(f) The meanings given to terms defined herein shall be equally applicable to both the singular and plural forms of such terms.

2. Guarantee.

(a) Subject to the provisions of Section 2(b), each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantees, as primary obligor and not merely as surety, to the Administrative Agent, for the benefit of the Secured Parties, the prompt and complete payment and performance when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations.

(b) Anything herein or in any other Credit Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder and under the other Credit Documents shall in no event exceed the amount that can be guaranteed by such Guarantor under applicable laws relating to the insolvency of debtors.

(c) Each Guarantor further agrees to pay any and all expenses (including all reasonable fees and disbursements of counsel) that may be paid or incurred by the Administrative Agent or any other Secured Party in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, such Guarantor under this Guarantee.

(d) Each Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing this Guarantee or affecting the rights and remedies of the Administrative Agent or any other Secured Party hereunder.

(e) No payment or payments made by the Borrower, any of the Guarantors, any other guarantor or any other Person or received or collected by the Administrative Agent or any other Secured Party from the Borrower, 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 Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder, which shall, notwithstanding any such payment or payments other than payments made by such Guarantor in

respect of the Obligations or payments received or collected from such Guarantor in respect of the Obligations, remain liable for the Obligations up to the maximum liability of such Guarantor hereunder until the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letters of Credit shall be outstanding.

(f) Each Guarantor agrees that whenever, at any time, or from time to time, it shall make any payment to the Administrative Agent or any other Secured Party on account of its liability hereunder, it will notify the Administrative Agent in writing that such payment is made under this Guarantee for such purpose.

3. 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 who 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 5 hereof. The provisions of this Section 3 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent and the other Secured Parties, and each Guarantor shall remain liable to the Administrative Agent and the other Secured Parties for the full amount guaranteed by such Guarantor hereunder.

4. Right of Set-off. In addition to any rights and remedies of the Secured Parties provided by law, each Guarantor hereby irrevocably authorizes each Secured Party at any time and from time to time following the occurrence and during the continuance of an Event of Default without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each Guarantor, upon any amount becoming due and payable by such Guarantor hereunder (whether at stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount 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 Secured Party to or for the credit or the account of such Guarantor. Each Secured Party shall notify such Guarantor promptly of any such set-off and the appropriation and application made by such Secured Party, provided that the failure to give such notice shall not affect the validity of such set-off and application.

5. No Subrogation. Notwithstanding any payment or payments made by any of the Guarantors hereunder or any set-off or appropriation and application of funds of any of the Guarantors by the Administrative Agent or any other Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Party against the Borrower or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any other Secured Party for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Administrative Agent and the other Secured Parties by the Credit Parties on account of the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letters of Credit shall be outstanding. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in

trust for the Administrative Agent and the other Secured Parties, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether due or to become due, in such order as the Administrative Agent may determine.

6. Amendments, etc. with Respect to the Obligations; Waiver of Rights. 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, (a) any demand for payment of any of the Obligations made by the Administrative Agent or any other Secured Party may be rescinded by such party and any of the Obligations continued, (b) the Obligations, or the liability of any other party 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 the Administrative Agent or any other Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit and any other documents executed and delivered in connection therewith and the Hedge Agreements and any other documents executed and delivered in connection therewith and any documents entered into with the Administrative Agent or any of its affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Hedge Agreement or documents entered into with the Administrative Agent or any of its affiliates in connection with treasury, depositary or cash management services or in connection with any automated clearinghouse transfer of funds, the party thereto) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any other Secured Party for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any Guarantor, the Administrative Agent or any other Secured Party may, but shall be under no obligation to, make a similar demand on the Borrower or any Guarantor or guarantor, and any failure by the Administrative Agent or any other Secured Party to make any such demand or to collect any payments from the Borrower or any Guarantor or guarantor or any release of the Borrower or any Guarantor or guarantor shall not relieve any Guarantor in respect of which a demand or collection is not made or any Guarantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any other Secured Party against any Guarantor. For the purposes hereof, “demand” shall include the commencement and continuance of any legal proceedings.

7. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, contraction, incurrence, renewal, extension, amendment, waiver or accrual of any of the Obligations, and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee, the Obligations or any of them, shall conclusively be deemed to have been created, contracted or incurred, or

renewed, extended, amended, waived or accrued, in reliance upon this Guarantee; and all dealings between the Borrower and any of the Guarantors, on the one hand, and the Administrative Agent and the other Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Borrower or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, regularity or enforceability of the Credit Agreement, any other Credit Document, any Letter of Credit or any Hedge Agreement, any of the 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 the Administrative Agent or any other Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to or be asserted by the Borrower against the Administrative Agent or any other Secured Party or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or such Guarantor) that constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower for the Obligations, or of such Guarantor under this Guarantee, in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent and any other Secured Party may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Borrower or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any other Secured Party to pursue such other rights or remedies or to collect any payments from the Borrower or any such 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 Borrower or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent and the other Secured Parties against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the other Secured Parties, and their respective successors, indorsees, transferees and assigns, until all the Obligations under the Credit Documents shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (other than any Letters of Credit that shall have been cash collateralized or otherwise provided for in a manner satisfactory to the Letter of Credit Issuer in respect thereof), notwithstanding that from time to time during the term of the Credit Agreement and any Hedge Agreement the Credit Parties may be free from any Obligations. A Guarantor shall automatically be released from its obligations hereunder and the Guarantee of such Guarantor shall be automatically released upon the consummation of any transaction permitted by the Credit Agreement as a result of which such Guarantor ceases to be a Domestic Subsidiary of the Borrower. In connection with any such release, the Administrative Agent shall execute and deliver to any Guarantor, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to the preceding sentence of this Section 7 shall be without recourse to or warranty by the Administrative Agent.

8. Reinstatement. This Guarantee 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 Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any other Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower 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 Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

9. Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in Dollars at the Administrative Agent’s Office.

10. Representations and Warranties; Covenants.

(a) Each Guarantor hereby represents and warrants that the representations and warranties set forth in Section 8 of the Credit Agreement as they relate to such Guarantor or in the other Credit Documents to which such Guarantor is a party, each of which is hereby incorporated herein by reference, are true and correct, and the Administrative Agent and each other Secured Party shall be entitled to rely on each of them as if they were fully set forth herein.

(b) Each Guarantor hereby covenants and agrees with the Administrative Agent and each other Secured Party that, from and after the date of this Guarantee until the Obligations under the Credit Documents are paid in full, the Commitments are terminated and no Letter of Credit remains outstanding, such Guarantor shall take, or shall refrain from taking, as the case may be, all actions that are necessary to be taken or not taken so that no violation of any provision, covenant or agreement contained in Section 9 or 10 of the Credit Agreement, and so that no Default or Event of Default, is caused by any act or failure to act of such Guarantor or any of its Subsidiaries.

11. Authority of Agent. Each Guarantor acknowledges that the rights and responsibilities of the Administrative Agent under this Guarantee with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Guarantee shall, as between the Administrative Agent and the other Secured Parties, 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 Administrative Agent and such Guarantor, the Administrative Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

12. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 13.2 of the Credit Agreement. All communications and notices hereunder to each Guarantor shall be given to it in care of the Borrower at the Borrower’s address set forth in Section 13.2 of the Credit Agreement.

13. Counterparts. This Guarantee may be executed by one or more of the parties to this Guarantee on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Guarantee signed by all the parties shall be lodged with the Administrative Agent and the Borrower.

14. Severability. Any provision of this Guarantee that 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. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

15. Integration. This Guarantee represents the agreement of each Guarantor and the Administrative Agent with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any other Secured Party relative to the subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents.

16. Amendments in Writing; No Waiver; Cumulative Remedies.

(a) None of the terms or provisions of this Guarantee may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected Guarantor(s) and the Administrative Agent in accordance with Section 13.1 of the Credit Agreement.

(b) Neither the Administrative Agent nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 16(a) hereof), 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 or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any other Secured Party, 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 the Administrative Agent or any other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent or any Secured Party would otherwise have on any future occasion.

(c) The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

17. Section Headings. The Section headings used in this Guarantee are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

18. Successors and Assigns. This Guarantee shall be binding upon the successors and assigns of each Guarantor and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their respective successors and assigns except that no Guarantor may assign, transfer or delegate any of its rights or obligations under this Guarantee without the prior written consent of the Administrative Agent.

19. Additional Guarantors. Each Subsidiary of the Borrower that is required to become a party to this Guarantee pursuant to Section 9.11 of the Credit Agreement shall become a Guarantor, with the same force and effect as if originally named as a Guarantor herein, for all purposes of this Guarantee upon execution and delivery by such Subsidiary of a Supplement in the form of Annex B hereto. The execution and delivery of any instrument adding an additional Guarantor as a party to this Guarantee shall not require the consent of any other Guarantor hereunder. The rights and obligations of each Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor as a party to this Guarantee.

20. WAIVER OF JURY TRIAL. EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS GUARANTEE, ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

21. Submission to Jurisdiction; Waivers. Each Guarantor hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Guarantee and the other Credit Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Guarantor at its address referred to in Section 12 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right of the Administrative Agent or any other Secured Party to effect service of process in any other manner permitted by law or shall limit the right of the Administrative Agent or any other Secured Party to xxx in any other jurisdiction; and
