(b) Loans and Borrowings. Each Revolving Loan shall be made as part of a Borrowing consisting of Revolving Loans made by the Lenders ratably in accordance with their Commitment Percentage. The failure of any Lender to make any Revolving Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Revolving Loans as required.

- 19 -

Date. Each such telephonic Borrowing request shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile to the Administrative Agent of a written notice (the “Notice of Borrowing”) in the form attached as Exhibit B approved by the Administrative Agent and signed by the Borrower. Each such telephonic request and written Notice of Borrowing shall specify the following information in compliance with this Section 2.01:

(1)

that a Revolving Loan is requested;

(2)

the requested Disbursement Date, which shall be a Business Day;

(3)

(ii) Minimum Amounts. Each Revolving Loan shall be in a minimum aggregate principal amount of $5,000,000, in the case of LIBOR Loans, or $1,000,000 (or the remaining Committed Amount, if less), in the case of Base Rate Loans, and integral multiples of $1,000,000 in excess thereof.

NY (ABA No. ▇▇▇▇▇▇▇▇▇ Ref: CEMEX) in New York City (the “Funding Account”) or any other account with such bank or any other financial institution designated by the Borrower in the applicable Notice of Borrowing. Unless the Administrative Agent shall have received notice from a Lender, prior to the time of any Borrowing, that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the

- 20 -

Administrative Agent may, but shall not be required to, assume that such Lender has made such share available on such date in accordance with Section 2.01(c) and may in its sole discretion, but shall not be required to, in reliance upon such assumption, make available to the Borrower a corresponding amount. If any Lender either does not make its share of the applicable Borrowing available to the Administrative Agent or delays in doing so past 4:00 p.m., New York City time, on the Disbursement Date (such Lender (until it makes such share available) hereinafter referred to as a “Defaulting Lender”), then the Administrative Agent shall immediately notify the Borrower of such default. If the Administrative Agent has, in its sole discretion, made available to the Borrower an amount corresponding to such Defaulting Lender’s share of the Borrowing, then the Defaulting Lender and the Borrower jointly and severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, on each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at:

(i)

If, with respect to the immediately preceding sentence, the Borrower pays such amount to the Administrative Agent, then the Defaulting Lender shall indemnify and hold harmless the Borrower from and against such amount, and if such Defaulting Lender pays such amount to the Administrative Agent, then such amount shall constitute such Defaulting Lender’s Loan included in such Borrowing. If the Administrative Agent, in its discretion, does not make available to the Borrower an amount corresponding to the Defaulting Lender’s share of the Borrowing then (x) the Defaulting Lender shall indemnify and hold harmless the Borrower from and against such amount as well as any and all losses, liabilities (including liabilities for penalties), actions, suits, judgments, demands, costs, and expenses (including reasonable fees and disbursements for counsel including allocated cost of internal counsel) resulting from any failure on the part of the Defaulting Lender to provide, or from any delay in providing, the Administrative Agent with such Defaulting Lender’s pro rata share of the Borrowing, but no Lender shall be so liable for any such failure on the part of or caused by any other Lender or the Administrative Agent or the Borrower, and (y) such share of the applicable Borrowing that was not made available shall (until made available) be disregarded for purposes of calculating the Commitment Fee pursuant to Section 4.03(a) and in the event such share has not been disregarded for such purposes, any amount paid by the Borrower in respect of such share shall be reimbursed to the Borrower by the applicable Defaulting Lender with interest thereon at the Federal Funds Rate for each day from and including the date such share of the Commitment Fee was paid by the Borrower to but excluding the date of reimbursement by the Defaulting Lender. The Administrative Agent, upon notice by the Borrower that such reimbursement is due from the applicable Defaulting Lender, shall notify such Defaulting Lender of the amount of the reimbursement due, including interest thereon, and shall forward such amount to the Borrower upon receipt from the Defaulting Lender. The Administrative Agent shall not, however, be liable to the Borrower for any failure by any Defaulting Lender to reimburse the Borrower for any amounts in respect of such Commitment Fee.

The Borrower shall have the option, on any Business Day, to extend existing Revolving Loans into a subsequent permissible Interest Period or to convert Revolving Loans into Revolving Loans of another interest rate type; provided, however, that (i) except as provided in Section 4.07, LIBOR Loans may be converted into Base Rate Loans only on the last day of the Interest Period applicable thereto unless the Borrower agrees to pay all Funding Losses, (ii) LIBOR Loans may be extended, and Base Rate Loans may be converted into LIBOR Loans, only if the conditions in Section 5.02 have been satisfied, (iii) Loans extended as, or converted into, LIBOR Loans shall be subject to the terms of the definition of “Interest Period” set forth in Section 1.01 and shall be in such minimum amounts as provided in Section 2.01(c)(ii), and (iv) any request for extension or conversion of a LIBOR Loan that shall fail to specify an Interest Period shall be deemed to be a request for an Interest Period of one month. Each such extension or conversion shall be effected by the Borrower by giving a written notice (or telephone notice promptly confirmed in writing) (a “Notice of Extension/Conversion”) to the Administrative Agent prior to 10:00 a.m., New York City time, on the LIBOR Business Day of, in the case of the conversion of a LIBOR Loan into a Base Rate Loan, and on the third LIBOR Business Day prior to, in the case of the extension of a LIBOR Loan as, or conversion of a Base Rate Loan into, a LIBOR Loan, the date of the proposed extension or conversion, substantially in the form of Exhibit C hereto, specifying (A) the date of the proposed extension or conversion, (B) the Loans to be so extended or converted, (C) the types of Revolving Loans into which such Loans are to be converted, and, if appropriate, (D) the applicable Interest Periods with respect thereto. Each Notice of Extension/Conversion shall be irrevocable and shall constitute a representation and warranty by the Borrower of the matters specified in Sections 5.02(a) through (e). So long as there is no Default or Event of Default, in the event the Borrower does not request extension or conversion of any LIBOR Loan in accordance with this Section, or any such conversion or extension is not required by this Section, then such LIBOR Loan shall be continued as a Base Rate Loan at the end of each Interest Period applicable thereto, until the Borrower selects an alternate Interest Period or converts such Loans to LIBOR Loans. It is hereby understood and agreed that such failure by the Borrower to request such extension or conversion resulting in the automatic conversion of a LIBOR Loan into a Base Rate Loan shall also constitute a representation and warranty by the Borrower of the matters specified in Sections 5.02(a) through (e). In the event any LIBOR Loans are not permitted to be converted into another LIBOR Loan hereunder, such LIBOR Loans shall automatically be converted to Base Rate Loans at the end of the applicable Interest Period with respect thereto. The Administrative Agent shall give each Lender notice as promptly as practicable of any such proposed extension or conversion affecting any Loan.

(f) Repayment. The principal amount of all Revolving Loans shall be due and payable in full on the Termination Date.

(g) Prepayment. Loans may be repaid in whole or in part without premium or penalty; provided that (i) Loans may be prepaid only upon five (5) Business Days’ prior written notice to the Administrative Agent, (ii) prepayments of LIBOR Loans must be accompanied by payment of any Funding Losses under Section 4.07, and (iii) partial prepayments shall be in minimum principal Dollar Amounts of $10,000,000.

- 22 -

(h) Revolving Notes. Each Lender’s Commitment Percentage of the Revolving Loans shall be evidenced by a duly executed revolving note in favor of such Lender in the form of Exhibit A attached hereto.

(i) Maximum Number of LIBOR Loans. The Borrower will be limited to a maximum number of ten (10) LIBOR Loans outstanding at any time. For purposes hereof, LIBOR Loans with separate or different Interest Periods will be considered as separate LIBOR Loans even if their Interest Periods expire on the same date.

(j) Notice. The Administrative Agent shall promptly advise each Lender of any change in Commitment Percentages made pursuant to Section 4.02.

2.02 Swing Line Loans.

(a) Swing Line Loans Commitments. During the Commitment Period, subject to the terms and conditions hereof, each Swing Line Lender hereby agrees to make Swing Line Loans to the Borrower in the aggregate amount up to but not exceeding the Swing Line Sublimit; provided, after giving effect to the making of any Swing Line Loan, in no event shall the aggregate amount of the Loans outstanding plus the aggregate amount of the Standby L/C Exposure exceed the Aggregate Committed Amount for the facility then in effect. Amounts borrowed pursuant to this Section 2.02 may be repaid, prepaid and reborrowed during the Commitment Period. Each Swing Line Lender’s commitment to make Swing Line Loans shall expire on the Termination Date and all Swing Line Loans and all other amounts owed hereunder with respect to the Swing Line Loans and the Revolving Commitments shall be paid in full no later than such date. Subject to Section 2.02(c)(iv), each Swing Line Loan shall mature on the Swing Line Maturity Date.

(b) Loans and Borrowings. Each Swing Line Loan shall be made as part of a Borrowing consisting of Swing Line Loans made by the Swing Line Lenders on a pro rata basis. The failure of any Swing Line Lender to make any Swing Line Loan required to be made by it shall not relieve any other Swing Line Lender of its obligations hereunder; provided that the Commitments of the Swing Line Lenders are several and no Swing Line Lender shall be responsible for any other Swing Line Lender’s failure to make Swing Line Loans as required.

(i) Swing Line Loans shall be made in an aggregate minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of that amount.

(ii) Whenever the Borrower desires that the Swing Line Lenders make a Swing Line Loan, the Borrower shall deliver to Administrative Agent, with a copy to each Swing Line Lender, a Swing Line Request no later than 11:00 a.m. (New York City time) on the proposed Disbursement Date. With respect to any Borrowing Date, the Borrower may deliver only a single Swing Line Request to the Administrative Agent. Any Swing Line Request, once delivered to the Administrative Agent in accordance with this Agreement, shall be irrevocable.

- 23 -

(iii) Each Swing Line Lender shall make its pro rata share of the amount of the requested Swing Line Loan available to the Administrative Agent by no later than 2:00 p.m. (New York City time) on the applicable Disbursement Date by wire transfer of same day funds in Dollars, at the account held by the Administrative Agent for such purpose most recently designated by it by notice to the Swing Line Lenders. Except as provided herein, upon satisfaction or waiver by the Swing Line Lenders of the conditions precedent specified herein, the Administrative Agent shall make the proceeds of such Swing Line Loans available to the Borrower on the applicable Disbursement Date by causing an amount of same day funds in Dollars equal to the proceeds of all such Swing Line Loans received by Administrative Agent from each Swing Line Lender to be credited to the account of the Borrower at the Administrative Agent’s Payment Office, or to such other account as may be designated in writing to Administrative Agent by the Borrower.

(iv) The Borrower shall have the option, on any Business Day, to extend an existing Swing Line Loan for a subsequent three Business Day period; provided, however, that in no event may a Swing Line Loan be extended for more that two consecutive three Business Day periods. Each such extension shall be effected by the Borrower by giving a written notice of such extension (or telephone notice promptly confirmed in writing) to the Administrative Agent prior to 10:00 a.m., New York City time, on the Business Day of such extension.

(d) Repayment and Participations.

(i) Swing Line Loans shall be repaid, together with all accrued and unpaid interest thereon on the earlier to occur of (i) the Swing Line Maturity date and (ii) the Commitment Termination Date.

(ii) With respect to any Swing Line Loans which have not been paid by the Borrower when due, each Swing Line Lender may at any time in its sole and absolute discretion, deliver to the Administrative Agent (with a copy to the Borrower), no later than 10:00 a.m. (New York City time) at least one (1) Business Day in advance of the proposed Disbursement Date, a notice (which shall be deemed to be a Notice of Borrowing given by the Borrower) requesting that the Lenders make Revolving Loans that are Base Rate Loans to the Borrower, or its designee, on such Disbursement Date in an amount equal to the aggregate amount of such Swing Line Loans (the “Refunded Swing Line Loans”) outstanding on the date a Swing Line Lender gives such Notice requesting that Lenders make Revolving Loans. For purposes of this Section 2.02, the Borrower agrees that such Base Rate Loan to be made by the Lenders pursuant to the Notice of Borrowing shall be made to the accounts of each of the Swing Line Lenders, as Borrower’s designee, on a pro rata basis. Anything contained in this Agreement to the contrary notwithstanding, (1) the proceeds of such Revolving Loans made by the Lenders other than the Lenders that are also Swing Line Lenders shall be immediately delivered by the Administrative Agent to each Swing Line Lender, as Borrower’s designee, on a pro rata basis and applied to repay a corresponding

- 24 -

portion of the Refunded Swing Line Loans and (2) on the day such Revolving Loans are made, each Swing Line Lender’s pro rata share of the Refunded Swing Line Loans shall be deemed to be paid by such Swing Line Lender with the proceeds of a Revolving Loan deemed to be made by such Swing Line Lender to the Borrower, or its designee, and such portion of the Swing Line Loans deemed to be so paid shall no longer be outstanding as Swing Line Loans and shall no longer be due, but shall instead constitute part of such Swing Line Lender’s outstanding Revolving Loans to the Borrower and shall be due under the revolving loan note, if any, issued by the Borrower to such Swing Line Lender in its capacity as Lender. The Borrower hereby authorizes the Administrative Agent and each Swing Line Lender to charge the Borrower’s accounts with the Administrative Agent and each Swing Line Lender (up to the amount available in each such account) in order to immediately pay each Swing Line Lender the amount of the Refunded Swing Line Loans to the extent the proceeds of such Revolving Loans made by the Lenders, including the Revolving Loan deemed to be made by such Swing Line Lender, are not sufficient to repay in full the Refunded Swing Line Loans. If any portion of any such amount paid (or deemed to be paid) to any Swing Line Lender should be recovered by or on behalf of the Borrower from such Swing Line Lender in bankruptcy, by assignment for the benefit of creditors or otherwise, the loss of the amount so recovered shall be ratably shared among all Lenders in the manner contemplated by Section 4.13.

(iii) If for any reason Revolving Loans are not made pursuant to Section 2.02(d)(ii) in an amount sufficient to repay any amounts owed to such Swing Line Lenders in respect of any outstanding Swing Line Loans on or before the third (3^rd) Business Day after demand is made for payment thereof by such Swing Line Lender, each Lender holding a Commitment shall be deemed to, and hereby agrees to, have purchased a participation in such outstanding Swing Line Loans, and in an amount equal to its pro rata share of the applicable unpaid amount together with accrued interest thereon. Upon one (1) Business Day’s notice from any Swing Line Lender, each Lender holding a Commitment shall deliver to each Swing Line Lender an amount equal to its respective participation in the applicable unpaid amount in same day funds at the domestic office of such Swing Line Lender. In order to evidence such participation, each Lender holding a Revolving Commitment agrees to enter into a participation agreement at the request of such Swing Line Lender in form and substance reasonably satisfactory to such Swing Line Lender. In the event any Lender holding a Revolving Commitment fails to make available to any Swing Line Lender the amount of such Lender’s participation as provided in this paragraph, each Swing Line Lender shall be entitled to recover such amount on demand from such Lender together with interest thereon for three Business Days at the rate customarily used by such Swing Line Lender for the correction of errors among banks and thereafter at the Base Rate, as applicable.

(iv) Notwithstanding anything contained herein to the contrary, (1) each Lender’s obligation to make Revolving Loans for the purpose of repaying any Refunded Swing Line Loans pursuant to the second preceding paragraph and

- 25 -

each Lender’s obligation to purchase a participation in any unpaid Swing Line Loans pursuant to the immediately preceding paragraph shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against any Swing Line Lender, any Credit Party or any other Person for any reason whatsoever; (B) the occurrence or continuation of a Default or Event of Default; (C) any adverse change in the business, operations, properties, assets, condition (financial or otherwise) or prospects of any Credit Party; (D) any breach of this Agreement or any other Credit Document by any party thereto; or (E) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing; provided, that such obligations of each Lender are subject to the condition that each Swing Line Lender believed in good faith that all conditions under Section 5.02 to the making of the applicable Refunded Swing Line Loans or other unpaid Swing Line Loans, were satisfied at the time such Refunded Swing Line Loans or unpaid Swing Line Loans were made, or the satisfaction of any such condition not satisfied had been waived by Requisite Lenders prior to or at the time such Refunded Swing Line Loans or other unpaid Swing Line Loans were made; and (2) no Swing Line Lender shall be obligated to make any Swing Line Loans (A) if it has elected not to do so after the occurrence and during the continuation of a Default or Event of Default or (B) at a time when a Funding Default exists unless such Swing Line Lender has entered into arrangements satisfactory to it and the Borrower to eliminate each such Swing Line Lender’s risk with respect to the Defaulting Lender’s participation in such Swing Ling Loan, including by cash collateralizing such Defaulting Lender’s pro rata share of the outstanding Swing Line Loans.

2.03 Interest.

(a) Base Rate Loans. Each Base Rate Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin.

(b) LIBOR Loans. Each LIBOR Loan shall bear interest at a rate per annum equal to LIBOR plus the Applicable Margin.

(c) Swing Line Loans. Each Swing Line Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin.

(d) Default Interest. Notwithstanding the foregoing, if any principal of, or interest on, any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration, by mandatory prepayment or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided above or (ii) in the case of any other amount, 2% plus the rate applicable to Base Rate Loans as provided in Section 2.03(a).

(e) Payment of Interest. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, upon termination of the

- 26 -

Commitments; provided that (i) interest accrued on a Swing Line Loan shall be payable on the Swing Line Maturity Date, (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any LIBOR Rate Borrowing prior to the end of the Interest Period therefore, accrued interest on such Borrowing shall be payable on the effective date of such conversion.

(f) Computation. All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Base Rate at times when the Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Base Rate or LIBOR Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

- 30 -

amount of such unreimbursed Drawing at the Federal Funds Rate from such Disbursement Date until the date payment is received by the Administrative Agent; provided, however, that if the Federal Funds Rate does not cover such Issuing Bank’s cost of funds, the applicable rate of interest shall be such rate as determined by such Issuing Bank, in good faith, to be equal to its cost of funds; and provided, further, that if any amount remains unpaid by any Lender for more than five Business Days after receipt of notice, such Lender shall, commencing on the day next following such fifth Business Day, pay interest to the Administrative Agent for the account of such Issuing Bank at a rate per annum equal to the Federal Funds Rate (or such other rate as may be determined by such Issuing Bank as set forth herein) plus 2.00%.

(g) The Borrower hereby confirms and acknowledges that each Lender shall have a direct claim against the Borrower for the principal of and interest on each portion of any unreimbursed Standby L/C Drawing advanced by such Lender to an Issuing Bank and that each Lender shall to the extent applicable be entitled to all the rights of the Issuing Bank against the Borrower (to the extent not exercised by such Issuing Bank) as if such Lender had funded its Commitment Percentage of the Standby L/C Drawing directly to the beneficiary of the applicable Standby L/C.

- 32 -

(h) Each Issuing Bank and each Lender, with respect to the amounts payable to it in respect of any unreimbursed Standby L/C Drawing, and the Administrative Agent, with respect to all amounts payable in respect of unreimbursed Standby L/C Drawings, shall maintain on its books in accordance with its usual practice, loan accounts, setting forth its Commitment Percentage of each Standby L/C Drawing, the applicable interest rate and the amounts of principal and interest paid and payable by the Borrower from time to time hereunder with respect thereto; provided, however, that the failure by an Issuing Bank, any Lender or the Administrative Agent to record any such amount on its books or any error in such recordation shall not affect the obligations of the Borrower with respect thereto. In the case of any dispute, action or proceeding relating to any amount payable in respect of any unreimbursed Standby L/C Drawings, the entries in each such account shall be prima facie evidence of such amount. In the case of any discrepancy between the entries in an Issuing Bank’s books and any Lender’s books or the Administrative Agent’s books, an Issuing Bank’s books shall be considered correct in the absence of manifest error.

3.05 Limited Liability of the Issuing Banks. As between an Issuing Bank on the one hand, and the Borrower on the other, the Borrower assumes all risks of any acts or omissions of the beneficiaries of Standby L/Cs with respect to their use of the Standby L/Cs or the proceeds thereof.

Upon at least five Business Days’ notice to the Administrative Agent, the Joint Bookrunners and the Issuing Banks, but no sooner than six months after the Effective Date, the Borrower may terminate the existing Commitments by instructing each beneficiary of a Standby L/C to surrender such Standby L/C to the relevant Issuing Bank for cancellation; and provided, further, however, that the existing Commitments shall not be terminated so long as (i) any Standby L/C is outstanding or (ii) any Loan is outstanding or (iii) any Drawing, interest, fee or expenses remain unpaid. Upon at least five Business Days prior notice to the Administrative Agent and the Issuing Banks, the Borrower may terminate any Standby L/C, in accordance with its terms, by surrendering, or causing the beneficiary thereof to surrender, such Standby L/C to the relevant Issuing Bank for cancellation.

- 33 -

(c) Reduction of Standby L/C. Upon at least five Business Days prior notice to the Administrative Agent and each Issuing Bank, the Borrower may reduce the stated amount of any Standby L/C to be reduced, in accordance with its terms, by surrendering, or causing the beneficiary thereof to surrender, such Standby L/C to the relevant Issuing Bank for cancellation in exchange for a new Standby L/C having the reduced stated amount and otherwise having the same terms as the Standby L/C being cancelled; provided, however, that the stated amount of any Standby L/C shall not as a result of such reduction be reduced below U.S.$3,000,000.

(d) Any reduction of the Commitments shall reduce the Commitment of each Lender pro rata except as otherwise specified in Section 4.02(e).

(e) No reduction or termination of the Commitments shall in any event release any Lender from any of its direct or indirect obligations to the Issuing Banks in respect of (i) any Standby L/Cs issued prior to such termination or reduction or (ii) any Drawing.

4.02 Extension of Termination Date.

(a) Extension of Termination Date/Reduction of Standby L/C. Upon at least five Business Days’ prior notice to the Administrative Agent and each Issuing Bank, but no sooner than six months after the Effective Date, the Borrower may permanently reduce the amount of the Aggregate Standby L/C Sublimit and the Standby L/C Sublimit for each Issuing Bank by a minimum amount of U.S.$5,000,000 or any integral multiple of U.S.$1,000,000 in excess thereof; provided, however, the Standby L/C Sublimit for any Issuing Bank may not be reduced below the Standby L/C Exposure of such Issuing Bank and any reductions in the Standby L/C Sublimit for the Issuing Banks must be made on a pro rata basis. The Borrower may, within 90 days, but not less than 45 days, prior to each anniversary date of the original Effective Date (each anniversary date being referred to as an “Anniversary Date”), by notice to the Administrative Agent, the Issuing Banks and the Lenders, make a written request of the Participating Lenders to extend the Termination Date for an additional period of one (1) year. The Administrative Agent will give prompt notice to each of the Participating Lenders of its receipt of any such request for extension of the Termination Date. Each Participating Lender shall make a determination not later than 30 days prior to the then applicable Anniversary Date (the “Extension Consent Date”) as to whether or not it will agree to extend the Termination Date as requested (such approval of an extension shall be an “Extension Consent”); provided, however, that failure by any Participating Lender to make a timely response to the Borrower’s request for extension of the Termination Date shall be deemed to constitute a refusal by such Participating Lender to an extension of the Termination Date.

(b) Lender Not Consenting. If by any Extension Consent Date the Borrower and the Administrative Agent have not received an Extension Consent from any Participating Lender, the Termination Date, as it relates to such Participating Lender, shall not be extended, the Commitment of such Participating Lender shall terminate on the Termination Date applicable to it and any Loans or Standby L/C, as applicable, made by such Participating Lender and all accrued and unpaid interest thereon shall be due and payable on such Termination Date. Upon the termination of the Commitment of any such

- 34 -

Lender, unless this Agreement is amended as provided in Sections 4.02(e) or 4.02(f), the aggregate amount of the Commitments shall be reduced by the amount of such terminated Commitment, and the Commitment Percentage of each other Lender shall be adjusted to that percentage obtained by dividing the Commitment of such Lender by the aggregate amount of the Commitments after giving effect to such reduction as provided in the definition of “Commitment Percentage”.

(c) Other Lenders. No refusal by any one Participating Lender to consent to any extension of the Termination Date shall affect the extension of the Termination Date as it may relate to the Commitment and Loans of any Participating Lender that consents to such extension as provided in Section 4.02(b), and one or more Participating Lenders may consent to the extension of the Termination Date as it relates to them notwithstanding any refusal by any other Lenders so to consent; provided that even as to the consenting Lenders, the Termination Date will be extended only upon consent to such an extension by the Required Lenders.

(d) Termination of Commitment. If any Participating Lender does not deliver an Extension Consent as provided in Section 4.02(b) and no Loans or Standby L/Cs, as applicable are then outstanding, the Borrower may upon at least three (3) Business Days’ prior notice to such Participating Lender and to the Administrative Agent terminate the Commitment of such Lender. Upon any such termination, the Commitment Percentage of each other Lender shall be adjusted, if necessary, to that percentage obtained by dividing the Commitment of such Lender by the aggregate amount of the Commitments after giving effect to such termination and any increases in the aggregate amount of the Commitments under the provisions of Section 4.02(e) or Section 4.02(f).

(e) Increase in Commitment of Other Lender or Lenders. If any Lender does not deliver an Extension Consent as provided in Section 4.02(b), upon the expiration of the Commitment of such Lender, or upon its termination as provided in Section 4.02(d), the Borrower may offer each Lender that has delivered an Extension Consent as provided in Section 4.02(b) a reasonable opportunity to increase its Commitment by an amount equal to its pro rata share (based on its Commitment before giving effect to such increase) of the Commitment of the Lender that does not deliver an Extension Consent as provided in Section 4.02(b). After giving such Lenders such an opportunity, the Borrower may with the approval of the Administrative Agent amend this Agreement to increase the Commitment of any other Lender or Lenders with the consent of such Lender or Lenders; provided that such increase does not increase the aggregate amount of the Commitments to an amount greater than the Aggregate Committed Amount in effect immediately before such expiration or termination.

(f) Additional Lender or Lenders. If any Lender does not deliver an Extension Consent as provided in Section 4.02(b), upon the expiration of the Commitment of such Lender, or upon its termination as provided in Section 4.02(d), the Borrower may with the approval of the Administrative Agent amend this Agreement as provided herein to add one or more other Lenders (each an “Additional Commitment Lender”) as parties, with such Commitments as may be agreed to by the Administrative Agent and such other Lender or Lenders; provided that such additions do not increase the Aggregate Committed Amount to an amount greater than the aggregate amount of Commitments in effect immediately before such expiration or termination.

- 35 -

4.03 Fees.

(a) Commitment Fee. The Borrower agrees to pay to the Administrative Agent, quarterly in arrears for each Utilization Period, for the account of the Lenders ratably in accordance with their Commitment Percentage a commitment fee (the “Commitment Fee”) (i) if the Utilization is greater than or equal to 50%, at the rate of 30% of the Applicable Margin per annum for the relevant Utilization Period on the average Available Commitments for the Utilization Period or (ii) if the Utilization is less than 50%, at the rate of 40% of the Applicable Margin per annum for the relevant Utilization Period on the average Available Commitments for the Utilization Period. The Commitment Fee shall accrue from the Effective Date to the Termination Date and shall be payable in arrears on the last day in each of March, June, September, and December and on the Termination Date provided that if any day or the Termination Date is not a Business Day, then the Commitment Fee shall be payable on the next succeeding Business Day.

(b) Standby L/C Fees. The Borrower will pay to each Issuing Bank Standby L/C documentation fees (the “Standby L/C Fees”) in the amounts and at the times agreed to by the Issuing Banks and the Borrower in the Original Fee Letter.

(c) Letter of Credit Utilization Fees. A letter of credit utilization fee, at a rate per annum equal to the Applicable Margin for the relevant quarterly period from time to time in effect, calculated on a per annum basis on the daily amount of Aggregate Standby L/C Exposure from time to time, payable to the Administrative Agent for the account of the Lenders in arrears on (i) the last day of each calendar quarter, commencing on the first such date after the Borrowing Date, and (ii) the Termination Date.

(d) Joint Bookrunners Fees. The Borrower will pay to the Joint Bookrunners, for the sole account of the Joint Bookrunners, the arrangement fees (the “Joint Bookrunners Fees”) and other fees in the amounts and at the times agreed to by the Joint Bookrunners and the Borrower in the New Fee Letter.

(e) Amendment Fee. The Borrower will pay to the Administrative Agent, for the account of the Lenders, an amendment fee (the “Amendment Fee”) in accordance with the Summary of Terms and Conditions agreed to by the Borrower and the Joint Bookrunners on April 20, 2005.

4.04 Computation of Fees. All fees calculated on a per annum basis shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed.

4.05 Taxes.

(a) Any and all payments by the Borrower or a Guarantor, as the case may be, to any Lender, any Issuing Bank, the Joint Bookrunners or the Administrative Agent under this Agreement and the other Transaction Documents shall be made free and clear of, and without deduction or withholding for or on account of, any Taxes. In addition, the Borrower shall promptly pay all Other Taxes.

- 36 -

(b) Except as otherwise provided in Section 4.05(c), the Borrower and the Guarantors jointly and severally agree to indemnify and hold harmless each Lender, each Issuing Bank and the Administrative Agent for the full amount of Taxes or Other Taxes (without duplication) excluding in each case United States backup withholding Taxes imposed because of payee underreporting (including any Taxes or Other Taxes (without duplication) imposed by any jurisdiction on amounts payable under this Section 4.05) paid by or assessed against any Lender, any Issuing Bank or the Administrative Agent in respect of any sum payable hereunder and any liability (including penalties, interest, additions to tax and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted, except to the extent that such penalties, interest, additions to tax or expenses are incurred solely as a result of any gross negligence or willful misconduct of such Lender, Issuing Bank or Administrative Agent, as the case may be. Payment under this indemnification shall be made within 30 days after the date any Lender, any Issuing Bank or the Administrative Agent makes written demand therefor, setting forth in reasonable detail the basis and calculation of such amounts (such written demand shall be presumed correct, absent significant error).

(c) If the Borrower or the Guarantors, as the case may be, shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any sum payable hereunder to any Lender, any Issuing Bank or the Administrative Agent, then:

(i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section 4.05, but excluding in each case United States backup withholding Taxes imposed because of payee underreporting) such Lender, such Issuing Bank or the Administrative Agent receives an amount equal to the sum it would have received had no such deductions or withholdings been made; provided, that, the Borrower shall not be required to increase any amounts payable to such Lender, Issuing Bank or the Administrative Agent to the extent such increased amounts would be in excess of the amounts that would have been payable to such Lender or Issuing Bank had such Lender, Issuing Bank or Administrative Agent complied with the requirements of Section 4.05(f) or to the extent provided in Section 4.05(g);

(ii) the Borrower or the Guarantors, as the case may be, shall make such deductions and withholdings; and

(iii) the Borrower or the Guarantors, as the case may be, shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with applicable law.

(d) Within 30 days after the date of any payment by the Borrower or the Guarantors, as the case may be, of Taxes or Other Taxes, the Borrower or the Guarantors, as the case may be, shall furnish to the Administrative Agent the original or a certified copy of a receipt evidencing payment thereof or other evidence of payment reasonably satisfactory to the Administrative Agent.

- 37 -

(e) If the Borrower or the Guarantors, as the case may be, is required to pay additional amounts to the Administrative Agent, any Lender or any Issuing Bank pursuant to Section 4.05(c) other than amounts related to the withholding of Mexican tax at the rate applicable to interest payments received by foreign financial institutions registered with the Secretaría de Hacienda y Crédito Público as a Foreign Financial Institution for the purposes of Article 195, Section I of the Mexican Income Tax law, then the Administrative Agent, such Lender or such Issuing Bank, as the case may be, shall, upon reasonable request by the Borrower or the Guarantors, use reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction of its Lending Office, issuing office or office for receipt of payments by the Borrower and Guarantors hereunder, as the case may be, so as to eliminate or reduce the obligation of the Borrower or the Guarantor, as the case may be, to pay any such additional amounts which may thereafter accrue or to indemnify the Administrative Agent, such Lender or such Issuing Bank in the future, if such change in the reasonable judgment of the Administrative Agent, such Lender or such Issuing Bank is not otherwise disadvantageous to such Lender or such Issuing Bank.

(f) Each Issuing Bank, each Lender and the Administrative Agent shall, from time to time at the request of the Borrower or the Administrative Agent (as the case may be), promptly furnish to the Borrower and the Administrative Agent (as the case may be), such forms, documents or other information (which shall be accurate and complete) as may be reasonably required to establish any available exemption from, or reduction in the amount of, applicable Taxes; provided, however, that none of any Issuing Bank, any Lender or the Administrative Agent shall be obliged to disclose information regarding its tax affairs or computations to the Borrower in connection with this paragraph (f), it being understood that the identity of any Person shall not be considered for these purposes as information regarding its tax affairs or computations. Each of the Borrower and the Administrative Agent shall be entitled to rely on the accuracy of any such forms, documents or other information furnished to it by any Person and shall have no obligation to make any additional payment or indemnify any Person for any Taxes, interest or penalties that would not have became payable by such Person had such documentation been accurate.

(g) In the case of an assignment, transfer, grant of a participation, designation of a new Lending Office, issuing office [or Administrative Agent’s Payment Office or appointment of a successor Administrative Agent], the Borrower and Guarantors shall not be required to pay or increase any amounts, pursuant to this Section 4.05 following such event, in excess of the amounts the Borrower and Guarantors were required to pay or increase immediately prior to such an event, except to the extent such event occurs pursuant to Section 4.12 or to the extent of increases in such amounts resulting from a change in applicable law occurring after such event.

(h) If any Issuing Bank, the Administrative Agent or any Lender receives a refund or credit in respect of Taxes or Other Taxes as to which it has been indemnified by

- 38 -

the Borrower or a Guarantor, as the case may be, pursuant to Section 4.05(b) and such refund or credit is directly and clearly attributable to this Agreement, it shall notify the Borrower or such Guarantor, as the case may be, of the amount of such refund or credit and shall return to the Borrower or such Guarantor, as the case may be, such refund or the benefit of such credit; provided, however, that (A) such Issuing Bank, the Administrative Agent or such Lender, as the case may be, shall not be obligated to make any effort to obtain such refund or credit or to provide the Borrower or the Guarantors with any information on or justification for the arrangement of its tax affairs or otherwise disclose to the Borrower, the Guarantors or any other Person any information that it considers to be proprietary or confidential, and (B) the Borrower or such Guarantor, as the case may be, upon the request of such Issuing Bank, the Administrative Agent or such Lender, as the case may be, shall return the amount of such refund or the benefit of such credit to such Issuing Bank, the Administrative Agent or such Lender, as the case may be, if such Issuing Bank, the Administrative Agent or such Lender, as the case may be, is required to repay the amount of such refund or the benefit of such credit to the relevant authorities within six years of the date the Borrower or such Guarantor, as the case may be, is paid such amount by such Issuing Bank, the Administrative Agent or such Lender, as the case may be.

(i) The agreements in this Section 4.05 shall survive the termination of this Agreement and the payment of the Borrower’s Obligations.

4.06 General Provisions as to Payments.

(a) All payments to be made by the Borrower or the Guarantors, as the case may be, shall be made without set-off, counterclaim or other defense. Except as otherwise expressly provided herein, all payments by the Borrower shall be made to the Administrative Agent for the account of the Lenders, the Swing Line Lenders or the Issuing Banks, as the case may be, at the Administrative Agent’s Payment Office, and shall be made in Dollars and in immediately available funds, no later than 3:30 p.m. (New York City time) (but not earlier than 11:30 a.m. (New York City time) in respect of any Drawing under a Standby L/C), on the dates specified herein but in no event prior to the payment by the relevant Issuing Bank of such Drawing, as the case may be, to be reimbursed. The Administrative Agent will promptly distribute to the relevant Issuing Bank or to each Lender its Commitment Percentage (or other applicable share as expressly provided herein) of each payment in like funds as received. Any payment received by the Administrative Agent later than 3:30 p.m. (New York City time) shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue until such following Business Day.

(b) Except and to the extent otherwise specifically provided herein, whenever any payment to be made hereunder is due on a day which is not a Business Day, the date for payment thereof shall be extended to the immediately following Business Day and, if interest is stated to be payable in respect thereof, interest shall continue to accrue to such immediately following Business Day.

- 39 -

(c) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to an Issuing Bank or the Lenders 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 (but shall not be so required), in reliance upon such assumption, cause to be distributed to the relevant Issuing Bank or each Lender, as the case may be, on such due date an amount equal to the amount then due to such Issuing Bank or such Lender. If and to the extent that the Borrower shall not have made such payment, the relevant Issuing Bank or each Lender, as the case may be, shall repay to the Administrative Agent forthwith on demand such amount distributed to such Issuing Bank or such Lender together with accrued interest thereon, for each day from the date such amount is distributed to such Issuing Bank or such Lender until the date such Issuing Bank or such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate; provided, however, that if any amount remains unpaid by the relevant Issuing Bank or any Lender for more than five Business Days after the Administrative Agent has made a demand for such amount, such Issuing Bank or such Lender shall, commencing on the day next following such fifth Business Day, pay interest to the Administrative Agent at a rate per annum equal to the Federal Funds Rate plus 1%, and, provided further, that if any such amount remains unpaid by the relevant Issuing Bank or any Lender for more than ten Business Days, such Issuing Bank or such Lender shall, commencing on the day next following such tenth Business Day, pay interest to the Administrative Agent at a rate per annum equal to the Federal Funds Rate plus 2.00%.

4.07 Funding Losses. If the Borrower makes any payment of principal with respect to any LIBOR Loan on any day other than the last day of the Interest Period applicable thereto, or if the Borrower fails to borrow any LIBOR Loans after notice has been given to any Lender in accordance with Section 2.01 or to convert or continue a Loan as a LIBOR Loan after a Notice of Extension/Conversion has been delivered by the Borrower pursuant to Section 2.01(e), or if the Borrower fails to prepay any LIBOR Loans after notice has been given pursuant to Section 2.01, the Borrower shall reimburse each Lender within 15 days after demand for any resulting loss or expense incurred by it, including any loss incurred in obtaining, liquidating or reemploying deposits bearing interest by reference to LIBOR from third parties (“Funding Losses”), provided such Lender shall have delivered to the Borrower a certificate setting forth in reasonable detail the computations for the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error.

4.08 Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any LIBOR Loan:

(a) the Administrative Agent determines that by reason of circumstances affecting the London interbank market, reasonably adequate means do not exist for ascertaining LIBOR applicable to such Interest Period or that deposits in Dollars (in the applicable amounts) are not being offered in the London interbank market for such Interest Period, or

- 40 -

(b) the Required Lenders advise the Administrative Agent that LIBOR as determined by the Administrative Agent will not adequately and fairly reflect the cost to any Lender of making or maintaining its Loan for such Interest Period,

(c) then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders. In the event of any such determination or advice, until the Administrative Agent shall have notified the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, any request by the Borrower for a Loan of the affected amount or Interest Period, or a conversion to or continuation of a Loan of the affected amount or Interest Period shall be deemed rescinded and such request shall instead be considered a request for a Base Rate Loan. Each determination by the Administrative Agent hereunder shall be conclusive absent manifest error.

4.09 Capital Adequacy.

If any Participating Lender has determined, after the date hereof, that the adoption or the becoming effective of, or any change in, or any change by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof in the interpretation or administration of, any applicable law, rule, or regulation regarding capital adequacy, or compliance by such Participating Lender with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, has or would have the effect of increasing such Participating Lender’s cost of maintaining its Commitment or Standby L/C, as the case may be, or making or maintaining any Loans or any Standby L/C, as the case may be, or reducing the rate of return on such Participating Lender’s capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Participating Lender could have achieved but for such adoption, effectiveness, change, or compliance (taking into consideration such Lender’s policies with respect to capital adequacy), then, upon notice from such Participating Lender to the Borrower, the Borrower shall be obligated to pay to such Participating Lender such additional amount or amounts as will compensate such Participating Lender for such increased cost or reduction in amount received. Each determination by any such Lender of amounts owing under this Section shall, absent manifest error, be conclusive and binding on the parties hereto. The relevant Lender will, upon request, provide a certificate in reasonable detail as to the amount of such increased cost or reduction in amount received and method of calculation.

Upon any Participating Lender’s making a claim for compensation under this Section 4.09, (i) such Participating Lender shall use commercially reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction of its lending office or assign its rights and obligations hereunder to another of its offices, branches or affiliates so as to eliminate or reduce any such additional payment by the Borrower which may thereafter accrue, if such change is not otherwise disadvantageous to such Lender, and (ii) the Borrower may replace such Lender in accordance with Section 4.12.

4.10 Illegality.

(a) Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof occurring

- 41 -

after the Effective Date shall make it unlawful for any Lender to make or maintain any Commitment or any Loan as contemplated by this Credit Agreement, then such Lender, together with Lenders giving notice under Section 4.08, shall be an “Affected Lender” and by written notice to the Borrower and to the Administrative Agent:

(i) such Lender may declare that such Loans will not thereafter (for the duration of such unlawfulness or impossibility) be made by such Lender hereunder, whereupon, in the case of any request for a LIBOR Loan, as to such Lender, such request shall only be deemed a request for a Base Rate Loan (unless it should also be illegal for the Affected Lender to provide a Base Rate Loan, in which case such Loan shall bear interest at a commensurate rate to be agreed upon by the Administrative Agent and the Affected Lender, and so long as no Event of Default shall have occurred and be continuing, the Borrower), unless such declaration shall be subsequently withdrawn;

(ii) such Lender may require that all outstanding LIBOR Loans, made by it be converted to Base Rate Loans, in which event all such LIBOR Loans shall be automatically converted to Base Rate Loans as of the effective date of such notice as provided in paragraph (b) below; and

(iii) if it is also illegal for the Affected Lender to make Base Rate Loans, such Lender may declare all amounts owed to them by the Borrower to the extent of such illegality to be due and payable; provided, however, the Borrower has the right, with the consent of the Administrative Agent to find an additional Lender to purchase the Affected Lenders’ rights and obligations.

In the event any Lender shall exercise its rights under (i) or (ii) above with respect to any Loans, all payments and prepayments of principal that would otherwise have been applied to repay the LIBOR Loans that would have been made by such Lender or the converted LIBOR Loans of such Lender shall instead be applied to repay the Base Rate Loans made by such Lender in lieu of, or resulting from the conversion, of such LIBOR Loans.

(b) For purposes of this Section 4.10, a notice to the Borrower by any Lender shall be effective as to each such Loan, if lawful, on the last day of the Interest Period currently applicable to such Loan; in all other cases such notice shall be effective on the date of receipt by the Borrower.

4.11 Requirements of Law.

If, after the date hereof, the adoption of or any change in any Requirement of Law or in the interpretation or application thereof applicable to any Lender, or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority, in each case made subsequent to the Effective Date (or, if later, the date on which such Lender becomes a Lender):

(a) shall impose, modify, or hold applicable any reserve, special deposit, compulsory loan, or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans, or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the LIBOR hereunder; or

- 42 -

(b) shall impose on such Lender any other condition (excluding any tax of any kind whatsoever);

and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender reasonably deems to be material, of making, converting into, continuing, or maintaining LIBOR Loans or to reduce any amount receivable hereunder in respect thereof, then, in any such case, upon notice delivered to the Borrower from such Lender, through the Administrative Agent, in accordance herewith, the Borrower shall be obligated to promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable; provided that, in any such case, the Borrower may elect to convert the LIBOR Loans made by such Lender hereunder to Base Rate Loans by giving the Administrative Agent at least one (1) Business Day’s notice of such election. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall provide notice thereof to the Borrower, promptly upon occurrence of such event, but in any case within three (3) days from the date of such event, through the Administrative Agent, certifying (x) that one of the events described in this paragraph (a) has occurred and describing in reasonable detail the nature of such event, (y) as to the increased cost or reduced amount resulting from such event and (z) as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof. Such a certificate as to any additional amounts payable pursuant to this subsection submitted by such Lender, through the Administrative Agent, to the Borrower shall be conclusive and binding on the parties hereto in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. If any Lender becomes aware of a proposed change in any Requirement of Law that would entitle it to claim any additional amounts pursuant to this Section it shall promptly, upon the Lender becoming aware of such event, provide notice to the Borrower through the Administrative Agent.

4.12 Substitute Lenders. If any Lender has demanded compensation pursuant to Sections 4.09 or 4.11 or has exercised its rights pursuant to Section 4.10(a)(iii), and such Lender does not waive its right to future additional compensation pursuant to Section 4.09 or 4.11, the Borrower shall have the right (i) to replace such Lender with a Substitute Lender or Substitute Lenders that shall succeed to the rights of such Lender under this Agreement upon execution of an Assignment and Assumption Agreement and payment by the Borrower of the related processing fee of U.S.$3,500 to the Administrative Agent and a fee of U.S.$1,500 payable directly to each Issuing Bank; or (ii) to remove such Lender, reduce the Commitments by the amount of the Commitment of such Lender, and adjust the Commitment Percentage of each Lender such that the percentage of each other Lender shall be increased to equal the percentage equivalent of a fraction. The numerator of which is the Commitment of such other Lender and the denominator of which is the Commitments of the Lenders minus the Commitments of the Lender who demanded payment pursuant to Sections 4.09 or 4.11 or exercised its rights pursuant to Section 4.10(a)(iii); provided, however, that such Lender shall not be replaced or removed hereunder until such Lender has been repaid in full all amounts owed to it pursuant to this Agreement and the other Transaction Documents (including Sections 4.07 and 4.09) unless any such amount is being contested by the Borrower in good faith.

- 43 -

4.13 Sharing of Payments, Etc.

(a) If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Obligations owing to it any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its Commitment Percentage of payments on account of the Obligations obtained by all the Participating Lenders (an “excess payment”), such Lender shall forthwith (i) notify the Administrative Agent of such fact, and (ii) purchase from the other Lenders such participations in such Obligations owing to them 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 the purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s Commitment Percentage (according to the proportion of (A) the amount of such paying Lender’s required repayment to (B) 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. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of demonstrable error) of participations purchased pursuant to this Section 4.13 and will in each case notify the Lenders following any such purchases.

(b) If any Lender shall commence any action or proceeding in any court to enforce its rights hereunder after consultation with the other Lenders and, as a result thereof or in connection therewith, it shall receive any excess payment, then such Lender shall not be required to share any portion of such excess payment with any Lender which has the legal right to, but does not, join in any such action or proceeding or commence and diligently prosecute a separate action or proceeding to enforce its rights in another court.

(c) The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 4.13 may exercise all its rights of set-off with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

8.07 Books and Records. The Borrower will keep, and cause each of its Subsidiaries to keep, proper books of record and account, in which full and correct entries shall be made of all financial transactions and the assets and business of the Borrower and each such Subsidiary in accordance with Mexican GAAP, consistently applied.

The Borrower will conduct, and cause each of its Subsidiaries to conduct, all transactions otherwise permitted under this Agreement with any of its Affiliates on terms that are commercially reasonable and no less favorable to the Borrower or such Subsidiary than it would obtain in a comparable arm’s-length transaction with a Person not an Affiliate.

ARTICLE X

OBLIGATIONS OF GUARANTORS

10.01 The Guaranty. Each of the Guarantors jointly and severally hereby unconditionally and irrevocably guarantee (as a primary obligor and not merely as surety) payment in full as provided herein of all Obligations payable by the Borrower to each Participating Lender, the Administrative Agent and the Joint Bookrunners under this Agreement and the other Transaction Documents and the Fee Letters, as and when such amounts become payable (whether at stated maturity, by acceleration or otherwise).

10.02 Nature of Liability. The obligations of the Guarantors hereunder are guarantees of payment and shall remain in full force and effect until all Obligations of the Borrower have been validly, finally and irrevocably paid in full and all Commitments have been terminated, and shall not be affected in any way by the absence of any action to obtain such amounts from the Borrower or by any variation, extension, waiver, compromise or release of any or all Obligations from time to time therefor. Each Guarantor waives all requirements as to promptness, diligence, presentment, demand for payment, protest and notice of any kind with respect to this Agreement and the other Transaction Documents.

- 62 -

10.03 Unconditional Obligations. Notwithstanding any contrary principles under the laws of any jurisdiction other than the State of New York, the obligations of each of the Guarantors hereunder shall be unconditional, irrevocable and absolute and, without limiting the generality of the foregoing, shall not be impaired, terminated, released, discharged or otherwise affected by the following:

(a) the existence of any claim, set-off or other right which either of the Guarantors may have at any time against the Borrower, the Administrative Agent, the Issuing Banks, any Lenders or any other Person, whether in connection with this transaction or with any unrelated transaction;

(b) any invalidity or unenforceability of this Agreement or any other Transaction Document relating to or against the Borrower or either of the Guarantors for any reason (including for the reason that the obtaining of the Standby L/Cs may be in excess of the powers of the Borrower or of its officers, directors or other agents, acting or purporting to act on its behalf, or be in any way irregular or defective);

(c) any provision of applicable law or regulation purporting to prohibit the payment by the Borrower of any amount payable by the Borrower under this Agreement or any of the other Transaction Documents or the payment, observance, fulfillment or performance of any other Obligations;

(d) any change in the name, purposes, business, capital stock (including the ownership thereof) or constitution of the Borrower;

(e) any amendment, waiver or modification of any Transaction Document in accordance with the terms hereof and thereof; or

10.04 Independent Obligation. The obligations of each of the Guarantors hereunder are independent of the Borrower’s obligations under the Transaction Documents and of any guaranty or security that may be obtained for the Obligations. The Administrative Agent and the Participating Lenders may neglect or forbear to enforce payment hereunder, under any Transaction Document or under any guaranty or security, without in any way affecting or impairing the liability of each Guarantor hereunder. The Administrative Agent or the Participating Lenders shall not be obligated to exhaust recourse or take any other action against the Borrower or under any agreement to purchase or security which the Administrative Agent or the Participating Lenders may hold before being entitled to payment from the Guarantors of the obligations hereunder or proceed against or have resort to any balance of any deposit account or credit on the books of the Administrative Agent or the Participating Lenders in favor of the Borrower or each of the Guarantors.

Each of the Guarantors hereby waives notice of acceptance of this ARTICLE X and notice of any liability to which it may apply, and waives presentment, demand for payment, protest, notice of dishonor or nonpayment of any such liability, suit or the taking of other action by the Administrative Agent or the Participating Lenders against, and any other notice, to the Guarantors.

10.06 Waiver of Defenses. To the extent permitted by New York law and notwithstanding any contrary principles under the laws of any other jurisdiction, each of the Guarantors hereby waives any and all defenses to which it may be entitled, whether at common law, in equity or by statute which limits the liability of, or exonerates, guarantors or which may conflict with the terms of this ARTICLE X, including failure of consideration, breach of warranty, statute of frauds, merger or consolidation of the Borrower, statute of limitations, accord and satisfaction and usury. Without limiting the generality of the foregoing, each of the Guarantors consents that, without notice to such Guarantor and without the necessity for any additional endorsement or consent by such Guarantor, and without impairing or affecting in any way the liability of such Guarantor hereunder, the Administrative Agent and the Participating Lenders may at any time and from time to time, upon or without any terms or conditions and in whole or in part, (a) change the manner, place or terms of payment of, and/or change or extend the time or payment of, renew or alter, any of the Obligations, any security therefor, or any liability incurred directly or indirectly in respect thereof, and this ARTICLE X shall apply to the Obligations as so changed, extended, renewed or altered; (b) exercise or refrain from exercising any right against the Borrower or others (including the Guarantors) or otherwise act or refrain from acting, (c) settle or compromise any of the Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any such liability (whether due or not) of the Borrower to creditors of the Borrower other than the Administrative Agent and the Participating Lenders and the Guarantors, (d) apply any sums by whomsoever paid or howsoever realized, other than payments of the Guarantors of the Obligations, to any liability or liabilities of the Borrower under the Transaction Documents or any instruments or agreements referred to herein or therein, to the Administrative Agent and the Participating Lenders regardless of which of such liability or liabilities of the Borrower under the Transaction Documents or any instruments or agreements referred to herein or therein remain unpaid; (e) consent to or waive any breach of, or any act, omission or default under the Obligations or any of the instruments or agreements referred to in this Agreement and the other Transaction Documents, or otherwise amend, modify or supplement the Obligations or any of such instruments or agreements, including the Transaction Documents; and/or (f) request or accept other support of the Obligations or take and hold any security for the payment of the Obligations or the obligations of the Guarantors under this ARTICLE XI, or allow the release, impairment, surrender, exchange, substitution, compromise, settlement, rescission or subordination thereof. Furthermore, each of the Guarantors hereby waives to the extent permitted by law any right to which it may be entitled to under Articles 2830, 2836, 2842, 2845, 2846, 2848 and 2849 of the Mexican Federal Civil Code and related Articles contained in the Civil Codes of the States in Mexico. The Guarantors further expressly waive the benefits of order, excusión y division contained in Articles 2814, 2815, 2817, 2818, 2820, 2821, 2822, 2823, 2837, 2838, 2840, 2841

and other related Articles of the Mexican Federal Civil Code and related Articles contained in other Civil Codes of the States of Mexico. The Guarantors hereby represent that the terms of each such provision of each such civil code are known in form and substance to each such Guarantor.

10.07 Bankruptcy and Related Matters.

(a) So long as any of the Obligations remain outstanding, each of the Guarantors shall not, without the prior written consent of the Administrative Agent (acting with the consent of the Required Lenders), commence or join with any other Person in commencing any bankruptcy, liquidation, reorganization, concurso mercantil or insolvency proceedings of, or against, the Borrower.

(b) If acceleration of the time for payment of any amount payable by the Borrower under this Agreement or the Notes is stayed upon the insolvency, bankruptcy, reorganization, concurso mercantil or any similar event of the Borrower or otherwise, all such amounts otherwise subject to acceleration under the terms of this Agreement shall nonetheless be payable by the Guarantors hereunder forthwith on demand by the Administrative Agent made at the request of the Participating Lenders.

(c) The obligations of each of the Guarantors under this ARTICLE X shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any proceeding or action, voluntary or involuntary, involving the bankruptcy, insolvency, concurso mercantil, receivership, reorganization, marshalling of assets, assignment for the benefit of creditors, readjustment, liquidation or arrangement of the Borrower or similar proceedings or actions or by any defense which the Borrower may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding or action. Without limiting the generality of the foregoing, the Guarantors’ liability shall extend to all amounts and obligations that constitute the Obligations and would be owed by the Borrower but for the fact that they are unenforceable or not allowable due to the existence of any such proceeding or action.

(d) Each of the Guarantors acknowledges and agrees that any interest on any portion of the Obligations which accrues after the commencement of any proceeding or action referred to above in Section 10.07(c) (or, if interest on any portion of the Obligations ceases to accrue by operation of law by reason of the commencement of said proceeding or action, such interest as would have accrued on such portion of the Obligations if said proceedings or actions had not been commenced) shall be included in the Obligations, it being the intention of the Guarantors, the Administrative Agent, and the Participating Lenders that the Obligations which are to be purchased by the Guarantors pursuant to this ARTICLE X shall be determined without regard to any rule of law or order which may relieve the Borrower of any portion of such Obligations. The Guarantors will take no action to prevent any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar person from paying the Administrative Agent, or allowing the claim of the Administrative Agent, for the benefit of the Administrative Agent, and the Participating Lenders, in respect of any such interest accruing after the date of which such proceeding is commenced, except to the extent any such interest shall already have been paid by the Guarantors.

- 65 -

(e) Notwithstanding anything to the contrary contained herein, if all or any portion of the Obligations are paid by or on behalf of the Borrower, the obligations of the Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered, directly or indirectly, from the Administrative Agent and/or the Participating Lenders as a preference, preferential transfer, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Obligations for all purposes under this ARTICLE X, to the extent permitted by applicable law.

10.08 No Subrogation. Notwithstanding any payment or payments made by any of the Guarantors hereunder or any set-off or application of funds of any of the Guarantors by the Administrative Agent or any Participating Lender, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any Participating Lender against the Borrower or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any Participating Lender for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Administrative Agent and the Participating Lenders by the Borrower on account of the Obligations shall have been indefeasibly paid in full in cash. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been indefeasibly paid in full in cash, such amount shall be held by such Guarantor in trust for the Issuing Bank, the Administrative Agent and the Lenders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine.

10.09 Right of Contribution. Subject to Section 10.08, each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. The provisions of this Section 10.09 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent, the Joint Bookrunners and the Participating Lenders, and each Guarantor shall remain liable to the Administrative Agent, the Joint Bookrunners and the Participating Lenders for the full amount guaranteed by such Guarantor hereunder.

10.10 General Limitation on Guaranty. In any action or proceeding involving any applicable corporate law, or any applicable bankruptcy, insolvency, reorganization, concurso mercantil or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Section 10.10 would otherwise, taking into account the provisions of Section 10.09, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 10.01, then,

- 66 -

notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Guarantor, any Participating Lender, the Administrative Agent or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

10.11 Covenants of the Guarantors. Each Guarantor hereby covenants and agrees that, so long as any Obligations under this Agreement and any other Transaction Document remains unpaid, any Standby L/C remains outstanding or any Participating Lender has any Commitment hereunder, it shall comply with the covenants contained or incorporated by reference in this Agreement to the extent applicable to it as a Subsidiary of the Borrower.

- 69 -

(iii) demand that the Borrower promptly and in any event no later than the next Business Day deliver cash to the Administrative Agent for the benefit of Issuing Banks (and Borrower shall then promptly and in any event no later than the next Business Day after receipt of such demand so deliver) in an amount equal to 100% of the aggregate outstanding amount of Standby L/Cs;

If no successor agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Participating Lenders and the Borrower, a successor agent from among the Participating Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor agent effective upon its appointment, and the retiring Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act on the part of such retiring Administrative Agent. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this ARTICLE XII and Sections 15.04 and 15.05 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.

The rights and remedies herein provided are cumulative and not exclusive of any rights or remedies provided by law.

The Borrower agrees to indemnify and hold harmless the Joint Bookrunners, the Administrative Agent, each Issuing Bank and each Lender and each of their Affiliates and their officers, directors, employees, agents and advisors (each, an “Indemnified Party”) from and against any and all claims, damages, losses, liabilities and expenses (including reasonable fees and expenses of counsel and the allocated cost of in-house counsel), but excluding taxes that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (a) the Transaction Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Loans or (b) or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 15.05 applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, its directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. The Borrower and each Guarantor also agrees not to assert any claim against the Joint Bookrunners, the Administrative Agent, an Issuing Bank, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Transaction Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Transaction Documents. Neither the Joint Bookrunner, the Administrative Agent, an Issuing Bank nor any Lender shall be deemed to have any fiduciary relationship with the Borrower or any Guarantor.

15.06 Successor and Assigns.

(a) The provisions of this Agreement shall be binding upon the Borrower, the Guarantors, their successors and assigns and shall inure to the benefit of the Issuing Bank, the Joint Bookrunners, the Administrative Agent and the Lenders and their respective successors and assigns, except that the Borrower and the Guarantors may not assign or otherwise transfer any of their rights or obligations under this Agreement without the prior written consent of all Lenders except pursuant to the terms of this Agreement.

(b) Any Lender (other than an Issuing Bank in its capacity as such) may at any time, and any Lender, if demanded by the Borrower or an Issuing Bank pursuant to Section 2.01(d) or Section 4.10 upon at least five Business Days’ notice to such Lender and the Administrative Agent, shall, assign to one or more commercial banks either (i) registered as a Foreign Financial Institution and a resident (or having its principal office as a resident, if lending through a branch or agency) for tax purposes in a jurisdiction that is a party to an income tax treaty to avoid double taxation with Mexico on the date of such assignment, qualified to receive the benefits of said treaty or (ii) organized and existing under the laws of Mexico on the date of such assignment (each an “Assignee”) all, or a proportionate part of all, of its Commitment and its rights and obligations under this Agreement and the Notes, and such Assignee shall assume such

- 81 -

rights and obligations, pursuant to an Assignment and Assumption Agreement executed by such Assignee and such transferor Lender, with (and subject to) the subscribed consent of the Borrower and the Administrative Agent (which consents shall not be unreasonably withheld or delayed, and if a Default or Event of Default has occurred and is continuing, the consent of the Borrower shall not be required) and the Issuing Bank (which consent may be withheld for any reason; except that where such Assignee is an OECD Bank, consent may not be unreasonably withheld); provided, however, that if an Assignee is an Affiliate of such transferor Lender, which Affiliate is registered as a Foreign Financial Institution and meets the tax residence and qualification requirements of clause (ii) above and, at the time of such assignment, the additional amounts payable with respect to Taxes to such Assignee will not exceed such amounts payable to the transferor Lender, no such consent shall be required other than from the relevant Issuing Bank; and provided further that, in the case of an assignment of only part of such rights and obligations, the Assignee shall acquire a Total Exposure of not less than U.S.$3,000,000 and integral multiples of U.S.$1,000,000 in excess thereof. Upon execution and delivery of an Assignment and Assumption Agreement and payment by the Assignee to the transferor Lender of an amount equal to the purchase price agreed between such transferor Lender and such Assignee, such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment as set forth in such instrument of assumption (in addition to any Commitment previously held by it), and the transferor Lender shall be released from its obligations hereunder to a corresponding extent (except to the extent the same arose prior to the assignment), and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this paragraph (b), the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that a new Note is issued to the Assignee at the expense of the Assignee. In connection with any such assignment (other than a transfer by a Lender to one of its Affiliates), the transferor Lender (or in the case of Section 2.01(d) or 4.11, the Borrower), without prejudice to any claims the Borrower may have against any Defaulting Lender, shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of U.S.$2,000 and to the Issuing Bank a fee of U.S.$1,000.

(c) Nothing herein shall prohibit any Lender from pledging or assigning any Note to any Federal Reserve Bank of the United States in accordance with applicable law and without compliance with the foregoing provisions of this Section 15.06; provided, however, that such pledge or assignment shall not release such Lender from its obligations hereunder.

(d) Any Lender may, without any consent of the Borrower, the Administrative Agent, the Issuing Banks or any other third party at any time grant to one or more banks or other institutions (i) registered as a Foreign Financial Institution and (ii) resident (or having its principal office as a resident, if lending through a branch or agency) for tax purposes in a jurisdiction that is a party to an income tax treaty to avoid double taxation with Mexico on the date of such assignment and qualified to receive the benefits of said treaty and having (at the time such Lender or financial institution becomes a Participant) a withholding tax rate under such treaty applicable to payments hereunder no higher than that applicable to payments to such Lender (each a “Participant”) participating interests in

- 82 -

its Commitment or any or all of its Loans or its share of the Standby L/C Exposure. In the event of any such grant by a Lender of a participating interest to a Participant, whether or not upon notice to the Borrower, the Issuing Banks and the Administrative Agent, such Lender shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder, including the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, however, that such participation agreement may provide that such Lender will not agree to any modification, amendment or waiver of this Agreement extending the maturity of any Obligation in respect of which the participation was granted, or reducing the rate or extending the time for payment of interest thereon or reducing the principal thereof, or reducing the amount or basis of calculation of any fees to accrue in respect of the participation, without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Sections 4.07 and 4.10 with respect to its participating interest as if it were a Lender named herein; provided, however, that the Borrower shall not be required to pay any greater amounts pursuant to such Sections than it would have been required to pay but for the sale to such Participant of such Participant’s participation interest. An assignment or other transfer which is not permitted by paragraph (b) or (c) above shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this paragraph (d).

(e) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 15.06, disclose to the Assignee or Participant or proposed Assignee or Participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the Assignee or Participant or proposed Assignee or Participant shall agree to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender.

15.07 Right of Set-off. In addition to any rights and remedies of the Participating Lenders provided by law, each such Participating Lender shall have the right, without prior notice to the Borrower or the Guarantors, any such notice being expressly waived by the Borrower and the Guarantors to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower or the Guarantors hereunder (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final, including any amounts deposited pursuant to Section 11.02(a)(iii)), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Participating Lender, or any branch or agency thereof to or for the credit or the account of the Borrower or the Guarantors. Each Participating Lender agrees promptly to notify the Borrower, or such Guarantor, as the case may be, and the Administrative Agent after any such set-off and application made by such Participating Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application.

- 83 -

15.08 Confidentiality. Neither the Administrative Agent nor any Participating Lender shall disclose any Confidential Information to any other Person without the prior written consent of the Borrower, other than (a) to the Administrative Agent’s, or such Participating Lender’s Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 15.06(e), to actual or prospective Assignees and Participants, and then only on a confidential basis, (b) as required by any law, rule or regulation (including as may be required in connection with an audit by the Administrative Agent’s, or such Participating Lender’s independent auditors, and as may be required by any self-regulating organizations) or as may be required by or necessary in connection with any judicial process and (c) as requested by any state, federal or foreign authority or examiner regulating banks or banking. Notwithstanding the foregoing or anything contained in any Transaction Document to the contrary, the parties (and each employee, representative, or other agent of the parties) may disclose to any and all persons, without limitation of any kind, the tax treatment and any facts that may be relevant to the tax structure of the transactions contemplated by this Agreement, provided, however, that no party (and no employee, representative, or other agent thereof) shall disclose any other information that is not relevant to understanding the tax treatment and tax structure of such transactions (including the identity of any party and any information that could lead another to determine the identity of any party), or any other information to the extent that such disclosure could result in a violation of any federal or state securities law.

15.09 Use of English Language. All certificates, reports, notices and other documents and communications given or delivered pursuant to this Agreement shall be in the English language (other than the documents required to be provided pursuant to Section 5.01(e)(iii), Section 8.01 and Section 8.02 which shall be in the English language or in the Spanish language accompanied by an English translation or summary). Except in the case of the laws of, or official communications of, Mexico, the English language version of any such document shall control the meaning of the matters set forth therein.

- 84 -

(b) Each of the parties hereto hereby irrevocably waives, to the fullest extent it may effectively do so, any objection that it may now or hereafter have to the laying of venue of any such suit, action or proceeding in any such federal or New York State court and irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of any such suit, action or proceeding.

(c) Each of the parties hereto irrevocably waives the right to object, with respect to such claim, suit, action or proceeding brought in any such court, that such court does not have jurisdiction over it.

(d) Each of the parties hereto agrees, to the fullest extent it may effectively do so under applicable law, that a final judgment in any suit, action or proceeding of the nature referred to in paragraph (a) above brought in any such court shall be conclusive and binding upon such party and may be enforced in other jurisdictions by suit on the judgment or in any manner provided by law.

(e) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE ACTIONS OF ANY ARRANGER, THE ADMINISTRATIVE AGENT, ANY ISSUING BANK OR ANY LENDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

The appointment of the Process Agent shall be irrevocable until the appointment of a successor Process Agent. The Borrower and each Guarantor, further agrees to promptly appoint a successor Process Agent in New York City prior to the termination for any reason of the appointment of the initial Process Agent.

If the amount of Dollars so purchased is less than the sum originally due to such Issuing Bank, such Lender or the Administrative Agent, the Borrower and each of the Guarantors agree, to the fullest extent it may legally do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Issuing Bank, such Lender or the Administrative Agent against such resulting loss.

15.15 Counterparts. This Agreement may be executed in any number of counterparts and by the 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.

Loan Extension.

(i) Extension of Termination Date of Loan. The Borrower may, within 60 days, but not less than 45 days, prior to June 6, 2007 (the “Loan Extension Request Date”), by notice to the Administrative Agent, make written request of the Lenders to extend the Termination Date for an additional period of one (1) year. The Administrative Agent will give prompt notice to each of the Lenders of its receipt of any such request for extension of the Termination Date. Each Lender shall make a determination not later than 30 days prior to the then applicable Loan Extension Request Date (the “Loan Extension Consent Date”) as to whether or not it will agree to extend the Termination Date as requested (such approval of extension shall be an “Loan Extension Consent”); provided, however, that failure by any Lender to make a timely response to the Borrower’s request for extension of the Termination Date shall be deemed to constitute a refusal by such Lender to extension of the Termination Date.

(ii) Lender Not Consenting. If by any Loan Extension Consent Date the Borrower and the Administrative Agent have not received a Loan Extension Consent from any Lender, the Termination Date, as it relates to such Lender, shall not be extended, the Commitment of such Lender shall terminate on the Termination Date applicable to it and any Loans made by such Lender and all accrued and unpaid interest thereon shall be due and payable on such Termination Date. Upon the termination of the Commitment of any such Lender, unless this Agreement is amended as provided in Section 4.14(iv), the aggregate amount of the Commitments shall be reduced by the amount of such terminated Commitment, and the Commitment Percentage of each other Lender shall be adjusted to that percentage obtained by dividing the Commitment of such Lender by the aggregate amount of the Commitments after giving effect to such reduction as provided in the definition of “Commitment Percentage” unless an Additional Lender is added as provided in Section 4.14 (iv).

(iii) Other Lenders. No refusal by any one Lender to consent to any extension of the Termination Date shall affect the extension of the Termination Date as it may relate to the Commitment and Loans of any Lender that consents to such extension as provided in Section 4.14(i), and one or more Lenders may consent to the extension of the Termination Date as it relates to them notwithstanding any refusal by any other Lenders so to consent.

(iv) Additional Lender or Lenders. If any Lender does not deliver a Loan Extension Consent as provided in Section 4.14(i), upon the expiration of the Commitment of such Lender, the Borrower may, with the approval of the Administrative Agent, amend this Agreement as provided in Sections 15.02 and 15.06 to add one or more other Lenders as parties, with such Commitment or Commitments as may be agreed to by the Administrative Agent and such other Lender or Lenders; provided that such additions do not increase the aggregate amount of the Commitments to an amount greater than the aggregate amount of Commitments in effect immediately before such expiration or termination.

(v) Notice. The Administrative Agent shall promptly advise each Lender of any change in Commitment Percentages and shall promptly provide each of the Lenders with a copy of any amendment made pursuant to Section 4.14(iv).”
