Motient Announces Certified Shareholder Vote Results; All Motient Board Nominees Elected.

LINCOLNSHIRE, Ill. -- Motient Corporation (MNCP) announced today the certified results of its shareholder vote to elect all of the Company's six nominees to the Board of Directors at its 2006 Annual Meeting of Stockholders held on July 12, 2006. The final voting results, certified by the independent inspectors of election, IVS Associates, Inc. show that approximately 80% percent of votes cast were in favor of Motient's Director Nominees. Approximately 16% - 20% of votes cast were in favor of Highland Capital's nominees, and about half of those votes (10% of the total) voted in favor of Highland's nominees were made by Highland and its affiliates. Shareholders also approved the adoption of the Company's Equity Incentive Plan, the amendment to the Company's restated Certificate of Incorporation and ratified the appointment of Friedman LLP as Motient's independent auditors.

"We are pleased with the results," said Christopher Downie, Motient's Chief Operating Officer. "Now that Highland's proxy challenge is officially over, we can concentrate our full attention on the business of Motient and its subsidiaries. In that vein, today we are filing a registration statement with the SEC to register Motient shares that we will exchange for TerreStar shares held by some of TerreStar's minority holders - a necessary condition to closing our MSV and TerreStar exchange transactions. In addition, as the majority owners of TerreStar, we are working diligently with TerreStar management to implement TerreStar's business plan. We think TerreStar is a great company, they have already made great strides in their development of a integrated satellite-terrestrial communications network and we look forward to consolidating and expanding our ownership of TerreStar."
