TRANSITION AGREEMENT AND GENERAL RELEASE

This Transition Agreement and General Release (the “Agreement”), dated December 22, 2016 (the “Effective Date), is entered into by and between Gogo LLC (the “Company”) and Norman Smagley (the “Employee”).

WHEREAS, the Employee is currently employed by the Company as its Executive Vice President and Chief Financial Officer;

WHEREAS, the Company and the Employee have agreed that following a period during which the Employee provides transition services to the Company, the Employee will separate from employment with the Company;

WHEREAS, the Employee and the Company desire to enter into an agreement regarding the Employee’s transition services and separation from employment with the Company and a release of claims;

NOW, THEREFORE, in consideration of the mutual promises and agreements contained herein and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the Company and the Employee agree as follows:

A. The Employee’s employment with the Company will terminate at the close of business on December 31, 2017 (the “Separation Date”), and the Employee will remain an employee of the Company through such date. Except as provided in Paragraph 3 and Paragraph 4, the Employee will be paid his current base salary through the Separation Date on the regularly established Company pay dates; provided, however, that if Employee commences employment with an employer other than the Company during the period between the completion of the Transition (as defined below) and the Separation Date, Employee’s salary shall be reduced by 50% effective as of the date of resignation and applicable through the Separation Date. In addition, provided that Employee does not resign his employment before cash bonuses applicable to 2016 are paid to Company employees and the Company does not terminate his employment pursuant to Paragraph 5 of this Agreement before cash bonuses applicable to 2016 are paid to Company employees, Employee will be entitled to receive such bonus, if any, with respect to 2016 which he would have received had this Agreement not been executed, less tax withholding to the extent required by law, with such payment occurring on the date on which bonuses are paid to other senior executives of the Company.

In the event of such termination the Company will continue to pay the Employee his current base pay (through the effective date of such termination) but will have no other obligations to the Employee and, in particular, will have no obligation to provide the Employee with any severance benefits described in Paragraph 2 of this Agreement or otherwise, unless and to the extent required by Section 9(a) of the Employment Agreement dated September 7, 2010 between the Company and Employee (the “Employment Agreement”).

Notwithstanding anything to the contrary contained herein, nothing in this Agreement shall be interpreted as prohibiting Employee from accepting a position from another employer and working full time for such employer (except as prohibited by Section 5 of the Employment Agreement) between the Transition Date and the Separation Date so long as Employee remains employed by Gogo and complies with the requirements of clause (2) of subparagraph B(iii), taking into account the last sentence of such subparagraph, until the Separation Date.
