CONTRACT#: 104149-0000

SERVICE ORDER

This Service Order is submitted by Gogo LLC (“Customer”) to New Skies Satellites B.V. (“SES”) in accordance with the terms and conditions of that certain Master Services Agreement executed between Customer and SES dated 17 August, 2012, as amended by Amendment No. 1 dated 30 November, 2012 (the “MSA”).

SES shall provide Customer with the satellite services in accordance with the Service Specifications set forth below (“Service”).

SES Fleet Satellite: The SES Satellite utilized to provide the Service is an SES Global Fleet Satellite.

[***]

CONTRACT#: 104149-0000

[***]

Additional Service Specifications are contained in Attachment A to this Service Order.

Commencement Date: The Commencement Date will be the commercial operation date of the Service, as declared by SES after the successful launch, testing, and in-orbit deployment of the Satellite at the Orbital Location. SES will keep Customer reasonably apprised on the status of the satellite including the estimated Commencement Date and provide notice to the Customer of the actual date that the satellite is available for commercial operation.

End Date: On the date that is the tenth (10^th) anniversary of the Commencement Date.

Monthly Service Fee: The monthly Service Fee will be based on the applicable rate set forth in Attachment B to this Service Order. Customer shall make each and every payment monthly in advance, on or before the last business day of the month preceding the month in which Service is provided, and all such payments shall be made without offset, withholding or deduction of any kind.

[***]

The Service Fee payment conditions and Security have been agreed between the Parties based on Customer’s credit rating at the time of execution of this Service Order. Delays in the fulfillment of Customer’s obligations (including required payments due upon execution) may cause delays in the commencement of Service, but will not delay the Commencement Date for payment purposes.

Capture Team. In a side letter being entered into concurrently with the execution of this Service Order, each Party is designating a minimum of three (3) contacts each to be part of a team (the “Capture Team”) which will coordinate items of mutual interest pertaining to the Service, including capacity requirements and availability, satellite topology and restoration capability with respect to beams used or considered for the Service, technical and operational implementation, issue resolution, and SES’s nominal fleet deployment plans to replace the Satellite, whether upon a launch failure, at end of life or otherwise. One or more of a Party’s designated contacts may be changed upon notice to the other Party and such notice will designate a replacement person at an equivalent level. The Capture Team shall meet at least two (2) times per calendar year or as otherwise agreed by the Parties, and shall meet reasonably promptly upon the request of either Party.

Confirmed Outage: SES will provide Customer with a [***] plan within [***] of an unresolved Confirmed Outage.[***]. The rights under this paragraph are in addition to the Parties’ termination rights under Subsection 8(a) of the MSA.

CONTRACT#: 104149-0000

[***]

Teleport Services: SES agrees to provide teleport services reasonably sufficient to support the Service. [***]. In the negotiation of the definitive agreement for such teleport services, the Parties agree to discuss, in good faith, the possible mitigation of additional costs and expenses, provided that Customer understands and agrees that (a) such mitigation efforts may not be successful, and (b) the absence of mitigation efforts will not excuse the execution of the definitive agreements for teleport services. The agreement between the Parties regarding teleport services will be set forth in a separate Service Order, under the terms and conditions of the MSA and consistent with this paragraph. If the Parties cannot agree on terms other than those set forth in this paragraph, such terms will be generally consistent with existing terms and conditions between the Parties with respect to teleport services.

Health Reports: SES will provide Customer with a report, no less frequently than each calendar quarter during the Service Term, on the health status of the Satellite, highlighting any health status changes from the prior quarterly report.

[***]

[***]

[***]

Service Order ###-###-####: Within thirty (30) Days of countersignature of this Service Order or the SES-15 Service Order, whichever is later, the Parties will amend Service Order ###-###-####, dated 20 January 2016, under which Customer may elect to [***]. The amendment will be effective as of the date of countersignature of this Service Order or the SES-15 Service Order, whichever is later.

[***].

Licensing and Coordination:[***]

Acknowledgments: Customer acknowledges that the Satellite has not been launched at the time of execution of this Service Order. SES does not assume any liability or obligation in the event the commencement of the Service is for any reason delayed or modified or does not occur. Customer acknowledges and agrees that it shall not be entitled to seek specific performance to compel SES to cause any satellite (whether or not in orbit), including SES-15, to be constructed, launched or made commercially operational at any orbital location. The Parties acknowledge that (i) the Satellite is a SES Global Fleet Satellite and the provisions of Appendix C (Additional Terms and Definitions for North American Fleet Satellites) of the MSA do not apply to this Service Order; (ii) the provisions in Section 1 (Service Orders) of the MSA regarding third party terms and conditions are not applicable to this Service Order (except to the extent third party teleport services are contracted as contemplated herein); and (iii) for purposes of this Service Order, the term “available” and “availability” mean as determined by SES in its sole discretion.

Conditions: This Agreement is subject to the Parties’ execution of the SES-15 Service Order, on or before the execution date of this Service Order, failing which this Agreement shall be void ab initio and the Parties shall have no further obligations or liabilities to each other under this Agreement.

The services ordered pursuant to this Service Order are provided subject to the terms and conditions described in the MSA, including the applicable appendices attached thereto. Termination of the MSA will not affect the performance obligations of the Parties with respect to this Service Order or the applicability of the terms and conditions set forth in the MSA to this Service Order.

ATTACHMENT B: MONTHLY SERVICE FEES

ATTACHMENT A: SERVICE SPECIFICATIONS FOR CAPACITY ON SES-14

This attachment contains the Service Specifications for the Capacity on SES-14. The performance and configurations identified in this attachment are subject to variation, and may be updated as appropriate throughout the satellite construction program and through in-orbit testing. However, notwithstanding the prior sentence, or any other references in this Attachment A to updating or adjustment of performance, configuration or other specifications relating to SES-14 or set forth herein, to the extent such updates or adjustments are made or proposed to be made which would reduce the performance or configuration of SES-14 used to provide the Service below the values set forth in this Attachment A, [***]. For the avoidance of doubt, any changes to the [***] are subject to the mutual written agreement of the Parties.

Following execution by both Parties of this Service Order, [***]
