("MVH"), a wholly owned subsidiary of Motient Corporation ("Motient"), purchased 700,156 shares of common stock of TerreStar Networks Inc. ("TerreStar") from TerreStar for $21.4 million pursuant to a Stock Purchase Agreement by and between MVH and TerreStar. This purchase increased Motient's ownership of TerreStar from 54.3% to 55.1% on a fully diluted basis. Robert Brumley, the President and Chief Executive Officer of TerreStar, is a member of Motient's Board of Directors. A copy of the Purchase Agreement is filed as Exhibit 10.1 to this Form 8-K. TerreStar is a development stage company in the process of building its first satellite. TerreStar plans to develop an integrated satellite and terrestrial communications network to provide continuous nationwide wireless services, including IP-based voice and high-speed data services, throughout the United States and Canada. TerreStar has contractual rights to receive, from one of its stockholders, 20 MHz of unshared spectrum throughout the United States in the 2 GHz MSS band, in two separate 10 MHz blocks of contiguous spectrum. This spectrum is eligible for ancillary terrestrial component, or ATC, authorization, under which TerreStar can integrate terrestrial wireless services with mobile satellite services, or MSS. ATC rules and policies permit the re-use of assigned satellite frequencies terrestrially in order to extend MSS availability, for example, to many indoor and urban areas where satellite signals cannot be received reliably. -2- Item 2.01 - Completion of Acquisition or Disposition of Assets The information set forth in Item 1.01 above is incorporated herein by reference.
