Motient Corporation Announces Results of Internal Investigation

Audit Committee Concludes that Board Member's Allegations are Without Merit

October 6, 2005 - Lincolnshire, IL - Motient Corporation (MNCP) today announced
that the audit committee of its board of directors, assisted by its independent
special counsel, has concluded an internal investigation that it began in July
2005 to investigate the validity of allegations made by investor and board
member James D. Dondero concerning certain members of the company's current and
former board, certain members of management, and certain consultants and
advisors, and has found the allegations to be completely baseless,
unsubstantiated, and without merit.

Motient's board instructed the audit committee to commence its investigation
after the committee, in June 2005, received a letter from Mr. Dondero setting
forth his allegations. The board gave the audit committee full freedom and
authority to conduct an objective, comprehensive review of all of Mr. Dondero's
allegations, and also requested that Mr. Dondero provide the audit committee
with any evidence he had substantiating those allegations. Despite the board's
repeated requests, and Mr. Dondero's repeated promises to do so, Mr. Dondero
failed to produce any material evidence. Nevertheless, the committee proceeded
with its inquiry.

As part of this comprehensive inquiry, the audit committee retained independent
special counsel, distributed written requests for information, reviewed company
documents and other evidence, and conducted multiple interviews. Based on this
report, the committee concluded that Mr. Dondero's allegations were objectively
refutable and without merit, and cleared all of the subjects of Mr. Dondero's
allegations of any wrongdoing.

Mr. Dondero's allegations came shortly after the board's decision to restructure
its committees to comply with NASDAQ listing requirements regarding
disinterested directors. As part of this restructuring effort, the board
determined that under NASDAQ rules, Mr. Dondero was not eligible to remain a
member of the board's compensation committee. Mr. Dondero objected to this
decision and unsuccessfully demanded that he be reinstated to the compensation
committee. He then placed telephone calls to several Motient investors, during
which he admittedly discussed matters concerning Motient that the board believes
may have included his inappropriate disclosure of material, nonpublic
information. When the board was apprised of this conduct, it immediately
responded by instructing its nominating committee to further investigate Mr.
Dondero's conduct. This investigation remains open while the nominating
committee awaits Mr. Dondero's response to the nominating committee's
long-outstanding and repeated requests for information.



Shortly after Mr. Dondero prompted the nominating committee's investigation
concerning Mr. Dondero's conduct, Mr. Dondero's investment companies--Highland
Capital Management and certain of its affiliates that are Motient
shareholders--filed three lawsuits against Motient and other defendants.
Highland's lawsuit against certain Motient directors, officers, and consultants
was purportedly filed on Motient's behalf and involves the same allegations Mr.
Dondero brought to the audit committee's attention in June. The other two
lawsuits, filed against Motient and Motient's outside counsel, seek damages
allegedly suffered because Mr. Dondero's companies claim to have been damaged by
their purchase of Motient preferred stock. All defendants in these cases have
retained outside counsel and intend to vigorously defend against all of
Highland's allegations.

Robert Macklin, Motient's General Counsel, said, "Motient is disappointed that
Mr. Dondero opted to lodge unsubstantiated allegations and initiate wasteful
litigation at the expense of Motient's shareholders. Now that the audit
committee has completed its comprehensive internal investigation, we call upon
Mr. Dondero to immediately withdraw his lawsuits and cooperate with the
nominating committee's separate ongoing investigation into his conduct."
