             AMERICAN MOBILE SATELLITE CORPORATION AND SUBSIDIARIES
                          (A Development Stage Company)
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

                               September 30, 1996
                                   (Unaudited)


1.  Organization and Business

     American Mobile  Satellite  Corporation was incorporated on May 3, 1988, by
eight of the  initial  applicants  for the mobile  satellite  services  license,
following a determination by the Federal Communications  Commission ("FCC") that
the public interest would best be served by granting the license to a consortium
of all willing,  qualified  applicants.  The FCC has authorized  American Mobile
Satellite  Corporation  to  construct,  launch,  and operate a mobile  satellite
services  system (the "SKYCELL  System") to provide a full range of mobile voice
and data  services  via  satellite  to land,  air and  sea-based  customers in a
service area consisting of the continental United States, Alaska, Hawaii, Puerto
Rico, the U.S. Virgin Islands,  U.S.  coastal waters,  international  waters and
airspace and any foreign territory where the local government has authorized the
provision  of service.  In March 1991,  American  Mobile  Satellite  Corporation
transferred the mobile  satellite  services  license ("MSS license") to a wholly
owned subsidiary,  AMSC Subsidiary  Corporation  ("AMSC  Subsidiary").  American
Mobile  Satellite  Corporation  has six  other  subsidiaries,  two of which  are
inactive and four whose limited  activities do not require material resources at
this  time.  On April  7,1995,  the  Company  successfully  launched  its  first
satellite ("AMSC-1"), from Cape Canaveral, Florida.

     American  Mobile  Satellite  Corporation  (together  with its  subsidiaries
"AMSC" or the "Company") is devoting its efforts to establishing a new business.
As further  discussed  in  Management's  Discussion  and  Analysis of  Financial
Condition and Results of  Operations,  this effort  involves  substantial  risk.
Specifically,  future operating results will be subject to significant business,
liquidity,  economic,  regulatory,  technical, and competitive uncertainties and
contingencies.  The  integration  of the  components of the SKYCELL  System is a
complex  undertaking.  Delays in the  integration  of the  SKYCELL  System  have
already  occurred,  and there can be no assurance  that further  delays will not
occur.  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 operating results.


2.  Basis of Presentation

     The  consolidated   balance  sheet  as  of  September  30,  1996,  and  the
consolidated  statements  of loss  and cash  flows  for the  nine  months  ended
September  30, 1996 and 1995,  and for the period May 3, 1988 through  September
30, 1996,  have been prepared by the Company  without  audit.  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 September 30, 1996, and for all periods  presented have been made.
The balance sheet at December 31, 1995 has been taken from the audited financial
statements.

     The unaudited  consolidated  condensed financial statements included herein
have been prepared  pursuant to the rules and  regulations of the Securities and
Exchange  Commission.  Certain  information  and footnote  disclosures  normally
included in financial  statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. While the Company believes
that the  disclosures  made are adequate to make the  information  presented not
misleading,   these  consolidated   financial   statements  should  be  read  in
conjunction  with  the  consolidated  financial  statements  and  related  notes
included  in the  Company's  1995  Annual  Report  on Form  10-K  ("1995  Annual
Report").

     The  Company  paid  approximately  $6.6  million  and $3.6  million  in the
nine-month periods ended September 30, 1996 and 1995,  respectively,  to related
parties for  construction  and  service-related  obligations  and payments under
financing  agreements.  Payments  to related  parties  from May 3, 1988 (date of
inception) to September 30, 1996, aggregated approximately $163.7 million. Total
indebtedness  to related  parties as of  September  30, 1996  approximated  $8.5
million.

     Loss per common share is based on the weighted-average  number of shares of
Common  Stock  outstanding  during the period.  Stock  options and common  stock
purchase warrants are not reflected since their effect would be antidilutive.

     Certain  amounts for the three months and nine months ended  September  30,
1995  and for the  period  from  inception  to  September  30,  1996  have  been
reclassified to conform with the current period presentation.


3.  Liquidity and Financing

     Adequate  liquidity  and capital are critical to the ability of the Company
to transition  successfully  from being a development stage company to deploying
and operating the SKYCELL System. As previously reported,  on June 28, 1996, the
Company  established  a $225 million debt facility  with Morgan  Guaranty  Trust
Company and  Toronto  Dominion  Bank (the "Bank  Financing")  consisting  of two
facilities:  (i) a $150 million  five-year,  multi-draw  term loan facility (the
"Term Loan Facility") and (ii) a $75 million five-year revolving credit facility
with a bullet maturity on June 30, 2001 (the "Working Capital Facility").  As of
October 28,  1996,  the  Company  had drawn down $93.0  million of the Term Loan
Facility at annual interest rates ranging from 5.6875% to 5.75%. $200 million of
the Bank  Financing is guaranteed  (the  "Guarantee")  by three of the Company's
principal stockholders:  Hughes Electronics  Corporation  ("Hughes"),  Singapore
Telecommunications,  Ltd. and Baron Capital Partners,  L.P.  (collectively,  the
"Guarantors").  The Guarantors received compensation  consisting  principally of
cash fees and warrants (the "Guarantee  Warrants").  The Guarantee Warrants have
been valued at $19.0 million.

     Under the terms of the Bank Financing and the Guarantee,  borrowings  under
the Bank  Financing  in excess of  prescribed  levels  are  contingent  upon the
satisfaction  by the  Company  of  certain  performance  tests  relating  to net
revenues,  number  of  subscribers,  operating  cash  flow and  earnings  before
interest,  taxes,  depreciation  and  amortization.  During the third quarter of
1996,  the  Company  met the  required  performance  tests  except  for the test
relating  to net  revenues.  The  Company  has  received  a waiver  relating  to
satisfaction of that performance test and of a limitation on borrowing,  thereby
permitting  the Company to borrow up to $155 million  under the Bank  Financing.
This is expected to meet the Company's  financing needs through the remainder of
1996 and into 1997.

     Because of the slower than anticipated  build-up in subscribers and related
revenues,  it is currently expected that the Company will not meet the remaining
quarterly  Guarantor  performance  tests  under the Bank  Financing.  Therefore,
additional Guarantor waivers will be required under the Bank Financing.  Even if
the Company is successful in receiving  additional waivers, the Company may need
additional  financing in 1997 beyond the Bank  Financing.  No  assurance  can be
given that additional  waivers will be granted or that the terms of such waivers
will not be adverse to the Company, or that if additional financing is required,
that  such  financing  will be  available  or that  the  terms  thereof  will be
favorable to the Company.  If waivers are not granted,  or the Bank Financing is
not  sufficient,  the Company may not have  adequate  capital to fund its future
operations.

     Following  negotiations of certain existing vendor debt  arrangements  (the
"Vendor   Financing")   and  ground   segment   obligations   ("Ground   Segment
Obligations"),  aggregating  $11.1  million,  the Company has  arranged to defer
repayment of the Vendor Financing and a portion of the Ground Segment Obligation
from September 30, 1996, until various dates in 1997.

4.  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 both  complete and operate the
SKYCELL  System and operate  mobile data  terminals and mobile  telephones.  The
successful  operation of the SKYCELL System is dependent on a number of factors,
including the amount of L-band  spectrum made available to the Company  pursuant
to an international coordination process. The United States is currently engaged
in an international process of coordinating the Company's access to the spectrum
that the FCC has  assigned  to the  Company.  While the  Company  believes  that
substantial  progress has been made in the coordination process and expects that
the United  States  government  will be  successful  in securing  the  necessary
spectrum,  the process is not yet  complete.  The inability of the United States
government to secure  sufficient  spectrum  could have an adverse  effect on the
Company's financial position, results of operations, and its cash flows.

     The  Company  has  filed  applications  with  the FCC and  expects  to file
applications  in the future with respect to the operation of its SKYCELL  System
and certain types of mobile data terminals and mobile telephones. Certain of its
applications  pertaining to future service have been opposed. While the Company,
for various reasons,  believes that it will receive the necessary approvals on a
timely basis,  there can be no assurance  that the requests will be granted on a
timely  basis or that  they  will be  granted  on  conditions  favorable  to the
Company.  Any significant  changes to the applications  resulting from the FCC's
review process or any significant delay in their approval could adversely affect
the Company's financial position, results of operations, and its cash flows. The
Company's  license  requires  that it  comply  with a  construction  and  launch
schedule specified by the FCC for each of the three authorized  satellites.  The
second  and  third  satellites  are not in  compliance  with  the  schedule  for
commencement of construction.  The Company has asked the FCC to grant extensions
of the deadlines for the second and third satellites. Certain of these extension
requests  have  been  opposed  by third  parties.  The FCC has not  acted on the
Company's  requests.  The FCC has the authority to revoke the authorizations for
the second and third satellites and in connection with any such revocation could
exercise its authority to rescind the Company's  license.  The Company  believes
that the exercise of such authority to rescind the license is unlikely.

     In 1992, a former director of AMSC filed an Amended  Complaint  against the
Company alleging  violations of the Communications Act of 1934, as amended,  and
of the Sherman Act and breach of contract.  The suit seeks  damages for not less
than $100  million  trebled  under the  antitrust  laws plus  punitive  damages,
interest, attorneys' fees and costs. In mid-1992, the Company filed its response
denying all allegations.  The Company's motion for summary  judgement,  filed on
June 30,  1994,  was denied on April 18,  1996.  The matter has now been set for
trial beginning November 25, 1996. Management believes that the ultimate outcome
of this matter will not be material to the Company's financial position, results
of operations, or its cash flows.

     In October 1996, a vendor filed a complaint against the Company  concerning
the  production of  approximately  7,500 mobile data  terminals.  The suit seeks
damages in as yet an undetermined  amount.  Management believes that it will not
incur any material liabilities or obligations as a result of this suit in excess
of any existing  contractual  obligations  to such vendor which are reflected in
the  Company's maximum contractual inventory  commitments  described  in  Note 5
below.

5.  Other Matters

     At September 30, 1996, the Company had remaining contractual commitments to
purchase both mobile data  terminal inventory  and  mobile  telephone  inventory
in the maximum amount of $44.4 million.

     As previously reported, the satellite has, in the past, experienced certain
technological anomalies, most significantly with respect to its eastern beam. On
August 1,  1996,  the  Company  reached a  resolution  of the  claims  under its
satellite  insurance  contracts and policies and received proceeds in the amount
of $66.0  million  which were used to repay the  Working  Capital  Facility  and
portions of the Term Loan Facility and the Vendor Financing.  The carrying value
of the satellite was reduced by the net insurance proceeds, which will result in
a reduction of future  depreciation  charges  beginning in the third  quarter of
1996.  There  can  be no  assurance  that  the  satellite  will  not  experience
subsequent  anomalies  that  could  adversely  impact  the  Company's  financial
condition, results of operations and cash flows.








                          PART I--FINANCIAL INFORMATION

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


General

     The following discussion and analysis provides information which management
believes is relevant to an  assessment  and  understanding  of the  consolidated
financial  condition  and results of  operations  of American  Mobile  Satellite
Corporation  (with its  subsidiaries,  "AMSC" or the "Company").  The discussion
should be read in conjunction  with the  consolidated  financial  statements and
notes thereto.

     American Mobile  Satellite  Corporation was incorporated in May 1988. Since
May 1988, the Company has been a development stage company, engaged primarily in
the design,  development,  construction,  deployment  and  financing of a mobile
satellite  communications  system (the  "SKYCELL  System").  The SKYCELL  System
includes the Company's first satellite ("AMSC-1") launched successfully in April
1995, and a fixed  communications  ground segment (the "CGS"). In December 1995,
the Company began to introduce  certain voice  products and services,  including
its Satellite Telephone Service.

     In addition to  historical  information,  this Form 10-Q  Quarterly  Report
contains forward-looking  statements.  The forward-looking  statements contained
herein are subject to certain  risks and  uncertainties  that could cause actual
results  to  differ  materially  from  those  reflected  in the  forward-looking
statements.  Factors  that might cause such a  difference  include,  but are not
limited to, those  discussed in the "Factors that could affect Future  Operating
Results" and "Liquidity and Capital Resources"  sections.  Readers are cautioned
not to place undue reliance on these forward-looking  statements,  which reflect
management's  analysis  only as of the date hereof.  The Company  undertakes  no
obligation to publicly revise these forward-looking statements to reflect events
or  circumstances  that arise after the date hereof.  Readers  should  carefully
review the risk factors described in other documents the Company files from time
to time with the  Securities  and Exchange  Commission,  including the Form 10-K
Annual  Report to be filed by the Company  subsequent  to this Form 10-Q and any
Current Reports on Form 8-K filed by the Company.

Factors that could affect Future Operating Results

     The Company's  future  operating  results could be adversely  affected by a
number of  uncertainties  and factors,  including (i) the timely  completion and
deployment of all the Company's  products and related services,  including among
other  things,  availability  of mobile  telephones,  data  terminals  and other
equipment  to be used with the SKYCELL  System  ("Subscriber  Equipment")  being
manufactured by third parties over which the Company has limited  control,  (ii)
the market  acceptance  of the  Company's  services,  (iii) the  ability and the
commitment of the Company's  Authorized  Service  Providers and Authorized Sales
Agents to market and distribute the Company's  services,  (iv)  competition from
existing   companies  which  provide  services  using  existing   communications
technologies  and the  possibility  of  competition  from  companies  using  new
technology   in  the  future,   (v)  capacity   constraints   arising  from  the
reconfiguration  of  AMSC-1  previously  reported,   (vi)  additional  technical
anomalies that may occur within the SKYCELL System,  including those relating to
AMSC-1,  which could impact,  among other  things,  the operation of the SKYCELL
System and the cost,  scope or  availability  of in-orbit  insurance,  (vii) the
ability of the Company to fully integrate certain  components of the mobile data
service,  and (viii) the Company's ability to obtain additional waivers from the
Bank Financing Guarantors or secure additional financing as may be necessary.

     The Company's  operating  results and capital and liquidity needs have been
materially  affected by delays  experienced in the development and deployment of
the SKYCELL System.  In particular,  the Company's  marketing  efforts have been
materially affected by delays experienced in the development and availability of
Subscriber  Equipment.  Initial  Subscriber  Equipment for  Satellite  Telephone
Service  ("STS")  use did  not  become  commercially  available  until  December
1995,with  additional  configurations  not available  until the second and third
quarters of 1996.  In addition,  the CGS  currently  does not support  facsimile
capability.  The  Company  anticipates  that  facsimile  capability  will become
available  in the first  quarter  of 1997.  The  impact  of these  delays on the
Company's   marketing   efforts  has   substantially   decreased  the  Company's
anticipated revenues and increased the Company's capital and liquidity needs. No
assurance can be given that additional  delays relating to the SKYCELL System or
Subscriber  Equipment will  not be  encountered  in the  future  and not have an
adverse impact on the Company.

     In  addition,  the  markets  for  wireless   communications   services  are
characterized by rapid  technological  and other changes.  The Company's success
depends,  in part,  on its  ability to respond  and adapt to such  changes.  The
delays  experienced in the deployment of the SKYCELL System and the availability
of  Subscriber  Equipment,  together  with  changes in market  conditions,  have
already  caused the Company to shift its  marketing  focus away from its initial
dual-mode consumer product business to targeted business  applications,  such as
the  maritime,   natural  resources,   transportation,   and  telecommunications
industries.  The Company  continues to expect that sales and marketing  expenses
will continue to increase from  previous  levels in 1995 as increased  resources
are devoted to its subscriber  acquisition  programs and sales personnel.  As of
September 30, 1996, there were  approximately  13,400 subscribers on the SKYCELL
System.  Charges to operations for  depreciation  expense for the SKYCELL System
began in the fourth quarter of 1995 and accordingly,  it is expected that future
charges   will  be   significant.   Additionally,   the   Company   discontinued
capitalization  of  interest  costs  in the  fourth  quarter  of 1995  upon  the
commencement of full commercial service. Interest expense in 1996 is expected to
be  significant  as a result of  borrowings  under the  Interim  Financing,  the
Short-Term Notes, and the Bank Financing.


Results of Operations

Operating Revenues

     Service revenues, which include both the Company's voice and data services,
approximated  $2.5 million and $6.1 million for the  three-month  and nine-month
periods  ended  September  30, 1996,  respectively.  Service  revenue from voice
services  approximated $1.1  million  and $2.9  million for the  three-month and
nine-month periods ended September 30, 1996 including approximately $1.3 million
for the nine-month  period ended  September 30, 1996  attributable  to satellite
capacity leased to TMI Communications and Company,  Limited Partnership ("TMI"),
a Canadian  limited  partnership,  under a commitment which was completed in May
1996. Service revenue from the Company's data services approximated $1.4 million
and $3.2 million for the three-month and nine-month  periods ended September 30,
1996,  respectively,  compared  to $1.6  million  and $5.2  million for the same
period in 1995, a reduction of $256,000 and $2.0 million respectively.  Prior to
1996, the Company provided its data service using satellite capacity leased from
the  Communications  Satellite  Corporation  ("COMSAT"),  the cost of which  was
passed through to one customer ("Major Customer").  The decrease in data service
revenue of $2.0  million  for the  nine-month  period  ended  September  30,1996
reflects  the  reduced  revenue  from the Major  Customer  resulting  from lower
billings for the use of the lower cost AMSC-1 versus  billings  attributable  to
the leased COMSAT satellite applied on a pass-through basis. Of the data service
revenues,  29% and 39% were  attributable  to the Major  Customer  for the three
months and nine months ended September 30, 1996,  respectively,  compared to 80%
and 75% for the respective periods in 1995. Revenue from the sale of mobile data
terminals  and mobile  telephones  increased  from $438,000 for the three months
ended  September  30, 1995 to $4.9 million for the three months ended  September
30, 1996, and increased to $12.5 million for the nine months ended September 30,
1996  compared  to  $504,000  for the same  period  in 1995.  This  increase  is
attributable to (i) the Company's  introduction of certain voice products in the
fourth quarter of 1995 and the resulting sale of mobile telephones, and (ii) the
increased  availability  of mobile data  terminals in 1996 compared to the first
nine  months of 1995  following a contract  signed  with a mobile data  terminal
manufacturer in February 1995.

Costs and Expenses

     The  Company's  costs and expenses have  primarily  increased in connection
with the  commencement  of full  commercial  service in December  1995.  Cost of
service  and  operations  for  the  three-month  and  nine-month  periods  ended
September 30, 1996,  which includes costs to support  subscribers and to operate
the SKYCELL  System,  were $7.6 million and $23.3  million,  respectively,  $3.3
million and $10.7 million  greater than the comparable  periods in 1995. Cost of
service  and  operations  for  the  three-month  and  nine-month  periods  ended
September  30, 1996 were 22% and 21%, as a  percentage  of  operating  expenses,
compared to 28% and 34% for the comparable  periods in 1995. The dollar increase
in cost of service and operations was primarily  attributable  to (i) additional
personnel and related costs to support both  existing and  anticipated  customer
demand,  (ii) increased costs  associated  with the on-going  maintenance of the
Company's  billing  systems  and the CGS,  and (iii) $4.8  million of  insurance
expense for in-orbit insurance coverage for AMSC-1, offset by the elimination of
COMSAT lease expense  reflecting the transition of the Company's  customers from
the leased  satellite  to AMSC-1.  The  decrease as a  percentage  of  operating
expenses was attributable to the overall  increase in total operating  expenses.
The cost of equipment sold increased to $6.2 million from $599,000 for the three
months ended  September  30, 1996 and 1995,  respectively,  and to $23.1 million
from  $757,000  for  the  nine  months  ended   September  30,  1996  and  1995,
respectively,  and represented  18% and 4% of total  operating  expenses for the
three  months  ended  September  30,  1996  and  1995,  and  21%  and 2% for the
nine-month periods ended September 30, 1996 and 1995, respectively. The increase
in both  dollars  and as a  percentage  of  operating  expenses  of the  cost of
equipment sold is primarily  attributable  to (i) the Company's  introduction of
certain voice  products in the fourth  quarter of 1995 and the resulting sale of
mobile  telephones,  (ii) the  availability  of mobile  data  terminals  in 1996
compared to the first nine months of 1995,  (iii) a $4.0  million  charge in the
second quarter of 1996 for the  reconfiguration of certain inventory  components
to better meet customer  requirements,  and (iv) $4.8 million  writedowns in the
second and third quarters of 1996 of certain assets, including inventory, to net
realizable  value.  Sales and  advertising  expenses were $5.7 million and $18.0
million for the  three-month  and nine-month  periods ended  September 30, 1996,
respectively,  compared  with $5.4 million and $8.9 million for the same periods
in 1995.  Sales and  advertising  expenses for the  three-month  and  nine-month
periods ended September 30, 1996 were 17% and 16%, respectively, as a percentage
of operating  expenses,  compared to 35% and 24% for the  comparable  periods in
1995.  The dollar  increase of sales and  advertising  expenses  were  primarily
attributable to (i) additional head count and personnel related costs associated
with the increase in sales staff,  and (ii) increased costs directly  associated
with the increased  subscriber  acquisition  programs,  offset by a $1.4 million
charge,  in 1995,  associated  with the  re-acquisition  of defective  equipment
located at a customer site and settlement of related disputes. The decrease as a
percentage of operating  expenses was  attributable  to the overall  increase in
total  operating   expenses.   General  and  administrative   expenses  for  the
three-month  and nine-month  periods ended  September 30, 1996 were $4.2 million
and $13.6  million,  respectively,  $210,000 and $2.0  million  greater than the
comparable  periods  in  1995.  General  and  administrative  expenses  for  the
three-month  and nine-month  periods ended  September 30, 1996 were 13% and 12%,
respectively, as a percentage of operating expenses, compared to 26% and 32% for
the same  periods in 1995.  The dollar  increase in general  and  administrative
expenses  for the first  nine  months  of 1996  compared  to 1995 was  primarily
attributable to a $2.1 million  increase in  personnel-related  costs associated
with (i) hiring  and  training  staff to support  full  commercial  service  and
increased  facilities and related support costs  approximating  $1.4 million and
(ii)  approximately  $675,000 of severance  costs  associated  with a management
restructuring.  The  decrease  of  general  and  administrative  expenses  as  a
percentage of operating  expenses was  attributable  to the overall  increase in
total  operating  expenses.  Depreciation  and  amortization  expense  was $10.0
million and $33.0  million for the  three-month  and  nine-month  periods  ended
September  30, 1996,  respectively,  compared with $1.2 million and $2.9 million
for the  same  periods  in  1995.  Depreciation  and  amortization  for both the
three-month  and  nine-month  periods  ended  September  30, 1996 were 30%, as a
percentage of operating expenses, compared with 7% and 8%, respectively, for the
comparable  periods in 1995.  Both the dollar  increase  and the  increase  as a
percentage of operating  expenses in depreciation and amortization  expense were
attributable  to the  commencement  of  depreciation  of both AMSC-1 and related
assets and the CGS in the fourth quarter of 1995.


Interest

     Interest income was $180,000 and $485,000 in the three-month and nine-month
periods  ended  September 30, 1996,  respectively,  compared to $1.0 million and
$4.1 million in the same periods in 1995.  The decreases  were a result of lower
average  cash  balances in the first nine months of 1996.  The Company  incurred
$3.7  million and $11.4  million of interest  expense  for the  three-month  and
nine-month  periods  ended  September  30,  1996,  respectively,  compared to no
interest  expense  for  the  comparable  periods  of  1995  reflecting  (i)  the
discontinuation  of interest cost  capitalization  as a result of  substantially
completing  the  SKYCELL  System in the  fourth  quarter  of 1995,  and (ii) the
amortization of debt discount in the first nine months of 1996 of  approximately
$4.0 million.

Capital Expenditures

     Net  capital  reductions,   including  additions  financed  through  vendor
financing  arrangements,  for the first nine  months of 1996 were $61.9  million
compared to capital  expenditures  of $71.6 million for the same period in 1995.
The decrease was largely  attributable  to (i) the net proceeds of $65.3 million
from the  resolution  of the  claims  under the  Company's  satellite  insurance
contracts  and  policies  (see  "Liquidity  and  Capital  Resources"),  (ii) the
purchase,  in the first  quarter of 1995,  of launch  insurance at a cost to the
Company of $42.8 million in connection  with the Company's  launch contract with
Martin  Marietta  Commercial  Launch  Services,  Inc., and (iii) the decrease in
construction  activity as certain components of the  Communications  System were
completed in 1995.

Liquidity and Capital Resources

     Adequate  liquidity  and capital are critical to the ability of the Company
to transition  successfully  from being a development stage company to deploying
and operating the SKYCELL System. As previously reported,  on June 28, 1996, the
Company  established  a $225 million debt facility  with Morgan  Guaranty  Trust
Company and  Toronto  Dominion  Bank (the "Bank  Financing")  consisting  of two
facilities:  (i) a $150 million  five-year,  multi-draw  term loan facility (the
"Term Loan Facility") and (ii) a $75 million five-year revolving credit facility
with a bullet maturity on June 30, 2001 (the "Working Capital Facility").  As of
October 28,  1996,  the  Company  had drawn down $93.0  million of the Term Loan
Facility at annual interest rates ranging from 5.6875% to 5.75%. $200 million of
the Bank  Financing is guaranteed  (the  "Guarantee")  by three of the Company's
principal stockholders:  Hughes Electronics  Corporation  ("Hughes"),  Singapore
Telecommunications,  Ltd. and Baron Capital Partners,  L.P.  (collectively,  the
"Guarantors").  The Guarantors received compensation  consisting  principally of
cash fees and warrants (the "Guarantee  Warrants").  The Guarantee Warrants have
been valued at $19.0 million.

     Under the terms of the Bank Financing and the Guarantee,  borrowings  under
the Bank  Financing  in excess of  prescribed  levels  are  contingent  upon the
satisfaction  by  the  Company  of  certain  performance  test  relating  to net
revenues,  number  of  subscribers,  operating  cash  flow and  earnings  before
interest,  taxes,  depreciation  and  amortization.  During the third quarter of
1996,  the  Company  met the  required  performance  tests  except  for the test
relating  to net  revenues.  The  Company  has  received  a waiver  relating  to
satisfaction of that performance test and of a limitation on borrowing,  thereby
permitting  the Company to borrow up to $155 million  under the Bank  Financing.
This is expected to meet the Company's  financing needs through the remainder of
1996 and into 1997.

     Because of the slower than anticipated  build-up in subscribers and related
revenues,  it is currently expected that the Company will not meet the remaining
quarterly  Guarantor  performance  tests  under the Bank  Financing.  Therefore,
additional Guarantor waivers will be required under the Bank Financing.  Even if
the Company is successful in receiving  additional waivers, the Company may need
additional  financing in 1997 beyond the Bank  Financing.  No  assurance  can be
given that additional  waivers will be granted or that the terms of such waivers
will not be adverse to the Company, or that if additional financing is required,
that  such  financing  will be  available  or that  the  terms  thereof  will be
favorable to the Company.  If waivers are not granted,  or the Bank Financing is
not  sufficient,  the Company may not have  adequate  capital to fund its future
operations.

     Following  negotiations of certain existing vendor debt  arrangements  (the
"Vendor   Financing")   and  ground   segment   obligations   ("Ground   Segment
Obligations"),  aggregating  $11.1  million,  the Company has  arranged to defer
repayment of the Vendor Financing and a portion of the Ground Segment Obligation
from September 30, 1996, until various dates in 1997.

     As previously  reported,  the Company filed a claim for indemnity under its
launch insurance with respect to the anomalies leading to the reconfiguration of
AMSC-1.On  August 1, 1996, the Company  reached a resolution of the claims under
its satellite insurance  contracts and policies,  and received gross proceeds in
the  amount  of $66.0  million  which  were used to repay  the  Working  Capital
Facility and portions of the Term Loan  Facility and the Vendor  Financing.  The
carrying  value of the  satellite was reduced by the amount of the net insurance
proceeds,  which  will  result in a  reduction  of future  depreciation  charges
beginning in the third quarter of 1996.

     At September 30, 1996, the Company had remaining contractual commitments to
purchase both mobile data  terminal  inventory  and mobile  telephone  inventory
in the maximum amount of $44.4 million.

     For the period from inception  through  September 30, 1996, the Company has
used $200.3  million of cash in operating  activities and $262.5 million of cash
in investing  activities and has generated $465.2 million of cash from financing
activities.  The Company's primary  investing  activity since inception has been
capital expenditures related to the SKYCELL System. The Company has financed its
capital and operating  requirements  through a  combination  of private debt and
equity  placements,   a  public  equity  offering,   borrowings  from  financial
institutions, and vendor financing arrangements.

     Cash used in  operating  activities  was $74.6  million  for the first nine
months of 1996  compared  to cash used of $29.3  million  for the same period in
1995,  an  increase of $45.3  million.  The  increase in cash used in  operating
activities was primarily  attributable to (i) increased  operating losses,  (ii)
increased  trade  receivables  as a result of  increased  equipment  and service
revenue,  and (iii) increased  inventory  acquisitions of subscriber  equipment,
partially  offset by the net increase in operating  accounts payable and accrued
expenses.  Cash provided by investing activities was $54.6 million for the first
nine months of 1996  compared to cash used of $50.2  million for the same period
in 1995, an increase of $104.8 million. The increase was primarily  attributable
to (i) the  receipt of  proceeds  from the  resolution  of the claims  under the
Company's  satellite  insurance  contracts  and  policies,  (ii) the decrease in
construction activity in 1996, and (iii) the purchases,  in the first quarter of
1995,  of $42.8  million of launch  insurance,  offset  partially by the sale of
$28.7  million of  short-term  investments  in the first  quarter of 1995.  Cash
provided by financing  activities was $13.6 million for the first nine months of
1996 compared to cash used in financing  activities of $2.3 million for the same
period  in 1995,  an  increase  of  $15.9  million.  The  increase  was  largely
attributable  to the $77.0 million of borrowings  under the Term Loan  Facility,
offset by the  repayment of $40.0  million of long-term  debt and the payment of
$10.6  million  of costs  associated  with  the  acquisition  of the  Term  Loan
Facility.  As of September  30,  1996,  the Company had $2.4 million of cash and
cash equivalents and a working capital deficit of $21.5 million.

Technological Developments

     As previously reported, the satellite has, in the past, experienced certain
technological  anomalies,  most  significantly  with respect to its eastern beam
which resulted in the Company's  receipt of $66.0 million of insurance  proceeds
as discussed  above (see  "Liquidity  and Capital  Resources").  There can be no
assurance that the satellite will not experience subsequent anomalies that could
adversely impact the Company's  financial  condition,  results of operations and
cash flows.
