In the event for any reason the law of any jurisdiction other than New York becomes or is applicable to the Collateral of any Grantor or any part thereof, or to any of the Obligations, such Grantor agrees to execute and deliver all such instruments and to do all such other things as the Administrative Agent in its sole discretion reasonably deems necessary, appropriate or convenient to preserve, protect and enforce the security interests of the Administrative Agent under the law of such other jurisdiction (and, if a Grantor shall fail to do so promptly upon the request of the Administrative Agent, then the Administrative Agent may execute any and all such requested documents on behalf of such Grantor pursuant to the power of attorney granted hereinabove). If any Collateral is in the possession or control of a Grantor’s agents (other than contract manufacturers and other service providers in the ordinary course of business) and the Administrative Agent so requests, such Grantor agrees to notify such agents in writing of the Administrative Agent’s security interest therein and, upon the Administrative Agent’s reasonable request, instruct them to hold all such Collateral for the account of the Secured Parties, subject to the Administrative Agent’s instructions.

(b) Covenants Relating to Patents and Trademarks.

(i) (A) Maintain as in the past the quality of products and services offered under each Trademark owned by such Grantor that is Material Intellectual Property, except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect or a material adverse effect on such Grantor’s rights in such Trademark, (B) employ each Trademark owned by such Grantor that is a Material Intellectual Property with the appropriate notice of registration, if applicable except where the failure to do so could not reasonably be expected to result in a Material Adverse Effect or a material adverse effect on such Grantor’s rights in such Trademark, and (C) not adopt or use any mark that is confusingly similar to or a colorable imitation of any Trademark owned by such Grantor unless the Administrative Agent, for the benefit of the Secured Parties, shall obtain a perfected security interest in such Trademark pursuant to this Security Agreement.

(ii) Notify the Administrative Agent promptly if it knows that any Trademark or Patent owned by such Grantor that is Material Intellectual Property, or any application or registration relating to any Patent or Trademark owned by such Grantor that is Material Intellectual Property, is reasonably likely to become abandoned, invalidated, rendered unenforceable or dedicated to the public, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, or any similar office or agency in any other country or any political subdivision thereof or any court or tribunal in any country) regarding such Grantor’s ownership of any such Patent or Trademark or its right to register the same or to keep and maintain the same.

(iii) Take all reasonable and necessary steps, including in any proceeding before the United States Patent and Trademark Office, or any similar office or agency in any other country or any political subdivision thereof, to maintain and pursue each application (and to obtain the relevant registration) and to maintain each registration of each Patent and each Trademark owned by such Grantor that is Material Intellectual Property, including filing of applications for renewal, affidavits of use and affidavits of incontestability but excluding the maintenance of any Patent or Trademark that in the commercially reasonable business judgment of the Grantor is not necessary or material for either (x) the conduct of the business of any Loan Party or its Subsidiaries or (y) any material Product Development and Commercialization Activities associated with any Product.

(i) Not (and not permit any licensee or sublicensee thereof to) do any act, or omit to do any act, whereby any Material Intellectual Property of such Grantor may become abandoned, invalidated, rendered unenforceable, diluted or dedicated to the public, but excluding Intellectual Property that in the commercially reasonable business judgment of the Grantor is not necessary or material for either (x) the conduct of the business of any Loan Party or its Subsidiaries or (y) any material Product Development and Commercialization Activities associated with any Product.

(iv) Promptly notify the Administrative Agent of any Infringement, of any Material Intellectual Property of such Grantor of which it becomes aware and make such commercially reasonable efforts as it shall determine in its reasonable business judgment to be appropriate under the circumstances to protect such Material Intellectual Property, including, where appropriate, the bringing of suit for Infringement, or dilution, seeking injunctive relief and seeking to recover any and all damages for such Infringement.

(v) Not make any assignment or agreement in conflict with the security interest in the rights in Intellectual Property of such Grantor hereunder (other than as permitted by the Credit Agreement).

7. Advances. On failure of any Grantor to perform any of the covenants and agreements contained herein or in any other Loan Document, the Administrative Agent may, at its sole option and in its sole discretion, perform the same and in so doing may expend such sums as the Administrative Agent may reasonably deem advisable in the performance thereof, including the payment of any insurance premiums, the payment of any taxes, a payment to obtain a release of a Lien or potential Lien, expenditures made in defending against any adverse claim and all other expenditures that the Administrative Agent may make for the protection of the security hereof or that the Administrative Agent may be compelled to make by operation of law. All such sums and amounts so expended shall be repayable by the Grantors, on demand, on a joint and several basis (subject to Section 23 hereof) promptly upon timely notice thereof and demand therefor, shall constitute additional Obligations and shall bear interest from the date said amounts are expended at the Default Rate. No such performance of any covenant or agreement by the Administrative Agent on behalf of any Grantor, and no such advance or expenditure therefor, shall relieve the Grantors of any Default or Event of Default. The Administrative Agent may make any payment hereby authorized in accordance with any bill, statement or estimate procured from the appropriate public office or holder of the claim to be discharged, without inquiry into the accuracy of such bill, statement or estimate or into the validity of any tax assessment, sale, forfeiture, tax lien, title or claim except to the extent such payment is being contested in good faith by a Grantor in appropriate proceedings and against which adequate reserves are being maintained in accordance with GAAP.

8. Remedies.

(a) General Remedies. Upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent shall have, in addition to the rights and remedies provided herein, in the Loan Documents, in any other documents relating to the Obligations, or by law (including levy of attachment, garnishment and the rights and remedies set forth in the UCC of the jurisdiction applicable to the affected Collateral), the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights and remedies are asserted and regardless of whether the UCC applies to the affected Collateral) and, further, the Administrative Agent may, with or without judicial process or the aid and assistance of others, in each case, to the extent permitted by applicable law, (i) enter on any premises on which any of the Collateral may be located and, without resistance or interference by the Grantors, take possession of

the Collateral, (ii) dispose of any Collateral on any such premises, (iii) require the Grantors to assemble and make available to the Administrative Agent at the expense of the Grantors any Collateral at any place and time designated by the Administrative Agent that is reasonably convenient to both parties, (iv) remove any Collateral from any such premises for the purpose of effecting the sale or other disposition thereof, and/or (v) without demand and without advertisement, notice, hearing or process of law, all of which each of the Grantors hereby waives to the fullest extent permitted by law, at any place and time or times, sell and deliver any or all Collateral held by or for it at public or private sale, by one or more contracts, in one or more parcels, for cash, upon credit or otherwise, at such prices and upon such terms as the Administrative Agent deems advisable, in its sole discretion (subject to any and all mandatory legal requirements). Each of the Grantors acknowledges that any private sale referenced above may be at prices and on terms less favorable to the seller than the prices and terms that might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sale shall not be deemed to have been made in a commercially unreasonable manner for such reason. Neither the Administrative Agent’s compliance with applicable law nor its disclaimer of warranties relating to the Collateral shall be considered to adversely affect the commercial reasonableness of any sale. In addition to all other sums due the Administrative Agent and the Secured Parties with respect to the Obligations, the Grantors shall pay the Administrative Agent and each of the Secured Parties all reasonable costs and expenses incurred by the Administrative Agent or any such Secured Party, in enforcing its remedies hereunder including, but not limited to, reasonable attorneys’ fees and court costs, in obtaining or liquidating the Collateral, in enforcing payment of the Obligations, or in the prosecution or defense of any action or proceeding by or against the Administrative Agent or the Secured Parties or the Grantors concerning any matter arising out of or connected with this Security Agreement, any Collateral or the Obligations, including any of the foregoing arising in, arising under or related to a case under Debtor Relief Laws. To the extent the rights of notice cannot be legally waived hereunder, each Grantor agrees that any requirement of reasonable notice shall be met if such notice, specifying the place of any public sale or the time after which any private sale is to be made, is personally served on or mailed, postage prepaid, to the Borrower in accordance with the notice provisions of Section 11.02 of the Credit Agreement at least ten (10) Business Days before the time of sale or other event giving rise to the requirement of such notice. The Administrative Agent 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. The Administrative Agent shall not be obligated to make any sale or other disposition of the Collateral regardless of notice having been given. To the extent permitted by law, any Secured Party may be a purchaser at any such sale. To the extent permitted by applicable law, each of the Grantors hereby waives all of its rights of redemption with respect to any such sale. Subject to the provisions of applicable law, the Administrative Agent and the Secured Parties may postpone or cause the postponement of the sale of all or any portion of the Collateral by announcement at the time and place of such sale, and such sale may, without further notice, to the extent permitted by law, be made at the time and place to which the sale was postponed, or the Administrative Agent may further postpone such sale by announcement made at such time and place.

(b) Remedies Relating to Accounts. Upon the occurrence of an Event of Default and during the continuation thereof, whether or not the Administrative Agent has exercised any or all of its rights and remedies hereunder, (i) each Grantor will promptly upon request of the Administrative Agent instruct all account debtors to remit all payments in respect of Accounts to a mailing location selected by the Administrative Agent and (ii) the Administrative Agent shall have the right to enforce any Grantor’s rights against its customers and account debtors, and the Administrative Agent or its designee may notify (or require any Grantor to notify) any Grantor’s customers and account debtors that the Accounts of such Grantor have been assigned to the Administrative Agent or of the Administrative Agent’s security interest therein, and may (either in its own name or in the name of a

Grantor or both) demand, collect (including by way of a lockbox arrangement), receive, take receipt for, sell, sue for, compound, settle, compromise and give acquittance for any and all amounts due or to become due on any Account, and, in the Administrative Agent’s discretion, file any claim or take any other action or proceeding to protect and realize upon the security interest of the Secured Parties in the Accounts. Each Grantor acknowledges and agrees that the Proceeds of its Accounts remitted to or on behalf of the Administrative Agent in accordance with the provisions hereof shall be solely for the Administrative Agent’s own convenience and that such Grantor shall not have any right, title or interest in such Accounts or in any such other amounts except as expressly provided herein. The Administrative Agent and the other Secured Parties shall have no liability or responsibility to any Grantor for acceptance of a check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement or be responsible for determining the correctness of any remittance. Furthermore, upon the occurrence of an Event of Default and during the continuation thereof, (A) the Administrative Agent shall have the right, but not the obligation, to make test verifications of the Accounts in any manner and through any medium that it reasonably considers advisable, and the Grantors shall furnish all such assistance and information as the Administrative Agent may require in connection with such test verifications, (B) upon the Administrative Agent’s request and at the expense of the Grantors, the Grantors shall cause independent public accountants or others satisfactory to the Administrative Agent to furnish to the Administrative Agent reports showing reconciliations, aging and test verifications of, and trial balances for, the Accounts and (C) the Administrative Agent in its own name or in the name of others may communicate with account debtors on the Accounts to verify with them to the Administrative Agent’s satisfaction the existence, amount and terms of any Accounts.

(c) Access. In addition to the rights and remedies hereunder, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent shall have the right to enter and remain upon the various premises of the Grantors without cost or charge to the Administrative Agent, and use the same, together with materials, supplies, books and records of the Grantors for the purpose of collecting and liquidating the Collateral, or for preparing for sale and conducting the sale of the Collateral, whether by foreclosure, auction or otherwise. In addition, the Administrative Agent may remove Collateral, or any part thereof, from such premises and/or any records with respect thereto, in order to effectively collect or liquidate such Collateral.

(d) Nonexclusive Nature of Remedies. Failure by the Administrative Agent or the Secured Parties to exercise any right, remedy or option under this Security Agreement, any other Loan Document, any other document relating to the Obligations, or as provided by law, or any delay by the Administrative Agent or the Secured Parties in exercising the same, shall not operate as a waiver of any such right, remedy or option. No waiver hereunder shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated, which in the case of the Administrative Agent or the Secured Parties shall only be granted as provided herein. To the extent permitted by law, neither the Administrative Agent, the Secured Parties, nor any party acting as attorney for the Administrative Agent or the Secured Parties, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than their bad faith, gross negligence or willful misconduct hereunder, as determined by a court of competent jurisdiction by final and non-appealable judgment. The rights and remedies of the Administrative Agent and the Secured Parties under this Security Agreement shall be cumulative and not exclusive of any other right or remedy that the Administrative Agent or the Secured Parties may have.

(e) Retention of Collateral. To the extent permitted by applicable law, in addition to the rights and remedies hereunder, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent may, after providing the notices required by

Sections 9-620 and 9-621 of the UCC (or any successor section) or otherwise complying with the requirements of applicable law of the relevant jurisdiction, accept or retain all or any portion of the Collateral in satisfaction of the Obligations. Unless and until the Administrative Agent shall have provided such notices, however, the Administrative Agent shall not be deemed to have accepted or retained any Collateral in satisfaction of any Obligations for any reason.

(f) Deficiency. In the event that the proceeds of any sale, collection or realization are insufficient to pay all amounts to which the Administrative Agent or the Secured Parties are legally entitled, the Grantors shall be jointly and severally liable for the deficiency (subject to Section 23 hereof), together with interest thereon at the Default Rate, together with the costs of collection and the reasonable fees, charges and disbursements of counsel. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Grantors or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto.

9. Rights of the Administrative Agent.

(a) Power of Attorney. In addition to other powers of attorney contained herein, each Grantor hereby designates and appoints the Administrative Agent, on behalf of the Secured Parties, and each of its designees or agents, as attorney-in-fact of such Grantor, irrevocably and with power of substitution, with authority to take any or all of the following actions upon the occurrence and during the continuation of an Event of Default:

(i) to demand, collect, settle, compromise and adjust, and give discharges and releases concerning the Collateral, all as the Administrative Agent may reasonably deem appropriate;

(ii) to commence and prosecute any actions at any court for the purposes of collecting any of the Collateral and enforcing any other right in respect thereof;

(iii) to defend, settle or compromise any action, suit or proceeding brought and, in connection therewith, give such discharge or release as the Administrative Agent may reasonably deem appropriate;

(iv) to receive, open and dispose of mail addressed to such Grantor and endorse checks, notes, drafts, acceptances, money orders, bills of lading, warehouse receipts or other instruments or documents evidencing payment, shipment or storage of the goods giving rise to the Collateral of such Grantor on behalf of and in the name of such Grantor, or securing, or relating to such Collateral;

(v) to pay or discharge taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral;

(vi) to direct any parties liable for any payment in connection with any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Administrative Agent or as the Administrative Agent shall direct;

(vii) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in respect of or arising out of any Collateral;

(viii) to maintain and enforce all Intellectual Property, forming any part of the Collateral;

(ix) to sell, assign, transfer, license, make any agreement in respect of, or otherwise deal with or exercise rights in respect of, any Collateral or the goods or services that have given rise thereto, as fully and completely as though the Administrative Agent were the absolute owner thereof for all purposes;

(x) to adjust and settle claims under any insurance policy relating thereto;

(xi) to execute and deliver all assignments, conveyances, statements, financing statements, renewal financing statements, security and pledge agreements, affidavits, notices and other agreements, instruments and documents that the Administrative Agent may reasonably deem appropriate in order to perfect and maintain the security interests and liens granted in this Security Agreement and in order to fully consummate all of the transactions contemplated therein;

(xii) to institute any foreclosure proceedings that the Administrative Agent may reasonably deem appropriate;

(xiii) to sign and endorse any drafts, assignments, verifications, notices and other documents relating to the Collateral; and

(xiv) to do and perform all such other acts and things as the Administrative Agent may deem appropriate or convenient in connection with the Collateral.

This power of attorney is a power coupled with an interest and shall be irrevocable for so long as any Lender shall have any Commitment under the Credit Agreement, and so long as any Loan or other Obligation under the Credit Agreement shall remain unpaid or unsatisfied (other than contingent indemnification obligations for which no claim has been asserted). The Administrative Agent shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges and options expressly or implicitly granted to the Administrative Agent in this Security Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Administrative Agent shall not be liable for any act or omission or for any error of judgment or any mistake of fact or law in its individual capacity or its capacity as attorney-in-fact except acts or omissions resulting from its gross negligence, bad faith or willful misconduct, as determined by a court of competent jurisdiction by final and non-appealable judgment. This power of attorney is conferred on the Administrative Agent solely to protect, preserve and realize upon its security interest in the Collateral.

(b) Assignment by the Administrative Agent. The Administrative Agent may from time to time assign the Obligations to a successor Administrative Agent appointed in accordance with the Credit Agreement, and such successor shall be entitled to all of the rights and remedies of the Administrative Agent under this Security Agreement in relation thereto.

(c) Releases of Collateral. If any Collateral shall be sold, transferred or otherwise disposed of by any Grantor in a transaction permitted by the Credit Agreement, then the Administrative Agent, at the request and sole expense of such Grantor, shall promptly execute and deliver to such Grantor all releases and other documents, and take such other action, reasonably necessary for the release of the Liens created hereby or by any other Collateral Document on such Collateral. If any of the Collateral constituting Intellectual Property is licensed to a third party under, or rights thereto are granted to a third party pursuant to, a license of Intellectual Property permitted by the Credit Agreement, the Liens granted hereunder and under the other Collateral Documents to

such Intellectual Property shall be subject to the rights of such third party to use such Intellectual Property in accordance with the terms of such license.

(d) The Administrative Agent’s Duty of Care. Other than the exercise of reasonable care to assure the safe custody of the Collateral while being held by the Administrative Agent hereunder and to account for all proceeds thereof, the Administrative Agent shall have no duty or liability to preserve rights pertaining thereto, it being understood and agreed that the Grantors shall be responsible for preservation of all rights in the Collateral, and the Administrative Agent shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the Grantors. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own property, which shall be no less than the treatment employed by a reasonable and prudent agent in the industry, it being understood that the Administrative Agent shall not have responsibility for taking any necessary steps to preserve rights against any parties with respect to any of the Collateral. In the event of a public or private sale of Collateral pursuant to Section 8 hereof, the Administrative Agent shall have no responsibility for (i) ascertaining or taking action with respect to any matters relating to any Collateral, whether or not the Administrative Agent has or is deemed to have knowledge of such matters, or (ii) taking any steps to clean, repair or otherwise prepare the Collateral for sale.

10. Application of Proceeds. Upon the acceleration of the Obligations pursuant to Section 9.02 of the Credit Agreement, any payments in respect of the Obligations and any proceeds of the Collateral, when received by the Administrative Agent or any Secured Party in cash or its equivalent, will be applied in reduction of the Obligations in the order set forth in Section 9.03 of the Credit Agreement, and each Grantor irrevocably waives the right to direct the application of such payments and proceeds and acknowledges and agrees that the Administrative Agent shall have the continuing and exclusive right to apply and reapply any and all such payments and proceeds in the Administrative Agent’s sole discretion, notwithstanding any entry to the contrary upon any of its books and records.

11. Continuing Agreement.

(a) This Security Agreement shall be a continuing agreement in every respect and shall remain in full force and effect for so long as any Lender shall have any Commitment under the Credit Agreement, and so long as any Loan or other Obligation under the Credit Agreement shall remain unpaid or unsatisfied (other than contingent indemnification obligations for which no claim has been asserted), at which time this Security Agreement, and the liens and security interests of the Administrative Agent hereunder, shall be automatically terminated and the Administrative Agent shall, upon the request and at the expense of the Grantors, execute and deliver all UCC termination statements and/or other documents reasonably requested by the Grantors evidencing such termination and return to Grantors all Collateral in its possession. Notwithstanding the foregoing, all releases and indemnities provided hereunder shall survive termination of this Security Agreement.

(b) This Security Agreement shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any Secured Party as a preference, fraudulent conveyance or otherwise under any Debtor Relief Law, all as though such payment had not been made; provided, that, in the event payment of all or any part of the Obligations is rescinded or must be restored or returned, all costs and expenses (including any reasonable attorneys’ fees and disbursements) incurred by the Administrative Agent or any Secured Party in defending and enforcing such reinstatement shall be deemed to be included as a part of the Obligations.

12. Amendments and Waivers; Modifications. This Security Agreement and the provisions hereof may not be amended, waived, modified, changed, discharged or terminated except as set forth in Section 11.01 of the Credit Agreement; provided, that, (a) any update or revision to Schedule 2(c) attached hereto delivered by any Grantor in accordance with the terms hereof, or (b) any amendment to the schedules hereof pursuant to a Joinder Agreement (as contemplated by Section 24 hereof), in each case, shall not constitute an amendment for purposes of this Section 12 or Section 11.01 of the Credit Agreement.

13. Successors in Interest. This Security Agreement shall create a continuing security interest in the Collateral and shall be binding upon each Grantor, its successors and permitted assigns, and shall inure, together with the rights and remedies of the Administrative Agent and the Secured Parties hereunder, to the benefit of the Administrative Agent and the Secured Parties and their successors and permitted assigns; provided, however, none of the Grantors may assign its rights or delegate its duties hereunder without the prior written consent of the requisite Lenders under the Credit Agreement.

14. Notices. All notices required or permitted to be given under this Security Agreement shall be given as provided in Section 11.02 of the Credit Agreement.

15. Counterparts. This Security Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Security Agreement by facsimile or other electronic imaging means (e.g. “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Security Agreement.

16. Headings. Section headings herein are included for convenience of reference only and shall not affect the interpretation of this Security Agreement.

17. Governing Law; Submission to Jurisdiction; Waiver of Venue, Service of Process, Waiver of Right to Jury Trial. The terms of Section 11.14 of the Credit Agreement and Section 11.15 of the Credit Agreement with respect to governing law, submission to jurisdiction, waiver of venue, service of process and waiver of the right to a jury trial are each incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms.

18. Severability. If any provision of this Security Agreement is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Security Agreement shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

19. Entirety. This Security Agreement, the other Loan Documents and the other documents relating to the Obligations represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any proposal letters or correspondence relating to the Loan Documents, any other documents relating to the Obligations, or the transactions contemplated herein and therein.

20. Survival. All representations and warranties of the Grantors hereunder shall survive the execution and delivery of this Security Agreement, the other Loan Documents and the other documents relating to the Obligations, the delivery of the Notes and the extension of credit thereunder or in connection therewith.

21. Other Security. To the extent that any of the Obligations are now or hereafter secured by property other than the Collateral (including real and other personal property and securities owned by a Grantor), or by a guarantee, endorsement or property of any other Person, then to the extent permitted by applicable law the Administrative Agent shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence and during the continuation of any Event of Default, and the Administrative Agent shall have the right, in its sole discretion, to determine which rights, security, liens, security interests or remedies the Administrative Agent shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or the Obligations or any of the rights of the Administrative Agent or the Secured Parties under this Security Agreement, under any of the other Loan Documents or under any other document relating to the Obligations.

22. Rights of Required Lenders. All rights of the Administrative Agent hereunder, if not exercised by the Administrative Agent, may be exercised by the Required Lenders.

23. Joint and Several Obligations of Grantors.

(a) Subject to Section 23(c), each of the Grantors is accepting joint and several liability hereunder in consideration of the financial accommodation to be provided by the Secured Parties, for the mutual benefit, directly and indirectly, of each of the Grantors and in consideration of the undertakings of each of the Grantors to accept joint and several liability for the obligations of each of them.

(b) Subject to Section 23(c), each of the Grantors jointly and severally hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Grantors with respect to the payment and performance of all of the Obligations arising under this Security Agreement, the other Loan Documents and any other documents relating to the Obligations, it being the intention of the parties hereto that all the Obligations shall be the joint and several obligations of each of the Grantors without preferences or distinction among them.

(c) Notwithstanding any provision to the contrary contained herein, in any other of the Loan Documents or in any other documents relating to the Obligations, the obligations of each Guarantor under the Credit Agreement, the other Loan Documents and the other documents relating to the Obligations shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any applicable state law.

24. Joinder. At any time after the date of this Security Agreement, one or more additional Persons may become party hereto by executing and delivering to the Administrative Agent a Joinder Agreement. Immediately upon such execution and delivery of such Joinder Agreement (and without any further action), each such additional Person will become a party to this Security Agreement as a “Grantor” and have all of the rights and obligations of a Grantor hereunder and this Security Agreement and the schedules hereto shall be deemed amended by such Joinder Agreement.
