SECTION 2.1. Guaranty. Each Guarantor jointly and severally absolutely, unconditionally and irrevocably:

(a) guarantees, as a primary obligor and not merely as a surety, the full and punctual payment and performance when due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise, of all Obligations of each Obligor now or hereafter existing, whether for principal, interest (including interest accruing at the then applicable rate provided in the Credit Agreement after the occurrence of any Default set forth in Section 8.1.9 of the Credit Agreement, whether or not a claim for post-filing or post-petition interest is allowed or allowable under applicable law following the institution of a proceeding under bankruptcy, insolvency or similar laws), fees, Reimbursement Obligations, expenses or otherwise (including all such amounts

which would become due but for the operation of the automatic stay under Section 362(a) of the United States Bankruptcy Code, 11 U.S.C. §362(a), and the operation of Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C. §502(b) and §506(b) and any other Applicable Laws of similar effect binding on the Obligors, including the applicable provisions of the Ley de Concursos Mercantiles of Mexico);

(b) agrees that the Obligations may be extended or renewed, in whole or in part, or amended or modified, without notice to or further assent from it, and that it will remain bound upon its guarantee hereunder notwithstanding any extension renewal, amendment or modification of any Obligation;

(c) indemnifies and holds harmless each Secured Party for any and all reasonable and documented costs and expenses (including reasonable attorneys’ fees and expenses) incurred by such Secured Party in enforcing any rights under this Guaranty;

provided, that (i) each Guarantor shall only be liable under this Guaranty for the maximum amount of such liability that can be hereby incurred without rendering this Guaranty, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount and (ii) notwithstanding anything to the contrary contained herein, the Guarantors (individually and collectively) shall not be liable under this Guaranty with respect to Indebtedness in an aggregate principal amount that exceeds the greater of (x) $150,000,000 and (y) the Secured Debt Cap (as defined in the Existing Indentures). This Guaranty constitutes a guaranty of payment when due and not merely of collection, and each Guarantor specifically agrees that it shall not be necessary or required that any Secured Party exercise any right, assert any claim or demand or enforce any remedy whatsoever against any Obligor or any other Person before or as a condition to the obligations of such Guarantor hereunder.

SECTION 2.2. Reinstatement, etc. Each Guarantor, jointly and severally, agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part) of any of the Obligations is invalidated, declared to be fraudulent or preferential, set aside, rescinded or must otherwise be restored by any Secured Party, including upon the occurrence of any Default set forth in Section 8.1.9 of the Credit Agreement or otherwise, all as though such payment had not been made.

SECTION 2.3. Agreement to Pay; Subrogation. In furtherance of the foregoing and not in limitation of any other right that the Administrative Agent or any other Secured Party has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Borrower or any Guarantor to pay any Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Guarantor hereby promises to and will forthwith pay, or cause to be paid, to the Administrative Agent for distribution to the applicable Secured Parties in cash the amount of such unpaid Obligation. Upon payment by any Guarantor of any sums to the Administrative Agent as provided above, all rights of such Guarantor against the Borrower or any other Guarantor arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subject to Section 2.7 hereunder.

SECTION 2.4. Guaranty Absolute, etc. This Guaranty shall in all respects be a continuing, absolute, unconditional and irrevocable guaranty of payment, and shall remain in full force and effect until the Loan Repayment Date has occurred. Each Guarantor jointly and severally guarantees that the Obligations of each Obligor shall be paid strictly in accordance with the terms of each Loan Document under which they arise, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Secured Party with respect thereto. The liability of each Guarantor under this Guaranty shall be joint and several, absolute, unconditional and irrevocable irrespective of:

(a) any lack of validity, legality or enforceability of any Loan Document;

(b) the failure of any Secured Party (i) to assert any claim or demand or to enforce any right or remedy against any Obligor or any other Person (including any other guarantor) under the provisions of any Loan Document or otherwise, or (ii) to exercise any right or remedy against any other guarantor (including any Guarantor) of, or collateral securing, any Obligations;

(c) any change in the time, manner or place of payment of, or in any other term of, all or any part of the Obligations, or any other extension, compromise or renewal of any Obligation, or any amendment to, rescission, waiver, or other modification of, or any consent to or departure from, any of the terms of any Loan Document;

(d) any reduction, limitation, impairment or termination of any Obligations for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and each Guarantor hereby waives any right to or claim of) any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Obligations or otherwise;

(e) any addition, exchange or release of any collateral or of any Person that is (or will become) a guarantor (including a Guarantor hereunder) of the Obligations, or any surrender or non-perfection of any collateral, or any amendment to, or waiver or release of, or addition to, or consent to or departure from, any other guaranty held by any Secured Party securing any of the Obligations; or

(f) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, any Obligor, any surety or any guarantor.

SECTION 2.5. Setoff. Each Guarantor hereby irrevocably authorizes the Administrative Agent and each Lender, without the requirement that any notice be given to such Guarantor (such notice being expressly waived by each Guarantor), upon the occurrence and during the continuance of any Default described in Section 8.1.9 of the Credit Agreement or, with the consent of the Required Lenders, upon the occurrence and during the continuance of any other Event of Default, to set-off and appropriate and apply to the payment of the Obligations (whether or not then due, and whether or not any Secured Party has made any demand for payment of the Obligations), any and all balances, claims, credits, deposits (general or special, time or demand, provisional or final), accounts or money of such Guarantor then or thereafter maintained with

such Secured Party; provided, that any such appropriation and application shall be subject to the provisions of Section 4.8 of the Credit Agreement. Each Secured Party agrees to notify the Borrower and the Administrative Agent after any such setoff and application made by such Secured Party; provided, that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Secured Party under this Section are in addition to other rights and remedies (including other rights of setoff under applicable law or otherwise) which such Secured Party may have.

SECTION 2.6. Waiver, etc. Each Guarantor waives presentment to, demand of payment from and protest to the Borrower or any other Guarantor of any of the Obligations, and also waives promptness, diligence, notice of acceptance, notice of protest for nonpayment and any other notice with respect to any of the Obligations and this Guaranty and any requirement that any Secured Party protect, secure, perfect or insure any Lien, or any property subject thereto, or exhaust any right or take any action against any Obligor or any other Person (including any other guarantor) or any collateral securing the Obligations, as the case may be.

SECTION 2.7. Postponement of Subrogation, etc. Each Guarantor agrees that it will not exercise any rights which it may acquire by way of rights of subrogation under any Loan Document to which it is a party, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from any Obligor, in respect of any payment made under any Loan Document or otherwise, until following the Loan Repayment Date. Any amount paid to any Guarantor on account of any such subrogation rights prior to the Loan Repayment Date shall be held in trust for the benefit of the Secured Parties and shall immediately be paid and turned over to the Administrative Agent for the benefit of the Secured Parties in the exact form received by such Guarantor (duly endorsed in favor of the Administrative Agent, if required), to be credited and applied against the Obligations, whether matured or unmatured, in accordance with Section 2.8; provided, that if any Guarantor has made payment to the Secured Parties of all or any part of the Obligations and the Loan Repayment Date has occurred, then, at such Guarantor’s request, the Administrative Agent (on behalf of the Secured Parties) will, at the expense of such Guarantor, execute and deliver to such Guarantor appropriate documents (without recourse and without representation or warranty) necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Obligations resulting from such payment. In furtherance of the foregoing, at all times prior to the Loan Repayment Date, each Guarantor shall refrain from taking any action or commencing any proceeding against any Obligor (or its successors or assigns, whether in connection with a bankruptcy proceeding or otherwise) to recover any amounts in respect of payments made under this Guaranty to any Secured Party, except as necessary to protect and maintain its future rights of collection in connection with applicable statutes of limitations.

SECTION 2.8. Payments; Application. Each Guarantor agrees that all payments made by such Guarantor hereunder will be made in Dollars to the Administrative Agent in immediately available funds, without set-off, counterclaim or other defense and in accordance with Sections 4.6 and 4.7 of the Credit Agreement, free and clear of and without deduction for any Taxes, each Guarantor hereby agreeing to comply with and be bound by the provisions of Sections 4.6 and 4.7 of the Credit Agreement in respect of all payments and application of such payments made by it hereunder and each Secured Party hereby agreeing to comply with and be bound by the

provisions of Sections 4.6 and 4.7 of the Credit Agreement in respect of all payments and application of payments received by such Secured Party and the provisions of which Sections are hereby incorporated into and made a part of this Guaranty by this reference as if set forth herein; provided, that references to the “Borrower” in such Sections shall be deemed to be references to each Guarantor, and references to “this Agreement” in such Sections shall be deemed to be references to this Guaranty.

SECTION 2.9. Waiver of Defenses. To the fullest extent permitted by applicable law, each Guarantor waives any defense based on or arising out of any defense of the Borrower or any other Guarantor or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrower or any other Guarantor, other than the indefeasible payment in full in cash of all the Obligations. The Administrative Agent and the other Secured Parties may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales (to the extent permitted by applicable law), accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Obligations, make any other accommodation with the Borrower or any Guarantor or exercise any other right or remedy available to them against the Borrower or any Guarantor, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Obligations have been fully and indefeasibly paid in full in cash. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against the Borrower or any other Guarantor, as the case may be, or any security.

SECTION 3.1. Credit Agreement Representations and Warranties. The representations and warranties contained in Article VI of the Credit Agreement, insofar as the representations and warranties contained therein are applicable to any Guarantor and its properties, are true and correct in all material respects, each such representation and warranty set forth in such Article (insofar as applicable as aforesaid) and all other terms of the Credit Agreement to which reference is made therein, together with all related definitions and ancillary provisions, being hereby incorporated into this Guaranty by this reference as though specifically set forth in this Article.

SECTION 3.2.

affairs of any other Obligor that might become known to any Secured Party at any time, whether or not such Secured Party knows or believes or has reason to know or believe that any such fact or change is unknown to such Guarantor, or might (or does) materially increase the risk of such Guarantor as guarantor, or might (or would) affect the willingness of such Guarantor to continue as a guarantor of the Obligations.

SECTION 3.3. Best Interests. It is in the best interests of each Guarantor to execute this Guaranty inasmuch as such Guarantor will, as a result of being a Subsidiary of the Borrower, derive substantial direct and indirect benefits from the Credit Extensions made from time to time to the Borrower by the Lenders and the Issuers pursuant to the Credit Agreement and the execution and delivery of Hedging Agreements among the Borrower, other Obligors and certain Secured Parties, and each Guarantor agrees that the Secured Parties are relying on this representation in agreeing to make Credit Extensions to the Borrower.

Each of the Guarantors acknowledges and agrees with the Administrative Agent that the Existing Guaranty is amended, restated and superseded in its entirety pursuant to the terms hereof. The execution and delivery of this Guaranty shall not constitute a novation of any obligations owing to the Lenders or the Administrative Agent under the Existing Guaranty based on facts or events occurring or existing prior to the execution and delivery of this Guaranty.
