     Notes to Condensed Consolidated Financial Statements (Unaudited)


1.       Financial Statement Presentation

         These  financial   statements   include  the  accounts  of  COMSAT
Corporation   and   its   majority-owned   subsidiaries   (COMSAT   or  the
"corporation")  and  reflect  all  adjustments  that are, in the opinion of
management, necessary to fairly present the results of the periods covered.

2.       INTELSAT and Inmarsat Share Changes

         The  corporation's  ownership share of INTELSAT has decreased from
20.1% at December  31, 1994 to 19.1% as of June 30, 1995.  The  corporation
received cash  proceeds of $17.1 million and has a $0.5 million  receivable
for the balance due.

         The  corporation  paid  $9.0  million  to  increase  its  share in
Inmarsat from 22.4% at December 31, 1994 to 24.0% as of June 30, 1995.

3.       Inventories

         Inventories,  stated at the lower of cost (first-in, first-out) or

</TABLE>

4.       Investments

         In 1995 the  corporation  invested  $12.8 million in a new company
that will own and operate a satellite system  affiliated with Inmarsat (see
Note 8 to the 1994 financial  statements).  This includes the corporation's
$2.0  million  cash  investment  plus $9.4 million paid to Inmarsat for the
corporation's  share  of  Inmarsat's  cash  investment  in the  venture  in
addition to the corporation's $1.4 million share of a non-cash contribution
made by Inmarsat.

5.       Debt

         In  February  1995,  INTELSAT  issued  $200.0  million  of  8.125%
Eurobond  notes due  February  28,  2005.  Interest is payable  annually in
arrears. The corporation has recorded its share of this long-term debt.


Page 5
<PAGE>


         The  corporation  has issued  four notes  during the first half of
1995 under its  medium-term  note  program.  A $5.0  million  8.5% note was
issued in February  1995,  a $12.0  million  7.92% note was issued in March
1995 and a $9.0  million  7.77%  note and a $16.0  million  7.7%  note were
issued in May 1995.  These notes are due in 2007. The corporation has $26.0
million remaining under its medium-term note program.

6.       Nonrecurring Transactions

         In May 1995, the National  Basketball  Association  (NBA) approved
the admission of two expansion teams into the NBA.  Revenues for the second
quarter of 1995  include  the Denver  Nuggets'  $8.8  million  share of the
expansion  fees ($125  million  per team).  Approximately  one half of this
amount was received in cash in June 1995 and the corporation has recorded a
note receivable for the remainder.  The note is due upon the earlier of (1)
the completion of a collective bargaining agreement between the players and
the NBA or (2) May 1, 1996.

         Cost of services  for the second  quarter of 1995  includes a $3.3
million credit for  Inmarsat-related  costs which were over-accrued  during
1994 and the first quarter of 1995. Cost of services for the second quarter
of 1995 also includes a $2.7 million benefit plan  curtailment gain related
to the reduction of pension benefits and the elimination of  postretirement
health care benefits for a group of employees.

7.       Litigation

         As  discussed  in  Note  9 to  the  corporation's  1994  financial
statements,  the  corporation  is engaged in an antitrust suit filed by Pan
American  Satellite  (PanAmSat).  Discovery  in the suit ended in  November
1994; however, PanAmSat has motions pending which, if granted, would result
in additional  discovery.  In December 1994, the corporation filed a motion
for summary judgment  directed to dismissal of all claims in the complaint.
PanAmSat has opposed the motion. A hearing on the motion was held in a U.S.
District Court on August 3, 1995. In the opinion of management,  the claims
are without  merit,  and the ultimate  disposition  of this matter will not
have a material effect on the corporation's financial statements.

         The   corporation  has  been  defending  a  patent  and  copyright
infringement  suit brought by  Spectradyne,  Inc.  against its COMSAT Video
Enterprises,  Inc. and On Command Video Corporation  (OCV)  subsidiaries as
discussed in Note 9 to the 1994  financial  statements.  In June 1995,  all
claims related to this suit were dismissed.

8.       Subsequent Events

         On July 1, 1995, the corporation acquired a National Hockey League
(NHL)  franchise and related  player  contracts,  management  contracts and
certain other assets from Le Club de Hockey Les Nordiques in Quebec, Canada
for approximately $75 million. The franchise, which was known as the Quebec
Nordiques,  is being  relocated  to Denver,  Colorado  for the  1995-96 NHL
season and will be known as the Colorado  Avalanche.  The  acquisition  was
financed with the proceeds of a bank loan.

Page 6
<PAGE>

         In July  1995,  COMSAT  Capital  I, L.P.  issued  $200  million of
Monthly Income  Preferred  Securities  (MIPS).  COMSAT Capital I, L.P. 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 an  annual  dividend  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.  The proceeds have been used
to repay commercial paper borrowings and the $75 million bank loan incurred
in the acquisition of the NHL franchise and related assets.

         COMSAT  Capital  I, L.P.  will be  consolidated  in the  financial
statements of COMSAT  beginning  with the third  quarter of 1995.  The loan
between the partnership and COMSAT will be eliminated in consolidation. The
$200 million of MIPS will be presented on the consolidated balance sheet as
a minority interest.

         In July 1995,  the  corporation  announced  plans,  subject to FCC
review,  to integrate its mobile  communications  businesses  with COMSAT's
other international  communications  services  businesses.  The corporation
also announced that it has retained  investment counsel to evaluate ways to
unlock  the  value  of the  corporation's  entertainment  assets,  to raise
capital   specifically  to  fund  entertainment  growth  opportunities  and
potentially to monetize a portion of COMSAT's investment in these assets.

         In August 1995, the corporation increased its ownership percentage
in  OCV  to   approximately   85%  through  the   contribution  to  OCV  of
substantially  all of the corporation's  other hotel in-room  entertainment
assets.

         The  corporation  plans to  record a  restructuring  charge in the
third  quarter of 1995  related to the  integration  of its  communications
businesses and restructuring of its hotel in-room entertainment businesses.

Item 2.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
CONDITION AND RESULTS OF OPERATIONS FOR THE QUARTER 
ENDED JUNE 30, 1995


ANALYSIS OF OPERATIONS

Consolidated Operations

         Consolidated  revenues for the second  quarter of 1995 were $210.8
million,  an increase of $3.0 million over last year's second quarter.  The
International  Communications  and  Entertainment  segments  reported solid
growth in revenues whereas  Technology  Services segment revenues fell from
last year's second quarter.  Mobile  Communications  segment  revenues were
even with last year's second  quarter.  Revenues for the second  quarter of
1995 include the  corporation's  $8.8 million share of National  Basketball
Association  expansion fees. Last year's second quarter  revenues  included
$4.8 million of business interruption insurance income as discussed in Note
15 to the 1994 financial statements.

         Year-to-date  revenues were $418.7  million,  an increase of $10.4
million over the same period last year. The  International  Communications,
Mobile  Communications  and  Entertainment  segments all  reported  revenue
growth during this period,  whereas  Technology  Services  segment revenues
were lower than last year.

         Operating income increased $3.0 million from the second quarter of
1994. The Mobile Communications and Entertainment  segments reported growth
in operating income offset by lower operating results for the International
Communications and Technology Services segments. The NBA expansion revenues
contributed directly to operating income as there were no related operating
expenses.  This year's second  quarter also includes a $3.3 million  credit
for  Inmarsat-related  costs  which were  over-accrued  during 1994 and the
first  quarter of 1995 and a $2.7  million  benefit plan  curtailment  gain
resulting  from the reduction of pension  benefits and the  elimination  of
postretirement  health care benefits for a group of  employees.  The second
quarter of 1994 included a $4.3 million  charge ($4.1 million after tax, or
$0.08 per share) for merger  and  integration  costs  related to the merger
with Radiation Systems, Inc.

         Operating income for the first half of 1995 decreased $4.1 million
as compared to the same period last year. The Mobile Communications segment
reported  solid growth in operating  income.  The other  segments  reported
lower results this year.

         Interest  and other  income  increased  $0.3 million in the second
quarter of 1995,  and $1.1 million in the first half of 1995 as compared to
the same  periods  last year.  This year's  first  quarter  includes a $2.2
million   gain  from  the  sale  of  the   corporation's   interest   in  a
communications  venture in Chile  offset by a $0.9  million  accrual  for a
judgment in a lawsuit  brought by a former  employee of a subsidiary of the
corporation.

Page 8
<PAGE>

         Net interest expense for the second quarter increased $5.4 million
over last year's  second  quarter and  year-to-date  net  interest  expense
increased $8.1 million over the first half of 1994. These increases are due
to  increases  in  borrowings  and  interest  rates and  lower  capitalized
interest.   The  corporation's   borrowings  have  grown  to  meet  capital
expenditure and investment requirements. Interest capitalized, primarily on
satellite  construction  projects,  has declined due to the  completion  of
several  INTELSAT  satellites in the second half of 1994 and the first half
of 1995.

Segment Operating Results

         As  discussed  in Note 15 to the 1994  financial  statements,  the
corporation  reports  operating  results  in four  segments:  International
Communications,   Mobile   Communications,   Entertainment  and  Technology
Services.  The method of allocating indirect corporate costs was changed in
1995.  Segment  operating  results  for 1994  have been  restated  for this
change.

International Communications

         The International  Communications  segment includes the results of
COMSAT World Systems (CWS) and COMSAT  International  Ventures (CIV). CWS's
second  quarter  revenues  increased  $2.0 million over last year's  second
quarter.  Year-to-date  revenues  for CWS  increased  $3.0 million over the
first half of 1994.  These  improvements  were  primarily  attributable  to
growth in digital circuits and the corporation's share of INTELSAT revenues
which more than offset rate reductions  under long-term  agreements.  CIV's
second  quarter  revenues grew $5.3 million and its  year-to-date  revenues
grew $11.0 million over the same periods last year.  Approximately  half of
this growth came from improved results for the  corporation's  subsidiaries
in  Argentina  and  Brazil.  The  balance  of the  revenue  improvement  is
primarily attributable to a subsidiary which was not consolidated until the
fourth quarter of 1994.

Page 9
<PAGE>

         Operating income for the segment declined $4.1 million in both the
second  quarter and the first half of 1995 as compared to the same  periods
last year. CWS's operating expenses for last year's second quarter included
its $2.7 million share of a credit to pension expense recorded by INTELSAT.
Absent this  adjustment,  CWS's operating  income increased $1.5 million in
the second quarter and increased $3.5 million in the first half of the year
relative to the same periods in 1994.  These  changes are  primarily due to
the  increase  in  revenues  and a decline  in  operating  expenses  offset
somewhat by higher depreciation.  The decline in operating expenses was due
in part to a reduction  in staff late last year and other cost  containment
measures.  The  increase  in  depreciation  was  due to five  new  INTELSAT
satellites  that were  launched  and  placed in  service  in  1994 and  the
first half of this year.  CIV's  operating  income fell $2.9 million in the
second  quarter and $4.9 million in the first half of 1995 primarily due to
the operating losses for the newly consolidated subsidiary.

Mobile Communications

         Mobile  Communications  segment second quarter  revenues were even
with last year's  second  quarter.  Year-to-date  revenues  increased  $3.1
million  over  the same  period  last  year  primarily  due to a growth  in
Inmarsat-C  data services and the provision of additional  space segment to
AMSC and IDB.  These  improvements  were  partially  offset by a decline in
telephone revenues due to traffic shifts from higher-priced analog services
to  lower-priced  digital  services.  However,  overall  telephone  traffic
increased  approximately  7% this year versus the first half of 1994,  with
more than 6,800 digital standard M and B terminals now commissioned.

         Second  quarter   operating  income  increased  $6.6  million  and
year-to-date  operating income increased $7.7 million over the same periods
in 1994.  These increases are largely due to a $3.3 million credit recorded
in the  second  quarter  of 1995  for  Inmarsat-related  costs  which  were
over-accrued during 1994 and the first quarter of 1995. Additionally,  both
the quarter and the year-to-date  periods benefited from an increased share
of Inmarsat  operating  results.  The  corporation  increased its ownership
share of Inmarsat  from 22.4% at December  31, 1994 to 24.0% as of June 30,
1995. Operating margins from the improvement in revenues for the first half
of the year  also  contributed  to the  year-to-date  growth  in  operating
results.  All  of  these  improvements  were  partially  offset  by  higher
depreciation  expense  related to upgrades to earth  stations  and a higher
share of Inmarsat's depreciation expense.

Entertainment

         Second quarter revenues for the  Entertainment  segment  increased
$10.8 million and year-to-date revenues increased $17.8 million as compared
to the same  periods  last year.  Revenues  for the second  quarter of 1995
include  the  corporation's  $8.8  million  share  of  NBA  expansion  fees
discussed in Note 6 to the accompanying financial statements. The remainder
of the revenue improvement is primarily  attributable to increased revenues
from the On Command  Video  (OCV)  business  which more than  offset  lower
revenues for the Satellite Cinema  business.  The number of rooms installed
with the OCV system  increased by 121,000  rooms from June 30,  1994,  to a
total  of  323,000  at June 30,  1995.  An  additional  119,000  rooms  are

Page 10
<PAGE>

scheduled for OCV system  installation,  including  23,000 Satellite Cinema
rooms  scheduled for  conversion.  The revenue  improvements  for the hotel
in-room  entertainment  business were  partially  offset by lower  reported
revenues from the NBC television  distribution contract.  Revenues recorded
for this  contract  have  dropped by $2.9  million per quarter  because the
contract has entered an option period.

     Operating income for this segment increased $0.9 million in the second
quarter versus last year's second quarter,  whereas  operating  income fell
$4.9 million in the first six months of the year compared to the first half
of 1994.  The NBA  expansion  revenues  contributed  directly to  operating
income as there were no related  operating  expenses.  Absent the expansion
revenues,  operating  results  decreased  due to  declining  margins in the
Satellite Cinema business,  the reduction in reported revenues from the NBC
contract  and  due  to  overhead  costs  for  Beacon  Communications  Corp.
(Beacon).  The corporation acquired Beacon in December 1994 as discussed in
Note 6 to the 1994 financial statements. Beacon overhead costs have totaled
approximately $2.0 million per quarter.

Technology Services

         Revenues  for  the  Technology  Services  segment  declined  $13.5
million in the second  quarter of 1995 and $22.0  million in the first half
of 1995 as compared to the same periods last year.  Revenues increased this
year from satellite services for classified government users, earth station
component  sales and  Intelesys,  a VSAT  manufacturer  acquired in January
1995.  These  revenue  improvements  were more  than  offset by the lack of
recurring  revenues from several large  international  and U.S.  Government
projects  which were completed in 1994 and delays in sales of microwave and
cellular antennas. Additionally, the second quarter of 1994 included a $4.8
million insurance settlement.

         Operating  income was down $3.3  million and $5.5  million for the
second  quarter  and first half of 1995,  respectively,  as compared to the
same periods last year. These declines were primarily due to lower revenues
and to new product  development  costs  associated  with the newly acquired
VSAT  business.  Additionally,  operating  income  for this  year's  second
quarter  includes a $2.7 million credit for a benefit plan curtailment gain
related  to the  reduction  of  pension  benefits  and the  elimination  of
postretirement health care benefits for a group of employees.  Revenues and
operating income were lower than expected due to the cancellation late last
year of an $18 million contract for satellite earth stations in Kuwait.

Outlook

         In July 1995,  the  corporation  announced  plans,  subject to FCC
review,  to integrate its mobile  communications  businesses  with COMSAT's
other international  communications  services  businesses.  The corporation
also announced that it has retained  investment counsel to evaluate ways to
unlock the value of the company's  entertainment  assets,  to raise capital
specifically to fund entertainment  growth opportunities and potentially to
monetize a portion of COMSAT's investment in these assets.

Page 11
<PAGE>

         In August 1995, the corporation increased its ownership percentage
in  OCV  to   approximately   85%  through  the   contribution  to  OCV  of
substantially  all of the corporation's  other hotel in-room  entertainment
assets.

         The  corporation  plans to  record a  restructuring  charge in the
third  quarter of 1995  related to the  integration  of its  communications
businesses and restructuring of its hotel in-room entertainment businesses.

         The  corporation  expects  that the  results  for CWS will  remain
strong  for  the  remainder  of 1995  although  quarterly  results  will be
slightly  less than this year's first two  quarters.  CIV will  continue to
seek new investment  opportunities in emerging countries and to utilize the
corporation's  expertise to market a variety of products and services.  CIV
will  also  concentrate  on  the  growth  of  its  existing   ventures  and
anticipates  improvement  in  revenues  and  operating  results  from these
businesses.

         The  corporation  expects to continue to face  competition  in its
Mobile  Communications  business,  however, the continued  commissioning of
digital terminals should sustain the growth in digital traffic. At the same
time,  the  corporation  is making  progress on developing new products and
services through its Mini-M and I-CO programs .

     In the Entertainment segment, OCV will continue to install its systems
in hotel rooms which will boost revenues and increase  depreciation expense
for the remainder of the year.  Beacon is expected to release a new film in
the third  quarter.  The  corporation  plans to  construct a new sports and
entertainment complex in Denver, Colorado. Arrangements for the complex are
not yet  complete,  therefore,  groundbreaking  will be delayed  which will
delay the opening of the complex beyond the start of the 1997-98 season. On
July 1, 1995,  the  corporation  acquired a National  Hockey  League  (NHL)
franchise  and related  assets as discussed  in Note 8 to the  accompanying
financial  statements.  The NHL franchise is expected to make a significant
contribution to revenues of the  Entertainment  segment,  but will probably
negatively  impact  operating  results  in the near  term.  The NBA has not
reached a ratified collective bargaining agreement with its players and the
players' union may be decertified as the bargaining  agent for the players.
If no collective  bargaining  agreement is reached, the NBA may cancel some
or all of the 1995-96 season,  which could  adversely  affect the financial
results of the Entertainment segment.

         In the  Technology  Services  segment,  the  corporation  has been
successful  in winning new  contracts  this year and expects to continue to
build its contract backlog throughout the rest of the year.

LIQUIDITY AND CAPITAL RESOURCES

         The  primary  sources of cash in the  second  quarter of 1995 were
operations,   borrowings   and  proceeds  from  the  decrease  in  INTELSAT
ownership.   Cash  was  expended  primarily  for  property  and  equipment,
investments in businesses,  acquisition of additional  Inmarsat  ownership,
repayment of long-term debt and quarterly dividends.

Page 12
<PAGE>

         The  corporation's  working  capital  deficit of $18.8  million at
December 31, 1994 improved to positive  working capital of $11.5 million at
June 30, 1995.  This  improvement is primarily due to decreases in accounts
payable,  accrued  liabilities and amounts due to related parties partially
offset by  increases  in  commercial  paper  borrowings  and other  current
liabilities.  Accounts payable and accrued liabilities  decreased primarily
because of a reduction in deferred  revenues related to the Denver Nuggets.
Receipts  for season  tickets and  sponsorship  agreements  are recorded as
deferred revenues and recognized as games are played. Additionally, accrued
liabilities  at December  31, 1994  included an accrual for a $9.1  million
payment in February 1995 to terminate the corporation's lease on its former
headquarters  building in  Washington,  D.C.  Amounts  due related  parties
decreased  primarily due to a larger than normal payment to Inmarsat in the
first quarter for the corporation's  share of satellite  utilization costs.
The increase in other current  liabilities is primarily due to income taxes
accrued for the first half of 1995.

         In February 1995,  INTELSAT issued $200.0 million of 8.125% notes.
The  corporation  has recorded its share of these notes as long-term  debt.
The corporation  received  approximately  $20.1 million of its share of the
proceeds and used this amount to repay commercial paper. The balance of the
proceeds was retained by INTELSAT for the corporation's  share of satellite
construction costs.

         The  corporation  has access to short- and long-term  financing at
favorable rates. The  corporation's  borrowing  activities are regulated by
the Federal Communications Commission. As of June 30, 1995, the corporation
had $130.9  million in  commercial  paper  borrowings  under a $200 million
commercial paper program.

         As discussed  in Note 7 to the 1994  financial  statements  and to
Note 5 to the accompanying financial statements, the corporation has a $100
million  "medium-term  note  program."  The  corporation  has issued  $74.0
million of notes under this program.  The proceeds of these notes have been
used to repay commercial paper.

         In July  1995,  COMSAT  Capital  I, L.P.  issued  $200  million of
Monthly Income  Preferred  Securities  (MIPS).  COMSAT Capital I, L.P. 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 an  annual  dividend  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  covenants.  The proceeds have been used to repay
commercial  paper  borrowings and the $75 million bank loan incurred in the
acquisition of the Nordiques.

          (a) The General  Partner  has,  on or prior to the Closing  Date,
contributed  an  aggregate of $100 to the capital of the  Partnership.  The
General  Partner  shall,  on or  prior  to  the  Closing  Date,  make  such
additional capital  contribution as is necessary for the General Partner to
have  contributed  an  aggregate  of 3% of the capital  contributed  by all
Partners as of the Closing Date.

          (b) The Initial  Limited  Partner has,  prior to the date hereof,
contributed  the amount of $100 to the  capital of the  Partnership,  which
amount will be returned to the Initial  Limited  Partner as contemplated by
Section 2.9(b).

          (c) On the Closing  Date,  each  Person who  acquires a Preferred
Security  from  the  Partnership   shall,  as  the  consideration  for  the
acquisition  of such Preferred  Security,  contribute to the capital of the

Preferred Security.

          (d) No Limited  Partner shall at any time be required to make any
additional  capital  contributions  to the  Partnership,  except  as may be
required by law.

          Section 3.2 Preferred  Security Holder's Interest  Represented by
LP Certificate. A Preferred Security Holder's Interest shall be represented
by the LP Certificate  held by or on behalf of such Holder.  Each Preferred
Security Holder's respective ownership of Preferred Securities shall be set
forth on the books and  records  of the  Partnership.  Each  Holder  hereby
agrees that its Interest  represented by its LP  Certificate  shall for all
purposes be personal  property.  A Preferred  Security Holder shall have no
interest in specific Partnership property.

          Section 3.3 Capital  Accounts.  An individual  capital account (a
"Capital  Account") shall be established and maintained on the books of the
Partnership for each Partner in compliance with Treasury  Regulation ss.ss.
1.704-1(b)(2)(iv)  and  1.704-2,  as  amended.  Subject  to  the  preceding
sentence,  each  Capital  Account  will be  increased  by the amount of the
capital  contributions  (including the Purchase Price) made by, and the Net
Income  allocated to, such Partner (or predecessor in interest) and reduced
by the  amount of  distributions  made by the  Partnership,  and Net Losses
allocated, to the Partner (or

                                   -10-

predecessor  thereof).  In addition,  a Partner's Capital Account
shall  be  increased  or  decreased,  as the  case  may be,  for any  items
specially  allocated to such Partner under  Section 4.2 of this  Agreement,
and, to the extent  permitted under such Treasury  Regulation,  the General
Partner's  Capital  Account  will be  increased  to the extent the  General
Partner pays any costs or expenses of the  Partnership  directly out of the
General Partner's own funds.

          Section 3.4 Interest on Capital Contributions. Except as provided
herein,  no Partner shall be entitled to interest on or with respect to any

                                ALLOCATIONS

          Section  4.1  Profits  and  Losses.  After  giving  effect to the
special allocations set forth in Section 4.2,

          (a) the  Partnership's  Net Income for each Fiscal  Period of the
Partnership shall be allocated as follows:

          (i) First,  to each  Holder,  as of the close of  business on the
record date for such Fiscal  Period,  an amount of Net Income  equal to the
excess of (x) the Dividends accrued on such Holder's  Preferred  Securities
from the Closing  Date through and  including  the close of business on the
record date for such Fiscal  Period,  including  any  Additional  Dividends
payable with respect  thereto,  over (y) the amount of Net Income allocated
to each such  Holder (or  predecessor  thereof)  pursuant  to this  Section
4.1(a)(i) in all prior Fiscal Periods,  including any Additional  Dividends
payable with respect thereto.

          (ii) Second,  to each Holder,  as of the close of business on the
record date for such Fiscal  Period,  an amount of Net Income  equal to the
excess of (x) all Net Losses  allocated to each such Holder (or predecessor
thereof)  from  the date of  issuance  of each of such  Holder's  Preferred
Securities  through and including the close of such Fiscal Period  pursuant
to Section 4.1(b)(ii) over (y) the amount of Net Income allocated

                                   -11-

<PAGE>



to such Holder (or predecessor  thereof) pursuant to this Section
4.1(a)(ii) in all prior Fiscal Periods.

          (iii) Any  remaining Net Income shall be allocated to the General
Partner.

          (b) The  Partnership's  Net Loss for any Fiscal  Period  shall be
allocated as follows:

          (i)  First,  to the  General  Partner  until the  balance  of the
General Partner's Capital Account is reduced to zero.

          (ii) Second,  among the Holders in proportion to their respective
aggregate Capital Account  balances,  until the Capital Account balances of
such  Holders  are  reduced to zero;  provided,  however,  that the General
Partner  shall  make  appropriate  adjustments  in  these  allocations,  in
accordance with Section 4.1(c), with respect to any Preferred Securities as
to which Net Income has been  allocated  with  respect  to  Dividends  that
accrued but were not paid.

          (iii) Any  remaining  Net Loss shall be  allocated to the General
Partner.

          (c)  The  General   Partner   shall  make  such  changes  to  the
allocations in Sections 4.1(a) and 4.1(b) as it deems reasonably  necessary
so  that,  in the  year of the  Partnership's  dissolution,  winding-up  or
termination,  amounts  distributed  to the  Preferred  Security  Holders in
accordance  with Section  11.4(a)  shall equal the  aggregate of the stated
liquidation preference of $25 per Preferred Security and accrued and unpaid
Dividends  to the  date of  payment,  including  any  Additional  Dividends
accrued thereon (the  "Liquidation  Distribution"),  unless,  in connection
with such dissolution,  winding-up or termination,  Subordinated Debentures
in a principal amount equal to the aggregate liquidation  preference of the
Preferred  Securities  have  been  distributed  on a pro rata  basis to the
Holders.

         Section 4.2  Special Allocations.

          (a) All expenditures  described in Code Section  705(a)(2)(B) and
Section 9.3 hereof that are incurred  by, or on behalf of, the  Partnership
shall be allocated entirely to the General Partner.

          (b)  In  the  event  any   Holder   unexpectedly   receives   any
adjustments,  allocations or distributions described in Treasury Regulation
ss.  1.704-1(b)(2)(ii)(d)(4),  (5) or (6), items of Partnership  Net Income
shall be  specially  allocated  to such  Holder  in an  amount  and  manner
sufficient to elimi-


                                   -12-

<PAGE>



nate,  to the extent  required by the Treasury  Regulations,  the
deficit,  if any, in the  balance of the Capital  Account of such Holder as
quickly as  possible.  This  Section  4.2(b) is intended to comply with the
qualified  income  offset  provision  in  ss.  1.704-1(b)(2)(ii)(d)  of the
Treasury Regulations.

          (c) For purposes of determining the profits,  losses or any other
items  allocable  to any period,  profits,  losses and any such other items
shall be  determined on a daily,  monthly or other basis,  as determined by
the General  Partner using any method that is permissible  under ss. 706 of
the Code and the Treasury  Regulations  promulgated  thereunder.  Unless
otherwise  specified,   such  profits,  losses  or  other  items  shall  be
determined for each Fiscal Period.

          (d)  The  Partners  and  Holders,  by  becoming  parties  to this
Agreement,  either by execution  hereof or pursuant to Section 2.9, will be
deemed to be aware of the income tax  consequences of the allocations  made
by this  Article  IV and will be deemed  to have  agreed to be bound by the
provisions of this Article IV in reporting  their shares of Partnership Net
Income and Net Loss for U.S. federal income tax purposes.

          (e)  Notwithstanding   anything  to  the  contrary  that  may  be
expressed  or  implied in this  Article  IV, the  interest  of the  General
Partner in each item of income,  gain,  loss,  deduction and credit will be
equal to at least (i) at any time that aggregate  capital  contributions to
the Partnership are equal to or less than $50,000,000, 1% of each such item
and  (ii)  at  any  time  that  aggregate  capital   contributions  to  the
Partnership are greater than $50,000,000,  1% of each such item, multiplied
by a fraction (not  exceeding one and not less than 0.2),  the numerator of
which is  $50,000,000  and the  denominator  of which is the  lesser of the
aggregate  Capital Account balances of the Capital Accounts of all Partners
at such time and the aggregate capital  contributions to the Partnership of
all Partners at such time.

          (f) The Partners  intend that the  allocations  under Section 4.1
conform to Treasury  Regulations ss.ss.  1.704-1(b) and 1.704-2 (including,
without  limitation,  the minimum gain  chargeback,  chargeback  of partner
nonrecourse  debt  minimum  gain,   qualified  income  offset  and  partner
nonrecourse  debt  provisions  of such  Treasury  Regulations),  and the
General  Partner shall make such changes in the  allocations  under Section
4.1 as it believes are reasonably necessary to meet the  requirements  of
such Treasury Regulations.

          (g) Solely for the purpose of adjusting  the Capital  Accounts of
the Partners,  and not for tax purposes,  if any property is distributed in
kind to any Partner,  the difference  between its fair market value and its
book  value at the time of  distribution  shall be  treated as gain or loss
recognized by the Partnership  and allocated  pursuant to the provisions of
Section 4.1.

          (h) In the event of a Code Section 708(b)(1)(B) termination, or a
pro rata liquidating  distribution of the Subordinated  Debentures pursuant
to  Section  11.4  hereof,  the  fair  market  value  of  the  Subordinated
Debentures  held by the  Partnership  shall be deemed  to be the  principal
amount thereof.

          Section  4.3  Allocations  for Income Tax  Purposes.  The income,
gains, losses, deductions and credits of the Partnership shall be allocated
in the same manner as the items entering into the computation of Net Income
and Net Loss are allocated under Sections 4.1 and 4.2;  provided,  however,
that solely for federal, state and local income and franchise tax purposes,
but not for  book or  Capital  Account  purposes,  income,  gain,  loss and
deductions   with  respect  to  any  property   properly   carried  on  the
Partnership's  books at a value  other than the tax basis of such  property
shall  be  allocated  in a  manner  determined  in  the  General  Partner's
discretion,  so as to take into  account  (consistently  with Code  Section
704(c)  principles)  the difference  between such property's book value and
its tax basis.  Notwithstanding  anything to the contrary set forth in this
Agreement,  the General  Partner is authorized to modify the allocations of
this Section 4.3, and Sections 4.1 and 4.2, if necessary or appropriate, in
the  General  Partner's  sole  discretion,  for the  allocations  to fairly
reflect the economic  gain,  income or loss to each of the Partners,  or as
otherwise required by the Code or the Treasury Regulations.

          Section  4.4  Withholding.  The  Partnership  shall  comply  with
withholding requirements under federal, state and local law and shall remit
amounts withheld to and file required forms with applicable  jurisdictions.
To the extent that the Partnership is required to withhold and pay over any
amounts to any authority  with respect to  distributions  or allocations to
any Partner,  the amount  withheld shall be deemed to be a distribution  in
the amount of the  withholding to the Partner.  In the event of any claimed
over-withholding,  Partners  shall be limited to an action  against  the
applicable  jurisdiction.  If the amount  withheld  was not  withheld  from
actual distributions,  the Partnership may reduce subsequent  distributions
by the amount of such withholding.  Each  Partner  agrees to furnish the
Partnership with any representations and forms as shall reasonably be

                                   -14-

<PAGE>



requested  by the  Partnership  to assist it in  determining  the
extent of, and in fulfilling, its withholding obligations.

                        DIVIDENDS AND DISTRIBUTIONS

          Section 5.1 Dividends.  Limited  Partners shall receive  periodic
Dividends,  if any, Additional  Dividends,  if any, redemption payments and
liquidation  distributions  in  accordance  with the terms of the Preferred
Securities  set forth in Article VI. Subject to the rights of the Preferred
Security  Holders,  all remaining  cash shall be distributed to the General
Partner at such time as the General Partner shall determine.

          Section 5.2 Limitations on  Distributions.  The Partnership shall
not  make a  distribution  to any  Partner  on  account  of such  Partner's
Interest if such  distribution  would violate  Section 17-607 of the Act or
other applicable law.

                                ARTICLE VI

                     ISSUANCE OF PREFERRED SECURITIES

          Section 6.1 General Provisions Regarding Preferred Securities.

          (a) There is hereby  authorized  for issuance and sale  Preferred
Securities  having an  aggregate  liquidation  preference  not greater than
$200,000,000 and having the designation,  annual Dividend rate, liquidation
preference,  redemption  terms and other  powers,  preferences  and special
rights and limitations set forth in this Article VI.

          (b) The payment of Dividends,  Additional Dividends,  if any, and
payments  of   distributions  by  the  Partnership  in  liquidation  or  on
redemption in respect of Preferred Securities shall be guaranteed by COMSAT
pursuant to, and to the extent  provided in, the  Guarantee.  The Guarantee
constitutes  a  guarantee  of payment  and not of  collection.  The Holders
hereby authorize the General Partner to hold the Guarantee on behalf of the
Holders.  In  the  event  of an  appointment  of a  Special  Representative
pursuant to Section  6.2(f) to, among other  things,  enforce the rights of
the  Holders  under the  Guarantee,  the  Special  Representative  may take
possession of the Guarantee for such purpose. If no Special  Representative
has been  appointed to enforce the Guarantee,  the General  Partner has the
right to enforce the Guarantee on behalf of the Holders. The Holders

                                   -15-

<PAGE>



of not less than 10% in aggregate  liquidation  preference of all
outstanding  Preferred Securities have the right to direct the time, method
and place of conducting any proceeding for any remedy  available in respect
of the Guarantee, including the giving of directions to the General Partner
or the Special  Representative,  as the case may be. If the General Partner
or the Special  Representative  fails to enforce the  Guarantee as provided
above,  a Holder may  institute  a legal  proceeding  directly  against the
guarantor  under the  Guarantee to enforce its rights under the  Guarantee,
without first instituting a legal proceeding against the Partnership or any
other  Person.  The  Preferred  Security  Holders,  by  acceptance  of such
Preferred  Securities,   acknowledge  and  agree  to  the  subordination
provisions and other terms of the Guarantee.

          (c) The proceeds received by the Partnership from the issuance of
Preferred Securities, together with the proceeds of the capital contributed
by the General Partner pursuant to Section 3.1(a) of this Agreement,  shall
be invested  by the  Partnership  in  Subordinated  Debentures  with (i) an
aggregate  principal amount equal to such aggregate  invested  proceeds and
(ii) an interest  rate at least equal to the Dividend rate of the Preferred
Securities.

          (d) The Partnership  may not issue any other limited  partnership
interests in or preferred  securities of the Partnership,  nor may it incur
any indebtedness.  All Preferred  Securities shall rank senior to all other
Interests in the Partnership in respect of the right to receive  Dividends,
Additional   Dividends  or  other  distributions   (including,   without
limitation,  any  distribution  out of the assets of the  Partnership  upon
voluntary  or   involuntary   liquidation,   dissolution,   winding-up   or
termination  of  the  Partnership).   All  Preferred  Securities  redeemed,
purchased or otherwise  acquired by the Partnership shall be canceled.  The
Preferred  Securities will be issued in registered form only.  Dividends on
all Preferred Securities shall be cumulative.

          (e)  Notwithstanding  that  Holders of Preferred  Securities  are
entitled  to vote or  consent as  provided  in this  Agreement,  any of the
Preferred  Securities  that are owned by COMSAT or by any entity owned more
than 50% by COMSAT, or by any entity controlled by COMSAT,  either directly
or  indirectly,  shall not be entitled  to vote or consent  and shall,  for
purposes  of  such  vote  or  consent,  be  treated  as if  they  were  not
outstanding.

          (f) No Holder shall be entitled as a matter of right to subscribe
for or purchase,  or have any preemptive right with respect to, any part of
any new or  additional  limited  partnership  interests,  or of  securities
convertible

                                   -16-

<PAGE>



into  any  Preferred  Securities  or  other  limited  partnership
interests,  whether now or hereafter authorized and whether issued for cash
or other consideration or by way of a Dividend.

                     Section 6.2 Preferred Securities.

          (a) Designation. The Preferred Securities, liquidation preference
$25 per Preferred  Security,  are hereby  designated  as "81/8%  Cumulative
Monthly Income Preferred Securities".

          (b) Dividends.  (i) Preferred  Security Holders shall be entitled
to receive,  when, as and if available  and  determined to be so payable by
the  General  Partner,  except  as  otherwise  provided  below,  cumulative
Dividends at a rate per annum of 81/8% of the stated liquidation preference
of $25 per  Preferred  Security,  calculated on the basis of a 360-day year
consisting of 12 months of 30 days each. For any period shorter than a full
monthly Dividend  period,  Divi- dends will be computed on the basis of the
actual number of days elapsed in such period. Dividends shall be payable in
United States  dollars  monthly in arrears on the last day of each calendar
month of each year,  commencing  July 31, 1995.  Such Dividends will accrue
and be cumulative whether or not they have been declared and whether or not
there are funds of the  Partnership  legally  available  for the payment of
Dividends.  Dividends on the Preferred  Securities  shall be cumulative and
shall accrue from the Closing Date.  Additional Dividends upon any Dividend
arrearages  shall be  declared  and paid in order to  provide,  in  effect,
monthly  compounding  on such  Dividend  arrearages  at a rate of 81/8% per
annum compounded monthly and such Additional Dividends shall accrue. In the
event  that  any date on  which  Dividends  are  payable  on the  Preferred
Securities is not a Business  Day, then payment of the Dividend  payable on
such date will be made on the next  succeeding  day which is a Business Day
(and  without any  interest or other  payment in respect of any such delay)
except that, if such Business Day is in the next succeeding  calendar year,
such payment shall be made on the  immediately  preceding  Business Day, in
each case with the same force and effect as if made on such date.

          (ii)  Dividends  on the  Preferred  Securities  must be  declared
monthly  and be  paid  on the  last  day of  each  calendar  month  (each a
"Dividend  Payment Date") to the extent that the  Partnership  has, on such
date, (x) funds legally available for the payment of such Dividends and (y)
cash on hand sufficient to permit such payments,  it being  understood that
to the extent that funds are not  available  to pay in full all accrued and
unpaid Dividends, the Partnership may pay partial pro rata Dividends to the
extent of funds legally available therefor. Dividends will

                                   -17-

<PAGE>



be payable to the Holders as they appear on the books and records
of the Partnership on the relevant record dates, which will be one Business
Day prior to the relevant Dividend Payment Date. In the event the Preferred
Securities  shall  not  continue  to  remain  in  book-entry-only  form  as
described in Section 10.4 hereof,  the General Partner shall have the right
to select relevant record dates,  which shall be more than one Business Day
prior to the relevant  Dividend  Payment Date. In the event of any extended
interest  payment  period  with  respect  to  the  Subordinated  Debentures
resulting  in the  deferral of the payment of  Dividends  on the  Preferred
Securities,  the Partnership  shall give written notice by first-class mail
to the Holders as to such extended  interest  payment  period no later than
the last  date on which it would  be  required  to  notify  the NYSE of the
record or payment date of the related Dividend on the Preferred Securities.

         (iii)  The Partnership shall not:

          (A) pay, declare or set aside for payment, any dividends or other
distributions on any other Interests in the Partnership; or

          (B) redeem,  purchase or otherwise acquire any other Interests in
the  Partnership;  until, in each case, such time as all accrued and unpaid
Dividends on all of the  Preferred  Securities,  including  any  Additional
Dividends  thereon,  shall have been paid in full for all Dividend  periods
terminating  on or prior to the  date of such  payment  or the date of such
redemption, purchase or acquisition, as the case may be.

          (c)  Redemption.  (i) The Preferred  Securities are redeemable at
the option of the  Partnership,  in whole or in part, from time to time, on
or after July 18,  2000,  at $25 per  Preferred  Security  plus accrued and
unpaid Dividends  (whether or not earned or declared) to the date fixed for
redemption,   including  any  Additional  Dividends  accrued  thereon  (the
"Redemption  Price").  In the event  that  fewer  than all the  outstanding
Preferred Securities are to be so redeemed,  the Preferred Securities to be
redeemed will be selected by lot. If a partial  redemption  would result in
the delisting of the Preferred Securities,  the Partnership may only redeem
the Preferred Securities in whole.

          (ii) If a Tax Event  shall occur and be  continuing,  the General
Partner  shall elect to (a) redeem the  Preferred  Securities in whole (and
not in  part)  at  the  Redemption  Price  within  90  days  following  the
occurrence of such Tax Event; provided that if at the time there is

                                   -18-

<PAGE>



          available to the General  Partner the  opportunity  to eliminate,
within such 90-day period, the Tax Event by taking some ministerial action,
such as filing a form or making an election, or pursuing some other similar
reasonable  measure,  which has no  adverse  effect on the  Partnership  or
COMSAT, the General Partner will pursue such measure in lieu of redemption;
(b) dissolve the  Partnership and cause the  Subordinated  Debentures to be
distributed to the Holders in liquidation of the Partnership;  or (c) cause
the Preferred  Securities to remain outstanding and pay Additional Interest
on the Subordinated Debentures.

          (iii)  If  an  Investment   Company  Event  shall  occur  and  be
continuing,  the  General  Partner  shall  elect to either  (a)  redeem the
Preferred  Securities  in whole (and not in part) at the  Redemption  Price
within 90 days following the occurrence of such  Investment  Company Event;
provided that if at the time there is available to the General  Partner the
opportunity to eliminate, within such 90-day period, the Investment Company
Event by taking some ministerial action, such as filing a form or making an
election,  or pursuing some other similar reasonable measure,  which has no
adverse  effect on the  Partnership  or COMSAT,  the General  Partner  will
pursue such measure in lieu of redemption;  or (b) dissolve the Partnership
and cause the  Subordinated  Debentures to be distributed to the Holders in
liquidation of the Partnership,  within 90 days following the occurrence of
such Investment Company Event.

          (iv)  Upon  the  repayment  of  the  Subordinated  Debentures  at
maturity or upon any  acceleration,  earlier  redemption or otherwise,  the
proceeds  from such  repayment  shall be applied  to redeem  the  Preferred
Securities,  in  whole,  at  the  Redemption  Price.  In  the  case  of any
redemption  pursuant to this clause (iv),  the Preferred  Securities  shall
only be redeemed when repayment of the Subordinated Debentures has actually
been received by the Partnership.

          (v) The Partnership may not redeem fewer than all the outstanding
Preferred Securities unless all accrued and unpaid dividends have been paid
on all Preferred Securities for all monthly dividend periods terminating on
or prior to the date of redemption.

          (d)  Redemption  Procedures.  (i)  Notice  of any  redemption  (a
"Notice of Redemption") of the Preferred Securities to be redeemed pursuant
to Section 6.2(c) will be given by the  Partnership by first-class  mail to
each  record  Holder  not fewer  than 30 nor more than 60 days prior to the
date fixed for redemption  thereof.  For purposes of the calculation of the
date of  redemption  and the dates on which  notices are given  pursuant to
this paragraph (d)(i), a

                                   -19-

<PAGE>



          Notice of Redemption  shall be deemed to be given on the day such
notice is first  mailed  by  first-class  mail,  postage  prepaid,  to each
Holder.  Each Notice of Redemption shall be addressed to each Holder at the
address  of  the  Holder   appearing  in  the  books  and  records  of  the
Partnership.  If all of the Preferred  Securities are  represented by Book-
Entry  Interests,  Notices  of  Redemption  shall  be sent to the  Clearing
Agency.  No defect in the Notice of  Redemption  or in the mailing  thereof
with  respect to any  Preferred  Security  shall affect the validity of the
redemption  proceedings  with  respect  to any  other  Preferred  Security.
Subject  to  the  last  sentence  of  Section  6.2(c)(iv),  any  Notice  of
Redemption shall be irrevocable.

          (ii) If the  Partnership  gives a Notice of Redemption in respect
of  the  Preferred  Securities  and  all of the  Preferred  Securities  are
represented by Book-Entry Interests, then, by 12:00 noon, New York time, on
the redemption  date, the  Partnership  will  irrevocably  deposit with the
Clearing Agency funds sufficient to pay the applicable Redemption Price and
will give the Clearing Agency irrevocable instructions and authority to pay
the Redemption Price to the Holders; if all of the Preferred Securities are
not  represented  by  Book-Entry  Interests,  the  Partnership  may pay the
Redemption Price to a Holder by check upon  presentation by a Holder of the
corresponding  LP  Certificate.  If a Notice of Redemption  shall have been
given and funds deposited as required,  then upon the date of such deposit,
all  rights of the  Preferred  Security  Holders  who hold  such  Preferred
Securities  so called for  redemption  will cease,  except the right of the
Holders of such Preferred  Securities to receive the Redemption  Price, but
without interest on such Redemption Price. In the event that any date fixed
for redemption of Preferred  Securities is not a Business Day, then payment
of the  Redemption  Price  payable  on such  date  will be made on the next
succeeding  day which is a Business  Day (and without any interest or other
payment in respect of any such delay),  except that,  if such  Business Day
falls  in the  next  calendar  year,  such  payment  will  be  made  on the
immediately  preceding  Business  Day.  In the event  that  payment  of the
Redemption Price in respect of Preferred  Securities is improperly withheld
or refused and not paid either by the  Partnership or by COMSAT pursuant to
the  Guarantee,  Dividends  on such  Preferred  Securities  (including  any
Additional   Dividends  thereon)  will  continue  to  accrue  at  the  then
applicable rate, from the original  redemption date to the date of payment,
in which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the Redemption Price.

          (iii)  Subject to the foregoing and  applicable  law  (including,
without  limitation,  United States federal securities laws), COMSAT or its
subsidiaries may at any time

                                   -20-

<PAGE>



          and from time to time purchase  outstanding  Preferred Securities
by tender, in the open market or by private agreement.

          (e)  Liquidation  Rights.  In the  event  of any voluntary  or
involuntary dissolution,  winding-up or termination of the Partnership, the
Holders will have the rights provided in Section 11.4 hereof.

          (f)  Voting  Rights  --  Special  Representative.  (i) If (x) the
Partnership fails to pay Dividends in full on the Preferred  Securities for
18  consecutive  months,  (y)  an  Event  of  Default  (as  defined  in the
Indenture)  occurs and is continuing on the Subordinated  Debentures or (z)
COMSAT is in default on any of its payment or other  obligations  under the
Guarantee,  then  the  Holders,  upon  the  affirmative  vote of at least a
Majority in  Liquidation  Preference of the Preferred  Securities,  will be
entitled to appoint and authorize a Special  Representative  to enforce the
Partnership's rights as a creditor under the Indenture and the Subordinated
Debentures, to enforce the rights of the Holders under the Guarantee and to
enforce  the  rights  of  the  Holders  to  receive  Dividends   (including
Additional   Dividends)   on  the   Preferred   Securities.   The   Special
Representative   shall  not  be  admitted  as  a  general  partner  in  the
Partnership  or  otherwise  be  deemed  to  be a  general  partner  in  the
Partnership  and shall  have no  liability  for the debts,  obligations  or
liabilities of the Partnership.

          (ii) In furtherance of the  foregoing,  and without  limiting the
powers of any Special  Representative so appointed and for the avoidance of
any doubt concerning the powers of the Special Representative,  any Special
Representative,  in its  own  name  and as  Special  Representative  of the
Partnership, may institute a proceeding, including, without limitation, any
suit in  equity,  an  action  at law or other  judicial  or  administrative
proceeding, to enforce the Partnership's rights directly against COMSAT, or
any other  obligor in  connection  with such  obligations  on behalf of the
Partnership, and may prosecute such proceeding to judgment or final decree,
and enforce the same against COMSAT or any other obligor in connection with
such obligations and collect,  out of the property,  wherever situated,  of
COMSAT or any such other obligor upon such obligations, the monies adjudged
or decreed to be payable in the manner provided by law.

          (iii) For purposes of  determining  whether the  Partnership  has
failed to pay Dividends in full for 18 consecutive months,  Dividends shall
be deemed to remain in  arrears,  notwithstanding  any  payments in respect
thereof,  until full cumulative  Dividends have been or contemporaneously
are paid with respect to all monthly Dividend periods

                                   -21-

<PAGE>



terminating  on or  prior  to the date of  payment  of such  full
cumulative Dividends.  Not later than 30 days after such right to appoint a
Special  Representative  arises  and upon not  less  than 15 days'  written
notice by first-class mail to the Holders, the General Partner will convene
a meeting for the purpose of  appointing a Special  Representative.  If the
General  Partner fails to convene such meeting  within such 30-day  period,
the Holders of not less than 10% in Liquidation Preference of the Preferred
Securities  will be entitled to convene  such  meeting.  Except as provided
herein,  the  provisions  of Section  12.3  relating to the  convening  and
conduct of meetings  of the  Partners  will apply with  respect to any such
meeting.  Any Special  Representati-  ve so  appointed  shall cease to be a
Special  Representative  of the Partnership and the Limited Partners if the
Partnership (or COMSAT  pursuant to the Guarantee)  shall have paid in full
all accrued and unpaid  Dividends  (including any Additional  Dividends) on
the  Preferred  Securities  or such default or breach,  as the case may be,
shall have been cured and COMSAT,  in its capacity as the General  Partner,
shall  continue  the  business  of  the  Partnership  without  dissolution.
Notwithstanding the appointment of any such Special Representative,  COMSAT
shall  continue as General  Partner and shall  retain all rights  under the
Indenture,  including the right to extend the interest  payment period from
time to time to a period not exceeding 60 consecutive months.

          (g) Voting  Rights --  Certain  Amendments.  (i) If any  proposed
amendment to this Agreement  provides for, or the General Partner otherwise
proposes to effect, (x) any action which would adversely affect the powers,
preferences or special rights of the Preferred  Securities,  whether by way
of amendment to this Agreement or otherwise (including, without limitation,
the authorization or issuance of any limited  partnership  interests in the
Partnership  other than the Preferred  Securities) or (y) the  dissolution,
winding-up or termination of the Partnership (other than in connection with
the  distribution of  Subordinated  Debentures upon the occurrence of a Tax
Event or Investment  Company Event,  or as described in Section 9.12,  then
the Holders of outstanding Preferred Securities will be entitled to vote on
such  amendment  or proposal of the General  Partner  (but not on any other
amendment  or  proposal)  and  such  amendment  or  proposal  shall  not be
effective  except with the  approval of Holders of not less than 66 2/3% in
Liquidation  Preference of the Preferred  Securities having a right to vote
on the matter;  provided,  however, that no such approval shall be required
if  the  dissolution,  winding-up  or  termination  of the  Partnership  is
proposed or initiated pursuant to Section 11.2 hereof.


                                   -22-

<PAGE>



          (ii) Any required  approval of Holders may be given at a separate
meeting of such Holders  convened for such purpose,  at a meeting of all of
the  Partners  in the  Partnership  or  pursuant  to written  consent.  The
Partnership  will cause written  notice of any meeting at which Holders are
entitled to vote, or of any matter upon which action by written  consent of
such  Holders  is to be taken,  to be mailed  by  first-class  mail to each
Holder of record of Preferred Securities at least 15 days prior to the date
of such meeting or the date by which such action is to be taken.  Each such
notice will include a statement  setting forth (x) the date of such meeting
or the date by which such action is to be taken,  (y) a description  of any
resolution  proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which  written  consent is sought
and (z)  instructions  for the delivery of proxies or consents.  No vote or
consent of the Holders will be required for the  Partnership  to redeem and
cancel Preferred Securities in accordance with this Agreement.

          (iii) Except as provided in this Section 6.2,  Holders shall have
no voting  rights,  and the  Holders  may not remove or replace the General
Partner.

General Partner deems reasonable, keep confidential from the Partners any
information  with respect to the  Partnership  the  disclosure of which the
General  Partner  reasonably  believes is not in the best  interests of the
Partnership or is adverse to the interests of the Partner-

General Partner shall transmit to each Partner a statement  indicating such
Partner's share of each item of Partnership income,  gain, loss,  deduction
or credit for such Fiscal Year for federal income tax purposes.

          Section  7.2  Accounting  Method.  For  both  financial  and  tax
reporting purposes and for purposes of determining  profits and losses, the

accounting  applied  in  a  consistent  manner  and  shall  reflect  all
Partnership   transactions   and  be  appropriate   and  adequate  for  the
Partnership's  business.  The  Partnership's  taxable  year  shall  be  the
calendar year.

         Section 9.5  Exculpation.

          (a)  No  Covered   Person  shall  be  liable,   responsible,   or
accountable  in damages or  otherwise  to the  Partnership  or any  Limited
Partner (in its capacity as such) or any  Affiliate of any Limited  Partner
for any loss,  damages or claim  incurred  by reason of any act or omission
performed or omitted by such Covered  Person in good faith on behalf of the
Partnership and in a manner  reasonably  believed to be within the scope of
the authority conferred on such Covered Person by this Agreement or by law;
provided, however, that a Covered Person shall be liable for any such loss,
damage  or  claim  incurred  by  reason  of such  Covered  Persons's  gross
negligence or willful misconduct with respect to such acts or omissions.

          (b) No  Covered  Person  shall be deemed to have acted with gross
negligence  or willful  misconduct  if such Covered  Person  relied in good
faith  upon the  records  of the  Partnership  and upon  such  information,
opinions,  reports or statements presented to the Partnership by any Person
as to matters the Covered Person reasonably  believes are within such other
Person's  professional or expert  competence and who has been selected with
reasonable care by or on behalf of the Partnership,  including information,
opinions,  reports or  statements as to the value and amount of the assets,
liabilities, profits, losses, or any other facts pertinent to the existence
and amount of assets from which distributions to Partners might properly be

         Section 9.6  Fiduciary Duty.

          (a) To the extent that, at law or in equity, a Covered Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Partnership  or to any  Limited  Partner  (in its  capacity as such) or any
Affiliate  of any  Limited  Partner,  a Covered  Person  acting  under this
Agreement shall not be liable to the Partnership or to any other Person for
its good faith reliance on the provisions

                                   -27-

<PAGE>



of this  Agreement.  The  provisions  of this  Agreement,  to the
extent that they restrict the duties and  liabilities  of a Covered  Person
otherwise existing at law or in equity, are agreed by the parties hereto to
replace such other duties and liabilities of such Covered Person.

          (b) Unless otherwise  expressly  provided herein,  (i) whenever a
conflict of interest  exists or arises  between  Persons,  or (ii) whenever
this  Agreement  or any other  agreement  contemplated  herein  or  therein
provides  that a Covered  Person shall act in a manner that is, or provides
terms that are, fair and reasonable to the Partnership or any Partner,  the
Covered Person shall resolve such conflict of interest,  taking such action
or providing such terms,  considering in each case the relative interest of
each  party  (including  its own  interest)  to such  conflict,  agreement,
transaction  or situation  and the  benefits  and burdens  relating to such
interests, any customary or accepted industry practices, and any applicable
generally accepted  accounting  practices or principles.  In the absence of
bad faith by the Covered Person,  the resolution,  action or terms so made,
taken or provided by the Covered  Person  shall not  constitute a breach of
this Agreement or any other agreement contemplated herein or of any duty or
obligation of the Covered Person at law or in equity or otherwise.

          (c) Whenever in this  Agreement a Covered  Person is permitted or
required  to make a decision  (i) in its  "discretion"  or under a grant of
similar  authority,  the Covered  Person shall be entitled to consider only
such interests and factors as it desires,  including its own interests, and
shall have no duty or obligation to give any  consideration to any interest
of or factors affecting the Partnership or any other Person, or (ii) in its
"good faith" or under another  express  standard,  the Covered Person shall
act under such  express  standard  and shall not be subject to any other or
different standard imposed by this Agreement or other applicable law.

         Section 9.7  [Intentionally Omitted.]

          Section  9.8  Investment  Company  or Tax  Actions.  The  General
Partner is  authorized  and  directed to conduct its affairs and to operate
the Partnership in such a way that the  Partnership  would not be deemed to
be an "invest- ment company"  required to be registered  under the 1940 Act
or taxed as a corporation  for federal  income tax purposes and so that the
Subordinated  Debentures  will be  treated  as  indebtedness  of COMSAT for
federal income tax purposes.  In this  connection,  the General  Partner is
authorized to take any action not  inconsistent  with  applicable  law, the
Certificate  of Limited  Partnership or this  Agreement,  and that does not
materially and adversely affect the interests

or  replacement  does not cause the  Preferred  Securities  (including  any
Successor  Securities)  to  be  downgraded  by  any  nationally  recognized
statistical   rating   organization,   as   that   term  is  used  in  Rule
15c3-1(c)(2)(vi)(F) under the Exchange Act, (v) such merger, consolidation,
amalgamation or replacement does not

Securities)  in any  material  respect  (other  than  with  respect  to any
dilution of the Holders'  interest in the new entity),  (vi) such successor
entity has a purpose  substantially  identical to that of the  Partnership,
(vii)  COMSAT has  provided a  guarantee  to the  holders of the  Successor
Securities with respect to such successor entity having  substantially  the
same  terms  as  the   Guarantee,   and  (viii)   prior  to  such   merger,
consolidation,  amalgamation or replacement, COMSAT has received an opinion
of nationally recognized independent counsel to the Partnership experienced
in such  matters to the effect that (x) such  successor  entity will not be
treated as an association  taxable as a corporation  for federal income tax
purposes,  (y)  following  such  merger,  consolidation,   amalgamation  or
replacement,  neither COMSAT nor such successor  entity will be required to
register as an  investment  company under the 1940 Act and (z) such merger,
consolidation,  amalgamation or replacement  will not adversely  affect the
limited liability of the Holders.

successor as a general partner of the  Partnership  shall be effective upon
the filing of an amendment to the  Certificate  with the Secretary of State
of the State of  Delaware  which  indicates  that such  successor  has been
admitted as a general  partner in the  Partnership.  If the General Partner

Indenture,  the  General  Partner  shall be deemed  to have  ceased to be a
general partner in the Partnership simultaneously with the admission of the
successor  as a general  partner  in the  Partnership  and such  successors
assumption hereof. Any such successor general partner in the Partnership is
hereby  authorized  to and shall  continue the business of the  Partnership

the name of the designated transferee or transferees.  Every LP Certificate
surrendered for  registration of transfer shall be accompanied by a written
instrument  of transfer in form  satisfactory  to the General  Partner duly
executed  by the  Preferred  Security  Holder or his or her  attorney  duly
authorized in writing. Each LP Certificate  surrendered for registration of
transfer  shall be canceled by the General  Partner.  A transferee of an LP

other  communication  to the Preferred  Security  Holders is required under
this Agreement, unless and until Definitive LP Certificates shall have been
issued to the  Preferred  Security  Owners  pursuant to Section  10.7,  the
General  Partner shall give all such notices and  communications  specified
herein  to be given  to the  Preferred  Security  Holders  to the  Clearing
Agency, and shall have no obligations to the Preferred Security Owners.

          Section 10.6  Appointment of Successor  Clearing  Agency.  If any
Clearing Agency elects to discontinue its services as securities depository
with respect to the Preferred  Securities,  the General Partner may, in its
sole  discretion,  appoint a successor  Clearing Agency with respect to the
Preferred Securities.

          Section 10.7  Definitive LP  Certificates;  Appointment of Paying
Agent.  If (a) the Clearing  Agency elects to  discontinue  its services as
securities depository and no successor  clearinghouse is obtained within 90
days  after  such  discontinuance  pursuant  to  Section  10.6  or (b)  the
Partnership  elects to terminate the book-entry system through the Clearing

circumstances,  the  General  Partner  will  appoint a paying  agent to pay
Dividends,  redemption  payments or  liquidation  payments on behalf of the

global  LP  Certificate  or LP  Certificates  representing  the  Book-Entry
Interests by the Clearing Agency, accompanied by registration instructions,
the General Partner shall cause  Definitive LP Certificates to be delivered
to Preferred  Security  Owners in accordance  with the  instructions of the
Clearing Agency.  Neither the General Partner nor the Partnership  shall be
liable for any delay in delivery of such  instructions and may conclusively
rely on, and shall be  protected  in relying  on,  such  instructions.  Any
Person  receiving a  Definitive  LP  Certificate  in  accordance  with this
Article X shall be admitted to the  Partnership  as a Limited  Partner upon
receipt of such  Definitive LP Certifi- cate and shall be registered on the
books and records of the Partnership as a Preferred  Security  Holder.  The
Clearing Agency or the nominee of the Clearing Agency,  as the case may be,
shall cease to be a Limited  Partner  under this  Section  10.7 at the time
that at least one  additional  Person is admitted to the  Partnership  as a
Limited  Partner in accordance  with this Section 10.7.  The  Definitive LP

notice of dishonor, notice of redemption and all other notices and demands.

     2.3 Obligations Not Affected. The obligations,  covenants,  agreements
and duties of COMSAT  under this  Guarantee  shall in no way be affected or
impaired  by  reason  of the  happening  from  time  to  time of any of the
following:

     (a) the release or waiver,  by operation of law or  otherwise,  of the
performance  or  observance  by COMSAT  Capital  of any  express or implied
agreement, covenant, term or condition relating to the Preferred

Page 3
<PAGE>



     Securities to be performed or observed by COMSAT Capital;

     (b) the extension of time for the payment by COMSAT  Capital of all or
any  portion  of  the  Dividends  (including  any  Additional   Dividends),
Redemption Price,  Liquidation Distribution or any other sums payable under
the terms of the  Preferred  Securities  or the  extension  of time for the
performance of any other obligation under, arising out of, or in connection
with, the Preferred Securities;

     (c) any failure,  omission,  delay or lack of diligence on the part of
the Holders or the Special  Representative  to enforce,  assert or exercise
any right,  privilege,  power or remedy  conferred  on such Holders or such
Special Representative pursuant to the terms of the Preferred Securities or
the  Limited  Partnership  Agreement,  or any  action  on the  part  of the
Holders,   the  Special   Representative  or  COMSAT  Capital  granting  or
consenting to indulgence or extension of any kind;

     (d) the voluntary or involuntary liquidation, dissolution, winding-up,
sale of any collateral,  receivership,  insolvency,  bankruptcy, assignment
for the benefit of creditors,  reorganization,  arrangement, composition or
readjustment  of debt of, or other similar  proceedings  affecting,  COMSAT
Capital or any of the assets of COMSAT Capital;

     (e)  any  invalidity  of,  or  defect  or  deficiency  in,  any of the
Preferred Securities; or 

     (f) the settlement or compromise of any obligation guaranteed hereby or 
hereby incurred.

There  shall be no  obligation  of the Holders to give notice to, or obtain
any  consent  of,  COMSAT  with  respect  to  the  happening  of any of the
foregoing.

     2.4 Guarantor,  Special Representative or Holders May Proceed Directly
Against  COMSAT.  This  Guarantee  is a  guarantee  of  payment  and not of
collection. This Guarantee will be deposited with the General Partner to be
held for the benefit of the Holders.  In the event of an  appointment  of a
Special  Representative  pursuant to the Limited Partnership  Agreement to,
among other things, enforce the rights of the Holders under this Guarantee,
the Special  Representative  may take possession of this Guarantee for such
purpose.  If no Special  Representative  has been appointed to enforce this
Guarantee,  the General  Partner has the right to enforce this Guarantee on
behalf of the Holders.

Page 4
<PAGE>



The  Holders  of  not  less  than  10%  in  liquidation  preference  of all
outstanding  Preferred Securities have the right to direct the time, method
and place of conducting any proceeding for any remedy  available in respect
of this  Guarantee,  including  the  giving of  directions  to the  General
Partner or the Special  Representative,  as the case may be. If the General
Partner or the Special  Representative  fails to enforce this  Guarantee as
provided  above,  any Holder may enforce this  Guarantee  directly  against
COMSAT as guarantor,  and COMSAT waives any right or remedy to require that
any action be brought  against COMSAT Capital or any other person or entity
before  proceeding  against  COMSAT.  Subject to Section  2.5  hereof,  all
waivers  herein  contained  shall be  without  prejudice  to the right of a
Holder or the Special  Representative,  at its option,  to proceed  against
COMSAT  Capital,  whether by separate  action or by joinder.  COMSAT agrees
that this  Guarantee  shall not be  discharged  except  by  payment  of the
Guarantee  Payments  in full (to the extent not  previously  paid by COMSAT
Capital,  but subject to the proviso in Section 2.7 hereof) and by complete
performance of all obligations under this Guarantee.

     2.5 Subrogation.  COMSAT shall be subrogated to all (if any) rights of
the Holders  against  COMSAT  Capital in respect of any amounts paid to the
Holders by COMSAT  under this  Guarantee  and shall have the right to waive
payment of any amount of  Dividends  in respect of which  payment  has been
made to the Holders by COMSAT  pursuant  to Section  2.1 hereof;  provided,
however,  that COMSAT shall not (except to the extent required by mandatory
provisions  of law)  exercise  any  rights  which it may  acquire by way of
subrogation  or any indemnity,  reimbursement  or other  agreement,  in all
cases as a result of a payment under this Guarantee, if, at the time of any
such payment,  any amounts are due and unpaid under this Guarantee.  If any
amount  shall be paid to COMSAT in  violation  of the  preceding  sentence,
COMSAT  agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

     2.6 Independent Obligations.  COMSAT acknowledges that its obligations
hereunder are independent of the obligations of COMSAT Capital with respect
to the  Preferred  Securities  and that COMSAT shall be liable as principal
and sole debtor under this Guarantee to make Guarantee Payments pursuant to
the terms of this  Guarantee  notwithstanding  the  occurrence of any event
referred to in  subsections  (a)  through  (f),  inclusive,  of Section 2.3
hereof.

     2.7 Termination.  This Guarantee shall terminate as to each Holder and
be of no further force and effect upon full payment of the Redemption Price
of all  Preferred  Securities  held  by  such  Holder  and  will  terminate
completely  upon full payment of the amounts  payable upon  liquidation  of
COMSAT Capital; provided, however, that this Guarantee shall continue to be
effective or

Page 5
<PAGE>



shall be  reinstated,  as the case may be, if at any time any  Holder  must
restore  payment of any sums paid under the  Preferred  Securities or under
this Guarantee for any reason whatsoever.


3.   Certain Covenants of COMSAT.

     3.1 Dividends and Other Payments.  So long as any Preferred Securities
remain  outstanding,  COMSAT  will not declare or pay any  dividend  on, or
redeem,  purchase,  acquire or make a liquidation  payment with respect to,
any of its capital stock (other than as a result of a  reclassification  of
capital  stock or the  exchange  or  conversion  of one  class or series of
capital  stock for  another  class or series of capital  stock) or make any
guarantee  payments  with  respect  to the  foregoing,  if at such time (a)
COMSAT  has  exercised  its  option  to  defer  interest  payments  on  the
Subordinated  Debentures and such deferral is continuing,  (b) COMSAT shall
be in default with respect to its payment or other  obligations  hereunder,
or (c) there shall have occurred any event that,  with the giving of notice
or the lapse of time or both,  would  constitute  an Event of Default under
the Indenture.

     3.2 Certain Other  Covenants.  COMSAT  covenants  that, so long as any
Preferred Securities remain outstanding, it shall: (a) maintain direct 100%
ownership of the  Partnership  Interests and any other  interests in COMSAT
Capital  other than the  Preferred  Securities  (except as permitted in the
Limited Partnership Agreement); (b) cause at least 3% of the total value of
COMSAT  Capital  and at least 3% of all  interest in the  capital,  income,
gain, loss,  deduction and credit of COMSAT Capital to be held by COMSAT as
General Partner; (c) not voluntarily dissolve,  wind up or liquidate itself
or COMSAT  Capital;  (d) remain the General  Partner of COMSAT  Capital and
timely perform all of its duties as General Partner  (including the duty to
cause  COMSAT  Capital  to  declare  and  pay  dividends  on the  Preferred
Securities),  unless a permitted  successor  General  Partner is  appointed
pursuant to the Limited Partnership Agreement; and (e) subject to the terms
of the Preferred Securities, use reasonable efforts to cause COMSAT Capital
to remain a Delaware limited  partnership and otherwise  continue not to be
treated as an  association  taxable  as a  corporation  for  United  States
federal  income tax purposes,  except,  in all cases,  in  connection  with
certain mergers,  consolidations or amalgamations  permitted by the Limited
Partnership Agreement.

4.   Subordination.

     4.1 Subordination. COMSAT covenants and agrees, and each Holder by his
or  her  acceptance  of  such  Preferred  Securities  shall  be  deemed  to
acknowledge  and agree that for all  purposes  (including  any  bankruptcy,
insolvency, or reorganization of

Page 6
<PAGE>



COMSAT)  this  Guarantee  constitutes  an  unsecured  obligation  of COMSAT
ranking (i)  subordinate  and junior in right of payment to all liabilities
of COMSAT,  (ii) pari passu with the most senior  preferred  or  preference
stock  now or  hereafter  issued by COMSAT  and with any  guarantee  now or
hereafter  entered into by COMSAT in respect of any preferred or preference
stock or preferred  securities  of any affiliate of COMSAT and (iii) senior
to COMSAT Common Stock.


5.   Miscellaneous.

     5.1 Third Party  Beneficiaries.  Subject to the limitations of Section
2.4, all of COMSAT's  obligations  under this  Guarantee  shall be directly
enforceable  by the Holders from time to time of the Preferred  Securities.
Each Holder is an intended third-party beneficiary of this Guarantee.

     5.2 Successors and Assigns. All guarantees and agreements contained in
this Guarantee shall bind the successors,  assigns, receivers, trustees and
representatives  of COMSAT and shall  inure to the  benefit of the  Holders
then outstanding.  Except as permitted by Section 5.4 hereof,  COMSAT shall
not assign its rights or delegate  its  obligations  hereunder  without the
prior  approval  of the Holders of not less than  66-2/3% of the  aggregate
liquidation preference of the Preferred Securities then outstanding.

     5.3  Amendments.  Except  with  respect  to any  changes  which do not
adversely  affect  the  rights of  Holders  (in which  case no vote will be
required),  this  Guarantee may only be amended with the prior  approval of
the  Holders  of  not  less  than  66-2/3%  of  the  aggregate  liquidation
preference of the Preferred  Securities  then  outstanding,  which approval
shall be obtained as described in the Limited Partnership Agreement.

     5.4  Consolidation,  Merger or Sale of  Assets.  COMSAT,  without  the
consent  of any  Holders,  may merge or  consolidate  with or into  another
entity or may permit another  entity to merge or  consolidate  with or into
COMSAT,  and may  sell,  transfer  or  lease  all or  substantially  all of
COMSAT's assets to another entity,  if (a) at such time no Event of Default
(as defined in the  Indenture)  shall have occurred and be  continuing,  or
would occur as a result of such merger,  consolidation or sale, transfer or
lease and (b) the  survivor  of such merger or  consolidation  or entity to
which COMSAT assets are sold,  transferred or leased is an entity organized
under the laws of the United States or any state thereof or the District of
Columbia,  becomes  the  General  Partner  (if  COMSAT is then the  General
Partner),  assumes all of COMSAT's obligations under this Guarantee and has
a net worth  equal to at least 10% of the total  capital  contributions  to
COMSAT Capital.

Preferred Securities.

or delivered to the Trustee for cancellation;

in trust by the Company (if the Company  shall act as its own Paying  Agent
(as defined herein)) for the Holders of such Securities; provided, that, if

Trustee proof  satisfactory  to it that such  Securities are held by a bona
fide purchaser in whose hands such Securities are valid  obligations of the
Company;

provided, however, that in determining whether the Holders of the requisite
principal  amount of the  Outstanding  Securities  have given any  request,
demand,  authorization,  direction,  notice,  consent or waiver  hereunder,

any  Affiliate of the Company or of such other  obligor  (other than COMSAT
Capital)  shall be  disregarded  and deemed not to be  Outstanding,  except
that, in determining whether the Trustee shall be protected in relying upon
any such request,  demand,  authorization,  direction,  notice,  consent or
waiver,  only Securities which the Trustee knows to be so owned shall be so
disregarded.  Securities so owned which have been pledged in good faith may
be regarded as Outstanding if the pledgee  establishes to the  satisfaction
of  the  Trustee  the  pledgee's  right  so to act  with  respect  to  such
Securities  and that the  pledgee is not the  Company or any other  obligor
upon the  Securities  or any  Affiliate  of the  Company  or of such  other
obligor.

Section 103.  Form of Documents Delivered to Trustee.

                  In any case where  several  matters  are  required  to be
certified by, or covered by an opinion of, any specified  Person, it is not
necessary  that all such matters be certified by, or covered by the opinion
of, only one such  Person,  or that they be so certified or covered by only
one  document,  but one such  Person may  certify  or give an opinion  with
respect to some  matters  and one or more  other  such  Persons as to other
matters,  and any such  Person  may  certify  or give an opinion as to such
matters in one or several documents.

                  Any  certificate  or opinion of an officer of the Company
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations  by, counsel,  unless such officer knows, or
in the exercise of reasonable  care should know,  that the  certificate  or
opinion  or  representations  with  respect to the  matters  upon which his
certificate  or opinion is based are  erroneous.  Any such  certificate  or
opinion of counsel may be based,  insofar as it relates to factual matters,
upon a  certificate  or opinion  of, or  representations  by, an officer or
officers of the Company stating that the  information  with respect to such
factual  matters is in the  possession of the Company,  unless such counsel
knows,  or in the  exercise  of  reasonable  care  should  know,  that  the
certificate or opinion or representations  with respect to such matters are
erroneous.

                  Where any Person is required to make, give or execute two
or  more  applications,   requests,  consents,  certificates,   statements,
opinions or other instruments under this Indenture, they may, but need not,
be consolidated and form one instrument.


Section 104.      Acts of Holders; Record Dates.

                  (a)  Any  request,  demand,   authorization,   direction,
notice,  consent,  waiver or other action  provided by this Indenture to be
given or taken by Holders may be embodied in and  evidenced  by one or more
instruments of substantially similar tenor signed by such Holders in person
or by agent duly  appointed  in writing;  and,  except as herein  otherwise
expressly provided, such action shall become effective when such instrument
or  instruments  are  delivered  to the  Trustee  and,  where it is  hereby
expressly required, to the Company. Such instrument or instruments (and the
action  embodied  therein  and  evidenced  thereby)  are  herein  sometimes
referred  to as the  "Act"  of  the  Holders  signing  such  instrument  or
instruments.  Proof of  execution  of any such  instrument  or of a writing
appointing  any such  agent  shall be  sufficient  for any  purpose of this
Indenture  and (subject to Section 601)  conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section.

                  (b)        The fact and date of the execution by any Person
of any such instrument or writing may be proved by the affidavit


                                       10


<PAGE>



of a witness of such  execution or by a  certificate  of a notary public or
other  officer  authorized  by  law  to  take   acknowledgments  of  deeds,
certifying   that  the  individual   signing  such  instrument  or  writing
acknowledged  to him the execution  thereof.  Where such  execution is by a
signer  acting in a  capacity  other  than his  individual  capacity,  such
certificate  or affidavit  shall also  constitute  sufficient  proof of his
authority.  The fact and date of the  execution of any such  instrument  or
writing,  or the authority of the Person  executing  the same,  may also be
proved in any other manner which the Trustee deems sufficient.

                  (c) The Company  may, in the  circumstances  permitted by
the Trust  Indenture Act, fix any day as the record date for the purpose of
determining  the  Holders  entitled  to give or take any  request,  demand,
authorization,  direction,  notice,  consent, waiver or other action, or to
vote on any  action,  authorized  or  permitted  to be  given  or  taken by
Holders.  If not set by the Company  prior to the first  solicitation  of a
Holder made by any Person in respect of any such action, or, in the case of
any such vote,  prior to such vote,  the record date for any such action or
vote shall be the 30th day (or, if later,  the date of the most recent list
of Holders  required to be provided  pursuant to Section 701) prior to such
first  solicitation  or vote, as the case may be. With regard to any record
date,  only the  Holders  on such date (or their duly  designated  proxies)
shall be entitled to give or take, or vote on, the relevant action.

                  (d)        The ownership of Securities shall be proved by
the Security Register.

                  (e)  Any  request,  demand,   authorization,   direction,
notice,  consent,  waiver or other Act of the Holder of any Security  shall
bind  every  future  Holder of the same  Security  and the  Holder of every
Security issued upon the  registration  of transfer  thereof or in exchange
therefor  or in lieu  thereof  in  respect  of  anything  done,  omitted or
suffered  to be done by the  Trustee or the  Company in  reliance  thereon,
whether or not notation of such action is made upon such Security.


Section 105.      Notices, etc., to Trustee, Company and COMSAT
                  Capital.

                  Any request, demand,  authorization,  direction,  notice,
consent,  waiver or Act of Holders or other document  provided or permitted
by this Indenture to be made upon, given or furnished to, or filed with,

                  (1)        the Trustee by any Holder or by the Company shall
be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at its
Corporate Trust Office, Attention: Corporate Trust Services
Division, or



                                       11


<PAGE>



                  (2) the Company by the Trustee or by any Holder  shall be
sufficient for every purpose  hereunder  (unless otherwise herein expressly
provided) if in writing and mailed,  first-class  postage  prepaid,  to the
Company addressed to it at the address of its principal office specified in
the first paragraph of this  instrument or at any other address  previously
furnished in writing to the Trustee by the Company.


Section 106.      Notice to Holders; Waiver.

                  Where this  Indenture  provides  for notice to Holders of
any event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed,  first-class postage prepaid,
to each Holder as to which such  notice is  required to be made,  at his or
her  address  as it appears in the  Security  Register,  not later than the
latest date (if any),  and not  earlier  than the  earliest  date (if any),
prescribed  for the  giving of such  notice.  In any case  where  notice to
Holders is given by mail,  neither the failure to mail such notice, nor any
defect in any notice so mailed,  to any particular  Holder shall affect the
sufficiency  of such  notice  with  respect  to other  Holders.  Where this
Indenture  provides for notice in any manner,  such notice may be waived in
writing by the Person  entitled to receive  such notice,  either  before or
after the event,  and such waiver shall be the  equivalent  of such notice.
Waivers of notice by  Holders  shall be filed  with the  Trustee,  but such
filing  shall not be a condition  precedent  to the  validity of any action
taken in reliance upon such waiver.

                  In case by  reason  of the  suspension  of  regular  mail
service or by reason of any other cause it shall be  impracticable  to give
such  notice  by mail,  then  such  notification  as shall be made with the
approval of the Trustee  shall  constitute  a sufficient  notification  for
every purpose hereunder.


Section 107.      Immunity of Shareholders, Officers and Directors.

                  No recourse shall be had for the payment of the principal
of or the  interest,  if any,  on,  any  Security,  or for any claim  based
thereon, or upon any obligation, covenant or agreement of this Indenture or
any supplemental indenture,  against any shareholder,  officer or director,
as such,  past,  present  or  future  of the  Company  or of any  successor
corporation,  either  directly  or  indirectly  through  the Company or any
successor  corporation,  whether by virtue of any constitution,  statute or
rule  of  law  or by  the  enforcement  of any  assessment  or  penalty  or
otherwise; it being expressly agreed and understood that this Indenture and
any  supplemental  indenture and all the  Securities  are solely  corporate
obligations, and that no personal liability whatever shall attach to, or is
incurred by, any shareholder, officer or director, past, present or future,
of the Company or of any successor corporation, either directly or


                                       12


<PAGE>



indirectly through the Company or any successor corporation, because of the
incurring of the  indebtedness  hereby  authorized or under or by reason of
any of the obligations, covenants or agreements contained in this Indenture
or in any of the Securities,  or to be implied  herefrom or therefrom;  and
that any and all such personal  liability is hereby expressly  released and
waived  as a  condition  of,  and as part  of the  consideration  for,  the
execution of this Indenture,  any  supplemental  indenture and the issue of
the Securities.

Section 108.      Conflict with Trust Indenture Act.

                  If any provision  hereof  limits,  qualifies or conflicts
with a provision  of the Trust  Indenture  Act that is required  under such
Trust Indenture Act to be a part of and govern this  Indenture,  the latter
provision  shall control.  If any provision of this  Indenture  modifies or
excludes any  provision of the Trust  Indenture Act that may be so modified
or  excluded,  the  latter  provision  shall  be  deemed  to  apply to this
Indenture as so modified or to be excluded, as the case may be.


Section 109.      Effect of Headings and Table of Contents.

                  The Article and Section  headings herein and the Table of
Contents  are for  convenience  only and shall not affect the  construction
hereof.


Section 110.      Successors and Assigns.

                  All  covenants and  agreements  in this  Indenture by the
Company  shall bind their  respective  successors  and assigns,  whether so
expressed or not.


Section 111.      Separability Clause.

                  In  case  any  provision  in  this  Indenture  or in  the
Securities  shall be  invalid,  illegal  or  unenforceable,  the  validity,
legality and  enforceability  of the remaining  provisions shall not in any
way be affected or impaired thereby.

Section 112.      Benefits of Indenture.

                  The Company's  obligations  under this  Indenture and the
Securities will also be for the benefit of the holders from time to time of
the Preferred  Securities.  Nothing in this Indenture or in the Securities,
express or implied, shall give to any Person, other than the parties hereto

compound  monthly  and will  accrue  at the rate of 81/8%  per annum on any
interest  installment  that is not paid at the end of any monthly  interest
period or when otherwise due. The amount of interest payable for any period
will be computed on the basis of twelve  30-day  months and a 360-day  year
and, for any period shorter than a full monthly  interest  period,  will be
computed on the basis of the actual  number of days elapsed in such period.
In the event that any date on which interest is payable on this Security is
not a Business  Day,  then a payment of the  interest  payable on such date
will be made on the  next  succeeding  day  which  is a  Business  Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next  succeeding  calendar year,  such
payment shall be made on the  immediately  preceding  Business Day, in each
case with the same force and effect as if


                                       15


<PAGE>



made on such date. A "Business  Day" shall mean any day other than a day on
which banking  institutions  in New York City are authorized or required by
law or executive  order to close.  The interest so payable,  and punctually
paid or duly provided  for, on any Interest  Payment Date will, as provided
in the Indenture, be paid to the Person in whose name this Security (or one
or more  Predecessor  Securities) is registered at the close of business on
the Regular Record Date for such interest,  which shall be the Business Day
next preceding such Interest Payment Date; provided,  however, that if this
Security shall not continue to remain in book-entry-only  form, the Company
shall have the right to select  record  dates  which shall be more than one
Business Day prior to the Interest  Payment Date.  Any such interest not so
punctually  paid or duly provided for will forthwith cease to be payable to
the Holder on such Regular Record Date and may either be paid to the Person
in whose name this  Security  (or one or more  Predecessor  Securities)  is
registered  at the  close of  business  on a  Special  Record  Date for the
payment  of such  Defaulted  Interest  to be fixed by the  Trustee,  notice
whereof shall be given to Holders of Securities not less than 10 days prior
to such  Special  Record  Date,  or be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

                  The Company may, by Company Order, prior to the Scheduled
Maturity Date,  extend the maturity date of the Securities no more than one
time,  for up to an additional 19 years from the Scheduled  Maturity  Date,
provided  that at the time of such  extension  (i) no Event of  Default  or
event which after notice or lapse of time,  or both,  would become an Event
of  Default  specified  in  Section  501(5) or  Section  501(6)  shall have
occurred and be  continuing;  (ii) the Company has made timely  payments of
interest  (including  Additional  Interest)  on the  Securities  during the
immediately preceding 18 months without deferrals;  (iii) COMSAT Capital is
not in arrears on payments of  distributions  on the Preferred  Securities;
(iv) the Securities shall continue to pay Interest at least at a rate equal
to the rate of distributions that accrue on the Preferred  Securities;  (v)
the Securities are rated  Investment  Grade; and (vi) the final maturity of
the  Securities  is not  later  than  the 49th  anniversary  of the date of
issuance of the Preferred Securities.

                  COMSAT  shall have the right at any time  during the term
of this Security to extend the interest payment period from time to time to
a period not exceeding 60 consecutive months, during which periods interest
will compound monthly, and at the end of which periods COMSAT shall pay all
interest  then  accrued and unpaid  (together  with  Additional  Interest);
provided that during any such extended interest payment period COMSAT shall
not declare or pay any dividend on, or redeem, purchase,  acquire or make a
liquidation  payment with respect to, any of its capital  stock (other than
as a result of a reclassification of such


                                       16


<PAGE>



capital  stock or the  exchange  or  conversion  of one  class or series of
capital  stock for another class or series of capital  stock),  or make any
guarantee payments with respect to the foregoing (other than payments under
the  Parent  Guarantee).  Prior to the  termination  of any  such  extended
interest  payment  period,  COMSAT may further extend the interest  payment
period,  provided that such extended  interest payment period together with
all  such  previous  and  further  extensions  thereof  may not  exceed  60
consecutive  months,  nor may such extended  interest payment period extend
the Stated Maturity of this Security. After COMSAT has paid all accrued and
unpaid  interest  (including  Additional  Interest)  following  an extended
interest  payment period,  it may again extend interest payment periods for
up to 60 consecutive months,  subject to the preceding sentence.  If COMSAT
Capital  shall be the sole  Holder of the  Securities,  COMSAT  shall  give
COMSAT  Capital  notice of its  selection of an extended  interest  payment
period one Business Day prior to the earlier of (i) the date the  dividends
on the Preferred  Securities are payable or (ii) the date COMSAT Capital is
required  to give  notice to the NYSE or other  applicable  self-regulatory
organization  or to holders of the Preferred  Securities of the record date
or the date such  dividend is  payable,  but in any event not less than one
Business Day prior to such record date.  COMSAT shall cause COMSAT  Capital
to give notice of COMSAT's  selection  of such  extended  interest  payment
period to the holders of the Preferred Securities. If COMSAT Capital is not
the sole  Holder of the  Securities,  COMSAT  shall give the Holders of the
Securities  notice of its  selection of such an extended  interest  payment
period ten Business  Days prior to the earlier of (i) the Interest  Payment
Date or (ii) the date  COMSAT  is  required  to give  notice to the NYSE or
other  applicable  self-regulatory  organization,  or to the Holders of the
Securities, of the record or payment date of such related interest payment,
but in any event not less than two Business Days prior to such record date.

                  Payment of the principal of and interest on this Security
issued as a global  security will be made to DTC, as the depository for the
Securities,  in such coin or currency of the United States of America as at
the time of payment  is legal  tender  for  payment  of public and  private
debts.  If the Securities are issued in  certificated  form,  principal and
interest  will  be  payable,   the  transfer  of  the  Securities  will  be
registrable and the Securities will be exchangeable for Securities of other
denominations  of a like aggregate  principal amount at the corporate trust
office of the Trustee in New York City; provided, however, that, unless the
Securities  are held by COMSAT Capital or any successor  permissible  under
the Limited  Partnership  Agreement (in which case payment shall be made by
wire transfer),  payment of interest may, at the option of COMSAT,  be made
by check  mailed to the  address of the  Persons  entitled  thereto as such
address shall appear in the Security Register.

                  Reference is hereby made to the further provisions of
the Indenture summarized on the reverse hereof, which further


                                       17

provisions shall for all purposes have the same effect as if set
forth at this place.

                  Unless the certificate of authentication  hereon has been
executed  by the  Trustee  referred  to on the  reverse  hereof  by  manual
signature,  this  Security  shall not be entitled to any benefit  under the
Indenture or be valid or obligatory for any purpose.

                  IN WITNESS WHEREOF,  COMSAT has caused this instrument to
be duly executed under its corporate seal.

Attest:


Section 203.      Form of Reverse of Security.

                  This  Security  is  one  of a duly  authorized  issue  of
Securities  of  COMSAT,   designated  as  its  81/8%  Junior   Subordinated
Deferrable Interest Debentures Due July 18, 2025 (subject to extension,  as
provided  herein)  (herein called the  "Securities"),  limited in aggregate
principal  amount  to  $206,200,000,  issued  and  to be  issued  under  an
Indenture,  dated as of July 18,  1995  (herein  called  the  "Indenture"),
between COMSAT and The First National Bank of Chicago,  as Trustee  (herein
called the "Trustee",  which term includes any successor  trustee under the
Indenture),  to which  Indenture and all  indentures  supplemental  thereto
reference  is  hereby  made  for a  statement  of  the  respective  rights,
limitations  of rights,  duties and  immunities  thereunder of COMSAT,  the
Trustee, the Holders of the Securities, the holders of Preferred Securities
and the  holders  of Senior  Indebtedness  and of the terms  upon which the
Securities are, and are to be, authenticated and delivered.  All terms used
in this  Security  which are  defined in the  Indenture  or in the  Limited
Partnership  Agreement  attached as Annex A thereto shall have the meanings
assigned to them in the Indenture or the Limited Partnership Agreement,  as
the case may be.

     The indebtedness evidenced by this Security is, to the extent provided 
in the Indenture, subordinate and subject in right of payment to the prior 
payment in full of all Senior Indebtedness, and this Security is issued 
subject to the provisions of the Indenture with respect thereto. Each Holder 
of

                                       18

<PAGE>



this  Security,  by accepting the same, (a) agrees to and shall be bound by
such  provisions,  (b)  authorizes and directs the Trustee on his behalf to
take such action as may be  necessary  or  appropriate  to  effectuate  the
subordination so provided and (c) appoints the Trustee his attorney-in-fact
for any and all such purposes.

                  The  Trustee  or the  Holders  of not  less  than  25% in
aggregate  outstanding  principal  amount of the Securities may declare the
principal  of and  interest  (including  any  Additional  Interest)  on the
Securities  due and payable  immediately  on default  with  respect to such
Securities;  provided, however, that after such acceleration,  but before a
judgment  or decree  based on  acceleration,  the  Holders of a majority in
aggregate  principal  amount of outstanding  Securities  may, under certain
circumstances, rescind and annul such acceleration if all Events of Default
with respect to such Securities,  other than the non-payment of accelerated
principal, have been cured or waived as provided in the Indenture.

                  The Indenture permits, with certain exceptions as therein
provided,  COMSAT and the  Trustee,  with the consent of the Holders of not
less than a majority in principal  amount of the Securities,  to modify the
Indenture or any  supplemental  indenture  affecting the  Securities or the
rights of the Holders of Securities. Any such consent by the Holder of this
Security  shall be  conclusive  and  binding  upon such Holder and upon all
future  Holders  of this  Security  and of any  Security  issued  upon  the
registration of transfer  hereof or in exchange  herefor or in lieu hereof,
whether or not notation of such consent is made upon this Security.

                  The  Securities  shall be  subject to  redemption  at the
option  of  COMSAT  without  premium  or  penalty,  in  whole  or in  part,
concurrent   with  the  redemption  by  COMSAT  Capital  of  the  Preferred
Securities (if any Preferred Securities are then outstanding),  at any time
or from  time to time  on or  after  July  18,  2000,  as  provided  in the
Indenture,  upon not less than 30 days' nor more than 60 days' notice, at a
Redemption Price equal to 100% of the principal amount to be redeemed, plus
any accrued and unpaid interest (including Additional Interest, if any), to
the Redemption Date, but interest  installments whose Stated Maturity is on
or prior to such  Redemption  Date will be payable  to the  Holders of such
Securities of record at the close of business on the relevant  Record Dates
referred  to on the face  hereof,  all as provided  in the  Indenture.  The
Company has  covenanted to exercise such right to redeem if COMSAT  Capital
redeems its Preferred Securities.

                  No reference  herein to the Indenture and no provision of
this Security or of the Indenture  shall alter or impair the  obligation of
COMSAT,  which is absolute and  unconditional,  to pay the principal of and
interest on this Security at the times,  place and rate, and in the coin or
currency, herein prescribed.

                  As  provided  in the  Indenture  and  subject  to certain
limitations therein set forth, the transfer of this Security is registrable
in the Security Register,  upon surrender of this Security for registration
of transfer at the corporate  trust office of the Trustee in New York City,
duly  endorsed by, or  accompanied  by a written  instrument of transfer in
form satisfactory to COMSAT and the Security Registrar duly executed by the
Holder  hereof or his or her  attorney  duly  authorized  in  writing,  and
thereupon one or more new Securities,  of authorized  denominations and for
the same  aggregate  principal  amount,  will be issued  to the  designated
transferee or transferees.

                  The  Securities,  if  distributed to holders of Preferred
Securities in a dissolution of COMSAT Capital,  will initially be issued as
a global security.  If the Securities are issued in certificated form, such
Securities will be issued in  denominations  of $25 and integral  multiples
thereof.  As provided in the Indenture  and subject to certain  limitations
therein  set  forth,  Securities  are  exchangeable  for a  like  aggregate
principal amount of Securities of a different authorized  denomination,  as
requested by the Holder surrendering the same.

                  No service charge shall be made for any such registration
of transfer or exchange, but COMSAT may require payment of a sum sufficient
to  cover  any tax or  other  governmental  charge  payable  in  connection
therewith.

                  Prior   to  due   presentment   of  this   Security   for
registration  of transfer,  COMSAT,  the Trustee and any agent of COMSAT or
the Trustee may treat the Person in whose name this  Security is registered
as the owner  hereof  for all  purposes,  whether or not this  Security  be
overdue,  and  neither  COMSAT,  the  Trustee  nor any such agent  shall be
affected by notice to the contrary.

                  The Indenture  contains  provisions for defeasance at any
time of the entire  indebtedness of this Security upon compliance by COMSAT
with certain conditions set forth therein.


Section 204.      Form of Trustee's Certificate of Authentication.

                  This  is  one  of  the  Securities  referred  to  in  the
within-mentioned Indenture.

                              THE SECURITIES


Section 301.      Title and Terms.

                  The aggregate principal amount of Securities which may be
authenticated  and delivered under this Indenture is  $206,200,000,  except
for Securities  authenticated  and delivered upon  registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section
304, 305, 306 or 906.

                  The  Securities  shall be  known  and  designated  as the
"81/8% Junior  Subordinated  Deferrable  Interest  Debentures  Due July 18,
2025" of the Company.  Their Stated  Maturity shall be the earliest of July
18, 2025 (subject to extension, as provided herein) or, except in the event
that (A) a Tax Event or an  Investment  Company  Event has occurred and the
General  Partner of COMSAT  Capital has elected to dissolve  COMSAT Capital
and cause the  Securities to be distributed to the holders of the Preferred
Securities in  liquidation of COMSAT Capital as provided in Clauses (ii) or
(iii) of Section 6.2(c) of the Limited Partnership  Agreement or (B) COMSAT
Capital is consolidated,  amalgamated, merged with or into, or replaced by,
or conveys,  transfers or leases its  properties  and assets as an entirety
to, any  corporation  or other body pursuant to Section 9.12 of the Limited
Partnership  Agreement,  the date upon which COMSAT  Capital is  dissolved,
wound-up,  liquidated or terminated (other than any termination  within the
meaning of section  708(b)(1)(B)  of the  Internal  Revenue Code of 1986 or
equivalent   provision  of  subsequent  law,  which  termination  does  not
constitute a termination of COMSAT Capital for any other purpose), and they
shall bear  interest at the rate of 81/8% per annum,  from July 18, 1995 or
from the most recent Interest  Payment Date to which interest has been paid
or duly provided for, as the case may be, payable monthly,  in arrears,  on
the last day of each calendar month of each year,  commencing July 31, 1995
until the principal thereof is paid or made available for payment. Interest
will  compound  monthly  and will accrue at the annual rate of 81/8% on any
interest installment that is not paid when due or during an extension of an
interest  payment  period as set forth  below in this  Section  301. In the
event that any date on which interest is payable on the Securities is not a
Business  Day,  then payment of the  interest  payable on such date will be
made on the next  succeeding  day which is a Business  Day (and without any
interest or other  payment in respect of any such delay),  except that,  if
such Business Day is in the next  succeeding  calendar  year,  such payment
shall be made on the immediately  preceding Business Day, in each case with
the same force and effect as if made on such date.



                                       21


<PAGE>



                  If at any time  COMSAT  Capital  shall be required to pay
any interest on dividends in respect of the Preferred  Securities  pursuant
to the terms  thereof,  then the  Company  will pay as  interest  to COMSAT
Capital as the holder of the Securities  Additional Interest.  In addition,
if COMSAT Capital would be required to pay any taxes,  duties,  assessments
or governmental  charges of whatever nature (other than withholding  taxes)
imposed by the United States, or any other taxing  authority,  then, in any
such case, the Company also will pay as Additional Interest such amounts as
shall be required so that the net amounts  received  and retained by COMSAT
Capital after paying any such taxes,  duties,  assessments or  governmental
charges  will be not less  than  the  amounts  COMSAT  Capital  would  have
received had no such taxes,  duties,  assessments or  governmental  charges
been imposed.  The  obligations of the Company under this  paragraph  shall
survive  any  satisfaction  and  discharge  or any  defeasance  pursuant to
Article Four hereof.

                  The Company may, by Company Order, prior to the Scheduled
Maturity Date,  extend the maturity date of the Securities no more than one
time,  for up to an additional 19 years from the Scheduled  Maturity  Date,
provided  that at the time of such  extension  (i) no Event of  Default  or
event which after notice or lapse of time,  or both,  would become an Event
of  Default  specified  in  Section  501(5) or  Section  501(6)  shall have
occurred and be  continuing;  (ii) the Company has made timely  payments of
interest  (including  Additional  Interest)  on the  Securities  during the
immediately preceding 18 months without deferrals;  (iii) COMSAT Capital is
not in arrears on payments of  distributions  on the Preferred  Securities;
(iv) the Securities shall continue to pay Interest at least at a rate equal
to the rate of distributions that accrue on the Preferred  Securities;  (v)
the Securities are rated  Investment  Grade; and (vi) the final maturity of
the  Securities  is not  later  than  the 49th  anniversary  of the date of
issuance of the Preferred Securities.

                  The Company shall have the right,  at any time during the
term of the Securities,  to extend the interest payment period from time to
time to a period not exceeding 60 consecutive months,  provided that during
the period of any such  extension,  interest  will  continue  to accrue and
compound monthly.  At the end of any such extended interest payment period,
the Company shall pay all interest then accrued and unpaid  (together  with
Additional  Interest  thereon);  provided  that  during  any such  extended
interest payment period COMSAT shall not declare or pay any dividend on, or
redeem,  purchase,  acquire or make a liquidation  payment with respect to,
any of its capital stock (other than as a result of a  reclassification  of
such capital  stock or the exchange or conversion of one class or series of
capital  stock for another class or series of capital  stock),  or make any
guarantee payments with respect to the foregoing (other than payments under
the  Parent  Guarantee).  Prior to the  termination  of any  such  extended
interest  payment  period,  the  Company may  further  extend the  interest
payment period, provided


                                       22


<PAGE>



that such extended  interest payment period together with all such previous
and further  extensions  thereof may not exceed 60  consecutive  months and
provided,  further,  that in no event shall any  extension  of the interest
payment period extend beyond the Stated Maturity of the  Securities.  After
the Company has paid all accrued and unpaid interest (including  Additional
Interest)  following  an extended  interest  payment  period,  it may again
extend interest payment periods for up to 60 consecutive months, subject to
the preceding  sentence.  If COMSAT Capital shall be the sole Holder of the
Securities,  COMSAT shall give COMSAT Capital notice of its selection of an
extended  interest  payment period one Business Day prior to the earlier of
(i) the date the dividends on the Preferred  Securities are payable or (ii)
the date  COMSAT  Capital is  required  to give notice to the NYSE or other
applicable  self-regulatory  organization  or to holders  of the  Preferred
Securities of the record date or the date such dividend is payable,  but in
any event not less than one Business Day prior to such record date.  COMSAT
shall cause  COMSAT  Capital to give notice of COMSAT's  selection  of such
extended   interest   payment  period  to  the  holders  of  the  Preferred
Securities.  If COMSAT  Capital is not the sole  Holder of the  Securities,
COMSAT shall give the Holders of the Securities  notice of its selection of
such an extended  interest  payment  period ten Business  Days prior to the
earlier  of (i) the  Interest  Payment  Date or (ii)  the  date  COMSAT  is
required  to give  notice to the NYSE or other  applicable  self-regulatory
organization, or to the Holders of the Securities, of the record or payment
date of such related interest  payment,  but in any event not less than two
Business Days prior to such record date.

                  The principal of and interest on the Securities issued as
a  global  security  will  be  made  to  DTC,  as the  depository  for  the
Securities.  The Trustee or the  Holders of not less than 25% in  aggregate
outstanding principal amount of the Securities may declare the principal of
and interest (including any Additional  Interest) on the Securities due and
payable immediately on any Event of Default; provided,  however, that after
such  acceleration,  but before a judgment or decree based on acceleration,
the  Holders of a majority in  aggregate  principal  amount of  outstanding
Securities  may,  under  certain  circumstances,  rescind  and  annul  such
acceleration  if all  Events of  Default,  other  than the  non-payment  of
accelerated  principal,  have  been  cured or  waived  as  provided  in the
Indenture.  Unless the Holder of the Preferred Securities is COMSAT Capital
(in which case payment of interest shall be made by wire transfer), payment
of interest may be made,  at the option of the Company,  by check mailed to
the address of the Persons entitled thereto as such address shall appear in
the Security Register.

                  The Securities  shall be subordinated in right of payment
to Senior Indebtedness as provided in Article Eleven.

                  The Securities shall be redeemable as provided in Article
Twelve.

Section 302.      Denominations.

                  The  Securities,  if  distributed to holders of Preferred
Securities in a dissolution of COMSAT Capital,  will initially be issued as
a global security.  If the Securities are issued in certificated form, such
Securities  will be issued only in registered form without coupons and only
in denominations of $25 and integral multiples thereof.


Section 303.      Execution, Authentication, Delivery and Dating.

                  The Securities shall be executed on behalf of the Company
by its Chairman of the Board, its Vice Chairman of the Board, its President
or one of its Vice Presidents,  under its corporate seal reproduced thereon
attested  by  its  Secretary  or  one of  its  Assistant  Secretaries.  The
signature  of any of these  officers  on the  Securities  may be  manual or
facsimile.

                  Securities bearing the manual or facsimile  signatures of
individuals  who were at any time the proper  officers of the Company shall
bind the Company, notwithstanding that such individuals or any of them have
ceased to hold such  offices  prior to the  authentication  and delivery of
such  Securities  or did  not  hold  such  offices  at  the  date  of  such
Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture,  the Company may deliver Securities executed by
the  Company to the  Trustee for  authentication,  together  with a Company
Order for the  authentication  and  delivery  of such  Securities;  and the
Trustee in  accordance  with such  Company  Order  shall  authenticate  and
deliver such Securities as in this Indenture provided and not otherwise.

                  Each   Security   shall   be   dated   the  date  of  its
authentication.

                  No Security  shall be entitled to any benefit  under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security a certificate  of  authentication  substantially  in the form
provided for herein executed by the Trustee by manual  signature,  and such
certificate  upon any Security shall be conclusive  evidence,  and the only
evidence,  that such  Security has been duly  authenticated  and  delivered
hereunder.


Section 304.      Temporary Securities.

                  Pending the  preparation  of definitive  Securities,  the
Company may execute,  and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed,


                                       24


<PAGE>



lithographed,  typewritten,  mimeographed  or  otherwise  produced,  in any
authorized  denomination,  substantially  of the  tenor  of the  definitive
Securities  in lieu of which  they are  issued  and with  such  appropriate
insertions,  omissions,  substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution of
such Securities.

                  If  temporary  Securities  are issued,  the Company  will
cause  definitive  Securities to be prepared  without  unreasonable  delay.
After the preparation of definitive  Securities,  the temporary  Securities
shall be  exchangeable  for  definitive  Securities  upon  surrender of the
temporary  Securities  at any  office or agency of the  Company  designated
pursuant to Section 1002, without charge to the Holder.  Upon surrender for
cancellation  of any one or more  temporary  Securities,  the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor
a  like   principal   amount  of   definitive   Securities   of  authorized
denominations.  Until so exchanged  the temporary  Securities  shall in all
respects  be  entitled  to  the  same  benefits  under  this  Indenture  as
definitive Securities.


Section 305.      Registration, Registration of Transfer and
                  Exchange.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register  (the  register  maintained in such office
and in any other office or agency designated pursuant to Section 1002 being
herein sometimes  collectively  referred to as the "Security  Register") in
which,  subject to such  reasonable  regulations as it may  prescribe,  the
Company shall provide for the  registration  of Securities and of transfers
of Securities. The Trustee is hereby appointed "Security Registrar" for the
purpose of  registering  Securities  and  transfers of Securities as herein
provided.

                  Upon  surrender  for  registration  of  transfer  of  any
Security  at an  office or agency of the  Company  designated  pursuant  to
Section 1002 for such purpose,  the Company shall execute,  and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations and
of a like aggregate principal amount.

                  At the option of the Holder,  Securities may be exchanged
for  other  Securities  of  any  authorized  denominations  and  of a  like
aggregate  principal  amount,  upon  surrender  of  the  Securities  to  be
exchanged  at  such  office  or  agency.  Whenever  any  Securities  are so
surrendered for exchange,  the Company shall execute, and the Trustee shall
authenticate  and  deliver,  the  Securities  which the  Holder  making the
exchange is entitled to receive.



                                       25


<PAGE>



                  All Securities  issued upon any  registration of transfer
or exchange of Securities  shall be the valid  obligations  of the Company,
evidencing  the same debt,  and  entitled to the same  benefits  under this
Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

                  Every Security  presented or surrendered for registration
of  transfer  or for  exchange  shall (if so required by the Company or the
Trustee) be duly endorsed,  or be  accompanied  by a written  instrument of
transfer,  in form satisfactory to the Company and the Security  Registrar,
duly  executed by the Holder  thereof or his attorney  duly  authorized  in
writing.

                  No service charge shall be made for any  registration  of
transfer or exchange of Securities,  but the Company may require payment of
a sum sufficient to cover any tax or other governmental  charge that may be
imposed in  connection  with any  registration  of  transfer or exchange of
Securities,  other than (i)  exchanges  pursuant  to Section 304 or 906 not
involving any transfer or (ii) transfers  contemplated by Section 6.2(c) or
9.12 of the Limited Partnership Agreement.


Section 306.      Mutilated, Destroyed, Lost and Stolen Securities.

                  If any mutilated  Security is surrendered to the Trustee,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange  therefor a new  Security of like tenor and  principal  amount and
bearing a number not contemporaneously Outstanding.

                  If  there  shall  be  delivered  to the  Company  and the
Trustee (i)  evidence to their  satisfaction  of the  destruction,  loss or
theft of any  Security  and  (ii)  such  security  or  indemnity  as may be
required  by them to save  each of them  and any  agent of  either  of them
harmless, then, in the absence of notice to the Company or the Trustee that
such Security has been acquired,by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such
destroyed,  lost or  stolen  Security,  a new  Security  of like  tenor and
principal amount and bearing a number not contemporaneously outstanding.

                  In case any such  mutilated,  destroyed,  lost or  stolen
Security has become or is about to become due and  payable,  the Company in
its discretion may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section,
the Company may require the payment of a sum sufficient to cover any tax or
other  governmental  charge that may be imposed in relation thereto and any
other expenses  (including the fees and expenses of the Trustee)  connected
therewith.



                                       26


<PAGE>



                  Every new  Security  issued  pursuant to this  Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional  contractual  obligation  of the  Company,  whether  or not  the
destroyed,  lost or stolen  Security  shall be at any time  enforceable  by
anyone, and shall be entitled to all the benefits of this Indenture equally
and  proportionately   with  any  and  all  other  Securities  duly  issued
hereunder.

                  The  provisions  of this Section are  exclusive and shall
preclude (to the extent  lawful) all other rights and remedies with respect
to the  replacement  or payment  of  mutilated,  destroyed,  lost or stolen
Securities.


Section 307.      Payment of Interest; Interest Rights Preserved.

                  Interest  on  any  Security  which  is  payable,  and  is
punctually  paid, on any Interest  Payment Date shall be paid to the Person
in whose name that  Security  (or one or more  Predecessor  Securities)  is
registered  at the close of business  on the  Regular  Record Date for such
interest,  which shall be the Business  Day next  preceding  such  Interest
Payment Date; provided,  however, that if the Securities shall not continue
to remain in  book-entry-only  form,  the  Company  shall have the right to
select  record dates which shall be more than one Business Day prior to the
Interest Payment Date.

                  Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest  Payment Date (herein
called  "Defaulted  Interest")  shall  forthwith cease to be payable to the
Holder on the  relevant  Regular  Record Date by virtue of having been such
Holder,  and such  Defaulted  Interest may be paid by the  Company,  at its
election in each case, as provided in Clause (1) or (2) below:

                  (1)  The  Company  may  elect  to  make  payment  of  any
Defaulted  Interest to the Persons in whose names the  Securities (or their
respective Predecessor  Securities) are registered at the close of business
on a Special Record Date for the payment of such Defaulted Interest,  which
shall be fixed in the  following  manner.  The  Company  shall  notify  the
Trustee in writing of the amount of Defaulted  Interest proposed to be paid
on each Security and the date of the proposed payment, and at the same time
the Company  shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted  Interest
or shall make  arrangements  satisfactory  to the Trustee for such  deposit
prior to the date of the proposed payment,  such money when deposited to be
held in trust for the  benefit of the Persons  entitled  to such  Defaulted
Interest as  provided in this  Clause.  Thereupon  the Trustee  shall fix a
Special Record Date for the payment of such Defaulted  Interest which shall
be not more than 15 days and not less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee
of the notice of the


                                       27


<PAGE>



proposed  payment.  The Trustee shall  promptly  notify the Company of such
Special  Record Date and,  in the name and at the  expense of the  Company,
shall cause notice of the proposed  payment of such Defaulted  Interest and
the Special Record Date therefor to be mailed, first-class postage prepaid,
to each Holder at his address as it appears in the Security  Register,  not
less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such  Defaulted  Interest and the Special  Record Date  therefor
having been so mailed, such Defaulted Interest shall be paid to the Persons
in whose names the Securities (or their respective Predecessor  Securities)
are  registered  at the close of business on such  Special  Record Date and
shall no longer be payable pursuant to the following Clause (2).

                  (2)  The  Company  may  make  payment  of  any  Defaulted
Interest in any other lawful manner not inconsistent  with the requirements
of any securities  exchange on which the Securities may be listed,  and, if
so listed, upon such notice as may be required by such exchange,  if, after
notice given by the Company to the Trustee of the proposed payment pursuant
to this Clause,  such manner of payment shall be deemed  practicable by the
Trustee.

                  Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other  Security shall carry the rights to
interest  accrued and unpaid,  and to accrue  (including  in each such case
Additional Interest), which were carried by such other Security.


Section 308.      Persons Deemed Owners.

                  Prior to due  presentment of a Security for  registration
of transfer,  the Company,  the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such  Security is  registered as
the  owner  of such  Security  for the  purpose  of  receiving  payment  of
principal of and (subject to Section 307)  interest  (including  Additional
Interest) on such Security and for all other purposes  whatsoever,  whether
or not such Security be overdue,  and neither the Company,  the Trustee nor
any agent of the Company or the Trustee  shall be affected by notice to the
contrary.


Section 309.      Cancellation.

                  All  Securities  surrendered  for  payment,   redemption,
registration  of transfer or exchange  shall,  if surrendered to any Person
other than the  Trustee,  be delivered to the Trustee and shall be promptly
cancelled  by it. The  Company  may at any time  deliver to the Trustee for
cancellation  any  Securities   previously   authenticated   and  delivered
hereunder which the Company may have acquired in any manner whatsoever, and
all Securities so


                                       28


<PAGE>



delivered shall be promptly  cancelled by the Trustee.  No Securities shall
be authenticated in lieu of or in exchange for any Securities  cancelled as
provided in this Section,  except as expressly permitted by this Indenture.
All  cancelled  Securities  held by the  Trustee  shall be  disposed  of as
directed by a Company Order.


Section 310.      Computation of Interest.

                  Interest on the Securities shall be computed on the basis
of a 360-day year of twelve 30-day months and, for any period  shorter than
a full  monthly  interest  period,  shall be  computed  on the basis of the
actual number of days elapsed in such period.

Certificate  and an Opinion of Counsel,  each stating  that all  conditions
precedent herein provided for relating to the satisfaction and discharge of

obligations  of the Company to the Trustee  under Section 607 and, if money
shall have been  deposited  with the Trustee  pursuant to subclause  (B) of
Clause (1) of this Section or if money and/or U.S.  Government  Obligations
shall have been  deposited  with the Trustee  pursuant to Section  403, the
obligations  of the Trustee  under  Section 402 and the last  paragraph  of
Section 1003 shall survive.

own Paying  Agent) as the Trustee may  determine,  to the Persons  entitled
thereto,  of the  principal  and  interest,  if any, for whose payment such
money has been deposited with the Trustee.

                  The Trustee shall deliver or pay to the Company from time
to time upon Company Request any money and/or U.S.


                                       30

Government  Obligations held by it as provided in Section 402 or in Section
403 which,  in the opinion of a nationally  recognized  firm of independent
public accountants  expressed in a written  certification thereof delivered
to the Trustee,  are then in excess of the amount  thereof which then would
have been  required  to be  deposited  for the purpose for which such money
and/or U.S. Government Obligations were deposited or received.

Section 403.      Defeasance and Discharge of Indenture.

                  (1)  Notwithstanding  the  provisions  of Section 401 but
subject  to Section  403(2),  the  Company  shall  have the  option,  to be
exercised by Board Resolution, to pay and discharge the entire indebtedness
on all the Outstanding  Securities;  provided that the following conditions
have been satisfied:

                             (A)  the Company shall have irrevocably deposited
in trust with the  Trustee as trust  funds,  for the  purpose of making the
following  payments,  specifically  pledged as security  for, and dedicated
solely  to,  the  benefit  of Holders  of  Securities,  money  and/or  U.S.
Government Obligations for the payment of principal and each installment of
interest  on the  Securities  on their  respective  Stated  Maturities,  in
accordance with this Indenture and the Securities;

                             (B)  the Company shall have delivered to the
Trustee  a  certificate  (addressed  to  the  Trustee)  from  a  nationally
recognized  firm of independent  certified  public  accountants  expressing
their  opinion  that the payment of  principal  and  interest  when due and
without reinvestment on the deposited U.S. Government  Obligations plus any
deposited  money without  investment will provide cash at such times and in
such  amounts  (but,  in the case of the option to defease  the debt in its
entirety  only,  not more than such  amounts) as will be  sufficient to pay
principal  and  each   installment  of  interest  on  all  the  Outstanding
Securities on their respective Stated  Maturities,  in accordance with this
Indenture and the Securities;

                             (C)  91 days pass after the deposit is made or,
if longer,  the day  following  the  expiration  of the longest  preference
period  applicable  to the  Company in respect of such  deposit  occurs (it
being  understood  that the  condition  in this  clause (C) is a  condition
subsequent and shall not be deemed  satisfied  until the expiration of such
period),  and during  such  period no Event of Default or event which after
notice  or  lapse  of  time,  or both,  would  become  an Event of  Default
specified in Section 501(5) or Section 501(6) occurs which is continuing at
the end of the period;

                             (D)  no Event of Default or event which after
notice or lapse of time,  or both,  would  become an Event of  Default  has
occurred  and is  continuing  on the date of such  deposit and after giving
effect thereto;

<PAGE>



                             (E)  the exercise of the defeasance options does
not constitute a default under, or a breach or violation of, this Indenture
or any other  agreement or instrument to which the Company is a party or by
which it is bound;

                             (F)  the Company delivers to the Trustee an
Opinion of Counsel to the effect that the trust  resulting from the deposit
does not  constitute,  or is qualified as, a regulated  investment  company
under the Investment Company Act of 1940;

                             (G)  the Company delivers to the Trustee an
Opinion of Counsel to the effect  that the Company has  received  from,  or
there has been published by, the United States  Internal  Revenue Service a
ruling,  or since the date of this Indenture there has been a change in tax
law in either case to the effect that,  and based thereon such opinion will
confirm  that,  holders of Securities  will not recognize  gain or loss for
federal  income tax purposes as a result of such  deposit,  defeasance  and
discharge and will be subject to federal income tax on the same amount,  in
the same  manner  and at the same time as would  have been the case if such
deposit, defeasance and discharge was not to occur;

                             (H)  the Company shall have delivered to the
Trustee an Officers'  Certificate to the effect that such defeasance  shall
not cause any Securities then listed on any registered  national securities
exchange  under the  Securities  Exchange  Act of 1934,  as amended,  to be
delisted;

                             (I)  such defeasance shall not cause the Trustee
for the  Securities to have a conflicting  interest as specified in Section
608 or for the  purposes  of the Trust  Indenture  Act with  respect to any
securities of the Company;

                             (J)  the Company shall have delivered to the
Trustee an Officers'  Certificate  and an Opinion of Counsel,  each stating
that  all  conditions  precedent  and  subsequent  to  the  defeasance  and
discharge  of the entire  indebtedness  on all  Outstanding  Securities  as
contemplated by this Section 403 have been complied with;

                             (K)      at the time of such deposit:  (i) no
default in the payment of all or a portion of principal of (or premium,  if
any) or  interest on any Senior  Indebtedness  shall have  occurred  and be
continuing, and no event of default with respect to any Senior Indebtedness
shall have  occurred  and be  continuing  and shall have  resulted  in such
Senior Indebtedness becoming or being declared due and payable prior to the
date on which it would  otherwise  have  become due and payable and (ii) no
other event of default with respect to any Senior  Indebtedness  shall have
occurred and be continuing  permitting  (after notice or the lapse of time,
or both) the holders of such Senior Indebtedness (or a trustee on behalf of
the holders  thereof) to declare such Senior  Indebtedness  due and payable
prior to the


                                       32


<PAGE>



date on which it would  otherwise  have become due and payable,  or, in the
case of either Clause (i) or Clause (ii) above,  each such default or event
of default  shall have been cured or waived or shall have  ceased to exist;
and

                             (L)      Such defeasance shall not result in the
trust  arising  from such deposit  constituting  an  investment  company as
defined in the  Investment  Company Act of 1940, as amended,  or such trust

Securities,  by written notice to the Company and the Trustee,  may rescind
and annul such acceleration if

                  (1)        the Company has paid or deposited with the
Trustee a sum sufficient to pay

                  the Securities,

                  disbursements and advances of the Trustee, its agents and
                  counsel;

and

                  (2) all Events of Default,  other than the non-payment of
the  principal  of  Securities   which  have  become  due  solely  by  such
declaration  of  acceleration,  have been  cured or waived as  provided  in

                  No such rescission shall affect any subsequent default or

Section 503.      Collection of Indebtedness and Suits for
                  Enforcement by Trustee.

                  The Company covenants that if

                  (1)  default  is  made  in the  payment  of any  interest
(including  any  Additional  Interest) on any Security  when such  interest
becomes due and payable and such default continues for a period of 30 days,
or

                  (2)        default is made in the payment of the principal
of any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such  Securities,  the whole  amount then due and payable on
such  Securities  for  principal  and interest  (including  any  Additional
Interest),  and,  to the  extent  that  payment  thereof  shall be  legally
enforceable,  interest on any overdue principal and on any overdue interest
(including any Additional  Interest),  at the rate borne by the Securities,
and, in addition  thereto,  such further  amount as shall be  sufficient to
cover  the costs and  expenses  of  collection,  including  the  reasonable
compensation,  expenses,  disbursements  and advances of the  Trustee,  its
agents and counsel.

                  If an Event of  Default  occurs  and is  continuing,  the
Trustee may in its discretion proceed to protect and enforce its rights and
the rights of the Holders by such appropriate  judicial  proceedings as the
Trustee  shall deem most  effectual to protect and enforce any such rights,
whether for the specific  enforcement  of any covenant or agreement in this
Indenture or in aid of the


                                       36

exercise of any power granted herein, or to enforce any other
proper remedy.


Section 504.      Trustee May File Proofs of Claim.

                  In  case  of  any  judicial  proceeding  relative  to the
Company (or any other  obligor  upon the  Securities),  its property or its
creditors,  the Trustee shall be entitled and empowered, by intervention in
such proceeding or otherwise,  to take any and all actions authorized under
the Trust  Indenture  Act in order to have  claims of the  Holders  and the
Trustee allowed in any such proceeding. In particular, the Trustee shall be
authorized to collect and receive any moneys or other  property  payable or
deliverable  on any  such  claims  and to  distribute  the  same;  and  any
custodian,  receiver, assignee, trustee, liquidator,  sequestrator or other
similar  official in any such judicial  proceeding is hereby  authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee  shall  consent  to the  making of such  payments  directly  to the
Holders,  to  pay to the  Trustee  any  amount  due it for  the  reasonable
compensation,  expenses,  disbursements  and advances of the  Trustee,  its
agents and counsel,  and any other  amounts due the Trustee  under  Section
607.

                  No  provision  of  this  Indenture  shall  be  deemed  to
authorize  the  Trustee  to  authorize  or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof or
to  authorize  the Trustee to vote in respect of the claim of any Holder in
any such proceeding.


Section 505.      Trustee May Enforce Claims Without Possession of
                  Securities.

                  All rights of action and claims  under this  Indenture or
the Securities  may be prosecuted  and enforced by the Trustee  without the
possession  of any of the  Securities  or  the  production  thereof  in any
proceeding  relating  thereto,  and any such  proceeding  instituted by the
Trustee  shall be brought  in its own name as trustee of an express  trust,
and any recovery of judgment shall,  after provision for the payment of the
reasonable  compensation,  expenses,  disbursements  and  advances  of  the
Trustee,  its agents and counsel, be for the ratable benefit of the Holders
of the Securities in respect of which such judgment has been recovered.


Section 506.      Application of Money Collected.

                  Subject to Article Eleven, any money collected by the
Trustee pursuant to this Article shall be applied in the


                                       37


<PAGE>



following  order, at the date or dates fixed by the Trustee and, in case of
the distribution of such money on account of principal, premium, if any, or
interest  (including any Additional  Interest),  upon  presentation  of the
Securities  and the notation  thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

                  First:     To the payment of all amounts due the Trustee
under Section 607; and

                  Second: To the payment of the amounts then due and unpaid
for principal of and interest  (including any  Additional  Interest) on the
Securities  in respect of which or for the  benefit of which such money has
been  collected,  ratably,  without  preference  or  priority  of any kind,
according to the amounts due and payable on such  Securities  for principal
and interest (including any Additional Interest), respectively.


Section 507.      Limitation on Suits.

                  No  Holder  of  any  Security  will  have  any  right  to
institute any proceeding with respect to this Indenture,  or for any remedy
hereunder, unless

                  (1)        such Holder shall have previously given written
notice to the Trustee of a continuing Event of Default;

                  (2)  if  COMSAT   Capital  is  not  the  sole  Holder  of
Securities,  the Holders of at least 25% in aggregate  principal  amount of
the Outstanding  Securities  shall have made written request to the Trustee
to institute  such  proceedings  in respect of such Event of Default in its
own name as Trustee hereunder;

                  (3) such  Holder or  Holders  shall  have  offered to the
Trustee reasonable indemnity against the costs, expenses and liabilities to
be incurred in compliance with such request;

                  (4) the Trustee  shall not have received from the Holders
of a majority in aggregate principal amount of the Outstanding Securities a
direction inconsistent with such written request; and

                  (5)        the Trustee, for 60 days after its receipt of
such notice, request and offer of indemnity, has failed to
institute any such proceeding;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or prejudice the rights of any other
Holders,  or to obtain or to seek to obtain priority or preference over any
other Holders or to enforce any right under this  Indenture,  except in the
manner herein provided and for the equal and ratable benefit of all the


                                       38


<PAGE>



Holders. However, the limitations contained in the previous sentence do not
apply to a suit  instituted  by a Holder of a Security for  enforcement  of
payment  of  principal  of or  interest  on such  Security  on or after the
respective due dates expressed in such Security.


Section 508.      Unconditional Right of Holders to Receive
                  Principal and Interest.

                  Notwithstanding  any other  provision in this  Indenture,
the Holder of any  Security  shall have the right,  which is  absolute  and
unconditional,  to receive  payment of the  principal  of and  (subject  to
Section 307) interest (including any Additional  Interest) on such Security
on the respective Stated Maturities  expressed in such Security (or, in the
case of redemption,  on the Redemption  Date) and to institute suit for the
enforcement  of any such  payment,  and such  rights  shall not be impaired
without the consent of such Holder.


Section 509.      Restoration of Rights and Remedies.

                  If  the  Trustee  or  any  Holder  has   instituted   any
proceeding  to enforce any right or remedy  under this  Indenture  and such
proceeding has been  discontinued or abandoned for any reason,  or has been
determined  adversely to the Trustee or to such  Holder,  then and in every
such case,  subject to any  determination in such proceeding,  the Company,
the Trustee and the Holders shall be restored severally and respectively to
their former positions  hereunder and thereafter all rights and remedies of
the Trustee and the Holders shall continue as though no such proceeding had
been instituted.


Section 510.      Rights and Remedies Cumulative.

                  Except  as  otherwise   provided   with  respect  to  the
replacement or payment of mutilated,  destroyed,  lost or stolen Securities
in the last  paragraph of Section 306, no right or remedy herein  conferred
upon or  reserved  to the  Trustee  or to the  Holders  is  intended  to be
exclusive of any other right or remedy,  and every right and remedy  shall,
to the extent  permitted  by law,  be  cumulative  and in addition to every
other right and remedy given hereunder or now or hereafter  existing at law
or in equity or  otherwise.  The  assertion or  employment  of any right or
remedy hereunder, or otherwise,  shall not prevent the concurrent assertion
or employment of any other appropriate right or remedy.


Section 511.      Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of
any Security to exercise any right or remedy accruing upon any


                                       39


<PAGE>



Event of Default  shall  impair any such  right or remedy or  constitute  a
waiver of any such Event of Default or an acquiescence therein. Every right
and remedy given by this Article or by law to the Trustee or to the Holders
may be  exercised  from  time  to  time,  and  as  often  as may be  deemed
expedient, by the Trustee or by the Holders, as the case may be.


Section 512.      Control by Holders.

                  The Holders of a majority in aggregate  principal  amount
of the  Outstanding  Securities  shall  have the right to direct  the time,
method and place of conducting any  proceeding for any remedy  available to
the Trustee or  exercising  any trust or power  conferred  on the  Trustee,
provided that

                  (1)        such direction shall not be in conflict with any
rule of law or with this Indenture;

                  (2) subject to the provisions of Section 601, the Trustee
shall have the right to decline to follow any such direction if the Trustee
determines  that the action so directed may not be lawfully  taken, or if a
Responsible  Officer or  Officers  determines  that the action so  directed
would be unjustly  prejudicial to the Holders of Securities not taking part
in such direction or would involve the Trustee in personal liability; and

                  (3) the Trustee may take any other action  deemed  proper
by the Trustee which is not inconsistent with such direction.


Section 513.      Waiver of Past Defaults.

                  Subject to Section 1006  hereof,  the holders of not less
than a majority in aggregate outstanding principal amount of the Securities
may, on behalf of the holders of all the Securities, waive any past default
hereunder and its consequences, except a default

                  (1)        in the payment of the principal or interest
(including any Additional Interest) on any Security; or

                  (2) in respect of a covenant or  provision  hereof  which
under Article Nine cannot be modified or amended without the consent of the
Holder of each Outstanding Security affected.

                  Upon any such waiver,  such default shall cease to exist,
and any Event of  Default  arising  therefrom  shall be deemed to have been
cured, for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other default or impair any right consequent thereon.

Section 514.      Undertaking for Costs.

                  In any suit for the  enforcement  of any  right or remedy
under this  Indenture,  or in any suit  against  the Trustee for any action
taken,  suffered or omitted by it as Trustee, a court may require any party
litigant in such suit to file an undertaking to pay the costs of such suit,
and may assess costs against any such party litigant,  in the manner and to
the extent provided in the Trust Indenture Act; provided, that neither this
Section nor the Trust  Indenture Act shall be deemed to authorize any court
to require such an  undertaking  or to make such an  assessment in any suit
instituted by the Company or in any suit for the  enforcement  of the right
to  receive  the  principal  of  and  interest  (including  any  Additional
Interest) on any Security.


Section 515.      Waiver of Stay or Extension Laws.

                  The Company covenants (to the extent that it may lawfully
do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension
law wherever  enacted,  now or at any time  hereafter  in force,  which may
affect the covenants or the performance of this Indenture;  and the Company
(to the extent  that it may  lawfully  do so) hereby  expressly  waives all
benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the  execution of any power herein  granted to the Trustee,
but will suffer and permit the  execution  of every such power as though no
such law had been enacted.



                                ARTICLE SIX

                                THE TRUSTEE


Section 601.      Certain Duties and Responsibilities.

                  The  Trustee,  prior  to the  occurrence  of an  Event of
Default  with respect to  Securities  and after the curing of all Events of
Default with respect to Securities which may have occurred, shall undertake
to perform with respect to Securities only such duties as are  specifically
set forth in this  Indenture  and no implied  covenants  shall be read into
this  Indenture  against  the  Trustee.  In case an Event of  Default  with
respect to  Securities  has occurred  (which has not been cured or waived),
the Trustee shall  exercise  with respect to Securities  such of the rights
and powers vested in it by this Indenture,  and use the same degree of care
and skill in their exercise,  as a prudent individual would exercise or use
under the circumstances in the conduct of his or her own affairs.

<PAGE>



                  No  provision  of this  Indenture  shall be  construed to
relieve the Trustee from  liability for its own negligent  action,  its own
negligent failure to act, or its own willful misconduct, except that:

                  (a)        prior to the occurrence of an Event of Default
with respect to Securities and after the curing or waiving of all
such Events of Default which may have occurred:

                  (1) the duties and  obligations of the Trustee shall with
respect to the Securities be determined solely by the express provisions of
this  Indenture,  and the Trustee  shall not be liable with respect to such
Securities except for the performance of such duties and obligations as are
specifically  set forth in this  Indenture,  and no  implied  covenants  or
obligations shall be read into this Indenture against the Trustee; and

                  (2) in  the  absence  of bad  faith  on the  part  of the
Trustee,  the  Trustee  may  conclusively  rely,  as to  the  truth  of the
statements and the correctness of the opinions expressed therein,  upon any
certificates  or opinions  furnished to the Trustee and  conforming  to the
requirements of this Indenture; but in the case of any such certificates or
opinions  which by any  provision  hereof are  specifically  required to be
furnished to the Trustee,  the Trustee shall be under a duty to examine the
same to determine  whether or not they conform to the  requirements of this
Indenture;

                  (b) the  Trustee  shall  not be  liable  for any error of
judgment  made  in good  faith  by a  Responsible  Officer  or  Responsible
Officers  of the  Trustee,  unless it shall be proved  that the Trustee was
negligent in ascertaining the pertinent facts;

                  (c) the Trustee  shall not be liable with  respect to any
action taken or omitted to be taken by it in good faith in accordance  with
the  direction  of the  Holders  of not less than a majority  in  principal
amount of the  Securities  at the time  Outstanding  relating  to the time,
method and place of conducting any  proceeding for any remedy  available to
the Trustee,  or exercising  any trust or power  conferred upon the Trustee
under this Indenture with respect to the Securities; and

                  (d) none of the  provisions  contained in this  Indenture

indenture,  to the Holders of all Outstanding the Securities as their names
and  addresses  appear  upon the  Securities  Register.  Any failure of the

Section 903.      Execution of Supplemental Indentures.

                  In executing,  or accepting the additional trusts created
by,  any   supplemental   indenture   permitted  by  this  Article  or  the

Counsel  stating  that the  execution  of such  supplemental  indenture  is
authorized or permitted by this Indenture. Upon the request of the Company,
accompanied  by a Board  Resolution  authorizing  the execution of any such
supplemental indenture, and upon the filing with the Trustee of evidence of
the consent of Holders of the  Securities  required  to consent  thereto as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental  indenture  unless  such  supplemental  indenture  affects the
Trustee's  own  rights,  duties  or  immunities  under  this  Indenture  or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture.


Section 904.      Effect of Supplemental Indentures.

                  Upon the execution of any  supplemental  indenture  under
this Article, this Indenture shall be modified in accordance therewith, and

purposes;  and the respective rights,  limitations of rights,  obligations,
duties and immunities under this Indenture of the Trustee,  the Company and
the Holders of Securities  shall  thereafter be  determined,  exercised and
enforced  hereunder  subject  in all  respects  to such  modifications  and
amendments.

                  Every  supplemental  indenture  executed pursuant to this
Article shall conform to the requirements of the Trust Indenture Act.

                  Indentures.

                  Securities   authenticated   and   delivered   after  the
execution of any supplemental indenture pursuant to this Article may bear a
notation in form  approved  by the  Company,  provided  such form meets the
requirements of any exchange upon which the Securities may be listed, as to
any matter  provided  for in such  supplemental  indenture.  If the Company
shall so  determine,  new  Securities  so modified  as to  conform,  in the
opinion of the Board of Directors,  to any such supplemental  indenture may
be prepared and executed by the Company and  authenticated and delivered by
the Trustee in exchange for Outstanding Securities.

                 COVENANTS; REPRESENTATIONS AND WARRANTIES

                  The Company will duly and  punctually  pay or cause to be
paid the principal of and interest on the Securities in accordance with the
terms of the Securities and this Indenture.


Section 1002.     Maintenance of Office or Agency.

                  The  Company  will  maintain  in The  City of New York an
office or agency (i) where  Securities may be presented or surrendered  for
payment,  (ii) where  Securities may be  surrendered  for  registration  of
transfer or  exchange,  and (iii) where  notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served.  The
Company will give prompt written notice to the Trustee of the location, and
any change in the  location,  of such office or agency.  If at any time the
Company shall fail to maintain any such required  office or agency or shall
fail to furnish the Trustee with the address thereof,  such  presentations,
surrenders,  notices  and  demands  may be made or served at the  Corporate
Trust Office of the Trustee, and the Company hereby appoints the Trustee as
its  agent to  receive  all such  presentations,  surrenders,  notices  and
demands.

                  The Company may also from time to time  designate  one or
more other  offices or agencies  (in or outside The City of New York) where
the Securities may be presented or surrendered for any or all such purposes
and may from time to time rescind  such  designations;  provided,  however,
that no such  designation  or  rescission  shall in any manner  relieve the
Company of its  obligation  to  maintain an office or agency in The City of
New York for such purposes.  The Company will give prompt written notice to
the Trustee of any such  designation or rescission and of any change in the
location of any such other office or agency.


Section 1003.     Money for Securities Payments to Be Held in
Trust.

                  If the  Company  shall at any time act as its own  Paying
Agent,  it will, on or before each due date of the principal of or interest
on any of the  Securities,  segregate  and hold in trust for the benefit of
the Persons  entitled  thereto a sum  sufficient  to pay the  principal  or
interest so becoming  due until such sums shall be paid to such  Persons or

                  Whenever  the  Company  shall  have  one or  more  Paying
Agents,  it will, prior to each due date of the principal of or interest on
any  Securities,  deposit with a Paying Agent a sum  sufficient to pay such
amount,  such sum to be held as provided by the Trust  Indenture  Act,  and
(unless such Paying Agent is the Trustee) the Company will promptly  notify
the Trustee of its action or failure so to act.

                  The Company  will cause each Paying  Agent other than the
Trustee to execute and deliver to the Trustee an  instrument  in which such
Paying Agent shall agree with the  Trustee,  subject to the  provisions  of
this Section, that such Paying Agent will (i) comply with the provisions of
the Trust  Indenture Act applicable to it as a Paying Agent and (ii) during
the  continuance  of any default by the Company (or any other  obligor upon
the  Securities) in the making of any payment in respect of the Securities,
upon the written  request of the Trustee,  forthwith pay to the Trustee all
sums held in trust by such Paying Agent as such.

                  The Company may at any time, for the purpose of obtaining
the  satisfaction and discharge of this Indenture or for any other purpose,
pay, or by Company Order direct any Paying Agent to pay, to the Trustee all
sums held in trust by the  Company or such  Paying  Agent,  such sums to be
held by the Trustee upon the same trusts as those upon which such sums were
held by the Company or such Paying  Agent;  and,  upon such  payment by any
Paying Agent to the Trustee,  such Paying Agent shall be released  from all
further liability with respect to such money.

                  Any money deposited with the Trustee or any Paying Agent,
or then held by the Company,  in trust for the payment of the  principal of
(or premium,  if any) or interest on any Security and  remaining  unclaimed
for two years after such  principal  or interest has become due and payable
shall be paid to the  Company on Company  Request,  or (if then held by the
Company)  shall be  discharged  from  such  trust;  and the  Holder of such
Security shall thereafter,  as an unsecured general creditor,  look only to
the Company for payment  thereof,  and all liability of the Trustee or such
Paying  Agent with respect to such trust  money,  and all  liability of the
Company as trustee thereof, shall thereupon cease.


Section 1004.     Statement by Officers as to Default.

                  The Company will deliver to the Trustee, on or before May
15 in each calendar year in which any of the Securities are Outstanding, or
on or before  such other day in each  calendar  year as the Company and the
Trustee may from time to time agree upon, an Officers' Certificate, stating
whether or not to the best knowledge of the signers  thereof the Company is
in  default  in the  performance  and  observance  of  any  of  the  terms,
provisions and conditions of this Indenture  (without  regard to any period
of grace or requirement of notice provided hereunder) and, if the


                                       55


<PAGE>



Company  shall be in default,  specifying  all such defaults and the nature
and status thereof of which they may have knowledge.


Section 1005.     Existence.

                  Subject to Article Eight, the Company will do or cause to
be done all things  necessary to preserve and keep in full force and effect
its existence,  rights  (charter and statutory) and  franchises;  provided,
however,  that the Company shall not be required to preserve any such right
or  franchise  if  the  Board  of  Directors   shall   determine  that  the
preservation  thereof is no longer desirable in the conduct of the business
of the  Company  and that the loss  thereof is not  disadvantageous  in any
material respect to the Holders.


Section 1006.     Additional Covenants.

                  The Company  agrees it will not,  directly or indirectly,
declare  or pay any  dividend  on, or redeem,  purchase,  acquire or make a
distribution  or  liquidation  payment  with  respect to, any of its Common
Stock or preferred stock (other than as a result of a  reclassification  of
such Common Stock or preferred  stock or the exchange or  conversion of one
class or series of Common  Stock or  preferred  stock for another  class or
series of Common Stock or preferred stock), or make any guarantee  payments
with  respect  to the  foregoing,  if at such  time (a)  there  shall  have
occurred any event that,  with the giving of notice or the lapse of time or
both, would constitute an Event of Default hereunder, (b) the Company shall
be in default  with  respect to its  payment of any  obligations  under the
Parent  Guarantee  or (c)  the  Company  shall  have  given  notice  of its
selection of an extended  interest  payment  period as provided  herein and
such period,  or any extension  thereof,  shall be continuing.  The Company
also covenants (i) to remain the sole General Partner of COMSAT Capital and
maintain  100%  ownership  of the general  partnership  interests  thereof;
provided  that any  permitted  successor of the Company under Article Eight
may succeed to the Company's duties as General Partner,  (ii) to contribute
capital  in  an  amount  equal  to  at  least  3%  of  the  total   capital
contributions to COMSAT Capital, (iii) not to voluntarily dissolve, wind-up
or terminate COMSAT Capital,  except in connection with the distribution of
Securities to the holders of Preferred  Securities in liquidation of COMSAT
Capital  pursuant  to  Section  6.2(c) or 9.12 of the  Limited  Partnership
Agreement  and  in  connection  with  certain  mergers,  consolidations  or
amalgamations  permitted  by the  Limited  Partnership  Agreement,  (iv) to
perform timely all of its duties as General Partner  (including the duty to
declare and pay Dividends on the Preferred Securities),  and (v) to use its
reasonable efforts to cause COMSAT Capital to remain a limited  partnership
except in connection with certain mergers,  consolidations or amalgamations
permitted by the Limited  Partnership  Agreement  and otherwise to continue
not to be treated

as an association taxable as a corporation for United States
federal income tax purposes.

                  The Company also covenants that so long as any Securities
are held by COMSAT  Capital,  the General  Partner shall not (i) direct the
time,  method  and  place  of  conducting  any  proceeding  for any  remedy
available to the Trustee,  or executing any trust or power conferred on the
Trustee with respect to the  Securities,  (ii) waive any past default which
is waivable  under this  Indenture,  (iii) exercise any right to rescind or
annul a declaration  that the principal of all the Securities  shall be due
and payable, or (iv) consent to any amendment,  modification or termination
of this Indenture,  where such consent shall be required,  without, in each
case,  obtaining  the prior  approval of the holders of at least 66 2/3% or
more  in   liquidation   preference  of  the  Preferred   Securities   then
outstanding,  provided,  however, that where a consent under this Indenture
would require the consent of each Holder affected thereby,  no such consent
shall be given by the General  Partner  without  the prior  consent of each
holder of the Preferred  Securities.  The General  Partner shall not revoke
any action  previously  authorized  or approved by a vote of the  Preferred
Securities,  without the  approval of the holders of  Preferred  Securities
representing 66 2/3% or more of the aggregate liquidation preference of the
Outstanding  Preferred  Securities.  The General  Partner  shall notify all
holders of the Preferred  Securities of any notice of default received from
the Trustee with respect to the Securities.

                  The Company also  covenants  that if the  Securities  are
distributed to the holders of the Preferred Securities upon the dissolution
of  COMSAT  Capital,  the  Company  will use its best  efforts  to list the
Securities  on  the  NYSE  or on  such  other  exchange  as  the  Preferred
Securities  are  then  listed  and  traded  on the  same  part of any  such
exchange.

Section 1102.     Payment Over of Proceeds Upon Dissolution, Etc.

                  Upon any  payment by, or  distribution  of assets of, the
Company to  creditors  upon any  dissolution,  winding-up,  liquidation  or
reorganization  of the  Company,  whether  voluntary or  involuntary  or in
bankruptcy, insolvency,  receivership or other proceedings, all amounts due
or to become due upon all Senior  Indebtedness shall first be paid in full,
or payment  thereof  provided  for in money in  accordance  with its terms,
before the Holders of the Securities are entitled to receive any payment or
distribution  of any  kind  or  character  whether  in  cash,  property  or
securities, on account of the principal of or interest on the Securities or
on account of any purchase,  redemption or other  acquisition of Securities
by the Company,  any  Subsidiary of the Company,  the Trustee or any Paying
Agent  (all  such  payments,  distributions,   purchases,  redemptions  and
acquisitions  herein  referred  to,  individually  and  collectively,  as a
"Securities  Payment");  any payment by, or  distribution of assets of, the
Company of any kind or character,  whether in cash, property or securities,
by set-off or  otherwise,  to which the  Holders of the  Securities  or the
Trustee  would be entitled but for the  provisions of this Article shall be
paid by the Company or by any liquidating  trustee or agent or other Person
making such payment or distribution, or by the Holders of the Securities or
by the Trustee under this Indenture if received by them or it,  directly to
the   holders   of  Senior   Indebtedness   or  their   representative   or
representatives  or to the trustee or trustees  under any  indenture  under
which any instruments  evidencing any of such Senior  Indebtedness may have
been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Senior  Indebtedness  held or  represented  by each,  to the
extent  necessary  to pay all Senior  Indebtedness  in full,  after  giving
effect  to  any   concurrent   payment  to  the   holders  of  such  Senior
Indebtedness.

                  In  the  event  that,   notwithstanding   the   foregoing
provisions of this Section, the Trustee or the Holder of any Security shall
have received any payment or  distribution  of assets of the Company of any
kind or character,  whether in cash, property or securities,  prohibited by
the  foregoing  before all Senior  Indebtedness  is paid in full or payment
thereof  provided  for in cash,  then and in such  event  such  payment  or
distribution  shall be paid over or  delivered  forthwith to the trustee in

decree of a court of competent jurisdiction in a reorganization  proceeding
under any applicable  bankruptcy law or of any other  corporation  provided
for  by  such  plan  of  reorganization  or  readjustment  which  stock  or
securities  are  subordinated  in right of payment to all then  outstanding
Senior  Indebtedness  to  substantially  the same  extent,  or to a greater
extent  than,  the  Securities  are so  subordinated  as  provided  in this
Article.  The  consolidation  of the  Company  with,  or the  merger of the
Company into,  another  Person or the  liquidation  or  dissolution  of the
Company following the conveyance or transfer of all or substantially all of
its  properties  and assets as an entirety to another Person upon the terms
and  conditions  set forth in Article  Eight  hereof  shall not be deemed a
dissolution,  winding-up, liquidation or reorganization for the purposes of
this Section 1102 if the Person formed by such  consolidation or into which
the  Company  is merged or the  Person  which  acquires  by  conveyance  or
transfer such  Properties and assets,  as the case may be, shall, as a part
of such  consolidation,  merger,  conveyance  or transfer,  comply with the
conditions set forth in Article Eight.


Section 1103.     No Payment When Senior Indebtedness in Default.

                  In the event that any Senior Payment  Default (as defined
below) shall have occurred,  then no Securities  Payment shall be made, nor
shall any  property  of the  Company or any  Subsidiary  of the  Company be
applied to the  purchase,  acquisition,  retirement  or  redemption  of the
Securities,  unless and until such Senior  Payment  Default shall have been
cured or waived in  writing or shall  have  ceased to exist or all  amounts
then due and  payable  in respect of such  Senior  Indebtedness  (including
amounts  that have become and remain due by  acceleration)  shall have been
paid in full in cash. "Senior Payment Default" means (a) any default in the
payment of  principal,  premium,  interest or any other  payment due on any
Senior  Indebtedness  continuing  beyond  the  period  of  grace,  if  any,

exist, and (b) the acceleration of the maturity of any Senior  Indebtedness
because of a default.

respect to which Section 1102 hereof would be applicable.


Section 1104.     Payment Permitted If No Default.

                  Nothing  contained  in this  Article or elsewhere in this
Indenture or in any of the  Securities  shall  prevent the Company,  at any
time except during the pendency of any dissolution,


                                       59

winding-up,  liquidation or  reorganization  of the Company  referred to in
Section  1102  hereof or under the  conditions  described  in Section  1103
hereof, from making any payments on account of the principal or interest on
the Securities.


Section 1105.     Subrogation to Rights of Holders of Senior
                  Indebtedness.

Indebtedness,  the  rights  of the  Holders  of  the  Securities  shall  be
subrogated  to the rights of the  holders of such  Senior  Indebtedness  to
receive  payments  and  distributions  of  cash,  property  and  securities
applicable to the Senior  Indebtedness  until the principal of and interest
on the Securities shall be paid in full. For purposes of such  subrogation,
no payments or distributions  to the holders of the Senior  Indebtedness of
any cash,  property or securities to which the Holders of the Securities or
the Trustee  would be entitled  except for the  provisions of this Article,
and no payments over  pursuant to the  provisions of this Article to or for
the  benefit  of the  holders  of Senior  Indebtedness  by  Holders  of the
Securities or the Trustee, shall, as among the Company, its creditors other
than holders of Senior  Indebtedness and the Holders of the Securities,  be
deemed to be a payment or  distribution  by the Company to or on account of
the Senior Indebtedness.


Section 1106.     Provisions Solely to Define Relative Rights.

                  The  provisions  of this  Article  are  and are  intended
solely for the purpose of defining  the  relative  rights of the Holders on
the one hand and the  holders  of Senior  Indebtedness  on the other  hand.
Nothing  contained in this Article or elsewhere in this Indenture or in the
Securities  is intended to or shall (a) impair,  as among the Company,  its
creditors other than holders of Senior  Indebtedness and the Holders of the
Securities,   the  obligation  of  the  Company,   which  is  absolute  and
unconditional,  (and which, subject to the rights under this Article of the
holders of Senior Indebtedness,  is intended to rank equally with all other
general obligations of the Company) to pay to the Holders of the Securities
the principal of and interest  (including any  Additional  Interest) on the
Securities  as and when the same shall become due and payable in accordance
with their terms;  or (b) affect the relative rights against the Company of
the Holders of the  Securities  and creditors of the Company other than the
holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture, subject to the rights, if any, under
this  Article  of the  holders  of Senior  Indebtedness  to  receive  cash,
property and securities  otherwise payable or deliverable to the Trustee or
such Holder.

                  Each  Holder  of a  Security  by his  or  her  acceptance
thereof  authorizes  and  directs  the Trustee on his or her behalf to take
such  action  as  may  be  necessary  or   appropriate  to  effectuate  the
subordination  provided  in this  Article  and  appoints  the  Trustee  his
attorney-in-fact for any and all such purposes,  including, in the event of
any dissolution,  winding-up, liquidation or reorganization of the Company,
whether in bankruptcy, insolvency,  receivership proceedings, or otherwise,
the timely filing of a claim for the unpaid balance of the  Indebtedness of
the Company owing to such Holder in the form  required in such  proceedings
and the causing of such claim to be approved.  If the Trustee does not file
a proper claim at least 30 days before the  expiration  of the time to file
such claim,  then the holders of the Senior  Indebtedness and their agents,
trustees or other  representatives are authorized to do so (but,shall in no
event be liable for any  failure to do so) for and on behalf of the Holders
of the Securities.


Section 1108.     No Waiver of Subordination Provisions.

                  No right of any  present  or future  holder of any Senior
Indebtedness to enforce  subordination as herein provided shall at any time
in any way be  prejudiced  or  impaired by any act or failure to act on the
part of the Company or by any act or failure to act, in good faith,  by any
such  holder,  or by any  noncompliance  by the  Company  with  the  terms,
provisions  and  covenants of this  Indenture,  regardless of any knowledge
thereof any such holder may have or be otherwise charged with.

                  Without  in  any  way  limiting  the  generality  of  the
foregoing  paragraph,  the holders of Senior  Indebtedness may, at any time
and from time to time,  without  the consent of or notice to the Trustee or
the Holders of the  Securities,  without  incurring  responsibility  to the
Holders  of  the  Securities   and  without   impairing  or  releasing  the
subordination  provided in this Article or the obligations hereunder of the
Holders of the Securities to the holders of Senior Indebtedness, do any one
or more of the following:  (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter,  Senior  Indebtedness,
or otherwise  amend or supplement in any manner Senior  Indebtedness or any
instrument  evidencing  the  same  or  any  agreement  under  which  Senior
Indebtedness is outstanding;  (ii) permit the Company to borrow,  repay and
then reborrow any or all of the Senior Indebtedness;  (iii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness;  (iv) release any Person liable in any manner
for the  collection  of Senior  Indebtedness;  (v) exercise or refrain from
exercising  any rights  against the Company and any other Person;  and (vi)
apply any sums received by them to Senior Indebtedness.

Section 1109.     Notice to Trustee.

                  The  Company  shall  give  prompt  written  notice to the
Trustee of any fact known to the Company which would prohibit the making of
any  payment  to  or  by  the   Trustee  in  respect  of  the   Securities.
Notwithstanding  the  provisions of this Article or any other  provision of
this  Indenture,  the Trustee  shall not be charged  with  knowledge of the
existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of the Securities, unless and until a Responsible
Officer of the Trustee shall have received  written notice thereof from the
Company, any holder of Senior Indebtedness, any Designated Senior Holder or
any trustee,  fiduciary or agent therefor; and, prior to the receipt of any
such written notice, the Trustee,  subject to the provisions of Section 601
hereof,  shall be  entitled  in all  respects  to assume that no such facts
exist;  provided,  however, that if the Trustee shall not have received the
notice  provided for in this Section at least three  Business Days prior to
the date upon which by the terms  hereof any money may become  payable  for
any purpose (including, without limitation, the payment of the principal of
or  interest on any  Security),  then,  anything  herein  contained  to the
contrary  notwithstanding,  but without limiting the rights and remedies of
the  holders of Senior  Indebtedness  or any  trustee,  fiduciary  or agent
therefor,  the Trustee  shall have full power and authority to receive such
money  and to apply  the same to the  purpose  for  which  such  money  was
received and shall not be affected by any notice to the contrary  which may
be received by it within two Business  Days prior to such date.  Any notice
required  or  permitted  to be given to the  Trustee  by a holder of Senior
Indebtedness  or by any  Designated  Senior  Holder shall be in writing and
shall be sufficient  for every  purpose  hereunder if in writing and either
(i) sent via  facsimile  to the  Trustee,  the  receipt  of which  shall be
confirmed via telephone,  or (ii) mailed,  first class postage prepaid,  or
sent by overnight carrier, to the Trustee addressed to it at the address of
its principal office specified in the first paragraph of this instrument or
at any  other  address  furnished  in  writing  to such  holder  of  Senior
Indebtedness by the Trustee.

                  Subject to the  provisions  of Section  601  hereof,  the
Trustee shall be entitled to rely on the delivery to it of a written notice
by a Person  representing  himself to be a holder of Senior Indebtedness or
Designated  Senior Holder to establish that such notice has been given by a
holder of Senior  Indebtedness  or Designated  Senior Holder.  In the event
that the Trustee determines in good faith that further evidence is required
with respect to the right of any Person as a holder of Senior  Indebtedness
or Designated  Senior Holder to participate in any payment or  distribution
pursuant to this  Article,  the Trustee may request  such Person to furnish
evidence to the reasonable  satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and


                                       62

<PAGE>



any other facts  pertinent to the rights of such Person under this Article,
and if such evidence is not furnished, the Trustee may defer any payment to
such Person pending  judicial  determination as to the right of such Person
to receive such payment.

                  Notwithstanding   anything  else  contained   herein,  no
notice,  request or other  communication  to or with the  Trustee  shall be
deemed  given unless  received by a  Responsible  officer at the  Trustee's
principal corporate trust office.


Section 1110.     Reliance on Judicial Order or Certificate of
                  Liquidating Agent.

                  Upon any payment or distribution of assets of the Company
referred to in this  Article,  the Trustee,  subject to the  provisions  of
Section 601 hereof,  and the Holders of the Securities shall be entitled to
rely  upon  any  order  or  decree   entered  by  any  court  of  competent
jurisdiction  in  which  such  dissolution,   winding-up,   liquidation  or
reorganization  proceedings are pending, or a certificate of the trustee in
bankruptcy,  receiver,  liquidating  trustee,  custodian,  assignee for the
benefit  of  creditors,  agent or  other  Person  making  such  payment  or
distribution, delivered to the Trustee or to the Holders of Securities, for
the purpose of  ascertaining  the Persons  entitled to  participate in such
payment or distribution,  the holders of the Senior  Indebtedness and other
indebtedness  of the Company,  the amount thereof or payable  thereon,  the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.


Section 1111.     Trustee Not Fiduciary for Holders of Senior
                  Indebtedness.

                  The Trustee shall not be deemed to owe any fiduciary duty
to the holders of Senior  Indebtedness  and shall not be liable to any such
holders  if it shall in good  faith pay over or  distribute  to  Holders of
Securities  or to the  Company or to any other  Person  cash,  property  or
securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article or otherwise.


Section 1112.     Rights of Trustee as Holder of Senior
                  Indebtedness; Preservation of Trustee's Rights.

                  The Trustee in its individual  capacity shall be entitled
to all the  rights  set forth in this  Article  with  respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior  Indebtedness,  and nothing in this Indenture  shall
deprive the Trustee of any of its rights as such holder.

                  Nothing  in this  Article  shall  apply to claims  of, or
payments to, the Trustee under or pursuant to Section 607 hereof.


Section 1113.     Article Applicable to Paying Agents.

                  In case at any  time  any  Paying  Agent  other  than the
Trustee  shall  have  been  appointed  by the  Company  and be then  acting
hereunder,  the term  "Trustee" as used in this Article  shall in such case
(unless the context  otherwise  requires)  be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and
purposes as if such Paying  Agent were named in this Article in addition to
or in place of the  Trustee;  provided,  however,  that Section 1111 hereof
shall not apply to the  Company or any  Affiliate  of the  Company if it or
such Affiliate acts as Paying Agent.

Section 1114.     Trust Moneys Not Subordinated.

                  Notwithstanding   anything   contained   herein   to  the
contrary,   payments  from  money  or  the  proceeds  of  U.S.   Government
Obligations held in trust by the Trustee under Article Four for the payment
of the  principal of and interest  (including  Additional  Interest) on the
Securities  shall not be  subordinated  to the prior  payment of any Senior
Indebtedness or subject to the restrictions set forth in this Article,  and
no Holder of Securities  nor the Trustee shall be obligated to pay over any
such  amount  to the  Company,  any  holder  of  Senior  Indebtedness,  any
Designated Senior Holder or any other creditor of the Company.



                              ARTICLE TWELVE

                         REDEMPTION OF SECURITIES


Section 1201.     Mandatory Redemption; Optional Redemption.

                  (a) If COMSAT Capital redeems the Preferred Securities in
accordance  with the terms  thereof,  the  Securities  will  become due and
payable in a principal  amount equal to the  aggregate  stated  liquidation
preference  of the  Preferred  Securities  so redeemed,  together  with any
accrued and unpaid interest thereon, including Additional Interest, if any.
Upon any such event, the Company shall redeem the Securities not later than
the date of  redemption  of the  Preferred  Securities,  and  shall pay the
Redemption  Price  therefor prior to 12:00 noon, New York City time, on the
date of such  redemption  or at such other time on such earlier date as the
Company and COMSAT Capital agree.

                  (b)  The Company shall have the right to redeem the
Securities without premium or penalty, in whole or in part,


                                       64


<PAGE>



concurrent   with  the  redemption  by  COMSAT  Capital  of  the  Preferred
Securities (if any Preferred Securities are then outstanding),  at any time
or from time to time,  on or after July 18,  2000,  at a  redemption  price
equal to 100% of the principal amount to be redeemed,  plus any accrued and
unpaid interest,  including Additional Interest,  if any, to the Redemption
Date.

                  In the event of any redemption in part, the Company shall
not be  required to (i) issue,  register  the  transfer of or exchange  any
Security  during a period  beginning  at the  opening of  business  15 days
before any selection for  redemption of Securities  and ending at the close
of business on the earliest date in which the relevant notice of redemption
is deemed to have been given to all holders of Securities and (ii) register
the transfer of or exchange any Securities so selected for  redemption,  in
whole or in part,  except the unredeemed  portion of any  Securities  being
redeemed in part.


Section 1202.     Applicability of Article.

                  Redemption  of Securities at the election of the Company,
as  permitted by Section  1201(b),  shall be made in  accordance  with such
provision and this Article.


Section 1203.     Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem Securities pursuant
to Section 1201 shall be evidenced  by a Board  Resolution.  In case of any
redemption at the election of the Company,  the Company shall,  at least 30
days and no more than 60 days  prior to the  Redemption  Date  fixed by the
Company,  notify the Trustee of such  Redemption  Date and of the principal
amount of  Securities  to be  redeemed  and provide a copy of the notice of
redemption  given to Holders  of  Securities  to be  redeemed  pursuant  to
Section 1204.


Section 1204.     Notice of Redemption.

                  Notice of redemption shall be given by first-class  mail,
postage prepaid, mailed not less than 30 nor more than 60 days prior to the
Redemption  Date,  to each  Holder of  Securities  to be  redeemed,  at his
address appearing in the Security Register.

                  All notices of redemption  shall be irrevocable and shall
state:

                  (1)        the Redemption Date,

                  (2)        the Redemption Price,



                                       65


<PAGE>



                  (3) that on the Redemption Date the Redemption Price will
become due and payable  upon each such  Security  to be  redeemed  and that
interest thereon will cease to accrue on and after said date, and

                  (4)        the place or places where such Securities are to
be surrendered for payment of the Redemption Price.

                  Notice of  redemption of Securities to be redeemed at the
election of the Company  shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.


Section 1205.     Deposit of Redemption Price.

                  Prior to any  Redemption  Date, the Company shall deposit
with the  Trustee or with a Paying  Agent (or,  if the Company is acting as
its own Paying  Agent,  segregate  and hold in trust as provided in Section
1003) an amount of money  sufficient  to pay the  Redemption  Price of, and
(except if the Redemption  Date shall be an Interest  Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.


Section 1206.     Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid,  the
Securities so to be redeemed shall, on the Redemption Date,  become due and
payable at the Redemption Price therein specified,  and from and after such
date,  unless the Company  shall  default in the payment of the  Redemption
Price and accrued  interest,  such Securities shall cease to bear interest.
Upon surrender of any such Security for redemption in accordance  with said
notice, such Security shall be paid by the Company at the Redemption Price,
together with accrued interest to the Redemption Date;  provided,  however,
that  installments  of interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities,  or one
or more Predecessor Securities, registered as such at the close of business
on the relevant record dates according to their terms and the provisions of
Section 307.




                                       66


<PAGE>



                  If any  Security  called for  redemption  shall not be so
paid upon surrender  thereof for  redemption,  the principal  shall,  until
paid,  bear  interest  from the  Redemption  Date at the rate  borne by the
Security.

such  amount  to  Seller  out of  proceeds  from  fees  paid  to the NHL by

its share of such fees, the amount of U.S.$2,000,000 per expansion team, up
to a maximum of U.S.$8,000,000, out of which the NHL shall reimburse Seller
$1,000,000  per  expansion  team,  except  that  during the first two years
following  the  Closing,  Buyer  shall  receive  its  entire  share of such

          Buyer  hereby  represents  and warrants to Seller as set forth in

delivered  will  constitute,  a valid  and  binding  obligation  of  Seller
enforceable against Buyer in accordance with their respective terms.

          5.3 Regulatory Approvals.  No authorization,  consent or approval
of or notification to any United States federal, state or local public body

          5.4 No  Conflict or  Violation.  If the  Shareholder  Approval is
obtained,  neither the  execution  and delivery of this  Agreement  and the
Ancillary  Agreements,  nor  consummation  by  Buyer  of  the  transactions
contemplated hereby and thereby,  nor compliance with any of the provisions
hereof or  thereof  will  conflict  with or result in a  violation  of: (i)

<PAGE>


                                  - 16 -

          any and all  data and  information  primarily  pertaining  to the

warranties set forth in Article 4. In connection  with such access,  Seller
shall  permit Buyer to discuss the affairs of the  Acquisition  Assets with
designated employees,  officers and directors of Seller; provided, however,
that  no  investigation  pursuant  to  this  Section  6.1 or  otherwise  in
connection  with this  Agreement or the  transactions  contemplated  hereby
shall  diminish or modify the scope of, or in any manner  whatsoever  alter
the effect of, any representation,  certification, warranty, obligation, or
agreement of the Seller set forth in this Agreement.

          6.2  Conduct of  Business.  Except for  actions  contemplated  or
required to be taken pursuant to this  Agreement,  Seller shall conduct its
hockey  operations  from  the  date  hereof  through  the  Closing  Date in
accordance with prior practice and in the ordinary course of business,  and
without  limiting the generality of the  foregoing,  Seller shall not, with
respect to the Acquisition Assets, except with the prior written consent of
Buyer:  (i)  enter  into any  transaction  not in the  ordinary  course  of
business;  (ii) purchase,  sell or dispose of any of the Acquisition Assets
(including,  without  limitation,  any of  the  Assumed  Contracts);  (iii)
mortgage,  pledge  or  encumber  any  of  the  Acquisition  Assets,  unless
discharged  before  Closing;  (iv) amend,  modify,  renew or terminate  any
Assumed  Contract,  other  than in the  ordinary  course  of  business  and
consistent with past practice, or relinquish, forfeit or waive any right or
increase  any  obligation  under any  Assumed  Contract,  other than in the
ordinary course of business; (v) make any increase in, or any commitment to
increase, the compensation payable to any of Seller's players or employees;
(vi) materially alter the manner of keeping its books, accounts or records;
or (vii)  propose,  authorize  or  commit,  arrange  or agree in writing or
otherwise to take, any of the foregoing actions.

          6.3 Preservation of Organization and  Relationships.  Seller will
use its  reasonable  efforts to  preserve  intact the  business  of the AHL
Franchise and to continue  operation of the AHL Franchise  substantially in
accordance  with prior  practice  and will use its best efforts to preserve
for Buyer its existing  relationships with suppliers,  customers and others
having business  relations with the AHL Franchise.  Seller will not do, and
will use its best  efforts  not to permit to be done,  any act which  would
cause the  representations  and  warranties of Seller  contained  herein to
become untrue or inaccurate.

          6.4 Consents;  Assumed  Contracts.  (i) Buyer and Seller will use
their  respective  best efforts to obtain prior to the Closing Date any and

<PAGE>


                                  - 17 -

          to the assignment of the Assumed Contracts;  and (b) the consents
of the NHL and the AHL to the transfers of the franchises. Buyer and Seller
shall  commence  the process of  obtaining  the consents of the NHL and AHL
within five  business days of signing this  Agreement,  and Buyer agrees to
cooperate  to  the  fullest  extent  necessary  to  obtain  such  consents,
including,  without  limitation to comply with all reasonable  requirements
contained  in such  consents  and to  provide  any and  all  operating  and
financial information reasonably required in connection with such consents.

          (ii) Buyer and Seller  will give any notices to, make any filings
with, and use their  respective best efforts to obtain any  authorizations,
consents and  approvals of United States or Canadian  federal,  provincial,
state and local  governmental  agencies and  authorities  necessary for the
consummation of the transactions contemplated hereby.

          (iii) Notwithstanding any other provisions of this Agreement, the
parties  agree  that  the  consent  of the AHL to the  transfer  of the AHL
Franchise  and the consent of the City of Cornwall  for the transfer of the
lease with the City of Cornwall to Buyer are not  essential  conditions  to
this  Agreement  and the  Parties  agree  to  consummate  the  transactions
contemplated by this Agreement  (other than those related to such consents)
without diminution in the Purchase Price and without indemnification of the
Buyer by the Seller if those  consents are not obtained.  In the event that
Seller is unable to obtain the consent to transfer of the AHL  Franchise or
of the City of Cornwall within one year following the Closing Date,  Seller
may then elect to sell the AHL Franchise to any other party with respect to
whom the necessary consents may be obtained;  provided,  however,  that the
proceeds of such sale, if any, shall be remitted to Buyer  immediately upon
receipt by Seller.

          6.5 Notice of  Breaches.  Promptly  after  becoming  aware of any
event  and  promptly  after  receiving  any  notice  which  would  cause or
constitute  a  material  breach of any of the  covenants  set forth in this
Article 6 or any of the representations and warranties set forth in Article
4, Seller will inform  Buyer of such event and will send to Buyer a copy of
such notice, and will use its best efforts promptly to remedy or to prevent
the  occurrence of such breach.  If Buyer does not terminate this Agreement
pursuant  to Section  13.1 within 10  business  days after  receipt of such
written  notice,  such  written  notice will be deemed to have  amended the
relevant  disclosure  statements set forth in the Disclosure  Schedule,  to
have qualified the representations  and warranties  contained in Article 4,
and to  have  cured  any  misrepresentation  or  breach  of  warranty  that
otherwise  might have existed  hereunder by reason of the subject matter of
such notice.

          6.6 Limitation on Solicitation.  Until the Closing Date,  neither
Seller, nor any of its officers, directors, employees,


<PAGE>


                                  - 18 -

          representatives,   agents  or  affiliates,   shall,  directly  or
indirectly,  recommend, propose, solicit, initiate or promote (or authorize
any person or entity to recommend,  propose,  solicit, initiate or promote)
any inquiry,  proposal or offer from,  or provide any  information  to, any
corporation,  partnership,  person or other entity or group (other than the
Buyer  and its  affiliates,  representatives  and  agents)  concerning  any
purchase or sale of material assets, merger, reorganization, consolidation,
business  combination  or similar  transaction  involving  the  Acquisition
Assets (collectively "Solicitation").

          6.7  Further  Assurances.   Buyer  and  Seller  shall  use  their
respective  best efforts to take,  or cause to be taken,  all action and to
do, or cause to be done, all things  necessary,  proper or advisable  under
applicable  laws  and  regulations  expeditiously  to  consummate  and make
effective the transactions contemplated by this Agreement.

          11.1 Equitable Relief.  Buyer's obligations  contained in Section

or remedies which they may possess,  they shall respectively be entitled to
injunctive  and  other  equitable  relief  in the form of  preliminary  and
permanent  injunctions  without bond or other  security in the event of any

shall, and shall cause its employees, attorneys,  accountants, advisors and
other  representatives to, keep confidential and not disclose to any person

          (e) the discloser expressly consents thereto in writing.

          (iii) If the transactions  contemplated by this Agreement are not
consummated,  then upon the request of either party, the other party shall,
promptly  return or destroy (at the election of the  responding  party) any
written  materials  that it has  received  from  the  requesting  party  in
connection  with this Agreement or the  transactions  contemplated  hereby,
together with any copies of such materials made by it, and promptly destroy
any analyses, studies or other documents prepared by such other party

                                  - 23 -

with  respect  to,  or  based  upon,   such  materials  or  other
Confidential  Information  received from the  requesting  party,  and shall
promptly furnish the requesting party an officer's  certificate  confirming
that such actions have been taken.

          (iv) For purposes of this Agreement,  "Confidential  Information"
shall mean any and all  information  (excluding  information  in the public
domain,  except as a result of a breach by a party of this  confidentiality
obligation)  relating to the parties which is confidential,  proprietary or
otherwise  not  generally  available  to the public but shall  specifically
exclude the negotiation process resulting in this Agreement, this Agreement
and any and all information related to the operation of Seller in Quebec.

          11.4 Bulk Sales Laws.  Seller and Buyer hereby  waive  compliance
with the bulk  transfer  law or statute  of the  Province  of Quebec  which
requires  notice to or provides  for the rights of  creditors  of Seller in
connection  with the sale of the  assets of Seller  to Buyer.  Such  waiver
shall not be  deemed to waive  Buyer's  rights to  indemnification  against
liabilities of Seller that are not Assumed Obligations  pursuant to Section
12.2(i).

                                ARTICLE 12

                 SURVIVAL OF REPRESENTATIONS, WARRANTIES,
                 COVENANTS AND AGREEMENTS; INDEMNIFICATION

          12.1  Survival  of  Representations,  Warranties,  Covenants  and
Agreements.  The  representations,  warranties,  covenants  and  agreements
contained  herein or in any exhibit,  schedule,  document,  certificate  or
other  instrument  delivered  pursuant to this Agreement  shall survive the
Closing and expire at 11:59 p.m. on the second  anniversary  of the Closing
Date (the "Expiration  Date").  From and after the Expiration Date, none of
Seller or Buyer or any  affiliate  of  Seller  or Buyer  shall be under any
liability whatsoever with respect to any representation or warranty, except
for claims,  the existence of which any party shall have notified the other
party in writing  prior to the  Expiration  Date in the manner  provided in
Section 12.2.

          12.2  Indemnification.  (i) By Seller. From and after the Closing
Date,  Seller  shall  indemnify,  save and  hold  harmless  Buyer,  and its
employees,  representatives,  officers,  directors  and  agents,  from  and
against  any  and  all  actions,  suits,  claims,   proceedings,   demands,
assessments  and  judgments,  costs,  losses,  liabilities,   damages,  and
expenses  (including,  without limitation,  settlement costs and reasonable
out-of-pocket  legal or other expenses for  investigating  or defending any
actions or threatened actions) in connection with, relating to or resulting
from:


<PAGE>


                                  - 24 -

(a)  any  breach  of  any   representation  or  warranty  or  the
inaccuracy of any  representation  made by Seller in this  Agreement or any
certificates  delivered  pursuant to this Agreement;  (b) any breach of any
covenant  or  agreement  of or  made  by  Seller  in or  pursuant  to  this
Agreement; (c) any Excluded Liability; or (d) if applicable, any failure to
comply  with the "bulk  sales"  requirements  of the  Province  of  Quebec.
Notwithstanding  the foregoing,  Seller shall not be obligated to indemnify
Buyer under this  Agreement (A) for those Adverse Claims that are otherwise
indemnifiable  and which are: (1)  disclosed to Buyer in this  Agreement or
the  Disclosure  Schedule  or any  Exhibit  hereto,  (2)  accepted by Buyer
according to Section 6.5, or (3) Assumed  Obligations  and (B) unless Buyer
seeks such indemnification in good faith and on a reasonable basis.

          (ii) By Buyer. From and after the Closing,  Buyer shall indemnify
and  save  and  hold  harmless  Seller,   and  its  respective   employees,
representatives,  officers,  directors and agents, from and against any and
all  actions,  suits,  claims,   proceedings,   demands,   assessments  and
judgments,  costs,  losses,  liabilities,  damages and expenses (including,
without limitation,  settlement costs and reasonable out-of-pocket legal or
other  expenses for  investigating  or defending  any actions or threatened
actions) in connection with,  relating to or resulting from: (a) any breach
of any  representation or warranty or the inaccuracy of any  representation
made by Buyer in this Agreement or any certificates  delivered  pursuant to
this  Agreement;  (b) any breach of any covenant or agreement of or made by
Buyer in or pursuant  to this  Agreement;  or (c) any Assumed  Obligations.
Notwithstanding  the  foregoing  Buyer shall not be  obligated to indemnify
Seller  under  this   Agreement  (A)  for  any  actions,   suits,   claims,
proceedings,  demands,  assessments or enforcement  actions  against Seller
that are otherwise indemnifiable and which are Excluded Liabilities and (B)
unless Seller seeks such  indemnification in good faith and on a reasonable
basis.

          (iii) Defense of Claims. If any action, suit, claim,  proceeding,
demand, assessment or enforcement action (collectively,  "Claims") is filed
against  any party  entitled  to the benefit of  indemnity  hereunder,  the
indemnified  party shall give written  notice  thereof to the  indemnifying
party as promptly as practicable (and in any event within fifteen (15) days
after the service of the citation or summons);  provided, however, that the
failure of any indemnified party to give timely notice shall not affect the
rights to  indemnification  hereunder  except  and to the  extent  that the
indemnifying party demonstrates actual damage caused by such failure. After
such  notice,  if the  indemnifying  party  acknowledges  in writing to the
indemnified  party that it is obligated under the terms of its indemnity in
this Agreement, the indemnifying party, shall be entitled, if it so elects,
(a) to take control of the defense and  investigation of such Claim, (b) to
employ and engage  attorneys of its own choice,  subject to approval by the
indemnified  party,  which approval shall not be  unreasonably  withheld to
defend


<PAGE>


                                  - 25 -

the same, at the indemnifying party's cost, risk and expense, and
(c) to  compromise  or settle such claim,  which  compromise  or settlement
shall be made only with the written consent of the indemnified  party, such
consent  not to be  unreasonably  withheld.  The  indemnified  party  shall
cooperate in all reasonable  respects with the  indemnifying  party and its
attorneys in the  investigation,  trial and defense of such Claim,  and any
appeal arising  therefrom;  provided,  however,  that the indemnified party
may, at its own cost, participate in such investigation,  trial and defense
of such Claim, and any appeal arising therefrom; and provided further, that
the  indemnifying  party shall have an obligation  to keep the  indemnified
party  reasonably  apprised  of the  status of the Claim,  to  furnish  the
indemnified  party with all documents and information  that the indemnified
party shall reasonably request in connection therewith, and to consult with
the  indemnified  party prior to acting on major  matters  involved in such
Claim, including settlement discussions.

          (iv) Limitations. Neither Buyer nor Seller shall be liable to the
other under this section 12.2 until the aggregate  amount otherwise due the
party being indemnified exceeds U.S. $500,000;  then the indemnifying party
shall be  obligated to pay such  indemnification  but only for what exceeds
U.S. $500,000; provided, however, that this limitation shall not apply with
respect to (a) indemnification  arising out of a breach of a representation
or  warranty  contained  in  Sections  4.11 or 4.15,  (b) any Claims by any
contracting  party other than under an Assumed  Contract for the provisions
of goods or services to the Seller in the Province of Quebec, (c) any claim
by  a  creditor  based  upon  failure  to  comply  with  the  "bulk  sales"
requirements  of the Province of Quebec and (d) any Claim  challenging  the
consummation  of the  transaction  contemplated  by this Agreement by or on
behalf of Gilles Leger or any federal,  provincial  or local  government or
governmental agency.

          12.3  Letter of  Guarantee.  Buyer and Seller  shall enter into a
Guarantee  Indemnification  Agreement  substantially in the form of Exhibit
12.3  attached  hereto  under  which  Buyer  will  provide  Seller  with an
irrevocable letter of guarantee for an amount of US$2,000,000.  The parties
agree and acknowledge that the irrevocable letter of guarantee shall not be
Buyer's exclusive method of receiving  indemnification from Seller pursuant
to this Article 12 or otherwise.

                                ARTICLE 13

                         TERMINATION OF AGREEMENT

          13.1  Termination  Events.  Subject to the  provisions of Section
13.2, this Agreement may, by written notice given at or


<PAGE>


                                  - 26 -

prior to the  Closing  in the  manner  hereinafter  provided,  be
terminated and abandoned prior to the Closing:

          (i) By Buyer or Seller if the other party materially  defaults or
breaches  with  respect  to the due and  timely  performance  of any of its
covenants,  agreements and obligations  contained herein,  and such default
cannot  within a reasonable  time period be cured (or after notice  thereof
and an  opportunity  of 15 calendar days  thereafter to cure,  has not been
cured) and has not been waived;

          (ii) by mutual written consent of Buyer and Seller;

          (iii) by either  Buyer or Seller  if the  Closing  shall not have
occurred  on or before July 15,  1995,  or such later date as may be agreed
upon by the parties; or

          (iv) by Buyer in the event that the  transfer  fee imposed by the
NHL in connection with granting its consent to the transfer to Buyer of the
NHL  Franchise  and moving  the NHL  Franchise  to Denver is  greater  than
U.S.$8,000,000, payable on the terms set forth in Section 1.3(ii).

          13.2  Effect of  Termination.  In the  event  this  Agreement  is
terminated  pursuant to Section 13.1, such termination shall be without any
liability  or  obligation  by  the   terminating   party  and  all  further
obligations  of the  parties  hereunder  shall  terminate,  except that the
obligations  set forth in Sections 7.1, 11.3 and 14.13 hereof shall survive
such termination and Buyer agrees not to bring any action or make any claim
against  Seller if Seller  terminates  pursuant to Section  13.1(iii)  as a
result of a failure of any conditions  contained in Section 8 or Section 10
hereof.  Notwithstanding the foregoing,  if this Agreement is terminated by
Buyer as a result  of  Seller's  failure  to  consummate  the  transactions
contemplated  hereby as a result of Seller's  voluntary  decision to retain
the NHL  Franchise  in Quebec or sell the NHL  Franchise to any other party
then Seller shall pay to Buyer U.S.$4,000,000 within 20 business days after
such termination which will liquidate all damages.
