiaries, or under Delaware Law or any other Applicable Law or under any agreement of any Indemnified Person with Caremark or any of its Subsidiaries. These rights shall survive consummation of the applicable Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.

Section 8.06. Stock Exchange Listing. CVS shall use its all commercially reasonable efforts to cause the shares of CVS Stock to be issued in connection with the Merger to be listed on the New York Stock Exchange, subject to official notice of issuance.

Section 8.07. No Solicitation; Other Offers.

(a) General Prohibitions. Subject to the remainder of this Section 8.07, neither Caremark or CVS (either, a “No-Shop Party”) nor any of its Subsidiaries shall, nor shall a No-Shop Party or any of its Subsidiaries authorize or permit any of its or their officers, directors, employees, investment bankers, attorneys, accountants, consultants or other agents or advisors to, directly or indirectly, (i) solicit, initiate or take any action to knowingly facilitate or encourage the submission of any Acquisition Proposal, (ii) enter into or participate in any discussions or negotiations with, furnish any information relating to that No-Shop Party or any of its Subsidiaries or afford access to the business, properties, assets, books or records of that No-Shop Party or any of its Subsidiaries to, otherwise cooperate in any way with, or knowingly assist, participate in, knowingly facilitate or encourage any effort by any Third Party that is seeking to make, or has made, an Acquisition Proposal, (iii) make an Adverse Recommendation Change, (iv) grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of that No-Shop Party or any of its Subsidiaries, (v) enter into any agreement in principle, letter of intent, term sheet or other similar instrument relating to an Acquisition Proposal (other than a confidentiality agreement of the sort and in the circumstances described in Section 8.07(b)) or (vi) propose publicly or agree to do any of the foregoing related to any Acquisition Proposal.

(b) Exception to Permit Discussions and/or Due Diligence. Notwithstanding the foregoing, the Board of Directors of a No-Shop Party, directly or indirectly through advisors, agents or other intermediaries, may, prior to CVS Stockholder Approval (in the case of CVS) or Caremark Stockholder Approval (in the case of Caremark), (i) engage in negotiations or discussions with any Third Party that, subject to such No-Shop Party’s compliance with Section 8.07(a), has made an unsolicited bona fide written Acquisition Proposal that such No-Shop Party’s Board of Directors has determined in good faith (after consultation with its outside legal counsel and financial advisors) constitutes or is reasonably likely to lead to a Superior Proposal and (ii) thereafter furnish to such Third Party non-public information relating to that No-Shop Party or any of its Subsidiaries pursuant to a confidentiality agreement with terms no less favorable to that No-Shop Party than those contained in the Confidentiality Agreement dated as of October 6, 2006 between Caremark and CVS (the “Confidentiality Agreement”) (a copy of which shall be provided for informational purposes only to the other party), but in each case referred to in the foregoing clauses (i) and (ii) only if the Board of Directors of that No-Shop Party determines in good faith by a majority vote, after considering advice from outside legal counsel to that No-Shop Party, that failing to take that action would be inconsistent with its fiduciary duties under Applicable Law. Nothing contained herein shall prevent the Board of Directors of a No-Shop Party from complying with Rule 14e-2(a) under the 1934 Act with regard to an Acquisition Proposal, so long as any action taken or statement made to so comply is consistent with this Section 8.07.

(c) Required Notices. The Board of Directors of a No-Shop Party shall not take any of the actions referred to in clauses (i) and (ii) of the preceding subsection unless that No-Shop Party shall have delivered to the other Party a prior written notice advising such other party that it intends to take such action, and that No-Shop Party shall continue to advise such other Person after taking such action. In addition, a No-Shop Party shall notify the other party promptly (but in no event later than 24 hours) after receipt by that No-Shop Party, or any of its advisors) of any Acquisition Proposal, any indication that a Third Party is considering making an Acquisition Proposal or of any request for information relating to such No-Shop Party or any of its Subsidiaries or for access to the business, properties, assets, books or records of such No-Shop Party or any of its Subsidiaries by any Third Party that may be considering making, or has made, an Acquisition Proposal. Such No-Shop Party shall provide such notice orally and in writing and shall identify the Third Party making, and the terms and conditions of, any such Acquisition Proposal, indication or request. A No-Shop Party shall keep the other Party reasonably informed, on a current basis, of the status and details of any such Acquisition Proposal, indication or request.

(d) Ability to Change Recommendation Subject to a “Last Look”. Notwithstanding anything in this Agreement to the contrary (but subject to the

next sentence), a No-Shop Party and its Board of Directors shall be permitted to effect an Adverse Recommendation Change if (i) such No-Shop Party shall not have received the Caremark Stockholder Approval (in the case of Caremark) or the CVS Stockholder Approval (in the case of CVS), (ii) it has received an unsolicited bona fide written Acquisition Proposal from a third party, (iii) its Board of Directors has determined in good faith (after consultation with its outside legal counsel and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal and (iv) its Board of Directors, after consultation with its outside legal counsel, determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under Applicable Law. However, the Board of Directors of a No-Shop Party shall nevertheless not make such an Adverse Recommendation Change, unless, (x) such No-Shop Party promptly notifies the other party, in writing at least five Business Days before taking that action, of its intention to make an Adverse Recommendation Change and attaching the most current version of any proposed agreement or a detailed summary of all material terms of any such proposal and the identity of the offeror, and (y) the other party does not propose, within five Business Days after its receipt of that written notification, such adjustments to the terms and conditions of this Agreement as would enable the No-Shop Party’s Board of Directors to proceed with its recommendation to its stockholders without an Adverse Recommendation Change. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of re-starting the five Business Day clock described in the immediately preceding sentence.

(e) Obligation to Terminate Existing Discussions. Each No-Shop Party shall, and shall cause its Subsidiaries and the advisors, employees and other agents of such No-Shop Party to, cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party conducted prior to the date hereof with respect to any Acquisition Proposal and shall use all commercially reasonable efforts to cause any such Third Party (or its agents or advisors) in possession of confidential information about that No-Shop Party that was furnished by or on behalf of that No-Shop Party to return or destroy all such information.

(f) Definition of Superior Proposal. For purposes of this Agreement, “Superior Proposal” means any bona fide, unsolicited written Acquisition Proposal (which definition shall be read, for this purpose, without the word “inquiry” in the third line thereof) for at least a majority of the outstanding shares of Caremark Stock or CVS Stock (as the case may be) on terms that the Board of Directors of a No-Shop 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 consummation and long-term strategic considerations, are more favorable from a financial point of view to the stockholders of such No-Shop 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 No-Shop Party.

(g) Certain Clarifications. If the Board of Directors of a No-Shop Party remains committed to making an Adverse Recommendation Change in favor of a Superior Proposal at the end of the 5-Business Day period referred to in Section 8.07(d), the parties hereby agree that, subject to compliance with Section 8.07(d) and in order to enable such Board of Directors to be sufficiently comfortable that the Superior Proposal will remain available to that No-Shop Party when and if this Agreement is terminated, such No-Shop Party may enter into a binding letter agreement with the Third Party making that Superior Proposal, which letter agreement (x) may provide that such Third Party is obligated, on behalf of that No-Shop Party, to make the payment required to be made by that No-Shop Party pursuant to the relevant provisions of Section 11.04 of this Agreement on the occurrence of a Caremark Payment Event or a CVS Payment Event (as applicable) in accordance with the terms thereof and (y) may attach as an exhibit thereto a fully negotiated and executed agreement and plan of merger (a “Conditional Merger Agreement”) relating to that Superior Proposal providing that such Conditional Merger Agreement is binding on the relevant No-Shop Party and Third Party at that time, but will only become effective on and after (and in no event before) both the (i) termination of this Agreement in accordance with its terms and (ii) the payment by such Third Party of the fee required to be paid under Section 11.04 on behalf of that No-Shop Party to the other party hereto. Notwithstanding the foregoing, the parties further agree that in the circumstances described in the immediately preceding sentence, until the termination of this Agreement in accordance with its terms, (1) in no event may the No-Shop Party entering into such letter agreement and Conditional Merger Agreement make any SEC or other regulatory filings in connection with the transactions contemplated by such letter agreement and Conditional Merger Agreement until the termination of this Agreement, and (2) such No-Shop Party shall otherwise remain subject to all of its obligations under this Agreement (including Section 8.01, Section 8.04 and this Section 8.07).

Section 8.08. Further Assurances. At and after the Effective Time, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of Caremark or MergerSub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Caremark or MergerSub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets of Caremark acquired or to be acquired by such Surviving Corporation as a result of, or in connection with, the Merger.

Section 8.09. Access to Information. From the date hereof until the Effective Time and subject to Applicable Law and the Confidentiality Agreement, Caremark and CVS shall (i) give to the other party, its counsel, financial advisors,

auditors and other authorized representatives reasonable access during normal business hours to the offices, properties, books and records of such party (excluding access to perform physical examinations and to take samples of the soil, ground water, air, products or other areas as desired by such other party), (ii) furnish to the other party, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct its employees, counsel, financial advisors, auditors and other authorized representatives to cooperate with the other party in its investigation. Any investigation pursuant to this Section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other party. No information or knowledge obtained in any investigation pursuant to this Section shall affect or be deemed to modify any representation or warranty made by any party hereunder.

Section 8.10. Notices of Certain Events. Each party shall promptly notify the others of:

(a) any material notice or other material communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, which consent would be material to CVS and its Subsidiaries taken as a whole after giving effect to the Merger;

(b) any material notice or other material communication from any Governmental Authority in connection with the transactions contemplated by this Agreement;

(c) any actions, suits, claims, investigations or proceedings commenced or, to its knowledge, threatened against, relating to or involving or otherwise affecting Caremark or any of its Subsidiaries or CVS and any of its Subsidiaries, as the case may be, that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to any of such party’s representations or warranties, as the case may be, or that relate to the consummation of the transactions contemplated by this Agreement;

(d) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term hereof that would reasonably be expected to cause any condition set forth in Article 9 not to be satisfied; and

(e) any failure of that party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder that would reasonably be expected to cause any condition set forth in Article 9 not to be satisfied;

provided that the delivery of any notice pursuant to this Section 8.10 shall not limit or otherwise affect the remedies available hereunder to the party receiving that notice.

Section 8.11. Tax-free Reorganization. Prior to the Effective Time, each of CVS and Caremark shall use all commercially reasonable efforts to cause the Merger to qualify as a 368 Reorganization and shall not take any action reasonably likely to cause the Merger not to so qualify. CVS shall not take, or cause the Surviving Corporation to take, any action after the Effective Time reasonably likely to cause the Merger not to qualify as a 368 Reorganization.

Section 8.12. Affiliates.

Mr. ▇▇▇ ▇▇▇▇▇▇▇▇, current Chairman, Chief Executive Officer and President of Caremark, shall serve as Chairman of the Board of Directors of CVS at the Effective Time.

(d) Board of Directors of CVS. After the date hereof, CVS and Caremark shall determine the size of the Board of Directors of CVS (which shall be an even number) as of the Effective Time. CVS shall take all actions necessary so that at the Effective Time, (i) the total number of directors serving on the Board of Directors of CVS shall reflect the foregoing agreement (by way of the members of the Board of Directors of CVS immediately before the Effective Time electing the individuals who are to be Caremark Directors to become members of CVS’s Board of Directors at the Effective Time) and (ii) the Board of Directors shall be composed of an equal number of CVS Directors and Caremark Directors. The persons who shall serve as CVS Directors and as Caremark Directors of CVS’s Board of Directors at the Effective Time shall be selected by the Boards of Directors, prior to the Effective Time, of CVS and Caremark, respectively; provided that, for the sake of clarity, ▇▇. ▇▇▇▇▇▇ ▇. ▇▇▇▇ will be one of the CVS Directors, and Mr. ▇▇▇ ▇▇▇▇▇▇▇▇ will be one of the Caremark Directors.

Section 8.16. Dividends. After the date of this Agreement, each of CVS and Caremark shall coordinate with the other the declaration of any dividends in respect of CVS Stock and Caremark Stock with the mutual intention and goal that holders of CVS Stock and Caremark Stock shall not receive two dividends or fail to receive one dividend, for any quarter with respect to those shares, on the one hand, and the CVS Stock issuable in respect of those shares pursuant to the Merger, on the other.

Section 8.17. Control of Operations. Notwithstanding anything in this Agreement that may be deemed to the contrary, nothing in this Agreement shall,

directly or indirectly, give any party control over any other party’s operations, business or decision-making before the Effective Time, and control over all such matters shall remain in the hands of the relevant party, subject to the terms and conditions of this Agreement.

Section 8.18. Employee Matters. (a) From and after the Effective Time, the Caremark Employee Plans and the CVS Employee Plans in effect at the Effective Time will remain in effect (except as provided in Section 2.06) with respect to employees and former employees of Caremark or CVS and their Subsidiaries, as applicable, and the dependents of such employees covered by such plans at the Effective Time (the “Covered Employees”), until such time as CVS otherwise determines, subject to applicable law, the terms of such plans and this Section 8.18. Prior to the Effective Time, Caremark and CVS acting in good faith will cooperate in reviewing, evaluating and analyzing the Caremark Employee Plans and the CVS Employee Plans with a view towards developing appropriate employee benefit and compensation plans, programs and arrangements for Covered Employees after the Effective Time which, among other things, (i) will treat similarly situated Covered Employees on a substantially equivalent basis, taking into account all relevant factors, including duties, responsibilities, geographic location, tenure, and qualifications and (ii) will not discriminate between Covered Employees who at the Effective Time are covered by Caremark Employee Plans, on the one hand, and those covered by CVS Employee Plans, on the other hand, and which CVS will adopt subject to customary rights to subsequently amend or terminate such plans as CVS thereafter deems appropriate (individually a “New Benefit Plan” and collectively the “New Benefits Plans”).

(b) Each New Benefit Plan will (i) provide all of the Covered Employees eligible to participate in such plans with service credit for purposes of eligibility, participation, vesting and levels of benefits (but not for benefit accruals under any defined benefit pension plan or any retiree medical or other pos-retirement welfare plan or as would otherwise result in a duplication of benefits) for all periods of employment with Caremark or CVS or any of their respective Subsidiaries (or their predecessor entities) prior to the Effective Time, (ii) cause any pre-existing conditions or limitations, eligibility, waiting periods or required physical examinations under any New Benefit Plan which is a welfare plan to be waived with respect to the Covered Employees and their eligible dependents, to the extent waived under the corresponding plan in which the applicable Covered Employees participated immediately prior to the Effective Time and, with respect to life insurance coverage, up to the Covered Employee’s current level of insurability, and (iii) give the Covered Employees and their eligible dependents credit for the plan year in which the Effective Time (or the date of commencement of participation in such New Benefit Plan) occurs towards applicable deductibles and annual out-of-pocket limits for expenses incurred prior to the Executive Time (or the date of commencement of participation in such new Benefit Plan).

(c) At the Effective Time, CVS will assume, or cause the Surviving Corporation to assume, the employment agreements and change in control agreements referred to in Section 8.18 of the Caremark Disclosure Schedule, unless such agreements are superseded by new arrangements pursuant to an agreement executed by CVS and the relevant employee. CVS shall offer to each Designated Officer of Caremark the ability to enter into an agreement substantially in the form set forth in Section 8.18(c) of the CVS Disclosure Schedule.

(d) CVS shall amend CVS’s Employee Stock Purchase Plan so that Caremark employees shall have the right to make purchases under this plan effective as soon as possible, but in no event later than the first purchase period after the Effective Time.

(e) From and after the Effective Time, 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 the Caremark Employee Plans or CVS Employee Plans, as applicable, to the extent accrued and vested as of the Effective Time.

(f) (i) Nothing in this Section 8.18 shall be treated as an amendment of any Caremark Employee Plan or any CVS Employee Plan (or an undertaking to amend any such plan), (ii) nothing in this Section 8.18 will prohibit CVS from amending, modifying or terminating any Caremark Employee Plan or CVS Employee Plan pursuant to, and in accordance with, the terms thereof, and (iii) nothing in this Section 8.18 shall confer any rights or benefits on any person other than Caremark and CVS.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 11.04. Expenses. (a) Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense. Notwithstanding the foregoing, CVS and Caremark each shall pay 50% of (i) any fees and expenses, other than attorneys’ and accounting fees and expenses, incurred in respect of the printing, filing and mailing of the Joint Proxy Statement and (ii) 50% of any and all filing fees due in connection with the filings required by or under the HSR Act.

(c) If a CVS Payment Event (as hereinafter defined) occurs, CVS shall pay Caremark (by wire transfer of immediately available funds), within two (2) Business Days following such Payment Event, a fee of $675,000,000.00. “CVS

Payment Event” means the termination of this Agreement pursuant to (x) Section 10.01(d)(i) or (y) Section 10.01(b)(i) or Section 10.01(b)(iii)(A) but (in the case of this clause (y)) only if (A) prior to the CVS Stockholder Meeting an Acquisition Proposal shall have been made to CVS or shall have been made directly to the stockholders of CVS generally or shall have otherwise become publicly known or any Person shall have publicly announced an intention (whether or not conditional and whether or not withdrawn) to make an Acquisition Proposal and (B) within 12 months following the date of such termination: (1) CVS merges with or into, or is acquired, directly or indirectly, by merger or otherwise by, a Third Party; (2) a Third Party, directly or indirectly, acquires more than 50% of the total assets of CVS and its Subsidiaries, taken as a whole; (3) a Third Party, directly or indirectly, acquires more than 50% of the outstanding shares of CVS Stock or (4) CVS or any CVS Subsidiary(ies) shall have entered into any contract or agreement providing for any of the actions described in any of the immediately preceding clauses (1) through (3).

(d) Each of CVS and Caremark acknowledges that the agreements contained in this Section 11.04 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, neither party would enter into this Agreement. Accordingly, if CVS or Caremark fails promptly to pay any amount due to the other party pursuant to this Section 11.04, the non-paying party shall also pay any costs and expenses incurred by such other party in connection with a legal action to enforce this Agreement that results in a judgment against the non-paying party for that amount, together with interest on the amount of any unpaid fee and/or expense at the publicly announced prime rate of Citibank, N.A. from the date that fee was required to be paid to, but excluding, the payment date.

(e) Any payment by any other party under this Section 11.04 shall be the sole and exclusive remedy of the other such party and its Subsidiaries for damages against the other such party and any of its Subsidiaries and their respective Representatives with respect to the termination or breach giving rise to that payment. For the avoidance of doubt, any payment to be made by any party under this Section 11.04 shall be payable only once to such other party with respect to this Section 11.04 and not in duplication even though such payment may be payable under one or more provisions hereof.

Section 11.05. Disclosure Schedule References. Notwithstanding anything in this Agreement that may be deemed to the contrary:

(a) Any reference in a particular Section of either the Caremark Disclosure Schedule or the CVS Disclosure Schedule shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (i) the representations and warranties (or covenants, as applicable) of the relevant party that are contained in the corresponding Section of this Agreement and (ii)) any other representations and warranties of such party that are contained in this Agreement, but only in each case if the relevance of that reference as an exception

to (or a disclosure for purposes of) such representations and warranties would be readily apparent on its face to a reasonable person who has read that reference and such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed. The mere inclusion of an item in either the Caremark Disclosure Schedule or the CVS Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had or would be reasonably expected to have a Material Adverse Effect on Caremark or CVS, as applicable; and

(b) any information contained in any part of any Caremark SEC Document or of any CVS SEC Document shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) the representations and warranties of the relevant party if the relevance of that information as an exception to (or a disclosure for purposes of) such representations and warranties would be readily apparent on its face to a reasonable person who has read that information and such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed, provided that in no event shall any information contained in any part of any Caremark SEC Document or of any CVS SEC Document entitled “Risk Factors” or “Forward-Looking Statements” be deemed to be an exception to (or, as applicable, a disclosure for purposes of) any representation(s) and warranty(ies) of Caremark or CVS that is contained in this Agreement.

Section 11.06. Binding Effect; Benefit; Assignment. (a) The provisions of this Agreement shall be binding upon and, except as provided in Section 8.05, shall inure to the benefit of the parties hereto and their respective successors and assigns. Except as provided in Section 8.05, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective successors and assigns.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that any party may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (i) one or more of their Affiliates at any time and (ii) after the Effective Time, to any Person; provided that such transfer or assignment shall not relieve such party of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or due to such party.

Section 11.07. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state.

Section 11.08. Jurisdiction. The parties hereto agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising

out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal court located in the State of Delaware or any Delaware state court, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 11.01 shall be deemed effective service of process on such party.

Section 11.09. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 11.10. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 11.11. Entire Agreement. This Agreement, the Confidentiality Agreement and the exhibits, schedules and annexes hereto constitute the entire agreement between the parties with respect to their subject matter and supersedes all prior agreements and understandings, both oral and written, between the parties with respect to that subject matter.

Section 11.12. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.13. Specific Performance. The parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof (and, more specifically, that irreparable damage would likewise occur if the Merger were not consummated and the affected party’s stockholders did not receive the aggregate Merger Consideration payable to them in accordance with the terms but subject to the conditions of this Agreement), and, accordingly, that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger and CVS’s obligation to pay, and the affected party’s stockholders’ right to receive, the aggregate Merger Consideration payable to them pursuant to the Merger, subject in each case to the terms and conditions of this Agreement) in any federal court located in the State of Delaware or any Delaware state court, in addition to any other remedy to which they are entitled at law or in equity.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the date first written above.
