SES reserves the right to declare any deferred amounts immediately due and payable upon the failure of Gogo or its affiliates to make timely payments to SES or its affiliates under the terms and conditions of the agreements.

All deferred amounts are immediately due and payable upon the change of control of Gogo or any of its business units. Change of control shall mean the occurrence of any of the following events: (i) an acquisition of Gogo or any of its business units by another entity by means of any transaction or series of related transactions, or (ii) a sale of all or substantially all of the assets of Gogo or any of its business units, so long as in either case the stockholders of record immediately prior to such event will, immediately after such event, hold less than fifty percent (50%) of the voting power of the surviving or acquiring entity or business.

The deferrals exclude the ramp capacity associated with SES-14 and SES-15 and any pay­ ment relief related to those ramps will be addressed separately.

SES is committed to the long-term success of our relationship and we look forward to working with Gogo on future opportunities.

Yours sincerely,Acknowledged and Agreed by Gogo LLC:
