Item 7.01 - Regulation FD Disclosure

On October 19, 2005, Motient Corporation filed two lawsuits against James D.
Dondero, one in the United States District Court for the Northern Division of
Texas, and one in the District Court of Dallas County, Texas. Copies of the
complaints are attached hereto as Exhibit 99.1 and 99.2.

The complaint filed in state court alleges that Mr. Dondero has seriously and
repeatedly breached his fiduciary duties as a director of Motient in order to
advance his own personal interests. The complaint filed in Federal court alleges
selective disclosure of material inside information and other improper actions
undertaken by Mr. Dondero, the net result of which have been to drive down the
price of Motient's stock. It also alleges that Mr. Dondero has solicited, and is
still soliciting, the replacement of Motient's current board and management in
violation of federal law. Mr. Dondero's latest 13D filing notes that he is
considering plans to acquire more of Motient's stock in the near future.

Motient's internal investigation of possible breaches of fiduciary duties by Mr.
Dondero has been ongoing for several months, and Mr. Dondero still has not
cooperated with this investigation.

On October 20, 2005, Motient filed a press release concerning these lawsuits, a
copy of which is attached hereto as Exhibit 99.3.

This information is furnished, not filed, pursuant to Regulation FD.
