TerreStar Networks Closes $200 Million Equity Financing

Mobile Satellite Ventures Spins-Off S-Band TerreStar Subsidiary to Enhance Value and Independence of Both Companies


RESTON, Va., May 11, 2005 (PRIMEZONE) -- Mobile Satellite Ventures (MSV) announced today the closing of a $200 million private placement in its former subsidiary TerreStar Networks Inc. (TerreStar). TerreStar, in partnership with TMI Communications, is one of two FCC licensees in the 2 GHz frequency band planning to develop, build and operate advanced mobile satellite services. Simultaneously with the financing, TerreStar was spun off to MSV's shareholders as a stand-alone company. Following the closing, wireless communications provider Motient Corp. becomes the majority shareholder of TerreStar with an ownership position of nearly 61% of outstanding shares. This financing, together with MSV's $230 million November financing that also resulted in the retirement of all MSV debt, establishes both MSV and TerreStar as independent developers of a new generation of communications services combining satellite ubiquity with terrestrial efficiency. TerreStar holds a license to deploy its network using MSV's unparalleled hybrid network (ATC) patent portfolio.

"This transaction provides huge benefits to both MSV and TerreStar," stated Alexander H. Good, vice chairman and chief executive officer of MSV. "As recently announced, construction of TerreStar's satellite is well underway with Space Systems/Loral. This financing enables TerreStar to continue its satellite and ground system development, while MSV dedicates the proceeds of its November financing to accelerate deployment of its next generation L-Band system. It is a win-win situation all around, not only for both companies, but also for the public interest through provision of innovative, cost-effective wireless services to consumers throughout North America."
