Exhibit C December 10, 2010 Ms. Angela Maimo Intelsat angela.maimo@intelsat.com Re: KA268 Paumalu, Hawaii C-band Transmit/Receive earth Station Emissions Dear Ms. Maimo, This letter is confirmation that your 9 Meter earth station licensed under Call Sign KA268 is clear for the following new Emission Designators that are to be added to the license: 256KG7W, 36M0G7W, and 72M0G7W. The transmit power densities for these new emissions are as follows: 256 kHz – EIRP: 65.56 dBW and EIRP Density: 47.5 dBW/ 4 kHz, 36 MHz – EIRP: 79.04 dBW and EIRP Density: 39.5 dBW/ 4 kHz, and 72 MHz – EIRP: 79.05 dBW and EIRP Density: 36.5 dBW/ 4 kHz These EIRP densities are less than those emissions presently licensed on the KA268, 9 meter antenna, and are accounted for in the existing coordinated parameters of the license across the range of carriers covered by these Emission Designators Please let us know if you have any questions, or require additional information on this earth station. Sincerely, Comsearch Jeffrey E. Cowles Engineer III, Telecommunications (703) 726-5660 jcowles@comsearch.com
