     WHEREAS, the Company has requested Motorola to amend certain provisions of

     WHEREAS, the parties hereto also desire to provide for the Outstanding
Account Balance herein;

     NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration and the mutual benefits, covenants and agreements herein
expressed, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:

     1. Outstanding Amounts Due on the Notes. The parties hereto agree that, as

$2,675,593.90,

<PAGE>


and the outstanding amount due under the Credit Note is $1,870,000.00, which
outstanding amounts shall constitute the outstanding amounts due under the SLA
Note and the Credit Note, respectively.

     2. Interest Rate. The parties hereto agree that, notwithstanding anything
to the contrary in any of the Credit Documents, the applicable interest rate to
the principal amounts outstanding under the SLA Note and under the Credit Note
shall bear interest at a per annum rate equal to the LIBOR Rate plus four
percent (4%), compounded quarterly. "LIBOR Rate" shall mean the one month London
Interbank Offered Rate (as published by the Wall Street Journal) in effect on
the 15th day of each calendar month. Interest shall be computed through the
Business Day immediately preceding the day on which payment is due under the SLA
Note or the Credit Note and Credit Agreement, as applicable. "Business Day"
shall mean a day other than Saturday, Sunday or any other day on which
commercial banks in Illinois are authorized or required by law to close.
Interest shall be calculated on a 360 day basis for actual days elapsed

shall not waive the Lenders' rights to receive interest at an increased rate
following a default in accordance with the terms of the SLA Note or the Credit
Note and Credit Agreement, as applicable.

     3. Payments. The parties hereto agree that, notwithstanding anything to the
contrary in any of the Credit Documents, the SLA Note and the Credit Note will
be payable in monthly installments on the 1st day of each month commencing April
1, 2004. Each installment shall be in an amount equal to (i) $100,000 to reduce
the principal outstanding under each of the SLA Note and the Credit Note and
which shall be applied to such notes on a pro rata basis in accordance with
their respective principal balances plus (ii) all accrued, unpaid interest on
the SLA Note and the Credit Note. Partial payments shall be applied by Motorola
pro rata to the SLA Note and the Credit Note in accordance with their respective
principal balances and shall be applied first to accrued, unpaid interest and
then to principal in direct order of payment. The parties hereto further agree
that the Company shall pay $75,000 per week on the first business day of each
week, commencing on April 1, 2004, to be applied toward repayment of the
Outstanding Account Balance until the Outstanding Account Balance is paid in
full. No failure by the Company to make any payment required by the immediately
preceding sentence shall constitute a default under any agreement or other
instrument of indebtedness of the Company solely by virtue of this Amendment,
though such a default would constitute a default under this Amendment.

     4. Ratification. Each of the Company and each Guarantor hereby ratifies all
of its Obligations (as defined in the Credit Agreement) and other obligations
under the Credit Documents to which it is a party and the Settlement and Release

among Motorola, Motorola Credit Corporation, the Company and Motient
Corporation, and agrees and acknowledges that the Credit Documents and the
Settlement Agreement to which it is a party shall continue in full force and
effect giving effect to this Amendment. Nothing in this Amendment extinguishes,
novates or releases any right, claim, lien, security interest or entitlement of
Motorola created by or contained in any of such documents nor is such individual
or entity released from any covenant, warranty or obligation created by or
contained herein.

     5. Representations and Warranties. Each of the Company and each Guarantor
hereby represents and warrants to Motorola that (a) this Amendment has been duly


                                       2

accordance with its terms, (c) upon the execution of and after giving effect to
this Amendment by all parties, no default or event of default exists under the
Credit Documents and (d) the execution, delivery and performance of this
Amendment has been duly authorized by each of the Company and each Guarantor,
respectively.

     6. Conditions to Effectiveness. This Amendment shall be effective upon (i)
the execution and delivery hereof by all parties and delivery to Motorola, (ii)
receipt by Motorola of a fully executed copy of a Subordinate Motient
Communications Share Pledge Agreement whereby the Company pledges all of its
interest in Motient License Inc., which agreement shall be in form and substance
satisfactory to Motorola and (iii) any other items or information as may be
required by Motorola.

     7. Release and Indemnity. (a) The Company shall and hereby does release and
indemnify Motorola, each affiliate thereof and their respective directors,
officers, employees and agents against, and release and hold each of them
harmless from any and all losses, liabilities, claims or damages (including
reasonable legal fees and expenses) to which any of them may become subject,
insofar as such losses, liabilities, claims or damages arise out of or result
from the Credit Documents, this Amendment or any of the transactions
contemplated thereby (including any threatened investigation or proceeding)
relating to the foregoing. The Company shall reimburse Motorola and each
affiliate thereof and their respective directors, officers, employees and
agents, upon demand for any expenses (including legal fees) reasonably incurred
in connection with any such investigation or proceeding; but excluding any such
losses liabilities, claims, damages or expenses incurred by reason of the gross
negligence or willful misconduct of the individual or entity to be indemnified
(the "Indemnified Obligations").

     (b) Without limiting any provision of this Amendment, it is the express
intention of the parties hereto that each individual or entity to be indemnified
hereunder shall be indemnified and held harmless against any and all Indemnified
Obligations arising out of or resulting from the ordinary sole or contributory
negligence of such individual or entity or imposed upon said party under any
theory of strict liability. Without prejudice to the survival of any other
obligations of the Company hereunder and under the other Credit Documents, the
obligations of the Company under this Section shall survive the termination of
this Amendment, the Credit Documents and the payment of all obligations
thereunder.

     8. Counterparts. This Amendment may be signed in any number of
counterparts, which may be delivered in original or facsimile form, each of
which shall be construed as an original, but all of which together shall
constitute one and the same instrument.

     9. Additional Documents. The parties hereto agree that they will execute
such further documentation as may be necessary to comply with or accomplish the
agreements set forth herein.

     10. Governing Law. This Amendment, all Notes, the other Credit Documents
and all other documents executed in connection herewith shall be deemed to be
contracts and agreements under the laws of the State of Illinois and of the
United States of America and for all purposes shall be construed in accordance
with, and governed by, the laws of the State of Illinois and of the United
