A certificate of the amount of payment determined by the Substitute Evaluation Agent shall be conclusive and binding for all purposes, absent manifest error; and

21

     (ii) if the Borrower objects to the payment amount determined by such Tranche B Bank and by the Substitute Evaluation Agent or fails to pay such amount on the prepayment date, the Borrower shall not have the right to prepay such Tranche B Loan.

          (b) Mandatory. The Borrower shall, upon the occurrence of the Borrower ceasing to be Controlled by the Parent, prepay the aggregate principal amount of the Loans outstanding at such time.

A certificate as to the amount of such increased cost, submitted in good faith to the Borrower by such Lender, shall be conclusive and binding for all purposes, absent manifest error.

          (b) If any of the Lenders determines in good faith that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority enacted after the date of this Agreement (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender’s commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender, the Borrower shall pay to such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to lend hereunder. A certificate as to such amounts submitted to the Borrower by such Lender in good faith, shall be conclusive and binding for all purposes, absent manifest error.

          SECTION 2.10. Illegality. Notwithstanding any other provision of this Agreement, if any of the Lenders determines in good faith that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any of the Lenders or its Applicable Lending Office to perform its obligations hereunder to make Tranche A Loans, Tranche B Loans

22

or Tranche C Loans, as the case may be, or to fund or maintain any Loans to be made by it hereunder, such Lender shall forthwith give notice thereof to the Borrower and the Administrative Agent, whereupon (a) until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Tranche A Loans, Tranche B Loans or Tranche C Loans, as the case may be, shall be suspended and (b) if such Lender shall so request in such notice, the Borrower shall within 15 (fifteen) days of such notice, unless such law, regulation, central bank or governmental authority requires that prepayment shall occur immediately, prepay in full the then outstanding principal amount of such Tranche A Loan, Tranche B Loan or Tranche C Loan, as the case may be, together with accrued interest thereon. If it is lawful for such Lender to maintain any such Loan through the last day of the Interest Period then applicable to such Loan, such prepayment shall be due on such last day.

(Mexico City time) in the case of either the Tranche B Loans or Tranche C Loans, on the day when due (i) in the case of the Tranche A Loans, in U.S. Dollars and in the case of either the Tranche B Loans or Tranche C Loans, in Pesos, in all cases to the Administrative Agent, for the account of each of the Lenders, at the Administrative Agent’s Account in same day funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees or any other Obligation then payable hereunder and under the Notes to more than one Lender, to such Lenders for the account of their respective Applicable Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lenders and (ii) if such payment by the Borrower is in respect of any Obligation then payable hereunder to one Lender, to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date of such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to such Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

          (b) The Borrower hereby authorizes each Lender and each of its Affiliates, if and to the extent payment owed to such Lender is not made when due hereunder or, in the case of a Lender, under the Tranche A Note, Tranche B Note or Tranche C Note, as the case may be, held by such Lender, to charge from time to time, to the fullest extent permitted by law, against any or all of the Borrower’s accounts with such Lender or such Affiliate any amount so due.

          (c) All computations of interest based on the LIBO Rate, the TIIE Rate, the Fixed Rate and of facility fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or facility fees are payable. The

23

Administrative Agent shall determine each interest rate applicable to the Loans hereunder. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

          (d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of any Loan to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

          (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to any Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each such Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each such Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate in the case of Tranche A Loans, and the TIIE Rate in the case of Tranche B Loans and Tranche C Loans.

          SECTION 2.12. Taxes. (a) Any and all payments by the Borrower under the Loan Documents or any other documents to be delivered thereunder shall be made, in accordance with Section 2.12 or the applicable provisions of such other documents, free and clear of and without deduction for any and all present or future taxes (including, without limitation, value-added taxes and withholding taxes), levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of the Administrative Agent or any of the Lenders, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction under the laws of which the Administrative Agent or any of the Lenders is organized or any political subdivision thereof and taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction of the Administrative Agent or any of the Lenders’ Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments under the Loan Documents being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable under any of the Loan Documents, or any other documents to be delivered thereunder to the Administrative Agent or any of the Lenders, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12) the Administrative Agent or any Lender receives an amount equal to the sum it would have received had no such deductions been made (provided, however, that no such additional amounts shall be payable in respect of any taxes imposed by reason of the Administrative Agent or any Lender’s failure to comply with Section 2.12(d), in excess of the additional amounts that would have been payable had the Administrative Agent or any Lender

24

complied with such Section), (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or any other documents to be delivered hereunder or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes or any other documents to be delivered hereunder (hereinafter referred to as “Other Taxes”).

          (c) The Borrower shall indemnify the Administrative Agent or any of the Lenders for and hold them harmless against the full amount of Taxes or Other Taxes (including, without limitation, taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.12) imposed on or paid by the Administrative Agent or any of the Lenders and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date the Administrative Agent or any Lender (as the case may be) makes written demand therefor.

          (d) Each Lender (that is not a Mexican Financial Institution) hereby represents to the Borrower as of the date hereof that it is a foreign financial institution or export credit agency registered with the Ministry of Finance for purposes of Article 195-I or 196 of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta) and that it is a resident (or its principal office is a resident) in a country that has entered into a treaty for the avoidance of double taxation with Mexico. The Borrower shall not be obligated to pay the Administrative Agent or any Lender (that is not a Mexican Financial Institution) any amounts described in Section 2.12(a) in respect of Taxes that would not have been imposed but for the failure of the Administrative Agent or such Lender (that is not a Mexican Financial Institution) (i) prior to the last day of the first Interest Period (a) to be registered (or, with respect to any bank, export credit agency or other financial institution which becomes a Lender pursuant to Section 8.07, on the date such bank or other financial institution becomes a Lender) with the Ministry of Finance as a foreign financial institution or export credit agency for purposes of Article 195-I or 196 of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta) or any successor provisions and the regulations thereunder and (b) to be a resident (or to have the principal offices of such Lender be a resident, if such Lender lends through a branch or agency) for tax purposes of a jurisdiction with which Mexico has in effect a treaty for the avoidance of double taxation, (ii) to use its reasonable efforts (consistent with legal and regulatory restrictions) to maintain its registration with the Ministry of Finance as a foreign financial institution or export credit agency for purposes of Article 195-I or 196 of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta) or any successor provisions and the regulations thereunder, if the making of such filing would not, in the reasonable judgment of such Lender, be materially disadvantageous to such Lender or (iii) following a reasonable request of the Borrower upon 60 days’ written notice (unless a lesser period is reasonable under the circumstances), to complete and file with the appropriate Governmental Authority, such forms, certificates or documents (collectively, “Forms”) prescribed by law, rule or regulation enacted or issued by Mexico, or by a double taxation treaty to which Mexico is a party and which is in effect, that are necessary to avoid or reduce such Taxes pursuant to provisions of any law, rule or regulation enacted or issued by

25

Mexico, or a double taxation treaty to which Mexico is a party and which is in effect (provided that (i) such Lender shall be under no obligation to provide any information to the Borrower which such Lender deems, in such Lender’s judgment, to be confidential, (ii) such Lender or the Administrative Agent is legally entitled to complete, execute and deliver such Forms, (iii) the completion, execution and delivery of such Forms will not result, in the good faith, reasonable determination of such Lender or the Administrative Agent, made in writing to the Borrower, in the imposition on such Lender or the Administrative Agent of (1) any additional material legal or regulatory burden or (2) any additional material out-of-pocket costs or (3) any other material adverse consequences). Promptly upon written request by the Borrower, each Lender (that is not a Mexican Financial Institution) shall provide to the Borrower, to the extent it is so registered, evidence of its tax registration with the Ministry of Finance, in effect at the time of such request, in connection with Article 195-I or 196 of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta) and the regulations thereunder. For purposes of Section 2.12(d) (i) (b), the parties hereto hereby agree that if the Mexican Ministry of Finance or any other competent Mexican Governmental Authority determines, by means of a written resolution to such effect, or if the Borrower has reasonable grounds to believe, based on an opinion of counsel of recognized standing delivered to the Administrative Agent, that the Mexican withholding tax regime applicable to the branches or agencies of a Lender (that is not a Mexican Financial Institution) is different from the tax regime that would be applicable to the principal office of a Lender (that is not a Mexican Financial Institution), then the Borrower shall be entitled to request the relevant Lender, and the relevant Lender shall use its reasonable efforts to change its Applicable Lending Office to a jurisdiction with which Mexico shall have entered into a treaty for the avoidance of double taxation, and if the Lender (that is not a Mexican Financial Institution) shall fail to do so within a sixty (60) day period, the Borrower would be entitled to (x) prepay the Loans of such Lender in accordance with the prepayment terms contemplated herein (without the relevant Lender being obligated to observe the sharing provisions referred to in Section 2.09) or (y) cause a Lender or third party to purchase the relevant Loan, at par plus accrued and unpaid interest to such date plus any applicable funding breakage costs set forth in Section 2.02.

          (e) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Administrative Agent for its own account or for the account of such Lender, as the case may be, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment. In the case of any payment hereunder or under the Notes or any other documents to be delivered hereunder by or on behalf of the Borrower, if the Borrower determines that no Taxes or Other Taxes are payable in respect thereof, the Borrower shall, at the request of the Administrative Agent or any of the Lenders, furnish, or cause the payor to furnish, to the Administrative Agent or such Lender, as the case may be, an opinion of counsel acceptable to the Administrative Agent or such Lender stating that such payment is exempt from Taxes or Other Taxes.

          (f) The obligations of the Borrower contained in this Section 2.12 shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable under the Loan Documents.

          (g) In the event that an additional payment is made under this Section 2.12 (a), (b) or (c) for the account of any Lender and such Lender, in its sole discretion, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or

26

repayment of, any tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such payment, such Lender shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as such Lender shall, in its sole discretion, have determined to be attributable to such deduction or withholding and which will leave such Lender (after such payment) in no worse position than it would have been in if the Borrower had not been required to make such deduction or withholding, provided that the Borrower, upon the request of such Lender agrees to repay the amount paid over to it (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the such Lender in the event such Lender is required to repay such refund to such Governmental Authority. Nothing herein contained shall interfere with the right of a Lender to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Lender to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled.

          SECTION 2.13. Use of Proceeds. The proceeds of the Loans shall be available (and the Borrower agrees that it shall use such proceeds) for the Borrower’s general corporate purposes, including spectrum acquisition and capital expenditures.

          SECTION 2.14. Notes. (a) The Borrower will execute and deliver to the Administrative Agent for the account of each Tranche A Bank one or more duly executed promissory note(s) (pagaré) of the Borrower guaranteed (por aval) by the Subsidiary Guarantors, dated the relevant Funding Date evidencing such Tranche A Loan made on such Funding Date by such Tranche A Bank, substantially in the form of Exhibit A (each, a “Tranche A Note” and, collectively, the “Tranche A Notes”), payable to the order of such Tranche A Bank and in a principal amount equal to such Tranche A Loan made on such Funding Date.

          (b) The Borrower will execute and deliver to the Administrative Agent for the account of each Tranche B Bank one or more duly executed promissory note(s) (pagaré) of the Borrower guaranteed (por aval) by the Subsidiary Guarantors, dated the relevant Funding Date evidencing such Tranche B Loan made on such Funding Date by such Tranche B Bank, substantially in the form of Exhibit B (each, a “Tranche B Note” and, collectively, the “Tranche B Notes”, payable to the order of such Tranche B Bank and in a principal amount equal to such Tranche B Loan made on such Funding Date.

          (c) The Borrower will execute and deliver to the Administrative Agent for the account of each Tranche C Bank one or more duly executed promissory note(s) (pagaré) of the Borrower guaranteed (por aval) by the Subsidiary Guarantors, dated the relevant Funding Date evidencing such Tranche C Loan made on such Funding Date by such Tranche C Bank, substantially in the form of Exhibit C (each, a “Tranche C Note” and, collectively, the “Tranche C Notes” and, together with the Tranche A Notes and the Tranche B Notes, the “Notes”), payable to the order of such Tranche C Bank and in a principal amount equal to such Tranche C Loan made on such Funding Date.

27

          (d) Promptly upon (i) substitution of the LIBO Rate in accordance with the provisions of Section 2.07 hereof and/or (ii) the election of the Borrower to change the duration of an Interest Period for a Tranche A Loan in accordance with the terms set forth in this Agreement, the Borrower and each Subsidiary Guarantor (por aval) shall execute and deliver to the Administrative Agent for the account of each Tranche A Bank, at the Administrative Agent’s request, in exchange for the Notes evidencing the relevant Loans of such Tranche A Bank theretofore delivered to such Tranche A Bank, a new Tranche A Note in substantially the form of Exhibit A payable to such Tranche A Bank, dated the date of such Tranche A Note being exchanged, in a principal amount equal to the principal amount then outstanding of such Tranche A Note and otherwise duly completed.

          SECTION 2.15. Sharing of Payments, Etc. If any Lender shall obtain at any time any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise, other than as a result of an assignment pursuant to Section 8.07) (a) on account of Obligations due and payable to such Lender hereunder and under the Notes at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations due and payable to all Lenders hereunder and under the Notes at such time) of payments on account of the Obligations due and payable to all Lenders hereunder and under the Notes at such time obtained by all of the Lenders at such time or (b) on account of Obligations owing (but not due and payable) to such Lender hereunder and under the Notes at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing to such Lender at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lenders hereunder and under the Notes at such time) of payments on account of the Obligations owing (but not due and payable) to all Lenders hereunder and under the Notes at such time obtained by all of the Lenders at such time, such Lender shall forthwith purchase from the other Lenders such interests or participating interests in the Obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each other Lender shall be rescinded and such other Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (i) the purchase price paid to such Lender to (ii) the aggregate purchase price paid to all Lenders) of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such other Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. For the purposes of this Section 2.15, the respective ratable shares shall be determined by the Administrative Agent by converting both the Tranche B Loans and the Tranche C Loans into Dollars based on the USD Equivalent thereof as of the Closing Date. The Borrower agrees that any Lender so purchasing an interest or participating interest from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such interest or participating interest, as the case may be, as fully as if such Lender were the direct creditor of the Borrower in the amount of such interest or participating interest, as the case may be.

     (e) The Consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2003, and the related Consolidated statements of income and cash flows of the Borrower and its Subsidiaries for the fiscal year then ended, accompanied by an opinion of PricewaterhouseCoopers, independent public accountants, and the Consolidated balance sheet of the Borrower and its Subsidiaries as at June 30, 2004, and the related Consolidated statements of income and cash flows of the Borrower and its Subsidiaries for the six months then ended, duly certified by the chief financial officer of the Borrower, copies of which have been furnished to the Lender, are complete and correct and fairly present, subject, in the case of said balance sheet as at June 30, 2004, and said statements of income and cash flows for the six months then ended, to year-end audit adjustments, the Consolidated financial condition of the Borrower and its Subsidiaries as at such dates and the Consolidated results of operations of the Borrower and its Subsidiaries for the periods ended on such dates, all in accordance with Mexican GAAP; provided, however, that until the initial Funding Date the foregoing representation is subject to the qualification that the Borrower has acknowledged the lack of proper reconciliation of certain of its liability accounts with its books and records, that such reconciliation is undergoing continuing review, and that such lack of reconciliation may have resulted in understatements of income in some fiscal quarters and overstatements of income in other fiscal quarters going back to the fiscal year ended December 31, 2002, all as described in the Accounting Memo, which the Borrower and

33

its auditors reasonably believe are not material. Since December 31, 2003, there has been no Material Adverse Change.

     (f) There is no pending or to the best knowledge of the Borrower or its Material Subsidiaries, threatened action, suit, investigation, litigation or proceeding (including, without limitation, any Environmental Action) affecting any Loan Party or any of its Subsidiaries before any court, governmental agency or arbitrator that (i) if adversely determined, would be likely to have a Material Adverse Effect, except as disclosed in Schedule 3.01(d) or (ii) purports to affect the legality, validity or enforceability of any Loan Documents, or the consummation of the transactions contemplated hereby.

     (g) The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U issued by the Board of Governors of the U.S. Federal Reserve System), and no proceeds of the Loans will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock.

     (h) Each Loan Party and each of their respective Subsidiaries has filed, has caused to be filed or has been included in all tax returns (national, departmental, local, municipal and foreign) required to be filed and has paid all taxes, assessments, fees, related liabilities and other charges (including interest and penalties) due with respect to the years covered by such returns, except where such taxes or liabilities are being contested in good faith and by proper proceedings.

     (i) Each Loan Party and each of their respective Subsidiaries is in material compliance with all applicable laws, ordinances, rules, regulations and requirements of all governmental authorities (including, without limitation, all governmental licenses, certificates, permits, franchises and other governmental authorizations and approvals, (including, without limitation, the Concession Titles) necessary to the ownership of its properties or to the conduct of its business, Environmental Laws, and laws with respect to social security and pension fund obligations, final judgments and court orders.)

     (j) Set forth on Schedule 4.01(j) hereto is a complete and accurate list of all Material Contracts of the Borrower and its Subsidiaries, showing as of the date hereof the parties, subject matter and term thereof. Each such Material Contract has been duly authorized, executed and delivered by all parties thereto, has not been amended or otherwise modified in any material respect, is in full force and effect and is binding upon and enforceable against all parties thereto in accordance with its terms, and there exists no default by the Borrower under or with respect to any of its material contractual obligations in any Material Contract that could reasonably be expected to have a Material Adverse Effect.

     (k) To the best of any Loan Party’s knowledge, no income, stamp or other taxes (other than taxes on, or measured by, net income or net profits) or levies, imposts, deductions, charges, compulsory loans or withholdings whatsoever are or will be, under applicable law in Mexico, imposed, assessed, levied or collected by Mexico or any political subdivision or taxing authority thereof or therein either (i) on or by virtue of the

34

execution, delivery, performance, enforcement or admissibility into evidence of any Loan Document or (ii) on any payment to be made by any Loan Party pursuant to any Loan Document other than withholding taxes payable by any Loan Party pursuant to any Loan Document on payments of interest, commissions and fees, made by any Loan Party to a non resident of Mexico for tax purposes.

     (l) Each Loan Party is subject to civil and commercial law with respect to its obligations under each Loan Document to which it is party, and the execution, delivery and performance by such Loan Party of each Loan Document to which it is party constitute private and commercial acts (jure gestionis acts) rather than public or governmental acts (jure imperii acts). None of the Loan Parties or any of their Subsidiaries or any of their respective properties has any immunity from jurisdiction of any court or from set-off or any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) under the laws of Mexico. Each Loan Party’s choice of governing law as New York law and its consent to submission to the jurisdiction of New York federal and state courts under the Loan Documents is legal, valid and binding under Mexican Law.

     (m) The obligations of the Borrower and each of its Subsidiaries under the Loan Documents constitute direct, unconditional, unsubordinated and unsecured obligations of the Borrower and its Subsidiaries and do rank and will rank pari passu in priority of payment and in all other respects with all other present and future senior unsecured Debt of the Borrower and such Subsidiaries.

     (n) Each Loan Document is in proper legal form under the law of Mexico for the enforcement thereof against each Loan Party which is party thereto under the law of Mexico; and to ensure the legality, validity, enforceability or admissibility in evidence of each such Loan Document in Mexico it is not necessary that any such Loan Document or any other document be registered, filed or recorded with any court or other authority in Mexico or that any stamp or similar tax be paid on or in respect of any Loan Document, except that in the event that any legal proceedings with respect to any Loan Document are brought in the courts of Mexico, a Spanish translation of the document required in such proceedings prepared by a Mexican court-approved translator would have to be approved by the court after the defendant had been given an opportunity to be heard with respect to the accuracy of such translation, and the proceedings would thereafter be based upon the translated documents. Any judgment against any Loan Party of a state or United States federal court in the State of New York, United States is capable of being enforced in the courts of Mexico; except that if any legal proceedings for the enforcement of such judgment are brought in the courts of Mexico, a Spanish translation of such judgment prepared by a Mexican court-approved translator would have to be approved by the court after the defendant has been given an opportunity to be heard with respect to the accuracy of the translation, and the proceedings would thereafter be based on the translated judgment. There is no requirement for the Administrative Agent, nor any Lender, to be licensed or qualified with any governmental authority solely by reason of the execution and performance of the Loan Documents.

     (o) The Borrower, a nonbank entity located outside the United States, understands that it is the policy of the Board of Governors of the U.S. Federal Reserve System that extensions of credit by international banking facilities (as defined in Section 204.8(a) of Regulation D) may be used only to finance the non-U.S. operations of a customer (or its foreign affiliates) located outside the United States as provided in Section 204.8(a)(3)(vi) of Regulation D. Therefore, the Borrower acknowledges that the proceeds of the Loans by the international banking facility of any of the Lenders (as defined in Section 204.8(a) of Regulation D) will be used solely to finance the Borrower’s operations outside the United States or that of the Borrower’s foreign affiliates.

Each of the Lenders hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement and the Notes as are delegated to the Administrative Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is contrary to this Agreement or applicable law. The Administrative Agent agrees to give to each of the Lenders prompt notice of each notice given to it by the Borrower pursuant to the terms of this Agreement.

          SECTION 7.02. Delegation of Duties. The Administrative Agent may execute any of its duties under the Loan Documents by and through agents, attorneys in fact or affiliates.

          SECTION 7.03. Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Tranche A Note, Tranche B Note or Tranche C Note as the holder thereof until the Administrative Agent receives and accepts an Assignment and Acceptance entered into by such Lender that is the payee of such Tranche A Note, Tranche B Note or Tranche C Note, as the case may be, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (b) may consult with legal counsel (including counsel for the Loan Parties or of any Lender), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any of the Lenders and shall not be responsible to any of the Lenders for any statements, warranties or representations (whether written or oral) made in or in connection with the Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any Loan Document on the part of any Loan Party or to inspect the property (including the books and records) of any Loan Party; (e) shall not be responsible to any of the Lenders for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, any Loan Document or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, telecopy or telex) believed by it to be genuine and signed or sent by the proper party or parties.

          SECTION 7.04. Citibank, N.A. and Affiliates. With respect to its Commitments, the Loans made by it and the Notes issued to it, Citibank, N.A. shall have the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though it were not an Administrative Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Citibank, N.A. in its individual capacity. Citibank, N.A. and its

48

affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, any Loan Party, any of its Subsidiaries and any Person that may do business with or own securities of such Loan Party or any such Subsidiary, all as if Citibank, N.A. was not the Administrative Agent, and without any duty to account therefor to the Lenders.

          SECTION 7.05. Lender Credit Decision. Each of the Lenders acknowledges that it has, independently and without reliance upon the Administrative Agent or any of the Lenders and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

          SECTION 7.06. Indemnification. (a) Each Lender severally agrees to indemnify the Administrative Agent (to the extent not promptly reimbursed by the Borrower) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Administrative Agent under the Loan Documents (collectively, the “Indemnified Costs”); provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Administrative Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.06 applies whether any such investigation, litigation or proceeding is brought by any of the Lenders or any other Person.

          (b) For purposes of this Section 7.06, the Lenders’ respective ratable shares of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Loans outstanding at such time and owing to the respective Lenders, and (ii) the aggregate unused portions of their respective Commitment at such time; provided, however, that the respective ratable shares shall be determined by the Administrative Agent by converting the Tranche B Loans or the Tranche C Loans, as the case may be, into Dollars based on the USD Equivalent thereof as of the Closing Date. The failure of any Lender to reimburse the Administrative Agent promptly upon demand for its ratable share of any amount required to be paid by the Lenders to the Administrative Agent as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Administrative Agent for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Administrative Agent for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and

49

obligations of each Lender contained in this Section 7.06 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

          SECTION 7.07. Successor Agents. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of all of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation or removal under this Section 7.07 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (a) the retiring Administrative Agent’s resignation or removal shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent shall have become effective, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

          (b) The obligations of the Borrower in respect of any sum due to any of the Lenders hereunder or under the Notes shall, notwithstanding any judgment in a currency other than U.S. Dollars, be discharged only to the extent that, on the Business Day following receipt by the Lenders of any sum adjudged to be so due in such other currency, any of the Lenders may, in accordance with normal, reasonable banking procedures, purchase U.S. Dollars with such other currency. If the amount of U.S. Dollars so purchased is less than the sum originally due to any of the Lenders, in U.S. Dollars, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Lenders against such loss.

          SECTION 8.13. Waiver of Jury Trial.
