ITEM 1.  BUSINESS

                            GENERAL INFORMATION

BUSINESS SEGMENTS

     COMSAT  Corporation  (COMSAT,  the corporation or Registrant)  reports
operating  results and financial data in two business  segments:  Satellite
Services and Network Services.

     The Satellite  Services segment consists of the  corporation's  COMSAT
World Systems (CWS) and COMSAT Mobile Communications (CMC) businesses.  CWS
provides voice, data, video and audio  communications  services between the
U.S. and other  countries using the satellite  system of the  International
Telecommunications  Satellite Organization (INTELSAT).  CMC provides voice,
data,  fax,  telex and  information  services for ships,  aircraft and land
mobile  applications  throughout  the world  primarily  using the satellite
system of the International Mobile Satellite Organization (Inmarsat).

     The Network  Services  segment  consists of the  corporation's  COMSAT
International  (CI),  COMSAT  Laboratories  (Labs) and Government  Programs
businesses. CI operates an integrated group of telecommunications companies
that  are  engaged   principally   in  providing   individualized   digital
communications  network  solutions  to  business  clients  and  carriers in
high-growth  emerging markets overseas.  Labs provides technical consulting
in  the  design  and   development  of  advanced   digital   communications
technologies  and  also  designs,   develops  and  licenses  communications
products for satellite  access,  compression  and networking  applications.
Government  Programs includes the operations of COMSAT General  Corporation
(COMSAT General) and COMSAT Government Services, Inc. (CGSI), both of which
are wholly-owned  subsidiaries of the corporation.  The Labs and Government
Programs sectors of Network Services now include certain non-manufacturing,
telecommunications  contracts and businesses that were previously  reported
as part of COMSAT RSI, Inc. (CRSI) in the Technology Services segment.

     The  revenues,  operating  income  (loss) and  identifiable  assets by
business segment,  for each of the last three years are shown in Note 15 to
the financial statements.

      During the second quarter of 1997, the  corporation  began  accounting
for the operations of both Ascent  Entertainment  Group,  Inc. (Ascent) and
substantially  all of the  manufacturing  assets  of CRSI  as  discontinued
operations.  See Note 2 to the financial  statements.  Ascent,  through its
subsidiaries,  provides  on-demand  in-room  entertainment  programming and
information  services  primarily to the domestic lodging  industry,  owns a
professional  basketball  team and a professional  hockey team, owns a film
and television  production  company,  and provides  satellite  distribution
support   services  to  the  National   Broadcasting   Company  (NBC).  The
corporation   distributed  its  80.67%  ownership  interest  in  Ascent  to
shareholders on June 27, 1997.

                                    2

<PAGE>


     CRSI designs,  manufactures and integrates earth stations,  as well as
wireless and  advanced  antenna  systems.  In March 1998,  the  corporation
entered into a stock purchase  agreement to sell substantially all of CRSI.
See  "Management's  Discussion  and  Analysis of  Financial  Condition  and
Results of Operations-Outlook." The sale of substantially all of the assets
and  liabilities  of JEFA  Wireless  Systems,  a  subsidiary  of CRSI,  was
completed in a separate transaction in February 1998. Also included as part
of  discontinued  operations is  Electromechanical  System,  Inc.  (EMS), a
wholly-owned  subsidiary  of CRSI,  and an  equity  ownership  interest  in
Plexsys International  Corporation  (Plexsys),  which are being retained by
COMSAT per the terms of the stock purchase agreement, pending evaluation of
available alternatives.  The long-term contract for construction of a radio
telescope in Greenbank,  West Virginia also is to be retained and completed
by the corporation in connection with the stock purchase agreement

     Prior  to  the  second  quarter  of  1997,  the  corporation  reported
operating   results  and  financial  data  in  three   business   segments:
International  Communications  (consisting of CWS, CMC and CI),  Technology
Services (consisting of CRSI and the Labs) and Entertainment (consisting of
Ascent).

     The corporation had  approximately  2,732 employees as of December 31,
1997,  approximately  1,367  of whom  were  employed  in the  corporation's
continuing  operations.  None of the  employees is  represented  by a labor
union,  except  for  approximately  68  employees  working  for CRSI on the
construction  of the Greenbank  radio  telescope.  The union  employees are
expected  to become  employees  of COMSAT  or a  subsidiary  on or prior to
consummation of the CRSI sale.

COMMUNICATIONS SATELLITE ACT OF 1962

     COMSAT was  incorporated  in 1963 under  District of Columbia  law, as
authorized by the Communications Satellite Act of 1962 (the Satellite Act).
In 1993, COMSAT changed its corporate name from  "Communications  Satellite
Corporation"  to  "COMSAT   Corporation."   COMSAT  is  not  an  agency  or
establishment of the U.S. Government.  The U.S. Government has not invested
funds in COMSAT,  guaranteed  funds  invested in COMSAT or  guaranteed  the
payment of dividends by COMSAT.

     Although  COMSAT is a private  corporation,  the Satellite Act governs
certain aspects of COMSAT's structure, ownership and operations,  including
the  following:  three  of  COMSAT's  15  directors  are  appointed  by the
President  of the United  States  with the advice and consent of the United
States  Senate;  COMSAT's  issuance of capital stock and borrowing of money
must be authorized by the Federal  Communications  Commission (FCC);  there
are  limitations on the classes of persons that may hold shares of COMSAT's
common  stock and on the number of shares a person or class of persons  may
hold;  and, on matters  that may affect the  national  interest and foreign
policy of the United  States,  COMSAT's  representatives  to  INTELSAT  and
Inmarsat  receive  instructions  from the  U.S.  Government.  Congress  has
reserved  the right to amend the  Satellite  Act, and  amendments,  if any,
could materially affect the corporation.

                                     3

<PAGE>

     In  June  1997,  a bill  captioned  as the  "Communications  Satellite
Competition and  Privatization  Act of 1997" (H.R.  1872) was introduced in
the U.S. House of  Representatives  by Congressmen Thomas Bliley and Edward
Markey.  If enacted as proposed,  H.R.  1872 would have a material  adverse
effect on  COMSAT's  financial  condition  and  results  of  operations  by
restricting or prohibiting COMSAT from offering certain existing and future
services via the INTELSAT and Inmarsat  satellite  systems,  would  relieve
major  customers  from existing  contracts with the  corporation  and would
damage or impair  COMSAT's  investment  in INTELSAT  and Inmarsat by, among
other  actions,  requiring  the return or orbital  positions  and  spectrum
currently needed in INTELSAT and Inmarsat  operations.  Moreover,  the bill
would direct the FCC to require  direct  access to INTELSAT and Inmarsat in
the U.S.  market and  discontinue  COMSAT's  exclusive  provider  role. The
corporation  is, and plans to continue,  opposing  H.R. 1872 in its present
form.  For a discussion of H.R.  1872,  see  "Management's  Discussion  and
Analysis of Financial Condition and Results of Operations-Outlook."

GOVERNMENT REGULATION

     Under  the  Satellite  Act,  the  International   Maritime   Satellite
Telecommunications  Act of 1978 (the Inmarsat  Act) and the  Communications
Act of 1934,  as amended  (the  Communications  Act),  COMSAT is subject to
regulation  by the FCC  with  respect  to its  capital  and  organizational
structure,  as well as CWS's  and CMC's  plant,  operations,  services  and
rates.  FCC  decisions  and policies  have had and will  continue to have a
significant impact on the corporation. For a discussion of certain of these
matters see Note 9 to the financial statements.

     In April 1997, the corporation  petitioned the FCC for  classification
as a non-dominant carrier and for regulatory forbearance. Because COMSAT is
currently classified by the FCC as a dominant carrier, COMSAT is subject to
rate  base/rate-of-return  regulation  for the services it provides via the
INTELSAT  system,  is  required to file  tariffs for voice,  data and video
service  on 14  days'  notice,  and is  subject  to  structural  separation
requirements.  In  contrast,  COMSAT's  competitors  are  entirely  free of
rate-of return  regulation,  tariff  regulation  and structural  separation
requirements.

     The petition requests that limits on the corporation's  rate of return
and structural  separation  requirements be removed and that CWS be allowed
to change its tariff rates and  introduce  new services on one-day  notice.
The  corporation  believes  that  the  relief  requested  will  enable  the
corporation to compete more effectively under current market conditions. In
particular,  lifting rate-of-return  regulation and more flexible tariffing
requirements,  are expected to permit the  corporation to offer customers a
wider  range of  services  at lower  prices by  eliminating  inefficiencies
associated with structural separation and cost-of-services rules.

     The petition  would not eliminate all FCC  regulatory  oversight  over
COMSAT or all existing regulatory constraints. If COMSAT is classified as a
non-dominant carrier or the FCC exercises its forbearance authority, COMSAT
would continue to be governed by the reasonableness  and  nondiscrimination
requirements of the Communications Act, would still file tariffs, and would
remain subject to the FCC's  complaint  procedures.  In addition,  COMSAT's
capital  structure  and  debt-financing  activities  would  continue  to be
regulated by the FCC under the Satellite Act. See "Management's  Discussion
and Analysis of Financial  Condition and Results of  Operations-  Liquidity
and Capital  Resources."  The Satellite  Act provides  that no  shareholder


                                     4

<PAGE>

(other than communications common carriers authorized to hold shares by the
FCC) may own more than 10% of the corporation's  common stock.  COMSAT also
is barred from providing  domestic  service in the U.S., which precludes it
from providing "one-stop" shopping for international and domestic services.
In addition,  unlike its  competitors,  COMSAT is only permitted to provide
earth station services  through a separate  subsidiary.  See  "Management's
Discussion and Analysis of Financial  Condition and Results of Operations -
Outlook"  for a  discussion  of proposed  legislation  which  could  affect
certain of those requirements.

     CI's companies operate in various developing countries and are subject
to  regulation  by the local  regulatory  authorities  in those  countries.
Because the regulatory  environment in those countries is rapidly  evolving
as the local  economies are  developing,  CI's  companies  face  increasing
business  uncertainties  which  could  have  an  adverse  effect  on  their
operations in those  countries.  For a discussion  of a pending  regulatory
proceeding  in Argentina  affecting  COMSAT  Argentina,  see  "Management's
Discussion   and   Analysis   of   Financial   Condition   and  Results  of
Operations-Outlook-Network Services."

                            SATELLITE SERVICES


COMSAT WORLD SYSTEMS

     SERVICES.  COMSAT World Systems (CWS) provides  satellite capacity for
telephone, data, video and audio communications services between the United
States  and the rest of the world  using the  global  network  of  INTELSAT
satellites.  CWS's  customers  include  U.S.  international  communications
common  carriers,  teleports,  private  network  providers,   multinational
corporations,   U.S.   and   international   broadcasters,   news-gathering
organizations, digital audio companies and the U.S. government.

     The largest  portion of CWS's  revenues  comes from leasing  full-time
voice grade half-circuits  (two-way  communications  links between an earth
station and an INTELSAT  satellite)  to U.S.  international  communications
common carriers. The three largest carrier customers are AT&T Corp. (AT&T),
MCI International  Inc. (MCI) and Sprint  Communications  Company (Sprint).
CWS offers  significant  discounts to  customers  entering  into  long-term
commitments for full-time voice-grade  half-circuits.  Approximately 93% of
all eligible voice-grade half-circuits are now under such commitments.

     CWS's voice and data services are primarily  digital,  which  provides
higher quality  transmissions  than analog  services.  CWS's  International
Digital  Route  (IDR)   service,   for  example,   makes  it  possible  for
communications  carriers  to  provide  digital  public-switched   telephone
network  circuits.  The carriers  apply  techniques  to such  circuits that
permit  a  single  digital  circuit  to  handle  multiple  telephone  calls
simultaneously.

     For private-line  customers,  CWS offers an all-digital  International
Business  Service  (IBS),  as well as an  international  VSAT  (Very  Small
Aperture  Terminal)  service.  IBS  offers  customers  high-speed,  digital
communications  for voice,  data,  facsimile and video  conferencing  using
on-premise  earth  stations that  eliminate  the need for costly  land-line
connections.  At year-end 1997,  approximately 95% of CWS's IBS traffic was
covered  by  long-term   commitments.   CWS's  customers  have  established

                                     5

<PAGE>


international  VSAT  networks  in both  Latin  America  and  Europe.  Using
on-premise  antennas  as  small  as 1.8  meters  in  combination  with  the
high-power satellites in the INTELSAT network,  corporations doing business
internationally   can  deliver   communications  to  multiple  sites.  Used
primarily  for data  transmissions,  VSATs can also  accommodate  voice and
video communications.

     To the growing international broadcasting community, CWS provides both
digital and analog  transmission  services on a  long-term,  short-term  or
occasional as-needed basis. With the introduction of the INTELSAT VII, VIIA
and VIII satellites (see "Item 2. Properties -- INTELSAT Satellites"),  CWS
has  expanded  the  availability  of  high-power,   flexible  capacity  for
broadcasters and satellite news gatherers.

     To  maintain  the  quality  of  the  INTELSAT  network,  CWS  provides
tracking,  telemetry,  control and  monitoring  services  to  INTELSAT  and
engages  in a program  of  research  and  development  to  ensure  that the
satellite  system  accommodates  the  latest  communications  technologies,
including  broadband,  integrated  services digital  networks  (ISDN),  and
asynchronous transfer mode (ATM).

     INTELSAT.  INTELSAT  is a  142-nation  organization  headquartered  in
Washington,   D.C.   It   operates   under   three   agreements:   (1)   an
intergovernmental  agreement;  (2) a  headquarters  agreement with the U.S.
Government;  and  (3)  an  operating  agreement  signed  by  each  nation's
government or designated telecommunications entity (a signatory). COMSAT is
the U.S. signatory. It represents the United States in INTELSAT, subject to
instructions  from the  Department of State (in concert with the Department
of Commerce and the FCC) on matters  that may affect the national  interest
and foreign policy of the United States.

     Each  signatory has rights and  obligations  in INTELSAT  analogous to
those of a partner.  Each owns an  investment  share,  makes  proportionate
contributions  to  INTELSAT's  capital  costs,  and receives  proportionate
distributions  of INTELSAT's  net revenues  after  deductions for operating
expenses.  The investment  shares are readjusted as of March 1 of each year
to approximate the Signatories' respective portions of the total use of the
INTELSAT  space  segment for the previous six months.  COMSAT's  investment
share, the largest in INTELSAT, was 18.0% as of December 31, 1997 and 19.1%
as of December 31, 1996.

     Signatories  also pay INTELSAT for their use of the satellite  system.
In 1997, INTELSAT  established a range of 17-21% for the pretax target rate
of return on signatory capital used by another signatory or from non-owners
who use the  satellite  system.  The actual  rate of return on  signatory's
capital was 18.3% in 1997. In 1998, COMSAT expects to receive a pretax rate
of return of between 15% to 19% on its capital investment after appropriate
accounting  adjustments.  CWS realized revenue from its INTELSAT ownership,
net of use charges paid, of $35.4 million in 1997.

     At December 31, 1997, total INTELSAT Owners' Equity was  approximately
$2.04 billion.

                                     6

<PAGE>

     At year end 1997,  approximately  78% of CWS's IDR, IBS and FM traffic
was  under  long  term  commitments  with  INTELSAT.   CWS  has  short-term
commitments with INTELSAT for the remaining  portion of its FM, IDR and IBS
traffic.  CWS also enters into commitments with INTELSAT for video traffic,
which  vary in length  depending  on the length of  commitments  from CWS's
customers.

     Under the  INTELSAT  agreements,  the member  nations  that  authorize
international  satellite  systems  separate  from  INTELSAT are required to
ensure  that such  systems are  technically  compatible  with the  INTELSAT
system and will not cause significant economic harm to the INTELSAT system.
Beginning in 1990,  INTELSAT  initiated  certain reforms to its process for
coordinating  with  these  separate   satellite   systems.   These  reforms
culminated in 1997,  when  INTELSAT  decided to  effectively  eliminate the
economic harm test.  As a result,  there is no longer a limit on the number
of circuits  that a separate  system can provide  beyond  which it would be
deemed  to cause  significant  economic  harm to the  INTELSAT  system.  In
addition, the submission of non-technical information is no longer required
in connection with INTELSAT  coordination  procedures.  For a discussion of
separate satellite systems competition to CWS, see "Management's Discussion
and Analysis of Financial Condition and Results of Operations-Outlook"  and
Note 9 to the financial statements.

     The  corporation  continues  to  promote  efforts to  restructure  the
INTELSAT  satellite  system.  For a  discussion  of the  current  status of
INTELSAT  restructuring,  see  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations-Outlook."

     INTELSAT  generally  procures  spacecraft  and launch  services  under
long-term, multi-satellite contracts which provide for payments by INTELSAT
over the contract  periods.  Under the  satellite  construction  contracts,
approximately  60% of spacecraft cost is typically paid to the manufacturer
during  construction prior to spacecraft  delivery and satellite launch. In
addition,  approximately 20% typically is paid after the satellite has been
placed in orbit and has  satisfactorily  completed  in-orbit  testing.  The
remaining  portion  of the  spacecraft  cost  is  payable  periodically  as
performance  incentives  over the  designated  design life of the satellite
contingent upon continued  successful operation of the satellite during the
respective periods.

     Under  the  launch  service  contracts,   launch  services  costs  are
typically paid in quarterly  installments with the final payment due at the
end of the  planned  launch  period.  Launch  payments  are payable in full
whether or not the launch has resulted in launch success.

     INTELSAT has purchased launch and  post-separation  insurance coverage
for  possible  losses that may occur during the launch and  subsequent  one
year periods for satellites  scheduled for launch during 1998. The coverage
includes the cost of the satellite and launch services, as well as the cost
of  the  insurance  itself.  The  corporation   typically  buys  additional
insurance to cover its capitalized interest associated with the satellites.
Neither the  corporation  nor  INTELSAT  has  procured  insurance  to cover
in-orbit  failures beyond one year after launch.  While the corporation and
INTELSAT typically procure insurance coverage of the type described,  there
can  be  no  assurance  that  insurance   coverage  will  be  available  on
commercially  reasonable  terms or purchased by INTELSAT or the corporation
for future launches.

                                     7

<PAGE>


     Effective  January 1, 1998,  the  corporation  changed its  accounting
policy with respect to the cost of series  satellites  lost at launch or in
orbit and its  accounting  policy  with  respect to  satellite  performance
incentives  paid  to  manufacturers.   See  ""Management's  Discussion  and
Analysis of Financial Condition and Results of Operations-Outlook."

     INTELSAT  generally offers its customers  (including COMSAT) long-term
commitments for transponder capacity of one, five, ten or fifteen years for
a range of services at tariff rates which are  progressively  lower for the
longer term commitment  periods. As of December 31, 1997, certain customers
of  INTELSAT,  including  COMSAT,  had  long-term  commitments  in  effect,
representing  approximately  70% and 74% of the total  analog  and  digital
services  traffic,  respectively.  Over  75%  of the  commitments  are fo a
fifteen year term.

     COMPETITION.  CWS competes with operators of high capacity fiber-optic
and other submarine cables in service along major traffic routes worldwide.
CWS's major carrier customers (including its three largest customers, AT&T,
MCI and Sprint) are co-owners of submarine cables.

     COMSAT  is   currently   the  only  U.S.   entity   that  may  provide
international  space segment to customers  using  INTELSAT  satellites.  In
connection with CWS's petition for non-dominant  status (discussed  below),
several of CWS's  customers have asked the FCC to allow some form of direct
access to the INTELSAT  system.  The corporation has opposed these requests
and believes that the Satellite Act requires U.S.  access to INTELSAT to be
obtained through COMSAT.

     In November 1997, the FCC issued an order in its "DISCO-II" rulemaking
proceeding addressing,  among other matters, COMSAT's provision of INTELSAT
services  within the United States.  The FCC ruled that,  before COMSAT may
provide such  service,  it must first waive the limited  immunity from suit
which it has with  respect to its actions as U.S.  Signatory  to  INTELSAT.
COMSAT has  appealed  that ruling on the ground  that its limited  immunity
arises from international agreements entered into by the U.S. which may not
be abrogated by the FCC.

     TARIFFS AND REVENUES.  Under the Satellite Act and the  Communications
Act,  COMSAT is  subject  to  regulation  by the FCC with  respect to CWS's
communications  services  and the rates  charged  for those  services.  CWS
provides  its  services  on a  non-discriminatory  basis to all  customers,
either under  tariffs  filed with the FCC or on the basis of  inter-carrier
contracts.

     CWS  filed  a   petition   for   rulemaking   with  the  FCC   seeking
incentive-based  regulation of its multi-year,  switched-voice services for
carriers in January 1992. In the absence of FCC action on the petition, CWS
filed a petition for partial relief in July 1994.  This petition  requested
expedited FCC action to approve  streamlined  tariff  procedures for all of
CWS's INTELSAT satellite services.  The petition was also accompanied by an
extensive  economic  study  which  concluded  that  CWS  faces  substantial
effective  competition in all  geographic and service market  segments from
existing and planned fiber optic cables, separate satellite facilities, and
regional and foreign satellite systems, and that its access to the INTELSAT
system  does not  confer  upon CWS any  market  power in the  provision  of
transoceanic  telecommunications facilities. The FCC has not acted on CWS's
1992  petition,  but in August 1996 the FCC issued an order  granting CWS's
1994 request for streamlined  tariffing for its  switched-voice and private
line  services.  The  FCC did  not  grant  CWS's  request  for  streamlined
tariffing  of its video  services,  but invited CWS to file a new  petition

                                     8

with updated data seeking such relief,  which CWS did in October 1996. That
petition  was  granted  by the FCC in  August  1997 with  respect  to CWS's
full-time video and audio services. Petitions for reconsideration or review
of the FCC's  August 1996 and August 1997 orders were filed by one of CWS's
separate system competitors and are now pending before the FCC.

     In  April  1997,  the  corporation  formally  petitioned  the  FCC  to
re-classify it as a  non-dominant  carrier or,  alternatively,  forbearance
from dominant carrier  regulation  pursuant to Section 10(c) of the Telecom
Act of 1996. The corporation  expects that the FCC will act on the petition
in 1998. See "Government Regulation," "Management's Discussion and Analysis
of Financial Condition and Results of Operations-Outlook" and Note 9 to the
financial statements.

     CWS has entered into  inter-carrier  contracts  with each of its three
largest customers,  AT&T, MCI and Sprint. Pursuant to those contracts,  CWS
reduced its rates for 10- and 15-year IDR and TDMA digital "base"  circuits
activated prior to January 1, 1992, and also reduced its rates beginning in
1996 for 7-year and longer IDR and TDMA circuits activated after January 1,
1992. Additional rate reductions occurred on January 1, 1997.

     In 1997, COMSAT filed tariff rate reductions of between 8% and 10% for
IBS and VSAT  services.  In addition,  higher  speeds and larger  bandwidth
sizes were made  available to  accommodate  the growing  demand of Internet
services.

     Approximately 47% of the corporation's  consolidated  revenues in 1997
were  derived  from  CWS's  services  (compared  to 50% in 1996 and  1995).
Approximately 9% of the  corporation's  consolidated  revenues in 1997 were
derived  from CWS's  services to AT&T.  Also in 1997,  CWS's three  largest
customers,  AT&T, MCI and Sprint, were the source of approximately 20%, 19%
and 8%, respectively, of CWS's revenues.

COMSAT MOBILE COMMUNICATIONS

     COMSAT    Mobile     Communications     (CMC)    provides    satellite
telecommunications  services  for  maritime,  aeronautical  and land mobile
applications,  primarily using Inmarsat  satellites and COMSAT's land earth
stations  in  Connecticut  and  California,  which serve the  Atlantic  and
Pacific  Ocean  Regions,  respectively,  and in Malaysia and Turkey,  which
serve the Indian Ocean Region.  These  stations  enable CMC to offer global
coverage for its  services.  There are currently  more than 104,000  mobile
terminals  operating  in the  Inmarsat  system.  As  described  below,  CMC
provides a full range of voice, facsimile, data and telex services, as well
as certain value-added services.

     MARITIME SERVICES.  CMC provides satellite services for communications
to and from ships and other vessels.  Customers for these services  include
transport ship operators, cruise ships and their passengers, fishing vessel
operators,  oil and mining  interests,  pleasure boat operators,  U.S. Navy
ships and foreign telecommunications administrations.

                                     9

<PAGE>


     In addition to standard  telephony  services,  CMC's services  include
group call  messaging  to a fleet of ships,  electronic  mail  services,  a
direct-dial  telephone  service for  passengers  and crew on board ships, a
news summary  distribution  service,  access to data bases through personal
computers,   and  other  office   communications   services  for  facsimile
transmissions,   worldwide  teleconferencing  and  current  financial  news
reports.

     In 1997,  COMSAT entered into a memorandum of  understanding  with the
U.S.  Coast  Guard  (USCG)  and  the  National   Oceanic  and   Atmospheric
Administration (NOAA) to provide Inmarsat standard-C services in support of
USCG position reporting and NOAA survey programs.

     CMC offers two digital  services,  Inmarsat-B and  Inmarsat-M,  in the
Atlantic,  Pacific and Indian Ocean Regions.  These  services  provide more
efficient use of the Inmarsat  satellite  capacity,  help to  significantly
lower the cost of using satellite communications,  and expand the potential
customer  base for  maritime  and land mobile  services.  CMC also offers a
multi-channel  version of  Inmarsat-M  service that allows cruise ships and
other  high-volume users to increase their channel capacity and offer lower
rates to their customers.

     In 1997,  CMC  entered  into a five year  marketing  and  distribution
agreement with  Morsviazsputnik  to expand  distribution of CMC services to
Russian-flagged  vessels. In addition, CMC has entered into agreements with
Telecom Italia, Videsh Sanchar Nigam Limited (VSNL), OTE and other Inmarsat
signatories  to permit  those  entities  to  resell  CMC  services  through
"hosting"   arrangements,   pursuant   to   which   the   unique   Inmarsat
identification  code of  each  entity  is  "hosted"  at  CMC's  land  earth
stations,  allowing their customers to use CMC services in other regions in
which such  entities  do no have  their own  facilities.  CMC is  currently
examining similar arrangements with resellers in other markets.

     In 1997, CMC entered into a teaming  arrangement  with AT&T to provide
satellite communications for "Afloat Personnel Telecommunications Services"
on board U.S. Navy  vessels.  CMC has provided  leased  services to AT&T to
support this service offering.

     AERONAUTICAL  SERVICES.  CMC  provides  satellite   telecommunications
services for aeronautical  applications,  including airline operational and
administrative    communications,    passenger   telephone   service   and,
prospectively,  air traffic  control.  Customers  of CMC for  international
aeronautical   services  include  airline  service  providers,   commercial
airlines, government aircraft and corporate aircraft.

     By an FCC Report and Order issued in 1989, COMSAT was authorized:  (i)
to be the sole  U.S.  provider  of  Inmarsat  space  segment  capacity  for
aeronautical services; (ii) to provide ground segment aeronautical services
in connection with the Inmarsat space segment on a non-exclusive basis; and
(iii) to provide such  aeronautical  services  only to aircraft  engaged in
international flights,  including international flights over U.S. airspace.
Another  entity,  the American Mobile  Satellite  Corporation  (AMSC),  was
designated to be the sole  provider of certain  domestic  aeronautical  and
land  mobile  satellite  services.  In  1995,  CMC  applied  to the FCC for
authority to offer domestic aeronautical services. CMC's request is pending
before the FCC. In 1996, CMC began offering domestic  aeronautical services
on an interim  basis  pursuant to temporary  authority  granted by the FCC,
pending completion of an FCC rulemaking proceeding, which is still ongoing.

                                    10

<PAGE>

     CMC  provides  aeronautical  services  with a data service for cockpit
communications  on commercial  flights under an agreement with Aeronautical
Radio,  Inc.,  an  airline-owned  service  organization.  CMC also provides
aeronautical  voice  services in the  Atlantic  and Pacific  Ocean  Regions
through  its earth  stations at  Southbury,  Connecticut  and Santa  Paula,
California.  There are currently more than 1,400  aircraft  equipped to use
the Inmarsat  aeronautical  system,  equally  split  between voice and data
services.

     A service  agreement with Kokusai Denshin Denwa Co., Ltd.  (KDD),  the
Japanese  signatory  to  Inmarsat,  provides  that CMC may use KDD's ground
earth station  serving the Indian Ocean Region to serve CMC's  aeronautical
customers,  and CMC may serve KDD's customers  flying in the Atlantic Ocean
Region.  Under the  agreement,  CMC and KDD provide  mutual  back-up in the
Pacific Ocean Region for aeronautical customers of both companies.

     A service  agreement  with GTE  Airfone,  Incorporated,  a provider of
air-to-ground  passenger  telephone service using  terrestrial  facilities,
enables  it to extend  its  current  service  to  transoceanic  flights  by
acquiring satellite and ground earth station services from CMC.

     COMSAT has been  selected  by United  Airlines  to  provide  satellite
communications  services for passengers (including telephone,  fax and data
transmission) on approximately 74 United Airlines aircraft, in exchange for
making  available  to United  Airlines  a  financing  facility  of up to $7
million to promote the use of satellite phones on United Airlines aircraft.
The $7  million  facility  will be drawn upon as United  Airlines  installs
seat-back phones on those aircraft.

     CMC also  was  selected  in 1997 to  provide  satellite  communication
services to the  international  fleet of Delta Airlines  (approximately  48
aircraft).  CMC entered into agreements with AT&T Wireless, Inc. to provide
satellite communications to the passenger cabins and with DeltaTel, Inc. to
provide cockpit  communications.  CMC also concluded an agreement with AT&T
to  accept  the use of the  AT&T  calling  card  to  support  this  service
offering.  In  addition,  COMSAT  provides  voice  service  to  Air  Canada
passengers  on 20  aircraft  pursuant  to  an  existing  arrangement  which
commenced in 1994.

     In late 1996, the Federal Aviation  Administration  (FAA) selected CMC
to provide  satellite  and uplink  services for the Wide Area  Augmentation
System  (WAAS).  For  a  further  discussion  of  the  WAAS  contract,  see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations-Outlook."

     LAND MOBILE  SERVICES.  CMC provides  telecommunications  services for
international land mobile applications, using mobile and portable terminals
located outside of the United States.  Customers for these services include
broadcasters,  foreign telecommunications  authorities and U.S. and foreign
corporations and government agencies.


                                    11

     CMC's land mobile services are currently available using transportable
versions of Inmarsat's  Inmarsat-A  and  Inmarsat-B  mobile earth  stations
(telephone,  facsimile,  data,  and  telex),  a  briefcase-size  Inmarsat-M
terminal and a smaller data-only  Inmarsat-C  terminal through CMC's C-Link
service.  C-Link service is a low-cost text messaging  service that permits
smaller vessels and land mobile units to use the global satellite  network.
The  briefcase-size  Inmarsat-M  terminals provide a more portable and less
expensive  telephone service for international  travelers,  the news media,
government  officials  and others  who travel to remote  parts of the world
where reliable communications services are often not available.

     The corporation commenced commercial Planet 1 service in January 1997.
The  Planet 1  terminal  is a six pound,  laptop  computer-sized  satellite
terminal which utilizes the Inmarsat-3  satellites.  This product addresses
the demand for global personal  communications ahead of the availability of
hand-held  satellite services.  All five of the Inmarsat-3  satellites have
been  launched  and placed in  service.  In 1997,  COMSAT  entered  into an
agreement with Embratel permitting Embratel to resell CMC mini-M service in
Brazil. Similar arrangements are being pursued in other countries.

     COMSAT is not  generally  authorized  to provide  U.S.  domestic  land
mobile services.  However, it is providing U.S. domestic service to certain
individual end users under special  temporary  authorities from the FCC. In
1995,  COMSAT applied to the FCC for regular authority to offer land mobile
services  domestically.  In 1996,  COMSAT  applied  to the FCC for  blanket
authority  to  construct  and operate up to 5,000 Planet 1 terminals in the
United States. The FCC has not yet ruled on those applications.

     In November 1997, the FCC issued an order in its "DISCO II" rulemaking
proceeding  addressing,  along with other  issues,  COMSAT's  provision  of
Inmarsat  services  within the United  States.  The FCC ruled that,  before
COMSAT may provide  domestic service within the United States via Inmarsat,
it must first waive its immunity from suit,  including  suit under the U.S.
antitrust  laws,  stemming  from its role as U.S.  signatory  to  Inmarsat.
COMSAT has appealed that ruling. Based in part on this DISCO II policy, the
FCC staff has since denied a COMSAT  request for authority to operate up to
50 Planet 1 terminals domestically. COMSAT has since sought reconsideration
of the staff  decision by the full  Commission  and a partial waiver of the
DISCO II policy.

     In its DISCO II order,  the FCC also stated that it will allow  COMSAT
to provide  international service to and from Inmarsat terminals within the
U.S.,  but  ruled  in  January  1998,  with  regard  to a  COMSAT  Planet 1
application, that COMSAT must first show that the service can be restricted
to calls  originating or terminating  outside of the U.S.  COMSAT has since
filed  an  amendment  to its  underlying  Planet 1  application  containing
proposed  means of providing  such  assurance.  The FCC has not yet ruled o
COMSAT's application as amended.

     INMARSAT.  Inmarsat  is an  81-nation  organization  headquartered  in
London,   England.   It   operates   under   three   agreements:   (1)   an
intergovernmental  convention;  (2) a headquarters  agreement with the U.K.
Government;  and  (3)  an  operating  agreement  signed  by  each  nation's
government or designated  telecommunications entity (signatory).  COMSAT is
the U.S. signatory. It represents the United States in Inmarsat, subject to
instructions  from the  Department of State (in concert with the Department
of Commerce and the FCC) on matters  that may affect the national  interest
and foreign policy of the United States.

                                    12

<PAGE>


     Each  signatory has rights and  obligations  in Inmarsat  analogous to
those of a partner.  Each owns an  investment  share,  makes  proportionate
contributions  to  Inmarsat's  capital  costs,  and receives  proportionate
distributions  of Inmarsat's  space segment  charges after  deductions  for
operating  expenses.  The investment shares are readjusted as of February 1
of each year to approximate  the  Signatories'  respective  portions of the
total  utilization  of the Inmarsat  space  segment for the previous  year.
COMSAT's  investment  share,  the  largest  in  Inmarsat,  was  23.0% as of
December 31, 1997,  which is unchanged  from December 31, 1996. On February
1, 1998, COMSAT's share was reduced to 22.3%.

     At December 31, 1997, total Inmarsat Owners' Equity was  approximately
$978  million.

     The corporation  continues to promote efforts for the privatization of
Inmarsat. For a discussion of the current status of INTELSAT restructuring,
see  "Management's  Discussion  and  Analysis of  Financial  Condition  and
Results of Operations-Outlook."

     The  Inmarsat-3   satellites  are  the  primary  operational  Inmarsat
spacecraft  and are used for  on-demand  services such as Inmarsat A, B, M,
Mini-M,  C, and  Aeronautical.  Some services such as Mini-M and Aero-I are
spot  beam  only  services  and can  only be  supported  on the  Inmarsat-3
satellites. Four Inmarsat-3 satellites are operational (two in the Atlantic
Ocean Region and one in each of the Pacific and Indian  Ocean  Regions) and
one serves as an in orbit spare.

     The   Inmarsat-2   satellites   are  expected  to  provide  full  time
pre-emptible  lease  services  and backup for global  beam  services on the
Inmarsat-3 satellites. Four Inmarsat-2 satellites are in orbit.

     Inmarsat procured the Inmarsat-2 and Inmarsat-3  satellites and launch
services  under  long-term,  multi-satellite  contracts  which provided for
payments by Inmarsat  over the  contract  periods.  The  contracts  for the
construction  of  the  Inmarsat-3  satellites  required   performance-based
incentive payments for each satellite after 60 days of successful  in-orbit
testing and after  successful  emergence of the  spacecraft  from the first
eclipse season.  Additional  incentive payments are made quarterly based on
continuous  satisfactory  operation of the satellite through the end of its
orbital  life.  Incentive  payments were not paid by Inmarsat in connection
with the procurement of the Inmarsat-2 satellites.

     As of  December  31,  1997,  Inmarsat  did not have any  contracts  to
procure additional  satellites.  Inmarsat has purchased an insurance policy
which provides  insurance  coverage after one satellite failure for certain
in-orbit failures for the Inmarsat-3  satellites for 365 days after launch.
Neither Inmarsat nor COMSAT carries  insurance for in-orbit failures beyond
365 days after launch for the Inmarsat-3 satellites. Similarly, there is no
insurance in place for in-orbit failure for the Inmarsat-2 satellites.

     Effective  January 1, 1998,  the  corporation  changed its  accounting
policy with respect to the cost of series  satellites  lost at launch or in
orbit and its  accounting  policy  with  respect to  satellite  performance
incentives  paid  to  manufacturers.   See  ""Management's  Discussion  and
Analysis of Financial Condition and Results of Operations-Outlook."


                                    13

<PAGE>


     Inmarsat  generally offers its customers  (including COMSAT) satellite
capacity on demand  generally  under terms that  require  payments on a per
minute  basis.  In  contrast  to  INTELSAT,  Inmarsat  has  relatively  few
long-term commitments for satellite capacity.

     ICO. In late 1996 and early 1997, the  corporation  reduced its direct
investment  in ICO  Global  Communications  (Holdings)  Limited  (ICO)  and
presently  owns  1.7%.  See  Note  5  to  the  financial  statements.   The
corporation  also  continues  to hold an indirect  share of ICO through its
ownership  interest  in  Inmarsat,  which is also an ICO  shareholder.  The
corporation  is evaluating  its plans with respect to  distribution  of ICO
products  and  services  and will  continue  to assess  whether  its direct
ownership i properly aligned with those plans.

     ICO was formed to provide hand-held satellite  communications services
outside of the Inmarsat  organization to allow a more commercial focus than
the current  Inmarsat  system.  The other current  major  investors in ICO,
besides the  Corporation  and Inmarsat,  include  Inmarsat  signatories and
Hughes  Communications,  Inc. (Hughes) and TRW, Inc., which are expected to
compete  with the  corporation  as service  providers in the U.S. and other
markets.  For a discussion  of the proposed  ICO  satellite  system and the
corporation's  investment in ICO, see "Management's Discussion and Analysis
of Financial Condition and Results of  Operations-Outlook"  and Notes 8 and
10 to the financial statements.

     On May 1, 1995, COMSAT filed an application with the FCC for authority
to  participate  in  Inmarsat's  procurement  of space segment from ICO for
specialized  (non-handheld)  communications  services. In that application,
COMSAT also sought an FCC ruling that ICO had been structured in compliance
with the requirements for COMSAT's  participation in ICO set out in a prior
FCC  ruling.   The   application   is  being  opposed  by  certain  of  the
corporation's competitors. The FCC has not acted on that application.

     In 1997,  COMSAT concluded  agreements with ICO to construct,  operate
and interconnect a "satellite  access node" (SAN) in Brewster,  Washington.
It is contemplated that the Brewster SAN will become part of ICO's backbone
network.

     COMPETITION.  Under the Inmarsat Act,  COMSAT is the  designated  U.S.
signatory  to the  Inmarsat  Operating  Agreement,  and is  the  sole  U.S.
operating  entity and  investor in the  Inmarsat  system.  CMC competes for
maritime,  land mobile and aeronautical  communications business with other
Inmarsat  Signatories  operating  land earth  stations  and with IDB Mobile
Communications,  Inc. (IDB), another U.S. land earth station operator.  IDB
provides  maritime,  land mobile and aeronautical  services through its own
U.S. land earth stations,  using Inmarsat  satellite capacity obtained from
CMC, as well as through certain foreign earth stations.

     In October 1997, IDB informed COMSAT that it was no longer  purchasing
Inmarsat  satellite  capacity  used by its U.S.  land earth  stations  from
COMSAT,  but was instead  purchasing that capacity from another  signatory.
COMSAT  believes  that IDB is  required,  under  the  terms of its  service
contract with COMSAT,  U.S. law and the Inmarsat  Operating  Agreement,  to
purchase that capacity  from COMSAT.  After  attempts to resolve this issue
failed,  COMSAT in January 1998 filed a lawsuit against IDB seeking damages
for breach of contract in the United States District Court for the Southern
District  of  Maryland.  In  February  1998,  IDB  filed a  petition  for a

  
                                    14
<PAGE>


declaratory  ruling asking the FCC to rule that operators of U.S.  Inmarsat
Land earth stations may purchase Inmarsat  satellite  capacity from foreign
signatories and a motion to dismiss or stay COMSAT's  lawsuit until the FCC
rules.  COMSAT has filed an opposition to both aspects of IDB's motion. The
court has not yet ruled.

     In addition,  CMC competes with American Mobile Satellite  Corporation
(AMSC), which launched its own satellite in 1995 to offer U.S. domestic and
international  mobile  satellite  services.  CMC also competes for maritime
communications  business  with  domestic  and  international  operators  of
cellular radio services,  high frequency radio services,  mobile satellites
and C-band and Ku-band satellites, and in the future is expected to compete
with the  FCC-licensed  low-earth-orbit  ("Big Leo")  satellite  systems of
Iridium and GlobalStar and the medium-earth-orbit  satellite system of ICO.
Operators  of  C-band  satellites  have  been  successful  in  capturing  a
significant portion of the maritime  communications  business with the U.S.
Navy and cruise ships.  These  competitive  forces have and are expected to
continue to exert downward  pressure on CMC's pricing for services provided
through the Inmarsat system.

     FCC  decisions  also may  significantly  affect  the  competition  for
products and services  offered by CMC. In November 1993, the FCC authorized
AT&T to provide shore-to-ship Inmarsat service under an agreement with CMC.
In  December  1993,  AT&T  filed  a new  application  to  provide  "branded
end-to-end"  Standard-A  mobile  satellite  service  in  the  ship-to-shore
direction,  which  COMSAT  opposed.  In early  1996,  AT&T was  granted FCC
authorization  to offer such service.  In June 1996, CMC and AT&T concluded
an  Interconnection  and Service  Agreement to address  interconnection  of
facilities and settlement issues.

     In December  1994,  IDB filed two  applications  seeking  authority to
provide  Inmarsat-M  and  Inmarsat-B  services to maritime  and land mobile
users through foreign land earth stations in the shore-to-ship direction in
the Atlantic and Pacific Ocean regions.  In that proceeding,  IDB contended
that the  Inmarsat  Act allows  U.S.  carriers to use  Inmarsat  land earth
stations and space segment obtained from foreign  Inmarsat  Signatories for
U.S.-originating  traffic,  a position  COMSAT  opposes.  IDB  withdrew  it
applications  in July 1995.  In August  1995,  however,  Cruisephone  filed
applications, which are being opposed by COMSAT, that raise similar issues.
In January 1997, IDB filed another  application,  which COMSAT has opposed,
seeking authority to provide Inmarsat-M and -B services (including carriage
of  U.S.-originating  fixed-to-mobile  traffic)  through foreign land earth
stations  using   Inmarsat   satellite   capacity   procured  from  foreign
signatories. The FCC has not yet ruled on these applications.

     In March 1993, the FCC granted COMSAT a waiver that would allow COMSAT
to provide  equipment,  software  and  value-added  services  to  customers
directly  through CMC, rather than through a separate  subsidiary,  thereby
avoiding  substantial  duplication of personnel and other costs, subject to
COMSAT's  establishing certain  non-structural  safeguards.  To satisfy the
FCC's conditions, COMSAT filed a proposed cost allocation manual and a plan
for implementing  certain  non-accounting  safeguards requested by the FCC.
The FCC approved  cost  allocation  manual in July 1995.  The FCC has since
approved the second  compliance  filing,  but has  conditioned the waiver's
effectiveness on COMSAT's submission,  and the FCC's approval, of a revised
cost allocation manual. COMSAT submitted the revised cost allocation manual
in January 1998. The FCC has not yet acted on that filing.

                                    15

<PAGE>


     In 1995,  COMSAT  petitioned the FCC for  authorization to provide the
same kinds of  value-added  services  to its  aeronautical  and land mobile
customers.  The FCC granted this petition in 1996,  subject to FCC approval
of non-structural safeguards -- which approval was granted in 1997. The FCC
has made the effectiveness of this waiver  conditional upon its approval of
COMSAT's revised cost allocation manual.

     REVENUES. Approximately 30% of the corporation's consolidated revenues
in 1997 were derived from CMC (compared to 30% in 1996 and 36% in 1995). No
single  customer  of CMC  provided  more  than  10%  of  the  corporation's
consolidated revenues in 1997.


                             NETWORK SERVICES

COMSAT INTERNATIONAL

     COMSAT   International   (CI)   operates   an   integrated   group  of
telecommunications  companies  that are engaged  principally  in  providing
individualized  digital network  solutions to business clients and carriers
in selected  markets.  CI also is actively  engaged in the  development  of
prospective   international   telecommunications   opportunities  that  are
consistent  with  its  digital  networking  strategy.   CI's  existing  and
prospective  companies  typically  are and will be located in those rapidly
growing  markets  where a  significant  number of CI's existing or targeted
clients are located (or where they intend to locate).

     As of December 31, 1997,  CI operated 15  companies  worldwide.  These
companies are located in Latin  America,  Asia and Europe.  CI's  companies
generally are wholly- or  majority-owned,  with the exception of COMSAT Max
Limited,  CI's company operating in India, and Viatel,  Inc. (Viatel),  the
European  facilities-based  carrier and call-back company.  At December 31,
1997,  CI  beneficially  owned 50% and 9.5%,  respectively,  of COMSAT  Max
Limited  and  Viatel,  respectively.  CI's  clients  are  typically  local,
indigenous  large  and  medium-sized  corporations,  national  branches  of
multinational  corporations  and  major  telecommunications   carriers  and
consortia.

     CI continued to develop new opportunities around the world in 1997. In
particular,  CI  expanded  its  activities  in Latin  America  through  the
acquisition  of  IntelComRed  S.A. de C.V.,  a Mexican  satellite  services
company,  and renamed it COMSAT Mexico S.A. de C.V.  Primarily  through the
completion of a statutory  merger under Delaware law, CI also increased its
ownership interest and operating control of BelCom,  Inc. (BelCom) to 100%.
BelCom  currently  provides  telecommunications  services  in  the  Russian
Federation  and certain  countries of the Newly  Independent  States (NIS),
including Kazakhstan, Uzbekistan and Turkmenistan. In addition, CI sold its
19.66% interest in Philippine Global  Communications,  Inc.  (PhilCom) (see
Notes 3 and 5 to the financial statements) in January 1997.

     CI's companies  operate in numerous and diverse markets,  as reflected
in the table set forth below.  Consequently,  the level of  competition  in
these  countries  varies  considerably.  In some  countries  there  is full
competition,  and in others  competition is limited by law. The competitive
conditions  faced by each company are the result of differing  and changing
regulatory policies and economic  conditions.  In those countries that have
not yet undergone a substantial  liberalization of their telecommunications

                                    16

laws,  CI's principal  competitor is typically the local Postal,  Telegraph
and  Telephone  administration  (PTT),  together  with a limited  number of
companies that provide telecommunications services similar to those offered
by CI. In countries that have liberalized their telecommunications laws, CI
typically faces greater competition than in less liberalized markets.

customers  worldwide.   COMSAT  Laboratories  also  designs,  develops  and
licenses  communications  products for access,  compression  and networking
applications  as  well  as  software  for  satellite  system  planning  and
management. COMSAT Laboratories also licenses new technology it develops to
other companies for commercialization.

     Customers  include U.S. and foreign  government  agencies,  commercial
entities,  INTELSAT and Inmarsat. In addition, COMSAT Laboratories conducts
research and  development on a broad range of  telecommunications  devices,
subsystems, transmission systems, technologies and techniques in support of
other COMSAT businesses.

                                    17

<PAGE>


     On-going  contracts  being  performed in 1997  include:  a contract to
design,  manufacture  and deliver  S-band mobile  satellite  communications
equipment;   a  contract  with  AT&T  to  deliver  second  generation  TDMA
terminals;  a contract  with  Ericsson to design and develop the HPN ICONET
ground facilities subsystems; contracts with INTELSAT to design STRIP 7 and
develop a software system for generating  INTELSAT TDMA burst time plans; a
contract  with NASA to provide  operation and  maintenance  support for the
ACTS (Advanced Communications  Technology Satellite) program; and a variety
of  technical  consulting  contracts  for  INTELSAT,   Inmarsat  and  other
governmental and private industry customers.

     COMSAT Laboratories won external contracts with a total value of $29.7
million in 1997.  Major new contracts  awarded or begun in 1997 include:  a
contract  with  Ericsson  to  design  and  develop  the HPN  ICONET  ground
facilities  subsystem for ICO; a contract with Lockheed Martin for the ACES
In-Orbit-Test  System;  a contract  with Iridium for its second  generation
system;  a contract with  Raytheon for ATM  satellite  link adapter for the
Midas program.

     Revenue from  external  customers  was $24.6 million in 1997 and $32.3
million in 1996.  COMSAT  Laboratories  support of other  COMSAT  divisions
totaled  $11.8  million in 1997 and $11.4  million in 1996. At December 31,
1997,  COMSAT  Laboratories'  backlog of orders totaled $28.3  million,  as
compared to $21.3 million at December 31, 1996.

     COMSAT Laboratories incurred research and development  expenditures of
$3.7  million  in  1997,  a  decrease  of $2.6  million  from  1996.  These
expenditures  were  largely  attributed  to the  development  of its  video
compression, asynchronous transfer mode (ATM) and software products. COMSAT
Laboratories  expects R&D  expenses to increase in the future as it pursues
additional commercial activities.

GOVERNMENT PROGRAMS

     Network  Services'   government  and  commercial  programs  businesses
consist of the operations of COMSAT  Government  Services,  Inc. (CGSI) and
COMSAT General Corporation,  both of which are wholly-owned subsidiaries of
the corporation.

     CGSI was incorporated in 1997 to focus more directly on the government
satellite market and develop other  government  service  applications.  The
core  business  for  CGSI  is  the  Commercial   Satellite   Communications
Initiative (CSCI) program which is a contract with the Defense  Information
Systems  Agency  (DISA) to  provide  commercial  satellite  services.  CGSI
provides  satellite  bandwidth,  operates two bandwidth  management centers
currently,  and  provides  satellite  engineering  services  under the CSCI
contract.

     COMSAT  General  provides  satellite  earth  station  service  through
facilities  located in Clarksburg,  Maryland,  Santa Paula,  California and
Southbury,  Connecticut.  COMSAT  General  operates  antennas,  a satellite
control facility,  and high speed fiber interconnects to telecommunications
carriers and Internet  service  providers.  COMSAT General services include
transmission  and  reception   capability  to  INTELSAT  and  non  INTELSAT
satellites for voice, data, Internet and video broadcasts.

                                    18

<PAGE>


     COMSAT  General  also  provides  satellite  operation  service for the
Marisat  and  Comstar  satellites,  which  includes  tracking,   telemetry,
command,  and  maintenance of these assets.  In addition to operating these
satellites,  COMSAT  General  also  leases  transponder  capacity  on those
satellites.  COMSAT  General  provides  services  to  both  commercial  and
government customers.

                          DISCONTINUED OPERATIONS

ASCENT

     During 1995, the corporation  incorporated  and transferred all of its
entertainment  assets  to  COMSAT  Entertainment  Group,  Inc.,  which  was
subsequently renamed Ascent Entertainment Group, Inc. (Ascent).  An initial
public  offering of Ascent's  common stock was completed in December  1995.
Ascent's  common  stock is traded on the Nasdaq  National  Market under the
symbol  "GOAL."  Following the offering,  the  corporation  owned 80.67% of
Ascent's  common stock.  During the second quarter of 1997, the corporation
began  accounting  for  the  operations  of  substantially  all of  CRSI as
discontinued  operations  See  Note  2 to  the  financial  statements.  The
corporation   distributed  its  80.67%  ownership  interest  in  Ascent  to
shareholders on June 27, 1997.

     Ascent's  principal business is providing  pay-per-view  entertainment
and information services through its 57 percent-owned subsidiary On Command
Corporation. In addition, Ascent is involved in other entertainment-related
businesses  including ownership and operation of the NBA Denver Nuggets and
NHL Colorado  Avalanche,  development  and  management  of The Pepsi Center
through Ascent Arena Company, and Beacon  Communications,  a motion picture
and television production company.

COMSAT RSI

     COMSAT  RSI,  Inc.  (CRSI) was formed in 1994 in  connection  with the
acquisition  by the  corporation  of Radiation  Systems,  Inc.  (RSI).  The
corporation  combined  RSI with  certain of its then  existing  antenna and
wireless networks product and system  integration  operations to form CRSI.
During the second quarter of 1997, the corporation began accounting for the
operations of  substantially  all of CRSI as discontinued  operations.  See
Note 2 to the financial statements.

     In March 1998, the corporation entered into a stock purchase agreement
to  sell  substantially  all of  CRSI.  See  "Management's  Discussion  and
Analysis of Financial  Condition  and Results of  Operations-Outlook."  The
sale of  substantially  all of the assets and  liabilities of JEFA Wireless
Systems,  a subsidiary of CRSI, was completed in a separate  transaction in
February  1998.  Also  included  as  part  of  discontinued  operations  is
Electromechanical  System,  Inc. (EMS), a wholly-owned  subsidiary of CRSI,
and an equity  ownership  interest  in  Plexsys  International  Corporation
(Plexsys),  which are being  retained  by COMSAT per the terms of the stock
purchase  agreement,  pending  evaluation  of available  alternatives.  The
long-term contract for construction of a radio telescope in Greenbank, West
Virginia also is to be retained by the  corporation in connection  with the
stock purchase  agreement.  The Labs sector of the Network Services segment
and the  Government  Programs  sector of  Satellite  Services  now includes
certain non-manufacturing, telecommunications contracts and businesses that
were  previously  reported  as  part of  CRSI  in the  Technology  Services
segment.

                                    19

<PAGE>


     CRSI designs,  manufactures and integrates earth stations,  as well as
wireless and advanced  antenna  systems.  CRSI has three operating  groups:
Advanced Systems, Communication Systems and Wireless Networks. These groups
include 10 business  units, 9 of which are  vertically  integrated to serve
global  telecommunications  markets.  The remaining  unit serves the global
machine tool market.  CRSI's customers  include the U.S.  Government,  U.S.
Government prime  contractors,  foreign  governments,  domestic and foreign
telecommunication   service  providers,   broadcast  and  cable  television
operators, and a wide variety of other commercial customers.

     CRSI's  manufactured  products  include  a broad  range  of  parabolic
antennas  and  line-of-sight  microwave  antennas,  cellular  and  personal
communication  system  (PCS)  antennas,   satellite  frequency  converters,
microwave  components,   Ultra-Small  Aperture  Terminal  (USAT)  and  VSAT
equipment,  cellular switch and base station radio equipment, servo control
systems, vehicle-mounted mobile antennas, multiplexers, antenna monitor and
control systems,  antenna positioning systems,  tactical military antennas,
air traffic control  antennas,  radar antennas,  radio telescope  antennas,
tactical masts,  monopoles,  towers,  and optical measuring  devices.  CRSI
designs, integrates,  installs and tests large-scale wireless and satellite
ground systems,  private VSAT networks,  video distribution  networks,  and
network  control  systems.  In  addition,  CRSI  provides  turnkey  gateway
antennas  and network  control  systems for  regional  and global fixed and
mobile satellite systems.

     CRSI  competes  with  major  companies  around  the  world in  several
telecommunications markets. Major competitors in the communications systems
market  include  Scientific  Atlanta,  Inc.;  California  Microwave,  Inc.;
Globecomm Systems,  Inc.;  Alcatel N.V.; Miteq,  Inc.; LNR  Communications,
Inc.; SSE Telecom,  Inc.; NEC; Harris Corporation;  and Mitsubishi.  In the
wireless  networks  market,   competitors  include  GM  Hughes  Electronics
Corporation;   Gilat  Satellite   Networks  Ltd.;   ViaSat,   Inc.;  Andrew
Corporation;   Kathrein;  Cellwave;  Allgon;  Gabriel  Electronics,   Inc.;
Ericsson Radio Systems AB; Northern  Telecom  Limited;  Stanilite;  Celcore
(recently acquired by DSC Communications  Corp.); Alcatel NV; STM Wireless,
Inc.; EMS Technologies,  Inc.; and Allen Telecom, Inc. The advanced systems
markets  competition  includes  Datron  Systems,  Inc.; TIW Systems,  Inc.;
Electrospace Systems, Inc.; Signal Processors,  Ltd.; Marconi Radar Systems
Limited; Cosser Electronics Limited (Raytheon);  Tech-Sym Corporation;  and
Vertex   Communications   Corporation.   Certain   companies  like  Hughes,
Scientific  Atlanta,  California  Microwave,  Harris,  Alcatel  and  Andrew
Corporation compete in most of CRSI's markets.  Many of these companies are
considerably  larger and have greater financial resources than CRSI. In all
market  areas,  CRSI competes on the basis of price,  performance,  on-time
delivery, reliability and customer support.

     As part of the stock purchase agreement, the corporation has agreed to
retain the  long-term  contract for the  completion  of the 100 meter radio
telescope at Green Bank,  West Virginia.  COMSAT or a subsidiary  also will
retain the CRSI  employees  at the site and assume the  contracts  with two
unions that provide on-site labor. CRSI will provide the surface panels and
certain other services related to completion of the servo-drive  system for
the telescope under a separate  subcontract.  COMSAT is in negotiation with
Associated  Universities  Incorporated,  which  operates the National Radio
Astronomy Observatory at Green Bank under a Co-operative Agreement with the
National  Science  Foundation,  for novating of the  original  contract for
construction  of  the  telescope  from  CRSI  to  COMSAT.  Novation  of the
Greenbank  contract is a condition to the  purchaser's  obligation to close
under the stock  purchase  agreement.  CRSI's  $29  million  claim for work

                                    20

<PAGE>


performed under and relating to the Greenbank contract,  which is currently
in  arbitration,  also will be assigned to COMSAT in connection  with stock
purchase agreement.  There can be no assurance that the corporation will be
successful in collecting all or any portion of the claim.

     Electromechanical  Systems,  Inc.  (EMS)  designs,   manufactures  and
installs  multi-axis  positioning  control units  (pedestals) for precision
tracking   and   pointing  for  air  traffic   control,   weather,   radar,
communication  and  surveillance  equipment.  EMS also provides  repair and
restoration  service for various antenna pedestals for its customers.  More
than  90% of  EMS's  current  business  is  with  military  and  government
customers, nearly all in the U.S.

     CRSI also owns  approximately 53% of the outstanding equity securities
of Plexsys International  Corporation (Plexsys).  Plexsys provides turn-key
cellular and wireless local loop systems  primarily  targeted at thin-route
applications in rural or developing markets and manufactures  switching and
base  station  equipment.  Most of Plexsys'  business  is in  international
markets.  In February  and March 1998,  Plexsys  substantially  reduced its
operations  and  laid  off  most  of its  staff.  The  corporation  doe not
anticipate  that it will  recover  its  investment  in  Plexsys  or certain
amounts owed it by Plexsys.  The corporation  believes that the reserves it
has  established  for the  disposition  of CRSI  generally  are adequate to
absorb  any  losses  that are  likely to be  incurred  in  connection  with
Plexsys. There can be no assurance,  however, that additional reserves will
not be required.

                                INVESTMENTS

         The  corporation's  investments  are  discussed  at  Note 5 to the
financial statements.

ITEM 2.   PROPERTIES

COMSAT PROPERTIES

     At  year  end  1997,  the  headquarters  of the  corporation  and  the
headquarters  of the  Satellite  Services  segment and CI were located in a
building in Bethesda, Maryland, which the corporation leases from a limited
partnership  in which  it  holds a 50%  interest,  primarily  as a  limited
partner.  The  managing  general  partner  also owns a 50%  interest in the
partnership. An affiliate of the managing general partner owns the building
site and has  leased  this site to the  partnership.  The  corporation  has
entered into a 15-year lease with the partnership for the new building (see
Note 8 to the financial statements).

     In  1997,  the  corporation  sold  the  office  buildings  and land at
Clarksburg, Maryland that serve as the headquarters of COMSAT Laboratories,
as well as offices for certain  operations of CRSI. The corporation  leased
back the office  buildings  for a ten-year  lease  term.  See Note 4 to the
financial statements.

                                    21

<PAGE>


     The  corporation  also owns two  manufacturing  facilities  in Dulles,
Virginia, one of which serves as the headquarters of CRSI, and land located
nearby  that is  used as an  antenna  test  range  by  CRSI.  Further,  the
corporation owns or leases 10 other properties in the United States, leases
two  properties  in  England  and a sales  office in  Beijing,  China.  The
properties  owned by CRSI are to be transferred  upon  consummation  of the
proposed sale of CRSI and the purchaser  will assume the leases for the CRS
leased  properties  in  accordance  with the  terms of the  stock  purchase
agreement.

     COMSAT  General owns 86.3% of the MARISAT Joint  Venture,  which still
operates  the MARISAT F-2,  one of the three  satellites  launched in 1976,
with  capacity  leased  to the U.S.  Navy and  Fugro  N.V.,  a  Netherlands
company.  The MARISAT  F-1 and F-3 ceased  commercial  operations  in 1996.
COMSAT  General  owns the COMSTAR  D-4  satellite  (launched  in 1981) with
capacity leased to CMC and the U.S. Navy.

     The corporation leases earth stations in Turkey and Malaysia, and owns
earth stations at Santa Paula,  California and Southbury,  Connecticut that
are used by CMC to provide mobile  communications  services. A leased earth
station in Fucino,  Italy along with the California and  Connecticut  earth
stations are used by CRSI to provide TT&C services.  The  corporation  owns
earth stations at Clarksburg, Maryland and Paumalu, Hawaii that are used by
CWS  to  provide  TT&C  services  to  INTELSAT.  The  corporation  owns  an
additional  earth station at Clarksburg,  Maryland which is used by Network
Services'  Government  Programs to house its Satellite Control and Teleport
Facilities  as  well  as the  Bandwidth  Management  Center  for  the  U.S.
Government CSCI Program.

     CI leases  facilities  in each of the  countries in which it operates.
See "General  Information - Network Services - COMSAT  International" above
for a listing of the countries in which CI operates.

     The corporation's  properties are believed to be suitable and adequate
for the corporation's business operations.

INTELSAT SATELLITES

     The  corporation's  property  accounts include CWS's pro-rata share of
INTELSAT  satellites.  The  INTELSAT  satellites  currently  used and under
construction are described  below.  Some of these satellites are planned to
be transferred to a separate entity as a result of INTELSAT  restructuring.
For a  discussion  of the  current  status of INTELSAT  restructuring,  see
"Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Outlook."

     There are seven INTELSAT V and VA satellites  continuing to operate in
the INTELSAT  system.  All these  satellites  have reached the end of their
design lives and are operating in an inclined orbit. Their capacities range
from 15,000 to 17,000 voice  circuits or 51 to 57  television  channels (or
some combination of each depending on the  configuration of the satellite).
The satellites were built by a predecessor to Space Systems/Loral.

                                    22

<PAGE>


     The INTELSAT VI series  consists of five  satellites,  constructed  by
Hughes Aircraft Company, a subsidiary of General Motors Corporation.  These
satellites  have an average  capacity of at least 24,000 bearer circuits or
87 television channels.  The INTELSAT VI satellites,  the last of which was
launched on October  1991,  currently  provide  primarily  backbone  public
switched network (PSN) services in the Atlantic and Indian Ocean regions.

     The INTELSAT-K  satellite,  constructed by General Electric  Technical
Services Company,  Inc., which was subsequently acquired by Lockheed Martin
Corporation  and launched in 1992, has an average  capacity of 7,000 bearer
circuits or 32 television channels. The INTELSAT-K satellite provides video
transponder leases to European and North American customers.

     The  INTELSAT VII series  consists of six  satellites  constructed  by
Space Systems/Loral.  These satellites have an average capacity of at least
17,050 bearer circuits or 62 television channels (or a capacity of 62 36MHz
units with a typical minimum power range of 29 to 34.5 decibels relative to
one watt (DBW) at C-band and 44 DBW at Ku-band  depending on the beam). The
last  INTELSAT VII satellite  was launched in June 1996.  These  satellites
were  designed  to  replace  the V/VA  satellites.  They  provide  improved
utilization and flexibility,  with improved radio frequency power, enhanced
Ku-band  coverage and increased  C-band  connectivity  compared to the V/VA
satellites.

     The INTELSAT VIIA series,  also  constructed  by Space  Systems/Loral,
consists of two  satellites  having an average  capacity of at least 19,250
bearer circuits or 70 television  channels (or a capacity of 70 36MHz units
with a typical minimum power range of 29 to 36 DBW at C-band and 42.7 to 45
DBW  at  Ku-band  depending  on  the  beam).  Of the  three  INTELSAT  VIIA
satellites constructed,  the first INTELSAT VIIA satellite was successfully
launched in May 1995; the launch of the second VIIA, in February 1996 was a
failure (see Note 4 to the  financial  statements);  and the third VIIA was
successfully   launched  in  March  1996.  These   satellites   provide  an
enhancement over the VII satellites to meet increased demand for high power
Ku-band capacity.  New  cross-strapped  connectivity from Ku-band to C-band
allows the  provision of satellite  news  gathering  (SNG)  service using a
roving Ku-band Spot Beam in the uplink.

     The INTELSAT VIII series  consists of four  satellites  constructed by
Lockheed Martin  Corporation.  These satellites have an average capacity of
21,000 bearer circuits or 76 television channels (or a capacity of 76 36MHz
units with a typical  power range of 29 to 34.5 DBW at C-band and 44 DBW at
Ku-band  depending on the beam).  All four  INTELSAT VIII  satellites  were
successfully  launched in 1997. They were designed  primarily to complement
the INTELSAT VI satellites and meet growing demand for C-band services. The
INTELSAT  VIII series  satellites  provide new  television  broadcast  mode
capability with  simultaneous up link from the Northeast zone beam and down
link from three West zone beams.  The INTELSAT VIII series  satellites also
provide  expanded SNG service with the  capability  to cross connect any of
the Ku-band spot beams to any of the global beams in certain transponders.

     The INTELSAT VIIIA series  consists of two  satellites  constructed by
Lockheed Martin  Corporation.  These satellites have an average capacity of
at least 11,600 bearer circuits or 38 television channels (or a capacity of
42 36MHz  units with a power  range of 39.7 to 42 DBW at C-band and 50.4 to
51.7 DBW at Ku-band  depending on the bean).  The INTELSAT  VIIIA (F-6) was
successfully  launched  in  February  1998.  The  INTELSAT  VIIIA  (F-5) is
scheduled  for launch later in 1998.  The  INTELSAT  VIIIA  satellites  are

                                    23

designed for users requiring high power together with a wide coverage areas
in C-band for the  provision of services such as video,  VSAT  applications
and PSN. They use complex  state-of-the-art  antenna  technology to provide
improved coverage of land areas of North and South America.

     COMSAT has applied to the FCC for  authorization to participate in the
procurement of the K-TV satellite.  This spacecraft is being constructed by
Matra  Marconi  Space and has a capacity  of 30 36MHz  transponders  with a
typical minimum range of 36 to 52 DBW depending on the beam. It is expected
that the  satellite  will be  launched  in the first  quarter of 1999.  The
satellite was designed to provide high power Ku-band capacity  specifically
for direct-to-home television service, and VSAT network applications,  such
as  data   distribution  and  contribution,   including   INTERNET/INTRANET
networks.  The K-TV  satellite  will provide  coverage over areas of India,
China and Indonesia/Malaysia.

     COMSAT has applied to the FCC for  authorization to participate in the
procurement of up to five INTELSAT IX satellites.  As of December 31, 1997,
procurement  of four  satellites had been approved by the INTELSAT Board of
Governors.  These spacecraft are to be built by Space Systems/Loral and are
intended to replace the INTELSAT VI  satellites in the years 2000 and 2001.
The INTELSAT IX satellites  are expected to have an average  capacity of 98
36MHz  transponders  with a  typical  minimum  power  range of 31 to 47 DBW
depending  on  the  beam.  The  satellites  will  provide   primarily  high
connectivity  backbone  PSN  services  in the  Atlantic  and  Indian  Ocean
regions.  The INTELSAT IX satellites  will be INTELSAT's  largest  capacity
satellite with advanced communications and RF performance.


     The  corporation  has  purchased  insurance  to cover the  launch  and
subsequent  in-orbit  testing of the  INTELSAT  VIII and VIIIA  satellites.
Partial loss in-orbit  insurance  for the remaining  four INTELSAT VIII and
VIIIA  satellites  was  purchased  for the  first  365 days  after  launch.
Effective  January 1, 1998, the corporation  changed its accounting  policy
with  respect to the cost of series  satellites  lost at launch or in orbit
and its accounting policy with respect to satellite performance  incentives
paid to  manufacturers.  See  ""Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations-Outlook."

INMARSAT SATELLITES

     The  corporation's  property  accounts include CMC's PRO-RATA share of
Inmarsat  satellites.  The  Inmarsat  satellites  currently  used and under
construction are described below.

     The   second-generation   Inmarsat  satellite  system,  known  as  the
Inmarsat-2   series,   consists  of  four  satellites   constructed  by  an
international  consortium led by British  Aerospace  Dynamics  Corporation.
These satellites are now used primarily for leases and backup capacity. The
Inmarsat-2  satellites  are  expected  to be moved,  depending  on  traffic
demand,  to new  orbital  locations  where  they  will  provide  full  time
pre-emptible lease services.  The Inmarsat-2 series satellites also provide
backup for global beam services on the Inmarsat-3 satellites. Some services
such as Mini-M  and  Aero-I  are spot beam  only  services  and can only be
supported on the Inmarsat-3 satellites.


                                    24

<PAGE>


     The   third-generation   Inmarsat  satellite  system,   known  as  the
Inmarsat-3  series,  consists of five  satellites  constructed  by Lockheed
Martin Astro Space. These satellites use spot-beam technology, which allows
reuse of the scarce  frequency  resources  allocated  for mobile  satellite
communications.  The  Inmarsat-3s  are about eight times more powerful than
the  Inmarsat-2   series.  All  five  of  these  satellites  were  launched
successfully. Four of the Inmarsat-3 satellites are the primary operational
Inmarsat spacecraft and are used for on-demand services such as Inmarsat A,
B, M, Mini-M, C, and Aero. The fifth Inmarsat-3  satellite is planned to be
used  primarily for leases and backup  capacity.  Inmarsat has purchased an
insurance  policy  for  365  day  in-orbit  coverage  after  launch.  For a
discussion  of  financing  arrangements  related to the  Inmarsat-2  and -3
satellites,  see Note 6 to the financial  statements.  Effective January 1,
1998, the  corporation  changed its  accounting  policy with respect to the
cost of series  satellites  lost at  launch or in orbit and its  accounting
policy  with  respect  to   satellite   performance   incentives   paid  to
manufacturers.  See  ""Management's  Discussion  and  Analysis of Financial
Condition and Results of Operations-Outlook."

ITEM 3.   LEGAL PROCEEDINGS

     Neither COMSAT nor any of its  subsidiaries is a party to, and none of
their property is the subject of, material pending legal  proceedings,  and
no  such   proceedings   are  known  to  be  contemplated  by  governmental
authorities,  except  for the  matters  described  in  Notes 8 and 9 to the
financial statements and as discussed below.

     In 1995, the corporation  entered into a five-year agreement with News
Corporation to provide satellite services beginning in 1996. In March 1996,
News Corporation rescinded this agreement.  The corporation has commenced a
lawsuit  against  News  Corporation  and other  parties to recover  damages
arising out of News  Corporation's  breach of  obligation  to COMSAT.  News
Corporation  has  asserted  a counter  claim for  return of the  deposit it
originally paid.

     In October 1997, IDB informed COMSAT that it was no longer  purchasing
Inmarsat  satellite  capacity  used by its U.S.  land earth  stations  from
COMSAT,  but was instead  purchasing that capacity from another  signatory.
COMSAT  believes  that IDB is  required,  under  the  terms of its  service
contract with COMSAT,  U.S. law and the Inmarsat  Operating  Agreement,  to
purchase that capacity  from COMSAT.  After  attempts to resolve this issue
failed,  COMSAT in January 1998 filed a lawsuit against IDB seeking damages
for breach of contract in the United States District Court for the Southern
District  of  Maryland.  In  February  1998,  IDB  filed a  petition  for a
declaratory  ruling asking the FCC to rule that operators of U.S.  Inmarsat
land earth stations may purchase Inmarsat  satellite  capacity from foreign
signatories and a motion to dismiss or stay COMSAT's  lawsuit until the FCC
rules.  COMSAT has filed an opposition to both aspects of IDB's motion. The
court has not yet ruled.

     COMSAT  and its  subsidiaries  are a party  to  various  lawsuits  and
arbitration  proceedings  and are subject to various  claims and inquiries,
which generally are incidental to the ordinary course of its business.  The
outcome of legal proceedings  cannot be predicted with certainty.  Based on
currently available information,  however, management does not believe that
the  outcome  of  any  matter  which  is  pending  or  threatened,   either
individually or in the aggregate,  will have a materially  adverse effect o
the  consolidated   financial   condition  of  the  corporation  but  could
materially  affect  consolidated  results of  operations in a given year or
quarter.

ITEM 7:     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

                           ANALYSIS OF OPERATIONS

CONSOLIDATED OPERATIONS

     During the second quarter of 1997, the  corporation  began  accounting
for the operations of both Ascent  Entertainment  Group,  Inc. (Ascent) and
substantially  all of COMSAT RSI, Inc. (CRSI) as  discontinued  operations.
The  consolidated  financial  statements have been restated for all periods
presented to reflect the results of operations and net assets of Ascent and
CRSI as discontinued operations.

CONTINUING OPERATIONS

     Consolidated  revenues  from  continuing  operations in 1997 were $563
million,  $18 million higher than the previous year.  This  improvement was
the result of a 19% increase in Network  Services  segment  revenues  which
was,  in part,  offset  by a 1%  decrease  in  Satellite  Services  segment
revenues.  Consolidated revenues for 1996 were $545 million, an increase of
$37 million as compared to 1995.  Network Services segment revenues in 1996
were 58% higher than 1995, while Satellite  Services revenues were slightly
below the previous year.

     Operating income from continuing  operations for 1997 was $82 million,
as  compared  to $107  million  for 1996.  The lower  operating  income was
primarily the result of lower  operating  income in the Satellite  Services
segment and a larger  operating loss in the Network Services  segment.  The
decrease in the  Satellite  Services  segment was primarily the result of a
lower  investment  base in  COMSAT  World  Systems  (CWS)  upon  which  the
regulated rate of return is calculated and increased  depreciation from new
satellites in COMSAT Mobile Communications (CMC). The increased loss in the
Network  Services  segment resulted from the positive impact in 1996 from a
licensing agreement that resolved patent-infringement disputes with certain
manufacturers of television  encryption and decryption  equipment at COMSAT
Laboratories  which did not reoccur in 1997.  Also affecting 1997 operating
income  were  expenses  of $4  million  for a  proxy  contest  and  related
litigation  brought to enforce  certain  provisions  of the  Communications
Satellite  Act of 1962,  which were settled in the second  quarter of 1997.
Operating income in 1996 was $107 million, $13 million below 1995.

     Other income  (expense)  for 1997 was a net expense of $3 million,  $4
million lower than 1996. This was primarily attributable to improvements in
the results of COMSAT International's (CI) equity investments. Other income
(expense) for 1996 was a net expense of $7 million,  $5 million higher than
1995.  This  was due to a full  year of  dividend  payments  in 1996 on the
Monthly Income Preferred  Securities (MIPS), which were issued in July 1995
(see Note 7 to the  financial  statements),  offset by a $3 million gain on
the sale of ICO Global Communications  (Holdings) Limited (ICO) shares. See
Note 5 to the financial statements.

     Interest  expense,  net of  amounts  capitalized  for  1997,  was  $42
million,  $7 million  higher than 1996.  The  increase  primarily  reflects
reduced  interest  capitalized  due to the completion of several  satellite
projects.  For 1996,  interest  expense net of amounts  capitalized was $35
million,  $4 million  below the previous  year.  This  improvement  was the
result of lower  interest  expense,  offset by a decrease  in the amount of
interest capitalized.

     In 1997, the corporation  sold its Clarksburg,  Maryland  property and
recognized a pre-tax gain of $7 million on the sale of the land. See Note 4
to the financial statements.

     The consolidated tax rate on income from continuing  operations before
taxes  and the  extraordinary  item  for  1997  has  improved  over  1996's
effective tax rate  principally  because of a reduction in state income tax
expense.

     Income from continuing  operations before  extraordinary item for 1997
was $29  million,  $7  million  below  last  year.  Income  for  1996  from
continuing operations before extraordinary item was $36 million, $7 million
below 1995.

     Basic  earnings  per share  for  continuing  operations  for 1997 were
$0.58,  $0.18 below 1996. For 1996, basic earnings per share were $0.76, as
compared  to $0.93  for 1995.  Diluted  earnings  per share for  continuing
operations  for 1997  were  $0.57,  a $0.17  decrease  from  1996.  Diluted
earnings per share for  continuing  operations for 1996 and 1995 were $0.74
and $0.91, respectively. See Note 10 to the financial statements.

     Extraordinary loss from early  extinguishment of debt, net of tax, for
1997 was $4 million ($0.08 per share).  This  represents the costs incurred
in 1997 from the  corporation's  repurchase  of $90  million  of its 8.125%
notes and $10  million  of its 7.7%  medium-term  notes.  See Note 6 to the
financial statements.

DISCONTINUED OPERATIONS

     The loss in 1997 from  discontinued  operations,  net of tax,  was $89
million ($1.78 per share,  fully diluted) compared to losses of $28 million
($0.56  per  share)  for 1996 and $6  million  ($0.12  per share) for 1995.
Discontinued   operations   include  the  operations  of  both  Ascent  and
substantially all of CRSI.

     COMSAT  began   accounting  for   substantially   all  of  CRSI  as  a
discontinued  operation on June 30, 1997.  During the fourth  quarter,  the
corporation  recognized an additional charge to discontinued  operations of
$30 million, after tax, related to the sale of CRSI. This additional charge
is primarily  attributable to losses now anticipated on the sale of CRSI as
well as  adjustments in the estimated  cost to complete  certain  long-term
contracts.  The total loss in discontinued operations for CRSI for 1997 was
$60  million,  after  tax.  See  Note 2 to  the  financial  statements  and
Management's Discussion and Analysis - Outlook.



                                     30

<PAGE>



     COMSAT began accounting for Ascent as a discontinued  operation on May
16, 1997,  when  COMSAT's  board of  directors  decided to  distribute  the
corporation's 80.67% interest in Ascent to COMSAT's  shareholders.  On June
27, 1997,  COMSAT completed the spinoff of Ascent as a tax-free dividend to
COMSAT's  shareholders.  The 1997 loss  from  discontinued  operations  for
Ascent was $29 million, net of tax. See Note 2 to the financial statements.

CONSOLIDATED RESULTS

     On a consolidated  basis,  including  discontinued  operations and the
extraordinary  item,  the net loss for 1997 was $64 million versus 1996 net
income of $9  million.  For  1995,  the  consolidated  net  income  was $38
million.

     Basic  losses  per share  for 1997 were  $1.32,  as  compared  to 1996
earnings per share of $0.18.  Basic earnings per share for 1995 were $0.81.
Diluted  losses  per share for 1997 were  $1.29,  as  compared  to  diluted
earnings per share for 1996 and 1995 of $0.18 and $0.79, respectively.  See
Note 10 to the financial statements.

SEGMENT OPERATING RESULTS

     The  corporation  has  reported  operating  results in two segments --
Satellite  Services  and  Network  Services  (see Note 15 to the  financial
statements).  The  Satellite  Services  segment  includes both COMSAT World
Systems (CWS) and COMSAT Mobile  Communications (CMC). The Network Services
segment  includes  COMSAT   International  (CI),  COMSAT  Laboratories  and
Government  Programs.  COMSAT  Laboratories and Government Programs results
now include  certain  non-manufacturing,  telecommunications  contracts and
businesses that were previously reported as part of CRSI.

SATELLITE SERVICES

     Satellite  Services  includes  the Federal  Communications  Commission
(FCC) regulated and  non-regulated  businesses of CWS and CMC. CWS provides
international   voice,   data,  video  and  audio   communications  as  the
statutorily  designated U.S.  participant in the global satellite system of
the International Telecommunications Satellite Organization (INTELSAT). CMC
provides maritime,  aeronautical and land mobile communications services as
the statutorily  designated U.S. participant in the global satellite system
of the International Mobile Satellite Organization (Inmarsat).

     Revenues in the Satellite  Services segment in 1997 were $431 million,
1% below last year.  Revenues in 1996 were $434  million,  $1 million below
1995.  Operating income in the Satellite  Services segment in 1997 was $124
million, a decline of $12 million as compared to 1996.  Operating income in
1996 was $137 million, $28 million below the previous year.

     CWS  revenues  for 1997 were $263  million,  4% below 1996.  Increased
revenues from Very Small Aperture  Terminal (VSAT) leases and International
Business  Service  (IBS)  traffic were offset by  contracted  reductions in
full-time voice revenues and lower fiber-optic cable restoration  revenues.
The lower voice revenues  stemmed  primarily from scheduled rate reductions
in  long-term  carrier  contracts  with AT&T,  MCI and Sprint,  CWS's three
largest  international  carrier  customers.  CWS's 1996  revenues were $273
million,  which  reflects a 7%  increase  over  1995.  The  improvement  in
revenues  came  primarily  from  increases in VSAT leases,  IBS traffic and
CWS's share of revenues  from the INTELSAT  system.  These  increases  were
partially  offset by reduced  revenues from  scheduled  rate  reductions in
long-term carrier contracts.

     Operating income for CWS in 1997 was $100 million, 4% below last year.
The 1997 results  reflect  increased  depreciation  from placing in service
three  INTELSAT  satellites  during the past 12  months,  offset in part by
improved earnings realized on carrier-to-carrier contracts and the recovery
of  certain  litigation  costs.  Operating  income  in 1996 in CWS was $105
million, a 5% decrease from the prior year. The decline in operating income
was the result of a lower  investment base upon which the regulated rate of
return is calculated.  This was the result of insurance  proceeds  received
from the February 1996 launch  failure of the INTELSAT 708  satellite.  See
Note 4 to the financial statements.

     Revenues in CMC for 1997 were $168 million, an increase of 4% compared
to the prior year.  The higher  revenues were primarily the result of sales
of Planet 1 terminals and service, and increases in CMC's share of revenues
from the  Inmarsat  system.  Offsetting  this  increase  in  revenues  were
decreases in analog  telephone  transmissions  and lower volume in the bulk
service contract with IDB Mobile  Communications (IDB). CMC's 1996 revenues
were  $161  million,  a  decrease  of 11% as  compared  to 1995.  The lower
revenues  were  primarily  the result of decreases in analog  telephone and
telex  revenues,  expiration of the American Mobile  Satellite  Corporation
(AMSC)  service  contract  in  December  1995 and lower  volume in the bulk
service contract with IDB.



                                     33

<PAGE>



     CMC's  operating  income for 1997 was $23  million,  $9 million  below
1996.  The decrease  was  primarily  the result of  increased  depreciation
associated  with two Inmarsat-3  satellites  placed in service during 1997,
and lower revenues and increased  costs related to Planet 1 service,  which
began  commercial  operation in 1997.  Operating income in CMC for 1996 was
$32  million,  or 42%  lower  than  1995 due to lower  revenues,  increased
depreciation  expense  associated with two Inmarsat-3  satellites placed in
service during 1996 and increased costs related to the start up of Planet 1
service.

NETWORK SERVICES

     Network  Services  includes CI,  COMSAT  Laboratories  and  Government
Programs. CI operates an integrated group of telecommunications  businesses
in countries with rapidly growing  telecommunications  markets and provides
individualized  digital  network  solutions to  customers  located in these
markets.  COMSAT Laboratories  consists of two main businesses -- technical
consulting and communications  products.  Government  Programs includes the
Commercial Satellite Communications  Initiative (CSCI) contract,  Satellite
Control Facility and Special Program Office.

     Network  Services  segment  revenues  in 1997 were $170  million,  $28
million, or 19% higher than 1996. Included in revenues and operating income
during 1996 was $8 million  related to a licensing  agreement that resolved
patent  infringement  disputes  with certain  manufacturers  of  television
encryption and decryption  equipment at COMSAT  Laboratories.  Revenues for
the Network Services  segment in 1996 were $143 million,  a 58% improvement
over  1995.  The  1997  Network  Services  segment  operating  loss was $16
million, compared to an operating loss of $5 million in the prior year. The
1996 loss was lower  primarily due to the positive  impact of the licensing
agreement  noted above.  The  operating  loss in 1996 was $13 million lower
than 1995.

     CI's  revenues  in 1997 and 1996  were $90  million  and $58  million,
respectively, 54% better than each of their comparative years. The increase
in revenues in CI was driven  primarily by  improvements in CI's operations
in Brazil,  Argentina and Venezuela.  Partially  offsetting the increase in
1996 as compared to 1995 was a decline in revenues in BelCom,  CI's company
operating in Russia and in the Newly Independent States (NIS).

     CI's  operating  loss in 1997 was $14 million,  $3 million  lower than
1996. The  improvement  was primarily the result of a decrease in losses at
BelCom.  Revenue  commitments under long-term  contracts  increased to $323
million at December  31,  1997,  as compared to $220  million at the end of
1996.  CI's  operating  loss in 1996 was $17  million,  16%  less  than the
previous  year's loss of $21 million.  This  improvement  was primarily the
result  of the  increase  in  revenues  in  Brazil  and a  decrease  in the
operating losses at BelCom.  Partially  offsetting these  improvements were
start-up costs associated with CI's newer companies in China,  Colombia and
Venezuela.

     In May 1997,  CI acquired  full  ownership of the Mexican  corporation
IntelCom Red S.A. de C.V.,  which was previously a wholly owned  subsidiary
of ICG Satellite Services,  Inc., and renamed it COMSAT Mexico S.A. de C.V.
(COMSAT Mexico). COMSAT Mexico offers business customers digital,  domestic
and  international  private-line  services to support voice, data and image
applications. In January 1997, CI sold its remaining interest in Philippine
Global  Communications,  Inc. (PhilCom) at book value for $34 million.  See
Notes 3 and 5 to the financial statements.

     COMSAT  Laboratories'  revenues for 1997 were $36 million, as compared
to $44 million for 1996. Exclusive of the $8 million of revenues related to
the 1996 agreement that resolved patent disputes, COMSAT Laboratories' 1997
revenues were at  approximately  the same level as 1996,  and 1996 revenues
were 39% higher than 1995.

     The operating  loss for COMSAT  Laboratories  for 1997 was $2 million,
compared  to  operating  income of $7 million  for 1996.  Exclusive  of the
income related to the agreement on patent disputes, the 1997 operating loss
was $1 million more than 1996,  and the 1996  operating loss was $3 million
lower than 1995.  The  Laboratories'  backlog at December 31, 1997, was $28
million, 33% higher than at the end of 1996.

     Government Programs' revenues in 1997 were $44 million, an increase of
$3 million over the previous year.  The increased  revenues were related to
the CSCI  contract  and were  offset  by lower  revenues  from two  Marisat
satellites  that  ceased  operating  in 1996  after 20  years  of  service.
Revenues  in  Government  Programs  in 1996 were $41  million,  $14 million
higher than 1995.  This increase was  primarily  due to increased  revenues
associated  with the CSCI contract,  which started in the fourth quarter of
1995.

     The  operating  loss for  Government  Programs  in 1997 was  $400,000,
compared to operating income of $5 million for 1996. This was the result of
lower revenues from the loss of the Marisat  satellites and increased costs
associated  with the CSCI  contract.  Government  Programs  1996  operating
income was $2 million below 1995.

     In March 1997,  COMSAT's board of directors  approved a strategic plan
to refocus the corporation on international  satellite services and digital
networking  services and technology as discussed in the corporation's  1996
Annual  Report  on  Form  10-K.  As a  part  of  the  strategic  plan,  the
corporation  decided to divest its  ownership  interest  in Ascent and sell
substantially  all of the  assets and  operations  of CRSI as well as other
non-core  assets.  On  June  27,  1997,  the  corporation  distributed  its
ownership  interest  in  Ascent  to its  shareholders  through  a  tax-free
dividend.

                                     35

<PAGE>

     In March 1998, the  corporation  signed a stock purchase  agreement to
sell  substantially  all of CRSI for  $116.5  million.  The  sale  price is
subject to adjustment  based on  inter-company  loans and advances  between
COMSAT  and  CRSI  at the  time of the  closing.  Closing  for the  sale is
expected  to occur  on or  before  June 30,  1998,  and is  dependent  upon
completion  of certain  conditions  agreed to by the  parties,  third party
consents and regulatory  filings.  The financial  impact of the transaction
was included in the corporation's  1997 loss from discontinued  operations.
As part of the agreement,  the  corporation is retaining  Electromechanical
Systems, Inc. and Plexsys International Corporation,  pending evaluation of
available  alternatives.  COMSAT also will retain and  complete a long-term
construction  contract for a radio  telescope in Green Bank, West Virginia.
JEFA  Wireless  Systems,  a wholly owned  subsidiary,  was disposed of in a
separate transaction in February 1998.

     The corporation's 1998 operating income from continuing  operations is
expected  to be better  than  1997,  while the net income  from  continuing
operations  is  expected  to be at  approximately  the same  level as 1997.
Following is a discussion of COMSAT's two business segments.

SATELLITE SERVICES

     In the  first  quarter  of 1998,  continued  progress  was made in the
corporation's ongoing efforts to restructure INTELSAT and Inmarsat.

     The INTELSAT  Board of Governors  and an internal  working  group have
approved a restructuring  plan that involves  creation of a separate entity
(referred to as "INC") to which six  satellites  would be  transferred.  An
Assembly of Parties  (meeting of  governments)  is now  scheduled for March
1998 at which final  approval  for an overall  restructuring  plan is to be
considered.  Assuming  that schedule is  maintained,  INC would be formally
established  as a separate  business  entity in the second quarter of 1998,
and an initial public  offering for INC would be expected to occur sometime
during the first half of 1999. The  restructuring  plan to be considered by
the  Assembly of Parties  includes  recommendations  on several key issues,
including  INC's  ownership  structure  and  competitive   safeguards.   As
currently proposed,  INTELSAT's direct ownership in INC would be limited to
10%, and individual ownership levels would be limited to 17%. The proposal,
however,  would  grandfather  the  corporation's  direct  ownership  in INC
pending  completion of the initial  public  offering to the extent that the
corporation's   direct   ownership   would  exceed  the  limit   ultimately
established.

     At its March 1998  meeting,  the Inmarsat  Council  approved a plan to
transfer the  operating  assets of the current  Inmarsat  intergovernmental
organization  to a new company.  The Council will present its proposed plan
to the  Inmarsat  Assembly  of Parties for  consideration  at a meeting now
scheduled  for  April  1998.  Under  the  proposal,  the  target  date  for
completing  the transition to a private  company is January 1, 1999.  While
the new company initially would not be publicly traded, it is expected that
the company would proceed with an initial public  offering within 24 months
after its creation. As currently proposed,  individual ownership in the new
company would be capped at 15%,  although COMSAT's current 22% ownership in
Inmarsat would be grandfathered. Prior to the public offering, owners would
be able to trade shares, and strategic investors would be able to invest up
to $500 million in equity in the new company.



                                     36

<PAGE>

     Approval  of  the  restructuring   proposals  under  consideration  at
INTELSAT  and  Inmarsat  will  require a vote of  two-thirds  of the member
governments  that are present and voting (up to 142 in the case of INTELSAT
and 81 in the case of Inmarsat,  with each having one vote) at the Assembly
of Parties at which approval is sought. The Inmarsat restructure  timetable
is contingent on Inmarsat  member  governments  reaching broad consensus on
implementing  the proposed  amendments to the Inmarsat  Convention prior to
formal  ratification.  If such consensus is not achieved,  the ratification
process could take longer. The corporation,  as a minority  shareholder and
the  U.S.   signatory   to  both   organizations,   lacks  the  ability  to
independently  effect a restructuring  of either INTELSAT or Inmarsat.  The
success  and  timing of the  corporation's  privatization  efforts  will be
dependent upon the corporation's ability to achieve a consensus among other
signatories and participating member governments.

     In April 1997, the corporation  petitioned the FCC for  classification
as a  non-dominant  carrier and for  regulatory  forbearance.  The petition
requests  that  limits  on the  company's  rate of  return  and  structural
separation  requirements  be removed  and that CWS be allowed to change its
tariff rates and introduce new services over the INTELSAT  satellite system
on  one-day  notice.  The  petition  has been  opposed  by  certain  of the
corporation's  competitors and customers.  The corporation expects that the
FCC will act on the petition in 1998,  but cannot predict with accuracy the
outcome and timing of FCC regulatory  action nor whether the FCC may impose
conditions  on a grant  of the  corporation's  petition,  such as  allowing
customers  some form of direct  access to the INTELSAT  system,  abrogating
certain provisions of the corporation's  inter-carrier  agreements with its
largest  carrier  customers,  or  requiring  the  corporation  to waive its
privileges and immunities as a INTELSAT signatory.

     The U.S. House of  Representatives  Commerce  Committee has approved a
bill entitled the "Communications  Satellite  Competition and Privatization
Act  of  1997"  (H.R.   1872)  over  strong   bipartisan   opposition   for
consideration by the House of Representatives. To become law, the bill will
have to be approved by the full  House,  considered  and passed by the U.S.
Senate and signed by the  President.  While the  corporation  supports  the
bill's  stated  objective  of  privatizing   INTELSAT  and  Inmarsat  in  a
pro-competitive manner, COMSAT is strongly opposed to the bill as proposed,
since  it  would  have an  extremely  punitive  effect  on  COMSAT  and its
shareholders.  However,  the bill is in an early  stage of the  legislative
process,  and the corporation expects that the objectionable  provisions of
the bill will be addressed and resolved in the later stages of the process.

     As proposed,  H.R. 1872 could  restrict  COMSAT from offering  certain
existing  and future  services  via the  INTELSAT  and  Inmarsat  satellite
systems and might relieve major customers from existing  traffic  contracts
with the corporation. The bill could impair COMSAT's investment in INTELSAT
and Inmarsat  by, among other  actions,  possibly  requiring  the return of
orbital positions and spectrum needed in INTELSAT and Inmarsat  operations.
The bill also would  direct the FCC to permit  other  companies to directly
access the  INTELSAT  and  Inmarsat  satellite  systems  in the U.S.,  thus
discontinuing   COMSAT's   exclusive  provider  role,  subject  to  certain
safeguards that would insure fair compensation to COMSAT. On the plus side,
the  bill  would  no  longer  require  the  FCC  to  defer  action  on  the
corporation's petition for non-dominant carrier classification until direct
access is  granted.  The  bill,  however,  would  link the  removal  of the
existing  10%  ownership  limitation  on  COMSAT's  common  stock under the
Satellite Act to the point in time when direct access is granted.  The bill
also specifies criteria for the privatization and proposed restructuring of
INTELSAT  that,  if not agreed to by the other member  nations of INTELSAT,
might  restrict  INTELSAT's  proposed new commercial  affiliate,  INC, from

                                    37

<PAGE>


accessing the U.S. market.  In addition,  if the  privatization of INTELSAT
and Inmarsat is not completed by a mandatory  timetable in accordance  with
the criteria,  non-core  INTELSAT and Inmarsat services might be foreclosed
from U.S. markets.

     The corporation is, and will continue, opposing the bill, unless it is
modified in an acceptable,  pro-competitive manner that would not adversely
affect  the  corporation's  business  and the  value  of its  shareholders'
investments in the INTELSAT and Inmarsat satellite systems.

     Effective  January 1, 1998,  the  corporation  changed its  accounting
policy with respect to the cost of series  satellites  lost at launch or in
orbit.  Such costs will be expensed in the period in which the satellite is
lost at launch or  experiences  a total failure in orbit.  Previously,  the
costs of such failed series  satellites  were amortized over their original
useful lives.  Partial  in-orbit  failures will be evaluated for impairment
according to the provisions of Statement of Financial  Accounting Standards
No.  121,  "Accounting  for the  Impairment  of  Long-lived  Assets and for
Long-lived  Assets to be  Disposed  of."  Effective  January 1,  1998,  the
corporation  also changed its  accounting  policy with respect to satellite
performance  incentives paid to manufacturers to capitalize the net present
value  of such  payments  as a  component  of the  cost  of the  satellite.
Previously,  certain of these payments were expensed as paid. These changes
will not have a material effect on the corporation's financial statements.

     COMSAT World Systems (CWS)  continues to be well positioned with major
international    carriers   through   long-term   agreements   to   provide
cost-competitive services for bulk usage beyond the year 2000. In addition,
CWS expects  growth  from the  provision  of services in emerging  markets,
including international VSAT and Asynchronous Transfer Mode (ATM) services.
CWS is expected to face increasing competition over the longer term.

     In addition  to seven  satellites  currently  on order,  INTELSAT  has
signed  a  lease  for  capacity  aboard  the  INSAT-2E   satellite  in  the
Asia-Pacific  region,  planned  for  launch  in the  second  half of  1998.
INTELSAT  launched  four VIII series  satellites  successfully  in 1997 and
plans for two  launches in 1998.  The new INTELSAT  VIII series  satellites
offer higher-power C-band capabilities to address various markets.

     COMSAT  Mobile  Communications  (CMC)  plans to continue to expand its
service  offerings and value-added  products to meet anticipated  growth in
customers'  needs. The increasing number of digital terminals with improved
operating  efficiency and reduced  service charges are expected to continue
to provide  traffic  growth in land mobile,  small  commercial and pleasure
boat,  and  business  traveler  markets.  CMC  expects to  continue to face
increasing  competition  from existing  Inmarsat service  providers,  other
wireless  communications  services  (including  C-band) and other potential
market entrants.

     In late 1996, the Federal Aviation  Administration  (FAA) selected CMC
to provide  satellite  and uplink  services for the Wide Area  Augmentation
System (WAAS). The initial contract is expected to generate revenues of $57
million  through 2001 and could generate  revenues of up to $100 million if
all options are exercised through 2006.

                                    38

     In late  1996 and early  1997,  the  corporation  reduced  its  direct
ownership in ICO and presently owns 1.7%. The corporation also continues to
hold an indirect  share of ICO through its ownership in Inmarsat,  which is
also an ICO  shareholder.  The  corporation  is  evaluating  its plans with
respect to  distribution  of ICO products and services and will continue to
assess whether its direct ownership is properly aligned with those plans.

     As with any new product, there are a number of factors that may affect
the  corporation's  ability  to  offer  Planet  1  and  ICO  services  on a
profitable basis. Such factors include the level of consumer acceptance and
demand,  the  quality  and  pricing  of  competitive   services,   and  the
performance of ground and space systems and customer terminals. In order to
offer  Planet 1 and ICO  services,  the  corporation  must  obtain  certain
regulatory  approvals.  See Notes 8 and 9 to the financial  statements.  In
addition,  ICO must receive the funding  required to complete its satellite
system.

NETWORK SERVICES

     COMSAT International (CI) will continue to operate an integrated group
of  telecommunications  companies that are engaged principally in providing
individualized  digital network  solutions to business clients and carriers
in selected  markets.  CI also plans to develop  prospective  international
telecommunications  opportunities  that are  consistent  with  its  digital
networking  strategy.  In this  regard,  CI will  continue to target  those
rapidly  growing  markets  where a  significant  number of CI's existing or
targeted clients are located (or in which they intend to locate).

     CI's  general  financial   performance  benchmark  is  for  individual
companies to be  operationally  cash-flow  positive  within three years and
profitable after five years of operation absent unforeseen circumstances or
problems.  As  part of its  integrated  approach  to  management  of  those
companies,  CI evaluates operating  performance,  strategic fit and overall
effectiveness  of  managerial  control to determine  whether to continue to
increase or reduce its investment in individual companies.  CI is currently
reviewing its investment in BelCom.

     In  early  1997,   the   Communications   Secretariat   of   Argentina
(Secretariat) issued resolutions which reserve for Nahuelsat,  the domestic
Argentine  satellite  operator,  certain  exclusive  rights for the sale of
domestic  Ku-band  satellite  services in Argentina.  COMSAT  Argentina has
reserved  sufficient  Ku-band  capacity  to address  its current and future
business  requirements  through  1998.  Following  1998,  however,   COMSAT
Argentina will be required to secure additional capacity from Nahuelsat for
new business. There can be no assurance that adequate Ku-band space segment
will be  available  at that  time,  or that  Nahuelsat  will have  adequate
back-up  capacity  in the event of a  satellite  failure,  or that if space
segment is available, it will be priced competitively.

     In September  1997, the  Secretariat  issued a resolution that permits
Telintar,  the exclusive provider of international voice telephony and data
services in  Argentina,  to provide  switched  domestic  Internet  services
within Argentina. The resolution is drafted broadly enough that it also may
be construed to permit Telintar to provide switched domestic data services.
Presently it is unclear,  however,  whether the Secretariat  will interpret
the  resolution  to apply  to  domestic  data  services.  COMSAT  Argentina
challenged the resolution on the ground that domestic switching of Internet
and/or data services by Telintar is not permitted  under its franchise.  In
November  1997,   COMSAT  Argentina   received  a  preliminary   injunction

                                    39

<PAGE>


suspending the  resolution.  The injunction will remain in effect until the
Secretariat rules on COMSAT Argentina's  request for administrative  relief
from the  resolution.  The  Secretariat has also appealed the imposition of
the  preliminary  injunction.  The  resolution,  together with other recent
actions of the Secretariat,  including its resolutions  awarding  Nahuelsat
the exclusive right to sell domestic Ku-band capacity in Argentina, appears
to indicate a willingness  of the  Secretariat  to adopt  initiatives  that
benefit large, domestic and incumbent  telecommunications service providers
to the  detriment  of  competitors,  such as  COMSAT  Argentina,  which are
smaller than the domestic  incumbents.  The corporation  intends to monitor
regulatory  developments in Argentina  closely.  There can be no assurance,
however,  that the recent actions of the  Secretariat  or other  regulatory
developments  in respect to those  actions  will be  resolved  without  any
material affect on COMSAT Argentina's future business prospects.

YEAR 2000 ISSUE

     The year 2000 issue is the result of computer  programs  being written
using two digits  rather  than four  digits to define the  applicable  year
(i.e. "97" for 1997).  Certain of the corporation's  computer programs that
have  date-sensitive  software may not operate  properly  when the last two
digits  become "00",  as will occur on January 1, 2000.  To the extent that
this situation may exist,  there is a potential for computer system failure
or miscalculations, which could cause disruption of operations. The problem
is not limited to computer programs, as some of the corporation's equipment
that has  date-sensitive  processors may not be able to process dates after
December 31, 1999.

     In the second  half of 1996,  the  corporation  initiated a program to
identify and properly address issues  associated with the year 2000 problem
in order to avoid interruption to the corporation's  operations at the turn
of the century.  The corporation has made substantial progress in assessing
how it will be impacted by the year 2000 issue. Currently,  the corporation
is in the process of  modifying  or  replacing  computer  systems and other
date-sensitive  equipment,  so that the  corporation's  key systems will be
year 2000 compliant.  The corporation  presently believes that such changes
to the corporation's key systems and equipment will be completed and tested
by the end of the second quarter of 1999.

     The  corporation's  current  estimate is that it will cost  between $3
million  and $5 million  prior to January 1, 2000,  to modify its  in-house
management  information systems,  customer products,  and other systems and
equipment  impacted by the year 2000 issue. The corporation does not expect
the costs directly  attributable  to the year 2000 issue to have a material
effect on its consolidated results from operations in a given year.

     Year 2000  modifications  and  replacements  are based on management's
best  estimates,  which were derived using  assumptions  of future  events,
including the continued  availability  of resources and the  reliability of
third party modification plans.  Specific factors that might cause material
differences  in  the  estimates  include,  but  are  not  limited  to,  the
availability and cost of personnel with appropriate  necessary skills,  the
ability  to locate and  correct  all  relevant  computer  code and  similar
uncertainties.

                  ANALYSIS OF CONSOLIDATED BALANCE SHEETS

ASSETS

     The corporation ended 1997 with $1.9 billion of assets, as compared to
$2.1 billion at December 31,  1996.  Included in current  assets in each of
their respective periods were $142 million and $378 million associated with
the net assets of discontinued operations.

     Current assets  decreased  during 1997 by $220 million,  of which $209
million was related to the spinoff of Ascent  which  occurred in June 1997.
See Note 2 to the financial statements.

     Property and  equipment  additions  amounted to $259 million for 1997.
The  increase  in  property  and  equipment  was  primarily  related to the
investment in new communication  property and equipment at CI and additions
related  to CWS's  and  CMC's  share of  INTELSAT  and  Inmarsat  satellite
programs.

     Investments  decreased $33 million during 1997 as the corporation sold
its  remaining  interest  in PhilCom  in January  1997 at book value of $34
million. See Notes 3 and 5 to the financial statements.

LIABILITIES

     The  corporation's  total  liabilities  increased  during  1997 by $53
million.  This was  primarily  the  result  of a $15  million  increase  in
borrowings  and an  increase  of $36  million  related  to the  Clarksburg,
Maryland  building  financing  transaction.  See  Note 4 to  the  financial
statements.

          ANALYSIS OF CASH FLOWS, LIQUIDITY AND CAPITAL RESOURCES

CASH FLOWS

     Cash from operating  activities  for 1997 was $169 million,  14% below
1996.  The  Satellite  Services  segment  generated  the  majority  of  the
corporation's cash from operations. The corporation made interest payments,
net of amounts capitalized, of $40 million and tax payments of $11 million.

     During  1997,   the   corporation   used  $221  million  in  investing
activities,  a 5% decrease  from 1996.  The 1997  purchases of property and
equipment  occurred in both the  Satellite  Services  and Network  Services
segments, as the corporation continued to make capital investments equal to
its related  shares of INTELSAT's  and  Inmarsat's  satellite  programs and
purchased  communications  plant and equipment  predominantly in CI's Latin
American companies.  The corporation expects to make additional investments
in property and equipment in 1998 at approximately the same level as 1997.

     Cash  proceeds  from  financing  activities  in  1997  were a net  $50
million,  as the  corporation  received  $34  million  as a  result  of the
Clarksburg financing  transaction.  See Note 4 to the financial statements.
Of the total  increase in short-term  borrowings,  $106 million was used to
repurchase  $100 million of  long-term  debt.  See Note 6 to the  financial
statements. The quarterly dividend throughout 1996 and the first quarter of
1997 was $0.195 per share and for the last three quarters of 1997 was $0.05
per share.

                                    41

<PAGE>


LIQUIDITY AND CAPITAL RESOURCES

     The  corporation's  working  capital at  December  31,  1997,  was $22
million,  $354 million  lower than at December  31,  1996.  The decrease in
working  capital  during 1997 was  primarily the result of the reduction in
current  assets of $209  million  due to the  spinoff of Ascent on June 27,
1997 (see Note 2 to the financial statements),  and the use of $106 million
of  commercial  paper  to  repurchase  long-term  debt  (see  Note 6 to the
financial  statements).  Cash  from  operating  activities  and  short-term
borrowings  will be used for the near term to fund  growth  and to  finance
working capital needs.

     The  corporation  has access to short-term and long-term  financing at
favorable rates. The  corporation's  current  long-term debt ratings are A-
from Standard and Poor's and A3 from  Moody's.  The  corporation's  current
commercial  paper  ratings  are A2 from  Standard  and  Poor's  and P2 from
Moody's.  The corporation's  $200 million commercial paper program had $150
million in  borrowings  outstanding  at December  31,  1997. A $200 million
credit agreement,  expiring in 1999, backs up the corporation's  commercial
paper program.  The  corporation  plans to reduce  short-term debt with the
proceeds from the sale of substantially all of the assets and operations of
CRSI. Consummation of the sale of CRSI, however, remains subject to certain
conditions. See Management's Discussion and Analysis - Outlook.

     During 1997, the corporation repurchased a total of $90 million of its
8.125% notes due 2004 using proceeds from short-term debt. This reduced the
total  outstanding  of the 8.125%  notes from $160  million at December 31,
1996,  to $70 million at December 31, 1997.  In addition,  the  corporation
repurchased $10 million of its 7.7%  medium-term  notes using proceeds from
short-term  debt.  This  reduced  the   corporation's   total   outstanding
medium-term  notes from $74 million at December 31, 1996, to $64 million at
December 31, 1997. The corporation  had $36 million  remaining under a $100
million medium-term note program at December 31, 1997. The medium-term note
program  is part  of a $200  million  debt  securities  shelf  registration
program initiated in 1994.

     The corporation's capital structure and debt-financing  activities are
regulated   by  the  FCC.   The   corporation   is  required  to  submit  a
capitalization plan to the FCC for review annually. In August 1997, the FCC
approved the corporation's 1997 capitalization plan. Under the approved FCC
guidelines,  the  corporation  is  subject  to a limit of $200  million  in
short-term debt, a maximum  long-term,  debt-to-total-capital  ratio of 45%
and an interest  coverage  ratio of 2.3 to 1. The latter two guidelines are
measured at year end. The corporation was in compliance with the guidelines
at December 31,  1997,  with a  long-term,  debt-to-total-capital  ratio of
44.1%, $163 million in short-term debt outstanding and an interest coverage
ratio of 2.6 to 1.

     If the  corporation  were to fail  to  satisfy  one or more of the FCC
guidelines as of an applicable  measurement  date, the corporation would be
required to seek advance FCC approval of future  financing  activities on a
case-by-case  basis.  If such  approval were not granted,  the  corporation
could be  required to reduce or  reschedule  planned  capital  investments,
reduce cash outlays, reduce debt or sell assets.

ITEM 8:     FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT AUDITORS


To the Shareholders of
COMSAT Corporation:

We have  audited the  accompanying  consolidated  balance  sheets of COMSAT
Corporation and its  subsidiaries as of December 31, 1997 and 1996, and the
related  consolidated  statements of income,  stockholders' equity and cash
flow for each of the three years in the period ended December 31, 1997. Our
audit also included the financial statement schedule listed in the index at
Item  14(a)2.  These  financial  statements  and  the  financial  statement
schedule  are  the  responsibility  of the  corporation'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 the 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   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 such consolidated  financial  statements  present fairly, in
all material  respects,  the financial  position of the corporation and its
subsidiaries  at  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.  Also, in our opinion, such financial statement schedule,  when
considered in relation to the basic consolidated financial statements taken
as a whole,  presents fairly in all material respects,  the information set
forth therein.

                    COMSAT CORPORATION AND SUBSIDIARIES
                      NOTES TO CONSOLIDATED FINANCIAL
                STATEMENTS For the Years Ended December 31,
                            1997, 1996 and 1995

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF  CONSOLIDATION.  Accounts of COMSAT  Corporation and its
     majority-owned  subsidiaries  (COMSAT  or the  corporation)  have been
     consolidated.   Significant   intercompany   transactions   have  been
     eliminated.  Ascent  Entertainment  Group,  Inc.  and  COMSAT  RSI are
     accounted for as discontinued operations (see Note 2).

     The  corporation  has  consolidated  its shares of the accounts of the
     International Telecommunications Satellite Organization (INTELSAT) and
     the  International  Mobile  Satellite  Organization  (Inmarsat).   The
     corporation's  ownership  interests in INTELSAT and Inmarsat are based
     primarily on the corporation's  usage of these systems. As of December
     31,  1997,  the  corporation  owned  18.0% of  INTELSAT  and  23.0% of
     Inmarsat.

     USE  OF  ESTIMATES.   The  preparation  of  financial   statements  in
     conformity  with generally  accepted  accounting  principles  requires
     estimates and  assumptions  that directly affect the amounts of assets
     and liabilities and disclosure of contingent assets and liabilities at
     the date of the  financial  statements  and the  reported  amounts  of
     revenues and expenses during the reporting period.  Actual results may
     differ from those  estimates.  Estimates are used in  determining  the
     loss on disposal of  discontinued  operations  and in  accounting  for
     long-term contracts, allowance for doubtful accounts, depreciation and
     amortization, employee benefit plans, taxes and contingencies.

     REVENUE  RECOGNITION.  Revenue from  satellite  services is recognized
     over the period  during which the  satellite  services  are  provided.
     Revenue  from  long-term  product,   system  integration  and  related
     services contracts is accounted for using the percentage-of-completion
     (cost-to-cost)  method.  Revenue  from other  services  is recorded as
     services are provided.

     INCOME TAXES AND  INVESTMENT  TAX CREDITS.  The  provision  for income
     taxes includes taxes currently  payable and those deferred  because of
     differences  between the  financial  statement and tax bases of assets
     and liabilities.  The corporation has earned investment tax credits on
     certain INTELSAT and Inmarsat  satellite costs. These tax credits have
     been  deferred  and are  being  recognized  as  reductions  to the tax
     provision over the estimated service lives of the related assets.

     EVALUATION  OF LONG-LIVED  ASSETS.  In  accordance  with  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," the  corporation  evaluates the potential  impairment of
     long-lived  assets,  including  goodwill,  based upon  projections  of
     undiscounted  cash flows whenever  events or changes in  circumstances
     indicate  that  the  carrying  amount  of an  asset  may not be  fully
     recoverable.  Management  believes  no  material  impairment  of these
     assets exists at December 31, 1997.

     MARKETABLE  SECURITIES.  The corporation's  marketable  securities are
     categorized as available for sale  securities,  as defined in SFAS No.
     115,   "Accounting   for  Certain   Investments  in  Debt  and  Equity
     Securities." Unrealized holding gains and losses are reflected, net of
     tax, as a separate  component of stockholders'  equity until realized.
     For the  purpose  of  computing  realized  gains and  losses,  cost is
     identified  on a specific  identification  basis.  Realized  gains and
     losses are  reported in "Other  income  (expense),  net" on the income
     statement.

     GOODWILL.  Goodwill  is  amortized  over 10 to 25  years.  Accumulated
     goodwill  amortization  was  $2,077,000 and $1,276,000 at December 31,
     1997 and 1996, respectively.

     OTHER ASSETS.  The cash surrender  values of life  insurance  policies
     (net of loans)  totaling  $86,597,000  and $71,724,000 at December 31,
     1997 and 1996,  respectively,  are included in "Other  assets." "Other
     income (expense),  net" on the income statement includes the increases
     in the cash surrender values of these policies.

     STOCK-BASED  COMPENSATION.  SFAS No. 123,  "Accounting for Stock-Based
     Compensation,"    requires   expanded   disclosures   of   stock-based
     compensation  arrangements with employees and encourages (but does not
     require)  compensation  cost to be measured based on fair value of the
     equity instrument awarded (see Note 10). The corporation has chosen to
     continue to account for employee  stock-based  compensation  using the
     intrinsic  value method  prescribed  in  Accounting  Principles  Board
     Opinion  No.  25,  "Accounting  for Stock  Issued to  Employees,"  and
     related  interpretations.  Accordingly,  compensation  costs for stock
     options are measured as the excess, if any, of the quoted market price
     of the corporation's stock at the date of the grant over the amount an
     employee must pay to acquire the stock.

     CASH  FLOW  INFORMATION.   The  corporation  considers  highly  liquid
     investments  with a  maturity  of three  months or less at the time of
     purchase to be cash equivalents.

     STATEMENT  PRESENTATION.   Certain  prior  period  amounts  have  been
     reclassified  to conform with the current  year's  presentation.  Most
     notably,  costs that are passed through to customers in the Government
     Programs  segment are now netted against the associated  revenues.  In
     addition,  the corporation's  share of Inmarsat  revenues,  net of the
     amount paid for using the Inmarsat  satellite  system, is presented in
     revenues. These reclassifications had no impact on previously reported
     results of operations or stockholders' equity.

     NEW ACCOUNTING PRONOUNCEMENTS.  In June 1997, the Financial Accounting
     Standards Board (FASB) issued SFAS No. 130,  "Reporting  Comprehensive
     Income,"  and  SFAS  No.  131,   "Disclosures  about  Segments  of  an
     Enterprise  and  Related   Information."   SFAS  No.  130  establishes
     standards for reporting  and display of  comprehensive  income and its
     components  (revenues,  expenses,  gains and  losses) in a full set of
     general-purpose  financial  statements.  SFAS No. 130 will require the
     corporation  to display  its  minimum  pension  liability  adjustment,
     foreign currency translation  adjustment and unrealized gain (loss) on
     available for sale securities as a component of  comprehensive  income
     rather than a component of changes in stockholders'  equity.  SFAS No.
     131  establishes  standards  for the way public  business  enterprises
     report   information   about   operating   segments  and  the  related
     disclosures

                                     49

<PAGE>



     about  products and services,  geographic  areas and major  customers.
     Adoption  of SFAS  No.  131 will not  have a  material  effect  on the
     corporation's   presentation   of   operating   segments  and  related
     disclosures.  Both  statements are effective for financial  statements
     issued for fiscal years beginning after December 15, 1997.

2.   DISCONTINUED OPERATIONS

     The corporation began accounting for Ascent  Entertainment Group, Inc.
     (Ascent), its entertainment  subsidiary,  and substantially all of the
     assets and operations of COMSAT RSI, Inc.  (CRSI),  its  manufacturing
     subsidiary,  as discontinued operations in the second quarter of 1997.
     The consolidated financial statements have been restated for all prior
     periods  presented to reflect the results of operations and net assets
     of Ascent and CRSI as discontinued operations.

     The income (loss) from discontinued operations, net of tax, for Ascent
     and CRSI for the three years ended  December 31, 1997,  is  summarized
     below:

     ASCENT ENTERTAINMENT GROUP, INC.
     --------------------------------

     The  corporation  distributed  its 80.67% interest in Ascent through a
     tax-free   dividend  to   shareholders   on  June  27,  1997.   COMSAT
     shareholders  of record on June 19, 1997 received 0.4888 of a share of
     Ascent  common  stock for each  share of COMSAT  common  stock  owned.
     Ascent was accounted for as a discontinued  operation beginning on May
     16,  1997,  the date on which  the  corporation's  Board of  Directors
     adopted a formal plan to effect the distribution.

     The loss  from the  discontinued  Ascent  operations,  net of tax,  is
     composed of :

     The  loss  on  disposal  includes  an  operating  loss  of  $5,020,000
     ($3,861,000 net of tax) for the period May 17, 1997,  through June 27,
     1997,  and costs of $4,075,000  incurred by COMSAT to  facilitate  the
     distribution.  The tax  expense  associated  with the loss on disposal
     includes   $4,421,000  to  recognize   additional  taxes  on  deferred
     intercompany gains while Ascent was included in COMSAT's  consolidated
     tax return.  The operating results are net of minority interest in net
     losses of consolidated subsidiaries.

     In December  1995,  Ascent  completed a public  offering of  5,750,000
     shares of its  common  stock.  COMSAT  retained  24,000,000  shares or
     80.67% of Ascent. Concurrent with the public offering, Ascent repaid a
     $140,000,000 intercompany note payable to COMSAT. Included in the 1995
     loss from  operations is a pre-tax gain of  $19,286,000 as a result of
     the public offering.

     The  tax-free  dividend  of  Ascent  common  stock was  recorded  as a
     reduction  of COMSAT's  consolidated  retained  earnings.  At June 27,
     1997, the book value of the net assets of Ascent totaled  $194,633,000
     and consisted of the following:

     COMSAT RSI, INC
     ---------------

     Substantially all of CRSI was accounted for as discontinued operations
     beginning on June 30,1997.  CRSI designs,  manufactures and integrates
     earth stations as well as wireless and advanced antenna systems.

     In February 1998, the corporation sold substantially all of the assets
     of JEFA Wireless  Systems  (JEFA),  a wholly owned  subsidiary of CRSI
     engaged in the wireless  communications  integration  and  intelligent
     transportation systems business in a separate transaction. Pursuant to
     the sale agreement,  the corporation  assigned to the buyer its rights
     in  certain  contracts  and made a  payment  of  $4,663,000,  net of a
     working capital adjustment at closing, to complete the transaction.


                                     51

<PAGE>



     On March 16,  1998,  the  corporation  entered  into a stock  purchase
     agreement  to  sell  substantially  all of  the  remainder  of  CRSI's
     businesses for cash of $116,500,000, subject to an adjustment based on
     intercompany  loans and advances  between the  corporation and CRSI at
     closing.  Closing  for the CRSI sale is expected to occur on or before
     June 30, 1998, and is dependent upon completion of certain  conditions
     agreed to by the parties, third party consents and regulatory filings.

     As   part   of   the   agreement,   the   corporation   is   retaining
     Electromechanical Systems, Inc. and Plexsys International Corporation,
     pending evaluation of available alternatives.  COMSAT will also retain
     and complete a long-term  construction  contract for a radio telescope
     in Green Bank, West Virginia.

     Discontinued  operations  include  management's  best estimates of the
     amounts  expected to be realized on the sale of net assets,  operating
     losses through anticipated disposal dates,  facility closure costs and
     the estimated costs to complete the long-term contract retained by the
     corporation.  These  estimates  could change as  additional  costs are
     incurred to complete the disposal and the long-term contract.

     The income (loss) from the discontinued  CRSI operations,  net of tax,
     is composed of:

     The  estimated  loss on disposal  includes a provision of  $50,296,000
     ($39,603,000  net of tax) to  writedown  CRSI's and  JEFA's  assets to
     their net  realizable  value.  The  estimated  loss on  disposal  also
     includes the estimated loss from CRSI and JEFA operations  through the
     anticipated  disposal dates of $29,837,000  ($20,604,000  net of tax).
     The estimated loss from operations of CRSI and JEFA includes operating
     losses,  facility closure costs and the estimated cost to complete the
     long-term  contract to be retained and  completed  by the  corporation
     pursuant to the sale terms.  Certain of the losses are not deductible,
     causing the  effective tax benefit to be lower than the benefit at the
     federal statutory rate of 35%.

</TABLE>

     Depreciation  is calculated  using the  straight-line  method over the
     estimated  service life of each asset.  The service lives for property
     and equipment are: satellites, 10 to 13 years; furniture, fixtures and
     equipment, 3 to 15 years; buildings and improvements, 3 to 40 years.

     Satellites   include   construction   costs,   launch  costs,   direct
     development costs, insurance costs and capitalized interest.  Costs of
     series  satellites  that are lost at  launch or that fail in orbit are
     carried, net of any insurance proceeds, in the property accounts.  The
     remaining net amounts are depreciated over the estimated  service life
     of a satellite of the same series.  At December 31, 1997 and 1996,  no
     failed  series  satellites  were  included  in  property.   Non-series
     satellites  that are lost at launch or fail in orbit  are  charged  to
     operations.

     On February 14, 1996, the launch of the INTELSAT 708 satellite failed.
     The  corporation's  share of the satellite's  costs was fully insured.
     Insurance  proceeds  totaling  $54,443,000 were received in the second
     quarter of 1996.

     SALE OF LAND. In September 1997, COMSAT sold its Clarksburg,  Maryland
     office  building  and  the  surrounding  land  for  $45,750,000  in an
     all-cash transaction. A gain of $7,261,000 ($4,211,000 net of tax) was
     recognized on the sale of land.  The  corporation  also entered into a
     10-year lease  agreement with the new owner to continue  occupying the
     office  building,  that  principally  houses COMSAT  Laboratories.  In
     addition to lease payments,  the corporation is responsible for taxes,
     insurance and maintenance of the building.  The  sale-leaseback of the
     office  building has been accounted for as a financing due to COMSAT's
     continuing involvement as the lessor of floor space in the building to
     non-COMSAT  tenants.  As a result, the historical cost of the building
     remains in property  and will be  depreciated  over the 10-year  lease
     term.

                                     54

<PAGE>



     A financing  obligation  of  $36,219,000,  representing  the  proceeds
     received  for the  building,  was  recorded at the time of sale.  This
     obligation  is being  amortized  at an  interest  rate of 8.50% as the
     lease  payments are made.  The net present value at December 31, 1997,
     totals $35,645,000,  of which $2,042,000 is reflected in other current
     liabilities and the remainder in other long-term liabilities.

     At  December  31,  1997,  the future  lease  payments  pursuant to the
     sale-leaseback are $4,994,000 in 1998,  $5,131,000 in 1999, $5,273,000
     in 2000,  $5,418,000  in  2001,  $5,567,000  in 2002  and  $28,488,000
     thereafter.   Rental   income   expected   to  be   received   through
     non-cancellable  sub-leases is  $1,254,000 in 1998,  $869,000 in 1999,
     $236,000  in  2000,  $81,000  in  2001,  $3,000  in 2002  and  $74,000
     thereafter.

5.   INVESTMENTS

     ICO.  At  December  31,  1997  and  1996,  the  corporation's   direct
     investment  in ICO  Global  Communications  (Holdings)  Limited  (ICO)
     amounted   to   $35,985,000   and   $30,794,000,   respectively.   The
     accompanying balance sheet also includes the corporation's $35,800,000
     and $30,713,000  share of Inmarsat's  investment in ICO as of December
     31, 1997 and 1996, respectively (See Note 8).

     In December 1996, the corporation reduced its direct investment in ICO
     by  selling  777,701  of its  shares  to other  ICO  shareholders  for
     $29,941,000.  The corporation  recognized a gain of $2,722,000 that is
     included in "Other income (expense), net" on the income statement.

     PHILCOM.  In June  1994,  the  corporation  acquired  an  interest  of
     approximately   17%  in   PhilCom,   a   provider   of   international
     communications  services  in the  Philippines,  for  $42,141,000.  The
     corporation's  share of PhilCom's  income or losses was recorded using
     the "equity  method" of  accounting  through the third quarter of 1996
     and is  included  in  "Other  income  (expense),  net"  on the  income
     statement.  In the fourth  quarter  of 1996,  the  corporation  sold a
     portion of its interest in PhilCom at book value for  $3,517,000.  The
     remainder  of its  investment  in PhilCom was sold in January  1997 at
     book value (see Note 3).

     The  corporation  realized  a gain  of  $1,987,000  from  the  sale of
     marketable equity  securities during 1997. The corporation  recognized
     losses  of   $1,008,000   and   $1,105,000   during   1997  and  1996,
     respectively,  for a decline in value of a marketable  equity security
     that was  deemed  other  than  temporary.  The  gains and  losses  are
     recorded in "Other income (expense), net" on the income statement.

6.   DEBT

     The corporation's capital and debt-financing  activities are regulated
     by the Federal  Communications  Commission  (FCC).  The corporation is
     required  to submit a financial  plan to the FCC for review  annually.
     Under existing FCC  guidelines,  the corporation is subject to a limit
     of $200,000,000 in short-term borrowings,  a maximum long-term,  debt-
     to-total-capital  ratio  of 45% and an  interest  coverage  ratio,  as
     defined,  of 2.3 to 1. At December 31, 1997,  the  corporation  was in
     compliance with those guidelines.

     COMMERCIAL PAPER. The corporation  issues short-term  commercial paper
     as needed with repayment terms of 90 days or less under a $200,000,000
     program. The corporation had outstanding borrowings of $149,506,000 at
     December 31, 1997 and  $17,993,000  at December 31, 1996. The weighted
     average  interest  rate on these  borrowings  was  6.51%  and 7.25% at
     December 31, 1997 and 1996, respectively.

     CREDIT FACILITIES. The corporation has a $200,000,000 revolving credit
     agreement,  which  expires  in  December  1999,  as a  backup  to  the
     commercial  paper  program.  There have been no borrowings  under this
     agreement.

     LONG-TERM DEBT.  Long-term debt,  including the corporation's share of
     INTELSAT and Inmarsat debt, at each year end consists of:

</TABLE>

     The principal  amount of debt  (excluding the Inmarsat lease financing
     obligations) maturing over the next five years is $0 in 1998 and 1999,
     $26,932,000 in 2000, $75,000,000 in 2001 and $35,910,000 in 2002.


                                     56

<PAGE>



     EARLY  EXTINGUISHMENT  OF DEBT.  During  the  period  March 25,  1997,
     through April 9, 1997,  the  corporation  offered to purchase for cash
     its 8.125% notes due April 1, 2004, in a  fixed-spread  offering.  The
     corporation  repurchased  $89,525,000  of the  8.125%  notes  and also
     $10,000,000  of  its  7.7%  medium-term   notes  using  proceeds  from
     short-term  debt.  The early  extinguishment  of debt  resulted  in an
     extraordinary loss of $6,231,000 ($3,946,000 net of tax).

     INMARSAT    LEASE    FINANCING    OBLIGATIONS.    Inmarsat    borrowed
     (pound)140,400,000 sterling under a capital lease agreement to finance
     the construction of second-generation  Inmarsat  satellites.  Inmarsat
     also entered into another  capital  lease  arrangement  to finance the
     construction costs of its third-generation  satellites. As of December
     31,  1997,   (pound)131,800,000  sterling  of  the  (pound)197,000,000
     sterling   available   for  this  purpose  has  been   borrowed.   The
     corporation's   share  of  these  lease  obligations  is  included  in
     long-term debt.  Inmarsat has hedged its  obligations  through various
     foreign  exchange  transactions  to minimize the effect of fluctuating
     interest and exchange rates (see Note 14).

     The corporation's  share of the payments under these lease obligations
     for each of the next five years is $19,130,000 in 1998, $19,616,000 in
     1999,  $20,765,000 in 2000,  $21,450,000 in 2001,  $12,222,000 in 2002
     and $29,402,000  thereafter.  These payments include interest totaling
     $26,081,000 and a current maturity of $13,785,000.

7.   MONTHLY INCOME PREFERRED SECURITIES

     In  July  1995,   COMSAT  Capital  I,  L.P.  (COMSAT  Capital)  issued
     $200,000,000 of Monthly Income  Preferred  Securities  (MIPS).  COMSAT
     Capital  is a  limited  partnership  formed  for the sole  purpose  of
     issuing  the MIPS and loaning the  proceeds  to COMSAT,  the  managing
     general partner. The MIPS were issued at a par value of $25 per share,
     and  dividends  are payable  monthly at an annual rate of 8.125%.  The
     MIPS are callable by the issuer after July 2000 at par value.

     The  proceeds of the MIPS were  loaned to COMSAT  under the terms of a
     8.125%,  30-year  subordinated  debenture  agreement.  This  agreement
     allows  COMSAT to extend the  maturity of the  debentures  until 2044,
     provided that COMSAT satisfies  certain  financial  covenants.  COMSAT
     Capital  has been  consolidated  in the  financial  statements  of the
     corporation  since the third  quarter of 1995.  The loan  between  the
     partnership  and  COMSAT has been  eliminated  in  consolidation.  The
     $200,000,000  of  MIPS  is  shown  on the  corporation's  consolidated
     balance  sheet as "preferred  securities  issued by  subsidiary."  The
     dividends  on these  securities  are  recorded  as  minority  interest
     expense of  $16,250,000,  $16,250,000 and $7,358,000 in 1997, 1996 and
     1995, respectively,  and are included in "Other income (expense), net"
     on the income statement.

8.   COMMITMENTS AND CONTINGENCIES

     PROPERTY AND EQUIPMENT.  As of December 31, 1997, the  corporation had
     commitments to acquire property and equipment  totaling  $194,543,000.
     Of this  total,  $166,957,000  is payable  over the next three  years.
     These commitments are related  principally to the corporation's  share
     of INTELSAT and Inmarsat satellite acquisition programs.

     LEASES.  The  corporation  leases  its  headquarters  building  from a
     partnership in which the corporation owns a 50% interest.  The initial
     term of the lease expires in 2008. In addition to lease payments,  the
     corporation is responsible for taxes, insurance and maintenance of the
     building.  The  corporation  also has  leases  of other  property  and
     equipment.  Rental expense under  operating  leases was $10,242,000 in
     1997,  $5,179,000 in 1996 and  $5,096,000  in 1995.  The future rental
     payments under operating  leases are $17,677,000 in 1998,  $19,858,000
     in 1999, $21,874,000 in 2000, $13,607,000 in 2001, $13,645,000 in 2002
     and $55,317,000 thereafter.

     GOVERNMENT CONTRACTS. The corporation and its subsidiaries are subject
     to, and are currently a party to, audits and investigations by various
     agencies which oversee  contract  performance  in connection  with the
     corporation's  contracts with the U.S. Government.  If the corporation
     is  found  liable  for  wrongdoing  as a  result  of such an  audit or
     investigation,  the  corporation  could be fined or subjected to other
     punitive actions.

     ENVIRONMENTAL  ISSUES. The corporation  reviews, on a quarterly basis,
     its estimates of costs of compliance with  environmental  laws and the
     cleanup of various sites,  including sites which governmental agencies
     have  designated the corporation as a potentially  responsible  party.
     When it is probable  that  obligations  have been incurred and where a
     minimum cost or a  reasonable  estimate of the cost of  compliance  or
     remediation  can be  determined,  the  applicable  amount is  accrued.
     Because of the uncertainties  associated with environmental assessment
     and  remediation  activities,  future  expense to remediate  currently
     identified sites could be higher than the liability currently accrued.
     Based on currently available information, however, management does not
     believe that any costs incurred in excess of those  currently  accrued
     will have a materially  adverse  effect on the financial  condition of
     the corporation.

     INVESTMENT IN ICO. In 1994, the corporation and Inmarsat  committed to
     invest in ICO (see Note 5). ICO plans to build and operate  spacecraft
     and related  terrestrial  facilities  for the  provision  of worldwide
     mobile  communications via handheld devices.  As of December 31, 1997,
     the   corporation's   investment   totaled   $35,985,000,    and   the
     corporation's share of Inmarsat's  investment totaled $35,800,000.  As
     of December 31, 1997,  the  corporation  had fulfilled its direct and,
     through Inmarsat, its indirect investment commitments to ICO.



                                     58

<PAGE>



     The corporation has applied to the FCC for authority to participate as
     an investor and service provider in ICO. In acting on the application,
     which is being opposed by ICO's  competitors,  the FCC will  determine
     whether  the  corporation  satisfies  the  requisite  legal and policy
     criteria to  participate  in ICO. The  corporation  believes  that all
     necessary  operating  authorizations  with  respect  to  ICO  will  be
     obtained,  although the FCC may condition the use of ICO telephones in
     the U.S. on  reciprocal  access by ICO's U.S.  competitors  to foreign
     markets. In addition,  the provision of ICO service in the U.S. may be
     subject to the availability of adequate spectrum on an economic basis.

     In May 1996 TRW,  Inc.  (TRW) filed a lawsuit  against ICO in the U.S.
     District  Court  for  the  Central  District  of  California   seeking
     injunctive relief and unspecified  monetary damages.  The lawsuit,  as
     amended, alleged that the proposed ICO satellite system would infringe
     two  patents  held by TRW. In  December  1997,  TRW and ICO reached an
     agreement that settled this dispute.

9.   REGULATORY ENVIRONMENT AND LITIGATION

     REGULATORY  ENVIRONMENT.  Under the Communications Act of 1934 and the
     Communications  Satellite Act of 1962, as amended,  the corporation is
     subject  to  regulation  by the FCC  with  respect  to  communications
     facilities  and  services  provided  through the INTELSAT and Inmarsat
     systems and to the rates charged for those services. In addition,  the
     telecommunications companies which the corporation operates in various
     developing countries are subject to regulation by the local regulatory
     bodies in those countries. Because the regulatory environment in those
     countries is rapidly  evolving as the local  economies are developing,
     these companies face  increasing  business  uncertainties  which could
     have an adverse effect on their operations in those countries.

     Until 1985, the corporation was, with minor exceptions,  the sole U.S.
     provider of  international  fixed satellite  communications  services.
     Since then, the FCC has  authorized  several  international  satellite
     systems separate from INTELSAT.  These separate U.S. systems currently
     compete against the corporation for voice, video and data traffic.  In
     1993,  the FCC  substantially  eliminated  prior  restrictions  on the
     ability  of  separate  systems  to  offer  public  switched  telephony
     services,  thereby  increasing  competition to the  corporation in the
     voice market.  The remaining FCC  restrictions on competitive  systems
     expired on December 31, 1996.

     In April 1997, the corporation  petitioned the FCC for  classification
     as a non-dominant carrier and for regulatory forbearance. The petition
     requests  that  limits  on  the  corporation's   rate  of  return  and
     structural separation requirements be removed and that the corporation
     be allowed to change its tariff rates and  introduce new services over
     the INTELSAT satellite system on one-day notice. The petition has been
     opposed by certain of the corporation's competitors and customers. The
     corporation expects that the FCC will act on the petition in 1998, but
     cannot  predict with accuracy the outcome and timing of FCC regulatory
     action nor  whether  the FCC may impose  conditions  on a grant of the
     corporation's petition, such as allowing customers some form of direct
     access to the INTELSAT system,  abrogating  certain  provisions of the
     corporation's   inter-carrier  agreements  with  its  largest  carrier
     customers or requiring the  corporation  to waive its  privileges  and
     immunities as an INTELSAT signatory.

                                     59

<PAGE>

     In  May  1996,   the   corporation   received   authority  to  provide
     communication  services,  including  Planet 1 and  other  land  mobile
     services outside of North America, over the Inmarsat-3 satellites. The
     corporation has applied to the FCC for authorization to offer Planet 1
     and other mobile services in the U.S. Those  applications,  which have
     been opposed by certain of the corporation's competitors,  are pending
     before the FCC.

     LITIGATION.  The  corporation  and its  subsidiaries  are a  party  to
     various  lawsuits  and  arbitration  proceedings  and are  subject  to
     various  claims and inquiries,  which  generally are incidental to the
     ordinary  course of its  business.  The  outcome of legal  proceedings
     cannot be  predicted  with  certainty.  Based on  currently  available
     information,  however, management does not believe that the outcome of
     any matter which is pending or threatened,  either  individually or in
     the  aggregate,   will  have  a  materially   adverse  effect  on  the
     consolidated   financial   condition  of  the  corporation  but  could
     materially affect  consolidated  results of operations in a given year
     or quarter.

     The FCC has adopted a rule  requiring any common carrier that provides
     interstate  service in the U.S. to contribute  to a universal  service
     fund  based  on  the  carrier's  total  interstate  and  international
     revenues. In addition to its international  services,  the corporation
     provides a small amount of interstate services which the FCC has ruled
     makes the corporation  subject to the full contribution  requirements.
     The  corporation  has appealed  the FCC's ruling to the U.S.  Court of
     Appeals for the Fifth  Circuit and has also  petitioned  the FCC for a
     partial waiver of the  contribution  requirement.  If the  corporation
     were to lose both  proceedings,  the corporation  would be required to
     make contributions  estimated at between $4,000,000 and $5,000,000 per
     year, based on its 1997 interstate and international  revenues,  which
     is more than its annual interstate revenues.

10.  COMMON STOCK

     EARNINGS PER SHARE.  The  corporation  has  implemented  SFAS No. 128,
     "Earnings  Per Share," which is effective  for fiscal  periods  ending
     after December 15, 1997.  Accordingly,  the  corporation  has restated
     earnings (loss) per share amounts for all prior periods reported. SFAS
     No. 128 requires the  presentation  of basic  earnings per share (EPS)
     and  diluted  earnings  per share,  instead of the  primary  and fully
     diluted EPS that was required by Accounting Principles Board No. 15.

     STOCK INCENTIVE  PLANS. The corporation has stock incentive plans that
     provide for the issuance of stock  options,  restricted  stock awards,
     stock  appreciation  rights and  restricted  stock  units.  A total of
     6,441,000  shares of common  stock may be  granted  under the  current
     plans.  As of December 31, 1997,  133,000 shares of the  corporation's
     treasury stock and 6,308,000  unissued common shares were reserved for
     these plans.  As of December 31, 1997,  no stock  appreciation  rights
     were outstanding.

     Adjustments  were made to equitably  increase the number of shares and
     decrease the exercise  price for all  outstanding  stock  options as a
     result of the tax-free spinoff of Ascent. Vested stock options held by
     Ascent  employees  generally  expired  90 days  after  the date of the
     spinoff.  Unvested stock options held by Ascent employees  continue to
     vest as long as the  employee is employed by Ascent and then expire 90
     days after vesting.

     Adjustments  were also made to increase the number of restricted stock
     awards and restricted  stock units  outstanding  for the effect of the
     Ascent spinoff.

     STOCK OPTIONS.  Under the current plans,  the exercise price for stock
     options may not be less than the fair  market  value of the stock when
     granted.  Options  vest over  three  years and  expire  after 10 to 15
     years.  The exercise price of certain  options  granted prior to 1993,
     pursuant to an expired  plan,  is equal to 50% of the market  price on
     the grant date. The cost of these awards, which is the 50% discount to
     market  when  granted,  was  recorded  as  unearned   compensation  in
     stockholders' equity. This unearned compensation has been amortized to
     expense over the three-year vesting period.

     RESTRICTED  STOCK AWARDS.  Restricted stock awards are shares of stock
     that are subject to restrictions  on their sale or transfer.  In 1997,
     1996  and  1995,  152,470,   66,000  and  91,000   "performance-based"
     restricted  stock awards were granted,  respectively.  The 1997 amount
     includes  an  adjustment  of  outstanding  awards  due to  the  Ascent
     spinoff.  Grantees have record ownership of the underlying securities,
     however all such  securities are subject to forfeiture at the end of a
     two-year  performance period. In addition to the two-year  performance
     period,  the  awards  are  further  subject  to a  three-year  vesting
     schedule.  The  weighted  average  fair  value  at date of  grant  for
     restricted stock awards granted during 1997, 1996 and 1995 was $23.71,
     $18.00  and $19.69  per  share,  respectively,  which in each case was
     equal to the market value of the common stock at the date of grant.

     At the end of the two-year performance period with respect to the 1996
     and 1995 grants,  37,250 and 76,000 shares,  net of amounts forfeited,
     had met the performance  criteria.  The expected cost of all grants is
     amortized over the performance and vesting period. The expense for all
     outstanding  grants  was  $870,000  in  1997,  $1,296,000  in 1996 and
     $939,000 in 1995.

     RESTRICTED  STOCK UNITS.  Restricted stock units entitle the holder to
     receive a  combination  of stock and cash equal to the market price of
     common stock for each unit,  when vested.  These units vest over three
     years. During 1997, 1996 and 1995,  respectively,  54,360,  34,000 and
     71,000  restricted stock units were granted . The 1997 amount includes
     an  adjustment of  outstanding  units due to the Ascent  spinoff.  The
     weighted  average fair value for the units granted  during 1997,  1996
     and 1995 was $25.50, $18.99 and $19.67 per unit,  respectively,  which
     in each case was equal to the market  value of the common stock at the
     date of grant.  Partially vested  restricted  stock units  outstanding
     totaled  110,200 at December  31,  1997,  and 197,000 at December  31,
     1996.  The cost of these  awards  is  amortized  to  expense  over the
     three-year  vesting  period.  The  expense in 1997,  1996 and 1995 was
     $575,000, $924,000 and $679,000, respectively.

     EMPLOYEE  STOCK  PURCHASE  PLAN.  Employees  may  purchase  stock at a
     discount through the  corporation's  Employee Stock Purchase Plan. The
     purchase  price of the  shares is the lower of 85% of the fair  market
     value of the stock on the  offering  date,  or 85% of the fair  market
     value of the stock on the last  business day of each month  throughout
     the one-year  offering  period.  The purchase  price on the respective
     offering dates for 1997, 1996 and 1995, was $21.36 (adjusted to $17.22
     subsequent to Ascent spinoff), $16.04 and $16.74, respectively.

     There were 181,000  shares,  254,000  shares and 236,000 shares issued
     under  this plan at  weighted  average  prices of  $18.26,  $16.03 and
     $16.37  for  the  years  ended  December  31,  1997,  1996  and  1995,
     respectively.  As of December 31, 1997, a total of 1,578,000 shares of
     the  corporation's  unissued  common stock has been  reserved for this
     plan.

     The  weighted  average  fair  value  of the  purchase  rights  granted
     pursuant  to this  plan in 1997,  1996 and 1995 was  $5.95,  $4.07 and
     $4.56,  respectively.  The  fair  value  of each  purchase  right  was
     estimated using the  Black-Scholes  model as of January 1 of each year
     assuming each plan year consisted of 12,  one-month  options,  and the

     PRO  FORMA  DISCLOSURES.  Had  stock-based  compensation  cost for the
     corporation's  stock incentive plans been determined based on the fair
     value  at  the  grant  dates  for  awards  under  those   plans,   the
     corporation's  income from continuing  operations before extraordinary
     item  would  have  been  decreased  by   $2,544,000,   $1,928,000  and
     $1,451,000 in 1997, 1996 and 1995,  respectively.  Assuming  dilution,
     the earnings per share for income from  continuing  operations  before
     extraordinary  item would have decreased by $0.05,  $0.04 and $0.03 in
     1997, 1996 and 1995, respectively. The pro forma effect on income from
     continuing  operations  before  extraordinary  item for 1997, 1996 and
     1995 is not  representative  of the pro forma  effect  on income  from
     continuing  operations  before  extraordinary  item  in  future  years
     because  it does not take into  consideration  pro forma  compensation
     expense related to grants made prior to 1995.

11.  PENSION AND OTHER BENEFIT PLANS

     The corporation has a  non-contributory,  defined benefit pension plan
     for  qualifying  employees.  Pension  benefits  are  based on years of
     service and compensation prior to retirement.

     The components of net pension expense (benefit) for each year are:

     The plan's assets consist  primarily of common  stocks,  corporate and
     government bonds and short-term investments.  The corporation's policy
     is to fund the minimum actuarially computed  contributions required by
     law. The corporation  made a $1,065,000 cash  contribution to the plan
     in 1996. No contribution was required for 1997.

     SUPPLEMENTAL   EXECUTIVE  RETIREMENT  PLAN.  The  corporation  has  an
     unfunded  supplemental  pension plan for  executives.  The expense for
     this plan was $2,163,000, $2,817,000 and $2,505,000 for 1997, 1996 and
     1995, respectively.

     The  corporation  recorded a minimum plan  liability for the excess of
     the  accumulated  benefit  obligation over the accrued plan liability.
     This was reported as a reduction to stockholders' equity of $2,222,000
     as of December 31, 1997 and $3,180,000 as of December 31, 1996.  These
     amounts  are net of  deferred  income  taxes and an  intangible  asset
     recorded for the unrecognized transition obligation.

</TABLE>

     The Internal  Revenue Service (IRS) has completed  examinations of the
     Federal income tax returns of the corporation through 1989. The IRS is
     currently   in  the  process  of   completing   examinations   of  the
     corporation's  Federal  income tax returns for 1990 through 1994.  The
     corporation  has also amended its returns and filed claims for refunds
     for 1979 through 1987,  which the IRS has denied.  The  corporation is
     contesting  the  IRS's  denial.  In the  opinion  of the  corporation,
     adequate  provision  has been made for  income  taxes for all  periods
     through 1997.

13.  PROVISION FOR RESTRUCTURING

     In the third  quarter  of 1995,  the  corporation  recorded  a pre-tax
     charge of $3,902,000, net of discontinued operations, to strategically
     restructure  elements of the  business  units  included in  continuing
     operations.  About  110  employees  were  severed  as  part  of  these
     activities.  The provision included  $1,858,000 for employee severance
     costs in COMSAT World  Systems  (CWS),  COMSAT  Mobile  Communications
     (CMC) and COMSAT International (CI), and $2,044,000 to downsize one of
     its divisions at COMSAT Laboratories. The actions taken in CWS and CMC
     were  associated  with  the   consolidation   of  the  management  and
     administration  of these two  businesses  into one business unit. As a
     result,  various  administrative,  marketing and other  positions were
     eliminated.  All  of  the  restructuring  actions  were  substantially
     completed at the end of 1995.

14.  FINANCIAL INSTRUMENTS AND OFF-BALANCE-SHEET RISKS

     The  corporation  owns a 50% interest in a partnership  which owns the
     headquarters  building  leased by the  corporation  (see Note 8).  The
     corporation has guaranteed repayment of a portion of the partnership's
     mortgage on the building.  The balance of the guarantee was $1,745,000
     as of December 31, 1997.  The guarantee  will be reduced as the loan's
     principal  balance is repaid.  The corporation  was also  contingently
     liable  to  banks  for  $12,889,000  as  of  December  31,  1997,  for
     outstanding   letters  of  credit  securing   performance  of  certain
     contracts.  The  estimated  fair  value  of these  instruments  is not
     significant.

     Inmarsat  has entered  into  foreign  currency  contracts  designed to
     minimize  exposure to exchange rate  fluctuations  on fixed  operating
     expenses denominated primarily in British pounds sterling. At December
     31, 1997, Inmarsat had several contracts maturing primarily in 1998 to
     purchase   foreign   currency  for  a  total  of   $119,714,000.   The
     corporation's share of the estimated fair value of these contracts, as
     determined  by  a  bank,  is  an  unrealized  gain  of   approximately
     $1,319,000 at December 31, 1997.

     Inmarsat  has entered into  interest  rate and foreign  currency  swap
     arrangements  to minimize  the  exposure to interest  rate and foreign
     currency  exchange  fluctuations  related to its  satellite  financing
     obligations.  Inmarsat  borrowed  and is  obligated  to  repay  pounds
     sterling.  The pounds sterling  borrowed were swapped for U.S. dollars
     with an agreement to exchange the dollars for pounds sterling in order
     to meet the future  lease  payments.  Inmarsat  pays  interest  on the
     dollars at an average  fixed rate of 8.8%,  and it  receives  variable
     interest on the sterling  amounts based on short-term LIBOR rates. The
     differential  to be paid or  received  is  accrued as  interest  rates
     change and is recognized over the life of the agreements. The currency
     swap  arrangements  have been  designated as hedges,  and any gains or
     losses are  included  in the  measurement  of the debt.  The effect of
     these  swaps  is  to  change  the  sterling  lease   obligation   into
     fixed-interest-rate dollar debt. As of December 31, 1997, Inmarsat had
     $367,060,000 of swaps to be exchanged for (pound)233,615,000  sterling
     at various dates  through 2007.  Inmarsat is exposed to loss if one or
     more of the  counter  parties  defaults.  However,  Inmarsat  does not
     anticipate  non-performance  by the  counter  parties as all are major
     financial institutions.  The corporation's share of the estimated fair
     value of these swaps is an unrealized loss of

                                     69

<PAGE>



     $8,427,000  at December  31,  1997.  The fair value was  estimated  by
     computing  the present value of the dollar  obligations  using current
     rates  available  for  issuance  of debt  with  similar  terms and the
     current value of the sterling at year-end exchange rates.

     The fair value of long-term debt (excluding  capitalized leases) shown
     below was estimated by obtaining a yield-adjusted price as of December
     31, 1997, for each obligation from an investment banker.

     The fair values of the remaining long-term debt not itemized above and
     the corporation's other financial  instruments are approximately equal

15.  BUSINESS SEGMENT INFORMATION

     The corporation  reports  operating  results and financial data in two
     business  segments:  Satellite  Services  and  Network  Services.  The
     Satellite  Services segment  consists of activities  undertaken by the
     corporation  in its  COMSAT  World  Systems  (CWS) and  COMSAT  Mobile
     Communications  (CMC) businesses.  CWS provides voice, data, video and

and the  Executive  shall  have  the  authority  to hire  and fire all such
employees within  established  budget  parameters,  PROVIDED that the Board

and write  independently,  if such activity does not conflict with the best
interests of COMSAT.  The Executive may keep all fees and other monies paid
for such outside board memberships and activities in accordance with COMSAT
corporate policy.

exclusive  property  of COMSAT  (as the  context  may  require).  Executive
acknowledges  that Trade Secrets have  economic  value to COMSAT due to the
fact that Trade Secrets are not generally  known to the public or the trade
and that the  unauthorized  use or disclosure of Trade Secrets is likely to
be detrimental to the interests of COMSAT and its  subsidiaries.  Executive
therefore  agrees to hold in strict  confidence  and not to disclose to any
third party any Trade Secret  acquired or created or developed by Executive
during  the  term of this  Agreement  except  (i)  when  Executive  uses or
discloses  any  Trade  Secret  in the  proper  course  of  the  Executive's
rendition  of services  to COMSAT  hereunder,  (ii) when such Trade  Secret
becomes public knowledge other than through a breach of this Agreement,  or
(iii) when  Executive is required to disclose any Trade Secret  pursuant to
any valid legal process.  The Executive shall notify COMSAT  immediately of
any such  legal  process in order to enable  COMSAT to  contest  such legal
process's  validity.  After  termination of this  Agreement,  the Executive
shall not use or otherwise  disclose Trade Secrets unless such  information
(x) becomes public knowledge other than through a breach of this Agreement,
(y) is  disclosed  to the  Executive  by a third  party who is  entitled to
receive and disclose such Trade Secret,  or (z) is required to be disclosed
pursuant  to any valid legal  process,  in which case the  Executive  shall
notify  COMSAT  immediately  of any such  legal  process in order to enable
COMSAT to contest such legal process's validity.

          (b) Upon the  effective  date of  notice  of the  Executive's  or
COMSAT's  election to  terminate  this  Agreement,  or at any time upon the
request of COMSAT, the Executive (or her heirs or personal representatives)
shall  deliver to COMSAT (i) all  documents  and  materials  containing  or
otherwise  relating  to Trade  Secrets  or other  information  relating  to
COMSAT's business and affairs, and (ii) all documents,  materials and other
property belonging to COMSAT, which in either case are in the possession or
under  the   control   of  the   Executive   (or  her  heirs  or   personal
representatives).  The  Executive  shall be entitled  to keep her  personal
records  (including  Rolodex)  relating  to COMSAT's  business  and affairs

                                    -6-

<PAGE>

except to the extent those  contain  documents  or  materials  described in
clause (i) of the preceding sentence.

     4.   DISCOVERIES  AND  WORKS.   All  discoveries  and  works  made  or
conceived by the Executive during her employment by COMSAT pursuant to this
Agreement,  jointly or with  others,  that  relate to  COMSAT's  activities
("Discoveries  and Works") shall be owned by COMSAT.  Discoveries and Works
shall include, without limitation, inventions, computer programs (including
documentation  of  such  programs),   technical  improvements,   processes,
drawings and works of authorship.  The Executive shall (a) promptly notify,
make full  disclosure  to, and execute and deliver any documents  requested
by, COMSAT to evidence or better assure title to such Discoveries and Works
in COMSAT,  (b) assist COMSAT in obtaining or maintaining for itself at its
own expense  United States and foreign  patents,  copyrights,  trade secret
protection or other  protection of any and all such  Discoveries and Works,
and (c)  promptly  execute,  whether  during  her  employment  by COMSAT or
thereafter, all applications or other endorsements necessary or appropriate
to maintain  patents and other rights for COMSAT and to protect their title
thereto.  Any  Discoveries  and Works  which,  within six months  after the
termination of the Executive's  employment by COMSAT, are made,  disclosed,
reduced to a tangible  or written  form or  description,  or are reduced to
practice  by the  Executive  and which  pertain  to work  performed  by the
Executive while with COMSAT shall, as between the Executive and COMSAT,  be
presumed to have been made during the Executive's employment b COMSAT.

     5.   TERMINATION.  This  Agreement  shall remain in effect  during the
Employment  Period,  and this  Agreement and  Executive's  employment  with
COMSAT may be terminated only as follows:

          (a) By the  Executive  at any  time  upon  forty-five  (45)  days
advance written notice to COMSAT for "Good Reason" (as defined  below).  In
such event or if the Executive's employment is terminated by COMSAT without
"cause" (as defined below),  the Executive shall be entitled to receive the
following  benefits  until the  earlier  of (i)  three  (3) years  from the
effective date of such termination,  or (ii) the later of (A) July 19, 2003
or (B) one year from such effective date: (i) her then current Base Salary;
(ii) an Annual  Bonus equal to seventy  percent  (70%) of her then  current
Base Salary;  and (iii) all other  benefits  provided  pursuant to Sections
2(c),  (d),  (e), (f) and (g) of this  Agreement,  which shall be deemed to
vest fully and immediately if subject to vesting.  The Executive shall have
no  obligation  to seek other  employment  in the event of her  termination
pursuant to this paragraph (a), and any such employment  shall not mitigate
COMSAT's obligations hereunder.

          "Good  Reason"  shall  mean  any  of  the   following:   (I)  any
substantial  reduction  (except in connection  with the  termination of her
employment voluntarily by the Executive or by COMSAT for "cause" as defined
below) by COMSAT,  without the Executive's  express written consent, of her

                                    -6-

<PAGE>

responsibilities  as President and Chief Executive Officer of COMSAT;  (II)
any change in the  reporting  structure  set forth in Section  1(b)  above;
(III) any  reduction  in  Executive's  title;  (IV) any  relocation  of the
Executive's  offices  outside the  Washington,  D.C.  metropolitan  area by
COMSAT without the  Executive's  express written consent prior to the third
anniversary  of  the  Effective  Date;  (V)  any  material  default  of the
provisions of Section 2 of this Agreement  which  continues for twenty (20)
business  days  following  COMSAT's  receipt  of  written  notice  from the
Executive  specifying  the  manner in which  COMSAT is in  default  of such
provisions;  (VI) the  Executive is not reelected to or is removed from the
Board;  or (VII) any officer  superior to the  Executive  is  appointed  by
COMSAT.

          (b) By COMSAT at any time  upon ten (10) days  written  notice to
the  Executive,  and after an opportunity to discuss such decision with the
Board,  for  "cause."  For  purposes of this  Agreement,  COMSAT shall have
"cause" to terminate  the  Executive's  employment  hereunder  upon (i) the
continued and  deliberate  failure of the Executive to perform her material
duties,  in a manner  substantially  consistent with the manner  reasonably
prescribed by the Board and in accordance  with the terms of this Agreement
(other than any such failure  resulting from her incapacity due to physical
or mental illness),  which failure  continues for twenty (20) business days
following  the  Executive's  receipt  of  written  notice  from  the  Board
specifying  the manner in which the  Executive is in default of her duties,
(ii) the engaging by the Executive in intentional  serious  misconduct that
is materially and demonstrably injurious to COMSAT or its reputation, which
misconduct, if it is reasonably capable of being cured, is not cured by the
Executive  within  twenty (20)  business  days  following  the  Executive's
receipt of written notice from the Board specifying the serious  misconduct
engaged in by the  Executive,  (iii) the  conviction  of the  Executive  of
commission of a felony involving a crime of moral turpitude, whether or not
such felony was committed in connection with COMSAT's business, or (iv) any
material breach by the Executive of Section 8 hereof,  which breach,  if it
is reasonably  capable of being cured, is not cured by the Executive within
twenty (20) business  days  following  the  Executive's  receipt of written
notice from the Board  specifying the breach of Section 8 by the Executive.
If COMSAT shall terminate the Executive's  employment for "cause,"  COMSAT,
in full  satisfaction of all of COMSAT's  obligations  under this Agreement
and in  respect  of the  termination  of the  Executive's  employment  with
COMSAT, shall pay the Executive her Base Salary and all other compensation,
benefits  and  reimbursement   through  the  date  of  termination  of  her
employment.

                                    -7-

<PAGE>


          (c) If, prior to the  expiration or termination of the Employment
Period,  the Executive shall have been unable to perform  substantially her
duties by reason of  disability  or  impairment  of health for at least six
consecutive calendar months,  COMSAT shall have the right to terminate this
Agreement by giving sixty (60) days written notice to the Executive to that
effect,  but only if at the time such  notice is given such  disability  or
impairment  is still  continuing.  Following  the  expiration of the notice
period,  the  Employment  Period  shall  terminate  with the payment of the
Executive's  Base  Salary  for the  month in which  notice  is given  and a
prorated  Annual Bonus through such month.  In the event of a dispute as to
whether the Executive is disabled within the meaning of this paragraph (a),
or the  duration  of any  disability,  either  party may  request a medical
examination of the Executive by a doctor appointed by the Chief of Staff of
a hospital  selected by mutual agreement of the parties,  or as the parties
may otherwise  agree,  and the written medical opinion of such doctor shall
be conclusive  and binding upon the parties as to whether the Executive has
become  disabled and the date when such disability  arose.  The cost of any
such medical  examinations shall be borne by COMSAT. In no event shall this
Agreement  terminate before COMSAT's  long-term  disability  benefits under
applicable plans become payable to the Executive.

          (d) If, prior to the  expiration or termination of the Employment
Period, the Executive shall die, COMSAT shall pay to the Executive's estate
her Base Salary and a prorated Annual Bonus through the end of the month in
which the Executive's  death occurred,  at which time the Employment Period
shall terminate without further notice.

          (e) If either  the  Executive  or COMSAT  elects not to renew the
Executive's employment with COMSAT at the end of the Employment Period, the
Executive shall be entitled to receive payments under the SERP beginning on
August 1, 2003,  the first day of the month  after the end of such  period,
calculated  in  accordance  with the  provisions  of the plan  based on the
Executive's  retirement on that date,  PROVIDED that the Board reserves the
discretion to waive the applicable  early  retirement  reduction  under the
plan in such event.  If the  Executive's  employment with COMSAT under this
Agreement  is  terminated  either by the  Executive  for Good  Reason or by
COMSAT without "cause," the Executive shall be entitled to receive payments
under the SERP  beginning on June 1, 2003, the first day of the month after
the Executive's 55th birthday, calculated in accordance with the provisions
of the plan as if the  Executive  retired on that date,  PROVIDED  that the
Board  reserves the  discretion to waive the  applicable  early  retirement
reduction under the plan in such event.

     6.   CHANGE OF CONTROL.

          (a) In the event that the Board in its sole discretion determines
that repeal of the ownership  restrictions  on COMSAT  capital stock in the

                                    -8-


Communications  Satellite Act of 1962 is reasonably  imminent,  the parties
shall  negotiate  in good  faith to adopt a "change of  control"  provision
applicable  to this  Agreement  which  shall set forth (i) the events  that
shall  constitute  a  "change  of  control"  for  this  purpose,  (ii)  the
consequences  under this Agreement if such a "change of control" occurs and
(iii) such other terms and  conditions as the parties shall  mutually agree
to.

          (b)  Any  "change  of  control"   provisions  adopted  by  COMSAT
applicable to any COMSAT  benefits plans which provide for the  accelerated
vesting  and/or  payment of any  benefits for its senior  executives  shall
apply to the Executive to the same extent as other COMSAT senior executives
on a most favored  nations  basis with respect to the benefits  affected by
such COMSAT provisions.

          (c) If a change of control (as  defined for  purposes of COMSAT's
benefit plans) occurs during the Employment  Period,  the change of control
shall  not  adversely  affect  any of the  Executive's  rights  under  this
Agreement,  and this Agreement  shall  continue in effect  according to its
terms. In the event of a change of control, the Executive shall be entitled
to vesting and payment of benefits according to the terms of this Agreement
or COMSAT's applicable plans, whichever is more favorable.

     7.   CERTAIN ADDITIONAL PAYMENTS.
          ---------------------------

          (a)  Notwithstanding  anything in this Agreement to the contrary,
in the event that it shall be determined that any payment or benefit to the
Executive,  whether pursuant to the terms of this Agreement or otherwise (a
"Payment"),  would  constitute  an "excess  parachute  payment"  within the
meaning of Section  280G of the Internal  Revenue Code of 1986,  as amended
(the "Code"), the Executive shall be paid an additional amount (a "Gross-Up
Payment")  such  that  the  net  amount  retained  by the  Executive  after
deduction of any excise tax imposed under Section 4999 of the Code, and any
federal,  state and local  income  and  employment  taxes and  excise  tax,
including any interest and penalties with respect thereto, imposed upon the
Gross-Up Payment shall be equal to the Payment. For purposes of determining
the amount of the Gross-Up  Payment,  the Executive  shall be deemed to pay
federal  income tax and  employment  taxes at the highest  marginal rate of
federal  income and  employment  taxation in the calendar year in which the
Gross-Up  Payment  is to be made and state and  local  income  taxes at the
highest  marginal  rate  of  taxation  in the  state  and  locality  of the
Executive's residence on the date the Payment is made, net of the reduction
in federal income taxes that the Executive may obtain from the deduction of
such state and local income taxes.

          (b) All  determinations  to be made under this Section 7 shall be
made by COMSAT's  independent  public  accountant  immediately prior to the
date the Payment is made (the "Accounting Firm"),  which firm shall provide
its determinations  and any supporting  calculations and workpapers both to

                                    -9-

<PAGE>


COMSAT  and  the  Executive   within  10  days  of  such  date.   Any  such
determination  by the Accounting  Firm shall be binding upon COMSAT and the
Executive.  Within  five  days  after  receipt  of  the  Accounting  Fir  s
determination,  COMSAT  shall pay to the  Executive  the  Gross-Up  Payment
determined by the Accounting Firm.

          (c) In the  event  that upon any  audit by the  Internal  Revenue
Service, or by a state or local taxing authority,  of a Payment or Gross-Up
Payment,  a change is finally  determined  to be  required in the amount of
taxes paid by the Executive,  appropriate  adjustments  shall be made under
this  Section  such that the net amount  which is payable to the  Executive
after  taking into account the  provisions  of Section 4999 of the Code and
any  interest  and  penalties  shall  reflect  the intent of the parties as
expressed  in  paragraph  (a)  above,  in  the  manner  determined  by  the
Accounting  Firm. The Executive shall notify COMSAT in writing of any claim
by the Internal  Revenue  Service  that, if  successful,  would require the
payment by COMSAT of a Gross-Up Payment.  Such notification  shall be given
as soon as  practicable  but no later  than ten  business  days  after  the
Executive is informed in writing of such claim and shall apprise  COMSAT of
the nature of such claim and the date on which such claim is  requested  to
be paid. The Executive  shall not pay such claim prior to the expiration of
the  30-day  period  following  the date on which it gives  such  notice to
COMSAT (or such shorter period ending on the date that any payment of taxes
with respect to such claim is due).  If COMSAT  notifies  the  Executive in
writing  prior to the  expiration of such period that it desires to contest
such claim, the Executive shall: (i) give COMSAT any information reasonably
requested  by COMSAT  relating  to such  claim;  (ii)  take such  action in
connection with contesting such claim as COMSAT shall reasonably request in
writing from time to time, including,  without limitation,  accepting legal
representation  with  respect  to  such  claim  by an  attorney  reasonably
selected  by COMSAT;  (iii)  cooperate  with  COMSAT in good faith in order
effectively to contest such claim; and (iv) permit COMSAT to participate in
any  proceedings  relating to such claim;  PROVIDED,  HOWEVER,  that COMSAT
shall bear and pay directly all costs and  expenses  (including  additional
interest and penalties)  incurred in connection with such contest and shall
indemnify and hold the Executive  harmless,  on an after-tax basis, for any
excise tax or income tax  (including  interest and  penalties  with respect
thereto)  imposed as a result of such  representation  and payment of costs
and  expenses.  Without  limitation  on the  foregoing  provisions  of this
Section 7, COMSAT shall control all  proceedings  taken in connection  with
such  contest  and,  at its sole  option,  may  pursue or forgo any and all
administrative  appeals,  proceedings,  hearings and  conferences  with the
taxing  authority in respect of such claim and may contest the claim in any
permissible manner, and the Executive agrees to prosecute such contest to a
determination  before any  administrative  tribunal,  in a court of initial
jurisdiction  and  in  one  or  more  appellate  courts,  as  COMSAT  shall

                                   -10-

<PAGE>

determine.  COMSAT's control of the contest shall be limited to issues with
respect to which a Gross-Up  Payment  would be  payable  hereunder  and the
Executive  shall be entitled to settle or contest,  as the case may be, any
other issue  raised by the  Internal  Revenue  Service or any other  taxing
authority.

          (d)  All of the  fees  and  expenses  of the  Accounting  Firm in
performing the  determinations  referred to in paragraphs (b) and (c) above
shall be borne  solely  by  COMSAT.  COMSAT  agrees to  indemnify  and hold
harmless the Accounting Firm from any and all claims,  damages and expenses
resulting from or relating to its determinations pursuant to paragraphs (b)
and (c) above,  except for claims,  damages or expenses  resulting from the
gross negligence or willful misconduct of the Accounting Firm.

     8.   NON-COMPETITION.

          (a) As an inducement for COMSAT to enter into this Agreement, the
Executive agrees that for a period  commencing as of the Effective Date and
running through the earlier of (i) the end of the Employment  Period if the
Executive  remains employed by COMSAT for the entire  Employment  Period or
(ii) one year following termination of the Executive's employment by COMSAT
for "cause" as defined in Section 5(b) hereof,  or by the Executive for any
reason  (other  than Good  Reason,  in which  case the  provisions  of this
paragraph  (a)  shall  not  apply)  (the  "Non-Competition   Period"),  the
Executive shall not, without the prior written consent of the Board, engage
or  participate,  directly or indirectly,  as principal,  agent,  employee,
employer,  consultant,  stockholder,  partner  or in any  other  individual
capacity  whatsoever,  in the conduct or management of, or own any stock or
any  other  equity  investment  in  or  debt  of,  any  business  which  is
competitive with any business conducted by COMSAT.

          For the purpose of this Agreement, a business shall be considered
to be  competitive  with any  business of COMSAT  only if such  business is
engaged in providing  services or products (i) comparable to or competitive
with (A) any service or product  currently  provided  by COMSAT  during the
Employment Period; (B) any service or product which evolves from or results
from enhancements in the ordinary course during the Non-Competition  Period
to the  services  or  products  provided by COMSAT as of the date hereof or
during  the  Employment  Period;  or (C) any  future  service or product of
COMSAT as to which the Executive materially and substantially  participated
in the development or enhancement,  and (ii) to customers,  distributors or
clients of the type served by COMSAT during the Non-Competition Period.

          (b)  NON-SOLICITATION  OF EMPLOYEES.  During the  Non-Competition
Period,  the Executive  will not (for her own benefit or for the benefit of
any person or entity  other than COMSAT)  solicit,  or assist any person or
entity other than COMSAT to solicit,  any officer,  director,  executive or

                                   -11-


employee (other than an administrative  or clerical  employee) of COMSAT to
leave his or her employment.

          (c) REASONABLENESS;  INTERPRETATION.  The Executive  acknowledges
and agrees,  solely for purposes of determining the  enforceability of this
Section 8 (and not for purposes of determining  the amount of money damages
or for any  other  reason),  that (i) the  markets  served  by  COMSAT  are
national and international and are not dependent on the geographic location
of executive  personnel or the businesses by which they are employed;  (ii)
the  length  of the  Non-Competition  Period  is  linked  to th term of the
Employment  Period and the severance  benefit provided for in Section 5(a);
and (iii) the above covenants are manifestly  reasonable on their face, and
the parties expressly agree that such restrictions have been designed to be
reasonable and no greater than is required for the protection of COMSAT. In
the event that the  covenants in this Section 8 shall be  determined by any
court of competent jurisdiction in any action to be unenforceable by reason
of  their  extending  for too  great a period  of time or over too  great a
geographical  area or by reason of their being too  extensive  in any other
respect,  they shall be  interpreted to extend only over the maximum period
of time  for  which  they  may be  enforceable,  and/or  over  the  maximum
geographical area as to which they may be enforceable and/or to the maximum
extent in all other  respects as to which they may be  enforceable,  all as
determined by such court in such action.

          (d)  INVESTMENT.  Nothing  in this  Agreement  shall be deemed to
prohibit  the  Executive  from  owning  equity or debt  investments  in any
corporation,  partnership or other entity which is competitive with COMSAT,
PROVIDED that such  investments (i) are passive  investments and constitute
five percent (5%) or less of the outstanding  equity  securities of such an
entity the equity  securities of which are traded on a national  securities
exchange or other public market, or (ii) are approved by the Board.

     9.   INDEMNIFICATION;  LIABILITY  INSURANCE.  The  Executive  shall be
entitled to indemnification and coverage under COMSAT's liability insurance
policy for directors and officers to the same extent as other directors and
officers of COMSAT. In addition,  the Executive shall be indemnified to the
maximum  extent  permitted  by law of the  jurisdiction  in which COMSAT is
incorporated, as it may be amended from time to time.


     10.  ENFORCEMENT.
          -----------

          (a) The Executive  acknowledges that a breach of the covenants or
provisions  contained in Sections 3, 4 and 8 of this  Agreement  will cause
irreparable  damage to COMSAT,  the exact amount of which will be difficult
to  ascertain,  and that the  remedies  at law for any such  breach will be
inadequate.  Accordingly,  the  Executive  agrees  that  if  the  Executive
breaches  or  threatens  to  breach  any of  the  covenants  or  provisions

                                   -12-

<PAGE>

contained  in  Sections  3, 4 and 8 of this  Agreement,  in addition to any
other remedy  which may be  available at law or in equity,  COMSAT shall be
entitled to seek specific  performance and injunctive  relief in a court of
competent jurisdiction after notice and a hearing.

          (b) The parties  expressly agree that any litigation  directly or
indirectly  arising  out of or  relating to this  Agreement,  including  an
action  brought by COMSAT  pursuant to  paragraph  (a) of this  Section 10,
shall be  brought  in a court of  competent  jurisdiction  in the  State of
Maryland.

     11.  SEVERABILITY.   Should  any   provision  of  this   Agreement  be
determined to be  unenforceable  or prohibited by any applicable  law, such
provision  shall be ineffective to the extent,  and only to the extent,  of
such  unenforceability or prohibition  without  invalidating the balance of
such  provision  or any other  provision  of this  Agreement,  and any such
unenforceability or prohibition in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     12.  ASSIGNMENT.  The Executive's  rights and  obligations  under this
Agreement  shall not be assignable by the  Executive.  COMSAT's  rights and
obligations  under this Agreement  shall not be assignable by COMSAT except
as  incident  to  the  transfer,   by  merger  or  otherwise,   of  all  or
substantially  all of the  business  of  COMSAT.  In the  event of any such
assignment  by COMSAT,  all rights of COMSAT  hereunder  shall inure to the
benefit of the  assignee,  PROVIDED  that all  references  herein to COMSAT
shall be deemed to refer with equal  force and effect to any  corporate  or
other successor of COMSAT.

     13.  NOTICES.  All notices and other communications which are required
or may be given  under  this  Agreement  shall be in  writing  and shall be
deemed to have been duly given when received if personally delivered;  when
transmitted if transmitted by telecopy,  electronic or digital transmission
method,  provided  that in such case it shall also be sent by  certified or
registered  mail,  return receipt  requested;  the day after it is sent, if
sent for next day  delivery to a domestic  address by  recognize  overnight
delivery  service (E.G.,  Federal  Express);  and upon receipt,  if sent by
certified or registered mail,  return receipt  requested.  Unless otherwise
changed by notice, in each case notice shall be sent to:

                 AMENDED AND RESTATED EMPLOYMENT AGREEMENT
                 -----------------------------------------


     This AMENDED AND RESTATED  AGREEMENT is made as of April 18, 1997, and
amended as of July 18, 1997, by and between COMSAT Corporation  ("COMSAT"),
a District of Columbia  corporation,  and Allen  Flower,  a resident of the
Commonwealth of Virginia (the "Executive").

     WHEREAS,  the Executive  serves as Vice President and Chief  Financial
Officer of COMSAT;

     WHEREAS, the Board of Directors of COMSAT (the "Board") believes it to
be in the best  interests of COMSAT to enter into this  Agreement to ensure
the Executive's continuing services to COMSAT; and

     WHEREAS,  COMSAT  desires to continue to employ the  Executive as Vice
President and Chief Financial Officer of COMSAT,  and the Executive desires
to continue such employment, on the terms and conditions set forth herein;

     NOW,  THEREFORE,  in  consideration  of the  premises  and the  mutual
agreements  made herein,  and intending to be legally bound hereby,  COMSAT
and the Executive agree as follows:

     1.   EMPLOYMENT; DUTIES.
          ------------------

          (a)  EMPLOYMENT AND  EMPLOYMENT  PERIOD.  COMSAT shall employ the

April 17, 2000 unless  terminated in accordance with the provisions of this
Agreement.  Each  12-month  period  ending on the  anniversary  date of the
Effective Date is referred to herein as a "year of the Employment Period."

     2.   COMPENSATION AND FRINGE BENEFITS.

          (a) BASE  COMPENSATION.  COMSAT  shall pay the  Executive  a base
salary ("Base Salary") during the Employment Period,  with payments made in
installments in accordance with COMSAT's  regular practice for compensating
executive personnel,  provided that in no event shall such payments be made
less frequently than twice per month.  The initial annual Base Salary shall
be  $210,000.  Thereafter,  the  Base  Salary  for the  Executive  shall be

          (b) BONUS COMPENSATION. The Executive will be eligible to receive
bonuses  ("Annual  Bonus")  during the  Employment  Period under the Annual
Incentive Plan (the "AIP") in accordance with the following parameters: (i)
the target bonus for each year during the Employment Period shall be 50% of
Base  Salary for  achieving  100% of the target  level for the  performance
measures  and (ii) the  performance  measures,  the  relative  weight to be
accorded  each  performance  measure  and the  amount of bonus  payable  in
relation to the target  bonus for  achieving  more or less than 100% of the
target level for the performance measures shall be determined for each year
during  the  Employment   Period  by  the  Committee  on  Compensation  and
Management Development of the Board (the "Compensation Committee").

          (c) FRINGE  BENEFITS.  The  Executive  shall be  entitled  to the
fringe  benefits in effect for COMSAT senior  executives from time to time,
including (i) participation in the COMSAT Directors and Executives Deferred

shall be entitled to such other or additional  fringe  benefits as are made
available to COMSAT senior executives during the Employment Period.  COMSAT
reserves the right to modify or  terminate at any time the fringe  benefits
provided to the senior management group.

          (d) SERP.  The Executive  shall  continue to  participate  in the
COMSAT  Insurance and  Retirement  Plan for  Executives  (the "SERP").  Any
future  amendments  or changes to the SERP which  provide for a  reduction,
deferral or elimination  of benefits  payable to  participants  in the SERP
shall  expressly not apply to the Executive  unless the Executive  consents
otherwise.

          (e)  LEGAL   EXPENSES.   The  Executive   shall  be  entitled  to
reimbursement  of the Executive's  reasonable legal fees and costs incurred
in connection with the negotiation and execution of this Agreement, subject

     3.   TRADE SECRETS; RETURN OF DOCUMENTS AND PROPERTY.
          -----------------------------------------------

          (a) The  Executive  acknowledges  that  during  the course of his
employment he will receive secret, confidential and proprietary information
("Trade  Secrets") of COMSAT and of other  companies with which COMSAT does
business on a  confidential  basis and that the  Executive  will create and
develop  Trade  Secrets  for the  benefit of COMSAT.  Trade  Secrets  shall
include,  without  limitation,  matters  of a  technical  nature,  such  as
scientific and engineering secrets,  "know-how," formulae, secret processes
or machines,  inventions and computer programs (including  documentation of
such programs), and matters of a business nature, such as customer data and
proprietary  information about costs, profits,  markets, sales and customer
databases,  and other  information  of a similar  nature to the  extent not
available  to the  public,  and plans  for  future  development.  All Trade
Secrets  disclosed to or created by the Executive shall be deemed to be the
exclusive property of COMSAT. The Executive acknowledges that Trade Secrets
have  economic  value to COMSAT due to the fact that Trade  Secrets are not
generally known to the public or the trade and that the unauthorized use or
disclosure of Trade Secrets is likely to be detrimental to the interests of
COMSAT and its  subsidiaries.  The  Executive  therefore  agrees to hold in
strict  confidence  and not to disclose to any third party any Trade Secret
acquired or created or developed by the  Executive  during the term of this
Agreement  except (i) when the Executive  uses o discloses any Trade Secret
in the proper  course of the  Executive's  rendition  of services to COMSAT
hereunder,  (ii) when such Trade Secret becomes public knowledge other than
through a breach of this Agreement, or (iii) when the Executive is required
to disclose  any Trade  Secret  pursuant to any valid  legal  process.  The
Executive  shall notify  COMSAT  immediately  of any such legal  process in
order to enable  COMSAT to contest  such legal  process's  validity.  After
termination  of this  Agreement,  the Executive  shall not use or otherwise
disclose Trade Secrets unless such information (x) becomes public knowledge
other than  through a breach of this  Agreement,  (y) is  disclosed  to the
Executive  by a third party who is entitled  to receive and  disclose  such
Trade  Secret,  or (z) is  required to be  disclosed  pursuant to any valid
legal process,  in which case the Executive shall notify COMSAT immediately
of any such legal  process in order to enable  COMSAT to contest such legal
process's validity.

          (b) Upon the  effective  date of  notice  of the  Executive's  or
COMSAT's  election to  terminate  this  Agreement,  or at any time upon the
request of COMSAT, the Executive (or his heirs or personal representatives)
shall  deliver to COMSAT (i) all  documents  and  materials  containing  or
otherwise  relating  to Trade  Secrets  or other  information  relating  to
COMSAT's business and affairs, and (ii) all documents,  materials and other
property belonging to COMSAT, which in either case are in the possession or
under  the   control   of  the   Executive   (or  his  heirs  or   personal
representatives).  The  Executive  shall be entitled  to keep his  personal
records  (including  Rolodex)  relating  to COMSAT's  business  and affairs
except to the extent those  contain  documents  or  materials  described in
clause (i) of the preceding sentence.

     4.  DISCOVERIES AND WORKS. All discoveries and works made or conceived
by  the  Executive  during  his  employment  by  COMSAT  pursuant  to  this
Agreement,  jointly or with  others,  that  relate to  COMSAT's  activities
("Discoveries  and Works") shall be owned by COMSAT.  Discoveries and Works

                                    -3-

<PAGE>

shall include, without limitation, inventions, computer programs (including
documentation  of  such  programs),   technical  improvements,   processes,
drawings and works of authorship.  The Executive shall (a) promptly notify,
make full  disclosure  to, and execute and deliver any documents  requested
by, COMSAT to evidence or better assure title to such Discoveries and Works
in COMSAT, (b) assist COMSAT in obtaining or maintain for itself at its own
expense  United  States  and  foreign  patents,  copyrights,  trade  secret
protection or other  protection of any and all such  Discoveries and Works,
and  promptly   execute,   whether  during  his  employment  by  COMSAT  or
thereafter, all applications or other endorsements necessary or appropriate
to maintain  patents  and other  rights for COMSAT and to protect its title
thereto.  Any  Discoveries  and Works  which,  within six months  after the
termination of the  Executive's  employment by COMSAT,  are made disclosed,
reduced to a tangible  or written  form or  description,  or are reduced to
practice  by the  Executive  and which  pertain  to work  performed  by the
Executive while with COMSAT shall, as between the Executive and COMSAT,  be
presumed to have been made during the Executive's employment by COMSAT.

     5.   TERMINATION.  This  Agreement  shall  remain in effect  during the
Employment  Period,  and this  Agreement and  Executive's  employment  with
COMSAT may be terminated only as follows:

          (a) The Executive's employment may be terminated by the Executive
at any time upon 45 days advance written notice to COMSAT for "Good Reason"
(as defined  below).  In such event,  or if the  Executive's  employment is
terminated  by COMSAT  without  "Cause" (as defined  below),  the Executive
shall be entitled to receive the following  benefits until the later of (x)
one year after the date of the Executive's termination of employment or (y)
April 17, 2000:

          (i)  The  Executive's  Base  Salary  in  effect  at the  date  of
  termination;

          (ii) An  Annual  Bonus  equal  to 50% of his  then  current  Base
  Salary; and

          (iii) All benefits  provided pursuant to Sections 2(c) and (d) of
this  Agreement,  which  shall be deemed to vest fully and  immediately  if
subject  to  vesting;  provided,  however,  that  in the  event  COMSAT  is
precluded from providing coverage under any such benefit plan by applicable
law or regulation, COMSAT may provide the Executive with a payment equal to
the cost of such  coverage  without  regard to tax  effect.  The  foregoing
benefits  shall be  calculated  in  accordance  with the  provisions of the
applicable   plans  as  if  the  Executive  had  retired  on  his  date  of
termination,  provided that the Board  reserves the discretion to waive the
applicable early retirement reduction under the SERP in such event.

          (b)  "Good  Reason"  shall  mean  the  occurrence  of  any of the
following (other than for "Cause"), without the Executive's express written
consent:  (i) the assignment to the Executive of duties  inconsistent  with
the Executive's  status as an executive  officer of COMSAT or a substantial
reduction  by COMSAT of the  Executive's  responsibilities  as an executive
officer of COMSAT;  (ii) any relocation of the Executive's  offices outside
the  Washington,  D.C.  metropolitan  area by  COMSAT  prior  to the  third

                                    -4-

<PAGE>


anniversary  of the Effective  Date;  or (iii) any material  default of the
provisions of Section 2 of this Agreement  which  continues for 20 business
days  following  COMSAT's  receipt of  written  notice  from the  Executive
specifying the manner in which COMSAT is in default of such provisions.  In
order for the  Executive to  terminate  employment  for "Good  Reason," the
Executive must give COMSAT written notice of his  termination of employment
for "Good Reason,"  stating the basis for the  termination,  within 90 days
after the  Executive  learns of the  occurrence  of the event  constituting
"Good Reason."

          (c) The  Executive's  employment  may be terminated by COMSAT for
Cause at any time upon ten days written notice to the Executive,  and after
giving the  Executive  an  opportunity  to discuss such  decision  with the
Board.  For  purposes  of this  Agreement,  COMSAT  shall  have  "Cause" to
terminate the Executive's  employment  hereunder upon (i) the continued and
deliberate  failure of the Executive to perform his material  duties,  in a
manner  substantially  consistent with the manner reasonably  prescribed by
the Board and in accordance  with the terms of this  Agreement  (other than
any such failure  resulting  from his  incapacity due to physical or mental
illness),  which  failure  continues  for 20 business  days  following  the
Executive's  receipt of written notice from the Board specifying the manner
in which the  Executive  is in default of his duties,  (ii) the engaging by
the Executive in  intentional  serious  misconduct  that is materially  and
demonstrably injurious to COMSAT or its reputation, which misconduct, if it
is reasonably  capable of being cured, is not cured by the Executive within
20 business days following the  Executive's  receipt of written notice from
the Board  specifying the serious  misconduct  engaged in by the Executive,
(iii) the conviction of the Executive of commission of a felony, whether or
not such felony was committed in connection with COMSAT's business, or (iv)
any material breach by the Executive of Section 10 hereof, which breach, if
it is  reasonably  capable  of being  cured,  i not cured by the  Executive
within 20 business days following the Executive's receipt of written notice
from the Board  specifying  the breach of Section 10 by the  Executive.  If
COMSAT shall terminate the Executive's  employment for "Cause," COMSAT,  in
full  satisfaction of all of COMSAT's  obligations under this Agreement and
in respect of the  termination of the  Executive's  employment with COMSAT,
shall  pay the  Executive  his  Base  Salary  and any  other  compensation,
benefits and  reimbursements due him under COMSAT plans through the date of
termination of his employment.

          (d) If, prior to the  expiration or termination of the Employment
Period,  the Executive shall have been unable to perform  substantially his
duties by reason of  disability  or  impairment  of health for at least six
consecutive calendar months,  COMSAT shall have the right to terminate this
Agreement by giving 60 days written notice to the Executive to that effect,
but only if at the time such notice is given such  disability or impairment
is still  continuing.  Following the expiration of the notice  period,  the
Employment  Period shall terminate with the payment of the Executive's Base
Salary for the month in which  notice is given and a prorated  Annual Bonus
through such month.  In the event of a dispute as to whether the  Executive
is disabled within the meaning of this Section 5(d), or the duration of any
disability, either party may request a medical examination of the Executive
by a doctor  appointed  by the  Chief of Staff of a  hospital  selected  by
mutual agreement of the parties, or as the parties may otherwise agree, and

                                    -5-

<PAGE>

the written  medical opinion of such doctor shall be conclusive and binding
upon the parties as to whether the  Executive  has become  disabled and the
date when such disability arose. The cost of any such medical  examinations
shall be borne by COMSAT. In no event shall this Agreement terminate before
COMSAT's  long-term  disability  benefits  under  applicable  plans  become
payable to the Executive.

          (e) If, prior to the  expiration or termination of the Employment
Period, the Executive shall die, COMSAT shall pay to the Executive's estate
his Base Salary and a prorated Annual Bonus through the end of the month in
which the Executive's  death occurred,  at which time the Employment Period
shall terminate without further notice.

          (f) If COMSAT elects not to renew the Executive's employment with
COMSAT at the end of the  Employment  Period and the  Executive  terminates
employment at the end of the  Employment  Period,  the  Executive  shall be
entitled to receive the  payments  described in Section  5(a)(i),  (ii) and
(iii) for the period  beginning on the date of the Executive's  termination
of  employment  and ending one year after the  Executive's  termination  of
employment.

          (g) If either  the  Executive  or COMSAT  elects not to renew the
Executive's employment with COMSAT at the end of the Employment Period, the
Executive shall be entitled to receive payments under the SERP beginning on
May 1, 2000 (the  first  day of the  month  after the end of such  period),
calculated  in  accordance  with the  provisions  of the SERP  based on the
Executive's  retirement on that date,  provided that the Board reserves the
discretion to waive the applicable  early  retirement  reduction  under the
SERP in such event.  If the  Executive's  employment with COMSAT under this
Agreement  is  terminated  either by the  Executive  for Good  Reason or by
COMSAT  without  Cause before the  Executive  attains age 55, the Executive
shall be entitled to receive  payments under the SERP beginning on December
1, 1998 (the first day of the month after the  Executive's  55th birthday),
calculated  in  accordance  with  the  provisions  of  the  SERP  as if the
Executive  retired  on that  date,  provided  that the Board  reserves  the
discretion to waive the applicable  early  retirement  reduction  under the
SERP in such event.  If the Executive dies before  payments begin under the
SERP, the  Executive's  surviving  spouse,  if any, shall receive under the
SERP a $200,000 lump sum death benefit,  plus annual benefit payments for a
ten year period equal to 50% of the  Executive's  accrued benefit under the
SERP,  according to the terms of the SERP.  The  provisions of this Section
5(g) shall be administered consistent with the terms of the SERP.

          (h) If  the  Executive  voluntarily  terminates  employment  with
COMSAT, such termination shall not be considered a breach of this Agreement
by the Executive and shall not adversely  affect the  Executive's  right to
receive such  benefits as may be payable to the Executive on account of his
termination  of employment  under  applicable  COMSAT plans.  The Executive
shall remain  obligated to comply with the  provisions of Sections 3, 4, 10
and 12 of this Agreement.

                                    -6-

<PAGE>

     6.   CHANGE OF CONTROL. If a change of control (as defined for purposes
purposes of COMSAT's  benefit plans) occurs during the Employment Term, the
change of control shall not adversely affect any of the Executive's  rights
under this Agreement, and this Agreement shall continue in effect according
to its terms.  In the event of a change of control,  the Executive shall be
entitled to vesting and payment of benefits  according to the terms of this
Agreement or COMSAT's applicable plans, whichever is more favorable.

     7.   CERTAIN ADDITIONAL PAYMENTS.

          (a)  Notwithstanding  anything in this Agreement to the contrary,
in the event that it shall be determined that any payment or benefit to the
Executive,  whether pursuant to the terms of this Agreement or otherwise (a
"Payment"),  would  constitute  an "excess  parachute  payment"  within the
meaning of Section  280G of the Internal  Revenue Code of 1986,  as amended
(the "Code"), the Executive shall be paid an additional amount (a "Gross-Up
Payment")  such  that  the  net  amount  retained  by the  Executive  after
deduction of any excise tax imposed under Section 4999 of the Code, and any
federal,  state and local  income  and  employment  taxes and  excise  tax,
including any interest and penalties with respect thereto, imposed upon the
Gross-Up Payment shall be equal to the Payment. For purposes of determining
the amount of the Gross-Up  Payment,  the Executive  shall be deemed to pay
federal  income tax and  employment  taxes at the highest  marginal rate of
federal  income and  employment  taxation in the calendar year in which the
Gross-Up  Payment  is to be made and state and  local  income  taxes at the
highest  marginal  rate  of  taxation  in the  state  and  locality  of the
Executive's residence on the date the Payment is made, net of the reduction
in federal income taxes that the Executive may obtain from the deduction of
such state and local income taxes.

          (b) All  determinations  to be made under this Section 7 shall be
made by COMSAT's  independent  public  accountant  immediately prior to the
date the Payment is made (the "Accounting Firm"),  which firm shall provide
its determinations  and any supporting  calculations and workpapers both to
COMSAT  and  the  Executive   within  10  days  of  such  date.   Any  such
determination  by the Accounting  Firm shall be binding upon COMSAT and the
Executive.  Within  five  days  after  receipt  of  the  Accounting  Firm's
determination,  COMSAT  shall pay to the  Executive  the  Gross-Up  Payment
determined by the Accounting Firm.

          (c) In the  event  that upon any  audit by the  Internal  Revenue
Service, or by a state or local taxing authority,  of a Payment or Gross-Up
Payment,  a change is finally  determined  to be  required in the amount of
taxes paid by the Executive,  appropriate  adjustments  shall be made under
this  Section  such that the net amount  which is payable to the  Executive
after  taking into account the  provisions  of Section 4999 of the Code and
any  interest  and  penalties  shall  reflect  the  intent of the partie as
expressed  in  paragraph  (a)  above,  in  the  manner  determined  by  the
Accounting  Firm. The Executive shall notify COMSAT in writing of any claim
by the Internal  Revenue  Service  that, if  successful,  would require the
payment by COMSAT of a Gross-Up Payment.  Such notification  shall be given
as soon as  practicable  but no later  than ten  business  days  after  the
Executive is informed in writing of such claim and shall apprise  COMSAT of

                                    -7-


the nature of such claim and the date on which such claim is requested to b
paid. The Executive shall not pay such claim prior to the expiration of the
30-day  period  following  the date on which it gives such notice to COMSAT
(or such shorter  period  ending on the date that any payment of taxes with
respect to such claim is due). If COMSAT  notifies the Executive in writing
prior to the  expiration  of such  period  that it desires to contest  such
claim,  the Executive  shall:  (i) give COMSAT any  information  reasonably
requested  by COMSAT  relating  to such  claim;  (ii)  take  such  action i
connection with contesting such claim as COMSAT shall reasonably request in
writing from time to time, including,  without limitation,  accepting legal
representation  with  respect  to  such  claim  by an  attorney  reasonably
selected  by COMSAT;  (iii)  cooperate  with  COMSAT in good faith in order
effectively to contest such claim; and (iv) permit COMSAT to participate in
any  proceedings  relating to such claim;  PROVIDED,  HOWEVER,  that COMSAT
shall bear and pay directly all costs and  expenses  (including  additional
interest and penalties)  incurred in connection with such contest and shall
indemnify and hold the Executive  harmless,  on an after-tax basis, for any
excise tax or income tax  (including  interest and  penalties  with respect
thereto)  imposed as a result of such  representation  and payment of costs
and  expenses.  Without  limitation  on the  foregoing  provisions  of this
Section 7, COMSAT shall control all  proceedings  taken in connection  with
such  contest  and,  at its sole  option,  may  pursue or forgo any and all
administrative  appeals,  proceedings,  hearings and  conferences  with the
taxing  authority in respect of such claim and may contest the claim in any
permissible manner, and the Executive agrees to prosecute such contest to a
determination  before any  administrative  tribunal,  in a court of initial
jurisdiction  and  in  one  or  more  appellate  courts,  as  COMSAT  shall
determine.  COMSAT's control of the contest shall be limited to issues with
respect to which a Gross-Up  Payment  would be  payable  hereunder  and the
Executive  shall be entitled to settle or contest,  as the case may be, any
other issue  raised by the  Internal  Revenue  Service or any other  taxing
authority.

          (d)  All of the  fees  and  expenses  of the  Accounting  Firm in
performing the  determinations  referred to in paragraphs (b) and (c) above
shall be borne  solely  by  COMSAT.  COMSAT  agrees to  indemnify  and hold
harmless the Accounting Firm from any and all claims,  damages and expenses
resulting from or relating to its determinations pursuant to paragraphs (b)
and (c) above,  except for claims,  damages or expenses  resulting from the
gross negligence or willful misconduct of the Accounting Firm.

     8.  SURVIVORSHIP. The respective rights and obligations of the parties
hereunder shall survive any  termination of the Executive's  employment and
the Employment Term to the extent necessary to the intended preservation of
such rights and obligations.
       

     9.  MITIGATION AND NO OFFSETS.  The Executive shall not be required to
mitigate  the  amount  of any  payment  or  benefit  provided  for in  this
Agreement by seeking  other  employment  or otherwise and there shall be no
offset against amounts due the Executive under this Agreement on account of
any  remuneration  attributable  to any subsequent  employment  that he may
obtain.  COMSAT's  obligations  to make payments  under this  Agreement and
otherwise to perform its obligations hereunder shall not be affected by any
circumstances,  including,  without limitation, any set-off,  counterclaim,

                                    -8-

<PAGE>


recoupment,  defense  or other  right  which  COMSAT may have  against  the
Executive or others.

     10.  NON-COMPETITION.

          (a)  NON-COMPETITION  AGREEMENT.  As an inducement  for COMSAT to
enter  into  this  Agreement,   the  Executive  agrees  that,   during  the
Non-Competition Period (as defined below), the Executive shall not, without
the prior written consent of the Board, engage or participate,  directly or
indirectly,   as  principal,   agent,   employee,   employer,   consultant,
stockholder, partner or in any other individual capacity whatsoever, in the
conduct or management  of, or own any stock or any other equity  investment
in or debt  of,  any  business  which  is  competitive  with  any  business
conducted by COMSAT. The Non-Competition Period is the period commencing as
of the  Effective  Date  and  running  through  the  date  that is one year
following  the  date  on  which  the  Executive's  employment  with  COMSAT
terminates for any reason.

          (b) COMPETITIVE  BUSINESS.  For the purpose of this Agreement,  a
business shall be considered to be competitive  with any business of COMSAT
only if such  business is engaged in  providing  services  or products  (i)
comparable  to or  competitive  with (A) any  service or product  currently
provided by COMSAT during the Employment Period; (B) any service or product
which  evolves from or results  from  enhancements  in the ordinary  course
during the  Non-Competition  Period to the services or products provided by
COMSAT as of the date hereof or during the  Employment  Period;  or (C) any
future  service or product of COMSAT as to which the  Executive  materially
and substantially participated in the development or enhancement,  and (ii)
to customers,  distributors  or clients of the type served by COMSAT during
the Non-Competition Period.

          (c)  NON-SOLICITATION  OF EMPLOYEES.  During the  Non-Competition
Period,  the Executive  will not (for his own benefit or for the benefit of
any person or entity  other than COMSAT)  solicit,  or assist any person or
entity other than COMSAT to solicit,  any officer,  director,  executive or
employee (other than an administrative  or clerical  employee) of COMSAT to
leave his or her employment.

          (d) REASONABLENESS;  INTERPRETATION.  The Executive  acknowledges
and agrees,  solely for purposes of determining the  enforceability of this
Section 10 (and not for purposes of determining the amount of money damages
or for any  other  reason),  that (i) the  markets  served  by  COMSAT  are
national and international and are not dependent on the geographic location
of executive  personnel or the businesses by which they are employed;  (ii)
the  length  of the  Non-Competition  Period  is  linked to the term of the
Employment Period; and (iii) the above covenants are manifestly  reasonable
on their face, and the parties  expressly agree that such restrictions have
been  designed to be  reasonable  and no greater  than is required  for the
protection  of COMSAT.  In the event that the  covenants in this Section 10
shall be determined by any court of competent jurisdiction in any action to

                                    -9-


be  unenforceable  by reason of their  extending  for too great a period of
time or over too great a geographical  area or by reason of their being too
extensive in any other  respect,  they shall be  interpreted to extend only
over the maximum period of time for which they may be  enforceable,  and/or
over the  maximum  geographical  area as to which  they may be  enforceable
and/or to the maximum  extent in all other respects as to which they may be
enforceable, all as determined by such court in such action.

          (e)  INVESTMENT.  Nothing  in this  Agreement  shall be deemed to
prohibit  the  Executive  from  owning  equity or debt  investments  in any
corporation,  partnership or other entity which is competitive with COMSAT,
provided that such  investments (i) are passive  investments and constitute
five percent or less of the outstanding equity securities of such an entity
the equity securities of which are traded on a national securities exchange
or other public market, or (ii) are approved by the Board.


     11.  INDEMNIFICATION;  LIABILITY  INSURANCE.  The  Executive  shall be
entitled to indemnification and coverage under COMSAT's liability insurance
policy for  officers  to the same extent as other  officers  of COMSAT.  In
addition,  the  Executive  shall  be  indemnified  to  the  maximum  extent
permitted by law of the jurisdiction in which COMSAT is incorporated, as it
may be amended from time to time.
          

     12.  ENFORCEMENT.
          -----------

          (a) The Executive  acknowledges that a breach of the covenants or
provisions  contained in Sections 3, 4 and 10 of this  Agreement will cause
irreparable  damage to COMSAT,  the exact amount of which will be difficult
to  ascertain,  and that the  remedies  at law for any such  breach will be
inadequate.  Accordingly,  the  Executive  agrees  that  if  the  Executive
breaches  or  threatens  to  breach  any of  the  covenants  or  provisions
contained  in  Sections 3, 4 and 10 of this  Agreement,  in addition to any
other remedy  which may be  available at law or in equity,  COMSAT shall be
entitled to seek specific  performance and injunctive  relief in a court of
competent jurisdiction after notice and a hearing.

          (b) The parties  expressly agree that any litigation  directly or
indirectly  arising  out of or  relating to this  Agreement,  including  an
action brought by COMSAT pursuant to this Section 12, shall be brought in a
court of competent jurisdiction in the State of Maryland.


     13.  EXPENSES OF ENFORCING THE AGREEMENT.  If the Executive  brings an
action to enforce any of the obligations of COMSAT under this Agreement and
prevails on any material  issue,  COMSAT shall pay the  Executive on demand
the amount  necessary to reimburse the Executive in full for all reasonable
expenses (including reasonable attorneys' fees and legal expenses) incurred
by the  Executive  in  enforcing  the  obligations  of  COMSAT  under  this
Agreement.


     14.  SEVERABILITY.   Should  any   provision  of  this   Agreement  be
determined to be  unenforceable  or prohibited by any applicable  law, such
provision  shall be ineffective to the extent,  and only to the extent,  of
such  unenforceability or prohibition  without  invalidating the balance of

                                   -10-

<PAGE>


such  provision  or any other  provision  of this  Agreement,  and any such
unenforceability or prohibition in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     15.  ASSIGNMENT.  The Executive's  rights and  obligations  under this
Agreement  shall not be assignable by the  Executive.  COMSAT's  rights and
obligations  under this Agreement  shall not be assignable by COMSAT except
as  incident  to  the  transfer,   by  merger  or  otherwise,   of  all  or
substantially  all of the  business  of  COMSAT.  In the  event of any such
assignment  by COMSAT,  all rights of COMSAT  hereunder  shall inure to the
benefit of the  assignee,  provided  that all  references  herein to COMSAT
shall be deemed to refer with equal  force and effect to any  corporate  or
other successor of COMSAT.

     16.  NOTICES.  All notices and other communications which are required
or may be given  under  this  Agreement  shall be in  writing  and shall be
deemed to have been duly given when received if personally delivered;  when
transmitted if transmitted by telecopy,  electronic or digital transmission
method,  provided  that in such case it shall also be sent by  certified or
registered  mail,  return receipt  requested;  the day after it is sent, if
sent for next day delivery to a domestic  address by  recognized  overnight
delivery  service (E.G.,  Federal  Express);  and upon receipt,  if sent by
certified or registered mail,  return receipt  requested.  Unless otherwise
changed by notice, in each case notice shall be sent to:

                 AMENDED AND RESTATED EMPLOYMENT AGREEMENT


     This AMENDED AND RESTATED  AGREEMENT is made as of April 18, 1997, and
amended as of July 18, 1997, by and between COMSAT Corporation  ("COMSAT"),
a District of Columbia corporation,  and Warren Y. Zeger, a resident of the
State of Maryland (the "Executive").

     WHEREAS,  the Executive serves as Vice President,  General Counsel and
Secretary of COMSAT;

     WHEREAS, the Board of Directors of COMSAT (the "Board") believes it to
be in the best  interests of COMSAT to enter into this  Agreement to ensure
the Executive's continuing services to COMSAT; and

     WHEREAS,  COMSAT  desires to continue to employ the  Executive as Vice
President,  General  Counsel and  Secretary  of COMSAT,  and the  Executive
desires to continue such employment,  on the terms and conditions set forth
herein;

     NOW,  THEREFORE,  in  consideration  of the  premises  and the  mutual
agreements  made herein,  and intending to be legally bound hereby,  COMSAT
and the Executive agree as follows:

     1.   EMPLOYMENT; DUTIES.

          (a)  EMPLOYMENT AND  EMPLOYMENT  PERIOD.  COMSAT shall employ the
Executive  to serve as Vice  President,  General  Counsel and  Secretary of
COMSAT or any  successor  entity  for a period  (the  "Employment  Period")
commencing  on  April  18,  1997  (the  "Effective  Date")  and  continuing
thereafter  until April 17, 2002 unless  terminated in accordance  with the
provisions  of  this   Agreement.   Each  12-month  period  ending  on  the
anniversary  date of the Effective Date is referred to herein as a "year of
the Employment Period."

          (b) OFFICES,  DUTIES AND  RESPONSIBILITIES.  The Executive  shall
report to the Chief Executive  Officer of COMSAT.  The Executive's  offices
initially  shall be located at COMSAT's  present  headquarters in Bethesda,
Maryland.  The Executive  shall have all duties and  authority  customarily
accorded a Vice President, General Counsel and Secretary.

          (c)  DEVOTION  TO  INTERESTS  OF COMSAT.  During  the  Employment
Period,  the Executive shall devote his best efforts and full business time
and attention to the performance of his duties  hereunder.  Notwithstanding
the  foregoing,  the  Executive  shall be  entitled  to  undertake  outside
activities (E.G. charitable,  educational, personal interests, and board of
directors memberships) that do not compete with COMSAT and do not




<PAGE>



unreasonably  or materially  interfere  with the  performance of his duties
hereunder  as  reasonably  determined  by the Chief  Executive  Officer  in
consultation with the Executive.

     2.   COMPENSATION AND FRINGE BENEFITS.
          --------------------------------

          (a) BASE  COMPENSATION.  COMSAT  shall pay the  Executive  a base
salary ("Base Salary") during the Employment Period,  with payments made in
installments in accordance with COMSAT's  regular practice for compensating
executive personnel,  provided that in no event shall such payments be made
less frequently than twice per month.  The initial annual Base Salary shall
be  $230,000.  Thereafter,  the  Base  Salary  for the  Executive  shall be
reviewed for increases  annually during the Employment  Period,  consistent
with COMSAT's  normal review  process.  Any Base Salary  increases shall be
approved by the Board in its sole discretion.

          (b) BONUS COMPENSATION. The Executive will be eligible to receive
bonuses  ("Annual  Bonus")  during the  Employment  Period under the Annual
Incentive Plan (the "AIP") in accordance with the following parameters: (i)
the target bonus for each year during the Employment Period shall be 50% of
Base  Salary for  achieving  100% of the target  level for the  performance
measures  and (ii) the  performance  measures,  the  relative  weight to be
accorded  each  performance  measure  and the  amount of bonus  payable  in
relation to the target  bonus for  achieving  more or less than 100% of the
target level for the performance measures shall be determined for each year
during  the  Employment   Period  by  the  Committee  on  Compensation  and
Management Development of the Board (the "Compensation Committee").

          (c) FRINGE  BENEFITS.  The  Executive  shall be  entitled  to the
fringe  benefits in effect for COMSAT senior  executives from time to time,
including (i) participation in the COMSAT Directors and Executives Deferred
Compensation  Plan,  the COMSAT Split  Dollar  Insurance  Plan,  the COMSAT
Educational  Grant Program,  the COMSAT Retirement Plan, the COMSAT Savings
and  Profit-Sharing  Plan,  the COMSAT 1995 Key  Employee  Stock Plan,  the
COMSAT  Employee  Stock  Purchase  Plan,  the COMSAT health and  disability
insurance  programs  and the COMSAT  financial  planning  program  and (ii)
reimbursement of reasonable expenses incurred in connection with travel and
entertainment  related to COMSAT's business and affairs. The Executive also
shall be entitled to such other or additional  fringe  benefits as are made
available to COMSAT senior executives during the Employment Period.  COMSAT
reserves the right to modify or  terminate at any time the fringe  benefits
provided to the senior management group.

          (d) SERP.  The Executive  shall  continue to  participate  in the
COMSAT  Insurance and  Retirement  Plan for  Executives  (the "SERP").  Any
future  amendments  or changes to the SERP which  provide for a  reduction,
deferral or elimination  of benefits  payable to  participants  in the SERP
shall  expressly not apply to the Executive  unless the Executive  consents
otherwise.

                                    -2-

<PAGE>


          (e)  LEGAL   EXPENSES.   The  Executive   shall  be  entitled  to
reimbursement  of the Executive's  reasonable legal fees and costs incurred
in connection with the negotiation and execution of this Agreement, subject
to a maximum reimbursement of $5,000.


     3.   TRADE SECRETS; RETURN OF DOCUMENTS AND PROPERTY.
          -----------------------------------------------

          (a) The  Executive  acknowledges  that  during  the course of his
employment he will receive secret, confidential and proprietary information
("Trade  Secrets") of COMSAT and of other  companies with which COMSAT does
business on a  confidential  basis and that the  Executive  will create and
develop  Trade  Secrets  for the  benefit of COMSAT.  Trade  Secrets  shall
include,  without  limitation,  matters  of a  technical  nature,  such  as
scientific and engineering secrets,  "know-how," formulae, secret processes
or machines,  inventions and computer programs (including  documentation of
such programs), and matters of a business nature, such as customer data and
proprietary  information about costs, profits,  markets, sales and customer
databases,  and other  information  of a similar  nature to the  extent not
available  to the  public,  and plans  for  future  development.  All Trade
Secrets  disclosed to or created by the Executive shall be deemed to be the
exclusive property of COMSAT. The Executive acknowledges that Trade Secrets
have  economic  value to COMSAT due to the fact that Trade  Secrets are not
generally known to the public or the trade and that the unauthorized use or
disclosure of Trade Secrets is likely to be detrimental to the interests of
COMSAT and its  subsidiaries.  The  Executive  therefore  agrees to hold in
strict  confidence  and not to disclose to any third party any Trade Secret
acquired or created or developed by the  Executive  during the term of this
Agreement  except (i) when the Executive  uses o discloses any Trade Secret
in the proper  course of the  Executive's  rendition  of services to COMSAT
hereunder,  (ii) when such Trade Secret becomes public knowledge other than
through a breach of this Agreement, or (iii) when the Executive is required
to disclose  any Trade  Secret  pursuant to any valid  legal  process.  The
Executive  shall notify  COMSAT  immediately  of any such legal  process in
order to enable  COMSAT to contest  such legal  process's  validity.  After
termination  of this  Agreement,  the Executive  shall not use or otherwise
disclose Trade Secrets unless such information (x) becomes public knowledge
other than  through a breach of this  Agreement,  (y) is  disclosed  to the
Executive  by a third party who is entitled  to receive and  disclose  such
Trade  Secret,  or (z) is  required to be  disclosed  pursuant to any valid
legal process,  in which case the Executive shall notify COMSAT immediately
of any such legal  process in order to enable  COMSAT to contest such legal
process's validity.

          (b) Upon the  effective  date of  notice  of the  Executive's  or
COMSAT's  election to  terminate  this  Agreement,  or at any time upon the
request of COMSAT, the Executive (or his heirs or personal representatives)
shall  deliver to COMSAT (i) all  documents  and  materials  containing  or
otherwise  relating  to Trade  Secrets  or other  information  relating  to
COMSAT's business and affairs, and (ii) all documents,  materials and other
property belonging to COMSAT, which in either case are in the possession or
under  the   control   of  the   Executive   (or  his  heirs  or   personal
representatives).  The  Executive  shall be entitled  to keep his  personal
records  (including  Rolodex)  relating  to COMSAT's  business  and affairs

                                    -3-


except to the extent those  contain  documents  or  materials  described in
clause (i) of the preceding sentence.

     4.   DISCOVERIES  AND  WORKS.   All  discoveries  and  works  made  or
conceived by the Executive during his employment by COMSAT pursuant to this
Agreement,  jointly or with  others,  that  relate to  COMSAT's  activities
("Discoveries  and Works") shall be owned by COMSAT.  Discoveries and Works
shall include, without limitation, inventions, computer programs (including
documentation  of  such  programs),   technical  improvements,   processes,
drawings and works of authorship.  The Executive shall (a) promptly notify,
make full  disclosure  to, and execute and deliver any documents  requested
by, COMSAT to evidence or better assure title to such Discoveries and Works
in COMSAT, (b) assist COMSAT in obtaining or maintain for itself at its own
expense  United  States  and  foreign  patents,  copyrights,  trade  secret
protection or other  protection of any and all such  Discoveries and Works,
and  promptly   execute,   whether  during  his  employment  by  COMSAT  or
thereafter, all applications or other endorsements necessary or appropriate
to maintain  patents  and other  rights for COMSAT and to protect its title
thereto.  Any  Discoveries  and Works  which,  within six months  after the
termination of the Executive's  employment by COMSAT, are made,  disclosed,
reduced to a tangible  or written  form or  description,  or are reduced to
practice  by the  Executive  and which  pertain  to work  performed  by the
Executive while with COMSAT shall, as between the Executive and COMSAT,  be
presumed to have been made during the Executive's employment by COMSAT.

     5.   TERMINATION.  This  Agreement  shall remain in effect  during the
Employment  Period,  and this  Agreement and  Executive's  employment  with
COMSAT may be terminated only as follows:
       

          (a) The Executive's employment may be terminated by the Executive
at any time upon 45 days advance written notice to COMSAT for "Good Reason"
(as defined  below).  In such event,  or if the  Executive's  employment is
terminated  by COMSAT  without  "Cause" (as defined  below),  the Executive
shall be entitled to receive the following benefits until April 17, 2002:

          (i)  The  Executive's  Base  Salary  in  effect  at the  date  of
termination;

          (ii) An  Annual  Bonus  equal  to 50% of his  then  current  Base
Salary; and

          (iii) All benefits  provided pursuant to Sections 2(c) and (d) of
this  Agreement,  which  shall be deemed to vest fully and  immediately  if
subject  to  vesting;  provided,  however,  that  in the  event  COMSAT  is
precluded from providing coverage under any such benefit plan by applicable
law or regulation, COMSAT may provide the Executive with a payment equal to
the cost of such  coverage  without  regard to tax  effect.  The  foregoing
benefits  shall be  calculated  in  accordance  with the  provisions of the
applicable   plans  as  if  the  Executive  had  retired  on  his  date  of

                                    -5-

<PAGE>


termination,  provided that the Board  reserves the discretion to waive the
applicable early retirement reduction under the SERP in such event.

          (b)  "Good  Reason"  shall  mean  the  occurrence  of  any of the
following (other than for "Cause"), without the Executive's express written
consent:  (i) the assignment to the Executive of duties  inconsistent  with
the Executive's  status as an executive  officer of COMSAT or a substantial
reduction  by COMSAT of the  Executive's  responsibilities  as an executive
officer of COMSAT;  (ii) any relocation of the Executive's  offices outside
the  Washington,  D.C.  metropolitan  area by  COMSAT  prior  to the  third
anniversary  of the Effective  Date;  or (iii) any material  default of the
provisions of Section 2 of this Agreement  which  continues for 20 business
days  following  COMSAT's  receipt of  written  notice  from the  Executive
specifying the manner in which COMSAT is in default of such provisions.  In
order for the  Executive to  terminate  employment  for "Good  Reason," the
Executive must give COMSAT written notice of his  termination of employment
for "Good Reason,"  stating the basis for the  termination,  within 90 days
after the  Executive  learns of the  occurrence  of the event  constituting
"Good Reason."

          (c) The  Executive's  employment  may be terminated by COMSAT for
Cause at any time upon 10 days written notice to the  Executive,  and after
giving the  Executive  an  opportunity  to discuss such  decision  with the
Board.  For  purposes  of this  Agreement,  COMSAT  shall  have  "Cause" to
terminate the Executive's  employment  hereunder upon (i) the continued and
deliberate  failure of the Executive to perform his material  duties,  in a
manner substantially consistent with the manner reasonably prescribe by the
Board and in accordance  with the terms of this  Agreement  (other than any
such  failure  resulting  from his  incapacity  due to  physical  or mental
illness),  which  failure  continues  for 20 business  days  following  the
Executive's  receipt of written notice from the Board specifying the manner
in which the  Executive  is in default of his duties,  (ii) the engaging by
the Executive in  intentional  serious  misconduct  that is materially  and
demonstrably injurious to COMSAT or its reputation, which misconduct, if it
is reasonably  capable of being cured, is not cured by the Executive within
20 business days following the  Executive's  receipt of written notice from
the Board  specifying the serious  misconduct  engaged in by the Executive,
(iii) the conviction of the Executive of commission of a felony, whether or
not such felony was committed in connection with COMSAT's business, or (iv)
any material breach by the Executive of Section 10 hereof, which breach, if
it is  reasonably  capable of being  cured,  is not cured by the  Executive
within 20 business days following the Executive's receipt of written notice
from the Board  specifying  the breach of Section 10 by the  Executive.  If
COMSAT shall terminate the Executive's  employment for "Cause," COMSAT,  in
full  satisfaction of all of COMSAT's  obligations under this Agreement and
in respect of the  termination of the  Executive's  employment with COMSAT,
shall  pay the  Executive  his  Base  Salary  and any  other  compensation,
benefits and  reimbursements due him under COMSAT plans through the date of
termination of his employment.

          (d) If, prior to the  expiration or termination of the Employment
Period,  the Executive shall have been unable to perform  substantially his
duties by reason of  disability  or  impairment  of health for at least six

                                    -5-


consecutive calendar months,  COMSAT shall have the right to terminate this
Agreement by giving 60 days written notice to the Executive to that effect,
but only if at the time such notice is given such  disability or impairment
is still  continuing.  Following the expiration of the notice  period,  the
Employment  Period shall terminate with the payment of the Executive's Base
Salary for the month in which  notice is given and a prorated  Annual Bonus
through such month.  In the event of a dispute as to whether the  Executive
is disabled within the meaning of this Section 5(d), or the duration of any
disability, either party may request a medical examination of the Executive
by a doctor  appointed  by the  Chief of Staff of a  hospital  selected  by
mutual agreement of the parties, or as the parties may otherwise agree, and
the written  medical opinion of such doctor shall be conclusive and binding
upon the parties as to whether the  Executive  has become  disabled and the
date when such disability arose. The cost of any such medical  examinations
shall be borne by COMSAT. In no event shall this Agreement terminate before
COMSAT's  long-term  disability  benefits  under  applicable  plans  become
payable to the Executive.

          (e) If, prior to the  expiration or termination of the Employment
Period, the Executive shall die, COMSAT shall pay to the Executive's estate
his Base Salary and a prorated Annual Bonus through the end of the month in
which the Executive's  death occurred,  at which time the Employment Period
shall terminate without further notice.

          (f) If either  the  Executive  or COMSAT  elects not to renew the
Executive's employment with COMSAT at the end of the Employment Period, the
Executive shall be entitled to receive payments under the SERP beginning on
May 1, 2002 (the  first  day of the  month  after the end of such  period),
calculated  in  accordance  with the  provisions  of the SERP  based on the
Executive's  retirement on that date,  provided that the Board reserves the
discretion to waive the applicable  early  retirement  reduction  under the
SERP in such event.  If the  Executive's  employment with COMSAT under this
Agreement  is  terminated  either by the  Executive  for Good  Reason or by
COMSAT  without  Cause before the  Executive  attains age 55, the Executive
shall be entitled to receive  payments under the SERP beginning on April 1,
2002 (the  first day of the month  after the  Executive's  55th  birthday),
calculated  in  accordance  with  the  provisions  of  the  SERP  as if the
Executive  retired  on that  date,  provided  that the Board  reserves  the
discretion to waive the applicable  early  retirement  reduction  under the
SERP in such event.  If the Executive dies before  payments begin under the
SERP, the  Executive's  surviving  spouse,  if any, shall receive under the
SERP a $200,000 lump sum death benefit,  plus annual benefit payments for a
ten year period equal to 50% of the  Executive's  accrued benefit under the
SERP,  according to the terms of the SERP.  The  provisions of this Section
5(f) shall be administered consistent with the terms of the SERP.

          (g) If  the  Executive  voluntarily  terminates  employment  with
COMSAT, such termination shall not be considered a breach of this Agreement
by the Executive and shall not adversely  affect the  Executive's  right to
receive such  benefits as may be payable to the Executive on account of his

                                    -6-

<PAGE>

termination  of employment  under  applicable  COMSAT plans.  The Executive
shall remain  obligated to comply with the  provisions of Sections 3, 4, 10
and 12 of this Agreement.

     6.   CHANGE  OF  CONTROL.  If a change  of  control  (as  defined  for
purposes of COMSAT's  benefit plans) occurs during the Employment Term, the
change of control shall not adversely affect any of the Executive's  rights
under this Agreement, and this Agreement shall continue in effect according
to its terms.  In the event of a change of control,  the Executive shall be
entitled to vesting and payment of benefits  according to the terms of this
Agreement or COMSAT's applicable plans, whichever is more favorable.

     7.   CERTAIN ADDITIONAL PAYMENTS.
          ---------------------------

          (a)  Notwithstanding  anything in this Agreement to the contrary,
in the event that it shall be determined that any payment or benefit to the
Executive,  whether pursuant to the terms of this Agreement or otherwise (a
"Payment"),  would  constitute  an "excess  parachute  payment"  within the
meaning of Section  280G of the Internal  Revenue Code of 1986,  as amended
(the "Code"), the Executive shall be paid an additional amount (a "Gross-Up
Payment")  such  that  the  net  amount  retained  by the  Executive  after
deduction of any excise tax imposed under Section 4999 of the Code, and any
federal,  state and local  income  and  employment  taxes and  excise  tax,
including any interest and penalties with respect thereto, imposed upon the
Gross-Up Payment shall be equal to the Payment. For purposes of determining
the amount of the Gross-Up  Payment,  the Executive  shall be deemed to pay
federal  income tax and  employment  taxes at the highest  marginal rate of
federal  income and  employment  taxation in the calendar year in which the
Gross-Up  Payment  is to be made and state and  local  income  taxes at the
highest  marginal  rate  of  taxation  in the  state  and  locality  of the
Executive's residence on the date the Payment is made, net of the reduction
in federal income taxes that the Executive may obtain from the deduction of
such state and local income taxes.

          (b) All  determinations  to be made under this Section 7 shall be
made by COMSAT's  independent  public  accountant  immediately prior to the
date the Payment is made (the "Accounting Firm"),  which firm shall provide
its determinations  and any supporting  calculations and workpapers both to
COMSAT  and  the  Executive   within  10  days  of  such  date.   Any  such
determination  by the Accounting  Firm shall be binding upon COMSAT and the
Executive.  Within  five  days  after  receipt  of  the  Accounting  Firm's
determination,  COMSAT  shall pay to the  Executive  the  Gross-Up  Payment
determined by the Accounting Firm.

          (c) In the  event  that upon any  audit by the  Internal  Revenue
Service, or by a state or local taxing authority,  of a Payment or Gross-Up
Payment,  a change is finally  determined  to be  required in the amount of
taxes paid by the Executive,  appropriate  adjustments  shall be made under
this  Section  such that the net amount  which is payable to the  Executive
after  taking into account the  provisions  of Section 4999 of the Code and
any  interest  and  penalties  shall  reflect  the  intent of the partie as
expressed  in  paragraph  (a)  above,  in  the  manner  determined  by  the

                                    -7-

<PAGE>


Accounting  Firm. The Executive shall notify COMSAT in writing of any claim
by the Internal  Revenue  Service  that, if  successful,  would require the
payment by COMSAT of a Gross-Up Payment.  Such notification  shall be given
as soon as  practicable  but no later  than ten  business  days  after  the
Executive is informed in writing of such claim and shall apprise  COMSAT of
the nature of such claim and the date on which such claim is requested to b
paid. The Executive shall not pay such claim prior to the expiration of the
30-day  period  following  the date on which it gives such notice to COMSAT
(or such shorter  period  ending on the date that any payment of taxes with
respect to such claim is due). If COMSAT  notifies the Executive in writing
prior to the  expiration  of such  period  that it desires to contest  such
claim,  the Executive  shall:  (i) give COMSAT any  information  reasonably
requested  by COMSAT  relating  to such  claim;  (ii)  take  such  action i
connection with contesting such claim as COMSAT shall reasonably request in
writing from time to time, including,  without limitation,  accepting legal
representation  with  respect  to  such  claim  by an  attorney  reasonably
selected  by COMSAT;  (iii)  cooperate  with  COMSAT in good faith in order
effectively to contest such claim; and (iv) permit COMSAT to participate in
any  proceedings  relating to such claim;  PROVIDED,  HOWEVER,  that COMSAT
shall bear and pay directly all costs and  expenses  (including  additional
interest and penalties)  incurred in connection with such contest and shall
indemnify and hold the Executive  harmless,  on an after-tax basis, for any
excise tax or income tax  (including  interest and  penalties  with respect
thereto)  imposed as a result of such  representation  and payment of costs
and  expenses.  Without  limitation  on the  foregoing  provisions  of this
Section 7, COMSAT shall control all  proceedings  taken in connection  with
such  contest  and,  at its sole  option,  may  pursue or forgo any and all
administrative  appeals,  proceedings,  hearings and  conferences  with the
taxing  authority in respect of such claim and may contest the claim in any
permissible manner, and the Executive agrees to prosecute such contest to a
determination  before any  administrative  tribunal,  in a court of initial
jurisdiction  and  in  one  or  more  appellate  courts,  as  COMSAT  shall
determine.  COMSAT's control of the contest shall be limited to issues with
respect to which a Gross-Up  Payment  would be  payable  hereunder  and the
Executive  shall be entitled to settle or contest,  as the case may be, any
other issue  raised by the  Internal  Revenue  Service or any other  taxing
authority.

          (d)  All of the  fees  and  expenses  of the  Accounting  Firm in
performing the  determinations  referred to in paragraphs (b) and (c) above
shall be borne  solely  by  COMSAT.  COMSAT  agrees to  indemnify  and hold
harmless the Accounting Firm from any and all claims,  damages and expenses
resulting from or relating to its determinations pursuant to paragraphs (b)
and (c) above,  except for claims,  damages or expenses  resulting from the
gross negligence or willful misconduct of the Accounting Firm.

     8.   SURVIVORSHIP.  The  respective  rights  and  obligations  of  the
parties   hereunder  shall  survive  any  termination  of  the  Executive's
employment and the Employment Term to the extent  necessary to the intended
preservation of such rights and obligations.


     9.   MITIGATION AND NO OFFSETS. The Executive shall not be required to
mitigate  the  amount  of any  payment  or  benefit  provided  for in  this
Agreement by seeking  other  employment  or otherwise and there shall be no

                                    -8-

<PAGE>


offset against amounts due the Executive under this Agreement on account of
any  remuneration  attributable  to any subsequent  employment  that he may
obtain.  COMSAT's  obligations  to make payments  under this  Agreement and
otherwise to perform its obligations hereunder shall not be affected by any
circumstances,  including,  without limitation, any set-off,  counterclaim,
recoupment,  defense  or other  right  which  COMSAT may have  against  the
Executive or others.

     10.  NON-COMPETITION.
          ---------------

          (a)  NON-COMPETITION  AGREEMENT.  As an inducement  for COMSAT to
enter  into  this  Agreement,   the  Executive  agrees  that,   during  the
Non-Competition Period (as defined below), the Executive shall not, without
the prior written consent of the Board, engage or participate,  directly or
indirectly,   as  principal,   agent,   employee,   employer,   consultant,
stockholder, partner or in any other individual capacity whatsoever, in the
conduct or management  of, or own any stock or any other equity  investment
in or debt  of,  any  business  which  is  competitive  with  any  business
conducted by COMSAT. The Non-Competition Period is the period commencing as
of the  Effective  Date  and  running  through  the  date  that is one year
following  the  date  on  which  the  Executive's  employment  with  COMSAT
terminates for any reason.

          (b) COMPETITIVE  BUSINESS.  For the purpose of this Agreement,  a
business shall be considered to be competitive  with any business of COMSAT
only if such  business is engaged in  providing  services  or products  (i)
comparable  to or  competitive  with (A) any  service or product  currently
provided by COMSAT during the Employment Period; (B) any service or product
which  evolves from or results  from  enhancements  in the ordinary  course
during the  Non-Competition  Period to the services or products provided by
COMSAT as of the date hereof or during the  Employment  Period;  or (C) any
future  service or product of COMSAT as to which the  Executive  materially
and substantially participated in the development or enhancement,  and (ii)
to customers,  distributors  or clients of the type served by COMSAT during
the Non-Competition  Period. Without limiting the foregoing,  employment of
the Executive by a law firm as a lawyer will not be  considered  employment
with a competitor for purposes of this Agreement.

          (c)  NON-SOLICITATION  OF EMPLOYEES.  During the  Non-Competition
Period,  the Executive  will not (for his own benefit or for the benefit of
any person or entity  other than COMSAT)  solicit,  or assist any person or
entity other than COMSAT to solicit,  any officer,  director,  executive or
employee (other than an administrative  or clerical  employee) of COMSAT to
leave his or her employment.


          (d) REASONABLENESS;  INTERPRETATION.  The Executive  acknowledges
and agrees,  solely for purposes of determining the  enforceability of this
Section 10 (and not for purposes of determining the amount of money damages
or for any  other  reason),  that (i) the  markets  served  by  COMSAT  are
national and international and are not dependent on the geographic location
of executive  personnel or the businesses by which they are employed;  (ii)

                                    -9-

<PAGE>


the  length  of the  Non-Competition  Period  is  linked to the term of the
Employment Period; and (iii) the above covenants are manifestly  reasonable
on their face, and the parties  expressly agree that such restrictions have
been  designed to be  reasonable  and no greater  than is required  for the
protection  of COMSAT.  In the event that the  covenants in this Section 10
shall be determined by any court of competent jurisdiction in any action to
be  unenforceable  by reason of their  extending  for too great a period of
time or over too great a geographical  area or by reason of their being too
extensive in any other  respect,  they shall be  interpreted to extend only
over the maximum period of time for which they may be  enforceable,  and/or
over the  maximum  geographical  area as to which  they may be  enforceable
and/or to the maximum  extent in all other respects as to which they may be
enforceable, all as determined by such court in such action.

          (e)  INVESTMENT.  Nothing  in this  Agreement  shall be deemed to
prohibit  the  Executive  from  owning  equity or debt  investments  in any
corporation,  partnership or other entity which is competitive with COMSAT,
provided that such  investments (i) are passive  investments and constitute
five percent or less of the outstanding equity securities of such an entity
the equity securities of which are traded on a national securities exchange
or other public market, or (ii) are approved by the Board.

     11.  INDEMNIFICATION;  LIABILITY  INSURANCE.  The  Executive  shall be
entitled to indemnification and coverage under COMSAT's liability insurance
policy for  officers  to the same extent as other  officers  of COMSAT.  In
addition,  the  Executive  shall  be  indemnified  to  the  maximum  extent
permitted by law of the jurisdiction in which COMSAT is incorporated, as it
may be amended from time to time.

     12.  ENFORCEMENT.
          -----------

          (a) The Executive  acknowledges that a breach of the covenants or
provisions  contained in Sections 3, 4 and 10 of this  Agreement will cause
irreparable  damage to COMSAT,  the exact amount of which will be difficult
to  ascertain,  and that the  remedies  at law for any such  breach will be
inadequate.  Accordingly,  the  Executive  agrees  that  if  the  Executive
breaches  or  threatens  to  breach  any of  the  covenants  or  provisions
contained  in  Sections 3, 4 and 10 of this  Agreement,  in addition to any
other remedy  which may be  available at law or in equity,  COMSAT shall be
entitled to seek specific  performance and injunctive  relief in a court of
competent jurisdiction after notice and a hearing.

          (b) The parties  expressly agree that any litigation  directly or
indirectly  arising  out of or  relating to this  Agreement,  including  an
action brought by COMSAT pursuant to this Section 12, shall be brought in a
court of competent jurisdiction in the State of Maryland.

     13.  EXPENSES OF ENFORCING THE AGREEMENT.  If the Executive  brings an
action to enforce any of the obligations of COMSAT under this Agreement and

                                   -10-

<PAGE>


prevails on any material  issue,  COMSAT shall pay the  Executive on demand
the amount  necessary to reimburse the Executive in full for all reasonable
expenses (including reasonable attorneys' fees and legal expenses) incurred
by the  Executive  in  enforcing  the  obligations  of  COMSAT  under  this
Agreement.


     14.  SEVERABILITY.   Should  any   provision  of  this   Agreement  be
determined to be  unenforceable  or prohibited by any applicable  law, such
provision  shall be ineffective to the extent,  and only to the extent,  of
such  unenforceability or prohibition  without  invalidating the balance of
such  provision  or any other  provision  of this  Agreement,  and any such
unenforceability or prohibition in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     15.  ASSIGNMENT.  The Executive's  rights and  obligations  under this
Agreement  shall not be assignable by the  Executive.  COMSAT's  rights and
obligations  under this Agreement  shall not be assignable by COMSAT except
as  incident  to  the  transfer,   by  merger  or  otherwise,   of  all  or
substantially  all of the  business  of  COMSAT.  In the  event of any such
assignment  by COMSAT,  all rights of COMSAT  hereunder  shall inure to the
benefit of the  assignee,  provided  that all  references  herein to COMSAT
shall be deemed to refer with equal  force and effect to any  corporate  or
other successor of COMSAT.

     16.  NOTICES.  All notices and other communications which are required
or may be given  under  this  Agreement  shall be in  writing  and shall be
deemed to have been duly given when received if personally delivered;  when
transmitted if transmitted by telecopy,  electronic or digital transmission
method,  provided  that in such case it shall also be sent by  certified or
registered  mail,  return receipt  requested;  the day after it is sent, if
sent for next day delivery to a domestic  address by  recognized  overnight
delivery  service (E.G.,  Federal  Express);  and upon receipt,  if sent by
certified or registered mail,  return receipt  requested.  Unless otherwise
changed by notice, in each case notice shall be sent to:

     17.  MISCELLANEOUS.  This Agreement  constitutes the entire agreement,
and supersedes all prior agreements,  of the parties hereto relating to the
subject  matter  hereof,  and  there  are  no  written  or  oral  terms  or
representations  made by either party other than those contained herein. No
amendment,  supplement,  modification  or waiver of this Agreement shall be
binding unless  executed in writing by the party to be bound  thereby.  The

herein are for reference  purposes only and shall not in any way affect the
meaning or interpretation  of this Agreement.  The waiver by any party of a
breach of any term or condition of this  Agreement by the other party shall

thereof  or a waiver  of a breach  of any other  term or  condition  o this
Agreement.  This Agreement may be signed in two or more counterparts,  each
of which shall  constitute an original but all of which together shall form
