ITEM 5 OTHER EVENTS

     On October 7, 1997,  Orion Network  Systems,  Inc. (the  "Company"),  Loral
Space &  Communications  Ltd.  ("Acquiror") and Loral Satellite  Corporation,  a
wholly owned  subsidiary of Acquiror  ("Merger Sub"),  entered into an Agreement
and Plan of Merger (the "Merger  Agreement"),  pursuant to which Merger Sub will
merge with and into the  Corporation,  with the Corporation  being the surviving
corporation  and thereby  becoming a wholly owned  subsidiary  of Acquiror  (the
"Merger").

     The Merger  Agreement  provides  that (i) each share of common  stock,  par
value  $.01 per  share,  of the  Company  ("Company  Common  Stock"),  excluding
treasury  shares  and  shares  owned by  Acquiror  or it  subsidiaries,  will be
converted  into and  exchanged for the right to receive the number of fully paid
and nonassessable  shares of common stock, par value $.01 per share, of Acquiror
("Acquiror Common Stock") equal to the Exchange Ratio (as described below), (ii)
each  share of  preferred  stock,  par  value  $.01 per  share,  of the  Company
("Company  Preferred  Stock") will be converted into and exchanged for the right
to receive the number of fully paid and nonassessable  shares of Acquiror Common
Stock equal to the Exchange Ratio  multiplied by the number of shares of Company
Common Stock into which such share of Company  Preferred  Stock was  convertible
immediately  prior to the Effective Time of the Merger,  (iii) each  outstanding
stock option to purchase  shares of Company  Common Stock will be converted into
an option to acquire the number of shares of Acquiror  Common Stock equal to the
Exchange  Ratio  multiplied by the number of shares of Company  Common Stock for
which such option was exercisable, and (iv) each outstanding warrant to purchase
shares of Company  Common Stock will be converted  into a warrant to acquire the
number of shares of Acquiror Common Stock equal to the Exchange Ratio multiplied
by the  number of shares of Company  Common  Stock for which  such  warrant  was
exercisable.

     Pursuant  to the  terms of the  Merger  Agreement,  the  Exchange  Ratio is
determined as follows:

     (i) if the  average  of  the  volume-weighted  average  trading  prices  of
Acquiror Common Stock for the twenty  consecutive  trading days on which trading
of Acquiror Common Stock occurs ending the tenth trading day  immediately  prior
to the closing date for Merger (the "Determination  Price") is less than $24.458
but  greater  than  $16.305,  the  Exchange  Ratio is the  quotient  obtained by
dividing $17.50 by the Determination Price,

     (ii) if the  Determination  Price is equal to or greater than $24.458,  the
Exchange Ratio is 0.71553 and

     (iii) if the  Determination  Price is equal to or less  than  $16.305,  the
Exchange Ratio is 1.07329.

     The Merger is subject to a number of conditions,  including approval by the
Company's  stockholders,  approval by the Federal Communications  Commission



<PAGE>



and other  regulatory  approvals.  Although not a condition  of the Merger,  the
Company intends to seek an Internal Revenue Service ruling as to eligibility for
a tax-free exchange.

     In connection with the Merger Agreement,  certain principal stockholders of
the Company and members of the Company's management have agreed to vote in favor
of the  Merger and have  granted to the  Acquiror  the right to  purchase  their
securities  in the Company for a price equal to the Merger  consideration  under
certain  circumstances.  The Company expects the Merger to be consummated by the
first quarter of 1998.

     The  foregoing   descriptions   of  the  Merger   Agreement  and  Principal
Stockholder  Agreement do not purport to be complete and are  qualified in their
entirety  by the terms and  conditions  of the Merger  Agreement  and  Principal
Stockholder  Agreement,  which are filed as Exhibits 2.1 and 2.2,  respectively,
and are incorporated herein by reference. A copy of the press release announcing
the  execution  of the Merger  Agreement  is  attached  as  Exhibit  99.1 and is

                          AGREEMENT AND PLAN OF MERGER

          THIS AGREEMENT AND PLAN OF MERGER (this  "Agreement")  is entered into
this 7th day of October,  1997,  by and among ORION  NETWORK  SYSTEMS,  INC.,  a
Delaware corporation  ("Company"),  LORAL SPACE & COMMUNICATIONS LTD., a Bermuda
company ("Acquiror"),  and LORAL SATELLITE  CORPORATION,  a Delaware corporation
("Merger Sub").

          WHEREAS,  the Boards of Directors of the Company,  Acquiror and Merger
Sub have each determined that it is fair to, and in the best interests of, their
respective  stockholders that Merger Sub, a wholly-owned subsidiary of Acquiror,
be merged  with and into the  Company,  pursuant to and subject to the terms and
conditions of this Agreement and the Delaware General Corporation Law ("Delaware
Law"); and

          WHEREAS,  concurrently  with the execution of this Agreement and as an
inducement to Acquiror to enter into this Agreement,  certain  stockholders have
entered into an agreement with Acquiror (the "Principal Stockholder  Agreement")
pursuant to which,  among other things,  such  stockholders  have agreed to vote
their shares of stock of the Company in favor of this Agreement,  the Merger (as
defined below) and the other transactions contemplated by this Agreement; and

          NOW,  THEREFORE,  in consideration of the foregoing and the respective
representations,   warranties,  covenants  and  agreements  set  forth  in  this
Agreement, the parties hereto agree as follows:

                                   ARTICLE I.

                                   THE MERGER

          Upon  the  terms  and  subject  to the  conditions  set  forth in this
Agreement,  and in  accordance  with  Delaware  Law, at the  Effective  Time (as
defined in Section  1.2)  Merger Sub shall be merged  with and into the  Company
(the "Merger").  As a result of the Merger, the separate corporate  existence of
Merger  Sub  shall  cease  and  the  Company  shall  continue  as the  surviving
corporation  of the  Merger  (sometimes  referred  to herein  as the  "Surviving
Corporation")  and a  wholly-owned  subsidiary  of  Acquiror.  The  name  of the
Surviving Corporation shall be Loral Orion Network Systems, Inc.

     SECTION 1.2.     EFFECTIVE TIME.

          As promptly as  practicable on the Closing Date (as defined in Section
1.6),  the parties  hereto shall cause the Merger to be  consummated by filing a
certificate of merger (the  "Certificate of Merger") with the Secretary of State
of the



                                       1
<PAGE>


State of Delaware,  in such form as required by, and executed in accordance with
the  relevant  provisions  of,  Delaware Law and in such form as approved by the
Company  and  Acquiror  prior to such  filing  (the  time of the  filing  of the
Certificate of Merger or the time specified therein being the "Effective Time").

     SECTION 1.3.     EFFECT OF THE MERGER.

          At the Effective  Time,  the effect of the Merger shall be as provided
in the applicable provisions of Delaware Law. Without limiting the generality of
the foregoing,  and subject thereto,  at the Effective Time, except as otherwise
provided herein, all the rights, privileges, powers and franchises of Merger Sub
and  the  Company  shall  vest in the  Surviving  Corporation,  and  all  debts,
liabilities  and duties of Merger Sub and the  Company  shall  become the debts,
liabilities and duties of the Surviving Corporation.

     SECTION 1.4.     CERTIFICATE OF INCORPORATION; BYLAWS.

          At the Effective Time, (a) the certificate of  incorporation of Merger
Sub, as, in effect immediately prior to the Effective Time and as amended by the
Certificate  of  Merger,  shall  be  the  certificate  of  incorporation  of the
Surviving  Corporation,  and  (b)  the  bylaws  of  Merger  Sub,  as  in  effect
immediately  prior to the Effective  Time,  shall be the bylaws of the Surviving
Corporation.

     SECTION 1.5.     DIRECTORS AND OFFICERS.

          The directors of Merger Sub (or such other or  additional  individuals
as Acquiror may designate  prior to Closing)  shall be the initial  directors of
the  Surviving  Corporation,   each  to  hold  office  in  accordance  with  the
certificate of incorporation  and bylaws of the Surviving  Corporation;  and the
officers of Merger Sub (or such other or additional  individuals as Acquiror may
designate prior to Closing) shall be the officers of the Surviving  Corporation,
in each case until their respective successors are duly elected or appointed and
qualified.

     SECTION 1.6.     CLOSING.

          Subject to the terms and conditions of this Agreement,  the closing of
the Merger (the  "Closing")  will take place as promptly  as  practicable  after
satisfaction of the latest to occur or, if permissible, waiver of the conditions
set forth in Article VIII hereof (the "Closing Date"), at the offices of Willkie
Farr & Gallagher,  One Citicorp Center, 153 East 53rd East Street, New York, New
York 10022,  unless another date or place is agreed to in writing by the parties
hereto.

     SECTION 1.7.     SUBSEQUENT ACTIONS.

          If, at any time after the Effective  Time,  the Surviving  Corporation
shall  consider  or be  advised  that any  deeds,  bills  of sale,  assignments,
assurances or 



                                       2
<PAGE>


any other  actions or things are  necessary  or  desirable to continue in, vest,
perfect or confirm  of record or  otherwise  in the  Surviving  Corporation  its
right,  title  or  interest  in,  to or  under  any of the  rights,  properties,
privileges,  franchises  or assets of  either  of its  constituent  corporations
acquired or to be acquired by the  Surviving  Corporation  as a result of, or in
connection  with,  the  Merger or  otherwise  to carry out this  Agreement,  the

authorized  to execute and deliver,  in the name and on behalf of either of such
constituent  corporations,  all  such  deeds,  bills of  sale,  assignments  and
assurances  and to take  and  do,  in the  name  and on  behalf  of each of such
corporations or otherwise, all such other actions and things as may be necessary
or desirable to vest,  perfect or confirm any and all right,  title and interest
in, to and under such rights,  properties,  privileges,  franchises or assets in
the Surviving Corporation or otherwise to carry out this Agreement.

                                   ARTICLE II.

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

     SECTION 2.1.     CONVERSION OF SECURITIES.

          At the Effective  Time, by virtue of the Merger and without any action
on the part of  Acquiror,  Merger Sub,  the Company or the holders of any of the
following securities:

          (a)  Common  Stock.  Each  share of common  stock,  par value $.01 per
share,  of the Company  ("Common  Stock")  (excluding  any shares  described  in
Sections  2.1(c)  and  (d))  issued  and  outstanding  immediately  prior to the
Effective  Time shall cease to be  outstanding  and shall be converted  into and
exchanged  for the right to receive  the number of fully paid and  nonassessable
shares of common  stock,  par value  $0.01 per  share,  of  Acquiror  ("Acquiror
Shares") equal to the Exchange  Ratio defined  below.  All such shares of Common
Stock shall cease to be  outstanding  and shall  automatically  be canceled  and
retired and shall cease to exist, and each certificate previously evidencing any
such  shares  shall  thereafter  represent  only the right to receive the Merger
Consideration  as  described  below.  The  holders  of  certificates  previously
evidencing  such shares of Common  Stock  outstanding  immediately  prior to the
Effective  Time shall  cease to have any rights  with  respect to such shares of
Common  Stock,  except  as  otherwise  provided  herein  or by  law.  Each  such
certificate previously evidencing such shares of Common Stock shall be exchanged
for the number of shares previously  evidenced by the canceled  certificate upon
the surrender of such  certificate in accordance  with the provisions of Section
2.2, multiplied by the Exchange Ratio.

          The Exchange Ratio shall be as follows:


                                       3
<PAGE>


          (i) if the Determination  Price shall be less than $24.458 but greater
          than  $16.305,  the Exchange  Ratio shall be the quotient  obtained by
          dividing $17.50 by the Determination Price,

          (ii) if the  Determination  Price  shall be equal to or  greater  than
          $24.458, the Exchange Ratio shall be 0.71553 and

          (iii) if the  Determination  Price  shall  be  equal  to or less  than
          $16.305, the Exchange Ratio shall be 1.07329.

          "Determination  Price"  shall mean the average of the  Volume-Weighted
Average  Trading  Prices of  Acquiror  Shares  for the twenty  (20)  consecutive
trading days on which trading of Acquiror  Shares occurs (each a "Trading  Day")
(the "Averaging  Period")  ending on the tenth trading day immediately  prior to
the Closing Date for the Merger,  rounded to the nearest one-hundred  thousandth
(or if there shall not be a nearest one-hundred  thousandth,  to the next higher
one-hundred thousandth).  "Volume-Weighted Average Trading Price" means, for any
Trading  Day,  an amount  equal to (i) the  cumulative  sum,  for each  trade of
Acquiror  Shares  during such Trading Day on the New York Stock  Exchange,  Inc.
(the  "NYSE")  (or,  if such  security  is not  listed on the NYSE,  such  other
principal exchange or over-the-counter market on which such security is listed),
of the product  of: (x) the sale price  times (y) the number of Acquiror  Shares
sold at such  price,  divided  by (ii) the total  number of  Acquiror  Shares so
traded during the Trading Day.

          (b) Company  Preferred Stock.  Subject to the other provisions of this
Section 2.1,  each share of preferred  stock,  par value $.01 per share,  of the
Company  ("Preferred  Stock"),  issued and outstanding  immediately prior to the
Effective  Time  (excluding  any shares  described in Sections  2.1(c) and (d)),
shall be  converted  into the right to  receive  the  number  of fully  paid and
nonassessable  Acquiror  Shares equal to the Exchange  Ratio  multiplied  by the
number of shares of Common  Stock into which such share of  Preferred  Stock was
convertible  immediately  prior to the Effective Time. The Company's Series A 8%
Cumulative Redeemable Preferred Stock ("Series A Preferred Stock"),  Series B 8%
Cumulative  Redeemable Preferred Stock ("Series B Preferred Stock") and Series C
6% Cumulative Redeemable Preferred Stock ("Series C Preferred Stock"),  shall be
referred to herein  collectively  as the  "Preferred  Stock." The Exchange Ratio
multiplied by the number of Acquiror Shares into which a share of each series of
the Company's Preferred Stock shall be converted in the Merger shall be referred
to herein  collectively  as the "Per Share Amounts" and  individually  as a "Per
Share Amount." The Common Stock and Preferred  Stock shall be referred to herein
collectively as the "Capital Stock."

          All such shares of Preferred  Stock shall cease to be outstanding  and
shall  automatically  be canceled and retired and shall cease to exist, and each
certificate  previously  evidencing any such shares shall  thereafter  represent
only the 


                                       4
<PAGE>

right to receive the Merger  Consideration  as described  below.  The holders of
certificates  previously  evidencing such shares of Preferred Stock  outstanding
immediately  prior to the  Effective  Time shall  cease to have any rights  with
respect to such shares of Preferred Stock,  except as otherwise  provided herein
or by law. Each such certificate  previously evidencing such shares of Preferred
Stock shall be exchanged for the applicable  Per Share Amount  multiplied by the
number of shares  previously  evidenced  by the  canceled  certificate  upon the
surrender of such  certificate in accordance with the provisions of Section 2.3,
without interest.

          (c) Acquiror-Owned  Shares. All shares of capital stock of the Company
owned,  directly or  indirectly,  by Acquiror,  Merger Sub or any other Acquiror
Subsidiary  (as  defined in  Section  5.1) shall be  canceled  and  extinguished
without any  conversion  thereof and no amount shall be delivered or deliverable
in exchange therefor;

          (d) Treasury Stock. All shares of capital stock of the Company held in
the treasury of the Company  immediately  prior to the  Effective  Time shall be
canceled and extinguished  without any conversion thereof and no amount shall be
delivered or deliverable in exchange therefor;

          (e) Merger Sub Stock.  Each share of common stock,  par value $.01 per
share, of Merger Sub issued and outstanding  immediately  prior to the Effective
Time shall be converted into and exchanged for one (1) duly and validly  issued,
fully paid and nonassessable share of common stock of the Surviving Corporation;
and

          (f) No Fractional  Shares.  No  certificate  or scrip  representing  a
fractional  share of Acquiror  Shares  shall be issued  pursuant to this Section
2.1, and such  fractional  interests  shall not entitle the owner thereof to any
rights as a security  holder of  Acquiror.  All  holders  entitled  to receive a
fractional  share of Acquiror  Shares  shall be  entitled  to  receive,  in lieu
thereof,  cash (without  interest) in an amount equal to the product of (i) such
fractional part of Acquiror  Shares  multiplied by (ii) the last sales price per
Acquiror  Share on the NYSE  Composite  Transactions  reporting  system  for the
Closing Date. As promptly as possible after the  determination  of the amount of
cash, if any, to be paid to holders of fractional interests,  the Exchange Agent
shall so notify Acquiror,  and Acquiror shall cause the Surviving Corporation to
deposit such amount with the Exchange  Agent and shall cause the Exchange  Agent
to forward  payments to such holders of fractional  interests  subject to and in
accordance with the terms hereof.

          (g)  Interest  and  Dividend  Shares.  To the extent that any interest
accrued or  payable  with  respect to the  Company's  8.75%  Convertible  Junior
Subordinated  Debentures  due 2012 or any  dividends  accrued  or  payable  with
respect to the Series C Preferred  Stock,  in each case which are payable in the
form of Common Stock,  have not been paid as of the Closing Date,  such interest
and dividends  shall be converted  into the right to receive the number of fully
paid and


                                       5
<PAGE>

nonassessable  Acquiror  Shares equal to the Exchange  Ratio  multiplied  by the
number of shares of Common Stock that would have been issued if such interest or
dividends  had been  paid  immediately  prior to the  Effective  Time or, to the
extent such  interest or  dividends  cannot be so  converted  under the terms of
their governing instruments, such interest and dividends shall be paid in Common
Stock immediately prior to the Effective Time and converted  pursuant to Section
2.1(a).

          (h) Rights.  Pursuant to the Acquiror's  Rights  Agreement dated as of
March 27, 1996 between  Acquiror and The Bank of New York,  as Rights Agent (the
"Acquiror Rights Plan"), the issuance of each Acquiror Share hereunder (or under
the  Exchange  Offer) shall be  accompanied  by the  associated  right under the
Acquiror Rights Plan.

          (i) No Liens or Calls on Acquiror Shares. Prior to the issuance of any
Acquiror Shares pursuant to this Agreement,  the Principal Stockholder Agreement
or the Exchange  Offer,  the Board of Directors  of the Acquiror  shall,  to the
extent permitted by Bermuda law, (i) irrevocably  waive any lien that has arisen
or may arise on any such Acquiror  Shares under  Bermuda law;  (ii)  irrevocably
declare exempt from Section 14 of Acquiror's  bye-laws all such Acquiror Shares;
and (iii) irrevocably  declare that the Acquiror shall not make any calls on any
such Acquiror Shares pursuant to Section 17 of Acquiror's bye-laws.

     SECTION 2.2.     PAYMENT.

          (a) Exchange  Agent.  As of the Effective  Time,  Acquiror  shall,  on
behalf of Merger Sub, deposit with an exchange agent  theretofore  designated by
the Company and Acquiror (the "Exchange Agent"),  for the benefit of the holders
of shares of Capital Stock  (excluding any shares  described in Sections  2.1(c)
and (d)),  for payment in accordance  with this Article II, through the Exchange
Agent,  the Acquiror  Shares  issuable  pursuant to Sections 2.1(a) and (b) plus
from time to time as necessary cash in an amount  sufficient to make payment for
fractional  shares under  Section  2.1(f) (such  Acquiror  Shares and cash being
hereinafter  referred  to as the  "Exchange  Fund").  Acquiror  shall  cause the
Exchange Agent,  pursuant to irrevocable  instructions,  to deliver the Acquiror
Shares (and cash for  fractional  shares)  contemplated  to be paid  pursuant to
Sections  2.1(a),  (b) and (f) out of the Exchange Fund. The Exchange Fund shall
not be used for any other purpose.

          (b) Payment  Procedures.  Promptly after the Effective Time, but in no
event later than five (5) business  days  thereafter,  Acquiror  shall cause the
Exchange  Agent to mail to each record  holder,  as of the  Effective  Time,  an
outstanding   certificate   (each  a   "Certificate"   and   collectively,   the
"Certificates")   that  immediately   prior  to  the  Effective  Time  evidenced
outstanding  shares of Capital Stock (excluding any shares described in Sections
2.1(c)  and (d));  a form  letter of  transmittal  and  instructions  for use in
effecting the surrender of the Certificates for payment therefor. Upon surrender
to the Exchange Agent of a Certificate, together 



                                       6
<PAGE>

with such letter of transmittalduly  executed, and any other required documents,
the holder of such Certificate shall be entitled to receive in exchange therefor
the   applicable   consideration   set  forth  in  Section   2.1  (the   "Merger
Consideration"),  and  such  Certificate  shall  forthwith  be  canceled.  Until
surrendered  in  accordance  with  the  provisions  of this  Section  2.2,  each
Certificate  shall  represent  for all  purposes  only the right to receive  the
applicable consideration set forth in Section 2.1, without any interest thereon.
Acquiror or the  Surviving  Corporation  shall pay any transfer or other similar
taxes required by reason of the issuance and receipt by the former  stockholders
of the Company of Acquiror Shares pursuant to the provisions of this Article II.

          (c) No  Further  Rights  in  Stock.  All  Acquiror  Shares  paid  upon
conversion of the shares of Capital  Stock in accordance  with the terms of this
Article II shall be deemed to have been paid in full  satisfaction of all rights
pertaining to such shares of Capital Stock.

          (d)  Termination  of Exchange  Fund.  Any portion of the Exchange Fund
that  remains  undistributed  to the  holders of Capital  Stock for one  hundred
eighty (180) days after the Effective Time shall be delivered to Acquiror,  upon
demand, and any holders of Capital Stock that have not theretofore complied with
this Article II shall  thereafter  look only to the  Surviving  Corporation  and
Acquiror for the Merger Consideration to which they are entitled.

          (e) No Liability. Neither Acquiror nor the Surviving Corporation shall
be liable to any holder of shares of Capital  Stock for any  Acquiror  Shares or
cash  delivered  to a  public  official  pursuant  to any  applicable  abandoned
property, escheat or similar law.

          (f)  Lost,  Stolen  or  Destroyed  Certificates.   In  the  event  any
Certificate  evidencing  shares of Capital Stock shall have been lost, stolen or
destroyed, upon the making of an affidavit setting forth that fact by the person
claiming  such lost,  stolen or  destroyed  Certificate  and the  granting  of a
reasonable  indemnity against any claim that may be made against Acquiror or the
Exchange  Agent  with  respect to such  Certificate,  Acquiror  shall  cause the
Exchange  Agent to pay to such person the Merger  Consideration  with respect to
such lost, stolen or destroyed Certificate.

     SECTION 2.3.     COMPANY OPTIONS; STOCK PURCHASE PLAN; WARRANTS.

          (a) Company Options.  As of the Effective Time, each outstanding stock
option (an  "Option")  to purchase  shares of Common  Stock,  including  without
limitation  those granted under the Company's 1986 Stock Option Plan, 1997 Stock
Option Plan and  Non-Employee  Directors'  Stock Option Plan, each as amended to
the date of this Agreement  (collectively,  the "Company  Stock Option  Plans"),
shall be converted  into an option to acquire  Acquiror  Shares,  as provided in
this Section.  Following the Effective Time, each Option shall continue to have,
and shall be




                                       7
<PAGE>


subject to, the terms and  conditions of each  agreement  pursuant to which such
Option was subject  immediately  prior to the Effective Time (including,  in the
case of each Option granted under the Company Stock Option Plans,  the terms and
conditions of the Company Stock Option Plans), except that (A) each Option shall
be  exercisable  for that number of Acquiror  Shares equal to the product of (1)
the  aggregate  number  of shares of Common  Stock  for which  such  Option  was
exercisable  multiplied by (2) the Exchange Ratio,  provided,  however,  that no
Option shall be exercisable for a fractional  Acquiror Share,  and the holder of
an Option  exercisable  for a  fractional  Acquiror  Share  shall be entitled to
receive,  upon exercise thereof,  an offset against the aggregate exercise price
of the  Option  being  exercised  therewith,  such  offset to be  determined  by
multiplying  the  fraction  of a  Acquiror  Share to which a holder of an Option
would be  entitled  to  receive  times the  excess of the  closing  price of the
Acquiror Share as reported on the NYSE on the date of exercise over the exercise
price of such  Option;  (B) the  exercise  price  per share of  Acquiror  Shares
issuable pursuant to each Option shall be equal to the aggregate  exercise price
of such Option at the Effective Time divided by the number of shares of Acquiror
Shares for which such Option shall be  exercisable  as  determined in accordance
with the  preceding  clause (A),  rounded to the next  highest  whole  cent,  if
necessary;  and (C) each outstanding Option shall accelerate and be exercisable,
if not  vested  and  exercisable  at such  time to the  extent,  and only to the
extent, provided in Schedule 2.3. Except as set forth herein, the assumption and
substitution  of options as provided  herein  shall not give the holders of such
options additional benefits or additional vesting rights which they did not have
immediately  prior  to  the  Effective  Time  or  relieve  the  holders  of  any
obligations or restrictions applicable to their options or the shares obtainable
upon exercise of the options. The adjustment provided herein with respect to any
Options that are "incentive  stock  options" as defined in the Internal  Revenue
Code of 1986, as amended (the "Code") shall be and is intended to be effected in
a  manner  that is  consistent  with  continued  treatment  of such  Options  as
"incentive  stock  options"  under of the Code.  The Company  Stock Option Plans
shall be assumed by Acquiror  with respect to all  outstanding  Options,  and no
further  options shall be granted under the Company Stock Option Plans after the
Effective Time.

          Acquiror  shall (i) file one or more  registration  statements on Form
S-8 (or amend existing registration  statements on Form S-8) to become effective
as soon as  practicable  after the  Effective  Time with respect to the Acquiror
Shares subject to Options granted under the Company Stock Option Plans; (ii) use
all  reasonable  efforts to  maintain  the  effectiveness  of such  registration
statements  (and maintain the current status of the  prospectus or  prospectuses
contained  therein) for so long as such options  remain  outstanding;  and (iii)
promptly  prepare  and submit to the NYSE  applications  covering  the  Acquiror
Shares subject to such Options and use commercially  reasonable efforts to cause
such  securities to be approved for listing on or prior to the  Effective  Time,
subject to official notice of issuance.


                                       8
<PAGE>


          Acquiror  shall,  on behalf of Merger Sub,  take such other actions as
are  reasonably  necessary  to revise and adjust each Option as provided in this
Section,  including  providing the holder of each Option as soon as  practicable
after the Effective  Time with an appropriate  option  agreement or amendment to
existing option  agreement.  Acquiror shall take all corporate action reasonably
necessary  to reserve for issuance a  sufficient  number of Acquiror  Shares for
delivery upon the exercise of Options. To the extent that the provisions of this
Section 2.3(a) require amendments to the Company Stock Option Plans, the Company
shall  take all  actions  necessary  to make  such  amendments  to allow for the
treatment of Options as provided for in this Section 2.3(a).

          (b) Employee Stock Purchase Plan. Effective as of the last trading day
of the Common Stock prior to the Effective  Time,  the then  applicable  Payroll
Deduction  Period, as defined in the Company's 1996 Employee Stock Purchase Plan
(the "Employee Stock Purchase Plan"), shall be terminated and shall be deemed to
have  ended  on the  last day of the last  payroll  period  ending  prior to the
Effective Time; and the rights of each participating employee shall be deemed to
be  automatically  exercised as of such last trading day of the Common Stock, as
provided in Sections 10 and 26(c) of the Employee Stock Purchase Plan.

          (c) Warrants.  As of the Effective Time, each  outstanding  warrant (a
"Warrant") to purchase  shares of Common Stock shall be converted into a warrant
to acquire Acquiror Shares, as provided in this Section. Following the Effective
Time,  each Warrant shall  continue to have,  and shall be subject to, the terms
and  conditions  of each  agreement  pursuant to which such  Warrant was subject
immediately prior to the Effective Time, except as set forth in this Section and
except that (A) each such Warrant shall be exercisable  for that number of whole
Acquiror  Shares equal to the product of (x) the  aggregate  number of shares of
Common  Stock for which  such  Warrant  was  exercisable  multiplied  by (y) the
Exchange Ratio;  provided,  however,  that no Warrant shall be exercisable for a
fractional  Acquiror  Share,  and the  holder  of a  Warrant  exercisable  for a
fractional  Acquiror Share shall be entitled to receive,  upon exercise thereof,
an offset against the aggregate  exercise  price of the Warrant being  exercised
therewith,  such  offset to be  determined  by  multiplying  the  fraction of an
Acquiror Share to which a holder of a Warrant would be entitled to receive times
the excess of the closing price of the Acquiror Share as reported on the NYSE on
the date of  exercise  over the  exercise  price  of such  Warrant,  and (B) the
exercise  price per Acquiror  Share  issuable  pursuant to such Warrant shall be
equal to the  aggregate  exercise  price of such Warrant at the  Effective  Time
divided  by the  number of  Acquiror  Shares  for which  such  Warrant  shall be
exercisable as determined in accordance with the preceding  clause (A),  rounded
to the next highest whole cent, if necessary.

          Acquiror  shall,  on behalf of Merger Sub,  take such other actions as
are  reasonably  necessary to revise and adjust each Warrant as provided in this
Section,  including  providing the holder of each Warrant as soon as practicable
after the




                                       9
<PAGE>

Effective  Time with an appropriate  warrant  agreement or amendment to existing
warrant agreement. Acquiror shall take all corporate action reasonably necessary
to reserve for issuance a sufficient number of Acquiror Shares for delivery upon
the exercise of Warrants.

     SECTION 2.4.     STOCK TRANSFER BOOKS.

          At the Effective  Time,  the stock  transfer books of the Company with
respect  to all shares of capital  stock of the  Company  shall be closed and no
further  registration  of  transfers  of such  shares  of  capital  stock  shall
thereafter  be made on the  records of the  Company.  On or after the  Effective
Time,  if any  Certificates  for shares of Capital Stock  (excluding  any shares
described in Sections 2.1(c) and (d)) are presented to the Exchange  Agent,  the
Surviving  Corporation or Acquiror for any reason,  such  Certificates  shall be
canceled  and  exchanged  as provided in this  Article II,  except as  otherwise
provided by law.

     SECTION 2.5.     CERTAIN ADJUSTMENTS.

          If between the date hereof and the  Effective  Time,  the  outstanding
shares of Capital Stock or of Acquiror  Shares shall be changed into a different
number of shares by reason of any reclassification,  recapitalization, split-up,
combination  or exchange of shares,  or any  dividend  payable in stock or other
securities shall be declared thereon with a record date within such period,  the
Exchange  Ratio  shall be  adjusted  accordingly  to provide  to the  holders of
Capital Stock the same economic  effect as  contemplated by this Agreement prior
to such reclassification,  recapitalization,  split-up, combination, exchange or
dividend;  provided,  however,  that in the event that,  prior to the  Effective
Time, Acquiror consummates any merger, amalgamation or consolidation as a result
of which Acquiror Shares being issued hereunder are neither  registered with the
SEC pursuant to Section  12(b) or 12(g) of the  Exchange Act (as defined  below)
nor converted into the right to receive  securities so registered,  the Exchange
Ratio shall be determined  assuming  that the  Volume-Weighted  Average  Trading
Price was equal to the per share amount of consideration a common stockholder of
Acquiror received on the date of consummation of such transaction.

                                  ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby  represents and warrants to Acquiror and Merger Sub
as follows:

     SECTION 3.1.     ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.

          (a) The Company and each  Subsidiary (as defined below) of the Company
(each a "Company Subsidiary" and collectively,  the "Company



                                       10
<PAGE>

Subsidiaries") is a corporation or partnership duly organized,  validly existing
and in good standing under the laws of the jurisdiction of its organization. The
Company and each Company  Subsidiary is duly  qualified to conduct its business,
and is in good  standing,  in  each  jurisdiction  where  the  character  of its
properties owned,  operated or leased or the nature of its activities makes such
qualification  necessary,  except  for  such  failures  which  would  not in the
aggregate have a Company Material Adverse Effect (as defined below). The Company
and each Company Subsidiary has the requisite corporate or partnership power and
authority and any necessary governmental authority, franchise, license or permit
to own,  operate,  lease  and  otherwise  to hold and  operate  its  assets  and
properties  and to carry on its  businesses as now being  conducted,  except for
such  failures  which  would not have a Company  Material  Adverse  Effect.  The
Company has no Subsidiaries (as defined below) or any equity or similar interest
in any entity  other than those listed in Schedule  3.1.  Except as set forth in
Schedule  3.1,  each Company  Subsidiary  is a  wholly-owned  direct or indirect
subsidiary of the Company.  As used herein,  the term "Company  Material Adverse
Effect"  means any material  adverse  effect on the business  (where  "business"
shall be deemed  to  include  the Orion 1  satellite  and the  proposed  Orion 2
satellite and Orion 3 satellite),  assets or condition (financial or otherwise),
liabilities or operations of the Company and the Company Subsidiaries taken as a
whole.

          (b) For purposes of this Agreement, a "Subsidiary" of any person means
any corporation,  partnership, joint venture or other legal entity of which such
person (either alone or through or together with any other Subsidiary) (i) owns,
directly  or  indirectly,  fifty  percent  (50%) or more of the  capital  stock,
partnership  interests  or other  equity  interests  the  holders  of which  are
generally  entitled to vote for the  election of the board of directors or other
governing body of such  corporation,  partnership,  joint venture or other legal
entity; or (ii) possesses, directly or indirectly, control over the direction of
management or policies of such corporation,  partnership, joint venture or other
legal entity (whether through  ownership of voting  securities,  by agreement or
otherwise).

     SECTION 3.2.     CERTIFICATE OF INCORPORATION AND BYLAWS.

          The  Company  has  heretofore  delivered  to  Acquiror a complete  and
correct copy of the certificate or articles of  incorporation  and the bylaws of
the Company and each Company  Subsidiary  that is a  corporation,  and a correct
copy  of the  partnership  agreement  for  each  Company  Subsidiary  that  is a
partnership,  each as amended to date.  Each such  certificate  or  articles  of
incorporation,  bylaws and  partnership  agreement  is in full force and effect.
Neither the Company nor any Company  Subsidiary  is in  violation  of any of the
provisions of its respective certificate or articles of incorporation, bylaws or
partnership agreement.

granted by the Company or any Company Subsidiary since June 30, 1997.

          Except  as set  forth  in  Schedule  3.3,  there  are  no  outstanding
contractual  obligations  of the  Company  to  repurchase,  redeem or  otherwise
acquire  any shares of its  capital  stock.  All of the  issued and  outstanding

issued  and  are  fully  paid  and  nonassessable,  and  all of the  partnership
interests  of each  Company  Subsidiary  that is a  partnership  have  been duly

Subsidiary that is a partnership,  all of the partnership interests owned by the
Company, and with respect to each Company Subsidiary that is a corporation,  all
of the  outstanding  shares of capital stock owned by the Company,  are owned by
the  Company  free  and  clear  of  any  liens,  security  interests,   pledges,

     SECTION 3.4.     AUTHORITY.

          The Company has the necessary  corporate  power and authority to enter
into this  Agreement and the Principal  Stockholder  Agreement  and,  subject to

Each of this  Agreement  and the Principal  Stockholder  Agreement has been duly
executed  and  delivered by the Company  and,  assuming  the due  authorization,

     SECTION 3.5.     NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

          (a) The  execution  and delivery of this  Agreement  and the Principal
Stockholder  Agreement by the Company do not, and the performance by the Company
of its obligations under this Agreement and the Principal  Stockholder Agreement
will  not,  (i)  conflict  with  or  violate  the  certificate  or  articles  of
incorporation,  bylaws or  partnership  agreement  of the Company or any Company
Subsidiary,  (ii) subject to obtaining  the approvals  and  compliance  with the
requirements  set forth in Section  3.5(b),  conflict  with or violate  any law,

the  Company  or any  Company  Subsidiary  or by which  any of their  respective
properties  is bound or affected,  or (iii) except as set forth in Schedule 3.5,

alterations or occurrences  that would not prevent or delay  consummation of the
Merger in any material respect, or otherwise prevent the Company from performing
its obligations under this Agreement in any material respect, and would not have
a Company Material Adverse Effect.

          (b) The execution  and delivery of this  Agreement by the Company does
not, and the performance of this Agreement by the Company will not,  require any
consent,  approval,  authorization  or permit of, or filing with or notification

the consents,  approvals,  authorizations  or permits described in Schedule 3.5,
and (C) filing and  recordation of appropriate  merger  documents as required by
Delaware  Law and  (ii)  where  failure  to  obtain  such  consents,  approvals,
authorizations or permits,  or to make such filings or notifications,  would not
prevent  or  delay  consummation  of the  Merger  in any  material  respect,  or
otherwise  prevent  the  Company  from  performing


                                       14
<PAGE>

its obligations under this Agreement in any material respect, and would not have

     SECTION 3.6.     SEC FILINGS; FINANCIAL STATEMENTS.

          (a) The Company (or its  predecessor,  Constellation  Oldco  Services,
Inc.,  now a 100%  owned  Company  Subsidiary  ("Oldco"))  has filed all  forms,
reports, statements and other documents required to be filed with the Securities
and Exchange  Commission  (the "SEC") since August 4, 1995,  the date of Oldco's
initial public offering,  and has heretofore furnished to Acquiror,  in the form
filed with the SEC since such date,  together with any amendments  thereto,  its
(i) Annual Reports on Form 10-K, (ii) all Quarterly  Reports on Form 10-Q, (iii)
all proxy  statements  relating to meetings of  stockholders  (whether annual or

Reports").  As of their  respective  filing  dates,  the Company SEC Reports (i)
complied  as to form in all  material  respects  with  the  requirements  of the
Exchange  Act and the  Securities  Act,  and (ii) did not at the time  they were
filed  contain  any  untrue  statement  of a  material  fact or omit to  state a
material fact required to be stated  therein or necessary to make the statements
therein,  in the light of the  circumstances  under  which they were  made,  not
misleading.

          (b)  The  audited  consolidated  financial  statements  and  unaudited
interim financial  statements of the Company included in the Company SEC Reports
comply  as  to  form  in  all  material  respects  with  applicable   accounting
requirements  and with  the  published  rules  and  regulations  of the SEC with
respect  thereto.  The  financial  statements,  including  all related notes and
schedules,  contained in the Company SEC Reports (or  incorporated  by reference
therein)  present  fairly in all material  respects the  consolidated  financial
position  of the  Company  (or  Oldco,  as the  case  may be)  and  the  Company
Subsidiaries as at the respective dates thereof and the consolidated  results of
operations and cash flows of the Company (or Oldco,  as the case may be) and the
Company  Subsidiaries  for the periods  indicated,  in accordance with generally
accepted  accounting  principles  applied on a consistent  basis  throughout the
periods  involved  (except as may be noted  therein)  and subject in the case of
interim financial statements to normal year-end adjustments.

     SECTION 3.7.     ABSENCE OF CERTAIN CHANGES OR EVENTS.

          Except as set forth in Schedule 3.7,  since June 30, 1997, the Company
and the Company Subsidiaries have not incurred any material liability, except in
the ordinary course of business  consistent  with their past practices,  and the
Company and the Company Subsidiaries have conducted their respective  businesses
in the ordinary course consistent with their past practices. Except as set forth
in  Schedule  3.7,  since  June 30,  1997,  there has not been any change in the
business (where  "business" shall be deemed to include the Orion 1 satellite and
the proposed



                                       15
<PAGE>


Orion 2 satellite and Orion 3 satellite),  condition (financial or otherwise) or
results of operations of the Company and the Company Subsidiaries, including any
transaction,  commitment,  dispute, damage,  destruction or loss, whether or not
covered by  insurance,  or other event of any  character  (whether or not in the
ordinary course of business) individually or in the aggregate, which has had, or
is reasonably likely to have, a Company Material Adverse Effect,  other than (i)
any change  arising  out of matters of a general  economic  nature,  or (ii) any
change  arising  out  of  matters  affecting  the  satellite  industry,   either
international or national, generally (including, but not limited to, competition
from other satellite systems or service  providers and legislation,  rulemaking,
regulation or regulatory  practice by any  governmental  agency or international
rulemaking body such as the International Telecommunication Union).

     SECTION 3.8.     ABSENCE OF LITIGATION.

          Except as set forth in Schedule  3.8, as of the date hereof  there are
(a) no claims, actions, suits, investigations, or proceedings pending or, to the
Company's  knowledge,  threatened  against  the  Company  or any of the  Company
Subsidiaries before any court, administrative, governmental, arbitral, mediation
or regulatory  authority or body, domestic or foreign,  that would be reasonably
likely to have a Company Material  Adverse Effect,  or that challenge or seek to
prevent, enjoin, alter or materially delay the transactions contemplated hereby,
and (b) no judgments,  decrees, injunctions or orders of any Governmental Entity
or arbitrator  outstanding  against the Company or any Company  Subsidiary  that
would reasonably be likely to have a Company Material Adverse Effect.

     SECTION 3.9.     LICENSES AND PERMITS; COMPLIANCE WITH LAWS.

          Except as set forth in Schedule 3.9:

          (a) Set forth on Schedule  3.9(a) is a true and  complete  list of all
permits,  licenses and  approvals  (none of which has been modified or rescinded
and all of which are in full force and effect)  from all  Governmental  Entities
held by the Company ("Company Permits"), except in each case for Company Permits
whose absence or revocation  would not  individually  or in the aggregate have a
Company Material  Adverse Effect (all of the foregoing,  which are denoted by an
asterisk on Schedule 3.9(a),  being referred to herein  collectively as the "Key
Company Permits"); provided, however, that Schedule 3.9(a) shall not be required
to include a list of Company Permits for Very Small Aperture  Terminals (VSATs).
The Key Company Permits listed on Schedule 3.9(a) include,  without  limitation,
all Key  Company  Permits  (i) issued by the FCC to the  Company or any  Company
Subsidiary,  (ii)  authorizing  the  construction,  launch or operation in their
assigned  orbital  locations  of  Company   Satellites  (as  defined  below)  or
construction  and  operation  of Company  Ground  Stations  (as defined  below),
including  without  limitation  the agreement  with the Republic of the Marshall
Islands and the license





                                       16
<PAGE>

granted by the Federal  Republic of Germany,  and (iii) issued to the Company or
any Company  Subsidiary by Governmental  Entities that regulate  broadcasting or
communications services,  authorizing the Company or the Company Subsidiaries to
provide  broadcasting or communications  services.  The parties acknowledge that
(i) the approval for the Orion 2 satellite is a conditional  approval subject to
the conditions  described in the orders and agreements relating thereto and (ii)
the  approval  for the Orion 3  satellite  results  from an  agreement  with the
Republic of the Marshall Islands (and no further  regulatory  approvals from the
Republic of the Marshall Islands are necessary for such construction, launch and
operation of the Orion 3 satellite).

          Schedule  3.9(a)  also  sets  forth a true  and  complete  list of all
Company Permits issued by the FCC, the Marshall  Islands or the Federal Republic
of Germany (including  applications  therefor) which are not Key Company Permits
or VSATs ("Other Permits").  To the best of the Company's  knowledge,  the Other
Permits are in full force and effect or, in the case of  applications  therefor,
the  Company  knows of no reason why the same  should not be  granted.  Schedule
3.9(a) also sets forth a true and complete list of all pending  applications for
Company Permits that would be Key Company Permits  required to be listed in such
Schedule if issued or granted and if the satellites which they relate were owned
by the  Company,  all  pending  applications  by  the  Company  or  any  Company
Subsidiary  with the FCC and all  pending  applications  by the  Company  or any
Company Subsidiary for modification, extension or renewal of Key Company Permits
(the "Key Applications").

          The Key Company  Permits  held by the Company or Company  Subsidiaries
and listed on Schedule  3.9(a) include all permits,  licenses and approvals from
all  Governmental  Entities  which are necessary for the Company and the Company
Subsidiaries  to (i)  operate  the  Orion 1  satellite  in its  present  orbital
location and provide communications services (and broadcast services, if any are
provided  by the  Company or Company  Subsidiaries)  therefrom,  operate  ground
stations communicating  therewith,  including,  without limitation,  the related
broadcasting facility assets consisting of land, building, fixtures,  equipment,
improvements  (if any) and  telemetry,  tracking and control  equipment  that is
owned or leased by the Company or a Company  Subsidiary  (each a "Company Ground
Station" and  collectively  the "Company Ground  Stations"),  and own, lease and
operate their  properties and to carry on their business as currently  conducted
using the Orion 1 satellite,  and (ii) construct,  launch and operate,  at their
assigned  orbital  locations,  the  proposed  Orion  2 and  Orion  3  satellites
(collectively with the Orion 1 satellite,  the "Company Satellites"),  except as
set forth in the last sentence of the first paragraph of this subsection (a) and
in each case for permits,  licenses and  approvals  whose  absence or revocation
would not  individually  or in the  aggregate  have a Company  Material  Adverse
Effect (without giving effect to any limitation as of  "materiality" or "Company
Material Adverse Effect" in the definition of Key Company Permits).


                                       17

          Each of the Company and the Company  Subsidiaries  has  fulfilled  and
complied in all material  respects  with its  obligations  under each of the Key
Company Permits and the Key Applications  owned, held or possessed by it, and no
event has occurred or condition or state of facts exists which  constitutes  or,
after  notice or lapse of time or both,  would  constitute  a breach or  default
under any Key Company  Permit or Key  Applications  and which  permits or, after
notice or lapse of time or both,  would permit  revocation or termination of any
such Key  Company  Permit or Key  Application,  and  neither the Company nor any
Company  Subsidiary  has  received or has  knowledge  of any  written  notice of
cancellation  or default or of any dispute  concerning any Key Company Permit or
Key  Application,  or of any such event,  condition or state of facts that would
constitute a default the effect of which would be revocation or  termination  of
such Key Company  Permit or Key  Application,  except,  in each case, any of the
foregoing  which  individually  or in the  aggregate  would  not have a  Company
Material Adverse Effect.  Each of the Key Company Permits is validly held by the
entities listed on Schedule 3.9(a),  is in full force and effect in all material
respects,  is free and clear of all  liens  (other  than  permitted  liens),  is
unimpaired  in any  material  respect by acts or omissions of the Company or its
employees,  partners  or  affiliates,  will expire on the date shown on Schedule
3.9(a),  is valid for the balance of its current term, and is not subject to any
restriction or condition that limits in any material  respect the full operation
of the Company's and Company Subsidiaries' business as now operated.

          The Company has not  received  any  complaint  that any of the Company
Satellites or Company Ground Stations is causing  objectionable  interference to
the transmissions or reception of any other radio communications  facility,  and
to the  Company's  best  knowledge,  no other radio  communications  facility is
causing  objectionable  interference to the transmissions from or the receipt of
signals by any Company  Satellite  or Company  Ground  Station.  None of the Key
Company  Permits  issued  prior to the date hereof is the subject of any pending
renewal  application;  no renewal of any Key  Company  Permit  issued by the FCC
would  constitute a major  environmental  action under the rules and regulations
promulgated by the FCC (the "FCC Rules"),  excluding the impact of the FCC's new
RF  radiation  rules  adopted by the FCC in the ET Docket No. 93-62 on August 1,
1996;  and the  Company is not aware of any reason why the Key  Company  Permits
will not be renewed in the ordinary course or why any of the Key Company Permits
might be revoked.  The Company knows of the existence of no fact that, under any
Key Company  Permits and present law  relating  thereto,  would  disqualify  the
Company from consummating the Merger within the time contemplated  herein (other
than matters disclosed on Schedule 5.14).

          All  information  contained  in any pending Key  Application  is true,
correct and  complete in all  material  respects.  The Company has duly filed or
caused to be filed with the FCC or any other  Governmental  Entity all  required
material reports, statements, documents,  registrations,  filings or submissions
with  respect to the  operations  of the business of the Company and the Company




                                       18

Subsidiaries,  the Key Company Permits, the Company's and Company  Subsidiaries'
ownership  of their  assets and the pending  applications  by the Company or any
Company  Subsidiary for Key Company  Permits or for  modification,  extension or
renewal of Company  Permits,  in each case as  required  by the FCC or any other
Governmental  Entity.  All such filings  complied in all material  respects with
applicable laws when made and no material  deficiencies  have been asserted with
respect to any such filings.

          Except for rulemaking  proceedings affecting the satellite industry in
general,  no judgment,  decree,  order or notice of violation has been issued by
the FCC (or other Governmental Entity) which permits or contemplates revocation,
modification  or  termination  or any of the Key Company  Permits or which would
result in any material impairment of any rights thereunder.  The business of the
Company  and the  Company  Subsidiaries  (where  "business"  shall be  deemed to
include the Orion 1 satellite  and the  proposed  Orion 2 satellite  and Orion 3
satellite),  is not being conducted in violation of any applicable law, statute,
ordinance,  regulation  or judgment or any Key Company  Permit,  order,  decree,
concession,  grant or other  authorization of any Governmental  Entity,  in each
case except for violations that, individually or in the aggregate,  would not be
reasonably  likely  to  have a  Company  Material  Adverse  Effect.  Except  for
rulemaking   proceedings   affecting  the  satellite  industry  in  general,  no
complaints,  proceedings or applications  are pending,  or to the Company's best
knowledge,  threatened,  at the FCC or any other Governmental Entity, that would
result in the  revocation,  forfeiture,  adverse  modification,  non-renewal  or
suspension  of any of the Key  Company  Permits,  the denial of any  pending Key
Application,  the issuance  against the Company or any Company  Subsidiary  of a
cease and desist order, or the imposition of any  administrative  actions by the
FCC or any other Governmental Entity with respect to the Key Company Permits, in
each case that would have, whether  individually or in the aggregate,  a Company
Material Adverse Effect.

          (b) Neither the Company nor any Company  Subsidiary  or affiliate  has
taken,  is taking or will take, or has allowed or will allow on its behalf to be
taken,  any action which would have  violated or would violate the United States
Foreign  Corrupt  Practices Act of 1977,  the US Export  Administration  Act, as
amended, or any laws to which such party or persons is subject, relating in each
case  to  payments  for the  purpose  of  influencing  an act or  decision  of a
Governmental  Entity  or  government   official,   except  for  violations  that
individually  or in the  aggregate  would  not have a Company  Material  Adverse
Effect;  provided,  however,  that nothing in this  sentence  shall be deemed to
subject  any party or person to any law to which such party or person  would not
otherwise  be subject.  Each of the Company and the Company  Subsidiaries  is in
material  compliance  with all  domestic  and, to the  knowledge of the Company,
foreign laws  restricting  or  regulating  the export of  technology  to foreign
countries, except for violations that individually or in the aggregate would not
have a Company Material Adverse Effect.

similar intergovernmental  entities (collectively the "IGO Determinations") with
respect to the Company Satellites that are needed to operate the business of the
Company and the Company Subsidiaries as it is now being conducted. Except as set
forth on such schedule, the Company is not aware of any material difficulties in
obtaining  any other  determinations  from such  entities  with  respect  to any
satellite now operated by the Company or any Company Subsidiary or for which the
Company or any Company  Subsidiary has applied for a Company Permit,  except for
those that  individually or in the aggregate  would not have a Company  Material
Adverse Effect.

     SECTION 3.10.     TAXES.

          Except as set forth in  Schedule  3.10,  the  Company  and the Company
Subsidiaries  have  prepared  and filed on a timely  basis with all  appropriate
Governmental Entities all material returns, reports,  information statements and
other  documentation  in respect of Taxes that they are  required  to file on or
prior to the Closing Date or by the date therefor including extensions,  and all

correct and complete in all material  respects.  Except as set forth in Schedule
3.10,  the  Company  and the  Company  Subsidiaries  have paid in full all Taxes
(other than Taxes,  the failure to pay which would not,  individually  or in the
aggregate,  have a Company Material Adverse Effect) due on or before the Closing
Date and, in the case of material  Taxes  accruing on or before the Closing Date
that are not due on or before the Closing  Date,  the Company has made  adequate
provisions in its books and records and financial  statements  for such payment.
Except as set forth in Schedule 3.10,  the Company and the Company  Subsidiaries
have  withheld   from  payments  made  to  its  present  or  former   employees,
contractors,  officers and directors, creditor or other third party, all amounts
required  by  law  to  be  withheld   except  where  the  liability  would  not,
individually or in the aggregate,  have a Company Material  Adverse Effect,  and
has, where required,  remitted such amounts within the applicable periods to the
appropriate Governmental Entities. In addition,  except as set forth in Schedule
3.10, (a) there are no  assessments  of, or claims  against,  the Company or the
Company  Subsidiaries  with  respect to Taxes,  the  liability  for which would,
individually or in the aggregate,  have a Company Material Adverse Effect,  that
are  outstanding;  (b) no  Governmental  Entity is conducting an  examination or
audit of the Company or any Company  Subsidiary  in respect of Taxes and neither
the  Company  nor  any  Company  Subsidiary  has  received  notice  of any  such
examination or audit from any Governmental  Entity;  and (c) neither the Company
nor any Company  Subsidiary  has executed or filed any  agreement  extending the
period of assessment or collection of any Taxes which remain in effect.  For the
purpose of this Agreement, the term "Tax" (including,  with correlative meaning,
the terms  "Taxes"  and  "Taxable")  shall  include,  except  where the  context
otherwise  requires,  all federal,  state,  local and foreign  income,  profits,
franchise,   gross  receipts,   payroll,




                                       20

sales,  employment,  use,  property,  withholding,  excise,  occupancy and other
taxes,  duties or assessments or claims of any nature whatsoever,  together with
all interest, penalties and additions imposed with respect to such amounts.

     SECTION 3.11.     INTELLECTUAL PROPERTY.

          Schedule  3.11 sets forth a listing and  description  of all  material
domestic,  foreign, common law, registered and pending applications for patents,
trademarks, service marks, logos, slogans, designs, copyrights, trade names, and
all material  intellectual  property  licenses running to or from the Company or
any Company  Subsidiary  relating to the Company's or any Company  Subsidiaries'
businesses or owned by the Company or any Company  Subsidiary.  Unless expressly
set forth  otherwise on Schedule 3.11, the Company and the Company  Subsidiaries
own (or where  indicated on Schedule 3.11,  have a right to use), free and clear
of any liens, security interests, encumbrances or claims of others, all patents,
trademarks,  service marks, logos,  slogans,  designs,  copyrights,  tradenames,
design  registrations,  and other intellectual  property listed on Schedule 3.11
and any trade secrets,  know-how,  confidential  information,  material computer
programs (including any source code),  documentation,  engineering and technical

each case material to the conduct of the business of the Company and the Company
Subsidiaries taken as a whole (all of the foregoing items collectively  referred
to as the  "Company  Intellectual  Property").  Except as set forth on  Schedule
3.11, (a) no proceedings are pending or, to the Company's knowledge,  threatened
in writing,  which challenge the validity of the ownership by the Company and/or
any Company Subsidiary of the Company Intellectual Property; (b) the Company has
no  knowledge  of any  infringement  or  infringing  use  of any of the  Company
Intellectual  Property or licenses by any person or entity,  and the Company and
the Company  Subsidiaries  have, and as of the Closing Date will have,  good and
valid title to all of the Company Intellectual  Property owned by the Company or
Company Subsidiaries and their licenses and other rights to use will be adequate
for conducting the  businesses of the Company and the Company  Subsidiaries  and
enforceable in accordance with their terms; (c) to the Company's  knowledge,  no
infringement of any material  intellectual  property right or other  proprietary
right of any third party has occurred or will result in any way from the signing
and  execution  of  this  Agreement  or  the  consummation  of any or all of the
transactions  contemplated  hereby,  and no  written  claim has been made by any
third party based upon an allegation of any such infringement;  (d) the material
Company  Intellectual  Property  is valid and in full  force and  effect  and no
aspect thereof is subject to any outstanding order, ruling, decree,  judgment or
stipulation by or with any court,  arbitrator or administrative  agency; and (e)
there are no restrictions on the direct or indirect transfer of any license,  or
any interest therein,  held by the Company or any Company  Subsidiary in respect
of the Company Intellectual Property.

     SECTION 3.12.     MATERIAL CONTRACTS.

          (a) Schedule 3.12(a) sets forth a complete and correct list, as of the
date of this  Agreement,  of all  agreements of the following  type to which the
Company or a Company  Subsidiary is a party or may be bound  (collectively,  the
"Company Material Contracts"): (i) agreements filed as an exhibit to the Company
SEC Reports and each  agreement  that would have been required to be filed as an
exhibit to the Company SEC Reports if such agreement had been entered into as of
the date of filing any such  Company SEC  Report;  (ii)  employment,  severance,
termination,  consulting  and  retirement  agreements;  (iii)  loan  agreements,
indentures,  letters of  credit,  mortgages,  notes and other  debt  instruments
evidencing  indebtedness in excess of five hundred thousand dollars  ($500,000),
other than those relating to intercompany debt among the Company and the Company
Subsidiaries;  (iv)  agreements that require  aggregate  future payments of more
than five hundred  thousand dollars  ($500,000)  (other than purchase orders and
sales contracts entered into in the ordinary course of business); (v) agreements
involving  payments in excess of two hundred fifty thousand  dollars  ($250,000)
concerning any provisions  with respect to a "change in control";  (vi) material
agreements  with any key employee,  director,  officer or  beneficial  owner (as
determined  pursuant to Rule 13d-3  promulgated under the Exchange Act) of 5% or
more of the Company's Common Stock; and (vii) agreements for a remaining term of
five  (5)  years  or more  with  any  customer  of the  Company  or any  Company
Subsidiary.

          (b) Except as set forth in Schedule 3.12(b),  all the Company Material
Contracts  are valid and in full force and effect on the date  hereof  except to
the extent they have  previously  expired in  accordance  with their terms,  and
neither the Company nor any Company  Subsidiary  has (or has any knowledge  that
any party  thereto  has)  violated any  provision  of, or committed or failed to
perform  any act  which  with or  without  notice,  lapse of time or both  would
constitute a default under the  provisions  of, any Company  Material  Contract,
except  for  defaults  which,  individually  or  in  the  aggregate,  would  not
reasonably  be  expected to have a Company  Material  Adverse  Effect.  True and
complete  copies  of all  Company  Material  Contracts  have been  delivered  to
Acquiror or made available for inspection by Acquiror.

          (c) As of August 31, 1997,  the  contracts,  agreements,  commitments,
arrangements,   leases  (including  with  respect  to  personal  property)  that
represent  obligations  of third  parties to make payments to the Company or any
Company  Subsidiary,  as the case may be, in  exchange  for the sale or lease of
transponder  capacity,  have an aggregate stated amount of unpaid payments owing
to the Company or any Company  Subsidiary,  as the case may be, of approximately
$263 million over the remaining  stated term of such contracts  (the  "Backlog")
(prior to any  reserve for  doubtful  accounts or other  similar  allowances  or
deductions).  The Backlog represents amounts that,  assuming the due performance
by each party of



                                       22
<PAGE>


its  obligations  under each contract and the  occurrence of no event that would
permit  termination of a contract  without  liability to the terminating  party,
will be due for,  and will arise out of, bona fide sales and  delivery of goods,
performance of services and other business  transactions,  unless the underlying
contract  thereto is properly  terminated in accordance  with the terms thereof.
Except as set forth on  Schedule  3.12(c),  neither  the Company nor any Company
Subsidiary  is, or has received any notice or has any  knowledge  that any other
party is, in default in any material respect under any contract representing any
material  portion  of  the  Backlog,  other  than  (i)  payment  defaults  under
transponder  lease  agreements which are not more than 90 days past due and (ii)
defaults or terminations  under  transponder  lease agreements that are promptly
replaced by contracts  providing for reasonably  equivalent or superior  backlog
payments.

     SECTION 3.13.     EMPLOYEE BENEFIT PLANS.

          (a) Schedule  3.13 sets forth a list of all of the  material  pension,
retirement, profit-sharing,  deferred compensation, stock option, employee stock
ownership,  severance  pay,  vacation  or  bonus  plans or  agreements  or other
material  incentive  plans or agreements,  all other material  written  employee
programs,  arrangements  or agreements and all other material  employee  benefit
plans or fringe  benefit plans,  including,  without  limitation,  all "employee
benefit  plans"  as that  term  is  defined  in  Section  3(3)  of the  Employee
Retirement  Income  Security Act of 1974,  as amended  ("ERISA")  (collectively,
"Benefit  Plans"),  currently  adopted,  maintained by, sponsored in whole or in
part  by,  or  contributed  to by the  Company  or  any  entity  required  to be
aggregated  with  the  Company  which is a member  of the  "controlled  group of
corporations" which includes the Company within the meaning of Section 414(b) or
(c) of the Code (each, a "Company Commonly  Controlled  Entity") for the benefit
of present and former  employees or directors of the Company and of each Company
Subsidiary  or their  beneficiaries,  or  providing  benefits to such persons in
respect of  services  provided to any such entity  (collectively,  the  "Company
Benefit Plans").  Any Company Benefit Plan which is an "employee pension benefit
plan," as that term is defined in Section  3(2) of ERISA,  is referred to herein
as a "Company ERISA Plan."

          (b) Each of the  Company  Benefit  Plans  intended  to be  "qualified"
within  the  meaning of Section  401(a) of the Code has been  determined  by the
Internal Revenue Service to be so qualified and, to the Company's knowledge,  no
circumstances  exist that could  reasonably be expected by the Company to result
in the revocation of any such  determination.  Each of the Company Benefit Plans
is in compliance  with the applicable  terms of ERISA and the Code and any other
applicable  laws,  rules and  regulations the breach or violation of which could
result in a material liability to the Company or any Company Commonly Controlled
Entity.


                                       23
<PAGE>


          (c) No Company ERISA Plan which is a defined  benefit pension plan has
any  "unfunded   current   liability,"  as  that  term  is  defined  in  Section
302(d)(8)(A)  of ERISA,  and the present  fair market value of the assets of any
such plan equals or exceeds the plan's  "benefit  liabilities,"  as that term is
defined in Section 4001(a)(16) of ERISA, when determined under actuarial factors
that would apply if the plan terminated in accordance with all applicable  legal
requirements.

          (d) Except as disclosed in Schedule  3.13, no Company  Benefit Plan is
or has been a multiemployer plan within the meaning of Section 3(37) of ERISA (a
"Multiemployer  Plan").  Neither the Company nor any Company Commonly Controlled
Entity has  completely or partially  withdrawn from any  Multiemployer  Plan. No
termination  liability to the Pension Benefit Guaranty Corporation or withdrawal
liability to any  Multiemployer  Plan that is material in the aggregate has been
or is reasonably  expected to be incurred with respect to any Multiemployer Plan
by the Company or any Company Commonly Controlled Entity.

          (e) The Company has furnished to Acquiror  complete copies,  as of the
date  hereof,  of all of the  Company  Benefit  Plans that have been  reduced to
writing,  together with all documents  establishing or constituting  any related
trust,  annuity contract,  insurance contract or other funding  instrument.  The
Company has furnished to Acquiror  complete copies of all existing  current plan
summaries,  employee booklets, personnel manuals and other material documents or
written materials concerning the Company Benefit Plans.

                  (f) Except as set forth on Schedule 3.13, there are no Company
Benefit  Plans which  provide for  payments  which would not be  deductible  for
Federal income tax purposes by reason of Section 280G of the Code.

     SECTION 3.14.     PROPERTIES; ASSETS.

          (a) Except as set forth in Schedule 3.14(a), the Company or one of the
Company Subsidiaries (a) has good and marketable title to all the properties and
assets  reflected in the  consolidated  balance sheet of the Company dated as of
June 30, 1997 (the "Company Balance Sheet") as being owned by the Company or one
of the Company  Subsidiaries  (except  properties sold or otherwise  disposed of
since the date thereof in the ordinary  course of business),  or acquired  after
the date thereof which are material to the Company's  business on a consolidated
basis,  free and clear of all  Encumbrances  except (i) statutory liens securing
payments not yet due, and (ii) such  imperfections or  irregularities  of title,
claims, liens, charges,  security interests or encumbrances as do not materially
affect the use of the properties or assets subject  thereto or affected  thereby
or otherwise  materially impair business operations at such properties,  and (b)
is the lessee of all leasehold  estates  reflected in the Company  Balance Sheet
(except for leases that have  expired by their terms since the date  thereof) or
acquired  after  the date  thereof  which  are  material  to its  business  on a
consolidated basis and is in possession of the 





                                       24
<PAGE>
 

properties  purported  to be leased  thereunder,  and, to the  knowledge  of the
Company,  each such lease is valid without default thereunder by the lessee. The
assets and  properties of the Company and the Company  Subsidiaries,  taken as a
whole,  are in good  operating  condition  and  repair  (ordinary  wear and tear
excepted),  and constitute  all of the assets and properties  which are required
for the businesses and operations of the Company and the Company Subsidiaries as
presently conducted.

          (b) Each  Company  Ground  Station  other  than  Very  Small  Aperture
Terminal (VSAT) earth stations (the "VSAT Stations") now operated by the Company
or a Company Subsidiary (a "Major Station") is listed on Schedule 3.14(b),  and,
except as set forth on such  schedule,  with respect to each such Major Station,
the improvements thereto and all components used in connection therewith are (i)
in good  operating  condition  and repair and are  suitable  for their  intended
purposes and (ii)  supported by a back-up,  fuel-powered  electricity  generator
capable  of  generating  power  sufficient  to  meet  the  requirements  of  the
operations  conducted at the Major Station. The  transmission/reception  systems
and  programming and data  broadcasting  systems at each such Major Station have
the  redundancies  that are set forth on Schedule  3.14(b).  The VSAT  Stations,
taken as a whole, are in good operating condition and repair,  ordinary wear and
tear excepted, and are suitable for their intended purposes.

          (c) Set forth on Schedule  3.14(c) are the  following:  (i) a complete
and accurate list, by orbital location,  of each Company Satellite,  (ii) a true
and correct copy of a satellite  loading chart listing each  transponder  on the
Satellite,  along  with the type of  transponder  and the  customer  or group of
related  customers  that have  purchased  services  utilizing  capacity  on such
transponder and the amount of such capacity  allocated to such customer(s),  and
(iii) the most recent "Health Status Report," summarizing all spacecraft related
incidents and anomalies known to the Company as well as the current  status,  to
the best knowledge of the Company, of the subsystems on the Company Satellites.

          (d) Except as set forth on Schedule 3.14(d),  to the best knowledge of
the Company the equipment to provide  tracking,  telemetry and control  services
related  to  each  Satellite  is (i) in good  operating  condition  and  repair,
ordinary wear and tear excepted,  and (ii) not in need of maintenance or repairs
except for ordinary, routine maintenance and repairs.

          (e) Except as set forth on Schedule 3.14(e),  to the best knowledge of
the Company,  no person or entity has  asserted  that it has rights to operate a
spacecraft  in a manner that would  result in  interference  with respect to any
satellite now operated by the Company or any Company Subsidiary or for which the
Company or any Company  Subsidiary  has applied for a permit.  Schedule  3.14(e)
contains a list of all satellite coordination agreements to which the Company or
any Company  Subsidiary are a party,  a summary of all  operational or technical




                                       25

limitations set forth therein, and a summary of all coordination  discussions in
which the Company or the Company Subsidiaries has been engaged in the past three
(3) years with other  persons  or  entities  with  regard to any  Satellite  now
operated by the Company or any  Company  Subsidiary  or for which the Company or
any Company Subsidiary has applied for a permit.

          (f) Schedule 3.14(f) contains a summary,  by orbital location,  of the
status of frequency registration at the International  Telecommunication  Union,
for each Satellite  operated,  or proposed to be operated  during the next three
(3) years, by the Company or any Company  Subsidiary,  including the identity of
the sponsoring administration and frequency bands covered.

     SECTION 3.15.     LABOR RELATIONS.

          Except as set forth in  Schedule  3.15,  Neither  the  Company nor any
Company  Subsidiary is a party to any collective  bargaining  agreement or other

including,  without limitation,  provisions relating to wages, hours, collective
bargaining, safety and health, work authorization, equal employment opportunity,
immigration  and the  withholding  of income taxes,  unemployment  compensation,
worker's  compensation,  employee  privacy and right to know and social security
contributions.

     SECTION 3.16.     ENVIRONMENTAL MATTERS.

          (a) Except as set forth in Schedule  3.16 and except for matters which

Company  Subsidiary is in compliance with all of the terms of such Environmental
Permits and authorizations, and no other Environmental Permits or authorizations

<PAGE>


          (b) Except as set forth in Schedule 3.16 and except for  Environmental
Claims  (as  defined  below)  which  would not have a Company  Material  Adverse
Effect,  there is no  Environmental  Claim  pending or, to the  knowledge of the
Company,  threatened  against or  involving  the  Company or any of the  Company
Subsidiaries   or  against  any  person  or  entity  whose   liability  for  any
Environmental  Claim the Company or any of the Company  Subsidiaries  has or may
have retained or assumed either contractually or by operation of law.

          (c) Except as set forth in Schedule  3.16 and except for matters which

Adverse Effect.

          (b) The execution and delivery of this Agreement by Acquiror does not,

throughout the periods  involved (except as may be noted therein) and subject in

     SECTION 5.7.     ABSENCE OF CERTAIN CHANGES OR EVENTS.

          Except as set forth in Schedule 5.7, since June 30, 1997, Acquiror and

dispute,  damage,  destruction or loss, whether or not covered by insurance,  or
other event of any




                                       34

Material Adverse Effect.

     SECTION 5.8.     ABSENCE OF LITIGATION.

          Except as set forth in Schedule 5.8, as of the date hereof,  there are
(a) no claims,  actions,  suits,  investigations,  or proceedings pending or, to
Acquiror's  knowledge,  threatened  against Acquiror or any Acquiror  Subsidiary
before  any  court,   administrative,   governmental,   arbitral,  mediation  or
regulatory  authority  or body,  domestic or foreign,  that would be  reasonably
likely to have an Acquiror Material Adverse Effect, or that challenge or seek to
prevent, enjoin, alter or materially delay the transactions contemplated hereby,
and (b) no judgments,  decrees, injunctions or orders of any Governmental Entity
or arbitrator outstanding against Acquiror or any Acquiror Subsidiary that would
reasonably be likely to have an Acquiror Material Adverse Effect.

     SECTION 5.9.     LICENSES AND PERMITS; COMPLIANCE WITH LAWS.

          Except as set forth in Schedule  5.9 or  disclosed in the Acquiror SEC
Reports:

          (a) Acquiror and Acquiror Subsidiaries hold all permits,  licenses and
approvals  (none of which has been modified or rescinded and all of which are in
full  force  and  effect)  from all  Governmental  Entities  (collectively,  the
"Acquiror  Permits")  necessary for Acquiror and Acquiror  Subsidiaries  to own,
lease and operate their  respective  properties and to carry on their respective
businesses,   including,  without  limitation,  the  construction,   launch  and
operation  of,  and  transmitting  to  and  from,  each  of the  satellites  and
transponders owned by Acquiror (the "Acquiror  Satellites") and ground stations,
including,   without  limitation,   the  related  broadcasting  facility  assets
consisting of land, building, fixtures, improvements and telemetry, tracking and
control equipment that is owned or leased by Acquiror or an Acquiror  Subsidiary
(each an  "Acquiror  Ground  Station"  and  collectively  the  "Acquiror  Ground
Stations") and the provision of broadcasting or communications services,  except
for  Acquiror  Permits for which the failure to obtain would not have a Acquiror
Material  Adverse  Effect.  Each  of  Acquiror  and  Acquiror  Subsidiaries  has
fulfilled and complied in all material  respects with its obligations under each
of Acquiror Permits owned, held or possessed by it, and no event has occurred or
condition or state of facts exists which  constitutes  or, after notice or lapse
of time or both,  would constitute a breach or default under any Acquiror Permit
and  which  permits  or,  after  notice or lapse of time or both,  would  permit
revocation or termination of any such Acquiror Permit,  and neither Acquiror nor
any Acquiror  Subsidiary  has received or has knowledge of any written notice of
cancellation or default or of any dispute  concerning any Acquiror Permit, or of
any such event,  condition or state of facts that would constitute a default the
effect of 



                                       35
<PAGE>


which would be revocation or termination of such Acquiror  Permit,  in each case
where these would be an Acquiror Material Adverse Effect. If any of the Acquiror
Permits  that has been  issued  prior to the date  hereof is the  subject of any
pending  renewal  application,  Acquiror  is not  aware  of any  reason  why the
Acquiror  Permits  will not be  renewed  in the  ordinary  course  or why any of
Acquiror  Permits  might  be  revoked,  except  in  each  case  where  any  such
non-renewal  or  revocation  would not  individually  or in the  aggregate be an
Acquiror Material Adverse Effect.  Except for rulemaking  proceedings  affecting
the  satellite  industry in general,  no  judgment,  decree,  order or notice of
violation  has been  issued  by the FCC (or  other  Governmental  Entity)  which

would be no Acquiror Material Adverse Effect, (a) no proceedings are pending or,
to Acquiror's knowledge,  threatened in writing, which challenge the validity of
the  ownership  by  Acquiror  and/or any  Acquiror  Subsidiary  of any  material
Acquiror   Intellectual   Property;   (b)  Acquiror  has  no  knowledge  of  any
infringement or infringing use of any material Acquiror Intellectual Property or

transactions  contemplated  hereby,  and no  written  claim has been made by any
third party based upon an allegation of any such infringement;  and (d) material

stipulation by or with any court, arbitrator or administrative agency.

     SECTION 5.12.     MATERIAL CONTRACTS.

          Except as set forth in Schedule 5.12, all agreements filed as exhibits
to Acquiror SEC Reports and each  agreement  that would have been required to be
filed as an exhibit to Acquiror SEC Reports if such  agreement  had been entered
into prior to the date of filing any such Acquiror SEC Report (collectively, the
"Acquiror  Material  Contracts")  are valid and in full  force and effect on the
date hereof except to the extent they have previously expired in accordance with
their terms,  and neither  Acquiror nor any Acquiror  Subsidiary has (or has any
knowledge that any 



                                       37
<PAGE>


party  thereto has) violated any provision of, or committed or failed to perform
any act which with or without notice,  lapse of time or both would  constitute a
default under the  provisions  of, any Acquiror  Material  Contract,  except for
defaults  which would not  reasonably  be expected to have an Acquiror  Material
Adverse Effect.

     SECTION 5.13.     EMPLOYEE BENEFIT PLANS.

          (a)  Each of the  Benefit  Plans  currently  adopted,  maintained  by,
sponsored  in whole or in part by, or  contributed  to by Acquiror or any entity
required to be  aggregated  with  Acquiror  which is a member of the  controlled
group of  corporations  which  includes  Acquiror  within the meaning of Section
414(b) or (c) of the Code (each, an "Acquiror Commonly  Controlled  Entity") for
the benefit of present and former employees or directors of Acquiror and of each
Acquiror  Subsidiary  or their  beneficiaries,  or  providing  benefits  to such
persons in respect of services  provided to any such entity  (collectively,  the
"Acquiror  Benefit  Plans")  intended  to be  "qualified"  within the meaning of
Section 401(a) of the Code has been  determined by the Internal  Revenue Service
to be so qualified and, to Acquiror's  knowledge,  no  circumstances  exist that
could reasonably be expected by Acquiror to result in the revocation of any such
determination.  Each of the Acquiror  Benefit  Plans is in  compliance  with the
applicable  terms of ERISA and the Code and any other applicable laws, rules and
regulations  the  breach  or  violation  of which  could  result  in a  material
liability to Acquiror or any Acquiror Commonly Controlled Entity.

          (b) No Acquiror  Benefit  Plan which is an "employee  pension  benefit
plan," as that term is  defined  in Section  3(2) of ERISA (an  "Acquiror  ERISA
Plan")  which is a defined  benefit  pension plan that is subject to Title IV of
ERISA has any "unfunded  current  liability," as that term is defined in Section
302(d)(8)(A) of ERISA.

          (c) No Acquiror Benefit Plan is a Multiemployer Plan. Neither Acquiror
nor  any  Acquiror  Commonly  Controlled  Entity  has  completely  or  partially
withdrawn from any Multiemployer  Plan. No termination  liability to the Pension
Benefit Guaranty  Corporation or withdrawal  liability to any Multiemployer Plan
that is  material  in the  aggregate  has been or is  reasonably  expected to be
incurred  with  respect to any  Multiemployer  Plan by Acquiror or any  Acquiror
Commonly Controlled Entity.

     SECTION 5.14.     QUALIFICATION OF ACQUIROR.

          Acquiror  is  and  pending  the   Effective   Time  will  be  legally,
technically,  financially and otherwise  qualified under the  Communications Act
and all rules,  regulations and policies of the FCC to acquire,  own and operate
the material  assets and  business of the Company and the Company  Subsidiaries.
Acquiror knows of the existence of no fact that,  under any Acquiror Permits and
present law relating  thereto,  would disqualify  Acquiror from consummating the
Merger within the time



                                       38
<PAGE>


contemplated herein. There are no facts or proceedings which would reasonably be
expected to disqualify  Acquiror under the  Communications Act or otherwise from
acquiring  or  operating  any of the assets and  business of the Company and the
Company  Subsidiaries  or would cause the FCC not to approve the FCC Application
(as  defined  in  Section  7.4(a)).  Acquiror  has no  knowledge  of any fact or
circumstance relating to Acquiror or any of its affiliates that would reasonably
be expected to (a) except as set forth on Schedule 5.14, cause the filing of any
objection  to the FCC  Application,  or (b)  lead  to a  material  delay  in the
processing  by the FCC of the FCC  Application.  No  waiver  of any FCC  rule or
policy is necessary to be obtained for the approval of the FCC Application,  nor
will processing  pursuant to any exception or rule of general  applicability  be
requested or required in connection with the  consummation  of the  transactions
herein.

     SECTION 5.15.     BROKERS.

          No broker,  finder or investment  banker is entitled to any brokerage,
finder's  or  other  fee or  commission  in  connection  with  the  transactions
contemplated by this Agreement based upon  arrangements  made by or on behalf of
Acquiror.

laws; (h) use its commercially  reasonable  efforts to maintain each Key Company

interference is prohibited by FCC Rules or inconsistent with rights accorded the
Company  Satellites  under the  International  Telecommunication  Union's  radio
regulations  and shall  promptly  notify  Acquiror  of any actual or  threatened
interference;  and (j)  proceed  in the  ordinary  course of  business  with all

or any of the Company  Subsidiaries  deems it necessary to take certain  actions

promptly  after  the  date of this  Agreement,  take  all  action  necessary  in
accordance with Delaware Law and its certificate of incorporation  and bylaws to
convene a meeting of the Company's  stockholders  (together with any adjournment
or postponement thereof, the "Stockholders' Meeting"), to approve and adopt this
Agreement and the Merger. As promptly as practicable after  effectiveness of the
Proxy  Registration  Statement,  the  Company  shall  mail the  proxy  statement
included in the Proxy Registration Statement to its stockholders.  The Company's
Board of Directors shall  recommend  approval of the  transactions  contemplated
hereby and shall take all lawful  action to  solicit  from  stockholders  of the
Company proxies in favor of the approval and adoption of this Agreement and this
Merger  (subject to Section 7.10 hereof).  Notwithstanding  the  foregoing,  the
Company  shall not be obligated to mail such proxy  statement  (or, if the proxy
statement has been mailed,  hold the Stockholders  Meeting) until the earlier of
(i) the receipt of the Requisite  Consents under Section 7.14 or (ii) the making
by Acquiror of the election under Section  7.14(b) as to whether to (A) waive as
a condition of Closing (Section  8.2(f)) that the Requisite  Consents shall have

          (a) As promptly as  practicable  after the  execution  and delivery of
this  Agreement,  Acquiror,  Merger  Sub  and  the  Company  shall  prepare  all
appropriate  applications  for FCC consent,  and such other  documents as may be
required,  with  respect to the  transfer  of control of the Company to Acquiror
(collectively,  the "FCC Application").  As promptly as practicable  thereafter,
Acquiror and Merger Sub shall deliver to the Company their respective  completed
portions of the FCC Application. As promptly as practicable,  but not later than
twenty-one  (21) calendar  days after the date hereof,  the Company and Acquiror

Sub and the Company shall use their reasonable best efforts to prosecute the FCC
Application  in good faith and with due  diligence  in order to obtain  such FCC

for any reason within the initial  effective  period of the granting of approval
by the FCC of the FCC  Application,  and neither  Acquiror nor the Company shall
have terminated this Agreement pursuant to Section 9.1, Acquiror and the Company
shall jointly  request one or more  extensions  of the effective  period of such
grant.  No party hereto shall  knowingly  take, or fail to take,  any action the
intent or reasonably  anticipated  consequence of which action or failure to act
would be to cause the FCC not to grant approval of the FCC Application.

          Acquiror and the Company shall consult with each other before  issuing
any press release or otherwise making any public  statements with respect to the
transactions  contemplated  hereunder and shall not issue any such press release
or make any such public statement prior to such  consultation,  except as may be
required by law or any listing  agreement with the NYSE, or the Nasdaq  National

     SECTION 7.7.     INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.

          (a) The  certificate  of  incorporation  and  bylaws of the  Surviving
Corporation  shall contain the provisions  with respect to  indemnification  set
forth in the certificate of incorporation  and bylaws of the Company on the date

modified  for a period of six (6) years after the  Effective  Time in any manner
that would  adversely  affect the rights  thereunder  of persons who at any time
prior to the Effective Time were identified as prospective indemnitees under the
certificate of  incorporation  or bylaws of the Company in respect of actions or
omissions  occurring  at or  prior to the  Effective  Time  (including,  without
limitation,  the  transactions  contemplated  by this  Agreement),  unless  such
modification is required by applicable law.



                                       46
<PAGE>


          (b) From and  after  the  Effective  Time,  Acquiror  shall  cause the
Surviving  Corporation  to  indemnify,  defend and hold harmless the present and
former  officers,  directors  and  employees  of the  Company  and  the  Company
Subsidiaries  (collectively,  the  "Indemnified  Parties")  against  all losses,
expenses,  claims,  damages,  liabilities or amounts that are paid in settlement
of, with the  approval of Acquiror  (which  approval  shall not be  unreasonably
withheld),  or otherwise in connection with, any claim, action, suit, proceeding
or  investigation  (a "Claim"),  based in whole or in part on the fact that such
person is or was such a director, officer or employee and arising out of actions
or omissions  occurring at or prior to the Effective  Time  (including,  without
limitation,  the transactions  contemplated by this Agreement),  in each case to
the fullest  extent  permitted  under  Delaware  Law (and shall pay  expenses in
advance  of the  final  disposition  of any such  action or  proceeding  to each
Indemnified  Party to the fullest  extent  permitted  under  Delaware  Law, upon
receipt  from  the  Indemnified  Party  to whom  expenses  are  advanced  of the
undertaking  to repay such advances  contemplated  by Section 145(e) of Delaware
Law).

          (c) Without limiting the foregoing,  in the event any Claim is brought
against any  Indemnified  Party  (whether  arising before or after the Effective
Time)  after the  Effective  Time:  (i) the  Indemnified  Parties may retain its
regularly engaged independent legal counsel as of the date of this Agreement, or
other  independent  legal counsel  satisfactory to them provided that such other
counsel shall be reasonably  acceptable to Acquiror,  (ii) Acquiror  shall cause
the  Surviving  Corporation  to pay all  reasonable  fees and  expenses  of such
counsel  for  the  Indemnified  Parties  promptly  as  statements  therefor  are
received,  and (iii) Acquiror  shall cause the Surviving  Corporation to use its
reasonable  efforts  to  assist  in the  vigorous  defense  of any such  matter,
provided that neither the Acquiror nor the Surviving Corporation shall be liable
for any  settlement  of any  Claim  effected  without  the  written  consent  of
Acquiror,  which consent shall not be  unreasonably  withheld.  Any  Indemnified
Party  wishing to claim  indemnification  under this Section 7.7,  promptly upon
learning of any such Claim, shall notify the Acquiror and Surviving  Corporation
(although the failure so to notify the Acquiror and Surviving  Corporation shall
not relieve the Acquiror and Surviving  Corporation from any liability which the
Acquiror and Surviving  Corporation  may have under this Section 7.7,  except to
the extent such failure prejudices the Acquiror and Surviving Corporation),  and
shall  deliver  to  the  Acquiror  and  Surviving  Corporation  the  undertaking
contemplated  by Section  145(e) of Delaware Law. The  Indemnified  Parties as a
group may retain one law firm (in addition to local  counsel) to represent  them
with respect to each such matter unless there is, under applicable  standards of
professional  conduct (as reasonably  determined by counsel to such  Indemnified
Parties) a conflict on any significant  issue between the position of any two or
more of such Indemnified  Parties,  in which event, an additional counsel as may
be required may be retained by such Indemnified Parties.

          (d) Acquiror  shall cause to be maintained in effect for not less than
six (6) years after the Effective  Time the current  policies of directors'  and
officers' liability  insurance and fiduciary  liability insurance  maintained by
the Company  with  respect to matters  occurring  prior to the  Effective  Time;
provided,  however,  that (i)  Acquiror  may  substitute  therefor  policies  of
substantially  the  same  coverage  containing  terms  and  conditions  that are
substantially  the same for the  Indemnified  Parties to the  extent  reasonably
available and (ii) Acquiror  shall not be required to pay an annual  premium for
such  insurance  in  excess of two  hundred  percent  (200%) of the last  annual
premium  paid  prior  to the  date of this  Agreement,  but in such  case  shall
purchase as much coverage as possible for such amount.

          (e) This  Section  7.7 is intended to be for the benefit of, and shall
be enforceable by, the Indemnified  Parties referred to herein,  their heirs and
personal representatives and shall be binding on Acquiror and Merger Sub and the
Surviving  Corporation  and their  respective  successors and assigns.  Acquiror
hereby  guarantees  the  Surviving  Corporation's  obligations  pursuant to this
Section 7.7.

     SECTION 7.8.     EMPLOYEE BENEFITS MATTERS.

          (a) Acquiror shall cause the Surviving Corporation to provide employee
benefits under plans, programs and arrangements,  which, in the aggregate,  will

which are no less favorable,  in the aggregate,  than those provided pursuant to
the plans,  programs and  arrangements of the Company in effect and disclosed to
Acquiror on the date  hereof;  provided,  however,  that  nothing  herein  shall
interfere  with the  Surviving  Corporation's  right or  obligation to make such
changes to such plans, programs or arrangements as are necessary to conform with
applicable law.

          (b) Acquiror acknowledges and agrees that prior to the Effective Time,
the  Company  will take all such  actions as may be  necessary  to cause (i) all
participants to become fully vested in their benefits under the Company's 401(k)
Plan, and (ii) employer  contributions  to be made with respect to periods prior
to the  Effective  Time to the  Company's  401(k)  Plan to the extent  that such
contributions  would be made if the participants were employed by the Company on
the last day of the calendar year in which the Closing occurs.

     SECTION 7.9.     FURTHER ACTION; COMMERCIALLY REASONABLE EFFORTS.

          (a) Each of the parties shall use all commercially  reasonable efforts
to take, or cause to be taken,  all appropriate  action,  and do, or cause to be
done,  all  things  necessary,  proper or  advisable  under  applicable  laws or
otherwise to consummate and make effective the transactions contemplated by this
Agreement as promptly as practicable,  including,  without limitation, using all
its commercially reasonable efforts to obtain all licenses,  permits,  consents,
approvals,  authorizations,  qualifications and orders of Governmental  Entities
and parties to

<PAGE>


contracts  with the Company and Acquiror as are necessary  for the  transactions
contemplated  herein.  In case at any time after the Effective  Time any further
action is necessary  or  desirable to carry out the purposes of this  Agreement,
the proper  officers and directors of each party to this Agreement shall use all
commercially reasonable efforts to take all such action.

          (b) During the  Interim  Period,  each of the parties  shall  promptly
notify the other in writing of any pending or, to the  knowledge  of such party,
threatened action, proceeding or investigation by any Governmental Entity or any
other person (i) challenging or seeking damages in connection with the Merger or
the  conversion of the Capital Stock into the Merger  Consideration  pursuant to
the Merger or (ii)  seeking to  restrain  or prohibit  the  consummation  of the
Merger or  otherwise  limit the right of  Acquiror  to own or operate all or any
portion of the business or assets of the Company.

          (c) Each  party  shall  use its  commercially  reasonable  efforts  to
refrain from taking any action,  or entering into any  transaction,  which would
cause any of its representations or warranties contained in this Agreement to be
untrue or result in a breach of any covenant made by it in this Agreement.

     SECTION 7.10.    NEGOTIATION WITH OTHERS.

          (a) Neither the Company nor any Company Subsidiary shall,  through any
officer,  director,  employee,  representative,  agent  or  direct  or  indirect
stockholder  of the Company or any Company  Subsidiary,  directly or indirectly,
take any action to (i)  encourage,  initiate  or solicit the  submission  of any
proposal that constitutes an Acquisition Proposal, (ii) enter into any agreement
with respect to or accept any Acquisition Proposal; or (iii) encourage, initiate
or solicit the making of any proposal  that  constitutes  or may  reasonably  be
expected to lead to, an Acquisition  Proposal;  provided,  however, that nothing
contained  in this Section  7.10 shall  prohibit  the  Company,  or its Board of
Directors,  from making any disclosure to its stockholders that, in the judgment
of its Board of  Directors in  accordance  with,  and based upon,  the advice of
independent legal counsel, is required under applicable law.

          For purposes of this  Agreement,  "Acquisition  Proposal" means any of
the following:  (i) any merger,  consolidation or similar transaction  involving
the Company, (ii) any sale, lease or other disposition directly or indirectly by
merger,  consolidation,  share exchange or otherwise of assets of the Company or
Company Subsidiaries  representing 20% or more of the consolidated assets of the
Company  and  the  Company  Subsidiaries,   (iii)  any  issue,  sale,  or  other
disposition  of  securities  (or  options,  rights or warrants to  purchase,  or
securities  convertible into or exchangeable for, such securities)  representing
20% or more of the voting power of the Company, or (iv) any transaction in which
any person shall acquire  beneficial  ownership (as such term is defined in Rule
13d-3 under the Exchange Act), or the 



                                       49
<PAGE>


right to acquire  beneficial  ownership  or any "group" (as such term is defined
under the Exchange  Act) shall have been formed which  beneficially  owns or has
the right to  acquire  beneficial  ownership  of 35% or more of the  outstanding
Common Stock.

          (b)  Notwithstanding  Section  7.10(a),  the Board of Directors of the
Company,  in the  exercise  of and  as  required  by  its  fiduciary  duties  as
determined  in good faith by the Board of Directors of the Company in accordance
with and based upon the advice of  independent  legal  counsel,  may (i) furnish
information  to, or enter into  discussions  with,  a third  party who makes (or
requests  information  for the  purpose  of  making)  an  unsolicited  bona fide
Acquisition   Proposal,   if  such  third   party   executes   and   delivers  a
confidentiality  agreement  in  reasonably  customary  form on  terms  not  more
favorable  to such  person  or  entity  than the  terms  of the  Confidentiality
Agreement,  or (ii) withdraw or modify in any manner  adverse to the Acquiror or
propose publicly to withdraw or modify in any manner adverse to the Acquiror the
approval or  recommendation  by such Board of Directors or such committee of the
Merger or this Agreement, if and only to the extent that the Board of Directors:
(A) believes in good faith,  based on the advice of its  financial  advisor that
such  Acquisition  Proposal would, if consummated,  result in a transaction more
favorable from a financial point of view to all stockholders of the Company, and
(B)  determines  in good faith,  based  upon,  to the extent  legal  matters are
relevant to such fiduciary  duties,  a reasoned  written  opinion of its outside
legal  counsel,  that such action is necessary  for the directors to comply with
their fiduciary  duties to the stockholders  under applicable  Delaware Law; and
(C) in the event  that the  Board of  Directors  of the  Company  determines  to
withdraw  or  modify  in a  manner  adverse  to the  Acquiror  its  approval  or
recommendation  of the Merger or this  Agreement,  it shall do so only at a time
that is after the  second  business  day  following  Acquiror's  receipt  of the
written  notice in accordance  with the next  succeeding  sentence.  The Company
shall promptly notify Acquiror in writing of any such request for information or
Acquisition   Proposal,   specifying   reasonable  details  of  any  inquiry  or
Acquisition   Proposal   (including  the  identity  of  the  entity  making  the
Acquisition  Proposal,  to  the  extent  not  prohibited  by  a  confidentiality
agreement in effect on the date hereof),  and shall keep Acquiror informed as to
the status of any discussions or negotiations.

     SECTION 7.11.    STOCK MERGER LISTING.

          Acquiror shall use all reasonable efforts to cause the Acquiror Shares
to be issued  pursuant to this Agreement to be approved for listing on the NYSE,
subject to official notice of issuance, prior to the Closing Date.

     SECTION 7.12.    BLUE SKY.

          Acquiror shall use  reasonable  efforts to obtain prior to the Closing
Date any  necessary  blue sky  permits  and  approvals  required  to permit  the



                                       50
<PAGE>

distribution  of the shares of Acquiror  Shares to be issued in accordance  with
the provisions of this Agreement.

     SECTION 7.13.    AFFILIATE AGREEMENTS.

          At least 30 days  prior  to the  Effective  Time,  the  Company  shall
deliver  to  Acquiror  a  letter  identifying  all  persons  who  may be  deemed
affiliates  of the Company  under Rule 145 of the  Securities  Act.  The Company
shall  use all  reasonable  efforts  to  deliver  or  cause to be  delivered  to
Acquiror,  from each  person  who will be  identified  in such  letter,  written
agreements (collectively,  the "Affiliate Agreements") substantially in the form
attached to this Agreement as Exhibit A.

     SECTION 7.14.    CONSENT SOLICITATION AND SUPPLEMENTAL INDENTURE.

          (a) As promptly as  practicable  after the  execution  and delivery of
this  Agreement,  the Company shall  prepare,  in  consultation  with  Acquiror,
written  materials to commence a solicitation  (the "Consent  Solicitation")  of
consents to amendments to, or waivers under, the Indentures, dated as of January
31,  1997,  for the Senior  Notes (as  defined  below)  among the  Company,  the
subsidiaries  of the Company  named  therein as  Guarantors,  and Bankers  Trust
Company,  as Trustee  (the  "Indentures"),  from the  Holders (as defined in the
Indentures)  of not less than a majority in  aggregate  principal  amount of the
Senior Notes in order to obtain a waiver of the  Company's  compliance  with the
covenants set forth in Section 5.01 (iii) and Section 5.01(iv) of the Indentures
in  connection  with the  consummation  of the Merger  (the  consents  from such
Holders,   the  "Requisite   Consents").   The  Company  will   distribute  such
solicitation  materials to the Holders as promptly as  practicable  and will use
commercially  reasonable  efforts  to obtain  such  consents,  provided  that no
consideration  shall be offered to the Holders of the Senior  Notes  pursuant to
the Consent  Solicitation  for rendering their consents  thereunder  without the
prior written approval of Acquiror.  At the Effective Time, Acquiror shall cause
the Surviving  Corporation  to execute and deliver to the Trustee a supplemental
indenture  pursuant to, and  satisfying  the  requirements  of, the  Indentures.
"Senior  Notes" shall mean the Company's  11.25% Senior Notes Due 2007 and 12.5%
Senior Discount Notes Due 2007.

          (b) If, within forty (40) days after the date the Company  distributes
the Consent  Solicitation to the Holders (the "Solicitation  Termination Date"),
the Company has not received the Requisite  Consents,  Acquiror shall elect (the
"Acquiror  Election")  either to (i) commence an exchange  offer as set forth in
Section 7.15, or (ii) waive as a condition of Closing  (Section 8.2(f)) that the
Requisite  Consents  shall  have been  obtained.  Acquiror  shall  exercise  the
Acquiror  Election by delivering  written  notice of Acquiror's  election to the
Company  within two business days after the  Solicitation  Termination  Date. If
Acquiror fails to timely and properly exercise the Acquiror Election within such
two business  days,  Acquiror shall be deemed to have waived the delivery of the
Requisite  Consents as a closing




                                       51
<PAGE>

condition. The Company agrees to provide the Acquiror with written notice of the
date of the  Solicitation  Termination Date at least five business days prior to
the occurrence of such Solicitation Termination Date.

     SECTION 7.15.    THE EXCHANGE OFFER.

          (a) Terms of the Exchange  Offer.  As promptly as practicable  (and in
any event within five business  days) after  Acquiror's  delivery of an Acquiror
Election  pursuant to Section  7.14(b)  hereof  electing to commence an exchange
offer,  Acquiror shall announce its election to commence  (within the meaning of
Rule 14d-2 under the Exchange Act) an irrevocable  exchange offer (the "Exchange
Offer") to acquire all of the issued and outstanding  shares of Capital Stock in
exchange  for the number of fully paid and  nonassessable  Acquiror  Shares (the
"Exchange  Consideration")  equal to the number that would be issued pursuant to
the Merger (except that the Averaging  Period would end on the tenth Trading Day
immediately  prior to the closing  date for the Exchange  Offer),  and with such
other terms and  conditions  which make the Exchange Offer at least as favorable
to the  holders  of the  issued and  outstanding  shares of  Capital  Stock (and
options,  warrants and other rights to purchase  Capital Stock) as the terms and
conditions  of the Merger,  as set forth  herein.  Acquiror  shall  conduct such
Exchange Offer in accordance  with this Section 7.15 and applicable  law. To the
extent practicable in the context of the Exchange Offer the parties hereto shall
seek to provide  to each other all of the  benefits  of the  provisions  of this
Agreement.  Acquiror  hereby agrees that within two business days  following the
later to occur of the  expiration of the minimum  statutory  period during which
exchange  offers must remain open and all Exchange Offer  Conditions (as defined
below) having been  satisfied or waived,  Acquiror shall accept for exchange all
shares of Capital Stock tendered and promptly  issue the Exchange  Consideration
to the  holders of Capital  Stock who shall have  tendered  their  shares in the
Exchange Offer.

          The obligation of Acquiror to consummate the Exchange Offer once it is
commenced  and to accept  for  exchange  the shares of  Capital  Stock  tendered
pursuant to the Exchange Offer shall be subject only to the following conditions
(the "Exchange Offer  Conditions"):  (i) the holders of the outstanding  Capital
Stock representing at least 50.1% of the voting power of the Capital Stock (on a
fully  diluted  basis) as of the date the Exchange  Offer is commenced  (and all
shares of Capital  Stock held by Acquiror,  each  Acquiror  Subsidiary  and each
affiliate  thereof shall be deemed to be included  within such 50.1%)  accepting
the Exchange Offer,  (ii) the  resignations of the Company's  directors prior to
consummation  of the Exchange Offer and (iii) the  satisfaction of the following
conditions  precedent sections of this Agreement (to the extent applicable to an
exchange offer): 8.1(b), 8.1(c), 8.1(d), 8.1(e), 8.2(a), 8.2(b), 8.2(c), 8.2(d),
8.2(e).  Acquiror expressly  reserves the right to waive any such condition,  to
increase the  consideration  payable in the Exchange Offer and to make any other
changes  in the  terms and  conditions  of the  Exchange  Offer  which  make the
Exchange Offer more favorable to the holders of the




                                       52
<PAGE>

issued  and  outstanding  shares of  Capital  Stock than the Merger and than the
requirements  for the  Exchange  Offer set  forth  herein.  Notwithstanding  the
foregoing, no change may be made which (i) causes the Exchange Offer not to meet
the  requirements  of this Section 7.15,  (ii) decreases or changes the Exchange
Consideration  to be paid in the  Exchange  Offer,  (iii)  reduces the number of
shares of Capital  Stock  sought to be purchased  in the  Exchange  Offer,  (iv)
imposes  conditions  to the  Exchange  Offer other than those  permitted by this
Section  7.15,  (v) extends the  expiration  date of the Exchange  Offer or (vi)
otherwise  alters  or  amends  any  term of the  Exchange  Offer  in any  manner
materially adverse to the holders of shares of Capital Stock; provided, however,
that subject to the right of the parties to terminate this Agreement pursuant to
Section  9.1,  the  Exchange  Offer may be extended for any period to the extent
required to satisfy any Exchange  Offer  Condition or to the extent  required by
law or by any rule,  regulation,  interpretation  or  position of the SEC or the
staff  thereof,  so long as the Exchange  Offer shall not extend beyond June 30,
1998. Acquiror shall not acquire less than all of the shares of Capital Stock or
other securities that are tendered pursuant to the Exchange Offer.

          (b) Exchange Offer  Documents.  As promptly as  practicable  after the
election  by the  Acquiror to commence of the  Exchange  Offer,  Acquiror  shall
convert  the Proxy  Registration  Statement  into and shall  file with the SEC a
registration  statement  (together  with the  amendments  thereof or supplements
thereto,  the  "Exchange   Registration   Statement")  in  connection  with  the
registration  under  the  Securities  Act of the  Acquiror  Shares  to be issued
pursuant to the Exchange  Offer.  Acquiror shall use all  reasonable  efforts to
have or cause  the  Exchange  Registration  Statement  to  become  effective  as
promptly as  practicable.  As promptly as  practicable  (and in any event within
five  business  days)  after the  Exchange  Registration  Statement  has  become
effective,   Acquiror  shall  commence  the  Exchange   Offer.  As  promptly  as
practicable on the date of commencement  of the Exchange  Offer,  Acquiror shall
file  with  the  SEC  a  Tender  Exchange  Offer  Statement  on  Schedule  14D-1
promulgated under the Exchange Act (together with all amendments and supplements
thereto, the "Schedule 14D-1") with respect to the Exchange Offer, and take such
steps as are reasonably necessary to cause the Exchange Offer to be disseminated
to the  holders of shares of  Capital  Stock as and to the  extent  required  by
applicable federal securities laws. The Schedule 14D-1 shall contain an offer to
exchange  (the  "Offer  to  Exchange")  and  forms  of  the  related  letter  of
transmittal  and any related  summary  advertisement  (the Schedule  14D-1,  the
Exchange Registration Statement,  the Offer to Exchange and such other documents
as may be  required  by the  Exchange  Act,  the  NYSE,  the  NASD or any  other
applicable  laws,  rules  or  regulations,  together  with  all  amendments  and
supplements  thereto,  the "Exchange Offer  Documents").  Acquiror shall use its
best  efforts  to  distribute  such  Exchange  Offer  Documents,  and any  other
documents  required by law or this Agreement to all holders of shares of Capital
Stock,  in accordance with the  requirements of this Section 7.15.  Acquiror and
the Company shall correct  promptly any information  provided by any of them for

                                       53
<PAGE>


Exchange Offer Documents if such information  shall contain any untrue statement
of a material  fact or omit to state any  material  fact  required  to be stated
therein or necessary in order to make the statements contained therein, in light
of the  circumstances  under which they were made, not misleading,  and Acquiror
shall use all reasonable  efforts to cause the Schedule 14D-1 as so corrected to
be filed with the SEC and the other Exchange Offer  Documents as so corrected to
be  disseminated  to holders of shares of Capital Stock,  in each case as and to
the extent required by applicable federal securities laws and this Section 7.15.
The Company and its counsel  shall be given a reasonable  opportunity  to review
and comment on the Exchange Offer  Documents prior to their being filed with the
SEC,  and  Acquiror  will provide the Company and its counsel with copies of any
written  comments that Acquiror  receives from the SEC or its staff with respect
to the Exchange Offer Documents promptly after receipt of any such comments.

          (c) Stock  Options.  The  Exchange  Offer will extend to all shares of
Capital  Stock which may be issued as a result of the  exercise  of  outstanding
options,  warrants and other rights to purchase or acquire  Capital  Stock,  and
will involve  assumption  of other  options,  warrants  and rights,  to the same
extent as required with respect to the Merger under Section 2.3.

          (d) Company  Recommendation.  On the date the Schedule  14D-1 is filed
with the SEC, the Company shall file with the SEC a  Solicitation/Recommendation
Statement on Schedule  14D-9  promulgated  under the Exchange Act (together with
all amendments and supplements  thereto,  the "Schedule  14D-9")  containing the
recommendation  of the Board of Directors of the Company for the stockholders of
the  Company to accept  the  Exchange  Offer,  except to the extent the Board of
Directors would be permitted to alter its  recommendation  under Section 7.10(b)
with respect to the Merger,  and shall take such steps as are necessary to cause
the Schedule 14D-9 to be  disseminated to the holders of shares of Capital Stock
as and to the extent required by the NASD or any other  applicable  laws,  rules
and regulations,  including,  without limitation,  applicable federal securities
laws. The Company and Acquiror shall amend or correct  promptly any  information
provided  by any of them for use in the  Schedule  14D-9 which shall have become
false or misleading, and the Company shall take all steps necessary to cause the
Schedule  14D-9  as so  amended  or  corrected  to be  filed  with  the  SEC and
disseminated  to holders of shares of Capital Stock,  in each case as and to the
extent required by applicable federal securities laws.  Acquiror and its counsel
shall be given a  reasonable  opportunity  to review and comment on the Schedule
14D-9  prior to its being  filed  with the SEC,  and the  Company  will  provide
Acquiror  and its counsel with copies of any written  comments  that the Company
receives from the SEC or its staff with respect to the Schedule  14D-9  promptly
after receipt of any such comments.

          (e)  Stockholder  List. In  connection  with the Exchange  Offer,  the
Company shall cause the Company's  transfer agent to furnish  Acquiror  promptly



                                       54
<PAGE>

with mailing labels  containing the names and addresses of all record holders of
shares of Capital Stock and with security position listings of shares of Capital
Stock held in stock  depositories,  each as of a recent date,  together with all
other  available  listings and computer files  containing  names,  addresses and
security  position listings of record holders and beneficial owners of shares of
Capital  Stock.   The  Company  shall  furnish  Acquiror  with  such  additional
information,  including,  without  limitation,  updated  listings  and  files of
stockholders,  mailing  labels and  security  position  listings  and such other
assistance as Acquiror or its agents may reasonably request in communicating the
Exchange  Offer to record and  beneficial  holders  of shares of Capital  Stock.
Subject to the  requirements  of the Securities Act, the Exchange Act, the NYSE,
the NASD and any other  applicable  laws,  rules or regulations,  and except for
such steps as are necessary to disseminate  the Exchange Offer Documents and any
other documents  necessary to consummate the  transactions  contemplated by this
Agreement,  Acquiror shall hold in confidence the information  contained in such
labels,  listings and files,  shall use such information only in connection with
the transactions contemplated by this Agreement, and, if this Agreement shall be
terminated  in  accordance  with  Section 11,  shall  deliver to the Company all
copies of, and any extracts or summaries  from, such  information  then in their
possession or control.

          (f)  Cooperation.  In connection with the Exchange Offer,  the Company
will furnish Acquiror with such  information  (which will be treated and held in
confidence by Acquiror except to the extent required to be disclosed pursuant to
the  Exchange  Offer  or this  Agreement)  and  assistance  as  Acquiror  or its
representatives may reasonably request in connection with the preparation of the
Exchange Offer and communicating the Exchange Offer to the record and beneficial
holders of shares of Capital Stock.

          (g) Subsequent  Merger.  In the event that the Requisite  Consents are
obtained  following  commencement of the Exchange Offer,  Acquiror will continue
with  the  Exchange  Offer  pursuant  to this  Section  and  promptly  following
consummation of the Exchange Offer Acquiror will cause the Merger to occur, with
the Exchange Ratio equal to the exchange ratio applicable to the Exchange Offer.
Acquiror  will  make all  requisite  filings  in  connection  with  the  Merger,
including the preparation and  distribution of a registration  statement and any
required information statement. If the Requisite Consents are obtained after the
Solicitation  Termination  Date but  prior to the  time  the  Exchange  Offer is
commenced,  Acquiror  shall  either  proceed as set forth in this  paragraph  or
abandon the Exchange  Offer and (by written  notice to the Company)  restore the
obligations  of the  parties  with  respect to the  Merger,  fully as though the
Requisite  Consents  had been  obtained  prior to  commencement  of the Exchange
Offer.

     SECTION 7.16.    CONTROL OF ACQUIROR AND THE COMPANY.

          During the Interim  Period,  control of the  operations of the Company
and the  Company's  Subsidiaries  shall  remain  with the Company and control of
Acquiror and Acquiror  Subsidiaries shall remain with Acquiror.  Acquiror agrees
that  neither  it nor any of  Acquiror's  Subsidiaries  shall  control,  direct,
supervise,  or attempt to control,  direct or supervise,  the  operations of the
Company during this period. Likewise, the parties agree that neither the Company
nor any of the Company's  Subsidiaries  shall  control,  direct,  supervise,  or
attempt to control,  direct or  supervise  Acquiror  during the Interim  Period.
Notwithstanding  anything in this Agreement to the contrary,  no action shall be
taken  hereunder  constituting  an  assignment  or transfer of control of an FCC
license,  permit,  authorization  or application  requiring the prior consent or
approval of the FCC without first obtaining such consent or approval.

     SECTION 7.17.    PRIVATE LETTER RULING.

          As promptly as  practicable,  Acquiror and the Company  shall  jointly
seek (including  through the filing of an appropriate  request) a private letter
ruling from the Internal  Revenue  Service under Section 367(a) of the Code that
the Merger  will be  respected  for  purposes  of  Section  367(a) as a tax-free
reorganization  under Section 368(a) of the Code (the "Private Letter  Ruling").
Acquiror  agrees  to  use  commercially   reasonable   efforts  to  satisfy  any
requirements  identified  by the  Internal  Revenue  Service as a  condition  to
receipt of such Private Letter Ruling. Following receipt (or internal assurances
of receipt by the staff of the Internal Revenue Service, as notified to Acquiror
in writing by one or more of the  representatives  of  Acquiror  or the  Company
assisting in the seeking of the Private  Letter  Ruling) of such Private  Letter
Ruling,  Acquiror  shall not,  and shall not permit  Merger Sub or any  Acquiror
Subsidiaries to,  intentionally  take, fail to take, or cause to be taken or not
taken any action within its control that (without  regard to any action taken or
agreed to be taken by the Company or any of its affiliates) would disqualify the
Merger as a  "reorganization"  within the meaning of Section 368(a) of the Code.
Nothing contained in this Section 7.17 shall be construed to require Acquiror to
incur substantial tax detriments or substantial direct expenses.

                                  ARTICLE VIII.

                               CLOSING CONDITIONS

declared effective by the SEC under the Securities Act. No stop order suspending
the effectiveness of such  registration  statement shall have been issued by the
SEC and no  proceedings  for that purpose  shall have been  initiated or, to the
knowledge of Acquiror, the Company or the Stockholders, threatened by the SEC.

          (c) No Order.  No  Governmental  Entity or federal  or state  court of
competent  jurisdiction  shall have enacted,  issued,  promulgated,  enforced or
entered any  statute,  rule,  regulation,  executive  order,  decree,  judgment,
injunction or other order (whether temporary,  preliminary or permanent), in any
case which is in effect and which  prevents  or  prohibits  consummation  of the
Merger or any  other  transactions  contemplated  in this  Agreement;  provided,
however,  that the parties shall use their  reasonable best efforts to cause any
such decree, judgment, injunction or other order to be vacated or lifted.

          The  obligations  of Acquiror  and Merger Sub to effect the Merger and
the other  transactions  contemplated  in this  Agreement  (except the Principal
Stockholder Agreement) are also subject to the following conditions,  any or all
of which may be waived by Acquiror, in whole or in part, to the extent permitted
by applicable law:

          (a) Representations and Warranties. The representations and warranties
of the Company made in this Agreement shall be true and correct when made and on
and as of the Effective Time with the same effect as though such representations
and  warranties  had  been  made on and as of the  Effective  Time  (except  for
representations  and warranties that speak as of a specific date or time,  which
need only be true and correct as of such date or time), except where the 




                                       57
<PAGE>

failure  of  such  representations  and  warranties  to be so true  and  correct
(without  giving  effect  to any  limitation  as to  "materiality"  or  "Company
Material  Adverse  Effect" set forth  therein) does not have a Company  Material
Adverse  Effect.  Acquiror  shall  have  received  a  certificate  of the  Chief
Executive Officer or Chief Financial Officer of the Company to that effect.

          (b)  Agreements  and  Covenants.  The  agreements and covenants of the

Application,  without conditions,  qualifications or other restrictions that are
likely to have an Acquiror Material Adverse Effect or a Company Material Adverse
Effect  immediately after the Closing Date. As used in this Agreement,  the term
"Final Order" means an order,  action or decision of a Governmental  Entity that
has not been  reversed,  stayed or enjoined  and as to which the time to appeal,
petition for  certiorari  or seek  reargument  or  rehearing  or  administrative
reconsideration  or review has  expired  and as to which no appeal,  reargument,
petition  for  certiorari  or  rehearing  or  petition  for  reconsideration  or
application  for review is pending or as to which any right to appeal,  reargue,
petition  for  certiorari  or rehearing  or  reconsideration  or review has been
waived  in  writing  by each  party  having  such a  right  or,  if any  appeal,
reargument,  petition for certiorari or rehearing or  reconsideration  or review
thereof has been  sought,  the order or judgment of the court or agency has been
affirmed by the highest  court (or the  administrative  entity or body) to which
the  order  was   appealed  or  from  which  the   argument  or   rehearing   or
reconsideration  or review was sought,  or certiorari  has been denied,  and the
time to take any further appeal or to seek  certiorari or further  reargument or
rehearing, or reconsideration or review, has expired.

          (d) Other Satellite Approvals. Each Governmental Entity other than the
FCC that has issued to the  Company or any of the Company  Subsidiaries  (i) any
Company  Permit with respect to the  operation of or  transmission  to or from a
Company  Satellite or a Company Ground Station that  communicates with a Company
Satellite,  or  (ii)  any  Company  Permit  with  respect  to the  provision  of
broadcasting or communications services shall have, where required by applicable
law, approved the transfer of control or assignment,  as applicable, of all such
Company  Permits as a result of the Merger without any material  qualifications,
restrictions  or limitations  and such approval shall have become a Final Order,
except where the failure to obtain such approvals would not,  individually or in
the aggregate, have a Company Material Adverse Effect.

                  (e) Other  Approvals.  All  consents,  waivers,  approvals and
authorizations  required to be obtained,  and all filings or notices required to
be



                                       58
<PAGE>

made,  by  the  Company  and  the  stockholders  prior  to  consummation  of the
transactions  contemplated  in this Agreement  shall have been obtained from and
made with all required Governmental Entities,  other than those that the failure
to be filed,  expired  or  obtained  would not have a Company  Material  Adverse
Effect.

          (f) Requisite Consents. Subject to waiver pursuant to Section 7.14(b),
the Requisite Consents shall have been obtained.


     SECTION 8.3.     ADDITIONAL CONDITIONS TO OBLIGATIONS OF THE COMPANY.

          The  obligations  of the  Company  to effect  the Merger and the other
transactions  contemplated in this Agreement  (except the Principal  Stockholder
Agreement) are also subject to the following  conditions any or all of which may
be  waived by the  Company,  in whole or in part,  to the  extent  permitted  by
applicable law:

          (a) Representations and Warranties. The representations and warranties
of Acquiror and Merger Sub made in this Agreement shall be true and correct when
made and on and as of the  Effective  Time with the same  effect as though  such
representations  and  warranties  had been made on and as of the Effective  Time
(except for  representations  and warranties that speak as of a specific date or
time, which need only be true and correct as of such date or time), except where
the failure of such  representations  and  warranties  to be so true and correct
(without  giving  effect to any  limitation  as to  "materiality"  or  "Acquiror
Material  Adverse Effect" set forth therein) does not have an Acquiror  Material
Adverse  Effect.  The Company  shall have  received a  certificate  of the Chief
Executive Officer or Chief Financial Officer of Acquiror to that effect.

          (b) Agreements and Covenants. The agreements and covenants of Acquiror
and Merger Sub required to be performed  on or before the  Effective  Time shall
have been performed in all material respects.  The Company shall have received a
certificate  of the  Chief  Executive  Officer  or Chief  Financial  Officer  of
Acquiror to that effect.

          (c) FCC  Approval.  The FCC shall have  granted by Final Order the FCC

                                       59
<PAGE>


Governmental Entities, other than those that the failure to be filed, expired or
obtained would not have an Acquiror Material Adverse Effect.

                                   ARTICLE IX.

                       TERMINATION, AMENDMENT AND WAIVER

     SECTION 9.1.     TERMINATION.

          This  Agreement  may be  terminated at any time prior to the Effective
Time,  whether  before or after approval of this Agreement and the Merger by the
stockholders of the Company:

          (a) by mutual written consent of each of Acquiror and the Company;

          (b) by  either  the  Company  or  Acquiror  if the  other  shall  have
breached,  or failed to comply with, any of its obligations under this Agreement
or any  representation  or  warranty  made by such other  party  shall have been
incorrect  when made or shall  have since  ceased to be true and  correct in any
material respect,  and such breach,  failure or  misrepresentation  is not cured
within  thirty  (30) days  after  notice  thereof  and such  breach,  failure or
misrepresentation,  results  or would  reasonably  be  expected  to  result in a
Company Material Adverse Effect or an Acquiror Material Adverse Effect;

          (c) by  either  Acquiror  or the  Company  if  any  decree,  permanent
injunction,   judgment,  order  or  other  action  by  any  court  of  competent
jurisdiction or any Governmental  Entity preventing or prohibiting  consummation
of the Merger shall have become final and nonappealable;

          (d) by either  Acquiror or the Company if the Agreement  shall fail to
receive the requisite vote for approval and adoption by the  stockholders of the
Company at the Stockholders' Meeting;

          (e) by either the  Company or  Acquiror  if the merger  shall not have
been  consummated  before  June 30,  1998 (the  "Termination  Date");  provided,
however,  that the right to terminate this  Agreement  under this Section 9.1(e)
shall not be  available  to any party whose  failure to fulfill  any  obligation
under this  Agreement  has been the cause of, or resulted in, the failure of the
Effective Time to occur on or before the Termination Date.

          (f) by  Acquiror  if the  Board of  Directors  of the  Company  or any
committee   thereof   shall  have   withdrawn   or  modified   its  approval  or
recommendation  of the  Merger  or  this  Agreement  in any  manner  adverse  to
Acquiror,  or approved or recommended any  Acquisition  Proposal (other than the
Merger),  or shall have resolved to take any of the foregoing  actions (provided
that a  termination  pursuant to this  provision  will be subject to Section 9.3
hereof); and



                                       60

          (g) by the  Company if the Board of  Directors  of the  Company or any
committee   thereof   shall  have   withdrawn   or  modified   its  approval  or
recommendation  of the  Merger  or  this  Agreement  in any  manner  adverse  to
Acquiror,  or approved or recommended any  Acquisition  Proposal (other than the
Merger); provided, however, that the Company has complied with all provisions of
Section 7.10(b),  including the notice provisions therein,  and the requirements
of Section 9.3 hereof  (provided that the  termination  described in this clause

Acquiror the fee described in Section 9.3 hereof).

     SECTION 9.2.     EFFECT OF TERMINATION.

forthwith  become  void,  there shall be no  liability  on the part of Acquiror,
Merger Sub or the Company or any of their  respective  officers or  directors to
the other  parties  hereto and all rights and  obligations  of any party  hereto
shall  cease,  except (i) to the extent that such  termination  results from the
willful or reckless breach by any party hereto of any of its  representations or
warranties, or of any of its covenants or agreements, in each case, as set forth
in this  Agreement,  (ii) that nothing  herein  shall  relieve any party for any
breach of this Agreement and (iii) that Sections 7.2  (Confidentiality)  and 9.3
(Expenses) shall survive termination of this Agreement indefinitely.

     SECTION 9.3.     EXPENSES.

by wire transfer the amount of Twenty Million Dollars ($20,000,000) if:

          (i) the Company  terminates this Agreement pursuant to Section 9.1(g),
in which case, the Company Termination Fee must be paid simultaneously with such
termination;

          (ii) Acquiror terminates this Agreement pursuant to Section 9.1(f), in
which  case,  the  Company  Termination  Fee  must be paid no later  than  three
business days after the termination of this Agreement; or

          (iii) (A) Acquiror or the Company  terminates this Agreement  pursuant
to Section 9.1(d), (B) the approval of this Agreement by the stockholders of the

between the Company and any other person (other than Acquiror,  Merger Sub or an
affiliate of  Acquiror) or (2) the sale of 30% or



                                       61
<PAGE>

more (in voting power) of the voting securities of the Company or of 30% or more

     SECTION 9.4.     AMENDMENT.

          This Agreement may be amended by the parties hereto by action taken by
or on behalf of their  respective  Boards of  Directors at any time prior to the
Effective Time;  provided,  however,  that, after approval of this Agreement and
the Merger by the  stockholders  of the Company,  no amendment may be made which
would  reduce  the amount or change  the type of  consideration  into which each
share of Capital  Stock  shall be  converted  pursuant  to this  Agreement  upon
consummation  of the  Merger  or which by law  otherwise  requires  the  further
approval of such  stockholders.  This  Agreement may not be amended except by an
instrument in writing signed by the parties hereto.

     SECTION 9.5.     WAIVER.

          At any time prior to the Effective Time, each party may (a) extend the
time for the  performance  of any of the  obligations or other acts of the other

with any of the agreements or conditions  contained in this Agreement.  Any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such  party.  No delay or  failure  on the part of any party
hereto in exercising any right, power or privilege under this Agreement or under
any other  instrument or document  given in connection  with or pursuant to this
Agreement  shall impair any such right,  power or privilege or be construed as a
waiver of any default or any acquiescence therein. No single or partial exercise
of any such right,  power or privilege  shall  preclude the further  exercise of
such right,  power or  privilege,  or the exercise of any other right,  power or
privilege.

                        _________________ ________, 1997

Loral Space & Communications Ltd.
600 Third Avenue
New York, New York  10016

Ladies and Gentlemen:

          I have been  advised  that as of the date hereof I may be deemed to be
an  "affiliate"  of Orion Network  Systems,  Inc., a Delaware  corporation  (the
"Company"),  as the term  "affiliate"  is defined for purposes of paragraphs (c)
and (d) of Rule 145 of the rules and regulations  (the "Rules and  Regulations")
of  the  Securities  and  Exchange   Commission  (the  "Commission")  under  the
Securities Act of 1933, as amended (the "Act"). I have been further advised that
pursuant to the terms of the Agreement and Plan of Merger dated as of October 7,
1997 (the "Merger Agreement"),  among the Company,  Loral Space & Communications
Ltd.,  a Bermuda  company  ("Acquiror"),  and  Loral  Satellite  Corporation,  a
Delaware  corporation and  wholly-owned  subsidiary of Acquiror  ("Merger Sub"),
Merger Sub will be merged with and into the Company (the "Merger"),  and that as
a result of the Merger,  I may receive Acquiror Shares (as defined in the Merger
Agreement),  in  exchange  for shares of Common  Stock (as defined in the Merger
Agreement), owned by me.

          I  represent,  warrant and  covenant  to Acquiror  that in the event I
receive any Acquiror Shares as a result of the Merger:

          (a) I shall not make any sale,  transfer or other  disposition  of the
Acquiror Common Stock in violation of the Act or the Rules and Regulations.

          (b) I have  carefully  read this letter and the Merger  Agreement  and
discussed their respective requirements and other applicable limitations upon my
ability to sell, transfer or otherwise dispose of Acquiror Shares.

          (c) I have been  advised  that the  issuance of Acquiror  Shares to me
pursuant to the Merger will be registered with the Commission under the Act on a
Registration  Statement on Form S-4.  However,  I have also been  advised  that,
since at the time the Merger will be submitted for a vote of the stockholders of
the



                                       A-1
<PAGE>


Company,  I may be deemed  to have  been an  affiliate  of the  Company  and the
distribution by me of Acquiror  Shares has not been registered  under the Act, I
may not sell,  transfer or otherwise  dispose of Acquiror Shares issued to me in
the  Merger  unless  (i)  such  sale,  transfer  or other  disposition  has been
registered under the Act, (ii) such sale,  transfer or other disposition is made
in conformity  with the volume and other  limitations of Rule 145 promulgated by
the  Commission  under the Act, or (iii) in  accordance  with a legal opinion of
counsel  reasonably  acceptable  to  Acquiror,  such  sale,  transfer  or  other
disposition is otherwise exempt from registration under the Act.

          (d) I understand  that Acquiror is under no obligation to register the
sale,  transfer or other  disposition  of Acquiror  Shares by me or on my behalf
under the Act or to take any other action  necessary in order to make compliance
with an exemption from such registration available.

          (e) I also understand that stop transfer instructions will be given to
Acquiror's transfer agent with respect to Acquiror Shares and that there will be
placed  on  the   certificates   for  Acquiror  Shares  issued  to  me,  or  any
substitutions therefor, a legend stating in substance:

          "The securities  represented by this certificate have been issued in a
transfer to which Rule 145 promulgated  under the Securities Act of 1933 applies
and  may  only  be  sold  or  otherwise   transferred  in  compliance  with  the
requirements of Rule 145 or pursuant to a registration  statement under said act
or an exemption from such registration."

          (f) I also  understand  that unless the  transfer by me of my Acquiror
Shares has been  registered  under the Act or is a sale made in conformity  with
the  provisions  of Rule 145,  Acquiror  reserves the right to put the following
legend on the certificates issued to my transferee:

"The shares  represented by this  certificate have not been registered under the
Securities  Act of 1933 and were acquired from a person who received such shares
in a transaction to which Rule 145 promulgated  under the Securities Act of 1933
applies.  The shares have been acquired by the holder not with a view to, or for
resale in connection  with, any  distribution  thereof within the meaning of the
Securities  Act of 1933 and may not be sold,  pedged  or  otherwise



                                       A-2
<PAGE>

transferred  except  in  accordance  with an  exemption  from  the  registration
requirements of the Securities Act of 1933."

          It is  understood  and agreed that the legends set forth in paragraphs
(e) and (f) above  shall be  removed  by  delivery  of  substitute  certificates
without such legend if the  undersigned  shall have delivered to Acquiror a copy
of a letter from the staff of the  Commission,  or a legal opinion of counsel in
form and substance reasonably  satisfactory to Acquiror, to the effect that such
legend is not required for purposes of the Act.

          Execution of this letter should not be construed as an admission by me
that I am an  "affiliate"  of the Company as  described  in the first  paragraph
hereof or  considered as a waiver of any rights that I may have to object to any
claim that I am such an affiliate on or after the date hereof.

          I understand that pursuant to the Merger Agreement, no certificate for
Acquiror  Shares  shall  be  delivered  to  me  in  exchange  for   certificates
representing Common Stock until I have executed and delivered this Agreement.

                                       Very truly yours,

circumstances  except  Section 9.1(a) (with approval of the Company) and Section
9.1(c) of the Merger Agreement, (ii) all conditions set forth in Section 8.2 and
Section 8.3 (other than Section 8.2(c) and Section 8.3(c),  but it is understood
and  agreed  that  receipt of an  initial  FCC order  shall be deemed to satisfy
Section  8.2(c) and Section  8.3(c) for this  purpose)  of the Merger  Agreement
shall be deemed waived by each of Acquiror, Sub, and the Company,  respectively,
(iii)  Acquiror  and Sub  shall  each  use  their

                                       2

<PAGE>

reasonable  best  efforts to  consummate  the Merger (or the  Exchange  Offer as
applicable) as promptly as  practicable,  except to the extent that (and so long
as)  consummation  of the Merger (or the  Exchange  Offer as  applicable)  would
violate  applicable  law  (and  if  consummation  of the  Merger  would  violate
applicable  law, but conducting the Exchange Offer would not violate  applicable
law,  Acquiror shall conduct the Exchange Offer pursuant to the  requirements of
Section 7.15 (including  Section 7.15(g)),  except as otherwise provided in this
paragraph rather than the Merger).

     (c) If  following  the  exercise  of the  Option  there  is an  Acquisition
Proposal  pending prior to consummation of the Merger or the Exchange Offer, and
such Acquisition  Proposal  includes a per Share price higher than the per Share
consideration  to be paid in the Merger or the Exchange  Offer as  applicable (a
"Topping  Bid"),  Acquiror  shall have the right to tender the Shares  purchased
under the Option into the Topping Bid or  otherwise  support the Topping Bid and
realize value therefrom,  and Acquiror's  obligations under the Merger Agreement
(and  Section 1.6 hereof)  shall (if not  previously  terminated)  be  suspended
during the pendency of the Topping Bid; provided, however, that such obligations
shall cease to be  suspended  if the Topping Bid ceases to be pending  without a
majority of the Shares having been acquired pursuant to the Topping Bid.

     SECTION 1.3. CLOSING DATE.

     In the event  Acquiror  wishes to exercise  the  Option,  which may only be
exercised  in whole (but not in part),  with respect to all of the Shares of all
of the  Stockholders  covered hereby it shall send to each Stockholder a written
notice  (the  date of which  being  herein  referred  to as the  "Notice  Date")
specifying a place and date not earlier than five  business  days nor later than
20  Business  Days from the Notice Date for the  closing of such  purchase  (the
"Closing Date");  provided that if the closing of the purchase and sale pursuant
to the Option (the "Closing")  cannot be consummated by reason of any applicable
judgment, decree, order, law or regulation,  Acquiror shall use its commercially
reasonable efforts to resolve such matters and close as promptly as practicable.
Without  limiting the  foregoing,  if prior  notification  to or approval of any
regulatory authority is required in connection with such purchase, Acquiror and,
if  applicable,  a  Stockholder  shall  promptly  file the  required  notice  or
application  for  approval  and shall  expeditiously  process the same (and such
Stockholder  shall  cooperate  with Acquiror in the filing of any such notice or
application and the obtaining of any such approval).

     SECTION 1.4. PAYMENT AND DELIVERY OF CERTIFICATES.

     (a) Subject to the terms and conditions of this  Agreement,  in reliance on
the  representations,  warranties  and covenants of each  Stockholder  contained
herein  and in full  payment  for the  Shares,  at the  Closing,  Acquiror  will
deliver,   or  cause  to  be  delivered,   to  each  Stockholder,   certificates
representing the



                                       3
<PAGE>

Acquiror  Shares  to be  paid  pursuant  to  Section  1.1  duly  issued  to each
Stockholder, together with any necessary stock transfer stamps properly affixed.
Subject  to the terms and  conditions  in this  Agreement,  in  reliance  on the
representations,  warranties and covenants of the Acquiror  contained herein and
in the Merger  Agreement,  at the Closing,  the  Stockholders  shall  deliver to
Acquiror  certificates  representing  the  Shares  sold by the  Stockholders  to
Acquiror at the Closing,  duly endorsed in blank or  accompanied by stock powers
duly executed by the Stockholders in blank, in proper form for transfer.

     (b) No certificates or scrip  representing  less than one share of Acquiror
Shares  shall be issued upon the  exercise  of the  Option.  In lieu of any such
fractional  share,  each Stockholder who would otherwise have been entitled to a
fraction of a share of Acquiror Shares upon exercise of the Option shall be paid
at the Closing cash (without  interest) in an amount equal to such Stockholder's
fractional  part of a share of Acquiror  Shares  multiplied by the last reported
sale price of Acquiror Shares, as reported on the NYSE, on the Closing Date.

     SECTION 1.5. LEGENDS.

     (a) Each  Stockholder  shall instruct the Company to cause each certificate
of any Stockholder evidencing the Shares to bear a legend in the following form:

     THE SHARES  REPRESENTED BY THIS  CERTIFICATE MAY NOT BE SOLD,  EXCHANGED OR
     OTHERWISE  TRANSFERRED  OR DISPOSED OF EXCEPT IN COMPLIANCE  WITH THE TERMS
     AND CONDITIONS OF THE PRINCIPAL  STOCKHOLDER  AGREEMENT DATED AS OF OCTOBER
     7, 1997 AS IT MAY BE  AMENDED,  AMONG LORAL  SPACE &  COMMUNICATIONS  LTD.,
     LORAL SATELLITE CORPORATION, ORION NETWORK SYSTEMS, INC. ("ISSUER") AND THE
     REGISTERED  HOLDER OF THIS  CERTIFICATE,  A COPY OF WHICH IS ON FILE AT THE
     PRINCIPAL EXECUTIVE OFFICES OF THE ISSUER.


     (b) In  the  event  that  the  Shares  shall  cease  to be  subject  to the
restrictions  on transfer set forth in this Agreement,  the Company shall,  upon
the  written  request  of  the  holder  thereof,  issue  to  such  holder  a new
certificate  evidencing  such  Shares  without  the legend  required  by Section
1.5(a).

     SECTION 1.6. VOTING AGREEMENT; AGREEMENT TO TENDER.

     (a) Each  Stockholder and Acquiror hereby  severally and not jointly agrees

the Company, however called, and in any action by consent of the stockholders of

obligation or agreement of the Company under the Merger Agreement or which would
result in any of the conditions to the Merger  Agreement not being fulfilled and
(iii)  against the following  actions  (other than pursuant to the terms of this
Agreement or the Merger Agreement): (A) any extraordinary corporate transaction,

shall not enter into any agreement or understanding the effect of which would be

Affiliates  will not or cannot  satisfy  the  conditions  precedent  thereto) to

     (c) If there is an Exchange  Offer  pursuant to Section  7.15 of the Merger
Agreement,  each Stockholder agrees to tender such Stockholder's Shares into the

Proposal (as defined in the Merger Agreement);

     (c) the  Company or any of its  Subsidiaries  shall have  entered  into any

announced its intention to take any of the  foregoing  actions,  with respect to
the  sale of 20% or more (in  voting  power)  of the  voting  securities  of the

defined in Section 13(d) of the Exchange Act), other than Acquiror or any of its
affiliates,  of beneficial ownership of (as defined in the Rule 13d-3 under t to
acquire  beneficial  ownership of,  securities  representing  35% or more of the
voting power of the Company;

provided  that no event set forth in this  Section  1.9 shall be deemed to occur
solely by reason of any agreement,  or any action that is taken, or of any event
that occurs, for which Acquiror has given its prior written consent.  As used in
this Agreement, "person" shall have the meaning specified in Section 13(d)(3) of
the Exchange Act.

     SECTION 1.10. CONVERTIBLE DEBENTURES.

     Each Stockholder  that holds Debentures  agrees that all Debentures held by

Debentures) in accordance with Section 15.1 of the Debenture Purchase Agreement,

but unissued Shares,  which upon issuance will be validly issued, fully paid and


                                       8
<PAGE>

nonassessable  Shares, and which will not be "control shares" within the meaning
of such Article ELEVENTH.

     Each Stockholder, severally and not jointly, hereby represents and warrants
to Acquiror as follows:


     SECTION 2.1. DUE ORGANIZATION, AUTHORIZATION, ETC.

of the jurisdiction of its  incorporation or organization.  Such Stockholder has
all  requisite  power  (corporate  or  otherwise)  to execute and  deliver  this

consummation of the transactions  contemplated  hereby have been duly authorized
by  all  necessary  action   (corporate  or  otherwise)  on  the  part  of  such
Stockholder. This Agreement has been duly executed and delivered by or on behalf
of such Stockholder and, assuming its due authorization,  execution and delivery
by  Acquiror,  constitutes  a  legal,  valid  and  binding  obligation  of  such
Stockholder, enforceable against such Stockholder in accordance with its terms.

     SECTION 2.2 NO CONFLICTS, REQUIRED FILINGS AND CONSENTS.

     (a) The execution and delivery of this Agreement by such  Stockholder  does
not, and the  performance  of this Agreement by such  Stockholder  will not, (i)
conflict with or violate the  Certificate of  Incorporation  by By-Laws or other
similar  organizational  documents  of  such  Stockholder  (in  the  case  of  a
Stockholder  that is a corporation,  partnership  or other legal  entity),  (ii)
conflict with or violate any statute, law, ordinance,  rule, regulation,  order,
decree or judgment  applicable to such  Stockholder or by which it or any of its

a default (with or without  notice or lapse of time, or both) under,  or give to
others any rights of termination, amendment, acceleration or cancellation of, or
result in the creation of a lien or encumbrance on any of the property or assets
of such  Stockholder or (if such  Stockholder  is a corporation,  partnership or
other legal entity) any of its subsidiaries,  including, without limitation, the
Shares,  pursuant to, any  indenture or other loan  document  provision or other
contract,  license, franchise, permit or other instrument or obligation to which
such  Stockholder  is a  party  or by  which  such  Stockholder  or  any  of its
properties is bound or affected,  except, in the case of clauses (ii) and (iii),
for any such breaches,  defaults or other occurrences that would



                                       9
<PAGE>

not prevent the performance by such  Stockholder of its  obligations  under this
Agreement.

     (b) The execution  and delivery of this  Agreement by such  Stockholder  do
not, and the performance of this agreement by such Stockholder will not, require
any  consent,   approval,   authorization  or  permit  of,  or  filing  with  or
notification to, any governmental or regulatory authority,  domestic or foreign,
except where the failure to obtain such consents,  approvals,  authorizations or
permits,  or to make  such  filings  or  notifications,  would not  prevent  the
performance by the Stockholder of its obligations under this Agreement.

     SECTION 2.3. TITLE TO SHARES.

     Such  Stockholder  has, and the transfer by the  Stockholder  of the Shares
hereunder will pass, good and marketable title to the Shares listed on Exhibit A
hereto, free and clear of any pledge, lien, security interest, mortgage, charge,
claim,  equity,  option,  proxy,  voting  restriction,  right of first  refusal,
limitation on  disposition,  adverse claim of ownership or use or encumbrance of
any kind  ("Encumbrances"),  except to the extent disclosed on Exhibit B and for
Shares sold prior to the Closing as permitted under Section 1.8.

     SECTION 2.4. NO BROKERS.

     Except as  contemplated  in the  Merger  Agreement,  no  broker,  finder or
investment  banker  is  entitled  to any  brokerage,  finder's  or other  fee or
commission in connection with the transactions contemplated by this Agreement.

     SECTION 2.5. INVESTMENT INTENT, ETC.

     Each  Stockholder  is acquiring  the  Acquiror  Shares,  together  with the
associated  rights,  to be received in the Merger or pursuant to the exercise of
the Option,  for its own account for  investment and not with a view towards the
resale,  transfer or  distribution  thereof,  nor with any present  intention of
distributing the Acquiror Shares.  Each Stockholder is an "accredited  investor"
within the meaning of Regulation D promulgated  under the Act. Each  Stockholder
has such knowledge and  experience in financial and business  matters that it is
capable of  evaluating  the merits and risks of an investment in Acquiror and is
able to bear the economic risk of such  investment  for an indefinite  period of
time.

                   REPRESENTATIONS AND WARRANTIES OF ACQUIROR

     SECTION 3.1. AUTHORITY RELATIVE TO THE AGREEMENT.

     (a) Acquiror has the corporate  power to execute and deliver this Agreement
and to carry out its obligations  hereunder.  The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby have been
duly authorized by Acquiror's  Board of Directors.  The Agreement  constitutes a
valid and  binding  obligation  of  Acquiror,  enforceable  against  Acquiror in
accordance  with its terms,  except as enforcement may be limited by bankruptcy,
insolvency or other similar laws affecting the enforcement of creditors'  rights
generally  and except that the  availability  of equitable  remedies,  including
specific performance, is subject to the discretion of the court before which any
proceeding therefor may be brought.  No other corporate  proceedings on the part
of Acquiror are necessary to authorize the execution and delivery by Acquiror of
this Agreement or the consummation of the transactions contemplated hereby.

     (b) The execution and delivery of this  Agreement and the  consummation  of
the transactions contemplated hereby, does not and will not result in the change
in  conversion  ratios,  conversion  rights or  voting  rights,  or the  breach,
violation,  default  (with  or  without  notice  or lapse  of  time,  or  both),
termination,  cancellation or  acceleration of any obligation,  or the loss of a
material benefit, under (i) the Acquiror's Memorandum of Association or bye-laws
or (ii) any  indenture  or other  loan  document  provision  or other  contract,
license,  franchise,  permit,  order,  decree,  concession,  lease,  instrument,
judgment,  statute, law, ordinance, rule or regulation applicable to Acquiror or
any of its Subsidiaries or their respective properties or assets, other than, in
the  case  of  clause  (ii)  only,  (A)  any  breaches,  violations,   defaults,
terminations, cancellations,  accelerations or losses which, either singly or in
the aggregate,  will not have a Acquiror  Material Adverse Effect or prevent the
consummation of the transactions contemplated hereby.

     SECTION 3.2. REPRESENTATIONS IN MERGER AGREEMENT.

     Acquiror   represents   and   warrants   to  each   Stockholder   that  the
representations  and warranties  set forth in Article V of the Merger  Agreement
were (or will be) true and  correct  when  made and on and as of the date of any
action taken by Acquiror hereunder (including without limitation exercise of the
Option) with the same effect as though such  representations  and warranties had
been made on and as of such date (except for representations and warranties that
speak as of a specific  date or time,  which need only be true and correct as of
such date or  time),  except  where  the  failure  of such  representations  and
warranties to be so true and correct (without giving effect to any limitation as
to "materiality"  or "Acquiror  Material Adverse Effect" set forth therein) does
not have an Acquiror  Material  Adverse  Effect,  and such  representations  and
warranties  shall  be  deemed



                                       11
<PAGE>


incorporated herein;  provided,  however, that incorporated  representations and
warranties  which relate to the Merger Agreement shall be deemed for purposes of
this Section to have been modified to relate only to this Agreement.

                                   ARTICLE IV.

                         DISTRIBUTIONS; ADJUSTMENT UPON
                           CHANGES IN CAPITALIZATION.

     (a) Any dividends or other distributions (whether payable in cash, stock or
otherwise) by the Company with respect to any Shares purchased  hereunder with a
record date on or after the Closing  Date will belong to  Acquiror.  If any such
dividend  or  distribution  belonging  to Acquiror is paid by the Company to the
Stockholder,  the Stockholder  shall hold such dividend or distribution in trust
for  the  benefit  of  Acquiror  and  shall  promptly  remit  such  dividend  or
distribution   to  Acquiror  in  exactly  the  form  received,   accompanied  by
appropriate  instruments of transfer.  If on or after the date of this Agreement
there shall occur any stock dividend, stock split, recapitalization, combination

receive for the aggregate price payable upon exercise of the Option with respect
to the  Shares,  all such  shares  of  stock,  other  securities,  cash or other
property  issued,  delivered or received  with respect to such Shares (or if the
Option shall not be exercised, appropriate adjustment shall be made for purposes
of the calculations set forth in this Agreement).

     Any dividends or other  distributions  (whether  payable in cash,  stock or
otherwise) by Acquiror with respect to any Acquiror Shares issued hereunder with

which  such  Acquiror  Shares  were  issued.  If on or  after  the  date of this
Agreement there shall occur any stock dividend,  stock split,  recapitalization,

for the aggregate price payable to such Stockholder upon exercise of the Option,
all such  shares of stock,  other  securities,  cash or other  property  issued,
delivered or received  with  respect to the  Acquiror  Shares to be delivered to
such  Stockholder  (or  if  the  Option  shall  not  be  exercised,  appropriate

                        NO SOLICITATION OF TRANSACTIONS.

     Each Stockholder severally and not jointly covenants and agrees that in its
capacity  as a  stockholder  of the Company it shall not,  through any  officer,
director, employee,  representative,  agent or direct or indirect stockholder of
the Company or any Company Subsidiary,  directly or indirectly,  take any action
to (i)  encourage,  initiate  or solicit the  submission  of any  proposal  that
constitutes an Acquisition Proposal,  (ii) enter into any agreement with respect
to or accept any Acquisition  Proposal or (iii)  facilitate any inquiries or the
making of any proposal that  constitutes,  or may reasonably be expected to lead
to, an Acquisition  Proposal.  The Stockholder shall promptly notify Acquiror in
writing of any request  for  information  or  Acquisition  Proposal,  specifying
reasonable  details  of any  inquiry  or  Acquisition  Proposal,  and shall keep
Acquiror informed as to the status of any such discussions or negotiations. Each
Stockholder  severally and not jointly further agrees to use its best efforts as
a  stockholder  to cause the Company not to,  directly or  indirectly,  solicit,
initiate,  seek, or encourage  (including by way of  furnishing  information  or
assistance),  or take other action to facilitate, any inquiries or the making of
any proposal  which  constitutes  or may  reasonably  be expected to lead to, an
Acquisition Proposal.

                                   ARTICLE VI.

                         COVENANTS OF THE STOCKHOLDERS.

     SECTION 6.1. NEGATIVE COVENANTS.

     Each Stockholder agrees, until the Option has terminated, not to:

     (a) sell, transfer,  pledge,  assign or otherwise dispose of, or enter into
any contract,  option or other  arrangement with respect to the sale,  transfer,
pledge, assignment or other disposition of, the Shares owned by such Stockholder
to any  person  other  than  Acquiror  or  Acquiror's  designee  and  except  as
contemplated in Exhibit B;

     (b) acquire any additional shares of Common Stock without the prior consent
of Acquiror  other than  pursuant to rights  under the  Company  Stock  Purchase
Plans,  options  outstanding on the date of this Agreement,  or Shares issued in
payment of interest on the Debentures or dividends on the Series C Shares;

     (c) deposit any Shares into a voting trust or grant a proxy or enter into a
voting agreement with respect to any Shares, except for this Agreement; or


                                       13
<PAGE>

     (d) take any action that would make any  representation or warranty of such
Stockholder  contained herein untrue or incorrect or would result in a breach by
such  Stockholder  of its  obligations  under this  Agreement or a breach by the
Company of its obligations under the Merger Agreement.

     SECTION 6.2. RELIANCE; FURTHER ASSURANCES.

     Each  Stockholder  understands and  acknowledges  that Acquiror and Sub are
entering into the Merger Agreement in reliance upon each Stockholder's execution
and  delivery  of this  Agreement.  If  Acquiror  shall  exercise  the Option in
accordance  with the  terms of this  Agreement,  from  time to time and  without
additional  consideration the Stockholder will execute and deliver,  or cause to
be executed and delivered,  such additional or further  transfers,  assignments,
endorsements,  consents and other instruments as Acquiror may reasonably request
for the purpose of effectively  carrying out the  transactions  contemplated  by
this Agreement, includi any and all Encumbrances with respect thereto.

     SECTION 6.3. TRANSFER OF ACQUIROR SHARES BY BRITISH AEROSPACE.

British  Aerospace Space Systems, Inc. and British Aerospace Holdings,
Inc.  (collectively,  "BAe") and Acquiror  agree to consult and  cooperate  with
respect to the orderly  disposition  of  Acquiror  Shares  obtained by BAe.  BAe
agrees that for a period of twelve months from the date it acquires the Acquiror
Shares  it will not,  and will  cause  each of its  affiliates  not to,  sell or
otherwise  transfer any Acquiror Shares other than by means of a block trade (or
a series  of block  trades)  with an  entity  that  qualifies  as a block  trade
positioner  (as that  term is  defined  and/or  interpreted  under  the  federal
securities  laws and the rules and  regulations  promulgated  thereunder) who is
experienced in block trade  transactions.  BAe shall consult with Acquiror prior
to such sale and seek the consent of Acquiror to such sale,  which consent shall
not be  unreasonably  withheld,  conditioned  or  delayed.  In the event of such
withholding  of consent,  BAe shall have the right to revise the proposed  sale,
and Acquiror shall  reconsider the revised sale in accordance  with the standard
of this Section. No delay in any proposed sale shall be beyond the expiration of
the twelve-month period. As an alternative to conducting block trades, BAe shall
have the  right to sell all (but  not  less  than  all) of its  Acquiror  Shares
pursuant to an underwritten  sale with an underwriter  reasonably  acceptable to
Acquiror. In such event, Acquiror shall modify the registration  statement filed
pursuant to Section 6.5 (or file a separate  registration  statement meeting the
requirements  of  Section  6.5) to enable  BAe to effect  such  sale.  Except as
provided in the prior  sentence,  Acquiror  shall not be  obligated to conduct a
"road show" or otherwise  support such sale.

     SECTION 6.4. AFFILIATE AGREEMENT.

     Each  Stockholder  acknowledges  that  such  Stockholder  may be  deemed an
affiliate (as defined in Rule 12b-2 of the rules  promulgated under the Exchange
Act) of the  Company,  Acquiror or Sub, and further  acknowledges  and agrees to
transfer,  sell or  otherwise  dispose of Acquiror  Shares  (including  Acquiror
Shares  acquired  upon the  exercise  of  options,  warrants  or  rights  or the
conversion or exchange of convertible or  exchangeable  securities)  only (a) if
such  transfer,  sale or  disposition  is  registered  under the Act,  (b) is in
compliance  with  the  requirements  of  paragraphs  (c)  and  (d) of  Rule  145
promulgated  under the Act ("Rule 145") (as indicated in the restrictive  legend
that will appear on the stock certificate), or (c) pursuant to another exemption
from registration under the Act for such offer and sale. Each Stockholder agrees
not to make an illegal  "distribution"  (within  the meaning of the Act and Rule
145) of Acquiror Shares. Acquiror shall be entitled to place restrictive legends
upon  certificates  for  each  Stockholder's  Acquiror  Shares  to  enforce  the
applicable  provisions  of law and this  Agreement  and  Acquiror  shall  not be
required to maintain the effectiveness of the Proxy  Registration  Statement (or
Exchange  Registration  Statement,  as the  case may be)  under  the Act for the
purposes of resale of Acquiror Shares by each Stockholder.

     SECTION 6.5. REGISTRATION RIGHTS.

     (a) In the event  that  Acquiror  exercises  the  Option,  as  promptly  as
practicable  following  the closing date for the exchange  offer  referred to in
Section  1.2  above  (but not more than 60 days  following  the  Closing  Date),
Acquiror  shall (i) file a shelf  registration  statement  covering all Acquiror
Shares for the  purposes of resale of Acquiror  Shares by each  Stockholder  and
(ii) use its reasonable best efforts to cause such shelf registration  statement
to become and remain  effective  for the resale of all  Acquiror  Shares  issued
pursuant to this Agreement;  provided,  however, that Acquiror shall be required
to include in such registration statement only those Acquiror Shares as to which
the  Stockholder  holding  such  Acquiror  Shares  agrees to sell such shares in
compliance  with the  requirements  of  paragraphs  (c) and (d) of Rule 145 that
would  have  been  applicable  to such  sale if such  Acquiror  Shares  had been
registered  under the Proxy  Registration  Statement  (or Exchange  Registration
Statement, as the case may be) rather than such shelf registration statement.

     (b)  Registrations  effected  under  this  Section  shall  be  effected  at
Acquiror's  expense,  including  the fees and  expenses  of one  counsel  to the
holders of Acquiror Shares, but excluding underwriting discounts and commissions
to brokers or dealers.  In connection with each registration under this Section,
Acquiror  shall  indemnify and hold each holder of Acquiror  Shares whose shares
are registered  pursuant to such  registration  statement (a "Holder of Acquiror
Shares"),  its  underwriters and each of their  respective  affiliates  harmless
against  any  and  all  losses,  claims,   damages,   liabilities  and  expenses
(including,   without   limitation,



                                       15
<PAGE>


investigation  expenses and fees and  disbursements of counsel and accountants),
joint or several,  to which such Holder of Acquiror Shares, its underwriters and
each of their respective affiliates may become subject, under the Securities Act
or otherwise,  insofar as such losses, claims, damages,  liabilities or expenses
(or  actions  in  respect  thereof)  arise  out of or are  based  upon an untrue
statement  or alleged  untrue  statement  of a material  fact  contained in such
registration  statement (including any prospectus therein),  of any amendment or
supplement  thereto,  or arise out of or are based upon the  omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements therein not misleading, other than such losses,
claims,  damages,  liabilities or expenses (or actions in respect thereof) which
arise out of are based upon an untrue statement or alleged untrue statement of a
material fact contained in written information furnished by a Holder of Acquiror
Shares to Acquiror expressly for use in such registration  statement;  provided,
however,  that the  foregoing  indemnity  shall not inure to the  benefit of any
Holder of Acquiror Shares, its underwriters or respective affiliates,  if a copy
of the  prospectus  was not sent or given by or on behalf of such  person to the
person purchasing the Shares,  if required by law so to have been delivered,  at
or prior to the written  confirmation  of the sale of the Shares to such person,
and if the  prospectus  (as so  amended  or  supplemented)  would have cured the
defect giving rise to such loss, claim, damage or liability.

     (c) In connection with any registration statement pursuant to this Section,
each Holder of Acquiror Shares agrees to furnish  Acquiror with such information
concerning  itself and the proposed sale or distribution as shall  reasonably be
required in order to ensure  compliance with the  requirements of the Securities
Act.  Each Holder of Acquiror  Shares shall  indemnify  and hold  Acquiror,  its
underwriters  and each of their respective  affiliates  harmless against any and
all  losses,  claims,  damages,  liabilities  and  expenses  (including  without
limitation  investigation  expenses  and fees and  disbursements  of counsel and
accountants),  joint or several, to which Acquiror, its underwriters and each of
their  respective  affiliates  may become  subject under the  Securities  Act or
otherwise,  insofar as such losses, claims, damages, liabilities or expenses (or
actions in respect  thereof) arise out of or are based upon an untrue  statement
or alleged untrue statement of a material fact contained in written  information
furnished by any Holder of Acquiror Shares to Acquiror expressly for use in such
registration  statement.  In no event  shall  the  liability  of any  Holder  of
Acquiror Shares or any affiliate thereof under this Section be greater in amount
than the dollar  amount of the  proceeds  received  by such  Holder of  Acquiror
Shares upon the sale of the Acquiror Shares giving rise to such  indemnification
obligation.

     (d) Upon the issuance of Acquiror Shares  hereunder,  Acquiror will use its
reasonable best efforts  promptly to list such Acquiror Shares with the New York
Stock Exchange or on such national or other  exchange on which  Acquiror  Shares
are at the time principally listed.

                              ORION NETWORK SYSTEMS
                             TO BE ACQUIRED BY LORAL


Rockville, Maryland -- Orion Network Systems, Inc. (NASDAQ:ONSI) announced today
that it has entered  into a definitive  merger  agreement in which Loral Space &
Communications  Ltd.  (NYSE:LOR) will acquire Orion in exchange for Loral common
stock. At the time the transaction closes, each outstanding share of Orion stock
will be converted  into $17.50 worth of Loral common stock,  subject to possible
adjustment  based on Loral's stock price, as explained  below.  Based on Orion's
fully diluted share base of approximately 28 million shares, the equity value of
the transaction is  approximately  $490 million.  As of June 30, 1997, Orion had
approximately $723 million of debt which is expected to remain outstanding after
the transaction and had cash on hand of approximately $480 million.

Gustave M. Hauser,  Chairman of the Orion Board of Directors stated:  "Orion has
been constructing and operating a modern,  high-capacity international satellite
communications  system  capable  of  providing  service  to 85%  of the  world's
population.   We  believe  that  with  Loral's   diversified  space  assets  and
significant  resources,  the combination will enhance Orion's ability to exploit
its global  business  opportunities  and permit Orion's  shareholders to realize
increased value."

W. Neil Bauer,  Orion's  President and CEO added:  "We are excited about the new
opportunities  Loral will bring to Orion and its employees.  Orion looks forward
to being part of Loral's  expanded  satellite  services  business  that includes
Skynet,  Globalstar  and  CyberStar.  We  think  Orion  will  contribute  a  key
networking  capability to enhance Loral's  ability to serve the  rapidly-growing
international Internet and corporate data markets."

Orion  owns and  operates  the Orion 1  satellite,  placed in service in January
1995,  serving  the  European,  transatlantic  and  U.S.  markets  and  has  two
additional  satellites  under  construction,  the cost of which was fully funded
through  the public  issuance of debt  earlier  this year.  Orion's  transponder
capacity will increase  substantially  with the launching of Orion 3,  scheduled
for service in January  1999,  covering  the Asia Pacific  region,  and Orion 2,
which will serve the Americas and Europe  beginning in June 1999. Orion serves a
customer base of 260 multinational  businesses and Internet service providers in
47 countries via approximately  630 installed  terminals (earth stations or very
small aperture  terminals [VSATs]) that

receive networked  value-added services from Orion 1. The Company also transmits
video communications for television and other program distribution services.

Orion  believes that the synergy  between  Loral's  current  satellite  services
portfolio  and Orion's  assets would allow Loral to provide  higher  value-added
satellite  services  and to extend  its  reach  into  high-growth  international
markets.  Orion believes that its strategy of continuing to expand globally with
high value-added networking solutions, including transoceanic Internet access to
service providers,  which yield  significantly  greater revenues per transponder
than traditional  satellite  transponder leasing businesses,  is consistent with
Loral's stated  strategy.  Orion's strong  technology base in this market should
add considerable  strength to Loral's broadband networking CyberStar project, as
well as other areas of Loral's business.

The  transaction  is expected to close in the first  quarter of 1998  subject to
Federal Communications Commission (FCC), Hart-Scott-Rodino and Orion stockholder
approval. Although not a condition of the transaction,  Orion intends to seek an
IRS ruling as to  eligibility  for a tax-free  exchange.  Loral is also entering
into agreements with  approximately  35 percent of the holders of Orion's stock,
the effect of which will be to require them to vote in favor of the  transaction
and will give Loral an option to buy those shares in certain circumstances.  The
boards of directors of both Loral and Orion have approved the transaction.

The exchange ratio mechanics are as follows:  If the price of Loral common stock
(over  a  specified  period)  is  trading  above  approximately   $24.46,  Orion
stockholders  will receive 0.71553 Loral shares and will receive value in excess
of $17.50. If the price is below approximately  $16.31,  Orion shareholders will
receive 1.07329 Loral shares and the value received will decrease.

Morgan  Stanley & Co.  Incorporated  acted as financial  advisor to Orion Nework
Systems in this transaction.

and Asia Pacific satellite under construction and related ground facilities.

Editor's Note:

operation  since January 1995 and serves Europe,  the United States to the Rocky
Mountains  and portions of Canada and Mexico.  Orion's  Asia Pacific  satellite,
located at 139o East Longitude, is scheduled for launch in October 1998 and will
serve the Pacific Rim region including,  Australia,  China, India, Japan, Korea,
Eastern Russia and Hawaii. A third  satellite,  scheduled for launch in mid-1999
and  located at 12o West  Longitude,  will  supplement  Orion's  existing  North
American and European  coverage and expand  Orion's  service  capabilities  into
Latin America,  Russia,  and the Middle East.  These two additional  satellites,
together  with Orion's  first  satellite,  will enable  Orion to provide  global
communications services to over 85% of the world's population.
