Exhibit C Description of Application LightSquared Subsidiary LLC (“LightSquared”) hereby requests authority to extend the MSAT-2 license term for one year until December 31, 2013.1 LightSquared has launched and commenced operations of SkyTerra 1, the replacement satellite for MSAT-2.2 Nearly all customers continuing service on SkyTerra 1 have been transitioned successfully to the replacement satellite. A few customers, whose transition to SkyTerra 1 has been delayed for technical reasons, will be transitioned over the next few months.3 Further, MSAT-2 remains suitable as a back-up satellite for SkyTerra 1 customers, some of which provide service to government and public safety entities. Indeed, the ability of MSAT-2 to provide restoral service was demonstrated earlier this year when traffic on SkyTerra 1 was restored on MSAT-2, following the temporary upset of SkyTerra 1 by unusually intense solar activity.4 Accordingly, for these reasons, LightSquared seeks an extension of the MSAT-2 license. LightSquared proposes no changes to the technical operations of MSAT-2 and has completed coordination of the satellite’s operations for the extended period with all affected satellite operators. The proposed license extension does not impact the orbital debris mitigation plan for the satellite. LightSquared has confirmed that at the conclusion of the requested extension period MSAT-2 will have sufficient fuel to de-orbit to a 1 The license for MSAT-2 expires on December 31, 2012.

Dortch, Call Sign S2358 (January 21, 2011). 3 As an additional consideration, one customer for technical reasons (i.e. the return carriers are not compatible with SkyTerra 1) cannot be transitioned and will continue to be served on MSAT-2 while it is operational. 4 See Annual Satellite Status Report, Letter from Jeffrey Carlisle, Executive Vice President, LightSquared, to Mindel De La Torre, Chief, International Bureau, Call Sign AMSC-1 and S2358 (June 29, 2012). 403731796v2
