                              February 19, 1998 

Dear Stockholder: 

   You are cordially invited to attend a special meeting of stockholders (the 
"Special Meeting") of Orion Network Systems, Inc. ("Orion"), to be held on 
Friday, March 20, 1998 at 9:00 a.m., local time, at 2440 Research Boulevard, 
Suite 400, Rockville, Maryland. 

   As described in the accompanying Proxy Statement/Prospectus, at the 
Special Meeting, Orion stockholders will be asked to consider and vote upon 
the following proposals: 

   (1)  Approval and adoption of the Agreement and Plan of Merger, dated as 
of October 7, 1997, as amended on February 11, 1998 (the "Merger Agreement"), 
among Orion, Loral Space & Communications Ltd., a Bermuda company ("Loral"), 
and Loral Satellite Corporation, a newly formed Delaware corporation and a 
wholly owned subsidiary of Loral ("Merger Subsidiary") and the transactions 
contemplated thereunder, including the Merger (as defined therein). 

   (2)  Approval of amendments to Orion's Non-Employee Director Stock Option 
Plan (the "Director Option Plan") and certain options granted thereunder to 
provide for early vesting of certain options and conversion of options 
granted under the plan in connection with the Merger. 

   (3)  Approval of amendments to the Stock Option Agreement, dated as of 
July 17, 1996, by and between Orion and John G. Puente, a director and 
Chairman of the Executive Committee of Orion's Board of Directors (the 
"Puente Option Agreement"), and the options granted thereunder to provide for 
conversion of such options in connection with the Merger. 

   (4)  Approval of amendments to the Stock Option Agreement, dated as of 
March 12, 1997, by and between Orion and Gustave M. Hauser, a director and 
Chairman of Orion's Board of Directors (the "Hauser Option Agreement"), and 
the options granted thereunder to provide for conversion of such options in 
connection with the Merger. 

   (5)  To transact such other business as may properly come before the 
Special Meeting, or any adjournments or postponements thereof. 

   The accompanying Proxy Statement/Prospectus provides a detailed 
description of the Merger, including Orion's reasons for entering into the 
Merger Agreement and the effect of the Merger on Orion and its stockholders, 
and the amendments to the Director Option Plan and Puente and Hauser Option 
Agreements. I urge you to read the accompanying Proxy Statement/Prospectus 
(including the attachments thereto) and the accompanying Notice of Special 
Meeting carefully. 

   Your Board of Directors has carefully reviewed and considered the terms 
and conditions of the Merger Agreement and recommends that stockholders vote 
for approval and adoption of the Merger Agreement. In reaching this 
conclusion, the Board of Directors considered, among other things, the 
opinion dated October 6, 1997 of Morgan Stanley & Co. Incorporated ("Morgan 
Stanley") that, as of such date and based on and subject to the matters set 
forth therein, the exchange ratio set forth in the Merger Agreement is fair 
from a financial point of view to the holders of Orion Common Stock (other 
than Loral and its affiliates) and, assuming the conversion of the Orion 
Preferred Stock into Orion Common Stock in accordance with their terms, to 
the holders of Orion Preferred Stock. A copy of Morgan Stanley's opinion, 
including the assumptions, qualifications and other matters contained 
therein, is included in the Proxy Statement/Prospectus as Attachment C. Your 
Board of Directors also recommends that stockholders vote for approval of the 
amendments to the Director Option Plan and Puente and Hauser Option 
Agreements. 

   The matters to be considered and voted upon at the Special Meeting are of 
great importance to your investment and the future of Orion. Regardless of 
your plans for attending in person, it is important that 
<PAGE>
your shares be represented and voted at the Special Meeting. Accordingly, you 
are requested to complete, sign, date, and return the enclosed proxy card in 
the enclosed postage paid envelope. Signing this proxy will not prevent you 
from voting in person should you be able to attend the Special Meeting, but 
will assure that your vote is counted if, for any reason, you are unable to 
attend. 

   Please do not send your stock certificates with your proxy card. If the 
Merger Agreement is approved by the Orion stockholders and the Merger is 
consummated, you will receive a transmittal form and instructions for the 
surrender and exchange of your shares. 

   We hope that you can attend the Special Meeting. Your interest and support 
in the affairs of Orion Network Systems, Inc. are appreciated. 

                                          Sincerely, 



                                          W. Neil Bauer 
                                          President and Chief 
                                          Executive Officer

                  NOTICE OF SPECIAL MEETING OF STOCKHOLDERS 
                         TO BE HELD ON MARCH 20, 1998 

   NOTICE IS HEREBY GIVEN that a special meeting of stockholders (the 
"Special Meeting") of Orion Network Systems, Inc. ("Orion") will be held on 
Friday, March 20, 1998 at 9:00 a.m., local time, at 2440 Research Boulevard, 
Suite 400, Rockville, Maryland, to consider and act upon the following 
proposals: 

   1.     To approve and adopt the Agreement and Plan of Merger, dated as of 
          October 7, 1997, as amended on February 11, 1998 (the "Merger 
          Agreement"), among Orion, Loral Space & Communications Ltd., a 
          Bermuda company ("Loral"), and Loral Satellite Corporation, a newly 
          formed Delaware corporation and a wholly owned subsidiary of Loral 
          ("Merger Subsidiary"), and the transactions contemplated 
          thereunder, including the Merger (as defined therein). 

   2.     To approve amendments to Orion's Non-Employee Director Stock Option 
          Plan (the "Director Option Plan") and certain options granted 
          thereunder to provide for early vesting of certain options and 
          conversion of options granted under the plan in connection with the 
          Merger. 

   3.     To approve amendments to the Stock Option Agreement, dated as of 
          July 17, 1996, by and between Orion and John G. Puente, a director 
          and Chairman of the Executive Committee of Orion's Board of 
          Directors (the "Puente Option Agreement"), and the options granted 
          thereunder to provide for conversion of such options in connection 
          with the Merger. 

   4.     To approve amendments to the Stock Option Agreement, dated as of 
          March 12, 1997, by and between Orion and Gustave M. Hauser, a 
          director and Chairman of Orion's Board of Directors (the "Hauser 
          Option Agreement"), and the options granted thereunder to provide 
          for conversion of such options in connection with the Merger. 

   5.     To transact such other business as may properly come before the 
          Special Meeting, or any adjournments or postponements thereof. 

   The Board of Directors has carefully considered the terms of the Merger 
Agreement, and believes that the Merger is in the best interests of Orion and 
its stockholders. The Board of Directors also believes that amendments of the 
Director Option Plan and the Puente Option Agreement and Hauser Option 
Agreement are in the best interests of Orion and its stockholders. The Board 
of Directors has unanimously approved the matters being submitted by Orion 
for stockholder approval at the Special Meeting and recommends that 
stockholders vote FOR approval and adoption of the Merger Agreement and FOR 
approval of each of the amendments of the Director Option Plan and the Puente 
Option Agreement and Hauser Option Agreement. Certain members of the Orion 
Board of Directors and their affiliated companies holding, in the aggregate, 
approximately 32% of the voting stock outstanding as of February 12, 1998, 
have agreed to vote for approval and adoption of the Merger Agreement. In 
addition, Space Systems/Loral, Inc. ("SS/L"), a wholly-owned subsidiary of 
Loral, holds approximately 2.7% of the voting stock of Orion oustanding as of 
February 12, 1998, and will vote for approval and adoption of the Merger 
Agreement. 

   Approval of the Merger Agreement requires the affirmative vote of the 
holders of a majority of the shares of Orion common stock and Orion preferred 
stock, voting together as a single class. Orion stockholders have no 
dissenters' rights in connection with the matters submitted by Orion for 
stockholder approval at the Special Meeting. 

   Pursuant to Orion's Amended and Restated By-laws, the Board of Directors 
has fixed the close of business on February 5, 1998 as the record date for 
the determination of stockholders entitled to notice of and to vote at the 
Special Meeting. Only holders of Orion common stock and Orion preferred stock 
of record at the close of business on that date will be entitled to notice of 
and to vote at the Special Meeting or any adjournments or postponements 
thereof. A list of Orion's stockholders entitled to vote at the Special 
Meeting will be open to the examination of any stockholder for any purposes 
germane to the Special Meeting during ordinary business hours for a period of 
ten (10) days before the Special Meeting at Orion's offices. 

   Information regarding the proposed Merger, the Merger Agreement and 
related matters is contained in the accompanying Proxy Statement/Prospectus 
and the attachments thereto, which are incorporated by reference herein and 
form part of this Notice. 

                                                          By Order of the 
                                                          Board of Directors 

                                                          Richard H. Shay 
                                                          Secretary

                 LORAL SPACE & COMMUNICATIONS LTD. PROSPECTUS 

                       SPECIAL MEETING OF STOCKHOLDERS 
                        OF ORION NETWORK SYSTEMS, INC. 
                         TO BE HELD ON MARCH 20, 1998 

   This Proxy Statement/Prospectus ("Proxy Statement/Prospectus") is being 
furnished to stockholders of Orion Network Systems, Inc. ("Orion") in 
connection with the solicitation by the Board of Directors of Orion of 
proxies to be used at a special meeting of stockholders of Orion (the 
"Special Meeting") and at any adjournments or postponements thereof. The 
Special Meeting will be held on Friday, March 20, 1998 at 9:00 a.m., local 
time, at 2440 Research Boulevard, Suite 400, Rockville, Maryland. 

   This Proxy Statement/Prospectus also constitutes the prospectus of Loral 
(as defined below) for an estimated 27,442,163 shares of Loral Common Stock 
(as defined below) to be issued in connection with the Merger (as defined 
below) under the Securities Act of 1933 (the "Securities Act"). Each new 
share of Loral Common Stock (as defined below) issued in connection with the 
Merger (as defined below) will be accompanied by one Loral Right (as defined 
below). Loral has filed a Registration Statement on Form S-4 with the 
Securities and Exchange Commission (the "Commission") with respect to such 
shares, of which this Proxy Statement/Prospectus is a part. This Proxy 
Statement/Prospectus and form of proxy are first being sent or given to 
stockholders on or about February 19, 1998. 

   At the Special Meeting, Orion stockholders will be asked to consider and 
vote upon the following proposals: 

   (1) Approval and adoption of the Agreement and Plan of Merger, dated as of 
October 7, 1997, as amended on February 11, 1998 (the "Merger Agreement"), 
among Orion, Loral Space & Communications Ltd., a Bermuda company ("Loral"), 
and Loral Satellite Corporation, a newly formed Delaware corporation and a 
wholly owned subsidiary of Loral ("Merger Subsidiary") and the transactions 
contemplated thereunder, including the Merger (as defined below). 

   (2) Approval of amendments to Orion's Non-Employee Director Stock Option 
Plan (the "Director Option Plan") and certain options granted thereunder to 
provide for early vesting of certain options and conversion of options 
granted under the plan in connection with the Merger. 

   (3) Approval of amendments to the Stock Option Agreement, dated as of July 
17, 1996, by and between Orion and John G. Puente, a director and Chairman of 
the Executive Committee of Orion's Board of Directors (the "Puente Option 
Agreement"), and the options granted thereunder to provide for conversion of 
such options in connection with the Merger. 

   (4) Approval of amendments to the Stock Option Agreement, dated as of 
March 12, 1997, by and between Orion and Gustave M. Hauser, a director and 
Chairman of Orion's Board of Directors (the "Hauser Option Agreement"), and 
the options granted thereunder to provide for conversion of such options in 
connection with the Merger. 

   (5) To transact such other business as may properly come before the 
Special Meeting, or any adjournments or postponements thereof. 

   Merger. Pursuant to the Merger Agreement, Merger Subsidiary will be merged 
with and into Orion (the "Merger"). Orion will be the surviving corporation 
(the "Surviving Corporation") in the Merger and will become a wholly owned 
subsidiary of Loral. 

   In the Merger, persons who hold shares of (i) common stock, par value $.01 
per share, of Orion ("Orion Common Stock"), excluding treasury shares and 
shares owned by Loral or its subsidiaries, and (ii) preferred stock, par 
value $.01 per share, of Orion ("Orion Preferred Stock", and together with 
Orion Common Stock, "Orion Capital Stock"), excluding treasury shares and 
shares owned by Loral or its subsidiaries, will receive a pre-determined 
amount of common stock, par value $.01 per share, of Loral ("Loral Common 
Stock"). Shares of Orion Capital Stock owned by Loral or any subsidiary of 
Loral will be converted into the right to receive enough shares in the 
Surviving Corporation as necessary in order to ensure that such entity's 
proportionate interest in the Surviving Corporation immediately after the 
Merger is as it was in Orion immediately before the Merger. In addition, 
persons who hold (i) outstanding stock options to purchase shares of Orion 
Common Stock and (ii) outstanding warrants to purchase shares of Orion Common 
Stock will receive Loral stock options and warrants that will entitle them to 
receive a pre-determined amount of Loral Common Stock upon exercise of such 
options or warrants. 

   The formula in the Merger Agreement that determines the exact amount of 
Loral Common Stock that each Orion stockholder will receive in exchange 
(defined as the Exchange Ratio, see "The Merger Agreement -- Conversion of 
Orion Capital Stock") for their shares of Orion Capital Stock or upon 
exercise of their stock options or warrants depends on the trading prices of 
Loral Common Stock for a twenty day period that ends on the tenth trading day 
prior to the date of the Merger (defined as the Determination Price, see "The 
Merger Agreement -- Conversion of Orion Capital Stock"). The exact amount of 
Loral Common Stock that each Orion stockholder will receive, therefore, is 
not presently ascertainable. 

<PAGE>
   The following table, however, presents for each whole dollar Determination 
Price from $15 through $26, as well as for a Determination Price equal to 
$16.305, $20.3815 and $24.458 (the low, middle and high end of the 
Determination Price range), (i) the Exchange Ratio and (ii) the dollar value 
of each share of Loral Common Stock that Orion stockholders would receive in 
the Merger in exchange for shares of Orion Common Stock:

</TABLE>

   As the above table illustrates, so long as the Determination Price of 
Loral Common Stock remains between $16.305 and $24.458, the intended economic 
effect of the Merger is to provide Orion stockholders with $17.50 worth of 
Loral Common Stock in exchange for each share of Orion Common Stock. As the 
above table also illustrates, if the Determination Price of Loral Common 
Stock is greater than $24.458, or less than $16.305, Orion stockholders will 
receive a maximum of 1.07329 and a minimum of 0.71553 shares of Loral Common 
Stock in exchange for each share of Orion Common Stock, which would provide 
Orion stockholders with Loral Common Stock with a value that is greater than 
$17.50 (in the case of a Determination Price greater than $24.458) or less 
than $17.50 (in the case of a Determination Price less than $16.305). 

   The intended economic effect of the Merger is to provide each holder of an 
outstanding option or warrant to purchase Orion Common Stock with an option 
or warrant to acquire Loral Common Stock with the same terms and conditions 
that were applicable under such option or warrant prior to the Merger. 
Specifically, at the time of the Merger, each Orion option or warrant will be 
converted into a Loral option or warrant to acquire the number of whole 
shares of Loral Common Stock equal to the product of the aggregate number of 
shares of Orion Common Stock for which such Orion option or warrant was 
exercisable multiplied by the Exchange Ratio. The exercise price per share of 
Loral Common Stock issuable pursuant to each Orion option will be equal to 
the aggregate exercise price of such option or warrant at the time of the 
Merger divided by the number of shares of Loral Common Stock for which such 
option or warrant is exercisable as determined above and rounded to the next 
highest whole cent. No Orion option or warrant shall be exercisable for 
fractional shares. Instead, each holder of an Orion option or warrant 
exercisable for a fractional share of Loral Common Stock will be entitled to 
receive, upon exercise thereof, an offset against the aggregate exercise 
price of the option or warrant. For more detail on the treatment of Orion 
options and warrants in the Merger, stockholders should review the 
information provided under "The Merger -- Conversion of Options and Warrants; 
Stock Purchase Plan." 

   From February 23, 1998 until the date of the Merger, Orion stockholders 
can call (301) 721-2626 and listen to a recording of what the Exchange Ratio 
would be if the Merger occurred on the date of the phone call. A more 
detailed explanation of how the Determination Price and the Exchange Ratio 
are defined and calculated is set forth under the caption "The Merger 
Agreement -- Conversion of Orion Capital Stock." 

   As provided for in the Rights Agreement dated March 27, 1996 between Loral 
and The Bank of New York, as Rights Agent (the "Rights Agreement"), each 
share of Loral Common Stock issued in connection with the Merger will be 
accompanied by one Loral Right (a "Loral Right") to purchase from Loral a 
unit consisting initially of one one-thousandth of a share of Series B 
Preferred Stock, par value $.01 per share.

   Approval of the Merger Agreement shall constitute the approval of the 
specific terms therein and the transactions contemplated thereunder, 
including the Merger. Prior to voting on the Merger, Orion stockholders 
should review carefully the Merger Agreement, a copy of which is attached to 
this Proxy Statement/Prospectus as Attachment A and incorporated herein by 
reference. 

   This Proxy Statement/Prospectus provides a detailed description of the 
Merger, including Orion's and Loral's reasons for entering into the Merger 
Agreement and the effect of the Merger on Orion and its stockholders, and of 
the business and financial condition of Orion and Loral. 

   Amendments of Director Option Plan and Puente and Hauser Option 
Agreements. As indicated above, in the Merger each outstanding stock option 
to purchase shares of Orion Common Stock is to be converted into an option to 
acquire the number of shares of Loral Common Stock equal to the Exchange 
Ratio multiplied by the number of shares of Orion Common Stock for which such 
option was exercisable. In the case of the options granted under the Director 
Option Plan and the Puente and Hauser Option Agreements, Orion is seeking to 
effect the conversion of such options by amending the Director Option Plan 
and the Puente and Hauser Option Agreements. Orion also has amended its other 
stock option plans to effect such conversion, but amendment of such other 
plans does not require stockholder approval and accordingly is not one of the 
matters to be acted upon at the Special Meeting. 

   Orion also is proposing to amend the Director Option Plan to provide that 
options granted to Orion's directors that vest at the next annual meeting of 
stockholders of Orion instead would vest upon consummation of the Merger, if 
the Merger occurs prior to such annual meeting. Orion believes that since its 
directors will have performed nearly a full year of service since the last 
annual meeting of stockholders, and since such directors would be resigning 
prior to the next annual meeting of stockholders in order to satisfy a 
condition of the Merger, it is appropriate for the directors' options to vest 
upon consummation of the Merger. Copies of the proposed amendments to the 
Director Option Plan and the Puente and Hauser Option Agreements are attached 
to this Proxy Statement/Prospectus as Attachments D, E and F, respectively. 

   THE BOARD OF DIRECTORS OF ORION RECOMMENDS THAT STOCKHOLDERS VOTE FOR 
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT, AS DESCRIBED IN THIS PROXY 
STATEMENT/ PROSPECTUS. CERTAIN MEMBERS OF THE ORION BOARD OF DIRECTORS AND 
THEIR AFFILIATED COMPANIES HOLDING, IN THE AGGREGATE, APPROXIMATELY 32% OF 
THE VOTING STOCK OF ORION OUTSTANDING AS OF FEBRUARY 12, 1998, HAVE AGREED TO 
VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. IN ADDITION, SPACE 
SYSTEMS/LORAL, INC. ("SS/L"), A WHOLLY-OWNED SUBSIDIARY OF LORAL, HOLDS 
APPROXIMATELY 2.7% OF THE VOTING STOCK OF ORION OUTSTANDING AS OF FEBRUARY 
12, 1998, AND WILL VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. 

   THE BOARD OF DIRECTORS OF ORION ALSO RECOMMENDS THAT STOCKHOLDERS VOTE FOR 
APPROVAL OF EACH OF THE AMENDMENTS OF THE DIRECTOR OPTION PLAN AND THE PUENTE 
OPTION AGREEMENT AND HAUSER OPTION AGREEMENT. 

   SEE "RISK FACTORS" BEGINNING ON PAGE 22 FOR A DISCUSSION OF CERTAIN 
FACTORS THAT SHOULD BE CONSIDERED BY ORION STOCKHOLDERS. 

THE SECURITIES TO BE ISSUED IN THE MERGER HAVE NOT BEEN APPROVED OR 
DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES 
COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE 
SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY 
STATEMENT/ PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL 
                                   OFFENSE. 

       The date of this Proxy Statement/Prospectus is February 17, 1998.

                           FORWARD-LOOKING STATEMENTS

   This Proxy Statement/Prospectus includes forward-looking statements within

financial position, business strategies and plans, combinations of the Orion

respective expectations reflected in such forward-looking statements are 
based on reasonable assumptions, no assurance can be given that such 
expectations will be proven to have been correct. Important factors that 
could cause actual results to differ materially from the expectations 
reflected in the forward-looking statements herein include, among others, the

                                 Orion immediately before the Merger. In 
                                 addition, persons who hold (i) outstanding 
                                 stock options to purchase shares of Orion 
                                 Common Stock and (ii) outstanding warrants 
                                 to purchase shares of Orion Common Stock 
                                 will receive Loral stock options and 
                                 warrants that will entitle them to receive a 
                                 pre-determined amount of Loral Common Stock 
                                 upon exercise of such options or warrants. 

                                 The formula in the Merger Agreement that 
                                 determines the exact amount of Loral Common 
                                 Stock that each Orion stockholder will 
                                 receive in exchange (defined as the Exchange 
                                 Ratio, see "The Merger Agreement --

                                 exercise of their stock options or warrants 
                                 depends on the trading prices of Loral 
                                 Common Stock for a twenty day period that 
                                 ends on the tenth trading day prior to the 
                                 date of the Merger (defined as the 
                                 Determination Price, see "The Merger

                                 Stock"). The exact amount of Loral Common 
                                 Stock that each Orion stockholder will 
                                 receive, therefore, is not presently 
                                 ascertainable. The determination of the 
                                 numbers of shares is illustrated in the next 
                                 paragraph. Each share of Loral Common Stock 
                                 issued in connection with the Merger will be 
                                 accompanied by one Loral Right. No 
                                 fractional shares will be issued. The Merger 
                                 will become effective upon the filing of the 
                                 Certificate of Merger (as defined in the

                                 By way of illustration, if the Merger 
                                 occurred as of February 12, 1998 and all 
                                 Orion stockholders exchanged their Orion 
                                 stock (excluding treasury shares and shares 
                                 owned by Loral or its subsidiaries), there 
                                 would have been approximately 24,878,000 
                                 shares of Orion Common Stock exchanged for 
                                 Loral Common Stock. Based on assumed 
                                 Determination Prices of $15 and $26, the 
                                 approximately 24,878,000 shares of Orion 
                                 Common Stock would have been exchanged for 
                                 26,701,309 (representing a beneficial 
                                 ownership of approximately 13.3% of Loral 
                                 Common Stock) and 17,800,956 shares of Loral 
                                 Common Stock (representing a beneficial 
                                 ownership of approximately 8.9% of Loral 
                                 Common Stock), respectively. 

                                 From February 23, 1998 until the date of the 
                                 Merger, Orion stockholders can call (301) 
                                 721-2626 and listen to a recording of what 
                                 the Exchange Ratio would be if the Merger 
                                 occurred on the day of the phone call. 

Conversion of Orion Options 
and Warrants ..................  The intended economic effect of the Merger 
                                 is to provide each holder of an outstanding 
                                 option or warrant to purchase Orion Common 
                                 Stock with an option or warrant to acquire 
                                 Loral Common Stock with the same terms and 
                                 conditions that were applicable under such 
                                 option or warrant prior to the Merger. 
                                 Specifically, at the time of the Merger, 
                                 each Orion option or warrant will be 
                                 converted into a Loral option or warrant to 
                                 acquire the number of whole shares of Loral 
                                 Common Stock equal to the product of the 
                                 aggregate number of shares of Orion Common 
                                 Stock for which such Orion option or warrant 
                                 was exercisable multiplied by the Exchange 
                                 Ratio. The exercise price per share of Loral 
                                 Common Stock issuable pursuant to each Orion 
                                 option will be equal to the aggregate 
                                 exercise price of such option or warrant at 
                                 the time of the Merger divided by the number 
                                 of shares of Loral Common Stock for which 
                                 such option or warrant is exercisable as 
                                 determined above and rounded to the next 
                                 highest whole cent. No Orion option or 
                                 warrant shall be exercisable for fractional 
                                 shares. Instead, each

                                 exercisable for a fractional share of Loral 
                                 Common Stock will be entitled to receive, 
                                 upon exercise thereof, an offset against the 
                                 aggregate exercise price of the option or 
                                 warrant. Loral will file one or more 
                                 registration statements to become effective 
                                 as soon as practicable after the Merger with 
                                 respect to the Loral Common Stock subject to 
                                 options and warrants. For more detail on the 
                                 treatment of Orion options and warrants in 
                                 the Merger, stockholders should review the

                                 Preferred Stock shall no longer be 
                                 outstanding and shall automatically be 
                                 canceled and retired and shall cease to 
                                 exist, and each holder of a certificate 
                                 representing any shares of Orion Common 
                                 Stock and Orion Preferred Stock shall cease 
                                 to have any rights with respect thereto, 
                                 except the right to receive the shares of 
                                 Loral Common Stock issued in exchange 
                                 therefor upon the surrender of such

                                 Loral, and Orion will change its name to 
                                 Loral Orion Network Systems, Inc." See "The

Recommendation of Orion Board 
 of Directors .................  The Orion Board of Directors has approved 
                                 the terms of the Merger Agreement and 
                                 determined that the Merger Agreement and the 
                                 transactions contemplated thereunder, 
                                 including the Merger, are fair to, and in 
                                 the best interests of, Orion and its 
                                 stockholders. The Orion Board of Directors 
                                 unanimously recommends that Orion 
                                 stockholders vote "FOR" approval of the 
                                 Merger Agreement and the transactions 
                                 contemplated thereunder, including the 
                                 Merger. See "The Merger -- Background of the 
                                 Merger"; "The Merger -- Recommendation of 
                                 Orion Board of Directors; Orion's Reasons 
                                 for the Transactions"; and "The Merger -- 
                                 Interest of Certain Persons in the Merger." 

Orion's Reasons for the 
 Transactions .................  In reaching its determination, the Orion 
                                 Board of Directors considered a number of 
                                 factors, including: (i) the Orion Board of 
                                 Directors' desire to maximize stockholder 
                                 value; (ii) the failure of the market price 
                                 of Orion Common Stock to increase following 
                                 the January 1997 Transactions (as defined 
                                 below) and various factors putting downward 
                                 pressure on the market price of the Orion 
                                 stock; (iii) perceived limitations on 
                                 Orion's growth potential due to lack of 
                                 financial resources and limitations on 
                                 expanding through acquisitions due to the 
                                 market price of Orion Common Stock; (iv) the 
                                 competitive environment, including the trend 
                                 toward consolidation in the satellite 
                                 services industry and the Orion Board of 
                                 Director's belief that during the one to two 
                                 years before Orion 2 and Orion 3 would be 
                                 ready for launch and operation Orion's 
                                 ability to remain competitive would be 
                                 limited; (v) Orion's belief that the Merger 
                                 will expand its business opportunities, that 
                                 its international satellite business will 
                                 fit well with Loral's existing Skynet 
                                 business, that the Merger will enable Loral 
                                 and Orion collectively to take advantage of 
                                 more opportunities to expand than Orion 
                                 could pursue on its own, and that Orion will 
                                 have increased access to the capital markets 
                                 to provide financing for such opportunities; 
                                 (vi) Orion's belief that in comparison to 
                                 other potential transactions and strategies 
                                 the Merger represented the best opportunity 
                                 for increasing stockholder value; (vii) the 
                                 process followed by Morgan Stanley & Co. 
                                 Incorporated ("Morgan Stanley"), Orion's 
                                 financial advisor, in seeking an acquiror 
                                 for Orion; (viii) the opinion of Morgan 
                                 Stanley (discussed below); (ix) the per 
                                 share value based on the Exchange Ratio 
                                 being considerably above the market price 
                                 for shares of Orion Common Stock preceding 
                                 the commencement of the process of seeking 
                                 an acquiror; (x) the benefit to Orion 
                                 stockholders from becoming stockholders in a 
                                 larger, more diversified entity; (xi) the 
                                 business, financial condition and recent 
                                 results of operations of Orion, and 
                                 estimates of the prospects of Orion; (xii) 
                                 the terms of the Merger Agreement being 
                                 determined through arm's length 
                                 negotiations; (xiii) the effect of the 
                                 Merger on Orion's employees; (xiv) the terms

                                 Board of Directors' belief that the required 
                                 regulatory approvals could be obtained for 
                                 the Merger.

Opinion of Orion's Financial 
 Advisor ......................  Orion has received the opinion of Morgan 
                                 Stanley to the effect that, as of October 6, 
                                 1997, the Exchange Ratio is fair from a 
                                 financial point of view to the holders of 
                                 Orion Common Stock (other than Loral and its 
                                 affiliates) and, assuming the conversion of 
                                 the Orion Preferred Stock into Orion Common 
                                 Stock in accordance with their terms, to the 
                                 holders of Orion Preferred Stock. The full 
                                 text of the opinion of Morgan Stanley, which 
                                 sets forth the assumptions made, procedures 
                                 followed, matters considered and limitations 
                                 on the review undertaken, is attached hereto 
                                 as Attachment C. Each Orion stockholder 
                                 should read such opinion carefully in its 
                                 entirety. The opinion of Morgan Stanley is 
                                 directed only to the matters set forth 
                                 therein and does not constitute an opinion 
                                 or recommendation as to how the stockholders 
                                 of Orion should vote at the Special Meeting 
                                 and, with respect to the holders of Orion 
                                 Preferred Stock, whether such holders should 
                                 convert their shares of Orion Preferred 
                                 Stock into Orion Common Stock. See "The 
                                 Merger -- Opinion of Orion's Financial 
                                 Advisor." 

Loral's Reasons for the 
Transactions. .................  Loral is undertaking the Merger in 
                                 furtherance of its long-term strategy to 
                                 expand the range of its geosynchronous 
                                 satellite service businesses 
                                 internationally. Orion's business was deemed 
                                 an attractive acquisition candidate because 
                                 of the orbital location of Orion 1 and the 
                                 proposed locations for the Orion satellites 
                                 under construction, the experience of Orion 
                                 management and personnel in European 
                                 operations, the expertise of Orion in value 
                                 added satellite services and 
                                 satellite-supported data networking, all of 
                                 which, Loral believes, will complement the 
                                 businesses of Skynet and CyberStar. Loral 
                                 also believes that the business of Orion 
                                 will benefit from the market position and 
                                 marketing expertise of Skynet, the 
                                 technological expertise of SS/L and the 
                                 financial resources of Loral. 

Exchange of Certificates 
 in the Merger ................  Loral shall, on behalf of Merger Subsidiary, 
                                 deposit with The Bank of New York (the 
                                 "Exchange Agent"), the shares of Loral 
                                 Common Stock issuable pursuant to the Merger 
                                 Agreement plus cash in an amount sufficient 
                                 to make payment for fractional shares. 
                                 Promptly after the Effective Time, the 
                                 Exchange Agent will mail a transmittal

                                 prior to the Effective Time represented 
                                 outstanding shares of Orion Capital Stock. 
                                 Upon surrender to the Exchange Agent of a

                                 shares of Orion Capital Stock, together with 
                                 such letter of transmittal duly executed,

                                 shall forthwith be canceled. ORION

                                 exercised as of such last trading day of 
                                 Orion Common Stock. See "The Merger --

Interest of Certain Persons 
 in the Merger ................  Certain members of Orion's management and 
                                 Board of Directors have certain interests in 
                                 the Merger that are in addition to the 
                                 interests of stockholders of Orion 
                                 generally. These interests arise from, among 
                                 other things, certain employee benefit 
                                 plans, and indemnification and insurance 
                                 arrangements which Loral will assume or has 
                                 agreed to provide after the Merger. As of 
                                 the Record Date, directors and executive 
                                 officers of Orion owned (i) 2,363,698 shares 
                                 of Orion Common Stock and 1,454 shares of 
                                 Orion Preferred Stock (for which they will 
                                 receive the same consideration as other 
                                 Orion stockholders) and (ii) options to 
                                 acquire 901,236 shares of Orion Common 
                                 Stock. See "The Merger -- Interests of 
                                 Certain Persons in the Merger." Under the 
                                 proposed amendments to the Director Option 
                                 Plan, options issued to Orion's directors 
                                 under the Director Option Plan will vest 
                                 upon consummation of the Merger instead of 
                                 at the next annual meeting of Orion 
                                 stockholders. See "Amendments to Director 
                                 Option Plan." Certain directors and their 
                                 affiliated companies holding, in the 
                                 aggregate, approximately 32% of the voting 
                                 stock outstanding as of February 12, 1998 
                                 have entered into the Principal Stockholder 
                                 Agreement with Loral. In addition, SS/L 
                                 owned, as of February 12, 1998, 588,235 
                                 shares of Orion Common Stock, equal to 
                                 approximately 2.7% of the voting stock 
                                 outstanding as of such date, and will vote 
                                 for approval and adoption of the Merger 
                                 Agreement. See "The Merger Agreement and 
                                 Principal Stockholder Agreement -- The 
                                 Principal Stockholder Agreement." 

Fees and Expenses .............  All fees and expenses incurred in connection 
                                 with the Merger, the Merger Agreement and 
                                 the transactions contemplated thereunder 
                                 shall be paid by the party incurring such 
                                 fees or expenses, whether or not the Merger 
                                 is consummated. See "The Merger -- Fees and 
                                 Expenses." 

Accounting Treatment ..........  The Merger will be accounted for using the 
                                 purchase method of accounting. See "The 
                                 Merger -- Accounting Treatment." 

Certain U.S. Federal Income Tax 
 Consequences of the Merger ...  The tax treatment of the Merger is uncertain 
                                 due to special considerations under Section 
                                 367 of the Internal Revenue Code, as amended 
                                 (the "Code") because of Loral's status as a 
                                 foreign corporation. Subject to such 
                                 considerations, Orion and Loral expect that 
                                 the Merger would constitute a 
                                 "reorganization" within the meaning of 
                                 Section 368(a) of the Code and that for

                                 U.S. federal income tax purposes no gain or 
                                 loss would be recognized by U.S. 
                                 stockholders of Orion upon the receipt of 
                                 Loral Common Stock in exchange for Orion 
                                 Common Stock or Orion Preferred Stock 
                                 pursuant to the Merger (except with respect 
                                 to the receipt of cash by a holder of Orion 
                                 Common Stock or Orion Preferred Stock in 
                                 lieu of a fractional share interest in Loral 
                                 Common Stock). However, these special 
                                 considerations because of Loral's status as 
                                 a foreign corporation may result in the 
                                 Merger not constituting a "reorganization" 
                                 within the meaning of Section 368(a) of the 
                                 Code, so that for U.S. federal income tax 
                                 purposes any gain (but not loss) realized 
                                 would be recognized by U.S. stockholders of 
                                 Orion upon the receipt of Loral Common Stock 
                                 in exchange for Orion Common Stock or Orion 
                                 Preferred Stock pursuant to the Merger. Such 
                                 gain would be in an amount equal to the 
                                 excess, if any, of the fair market value of 
                                 the Loral Common Stock received over the 
                                 Orion stockholders' adjusted tax basis in 
                                 the Orion Common Stock or Orion Preferred 
                                 Stock exchanged therefor. Orion and Loral 
                                 are seeking a private letter ruling from the 
                                 Internal Revenue Service ("IRS") regarding 
                                 Loral's status as a corporation under 
                                 Section 367 of the Code and, therefore, 
                                 whether the Merger is eligible to qualify as 
                                 a reorganization under Section 368(a) of the 
                                 Code. THERE CAN BE NO ASSURANCE THAT A 
                                 FAVORABLE IRS RULING WILL BE OBTAINED OR 
                                 THAT ORION STOCKHOLDERS WILL NOT BE REQUIRED 
                                 TO RECOGNIZE ANY GAIN REALIZED FOR U.S. 
                                 FEDERAL INCOME TAX PURPOSES AS A RESULT OF 
                                 THE MERGER. See "The Merger -- Certain U.S. 
                                 Federal Income Tax Consequences of the 
                                 Merger." 

Resale of Loral Common Stock ..  The Loral Common Stock to be issued pursuant 
                                 to the Merger will be freely transferable 
                                 under the Securities Act except for shares 
                                 issued to any Orion stockholder who, prior 
                                 to the Merger, may be deemed an "Affiliate" 
                                 under the Securities Act. Orion will use its 
                                 reasonable efforts to cause each Affiliate 
                                 to enter into an agreement with Loral 
                                 providing that such Affiliate will not 
                                 transfer any Loral Common Stock received in 
                                 the Merger except in compliance with the 
                                 Securities Act. See "The Merger -- Resale of 
                                 Loral Common Stock." 

Listing .......................  The shares of Loral Common Stock to be 
                                 issued in connection with the Merger will be 
                                 authorized for listing on the New York Stock 
                                 Exchange ("NYSE"). See "The Merger --

Principal Stockholder Agreement 
 ...............................  The Principal Stockholder Agreement, dated 
                                 as of October 7, 1997, as amended and 
                                 restated as of December 1, 1997, among 
                                 Orion, Loral, Merger Subsidiary and certain 
                                 principal stockholders of Orion, consisting 
                                 of certain directors of Orion and their 
                                 affiliated companies. Such principal 
                                 stockholders collectively hold approximately 
                                 32% of the Orion voting stock outstanding as 
                                 of the Record Date for the Special Meeting. 
                                 As a condition to entering into the Merger 
                                 Agreement, Loral required such principal 
                                 stockholders to enter into the Principal

                                 restated to make certain technical 
                                 corrections), pursuant to which such 
                                 stockholder parties (i) have agreed to vote 
                                 all of their shares of Orion Capital Stock 
                                 in favor of the Merger and the Merger 
                                 Agreement and against competing 
                                 transactions. Such stockholders also granted 
                                 Loral an irrevocable option to purchase all 
                                 (but not less than all) of their shares of 
                                 Orion Capital Stock for an exercise price 
                                 equal to the number of shares of Orion 
                                 Capital Stock to be purchased by Loral 
                                 multiplied by the Exchange Ratio. The option 
                                 will become exercisable in whole (but not in 
                                 part) upon the occurrence of the following 
                                 events or transactions: (a) the Board of 
                                 Directors of Orion or any committee thereof

                                 approval or recommendation of the Merger or 
                                 the Merger Agreement in any manner adverse 
                                 to Loral, or approved or recommended any

                                 Agreement by the stockholders of Orion shall 
                                 not have been obtained by reason of the 
                                 failure to obtain the required vote at the 
                                 Special Meeting and (ii) at the time of such 
                                 negative vote there shall be pending an

                                 its subsidiaries shall have entered into any 
                                 agreement with any person (other than Loral

                                 shall have publicly 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 
                                 Orion or of 20% or more (in fair market 
                                 value) of the assets of Orion and its 
                                 subsidiaries, on a consolidated basis,

                                 Act), other than Loral or any of its 
                                 affiliates, of beneficial ownership of (as 
                                 defined in the Rule 13d-3 under the Exchange 
                                 Act), or the right to acquire beneficial 
                                 ownership of, securities representing 35% or 
                                 more of the voting power of Orion. Orion and 
                                 Loral are currently contemplating an 
                                 amendment to the Principal Stockholder 
                                 Agreement that would permit BAe (as defined 
                                 herein) to convert its Debentures (as 
                                 defined herein) into 3,571,429 shares of 
                                 Orion Common Stock and sell such shares 
                                 prior to the Effective Date of the Merger. 
                                 In addition, SS/L is contemplating the sale 
                                 of the 588,235 shares of Orion Common Stock 
                                 it owns prior to Effective Date of the 
                                 Merger. Any such sales would take place 
                                 following the Record Date, and the right to 
                                 direct the voting of such shares would not 
                                 be transferred. See "The Merger Agreement 
                                 and Principal Stockholder Agreement -- The 
                                 Principal Stockholder Agreement."

                                 its business plan. See "The Merger Agreement 
                                 and Principal Stockholder Agreement -- The

                                 either Orion or Loral if the other has

                                 warranty made by such other party is

                                 breach or misrepresentation is not cured 
                                 within thirty (30) days after notice thereof 
                                 and such breach or misrepresentation results 
                                 in a material adverse effect; (iii) by 
                                 either Orion or Loral if any action by any

                                 or Loral if the Merger has not been

                                 Agreement and Principal Stockholder 
                                 Agreement -- The Merger Agreement -- 
                                 Termination; Amendment." 

Termination Fee ...............  Orion has agreed to pay Loral a termination 
                                 fee of $20 million (the "Termination Fee") 
                                 in the event that Loral or Orion terminates

                                 Orion's Board of Directors withdrawing or 
                                 modifying its approval of the Merger

                                 proposal or (ii) pursuant to a failure to 
                                 receive the requisite Orion stockholder 
                                 approval of the Merger Agreement when 
                                 another acquisition proposal is pending, and 
                                 within one year after such termination Orion 
                                 consummates a business combination or the 
                                 sale of 30% or more of Orion's voting

AMENDMENTS TO DIRECTOR OPTION 
 PLAN, PUENTE AND HAUSER 
 OPTION AGREEMENTS 

The Amendments ................  The amendments to the Puente and Hauser 
                                 Option Agreements and certain of the 
                                 amendments to the Director Option Plan would 
                                 effect the conversion provided for in the 
                                 Merger Agreement, so that in the Merger each 
                                 outstanding stock option to purchase shares 
                                 of Orion Common Stock will be converted into 
                                 an option to acquire the number of shares of 
                                 Loral Common Stock equal to the Exchange 
                                 Ratio multiplied by the number of shares of 
                                 Orion Common Stock for which such option was 
                                 exercisable. Other amendments to the 
                                 Director Option Plan provide that options 
                                 granted to Orion's directors that vest at 
                                 the next annual meeting of stockholders of 
                                 Orion instead would vest upon consummation 
                                 of the Merger, if the Merger occurs prior to 
                                 such annual meeting. 

Purpose of the Amendments .....  In the Merger each outstanding stock option 
                                 to purchase shares of Orion Common Stock 
                                 will be converted into an option to acquire 
                                 Loral Common Stock based upon the Exchange 
                                 Ratio. Orion is seeking to effect the 
                                 conversion of certain options by amending 
                                 the Director Option Plan and the Puente and 
                                 Hauser Option Agreements. Orion also has 
                                 amended its other stock option plans to 
                                 effect such conversion, but amendment of 
                                 such other plans does not require 
                                 stockholder approval and accordingly is not 
                                 one of the matters to be acted upon at the 
                                 Special Meeting. With regard to the vesting 
                                 of options held by Orion's directors, Orion 
                                 believes that since its directors will have 
                                 performed nearly a full year of service 
                                 since the last annual meeting of 
                                 stockholders, and since such directors would 
                                 be resigning prior to the next annual 
                                 meeting of stockholders to satisfy a 
                                 condition of the Merger, it is appropriate 
                                 for the directors' options to vest upon 
                                 consummation of the Merger. 

Recommendations of Orion Board 
of Directors ..................  The Orion Board of Directors has unanimously 
                                 approved the amendments to the Director 
                                 Option Plan and to the Puente and Hauser 
                                 Option Agreements and determined that these 
                                 amendments are in the best interests of 
                                 Orion and its stockholders. The Board 
                                 recommends unanimously that stockholders 
                                 vote FOR the amendments to the Director 
                                 Option Plan, FOR the amendments to the 
                                 Puente Option Agreement and FOR the 
                                 amendments to the Hauser Option Agreement. 

RISK FACTORS 

   In considering whether to approve the Merger and the other matters set 
forth in this Proxy Statement/Prospectus, Orion stockholders should consider, 
in addition to the other information set forth in this Proxy 
Statement/Prospectus, the matters described under "RISK FACTORS," including 
the following summarized risk factors. The section captioned "RISK FACTORS" 
should, however, be reviewed by Orion stockholders in its entirety. 

                                       19
<PAGE>
Tax Treatment Uncertain .......  The tax treatment of the Merger is uncertain 
                                 due to special considerations because of 
                                 Loral's status as a foreign corporation. 

Exchange Ratio Adjustments ....  Limitations on adjustments to the Exchange 
                                 Ratio and the possibility that the 
                                 Determination Price may be different than 
                                 the market price of the Loral Common Stock. 

Offer to Purchase .............  Consummation of the Merger will require 
                                 Orion to offer to purchase bonds issued by 
                                 Orion in January 1997 at a purchase price 
                                 equal to 101% of their principal amount 
                                 (approximately $752 million if the offer to 
                                 purchase had occurred as of January 30, 
                                 1998). 

Satellite Industry ............  Special technical and regulatory risks 
                                 associated with the satellite industry. 

Financial Risks; Leverage .....  At September 30, 1997, Loral's outstanding 
                                 long-term debt was $231.5 million. In 
                                 addition, at September 30, 1997, Loral had 
                                 outstanding Series C Preferred Stock having 
                                 a redemption value of $747.3 million, which 
                                 will be payable at Loral's option, in cash, 
                                 common stock or a combination thereof. For 
                                 the nine months ended September 30, 1997, 
                                 Loral had a deficiency of earnings to cover 
                                 fixed charges of $13.6 million. Following 
                                 consummation of the Merger, Orion will 
                                 continue to have outstanding approximately 
                                 $710.4 million of publicly traded debt 
                                 before interest accretion of $22.1 million 
                                 and unamortized discount of $9.0 million at 
                                 September 30, 1997. 

Conflicts of Interest .........  Possible conflicts of interest resulting 
                                 from, among other things, Loral's ownership 
                                 interests in Globalstar and SatMex. 

Loral/Orion Integration .......  The integration of Loral and Orion could 
                                 cause the interruption of, or a disruption 
                                 in, the activities of either or both of the 
                                 companies' businesses and have a material 
                                 adverse effect on future combined 
                                 operations. 

Dependence on SS/L ............  Currently, SS/L generates a significant 
                                 portion of Loral's revenue and operating 
                                 income. Loral intends to capitalize on 
                                 SS/L's capabilities, market position and 
                                 advanced technologies to identify and 
                                 develop additional space-based 
                                 communications services opportunities There 
                                 can be no assurance that current or future 
                                 satellite-based ventures entered into by 
                                 Loral will result in revenues or operating 
                                 income that will materially reduce its 
                                 dependence on SS/L.

(2) Loral was formed to effectuate the distribution of Loral Corporation's 
    ("Old Loral") space and telecommunications businesses (the 
    "Distribution") to shareholders of Old Loral and holders of options to 
    purchase Old Loral common stock pursuant to a merger agreement dated 
    January 7, 1996 between Loral and Lockheed Martin Corporation ("Lockheed 
    Martin"). The Distribution of approximately 183.6 million shares of Loral 
    Common Stock was made on April 23, 1996. Old Loral's fiscal year end was 
    March 31. Loral adopted a December 31 year end and its first fiscal 
    quarter ended on June 30, 1996. Accordingly, data reflects Loral 
    financial data for the nine months ended September 30, 1997 (interim 
    period) and for the nine months ended December 31, 1996 (fiscal year). 
    Data for Orion, accordingly, also reflects the nine months ended December 
    31, 1996.

                                 RISK FACTORS 

   The following risk factors should be carefully considered by Orion 
stockholders in deciding whether to approve and adopt the Merger Agreement. 

                      RISKS RELATED TO THE TRANSACTIONS 

TAX TREATMENT UNCERTAIN DUE TO SPECIAL CONSIDERATIONS 

   The tax treatment of the Merger is uncertain due to special considerations 
because of Loral's status as a foreign corporation. Loral and Orion are 
seeking a private letter ruling from the IRS with respect to whether Loral 
will be treated as a corporation for U.S. federal income tax purposes. The 
ruling request to be submitted to the IRS deals with the length of time that 
Loral has directly or indirectly conducted an active business outside the 
United States. The tax issues are highly technical and no comparable ruling 
has ever been issued. The receipt of a favorable ruling is not a condition to 
the Merger. There can be no assurance that a favorable ruling will be 
received. Unless and until a favorable ruling is received, Loral intends to 
treat the Merger as a taxable transaction and, accordingly, Orion 
stockholders will be required to recognize any gain (and will not be entitled 
to recognize any loss) realized for U.S. federal income tax purposes as a 
result of the Merger. See "The Merger -- Certain U.S. Federal Income Tax 
Consequences of the Merger." 

LIMITATION ON ADJUSTMENTS TO EXCHANGE RATIO; DETERMINATION PRICE MAY BE 
DIFFERENT THAN MARKET VALUE 

   The Exchange Ratio adjusts based on the Determination Price of Loral 
Common Stock. If the Determination Price is less than $24.458 but greater 
than $16.305 (the "Pre-established Range"), the Exchange Ratio is the 
quotient obtained by dividing $17.50 by the Determination Price. As a result, 
if Loral Common Stock is generally trading within the Pre-established Range 
the holders of Orion Capital Stock will receive in the Merger an amount of 
Loral Common Stock equal to approximately $17.50 for each share of Orion 
Capital Stock. 

   However, if the Determination Price is at or outside of the 
Pre-established Range, holders of Orion Capital Stock will receive instead a 
fixed number of shares of Loral Common Stock, obtained by dividing $17.50 by 
the high or low end of the Pre-established Range, as applicable. As a result, 
if the Determination Price is equal to or less than $16.305, the Exchange 
Ratio is determined by dividing $17.50 by $16.305, instead of by the 
Determination Price, with the result that the amount of Loral Common Stock 
received by holders of Orion Capital Stock in such event will likely be less 
than $17.50 for each share of Orion Capital Stock. 

   The Determination Price will equal the average of the volume-weighted 
average trading prices of Loral Common Stock for the twenty consecutive 
trading days on which trading of Loral Common Stock occurs ending the tenth 
trading day immediately prior to the closing date for the Merger. The 
Determination Price therefor will likely be greater or less than the market 
price of the Loral Common Stock at the Effective Time, so that even if the 
Determination Price is within the Pre-established Range the Loral Common 
Stock to be issued in the Merger may not have a market value of $17.50 per 
share. 

OFFER TO PURCHASE ORION'S SENIOR NOTES AND SENIOR DISCOUNT NOTES 

   Consummation of the Merger will constitute a "change of control" of Orion 
as defined in the Indentures (the "Indentures") pursuant to which $445 
million principal amount of Orion's 11 1/4% Senior Notes due 2007 (the 
"Senior Notes") and $265.4 million principal amount of Orion's 12 1/2% Senior 
Discount Notes due 2007 (the "Senior Discount Notes" and together with the 
Senior Notes, the "Notes") were outstanding as of September 30, 1997. 
Pursuant to the Indentures, within 30 business days after the Merger is 
consummated, Orion will be required to make an offer to purchase the Notes at 
a purchase price equal to 101% of their principal amount (approximately $752 
million if the offer to purchase had occurred as of January 30, 1998), plus 
accrued interest from the most recent interest payment date to the 

                                       22
<PAGE>
payment date. Because the Notes have traded in recent periods at prices above 
101% of their principal amount, Orion does not currently anticipate that the 
holders of a material principal amount of Notes will accept the offer to 
repurchase. 

   The Merger Agreement does not obligate Loral to assume or guarantee the 
Notes. Following the Merger, Loral will not be responsible for the Notes and 
Orion, as a wholly owned subsidiary of Loral, will remain responsible for 
principal and interest payments on the Notes. 

                     RISKS RELATED TO LORAL'S BUSINESSES 

   An investment in Loral and its subsidiaries as listed in the chart 
included below under the heading "Information About Loral" on page 34 (the 
"Loral Group") carries with it risks due to special financial, technical and 
regulatory factors. The risks are accentuated by the possibility of a number 
of them being realized at the same time. This is a summary of such factors. 

RISKS OF OPERATIONS IN THE SPACE ENVIRONMENT 

   Satellites operate in a distant, hostile environment. Despite costly high 
reliability parts and significant on ground testing to assure reliability for 
their designed lives, satellites remain vulnerable to complete or partial 
failure or degradation from hazards which include space debris, solar and 
other astronomical events, acts of war and component failure. Repair of 
satellites in space is not practicable. In addition, a number of factors 
affect the useful lives of Globalstar's, Skynet's, SatMex's and Orion's 
satellites, including the quality of construction, expected gradual 
environmental degradation of solar panels and the durability of component 
parts. Random failure of satellite components could result in damage to or 
loss of a satellite ("cold failures"). 

   The first-generation Globalstar satellite constellation (including spares) 
is designed to operate at full performance for a minimum of 7 1/2 years, 
after which performance is expected to gradually decline. However, there can 
be no assurance of the constellation's useful life. Globalstar anticipates 
using funds from operations to develop a second generation of satellites. If 
sufficient funds from operations are not available and Globalstar is unable 
to obtain financing for the second-generation constellation, Globalstar will 
not be able to deploy a second-generation constellation to replace 
first-generation satellites at the end of their useful lives. 

   In November 1995, an Orion 1 component supporting nine transponders 
serving the European portion of Orion 1's footprint experienced an anomaly 
that resulted in a service interruption lasting approximately two hours. Full 
service was restored using redundant equipment. These transponders generate a 
majority of Orion's revenues. Orion believes, based on Orion's own 
investigations and the manufacturer's, and based upon advice from Orion's 
engineering consultant that because the redundant component is functioning in 
accordance with specifications and the performance record of similar 
components is strong, the anomalous behavior is unlikely to affect the 
expected performance of the satellite over its useful life. There has been no 
further effect on Orion's ability to service customers. However, if the 
currently operating component fails, Orion 1 would experience a significant 
loss of usable capacity, resulting in lost service and a corresponding 
adverse effect on Orion's results of operations. 

   In 1994 and 1997 (prior to the acquisition by Loral), Skynet experienced 
the loss of its Telstar 402 and Telstar 401 satellites, respectively, 
resulting in lost service and a corresponding adverse effect on Skynet's 
results of operations. 

   Certain of SS/L's contracts provide that a portion of the total contract 
price is payable in the form of "incentive" payments earned during the life 
of the satellite in orbit as its mission is performed. Although SS/L 
generally receives the present value of such incentive payments in the event 
of launch failure or one caused by customer error, it forfeits such revenues 
if the loss is caused by system failure or an error on its part. While 
insurance against loss of such payments has been available in the past, its 
cost and availability are subject to substantial fluctuations. In addition, 
SS/L is prohibited under agreements with certain of its customers from 
insuring its orbital incentives. Certain of SS/L's contracts call for 
on-orbit delivery, allocating launch risk to SS/L. It is SS/L's intention to 
obtain insurance for that exposure. 

                                       23
<PAGE>
However, SS/L cannot predict whether, and there can be no assurance that, 
insurance against launch failure and loss of incentive payments will continue 
to be available on reasonable terms. 

LAUNCH RISK AND VEHICLE ACCESS 

   About 15% of commercial satellite launches have historically resulted in 
loss before the payload reaches its planned orbit ("hot failures"). While the 
Loral Group ordinarily obtains insurance against loss due to hot failures, 
such events can nevertheless disrupt and delay business schedules and cause 
substantial uninsured losses above and beyond the insured cost of the lost 
satellite. The Loral Group's ability to place satellites in orbit, and SS/L's 
ability to perform its on-orbit delivery contracts depend on the availability 
of launch vehicles and the requisite insurance. Launch slots are limited, and 
the launch insurance market has been subject to considerable fluctuation. 
Different launch facilities and vehicles have different success records, but 
the Loral Group, for business or scheduling reasons does not always use, or 
have available to it, the most successful facilities and vehicles for its 
launches. The cost and availability of launch insurance varies from time to 
time so there is no assurance that such insurance will shield every future 
loss. Moreover, the availability of launches from the republics of the former 
Soviet Union and the People's Republic of China are affected by U.S. 
government policies and international agreements. Changes in governmental 
policies or political leadership in the United States, Russia, Kazakhstan or 
China could affect the Loral Group's ability to launch from these countries. 

LEVERAGE OF LORAL GROUP 

   Many of the Loral Group's businesses are capital intensive, requiring high 
initial investments in the expectation of future revenues requiring 
relatively low marginal costs. At September 30, 1997, Loral's outstanding 
long-term debt was $231.5 million. In addition, Loral had outstanding at 
September 30, 1997 series C preferred stock having a redemption value of 
$747.3 million, which may be payable at Loral's option in cash, common stock 
of Loral or a combination thereof. For the nine months ended September 30, 
1997, Loral had a deficiency of earnings to cover fixed charges of $13.6 
million. Loral's Skynet and SS/L subsidiaries have recently consummated an 
$850 million credit facility. SS/L will also require continuous investment to 
maintain its technological position and the fixed satellite service 
businesses are at the beginning of a planned expansion. Following 
consummation of the Merger, Orion will continue to have outstanding, 
approximately $710.4 million of publicly-traded debt before interest 
accretion of $22.1 million and unamortized discount of $9.0 million at 
September 30, 1997. 

   In December 1997, a joint venture company ("SatMex Holdings") owned by 
Loral and Telefonica Autrey, S.A. de C.V. ("Telefonica Autrey) completed the 
acquisition of 75% of the outstanding stock of SatMex from the Mexican 
Government for $651.4 million (including installment interest). Loral and 
Telefonica Autrey hold 65% and 35%, respectively, of the economic interests, 
and 49% and 51% of the voting interests, respectively, in SatMex Holdings. 
SatMex currently has $645 million of outstanding indebtedness related to the 
acquisition and the construction and launch of a new SatMex satellite and has 
an additional $125 million available under a bank credit facility for 
completion of the satellite and for working capital purposes, which 
indebtedness and credit facility are non-recourse to Loral. In consideration 
for the assumption by SatMex of the debt incurred in connection with the 
acquisition, Servicios Corporativos Satelitales S.A. de C.V., a subsidiary of 
SatMex Holdings, issued to the Mexican Government a note having an initial 
principal amount of $125.1 million, with interest payable at maturity 
accreting at a rate of 6.03% per annum and maturing on December 30, 2004 (the 
"Government Obligation"). In order to guarantee payment of the Government 
Obligation upon maturity, Loral SatMex Ltd. ("LoralSat"), an indirect 
subsidiary of Loral, and Ediciones Enigma, S.A. de C.V. ("Ediciones"), a 
subsidiary of Telefonica Autrey, have deposited into a collateral trust their 
shares in SatMex Holdings and have agreed that they will, at all times during 
the three-year period ended December 29, 2000, maintain collateral in favor 
of the Mexican Government having a value equal to the Government Obligation, 
including all interest accrued thereon, and thereafter and until the maturity 
of the Government Obligation, a value equal to 1.2 times the Government 
Obligation, including all interest accrued thereon. In order to induce 
certain parties to enter into financing arrangements with SatMex, including a 
$450,000,000 senior secured credit facility and the placement of $320,000,000 
aggregate principal amount 

                                       24
<PAGE>
of high yield bonds, Loral entered into a letter agreement dated December 29, 
1997 whereby it and Telefonica Autrey agreed to ensure compliance by LoralSat 
and Ediciones of their obligations to maintain certain collateral in favor of 
the Mexican Government, for so long as (A) there remain any undrawn 
commitments or amounts outstanding under SatMex's senior secured credit 
facility (or certain secured notes to be issued to refinance a portion of the 
senior secured credit facility) or (B) there remain outstanding any of the 
high yield bonds. Each of Loral and Telefonica Autrey have agreed to share 
this obligation in proportion to their respective economic interests in 
SatMex Holdings. Loral accounts for its investment in SatMex Holdings using 
the equity method. 

   Globalstar, of which Loral currently owns directly and indirectly, on a 
fully diluted basis, approximately 39%, is still in the development stage. At 
September 30, 1997, Globalstar had outstanding long-term indebtedness of 
$1,266.7 million. In addition, on October 29, 1997, Globalstar issued $325 
million of 10 3/4% Senior notes due 2004. The foregoing indebtedness is 
non-recourse to Loral. 

   The Loral Group is therefore subject to substantial financial risks in the 
face of possible delays or reductions in revenue realization, unforeseen 
capital requirements or unanticipated expenses attributable to the factors 
described in this document. Such risks could result not only in adverse 
financial results due to ongoing debt service charges, but also in the 
necessity for additional financing which could result in increased debt and 
debt service costs, potential dilution of equity interests resulting from 
issuances of debt or equity, rights to distributions senior to those of the 
holders of Loral Common Stock, and covenants restricting distributions to 
holders of Loral Common Stock. 

OBSOLESCENCE DUE TO RAPID TECHNOLOGICAL CHANGE 

   In common with all high technology enterprises, the Loral Group's 
businesses are subject to obsolescence due to new technological developments. 
The rapid pace of technological change exposes the Loral Group to risk of 
loss due to the deployment of superior technologies by competitors. The Loral 
Group is also dependent upon technologies developed by third parties to 
implement key aspects of its strategy to integrate its satellite systems with 
terrestrial networks. SS/L, SkyNet, SatMex, Orion and Globalstar, in 
particular, are susceptible to such risks. As land-based telecommunications 
services expand, demand for certain types of satellite-based services may be 
reduced. New technology used by competitors could render Skynet, Globalstar, 
SatMex or Orion less competitive by satisfying consumer demand in alternative 
ways or through the use of incompatible telecommunications standards. In 
addition, SS/L's success depends on its ability to introduce innovative new 
products and services on a cost-effective and timely basis. 

THE GLOBALSTAR SYSTEM 

   Loral currently owns directly and indirectly, on a fully diluted basis, 
approximately 39% of Globalstar. The Globalstar System will consist of 56 
satellites (including 8 in-orbit spares) in low earth orbit together with 
ground facilities in numerous remote and sometimes primitive regions. Its 
operating facilities will be in more than 100 countries, many of which are 
based on emerging economies, eventually connecting hundreds of thousands of 
mobile and fixed telephone handsets. While Loral believes that each component 
of the Globalstar System, and the Globalstar System as a whole, is capable of 
performing as designed, no such complex, dispersed space/earth communications 
network has ever been operated commercially. Until the Globalstar System has 
operated as a whole in its actual space/earth environment, there can be no 
assurance that losses due to delays, failures and unforeseen additional costs 
will not occur. Globalstar's financial objectives are, in part, based on 
estimates as to the potential market for Globalstar System services and the 
price that users will be willing and able to pay, which cannot be practically 
validated until commercial operations have begun. There can be no assurance 
that such economic assumptions are justified. 

   Globalstar is not scheduled to begin commercial operations until the first 
quarter of 1999. Successful commencement of operations will require 
successful implementation of each of the elements of the Globalstar System -- 
space and ground segments, digital communications technology, user terminal 
supply, service provider arrangements and licensing. Globalstar launched 4 
satellites on February 14, 1998 

                                       25
<PAGE>
and expects to launch an additional 40 satellites during 1998 and 12 
satellites in early 1999. The initial launch was delayed from November 1997 
to February 1998 to allow for further testing and rehearsals of the tracking, 
telemetry and control (TT&C) ground equipment that monitors the launch and 
deployment of the Globalstar satellites. The postponement was adopted in 
order to assure an adequate period of time to complete testing of 
Globalstar's TT&C function prior to the initial launch and was not related to 
any segment performance issue. There can be no assurance that additional 
schedule delays will not occur. 

   Loral's equity in net loss attributable to its interest in Globalstar for 
the nine months ended September 30, 1997 was $24.3 million as compared to 
$18.1 million for the nine months ended December 31, 1996. Globalstar is 
expending significant funds for the construction, testing and deployment of 
the Globalstar System and such losses are expected to continue through 
commencement of revenue generating service operations. 

COMPETITION 

   Each of the Loral Group's businesses is subject to intense competition 
from entities, including several of the world's largest corporations, as well 
as governments and quasi-governmental organizations, which are larger and 
which may bring greater financial and operating resources to bear in 
competing as to marketing, regulation and technology. The Loral Group 
competes for customers and for local regulatory approval in jurisdictions in 
which both the Loral Group and a competing party may wish to operate. In 
addition, the Loral Group competes for allocation of scarce frequency 
assignments and geosynchronous orbital slots. Competition comes not only from 
entities carrying on the same activities as the Loral Group, but from others 
using alternative technologies such as terrestrial telecommunications and 
cable television, which themselves are constantly pursuing advanced 
technologies in order to enhance their competitive positions. In addition, as 
the Loral Group expands into international markets, it will have to compete 
with international operators including Intelsat and PanAmSat. To the extent 
that these entities offer products and services which are more sophisticated, 
efficient or reliable than those of the Loral Group, there could be a 
material adverse effect on the financial condition or results of operations 
of the Loral Group. 

COMPETITIVE BIDDING 

   SS/L generally obtains its contracts through competitive bidding. There 
can be no assurance that SS/L will continue to be successful in having its 
bids accepted or, if accepted, that awarded contracts will result in 
profitability for SS/L. SS/L has in the past submitted bids which would 
result in minimal or no profitability due to a high level of non-recurring 
engineering costs. Such contracts are generally bid with the expectation of 
more profitable follow-on contracts as to which there is generally no advance 
assurance. To the extent that actual costs exceed the projected costs on 
which bids or contract prices were based, SS/L's profitability could be 
adversely affected. 

REGULATION 

   The Loral Group's activities, particularly the Globalstar System, Skynet 
and Orion, are subject to licensing and regulation by authorities in more 
than 100 jurisdictions, including the United States, the International 
Telecommunications Union ("ITU") and the Commission of the European Union. 
Regulated activity includes the occupation of orbital positions ("orbital 
slots"), the pricing and quality of services, the use of frequency bands, 
competitive behavior, the export of space-related products and services 
(which frequently require licenses from the Department of State or the 
Department of Commerce), and other matters essential to conduct of the 
business. The regulatory authorities, depending on the location, often have 
broad discretion over such activities, including frequently the power to 
modify, withdraw or impose charges or conditions upon, or delay the grant of, 
the rights required for the conduct of the business. In particular, in 
determining whether to grant the Loral Group authorization, the FCC must 
evaluate whether certain FCC standards and financial qualification 
requirements are met. Many of the licenses the Loral Group holds or has 
applied for have been contested by third parties, including competitors, 
which increase the risk of regulatory decisions adverse to the Loral Group. 
In particular, two of Loral's Ka-band orbital slots for CyberStar are in 
positions that are subject to prior claims of parties from other countries. 
While regulation is an expected incident of international telecommunications 

                                       26

business, and the Loral Group expects to obtain the rights and licenses which 
it requires under satisfactory conditions, the broad reach of the Globalstar 
System, the expansion of Skynet's operations beyond the domestic U.S. market, 
the expansion of SatMex's Latin American presence, the proposed launch and 
operation of Orion 2 and Orion 3 and the development of other satellite 
services businesses, by becoming subject to such a large number of diverse 
regulatory regimes and political systems, entail unusual risks of unforeseen 
costs, delays and other burdens on planned performance. In addition, as part 
of the regulatory process for orbital slot allocation of its satellites, the 
Loral Group is required to engage in frequency coordination with other 
satellite operators. Although the Loral Group has in the past been able to 
coordinate its existing satellites, there can be no assurance that 
satisfactory coordination will be achieved in the future for any of the Loral 
Group's satellites. 

   Orion has begun construction of Orion 2 and Orion 3 before completion of 
the required consultation with Intelsat and Eutelsat, receipt of final 
authority from the FCC (in the case of Orion 2) and completion of the ITU 
coordination process. Failure to obtain one or more necessary approvals on 
time would have an adverse effect on Orion's business or results of 
operations. 

POTENTIAL CONFLICTS OF INTEREST; LACK OF FULL CONTROL 

   Loral has financed the development and acquisition of certain of its 
assets which it does not own completely through complex financial and 
governance arrangements. Loral currently owns directly and indirectly, on a 
fully diluted basis, approximately 39% of Globalstar and approximately 49% of 
SatMex. 

   Loral is the managing general partner of Globalstar, but its governance 
rights are limited by rights of other partners and fiduciary duties that 
could result in Globalstar actions that are not in Loral's own best 
interests. In accordance with Mexican law, voting control of SatMex must be 
held by Mexican nationals. While Loral's investment will be protected by 
contractual rights and it is anticipated that SatMex will be managed in close 
coordination with the activities of Skynet, there can be no assurance that 
SatMex will be managed as it would be if it were a controlled subsidiary of 
Loral. 

   Conflicts of interest may arise as a result of such arrangements, and 
because some of the Loral Group's businesses may (i) compete with one another 
and (ii) are or may become customers of SS/L. 

   Both Skynet and Orion own or are building satellites whose footprints 
overlap with those of SatMex's present and proposed satellites and will 
therefore compete directly with SatMex for customers in some of its markets. 
Although Skynet and Orion will adopt a marketing policy which will provide 
for cross-selling of capacity with SatMex and a process for allocating 
opportunities between the companies, situations may arise where SatMex and 
Loral will have a conflict. This conflict will become particularly acute if 
there is an oversupply of capacity in their markets. 

   Partners and affiliates of Globalstar, including companies affiliated with 
Loral, will be among Globalstar's service provider customers and may 
therefore have conflicts with Globalstar and/or Loral as to service provider 
agreements. 

RISKS OF CONDUCTING INTERNATIONAL BUSINESS 

   Operations in numerous countries outside the United States carry 
substantial managerial, operational, legal and political uncertainties apart 
from the technical risks of initiating a previously untried 
telecommunications system. Such operations are subject to changes in 
government regulations and telecommunications standards, tariffs or taxes and 
other trade barriers. In addition, the Loral Group's agreements relating to 
local operations may be enforceable only in foreign jurisdictions so that it 
may be difficult for the Loral Group to enforce its rights. Also, limited 
availability of U.S. currency in local markets may prevent a service provider 
from making payments in U.S. dollars and exchange rate fluctuations may 
adversely affect Globalstar's, SatMex's and Orion's revenues. Loral does not 
expect the Asian currency crisis to have any material impact on Loral's 
businesses. 

INTEGRATION OF THE BUSINESSES OF LORAL AND ORION 

   Loral and Orion have entered into the Merger Agreement with the 
expectation that the Merger will result in certain benefits. Achieving such 
benefits will depend in part upon the efficient integration of the 

                                       27
<PAGE>
businesses of Loral and Orion and will require substantial attention from 
management. The diversion of management attention and any difficulties 
encountered in the transition process could have an adverse effect on the 
Loral Group. In addition, the process of combining Loral and Orion could 
cause the interruption of, or a disruption in, the activities of either or 
both of the companies' businesses, which could have a material adverse effect 
on their combined operations. 

RELIANCE ON KEY PERSONNEL 

   The success of the Loral Group will be partially dependent upon the 
ability of the Loral Group to attract and retain highly qualified personnel. 
Except for Mr. Bernard L. Schwartz, Loral's Chairman and Chief Executive 
Officer, none of the officers of the Loral Group has an employment contract 
with the Loral Group nor does Loral expect to maintain "key man" life 
insurance. The loss of any of these individuals and the subsequent effect on 
business relationships could have an adverse effect on the business or 
results of operations of the Loral Group. 

DEPENDENCE ON SS/L 

   Currently, SS/L generates a significant portion of Loral's revenue and 
operating income. Loral intends to capitalize on SS/L's capabilities, market 
position and advanced technologies to identify and develop additional 
space-based communications services opportunities. There can be no assurance 
that current or future satellite-based ventures entered into by Loral will 
result in revenues or operating income that will materially reduce its 
dependence on SS/L. 

   SS/L has historically derived a large portion of its total revenues from a 
limited number of customers, and its revenues and operating results may be 
adversely affected in the event completed or canceled contracts are not 
promptly replaced. For the nine months ended December 31, 1996, sales to two 
customers represented 43% of SS/L's revenues. 

   The financial results of long-term fixed-price contracts are recognized 
using the cost-to-cost percentage of completion method. Loral's Statement of 
Operations reflects revisions in revenue and profit estimates in the period 
in which the conditions that require the revision become known and can be 
estimated. Adjustments for profits and losses may therefore have a material 
effect on results for the period in question. The risks inherent in 
long-term, fixed-price contracts include the forecasting of costs and 
schedules, contract revenues related to contract performance (including 
revenues from orbital payments) and the potential for component obsolescence 
in connection with long-term procurements. 

   In 1997, two in-orbit satellites built by SS/L have experienced some solar 
array circuit failures. One of the customers has asserted that, in light of 
the failures and uncertainty as to failure, it has not accepted the 
satellite. Loral believes that the customer was contractually required to 
accept the satellite at completion of in-orbit testing and that risk of loss 
has passed to the customer. In addition, due to a delay caused by the 
replacement on a satellite under construction of solar arrays similar to 
those that have experienced failures, another customer has requested that 
SS/L structure an arrangement whereby the satellite would be sold to another 
customer. Management believes that these matters will not have a material 
adverse effect on the business or results of operations of the Loral Group. 

   In January 1998, SS/L announced the elimination of up to 300 jobs, or 9% 
of its work force, as a result of its suspension of work on three satellites 
for two Asian programs. The satellites in question were being built for Asia 
Pacific Broadcasting and Communications Network PCL ("ABCN") of Bangkok, 
Thailand and P.T. Pasifik Satelit Nusantara of Jakarta, Indonesia. SS/L's 
backlog is approximately $1.8 billion after the de-booking of these projects. 
SS/L expects that if financial arrangements are not concluded in the near 
future that would permit these programs to be restarted, the satellites in 
question will be redeployed to other customers. 

OPERATING LOSSES 

   For the nine months ended September 30, 1997, Loral's net loss applicable 
to common stockholders was $29.2 million. The loss is primarily due to 
development costs related to new satellite-based services, allocated 
Globalstar losses, and preferred dividends.

   The holders of a majority of the votes of the shares of Orion Capital 
Stock issued and outstanding and entitled to vote, present in person or 
represented by proxy, treated as a single class, will be required to 
constitute a quorum at the Special Meeting. Under the Delaware General 
Corporation Law, as amended (the "DGCL"), abstentions and broker non-votes 
are counted for purposes of determining a quorum. 

VOTE REQUIRED 

   Under Orion's Amended and Restated By-laws and applicable law, the 
approval and adoption of the Merger Agreement requires the affirmative vote 
of the holders of a majority of the outstanding shares of Orion Common Stock 
and Orion Preferred Stock, entitled to vote at the Special Meeting, voting 
together as a single class, with each share of Orion Common Stock entitled to 
one vote per share, and each share of Orion Preferred Stock (including 
fractional shares) entitled to one vote for each whole share of Orion Common 
Stock that would be issuable upon conversion of such shares of Orion 
Preferred Stock, as described above under "Voting Rights and Related 
Matters". The approval of the amendments to the Director Option Plan and the 
Puente and Hauser Option Agreements require the affirmative vote of the 
holders of a majority of the shares of Orion Common Stock and Orion Preferred 
Stock present in person or represented by proxy and entitled to vote at the 
Special Meeting, voting together as a single class, with each share of Orion 
Common Stock entitled to one vote per share, and each share of Orion 
Preferred Stock (including fractional shares) entitled to one vote for each 
whole share of Orion Common Stock that would be issuable upon conversion of 
such shares of Orion Preferred Stock, as described above under "Voting Rights 
and Related Matters." Certain members of the Orion Board of Directors and 
their affiliated companies holding, in the aggregate, approximately 32% of 
the voting stock outstanding as of February 12, 1998, have agreed pursuant to 
the Principal Stockholder Agreement to vote for approval and adoption of the 
Merger Agreement. 

   Under the DGCL, abstentions, but not broker non-votes, are counted as 
shares entitled to vote for purposes of determining whether a proposal has 
been approved by the necessary number of votes. Abstentions on a proposal 
will have the effect of a vote against such a proposal. 

   On the Record Date, directors and executive officers of Orion, together 
with their affiliates as a group, beneficially owned an aggregate of 
7,020,140 shares of Orion Common Stock (assuming conversion of their shares

                           INFORMATION ABOUT ORION 

   Orion is a rapidly growing provider of satellite-based communications 
services, focused primarily on (i) private communications network services, 
(ii) Internet services and (iii) video distribution and other satellite 
transmission services. Orion provides multinational corporations with private 
communications networks designed to carry high speed data, fax, video 
teleconferencing, voice and other specialized services. The Orion satellite's 
ubiquitous coverage reaches all locations within its footprint, enabling the 
delivery of high speed data to customers in emerging markets and remote 
locations which lack the necessary infrastructure to support these services. 
Orion also offers high speed Internet access and transmission services to 
companies outside the United States seeking to avoid "last mile" terrestrial 
connections and to bypass congested regional Internet network routes. In 
addition, Orion provides satellite capacity for video distribution, satellite 
news gathering and other satellite services primarily to broadcasters, news 
organizations and telecommunications service providers. Orion provides its 
services directly to customer premises using VSATs. 

   Orion commenced operations of Orion 1, a high power Ku-band satellite with 
34 Ku-band transponders, in January 1995. As of September 30, 1997, Orion 
serviced 282 customers through 635 sites in service. As of September 30, 
1997, Orion's contract backlog was $254.1 million (including $89 million for 
one pre-launch customer on Orion 3). Orion presently anticipates that 
approximately $62 million of its $254.1 million in backlog (as of September 
30, 1997) will be realized in 1998. The weighted average realization of the 
backlog was approximately 22 months, and the entire backlog should be filled 
by 2008. Substantially all of Orion's current contracts with customers are 
denominated in U.S. dollars. For the nine months ended September 30, 1997, 
Orion generated revenues of $54.5 million and had a loss from operations, net 
loss, net cash used in operating activities and EBITDA (as defined below) of 
$30.5 million, $78.2 million, $17.8 million and $5.3 million, respectively. 
For the year ended December 31, 1996, Orion generated revenues of $41.8 
million and had a loss from operations, net loss, net cash used in operating 
activities and EBITDA of $36.4 million, $27.2 million, $21.8 million and $0.6 
million, respectively. "EBITDA" represents earnings before minority 
interests, interest income, interest expense, other expense (income), income 
taxes, depreciation and amortization. EBITDA is commonly used in the 
communications industry to analyze companies on the basis of operating 
performance, leverage and liquidity. EBITDA is not intended to represent cash 
flows from operating, investing or financing activities as determined in 
accordance with generally accepted accounting principles ("GAAP"). EBITDA is 
not a measurement under GAAP and may not be comparable to other similarly 
titled measures of other companies. 

   Orion believes that demand for satellite-based communications services 
will continue to grow due to (i) the expansion of businesses beyond the 
limits of wide bandwidth terrestrial infrastructure, (ii) accelerating demand 
for high speed data services, (iii) growing demand for Internet and intranet 
services, especially outside the United States, (iv) increased size and scope 
of television programming distribution, (v) worldwide deregulation of 
telecommunications markets and (vi) continuing technological 

                                       31
<PAGE>
advancements. Satellites are able to provide reliable, high bandwidth 
services anywhere in their coverage areas, and Orion believes that it is well 
positioned to satisfy market demand for these services. 

   Orion 1 provides coverage of 34 European countries, much of the United 
States and parts of Canada, Mexico and North Africa. Through arrangements 
with local ground operators, Orion currently has the ability to deliver 
network services to and among points in 27 European countries, portions of 
the United States and a limited number of Latin American countries. 

   In July 1996, Orion signed a contract with Matra Marconi Space UK Limited 
("Matra Marconi Space"), which was amended and restated in January 1997, for 
the construction and launch of Orion 2, its second satellite, and in February 
1997 commenced construction of that satellite. Orion 2, which will be a high 
power satellite with 30 Ku-band transponders, will expand Orion's European 
coverage and extend coverage to portions of the Commonwealth of Independent 
States, Latin America and the Middle East. Orion 2 will increase 
significantly Orion's pan-European capacity, currently the area of strongest 
demand for Orion's services. Orion recently commenced selling services in 
certain areas of Latin America. Orion 2 is scheduled to be launched in the 
second quarter of 1999. 

   In January 1997, Orion entered into a satellite procurement contract with 
Hughes Space and Communications International, Inc. for the construction and 
launch of Orion 3, construction of which was commenced in December 1996. 
Orion 3, which will be a high power satellite with 33 Ku-band transponders 
and 10 C-Band transponders, will cover broad areas of the Asia Pacific 
region, including China, Japan, Korea, India, Southeast Asia, Australia, New 
Zealand, Eastern Russia and Hawaii. Orion 3's footprint will provide Orion 
with the ability to distribute programming from the United States via Hawaii 
to most of the Asia Pacific region. Orion has already taken a number of steps 
to establish an early market presence in Asia, and has entered into a $89 
million lease for eight of Orion 3's transponders. Orion 3 is scheduled to be 
launched in the fourth quarter of 1998. 

   In the aggregate, the footprints of Orion 1, Orion 2 and Orion 3 will 
cover over 85% of the world's population. 

   Orion's principal executive offices are located at 2440 Research 
Boulevard, Rockville, Maryland 20850, and its telephone number is (301) 
258-8101. 

RECENT DEVELOPMENTS 

 Pre-Construction Lease on Orion 3 

   Orion has entered into a contract with DACOM Corp., a Korean 
communications company ("DACOM"), under which DACOM will, subject to certain 
conditions, lease eight dedicated transponders on Orion 3 for 13 years, in 
return for approximately $89 million, payable over a period from December 
1996 through seven months following the lease commencement date for the 
transponders (which is scheduled to occur by January 1999). Payments are 
subject to refund if Orion 3 fails to commence commercial operation by June 
30, 1999. 

 Acquisition of Teleport Europe GmbH 

   On March 26, 1997, Orion acquired Teleport Europe GmbH (whose name was 
subsequently changed to Orion Network Systems-Europe GmbH) ("Orion Europe"), 
a German communications company specializing in private satellite networks 
for voice and data services. Orion purchased the shares of Orion Europe held 
by two German companies, Vebacom GmbH and RWE Telliance AG, now known as 
o.tel.o., for $8.9 million. Orion Europe's 1996 revenues were approximately 
$14 million. The acquisition expanded Orion's customer base by approximately 
55 customers, including some of Germany's leading multinational corporations, 
and added over 200 network service sites (exclusive of broadcast service 
sites). In addition, Orion acquired Orion Europe's licenses and operating 
agreements to provide satellite network services in 40 countries, including 
17 countries in which Orion previously did not provide service. 

 January 1997 Transactions 

   In January 1997, Orion consummated a series of transactions that are 
described briefly below, including the Exchange, the January Merger, the Bond 
Offering and the Debentures Offering (each as 

                                       32
<PAGE>
defined below), the acquisition of the remaining minority interest in a 
subsidiary and certain uses of proceeds of the offerings (collectively, the 
"January 1997 Transactions"), all as described more fully in Note 9 to the 
Consolidated Financial Statements incorporated herein by reference from 
Orion's Annual Report on Form 10-K for the year ended December 31, 1996 and 
amendment thereto on Form 10-K/A dated June 25, 1997 (together, the "1996 
Form 10-K"). 

   The Exchange. On January 31, 1997, Orion acquired all of the limited 
partnership interests which it did not already own in Orion's operating 
subsidiary, International Private Satellite Partners, L.P. ("Orion 
Atlantic"), that owns the Orion 1 satellite. Specifically, pursuant to a 
Section 351 Exchange Agreement and Plan of Conversion (the "Exchange 
Agreement"), Orion acquired the Orion Atlantic limited partnership interests 
and other rights relating thereto held by British Aerospace Communications, 
Inc., COM DEV Satellite Communications Limited, Kingston, Communications 
International Limited, Lockheed Martin Commercial Launch Services, Inc., MCN 
Sat US, Inc., an affiliate of Matra Hachette, and Trans-Atlantic Satellite, 
Inc., an affiliate of Nissho Iwai Corp. (collectively, the "Exchanging 
Partners"). The Exchanging Partners exchanged (the "Exchange") their Orion 
Atlantic limited partnership interests for 123,172 shares of Orion Series C 
Preferred Stock. In addition, Orion acquired certain rights held by certain 
of the Exchanging Partners to receive repayment of various advances 
(aggregating approximately $41.6 million at January 31, 1997). The 123,172 
shares of Orion Series C Preferred Stock issued in the Exchange are 
convertible into approximately 7 million shares of Orion's Common Stock. As a 
result of the Exchange, certain of the Exchanging Partners became principal 
stockholders of Orion. 

   The January Merger.  Pursuant to the Exchange Agreement, Orion Oldco 
Services, Inc., formerly known as Orion Network Systems, Inc. ("Old Orion"), 
formed Orion as a new Delaware corporation with a certificate of 
incorporation, bylaws and capital structure substantially identical in all 
material respects with those of Old Orion. Also pursuant to the Exchange 
Agreement, Orion formed a wholly owned subsidiary, Orion Merger Company, Inc. 
("Orion Merger Subsidiary"). Pursuant to an Agreement and Plan of Merger, 
Orion Merger Subsidiary was merged with and into Old Orion, and Old Orion 
became a wholly owned subsidiary of Orion (the "January Merger"). On January 
31, 1997, the effective time of the January Merger, all of the stockholders 
of Old Orion received stock in Orion with substantially identical rights to 
the Old Orion stock they held prior to the effective time of the January 
Merger. Following the January Merger, Orion changed its name from Orion Newco 
Services, Inc. to Orion Network Systems, Inc. and Orion's wholly owned 
subsidiary, Orion Network Systems, Inc., changed its name to Orion Oldco 
Services, Inc. 

   Bond Offering and Debentures Offering. On January 31, 1997, Orion 
completed the $710 million Bond Offering composed of 445,000 Senior Note 
Units, each of which consists of one 11 1/4% Senior Note with a principal 
amount of $1,000 due 2007 and one Senior Note Warrant to purchase 0.8463 
shares of Orion Common Stock, and 484,000 Senior Discount Note Units, each of 
which consists of one 12 1/2% Senior Discount Note with a principal amount of 
$1,000 due 2007 and one Warrant to purchase 0.6628 shares of Orion Common 
Stock. Interest on the Senior Notes is payable semi-annually in cash on 
January 15 and July 15 of each year, commencing July 15, 1997. The Senior 
Discount Notes do not pay cash interest prior to January 15, 2002. 
Thereafter, cash interest will be payable semi-annually on January 15 and 
July 15 of each year, commencing July 15, 2002. 

   On January 31, 1997, Orion also completed the sale of $60 million of its 
convertible junior subordinated debentures (the "Debentures") to two 
investors, British Aerospace Holdings, Inc. ("British Aerospace" or "BAe") 
and Matra Marconi Space. British Aerospace purchased $50 million of the 
Debentures and Matra Marconi Space purchased $10 million of the Debentures 
(collectively, the "Debentures Offering"). 

   Orion used a portion of the net proceeds of the Bond Offering and 
Debentures Offering primarily to repay the Orion 1 credit facility and to 
pre-fund the first three years of interest payments on the Senior Notes. 
Orion plans to use the balance of such net proceeds primarily to build and 
launch Orion 2 and Orion 3.

LORAL SKYNET 

   Loral's Skynet division, acquired in March 1997 from AT&T, is a leading 
U.S. satellite communications service provider which owns and operates the 
Telstar satellite network. Loral Skynet leases transponder capacity to its 
customers for distribution of network television programs to local affiliate 
stations, collection of live video feeds for the reporting of news and 
sporting events and for distance learning and educational and other business 
television services. Loral Skynet currently has two high-powered satellites 
operating in-orbit: Telstar 4, with 24 C-band and 24 Ku-band transponders, 
and the 52-transponder Telstar 5, which was built by SS/L and launched in May 
1997. Loral Skynet plans to launch a number of additional high-powered 
C/Ku-band satellites. The addition of these satellites is intended to 
substantially increase Loral Skynet's capacity within the United States, and 
will extend its coverage area to Canada and Mexico. Telstar 6 is scheduled 
for launch in October 1998. 

GLOBALSTAR 

   Loral manages and currently owns, directly and indirectly, on a fully 
diluted basis, approximately 39% of Globalstar. Globalstar has begun to 
launch and is preparing to operate a worldwide, LEO satellite-based digital 
telecommunications system (the "Globalstar(Trademark) System") that is 
scheduled to commence service in early 1999. The Globalstar System is 
designed to enable local service providers to offer low-cost, high quality 
wireless voice telephony and data services in virtually every populated area 
of the world. To date, Globalstar's designated service providers have agreed 
to offer service and seek all necessary regulatory approvals in more than 100 
nations, accounting for about 88% of the world's population. 

   The Globalstar System's worldwide coverage is designed to enable its 
service providers to extend modern telecommunications services to millions 
who lack basic telephone service and to enhance wireless telecommunications 
in areas underserved by existing or future cellular systems, providing a 
telecommunications solution in parts of the world where the construction of 
terrestrial systems is not economically 

                                       34
<PAGE>
justified. The Globalstar System has been designed to provide service at 
prices comparable to today's cellular service and which are substantially 
lower than those announced by Globalstar's principal anticipated competitors. 
Loral, together with partners, will be Globalstar service providers in 
Canada, Brazil and Mexico. Jointly with QUALCOMM, Loral holds the exclusive 
rights to provide in-flight phone service using Globalstar in the United 
States. 

   As of February 14, 1998, each of the elements of the Globalstar System -- 
space and ground segments, digital communications technology, user terminal 
supply, service provider arrangements and licensing -is on schedule. 
Globalstar launched its four initial satellites on February 14, 1998 and 
expects to commence commercial operations in the first quarter of 1999 
following the launch of an additional 40 satellites during 1998. The 
remaining 12 satellites will be launched in early 1999 as scheduled. 

   Globalstar's current budgeted expenditures for the cost for the design, 
construction and development of the Globalstar System, including working 
capital, cash interest on anticipated borrowings and operating expenses, 
after giving effect to the rescheduled launch, are approximately $2.7 
billion. Globalstar has raised or received commitments for approximately $2.6 
billion in equity, debt and vendor financing. 

SPACE SYSTEMS/LORAL 

   Loral's wholly-owned subsidiary, SS/L, is a worldwide leader in the 
design, manufacture and integration of telecommunications, weather and direct 
broadcast satellites with over 35 years of experience. SS/L is the leading 
supplier of satellites to Intelsat, which is an international consortium of 
135 member nations and the world's largest operator of commercial 
communications satellites. Other significant SS/L customers include APT 
Satellite, Chinasat, Globalstar, MCI, PanAmSat, Loral Skynet and TCI. SS/L 
has a broad range of technical capabilities in spacecraft design, as well as 
all critical spacecraft subsystems, and maintains a completely integrated 
complex of satellite manufacturing, assembly, integration and testing 
facilities. The satellites built by SS/L have accumulated more than 600 years 
of service in space. This 600-year milestone represents the combined success 
of 88 communications and weather satellites built by SS/L since 1960. 

   SS/L has a history of technical innovation that includes the first 
three-axis stabilized satellites, bipropellant propulsion systems for 
commercial satellites that permit significant increases in the satellites' 
payload and extend the on-orbit lifetime, rechargeable nickel-hydrogen 
batteries with a life span of ten years or more, the use of advanced 
composites to significantly enhance satellite performance at lighter weights, 
and the first communications satellite with more than ten kilowatts of power. 
SS/L also created the first multi-mission geostationary satellite and was the 
first U.S. company to exchange space technology with Russia's space industry, 
obtaining exclusive rights outside the former Eastern bloc to an electric 
propulsion subsystem that is five times as efficient as bipropellant 
propulsion systems. Since 1993, SS/L has shortened delivery schedules 
significantly, increased spacecraft reliability by 30% and increased 
spacecraft power by 60%. When combined with recent improvements in 
transmission technology, the total communications capacity of an SS/L 
satellite has increased 20-fold since 1993. See "Risk Factors--Dependence on 
SS/L." 

LORAL ORION 

   For a description of Orion's business, see "--Information About Orion." 
Following consummation of the Merger, Loral intends to operate the business 
of Loral Orion in close coordination with the businesses of Loral Skynet and 
of SatMex so that each of its affiliates can benefit from one another's 
particular marketing strengths and areas of technical expertise, with a view 
to creating a coordinated, world-wide system, fully integrated with 
terrestrial telecommunications networks. 

SATMEX 

   In December 1997, a joint venture company in which Loral holds a 65% 
economic interest, completed the acquisition of a 75% interest in SatMex. 
SatMex is the dominant satellite telecommunications company currently 
providing services in Mexico. SatMex owns and operates three geosynchronous 
telecommunications satellites: Morelos II, Solidaridad 1 and Solidaridad 2. 
The total payload of the 

                                       35
<PAGE>
Mexican satellites is 4,752 MHz distributed in 72 transponders in C-Band (36 
MHz each) and 40 transponders in Ku-band (54 MHz each) for a total of 132 36 
MHz transponder equivalents. A replacement for the Morelos II, which is 
currently approaching the end of its life, is under construction by Hughes 
and is expected to be launched in the fourth quarter of 1998. SatMex intends 
to utilize the considerable expertise of its new equity owners, Loral and 
Telefonica Autrey, a company with extensive experience in the Mexican 
communications industry, to transform SatMex from a government agency into a 
commercially-oriented business focused on increasing revenues and 
profitability. 

FUTURE OPPORTUNITIES 

   Loral is pursuing additional satellite-based communications services 
opportunities, including CyberStar, a proposed worldwide high-speed broadband 
communications system using GEO satellites designed to provide interactive 
multimedia data transmission. Initially, services will be offered using 
leased Ku-band transponders. Loral will also deploy a Ka-band CyberStar 
constellation. Loral holds FCC licenses for the necessary CyberStar Ka-band 
orbital slots covering the Americas, Asia, Europe and the Middle East. In 
addition, Loral, through SS/L, recently established a joint venture with 
Mabuhay to provide direct-to-home ("DTH") services to the Philippines, and 
holds a 12.4% equity interest in CD Radio, Inc., a company that is proposing 
to establish a service to provide digital audio radio service to automobiles 
by satellite. 

   Loral's principal U.S. executive offices are located at 600 Third Avenue, 
New York, New York 10016 and its telephone number is (212) 697-1105.

                                  THE MERGER 
                                 (PROPOSAL 1) 

   The following discussion summarizes the principal aspects of the Merger, 
as set forth in the Merger Agreement and the exhibit thereto. The information 
in this Section is qualified in its entirety by reference to the full text of 
the Merger Agreement, including the exhibit thereto, a copy of which is 
attached hereto as Attachment A. 

           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 1. 

BACKGROUND OF THE MERGER 

   Orion's principal business is the provision of global satellite 
communications for private communications networks and transmission capacity 
and video distribution services. Orion's satellite system, as envisaged over 
the last several years, is to include at least three satellites, which would 
give Orion coverage of the large majority of the world's population. 

   From its inception in 1982 through January 20, 1995, Orion was a 
development stage enterprise. On January 20, 1995, Orion Atlantic's first 
satellite, Orion 1 (with coverage of Europe and most of the United States) 
commenced commercial operations. Since January 1995, Orion had been pursuing 
the refinancing of the senior debt incurred in connection with Orion 1 and 
the financing, construction and operation of two additional satellites, Orion 
2 (with coverage of Europe, the eastern United States and South America) and 
Orion 3 (with coverage of the Asia Pacific region). Orion completed an 
initial public offering in August 1995, raising approximately $50 million in 
net proceeds, but its plans for Orion 2 and Orion 3 required significantly 
greater amounts of capital. 

   In the fall of 1995, Orion Atlantic commenced but ultimately deferred a 
plan to raise over $290 million of financing for Orion 2, plus $300 million 
of senior secured notes to repay the existing Orion 1 Credit Facility, make 
certain repayments to the limited partners of Orion Atlantic and provide 
working capital (the "1995 Proposed Financing"). Following the deferral of 
the 1995 Proposed Financing, Orion continued to pursue financing for Orion 2 
and Orion 3, including, as a possible alternative, the sale of a substantial 
amount of equity to a new strategic partner. During this period Orion also 
pursued, as an important component of the financing of Orion 2 and Orion 3, 
and of a possible transaction with a strategic partner, the exchange by the 
non-Orion limited partners of Orion Atlantic of their partnership interests 
in Orion Atlantic for stock in Orion. 

   In November 1996, Orion engaged Morgan Stanley & Co., Incorporated 
("Morgan Stanley") as its investment banker, and filed proxy materials for a 
merger and exchange transaction that would effect the conversion of the 
limited partners' partnership interests in Orion Atlantic for stock in Orion, 
and commenced work on a registration statement (filed in December 1996) for a 
high yield offering to repay the Orion 1 Credit Facility and finance Orion 2 
and Orion 3. During December 1996, Orion received an indication of interest 
from Loral regarding a possible strategic transaction or acquisition, but 
elected to defer consideration of such a transaction to complete the high 
yield financing and the limited partner exchange. The high yield financing 
and limited partner exchange, and other January 1997 Transactions, were 
consummated on January 31, 1997. 

   At a meeting of the Orion Board of Directors held on February 12, 1997, 
the Board considered a number of strategic matters, particularly ones 
relating to the failure of the market price of Orion Common Stock to increase 
in response to consummation of the January 1997 Transactions. Although the 
January 1997 Transactions were viewed as highly successful by the Orion Board 
of Directors and its advisors, they had not achieved the expected increase in 
stockholder value. Several possible reasons for the lack of appreciation were 
suggested, including the limited public float of the Orion stock, a downward 
shift in market prices for companies in Orion's industry generally, and 
perceived downward pressure on the Orion stock generated by the large number 
of shares issued to the former limited partners combined with an expectation 
that such former limited partners would sell such shares when eligible to do 
so. 

                                       37
<PAGE>
   On February 12, 1997, the Orion Board of Directors and Morgan Stanley 
discussed Orion's early stage of development and its operation of only one 
satellite. Although Orion had raised financing for two other satellites, it 
would be one to two years before such satellites would be ready for launch 
and operation. In addition, although the January 1997 Transactions 
constituted an important step in Orion's plan to build its business, the 
Orion Board of Directors believed that Orion's lack of financial resources 
for purposes other than construction of two additional satellites, and the 
perceived limitations on expanding through acquisitions due to the market 
price of Orion Common Stock, were limiting Orion's growth potential. 

   Also at the February 12, 1997 meeting, the Orion Board of Directors 
considered Orion's ability to conduct another public offering to relieve the 
limited public float problem and reduce the price pressure arising from the 
limited partner shares. The Orion Board of Directors discussed Orion's 
ability to pursue a transaction with a strategic investor or acquiror. The 
Orion Board of Directors determined to explore on a preliminary basis, in 
parallel, several possible paths, including a second public offering that 
would include shares held by the former limited partners, a strategy under 
which Orion would attempt to grow by acquiring other similar or complementary 
businesses despite its low stock price and limited financial resources, and a 
strategic transaction or sale of the company. 

   On March 26, 1997 and April 1, 1997, at Executive Committee and Orion 
Board of Directors meetings, respectively, Orion concluded that reductions in 
the market price for Orion stock had made a new public offering an 
unattractive alternative for the company (and the limited partners who may 
have wished to sell Orion stock) at that time. 

   On April 22, 1997, the Orion Board of Directors met and determined to 
explore the possible interest of a strategic partner in investing in or 
acquiring Orion. The Executive Committee of the Orion Board of Directors 
(consisting of John G. Puente (chairman), Gustave M. Hauser (chairman of the 
Orion Board of Directors), Sidney S. Kahn, W. Anthony Rice, John V. Saeman 
and Robert Van Degna), was formally given responsibility to oversee an 
orderly process of exploring possible transactions, subject to approval by 
the Orion Board of Directors of the terms of any such transaction. Morgan 
Stanley was asked to develop a list of companies that could be expected to 
have some interest in such a strategic partner investment or acquisition. At 
these and at other meetings, the Executive Committee and the Orion Board of 
Directors also reviewed Orion's prospects to expand through acquisitions. 

   During May 1997, the Executive Committee or its representatives met or 
spoke several times with representatives of Morgan Stanley to develop and 
refine a list of companies to approach, and initial contacts were made with 
certain companies, including Loral, to solicit interest in a transaction 
involving Orion. The list was subsequently expanded on several occasions, and 
additional companies were contacted. Following the initial contacts, weekly 
or bi-weekly meetings of the Orion Executive Committee (on May 28, June 4, 
June 12, June 18, June 25, July 2, July 9, July 16, July 25, August 4, August 
12, August 18, August 20, August 21, September 2, September 8, September 11, 
September 18 and October 1) were held until the Merger Agreement was 
executed, in each case with Morgan Stanley and counsel participating, to 
review and discuss the status of the exploration process, discuss issues 
raised by companies that had been contacted, discuss information regarding 
the potential strategic investors or acquirors and consider matters relating 
to Orion's business, plans and growth potential. 

   During May and early June, confidentiality agreements with various parties 
were executed and information requests were made of and responded to by 
Orion. Loral signed a confidentiality agreement with Orion on June 5, 1997 
and commenced its information requests immediately. 

   On May 22, 1997, the Orion Board of Directors instructed Morgan Stanley to 
forward to the various interested parties a letter outlining the procedures 
for written preliminary indications of interest. Loral was sent a similar 
letter on June 5, 1997. Over the next several weeks, the interested parties 
responded with preliminary indications of interest to Morgan Stanley. Most of 
such indications of interest were for an acquisition of Orion, although one 
proposal contemplated a substantial investment in Orion and various 
contractual relationships. On or about June 6, 1997, Loral submitted to 
Morgan Stanley its initial non-binding indication of interest in acquiring 
Orion in the form of an exchange for stock of Loral at a purchase price that 
would represent a small premium over market. 

                                       38
<PAGE>
   Pursuant to instructions of the Orion Board of Directors, Morgan Stanley 
notified certain of the interested parties of their selection to proceed to 
the due diligence phase of the process the following week. Loral was 
initially not invited into the next phase of the process, but was instructed 
that if Loral were to subsequently revise its proposal, it would receive 
access to additional information. A number of the interested parties and 
their representatives met at the offices of Hogan & Hartson L.L.P., counsel 
to Orion, in Washington, D.C. during June, July and August to attend 
management presentations, if requested, to review certain documents of Orion 
made available in a due diligence room, and to discuss with Orion and its 
representatives follow-up questions with respect to the management 
presentations and the due diligence materials. 

   On or about July 15, 1997, Orion received a non-binding proposal from 
Loral, proposing a purchase of Orion for cash at the then market price, with 
each Orion stockholder to receive a contingent value right that would give 
the stockholder shares of Loral stock equal to the difference between such 
market price and $17.00 if Orion achieved a specified revenue target during 
1998. This proposal was considered at a meeting of the Orion Executive 
Committee on July 16, 1997, at which most Orion directors were present. After 
debate by the Orion Executive Committee about the proposal and discussions 
with Morgan Stanley regarding the value to Orion stockholders of such a 
contingent value right, the proposal was rejected. Orion determined, however, 
that, based on the receipt of such proposal, Loral had shown sufficiently 
promising interest to include Loral in the next phase of the process. 
Thereafter, as discussed below, discussions between Orion and Loral continued 
during July, August and September regarding price and terms, possible 
transaction structures, legal issues and document review. During this period, 
Orion continued its discussions, directly or through Morgan Stanley, with 
other companies that remained interested in pursuing a transaction with 
Orion. 

   During the week beginning July 14, 1997, at the direction of the Board of 
Directors of Orion, Morgan Stanley discussed with various interested parties 
the preliminary indications of interest, the sale process and the related 
timetable, and on July 21, 1997, Morgan Stanley sent out a letter to 
interested parties, including Loral, outlining the procedures for a firm 
written offer for Orion and a draft merger agreement. The letter indicated 
that final proposals were due on August 11, 1997. 

   On July 24, 1997, representatives from Loral and Loral Skynet visited the 
offices of Hogan & Hartson L.L.P., counsel to Orion, and reviewed certain 
documents of Orion made available in a due diligence room and held due 
diligence discussions with Orion management. 

   On August 12, 1997, Loral management presented to the Loral Board of 
Directors, at its regularly scheduled meeting, information regarding the 
possible acquisition of Orion. After discussion, the Loral Board of Directors 
authorized Loral management to proceed with discussions and negotiations with 
Orion concerning a possible transaction and delegated to the Executive 
Committee of the Board of Directors the authority to approve a final 
agreement. Thereafter, during the remainder of the month of August, Loral 
submitted to and discussed with Morgan Stanley and Orion senior management 
various proposals regarding possible transaction structures in which Loral 
would acquire control of Orion. 

   In August 1997, rumors developed that GE American Communications, Inc. 
would acquire Orion, beginning with stories in the press on August 15, 1997 
and August 18, 1997. No new potential acquirors or strategic partners 
surfaced as a result of the rumored sale. 

   On August 29, 1997, Orion management visited the offices of Loral and 
conducted a management presentation for Loral executives. After further 
discussions between Loral and Orion and its representatives, on or about 
September 2, 1997, Loral proposed an acquisition of Orion for Loral Common 
Stock valued at $17.00 per share with a transaction structure similar to that 
ultimately set forth in the Merger Agreement. The proposal was oral, and was 
subject to various contingencies. Following a meeting of the Orion Executive 
Committee, Orion initially responded by requesting that Loral make an offer 
at a higher price or offer cash rather than Loral stock. Loral declined to 
increase its price and indicated that it would consider making a cash offer, 
but only subject to financing contingencies. While discussions between Orion 
and Loral continued, Orion's Executive Committee continued to consider 
whether the $17.00 proposal would represent an acceptable price for Orion 
stock. 

                                       39
<PAGE>
   On September 11, 1997, following additional Orion Executive Committee 
meetings, Orion approached Loral and indicated that certain large 
stockholders of Orion (mostly holding Orion Series C Preferred Stock) likely 
would not support a transaction at less than $17.50 per share, the conversion 
price of the Orion Series C Preferred Stock. After consideration, Loral 
orally indicated its nonbinding intention to negotiate a definitive merger 
agreement with Orion at $17.50 per share, provided that Orion's principal 
stockholders were prepared to agree to support this transaction. After 
further discussion by the Orion Executive Committee, Orion indicated to Loral 
its willingness to begin to negotiate a definitive merger agreement on the 
basis of the $17.50 Loral proposal. 

   Orion and Loral then commenced a period of intensive negotiations 
regarding the terms of a definitive merger agreement and principal 
stockholder agreement. In addition, on September 15, 1997, at Loral's 
offices, Loral management conducted a management presentation for Orion 
executives. During the negotiation period, until execution of the Merger 
Agreement, the Orion Executive Committee continued to meet on a weekly or 
semi-weekly basis to consider the issues that had been raised during the 
negotiations. 

   On September 24, 1997, the Orion Board of Directors met and received 
presentations from management, Morgan Stanley and legal advisors regarding 
the proposed Loral transaction. Following discussion, the Orion Board of 
Directors authorized management and its advisors to proceed with negotiating 
a definitive merger agreement with Loral, subject to Orion Board of Directors 
approval of the final terms and conditions. 

   On October 6, 1997, the Orion Board of Directors met again, and received 
detailed presentations from management, counsel and Morgan Stanley regarding 
the financial and legal aspects of the Loral transaction, the terms of the 
proposed Merger Agreement, Principal Stockholder Agreement and related 
transaction documents, an in-depth analysis of Loral, and alternatives to the 
Loral transaction. Morgan Stanley delivered an oral opinion to the Orion 
Board of Directors, which was confirmed by delivery of a written opinion 
dated October 6, 1997, to the effect that, based upon the analysis performed 
by Morgan Stanley and subject to the matters stated therein, the Exchange 
Ratio was fair from a financial point of view to the holders of Orion Common 
Stock (other than Loral and its affiliates) and, assuming conversion of Orion 
Preferred Stock into Orion Common Stock in accordance with their terms, to 
the holders of Orion Preferred Stock. See "--Opinion of Orion's Financial 
Advisor." After discussion and consideration, the Orion Board of Directors 
unanimously determined that the Merger Agreement and the transactions 
contemplated thereunder, including the Merger, are fair to, and in the best 
interests of, Orion and its stockholders, unanimously approved the Merger 
Agreement and the transactions contemplated thereunder, including the Merger, 
and unanimously recommended that the Merger be submitted to the stockholders 
of Orion for approval. 

   On October 6, 1997, the Executive Committee of the Loral Board of 
Directors met to evaluate the proposed transaction with Orion. After 
discussion and consideration, the Executive Committee, pursuant to authority 
delegated to it by the Board of Directors, unanimously approved the Merger 
Agreement and the transactions contemplated thereunder, including the Merger 
and the Principal Stockholder Agreement. 

   As of October 7, 1997, Orion and Loral executed the Merger Agreement and 
the Principal Stockholder Agreement, and the principal stockholders of Orion 
who are parties to the Principal Stockholder Agreement executed that 
agreement (which was amended and restated as of December 1, 1997 to make 
certain technical amendments). 

RECOMMENDATION OF ORION BOARD OF DIRECTORS; ORION'S REASONS FOR THE 
TRANSACTIONS 

   The Orion Board of Directors has approved the terms of the Merger 
Agreement and determined that the Merger Agreement and the transactions 
contemplated thereunder, including the Merger, are fair to, and in the best 
interests of, Orion and its stockholders. The Orion Board of Directors 
unanimously recommends that Orion stockholders vote "FOR" approval and 
adoption of the Merger Agreement and the transactions contemplated 
thereunder, including the Merger.

   In reaching its determination that the Merger Agreement and the 
transactions contemplated thereunder, including the Merger, are fair to, and 
in the best interests of, Orion and its stockholders, the Orion Board of 
Directors considered a number of factors, including the following: 

     (i) the Orion Board of Directors' desire to maximize stockholder value; 

     (ii) the failure of the market price of Orion Common Stock to increase 
    following the January 1997 Transactions; the limited public float of the 
    Orion Common Stock; a downward shift in market prices for companies in 
    Orion's industry generally; perceived downward pressure on the Orion stock 
    generated by the large number of shares issued to the former limited 
    partners combined with an expectation that such former limited partners 
    would sell such shares when eligible to do so; the less favorable 
    treatment of Orion by the market relative to other satellite companies 
    (particularly PanAmSat, a significant competitor of Orion, which was 
    viewed as having achieved significant value for its stockholders through 
    its acquisition by Hughes); and views of the Orion Board of Directors 
    about Orion's ability to conduct another public offering to relieve the 
    limited public float and reduce the price pressure arising from the 
    expectation of sales of the limited partner shares; 

     (iii) Orion's desire to build its business, perceived limitations on its 
    growth potential due to Orion's lack of financial resources for purposes 
    other than construction of two additional satellites, and the perceived 
    limitations on expanding through acquisitions due to the market price of 
    Orion Common Stock; 

     (iv) the current and prospective business environment in which Orion 
    operates, including the competitive environment for telecommunications 
    companies generally and satellite service providers specifically, the 
    trend toward consolidation in the satellite services industry; and the 
    Orion Board of Director's belief that although Orion had raised financing 
    for Orion 2 and Orion 3, it would be one to two years before such 
    satellites would be ready for launch and operation; 

     (v) Orion's belief that the Merger will increase its abilities to expand 
    its business opportunities and pursue its goal of becoming a preeminent 
    provider of satellite communications services; Orion's belief that its 
    international satellite business, including the Orion 2 and Orion 3 
    satellites under construction, will fit well with Loral's existing Skynet 
    business; Orion's belief that the Merger will enable Loral and Orion 
    collectively to offer global satellite services and take advantage of more 
    opportunities to expand satellite communications offerings than Orion is 
    able to pursue on its own; and Orion's expectation that as a subsidiary of 
    Loral, it will have increased access to the capital markets to provide 
    financing for such opportunities; 

     (vi) Orion's belief that in comparison to other potential transactions 
    and strategies that were available, or were reasonably expected to become 
    available over time, primarily proposed acquisitions of Orion or 
    investments in Orion at lower per share values or remaining independent 
    for the present and considering business combinations again in the future, 
    the Merger represented the best opportunity for increasing stockholder 
    value; 

     (vii) written and oral presentations by Morgan Stanley and the opinion of 
    Morgan Stanley that the Exchange Ratio is fair from a financial point of 
    view to the holders of Orion Common Stock (other than Loral and its 
    affiliates) and, assuming conversion of Orion Preferred Stock into Orion 
    Common Stock in accordance with their terms, to the holders of Orion 
    Preferred Stock; 

     (viii) the process followed by Morgan Stanley in seeking an acquiror for 
    Orion and the fact that the per share value based on the Exchange Ratio 
    was considerably above the market price for shares of Orion Common Stock 
    preceding the commencement of the process of exploring for a strategic 
    investor or acquiror, and that the market price for shares of Orion Common 
    Stock included significant appreciation based on speculation that Orion 
    was likely to be acquired; 

     (ix) the benefit to Orion stockholders from becoming stockholders in a 
    larger, more diversified entity with a substantially greater number of 
    outstanding shares and trading volume; 

     (x) oral presentations by executive officers of Orion regarding the 
    business, financial condition and recent results of operations of Orion, 
    and their best estimates of the prospects of Orion; 

                                       41
<PAGE>
     (xi) the fact that the terms of the Merger Agreement were determined 
    through arm's length negotiations; 

     (xii) the effect of the Merger on Orion's employees; 

     (xiii) the terms of the Merger Agreement and the Principal Stockholder 
    Agreement, as reviewed by the Orion Board of Directors with its legal and 
    financial advisors; and 

     (xiv) the Orion Board of Directors' belief, after consultation with its 
    legal counsel, that the required regulatory approvals could be obtained 
    for the Merger. 

   In view of the variety of factors considered in connection with its 
evaluation of the Merger, the Orion Board of Directors did not quantify or 
otherwise attempt to assign relative numerical weights to the specific 
factors that it considered in reaching its determination that the Merger is 
fair to, and in the best interests of, stockholders of Orion. 

OPINION OF ORION'S FINANCIAL ADVISOR 

   In 1997, Orion retained Morgan Stanley to act as its financial advisor in 
connection with a proposed sale or business combination involving Orion. 

   At the October 6, 1997 meeting of the Orion Board, Morgan Stanley rendered 
its oral opinion that, as of such date and subject to the various 
considerations to be set forth in its written opinion, the Exchange Ratio is 
fair from a financial point of view to the holders of Orion Common Stock 
(other than Loral and its affiliates) and, assuming the conversion of the 
Orion Preferred Stock into Orion Common Stock in accordance with their terms, 
to the holders of Orion Preferred Stock. Morgan Stanley subsequently 
delivered to the Orion Board a written opinion dated October 6, 1997 (the 
"Morgan Stanley Opinion") confirming such oral opinion. 

   THE FULL TEXT OF THE MORGAN STANLEY OPINION WHICH SETS FORTH, AMONG OTHER 
THINGS, ASSUMPTIONS MADE, PROCEDURE FOLLOWED, MATTERS CONSIDERED AND 
LIMITATIONS ON THE REVIEW UNDERTAKEN BY MORGAN STANLEY, IS ATTACHED AS 
ATTACHMENT C TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY 
REFERENCE. THE MORGAN STANLEY OPINION IS DIRECTED TO THE ORION BOARD AND 
ADDRESSES ONLY THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE EXCHANGE 
RATIO TO THE HOLDERS OF ORION COMMON STOCK AND, ASSUMING THE CONVERSION OF 
THE ORION PREFERRED STOCK INTO ORION COMMON STOCK IN ACCORDANCE WITH THEIR 
TERMS, THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE EXCHANGE RATIO TO 
THE HOLDERS OF ORION PREFERRED STOCK. IT DOES NOT ADDRESS ANY OTHER ASPECT OF 
THE MERGER AND DOES NOT CONSTITUTE AN OPINION OR A RECOMMENDATION AS TO HOW 
ANY HOLDER OF ORION COMMON STOCK OR ORION PREFERRED STOCK SHOULD VOTE AT THE 
SPECIAL MEETING OR WHETHER HOLDERS OF ORION PREFERRED STOCK SHOULD CONVERT 
THEIR SHARES OF ORION PREFERRED STOCK INTO ORION COMMON STOCK. IN ADDITION, 
THE MORGAN STANLEY OPINION DOES NOT IN ANY MANNER ADDRESS THE PRICES AT WHICH 
THE SHARES OF LORAL COMMON STOCK WILL TRADE FOLLOWING CONSUMMATION OF THE 
MERGER. THE SUMMARY OF THE MORGAN STANLEY OPINION SET FORTH IN THIS PROXY 
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL 
TEXT OF SUCH OPINION. THE HOLDERS OF SHARES OF ORION COMMON STOCK AND ORION 
PREFERRED STOCK ARE URGED TO READ THE MORGAN STANLEY OPINION IN ITS ENTIRETY. 

   In arriving at its opinion, Morgan Stanley, among other things:  (i) 
reviewed certain publicly available financial statements and other 
information of Orion, Loral and Globalstar; (ii) reviewed certain internal 
financial statements and other financial and operating data concerning Orion, 
Loral and Globalstar prepared by the respective managements of Orion, Loral 
and Globalstar and discussed certain of the foregoing with senior executives 
of Orion, Loral and Globalstar; (iii) analyzed certain financial forecasts of 
Orion, Loral and Globalstar prepared by the respective managements of Orion, 
Loral and Globalstar; (iv) discussed the past and current operations and 
financial condition and the prospects of Orion, Loral and Globalstar with 
senior executives of Orion, Loral and Globalstar; (v) reviewed the reported 
prices and trading activity for the common stock of Orion, Loral and 
Globalstar; (vi) compared the financial performance of Orion, Loral and 
Globalstar and the prices and trading activity of the Orion Common Stock and 
the common stock of Loral and Globalstar with that of comparable publicly 
traded companies and their securities; (vii) reviewed the financial terms, to 
the extent publicly available, of certain comparable acquisition 
transactions; (viii) participated in discussions and negotiations among 

                                       42
<PAGE>
representatives of Orion, Loral and certain other parties and their financial 
and legal advisors; (ix) reviewed the Merger Agreement, the Principal 
Stockholder Agreement and certain related documents; and (x) performed such 
other analyses and considered such other factors as Morgan Stanley deemed 
appropriate. 

   In rendering its opinion, Morgan Stanley assumed and relied upon, without 
independent verification, the accuracy and completeness of the information 
reviewed by Morgan Stanley for purposes of its opinion. Morgan Stanley 
assumed that the financial forecasts of Orion, Loral and Globalstar were 
reasonably prepared on bases reflecting the best currently available 
estimates and judgments of the future financial performance of Orion, Loral 
and Globalstar. Morgan Stanley did not make any independent valuation or 
appraisal of the assets or liabilities of Orion, Loral or Globalstar, nor was 
it furnished with any such appraisals. Morgan Stanley relied upon, without 
independent verification, the assessment by the respective managements of 
Orion, Loral and Globalstar of each of their technologies and products, the 
timing and risks associated with the integration of Orion and Loral, and the 
validity of, and risks associated with, Orion's, Loral's and Globalstar's 
existing and future products and technologies. The Morgan Stanley Opinion is 
necessarily based on economic, market and other conditions as in effect on, 
and the information made available to it as of, the date of the Morgan 
Stanley Opinion. Morgan Stanley assumed that in connection with the receipt 
of all necessary regulatory approvals for the Merger, no restrictions will be 
imposed that would have a material adverse effect on the contemplated 
benefits expected to be derived in the proposed Merger. 

   The following is a brief summary of certain analyses performed by Morgan 
Stanley and reviewed with the Orion Board in connection with its opinion to 
the Orion Board. 

   Historical Stock Performance.  Morgan Stanley's analysis of the 
performance of the Orion Common Stock consisted of a historical analysis of 
closing prices and trading volumes for the period from August 1, 1995 through 
and including October 3, 1997. During this period, Orion Common Stock 
achieved a high of $16.969 and a low of $8.00 per share. During the period 
from October 3, 1996 to August 15, 1997, the day upon which rumors of a 
possible GE American Communications bid for Orion reached the market, Orion 
achieved a high of $15.00 and a low of $8.00 per share. Orion Common Stock 
closed at a price of $16.969 per share on October 3, 1997. 

   Morgan Stanley also reviewed the performance of the Loral Common Stock, 
which consisted of a historical analysis of closing prices and trading 
volumes from the date of Loral's spin-off from Loral Corporation on April 16, 
1996 through and including October 3, 1997. During this period, Loral Common 
Stock achieved a high of $22.563 and a low of $12.00, based on closing per 
share prices. Loral Common Stock closed at a price of $22.00 per share on 
October 3, 1997. 

   Morgan Stanley also reviewed the performance of the common stock of 
Globalstar, which consisted of a historical analysis of closing prices and 
trading volumes from the date of Globalstar's IPO on February 14, 1995 
through and including October 3, 1997. During this period, the common stock 
of Globalstar achieved a high of $54.25 and a low of $5.875, based on closing 
per share prices. The common stock of Globalstar closed at a price of $54.25 
per share on October 3, 1997. 

   Comparable Company Analysis. Morgan Stanley performed a comparable public 
company analysis pursuant to which it compared certain financial information 
of Orion with that of a group of publicly traded satellite service operators, 
including APT Satellite Holdings Ltd., AsiaSat Telecommunications Holdings 
Ltd., PanAmSat/Hughes Galaxy and Pasifik Satelit Nusantara (collectively, the 
"Satellite Comparables"). The Satellite Comparables were selected based on 
the general business, operating and financial characteristics representative 
of companies in the satellite services industry. For fiscal years 1997 
through 2000, Morgan Stanley used financial forecasts prepared by Orion's 
management for the 1997 planning period (the "1997 Estimates"), which were 
the most recent forecasts prepared by Orion's management. In addition, Morgan 
Stanley conducted a sensitivity analysis using research consensus estimates 
for such fiscal years (the "Consensus Estimates"). Such financial information 
included. among other things, the ratio of common equity market value as 
adjusted for total debt ("Aggregate Value") to (i) EBITDA and (ii) 
shareholder's equity book value as adjusted for total debt and intangible 
assets ("Invested Book Capital"). Morgan Stanley noted that, the multiple of 
Aggregate Value to estimated 1999 

                                       43
<PAGE>
EBITDA was 7.1x for the 1997 Estimates and 13.8x for the Consensus Estimates, 
compared to a range of 7.6x to 10.3x, with a mean of 9.3x, for the Satellite 
Comparables; the multiple of Aggregate Value to estimated 2000 EBITDA was 
5.3x for the 1997 Estimates and 8.7x for the Consensus Estimates, compared to 
a range of 5.2x to 8.0x, with a mean of 6.6x, for the Satellite Comparables; 
and the multiple of Aggregate Value to Invested Book Capital was 1.2x for 
Orion, compared to a range of 2.4x to 5.1x, with a mean of 3.6x, for the 
Satellite Comparables. 

   No company utilized as a comparison in the comparable company analysis is 
identical to Orion. Accordingly, an analysis of the foregoing necessarily 
involves complex considerations and judgments concerning differences in 
financial and operating characteristics of Orion and the Satellite 
Comparables and other factors that could affect public trading 
characteristics of the Satellite Comparables. Mathematical analysis (such as 
determining the average or the mean) is thus not in itself the sole method of 
using the comparable company analysis. 

   Comparable Transaction Analysis. Using publicly available information, 
Morgan Stanley reviewed the PanAmSat and Hughes Galaxy transaction, which was 
the only transaction that Morgan Stanley considered comparable to the Merger. 
Morgan Stanley noted that in such transaction, using forecasts developed by 
securities analysts, Hughes Electronics effectively paid 9.9x 2-year forward 
EBITDA, 7.5x 3-year forward EBITDA and 6.7x 4-year forward EBITDA for 
PanAmSat on an Aggregate Value basis. Applying these multiples to 2-year, 
3-year, and 4-year forward EBITDA estimates from the 1997 Estimates and the 
Consensus Estimates, Morgan Stanley computed per share values for Orion 
ranging from $12.00 to $24.00. Morgan Stanley also noted that Hughes 
Electronics effectively paid a multiple of 2.4x PanAmSat's estimated June 30, 
1997 invested book capital as compared to 1.4x for the Merger. Morgan Stanley 
noted that the PanAmSat and Hughes Galaxy transaction is not identical to the 
Merger and that any comparison of such transactions necessarily involves 
complex considerations and judgments concerning differences in financial and 
operating characteristics of Orion and PanAmSat that could affect the 
acquisition value of Orion as compared to PanAmSat. 

   Discounted Cash Flow Analysis.  Morgan Stanley performed a discounted cash 
flow analysis of Orion for the fiscal years ended 1998 through 2006 based on 
the 1997 Estimates. Unlevered free cash flows were calculated as net income 
available to common stockholders plus preferred stock dividends plus 
depreciation and amortization plus deferred taxes plus other noncash expenses 
plus after-tax net interest expense less capital expenditures less investment 
in working capital. Morgan Stanley calculated terminal values by applying a 
range of EBITDA multiples in fiscal 2006 from 7.0x to 9.0x. The cash-flow 
streams and terminal values were then discounted to the present using a range 
of discount rates from 17.5% to 22.5%, representing an estimated weighted 
average cost of capital range of Orion. Based on this analysis, Morgan 
Stanley calculated per share values for Orion ranging from $16.25 to $35.17. 
Morgan Stanley also derived an implied per share equity value for Orion based 
on applying certain sensitivities to the forecasts provided by Orion's 
management, which indicated an implied per share equity value ranging from 
$6.21 to $32.65. 

   Loral Valuation. Morgan Stanley analyzed the valuation of Loral by 
applying discounted cash flow and trading analyses to the Space Systems/Loral 
and Skynet businesses of Loral, a discounted cash flow analysis to the 
CyberStar business of Loral and current market value and discounted cash flow 
analyses to the Globalstar investment of Loral. Morgan Stanley based the 
discounted cash flow analyses on Loral management's forecasts and applied 
applicable terminal EBITDA multiples and discount rate for each business, 
taken separately. Utilizing these analyses, Morgan Stanley calculated per 
share values for Loral ranging from $18.29 to $22.42. 

   The preparation of a fairness opinion is a complex process and is not 
necessarily susceptible to a partial analysis or summary description. In 
arriving at its opinion, Morgan Stanley considered the results of all of its 
analyses as a whole and did not attribute any particular weight to any 
particular analysis or factor considered by it. Furthermore, selecting any 
portions of Morgan Stanley's analyses, without considering all analyses, 
would create an incomplete view of the process underlying the Morgan Stanley 
Opinion. In addition, Morgan Stanley may have deemed various assumptions more 
or less probable than other assumptions, so that the ranges of valuations 
resulting for any particular analysis described above should not be taken to 
be Morgan Stanley's view of the actual value of Orion, Loral or Globalstar. 

                                       44
<PAGE>
   In performing its analyses, Morgan Stanley made numerous assumptions with 
respect to industry performance, general business and economic conditions and 
other matters, many of which are beyond the control of Orion, Loral or 
Globalstar. The analyses performed by Morgan Stanley are not necessarily 
indicative of actual values, which may be significantly more or less 
favorable than suggested by such analyses. Such analyses were prepared solely 
as a part of the Morgan Stanley Opinion and were provided to the Orion Board 
in connection with the delivery of the Morgan Stanley Opinion. The analyses 
do not purport to be appraisals or to reflect the prices at which Orion, 
Loral or Globalstar might actually be sold. Because such estimates are 
inherently subject to uncertainty, none of Orion, Loral, Globalstar or Morgan 
Stanley nor any other person assumes responsibility for their accuracy. In 
addition, as described above, the Morgan Stanley Opinion, including Morgan 
Stanley's presentation to the Orion Board, was one of many factors taken into 
consideration by the Orion Board in making its determination to approve the 
Merger. Consequently, Morgan Stanley's analyses described above should not be 
viewed as determinative of the opinion of the Orion Board with respect to the 
value of Orion, Loral or Globalstar. 

   The Orion Board retained Morgan Stanley based upon its experience and 
expertise. Morgan Stanley is an internationally recognized investment banking 
and advisory firm. Morgan Stanley, as part of its investment banking 
business, is continually engaged in the valuation of businesses and 
securities in connection with mergers and acquisitions, negotiated 
underwriting, competitive biddings, secondary distributions of listed and 
unlisted securities, private placements and valuations for corporate and 
other purposes. Morgan Stanley is a full-service securities firm engaged in 
securities trading and brokerage activities, as well as providing investment 
banking and financial advisory services. In the ordinary course of its 
trading and brokerage activities, Morgan Stanley or its affiliates may at any 
time hold long or short positions, and may trade or otherwise effect 
transactions, for its own account or the accounts of customers, in securities 
of Orion, Loral or Globalstar. In the past, Morgan Stanley and its affiliates 
have provided financial advisory and investment banking services to Orion, 
for which services Morgan Stanley has received customary fees, including 
acting as lead underwriter in connection with a public offering of high-yield 
notes and warrants in January 1997 for which Morgan Stanley earned an 
underwriting discount and commission of $16.8 million. 

   Pursuant to an engagement letter between Orion and Morgan Stanley, Orion 
agreed to pay Morgan Stanley (i) an advisory fee estimated to be $250,000 in 
the event the Merger is not consummated, and (ii) if the Merger is 
consummated, a transaction fee equal to approximately $4.8 million, assuming 
a $17.50 price per share at closing. This transaction fee will vary depending 
on the Determination Price, and consequently the value per share received by 
Orion stockholders, at closing. In addition to the foregoing compensation, 
Orion agreed to reimburse Morgan Stanley for its expenses, including 
reasonable fees and expenses of its counsel, and to indemnify Morgan Stanley 
for liabilities and expenses arising out of the engagement and the 
transactions in connection therewith, including liabilities under federal 
securities laws. 

LORAL'S REASONS FOR THE TRANSACTIONS 

   Loral is undertaking the Merger in furtherance of its long-term strategy 
to expand the range of its geosynchronous satellite service businesses 
internationally. Orion's business was deemed an attractive acquisition 
candidate because of the orbital location of Orion 1 and the proposed 
locations for the Orion satellites under construction, the experience of 
Orion management and personnel in European operations, the expertise of Orion 
in value added satellite services and satellite-supported data networking, 
all of which, Loral believes, will complement the businesses of Skynet and 
CyberStar. Loral also believes that the business of Orion will benefit from 
the market position and marketing expertise of Skynet, the technological 
expertise of SS/L and the superior financial resources of Loral. 

CONVERSION OF ORION CAPITAL STOCK 

   Exchange Ratio. At the Effective Time, each share of Orion Common Stock 
issued and outstanding immediately prior to the Effective Time, excluding 
treasury shares and shares owned by Loral or any subsidiary of Loral, will be 
converted into the right to receive that number of fully paid and 
nonassessable shares of Loral Common Stock equal to the Exchange Ratio. 
Shares of Orion Capital Stock owned by 

                                       45
<PAGE>
Loral or any subsidiary of Loral will be converted into the right to receive 
such fully paid and nonassessable shares of the Surviving Corporation as 
necessary in order to ensure that such entity's proportionate interest in the 
Surviving Corporation immediately after the Effective Time will be equal to 
such entity's proportionate interest in Orion immediately prior to the 
Effective Time. 

   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 Loral 
    Common Stock for the twenty consecutive trading days on which trading of 
    Loral Common Stock occurs ending the tenth trading day immediately prior 
    to the closing date for the 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. 

   For each whole dollar Determination Price from $15 through $26, as well as 
for a Determination Price equal to $16.305, $20.3815 and $24.458 (the low, 
middle and high end of the Determination Price range), the following table 
sets forth (i) Exchange Ratio and (ii) the dollar value of each share of 
Loral Common Stock that Orion stockholders would receive in the Merger in 
exchange for shares of Orion Common Stock:

Loral Common Stock remains between $16.305 and $24.458, the intended economic 
effect of the Merger is to provide Orion stockholders with $17.50 worth of 
Loral Common Stock in exchange for each share of Orion Common Stock. As the 
above table also illustrates, if the Determination Price of Loral Common 
Stock is greater than $24.458, or less than $16.305, Orion stockholders will 
receive a maximum of 1.07329 and a minimum of 0.71553 shares, respectively, 
of Loral Common Stock in exchange for each share of Orion Common Stock, which 
would provide Orion stockholders with Loral Common Stock having a value that 
is greater than $17.50 (in the case of a Determination Price greater than 
$24.458) or less than $17.50 (in the case of a Determination Price less than 
$16.305). 

   By way of illustration, if the Merger occurred as of February 12, 1998 and 
all Orion stockholders exchanged their Orion stock (excluding treasury shares 
and shares owned by Loral or its subsidiaries), there would have been 
approximately 24,878,000 shares of Orion Common Stock exchanged for Loral 
Common Stock. Based on assumed Determination Prices of $15 and $26, the 
approximately 24,878,000 

                                       46
<PAGE>
shares of Orion Common Stock would have been exchanged for 26,701,309 
(representing a beneficial ownership of approximately 13.3% of Loral Common 
Stock) and 17,800,956 shares of Loral Common Stock (representing a beneficial 
ownership of approximately 8.9% of Loral Common Stock), respectively. 

   From February 23, 1998 until the date of the Merger, Orion stockholders 
can call (301) 721-2626 and listen to a recording of what the Exchange Ratio 
would be if the Merger occurred on the day of the phone call. 

   Each share of Orion Preferred Stock issued and outstanding immediately 
prior to the Effective Time, excluding treasury shares and shares owned by 
Loral or any subsidiary of Loral, will be converted into the right to receive 
the number of fully paid and nonassessable shares of Loral Common Stock equal 
to the Exchange Ratio multiplied by the number of shares of Orion Common 
Stock into which such share of Orion Preferred Stock was convertible 
immediately prior to the Effective Time. 

   Each share of Loral Common Stock issued in connection with the Merger will 
be accompanied by one Loral Right. 

   Possible Adjustments. If, prior to the Effective Time, the outstanding 
number of shares of Orion Capital Stock or Loral Common Stock are 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 is declared thereon with a 
Record Date within such period, the Exchange Ratio shall be adjusted 
accordingly to provide the holders of shares of Orion Capital Stock with the 
same economic effect as contemplated by the Merger Agreement prior to such 
reclassification, recapitalization, split-up, combination, exchange or 
dividend. 

   Fractional Shares. No fractional share of Loral Common Stock will be 
issued in the Merger. In lieu of any such fractional shares, each holder 
entitled to receive a fractional share will be paid cash (without interest) 
in an amount equal to the product of (a) such fractional interest to which 
such holder otherwise would be entitled and (b) the last sales price per 
share of Loral Common Stock on the NYSE Composite Transactions reporting 
system for the closing date of the Merger. As promptly as practicable after 
the determination of the amount of cash, if any, to be paid to holders of 
fractional interests, Loral shall cause the Surviving Corporation to deposit 
with the Exchange Agent the cash necessary for such purpose and shall cause 
the Exchange Agent to forward payments to such holders of fractional 
interests subject to the terms of the Merger Agreement. 

   Interest and Dividend Shares. To the extent that any interest accrued or 
payable with respect to the Debentures or any dividends accrued or payable 
with respect to the Orion 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 shares of fully paid and non-assessable Loral Common 
Stock equal to the Exchange Ratio multiplied by the number of shares of Orion 
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 converted under the terms of their governing 
instruments, such interest and dividends shall be paid in Orion Common Stock 
immediately prior to the Effective Time and converted as Orion Common Stock. 

EXCHANGE OF CERTIFICATES IN THE MERGER 

   As of the Effective Time, all shares of Orion Capital Stock shall no 
longer be outstanding and shall automatically be canceled and retired and 
shall cease to exist, and, immediately prior to the Effective Time, each 
holder of a certificate representing any such shares of Orion Capital Stock 
shall cease to have any rights with respect thereto, except as otherwise 
provided in the Merger Agreement or by law. Loral shall, on behalf of Merger 
Subsidiary, deposit with the Exchange Agent for the benefit of the holders of 
shares of Orion Capital Stock, excluding treasury shares and shares owned by 
Loral or any subsidiary of Loral, the shares of Loral Common Stock issuable 
pursuant to the Merger Agreement plus cash in an amount sufficient to make 
payment for fractional shares. Promptly after the Effective Time, the 
Exchange Agent will mail a transmittal letter and instructions to each holder 
of record of certificates which immediately prior to the Effective Time 
represented outstanding shares of Orion Capital Stock. Upon surrender to the 
Exchange Agent of a certificate which immediately prior to the Effective Time 

                                       47
<PAGE>
represented outstanding shares of Orion Capital Stock, together with such 
letter of transmittal duly executed, and any other required documents, the 
holder of such certificate shall be entitled to receive in exchange therefor 
the applicable merger consideration and such certificate shall forthwith be 
canceled. ORION STOCKHOLDERS ARE REQUESTED NOT TO SURRENDER THEIR 
CERTIFICATES FOR EXCHANGE UNTIL SUCH TRANSMITTAL LETTER AND INSTRUCTIONS ARE 
RECEIVED. Until surrendered in accordance with the provisions of the Merger 
Agreement, each certificate shall represent for all purposes only the right 
to receive the applicable merger consideration, without any interest thereon. 
In the event any certificate evidencing shares of Orion 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 Loral or the Exchange Agent with respect to such 
certificate, Loral shall cause the Exchange Agent to pay to such person the 
merger consideration with respect to such lost, stolen or destroyed 
certificate. 

CONVERSION OF OPTIONS AND WARRANTS; STOCK PURCHASE PLAN 

   As of the Effective Time (i) each outstanding option to purchase Orion 
Common Stock (an "Option") will be converted into an option (a "Converted 
Option") to acquire, on the same terms and conditions that were applicable 
under such Option, a number of whole shares of Loral Common Stock equal to 
the product of the aggregate number of shares of Orion Common Stock for which 
such Option was exercisable multiplied by the Exchange Ratio; and (ii) the 
exercise price per share of Loral Common Stock 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 Loral Common Stock for 
which such Option shall be exercisable as determined above and rounded to the 
next highest whole cent. Each outstanding warrant to purchase Orion Common 
Stock (a "Warrant") will be converted into a warrant (a "Converted Warrant") 
to acquire on the same terms and conditions that were applicable under such 
Warrant, a number of whole shares of Loral Common Stock equal to the product 
of the aggregate number of shares of Orion Common Stock for which such 
warrant was exercisable times the Exchange Ratio, and the exercise price per 
share of Loral Common Stock issuable pursuant to such Warrant shall be equal 
to the aggregate exercise price for such Warrant at the Effective Time 
divided by the number of shares of Loral Common Stock for which such Warrant 
shall be exercisable as determined above and rounded to the next highest 
whole cent. 

   No Option or Warrant shall be exercisable for fractional shares. Each 
holder of an Option or Warrant exercisable for a fractional share of Loral 
Common Stock shall be entitled to receive, upon exercise thereof, an offset 
against the aggregate exercise price of the Option or Warrant being exercised 
equal to the product of the fraction of a share of Loral Common Stock to 
which a holder of such Option or Warrant would be entitled to receive times 
the excess of the closing price of a share of Loral Common Stock as reported 
on the NYSE on the date of exercise over the exercise price for such Option 
or Warrant. 

   Loral, on behalf of Merger Subsidiary, will take all corporate action 
necessary to reserve for issuance a sufficient number of shares of Loral 
Common Stock for delivery upon exercise of the Options and Warrants. Loral 
will file one or more registration statements on Form S-8 to become effective 
as soon as practicable after the Effective Time, with respect to the Loral 
Common Stock subject to Options granted under the Orion stock option plans 
and will 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. As soon as practicable following the Effective Time, Loral 
shall, on behalf of Merger Subsidiary, take such other actions as are 
reasonably necessary to revise and adjust each Option and each Warrant, 
including providing the holder of each Option and each Warrant with an 
appropriate option agreement or warrant agreement, respectively, or amendment 
to existing option agreement or warrant agreement, respectively. Except as 
set forth in the Merger Agreement, the conversion of Options 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 obligations or restrictions applicable to their Options or the 
shares obtainable upon exercise of the Options. 

                                       48

   In connection with the Merger, Orion has amended its employee stock option 
plans to provide that in the event an optionee's employment is terminated 
within two years after a "Change in Control" (as defined) by Orion other than 
for "Cause" (as defined) or by the optionee for "Good Reason" (as defined), 
all non-vested Options held by the optionee under such plans will immediately 
vest. "Cause" includes certain criminal acts, willfully failure to perform 
material assigned duties and gross or willful misconduct that causes 
substantial harm to Orion's business. "Good Reason" means any reduction in 
optionee's base salary (with certain exceptions), substantially reduction of 
responsibilities or relocation outside the metropolitan areas in which 
offices of Orion were located immediately prior to the Change in Control. 

   Effective as of the last trading day of Orion Common Stock prior to the 
Effective Time, the then applicable payroll deduction period, as defined in 
Orion's 1996 Employee Stock Purchase Plan, shall be terminated and the rights 
of all participating employees shall be deemed to be automatically exercised 
as of such last trading day of Orion Common Stock. 

INTERESTS OF CERTAIN PERSONS IN THE MERGER 

   Certain members of Orion's management and Board of Directors have certain 
interests in the Merger that are in addition to the interests of stockholders 
of Orion generally. These interests arise from, among other things, certain 
employee benefit plans and indemnification and insurance arrangements which 
Loral will assume or has agreed to provide after the Merger. 

   As of the Record Date, directors and executive officers of Orion owned (i) 
2,363,698 shares of Orion Common Stock and 1,454 shares of Orion Preferred 
Stock (for which they will receive the same consideration as other Orion 
stockholders) and (ii) options to acquire 901,236 shares of Orion Common 
Stock. The stock and options held by such directors and executive officers 
will be treated in the Merger in a manner identical to stock and options held 
by other persons, except that directors and executive officers of Orion, as 
affiliates of Orion for purposes of Rule 145 under the Securities Act, will 
be subject to certain limitations on resale of Loral Common Stock and that, 
under the proposed amendments to the Director Option Plan (see "Amendments to 
Director Option Plan"), options issued to Orion's directors under the 
Director Option Plan will vest upon consummation of the Merger instead of at 
the next annual meeting of Orion stockholders. 

   As a condition to entering into the Merger Agreement, Loral required 
certain stockholders of Orion to enter into the Principal Stockholder 
Agreement pursuant to which such stockholders (i) agreed to vote their shares 
of Orion Common Stock in favor of the approval of the Merger Agreement and 
against any proposal for any recapitalization, merger (other than the 
Merger), sale of assets or other business combination between Orion and any 
person or entity (other than Loral and Merger Subsidiary) or any other action 
or agreement that would result in a breach of the Merger Agreement or result 
in any condition of the Merger Agreement not being fulfilled, (ii) granted 
irrevocable proxies in favor of Loral and Merger Subsidiary to so vote their 
shares, (iii) granted to Loral an option to purchase such stockholders' 
shares of Orion Common Stock and Orion Preferred Stock for the Exchange 
Ratio, and (iv) one such stockholder, British Aerospace Holdings, Inc., 
granted to Loral an option to require the conversion of all (but not less 
than all) of its Debentures into Orion Common Stock and, upon such 
conversion, the option to purchase such shares for the Exchange Ratio. The 
options described in (iii) and (iv) above may only be exercised upon the 
occurrence of certain events, which generally relate to, or are designed to 
culminate in, the acquisition of control of, or a significant equity interest 
in or significant assets of, Orion by a third party. See "The Principal 
Stockholder Agreement." See "The Merger Agreement and Principal Stockholder 
Agreement -- Principal Stockholder Agreement." 

   Under the Merger Agreement, Loral and Orion have agreed that the 
certificate of incorporation and bylaws of the Surviving Corporation will 
contain the provisions for indemnification set forth in Orion's certificate 
of incorporation and bylaws for a period of six years after the Effective 
Time unless otherwise required by law. Loral has agreed to cause the 
Surviving Corporation to indemnify, defend and hold harmless the present and 
former officers, directors and employees of Orion and Orion's subsidiaries 
against losses arising out of actions or omissions occurring at or prior to 
the Effective Time to the fullest 

                                       49
<PAGE>
extent permitted under Delaware law, and agreed to maintain in effect for six 
years the current policies of directors' and officers' liability insurance 
and fiduciary liability insurance maintained by Orion with respect to matters 
occurring prior to the Effective Time. 

   In addition, Loral has agreed to cause the Surviving Corporation to 
provide employee benefits under plans, programs and arrangements, which, in 
the aggregate, will provide benefits to the employees of Orion and its 
subsidiaries, which are not less favorable, in the aggregate, than those 
provided pursuant to the plans, programs and arrangements of Orion in effect 
on the date of the Merger Agreement. 

   Loral has also acknowledged and agreed that prior to the Effective Time, 
Orion will take all actions as may be necessary to cause (i) all participants 
to become fully vested in their benefits under Orion's 401(k) plan, and (ii) 
employer contributions to be made with respect to periods prior to the 
Effective Time to Orion's 401(k) plan to the extent that such contributions 
would be made if the participants were employed by Orion on the last day of 
the calendar year in which the closing occurs. 

   In addition, SS/L owned, as of February 12, 1998, 588,235 shares of Orion 
Common Stock, equal to approximately 2.7% of the voting stock of Orion 
outstanding as of such date. 

   Loral has agreed to pay a $1 million finder's fee to C.E. Unterberg, 
Towbin in connection with the Merger. A. Robert Towbin, a principal of C.E. 
Unterberg, Towbin, is a director of Globalstar. 

FEES AND EXPENSES 

   All fees and expenses incurred in connection with the Merger, the Merger 
Agreement and the transactions contemplated thereunder shall be paid by the 
party incurring such fees or expenses, whether or not the Merger is 
consummated. 

ACCOUNTING TREATMENT 

   The Merger will be accounted for using the purchase method of accounting. 
Under the purchase method of accounting, the purchase price of Orion, 
including direct costs of the Merger, will be allocated to the identifiable 
assets acquired and liabilities assumed based upon their estimated relative 
fair values, with the excess purchase consideration allocated to goodwill. 
The results of Loral's operations will include the results of operations of 
Orion commencing at the Effective Time. 

   The Pro Forma Financial Data describing the pro forma effects of the 
Merger appearing elsewhere in this Proxy Statement/Prospectus are based upon 
certain assumptions and allocate the purchase price to assets and liabilities 
based upon their historical values, pending completion of an independent 
valuation and allocation of their respective fair values, which are not 
expected to result in material adjustments. The unaudited pro forma 
adjustments and combined amounts are included for informational purposes 
only. If the Merger is consummated, Loral's financial statements will reflect 
the effects of acquisition adjustments only from the Effective Time. The 
actual allocation of the purchase price may differ significantly from the 
allocation reflected in the Pro Forma Financial Data. 

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER 

   General. The following discussion summarizes certain material U.S. federal 
income tax consequences of the Merger to U.S. holders of Orion Common Stock 
and Orion Preferred Stock (assuming such Orion Common Stock and Orion 
Preferred Stock are held as capital assets) and does not purport to be a 
complete analysis or listing of all potential tax effects relevant to a 
decision whether to vote in favor of the Merger. The discussion is for 
general information purposes only and does not take into account the 
particular circumstances of any individual holder of Orion Common Stock and 
Orion Preferred Stock and does not address the tax consequences that may be 
relevant to holders of Orion Common Stock and Orion Preferred Stock with 
special tax status, including but not limited to financial institutions, 
insurance companies, dealers in securities, holders that are not citizens or 
residents of the United States and tax-exempt entities, or to holders that 
acquired Orion Common Stock upon the exercise of employee stock options or 
otherwise as compensation. Moreover, the discussion does not address any 
consequences arising under the laws of any state, locality or foreign 
jurisdiction. Additionally, the tax consequences to holders of stock options 
are not discussed. 

                                       50
<PAGE>
   The discussion is based on the Code, Treasury Regulations thereunder and 
administrative rulings and court decisions as of the date of the Tax Opinion 
(see below). All of the foregoing are subject to change and any such change 
could adversely affect the opinions expressed in the Tax Opinion 
retroactively. Holders of Orion Common Stock and Orion Preferred Stock are 
urged to consult with their own tax advisors regarding the tax consequences 
of the Merger to them, including the effects of federal, state, local, 
foreign and other tax laws. 

   TAX TREATMENT UNCERTAIN DUE TO SPECIAL CONSIDERATIONS. The U.S. federal 
income tax treatment of the Merger is uncertain due to special considerations 
discussed below because of Loral's status as a foreign corporation. Subject 
to such considerations, Orion and Loral expect that the Merger would 
constitute a "reorganization" within the meaning of Section 368(a) of the 
Code and that for U.S. federal income tax purposes no gain or loss would be 
recognized by U.S. stockholders of Orion upon the receipt of Loral Common 
Stock in exchange for Orion Common Stock or Orion Preferred Stock pursuant to 
the Merger (except with respect to the receipt of cash by a holder of Orion 
Common Stock or Orion Preferred Stock in lieu of a fractional share interest 
in Loral Common Stock). 

   However, special considerations under Section 367 of the Code because of 
Loral's status as a foreign corporation may result in the Merger not 
constituting a "reorganization" within the meaning of Section 368(a) of the 
Code, so that for U.S. federal income tax purposes gain, but not loss, would 
be recognized by U.S. stockholders of Orion upon the receipt of Loral Common 
Stock in exchange for Orion Common Stock or Orion Preferred Stock pursuant to 
the Merger. Such gain would be in an amount equal to the excess, if any, of 
the fair market value of the Loral Common Stock received over the Orion 
stockholders' adjusted tax basis in the Orion Common Stock or Orion Preferred 
Stock exchanged therefor. THERE CAN BE NO ASSURANCES AS TO WHETHER ORION 
STOCKHOLDERS WILL BE REQUIRED TO RECOGNIZE GAIN REALIZED FOR U.S. FEDERAL 
INCOME TAX PURPOSES AS A RESULT OF THE MERGER. 

   Tax Treatment as a "Reorganization," EXCLUDING EFFECT OF SPECIAL 
CONSIDERATIONS. On or prior to the Effective Date, Ernst & Young LLP, tax 
advisor to Orion, is expected to deliver to Orion its opinion (the "Tax 
Opinion") addressing and limited to the following issues. Subject to the 
special considerations because of Loral's status as a foreign corporation 
under Section 367 of the Code: (i) the Merger will constitute a 
"reorganization" within the meaning of Section 368(a) of the Code, (ii) 
Loral, Merger Subsidiary and Orion will each be a party to the reorganization 
within the meaning of Section 368(b) of the Code, (iii) no income, gain or 
loss will be recognized for U.S. federal income tax purposes by either Loral 
or Orion as a result of the Merger, (iv) no income, gain or loss will be 
recognized for U.S. federal income tax purposes by U.S. stockholders of Orion 
upon the exchange in the Merger of Orion Common Stock and Orion Preferred 
Stock solely for Loral Common Stock (except to the extent of any cash 
received in lieu of fractional shares), (v) the tax basis of Loral Common 
Stock received by each U.S. stockholder of Orion will be the same as the tax 
basis of such stockholder's Orion Common Stock and Orion Preferred Stock 
exchanged therefor, reduced by any amount allocable to a fractional share 
interest for which cash is received, and (vi) the holding period of Loral 
Common Stock in the hands of the U.S. stockholders of Orion will include the 
holding period of such stockholder's Orion Common Stock and Orion Preferred 
Stock exchanged therefor, provided that such Stock is held as a capital asset 
at the Effective Time. 

   Special Tax Considerations. Because Loral (as a Bermuda company) is a 
foreign corporation, certain special rules under Section 367 of the Code 
regarding mergers involving foreign corporations apply to the Merger. In 
general, under Section 367 of the Code, gain realized by U.S. stockholders in 
an otherwise tax-free reorganization involving domestic and foreign 
corporations will be taxable unless the parties satisfy certain objective 
criteria set forth in relevant Treasury Regulations under Section 367 of the 
Code. Those criteria include, among other things, (i) the amount of Loral 
stock which is received by the domestic Orion stockholders in the Merger 
cannot exceed 50% of Loral's outstanding stock; (ii) the post-Merger amount 
of Loral stock held by certain 5% U.S. stockholders of Orion and U.S. 
officers and directors of Orion, both individually and collectively, in Loral 
cannot exceed 50% of Loral's outstanding stock (counting for this purpose 
Loral stock held or treated as held by those Orion stockholders, officers, 
and directors, prior to the Merger); and (iii) Loral must satisfy a detailed 
active trade or business requirement for the thirty-six month period 
immediately prior to the Merger (the "Active Trade or 

                                       51
<PAGE>
Business Requirement"). In addition, in order to defer recognition of gain 
each Orion stockholder owning five percent or more of the stock of Loral 
immediately after the Merger must enter into an agreement to recognize gain 
as of the Effective Time in the event Loral disposes of the Orion shares 
within a five (and in certain cases, ten) year period following the year in 
which the transfer takes place. Orion and Loral management believe that the 
limitations in clause (i) and (ii) above should be met with respect to the 
Merger. 

   The Active Trade or Business Requirement is based on activities conducted 
outside the U.S. by a company directly or through one or more qualified 
subsidiaries and/or partnerships. Therefore, the determination of whether 
Loral satisfies the Active Trade or Business Requirement is based on numerous 
factual matters relating to the business conducted outside of the U.S. by 
Loral and its qualified subsidiaries and/or partnerships and the application 
of the relevant regulations and other interpretive guidance to such factual 
matters. In addition, the application of the Active Trade or Business 
Requirement to Loral's historical business activities is unclear because 
there is limited guidance as to the nature of the activities necessary to 
satisfy that rule. Furthermore, the IRS recognizes that it may be appropriate 
to treat transactions that substantially comply with the Active Trade or 
Business Requirement as non-taxable even though all aspects of the Active 
Trade or Business Requirement are not strictly satisfied. IRS regulations 
expressly invite companies who believe, as Loral and Orion do, that their 
transaction should not be taxable to apply for a tax ruling that the 
transaction will be treated as non-taxable. However, the IRS has not yet 
considered such a request. Accordingly, there is no guidance as to what 
circumstances the IRS will consider in determining whether it will treat a 
transaction as non-taxable. Without such guidance, Loral and Orion cannot 
determine how the IRS will treat the transaction. 

   Therefore, under the Merger Agreement, Loral and Orion have agreed and 
plan to seek to obtain, a private letter ruling from the IRS that Loral will 
be treated as a corporation for purposes of Section 367(a) of the Code. The 
information to be collected in preparing the ruling request has not been 
completed. Depending on the additional information which is collected, the 
request will (i) seek a ruling that Loral satisfies the Active Trade or 
Business Requirement and/or (ii) request that the IRS exercise its authority 
under Section 367 regulations and treat Loral as a foreign corporation for 
purposes of Section 367(a) of the Code even though such requirement is not 
satisfied. If a ruling is obtained and all other applicable requirements are 
satisfied, the Merger will qualify as a tax-free reorganization under Section 
368(a) of the Code. In addition, Loral has agreed that it will not, and will 
not permit any of its subsidiaries, to intentionally take, fail to take, or 
cause to be taken or not taken any action within its control that would 
disqualify the Merger as a reorganization within the meaning of Section 
368(a) of the Code. 

   Loral and Orion do not expect to receive any such ruling until after the 
Effective Time. Loral and Orion intend to proceed with the Merger while such 
ruling is being sought, and receipt of a favorable ruling from the IRS is not 
a condition to consummation of the Merger. Loral and Orion intend to continue 
to pursue such ruling after the Effective Time, if necessary, and, if such 
ruling is received, they will notify any U.S. stockholder of Orion as of the 
Effective Time as to the outcome of the request. Unless a favorable ruling is 
obtained from the IRS, based on the facts as they exist as of the date of 
this Proxy Statement/Prospectus, Loral intends to take the position that the 
Merger is a taxable transaction and, accordingly, any Orion stockholders that 
realized gain, but not loss, as a result of the Merger will be required to 
recognize such gain for U.S. federal income tax purposes. The grant or denial 
of the proposed ruling request is within the discretion of the IRS and no 
comparable private rulings have ever been issued. Accordingly, there can be 
no assurance that a favorable ruling will be granted in this case. 

   Tax Treatment ASSUMING GAIN ON THE MERGER MUST BE RECOGNIZED Due to 
Special Considerations. The Tax Opinion is expected to state that if the 
Section 367 rules do require the recognition of gain: (i) each U.S. Orion 
stockholder recognize gain upon the receipt of Loral Common Stock in exchange 
for Orion Common Stock or Orion Preferred Stock pursuant to the Merger in an 
amount equal to the excess, if any, of the fair market value of the Loral 
Common Stock received over the Orion stockholders' adjusted tax basis in the 
Orion Common Stock or Orion Preferred Stock exchanged therefor, (ii) such 
gain will constitute long-term capital gain if, at the Effective Time, such 
stockholder's Orion Common Stock and Orion Preferred Stock is held as a 
capital asset and has been held for more 

                                       52
<PAGE>
than 18 months, (iii) any U.S. Orion stockholder that realizes a loss upon 
the receipt of Loral Common Stock in exchange for Orion Common Stock or Orion 
Preferred Stock pursuant to the Merger will not be entitled to recognize such 
loss for U.S. federal income tax purposes, (iv) any U.S. Orion stockholder 
that realizes gain for U.S. federal income tax purposes upon the Merger will 
have a tax basis in the Loral Common Stock received equal to its fair market 
value, and the holding period of Loral Common Stock in the hands of such 
Orion stockholder will begin on the day following the Effective Time, and (v) 
any U.S. Orion stockholder that realizes but is unable to recognize a loss 
for U.S. federal income tax purposes upon the exchange will have a tax basis 
in the Loral Common Stock received equal to the tax basis of such 
stockholder's Orion Common Stock and Orion Preferred Stock exchanged 
therefor, and the holding period of Loral Common Stock in the hands of such 
Orion stockholder will include the holding period of such stockholder's Orion 
Common Stock and Orion Preferred Stock exchanged therefor. 

   Tax Treatment of Cash Received in Lieu of Fractional Shares. Regardless of 
the tax treatment of Loral Common Stock received by Orion stockholders 
discussed above, a holder of Orion Common Stock and Orion Preferred Stock who 
receives cash in lieu of a fractional share of Loral Common Stock will 
recognize gain or loss equal to the difference between the amount of such 
cash and the tax basis allocated to such stockholder's fractional share of 
Loral Common Stock. Such gain or loss will constitute long-term capital gain 
or loss if, at the Effective Time, such stockholder's Orion Common Stock and 
Orion Preferred Stock is held as a capital asset and has been held for more 
than 18 months. 

   Opinion of Tax Advisors Based on Representations made by Orion and Loral 
and on Current Law. The Tax Opinion referred to above is based on 
representations made by Orion, Loral and certain significant Orion 
stockholders, which representations Ernst & Young LLP has not independently 
verified. The Tax Opinion is based upon the Merger taking place as described 
in the Merger Agreement and that certain factual matters with respect to 
Loral, Merger Subsidiary and Orion, respectively, described in certain 
representation letters to be delivered to Ernst & Young LLP prior to the 
issuance of its Tax Opinion, will be true, complete and correct as of the 
Effective Time. Such representation letters include, among other things, 
representations relating to the continued ownership of a sufficient amount of 
Loral stock by historic stockholders of Orion, the absence of plans to engage 
in certain transactions with respect to Merger Subsidiary and the assets of 
Orion, the continued operation of Orion's historic business after the Merger, 
payment of Merger expenses, limitation on cash paid for fractional shares in 
connection with the Merger, and the nature of compensation paid to 
employee-stockholders and the officers and directors of Orion after the 
Merger. The Tax Opinion will be based on current laws and interpretations 
thereof as of the date of the Tax Opinion, including the Code, the 
regulations promulgated thereunder, administrative rulings and practice and 
judicial authority. All of these authorities are subject to change, possibly 
with an adverse effect on the opinions expressed in the Tax Opinion that 
could be applied retroactively. Ernst & Young LLP is not responsible for 
updating its opinion for any such change which may occur subsequently to the 
date of the Tax Opinion. The Tax Opinion is not binding on the IRS and there 
can be no assurance, and none is hereby given, that the IRS will not take a 
position contrary to one or more positions reflected in such opinions or that 
such opinions will be upheld by the courts if challenged by the IRS. 

   THE DISCUSSION SET FORTH ABOVE IS FOR GENERAL INFORMATION PURPOSES ONLY. 
THE DISCUSSION IS BASED ON CURRENTLY EXISTING PROVISIONS OF THE CODE, 
EXISTING AND PROPOSED TREASURY REGULATIONS THEREUNDER AND CURRENT 
ADMINISTRATIVE RULINGS AND COURT DECISIONS, ALL OF WHICH ARE SUBJECT TO 
CHANGE. ANY SUCH CHANGE, WHICH MAY OR MAY NOT BE RETROACTIVE, COULD ALTER THE 
TAX CONSEQUENCES DESCRIBED ABOVE. STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN 
TAX ADVISORS AS TO SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING 
THE APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL AND OTHER APPLICABLE 
TAX LAWS AND THE POSSIBLE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS. 

TAXATION OF LORAL AND ITS STOCKHOLDERS 

   The discussion of U.S. tax law is based upon the opinion of Willkie Farr & 
Gallagher, special U.S. counsel to Loral. The summary of certain Bermuda tax 
consequences is based upon the opinion of Appleby, Spurling & Kempe, Bermuda 
counsel to Loral.

UNITED STATES TAX CONSIDERATIONS 

   Taxation of Loral. Loral will be subject to U.S. Federal, state and local 
income taxation at regular corporate rates on any income that is effectively 
connected with the conduct of a U.S. trade or business. When such income is 
deemed removed from the U.S. business, it will be subject to an additional 30 
percent "branch profits" tax. Based upon counsel's opinion as to the source 
of income and effective connection rules that are applicable, Loral expects 
that a significant portion of its income will be from foreign sources and 
will not be effectively connected with the conduct of a U.S. trade or 
business. The IRS may disagree and/or may promulgate regulations that would 
recharacterize a substantial portion of Loral's income as from United States 
sources and as effectively connected with a U.S. trade or business so as to 
subject that income to regular United States income and branch profits taxes. 

   Any U.S. subsidiaries, such as SS/L and Orion, will be subject to regular 
U.S. taxes on their worldwide income. In addition, a 30% U.S. withholding tax 
will be imposed on dividends and interest paid by such corporations to Loral. 

   Loral expects that a significant portion of its worldwide income will not 
be subject to tax by the United States, Bermuda or by other countries from 
which it derives income. However, some portion of Loral's income from sources 
outside the United States, realized through Globalstar or otherwise, will be 
subject to taxation by foreign countries and the extent to which certain 
countries may require Loral or Globalstar to pay tax or to make payments in 
lieu of tax cannot be determined in advance. 

   Taxation of Non-U.S. Securityholders in Loral. A non-U.S. resident alien 
individual, a non-U.S. corporation, a non-U.S. trust or a non-U.S. estate 
holding shares in Loral (a "Securityholder") will not be subject to U.S. 
Federal income taxation on payments of dividends on the shares he holds in 
Loral unless those payments are (i) effectively connected with the conduct by 
the Securityholder of a trade or business in the United States or (ii) 25% or 
more of Loral's gross income for a certain period (generally three years) 
prior to the year of the payment was treated as effectively connected with 
trades or businesses conducted by Loral in the United States. In this latter 
case, a proportionate part of any payment, corresponding to the percentage of 
Loral's gross income that is deemed effectively connected with Loral's United 
States trades and businesses, would be subject to a 30% (or lower treaty 
rate) U.S. withholding tax. Consistent with the discussion above, Loral 
expects that less than 25% of its income in any year will be effectively 
connected with the conduct of a trade or business in the United States. 

   In addition, such a non-U.S. Securityholder will not be subject to U.S. 
Federal income taxation on gains realized by the Securityholder on a sale or 
exchange of Shares he holds in Loral unless the sale of such shares is 
attributable to an office or fixed place of business maintained by the 
Securityholder in the United States or the Securityholder is an individual 
who is present in the United States for 183 or more days during the year of 
sale and who have either a tax home or an office or other fixed place of 
business in the United States to which the offer or exchange is attributable. 
The determination of whether a Securityholder is engaged in the conduct of a 
trade or business in the United States or whether the sale of a 
Securityholder's shares in Loral is attributable to an office or fixed place 
of business of the Securityholder in the United States depends on the facts 
and circumstances of each Securityholder's case. Each Securityholder should 
consult with his own tax advisor to determine whether his payments or gains 
with respect to a Security will be subject to U.S. federal income taxation. 

   Taxation of United States Securityholders in Loral. A Securityholder 
holding a share in Loral as a capital asset will recognize capital gain or 
loss on a sale or other disposition of the share in Loral (other than in 
certain limited circumstances on a redemption by Loral). 

   To the extent Loral has undistributed current or accumulated earnings and 
profits, payment of dividends with respect to Loral's shares will be taxable 
dividend income to a Securityholder. Because Loral is not incorporated in the 
United States, the payments that are treated as dividends will not be 
eligible for the dividends received deduction. 

BERMUDA TAX CONSIDERATIONS 

   There is no Bermuda income tax, corporation or profits tax, withholding 
tax, capital gains tax, capital transfer tax, estate or stamp duty or 
inheritance tax payable by Loral or the holders of shares in Loral (other 
than holders who are ordinarily resident in Bermuda). 

                                       54
<PAGE>
   Loral has obtained from the Minister of Finance under the Exempted 
Undertakings Tax Protection Act 1966, as amended, a certificate confirming 
that, in the event of there being enacted in Bermuda, any legislation 
imposing tax computed on profits or income, or computed on any capital asset, 
gain or appreciation or any tax in the nature of estate duty or inheritance 
tax, such tax shall not until March 28, 2016 be applicable to Loral or to any 
of its operations, or other obligations of Loral except insofar as such tax 
applies to persons ordinarily resident in Bermuda and holding shares in Loral 
or other obligations, or to any land in Bermuda leased or let to Loral. 

   Loral has been classified as non-resident of the Bermuda exchange control 
area by the Bermuda Monetary Authority. The transfer of shares between 
persons regarded as non-resident of Bermuda for exchange control purposes and 
the issue and redemption of shares to and by such persons may be effected 
without specific consents under the Exchange Control Act 1972 of Bermuda and 
Regulations made thereunder. Transfers involving any person regarded as 
resident in Bermuda for exchange control purposes requires specific 
authorization under that Act. Loral by virtue of being a non-resident of 
Bermuda for exchange control purposes, is free to acquire, hold and sell any 
foreign currency, securities and other investments without restrictions. 

RESALE OF LORAL COMMON STOCK 

   The Loral Common Stock to be issued pursuant to the Merger will be freely 
transferable under the Securities Act except for shares issued to any Orion 
stockholder who, prior to the Merger, may be deemed an affiliate of Orion (an 
"Affiliate") as such term is defined under the Securities Act. Orion will use 
its reasonable efforts to cause each Affiliate to enter into an agreement 
with Loral providing that such Affiliate will not transfer any Loral Common 
Stock received in the Merger except in compliance with the Securities Act. 
Persons who may be deemed to be affiliates of Orion generally include 
individuals or entities that control, are controlled by, or are under common 
control with, Orion and may include certain officers and directors of Orion 
as well as principal stockholders of Orion. 

   Pursuant to the Principal Stockholder Agreement, BAe and Loral have agreed 
to consult and cooperate with respect to the orderly disposition of shares of 
Loral Common Stock obtained by BAe. BAe has agreed that for a period of 
twelve months from the date it acquires the shares of Loral Common Stock it 
will not and will cause each of its affiliates not to transfer any shares of 
Loral Common Stock 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 
defined). BAe will consult with Loral prior to such sale and seek the consent 
of Loral to such sale, which consent shall not be unreasonably withheld, 
conditioned or delayed. As an alternative to conducting block trades, BAe has 
the right to sell all (but not less than all) of its shares of Loral Common 
Stock pursuant to an underwritten sale with an underwriter reasonably 
acceptable to Loral. In addition, all of the stockholder parties to the 
Principal Stockholder Agreement have agreed pursuant to such agreement not to 
transfer Loral Common Stock received in the Merger except in compliance with 
the Securities Act. 

LISTING 

   It is a condition to the Merger that the shares of Loral Common Stock to 
be issued in connection with the Merger be authorized for listing on the 
NYSE, subject to official notice of issuance. 

CERTAIN EFFECTS OF THE PRINCIPAL STOCKHOLDER AGREEMENT AND TERMINATION FEE 

   As a condition to entering into the Merger Agreement, Loral required 
certain stockholders of Orion to enter into the Principal Stockholder 
Agreement pursuant to which such stockholders (i) agreed to vote their shares 
of Orion Common Stock in favor of the approval of the Merger Agreement and 
against any proposal for any recapitalization, merger (other than the 
Merger), sale of assets or other business combination between Orion and any 
person or entity (other than Loral and Merger Subsidiary) or any other action 
or agreement that would result in a breach of the Merger Agreement or result 
in any condition of the Merger Agreement not being fulfilled, (ii) granted 
irrevocable proxies in favor of Loral and Merger Subsidiary to so vote their 
shares, (iii) granted to Loral an option to purchase such 

                                       55
<PAGE>
stockholders' shares of Orion Common Stock and Orion Preferred Stock for the 
Exchange Ratio, and (iv) one such stockholder, BAe, granted to Loral an 
option to require the conversion of all (but not less than all) of its 
Debentures into Orion Common Stock and, upon such conversion, the option to 
purchase such shares for the Exchange Ratio. The options described in (iii) 
and (iv) above may only be exercised upon the occurrence of certain events, 
which generally relate to, or are designed to culminate in, the acquisition 
of control of, or a significant equity interest in or significant assets of, 
Orion by a third party. See "The Principal Stockholder Agreement." 

   Certain aspects of the Principal Stockholder Agreement, as well as certain 
aspects of the $20 million termination fee payable by Orion provided for in 
the Merger Agreement, may have the effect of discouraging persons who might 
now or prior to the consummation of the Merger be interested in acquiring all 
of or a significant interest in Orion from considering or proposing such an 
acquisition. See "The Merger Agreement -- Termination; Fees and Expenses" and 
"The Principal Stockholder Agreement -- Exercise of the Option." 

CERTAIN LEGAL MATTERS 

   Under the HSR Act and the rules promulgated thereunder by the Federal 
Trade Commission (the "FTC"), certain acquisition transactions may not be 
consummated unless notice has been given and certain information has been 
furnished to the Antitrust Division of the United States Department of 
Justice (the "Antitrust Division") and the FTC and certain waiting period 
requirements have been satisfied. The required waiting period under the HSR 
Act expired on November 21, 1997. 

   Notwithstanding the expiration of the HSR waiting period, state Attorneys 
General and private parties may also bring legal actions under the federal or 
state antitrust laws under certain circumstances. Based upon an examination 
of information available to Loral and Orion relating to the businesses in 
which Loral, Orion and their respective subsidiaries are engaged, Loral and 
Orion believe that the consummation of the Merger will not violate the 
antitrust laws. Nevertheless, there can be no assurance that a challenge to 
the proposed Merger on antitrust grounds will not be made or, if such a 
challenge is made, that Loral and Orion will prevail. 

   On October 16, 1997 Loral and Orion filed an application with the Federal 
Communications Commission ("FCC") seeking consent for Loral to acquire 
control of Orion and its affiliates. On October 22, 1997 the FCC placed the 
application on public notice and sought oppositions or petitions from 
interested parties with respect to the application within thirty (30) days. 
No comments were filed in response to the FCC's public notice by November 21, 
1997. Despite the passage of the filing deadline, there can be no assurance 
that parties will not file pleadings challenging grant of the application 
and, if such pleadings are filed, that the FCC will not consider any issues 
raised before acting on the application. 

   Although Loral anticipates that the FCC will grant the application, there 
can be no assurance that the FCC will do so. The FCC may, sua sponte, reject 
the application or place materially adverse conditions on any grant. Despite 
the fact that Loral and Orion seek to consummate the merger as promptly as 
practicable, the FCC may delay acting on the application. If the application 
is approved by the FCC, third parties may seek reconsideration or appeal of 
the FCC decision. There can be no assurance that these challenges will not 
prove successful. 

   Neither Loral nor Orion is aware of any other federal or state regulatory 
requirements or other requisitive approvals that may be required for 
consummation of the Merger except as described above. Should any such 
requirement or approval be required, it is presently contemplated that such 
requirement or approval would be sought. There can be no assurance, however, 
that any such requirement or approval, if needed, could be obtained and would 
not be conditioned in a manner that would cause the parties to abandon the 
Merger.

make or commit to make any investments or capital expenditures, other than

   (g) propose or adopt any amendments to its certificate of incorporation or

   (h) (i) make any significant change in any of its methods of accounting

suit, litigation, proceeding, arbitration, investigation, audit or 
controversy relating to taxes (except where the amount of such settlements or

December 31, 1996, except, in the case of clause (i) or clause (ii), as may 
be required by law or generally accepted accounting principles; 

   (i) incur any obligation for borrowed money, whether or not evidenced by a

arrangement, or understanding with, directly or indirectly, any of such 
entity's affiliates (as defined in Rule 12(b)-2 under the Exchange Act) which

entity, other than pursuant to such agreements, arrangements, or 
understandings (i) existing on the date of the Merger Agreement or (ii) which

   (k) surrender, agree to allow to expire or be terminated, modify 
adversely, forfeit, or fail to use reasonable best efforts to renew or extend

proceeding for the revocation, suspension, or adverse modification of any key 
Orion permit issued by the FCC or any Governmental Entity except for key 
Orion permits which lapse or expire due to ordinary course changes in the

Merger 

                                       60
<PAGE>
Agreement) or (ii) is not subject to termination by Orion upon less than six 
months written notice to the other party thereto, which in either case 
materially restricts or limits Orion's or any of its subsidiaries' right to 
conduct its business or compete, including, without limitation, any 
restriction on its ability to sell, lease or otherwise provide services from 
available transponder capacity to any person or entity for any purpose at any 
orbital location and in any frequency band, any geographical market segment, 
product line or other industry limitation, or any exclusive or sole supply or 
vendor arrangement or agreement. Nothing in the Merger Agreement shall 
preclude or require Orion or any of its subsidiaries from entering into 
agreements containing most favored nation provisions, options for additional 
services or capacity, rights of negotiation, or similar provisions, in each 
case in the ordinary course of business; or 

   (n) agree in writing or otherwise to do any of the foregoing. 

  Additional Covenants 

   Directors' and Officers' Indemnification and Insurance. Under the Merger 
Agreement, Loral and Orion have agreed that the certificate of incorporation 
and bylaws of the Surviving Corporation will contain the provisions for 
indemnification set forth in Orion's certificate of incorporation and bylaws 
for a period of six years after the Effective Time unless otherwise required 
by law. Loral has agreed to cause the Surviving Corporation to indemnify, 
defend and hold harmless the present and former officers, directors and 
employees of Orion and Orion's subsidiaries against losses arising out of 
actions or omissions occurring at or prior to the Effective Time to the 
fullest extent permitted under the DGCL. Loral has also agreed to maintain in 
effect for six years the current policies of directors' and officers' 
liability insurance and fiduciary liability insurance maintained by Orion 
with respect to matters occurring prior to the Effective Time. 

   Effect on Employee Benefit Plans. Loral has agreed to cause the Surviving 
Corporation to provide employee benefits under plans, programs and 
arrangements, which, in the aggregate, will provide benefits to the employees 
of Orion and its subsidiaries which are not less favorable, in the aggregate, 
than those provided pursuant to the plans, programs and arrangements of Orion 
in effect on the date of the Merger Agreement; provided, however, that 
nothing 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. 

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

   No Solicitation. Under the Merger Agreement, Orion has agreed that, prior 
to the Effective Time, it and its subsidiaries will not directly or 
indirectly encourage, initiate or solicit, from any third party proposals 
relating to, or enter into any agreement with respect to or accept any 
proposals or encourage, initiate or solicit the making of any proposal that 
constitutes, or that may reasonably be expected to lead to, a proposal of 
merger, consolidation or similar transaction, sale, lease or other 
disposition of assets of Orion or its subsidiaries representing 20% or more 
of their consolidated assets, or issue, sale or other disposition of 
securities representing 20% or more of the voting power of Orion or any 
transaction in which any person shall acquire or has the right to acquire 
beneficial ownership or any group which beneficially owns or has the right to 
acquire beneficial ownership of 35% or more of the Orion Common stock, unless 
such action is necessary for the directors to comply with their fiduciary 
duties to the stockholders under the DGCL (and Orion is required to notify 
Loral promptly of all of the relevant details relating to all inquiries and 
proposals which it may receive relating to any such matters). 

   Certain Other Covenants. Under the Merger Agreement, both Loral and Orion 
have agreed as follows: (a) to afford access to officers, employees, legal 
counsel, accountants, consultants and other representatives of the other 
party, during the period prior to the Effective Time, to their respective 
properties, executive personnel and all information concerning their 
respective businesses, properties, contracts, records and personnel as may 
reasonably be requested; (b) to deem all information received by 

                                       61
<PAGE>
each party from the other party subject to the confidentiality agreements 
between the parties; (c) to cooperate and prepare the Registration Statement,

the FCC seeking approval of the change of control of Orion; (e) to file all 
documents required under the HSR Act with the FTC and United States 
Department of Justice; (f) to consult with the other party before issuing any 
press releases relating to matters contemplated by the Merger Agreement; (g)

actions and do, or cause to be done, all other things necessary, proper or 
advisable to consummate and make effective, as promptly as practicable, the 
transactions contemplated by the Merger Agreement; (h) that Loral shall cause 
the Surviving Corporation to provide employee benefits to Orion employees 
which are no less favorable, in the aggregate, than those provided by Orion 
on the date of the Merger Agreement; (i) that Loral will use all reasonable 
efforts to cause the shares of Loral Common Stock issuable pursuant to the 
Merger Agreement (including shares issuable upon exercise of the Converted 
Options and Converted Warrants) to be approved for listing on the NYSE, 
subject to official notice of issuance prior to the closing date of the 
Merger; (j) that Loral shall obtain any necessary blue sky permits and 
approvals required to distribute Loral Common Stock; (k) that Orion not less 
than 30 days prior to the Effective Time will deliver to Loral a letter 
identifying all persons who may be deemed to be affiliates of Orion under 
Rule 145 of the Securities Act and will use all reasonable efforts to cause 
each person so identified to deliver to Loral an affiliate agreement with 
respect to Rule 145 under the Securities Act providing that such affiliate 
will not transfer any Loral Common Stock received in the Merger except in 
compliance with the Securities Act; and (l) take all action necessary in 
accordance with applicable law to convene the Stockholders' Meeting.

   Termination by Either Orion or Loral. The Merger Agreement may also be 
terminated by either Orion or Loral at any time prior to the Effective Time 
if (a) the Merger is not consummated by June 30, 1998 (provided that the 
right to terminate the Merger Agreement under such provision will not be 
available to any party whose failure to fulfill any obligation under the

Merger to occur on or before such date); (b) the approval of Orion's 
stockholders required under the Merger Agreement shall not have been obtained

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 
material adverse effect. 

   Termination by Loral. The Merger Agreement may be terminated at any time 
prior to the Effective Time, whether before or after approval of the Merger 
Agreement and the Merger by the stockholders of 

                                       63
<PAGE>
Orion, by Loral if the Board of Directors of Orion or any committee thereof 
shall have withdrawn or modified its approval or recommendation of the Merger 
or the Merger Agreement in any manner adverse to Loral, or approved or 
recommended any acquisition proposal (other than the Merger), or shall have 
resolved to take any of the foregoing actions. 

   Termination by Orion. The Merger Agreement may be terminated at any time

event of the termination of the Merger Agreement as provided above, the 
Merger Agreement shall forthwith become void, there shall be no liability on 
the part of Loral, Merger Subsidiary or Orion or any of their respective 
officers or directors to the other parties to the Merger Agreement and all 
rights and obligations of any party thereto shall cease, except (i) to the

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 the Merger 
Agreement, (ii) that nothing therein shall relieve any party for any breach 
of the Merger Agreement and (iii) that certain provisions relating to 
confidentiality and expenses shall survive termination of the Merger 
Agreement indefinitely. 

   Amendment. The Merger Agreement may be amended by the parties 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 the 
Merger Agreement and the Merger by the stockholders of Orion, no amendment 
may be made which would reduce the amount or change the type of consideration 
into which each share of Orion Capital Stock shall be converted pursuant to 
the Merger Agreement upon consummation of the Merger or which by law 
otherwise requires the further approval of such stockholders. The Merger 
Agreement may not be amended except by an instrument in writing signed by the 
parties to the Merger Agreement. 

 Termination Fee 

   Loral and Orion have agreed that Orion will pay Loral a termination fee of

Orion consummates either (1) a merger, consolidation or other business 
combination between Orion and any other person (other than Loral, Merger 
Subsidiary or an affiliate of Loral) or (2) the sale of 30% or more (in 
voting power) of the voting securities of Orion or of 30% or more (in fair 
market value) of the assets of Orion and its subsidiaries, on a consolidated 
basis, in which case, the Termination Fee must be paid simultaneously with 
the closing of the event described in clause (1) or (2) above. 

 Expenses

Agreement may (a) extend the time for the performance of any of the

the representations and warranties contained in the Merger Agreement or in

of such party. No delay or failure on the part of any party to the Merger 
Agreement in exercising any right, power or privilege thereunder or under any 
instrument or document given in connection with or pursuant to the Merger 
Agreement shall impair any right, power or privilege or be construed as a 
waiver of any default or any acquiescence therein. No single or partial 
exercise of any 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. 

THE PRINCIPAL STOCKHOLDER AGREEMENT 

 General 

   As an inducement and condition to Loral's willingness to enter into the 
Merger Agreement, Orion, certain principal stockholders of Orion consisting 
of certain members of Orion's Board of Directors and their affiliated 
companies (the "Principal Stockholders"), Loral and Merger Subsidiary entered 
into the Principal Stockholder Agreement on October 7, 1997, which covers an 
aggregate of approximately 32% of the Orion voting stock as of February 12, 
1998, as well as shares of Orion Common Stock into which certain Debentures 
may be converted in accordance with the provisions of the Principal 
Stockholder Agreement (collectively with other shares that have or will 
become subject thereto, the "Covered Shares"). The Principal Stockholder 
Agreement was amended and restated as of December 1, 1997 to make certain 
technical corrections. 

 Agreement to Vote 

   Pursuant to the Principal Stockholder Agreement, each of the Principal 
Stockholders has agreed at any meeting of Orion's stockholders, however 
called, and in any action by consent of the stockholders of Orion, to vote 
his or her Covered Shares from the date of the Principal Stockholder 
Agreement to the earliest to occur of the termination of the Merger Agreement 
or the Effective Time, (i) in favor of the Merger, the Merger Agreement (as 
amended from time to time) and the transaction contemplated by the Merger 
Agreement (collectively, the "subject transactions"), (ii) against any 
proposal for any recapitalization, merger (other than the Merger), sale of 
assets or other business combination between Orion and any person or entity 
(other than Loral or Merger Subsidiary) or any other action or agreement that 
would result in a breach of any covenant or any other obligation or agreement 
of Orion 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 the Principal 
Stockholder Agreement or the Merger Agreement): (A) any extraordinary 
corporate transaction, such as a merger, consolidation or other business 
combination involving Orion or any of its subsidiaries; (B) any sale, lease 
or transfer by Orion of a material amount of assets (including stock) of 
Orion or any of its subsidiaries; or a reorganization, restructuring, 
recapitalization, special dividend, dissolution or liquidation of Orion or 
any of its subsidiaries; or (C)(1) any change in a majority of the persons 
who constitute the Board of Directors of Orion or any of its subsidiaries; 
(2) any change in the present capitalization of Orion or any of its 
subsidiaries including any proposal to sell a substantial equity interest in 
Orion or any of its subsidiaries; (3) any amendment to Orion or any of its 
subsidiaries' charters or bylaws; (4) any other change in Orion or any of its 
subsidiaries' corporate structure or business; or (5) any other action which, 
in the case of each of the matters referred to in clauses (C)(1), (2), (3) or 
(4), is intended, or could reasonably be expected, to impede, interfere with, 
delay, postpone, or materially adversely affect the Merger and the 
transactions contemplated by the Principal Stockholder Agreement. 

   With respect to each of its Covered Shares, from the date of the Principal 
Stockholder Agreement to the earliest to occur of the termination of the 
Merger Agreement or the Effective Time, each of the Principal Stockholders 
has appointed Loral and Merger Subsidiary to be its lawful attorney and 
proxy, for 

                                       65
<PAGE>
and in its name place and stead, to vote each of its Covered Shares as its 
proxy at every annual, special or adjourned meeting of the stockholders of 
Orion, including the right to sign its name to any consent, certificate or 
other document relating to Orion that the law of the State of Delaware may 
permit or require in each of the situations described in (i) to (iii) in the 
preceding paragraph. This power of attorney is irrevocable. 

   Each Principal Stockholder has agreed that it will not enter into any 
agreement or understanding the effect of which would be inconsistent with or 
violative of the provisions and agreements contained in the Principal 
Stockholder Agreement. Further, each Principal Stockholder has agreed that it 
will, if the Board of Directors of Orion fails or refuses (other than as a 
result of breach by Loral or any of its affiliates of the Merger Agreement or 
because the Loral and its affiliates will not or cannot satisfy the 
conditions precedent thereto) to submit the subject transactions to Orion's 
stockholders, vote all Covered Shares held of record or beneficially owned by 
it to (i) call or cause to be called a special meeting of stockholders of 
Orion (or effect a written consent) to remove the directors of Orion who have 
so failed or refused, or to increase the size of the Board of Directors and 
elect a majority of new directors who will submit the subject transactions to 
the stockholders of Orion for a vote, and (ii) use its reasonable efforts to 
effect such removal and replacement, or increase and election, and the 
submission of the subject transactions to the stockholders of Orion; and 
(iii) at any time after initial approval by the stockholders of Orion of the 
subject transactions, if so requested by Loral, to approve all or any actions 
incident to the subject transactions or certain other matters described in 
the Principal Stockholder Agreement by stockholder written consent. If there 
is an Exchange Offer (as defined above), each Principal Stockholder has 
agreed to tender his or her Covered Shares into the Exchange Offer. 

 Grant of Loral Option 

   Pursuant to the Principal Stockholder Agreement, the Principal 
Stockholders granted Loral an irrevocable option to purchase all (but not 
less than all) of the Covered Shares in certain circumstances (the "Loral 
Option"). The option exercise price is equal to the number of Covered Shares 
to be purchased by Loral multiplied by the Exchange Ratio (calculated using 
the date Loral gives notice of exercise of the option as if it were the 
closing date of the Merger for purposes of determining the Determination 
Price) together with the associated rights under Loral's Rights Plan dated as 
of March 27, 1996 between Loral and the Bank of New York, as Right Agent. The 
shares of Orion Common Stock or Debentures subject to the Loral Option are 
held by BAe, W. Neil Bauer, Orion's President and Chief Executive Officer, 
Fleet Venture Resources, Inc., Fleet Equity Partners, VI L.P., Chisholm 
Partners, II, L.P. and the following members of the Orion Board of Directors: 
John V. Saeman, Gustave M. Hauser, Sidney S. Kahn and John G. Puente. 

   The Loral Option will become exercisable in whole (but not in part) upon 
the occurrence of specified events or transactions, which are listed below 
(each, a "Purchase Event"). If Loral exercises the Loral Option, Loral and 
Merger Subsidiary have agreed to use their reasonable best efforts to 
consummate the Merger (or the Exchange Offer as applicable) as promptly as 
practicable, except to the extent that consummation of the Merger would 
violate applicable law. 

   A Purchase Event under the Loral Option means any of the following events 
or transactions: 

   (a) the Board of Directors of Orion or any committee thereof shall have 
withdrawn or modified its approval or recommendation of the Merger or the 
Merger Agreement in any manner adverse to Loral, or approved or recommended 
any acquisition proposal, or shall have adopted a resolution to take any of 
the foregoing actions; 

   (b) (i) the approval of the Merger Agreement by the stockholders of Orion 
shall have not been obtained by reason of the failure to obtain the required 
vote at the Special Meeting and (ii) at the time of such negative vote there 
shall be pending an acquisition proposal; 

   (c) Orion or any of its subsidiaries shall have entered into any agreement 
with any person (other than Loral or any of its affiliates), the Board of 
Directors of such entity shall have approved, recommended or resolved to 
enter into an agreement with any person, or Orion shall have publicly 
announced its intention 

                                       66
<PAGE>
to take any of the foregoing actions, with respect to the sale of 20% or more 
(in voting power) of the voting securities of Orion or of 20% or more (in 
fair market value) of the assets of Orion and its subsidiaries, on a 
consolidated basis, however such transaction may be effected; or 

   (d) any person (other than Loral or any of its affiliates), shall have 
commenced (as such term is defined in Rule 14d-2 under the Exchange Act) or 
shall have filed a registration statement under the Exchange Act, with 
respect to a tender or exchange offer for securities representing 35% or more 
of the voting power of Orion; or the acquisition, by any person or group (as 
defined in Section 13(d) of the Exchange Act), other than Loral or any of its 
affiliates, of beneficial ownership of (as defined in the Rule 13d-3 under 
the Exchange Act), or the right to acquire beneficial ownership of, 
securities representing 35% or more of the voting power of Orion. 

   The Loral Option will terminate upon the earliest to occur of the (i) 
Effective Time, (ii) June 30, 1998 or (iii) termination of the Merger 
Agreement by Loral or Merger Subsidiary in accordance with the terms thereof. 

   In the event that Loral exercises the Loral Option, as promptly as 
practicable following the closing date for the Exchange Offer (but not more 
than 60 days following the closing date thereof), Loral shall (i) file a 
shelf registration statement covering all shares of Loral Common Stock for 
the purposes of resale of shares of Loral Common Stock by each Principal 
Stockholder and (ii) use its reasonable best efforts to cause such shelf 
registration statement to become and remain effective for the resale of all 
shares of Loral Common Stock issued pursuant to the Principal Stockholder 
Agreement. 

   The consummation of a purchase or sale pursuant to the Principal 
Stockholder Agreement is subject to, among other things, the registration of 
the shares of Loral Common Stock to be issued upon Loral Option exercise and 
obtaining any required regulatory approvals. In the event that prior 
notification to or approval of any regulatory authority is required in 
connection with such purchase or sale, Loral and, if applicable, a Principal 
Stockholder will promptly file the required notice or application for 
approval and will expeditiously process the same (and such Principal 
Stockholder will cooperate with Loral in the filing of any such notice or 
application and the obtaining of any such approval). 

 Adjustment of Number of Shares Subject to Option 

   If on or after the date of the Principal Stockholder Agreement there 
occurs any stock dividend, stock split, recapitalization, combination or 
exchange of shares, merger, consolidation, reorganization or other change or 
transaction of or by Orion, as a result of which shares of any class of 
stock, other securities, cash or other property will be issued in respect of 
any Covered Shares or if any Covered Shares shall be changed in the same or 
another class of stock or other securities, then, upon exercise of the Loral 
Option, Loral will receive for the aggregate price payable upon exercise of 
the Loral Option, all such shares of stock, other securities, cash or other 
property issued, delivered or received with respect to such Covered Shares. 

   If on or after the date of the Principal Stockholder Agreement there 
occurs any stock dividend, stock split, recapitalization, combination or 
exchange of shares, merger, consolidation, reorganization or other change or 
transaction of or by Loral, as a result of which shares of any class of 
stock, other securities, cash or other property will be issued in respect of 
any Loral Common Stock or if any Loral Common Stock shall be changed in the 
same or another class of stock or other securities, then, upon exercise of 
the Loral Option, each Principal Stockholder will receive for the aggregate 
price payable to such Principal Stockholder upon exercise of the Loral 
Option, all such shares of stock, other securities, cash or other property 
issued, delivered or received with respect to such Loral Common Stock to be 
delivered to such Principal Stockholder. 

  Agreement Not to Transfer 

   Pursuant to the Principal Stockholder Agreement, each Principal 
Stockholder has agreed that, from the date of the Principal Stockholder 
Agreement to the termination of the rights of Loral under the Principal 
Stockholder Agreement, it shall not sell, transfer, tender, assign, 
hypothecate or otherwise dispose of, or create or permit to exist any 
encumbrance on the Covered Shares owned by such Principal 

                                       67
<PAGE>
Stockholder at any time prior to the Effective Time. However, each Principal 
Stockholder may transfer Covered Shares to (a) any member of such Principal 
Stockholder's immediate family, (b) any trust or similar instrument for 
estate planning purposes or (c) any charitable organization, foundation or 
similar entities. Such transfer, however, may be made to any such permitted 
transferee only if such permitted transferee agrees in writing to all of the 
terms, conditions and restrictions set forth in the Principal Stockholder 
Agreement regarding Covered Shares received by such permitted transferee. 

 Debentures Conversion 

   Pursuant to the Principal Stockholder Agreement, BAe has agreed that all 
the Debentures it holds will be converted into shares of Orion Common Stock 
(together with any shares of Orion Common Stock representing accrued but 
unpaid interest on the Debentures) in accordance with the terms of the 
debenture purchase agreement relating thereto immediately prior to the 
Effective Time (except if converted prior to such date), and at such time, 
converted into the right to receive in the Merger Loral Common Stock in 
accordance with the Merger Agreement. 

 Transfer of Loral Common Stock by British Aerospace 

   BAe and Loral have agreed to consult and cooperate with respect to the 
orderly disposition of the Loral shares obtained by BAe. BAe has agreed that 
for a period of twelve months from the date it acquires Loral shares it will 
not and will cause each of its affiliates not to, sell or otherwise transfer 
any Loral shares other than by means of 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 will consult with Loral prior to such sale and seek 
the consent of Loral to such sale, which consent shall not be unreasonably 
withheld, conditioned or delayed. As an alternative to conducting block 
trades, BAe shall have the right to sell all (but not less than all) of its 
Loral shares pursuant to an underwritten sale with an underwriter reasonably 
acceptable to Loral. 

 Control Shares 

   Pursuant to the Principal Stockholder Agreement, Orion has agreed to waive 
its rights under Article ELEVENTH, Section H, of its Restated Certificate of 
Incorporation with respect to all Covered Shares acquired pursuant to 
exercise of the Loral Option, and has agreed, promptly following any such 
exercise, to exchange for such Covered Shares an equal number of duly 
authorized, but unissued shares of Orion Common Stock, which upon issuance 
will be validly issued, fully paid and nonassessable shares, and which will 
not be "control shares" within the meaning of such Article ELEVENTH. 

 Possible Amendment 

   Orion and Loral are currently contemplating an amendment to the Principal 
Stockholder Agree-ment that would permit BAe to convert its Debentures into 
3,571,429 shares of Orion Common Stock and sell such shares prior to the 
Effective Date of the Merger. In addition, SS/L is contemplating the sale of 
the 588,235 shares of Orion Common Stock it owns prior to Effective Date of 
the Merger. Any such sales would take place following the Record Date, and 
the right to direct the voting of such shares would not be transferred.

       Lockheed Martin. The Distribution of approximately 183.6 million shares 
       of Loral Common Stock was made on April 23, 1996. Old Loral's fiscal 
       year end was March 31. Loral adopted a December 31 year end and its 
       first fiscal quarter ended on June 30, 1996. Accordingly, data reflects

   On January 4, 1997, Orion entered into a Capacity Services Agreement with 
AT&T Skynet (now Loral Skynet), as amended on July 23, 1997, whereby Orion 
provided to AT&T Skynet 54 MHz of capacity on the Orion 1 satellite for a 
term of nine (9) months for aggregate fees of approximately $810,000. This 
agreement terminated in September 1997.

as of September 30, 1997. 

LORAL COMMON STOCK 

   The holders of Loral Common Stock are entitled to voting rights. Under 
Bermuda Law, questions brought before a general meeting of shareholders are 
decided by a majority vote of shareholders present at the meeting (or by such 
majority as The Companies Act 1981 of Bermuda (the "Bermuda Law") or Loral's 
Bye-Laws (as defined below) prescribe). Loral's Bye-Laws provide that, with 
certain exceptions, any questions proposed for the consideration of the 
shareholders will be decided by a simple majority of votes cast by 
shareholders entitled to vote at the meeting, with each shareholder present, 
or person holding proxies for any shareholder, entitled to one vote for each 
share held. 

   The holders of Loral Common Stock are entitled to receive ratably the 
dividends, if any, that may be declared from time to time by the Board of 
Directors out of funds legally available for such dividends. The holders of 
Loral Common Stock are entitled, under certain circumstances, to share 
ratably with holders of the Loral Series A Preferred Stock in all assets 
remaining after payment of liabilities and after provision has been made for 
the payment of the $.01 liquidation preference on the Loral Series A 
Preferred Stock and the liquidation preference on any other series of 
preferred stock of Loral. Holders of Loral Common Stock have no preemptive 
rights and no right to convert their Loral Common Stock into any other 
securities. There are no redemption or sinking fund provisions applicable to 
the Loral Common Stock. All the outstanding shares of Loral Common Stock are 
validly issued, fully paid and nonassessable. 

LORAL PREFERRED STOCK 

   Loral Series A Preferred Stock. The holders of Loral Series A Preferred 
Stock are entitled to vote together with the holders of Loral Common Stock as 
a single class on all matters submitted to shareholders, except that the 
holders of Loral Series A Preferred Stock may not vote with respect to the 
election of directors of Loral. The Loral Series A Preferred Stock is 
entitled to a liquidation preference of $.01 per share and otherwise 
participates pro rata with the Loral Common Stock in dividends and 
distributions, subject under certain circumstances to priority rights over 
the Loral Common Stock and pro rata distribution rights with the most senior 
preferred stock of Loral then outstanding in a liquidating distribution. The 
Loral Series A Preferred Stock is subject to certain antidilution 
adjustments, including adjustments for stock splits and reclassifications. 
The Loral Series A Preferred Stock will be convertible into Loral Common 
Stock at the option of the holder upon receipt of certain antitrust 
clearances or upon a sale to a third party unaffiliated with Lockheed Martin. 

                                       71
<PAGE>
   Loral Series B Preferred Stock. The Loral Series B Preferred Stock will, 
if issued, be junior to any other series of preferred stock which may be 
authorized by Loral's shareholders. Holders of the Rights will be entitled, 
subject to the occurrence of certain events, to purchase from Loral, one 
one-thousandth of a share of Loral Series B Preferred Stock at a purchase 
price of $50, but before such purchase will have no voting, conversion, 
redemption or preemptive rights, nor will they have any right to receive 
dividends. 

   Loral Series C Preferred Stock. The Loral Series C Preferred Stock, with 
respect to dividend rights and rights upon liquidation, winding up and 
dissolution, ranks pari passu with the Loral Series A Preferred Stock and 
senior to or pari passu with all other existing and future series of 
preferred stock of Loral and senior to the Loral Common Stock. 

TRANSFER AGENT AND REGISTRAR 

   The Transfer Agent and Registrar for Loral Common Stock is The Bank of New 
York. 

CERTAIN ANTITAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE BYE-LAWS 

   Loral's Bye-Laws contain certain provisions that could make more difficult 
the acquisition of Loral by means of a tender offer, a proxy contest or 
otherwise. 

CLASSIFIED BOARD OF DIRECTORS; ELECTION AND REMOVAL OF DIRECTORS 

   Loral's Bye-Laws provide that the Board will be divided into three classes 
of directors, with the classes to be as nearly equal in number as possible. 

   The classification of directors will have the effect of making it more 
difficult for shareholders to change the composition of the Board. At least 
two annual meetings of shareholders, instead of one, will generally be 
required to effect a change in a majority of the Board. Such a delay may help 
ensure that Loral's directors, if confronted by a holder attempting to force 
a proxy contest, a tender or exchange offer, or an extraordinary corporate 
transaction, would have sufficient time to review the proposal as well as any 
available alternatives to the proposal and to act in what they believe to be 
the best interest of the shareholders. The classification provisions will 
apply to every election of directors, regardless of whether a change in the 
composition of the Board would be beneficial to Loral and its shareholders 
and whether or not a majority of Loral's shareholders believe that such a 
change would be desirable. 

   The classification provisions could also have the effect of discouraging a 
third party from initiating a proxy contest, making a tender offer or 
otherwise attempting to obtain control of Loral, even though such an attempt 
might be beneficial to Loral and its shareholders. The classification of the 
Board could thus increase the likelihood that incumbent directors will retain 
their positions. In addition, because the classification provisions may 
discourage accumulations of large blocks of Loral's stock by purchasers whose 
objective is to take control of Loral and remove a majority of the Board, the 
classification of the Board could tend to reduce the likelihood of 
fluctuations in the market price of Loral Common Stock that might result from 
accumulations of large blocks for such a purpose. Accordingly, shareholders 
could be deprived of certain opportunities to sell their shares of Loral 
Common Stock at a higher market price than might otherwise be the case. 

   Loral's Bye-Laws provide that, unless recommended by the directors, no 
person other than a director whose term is expiring at an annual general 
meeting shall be eligible for election to the office of director at any 
annual general meeting. Directors may only be removed by the shareholders, at 
a special general meeting specifically called for that purpose, for cause and 
only upon the affirmative vote of shareholders holding at least 80% of the 
shares issued and outstanding and entitled to vote at the annual general 
meetings. 

NO SHAREHOLDER ACTION BY CONSENT; SPECIAL MEETINGS 

   Loral's Bye-Laws provide that shareholder action can be taken only at an 
annual or special meeting of shareholders and prohibit shareholder action by 
written consent in lieu of a meeting. The business permitted to be conducted 
at any special meeting of shareholders is limited to the business brought 
before the meeting pursuant to the notice of meeting given by Loral. 

                                       72
<PAGE>
   The provisions of Loral's Bye-Laws prohibiting shareholder action by 
written consent may have the effect of delaying consideration of a 
shareholder proposal until the next annual meeting unless a special meeting 
is called by the Board at the request of a majority of the directors or a 
shareholder holding at least 10% of the total voting rights. These provisions 
would also prevent the holders of a majority of the shares issued and 
outstanding and entitled to vote from unilaterally using the written consent 
procedure to take shareholder action and from taking action by consent. 

ADVANCE NOTICE PROVISIONS FOR SHAREHOLDER NOMINATIONS AND SHAREHOLDER 
PROPOSALS 

   Loral's Bye-Laws establish an advance notice procedure for shareholders to 
make nominations of candidates for election as directors, or bring other 
business before an annual meeting of shareholders of Loral (the "Shareholder 
Notice Procedure"). 

   The Shareholder Notice Procedure provides that only persons who are 
nominated by, or at the direction of, the Board, any number of shareholders 
holding at least 5% of the total voting rights of all shareholders or not 
less than 100 shareholders who have given timely written notice to the 
Secretary of Loral prior to the meeting at which directors are to be elected, 
will be eligible for election as directors of Loral. The Shareholder Notice 
Procedure provides that at an annual meeting only such business may be 
conducted as has been brought before the meeting by, or at the direction of, 
the Chairman of the Board or by shareholders who have given timely written 
notice to the Secretary of Loral of such shareholders' intention to bring 
such business before such meeting. Under the Shareholder Notice Procedure, 
for a notice of shareholder nominations to be made at an annual meeting to be 
timely, such notice must be received by Loral not less than 6 weeks nor more 
than 10 weeks prior to the first anniversary of the previous year's annual 
meeting. 

   Under the Shareholder Notice Procedure, a shareholder's notice to Loral 
proposing to nominate a person for election as a director must contain 
information, including, without limitation, the identity and address of the 
nominating shareholder, the class and number of shares of stock of Loral 
which are owned by such shareholder, and all information regarding the 
proposed nominee that would be required to be included in a proxy statement 
soliciting proxies for the proposed nominee. Under the Shareholder Notice 
Procedure, a shareholder's notice relating to the conduct of business other 
than the nomination of directors must contain certain information about such 
business and about the proposing shareholder including, without limitation, a 
brief description of the business such shareholder proposes to bring before 
the meeting, the reasons for conducting such business at such meeting, the 
name and address of such shareholder, the class and number of shares of stock 
of Loral beneficially owned by such shareholder, and any material interest of 
such shareholder in the business so proposed. If the Chairman of the Board or 
other officer presiding at a meeting determines that a person was not 
nominated, or other business was not brought before the meeting, in 
accordance with the Shareholder Notice Procedure, such person will not be 
eligible for election as a director, or such business will not be conducted 
at such meeting, as the case may be. 

   By requiring advance notice of nominations by shareholders, the 
Shareholder Notice Procedure will afford the Board an opportunity to consider 
the qualifications of the proposed nominees and, to the extent deemed 
necessary or desirable by the Board, to inform shareholders about such 
qualifications. By requiring advance notice of other proposed business, the 
Shareholder Notice Procedure will also provide a more orderly procedure for 
conducting annual meetings of shareholders and, to the extent deemed 
necessary or desirable by the Board, will provide the Board with an 
opportunity to inform shareholders, prior to such meetings, of any business 
proposed to be conducted at such meetings, together with any recommendations 
as to the Board's position regarding action to be taken with respect to such 
business, so that shareholders can better decide whether to attend such a 
meeting or to grant a proxy regarding the disposition of any such business. 

   Loral's Bye-Laws may have the effect of reducing the shareholders' ability 
to engage a contest for the election of directors or the consideration of 
shareholder proposals if the proper procedures are not followed, and of 
discouraging or deterring a third party from conducting a solicitation of 
proxies to elect its own slate of directors or to approve its own proposal, 
without regard to whether considerations of such nominees or proposals might 
be harmful or beneficial to Loral and its shareholders.

VOTING REQUIREMENT FOR CERTAIN BUSINESS COMBINATIONS 

   Loral's Bye-Laws also provide that, in addition to any affirmative vote 
required by law, the affirmative vote of holders of not less than 80% of the 
shares carrying voting rights of Loral shall be necessary to approve any 
"Business Combination" (as defined below) proposed by an "Interested 
Shareholder" (as defined below). The additional voting requirements will not 
apply, however, if: (i) the Business Combination was approved by not less 
than a majority of the Continuing Directors (as defined below) or (ii) a 
series of conditions are satisfied requiring (in summary) (a) that the 
consideration to be paid to Loral's shareholders in the Business Combination 
must be at least equal to the higher of (x) the highest per-share price paid 
by the Interested Shareholder in acquiring any shares of Loral Common Stock 
during the two years prior to the announcement date of the Business 
Combination or in the transaction in which it became an Interested 
Shareholder (the "Determination Date"), whichever is higher or (y) the fair 
market value per share of Loral Common Stock on the announcement date or 
Determination Date, whichever is higher, in either case appropriately 
adjusted for any stock dividend, stock split, combination of shares or 
similar event (any non-cash consideration is treated similarly) and (b) 
certain "procedural" requirements are complied with, such as the solicitation 
of proxies pursuant to the rules of the Commission and no decrease in regular 
dividends (if any) after the Interested Shareholder became an Interested 
Shareholder (except as approved by a majority of the Continuing Directors). 

   An "Interested Shareholder" is defined as anyone who is the beneficial 
owner of more than 15% of shares carrying voting rights, other than Loral and 
any employee stock plans sponsored by Loral, and includes any person who is 
an assignee of, or has succeeded to any shares of voting stock in a 
transaction not involving a public offering that were at any time within the 
prior two-year period beneficially owned by, an Interested Shareholder. The 
term "beneficial owner" includes persons directly and indirectly owning or 
having the right to acquire or vote the stock. Interested Shareholders 
participate fully in all shareholder voting. 

   A "Business Combination" includes the following transactions: (a) merger 
or consolidation of Loral or any subsidiary with an Interested Shareholder or 
with any other corporation or entity which is, or after such merger or 
consolidation would be, an affiliate of an Interested Shareholder, (b) the 
sale or other disposition by Loral or a subsidiary of assets having a fair 
market value of $5,000,000 or more if an Interested Shareholder (or an 
affiliate thereof) is a party to the transaction; (c) the adoption of any 
plan or proposal for the liquidation or dissolution of Loral proposed by or 
on behalf of an Interested Shareholder (or an affiliate thereof); or (d) any 
reclassification of securities, recapitalization, merger with a subsidiary, 
or other transaction which has the effect, directly or indirectly, of 
increasing the proportionate share of any class of the outstanding stock (or 
securities convertible into stock) of Loral or a subsidiary owned by an 
Interested Shareholder (or an affiliate thereof). Determinations of the fair 
market value of any non-cash consideration are made by a majority of the 
Continuing Directors. 

   As used in Loral's Bye-Laws, the term "Continuing Directors" means any 
member of the Board of Directors of Loral, while such person is a member of 
the Board, who is not an affiliate or associate or representative of the 
Interested Shareholder and was a member of the Board prior to the time that 
the Interested Shareholder became an Interested Shareholder, and any 
successor of a Continuing Director while such successors is a member of the 
Board, who is not an affiliate or associate or representative of the 
Interested Shareholder and is recommended or elected to succeed the 
Continuing Director by a majority of Shareholder Continuing Directors. 

AMENDMENT OF CERTAIN PROVISIONS OF THE BYE-LAWS 

   Loral's Bye-Laws provide that the vote of shareholders holding at least 
80% of the shares issued and outstanding and entitled to vote, is required to 
amend provisions of Loral's Bye-Laws relating to the prohibition of 
shareholder action without a meeting; the number, election and term of 
Loral's directors; the removal of directors; or approval of Business 
Combinations. The vote of shareholders holding not less than a majority of 
the shares issued and outstanding and entitled to vote is required to amend 
all other provisions of Loral's Bye-Laws. The 80% voting requirement will 
have the effect of making more difficult any amendment by shareholders of 
Loral's Bye-Laws described above, even if a majority of Loral's shareholders 
believe that such amendment would be in their best interests. 

                                       74
<PAGE>
LORAL'S RIGHTS PLAN 

   The following is a description of the Rights Plan (the "Rights Plan") 
which Loral has adopted and has entered into a Rights Agreement dated March 
27, 1996 between Loral and The Bank of New York, as Rights Agent (the "Rights 
Agreement"): 

   The Rights Plan provides that one Right will be issued for each share of 
Loral Common Stock outstanding at the close of business on a date to be set 
by the Board of Directors (the "Rights Record Date") and with respect to the 
Loral Common Stock issued thereafter until the Rights Separation Date (as 
defined below) and in certain circumstances, with respect to the Loral Common 
Stock issued after the Rights Separation Date. Except as set forth below each 
Right, when it becomes exercisable, entitles the registered holder thereof to 
purchase from Loral a unit consisting initially of one one-thousandth of a 
share (a "Unit") of Series B Preferred Stock, par value $.01 per share, at a 
purchase price of $50 per Unit, subject to adjustment (the "Purchase Price"). 

   Initially, the Rights will attach to all certificates representing shares 
of Loral Common Stock then outstanding, and no separate certificates 
evidencing the Rights (the "Rights Certificate") will be distributed. The 
Rights will separate from the Loral Common Stock and a "Rights Separation 
Date" will occur upon the earlier of (i) ten days (or such later date as 
Loral's Board of Directors shall determine with the concurrence of a majority 
of the Continuing Directors) following public disclosure that a person or 
group of affiliated or associated persons has become an "Acquiring Person" 
(as defined below) or (ii) ten business days (or such later date as Loral's 
Board of Directors shall determine with the concurrence of a majority of the 
Continuing Directors) following the commencement of a tender offer or 
exchange offer that would result in a person or group becoming an "Acquiring 
Person." Except as set forth below, an "Acquiring Person" is a person or 
group of affiliated or associated persons who has acquired beneficial 
ownership of 15% or more of the outstanding shares of Loral Common Stock 
except that Loral and its affiliates and associates will not be deemed to be 
an "Acquiring Person" until such time as Loral and its affiliates and 
associates become the beneficial owner of 25% or more of the outstanding 
shares of Loral Common Stock. The term "Acquiring Person" excludes (i) Loral, 
(ii) any subsidiary of Loral, (iii) any employee benefit plan of Loral or any 
subsidiary of Loral or (iv) any person, or entity organized, appointed or 
established by Loral for or pursuant to the terms of any such plan. A 
"Continuing Director" is a member of the Board of Directors who is not an 
Acquiring Person, an affiliate or associate of an Acquiring Person or a 
representative or nominee of an Acquiring Person. 

   Until the occurrence of the Rights Separation Date, (i) the Rights will be 
evidenced by the Loral Common Stock certificates and would be transferred 
with and only with such Loral Common Stock certificates, (ii) new Loral 
Common Stock certificates issued after the Rights Record Date will contain a 
notation incorporating the Rights Agreement by reference, and (iii) the 
surrender for transfer of any certificates for Loral Common Stock outstanding 
will also constitute the transfer of the Rights associated with the Loral 
Common Stock represented by such certificate. Pursuant to the Rights 
Agreement, Loral reserves the right to require prior to the occurrence of a 
Triggering Event (as defined below) that, upon any exercise of Rights, a 
number of Rights be exercised so that only whole shares of the Loral Series B 
Preferred Stock will be issued. 

   As soon as practicable after the occurrence of the Rights Separation Date, 
Rights Certificates will be mailed to holders of record of Loral Common Stock 
as of the close of business on the Rights Separation Date and, thereafter, 
the separate Rights Certificates alone will represent the Rights. Except in 
certain circumstances specified in the Rights Agreement or as otherwise 
determined by the Board of Directors of Loral, only shares of the Loral 
Common Stock issued prior to the Rights Separation Date will be issued with 
Rights. 

   The Rights will not be exercisable until the occurrence of the Rights 
Separation Date. The Rights will expire at the close of business on a date 
ten years after the Rights Record Date unless extended or earlier redeemed by 
Loral as described below. 

   In the event that, at any time following the Rights Separation Date, a 
person becomes an Acquiring Person (except pursuant to an offer for all 
outstanding shares of Loral Common Stock at a price and on 

                                       75
<PAGE>
terms which a majority of each of the Continuing Directors and independent 
directors determine to be fair to and otherwise in the best interests of 
Loral and its shareholders), each holder of a Right would thereafter have the 
right to receive, upon exercise of the Right, Loral Common Stock (or, in 
certain circumstances, cash, property or other securities of Loral) having a 
value equal to two times the exercise price of the Right. Notwithstanding the 
foregoing, following the occurrence of the event set forth above, all Rights 
that are, or (under certain circumstances specified in the Rights Agreement) 
were, beneficially owned by any Acquiring Person will be null and void and 
nontransferable and any holder of any such Right (including any purported 
transferee or subsequent holder) will be unable to exercise or transfer any 
such Right. For example, at an exercise price of $50 per Right, each Right 
not owned by an Acquiring Person (or by certain related parties) following an 
event set forth in this paragraph would entitle its holder to purchase $100 
worth of Loral Common Stock (or other consideration, as noted above) for $50. 
Assuming that the Loral Common Stock had a per share value of $25 at such 
time, the holder of each valid Right would be entitled to purchase four 
shares of Loral Common Stock for $50. 

   In the event that, at any time following the date on which there has been 
public disclosure that, or of facts indicating that, a person has become an 
Acquiring Person (the "Stock Acquisition Date"), (i) Loral is acquired in a 
merger or other business combination transaction in which Loral is not the 
surviving corporation (other than a merger which follows an offer described 
in the preceding paragraph or a merger with Globalstar Telecommunications 
Limited ("GTL")), or (ii) 50% or more of Loral's assets or earnings power is 
sold, mortgaged or transferred, each holder of a Right (except Rights which 
previously have been voided as set forth above) will thereafter have the 
right to receive, upon exercise, common stock of the acquiring company having 
a value equal to two times the exercise price of the Right. The events set 
forth in this paragraph and in the preceding paragraph are referred to as the 
"Triggering Events." 

   The Purchase Price payable, and the number of Units of Series B Preferred 
Stock or other securities or property issuable, upon exercise of the Rights 
are subject to adjustment from time to time to prevent dilution (i) in the 
event of a stock dividend on, or a subdivision, combination or 
reclassification of, the Loral Series B Preferred Stock, (ii) if holders of 
Series B Preferred Stock are granted certain rights or warrants to subscribe 
for Series B Preferred Stock or convertible securities at less than the 
current market price of the Loral Series B Preferred Stock, or (iii) upon 
distribution to holders of the Loral Series B Preferred Stock of evidences of 
indebtedness or assets (excluding regular quarterly cash dividends) or of 
subscription rights or warrants (other than those referred to above). 

   With certain exceptions, no adjustment in the Rights Purchase Price will 
be required until cumulative adjustments amount to at least 1% of the Rights 
Purchase Price. No fractional Units will be issued and, in lieu thereof, an 
adjustment in cash will be made based on the market price of the Loral Series 
B Preferred Stock on the last trading date prior to the date of exercise. 

   Because of the nature of the Loral Series B Preferred Stock's dividend and 
liquidation rights, the value of the one one-thousandth interest in a share 
of the Loral Series B Preferred Stock purchasable upon exercise of each Right 
should approximate the value of one share of Common Stock. Securities of 
Series B Preferred Stock purchasable upon exercise of the Rights will not be 
redeemable. Each share of Series B Preferred Stock will be entitled to a 
quarterly dividend payment of 1,000 times the dividend declared per share of 
Common Stock. In the event of liquidation, each share of Series B Preferred 
Stock will be entitled to a $1.00 preference and, thereafter, the holders of 
the shares of Series B Preferred Stock will be entitled to an aggregate 
payment of 1,000 times the aggregate payment made per share of Common Stock. 
Each share of Series B Preferred Stock will have 1,000 times the vote of a 
share of Loral Common Stock, voting together with the shares of Loral Common 
Stock. These rights are protected by customary antidilution provisions. 

   At any time until ten days (or such later date as determined by action of 
the Board of Directors with the concurrence of a majority of the Continuing 
Directors) following the Stock Acquisition Date, Loral may redeem the Rights 
in whole, but not in part, at a price (the "Redemption Price") of $.0001 per 
Right (payable in cash, Loral Common Stock or other consideration deemed 
appropriate by Loral's Board of Directors) by resolution of Loral's Board of 
Directors. The redemption of the Rights may be made 

                                       76
<PAGE>
effective at such time, on such basis, and with such conditions as the Board 
of Directors in its sole discretion may establish. Immediately upon such 
action of the Board of Directors ordering redemption of the Rights, the 
Rights will terminate and the only right of the holders of Rights will be to 
receive the Redemption Price. 

   Until a Right is exercised, the holder thereof, as such, will have no 
rights as a shareholder of Loral including, without limitation, the right to 
vote or to receive dividends. While the distribution of the Rights will not 
be taxable to shareholders or to Loral, shareholders may, depending upon the 
circumstances, recognize taxable income in the event that the Rights become 
exercisable for Loral Common Stock (or other consideration) or for common 
stock of the acquiring company as set forth above. 

   Other than those provisions relating to the principal economic terms of 
the Rights, any of the provisions of the Rights Agreement may be amended by 
resolution of Loral's Board of Directors. After the Rights Separation Date, 
the provisions of the Rights Agreement may be amended by resolution of 
Loral's Board of Directors (with the concurrence of a majority of the 
Continuing Directors, if adopted following the Stock Acquisition Date) in 
order to cure any ambiguity, to make changes which do not adversely affect 
the interests of holders of Rights (excluding the interests of any Acquiring 
Person or its affiliates or associates), or to shorten or lengthen any time 
period under the Rights Agreement; provided, however, that no amendment to 
adjust the time period governing redemption shall be made at such time as the 
Rights are not redeemable. 

   The Rights will have certain antitakeover effects as they will cause 
substantial dilution to a person or group that acquires a substantial 
interest in Loral without the prior approval of the Board of Directors of 
Loral. The effect of the Rights may be to inhibit a change in control of 
Loral (including through a third party tender offer at a price which reflects 
a premium to then prevailing trading prices) that may be beneficial to 
Loral's shareholders. 

 COMPARATIVE RIGHTS OF ORION STOCKHOLDERS AND LORAL STOCKHOLDERS 

   The following discussion (so far as it relates to matters of the laws of 
Bermuda) is based upon the advice of Appleby, Spurling & Kempe, Bermuda 
counsel for Loral. 

   Loral was incorporated on January 12, 1996 as an exempted company under 
the laws of Bermuda. The rights of its shareholders are governed by Bermuda 
Law and by Loral's Memorandum of Association and its Second Amended and 
Restated Bye-Laws ("Loral's Bye-Laws"). Orion was incorporated in the State 
of Delaware on June 26, 1996 under the name Orion Newco Services, Inc., and 
in January 1997, changed its name to Orion Network Systems, Inc. Orion is the 
successor of Orion Network Systems, Inc. incorporated in the State of 
Delaware on October 26, 1982 (inception) under the name Orion Satellite 
Corporation, which in January 1988 changed its name to Orion Network Systems, 
Inc. The rights of its shareholders are governed by the DGCL and its Restated 
Certificate of Incorporation, as amended ("Orion's Certificate of 
Incorporation"), and its Amended and Restated By-Laws ("Orion's By-Laws"). 

   The following is a summary of certain material differences between the 
rights of holders of Orion's securities and the rights of holders of Loral's 
securities, as contained in provisions of Bermuda Law and the DGCL and in 
Loral's and Orion's constitutional documents. This summary is not a 
comprehensive description of such laws and documents and is qualified in its 
entirety by appropriate reference to Bermuda Law and to the DGCL and to the 
constitutional documents of Loral and Orion. The indication of certain 
specific differences is not meant to indicate that other equally or more 
significant differences do not exist. 

DIVIDENDS 

   Under the DGCL, dividends may be declared by the Board of Directors at any 
regular or special meeting. Under Bermuda Law, a company may pay such 
dividends as are declared from time to time by its Board of Directors unless 
there are reasonable grounds for believing that Loral is or would, after the 
payment, be unable to pay its liabilities as they become due or that the 
realizable value of its assets would thereunder be less than the aggregate of 
its liabilities and issued share capital and share premium accounts. 

                                       77
<PAGE>
VOTING RIGHTS 

   Under both the DGCL and Bermuda Law, questions brought before a general 
meeting of shareholders are decided by a majority vote of shareholders 
present at the meeting (or by such majority as the DGCL or Bermuda Law or the 
bye-laws prescribe). 

RIGHTS IN LIQUIDATION 

   Under Orion's Certificate of Incorporation, the Board of Directors is 
empowered to determine the rights awarded to any series of preferred stock in 
the event of voluntary or involuntary liquidation, dissolution or winding up 
of Orion. Under Bermuda Law, in the event of liquidation, dissolution or 
winding up of a company, after satisfaction in full of all claims of 
creditors and subject to the preferential rights accorded to any series of 
preferred shares, the proceeds of such liquidation, dissolution or winding up 
are distributed pro rata among the holders of common shares, after 
satisfaction of the obligations with respect to the preferred shares, if any. 

MEETINGS OF SHAREHOLDERS 

   Under Orion's By-Laws, annual meetings of stockholders shall be held on 
the first Thursday of May, if not a legal holiday. The DGCL permits special 
meetings of shareholders to be called by the Board of Directors and such 
other persons, including shareholders, as the certificate of incorporation or 
bylaws may provide. Orion's Certificate of Incorporation provides that 
special meetings may be called by the president or the Board of Directors and 
shall be called by the president or secretary at the request in writing of 
two or more stockholders owning at least 35% in amount of the entire capital 
stock of the corporation issued and outstanding and entitled to vote, if no 
special meeting of stockholders has been called and held at the request of 
stockholders within the six months preceding such written request. Under 
Orion's By-Laws, shareholders must be given at least ten days' advance 
written notice of a general meeting. 

   Under Orion's By-Laws, the holders of a majority of the stock issued and 
outstanding and entitled to vote, present in person or represented by proxy, 
shall constitute a quorum, except as otherwise provided by statute or by 
Orion's Certificate of Incorporation. 

   Under Bermuda Law, a company is required to convene an Annual General 
Meeting once in every calendar year. Bermuda Law provides that a Special 
General Meeting may be called by the Board of Directors. A Special General 
Meeting may also be convened at the request of shareholders holding not less 
than 10% of such of the paid-up capital of Loral carrying the right to vote 
at General Meetings of Loral. Bermuda Law also requires that shareholders be 
given at least five days' advance notice of a general meeting but the 
accidental omission of notice to any person does not invalidate the 
proceedings at a meeting. 

   Under Bermuda Law, the number of shareholders constituting a quorum at any 
general meeting of shareholders is determined by the bye-laws of a company. 
Loral's Bye-Laws provide that except as set forth under certain anti-takeover 
provisions of the Bye-Laws, the presence in person or by proxy of the holders 
of more than 50% of the voting capital stock of Loral constitutes a quorum. 

ACCESS TO BOOKS AND RECORDS AND DISSEMINATION OF INFORMATION 

   Under the DGCL, Orion's shareholders and directors have a general right to 
inspect the corporation's stock ledger, a list of stockholders and its other 
books and records. 

   Under Bermuda Law, members of the general public have the right to inspect 
the public documents of a company available at the office of the Registrar of 
Companies in Bermuda. These documents include Loral's certificate of 
incorporation, its memorandum of association (including its objects and 
powers) and any alteration to Loral's memorandum of association. The 
shareholders have the additional right to inspect the bye-laws of Loral, 
minutes of general meetings and Loral's audited financial statements, which 
must be presented at the annual general meeting. The register of shareholders 
of a company is also open to inspection by shareholders without charge and to 
members of the general public upon the payment of 

                                       78
<PAGE>
a fee. A company is required to maintain its share register in Bermuda but 
may, subject to the provisions of Bermuda Law, establish a branch register 
outside Bermuda. A company is required to keep at its registered office a 
register of its directors and officers which is open for inspection for not 
less than two hours in each day by members of the public without charge. 
Bermuda Law does not, however, provide a general right for shareholders to 
inspect or obtain copies of any other corporate records. 

BOARD OF DIRECTORS 

   Under the DGCL, the Board of Directors of a Delaware corporation shall 
consist of one or more directors as fixed by the certificate of incorporation 
or by-laws. Under Orion's Certificate of Incorporation, the number of 
directors shall be not less than 3 and not more than 15. Currently, under 
Orion's By-laws, Orion's Board of Directors consists of 10 members. 

   Under Loral's Bye-Laws, the numbers of directors shall be not less than 2 
nor more than 15, as Loral may from time to time determine. 

   Both Orion's and Loral's boards of directors are divided into three 
classes, designated as Class I, Class II and Class III, as nearly equal in 
number as possible. 

ELECTION OR REMOVAL OF DIRECTORS 

   Under Orion's Certificate of Incorporation and By-Laws, the directors are 
elected at the meeting of stockholders by or at the direction of the Board of 
Directors or by any stockholder entitled to vote for the election of 
directors who complies with certain notice procedures for a term expiring at 
the third succeeding annual meeting and in all cases until their successors 
shall be elected and shall qualify, or until their earlier resignation, 
removal from office, death or incapacity. There shall be no cumulative voting 
rights for the election of directors. 

   The DGCL provides that directors may be removed from office with or 
without cause, by the holders of a majority of the voting power of all 
outstanding voting stock, unless the corporation has a classified board and 
its certificate does not otherwise provide, in which case directors may be 
removed only for cause. Orion's Certificate of Incorporation does not 
otherwise provide. 

   Under Bermuda Law and Loral's Bye-Laws, directors are elected at the 
Annual General Meeting or elected or appointed in such other manner as 
provided for in Loral's Bye-Laws until their successors are elected or 
appointed, unless they are earlier removed or resign. 

   Under Bermuda Law and Loral's Bye-Laws and subject to the provisions 
described under certain provisions of the Bye-Laws, a director may be removed 
at a Special General Meeting of shareholders specifically called for that 
purpose, provided that the director was served with at least 14 days' notice. 
The director has a right to be heard at the meeting. Any vacancy created by 
the removal of a director at a Special General Meeting may be filled at such 
meeting by the election of another director in his or her place or, in the 
absence of any such election, by the Board of Directors. 

AMENDMENT OF ORION'S CERTIFICATE OF INCORPORATION, LORAL'S MEMORANDUM OF 
ASSOCIATION AND BYE-LAWS 

   Under the DGCL, holders of a majority of the voting power of a corporation 
and, when provided in the certificate of incorporation, the directors of the 
corporation, have the power to adopt, amend and repeal the bylaws of a 
corporation. Orion's Certificate of Incorporation grants the directors of 
Orion such power. 

   Under the DGCL, amendment of the certificate of incorporation shall be 
made by a resolution of the Board of Directors setting forth the amendment, 
declaring its advisability, and either calling a special meeting of the 
shareholders entitled to vote or directing that the amendment proposed be 
considered at the next annual meeting of the shareholders. The DGCL requires 
that, unless a different percentage is provided for, a majority of the voting 
power of the corporation is required to approve the amendment of the 
certificate of incorporation at the shareholders meeting. Orion's Certificate 
of Incorporation requires the affirmative vote of two-thirds of the stock 
entitled to vote and the affirmative vote of the Board of 

                                       79
<PAGE>
Directors in order to amend the provisions of Orion's By-Laws concerning the 
capital stock, the number of directors and their election, the redemption of 
stock, the control share acquisitions and certain business combinations, the 
indemnification, and the meeting of shareholders. 

   Bermuda Law provides that the Memorandum of Association of a company may 
be amended by a resolution passed at a General Meeting of shareholders of 
which due notice has been given. In addition, the holders of the Loral Series 
A Preferred Stock have the right to approve, voting as a separate class, any 
amendments to the Memorandum of Association or Bye-Laws of Loral if such 
amendment would adversely affect the rights, powers, privileges or 
preferences of the Loral Series A Preferred Stock. An amendment to the 
Memorandum of Association of a company other than an amendment which alters 
or reduces a company's share capital as provided in Bermuda Law also requires 
the approval of the Bermuda Minister of Finance, who may grant or withhold 
approval at his discretion. 

   Under Bermuda Law, the holders of an aggregate of no less than 20% in par 
value of a company's issued share capital have the right to apply to the 
Bermuda Court for an annulment of any amendment of the memorandum of 
association adopted by shareholders at any general meeting, other than an 
amendment which alters or reduces a company's share capital as provided in 
Bermuda Law. Where such an application is made, the amendment becomes 
effective only to the extent that it is confirmed by the Bermuda Court. An 
application for amendment of the memorandum of association must be made 
within 21 days after the date on which the resolution altering Loral's 
memorandum is passed and may be made on behalf of the persons entitled to 
make the application by one or more of their number as they may appoint in 
writing for the purpose. No such application may be made by persons voting in 
favor of the amendment. 

APPRAISAL RIGHTS AND SHAREHOLDER SUITS 

   Under the DGCL, stockholders may exercise a right of dissent from certain 
corporate actions and obtain payment of the fair value of their stock. This 
remedy is an exclusive remedy, except where the corporate action involves 
fraud or illegality. Under the DGCL, appraisal rights are available to 
dissenting shareholders in connection with certain mergers or consolidations. 
However, unless the certificate of incorporation otherwise provides, the DGCL 
does not provide for appraisal rights (i) if the stock of the corporation are 
listed on a national securities exchange or designated as a national market 
systems security on an interdealer quotations system by the NASD or held of 
record by more than 2,000 shareholders (as long as the shareholders receive 
in the merger shares of the Surviving Corporation or of any other corporation 
the shares of which are listed on a national securities exchange or 
designated as a national market systems security on an interdealer quotations 
system by the NASD or held of record by more than 2,000 shareholders) or (ii) 
if the corporation is the Surviving Corporation and no vote of its 
shareholders is required for the merger. Orion's Certificate of Incorporation 
provides that Orion's shareholders other than the acquiring person will be 
entitled to dissenter's rights in the event control shares acquired in a 
control share acquisition are accorded full voting rights and the acquiring 
person has acquired control shares with a majority or more of all voting 
power. 

   Under Bermuda Law, in the event of an amalgamation of two Bermuda 
companies, a shareholder who did not vote in favor of the amalgamation and 
who is not satisfied that fair value has been paid for his shares may apply 
to the Bermuda Court to appraise the fair value of his shares. The 
amalgamation of a company with another company requires the amalgamation 
agreement to be approved by the Board of Directors and by a meeting of the 
holders of shares of the amalgamating company of which they are directors and 
of the holders of each class of such shares. Under Bermuda Law, an 
amalgamation also requires the consent of the Bermuda Minister of Finance, 
who may grant or withhold consent at his discretion. 

   Class actions and derivative actions are generally not available to 
shareholders under Bermuda Law. The Bermuda courts, however, would ordinarily 
be expected to permit a shareholder to commence an action in the name of a 
company to remedy a wrong done to Loral where an act committed by Loral is 
alleged to be beyond the corporate power of Loral or is illegal or would 
result in the violation of Loral's 

                                       80
<PAGE>
memorandum of association or bye-laws. Furthermore, consideration would be 
given by the court to acts that are alleged to constitute a fraud against the 
minority shareholders or, for instance, where an act requires the approval of 
a greater percentage of Loral's shareholders than those who actually approved 
it. 

   When the affairs of a company are being conducted in a manner oppressive 
or prejudicial to the interests of some part of the shareholders, one or more 
shareholders may apply to the Bermuda Court for an order regulating Loral's 
conduct of affairs in the future or ordering the purchase of the shares by 
any shareholder, by other shareholders or by Loral. 

REDEMPTION RIGHTS 

   Stock of Orion will always be subject to redemption by the corporation, by 
action of the Board of Directors, if it in its judgment such action should be 
taken, to the extent necessary to prevent the loss or secure the 
reinstatement of any license or franchise from any governmental agency held 
by Orion or any of its subsidiaries to conduct any portion of the business of 
Orion or any of its subsidiaries, which license or franchise is conditioned 
upon some or all of the holders of Orion's stock possessing prescribed 
qualifications. 

   Under Loral's Bye-Laws, Loral may from time to time by resolution 
authorize the reduction of its issued share capital or any capital 
redemption. 

INDEMNIFICATION 

   The DGCL contains provisions setting forth conditions under which a 
corporation may indemnify its directors, officers, employees and agents. 
While indemnification is permitted only if certain statutory standards of 
conduct are met, the DGCL provides for indemnification if the person acted in 
good faith and in a manner the personal reasonably believed to be in or not 
opposed to the best interests of the corporation and, with respect to any 
criminal action or proceeding, had no reasonable cause to believe the conduct 
was unlawful. 

   Under Orion's Certificate of Incorporation, every director, officer, 
employee and agent shall be indemnified against all proceeding; provided, 
however, that Orion shall indemnify an eligible person in connection with a 
proceeding initiated by such person only if the proceeding was authorized by 
Orion's Board of Directors. 

   Under the DGCL, a corporation's certificate of incorporation may contain a 
provision limiting or eliminating a director's personal liability to the 
corporation or its stockholders for monetary damages for a director's breach 
of fiduciary duty subject to certain limitations. Orion's Certificate of 
Incorporation contains a provision that eliminates the liability of Orion's 
directors to Orion or its stockholders for monetary damages for breach of 
fiduciary duty as a director. The provision does not change the liability of 
a director for a breach of duty of loyalty to Orion or its stockholders, for 
acts or omissions not in good faith or which involve intentional misconduct 
or a knowing violation of law, or for unlawful payment of dividend or 
unlawful stock purchase or redemption, or for any transaction from which the 
director derived an improper personal benefit. 

   Under Loral's Bye-Laws, every director, officer and member of a committee 
shall be indemnified out of the funds of Loral against all civil liabilities, 
loss, damage or expense incurred or suffered by him as such director, officer 
or committee member and the indemnity shall extend to any person acting as a 
director, officer or committee member in the reasonable belief that he has 
been so appointed or elected notwithstanding any defect in such appointment 
or election. 

BUSINESS COMBINATIONS 

   The DGCL requires approval of mergers, consolidations and dispositions of 
all or substantially all of a corporation's assets (other than so-called 
parent-subsidiary mergers) by a majority of the voting power of the 
corporation, unless the certificate of incorporation specifies a different 
percentage. Orion's Certificate of Incorporation contains a provision which 
restricts certain business combination transactions 

                                       81
<PAGE>
with an interested stockholder for two years after such stockholder has 
acquired 20% of the voting power. Under Orion's Certificate of Incorporation, 
if a business combination (including a merger, disposition of substantial 
assets, issuance of securities and other similar transactions) occurs with a 
person, who together with its affiliates, owns 20% or more of the outstanding 
capital stock of Orion (an "interested stockholder"), then the combination 
must be approved by the holders of at least a majority of the voting power of 
the then outstanding shares of capital stock of Orion entitled to vote, 
voting together as a single class and the holders of at least a majority of 
the voting stock, voting together as a single class, excluding the interested 
stockholders and their affiliates. 

   However, the combination may occur without such a vote if, among other 
exceptions, those directors who were directors before the acquiring party 
became an interested stockholder approve the combination by a unanimous vote. 

   Pursuant to Loral's Bye-Laws, the affirmative vote of shareholders of at 
least 80% of the shares of Loral carrying voting rights then outstanding 
shall be necessary to approve any business combination (including a merger, 
disposition of substantial assets, issuance of securities or other similar 
transactions) proposed by a person, who together with its affiliates, owns 
15% or more of the shares carrying voting rights by an interested 
shareholder. However, the combination may occur without such a vote, if, 
among other exceptions, those directors who were directors before the 
acquiring party become an interested shareholder approve the combination by 
not less than a majority. 

OTHER ANTI-TAKEOVER PROVISIONS 

   The DGCL does not contain a control share acquisition statute which 
restricts the voting rights of a person who acquires a controlling interest 
in the corporation to those voting rights which are conferred by the 
stockholders at a meeting. Orion's Certificate of Incorporation contains a 
control share acquisition provision which requires approval by disinterested 
shareholders of any acquisition of voting power above specified levels of 
ownership of Orion's stock.

        SELECTED CONSOLIDATED FINANCIAL AND OPERATIONAL DATA OF ORION 
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) 

   The following selected consolidated statements of operations and balance 
sheet data as of and for the years ended December 31, 1992, 1993, 1994, 1995 
and 1996 are derived from Orion's audited consolidated financial statements. 
The selected consolidated statements of operations and balance sheet data as 
of September 30, 1997 and for the nine months ended September 30, 1996 and 
1997 are derived from the unaudited consolidated financial statements of 
Orion and, in the opinion of Orion, include all adjustments consisting of 
normal accruals, necessary for a fair presentation of such information. 
Operating results for the nine months ended September 30, 1997 are not 
necessarily indicative of the results that may be achieved for the year 
ending December 31, 1997. The pro forma consolidated statements of operations 
and balance sheet data are derived from unaudited pro forma condensed 
consolidated financial statements. The pro forma data is not necessarily 
indicative of the results that would have been achieved nor are they 
indicative of Orion's future results. The data should be read in conjunction 
with the Consolidated Financial Statements, related notes and other financial 
information of Orion incorporated herein by reference. From its inception in 
1982 through January 20, 1995, when Orion 1 commenced commercial operations, 
Orion was a development stage enterprise. Because Orion's wholly owned 
subsidiary, Orion Network Services, Inc., has exclusive management and 
control of Orion Atlantic as its sole general partner, and Orion's 41 2/3% 
partnership interest, the financial statements of Orion Atlantic are 
consolidated with the financial statements of Orion. 

   In January 1997, Orion consummated the January Merger as part of a series 
of transactions which significantly changed Orion. Those transactions, which 
are discussed in more detail under "Information About Orion" of this Proxy 
Statement/Prospectus are as follows: 

   (i)   the Exchange; 

   (ii)  the acquisition by Orion of the only outstanding minority interest 
in Orion's subsidiary Orion Network Systems-Asia Pacific, Inc. from British 
Aerospace Satellite Investments, Inc., in exchange (the "OAP Acquisition") 
for approximately 86,000 shares of Orion Common Stock; 

   (iii) the Bond Offering; and 

   (iv) the Debentures Offering. 

   The Exchange and the OAP Acquisition resulted in Orion owning 100% of 
Orion Atlantic and its other significant subsidiaries and, therefore, a 
greatly simplified corporate structure. The Exchange also resulted in a 
significant increase in Orion's Capital Stock outstanding. The net proceeds 
of the Bond Offering and the Debentures Offering were used by Orion to repay 
the credit facility it entered into in connection with the construction of 
the Orion 1 satellite, to pre-fund the first three years of interest payment 
on certain of the Notes, and will be used by Orion for the construction and 
launch of two additional satellites, Orion 2 and Orion 3.

       Transactions (see "Information About Orion"), assuming such events 
       occurred on January 1, 1996. 
(2)    In 1993, Orion Atlantic terminated its commitment to purchase a second 
       satellite from MMS Space Systems, resulting in a termination charge of 
       $5 million. 
(3)    As required by GAAP, net loss is presented before accretion of 
       preferred stock and preferred stock dividends. For the years ended 
       December 31, 1992, 1993, 1994, 1995, 1996, 1996 (pro forma) and the 
       nine months ended September 30, 1996 and 1997 preferred stock dividends 
       and accretion are $0.0, $0.0, $0.6, $1.3, $1.4, $9.3, $1.0, and $6.3 
       million, respectively. 
(4)    Computed on the basis described for net loss per common share in Note 2 
       to the Consolidated Financial Statements incorporated herein by 
       reference from Orion's 1996 Form 10-K.

(6)    Sites includes installed VSATs and additional transmission destinations 
       (such as customer premises) that share a VSAT. 
(7)    Restricted and segregated cash represents (i) $116 million that has 
       been placed in a pledged account to fund the payment of the first six 
       scheduled payments of interest on the Senior Notes and (ii) $244 
       million that will be segregated by Orion and used only to invest in 
       certain high quality short term investments to make payments for 
       additional satellites and certain related costs. 
(8)    Represents amounts invested by the former limited partners of Orion 
       Atlantic (net of syndication costs related to the investments), 
       adjusted for such limited partners' share of net losses. The interests 
       of the limited partners were acquired by Orion in the Exchange.

(1)    Financial information for the four years in the period ended March 31, 
       1996, represent the space and communications operations of Old Loral. 
       The results of operations for the four years in the period ended March 
       31, 1996 include allocations and estimates of certain expenses of Loral 
       based upon estimates of actual services performed by Old Loral on 
       behalf of Loral. Interest expense for the four years in the period 
       ended March 31, 1996, was allocated to Loral based on Old Loral's 
       historical weighted average interest rate applied to the average 
       investment in affiliates. Management of Loral believes such allocations 
       are based on reasonable allocation methods.

       Standards No. 106 "Accounting for Postretirement Benefits Other than 
       Pensions," in fiscal 1993 net of related income taxes. 
(4)    In 1997, Loral acquired the remaining portion of SS/L it did not own 
       and, accordingly, began consolidating the operating results of SS/L 
       from January 1, 1997. Prior to January 1, 1997, SS/L was accounted for 
       using the equity method of accounting. In addition, the results of 
       operations for the nine months ended September 30, 1997 reflect the 
       operations of Skynet from March 14, 1997, the date of acquisition.

       share of the Loral Series A Preferred Stock and the Loral Common stock 
       (which Loral is required to disclose herein in accordance with 
       applicable Bermuda law) was $4.80 and $4.79 and $4.52 and $4.51, 
       respectively. Book value per share represents the quotient obtained by 
       dividing shareholders' equity by the number of outstanding shares of 
       Common Stock, giving effect to the conversion of the Loral Series A 
       Preferred Stock, plus, in the case of such preferred stock, the $.01 
       liquidation preference thereof. The book value per share and pro forma 
       book value per share of Loral Series C Preferred Stock as of September 
       30, 1997 is equal to its liquidation value of $50.00 per share.

                             FINANCIAL STATEMENTS 
  AS OF SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 
                            AND DECEMBER 31, 1996 

   The following unaudited pro forma condensed consolidated balance sheet as 
of September 30, 1997 and statements of operations for the nine months ended 
September 30, 1997 and December 31, 1996 give effect to 1) the acquisition of 
a 49% indirect economic interest in SatMex completed on December 29, 1997, 
which will be accounted for using the equity method of accounting, 2) the 
acquisition between March 25, 1997 and June 23, 1997 by Loral of the 
remaining SS/L common stock not previously owned, pursuant to agreements 
negotiated in February 1997, 3) the acquisition by Loral of Skynet on March 
14, 1997, and 4) the proposed acquisition by Loral of Orion which is subject 
to regulatory and Orion shareholder approvals and is expected to close in the 
first quarter of 1998. The SS/L and Skynet acquisitions are reflected in 
Loral's historical unaudited condensed consolidated balance sheet as of 
September 30, 1997 and the unaudited pro forma condensed consolidated balance 
sheet assumes the SatMex acquisition and the proposed Orion acquisition 
occurred as of September 30, 1997. The unaudited pro forma condensed 
consolidated statements of operations assume that these acquisitions occurred 
as of April 1, 1996. The unaudited pro forma condensed consolidated statement 
of operations for the nine months ended September 30, 1997 is based on the 
historical unaudited condensed consolidated statement of operations of Loral 
which includes the results of operations for SS/L from January 1, 1997 and 
the related minority interest, and Skynet for the period March 14, 1997 to 
September 30, 1997. The historical Loral condensed consolidated statement of 
operations for the nine months ended December 31, 1996 reflect the results of 
operations from the inception of Loral in April 1996 through December 31, 
1996. The unaudited pro forma condensed consolidated statement of operations 
information for the nine months ended December 31, 1996 is based on the 
historical condensed consolidated statements of operations of Loral and Orion 
as well as the condensed statements of operations of SS/L and Skynet for that 
period. The unaudited pro forma condensed statements of operations for Orion 
for the nine months ended December 31, 1996 and September 30, 1997 reflect 
the pro forma effects of certain transactions completed by Orion in January 
1997, as if such transactions had occurred January 1, 1996. Equity in the net 
loss of SatMex has been included in the unaudited pro forma condensed 
consolidated statements of operations for the nine months ended September 30, 
1997 and December 31, 1996, based on Loral's share of the pro forma results 
of SatMex for such periods. The unaudited pro forma condensed consolidated 
financial statements reflect the purchase method of accounting and the 
adjustments and assumptions described in the accompanying notes. 

   Pending completion of valuations and allocation of their respective fair 
values, the pro forma adjustments for SS/L, Skynet and SatMex are based upon 
preliminary estimates of fair values and the pro forma adjustments for Orion 
are based on historical values of assets and liabilities. Actual adjustments 
will be based on final appraisals and other analyses of fair values, which 
are not expected to result in material adjustments. The unaudited pro forma 
condensed consolidated balance sheet and statements of operations should be 
read in conjunction with the audited consolidated financial statements and 
notes of the respective companies. The unaudited pro forma condensed 
consolidated statements of operations data may not be indicative of the 
results that actually would have occurred if the acquisitions had taken place 
on April 1, 1996, or future results.

             NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED 
                             FINANCIAL STATEMENTS 

  AS OF SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 
                            AND DECEMBER 31, 1996 

1. The following facts and assumptions in notes (a) through (d) were used in 
   determining the effect on the pro forma statements of operations for the 
   increase in Loral's ownership of SS/L to 100%. Such transactions are 
   reflected in Loral's September 30, 1997 historical balance sheet. 

   (a) Pursuant to agreements negotiated in December 1996 and February 1997, 
       Loral acquired 49% of SS/L from four international aerospace and 
       communications companies (the "Alliance Partners") between March 25, 
       1997 and June 23, 1997 for $374 million. These transactions, in which 
       Loral acquired 24.5% of SS/L for $93.5 million in cash and $93.5 
       million in convertible preferred equivalent obligations ("CPEOs"), and 
       the remaining 24.5% of SS/L acquired on June 23, 1997 for 8,042,922 
       shares of Loral Common Stock and 1,063,663 shares of Loral Series C 
       Preferred Stock are reflected in Loral's historical unaudited 
       condensed consolidated balance sheet as of September 30, 1997. On June 
       5, 1997, the CPEOs were exchanged into shares of Loral's Series C 
       Preferred Stock after shareholder approval (the "Exchange"). 
       In August 1996, Loral increased its ownership of SS/L to 51% through 
       the acquisition of an 18.3% interest held by certain partnerships 
       affiliated with Lehman Brothers (the "Lehman Partnerships") for $110.0 
       million including cash of $4 million, 7.5 million shares of Loral 
       Common Stock, and 267,256 shares of common stock of Globalstar 
       Telecommunications Limited previously held by a Loral subsidiary. In 
       accordance with the terms of Loral's agreement with the Lehman 
       Partnerships, the purchase price was increased by $9.2 million in 
       April 1997. 

       Loral increased its ownership of SS/L to 75.5% and entered into 
       agreements to acquire the remaining 24.5% during the first quarter of 
       1997. Accordingly, Loral discontinued the equity method of accounting 
       and began consolidating the results of SS/L as of January 1, 1997, 
       with a reduction for SS/L's earnings attributable to its other 
       shareholders. 

       The acquisition of SS/L common stock has been accounted for as a 
       purchase. The cost in excess of net assets acquired arising from this 
       acquisition is being amortized over 40 years. A pro forma adjustment 
       of $1.7 million to amortization expense was made to the unaudited pro 
       forma condensed consolidated statement of operations for the nine 
       months ended December, 31, 1996. Loral's historical unaudited 
       condensed consolidated statement of operations for the nine months 
       ended September 30, 1997 reflects the results of operations of SS/L 
       from January 1, 1997 and the related minority interest of the SS/L 
       equity not owned by Loral during the period. Loral's historical 
       unaudited condensed consolidated statement of operations for the nine 
       months ended December 31, 1996 includes SS/L's operations using the 
       equity method of accounting. Pro forma adjustments assume that Loral 
       had acquired 100% of the common stock of SS/L as of April 1, 1996. 

   (b) The purchase price for SS/L was determined through arm's length 
       bargaining between Loral and the Alliance Partners and Loral and the 
       Lehman partnerships. The cash portion of the acquisition was financed 
       with cash on hand. The unaudited pro forma condensed consolidated 
       statements of operations reflect charges for interest expense of 7% on 
       the cash portion of the purchase price and 6% on the CPEOs and 
       preferred stock portion of the purchase price. Loral intends to 
       refinance the cash portion of the purchase price with debt. The fixed 
       payments under the CPEOs and preferred stock have been reflected as 
       interest expense for periods prior to the exchange. The interest 
       charge of 7% on the cash portion of the purchase price reflects the 
       interest rate on Loral's current borrowing under its revolving credit 
       facility. 

   (c) Other pro forma adjustments to the unaudited pro forma condensed 
       consolidated statement of operations for the nine months ended 
       September 30, 1997, include elimination of SS/L's sales to Skynet of 
       $24.8 million and related costs and expenses of $22.5 million for the 
       period January 1, 1997 through March 14, 1997. Other pro forma 
       adjustments to the unaudited pro forma 

                                       91
<PAGE>
       condensed consolidated statement of operations for the nine months 
       ended December 31, 1996 include elimination of SS/L's sales to Skynet 
       of $96.5 million and related cost of sales of $82.1 million and 
       elimination of Loral's equity in the net income of SS/L based on its 
       historical ownership interest during the period. 

   (d) A statutory (Federal and state) tax rate of 41%, adjusted for 
       non-deductible interest and goodwill, was assumed with respect to the 
       pro forma adjustments. 

2. The following facts and assumptions in notes (e) through (g) were used in 
   determining the pro forma effect of the acquisition of Skynet from AT&T. 
   On March 14, 1997 Loral acquired certain assets of Skynet for $478.1 
   million in cash. The price reflects a reduction from the $712.5 million 
   price originally agreed upon in September 1996 arising from an adjustment 
   resulting from the failure of Skynet's Telstar 401 satellite in January 
   1997. The price is subject to further adjustment based upon net assets 
   delivered at closing, as defined. 

   This acquisition has been accounted for as a purchase. Loral's historical 
   unaudited condensed consolidated statement of operations for the nine 
   months ended September 30, 1997 reflects the operations of Skynet from the 
   date of acquisition through September 30, 1997. The Skynet preacquisition 
   period January 1, 1997 through March 14, 1997 is presented in the 
   unaudited pro forma condensed consolidated statement of operations for the 
   nine months ended September 30, 1997. The Skynet historical unaudited 
   condensed consolidated statement of operations included in the unaudited 
   pro forma condensed consolidated statement of operations for the nine 
   months ended December 31, 1996 includes the operations of Skynet for the 
   entire period. The Skynet operations have been calculated by deducting the 
   Skynet operations for the three month period ended March 31, 1996 from the 
   Skynet operations for the year ended December 31, 1996. Revenues, 
   operating income and net income for Skynet for the three months ended 
   March 31, 1996 were $39.9 million, $19.0 million and $9.3 million, 
   respectively. Pro forma adjustments have been calculated for the nine 
   month period. 

   (e) The purchase price for Skynet was determined through arm's length 
       bargaining between Loral and AT&T. The acquisition was initially 
       financed with cash on hand. A portion of the purchase price is 
       expected to be refinanced with debt. The pro forma adjustment for 
       interest expense reflects charges for interest based on an adjusted 
       purchase price of $478.1 million for the period January 1, 1997 
       through March 14, 1997 and an unadjusted price of $712.5 million for 
       the nine months ended December 31, 1996 at an assumed interest rate of 
       7%, reduced for capitalized interest of $2.9 million for the period 
       January 1, 1997 through March 14, 1997 and $7.5 million for the nine 
       months ended December 31, 1996 and interest expense recorded by Skynet 
       of $2.5 million for the period January 1, 1997 through March 14, 1997 
       and $11.3 million for the nine months ended December 31, 1996. Loral 
       intends to refinance a portion of the purchase price with debt. The 
       interest charge of 7% on the cash portion of the purchase price 
       reflects the interest rate on Loral's current borrowing under its 
       revolving credit facility. The unadjusted purchase price of $712.5 
       million was used as the basis of the interest expense calculation 
       during the nine months ended December 31, 1996 because Telstar 401 was 
       operating and generating revenues during that entire period. 

   (f) During the fourth quarter of 1997, Loral revised its allocations of 
       fair values for the acquisition, which are included in Loral's 
       September 30, 1997 historical balance sheet. Such adjustments resulted 
       primarily in an increase to the value of the satellites and a 
       reduction in cost in excess of net assets acquired. Other adjustments 
       to the unaudited pro forma condensed consolidated balance sheet 
       include an additional accrual for long-term customer obligations 
       associated with the failure of Telstar 401 which reflects finalization 
       of lease obligations related to replacement and backup capacity for 
       sold transponders on Telstar 401. These adjustments and the resulting 
       changes in accumulated depreciation and amortization of cost in excess 
       of net assets acquired have been reflected in the pro forma balance 
       sheet as of September 30, 1997. After giving effect to such revised 
       allocations, The estimated excess of purchase price over net assets 
       acquired of $69.4 million is being amortized over 40 years. Other 
       purchase accounting adjustments to the 

                                       92
<PAGE>
       unaudited pro forma condensed consolidated statement of operations for 
       the period January 1, 1997 through March 14, 1997, pursuant to the 
       provisions of Accounting Principles Board Opinion No. 16, include 
       depreciation expense related to the excess of fair value over carrying 
       value of $89.2 million using estimated useful lives of 12.5 to 18 
       years. Other purchase accounting adjustments to the unaudited pro 
       forma condensed consolidated statement of operations for the nine 
       months ended December 31, 1996 include depreciation expense over an 
       estimated weighted average ten year life for the excess of fair value 
       over the carrying value of $278.6 million. For purposes of this 
       adjustment, the fair value of fixed assets includes an estimated fair 
       value of Telstar 401, and historical book value includes the carrying 
       value of Telstar 401. Additional pro forma adjustments to the 
       unaudited pro forma condensed consolidated statement of operations for 
       the nine months ended September 30, 1997 and December 31, 1996 include 
       $0.4 million and $1.3 million, of amortization of the excess of 
       purchase price over fair value and $0.7 million and $20.2 million of 
       depreciation expense related to the difference between the fair value 
       of assets acquired and their related carrying values. 

   (g) A statutory (Federal and state) tax rate of 39% was assumed with 
       respect to the pro forma adjustments. 

3. The following facts and assumptions in note (h) were used in determining 
   the pro forma effect of the investment in SatMex. 

   (h) Loral and Telefonica Autrey, (the "Sponsors") formed a joint venture 
       ("Holdings") which acquired, through a wholly owned subsidiary 
       ("Acquisition Sub"), 75% of the outstanding capital stock of SatMex 
       for $638.0 million, paid in two installments. The first installment 
       was paid on November 17, 1997 using $141.1 million of equity 
       contributed by the Sponsors and $52.5 million of debt incurred by 
       Acquisition Sub. Loral's investment was $91.7 million for a 49% 
       indirect economic interest in SatMex. As part of the Acquisition, 
       Holdings entered into a $125.1 million seven year obligation to the 
       Mexican government ("Government Obligation") in consideration for the 
       assumption by SatMex of the debt incurred in connection with the 
       Acquisition. The final installment plus interest, financed with debt 
       incurred by Acquisition Sub, was paid on December 29, 1997. Loral will 
       account for this investment under the equity method of accounting. The 
       unaudited pro forma condensed consolidated balance sheet reflects a 
       reduction in cash and increase in investments in affiliates to record 
       Loral's investment in SatMex. 

       Pro forma adjustments were made to the unaudited pro forma condensed 
       consolidated statements of operations for the nine months ended 
       September 30, 1997 and December 31, 1996 to reflect the equity in 
       earnings of SatMex as if the investment was made April 1, 1996. The 
       pro forma adjustments were based on the unaudited pro forma financial 
       statements of SatMex for the nine months ended September 30, 1997 and 
       the year ended December 31, 1996. Interim historical financial 
       statements of SatMex for the nine months ended December 31, 1996 are 
       not available. Therefore, net income for the nine months ended 
       December 31, 1996 was calculated on a pro rata basis using the 
       historical net income for the year ended December 31, 1996 adjusted 
       for a major customer contract entered into in October 1997. The pro 
       forma adjustments for the nine months ended December 31, 1996 were 
       calculated on a pro rata basis with the exception of financing fees 
       which were assumed to have been incurred on April 1, 1996. Management 
       believes that this method provides a reasonable approximation of 
       SatMex's historical and pro forma results of operations for the nine 
       months ended December 31, 1996.

       The cost in excess of net assets acquired has been assigned to the 
       orbital slot concessions received from the Mexican government 
       ("Concessions") and is being amortized over 40 years. Interest has 
       been reflected at rates ranging from 9.37% to 10.13% plus Mexican 
       withholding tax, and deferred financing and offering costs are being 
       amortized over 6 to 7 years, when the related debt matures. Other pro 
       forma adjustments have been made to reflect revenue and expenses on a 
       post-acquisition basis. Revenue adjustments reflect reduced revenues 
       from Telecomm based upon new contracts entered into concurrent with 
       the acquisition. Operating expense adjustments include increased 
       payroll cost to post-acquisition pay scales, increased in-orbit 
       insurance premiums driven by higher levels of insurance required due 
       to the financings, incremental lease costs, reversal of non-recurring 
       bad debt recoveries recorded in 1997, management and intellectual 
       property fees to be paid to the Sponsors and elimination of 
       non-recurring bonuses and employment costs related to the 
       privatization. Pro forma adjustments have been made to eliminate 
       assessments from the Mexican Government. A pro forma tax benefit has 
       been reflected on the pro forma adjustments and historical income. 

       Pro forma adjustments related to affiliates of Loral other than SatMex 
       include Loral's share of the Government Obligation interest expense 
       which accrues at 12% per year applied to the discounted amount of 
       $85.3 million and management and intellectual property fees payable 
       from SatMex to other Loral affiliates. 

       The unaudited pro forma condensed consolidated statements of 
       operations reflect charges for interest expense of 7% on the cash 
       portion of the purchase price. Loral intends to refinance a portion of 
       the purchase price with debt. The interest charge of 7% on the cash 
       portion of the purchase price reflects the interest rate on Loral's 
       current borrowing under its revolving credit facility. 

4. The following facts and assumptions were used in determining the pro forma 
   effect on Orion of the January merger, Exchange, Bond Offering and 
   Debentures Offering completed in January 1997 (see "Information about 
   Orion--Recent Developments"): 

   The unaudited pro forma condensed consolidated statements of operations 
   for the nine months ended September 30, 1997 and December 31, 1996 have 
   been prepared as if the transactions took place on April 1, 1996. The 
   unaudited pro forma condensed consolidated financial statements do not 
   purport to present the actual financial position or results of operations 
   of Orion had the transactions in fact

   occurred on the dates specified, nor are they indicative of the results of 
   operations that may be achieved in the future. The unaudited pro forma 
   condensed consolidated financial statements are based on the assumptions 
   and adjustments further described herein. 

The tables below illustrate the January Transaction adjustments made to the 
Orion historical statements of operations for the nine month periods ended 
September 30, 1997 and December 31, 1996. Certain historical items have been

5. The following facts and assumptions in notes (i) through (l) were used in 
   determining the pro forma effect of the proposed acquisition of Orion. 

   (i) On October 7, 1997, Loral agreed to acquire 100% of Orion's 
       outstanding capital stock for Loral common stock. The purchase price 
       of approximately $461.5 million, including estimated expenses of $5 
       million, was based on a closing price of $22.75 of Loral Common Stock 
       on December 2, 1997. The price was determined pursuant to the 
       requirements of APB No. 16 and EITF 95-19 and assumed the issuance of 
       19.1 million shares of Loral Common Stock (including the conversion of 
       Orion's redeemable convertible preferred stock and 8.75% convertible 
       debentures), the exchange of options and warrants to purchase common 
       stock and the elimination of the Orion shares held by SS/L. The 
       transaction is expected to close in the first quarter of 1998 and is 
       subject to regulatory and Orion shareholder approvals. At the close, 
       each share of Orion Capital Stock will be converted into $17.50 worth 
       of Loral Common Stock assuming the "determination price", as defined, 
       of Loral Common Stock is between $16.305 and $24.458. If the 
       determination price is at or outside either end of this range, each 
       Orion share will be converted into a fixed number of Loral common 
       shares obtained by dividing $17.50 by the high or low end of the 
       range, as appropriate. In no case will the exchange ratio be fewer 
       than 0.71553 shares of Loral Common Stock for each share of Orion 
       Capital Stock. The purchase price excludes the repurchase of Orion's 
       Senior Notes and Senior Discount Notes ("Notes"). Under certain change 
       in control provisions contained in the applicable agreements thereto, 
       Orion is required to offer to repurchase the Notes. Since the market 
       value of the Notes exceeds the call value, Loral does not believe the 
       noteholders will accept the repurchase offer. See "Risk Factors -- 
       Risk Related to the Transactions -- Offer to Purchase Orion's Senior 
       Notes and Senior Discount Notes." The unaudited pro forma condensed 
       consolidated balance sheet has been prepared as if the acquisition of 
       Orion's net assets had been completed on September 30, 1997. 

       This acquisition will be accounted for as a purchase. Pro forma 
       adjustments to the unaudited condensed consolidated statement of 
       operations have been calculated for the nine month periods ended 
       December 31, 1996 and September 30, 1997, respectively. These 
       unaudited pro 

                                       96
<PAGE>
       forma condensed consolidated statement of operations adjustments have 
       been prepared as if the proposed acquisition of Orion had occurred on 
       April 1, 1996. Orion operations have been calculated by deducting the 
       Orion operations for the three month period ended March 31, 1996 from 
       the Orion operations for the year ended December 31, 1996. Such 
       operations give effect on a pro forma basis to certain transactions 
       completed by Orion in January 1997, as if such transactions had been 
       completed January 1, 1996. Revenues, operating loss and net loss 
       attributable to common shareholders for Orion on a pro forma basis for 
       the three months ended March 31, 1996 were $7.6 million, $11.1 million 
       and $37.4 million, respectively. 

   (j) The estimated excess of purchase price over the net assets acquired of 
       $385.8 million is being amortized over 40 years. Orion's identifiable 
       assets and liabilities used in the preparation of these unaudited pro 
       forma condensed consolidated financial statements were based on 
       historical cost, pending the completion of an independent valuation 
       and allocation of their respective fair values, which are not expected 
       to result in material adjustments. Other pro forma adjustments to the 
       unaudited condensed consolidated balance sheet include (i) the assumed 
       conversion to equity at September 30, 1997 of Orion's Series A 8% 
       Cumulative Redeemable Convertible Preferred Stock aggregating $16.9 
       million at September 30, 1997 plus accrued dividends; Series B 8% 
       Cumulative Redeemable Convertible Preferred Stock aggregating $5.1 
       million at September 30, 1997 plus accrued dividends; Series C 6% 
       Cumulative Redeemable Convertible Preferred Stock aggregating $95.9 
       million at September 30, 1997 plus accrued dividends and $60.0 
       million, 8.75% convertible debentures dated January 31, 1997 and the 
       elimination of the accrued interest thereon; (ii) the elimination of 
       Orion's goodwill aggregating $21.1 million at September 30, 1997; and 
       (iii) the accrual of $.7 million relating to the assumed acceleration 
       of vesting of Non-Employee Director unvested stock options in 
       connection with the Merger. 

   (k) Other pro forma adjustments to the unaudited condensed consolidated 
       statement of operations include amortization expense of the 
       preliminary valuation of the excess purchase price, preferred 
       dividends, interest expense on the convertible debentures from the 
       historical Orion results and unearned compensation of $5.9 million and 
       the related amortization, resulting from the difference between the 
       purchase price and exercise price of unvested options. 

   (l) A tax benefit was recorded as an adjustment to the unaudited pro forma 
       condensed consolidated statement of operations for the nine months 
       ended December 31, 1996 and September 30, 1997 related to the Orion 
       loss which would have been available to Loral on its US income tax 
       return. A statutory (federal and state) tax rate of 40% was applied to 
       certain pro forma adjustments for the nine months ended September 30, 
       1997. 

6. Primary and fully diluted earnings per share are computed based upon the 
   weighted average number of shares of common stock and common equivalent 
   shares (Loral Series A Preferred Stock) outstanding, after giving pro 
   forma effect to the shares issued for the transactions described above. 
   The Loral Series C Preferred Stock was excluded from the earnings per 
   share calculations as their effect would have been anti-dilutive. 

   The following table presents the shares used in the pro forma earning 
   (loss) per share calculations (in thousands):

        days from January 15, 1998. More than one person may be deemed to be

                      AMENDMENTS TO DIRECTOR OPTION PLAN 
                                 (PROPOSAL 2) 

   The Board of Directors has approved and is proposing for stockholder 
approval amendments to the Director Option Plan. As indicated above, in the 
Merger each outstanding stock option to purchase shares of Orion Common Stock 
is to be converted into an option to acquire the number of shares of Loral 
Common Stock equal to the Exchange Ratio multiplied by the number of shares 
of Orion Common Stock for which such option was exercisable. In the case of 
the options granted under the Director Option Plan, Orion is seeking to 
effect the conversion of such options by amending the Director Option Plan. 
Orion also has amended its employee stock option plans to effect such 
conversion, but amendment of such employee stock option plans does not 
require stockholder approval and accordingly is not one of the matters to be 
acted upon at the Special Meeting. 

   Orion also is proposing to amend the Director Option Plan to provide that 
options granted to Orion's directors that vest at the next annual meeting of 
stockholders of Orion instead would vest upon consummation of the Merger, if 
the Merger occurs prior to such annual meeting. Orion believes that since its 
directors will have performed nearly a full year of service since the last 
annual meeting of stockholders, and since such directors would be resigning 
prior to the next annual meeting of stockholders to satisfy a condition of 
the Merger, it is appropriate for the directors' options to vest upon 
consummation of the Merger. 

   The Director Option Plan was adopted on March 20, 1996, with 380,000 
shares of Orion Common Stock reserved for issuance upon the exercise of 
options granted thereunder. To date, options to purchase 270,000 shares have 
been granted to non-employee directors of Orion, of which options to purchase 
80,000 shares granted at the 1997 annual meeting of stockholders of Orion 
(the "Unvested 1997 Options") have not yet vested and are scheduled to vest 
at the 1998 annual meeting of stockholders of Orion. Based upon the closing 
price of Orion's Common Stock on January 15, 1998, the aggregate market value 
of the total number of shares of Orion Common Stock underlying the Unvested 
1997 Options is $1,360,000. 

   The affirmative vote of a majority of the shares of Orion Common Stock and 
Orion Preferred Stock, present in person or represented by proxy and entitled 
to vote at the Annual Meeting, voting together as a single class, with each 
share of Orion Common Stock entitled to one vote per share, and each share of 
Orion Preferred Stock (including fractional shares) entitled to one vote for 
each whole share of Orion Common Stock that would be issuable upon conversion 
of such share of Orion Preferred Stock is required to approve the amendments 
to the Director Option Plan. Unless otherwise indicated, properly executed 
proxies will be voted in favor of Proposal 2 to approve the amendments to the 
Director Option Plan. If Proposal 2 is not approved by stockholders at the 
Special Meeting, Orion intends to rely on Loral's obligation in the Merger 
Agreement to ensure that stock options granted under the Director Option Plan 
are properly converted into options to acquire Loral Common Stock. 

           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 2. 

   The foregoing summary of the amendments to the Director Option Plan does 
not purport to be complete, and is subject to and qualified in its entirety 
by reference to the complete text of such amendments, which is attached 
hereto as Attachment D and is incorporated herein by reference. 

                    AMENDMENTS TO PUENTE OPTION AGREEMENT 
                                 (PROPOSAL 3) 

   The Board of Directors has approved and is proposing for stockholder 
approval amendments to the Puente Option Agreement. As indicated above, in 
the Merger each outstanding stock option to purchase shares of Orion Common 
Stock is to be converted into an option to acquire the number of shares of 
Loral Common Stock equal to the Exchange Ratio multiplied by the number of 
shares of Orion Common Stock for which such option was exercisable. In the 
case of the options granted under the Puente Option Agreement, Orion is 
seeking to effect the conversion of such options by amending the Puente 
Option Agreement. Orion also has amended its other stock option agreements 
through amendments to its 

                                      102
<PAGE>
employee stock option plans to effect such conversion, but amendment of such 
employee stock option plans does not require stockholder approval and 
accordingly is not one of the matters to be acted upon at the Special 
Meeting. 

   The Puente Option Agreement was entered into by Orion in connection with 
the establishment of Company's Executive Committee, the appointment of John 
G. Puente as Chairman of that committee and the retention of Mr. Puente as a 
consultant to Orion on matters of strategic importance to Orion. The 
Executive Committee is charged with overseeing, on behalf of the Board of 
Directors, the strategic direction of Orion's financing efforts, matters 
relating to strategic partners, alliances and acquisitions and the overall 
market focus of Orion, and played a significant role in Orion's decision to 
enter into the Merger Agreement. The Board of Directors believes that the 
Executive Committee has been very effective since its establishment and 
believes that Mr. Puente, as Chairman of that committee, contributed 
significantly to its effectiveness. 

   The affirmative vote of a majority of the shares of Orion Common Stock and 
Orion Preferred Stock, present in person or represented by proxy and entitled 
to vote at the Annual Meeting, voting together as a single class, with each 
share of Orion Common Stock entitled to one vote per share, and each share of 
Orion Preferred Stock (including fractional shares) entitled to one vote for 
each whole share of Orion Common Stock that would be issuable upon conversion 
of such share of Orion Preferred Stock is required to approve the amendments 
to the Puente Option Agreement. Unless otherwise indicated, properly executed 
proxies will be voted in favor of Proposal 3 to approve the amendments to the 
Puente Option Agreement. If Proposal 3 is not approved by stockholders at the 
Special Meeting, Orion intends to rely on Loral's obligation in the Merger 
Agreement to ensure that stock options granted under the Puente Option 
Agreement are properly converted into options to acquire Loral Common Stock. 

           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 3. 

   The foregoing summary of the amendments to the Puente Option Agreement 
does not purport to be complete, and is subject to and qualified in its 
entirety by reference to the complete text of such amendments, which is 
attached hereto as Attachment E and is incorporated herein by reference. 

                    AMENDMENTS TO HAUSER OPTION AGREEMENT 
                                 (PROPOSAL 4) 

   The Board of Directors has approved and is proposing for stockholder 
approval amendments to the Hauser Option Agreement. As indicated above, in 
the Merger each outstanding stock option to purchase shares of Orion Common 
Stock is to be converted into an option to acquire the number of shares of 
Loral Common Stock equal to the Exchange Ratio multiplied by the number of 
shares of Orion Common Stock for which such option was exercisable. In the 
case of the options granted under the Hauser Option Agreement, Orion is 
seeking to effect the conversion of such options by amending the Hauser 
Option Agreement. Orion also has amended its other stock option agreements 
through amendments to its employee stock option plans to effect such 
conversion, but amendment of such employee stock option plans does not 
require stockholder approval and accordingly is not one of the matters to be 
acted upon at the Special Meeting. 

   The Hauser Option Agreement was entered into by Orion in connection with 
the successful completion of the January 1997 Transactions. The Board of 
Directors believes that Mr. Hauser, as Chairman of Orion, contributed 
significantly to the successful completion of those transactions and granted 
options to Mr. Hauser pursuant to the Hauser Option Agreement to reward Mr. 
Hauser for his chairmanship of Orion during the period in which such 
transactions were planned, proposed and completed. 

   The affirmative vote of a majority of the shares of Orion Common Stock and 
Orion Preferred Stock, present in person or represented by proxy and entitled 
to vote at the Annual Meeting, voting together as a single class, with each 
share of Orion Common Stock entitled to one vote per share, and each share of 
Orion Preferred Stock (including fractional shares) entitled to one vote for 
each whole share of Orion Common Stock that would be issuable upon conversion 
of such share of Orion Preferred Stock is required 

                                      103
<PAGE>
to approve the amendments to the Hauser Option Agreement. Unless otherwise 
indicated, properly executed proxies will be voted in favor of Proposal 4 to 
approve the amendments to the Hauser Option Agreement. If Proposal 4 is not 
approved by stockholders at the Special Meeting, Orion intends to rely on 
Loral's obligation in the Merger Agreement to ensure that stock options 
granted under the Hauser Option Agreement are properly converted into options 
to acquire Loral Common Stock. 

           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 4. 

   The foregoing summary of the amendments to the Hauser Option Agreement 
does not purport to be complete, and is subject to and qualified in its 
entirety by reference to the complete text of such amendments, which is 
attached hereto as Attachment F and is incorporated herein by reference. 

                                OTHER MATTERS 

   No business may be brought before the Special Meeting other than the 
proposals and procedural matters that may arise in connection with the 
proposals set forth in this Proxy Statement/Prospectus. Any proposals by 
stockholders of Orion to be considered for inclusion in Orion's Proxy 
Statement relating to the 1999 Annual Meeting of Stockholders must be in 
writing and received by Orion, at its principal office, no later than 
December 26, 1998. Nothing in this paragraph shall be deemed to require Orion 
to include in the proxy statement relating to Orion's 1998 Annual Meeting of 
Stockholders any stockholder proposal that does not meet all of the 
requirements for such inclusion in effect at that time. 

                            LEGAL AND TAX MATTERS 

   Certain United States tax matters described under "The Merger -- Taxation 
of Loral and its Stockholders" have been passed upon for Loral by Willkie

                         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 

SECTION 1.1. 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 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. 

                                      A-8
<PAGE>
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 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 
officers and directors of the Surviving Corporation shall be directed and 
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. 

                                      A-9
<PAGE>
    The Exchange Ratio shall be as follows: 

   (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 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 

                                      A-10
<PAGE>
    (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 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 with such letter 
of transmittal duly 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 

                                      A-11
<PAGE>
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 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 

                                      A-12
<PAGE>
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. 

   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 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 

                                      A-13
<PAGE>
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 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). 

                                      A-14
<PAGE>
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. 

SECTION 3.3. CAPITALIZATION. 

   The authorized capital stock of the Company consists, as of September 30, 
1997, of: (a) 40,000,000 shares of Common Stock, of which 11,675,436 shares

the Company's Stock Option Plans, shares of Common Stock issued pursuant to 
the Company's Employee Stock Purchase Plan or 401(k) Plan and shares of 
Common Stock issued upon conversion of Preferred Stock and in payment of

forth above, except as set forth in Schedule 3.3, there are no options, 
warrants or other rights, agreements, arrangements or commitments of any 
character relating to the issued or unissued capital stock of the Company or 
any Company Subsidiary or obligating the Company or any Company Subsidiary to 
issue, deliver or sell any shares of capital stock of, or other equity 
interests, in the Company or any Company Subsidiary. Set forth on Schedule 
3.3 is a list of all options, warrants or other rights, agreements, 
arrangements or commitments of any character relating to the issued or 
unissued capital stock of the Company or any Company Subsidiary 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 shares of 
Capital Stock have been duly authorized and validly issued and are fully paid 
and nonassessable and not subject to preemptive rights. Except as set forth 
in Schedule 3.3, all of the outstanding shares of capital stock of each 
Company Subsidiary that is a corporation have been duly authorized and 
validly issued and are fully paid and nonassessable, and all of the 
partnership interests of each Company Subsidiary that is a partnership have 
been duly authorized and validly issued and, except pursuant to provisions of 
the applicable partnership agreement, are fully paid. With respect to each 
Company 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 

                                      A-15
<PAGE>
stock owned by the Company, are owned by the Company free and clear of any 
liens, security interests, pledges, agreements, claims, charges or 
encumbrances (collectively, the "Encumbrances"). 

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 
obtaining any necessary stockholder approval of the Merger, to perform its 
obligations hereunder and thereunder and to consummate the transactions 
contemplated hereby and thereby. Except for the approval of this Agreement by 
the stockholders of the Company in accordance with Delaware Law, the 
execution and delivery of this Agreement and the Principal Stockholder 
Agreement by the Company and the consummation by the Company of the 
transactions contemplated hereby and thereby have been duly and validly 
authorized by all necessary corporate action and no other corporate 
proceedings on the part of the Company are necessary to authorize this 
Agreement and the Principal Stockholder Agreement or to consummate the 
transactions contemplated hereby and thereby. Each of this Agreement and the 
Principal Stockholder Agreement has been duly executed and delivered by the 
Company and, assuming the due authorization, execution and delivery by 
Acquiror and Merger Sub, constitutes a legal, valid and binding obligation of 
the Company, enforceable in accordance with its terms, except as such 
enforceability may be limited by bankruptcy, insolvency, reorganization, 
moratorium and other similar laws of general applicability relating to or 
affecting creditors' rights generally and by the application of general 
principles of equity. 

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, statute, ordinance, rule, regulation, order, judgment or decree 
applicable to 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, result in any breach of or constitute a default (or an event 
which with or without notice or lapse of time or both would become a default) 
under, or give to others any rights of termination, amendment, acceleration 
or cancellation of, or result in the creation of an Encumbrance on any of the 
properties or assets of the Company or any Company Subsidiary pursuant to, 
any note, bond, mortgage, indenture, contract, agreement, lease, license, 
permit, franchise or other instrument or obligation to which the Company or 
any Company Subsidiary is a party or by which the Company, any Company 
Subsidiary or any of their respective properties or assets is bound or 
affected, except, in the case of clauses (ii) and (iii) above, for any such 
conflicts, violations, breaches, defaults or other 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 
to, any governmental or regulatory authority, domestic or foreign (each a 
"Governmental Entity"), by or with respect to the Company except (i) for (A) 
applicable requirements, if any, of the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), the Securities Act of 1933, as amended (the 
"Securities Act"), state securities or "blue sky" laws ("Blue Sky Laws"), 
state takeover laws, the National Association of Securities Dealers, Inc. 
(the "NASD") or the Nasdaq National Market ("Nasdaq"), the Hart-Scott-Rodino 
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), the 
Communications Act of 1934, as amended (the "Communications Act"), the 
Federal Communications Commission (the "FCC"), Telekommunikationsgesetz (TKG) 
and the German Telecommunications Installations Act, (B) applicable 
requirements, if any, of 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, 

                                      A-16
<PAGE>
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 its obligations under this 
Agreement in any material respect, and would not have a Company Material 
Adverse Effect. 

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 special), (iv) all reports on Form 8-K, and (v) all other 
reports or registration statements filed by the Company (collectively, the 
"Company SEC 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 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 

                                      A-17
<PAGE>
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 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). 

                                      A-18
<PAGE>
    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 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

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. 

   (c) Schedule 3.9(c) contains a list of all consultations and similar 
arrangements that have been effectuated with INTELSTAT, EUTELSAT and other 
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 such returns, reports, information statements and other documentation 
are 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, 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.

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,

source code), documentation, engineering and technical drawings, processes, 
methodologies, trade dress, mask works and technology, in 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 

                                      A-21
<PAGE>
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 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. 

   (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 

                                      A-22
<PAGE>
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

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

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

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

    (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

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 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

<PAGE>

any such conflicts, violations, breaches, defaults or other alterations or 
occurrences that would not prevent or delay consummation of the Merger in any 
material respect, or otherwise prevent Acquiror from performing its 
obligations under this Agreement in any material respect, and would not have 
an Acquiror Material Adverse Effect. 

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

financial statements of Acquiror included in the Acquiror 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 Acquiror SEC Reports (or incorporated by reference therein)

ordinary course of their businesses consistent with their past practices, and 
Acquiror and the Acquiror Subsidiaries have conducted their respective 
businesses in the ordinary course consistent with their past practices. 
Except set forth in Schedule 5.7, since June 30, 1997, there has not been any 
change in the business, condition (financial or otherwise) or results of 
operations of Acquiror and the Acquiror 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, an Acquiror 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 

                                      A-29
<PAGE>
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 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 
permits or contemplates revocation, modification or termination or any of 
Acquiror Permits or which would result in any material impairment of any 
rights thereunder, except where there would be no Acquiror Material Adverse 
Effect. The businesses of Acquiror and the Acquiror Subsidiaries are not 
being conducted in violation of any applicable law, statute, ordinance, 
regulation, judgment, Acquiror Permit, order, decree, concession, grant or 
other authorization of any Governmental Entity, except for violations that 
would not be reasonably likely to have an Acquiror Material Adverse Effect. 

   (b) Acquiror is not aware of any material difficulties in obtaining any 
IGO Determinations with respect to the Acquiror Satellites that are needed to 
operate the business of Acquiror and Acquiror Subsidiaries, taken as a whole, 
as it is now conducted, or for which Acquiror or any Acquiror Subsidiary has 
applied for an Acquiror Permit, except for those that would not have an 
Acquiror Material Adverse Effect. 

SECTION 5.10. TAXES. 

   Except as set forth in Schedule 5.10, Acquiror and the Acquiror 
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 such returns, reports, information 

                                      A-30
<PAGE>
statements and other documentation are correct and complete in all material 
respects. Except as set forth in Schedule 5.10, Acquiror and the Acquiror 
Subsidiaries have paid in full all Taxes (other than Taxes, the failure to 
pay which would not, individually or in the aggregate, have a Acquiror 
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, Acquiror has made adequate provision in its books 
and records and financial statements for such payment. Except as set forth in 
Schedule 5.10, Acquiror and the Acquiror Subsidiaries have withheld from 
payments made to its present or former employees, officers and directors all 
amounts required by law to be withheld, except where the liability would not, 
individually or in the aggregate, have a Acquiror 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 5.10 and except for such matters which would not individually or in 
the aggregate have an Acquiror Material Adverse Effect, (a) there are no 
assessments of, or claims against, Acquiror or the Acquiror Subsidiaries with 
respect to Taxes, that are outstanding; (b) no Governmental Entity is 
conducting an examination or audit of Acquiror or any Acquiror Subsidiary in 
respect of taxes; and (c) neither Acquiror nor any Acquiror Subsidiary has 
executed or filed any agreement extending the period of assessment or 
collection of any taxes which remain in effect. 

SECTION 5.11. INTELLECTUAL PROPERTY. 

   Unless expressly set forth otherwise on Schedule 5.11, Acquiror and 
Acquiror Subsidiaries own or 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 and any trade secrets, 
know-how, confidential information, material computer programs (including any 
source code), documentation, engineering and technical drawings, processes, 
methodologies, trade dress, mask works and technology, in each case material 
to the conduct of the business of Acquiror and Acquiror Subsidiaries taken as 
a whole (all of the foregoing items collectively referred to as the "Acquiror 
Intellectual Property"). Except as set forth on Schedule 5.11 or where there 
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 licenses by any person or entity; (c) to Acquiror'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; and (d) 
material Acquiror 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. 

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 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 

                                      A-31
<PAGE>
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 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.

SECTION 6.1. AFFIRMATIVE COVENANTS OF THE COMPANY. 

   The Company hereby covenants and agrees that, prior to the Closing Date,

to preserve substantially intact its business organization, maintain its 
rights and franchises, retain the services of its respective principal

principal customers and suppliers; (c) use its commercially reasonable

condition as at present, ordinary wear and tear excepted; (d) use its 
commercially reasonable efforts to keep in full force and effect insurance

prepare and file all tax returns required to be filed in a timely manner, and 
in a manner consistent with prior years and applicable laws and regulations; 
(f) timely file with the Commission all reports required to be filed under

requirements; (g) operate its business in accordance with the terms of its 
licenses, the Communications Act and the FCC rules and policies and in all

reasonable efforts to maintain each Key Company Permit in effect until the 
applicable construction projects are complete except where (x) the loss of 
such Key Company Permit or pending Key Application would not, individually or 
in the aggregate, have a Company Material Adverse Effect or (y) the 
maintenance of any such Company Permit would require an expenditure which 
would be in violation Section 6.2(e); (i) use its commercially reasonable 
efforts to enforce its rights to have the transmissions to and from the 
Company Satellites and Major Stations be free from interference from other 
radio communications facilities (existing or proposed), to the extent that 
such 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

in good faith the Company's request to take such action and not unreasonably 
withhold or delay its consent for such action.

execution and delivery of this Agreement, Acquiror and the Company shall 
cooperate and prepare and Acquiror shall file with the SEC a merger proxy 
registration statement on Form S-4 (together with the amendments thereof or 
supplements thereto, the "Proxy Registration Statement") in connection with 
the registration under the Securities Act of the Acquiror Shares to be issued 
pursuant to this Agreement and the approval by stockholders of the Company of 
the Merger. As promptly as practicable after the execution and delivery of 
this Agreement, the Company shall prepare for inclusion in the Proxy 
Registration Statement the information relating to the merger and approval of 
the merger by stockholders of the Company and any other information relating

Company relating thereto under the rules and regulations of the SEC. Such 
information furnished by the Company shall include the recommendation of the 
Company's Board of Directors in favor of approval and adoption of this 
Agreement and the Merger (subject to Section 7.10 hereof). Acquiror and the 
Company will cooperate in the production and filing of the Proxy Registration 
Statement, use all reasonable efforts to have or cause the Proxy Registration 
Statement to become effective as promptly as practicable, and take any action 
required to be taken under any applicable federal or state securities laws in 
connection with the issuance of Acquiror Shares pursuant to this Agreement 
and approval of this Agreement and the Merger by stockholders of the Company. 
None of the information supplied by any party hereto for inclusion in the 
Proxy Registration Statement will at the time the Proxy Registration 
Statement is filed with the SEC and at the time it becomes effective under 
the Securities Act, 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 statement therein, in light of the circumstances under 
which they are made, not misleading. 

   (b) Board Recommendation; Stockholder Approval. The Company shall, 
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 been obtained, or (B) 
except as otherwise provided in Section 7.15(g), commence an Exchange Offer. 

SECTION 7.4. FCC APPLICATION. 

   (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 shall jointly file, or cause to be filed, the FCC 
Application. Acquiror, Merger 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 consent as expeditiously as 
practicable. If the Closing shall not have occurred 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 

                                      A-36
<PAGE>
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. 

   (b) Acquiror and the Company shall each pay one-half (1/2) of any FCC fees 
that may be payable in connection with the filing or granting of approval of 
the FCC Application. The Company shall pay any cost incurred in connection 
with complying with the FCC notice and advertisement requirements in 
connection with the transfer of control of the Company. 

SECTION 7.5. HSR ACT MATTERS. 

   Acquiror, Merger Sub and the Company (as may be required pursuant to the 
HSR Act) promptly will complete all documents required to be filed with the

after the date hereof, together with the persons, if any, who are required to 
join in such filings, shall file such documents with the appropriate 
Governmental Entities. Acquiror, Merger Sub and the Company shall promptly 
furnish all materials thereafter required by any of the Governmental Entities 
having jurisdiction over such filings, and shall take all reasonable actions 
and shall file and use their best efforts to have declared effective or 
approved all documents and notifications with any such Governmental Entity, 
as may be required under the HSR Act or other federal or state antitrust laws 
for the consummation of the Merger and the other transactions contemplated 
hereby. Acquiror and the Company shall each pay one-half (1/2) of all filing 
fees related to compliance with the HSR Act in connection with the 
transactions contemplated hereby. 

SECTION 7.6. PUBLIC ANNOUNCEMENTS. 

   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 Market. 

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 of this Agreement, which provisions shall not be amended, repealed or 
otherwise 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. 

   (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 

                                      A-37
<PAGE>
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 provide benefits to the employees of the Company and the Company 
Subsidiaries 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 

                                      A-38
<PAGE>
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 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 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 

                                      A-39
<PAGE>
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 
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 

                                      A-40
<PAGE>
be deemed to have waived the delivery of the Requisite Consents as a closing 
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 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 

                                      A-41
<PAGE>
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 use in the 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 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 

                                      A-42
<PAGE>
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 

                                      A-43
<PAGE>
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

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;

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

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

required to be obtained, and all filings or notices required to be made, by 
the Company and the stockholders prior to consummation of the transactions

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

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. 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

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

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

relieve any party for any breach of this Agreement and (iii) that Sections

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

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.

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.

                   EXHIBIT A TO AGREEMENT AND PLAN OF MERGER 

                           FORM OF AFFILIATE LETTER 

                                             , 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 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: 

                                      A-52
<PAGE>
      "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, pledged or otherwise 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,

("Acquiror") and Loral Satellite Corporation, a Delaware corporation ("Merger 
Sub"). 

   WHEREAS, the parties have entered into the Merger Agreement; 

   WHEREAS, the parties to the Merger Agreement desire to amend the Merger 
Agreement to provide for the exchange by an Acquiror Subsidiary of the 
Company's capital stock for Acquiror Shares; 

   WHEREAS, pursuant to Section 9.4 of the Merger Agreement, the Merger 
Agreement may be amended with the written consent of the parties thereto. 

   NOW THEREFORE, in consideration of the foregoing premises, it is hereby 
agreed by and among, the Company, Acquiror and Merger Sub as follows: 

  (1)      Section 2.1 (c) shall be amended to read as follows: 

           "Each share of capital stock of the Company owned, directly or 
           indirectly, by Acquiror, Merger Sub or any Acquiror Subsidiary (as 
           defined in Section 5.1) shall be converted into and exchanged for 
           the right to receive such number of fully paid and nonassessable 
           shares of Surviving Corporation as necessary in order to ensure 
           that such entity's proportionate interest in the Surviving 
           Corporation immediately after the Effective Time will be equal to 
           such entity's proportionate interest in the Company immediately 
           prior to the Effective Time." 

  (2)      Unless otherwise defined herein, capitalized terms used in this 
           Amendment No. 1 to the Merger Agreement (including the Recitals 
           hereto) shall have the meanings ascribed to such terms in the 
           Merger Agreement. 

  (3)      This Amendment may be executed and delivered in one or more 
           counterparts, and by the different parties hereto in separate 
           counterparts, each of which when executed and delivered shall be 
           deemed to be an original but all of which taken together shall 
           constitute one and the same agreement. 

   IN WITNESS WHEREOF, the parties hereto have caused this Agreement and Plan 
of Merger to be executed and delivered as of the date written above.

   WHEREAS, the parties hereto desire to amend and restate the Initial 
Agreement. 

   NOW, THEREFORE, in consideration of the foregoing premises and agreements

                                  ARTICLE I 

                  GRANT OF OPTION AND EXERCISE; TRANSFER AND 
                         VOTING OF SHARES; DEBENTURES 

SECTION 1.1. GRANT OF OPTION. 

   Subject to the terms and conditions set forth herein, each Stockholder 
hereby severally and not jointly grants to Acquiror an irrevocable option 
(the "Option") to purchase all (but not less than all) of such Stockholder's 
Shares held on the date of option exercise (and to require the conversion of 
all (but not less than all) of such Stockholder's Debentures into Shares 
immediately prior to the Closing (defined 

                                      B-1
<PAGE>
in Section 1.3 below) hereunder, and upon such conversion such Shares shall 
be subject to the Option hereunder) for the number of fully paid and 
nonassessable Acquiror Shares (as adjusted pursuant to Section 2.5 of the 
Merger Agreement) equal to the number of Shares to be purchased by Acquiror 
multiplied by the Exchange Ratio (calculated using the Notice Date as if it 
were the "Closing Date" (as defined in the Merger Agreement) for purposes of 
calculating the Determination Price), together with the associated rights 
under Acquiror's Rights Agreement ("Acquiror Rights Plan") dated as of March 
27, 1996 between Acquiror and The Bank of New York, as Rights Agent 
(together, the "Purchase Price"). 

SECTION 1.2. EXERCISE OF OPTION. 

   (a) Provided that neither Acquiror nor Sub shall be in material breach of 
their respective agreements or covenants contained in the Merger Agreement, 
Acquiror may exercise the Option, in whole (but not in part) with respect to 
all of the Shares of all of the Stockholders covered hereby (but not less 
than all), at any time following the occurrence of any event described in 
Section 1.9 (a "Purchase Event"); provided that, the Option shall terminate 
and be of no further force and effect upon the earliest to occur of (i) the 
Effective Time, (ii) June 30, 1998, or (iii) termination of the Merger 
Agreement by Acquiror or Sub in accordance with the terms thereof. 

   (b) If Acquiror exercises the Option hereunder (except following 
termination of the Merger Agreement by the Company) (i) neither Acquiror nor 
Sub shall terminate the Merger Agreement under any 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 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 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

favor of the Merger, the Merger Agreement (as amended from time to time) and

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, such as a merger, consolidation or 
other business combination involving the Company or any of it Subsidiaries;

and the transactions contemplated by this Agreement. 

   (b) Each Stockholder and Acquiror severally and not jointly agrees that it 
shall not enter into any agreement or understanding the effect of which would

severally and not jointly agrees that it will, if the Board of Directors of 
the Company fails or refuses (other than as a result of breach by Acquiror or

Affiliates will not or cannot satisfy the conditions precedent thereto) to 
submit the subject transactions to the Company's stockholders, vote all 
Shares held of record or beneficially owned by it to (i) call or cause to be 
called a special meeting of stockholders of the Company (or effect a written

deliver this Agreement, to grant the Option and to consummate the transaction 
contemplated hereby. The execution and delivery of this Agreement, the 
appointment of Acquiror and Sub as such Stockholder's Proxy, the granting of 
the Option and the 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 properties is bound or affected, or (iii) result in any breach of 
or constitute 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 

                                      B-6
<PAGE>
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 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.

   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

                                 ARTICLE III 

                  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-7
<PAGE>
    (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 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 or exchange of shares, merger, consolidation, 
reorganization or other change or transaction of or by the Company, as a 
result of which shares of any class of stock, other securities, cash or other 
property shall be issued in respect of any Shares or if any Shares shall be 
changed into the same or another class of stock or other securities, then, 
upon exercise of the Option, Acquiror shall 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). 

   (b) Any dividends or other distributions (whether payable in cash, stock 
or otherwise) by Acquiror with respect to any Acquiror Shares issued 
hereunder with a record date on or after the Closing Date will belong to the 
Stockholder to which such Acquiror Shares were issued. If on or after the 
date of this Agreement there shall occur any stock dividend, stock split, 
recapitalization, combination or exchange of shares, merger, consolidation, 
reorganization or other change or transaction of or by Acquiror, as a result 
of which shares of any class of stock, other securities, cash or other 
property shall be issued in respect of any Acquiror Shares or if any Acquiror 
Shares shall be changed into the same or another class of stock or other 
securities, then, upon exercise of the Option, each Stockholder shall receive 
for the aggregate price payable to such Stockholder upon exercise of the 
Option, all such shares of stock, other securities, 

                                      B-8
<PAGE>
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 adjustment shall be made for purposes of the 
calculations set forth in this Agreement). 

                                  ARTICLE V 

                       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 

   (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, including the transfer of the 
Shares to Acquiror and the release of any and all Encumbrances with respect 
thereto.

SECTION 6.3. TRANSFER OF ACQUIROR SHARES BY BRITISH AEROSPACE HOLDINGS, INC. 

   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 

                                      B-10
<PAGE>
limitation, 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.

                                                               October 6, 1997 

Board of Directors 
Orion Network Systems, Inc. 
2440 Research Boulevard 
Rockville, Maryland 20850 

Members of the Board: 

   We understand that Orion Network Systems, Inc. ("Orion" or the "Company"), 
Loral Space & Communications Ltd. ("Loral") and Loral Satellite Corporation 
(the "Merger Subsidiary"), a wholly owned subsidiary of Loral, propose to 
enter into an Agreement and Plan of Merger, substantially in the form of the 
draft, dated as of October 6, 1997 (the "Merger Agreement"), which provides, 
among other things, for the merger (the "Merger") of Merger Subsidiary with 
and into Orion. Pursuant to the Merger, Orion will become a wholly owned 
subsidiary of Loral, and each issued and outstanding share of common stock, 
par value $0.01 per share ("Orion Common Stock"), of Orion, other than shares 
held in treasury or held by Loral or any of its affiliates, will be converted 
into the right to receive between 0.71553 and 1.07329 shares (the "Exchange 
Ratio") of common stock, par value $0.01 per share ("Loral Common Stock") of 
Loral, as more fully set forth in the Merger Agreement. In addition, pursuant 
to the Merger, each share of preferred stock, par value $0.01 per share (the 
"Preferred Stock"), of Orion, issued and outstanding immediately prior to the 
Merger, other than shares held in treasury, will be converted into the right 
to receive the number of shares of Loral Common Stock equal to the Exchange 
Ratio multiplied by the number of shares of Orion Common Stock into which 
such share of Preferred Stock was convertible immediately prior to the 
effective time of the Merger. We also understand that the Merger Agreement 
provides, under certain circumstances, that in lieu of the Merger, Loral will 
commence an Exchange Offer pursuant to which the holders of all the 
outstanding shares of Orion Common Stock and Preferred Stock will be offered 
the opportunity to exchange (the "Exchange") such shares for shares of Loral 
Common Stock on the same terms as pursuant to the Merger. The terms and 
conditions of the Merger and the Exchange are more fully set forth in the 
Merger Agreement. We further understand that approximately 2.1% of the 
outstanding shares of Orion Common Stock is currently owned by Loral and its 
affiliates. 

   You have asked for our opinion as to whether the Exchange Ratio is fair 
from a financial point of view to the holders of Orion Common Stock (other 
than Loral and affiliates) and, assuming the conversion of the Preferred 
Stock into Orion Common Stock in accordance with their terms, to the holders 
of Preferred Stock. 

   For purposes of the opinion set forth herein, we have: 

   (i) reviewed certain publicly available financial statements and other 
information of Orion, Loral and Globalstar, L.P. ("Globalstar"); 

   (ii) reviewed certain internal financial statements and other financial 
and operating data concerning Orion, Loral and Globalstar prepared by the 
respective managements of Orion, Loral and Globalstar and discussed certain 
of the foregoing with senior executives of Orion, Loral and Globalstar; 

   (iii) analyzed certain financial forecasts for Orion, Loral and Globalstar 
prepared by the respective managements of Orion, Loral and Globalstar; 

   (iv) discussed the past and current operations and financial condition and 
the prospects of Orion, Loral and Globalstar with senior executives of Orion, 
Loral and Global star; 

   (v) reviewed the reported prices and trading activity for the common stock 
of Orion, Loral and Global star; 

   (vi) compared the financial performance of Orion, Loral and Globalstar and 
the prices and trading activity of the Orion Common Stock and the common 
stock of Loral and Globalstar with that of certain other comparable 
publicly-traded companies and their securities; 

                                      C-1
<PAGE>
    (vii) reviewed the financial terms, to the extent publicly available, of 
certain comparable acquisition transactions; 

   (viii) participated in discussions and negotiations among representatives 
of Orion, Loral and certain other parties and their financial and legal 
advisors; 

   (ix) reviewed the Merger Agreement, a draft dated October 6, 1997 of the 
Principal Stockholder Agreement among Loral, Merger Subsidiary and certain 
principal stockholders of Orion, and certain related documents; and 

   (x) performed such other analyses and considered such other factors as we 
have deemed appropriate. 

   We have assumed and relied upon without independent verification the 
accuracy and completeness of the information reviewed by us for the purposes 
of this opinion. With respect to the financial forecasts, we have assumed 
they have been reasonably prepared on bases reflecting the best currently 
available estimates and judgments of the future financial performance of 
Orion, Loral and Globalstar. We have not made any independent valuation or 
appraisal of the assets or liabilities of Orion, Loral and Globalstar, nor 
have we been furnished with any such appraisals. We have relied upon, without 
independent verification, the assessment by the respective managements of 
Orion, Loral and Globalstar of each of their technologies and products, the 
timing and risks associated with the integration of Orion and Loral, and the 
validity of, and risks associated with, Orion's, Loral's and Globalstar's 
existing and future products and technologies. Our opinion is necessarily 
based on financial, economic, market and other conditions as in effect on, 
and the information made available to us as of, the date hereof. We have also 
assumed that in connection with the receipt of all necessary regulatory 
approvals for the Merger or the Exchange, no restrictions will be imposed 
that would have a material adverse effect on the contemplated benefits 
expected to be derived in the proposed Merger or Exchange. 

   We have acted as financial advisor to the Board of Directors of Orion in 
connection with this transaction and will receive a fee for our services. In 
the past, Morgan Stanley & Co. Incorporated ("Morgan Stanley") and its 
affiliates have provided financial advisory and financing services for Orion 
and have received fees for the rendering of these services. In the ordinary 
course of business, Morgan Stanley may from time to time trade in the 
securities of Orion, Loral and Globalstar for its own account, for the 
accounts of investment funds under the management of Morgan Stanley and for 
the accounts of its customers and, accordingly, may at any time hold a long 
or short position in such securities. 

   It is understood that this letter is for the information of the Board of 
Directors of Orion, except that this opinion may be included in its entirety 
in any filing made by Orion or Loral in respect of the Merger or the Exchange 
with the Securities and Exchange Commission. In addition, this opinion does 
not in any manner address the prices at which Loral Common Stock will trade 
following consummation of the Merger or the Exchange, and Morgan Stanley 
expresses no opinion or recommendation as to how the stockholders of Orion 
should vote at the stockholders' meeting held in connection with the Merger 
or whether the stockholders of Orion should tender their shares in connection 
with the Exchange, and, with respect to the holders of Preferred Stock, 
whether such holders should convert their shares of Preferred Stock into 
Orion Common Stock. 

   Based on and subject to the foregoing, we are of the opinion on the date 
hereof that the Exchange Ratio is fair from a financial point of view to the 
holders of Orion Common Stock (other than Loral and its affiliates) and, 
assuming the conversion of the Preferred Stock into Orion Common Stock in 
accordance with their terms, to the holders of Preferred Stock. 

                                          Very truly yours, 

                                          MORGAN STANLEY & CO. INCORPORATED

                   NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN 
                              (THE "AMENDMENT") 

   Orion Network Systems, Inc. (the "Company") hereby amends the terms of the 
Orion Network Systems, Inc. Non-Employee Director Stock Option Plan (the 
"Plan") as follows: 

   New Article 4.3 is added to read as follows: 

   4.3. Notwithstanding any other provisions of the Plan, including without 
limitation Section 4.2 above, upon consummation of the merger of Loral 
Satellite Corporation ("Merger Subsidiary") with and into the Company (the 
"Merger") pursuant to the Agreement and Plan of Merger, dated as of October 
7, 1997 (the "Merger Agreement"), among Orion, Loral Space & Communications 
Ltd. ("Loral") and Merger Subsidiary, a wholly owned subsidiary of Loral, as 
such Merger Agreement may be amended from time to time, all Options 
theretofore granted under the Plan shall not terminate, the Plan shall be 
assumed by Loral, all Options shall be converted into options to acquire 
shares of common stock of Loral with appropriate adjustments as to the number 
of shares and exercise prices as provided in the Merger Agreement and all 
Options shall continue in the manner and under the terms so provided. In 
addition, notwithstanding any other provisions of the Plan, immediately prior 
to consummation of the Merger (the "Pre-Merger Time"), all Options 
theretofore granted under the Plan which are not then exercisable shall 
become exercisable to the extent that such options would have become 
exercisable if the next annual meeting of the stockholders of the Corporation 
at which Directors are elected had occurred at or immediately prior to the 
Pre-Merger Time. 

                                    * * * 

   This Amendment was duly adopted and approved by the Board of Directors of 
the Corporation on December 31, 1997 effective as of December 31, 1997.

   Orion Network Systems, Inc. (the "Company") hereby amends the terms of the 
Stock Option Agreement between Orion Network Systems, Inc. and John G. Puente 
dated as of July 17, 1996 (the "Puente Option Agreement") as follows: 

   New Article 17 is added to read as follows: 

   17. Notwithstanding any other provisions of this Agreement, including 
without limitation Section 7(C) above, upon consummation of the merger of 
Loral Satellite Corporation ("Merger Subsidiary") with and into the Company 
(the "Merger") pursuant to the Agreement and Plan of Merger, dated as of 
October 7, 1997 (the "Merger Agreement"), among Orion, Loral Space & 
Communications Ltd. ("Loral") and Merger Subsidiary, a wholly owned 
subsidiary of Loral, as such Merger Agreement may be amended from time to 
time, the Option granted to John G. Puente under the Puente Option Agreement 
(the "Puente Option") shall not terminate and, instead, the Puente Option 
shall be assumed by Loral, the Puente Option shall be converted into an 
option to acquire shares of common stock of Loral with appropriate 
adjustments as to the number of shares and exercise price as provided in the 
Merger Agreement and the Puente Option shall continue in the manner and under 
the terms so provided. In addition, for the avoidance of doubt, the Company, 
through action of its Board of Directors, acknowledges and agrees that all 
conditions for the vesting of the Puente Option were satisfied as a result of 
completion of the $710 million bond financing in January 1997. 

                                    * * * 

   This Amendment was duly adopted and approved by the Board of Directors of 
the Corporation on December 31, 1997 effective as of December 31, 1997.
