Estimated Accrued Tax Contingencies Adjustment resulting therefrom; and (ii) a schedule (the “Payout Schedule”) showing the AI Brazil Percentage, the Company Percentage, the Closing AI Brazil Payment and Closing NIIH Payment
resulting therefrom. For the avoidance of doubt, each of Seller and AI Brazil acknowledges and agrees that, unless the Payout Schedule is accompanied by a written notice executed by each of NIIH and AI Brazil specifying different percentages (which
percentages shall aggregate to 100%), the AI Brazil Percentage shall be deemed to be 29.9999997% and the Company Percentage shall be deemed to be 70.0000003% for all purposes under this Agreement. The Estimated Closing Statement and the Payout
Schedule shall be prepared in good faith and the Estimated Closing Statement shall be prepared in accordance with the Accounting Principles. Parent shall consider in good faith any objections of Purchaser to the Estimated Closing Statement and, if
Parent has determined in good faith that any revisions are required in order to cause the Estimated Closing Statement to comply with the terms of this Agreement, Parent will reissue an Estimated Closing Statement no later than 5:00 p.m., New
York City time, on the last Business Day immediately prior to the Closing Date, reflecting such revisions. Each of Parent, Seller and AI Brazil acknowledges and agrees that, in making the payments required to be made by

  
 30 

 
Purchaser pursuant to this ARTICLE 2, Purchaser shall be entitled to rely on the accuracy of the AI Brazil Percentage, the Company Percentage, the Closing AI Brazil Payment and Closing
NIIH Payment set forth in the Payout Schedule, and neither Purchaser nor, following the Closing, the Company shall have any liability to Seller or AI Brazil with respect to any claim that the amounts payable to Seller or AI Brazil, as the case may
be, as set forth on the Payout Schedule are incomplete or inaccurate or that Seller or AI Brazil, as the case may be, was entitled to receive payment of any different amount, in each case with respect to the Acquired Equity Interests or AI Brazil
Shares transferred by Seller or AI Brazil, as the case may be, subject to any adjustment thereto in accordance with Section 2.4(g) and to the actual payment of the amounts set forth in the Payout Schedule to Seller or AI
Brazil, as the case may be. For the avoidance of doubt, none of the Estimated Closing Statement, the Payout Schedule or any constituent part thereof shall include and in no event shall the Closing AI Brazil Payment be reduced as a result of, any
reserve, set aside, deduction or similar amount in respect of any potential claim by Purchaser of any breach or purported breach by Parent, Seller or the Entities of any of their respective representations and warranties or obligations under this
Agreement, in the understanding that any reduction in the Final Purchase Price made pursuant to the third sentence of Section 2.4(a) shall be entirely allocated to, and borne by, Seller. 

2.3. Payment of Purchase Price. On the Closing Date, Purchaser will: 

(a) pay the Closing NIIH Payment to NIIH, by wire transfer of immediately available funds to the account designated by NIIH in writing no later
than two Business Days prior to the Closing Date; 
 (b) on behalf of the Company, pay the Closing AI Brazil Payment to AI Brazil by wire
transfer of immediately available funds to an account designated in writing by AI Brazil no later than two Business Days prior to the Closing Date; 

(c) deposit the Escrow Amount with the Escrow Agent, by wire transfer of immediately available funds, to be held in the Escrow Account in
accordance with the Escrow Agreement; 
 (d) deposit the Convertible Notes Escrow Amount with the escrow agent for the Parent Convertible
Notes, by wire transfer of immediately available funds, in the event that the Indenture has not been amended in accordance with Section 8.20(a) or Parent has not made the escrow deposit contemplated by
Section 8.20(b); and 
 (e) on behalf of Nextel Brazil, pay the Pay-Off
Amount to each of the recipients specified in each of the Pay-Off Letters by wire transfer of immediately available funds to the accounts specified in such Pay-Off
Letters. 

  
 31 

 2.4. Purchase Price Adjustment. 

(a) As promptly as practicable following the Closing Date (but in any event within 45 days thereafter), Purchaser will prepare, or cause to be
prepared, and deliver to Parent and AI Brazil a certificate executed by a duly authorized representative of Purchaser (the “Closing Statement”) consisting of Purchaser’s calculation of Closing Net Working Capital, Net Working
Capital Adjustment, Capex Spend, the Selling and Marketing Cost Adjustment Amount, Closing USD Indebtedness, Closing BRL Indebtedness, Closing Indebtedness Adjustment, Closing USD Cash, Closing BRL Cash and Closing Cash Adjustment, together with the
calculation of the Final Purchase Price and Final AI Brazil Payment resulting therefrom, and Purchaser’s calculation of Unpaid Transaction Expenses, Closing Accrued Tax Contingencies and the Accrued Tax Contingencies Adjustment resulting
therefrom. The Closing Statement will be prepared in good faith and in accordance with the Accounting Principles. For the avoidance of doubt, if the Final Purchase Price would be lower but for the breach by Seller of any of its obligations
hereunder, Purchaser may present such lower Final Purchase Price in the Closing Statement, in the understanding that any resulting reduction in the Final Purchase Price shall be entirely allocated to, and borne by, Seller. Parent and NIIH represent
and warrant that Parent or its applicable Subsidiary has classified contingent Tax liabilities of the Entities as “probable”, “possible” or “remote” in accordance with the Accounting Principles for purposes of
determining Target Accrued Tax Contingencies, and each of Parent and Purchaser agrees that it shall not change such classifications for purposes of determining Estimated Closing Accrued Tax Contingencies or Closing Accrued Tax Contingencies,
respectively, except as expressly set forth in the Accounting Principles. 
 (b) The Closing Statement will become final, binding and
conclusive upon Parent, Seller, AI Brazil and Purchaser on the 45th day following Purchaser’s delivery of the Closing Statement unless, prior to such 45th day, Parent (on behalf of Seller and AI Brazil) delivers to Purchaser a written notice (a
“Closing Statement Dispute Notice”) stating that Parent disputes one or more items contained in the Closing Statement (a “Disputed Item”) and describing in reasonable detail each Disputed Item based on information
then available to Parent. 
 (c) If Parent delivers a Closing Statement Dispute Notice, then Purchaser and Parent, on behalf of Seller and AI
Brazil, will seek in good faith to resolve the Disputed Items during the 30-day period beginning on the date Purchaser receives the Closing Statement Dispute Notice (the “Resolution Period”).
If Purchaser and Parent reach agreement with respect to any Disputed Items, Purchaser will revise the Closing Statement to reflect such agreement. 

(d) If Purchaser and Parent are unable to resolve all Disputed Items during the Resolution Period, then Purchaser and Parent will jointly
engage and submit the unresolved Disputed Items (the “Unresolved Items”) to PricewaterhouseCoopers or, if such firm is unwilling or unable to serve, to Deloitte & Touche LLP (any such Person, the “Independent
Accountant”). Purchaser and Parent will use their respective reasonable best efforts to cause the Independent Accountant to issue its written determination regarding the Unresolved Items within 30 days after such items are submitted for
review. The scope of the disputes to be resolved by the Independent Accountant will be to make a determination with respect to the Unresolved Items in accordance with the Accounting Principles and this Section 2.4(d), and
the Independent 

  
 32 

 
Accountant is not to make any other determination. The Independent Accountant’s decision will be based solely on written submissions by Purchaser and Parent. Each of Purchaser’s and
Parent’s written submission to the Independent Accountant will also be provided to the other Party. For each Unresolved Item, the Independent Accountant shall assign a value equal to either the value for such item claimed by Purchaser or the
value claimed by Parent, and no other value, as the resolution of such item. Purchaser and Parent each will be afforded the opportunity to present to the Independent Accountant any material such Party deems relevant to the Independent
Accountant’s determination. Each of Purchaser and Parent will use its commercially reasonable efforts to furnish to the Independent Accountant such work papers and other documents and information pertaining to the Unresolved Items as the
Independent Accountant may request. The determination of the Independent Accountant will be final, binding and conclusive on the Parties absent manifest error. The “Final Purchase Price” means the Purchase Price as calculated based
upon the Closing Net Working Capital, Net Working Capital Adjustment, Capex Spend, the Selling and Marketing Cost Adjustment Amount, Closing USD Indebtedness, Closing BRL Indebtedness, Closing USD Cash, Closing BRL Cash, in each case, as and when
finally determined in accordance with Section 2.4(b), Section 2.4(c) or this Section 2.4(d), as the case may be; the “Final Unpaid Transaction
Expenses” means Unpaid Transaction Expenses as and when finally determined in accordance with Section 2.4(b), Section 2.4(c) or this Section 2.4(d); and
the “Final Accrued Tax Contingencies Adjustment” means the Accrued Tax Contingencies Adjustment as calculated based upon the Closing Accrued Tax Contingencies as and when finally determined in accordance with
Section 2.4(b), Section 2.4(c) or this Section 2.4(d); provided that, if Target Accrued Tax Contingencies exceed the Closing Accrued Tax Contingencies (as and when
finally determined in accordance with Section 2.4(b), Section 2.4(c) or this Section 2.4(d)), then (A) if the Net Working Capital Adjustment Cap exceeds Net Working
Capital Adjustment (as and when finally determined in accordance with Section 2.4(b), Section 2.4(c) or this Section 2.4(d)), the Final Accrued Tax Contingencies
Adjustment shall not exceed an amount equal to the lesser of (1) the difference between the Net Working Capital Adjustment Cap and the Net Working Capital Adjustment (as and when finally determined in accordance with
Section 2.4(b), Section 2.4(c) or this Section 2.4(d)) and (2) the Accrued Tax Contingencies Adjustment Cap or (B) if the Net Working Capital Adjustment (as and
when finally determined in accordance with Section 2.4(b), Section 2.4(c) or this Section 2.4(d)) exceeds the Net Working Capital Adjustment Cap, then the Final Accrued
Tax Contingencies Adjustment shall be $0. 
 (e) The fees, expenses and costs of the Independent Accountant will be borne by Purchaser, on
the one hand, and Parent, on the other hand, in the same proportion as the aggregate amount of the Unresolved Items that is unsuccessfully disputed by each of Purchaser and Parent (as finally determined by the Independent Accountant) bears to the
total amount of the Unresolved Items submitted to the Independent Accountant. 

  
 33 

 (f) Seller will provide Purchaser and its Representatives, upon reasonable advance notice
and during normal business hours, such access to the books and records of Seller (and, prior to the Closing, the Entities) and the employees and other service providers (including accountants and other advisors) to Seller (and, prior to the Closing,
the Entities), including work papers, schedules, memoranda and other documents, as may be reasonably requested by Purchaser in connection with the review of the Estimated Closing Statement; provided that such access will be subject to the
limitations described in the penultimate sentence of Section 8.1(a). From and after Closing, Purchaser will provide AI Brazil, Parent and Seller and their respective Representatives, upon reasonable advance notice and
during normal business hours, such access to the books and records of the Entities and the employees and other service providers (including accountants and other advisors) to the Entities, including work papers, schedules, memoranda and other
documents, as may be reasonably requested by Parent in connection with Parent’s or Seller’s review of the Closing Statement; provided that such access will be subject to the limitations described in the penultimate sentence of
Section 8.1(a) (it being understood that, for purposes of this proviso, all references to Parent and Seller in such sentence shall be deemed to refer to Purchaser). 

(g) Following the determination of the Final Closing Statement: 

(i) (A) if the Final Purchase Price exceeds the Estimated Purchase Price, then Purchaser will pay (1) to AI Brazil an amount equal
to such excess multiplied by the AI Brazil Percentage, and (2) to NIIH an amount equal to the remaining amount of such excess, or (B) if the Estimated Purchase Price exceeds the Final Purchase Price, then (1) AI Brazil will pay
to Purchaser an amount equal to such excess multiplied by the AI Brazil Percentage, and (2) NIIH will pay to Purchaser the remaining amount of such excess; 

(ii) (A) if the Estimated Unpaid Transaction Expenses exceed the Final Unpaid Transaction Expenses, then Purchaser shall pay to NIIH the
amount of such excess, or (B) if the Final Unpaid Transaction Expenses exceed the Estimated Unpaid Transaction Expenses, then NIIH shall pay to Purchaser the amount of such excess; and 

(iii) (A) if the Final Accrued Tax Contingencies Adjustment exceeds the Estimated Accrued Tax Contingencies Adjustment, then Purchaser
shall pay to NIIH the amount of such excess, or (B) if the Estimated Accrued Tax Contingencies Adjustment exceeds the Final Accrued Tax Contingencies Adjustment, then NIIH shall pay to Purchaser the amount of such excess. 

The Party that is required to make a payment pursuant to this Section 2.4(g) will make such payment within two Business Days after
the determination of the Final Closing Statement. Any payment under this Section 2.4(g) will be made in cash in Dollars, by wire transfer of immediately available funds to an account of the recipient designated in advance.
At Purchaser’s option and in its sole discretion, any amount owed to Purchaser by NIIH pursuant to this Section 2.4(g) may be recovered from the Escrow Amount. 

  
 34 

 (h) Any amount paid pursuant to Section 2.4(g) will be treated as
an adjustment to the Final Purchase Price for Tax reporting purposes. 
 (i) Notwithstanding anything to the contrary contained in this
Agreement, in no event shall the calculation of the Final AI Brazil Payment be reduced for, or by reason of, any claim by Purchaser of any breach or purported breach by Parent, Seller or the Entities of any of their respective representations and
warranties or obligations under this Agreement, in the understanding that any reduction in the Final Purchase Price made pursuant to the third sentence of Section 2.4(a) shall be entirely allocated to, and borne by, Seller.

Purchaser; provided that Purchaser shall not waive such condition unless AI Brazil shall have breached or failed to perform any of its respective covenants or other agreements set forth in this Agreement which inaccuracy, breach or failure to
perform would give rise to the failure of any of the conditions set forth in Section 9.1(b) or Section 9.1(d) to be satisfied or AI Brazil is in breach of its obligations to make or is incapable of

 (d) by Parent, if any condition to the obligations of Seller set forth in
Section 9.2 or Section 9.3 has become incapable of being satisfied by the Termination Date, other than as a result of a breach by Seller of any of its representations, warranties, covenants or

 (e) by Purchaser, if (i) there has been an

(i) each of the Parties will be relieved of its duties and obligations arising under this Agreement after the date of such termination, and (ii) subject to Section 3.6(b) such termination will be without liability
to Purchaser, Parent, Seller or AI Brazil; provided, however, that the provisions of Section 3.5, this Section 3.6, Section 8.9 and ARTICLE 13 (other
than Section 13.2) and, to the extent necessary to effectuate the foregoing enumerated provisions, ARTICLE 1, will survive any such termination and will be enforceable hereunder; provided, further, that
nothing in this Section 3.6 will be deemed to release any Party from liability for any Intentional Breach of its obligations under this Agreement arising prior to such termination; provided, further, that all confidential
information received by Purchaser with respect to Parent, Seller, AI Brazil and the Entities or any of their Affiliates, and any of their respective businesses, will be treated in accordance with the Confidentiality Agreements, which will remain in
full force and effect in accordance with their terms notwithstanding the termination of this Agreement. Notwithstanding anything in this Agreement to the contrary, AI Brazil will be relieved of its duties and obligations arising under this Agreement
after the date of such termination, without liability to Purchaser, Parent or Seller, other than any liability for any Intentional Breach of its obligations under this Agreement arising prior to such termination. 

(b) Parent will pay, or cause to be paid, to Purchaser by wire transfer of immediately available funds an amount equal to $25,000,000 (the
“Company Break-Up Fee”) if this Agreement is terminated: 
 (i) by Parent pursuant
to Section 3.4(i) (such payment to be made before or concurrently with such termination and, in the absence of such payment, any such purported termination will be invalid); 

(ii) by Purchaser pursuant to Section 3.4(j) (such payment to be made within two Business Days of such termination);
or 

  
 39 

 (iii) pursuant to Section 3.4(a),
Section 3.4(e) or Section 3.4(h) and, (A) after the date of this Agreement and prior to such termination any Person makes an Acquisition Proposal and (B) at any time on or prior to the
twelve-month anniversary of such termination, Parent or any of its Subsidiaries enters into a definitive agreement with respect to, or consummates, a transaction contemplated by an Acquisition Proposal (provided that, solely for purposes of
this Section 3.6(b)(iii), 50% shall replace 20% in the definition of Parent Takeover Proposal) (such payment to be made on the same day as the earlier of the entry into a definitive agreement and consummation of such a
transaction). 
 (c) If this Agreement is terminated by Parent pursuant to Section 3.4(h), then Parent shall pay or
cause to be paid to Purchaser an amount equal to the documented out-of-pocket expenses of Purchaser and its Affiliates incurred in connection with this Agreement and the
transactions contemplated hereby (such payment to be made within five Business Days of such termination), up to $2,000,000. The amount of any expenses reimbursed to Purchaser pursuant to this Section 3.6(c) shall be
credited against any future payment of the Company Break-Up Fee, if payable, pursuant to Section 3.6(b)(iii). 

(d) Notwithstanding anything in this Agreement to the contrary, Parent will not be required to pay the other Party the amount due pursuant to
Section 3.6(b) more than once. The Parties acknowledge and agree that the Company Break-Up Fee constitutes liquidated damages and is not a penalty and will be the sole and exclusive
remedy, including on account of punitive damages, for recovery by Purchaser, in the event of the termination of this Agreement by Parent pursuant to Section 3.4(i) or by Purchaser pursuant to
Section 3.4(j) (in the case where Purchaser is paid the Company Break-Up Fee pursuant to Section 3.6(b)). Upon payment of the Company
Break-Up Fee, Parent, Seller, the Company and AI Brazil and each of their respective Representatives and Affiliates will be fully released and discharged from any liability under or resulting from this
Agreement, and neither Purchaser, nor Parent, as applicable, nor any other Person will have any other remedy or cause of action under or relating to this Agreement or any applicable Law, including for reimbursement of expenses or otherwise;
provided that payment of the Company Break-Up Fee shall not release Seller, Parent or AI Brazil from liability for any Intentional Breach of its obligations hereunder arising prior to such payment. For
the avoidance of doubt, termination of this Agreement shall not relieve Parent, Seller or their respective Affiliates from any liability or obligation under the Nextel Holdings SHA. 

ARTICLE 4. REPRESENTATIONS AND WARRANTIES OF NIIH AND PARENT 

Except as set forth in the disclosure schedule delivered by NIIH and Parent to Purchaser concurrently with the execution of this Agreement
(each section of which qualifies the correspondingly numbered and lettered Section of this ARTICLE 4 or ARTICLE 6, as applicable, and any other Section of this ARTICLE 4 or ARTICLE 6 to the extent the responsiveness of
the relevant disclosure to such other Section is reasonably apparent on its face) (the “Company Disclosure Schedule”), each of NIIH and Parent hereby represents and warrants to AI Brazil and Purchaser, as of the date of this
Agreement and as of the Closing Date, that: 

  
 40 

 4.1. Organization of NIIH and Parent. Each of NIIH and Parent is an entity duly
organized, validly existing and in good standing under the Laws of the jurisdiction of its organization and has the requisite power and authority to hold directly and indirectly stakes in Luxembourg and/or foreign undertakings or, as the case may
be, own, lease and operate its properties and to carry on its businesses as now conducted. 
 4.2. Authorization of Agreement. Each of
NIIH and Parent has the requisite power and authority to execute and deliver this Agreement and each other agreement, document or instrument contemplated hereby or thereby to which it is a party (the “Ancillary Agreements”) and,
subject to the receipt of the Parent Stockholder Approval, to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and each Ancillary Agreement and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all requisite corporate action on the part of NIIH and Parent, subject to receipt of the Parent Stockholder Approval. The Parent Board, at a meeting duly called and held, has unanimously
(i) determined that this Agreement and the transactions contemplated hereby are fair to and in the best interests of Parent and the Parent Stockholders, (ii) approved and declared advisable the execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby, and (iii) resolved to recommend that the Parent Stockholders vote in favor of authorizing the transactions contemplated by this Agreement (such recommendation, the
“Parent Board Recommendation”), and directed that such matter be submitted for consideration by the Parent Stockholders at the Parent Stockholders Meeting. This Agreement and each Ancillary Agreement has been duly and validly

 51 

 
and function in accordance with their applicable specifications in all material respects and perform the functions necessary to effectively carry on the Entities’ businesses as currently
conducted. There have been (i) in the previous five years, no failures, defects, bugs, viruses or other causes for substandard performance of any IT Systems which have caused any material disruption to the business of any Entity, and

have been no losses, thefts, misuses or inadvertent disclosures thereof or any unauthorized access thereto that would reasonably be expected to be material to the business of any Entity or result in an obligation to notify any Person or Governmental
Authority. No Entity has made or been required to make any notification with respect to the foregoing to any Person or Governmental Authority. Except for disclosures of information required or permitted by applicable Law or authorized by the
individual who is the subject of the PII (when such authorization is a valid legal basis for disclosure), the Entities have not shared, sold, rented or otherwise made available to any third Person any PII. As of the date of this Agreement, there is
not and has not been any written complaint to, or Legal Proceeding against, the Entities by any Person or Governmental Authority with respect to the collection, storage, processing, use, transfer, disposal or disclosure of PII, or any other Action

8.1. Access to Information. (a) From the date of this Agreement until the Closing Date or earlier termination of this Agreement,
Purchaser will be entitled, through its officers, employees and other Representatives (including its legal advisors and accountants), to make such investigation of the properties, businesses and operations of the Entities and such examination of the
books and records of the Entities as it reasonably requests and to make extracts and copies of such books and records. Any such investigation or examination, and all communications with any Entity and their respective Representatives pursuant to
this Section 8.1, will be coordinated through representatives designated by Seller. NIIH will cause the officers, employees, consultants, agents, accountants, attorneys and other Representatives of the Entities to cooperate
with the reasonable requests of Purchaser and its Representatives in connection with such investigation and examination, and Purchaser and its Representatives will cooperate with the Entities and their respective Representatives and will use its
reasonable efforts to minimize any disruption to the Entities’ business. No such investigation or examination will be permitted to the extent that it would require any Entity to disclose information regarding any bids, the identity of any
bidder, confidentiality or non-disclosure agreements, letters of intent, expressions of interest or other proposals received, in each case prior to the date of this Agreement, in connection with transactions
comparable to those contemplated by this Agreement or any information or analysis relating to any such communications. Notwithstanding anything to the contrary in this Section 8.1, (i) any such investigation and examination
will be conducted upon reasonable notice and under reasonable circumstances during regular business hours and will be subject to restrictions under applicable Law and (ii) none of Parent, Seller, AI Brazil or any Entity will be required to

confidentiality obligations to which Parent, Seller, AI Brazil or any Entity is bound; provided that Parent, Seller, the applicable Entity or, to the extent related to AI Brazil’s interest in the Entities, AI Brazil, shall use
commercially reasonable efforts to permit such inspection or provide such information in a manner that would not result in the waiver of such privilege or violate such confidentiality obligations, including, in the case of clause (B), by obtaining
the consent of such third party if so requested by Purchaser. Nothing contained herein is intended to modify or terminate the Confidentiality Agreements, which will remain in full force and effect and applicable to Evaluation Material (as defined in

provided that, to the extent a relevant Governmental Authority requests information of AI Brazil or its Affiliates that is more burdensome than the information of AI Brazil or its Affiliates provided in connection with AI Brazil’s

advance from the source of the materials. 
 (b) Each of Purchaser, Parent, Seller and AI Brazil will use its reasonable best efforts to take
such action as may be required to obtain the Regulatory Approval (excluding the Antitrust Approval, which is subject to the terms of Section 8.5), including using their reasonable best efforts to finalize, prior to the
Closing, any Condition to a Governmental Authority’s granting of the Regulatory Approval, as promptly as reasonably practicable after the execution of this Agreement, and to avoid the entry of, or to effect the dissolution of, any Order in any
Legal Proceeding that would otherwise have the effect of preventing or materially delaying the consummation of the transactions contemplated by this Agreement; provided that nothing in this Section 8.4 or any other
provision of this Agreement shall require, or be construed to require, Purchaser or AI Brazil, or any of their respective Affiliates or any of the Entities to (and Parent, Seller and AI Brazil shall not, and Parent and Seller shall cause the

Affiliates’ ability to conduct their respective businesses or own any capital stock or assets or license any spectrum, or to acquire, hold, operate or exercise full rights of ownership of any businesses or assets, including those to be acquired
pursuant to this Agreement, in the case of this clause (i), to the extent any Condition described in the foregoing sub-clauses (A) through (F) would constitute a Burdensome Condition, (ii) pay any
amounts in connection with seeking or obtaining any required actions, approvals or waivers from any Governmental Authority in order to consummate the transactions contemplated by this Agreement (excluding any mandatory filing fees and costs and
expenses of counsel and other advisors), or (iii) litigate or participate in the litigation of any Legal Proceeding, whether judicial or administrative, with any Governmental Authority to contest, avoid entry of, or to have vacated, lifted,
reversed or overturned any Order that would prohibit, prevent or restrict the consummation of the transactions contemplated by this Agreement.

whether or not the Parties (other than AI Brazil) litigate with any Governmental Authority to contest or resist any Legal Proceeding challenging any transaction contemplated by this Agreement, or to have vacated, lifted, reversed or overturned any
Order that would prohibit, prevent or restrict the consummation of the transactions contemplated by this Agreement.

of them or any of their respective Affiliates under the Antitrust Statutes with respect to the transactions contemplated hereby (including, as required, the submission of this Agreement, the Ancillary Agreements, or any other document related to the
transactions contemplated hereby to the Brazilian Antitrust Authority) as promptly as practicable after the date of this Agreement. Purchaser, Parent and Seller will (i) comply at the earliest practicable date with any request under any

Authority under any Antitrust Statutes with respect to any such filing or any such transaction and (iii) use their respective reasonable best efforts to furnish all information required for any application or other filing to be made pursuant to
any applicable Law in connection with the transactions contemplated by this Agreement. AI Brazil will use reasonable best efforts to cooperate with the reasonable requests of Parent and Seller, at the sole cost and expense of such requesting Party,
to provide such information regarding AI Brazil as shall be required for any application or other filing to be made pursuant to any applicable Law in connection with the transactions contemplated by this Agreement; provided that, to the
extent a relevant Governmental Authority requests information of AI Brazil or its Affiliates that is more burdensome than the information of AI Brazil or its Affiliates provided in connection with AI Brazil’s investment in Nextel Holdings, the
Parties shall reasonably cooperate to limit the scope of such information request such that AI Brazil and its Affiliates are not required to provide more information than they were required to provide in connection with AI Brazil’s investment
in Nextel Holdings; 

  
 75 

 
provided, further, that if the Parties are unable to limit the scope of such information request in a timely manner, AI Brazil and its Affiliates shall use commercially reasonable

material oral communication with, and provide copies of material written communications with, any Governmental Authority regarding any such filing or application. Neither Purchaser, on the one hand, nor any of Parent, Seller or AI Brazil, on the
other hand, will independently participate, or permit any of its Affiliates or advisors to participate, in any formal meeting with any Governmental Authority in respect of any such filings, investigation, or other inquiry without giving Parent (in
the case of Purchaser’s participation in any such meeting) or Purchaser (in the case of Parent’s, Seller’s or AI Brazil’s participation) prior notice of the meeting and, to the extent permitted by such Governmental Authority, the
opportunity to attend and participate. Subject to applicable Law and Section 8.5(b), the Parties will consult and cooperate with one another in connection with any analyses, appearances, presentations, memoranda, briefs,
arguments, opinions and proposals made or submitted by or on behalf of any Party relating to proceedings under the Antitrust Statutes. Each Party may, as each deems advisable and necessary, reasonably designate any competitively sensitive material
provided to the other Parties under this Section 8.5 as “outside counsel only.” Such materials and the information contained therein will be given only to the outside legal counsel of the recipient and will not be
disclosed by such outside counsel to employees, officers or directors of the recipient, unless express written permission is obtained in advance from the source of the materials. 

(b) The Parties agree that Purchaser, on behalf of the Parties, will control and lead all communications, strategy and litigation matters
relating to, and the process of obtaining, the Antitrust Approval, and accordingly will be responsible for (i) leading any interaction with the Brazilian Antitrust Authority, (ii) controlling the filing of the Agreement and any other
document before the Brazilian Antitrust Authority regarding the Antitrust Approval, and the filling and submission of any other document or information required by the Brazilian Antitrust Authority, and (iii) preparing all drafts of any
submissions or material communications with the competent Governmental Authority in connection with the Antitrust Statutes; provided that (A) Purchaser will provide such drafts to Parent in a timely manner, will allow Parent reasonable
time to review and comment on such drafts, and will take into account any reasonable comments from Parent in connection with any such submissions or material communications and (B) to the extent that any such drafts include information relating
to AI Brazil or its Affiliates, Purchaser will provide such drafts to AI Brazil in a timely manner to allow AI Brazil reasonable time to review and comment on, and will take into account any reasonable comments from AI Brazil with respect to, such
information relating to AI Brazil or its Affiliates in any such submissions or material communications. 
 (c) Each of Purchaser, Parent and
Seller will use reasonable best efforts to resolve (and AI Brazil will reasonably cooperate with such efforts to resolve) such objections, if any, as may be asserted by the Brazilian Antitrust Authority or any other Governmental Authority under any
Antitrust Statutes with respect to the 

  
 76 

 
transactions contemplated by this Agreement, to finalize, prior to the Closing, any Condition to any Governmental Authority’s approval of the transactions contemplated by this Agreement
under the Antitrust Statutes, and to take promptly any and all steps necessary to avoid or eliminate each and every impediment under any Antitrust Statute that may be asserted by any Governmental Authority so as to enable the Parties to close the
transactions contemplated by this Agreement as expeditiously as possible; provided that nothing in this Section 8.5 or any other provision of this Agreement shall require, or be construed to require, Purchaser or AI
Brazil, or any of their respective Affiliates or any of the Entities to (and Parent, Seller and AI Brazil shall not, and Parent and Seller shall cause the Entities not to, without the prior written consent of Purchaser, or AI Brazil in the case of
any such limitations applicable to it or its Affiliates), (i) propose, negotiate, offer to commit, effect or accept, by consent decree, hold separate Order or otherwise, (A) the license, sale, divestiture, disposition or transfer of any portion
of its capital stock, assets, spectrum, licenses, customers, properties or businesses, (B) the discontinuation of any product or service offering, (C) the termination of existing relationships, contractual rights or obligations,
(D) the licensing or otherwise making available to any Person any technology, software or other intellectual property, (E) any obligation or commitment (to any Governmental Authority or otherwise) regarding its future operations or
investments or (F) the imposition of any other limitation on, or prohibition of, its and its Affiliates’ ability to conduct their respective businesses or own any capital stock or assets or license any spectrum, or to acquire, hold,
operate or exercise full rights of ownership of any businesses or assets, including those to be acquired pursuant to this Agreement, in the case of this clause (i), to the extent any Condition described in the foregoing sub-clauses (A) through (F) would constitute a Burdensome Condition, (ii) pay any amounts in connection with seeking or obtaining any required actions, approvals or waivers from any Governmental Authority
in order to consummate the transactions contemplated by this Agreement (excluding any mandatory filing fees and costs and expenses of counsel and other advisors), or (iii) litigate or participate in the litigation of any Legal Proceeding,
whether judicial or administrative, with any Governmental Authority to contest, avoid entry of, or to have vacated, lifted, reversed or overturned any Order that would prohibit, prevent or restrict the consummation of the transactions contemplated
by this Agreement. The Parties agree that Purchaser shall have the unilateral right to determine whether or not Parent, Seller and Purchaser litigate with any Governmental Authority to contest or resist any Legal Proceeding challenging any
transaction contemplated by this Agreement, or to have vacated, lifted, reversed or overturned any Order that would prohibit, prevent or restrict the consummation of the transactions contemplated by this Agreement. 

(d) Purchaser, on the one hand, and Parent, on the other hand, will each pay 50% of all filing or administrative fees related to the Antitrust
Approval. 
 8.6. Regulatory Compliance. Without limiting Section 8.2(b), during the period from the date of
this Agreement until the Closing Date or earlier termination of this Agreement, Parent and Seller shall (and AI Brazil shall reasonably cooperate with Parent’s and Seller’s efforts), and Parent and Seller shall cause each of the Entities
to, (a) refrain from taking any action that would reasonably be expected to give any 

  
 77 

 
Governmental Authority with jurisdiction over Parent, Seller, AI Brazil or any of the Entities reasonable grounds to suspend, revoke or modify any Telecommunication License of the Entities in any
adverse manner (other than in any de minimis respect) and (b) use reasonable best efforts to renew the material Permits, Telecommunications Licenses of the Entities, including preparing and filing with the applicable Governmental
Authority all necessary applications in connection therewith as soon as reasonably practicable after the commencement of the period during which such applications may be made; provided that none of the Entities will apply for any Permit or
Telecommunications License (other than renewals or replacements of the existing Telecommunication Licenses of the Entities) the receipt of which would, individually or in the aggregate, reasonably be expected to prevent, materially impair or
materially delay consummation of the transactions contemplated by this Agreement. 
 8.7. Further Assurances. (a) Subject to (and
without limiting) the other provisions of this Agreement and any provisos or qualifications therein, each Party will use its reasonable best efforts to (i) take all actions necessary or appropriate to consummate the transactions contemplated by
this Agreement and (ii) to the extent reasonably within the control of such Party, cause the fulfillment at the earliest practicable date of all of the conditions to its respective obligations to consummate the transactions contemplated by this
Agreement. 
 (b) Purchaser will, and will cause the Company and any other Entities to, following the Closing Date, as the case may be, make
all fillings, submissions and registries before any and all Governmental Authorities, including the relevant Board of Trade, RFB or BACEN, as required by applicable Law, in order to reflect the sale and assignment of the Acquired Equity Interests,
and change of management of the Entities. Purchaser will ensure that initial filings and submissions are carried out within 10 Business Days from the Closing Date. Evidence of all such fillings, submissions, replacements, and registration will be
presented to Seller and AI Brazil promptly after conclusion thereof. 
 8.8. Notices of Certain Events; Transaction Litigation. 

(a) Parent shall notify Purchaser and AI Brazil as promptly as reasonably practicable of (i) any notice or other communication from any
Person to Parent, NIIH or the Entities alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, (ii) any notice or other material communication to Parent, Seller, AI
Brazil or the Entities from any Governmental Authority in connection with the transactions contemplated by this Agreement, (iii) any Action commenced or, to the Knowledge of the Company, threatened against Parent or its directors or officers
that is related to this Agreement or the transactions contemplated by this Agreement (any such Action, “Transaction Litigation”), and (iv) if it becomes aware of any event, change or effect following the date of this Agreement
which has resulted or is reasonably likely to result in the failure of any of the conditions set forth in Sections 9.1(a) through 9.1(e). In no event shall the delivery of any notice by a party pursuant to this
Section 8.8 limit or otherwise affect the respective rights, obligations, representations, warranties, covenants or agreements of the Parties or the conditions to the obligations of the parties under this Agreement. 

  
 78 

 (b) Parent shall keep Purchaser and AI Brazil reasonably informed regarding any Transaction
Litigation. Parent shall give Purchaser and AI Brazil the opportunity to participate, subject to Purchaser or AI Brazil, as applicable, entering into a customary joint defense agreement with Parent, in the defense, settlement, or entry into any
other agreement with respect to such Transaction Litigation, including the opportunity to review and comment on all filings or responses to be made in connection with any Transaction Litigation and Parent shall consider any such comments in good
faith. Each of Purchaser, AI Brazil and Parent will cooperate and consult with one another in connection with any Transaction Litigation. 

8.9. Publicity. The initial press release concerning this Agreement and the transactions contemplated hereby will be in substantially
the form previously agreed by the Parties. None of the Parties will issue any press release concerning this Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other Parties, which approval will not
be unreasonably withheld or delayed, unless disclosure or filing are otherwise required by applicable Law, provided, however, that the Party intending to make such release uses its reasonable best efforts consistent with such
applicable Law requirement to consult in advance with the other Parties with respect to the text thereof. 
 8.10. Preservation of
Records. Seller and Purchaser agree that each of them will preserve and keep the records held by it or their Affiliates relating to the Entities and their business for a period of at least seven years from the Closing Date (except as provided
below) and will make, upon reasonable notice and during regular business hours, such records and personnel available to the other and AI Brazil as may be reasonably required by such Party in connection with any insurance claims by, Legal Proceedings
or Tax audits against or governmental investigations of Seller or Purchaser or any of their Affiliates or in order to enable AI Brazil, Seller or Purchaser to prepare its financial statements and tax reporting or to comply with applicable Law or
their respective obligations under this Agreement and each other agreement, document or instrument contemplated hereby; provided, however, that (a) the access to such records will not unreasonably interfere with the business or
operations of Purchaser or Seller, as applicable, or any of their Affiliates, (b) the access to such records will not be permitted to the extent that it would require Purchaser or Seller, as applicable, or any of their Affiliates, to
(i) disclose information subject to attorney-client privilege or (ii) violate any confidentiality obligations to which Purchaser, Seller or AI Brazil, as applicable, or any of their Affiliates, is bound if the applicable Person shall have
used commercially reasonable efforts to obtain the consent of the applicable third party to grant access to such records, and (c) Seller or Purchaser, as applicable, will reimburse the other Party or Parties and their Affiliates for any
reasonable and documented out-of-pocket expenses incurred in connection with such access. If Seller or Purchaser, as the case may be, wishes to destroy such records
before the end of such seven-year period, such Party will first give 60 days prior written notice to the other and AI Brazil and such other Party or Parties will have the right at its or their option and expense, upon prior written notice given to
such Party within such 60-day period, to take possession of the records within 90 days after the date of such notice. 

  
 79 

 8.11. Trademark License Agreement. Prior to Closing, Parent and Nextel Brazil will
amend the Trademark Sublicense Agreement to expressly include a sublicense from Parent to Nextel Brazil under the following trademark applications in Brazil owned by the Trademark Licensor: Application Nos. 914688316, 914688340, 914688391,
914688405. For a period of at least 12 months after the Closing Date, Parent and NIIH will (a) maintain the Trademark License Agreement in full force and effect, (b) not amend, modify or otherwise waive any provision of the Trademark
License Agreement in any manner that would adversely affect the rights of the Entities under the Trademark Sublicense Agreement and (c) otherwise permit the Entities to continue to use the trademarks licensed pursuant to the Trademark
Sublicense Agreement under the terms thereof during such 12-month period. Neither Purchaser nor any of the Entities shall have any obligation to pay any royalties, fees, expenses or any other amounts to Parent
or any other Person for use of such trademarks during such 12-month period. 
 8.12. Preparation
of Proxy Statement; Stockholders Meeting. (a) As promptly as reasonably practicable (and in any event no later than 30 days) following the date of this Agreement, Parent will prepare and cause to be filed with the SEC in preliminary form a proxy
statement to be sent to the Parent Stockholders in connection with the Parent Stockholders Meeting (as amended or supplemented, the “Proxy Statement”). Purchaser and Parent will cooperate with each other in the preparation of the
Proxy Statement. Without limiting the generality of the foregoing, (i) Parent will provide Purchaser and AI Brazil with a reasonable opportunity to review and comment (in the case of AI Brazil, with respect to information relating to AI Brazil)
on the Proxy Statement and (ii) upon Parent’s request, Purchaser and AI Brazil will promptly furnish to Parent the information relating to it required by the Exchange Act to be set forth in the Proxy Statement. Parent will cause the Proxy
Statement to comply as to form with the applicable requirements of (A) the Exchange Act and (B) the rules and regulations of The NASDAQ Stock Market. 

(b) Each of Parent, NIIH, AI Brazil and Purchaser agree to correct any information provided by it for use in the Proxy Statement if and to the
extent such information shall have become false or misleading. Parent will promptly notify Purchaser and AI Brazil of the receipt of any comments from or other correspondence with the SEC or its staff with respect to the Proxy Statement and any
request by the SEC or its staff for any amendment to the Proxy Statement or for additional information (and promptly deliver a copy of such comments, correspondence or request to Purchaser and AI Brazil). Parent will respond as promptly as
reasonably practicable to any such comments from the SEC or its staff and shall use its reasonable best efforts to cause the Proxy Statement to be cleared by the SEC as promptly as reasonably practicable. 

(c) Parent shall, as promptly as reasonably practicable (and in any event within 10 Business Days following the date on which the Proxy
Statement is cleared by the SEC), (i) establish a record date for and give notice of a meeting of its stockholders for the purpose of authorizing this Agreement and the transactions 

  
 80 

 
contemplated hereby (the “Parent Stockholders Meeting”), and (ii) mail the Proxy Statement to the holders of Parent Common Stock as of the record date established for the
Parent Stockholders Meeting. As promptly as reasonably practicable following the record date established for the Parent Stockholders Meeting, Parent, acting through the Parent Board, and in accordance with applicable Law, shall (A) duly call,
convene and hold the Parent Stockholders Meeting and (B) (1) subject to Section 8.13, include in the Proxy Statement the Parent Board Recommendation and (2) use its reasonable best efforts to obtain the necessary
approval of the transactions contemplated by this Agreement by the Parent Stockholders. Without limiting the generality of the foregoing, subject to termination of this Agreement by Parent pursuant to Section 3.4(i), Parent
agrees that its obligations pursuant to clause (A) of the foregoing sentence of this Section 8.12(c) will not be affected by the commencement, public proposal, public disclosure or communication to Seller, AI
Brazil or any other Person of any Acquisition Proposal or the occurrence of any Adverse Recommendation Change. 
 (d) Without the prior
written consent of Purchaser, Parent may only adjourn or postpone the Parent Stockholders Meeting if and to the extent the Parent Board or a duly authorized committee thereof determines, in good faith and after consultation with outside legal
counsel, that (i) Parent is required to postpone the meeting to ensure that any required supplement or amendment to the Proxy Statement is provided to the Parent Stockholders within a reasonable amount of time in advance of the Parent
Stockholders Meeting, (ii) there are insufficient shares of Parent common stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Parent Stockholders Meeting, (iii) it is necessary
to solicit additional proxies to obtain the Parent Stockholder Approval or (iv) such adjournment or postponement if required to comply with applicable statutory Law; provided that Parent may only postpone the meeting only once, and for a
period of not more than an aggregate of 15 Business Days. 
 (e) Except as set forth on Section 8.12(e) of the Company Disclosure
Schedule, the adoption of this Agreement will be the only matter (other than matters of procedure and matters required by applicable Law to be voted on by the Parent Stockholders in connection with the adoption of this Agreement) that Parent will
propose to be acted on by the Parent Stockholders at the Parent Stockholders meeting. 
 8.13. No Solicitation. (a) Except as
expressly permitted by this Section 8.13, from the date of this Agreement until the Closing Date or earlier termination of this Agreement, Parent and AI Brazil shall not, nor shall they authorize or permit any of their
Subsidiaries to, and shall use their reasonable best efforts to cause their and their respective Representatives not to, directly or indirectly (i) initiate, solicit or knowingly encourage or facilitate the making of any Acquisition Proposal or
any inquiry, proposal or request for information that may reasonably be expected to lead to an Acquisition Proposal, (ii) engage in negotiations or discussions with, or furnish any information concerning any of the Entities, NIIH or Parent to,
any third party relating to an Acquisition Proposal or any inquiry, proposal or request for information that may reasonably be expected to lead to an Acquisition Proposal (other than informing third parties of the existence of the provisions
contained in this Section 8.13), (iii) enter into 

  
 81 

 
any agreement or understanding with respect to an Acquisition Proposal, (iv) accept, approve, endorse or recommend, or submit to the Parent Stockholders, any Acquisition Proposal,
(v) take any action to exempt any Person (other than Purchaser and its Affiliates) from the provisions of Section 203 of the DGCL or any other state takeover statute or (vi) resolve or agree to do any of the foregoing. Parent and AI
Brazil shall, and shall cause their Affiliates and their and their Affiliates’ respective Representatives to (A) immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore
with respect to any Acquisition Proposal, or any inquiry or proposal that may reasonably be expected to lead to an Acquisition Proposal and (B) promptly cause to be returned or destroyed all confidential information provided by or on behalf of
Parent or AI Brazil or any of their Affiliates to any such Person. 
 (b) Notwithstanding Section 8.13(a), at any
time prior to the date that the Parent Stockholder Approval is obtained at the Parent Stockholders Meeting, in the event that Parent receives an unsolicited written Acquisition Proposal from a third party (which Acquisition Proposal was made after
the date of this Agreement and did not result from a breach of this Section 8.13), and if the board of directors of Parent determines in good faith, after consultation with Parent’s legal and financial advisors, that
such Acquisition Proposal constitutes, or is reasonably likely to result in, a Superior Proposal, then Parent, AI Brazil and their respective Representatives may, subject to compliance with this Section 8.13, (i) furnish,
pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with respect to Parent and its Subsidiaries to the Person or group of Persons who has made such Acquisition
Proposal (provided that any non-public information concerning Parent or any of its Subsidiaries that is provided to any Person given such access was previously provided, or is substantially concurrently
provided, to Purchaser or its Representatives) and (ii) engage in or otherwise participate in discussions or negotiations with the Person or group of Persons making such Acquisition Proposal and with AI Brazil and Parent (as applicable);
provided that Parent shall give written notice to Purchaser and AI Brazil after any such determination by the Parent board of directors and prior to taking any of the actions described in this Section 8.13(b) and
shall comply with the provisions of Sections 8.13(c) and 8.13(f). Other than in connection with the termination of this Agreement pursuant to Section 3.4(i) or as required by applicable statutory Law,
Parent shall not publicly announce the receipt of any Acquisition Proposal or any negotiations or discussions in connection with any Acquisition Proposal or otherwise publicly comment on any Acquisition Proposal (other than to publicly reaffirm the
Parent Board Recommendation or to recommend against any such Acquisition Proposal, in each case in accordance with Section 8.13(c)). 

(c) Except as otherwise provided by Section 8.13(d) or Section 8.13(e), neither the Parent
Board nor any committee thereof will (i) (A) withdraw (or qualify or modify in any manner adverse to Purchaser), or publicly propose to withdraw (or so qualify or modify), the Parent Board Recommendation, (B) fail to include the Parent
Board Recommendation in the Proxy Statement, (C) take any action to exempt any Person (other than Purchaser and its Affiliates) from the provisions of Section 203 of the DGCL or any other state takeover statute, (D) with respect to
any publicly announced Acquisition Proposal, fail to publicly reaffirm the Parent Board Recommendation within 

  
 82 

 
three Business Days after Purchaser so requests in writing, (E) if a tender or exchange offer for shares of Parent Common Stock is commenced, fail to recommend, in a
Solicitation/Recommendation Statement on Schedule 14D-9, against any such tender or exchange offer subject to Regulation 14D under the Exchange Act within three Business Days after commencement of such tender
or exchange offer, (F) approve, adopt or recommend any Acquisition Proposal or Alternative Acquisition Agreement, or propose publicly to approve, adopt or recommend, any Acquisition Proposal or Alternative Acquisition Agreement or
(G) publicly announce that an Acquisition Proposal constitutes a Superior Proposal (any action described in the foregoing clauses (A) through (G) being referred to as an “Adverse Recommendation Change”) or
(ii) allow Parent or any of its Subsidiaries to execute or enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement or other Contract (other than an Acceptable Confidentiality
Agreement pursuant to Section 8.13(b)) with any third party constituting or relating to, or that is intended to or would reasonably be expected to lead to, any Acquisition Proposal, or requiring, or reasonably expected to
cause, Parent, Seller or AI Brazil to abandon, terminate, delay or fail to consummate, or that would otherwise impede, interfere with or be inconsistent with, the transactions contemplated by this Agreement, or requiring, or reasonably expected to
cause, Parent to fail to comply with this Agreement (an “Alternative Acquisition Agreement”). 
 (d) Notwithstanding the
foregoing, at any time after the date hereof and prior to receipt of the Parent Stockholder Approval, in response to an unsolicited written Acquisition Proposal that was made after the date of this Agreement and that did not result from any breach
of this Section 8.13, the Parent Board may terminate this Agreement pursuant to Section 3.4(i) (including payment of the Company Break-Up Fee pursuant to
Section 3.6(b)) and cause Parent or any of its Subsidiaries to enter into a definitive agreement with respect to any Superior Proposal if the Parent Board has determined in good faith, after consultation with its financial
and legal advisors, that (i) the failure to do so would be a breach of the Parent Board’s fiduciary duties under applicable Law and (ii) such Acquisition Proposal constitutes a Superior Proposal; provided, however, that
(A) Parent has given Purchaser and AI Brazil at least five Business Days’ prior written notice that the Parent Board is prepared to accept a Superior Proposal, which notice must specify the material terms and conditions of such Superior
Proposal (including the identity of the Person making the proposal) and contemporaneously furnish a copy of the relevant acquisition agreement or other relevant transaction documents, (B) Parent has negotiated, and has caused its
Representatives to negotiate, in good faith with Purchaser during such notice period, to the extent Purchaser wishes to negotiate, to enable Purchaser to propose revisions to the terms of this Agreement such that it would cause such Superior
Proposal to no longer constitute a Superior Proposal, (C) Parent Board has met to consider any revised proposal by Purchaser and (D) prior to the expiration of such five-Business Day period, Purchaser does not make a proposal to adjust the
terms and conditions of this Agreement that the Parent Board determines in good faith (after consultation with its financial advisors and legal counsel) to be at least as favorable as the Superior Proposal after giving effect to, among other things,
the payment of the Company Break-Up Fee pursuant to Section 3.6(b). Any material change to the terms, facts and circumstances relating to the Superior Proposal will be deemed to be a
new Superior Proposal for purposes of this Section 8.13(d); provided that the time periods referred to in the foregoing clauses (A) through (C) shall be three Business Days instead of five Business Days. 

  
 83 

 (e) Notwithstanding anything in this Agreement to the contrary, other than in connection
with a Superior Proposal (which shall be subject to Section 8.13(d) and shall not be subject to this Section 8.13(e)), prior to obtaining the Parent Stockholder Approval, the Parent Board may, in
response to or as a result of an Intervening Event, take any action described in clause (A) or (B) of the definition of Adverse Recommendation Change, if (i) the Parent Board determines in good faith, after consultation with its outside
legal counsel, that the failure to take such action would be a breach of its fiduciary duties under applicable Law, (ii) Parent has notified Purchaser and AI Brazil in writing that it intends to effect such an Adverse Recommendation Change
pursuant to this Section 8.13(e) (which notice shall specify the facts and circumstances providing the basis of the Company Intervening Event in reasonable detail), (iii) for a period of five Business Days following
the notice delivered pursuant to the foregoing clause (ii), Parent and Parent’s relevant Representatives shall have discussed and negotiated in good faith (to the extent Purchaser desires to negotiate) with Purchaser and Purchaser’s
relevant Representatives any proposed modifications to the terms and conditions of this Agreement, and (iv) no earlier than the end of such five Business Day period, the Parent Board shall have determined in good faith, after consultation with
outside legal counsel, and after taking into account any proposal by Purchaser to amend or modify the terms of this Agreement offered by Parent in writing, that the failure to take such action would still be a breach of its fiduciary duties under
applicable Law. 
 (f) Parent shall promptly (and in any event, within 48 hours) advise Purchaser orally and in writing of the receipt of any
Acquisition Proposal, any request to engage in discussions or negotiations with respect to an Acquisition Proposal or any request for information that would reasonably be expected to relate to an Acquisition Proposal, and in connection with such
notice, provide to Purchaser the material terms and conditions of any such Acquisition Proposal (including the identity of the third party making any such Acquisition Proposal) and of any changes thereto. Parent shall promptly advise Purchaser
orally and in writing of the commencement of any discussions with any third party or its Representatives regarding any Acquisition Proposal by such third party. Parent shall keep Purchaser informed (orally and in writing) in all material respects on
a timely basis of the status and details (including, within 48 hours after the occurrence of any amendment, modification, material development or negotiation) of any such Acquisition Proposal or request, including promptly furnishing to Purchaser
copies of any written Acquisition Proposal, any other written materials that describe any such Acquisition Proposal, any material correspondence relating thereto, and draft documentation with respect to such Acquisition Proposal. 

  
 84 

 (g) Nothing contained in this Section 8.13 or in Section 8.9 or
Section 8.12 will prohibit Parent or the Parent Board from taking and disclosing to Parent Stockholders a position contemplated by Rule 14e-2(a) or Rule
14d-9 promulgated under the Exchange Act or from making any other disclosure to Parent Stockholders if, in the good faith judgment of the Parent Board after consultation with legal counsel, the failure so to
disclose would be a breach of its obligations under applicable Law; provided, however, that in no event will this Section 8.13(g) modify, or be construed to modify, the definition of Adverse Recommendation Change or otherwise affect the
obligations of Seller or Parent specified in Sections 8.13(d) and 8.13(f); provided, further, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated
by Section 14d-9(f) under the Exchange Act) will be deemed to be an Adverse Recommendation Change unless the Parent Board expressly reaffirms, upon written request of Purchaser, the Parent Board
Recommendation to the Parent Stockholders not less than three Business Days after such request, and in any event at least two Business Days prior to the Parent Stockholders Meeting. 

(h) Parent and Seller agree that any violations of the restrictions set forth in this Section 8.13 by their
respective Affiliates or by any of their or their Affiliates’ Representatives, shall be deemed to be a breach of this Agreement (including this Section 8.13) by Parent and Seller. 

8.14. [INTENTIONALLY OMITTED]. 

8.15. Intercompany Notes. Prior to the Closing, Parent shall not, and shall cause its applicable Subsidiaries not to, repay, capitalize
or discharge any of the Intercompany Obligations described on Section 8.15 of the Company Disclosure Schedule (the “Intercompany Notes”) and shall take any actions required to maintain the Intercompany Notes outstanding
pursuant to the existing terms of such Intercompany Notes in effect as of the date of this Agreement. Notwithstanding the foregoing sentence, (a) prior to Closing, Parent shall consider in good faith any request by Purchaser, delivered in
writing to Parent, to modify the terms of the Intercompany Notes (including by way of a capitalization of the principal and/or discharge of interest of any such Intercompany Notes) (a “Requested Notes Modification”) and (b) in
the event that Parent so agrees to modify any such Intercompany Notes as requested by Purchaser, (i) Parent shall, and shall cause its applicable Subsidiary to, use its reasonable best efforts to effect such requested changes and, in case of a
discharge of interest, (A) the amount of taxable revenues for corporate income tax purposes (IRPJ and CSLL) shall be offset against its tax losses of the current tax period, including but not limited to the amount of deductible tax losses of
foreign exchange variation resulting from any previous or simultaneous capitalization of principal of the Intercompany Notes, and (B) the amount of PIS/COFINS credits obtained as a result of a Discharge Tax Decision shall be used by the
applicable Brazilian Entity to offset PIS/COFINS due as a result of the discharge of interest, and the excess of PIS/COFINS credits shall not be used by such Brazilian Entity for any other purposes until Closing; and (ii) Purchaser shall
assume, and shall indemnify the Entities from, any and all Taxes arising from such Requested Notes Modification including with respect to any and all PIS/COFINS due in respect of any requested discharge of any such Intercompany Notes);
provided that, for the avoidance of doubt, the use of credits by the relevant Subsidiary for the offset of 

  
 85 

 
taxable revenues as described in items (A) and (B) of the preceding clause (i) above shall not be considered Taxes for purposes hereof; provided, further, that in the
event that Parent implements a Requested Notes Modification that directly results in (x) a reduction in Cash or (y) an increase in current liabilities for Taxes payable that have not been satisfied prior to the Adjustment Time, then
(x) the calculation of the Closing Indebtedness Adjustment will be reduced by an amount corresponding to such reduction in Cash or (y) the calculation of Closing Net Working Capital shall be increased by an amount corresponding to such
increase in Tax liability. From the date of this Agreement until the Closing Date, Parent and Seller will use their respective reasonable best efforts to (and Seller will cause the Entities to) obtain as promptly as reasonably practicable a final
and non-appealable Order from a Governmental Authority of competent jurisdiction recognizing that the applicable borrowers under the Intercompany Notes are entitled to the PIS/COFINS credits arising from the
PIS/COFINS Credits Claim (the “Discharge Tax Decision”). Parent shall cooperate with any reasonable requests of Purchaser with respect to information or actions related to the PIS/COFINS Credits Claim, Discharge Tax Decision and any
other act described in this Section 8.15. Except for the specific obligations set forth in this Section 8.15 and in ARTICLE 10, Parent, Seller and each of their Subsidiaries shall have no
other obligations with respect to the Intercompany Notes. 
 8.16. Termination of Related Party Contracts. Prior to or simultaneously
with the Closing, Parent, Seller and AI Brazil shall, and shall cause their applicable Subsidiaries to, terminate all Related Party Contracts and extinguish all Intercompany Obligations owed by any Entity to Seller or AI Brazil or any of their
respective Affiliates (other than the Entities) (for the avoidance of doubt, other than (i) the Intercompany Notes, the settlement of which shall be governed by Section 8.15 and (ii) the Trademark Sublicense
Agreement, which shall be governed by Section 8.11), without any further force or effect or survival of any provision thereunder, and without any cost, expense or Liability to any Entity or any of their post-Closing
Affiliates other than the payment of cash amounts taken into account in the calculation of Estimated Unpaid Transaction Expenses or otherwise paid at or prior to Closing. 

8.17. Union Actions. Prior to the Closing Date, Seller shall, and shall cause the applicable Entities to, fulfill all consultation,
bargaining and notification requirements to any union, works councils or other similar labor organization if required in connection with the negotiation and consummation of the transactions contemplated by this Agreement. 

8.18. Employee Communications. Except as is expressly required by the terms of this Agreement, from and after the date of this Agreement
and until the Closing Date, none of Parent, any of its Affiliates or any of their respective Representatives shall, without prior consultation with the Purchaser, send, distribute or otherwise make available written communications or other material
communications regarding the transactions contemplated by this Agreement, to any current or former employee of any Entity (other than the Chief Executive Officer of Nextel Brazil and his direct reports or directors and officers of any other Entity)
or other independent consultant employed by any Entity, including any post-Closing employment, compensation or benefits, except for communications that contain substantially the same information as contained in prior public communications made by
one or more parties to this Agreement in compliance with this Agreement.

 8.19. Pay-Off Cooperation. Seller shall, and
shall cause each of the Entities to, (a) provide copies of the Pay-Off Letters at least 20 Business Days prior to Closing and (b) if requested by Purchaser in writing, use commercially reasonable
efforts to take any actions and provide any cooperation reasonably requested by Purchaser in connection with the payment of the Pay-Off Amount or obtaining each of the
Pay-Off Letters. 
 8.20. Parent Convertible Notes. 

(a) The Parties expressly acknowledge and agree that none of Parent’s obligations under the Parent Convertible Notes will be assumed or
guaranteed by Purchaser, the Entities or any Affiliate thereof. Parent may, in its reasonable discretion, take actions to amend the Indenture prior to the Closing to eliminate the obligations contemplated under Article 11 of the Indenture (and, in
Parent’s reasonable discretion, to delete or modify other provisions of the Indenture in a manner not adverse to Purchaser or the Entities or that would not impede or delay the Closing). Parent shall keep Purchaser informed with respect to the
status of the actions taken pursuant to the foregoing. 
 (b) In the event that the Indenture has not been amended in accordance with
Section 8.20(a), Parent shall elect to satisfy its obligations under Section 11.01(a) of the Indenture by causing an amount in cash equal to the Convertible Notes Escrow Amount to be deposited into an escrow account
pursuant to Section 11.04 of the Indenture (an “Escrow Election”), and shall deliver written notice of such Escrow Election to the trustee no later than fifteen business days prior to the anticipated Closing Date. In the event
of an Escrow Election, (i) Parent shall negotiate in good faith, and enter into, an escrow agreement with the trustee and an escrow agent as promptly as reasonably practicable and in any event prior to the Closing Date, which escrow agreement
shall (A) establish an escrow account to receive an amount in cash equal to the Convertible Notes Escrow Amount and (B) grant the trustee, for the benefit of the holders of the Parent Convertible Notes, the trustee and the escrow agent, a
first priority security interest in the funds in the escrow account to secure Parent’s obligations under the Indenture, (ii) unless Parent has previously caused an amount in cash equal to the Convertible Notes Escrow Amount to be deposited
into the escrow account pursuant to Section 11.04 of the Indenture, Purchaser will deduct an amount in cash equal to the Convertible Notes Escrow Amount from the amount payable to NIIH pursuant to Section 2.3(a) and
deposit such amount with the escrow agent pursuant to the escrow agreement contemplated in this Section 8.20(b), and (iii) Parent shall otherwise comply with Section 11.04 and the other terms of Article 11 of the
Indenture with respect to such Escrow Election and the transactions contemplated by this Agreement. 

  
 87 

 8.21. Right of First Refusal. By its execution and delivery of this Agreement, and
without prejudice to any rights it may have following any termination of this Agreement, and subject to the proviso below, AI Brazil, on behalf of itself and its Affiliates, hereby waives any and all rights of first refusal under Section 2.5 or
Section 2.6 of the Nextel Holdings SHA in connection with this Agreement and the consummation of the transactions contemplated hereby; provided, however, that if (i) Purchaser, Seller and Parent amend or modify this Agreement
pursuant to Section 13.5(b) in any material respect after the date hereof and AI Brazil is not a party to such amendment or modification or (ii) Parent or Seller provides notice that it intends to accept a Superior
Proposal, AI Brazil may revoke the foregoing waiver. 
 8.22. AI Brazil Cooperation. AI Brazil expressly acknowledges and agrees that
it shall not exercise any rights or privileges in connection with its ownership of the AI Brazil Shares, including its rights under the Nextel Holdings SHA, in a manner that would be inconsistent with AI Brazil’s obligations under this
Agreement to consummate the transactions contemplated by this Agreement. For the avoidance of doubt, nothing in this Section 8.22 shall be deemed to restrict AI Brazil from exercising its rights with respect to any
transaction, occurrence or event, including with respect to an NII Internal Reorganization, Intercompany Notes Modification, Tax Claim or change in Tax reporting position, to the extent such exercise is not inconsistent with AI Brazil’s
obligations under Sections 2.1, 3.2 (as to the deliveries of the items thereunder), 8.1(a), 8.2(d), 8.3, 8.4, 8.5, 8.6, 8.7(a) (as to actions that, to the knowledge of AI Brazil, AI
Brazil is required to undertake pursuant thereto), 8.12, 8.13, 8.16 and 8.23 of this Agreement to consummate the transactions contemplated by this Agreement. 

8.23. Confidentiality. From and after the Closing, Seller, AI Brazil and Parent shall not, and shall cause their Affiliates not to,
directly or indirectly, disclose, reveal, divulge, or communicate to any Person (other than authorized officers, directors, employees, and other Representatives of Purchaser or its Subsidiaries), or use or otherwise exploit for their own benefit or
for the benefit of anyone other than Purchaser or its Subsidiaries, any confidential or proprietary information of the Entities; provided, however, that Parent, Seller and AI Brazil may disclose any such information to their
Representatives who have a need to know such information and who have agreed to be bound by confidentiality obligations with respect to such information that are no less restrictive than those contained in this Agreement. Parent, Seller, AI Brazil
and their Affiliates will not have any obligation to keep confidential any confidential information if and to the extent disclosure thereof is required by applicable Law or any Governmental Authority; provided that in the event disclosure is
required by applicable Law or Governmental Authority, Seller and AI Brazil will provide Purchaser with prompt notice of such requirement prior to making any disclosure and cooperate with Purchaser so that Purchaser may, at its own cost and expense,
seek to limit such disclosure or obtain an appropriate protective order.

Closing Date (except for any representation and warranty expressly made as of a specified date, in which case such representation and warranty shall be true and correct as of such date), except where the failure to be so true and correct would not

condition to be satisfied. 
 ARTICLE 10. PARENT INDEMNIFICATION 

10.1. Survival. 
 (a) The
representations and warranties contained in ARTICLE 4 and ARTICLE 6 (together with any right to assert any claim with respect thereto) will survive the Closing and will remain in full force and effect until 5:00 p.m., New York City
time, on the date that is the 18-month anniversary of the Closing Date, at which time they will terminate, except that the Seller Fundamental Representations will survive the Closing (together with any right to assert any claim with respect thereto)
and remain in full force and effect indefinitely. The covenants and agreements contained in this Agreement that are to be performed in full on or prior to the Closing will survive the Closing (together with any right to assert any claim with respect
thereto) and will thereafter terminate at 5:00 p.m., New York City time, on the date that is the 18-month anniversary of the Closing Date. The covenants and agreements that are to be performed in whole or in part after the Closing will survive the
Closing (together with any right to assert any claim with respect thereto) until performed in accordance with their terms. 

  
 91 

 (b) Notwithstanding Section 10.1(a), if Parent voluntarily adopts,
enters into or becomes subject to any plan of complete liquidation or dissolution, or involuntarily becomes subject to an order of liquidation, dissolution or winding up (any such event, a “Parent Liquidation Event”), then the
representations, warranties, covenants and agreements set forth in ARTICLE 4 and ARTICLE 6 of this Agreement will terminate on the earlier of (a) the survival date for such representation, warranty, covenant or agreement provided
in Section 10.1(a) and (b) the expiration of the period during which Persons having a claim against Parent may notify Parent of such claims in connection with such Parent Liquidation Event (which Parent acknowledges
and agrees shall in no event be earlier than the 18-month anniversary of the Closing Date). Parent shall provide express written notice to Purchaser of the date of such expiration described in clause
(b) of the foregoing sentence not later than 180 days prior to its occurrence. The last day on which a representation and warranty, covenant or agreement survives pursuant to this Section 10.1 is referred to herein as
the “Limitation Date” with respect to such representation and warranty, covenant or agreement. No claim for indemnification pursuant to this ARTICLE 10 may be brought following the applicable Limitation Date; provided,
however, that if a Third Party Claim Notice or a Direct Claim Notice has been given to the Indemnifying Party on or prior to the applicable Limitation Date, the applicable claim or claims set forth in such notice will survive until
satisfaction or other resolution thereof, and may be amended after the date of such notice (including, for the avoidance of doubt, after the applicable Limitation Date) to allow for adjusted Damages based on the facts and circumstances giving rise
to such claim. In the event that (A) a Parent Liquidation Event has occurred and (B) an executive officer of Parent certifies to Purchaser in writing that the effective date for such Parent Liquidation Event will occur within six months of
the delivery of such certificate, the Parties agree to submit any unresolved claims for indemnification under this ARTICLE 10 to arbitration in accordance with Section 13.2. 

10.2. Indemnification by Parent. Subject to the limitations set forth in this ARTICLE 10 and elsewhere in this Agreement, from
and after the Closing, Parent will indemnify, defend and hold harmless Purchaser and its Affiliates (including the Entities) and their respective officers and directors (collectively, the “Purchaser Indemnitees”) from and against
any and all demands, claims, actions or causes of action, assessments, losses, diminution in value, damages (including consequential damages, to the extent reasonably foreseeable), liabilities, Taxes, costs and expenses, including interest,
penalties and attorneys’ fees and expenses (“Damages”) that a Purchaser Indemnitee actually suffers resulting from, arising out of or incurred in connection with: (a) any failure of any representation or warranty in
ARTICLE 4 or ARTICLE 6 to be true and correct as of the date of this Agreement or as of the Closing Date as if given as of such date (except to the extent that such representation and warranty speaks only as of a particular date, in
which case, as of such date), (b) any nonfulfillment, violation or breach of any covenant or agreement made by Seller or Parent in this Agreement, (c) the NII Internal Reorganization, (d) any Intercompany Notes Modification,
provided that this clause (d) shall not apply with respect to Taxes that arise out of or are incurred in connection with actions taken by Parent or its applicable Subsidiary at the express written request of Purchaser in accordance with
Section 8.15 or (e) any nonfulfillment, violation or breach of Parent or any of its Affiliates of the Indenture. For the purposes of 

  
 92 

 
this ARTICLE 10, with respect to any representation or warranty that is limited or qualified by any materiality or Seller Material Adverse Effect qualification or any similar
qualification, the occurrence of any failure of such representation or warranty to be true and correct, and the amount of Damages subject to indemnification hereunder, will be determined as if any such qualifications were not contained therein;
provided, however, that this sentence will not apply to (i) any such qualifications contained in the definition of any defined term used herein, or (ii) the representation and warranty set forth in
Section 6.20(b). 
 10.3. Tax Indemnification. From and after the Closing, Seller and Parent shall
indemnify, defend and hold harmless Purchaser Indemnitees from and against any and all Damages (including Taxes) resulting from, arising out of or incurred in connection with: 

(a) any Pre-Closing Taxes; 

(b) any Tax liability imposed on an Entity as a result of such Entity having been a member of a consolidated, joint, unitary or combined group
for any U.S. or non-U.S. Tax purpose (other than such group the common parent of which was the Company); and 

(c) Seller’s share of any Transfer Taxes pursuant to Section 12.7. 

10.4. Indemnification Procedures. 

(a) If a Purchaser Indemnitee desires to assert any claim for indemnification provided for under this ARTICLE 10 in respect of, arising
out of or involving a claim or demand made by any Person (other than a Party or Affiliate thereof) against the Purchaser Indemnitee (a “Third Party Claim”), such Purchaser Indemnitee will notify Parent (the “Indemnifying
Party”), in writing of such Third Party Claim specifying in reasonable detail (to the extent known) the nature and basis for each such claim or demand, and the amount or the estimated amount of Damages sought thereunder to the extent then
ascertainable (which estimate will not be conclusive of the final amount of such Third Party Claim) (a “Third Party Claim Notice”) promptly after receipt by such Purchaser Indemnitee of written notice of the Third Party Claim;
provided, however, that the failure to timely give such notice will not reduce the Damages for which the Indemnifying Party is obligated to indemnify the Purchaser Indemnitee under this ARTICLE 10 except to the extent actually
prejudiced by such failure. The Purchaser Indemnitee will deliver to the Indemnifying Party, promptly after the Purchaser Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Purchaser
Indemnitee relating to the Third Party Claim; provided, however, that failure to provide any such copies will not affect the indemnification obligations provided hereunder except to the extent of any Damages resulting from the
prejudice of any claim or defense available to the Indemnifying Party as a result of such failure. 

  
 93 

 (b) If a Third Party Claim is made against a Purchaser Indemnitee, the Indemnifying Party
will be entitled to participate in the defense thereof and, within 30 days of receiving a Third Party Claim Notice with respect to such Third Party Claim, may assume the defense thereof and select counsel to act in such defense (which counsel will
be reasonably satisfactory to the Purchaser Indemnitee). Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the Indemnifying Party will not be liable to the Purchaser Indemnitee for legal expenses subsequently
incurred by the Purchaser Indemnitee in connection with the defense thereof, unless, in the reasonable opinion of counsel to the Purchaser Indemnitee, counsel for the Indemnifying Party could not adequately represent the interests of the Purchaser
Indemnitee because the interests of the Indemnifying Party are in conflict with those of the Purchaser Indemnitee. If the Indemnifying Party assumes such defense, the Purchaser Indemnitee will have the right to participate in the defense thereof and
to employ counsel, at its own expense (except as provided in the immediately preceding sentence), separate from the counsel employed by the Indemnifying Party. The Indemnifying Party will be liable for reasonable fees and expenses of outside counsel
employed by the Purchaser Indemnitee for any period during which the Indemnifying Party has not assumed the defense thereof and as otherwise contemplated by the two immediately preceding sentences. If the Indemnifying Party chooses to defend any
Third Party Claim, the Purchaser Indemnitee will cooperate in the defense or prosecution thereof. 
 (c) If the Indemnifying Party, within 30
days after written notice of any such Third Party Claim (or sooner if the nature of the Third Party Claim so requires) (i) does not assume control of the defense or (ii) after assuming control of the defense, fails or ceases to diligently
defend such Third Party Claim, which failure or cessation is not cured within 15 days after written notice thereof from the Purchaser Indemnitee, then the Purchaser Indemnitee will have the right to undertake the defense of such Third Party Claim,
and (iii) the reasonable and documented fees and expenses of outside counsel to the Purchaser Indemnitee in connection therewith will be considered “Damages” for purposes of this Agreement; provided, however, that in no
event will the fees and expenses of more than one outside counsel (in addition to one local counsel in each jurisdiction that is reasonably necessary) for the Purchaser Indemnitee with respect to a single Third Party Claim or a series of related
Third Party Claims be considered “Damages” for purposes of this Agreement. 
 (d) The Indemnifying Party may pay, settle or
compromise a Third Party Claim without the Purchaser Indemnitee’s prior written consent, so long as the Indemnifying Party assumes full responsibility for the payment of any amounts due with respect to such Third Party Claim, and any such
payment, settlement or compromise (i) includes an immediate and unconditional release of the Purchaser Indemnitee and its Affiliates, officers and directors from all Liability in respect of such Third Party Claim, (ii) does not subject the
Purchaser Indemnitee or any of its Affiliates, officers or directors to any injunctive relief or provide for any other non-monetary remedy, (iii) does not include a statement or admission of fault,
culpability or failure to act by or on behalf of any Purchaser Indemnitee, and (iv) simultaneously with the effectiveness of such settlement, payment or compromise, the Indemnifying Party pays in full any obligation imposed on the Purchaser
Indemnitee by such settlement, compromise or consent or such obligation is paid in full from the Escrow Account. 

  
 94 

 (e) The Parties will act in good faith in responding to, defending against, settling or
otherwise dealing with any Third Party Claims, and cooperate in any such defense and give each other reasonable access during normal business hours and upon reasonable advance notice to all information relevant thereto. Without limiting the
generality of this Section 10.4(e), the Party controlling the defense of any Third Party Claim will deliver, or cause to be delivered, to the other party copies of all correspondence, pleadings, motions, briefs, appeals or
other written statements relating to or submitted in connection with the defense of the Third Party Claim, and timely notices of, and the right to participate in any hearing or other court proceeding, meeting or negotiation relating to the Third
Party Claim. 
 (f) If a Purchaser Indemnitee desires to assert any claim for indemnification provided for under this ARTICLE 10 other
than a claim in respect of, arising out of or involving a Third Party Claim (a “Direct Claim”), such Purchaser Indemnitee will notify the Indemnifying Party in writing of such Direct Claim, specifying in reasonable detail (to the
extent known) the nature and basis for each such claim and the amount or the estimated amount of Damages sought thereunder to the extent then ascertainable (which estimate will not be conclusive of the final amount of such Direct Claim), and, to the
extent practicable, any other material details pertaining thereto (a “Direct Claim Notice”); provided, however, that the failure to timely give such notice will not reduce the Damages for which the Indemnifying Party
is obligated to indemnify the Purchaser Indemnitee under this ARTICLE 10 except to the extent of such Damages resulting from the Indemnifying Party being prejudiced by such failure. 

10.5. Limitations on Indemnification. 

(a) Parent will have no liability for any claim for indemnification pursuant to Section 10.2(a) (i) in respect
of any individual item, or group of related items, where the amount of Damages relating thereto is less than $50,000 in the aggregate (the “De Minimis”) (provided that Parent shall be liable for all claims of $50,000 or
greater from the first Dollar of damages incurred (subject to the Basket Amount)) and (ii) unless and until the aggregate amount of Damages for which it would be responsible for claims hereunder exceeds an amount equal to $7,000,000 (the
“Basket Amount”), in which case Parent will, subject to the other limitations hereunder, be liable for all Damages from the first Dollar of Damages incurred. Notwithstanding the foregoing, the limitations set forth in this
Section 10.5(a) will not apply to any claim for indemnification in respect of a breach or inaccuracy of the Seller Fundamental Representations. 

(b) The maximum aggregate amount of indemnifiable Damages payable by Parent in respect of claims pursuant to
Section 10.2(a) (other than in respect of a breach or inaccuracy of the Seller Fundamental Representations) or Section 10.3(a) (any such claim described in the foregoing, a “General
Claim”) will not exceed the Escrow Amount. 

  
 95 

 (c) Subject to the requirements of Section 10.6(b) (to the extent
applicable), no party hereto will be obligated to indemnify any other Person with respect to any Damages to the extent the amount of such Damages was included in the calculation of the adjustments reflected in the Final Purchase Price pursuant to
Section 2.4 (to the extent so included). 
 (d) The Parties agree and acknowledge that, for any amounts finally
determined to be payable by Parent in respect of General Claims, such amounts will be paid solely from funds then available in the Escrow Account and Parent will not be obligated to pay any such amounts remaining unpaid after the funds in the Escrow
Account have been exhausted; provided, however, that, if funds remaining in the Escrow Account are not sufficient to pay any General Claim as a result of funds having been released previously for claims pursuant to
Section 10.2 or Section 10.3 (in each case, other than General Claims), then Parent will be obligated to pay in full any such deficiency, up to the amount of funds from the Escrow Account that were
released to a Purchaser Indemnitee in respect of claims pursuant to Section 10.2 or Section 10.3 (in each case, other than General Claims). The Parties agree and acknowledge that, for any amounts
finally determined to be payable by Parent in respect of claims pursuant to Section 10.2 or Section 10.3 (in each case, other than General Claims), in each case, such amounts will be paid first
from funds then available in the Escrow Account only to the extent Purchaser elects, by written notice to Parent, to have such amounts paid from the Escrow Account and Parent will be obligated to pay any such amounts not paid from the Escrow
Account. 
 (e) Notwithstanding anything to the contrary in this Agreement, in no event will the Indemnifying Party have any liability to any
Purchaser Indemnitee for any exemplary or punitive damages, except to the extent payable to a third party in connection with a Third Party Claim. 

10.6. Indemnity Payments. 

(a) Subject to Section 10.5(e) and Section 10.6(b), (i) the Indemnifying Party will pay all
amounts payable pursuant to this ARTICLE 10, by wire transfer of immediately available cash funds in Dollars, promptly following receipt from a Purchaser Indemnitee of a bill for Damages that are the subject of indemnification hereunder,
unless the Indemnifying Party in good faith reasonably disputes the Damages, in which event it will promptly notify the Purchaser Indemnitee, and (ii) in any event, the Indemnifying Party will pay to the Purchaser Indemnitee, by wire transfer
in immediately available cash funds in Dollars, the amount of any Damages for which it is liable hereunder no later than three days following any determination of such Damages and the Indemnifying Party’s liability therefor. A
“determination” will exist when (A) the parties to the dispute have agreed on a resolution to the dispute, (B) a court of competent jurisdiction will have entered a final order or judgment, or (C) an arbitration or like
panel will have rendered a final determination with respect to disputes the parties have agreed to submit thereto. 

  
 96 

 (b) The amount of Damages recoverable by a Purchaser Indemnitee pursuant to this ARTICLE
10 with respect to an indemnity claim shall be reduced by (i) the amount of insurance proceeds or other amounts actually recovered by such Purchaser Indemnitee with respect to the Damages to which such indemnity claim relates, net of any
retention, deductible or collection costs and expenses in connection therewith or increases in premiums payable as a result thereof; (ii) the amount of any available judicial deposits directly relating to such indemnity claim to the extent
actually recovered by such Purchaser Indemnitee and (iii) the amount of any accrual or reserve to the extent specifically identified as relating to the subject of such indemnity claim and expressly included as a current liability in the
calculation of Closing Net Working Capital and taken into account in the calculation of the Final Purchase Price. A Purchaser Indemnitee will use its commercially reasonable best efforts to obtain the release of available judicial deposits directly
related to any Damages claims prior to seeking indemnification under this Agreement. If an insurance recovery is made by the Purchaser Indemnitee or any of its Affiliates (including recovery of any judicial deposits) with respect to any Damages for
which any such Person has been indemnified hereunder, then a refund equal to the aggregate amount of the recovery (net of any retention, deductible or collection costs and expenses in connection therewith or increases in premiums payable as a result
thereof) shall be made promptly to Parent. 
 10.7. Exclusivity of Indemnity. Except in the case of actual fraud (as to which none of
the limitations set forth in this ARTICLE 10 will apply), and subject to Section 13.2, from and after the Closing, the rights of any Purchaser Indemnitee under this ARTICLE 10 or ARTICLE 11 will be the
sole and exclusive remedy of such Purchaser Indemnitee for monetary damages with respect to claims for breach or inaccuracy of any of the representations, or warranties, or breach of any of the covenants and agreements, in each case, that are
indemnifiable under this ARTICLE 10 or ARTICLE 11; provided, however, that the provisions of this Section 10.7 shall not prevent or limit the rights of the Parties with respect to
Section 2.4. 
 10.8. Successors. The obligations of Parent under this ARTICLE 10 are intended to be,
and will be, binding upon (a) any successors or assigns of Parent or Seller, (b) any trustee, examiner, receiver, or other representative of Parent’s or Seller’s estate and (c) any other Person vested or revested with any
right, title or interest in or to a material portion of, or claiming any rights in or control over a material portion of, Parent’s or Seller’s assets as if such Person were Parent hereunder. Parent shall not take, nor shall it permit any
of its Affiliates or its or their respective Representatives, to directly or indirectly take any action that is intended or designed to circumvent or avoid Parent’s obligations under this ARTICLE 10 and ARTICLE 2. 

10.9. Effect of Indemnification Payments. Unless otherwise required by applicable law, all amounts paid pursuant to this ARTICLE
10, ARTICLE 11 and ARTICLE 12 shall be treated by such parties as an adjustment to the Purchase Price. In the event that such amounts are not considered as an adjustment to the Purchase Price, the amount of Damages shall be
increased to offset the estimated amount of any Taxes payable by the relevant Purchaser Indemnitee as a result of the receipt of the relevant indemnification payments. 

  
 97 

 ARTICLE 11. AI BRAZIL INDEMNIFICATION 

11.1. Survival. The representations and warranties contained in ARTICLE 5 of this Agreement (together with any right to assert
any claim with respect thereto) will survive the Closing and will remain in full force and effect until 5:00 p.m., New York City time, on the date that is the 18-month anniversary of the Closing Date, at which time they will terminate, except that
the AI Brazil Fundamental Representations will survive the Closing (together with any right to assert any claim with respect thereto) and remain in full force and effect indefinitely. The covenants and agreements contained in this Agreement that are
to be performed by AI Brazil in full on or prior to the Closing will not survive the Closing, except that such covenants and agreements that are related to the actions and deliveries of AI Brazil at Closing pursuant to
Section 3.2(b)(i) shall survive the Closing (together with any right to assert any claim with respect thereto) and will thereafter terminate at 5:00 p.m., New York City time, on the date that is the 18-month anniversary of the Closing Date. The covenants and agreements that are to be performed by AI Brazil in whole or in part after the Closing will survive the Closing (together with any right to assert any
claim with respect thereto) until performed in accordance with their terms. 
 11.2. Indemnification by AI Brazil. Subject to
the limitations set forth in this ARTICLE 11 and elsewhere in this Agreement, from and after the Closing, AI Brazil will indemnify, defend and hold harmless the Purchaser Indemnitees from and against any and all Damages that a Purchaser
Indemnitee actually suffers exclusively resulting from, arising out of or incurred in connection with (a) any failure of any representation or warranty made by AI Brazil in ARTICLE 5 to be true and correct as of the date of this
Agreement or as of the Closing Date as if given as of such date (except to the extent that such representation and warranty speaks only as of a particular date, in which case, as of such date); and (b) any nonfulfillment, violation or breach of
any covenant or agreement made by AI Brazil in this Agreement. For the avoidance of doubt, AI Brazil shall not have any other obligation to indemnify the Purchaser Indemnitees for any Damages under this Agreement, except as set forth in this
ARTICLE 11. 
 11.3. Indemnification Provisions. Sections 10.4, 10.5(a) (provided that, solely for
purposes of this Section 11.3, $2,100,000 shall replace $7,000,000 in the definition of Basket Amount), 10.5(e), 10.6, 10.7 and 10.8 shall apply to this ARTICLE 11, mutatis
mutandis. 
 11.4. Additional Limitations. The maximum aggregate amount of indemnifiable Damages payable by AI Brazil in respect
of claims pursuant to (i) Section 11.2(a) (other than in respect of a breach or inaccuracy of the AI Brazil Fundamental Representations) will not exceed $9,000,000 and (ii) this ARTICLE 11 shall not exceed
the Final AI Brazil Payment.

 ARTICLE 12. TAX MATTERS 

12.1. Tax Returns. 
 (a)
Pre-Closing Tax Returns. Seller shall prepare and file, or shall cause to be prepared and filed, all Tax Returns required by applicable law to be filed by any Entity for any Pre-Closing Tax Period (other than a Straddle Period) on a timely basis (taking into account any extensions received from the relevant Tax Authorities). Such Tax Returns shall be true, correct and complete in all
material respects. Seller shall prepare such Tax Returns on a basis consistent with those prepared for prior taxable periods unless a different treatment of any item is required by applicable Law, including an intervening change in Law. Purchaser
may elect to receive a copy of such Tax Return by submitting written notice of such election, in which case Seller shall deliver a copy of such Tax Return to Purchaser within five Business Days of receiving notice of Purchaser’s election.
Seller shall pay or cause to be paid all Taxes indicated as due and payable on such Tax Returns, except to the extent the amount of such Taxes has already been specifically reflected as a liability in the calculation of Closing Net Working Capital
and taken into account in determining the Final Purchase Price. 
 (b) Post-Closing Tax
Returns That Include Pre-Closing Taxes. Purchaser shall be responsible for preparing and filing all other Tax Returns with respect to the Company or any Entity that are required to be filed (including for
a Straddle Period) by the Company or such Entity. Such Tax Returns shall be true, correct and complete in all material respects. Purchaser shall prepare such Tax Returns on a basis consistent with those prepared for prior taxable periods unless a
different treatment of any item is required by applicable Law, including an intervening change in Law. To the extent any such Tax Return includes Pre-Closing Taxes for which Seller or Parent may be liable
under this Agreement (after taking into account any reasonably available exemption, deduction, credit or other item arising from Pre-Closing Taxes to reduce the amount of
Pre-Closing Taxes), Seller may elect to receive a copy of such Tax Return by submitting written notice of such election, in which case Purchaser shall deliver a copy of such Tax Return to Seller within five
Business Days of receiving notice of Seller’s election. 
 12.2. Apportionment. For purposes of this Agreement, in order to
apportion appropriately any Taxes relating to a Straddle Period, the Parties hereto shall, to the extent permitted or required under applicable Law, treat the Closing Date (as of the close of business) as the last day of the taxable year or period
of the Entities for all Tax purposes. In any case where applicable Law does not permit any Entity to treat the Closing Date as the last day of the taxable year or period, the portion of any Taxes that are allocable to the Pre-Closing Straddle Period shall be (x) in the case of Taxes that are imposed on a periodic basis, the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis
(such as real property taxes), the amount of such Taxes for the immediately preceding period) multiplied by a fraction the numerator of which is the number of calendar days in the Straddle Period ending on (and including) the Closing Date (as of the
close of business) and the denominator of which is the number of calendar days in the entire relevant Straddle Period; and (y) in 

  
 99 

 
the case of Taxes not described in (x), the amount that would be payable if the taxable year or period ended on the Closing Date (as of the close of business) based on an interim closing of the
books (and for such purpose, the taxable period of any entity in which an Entity holds a beneficial interest will be deemed to terminate at such time). For purposes of clause (y) of the preceding sentence, any exemption, deduction, credit or
other item that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis, determined by multiplying the entire amount of such item allocated to the Straddle
Period by a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. In the case of
any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this Section 12.2 shall be computed
by reference to the level of such items on the Closing Date. 
 12.3. Reimbursement. If either Purchaser or Seller (the
“Paying Party”) pays a Tax for which the other (the “Non-Paying Party”) is liable in accordance with Section 10.3, including any Pre-Closing Taxes paid in connection with a Tax Return described in Section 12.1(b) (but only to the extent the amount of such Taxes has not already been specifically reflected as a
liability in the calculation of Closing Net Working Capital and taken into account in determining the Final Purchase Price), the Paying Party shall be entitled to reimbursement from the Non-Paying Party in
accordance with this Section 12.3. Upon payment of any such Tax, the Paying Party shall present a statement to the Non-Paying Party setting forth the amount of reimbursement to which
the Paying Party is entitled, together with such supporting evidence as is reasonably necessary to calculate the amount to be reimbursed. The Non-Paying Party shall make such reimbursement promptly, in
immediately available funds, but in no event later than five Business Days after the presentation of such statement. 
 12.4. Tax
Contests. 
 (a) If a written notice of deficiency, proposed adjustment, adjustment, assessment, audit, examination or other
administrative or court proceeding, suit, dispute or other claim relating to Taxes (a “Tax Claim”) is delivered or sent to or commenced or initiated against any of the Entities by any Tax Authority with respect to Taxes or Tax
Returns of any of an Entity for which Purchaser or its Affiliates may reasonably be entitled to indemnification pursuant to Section 10.3, Purchaser or its Affiliates will promptly notify Seller in writing of the Tax Claim;
provided, however, that the failure to timely give such notice will not limit and reduce Purchaser’s right to indemnification hereunder except to the extent that the Indemnifying Party is prejudiced thereby. 

(b) With respect to Tax Claims of or relating solely to Taxes of an Entity for any Pre-Closing Period for which Parent and Seller may be liable
under Section 10.3, Parent may, upon written notice to Purchaser, assume and control the defense of such Tax Claim at its own cost and expense and with its own counsel, provided that Parent and Seller first
acknowledge their obligation to indemnify Purchaser for the asserted liability. Purchaser may retain separate co-counsel at its sole cost and 

  
 100 

 
expense and participate in the defense of the Tax Claim (including participation in any relevant meetings and conference calls). Parent or Seller (as applicable) will not enter into any
settlement with respect to any such Tax Claim without Purchaser’s prior written consent, which consent will not be unreasonably withheld, conditioned or delayed, and will keep Purchaser informed of all developments and events relating to all
Tax Claims the defense of which is controlled by Parent or Seller, as applicable (including promptly forwarding copies to Purchaser of any related correspondence). 

(c) With respect to Tax Claims of or relating to Taxes of any Entity for a Straddle Period, Purchaser will control the contest of any such Tax
Claim at its own cost and expense. To the extent any such contest relates to Taxes for which Parent and Seller might be liable under Section 10.3 or this ARTICLE 12, Parent may retain separate co-counsel at their
sole cost and expense and participate in the defense of the Tax Claim (including participation in any relevant meetings and conference calls). Purchaser will not enter into any settlement with respect to any such Tax Claim without Parent’s
prior written consent, which will not be unreasonably withheld, conditioned or delayed, and Purchaser will keep Parent informed of all developments and events relating to such Tax Claim (including promptly forwarding copies to Parent of any related
correspondence). 
 (d) With respect to Tax Claims of or relating solely to Taxes of an Entity for any Post-Closing Period, Purchaser will
control the defense of such Tax Claim at its own cost and expense and with its own counsel. 
 12.5. Cooperation. After the Closing,
each of Purchaser and Parent will (and will cause their respective Affiliates, which in the case of Parent includes Seller, to): (a) assist the other party in preparing and filing any Tax Returns which such other party is responsible for preparing
and filing in accordance with this ARTICLE 12; (b) reasonably cooperate with the other party in preparing for any audits of, or disputes with Governmental Authorities regarding, any Tax Returns which such other party is responsible for
preparing and filing in accordance with this ARTICLE 12; (c) make available to the other party and to any Governmental Authority as reasonably requested all information, records and documents relating to Taxes of the Entities;
(d) provide timely notice to the other Party (except for AI Brazil) in writing of any pending or threatened Tax audits or assessments of the Entities for taxable periods for which the other Party may have a Liability under
Section 10.3 or this ARTICLE 12; (e) furnish the other Party with copies of all correspondence received from any Governmental Authority in connection with any Tax audit or information request with respect to any
taxable period for which the other Party may have any liability under Section 10.3 or this ARTICLE 12; and timely sign and deliver such certificates or forms as may be necessary or appropriate to establish an
exemption from (or otherwise reduce), or file Tax Returns or other reports with respect to, Taxes resulting from the transactions contemplated by this Agreement, and timely provide the other party with powers of attorney or similar authorizations
necessary to carry out the purposes of this ARTICLE 12. 

  
 101 

 12.6. Tax Sharing Agreements. All tax sharing agreements, arrangements, policies and
guidelines, formal or informal, express or implied, to which any Entity may be a party or subject, and all rights and obligations thereunder shall terminate as of the Closing Date, and no Entity shall have any liability thereunder for any and all
amounts due in respect of periods prior to the Closing Date. 
 12.7. Transfer Taxes. Any Transfer Taxes imposed as a result of the
transactions contemplated by this Agreement will be borne 50% by Purchaser and 50% by Seller. The Party so required by applicable Law will file all necessary Tax Returns and other documentation with respect to all Transfer Taxes, except that any
such filings required to be made by AI Brazil shall be made by Parent or Seller, and, if required by the applicable Law, the other Party will, and will cause its Affiliates to join in the execution of any such Tax Returns and other documentation. If
a Party is required under Section 10.3 to indemnify the other Party in respect of any Transfer Taxes, the amount of the indemnification will be an amount equal to the amount by which the other Party has paid or is obligated
to pay exceeds 50% of the total amount of such Transfer Taxes. 
 12.8. Tax Matters Dispute. If, after negotiating in good faith, the
Parties (except for AI Brazil) are unable to reach an agreement relating to any Tax matter under this ARTICLE 12 within 30 days of receipt by a Party of written notice of such disagreement, the firm of the Independent Accountant shall select
an independent and impartial partner from such firm with significant experience related to tax disputes (the individual so selected, the “Independent Tax Professional”) to resolve the dispute. The determination of the Independent
Tax Professional shall be final and binding on Parent, Seller and Purchaser. 
 12.9. Purchaser Tax Acts. Purchaser shall not
(a) amend any Tax Return for a Pre-Closing Tax Period or (b) make any Tax election with retroactive effect to any Pre-Closing Tax Period, in each case to the
extent such amendment or election could reasonably be expected to increase the Liability of Seller or any of its Affiliates for Taxes (including any obligation to indemnify in respect of Taxes pursuant to this Agreement), without Seller’s or
Parent’s prior written consent, which consent will not be unreasonably withheld, conditioned or delayed. 
 ARTICLE 13. MISCELLANEOUS

 13.1. Expenses. Except as otherwise provided in this Agreement, whether or not the transactions contemplated hereby are
consummated, all costs and expenses (including any finder’s or investment banker’s fees and attorneys’ and accountants’ fees) incurred in connection with the negotiation and execution of this Agreement and each other agreement,
document and instrument contemplated hereby and the consummation of the transactions contemplated hereby and thereby will be paid by the Party incurring the expense. 

  
 102 

 13.2. Remedies. 

(a) Injunctive Relief. Damages at law may be an inadequate remedy for the breach of any of the covenants, promises and agreements
contained in this Agreement, and, accordingly, each Party will be entitled to injunctive relief with respect to any such breach, including specific performance of such covenants or an order enjoining a Party from any threatened, or from the
continuation of any actual, breach of the covenants contained in this Agreement. The rights set forth in this Section 13.2 will be in addition to any other rights that a Party may have at law or in equity. 

(b) Arbitration. When Parent determines, in good faith, that it will make its final liquidity distribution within six months, it shall
deliver to Purchaser an officer’s certificate so stating (the date of such certificate, which shall not be prior to the second anniversary of the Closing Date, the “Liquidation Certificate Date”). If the Liquidation Certificate
Date occurs on or before any time at which any claims for indemnification under ARTICLE 10 have been made but not yet resolved, then Parent and Purchaser shall, as promptly as reasonably practicable, submit all pending and unresolved
indemnification claims to be finally settled by binding arbitration administered by the International Chamber of Commerce (the “ICC”) in accordance with the Rules of Arbitration of the ICC then in effect (the “ICC
Rules”), except as modified herein. The arbitrators shall be instructed to determine the amount of damages that would reasonably be expected to arise from such unresolved claims, which amount, when determined by the arbitrators, shall be
immediately payable by Seller and Parent to Purchaser in satisfaction of such unresolved claims. The Parties agree that there shall be a tribunal of three arbitrators, one of whom shall be appointed by Parent and one of whom shall be appointed by
Purchaser, in each case, within 15 days of the date of notice of arbitration from either Party, and the third arbitrator, who shall chair the arbitral tribunal, shall be appointed by the party-appointed arbitrators within 15 days of the appointment
of the second arbitrator. Any arbitrator not timely appointed as provided herein shall, upon request of any party, be promptly appointed by the ICC in accordance with the ICC Rules. The decision of the arbitral tribunal shall be determined by a
majority of the tribunal. The tribunal’s award shall be made as promptly as practicable, and in any event within 90 days after the appointment of the arbitral tribunal, provided that failure to adhere to this time limit shall not be a
basis for challenging the award or a defense or objection to its confirmation or enforcement. The arbitral tribunal shall have the authority to grant monetary damages only, which may include the release of any amounts remaining in the Escrow
Account, and shall have no jurisdiction to vary the express terms of this Agreement. The award shall be in writing and shall state the reasons for the award. The arbitration shall be conducted in the English language and the seat and place of
arbitration shall be in New York County, New York. 
 13.3. Governing Law; Submission to Jurisdiction. This Agreement will be governed
by and construed in accordance with the Laws of the State of New York applicable to Contracts made and performed in such State. In connection with the resolution of any claim or dispute arising out of or in connection with this Agreement or the
transactions contemplated hereby, subject to Section 13.2(b), the Parties agree to unconditionally and irrevocably submit to the exclusive jurisdiction of (i) the United States District Court for the Southern District
of New York sitting in New York County or the Commercial Division, Civil Branch of the Supreme Court of the State of New York 

  
 103 

 
sitting in New York County and any appellate court thereof or (ii) the Chancery Court of the State of Delaware and any state appellate court thereof within the State of Delaware, or in the
event that such court declines to accept jurisdiction over a particular matter, in any state or federal court located within the State of Delaware. The Parties irrevocably waive, to the fullest extent permitted by applicable Law, any objection which
they may now or hereafter have to the laying of venue of any such dispute brought in any such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the Parties agrees that a judgment in any such dispute may be
enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. 
 13.4. Waiver of Jury Trial. TO THE
EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND,
ACTION OR CAUSE OF ACTION ARISING IN WHOLE OR IN PART UNDER, RELATED TO, BASED ON OR IN CONNECTION WITH THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN TORT OR CONTRACT OR OTHERWISE. ANY
PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 13.4 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY. 

13.5. Entire Agreement; Amendments and Waivers. (a) This Agreement (including the Schedules and Exhibits to this Agreement)
represents the entire understanding and agreement between the Parties with respect to the subject matter of this Agreement. 
 (b) This
Agreement may be amended, supplemented or changed, and any provision of this Agreement may be waived, only by written instrument making specific reference to this Agreement signed by (i) all Parties, in the case of any amendment, supplement or
modification or (ii) the Party against whom enforcement of any such waiver is sought, in the case of any waiver. 
 (c) No action taken
pursuant to this Agreement, including any investigation by or on behalf of a Party will be deemed to constitute a waiver by the Party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. The
waiver by any Party of a breach of any provision of this Agreement will not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise,
and no delay in exercising, any right, power or remedy hereunder will operate as a waiver thereof, nor will any single or partial exercise of such right, power or remedy by such Party preclude any other or further exercise thereof or the exercise of
any other right, power or remedy. 

  
 104 

 13.6. Notices. All notices and other communications under this Agreement will be in

 13.7.
Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any Law or public policy, all other terms or provisions of this Agreement will nevertheless remain in full force and effect
so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being
enforced, the Parties will negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as
originally contemplated to the greatest extent possible. 
 13.8. Binding Effect; Assignment. This Agreement will be binding upon and
inure to the benefit of the Parties and their respective successors and permitted assigns. Nothing in this Agreement will create or be deemed to create any third party beneficiary rights in any Person not a party to this Agreement. No assignment of
this Agreement or of any rights or obligations hereunder may be made by any Party, directly or indirectly (by operation of Law or otherwise), without the prior written consent of the other Parties and any attempted assignment without the required
consents will be void. No assignment will relieve the assigning Party of any obligation. Upon any permitted assignment, the references in this Agreement to the assigning Party will also apply to any such assignee unless the context otherwise
requires. 
 13.9. Non-Recourse. No past, present or future director, officer, employee,
incorporator, member, partner, stockholder, Affiliate, agent, attorney or representative of a Party, nor any present or future director of Nextel Holdings, will have any liability for any obligations or liabilities of such Party or of Nextel
Holdings (as applicable) under this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby. On the Closing Date, Purchaser shall (or shall cause its applicable Affiliate to) adopt the
shareholder resolutions contemplated by Section 3.2(a)(iv), acknowledging the 

  
 106 

 
resignation of the current managers of Nextel Holdings or the Company (as applicable) with effect upon the Closing and granting such managers provisional discharge in respect of the performance
of their duties as managers of Nextel Holdings or the Company (as applicable). After the Closing, to the extent applicable after the Closing, Purchaser shall (or shall cause its applicable Affiliate to) confirm such discharge at the next two annual
general meetings of the shareholders of Nextel Holdings and the Company, in connection with approval of the financial statements for the years 2018 and 2019 at the time of approval of Nextel Holdings’ and the Company’s financial statements
for the years 2018 and 2019, such discharge to then be a full and unconditional manager discharge for performance of their duties as managers. 

13.10. Legal Representation. Purchaser acknowledges and agrees that Jones Day has acted as counsel for NIIH and Parent, and that, in the
event of any post-Closing disputes between the Parties, NIIH and Parent reasonably anticipate that Jones Day will represent them in such matters. Accordingly, Purchaser expressly consents to Jones Day’s representation of one or more of NIIH and
Purchaser in any post-Closing matter in which the interests of Purchaser on the one hand and any of NIIH and Parent, on the other hand, are adverse, whether or not such matter is one in which Jones Day may have previously advised any of NIIH, Parent
or their respective Affiliates, and consents to the disclosure by Jones Day to any of NIIH, Parent or their respective Affiliates of any information learned by Jones Day in the course of its representation of NIIH and Parent, whether or not such
information is subject to attorney-client privilege or Jones Day’s duty of confidentiality. 
 13.11. Parent Guarantee. In
connection with the transactions contemplated by this Agreement, Parent hereby irrevocably, absolutely and unconditionally guarantees the due, punctual and complete performance and payment (and not merely collection) in full of all obligations and
liabilities of the Entities, NIIH and its Affiliates under this Agreement and the Company Share Transfer Agreement, and all obligations and liabilities of the Company under the Nextel Holdings Share Transfer Agreement, as and when due and payable or
required to be performed pursuant to any provisions of this Agreement, the Nextel Holdings Share Transfer Agreement and the Company Share Transfer Agreement, subject to the terms and conditions hereof and thereof (the “Guaranteed
Obligations”) and agrees that Purchaser and AI Brazil shall be entitled to enforce directly against Parent any of the Guaranteed Obligations. To the fullest extent permitted by applicable Law, Parent waives presentment to, demand of payment
from and protest to any other Person of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. The obligations of Parent hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the
invalidity, illegality or unenforceability of the Guaranteed Obligations, or otherwise. In the event that Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing
or surviving corporation or entity of such 

  
 107 

 
consolidation or merger or (ii) other than as contemplated by this Agreement, transfers or conveys all or substantially all of its properties and other assets to any Person, then, and
in each such case, Parent shall cause proper provision to be made so that such successor or assign shall expressly assume the obligations set forth in this Section 13.11. 

13.12. Release. Effective as of the Closing, Seller and AI Brazil, for itself and on behalf of each of its Affiliates and each of its
and their respective past and present predecessors, successors and assigns (collectively, the “Seller Releasing Persons”), hereby absolutely, unconditionally and irrevocably releases, discharges and covenants not to sue, to the
fullest extent permitted under applicable Law, Purchaser and each of its Subsidiaries (including, for the avoidance of doubt, the Entities) and each of its and their respective past and present directors, officers, employees, members, managers,
partners, shareholders, Affiliates, agents and representatives (collectively, the “Purchaser Released Persons”) from any and all rights, claims, demands, actions, causes of action, judgments, obligations, contracts, agreements,
debts and liabilities whatsoever, whether known or unknown, suspected or unsuspected, both at law and in equity (including any right, whether arising at law or in equity, to seek indemnification, contribution, cost recovery, damages or any other
recourse or remedy, including as may arise under common law) that any Seller Releasing Person or any Person claiming through or under a Seller Releasing Person now has, has ever had or may hereafter have against the Purchaser Released Persons or any
of them from any transaction, event, occurrence, action or inaction with respect to periods at or prior to the Closing arising out of or relating in any way to (a) any Seller Releasing Person’s relationship as a direct or indirect
shareholder, member or manager of any of the Entities at or prior to the Closing, (b) the organization, management or operation of the Entities at or prior to the Closing, (c) any claim that the amounts payable to Seller or AI Brazil as
set forth on the Payout Schedule are incomplete or inaccurate or that Seller or AI Brazil was entitled to receive payment of any different amount (subject to actual payment of the amounts set forth in the Payout Schedule to Seller or AI Brazil, as
the case may be) and (d) that certain letter agreement entered into by and among Parent, NIIH and AI Brazil, and acknowledged by the Company, dated as of the date of this Agreement; provided, however, that this
Section 13.12 shall not be deemed to include the release of any Claims against a Purchaser Released Person arising under this Agreement or any Ancillary Agreement (for the avoidance of doubt, other than the letter agreement
referenced in clause (d) above) in accordance with the terms hereof or thereof. 
 13.13. Counterparts. This Agreement may be
executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement.

Re: Nextel Holdings S.à r.l. 
 Dear Edward, 

We refer to the Shareholders Agreement (the “Shareholders Agreement”) in relation to Nextel Holdings S.à r.l. (the
“Nextel Holdings”), dated June 5, 2017, among the Company, Ice Group Brazil Holdings BV (formerly known as AINMT Brazil Holdings B.V.), NII International Telecom (“NII Telecom”), NII Brazil Holdings S.à
r.l. (the “Company”) and NII Holdings, Inc. (“NII Parent”). 
 Also, we refer to the Purchase Agreement (the
“Purchase Agreement”), dated March 18, 2019, among América Móvil, S.A.B. de C.V. (“Purchaser”), NII International Holdings S.à r.l. (“NIIH”), AI Brazil Holdings B.V.
(formerly known as Ice Group Brazil Holdings BV, hereinafter “AI Brazil” and, collectively with its Affiliates, “Access,” “you” and “your”) and NII Parent. NII Parent, NIIH
and AI Brazil are sometimes referred to herein, collectively, as the “Parties,” and each as a “Party”. Capitalized terms used but not defined in this letter have the meaning given to them in the Shareholders
Agreement or Purchase Agreement, as applicable. 
 The Parties wish to document certain understandings in respect of the transfer by (i) NIIH of all of
the issued and outstanding equity interests of the Company and (ii) AI Brazil of the AI Brazil Shares indirectly to Purchaser pursuant to the Purchase Agreement and the application of the Shareholders Agreement to such transfer. 

 In consideration of the mutual agreements, provisions and covenants contained in this letter (this
“Letter Agreement”) and the Purchase Agreement, the Parties hereby agree as follows: 
  

	1.	 NII Parent represents and warrants to Access that it has provided to Access all material information related to
NII Parent’s sale of its interest in Nextel Holdings pursuant to the Purchase Agreement and the estimated return to NII Parent’s stockholders relating to such sale and the anticipated winding up and dissolution of NII Parent. NII Parent
will provide to Access true and correct copies of all material written information provided to any stockholders of NII Parent in connection with soliciting or obtaining the Parent Stockholder Approval. Further, NII Parent confirms that, except for
the Purchase Agreement, there are no agreements between NII Parent, NIIH and any of the Entities, on the one hand, and the Purchaser or its Affiliates relating to the transactions contemplated under the Purchase Agreement, on the other hand, and
that neither NII Parent, nor any of its Affiliates, will enter into any such agreements between signing and closing under the Purchase Agreement without the consent of Access (such consent not to be unreasonably withheld or delayed).

  

	2.	 NII Parent shall promptly (and in any event, within 48 hours) advise Access orally and in writing (which may be
by email) of the receipt by NII Parent or any of its Affiliates or Representatives of any Acquisition Proposal, any request to engage in discussions or negotiations with respect to an Acquisition Proposal or any request for information that would
reasonably be expected to relate to an Acquisition Proposal, and in connection with such notice, provide to Access the material terms and conditions of any such Acquisition Proposal (including the identity of the third party making any such
Acquisition Proposal) and of any changes thereto. NII Parent shall promptly advise Access orally and in writing (which may be by email) of the commencement of any discussions with any third party or its Representatives regarding any Acquisition
Proposal by such third party. NII Parent shall keep Access informed (orally and in writing) in all material respects on a timely basis of the status and details (including, within 48 hours after the occurrence of any amendment, modification,
material development or negotiation) of any such Acquisition Proposal or request, including promptly furnishing to Access copies of any written Acquisition Proposal, any other written materials that describe any such Acquisition Proposal, any
material correspondence relating thereto, and draft documentation with respect to such Acquisition Proposal. 

  

	3.	 In the event that the Parent Board has determined that an Acquisition Proposal constitutes a Superior Proposal,
NII Parent shall, not less than seven (7) Business Days prior to accepting such Superior Proposal, notify Access orally and in writing (which may be by email) that it believes that such Acquisition Proposal constitutes a Superior Proposal and
such written notice (which may be by email) shall specify the material terms and conditions of such Superior Proposal (including the identity of the Person making the proposal) and contemporaneously furnish to Access a copy of the relevant
acquisition agreement or other relevant transaction documents. In the event that NII Parent determines to accept the aforementioned Acquisition Proposal, NII Parent further undertakes to (a) prior to terminating the Purchase Agreement,
reasonably cooperate and consult with Access with respect to such Superior Proposal, including by providing Access a reasonable opportunity to participate in discussions with respect to the acquisition of the AI Brazil Shares with the Person making
the Superior Proposal so that Access may ensure that such Person will acquire the AI Brazil Shares (directly or indirectly) on terms acceptable to Access, and (b) assume all liability for any action brought by Purchaser arising from or relating
to (i) the termination of 

  
 2 

	 	
the Purchase Agreement by NII Parent or by Purchaser as a result of a breach by NII Parent or the Company, or (ii) NII Parent’s failure to pay the Company
Break-Up Fee in accordance with Section 3.4 of the Purchase Agreement. For the avoidance of doubt, in the event that Parent terminates the Purchase Agreement to enter into a definitive agreement
for a Superior Proposal, (A) NII Parent will pay the Company Break-Up Fee in accordance with the terms of Section 3.4 of the Purchase Agreement, (B) to the extent NII Parent is not reimbursed
(directly or indirectly) for the amount of the Company Break-Up Fee, then (i) the first $25,000,000 of the purchase price under such Superior Proposal shall be paid to NII Parent as reimbursement for NII
Parent’s payment of the Company Break-Up Fee, and (ii) Access shall not have any right to any reimbursement or payment (directly or indirectly) of any portion of the Company Break-Up Fee by a Person making such Superior Proposal. 

  

	4.	 If NIIH or NII Parent terminates the Purchase Agreement in order to accept a Superior Proposal, prior to
accepting such Superior Proposal, NII Parent, NII Telecom and the Company and each of their respective Affiliates will comply with the terms of the Shareholders Agreement, including with the provisions of Section 2.5 or 2.6 thereof; provided,
however, that upon receipt of a Sale Notice, Access will have seven (7) Business Days to exercise its option to purchase the Offered Shares. 

  

	5.	 Notwithstanding Paragraph 4 and the rights of Access under the Shareholders Agreement, in the event that NII
Parent or any of its Subsidiaries or Affiliates enters into a definitive agreement with respect to a Superior Proposal, (a) NII Parent hereby undertakes that, if NIIH or its Affiliates exercise the drag along rights pursuant to Section 2.8
of the Shareholders Agreement in connection with any such Superior Proposal, (i) Access will only be obligated to indemnify the purchaser under such Superior Proposal for matters relating to fundamental representations applicable to
Access’s interests in Nextel Holdings in substantially the same form as set out in Article 5 of the Purchase Agreement or any breach by Access of its covenants under the definitive agreement for a Superior Proposal, (ii) Access will not be
obligated to participate in or otherwise contribute to any indemnification escrow, holdback, reserve or other contingent obligation that may be part of any Superior Proposal, (iii) the covenants and obligations applicable to Access in any such
Superior Proposal will be on substantially the same terms contemplated under the Purchase Agreement and (iv) the consideration to be received by Access for the sale of the AI Brazil Shares shall meet the minimum threshold set forth in
Section 2.8 of the Shareholders Agreement, and (v) Access shall not be required to contribute (directly or indirectly) to any costs and/or expenses of NII Parent or its Affiliates in respect of either the transaction pursuant to the
Purchase Agreement and/or a Superior Proposal, and (b) Access shall have the right to elect to exercise the tag along rights pursuant to Section 2.7 of the Shareholders Agreement in connection with any such Superior Proposal, irrespective
of the form of such transaction, and if Access elects to exercise such rights, (i) Access will only be obligated to indemnify the purchaser under such Superior Proposal for matters relating to fundamental representations applicable to
Access’s interests in Nextel Holdings in substantially the same form as set out in Article 5 of the Purchase Agreement or any breach by Access of its covenants under the definitive agreement for a Superior Proposal, (ii) Access will not be
obligated to participate in or otherwise contribute to any indemnification escrow, holdback, reserve or other contingent obligation that may be part of any Superior Proposal, (iii) the covenants and obligations applicable to Access in any such
Superior Proposal will be on substantially the same terms contemplated under the Purchase Agreement and (iv) Access shall not be required to contribute (directly or indirectly) to any costs and/or expenses of NII Parent or its Affiliates in
respect of either the transaction pursuant to the Purchase 

  
 3 

	 	
Agreement and/or a Superior Proposal. Notwithstanding anything in the Shareholders Agreement to the contrary, for purposes of giving effect to this Paragraph 5, each reference to “Retained
NII Group” in Section 2.7 of the Shareholders Agreement (and the definitions used therein), shall be deemed to include NII Parent and each of its direct and indirect Subsidiaries. 

 

	6.	 NII Parent will not refer to Access or its Affiliates in the Proxy Statement required under the Purchase
Agreement without the prior written consent of Access, which consent will not be unreasonably withheld or delayed, unless such disclosure with respect to Access or its Affiliates is otherwise required by applicable Law, in which case, NII Parent
will provide Access a reasonable opportunity to review and comment on such disclosure. 

  

	7.	 NII Parent shall indemnify, defend and hold harmless Access and its Affiliates and, in each case, their
respective officers, directors and employees (the “Access Indemnitees”) from, against and in respect of any and all Damages that the Access Indemnitees actually suffer resulting from an action or proceeding brought or threatened in
writing by a stockholder or bondholder of NII Parent or any third party (other than Purchaser (any indemnification for which shall be covered pursuant to paragraph 3 above) or any Affiliate of Access) making a claim specifically in relation to the
transactions contemplated under the Purchase Agreement, this Letter Agreement or any Superior Proposal. The Parties acknowledge and agree that NII Parent’s indemnification obligation hereunder shall terminate and be of no further force or
effect if no claim or threat is brought by an NII Parent stockholder or bondholder or a third party prior to the date that is 120 days immediately following the closing date of the Purchase Agreement or Superior Proposal, as applicable.

  

	8.	 NII Parent shall indemnify, defend and hold harmless AI Brazil from and against any and all Damages that AI
Brazil actually suffers resulting from, arising out of or incurred in connection with: 

  

	 	(a)	 any and all Unpaid Transaction Expenses; 

 

	 	(b)	 a reduction in the portion of the Purchase Price payable to AI Brazil pursuant to Article 2 of the Purchase
Agreement as a result of, or claims by Purchaser under the Purchase Agreement arising out of or related to: (i) any Accrued Tax Contingencies or any contingent Tax liabilities reflected in Section 6.6 of the Company Disclosure Schedule or
Attachment D to Section 6.13 of the Company Disclosure Schedule; (ii) any Taxes imposed on NII Parent or any of its Affiliates other than the Entities; (iii) the portion of Pre-Closing Taxes in
excess of the AI Brazil Percentage of such Pre-Closing Taxes that are directly related to the operations of the Entities in the Ordinary Course and are properly included as current liabilities in the
calculation of Net Working Capital in accordance with the Accounting Principles; or (iv) any Taxes included in the calculation of Net Working Capital that were incurred outside of the Ordinary Course or that were improperly included in the
calculation of Net Working Capital pursuant to the Accounting Principles; 

  

	 	(c)	 any Liabilities or reduction in Purchase Price associated with any Intercompany Notes Modification or Requested
Notes Modification; and 

  

	 	(d)	 any amounts payable under the Retention Plan, whether or not the transactions contemplated by the Purchase
Agreement are consummated. 

  
 4 

	9.	 NII Parent represents and warrants to Access that no Transaction Expenses have been paid by Nextel Holdings or
any of the Entities. From the date of the Purchase Agreement until the Closing or the earlier termination of the Purchase Agreement, NII Parent will not, and NII Parent will cause the Entities not to, amend, change, waive or otherwise modify the
Intercompany Notes or agree to a Requested Notes Modification without the prior written consent of Access (which may be withheld, conditioned or delayed in Access’s sole discretion, for any reason or for no reason, and without liability).

  

	10.	 At least five (5) Business Days prior to NII Parent delivering the Estimated Closing Statement or Payout
Schedule to Purchaser pursuant to Section 2.2(c) of the Purchase Agreement, NII Parent will prepare and deliver to Access for its review and approval, a draft of the Estimated Closing Statement and Payout Schedule showing the elements thereof
specified in the Purchase Agreement, including the Estimated AI Brazil Amount. NII Parent and Access will work together in good faith to agree the contents of the Estimated Closing Statement and Payout Schedule and NII Parent shall not submit the
Estimated Closing Statement or Payout Schedule to Purchaser or agree any changes to the form or content thereof, without the prior written consent of Access (such consent not to be unreasonably withheld, conditioned or delayed). The Parties agree
that the terms herein shall apply mutatis mutandis in respect of any Superior Proposal. 

 At least five (5) Business
Days prior to delivering the 2020 Transaction Budget to Purchaser, NII Parent will prepare and deliver to Access for its review and approval, a draft of the 2020 Transaction Budget, including the amount of proposed capital expenditures to be
included therein. NII Parent and Access will work together in good faith to agree the contents of the 2020 Transaction Budget and NII Parent shall not submit the 2020 Transaction Budget to Purchaser or agree any changes to the form or content
thereof, without the prior written consent of Access (such consent not to be unreasonably withheld, conditioned or delayed). 
  

	11.	 NII Parent will provide information to, and reasonably consult and cooperate with, Access in respect of any of
the undertakings or actions of NII Parent in relation to the calculation and determination of the Final Purchase Price pursuant to Section 2.4 of the Purchase Agreement, including by facilitating such access, during regular business hours, to
the books and records of the Seller and the Entities and the employees and other service providers (including accountants and other advisors) to the Entities as Access may reasonably request; provided that neither Parent nor Seller will be required
to permit any inspection, or to disclose any information, that in the reasonable judgment of Parent or Seller, as applicable, would (a) waive the protection of an attorney-client privilege or (b) would violate any confidentiality
obligations to which Parent or Seller is bound; provided, further, that Parent or Seller, as applicable, shall use commercially reasonable efforts to permit such inspection or provide such information in a manner that would not result in the waiver
of such privilege or violate such confidentiality obligations, including, in the case of clause (b), by obtaining the consent of such third party if so requested by Access. Without limiting the generality of the foregoing, NII Parent shall promptly
(and in any event, within 48 hours) advise Access orally and in writing (which may be by email) of the receipt by NII Parent or any of its Affiliates or representatives of the Closing Statement or any communication from Purchaser in respect of the
calculation of the Final Purchase Price, which notice shall include a copy of the Closing Statement or such other communication (if in writing). NII Parent and Access will work together in good faith to agree the contents of any Closing Statement
Dispute Notice and NII Parent shall not agree to the Closing Statement the Final Purchase Price, or any element thereof, or submit any Closing Statement Dispute Notice to Purchaser, without the prior written

  
 5 

	 	
consent of Access (such consent not to be unreasonably withheld or conditioned). If NII Parent delivers a Closing Statement Dispute Notice, then NII Parent and Access will work together in good
faith to resolve the Disputed Items with Purchaser during the Resolution Period. NII Parent shall keep Access fully informed of all proposals, negotiations and communications in respect of the attempt to resolve any Disputed Items or the submission
of any Unresolved Items to the Independent Accountant (including by providing Access with copies of all related support and backup materials) and shall not agree to any compromise, settlement or resolution of any such Disputed Item or any payment in
respect thereof, without the prior written consent of Access (such consent not to be unreasonably withheld, conditioned or delayed). 

  

	12.	 NII Parent will use its reasonable best efforts to notify Access prior to exercising any of its termination
rights under Section 3.4 of the Purchase Agreement and shall, to the extent practicable, consult with Access prior to exercising such rights. In addition, NII Parent shall provide to Access, as promptly as practicable, copies of any notices
delivered by NII Parent (or received by NII Parent) pursuant to Sections 3.4, 3.5 or 3.6 of the Purchase Agreement. 

  

	13.	 To the extent NII Parent is provided the opportunity to review and comment on any submission or communication
required in connection with the process of obtaining the Regulatory Approval or Antitrust Approval, NII shall provide Access as much time as reasonably practicable to review and comment on, and will take into account and reflect any reasonable
comments from Access with respect to, any such submissions or communications. 

  

	14.	 NII Parent undertakes to Access that it will procure that the Company and its Subsidiaries will conduct
business in the ordinary course (in accordance with the business plan, past practice and Section 8.2 of the Purchase Agreement) (the “Ordinary Course”) during the period between signing and closing of the Purchase Agreement.
Further NII Parent undertakes not to operate the business of the Entities, or permit the business of any of the Entities to be operated, in a manner that is outside of the Ordinary Course or that would intentionally result in a negative impact on
the purchase price adjustment under the Purchase Agreement. 

  

	15.	 The Parties acknowledge that between signing and closing of the Purchase Agreement or any Superior Proposal,
Nextel Holdings shall require equity funding. The Parties hereby agree to procure that Nextel Holdings shall undertake such equity capital raising at a valuation equal to that established by the price mechanism under the Purchase Agreement or any
Superior Proposal. In addition, any equity capital raising will be undertaken pursuant to the terms and conditions set out in the Shareholders Agreement. 

  

	16.	 Subject to the terms and conditions set forth in this Paragraph 16, without prejudice to the rights and
obligations of the relevant parties under the Investment Agreement (as defined in the Shareholders Agreement) and the undertaking agreement entered into on October 15, 2018, by among NII Parent and AI Brazil (the “Undertaking
Letter”) in respect of the proceeds of an escrow established pursuant to the Escrow Agreement, dated January 26, 2015, among NIU Holdings LLC (“NIU”), Citibank, N.A. and AT&T Mobility Holdings B.V. (as permitted
assignee) (the “Mexico Escrow”), the Parties hereby agree in connection with the transactions contemplated under the Purchase Agreement and subject to Rule 408 of the Federal Rules of Evidence that: 

 

	 	(a)	 Until Closing of the Purchase Agreement or Superior Proposal, 

  
 6 

	 	(i)	 to the extent payment is made from the Mexico Escrow to NIU (the “Released Amount”), NII
Parent will procure that NIU transfers the Released Amount into a separate bank account (the “Escrow Bank Account”) designated to hold only the Released Amount and shall not use such monies for any reason other than those set out
herein or pursuant to the Undertaking Letter; and 

  

	 	(ii)	 the Parties otherwise agree that the terms of the Undertaking Letter are hereby suspended until Closing (of the
Purchase Agreement or Superior Proposal) and upon Closing of the Purchase Agreement (or Superior Proposal) shall terminate. 

  

	 	(b)	 Upon Closing of the Purchase Agreement or a Superior Proposal, as applicable, and thereafter, within five
(5) Business Days of receipt of a Released Amount, NII Parent will cause NIU to pay to Access the first $10,000,000 of the Released Amount (the “Initial Release”) from the applicable escrow account at Citibank N.A. and an
amount equal to 6% of all additional proceeds released from the Mexico Escrow after the Initial Release (the “Escrow Arrangement”). 

  

	 	(c)	 If the Purchase Agreement is terminated, the foregoing Escrow Arrangement shall no longer apply, and the terms
and conditions of the Undertaking Letter shall be reinstated and be in full force and effect. 

  

	17.	 The Parties hereby further agree that, whether or not expressly referenced herein, the terms of this Letter
Agreement shall apply mutatis mutandis in respect of any Acquisition Proposal or Superior Proposal (including any proposal which in substance is an Acquisition Proposal or Superior Proposal but is made following acceptance and in respect of a
Superior Proposal) except in the case of the AI Brazil consent right in paragraph 9, which shall not be unreasonably withheld, delayed or conditioned in respect of any other Acquisition Proposal or Superior Proposal. 

Clauses 13.2, 13.3, 13.4, 13.5, 13.6, 13.7, 13.8 and 13.13 of the Purchase Agreement shall apply to and are hereby incorporated into the terms of this Letter
Agreement, mutatis mutandis. The Parties hereby acknowledge and agree that the execution of the Purchase Agreement by the parties thereto will in no way be deemed or constitute a breach by any Party of the Shareholders Agreement, provided,
that the Parties agree to exercise their respective rights in accordance with the Shareholders Agreement. 
 If the above reflects our understanding and
agreement with respect to the foregoing matters correctly, please so confirm by signing the enclosed copy of this Letter Agreement.
