CLAUSE SEVEN - PAYMENT TERM - The Parties agree to amend Clause 9 of the CCB, as well as to include sub-clauses 9.1, 9.2, 9.2.1, 9.2.2 and 9.2.3, which shall read as follows:

"9. PAYMENT TERM - ISSUER undertakes to pay to CREDITOR the amounts related to this CCB, as follows:

a) Principal shall be paid in installments, with maturities and nominal values described in the payment schedule included in Annex I to this CCB, also observing the following: (i) the first Forty eight (48) months to count of January 31, 2018 shall be considered, for the purposes of this CCB, as the "Reduced Amortization Period"; (ii) the period of fifty (50) months subsequent to the Reduced 

Amortization Period shall be considered, for the purposes of this CCB, as the "Regular Amortization Period";

b) the Financial Charges, due on the Payment Dates of the Charges, in accordance with Clause 4 of this CCB, obliging us to settle together with the last installment of the Principal, according to the schedule set in Annex I, all the pecuniary obligations resulting from this CCB.

9.1. Notwithstanding the foregoing, to determine the payment terms, the following instruments shall also be considered:

		
	a)
	The Bank Credit Bill No. 21.3150.777.0000001-97, issued by ISSUER on December 08, 2011, in favor of CAIXA, in the original amount of six hundred and forty million Reais (BRL 640,000,000.00) (as amended, the “CAIXA CCB");

		
	b)
	Credit Agreement dated April 20, 2012, without the contracting of "Sinosure Insurance", entered into by ISSUER and China Development Bank ("CDB" and, together with CAIXA, “Financial Creditors"), in the original amount of two hundred and fifty million US dollars (USD 250,000,000.00) (as amended, "CDB non Sinosure Agreement"); and

		
	c)
	The Credit Agreement dated April 20, 2012, with the contracting of "Sinosure Insurance", entered into by ISSUER and CDB, in the original amount of two hundred and fifty million Dollars (USD 250,000,000) (as amended, "CDB Sinosure Agreement", together with CCB CAIXA, and CDB non-Sinosure Agreement, "Financial Agreements" and each individually, "Financial Agreement") (CDB non Sinosure Agreement and CDB Sinosure Agreement, hereinafter "CDB Agreements").

9.2. Except in relation to the payment by bank commission bond and costs and/or the rate relating to the renegotiation of the CDB Agreements to conform them to the CDB Terms and Conditions, any extraordinary payment under any Financial Agreement, for any reason whatsoever, including as a consequence of alteration of periodicity, due dates or amounts due according to time schedules provided ("Extraordinary Payments to Financial Creditors"), shall oblige ISSUER to make a proportional extraordinary payment to CREDITOR within a maximum period of ten (10) business days ("CCB Extraordinary Payment"), from the date of the event of the respective Extraordinary Payment to any of the Financial Creditors.

9.2.1. Except in the case described in Clause 9.2.2 below, the amount of the CCB Extraordinary Payment shall be calculated by applying the Extraordinary Payment Percentage, on the Outstanding Balance of the CCB at the time, being, for the purpose of this CCB, "Percentage of Extraordinary Payment" the percentage of amortization of principal, payments of interest, commissions and/or any other amount performed under the Extraordinary Payment to Financial Creditors, calculated based on the amount of the Extraordinary Payment to the Financial Creditors, divided by the balance due and not paid on the date immediately prior to the Extraordinary Payment to the Financial Creditors made, with respect to the respective Financial Agreement. For the purposes of clarification, in the case of Extraordinary Payment to Financial Creditor performed in favor of more than one Financial Creditor, for the purposes of this CCB, the highest value paid under any Financial Agreement, without duplication of calculation, shall be considered. 

9.2.2. In the event of any CCB Extraordinary Payment, all installments due to the Principal or Financial Charges, as the case may be, shall be automatically and proportionately reduced, with the remaining terms and conditions, including payments, established in the caput of this Clause 9, above. In the event that the CCB Extraordinary Payment occurs in relation to the Principal, the Parties shall amend the CCB in order to update the terms of Annex I, as the case may be, for legal purposes. If the CCB Extraordinary Payment refers to any additional remuneration to the Financial Creditors in comparison to the one provided for in the CDB Terms and Conditions, such Extraordinary Payment shall also be proportionally made to CREDITOR as an additional amount, without any change to the Outstanding Balance. 

9.2.3. Notwithstanding the provisions of this Clause 9, if at any time any Financial Agreement has provisions that, at CREDITOR's sole discretion, are more beneficial to the holders or creditors of said instruments in comparison to the terms of this CCB or the Guarantee Agreements, then CREDITOR shall have the right to require an amendment to this CCB or to the Guarantee Agreements, as applicable, so that such more favorable provisions may be extended, mutatis mutandis, to CREDITOR, except with respect to the provisions currently in force provided for in the CDB Agreements and/or to be provided in the instruments and amendments in compliance with the CDB Terms and Conditions, including the granting by NII Luxembourg of a corporate guarantee, in substitution of the parent guarantee originally granted by NII Holdings, Inc. in favor the CDB, under the terms of CDB Terms and Conditions."

ISSUER undertakes, irrevocably and irreversibly, (i) not to take measures to directly receive any amount related to BB Receivables; (ii) not materially change the procedures and forms of collection of BB Receivables currently in force, and not to take any action, or fail to take any measure, when applicable, that is aimed at or has the effect of reducing the collection of BB Receivables by CREDITOR, until the full satisfaction of the obligations of ISSUER provided in the CCB; (iii) during the validity of the CCB, to maintain in force the Collection Agreement; and (iv) not to assign, transfer, sell, encumber, pledge, engage or record or in any way negotiate the BB Assigned Rights, without the prior and express consent of CREDITOR.

12.5. It is agreed that the average monthly amount of the Collected Amounts that shall be transferred to the BB Blocked Account in the three months immediately prior to the calculation by CREDITOR in each quarter ("Period"), to be held on March 31, June 30, September 30 and December 31 of each year shall comprise - and ISSUER undertakes to adopt all necessary measures to ensure that it occurs - the minimum amount equivalent to thirty million Reais (BRL 30,000,000.00) ("Minimum Average Amount") , calculated by the total amount of resources that shall be deposited in the BB Blocked Account during each Period, divided by three (3). If, in a given Period, the Minimum Average Amount is not verified by CREDITOR, CREDITOR and/or Planner (as instructed 

by CREDITOR) must notify ISSUER, stating that the Minimum Average Amount has not been achieved in the Period, from which the ISSUER may use, at its sole discretion, up to the next Minimum Average Value Assessment, at least, cumulatively or alternatively, of the following cure mechanisms: (i) deposit the lacking amount in the BB Blocked Account; (ii) deliver a bank guarantee to CREDITOR, issued by a financial institution with a credit risk acceptable to CREDITOR, on terms and conditions satisfactory to it, valid for a period of at least one hundred and twenty (120) days, the principal amount of which shall be equivalent to the difference between the Minimum Average Amount and the amount actually calculated; (iii) deliver to CREDITOR a stand-by letter of credit issued by an institution with a credit risk acceptable to CREDITOR, in terms and conditions satisfactory to it, valid for a period of at least one hundred and twenty (120) days, the principal amount of which shall be equivalent to the difference between the Minimum Average Amount and the amount actually calculated; and/or (iv) provide other guarantees acceptable to CREDITOR, in the amount equivalent to the difference between the Minimum Average Amount and the amount actually calculated. ISSUER may cure the Minimum Average Amount as many times as necessary. Solely in the event that ISSUER does not cure the Minimum Average Value, such event shall be characterized as an Event of Default, enabling the occurrence of an Event of Acceleration without any form or period of additional cure. Bank guarantee and/or standby letters of credit issued under the terms of this Clause shall have the power to cure only the default of the Minimum Average Amount referring to a single Period and it is not possible to use the same bank guarantee and/or letter of standby credit for remedy of default of more than one Period. In the event of a remedy in two subsequent periods and if the bank guarantee and/or standby credit letters for remedy of the second period are already in force, ISSUER is authorized to request CREDITOR to return to the financial institution issuing the original bank guarantee and/or standby credit letters issued for the cure of the first Verification Period. Notwithstanding the provisions of this Clause, CREDITOR is hereby authorized to withdraw, at the occurrence of Event of Aceleration or in case of a mandatory prepayment event, the available amount of the bank guarantee and/or standby credit letters that are issued to remedy the Minimum Average Amount in the most recent Period.

12.6. Without prejudice to the provisions of the Clause below, CREDITOR, from this act, legally identified as the legitimate owner, in a fiduciary character, of the BB Assigned Rights, whose condition shall last until the full compliance of all obligations assumed by ISSUER in the CCB, so that, in the event of its compliance by ISSUER, as certified by CREDITOR, the fiduciary property of CREDITOR shall be resolved, returning the BB Assigned Rights to the full ownership of ISSUER, except, however, that such BB Assigned Rights that remain, after full payment of this CCB, shall 

remain subject to the liens provided for in the Deed of Assignment of Receivables, in accordance with its terms, in favor of the Financial Creditors.

12.7. ISSUER hereby states that:

(i) it is authorized, pursuant to the law, to its articles of association and other corporate approvals obtained, to execute and comply with the provisions of this CCB;

(ii) the execution and fulfillment of the obligations of this CCB do not violate any provision of its articles of association, nor do they infringe or violate any legal provision and regulations to which they are subject;

(iii) BB Assigned Rights are free and clear of any liens, charges, judicial or extrajudicial cases of any nature, including fiscal, doubts, debts and/or liens of any nature, except for the fiduciary assignment established hereunder;

(iv) there is no impediment contained in covenants of which ISSUER is a party, which prevents the fiduciary assignment of the BB Assigned Rights; the execution of this CCB does not matter the noncompliance or early maturity of any other covenants of which ISSUER is a party; and

(v) it had prior, clearly and sufficiently knowledge of the attributions imposed on it, and which abrogates all terms of the CCB.

12.8. ISSUER shall be liable for any and all damages caused to CREDITOR arising from the falsehood or inaccuracy of the statements and warranties provided herein.

12.9. Upon the occurrence of an Event of Default in relation to the obligations assumed by ISSUER in the CCB, observing the respective cure periods, as applicable, all amounts related to the BB Assigned Rights shall be retained by CREDITOR in the BB Blocked Account and, in case of an Event of Declaration of Early Maturity of the debt or hypothesis of obligatory prepayment under the terms hereof, they may be used in the amortization of said obligations of ISSUER, until the full settlement of the Secured Obligations, under the terms hereof. 

12.10. In case of the Event of Declaration of Early Maturity of the debt hereunder, CREDITOR may, regardless of any notification, promote the immediate use of the BB Assigned Rights to satisfy the Secured Bonds then expired and not settled, by judicial excuse or friendly sale of the BB Assigned Rights, as applicable, or, in the case of the Transferred Securities, simply apply them in the payment of the Secured Obligations, pursuant to the law and in accordance with the terms hereof, until the total performance of the Secured Obligations. In this sense, CREDITOR shall have the right to immediately exercise on the BB Assigned Rights all the powers granted to it by the legislation in force, under the terms of the CCB, and may dispose of, collect, receive, perform, sell, or grant, including in whole or in part, the BB Assigned Rights, under such terms and conditions, as CREDITOR deems appropriate, to grant discharge and sign any documents or terms, however special, necessary for the performance of the acts herein, irrespective of any communication and/or additional authorization from ISSUER. Any remaining value of the Secured Obligations shall be returned to ISSUER.

12.11. ISSUER hereby waives any legal or contractual right or privilege that may affect the free and integral feasibility and transfer of the BB Assigned Rights in the event of its termination, subject to the terms and conditions set forth herein.

12.12. Without prejudice to the provided herein, and for the purposes of article 1,362 of the Brazilian Civil Code, Law 9,514/97, as amended, and Law 4,728/65, as amended, the Guaranteed Obligations can be briefly described as follows:

The referred Financial Charges, calculated by business days, shall be charged on a monthly basis to the Current Account and shall be fully paid on a monthly basis, on the corresponding Payment Date of the Charges, as defined in item 1.2 of the Preamble and Clause 9, below, in the monthly installments. For purposes of this CCB, the Parties agree to delete all references to "Loan Account". For the purposes of demonstrating the amounts owed by ISSUER, the debits and credits corresponding to the accounting entries related to the transactions carried out in the Current Account, under the terms of this CCB, will be observed.

7.1. In the hypothesis of Caput, we shall pay to CREDITOR a rate equivalent (i) to zero point fifty percent (0.50%) on the amount settled/amortized in advance, due on the amortization/settlement date, if such amortization/settlement occurs during the course of the first (1st) year of term of this CCB; (ii) zero point thirty percent (0.30%) if it occurs during the second (2nd) year of its term and

FLAT COMMISSION - In addition to the financial charges agreed upon, we shall pay to CREDITOR, on account of the advice on structuring and raising funds, a structuring fee of zero point ten percent (0.10%), calculated on the principal and required value on the date of its full release and whose incident retained taxes shall be the responsibility of this ISSUER. We authorize CREDITOR to debit in our Current Account, upon notice, the amount due for such title.

9. PAYMENT TERM - ISSUER undertakes to pay to CREDITOR the amounts related to this CCB, as follows:

b) the Financial Charges, due on the Payment Dates of the Charges, in accordance with Clause 4 of this CCB, obliging us to settle together with the last installment of the Principal, according to the schedule set in Annex I, all the pecuniary obligations resulting from this CCB.

9.1. Notwithstanding the foregoing, to determine the payment terms, the following instruments shall also be considered:

		
	(a)
	The Bank Credit Bill No. 21.3150.777.0000001-97, issued by ISSUER on December 08, 2011, in favor of CAIXA, in the original amount of six hundred and forty million Reais (BRL 640,000,000.00) (as amended, the “CAIXA CCB");

		
	(b)
	Credit Agreement dated April 20, 2012, without the contracting of "Sinosure Insurance", entered into by ISSUER and China Development Bank ("CDB" and, together with CAIXA, “Financial Creditors"), in the original amount of two hundred and fifty million US dollars (USD 250,000,000.00) (as amended, "CDB non Sinosure Agreement"); and

		
	(c)
	The Credit Agreement dated April 20, 2012, with the contracting of "Sinosure Insurance", entered into by ISSUER and CDB, in the original amount of two hundred and fifty million Dollars (USD 250,000,000) (as amended, "CDB Sinosure Agreement", together with CCB CAIXA, and CDB non-Sinosure Agreement, "Financial Agreements" and each individually, "Financial Agreement") (CDB non Sinosure Agreement and CDB Sinosure Agreement, hereinafter "CDB Agreements").

9.2. Except in relation to the payment by bank commission bond and costs and/or the rate relating to the renegotiation of the CDB Agreements to conform them to the CDB Terms and Conditions, any extraordinary payment under any Financial Agreement, for any reason whatsoever, including as a consequence of alteration of periodicity, due dates or amounts due according to time schedules provided ("Extraordinary Payments to Financial Creditors"), shall oblige ISSUER to make a proportional extraordinary payment to CREDITOR within a maximum period of ten (10) business days ("CCB Extraordinary Payment"), from the date of the event of the respective Extraordinary Payment to any of the Financial Creditors.

9.2.1. Except in the case described in Clause 9.2.2 below, the amount of the CCB Extraordinary Payment shall be calculated by applying the Extraordinary Payment Percentage, on the Outstanding Balance of the CCB at the time, being, for the purpose of this CCB, "Percentage of Extraordinary Payment" the percentage of amortization of principal, payments of interest, commissions and/or any other amount performed under the Extraordinary Payment to Financial Creditors, calculated based on the amount of the Extraordinary Payment to the Financial Creditors, divided by the balance due and not paid on the date immediately prior to the Extraordinary Payment to the Financial Creditors made, with respect to the respective Financial Agreement. For the purposes of clarification, in the case of Extraordinary Payment to Financial Creditor performed in favor of more 

than one Financial Creditor, for the purposes of this CCB, the highest value paid under any Financial Agreement, without duplication of calculation, shall be considered. 

9.2.2. In the event of any CCB Extraordinary Payment, all installments due to the Principal or Financial Charges, as the case may be, shall be automatically and proportionately reduced, with the remaining terms and conditions, including payments, established in the caput of this Clause 9, above. In the event that the CCB Extraordinary Payment occurs in relation to the Principal, the Parties shall amend the CCB in order to update the terms of Annex I, as the case may be, for legal purposes. If the CCB Extraordinary Payment refers to any additional remuneration to the Financial Creditors in comparison to the one provided for in the CDB Terms and Conditions, such Extraordinary Payment shall also be proportionally made to CREDITOR as an additional amount, without any change to the Outstanding Balance. 

9.2.3. Notwithstanding the provisions of this Clause 9, if at any time any Financial Agreement has provisions that, at CREDITOR's sole discretion, are more beneficial to the holders or creditors of said instruments in comparison to the terms of this CCB or the Guarantee Agreements, then CREDITOR shall have the right to require an amendment to this CCB or to the Guarantee Agreements, as applicable, so that such more favorable provisions may be extended, mutatis mutandis, to CREDITOR, except with respect to the provisions currently in force provided for in the CDB Agreements and/or to be provided in the instruments and amendments in compliance with the CDB Terms and Conditions, including the granting by NII Luxembourg of a corporate guarantee, in substitution of the parent guarantee originally granted by NII Holdings, Inc. in favor the CDB, under the terms of CDB Terms and Conditions.

12. CONSTITUTION OF REAL GUARANTEE - In order to ensure compliance with the obligations assumed in the CCB ("Guaranteed Obligations"), and in addition to the fiduciary assignment hereby constituted, pursuant to Clause 12.1 below, ISSUER has cumulatively provided the following guarantees: (i) Fiduciary Assignment of Receivables, Rights and Bank Accounts, pursuant to the Deed of Assignment of Receivables, Rights, and Bank Accounts, entered into between ISSUER, CREDITOR, CAIXA ECONOMICA FEDERAL ("CAIXA"), CHINA DEVELOPMENT BANK ("CDB") and Planner Trustee Distribuidora de Títulos e Valores Mobiliários Ltda.

12.1. For the purposes of the fiduciary assignment already established, ISSUER fiduciary assigns and transfers to CREDITOR, irrevocably and irreversibly, by this act and in the best form of law, pursuant to paragraph 3 of article 66-B of Law No. 4,728/65, as amended by Law No. 10,931/04, articles 18 to 20 of Law No. 9,514/97, and Decree Law No. 911/69 and subsequent amendments, and as applicable of articles 1,361 an onwards of the Brazilian Civil Code (jointly, the “BB Granted Rights”), (a) the ownership, resolvable domain and direct and indirect ownership of all receivables, present and future, arising from the provision of telecommunications services performed by ISSUER to its customers, covering all revenue from amounts received in this respect, which are collected by CREDITOR ("BB Receivables"), under the terms of the Collection Agreement (as defined below), as well as (b) the resources deposited or held in the BB Blocked Account, and (c) the BB Blocked Account.

12.2. The amounts related to the part of the BB Receivables referred to in the caput are received by CREDITOR through the collection of non-compensable guides and automatic debit, in accordance with the Term of Adhesion to the General Clauses of the Single Service Agreement entered into between CREDITOR and ISSUER on 12/11/2014 ("Collection Agreement").

12.3. The amounts received daily under the Collection Agreement ("Collected Amounts"), representing a portion of the BB Receivables and any other credits, shall be credited to the BB Blocked Account, whose balance and amounts credited thereon daily are also hereby assigned by ISSUER to CREDITOR, integrating, for all purposes, the BB Assigned Rights, pursuant to the caput of this Clause. Likewise, under the terms of the Deed of Assignment of Receivables, the amounts from the Receivables Account (as defined in the Deed of Assignment of Receivables), corresponding to the percentage attributable to CREDITOR of the Receivables (as such term is defined in the Deed of Assignment of Receivables), which shall be deposited in the BB Blocked Account, shall integrate the definition of Collected Amounts and shall be computed for purposes of calculating the Minimum Average Value, as defined in Clause 12.5 below.

12.4. ISSUER undertakes, irrevocably and irreversibly, (i) not to take measures to directly receive any amount related to BB Receivables; (ii) not materially change the procedures and forms of collection of BB Receivables currently in force, and not to take any action, or fail to take any measure, when applicable, that is aimed at or has the effect of reducing the collection of BB Receivables by CREDITOR, until the full satisfaction of the obligations of ISSUER provided in the CCB; (iii) during the validity of the CCB, to maintain in force the Collection Agreement; and (iv) not to assign, transfer, sell, encumber, pledge, engage or record or in any way negotiate the BB Assigned Rights, without the prior and express consent of CREDITOR.

If, in a given Period, the Minimum Average Amount is not verified by CREDITOR, CREDITOR and/or Planner (as instructed by CREDITOR) must notify ISSUER, stating that the Minimum Average Amount has not been 

achieved in the Period, from which the ISSUER may use, at its sole discretion, up to the next Minimum Average Value Assessment, at least, cumulatively or alternatively, of the following cure mechanisms: (i) deposit the lacking amount in the BB Blocked Account; (ii) deliver a bank guarantee to CREDITOR, issued by a financial institution with a credit risk acceptable to CREDITOR, on terms and conditions satisfactory to it, valid for a period of at least one hundred and twenty (120) days, the principal amount of which shall be equivalent to the difference between the Minimum Average Amount and the amount actually calculated; (iii) deliver to CREDITOR a stand-by letter of credit issued by an institution with a credit risk acceptable to CREDITOR, in terms and conditions satisfactory to it, valid for a period of at least one hundred and twenty (120) days, the principal amount of which shall be equivalent to the difference between the Minimum Average Amount and the amount actually calculated; and/or (iv) provide other guarantees acceptable to CREDITOR, in the amount equivalent to the difference between the Minimum Average Amount and the amount actually calculated. ISSUER may cure the Minimum Average Amount as many times as necessary. Solely in the event that ISSUER does not cure the Minimum Average Value, such event shall be characterized as an Event of Default, enabling the occurrence of an Event of Acceleration without any form or period of additional cure. Bank guarantee and/or standby letters of credit issued under the terms of this Clause shall have the power to cure only the default of the Minimum Average Amount referring to a single Period and it is not possible to use the same bank guarantee and/or letter of standby credit for remedy of default of more than one Period. In the event of a remedy in two subsequent periods and if the bank guarantee and/or standby credit letters for remedy of the second period are already in force, ISSUER is authorized to request CREDITOR to return to the financial institution issuing the original bank guarantee and/or standby credit letters issued for the cure of the first Verification Period. Notwithstanding the provisions of this Clause, CREDITOR is hereby authorized to withdraw, at the occurrence of Event of Aceleration or in case of a mandatory prepayment event, the available amount of the bank guarantee and/or standby credit letters that are issued to remedy the Minimum Average Amount in the most recent Period.

Without prejudice to the provisions of the Clause below, CREDITOR, from this act, legally identified as the legitimate owner, in a fiduciary character, of the BB Assigned Rights, whose condition shall last until the full compliance of all obligations assumed by ISSUER in the CCB, so that, in the event of its compliance by ISSUER, as certified by CREDITOR, the fiduciary property of CREDITOR shall be resolved, returning the BB Assigned Rights to the full ownership of ISSUER, except, however, that such BB Assigned Rights that remain, after full payment of this CCB, shall 

remain subject to the liens provided for in the Deed of Assignment of Receivables, in accordance with its terms, in favor of the Financial Creditors.

12.7. ISSUER hereby states that:

(iv) there is no impediment contained in covenants of which ISSUER is a party, which prevents the fiduciary assignment of the BB Assigned Rights; the execution of this CCB does not matter the noncompliance or early maturity of any other covenants of which ISSUER is a party; and

(v) it had prior, clearly and sufficiently knowledge of the attributions imposed on it, and which abrogates all terms of the CCB.

12.8. ISSUER shall be liable for any and all damages caused to CREDITOR arising from the falsehood or inaccuracy of the statements and warranties provided herein.

12.9. Upon the occurrence of an Event of Default in relation to the obligations assumed by ISSUER in the CCB, observing the respective cure periods, as applicable, all amounts related to the BB Assigned Rights shall be retained by CREDITOR in the BB Blocked Account and, in case of an Event of Declaration of Early Maturity of the debt or hypothesis of obligatory prepayment under the terms hereof, they may be used in the amortization of said obligations of ISSUER, until the full settlement of the Secured Obligations, under the terms hereof. 

12.10. In case of the Event of Declaration of Early Maturity of the debt hereunder, CREDITOR may, regardless of any notification, promote the immediate use of the BB Assigned Rights to satisfy the Secured Bonds then expired and not settled, by judicial excuse or friendly sale of the BB Assigned Rights, as applicable, or, in the case of the Transferred Securities, simply apply them in the payment of the Secured Obligations, pursuant to the law and in accordance with the terms hereof, until the total performance of the Secured Obligations. In this sense, CREDITOR shall have the right to immediately exercise on the BB Assigned Rights all the powers granted to it by the legislation in force, under the terms of the CCB, and may dispose of, collect, receive, perform, sell, or grant, including in whole or in part, the BB Assigned Rights, under such terms and conditions, as CREDITOR deems appropriate, to grant discharge and sign any documents or terms, however special, necessary for the performance of the acts herein, irrespective of any communication and/or additional authorization from ISSUER. Any remaining value of the Secured Obligations shall be returned to ISSUER.

12.11. ISSUER hereby waives any legal or contractual right or privilege that may affect the free and integral feasibility and transfer of the BB Assigned Rights in the event of its termination, subject to the terms and conditions set forth herein.

12.12. Without prejudice to the provided herein, and for the purposes of article 1,362 of the Brazilian Civil Code, Law 9,514/97, as amended, and Law 4,728/65, as amended, the Guaranteed Obligations can be briefly described as follows:

CREDIT COMPENSATION - We authorize CREDITOR, irrevocably and irreversibly, regardless of previous notice, to proceed with the compensation provided for in article 368 of the Brazilian Civil Code, between CREDITOR's credit, corresponding to the outstanding balance presented in the Current Account, and the credits of any nature that we have or may have with CREDITOR.

17. SPECIAL OBLIGATIONS - ISSUER represents and warrants for all effects that any and all obligations assumed by ISSUER to any of its Related Parties are subordinated to the obligations set forth in this CCB. Likewise, ISSUER agrees that no amount shall be paid to its Related Parties prior to the full settlement of the obligations set forth in this CCB, including in the event of bankruptcy, settlement or dissolution of ISSUER, except for any payments made between ISSUER and GUARANTOR.

17.1. In order to prove compliance with the obligations under the Support Agreement by the Parent Company, ISSUER undertakes to submit to CREDITOR, within fifteen (15) business days of the respective event, documents evidencing increases in capital or advances for a future capital 

increase, irrevocably and irreversibly, as the case may be, for ISSUER's "Shareholders' Equity" account, and at the end of the Reduced Amortization Period, ISSUER shall have proved to CREDITOR the performance of the contributions of which this Clause and the Support Agreement deal of amounts in a minimum amount, in Reais, equivalent to two hundred and seventy million dollars (USD 270,000,000.00), including contributions already made between August 2017 and January 31, 2018, of which two hundred and seventy million Dollars (USD 270,000,000.00) shall include the taxes applicable to the internalization of such resources in Brazil, but shall be settled of any fees or commissions paid for such internalization.

18. MINIMUM BALANCE - ISSUER shall keep cash on the last business day of each month, immediately available resources or financial investments with daily liquidity in the minimum value, in Reais, equivalent to twenty million dollars (USD 20,000,000.00), observing the conversion rate of the Dollar by PTAX 800, Option 5, as disclosed by SISBACEN of the Central Bank of Brazil ("Minimum Balance"), and shall prove to CREDITOR, through bank statements of the current accounts of ISSUER. In order to comply with this obligation, ISSUER shall deliver to Planner and CREDITOR, within five (5) business days after the closing of each month, the bank statements necessary to prove the Minimum Balance ("Verification Date").

18.1. If the Minimum Balance is not observed, ISSUER shall have a cure period of three (3) business days counted from the end of each Verification Date. ISSUER may cure the default by demonstrating the deposit of the outstanding amount in an account held with any financial institution other than CREDITOR or CAIXA and provided that it is not an account fiduciary assigned to CDB, equivalent to the difference between the Minimum Balance required for said month and the amount actually calculated. ISSUER may not use the Minimum Balance remedy mechanism for more than two (2) times during the term hereof.
 
19. ASSIGNMENT - This CCB may be subject to assignment and endorsement by CREDITOR, upon prior notice of ten (10) business days prior to ISSUER, under the terms of civil and commercial legislation, and there is no need for the assignee/endorser to be a financial institution or entity treated as such. While a Default Event does not occur, the assignment referred to in this Clause shall not apply to ISSUER's competitor and/or entity belonging to a group that directly or indirectly operates the telecommunication tower rental activity.

20. ATORNEYS FEES - In the event that CREDITOR has to use means of collection to receive its credit, we are obliged to pay legal fees on the amount of the debit found in the extrajudicial charges, according to what has been agreed previously and in writing between ISSUER and CREDITOR, and in judicial collections according to what is decided by the Judicial power.

21. COLLECTION CALCULATION SPREADSHEETS - The Outstanding Balance shall be shown by CREDITOR in the strict terms of this CCB, by means of spreadsheets elaborated for the purpose of judicial or extrajudicial collection, which shall integrate this CCB for all legal purposes, the amounts used, any debt repayments, financial charges and default charges on the credit used.
