(a) Each Grantor will keep its chief executive office, the office where it keeps its records concerning the Collateral and Related Contracts to which such Grantor is a party and all originals of all chattel paper that evidence Receivables of such Grantor, at the location therefor specified in Section 8(a) or, upon 30 days’ prior written notice to the Trustee, the Administrative Agent and the Public Trustee at such other locations in a jurisdiction where all actions required by Section 9 shall have been taken with respect to

the Collateral of such Grantor (and, upon the taking of such action in such jurisdiction, Schedule III hereto shall be automatically amended to include such other location). Each Grantor will hold and preserve its records relating to the Collateral, the Related Contracts and chattel paper and will permit representatives of the Trustee, the Administrative Agent and the Public Trustee at any time during normal business hours to inspect and make abstracts from such records and other documents.

(b) Except as otherwise provided in this subsection (b), each Grantor will continue to collect, at its own expense, all amounts due or to become due such Grantor under the Receivables and the Related Contracts. In connection with such collections, such Grantor may take (and, at the direction of the Trustee, the Administrative Agent or the Public Trustee upon the occurrence and during the continuance of an Actionable Default, will take) such action as such Grantor or the Trustee may deem necessary or advisable to enforce collection of the Receivables and the Related Contracts; provided, however, that the Trustee shall have the right, upon the occurrence and during the continuance of an Actionable Default and upon written notice to such Grantor of its intention to do so, to notify the obligors under any Receivables or Related Contracts of the assignment of such Receivables or Related Contracts to the Trustee and to direct such obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Trustee and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables or Related Contracts, and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done. After receipt by any Grantor of the notice from the Trustee referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including instruments) received by such Grantor in respect of the Receivables and the Related Contracts of such Grantor shall be received in trust for the benefit of the Trustee hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Trustee in the same form as so received (with any necessary indorsement) to be deposited in the Trust Account and either (A) released to such Grantor on such terms as provided in the Trust Agreement so long as no Actionable Default shall have occurred and be continuing or (B) if any Actionable Default shall have occurred and be continuing, applied as provided in Section 17(b), (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable, release wholly or partly any obligor thereof, or allow any credit or discount thereon and (iii) such Grantor will not permit or consent to the subordination of its right to payment under any of the Receivables or the Related Contracts to any other indebtedness or obligations of the obligor thereof.

Section 13. As to Intellectual Property Collateral.

(a) With respect to each item of its Intellectual Property Collateral, each Grantor agrees to take, at its expense, all necessary steps, including, without limitation, in the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authority, to (i) maintain the validity and enforceability of each such item of Intellectual Property Collateral and maintain each such item of Intellectual Property Collateral in full force and effect, and (ii) pursue the registration and maintenance of each patent, trademark, or copyright registration or application, now or hereafter included in

the Intellectual Property Collateral of such Grantor, including, without limitation, the payment of required fees and taxes, the filing of responses to office actions issued by the U.S. Patent and Trademark Office, the U.S. Copyright Office or other governmental authorities, the filing of applications for renewal or extension, the filing of affidavits under Sections 8 and 15 of the U.S. Trademark Act, the filing of divisional, continuation, continuation-in-part, reissue and renewal applications or extensions, the payment of maintenance fees and the participation in interference, reexamination, opposition, cancellation, infringement and misappropriation proceedings, except in each case to the extent such Grantor has determined that such action is not appropriate or cost effective in light of costs associated with such action or the value of the related Intellectual Property Collateral. No Grantor shall, without the written consent of the Trustee, discontinue use of or otherwise abandon any Intellectual Property Collateral, or abandon any right to file an application for letters patent, trademark, or copyright, unless such Grantor shall have previously determined that such use or the pursuit or maintenance of such Intellectual Property Collateral is no longer desirable in the conduct of such Grantor’s business and that the loss thereof would not be reasonably likely to have a Material Adverse Effect.

(b) Each Grantor shall take all steps which it or the Trustee, Administrative Agent or Public Trustee deems reasonable and appropriate under the circumstances and in the case of any of the Trustee, Administrative Agent or Public Trustee, which it reasonably requests to preserve and protect each item of its Intellectual Property Collateral, including, without limitation, maintaining the quality of any and all products or services used or provided in connection with any of the Trademarks, consistent with the quality of the products and services as of the date hereof, and taking all reasonable steps to ensure that all licensed users of any of the Trademarks use such consistent standards of quality.

(c) With respect to its Intellectual Property Collateral, each Grantor agrees to execute an agreement, in substantially the form set forth in Exhibit B hereto (an “INTELLECTUAL PROPERTY SECURITY AGREEMENT”), for recording the security interest granted hereunder to the Trustee in such Intellectual Property Collateral with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such Intellectual Property Collateral.

(d) Each Grantor agrees that, should it obtain an ownership interest in any item of the type set forth in Section 1(g) which is not on the date hereof a part of the Intellectual Property Collateral consisting of United States registered patents, trademarks and copyrights (the “AFTER-ACQUIRED INTELLECTUAL PROPERTY”), (i) the provisions of Section 1 shall automatically apply thereto, (ii) any such After-Acquired Intellectual Property and, in the case of trademarks, the goodwill of the business connected therewith or symbolized thereby, shall automatically become part of the Intellectual Property Collateral subject to the terms and conditions of this Agreement with respect thereto, (iii) such Grantor shall give written notice to the Trustee in accordance herewith of any such After-Acquired Intellectual Property within 30 days following the calendar quarter in which such ownership interest was obtained and (iv) such Grantor shall execute and deliver to the Trustee an IP Security Agreement Supplement in substantially the form of

Exhibit C hereto covering such After-Acquired Intellectual Property as “Additional Collateral” thereunder and as defined therein, and shall record such IP Security Agreement Supplement with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other United States Federal governmental authorities necessary to perfect the security interest hereunder in such After-Acquired Intellectual Property.

Section 14. Voting Rights; Dividends; Etc.

(a) So long as no Actionable Default shall have occurred and be continuing:

(i) each Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Security Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement or the other Debt Instruments.

(ii) each Grantor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral; provided, however, that any and all

(A) dividends, interest and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral,

(B) dividends and other distributions paid or payable in cash in respect of any Security Collateral in connection with a partial or total liquidation or dissolution, and

shall be, and shall be forthwith delivered to the Trustee to hold as, Security Collateral and shall, if received by each Grantor, be received in trust for the benefit of the Trustee, be segregated from the other property or funds of each Grantor and be forthwith delivered to the Trustee as Security Collateral in the same form as so received (with any necessary indorsement).

(iii) The Trustee shall execute and deliver (or cause to be executed and delivered) to each Grantor all such proxies and other instruments as each Grantor may reasonably request for the purpose of enabling each Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

(b) Upon the occurrence and during the continuance of an Actionable Default:

(i) All rights of each Grantor (x) to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 14(a)(i) shall, upon notice to each Grantor

by the Trustee, cease and (y) to receive the dividends and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 14(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Trustee, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends and other distributions.

(ii) All dividends and other distributions that are received by each Grantor contrary to the provisions of paragraph (i) of this Section 14(b) shall be received in trust for the benefit of the Trustee, shall be segregated from other funds of each Grantor and shall be forthwith paid over to the Trustee as Security Collateral in the same form as so received (with any necessary indorsement).

Section 15. Transfers and Other Liens; Additional Shares.

(a) Each Grantor agrees that it will not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Debt Instruments, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Grantor except for the pledge, assignment and security interest created under this Agreement and Permitted Liens (as defined in the Credit Agreement).

(b) Each Grantor agrees that it will (i) cause each issuer of the Pledged Shares pledged by such Grantor not to issue any stock or other securities in addition to or in substitution for the Pledged Shares issued by such issuer, except to such Grantor, and (ii) pledge hereunder, immediately upon its acquisition (directly or indirectly) thereof, any and all additional shares of stock or other securities.

Section 16. Trustee May Perform.

If any Grantor fails to perform any agreement contained herein, the Trustee may, as the Trustee deems necessary to protect the security interest granted hereunder in the Collateral or to protect the value thereof, but without any obligation to do so (and upon the occurrence and during the continuation of an Actionable Default without notice), itself perform, or cause performance of, such agreement, and the reasonable expenses of the Trustee incurred in connection therewith shall be payable by such Grantor as provided in the Trust Agreement.

(a) The Trustee’s Duties.

Without limiting the protections provided the Trustee under Section 5 of the Trust Agreement (which are hereby incorporated herein by reference), the powers conferred on the Trustee hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Trustee shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

Section 17. Remedies.

If any Actionable Default shall have occurred and be continuing:

(a) The Trustee may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the N.Y. Uniform Commercial Code (whether or not the N.Y. Uniform Commercial Code applies to the affected Collateral) and also may (i) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Trustee forthwith, assemble all or part of the Collateral as directed by the Trustee and make it available to the Trustee at a place to be designated by the Trustee that is reasonably convenient to both parties, (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable, (iii) occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; and (iv) exercise any and all rights and remedies of any of the Grantors under or in connection with the Agreements, the Receivables and the Related Contracts or otherwise in respect of the Collateral, including, without limitation, any and all rights of such Grantor to demand or otherwise require payment of any amount under, or performance of any provision of, the Agreements, the Receivables and the Related Contracts. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to each Grantor of the time and place of any public sale or of the time after which any private sale is to be made shall constitute reasonable notification. The Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) All cash proceeds received by the Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be deposited into the Trust Account and may, in the discretion of the Trustee, be held by the Trustee as collateral for, and/or then or at any time thereafter applied in whole or in part by the Trustee against the Secured Obligations as provided in Section 3.4 of the Trust Agreement.

(d) All payments received by each Grantor in respect of the Collateral shall be received in trust for the benefit of the Trustee, shall be segregated from other funds of each Grantor and shall be forthwith paid over to the Trustee in the same form as so received (with any necessary indorsement).

(e) The Trustee may, without notice to each Grantor except as required by law and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Secured Obligations against the Trust Account, the L/C Cash Collateral Account or any part thereof.

Section 18. Registration Rights.

If the Trustee shall determine to exercise its right to sell all or any of the Security Collateral pursuant to Section 17, the Company agrees that, upon request of the Trustee, the Company will, at its own expense:

(a) execute and deliver, and cause Caremark, Inc. and the directors and officers of such issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts and things, as may be necessary or, in the opinion of the Trustee, advisable to register the shares thereof pledged hereunder under the provisions of the Securities Act of 1933, as from time to time amended (the “SECURITIES ACT”), to cause the registration statement relating thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished and to make all amendments and supplements thereto and to the related prospectus that, in the opinion of the Trustee, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto;

(b) use its best efforts to qualify such shares under the state securities or “Blue Sky” laws and to obtain all necessary governmental approvals for the sale of such shares, as requested by the Trustee;

(c) cause such issuer to make available, as soon as practicable, an earnings statement that will satisfy the provisions of Section 11(a) of the Securities Act;

(e) do or cause to be done all such other acts and things as may be necessary to make such sale of such shares or any part thereof valid and binding and in compliance with applicable law.

The Trustee is authorized, in connection with any sale of such shares pursuant to Section 17, to deliver or otherwise disclose to any prospective purchaser of such shares (i) any registration statement or prospectus, and all supplements and amendments thereto, prepared pursuant to clause (a) above, (ii) any information and projections provided to it pursuant to clause (d) above and (iii) any other information in its possession relating to such shares.

Section 19. Amendments; Waivers; Additional Grantors; Etc.

(a) No amendment or waiver of any provision of this Agreement, and no consent to any departure by any Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee with the written consent of the Administrative Agent and the Public Trustee, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Trustee or any other Secured Party to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.

(b) Upon the execution and delivery by any Person of a security agreement supplement in substantially the form of Exhibit A hereto (each a “SECURITY AGREEMENT SUPPLEMENT”), (i) such Person shall be referred to as an “Additional GRANTOR” and shall be and become a Grantor hereunder and each reference in this Agreement to “Grantor” shall also mean and be a reference to such Additional Grantor, and (ii) the supplemental schedules I, II, III, and IV attached to each Security Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I, II, III, and IV, respectively, hereto, and the Trustee may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Security Agreement Supplement.

Section 20. Notices; Etc.

All notices and other communications provided for hereunder shall be in writing (including telecopier communication) and mailed, telecopied, or delivered to, in the case of a Grantor or the Trustee, addressed to it at its address specified in the Trust Agreement and, in the case of each Additional Grantor, addressed to it at its address set forth opposite such Additional Grantor’s name on the signature page to the Security Agreement Supplement pursuant to which it became a party hereto; or, as to any party, at such other address as shall be designated by such party in a written notice to the other parties. All such notices and other communications shall, when mailed or telecopied, be effective when deposited in the mails or telecopied, respectively, addressed as aforesaid; provided, however, that any notices and other communications to the Trustee shall not be effective until received by the Trustee. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or of any

Security Agreement Supplement or Schedule hereto shall be effective as delivery of an original executed counterpart thereof.

This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the release of all Collateral as provided in Section 6.1 of the Trust Agreement, (b) be binding upon each Grantor, its successors and assigns and (c) inure, together with the rights and remedies of the Trustee hereunder, to the benefit of the Trustee, the Secured Parties and their respective successors, transferees and assigns.

Section 22. Execution in Counterparts.

This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of an original executed counterpart of this Agreement.

Section 23. Governing Law.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
