This Report on Form 8-K contains forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. All statements regarding our
expected financial position and operating results, our business strategy, and
our financing plans are forward-looking statements. These statements can
sometimes be identified by our use of forward-looking words such as "may,"
"will," "anticipate," "estimate," "expect," "project," or "intend." These
forward-looking statements reflect our plans, expectations, and beliefs and,
accordingly, are subject to certain risks and uncertainties. We cannot guarantee
that any of such forward-looking statements will be realized.

Statements regarding factors that may cause actual results to differ materially
from those contemplated by such forward-looking statements ("Cautionary
Statements") include, among others, those under the caption "Risk Factors" in
our annual report on Form 10-K for the year ended December 31, 2004, our
quarterly report on Form 10-Q for the quarter ended June 30, 2005, and our
recently filed registration statements on Form S-1. All of our subsequent
written and oral forward-looking statements (or statements that may be
attributed to us) are expressly qualified by the Cautionary Statements. You
should carefully review the risk factors described in our other filings with the
Securities and Exchange Commission (the "SEC") from time to time.

Our forward-looking statements are based on information available to us today,
and we undertake no obligation to update these statements. Our actual results
may differ significantly from the results discussed.

Item 8.01  Other Events.

August 16, 2005, Highland Legacy Limited, a stockholder of Motient Corporation,
filed suit in the Court of Chancery of the State of Delaware in and for New
Castle County against: Motient Corporation; Steven Singer, Gerald Kittner, Barry
Williamson, Raymond Steele and Gerald Goldsmith, directors of Motient; Peter D.
Aquino, a former director of Motient; Christopher Downie, Chief Operating
Officer of Motient; Gary Singer; Tejas, Inc.; Tejas Securities, Inc.;
Communications Technology Advisors LLC; Capital & Technology Advisors, Inc.; and
Jared Abbruzzese. Highland Legacy Limited is an affiliate of James Dondero, a
director of Motient. The lawsuit alleges breaches of duties allegedly owed to
Motient by the defendants and seeks the recovery of fees from certain of these
parties relating to prior transactions with Motient. Most of these fees were
approved by Mr. Dondero in his capacity as a director of Motient. Also on August
16, 2005, Highland Crusader Offshore Partners, L.P., Highland Equity Focus Fund,
L.P., Highland Capital Management, L.P., and Highland Capital Management
Services, L.P., filed suit in the District Court in Dallas County, Texas,
against Motient seeking, among other remedies, rescission of their purchase of
Series A Preferred Stock of Motient in April, 2005. These four plaintiffs are
also affiliates of James Dondero, a director of Motient.

Motient understands that Mr. Dondero or his Highland entities have been
involved, primarily as a plaintiff, in over 50 lawsuits since 2002, at least
some of which are similar to the Delaware lawsuit filed on August
16. The lawsuits against Motient were filed after the formation by Motient's
Board of Directors of an Executive Committee which does not include Mr. Dondero.
Motient believes that these lawsuits have no merit and intends to vigorously
defend these lawsuits.
