                 Financial Condition and Results of Operations
                 ---------------------------------------------

This Annual Report on Form 10-K includes "forward-looking statements" within the
meaning of Section  27A of the  Securities  Act of 1933 and  Section  21E of the
Securities  Exchange Act of 1934.  Such  statements are identified by the use of
forward-looking  words or phrases  including,  but not limited  to,  "believes,"
"intended,"   "will  be   positioned,"   "expects,"   "expected,"   "estimates,"
"anticipates" and "anticipated." These  forward-looking  statements are based on
the Company's  current  expectations.  All statements  other than  statements of
historical  facts included in this Annual Report,  including those regarding the
Company's financial position,  business strategy,  projected costs and financing
needs,  and plans and  objectives  of  management  for  future  operations,  are
forward-looking statements.  Although the Company believes that the expectations
reflected in such  forward-looking  statements are  reasonable,  there can be no
assurance  that  such  expectations  will  prove to have been  correct.  Because
forward-looking statements involve risks and uncertainties, the Company's actual
results  could  differ  materially.  Important  factors  that could cause actual
results  to  differ  materially  from the  Company's  expectations  ("Cautionary
Statements")  are disclosed under  "Business" and  "Management's  Discussion and
Analysis of Financial  Condition  and Results of  Operations,"  and elsewhere in
this Annual Report,  including,  without  limitation,  in  conjunction  with the
forward-looking statements included in this Annual Report. These forward-looking
statements  represent the  Company's  judgment as of the date hereof and readers
are cautioned not to place undue reliance on these  forward-looking  statements.
All subsequent written and oral forward-looking  statements  attributable to the
Company or persons  acting on behalf of the Company are  expressly  qualified in
their entirety by the Cautionary Statements. 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 Current Report on
Form 8-K filed on March 9, 1998, and Form 10-Q Quarterly  Reports to be filed by
the Company  subsequent to this Form 10-K Annual Report and any Current  Reports
on Form 8-K and registration statements filed by the Company.


General
- -------

The following  discussion and analysis  provides  information  which  management
believes  is  relevant  to an  assessment  and  understanding  of the  financial
condition and  consolidated  results of operations of American Mobile  Satellite
Corporation  (with its subsidiaries,  "American  Mobile" 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 and, until
1996,  was a  development  stage  company,  engaged  primarily  in  the  design,
development,  construction,  deployment  and  financing  of a  mobile  satellite
communication  system.  On December 31, 1997,  the Company  entered into a Stock
Purchase Agreement (the "Purchase Agreement") with Motorola,  Inc. ("Motorola"),
for  the  acquisition  (the   "Acquisition")  of  ARDIS  Company  ("ARDIS"),   a
wholly-owned  subsidiary of Motorola  that owns and operates a two-way  wireless
data  communications  network.  On March 3,  1998,  the FCC  granted  consent to
consummate  the  Acquisition.  On March 31, 1998,  the  Acquisition  and related
financing  were  completed.  See  "Liquidity  and Capital  Resources."  With the
acquisition  of ARDIS,  the Company  becomes a leading  provider  of  nationwide
wireless communications  services,  including data, dispatch and voice services,
primarily to business  customers in the United States.  The Company will offer a
broad  range of  end-to-end  wireless  solutions  utilizing  a seamless  network
consisting of the nation's largest,  most  fully-deployed  terrestrial  wireless
data network (the "ARDIS Network") and a satellite in geosynchronous  orbit (the
"Satellite Network") (together, the "Network").

In connection with the  Acquisition,  the Company and its  subsidiaries  entered
into agreements with respect to the following  financings and refinancings:  (1)
$335  million of Units;  (2) the  restructuring  of its  existing  $200  million
Revolving  Credit Facility and Term Loan Facility  (collectively,  the "New Bank
Financings");  and (3) $10 million  commitment  with respect to Motorola  vendor
financing.  See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Liquidity and Capital Resources."


                                       F-1

On October 16, 1997,  American Mobile Radio Corporation,  an indirect subsidiary
of American  Mobile through its subsidiary  AMRC Holdings,  Inc.  (together with
American Mobile Radio Corporation,  "AMRC"), was awarded a license by the FCC to
provide  satellite-based  Digital Audio Radio Service  ("DARS")  throughout  the
United States, following its successful $89.9 million bid at auction on April 2,
1997.  American  Mobile has entered  into an  agreement  with  WorldSpace,  Inc.
("WorldSpace"), by which WorldSpace has acquired a 20% participation in AMRC. In
connection  with the DARS  auction,  AMRC has also arranged for financing of the
FCC license fees as well as for initial working  capital needs,  which financing
has included the issuance of options.  Under the terms of AMRC's  financing  and
contingent on FCC approval,  exercise of the  outstanding  issued  options could
result in the dilution of American Mobile's  ownership  interest in AMRC to 28%.
Additionally,  the agreement gives WorldSpace certain participation rights which
provide  for  their  participation  in  significant  business  decisions  in the
ordinary course of business.  As a result, AMRC is carried on the equity method.
The operations and financing of AMRC are maintained  separate and apart from the
operations and financing of American Mobile (see "Liquidity and Financing").

On  December  4, 1997,  the  Company  entered  into an  agreement  with  African
Continental  Telecommunications Ltd. ("ACTEL") to lease the Company's satellite,
"MSAT-2" (the  "Satellite  Lease  Agreement")  for deployment  over  sub-Saharan
Africa.  Simultaneously,  the Company agreed with TMI Communications and Company
Limited  Partnership  ("TMI") to acquire a one-half  ownership interest in TMI's
satellite,  "MSAT-1" (the "Satellite Purchase Agreement"). See Item I. "Business
- -- Satellite Lease and Purchase Agreement", "-Satellite Back-up and Technology,"
and Management's  Discussion and Analysis of Financial  Condition and Results of
Operations - Liquidity and Capital Resources."

In late  1996  the  Company  expanded  its  mobile  data  business  through  the
acquisition  of  Rockwell  International  Corporation's  ("Rockwell")  dual mode
mobile  messaging and global  positioning and monitoring  service for commercial
trucking fleets  ("MCSS").  In the transaction,  the Company assumed  Rockwell's
existing customer contracts,  and acquired Rockwell's system  infrastructure for
delivering  their  mobile  data  product,  as well as  Rockwell's  rights to the
multi-mode,  satellite-terrestrial  product.  The  assets of the  business  were
acquired  through the  assumption of the various  contracts and  obligations  of
Rockwell relating to the business;  no additional payments were made to Rockwell
under the terms of the Asset Sale  Agreement  dated as of November 22, 1996. See
"Liquidity and Capital Resources."

Management  believes the period to period comparison of the Company's  financial
results  are not  necessarily  meaningful  and should  not be relied  upon as an
indication of future  operating  performance  due to the Company's  historically
high growth rate and the acquisition of MCSS and ARDIS.


Overview
- --------

Each of American Mobile and ARDIS has incurred significant  operating losses and
negative cash flows in each year since it commenced operations, due primarily to
start-up  costs,  the costs of developing and building each network and the cost
of developing,  selling and providing its respective products and services.  The
Company is, and will continue to be, highly leveraged.  As of December 31, 1997,
on a pro forma basis,  the Company would have had  indebtedness of approximately
$454.9 million,  assuming the  Acquisition,  the issuance of the $335 million of
Units, and restructuring of the bank financing (see "Recent Financing Activity")
occurred on December 31, 1997.

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  future  products  and  related  services,   including  among  other  things,
availability of mobile telephones, data terminals and other equipment to be used
with the Network  ("Subscriber  Equipment") being  manufactured by third parties
over which the Company has limited control,  (ii) the market's acceptance of the
Company's  services,  (iii) the  ability  and the  commitment  of the  Company's
distribution channels to market and distribute the Company's services,  (iv) the
Company's  ability to modify  its  organization,  strategy  and  product  mix to
maximize the market  opportunities in light of changes therein,  (v) competition
from existing  companies that provide  services  using  existing  communications
technologies  and the  possibility  of  competition  from  companies  using  new
                                       F-2

<PAGE>


technology  in  the  future,   (vi)  capacity   constraints   arising  from  the
reconfiguration of MSAT-2,  subsequent anomalies affecting MSAT-2 and MSAT-1, or
the power management  recommendation affecting both MSAT-2 and MSAT-1 previously
reported,  (vii)  additional  technical  anomalies  that may  occur  within  the
Satellite  Network,  including those relating to MSAT-1 and MSAT-2,  which could
impact, among other things, the operation of the Satellite Network and the cost,
scope  or  availability  of  in-orbit  insurance,  (viii)  subscriber  equipment
inventory  responsibilities and liabilities assumed by the Company including the
ability of the Company to realize the value of its inventory in a timely manner,
(ix) the Company's ability to secure  additional  financing as may be necessary,
(x) the  Company's  ability to respond and react to changes in its  business and
the  industry  as a result of being  highly  leveraged,  (xi) the ability of the
Company  to  successfully  integrate  ARDIS  and  to  achieve  certain  business
synergies, and (xii) the ability of the Company to manage growth effectively.

The  Company's  operating  results  and capital  and  liquidity  needs have been
materially  affected by delays experienced in the acquisition of subscribers and
the related  equipment  sales. As a result,  the Company shifted from a consumer
focus to a business  to business  focus in late 1996.  Such shift has caused the
Company to refocus certain  business  resources and to re-organize the sales and
marketing organization. The impact of this delay 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
acquisition of subscribers  and delayed  equipment sales will not be encountered
in the future and not have an adverse impact on the Company.

As of December 31, 1997, there were approximately  32,400 units on the Satellite
Network.


Years Ended December 31, 1997 and 1996
- --------------------------------------

Service  revenues,  which  include both the Company's  voice and data  services,
approximated  $20.7  million for 1997 as  compared to $9.2  million for 1996 and
represents a 125% increase year over year.  Service  revenue from voice services
increased 100% from  approximately  $5.0 million in 1996 to approximately  $10.0
million in 1997.  The $5.0  million  increase  was  primarily a result of a 101%
increase in voice customers during 1997. Service revenue from the Company's data
services  approximated  $7.6  million in 1997,  as compared to $2.3  million for
1996,  an increase of $5.4 million or 245%.  The increase was primarily a result
of  additional  revenue  from  dual  mode  subscribers  added as a result of the
acquisition,  on November  1996,  of Rockwell's  dual mode mobile  messaging and
global positioning and monitoring  service,  as compared to the revenue received
in 1996 for satellite capacity leased by Rockwell. Service revenue from capacity
resellers, who handle both voice and data services, approximated $2.8 million in
1997,  as compared to $1.8 million in 1996,  an increase of $1.0 million or 56%.
As of December 31, 1997 and 1996,  receivables relating to service revenues were
$3.6 million and $1.8 million, respectively.

Revenue from the sale of mobile data terminals and mobile  telephones  increased
27% from  $18.5  million  in 1996 to $23.5  million in 1997.  The  increase  was
primarily  attributable  to increased  equipment  sales of the dual-mode  mobile
messaging  product,   discussed  above.  As  of  December  31,  1997  and  1996,
receivables  relating to  equipment  revenue  were $5.9 million and $5.8 million
respectively.

Cost of  service  and  operations  for 1997,  which  includes  costs to  support
subscribers  and to operate the Satellite  Network,  were $32.0 million for 1997
and $30.5 million for 1996. Cost of service and operations for 1997 and 1996, as
a percentage of revenues, were 72% and 110%, respectively.  The increase in cost
of  service  and  operations  was  primarily   attributable   to  (i)  increased
interconnect  charges associated with increased service usage by customers,  and
(ii) the  additional  cost  associated  with  supporting  the dual  mode  mobile
messaging  product  discussed  above,  offset  by  a  reduction  in  information
technology  costs  affected by  dramatically  reducing the dependence on outside
consultants.

The cost of equipment  sold  increased  26% from $31.9  million in 1996 to $40.3
million in 1997. The dollar  increase in the cost of equipment sold is primarily
attributable  to (i) increased  sales as a result of the acquisition of the dual
mode messaging product, (ii) an increase of $600,000 in inventory carrying costs
as certain  subscriber  equipment  contracts were  fulfilled,  and (iii) a $12.0

                                       F-3

million write down of inventory to net  realizable  value in 1997 as compared to
$11.1 million write down and reconfiguration charges in 1996.

Sales and  advertising  expenses were $12.1  million in 1997,  compared to $24.5
million in 1996. Sales and advertising  expenses as a percentage of revenue were
27% in 1997 and 88% in 1996. The decrease of sales and advertising  expenses was
primarily  attributable  to (i) a more focused  approach to  advertising  as the
company has moved from consumer markets to targeted  business-to-business sales,
and the resulting  reduction in print  advertising,  (ii) increased costs in the
first  quarter of 1996 for the  development  of  collateral  material  needed to
support the sales effort,  and (iii) costs incurred in the first quarter of 1996
associated with the formal launch of service.

General and  administrative  expenses for 1997 were $14.8  million,  compared to
$17.5 million in 1996. As a percentage  of revenue,  general and  administrative
expenses  represented  34% in 1997 and 63% in 1996.  The decrease in general and
administrative  expenses for 1997 compared to 1996 was primarily attributable to
reductions  made in staffing as a result of a  management  restructuring  in the
third quarter of 1996 and the associated severance costs.

Depreciation  and  amortization  expense was $42.4  million and $43.4 million in
1997 and 1996, respectively,  representing approximately 96% and 156% of revenue
for 1997 and 1996,  respectively.  The overall dollar and percentage decrease in
depreciation and  amortization  expense was attributable to the reduction of the
carrying value of the satellite as a result of the  resolution,  in August 1996,
of claims under the Company's satellite insurance contracts and policies and the
receipt  of  approximately  $66.0  million,  offset by a $1.0  million  one-time
charge, in the second quarter of 1997, associated with increased amortization in
accordance with SFAS No.86 of certain cost associated with software  development
for the mobile data product.

Interest  income was $247,000 in 1997 compared to $552,000 in 1996. The decrease
was a result of lower average cash balances.  The Company incurred $21.6 million
of interest  expense in 1997  compared to $15.2  million of interest  expense in
1996 reflecting (i) the amortization of debt discount and debt offering costs in
the amount of $9.4 million in 1997,  compared to $5.7 million in 1996,  and (ii)
higher  outstanding loan balances as compared to 1996.  During 1997, the Company
received other income in the amount of $875,000  representing  proceeds from the
licensing of certain technology associated with the Satellite Network.

Interest  expense in 1997 was  significant  as a result of borrowings  under the
Bank  Financing,  as well as the  amortization  of borrowing  costs  incurred in
conjunction  with securing the facility.  It is anticipated  that interest costs
will  continue  to be  significant  as a result  of the Bank  Financing,  Bridge
Financing, and Acquisition, (see "Liquidity and Capital Resources").

Net capital expenditures,  including additions financed through vendor financing
arrangements,  for 1997 for property and equipment were $8.8 million compared to
capital  reductions  of $51.0 million in 1996.  The $59.4  million  increase was
largely  attributable  to (i) the net proceeds in 1996 of $66.0 million from the
resolution of the claims under the Company's  satellite  insurance contracts and
policies (see "Liquidity and Capital  Resources") and (ii) the decrease in asset
acquisitions  associated with the final build-out of the  communications  ground
segment (the "CGS").


Years Ended December 31, 1996 and 1995
- --------------------------------------

Service  revenues,  which  include both the Company's  voice and data  services,
approximated  $9.2  million for 1996 as compared to $6.9  million for 1995 which
represents a 33% increase year over year.  Service  revenue from voice  services
approximated  $5.0  million  in  1996,  including   approximately  $1.3  million
attributable to satellite  capacity leased to TMI, under a commitment  which was
completed  in May 1996.  Service  revenue from the  Company's  data and position
location  services  ("Mobile  Data  Communication  Service")  approximated  $2.2
million in 1996,  as compared to $1.7 for 1995,  an increase of $500,000 or 29%.
Service revenue from capacity resellers who handle both voice and data services,
approximated  $1.8  million in 1996,  as  compared  to $5.2  million in 1995,  a
decrease of $3.4 million or 65%. Prior to 1996, the Company  provided its Mobile

                                       F-4

<PAGE>


Data   Communication   Service  using   satellite   capacity   leased  from  the
Communications  Satellite Corporation  ("COMSAT"),  the cost of which was passed
through to one  customer  (Rockwell).  The  decrease  in revenue  from  capacity
resellers  reflects  the reduced  revenue  from  Rockwell  resulting  from lower
billings for the use of the lower cost MSAT-2 versus  billings  attributable  to
the leased  COMSAT  satellite  applied on a  pass-through  basis.  As previously
discussed,  the  Company  acquired  the dual mode  mobile  messaging  and global
positioning and monitoring service of Rockwell in November 1996. At December 31,
1996 and 1995,  receivables relating to service revenues were $1.8 and $405,000,
respectively.

Revenue from the sale of mobile data terminals and mobile  telephones  increased
from $1.9 million in 1995 to $18.5 million in 1996,  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,  and (ii) the  increased
availability  of mobile data  terminals  in 1996  compared  to 1995  following a
contract signed with a mobile data terminal manufacturer in February 1995.

The Company's costs and expenses have primarily increased in connection with the
start  of  full  commercial  service  in  December  1995.  Cost of  service  and
operations for 1996, which includes costs to support  subscribers and to operate
the Satellite Network,  were $30.5 million for 1996, an increase of $6.5 million
from 1995.  Cost of service and operations for 1996 and 1995, as a percentage of
revenue were 110% and 272%, respectively. 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) $6.5  million of  insurance  expense for
in-orbit  insurance  coverage for MSAT-2,  offset by the  elimination  of COMSAT
lease expense  reflecting  the  transition of the Company's  customers  from the
leased satellite to MSAT-2.

The cost of equipment  sold increased to $31.9 million in 1996 from $4.7 million
in 1995. The increase in 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 1995,  (iii) a $4.2 million charge in
1996 for the  reconfiguration  of certain  components  to better  meet  customer
requirements,  and (iv) a $6.9 million write down of inventory to net realizable
value in 1996.

Sales and  advertising  expenses were $24.5  million in 1996,  compared to $22.8
million in 1995. Sales and advertising  expenses as a percentage of revenue were
88% in 1996 and 259% in 1995. The increase of sales and advertising expenses was
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 increase in 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.

General and administrative  expenses for 1996 were $17.5 million, an increase of
$0.8  million as  compared to 1995.  As a  percentage  of  revenue,  general and
administrative  expenses  represented  63% in 1996 and 190% in 1995.  The dollar
increase in general and  administrative  expenses for 1996  compared to 1995 was
primarily   attributable  to  (i)  approximately  $675,000  of  severance  costs
associated  with a management  restructuring  and (ii) an increase in facilities
rents and  utilities  of $236,000.  The  decrease of general and  administrative
expenses as a percentage of operating  expenses was  attributable to the overall
increase in operating expenses.

Depreciation  and  amortization  expense was $43.4  million and $11.2 million in
1996 and 1995, respectively, representing approximately 156% and 128% of revenue
for 1996 and 1995,  respectively.  The increase in depreciation and amortization
expense was  attributable to the commencement of depreciation of both MSAT-2 and
related assets and the CGS in the fourth quarter of 1995.

Interest and other income was $552,000 in 1996 compared to $4.5 million in 1995.
The decrease was a result of lower average cash balances.  The Company  incurred
$15.2  million of  interest  expense in 1996  compared  to  $916,000 of interest
expense  in  1995   reflecting   (i)  the   discontinuation   of  interest  cost
capitalization as a result of substantially  completing the Satellite Network in

                                       F-5

<PAGE>


the fourth  quarter of 1995,  (ii) the  amortization  of debt  discount and debt
offering  costs  (including  Guarantee  Warrants  (see  "Liquidity  and  Capital
Resources")) relating to the Bridge Financing and Bank Financing (see "Liquidity
and Capital Resources"),  and (iii) higher outstanding loan balances as compared
to 1995.

Net capital  reductions,  including  additions financed through vendor financing
arrangements, for 1996 for property and equipment were $51.0 million compared to
capital  expenditures  of  $86.7  million  in 1995.  The  decrease  was  largely
attributable to (i) the net proceeds of $66.0 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 CGS were completed.


Liquidity and Capital Resources
- -------------------------------

Adequate  liquidity  and capital  are  critical to the ability of the Company to
continue  as a  going  concern  and  to  fund  subscriber  acquisition  programs
necessary  to reach cash  positive  and  profitable  operations.  To satisfy its
ongoing  financing  needs,  the Company,  on June 28, 1996,  established  a $219
million debt facility (the "Bank Financing"), of which $200 million is available
and fully guaranteed by certain American Mobile shareholders (the "Guarantors").
As of December 31, 1997,  the Bank  Financing  consisted  of: (i) a $144 million
five-year,  multi-draw  term loan  facility  (the  "Term  Loan  Facility")  with
quarterly  payments  commencing  March 31, 1999 through and  including  June 30,
2001, and (ii) a $56 million  five-year  revolving credit facility with a bullet
maturity on June 30, 2001 (the "Working  Capital  Facility").  Proceeds from the
Bank  Financing  were  used to repay  the  Company's  interim  financing  and to
refinance short-term vendor financing, and for general working capital purposes.
As previously  reported,  the Company,  on March 27, 1997,  reached an agreement
with the  Guarantors to eliminate all covenant  tests in exchange for additional
warrants and a repricing of warrants previously issued (together, the "Guarantee
Warrants").  As a result of the repricing,  the Guarantee Warrants were revalued
at $21.9  million.  As of March 20,  1998,  the  Company  had drawn down  $144.0
million of the Term Loan Facility at annual  interest  rates ranging from 6.025%
to 6.0875% and $56.0 million of the Working Capital  Facility at annual interest
rates ranging from 6.025% to 6.2125%.

As previously  mentioned (see  "Organization and Business"),  AMRC was a winning
bidder for, and on October 16, 1997,  was awarded an FCC license to provide DARS
throughout the United States.  AMRC has and will continue to receive funding for
this  business  from an  independent  source in exchange  for debt and an equity
interest in AMRC.  Accordingly,  it is not expected that the development of this
business  will have a  material  impact  on the  Company's  financial  position,
results of operations, or cash flows. The Company's equity interest in AMRC may,
however, even on a fully diluted basis, become a material asset of the Company.

In the last quarter of 1997, the Company arranged the financing of certain trade
payables,  and as of December 31, 1997, $11.7 million of deferred trade payables
were outstanding at rates ranging from 6.23% to 14% and are generally payable by
the end of 1998.

On December 4, 1997, the Company entered into two simultaneous transactions. The
Company  agreed  with TMI to  acquire a  one-half  ownership  interest  in TMI's
satellite, MSAT-1, at a cost of $60 million payable in equal installments over a
five-year  period  (the  "Satellite  Purchase  Agreement");  certain  additional
payments  to TMI are  contemplated  in the event that  additional  benefits  are
realized  by the  Company.  Under  the  Satellite  Purchase  Agreement,  TMI and
American Mobile will each own a 50% undivided  ownership  interest in the Shared
Satellite,  will  jointly  be  responsible  for  the  operation  of  the  Shared
Satellite,  and  will  share  certain  satellite  operating  expenses,  but will
otherwise maintain their separate business operations.

Simultaneously,  the Company  entered into an agreement  (the  "Satellite  Lease
Agreement") with African Continental  Telecommunications Ltd. ("ACTEL"), for the
lease of MSAT-2,  for deployment over  sub-Saharan  Africa.  The five-year lease

                                       F-6

<PAGE>


provides for  aggregate  lease  payments to the Company of $182.5  million.  The
lease includes a renewal  option  through the end of the life of MSAT-2,  on the
same lease terms, at ACTEL's  election  exercisable 2 1/2 years prior to the end
of the initial lease term.

Closing under the Satellite  Purchase Agreement and Satellite Lease Agreement is
subject  to a number  of  conditions,  including:  United  States  and  Canadian
regulatory approvals,  a successful financing by ACTEL of at least $120 million,
completion of certain  satellite  testing,  inversion and relocation  activities
with  respect to MSAT-2,  to support  the  contemplated  services  over  Africa;
receipt of various government  authorizations  from Gibraltar,  South Africa and
other jurisdictions to support satellite  relocation,  including  authorizations
with  respect to orbital  slot and  spectrum  coordination;  and  completion  of
certain  system   development   activities   sufficient  to  support   satellite
redeployment.  On March 13, 1998, the FCC provided approval of the transactions;
Canadian  government  coordination  and  approvals  remain  outstanding.  It  is
anticipated  that the closing under both the purchase and lease  agreements will
occur simultaneously in the spring of 1998.

On December 31, 1997,  the Company  entered  into a Bridge Loan  Agreement  (the
"Bridge Loan") with Hughes Communications Satellite Services, Inc. ("Hughes") in
the principal amount of up to $10 million,  secured by a pledge of the Company's
interest in its 80%-owned subsidiary,  AMRC Holdings,  Inc. The Bridge Loan bore
an annual  interest  rate of 12%,  had a maturity  date of March 31,  1999,  and
required  mandatory  repayment in the event net  proceeds are received  from any
asset  disposition,  lease  agreement,  financing or equity  transaction  of the
Company.  The Bridge Loan was drawn down in full,  and repaid on March 31, 1998,
with a portion of the proceeds of the Notes (described below).


Recent Financing Activity
- -------------------------

$335 Million Unit Offering
- --------------------------

In connection  with the  Acquisition,  the Company  issued $335 million of Units
(the  "Units")  consisting of 12 1/4% Senior Notes due 2008 (the  "Notes"),  and
Warrants to purchase  shares of Common Stock of the Company.  Each Unit consists
of $1,000  principal  amount of Notes and one Warrant to purchase 3.75749 shares
of Common Stock at an exercise  price of $12.51 per share.  A portion of the net
proceeds  of the sale of the Units were used to  finance  the  Acquisition.  The
Notes are fully guaranteed by American Mobile Satellite Corporation.


New Bank Financing
- ------------------

In connection with the Acquisition, the Company, the Acquisition Company and its
subsidiaries  restructured  the existing $200 million Bank  Financing (the "Bank
Financing") to provide for two facilities:  (i) the Revolving Credit Facility, a
$100 million unsecured  five-year reducing  revolving credit facility,  and (ii)
the Term Loan Facility, a $100 million five-year,  term loan facility with up to
three  additional  one-year  extensions  subject to the lenders'  approval.  The
Revolving  Credit  Facility  will rank pari passu with the Notes.  The Term Loan
Facility is secured by the assets of the Company,  principally its stockholdings
in AMRC and the Acquisition Company, and will be effectively subordinated to the
Revolving  Credit  Facility and the Notes.  The New Bank  Financing is severally
guaranteed   by   Hughes   Electronics   Corporation    ("Hughes"),    Singapore
Telecommunications  Ltd. ("Singapore Telecom") and Baron Capital Partners,  L.P.
(the "Bank Facility  Guarantors").  The lenders'  placement fee for the New Bank
Financing is approximately $500,000.


The Revolving Credit Facility
- -----------------------------

The Revolving  Credit  Facility bears an interest rate,  generally,  of 50 basis
points above London  Interbank  Offered Rate ("LIBOR") and is unsecured,  with a
negative  pledge on the assets of the Acquisition  Company and its  subsidiaries
ranking pari passu with the Notes. The Revolving Credit Facility will be reduced
$10 million each quarter,  beginning with the quarter ending June 30, 2002, with

                                       F-7

<PAGE>


the balance due on maturity of March 31, 2003.  Certain proceeds received by the
Acquisition  Company would be required to repay and reduce the Revolving  Credit
Facility,  unless  otherwise  waived  by  the  lenders  and  the  Bank  Facility
Guarantors:  (1) 100% of excess cash flow obtained by the  Acquisition  Company;
(2) the first $25.0 million net proceeds of the lease or sale of MSAT-2 received
by the  Acquisition  Company,  and  thereafter  75% of  the  remaining  proceeds
received  from such  lease or sale (the  remaining  25% may be  retained  by the
Acquisition  Company for business  operations);  (3) 100% of the proceeds of any
other asset sales by the Acquisition Company; (4) 50% of the net proceeds of any
offerings of the Acquisition  Company's equity (the remaining 50% to be retained
by the Acquisition Company for business  operations);  and (5) 100% of any major
casualty  proceeds.  At such time as the Revolving  Credit Facility is repaid in
full, and subject to satisfaction of the restrictive  payments provisions of the
Notes, any prepayment  amounts that would otherwise have been used to prepay the
Revolving Credit Facility will be dividended to the Company.


The Term Loan Facility
- ----------------------

The Term Loan Facility  bears an interest  rate,  generally,  of 50 basis points
above  LIBOR and is  secured  by the  assets  of the  Company,  principally  its
stockholdings in AMRC and the Acquisition  Company. The Term Loan Agreement does
not include any scheduled  amortization until maturity, but does contain certain
provisions for  prepayment  based on certain  proceeds  received by the Company,
unless otherwise waived by the Banks and the Bank Facility Guarantors:  (1) 100%
of excess cash flow  obtained by the  Company;  (2) the first $25.0  million net
proceeds of the lease or sale of MSAT-2  received by the Company, and thereafter
75% of the remaining  proceeds  received from such lease or sale (the  remaining
25% to be retained by the Acquisition Company for business operations); (3) 100%
of the  proceeds  of any other asset  sales by the  Company;  (4) 50% of the net
proceeds  of any  equity  offerings  of the  Company  (the  remaining  50% to be
retained  by the  Company for  business  operations);  and (5) 100% of any major
casualty  proceeds of the Company.  To the extent that the Term Loan Facility is
repaid, the aforementioned proceeds that would otherwise have been used to repay
the Term Loan Facility will be used to repay and reduce the commitment under the
Revolving Credit Facility.


The Guarantees
- --------------

In connection  with the New Bank  Financing,  the Bank Facility  Guarantors have
agreed  to  extend  separate  guarantees  of  the  obligations  of  each  of the
Acquisition  Company  and the  Company  to the Banks,  which on a several  basis
aggregate  to $200  million.  In their  agreement  with each of the  Acquisition
Company and the Company (the "Guarantee Issuance Agreement"),  the Bank Facility
Guarantors  have  agreed to make  their  guarantees  available  for the New Bank
Financing.  The Guarantee  Issuance  Agreement will include  certain  additional
agreements of the Acquisition  Company and of the Company including with respect
to financial  performance of the  Acquisition  Company  relating to the ratio of
debt to EBITDA and service  revenue,  which,  if not met,  could, if not waived,
limit the Acquisition Company's ability to draw down on additional amounts under
the  Revolving  Credit  Facility  and  result  in a  default  under the New Bank
Financing  beginning in 1999. In exchange for the additional risks undertaken by
the Bank  Facility  Guarantors in connection  with the New Bank  Financing,  the
Company has agreed to compensate  the Bank Facility  Guarantors,  principally in
the form of 1 million  additional  warrants  and  repricing  and  extending  the
expiration date of 5.5 million warrants  previously issued  (together,  the "New
Guarantee  Warrants").  The New  Guarantee  Warrants will be on the same pricing
terms as those issued as part of the Units.  The Bank Facility  Guarantors  will
have  certain  demand and  piggy-back  registration  rights  with  regard to the
unregistered  shares of the Company's Common Stock held by them or issuable upon
exercise of the Guarantee Warrants.

Further,  in connection with the Guarantee Issuance  Agreement,  the Company has
agreed  to  reimburse  the  Bank  Facility  Guarantors  in the  event  that  the
Guarantors  are required to make payment  under the  Revolving  Credit  Facility
guarantees,  and, in connection with this Reimbursement  Commitment has provided
the Bank  Facility  Guarantors a junior  security  interest  with respect to the
assets of the Company, principally its stockholdings in AMRC and the Acquisition
Company.


                                       F-8

Motorola Vendor Financing
- -------------------------

Motorola has agreed to provide the Acquisition  Company with up to $10.0 million
of vendor financing (the "Vendor Financing Commitment"), which will be available
to finance up to 75% of the purchase price of additional  network base stations.
Loans under this  facility will bear interest at a rate equal to LIBOR plus 7.0%
and will be  guaranteed by the Company and each  subsidiary  of the  Acquisition
Company.  The terms of such  facility  will  require  that  amounts  borrowed be
secured by the  equipment  purchased  therewith.  This  commitment is subject to
customary  conditions,  including due  diligence,  and there can be no assurance
that the facility will be obtained by the Acquisition  Company on these terms or
at all.

Summary of Recent Financing
- ---------------------------

The Company believes the proceeds from the issuance of the Notes,  together with
the borrowings under the New Bank Financing and the Vendor Financing Commitment,
will be sufficient to pay the cash portion of the Acquisition and fund operating
losses,  capital  expenditures,  working  capital,  and scheduled  principal and
interest  payments on debt through the time when the Company expects to generate
positive  free  cash flow  (operating  cash  flow  less  capital  expenditures);
however,  there  can be no  assurance  that the  Company's  current  projections
regarding the timing of its ability to achieve positive operating cash flow will
be  accurate,  and that the Company  will not need  additional  financing in the
future.  See  "Overview."  At December  31,  1997,  the  Company  had  remaining
contractual  commitments  to purchase  both mobile data  terminal  inventory and
mobile  telephone  inventory  approximating  $6.3  million.  (See Note 10 to the
consolidated financial statements).

All wholly owned subsidiaries of the Company are subject to financing agreements
that limit the amount of cash  dividends  and loans that can be  advanced to the
Company.  At  December  31,  1997,  all of these  subsidiaries'  net assets were
restricted under these  agreements.  These  restrictions  will have an impact on
American Mobile's ability to pay dividends.

Cash used in operating  activities was $50.9 million for 1997 compared to $113.6
million  for  1996.  The  decrease  in cash  used in  operating  activities  was
primarily  attributable to (i) decreased  operating  losses,  and (ii) decreased
inventory and accounts receivable  balances.  Cash used by investing  activities
was $10.2 million for 1997 compared to cash provided by investing  activities of
$50.9  million in 1996.  The $61.1  decrease was primarily  attributable  to the
proceeds in the amount of $66.0  million from the  settlement  of the  Company's
claims under its satellite insurance contracts and policies, offset by a general
reduction in capital  expenditures.  Cash provided by financing  activities  was
$61.1 million in 1997 compared to cash used of $56.0 million in 1996, reflecting
the proceeds from the Bank Financing,  offset by the repayment of certain vendor
financing and other  long-term  debt.  Proceeds from the sale of debt securities
and Common Stock were $284,000 and $2.9 million for 1997 and 1996, respectively.
Payments  on  long-term  debt and  capital  leases  were $8.8  million and $63.2
million for 1997 and 1996, respectively. In addition, the Company incurred $10.8
million  of debt  issuance  costs  associated  with  the  placement  of the Bank
Financing in 1996, as compared to $1.5 million in 1997. As of December 31, 1997,
the Company had $2.1 million of cash and cash equivalents and working capital of
$5.3 million.


Regulation
- ----------

The ownership and operations of the Company's  communication systems are subject
to significant  regulation by the FCC, which acts under authority granted by the
Communications Act of 1934, as amended (the  "Communications  Act"), and related
federal laws. A number of the  Company's  licenses are subject to renewal by the
FCC and,  with respect to the  Company's  satellite  operations,  are subject to
international  frequency  coordination.  In  addition,  current FCC  regulations
generally  limit the  ownership  and  control  of  American  Mobile by  non-U.S.
citizens  or  entities  to 25%.  There can be no  assurances  that the rules and

                                       F-9

<PAGE>


regulations  of the FCC will  continue to support the  Company's  operations  as
presently  conducted and contemplated to be conducted in the future, or that all
existing  licenses will be renewed and requisite  frequencies  coordinated.  See
"Part I, Item 1. Business - Regulation".

On June 5, 1996,  the FCC  granted  ARDIS  extensions  of time to  complete  the
buildouts  of 190 antenna  sites,  as required  to maintain  previously  granted
licenses.  As of March 25,  1998,  approximately  104 of the sites  remain to be
constructed  by  expiration  dates that range between June 27, 1998 to March 31,
1999. Management estimates that $5.2 million will be necessary to achieve timely
buildouts of the network, including $5.0 million in 1998. Failure to obtain such
capital or to complete the  buildouts in a timely manner could result in loss of
licenses  for  such  sites  from  the  FCC,  loss of  customers,  as well as the
incurrence of penalties under a customer  contract,  which would have a material
adverse effect on the Company.


Other Matters
- -------------

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. See "Part I, Item 1. Business-Satellite Back-up and Technology".

Regarding the year 2000 compliance  issue for information  systems,  the Company
has  recognized  the need to ensure that its computer  operations  and operating
systems will not be adversely affected by the upcoming calender year 2000 and is
cognizant of the time sensitive nature of the problem.  The Company has assessed
how  it  may  be  impacted  by  year  2000  and  has  formulated  and  commenced
implementation of a comprehensive plan to address known issues as they relate to
its  information  systems.  The plan,  as it  relates  to  information  systems,
includes a combination of  modification,  upgrade and  replacement.  The Company
estimates that the cost of year 2000 compliance for its information systems will
not have a material  adverse  affect on the future  consolidated  results of the
operations  of the Company.  The Company is not yet able to estimate the cost of
year 2000 compliance with respect to third party suppliers;  however, based on a
preliminary  review,  management  does not  expect  that such  costs will have a
material  adverse  effect  on the  Company's  financial  condition,  results  of
operations and cash flow.


Accounting Standards
- --------------------

In  March  1997,  the  Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards  ("SFAS") No. 128,  "Earnings  per
Share." This  Statement  governs the  calculation of Earnings per Share ("EPS"),
and requires that EPS  calculations be presented as Basic Earnings per Share and
Diluted Earnings per Share. The impact of adopting the Statement is not material
to the financial statements.

In June 1997,  the FASB issued SFAS No. 130,  "Reporting  Comprehensive  Income"
governing the reporting and display of comprehensive  income and its components,
and SFAS No.  131,  "Disclosures  about  Segments of an  Enterprise  and Related
Information"  requiring that public  businesses report financial and descriptive
information  about  its  reportable  operating  segments.  Both  Statements  are
applicable to reporting periods beginning after December 15, 1997. The impact of
adopting  the  Statements  is not  expected  to be  material  to  the  financial
statements.

   Report of Independent Public Accountants
   ----------------------------------------


To American Mobile Satellite Corporation:

We have audited the accompanying  consolidated balance sheets of American Mobile
Satellite  Corporation (a Delaware  corporation) and Subsidiaries as of December
31,  1997  and  1996,   and  the  related   consolidated   statements  of  loss,
stockholders'  equity and cash  flows for each of the three  years in the period
ended December 31, 1997. These financial  statements are the  responsibility  of
the Company's  management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards  require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosure in the financial  statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits  provide a reasonable  basis for our opinion.  In our
opinion,  the  financial  statements  referred to above present  fairly,  in all
material   respects,   the  financial  position  of  American  Mobile  Satellite
Corporation  and  Subsidiaries as of December 31, 1997 and 1996, and the results
of their  operations  and their  cash  flows for each of the three  years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

AMERICAN MOBILE SATELLITE CORPORATION AND SUBSIDIARIES
- ------------------------------------------------------

Notes to Consolidated Financial Statements
as of December 31, 1997, 1996 and 1995


1. ORGANIZATION, BUSINESS AND LIQUIDITY

American Mobile Satellite Corporation (with its subsidiaries,  "American Mobile"
or the  "Company")  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
be best served by granting the license to a consortium of all willing, qualified
applicants.  The FCC has authorized  American Mobile to construct,  launch,  and
operate a mobile satellite services system (the "Satellite Network ") 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, American Mobile Subsidiary
Corporation  ("AMSC  Subsidiary").  On April 7, 1995,  the Company  successfully
launched its first satellite ("MSAT-2"), from Cape Canaveral, Florida.

In late  1996,  the  Company  expanded  its mobile  data  business  through  the
acquisition  of  Rockwell  International  Corporation's  ("Rockwell")  dual mode
mobile  messaging and global  positioning and monitoring  service for commercial
trucking  fleets.  Rockwell was a private network  customer of the Company which
had purchased capacity from the Company on MSAT-2. See Note 12.

On December 31, 1997, the Company  entered into a Stock Purchase  Agreement (the
"Purchase Agreement") with Motorola, Inc. ("Motorola"), for the acquisition (the
"Acquisition") of ARDIS Company ("ARDIS"), a wholly-owned subsidiary of Motorola
that owns and operates a two-way wireless data communications  network.  Subject
to certain purchase price adjustment provisions,  the Company will acquire ARDIS
for a purchase  price of $50  million in cash and $50  million in the  Company's
Common Stock and  warrants  (the  "Purchase  Price").  The Company,  through the
acquisition  of ARDIS,  intends  to create a  nationwide  provider  of  wireless
communications services, including data, dispatch, and voice services, primarily
to business customers in the United States. See Note 15.

On October 16, 1997,  American Mobile Radio Corporation,  an indirect subsidiary
of American  Mobile through its subsidiary  AMRC Holdings,  Inc.  (together with
American Mobile Radio Corporation,  "AMRC"), was awarded a license by the FCC to
provide  satellite-based  Digital Audio Radio Service  ("DARS")  throughout  the
United States, following its successful $89.9 million bid at auction on April 2,
1997.  American  Mobile has entered  into an  agreement  with  WorldSpace,  Inc.
("WorldSpace"),  by which  WorldSpace has acquired a 20%  participation in AMRC,
which can dilute the Company's  interest in AMRC to 28%. In connection  with the
DARS  auction,  AMRC has also  arranged for financing of the FCC license fees as
well as for initial  working  capital  needs,  which  financing has included the
issuance of  options.  AMRC has and will  continue  to receive  funding for this
business from an independent  source in exchange for debt and an equity interest
in AMRC.  Accordingly,  it is not expected that the development of this business
will have a material  impact on the  Company's  financial  position,  results of
operations, or cash flows. See Note 2.

American Mobile is devoting its efforts to expanding a developing business. This
effort involves  substantial risk,  including  successfully  integrating  ARDIS.
Specifically,  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.


Liquidity and Financing Requirements
- ------------------------------------

Adequate  liquidity  and capital  are  critical to the ability of the Company to
continue  as a  going  concern  and  to  fund  subscriber  acquisition  programs
necessary to reach cash positive and profitable operations.  The Company expects


                                      F-16

<PAGE>



to continue to make  significant  capital outlays for the foreseeable  future to
fund interest  expense,  capital  expenditures  and working capital prior to the
time that it begins to generate  positive cash flow from  operations and for the
foreseeable future thereafter.  To fund its operations through the first quarter
of 1998, the Company (i) borrowed all remaining amounts available under the Bank
Financing,  (ii) entered into a $10 million  Bridge Loan  Agreement (the "Bridge
Loan") with Hughes Communications Satellite Services, Inc. ("Hughes"), and (iii)
arranged the financing of $11.7 million of deferred trade payables. See Note 7.

The Company  currently  believes that the net proceeds from the sale of the $335
million  in Notes and  warrants,  together  with the  borrowings  under the $200
million New Bank Financing (as defined herein), the Motorola financing,  and the
proceeds  from the  Satellite  Lease  Agreement  (all  discussed  below) will be
sufficient to meet the Company's  currently  anticipated  capital  expenditures,
operating losses, working capital and debt service requirements through 1998 and
beyond.  However,  if the  Company's  cash flows from  operations  are less than
projected,  the Company may not meet its financial performance  agreements under
the Guaranty  Issuance  Agreement and, if such conditions are not met or waived,
the Company would not have access to additional funds under the Revolving Credit
Facility.  See Note 15. In  addition,  even in the event  that the  Company  has
access to such funds,  it may require  additional  debt or equity  financing  in
amounts  that could be  substantial.  The type,  timing  and terms of  financing
selected by the Company will be dependent  upon the  Company's  cash needs,  the
availability  of other  financing  sources and the prevailing  conditions in the
financial  markets.  There can be no  assurance  that any such  sources  will be
available  to the  Company at any given time or as to the  favorableness  of the
terms on which such sources may be available.

In connection  with the ARDIS  Acquisition,  the Company  raised $335 million in
cash proceeds from the private issuance of units ("Units") consisting of 12 1/4%
Senior Notes  ("Notes") due 2008 and one warrant to purchase  3.75749  shares of
Common  Stock of the  Company  for each $1,000  principal  amount of Notes,  and
restructured  its existing Bank  Financing (the "New Bank  Financing").  The New
Bank  Financing  of  $200  million  will  consist  of a $100  million  unsecured
five-year  reducing Revolving Credit Facility maturing March 31, 2003 and a $100
million  five-year  Term  Loan  Facility  with up to three  additional  one-year
extensions  subject to lender  approval.  Additionally,  Motorola  has agreed to
provide the  Company  with up to $10 million of vendor  financing  (the  "Vendor
Financing  Commitment"),  which  will be  available  to finance up to 75% of the
purchase  price of  additional  base  stations  needed to meet  ARDIS'  buildout
requirements under certain customer contracts. See Note 15.

On December 4, 1997, the Company entered into two simultaneous transactions. The
Company  agreed  with TMI to  acquire a  one-half  ownership  interest  in TMI's
satellite, MSAT-1, at a cost of $60 million payable in equal installments over a
five-year  period  (the  "Satellite  Purchase  Agreement");  certain  additional
payments  to TMI are  contemplated  in the event that  additional  benefits  are
realized by the Company.  Simultaneously,  the Company entered into an agreement
(the "Satellite Lease  Agreement") with African  Continental  Telecommunications
Ltd.  ("ACTEL"),  for the  lease of MSAT- 2,  for  deployment  over  sub-Saharan
Africa. The five-year lease provides for aggregate lease payments to the Company
of $182.5  million.  The lease  includes a renewal option through the end of the
life of MSAT-2.  Closing  under the Satellite  Purchase  Agreement and Satellite
Lease Agreement is subject to a number of conditions. It is anticipated that the
closing under both leasing agreements will occur simultaneously in the spring of
1998. See Note 10.


2. SIGNIFICANT ACCOUNTING POLICIES

Development Stage Company
- -------------------------

Consistent  with  Statement of Financial  Accounting  Standards  ("SFAS") No. 7,
"Accounting and Reporting by Development Stage  Enterprises," the Company ceased
to be considered a development  stage company in the fourth quarter of 1996 with
the generation of significant revenue from its voice products and services.


Accounting Estimates
- --------------------

The preparation of financial  statements in conformity  with generally  accepted
accounting   principles  (GAAP)  requires   management  to  make  estimates  and
assumptions  that affect the reported  amount of assets and  liabilities  at the
date of the  financial  statements  and the  reported  amounts of  revenues  and


                                      F-17

<PAGE>


expenses  during the reporting  period.  Actual  results could differ from those
estimates.  The Company's most significant  estimates relate to the valuation of
inventory  and  committed  inventory  purchases  and the  allowance for doubtful
accounts receivable.


Consolidation
- -------------

The consolidated  financial  statements  include the accounts of American Mobile
and  seven of its  wholly  owned  subsidiaries,  one of which is  inactive.  All
significant  inter-company  transactions and accounts have been  eliminated.  As
discussed in Note 1, AMRC was awarded a license to provide  digital  audio radio
service  ("DARS") and entered into an  agreement  with World Space, Inc. ("World
Space"),  whereby World Space has acquired a 20%  participation in AMRC, and the
exercise of outstanding  issued options could reduce American Mobile's ownership
interest in AMRC to 28%.  Additionally,  the agreement gives WorldSpace  certain
participative  rights  which  provide  for their  participation  in  significant
business  decisions  that  would be made in the  ordinary  course  of  business;
therefore, in accordance with Emerging Issues Task Force ("EITF") No. 96-16, the
Company's investment in AMRC is carried on the equity method.

The following represents the unaudited summary financial  information of AMRC as
of December 31,1997. AMRC had no material activity prior to 1997.

</TABLE>


Cash and Cash Equivalents
- -------------------------

The Company considers highly liquid investments with remaining  maturities of 90
days or less at the time of acquisition to be cash equivalents.


Inventories
- -----------

Inventories,  which consist primarily of finished goods, are stated at the lower
of cost or market.  Cost is determined  using the weighted  average cost method.
The Company  periodically  assesses the market value of its inventory,  based on
sales trends and  forecasts  and  technological  changes and records a charge to
current  period  income  when such  factors  indicate  that a  reduction  to net
realizable  value is appropriate.  For purposes of evaluating the net realizable
value of inventory,  management  considers  both inventory on hand and inventory
which it has committed to purchase.  During 1997 and 1996, the Company  recorded
charges  to Cost of  Equipment  Sold in the  amount of $12.0  million  and $11.1
million,  respectively,  related to the realizability of the Company's inventory
investment.


Fair Value of Financial Instruments
- -----------------------------------

SFAS No. 107, "Disclosures about Fair Value of Financial  Instruments," requires
disclosures of the fair value of certain financial instruments.  For purposes of
this disclosure, the fair value of a financial instrument is the amount at which
the  instrument  could be exchanged  in a current  transaction  between  willing
parties.  Cash and cash  equivalents,  trade  accounts  receivable  and accounts
payable approximate fair value because of the relatively short maturity of these
instruments. As a result of the Guarantees (see Note 7) associated with the Bank
Financing,  it is not  practicable  to estimate the fair value of this facility.
The fair value of other debt  approximates  carrying  value  because the related
debt has variable interest costs based on current market rates or are short-term
in nature.




                                      F-18

<PAGE>



Concentrations of Credit Risk
- -----------------------------

Financial instruments which potentially subject the Company to concentrations of
credit risk  consist  principally  of  temporary  cash  investments,  short-term
investments  and accounts  receivable.  The Company  places its  temporary  cash
investments  and short-term  investments in debt  securities  such as commercial
paper,  time  deposits,   certificates  of  deposit,  bankers  acceptances,  and
marketable  direct  obligations  of the United  States  Treasury.  The Company's
intent is to hold its investments in debt  securities to maturity.  To date, the
majority of the Company's business has been transacted with  telecommunications,
natural resources and transportation companies,  including maritime and trucking
companies located  throughout the United States. The Company grants credit based
on an  evaluation  of the  customer's  financial  condition,  generally  without
requiring  collateral  or  deposits.   Exposure  to  losses  on  trade  accounts
receivable,  for both service and for inventory sales, is principally  dependent
on each customer's financial condition.  The Company anticipates that its credit
risk with respect to trade accounts receivable in the future will continue to be
diversified  due to the large  number of  customers  expected  to  comprise  the
Company's base and their expected  dispersion  across many different  industries
and geographies.


Software Development Costs
- --------------------------

The Company  capitalizes costs related to the development of certain software to
be used with its mobile  messaging  and position  location  service (the "Mobile
Data  Communications  Service") product.  The Company commenced  amortization of
these costs in the first  quarter of 1996.  These costs will be  amortized  over
three  years.  As of  December  31,  1997 and  1996,  net  capitalized  software
development  costs were $1.8  million and $3.6  million,  respectively,  and are
included in property and equipment in the accompanying balance sheets.


Deferred Charges and Other Assets
- ---------------------------------

Other assets  primarily  consist of unamortized  financing  costs and debt issue
costs  associated with the existing vendor  financing  arrangements and the Bank
Financing.  The  Company  had $11.8  million  and $14.9  million of  unamortized
financing costs recorded at December 31, 1997 and 1996, respectively.  Financing
costs are  amortized  over the term of the related  facility  using the straight
line method, which approximates the effective interest method.


Revenue Recognition
- -------------------

The Company  recognizes service revenue when  communications  services have been
rendered.  Equipment sales are recognized upon shipment of products and customer
acceptance, if required.


Research and Development Costs
- ------------------------------

Research and  development  costs are expensed as  incurred.  Such costs  include
internal  research  and  development  activities  and expenses  associated  with
external product development agreements.  The Company did not incur any research
and  development  cost for 1997,  and  incurred  approximately  $57,000 and $1.8
million for 1996 and 1995, respectively.


Advertising Costs
- -----------------

Advertising  costs are charged to  operations  in the year  incurred and totaled
$3.4  million,  $6.0  million,  and  $6.5  million  for  1997,  1996,  and  1995
respectively.



                                      F-19

<PAGE>



Stock Based Compensation
- ------------------------

The Company  accounts for employee  stock options using the method of accounting
prescribed by APB Opinion No. 25,  "Accounting  for Stock Issued to  Employees."
Generally,  no expense is  recognized  related to the  Company's  stock  options
because the option's  exercise  price is set at the stock's fair market value on
the date the option is granted.  Effective  January 1, 1996, the Company adopted
SFAS No. 123 by making the required footnote disclosures (see Note 5).


Assessment of Asset Impairment
- ------------------------------

SFAS No.  121  "Accounting  for the  Impairment  of  Long-Lived  Assets  and for
Long-Lived  Assets to be Disposed of" requires that  impairment  losses for such
assets  be based  upon the fair  value of the  assets,  and was  adopted  by the
Company as the primary  basis by which the Company  measures  impairment  of the
Satellite Network and its related components. Adoption of this Statement has not
resulted in the  recording of a provision for  impairment of long-lived  assets,
but there can be no assurance that a material  provision for impairment will not
be required in the future.


Loss Per Share
- --------------

In 1997,  the Company  adopted SFAS No. 128,  "Earnings Per Share." SFAS No. 128
requires dual  presentation of basic and diluted  earnings per share on the face
of the income  statement  for all periods  presented.  Basic  earnings per share
excludes  dilution  and 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 issued common stock were exercised or
converted into common stock.  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.



3. STOCKHOLDERS' EQUITY

The Company has  authorized  200,000  shares of Preferred  Stock and  75,000,000
shares of  Common  Stock.  The par  value  per share is $0.01 for each  class of
stock.  For each share held,  Common  stockholders  are  entitled to one vote on
matters  submitted  to the  stockholders.  Cumulative  voting  applies  for  all
elections of directors of the Company.

The Preferred Stock may be issued in one or more series at the discretion of the
Board of Directors (the "Board"),  without  stockholder  approval.  The Board is
authorized   to  determine   the  number  of  shares  in  each  series  and  all
designations, rights, preferences, and limitations on the shares in each series,
including,  but not limited to, determining whether dividends will be cumulative
or non-cumulative.

Certain   controlling   stockholders   of  the  Company   have  entered  into  a
Stockholders'  Agreement (the "Agreement") which contains provisions relating to
the election of directors,  procedures for maintaining compliance with the FCC's
alien ownership  restrictions,  certain  restrictions on the transfer,  sale and
exchange  of Common  Stock,  and  procedures  for  appointing  directors  to the
Executive  Committee of the Board,  among  others.  The  Agreement  continues in
effect until  terminated by an affirmative  vote of holders of  three-fourths of
the  Company's  Common  Stock held by parties to the  Agreement.  Other  matters
relating  to the  Company's  governance  of the  Company  are set  forth  in the
Certificate of Incorporation and Bylaws.

As of  December  31,  1997,  the Company had  reserved  Common  Stock for future

4. PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost and depreciated  over its useful life
using the straight line method.  Assets recorded as capital leases are amortized
over the shorter of their useful lives or the term of the lease.  The  estimated
useful lives of office  furniture  and equipment  vary from 2-10 years,  and the
Communications Ground Segment ("CGS") is depreciated over 8 years.

The Company is depreciating  the Space Segment over its estimated useful life of
10 years,  which was based on several factors,  including current conditions and
the estimated  remaining fuel of MSAT-2.  The original  estimated useful live is
periodically  reviewed  using current  Telemetry  Tracking and Control  ("TT&C")
data. To date, no significant  change in the original  estimated useful life has
resulted.  The  telecommunications  industry  is subject to rapid  technological
change  which may require the Company to revise the  estimated  useful  lives of
MSAT-2 and the CGS or to adjust  their  carrying  amounts.  The Company has also
capitalized  certain  costs to develop and implement  its  computerized  billing
system.  These costs are included in property and equipment and are  depreciated
over 8 years. Certain amounts from 1996 have been restated in the summary below.

The costs of constructing and putting satellites into service are capitalized in
the financial  statements and depreciated  over the estimated useful life of the
satellite. A total failure of the satellite from unsuccessful launches and/or in
orbit  anomalies  would result in a current  write-down of the satellite  value.
Partial  satellite  failures are recognized  currently to the extent such losses
are deemed  abnormal to the operation of the satellite.  A partial failure which
is deemed normal would not result in a loss of satellite capacity beyond what is
considered  normal  satellite  wear and tear and thus, a write down would not be
required.  Additionally,  all  future  incentive  arrangements  relating  to the
construction of satellites will be capitalized at launch.

5. STOCK OPTIONS

The Company has two active stock option  plans.  The American  Mobile  Satellite
Corporation  1989 Amended and  Restated  Stock  Option Plan for  Employees  (the
"Plan") permits the grant of non-statutory options and the award of  bonus stock

                                      F-21

<PAGE>



up to a total of 3.5  million  shares of  Common  Stock.  Under  the  Plan,  the
exercise   price  and  vesting   schedule  for  options  is  determined  by  the
Compensation  Committee of the Board,  which was  established  to administer the
Plan. Generally, options vest over a three year period and will have an exercise
price not less than the fair  market  value of a share on the date the option is
granted  or have a term  greater  than ten years.  In March  1997,  the  Company
repriced  certain  employee stock options to $13.00 per share. No other terms of
the options were modified.

The  Company  also has a Stock  Option  Plan  for  Non-Employee  Directors  (the
"Director Plan") which provides for the grant of options up to a total of 50,000
shares of Common Stock.  Directors  receive an initial  option to purchase 1,000
shares of Common  Stock,  with annual  option  grants to purchase  500 shares of
Common Stock.  Options under the Director Plan can be exercised at a price equal
to the fair  market  value of the  stock on the date of the  grant and are fully
vested and  immediately  exercisable  on the date of grant.  Each  Director Plan
option  expires  on the  earlier of (i) ten years from the date of grant or (ii)
seven months after the Director's termination.

In January 1998,  the Board of Directors  granted  356,111  shares of restricted
stock to senior  management  for the first time.  These  grants  include  both a
three-year vesting schedule as well as specific corporate  performance  targets.
Unless waived by the Board of Directors,  failure to meet a required performance
target would prevent the vesting of the restricted shares.

6. INCOME TAXES

The Company  accounts for income taxes under the liability method as required in
the Statement of Financial  Accounting Standards No. 109, "Accounting for Income
Taxes." Under the liability method, deferred income taxes are recognized for the
tax consequences of "temporary  differences" by applying  enacted  statutory tax
laws and rates  applicable to future years to differences  between the financial
statement carrying amounts and the tax bases of existing assets and liabilities.
Under  this  method,  the effect on  deferred  taxes of a change in tax rates is
recognized in income in the period that includes the enactment  date.  Potential
tax benefits,  related to net operating losses and temporary  differences,  have
been  recorded as an asset,  and a valuation  allowance  for the same amount has
been established. The Company has paid no income taxes since inception.

The following is a summary of the Company's net deferred tax assets.

Significant  timing  differences  affecting  deferred  taxes  in 1997  were  the
treatment of costs  associated  with the Space Segment for  financial  reporting
purposes compared to tax purposes.  As of December 31, 1997, the Company had net
operating loss carryforwards  ("NOLs") of $542 million. The NOLs expire in years
2004 through 2012. These NOL carryforwards are subject to certain limitations if
there is determined  to be a  substantial  change in ownership as defined in the
Internal Revenue Code.

Bank Financing- Term Loan and Working Capital Facility
- ------------------------------------------------------

On June 28, 1996,  the Company  established  a $219 million debt  facility  (the
"Bank  Financing"),  of which $200 million is available and fully  guaranteed by
certain  American  Mobile  shareholders.  As of  December  31,  1997,  the  Bank
Financing  consisted  of: (i) a $144  million  five-year,  multi-draw  term loan
facility (the "Term Loan Facility") with quarterly payments commencing March 31,
1999  through and  including  June 30,  2001,  and (ii) a $56 million  five-year
revolving  credit facility with a bullet maturity on June 30, 2001 (the "Working
Capital  Facility").  Proceeds  from the Bank  Financing  were used to repay the
Company's  interim financing and to refinance  short-term Vendor Financing,  and
will be used for general  working  capital  purposes.  As of March 20, 1998, the
Company  had drawn  down  $144.0  million  of the Term Loan  Facility  at annual
interest  rates  ranging from 6.025% to 6.0875% and $56.0 million of the Working
Capital  Facility at annual  interest rates ranging from 6.025% to 6.2125%.  The
Company,  on March  27,  1997,  reached  an  agreement  with the  Guarantors  to
eliminate all covenant tests in exchange for additional warrants and a repricing
of warrants previously issued (together, the "Guarantee Warrants").  As a result
of the  repricing,  the  Guarantee  Warrants  were  revalued  at $21.9  million,
effective  March 27,1997 and are being  amortized over the remaining life of the
guarantee.  On March 31, 1998,  in  connection  with the  Acquisition,  the Bank
Financing was restructured. See Note 15.


Deferred Trade Payables
- -----------------------

In the last quarter of 1997, the Company arranged the financing of certain trade
payables. As of December 31, 1997, $11.7 million of deferred trade payables were
outstanding at rates ranging from 6.23% to 14% and are generally  payable by the
end of 1998.


Bridge Loan
- -----------

On  December  31,  1997,  the  Company  entered  into a Bridge  Loan with Hughes
Communications Satellite Services, Inc. ("Hughes") in the principal amount of up
to $10 million,  secured by a pledge of the Company's  interest in its 80%-owned
subsidiary, AMRC. The Bridge Loan bears an annual interest rate of 12% and has a
maturity date of March 31, 1999, and requires  mandatory  repayment in the event
net proceeds are received from any asset disposition, lease agreement, financing
or equity  transaction  of the  Company.  The Bridge  Loan was drawn in full and
subsequently  repaid in full on March 31,  1998,  with a portion of the proceeds
from the Notes. No further borrowing is available under the Bridge Loan.
See Note15.


Term Loan Agreement
- -------------------

The Company  entered  into a Term Loan  Agreement  (the "Loan  Agreement")  with
Northern Telecom to finance the purchase of certain  equipment to be used in the
ground segment.  The Loan Agreement provided for principal borrowings up to $7.5
million plus $1.1 million for accrued  interest.  In September 1996, the Company


                                      F-24

<PAGE>


arranged to reduce the interest  rate from LIBOR plus 4.5% to a floating rate of
LIBOR  plus  2.5%  through  maturity  and to defer  amounts  due  under the Loan
Agreement  to1997.  In December 1997, the Loan Agreement was amended to increase
the interest rate to LIBOR plus 4.5%,  effective January 1, 1998, and to defer a
portion of principal payments until April 1, 1998. As of December 31, 1997, $4.9
million was outstanding at an annual interest rate of 8.156%.


Deferred Payment Agreement
- --------------------------

In 1992, the Company entered into a contract ("CGS Contract") with  Westinghouse
Electric  Corporation   ("Westinghouse")  pursuant  to  which  Westinghouse  was
responsible for designing and constructing the Ground Segment and developing the
final specification for mobile telephones.  In connection with the CGS Contract,
Westinghouse agreed to defer payment,  including interest thereon, under certain
terms and  conditions,  for the basic  purchase  price and for change orders and
options elected by the Company (the "Deferred Payment Agreement").  During 1997,
the remaining $5.2 million  obligation under the Deferred Payment  Agreement was
fully repaid.


Interest Costs
- --------------

The Company  incurred  interest  costs of  approximately  $21.6  million,  $15.1
million,  and $5.6 million in 1997, 1996, and 1995,  respectively.  All interest
costs  incurred  through  September  30,  1995 were  capitalized  as part of the
Company's   construction   activities.   The   capitalization  of  interest  was
discontinued in the fourth quarter of 1995 when the Satellite Network was deemed
substantially  complete and ready for its intended use.  Interest cost paid, net
of amounts capitalized, was $ 327,000 in 1995.


Assets Pledged and Secured
- --------------------------

All wholly owned subsidiaries of the Company are subject to financing agreements
that limit the amount of cash  dividends  and loans that can be  advanced to the
Company.  At  December  31,  1997,  all of the  subsidiaries'  net  assets  were
restricted under these  agreements.  These  restrictions  will have an impact on
American Mobile Satellite Corporation's ability to pay dividends.


Covenants
- ---------

The debt agreements and related Guarantee Agreements entered into by the Company
contain various restrictions,  covenants, defaults, and requirements customarily
found in such financing agreements.  Among other restrictions,  these provisions
include  limitations on cash dividends,  restrictions  on  transactions  between
American  Mobile and its  subsidiaries,  restrictions  on capital  acquisitions,
material  adverse  change  clauses,   and  maintenance  of  specified  insurance
policies.


8. RELATED PARTIES

In 1990,  following a competitive bid process,  American Mobile signed contracts
with Hughes  Aircraft,  the parent  company of Hughes  Communications  Satellite
Services ("Hughes Communications"), an American Mobile stockholder, to construct
MSAT-2 (the "Satellite  Construction  Contract").  The contract  contains flight
performance  incentives  payable  by the  Company to Hughes  Aircraft  if MSAT-2
performs according to the contract.  The total incentives owed, if earned,  will
be $7.1 million,  plus  interest,  with payment  amounts  otherwise due deferred
until second quarter 1998.  The costs of the  incentives are  capitalized in the
period  earned.  The Company  also in 1990  selected  HNS Ltd.,  an affiliate of
Hughes Aircraft, to design, manufacture, and implement the Company's Mobile Data
Communications  Service.  In 1991,  the Company  entered into an agreement  with
Hughes  Communications to provide assistance in the launch services  procurement
process  and  certain  other  management   services  through  the  launch  date.
Additionally,  in 1996,  Hughes  loaned the Company $10.0 million as part of its
participation in  the Interim Financing.  On  December  31,  1997,  the  Company

                                      F-25

entered  into  a  Bridge  Loan   Agreement   (the  "Bridge  Loan")  with  Hughes
Communications in the principal amount of up to $10 million (see Note 7).

The Company has entered into various transactions and agreements with affiliates
of  AT&T  Wireless  Services,   Inc.  ("AT&T  Wireless"),   an  American  Mobile
stockholder.  The  arrangements  include the purchase of satellite  capacity and
equipment by AT&T, the purchase by American Mobile of certain  equipment for use
in the  Satellite  Network,  the leasing of certain  office  equipment,  and the
engagement  of  AT&T  to  be  one  of  the  Company's  long-distance  providers.
Additionally,  the Company sublet certain office space to AT&T Wireless  through
September  1996.  The  following  table  presents  a summary  of  related  party
transactions.

In January 1996, the Company  refinanced  certain computer  hardware  components
under a sale/leaseback arrangement.  The Company received proceeds in the amount
of $1.7 million.  The transaction was accounted for as a financing,  wherein the
property  remains on the books and  continues  to be  depreciated.  A  financing
obligation  representing  the proceeds  was  recorded,  and is reduced  based on
payments under the lease.  The  sale/leaseback  has a three-year  term and had a
balance of approximately $93,000 at December 31, 1997.


Operating Leases

The Company leases certain facilities and equipment under arrangements accounted
for as operating leases.  Certain of these  arrangements have renewal terms. The
office lease has an original  lease term of ten years  expiring in 2003,  with a
renewal option, and escalation clauses.  Total rent expense, under all operating
leases,  approximated  $2.9 million,  $2.5  million,  and $10.6 million in 1997,
1996, and 1995, respectively.

At December  31,  1997,  minimum  future  lease  payments  under  noncancellable
operating and capital leases are as follows:

10. OPERATING AGREEMENTS AND COMMITMENTS

Joint Operating and Satellite Capacity Agreements
- -------------------------------------------------

On December 4, 1997, the Company entered into two simultaneous transactions. The
Company  agreed  with TMI to  acquire a  one-half  ownership  interest  in TMI's
satellite, MSAT-1, at a cost of $60 million payable in equal installments over a
five-year  period  (the  "Satellite  Purchase  Agreement");  certain  additional
payments  to TMI are  contemplated  in the event that  additional  benefits  are
realized  by the  Company.  Under  the  Satellite  Purchase  Agreement,  TMI and
American Mobile will each own a 50% undivided  ownership  interest in the Shared
Satellite,  will  jointly  be  responsible  for  the  operation  of  the  Shared
Satellite,  and  will  share  certain  satellite  operating  expenses,  but will
otherwise  maintain  their separate  business  operations.  Simultaneously,  the
Company entered into an agreement (the "Satellite Lease Agreement") with African
Continental  Telecommunications  Ltd.  ("ACTEL"),  for the lease of MSAT-2,  for
deployment over sub-Saharan  Africa.  The five-year lease provides for aggregate
lease  payments to the Company of $182.5  million.  The lease includes a renewal
option  through  the end of the life of  MSAT-2,  on the same  lease  terms,  at
ACTEL's  election  exercisable 2 1/2 years prior to the end of the initial lease
term.

Should the Satellite  Purchase  Agreement and Satellite  Lease  Agreement not be
consummated,  the  Company  and TMI will  remain  parties  to a Joint  Operating
Agreement and a Satellite  Capacity  Agreement  under which the parties agree to
provide,  among other  things,  emergency  backup and restoral  services to each


                                      F-27

<PAGE>


party  during  any  period in which the  other's  satellite  is not  functioning
properly.  Additionally,  each party will be entitled to lease  excess  capacity
from the other party's  satellite  under  specified  terms and  conditions.  The
implementation of these agreements requires regulatory  approvals by the FCC and
Industry  Canada  (formerly  Canada's  Department of Industry and Science).  The
Company has  received,  and expects to continue to seek  approvals  contemplated
under these agreements on a timely basis.


Commitments
- -----------

At December 31,  1997,  the Company had  remaining  contractual  commitments  to
purchase both mobile data  terminal  inventory  and mobile  telephone  inventory
approximating $6.3 million.

The aggregate fixed and  determinable  portion of all inventory  commitments and
obligations for other fixed contracts for the next five years is as follows.


(in thousands)

1998                           $7,011
1999                            1,802
2000                              426
                               ------
Total                          $9,239
                               ======

Additionally, the Company may enter into additional commitments that may require
the purchase of mobile  telephone and mobile terminal  inventory in amounts that
could be material to the Company's financial condition.

The Company entered an agreement with a vendor,  whereby the Company would incur
extra licensing fees, up to a total maximum potential of $4.1 million,  upon the
voice subscriber base reaching certain levels.  Management does not believe that
the subscriber levels outlined in the license will be met.



11. EMPLOYEE BENEFITS

Defined Contribution Plan
- -------------------------

The Company sponsors a 401(k) defined  contribution plan ("401(k) Savings Plan")
in which all employees can  participate.  Effective  January 1, 1995, the 401(k)
Savings Plan provides for a Company match of employee contributions, in the form
of Common  Stock,  limited to the fair  market  value of up to  one-half  of the
employee's  contribution not to exceed 6% of an employee's salary. The Company's
matching expense was $350,000 for 1997, $411,000 for 1996 and $329,000 for 1995.


Employee Stock Purchase Plan
- ----------------------------

In December 1993,  the Company  adopted the Employee Stock Purchase Plan ("Stock
Purchase Plan") to allow eligible  employees to purchase shares of the Company's
Common Stock at 85% of the lower of market value on the first and last  business
day of the six-month  option period.  An aggregate of 29,930,  39,366 and 30,877
shares of Common Stock were issued under the Stock Purchase Plan in 1997,  1996,
and 1995, respectively.



12.  BUSINESS ACQUISITION

On November 22, 1996, the Company acquired the assets of Rockwell Collins,  Inc.
("Rockwell")   relating   to  its   Land   Transportation   Electronics   Mobile
Communications   Satellite  Service  business  (the  "Business")  through  which
Rockwell had sold mobile messaging hardware and services to commercial  trucking
fleets.  The assets of the Business  were  acquired  from  Rockwell  through the
assumption by the Company of the various  contracts and  obligations of Rockwell


                                      F-28

<PAGE>


relating to the Business;  no additional  direct payments were made or are to be
made under the terms of the Asset Sale Agreement, dated as of November 22, 1996.
The assets of the business  acquired from Rockwell include  tangible  equipment,
completed  inventory  and future  inventory  deliveries to be used in connection
with fulfilling the contracts transferred with the Business. The Company intends
to continue such use in operating the Business.

The purchase  method of  accounting  for  business  combinations  was used.  The
operating   results  of  the  Business  have  been  included  in  the  Company's
consolidated   statements  of  loss  from  the  date  of  acquisition  and  were
insignificant  in 1996.  The fair value of the assets  acquired was $9.5 million
and liabilities assumed totaled $6.1 million.  The fair value of assets acquired
in excess of purchase  price arising from the  acquisition in the amount of $3.4
million is being  amortized  over five years on a straight  line  basis.  Assets
acquired included inventory  deliveries,  fixed assets, and other  miscellaneous
items.

The pro forma results below (unaudited)  assume the acquisition  occurred at the
beginning of the year ended December 31, 1996 (dollars in thousands,  except per
share data).

13. LEGAL AND REGULATORY AND OTHER MATTERS

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  successful  operation of the Satellite  Network 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
cash flows.

The Company has the necessary regulatory  approvals,  some of which are pursuant
to  special  temporary  authority,  to  continue  its  operations  as  currently
contemplated.  The  Company has filed  applications  with the FCC and expects to
file applications in the future with respect to the continued operations, change
in  operation  and  expansion  of the Network and  certain  types of  subscriber
equipment.  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,  will be granted on a timely basis or 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 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


                                      F-29

<PAGE>


the second and third  satellites and in connection  with 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.

As a provider of interstate telecommunications services, the Company is required
to contribute to the FCC's universal  service fund, which supports the provision
of  telecommunication  services to  high-cost  areas,  and  establishes  funding
mechanisms  to support the provision of service to schools,  libraries and rural
health care providers.  The regulation became effective on January 1, 1998. This
cost  is not  born by the  Company,  but is  passed  on to its  customers  as is
universally practiced in the industry.

In 1992, a former director of American Mobile 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  judgment,  filed on
March  31,  1994,  was  denied  on April 18,  1996.  The  trial in this  matter,
previously  set for December 1997, has been postponed to a date to be determined
in 1998.  Management  believes that the ultimate outcome of this matter will not
be material to the Company's financial  position,  results of operations or cash
flows.


Other Matters
- -------------

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.  Based on certain
engineering  studies and the design of the satellite,  the Company believes that
the  insurance  proceeds  reflected  the actual cost of damage  sustained to the
satellite,  and, as a result, the carrying value of the satellite was reduced by
the net insurance proceeds, which resulted 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.

The Company has received a current  recommendation  from a subcontractor  to its
satellite   manufacturer   that,   pending   further  results  from  an  ongoing
investigation,  the satellite  should be operated at modified  power  management
levels. The Company and its satellite  manufacturer are investigating the basis,
if any, for this  recommendation.  Based on the  information  available to date,
management  believes  that,  even if  maintained,  the current power  management
recommendation  would  not have a  material  negative  effect  on the  Company's
business plan within the next three to five years, based on anticipated  traffic
patterns and anticipated  subscriber  levels. In the event that traffic patterns
or subscriber levels materially exceed those  anticipated,  the power management
recommendation,  if  maintained,  could have a material  impact on the Company's
long-term business plan.

NOTE 15 - SUBSEQUENT EVENTS

During  the  first  quarter  of 1998,  the  Company  entered  into a  series  of
transactions. These transactions, some of which contain certain contingencies to
closing,  include the  acquisition of ARDIS and related $335 million  financing;
the restructuring of the Bank Financing; and a commitment by Motorola to provide
the Company with up to $10 million of vendor financing  related to the build out
of the ARDIS network.


Stock Purchase Agreement and Related Financing
- ----------------------------------------------

As discussed in Note 1, on December 31, 1997,  the Company  entered into a Stock
Purchase  Agreement  with  Motorola  for the  acquisition  of ARDIS,  a Motorola
subsidiary  that  owns and  operates  a  two-way  wireless  data  communications
network.   Subject  to  certain   post-acquisition   purchase  price   reduction
provisions,  the Company would acquire ARDIS for a purchase price of $50 million
in cash and $50 million in the Company's stock and warrants. The transaction was
subject to certain governmental  approvals,  including FCC approvals to transfer
the ARDIS  licenses  to the  Company,  and was  subject to the  completion  of a
financing  by the  Company  in an  amount  sufficient  to fund the  transactions
contemplated  under the Stock  Purchase  Agreement.  On March 3,  1998,  the FCC
granted  consent to  consummate  the  Acquisition,  and on March 31,  1998,  the
Acquisition was consummated.


$335 Million Unit Offering
- --------------------------

In  connection  with the  Acquisition,  the  Company  formed a new  wholly-owned
subsidiary ("Acquisition Company") to hold the stock of all current wholly-owned
operating  subsidiaries,   acquire  ARDIS,  and  issue  $335  million  of  Units
consisting of 12 1/4% Senior Notes due 2008 of Acquisition Company, and Warrants
to purchase shares of Common Stock of the Company.  Each Unit consists of $1,000
principal  amount of Notes and one Warrant to purchase  3.75749 shares of Common
Stock at an exercise price of $12.51 per share. A portion of the net proceeds of
the sale of the Units were used to finance the Acquisition.  The Notes are fully
guaranteed  by American  Mobile  Satellite  Corporation.  The terms of the Notes
require  that the Company  purchase a portfolio  of U.S.  government  securities
(approximately $113 million), which will provide funds sufficient to pay in full
when due the first six scheduled semi-annual interest payments on the Notes. The
Company  intends to use the  remaining  proceeds  from the Notes to fund certain
required escrows, repay the Bridge Loan, repay certain deferred obligations, pay
expenses associated with the Acquisition and the $335 Million Unit Offering,  to
repay the Revolving  Credit Facility under the Bank  Financing,  and for working
capital requirements.


New Bank Financing
- ------------------

In connection with the Acquisition, the Company, the Acquisition Company and its
subsidiaries  restructured  the existing $200 million Bank  Financing to provide
for the New Bank Financing:  (i) the Revolving Credit  Facility,  a $100 million
unsecured  five-year reducing revolving credit facility,  and (ii) the Term Loan
Facility,  a $100  million  five-year,  term  loan  facility  with  up to  three
additional one-year  extensions subject to the lenders' approval.  The Revolving
Credit Facility will be the obligation of Acquisition Company and will rank pari
passu with the Notes.  The Term Loan Facility will be the obligation of American
Mobile Satellite Corporation and is secured by the stockholdings of the Company,
principally its stockholdings in AMRC and the Acquisition  Company,  and will be
effectively subordinated to the Revolving Credit Facility and the Notes. The New
Bank Financing is severally  guaranteed by Hughes,  Singapore  Telecom and Baron
Capital Partners,  L.P. (the "Bank Facility  Guarantors").  The Banks' placement
fee for the New Bank Financing is approximately $500,000.

The Revolving  Credit  Facility bears an interest rate,  generally,  of 50 basis
points above LIBOR and is unsecured, with a negative pledge on the assets of the
Acquisition Company and its subsidiaries  ranking pari passu with the Notes. The
Revolving  Credit  Facility will be reduced $10 million each quarter,  beginning
with the quarter ending June 30, 2002, with the balance due on maturity of March
31, 2003. Certain proceeds received by the Acquisition Company would be required
to repay and reduce the Revolving  Credit  Facility,  unless otherwise waived by
the  Banks  and the Bank  Facility  Guarantors:  (1) 100% of  excess  cash  flow
obtained by the Acquisition Company; (2) the first $25.0 million net proceeds of
the lease or sale of MSAT-2 received by the Acquisition  Company, and thereafter


                                      F-31

<PAGE>


75% of the remaining  proceeds  received from such lease or sale (the  remaining
25% may be retained by the  Acquisition  Company for business  operations);  (3)
100% of the proceeds of any other asset sales by the  Acquisition  Company;  (4)
50% of the net proceeds of any  offerings of the  Acquisition  Company's  equity
(the  remaining  50% to be retained  by the  Acquisition  Company  for  business
operations);  and (5) 100% of any major casualty  proceeds.  At such time as the
Revolving  Credit Facility is repaid in full, and subject to satisfaction of the
restrictive  payments provisions of the Notes, any prepayment amounts that would
otherwise  have  been used to  prepay  the  Revolving  Credit  Facility  will be
dividended to the Company.

The Term Loan Facility  bears an interest  rate,  generally,  of 50 basis points
above  LIBOR and is  secured  by the  assets  of the  Company,  principally  its
stockholdings in AMRC and the Acquisition  Company. The Term Loan Agreement does
not include any scheduled  amortization until maturity, but does contain certain
provisions for  prepayment  based on certain  proceeds  received by the Company,
unless otherwise waived by the Banks and the Bank Facility Guarantors:  (1) 100%
of excess cash flow  obtained by the  Company;  (2) the first $25.0  million net
proceeds of the lease or sale of MSAT-2 received by the Company,  and thereafter
75% of the remaining  proceeds  received from such lease or sale (the  remaining
25% to be retained by the Acquisition Company for business operations); (3) 100%
of the  proceeds  of any other asset  sales by the  Company;  (4) 50% of the net
proceeds  of any  equity  offerings  of the  Company  (the  remaining  50% to be
retained  by the  Company for  business  operations);  and (5) 100% of any major
casualty  proceeds of the Company.  To the extent that the Term Loan Facility is
repaid, the aforementioned proceeds that would otherwise have been used to repay
the Term Loan Facility will be used to repay and reduce the commitment under the
Revolving Credit Facility.


The Guarantees
- --------------

In connection  with the New Bank  Financing,  the Bank Facility  Guarantors have
agreed  to  extend  separate  guarantees  of  the  obligations  of  each  of the
Acquisition  Company  and the  Company  to the Banks,  which on a several  basis
aggregate  to $200  million.  In their  agreement  with each of the  Acquisition
Company and the Company (the "Guarantee Issuance Agreement"),  the Bank Facility
Guarantors  have  agreed to make  their  guarantees  available  for the New Bank
Financing.  The Guarantee  Issuance  Agreement will include  certain  additional
agreements of the Acquisition  Company and of the Company including with respect
to financial  performance of the  Acquisition  Company  relating to the ratio of
debt to EBITDA and service  revenue,  which,  if not met,  could, if not waived,
limit the Acquisition Company's ability to draw down on additional amounts under
the  Revolving  Credit  Facility  and  result  in a  default  under the New Bank
Financing  beginning in 1999. In exchange for the additional risks undertaken by
the Bank  Facility  Guarantors in connection  with the New Bank  Financing,  the
Company has agreed to compensate  the Bank Facility  Guarantors,  principally in
the form of 1 million  additional  warrants  and  repricing  and  extending  the
expiration date of 5.5 million warrants  previously issued  (together,  the "New
Guarantee Warrants").  The New Guarantee Warrants will be on terms substantially
similar, including with regard to pricing, as those issued as part of the Units.

Further,  in connection with the Guarantee Issuance  Agreement,  the Company has
agreed  to  reimburse  the  Bank  Facility  Guarantors  in the  event  that  the
Guarantors  are required to make payment  under the  Revolving  Credit  Facility
guarantees,  and, in connection with this Reimbursement  Commitment has provided
the Bank  Facility  Guarantors a junior  security  interest  with respect to the
assets of the Company, principally its stockholdings in AMRC and the Acquisition
Company.


Motorola Vendor Financing
- -------------------------

Motorola has agreed to provide the Acquisition  Company with up to $10.0 million
of vendor financing (the "Vendor Financing Commitment"), which will be available
to finance up to 75% of the purchase price of additional  network base stations.
Loans under this  facility will bear interest at a rate equal to LIBOR plus 7.0%
and will be  guaranteed by the Company and each  subsidiary  of the  Acquisition
Company.  The terms of such  facility  will  require  that  amounts  borrowed be
secured by the  equipment  purchased  therewith.  This  commitment is subject to
customary  conditions,  including due  diligence,  and there can be no assurance
that the facility will be obtained by the Acquisition  Company on these terms or
at all.

                          Independent Auditors' Report



To the Board of Directors and Stockholders
AMRC Holdings, Inc.:

We have audited the  accompanying  consolidated  balance sheet of AMRC Holdings,
Inc. and subsidiary (a  development  stage company) as of December 31, 1997, and
the related  consolidated  statements of operations,  stockholders'  equity, and
cash flows for the year ended December 31, 1997 and the period December 15, 1992
(date  of  inception)  to  December  31,  1997.  These  consolidated   financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is  to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects, the financial position of AMRC Holdings,  Inc.
and  subsidiary (a  development  stage company) as of December 31, 1997, and the
results of their operations and their cash flows for the year then ended and the
period  December 15, 1992 (date of inception) to December 31, 1997 in conformity
with generally accepted accounting principles.

The accompanying  consolidated  financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in note 5 to the
consolidated financial statements, the Company has not commenced operations, has
negative  working  capital of  $82,948,890,  and is  dependent  upon  additional
capital  contributions,  which  raises  substantial  doubt  about its ability to
continue as a going  concern.  Management's  plan in regard to these  matters is
also described in note 5. The consolidated  financial  statements do not include
any adjustments that might result from the outcome of this uncertainty.

                          (A Development Stage Company)

                   Notes to Consolidated Financial Statements
          for the period from December 15, 1992 (date of inception) to
                                December 31, 1997

(1) Summary of Significant Accounting Policies and Practices

         Nature of Business
         ------------------

         American Mobile Radio  Corporation  (AMRC) was incorporated on December
         15,  1992 in the State of  Delaware  as a wholly  owned  subsidiary  of
         American  Mobile  Satellite  Corporation  (AMSC)  for  the  purpose  of
         procuring  a digital  audio  radio  service  license  (DARS).  Business
         activity for the period December 15, 1992 through December 31, 1996 was
         insignificant.

         AMRC  Holdings,  Inc.  (the Company) was  incorporated  in the State of
         Delaware on May 16, 1997 for the purpose of constructing, launching and
         operating a domestic communications  satellite system for the provision
         of DARS. Pursuant to various financing  agreements entered into in 1997
         between  AMSC,  AMRC and  WorldSpace,  Inc.  (WSI),  WSI acquired a 20%
         interest in AMRC. In May 1997, AMSC and WSI exchanged their  respective
         interests in AMRC for all of the Company's common stock.

         Principles of Consolidation and Basis of Presentation
         -----------------------------------------------------

         The  consolidated  financial  statements  include the  accounts of AMRC
         Holdings, Inc. and its subsidiary,  AMRC. All significant  intercompany
         transactions and accounts have been eliminated.  The Company's board of
         directors have devoted  substantially all of their time to the planning
         and  organization  of the  Company  and to the  process  of  addressing
         regulatory  matters,  initiating  research  and  development  programs,
         conducting  market  research  and  securing  adequate  debt and  equity
         capital  for  anticipated  operations  and  growth.  Accordingly,   the
         Company's financial  statements are presented as those of a development
         stage  enterprise,  as prescribed by Statement of Financial  Accounting
         Standards  No.  7,  Accounting  and  Reporting  by  Development   Stage
         Enterprises.

         Cash and Cash Equivalents
         -------------------------

         The Company  considers  short-term,  highly liquid  investments with an
         original  maturity of three months or less to be cash  equivalents.  At
         December 31, 1997, the Company  maintained one bank account and held no
         short-term investments.

                   Notes to Consolidated Financial Statements
          for the period from December 15, 1992 (date of inception) to
                                December 31, 1997

         System Under Construction
         -------------------------

         The Company is currently developing its satellite system. Costs related
         to the  project  are being  capitalized  to the  extent  that they have
         future  benefits.  As of December  31,  1997,  all amounts  recorded as
         system under  construction  relate to costs  incurred in obtaining  FCC
         licenses and approvals.

         On October 16,  1997,  the Federal  Communications  Commission  ("FCC")
         granted  AMRC  a  license  to  launch  and  operate  two  geostationary
         satellites  for the  purpose of  providing  digital  audio radio in the
         United States in the 2332.5 - 2345 MHz (space-to-earth) frequency band,
         subject to achieving  certain  technical  milestones and  international
         regulatory  requirements.  The  license  is valid for eight  years upon
         successful  launch  and  orbital  insertion  of  the  satellites.   The
         Company's  license  requires  that it comply  with a  construction  and
         launch  schedule  specified  by the FCC for each of the two  authorized
         satellites.  The FCC has the authority to revoke the authorizations and
         in  connection  with 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.

         The license asset value  consists of the total payments made to the FCC
         for the  license  of  $90,030,889.  Associated  with  this  license  is
         capitalized interest of $1,901,473.

         During  1996,  the Company  adopted  Statement of Financial  Accounting
         Standards  (SFAS) No. 121,  Accounting for the Impairment of Long-lived
         Assets  and for  Long-lived  Assets to be Disposed  of (SFAS No.  121).
         SFAS No. 121  requires  that  long-lived  assets to be held and used be
         reviewed  by the Company for impairment  whenever  events or changes in
         circumstances  indicate that the carrying amount of an asset may not be
         recoverable.  An  impairment loss is recognized  when the  undiscounted
         net  cash  flows  associated  with the asset are less than the  asset's
         carrying  amount. Impairment losses, if any, are measured as the excess
         of  the  carrying  amount of the asset over its  estimated  fair market
         value.  The  adoption of SFAS No. 121 did not have a material impact on
         the  Company's financial position or results of operations.

                   Notes to Consolidated Financial Statements
          for the period from December 15, 1992 (date of inception) to
                                December 31, 1997


(1)      Continued

         Income Taxes
         ------------

         The Company  accounts for income taxes in accordance  with Statement of
         Financial  Accounting  Standards No. 109,  Accounting for Income Taxes.
         Deferred income taxes are recognized for the tax consequences in future
         years of  differences  between the tax bases of assets and  liabilities
         and the financial reporting amounts at each year-end,  based on enacted
         tax laws and statutory tax rates applicable to the periods in which the
         differences are expected to affect taxable income. Valuation allowances
         are  established  when  necessary to reduce  deferred tax assets to the
         amount  expected to be  realized.  Income tax expense is the sum of tax
         payable for the period and the change during the period in deferred tax
         assets and liabilities.

         Use of Estimates
         ----------------

         The  preparation  of the Company's  financial  statements in conformity
         with generally accepted  accounting  principles  requires management to
         make  estimates  and  assumptions  that affect the reported  amounts of
         assets and liabilities at the date of the financial  statements and the
         reported amounts of expenses during the reported period.  The estimates
         involve  judgments with respect to, among other things,  various future
         factors  which are  difficult  to predict and are beyond the control of
         the Company.  Significant  estimates include valuation of the Company's
         investment in the DARS license and benefit for income taxes and related
         valuation allowances.  Accordingly,  actual  amounts  could differ from
         these estimates.

(2)      Related Party Transactions
         --------------------------

         The  Company  had  related  party   transactions   with  the  following
         shareholders:

         AMSC
         ----

         In 1997,  AMSC  contributed  $142,534  for the Company to establish the
         original  application  for  the FCC  license.  On March 28,  1997,  the
         Company  received  $1,500,000  as  a capital  contribution  from  AMSC.
         During  the fiscal year, AMSC incurred costs for operating  expenses of
         the  Company and established an intercompany balance of $55,435.

         WSI
         ---

         On March  28,  1997,  the  Company  received  $1,500,000  as a  capital
         contribution from WSI. The Company issued WSI 25 shares of common stock
         for this consideration.

         On April 16, 1997,  the Company  received  $14,977,777  from WSI, which
         represented  $6,000,000  as  an  additional  capital  contribution  and
         $8,977,777 as a six-month bridge loan (see note 3).

         On May 16, 1997, the Company obtained a $1,000,000 working capital loan
         facility  from WSI.  During  fiscal year 1997,  the  Company  drew down
         $663,531 against the facility (see note 3).

         On October 16, 1997, the Company  received  $71,911,111 from WSI, which
         represented  an  additional  $13,522,223  under  the  bridge  loan  and
         $58,388,889 under the additional amounts loan (see note 3).

         In addition to financing,  the Company has relied upon certain  related

(3)      Loans Payable

         In March 1997, AMRC entered into a series of agreements  (Participation
         Agreement)  with AMSC and WSI in which both companies  provide  various
         equity  and  debt  funding  commitments  to  AMRC  for the  purpose  of
         financing the activities of AMRC in connection  with the  establishment
         of a DARS  satellite  system in the  United  States.  On May 16,  1997,
         certain  portions  of the  Participation  Agreement  were  subsequently
         ratified with  substantially  the same terms and  conditions  under the
         Bridge  Loan,  Additional  Amounts  Loan  and  Working  Capital  Credit
         Facility (Loan Agreement).

         Additional Amounts Loan
         -----------------------

         On October 16, 1997, the Company  executed the additional  amounts loan
         with WSI and received  proceeds of  $58,218,889  for a loan with a face
         amount of $58,388,889. This loan is a six-month loan at LIBOR plus five

         Working Capital Loan
         --------------------

         On May 16, 1997, the Company executed the working capital loan with WSI
         whereby the company would receive  proceeds of $920,000 for a loan with
         a face amount of $1,000,000. The Company drew down $663,531 against the
         line of credit through December 31, 1997. This loan is a six-month loan
         at LIBOR plus five percent per annum,  with interest rates ranging from
         10.91  percent to 11 percent as the  components of the loan were rolled
         over in November 1997.


(4)      Options

         The Company issued WSI three options.  Under the first option,  WSI may
         purchase  97.2222  shares of common  stock at $241,714  per share.  The
         option may be  exercised  in whole or in  incremental  amounts  between
         April 16, 1998 and October 16, 2002,  subject to prior  approval of the
         FCC to the extent  that such  exercise  would  constitute  transfer  of
         control. Under certain circumstances,  AMSC may require WSI to exercise
         the option in whole.  The Company  allocated $ 1,250,000 to the option,
         based upon an independent  valuation.  Under the second option, WSI may
         purchase  128.8876  shares at  $477,005  per  share.  The option may be
         exercised  between  October 16, 1997 and October 16,  2003,  subject to
         prior  approval  of the FCC to the  extent  that  such  exercise  would
         constitute transfer of control.  The Company allocated $ 170,000 to the
         option,  based upon an independent  valuation.  Under the third option,

                          (A Development Stage Company)

                   Notes to Consolidated Financial Statements
          for the period from December 15, 1992 (date of inception) to
                                December 31, 1997


(5)      Accumulated Deficit
         -------------------

         The Company is devoting its efforts to develop,  construct and expand a
         digital audio radio network.  This effort involves substantial risk and
         future  operating  results  will be  subject to  significant  business,
         economic,  regulatory,  technical,  and competitive  uncertainties  and
         contingencies.  These factors  individually  or in the aggregate  could
         have an adverse effect on the Company's  financial condition and future
         operating results and create an uncertainty as to the Company's ability
         to continue as a going concern. The financial statements do not include
         any adjustments that might be necessary should the Company be unable to
         continue as a going concern.

         In order to commence  satellite-based radio broadcasting  services, the
         Company will require  substantial  funds to develop and  construct  the
         DARS system, develop and launch radio communications satellites, retire
         debt incurred in connection  with the  acquisition  of the DARS license
         and to sustain operations until it generates positive cash flow. At the
         Company's current stage of development,  economic  uncertainties  exist
         regarding   successful   acquisition  of  additional  debt  and  equity
         financing and ultimate profitability of the Company's proposed service.
         The Company has not commenced  construction  of its satellites and will
         require  substantial  additional  financing before it is able to do so.
         Failure to obtain the  required  long-term  financing  will prevent the
         Company from  realizing its objective of providing  satellite-delivered
         radio  programming.  Management's  plan to fund  operations and capital
         expansion  includes the additional  sale of debt and equity  securities
         through public and private sources.  There are no assurances,  however,
         that such financing will be obtained.


   (6)   Interest Cost
         -------------

         The Company  capitalizes  a portion of its interest cost as a component
         of the  system  under  construction.  The  following  is a  summary  of
         interest cost incurred during 1997:


Interest cost capitalized                                             $1,901,473
Interest cost charged to expense                                         549,447
- --------------------------------------------------------------------------------

Total interest cost incurred                                          $2,450,920
- --------------------------------------------------------------------------------

Interest costs incurred prior to the award of the license were expenses.

                          (A Development Stage Company)

                   Notes to Consolidated Financial Statements
          for the period from December 15, 1992 (date of inception) to
                                December 31, 1997


(7)      Income Taxes
         ------------

         For the period from  December 15, 1992 (date of  inception) to December
         31, 1997,  the Company  filed a  consolidated  return with its majority
         stockholder, AMSC. The Company generated net operating losses and other
         tax benefits  which were not utilized by AMSC. As no formal tax sharing
         agreement has been  finalized,  the Company was not compensated for the
         net operating losses.  Had the Company filed on a stand alone basis, it
         would  have  had no  tax  provision  as the  deferred  tax  benefit  of
         approximately  $650,000  would  have been fully  offset by a  valuation
         allowance.


(8)      Commitments and Contingencies
         -----------------------------

         The FCC has established certain system development milestones that must
         be met for the company to maintain  its license to operate the systems.
         The Company believes that it is proceeding into the system  development
         as planned and in accordance with the FCC milestones.


(9)      Subsequent Events
         -----------------

         On March 20,  1998,  the  Company  entered  into an  agreement  for the
         construction  of two  satellites,  two  launch  vehicles,  and  related
         equipment,  services and spare parts,  including launch  services.  The
         total  commitment,  excluding  financing  fees, is $376 million.  These
         amounts are due upon completion of certain  milestones.  In March 1998,
         the  Company  made  the first milestone payment of $5 million which was
         funded through additional borrowings from WSI.

                          INDEPENDENT AUDITORS' CONSENT


The Board of Directors
AMRC Holdings, Inc.:


We consent to the  incorporation  by  reference in the  registration  statements
(Nos.  33-72852,  33-34250,  33-91714  and   333-30099) on Forms S-8 of American
Mobile Satellite Corporation of our report dated April 10, 1998, with respect to
the  consolidated  balance  sheet  of AMRC  Holdings,  Inc.  and  Subsidiary  (a
development stage company) as of December 31, 1997 and the related  consolidated
statements of operations, stockholders' equity and cash flows for the year ended
December 31, 1997 and for the period from  December 15, 1992 (date of inception)
to December 31, 1997,  which report appears in the December 31, 1997 Form 10-K/A
of American Mobile Satellite Corporation dated April 15, 1998.

Our report, dated April 10, 1998, contains an explanatory  paragraph that states
that the Company has not commenced operations, has a working capital deficit and
is dependent upon additional capital contributions which raise substantial doubt
about its ability to continue as a going  concern.  The  consolidated  financial
statements do not include any adjustments  that might result from the outcome of
that uncertainty.
