WHEREAS, each Subsidiary Guarantor is a Domestic Subsidiary of the Borrower;

WHEREAS, the proceeds of the Extensions of Credit will be used in part to enable the Borrower to make valuable transfers to the Subsidiary Guarantors in connection with the operation of their respective businesses;

WHEREAS, each Guarantor acknowledges that it will derive substantial direct and indirect benefit from the making of the Extensions of Credit; and

NOW, THEREFORE, in consideration of the premises and to induce the Administrative Agent, the Collateral Agent, the Lenders and the Letter of Credit Issuer to enter into the Credit Agreement and to induce the Lenders and the Letter of Credit Issuer to make their respective Extensions of Credit to the Borrower under the Credit Agreement and to induce one or more Lenders or Affiliates of Lenders to enter into Bank Product Agreements (including Hedge Agreements) with the Borrower, the Guarantors hereby agree with the Collateral Agent, for the benefit of the Secured Parties, as follows:

1. Defined Terms.

(a) Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement.

(b) As used herein, the term “Guaranteed Obligations” shall mean all of the Obligations now or hereafter existing under any Credit Document, whether for principal, interest (including all interest that accrues after the commencement of any proceeding of the type described in Section 11.5 of the Credit Agreement (an “Insolvency Proceeding”) irrespective of whether a claim therefor is allowed in such case or proceeding), fees, expenses or otherwise, and any and all expenses (including reasonable counsel fees and expenses) incurred by any Secured Party in enforcing any rights under this Guarantee. Without limiting the generality of the foregoing, Guaranteed Obligations shall include all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrower to the Agent, the Lenders or the Issuing Lender under any Loan Document but for the fact that they are unenforceable or not allowable, including due to the existence of a bankruptcy, reorganization or similar proceeding involving Borrower or any other guarantor. Any reference in this Agreement or in the Credit Documents to the Guaranteed Obligations shall include all or any portion thereof and any extensions, modifications, renewals, or alterations thereof, both prior and subsequent to any Insolvency Proceeding.

(d) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Guarantee shall refer to this Guarantee as a whole and not to any particular provision of this Guarantee, and Section references are to Sections of this Guarantee unless otherwise specified. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation”. The word “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.”

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

2. Guarantee.

(a) Each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantees, as primary obligor and not merely as surety, to the Collateral Agent, for the benefit of the Secured Parties, (i) the prompt and complete payment and performance when due (whether at the stated maturity, pursuant to a mandatory prepayment requirement, by acceleration or otherwise) of the Guaranteed Obligations, and (ii) the punctual and faithful performance, keeping, observance, and fulfillment by the Borrower of all agreements, conditions, covenants, and obligations of Borrower contained in the Credit Agreement and under each of the Credit Documents. Each Guarantor, jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Guarantors, with respect to the payment and performance of all of the Guaranteed Obligations, it being the intention of the parties hereto that all the Guaranteed Obligations shall be the joint and several obligations of each Guarantor without preferences or distinction among them.

(b) Each Guarantor further jointly and severally agrees to pay any and all expenses (including all reasonable fees and disbursements of counsel) that may be paid or incurred by the Collateral 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 Guaranteed Obligations and/or enforcing or preserving any rights with respect to, or collecting any or all of the Guaranteed Obligations and/or enforcing any rights with respect to, or collecting against the Guarantors under this Guarantee.

-2-

(c) Each Guarantor agrees that the Guaranteed 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 Collateral Agent or any other Secured Party hereunder.

(d) 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 Collateral 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 Guaranteed 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, remain liable for the Guaranteed 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.

(e) In the event that the Borrower fails to make any payment of any Guaranteed Obligations, on or prior to the due date thereof, or if the Borrower shall fail to perform, keep, observe, or fulfill any other obligation referred to in clause (ii) of Section 2(a) of this Guarantee in the manner provided in the Credit Agreement or any other Credit Document, each Guarantor immediately shall cause, as applicable, such payment in respect of the Guaranteed Obligations to be made or such obligation to be performed, kept, observed, or fulfilled. Each Guarantor agrees that whenever, at any time, or from time to time, it shall make any payment to the Collateral Agent or any other Secured Party on account of its liability hereunder, it will notify the Collateral 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 Collateral Agent and the other Secured Parties, and each Guarantor shall remain liable to the Collateral 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.

-3-

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 Collateral Agent or any other Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of the Collateral 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 Collateral Agent or any other Secured Party for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution, exoneration, indemnity, subrogation or reimbursement, or any other similar claim, from the Borrower, any other Guarantor, or any other guarantor of the Obligations in respect of payments made by such Guarantor hereunder, until all amounts owing to the Collateral 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 Guaranteed Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Collateral Agent and the other Secured Parties, segregated from other funds of and 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 Guaranteed Obligations, whether due or to become due, in such order as the Collateral Agent may determine. Notwithstanding anything to the contrary contained in this Guarantee, no Guarantor shall exercise any rights of contribution, exoneration, indemnity, subrogation or reimbursement, or any other similar claim, and shall not proceed or seek recourse against or with respect to any property or asset of the Borrower, any other Guarantor, or any other guarantor of the Obligations (including after payment in full of the Guaranteed Obligations) if all or any portion of the Obligations has been satisfied in connection with an exercise of remedies in respect of the Equity Interests of the Borrower, such Guarantor, or such other guarantor whether pursuant to the Security Agreement, the Pledge Agreement, or otherwise.

6. Amendments, etc. with Respect to the Guaranteed 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 Guaranteed Obligations made by the Collateral Agent or any other Secured Party may be rescinded by such party and any of the Guaranteed Obligations continued, (b) the Guaranteed 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, increased, amended, modified, accelerated, compromised, waived, surrendered or released by the Collateral 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 Bank Product Agreements (including Hedge Agreements) and any other documents executed and delivered in connection therewith and any documents entered into with the Bank Product Providers 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 Collateral Agent (or the Required Lenders, as the case may be, or, in the case of any Bank Product Agreement (including any Hedge Agreement) or documents entered into with any Bank Product Provider 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 Collateral Agent or any other Secured Party for the payment of the Guaranteed Obligations may be sold, exchanged, waived, surrendered or released. Neither the Collateral 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 Guaranteed Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any Guarantor, the Collateral 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 other guarantor of the

-4-

Obligations, and any failure by the Collateral Agent or any other Secured Party to make any such demand or to collect any payments from the Borrower or any Guarantor or other guarantor or any release of the Borrower or any Guarantor or other 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 joint and 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 Collateral 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. To the fullest extent permitted by applicable law, each Guarantor waives:

(a) any and all (i) notice of the creation, existence, contraction, incurrence, renewal, extension, amendment, waiver or accrual of any of the Guaranteed Obligations, (ii) notice of any loans or other financial accommodations made or extended under the Credit Agreement, (iii) notice of the amount of the Guaranteed Obligations, subject, however, to such Guarantor’s right to make inquiry of Collateral Agent to ascertain the amount of the Guaranteed Obligations at any reasonable time, (iv) notice of any adverse change in the financial condition of the Borrower or of any other fact that might increase such Guarantor’s risk hereunder, (v) notice of presentment for payment, demand, protest, and notice thereof as to any instrument among the Credit Documents, (vi) notice of any Default or Event of Default under any of the Credit Documents, (vii) all other notices (except if such notice is specifically required to be given to such Guarantor under this Guarantee or any other Credit Documents to which such Guarantor is a party) and demands to which such Guarantor might otherwise be entitled, (viii) notice of or proof of reliance by the Collateral Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee, the Guaranteed 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 (ix) all dealings between the Borrower and any of the Guarantors, on the one hand, and the Collateral 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.

(b) the right by statute or otherwise to require the Secured Parties to institute suit against the Borrower or any other guarantor or to exhaust any rights and remedies which any Secured Party has or may have against Borrower or any other guarantor. In this regard, such Guarantor agrees that it is bound to the payment of each and all Guaranteed Obligations, whether now existing or hereafter arising, as fully as if the Guaranteed Obligations were directly owing to the Secured Parties by such Guarantor. Guarantor further waives any defense arising by reason of any disability or other defense (other than the defense that the Guaranteed Obligations shall have been fully and finally performed and indefeasibly paid in full in cash, to the extent of any such payment) of Borrower or by reason of the cessation from any cause whatsoever of the liability of Borrower in respect thereof.

(c) (i) any right to assert to against any Secured Party any defense (legal or equitable), set-off, counterclaim, or claim which such Guarantor may now or at any time hereafter have against Borrower or any other party liable to any Secured Party, (ii)any defense, set-off, counterclaim, or claim, of any kind or nature, arising directly or indirectly from the present or future lack of perfection, sufficiency, validity, or enforceability of the Guaranteed Obligations or any security therefor, (iii) any right or defense arising by reason of any claim or defense based upon an election of remedies by any Secured Party including any defense based upon an impairment or elimination of such Guarantor’s rights of subrogation, reimbursement, contribution, or indemnity of such Guarantor against Borrower or other guarantors or sureties, (iv) the benefit of any statute of limitations affecting Guarantor’s liability hereunder or the enforcement thereof, and any act which shall defer or delay the operation of any statute of limitations applicable to the Guaranteed Obligations shall similarly operate to defer or delay the operation of such statute of limitations applicable to such Guarantor’s liability hereunder.

-5-

(d) 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 Guaranteed 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 Bank Product Agreement (including any Hedge Agreement), any of the Guaranteed 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 Collateral 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 Collateral 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 Guaranteed Obligations, or of such Guarantor under this Guarantee, in bankruptcy or in any other instance. This Guarantee includes Guaranteed Obligations arising under successive transactions continuing, compromising, extending, increasing, modifying, releasing, or renewing the Guaranteed Obligations, changing the interest rate, payment terms, or other terms and conditions thereof, or creating new or additional Guaranteed Obligations after prior Guaranteed Obligations have been satisfied in whole or in part. When pursuing its rights and remedies hereunder against any Guarantor, the Collateral 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 Guaranteed Obligations or any right of offset with respect thereto, and any failure by the Collateral 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 Collateral 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 Collateral 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 Bank Product Agreement (including any Hedge Agreement) the Credit Parties may be free from any Guaranteed 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 Collateral 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 Collateral Agent.

8. Guaranteed Obligations Secured by a Mortgage or Deed of Trust.

(a) If any of the Guaranteed Obligations or the obligations of any Guarantor under this Guarantee at any time are secured by a mortgage or deed of trust upon real property, the Collateral Agent or any Secured Party may elect, in its sole discretion, upon a default with respect to the Guaranteed Obligations or the obligations of such Guarantor under this Guarantee, to foreclose such mortgage or deed

-6-

of trust judicially or nonjudicially in any manner permitted by law, before or after enforcing this Guarantee, without diminishing or affecting the liability of such Guarantor hereunder. Guarantor understands that (i) by virtue of the operation of antideficiency law applicable to nonjudicial foreclosures, an election by the Collateral Agent or such Secured Party to nonjudicially foreclose on such a mortgage or deed of trust probably would have the effect of impairing or destroying rights of subrogation, reimbursement, contribution, or indemnity of such Guarantor against the Borrower or other guarantors or sureties, and (ii) absent the waiver given by such Guarantor herein, such an election would estop the Collateral Agent or such Secured Party from enforcing this Guarantee against Guarantor. Understanding the foregoing, and understanding that each Guarantor is hereby relinquishing a defense to the enforceability of this Guarantee, each Guarantor hereby waives any right to assert the Collateral Agent or any Secured Party any defense to the enforcement of this Guarantee, whether denominated “estoppel” or otherwise, based on or arising from an election by the Collateral Agent or such Secured Party to nonjudicially foreclose on any such mortgage or deed of trust or as a result of any other exercise of remedies, whether under a mortgage or deed of trust or under any personal property security agreement. Each Guarantor understands that the effect of the foregoing waiver may be that such Guarantor may have liability hereunder for amounts with respect to which Guarantor may be left without rights of subrogation, reimbursement, contribution, or indemnity against the Borrower or other guarantors or sureties.

(b) Without limiting the generality of any other waiver or other provision set forth in this Guarantee, each Guarantor waives all rights and defenses that Guarantor may have if all or part of the Guaranteed Obligations are secured by real property. This means, among other things:

This is an unconditional and irrevocable waiver of any rights and defenses Guarantor may have if all or part of the Guaranteed Obligations are secured by real property.

9. 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 Guaranteed Obligations is rescinded or must otherwise be restored or returned by the Collateral 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.

-7-

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

11. 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 Collateral 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 Collateral 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.

12. Authority of Agent. Each Guarantor acknowledges that the rights and responsibilities of the Collateral Agent under this Guarantee with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral 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 Collateral 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 Collateral Agent and such Guarantor, the Collateral 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.

13. 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.

14. Counterparts. This Guarantee may be executed by one or more of the arties 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 Collateral Agent and the Borrower.

15. 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.

16. Integration. This Guarantee represents the agreement of each Guarantor and the Collateral Agent with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Collateral 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.

-8-

17. 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 Collateral Agent in accordance with Section 13.1 of the Credit Agreement.

(b) Neither the Collateral Agent nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 17(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 Collateral 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 Collateral 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 Collateral 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.

18. 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.

19. Successors and Assigns. This Guarantee shall be binding upon the successors and assigns of each Guarantor and shall inure to the benefit of the Collateral 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 Collateral Agent and any such prohibited assignment shall be absolutely void.

20. 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.

21. WAIVER OF JURY TRIAL. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, EACH GUARANTOR AND THE COLLATERAL AGENT HEREBY WAIVE THERE RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS GUARANTEE OR ANY OF THE OTHER CREDIT DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH GUARANTOR AND THE COLLATERAL AGENT REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS GUARANTEE MAYBE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

-9-

22. 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 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 13 or at such other address of which the Collateral Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right of the Collateral 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 Collateral Agent or any other Secured Party to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 22 any special, exemplary, punitive or consequential damages.

23. GOVERNING LAW. THE VALIDITY OF THIS GUARANTEE AND THE OTHER CREDIT DOCUMENTS (UNLESS EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER CREDIT DOCUMENT IN RESPECT OF SUCH OTHER CREDIT DOCUMENT), THE CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF AND THEREOF, AND THE RIGHTS OF THE PARTIES HERETO AND THERETO WITH RESPECT TO ALL MATTERS ARISING HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
