               Motient Announces Terms of Proposed Rights Offering

LINCOLNSHIRE, IL, November 22, 2004 -- Motient Corporation (MNCP) announced
today the terms of a proposed common stock rights offering. Motient will issue
to its stockholders one right for each share of Motient common stock held as of
the close of business on December 10, 2004. Each right will entitle any holder
that did not participate in the November 12, 2004 private placement of Motient
common stock to purchase 0.103 shares of Motient's common stock at a price of
$8.57 per share, with fractions rounded up to the next whole share. Assuming
full participation in the rights offering by stockholders who have not
previously waived their right to participate, Motient estimates that it would
issue up to 2.45 million shares of common stock, generating aggregate proceeds
of up to $21 million, in the rights offering. Motient currently has
approximately 56.5 million shares of common stock outstanding on a fully diluted
basis.

If fewer stockholders participate, the aggregate proceeds will be less. These
estimates are based on publicly available information regarding the holdings of
purchasers of Motient's common stock in the November 12, 2004 private placement
and their affiliates, and assumes that holders of currently exercisable warrants
will exercise such warrants prior to the record date if the holder would be
eligible to participate upon exercise.

The rights will be non-transferable and will expire if not exercised within the
exercise period. The rights will not be exercisable until the registration
statement covering the rights and the shares of underlying common stock is
declared effective by the SEC, and the exercise period will expire 30 days after
the rights become exercisable. Motient has not filed a registration statement
relating to the rights offering, but intends to do so as soon as practicable.

The holders of the rights will not have over-subscription rights, and there will
be no backstop to purchase unsubscribed shares. Purchasers that purchased shares
in the November 12, 2004, private placement of Motient's common stock have
waived their rights to participate in the rights offering.

Motient reserves the right to abandon this rights offering at any time prior to
the effectiveness of the registration statement relating to the rights offering,
and upon any such abandonment, any and all of the rights previously issued will
be cancelled, will no longer be exercisable and will be of no further force or
effect.

                                       1


These securities may not be sold nor may offers to buy be accepted prior to the
time the registration statement becomes effective. This press release shall not
constitute an offer to sell or the solicitation of an offer to buy nor shall
there be any sale of these securities in any state or jurisdiction in which such
offer, solicitation or sale would be unlawful prior to registration or
qualification under the securities laws of any such state or jurisdiction.
Nothing in this press release should be construed as investment advice or
otherwise as an invitation to engage in investment activity.

No prospectus related to the rights offering has been, or will be, filed for
registration with any authority outside of the United States. The rights and
shares of common stock are not being offered or sold to any person outside the
United States.
