Agreement with the Federal Government

• Cooperative Research and Development Agreement (“CRADA”) between U.S.
Defense Information Systems Agency (“DISA”) and TerreStar concerning
TerreStar’s North American Emergency Response Communications Network

DISA-07-001
October 6, 2006

• CRADA positions TerreStar as a collaborator with the federal government regarding a
variety of public safety and defense users

• TSN believes the CRADA could provide benefit to the government in the following ways:

-	Ensure continuity of communications in event of disaster
-	Provide backup platform for command and control of federal, state and local officials

“As a result of this CRADA, DISA expects an expanded resource base of
     interoperable commercial equipment.

     Both Collaborators expect this CRADA will yield substantial progress, via
     information exchanges between DISA and TerreStar, to eventually develop
     products that will mutually benefit the Government and the collaborator. ”
