WHEREAS, the Executive has been employed by the Company as its Chief Executive Officer; and

WHEREAS, the Parties wish to confirm the termination of the Executive's employment with the Company and set forth their agreement as to certain payments, benefits, rights and obligations of the Parties in connection therewith.

NOW, THEREFORE, in consideration of the covenants and conditions set forth herein and other good and valuable consideration, the receipt and sufficiency of which the Parties hereby acknowledge, the Parties, intending to be legally bound, hereby agree as follows:

1.Resignation from Positions. The Parties hereby mutually agree that the Executive will resign from the Company, and consequently his employment with the Company will terminate, effective as of the close of business on December 13, 2012 (the “Separation Date”). Accordingly, the Executive hereby resigns, effective as of the Separation Date, from all positions, titles, duties, authorities and responsibilities with, arising out of or relating to his employment with the Company and subsidiaries and its affiliates (the “Company Group”), including without limitation as the Chief Executive Officer of the Company and as a member of the Board of Directors of the Company (the “Board”), and agrees to execute all additional documents and take such further steps as may be required to effectuate such resignations. For purposes of clarity, this Section 1 shall survive any revocation this Agreement by the Executive pursuant to Section 7 hereof.

2.Severance Benefits; Treatment of Company Equity; Reimbursement of Expenses. In connection with the Executive's termination of employment, the Company shall pay and provide to the Executive, and notwithstanding any and all other amounts that may be due Executive on the date hereof or in the future, whether accrued or unaccrued, by the Company Group, including pursuant to the NII Holdings, Inc. Severance Plan (as amended and restated as of July 22, 2008), the Executive shall only be entitled to, the following severance payments and benefits set forth in this Section 2 of this Agreement, at the time or times set forth herein:

(a)Severance Payment. If Executive has executed this Agreement as of December 23, 2012 and not revoked this Agreement as of December 31, 2012, the Company shall pay Executive the following:

(i)Pursuant to Section 5.04 of the NII Holdings, Inc. Severance Plan:

(1) twelve (12) months of annual earnings in an amount equal to $946,000, $517,000 of which will be paid in a lump sum on December 31, 2012 pursuant to the exemptions described in Treasury Regulation §§ 1.409A-1(b)(9)(iii) and 1.409A-1(b)(9)(v)(D), and $429,000 of which will be paid in a lump sum on the date that is six months after the Separation Date (or if such date is not a business day, then the next business day thereafter) subject to ordinary income tax withholding; and

(2) A pro-rated annual incentive bonus for the calendar year 2012, based on the number of days the Executive was actually employed by the Company during calendar year 2012, which would be payable to Executive under the Company's 2012 annual bonus plan, calculated based on the Company's actual performance for 2012, using the same performance multiples and payout percentages applicable to other senior executives at the Company's headquarters, with no discretion to reduce the bonus or any performance metrics or criteria. For purposes of this calculation and the Company's 2012 annual bonus plan, Executive shall receive a rating of “consistently meets expectations” for the twenty percent (20%) personal performance component of the annual bonus, to be paid in a lump sum on the date that is six months after the Separation Date (or if such date is not a business day, then the next business day thereafter) subject to ordinary income tax withholding; and

(ii)    An additional amount equal to $1,346,000 in connection with the restrictive covenants hereunder, to be paid in a lump sum on December 31, 2012, subject to ordinary income tax withholding.

(e)Employee Benefits. The Executive shall be entitled to benefits under the Company's employee pension benefit plans and employee welfare benefit plans (each as defined in the Employee Retirement Income Security Act of 1974, as amended), according to the terms of such plans.

(f)Indemnification and Insurance. The Company shall continue to indemnify and hold the Executive harmless against expenses, including reasonable attorney's fees judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with any proceeding arising by reason of actions taken by the Executive within the scope of his duties as an officer, employee and director of the Company or the Company Group, in accordance with its policies, by laws, and articles of incorporation as in effect as of the Separation Date. This Agreement shall not affect any indemnification or other rights and benefits afforded to the Executive by the Company's certificate of incorporation or by laws.

For two (2) years following the Separation Date (the “Restricted Period”), the Executive will not, within any jurisdiction, other than the fifty states comprising the United States of America on the date hereof, in which the Company Group is doing or is qualified to do business, directly or indirectly, own, manage, operate, control, be employed by or participate in the ownership, management, operation or control of, or be connected in any manner with, any business which is in competition with (i) the business of the Company Group conducted as of the Separation Date or (ii) any business the Company Group has specific plans to conduct in the future and as to which the Executive was aware of such planning at or prior to the Separation Date; provided, that the Executive's ownership of securities of two percent (2%) or less of any class of securities of a public company will not, by itself, be considered to be competition with the Company Group.

(b)Nonsolicitation. During the Restricted Period, the Executive will not (i) hire or employ, solicit for employment or otherwise contract for the services of any individual who is or at any time was an employee or consultant of the Company Group; (ii) otherwise induce or attempt to induce any employee or consultant of the Company Group to leave the employ or service of the Company Group, or in any way interfere with the relationship between the Company Group and any employee or consultant respectively thereof; or (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of the Company Group to cease doing business with the Company Group, or interfere in any way with the relationship between any such customer, supplier, licensee or business relation and the Company Group.

(c)Nondisclosure.

(i)The Executive will not divulge, transmit or otherwise disclose (except as legally compelled by court order, and then only to the extent required, after prompt notice to the Company's General Counsel of any such order), directly or indirectly, other than in the regular and proper course of business of the Company Group, any customer lists, trade secrets or other confidential knowledge or information with respect to the operations or finances of the Company Group or with respect to confidential or secret processes, services, techniques, customers or plans with respect to the Company Group, including, without limitation, any know-how, research and development, software, code, databases, inventions, processes, formulae, technology, designs and other intellectual property, information concerning finances, investments, profits, pricing, costs, products, services, vendors, customers, clients, partners, investors, personnel, compensation, recruiting, training, advertising, sales, marketing, promotions, government and regulatory activities and approvals concerning the past, current or future business, activities and operations of the Company Group (all of the foregoing collectively hereinafter referred to as “Confidential Information”). Confidential Information shall not include any information that is or becomes publicly available or generally known through no action of the Executive.

(ii) The Executive will not use, directly or indirectly, any Confidential Information for the benefit of anyone other than the Company Group; provided, that the Executive has no obligation, express or implied, to refrain from using or disclosing to others any such knowledge or information which is or hereafter will become available to the general public other than through disclosure by the Executive.

4.Remedies. The Parties acknowledge and agree that the Executive's breach or threatened breach of any of the restrictions set forth in Section 3 hereof will result in irreparable and continuing damage to the Company Group for which there may be no adequate remedy at law and that the Company Group shall be entitled to equitable relief, including specific performance and injunctive relief as remedies for any such breach or threatened or attempted breach. The Executive hereby consents to the grant of an injunction (temporary or otherwise) against the Executive or the entry of any other court order against the Executive prohibiting and enjoining him from violating, or directing him to comply with, any provision of Section 3 hereof. The Executive also agrees that such remedies shall be in addition to any and all remedies, including damages, available to the Company and its subsidiaries against him for such breaches or threatened or attempted breaches.

5.Mutual Non-Disparagement. From and after the Separation Date, (i) the Executive agrees not to defame or disparage, or otherwise engage in any act that is intended or may be reasonably be expected to harm the reputation, business, prospects or other operations of the Company Group, any member of their management, boards of directors or any investor or shareholder any member of the Company Group, unless as required by law or an order of a court or governmental agency with jurisdiction, and (ii) the officers and directors of the Company agree not to defame or disparage, or otherwise engage in any act that is intended or may be reasonably be expected to harm the reputation, business, prospects or other interests of the Executive, unless as required by law or an order of a court or governmental agency with jurisdiction. For the avoidance of doubt, nothing contained in this Section 5 shall prevent the Executive from engaging in competitive business activities; provided, that such activities are conducted in a manner, or at times, such that they do not violate Section 3 hereof and provided, further, that such activities do not in themselves constitute defamation or disparagement of the nature described herein. The provisions of this Section 5 shall not apply to truthful testimony as a witness, compliance with other legal obligations, assertion of or defense against any claim of breach of this Agreement, and shall not require the Parties to make false statements or disclosures.

6.Release of Claims.
