constitute prima facie evidence of the accuracy of the information so recorded; provided that the failure of a Lender to make, or an error in making, a notation thereon with respect to any Loan shall not limit or otherwise affect the Obligations of any Credit Party hereunder or under any such Note to such Lender.

(b) Promptly upon: (i) a conversion of Loans from LIBOR Loans to Base Rate Loans or vice versa in accordance with Section 2.6(g), (ii) the election of the Borrower in accordance with Section 2.6(e) to change the duration of the Interest Period, (iii) the addition of a new Guarantor, (iv) any change in organizational structure pursuant to Section 6.2(i) and/or (v) any assignment of Loans pursuant to Section 10.8, the Borrower and each Guarantor (por aval) shall, upon the request of the Administrative Agent, at the expense of the Borrower, promptly execute and deliver to the Administrative Agent for the account of each of the relevant Lenders, in exchange for the Note evidencing the relevant Loans of such Lender theretofore delivered to such Lender, a new Note or Notes payable to such Lender and/or such Lender’s assignee, as applicable, dated the Closing Date, in a principal amount equal to the principal amount then outstanding of such Note and otherwise duly completed.

SECTION 2.3 Procedure for Borrowing. (a) The Borrower shall deliver to the Administrative Agent (by no later than 9:00 a.m. (New York City time) on the Closing Date) an irrevocable written notice in the form of a Notice of Borrowing, requesting that the Loans be made on the Closing Date. Such Notice of Borrowing: (i) shall be delivered in accordance with the last paragraph of Section 4.1 and (ii) shall specify: (A) the requested amounts of the Loans to be borrowed by the Borrower, and (B) for the Loans, the Type of Loans requested and if the Loans are LIBOR Loans, the Interest Period therefor. The Administrative Agent will notify each Lender on or before the Closing Date of the borrowing request.

(b) Subject to the conditions precedent set forth in Article IV, each Lender severally agrees to make the amount of its Pro Rata Share of the requested Loan available to the Administrative Agent for the account of the Borrower at the Administrative Agent’s applicable Payment Office by 10:00 a.m. (New York City time) on the Closing Date in funds immediately available to the Administrative Agent. Upon fulfillment of the conditions precedent to disbursing the Loans in Article IV, the Administrative Agent shall deliver the proceeds of the Loans to (or on behalf of) the Borrower as provided in the Notice of Borrowing.

SECTION 2.4 Prepayments:

(a) Optional Prepayments. The Borrower shall have the right to prepay the Loans, in whole or in part, without premium or penalty, from time to time on the following terms and conditions: (i) the Borrower shall give the Administrative Agent irrevocable written notice at its Notice Office (of which the Administrative Agent shall promptly notify each of the Lenders) of its intent to prepay the Loans and the amount of such prepayment, which notice shall be given by the Borrower at or prior to 10:00 a.m. (New York City time) at least three Business Days (but no more than 30 days) before the date of such prepayment, (ii) each partial prepayment of Loans shall be in an aggregate principal amount of at least $10,000,000 and, if greater, in an integral multiple of $1,000,000, (iii) each prepayment of Loans pursuant to this paragraph shall be applied to the Loans of each Lender in accordance with its Pro Rata Share and (to the extent that

Bredie Credit Agreement 23

such prepayment does not prepay all of the Loans) shall be applied to reduce the remaining scheduled principal repayments of the Loans on a pro rata basis and (iv) each prepayment of Loans pursuant to this paragraph shall be applied as provided in Section 2.9(d); it being understood that the Borrower shall deliver to the Administrative Agent such additional amounts (if any) necessary so that the amount allocated to the principal prepayment of the Loans is the amount indicated to be prepaid on the notice of prepayment. If such notice is given by the Borrower, then 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 such date on the amount prepaid and any amounts required pursuant to Section 3.4.

(b) Mandatory Prepayments. The Borrower shall make mandatory prepayments of the Loans as follows:

(i) Asset Sales. Other than with respect to the sale, assignment, transfer, conveyance, lease or other disposition of Property in the Ordinary Course of Business or to another Credit Party so long as such transaction is in compliance with Section 6.2(e), the Borrower shall prepay the outstanding Loans in an aggregate principal amount equal to 100% of the Net Cash Proceeds of any sale, assignment, transfer, conveyance, lease or other disposition of Property by any Credit Party (including of any Capital Stock of any Person, including a Credit Party, except to the extent that such Credit Party is issuing or selling its own Capital Stock; it being understood that such is covered in clause (iii)) to the extent that such Net Cash Proceeds are not reinvested within 180 days of receipt thereof in Property related to the Business, such prepayment to be made no later than the first Payment Date for LIBOR Loans (or, if no LIBOR Loans are outstanding, then the first Payment Date for Base Rate Loans) that occurs on or after the date that is the earlier of: (A) 180 days after the receipt by any Credit Party of such Net Cash Proceeds and (B) the decision of the applicable Credit Party not to so reinvest such proceeds.

(ii) New Debt. The Borrower shall prepay the outstanding Loans in an aggregate principal amount equal to 100% of the Net Cash Proceeds of the issuance after the Closing Date by any of the Credit Parties of any Indebtedness of the types described in clauses (a) and (b) of the definition of “Indebtedness” (other than under the VAT Facility), such prepayment to be made promptly (and, in any event, within one Business Day) after any Credit Party’s receipt of such Net Cash Proceeds,

(iii) Equity Proceeds. Other than with respect to sales by a Credit Party of Capital Stock issued by a different Person (which is covered in clause (i)), the Borrower shall prepay the outstanding Loans in an aggregate principal amount equal to 100% of the Net Cash Proceeds of any issuance or sale of Capital Stock by any Credit Party, such prepayment to be made promptly (and, in any event, within one Business Day) after any Credit Party’s receipt of such Net Cash Proceeds; provided that such shall not apply to: (A) issuances and sales of Capital Stock by one Credit Party to another Credit Party and (B) the sale by the Borrower of Capital Stock to Citigroup in connection with the Acquisition.

Bredie Credit Agreement 24

together with: (A) all accrued interest, fees and other amounts payable to any of the Financing Parties under the Financing Documents (including any amounts required pursuant to Section 3.4) plus (B) a premium equal to 1% of the outstanding principal amount of the Loans, which premium shall be allocated to each Lender in accordance with its Pro Rata Share.

(v) Application. Each prepayment of Loans made pursuant to this clause (b) shall be applied to the Loans of each Lender in accordance with such Lender’s Pro Rata Share.

SECTION 2.5 Repayment. The Borrower shall repay the principal of all Loans in full, plus all accrued and unpaid interest thereon, on the Maturity Date. Except to the extent otherwise specifically provided in the Financing Documents, all other Obligations shall be paid on the Maturity Date.

SECTION 2.6 Interest. (a) Each Loan shall bear interest on the outstanding principal amount thereof from the Closing Date at a rate per annum equal to: (i) LIBOR (Reserve Adjusted) plus the Applicable Margin or (ii) the Base Rate plus the Applicable Base Rate Margin, as selected by the Borrower.

(b) Interest on each Loan shall be paid in arrears on each Payment Date. Accrued interest also shall be paid on the date of any prepayment of Loans under Section 2.4 for the portion of the Loans so prepaid.

(c) Notwithstanding clauses (a) and (b), while any Default exists: (i) the Borrower shall pay interest (after as well as before entry of judgment thereon to the extent permitted by Applicable Law) on the principal amount of all outstanding Loans and, to the extent permitted by Applicable Law, on any other due but unpaid Obligations, at a rate per annum equal to the applicable Default Rate, and (ii) all such interest shall be payable on demand of the Administrative Agent (with respect to interest on the Loans) or the Person to whom such payment is due.

(d) Anything herein to the contrary notwithstanding, the Obligations shall be subject to the limitation that payments of interest shall not be required for any period for which interest is computed hereunder to the extent (but only to the extent) that contracting for or receiving such payment by such Lender would be contrary to any law applicable to such Lender that limits the highest rate of interest that lawfully may be contracted for, charged or received by such Lender, and in such event the Credit Parties shall pay such Lender interest at the highest rate permitted by Applicable Law.

(e) With respect to any Interest Period of shorter duration than three months pursuant to the definition of “Interest Period,” the Borrower shall notify the Administrative Agent, which notice must be received by the Administrative Agent not later than 11:00 a.m. (New York City time) at least three Business Days before the commencement of such Interest Period, of the desired duration of such Interest Period.

(f) The Administrative Agent promptly (and, in any event, on the day such notice is received) shall notify each Lender of its receipt of each notice pursuant to clause (e).

Bredie Credit Agreement 25

(g) The Borrower may, upon irrevocable written notice given to the Administrative Agent not later than 11:00 a.m. (New York City time) on the third Business Day before the date of the proposed conversion, convert all outstanding Loans from LIBOR Loans into Base Rate Loans or from Base Rate Loans into LIBOR Loans; provided that any conversion of a LIBOR Loan into a Base Rate Loan only shall be made on the last day of the Interest Period for such LIBOR Loan. Such notice shall specify the date of such conversion (which shall be a Business Day). The Administrative Agent promptly shall notify each Lender of its receipt of each such notice.

SECTION 2.7 Fees. The Borrower shall pay to the Administrative Agent, for its own account, the fees set forth in the separate fee letter(s) between the Borrower and the Administrative Agent pursuant to the terms thereof.

SECTION 2.8 Computation of Fees and Interest. (a) All computations of interest for Base Rate Loans shall be made on the basis of the actual number of days in the applicable year and actual days elapsed. All other computations of interest and fees shall be made on the basis of a 360-day year and actual days elapsed. Interest and fees shall accrue during each period during which such interest or fees are computed from the first day thereof to the last day thereof.

(b) Each determination of an interest rate (and the related amount of interest payable on the Loans) by the Administrative Agent shall be conclusive and binding upon the Credit Parties and the Lenders in the absence of manifest error. The Administrative Agent shall, at the written request of the Borrower or any Lender, deliver to the Borrower or such Lender, as the case may be, a written statement showing the quotations used by the Administrative Agent in determining any interest rate and the resulting interest rate.

SECTION 2.9 Payments by Credit Parties. (a) All payments to be made by any Credit Party under the Financing Documents shall be made without set-off, defense, recoupment or counterclaim or other reduction. Except as otherwise expressly provided herein, all payments by (or on behalf of) any Credit Party under the Financing Documents shall be made to the Administrative Agent for the account of the Lenders (or other applicable recipient) at the Payment Office, and shall be made in Dollars, and in immediately available funds, no later than 12:00 noon (New York City time) on the specified payment date. The Administrative Agent promptly (and, in any event, on the date received) shall distribute to each Lender (or other applicable recipient) its Pro Rata Share (or other applicable share as expressly provided in the Financing Documents) of such payment in like funds as received. Any payment received by the Administrative Agent later than 12:00 noon (New York City time) on a payment date shall be deemed to have been received on the following Business Day, and any applicable interest or fee shall continue to accrue; provided that such shall not be considered to be a Default and no Default Rate shall be applicable as a result thereof.

(b) Whenever any payment is due on a day other than a Business Day, such payment shall be made on the preceding Business Day, and such reduction of time shall in such event be included in the computation of interest or fees, as the case may be.

Bredie Credit Agreement 26

(c) Unless the Administrative Agent receives notice from the Borrower before the date on which any payment is due to the Lenders that the Borrower (or the Guarantors on its behalf) shall not make such payment in full as and when required, the Administrative Agent may assume that the Credit Parties have made such payment in full to the Administrative Agent on such date in immediately available funds and the Administrative Agent may (but shall not be so required), in reliance upon such assumption, distribute to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Credit Parties have not made such payment in full to the Administrative Agent, then each Lender shall repay to the Administrative Agent on demand such amount so distributed to such Lender by the Administrative Agent, together with interest thereon at the Federal Funds Rate for each day from the date such amount is distributed to such Lender to the date repaid to the Administrative Agent. The giving of notice by the Borrower to the Administrative Agent that the Borrower shall not make (or cause the Guarantors to make) any payment in full as and when required shall not be construed in any manner whatsoever as: (x) a consent by the Financing Parties to such failure to pay or (y) a waiver to any of the rights that the Financing Parties may have.

(d) Payments received by the Administrative Agent from (or on behalf of) the Borrower in respect of Loans shall be applied as follows: first, to any fees (on a pro rata basis) due pursuant to Section 2.7; second, to any interest (including, if applicable, at the Default Rate) due and payable pursuant to Section 2.6 (including, pursuant to Section 2.6(b), on any amount of the Loans that is prepaid), such interest to be paid pro rata to each Lender; third, to principal due and payable pursuant to Sections 2.4 and 2.5, such principal to be paid pro rata to each Lender; and fourth, to all other Obligations payable in connection with the Financing Documents in such order as shall be determined by the Required Lenders; it being understood that the Payment Dates for interest for the Loans may not be concurrent and any payment of interest with respect to a Loan shall be applied only to interest then due and payable on the Loans.

SECTION 2.10 [RESERVED]

SECTION 2.11 Sharing of Payments, Etc. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Loans held by it any payment (whether voluntary, involuntary, through the exercise of any right of set-off or otherwise) in excess of its Pro Rata Share (or other share contemplated hereunder), then such Lender shall promptly: (a) notify the Administrative Agent of such fact and (b) purchase from the other Lenders such participations in the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment pro rata with each of the other Lenders in accordance with such Lender’s Pro Rata Share; provided that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, then 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 ratable share (according to the proportion of: (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Credit Parties agree that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by Applicable Law, exercise all its rights to receive payment (including the right of set-off, but subject to Section 10.9) with respect

Bredie Credit Agreement 27

to such participation as fully as if such Lender were the direct creditor of the Credit Parties in the amount of such participation and not subject to the restrictions on Participant voting rights under Section 10.8(c). The Administrative Agent shall keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and in each case shall notify the Lenders following any such purchases or repayments.

ARTICLE III

TAXES AND ILLEGALITY

SECTION 3.1 Taxes. (a) Any and all payments by the Credit Parties to the Financing Parties under the Financing Documents shall be made free and clear of and without deduction or withholding for any and all present and future Taxes, excluding: (i) in the case of each such Financing Party, taxes imposed upon or measured by its net income or net profits and franchise or similar taxes and branch profits or similar taxes imposed upon it, by any jurisdiction as a result of any current or former connection between such Financing Party and such jurisdiction or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Financing Party having executed, delivered or performed its obligations or received a payment under, or having been a party to, or having enforced this Agreement or any other Financing Document) and (ii) taxes imposed by any jurisdiction outside México other than any taxes that arise as a result of any Credit Party causing payment to be made from or through a jurisdiction other than México (all such excluded Taxes are herein referred to as “Excluded Taxes” and all Taxes that are not Excluded Taxes are herein referred to as “Covered Taxes”).

(b) If any Credit Party shall be required by Applicable Law to deduct or withhold any Covered Taxes from or in respect of any sum payable under any Financing Document to any Financing Party, then:

(i) the sum payable shall be increased by such additional amounts (the “Additional Amounts”) as necessary so that, after making all required deductions and withholdings of Covered Taxes, such Financing Party receives an amount equal to the sum it would have received had no such deductions or withholdings of Covered Taxes been made,

(ii) such Credit Party shall make such deductions and withholdings, and

(iii) such Credit Party promptly shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with Applicable Law;

provided that notwithstanding any contrary provisions and excluding any Person organized under the laws of México and any Export Credit Agency from the applicability of this proviso, the Credit Parties shall not be obligated to pay to any Financing Party any amounts described in this Section 3.1 in respect of any portion of Covered Taxes (including any Additional Amounts) that would not have been imposed but for the failure of such Financing Party: (A) to be registered with Hacienda as a Foreign Financial Institution, or (B) to be a resident (or to have the principal offices of such Financing Party be a resident, if such Financing Party lends through a branch or

Bredie Credit Agreement 28

agency) for tax purposes, of a country with which México has entered into a treaty that is in effect for the avoidance of double taxation, entitled to the benefits of such treaty and to the reduced rate established in such treaty for the type of interest provided therein, or (C) to comply with any certification, identification, information, declaration or other reporting requirements or to deliver to the Credit Parties information, documentation or other evidence concerning the nationality, residence, identity or registration with Hacienda of such Financing Party, in each case if compliance is required by a statute, treaty or regulation of México or any political subdivision thereof or any taxing authority therein or general administrative practice of a Mexican Governmental Authority as a precondition or requirement to the exemption from, or the reduction in the rate of, deduction or withholding of Taxes; provided that any such Financing Party may cure any such failure in order to receive such Additional Amounts if such cure is sufficiently timely to effect or obtain the exemption from or reduction in the rate of deduction or withholding of Taxes.

(c) Each Financing Party (other than a Person that is organized under the laws of México or an Export Credit Agency) represents and warrants to the Credit Parties that such Financing Party is registered as a Foreign Financial Institution with Hacienda and resident of a country that is a party to a treaty with México for the avoidance of double taxation entitled to the benefits of such treaty and to the reduced rate established in such treaty for the type of interest provided therein.

(d) Each Credit Party agrees to indemnify and hold harmless each Financing Party for any Covered Taxes and Other Taxes paid by such Financing Party in connection with the execution, delivery and performance of this Agreement, including penalties and interest arising therefrom or with respect thereto, whether or not such Covered Taxes and Other Taxes were correctly or legally asserted. Payment under this indemnification shall be made within 30 days after the date on which such Financing Party makes written demand therefor.

(e) Within 30 days after the date of any payment by any Credit Party of any Covered Taxes in connection with any payment by any Credit Party under the Financing Documents, such Credit Party shall furnish to the Administrative Agent (for distribution to the applicable Financing Party(ies)) the original or a certified copy of a receipt evidencing payment thereof, or other evidence of payment reasonably satisfactory to the Administrative Agent.

(f) Each Financing Party (other than any Person organized under the laws of México or an Export Credit Agency) shall use reasonable efforts (consistent with legal and regulatory restrictions): (i) to file any certificate or document or to furnish any information as reasonably requested by a Credit Party pursuant to any applicable treaty, law or regulation or (ii) to designate a different Lending Office, if the making of such a filing, the furnishing of such information or the designation of such other Lending Office would avoid the need for or reduce the amount of any Additional Amounts payable by the Credit Parties pursuant to this Section and would not, in the sole judgment of such Financing Party, be illegal or otherwise disadvantageous to such Financing Party. It is understood and agreed that nothing in this Section shall interfere with the rights of any Financing Party to conduct its fiscal and tax affairs in such manner as it deems fit.

Bredie Credit Agreement 29

(g) (i) If any additional amounts or indemnity payments are made by the Credit Parties to any Financing Party with respect to any Covered Taxes or Other Taxes pursuant to this Section 3.1 and such Financing Party in its reasonable discretion is entitled to a refund of such Covered Taxes or Other Taxes from the taxing jurisdiction to which the Covered Taxes or Other Taxes were paid, then such Financing Party shall, to the extent that it can do it so without prejudice to the retention of the amount of such refund, make reasonable efforts that would not materially prejudice such Financing Party or otherwise be detrimental to such Financing Party to apply for such refund and reimburse to the Credit Parties such amount of any refund received (net out-of-pocket expenses incurred).

(ii) If any payment is made by the Credit Parties to or for the account of any Financing Party after deduction for or on account of any Covered Taxes or Other Taxes, and increased payments are made by the Credit Parties pursuant to this Section 3.1, then, if such Financing Party at its reasonable discretion determines that it has received or been granted a refund or credit for such Covered Taxes or Other Taxes, such Financing Party shall, to the extent that it can do so without prejudice to the retention of the amount of such refund or credit, reimburse to the Credit Parties such amount as such Financing Party shall determine in its reasonable discretion to be attributable to the relevant Covered Taxes, Other Taxes, or deduction, or withholding. Nothing herein contained shall oblige any Financing Party to disclose its tax returns or any other information it deems confidential taking into account the other provisions of this Section 3.1(g).

(h) The Credit Parties shall be responsible for the payment of any and all Other Taxes and any interest and penalties related thereto.

SECTION 3.2 Illegality. (a) If, on or after the Closing Date, any Lender determines that the introduction of any Applicable Law, any change in any Applicable Law or in the interpretation or administration of any Applicable Law, or any other reason whatsoever has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make or maintain LIBOR Loans, then, on written notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to continue (or convert Base Rate Loans into) LIBOR Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower in writing that the circumstances giving rise to such determination no longer exist.

(b) If a Lender determines that it is unlawful to maintain any outstanding LIBOR Loan, then the Borrower shall, upon its receipt of written notice of such fact and demand from such Lender (with a copy to the Administrative Agent), prepay in full any LIBOR Loan of such Lender then outstanding, together with interest accrued thereon, either on the last day of the Interest Period thereof or, if earlier, on the date on which such Lender may no longer lawfully continue to maintain such LIBOR Loan. If the Borrower is required so to prepay any LIBOR Loan, then, concurrently with such prepayment, the Borrower shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan having the same principal amount; it being understood that any such repayment by the Borrower shall not constitute a repayment of the Loan hereunder pursuant to Section 2.5.

Bredie Credit Agreement 30

(c) If the obligation of any Lender to continue (or convert Base Rate Loans into) LIBOR Loans has been so terminated or suspended, then all Loans that otherwise would be continued (or converted) by such Lender as LIBOR Loans shall be maintained as Base Rate Loans instead.

(d) Before giving any notice to the Administrative Agent or demand upon the Borrower under this Section, an affected Lender shall designate a different Lending Office with respect to its LIBOR Loans if such designation shall avoid the need for giving such notice or making such demand and shall not, in the sole judgment of such Lender, be illegal or otherwise disadvantageous to such Lender.

SECTION 3.3 Increased Costs and Reduction of Return. (a) If any Lender determines that, due to either: (i) the introduction of or any change in or in the interpretation of any Applicable Law or (ii) the compliance by such Lender with any guideline or request from any Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining any Loan, then the Borrower shall be liable for, and from time to time, promptly upon demand (with a copy of such demand to be sent to the Administrative Agent), shall pay to the Administrative Agent for the account of such Lender, additional amounts as are sufficient to compensate such Lender for such increased costs (calculated in accordance with Section 3.4). For the avoidance of doubt, this Section 3.3 does not apply to Taxes which are covered solely by Section 3.1.

(b) If any Lender shall determine that: (i) the introduction of any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation, (iii) any change in the interpretation or administration of any Capital Adequacy Regulation by any Governmental Authority charged with the interpretation or administration thereof or (iv) compliance by such Lender (or its Lending Office) or any Person controlling such Lender with any Capital Adequacy Regulation, affects or would affect the amount of capital required or expected to be maintained by such Lender, its Lending Office or such Person and (taking into consideration such Lender’s, such Lending Office’s or such Person’s policies with respect to capital adequacy and such Lender’s or such Person’s desired return on capital) determines that the amount of such capital is increased as a consequence of its Commitment, Loans, credits or obligations under this Agreement, then, upon written demand of such Lender to the Borrower through the Administrative Agent, the Borrower promptly shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by the Lender, additional amounts sufficient to compensate such Lender for such increase.

SECTION 3.4 Funding Losses. Within fifteen days after demand, the Borrower shall reimburse each Lender and hold each Lender harmless from any loss or expense that such Lender has sustained or incurred as a consequence of:

(a) the failure of the Borrower to make on a timely basis any payment of principal or interest of any LIBOR Loan,

(b) the failure of the Borrower to borrow a Loan on the Closing Date,

Bredie Credit Agreement 31

(d) the prepayment or other payment (including after acceleration thereof for any reason) of a LIBOR Loan on a day that is not the last day of the relevant Interest Period, in each case other than a prepayment required pursuant to Section 3.2(b),

including any such loss or expense arising from the liquidation or reemployment of funds obtained by such Lender to maintain its LIBOR Loans (but excluding loss of the Applicable Margin for the period after any such payment or failure to borrow or prepay), or from fees payable to terminate the deposits from which such funds were obtained. For purposes of calculating amounts payable by the Borrower to the Lenders under this Section and under Section 3.3(a), each LIBOR Loan made by a Lender (and each related reserve, special deposit or similar requirement) conclusively shall be deemed to have been funded at LIBOR (Reserve Adjusted) applicable to such Loan by a matching deposit or other borrowing for a comparable amount and for a comparable period, whether or not such Loan is in fact so funded.

SECTION 3.5 Inability to Determine Rates. (a) If the Administrative Agent determines that for any reason adequate and reasonable means do not exist for determining LIBOR for any Interest Period with respect to a proposed LIBOR Loan, then the Administrative Agent promptly shall so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain LIBOR Loans hereunder shall be suspended until the Administrative Agent revokes such notice in writing, which revocation shall be promptly given upon such adequate and reasonable means of determining LIBOR becoming available. If LIBOR Loans are then outstanding, then such Lenders shall continue such Loans as Base Rate Loans during each following Interest Period for such Loan until the Administrative Agent revokes such notice in writing.

(b) If any Lender determines that LIBOR applicable to any Interest Period with respect to a LIBOR Loan would not adequately and fairly reflect the cost to such Lender of funding such LIBOR Loan, then such Lender promptly so shall notify the Administrative Agent and the Borrower. Thereafter, the obligation of such Lender (but not the other Lenders) to make or maintain LIBOR Loans hereunder shall be suspended until such Lender revokes such notice in writing, which revocation shall be promptly given as soon as such Lender determines that the applicable LIBOR would adequately and fairly reflect its cost of funding such LIBOR Loan. If LIBOR Loans are then outstanding, then such Lender shall continue such Loans as Base Rate Loans during each following Interest Period for such Loan until such Lender revokes such notice in writing.

SECTION 3.6 Certificates of the Lenders and Administrative Agent. Any Lender or Agent claiming reimbursement or compensation under this Article shall deliver to the Borrower (with a copy to the Administrative Agent) a certificate setting forth in reasonable detail the reason for such reimbursement or compensation and the amount payable to such Lender or the Administrative Agent hereunder, which certificate shall constitute prima facie evidence of the accuracy of the information so detailed.

Bredie Credit Agreement 32

SECTION 3.7 Substitution of Lenders. If any Lender (an “Affected Lender”) fails to meet the status referenced in Section 3.1(b) or is entitled to additional amounts or indemnity payments under Section 3.3 of this Agreement, the Borrower may: (i) request the Affected Lender to use reasonable efforts to obtain a replacement bank or financial institution satisfactory to the Borrower (a “Replacement Lender”) to acquire and assume all or a portion of all of such Affected Lender’s Loans and Commitment, (ii) request one or more of the other Lenders to acquire and assume all or part of such Affected Lender’s Loans and Commitment; it being understood that no such other Lender shall be so required to acquire and assume any of such Loans and/or Commitments, or (iii) designate a Replacement Lender. Any designation of a Replacement Lender under clause (i) or (iii) shall be subject to the prior written consent of the Administrative Agent (which consent shall not be unreasonably withheld or delayed and shall be deemed to have been given if no negative response shall have been received from the Administrative Agent within five Business Days of the Administrative Agent’s receipt of a request for such consent) and the other provisions relating to the assignment set forth in Section 10.8.

SECTION 3.8 Survival. With the exception of the obligations of the Credit Parties under Section 3.1 (which obligations shall survive indefinitely), the agreements and obligations of the Credit Parties in this Article shall survive until the irrevocable payment in full of all Obligations in Dollars and Pesos, as applicable, and the cancellation of all the Commitments.

ARTICLE VIII

THE ADMINISTRATIVE AGENT

SECTION 8.1 Appointment and Authorization. Each Lender hereby irrevocably (subject to Section 8.9) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the Financing Documents and to exercise such powers and perform such

Bredie Credit Agreement 62

duties as expressly are delegated to it by the Financing Documents, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained in any Financing Document: (a) the Administrative Agent shall not have any duties or responsibilities except those expressly set forth therein, (b) the Administrative Agent shall not have or be deemed to have any fiduciary relationship with any other Financing Party, (c) no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into any Financing Document or otherwise exist against the Administrative Agent and (d) the Administrative Agent shall not be required to take any action that is contrary to any Applicable Law. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Agreement or any other Financing Document with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties.

SECTION 8.2 Delegation of Duties. The Administrative Agent may execute any of its respective duties under any Financing Document by or through agents, employees or attorneys-in-fact, and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for any degree of negligence or misconduct of any agent or attorney-in-fact that the Administrative Agent selects with reasonable care.

SECTION 8.3 No Liability of Agent-Related Persons. None of the Agent-Related Persons shall: (a) be liable for any action taken or omitted to be taken by any of them under or in connection with any Financing Document or the transactions contemplated thereby (except for such Person’s own gross negligence, bad faith, willful misconduct or breach of such Financing Agreement) or (b) be responsible in any manner to any of the Financing Parties or Credit Parties for: (i) any recital, statement, representation or warranty made by any of the Credit Parties or Credit Party Affiliates, or any officer thereof, contained in any Financing Document or in any certificate, report, statement or other document referred to or provided for in, or received by any Agent-Related Person under or in connection with, any Financing Document, (ii) the validity, effectiveness, genuineness, enforceability or sufficiency of any Financing Document (except as to such Agent-Related Person’s execution thereof) or (iii) any failure of any of the Credit Parties or any other party to any Financing Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Financing Party or Credit Party to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, any Financing Document, or to inspect the Properties, books or records of any of the Credit Parties or Credit Party Affiliates.

SECTION 8.4 Reliance by the Agent-Related Persons. Each Agent-Related Person shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, facsimile or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person(s), and upon advice and statements of legal counsel (including counsel to any of the Credit Parties), independent accountants and other experts selected by any Agent-Related Person. Each Agent-Related Person shall be fully justified in failing or refusing to take any action under any Financing Document unless it shall first receive such advice or concurrence of

Bredie Credit Agreement 63

the Required Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. Each Agent-Related Person in all cases shall be fully protected in acting, or in refraining from acting, under any Financing Document in accordance with a request or consent of the Required Lenders and such request and any action taken or failure to act under any Financing Document pursuant thereto shall be binding upon all of the Financing Parties.

SECTION 8.5 Notice of Default. (a) No Agent-Related Person shall be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default (except the Administrative Agent with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the applicable Lenders and/or the Administrative Agent) unless such Agent-Related Person shall have received written notice from a Financing Party or any of the Credit Parties referring to this Agreement, describing such Default or Unmatured Default and stating that such notice is a “notice of default” or similar statement. Such Agent-Related Person promptly shall notify each Lender of its receipt of any such notice and (in the case of the Administrative Agent) of the occurrence of any default in the payment of principal, interest or fees required to be paid to the Administrative Agent for the account of the applicable Lenders and/or the Administrative Agent. The Administrative Agent shall take such action with respect to such Default or Unmatured Default as may be requested by the Required Lenders in accordance with Article VII; provided that unless and until the Administrative Agent has received any such request and so notified the Lenders, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Unmatured Default as it shall deem advisable or in the best interest of the Financing Parties.

(b) Notwithstanding clause (a), each Agent-Related Person and each Lender shall use its best efforts to notify each Agent upon obtaining knowledge of any Default or Unmatured Default.

SECTION 8.6 Credit Decision. Each Lender acknowledges that none of the Agent-Related Persons has made any representation or warranty to it, and that no act by any Agent-Related Person hereinafter taken, including any review of the affairs of the Credit Parties and the Credit Party Affiliates, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender or other Agent-Related Person. Each Lender represents to the Administrative Agent and the Lead Arranger that it has, independently and without reliance upon any Agent-Related Person and based upon such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, Property, financial and other condition and creditworthiness of the Credit Parties, and all applicable bank regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into the Financing Documents to which it is a party and to extend credit to the Borrower thereunder. Each Lender also represents that it shall, independently and without reliance upon any Agent-Related Person and based upon such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under the Financing Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, Property, financial and other condition and creditworthiness of the Credit Parties. Except for

Bredie Credit Agreement 64

notices, reports and other documents expressly herein or in the other Financing Documents required to be furnished to the Lenders by the Administrative Agent, no Agent-Related Person shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, Property, financial and other condition or creditworthiness of the Credit Parties that may come into the possession of any of the Agent-Related Persons.

SECTION 8.7 Indemnification of Agent-Related Persons. Whether or not the transactions contemplated hereby are consummated, each Lender agrees to indemnify upon demand the Agent-Related Persons (to the extent not reimbursed by or on behalf of the Credit Parties and without limiting the obligation of the Credit Parties to do so), on the basis of such Lender’s ratable share from and against any and all Indemnified Liabilities; provided that no Lender shall be liable for the payment to any Agent-Related Person of any portion of the Indemnified Liabilities to the extent a court of proper jurisdiction has delivered a final determination that such Indemnified Liabilities resulted from such Agent-Related Person’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender shall reimburse each Agent-Related Person upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by such Agent-Related Person in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, any Financing Document or any document contemplated by or referred to therein to the extent that such Agent-Related Person is not reimbursed for such expenses by or on behalf of the Credit Parties. A Lender’s ratable share with respect to the Administrative Agent or the Lead Arranger or any Agent-Related Person related to the Administrative Agent or the Lead Arranger shall be such Lender’s Pro Rata Share. The undertaking in this Section shall survive the payment of all Obligations hereunder, the cancellation of all the Commitments and, as to any Agent-Related Person, the resignation or replacement of such Agent-Related Person.

SECTION 8.8 The Agent-Related Persons in Their Individual Capacity. Each Agent-Related Person may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Credit Parties and their Affiliates as though the Administrative Agent did not act in such capacity under the Financing Documents, without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, the Agent-Related Persons may receive information regarding the Credit Parties or their Affiliates (including information that may be subject to confidentiality obligations in favor of such Person) and acknowledge that no Agent-Related Person shall be under any obligation to provide such information to any Lender. With respect to its Loans, each Lender that also acts as the Administrative Agent under the Financing Documents shall have the same rights and powers under the Financing Documents as any other Lender and may exercise the same as though it were not the Administrative Agent thereunder.

SECTION 8.9 Successor Administrative Agent.

(a) The Administrative Agent may, and at the request of the Required Lenders shall, resign as the Administrative Agent upon at least 30 days’ prior written notice to the Lenders. If

Bredie Credit Agreement 65

the Administrative Agent resigns under this Agreement, then the Required Lenders shall appoint from among the Lenders a successor agent who, unless a Default then exists, shall be reasonably acceptable to the Borrower. If no such successor agent is appointed before the date on which a retiring Administrative Agent’s resignation is to become effective in accordance with its notice of resignation, then such Administrative Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders who, unless a Default then exists, shall be reasonably acceptable to the Borrower. Upon the acceptance of its appointment as successor agent hereunder: (i) such successor agent shall succeed to all the rights (including as to the same fees), powers and duties of such retiring Administrative Agent, (ii) the term “Administrative Agent” shall mean such successor agent and (iii) such retiring Administrative Agent’s appointment, powers and duties as such Administrative Agent shall be terminated. After any such retiring Administrative Agent’s resignation hereunder, this Article and Sections 10.4 and 10.5 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was such Administrative Agent under the Financing Documents.

(b) Any Person: (i) into which the Administrative Agent may be merged or consolidated, (ii) that may result from any merger, conversion or consolidation to which an Administrative Agent shall be a party or (iii) that may succeed to all or substantially all of the corporate trust business of the Administrative Agent shall be the successor of the Administrative Agent without the execution or filing of any instrument or any further act on the part of any of the parties hereto.

ARTICLE IX

GUARANTY

SECTION 9.1 Guaranty. (a) For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby, jointly and severally, as primary obligor and not merely as surety, unconditionally guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the payment Obligations (howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due) under the Financing Documents. Upon the failure by the Borrower to pay punctually any of its Obligations, the Guarantors (jointly and severally) shall immediately pay the amount not so paid. The obligations of the Guarantors under this Article shall constitute a guaranty of payment and not merely a guaranty of collection.

(b) All payments by any Guarantor under this Article shall be payable in the manner required for payments by the Borrower hereunder, including: (i) the obligation to make all such payments free and clear of, and without deduction for, any Covered Taxes (including withholding taxes) in the manner provided in Section 3.1 and (ii) the obligation to pay interest at the Default Rate.

SECTION 9.2 Guaranty Unconditional. The obligations of the Guarantors under this Article shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by any reason, including:

Bredie Credit Agreement 66

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any Obligation(s) and/or any Commitment(s) under the Financing Documents, by operation of law or otherwise,

(b) any modification or amendment of or supplement to this Agreement or any other Financing Document,

(c) any change in the existence, structure or ownership of the Borrower or any other Credit Party, or any event described in Section 7.1(i) with respect to any Person,

(d) the existence of any claim, set-off or other rights that a Guarantor may have at any time against the Borrower, any other Credit Party, the Administrative Agent, any other Financing Party or any other Person, whether in connection herewith or any unrelated transactions,

(e) any invalidity, irregularity or unenforceability relating to or against the Borrower or any other Credit Party for any reason of any Financing Document, or any provision of Applicable Law purporting to prohibit the payment by the Borrower or any other Credit Party of any of the Obligations, or

(f) any other act or omission to act or delay of any kind by the Borrower and/or any other Credit Party, the Administrative Agent, any other Financing Party or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of (or defense against) the Obligations and the Guarantors’ obligations under this Article other than prior payment of the Obligations.

SECTION 9.3 Discharge only upon Payment in Full; Reinstatement in Certain Circumstances. The Guarantors’ obligations hereunder shall remain in full force and effect until all of the payment Obligations shall have been paid in full and all of the Commitments shall have terminated. If at any time any payment made under this Agreement or any other Financing Document is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy or reorganization of a Credit Party or any other Person or otherwise, then the Guarantors’ obligations 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 Guarantor hereby irrevocably and unconditionally waives, to the fullest extent permitted by Applicable Law: (i) notice of acceptance of the guaranty provided in this Article and notice of any liability to which this guaranty may apply, (ii) all notices that may be required by Applicable Law or otherwise to preserve intact any rights of any Financing Party against the Borrower and/or any other Credit Party, including any demand, presentment, protest, proof of notice of non-payment, notice of any failure on the part of the Borrower and/or any other Credit 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 the Borrower, any other Credit Party and any other guarantor thereof from time to time) except any of the foregoing as may be expressly required hereunder, (iii) any right to the enforcement,

Bredie Credit Agreement 67

assertion or exercise by any Financing Party of any right, power, privilege or remedy conferred upon such Person under the Financing Documents or otherwise, (iv) any requirement that any Financing Party exhaust any right, power, privilege or remedy, or mitigate any damages resulting from a default, under any Financing Document, or proceed to take any action against a Credit Party or any other Person under or in respect of any Financing Document or otherwise, or protect, secure, perfect or ensure any Lien on any collateral, and (v) the benefit of any statute of limitations affecting the Guarantors’ or any other Credit Party’s liability in respect of any of the payment Obligations, and each Guarantor agrees that any payment of any Obligation to the applicable Person and any other act that shall toll any statute of limitations applicable to the Obligations shall also operate to toll such statute of limitations applicable to such Guarantor’s liability under this Article.

(b) Each Guarantor hereby further waives any right to which it may be entitled under Articles 2836, 2846, 2848 and 2849 of the Federal Civil Code (Código Civil Federal) of México and similar articles contained in the Civil Codes of the States of México and the Federal District. Each Guarantor further expressly waives the benefits of order, excusión and división contained in Articles 2814, 2815, 2817, 2818, 2820, 2821, 2822, 2823, 2839, 2840, 2841 and other similar articles of the Federal Civil Code of México and similar articles contained in the Civil Codes of the States of México and the Federal District.

SECTION 9.5 Subrogation. Upon a Guarantor’s making payment with respect to any obligation under this Article, such Guarantor shall be subrogated to the rights of the payee against the Borrower (or the other obligor) with respect to such obligation; provided that such Guarantor shall not be a Financing Party and shall not enforce any payment by way of subrogation, indemnity or otherwise, or exercise any other right, against the Borrower (or such other obligor) so long as any Obligations (other than on-going but not yet incurred indemnity obligations) remain unpaid and/or any Commitments remain outstanding.

SECTION 9.6 Stay of Acceleration. If acceleration of the time for payment of any Obligations is stayed due to any event described in Section 7.1(i), then all such amounts otherwise subject to acceleration under this Agreement shall nonetheless be payable by the Guarantors hereunder.

ARTICLE X

(c) Any agreement of the Financing Parties herein to receive certain notices by telephone or facsimile or other electronic transmission is solely for the convenience and at the request of the Credit Parties. The Financing Parties shall be entitled to rely upon the authority of any Person purporting to be a Person authorized by a Credit Party to give such notice and the Financing Parties shall not have any liability to any Credit Party or any other Person on account of any action taken or not taken by the Financing Parties in reliance upon such notice. The obligation of the Credit Parties to repay the Obligations shall not be affected in any way or to any extent by any failure by the Financing Parties to receive written confirmation of any telephonic or facsimile notice or the receipt by the Financing Parties of a confirmation that is at variance with the terms understood by the Financing Parties to be contained in the notice.

(d) Notwithstanding the foregoing: (i) a Credit Party may, at its option, provide to the Administrative Agent all information, documents and other materials that it is obligated to furnish pursuant to the Financing Documents, including all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that: (A) relates to a request for a new, or a conversion of an existing, borrowing (including any election of an interest rate or interest period relating thereto), (B) relates to the payment of any principal or other amount due under the Financing Documents before the scheduled date therefor, (C) provides notice of any Default or Unmatured Default or (D) is required to be delivered to satisfy any condition precedent to the effectiveness of the Financing Documents and/or any borrowing thereunder (all such non-excluded communications being referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium to the Administrative Agent’s e-mail address specified by the Administrative Agent by written notice to such Credit Party (with respect to Communications to the Administrative Agent), and (ii) the Administrative Agent may, at its option, make the Communications or other information available to the Lenders by posting them on Intralinks or a substantially similar electronic transmission system (the “Platform”).

(e) ANY PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT-RELATED PERSONS DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF ANY NOTICES OR OTHER COMMUNICATIONS MADE AVAILABLE BY THE ADMINISTRATIVE AGENT, OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN SUCH NOTICES AND COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT-RELATED PERSONS IN CONNECTION WITH THE PLATFORM OR THE NOTICES OR OTHER COMMUNICATIONS MADE AVAILABLE THEREBY. IN NO EVENT SHALL ANY AGENT-RELATED PERSON HAVE ANY LIABILITY TO THE CREDIT PARTIES, THE FINANCING PARTIES OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE), ARISING OUT OF THE CREDIT

Bredie Credit Agreement 70

PARTIES’ OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF NOTICES OR OTHER COMMUNICATIONS THROUGH THE PLATFORM, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT-RELATED PERSON IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH AGENT-RELATED PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

(f) The Administrative Agent agrees that the receipt of the Communications by it at its e-mail address described above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of the Financing Documents. Each Lender agrees that notice to it (as provided in the next sentence) specifying that the Communications and/or other notices have been made available to it on the Platform shall constitute effective delivery thereof to such Lender for purposes of the Financing Documents. Each Lender agrees: (i) to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

SECTION 10.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent, any Lender or any other Financing Party, any right, remedy, power or privilege under (or referred to in) any Financing Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege under any Financing Document preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

SECTION 10.4 Costs and Expense. The Borrower shall:

(a) whether or not the transactions contemplated hereby are consummated, pay or reimburse any Agent-Related Person(s), promptly upon demand by such Person, for all reasonable and reasonably documented out-of-pocket fees, costs and expenses (including Attorney Costs) incurred by or charged to any such Person in connection with the preparation, execution, delivery, negotiation and syndication of the Financing Documents,

Each Indemnified Party shall: (i) upon its becoming aware of any event that might result in the Borrower being required to perform any of its indemnity obligations hereunder, use reasonable efforts to promptly notify the Borrower (provided that failure so to notify the Borrower shall not mitigate the obligations of the Borrower hereunder), (ii) upon the Borrower’s request, consult with the Borrower regarding any step (including any step that may mitigate the effect of such event) it proposes to take in respect of such event and (iii) (unless an Unmatured Default or Default in respect of payment then exists) obtain the Borrower’s consent before entering into any settlement or compromise in relation to any such claims, actions or suits.

(b) To the extent that any undertaking in clause (a) may be unenforceable because it is violative of any Applicable Law or public policy, the Borrower shall contribute the maximum portion that it is permitted to pay and satisfy under Applicable Law to the payment and satisfaction of such undertaking.

(c) All such amounts and costs payable or indemnified under this Section shall be included in the Obligations and shall be immediately due and payable on demand.

(d) The Borrower’s obligations hereunder and under Sections 3.1 and 10.4 shall survive the execution and delivery of the Financing Documents, the making and repayment of the Loans and (with respect to any applicable Indemnified Person) its resignation and/or removal.

(e) To the fullest extent permitted by Applicable Law, each Credit Party agrees that it shall not assert, and hereby waives, any claim against any Indemnified Party on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Financing Document or any agreement or document contemplated hereby, the transactions contemplated hereby or thereby, any Loan and/or the use of the proceeds thereof.

Bredie Credit Agreement 72

SECTION 10.6 Payments Set Aside. If any Credit Party (or any Person on its behalf) makes a payment to any Financing Party, or any Financing Party exercises its right of set-off, and such payment or the proceeds of such set-off or any part thereof subsequently are invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Financing Party in its discretion) to be repaid to such Credit Party (or such Person), a trustee, síndico, receiver or any other Person in connection with any insolvency proceeding or otherwise, then: (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its Pro Rata Share of any amount so recovered from or repaid by the Administrative Agent.

SECTION 10.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective authorized successors and assigns, except that no Credit Party may assign or transfer any of its rights or obligations under this Agreement or any other Financing Document without the prior written consent of the Administrative Agent and the Required Lenders, any attempt to do so being null and void ab initio.

SECTION 10.8 Assignments, Participations, etc.

(a) Assignments. Any Lender may, with the prior written consent of the Administrative Agent and (except during the existence of a Default) the Borrower, which consent(s) shall not be unreasonably withheld or delayed, at any time assign to one or more Persons that (unless a Default exists) are Eligible Assignees (provided that no written consent of the Borrower or the Administrative Agent shall be required in connection with any assignment by a Lender to an Eligible Assignee that is a Lender or an Affiliate of any Lender and that the Borrower will be deemed to have consented to an assignment if it fails to respond negatively to a written request for consent within ten Business Days of delivery of such request and provided, further, that it is acknowledged that it is reasonable for the Borrower to withhold its consent to an assignment to a competitor of the Borrower or to an Affiliate of a competitor of the Borrower) (each an “Assignee”) all, or any portion, of the Loans, the Commitment and the other rights and obligations of such Lender hereunder, in a minimum amount (or together with concurrent assignments to affiliated Eligible Assignees in an aggregate minimum amount ) of $5,000,000 or a higher integral multiple of $1,000,000 (or, if less, all of such Lender’s remaining rights and obligations hereunder); provided that the Credit Parties and the Administrative Agent may continue to deal solely and directly with such Lender in connection with the interest so assigned to an Assignee until: (i) written notice of such assignment, together with payment instructions, addresses and related information with respect to the Assignee, shall have been given to the Borrower and the Administrative Agent by such Lender and/or its Assignee, (ii) such Lender and its Assignee shall have delivered via an electronic settlement system (or, if previously agreed with the Administrative Agent, manually) to the Administrative Agent a duly executed Assignment Agreement substantially in the form of Exhibit C (an “Assignment Agreement”) together with the Note(s) subject to such assignment and (iii) such Lender or its Assignee shall have paid to the Administrative Agent a processing and recordation fee relating to such assignment in the amount of $3,500 (which fee may be waived or reduced in the sole discretion of the Administrative Agent). Notwithstanding the foregoing, no such assignment shall be allowed if it would require securities registration under any Applicable Law or if the assigner

Bredie Credit Agreement 73

thereof (if it is assigning less than all of its Loans and Commitments) would, after such assignment, have less than $5,000,000 in Loans and remaining Commitments.

(b) Assignee as Lender. From and after the date that the Administrative Agent notifies the assignor Lender that it has received and provided its consent, and received (if such consent is applicable) the consent of the Borrower, with respect to an executed Assignment Agreement (and has received payment of the above-referenced processing fee): (i) the Assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment Agreement, shall have the rights and obligations of a Lender under the Financing Documents, and (ii) the assignor Lender shall, to the extent that rights and obligations under the Financing Documents have been assigned by it pursuant to such Assignment Agreement, be considered to have relinquished its rights and be released from its obligations under the Financing Documents.

(c) Participations. Any Lender may at any time sell to one or more financial institution(s) or other Person(s) (each a “Participant”) participating interests in any Loans, the Commitment of such Lender and the other interests of such Lender (the “originating Lender”) under the Financing Documents; provided that: (i) the originating Lender’s obligations under the Financing Documents shall remain unchanged, (ii) the originating Lender shall remain solely responsible for the performance of such obligations, (iii) the Credit Parties and the Administrative Agent shall continue to deal solely and directly with the originating Lender in connection with the originating Lender’s rights and obligations under the Financing Documents, (iv) no Lender shall transfer or grant any participating interest under which the Participant has rights to approve any amendment to, or any consent or waiver with respect to, any Financing Document, except to the extent such amendment, consent or waiver would require unanimous consent of the applicable Lenders as described in Section 10.1, and (v) if such Participant does not satisfy the definition of an Eligible Assignee, the Borrower shall be liable for Taxes and Other Taxes to such Participant (or to the originating Lender on behalf of such Participant) in an amount no greater than the amount that it otherwise would have been so liable to the originating Lender (who for purposes hereof, will have been assumed to be in compliance with Section 3.1(c)). In the case of any such participation, the Participant shall be entitled to the benefit (subject to the requirements and limitations of such Sections) of Sections 3.1 (except as set forth in clause (v) above), 3.3, 3.4 and 10.5 as though it were also a Lender hereunder, and if amounts outstanding under the Financing Documents are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of a Default, each Participant shall be deemed to have the right of set-off in respect of its participating interest in amounts owing under the Financing Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement (including such rights under Section 10.10). So long as no Default exists, an originating Lender shall provide at least ten Business Days’ prior notice to the Borrower (or such shorter notice period as the Borrower may approve) of any proposed participation to a proposed Participant that is not already a Lender, a Participant or an Affiliate of a Lender or a Participant. So long as no Default exists, such originating Lender shall not enter into such proposed participation if the Borrower provides to such originating Lender, within ten Business Days after the Borrower’s receipt of the notice of such proposed participation, notice of the Borrower’s objection to the proposed participation to such proposed Participant on the basis that such proposed Participant is a competitor or an Affiliate of a competitor of the Borrower.

Bredie Credit Agreement 74

(d) Pledge to Federal Reserve Bank. Notwithstanding any other provision in this Agreement, any Lender may (without the consent of the Borrower or the Administrative Agent or prior notice to either) at any time create a security interest in, or pledge, all or any portion of its rights under and interest in this Agreement and any Note held by it in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Board or U.S. Treasury Regulation 31 CFR §203.14, and such Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under Applicable Law; it being understood that no such security interest or pledge shall release any Lender from any of its obligations hereunder or shall substitute such Federal Reserve Bank as a party hereto.

(e) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Payment Office a copy of each Assignment Agreement 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, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

SECTION 10.9 Set-off. In addition to any rights now or hereafter granted under Applicable Law or otherwise, and not by way of limitation of any such rights, if the Loans have been accelerated, each Financing Party is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind to any Credit Party or to any other Person (any such notice being waived to the fullest extent permitted by Applicable Law), to set off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other Indebtedness at any time owing by, such Financing Party (including by branches and agencies of any Financing Party) to or for the credit or the account of a Credit Party against and on account of any and all Obligations owing to such Financing Party, now or hereafter existing, irrespective of whether or not such Financing Party shall have made demand under any Financing Document and although such Obligations may be contingent or unmatured. Each Financing Party agrees promptly to notify the applicable Credit Party and the Administrative Agent after any such set-off and application made by such Financing Party; provided that the failure to give such notice shall not affect the validity of such set-off and application.

SECTION 10.10 Notification of Addresses, Lending Offices, Etc. Each Lender shall notify the Administrative Agent in writing of any change in: (a) the address to which notices to the Administrative Agent or such Lender should be directed, (b) addresses of any Lending Office, (c) payment instructions in respect of all payments to be made to it hereunder and (d) such other administrative information as the Administrative Agent reasonably requests.

SECTION 10.11 Counterparts. This Agreement may be executed in any number of separate counterparts, each of which, when so executed, shall be deemed an original, and all of which taken together shall be deemed to constitute but one and the same instrument.

Bredie Credit Agreement 75

SECTION 10.12 Severability. The illegality or unenforceability in any jurisdiction of any provision of this Agreement or any document required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement or such other document in such jurisdiction or such provision in any other jurisdiction. With respect to any such illegal or unenforceable provision in any jurisdiction, the parties hereto agree to as promptly as possible amend this Agreement (or such other document) in such a manner as to ensure that the substance of such provision shall be replaced (at least with respect to such jurisdiction) with alternative language having substantially equivalent effect that is legal and enforceable in such jurisdiction.

SECTION 10.13 Third Party Beneficiaries. This Agreement is made and entered into for the sole protection and legal benefit of the parties hereto, the other Agent-Related Persons, the Indemnified Persons and their permitted successors and assigns (all of which, if not parties hereto, are third-party beneficiaries hereof for purposes of enforcing their respective rights hereunder), and no other Person shall be a direct or indirect legal beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF NEW YORK (NOT INCLUDING SUCH STATE’S CONFLICT OF LAWS PROVISIONS OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW); PROVIDED THAT THE FINANCING PARTIES SHALL RETAIN ALL RIGHTS ARISING UNDER U.S. FEDERAL LAW.

(b) EACH PARTY HERETO HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE U.S. DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND ANY APPELLATE COURT WITH RESPECT THERETO (COLLECTIVELY, THE “FEDERAL COURTS”) (OR, IN THE EVENT THE FEDERAL COURTS ARE UNAVAILABLE, THE SUPREME COURT OF THE STATE OF NEW YORK, COUNTY OF NEW YORK AND ANY APPELLATE COURT WITH RESPECT THERETO (SUCH COURTS, TOGETHER WITH THE FEDERAL COURTS, THE “NEW YORK COURTS”)) AND TO THE COURTS OF ITS OWN CORPORATE DOMICILE IN RESPECT OF ACTIONS BROUGHT AGAINST IT AS A DEFENDANT OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE FINANCING DOCUMENTS.

Bredie Credit Agreement 76

IS A PARTY) IN NEW YORK, NEW YORK. EACH PARTY AGREES THAT A JUDGMENT IN ANY SUCH ACTION, SUIT OR PROCEEDING MAY BE ENFORCED IN ANY OTHER APPLICABLE JURISDICTION BY SUIT UPON JUDGMENT, A CERTIFIED COPY OF WHICH SHALL BE CONCLUSIVE EVIDENCE OF THE JUDGMENT. Each of the parties hereto further agrees that service of process may be made personally or (with respect to a Credit Party) by mailing or delivering a copy of the summons and complaint or other legal process in any such legal suit, action or proceeding to a Credit Party in care of the Process Agent and such agent is hereby authorized to accept, receive and acknowledge the same for and on behalf of each Credit Party and to admit service with respect thereto. Service upon the Process Agent shall be deemed to be personal service on the applicable Credit Party and shall be legal and binding upon the applicable Credit Party for all purposes notwithstanding any failure to mail copies of such legal process to the applicable Credit Party, or any failure on the part of the applicable Credit Party to receive the same. Nothing herein shall affect the right to serve process in any other manner permitted by Applicable Law or any right to bring legal action or proceedings in any other competent jurisdiction. Each party further agrees that the aforesaid courts shall have exclusive jurisdiction with respect to any claim or counterclaim of any party based upon the assertion that the rate of interest charged by or under this Agreement or under the other Financing Documents is usurious. Each party hereby waives any right to stay or dismiss any action or proceeding under or in connection with this Agreement or any other Financing Document brought before the foregoing courts on the basis of forum non conveniens and any rights that it may be entitled to on account of place of residence or domicile. The foregoing provisions constitute, among other things, a special arrangement for service among the parties to this Agreement for the purposes of 28 U.S.C. §1608.

(c) Each Credit Party irrevocably waives, to the fullest extent permitted by Applicable Law, any claim that any action or proceeding commenced against it relating in any way to this Agreement and/or any of the other Financing Document(s) should be dismissed or stayed by reason, or pending the resolution, of any action or proceeding commenced by such Credit Party relating in any way to this Agreement and/or the other Financing Documents, whether or not commenced earlier.

SECTION 10.16 Judgment. (a) Each Credit Party’s obligations hereunder and under the other Financing Documents to make payments in Dollars shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than Dollars. If, for the purpose of obtaining or enforcing judgment against any Credit Party in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than Dollars (such other currency, the “Judgment Currency”), the conversion shall be made at the rate of exchange as quoted by the Administrative Agent or, if the Administrative Agent does not quote a rate of exchange on such currency, by a known dealer in such currency designated by the Required Lenders. Each such conversion shall be determined as of the Business Day preceding the Business Day on which the judgment is given (such preceding Business Day, the “Judgment Currency Conversion Date”).

(b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, then the Borrower covenants to pay (or cause to be paid) such additional amounts (if any) as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of Dollars that could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date.

(c) For purposes of determining the rate of exchange under this Section, such amounts shall include any premium and costs payable in connection with the purchase of the Dollars.
