(ii) Tranche B Loans. Each Tranche B Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal at all times during such Interest Period for such Tranche B Loan to the sum of (x) the Fixed Rate plus (y) the Applicable Margin computed on the basis of a 360-day year for actual days elapsed, payable in arrears on the last day of such Interest Period.

(iii) Tranche C-1 Loans and Tranche C-2 Loans. Each Tranche C-1 Loan and each Tranche C-2 Loan respectively shall bear interest for each day during each Interest

Upon the occurrence and during the continuance of any Event of Default, the Borrower shall pay interest (“Default Interest”) on the outstanding principal amount owing to each Lender, payable in arrears on the dates referred to in clause (a)(i), (a)(ii) or (a)(iii) above and on demand, at a rate per annum equal at all times (i) in the case of Tranche A-1 Loans, Tranche A-2 Loans and Tranche A-3 Loans, to 2% per annum above the rate per annum required to be paid on such Loan pursuant to clause (a)(i) above, (ii) in the case of the Tranche B Loans, to a rate equal to the TIIE Rate in effect at such time, plus the rate per annum required to be paid on such Loan pursuant to clause (a)(ii) above and (iii) in the case of the Tranche C-1 Loans and Tranche C-2 Loans, to a rate equal to the TIIE Rate in effect at such time, plus the rate per annum required to be paid on such Loan pursuant to clause (a)(iii) above.

SECTION 2.07. Interest Rate Determination. With respect to the Tranche A-1 Loans, the Tranche A-2 Loans and the Tranche A-3 Loans, if the Required Lenders determine that the LIBO Rate for any Interest Period for any such loan will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Tranche A-1 Loans, Tranche A-2 Loans and/or Tranche A-3 Loans as the case may be, for such Interest Period, such Required Lenders shall forthwith so notify the Administrative Agent. During the 15 days next succeeding the giving of such notice, the Borrower and the Administrative Agent shall negotiate in good faith in order to arrive at a mutually satisfactory interest rate which shall be applicable during such Interest Period to such Loan. If within such 15-day period, the Borrower and the Administrative Agent agree in writing upon an alternative interest rate, such rate shall be effective from the commencement of such Interest Period. If the Borrower and the Administrative Agent fail to agree upon such an alternative interest rate within such 15-day period, the interest rate during such Interest Period applicable to such loan effective from the commencement of such Interest Period shall be such rate as the Administrative Agent shall determine (in a certificate delivered by the Administrative Agent to the Borrower setting forth the basis of the computation of such amount, which certificate shall be conclusive and binding for all purposes, absent manifest error) to be necessary to compensate the Lender for its cost of obtaining (in good faith and using commercially reasonable efforts to minimize the interest cost to the Borrower) as of the commencement of such Interest Period funds for such Interest Period in an amount equal to the principal amount of such Tranche A-1 Loan, such Tranche A-2 Loan and/or such Tranche A-3 Loan as the case may be, plus the Applicable Margin. The Administrative Agent shall notify the Borrower of each such determination as promptly as practicable.

SECTION 2.08. Prepayments. (a) Optional.

Prepayments of Tranche A-1 Loans, Tranche A-2 Loans and Tranche A-3 Loans shall be made ratably with respect to the Tranche A-1 Loans, Tranche A-2 Loans and Tranche A-3 Loans. Each principal portion of any prepayment of a Tranche B Loan, Tranche C-1 Loan or a Tranche C-2 Loan shall be applied to the principal installments due hereunder in inverse order of maturity; provided further that in the case of the prepayment of any Tranche B Loan, the Borrower shall pay on the date of such prepayment all break funding costs previously evidenced to the Borrower in reasonable detail by the relevant Tranche B Bank; provided that, the basis for the calculation of any amounts that any Tranche B Bank is entitled to receive pursuant to this proviso shall be the present value, calculated as of the scheduled prepayment date, of the future payments on such Tranche B Loan through maturity of such Loan, at a discount rate (the “Discount Rate”) equal to the rate determined by the Administrative Agent in consultation with the Tranche B Banks pursuant to the derivatives transactions evaluation model in the market, which takes into account financial market practice and the standard rules applied by Banco de México, as such methodology is described on Schedule 2.08(a); provided, however:

(i) in the event that the Borrower does not agree with the amount that such Tranche B Bank is entitled to receive as determined pursuant to the methodology referred to above, the Borrower shall within two Business Days of notice of such amount, send a notice to such Tranche B Bank indicating the specific reasons for its disagreement. Such Tranche B Bank shall then select a Substitute Evaluation Agent to calculate the amount that such Tranche B Bank is entitled to receive using the same methodology previously described to the Borrower by such Tranche B Bank. 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

(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.

SECTION 2.09. Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law) after the date of this Agreement, there shall be any increase in the cost to any of the Lenders of agreeing to make or making, funding or maintaining its Tranche A-1 Loans, Tranche A-2 Loans, Tranche A-3 Loans, Tranche B Loans, Tranche C-1 Loans or Tranche C-2 Loans, as the case may be, (excluding for purposes of this Section 2.09 any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.12 shall govern), and (y) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by any of the Lenders, pay to such Lender additional amounts sufficient to compensate such Lender for such increased cost; provided, however, that before making any such demand, each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 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-1 Loans, Tranche A-2 Loans, Tranche A-3 Loans, Tranche B Loans, Tranche C-1 Loans or Tranche C-2 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-1 Loans, Tranche A-2 Loans, Tranche A-3 Loans, Tranche B Loans, Tranche C-1 Loans or Tranche C-2 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-1 Loan, Tranche A-2 Loan, Tranche A-3 Loan,Tranche B Loan, Tranche C-1 Loan or Tranche C-2 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.

SECTION 2.11. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the Notes, irrespective of any right of counterclaim or set-off, not later than 11:00 A.M. (New York City time) in the case of Tranche A-1 Loans, Tranche A-2 Loans or Tranche A-3 Loans, and 11:00 A.M. (Mexico City time) in the case of either the Tranche B Loans, the Tranche C-1 Loans or the Tranche C-2 Loans, on the day when due (i) in the case of the Tranche A-1 Loans, the Tranche A-2 Loans or Tranche A-3 Loans, in U.S. Dollars and in the case of either the Tranche B Loans, the Tranche C-1 Loans or the Tranche C-2 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-1 Note, Tranche A-2 Note, Tranche A-3 Note, Tranche B Note, Tranche C-1 Note or Tranche C-2 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 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. All prepayments of principal shall be made together with accrued interest to the date of such prepayment on the principal amount prepaid.

(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-1 Loans, Tranche A-2 Loans and Tranche A-3 Loans, and the TIIE Rate in the case of Tranche B Loans, Tranche C-1 Loans and Tranche C-2 Loans.

(f) At the request of the Borrower, each Lender which is a Mexican Financial Institution shall deliver to the Borrower an invoice for any interest payments, including Default Interest made hereunder, which invoice shall be issued in accordance with all applicable tax and legal requirements.

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 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 or an Export Credit Agency hereby represents to the Borrower as of the date hereof that it is a foreign financial institution registered with the Registry of Foreign Banks, Financial Entities, Pension and Retirement Funds and Investment Funds (Registro de bancos, entidades de financiamiento, fondos de pensiones y jubilaciones y fondos de inversión del extranjero) maintained by the Ministry of Finance for purposes of Article 195- I, subsection a), item 2 of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta)(or any successor provisions) 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 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 for purposes of Article 195-I subsection a), item 2 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 for purposes of Article 195-I subsection a), item 2 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 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 or an Export Credit Agency) 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 subsection a), item 2 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 or an Export Credit Agency) is different from the tax regime that would be applicable to the principal office of a Lender (that is not a Mexican Financial Institution or an Export Credit Agency), 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 or an Export Credit Agency) 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 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.

(h) Each Lender, other than a Mexican Financial Institution or an Export Credit Agency, from time to time, but at least 10 Business Days before the next succeeding date upon which a payment is due hereunder, will notify the Borrower if such Lender fails to maintain residency requirements as provided in Section 2.12(d) hereof.

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 the Tranche B Loans, the Tranche C-1 Loans and the Tranche C-2 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.

SECTION 2.16. Tranche A-3 Commitments (a) The Borrower may, at any time but in any event not more than once in any calendar year, prior to the Maturity Date for the Tranche A Loans, by notice to the Administrative Agent, request that the Lenders make a further commitment in the aggregate amount of $25,000,000 or an integral multiple of $5,000,000 in excess thereof (each a “Commitment Increase”, and the sum of all Commitment Increases at any given time being the “Tranche A-3 Commitments”) to be effective as of a date that is at least 90 days prior to the scheduled Maturity Date for the Tranche A Loans then in effect (the “Increase Date”) as specified in the related notice to the Administrative Agent; provided however that on the date of any request by the Borrower for a Commitment Increase and on the related Increase Date the applicable conditions set forth in Article III shall be satisfied.

(b) The Administrative Agent shall promptly notify the Lenders of a request by the Borrower for a Commitment Increase, which notice shall include (i) the proposed amount of such requested Commitment Increase, (ii) the proposed Increase Date and (iii) the date (which shall be earlier than the Increase Date) by which Lenders wishing to participate in the Commitment Increase must commit to an increase in the amount of their commitments (the “Commitment Date”). Each Lender that is willing to participate in such requested Commitment Increase (each an “Increasing Lender”) shall, in its sole discretion, give written notice to the Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its commitment. If the Lenders notify the Administrative Agent that they are willing to increase the amount of their respective commitments by an aggregate amount that exceeds the amount of the requested Commitment Increase, the requested Commitment Increase shall be allocated among the Lenders willing to participate therein in such amounts as are agreed between the Borrower and the Administrative Agent.

(c) Promptly following each Commitment Date, the Administrative Agent shall notify the Borrower as to the amount, if any, by which the Lenders are willing to participate in the requested Commitment Increase. If the aggregate amount by which the Lenders are willing to participate in any requested Commitment Increase on any such Commitment Date is less than the requested Commitment Increase, then the Borrower may extend offers to one or more Eligible Assignees to participate in any portion of the requested Commitment Increase that has not been committed to by the Lenders as of the applicable Commitment Date; provided,

however, that the Tranche A-3 Commitment of each such Eligible Assignee shall be in an amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof.

(d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a requested Commitment Increase in accordance with Section 2.16(b) (each such Eligible Assignee, an “Assuming Lender”) shall become a Lender party to this Agreement as of such Increase Date and the Tranche A-3 Commitment of each Increasing Lender for such requested Commitment Increase shall be so increased by such amount (or by the amount allocated to such Lender pursuant to the last sentence of Section 2.16(b)) as of such Increase Date; provided, however, that the Administrative Agent shall have received on or before such Increase Date the following, each dated such date:

(i) an opinion of counsel for the Borrower, in substantially the form of Exhibit H hereto;

(ii) an assumption agreement from each Assuming Lender, if any, in form and substance reasonably satisfactory to the Borrower and the Administrative Agent (each an “Assumption Agreement”), duly executed by such Eligible Assignee, the Administrative Agent and the Borrower; and

(iii) confirmation from each Increasing Lender of the increase in the amount of its Tranche A-3 Commitment in a writing reasonably satisfactory to the Borrower and the Administrative Agent.

On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding sentence of this Section 2.16(d), the Administrative Agent shall notify the Lenders (including, without limitation, each Assuming Lender) and the Borrower, on or before 1:00 P.M. (New York City time), by telecopier, of the occurrence of the Commitment Increase to be effected on such Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and each Assuming Lender on such date. Each Increasing Lender and each Assuming Lender (together, the “Tranche A-3 Banks”) shall, before 2:00 P.M. (New York City time) on the Increase Date, make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, in the case of such Assuming Lender, an amount equal to such Assuming Lender’s ratable portion of the Borrowings then outstanding (calculated based on its Tranche A-3 Commitment as a percentage of the aggregate Tranche A-3 Commitments outstanding after giving effect to the relevant Commitment Increase) and, in the case of such Increasing Lender, an amount equal to the excess of (i) such Increasing Lender’s ratable portion of the Borrowings then outstanding (calculated based on its Tranche A-3 Commitment as a percentage of the aggregate Tranche A-3 Commitments outstanding after giving effect to the relevant Commitment Increase) over (ii) such Increasing Lender’s ratable portion of the Borrowings then outstanding (calculated based on its Tranche A-1 Commitment as a percentage of the aggregate Tranche A-1 Commitments). After the Administrative Agent’s receipt of such funds from each such Increasing Lender and each such Assuming Lender, the Administrative Agent will promptly thereafter cause to be distributed like funds to the other Lenders for the account of their respective Applicable Lending Offices in an amount to each other Lender such that the aggregate amount of the outstanding Tranche A-3 Loans owing to each Lender after giving effect to such distribution equals such Lender’s ratable

portion of the Borrowings then outstanding (calculated based on its Tranche A-3 Commitment as a percentage of the aggregate Tranche A-3 Commitments).

(e) The Consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2005, 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 March 31, 2006, and the related Consolidated statements of income and cash flows of the Borrower and its Subsidiaries for the three 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 March 31, 2006, and said statements of income and cash flows for the three 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. Since December 31, 2005, 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(c) 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.

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, entered into after October 27, 2004 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.

(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.

(p) Neither the Borrower nor any of its Subsidiaries is an “investment company”, or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended.

(q) No information, exhibit or report furnished by or on behalf of any Loan Party to all of the Lenders in connection with the negotiation of any Loan Document or pursuant to the terms of any Loan Document contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein not misleading.

(r) There are no strikes, slowdowns or work stoppages, and, to the best knowledge of the Borrower, none is currently threatened, by the employees of the Borrower or any of its Material Subsidiaries that could reasonably be expected to have a Material Adverse Effect.

(s) Set forth on Schedule 4.01(s) hereto is a complete and accurate list of all patents, trademarks, trade names, service marks and copyrights, and all applications

therefor and licenses thereof, of the Borrower or any of its Subsidiaries filed, registered or granted after October 27, 2004, showing as of the date hereof the jurisdiction in which registered, the registration number, the date of registration and the expiration 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 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.

The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, and the Lenders shall treat each Person whose

name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time from time to time upon reasonable prior notice.

(e) The Lenders may sell participations to one or more banks or other entities (other than any Loan Party or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, any Loans owing to it and the Tranche A-1 Notes, Tranche A-2 Notes, Tranche A-3 Notes, Tranche B Notes, Tranche C-1 Notes or Tranche C-2 Notes, as the case may be, or Notes held by it); provided, however, that (i) each of the Lenders’ obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) each of the Lenders shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) each of the Lenders shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrower shall continue to deal solely and directly with the Lenders in connection with the Lenders’ rights and obligations under this Agreement and (v) no participant under any such participation shall have any rights, claims or causes of action against the Borrower, any Subsidiary or Affiliates or the Administrative Agent or any right to approve any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any other amounts payable hereunder, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Notes or any other amounts payable hereunder, in each case to the extent subject to such participation.

(f) Each of the Lenders may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to any of the Lenders by or on behalf of the Borrower upon delivery to the Borrower by such assignee, participant or proposed assignee or participant of a confidentiality agreement in the form attached hereto as Exhibit G.

(g) Notwithstanding any other provision set forth in this Agreement, any of the Lenders may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Loans owing to it and any Note held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the U.S. Federal Reserve System.

SECTION 8.08. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 8.09. Confidentiality. (a) Each of the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent, the Documentation Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent requested by

any regulatory authority; (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process or, in the case of Export Development Canada, in accordance with its internal disclosure policies; (d) to any other party to this Agreement; (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder; (f) subject to confidentiality or non-disclosure agreement containing provisions substantially the same as those of this Section 8.09 and substantially in the form of Exhibit G hereto to (i) any purchaser or assignee of or participant in or any prospective purchaser or assignee of or participant in, any of its rights or obligations under this Agreement or (ii) any direct or indirect contractual counterparty or prospective counterparty (or such contractual counterparty’s or prospective counterparty’s professional advisor) to any credit derivative transaction relating to the Obligations; (g) with the consent of the Parent; (h) to the extent such Information (i) becomes publicly available other than as result of a breach of this Section 8.09 or (ii) becomes available to the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent, the Documentation Agent or any Lender on a non-confidential basis from a source other than the Parent or its Subsidiaries; or (j) to any nationally recognized rating agency that requires access to information about a Lender’s or its Affiliates’ investment portfolio in connection with ratings issued with respect to such Lender or its Affiliates. To the extent that disclosure of any Information is required pursuant to clause (b) or (c) above, so long as any of the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent, the Documentation Agent or the Lender is not prohibited from so doing by any applicable laws, rules, regulations, final judgments or court orders, such Administrative Agent, Bookrunners, Lead Arranger, Syndication Agent, Documentation Agent or Lender will notify the Borrower thereof in writing at its address for notices set forth in the Credit Agreement Section 8.02(a), provided that the Borrower shall have no right to seek any action or remedy or have any claim or cause of action against any of the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent, the Documentation Agent or the Lenders in the event that such Administrative Agent, Bookrunners, Lead Arranger, Syndication Agent, Documentation Agent or Lender, as the case may be, shall fail to so notify to the Borrower. For the purposes of this Section, “Information” means all information furnished by the Borrower or any of its Subsidiaries to any Lender, the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent or the Documentation Agent relating to the Parent and its Subsidiaries or their business, other than any such information that is available to the Administrative Agent, the Bookrunners, the Lead Arranger, the Syndication Agent, the Documentation Agent or any Lender on a non-confidential basis prior to disclosure by the Parent and it Subsidiaries. Any Person required to maintain the confidentiality of Information as provided in this Section 8.09, shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information, which in no event shall be less than a reasonable degree of care.

(k) The undertakings of this Section 8.09 shall survive the termination of the Loan Documents and/or the Facility.

SECTION 8.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page

to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.11. Jurisdiction; Waiver of Immunities. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the jurisdiction of any New York State court or federal court of the United States sitting in New York City, and any appellate court from any thereof and to the courts of its own corporate domicile in respect of actions brought against it as a defendant, in any action or proceeding arising out of or relating to this Agreement or the Notes, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) The Borrower hereby irrevocably appoints CT Corporation System with an office on the date hereof at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, as its agent to receive on behalf of the Borrower and its property service of copies of the summons and complaint and any other process which may be served in any such action or proceeding. Such service may be made by mailing or delivering a copy of such process to the Borrower in care of the Process Agent at the Process Agent’s above address, and the Borrower hereby irrevocably authorizes and directs the Process Agent to receive such service on its behalf and forward such service to the Borrower. As an alternative method of service, the Borrower also irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to the Borrower at its address specified in Section 8.02.

(c) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court and for purposes of the submission to jurisdiction agreed in paragraph (a) above, to the forum to which it may be entitled to pursuant to applicable law.

(d) To the extent that the Borrower has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process in the U.S. or Mexico (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, the Borrower hereby irrevocably and unconditionally waives such immunity in respect of its obligations under this Agreement and the Notes and, without limiting the generality of the foregoing, agrees that the waivers set forth in this subsection (d) shall have the fullest scope permitted under the Foreign Sovereign Immunities Act of 1976 of the United States and are intended to be irrevocable for purposes of such Act.

(e) For purposes of notices in Mexico in the event of lawsuits and collections, the Borrower hereby irrevocably designates the following domicile:

Blvd. ▇. ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇. ▇▇, ▇▇.

▇▇▇▇▇▇, ▇.▇. ▇▇▇▇▇▇

Attention: Vice President and General Counsel

(f) Nothing in this Section 8.11 shall affect the right of any of the Lenders to serve legal process in any other manner permitted by law or affect the right of any of the Lenders to bring any action or proceeding against the Borrower or its property in the courts sitting in Mexico.

SECTION 8.12. Judgment Currency. (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or under the Notes in U.S. Dollars into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Lenders could purchase U.S. Dollars with such other currency in New York City on the Business Day preceding that on which final, non-appealable judgment is given.

(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. EACH OF THE BORROWER AND EACH OF THE LENDERS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE NOTES OR THE ACTIONS OF THE LENDERS IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

SECTION 8.14. Patriot Act Notice. Each Lender to which the Patriot Act applies and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

SECTION 8.15. No Novation, Etc.

(a) The terms and conditions of the Original Agreement are amended as set forth herein, and restated in their entirety and superseded by, this Agreement. Nothing in this Agreement shall be deemed to be a novation (novación) of any of the obligations under the Original Agreement. Notwithstanding any provision of this Agreement or any other document or instrument executed in connection herewith, the execution and delivery of this Agreement and the incurrence of obligations hereunder shall be in substitution for, but not in payment of, the obligations owed by the Loan Parties under the Original Agreement.

(b) From and after the execution of this Agreement, each reference to the “Agreement”, “Credit Agreement” or other reference originally applicable to the Original Agreement contained in any Loan Document shall be a reference to this Agreement, as amended, supplemented, restated or otherwise modified from time to time.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.
