of any such proceeding brought in such court and any claim that any such
proceeding brought in such court has been brought in an inconvenient forum.

            Schedule of Exceptions to Representations and Warranties

Section 4.03 - FCC will be notified subsequent to the transfer of FCC Licenses
from Motient Communications Inc. to Motient License Inc. No formal FCC approval
is required.

Section 4.06 - See Annex D

Section 4.11 - Motient License Inc. is a subsidiary of Motient Communications
        Inc.

Section 4.13 - Since January 27, 2003 there have been a number of developments
regarding Motient's business, assets, operations, prospects and condition. Some
of these developments and changes may constitute a Material Adverse Effect:

     1. Change in Accountants:

          On March 2, 2004 Motient Corporation dismissed PricewaterhouseCoopers
     LLP ("PwC") as its independent accountants, effective immediately. PwC had
     been previously dismissed on April 17, 2003 with respect to all accounting
     periods other than the period from May 1, 2002 to December 31, 2002.

     2. Failure to File 2002/2003 Reports:

          Motient Corporation failed to timely file its reports on form 10-Q and
     10-K for the year 2002, and its reports on form 10-Q for the year 2003.
     Motient does not expect to timely file its report on form 10-K for the year
     2003 or its report on form 10-Q for the first quarter of the year 2004.
     Consequently, Motient Corporation's outstanding shares of common stock are
     not registered.

     3. UPS:

          United Parcel Service ("UPS"), the Borrower's largest customer, has
     begun a planned partial migration to next generation network technology
     causing its monthly airtime usage of the Borrower's network to decline.
     Although UPS signed a long-term contract extension with the Borrower in May
     2003, there are no minimum purchase requirements under the contract and the
     contract may be terminated by UPS on 30 days' notice. Over time the
     Borrower expects that the bulk of UPS's units will migrate to another
     network. Until June of 2003, UPS had maintained its historical level of
     payments to mitigate the near-term revenue and cash flow impact of its
     recent and anticipated continued reduced network usage. However, beginning
     in July of 2003, the revenues and cash flow from UPS have declined
     significantly. Also, due to an arrangement entered into in December 2002
     under which UPS prepaid for network airtime to be used by it in 2004, the
     Borrower does not expect that UPS will be required to make any cash
     payments to the Borrower in 2004 for service to be provided in 2004.

                                      H-1

     4. Restatement of Prior Period Financial Statements:

          Motient Corporation's ("Motient") financial information for the period
     January 1, 2002 to April 30, 2002, prior to the adoption of "fresh start"
     accounting, includes the effects of several complex transactions from prior
     years, including the formation of and transactions with a joint venture
     with Mobile Satellite Ventures LP ("MSV") in 2000 and 2001 and the sale of
     certain of Motient's transportation assets to Aether Systems, Inc.
     ("Aether") in 2000.

          In November 2002 Motient initiated a process to seek the concurrence
     of the staff of the Securities and Exchange Commission ("SEC") with respect
     to its conclusions on the appropriate accounting for these transactions,
     which was completed in March of 2003. The staff of the SEC did not object
     to certain aspects of Motient's prior accounting with respect to the MSV
     and Aether matters in 2000 and 2001, but did object to other aspects of
     Motient's prior accounting for these transactions. The required adjustments
     to reflect the appropriate accounting treatment will cause material changes
     to Motient's financial statements in our previously reported results for
     the years ended December 31, 2000 and 2001 and the three months ended March
     31, 2002.

          The following is a brief description of the material differences
     between Motient's original accounting treatment with respect to the MSV and
     Aether transactions and the revised accounting treatment that Motient has
     concluded is appropriate:

          Allocation of initial proceeds from MSV formation transactions in June
     2000. In the June 2000 transaction with MSV, Motient received $44 million
     from MSV. This amount represented payments due under a research and
     development agreement, a deposit on the purchase of certain of Motient's
     assets at a future date, and payment for a right for certain of the
     investors in MSV to convert their ownership in MSV into shares of common
     stock of Motient. Since the combined fair value of the three components
     exceeded $44 million, based on valuations of each component, Motient
     initially allocated the $44 million of proceeds first to the fair value of
     the research and development agreement and then the remaining value to the
     asset deposit and investor conversion option based on their relative fair
     values. Upon review, we have determined to allocate the $44 million of
     proceeds first to the investor conversion option based on its fair value,
     with the remainder to the research and development agreement and asset
     deposit based on their relative fair values. The effect of this
     reallocation is to increase shareholders' equity at the time of the initial
     recording, as well as to reduce subsequent service revenue as a result of
     the lower recorded value allocated to the research and development
     agreement.

          Recording of suspended losses associated with MSV in fourth quarter of
     2001. In November 2001, when the asset sale described above was
     consummated, Motient and MSV amended the agreement, with Motient agreeing
     to take a $15 million note as part of the consideration for the sale of the
     assets to MSV. Additionally, at the time of this transaction, Motient
     purchased a $2.5 million convertible note from MSV. As Motient had no prior
     basis in its investment in MSV, Motient had not recorded any prior equity
     method losses associated with its investment in MSV. When Motient agreed to
     take the $15 million note as partial consideration for the assets sold to
     MSV, Motient recorded its share of the MSV losses that had not been
     previously recognized by Motient, having the affect of completely writing
     off the notes receivable in 2001.

                                      H-2

<PAGE>

          Upon review, Motient has determined that it should not have recorded
     any suspended losses of MSV, since those losses would have been absorbed by
     certain of the senior equity holders in MSV. As a result, Motient has
     concluded that it should not have written off any prior MSV losses against
     the value of the notes in 2001.

          Recording of increase in Motient's investment in MSV in November 2001.
     Also in the November 2001 transaction, MSV acquired assets from another
     company, TMI Communications & Company ("TMI"), in exchange for cash, a note
     and equity in MSV. Motient initially considered whether or not a step-up in
     the value of its investment in MSV was appropriate for the value allocated
     to TMI for its equity interest, and determined that a step-up was not
     appropriate. Upon review, Motient has determined that it should have
     recognized a step-up in value of the MSV investment under Staff Accounting
     Bulleting No. 51, Accounting for Sales of Stock of a Subsidiary, and an
     offsetting gain recorded directly to shareholders' equity.

          Recognition of gain on sale of assets to MSV in November 2001. Upon
     the completion of the November 2001 transactions, Motient determined that
     80% of its gain from the sale of the assets should be deferred, since that
     was Motient's equity ownership percentage in MSV at the time the assets
     were sold to MSV. Upon review, Motient has determined that it was
     appropriate to apply Motient's ownership percentage at the completion of
     all of the related transactions that occurred on the same day as the asset
     sale transaction, since they were dependent upon one another and
     effectively closed simultaneously. Accordingly, Motient should have
     deferred approximately 48% of the gain (Motient's equity ownership
     percentage in MSV following the completion of such transactions) as opposed
     to 80%.

          Allocation of proceeds from the sale of the transportation business to
     Aether in November 2000. Motient received approximately $45 million for the
     sale of its retail transportation business assets to Aether. This consisted
     of $30 million for the assets, of which $10 million was held in an escrow
     account which was subsequently released in the fourth quarter of 2001 upon
     the satisfaction of certain conditions, and $15 million for a perpetual
     license to use and modify any intellectual property owned by or licensed by
     Motient in connection with the retail transportation business. In the
     fourth quarter of 2000, Motient recognized a gain of $5.7 million, which
     represented the difference between the net book value of the assets sold
     and the $20 million cash portion of the purchase price for the assets
     received at closing. Motient recognized an additional $8.3 million gain in
     the fourth quarter of 2001 when the additional $10 million of proceeds were
     released from escrow. The $1.7 million difference between the proceeds
     received and the gain recognized is a result of pricing modifications that
     were made at the time of the release of the escrow plus certain
     compensation paid to former employees of the transportation business as a
     result of the certain performance criteria having been met.

                                      H-3

<PAGE>

          Motient deferred the $15 million perpetual license payment, which was
     then amortized into revenue over a 5-year period, which was the estimated
     life of the customer contracts sold to Aether at the time of the
     transaction. Upon review, Motient has determined that the $15 million in
     deferred revenue should be recognized over a four year period, which
     represents the life of a network airtime agreement that Motient entered
     into with Aether at the time of the closing of the asset sale.

          Recognition of costs associated with certain options granted to
     Motient employees who were subsequently transferred to Aether upon
     consummation of the sale of Motient's transportation business to Aether in
     September 2000. Motient valued the vested options based on their fair value
     at the date of the consummation of the asset sale and recorded that value
     against the gain on the sale of the assets to Aether. Upon review, Motient
     has determined to value these vested options as a repricing under the
     intrinsic value method, with any charge recorded as an operating expense.
     In addition, for each subsequent quarter for which the unvested options
     continued to vest, Motient had valued these options on a fair value basis
     and recorded any adjustment in value as an operating expense. Upon review,
     Motient has determined that any adjustments in value should have been
     reflected as an increase or reduction of the gain on the sale of the assets
     to Aether.

     5. Walter V. Purnell, Jr.:

          On February 10, 2004, Walter V. Purnell, Jr. and the Company mutually
     ended his employment as President and Chief Executive Officer of Motient
     Corporation and all of its wholly owned subsidiaries. Concurrently, he
     resigned as a director of such entities and of Mobile Satellite Ventures LP
     and all of its subsidiaries.

     6. Reduction in Force:

          On February 18, 2004, Borrower effected a reduction in its workforce
     in order to reduce operating expenses and thereby preserve cash. In this
     action, 53 employees were terminated, reducing Borrower's total workforce
     from 165 employees to 112 employees. Included in this RIF were several
     executives, including the Senior Vice-Presidents in charge of Marketing and
     Sales.

     7. Accounting Controls:

          Prior to its termination, PwC informed Motient that, with regard to
     their audit of Motient's consolidated financial statements for the period
     May 1, 2002 to December 31, 2002:

         - Timely reconciliation of certain accounts between the general ledger
         and subsidiary ledger, in particular accounts receivable and fixed
         assets, was not performed;

         - Review of accounts and adjustments by supervisory personnel on
         monthly cut-off dates, in particular fixed asset clearing accounts,
         accounts receivable reserve and inventory reserve calculations, were
         not performed;

         - Cut-off of accounts at balance sheet dates related to accounts
         payables, accrued expenses and inventories was not achieved; and

         - No formal policy existed to analyze impairment of long-lived assets
         on a recurring basis.

          To address such matters, PwC recommended that management institute a
     thorough close-out process, including a detailed review of the financial
     statements, comparing budget to actual and current period to prior period
     to determine any unusual items. PwC also recommended that the Company
     prepare an accounting policy and procedures manual for all significant
     transactions to include procedures for revenue recognition, inventory
     allowances, accounts receivable allowance, and accruals, among other
     policies.

          In addition to the above, since April 2003 Borrower has reevaluated
     its staffing levels, reorganized the finance and accounting organization
     and replaced ten accounting personnel with more experienced accounting
     personnel, including, among others, a new chief financial officer, chief
     accounting officer and corporate controller, a manager of revenue assurance
     and a manager of financial services.

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

this Amendment, the Credit Documents and the payment of all obligations
thereunder.

such further documentation as may be necessary to comply with or accomplish the
agreements set forth herein.
