SKYTERRA ANNOUNCES RECEIPT OF $22.6 MILLION
AS PREPAYMENT OF MOTIENT NOTE

New York, NY July 16, 2004 — SkyTerra Communications, Inc. (OTC: SKYT) today announced the receipt of approximately $22.6 million from the Motient Corporation as payment of all outstanding principal and accrued interest due under the promissory note issued to SkyTerra by a wholly-owned subsidiary of Motient on May 1, 2002 in connection with Motient’s plan of reorganization. As reflected in SkyTerra’s public filings, because of uncertainty concerning SkyTerra’s ability to collect on the note, the note previously was written off. As a result of SkyTerra’s receipt of the payment, the $22.6 million will be reflected as income in the second quarter of 2004.

SkyTerra is currently engaged in a number of separate and preliminary discussions concerning possible transactions relating both to existing operations and the acquisition of complementary businesses, though no definitive agreements have been reached. SkyTerra expects to use its cash to support these and other future initiatives.
