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, 2003 (filed on
July 2, 2004) and quarterly report on Form 10-Q for the quarter ended September
30, 2004. 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 1.01  Entry Into a Material Definitive Agreement

On January 10, 2004, Motient Corporation ("Motient") entered into a binding term
sheet (the "Term Sheet") with Telcom Satellite Ventures Inc. and Telcom
Satellite Ventures II Inc. (collectively, "Telcom"), pursuant to which Telcom
will merge with and into MVH Holdings Inc. ("MVH"), a direct and wholly-owned
subsidiary of Motient, in a tax free reorganization in which MVH will be the
surviving company (the "Mergers"). Following the consummation of the Mergers,
the 2,296,835 limited partnership units of Mobile Satellite Ventures LP
(collectively with its general partner, MSV GP Inc., "MSV") held by Telcom will
be owned by MVH. In exchange for the MSV limited partnership units, Motient will
issue to Telcom's shareholders 8,187,804 shares of its common stock (the
"Motient Shares") in a private placement described further in Item 3.02 below.

This transaction will increase Motient's ownership of MSV by approximately 5.9%,
giving Motient ownership of approximately 44.5% of MSV. In addition, Motient
will also acquire the rights held by Telcom to receive shares of TerreStar
Networks Inc. ("TerreStar"), currently a wholly-owned subsidiary of MSV. If
TerreStar were to be spun off by MSV to MSV's equity holders, Motient would
obtain direct ownership of TerreStar in approximately direct proportion to its
ownership of MSV.

                                       2


Motient and Telcom anticipate that the Mergers will close in February, 2005, and
will be subject to the following terms and conditions:

          o The Mergers will need to comply with the restrictions placed upon
            the transfer of MSV interests in the various documents governing MSV
            and its equity holders, including, but not limited to, rights of
            first refusal, tag along rights, drag along rights and restrictions
            upon ownership of more than 49% of MSV. To the extent other equity
            holders of MSV exercise their tag along rights to participate in
            this offer on the same terms as outlined herein, Motient may, in its
            sole discretion, increase the offer to accommodate the holders of
            such interests who desire to exercise such tag along rights.

          o Motient will use its reasonable best efforts to cause a registration
            statement on Form S-1 (or if available S-3) relating to the resale
            of the Motient Shares to be filed with the SEC within three business
            days following the consummation of the mergers and will use its
            reasonable best efforts to cause the registration statement to
            become effective as soon as practicable after the date of such
            filing.

          o The Telcom shareholders will receive warrants (the "Warrants") in
            the form agreed to by them and Motient exercisable for an aggregate
            of 614,086 shares of Motient common stock (the "Warrant Shares").
            The Warrants will have a term of five years and an exercise price
            equal to $22.50, the closing price of Motient common stock on
            January 10, 2005. Each Warrant shall become exercisable only as
            follows: (i) with respect to 35% of the Warrant Shares, on the date
            that is 30 days following the closing of the Mergers, if a
            registration statement covering the resale of the Motient Shares
            shall not have been filed with the SEC by such date, (ii) with
            respect to an additional 35% of the Warrant Shares, on the 60th day
            after the closing of the Mergers, if a registration statement
            covering the resale of the Motient Shares shall not have been filed
            with the SEC by such date, and (iii) with respect to 30% of the
            Warrant Shares, on the 180th day after the closing of the Mergers,
            if a registration statement covering the resale of the Motient
            Shares shall not have been declared effective.

          o Telcom may not solicit other offers to purchase its interests in
            MSV.

          o Such other conditions as are customary to the signing and closing of
            a merger agreement, including the approval of Telcom's shareholders.

Due to the conditions listed above, Motient can provide no assurance that the
consummation of the transactions described herein will occur within the expected
time frame, if ever.

Item 3.02  Unregistered Sales of Equity Securities

Upon the consummation of the Mergers described in greater detail in Item 1.01
above, Motient will issue the Motient Shares and the Warrants to the Telcom
shareholders in a private placement. The consummation of the Mergers is on the
terms and subject to the conditions described in Item 1.01 above.

                                       3


Upon the consummation of the Mergers, the Motient Shares, Warrants and Warrant
Shares will not have not been registered under the Securities Act of 1933, as
amended, and therefore they may not be offered or sold in the United States
absent registration or an applicable exemption from registration requirements.
As the potential purchasers are all accredited investors, and no general
solicitation has occurred, or will occur, as part of the offering and sale of
these securities, Motient has relied upon the exemption from registration
afforded by Rule 506 under the Securities Act and/or Section 4(2) of the
Securities Act.
