                      MOTIENT CORPORATION AND SUBSIDIARIES

              Notes to Consolidated Condensed Financial Statements
                                 March 31, 2001
                                   (Unaudited)


1.       ORGANIZATION AND BUSINESS

Motient  Corporation  (with its  subsidiaries,  "Motient" or the "Company") is a
leading  provider  of two-way  mobile  communications  services  principally  to
business-to-business  customers  and  enterprises.  Motient  serves a variety of
markets  including  mobile  professionals,   telemetry,   transportation,  field
service,  and nationwide  voice dispatch.  Motient  provides its eLink(sm) brand
two-way wireless email services to customers  accessing email through  corporate
servers,  Internet  Service  Providers  ("ISP"),  Mail Service  Provider ("MSP")
accounts,  and paging network suppliers.  In November 2000, Motient launched its
BlackBerry  TM by Motient  wireless  email  solution,  developed  by Research in
Motion  ("RIM") and licensed to operate on Motient's  network.  BlackBerry TM by
Motient is  designed  for large  corporate  accounts  operating  in a  Microsoft
Exchange  environment and contains advanced encryption features.  Together,  the
Company  considers these two-way mobile  communications  services to be its Core
Wireless Business.

Motient is devoting its efforts to expanding  its Core Wireless  Business.  This
effort involves  substantial  risk.  Future operating results will be subject to
significant  business,   economic,   regulatory,   technical,   and  competitive
uncertainties  and  contingencies.  Depending on their extent and timing,  these
factors,  individually or in the aggregate,  could have an adverse effect on the
Company's financial condition and future results of operations.

XM Radio

Additionally,  as  of  March  31,  2001,  Motient  had  an  equity  interest  of
approximately  25.3% (or 15% on a fully  diluted  basis) in XM  Satellite  Radio
Holdings Inc. ("XM Radio"), a public company;  however,  as of December 31, 2000
the Company controlled XM Radio through Board of Director  membership and common
stock voting  rights.  As a result,  all of XM Radio's  results for the calendar
year 2000 have been included in the Company's consolidated financial statements.

In January 2001, pursuant to Federal Communications  Commission ("FCC") approval
authorizing  Motient to relinquish  control of XM Radio, the number of directors
appointed by the Company to XM Radio's  Board of  Directors  was reduced to less
than 50% of XM Radio  directors,  and the  Company  converted  a portion  of its
super-voting  Class B Common  Stock of XM  Radio to Class A Common  Stock.  As a
result,  the Company ceased to control XM Radio, and, effective January 1, 2001,
accounted for its  investment  in XM Radio  pursuant to the equity  method.  The
carrying  value of the Company's  investment in XM Radio  pursuant to the equity
method of  accounting  was $229.0  million (or $15.52 per share) as of March 31,
2001.  As of May 9, 2001,  the market  price of XM Radio common stock was $11.40
per share, $4.12 per share less than the Company's  carrying value.  Pursuant to
the equity method of accounting,  the Company has assessed whether an other than
temporary decline in value of the Company's  investment in XM Radio has occurred
and  whether  a  loss  should  be  recognized.   Considering  market  and  other
appropriate  factors,  the Company does not believe that an other than temporary
decline in the value of its investment in XM Radio has occurred;  however, these
factors could change and cause the Company to recognize a loss in the future.


Sale of Transportation Business

In  November  2000,  Motient  sold its  retail  transportation  assets to Aether
Systems,  Inc.  The purchase  price for these  assets was $45 million,  plus the
then-current  book value of the inventory  for the business.  All of this amount
was paid at closing,  except for $10 million  which was  deposited  in an escrow
account and will be released to Motient upon  satisfaction  of certain  criteria
with respect to  MobileMAX2(TM),  and $3.7 million which will be paid to Motient
upon collection of certain accounts receivable. In addition, the Company has the
opportunity  to  receive up to an  additional  $22.5  million  as an  "earn-out"
payment,  subject to the  satisfaction  of  certain  operating  results  for the
business  during 2001.  The contingent  escrowed and earn-out  payments have not
been  recorded  by the  Company  as of March 31,  2001.  These  amounts  will be
recorded as additional sales proceeds when and if received.

Satellite Ventures

In June 2000 the Company formed a new joint venture subsidiary, Mobile Satellite
Ventures  LLC  ("Satellite  Ventures"),  in which it owns 80% of the  membership
interests.  The remaining 20% interest in Satellite Ventures is owned by certain
investors (the "June Investment Agreement").

In  January  2001,  Motient  entered  into  an  agreement,  subject  to  certain
conditions,  to amend in several respects the terms of the June 2000 transaction
involving  Satellite Ventures.  First, the Investors agreed,  subject to certain
conditions  including  approvals by the FCC, to invest an additional $50 million
to become (in the aggregate) the owners of 40% of the  outstanding  interests of
Satellite Ventures. The Investors will also have an option,  exercisable through
June 29, 2002,  for an additional $40 million,  to increase  their  ownership in
Satellite  Ventures to 50.66% (with each individual  Investor's stake being less
than 20%). Second, upon closing of the transaction, TMI Communications & Company
Limited  Partnership  ("TMI"),  the Canadian satellite  services provider,  will
contribute its satellite  communications  business assets to Satellite Ventures.
TMI will  become the owner of  approximately  27% of the  outstanding  equity of
Satellite Ventures and will also receive a cash payment of $7.5 million, as well
as a $11.5 million 5-year note.

Upon closing of these  transactions,  which is not  scheduled to occur until FCC
approval is received,  Motient  will sell its  remaining  satellite  business to
Satellite Ventures,  in exchange for a cash payment of $45 million and a 5-year,
$15 million note. Upon closing,  the Company will own  approximately  33% of the
outstanding  interests  and be  the  largest  single  shareholder  of  Satellite
Ventures.  A portion of Satellite  Ventures' cash payment to TMI at closing will
be funded by the Company's loan of $2.5 million,  in exchange for a note back in
the same amount.

The Investors have certain rights to elect to convert up to $55 million of their
interests  in  Satellite  Ventures  into shares of  Motient's  common stock at a
conversion price which will be set at the time of exercise,  between $12 and $20
per share.

Company  and are  unaudited.  In the  opinion  of  management,  all  adjustments
(consisting  of normal  recurring  adjustments)  necessary to present fairly the
financial position,  results of operations and cash flows at March 31, 2001, and
for all periods presented have been made.

Consolidation

The consolidated  financial  statements  include the accounts of Motient and its
wholly  owned  subsidiaries.  All  significant  inter-company  transactions  and
accounts have been eliminated.

As noted above,  effective January 1, 2001, the Company's investment in XM Radio
is recorded  pursuant to the equity  method.  For the first  quarter of 2001, XM
Radio recorded no revenue,  incurred $42.1 million of operating expenses and had
a net loss attributable to common stockholders of $42.7 million.

Additionally,  although the Company has an 80%  interest in Satellite  Ventures,
the minority investors have certain participative rights which provide for their
participation  in  certain  business  decisions  that may be made in the  normal
course of business;  therefore,  in accordance  with Emerging  Issues Task Force
Issue No 96-16,  the  Company's  investment  in  Satellite  Ventures is recorded
pursuant to the equity method.

Comprehensive Income

SFAS No.  130,  "Reporting  of  Comprehensive  Income"  requires  "comprehensive
income" and the components of "other comprehensive income" to be reported in the
financial  statements and/or notes thereto.  Since the Company does not have any
components of "other  comprehensive  income," reported net income is the same as
"comprehensive income" for the quarters ended March 31, 2001 and 2000.

Segment Disclosures

In accordance  with SFAS No. 131,  "Disclosures  about Segments of an Enterprise
and Related  Information,"  as of January 1, 2001, the Company has one operating
segment:  its Core Wireless Business.  During 2000, as a result of the Company's
consolidation  of the results of XM Radio,  the Company  reported an  additional
segment for XM Radio's  satellite-based digital audio radio service. The Company
provides its Core Wireless  Business to the continental  United States,  Alaska,
Hawaii,  Puerto Rico, the U.S. Virgin Islands,  and certain U.S. coastal waters.
The following  summarizes the Company's Core Wireless  Business revenue by major
market segments:

Loss Per Share

Basic and diluted loss per common share is computed by dividing income available
to  common  stockholders  by  the  weighted-average   number  of  common  shares
outstanding  for the period.  Diluted  earnings per share reflects the potential
dilution that could occur if securities or other contracts to issue common stock
were  exercised  or  converted  into common stock or resulted in the issuance of
common  stock  that then  shared in the  earnings  of the  entity.  Options  and
warrants to purchase shares of common stock were not included in the computation
of loss per share as the effect would be  antidilutive.  As a result,  the basic
and diluted earnings per share amounts are identical.  Net loss  attributable to
common  shareholders for the quarters ended March 31, 2001 and 2000 includes the
deduction  from net loss of the  Company's  share of XM Radio's  8.25%  Series B
convertible redeemable preferred stock dividend. The dividend was paid on May 1,
2001.


New Accounting Pronouncements

In September  1998, the Financial  Accounting  Standards  Board ("FASB")  issued
Statement  No.  133,   "Accounting   for  Derivative   Instruments  and  Hedging
Activities,"  ("SFAS No. 133") which requires the recognition of all derivatives
as either  assets or  liabilities  measured at fair value.  This  statement  was
originally  effective for the year ended  December 31, 2000. In September  1999,
FASB issued Statement No. 137, which deferred the effective date of SFAS No. 133
until fiscal years beginning after September 15, 2000. In June 2000, FASB issued
Statement No. 138,  "Accounting for Certain  Derivative  Instruments and Certain
Hedging  Activities," which amends SFAS No. 133. This Statement limits the scope
to certain  derivatives and hedging  activities.  The effective date of SFAS No.
138 is for fiscal years beginning after September 15, 2000. The adoption of SFAS
No.  138 in the  first  quarter  of 2001 did not have a  material  impact on the
Company's financial position, results of operations and cash flows.


Concentrations of Credit Risk

For the three  months  ended  March  31,  2001,  five  customers  accounted  for
approximately 30% of the Company's service revenue, with one customer accounting
for more than 10%.

Other

The Company paid approximately $4.4 million in both the three-month period ended
March 31, 2001 and 2000, to related parties for capital assets,  service-related
obligations, and payments under pre-existing financing agreements. There were no
payments from related  parties in the  three-month  periods ended March 31, 2001
and  2000.  Total  indebtedness  to  related  parties  at  March  31,  2001  was
approximately  $8.4 million.  Additionally,  the Company  recorded  revenue from
related parties in the amount of $1.8 million related to the Satellite Ventures'
satellite capacity agreement.

2001 consists of the following:

On March 6, 2001, XM Radio completed a follow-on offering of 7.5 million Class A
common stock,  which yielded net proceeds of $72.0 million.  As a result of this
offering,  the Company  recorded a $13.7 million loss in  accordance  with Staff
Accounting Bulletin No. 51, which addresses the accounting for sales of stock by
a subsidiary.  The loss was recorded in the financial  statements as a reduction
to Additional Paid-In Capital.

4.  LIQUIDITY AND FINANCING

Adequate  liquidity and capital are critical to Motient's ability to continue as
a going concern and to fund subscriber acquisition programs necessary to achieve
positive cash flow and profitable operations. The Company expects to continue to
make significant capital outlays to fund interest expense, new product rollouts,
capital  expenditures and working capital before it begins to generate  positive
cash flow from operations. The Company expects these outlays to continue for the
foreseeable future.

The  successful   implementation   of  the  Company's   business  plan  requires
substantial  funds to finance  the  maintenance  and  growth of its  operations,
network and subscriber  base and to expand into new markets.  The Company has an
accumulated  deficit and has historically  incurred losses from operations which
are expected to continue for additional  periods in the future.  There can be no
assurance that its operations  will become  profitable.  Additionally,  with the
overall decline in the  telecommunications  sector of the capital  markets,  the
Company  has not been able to access the public  markets as  anticipated.  These
factors,  along with the  Company's  negative  operating  cash flows have placed
significant  pressures  on  the  Company's  financial  condition  and  liquidity
position.

In order to work towards adequately funding its projected shortfall, the Company
has executed the following transactions and initiatives in 2001:

o    In  January  and  February   2001,   the  Company  sold,  in  two  separate
     transactions,  2 million shares of its XM Radio Class A Common Stock, at an
     average  price of $16.77 per share,  for total  proceeds of $33.5  million.
     Approximately  $8.5  million  of  the  proceeds  were  used  to  repay  and
     permanently  reduce the Term Facility (as defined  below).  In exchange for
     the Guarantors (as defined below)  agreeing to waive certain debt repayment
     obligations  for the second sale of shares,  the Company and the Guarantors
     have  agreed that the first $16.5  million of  proceeds  received  from the
     earlier of (i) the closing of the Satellite  Ventures  transaction and (ii)
     any  other  reduction  event to occur in the year  2002 will be used to pay
     down the bank financing.

o    On April 3, 2001, Motient received $25 million from Rare Medium Group, Inc.
     ("Rare  Medium"),  and issued Rare Medium a note payable for such amount at
     12.5%  annual  interest  with  a  maturity  date  of  September  30,  2001.
     Additionally,  the Company  has the ability to receive up to an  additional
     $25  million of  funding on  comparable  terms;  the amount of such  second
     tranche will be based on the market price of XM Radio stock.  The notes are
     collateralized  by up to 5 million of the  Company's XM Radio  shares,  and
     Rare Medium has the option to  exchange  the notes for a number of XM Radio
     shares  equivalent to the  principal of the note plus any accrued  interest
     thereon. Of the first $25 million received by the Company, the Company used
     $6.1 million to repay and permanently  reduce its Term Facility,  and $14.4
     million is subject to availability upon the approval of the Guarantors.

     As of April 30, 2001, the Company held approximately 14.7 million shares of
     XM Radio  stock;  however,  approximately  13.7  million of such shares are
     pledged to and held by Rare Medium or the Company's banks and guarantors to
     secure the Company's  obligations  under its bank  financings  and the note
     with Rare Medium. There is no guarantee that the banks and Guarantors would
     agree to release any portion of their share of this  security to permit the
     Company to liquidate its XM Radio shares, or that such approval would be on
     terms favorable to the Company.  Further, the Company's ability to sell its
     shares of XM Radio stock in the public markets is generally  limited to the
     quarterly volume restrictions under Rule 144 of the Securities Act.

o    In April 2001 the Company undertook certain capital and expense reductions,
     principally  in the  areas of  employee  hiring,  advertising  and  capital
     spending.  The Company  believes that these  reductions may result in up to
     approximately  $15  million  of  savings in 2001,  while not  reducing  its
     ability to sell its products or lower its service levels.

o    Additionally,  on May 14,  2001,  the Company  signed a  definitive  merger
     agreement with Rare Medium Group, Inc. See Note 7 - Subsequent  Events. The
     Company believes that the merger, if consummated, would provide the Company
     with  additional  liquidity  and the ability to fund the combined  business
     into 2002.

     The merger  agreement  provides that if necessary  for  liquidity  purposes
     prior to consummation of the merger, and subject to certain conditions, the
     Company may either draw upon the second $25 million  tranche under the Rare
     Medium  bridge loan  agreement  announced  in April  2001,  or sell up to 2
     million additional XM Radio shares, with 50% of such proceeds to be used to
     repay the Term Facility. Upon closing of the transaction,  the bridge loans
     with Rare Medium would be  cancelled  and any shares of XM Radio stock used
     to secure such loans  would be released by Rare Medium and  returned to the
     guarantor collateral pool.

The Company is also a party to the following debt facilities:


Bank Financing

The Company is a party to two bank  facilities (the "Bank  Financing"):  (i) the
Revolving  Credit  Facility,  a  $77.25  million  unsecured  five-year  reducing
revolving  credit facility  maturing  September 30, 2003, and (ii) the Term Loan
Facility, a $31.5 million  (subsequently  reduced to $25.375 million as a result
of the Rare Medium loan, discussed above) five-year,  term loan facility with up
to three additional  one-year  extensions subject to the lenders' approval.  The
Bank  Financing  is  severally  guaranteed  by Hughes  Electronics  Corporation,
Singapore   Telecommunications   Ltd.   and   Baron   Capital   Partners,   L.P.
(collectively,  the  "Guarantors").  As of  April  30,  2001,  the  Company  had
outstanding  borrowings of $25.375 million under the Term Loan Facility at 6.2%,
and $77.25 million under the Revolving Credit Facility at 5.9% to 6.4%. As noted
above,  proceeds,  if any,  from the  Aether $10  million  escrow and the Aether
earn-out will also be used to repay and permanently  reduce the Revolving Credit
Facility,  and  approximately  $30.75  million  from the  exercise of the second
tranche of the Satellite Ventures  transaction,  if successful,  will be used to
repay and permanently  reduce the Revolving  Credit  Facility.  If, at any time,
either of, but not both, the Revolving Credit Facility or the Term Loan Facility
are fully  repaid,  any  excess  required  repayments  will be used to repay and
permanently reduce any remaining Bank Financing.

The Guarantees

In  connection  with  the  Bank  Financing,  the  Guarantors  extended  separate
guarantees of the  obligations  of Motient  Holdings Inc. and the Company to the
banks, which on a several basis aggregate to $108.75 million. In April 2001, the
Guarantors  agreed to release  certain of the shares of XM Radio stock  securing
the Company's  obligations  to the banks and Guarantors to be used as collateral
for the Rare Medium Loan. In exchange for this agreement,  the exercise price of
the Guarantee Warrants, issued as part of the original bank financing agreement,
were  repriced from $6.25 per share to $1.31 per share,  and Singapore  Telecom,
which at that time held no Guarantee Warrants,  was issued 300,000 new warrants.
The total value of this  repricing and issuance was  approximately  $2.3 million
and  will be  recorded  in the  second  quarter  of 2001 as an  increase  to the
unamortized guarantee warrants.

In connection with the Bank Financing, the Company entered into an interest rate
swap agreement, with an implied annual rate of 6.51%. The swap agreement reduced
the impact of interest  rate  increases on the Term Loan  Facility.  The Company
paid a fee of approximately $17.9 million for the swap agreement. Under the swap
agreement,  an  amount  equal  to  LIBOR  plus 50  basis  points,  was paid on a
quarterly basis directly to the respective banks on behalf of the Company,  on a
notional amount of $100 million until the termination date of March 31, 2001.

$335 Million Unit Offering

On March 30,  1998,  Motient  Holdings  Inc.  issued $335  million of Units (the
"Units") consisting of 12 1/4 % Senior Notes due 2008 (the "Senior Notes"),  and
one warrant to purchase 3.75749 shares of Common Stock, subsequently adjusted to
3.83 shares of Common Stock, of the Company for each $1,000  principal amount of
Senior  Notes  (the  "Warrants")  at an  exercise  price of  $12.51  per  share,
subsequently  adjusted  to $12.28 per share.  The  Warrants  were valued at $8.5
million and are reflected in the balance sheet as a debt discount. In connection
with the Senior Notes,  Motient  Holdings Inc.  purchased  approximately  $112.3
million of restricted  investments  that were  restricted for the payment of the
first six  interest  payments on the Senior  Notes.  Interest  payments  are due
semi-annually,  in arrears,  beginning  October 1, 1998.  The final payment from
these restricted investments was made on April 2, 2001.

Other Financing

Motorola  has entered  into an  agreement  with the Company to provide up to $15
million  of vendor  financing,  to finance  up to 75% of the  purchase  price of
additional  network  base  stations.  As of March 31,  2001,  $7.4  million  was
outstanding  under this facility at interest  rates ranging from 13.0% to 13.8%,
and $2.2 million was available for borrowing.  The Company has also arranged the
financing  of certain  trade  payables,  and as of March 31,  2001,  $832,000 of
deferred trade payables were outstanding at rates ranging from 5.9% to 7.2%.

Summary of Liquidity and Financing Sources for Core Wireless Business

The Company's  current  operating  assumptions and projections  reflect its best
estimate  of  subscriber  and revenue  growth and  operating  expenses.  Motient
anticipates that capital  expenditures,  operating  losses,  working capital and
debt  service  requirements  through  2001 can be met by (i) cash on hand,  (ii)
proceeds from the Rare Medium loan,  (iii) its vendor  financing,  (iv) proceeds
realized through the sale of inventory  relating to eLink and BlackBerry TM, (v)
reduction of operating  expenditures,  (vi) additional debt or equity  financing
transactions,  (vii) its  investment in XM Radio,  including  approximately  4.7
million shares to be available for liquidity  and/or debt reduction after giving
effect to the Rare Medium  merger,  and (viii) any cash held by Rare Medium that
would be  available  to the  Company if the Rare Medium  merger is  consummated.
Additionally, the Company has the potential to receive additional funds from the
Aether transaction as well as the Satellite Ventures transaction.  The Company's
financial results could deteriorate,  and its ability to meet its projections is
subject to numerous  uncertainties.  There can be no assurance  that the current
projections  will be achieved.  If  Motient's  cash  requirements  are more than
projected,  it  will  require  additional  financing  in  amounts  which  may be
material.  The type, timing and terms of financing that the Company selects will
be dependent upon the Company's cash needs,  the availability of other financing
sources and the  prevailing  conditions  in the financial  markets.  The Company
cannot  guarantee  that  additional  financing  sources will be available at any
given time or  available  on  favorable  terms.  If the  Company  cannot  secure
additional  financing  as  required,  it may not be able to  continue as a going
concern.


5. COMMITMENTS AND CONTINGENCIES

At March 31, 2001, the Company had remaining contractual commitments to purchase
eLink and other  subscriber  equipment  inventory  in the amount of $9.6 million
during 2001.  Additionally,  the Company has entered  into  product  development
agreements for the purchase of engineering  services and for licenses to be used
in future applications of its eLink product. Should the engineering effort prove
successful,   the  Company  has  committed  to  purchase  additional  subscriber
inventory.  These  commitments,   including  the  inventory  commitment,   total
approximately  $3.6  million  and will be paid during  2001.  Should the Company
decide to cancel these agreements,  it would incur cancellation penalties of any
remaining  unpaid license and  non-recurring  engineering  fees, the cost of any
non-refundable  components purchased on behalf of Motient, plus fifty-percent of
any remaining  inventory  commitment.  As of March 30, 2001,  this  cancellation
penalty would have been approximately $3.2 million.

The aggregate  fixed and  determinable  portion of all commitments for inventory
purchases and other fixed contracts,  related to the core wireless business,  is
$15.4 million, all of which is due in 2001.

6. LEGAL AND REGULATORY MATTERS

Like other mobile  service  providers in the  telecommunications  industry,  the
Company is subject to substantial domestic, foreign and international regulation
including the need for regulatory  approvals to operate and expand the satellite
network and operate and modify subscriber equipment.

The  ownership  and  operation  of the  mobile  satellite  services  system  and
ground-based  two-way  wireless  data  system  are  subject  to  the  rules  and
regulations of the FCC, which acts under authority granted by the Communications
Act and related federal laws. Among other things,  the FCC allocates portions of
the radio  frequency  spectrum to certain  services  and grants  licenses to and
regulates  individual entities using the spectrum.  Motient operates pursuant to
various licenses granted by the FCC.

In the first  quarter of 2001,  the Company  applied to assign its  existing FCC
licenses,  authorizations  and pending  applications  relating to its  satellite
operations to a new company,  Mobile  Satellite  Ventures  Subsidiary  LLC ("MSV
Sub"),  that will be a wholly owned  subsidiary of Satellite  Ventures.  In this
application,  the  Company  also  sought FCC  authority  to launch and operate a
next-generation  mobile satellite  system,  which will include the deployment of
satellites and terrestrial base stations operating in the same frequencies as an
integrated  network.  This  application has been opposed by a number of parties,
some of which argue that (i) the combination of our satellite business with that
of TMI will  decrease  competition;  (ii) our proposed use of  terrestrial  base
stations will cause unacceptable  interference to other L-band  satellites;  and
(iii) the FCC should reallocate spectrum in the L-band to terrestrial use. There

7.  SUBSEQUENT EVENTS

On May 14, 2001,  the Company  signed a definitive  merger  agreement  with Rare
Medium  through  which the Company will  acquire  100% of the  ownership of Rare
Medium,  using a combination of newly issued convertible  preferred stock of the
Company,  and 9 million  shares  of XM Radio  Class A common  stock  held by the
Company.  In the transaction,  each share of Rare Medium's existing common stock
will be exchanged  for  one-tenth of a share of a new  convertible  stock with a
liquidation  preference of $20.00 per share. Each share of convertible preferred
stock will,  in turn,  automatically  convert into 6.4 shares of Company  common
stock,  upon the Company's  common stock  trading above $3.125 per share.  It is
expected that  approximately 41 million new shares of Company common stock would
be issued upon such automatic conversion.

As part of the merger transaction,  the Company will deliver 9 million shares of
XM Radio Class A common  stock owned by it,  plus  approximately  $13 million in
cash, to retire all outstanding shares of preferred stock of Rare Medium,  which
are held by affiliates of Apollo  Management L.P. If the sum of the value of the
XM Radio shares plus the cash is less than $115 million,  the Company will issue
a three-year  promissory note to Apollo in the amount of any  deficiency,  which
note will be  secured  by a second  lien on the assets  securing  the  Company's
guaranteed  bank debt.  The  principal  amount of this note will be subject to a
downward  re-adjustment on September 30, 2001, based on the then-current  market
value of XM Radio stock.

The combined  company  will  provide  wireless  email,  internet  and  corporate
intranet  services,  as well as  software  consulting,  web  based  development,
wireless software,  and network integration services.  The merged companies will
operate as Motient Corporation and will be headquartered in Reston, Virginia.

As of April 30,  2001,  Rare Medium had  approximately  $100  million in cash. A
portion of any cash that remained at Rare Medium at the time of closing would be
used as  follows:  (i) to repay and  permanently  reduce the Term  Facility  and
Revolver by $34 million,  (ii) approximately $13 to $14 million to affiliates of
Apollo Management L.P. (Rare Medium's preferred shareholder) to enable Apollo to
replace Baron Capital and Singapore Telecom as Guarantors, and (iii) to fund the
combined business.  Further,  the Guarantors have required as a condition to the
transaction  that the Company sell 1million XM Radio shares to be used as a 100%
reduction in the Bank  Facility by September  30, 2001.  Hughes has the right to
defer the sale of these shares beyond September 30th.

The merger agreement  provides that if necessary for liquidity purposes prior to
consummation of the merger, and subject to certain  conditions,  the Company may
either draw upon the second $25 million  tranche under its bridge loan agreement
with Rare Medium announced in April 2001, or sell up to 2 million  additional XM
Radio shares,  with 50% of such proceeds to be used to repay the Term  Facility.
Upon  closing of the  transaction,  the bridge  loans with Rare Medium  would be
cancelled  and any shares of XM Radio  stock used to secure  such loans would be
released by Rare Medium and returned to the guarantor collateral pool.

Upon  consummation  of the merger,  the  combined  companies  are expected to be
funded  through  2001.  It is expected that the Company will enter 2002 with the
following  additional  potential sources of liquidity:  (i) up to 4.7 million XM
Radio shares, (ii) cash on hand at year-end, (iii) potential to earn up to $22.5
million  as a result of the  purchase  price  earn-up  from the  Aether  Systems
transaction,  all of which would be required to repay debt,  (iv) the  potential
for $45 million from the second  investment  of the Mobile  Satellite  Ventures'
investors,  half of which would be used to repay debt,  and (v) the potential to
sell for cash some  portion of the Rare  Medium  venture  portfolio.  It is also
expected that the level of  guaranteed  debt at year-end 2001 will be reduced to
less than $50 million.  All of the foregoing  potential sources of liquidity are
subject  to the risks and  uncertainties  described  in Note 4 -  Liquidity  and
Financing.

The consummation of the merger is subject to receipt of all necessary regulatory
approvals and consents, including approvals under the Hart-Scott-Rodino
Antitrust Improvements Act, bank approvals and Rare and Motient shareholder
approvals.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

This  Quarterly  Report on Form 10-Q contains and  incorporates  forward-looking
statements  within the meaning of Section 27A of the  Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All
statements  regarding our expected financial position and operating results, our
business strategy and our financing plans are forward-looking statements.  These
statements can sometimes be identified by our use of forward-looking  words such
as "may," "will,"  "anticipate,"  "estimate,"  "expect," "project," or "intend."
These  forward-looking  statements  reflect our plans,  expectations and beliefs
and,  accordingly,  are subject to certain  risks and  uncertainties.  We cannot
guarantee that any of such forward-looking statements will be realized.

Factors  that  may  cause  actual  results  to  differ   materially  from  those
contemplated  by  such  forward-looking   statements  ("Cautionary  Statements")
include,   among  others,  those  described  under  the  caption   "Management's
Discussion  and  Analysis of  Financial  Condition  and Results of  Operations -
Overview," and elsewhere in this quarterly report, including in conjunction with
the  forward-looking  statements  included in this quarterly report.  All of our
subsequent written and oral  forward-looking  statements (or statements that may
be attributed to us) are expressly qualified by the Cautionary  Statements.  You
should carefully review the risk factors described in our other filings with the
Securities and Exchange Commission (the "SEC") from time to time,  including our
registration statement on Form S-3 (File No. 333-42104),  our most recent annual
report on Form 10-K,  and our  quarterly  reports on Form 10-Q to be filed after
this quarterly report, as well as our other reports and filings with the SEC. In
addition,   you  are  urged  to  carefully  review  the  prospectus   (including
supplements) included within the registration  statement (File No. 333-47570) of
XM Satellite Radio Holdings Inc. ("XM Radio"),  and XM Radio's current report on
Form 8-K dated  February 21, 2001 (File No.  0-27441),  each filed with the SEC,
which describe certain risk factors relating to XM Radio's business,  as well as
XM Radio's other reports filed from time to time with the SEC.

Our forward-looking  statements are based on information  available to us today,
and we  will  not  update  these  statements.  Our  actual  results  may  differ
significantly from the results discussed.

General

This section provides  information which we believe is relevant to an assessment
and  understanding  of the  financial  condition  and  consolidated  results  of
operations  of Motient  Corporation  (with its  subsidiaries,  "Motient"  or the
"Company").  The discussion  should be read in conjunction with the consolidated
financial   statements  and  notes  thereto.   Motient  has  four   wholly-owned
subsidiaries  which, for purposes of this annual report,  are referred to as the
core wireless business.  On a consolidated  basis, we refer to these entities as
Motient.

We also  have a  less-than  100%  interest  in  Mobile  Satellite  Ventures  LLC
(Satellite Ventures), and XM Satellite Radio Holdings Inc. (XM Radio), which are
not consolidated with Motient.

Core Wireless Business

We are a  nationwide  provider of two-way,  wireless  mobile data  services  and
mobile Internet  services.  Our customers use our network and  applications  for
email  messaging  and  dispatch  and  voice  communications  services,  enabling
businesses,  mobile workers and consumers to transfer electronic information and
messages and access corporate databases and the Internet.

Over the  last  several  years,  we have  made  substantial  investments  in new
products and services,  including our eLink(sm) wireless email service, which we
believe  will  capitalize  on the rapid  expansion  of Internet  email usage and
wireless data, particularly in the business-to-business environment.

Our eLink service is a two-way  wireless email device and  electronic  organizer
that uses our terrestrial  network.  We provide our eLink brand two-way wireless
email service to customers  accessing email through corporate servers,  Internet
Service Providers  ("ISP"),  Mail Service Provider ("MSP") accounts,  and paging
network  suppliers.  In November  2000, we launched our BlackBerry TM by Motient
solution  specifically  designed  for large  corporate  accounts  operating in a
Microsoft  Exchange  environment.  BlackBerry  TM is a  popular  wireless  email
solution  developed by Research in Motion  ("RIM") and is being  provided on the
Motient network under license from RIM.

We expect that our rollout of eLink and  BlackBerry TM by Motient will require a
significant  investment  of  financial  resources.  We  believe  that the market
opportunity represented by these wireless data offerings is substantial,  and we
have  decided  to focus  the  majority  of our  available  future  resources  on
expanding our wireless data business. As a result of these factors, and in light
of our  previously-announced  transactions  involving Mobile Satellite  Ventures
LLC, we expect that the future  level of  investment  in our voice  business and
satellite-related  product  lines will  decrease as a percentage  of our overall
investment.  While we expect that this shift in resources will ultimately  yield
an  increase  in our  customer  base,  we expect that it will have the effect of
driving  down  average  revenue per unit as the  percentage  of voice  customers
decreases.

Sale of Retail Transportation Business

In an effort to focus our business on providing wireless data services,  we sold
our retail  transportation assets to Aether Systems, Inc. ("Aether") on November
29, 2000.  Aether  purchased the assets  comprising our wireless  communications
business  for  the  transportation  market,  including  the  satellite-only  and
MobileMAX2(TM)  multi-mode mobile messaging business. Aether acquired all of the
assets  used or useful in the retail  transportation  business,  and assumed the
related  liabilities.  Aether  also  purchased  the  existing  inventory  in the
business, and was granted a perpetual license to use and modify any intellectual
property owned by or licensed to us in connection with the retail transportation
business.  See  "Liquidity and Capital  Resources"  for further  details of this
transaction.

XM Radio

As of December 31, 2000, we had an equity  interest of  approximately  33.1% (or
21.3% on a fully  diluted  basis)  in XM  Satellite  Radio  Holdings  Inc.  ("XM
Radio"),  a public company;  and, as of December 31, 2000 we controlled XM Radio
through our Board of Director  membership and common stock voting  rights.  As a
result,  all of XM Radio's results for the calendar year 2000 have been included
in our consolidated  financial statements.  In January 2001, pursuant to Federal
Communication  Commission  ("FCC")  approval  authorizing  Motient to relinquish
control of XM Radio,  the number of  directors  that we  appointed to XM Radio's
Board of Directors was reduced to less than 50% of XM Radio's directors,  and we
converted  a portion  of our  super-voting  Class B Common  Stock of XM Radio to
Class A Common  Stock.  As a result,  we ceased to control XM Radio,  and, as of
January 1, 2001, we have  accounted for our  investment in XM Radio  pursuant to
the  equity  method.  As of  March  31,  2001,  we had  an  equity  interest  of
approximately 25.3% (15% on a fully diluted basis) in XM Radio.

Satellite Ventures

On June 29, 2000, we formed a new joint venture subsidiary,  Satellite Ventures,
in which we own 80% of the membership interests.  The remaining 20% interests in
Satellite Ventures are owned by three investors  controlled by Columbia Capital,
Spectrum  Equity  Investors LP, and Telcom Ventures  L.L.C.  (collectively,  the
"Investors").  Satellite  Ventures is using our  existing  satellite  network to
conduct  research  and  development  activities  and  exploring  the  technical,
strategic,  and market  potential of new wireless voice and data  communications
services.

In January 2001, we entered into an agreement, subject to certain conditions, to
amend in  several  respects  the  terms of our June 2000  transaction  involving
Satellite Ventures.  First, the Investors agreed, subject to certain conditions,
to invest an additional  $50 million to become (in the  aggregate) the owners of
40% of the outstanding interests of Satellite Ventures.  The Investors will also
have an  option,  exercisable  through  June 29,  2002,  for an  additional  $40
million,  to increase their ownership in Satellite Ventures to 50.66% (with each
individual  Investor's stake being less than 20%).  Second,  upon closing of the
transaction,  TMI  Communications  & Company Limited  Partnership  ("TMI"),  the
Canadian   satellite   services   provider,   will   contribute   its  satellite
communications  business assets to Satellite Ventures,  along with our satellite
business  assets.  TMI  will  become  the  owner  of  approximately  27%  of the
outstanding equity of Satellite  Ventures.  Upon closing of these  transactions,
which is not scheduled to occur until FCC approval is received, we will sell our
remaining satellite assets to Satellite Ventures, and will own approximately 33%
of the outstanding  interests and be the largest single shareholder of Satellite
Ventures.

Our  significant   acquisitions  in  recent  years,   the  sale  of  the  retail
transportation assets to Aether Systems in 2000, and the impact of consolidating
the  results  of XM Radio for 2000,  make  period  to period  comparison  of our
financial results less meaningful, and therefore, you should not rely on them as
an indication of future operating performance.

Overview

We have incurred  significant  operating  losses and negative cash flows in each
year since we started operations,  due primarily to start-up costs, the costs of
developing  and building the  networks and the cost of  developing,  selling and
providing  our products and  services.  We are, and will  continue to be, highly
leveraged (see "Liquidity and Capital Resources" below).

Our  future  operating  results  could be  adversely  affected  by a  number  of
uncertainties and factors, including:

o    our ability to secure  additional  financing  necessary to fund anticipated
     capital expenditures,  operating losses and debt service requirements,  and
     our dependence on selling XM Radio shares and certain limitations thereon,
o    the timely  roll-out of certain key customer  initiatives and the launch of
     new products or the entry into new market segments, which may require us to
     continue to incur significant operating losses,
o    our ability to realize the earn-out and escrow deferred  payments under the
     Aether transaction,
o    our ability to fully recover the value of our inventory in a timely manner,
o    our  ability  to gain  market  acceptance  of new  products  and  services,
     including our new product offerings,  eLink,  BlackBerryTM by Motient,  and
     eLink Fortified with Yahoo!
o    our  ability  to  respond  and react to  changes  in our  business  and the
     industry because we have substantial indebtedness,
o    our  ability  to modify  our  organization,  strategy  and  product  mix to
     maximize the market  opportunities as the market changes,  o our ability to
     manage growth effectively,
o    competition  from existing  companies that provide  services using existing
     communications   technologies  and  the  possibility  of  competition  from
     companies using new technology in the future,
o    our ability to  maintain,  on  commercially  reasonable  terms,  or at all,
     certain technologies licensed from third parties,
o    the loss of one or more of our key customers,
o    our ability to attract and retain key personnel,
o    the timely  availability of an adequate  supply of subscriber  equipment at
     competitive  price points,  o our  dependence  on third party  distribution
     relationships  to provide access to potential  customers,  o our ability to
     expand our  networks  on a timely  basis and at a  commercially  reasonable
     cost, or at all, as additional future demand increases,
o    our ability to maintain our listing on the Nasdaq  National  Market and the
     impact that would have on an investor's ability to sell shares,
o    regulation by the FCC, and
o    technical  anomalies that may occur within the network,  including  product
     development,  which could impact, among other things, customer performance,
     satisfaction  and  revenue  under  contractual  arrangements  with  certain
     customers, or the operation of the satellite network and the cost, scope or
     availability of in-orbit insurance.

We have a  significant  investment  in XM Radio which may be affected by certain
risks which, in turn, may impact the market price of our stock.  For an expanded
discussion of XM Radio's risk factors,  please refer to XM Radio's most recently
filed prospectus (including  supplements thereto), its most recent Annual Report
on Form 10-K, and its other reports filed from time to time with the SEC.

XM Radio is a development  stage  company with no revenues,  and its business is
subject  to a number  of  significant  risks  and  uncertainties  including  the
following:

o    the ability to obtain additional  financing necessary to complete the build
     out of its system and maintain  operations  until such time as it can reach
     cash flow positive,
o    premature failure of XM Radio's satellites that may not be fully covered by
     insurance,  or natural  disasters that could damage the service  network or
     ground facilities for which there are no backups,
o    the failure by  satellite  and launch  contractors  to deliver  functioning
     systems  in a timely  manner,  for  which XM  Radio  may not have  adequate
     remedies,
o    the ability of XM Radio to successfully integrate complex technologies into
     a technologically  feasible  configuration,  as well as rapid technological
     changes that could make XM Radio's service obsolete,
o    the timely  availability of XM Radio's subscriber  equipment at competitive
     prices,
o    competition from traditional and emerging audio entertainment  providers or
     the potential for customers to steal their signals,  which could  adversely
     affect revenues,
o    the ability of XM Radio to gain market acceptance of its service,
o    the ability of XM Radio to achieve profitability given certain distribution
     agreement obligations and joint development funding requirements,
o    the ability to  maintain,  on  commercially  reasonable  terms,  or at all,
     certain technologies licensed from third parties,
o    the  ability to respond  and react to  changes  in their  business  and the
     industry because of their substantial debt,
o    the ability to attract and retain key employees,
o    regulation by the FCC, and
o    the  potential  impact to its stock price as a result of certain  preferred
     stockholder rights and potential future issuances of common stock.


Three Months Ended March 31, 2001 and 2000

Revenue and Subscriber Statistics

Service revenue, which includes our data, voice, and capacity reseller services,
approximated  $18.0  million for the three months  ended March 31,  2001,  which
constituted  an $800,000,  or 5% increase  over the first  quarter of 2000.  The
increase in service  revenues was attributable to a 50% increase in subscribers,
partially offset by a significant reduction in average revenue per unit ("ARPU")
in most market segments.

Summary of Quarter over Quarter Revenue

o    The growth in wireless  internet revenue reflects the overall growth in the
     number of units,  offset by ARPU  reductions as a result of a shift towards
     more reseller pricing  contracts.  Our eLink product was introduced in late
     1999 and did not begin to achieve a material  growth  rate until the middle
     of 2000 as certain reseller initiatives were launched.
o    The decrease in revenue from field services  reflects contract renewal rate
     reductions that occurred in the first quarter of 2001.
o    The decrease in revenue from our  transportation  product was primarily the
     result  of the sale of our  transportation  assets  to  Aether  late in the
     fourth  quarter of 2000 and the  resulting  decrease  in ARPU as we shifted
     from retail  rates to our direct  customers,  to  wholesale  rates  through
     Aether. This decrease was partially offset by the increase in the number of
     units under our United Parcel Service contract.
o    The  decrease in telemetry  revenue  reflects the change from a take or pay
     agreement to a usage based agreement with one customer.
o    The  growth in voice and other  revenue  was  primarily  the result of $1.8
     million of revenue earned from our contract to provide  Satellite  Ventures
     with  satellite  capacity as they pursue  their  research  and  development
     program.  This  increase  was  partially  offset by ARPU  decreases  in the
     maritime market.
o    The  increase  in  equipment   revenue  is  a  result  of  an  increase  of
     approximately  $9.0 million in equipment sales for our eLink product lines,
     offset by (i) a $165,000  decrease  in voice  equipment  sales and (ii) the
     loss of $2.9 million of  equipment  sales  associated  with the sale of our
     transportation business.

The results for the quarter ended March 31, 2000,  included expenses incurred by
XM Radio, as we were required to consolidate  their results.  As noted above, as
of January 1, 2001, we were no longer  required to consolidate the results of XM
Radio.

Cost of service and  operations  includes  costs to support  subscribers  and to
operate  the  network.  The  increase  in cost of  service  and  operations  was
primarily attributable to (i) a 12% increase in communication charges associated
with an 13% increase in base stations year over year and (ii) a 28% increase for
site rental costs associated with the build out of the terrestrial  network. The
increases  were  partially  offset  by  approximately   $2.0  million  of  costs
associated with the sale of our transportation assets in late 2000.

The increase in cost of equipment sold for the quarter ended March  31,2001,  as
compared to the same period in 2000,  was a result of our growth in the sales of
our eLink product line, which have a lower revenue per unit as compared to voice
or transportation  equipment,  offset by the loss of equipment sales as a result
of the sale of our transportation business.

Sales  and   advertising   expenses  as  a  percentage  of  total  revenue  were
approximately  41% for the first  quarter of 2001,  compared to 28% for the same
period in 2000.  The  increase in sales and  advertising  expenses  quarter over
quarter  was  primarily  attributable  to  (i) a  market  awareness  advertising
campaign  in  the  first  quarter  of  2001  to  heighten  our  presence  in the
marketplace  and to highlight our new product  offerings,  (ii)  advertising and
other costs  associated with our roll out of our eLink fortified with Yahoo!(TM)
product, and (iii) eLink subscriber acquisition costs.

General  and  administrative  expenses  for  the  core  wireless  business  as a
percentage  of total  revenue were  approximately  27% for the first  quarter of
2001,  compared to 25% for the first quarter of 2000. The increase in 2001 costs
over  2000  costs in our  core  wireless  business  general  and  administrative
expenses was primarily  attributable to the vesting of certain  restricted stock
grants in the first quarter of 2001.

Depreciation and amortization for the core wireless  business was  approximately
37% of total  revenue  for the first  quarter of 2001,  compared  to 40% for the
first quarter of 2000. The decrease in depreciation and amortization  expense in
the  first  quarter  of  2001  was  primarily  attributable  to the  sale of our
transportation  assets  in the  fourth  quarter  of 2000  and  their  associated
depreciation.

Interest and other income was $142,000 for the quarter  ended March 31, 2001, as
compared to $5.2  million (of which $4.1 million was earned by XM Radio) for the
quarter  ended  March 31,  2000.  Excluding  interest  earned  by XM Radio,  the
$900,000  decrease in interest  earned by the core  wireless  business  reflects
reduced  interest  earned on our escrow  established  for the Senior  Notes as a
result of a lower escrow balance.

We  incurred  $15.4  million of interest  expense in the first  quarter of 2001,
compared  to $15.0  million  during  the first  quarter  of 2000.  The  $400,000
increase  for the  quarter  was a result of (i) a decrease  in  amortization  of
warrants  and (ii)  prepaid  interest  and debt  offering  costs due to the debt
discount  costs that were  written off in 2000 and 2001 when we  extinguished  a
portion of debt under the bank facilities. These decreases were partially offset
by increased vendor debt and capital lease obligations.

Net capital  expenditures  for the quarter ended March 31, 2001 for property and
equipment  were $3.3 million  compared to $4.9 million  (excluding  $4.9 million
incurred by XM Radio) for the comparable period in 2000.  Expenditures consisted
primarily  of assets  necessary  to  continue  the build out of our  terrestrial
network.

Net capital  expenditures  during the first  quarter of 2000 for property  under
construction  represented  those costs  associated  with the build out of the XM
Radio network.

Liquidity and Capital Resources

Adequate  liquidity  and  capital  are  critical to our ability to continue as a
going concern and to fund subscriber  acquisition  programs necessary to achieve
positive  cash flow and  profitable  operations.  We expect to  continue to make
significant  capital  outlays to fund interest  expense,  new product  rollouts,
capital  expenditures  and working capital before we begin to generate  positive
cash  flow  from  operations.  We  expect  these  outlays  to  continue  for the
foreseeable future.

Summary of Liquidity and Financing Sources for Core Wireless Business

Our current operating  assumptions and projections  reflect our best estimate of
subscriber and revenue growth and operating expenses. We anticipate that capital
expenditures,  operating losses,  working capital and debt service  requirements
through 2001 can be met by (i) cash on hand,  (ii)  proceeds  from the Rare loan
(see below) (iii) borrowings available under our vendor financing, (iv) proceeds
realized through the sale of inventory  relating to eLink and BlackBerry TM, (v)
reduction of operating  expenditures,  (vi) additional debt or equity  financing
transactions,  (vii) our  investment in XM Radio,  including  approximately  4.7
million shares to be available for liquidity  and/or debt reduction after giving
effect to the Rare  Medium  merger,  and (viii)  cash held by Rare that would be
available to us if the Rare merger is consummated (see below). Additionally,  we
have the potential to receive  additional  funds from the Aether  transaction as
well  as  the  Satellite  Ventures  transaction.  Our  financial  results  could
deteriorate,  and our  ability to meet our  projections  is subject to  numerous
uncertainties,  and there can be no assurance that the current  projections will
be achieved.  If our cash requirements are more than projected,  we will require
additional  financing  in amounts  which may be material.  The type,  timing and
terms of financing that the we select will be dependent upon our cash needs, the
availability  of other  financing  sources and the prevailing  conditions in the
financial markets. We cannot guarantee that additional financing sources will be
available at any given time or available on favorable terms. If we cannot secure
additional  financing  as may be  required,  we may not be able to continue as a
going concern.

The successful implementation of our business plan requires substantial funds to
finance the  maintenance  and growth of our  operations,  network and subscriber
base and to expand into new  markets.  We have an  accumulated  deficit and have
historically  incurred losses from operations which are expected to continue for
additional periods in the future.  There can be no assurance that our operations
will  become  profitable.   Additionally,   with  the  overall  decline  in  the
telecommunications  sector  of the  capital  markets,  we have not been  able to
access the public markets as anticipated. These factors, along with our negative
operating  cash  flows,  have  placed  significant  pressures  on our  financial
condition and liquidity position.

In order to work towards  adequately  funding our projected  shortfall,  we have
executed the following transactions and initiatives in 2001:

o    In January and February  2001,  we sold,  in two separate  transactions,  2
     million shares of our XM Radio Class A Common Stock, at an average price of
     $16.77 per share, for total proceeds of $33.5 million.  Approximately  $8.5
     million of the proceeds were used to repay and permanently  reduce our bank
     financing.  In exchange for the  guarantors  agreeing to waive certain debt
     repayment  obligations for the second sale of shares, we and the guarantors
     have  agreed that the first $16.5  million of  proceeds  received  from the
     earlier of (i) the closing of the Satellite  Ventures  transaction and (ii)
     any  other  reduction  event to occur in the year  2002 will be used to pay
     down the bank financing.

o    On April 3, 2001,  we received  $25 million  from Rare Medium  Group,  Inc.
     ("Rare  Medium"),  and issued  Rare Medium a note  payable at 12.5%  annual
     interest  with a maturity  date,  subject to certain  mutually-agreed  upon
     extensions,  of September 30, 2001. Additionally,  we have the potential to
     receive up to an additional $25 million of funding on comparable terms; the
     amount of such second tranche will be based on the market price of XM Radio
     stock.  The notes  are  collateralized  by up to 5 million  of our XM Radio
     shares,  and Rare has the option to  exchange  the notes for a number of XM
     Radio  shares  equivalent  to the  principal  of the note plus any  accrued
     interest thereon.  Of the first $25 million that we received,  we used $6.1
     million  to repay and  permanently  reduce  our bank  financing,  and $14.4
     million is subject to availability upon the approval of the guarantors.

     As of April 30, 2001, we held approximately 14.7 million shares of XM Radio
     stock;  however,  approximately  13.7 million of such shares are pledged to
     and  held  by Rare  Medium  or our  banks  and  guarantors  to  secure  our
     obligations under our bank financings and the note with Rare Medium.  There
     is no guarantee  that the banks and  guarantors  would agree to release any
     portion of their share of this  security to permit us to  liquidate  our XM
     Radio  shares,  or that such  approval  would be on terms  favorable to us.
     Further,  our  ability to sell our  shares of XM Radio  stock in the public
     markets is generally  limited to the quarterly  volume  restrictions  under
     Rule 144 of the Securities Act.

     The carrying  value of our  investment  in XM Radio  pursuant to the equity
     method of accounting  was $229.0  million (or $15.52 per share) as of March
     31, 2001. As of May 9, 2001,  the market price of XM Radio common stock was
     $11.40 per share, $4.12 per share less than our carrying value. Taking into
     consideration  market and other appropriate factors, we do not believe that
     other than a temporary  decline in the value of our  investment in XM Radio
     has occurred and,  accordingly,  we have not recognized a loss; however, we
     cannot guarantee that a loss will not be recognized in the future.

o    In  April  2001  we  undertook  certain  capital  and  expense  reductions,
     principally  in the  areas of  employee  hiring,  advertising  and  capital
     spending.   We  believe  that  these   reductions   may  result  in  up  to
     approximately  $15  million  of  savings in 2001,  while not  reducing  our
     ability to sell our products or lower our service levels.

o    Additionally, on May 14, 2001, we signed a definitive merger agreement with
     Rare Medium  through  which we will acquire  100% of the  ownership of Rare
     Medium, using a combination of newly issued convertible preferred stock and
     9 million  shares of XM Radio  Class A common  stock  that we hold.  In the
     transaction,  each share of Rare  Medium's  existing  common  stock will be
     exchanged  for  one-tenth  of a share of a new  series  of our  convertible
     preferred  stock with a liquidation  preference  of $20.00 per share.  Each
     share of convertible  preferred stock will, in turn,  automatically convert
     into 6.4 shares of our common  stock,  upon our stock  trading above $3.125
     per share. We expect that approximately 41 million new shares of our common
     stock would be issued upon such automatic conversion.

     As part of the  merger  transaction,  the  Company  will  deliver 9 million
     shares of XM Radio Class A common stock owned by it, plus approximately $13
     million in cash,  to retire all  outstanding  shares of preferred  stock of
     Rare Medium,  which are held by affiliates of Apollo Management L.P. If the
     sum of the  value of the XM Radio  shares  plus the cash is less  than $115
     million,  the Company will issue a three-year  promissory note to Apollo in
     the amount of any  deficiency,  which note will be secured by a second lien
     on the assets  securing the Company's  guaranteed  bank debt. The principal
     amount  of this  note  will  be  subject  to a  downward  re-adjustment  on
     September  30,  2001,  based on the  then-current  market value of XM Radio
     stock.

     The combined  company will provide  wireless email,  internet and corporate
     intranet services,  as well as software consulting,  web based development,
     wireless software,  and network integration services.  The merged companies
     will operate as Motient  Corporation and will be  headquartered  in Reston,
     Virginia.

     As of April 30, 2001, Rare Medium had approximately $100 million in cash. A
     portion  of any cash that  remained  at Rare  Medium at the time of closing
     would be used as  follows:  (i) to repay and  permanently  reduce  the Term
     Facility and Revolver by $34 million, (ii) approximately $13 to $14 million
     to  affiliates  of  Apollo   Management   L.P.  (Rare  Medium's   preferred
     shareholder)  to enable  Apollo to  replace  Baron  Capital  and  Singapore
     Telecom as Guarantors,  and (iii) to fund the combined  business.  Further,
     the guarantors have required as a condition to the transaction that we sell
     1million  XM  Radio  shares  to be used  as a 100%  reduction  in the  Bank
     Facility by September  30, 2001.  Hughes has the right to defer the sale of
     these shares beyond September 30th.

     The merger  agreement  provides that if necessary  for  liquidity  purposes
     prior to consummation of the merger, and subject to certain conditions,  we
     may either draw upon the second $25 million  tranche  under our bridge loan
     agreement with Rare Medium announced in April 2001, or sell up to 2 million
     additional XM Radio  shares,  with 50% of such proceeds to be used to repay
     the bank financing  facility.  Upon closing of the transaction,  the bridge
     loans with Rare Medium would be cancelled  and any shares of XM Radio stock
     used to secure such loans would be released by Rare Medium and  returned to
     the guarantor collateral pool.

     Upon consummation of the merger,  the combined companies are expected to be
     funded  through  2001. It is expected that the Company will enter 2002 with
     the following  additional  potential  sources of  liquidity:  (i) up to 4.7
     million XM Radio shares, (ii) cash on hand at year-end,  (iii) potential to
     earn up to $22.5 million as a result of the purchase price earn-up from the
     Aether Systems  transaction,  all of which would be required to repay debt,
     (iv) the potential for $45 million from the second investment of the Mobile
     Satellite  Ventures'  investors,  half of which is  required  to be used to
     repay debt,  and (v) the potential to sell for cash and some portion of the
     Rare  Medium  venture  portfolio.  It is also  expected  that the  level of
     guaranteed  debt at year-end 2001 will be reduced to less than $50 million.
     The  foregoing  statements  regarding  potential  sources of liquidity  are
     subject to the risks and  uncertainties  described  above under "Summary of
     Liquidity and Financing Sources for Core Wireless Business."

     The  consummation  of the merger is  subject  to  receipt of all  necessary
     regulatory   approvals  and  consents,   including   approvals   under  the
     Hart-Scott-Rodino  Antitrust  Improvements  Act,  bank  approvals  and Rare
     Medium and Motient shareholder approvals.

Our other current financing arrangements are summarized below:

o    A $108.75  million  bank  financing  facility,  consisting  of (i) a $77.25
     million unsecured  five-year  reducing  revolving credit facility,  none of
     which was available  for  borrowing as of March 31, 2001,  and (ii) a $31.5
     million five-year term loan facility,  with up to three additional one-year
     extensions  subject  to the  lenders'  approval,  which is  secured  by our
     assets,  principally our  stockholdings  in XM Radio. The bank financing is
     severally   guaranteed  by  Hughes   Electronics   Corporation,   Singapore
     Telecommunications  Ltd., and Baron Capital Partners,  L.P. Both facilities
     bear  interest,  generally,  at 100 basis  points  above  London  Interbank
     Offered Rate C LIBOR.  Certain proceeds that we may receive are required to
     be used to repay and reduce the bank financing,  unless otherwise waived by
     the lenders and the  guarantors.  As of March 31, 2001, we had  outstanding
     borrowings of $31.5  million under the term loan facility at  approximately
     6.2%,  and $77.25  million  under the  revolving  credit  facility at rates
     ranging  from  6.0% to 8.0%.  On April  11,  2001,  as a result of the Rare
     Medium  Loan,  we reduced our term loan  facility by an  additional  $6.125
     million,  and had a balance outstanding on the term loan of $25.375 million
     as of April 30, 2001. Additionally,  in connection with the bank financing,
     we entered into an interest rate swap agreement which reduced the impact of
     interest  rate  increases  on  the  term  loan  facility.  Under  the  swap
     agreement,  which  expired in March 2001,  we  received an amount  equal to
     LIBOR  plus 50 basis  points,  paid  directly  to the banks on a  quarterly
     basis, on a notional  amount of $41 million until the  termination  date of
     March 31, 2001.

     As noted below,  any proceeds we receive from the Aether escrow or earn-out
     will be used to repay and permanently reduce the revolving credit facility.
     Additionally,  the first  $30.75  million of funds from the  closing of the
     second  Satellite  Venture's  transaction,  if successful,  will be used to
     repay and permanently reduce the revolving credit facility.

o    A vendor  financing  commitment  from  Motorola,  Inc., a  stockholder,  to
     provide up to $15 million of vendor  financing  to finance up to 75% of the
     purchase price of additional terrestrial network base stations. Loans under
     this  facility  bear  interest  at a rate  equal to LIBOR plus 7.0% and are
     guaranteed by Motient and each of its wholly-owned subsidiaries.  The terms
     of the facility  require that amounts  borrowed be secured by the equipment
     purchased therewith. As of April 30, 2001, there was $2.2 million available
     for borrowing under this facility.

o    $9.6 million capital lease for network equipment acquired in July 2000. The
     lease has a term of three years and an effective interest rate of 14.718%.

o    $335  million of senior  notes  issued in 1998,  at the time of the Motient
     Communications Acquisition.  The notes bear interest at 12.25% annually and
     are due in 2008. A portion of the net proceeds of the sale of the notes was
     used to finance  pledged  securities  that are  intended to provide for the
     payment of the first six  interest  payments  on these  notes,  the last of
     which was made on April 2, 2001.  Interest payments are due  semi-annually,
     in  arrears,  and began on  October 1,  1998.  The notes  were  issued by a
     subsidiary of Motient, and are fully guaranteed by Motient.

o    We have also arranged the financing of certain  trade  payables,  and as of
     April 30, 2001,  $400,000 of a deferred trade payable was  outstanding at a
     rate of 7.24% and is payable by the end of 2001.


Sale of Retail Transportation Business to Aether Systems

In November 2000, we sold our retail  transportation  assets to Aether  Systems,
Inc. The purchase price for these assets was $45 million,  plus the then-current
book value of the  inventory  for the  business.  All of this amount was paid at
closing,  except for $10 million  which was  deposited in an escrow  account and
will be released to Motient upon  satisfaction of certain  criteria with respect
to  MobileMAX2(TM),  and $3.7 million which was held back and will be paid to us
upon  collection  of  certain  accounts  receivable.  In  addition,  we have the
opportunity  to  receive up to an  additional  $22.5  million  as an  "earn-out"
payment,  subject to the  satisfaction  of  certain  operating  results  for the
business during 2001. Of the proceeds received at closing,  $20 million was used
to  immediately  repay and  permanently  reduce the revolving  credit  facility.
Proceeds,  if any, from the $10 million  escrow and the $22.5  million  earn-out
will be recorded as  additional  purchase  consideration  when received and will
also be used to repay and permanently reduce the revolving credit facility.

Commitments

At March 31, 2001, we had remaining  contractual  commitments  to purchase eLink
and  other  subscriber  equipment  inventory  in the  amount  of  $9.6  million.
Additionally,  we have  entered  into  product  development  agreements  for the
purchase  of  engineering  services  and  for  licenses  to be  used  in  future
applications  of  our  eLink  product.   Should  the  engineering  effort  prove
successful, we have committed to purchase additional subscriber inventory. These
commitments,  including  the  inventory  commitment,  total  approximately  $3.6
million  and  will be paid  during  2001.  Should  we  decide  to  cancel  these
agreements,  we would  incur  cancellation  penalties  of any  remaining  unpaid
license  and  non-recurring  engineering  fees,  the cost of any  non-refundable
components  purchased  on  our  behalf,  plus  fifty-percent  of  any  remaining
inventory commitment. As of March 31, 2001, this cancellation penalty would have
been approximately $3.3 million.

The aggregate  fixed and  determinable  portion of all commitments for inventory
purchases and other fixed contracts,  related to the core wireless business,  is
$15.4 million, all of which is due in 2001.

XM Radio

XM Radio is operated,  managed,  and funded  separately  from our core  wireless
business.  While  we do not  have  any  obligation  or  commitments  to  provide
additional  funding to XM Radio,  and do not expect to  provide  any  additional
funding, we may choose to do so in the future. XM Radio will require significant
additional funding in the future. If XM Radio is not successful in obtaining the
additional  required  financing,  our investment in XM Radio could be negatively
impacted.

Satellite Ventures

As noted above, in June 2000 we formed a new joint venture subsidiary, Satellite
Ventures,  in which we own 80% of the  membership  interests.  The remaining 20%
interest in Satellite Ventures is owned by the Investors.

In January 2001, we entered into an agreement, subject to certain conditions, to
amend in  several  respects  the  terms of our June 2000  transaction  involving
Satellite Ventures.  First, the Investors agreed,  subject to certain conditions
including  approvals by the FCC, to invest an  additional  $50 million to become
(in the aggregate) the owners of 40% of the  outstanding  interests of Satellite
Ventures.  The Investors will also have an option,  exercisable through June 29,
2002,  for an additional $40 million,  to increase their  ownership in Satellite
Ventures to 50.66% (with each individual  Investor's stake being less than 20%).
Second,  upon closing of the transaction,  TMI  Communications & Company Limited
Partnership ("TMI"),  the Canadian satellite services provider,  will contribute
its satellite  communications business assets to Satellite Ventures,  along with
our satellite business assets. TMI will become the owner of approximately 27% of
the  outstanding  equity of  Satellite  Ventures  and will  also  receive a cash
payment of $7.5 million, as well as a $11.5 million 5-year note.

Upon closing of these transactions,  we will sell our remaining satellite assets
to  Satellite  Ventures,  in  exchange  for a cash  payment of $45 million and a
5-year,  $15 million note. Upon closing,  we will own  approximately  33% of the
outstanding  interests  and be  the  largest  single  shareholder  of  Satellite
Ventures.  A portion of Satellite  Ventures' cash payment to TMI at closing will
be funded by our loan of $2.5  million,  in exchange for a note back in the same
amount.

Under the original  transaction,  at any time until June 29, 2002, the Investors
had certain  rights to elect to convert  their  interests in Satellite  Ventures
into shares of our common stock at a  conversion  price which will be set at the
time of  exercise,  between  $12 and $20 per  share,  as  specified  in the June
Investment Agreement. As part of the January 2001 agreement,  this right remains
in place, but is limited to an aggregate of $55 million.

Under the terms of the bank facility  waivers  received by Motient in connection
with the January 2001 agreement,  approximately $30.75 million of all amounts to
be received by Motient from Satellite Ventures in connection with Motient's sale
of its  satellite  business  assets to  Satellite  Ventures,  including  the $45
million  in cash  and  $15  million  note  receivable,  will  be  used to  repay
outstanding  amounts,  and  permanently  reduce  commitments,   under  Motient's
revolving credit facility.

(1)  As noted above, the three-month  period ended March 31, 2000,  includes the
     results  of XM Radio.  As of  January  1,  2001,  results  of XM Radio were
     recorded on an equity basis.

The $8.8  million  decrease in cash used in  operating  activities  for the core
business was primarily  attributable to working capital changes primarily within
accounts payable.

The $38.8  million  increase in cash used in  investing  activities  of the core
business was primarily  attributable  to the sale of 2 million  shares of our XM
Radio stock for net proceeds of approximately $33.5 million, partially offset by
the purchase, in the first quarter of 2000, of certain restricted investments.

The $42.1 million decrease in cash provided by financing  activities in the core
business  was a result of (i) the  reduction  in proceeds  from the  exercise of
stock option and warrants in the amount of $5.2 million in the first  quarter of
2000, as compared to $259,000 in the first quarter of 2001 and (ii) a difference
of $36.5  million  in net bank  financings  from the  first  quarter  of 2000 as
compared to the first quarter of 2001. This change in the use of bank financings
was offset by the sale of XM Radio stock, noted above.

Other

All of our wholly owned  subsidiaries  are subject to financing  agreements that
limit the amount of cash  dividends  and loans that can be  advanced  to Motient
Parent.  At March 31, 2001, all of the  subsidiaries' net assets were restricted
under these agreements. These restrictions will have an impact on our ability to
pay dividends.


Regulation

On  November  30,  1999,  the  FCC  granted  two   applications   to  use  TMI's
Canadian-licensed  system  to  provide  service  in the  United  States to up to
125,000  mobile  terminals.  TMI's  system  operates in the MSS L-band and has a
satellite  footprint that covers the United States.  We appealed the FCC's grant
of  these  applications  to the  United  States  Court of  Appeals  for the D.C.
Circuit,  but the court  upheld the FCC's  grant.  TMI's entry into the domestic
U.S.  marketplace  may increase  TMI's demand for spectrum in the  international
coordination  process  and  otherwise  make it more  difficult  for us to secure
access to 20 MHz of spectrum.  Since the initial grant to use TMI's system,  the
FCC has  granted an  additional  application  to use TMI's  system and may grant
others.  The  FCC is also  currently  considering  applications  to  access  the
Inmarsat  satellite system in the L-band to provide mobile satellite  service in
the United  States,  which may further  adversely  impact  Motient's  ability to
coordinate spectrum access.

On January 16, 2001, we amended our pending  application  with the FCC to launch
and operate a second-generation  mobile satellite system in numerous respects to
seek FCC approval for the transactions  involving Satellite Ventures,  including
the  combination  of  our  satellite  communications  business  with  TMI.  This
application  has been  opposed by a number of parties,  some of which argue that
(i) the  combination  of our  satellite  business with that of TMI will decrease
competition;  (ii) our  proposed use of  terrestrial  base  stations  will cause
unacceptable  interference to other L-band satellites;  and (iii) the FCC should
reallocate spectrum in the L-band to terrestrial use. There is no assurance that
the FCC will grant our application.

Accounting Standards

In September  1998, the Financial  Accounting  Standards  Board ("FASB")  issued
Statement  No.  133,   "Accounting   for  Derivative   Instruments  and  Hedging
Activities,"  ("SFAS No. 133") which requires the recognition of all derivatives
as either  assets or  liabilities  measured at fair value.  This  statement  was
originally  effective for the year ended  December 31, 2000. In September  1999,
FASB issued Statement No. 137, which deferred the effective date of SFAS No. 133
until fiscal years beginning after September 15, 2000. In June 2000, FASB issued
Statement No. 138,  "Accounting for Certain  Derivative  Instruments and Certain
Hedging  Activities," which amends SFAS No. 133. This Statement limits the scope
to certain  derivatives and hedging  activities.  The effective date of SFAS No.
138 is for fiscal years beginning after September 15, 2000. The adoption of SFAS
No.  138 in the  first  quarter  of 2001 did not have a  material  impact on our
financial position, results of operations and cash flows.





Item 3. Quantitative and Qualitative Disclosures about Market Risk

Quantitative and Qualitative Disclosures about Market Risk

We are  exposed to the impact of  interest  rate  changes  related to our credit
facilities.  We manage  interest rate risk through the use of a  combination  of
fixed and  variable  rate  debt.  Currently,  except for the  interest  rate cap
described  below, we do not use derivative  financial  instruments to manage our
interest rate risk.  We have minimal cash flow exposure due to general  interest
rate changes for our fixed rate, long-term debt obligations.  We invest our cash
in  short-term  commercial  paper,  investment-grade  corporate  and  government
obligations and money market funds.

Under our Term Loan and Revolving Credit Facility, interest is paid generally at
100 basis points above LIBOR.  The  exposure to interest  rate  fluctuations  is
limited  because the interest rate paid on a monthly basis is variable and based
on current market conditions.  Our Senior Notes bear interest at a fixed rate of
12 1/4%.  We run the risk  that  market  rates  will  decline  and the  required
payments will exceed those based on current market rates.
