The reasonable costs and expenses (including, without limitation, attorneys’ fees) incurred or sustained in connection with collection, whether incurred or sustained by such Grantor or the Administrative Agent, shall be borne by such Grantor.

     4.5. Instruments.

Each Grantor further agrees, if consistent with good business practice, diligently to prosecute any Person infringing any Mark, where such infringement could reasonably be expected to have a Material Adverse Effect, in a manner in accordance with its reasonable business practices.

     5.4. Preservation of Marks. Each Grantor agrees to use its material Marks in interstate commerce during the time in which this Agreement is in effect, sufficiently to preserve such Marks (and any registrations thereof) as trademarks or service marks registered under the laws of the United States; provided, however, that no Grantor shall be obligated to preserve any Mark in the event such Grantor determines, in its reasonable business judgment, that the preservation of such Mark is no longer necessary or desirable in the conduct of its business.

     5.5. Maintenance of Registration. Each Grantor shall, at its own expense, diligently process all documents required by the Trademark Act of 1946, 15 U.S.C. §§ 1051 et seq., to maintain its material trademark registrations, including, but not limited to, affidavits of use and

applications for renewals of registration in the United States Patent and Trademark Office for all of its registered material Marks pursuant to 15 U.S.C. §§ 1058(a), 1059 and 1065, and shall pay all required fees in connection therewith, and shall not abandon any such filing of affidavit of use or any such application of renewal prior to the exhaustion of all judicial remedies without the prior written consent of the Administrative Agent; provided, however, that no Grantor shall be obligated to maintain any Mark in the event that such Grantor determines, in its reasonable business judgment, that the maintenance of such Mark is no longer necessary or desirable in the conduct of its business.

     5.6. Future Registered Marks. If any Mark registration issues at any time hereafter to any Grantor as a result of any application now or hereafter pending before the United States Patent and Trademark Office, such Grantor shall, upon the reasonable request of the Administrative Agent from time to time, deliver promptly to the Administrative Agent a copy of such certificate and a grant of security in such Mark to the Administrative Agent, confirming the grant thereof hereunder, the form of such confirmatory grant of security to be in form and substance reasonably satisfactory to the Administrative Agent.

     5.7. Remedies. If any Event of Default shall be continuing, the Administrative Agent may, by written notice to any Grantor, take any or all of the following actions, all to the extent necessary to enable the Administrative Agent to realize on the Security Agreement Collateral: (a) declare the entire right, title and interest of such Grantor in and to each of such Grantor’s Marks and the goodwill of the business associated therewith, together with all trademark rights and rights of protection to the same, vested in the Administrative Agent, in which event such rights, title and interest shall immediately vest in the Administrative Agent for the benefit of the Secured Parties pursuant to this Agreement; (b) take and use or sell the Marks and the goodwill of such Grantor’s business symbolized by the Marks and the right to carry on the business and use the assets of such Grantor in connection with which the Marks have been used; and (c) direct such Grantor to use commercially reasonable efforts to refrain, in which event such Grantor shall refrain, from using the Marks in any manner whatsoever, directly or indirectly, and, if reasonably requested by the Administrative Agent, change such Grantor’s name to eliminate therefrom any use of any Mark and execute such other and further documents that the Administrative Agent may from time to time reasonably request to further confirm this and to transfer ownership of the Marks and registrations and any pending trademark application in the United States Patent and Trademark Office or any equivalent government agency or office in any foreign jurisdiction to the Administrative Agent.

ARTICLE VII

PROVISIONS CONCERNING
SECURITY AGREEMENT COLLATERAL

     7.1. Protection of Administrative Agent’s Security. No Grantor will do anything to impair in any material respect the material rights of the Administrative Agent in the Security Agreement Collateral. Each Grantor will at all times keep its Inventory and Equipment insured in favor of the Administrative Agent, at such Grantor’s own expense, to the extent commercially reasonable in the manner provided in the Credit Agreement and the other Loan Documents; all policies or certificates with respect to such insurance shall be endorsed to the Administrative Agent’s satisfaction for the benefit of the Administrative Agent (including, without limitation, by naming the Administrative Agent as loss payee and additional insured). If any Grantor shall fail to insure its Inventory to the extent required by the Credit Agreement, or if any Grantor shall fail to so endorse all policies or certificates with respect thereto, the Administrative Agent shall have the right (but shall be under no obligation) to procure such insurance, and such Grantor agrees to reimburse the Administrative Agent for all reasonable costs and expenses of procuring such insurance. The Administrative Agent shall apply any proceeds in accordance with Section 8.3 of the Credit Agreement. Each Grantor assumes all liability and responsibility in connection with the Security Agreement Collateral acquired by it and the liability of such Grantor to pay its Obligations shall in no way be affected or diminished by reason of the fact that such Security Agreement Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever unavailable to such Grantor.

     7.2. Warehouse Receipts Non-Negotiable. Each Grantor agrees that if any warehouse receipt or receipt in the nature of a warehouse receipt is issued with respect to any substantial portion of its Inventory, such warehouse receipt or receipt in the nature thereof shall not be “negotiable” (as such term is used in Section 7-104 of the Uniform Commercial Code as in effect in any relevant jurisdiction or under other relevant law).

     7.3. Promissory Notes and Tangible Chattel Paper. If any Grantor shall, now or at any time hereafter, hold or acquire, otherwise than in the ordinary course of its business, any promissory notes or tangible Chattel Paper, such Grantor shall forthwith endorse, assign and deliver the same to the Administrative Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Administrative Agent may from time to time specify.

     7.4. Deposit Accounts.

          (a) The following provisions of this paragraph (a) shall be applicable to the concentration accounts and the disbursement accounts from time to time established by the Parent Company, the Borrower and the Subsidiary Guarantors as part of the cash management systems of the Parent Company and its Subsidiaries (such concentration accounts and disbursement accounts being in this paragraph (a) called, collectively, the “Cash Management Accounts”). Each Grantor shall, not later than the Closing Date and except as otherwise permitted by the Credit Agreement as agreed by the Administrative Agent, cause each depositary bank of the Deposit Accounts listed on Schedule 4.1(a)(ii) to the Credit Agreement to enter into a control agreement, in form and substance reasonably satisfactory to the Administrative Agent, pursuant to which such depositary bank (or, in the case of any Cash Management Account subject to the Applicable Laws of jurisdictions outside of the United States, such other instruments in lieu thereof as may be reasonably required by the Administrative Agent), shall agree to comply, without further consent of such Grantor, with instructions from the Administrative Agent directing the disposition of funds from time to time credited to such Cash Management Accounts. The Administrative Agent agrees with each Grantor that the Administrative Agent shall not give any such instructions or withhold any withdrawal rights from such Grantor, unless an Event of Default has occurred and is continuing. The obligations of the Grantors under this paragraph (a) shall not otherwise limit the rights and remedies of the Administrative Agent under paragraph (b) of this Section 7.4 or under Section 8.1 or Section 8.2 hereof during the continuation of Events of Default. The provisions of this paragraph shall not apply to any Deposit Accounts specially and exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of any Grantor’s salaried employees.

          (b) With respect to each Deposit Account that any Grantor, now or at any time hereafter, opens or maintains with any depositary institution, such Grantor shall, at the Administrative Agent’s request and option from time to time following the occurrence of any Event of Default, immediately provide to the Administrative Agent a list of account names and numbers, and the name, address and contact information for each depositary institution, and shall, pursuant to a control agreement in form and substance reasonably satisfactory to the Administrative Agent, cause the depositary bank to agree to comply, without further consent of such Grantor, at any time with instructions from the Administrative Agent to such depositary bank directing the disposition of funds from time to time credited to such Deposit Account. The Administrative Agent agrees with each Grantor that the Administrative Agent shall not give any such instructions or withhold any withdrawal rights from such Grantor, unless an Event of Default has occurred and is continuing or unless a Default would occur if effect were given to any withdrawal not otherwise permitted by the Loan Documents. The provisions of this paragraph shall not apply to any Deposit Accounts specially and exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of any Grantor’s salaried employees.

     7.5. Securities Accounts. If any Securities, whether certificated or uncertificated, or other Investment Property now or hereafter acquired by any Grantor are held by such Grantor or its nominee through a Securities Intermediary or commodity intermediary, such Grantor shall, at the Administrative Agent’s reasonable request and option from time to time following the occurrence and during the continuance of an Event of Default, promptly provide to the Administrative Agent a list of such Securities and other Investment Property and related account names and numbers, and the name, address and contact information for each Securities Intermediary or commodity intermediary, and shall either (a) use reasonable efforts to cause such Securities Intermediary or (as the case may be) commodity intermediary to agree to comply, in each case without further consent of such Grantor or such nominee, at any time during the continuance of an Event of Default with Entitlement Orders or other instructions from the Administrative Agent to such Securities Intermediary as to such securities or other Investment Property, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Administrative Agent to such commodity intermediary, all pursuant to a control agreement in form and substance reasonably satisfactory to the Administrative Agent, or (b) in the case of Financial Assets or other Investment Property held through a Securities Intermediary, arrange for the Administrative Agent to become the Entitlement Holder with respect to such Investment Property, with such Grantor being permitted, only with the consent of the Administrative Agent, to exercise rights to withdraw or otherwise deal with such Investment Property. The Administrative Agent agrees with each Grantor that the Administrative Agent shall not give any such entitlement orders or instructions or directions to any such issuer, Securities Intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by such Grantor, unless an Event of Default has occurred and is continuing.

     7.6. Collateral in the Possession of a Bailee. If any substantial portion of the Collateral is, now or at any time hereafter, in the possession of a bailee, the relevant Grantor shall promptly notify the Administrative Agent thereof and, at the Administrative Agent’s reasonable request and option following the occurrence of an Event of Default, shall assist the Administrative Agent to obtain an acknowledgement from the bailee, in form and substance satisfactory to the Administrative Agent, that the bailee holds such Collateral for the benefit of the Administrative Agent and such bailee’s agreement to comply, without further consent of such Grantor, at any time with instructions of the Administrative Agent as to such Collateral. The Administrative Agent agrees with each Grantor that the Administrative Agent shall not give any such instructions unless an Event of Default has occurred and is continuing.

     7.7. Electronic Chattel Paper and Transferable Records. If any Grantor, now or at any time hereafter, holds or acquires, otherwise than in the ordinary course of its business, an interest in any electronic Chattel Paper or any “transferable record”, as that term is defined in Section 201 of the federal Electronic Signatures in Global and National Commerce Act, or in §16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, such Grantor shall promptly notify the Administrative Agent thereof and, at the request and option of the Administrative Agent following the occurrence of an Event of Default, shall take such action as the Administrative Agent may reasonably request to vest in the Administrative Agent control, under §9-105 of the UCC, of such electronic chattel paper or control under Section 201 of the federal Electronic Signatures in Global and National Commerce Act or, as the case may be, §16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such

transferable record. The Administrative Agent agrees with each Grantor that the Administrative Agent will arrange, pursuant to procedures satisfactory to the Administrative Agent and so long as such procedures will not result in the Administrative Agent’s loss of control, for such Grantor to make alterations to the electronic chattel paper or transferable record permitted under UCC §9-105 or, as the case may be, Section 201 of the federal Electronic Signatures in Global and National Commerce Act or §16 of the Uniform Electronic Transactions Act for a party in control to make without loss of control, unless an Event of Default has occurred and is continuing.

     7.8. Letter-of-Credit Rights. If any Grantor is, now or at any time hereafter, a beneficiary under any letter of credit, such Grantor shall promptly notify the Administrative Agent thereof and, at the request and option of the Administrative Agent from time to time following the occurrence and during the continuance of an Event of Default, such Grantor shall, pursuant to an agreement in form and substance reasonably satisfactory to the Administrative Agent, either (a) arrange for the issuer and any confirmer of such letter of credit to consent to an assignment to the Administrative Agent of the proceeds of the letter of credit, or (b) arrange for the Administrative Agent to become the transferee beneficiary of the letter of credit, with the Administrative Agent agreeing, in each case, that the proceeds of the letter of credit are to be applied as provided in the Credit Agreement.

     7.9. Commercial Tort Claims. If any Grantor shall, now or at any time hereafter, hold or acquire a Commercial Tort Claim, such Grantor shall promptly notify the Administrative Agent in a writing signed by such Grantor of the particulars thereof and grant to the Administrative Agent in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the Administrative Agent.

     7.10. Further Actions. Each Grantor will, at its own expense, make, execute, endorse, acknowledge, file and/or deliver to the Administrative Agent from time to time upon the reasonable request of the Administrative Agent all such lists, descriptions and designations of its Security Agreement Collateral, warehouse receipts, receipts in the nature of warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports and other assurances or instruments and take all such further steps relating to the Security Agreement Collateral and other Property or rights covered by the security interests hereby granted, which the Administrative Agent shall from time to time reasonably deem appropriate to perfect, preserve or protect its security interests in the Security Agreement Collateral.

     7.11. Financing Statements. Each Grantor irrevocably authorizes the Administrative Agent at any time and from time to time to file in any filing office in any Uniform Commercial Code jurisdiction any initial financing statements and amendments thereto, in form reasonably acceptable to the Administrative Agent, as are necessary or desirable in the reasonable opinion of the Administrative Agent to establish and maintain valid, enforceable and perfected security interests (subject only to Liens permitted by the Credit Agreement) in the Security Agreement Collateral as provided herein and the other rights and security contemplated hereby, all in accordance with the Uniform Commercial Code as enacted in any and all relevant jurisdictions or any other relevant law. Each Grantor will pay any applicable filing fees and related expenses.

ARTICLE VIII

REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

     8.1. Remedies; Obtaining the Security Agreement Collateral Upon Default. Each Grantor agrees that, if any Event of Default shall be continuing, then, and in every such case, the Administrative Agent, in addition to any other rights now or hereafter existing under Applicable Law, shall have all rights as a secured creditor under the Uniform Commercial Code in all relevant jurisdictions and may:

          (a) personally, or by agents or attorneys, immediately take possession of the Security Agreement Collateral or any part thereof from such Grantor or from any other Person who then has possession of any part thereof, with or without notice or process of law, and for that purpose may enter upon such Grantor’s premises where any of the Security Agreement Collateral is located and remove the same and use, in connection with such removal, any and all services, supplies, aids and other facilities of such Grantor;

          (b) instruct the obligor or obligors on any agreement, Instrument or other obligation (including, without limitation, the Receivables) constituting the Security Agreement Collateral to make any payment required by the terms of such agreement or instrument directly to the Administrative Agent;

          (c) withdraw all monies, securities and other Instruments held in any account for application to the Obligations in accordance with Section 8.4;

          (d) sell, assign or otherwise liquidate, or direct such Grantor to sell, assign or otherwise liquidate, any or all of the Security Agreement Collateral or any part thereof in accordance with Section 8.2 and take possession of the proceeds of any such sale or liquidation;

          (e) take possession of the Security Agreement Collateral, or any part thereof, by directing such Grantor in writing to deliver the same to the Administrative Agent at any place or places designated by the Administrative Agent, in which event such Grantor shall at its own expense:

          (i) forthwith cause the same to be moved to the place or places so designated by the Administrative Agent and there delivered to the Administrative Agent;

          (ii) store and keep any Security Agreement Collateral so delivered to the Administrative Agent at such place or places pending further action by the Administrative Agent as provided in Section 8.2; and

          (iii) while the Security Agreement Collateral shall be so stored and kept, provide such guards and maintenance services as shall be necessary to protect the same and to preserve and maintain it in good condition; and

          (f) license or sublicense, whether on an exclusive or nonexclusive basis, any Marks, Patents or Copyrights included in the Security Agreement Collateral for such term and on such conditions and in such manner as the Administrative Agent shall in its sole judgment

determine (taking into account such provisions as may be necessary to protect and preserve such Marks, Patents or Copyrights);

it being understood that such Grantor’s obligations to so deliver the Security Agreement Collateral are of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Administrative Agent shall be entitled to a decree requiring specific performance by such Grantor of said obligations.

     8.2. Remedies; Disposition of the Security Agreement Collateral. During the continuance of any Event of Default, any Security Agreement Collateral repossessed by the Administrative Agent under or pursuant to Section 8.1 and any other Security Agreement Collateral, whether or not so repossessed by the Administrative Agent, may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the Property to be sold, and, in general, in such manner, at such time or times, at such place or places and on such terms as the Administrative Agent may determine to be commercially reasonable. Any of the Security Agreement Collateral may be sold, leased or otherwise disposed of in the condition in which the same existed when taken by the Administrative Agent or after any overhaul or repair (at the expense of each Grantor) which the Administrative Agent shall determine to be commercially reasonable. Any such disposition which shall be a private sale or other private proceedings shall be made upon not less than ten (10) days’ prior written notice to the relevant Grantor specifying the time after which such disposition is to be made and the intended sale price or other consideration therefor. Any such disposition which shall be a public sale shall be made upon not less than ten (10) days’ prior written notice to the relevant Grantor specifying the time and place of such Sale. The Administrative Agent, on behalf of the Secured Parties, may bid for and become the purchaser of the Security Agreement Collateral or any item thereof offered for sale in accordance with this Section 8.2 without accountability to the relevant Grantor. Each Grantor agrees to do or cause to be done all such other acts and things as may be reasonably necessary to make such sale or sales of all or any portion of the Security Agreement Collateral valid and binding and in compliance with all Applicable Laws of any and all courts, arbitrators or other Governmental Authorities having jurisdiction over any such sale or sales, all at such Grantor’s expense.

     8.3. WAIVER OF CLAIMS. EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT, EACH GRANTOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY NOTICE OR JUDICIAL HEARING IN CONNECTION WITH THE ADMINISTRATIVE AGENT’S TAKING POSSESSION, OR THE ADMINISTRATIVE AGENT’S DISPOSITION, OF ANY OF THE SECURITY AGREEMENT COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE OR HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH SUCH GRANTOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, AND EACH GRANTOR HEREBY FURTHER WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW:

          (a) all damages occasioned by such taking of possession, except any damages which are the direct result of the Administrative Agent’s gross negligence or willful misconduct;

          (b) all other requirements as to the time, place, manner or terms of sale or other requirements with respect to the enforcement of the Administrative Agent’s rights hereunder; and

          (c) all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any Applicable Law, and all other rights to prevent or delay the enforcement of this Agreement or the absolute sale of the Security Agreement Collateral or any portion thereof;

and each Grantor, for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all of such laws. Any sale of, or the grant of any options to purchase, or any other realization upon, any Security Agreement Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the relevant Grantor therein and thereto, and shall be a perpetual bar both at law and in equity against such Grantor and against any and all Persons claiming or attempting to claim the Security Agreement Collateral so sold, optioned or realized upon, or any part thereof, from, through and under such Grantor.

     8.4. Application of Proceeds.

          (a) All monies collected by the Administrative Agent upon any sale or other disposition of all or any part of the Security Agreement Collateral, together with all other monies from time to time received by the Administrative Agent hereunder, shall be applied in accordance with Section 8.3 of the Credit Agreement.

          (b) All payments required to be made hereunder shall be made to the Administrative Agent under the Credit Agreement for the account of the Secured Parties.

          (c) For purposes of applying payments received in accordance with this Section 8.4, (i) the Administrative Agent shall determine the outstanding unpaid Obligations owed pursuant to the Credit Agreement and the other Loan Documents, and (ii) the Administrative Agent may rely on any Secured Party to determine any other Obligations owed to such Secured Party.

          (d) It is understood and agreed that each Grantor shall remain jointly and severally liable to the extent of any deficiency remaining after the application of all of the proceeds of the Security Agreement Collateral hereunder to the unpaid Obligations as provided by Section 8.4(a).

     8.5. Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Administrative Agent shall be in addition to every other right, power and remedy specifically given under this Agreement, any of the other Loan Documents, or now or hereafter existing at law or in equity, or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Administrative Agent. All such rights, powers and remedies shall be cumulative, and the exercise or the beginning of exercise of one shall not be deemed a waiver of the right to exercise of any other or others. No delay or omission of the Administrative Agent in the exercise of any

such right, power or remedy and no renewal or extension of any of the Obligations and no course of dealing between any Grantor and the Administrative Agent or any holder of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence therein. In the event that the Administrative Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Administrative Agent may recover reasonable expenses actually incurred or sustained, including attorneys’ fees actually incurred or sustained, and the amounts thereof shall be included in such judgment.

     8.6. Discontinuance of Proceedings. In case the Administrative Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, Asset Sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Administrative Agent, then, and in every such case, the relevant Grantor, the Administrative Agent and the holders of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Security Agreement Collateral subject to the security interests created under this Agreement, and all rights, remedies and powers of the Administrative Agent shall continue as if no such proceeding had been instituted.

Each Grantor agrees that, upon written notice by any Indemnitee of the

assertion of such a liability, obligation, loss, damage, injury, penalty, claim, demand, action, suit or judgment, such Grantor shall assume full responsibility for the defense thereof. Each Indemnitee agrees to use its best efforts to promptly notify such Grantor of any such assertion of which such Indemnitee has knowledge.

          (b) Without limiting the application of paragraph (a) of this Section 9.1, each Grantor jointly and severally agrees to pay, or to reimburse the Administrative Agent for (if the Administrative Agent shall have incurred fees, costs or expenses because such Grantor shall have failed to comply with its Obligations under this Agreement or any other Loan Document), any and all reasonable fees, costs and expenses of whatsoever kind or nature incurred or sustained in connection with the creation, preservation or protection of the Administrative Agent’s Liens on, and security interests in, the Security Agreement Collateral, including, without limitation, all fees and taxes in connection with the recording or filing of Instruments and documents in public offices, payment or discharge of any taxes or Liens upon or in respect of the Security Agreement Collateral, premiums for insurance with respect to the Security Agreement Collateral and all other reasonable fees, costs and expenses actually incurred or sustained in connection with protecting, maintaining or preserving the Security Agreement Collateral and the Administrative Agent’s security interests therein, whether through judicial proceedings or otherwise, or in defending or prosecuting any actions, suits or proceedings arising out of or relating to the Security Agreement Collateral.

     9.2. Indemnity Obligations Secured by Security Agreement Collateral; Survival. Any amounts paid by any Indemnitee, as to which such Indemnitee has the right to reimbursement, shall constitute Obligations secured by the Security Agreement Collateral.

          (a) Except as otherwise contemplated by Section 10.5 hereof, none of the terms or conditions of this Agreement may be changed, waived, modified or varied in any manner whatsoever unless in writing duly signed by each Grantor directly and adversely affected thereby and by the Administrative Agent (with the consent of the Required Lenders, or, to the extent required by Section 10.1 of the Credit Agreement, with the consent of each of the Lenders).

          (b) No delay on the part of the Administrative Agent in exercising any of its rights, remedies, powers and privileges hereunder, and no partial or single exercise thereof, shall constitute a waiver thereof. No notice to or demand on any Grantor in any case shall entitle it to any other or further notice or demand in any similar or other circumstances or constitute a waiver of any of the rights of the Administrative Agent to any other or further action in any circumstances without notice or demand.

     10.3. Obligations Absolute.

          (a) The Obligations of each Grantor under this Agreement and the Intellectual Property Security Agreement to which it is a party shall be absolute, unconditional and irrevocable and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise impaired or affected by, any circumstance or occurrence whatsoever, including, without limitation, any of the circumstances or occurrences described or referred to in paragraph (a) of Section 6 of the Guaranty Agreement or in clauses (i) through (x) of Section 17(a) of the Pledge Agreement, except as released pursuant to the terms of any of the Loan Documents.

          (b) Each of the Grantors hereby irrevocably agrees to be bound by the terms of each of paragraph (b), paragraph (c) and paragraph (d) of Section 17 of the Pledge Agreement and paragraphs (b), (c) and (d) of Section 6 of the Guaranty Agreement with the same full force and effect as if each of such paragraphs of the Pledge Agreement and the Guaranty Agreement were set forth in full in this Agreement and the Intellectual Property Security Agreement to which each such Grantor is a party and made applicable to each of the Grantors as well as to the Pledgors and the Guarantors.

     10.4. Successors and Assigns. This Agreement shall be binding upon each Grantor and its successors and assigns and shall inure to the benefit of the Administrative Agent and its successors and assigns; provided, however, that no Grantor may transfer or assign any or all of its rights or obligations hereunder without the prior written consent of the Administrative Agent. All agreements, statements, representations and warranties made by each Grantor herein or in any certificate or other instrument delivered by each Grantor or on its behalf under this Agreement shall be considered to have been relied upon by the Secured Parties and shall survive the execution and delivery of this Agreement and the other Loan Documents, regardless of any investigation made by the Secured Parties or on their behalf.

     10.5. Additional Grantors. Additional Subsidiaries of the Parent Company or of the Borrower (“Additional Grantors”) may from time to time hereafter become parties to and bound by this Agreement by executing a counterpart hereof, or (alternatively) by executing a supplement to this Agreement or a joinder agreement, (in each case) in form and substance reasonably satisfactory to the Administrative Agent, and there shall be no need to re-execute, amend or restate this Agreement in connection therewith. Upon such execution and delivery of this Agreement by any Additional Grantor, such Additional Grantor shall be deemed to have made the representations and warranties set forth in this Agreement, and shall be bound by all of the terms, covenants and conditions hereof to the same extent as if such Additional Grantor had executed this Agreement as of the date hereof, and the Administrative Agent shall be entitled to all of the benefits of such Additional Grantor’s Obligations hereunder.

     10.6. Headings Descriptive. The headings of the several sections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

     10.7. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     10.8. GOVERNING LAW AND WAIVER OF JURY TRIAL; ETC.

              (a) THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

              (b) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATED IN ANY WAY TO THIS AGREEMENT. EACH OF THE PARTIES HERETO AGREES TO BE BOUND BY THE PROVISIONS SET FORTH IN SECTION 10.14 AND SECTION 10.15 OF THE CREDIT AGREEMENT WITH THE SAME FULL FORCE AND EFFECT AS IF SET FORTH IN FULL HEREIN AND MADE EXPRESSLY APPLICABLE TO EACH PARTY HERETO.

     10.9. Grantor’s Duties. It is expressly agreed, anything herein contained to the contrary notwithstanding, that each Grantor shall remain liable to perform all of the Obligations, if any, assumed by it with respect to the Security Agreement Collateral, and the Administrative Agent shall not have any obligations or liabilities with respect to any Security Agreement Collateral by reason of or arising out of this Agreement, nor shall the Administrative Agent be required or obligated in any manner to perform or fulfill any of the obligations of any Grantor under or with respect to any Security Agreement Collateral.

     10.10. Termination; Release.

                 (a) On the Termination Date, this Agreement and the security interests granted hereunder, shall terminate, and all rights to the Security Agreement Collateral shall revert to the applicable Grantor, and the Administrative Agent, at the request and expense of any Grantor, will execute and deliver to such Grantor a proper Instrument or Instruments (including Uniform Commercial Code termination statements) acknowledging the satisfaction and termination of this Agreement, and will duly assign, transfer and deliver to such Grantor (without recourse, and without any representation or warranty) such of the Security Agreement Collateral as may be in the possession of the Administrative Agent and has not theretofore been sold or otherwise applied or released pursuant to this Agreement. As used in this Agreement, “Termination Date” shall mean the date upon which all of the Commitments shall have terminated in full, no Loans or Notes under the Credit Agreement shall be outstanding (and all Loans shall have been repaid in full), and all of the Obligations (other than Obligations pursuant to the Specified Swap Agreement) shall have been paid in full and in cash.

                 (b) In the event that any part of the Security Agreement Collateral is Disposed of in connection with a Disposition permitted by Section 7.5 of the Credit Agreement or otherwise released at the direction of the Required Lenders (or all Lenders if required by Section 10.1 of the Credit Agreement), such Security Agreement Collateral will be Disposed of free and clear of the Liens created by this Agreement, the security interests granted hereunder with respect to such Security Agreement Collateral shall terminate and the Administrative Agent, at the request and expense of the respective Grantor, will execute and deliver to such Grantor a proper Instrument or Instruments (including Uniform Commercial Code termination statements) to evidence the release of such Security Agreement Collateral and will duly assign, transfer and deliver to such Grantor (without recourse, and without any representation or warranty) such of the Security Agreement Collateral as is then being (or has been) so Disposed of or released and as may be in the possession of the Administrative Agent and has not theretofore been released pursuant to this Agreement.

                 (c) The Administrative Agent shall have no liability whatsoever to any Secured Party as a result of any release of Security Agreement Collateral by it in accordance with this Section 10.10.

     10.11. Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument.

     10.12. The Administrative Agent. (a) The Administrative Agent will hold in accordance with this Agreement all items of the Security Agreement Collateral at any time received under this Agreement. It is expressly understood and agreed by the parties hereto and each Secured Party that the obligations of the Administrative Agent as holder of the Security Agreement Collateral and interests therein and with respect to the disposition thereof, and otherwise under this Agreement, are only those expressly set forth in this Agreement. The Administrative Agent shall act hereunder on the terms and conditions set forth in Article 9 of the Credit Agreement.

             (b) Notwithstanding anything else to the contrary in this Agreement, each of the Secured Parties agrees that this Agreement may be enforced only by the action of the Administrative Agent, in each case, acting upon the instructions of the Required Lenders, and that no other Secured Parties shall have any rights individually to seek to enforce or to enforce this Agreement or to realize upon any of the Security Agreement Collateral or other security granted or to be granted by any of the other Collateral Documents, it being understood and agreed that such rights and remedies may be exercised by the Administrative Agent for the benefit of the Secured Parties upon the terms of this Agreement and the other Collateral Documents. It is understood that the agreement of the Secured Parties contained in this paragraph (b) is among, and solely for the benefit of, the Secured Parties and that, if the Required Lenders so agree (without requiring the consent of any Grantor), this Agreement may be directly enforced by any Secured Party.

     10.13. Marshalling. The Administrative Agent shall not be required to marshal any present or future collateral security (including, but not limited to, this Agreement and the Security Agreement Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of the rights of the Administrative Agent hereunder or in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights, however existing or arising. To the extent that it lawfully may, each Grantor hereby agrees that it will not invoke any Applicable Law relating to the marshalling of collateral which might cause delay in or impede the enforcement of the Administrative Agent’s rights under this Agreement or under any other Instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

     10.14. Effectiveness. This Agreement shall become effective on and as of the date hereof when the Administrative Agent, the Parent Company, and the Borrower shall have signed a counterpart hereof (whether the same or different counterparts) and shall have delivered (including by way of facsimile transmission) the same to the Administrative Agent.

     10.15. Delivery by Facsimile. Delivery of the signature pages to this Agreement by facsimile shall be as effective as delivery of manually executed counterparts of this Agreement.
