Re:       Update to License Application for Integration Earth Station in Bristow, Virginia
          File No. SES‐LIC‐20150310‐00138; Call Sign E150018

Dear Ms. Dortch:

On March 10, 2015, O3b Limited (“O3b”) submitted an application for license to operate 2
earth stations in Bristow, VA, for commercial integration, testing and demonstration
purposes.

Please find attached heretofore updated information related to O3b’s license application, as
described below.

         One part of the Form 312, Schedule B submitted by O3b on March 10, 2015, in the
          License application has been updated. Specifically, sections E56 and E57 have been
          updated. This relates only to the minimum elevation angle and associated azimuth
          angles that will be used by this earth station; the elevation and azimuth angle have
          been revised to correctly represent the values needed for operation.

Please direct any questions to the undersigned.

                                           Sincerely,

                                              /s/ Suzanne Malloy
