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

2.1 Guarantee. (a) Each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantees to the Administrative Agent, for the ratable benefit of the Secured Parties and their respective successors, indorsees, transferees and assigns, the prompt and complete payment and performance by the Loan Parties when due (whether at the stated maturity, by acceleration or otherwise) of the Primary Obligations (other than, with respect to any Guarantor, any Excluded Swap Obligations of such Guarantor).

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

Guarantor hereunder which shall, notwithstanding any such payment (other than (x) any payment made by such Guarantor in respect of the Primary Obligations or any payment received or collected from such Guarantor in respect of the Primary Obligations), remain liable for the Primary Obligations up to the maximum liability of such Guarantor hereunder until the Primary Obligations are paid in full in cash (other than obligations and liabilities under Secured Hedge Agreements and Secured Cash Management Agreements as to which arrangements reasonably satisfactory to the applicable Hedge Bank or Cash Management Bank have been made and (y) contingent indemnification obligations that have not yet been asserted), no Letter of Credit shall be outstanding (other than those that have been Cash Collateralized) and the Commitments are terminated.

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 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.

2.3 No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by the Administrative Agent or any other Secured Parties, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any other Secured Parties against the Borrower, any other Loan Party with Primary Obligations, or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any other Secured Parties for the payment of the Primary Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower, any other Loan Party with Primary Obligations, 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 Loan Parties on account of the Primary Obligations are paid in full in cash (other than (x) obligations and liabilities under Secured Hedge Agreements and Secured Cash Management Agreements as to which arrangements reasonably satisfactory to the applicable Hedge Bank or Cash Management Bank have been made and contingent indemnification obligations that have not yet been asserted), no Letter of Credit shall be outstanding (other than those that 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 Primary Obligations shall not have been paid in full in cash, such amount shall be held by such Guarantor in trust for, or on behalf of, 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 Primary Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine.

2.4 Amendments, etc. with respect to the Primary 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 Primary Obligations made by the Administrative Agent or any other Secured Parties may be rescinded by the Administrative Agent or such other Secured Party and any of the Primary Obligations continued, and the Primary 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 the Administrative Agent or any other Secured Party, and the Credit Agreement, the other Loan Documents, the Secured Hedging Agreements and the Secured Cash Management Agreements and

any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem advisable from time to time, and 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 Primary 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 Primary 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 Primary Obligations and notice of or proof of reliance by the Administrative Agent or any other Secured Party upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Primary 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 Loan Parties, 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 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 Borrower, any other Loan Party with Primary Obligations, or any of the Guarantors with respect to the Primary 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 Secured Hedging Agreement, any Secured Cash Management Agreement, any of the Primary 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) which may at any time be available to or be asserted by the Borrower or any other Person 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) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Loan Parties for the Primary Obligations, or of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies 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 or otherwise pursue such rights and remedies as it may have against the Borrower, any other Loan Party with Primary Obligations, any other Guarantor or any other Person or against any collateral security or guarantee for the Primary Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any other Secured Party to make any such demand, to pursue such other rights or remedies or to collect any payments from the Borrower, 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 Borrower, any other Loan Party with Primary Obligations, 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 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.

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 Primary 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 (or any

other similar proceeding under other applicable law) of the Borrower, any other Loan Party with Primary Obligations, 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, any other Loan Party with Primary Obligations, 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 Administrative Agent without set-off or counterclaim in Dollars at the Funding Office.

2.8 Keepwell. Each Qualified Keepwell Provider hereby jointly and severally absolutely, unconditionally, and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this guarantee in respect of any Swap Obligation (provided, however, that each Qualified Keepwell Provider shall only be liable under this Section 2.8 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 2.8, or otherwise under this guarantee, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified Keepwell Provider under this Section 2.8 shall remain in full force and effect until such time as the Loans, the L/C Obligations and the other Obligations shall have been paid in full in cash (other than (x) obligations and liabilities under Secured Hedge Agreements and Secured Cash Management Agreements as to which arrangements reasonably satisfactory to the applicable Hedge Bank or Cash Management Bank have been made and (y) contingent indemnification obligations that have not yet been asserted), the Commitments have been terminated and no Letters of Credit (other than those that have been Cash Collateralized) shall be outstanding. Each Qualified Keepwell Provider intends that this Section 2.8 constitute, and this Section 2.8 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

3.1 Application of Proceeds. At such intervals as may be agreed upon by the Borrower and the Administrative Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the Administrative Agent’s election, the Administrative Agent may apply any proceeds of the guarantee set forth in Section 2, in payment of the Obligations in the order set forth in Section 8.04 of the Credit Agreement.

3.2 Subordination. Each Loan Party hereby agrees that, upon the occurrence and during the continuance of an Event of Default, unless otherwise agreed in writing by the Administrative Agent, all Indebtedness owing by it to any Subsidiary of the Borrower shall be fully subordinated to the indefeasible payment in full in cash of such Loan Party’s Obligations.

4.1 Administrative Agent’s Appointment as Attorney-in-Fact, etc. Each Loan Party hereby irrevocably constitutes and appoints the Administrative 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 Loan Party and in the name of such Loan Party 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.

4.2 Authority of Administrative Agent. Each Loan Party acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative 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 Administrative Agent and the 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 the Loan Party, 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 Loan Party shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

5.1 Amendments. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 10.01 of the Credit Agreement.

5.2 Notices. All notices, requests and demands to or upon the Administrative Agent or any Loan Party hereunder shall be effected in the manner provided for in Section 10.02 of the Credit Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1.

5.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Administrative Agent nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 5.1), 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 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 which the Administrative Agent or such other Secured Party 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.

5.4 Enforcement Expenses; Indemnification. (a) Each Guarantor agrees to pay or reimburse each Secured Party 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 the Secured Parties in accordance with (and to the extent provided in) Section 10.04 of the Credit Agreement.

(b) Each Guarantor agrees to pay, and to save and hold the Administrative Agent and the other Secured Parties 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 in connection with any of the transactions contemplated by this Agreement.

(c) Each Guarantor agrees to pay, and to save the Administrative Agent and the other Secured Parties 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 Borrower would be required to do so pursuant to Section 10.04 and Section 10.05 of the Credit Agreement.

(d) The agreements in this Section 5.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Loan Documents.

5.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Loan Party and shall inure to the benefit of the Administrative Agent and the other Secured Parties and their successors and assigns; provided that no Loan Party may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent.

5.6 Set-Off. In addition to any rights and remedies of the Secured Parties provided by law, each Secured Party shall have the right, without notice to any Loan Party, any such notice being expressly waived by each Loan Party to the extent permitted by applicable law, upon any Obligations becoming due and payable by any Loan Party (whether at the stated maturity, by acceleration or otherwise), to apply to the payment of such Obligations, by setoff or otherwise, 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, any affiliate thereof or any of their respective branches or agencies to or for the credit or the account of such Loan Party. Each Secured Party agrees promptly to notify the relevant Loan Party and the Administrative Agent after any such application made by such Secured Party, provided that the failure to give such notice shall not affect the validity of such application; provided further, that to the extent prohibited by applicable law as described in the definition of “Excluded Swap Obligation” under the Credit Agreement, no amounts received from, or set off with respect to, any Guarantor shall be applied to any Excluded Swap Obligations of such Guarantor.

5.7 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by email or telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement shall become effective when it shall have been executed by the Administrative Agent and the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement. The Administrative Agent may also require that any such documents and signatures delivered by telecopier or other electronic transmission be confirmed by a manually-signed original thereof within a reasonable timeframe thereafter; provided that the failure to request or deliver the same shall not limit the effectiveness of any document or signature delivered by electronic transmission.

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

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

5.10 Integration. This Agreement, the other Loan Documents and the Secured Hedging Agreements and Secured Cash Management Agreements represent the agreement of the Loan Parties, the Administrative Agent and the Secured Parties with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any other Secured Party relative to subject matter hereof and thereof not expressly set forth or referred to herein, in the other Loan Documents, in the Secured Hedging Agreements or the Secured Cash Management Agreements.

If for any reason such agent shall cease to be available to act as such, each Loan Party agrees to irrevocably appoint another such agent in New York City, as its authorized agent for service of process, on the terms and for the purposes specified in this paragraph (d). Nothing in this

Agreement or any other document executed in connection herewith will affect the right of any party hereto to serve process in any other manner permitted by applicable Law or to obtain jurisdiction over any party or bring actions, suits or proceedings against any party in such other jurisdictions, and in such matter, as may be permitted by applicable Law; 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 any special, exemplary, punitive or consequential damages.
