aval) by the then existing Guarantors (subject to Section 6.11) substantially in the form of Exhibit A (each a “Note”), delivered to the Administrative Agent on behalf of each of the Lenders on or before the Initial Borrowing Date, appropriately completed and representing the full amount of each such Lender’s Tranche A Commitment or Tranche B Commitment, as the case may be; provided that in case of conflict between the terms of this Agreement and any such Note (including the amount of any principal or interest payable hereunder (whether such payment is made on a scheduled payment date, at stated maturity, by acceleration or otherwise), the manner of computation of any financial ratio used in determining the Applicable Margin, or the definition of “Applicable Margin”), the terms of this Agreement shall prevail and the Lenders shall not be entitled to claim amounts due under the Notes in excess of amounts due under this Agreement.

SECTION 2.3 Borrowings and Continuations. The Borrower shall give the Administrative Agent irrevocable notice of a request for the borrowing of any Loans hereunder, or the continuation of Loans hereunder, substantially in the form of Exhibit D (which notice must be received by the Administrative Agent prior to 12:00 noon, New York City time, at least three Business Days prior to the requested Borrowing Date for a Loan or, in the case of continuation of Loans, at least three Business Days prior to the end of the then current Interest Period for such Loans), specifying (a) the Tranche under which the Loans are to be made or continued, (b) the aggregate amount of the Loans to be borrowed or continued, (c) the requested Borrowing Date (or, as applicable, date of continuation, which date shall be an Interest Payment Date) and (d) the Interest Period applicable to each portion of such Loans (the “Notice of Borrowing/Continuation”). Each borrowing or continuation of Loans shall be in a principal amount of US$5,000,000 and integral multiples of US$1,000,000. Upon receipt of a Notice of Borrowing/Continuation, the Administrative Agent shall promptly notify each Lender that has a Commitment with respect to the relevant Tranche of the amount of each Loan to be made or to be continued by such Lender and the other relevant terms thereof. Not later than 1:00 p.m., New York City time, on the relevant Borrowing Date each such Lender shall make available to the Administrative Agent an amount in immediately available funds in Dollars equal to the Loan to be made by such Lender, at the Administrative Agent’s Office. Unless the Administrative Agent determines that any applicable condition specified in Article IV has not been satisfied, the Administrative Agent shall credit the amounts so received, in like funds, to the account of the Borrower maintained with the Administrative Agent in New York City. In furtherance of the foregoing, the Borrower hereby irrevocably authorizes the Administrative Agent to apply such amounts as the Borrower shall direct in the Notice of Borrowing/Continuation.

SECTION 2.4 Several Obligations; Remedies Independent. The obligations of the Lenders hereunder to make Loans and to make payments pursuant to Section 11.2(c) are several and not joint. The failure of any Lender to make any Loan or to make any payment under Section 11.2(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or to make its payment under Section 11.2(c). The amounts payable by the Borrower at any time hereunder and under the Notes to each Lender shall be a separate and independent debt, and each Lender shall be entitled to protect and enforce its individual rights arising out of this Agreement and the Notes independently of any other Lender, and it shall not be necessary for any other Lender or the Administrative Agent to consent to, or be joined as an additional party in, any proceedings to recover the payment of any overdue amounts.

Credit Agreement 21

SECTION 2.5 Repayment. (a) Tranche A Loans. The Borrower agrees to pay to the Administrative Agent for the account of each Tranche A Lender on each Tranche A Principal Payment Date a principal amount of the Tranche A Loans sufficient to reduce the outstanding Tranche A Loans to an amount at or below the Tranche A Commitments in effect on such Tranche A Principal Payment Date, after giving effect to the reductions thereof made pursuant to Section 2.7(c); provided that on the Tranche A Maturity Date, the then aggregate unpaid principal amount of the outstanding Tranche A Loans shall be paid in full.

(b) Tranche B Loans. The Borrower agrees to pay to the Administrative Agent for the account of each Tranche B Lender the full principal amount of the Tranche B Loans on the Tranche B Maturity Date.

SECTION 2.6 Optional Prepayments. (a) The Borrower may, without penalty or premium but subject to the indemnity provisions of Section 3.4, prepay all or a portion of the Loans, upon at least three Business Days’ prior irrevocable notice to the Administrative Agent specifying the Loans to be prepaid, their Tranche and their corresponding Borrowing Date and the date and amount of the prepayment; provided that each partial prepayment of any Tranche shall be in the minimum amount of US$5,000,000 and integral multiples of US$1,000,000 in excess thereof.

(b) Upon receipt of a notice of prepayment, the Administrative Agent shall promptly give notice thereof to each Lender holding a Loan to be prepaid. If such notice of prepayment is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to, and any other amounts then due on, each such date on the amount prepaid. Each optional prepayment shall be applied pro rata to the Loans made on the Borrowing Date and under the Tranche being prepaid in accordance with Section 2.13(a) and (with respect to Tranche A Loans) to the installments of principal pro rata across the remaining scheduled amortizations. Any Tranche B Loan prepaid may not be reborrowed.

SECTION 2.7 Reduction of Tranche A Commitments. (a) The Borrower may from time to time during the Tranche A Commitment Period, on at least three Business Days’ prior written notice received by the Administrative Agent (which shall promptly give notice thereof to each Tranche A Lender), permanently reduce the amount of the Tranche A Commitments to an amount not less than the aggregate principal amount of all outstanding Tranche A Loans (after giving effect to any payment or prepayment thereof). Any such reduction of Tranche A Commitments shall be in the minimum amount of US$5,000,000 and integral multiples of US$1,000,000 in excess thereof. The Borrower may at any time on like notice during the Tranche A Commitment Period terminate the Tranche A Commitments upon payment in full of the entire principal amount then outstanding of the Tranche A Loans, together with all accrued and unpaid interest thereon and all other amounts payable by the Borrower in connection therewith.

(b) All reductions of Tranche A Commitments shall be pro rata among the Tranche A Lenders according to their Tranche A Percentages.

(c) On (i) the first Tranche A Principal Payment Date, the Tranche A Commitments shall be automatically reduced by US$27,000,000; (ii) the second Tranche A Principal Payment Date, the Tranche A Commitments shall be automatically reduced by US$27,000,000; and (iii)

Credit Agreement 22

the final Tranche A Principal Payment Date, the Tranche A Commitments shall be automatically terminated.

SECTION 2.8 Mandatory Prepayments. (a) If on any date the Borrower or any its Subsidiaries shall receive Net Cash Proceeds from any Prepayment Event, the Borrower shall promptly, and in any event within ten Business Days, make a prepayment of the Loans in an aggregate amount equal to 100% of such Net Cash Proceeds; provided that the Borrower shall not be required to prepay the Loans as a result of a Prepayment Event under clause (a) or (b) of the definition thereof if (and to the extent in excess of the Prepayment Threshold Amount), for any fiscal year of the Borrower with respect to such Net Cash Proceeds received by the Borrower or any of its Subsidiaries from any of the events described in clause (a) or (b), respectively, of such definition that are in excess of US$1,000,000 (with amounts under each such clause (a) and clause (b) being separately calculated as in excess of US$1,000,000 (each, the “Prepayment Threshold Amount”)), the Borrower shall have delivered to the Administrative Agent a Reinvestment Notice prior to the date on which a prepayment would otherwise be required under this Section 2.8(a). If the Borrower delivers a Reinvestment Notice pursuant to the proviso to the immediately preceding sentence, such Net Cash Proceeds may be applied for the purposes set forth in such Reinvestment Notice and, if not so applied by the Reinvestment Prepayment Date with respect to the relevant Prepayment Event, shall be applied on such date to prepay the Loans in accordance with clause (c) below, until such outstanding Loans are repaid in full.

(b) Amounts to be applied in connection with prepayments made pursuant to clause (a) shall be applied (i) first to the Tranche B Loans and (ii) second, once all amounts due under the Tranche B Loans have been paid in full, to reduce permanently the Tranche A Commitments pro rata. After giving effect to such Commitment reductions, if the aggregate amount of Tranche A Loans outstanding would exceed the then amount of the Tranche A Commitments, the Borrower shall repay each such excess amount promptly (and, in any event, within ten Business Days) after the event giving rise to such reduction of the Tranche A Commitments.

(c) Each prepayment of Loans under this Section 2.8 shall be made together with accrued interest to the date of such prepayment on the amount so prepaid and any other amounts due pursuant to Section 3.4. Any amount prepaid under this Section 2.8 may not be reborrowed.

SECTION 2.9 Interest. (a) Loans. The Borrower shall pay to the Administrative Agent for the account of each Lender interest on the unpaid principal amount of the Loans for each day during each Interest Period for each such Loan until the date on which such Loans are paid in full at a rate per annum equal to Eurocurrency Rate determined for such Interest Period plus the relevant Applicable Margin.

(b) If all or a portion of (i) the principal amount of any Loan, (ii) any interest payable on the principal amount of any Loan (to the extent permitted by Applicable Law) or (iii) any fee payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the Default Rate from the date of such non-payment until paid in full and shall be payable on demand.

(c) Except as otherwise provided in clause (b), interest shall be payable in arrears on each Interest Payment Date for the applicable Loan.

Credit Agreement 23

SECTION 2.10 Computation of Interest. (a) Interest in respect of the Loans shall be calculated on the basis of a 360-day year for the actual days elapsed; provided that if interest with respect to any Loan shall apply at the Base Rate in accordance with this Agreement, such interest shall be calculated on the basis of a 365/366-day year for the actual days elapsed. The Administrative Agent shall, as soon as practicable, notify the Borrower and the Lenders of each determination of Eurocurrency Rate; provided that any failure to do so shall not relieve the Borrower of any liability hereunder.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower or any Lender, deliver to the Borrower or such Lender, as the case may be, a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.9(a).

(c) If, as a result of any restatement of or other adjustment to the financial statements of the Borrower or for any other reason, the Borrower or the Lenders determine that (i) the Consolidated Leverage Ratio as calculated by the Borrower as of any applicable date was inaccurate and (ii) a proper calculation of the Consolidated Leverage Ratio would have resulted in higher pricing for such period, the Borrower shall immediately and retroactively be obligated to pay to the Administrative Agent for the account of the applicable Lenders, promptly on demand by the Administrative Agent (or, after the occurrence of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States or similar proceeding under the Mexican Ley de Concursos Mercantiles, automatically and without further action by the Administrative Agent or any Lender), an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This paragraph shall not limit the rights of the Administrative Agent or any Lender, as the case may be, under Article VIII. The Borrower’s obligations under this paragraph shall survive the termination of the Commitments and the repayment of all other Obligations hereunder (such date, the “Obligation Termination Date”) up to and including the date that is the earlier of (i) the one year anniversary following the Obligation Termination Date and (ii) the date following the Obligation Termination Date of the delivery of the consolidated annual financial statements of the Borrower and its Consolidated Subsidiaries included in the Borrower’s 10-K filing with the Securities and Exchange Commission.

SECTION 2.11 Inability to Determine Interest Rate. (a) In the event that the Administrative Agent shall have reasonably determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the interbank eurodollar market, adequate means do not exist for ascertaining the Eurocurrency Rate applicable pursuant to Section 2.9(a), for any requested Interest Period, the Administrative Agent shall forthwith give notice by facsimile of such determination to the Borrower and each Lender at least one day prior to the last day of the current Interest Period. Thereafter, the obligation of the Lenders to make or maintain Eurocurrency Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Majority Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for the making or continuation of a Loan or, failing that, such Loan requested or continued by the Borrower will bear interest at the Base Rate.

Credit Agreement 24

SECTION 2.12 Fees. (a) Administration Fee. The Borrower agrees to pay to the Administrative Agent, for its account, all fees in such amount and in such manner as shall have been agreed to by the Administrative Agent and the Borrower in a separate fee letter (the “Administration Fee Letter”).

(b) Arrangement Fees. The Borrower agrees to pay to Banc of America Securities LLC and BBVA Securities Inc., for their account, all fees in such amount and in such manner as shall have been agreed to among the Joint Lead Arrangers and the Borrower in a separate fee letter dated as of April 23, 2007 (the “Arrangement Fee Letter”).

(c) Commitment Fee. (i) The Borrower agrees to pay to the Administrative Agent, for the account of each Tranche A Lender with a Tranche A Commitment, a commitment fee on the daily average unused portion of such Lender’s Tranche A Commitment for the period from and including the Effective Date to but excluding the last day of the Tranche A Commitment Period applicable to the Tranche A Commitments (the “Commitment Fee”) at a rate per annum determined based on the aggregate level of disbursements under Tranche A Loans in accordance with the table below:


Disbursement Level of Tranche A Loans		Commitment Fee Rate
Disbursement level is greater than 37%		0.50%
Disbursement level is greater than or equal to 12% and less than or equal to 37%		0.75%
Disbursement level is less than 12%		0.90%

(ii) The Commitment Fee shall be payable in arrears on each Commitment Fee Payment Date, for the period then ending for which such Commitment Fee shall not have been theretofore paid. The Commitment Fee shall be computed for the actual number of days elapsed on the basis of a year of 360 days.

SECTION 2.13 Pro Rata Treatment and Payments. (a) Except as otherwise provided herein, (i) each payment by the Borrower on account of principal of the Loans shall be made pro rata to the Lenders according to the respective outstanding principal amounts of the Loans then due and payable and (ii) each payment of interest on the Loans shall be made for the account of the Lenders pro rata in accordance with the respective amounts of interest on the Loans then due and payable to them.

(b) Payments of principal and interest in respect of Loans and payments of fees and other amounts due hereunder shall be made in Dollars. All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or set-off. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office and in immediately available funds, and shall be made not later than 2:00 p.m., New York City time, on the date specified herein. The Administrative Agent shall distribute such payments to the Lender

Credit Agreement 25

or Lenders entitled to receive the same promptly upon receipt in like funds as received. All payments received by the Administrative Agent after 2:00 p.m., New York City time, shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment on a Loan becomes due and payable on a day other than a Business Day therefor, the maturity thereof shall be extended to the next succeeding Business Day for such Loan (and such extension of time shall be reflected in computing interest or fees, as the case may be) unless, with respect to Loans, the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Loan that such Lender will not make available to the Administrative Agent such Lender’s share of such Loan, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.1 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Loan available to the Administrative Agent, then the applicable Lender and the Borrower, upon receipt of notice from the Administrative Agent of such failure, severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for 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) in the case of a payment to be made by such Lender, the Overnight Rate and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to the Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Commitment to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Commitment. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Overnight Rate.

(e) Except as otherwise set forth herein, all payments made under this Agreement or any other Loan Document shall be applied first (in each case on a pro rata basis to the recipients thereof based upon the amounts then owed to them) to pay fees and expenses due to the Beneficiaries under the Loan Documents, then to pay accrued and unpaid interest on the Loans, then to pay principal of the Loans and then to pay any and all other amounts payable to the Beneficiaries under the Loan Documents.

Credit Agreement 26

SECTION 2.14 Set-Off; Sharing of Payments, Etc. (a) Without limiting any of the obligations of the Loan Parties or the rights of any Beneficiary under the Loan Documents, if the Borrower shall fail to pay when due (whether at stated maturity, by acceleration or otherwise) any amount payable by it hereunder or under any other Loan Document, then (to the extent not in violation of an Applicable Law) each Beneficiary may, without prior notice to any Loan Party (which notice is expressly waived by it to the fullest extent permitted by Applicable Law), set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final, in any currency, matured or unmatured) at any time held or any other Indebtedness owing by such Beneficiary or any of its Affiliates (in each case, including any branch or agency thereof) to or for the credit or account of the Borrower or any other Loan Party. Each Beneficiary shall promptly provide written notice of any such set-off by it to the Borrower and the Administrative Agent; provided that failure by such Beneficiary to provide such notice shall not give the Borrower any cause of action or right to damages or affect the validity of such set-off and application.

(b) If, other than as expressly provided elsewhere herein, any Beneficiary shall obtain on account of the Obligations owing to it hereunder or in respect of its Loans any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its share of payments on account of the Obligations obtained by all the Beneficiaries, such Beneficiary shall forthwith (i) notify the Administrative Agent of such fact, and (ii) purchase from the other Beneficiaries such participations in such amounts made by them as shall be necessary to cause such purchasing Beneficiary to share the excess payment ratably with each of them; provided, that if all or any portion of such excess payment is thereafter recovered from the purchasing Beneficiary, such purchase shall to that extent be rescinded and each other Beneficiary shall repay to the purchasing Beneficiary the purchase price paid therefor, without interest. The provisions of this Section 2.14(b) shall not be construed to apply to (A) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased pursuant to this Section 2.14 and will in each case notify the Lenders and the Borrower following any such purchases.

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Beneficiary acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff permitted hereunder and counterclaim with respect to such participation as fully as if such Beneficiary were a direct creditor of such Loan Party in the amount of such participation.

ARTICLE III
YIELD PROTECTION, ETC.

SECTION 3.1 Taxes. (a) All payments made by each Loan Party under this Agreement and any Notes shall be made free and clear of, and without deduction for or on account of, any present or future Taxes, including Other Taxes (but excluding any tax imposed on or measured by the net income or net profits or capital (or any franchise or similar tax imposed in lieu thereof) of a beneficiary of such payment (each a “Payee”) pursuant to the laws of the jurisdiction (or any political subdivision thereof) in which it is organized or the jurisdiction (or any political

Credit Agreement 27

subdivision thereof) in which the Lending Office of such Lender is located and any withholding taxes to the extent imposed by reason of any Payee, that is not a Mexican Financial Institution, or its assignees or participants, if any, failing to make reasonable commercial efforts, consisting of timely making any necessary filing and taking related action, to maintain its registration for the purposes of Article 195(I) or Article 196(II) of the Mexican Income Tax Law (Ley del Impuesto Sobre la Renta) or any successor provision with Hacienda (collectively, the “Excluded Taxes”)). If any such Taxes that are not Excluded Taxes (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to any Payee hereunder (subject to the right of such Loan Party to contest any such requirement in good faith, so long as proper reserves are maintained and each Payee hereunder is paid the full amounts payable hereunder including any additional amounts payable), such Loan Party shall pay such Non-Excluded Taxes, including Other Taxes, to the appropriate taxing authority, and the amounts payable to each such Payee shall be increased by such additional amounts (the “Additional Amounts”) necessary to yield to such Payee (after payment of all Non-Excluded Taxes, Other Taxes and Additional Amounts, including any of the foregoing levied on Additional Amounts) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement in the absence of such payments or deductions; provided that no such Additional Amounts shall be payable in respect of any Taxes that would not have been imposed but for a failure by a Payee to provide the documents required by Section 3.1(c) strictly pursuant to the terms of, and only in the circumstances specified in, Section 3.1(c), in excess of the Additional Amounts that would have been payable had such documents been provided. In addition, such Loan Party shall pay any Other Taxes to the relevant Governmental Authority in accordance with Applicable Law. Whenever any Non-Excluded Tax or Other Tax is payable by a Loan Party, as promptly as possible thereafter, such Loan Party shall send to the Administrative Agent, for the account of such Payee, a certified copy by a Responsible Officer of such Loan Party of a stamped filed receipt showing payment thereof or such other document reasonably satisfactory to such Payee showing payment thereof. If such Loan Party fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, such Loan Party shall indemnify the affected Payee for any incremental taxes, interest, penalties, loss, liability, claim or expense (including legal fees and expenses) that may become payable by any such Payee as a result of any such failure. This indemnity and agreement shall survive termination of the Agreement and payment of the Loans.

(b) Subject to the last sentence of Section 3.1(c) below, each Loan Party shall indemnify the Administrative Agent and each Payee, within 10 days after written demand therefor, for the full amount of any Non-Excluded Taxes or Other Taxes paid by the Administrative Agent or such Payee on or with respect to any payment by or on account of any obligation of such Loan Party hereunder (including Non-Excluded Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 3.1) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Non-Excluded Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to such Loan Party by a Payee, or by the Administrative Agent on its own behalf or on behalf of a Payee, shall be conclusive absent manifest error.

(c) Each Payee that is not a Mexican Financial Institution shall from time to time, at the request of the Borrower or the Administrative Agent, furnish to the Borrower or the

Credit Agreement 28

Administrative Agent, as the case may be, such documentation required under Applicable Law as may be required to establish any available exemption from, or reduction in the amount of, otherwise applicable Non-Excluded Taxes; provided that (i) such documentation is consistent with Applicable Law and (ii) such documentation would not, in the judgment of such Payee, require such Payee to disclose any confidential or proprietary information or otherwise be disadvantageous to such Payee; provided that such documentation shall not be considered disadvantageous solely by virtue of administrative inconvenience to such Payee. The Borrower and the Administrative Agent shall be entitled to rely upon the accuracy of any such documentation furnished to it by any Payee that is not a Mexican Financial Institution and shall have no obligation to indemnify such Payee for any incremental taxes, interest or penalties that may become payable by such Payee solely as a result of any inaccuracy contained therein or the Payee’s failure to furnish such documentation.

SECTION 3.2 Illegality. Notwithstanding any other provisions herein, if any Applicable Law or any change therein or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain a Loan as contemplated by this Agreement, then such Lender may give notice thereof to each of the Borrower and the Administrative Agent and, upon the giving of such notice (a) the Commitments of such Lender hereunder to make further Loans shall forthwith be canceled (with, unless the Borrower replaces such Lender in accordance with Section 3.6 within ten Business Days following such notice, a corresponding reduction of the aggregate amount of the Commitments under the Tranche of the canceled Commitment) and/or (b) if such Applicable Law shall so mandate, such Lender’s Loan shall be prepaid in full by the Borrower, together with accrued and unpaid interest thereon and all other amounts payable by the Borrower under this Agreement, on or before such date as shall be mandated by such Applicable Law (such prepayment not being shared as described in Section 2.13 with any Lenders not so affected); provided that if it is lawful for such Lender to maintain its Loan through the last day of the then current Interest Period, as the case may be, such payment shall be made on such date.

SECTION 3.3 Additional Costs. (a) If, after the Effective Date, and as a result of the adoption of any law, regulation, treaty or official directive or request (whether or not having the force of law) or any change therein or any introduction thereof (which such change or introduction is publicly announced through official governmental, regulatory or other customary means after the Effective Date) or compliance therewith by the Borrower, the Administrative Agent or any Lender (or any corporation Controlling such Lender) including those relating to taxation, reserves, special deposit, cash ratio, liquidity, capital adequacy or Eurocurrency Liabilities, if applicable, or other requirement or any other form of banking or monetary requirements or controls, any of the following shall occur:

(i) the cost to any Lender of maintaining its Loans is increased by an amount determined by such Lender to be material; or

(ii) any amount receivable by any Lender is reduced by an amount determined by such Lender to be material as a result of maintaining its Loans; or

(iii) the rate of return on such Lender’s (or its Controlling corporation’s) capital is reduced as a consequence of its obligations hereunder below that which such Lender could have achieved but for such adoption, change or introduction (taking into

Credit Agreement 29

consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material;

in the case of each of clauses (i), (ii) and (iii) other than any increase in or incurrence of cost, reduction in yield or other return or additional payment resulting from Excluded Taxes, then and in each such case:

(A) such Lender or the Administrative Agent (an “Affected Party”) shall notify the Borrower through the Administrative Agent in writing of such event promptly upon its becoming aware of the event entitling it to make a claim; and

(B) within a reasonable period (not exceeding 15 Business Days) following any demand from time to time by such Affected Party through the Administrative Agent (with a copy contemporaneously sent to the Borrower), the Borrower shall pay to the Administrative Agent, for the account of such Affected Party, such amount as shall compensate such Affected Party for such increased cost, reduced amount receivable or reduction in rate of return (excluding anticipated profits unrelated to those measured by the Applicable Margin, the Default Rate, if applicable, and the Commitment Fee). The certificate of such Affected Party specifying the amount of such compensation shall be conclusive save in the case of manifest error.

(b) If an Affected Party shall request compensation under this Section 3.3, such Affected Party shall furnish to the Borrower a statement setting forth the basis for requesting such compensation.

(c) The covenants and agreements set forth in this Section 3.3 shall survive the termination of this Agreement and the payment of the outstanding Loans. Failure or delay on the part of any Affected Party to demand compensation pursuant to this Section 3.3 shall not constitute a waiver of such Affected Party’s right to demand compensation; provided that the Borrower shall not be required to compensate an Affected Party, as applicable, pursuant to this Section 3.3 for any increased costs or reductions incurred more than 90 days prior to the date that such Affected Party notifies the Borrower of the event giving rise to such increased costs or reductions and of such Affected Party’s intention to claim compensation therefor; and provided further that, if the event giving rise to such increased costs or reduction is retroactive, then the 90 day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 3.4 Funding Losses. The Borrower agrees to indemnify each Lender and to hold such Lender harmless from any actual loss or expense (excluding loss of profit) which such Lender may sustain or incur as a consequence of (a) default by the Borrower in payment when due (by acceleration or otherwise) of the principal amount of or interest on the Loans of such Lender, (b) default by the Borrower in making a borrowing of Loans or any prepayment after the Borrower has given a notice in accordance with Section 2.3 or 2.6 and (c) the making by the Borrower of a prepayment of the Loans on a day which is not the last day of an Interest Period (whether or not the Administrative Agent or such Lender has previously consented to such prepayment), including any such loss or expense arising from interest or fees payable by such Lender to lenders of funds obtained by it in order to maintain its Loans hereunder as set forth in a

Credit Agreement 30

certificate of such Lender delivered to the Borrower through the Administrative Agent. This covenant shall survive termination of this Agreement and payment of the Loans.

SECTION 3.5 Change of Lending Office. Each Lender that is not a Mexican Financial Institution agrees that, upon the occurrence of any event giving rise to the operation of Section 3.1(a) (other than the imposition of the Mexican withholding taxes expected, based upon the identity and place of residence of each Lender on the Effective Date, or the Mexican withholding taxes applicable to interest payments made to an Eligible Assignee), 3.2 or 3.3(a) as to it and upon request by the Borrower, it will use its commercially reasonable efforts to avoid or minimize the consequences of such event if such action shall not, in the judgment of such Lender, as the case may be, be illegal or economically or otherwise disadvantageous to it. If such Lender is entitled to compensation for the events specified under Section 3.1 (other than as set forth in the preceding sentence) or 3.3(a), or the Borrower is required to make a prepayment as a result of the operation of Section 3.2, such Lender shall use commercially reasonable efforts for a period of 30 days to designate a different Lending Office for any Obligation affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation (except as set forth in the preceding sentence) and will not, in the sole opinion of such Lender, result in any economic, legal or regulatory or other disadvantage to such Lender or any of its Affiliates.

SECTION 3.6 Replacement of Lenders. The Borrower shall be permitted, at its sole expense and effort, to replace with a replacement financial institution or Eligible Assignee any Lender (a) that requests reimbursement for amounts owing pursuant to Section 3.1(a) (but only if such Lender is (i) not a Mexican Financial Institution and (ii) a financial institution not registered with Hacienda for purposes of Article 195(I) or Article 196(II) of the Mexican Income Tax Law or any successor provision thereof and, in the case of a financial institution registered with Hacienda for purposes of Article 195(I) of the Mexican Income Tax Law, not a resident of (or, if acting through a branch or agency, does not have its principal office in) a country with which Mexico has entered into a treaty for the avoidance of double taxation) or 3.3(a), (b) to which the Borrower is required to make a prepayment or commitment reduction as a result of the operation of Section 3.2, (c) that defaults in its obligation to make its Loan hereunder or (d) that fails to consent to an election, consent, amendment, waiver or other modification to this Agreement or other Loan Document requiring more Lenders than the Majority Lenders’ consent and such election, consent, amendment, waiver or other modification is otherwise consented to by Lenders holding more than 66 2/3% of the sum of (i) all undrawn Commitments on such date and (ii) all Loans outstanding on such date, without giving effect to the Loans and undrawn Commitments attributable to such Lender; provided that (A) such replacement does not conflict with any Applicable Law, (B) no Default or Event of Default shall have occurred and be continuing at the time of such replacement, (C) prior to any such replacement, such Lender shall have taken no action under Section 3.5 which has eliminated the continued need for payment of amounts owing pursuant to Section 3.1(a) or 3.3(a) or the operation of Section 3.2, (D) the replacement financial institution shall purchase, at par, the Loans and other amounts (including accrued and unpaid interest) owing to such replaced Lender on or prior to the date of replacement, (E) the Borrower shall be liable to such replaced Lender under Section 3.4 if the Loans owing to such replaced Lender shall be purchased other than on the last day of an Interest Period relating to such Loans, (F) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (G) the replaced Lender shall be obligated to make such replacement without recourse in accordance with the provisions of Section 11.8 (provided that

Credit Agreement 31

the Borrower shall be obligated to pay the registration and processing fee referred to therein), (H) until such time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 3.1(a) or 3.3(a), as the case may be, and (I) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

SECTION 5.13 Proper Form. The Loan Documents are (or, in the case of any Note, will be, upon the issuance thereof in accordance herewith) in proper legal form for the enforcement thereof in Mexico, against each Loan Party; provided that, if any legal proceedings are brought in a court of Mexico for the enforcement against a Loan Party, of this Agreement, the Fee Letters or any other Loan Document that is executed in a language other than Spanish, a Spanish translation of such document prepared by a translator approved by the Mexican court would have to be approved by such court after such Loan Party has been given the opportunity to be heard with respect to the accuracy of the translation, and proceedings would thereafter be based on the translated documents. To ensure the legality, validity, enforceability or admissibility in evidence of this Agreement, the Fee Letters or any other Loan Document in Mexico it is not necessary that this Agreement, the Fee Letters or any other Loan Document be filed or recorded with any Governmental Authority in Mexico or be notarized, or that any stamp or similar tax be paid on or in respect of this Agreement, the Fee Letters or any other Loan Document.

(b) Each Loan Party owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by it does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

No part of the proceeds of any Loan will be used for “buying” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the Regulations of the Board of Governors of the Federal Reserve System. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U.

SECTION 9.1 Guarantees. (a) For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and to induce the Lenders to enter into this Agreement, each of the Guarantors, jointly and severally, hereby absolutely, unconditionally and irrevocably Guarantees the full and punctual payment and performance (whether at stated maturity, upon acceleration or otherwise) of all Obligations, in each case as primary obligor and not merely as surety and with respect to all such Obligations howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due (collectively, the “Guaranteed Obligations”). This is a guarantee of payment and not merely of collection.

(f) any other act or omission to act or delay of any kind by any Loan Party, the Administrative Agent or any other Person or any other circumstance whatsoever that might, but for the provisions of this Section 9.2, constitute a legal or equitable discharge of the obligations of any Loan Party under the Loan Documents.

SECTION 9.3 Discharge Only upon Payment in Full; Reinstatement In Certain Circumstances. The obligations of the Guarantors hereunder shall remain in full force and effect until all of the Borrower’s Obligations under the Loan Documents shall have been paid or otherwise performed in full and all of the Commitments shall have terminated. If at any time any payment made under this Agreement or any other Loan Document is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, concurso mercantil, reorganization, insolvency, custodianship, liquidation, receivership, dissolution, winding up or relief of debtors or similar event of a Loan Party or any other Person or otherwise, then the obligations of the Guarantors hereunder with respect to such payment shall be reinstated at such time as though such payment had been due but not made at such time.

SECTION 9.4 Waiver by the Guarantors. (a) Each of the Guarantors hereby irrevocably and unconditionally waives, to the fullest extent permitted by Applicable Law: (i) notice of acceptance of the Guarantee provided in this Article IX and notice of any liability to which this Guarantee may apply, (ii) all notices that may be required by Applicable Law or otherwise to preserve intact any rights of any Beneficiary against any Loan Party, including any demand, presentment, protest, proof of notice of non-payment, notice of any failure on the part of any Loan Party to perform and comply with any covenant, agreement, term, condition or provision of any agreement and any other notice to any other party that may be liable in respect of the Obligations Guaranteed hereby (including any Loan Party) except any of the foregoing as may be expressly required hereunder, (iii) any right to the enforcement, assertion or exercise by any Beneficiary of any right, power, privilege or remedy conferred upon such Person under the Loan Documents or otherwise, (iv) any requirement that any Beneficiary exhaust any right, power, privilege or remedy, or exhaust or apply any assets of the Borrower or any other Guarantor or mitigate any damages resulting from a default, under any Loan Document, or against any Loan Party or any other Person under or in respect of any Loan Document or otherwise (including any requirement that any action be initiated and/or completed against the Borrower prior to any action being initiated against any Guarantor), and (v) any requirement that claims or liabilities be divided among Guarantors.

(b) Each of the Guarantors expressly acknowledges that the Guarantee provided in this Article IX is governed by the laws of the State of New York and expressly agrees that any rights and privileges that it might otherwise have under the laws of Mexico shall not be applicable to this Guarantee, including, but not limited to, any benefit of orden, excusión, división, quita, novación, espera and modificación which may be available to it under articles 2813, 2814, 2815, 2817, 2818, 2820, 2821, 2822, 2823, 2827, 2836, 2840, 2842, 2845, 2846, 2847, 2848, 2849 or any other applicable articles of the Federal Civil Code of Mexico and the

SECTION 9.6 Stay of Acceleration. If acceleration of the time for payment of any amounts payable under the Loan Documents is stayed due to any event described in Section 8.1(f), then all such amounts otherwise subject to acceleration under this Agreement shall nonetheless be payable by the Guarantors hereunder immediately upon demand by the Administrative Agent.

Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Loan Party or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Credit Agreement 55

writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or Applicable Law; and

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 8.2 and 11.3) or (ii) in the absence of its own gross negligence or willful misconduct.

The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for any Loan Party), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 10.5 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document

In addition, each Lender agrees to notify the Administrative Agent from time to time to ensure that the Administrative Agent has on record (i) an effective address, contact name, telephone number, telecopier number and electronic mail address to which notices and other communications may be sent and (ii) accurate wire instructions for such Lender.

(e) Reliance by the Administrative Agent and Lenders. The Administrative Agent and the Lenders shall be entitled to rely and act upon any notices purportedly given by or on behalf of any Loan Party even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. Each Loan Party agrees, jointly and severally, to indemnify the Administrative Agent and each Lender and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of any Loan Party. All telephonic notices to and other telephonic communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording.

SECTION 11.6 Table of Contents; Headings. The table of contents and captions and section headings appearing herein are inserted for convenience only and shall not be deemed to affect the meaning or construction of any of the provisions hereof.

SECTION 11.7 Survival. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Loan, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Commitment shall remain outstanding. The obligations of the Borrower under Sections 3.1(b), 3.3, 3.4, and 11.2 and the obligations of the Lenders under Section 11.2(c) shall survive the repayment of the Loans and the termination of the Commitments and, in the case of any Lender that may assign any interest in its Commitment or Loan hereunder, shall survive the making of such assignment with respect to the assigning Lender, notwithstanding that such assigning Lender may cease to be a “Lender” hereunder; provided that any Lender’s obligations under Section 11.2(c) shall only apply to the extent that the event with respect to which any indemnification is payable thereunder occurred at the time that such Lender maintained a Loan or Commitment hereunder.

Credit Agreement 63

SECTION 11.8 Successors and Assigns. (a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that no Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer all or any portion of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of clause (b), (ii) by way of participation in accordance with the provisions of clause (d), or (iii) by way of pledge or assignment of a security interest subject to the restrictions of clause (f) (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in clause (d) and, to the extent expressly contemplated hereby, the Related Parties of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that:

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than, (A) with respect to Tranche A Loans, US$5,000,000 and (B) with respect to Tranche B Loans, US$1,000,000, in each case unless the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met;

(ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned;

(iii) any assignment of a Commitment or a Tranche A Loan must be approved by the Administrative Agent (which approval shall not be unreasonably withheld or delayed) unless the Person that is the proposed assignee is itself a Lender or an Affiliate of a Lender (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

Credit Agreement 64

(iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of US$3,500 and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause (c), from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.1, 3.3, 3.4 and 11.2 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this clause (b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with clause (d).

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement and the other Loan Documents, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower at any reasonable time and from time to time upon reasonable prior notice. In addition, at any time that a request for a consent for a material or substantive change to the Loan Documents is pending, any Lender may request and receive from the Administrative Agent a copy of the Register.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or any Loan Party or any Loan Party’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Loan Parties, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso

Credit Agreement 65

to Section 11.3 that affects such Participant. Subject to clause (e), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.3 and 3.4 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to clause (b). To the extent permitted by Applicable Law, each Participant also shall be entitled to the benefits of Section 2.14(a) as though it were a Lender if such Participant agrees to be subject to Section 2.14(b) as though it were a Lender.

(e) Limitation upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.1 or 3.3 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note(s), if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any Applicable Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

SECTION 11.9 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by Applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by Applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

SECTION 11.10 Submission to Jurisdiction; Venue; Service; Waiver of Jury Trial.

(a) EACH OF THE PARTIES HERETO (AND ITS SUCCESSORS AND ASSIGNS) (i) AGREES THAT ANY CLAIM, SUIT, ACTION OR PROCEEDING BROUGHT BY ANY PARTY OR SUCCESSOR THERETO ARISING OUT OF OR WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT SHALL BE SUBJECT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (IN EACH

Credit Agreement 66

CASE LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK CITY), TO THE JURISDICTION OF ANY COMPETENT COURT IN THE PLACE OF ITS CORPORATE DOMICILE IN RESPECT OF ACTIONS BROUGHT AGAINST IT AS A DEFENDANT AND TO APPELLATE COURTS THEREFROM AND EACH OF THE PARTIES HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO SUCH JURISDICTION FOR SUCH PURPOSE AND (ii) TO THE FULLEST EXTENT PERMITTED BY LAW, (A) IRREVOCABLY WAIVES ANY OBJECTION IT MAY HAVE AT ANY TIME TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT BROUGHT IN ANY SUCH COURT, (B) IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (C) 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 AND (D) IRREVOCABLY WAIVES ANY RIGHT TO WHICH IT MAY BE ENTITLED ON ACCOUNT OF PLACE OF RESIDENCE OR DOMICILE. EACH OF THE PARTIES HERETO HEREBY EXPRESSLY AND IRREVOCABLY WAIVES ALL RIGHTS OF JURISDICTION IN ANY SUCH ACTION OR PROCEEDING, WHICH IT MAY NOW OR HEREAFTER BE AFFORDED BY LAW, IN ANY OTHER FORUM. EACH OF THE PARTIES HERETO FURTHER AGREES THAT A FINAL JUDGMENT IN ANY SUCH SUIT, ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY MANNER PROVIDED BY LAW.

(b) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

(c) FOR THE PURPOSE OF PROCEEDINGS IN THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK (IN EACH CASE LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK CITY), EACH LOAN PARTY HEREBY IRREVOCABLY DESIGNATES AS OF THE EFFECTIVE DATE CT CORPORATION SYSTEM (“PROCESS AGENT”) WITH OFFICES CURRENTLY LOCATED AT ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ AS ITS AGENT FOR SERVICE OF PROCESS. IN THE EVENT THAT SUCH AGENT OR ANY SUCCESSOR SHALL CEASE TO BE LOCATED IN THE BOROUGH OF MANHATTAN, EACH LOAN PARTY SHALL PROMPTLY AND IRREVOCABLY BEFORE THE RELOCATION OF SUCH AGENT FOR SERVICE OF

Credit Agreement 67

PROCESS, IF PRACTICABLE, OR PROMPTLY THEREAFTER DESIGNATE A SUCCESSOR AGENT, WHICH SUCCESSOR AGENT SHALL BE LOCATED IN THE BOROUGH OF MANHATTAN, AND NOTIFY THE ADMINISTRATIVE AGENT THEREOF, TO ACCEPT ON ITS BEHALF SERVICE OF ANY AND ALL PROCESS OR OTHER DOCUMENTS WHICH MAY BE SERVED IN ANY ACTION OR PROCEEDING IN ANY OF SUCH COURTS AND FURTHER AGREES THAT SERVICE UPON SUCH AGENT SHALL CONSTITUTE VALID AND EFFECTIVE SERVICE UPON EACH SUCH LOAN PARTY AND THAT FAILURE OF ANY SUCH AGENT TO GIVE ANY NOTICE OF SUCH SERVICE TO SUCH LOAN PARTY SHALL NOT AFFECT THE VALIDITY OF SUCH SERVICE OR ANY JUDGMENT RENDERED IN ANY ACTION OR PROCEEDING BASED THEREON. EACH OF THE PARTIES HERETO AGREES THAT SERVICE OF ANY AND ALL SUCH PROCESS OR OTHER DOCUMENTS ON SUCH PERSON MAY ALSO BE EFFECTED BY REGISTERED MAIL TO ITS ADDRESS AS SET FORTH IN SECTION 11.5 OR SCHEDULE 11.5. WITH RESPECT TO EACH LOAN PARTY, SERVICE OF ANY AND ALL SUCH PROCESS OR OTHER DOCUMENTS TO THE PROCESS AGENT OR SUCH OTHER AGENT FOR SERVICE OF PROCESS DESIGNATED BY SUCH LOAN PARTY IN ACCORDANCE WITH THIS AGREEMENT SHALL CONSTITUTE VALID AND EFFECTIVE SERVICE ONLY IF MADE IN PERSON TO THE PROCESS AGENT OR SUCH OTHER AGENT FOR SERVICE OF PROCESS.

SECTION 11.11 Judgment Currency. All payments made under this Agreement and the Notes shall be made in Dollars (to the extent required by the terms hereof, the applicable “Agreement Currency”), as applicable, and, if for any reason any payment made hereunder or under any Note is made in a currency (the “Other Currency”) other than the applicable Agreement Currency, then to the extent that the payment actually received by the relevant Beneficiary, when converted into the applicable Agreement Currency at the Rate of Exchange (as defined below) on the date of payment (or, if conversion on such date is not practicable, as soon thereafter as it is practicable for such Beneficiary to purchase the applicable Agreement Currency) falls short of the amount due under the terms of this Agreement or any Note, the Loan Parties shall, as a separate and independent obligation of the Loan Parties, indemnify such Beneficiary and hold such Beneficiary harmless against the amount of such shortfall. As used in this Section 11.11, the term “Rate of Exchange” means the rate at which the Beneficiary is able on the relevant date to purchase the applicable Agreement Currency with the Other Currency and shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into, the applicable Agreement Currency.

SECTION 11.12 Execution in 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 and delivered shall be deemed to be an original and all of which taken together shall constitute one and the same instrument.

SECTION 11.13 Waiver of Immunities. To the extent that any Loan Party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its Property, such Loan Party hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the other Loan Documents. The foregoing waiver is intended to be effective to the fullest extent now or hereafter permitted by Applicable Law.

Credit Agreement 68

SECTION 11.14 Severability. To the fullest extent permitted by law, any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction, and the remaining portion of such provision and all other remaining provisions hereof will be construed to render them enforceable.

SECTION 11.15 Treatment of Certain Information; Confidentiality. The Administrative Agent and each of the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and be required to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by Applicable Laws or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement with each Person receiving the Information containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Lender, or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower.

For purposes of this Section, “Information” means all information received from any Loan Party or any Subsidiary relating to any Loan Party or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by such Loan Party or Subsidiary; provided that, in the case of information received from a Loan Party or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

The Administrative Agent and each of the Lenders acknowledges that (a) the Information may include material non-public information concerning a Loan Party or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with Applicable Law, including Federal and state securities laws.

SECTION 11.16 No Waiver; Remedies. No failure on the part of the Administrative Agent or any of the Lenders to exercise, and no delay in exercising, any right hereunder shall

Credit Agreement 69

operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 11.17 Entire Agreement. As of the Effective Date, this Agreement and the other Loan Documents (including the Fee Letters with respect to the matters covered thereby) constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof.

SECTION 11.18 USA PATRIOT Act. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.
