SECTION 2 GUARANTEE

2.1 Guarantee.

(b) Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder and under the other Loan Documents shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal and state laws relating to the insolvency of debtors (after giving effect to the right of contribution provided in Section 2.2).

(c) Each Guarantor agrees that the Borrower Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of the Collateral Agent or any Lender hereunder.

(d) The guarantee contained in this Section 2 shall remain in full force and effect until all the Borrower Obligations and the obligations of each Guarantor under the guarantee contained in this Section 2 shall have been satisfied by payment in full, no Letter of Credit shall be outstanding (or any outstanding Letters of Credit have been cash collateralized) and the Commitments shall be terminated, notwithstanding that from time to time during the term of the Credit Agreement the Company may be free from any Borrower Obligations.

(e) No payment made by the Company, any of the Guarantors, any other guarantor or any other Person or received or collected by the Collateral Agent or any Lender from the Company, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Borrower Obligations or any payment

received or collected from such Guarantor in respect of the Borrower Obligations), remain liable for the Borrower Obligations up to the maximum liability of such Guarantor hereunder until the Borrower Obligations are paid in full, no Letter of Credit is outstanding (or any outstanding Letters of Credit have been cash collateralized) and the Commitments are terminated.

(f) The guarantee contained in this Agreement is a guarantee of payment and not of collection.

2.2 Right of Contribution. Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of Section 2.3. The provisions of this Section 2.2 shall in no respect limit the obligations and liabilities of any Guarantor to the Agents and the Lenders, and each Guarantor shall remain liable to the Agents and the Lenders for the full amount guaranteed by such Guarantor hereunder.

2.3 No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by any Agent or any Lender, no Guarantor shall be entitled to be subrogated to any of the rights of any Agent or any Lender against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by any Agent or any Lender for the payment of the Borrower Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Agents and the Lenders by the Company on account of the Borrower Obligations are paid in full, no Letter of Credit is outstanding (or any outstanding Letters of Credit have been cash collateralized) and the Commitments are terminated. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Borrower Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Agents and the Lenders segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Collateral Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Collateral Agent, if required), to be applied against the Borrower Obligations, whether matured or unmatured, in such order as the Collateral Agent may determine.

2.4 Amendments, etc. with Respect to the Borrower Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Borrower Obligations made by any Agent or any Lender may be rescinded by such Agent or such Lender, as the case may be, and any of the Borrower Obligations continued, and the Borrower Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Agent or any Lender, and the Credit Agreement, the other Loan Documents, any Eligible Hedge Agreement and any other documents executed and delivered in connection therewith may be amended, modified,

supplemented or terminated, in whole or in part, as the Collateral Agent (or the relevant Lenders) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by any Agent or any Lender for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released. No Agent or Lender shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in this Section 2 or any property subject thereto.

2.5 Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Borrower Obligations and notice of or proof of reliance by any Agent or any Lender upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Borrower Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between the Company and any of the Guarantors, on the one hand, and the Agents and the Lenders, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Company or any of the Guarantors with respect to the Borrower Obligations. Each Guarantor understands and agrees that the guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity or enforceability of the Credit Agreement, any other Loan Document, any Eligible Hedge Agreement, any of the Borrower Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by any Agent or any Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Company or any other Person against any Agent or any Lender, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Company or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Company for the Borrower Obligations, or of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance other than the express written release of such Guarantor from this Agreement by the Collateral Agent. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the Collateral Agent or any Lender may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against the Company, any other Guarantor or any other Person or against any collateral security or guarantee for the Borrower Obligations or any right of offset with respect thereto, and any failure by the Collateral Agent or any Lender to make any such demand, to pursue such other rights or remedies or to collect any payments from the Company, any other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Company, any other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any Agent or any Lender against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

2.6 Reinstatement. The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of

any of the Borrower Obligations is rescinded or must otherwise be restored or returned by any Agent or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

2.7 Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Collateral Agent without set-off or counterclaim in Dollars at the office of the Collateral Agent located at Morgan Stanley & Co. Incorporated, 750 Seventh Avenue, 11^th Floor, New York, New York 10020, Attn: Alice Lee (or such other address as shall be specified from time to time by the Collateral Agent).

All rights of the Collateral Agent and the security interests granted to the Collateral Agent hereunder, and all obligations of each Grantor hereunder, shall be absolute and unconditional, irrespective of, among other things, any lack of validity or enforceability of any other Loan Document.

(c) At the Collateral Agent’s reasonable request, each Grantor shall deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Receivables that are part of the Collateral, including, without limitation, all original orders, invoices and shipping receipts.

6.2 Communications with Account Debtors and Obligors; Grantors Remain Liable. (a) The Collateral Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default communicate with Account Debtors and obligors under the Collateral to verify with them to the Collateral Agent’s satisfaction the existence, amount and terms of any such Collateral.

(b) Upon the request of the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify Account

Debtors and obligors on the Collateral that such Collateral has been assigned to the Collateral Agent for the ratable benefit of the Agents and the Lenders and that payments in respect thereof shall be made directly to the Collateral Agent.

(c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under the Collateral to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. No Agent or Lender shall have any obligation or liability under any Collateral (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by any Agent or any Lender of any payment relating thereto, nor shall any Agent or any Lender be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Collateral (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

6.3 Pledged Stock. (a) Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent’s intent to exercise its corresponding rights pursuant to Section 6.3(b), each Grantor shall be permitted to receive all cash dividends paid in respect of the Pledged Stock and all payments made in respect of the Pledged Debt, in each case paid in the normal course of business of the relevant Issuer and consistent with past practice, to the extent permitted in the Credit Agreement, and to exercise all voting and corporate rights with respect to the Pledged Securities, provided, however, that no vote shall be cast or corporate right exercised or other action taken which, in the Collateral Agent’s reasonable judgment, would impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Credit Agreement, this Agreement or any other Loan Document.

(b) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such rights to the relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Securities and make application thereof to the Obligations in such order as the Collateral Agent may determine, and (ii) any or all of the Pledged Securities shall be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or its nominee may thereafter exercise (x) all voting, corporate and other rights pertaining to such Pledged Securities at any meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Securities as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Securities upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate structure of any Issuer, or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Pledged Securities, and in connection therewith, the right to deposit and deliver any and all of the Pledged Securities with any committee, depositary, transfer

agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged Securities pledged by such Grantor hereunder to (i) comply with any instruction received by it from the Collateral Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) upon the occurrence of an Event of Default, pay any dividends or other payments with respect to the Pledged Securities directly to the Collateral Agent.

6.4 Proceeds to be Turned Over To Collateral Agent. In addition to the rights of the Collateral Agent and the Lenders specified in Section 6.1 with respect to payments of Receivables, if an Event of Default shall occur and be continuing, all Proceeds received by any Grantor consisting of cash, checks, Cash Equivalents and other near-cash items shall be held by such Grantor in trust for the Agents and the Lenders, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly indorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its sole dominion and control. All Proceeds while held by the Collateral Agent in a Collateral Account (or by such Grantor in trust for the Agents and the Lenders) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 6.5.

6.5 Application of Proceeds. (a) At such intervals as may be agreed upon by the Company and the Collateral Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the Collateral Agent’s election, the Collateral Agent may apply all or any part of Proceeds held in any Collateral Account in payment of the Obligations (after payment of any amounts payable to the Collateral Agent pursuant to Section 8.4 of this Agreement), in the following manner:

(i) first, paid to the Agents for any amounts then owing to the Agents pursuant to Section 11.5 of the Credit Agreement or otherwise under the Loan Documents, ratably in accordance with such respective amounts then owing to the Agents; and

(ii) second, ratably (A) paid to the Lenders for any amounts then owing to them under the Loan Documents ratably in accordance with such respective amounts then owing to such Lenders and (B) used to cash collateralize outstanding Letters of Credit.

(b) Any balance of such Proceeds remaining after the Obligations shall have been paid in full, no Letters of Credit shall be outstanding (or all outstanding Letters of

Credit shall have been cash collateralized) and the Commitments shall have terminated, shall be paid over to the Company or to whomsoever may be lawfully entitled to receive the same.

6.6 Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Agents and the Lenders, may exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate, realize upon the Collateral or take possession of any Collateral not yet in its possession without demand or legal process, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Agent or any Lender or elsewhere upon such terms and conditions and at such prices as are commercially reasonable, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent and each Lender shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released, and may pay for the Collateral by crediting the Obligations. Each Grantor further agrees that upon and during the continuance of an Event of Default, at the Collateral Agent’s request, it shall assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent and each Lender shall have the right to occupy any premises owned or leased (subject to any required landlord consent) by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate their rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 6.6, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Agents and the Lenders hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615(a)(3) of the UCC, need the Collateral Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against any Agent or any Lender arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition.

6.7 Intellectual Property. If any Event of Default shall occur and be continuing, in the event of any sale or other disposition of any of the Intellectual Property of any Grantor in accordance with this Section 6, the goodwill symbolized by any Trademarks subject to such sale or other disposition shall be included therein, and such Grantor shall supply to the Collateral Agent or its designee such Grantor’s know-how and expertise, and documents and things relating to any Intellectual Property subject to such sale or other disposition, and such Grantor’s customer lists and other records and documents relating to such Intellectual Property and to the manufacture, distribution, advertising and sale of products and services of such Grantor.

6.8 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Obligations and the reasonable fees and disbursements of any attorneys employed by any Agent or any Lender to collect such deficiency.

SECTION 7 THE COLLATERAL AGENT

7.1 Collateral Agent’s Appointment as Attorney-in-Fact, etc. (a) Each Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following:

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Receivable that is part of the Collateral or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any such Receivable or with respect to any other Collateral whenever payable;

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Collateral Agent may request to evidence the Agents’ and the Lenders’ security interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

(iv) execute, in connection with any sale provided for in Section 6.6, any indorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(v) (1) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (2) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (3) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (4) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (5) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (6) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Agent may deem appropriate; (7) assign any Intellectual Property included in the Collateral (along with the goodwill of the business to which any such Intellectual Property pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its sole discretion determine; and (8) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent’s and the Lenders’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 7.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 7.1(a) unless an Event of Default shall have occurred and be continuing.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The reasonable expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 7.1, together with interest thereon at a rate per annum equal to the rate per annum at which interest would then be payable on past due Base Rate Loans under the Credit Agreement, from the date of payment by the Collateral Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand.

(d) All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

7.2 Duty of Collateral Agent. The Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. No Agent or Lender nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Agents and the Lenders hereunder are solely to protect the Agents’ and the Lenders’ interests in the Collateral and shall not impose any duty upon any Agent or any Lender to exercise any such powers. The Agents and the Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

7.3 Authorization of Financing Statements. Pursuant to Sections 9-502 and 9-509 of the UCC and any other applicable law, each Grantor hereby authorizes the Collateral Agent to file or record financing statements or continuation statements, and amendments thereto, and other filing or recording documents or instruments with respect to the Collateral or other statutory liens held by the Collateral Agent in such form and in such offices as the Collateral Agent reasonably determines appropriate to perfect the security interests of the Collateral Agent under this Agreement. Such financing statements may describe the Collateral in the same manner as described in this Agreement or may contain an indication or description of the Collateral that describes such property in any other manner as the Collateral Agent may determine is necessary or advisable to ensure the perfection of the security interest in Collateral granted to the Collateral Agent in connection herewith, including, without limitation, describing such property as “all assets” or “all personal property.” A photographic or other reproduction or summation of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any jurisdiction. Each Grantor ratifies its authorization for the Collateral Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

7.4 Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Agreement with respect to any action

taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Agents and the Lenders, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the Agents and the Lenders with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

SECTION 8 MISCELLANEOUS

8.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with subsection 11.1 of the Credit Agreement.

8.2 Notices. All notices, requests and demands to or upon the Collateral Agent or any Grantor hereunder shall be effected in the manner provided for in subsection 11.2 of the Credit Agreement, provided that any such notice, request or demand to or upon any Grantor shall be addressed to such Grantor at its notice address set forth on Schedule 1.

8.3 No Waiver by Course of Conduct; Cumulative Remedies. The Agents and the Lenders shall not by any act (except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of any Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by any Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which such Agent or such Lender, as the case may be, would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor agrees to pay or reimburse each Agent and Lender for all its costs and expenses incurred in collecting against such Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Guarantor is a party, including, without limitation, the fees and disbursements of counsel to each Lender and of counsel to the Collateral Agent.

(b) Each Guarantor agrees to pay, and to save the Agents and the Lenders harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral.

(c) Each Guarantor agrees to pay, and to save the Agents and the Lenders harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the extent the Company would be required to do so pursuant to subsection 11.5 of the Credit Agreement.

(d) The agreements in this Section 8.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Loan Documents.

8.5 Successors and Assigns; Continuing Security Interest. This Agreement shall be binding upon each Grantor and its respective successors and assigns and shall inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Agents and the Lenders and their successors and assigns, provided that no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Collateral Agent. This Agreement shall create a continuing security interest in the Collateral and shall remain in full force and effect until the latest of (i) the payment in full in cash of the Obligations, (ii) the termination of the Commitments and (iii) the expiration, termination or cash collateralization of all Letters of Credit and all Eligible Hedge Agreements. Without limiting the generality of the foregoing clause, any Lender may assign or otherwise transfer all or any portion of its rights and obligations under the Credit Agreement (including, without limitation, all or any portion of its Commitments, the Loan owing to it and the Note or Notes, if any, held by it) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Lender herein or otherwise, in each case as provided in Section 11.6 of the Credit Agreement.

8.6 Set-Off. Each Grantor hereby irrevocably authorizes each Agent and each Lender at any time and from time to time while an Event of Default pursuant to Section 9(a) of the Credit Agreement shall have occurred and be continuing, without notice to such Grantor or any other Grantor, any such notice being expressly waived by each Grantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Agent or such Lender to or for the credit or the account of such Grantor, or any part thereof in such amounts as such Agent or such Lender may elect, against and on account of the obligations and liabilities of such Grantor to such Agent or such Lender hereunder and claims of every nature and description of the Agents or the Lenders against such Grantor, in any currency, whether arising hereunder, under the Credit Agreement, any other Loan Document or otherwise, as such Agent or such Lender may elect, whether or not such Agent or such Lender has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. Each Agent and each Lender shall notify such Grantor promptly of any such set-off and the application made by such Agent or such Lender of the proceeds thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Agents and each Lender under this Section 8.6 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Agents or such Lender may have.

8.7 Security Interest Absolute. The obligations of each Grantor under this Agreement are independent of the Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate action or actions may be brought and prosecuted against each Grantor to enforce this Agreement, irrespective of whether any action is brought against such Grantor or any other Loan Party or whether such Grantor or any other Loan Party is joined in any such action or actions. All rights of the Collateral Agent and the other Agents and Lenders and the pledge, assignment and security interest hereunder, and all obligations of each Grantor hereunder, shall be irrevocable, absolute and unconditional irrespective of, and each Grantor hereby irrevocably waives (to the maximum extent permitted by applicable law) any defenses it may now have or may hereafter acquire in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of any Loan Document or any other agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations of any other Loan Party under or in respect of the Loan Documents or any other amendment or waiver of or any consent to any departure from any Loan Document, including, without limitation, any increase in the Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise;

(c) any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Obligations;

(d) any manner of application of any Collateral or any other collateral, or proceeds thereof, to all or any of the Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents or any other assets of any Loan Party or any of its Subsidiaries;

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f) any failure of any Agent or Lender to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, assets, nature of assets, liabilities or prospects of any other Loan Party now or hereafter known to such Agent or Lender (each Grantor waiving any duty on the part of the Agents and Lenders to disclose such information);

(g) the failure of any other Person to execute this Agreement or any other Security Document, guaranty or agreement or the release or reduction of liability of any other Grantor or other grantor or surety with respect to the Obligations; or

(h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Agent or Lender that might otherwise constitute a defense available to, or a discharge of, such Grantor or any other Grantor or a third party grantor of a security interest (other than the defense of

payment or performance in full or the release of such Grantor from its obligations hereunder in accordance with Section 8.18).

This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Obligations is rescinded or must otherwise be returned by any Agent or Lender or by any other Person upon the insolvency, bankruptcy or reorganization of any Loan Party or otherwise, all as though such payment had not been made.

8.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

8.9 Mortgages. In the event that any of the Collateral hereunder is also subject to a valid and enforceable Lien under the terms of any Mortgage and the terms of such Mortgage are inconsistent with the terms of this Agreement, then with respect to such Collateral, the terms of such Mortgage shall be controlling in the case of fixtures and real estate leases, letting and licenses of, and contracts and agreements relating to the lease of, real property, and the terms of this Agreement shall be controlling in the case of all other Collateral.

8.10 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.
