CREDIT AGREEMENT (this “Agreement”), dated as of April 11, 2012 (“Signing Date”), among (i) NEXTEL TELECOMUNICAÇÕES LTDA., a limited liability company (sociedade limitada) organized and existing under the laws of Brazil (the “Borrower”), (ii) the parties listed in Annex III (the “Guarantors”) and (iii) CHINA DEVELOPMENT BANK CORPORATION as Arranger (the “Arranger”), Administrative Agent (the “Administrative Agent”) and Lender (the “Lender”).

W I T N E S S E T H:

WHEREAS, the Borrower intends to acquire equipment and related services from the Suppliers for the build-out and deployment of the telecommunications networks being deployed or to be deployed by the Borrower or its Affiliates in Brazil (the “Telecommunications Networks”), through purchases to be made pursuant to the Master Supply Agreement (the “Project”);

WHEREAS, in order to finance the acquisition of such equipment and related services from the Suppliers for the Project, the Borrower has requested the Lender to provide the credit facility described herein and the Lender is willing to provide the credit facility described herein upon the terms and conditions herein set forth;

WHEREAS, each Guarantor is a Subsidiary of the Borrower and each Guarantor acknowledges that it will, directly or indirectly, derive substantial benefit from the making of the Loans; and

NOW, THEREFORE, in consideration of the premises and mutual agreements hereinafter contained, the parties hereto agree as follows:

SECTION 1. DEFINITIONS AND RULES OF INTERPRETATION.

1.1 Defined Terms.

Except as otherwise expressly provided herein, capitalized terms used in this Agreement and its Appendices, Annexes and Exhibits shall have the respective meanings assigned to such terms in Appendix A attached hereto.

1.2 Rules of Interpretation.

Except as otherwise expressly provided herein, the rules of interpretation set forth in Appendix A hereto shall apply to this Agreement.

1.3 Accounting Principles.

Except as otherwise provided in this Agreement, all computations and determinations as to financial matters, and all financial statements to be delivered under this Agreement, shall be made or prepared in accordance with Brazilian GAAP (including principles of consolidation where appropriate) applied on a consistent basis (except to the extent approved or required by the independent public accountants certifying such statements and disclosed therein).

SECTION 2. AMOUNTS AND TERMS OF CREDIT FACILITY.

2.1 The Loans.

(a) Subject to and upon the terms and conditions set forth herein, each Lender severally agrees to make, during the Availability Period, loans (each, a “Loan” and, collectively, the “Loans”) to the Borrower, which Loans shall (i) be made and maintained in Dollars, (ii) not exceed for any Lender, in aggregate principal amount, that amount which equals the Loan Commitment of such Lender, (iii) mature on the Loan Maturity Date, and (iv)

only be applied towards the reimbursement of payments of (A) up to ninety percent (90%) of the amounts paid by the Borrower under Purchase Orders and (B) up to five percent (5%) of the amounts paid by the Borrower under the Sinosure Purchase Orders.

(b) The Loans are available only on the terms and conditions specified hereunder, and once repaid, in whole or in part, at maturity or by prepayment, may not be reborrowed in whole or in part.

2.2 Notice of Borrowing.

(a) Whenever the Borrower desires to make a Borrowing hereunder, it shall give the Administrative Agent at its Notice Office at least five (5) Business Days’ prior written notice; provided, that any such notice shall be deemed to have been given on a certain day only if given before 11:00 a.m. (Beijing time) on such day, and if any such notice is received after 11:00 a.m. (Beijing time) on a certain day, such notice shall be deemed to have been given on the following day. Each such notice (a “Notice of Borrowing”) shall be irrevocable and shall be given by the Borrower substantially in the form of Exhibit A attached hereto, appropriately completed to specify, inter alia: (i) the aggregate principal amount of the Loans to be made pursuant to such Borrowing, (ii) the proposed date of such Borrowing (which shall be a Business Day) and (iii) the account details of the Borrower, as applicable. The Administrative Agent shall promptly give each Lender at least one (1) Business Day’s prior written notice of the proposed Borrowing, of such Lender’s proportionate share thereof and of the other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing.

(b) The Borrower shall not be entitled to deliver more than one (1) Notice of Borrowing in each calendar month and each Notice of Borrowing shall only request one (1) Loan.

2.3 Pro Rata Borrowings; Availability.

(a) Each Borrowing shall be incurred ratably among the Lenders based upon the amount of each Lender’s Loan Commitment. It is agreed that no Lender shall be responsible for any default by any other Lender of its obligation to make a Loan hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder regardless of the failure of any other Lender to make a Loan hereunder.

(b) The Loan Commitment of each Lender shall be made available by such Lender during the Availability Period; provided, that in no event shall any Loans be available after the Final Availability Date.

2.4 Disbursement of Funds.

Subject to the terms and conditions hereof, no later than 5:00 p.m. (New York time) on the date specified in each Notice of Borrowing, each Lender will make available, through such Lender’s Applicable Lending Office, its pro rata portion of the aggregate amount of the Loans requested to be made on such date, in Dollars and in immediately available funds at the Payment Office of the Administrative Agent, and the Administrative Agent will pay the aggregate of the amounts so made available by the Lenders directly to the bank account of the Borrower as specified by the Borrower in the Notice of Borrowing. Unless the Administrative Agent shall have been notified by any Lender prior to the applicable date of the Borrowing that such Lender does not intend to make available to the Administrative Agent such Lender’s portion of the Borrowing on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date, and the Administrative Agent shall, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender on demand. The Administrative Agent shall also be entitled to recover on demand from such Lender interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower until the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to the cost to the Administrative Agent of acquiring overnight federal funds at the then applicable rate. Nothing in this Section 2.4 shall be deemed to relieve any Lender from its obligation to make a Loan hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any failure by such Lender to make Loans hereunder.

2.5 Evidence of Obligations.

(a) Each Lender will maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of the Borrower to such Lender as a result of the Loans of such Lender, including the amounts of principal, interest and other amounts payable and paid to such Lender from time to time under this Agreement. Absent manifest error, the entries made by each Lender pursuant to the foregoing sentence shall constitute prima facie evidence, of the existence and amounts of the Loans and other obligations therein recorded; provided, however, that the failure of any Lender to maintain such account or accounts shall not in any manner affect the obligations of the Borrower to repay or pay the Loan made by such Lender, accrued interest thereon and the other obligations of the Borrower to such Lender hereunder in accordance with the terms of this Agreement. Each Lender will advise the Borrower of the outstanding Indebtedness hereunder to such Lender upon written request therefor.

(b) If so requested after the Closing Date, by any Lender by written notice to the Borrower (with a copy to the Administrative Agent), the Borrower and the Guarantors (as guarantors under each Note (avalistas)) will, promptly following the end of the Availability Period, execute and deliver to such Lender, a non-negotiable Note in the form of Exhibit F attached hereto, evidencing the value of (i) the then outstanding aggregate principal amount or amounts of such Lender, together with (ii) the total interest payable by such Lender during the subsequent Interest Period to evidence the Loans of such Lender (each, an “Original Note” and, collectively, the “Original Notes”). With respect to any Lender that has received an Original Note, commencing at the end of the first Interest Period following the end of the Availability Period and at the end of each subsequent Interest Period, the Borrower shall promptly execute and deliver to the relevant Lender a Note evidencing the value of (i) the then outstanding aggregate principal amount or amounts of such Lender, together with (ii) the total interest payable by such Lender during the subsequent Interest Period to evidence the Loans of such Lender (each, a “Replacement Note” and, collectively, the “Replacement Notes”, and together with the Original Notes, the “Notes” and each, a “Note”). Following receipt of each Replacement Note, the applicable Lender shall promptly return the corresponding Original Note or previously issued Replacement Note such that at no point will any Lender be in the possession of more than one Note.

(c) Notwithstanding anything to the contrary contained above in this Section 2.5 or elsewhere in this Agreement, no failure of any Lender to request or obtain a Note evidencing its Loans to the Borrower shall affect or in any manner impair the obligations of the Borrower to pay the Loans (and all related Obligations) incurred by the Borrower which would otherwise be evidenced thereby in accordance with the requirements of this Agreement, and shall not in any way affect the security or guaranties therefor provided pursuant to the various Financing Documents.

2.6 Interest.

(a) The Borrower agrees to pay interest in respect of the unpaid and outstanding principal amount of each Loan from its Disbursement Date until the maturity of such Loan (whether by acceleration or otherwise), at a rate per annum which shall, during each Interest Period applicable thereto, be equal to the sum of (i) LIBOR in effect for such Interest Period and (ii) the applicable Margin.

(b) Overdue principal, interest and any other amount under or in connection with this Agreement shall bear interest (by way of liquidated damages and not as penalty) at a rate which is equal to the sum of (i) LIBOR in effect from time to time, (ii) the applicable Margin, and (iii) two per cent (2%) per annum, with such default interest (“Default Interest”) to be payable on demand.

(c) Accrued (and theretofore unpaid) interest shall be payable on each Interest Payment Date and, in respect of each Loan, on the date of any repayment or prepayment (on the amount repaid or prepaid), at maturity (whether by acceleration or otherwise) or, after such maturity, on demand. Notwithstanding the foregoing, Default Interest payable in accordance with Section 2.6(b) shall be payable as provided therein.

(d) On each Interest Determination Date, the Administrative Agent shall determine the LIBOR for

the applicable Interest Period to be applicable to the Loans or to any portion thereof and shall promptly notify the Borrower and the Lenders thereof. Each such determination shall, absent manifest error, be final and conclusive and binding on all parties hereto.

2.7 Interest Periods.

The interest period (an “Interest Period”) applicable to all Loans shall be a six (6) month period; provided, however, that:

(a) all Loans comprising the same Borrowing shall have the same Interest Periods;

(b) the initial Interest Period for any Loan shall commence on the Disbursement Date of such Loan and end on (but not include) the next succeeding Interest Payment Date, and each Interest Period occurring thereafter in respect of such Loan shall commence on (and include) an Interest Payment Date and end on (but not include) the next succeeding Interest Payment Date;

(c) if any Interest Period begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of such calendar month;

(d) if any Interest Period would otherwise end on a day that is not a Business Day, such Interest Period shall be extended to the next succeeding Business Day; and

(e) any Interest Period that would otherwise extend beyond the Loan Maturity Date shall instead end on the Loan Maturity Date.

2.8 Net Payments.

(a) All payments (including, without limitation, any fees, commissions or expenses paid by the Borrower to any Financing Parties) made by the Borrower hereunder or under any other Financing Document will be made without setoff, counterclaim or other similar defense. All such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, in the case of any Lender, any tax imposed on or measured by the net income, revenue, or gross receipts of such Lender pursuant to the laws of the jurisdiction in which it is organized or the jurisdiction in which the principal office or Applicable Lending Office of such Lender is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower agrees to pay such additional amounts as may be necessary so that the net amount received by the relevant Financing Party hereunder or under any other Financing Document, after withholding or deduction for or on account of any Taxes, will not be less than the amount provided for herein or in such Financing Document as if the corresponding deduction or withholding had not been made. The Borrower will furnish to the Administrative Agent within thirty (30) days after the date of the payment of any Taxes due pursuant to applicable law evidence of such payment in form and substance reasonably satisfactory to the Administrative Agent. The Borrower agrees to indemnify and hold harmless each Lender, and reimburse such Lender upon its written request, for the amount of any Taxes so levied or imposed and paid by such Lender.

(b) Each Lender and the Administrative Agent agree to complete in good faith and execute and deliver to the Borrower, in a timely manner, such form, certificates, information or documentation relating to such Lender or Administrative Agent to establish the extent to which any payments to such Lender or Administrative Agent are exempt from, or are entitled to a reduction of withholding or deduction of any Taxes (collectively, the “Forms”). Notwithstanding anything to the contrary herein, neither any Lender nor the Administrative Agent shall be required to provide any Forms pursuant to this Section 2.8(b) unless (i) such Forms are required by law as a condition to, or evidence of entitlement to, relief or exemption in whole or in part from any Taxes, (ii) such Lender

or the Administrative Agent is legally entitled to complete, execute and deliver such Forms and (iii) the Borrower shall have timely provided to such Lender or the Administrative Agent a written notice requesting that such Lender or the Administrative Agent execute and deliver such Forms together with the Forms and the official instructions thereto, if any.

(c) If the Borrower pays any additional amount under this Section 2.8 to a Lender and such Lender determines in its sole discretion that it has actually received or realized in connection therewith any refund or any reduction of, or credit against, its Tax liabilities in or with respect to the taxable year in which the additional amount is paid (a “Tax Benefit”), such Lender shall pay to the Borrower an amount that the Lender shall, in good faith, determine is equal to the net benefit, after tax, which was obtained by the Lender in such year as a consequence of such Tax Benefit; provided, however, that (i) any Lender may determine, in its sole discretion consistent with the policies of such Lender, whether to seek a Tax Benefit; (ii) nothing in this Section 2.8(c) shall require any Lender to disclose any confidential information to the Borrower (including, without limitation, its tax returns); and (iii) no Lender shall be required to pay any amounts pursuant to this Section 2.8(c) at any time when a Default or Event of Default exists.

(d) Notwithstanding anything to the contrary, the Borrower shall not be required pursuant to this Section 2.8 to pay any additional amount to, or to indemnify, any Lender or the Administrative Agent, as the case may be, to the extent that such Lender or the Administrative Agent becomes subject to Taxes subsequent to the Closing Date (or, if later, the date such Lender or Administrative Agent becomes a party to this Agreement) as a result of a change in the jurisdiction of organization of such Lender or Administrative Agent or a change in the location of the Applicable Lending Office of such Lender, except to the extent that any such change is requested or required in writing by the Borrower.

2.9 Illegality.

If, on or after the date hereof, the introduction of any Law, or any change in any Law, or in the official interpretation or administration of any Law, has made it unlawful, or that any central bank or other Governmental Authority has asserted that it is unlawful, for any Lender to make or to maintain its participation in a Loan, then:

(a) that Lender shall promptly provide written notice thereof to the Borrower through the Administrative Agent, setting out the relevant circumstances;

(b) on written notice thereof, any obligation of that Lender to make such Loan shall be suspended and the Loan Commitment of that Lender shall be immediately cancelled;

(c) the Borrower agrees to take all reasonable steps to obtain, as quickly as possible after receipt of such Lender’s request for prepayment pursuant to this Section 2.9, any Governmental Approvals then required in connection with such prepayment; and

(d) the Borrower shall repay that Lender’s participation in the Loans made to the Borrower on the Interest Payment Date immediately occurring after the Lender has notified the Borrower or, if earlier, the date specified by the Lender in the written notice delivered to the Borrower through the Administrative Agent (being no earlier than (i) the last day of any applicable grace period permitted by law, or (ii) twenty (20) Business Days after the delivery date of the written notice from the Lender, whichever occurs later) without any Break Cost, premium, penalty or fee of any nature.

2.10 Increased Costs and Reduction of Return.

(a) Subject to Section 10.13(f), if any Lender shall have determined, in good faith (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto), at any time that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to any Loan (other than any increased cost or reduction in the amount received or receivable resulting from

the imposition of or a change in any tax imposed on or measured by the net income, revenue, or gross receipts or similar charges or otherwise compensated for Taxes under Section 2.8) because of any change in any applicable law or governmental rule, regulation, order, guideline or request (whether or not having the force of law) or in the official interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, and including the introduction, after the Signing Date, of any new law or governmental rule, regulation, order, guideline or request, then, and in any such event, the Borrower shall pay to such Lender, within thirty (30) days of written demand therefor, such additional reasonable and duly documented amounts as shall be required to compensate such Lender for such increased costs or reductions in amounts received or receivable hereunder; provided, however, that before making any such demand each Lender agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender (a written notice by such Lender as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the Borrower by such Lender, shall, absent manifest error, be final and conclusive and binding on all parties hereto).

(b) If a Lender requests compensation under this Section 2.10 or if the Borrower is required to pay additional amounts to any Lender under Section 2.8 as a result of any internal reorganization of such Lender, then such Lender shall, in good faith consultation with the Borrower, take commercially reasonable steps to mitigate any circumstances giving arise to the gross-up under Section 2.8 or the indemnification under this Section 2.10, failing which, the Borrower shall be entitled to designate a Replacement Lender under Section 2.13. A Lender need not take any such steps if such Lender determines, in its reasonable opinion, that to do so would be materially prejudicial to it (it being understood that it is not prejudicial to the Lender to bear costs that the Borrower is willing to reimburse).

2.11 Inability to Determine Rates.

If, on or prior to the first day of any Interest Period (an “Affected Interest Period”): (a) the Administrative Agent determines that, by reason of circumstances affecting the London interbank market, LIBOR cannot be determined pursuant to the definition thereof; or (b) the Required Lenders determine and notify the Administrative Agent that the relevant rate of interest referred to in the definition of “LIBOR” upon the basis of which the rate of interest for Loans for such Affected Interest Period is to be determined will not be adequate to cover the cost to such Lenders of making or maintaining its Disbursements for such Affected Interest Period; or (c) the Screen Rate is not available or the Screen Rate is zero or negative and none or only one of the Reference Banks supplies a rate to the Administrative Agent to determine LIBOR for the relevant Interest Period, the Administrative Agent shall give notice thereof (a “Rate Determination Notice”) to the Borrower and the Lenders as soon as practicable thereafter. If such notice is given, during the thirty (30) day period following such Rate Determination Notice (the “Negotiation Period”) the Administrative Agent and the Borrower shall negotiate in good faith with a view to agreeing upon a substitute interest rate basis (having the written approval of all Lenders) for the Disbursements that shall reflect the cost to the Lenders of funding their Disbursements from alternative sources (a “Substitute Basis”), and if such Substitute Basis is so agreed upon during the Negotiation Period, such Substitute Basis shall apply in lieu of LIBOR to all Interest Periods commencing on or after the first day of the Affected Interest Period, until the circumstances giving rise to such notice have ceased to apply. During the Negotiation Period, the Lenders are not obliged to fund any Disbursement unless and until a Substitute Basis is agreed upon. If a Substitute Basis is not agreed upon during the Negotiation Period, each Lender shall, subject to compliance with applicable Brazilian laws and regulations, determine (and shall certify from time to time in a certificate delivered by such Lender to the Administrative Agent setting forth in reasonable detail the basis of the computation of such amount) the rate basis reflecting the cost to such Lender of funding its Loans for the Interest Period commencing on or after the first day of the Affected Interest Period, until the circumstances giving rise to such notice have ceased to apply, and such rate basis shall be binding upon the Borrower and such Lender and shall apply in lieu of LIBOR, as applicable, for the relevant Interest Period.

2.12 Survival.

(b) Each Lender authorizes the Administrative Agent to execute, deliver and perform each of the Financing Documents to which the Administrative Agent is or is intended to be a party and the Collateral Agency Agreement for the benefit of the Lenders and each Lender agrees to be bound by all of the agreements of the Administrative Agent contained in the Financing Documents and the Collateral Agency Agreement.

The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement, the Collateral Agency Agreement or any Financing Document (a) if such action would, in the opinion of the Administrative Agent (upon consultation with counsel), be contrary to applicable Law or the terms of any Financing Document or the Collateral Agency Agreement, (b) if such action is not specifically provided for in the Financing Documents to which the Administrative Agent is a party or the Collateral Agency Agreement, and it shall not have received such advice or concurrence of the Required Lenders as it deems appropriate, (c) if in connection with the taking of any such action that would constitute the making of a payment due under any Financing Document or the Collateral Agency Agreement, it shall not first have received from any or all of the other Financing Parties funds equal to the amount of such payment, or (d) unless, if it so requests, the Administrative Agent shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

8.5 Notice of Default.

The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except 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 Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “Notice of Default.” If the Administrative Agent receives any such notice of the occurrence of a Default or an Event of Default, it shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be requested by the Required Lenders in accordance with this Section 8; provided, however, that unless and until the Administrative Agent has received any such request, 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 Event of Default as it shall deem advisable or in the best interest of the Lenders.

Except for notices, reports and other documents expressly required pursuant to any Financing Document or the Collateral Agency Agreement to be furnished to the Lenders by the Administrative Agent, the Administrative Agent shall not 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 Project or of the Borrower which may come into the possession of the Administrative Agent or any of its Agent-Related Persons.

(a) Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand the Administrative Agent and its Agent-Related Persons (to the extent not reimbursed by or on behalf of the Borrower and without limiting the obligation of the Borrower to do so), pro rata in accordance with the aggregate principal amount of the Loans held by such Lender, from and against any and all Indemnified Liabilities; provided, however, that no Lender shall be liable for the payment to the Administrative Agent or its Agent-Related Persons of any portion of such Indemnified Liabilities resulting solely from such Person’s gross negligence or willful misconduct.

(b) Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share as provided above of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Administrative Agent 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, this Agreement, the Collateral Agency Agreement, any

Financing Document or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower.

The Lenders acknowledge that, pursuant to such activities, the Administrative Agent or its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrower or such Affiliates) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. The Administrative Agent which is also a Lender hereunder shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity.

Each Guarantor hereby acknowledges and agrees that no Financing Party nor any other Person shall be under any obligation to (i) marshal any assets in favor of such Guarantor or in payment of any or all of the liabilities of the Borrower or any other Guarantor under the Financing Documents or the obligation of such Guarantor hereunder or (ii) pursue any other remedy that such Guarantor may or may not be able to pursue itself, any right to which such Guarantor hereby waives.

9.9 Payments.

All payments made by each Guarantor pursuant to this Section 9 shall be made in Dollars and will be made without setoff, counterclaim or other defense (other than that the Guaranteed Obligations have been paid in full) that may at any time be available to or be asserted by the Borrower, such Guarantor or any Person against any Financing Party whether in connection with the Financing Documents or any unrelated transaction, and shall be subject to the provisions of Sections 2.8 and 6.4.

9.10 Continuing Guaranty.

This Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of any Financing Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein expressly specified are cumulative

and not exclusive of any rights or remedies which any Financing Party would otherwise have. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Financing Party to any other or further action in any circumstances without notice or demand. It is not necessary for any Financing Party to inquire into the capacity or powers of the Borrower or any Guarantor or the officers, directors, partners or agents acting or purporting to act on its or their behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

9.11 Limitation on Guaranteed Obligations.

Each Guarantor and each Financing Party (by its acceptance of the benefits of this Guaranty) hereby confirms that it is its intention that this Guaranty not constitute a fraudulent transfer or conveyance for purposes of any applicable Law. To effectuate the foregoing intention, each Guarantor and each Financing Party (by its acceptance of the benefits of this Guaranty) hereby irrevocably agrees that the Guaranteed Obligations guaranteed by such Guarantor shall be limited to such amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such laws and after giving effect to any rights to contribution pursuant to any agreement providing for an equitable contribution among such Guarantor and the other Guarantors, result in the Guaranteed Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance.

9.12 Maximum Liability.

It is the desire and intent of the Guarantors and the Financing Parties that this Guaranty shall be enforced against the Guarantors to the fullest extent permissible under the applicable Laws and public policies applied in each jurisdiction in which enforcement is sought. If, however, and to the extent that, the obligations of any of the Guarantors under this Guaranty shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers), then the amount of such Guarantor’s obligations under this Guaranty shall be deemed to be reduced and such Guarantor shall pay the maximum amount of the Guaranteed Obligations which would be permissible under applicable Law.

(e) Notwithstanding any other provision contained in this Agreement or any other Financing Document to the contrary, any Lender may pledge or assign as collateral security all or any portion of the Loans held by it; provided that (i) the pledge or assignment as collateral security, its enforcement and payment thereunder would not result in any increased costs or Taxes on the Borrower or the Guarantors, and (ii) any payment in respect of such assigned Loans made by the Borrower to or for the account of the assigning or pledging Lender in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in respect to such assigned Loan to the extent of such payment. No such assignment shall release the assigning Lender from its obligations hereunder.

(ii) as a result of circumstances existing at the date the assignment, transfer or change occurs, the Borrower would be obliged to make a payment to a permitted assignee or Lender acting through its new Applicable Lending Office under Sections 2.8 or 2.10, then the permitted assignee or Lender acting through its new Applicable Lending Office is only entitled to receive payment under those Sections to the same extent as the assigning Lender or Lender acting through its previous Applicable Lending Office would have been if the assignment, transfer or change had not occurred.

(g) Subject to actions permitted under clause 5.2(a) of the Fiduciary Assignment, the Borrower shall not assign or otherwise transfer any of its rights and obligations under this Agreement or any other Financing Document without the prior written consent of the Administrative Agent (acting on the instructions of all Lenders).

Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender; provided that any failure to give such notice shall invalidate such set-off and application.

10.17 Severability.

Any provision hereof 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, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Each party further agrees that that the United States District Court for the Southern District of New York and of the courts of the State of New York sitting in the County of New York, and any appellate court from any thereof, shall have exclusive jurisdiction with respect to any claim or counterclaim of any Obligor 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 agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party hereto hereby expressly and irrevocably waives, to the fullest extent permitted by applicable Law, the jurisdiction of any other courts to which it may be entitled to, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

(c) To the extent any Obligor may, in any action or proceeding arising out of or relating to any of the Financing Documents brought in Brazil or elsewhere, be entitled under any applicable Law to require or claim that any Financing Party post security for costs or take similar action, each Obligor hereby irrevocably waives and agrees, to the extent permitted by law, not to claim the benefit of such entitlement.

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. To the extent permitted by applicable Law, each Obligor further irrevocably agrees to the service of process of any of the aforementioned courts in any suit, action or proceeding by the mailing of copies thereof by certified mail, postage prepaid, return receipt requested, to the Borrower or the Guarantors, as the case may be, at the address referenced in Section 10.3, such service to be effective upon the date indicated on the postal receipt returned from the Borrower or the Guarantors, as the case may be.

(e) Each Obligor agrees that it will at all times continuously maintain an agent to receive service of process in the State of New York on behalf of itself and its Properties, and, in the event that for any reason the agent mentioned above shall not serve as agent for an Obligor to receive service of process in the State of New York on its behalf, the relevant Obligor shall promptly appoint a successor reasonably satisfactory to the Administrative Agent so to serve, advise the Administrative Agent thereof, and deliver to the Administrative Agent evidence in writing of the successor agent's acceptance of such appointment. 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.
