Item 4. Purpose of Transaction.

The Reporting Persons have acquired their Shares for investment. The Reporting
Persons evaluate their investment in the Shares on a continual basis. Other than
as expressly set forth below, the Reporting Persons have no plans or proposals
as of the date of this filing which relate to, or would result in, any of the
actions enumerated in Item 4 of the instructions to Schedule 13D.

On December 15, 2007, Harbinger Capital Partners Master Fund I, Ltd. and
Harbinger Capital Special Situations Fund, LP (together, "Harbinger") entered
into a Securities Purchase Agreement (the "Securities Purchase Agreement") with
the Issuer, Mobile Satellite Ventures LP ("MSV") and Mobile Satellite Ventures
Finance Co. ("MSV Finance Co." and together with MSV, collectively the "Note
Issuers")), pursuant to which Harbinger agreed to purchase, for $150 million,
$150 million of the Note Issuers' Senior Unsecured Notes due 2013 (the "Notes")
and ten year warrants (the "Warrants") to purchase 9,144,038 shares of the
Issuer's common stock ("Common Stock"), with an exercise price of $10.00 per
share. The terms of the Warrants permit Harbinger to elect to receive shares of
voting Common Stock, non-voting Common Stock or any combination thereof. The
transactions contemplated by the Securities Purchase Agreement closed on January
7, 2008.

The Securities Purchase Agreement grants to Harbinger the right of first
negotiation to discuss the issuance of additional equity securities by the
Issuer in private placement financing transactions. Should the Issuer and
Harbinger not agree on the terms for such a transaction, Harbinger has the right
to maintain their percentage ownership interest through pro rata purchases of
shares in issuances to third parties (subject to a number of exceptions).

The Notes were issued pursuant to an indenture (the "Indenture") that contains
restrictive covenants and events of default similar to the indenture governing
the Note Issuers' existing 14 percent Senior Secured Discount Notes due 2013
(the "Existing High Yield Indenture"). The Securities Purchase Agreement also
contains more restrictive covenants regarding mergers, consolidation and
transfer of assets and restricted payments. The more restrictive covenants, the
right of first negotiation and the pre-emptive rights expire once Harbinger and
their affiliates beneficially own less than five percent (5%) of the outstanding
Common Stock of the Issuer or, if earlier, on December 31, 2011.

The Securities Purchase Agreement contains customary representations, warranties
and closing conditions. A copy of the Securities Purchase Agreement is filed as
Exhibit C hereto and is incorporated herein by reference. A copy of the
Indenture is filed as Exhibit D hereto and is incorporated herein by reference.

The Reporting Persons reserve the right to be in contact with members of the
Issuer's management, the members of the Issuer's Board of Directors, other
significant stockholders and others regarding alternatives that the Issuer could
employ to increase shareholder value.

The Reporting Persons reserve the right to effect transactions that would change
the number of shares they may be deemed to beneficially own.

The Reporting Persons further reserve the right to act in concert with any other
stockholders of the Issuer, or other persons, for a common purpose should it
determine to do so, and/or to recommend courses of action to the Issuer's
management, the Issuer's Board of Directors, the Issuer's stockholders and
others.
