- ----------
   * The issuer of the Units is a newly-formed  Delaware  corporation  presently
named Orion Newco Services,  Inc., but will become the parent holding company of
an existing public  company,  Orion Network  Systems,  Inc., and will change its
name to Orion Network Systems,  Inc., in a merger and exchange  transaction that
will  occur  prior  to or  simultaneously  with the  closing  of the sale of the
securities  registered  hereby (as described in the  registration  statement and
included  prospectus  and in a  merger  proxy  statement  that  will  be sent to
stockholders prior to the sale of the securities  registered hereby).  Since the
issuer of the Units,  on a  consolidated  basis  (through  the  existing  public
company  which will become its  wholly-owned  subsidiary),  will  succeed to and
continue the business of the existing  public  company  Orion  Network  Systems,
Inc.,  the issuer of the Units  believes  that it is more  informative  and less
confusing for potential investors and existing stockholders if this registration
statement and the prospectus included herein refer to the issuer of the Units as
Orion Network Systems, Inc.

          $ REPRESENTING       UNITS, EACH UNIT CONSISTING OF ONE  %
                      SENIOR NOTE DUE 2007 AND ONE WARRANT
                            TO PURCHASE COMMON STOCK

          $ REPRESENTING       UNITS, EACH UNIT CONSISTING OF ONE  %
                  SENIOR DISCOUNT NOTE DUE 2007 AND ONE WARRANT
                            TO PURCHASE COMMON STOCK

                                   ----------
   
Orion  Network  Systems,  Inc.  is offering  Senior  Note  Units,  each of which
consists  of one %  Senior  Note  due  2007 of the  Company  guaranteed  by each
Restricted  Subsidiary (as defined  herein) of the Company (a "Senior Note") and
one  Warrant  to  purchase  shares of  common  stock,  par value  $.01 per share
("Common  Stock") of the Company (a "Senior Note Warrant"),  and Senior Discount
Note Units, each of which consists of one % Senior Discount Note due 2007 of the
Company  guaranteed  by each  Restricted  Subsidiary  of the  Company (a "Senior
Discount Note," and together with the Senior Notes, the "Notes") and one Warrant
to  purchase  shares of Common  Stock (a "Senior  Discount  Note  Warrant,"  and
together with the Senior Note Warrants, the "Warrants"). Orion's Common Stock is
quoted on the Nasdaq National Market under the symbol "ONSI."     

Interest  on the Senior  Notes will be payable  semi-annually  in cash on and of
each year,  commencing             ,  1997.  The Senior  Discount Notes will not
accrue cash interest prior to               ,  2002.  Thereafter,  cash interest
will accrue until maturity at an annual rate of % payable  semi-annually  on and
of each year,  commencing , 2002. See "Certain  United States Federal Income Tax
Consequences."  The Notes will be redeemable,  at the Company's option, in whole
or in part, at any time on or after             , 2002 at the redemption  prices
set forth herein,  plus accrued and unpaid  interest,  if any, to the redemption
date.  The Notes will have the benefit of  unsubordinated  unsecured  guarantees
(the  "Guarantees")  by each of the Restricted  Subsidiaries of the Company (the
"Guarantors").

On the closing  date,  the Company will use a portion of the  proceeds  from the
Senior Notes to purchase a portfolio of Pledged  Securities,  consisting of U.S.
government  securities,  that  will be  pledged  as  security  for the first six
scheduled interest payments on the Senior Notes.

                                   ----------

The exercise  price for the Warrants  will be $ per share of Common  Stock.  The
shares of Common  Stock of Orion  initially  issuable  upon  exercise of all the
Warrants represent approximately % of the outstanding Common Stock of Orion on a
fully diluted basis as of the closing date.

                                   ----------

The indebtedness  evidenced by the Notes and the Guarantees will rank pari passu
in right of  payment  with all  existing  and  future  unsubordinated  unsecured
indebtedness  of the Company  and the  Guarantors,  respectively,  and senior in
right of payment to all existing  and future  subordinated  indebtedness  of the
Company and the Guarantors,  respectively.  After giving pro forma effect to the
Transactions (as defined),  as of September 30, 1996, the Company would have had
(on an  unconsolidated  basis)  $60.0  million of  indebtedness  (other than the
Notes) outstanding, all of which would have been subordinated indebtedness,  and
the  Guarantors,  collectively,  would have had $24.9  million  of  indebtedness
(other  than  the  Guarantees)  outstanding,   all  of  which  would  have  been
unsubordinated  indebtedness  ($7.2  million of which would have been secured by
the Company's satellite control facility) and no subordinated indebtedness.  The
Guarantees will be effectively  subordinated to such secured indebtedness to the
extent of the collateral therefor.

                                   ----------

                                   THE COMPANY

   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. The Company also offers high
speed Internet access and transmission  services to companies outside the United
States seeking to avoid "last mile" terrestrial connections and 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. The Company provides its services directly to customer premises using
very small aperture terminals ("VSATs").

   
   The Company commenced  operations of Orion 1, a high power Ku-band satellite,
in January 1995. As of September 30, 1996, Orion serviced 167 customers  through
304 points of service.  The Company's  customers  include Amoco Poland  Limited,
Amway Corporation,  AT&T Corp., BBC, British Telecom, CNN, Citibank, N.A., Deere
& Co., Global One, GTECH Corporation, Hungarian Broadcasting, News International
Limited, RTL Television, Pepsi-Cola International, Sprint Communications, Viacom
International Inc., Westinghouse Communications,  World Wide Television News and
Xerox Corporation,  or certain of their subsidiaries.  As of September 30, 1996,
Orion's contract  backlog was $123 million (after pro forma  adjustments for the
Exchange).  Substantially  all of Orion's  current  contracts with customers are
denominated  in U.S.  Dollars.  For the three months ended  September  1996, the
Company  generated  revenues of $12.2  million and EBITDA (as defined  below) of
$1.7 million.  For the first nine months of 1996, the Company generated revenues
of $30.0 million and EBITDA of $0.1 million.     

   The Company owns and operates the Orion 1 satellite,  which 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 ser-

                                        3

vices to and among  points in 27  European  countries,  portions  of the  United
States and a limited number of Latin American countries. Orion 2, expected to be
launched  in the  second  quarter  of  1999,  will  increase  significantly  the
Company's  pan-European  capacity  and  provide  coverage  of Central  and South
America.  Orion 3, expected to be launched in the fourth  quarter of 1998,  will
cover broad areas of the Asia Pacific  region  including  China,  Japan,  Korea,
India, Southeast Asia, Australia, New Zealand, Eastern Russia and Hawaii. In the
aggregate, the footprints of Orion 1, Orion 2 and Orion 3 will cover over 85% of
the world's population.

   The Company 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  U.S.,  (iv)  increased  size and  scope of  television
programming  distribution,  (v)  worldwide  deregulation  of  telecommunications
markets and (vi) continuing technological  advancements.  Satellites are able to
provide reliable,  high bandwidth  services anywhere in their coverage areas and
the Company  believes that it is well  positioned  to satisfy  market demand for
these services.

                               THE ORION STRATEGY

   Orion's  strategy is to  maximize  its  revenues  per  satellite  transponder
through the delivery of value-added  services to end users. To quickly establish
a  stable  base  of  revenues,   Orion  sells  transponder   capacity  to  video
broadcasters  and  telecommunications   service  providers.   However,   Orion's
long-term  strategic  focus is on value-added  private network  services,  which
include network design, VSAT installation,  support and monitoring,  in addition
to basic satellite  capacity service.  The implementation of Orion's strategy is
based on the following elements:

    o   Focus on Specialized Communications Needs of Multinational Organizations
    o   Bridge to Emerging Markets and Remote Locations
    o   End-to-End Service
    o   Global Coverage
    o   Early Market Entry
    o   Local Presence
    o   Ownership of Facilities

   FOCUS ON SPECIALIZED COMMUNICATIONS NEEDS OF MULTINATIONAL ORGANIZATIONS

   Orion  targets  the  needs  of  multinational   businesses  and  governmental
customers for customized private network communications services.  Advantages of
the Company's  satellite-based  network services include:  (i) transmission over
wide areas to multiple dispersed sites including sites in emerging markets; (ii)
interconnectivity  among all sites;  (iii) wide  bandwidth and high data speeds;
(iv)  transmission  of  data,  fax,  teleconferencing  and  voice  over the same
network; (v) high transmission reliability,  quality and security; (vi) Internet
access; and (vii) rapid  implementation,  both for the initial  installation and
for later network modifications. Due to the flexibility of the network, Orion is
able to provide companies with customized solutions to link multiple locations.

   BRIDGE TO EMERGING MARKETS AND REMOTE LOCATIONS

   Orion  targets  customers  doing  business  in  emerging  markets  and remote
locations  of  developed  markets  which  often lack the fiber optic and digital
infrastructure  required  for wide  bandwidth,  high  speed  data  applications.
Terrestrial  transmissions  in many  emerging  markets  must often pass  through
local,  poorly developed network segments before reaching the customer premises,
making it difficult to send and receive  high speed data.  In contrast,  Orion's
satellite system completely avoids such  "bottlenecks" in local network segments
by sending and receiving transmissions directly to and from customers,  avoiding
the need to interconnect with the local infrastruc-

                                        4

ture. A significant portion of Orion's private  communications network customers
transmit  high-speed  data to and from locations in Central and Eastern  Europe.
Orion 2 and Orion 3 will extend  coverage  to the  Commonwealth  of  Independent
States, Latin America and the Asia Pacific Region.

          [Document Contains A Diagram Of An Orion Customer Network
                Showing Direct Service To Customer Premises.]

   END-TO-END SERVICE

   Orion provides its services  directly to and among customer  locations  using
satellite  transmission  and VSATs  installed  at  customer  premises.  Offering
end-to-end  services and bypassing  terrestrial  infrastructure  allows Orion to
offer higher  reliability  and higher  quality  services  than some  terrestrial
facilities by bypassing multiple  telecommunications service providers and local
networks and avoiding  related toll  charges.  It also permits  Orion to install
networks more quickly than many of its competitors,  who must deal with multiple
vendors and multiple  communications  technologies.  Orion offers its  customers
one-stop  shopping.  This includes a single point of contact,  an  all-inclusive
contract and consistent quality of service throughout the network.

   GLOBAL COVERAGE

   Orion believes that providing  global coverage is a competitive  advantage in
marketing to multinational  corporations.  Orion 1 covers 34 European countries,
much of the U.S. and  portions of Canada,  Mexico and North  Africa.  Orion uses
capacity  leased from other  carriers to  supplement  its network  coverage area
(such as to areas of Russia and Latin America).  Orion estimates that when Orion
2 (with coverage of Europe,  Russia,  the eastern United States,  Latin America,
North Africa and the Middle East) and Orion 3 (with coverage of the Asia Pacific
region) are deployed,  the satellite  footprints in the aggregate  will cover an
area inhabited by over 85% of the world's population.  This coverage will enable
Orion to offer its customers a single source for service offerings and a greater
measure of network quality control than terrestrial alternatives.

   EARLY MARKET ENTRY

   Orion develops an early market presence in targeted geographic areas prior to
satellite  launch in order to build its customer base. To accomplish this, Orion
hires sales people,  develops relationships with ground operators,  and delivers
its services using leased satellite capacity. Orion employed this strategy prior
to the  commercial  operation of the Orion 1 satellite  and is pursuing the same
approach  with  Orion 2 and  Orion 3. For  example,  the  Company  is  currently
providing service in Latin America and Russia over leased satellite capacity.

                                        5

<PAGE>

   LOCAL PRESENCE
 
   Orion has arrangements with 30 local ground operators covering most countries
within the Orion 1 footprint, and is entering into additional arrangements as it
offers services in new areas.  These ground  operators are critical to providing
integrated service because they obtain necessary licenses,  install and maintain
the  customers'  networks,  provide  in-country  business  experience  and often
facilitate market entry.

   OWNERSHIP OF FACILITIES

   Orion believes it is strategically important to own its satellite facilities.
Orion  believes  that  over the  long-term  ownership  of  satellite  facilities
provides a cost  advantage over  resellers and other private  service  providers
that must  lease  satellite  capacity  to provide  services  to  customers.  The
Company's  satellite ownership enables it to control the quality and reliability
of its network solutions,  maintain the flexibility to rapidly add capacity, new
locations  and new features to its  customer  networks,  and respond  quickly to
customer requests.

                                   BACKGROUND

   The Company was formed in 1982 to pursue  authorization from the U.S. Federal
Communications Commission (the "FCC") to operate a transatlantic  communications
satellite system. Orion and seven limited partners,  British Aerospace, Com Dev,
Kingston  Communications,  Lockheed Martin CLS, Matra Hachette,  Nissho Iwai and
STET, formed International  Private Satellite Partners,  L.P. ("Orion Atlantic")
in 1991 to own and operate Orion 1. The limited partners (including the Company)
invested $90 million in Orion Atlantic and provided credit support for the Orion
1 credit facility (the "Orion 1 Credit Facility"). Concurrently with the closing
of the  Offering,  the Company  will  acquire the  remaining  interests in Orion
Atlantic  and  Orion  Atlantic  will  become a  wholly-owned  subsidiary  of the
Company.

                               RECENT DEVELOPMENTS

EXCHANGE AGREEMENT AND RELATED TRANSACTIONS

   Exchange  Agreement.  Orion  has  entered  into an  Exchange  Agreement  (the
"Exchange  Agreement")  with  all of the  existing  limited  partners  in  Orion
Atlantic  (the  "Limited  Partners").  Orion  Atlantic  was  formed as a limited
partnership to comply with  then-applicable  requirements of the FCC with regard
to foreign  ownership  and control.  However,  Orion  believes  the  partnership
structure  limited its access to the  capital  markets.  Accordingly,  under the
Exchange  Agreement,  Orion will become the owner of 100% of Orion  Atlantic and
acquire  approximately $37.5 million of obligations of Orion Atlantic to Limited
Partners  in return for the  issuance  to the  Limited  Partners  of  redeemable
convertible  preferred  stock in Orion and the release of certain credit support
obligations  of the  Limited  Partners  (the  "Exchange").  As a  result  of the
Exchange (and the OAP Acquisition  described below),  Orion will own 100% of its
significant   subsidiaries  and  will  have  greatly  simplified  its  corporate
structure. See "The Merger and The Exchange."

   $60  million   British   Aerospace  and  Matra  Marconi  Space   Investments.
Concurrently with the Offering,  $50 million of junior subordinated  convertible
debentures  (the  "Junior  Subordinated  Debentures")  will  be  purchased  by a
subsidiary of British Aerospace Public Limited Company (British Aerospace Public
Limited Company collectively with its affiliates, "British Aerospace"), who will
be the largest  beneficial  owner of Orion Common Stock as of the closing of the
Offering  (the  "British  Aerospace   Investment").   The  Junior   Subordinated
Debentures  will mature in 2012,  and will bear  interest at a rate of 8.75% per
annum to be paid  semi-annually  in arrears  solely in Orion Common  Stock.  The
Junior Subordinated Debentures will be subordinated to all other

                                        6

indebtedness of the Company,  including the Notes.  Also  concurrently  with the
Offering,  Matra  Marconi  Space  U.K.  Limited  ("Matra  Marconi  Space")  will
re-invest  in Orion  $10  million  of the $13  million  of  satellite  incentive
payments it will receive (as the Orion 1 manufacturer)  upon consummation of the
Offering.  Such  re-investment  will be in Junior  Subordinated  Debentures (the
"Matra Marconi Investment," and together with the British Aerospace  Investment,
the "Debenture Investments"). See "Description of Certain Indebtedness."

   
   Acquisition of Minority  Interest.  Orion has acquired from British Aerospace
the only outstanding  minority  interest in Orion Asia Pacific (which has rights
to certain orbital slots) for approximately  86,000 shares of Orion Common Stock
(the "OAP Acquisition").     

ORION 2 AND ORION 3 CONTRACTS

   
   Orion  2 and  Orion  3  Construction  Contracts.  Orion  has  entered  into a
satellite  procurement contract with Matra Marconi Space for Orion 2 (the "Orion
2 Satellite Contract").  Orion has entered into a satellite contract with Hughes
Space and Communications  International,  Inc. ("Hughes Space") for Orion 3 (the
"Orion  3  Satellite  Contract"),  and  commenced  construction  of  Orion  3 in
mid-December  1996.  Orion  expects  to  commence  the  construction  of Orion 2
immediately following completion of this Offering.
    

   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 unless Orion 3 commences commercial operation by June 30, 1999.

                                           will provide that on the closing date
                                           of the Offering (the "Closing Date"),
                                           the Company must  purchase and pledge
                                           to  the  Senior  Notes  trustee  (the
                                           "Trustee")  for  the  benefit  of the

                                           Securities    (consisting   of   U.S.
                                           government   obligations)   in   such
                                           amount  as will be  sufficient,  upon
                                           receipt  of  scheduled  interest  and
                                           principal     payments     of    such
                                           securities, to provide for payment in
                                           full  of  the  first  six   scheduled

                                           however,   the   precise   amount  of
                                           securities to be acquired will depend
                                           upon the interest  rate on the Senior
                                           Notes  and on market  interest  rates
                                           prevailing  on the  Closing  Date.  A

                                           interest  on the  Senior  Notes  in a
                                           timely  manner  through the first six
                                           scheduled interest payment dates will
                                           constitute  an  immediate   Event  of
                                           Default   under  the   Senior   Notes
                                           Indenture,  with  no  grace  or  cure

                                           herein,   plus   accrued  and  unpaid
                                           interest,  if any, to the  redemption

Change of Control.....................     In the event of a Change  of  Control
                                           (as defined herein), the Company will
                                           be  obligated  to  make an  offer  to
                                           purchase all  outstanding  Notes at a
                                           purchase price equal to 101% of their
                                           principal  amount (in the case of the
                                           Senior   Notes)   or  101%  of  their
                                           Accreted  Value  (in the  case of the
                                           Senior Discount Notes),  in each case
                                           plus  accrued  and  unpaid   interest
                                           thereon to the  repurchase  date. See
                                           "Description  of Notes --  Repurchase
                                           of Notes  Upon a Change of  Control."
                                           If a Change of  Control  occurs  when
                                           less  than $50  million  of the Notes
                                           remain  outstanding,  the  holders of
                                           the  Junior  Subordinated  Debentures
                                           will  have  the  right  to sell  such
                                           securities  to the Company.  However,
                                           the  Indentures  contain  a  covenant
                                           which will  effectively  prohibit the
                                           Company from honoring such right. See
                                           "Description        of        Certain

                                           September 30, 1996, the Company would

(1) Adjusted  to reflect  the pro forma  effects of the  Transactions  (see "Pro

    occurred,  in the case of  Consolidated  Statements of  Operations  Data, on
    January 1, 1995 and, in the case of  Consolidated  Balance  Sheet  Data,  on
    September 30, 1996.

(2) As required by generally accepted accounting  principles ("GAAP"),  net loss
    is  presented  before  accretion  of  preferred  stock and  preferred  stock
    dividends.  For the years  ended 1994,  1995,  1995 (pro forma) and the nine
    months ended  September  30, 1995,  1996 and 1996 (pro forma),  accretion of
    preferred stock and preferred stock dividends are $.6 million, $1.3 million,
    $9.1 million, $1.0 million, $1.0 million and $6.9 million, respectively.
    

(3) Computed on the basis  described  for net loss per common share in Note 2 to
    the Consolidated Financial Statements.

   
(4) For purposes of the ratio of earnings to fixed charges,  earnings consist of
    earnings from  continuing  operations,  plus fixed  charges,  reduced by the
    amount  of  unamortized  interest  capitalized.  Fixed  charges  consist  of
    interest on all indebtedness  (including commitment fees and amortization of
    deferred  financing  costs)  plus the portion of rent  expense  representing
    interest  (estimated to be one-third of such  expense).  For the years ended
    December 31, 1994 and 1995, and the nine months ended September 30, 1995 and
    1996,  earnings were  inadequate  to cover fixed  charges by $35.2  million,
    $28.2 million, $21.3 million and $19.8 million, respectively. On a pro forma
    basis assuming  consummation  of the  Transactions,  earnings would not have
    been  sufficient to cover fixed charges by $137.7  million and $95.8 million
    for the year ended December 31, 1995 and the nine months ended September 30,
    1996,  respectively.  A .5%  increase in the assumed  interest  rates on the
    Notes  would  result in pro forma  deficiencies  of  earnings to cover fixed
    charges of approximately $140.7 million for the year ended December 31, 1995
    and $98.0 million for the nine months ended September 30, 1996.
    

(5) Backlog  represents  future  revenues under  contract.  See "Risk Factors --
    Uncertainties Relating to Backlog."

(6) Points of  service  includes  installed  VSATs and  additional  transmission
    destinations (such as customer premises) that share a VSAT.

   
(7) "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 for the period and
    should not be considered  as an  alternative  to cash flows from  operating,
    investing or financing  activities as  determined  in accordance  with GAAP.
    EBITDA is not a  measurement  under GAAP and may not be  comparable to other
    similarly  titled  measures  of  other  companies.  Other  expense  (income)
    includes gains on sale of equipment, less the write-off of costs relating to
    an attempted  financing (the "1995 Attempted  Financing") of $3.4 million in
    the fourth quarter of 1995.

(8) Restricted and segregated cash  represents (i) the estimated  $118.8 million
    that will be placed in escrow on the Closing Date to pre-fund the payment of
    the first six  scheduled  payments of interest on the Senior  Notes and (ii)
    $178.2  million  that will be  segregated  by the  Company  and used only to
    invest in certain high quality short term investments,  to make payments for
    additional  satellites  and certain  related  costs and to pay  interest and
    principal on the Notes.  See  "Description  of Notes -- Covenants -- Funding
    for  Additional  Satellites."  The  actual  amount to be  placed in  escrow,
    reflected as restricted cash and used for such interest payments will depend
    on the market interest rates on government securities on the Closing Date.
    

(9) Represents  amounts invested by Limited  Partners (net of syndication  costs
    related to the  investments),  adjusted for such Limited  Partners' share of
    net losses.  The  interests of the Limited  Partners will be acquired by the
    Company in the Exchange.

- ----------

*   All  information  relating  to Orion 2 and  Orion 3 is  based  on  currently
    proposed satellite designs.  Such designs are not finalized and,  therefore,
    particular  features of Orion 2 and Orion 3 are subject to change,  although
    changes  are  not  expected  to  have a  material  impact  on the  operating
    specifications of the satellites.
(1) Orion  1  was  launched  on  November  29,  1994  and  commenced  commercial
    operations on January 20, 1995.
(2) Satellite  transponders  receive  signals  up from earth  stations  and then
    convert, amplify and transmit the signals back down to other earth stations.
(3) Ku-band  frequencies  are  higher  than  C-band  frequencies  and  are  used
    worldwide for commercial satellite communications.
(4) Orion has entered into a contract  with DACOM under which Orion will provide
    eight  dedicated  transponders  on  Orion  3 for  direct-to-home  television
    service and other satellite services,  provided that Orion 3 is delivered in
    orbit and fully operational by June 30, 1999.
(5) C-band frequencies minimize interference from atmospheric conditions such as
    rain.  C-band  satellites share frequencies with terrestrial based microwave
    systems  and  therefore   require  more  on-ground   coordination  to  avoid
    interference  problems and generally  are lower power,  requiring the use of
    large earth stations to receive signals. A portion of Orion 3 is designed to
    transmit  over  C-band  frequencies  since Orion 3 is to cover areas of Asia
    where satellite signals experience significant interference from rain during
    several months of the year.
(6) Bandwidth is a measure of the  transponder  resource  which  determines  the
    information carrying capacity. The actual information carrying capacity of a
    transponder  is determined by a combination of the  transponder's  bandwidth
    and  radio-frequency  ("RF") power. 
(7) Equivalent isotropic radiated power ("EIRP") is a measure of the RF power of
    each transponder.  Smaller and less expensive earth terminal antennas can be
    used with higher EIRP transponders.
(8) Total prime  power is the total  amount of power that is required to support
    all of the communications and electronics functions of the satellite.
(9) The  expected  end of a  satellite's  in-orbit  useful  life is based on the
    period during which the  satellite's  on board fuel permits  proper  station
    keeping maneuvers for the satellite. The information for Orion 1 is based on
    fuel level  estimates on February 5, 1996. The  information  for Orion 2 and
    Orion 3 is based on their expected launch dates and their expected satellite
    designs,  internal studies,  the Orion 2 Satellite  Contract and the Orion 3
    Satellite Contract.
(10)The approximate  percentages of world population covered or to be covered by
    the Orion satellites are not additive.  In the aggregate,  the footprints of
    the Orion satellites would cover over 85% of the world's population.

                                  RISK FACTORS

   In  addition  to the other  information  contained  in this  Prospectus,  the
following factors should be considered  carefully in evaluating an investment in
the Units,  which involves a high degree of risk.  Statements  contained in this
Prospectus  regarding Orion's  expectations with respect to Orion 2 and Orion 3,
related  financings,  future  operations  and  other  information,  which can be
identified by the use of forward  looking  terminology,  such as "may,"  "will,"
"expect,"  "anticipate,"  "estimate,"  or "continue" or the negative  thereof or
other  variations  thereon  or  comparable  terminology,   are  forward  looking
statements.  See "Forward  Looking  Statements." The discussions set forth below
constitute cautionary  statements  identifying important factors with respect to
such forward looking statements, including certain risks and uncertainties, that
could cause actual  results to differ  materially  from  results  referred to in
forward looking statements.  There can be no assurance that Orion's expectations
regarding any of these matters will be fulfilled.

   From its inception in 1982 through  January 20, 1995,  when Orion 1 commenced
commercial operations, Orion was a development stage company. Accordingly, Orion
has limited experience operating its business.  Orion has experienced net losses
in each fiscal year since its inception,  including a net loss of  approximately
$26.9 million and negative  EBITDA of $15.4 million  during 1995, and a net loss
of $19.8 million during the nine months ended September 30, 1996. On a pro forma
basis, giving effect to the Transactions,  the Company would have had a net loss
of $135.4 million and $92.5 million for 1995 and the nine months ended September
30,  1996,  respectively.  The  increase  in net  loss on a pro  forma  basis is
associated  with the  depreciation  on the step up in the  basis of the  Orion 1
satellite and the amortization of excess cost over fair value resulting from the
acquisition of the Limited  Partners'  partnership  interests in Orion Atlantic,
the net increase to interest  expense as a result of the  Transactions,  and the
elimination of minority  interest as a result of the Exchange.  See Notes to Pro
Forma Condensed  Consolidated  Statements of Operations.  The  implementation of
Orion's  business plan  regarding  Orion 2 and Orion 3 will require  substantial
additional  capital  for the  construction,  launch,  insurance,  financing  and
start-up costs of those satellites.  A substantial portion of these costs may be
financed with indebtedness,  which would substantially  increase interest costs.
The Company's  negative cash flow (after payments for capital  expenditures  and
interest)  has been  substantial  and net losses and negative  cash flows (after
payments for capital  expenditures  and  interest) are expected to increase over
the next few years.     

NEED FOR SUBSTANTIAL ADDITIONAL CAPITAL

   The Company  will need a  substantial  amount of capital  over the next three
years (and  possibly  thereafter)  to fund the costs of Orion 2 and Orion 3, the
purchase  of VSATs and other  capital  expenditures  and to make  various  other
payments,  such as  principal  and  interest  payments  with respect to the TT&C
Financing (as defined below), the Notes and any indebtedness incurred to finance
Orion 2 or Orion 3. The  Company's  cash flows will be  inadequate  to cover its
cash needs and the Company will seek financing from outside sources.  Sources of
additional capital may include public or private debt or equity financings.  The
Company is often involved in discussions  or  negotiations  with respect to such
potential  financings  and,  because  of  its  substantial  capital  needs,  may
consummate  any  such   financings  at  any  time.  The  Company  has  commenced
construction  of  Orion  3 and  intends  to  commence  construction  of  Orion 2
immediately  after  consummation of the Offering,  despite the fact that it does
not have any commitment  from any outside source to provide such  financing.  If
the Company is unable to obtain  financing  from outside  sources in the amounts
and at the times needed,  it could forfeit  payments made on Orion 2 and Orion 3
and its rights to Orion 2 and Orion 3 under the Orion 2 Satellite  Contract  and
Orion 3 Satellite  Contract.  Such a  forfeiture  would have a material  adverse
effect on the Company's ability to make payments on its indebtedness,  including
the Notes, and on the value of the Warrants and Common Stock.

   Expected  payments  prior to launch under the Orion 2 Satellite  Contract and
Orion 3  Satellite  Contract  and for launch  insurance  for Orion 2 and Orion 3
aggregate approximately $500 million. Of this amount, $3 million was paid in the
fourth quarter of 1996, and Orion is required to make payments

                                       15

<PAGE>
   
of  approximately  $98 million,  $350 million and $50 million in 1997,  1998 and
1999,  respectively.  These amounts include the Company's estimate regarding the
cost of  launch  insurance  (but  not  in-orbit  insurance,  which  the  Company
presently  estimates will cost  approximately $5 million to $6 million per annum
per  satellite),  which  estimate  is based upon  industry  figures but not upon
discussions with potential insurers or any commitment to provide insurance.  The
Company's actual payments could be substantially higher due to any change orders
for the  satellites,  higher than  expected  insurance  rates,  delays and other
factors. In addition,  the Company expects to expend  approximately $22 million,
$30  million and $34 million on VSATs and other  capital  expenditures  in 1997,
1998 and 1999,  respectively.  However,  there can be no  assurance  that  these
amounts  will not be  substantially  higher.  The Company  believes the costs of
VSATs and other capital  expenditures  can be financed through capital leases or
other secured financing  arrangements.  However,  the Company has not engaged in
material  discussions with potential  lenders and there can be no assurance that
such  financing can be obtained.  The Company also expects to incur an aggregate
of  approximately  $40  million  of  start-up  losses  and  financing  costs  in
connection with Orion 2 and Orion 3.     

   Under the Orion 1 Satellite  Contract,  the contractor is entitled to receive
incentive  payments  based  upon  the  performance  of Orion 1 in  orbit.  These
incentive payments could reach an aggregate of approximately $44 million through
2007,  if the  transponders  on Orion 1 continue to operate in  accordance  with
specification during that period. As of September 30, 1996 Orion had obligations
with a present  value of  approximately  $21.7 million with respect to incentive
payments.  Orion will pay $13 million in satellite incentives  concurrently with
the closing of the Offering,  of which $10 million will be  re-invested in Orion
in the Matra Marconi Investment.  Under the Orion 2 Satellite Contract, Orion is
obligated to pay $25,000 per day that the  satellite  is delivered  prior to the
scheduled delivery date.

   The  foregoing  estimates  do not  include  any  amounts  for other  possible
financing  requirements.  The  Company  may from time to time  enter  into joint
ventures and make acquisitions of complementary  businesses and is often engaged
in discussions or negotiations  with regard to such potential joint ventures and
acquisitions.  Such joint  ventures or  acquisitions  would need to be financed,
which would  increase the Company's need for  additional  capital.  In addition,
Orion intends to replace  Orion 1 at the end of its useful life  (expected to be
in October 2005). Such replacement likely will require  additional  financing if
the cash flow from Orion's  operations  is not  sufficient to fund a replacement
satellite.

   The Company's  ability to raise public equity financing may be limited by the
registration  rights it has  granted to  certain  investors.  See "--  Potential
Adverse Effect of Shares Eligible for Future Sale."

SUBSTANTIAL LEVERAGE; SECURED INDEBTEDNESS

   
   As of September 30, 1996, after giving pro forma effect to the  Transactions,
Orion would have had approximately $679 million of long-term  indebtedness,  and
will be highly leveraged. The accretion of original issue discount on the Senior
Discount Notes will substantially increase Orion's liabilities. The Company also
expects to incur  substantial  additional  amounts of indebtedness.  The Company
will deposit  approximately  $118.8  million in escrow to pre-fund the first six
scheduled  payments  of  interest  on the Senior  Notes.  However,  the  Company
ultimately will need to service the cash interest  expense on a very substantial
amount  of  indebtedness  (including  the  Notes)  with  cash  generated  by its
operations.  For 1995 and the three and nine months ended September 30, 1996 the
Company had EBITDA of $(15.4)  million,  $1.7 million and $0.1 million and, on a
pro forma basis,  giving  effect to the  Transactions,  interest  costs of $82.9
million and $64.8 million for 1995 and the nine months ended September 30, 1996,
respectively.  Interest costs will increase  substantially if, as expected,  the
Company incurs  additional  indebtedness,  as described  above under the caption
"Need for Substantial Additional Capital." The Company does not have a revolving
credit facility or other source of readily available capital.     

   The Indentures will not limit the amount of secured  indebtedness the Company
may incur to finance the acquisition of VSATs and other equipment.  However, the
Indentures  will  prohibit the Company from using Orion 1, Orion 2 or Orion 3 as
collateral for indebtedness for money borrowed. In the event of a default on the
Notes or a bankruptcy, liquidation or reorganization of the Company, the

                                       16

<PAGE>

assets pledged to secured  indebtedness will be available to satisfy obligations
of the secured  debt before such assets could be used to make any payment on the
Notes.  Accordingly,  there may only be a limited amount of assets  available to
satisfy  any  claims of the  holders of the Notes  upon an  acceleration  of the
Notes.  In  addition,  to the  extent  that  the  value  of such  collateral  is
insufficient  to satisfy  such  secured  indebtedness,  holders of such  secured
indebtedness  would be entitled to share pari passu with the Notes with  respect
to any other  assets of the Company.  As of September  30, 1996 after giving pro
forma  effect to the  Transactions,  the Company  would have had $7.2 million of
secured indebtedness on a consolidated basis (secured by the Company's satellite
control facility).

   The level of the Company's  indebtedness could have important consequences to
holders of Units, Notes or Warrants including the following:  (i) the ability of
the  Company  to obtain  any  necessary  financing  in the  future  for  capital
expenditures,  working capital,  debt service requirements or other purposes may
be  limited;  (ii)  a  substantial  portion  of the  Company's  cash  flow  from
operations,  if any,  must be  dedicated  to the  payment  of  principal  of and
interest on its indebtedness and other obligations and will not be available for
use in the Company's  business;  (iii) the Company's level of indebtedness could
limit its  flexibility in planning for, or reacting to changes in, its business;
(iv) the Company  will be more highly  leveraged  than some of its  competitors,
which may place it at a competitive  disadvantage;  and (v) the  Company's  high
degree  of  indebtedness  will  make it more  vulnerable  to a  default  and the
consequences  thereof (such as bankruptcy workout) in the event of a downturn in
its business.  See "Management's  Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital  Resources -- Current Funding
Requirements" and "Description of Certain Indebtedness."

RISKS OF SATELLITE LOSS OR REDUCED PERFORMANCE

   
   Satellite Loss or Reduced Performance.  Satellites are subject to significant
risks,  including launch failure,  damage that impairs  commercial  performance,
failure to achieve correct orbital  placement  during launch,  loss of fuel that
reduces satellite life, and satellite in-orbit risks.  Although Orion 1 has been
successfully  launched  and  is in  commercial  operation,  and  although  Orion
maintains  satellite in-orbit insurance on Orion 1, any loss in orbit or reduced
performance  of Orion 1 would  have a  material  adverse  effect  on  Orion.  In
addition,  no assurance  can be given that the launch of Orion 2 or Orion 3 will
be successful.  Although various sources of data permit  differing  conclusions,
Orion is aware of  sources  indicating  that the  historical  loss  rate for all
commercial geosynchronous satellite launches may be as high as 15%. Launch risks
vary based upon the launch  vehicle used.  The Delta III launcher to be used for
Orion 3 is new and has no significant launch history.  Even though the Delta III
is based upon earlier Delta launch  vehicles,  the new technology  used in Delta
III could affect its launch success rate. A Delta II launch vehicle  exploded on
January 17, 1997.     
   
   Orion may have to change  launch  vehicles and could be subject to delays and
higher costs of launch insurance if, for example,  one of its selected  vehicles
experiences a launch failure with respect to another  satellite.  In such event,
delays  in the  launch  of one of  Orion's  satellites  could  result  from  the
manufacturer's  need to  investigate  the  reasons for the failure of the launch
vehicle and address any design or manufacturing concerns that are identified. It
is not  possible to predict  the  duration of any such  potential  delays.  With
respect to the risk of launch failure of Orion's satellites, Orion has an option
to  purchase  an  additional  satellite  (which  may be  used  as a  replacement
satellite) to be delivered in orbit, in the case of Orion 3, within 12, 15 or 19
months (at Orion's  election) after it exercises the option,  or, in the case of
Orion 2,  within 21 1/4 months  after it  exercises  the option.  Therefore,  an
unsuccessful  launch of Orion 2 or Orion 3 would involve a delay in revenues for
at least  one  year,  and  perhaps  substantially  longer.  Any loss or delay of
revenue  from any of the  Company's  satellites  would have a  material  adverse
effect on its ability to service its indebtedness,  including the Notes, and the
value of the Warrants and the Common Stock.     

   In November 1995, one of Orion 1's components supporting nine transponders of
dedicated  capacity  serving  the  European  portion  of the  Orion 1  footprint
experienced  an anomaly  that  resulted  in a  temporary  service  interruption,
lasting  approximately  two hours.  Full service to all affected  customers  was
restored  using  redundant  equipment  on  the  satellite.   These  transponders
currently generate a majority of Orion's revenues.  Orion believes, based on the
data  received  to date by  Orion  from  its own  investigations  and  from  the
manufacturer, and based upon advice from Orion's independent engineering

                                       17

<PAGE>

consultant,  Telesat Canada, that because the redundant component is functioning
fully 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.  Furthermore,  there has been
no further effect on Orion's ability to provide services to customers.  However,
in the  event  that  the  currently  operating  component  fails,  Orion 1 would
experience a significant  loss of usable  capacity.  In such event,  while Orion
would be entitled to insurance  proceeds of approximately  $47 million and could
lease  replacement  capacity  and  function as a reseller  with  respect to such
capacity (at  substantially  reduced gross margins),  the loss of capacity would
have a material  adverse  effect on the  Company,  on its ability to service its
indebtedness,  including  the Notes,  and the value of the  Warrants  and Common
Stock.  See "Business --  Implementation  of the Orion Satellite System -- Orion
1."

   At the time of Orion's 1 delivery  from its  manufacturer,  one of the six 36
MHz  transponders  covering the United  States was not  performing in accordance
with contract  specifications  based on then-available  data. To date, Orion has
not used such transponder to provide services under any commercial contract, and
there can be no  assurance  that such  transponder  will ever be used.  Although
Orion  settled  the  matter  with the  manufacturer  for a  one-time  refund  of
approximately  $2.75  million  and monthly  payments of $7,000,  there can be no
assurance that such payments  adequately  compensated Orion for the loss of such
transponder.

   
   Limited Insurance for Satellite Launch and Operation.  The in-orbit insurance
of Orion 1 and the launch and  in-orbit  insurance  for Orion 2 and Orion 3 will
not protect the Company against business interruption, loss or delay of revenues
and similar losses and may not fully reimburse the Company for its expenditures.
In  addition,  such  insurance  includes or can be  expected to include  certain
contract terms, exclusions,  deductibles and material change conditions that are
customary in the industry.  Accordingly,  an  unsuccessful  launch of Orion 2 or
Orion  3 or any  significant  loss of  performance  with  respect  to any of its
satellites  would have a material  adverse effect on Orion,  its ability to make
payments on its  indebtedness  and the value of the Warrants  and Common  Stock.
Although  Orion intends to procure  insurance for the  construction,  launch and
insurance  costs of Orion 2 and Orion 3, Orion has not obtained  any  commitment
from insurance  underwriters to provide launch insurance for Orion 2 or Orion 3.
There can be no  assurance  that such  insurance  will be  available or that the
price of such  insurance  or the terms and  exclusions  in the actual  insurance
policy will be favorable to the Company. A failure of one of the launch vehicles
selected by Orion prior to the launch of Orion 2 or Orion 3 could  substantially
increase the cost of launch  insurance for Orion.  See "Business --  Insurance."
    

   Limited Life of Satellites. While Orion 1 is expected to have an orbital life
of approximately  10.7 years (through October 2005), and Orion 2 and Orion 3 are
expected  to  have  orbital  lives  of  approximately  13  years  and 15  years,
respectively,  there  can be no  assurance  as to the  actual  longevity  of the
satellites.  A number of factors will affect the useful life of each  satellite,
including the rate of fuel  consumption in achieving  correct orbital  placement
during  launch,  the  quality  of its  construction  and the  durability  of its
component  parts.   There  is  a  significant   possibility  that  one  or  more
transponders   on  a  satellite  may  cease  to  function  in  accordance   with
specifications  during its estimated  useful life and there is no assurance that
service could be restored through  redundant  transponders.  In addition,  while
Orion plans to replace each  satellite at the end of its useful life,  there can
be no assurance that the required  financing and  regulatory  approvals to do so
will be available.

LAUNCH OF ORION 2 AND ORION 3 SUBJECT TO SIGNIFICANT UNCERTAINTIES

   
   Cost Uncertainties.  Based on the current designs of and current construction
schedules  for  Orion 2 and  Orion 3, the  total  costs of Orion 2 and  Orion 3,
including construction,  launch, launch insurance,  financing costs and start-up
expenses,  are  presently  estimated to be  approximately  $265 million and $275
million, respectively.  These costs may increase as a result of changes that may
occur  during the  construction  of the  satellites  or if the cost of insurance
exceeds the Company's  expectations. See "Business --  Implementation  of the
Orion  Satellite  System."  There can be no  assurance  that the actual costs of
these satellites will not be materially greater than these estimates.     

                                       18

<PAGE>

   Substantial  Financing  Requirements.  Completion of Orion 2 and Orion 3 will
require substantial  additional financing beyond the funds expected to be raised
in this  Offering and the British  Aerospace  Investment.  Failure to raise such
financing  would have a material  adverse  effect on Orion,  its ability to make
payments on its indebtedness, including the Notes, and the value of the Warrants
and the Common Stock,  as discussed in more detail above under the caption "Need
for Substantial Additional Capital."

   Timing  Uncertainties.  Orion presently plans to launch Orion 2 in the second
quarter of 1999 and plans to launch Orion 3 in the fourth quarter of 1998, based
upon the construction and launch schedules set forth in the satellite contracts.
To meet these  schedules,  Orion must raise the financing needed for payments to
the satellite manufacturers,  receive certain regulatory approvals, finalize the
satellite  designs  and  take  other  necessary  steps.   Failure  to  meet  the
construction and launch schedules could increase the cost of Orion 2 or Orion 3,
requiring additional  financing,  as described above under the caption "Need for
Substantial Additional Capital." Although the Orion 2 Satellite Contract and the
Orion 3 Satellite  Contract are  fixed-price  contracts  with firm schedules for
construction,  delivery and launch,  there can be no assurance that increases in
costs  due  to  change  orders  or  delay  will  not  occur.  See  "Business  --
Implementation  of the Orion  Satellite  System." There can be no assurance that
the  launch  of  Orion 2 or Orion 3 will  take  place as  scheduled.  Delays  in
launching  satellites are quite common,  and a significant delay in the delivery
or launch of Orion 2 or Orion 3 would have a material  adverse effect on Orion's
marketing plan for such satellites,  its ability to generate revenue and service
its indebtedness,  including the Notes, and on the value of the Warrants and the
Common Stock.

   Risks of  Proceeding  With  Construction  Prior to Obtaining  all  Regulatory
Approvals for Orion 2 and Orion 3. Orion has commenced  construction  of Orion 3
and will  commence  construction  of Orion 2 prior to completion of the required
consultation with INTELSAT and EUTELSAT (as defined), receipt of final authority
from  the FCC (in the  case of  Orion  2) and  completion  of the  International
Telecommunication Union ("ITU") coordination process. Failure to obtain one more
necessary  approvals in a timely  manner  would  likely have a material  adverse
effect on the Company. See "Approvals Needed; Regulation of Industry" below.

RISKS RELATING TO POTENTIAL LACK OF MARKET ACCEPTANCE AND DEMAND; GROUND
OPERATIONS

   
   Orion's  success  will depend in part on the  continued  growth in demand for
international  private network  services,  which to date have not been a primary
focus of satellite  companies,  and on Orion's  ability to market such  services
effectively.  Marketing will be critical to Orion's success.  However, Orion has
limited  experience in marketing,  having  commenced full commercial  operations
only in 1995. Orion's marketing program until recently consisted of direct sales
using a U.S.-based sales force, and indirect sales channels,  including  Limited
Partner  sales  representatives,  for sales in Europe.  During 1996,  certain of
Orion's indirect sales channels in Europe did not meet  expectations,  and Orion
is seeking to supplement  its sales in Europe by  significantly  increasing  its
direct  sales  capabilities  in Europe,  particularly  with  respect to sales of
private network  services.  However,  there can be no assurance that this effort
will be successful.  Sales of Orion's  services  generally  involve a long-term,
complex  sales  process,  and new  contract  bookings  will vary from quarter to
quarter.  In addition,  as an early provider of  international  network services
using  VSATs,  Orion  is  subject  to  the  uncertainties  associated  with  the
development of new services, including uncertainties regarding customer interest
in and acceptance of higher data speed  communications,  the need to develop and
convince  customers  of the  attractiveness  of new  applications,  and customer
acceptance of the ability of Orion (as a new market entrant) to provide service.
In addition, Orion's operations will continue to depend significantly on Orion's
ability to provide ground  operations for private network  services using ground
operators throughout the footprint of Orion's satellites.  In the event that its
network of ground  operators is not  maintained and expanded or fails to perform
as expected, Orion's ability to offer private network services will be impaired.
See "Business -- Network Operations; Local Ground Operators."     

                                       19

<PAGE>

RISKS CONCERNING ABILITY TO MANAGE GROWTH

   The Company's future  performance  will depend,  in part, upon its ability to
manage its growth  effectively,  which will  require it to continue to implement
and improve its marketing,  operating,  financial and accounting  systems and to
expand, train and manage its employee base and manage its relationships with its
local  ground  operators.  For  example,  Orion is in the  process of seeking to
integrate  a  significant  number of newly hired  direct  sales  personnel,  and
expects the process to continue as it seeks to increase  its sales force  during
1997.  Furthermore,  the Company may from time to time enter into joint ventures
and acquire  complementary  businesses  and is often engaged in  discussions  or
negotiations with regard to such potential joint ventures and acquisitions. Such
joint  ventures and acquired  businesses  would need to be  integrated  with the
Company,  which  would  place an  additional  burden on the  Company's  internal
systems and its ability to manage its employees and its  relationships  with its
local ground operators. In addition, the Company's ability to attract new orders
is subject to  substantial  variations  from quarter to quarter.  If the Company
fails  either to expand in  accordance  with its plans or to manage  its  growth
effectively  there could be a material  adverse effect on its business,  growth,
financial  condition  and  results of  operations,  its  ability to service  its
indebtedness,  including  the Notes,  and the value of the  Warrants  and Common
Stock.

POTENTIAL ADVERSE EFFECTS OF COMPETITION

   The  international  telecommunications  industry  is highly  competitive.  In
providing  international   telecommunications   services,  Orion  competes  with
established  satellite and other transmission  facilities  providers,  including
INTELSAT, EUTELSAT, PanAmSat and consortia of major telephone carriers operating
undersea  fiber  optic  cables.   In  addition,   Orion  competes  with  certain
established  telephone  carriers,  such as AT&T, MCI,  Sprint,  British Telecom,
Cable & Wireless, Deutsche Telekom, France Telecom and Kokusai Denshin Denwa, as
well as resellers of satellite capacity, such as companies similar to Impsat, in
providing  private network  communications  services.  Many of these competitors
have  significant  competitive  advantages,   including  long-standing  customer
relationships,  close ties with regulatory authorities, control over connections
to local telephone lines and the ability to subsidize  competitive services with
revenues from services they provide as a dominant or monopoly  carrier,  and are
substantially  larger  than  Orion  and have  financial  resources,  experience,
marketing  capabilities and name recognition that are substantially greater than
those of Orion.  The Company  believes  that  competition  in emerging  markets,
particularly  with  respect to  private  network  services,  will  intensify  as
dominant and monopoly long distance providers adapt to a competitive environment
and large carriers  increase  their presence in these markets.  The Company also
believes that  competition  in more  developed  markets will  intensify as large
carriers consolidate,  enhance their international  alliances and increase their
focus on private network services.  For example,  the recently  announced merger
involving MCI and British Telecom may substantially  increase the ability of the
resulting  businesses to provide  trans-Atlantic  private network services.  The
ability of Orion to  compete  with these  organizations  will  depend in part on
Orion's  ability to price its services at a significant  discount to terrestrial
service providers,  its level of customer support and service, and the technical
advantages of its systems.

   
   The services  provided by the Company have been subject to decreasing  prices
over recent  years and this  pricing  pressure is expected to continue  (and may
accelerate) for the foreseeable  future.  Orion will need to increase its volume
of sales in order to compensate for such price  reductions.  Orion believes that
customers  will  increase  the data speeds in their  communications  networks to
support new applications, and that such upgrading of customer networks will lead
to  increased  revenues  that will  mitigate  the  effect  of price  reductions.
However,  there can be no assurance that this will occur.  In addition,  a large
portion of satellite capacity globally is currently used for video distribution.
As an increasing  portion of satellite  capacity is used for  providing  private
network  services,  prices for these  services may decline.  Compressed  digital
video ("CDV"), which substantially  increases transmission capacity per channel,
is beginning to be used for video  distribution.  As CDV becomes more prevalent,
the supply of effective video capacity could increase significantly, which could
result in lower prices.
    

                                       20

<PAGE>

   The Company is aware of a substantial  number of new  satellites  that are in
construction  or in the planning  stages.  Most of these  satellites  will cover
areas within the footprint of Orion 1 and/or the proposed  footprints of Orion 2
and Orion 3. As these new  satellites  (other than  replacement  satellites  not
significantly larger than the ones they replace) commence operations,  they will
substantially increase the capacity available for the provision of services that
compete with the Company's  services.  After a satellite  has been  successfully
delivered in orbit,  the variable cost of  transmitting  additional data via the
satellite is limited.  Accordingly,  absent a corresponding  increase in demand,
this new  capacity  can be expected to result in  significant  additional  price
reductions.  Continued price  reductions could have a material adverse effect on
Orion's  ability to service its  indebtedness,  including the Notes,  and on the
value of the Warrants and the Common Stock. See "Business -- Competition."

APPROVALS NEEDED; REGULATION OF INDUSTRY

   Telecommunications   Regulatory   Policy.   Orion  is  subject  to  the  U.S.
Communications  Act  of  1934,  as  amended  (the  "Communications   Act"),  and
regulation  by the FCC (and,  to a limited  extent,  by the U.S.  Department  of
Commerce) and by the national and local governments of other countries.  The FCC
regulates terms and conditions of communications services, including among other
things changes in control or assignment of licenses.  The business  prospects of
Orion  could be  adversely  affected by the  adoption  of new laws,  policies or
regulations,  or changes in the  interpretation or application of existing laws,
policies  or  regulations,  that modify the present  regulatory  environment  or
conditions of the licenses granted by the FCC to Orion.

   Additional  Regulatory  Approvals Needed. The launch and operation of Orion 2
and Orion 3 will require a number of additional regulatory approvals,  including
the  following:  (i)  approvals  of the FCC  (in the  case  of  Orion  2);  (ii)
completion of successful  consultations  with INTELSAT and, in the case of Orion
2, with EUTELSAT;  (iii)  satellite  "landing"  rights in countries that are not
INTELSAT  signatories or that require additional  approvals to provide satellite
or VSAT services;  and (iv) other regulatory approvals.  Obtaining the necessary
licenses and approvals  involves  significant  time and expense,  and receipt of
such   licenses  and  approvals   cannot  be  assured.   Although  the  FCC  has
conditionally  authorized  the  construction,  launch and  operation  of Orion 2
(subject to  completion  of an INTELSAT  consultation  and  required  showing of
ability to finance the  construction,  launch and  operation for one year of the
satellite,  which  requirements  generally  must  be  satisfied  for  final  FCC
authorization of all FCC satellite  licenses),  and Orion will apply for certain
other approvals for Orion 2 and Orion 3, the FCC  authorization  for Orion 2 has
not become final (since Orion has not yet satisfied the  conditions) and most of
the other requisite approvals have not yet been obtained. Failure to obtain such
approvals  would have a material  adverse  effect on Orion and on its ability to
service its indebtedness, including the Notes, and the value of the Warrants and
Common Stock. In addition,  Orion is required to obtain  approvals from numerous
national  and  local  authorities  in the  ordinary  course of its  business  in
connection with most  arrangements  for the provision of services.  Within Orion
1's  footprint,  such  approvals  generally have not been difficult for Orion to
obtain in a timely manner,  but the failure to obtain  particular  approvals has
delayed,  and in the future may delay,  the provision of services by Orion.  The
Orion 1 license  from the FCC  expires in January  2005.  Although  Orion has no
reason  to  believe  that its  licenses  will not be  renewed  (or new  licenses
obtained) at the  expiration of the license  term,  there can be no assurance of
renewal.  In addition,  Orion will need to comply with the national laws of each
country in which it provides  services.  Laws with respect to satellite services
are currently unclear in certain jurisdictions,  particularly within the Orion 3
footprint.  In certain of these  jurisdictions,  satellite  services may only be
provided via domestic  satellites.  The Company  believes  that certain of these
restrictions  may change and that it can structure its operations to comply with
the remaining  restrictions.  However, there can be no assurance in this regard.
See "Business -- Regulation."

   ITU Coordination  Process. An international  treaty to which the U.S. and the
Republic of the Marshall  Islands (through which the Company has applied for the
Orion 3 orbital slot) are parties requires ITU coordination of satellite orbital
slots.  Various  non-U.S.  governments or  telecommunications  authorities  have
commenced  coordination  procedures  pursuant to ITU  regulations  for  proposed
satellites  at  orbital  locations  and in  frequency  bands  that  are in close
proximity to those proposed for

                                       21

<PAGE>

Orion 2 and Orion 3. Existing  satellites and any proposed  satellites  that are
launched  prior to  Orion 2 and  Orion 3 will  effectively  have  priority  over
Orion's  satellites.  Orion's  proposed use for Orion 2 and Orion 3 conflicts to
some  extent  with the use or  proposed  use of  certain  existing  or  proposed
satellites.  While Orion believes that it can successfully coordinate the use of
the orbital  locations  and  frequency  bands  proposed for Orion 2 and Orion 3,
there can be no assurance that  coordination  will be achieved.  The Company has
commenced  construction  of Orion 3 and will  commence  construction  of Orion 2
promptly following completion of the Offering, which will be prior to completion
of ITU  coordination.  There can be no assurance that ITU  coordination  will be
completed. In the event that successful  coordination cannot be achieved,  Orion
may have to  modify  the  satellite  design  for  Orion 2 or Orion 3 in order to
minimize the extent of any potential interference with other proposed satellites
using those orbital locations or frequency bands. Any such  modifications  could
increase the cost or delay the launch of the satellites (if significant  changes
to the satellite are required) and may result in  limitations  on the use of one
or more  transponders  on Orion 2 or Orion 3, which  could  affect the amount of
revenue realized from such transponders.  If interference occurs with satellites
that are in close  proximity to Orion 2 or Orion 3, or with  satellites that are
subsequently launched into locations in close proximity before completion of ITU
coordination  procedures,  such interference would have an adverse effect on the
proposed  use  of  the  satellites   and  on  Orion's   business  and  financial
performance. Orion cannot predict the extent of any adverse effect on Orion from
any such occurrences. See "Business -- Orbital Slots."

UNCERTAINTIES RELATING TO BACKLOG

   The Company's  current backlog consists of a mix of large and small contracts
for private  communications  networks  and  transmission  capacity for video and
other satellite transmission services with a variety of customers. Although many
of the  Company's  customers,  especially  customers  under large and  long-term
contracts,  are large corporations with substantial  financial resources,  other
contracts are with companies that may be subject to business or financial  risks
affecting their credit worthiness.  If customers are unable or unwilling to make
required  payments,  the Company  may be required to reduce its backlog  figures
(which would result in a reduction in future revenues of the Company),  and such
reductions  could be  substantial.  In the second  quarter of 1996,  the Company
determined  that one large customer under a long-term  contract  (accounting for
backlog of approximately $19.9 million) was not likely to raise the financing to
commence its service in the near future,  and  accordingly the Company no longer
considers such contract part of its backlog. Also in the second quarter of 1996,
the Company removed from its backlog a contract with a customer  (accounting for
backlog of approximately $4.5 million) which had ceased paying for the Company's
services.  In the fourth quarter of 1996, the Company removed $10.4 million from
its  backlog  related  to  contracts  under  which  customers  failed to use the
contracted service or failed to make timely payment. Orion presently anticipates
that at least $86.4  million of its $123 million in backlog (as of September 30,
1996 after pro forma  adjustments for the Exchange) will be realized after 1997.
The Company's contracts commence and terminate on fixed dates. If the Company is
delayed in commencing service or does not provide the required service under any
particular contract, as it has occasionally done in the past, it may not be able
to  recognize  all the  revenue it  initially  includes  in  backlog  under that
contract.  In addition,  the current  backlog  contains  some  contracts for the
useful life of Orion 1; if the useful life of Orion 1 is shorter than  expected,
some portion of backlog may not be realized unless services  satisfactory to the
customer can be provided over another satellite.

TECHNOLOGICAL CHANGES

   Although  Orion  believes  that Orion 1 does employ,  and Orion 2 and Orion 3
will employ, advanced technologies, the telecommunications industry continues to
experience  substantial  technological  changes. The Company believes that there
are numerous  telecommunications  companies that are seeking ways to improve the
data  transmission  capacity of the  existing  terrestrial  infrastructure.  Any
significant  improvement of such capacity,  particularly  with respect to copper
wire, would have a material  adverse effect on Orion.  There can be no assurance
that  other  changes  will  not  adversely  affect  the  prospects  or  proposed
operations or expenses of Orion.

RISKS OF CONDUCTING INTERNATIONAL BUSINESS

   The Company's  international  service contracts are generally  denominated in
U.S.  dollars,  but it is possible that the portion of contracts  denominated in
non-U.S.  currencies will increase over time. The vast majority of the Company's
costs (including interest and principal of the Notes, other indebtedness and the
costs  for  VSATs,  Orion  2 and  Orion  3) are  denominated  in  U.S.  dollars.
Accordingly,  an  increase  in the  value  of U.S.  dollars  relative  to  other
currencies could have an adverse effect on the Company. International operations
are also  subject to certain  risks such as  changes  in  domestic  and  foreign
government regulations and telecommunication standards,  licensing requirements,
tariffs  or  taxes  and  other  trade   barriers  and   political  and  economic
instability.

DEPENDENCE OF ORION ON KEY PERSONNEL

   Orion's  business is dependent on its executive and other  officers and other
key personnel.  Orion presently does not have employment  contracts with, or key
man life insurance covering,  such key officers or other personnel.  The loss of
key  officers  or  personnel  could  have  an  adverse  effect  on  Orion.   See
"Management."

CONTROL OF ORION BY PRINCIPAL STOCKHOLDERS

   
   Executive  officers,  directors  and their  affiliates  are  expected  to own
beneficially  approximately 8.0 million shares or approximately 40% of the Orion
voting stock that will be outstanding  after the Transactions (12 million shares
or  approximately  46% of the voting  stock that will be  outstanding  after the
Transactions on a fully diluted basis), assuming the closing of the Transactions
as of January 30, 1997. As a result of their stock ownership and, in the case of
stockholders with  representation  on the Board of Directors,  the incumbency of
directors affiliated with them, such stockholders are and will continue to be in
a position to elect the Board of Directors  and thereby  control the affairs and
management of Orion.
    

RISKS RELATING TO SENIOR PREFERRED STOCK

   
   The Company has outstanding  approximately  $15.8 million  (including accrued
dividends)  of Orion Series A 8%  Cumulative  Redeemable  Convertible  Preferred
Stock (the "Series A Preferred Stock") and approximately $4.7 million (including
accrued  dividends)  of Orion  Series  B 8%  Cumulative  Redeemable  Convertible
Preferred Stock (the "Series B Preferred  Stock," and together with the Series A
Preferred  Stock,  the "Senior  Preferred  Stock").  Although  Orion expects the
holders  of the  Senior  Preferred  Stock  to  agree  not to  exercise  any such
mandatory  redemption  or  repurchase  rights  while  the  Notes  or the  Junior
Subordinated Debentures are outstanding,  such holders have the right to require
Orion to  repurchase  the  shares  of  Common  Stock  received  as a  result  of
conversion  of the Senior  Preferred  Stock upon,  among other  things,  certain
mergers, changes of control or sales of substantially all the assets of Orion at
the pro rata interest of the holders of such stock in the consideration received
or,  in the  case of  certain  fundamental  changes,  fair  market  value;  and,
beginning  in June  1999  such  holders  have  the  right  to  require  Orion to
repurchase  Senior  Preferred  Stock (and any  Common  Stock  received  upon the
conversion  thereof) at the fair market  value (in the case of Common  Stock) or
liquidation value, including accrued and unpaid dividends (in the case of Senior
Preferred  Stock). In addition,  the documents  relating to the Senior Preferred
Stock  impose  certain  covenants  on Orion,  and  failure to comply  with those
covenants  could have an adverse effect on Orion.  See  "Description  of Capital
Stock -- Preferred  Stock" and  "Description of Notes -- Covenants -- Limitation
on Restricted Payments."     

CONSEQUENCES OF ORIGINAL ISSUE DISCOUNT ON SENIOR DISCOUNT NOTES

   The Senior Discount Notes will be issued at a substantial discount from their
principal  amount.  Consequently,   purchasers  of  the  Senior  Discount  Notes
generally will be required to include amounts in gross income for federal income
tax  purposes in advance of receipt of the cash  payments to which the income is
attributable and no cash payments of interest will be made until
          , 2002.

   Moreover,  the Senior Discount Notes will constitute  "applicable  high yield
discount obligations" ("AHYDOs") if the yield to maturity of the Senior Discount
Notes exceeds the relevant applicable

                                       23

<PAGE>

federal rate (the "AFR") at the time of issue by more than 5 percentage  points.
If the Senior  Discount  Notes  constitute  AHYDOs then the Company  will not be
entitled to deduct original issue discount ("OID") accruing with respect thereto
until such amounts are actually  paid. In addition,  if the yield to maturity of
the Senior Discount Notes exceeds the AFR by more than 6 percentage points, then
such excess (i) will not be  deductible  by the Company at any time and (ii) may
be eligible for the dividends received deduction  available to corporate holders
in  certain  circumstances.  See  "Certain  United  States  Federal  Income  Tax
Consequences"  for  a  more  detailed  discussion  of  the  federal  income  tax
consequences to purchasers of the Senior Discount Notes.

   If a bankruptcy  proceeding  is commenced by or against the Company under the
United States  Bankruptcy  Code after the issuance of the Senior Discount Notes,
the claim of a holder of Senior  Discount  Notes with  respect of the  principal
amount  thereof may be limited to an amount  equal to the sum of (i) the initial
public offering price for the Senior Discount Notes and (ii) that portion of the
original  issue discount that is not deemed to constitute  "unmatured  interest"
for purposes of the United States  Bankruptcy  Code. Any original issue discount
that was not amortized as of the commencement of any such bankruptcy  proceeding
would constitute "unmatured interest."

NO PRIOR PUBLIC MARKET

   There is no existing market for the Units,  Notes or Warrants,  and there can
be no  assurance  as to the  liquidity  of any market  that may  develop for the
Units, Notes or Warrants; the ability of holders of the Units, Notes or Warrants
to sell such  securities,  and the price at which such holders  would be able to
sell such securities cannot be predicted. If such a market were to develop, such
securities  could trade at prices that might be lower than the initial  offering
price thereof depending upon many factors,  including prevailing interest rates,
the  Company's  operating  results  and  prospects  and the market  for  similar
securities. The Underwriters have advised the Company that they currently intend
to make a  market  in the  Units,  Notes  and  Warrants;  however,  they are not
obligated to do so and any market making may be discontinued at any time without
notice. The Company does not intend to apply for listing for the Units, Notes or
Warrants on any securities exchange.

LIMITATIONS ON PAYING DIVIDENDS ON COMMON STOCK

   Orion has never  paid any cash  dividends  on its  Common  Stock and does not
anticipate  paying  cash  dividends  in the  foreseeable  future.  Orion  is not
permitted to pay dividends on the Common Stock as long as the Preferred Stock is
outstanding,   subject  to  certain  limited  exceptions.  The  Indentures  will
effectively  prohibit the payment of cash  dividends on the Common Stock for the
foreseeable  future.  See "Market  Prices for Orion  Common  Stock and  Dividend
Policy."

POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

   Upon completion of the Transactions, there will be approximately 25.9 million
shares of Common Stock outstanding on a fully diluted basis,  assuming a closing
of the Transactions as of January 30, 1997.  Orion's current  stockholders  will
hold  approximately  14.5 million of these  shares,  all of which will be freely
transferable  without  restriction or further  registration under the Securities
Act, other than the 5.5 million shares held by "affiliates"  of the Company,  as
that term is defined under the Securities Act. The shares held by affiliates are
expected to be eligible for sale pursuant to Rule 144 under the Securities  Act.
The Limited  Partners,  as owners of the Series C Preferred  Stock,  and British
Aerospace  and  Matra  Marconi  Space,  as  owners  of the  Junior  Subordinated
Debentures,  will own the remaining 11.4 million of such shares of Common Stock,
which will be issuable upon conversion of such securities. All of such remaining
shares will be deemed to be  "restricted  securities" as that term is defined in
Rule 144.  However,  the Limited  Partners,  British Aerospace and Matra Marconi
Space will be granted certain shelf, demand and "piggy-back" registration rights
with respect to the Common Stock issuable to them upon  conversion,  pursuant to
which (in the case of the  Limited  Partners)  the  Company  will be required to
prepare and cause to be filed,  as soon as practicable  after 180 days following
consummation of the Merger,  a "shelf"  registration  statement which will cover
the  registration  of certain  Eligible  Registrable  Securities  (as defined to
include approximately 25% of the Common Stock issuable to the Limited

                                       24

<PAGE>

   
Partners  upon  conversion).  The Company  will also be required to file certain
additional shelf  registration  statements for the Limited Partners so that they
will be able to sell,  each quarter,  up to 25% of the Common Stock  issuable to
them upon conversion,  on a non-cumulative  basis, and certain  additional shelf
registration  statements for the holders of the Junior Subordinated  Debentures.
No predictions can be made as to the effect,  if any, that sales of Common Stock
or the availability of additional  shares of Common Stock for sale would have on
the market price of such securities. Nevertheless, the foregoing could adversely
affect the market prices of the Warrants and Common Stock and the ability of the
Company to raise equity financing. See "Shares Eligible for Future Sale."     

ANTI-TAKEOVER AND OTHER PROVISIONS OF THE CERTIFICATE OF INCORPORATION

   
   Orion's Certificate of Incorporation  includes provisions that may discourage
or prevent certain types of transactions involving an actual or potential change
in control of Orion,  including  transactions  in which the  stockholders  might
otherwise receive a premium for their shares over then current market prices. In
addition,  the  Board of  Directors  has the  authority  to fix the  rights  and
preferences of and issue shares of preferred stock, which may have the effect of
delaying  or  preventing  a change in  control  of Orion  without  action by the
stockholders. The staggered terms of the Company's Board of Directors could also
discourage any potential  acquirer.  Orion's  Certificate of Incorporation  also
permits the  redemption  of Common Stock from  stockholders  where  necessary to
protect  Orion's  regulatory  licenses.  See  "Description  of Capital  Stock --
Certain Anti-takeover  Effects." In addition,  any change of control of Orion is
subject to the prior  approval of the FCC. See "Business -- Regulation -- United
States Regulatory Restrictions -- Unauthorized Transfer of Control."

                                   THE COMPANY

   The Company was incorporated in Delaware in 1982 to pursue authorization from
the FCC to operate a  transatlantic  satellite  system and  changed  its name to
Orion Network Systems,  Inc. in January 1988. Prior to the successful  launch of
Orion 1 in  November  1994,  significant  milestones  included:  (i)  receipt of
initial conditional  authorization from the FCC for Orion 1 in 1985,  completion
of the  consultation  process  relating  to  Orion 1 with  INTELSAT  in 1989 and
receipt  of final  authorization  for  Orion 1 from  the FCC in  1991;  (ii) the
formation of Orion Atlantic and commencement of construction of Orion 1 in 1991;
and (iii) the commencement of VSAT services,  using leased capacity,  in Eastern
Europe in 1992.  In 1991,  Orion and the Limited  Partners  (plus STET, a former
limited partner) formed Orion Atlantic to finance the  construction,  launch and
operation  of two  communications  satellites.  In 1991,  the  Limited  Partners
invested, either directly or through subsidiaries, $90 million in Orion Atlantic
and entered into firm and contingent capacity leases over seven years to support
the Orion 1 Credit Facility. The combination of the equity contributions and the
Orion 1 Credit Facility fully financed Orion 1.

   Orion principally operates through subsidiaries.  Orion Atlantic, which Orion
controls  and  operates  through  its  subsidiary  Orion  Satellite  Corporation
("OrionSat"),  a  Delaware  corporation  and the sole  general  partner of Orion
Atlantic,  owns and  operates  Orion 1 and will own and  operate  Orion 2. Orion
Atlantic Europe,  Inc., a Delaware  corporation,  conducts certain operations of
Orion Atlantic in Europe. OrionNet,  Inc., a Delaware corporation  ("OrionNet"),
serves as a representative agent of Orion Atlantic for sales of network services
and ground operations in the United States, and OrionNet Finance Corporation,  a
Delaware  corporation,  conducts  certain limited VSAT financing  activities for
OrionNet.  Asia Pacific  Space and  Communications,  Ltd. and Orion Asia Pacific
Corporation,  Delaware corporations  (collectively,  "Orion Asia Pacific"), will
own and operate Orion 3. Upon  consummation of the  Transactions,  including the
Exchange  (discussed below), the Company will own, directly or indirectly,  100%
of each of the subsidiaries  described above,  each of which will be a Guarantor
with respect to the Notes. See "The Merger and the Exchange."

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

                           THE MERGER AND THE EXCHANGE

   Concurrently with  consummation of the Offering,  the Company will consummate
the Merger and the Exchange. The purposes of the Merger and the Exchange are (i)
to  consolidate  outside  investor  ownership of the Company at the Orion level,
(ii) improve the speed and efficiency of the Company's  decision  making,  (iii)
provide  Orion with 100%  ownership  of all of its material  subsidiaries,  (iv)
allow  Orion  to  pursue  its  business  plans  and  financings  for  all of its
satellites,  (v)  eliminate  approximately  $37.5 million of  obligations  Orion
Atlantic  owes to  certain  of the  Limited  Partners,  and  (vi)  increase  the
Company's overall market capitalization.

   
   Under the Exchange  Agreement,  the Limited  Partners have agreed to transfer
their limited partnership  interests in Orion Atlantic and other rights relating
thereto to the Company in exchange  (collectively,  the  "Exchange") for 123,172
shares  of a  newly  created  class  of the  Company's  Series  C 6%  Cumulative
Convertible  Redeemable  Preferred Stock (the "Series C Preferred Stock").  Upon
consummation  of the Exchange,  the Company will own all of Orion  Atlantic.  In
addition, the Company will acquire certain rights held by certain of the Limited
Partners, including certain of the Limited Partners' rights to receive repayment
of various advances  (aggregating  approximately  $37.5 million at September 30,
1996).  The  123,172  shares  of  Series C  Preferred  Stock to be issued in the
Exchange  will be  convertible  as of the  issuance  date into  approximately  7
million  shares of the  Company's  Common  Stock.  As a result of the  Exchange,
certain of the Limited  Partners will be principal  stockholders of the Company.
See  "Description  of  Capital  Stock"  and  "Principal   Stockholders"   for  a
description  of the Series C Preferred  Stock and  security  ownership  of Orion
following the Exchange.
    

   Simultaneously with the Exchange,  under an Agreement and Plan of Merger, Old
ONSI will merge (the "Merger") with a wholly owned subsidiary  ("Merger Sub") of
a newly  formed  Delaware  corporation,  New ONSI,  which  will  have  corporate
governance  documents,  management structure,  and other features  substantially
similar to those of the Company. New ONSI will be the issuer of the Units, Notes
and Warrants offered hereby.  Old ONSI will be the surviving  corporation in the
Merger and will thereby  become a wholly owned  subsidiary of New ONSI,  and the
holders of preferred  and common  stock of Old ONSI will  receive  substantially
identical preferred and common stock of New ONSI in exchange for such stock. New
ONSI  will be  re-named  Orion  Network  Systems,  Inc.  concurrently  with  the
effectiveness of the Merger. New ONSI's stockholders will have substantially the
same securities and rights as before the Merger, although their ownership of New
ONSI will be diluted by the Exchange.

   The  closing of the  Offering  is  conditioned  upon the prior or  concurrent
closing  of the  Merger  and the  Exchange.  Occurrence  of the  Merger  and the
Exchange are subject,  among other things,  to the satisfaction or waiver by the
Company and the Limited Partners of the following conditions:  (a) completion of
a refinancing of the indebtedness of Orion Atlantic  outstanding under the Orion
1 Credit  Facility among Orion  Atlantic,  the Banks named therein (the "Banks")
and Chase  Manhattan Bank (National  Association),  as Agent  ("Chase") with the
proceeds of the Offering, (b) the termination of all agreements between or among
the Banks and Chase, on the one hand, and one or more of Orion,  Orion Atlantic,
OrionSat,  Orion and the Limited  Partners and/or their  affiliates on the other
hand,  relating to the Orion 1 Credit Facility or the security or credit support
thereof,  (c) the  release  of the  Limited  Partners'  (and  their  affiliates)
existing commitments under their firm and contingent capacity leases and various
guarantees or other commitments  supporting the Orion 1 Credit Facility, (d) the
ratification  or approval and adoption by Orion  stockholders  of the Merger and
the Exchange,  and (e) the issuance of $60 million of Orion junior  subordinated
convertible debentures in the Debenture Investments.

                               USE OF PROCEEDS

   
   The  net  proceeds  of  the  Offering  to the  Company  are  estimated  to be
approximately $577 million. Other than the $118.8 million to be placed in escrow
to  pre-fund  the first six  interest  payments  on the  Senior  Notes,  the net
proceeds  will  be  used  to  repay  the  Orion  1  Credit  Facility  (including
approximately  $8 million of accrued  interest  and $7 million of interest  rate
hedge  breakage  costs related to the Orion 1 Credit  Facility),  to pay accrued
satellite incentive fees, to pay amounts owing to STET, a former limited partner
of Orion Atlantic, and for working capital and other general corporate purposes,
including $178.2 million that will be segregated by the Company and used only to
invest in certain  high quality  short term  investments,  to make  payments for
additional  satellites  and  certain  related  costs  and  to pay  interest  and
principal on the Notes. See "Certain  Transactions" and "Description of Notes --
Covenants  -- Funding for  Additional  Satellites."  The  outstanding  principal
amount  under the Orion 1 Credit  Facility  at  September  30,  1996 was  $207.7
million,  which bears  interest at 1.75% over LIBOR.  The loan under the Orion 1
Credit  Facility  is  repayable  over  seven  years  in  graduated   semi-annual
installments ranging from the $11.9 million installment paid in July 1996 to the
$22.9 million semi-annual installments due in 2001 (and thereafter).    
   
   Set forth below are the sources and uses of funds in the Transactions,  based
on a Closing Date of January 31, 1997. The amounts are approximate  with respect
to the Orion 1 Credit  Facility  and STET Note,  and will vary  depending on the
date of repayment.

(1) The Limited Partners will make guarantee payments on January 30, 1997 to the
    Banks under their capacity leases that support the Orion 1 Credit  Facility.
    As a result,  the $223 million will be used first to repay the Banks and the
    remainder will be used to repay the Limited Partners the amounts paid to the
    Banks on January 30, 1997.     

(2) Initial payments (of $15 million, through May 1997) for Orion 3 are expected
    to be made from segregated cash or cash on hand.

   
(3) Most of the $75 million of working  capital  (excluding  the $178 million of
    segregated  cash as described  above),  plus cash on hand and cash flow from
    operations,  will be used to make  payments  on Orion 2 and  Orion 3 and for
    VSATs and other capital expenditures.  The Company does not have a revolving
    credit facility or other source of readily available capital.

              PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

   As  discussed  more fully  under the caption  "The Merger and the  Exchange,"
pursuant to the Merger,  each share of Old ONSI common stock, Series A Preferred
Stock and Series B Preferred  Stock will be converted  into the right to receive
one share of Orion Common Stock, Orion Series A Preferred Stock and Orion Series
B Preferred Stock, respectively. In addition, pursuant to the Exchange, New ONSI
will issue shares of Series C Preferred Stock for the Limited  Partners' limited
partnership interests in Orion Atlantic, a consolidated  subsidiary of Orion, as
a result of which,  among other  things,  Orion will become the owner of all the
partnership  interests in Orion Atlantic.  Orion will also acquire approximately
$37.5 million of Orion Atlantic's obligations to the Limited Partners.

   The Merger will be accounted for as a reorganization of entities under common
control.  As a result,  the assets and liabilities  transferred  pursuant to the
Merger will be accounted for at historical cost in a manner similar to a pooling
of interests.  The Exchange will be accounted for as an  acquisition of minority
interests using purchase accounting.  As a result, the assets and liabilities of
Orion  Atlantic  will be  revalued  to fair value to the  extent of the  Limited
Partners'  interests acquired as a result of the Exchange.  The determination of
the fair  value of the  Series C  Preferred  Stock has been  based on a fairness
opinion issued by a major investment  banking firm dated December 10, 1996. Such
value has been allocated to Orion Atlantic's assets and liabilities based on the
estimate  of the fair market  value of the Orion 1  satellite  as of December 1,
1996 of $304  million  provided in an  appraisal  dated  December  20, 1996 from
Ascent  Communications  Advisors,  L.P., and management's estimate of fair value
for other assets and liabilities of Orion Atlantic.

   In addition to the Merger,  the Exchange and the Debenture  Investments,  the
pro forma  condensed  consolidated  balance  sheet at  September  30, 1996 gives
effect  to the  following  transactions,  which  are,  directly  or  indirectly,
conditions  precedent to the Merger, the Exchange and the Debenture  Investments
as  described  above,  as if they  took  place on that  date:  (i) the  Offering
(including the use of the net proceeds therefrom to repay indebtedness under the
Orion 1 Credit Facility and to prefund the first six scheduled interest payments
and to pay interest rate hedge breakage costs associated with the Orion 1 Credit
Facility),  (ii) the British  Aerospace  Investment,  with gross proceeds of $50
million  (and the  application  of $1  million of the  proceeds  thereof to make
initial payments under the Orion 2 Satelite Contract), (iii) the satisfaction of
$13  million  owed to Matra  Marconi  Space  through  the  Matra  Marconi  Space
Investment of $10 million and $3 million of cash,  (iv) the acquisition by Orion
of British  Aerospace's  17%  ownership of Orion Asia Pacific for  approximately
86,000  shares of Common  Stock  (v)  payments  of  approximately  $3.9  million
including accrued interest,  owed to STET, a former limited partner and (vi) the
write-off of deferred  financing fees (such  transactions  collectively with the
Merger  and  the  Exchange,   the  "Transactions").   The  pro  forma  condensed
consolidated  statements of operations  for the year ended December 31, 1995 and
the  nine  months  ended  September  30,  1996  have  been  prepared  as if  the
Transactions  took place on January 1, 1995.  The unaudited pro forma  condensed
consolidated financial statements do not purport to present the actual financial
position or results of  operations of the Company 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.

             NOTES TO PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET
                               SEPTEMBER 30, 1996
                                   (UNAUDITED)

   
1.  To reflect the estimated proceeds from the Offering of $577 million,  net of
    estimated  financing costs of approximately $20 million and costs associated
    with the issuance of the Series C Preferred Stock of $3 million. Of the $600
    million of gross proceeds from the Offering, $ million has been allocated to
    the Senior Notes,  $ million to the Senior  Discount  Notes and $ million to
    capital in excess of par value to reflect the issuance of the Warrants based
    on the  estimated  relative  fair  values of the  Senior  Notes,  the Senior
    Discount Notes and the Warrants.  The Senior Notes and Senior Discount Notes
    are assumed to bear interest at 11.875% and 13.125% per annum, respectively,
    and are due in 2007. No assurance  can be given that the value  allocated to
    the Warrants is  indicative  of the price at which the Warrants may actually
    trade. Of the proceeds from the Offering,  approximately $118.8 million will
    be placed  in an escrow  account  to fund the first six  scheduled  interest
    payments on the Senior Notes and $178.2  million will be  segregated  by the
    Company  and  used  only to  invest  in  certain  high  quality  short  term
    investments to make payments for additional  satellites and certain  related
    costs and to pay interest and principal on the Notes.  See  "Description  of
    Notes --  Covenants  -- Funding for Additional  Satellites."  Such  amounts,
    aggregating  $297 million have been  reflected as restricted  and segregated
    cash. The actual amount placed in escrow will depend on the market  interest
    rates on government securities on the Closing Date.
    

2.  To reflect the  repayment of $207.7  million  plus accrued  interest of $2.7
    million (as of September  30, 1996) under the Orion 1 Credit  Facility,  the
    write-off  of  unamortized  deferred  financing  costs of $11.2  million and
    interest  rate  hedge  breakage  costs  of $5.9  million,  and the pro  rata
    allocation  of such costs to the minority  interests of Orion  Atlantic.  At
    January 30, 1997, the aggregate principal, interest outstanding and interest
    rate swap breakage  costs under the Orion 1 Credit  Facility is estimated to
    be approximately $222 million.

3.  To reflect (i) the estimated proceeds from the British Aerospace  Investment
    of $49.8 million, net of estimated financing costs of $.2 million,  (ii) the
    initial  down  payment  of $1  million  to  Matra  Marconi  Space  to  begin
    construction  of Orion 2 and  (iii)  the  acquisition  by  Orion of  British
    Aerospace's 17% common stock interest in Orion Asia Pacific,  a consolidated
    subsidiary (for approximately  $1.2 million in Common Stock),  which will be
    completed in connection with the Transactions.

4.  To record the payment of accrued  satellite  incentive  obligations to Matra
    Hachette of $13 million, Matra Marconi Space's corresponding reinvestment of
    $10  million  in Junior  Subordinated  Debentures,  and  financing  costs of
    $50,000.

5.  To  reflect  the  repayment  of $3.5  million of  promissory  notes and $0.4
    million of accrued  interest (as of September  30, 1996)  thereon to STET, a
    former limited partner, required to be paid as a result of the Exchange. See
    "Certain Transactions."

   
6.  To reflect the effects of the Exchange Agreement,  including the acquisition
    by  Orion  of  certain  obligations  to  the  Limited  Partners  aggregating
    approximately  $37.5 million  through the exchange of the Limited  Partners'
    partnership  interests  in Orion  Atlantic  for Series C Preferred  Stock of
    Orion.  The Series C Preferred  Stock has been valued at  approximately  $94
    million based on a fairness opinion  prepared by a major investment  banking
    firm dated  December 10, 1996 using an underlying  Common Stock price of $12
    per common share less $3 million in estimated  issuance  costs.  Such amount
    has been  allocated to the  obligations  acquired and the 58.7%  interest of
    Orion Atlantic  previously  held by the exchanging  Limited  Partners.  Such
    allocation results in a step up in basis of approximately  $46.5 million, of
    which $27.8 million has been allocated to the Orion 1 satellite  based on an
    appraisal prepared by Ascent  Communications  Advisors,  L.P. estimating the
    fair value of the Orion 1 satellite to be $304 million.  The remaining  step
    up of $18.7  has been  allocated  to costs in  excess  of fair  value of net
    assets  acquired  and is included in Other  Assets in the  accompanying  Pro
    Forma  Condensed  Consolidated  Balance Sheet.  Accumulated  depreciation of
    $27.8  million  relating  to the portion of the  satellite  revalued to fair
    value has been offset against the basis of the satellite.

   Of the $600 million of gross  proceeds from the Offering,  $ million has been
   allocated to the Senior Notes,  $ million to the Senior  Discount Notes and $
   million  to capital in excess of par value to  reflect  the  issuance  of the
   Warrants based on the estimated relative fair values of the Senior Notes, the
   Senior Discount Notes and the Warrants.  The Senior Notes and Senior Discount
   Notes  are  assumed  to bear  interest  at a rate  of  11.875%  and  13.125%,
   respectively,  per annum.  A change in the interest  rate on the Notes of .5%
   would  result in a change of $3.0  million in  interest  expense for the year
   ended December 31, 1995.

              SELECTED CONSOLIDATED FINANCIAL AND OPERATIONAL DATA
                  (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, 1991, 1992, 1993, 1994 and
1995 are derived from the Company's audited consolidated  financial  statements.
The selected consolidated  statements of operations and balance sheet data as of
September 30, 1996 and for the nine months ended September 30, 1995 and 1996 are
derived from the unaudited consolidated financial statements of the Company and,
in the opinion of the Company,  include all  adjustments,  consisting  of normal
recurring  accruals,  necessary  for a fair  presentation  of such  information.
Operating  results  for  the  nine  months  ended  September  30,  1996  are not
necessarily  indicative  of the results that may be achieved for the year ending
December 31, 1996.  The pro forma  consolidated  statements  of  operations  and
balance  sheet  data  are  derived  from  the  unaudited  Pro  Forma   Condensed
Consolidated  Financial  Statements  included herein. The pro forma data are not
necessarily indicative of the results that would have been achieved nor are they
indicative  of the  Company's  future  results.  The  data  should  be  read  in
conjunction with the Pro Forma Condensed  Consolidated  Financial Statements and
the  Consolidated  Financial  Statements,  related  notes  and  other  financial
information  included  herein.  From its  inception in 1982 through  January 20,
1995,  when Orion 1 commenced  commercial  operations,  Orion was a  development
stage enterprise.  Because of Orion's exclusive  management and control of Orion
Atlantic as its sole general  partner  (subject to certain rights of approval by
the Limited Partners),  and Orion's aggregate 33 1/3% (through November 1995, 41
2/3% from December 1995 through the present) partnership interest, the financial
statements of Orion Atlantic are consolidated  with the financial  statements of
Orion.  See  "Management's  Discussion  and Analysis of Financial  Condition and
Results of Operations," "Pro Forma Condensed  Consolidated Financial Statements"
and the Consolidated Financial Statements and Notes thereto.

   (1) In 1993,  Orion  Atlantic  terminated its commitment to purchase a second
satellite  from MMS  Space  Systems,  resulting  in a  termination  charge of $5
million. See Note 3 to the Consolidated Financial Statements.

   (2) Adjusted to reflect the pro forma effects of the  Transactions  (see "Pro
Forma  Condensed  Consolidated  Financial  Statements"),  assuming  such  events
occurred,  in the case of the  Consolidated  Statements of  Operations  Data, on
January 1, 1995 and, in the case of the  Consolidated  Balance  Sheet  Data,  on
September 30, 1996.

   
   (3) As required by GAAP, net loss is presented  before accretion of preferred
stock and  preferred  stock  dividends.  For the years ended  December 31, 1991,
1992, 1993, 1994, 1995, 1995 (pro forma) and the nine months ended September 30,
1995, 1996 and 1996 (pro forma), preferred stock dividends and accretion are $0,
$0, $0, $.6 million,  $1.3 million, $9.1 million, $1.0 million, $1.0 million and
$6.9 million, respectively. See Note 2 to the Consolidated Financial Statements.

   (4) Computed on the basis  described  for net loss per common share in Note 2
to the Consolidated Financial Statements.

   
   (5) For purposes of the ratio of earnings to fixed charges,  earnings consist
of earnings from continuing operations, plus fixed charges reduced by the amount
of unamortized  interest  capitalized.  Fixed charges consist of interest on all
indebtedness  (including  commitment fees and amortization of deferred financing
costs) plus the portion of rent expense  representing  interest (estimated to be
one-third of such expense).  For the years ended December 31, 1991,  1992, 1993,
1994 and 1995, and the nine months ended  September 30, 1995 and 1996,  earnings
were  inadequate  to cover fixed charges by $2.6  million,  $8.8 million,  $24.0
million,  $35.2  million,  $28.2  million,  $21.3  million  and  $19.8  million,
respectively.  On a pro forma basis assuming  consummation of the  Transactions,
earnings would not have been sufficient to cover fixed charges by $137.7 million
and $95.8 million for the year ended December 31, 1995 and the nine months ended
September 30, 1996, respectively.  A 0.5% increase in the assumed interest rates
on the Notes would result in pro forma  deficiencies  of earnings to cover fixed
charges of approximately $140.7 million for the year ended December 31, 1995 and
$98.0 million for the nine months ended September 30, 1996.     

   (6) Backlog  represents future revenues under contract.  See "Risk Factors --
Uncertainties Relating to Backlog."

   (7) Points of service  includes  installed VSATs and additional  transmission
destinations (such as customer premises) that share a VSAT.

   (8) "EBITDA" represents earnings before minority interests,  interest income,
interest  expense,  other  expense  (income),  income  taxes,  depreciation  and

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                          AND RESULTS OF OPERATIONS

GENERAL

   Orion's principal  business is the provision of satellite  communications for
private  communications  networks  and video  distribution  and other  satellite
transmission services. From its inception in 1982 through January 20, 1995, when
Orion  1  commenced  commercial  operations,   Orion  was  a  development  stage
enterprise.  Prior to January 1995,  Orion's  efforts were devoted  primarily to
monitoring  the  construction,  launch and in-orbit  testing of Orion 1, product
development,  marketing  and sales of  interim  private  communications  network
services, raising financing and planning Orion 2 and Orion 3.

   OrionSat is the sole  general  partner in Orion  Atlantic  and Orion has a 41
2/3%  equity  interest  in Orion  Atlantic.  Orion will become the 100% owner of
Orion Atlantic upon consummation of the Exchange.

   As a result  of  Orion's  control  of Orion  Atlantic,  Orion's  consolidated
financial  statements  include  the  accounts  of Orion  Atlantic.  All of Orion
Atlantic's revenues and expenses are included in Orion's consolidated  financial
statements,  with appropriate adjustment to reflect the interests of the Limited
Partners  in Orion  Atlantic's  losses  prior to the  Exchange.  The  assets and
liabilities  reported in the consolidated  balance sheets at September 30, 1996,
December 31, 1995 and December 31, 1994 primarily pertain to Orion Atlantic.

OVERVIEW

   Orion's revenues are principally generated under three to four year contracts
for delivery of  communications  services.  Such revenues,  substantially all of
which are  generated  through  Orion  Atlantic,  are  derived  principally  from
recurring  monthly fees from its  customers,  although  many  contracts  include
initial  non-recurring  installation  and other fees. These  non-recurring  fees
generally are structured to cover the Company's  actual costs of installation of
the  customer's  site-based  equipment.  The revenues from each  contract  vary,
depending upon the type of service, amount of capacity, data handling ability of
the  network,  the  number  of VSATs  (which  generally  are  owned  by  Orion),
value-added  services  and other  factors.  Depending on the  complexity  of the
services to be provided to a customer,  the period between the date of signature
of a contract  and the  commencement  of actual  services  (and receipt of fees)
typically  ranges  from 30  days to six  months.  Substantially  all of  Orion's
contracts  are  denominated  in  U.S.  dollars,   although  some  contracts  are
denominated  in pounds  sterling,  deutschemarks,  Austrian  shillings or French
francs. See "Risk Factors -- Risks of Conducting  International Business." Orion
begins to record  revenues under its contracts upon service  commencement to the
customer.

   The services  provided by Orion have been subject to  decreasing  prices over
recent  years  and this  pricing  pressure  is  expected  to  continue  (and may
accelerate) for the foreseeable future,  particularly if, as expected,  capacity
continues to increase.  Orion will need to increase its volume of sales in order
to compensate  for such price  reductions.  Orion  believes that  customers will
increase  the data  speeds  in their  communications  networks  to  support  new
applications,  and  that  such  upgrading  of  customer  networks  will  lead to
increased  revenues that will mitigate the effect of price reductions.  However,
there can be no assurance  that this will occur.  See "Risk Factors -- Potential
Adverse Effects of  Competition."  Orion expects to continue to incur increasing
net losses and negative cash flow (after payments for capital  expenditures  and
interest) for the foreseeable future.

   Orion's direct cost of services  includes  principally  (i) costs relating to
the  installation,  maintenance  and  licensing  of VSAT earth  stations  at its
customers'  premises;  (ii) satellite  lease payments for  transponder  capacity
(generally for services outside of the Orion 1 footprint);  and (iii) associated
miscellaneous expenses.  Sales and marketing expenses consist of salaries, sales
commissions (including commissions to third party sales representatives), travel
and  promotional  expenses.  The Company has  recently  commenced a  significant
expansion  of its  marketing  program  and expects to  continue  this  expansion
through 1997. Due to the complexity of the Company's services,  and the expected
turnover  of new sales  personnel,  sales and  marketing  expense is expected to
increase   significantly  during  1997.   Engineering  and  technical  expenses,
consisting principally of personnel costs and travel, relate to TT&C,

                                39

<PAGE>



network  monitoring,   network  design  and  similar  activities.   The  Company
constructed  its TT&C  facilities to control two  satellites.  As a result,  the
Company  anticipates  a  slight  increase  in  costs  with  Orion  2 and a  more
substantial  increase in costs with Orion 3, which will  require  separate  TT&C
facilities.  General and  administrative  expenses consist of in-orbit insurance
premiums,  personnel costs other than for selling and  engineering,  information
systems,  professional  services, and occupancy costs. These costs will increase
generally as the Company's operations expand.  Specifically,  in-orbit insurance
costs will increase significantly following the launches of Orion 2 and Orion 3.
Depreciation  and  amortization  expenses result mainly from the depreciation of
the Orion 1 satellite,  VSATs and the related equipment to service the expansion
of the private network communication  services business (see Note 2 of the Notes
to Consolidated  Financial Statements) and will increase substantially after the
launch  of Orion 2 and  Orion 3.  Interest  income is  primarily  the  result of
interest  earned  on  the  proceeds  from  Orion's  private  and  public  equity
offerings.  Interest  costs  will  increase  substantially  as a  result  of the
Offering and will  increase  again after  additional  financing  for Orion 2 and
Orion 3 is obtained. Such financing will be required substantially in advance of
the  anticipated  revenues  from Orion 2 or Orion 3.  Orion's  costs (other than
sales  commissions)  generally  do not vary  substantially  with the  amount  of
revenue from the Orion 1 satellite.

RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO THE NINE MONTHS ENDED
SEPTEMBER 30, 1995

   
   Revenue. Total revenue for the nine months ended September 30, 1996 was $30.0
million,  compared to $13.9  million for the same period in 1995, an increase of
116%,   resulting  from  increased  volume  of  sales.   Revenues  from  private
communications  network services were $11.8 million for the first nine months of
1996 compared to $5.5 million for the  comparable  period in 1995, as the number
of points of  service  increased  to 304 as of  September  30,  1996 from 124 at
September  30,  1995.  Revenues  from  video  distribution  and other  satellite
transmission  services  were $18.2  million  for the first  nine  months of 1996
compared  to  $8.4  million  for  the  same  period  in  1995  resulting  from a
substantial increase in customers for these services in 1996.
    

OPERATING EXPENSES

   Direct  expenses.  Direct  expenses for the nine months ended  September  30,
1996,  were $4.3 million  compared to $10.0 million for the same period in 1995.
The decrease of $5.7 million, or 57%, was primarily attributable to accruals for
satellite incentive  obligations owed by Orion to the contractor under the Orion
1 Satellite Contract during the initial satellite deployment period from January
20, 1995 through June 30, 1995. The Company capitalized the present value of the
remaining  satellite  incentive   obligation  of  approximately  $14.8  million,
effective  July 1, 1995, as part of the cost of the  satellite.  As of September
30, 1996,  Orion had  obligations  with a present value of  approximately  $21.7
million with respect to satellite incentives.

   Sales and marketing expenses.  Sales and marketing expenses were $7.8 million
for the nine months ended September 30, 1996, as compared to $5.9 million in the
same  period  of  1995.  The  increase  of  $1.9  million,  or 32% is  primarily
attributable to sales  commissions,  third party sales  representative  fees and
ground operator fees  associated  with the growth in the private  communications
network service business.

   Engineering and technical  expenses.  Engineering and technical expenses were
$6.3 million in the nine months ended  September  30, 1996,  as compared to $6.0
million for the  comparable  period in 1995.  The  increase  was due to customer
engineering functions in support of network services.

   General and administrative expenses. General and administrative expenses were
$11.5  million for the nine months ended  September  30, 1996,  compared to $7.2
million for the period ended  September 30, 1995.  The increase of $4.3 million,
or 60%, for the nine months ended  September  30, 1996 was  primarily due to the
inclusion of the cost of in-orbit  life  insurance  for the entire period during
1996. The policy became effective in May 1995.

                                40

<PAGE>


   Depreciation and amortization.  Depreciation and amortization expense for the
nine months  ended  September  30, 1996 was $26.4  million,  an increase of $4.1
million,  or 18%,  over the same period in 1995.  The  increase  is  primarily a
result from  depreciation  of VSATs and other  ground  equipment  to service the
expansion of the private network services business and depreciation of the Orion
1 satellite, which was placed in service January 20, 1995.

   Interest.  Interest  income  was  $1.8  million  for the  nine  months  ended
September 30, 1996, compared to $1.1 million for the nine months ended September
30, 1995. The increase in interest income ($0.7 million or 64%) during the first
three quarters of 1996 is primarily a result of interest  earned on the proceeds
from the Company's initial public offering in August 1995. Interest expense, net
of capitalized  interest,  was $20.2 million for the nine months ended September
30,  1996,  compared to $17.1  million for the  comparable  period in 1995.  The
increase in interest expense of $3.1 million in the first three quarters of 1996
is attributable  to expensing  interest  (including  commitment  fees,  interest
accretion  associated  with  the  Orion 1  satellite  incentive  obligation  and
amortization  of deferred  financing  costs) from the in-service date of Orion 1
and the  impact  of an  interest  rate  cap  agreement  in  1996.  Prior  to the
in-service date of Orion 1,  substantially all interest expense was capitalized.
Interest expense will substantially increase as a result of the Offering.

   Net Loss. The Company incurred a net loss of $19.8 million, compared to a net
loss of $20.0  million for the nine months  ended  September  30, 1996 and 1995,
respectively,  after deduction of the limited partners' and minority  interests'
share in the Company's  losses before  minority  interests' of $24.8 million and
$33.4 million,  respectively.  Net loss is expected to increase substantially in
subsequent  periods as a result of interest expense on the Notes and elimination
of the minority interests in Orion Atlantic.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO THE YEAR ENDED DECEMBER 31, 1994

   Revenue. Services revenue for 1995 was $22.3 million compared to $3.4 million
for 1994.  Revenues  from private  communications  network  services  were $10.0
million from 72 customers in 1995 and $3.4 million from 18 customers in 1994, as
the  number  of sites  in  service  increased  to 143  from  53.  Revenues  from
transmission  capacity and video distribution services were $12.3 million during
1995.  There  were no  revenues  from these  services  during  1994,  as Orion 1
commenced operations on January 20, 1995.

OPERATING EXPENSES

   Direct expenses.  Direct expenses were $10.5 million and $3.5 million in 1995
and 1994,  respectively.  The increase of $7.0 million,  or 199%,  was primarily
attributable to accruals for satellite  incentives  during 1995,  which were not
applicable  prior to launch in November 1994,  costs  associated  with equipment
sales ($2.5 million in 1995, $0 in 1994), and installation and maintenance costs
in connection  with higher  volumes of customer  sites placed in service  during
1995  ($1.3  million  in 1995,  $0.5  million  in 1994).  These  increases  were
partially  offset  by a  reduction  in  leased  transponder  capacity  costs  as
customers were  transferred  from leased capacity to Orion 1. No equipment sales
occurred during 1994.

   Sales and marketing expenses.  Sales and marketing expenses were $8.6 million
in 1995,  as compared to $5.9  million in 1994,  an increase of $2.7  million or
47%. The increase is due to the hiring of additional sales personnel,  increased
advertising and promotion expenses associated with increased sales and equipment
sales commissions.

   Engineering and technical  expenses.  Engineering and technical expenses were
$8.5 million in 1995,  as compared to $3.0 million for 1994, an increase of $5.5
million or  approximately  184%.  The  increase  is  attributable  to  increased
staffing  requirements  related to control and operation of the  satellite,  and
customer  engineering  functions  in support  of the  expansion  of the  network
services business.

   General and administrative expenses. General and administrative expenses were
$10.1 million for 1995  compared to $5.1 million for 1994.  The increase of $5.0
million or 99% was primarily due to the cost of in-orbit  insurance for Orion 1,
beginning in May 1995, and other costs  associated with Orion's  commencement of
full commercial operations.

                                41

<PAGE>



   Depreciation  and  amortization.  Depreciation  and  amortization  was  $31.4
million in 1995, an increase of $29.7  million,  as compared to $1.7 million for
1994. The increase  primarily  resulted from the commencement of depreciation of
Orion 1 upon being placed in service January 20, 1995.

   Interest. Interest income was $1.9 million for 1995, compared to $0.4 million
for the prior year.  The increase in interest  income during 1995 is primarily a
result of interest  earned on proceeds from Orion's  initial public  offering in
August 1995. Interest expense, net of capitalized interest, increased from $0.06
million for 1994 to $24.7 million for 1995. The increase in interest  expense in
1995 is  attributable  to  expensing  interest  (including  commitment  fees and
amortization of deferred  financing  costs) from the in-service date of Orion 1.
Prior to that date,  substantially  all interest expense was capitalized as part
of the cost of Orion 1.

   Other.  Other expenses of $3.4 million for the  year-ended  December 31, 1995
are  primarily  related to costs  incurred in connection  with Orion  Atlantic's
plans to raise  financing  for Orion 2, which  plans were  deferred  in November
1995.

   Net loss.  The Company  incurred a net loss of $26.9 million and $8.0 million
for 1995 and 1994,  respectively,  after deduction of the Limited  Partners' and
minority  interests'  share in the  Company's  results  of  operations  of $46.1
million and $7.4 million, respectively.

YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993

   Revenue.  Services  revenue  for the year ended  December  31,  1994 was $3.4
million  compared to $2.0  million for the year ended  December  31,  1993.  The
increased  revenue  reflects  an  increase  in the  number  of  private  network
customers from 12 in 1993 to 18 in 1994.

OPERATING EXPENSES

   Direct  expenses.  Direct  expenses were $3.5 million and $2.6 million in the
years ended December 31, 1994 and 1993, respectively.  Direct expenses increased
$0.9 million or 32% which was primarily  attributable  to the increased  revenue
generated by private network services.

   Sales and marketing expenses.  Sales and marketing expenses were $5.9 million
in the year  ended  December  31,  1994,  as  compared  to $1.9  million in 1993
primarily  due to the Company's  increased  selling  efforts in private  network
services.

   Engineering and technical  expenses.  Engineering and technical expenses were
$3.0 million in the year ended  December  31, 1994,  as compared to $1.8 million
for the year  ended  December  31,  1993.  Engineering  and  technical  services
increased  $1.2 million due to the  increased  support  requirements  of private
network services.

   
   General and administrative expenses. General and administrative expenses were
$5.1 million for the year ended  December 31, 1994  compared to $4.7 million for
the year ended  December 31, 1993.  Orion  Atlantic  entered into  interest rate
hedging arrangements which fixed the maximum interest rate through November 1995
at 11.54%.  Thereafter,  an interest  cap  agreement  is in place  relating to a
notional amount declining every nine months from $150 million effective November
30, 1993. General and administrative expenses increased $0.4 million principally
due to the increased staffing  requirements of the Company's  management team in
anticipation of higher operating levels.

   Interest.  During the year ended  December 31,  1994,  Orion  incurred  $27.0
million  of  interest  costs  (including  commitment  fees and  amortization  of
deferred financing costs) compared to $16.3 million for the comparable period in
1993,  substantially  all of which was capitalized.  The increase in interest is
attributable to additional borrowings related to the construction of Orion 1 and
subordinated borrowings beginning in late 1993 from the Limited Partners to fund
the development of the Orion Atlantic network services business.     

   Other.  Other income was $0.05  million in the year ended  December 31, 1994,
compared to expense of $4.9 million for the year ended  December  31, 1993.  The
increase  in other  income is  related to the April  1993  termination  by Orion
Atlantic of its commitment to purchase a second satellite from Space

                                42

<PAGE>



Systems (due to a reassessment of the satellite design and target markets) which
resulted  in the  forfeiture  of $5.0  million  which  was  then  expensed  as a
termination charge.

   Net loss.  The Company  incurred  net losses of $8.0 million and $7.9 million
for the years ended December 31, 1994 and 1993,  respectively,  after  deducting
the  Limited  Partners'  and  minority  interests'  share in Orion's  results of
operations of $7.4 million and $7.8 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES

   Funding to date.  Orion has required  significant  capital for  operating and
investing  activities  in  the  development  of  its  business,  and  will  need
significant  additional  capital  in the  future to  develop  fully  its  global
satellite  communications  system.  The  Company's  funding  has  been  provided
primarily by the sale of equity  securities,  including  the  completion  of its
initial public offering in August 1995 which  generated  proceeds to the Company
of approximately $52 million (net of underwriting discounts), bank loans, vendor
financing,  lease  arrangements and short-term  loans from its investors.  As of
September 30, 1996,  Orion had a working capital  deficiency of $5.7 million and
the net cash used in operations for the nine months ended September 30, 1995 and
1996, was $30.4 million and $25.0 million, respectively.

   Funding for the  construction and launch of the Orion 1 satellite and related
facilities  was fully  committed  through $90 million of equity from the limited
partners of Orion  Atlantic,  an  aggregate  of $251  million  under the Orion 1
Credit  Facility  and  approximately  $11 million  under other debt  facilities,
dedicated  primarily to the  construction  of the TT&C facility,  which is being
used to control Orion 1.

   At  September  30,  1996,  the  Company  had   outstanding   indebtedness  of
approximately  $7.2  million  under a seven year term loan  provided  by General
Electric Capital Corporation ("GECC") for the TT&C facility, which is secured by
the  TT&C  facility  and  various  assets  relating  thereto.  Additionally,  at
September  30, 1996 the Company had  obligations  with a present  value of $21.7
million, which are payable to the manufacturer of Orion 1 through 2006 (of which
$13 million will be paid in cash on the Closing Date,  $10 million of which will
be reinvested in the Junior Subordinated Debentures) and $8.0 million payable to
a  former  partner  in  Orion  Atlantic  through  1997.  Of this  $8.0  million,
approximately  $3.5  million  (plus  interest  of  approximately  $500,000 as of
January 30, 1997) will be paid with proceeds of the Offering.

   Current Funding  Requirements.  The Company will need a substantial amount of
capital over the next three years (and possibly thereafter) to fund the costs of
Orion 2 and Orion 3, the purchase of VSATs and other capital expenditures and to
make various  other  payments,  such as principal  and  interest  payments  with
respect to the TT&C Financing,  and any indebtedness incurred to finance Orion 2
or Orion 3. The Company's cash flows will be inadequate to cover its cash needs,
and the Company will seek financing from outside  sources.  The Company does not
have a revolving credit facility or other source of readily  available  capital.
Sources of  additional  capital  may  include  public or private  debt or equity
financings.  The Company is often involved in discussions or  negotiations  with
respect to such potential  financings and,  because of its  substantial  capital
needs,  may consummate any such financing at any time. The Company has commenced
construction  of  Orion  3 and  intends  to  commence  construction  of  Orion 2
immediately  after  consummation of the Offering,  despite the fact that it does
not have any  commitment  from any  outside  source to  provide  the  additional
financing  necessary to complete the construction of Orion 2 and Orion 3. If the
Company is unable to obtain financing from outside sources in the amounts and at
the times needed,  it could forfeit payments made on Orion 2 and Orion 3 and its
rights to Orion 2 and Orion 3 under the Orion 2 Satellite  Contract  and Orion 3
Satellite Contract and there would be a material adverse effect on the Company's
ability to make payments on its indebtedness, including the Notes, and the value
of the Warrants and Common Stock.

   Expected  payments  prior to launch under the Orion 2 Satellite  Contract and
Orion 3  Satellite  Contract  and for launch  insurance  for Orion 2 and Orion 3
aggregate  approximately $500 million. In addition to the $3 million paid in the
fourth quarter of 1996,  Orion will need to make payments of  approximately  $98
million,  $350  million  and $50 million in 1997,  1998 and 1999,  respectively.
These  amounts  include  the  Company's  estimate  regarding  the cost of launch
insurance (but not in-orbit  insurance,  which the Company  presently  estimates
will cost approximately $5 million to $6 million per annum

                                43

<PAGE>


   
per  satellite),  although  the Company has not had  material  discussions  with
potential insurers and has not received any commitment to provide insurance. The
Company's actual payments could be substantially higher due to any change orders
for the satellites,  insurance rates, delays and other factors. In addition, the
Company expects to expend approximately $22 million, $30 million and $34 million
on VSATs and other capital  expenditures in 1997,  1998 and 1999,  respectively.
The Company  believes these VSAT and other capital  expenditures can be financed
through capital leases or other secured  financing  arrangements.  However,  the
Company has not engaged in material discussions with potential lenders and there
can be no assurance that such financing can be obtained.     

   Under the Orion 1 Satellite  Contract,  the contractor is entitled to receive
incentive  payments  based  upon  the  performance  of Orion 1 in  orbit.  These
incentive payments could reach an aggregate of approximately $44 million through
2007,  if the  transponders  on Orion 1 continue to operate in  accordance  with
specification during that period. As of September 30, 1996 Orion had obligations
with a present  value of  approximately  $21.7 million with respect to incentive
payments.   Orion  will  pay  $13  million  in  satellite  incentives  following
completion of the Offering,  of which $10 million will be  re-invested in Junior
Subordinated Debentures of Orion in the Matra Marconi Investment.

   The  foregoing  estimates  do not  include  any  amounts  for other  possible
financing  requirements.  The  Company  may from time to time  enter  into joint
ventures and make acquisitions of complimentary  businesses and is often engaged
in discussions or negotiations  with regard to such potential joint ventures and
acquisitions.  Such joint  ventures or  acquisitions  would need to be financed,
which would  increase the Company's need for  additional  capital.  In addition,
Orion intends to replace  Orion 1 at the end of its useful life  (expected to be
in October 2005). Such replacement likely will require  additional  financing if
the cash flow from Orion's  operations  is not  sufficient to fund a replacement
satellite.  See "Risk Factors -- Need for  Substantial  Additional  Capital" and
"Risk  Factors  --  Launch  of  Orion  2 and  Orion  3  Subject  to  Significant
Uncertainties  --  Substantial  Financing  Requirements;   Risks  of  Commencing
Construction Prior to Completing Financing."

TAXES

   As of December 31,  1995,  Orion had net  operating  loss  carryforwards  for
federal tax purposes of  approximately  $51.2  million.  The ability of Orion to
benefit from net operating losses for federal income tax purposes will depend on
a number of factors, including whether Orion has sufficient income from which to
deduct  the  losses,  limitations  that may arise as a result of  changes in the
ownership of Orion, including as a result of the Transactions and other factors,
and  certain  other  limitations  which may  significantly  reduce the  economic
benefit of those losses to Orion.  Due to  uncertainty  regarding its ability to
realize the benefits of such net operating loss  carryforwards,  the Company has
established a valuation  allowance for the full amount of its net operating loss
carryforwards.  Of Orion's net operating losses, approximately $31.2 million was
incurred by Orion Atlantic and allocated to Orion.  Orion Atlantic is structured
as a partnership  for U.S.  income tax  purposes.  As a result,  Orion  Atlantic
itself generally should not be subject to federal income taxation.  Instead, the
partners of Orion Atlantic, including Orion and OrionSat, will separately report
their allocable shares of Orion Atlantic's net income,  loss, gain,  deductions,
and credits,  as determined  under the allocation  provisions of the Partnership
Agreement. Orion Atlantic may, however, be subject to income tax on a portion of
its income in certain  states and other  countries  in which it has  operations.
Under the  Partnership  Agreement,  the  first $20  million  of any  losses  was
allocated to OrionSat,  and any losses in excess of that amount  generally  have
been allocated to the partners,  including Orion and OrionSat,  in proportion to
their  respective  percentage  interests.  Subsequent  to  consummation  of  the
Exchange, all losses will be allocated to Orion.

EFFECT OF INFLATION

   
   Orion believes that inflation has not had a material effect on the results of
operations to date.

EFFECT OF RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS

   In  March  1995,  the FASB  issued  Statement  No.  121,  Accounting  for the
Impairment of  Long-Lived  Assets and for  Long-Lived  Assets to be Disposed Of,
which  requires  impairment  losses to be recorded on long-lived  assets used in
operations when indicators of impairment are present and the  undiscounted  cash
flows  estimated  to be  generated  by those  assets  are less than the  assets'
carrying amount.  Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. Orion  adopted  Statement No. 121 in
the first  quarter  of 1996.  The effect of  adoption  was not  material  to its
financial condition or results of operations.

   In October  1995,  the FASB issued  Statement No. 123,  Accounting  for Stock
Based  Compensation,  which is effective for awards after January 1, 1996. Orion
has elected to continue to follow  Accounting  Principles  Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related  Interpretations
in  accounting  for  its  employee  stock  based  award  programs,  because  the
alternative  fair value  accounting  provided for under FASB  Statement  No. 123
requires  use of option  valuation  models  that were not  developed  for use in
valuing  employee  stock  options.  Under APB 25, when the exercise price of the
employee  award equals the market price of the  underlying  stock on the date of
grant, as has been the case  historically  with Orion's awards,  no compensation
expense is recognized.

                                   BUSINESS

OVERVIEW


   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. The Company also offers high
speed Internet access and transmission  services to companies outside the United
States seeking to avoid "last mile" terrestrial connections and 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. The Company provides its services directly to customer premises using
VSATs.

   The Company  commenced  operations of Orion 1, a high power Ku-band satellite
in January 1995. As of September 30, 1996, Orion serviced 167 customers  through
304 points of service.  The Company's  customers  include Amoco Poland  Limited,
Amway Corporation,  AT&T Corp., BBC, British Telecom, CNN, Citibank, N.A., Deere
& Co., Global One, GTECH Corporation, Hungarian Broadcasting, News International
Limited, RTL Television, Pepsi-Cola International, Sprint Communications, Viacom
International Inc., Westinghouse Communications,  World Wide Television News and
Xerox Corporation,  or certain of their subsidiaries.  As of September 30, 1996,
Orion's contract  backlog was $123 million (after pro forma  adjustments for the
Exchange).  Substantially  all of Orion's  current  contracts with customers are
denominated in U.S. Dollars.  For the three months ended September 30, 1996, the
Company generated revenues of $12.2 million and had a loss from operations,  net
loss and EBITDA (as defined  below) of $(7.2)  million,  $(5.8) million and $1.7
million,  respectively. For the first nine months of 1996, the Company generated
revenues of $30.0  million and had a loss from  operations,  net loss,  net cash
used in  operating  actives  and EBITDA of  $(26.3)  million,  $(19.8)  million,
$(25.0) million and $0.1 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 for the  period and should not be  considered  as an  alternative  to cash
flows from  operating,  investing  or  financing  activities  as  determined  in
accordance  with  GAAP.  EBITDA is not a  measurement  under GAAP and may not be
comparable to other similarly titled measures of other companies.

   The Company 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  U.S.,  (iv)  increased  size and  scope of  television
programming  distribution,  (v)  worldwide  deregulation  of  telecommunications
markets and (vi) continuing technological  advancements.  Satellites are able to
provide reliable,  high bandwidth services anywhere in their coverage areas, and
the Company  believes that it is well  positioned  to satisfy  market demand for
these services. 

THE ORION SATELLITE SYSTEM


   The  Company  launched  Orion  1, a high  power  satellite  with  34  Ku-band
transponders,  in  November  of 1994.  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.

   The Company has recently  signed a contract  with Matra Marconi Space for the
construction  and launch of Orion 2. Orion 2 will expand the Company's  European
coverage  and extend  coverage to portions of the  Commonwealth  of  Independent
States, Latin America and the Middle East, as shown in 

                                       46

<PAGE>



more   detail  in  the   footprint   set  forth  below  under  the  caption  "--
Implementation  of the Orion Satellite System -- Orion 2." Orion 2 will increase
significantly  the  Company's  pan-European  capacity,  currently  the  area  of
strongest  demand for the Company's  services.  The Company  recently  commenced
selling  services in certain areas of Latin America.  Orion 2 is scheduled to be
launched in the second quarter of 1999.

   
   The Company has recently entered into a satellite  procurement  contract with
Hughes  Space  for the  construction  and  launch  of Orion 3 and has  commenced
construction  of Orion 3. Orion 3 will  cover  broad  areas of the Asia  Pacific
region including China,  Japan,  Korea, India,  Southeast Asia,  Australia,  New
Zealand, Eastern Russia and Hawaii, as shown in more detail in the footprint set
forth below under the caption "--  Implementation  of the Orion Satellite System
- -- Orion 3." Orion 3's  footprint  will  provide the Company with the ability to
redistribute  programming  from the United States via Hawaii to most of the Asia
Pacific region.  The Company has already taken a number of steps to establish an
early market  presence in Asia,  and has entered  into an $89 million  lease for
eight of Orion 3's 43  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.  Maps of the footprints of Orion 1, Orion 2
and Orion 3 are set forth below under the caption  "Implementation  of the Orion
Satellite System."     

THE ORION STRATEGY

   Orion's  strategy is to  maximize  its  revenues  per  satellite  transponder
through the delivery of value-added  services to end users. To quickly establish
a  stable  base  of  revenues,   Orion  sells  transponder   capacity  to  video
broadcasters  and  telecommunications   service  providers.   However,   Orion's
long-term  strategic  focus is on value-added  private network  services,  which
include network design, VSAT installation,  support and monitoring,  in addition
to basic satellite  capacity service.  The implementation of Orion's strategy is
based on the following elements:

   o  Focus on Specialized Communications Needs of Multinational Organizations

   o  Bridge to Emerging Markets and Remote Locations

   o  End-to-End Service

   o  Global Coverage

   o  Early Market Entry

   o  Local Presence

   o  Ownership of Facilities


   FOCUS ON SPECIALIZED COMMUNICATIONS NEEDS OF MULTINATIONAL ORGANIZATIONS


   Orion  targets  the  needs  of  multinational   businesses  and  governmental
customers for customized private network communications services.  Advantages of
the Company's  satellite-based  network services include:  (i) transmission over
wide areas to multiple dispersed sites including sites in emerging markets; (ii)
interconnectivity  among all sites;  (iii) wide  bandwidth and high data speeds;
(iv)  transmission  of  data,  fax,  teleconferencing  and  voice  over the same
network; (v) high transmission reliability,  quality and security; (vi) Internet
access; and (vii) rapid  implementation,  both for the initial  installation and
for later network modifications. Due to the flexibility of the network, Orion is
able to provide companies with customized solutions to link multiple locations.


   BRIDGE TO EMERGING MARKETS AND REMOTE LOCATIONS


   Orion  targets  customers  doing  business  in  emerging  markets  and remote
locations  of  developed  markets  which  often lack the fiber optic and digital
infrastructure  required  for wide  bandwidth,  high  speed  data  applications.
Terrestrial  transmissions  in many  emerging  markets  must often pass  through
local,  poorly developed network segments before reaching the customer premises,
making it difficult to

                                       47

<PAGE>

send and  receive  high  speed  data.  In  contrast,  Orion's  satellite  system
completely  avoids such  "bottlenecks"  in local network segments by sending and
receiving  transmissions  directly to and from  customers,  avoiding the need to
interconnect  with the local  infrastructure.  A significant  portion of Orion's
private  communications  network customers transmit  high-speed data to and from
locations  in  Central  and  Eastern  Europe.  Orion 2 and  Orion 3 will  extend
coverage to the Commonwealth of Independent  States,  Latin America and the Asia
Pacific Region.


 END-TO-END SERVICE

   Orion provides its services  directly to and among customer  locations  using
satellite  transmission  and VSATs  installed  at  customer  premises.  Offering
end-to-end  services and bypassing  terrestrial  infrastructure  allows Orion to
offer higher  reliability  and higher  quality  services  than some  terrestrial
facilities by bypassing multiple  telecommunications service providers and local
networks and avoiding  related toll  charges.  It also permits  Orion to install
networks more quickly than many of its competitors,  who must deal with multiple
vendors and multiple  communications  technologies.  Orion offers its  customers
one-stop  shopping.  This includes a single point of contact,  an  all-inclusive
contract and consistent quality of service throughout the network.

 GLOBAL COVERAGE

   Orion believes that providing  global coverage is a competitive  advantage in
marketing to multinational  corporations.  Orion 1 covers 34 European countries,
much of the U.S. and  portions of Canada,  Mexico and North  Africa.  Orion uses
capacity  leased from other  carriers to  supplement  its network  coverage area
(such as to areas of Russia and Latin America).  Orion estimates that when Orion
2 (with coverage of Europe,  Russia,  the eastern United States,  Latin America,
North Africa and the Middle East) and Orion 3 (with coverage of the Asia Pacific
region) are deployed,  the satellite  footprints in the aggregate  will cover an
area inhabited by over 85% of the world's population.  This coverage will enable
Orion to offer its customers a single source for service offerings and a greater
measure of network quality control than terrestrial alternatives.

 EARLY MARKET ENTRY

   Orion develops an early market presence in targeted geographic areas prior to
satellite  launch in order to build its customer base. To accomplish this, Orion
hires sales people,  develops relationships with ground operators,  and delivers
its services using leased satellite capacity. Orion employed this strategy prior
to the  commercial  operation of the Orion 1 satellite  and is pursuing the same
approach  with  Orion 2 and  Orion 3. For  example,  the  Company  is  currently
providing service in Latin America and Russia over leased satellite capacity.

 LOCAL PRESENCE

   Orion has arrangements with 30 local ground operators covering most countries
within the Orion 1 footprint, and is entering into additional arrangements as it
offers services in new areas.  These ground  operators are critical to providing
integrated service because they obtain necessary licenses,  install and maintain
the  customers'  networks,  provide  in-country  business  experience  and often
facilitate market entry.

 OWNERSHIP OF FACILITIES


   Orion believes it is strategically important to own its satellite facilities.
Orion  believes  that  over the  long-term  ownership  of  satellite  facilities
provides a cost  advantage over  resellers and other private  service  providers
that must  lease  satellite  capacity  to provide  services  to  customers.  The
Company's  satellite ownership enables it to control the quality and reliability
of its network solutions,  maintain the flexibility to rapidly add capacity, new
locations  and new features to its  customer  networks,  and respond  quickly to
customer requests.

INDUSTRY OVERVIEW

   Fixed communications  satellites are generally located in geostationary orbit
approximately 22,300 miles above the earth and blanket large geographic areas of
the  earth  with  signal   coverage.   Satellites   are  thus  well  suited  for
transmissions that must reach many locations over vast distances  simultaneously
(i.e.,   point-to-multipoint   transmissions),   such  as  the  distribution  of
television  programming to cable operators,  television stations and directly to
homes.  Satellites  can be  accessed  from  virtually  any  location  within the
geographic  area they cover.  This  ubiquitous  coverage allows the satellite to
transmit voice and data  communications to remote locations and emerging markets
where terrestrial infrastructure is not well developed. Historically, satellites
were used primarily for international voice and data traffic,  using large earth
stations that enabled lower-power satellites to function as "cables in the sky."
The principal  drawback to  satellite-based  voice  transmission is the 1/4 of a
second delay caused by the signal  traveling to and from the  satellite.  In the
U.S.,  Western  Europe and Japan,  the use of  satellites  for voice traffic has
decreased  since the early 1980s with the growth of fiber optic cable  networks.
Geostationary  satellites now are used  primarily for  television  distribution.
However,  voice and data  traffic  remains the  dominant  use of  satellites  in
developing countries.

   Prior to the  late  1970s or early  1980s,  most  terrestrial  infrastructure
consisted of copper wire (and, to a lesser extent, microwave systems), which was
well suited for  ordinary  telephone  service.  Today most  developed  economies
employ fiber optic cables,  which provide much wider  bandwidth than copper.  In
addition,  transoceanic  cables  now link most major  industrialized  countries.
Fiber optic  cables are well suited for carrying  large  amounts of bulk traffic
between two fixed  locations,  and unlike copper wire facilities have sufficient
capacity to carry the high speed data communications that comprise an increasing
percentage of  communications  traffic.  However,  in many less developed areas,
terrestrial  facilities  still consist mainly of copper wire. Even in areas with
fiber optic  networks,  the "last mile"  connections to customer  premises often
consist of copper  wire.  As a result,  customers  with sites in areas which are
underdeveloped or which have not upgraded their "last mile" copper wire to fiber
optic  cable  often do not have  access  to the full  range of high  speed  data
communications demanded by many businesses.

   Satellites  provide a number of advantages  over  terrestrial  facilities for
many high speed communications  services.  First,  satellites provide ubiquitous
service within their  footprint and can deliver  service  directly to customers'
premises.  Satellites enable high speed communications service where there is no
suitable  terrestrial  alternative  available.   In  addition,   satellites  can
completely bypass terrestrial network congestion points, "last mile" bottlenecks
and  unreliable  networks of incumbent  service  providers  to provide  advanced
services to locations where  conventional  terrestrial  service is available but
inadequate.  Second,  the  cost to  provide  bandwidth  via  satellite  does not
increase with the distance between sending and receiving stations. Not only must
terrestrial networks add physical capacity to cover additional  distances,  they
must also continually reamplify transmission signals. Satellites are well suited
for   transmission   across  large   distances,   for  wide  bandwidth  and  for
point-to-multipoint   (broadcast)   applications.   Finally,   since  VSATs  are
relatively easy to install and/or relocate, high power satellite networks can be
rapidly installed, upgraded and reconfigured. In contrast, installation of fiber
optic cable is expensive,  time consuming and requires obtaining  rights-of-way.

   The current generation of high power Ku-band satellites,  such as Orion 1, is
particularly well suited to provide high speed business  communications services
in addition to video distribution  services.  The use of the Ku-band frequencies
(as  opposed to the  C-band  used by older  generations  of  satellites)  offers
reduced interference with ground communications.  This enables satellites to use
the higher  broadcasting  power necessary to support small,  low-cost VSAT earth
stations and makes it cost effective to transmit to or among numerous locations.

DATA NETWORKING

   During the past decade,  there has been significant growth in data networking
applications. The data networking market includes a number of types of services,
including  leased  lines for private  networks,  public data  network  services,
managed  network   services,   frame  relay  and  other  services  such  as  ATM
(asynchronous transfer mode) and WAN (wide area network) services. Ovum, Ltd. (a
U.K.-based con-

                                       49

<PAGE>



sulting  firm)  estimates  that  revenues  from  the X.25  packet-switched  data
networking  services in Western Europe alone totaled  approximately $2.7 billion
in 1996,  excluding revenues from such services as leased lines, frame relay and
ATM. Data networking applications include:

   Private network services;  intranets.  Many companies are utilizing their own
"private" networks to meet their specific communications requirements, including
voice  and  data  communications,   business  television  transmissions,   video
teleconferencing,  high speed fax and e-mail.  Corporate  networks  offer higher
performance,  greater  control and  security  than can be  provided  through the
public  network.   Corporations  are  also  taking  advantage  of  intranets  to
distribute information within their own companies using Internet technologies.

   Data inquiry,  collection and retrieval. Hotel and travel reservation systems
and  financial  enterprises  use private  communications  networks  for database
inquiries  and  retrieval of  information  stored on  computers.  Banks use such
networks to verify account  balances and connect  automatic  teller  machines to
computers.  Retail  establishments  verify credit standing and gather  inventory
information. Other businesses use private communications networks to gather data
from multiple locations and transport it to central locations for analysis.

   Internet. Business and consumers rely on the Internet for a growing number of
services,  including  research,  e-mail,  data exchange,  software and graphics,
financial  services  and  shopping,   and  even  voice   communications.   These
applications  are predicted to continue to expand and diversify in the future as
enabling technologies mature.

   Image  transmissions.   Manufacturing,   publishing,   research  and  medical
industries  use  dedicated  communications  networks for  high-resolution  image
transmissions requiring large amounts of bandwidth.

   Government  networks.  Network  telecommunications  are  employed for complex
military and nonmilitary government  applications,  including administrative and
logistical  functions,  that require high security and customer network control.

   Orion  believes  that the  demand  for  international  data  networking  will
continue to grow as a result of (i) the shift to client/server  computing,  (ii)
the  proliferation  of bandwidth  intensive  applications and the development of
protocols such as frame relay to handle these applications, and (iii) use of the
Internet and intranets as part of main-stream corporate communications.

        (i)  Shift  to  client/server  computing.  Businesses  are  increasingly
     shifting  from using large host  computers  and  centralized  data  network
     architectures  to  distributed PC and  workstation  based  platforms.  As a
     result, businesses require more private network infrastructure to establish
     and interconnect  local and wide area networks.  As businesses  expand, the
     ability to link multiple locations becomes more important.

        (ii)  Proliferation of bandwidth  intensive  applications;  frame relay.
     Companies  are relying  more  heavily on  applications  such as CAD/CAM and
     image transfer that require more  bandwidth and result in traffic  patterns
     that involve  bursts of  transmissions.  In addition,  there is  increasing
     demand  for  near-instantaneous   response  time  and  more  reliable  data
     transport.  Frame relay services support these  applications and reduce the
     cost of fully and  partially  meshed  networks.  The Company  expects  that
     demand for frame relay  services will  experience  rapid growth through the
     year 2000.

        (iii)  Expansion  in Internet  and  intranet  services.  The Internet is
     becoming a major vehicle for economic and social  activity  enabling broad,
     global access to financial and business information, research material, and
     information on leisure, arts and general interest topics.  Business uses of
     the Internet include communication within and among businesses,  electronic
     commerce,  advertising  and  merchandising.  Internet usage has also led to
     increased  demand  for  "intranet"  services  for  corporate  applications.
     Intranet servers are used for publishing  information,  processing data and
     data-based  applications and collaboration  among employees,  vendors,  and
     customers.

   The significant growth in data networking services has led to rapid growth in
demand for satellite-based networks. Multinational companies are not always able
to implement client/server architectures, install wide bandwidth applications or
employ Internet and intranet solutions in every market due to 

                                       50

<PAGE>



underdeveloped terrestrial communications  infrastructure.  Therefore, a growing
use of VSATs is to  provide  wide  bandwidth  capacity  to  industrial  sites in
emerging  markets  and remote  locations.  Recent  Comsys  and Price  Waterhouse
reports  have  identified  an  installed  base of 140,000  to 160,000  VSATs and
predict significant worldwide growth over the next few years.

ORION MARKET OPPORTUNITY

   The Company believes that demand for satellite-based  communications services
will  continue to grow  because of (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  U.S.,  (iv)  increased  size  and  scope of
television   programming    distribution,    (v)   worldwide   deregulation   of
telecommunications markets and (vi) continuing technological advancements.

        (i)  Expansion  of  business   beyond  the  limits  of  wide   bandwidth
     terrestrial   infrastructure.   Overall   growth   in   the   international
     telecommunications market reflects the increasingly international nature of
     business,  the increasing  importance of emerging and newly  industrialized
     economies and the increase in international trade. International businesses
     expanding into emerging markets often rely on the incumbent  communications
     service  providers  for voice  circuits.  However,  as large  organizations
     increasingly rely on more sophisticated, high speed communications services
     to  run  their  businesses,   many  of  these  companies  face  operational
     bottlenecks when attempting to implement more sophisticated  communications
     networks.  These  problems are faced both by companies in emerging  markets
     and  companies  in  developed  markets  that  rely on  "last  mile"  copper
     infrastructure  to  interconnect  with a fiber  optic  network.  Satellites
     provide wide bandwidth  end-to-end  service  directly  connecting  customer
     premises and bypassing the limitations of terrestrial facilities.

        (ii)  Accelerating  demand for high speed data  services.  The growth of
     graphical   user   interfaces,   the   popularity  of   bandwidth-intensive
     applications  such  as  CAD/CAM,   the  incorporation  of   high-resolution
     electronic images into business processes and video  teleconferencing  have
     necessitated  major upgrades of corporate data networks to accommodate  the
     high data transfer  requirements of these applications.  Most of these high
     speed data  services  require  fiber  optic  cable or other high  bandwidth
     connections to the customer premises.  Even in developed markets, the "last
     mile"  connection to the customer  premises  often consists of copper wire,
     which cannot  support many high speed data  services.  Satellites  are well
     positioned to take  advantage of this trend  because they provide  reliable
     high bandwidth service  everywhere in their coverage areas,  reaching sites
     in underdeveloped areas, and bypass "last mile" copper wire facilities that
     are unable to support high speed communications.

        (iii) Demand for Internet and intranet services.  The growth in Internet
     and   intranet   services   has   further   strained    corporate   network
     infrastructures.  The  utility  of  Internet  services  to  users  is often
     constrained by the lack of sufficient bandwidth to support  high-resolution
     graphical  applications and images.  Even where  infrastructure  quality is
     high,  the  rapid  growth  of the  Internet  continues  to  create  network
     congestion.  Users are sometimes unable to use current-generation  software
     or gain high speed  access to the Internet due to the poor quality of their
     local  terrestrial  infrastructure.  Satellites  have  many  advantages  in
     delivering  Internet  services.  Satellite-based  networks provide services
     directly  to  customer  premises,  bypassing  terrestrial  bottlenecks  and
     congested  Internet  routing  facilities.  In  addition,   satellite  based
     networks  can be  designed to support  asymmetric  and  multicast  Internet
     traffic much more efficiently than terrestrial networks.

        (iv)  Increased size and scope of television  programming  distribution.
     The global television market is experiencing  significant  growth,  both in
     terms of the number of broadcasters  creating programming and the number of
     channels  available to viewers.  Within the U.S.,  the number of television
     broadcast and cable television  program networks grew from three in 1970 to
     over 100 in 1993 and to approximately  200 in 1996. U.S. and  international
     broadcasters  are seeking to expand into each others'  markets,  increasing
     the need for satellite  transmission  capacity.  Non-U.S.  broadcasters are
     using international  satellites to distribute domestic  programming to U.S.
     and other overseas audiences of similar cultural heritage. Furthermore, the
     Company believes that as the number

                                       51

<PAGE>



of  broadcasters  and channels  increases,  individual  competitors  will have a
greater need for competitive differentiation which will increase the use of live
transmissions  and  expand  television  coverage.  Multichannel  programming  is
expanding  rapidly in Eastern  Europe,  Latin  America  and Asia.  The growth in
multichannel programming has increased the demand for international  programming
such as news and sports.  Orion is well  positioned  to take  advantage  of this
growth due to its high-power Ku-band satellite and transatlantic footprint.

   (v) Worldwide  deregulation of  telecommunications  markets.  During the past
decade many countries have liberalized their telecommunications markets in order
to permit new competitors to provide facilities and services. These changes have
been particularly  apparent in Europe,  where Orion currently has the ability to
deliver  network  service to and among points in 27 countries.  Deregulation  is
also creating new competitors to national  telecommunications  companies,  which
represent potential additional customers for the Company's services.

   (vi)   Continuing   technological   advancements.    The   following   recent
technological advances are expected to increase capacity,  efficiency and demand
for satellite services:

        1. High Power  Satellites.  The ability of service  providers to deliver
     high quality  services  directly to customer  premises has greatly improved
     with  the  development  of  high  power  satellites.   Older,  lower  power
     satellites   require   large,   expensive   earth   stations   to   receive
     transmissions.  Typically  these earth stations were located  outside urban
     areas and required  interconnection  with public  telephone  systems.  High
     power  satellites,  such as Orion 1,  enable the use of small,  inexpensive
     VSAT earth  stations that may be installed at customer  locations,  thereby
     reducing customer costs and bypassing all terrestrial facilities. 

        2. Meshed Network Services.  Traditional VSAT networks employ a hub/star
     architecture  anchored by an expensive  hub earth station that controls the
     network and  communicates  with each of the VSATs.  Recent advances in VSAT
     technology  have  led to  the  creation  of  fully  meshed  satellite-based
     networks.  These  networks  offer less  transmission  delay  than  hub/star
     networks by enabling any network node to communicate with any other network
     node directly  through the satellite  without having to transmit  through a
     central network control point.

        3. Frame Relay.  The Company  believes  that despite  rapid  advances in
     network  services and  application  software,  many companies  hesitated to
     implement  meshed data  networks due to high  overhead  costs  generated by
     descriptive and routing commands  required to travel with the data traffic.
     Frame relay technology reduces the number and complexity of commands needed
     to send data, and enables companies to implement more cost-effective meshed
     networks.  To meet customers'  demands for fully meshed frame relay network
     services, the Company has developed its VISN service.


        4. Compressed  Digital Video.  CDV technology is designed to compress up
     to ten high-quality  video channels into the same bandwidth that previously
     carried one or two analog  channels.  This  technology  is creating a rapid
     expansion  in  the  number  of  available   video  channels  with  improved
     transmission  quality.  CDV  lowers  the  per-channel  cost  of  delivering
     programming via satellite and cable  television  systems,  thereby enabling
     more  programming  options to be provided to smaller  markets.  The Company
     believes  that CDV will  enable  continued  growth  in the  number of video
     channels and also  accelerate  broadcasters'  efforts to  distribute  their
     programming internationally. The Company also believes that CDV will result
     in higher total  revenues per  transponder  as more customers can be served
     per  transponder.  However,  CDV may also in effect  increase the supply of
     satellite  transponders,  causing  prices to decline.  See "Risk Factors --
     Potential  Adverse Effects of Competition."  Although CDV is just beginning
     to be adopted in the industry, as of September 30, 1996,  approximately 63%
     of Orion's video customers used CDV technology.

ORION SERVICES

   Orion provides  satellite-based digital communications services comprised of:
(i)  private  network  services  for  multinational  business  and  governmental
customers, (ii) Internet backbone and access ser-

                                       52

<PAGE>

vices  and (iii)  satellite  transmission  capacity  services,  including  video
distribution  services for  broadcasters,  news  organizations and international
carriers.  As indicated by the charts below, 61% of revenues for the nine months
ended  September  30,  1996 were  derived  from the sale of  satellite  capacity
(primarily for video distribution  services).  However,  62% of bookings for the
nine months  ended  September  30, 1996 were from  private  network and Internet
services. These figures are consistent with the Company's strategy of building a
stable base of revenues through sales of transmission capacity and then focusing
on the delivery of value-added private network services to end-users.

                                   [GRAPHIC]

*    Bookings  represent new customer  contracts executed during the period. See
     "Risk Factors -- Uncertainties Relating to Backlog."

 PRIVATE COMMUNICATIONS NETWORK SERVICES

   International  Leased  Line  Services.   Orion's  international  leased  line
services include Digital Link and Digital  Channelized Link. Digital Link can be
designed as a  "point-to-point"  private  network  service  directly  connecting
customer locations or as a  "point-to-multipoint"  service for customers seeking
to transmit  communications  from a central  location to numerous  remote sites.
Orion also offers  Digital  Channelized  Link, a multiplexed  version of Digital
Link that integrates  digitally  compressed  voice,  fax and data traffic into a
single  channel.  Digital Link and Digital  Channelized  Link services have been
offered by Orion since 1993. International leased line services have constituted
a majority of Orion's  bookings of private  communications  network  services to
date.

   One  customer,  a  major  multinational  consumer  goods  company,   required
voice/fax and data  connectivity from nine offices in Central and Eastern Europe
to the company's U.S. headquarters, utilizing data speeds of up to 128 Kbps. The
sites are  manufacturing  centers for the customer's soap and toiletry  products
and the customer uses Orion's service for managing  inventory and "just-in-time"
order entry. The customer was seeking a "one-stop  shopping"  solution delivered
by a single network service provider.  The customer investigated two alternative
networking solutions and selected satellite  connectivity provided by Orion over
terrestrial facilities provided by the local PTTs due to superior quality.

   International  Data Networking  Services.  Orion's  fully-meshed  frame relay
based  international data networking  service,  "Virtual Integrated Sky Network"
("VISN"),  allows  customers  to  transmit  and  receive  voice,  fax  and  data
communications,   including   intranet   services,   among  multiple   locations
simultaneously.  VISN was  developed  by Orion and is produced by Nortel Dasa (a
joint venture among Northern  Telecom,  Dornier GmbH, and Daimler Benz Aerospace
AG). The first phase of this service became available to customers commencing in
the third  quarter  of 1995,  and  subsequent  phases of the  service  have been
introduced during 1996 and are expected to be introduced during 1997,  including
the  addition of video  teleconferencing.  VISN offers  customers  bandwidth  on
demand for data, voice and fax and, following the introduction of in-process and
future releases, customers will have the option to be charged on a "pay per use"
basis  (e.g.,  minutes of use for voice and volume for data).  VISN employs TDMA
technology,  which further increase the effective  bandwidth  available for data
transmission.  The VISN 

                                       53

<PAGE>


product was awarded "Best New Transport  Technology  Product" at the 1995 ComNet
New Product Achievement Awards Competition. Most customers have between four and
ten sites,  and  generally  have  minimum  data  rates  with the  ability to use
substantially greater bandwidth for bursts of traffic.

   A VISN customer,  Creditanstalt  Bankverein,  Austria's  second largest bank,
needed a voice and data network among all of its branches in Central and Eastern
Europe. Data applications  varied from electronic mail to transfer  transactions
to its data  center in Vienna,  along with voice  requirements  for  interoffice
telephone   calls  and  facsimile   transmission.   Creditanstalt   investigated
terrestrial  leased  line and  dial-up  services  to satisfy  its  requirements.
Orion's VISN service  offered full meshed,  frame relay  network  service  which
supports both  voice/fax  and data  transmission  simultaneously.  Creditanstalt
replaced its terrestrial network with a nine site VISN network using data speeds
of up to 256 Kbps.

 INTERNET BACKBONE AND ACCESS SERVICES

   The  Company  believes  that the rapid  growth of the  Internet  has  created
substantial  opportunities  for Orion.  First,  the United States has become the
residence of the majority of the world's Internet content. Companies are looking
for reliable, wide bandwidth connections which bypass congested Internet network
segments. Orion's transatlantic capacity is well suited for companies in Europe,
including Internet Service Providers ("ISPs"),  seeking high-speed access to the
U.S.  Internet.  Second,  the Internet has begun to evolve from a user  centered
"pull" environment (users requesting information) to a content provider centered
"push" environment  (information delivered to users without concurrent request).
Broadly distributed entertainment,  information and advertising via the Internet
are well suited for broadcast,  point-to-multipoint  communications  facilities,
such as satellite.  By using  satellite  broadcasts to transmit the most popular
Internet content to regional locations,  ISPs can reduce their costs and relieve
network  congestion.   Finally,   Internet  data  communications  are  typically
asymmetric.  A typical, large Internet data transmission is predicated by a user
request  that  comprises  only a few  bytes  of  traffic.  This  interaction  is
inefficient when carried over terrestrial full-duplex networks,  which carry the
same  capacity in both  directions.  Orion's  satellite  based  solutions can be
designed  with  different  amounts of capacity in each  direction,  providing an
inexpensive  circuit for user  requests and  high-speed,  reliable and available
capacity for the data that flows back to the user. 

   Although Orion's Internet services were introduced only in the second quarter
of 1996, sales of such services  constituted 16% of new service bookings for the
nine months  ended  September  30, 1996.  Orion  offers  three  Internet-related
services, described below.


   ISP Backbone  Service.  Orion's  DirectNet I service is designed for European
ISPs.  The  service  combines a  dedicated,  high speed  point-to-point  circuit
between the ISP's points of presence in Europe and the North  American  Internet
through a dedicated,  fully  redundant  backbone  connection.  Orion also offers
additional  features with its  DirectNet I service,  including  24-hour  network
monitoring,  control and support and a 99.5% network availability  guarantee and
associated  downtime  credits.  Orion is pursuing  requirements or joint venture
arrangements  with ISPs in which  all of their  transatlantic  traffic  would be
carried over Orion 1 as it develops.  For example, Orion has an arrangement with
PSINet  Inc.  in which Orion has agreed to serve as the  supplier  for  PSINet's
backbone,  connecting  PSINet's various points of presence in Europe to the U.S.
Internet backbone. Orion's ISP customers include, for example, companies such as
Global  Ukraine,   an  ISP  based  in  Kiev.   Global  Ukraine  sought  Internet
connectivity  to the United States  backbone with advanced  technical  features.
Orion now  provides  Global  Ukraine with a 256 Kbps circuit from the Ukraine to
the United  States with a  connection  into the U.S.  Internet at three  network
access  points,  providing  route  diversity  and ensuring fast response time by
avoiding points of potential network congestion. Orion does not expect DirectNet
I to generate more than 10% of its revenues.

   Corporate  Internet  Access.  Orion's  DirectNet  II  service  is  offered to
international corporations requiring high volume data transmission in connection
with  World  Wide  Web  browsing  and  downloading.   DirectNet  II  provides  a
point-to-point circuit between the North American Internet and the corporation's
premises.  Orion offers large corporations  Internet access service by reselling
the Internet access services of several large ISPs, such as DIGEX and UUNet.

                                       54

<PAGE>

   Multicast  Satellite-Based  Internet Services.  Orion recently introduced its
WorldCast  service which allows ISPs or corporate users to significantly  reduce
Internet  bandwidth  and  ground  facility  costs.  The  service  is based on an
asymmetric architecture which couples wide bandwidth satellite broadcasting with
narrow bandwidth terrestrial links to the Internet.  Furthermore,  WorldCast can
provide a single channel that is shared among multiple ISPs,  which can remove a
significant  amount of traffic from ISP  terrestrial  networks.  The Company has
recently  taken  orders  from  customers,  but is not  currently  providing  any
customers with this service.

 VIDEO DISTRIBUTION AND OTHER SATELLITE TRANSMISSION SERVICES


   Orion provides  transmission  capacity to cable and  television  programmers,
news and information networks,  telecommunications  companies and other carriers
for a variety of applications.  Approximately two-thirds of Orion's transmission
capacity  services  consist of video services.  The Company offers  transmission
capacity  services under long term  contracts,  with  approximately  35% of such
services being under contracts of three years or less, 14% being under contracts
of  approximately  four to six years in  duration  and  approximately  51% being
delivered  under  longer  term  contracts  (such  percentages  being  based upon
contract values).  The remainder consists principally of occasional use services
for periods of up to a few hundred hours.

   Video   Services   --   Contribution.    Orion's   video   services   include
"contribution,"  the  long-distance  transport of video signals  (usually one or
more  television  channels) to one location.  Viacom has leased capacity for one
channel on Orion 1 for the purpose of occasional or full time  transmission  for
video  programming from its U.S.  facilities to a broadcast  facility in London.
From  there it can be  inserted  into  programming  and  rebroadcast  in Europe.
Orion's  contribution  services also include  transport of news  programming for
RTL, a major commercial broadcast network in Germany. RTL needed to interconnect
its various news bureaus in Germany and the U.S. to transmit news stories to its
headquarters  in Cologne.  Orion provided 24 MHz of  transatlantic  transmission
capacity  service  allowing  transmission  of RTL's  programming  in  compressed
digital video format.

   Video Services -- Distribution.  Cable and television programmers use Orion's
satellite  transmission  services for distribution of television  programming to
local  broadcast  stations,   cable  head-ends,   MMDS  (multichannel  microwave
distribution) systems and SMATV (satellite master antenna television). Orion has
a joint  marketing  agreement  with NTL, which operates one of the largest video
gateways in Europe,  located in downtown London. Orion and NTL offer programmers
uplink,  compression and  distribution to cable head-ends  throughout the United
Kingdom and to locations in Europe.  Orion's ability to offer video distribution
services is aided by the  transponder  switching  capabilities of Orion 1, which
are (and those of Orion 2 and Orion 3 are  expected  to be)  designed  to permit
programs to be distributed  simultaneously  throughout the satellite's  coverage
area.

   Orion's video distribution customers include Black Entertainment  Television,
Inc.  ("BET"),   which  was  seeking  a  video  distribution   service  for  the
distribution  of its  BET On  Jazz  International  Network,  an  internationally
distributed  programming  network  dedicated  to  international  Jazz and  Blues
artists.  BET required  receipt of its signal at its headquarters in Washington,
D.C., conversion to a European TV standard, digital compression and uplinking of
the compressed  digital video signal for  distribution to cable head ends in the
United Kingdom and other sites in Europe.

   News and Special Events.  Orion 1 is used for  transmission of special events
or remote  feeds to  international  news bureaus  from  television  stations and
on-location  mobile  transmitters.  Because Orion's Ku-band  technology and VSAT
ground segment infrastructure offers high reception sensitivity,  the Company is
especially  effective in transmitting  television  signals sent from low-powered
portable   transmitters   typically  used  by  news  organizations  and  program
distributors.  In  contrast  to video  contribution  services,  news and special
events are  characterized  by  occasional  use rather  than  long-term  capacity
contracts.  CNN selected  Orion's service for its coverage of Bosnia,  and Orion
provided service to the European Broadcasting Union for coverage of the Olympics
in Atlanta.

   International  Carriers.  Orion satellite  transmission  services are used by
international  carriers to provide backup for  terrestrial  lines and to provide
communications   services   to   areas   with   inadequate    telecommunications
capabilities.  These  carriers  resell  Orion's  capacity  as part of their  own
services.



                                       55

<PAGE>


   Capacity  Sales.  Orion  sells bulk  capacity  to  resellers  who use Orion's
transmission capacity as one component of a customer's end-to-end communications
solution.  For example, Orion currently sells capacity to a number of firms that
resell Orion's capacity to governmental organizations.


   Orion offers a range of value-added  services in  conjunction  with its video
distribution  and other  satellite  transmission  services.  Such  services  may
include  the  provision  of video  uplinking  and  receiving  stations,  digital
compression  equipment  and  software,   transmission   monitoring  and  gateway
interconnection services.

FEATURES AND BENEFITS

   Orion's  satellite-based  services  offer  customers  a number  of  important
features, which provide significant benefits versus competing alternatives.

   Bypass  terrestrial  network and multiple  international  connection  points.
Orion's ability to bypass terrestrial  facilities  improves service  reliability
and quality by reducing  potential  points of failure and  avoiding  "last mile"
limitations. In addition,  terrestrial bypass allows Orion to avoid the multiple
in-country toll charges of terrestrial facilities and thereby reduces cost.

   Direct  end-to-end  service to customer  sites.  Orion provides  service from
rooftop to rooftop using VSAT earth stations located on customer premises.  This
"end-to-end service" is reliable, rapidly installed,  easily upgraded and avoids
the "last mile" limitations of some terrestrial alternatives.

   Ubiquitous  coverage.  Orion  delivers  wide  bandwidth  service to  emerging
markets  and  remote   locations  where  there  are  no  effective   terrestrial
alternatives.

   One-stop  shopping.  Orion  provides  its  customers  with a single  point of
contact for customer care, including service, billing and support.

   Two-way  communications  for all sites.  Orion's meshed network solutions and
frame  relay  services  promote  network  efficiency  and allow  real-time  data
transfer among dispersed network points.

   Well-suited for asymmetric  communications traffic. Orion's network solutions
can be  designed  to  carry  asymmetric  traffic  efficiently,  which  increases
performance and lowers cost to customers for services such as Internet services.

   Point to multipoint capability.  Orion's ability to broadcast video, data and
voice to multiple locations simultaneously enables efficient network design.

   High power Ku-band transmissions,  high reception  sensitivity.  Orion's high
power  transmissions  allow  customers to lower costs by utilizing  small,  less
expensive earth station  equipment.  Orion 1's reception  sensitivity allows for
effective reception from portable earth stations, an advantage in satellite news
gathering.

   Cost-competitive.  Orion  prices its  services  to be  competitive  with both
satellite-based and terrestrial alternatives.

   Orion has entered into a contract with DACOM Corp.,  a Korean  communications
company which provides international and long distance telephone and leased line
services, international and domestic data communications and value added network
services. Under the contract,  DACOM will, subject to certain conditions,  lease
eight  dedicated  transponders  on  Orion  3 for  13  years  for  direct-to-home
television  service and other  satellite  services,  for $89 million  payable in
installments  from  December  1996  through  seven  months  following  the lease
commencement  date of the  transponders.  DACOM has the right to  terminate  the
contract  before March 1997 (and Orion would retain the $10 million  paid) if it
fails to obtain certain approvals. Payments are subject to refund if Orion 3 has
not been successfully  



                                       57

launched and commenced  commercial  operation by June 30, 1999. Although Orion 3
is  scheduled  to be  launched  in the fourth  quarter of 1998,  there can be no
assurance  that  Orion  will be able to meet the  delivery  requirement  of this
contract.

   Backlog.  At September  30,  1996,  Orion had  approximately  $123 million of
contracts  in  backlog   (after  giving  effect  to  the  Exchange  and  related
transactions, which will result in changes to arrangements with Limited Partners
that reduce backlog by approximately $11 million),  as compared to approximately
$95 million at September 30, 1995. The backlog contracts generally have terms of
between three and four years.  Orion presently  anticipates  that at least $86.4
million of its backlog will be realized  after 1997.  Orion has begun to receive
contract  renewals  under  expiring   contracts  (under  some  of  the  earliest
contracts,  which  were  entered  into in 1993).  The size of  contracts  varies
significantly,  depending on the amount of capacity required to provide service,
the  geographic  location  of the  network and other  services  provided.  As of
September 30, 1996, Orion had a VSAT installation backlog of 68 units.

   Although many of the Company's  customers,  especially  customers under large
and long-term  contracts,  are large  corporations  with  substantial  financial
resources,  other  contracts  are with  companies  that may be  subject to other
business or  financial  risks.  If  customers  are unable or  unwilling  to make
required  payments,  the Company  may be required to reduce its backlog  figures
(which would result in a reduction in future revenues of the Company),  and such
reductions  could be substantial.  The Company has recently  instituted  tighter
credit policies,  and has taken steps to remove from backlog  arrangements  with
customers who have not taken service or have not made all required payments.  In
the second quarter of 1996, the Company determined that one large customer under
a long-term contract (accounting for backlog of approximately $19.9 million) was
not likely to raise the necessary  financing to commence its service in the near
future,  and accordingly  the Company no longer  considers such contract part of
its backlog.  Also in the second quarter of 1996,  the Company  removed from its
backlog contracts with a customer  (accounting for backlog of approximately $4.5
million)  which had ceased  paying  for the  Company's  services.  In the fourth
quarter of 1996, the Company  removed $10.4 million from its backlog  related to
contracts under which customers  failed to use the contracted  service or failed
to make timely payment.  The Company's contracts commence and terminate on fixed
dates.  If the Company is delayed in commencing  service or does not provide the
required service under any particular  contract,  as it has occasionally done in
the past, it may not be able to recognize all the revenue it initially  includes
in backlog under that contract.  In addition,  the current backlog contains some
contracts  for the  useful  life of  Orion 1; if the  useful  life of Orion 1 is
shorter  than  expected,  some  portion of backlog  may not be  realized  unless
services  satisfactory  to the customer can be provided over another  satellite.
See "Risk Factors -- Uncertainties Relating to Backlog." 

SALES AND MARKETING

   Orion uses both direct and indirect sales channels. Orion markets its private
communications  network  services and Internet  services  through  direct sales,
local  representatives  and  distributors  in Europe and the United States,  and
wholesale   arrangements  with  major  carriers,   Internet  service  providers,
resellers  and systems  integrators.  Orion markets its video  distribution  and
other satellite transmission services primarily through direct sales. Orion also
has established  arrangements  with local companies in most countries within the
Orion 1 footprint to assist Orion with selling  efforts and to provide  customer
support and network maintenance functions in those countries (as discussed below
under the caption "Network Operations; Local Ground Operators").

   Orion  generally will enter into a single  contract with  customers  covering
service to a number of  countries.  Orion offers the business  customer a single
point-of-contact,  a single contract and one price for its entire network, which
Orion believes  constitutes true "one-stop  shopping." Orion prices its services
centrally,  using a single,  easily  administered set of pricing  procedures for
customer networks.

   Marketing  will be critical to Orion's  success.  However,  Orion has limited
experience in marketing,  having  commenced full commercial  operations in 1995.
Orion's marketing program until recently  consisted of direct sales using a U.S.
based sales force and indirect sales channels,  including  Limited Partner sales
representatives,  for sales in Europe. The majority of Orion's contract bookings
to date have been


                                       58

<PAGE>

generated by its direct sales force.  Certain of Orion's indirect sales channels
in Europe have not met expectations. Orion has been significantly increasing its
direct  sales  capabilities  in Europe,  particularly  with  respect to sales of
private  communications  network  services.  Although  Orion  believes  that the
increase in its European sales  capabilities  will increase its bookings,  there
can be no assurance  regarding the timing or amount of such  increase.  Sales of
Orion's  services  generally  involve a long-term  complex  sales  process,  and
Orion's  bookings  have  fluctuated  significantly.  See "Risk  Factors -- Risks
Relating to Potential Lack of Market Acceptance and Demand;  Ground Operations."

   The  Company  may from time to time  enter  into  joint  ventures  or acquire
businesses  which  provide it with  additional  customers  or which  enhance its
marketing  capabilities.  Although the Company is presently considering one such
possible acquisition, it does not have binding arrangements at the present time.
The Company  believes that such  acquisition,  if consummated,  would not have a
material effect on the Company. See "Risk Factors -- Risks Concerning Ability to
Manage Growth."

 DIRECT SALES

   Orion has  assembled a direct  sales force of 31 (as of December  15, 1996 as
increased from 26 at June 30, 1996) full-time employees in the United States and
Europe to offer its private  communications  network and satellite  transmission
services. Approximately 68% of the sales force is based in the United States (in
Maryland) and approximately 32% is based in Europe. Orion expects to continue to
expand its sales  force  significantly  throughout  1997,  both in the U.S.  and
Europe.

 INDIRECT SALES CHANNELS

   Representatives/Distributors.  Orion  has  entered  into  agreements  for the
marketing of its private  communications network services in the United Kingdom,
France, Germany,  Austria, Italy and other European countries.  These agreements
call  for  sales,   marketing  and  customer   support   services  in  specified
geographical areas, generally on a non-exclusive basis. Generally,  the duration
of these agreements is three years.  Third party sales  representatives  receive
commissions and fees for sales and customer support services,  each of which are
payable  over the life of the customer  contracts to which the  representative's
services  relate  and  which  are  based  upon  the  revenues   derived.   Sales
representatives are supervised by Orion sales managers,  who establish marketing
strategies with the  representatives,  establish  pricing,  attend certain sales
calls,  develop marketing  materials and sales training tools,  coordinate joint
efforts in promotional  events and provide  information  about Orion's services.
Orion also  provides  engineering  support to its sales  representatives.  Orion
provides  some  of  these   functions  to  support  the  sales  efforts  of  its
distributors.  Distributors  purchase  Orion's  services at wholesale prices and
resell those services to customers at prices determined by the distributors. Two
Limited Partners who serve as sales  representatives  (and ground operators) are
entitled to receive  additional  commissions  under a "profit  sharing"  formula
based on their  overall  contribution  to sales,  but no amounts  have been paid
under such formula to date.  Orion expects that unless  Limited  Partners  sales
representatives  increase their sales  significantly,  payments under the profit
sharing arrangement will not be material.

   Major  Carriers and Other  Wholesalers.  Orion has entered  into  distributor
resale arrangements with major carriers, teleport operators, resellers and other
companies in the United States and internationally. These distributors typically
purchase  communications  network  services  from Orion at a wholesale  rate for
resale to their  customers.  This  represents an important sales channel for the
Company, and the Company is focusing on strengthening these relationships. Major
carriers  employ  substantial  sales  forces  and  have the  advantage  of being
existing  providers to many of Orion's target  customers,  which makes marketing
easier and increases awareness of customer needs.

NETWORK OPERATIONS; LOCAL GROUND OPERATORS


   Orion  has  a  centralized  network  operations  function  at  its  corporate
headquarters  in  Rockville,  Maryland,  supported  by  arrangements  with local
companies in most  countries  within the Orion 1 footprint who assist Orion with
selling efforts and perform customer support and network maintenance  functions.
Orion's relationships with ground operators are critical to providing integrated
service be-


                                       59

<PAGE>

cause  ground  operators  obtain  necessary  licenses,  install and maintain the
customers' networks, provide in-country business experience and often facilitate
market entry.

   Network Operations.  Once the Company enters into a contract with a customer,
it  finalizes  the  design of the  customer's  network,  acquires  the  required
equipment and arranges for the  installation  and  commissioning of the network.
Upon  commencement  of  service,  Orion also  monitors  the  performance  of the
networks  through  its U.S.  based  network  management  center,  located at its
corporate  headquarters in Rockville,  Maryland,  and from facilities in Europe.
The network management center allows Orion to perform  diagnostic  procedures on
customer  networks  and to  reconfigure  networks to alter data  speeds,  change
frequencies and provide additional bandwidth. 

   Ground Operators.  Through arrangements with 30 local ground operators, Orion
currently has the ability to deliver network services (through Orion 1 or leased
capacity on other satellites) to or among points in 27 European  countries,  the
United  States and Mexico  (which  comprise  substantially  all of the countries
within the coverage area of Orion 1), as well as arrangements to deliver network
services  in  certain  other  Latin  American  countries.  The  ground  operator
agreements call for  installation  and maintenance of VSATs and other equipment,
customer support and other functions in designated geographical areas, generally
on a non-exclusive  basis.  Generally,  such ground  operations  agreements last
three years.  Orion coordinates  ground operations  services  (including service
calls) by its local agents through centralized  customer service centers located
at Orion's corporate headquarters and at its facilities in Amsterdam. Orion also
provides  its  ground  operators  with  installation  and  maintenance  training
materials and support.  Ground  operators  receive fixed fees for  installation,
maintenance  and other  services,  which vary depending on the level of services
and the geographic area.  Certain ground operators receive payments for customer
support over the life of the related customer contract,  based upon the revenues
derived. Two Limited Partner ground operators are entitled to receive additional
fees under a profit  sharing  formula,  but no amounts have been paid under such
formula  to  date  and  Orion  expects  that,   unless  such  Limited   Partners
significantly  increase the number of VSATs they maintain on behalf of Orion for
Orion's  customers,  profit  sharing  payments  will  not be  material.  Orion's
operations will continue to depend  significantly on Orion being able to provide
ground  operations  for  private  network  services  using  representatives  and
distributors  throughout the footprint of Orion's satellites.  In the event that
its network of ground  operators is not  maintained  and  expanded,  or fails to
perform as expected,  Orion's ability to offer private network  services will be
impaired.  See "Risk  Factors  -- Risks  Relating  to  Potential  Lack of Market
Acceptance and Demand; Ground Operations."

   Set forth below is a map showing the locations of Orion's  existing  European
ground operators and potential new ground operators.

[Document  contains a map of Europe  indicating where Orion has ground operators
and where Orion is negotiating the hiring of additional ground operators]

MIGRATION PLAN FOR NEW MARKETS

   Prior  to the  launch  of  Orion  1,  the  Company  began  providing  private
communications network services to customers over satellite capacity leased from
others.  This early market entry strategy is being extended to Latin America and
Asia with the execution of the Orion 2 Satellite  Contract and  commencement  of
construction  of  Orion 3 in  December  1996.  By  developing  an  early  market
presence, Orion builds its customer base, establishes  relationships with ground
operators  and becomes  familiar with the  regulations  and practices in its new
markets  prior to launch of its  satellites.  Upon the  launch of Orion 1, Orion
migrated its customer base to its own satellite, and Orion expects to pursue the
same approach for Orion 2 and Orion 3.

   In Latin America,  the Company has a relationship  with a ground  operator in
Mexico and is currently  providing service to customers in Mexico,  Colombia and
Paraguay over leased  capacity.  The Company intends to migrate such services to
Orion 2 after it commences operations,  as Orion did with its Orion 1 satellite.
The Company has three  U.S-based  direct sales  personnel  focused on selling in
Latin  America,  and is  pursuing  relationships  with  other  potential  ground
operators and joint venture partners.

   In  Asia,  the  Company  has  assigned  two full  time  personnel  to  pursue
arrangements with potential ground operators and joint venture partners, and has
commenced  discussions with such entities in a number of Asian countries.  Orion
has  begun  the  process  of  identifying  potential  sales  representatives  in
countries within the Orion 3 footprint.  The Company has also begun  discussions
with existing customers who have



                                       61

<PAGE>



operations  within the Orion 3  footprint  and have  expressed  an  interest  in
procuring  Orion's  services  in Asia.  Orion  has  started  to  identify  other
potential  multinational and Asia-based customers,  and plans to open a regional
office in Asia in the second half of 1997. The Company expects its marketing for
Orion 3 will be assisted by the $89 million  pre-construction  lease by DACOM, a
Korean   communications   company,  of  eight  of  Orion  3's  transponders  for
direct-to-home  service and other satellite services.  See "-- Implementation of
the Orion Satellite System -- Orion 3 -- Pre-Construction Customer."

IMPLEMENTATION OF THE ORION SATELLITE SYSTEM

   Orion currently provides its services with Orion 1 and with facilities leased
from  other  providers   covering  areas  outside  the  satellite's   footprint.
Ultimately  the Company  will  provide  these  services  with three  satellites,
together with  facilities  leased  outside of its  footprints.  Orion 1 provides
coverage of the Northern  Atlantic  Ocean region.  Orion 2 is being  designed to
cover the Atlantic  Ocean region but with coverage of points  further East (into
the  Commonwealth  of  Independent  States) and South  (into  Latin  America and
Africa), and Orion 3 is being designed to cover the Asia Pacific region.

   The design,  construction,  launch and in-orbit  delivery of a satellite is a
long and capital-intensive  process.  Satellites comparable to Orion's typically
cost in excess of $200 million  (exclusive of  development,  financing and other
costs)  and take two to three  years to  construct,  launch  and place in orbit.
Prior to  launch,  the owner  generally  must  obtain a number of  licenses  and
approvals,  including approval of the host country's national telecommunications
authorities to construct and launch the satellite, coordination and registration
of an orbital  slot (of which  there are a limited  number)  through  the ITU to
avoid  interference  with other  communications  systems and a  consultation  on
interference  with INTELSAT  (and EUTELSAT in the case of European  satellites).
Obtaining the necessary consents can involve  significant time and expense,  and
in the case of the  United  States,  requires  a showing  that the owner has the
financial  ability to fund the  construction  and launch of the satellite and to
operate  for one year.  The Company has  commenced  construction  of Orion 3 and
plans to  commence  construction  of Orion 2 prior to receipt of all  regulatory
approvals.  Failure  to  obtain  such  approvals  prior to launch  would  have a
material adverse effect on the Company.  See "Risk Factors -- Approvals  Needed;
Regulation of Industry" and "Regulation" below.

   Orion 1 is  expected to have an in-orbit  useful life of  approximately  10.7
years, estimated to end in October 2005, and Orion 2 and Orion 3 are expected to
have in-orbit  useful lives of 13 years and 15 years,  respectively  (based upon
present  design).  While there can be no assurances that adequate  financing and
regulatory  approvals  will be  obtained,  Orion  plans  to  launch  replacement
satellites as its satellites reach the end of their useful lives.

ORION 1

   Orion 1 was launched in November 1994 and commenced commercial  operations in
January 1995.

   Satellite Design and Footprint.  Orion 1, which is in geosynchronous orbit at
37.5' West  longitude,  is a high power Ku-band  telecommunications  satellite
that contains 28 transponders of 54 MHz bandwidth and six transponders of 36 MHz
bandwidth  (although  one of these  transponders  has not operated in accordance
with  specifications,  as described  below).  The  footprint of Orion 1 is shown
below  (although  certain  transponders  of Orion 1 can be reconfigured to match
changing business and telecommunications requirements).

                                   [GRAPHIC]


   Satellite  Construction  and  Performance.  Orion 1 was  constructed by Matra
Marconi Space's subsidiary MMS Space Systems Limited, one of the major satellite
contractors in Europe.  Orion 1 was designed both for the delivery of high-speed
data and for  high-powered  digital video  transmission  to corporate  users. In
particular, Orion 1 was designed with high reception sensitivity,  which enables
two-way  transmission  from and to small earth stations,  reducing the equipment
and  transmission  cost  to  customers.  Orion  1 has  transatlantic  networking
capability, which allows users to uplink data in the U.S. or Europe and downlink
that transmission simultaneously to the U.S.
and Europe.


   This configuration  simplifies customers' transatlantic networking solutions.
Orion  believes  that  Orion 1's  Ku-band  technology  and VSAT  ground  segment
infrastructure  is among the least  expensive,  most flexible  technologies  for
interactive  satellite  transmissions  in the North Atlantic  market.  Like most
recent satellites, Orion 1 offers digitally compressed transmission, in addition
to analog transmission, which allows the satellite to increase by up to ten fold
its usable bandwidth per transponder, leading to greater revenue per transponder
and greater network availability to customers in need of bandwidth on demand.

   When Orion 1 was delivered into orbit,  one of the 36 MHz  transponders  with
coverage  of the United  States  did not  perform in  accordance  with  contract
specifications.  Orion settled the matter with the  manufacturer  for a one time
refund of $2.75  million  (which  amount was applied as a  mandatory  prepayment
under the existing Orion 1 Credit Facility).  In addition, the manufacturer will
pay Orion approximately $7,000 per month for the life of the satellite under the
warranty to the extent the  transponder is not used to generate  revenue.  Orion
believes  that the failure of such  transponder  to perform in  accordance  with
specifications  will not have a significant  impact on Orion's  ability to offer
its services.

                                       63

<PAGE>

   In November 1995, one of Orion 1's components supporting nine transponders of
dedicated  capacity  serving  the  European  portion  of the  Orion 1  footprint
experienced  an anomaly  that  resulted  in a  temporary  service  interruption,
lasting  approximately  two hours.  Full service to all affected  customers  was
restored using  redundant  equipment on the satellite.  The redundant  equipment
currently generates a majority of Orion's revenues. Orion believes, based on the
data  received  to date by  Orion  from  its own  investigations  and  from  the
manufacturer,  and  based  upon  advice  from  Orion's  independent  engineering
consultant,  Telesat Canada, that because the redundant component is functioning
fully 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.  Furthermore,  there has been
no effect on Orion's ability to provide services to customers.  However,  in the
event that the redundant component fails, Orion 1 would experience a significant
loss of usable  capacity.  In such  event,  while  Orion  would be  entitled  to
insurance  proceeds of  approximately  $47  million and could lease  replacement
capacity  and  function  as  a  reseller  with  respect  to  such  capacity  (at
substantially reduced gross margins), the loss of capacity would have a material
adverse effect on Orion. See "Risk Factors -- Risks of Satellite Loss or Reduced
Performance."

   Control of Satellite. Orion uses its tracking, telemetry and command facility
in Mt.  Jackson,  Virginia (the "TT&C  facility") to control Orion 1, and has in
place backup facilities at its headquarters in Rockville, Maryland. In addition,
Orion has a  satellite  control  center at Orion's  headquarters  in  Rockville,
Maryland,  from  which  commands  can be sent  to the  satellite,  directly,  or
remotely  through  the TT&C  facility.  Orion  also has  constructed  a  network
management  center at its headquarters to monitor the performance of Orion 1 and
to  perform  diagnostic  procedures  on and to  reconfigure  its  communications
networks.  Orion leases  additional  facilities  in Europe for backup  tracking,
telemetry and command and network monitoring functions.

ORION 2

   Schedule and Footprint. Orion intends to launch Orion 2 in the Atlantic Ocean
region to bolster its European  capacity and to expand its coverage  area in the
Commonwealth of Independent States,  Latin America and parts of Africa.  Orion 2
will  be a high  power  Ku-band  communications  satellite  which  will  contain
approximately   30  transponders  of  54  MHz  bandwidth.   Orion  has  obtained
conditional  authorization  from  the FCC for the  orbital  slot at  12'  West
longitude  for  operation  of Orion 2. The FCC has  commenced  the  coordination
process  through  the ITU and will  commence  consultation  with  INTELSAT  upon
request from Orion.  Orion currently  plans to commence  construction of Orion 2
immediately  after  completion  of the  Offering  and launch Orion 2 late in the
second quarter of 1999. See "-- Satellite Construction,  Launch and Performance"
and "Risk  Factors  -- Launch  of Orion 2 and  Orion 3  Subject  to  Significant
Uncertainties."

[Document  contains a map of North America,  Latin America,  Europe,  Africa and
Asia showing in shaded areas the proposed coverage footprint of Orion 2]

   Satellite Construction,  Launch and Performance.  Matra Marconi Space and MMS
Space  Systems  are the  prime  contractors  for  Orion 2 and will use MMS Space
Systems' EUROSTAR  satellite  platform for Orion 2. This platform was previously
used for Inmarsat 2, Telecom 2, Hispasat and Orion 1.  Lockheed  Martin CLS will
provide launch services for Orion 2 using the Atlas II A-S launch vehicle. Atlas
II A-S,  which is larger than the launch vehicle used for the launch of Orion 1,
is an  expanded  version  of Atlas  II.  All 26 of the Atlas II, II A and II A-S
launches have been successful. There have been more than 500 Atlas flights since
the first  research and  development  launch in 1957.  For a  discussion  of the
Company's  financing  needs with  respect  to Orion 2, and  related  risks,  see
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations  -- Liquidity and Capital  Resources"  and "Risk Factors -- Launch of
Orion  2 and  Orion  3  Subject  to  Significant  Uncertainties  --  Substantial
Financing Requirements."

   The Orion 2  satellite  will be tested  extensively  prior to  launch.  Matra
Marconi  Space is  obligated  to correct  all  defects in the  satellite  or its
components discovered prior to the launch. If Orion 2 is launched

                                       65

<PAGE>
   
but fails to meet the specified  performance criteria following launch, or fails
to arrive at its  designated  orbit within 180 days of launch,  or is completely
destroyed  or  incapable of  operation,  Orion 2 will be deemed a  "constructive
total loss." Upon a constructive total loss of Orion 2, Orion would generally be
entitled  to  order  from  Matra  Marconi  Space  a  replacement   satellite  on
substantially  the  same  terms  and  conditions  as set  forth  in the  Orion 2
Satellite  Contract,  subject  to  certain  pricing  adjustments.  If Orion 2 is
substantially  able to  perform  but  fails to meet  certain  criteria  for full
acceptance,  Orion 2 will be deemed a  "partial  loss."  Upon a partial  loss of
Orion  2,  Orion  would  be  entitled  to  receive  a  partial  refund  based on
calculations  of  Orion  2's  performance  capabilities.  If  Orion  2 is  not a
constructive  total  loss or  partial  loss,  but does  not  meet the  specified
performance requirements at final acceptance or for five years thereafter, Matra
Marconi Space may be required to make certain  refund  payments to Orion up to a
maximum of approximately $10 million.  Orion's principal remedy in the case of a
constructive  total loss or partial loss will be under the launch  insurance the
Company is to obtain.  The Orion 2  Satellite  Contract  provides  Orion with an
option to purchase a replacement  satellite.  Under the  contract,  Orion has an
option to purchase a replacement satellite for Orion 2, to be delivered in orbit
no later than 21 1/4 months  after  Orion's  exercise of the option.  A total or
partial loss will involve delays and loss of revenue,  which will impair Orion's
ability to service its  indebtedness,  including the Notes,  and such  insurance
will not protect Orion against business interruption,  loss or delay of revenues
or similar losses and may not fully reimburse the Company for its  expenditures.
See  "Insurance"  below and "Risk Factors -- Risks of Satellite  Loss or Reduced
Performance -- Limited Insurance for Satellite Launch and Operation."
    
   The Orion 2 Satellite  Contract provides for incentive  payments to encourage
early  delivery  and  limited  liquidated  damages  payable in the event of late
delivery.  The incentive  payments would equal $25,000 per day for each day that
Orion 2 is delivered prior to the scheduled delivery date. Liquidated damages in
the event of a late  delivery  of Orion 2 also  would be  calculated  on a daily
basis, with the aggregate amount not to exceed approximately $12 million.  These
liquidated damages would be Orion's exclusive remedy for late delivery.

   Control of Satellite. Orion expects to use the TT&C facility to control Orion
2, and to use its existing network monitoring facilities in Rockville,  Maryland
and backup facilities in Europe.

   There can be no assurance that Orion 2 will be launched successfully. See
"Risk Factors -- Launch of Orion 2 and Orion 3 Subject to Significant
Uncertainties."

 ORION 3

   Schedule and  Footprint.  Orion intends to launch Orion 3 in the Asia Pacific
region.  Orion 3 is expected to cover all or  portions of China,  Japan,  Korea,
India, Hawaii, Southeast Asia, Australia, New Zealand, and Eastern Russia. Orion
3 is  expected  to be a  high-power  satellite  with  23 54 MHz  and  two 27 MHz
equivalent Ku-band transponders, 10 36 MHz C-band transponders for use by Orion,
and eight Ku-band transponders to be used by DACOM, a large Asian customer,  for
direct-to-home  television services and other satellite services. Orion, through
the Republic of the Marshall Islands, has filed the appropriate documentation to
begin the ITU process to  coordinate  an orbital slot at 139|SD East  longitude.
Orion has not commenced the  consultation  process with INTELSAT with respect to
such orbital slot.  Orion  commenced  construction  of Orion 3 in December 1996.
Orion 3 is  scheduled  to be launched in the fourth  quarter of 1998.  See "Risk
Factors -- Launch of Orion 2 and Orion 3 Subject to Significant Uncertainties."

   Pre-Construction  Customer.  Orion has  entered  into a  contract  with DACOM
Corp., a Korean  communications  company which provides  international  and long
distance  telephone and leased line  services,  international  and domestic data
communications and value added network services.  Under the contract, DACOM will
lease eight dedicated  transponders  on Orion 3 for 13 years for  direct-to-home
television   service  and   satellite   services,   in  return  for  payment  of
approximately $89 million payable over a period from December 1996 through seven
months following the lease commencement date for the transponders. DACOM has the
right to terminate  the  contract  before March 1997 (and Orion would retain the
$10 million paid) if it fails to obtain certain approvals.  Payments are subject
to refund if the successful launch and commencement of commercial  operations of
Orion 3 has not occured by June 30,  1999.  Although  Orion 3 is scheduled to be
launched in the fourth  quarter of 1998,  there can be no  assurance  that Orion
will meet the  delivery  requirements  of this  contract.  See "Risk  Factors --
Launch of Orion 2 and Orion 3 Subject  to  Significant  Uncertainties  -- Timing
Uncertainties."  As part of the arrangements  with DACOM,  Orion granted DACOM a
warrant to purchase 50,000 shares of Common Stock at $14 per share.

   Satellite  Construction,  Launch and  Performance.  Orion has selected Hughes
Space as the prime  contractor for Orion 3 and will use a Hughes Space HS 601 HP
satellite  platform  for Orion 3. Launch  services  for Orion 3 will be provided
using the McDonnell Douglas Delta III launch vehicle. Delta III,

which is larger  than the launch  vehicle  used for the launch of Orion 1, is an
expanded  version  of the Delta II launch  vehicle  which has had 53  successful
launches  with a failure rate of less than 4%. The most recent launch of a Delta
II (on January 17, 1997) resulted in launch explosion.  There have been no Delta
III flights to date,  and the  Company  expects its launch to be the third Delta
III flight based upon  information  provided by the launch vehicle  manufacturer
regarding  its present  flight  schedules.  For a  discussion  of the  Company's
financing  needs with respect to Orion 3, and related risks,  see  "Management's
Discussion  and Analysis of Financial  Condition  and Results of  Operations  --
Liquidity"  and "Risk  Factors  --  Launch  of Orion 2 and  Orion 3  Subject  to
Significant Uncertainties -- Substantial Financing Requirements."

   Under the Orion 3 Satellite  Contract,  the Orion 3 satellite  will be tested
extensively prior to launch. Hughes Space is obligated to correct all defects in
the satellite or its components discovered prior to the launch. The risk of loss
or  damage  to  Orion 3  passes  from  Hughes  Space  to  Orion  at the  time of
intentional  ignition  of Orion 3.  After  Orion 3 is  launched  and  meets  the
specified  performance  criteria  following launch,  and has not suffered damage
caused by any failure or  malfunction  of the launch  vehicle,  Hughes  Space is
required  to  perform  in-orbit  testing  of Orion 3 to  determine  whether  the
transponders meet the specified  performance  criteria. If the transponders meet
the specified performance criteria,  Hughes Space is entitled to retain the full
satellite  performance  payments  described  below. See "-- Insurance" and "Risk
Factors -- Risks of Satellite Loss or Reduced  Performance -- Limited  Insurance
for Satellite Launch and Operation."     

   Orion has an option to purchase an additional satellite (which may be used as
a  replacement  satellite)  to be  launched  within 12 to 19 months  after Orion
exercises  such option.  Orion must pay a fee if it exercises  this option;  the
size of the fee will depend on whether the  additional  satellite is required to
be  delivered  in 12, 15 or 19 months.  Hughes Space is obligated to furnish the
replacement  satellite on terms substantially  similar to those contained in the
Orion 3 Satellite Contract.

   The Orion 3 Satellite  Contract provides for incentive  payments to encourage
satellite  performance  and limited  liquidated  damages payable in the event of
late delivery.  The incentive  payments could total $18 million depending on the
satellite's  performance,  of which $10 million could be payable upon acceptance
of the Orion 3  satellite  and $8  million  is  payable  over the  course of the
satellite's  operational lifetime. In the event that it is determined during the
Orion 3's operational lifetime that a transponder is not successfully operating,
Orion is  entitled  to  receive  payment  refunds  under the  Orion 3  Satellite
Contract.  Liquidated  damages in the event of a late  delivery  of Orion 3 also
would be  calculated on a daily basis,  with the aggregate  amount not to exceed
approximately $6 million.  These liquidated  damages would be Orion's  exclusive
remedy for late delivery.

   Control of  Satellite.  Orion  expects  to lease a  tracking,  telemetry  and
command facility in Asia to control Orion 3 and to maintain backup facilities in
Korea, pursuant to arrangements with DACOM.

   There can be no  assurance  that Orion 3 will be launched  successfully.  See
"Risk  Factors  --  Launch  of  Orion  2 and  Orion  3  Subject  to  Significant
Uncertainties."

 ORBITAL SLOTS

   Orion  1.  Orion  has  been  licensed  by  the  FCC  and  has  completed  the
coordination  process with INTELSAT to operate Orion 1 in geostationary orbit at
37.5' West longitude.

   Orion 2. Orion has obtained  conditional  authorization  from the FCC for the
construction,  launch and operation of Orion 2 at 12' West longitude.  On behalf
of Orion,  the FCC has commenced the orbital slot  coordination  process through
the ITU.  Orion believes that its use of the 12' West longitude slot for Orion 2
is not likely to interfere  with  proposed  uses of adjacent  slots filed for by
other governments,  except for a possible overlap of 75 MHz with one such filing
as discussed more fully below under the caption "-- ITU  Coordination  Process."
Orion will  consult with  INTELSAT  regarding  Orion 2, and believes  that since
there are no INTELSAT  satellites  located  adjacent  to the 12' West  longitude
orbital slot, the INTELSAT coordination should be obtained in due course.

   Orion 3. Orion,  through the Republic of the Marshall Islands,  has filed the
appropriate documentation with the ITU to begin the ITU coordination process for
Orion 3 at 139' East longitude. Based

                                       68

<PAGE>

upon the time of filing by the Republic of the Marshall Islands,  Orion believes
that the proposed  orbital slot for Orion 3 would have effective  priority under
ITU procedures  with respect to the 139' East  longitude  orbital slot, but some
proposals  for adjacent  slots would be entitled to priority  over the Company's
proposal (through the Republic of the Marshall Islands) with respect to possible
interference.  Orion believes,  based upon its monitoring of the other proposals
and  information  in the industry  regarding  their  progress,  that none of the
entities  with  effective  priority  over the  Company's  proposal  (through the
Republic of the Marshall  Islands)  will be able to launch a satellite  prior to
launch of Orion 3 to take  advantage of such  priority.  Orion has not commenced
the  consultation  process with  INTELSAT with respect to Orion 3, but as in the
case of Orion 2 expects to complete the INTELSAT coordination in due course.

   Other Orbital Slots.  Orion has received an authorization  from the FCC for a
Ku-band  satellite  in  geostationary  orbit  at 47'  West  longitude,  and  has
coordinated  this  orbital  position  with  INTELSAT.  Orion  has also  filed an
application with the FCC to operate a satellite at 126' East longitude.  The FCC
has filed  documentation  with the ITU to commence the coordination  process for
this slot. In May 1996, in response to Orion's application, the FCC assigned the
U.S.  domestic  orbital  location of 135' West  longitude to Orion.  In November
1996, the FCC granted authorization to Orion to utilize the slot, conditioned on
Orion  submitting   financial   qualification   information,   or  documentation
justifying  a waiver of the  financial  requirements,  within 120 days after the
release of the  individual  order with  respect  to Orion's  application.  Orion
presently intends to seek a waiver with respect to this 120-day requirement, but
believes failure to obtain a waiver would not have a material affect on Orion or
its  business.   Such  120-day  requirement  does  not  apply  to  authorization
previously  granted to Orion,  such as for the 12' West  longitude  orbital slot
proposed to be used for Orion 2.

   In September  1995,  Orion filed  applications  for  authority to  construct,
launch  and  operate  Ka-band  satellites  at 78.0' East  longitude,  93.0' West
longitude, and 83.0' West longitude, and an amendment to its pending application
to construct,  launch and operate a Ku-band  satellite at 127' West longitude to
add a Ka-band  payload.  In addition,  Orion filed an  application to modify its
authority  to  construct,  launch and  operate a Ku-band  satellite  at 47' West
longitude  to include a  North/South  beam  configuration.  On November 9, 1995,
Orion filed an  application  for  authority to  construct,  launch and operate a
Ka-band  satellite at 12' West longitude.  In May 1996, the FCC assigned Ka-band
orbital  locations for 33 U.S.  companies for international  orbital  locations,
including two assigned to Orion at 78' East longitude and 126.5' East longitude,
and one at 47' West longitude. This orbital assignment plan was conditioned upon
authorization  of the domestic  portion of the proposed  satellite  systems.  At
approximately the same time the FCC made ITU filings for these  satellites.  The
FCC order does not license these satellites, and some of the applications to use
the orbital assignments are subject to further FCC processing. There are ongoing
negotiations  among the  applicants  concerning  a  consensual  Ka-band  orbital
assignment  plan to be  submitted  to the FCC to  resolve a number  of  mutually
exclusive  orbital  assignment  requests,   including  Orion's  pending  Ka-band
application  for  93.0'  West  longitude,  83.0'  West  longitude  and 127' West
longitude.  The FCC has indicated  that if a consensus  cannot be reached by the
applicants,  the  FCC  will  itself  resolve  these  orbital  conflicts  in  the
processing of these applications, and such processing will be in conformity with
yet-to-be  adopted Ka-band  service rules.  There can be no assurance that Orion
will receive final licenses to operate at these orbital  positions,  or that the
FCC will act favorably on Orion's other satellite filings.

   ITU Coordination  Process. An international  treaty to which the U.S. and the
Republic of the Marshall Islands are parties requires  coordination of satellite
orbital slots through the procedures of the ITU. There are only a limited number
of such  orbital  slots.  ITU  procedures  provide  for a priority  to attach to
proposals that are submitted first for a particular  orbital slot and associated
frequencies,  and provide for  protection  from  interference  by  satellites in
adjacent slots. This priority does not establish  legally-binding rights, but at
a minimum  establishes  certain  procedural  rights and obligations for and with
respect to the party that first submits its proposal.

   Over  the  past  decade,  a  substantial   increase  in  satellite  proposals
introduced into the ITU coordination  process has caused delays in that process.
In  addition,  many  proposals  are  submitted  to the ITU for  registration  of
satellite systems that ultimately are not constructed or launched.  As a result,
the ITU is  investigating  ways to improve or streamline  the filing process for
registration of orbital slots. In the

                                       69

<PAGE>

meantime, it has become international  practice for operators who propose to use
a certain orbital slot to investigate and evaluate  whether  proposals to launch
satellites  into the same or a nearby  orbital  location are likely to result in
actual  operation,  and for  operators  to  negotiate  with other  countries  or
operators that propose to use the same or a nearby orbital  location.  There can
be no assurance of the outcome of any objections to this international  practice
or as to the results of the ITU's investigations.

   Orion is involved in discussions  with certain  governments  concerning their
proposals to use orbital slots.  While Orion  believes that it can  successfully
coordinate  and  resolve  any  interference  concerns  regarding  the use of the
orbital  locations and frequency  bands  proposed for Orion 2 and Orion 3, there
can be no assurance that this will be achieved,  nor can there be assurance that
ITU coordination will be completed by the scheduled launch dates for Orion 2 and
Orion 3.

   In the event that successful coordination cannot be achieved,  Orion may have
to modify the  satellite  design for Orion 2 or Orion 3 in order to minimize the
extent of any potential  interference with other proposed satellites using those
orbital  locations  or frequency  bands.  Any such  modifications  may result in
certain  features of Orion 2 and Orion 3 differing from those  described in this
Prospectus and may result in limitations on the use of one or more  transponders
on Orion 2 or Orion 3 or delays in the launch of Orion 2 or Orion 3. In order to
achieve successful coordination,  Orion may also have to modify the operation of
the satellites,  or enter into commercial  arrangements  with operators of other
satellites,  in  order  to  protect  against  harmful  interference  to  Orion's
operations.  If interference  occurs with satellites that are in close proximity
to Orion 2 and Orion 3, or with satellites that are  subsequently  launched into
locations in close proximity  without  completing ITU  coordination  procedures,
such  interference  would  have an  adverse  effect on the  proposed  use of the
satellites and on Orion's business and financial performance.  See "Risk Factors
- -- Approvals Needed; Regulation of Industry."

 APPRAISAL

   Ascent Communications Advisors, L.P. ("Ascent") has delivered an appraisal to
the Company  valuing  Orion 1 at  approximately  $304  million as of December 1,
1996. In preparing this  appraisal  Ascent took into  consideration  the design,
location and capability of Orion 1, supply and demand for  transponders  and the
market  size and growth in each  market  Orion  Atlantic  is serving or plans to
serve and the principal competition and revenues and operating costs of Orion 1.
Ascent's  appraisal was based on projecting and  discounting  transponder  lease
rates,  adjusted for appropriate  costs, to derive the present value of the cash
flows  associated  with the  ownership of the  transponder  capacity of Orion 1.
Ascent  considered  but rejected the use of  replacement  cost  because,  in its
experience,  in-orbit transponders often trade at prices substantially in excess
of replacement cost. Ascent also noted that the most accurate way to value Orion
1 would be to identify  recent,  closely  comparable  sales of  transponders  or
satellites serving similar markets.  Ascent did not use this method since it was
unable to identify any closely comparable sales. However,  Ascent's did identify
the most comparable  satellite sales as a check on approach in appraising  Orion
1.

   Because events and circumstances  frequently do not occur as expected and for
the reasons  described  under "Risk  Factors" and elsewhere in this  Prospectus,
there will usually be differences between assumed and actual results,  and those
differences  may be  material.  Therefore,  no  assurance  may be given that the
appraised value of Orion 1 will be achieved and reliance should not be placed on
such appraised value.

   The Company has obtained an appraisal  from Ascent  because it believes  that
the value of Orion 1 may be of interest to  purchasers of the Notes as creditors
of the  Company,  and that  such  purchasers  might be  interested  in an expert
appraiser's assessment of the value of Orion 1.

 INSURANCE

   Orion has obtained satellite in-orbit life insurance for Orion 1 covering the
period  from May 1996 to May 1997 in an  initial  amount of  approximately  $245
million  providing  protection  against partial or total loss of the satellite's
communications capability,  including loss of transponders,  power or ability to
control the  positioning  of the satellite.  The aggregate  premium for in-orbit
insurance for Orion 1 is approximately $6 million per annum.

                                       70

<PAGE>

   
   Orion intends to procure launch  insurance for the  construction,  launch and
insurance costs of Orion 2 and Orion 3. In the past,  satellite launch insurance
was generally procured  approximately six months prior to launch.  Recently,  it
has become  possible to obtain a commitment  from  insurance  underwriters  well
before that time,  which fixes the rate and certain  terms of launch  insurance.
Orion intends shortly to seek such a commitment  from insurance  underwriters to
provide launch  insurance for Orion 2 and Orion 3. Such insurance is expected to
be quite  costly,  with present  insurance  rates ranging at or above 16% of the
insured  amount,  depending  upon such factors as the launch  history and recent
performance of the launch vehicle to be used and general  availability of launch
insurance in the insurance  marketplace (although such rates have reached 20% or
higher in the past several  years).  Such  insurance  can be expected to include
certain contract terms,  exclusions,  deductibles and material change conditions
that are  customary  in the  industry.  After launch of Orion 2 and Orion 3, the
Company will need to procure  satellite  in-orbit life insurance for Orion 2 and
Orion 3. There can be no assurance that such insurance will be available or that
the price of such insurance or the terms and exclusions in the actual  insurance
policies will be favorable to the Company. Launch and in-orbit insurance for its
satellites will not protect the Company against business  interruption,  loss or
delay of revenues and similar losses and may not fully reimburse the Company for
its expenditures.  Accordingly,  an unsuccessful launch of Orion 2 or Orion 3 or
any significant  loss of performance with respect to any of its satellites would
have a material  adverse  effect on Orion and would  impair  Orion's  ability to
service its indebtedness,  including the Notes, and on the value of the Warrants
and  Common  Stock.  See "Risk  Factors  -- Risks of  Satellite  Loss or Reduced
Performance -- Limited Insurance for Satellite Launch and Operation."     

COMPETITION

   As a  provider  of  data  networking  and  Internet-related  services,  Orion
competes  with a  large  number  of  telecommunications  service  providers  and
value-added  resellers  of  transmission  capacity.  As a provider of  satellite
transmission  capacity,  Orion  competes  with other  providers of satellite and
terrestrial facilities.

   Many of these competitors have significant competitive advantages,  including
long-standing  customer  relationships,  close  ties with  regulatory  and local
authorities,  control  over  connections  to local  telephone  networks and have
financial  resources,  experience,  marketing  capabilities and name recognition
that are  substantially  greater than those of Orion.  The Company believes that
competition in emerging  markets will intensify as incumbent  service  providers
adapt to a competitive  environment and  international  carriers  increase their
presence in these  markets.  The Company also believes that  competition in more
developed markets will intensify as larger carriers  consolidate,  enhance their
international  alliances and increase  their focus on data  networking.  Orion's
ability  to  compete  with these  organizations  will  depend in part on Orion's
ability to price its services at a significant  discount to terrestrial  service
providers,  its  marketing  effectiveness,  its level of  customer  support  and
service and the technical advantages of its systems.

 SERVICE PROVIDERS

   Orion has encountered strong competition from major established carriers such
as AT&T, MCI,  Sprint,  British  Telecom,  Cable & Wireless,  Deutsche  Telekom,
France Telecom and Kokusai Denshin Denwa, which provide international telephone,
private  line and  private  network  services  using  their  national  telephone
networks and link to those of other  carriers.  A number of these  carriers have
formed global consortia to provide private network  services,  including AT&T --
Unisource Services Company (AT&T, PTT Telecom Netherlands, Telia (Sweden), Swiss
Telecom PTT and  Telefonica of Spain),  Concert  (British  Telecom and MCI), and
Global  One  (Sprint,  France  Telecom  and  Deutsche  Telekom).  Other  service
providers  include MFS Worldcom (which acquired IDB  Communications  Group, Inc.
and  Wiltel  International,   Inc.),  Infonet,  SITA,  Telemedia  International,
Spaceline,  ANT Bosch (which is being  acquired by General  Electric),  Teleport
Europe,  Impsat,  and various local  resellers of satellite  capacity.  Finally,
service organizations that purchase satellite capacity,  VSAT and other hardware
and install their own networks may be considered competitors of the Company with
respect to their own

                                       71

<PAGE>

networks.  Although these carriers and service  providers are competitors,  some
are also Orion's  customers.  Orion believes that all network service  providers
are potential users of Orion's satellite  capacity for the network services they
offer  their  customers.  See "Risk  Factors  --  Potential  Adverse  Effects of
Competition."

 SATELLITE CAPACITY

   
   Orion  provides fixed  satellite  service and does not intend to compete with
most proposed  mobile  satellites or mobile low earth orbit systems ("LEO") such
as Globalstar,  Iridium or Odyssey (although the Company expects to compete with
Teledesic,  a proposed LEO  system),  or, with the  exception of the  pre-leased
transponders on Orion 3 to be used for video transmissions,  with direct-to-home
satellite  systems such as  Primestar,  DirectTV or EchoStar.  Mobile  satellite
services are  characterized  by voice and data  transmission  to and from mobile
terminals on platforms  such as ships or aircraft.  Direct-to-home  services are
characterized  by the  transmission  of television  and  entertainment  services
directly to consumers. Orion's satellites will compete with trans-Atlantic fixed
satellite  systems,  European  regional and domestic  systems and Asian systems.
    

   Existing  International and Trans-Atlantic  Satellite Systems. The market for
international  fixed  satellite  communications  capacity has been  dominated by
INTELSAT for thirty years,  and INTELSAT can be expected to continue to dominate
this market for the foreseeable future.  INTELSAT, a consortium of approximately
140 countries established by international treaty in 1964, owns and operates the
largest  fleet  of  commercial   geosynchronous  satellites  in  the  world  (25
satellites,  with additional  satellites on order).  INTELSAT's  satellites have
historically  been general  purpose,  lower-power  satellites  designed to serve
large areas with public telephone service  transmitted between expensive gateway
earth stations. INTELSAT generally provides capacity directly to its signatories
who then  market such  capacity  to their  customers.  The  availability  of new
services generally is subject to the discretion of each country's  signatory and
INTELSAT is required  under its charter to set its pricing in order to achieve a
fixed  pre-tax  return  on  equity  that  is  established  from  time to time by
INTELSAT's board of governors. INTELSAT is considering a restructuring and it is
expected  that the Intelsat  Assembly of Parties will decide on a new  structure
for the  organization in 1997. Any  restructuring of INTELSAT that increases its
marketing  flexibility could materially impact Orion's ability to compete in the
market for private satellite delivered services.

   PanAmSat  currently  operates four satellites,  with one satellite  providing
coverage in each of the  Atlantic  Ocean  region,  the Asia  Pacific  region and
Indian Ocean region (the fourth covers the Atlantic Ocean region but is near the
end of  its  useful  life).  These  satellites  primarily  provide  broadcasting
services,  such  as  television  programming  and  backhaul  operations.  PAS 3,
launched in January 1996, with coverage of the Atlantic Ocean, competes directly
with Orion 1. It has performance  attributes  which are generally  comparable to
those of Orion 1 and carries 16 Ku-band  transponders,  of which 8  transponders
are  capable  of  providing   service  to  or  within  Europe,   and  16  C-band
transponders.  PanAmSat has announced that it intends to launch four  additional
satellites,  two in 1997 that will provide coverage of the U.S., Central America
and Mexico,  and two that will provide  coverage of the Indian and Pacific Ocean
regions,  respectively,  in 1997 and early  1998.  PanAmSat is in the process of
selling a controlling interest to Hughes Electronics Corp., which is the largest
private  space-related  company  in the world.  This  transaction  will  enhance
PanAmSat's ability to compete with Orion.

   Existing European Regional and Domestic Satellite Systems.  In Europe,  Orion
competes with certain regional  satellites systems and may compete with domestic
satellite  systems.  Regional  and domestic  satellite  systems  generally  have
limited  ability  to serve  customers  with  needs for  extensive  international
networks.  Orion's primary  competitor in Europe is the major regional satellite
system operated by EUTELSAT. EUTELSAT,  established in 1977, presently comprises
over  approximately 45 member  countries.  EUTELSAT  operates seven  satellites,
providing telephony,  television,  radio and data services,  and has announced a
plan to launch five new satellites through 1998.

   Asian   Pacific    Region    Satellite    Systems.    Orion   believes   that
currently-operating  satellite  systems in the Asia Pacific region generally are
limited in their ability to provide private  network and similar  services at an
acceptable performance level due to insufficient power, limited Ku-band capacity
and

                                       72

<PAGE>

limited geographic coverage.  Nevertheless, there is a large number of satellite
systems  operating in Asia. The major Asia Pacific  regional  satellite  systems
include  the  AsiaSat  system  licensed  in Hong Kong  (with two  satellites  in
operation  and a third  planned for launch in 1997),  the Chinese  Apstar system
(also with two  satellites  in operation and a third planned for launch near the
end of 1997) and the  Indonesian  Palapa system (with three  satellites in orbit
and plans to launch at least  three more  satellites  through  1999).  Japan has
licensed  several  satellite  networks for domestic and  international  service,
including the JCSat series (three  satellites in operation and a fourth  planned
for  launch in 1997),  NTT's two  N-Star  satellites,  and Space  Communications
Corporation's  Superbird A and B (with a third planned for 1997). Optus operates
four Australian  domestic satellites that offer limited  international  coverage
and  plans  several  follow-on  satellites.  Korea  operates  Koreasat  1 and 2,
primarily  for domestic  service,  with plans for a third  satellite  that would
offer  expanded  regional  service in 1999.  Thailand  has  licensed the Thaicom
system, with two domestic satellites in operation,  and plans two new satellites
in  1997  offering  regional  coverage.   Measat  operates  a  Malaysian  system
consisting  of two  satellites  providing  DTH service to Malaysia  and parts of
Asia.

   Other Satellite  Systems.  There are numerous  satellites other than the ones
discussed above that compete to some extent with Orion. In addition, the Company
is aware of a substantial  number of satellites  that are in  construction or in
the  planning  stages.  Most of these  satellites  will cover  areas  within the
footprint of Orion 1 and/or the proposed  footprints  of Orion 2 and Orion 3. As
these  new  satellites  commence   operations,   they  (other  than  replacement
satellites   not   significantly   larger  than  the  ones  they  replace)  will
substantially increase the capacity available for sale in the company's markets.
After a satellite has been successfully delivered in orbit, the variable cost of
transmitting additional data via the satellite is limited. Accordingly, absent a
corresponding increase in demand, this new capacity can be expected to result in
significant  additional price  reductions.  For example,  Teledesic  Corporation
proposes  to  operate  up to 840 low earth  orbit  small  satellites  by 2001 to
provide  global  satellite   services   (including  voice,  data  and  broadband
transmission  services).  Although  Orion cannot assess to what degree,  if any,
these  proposed  satellites  might  compete with Orion in the future,  Teledesic
could  provide  significant  competition  to the Company.  See "Risk  Factors --
Potential Adverse Effects of Competition."

 TERRESTRIAL CAPACITY

   Orion   competes   with   terrestrial   facilities   for   intra-Europe   and
trans-Atlantic capacity.

   European    Facilities.    Orion's    services   compete   with   terrestrial
telecommunications delivery services, which are being improved gradually through
the  build-out  of fiber  optic  networks  and a move  from  analog  to  digital
switching.   As  fiber  networks  and  digital  network  switching  become  more
prevalent,  the resulting  improved and less expensive  terrestrial  capacity is
increasingly competitive with Orion's services.

   Undersea   Cable.   Undersea   fiber  optic  cable   capacity  has  increased
substantially  in recent years.  Although  Orion  believes  that undersea  cable
capacity is not as well suited as satellite  capacity to serve the  requirements
of video  broadcasters or the demand for multi-point  private network  services,
fiber optic and coaxial  cables are well suited for  carrying  large  amounts of
bulk traffic,  such as long distance  telephone  calls,  between two  locations.
Operators of undersea  fiber optic cable systems  typically  are joint  ventures
among major telecommunications  companies. Orion expects strong competition from
these carriers in providing private network services.

REGULATION

REGULATORY OVERVIEW

   The international  telecommunications  environment is highly regulated. As an
operator of privately  owned  international  satellite  systems  licensed by the
United States, Orion is subject to the regulatory authority of the United States
(primarily the FCC) and the national communications authorities of the countries
in which it provides  service.  Each of these  entities can  potentially  impose
operational restrictions on Orion. In addition, Orion is subject to the INTELSAT
and EUTELSAT consultation processes.

                                       73

<PAGE>

The changing  policies and  regulations of the United States and other countries
will continue to affect the  international  telecommunications  industry.  Orion
cannot  predict  the impact  that these  changes  will have on its  business  or
whether the general  deregulatory  trend in recent  years will  continue.  Orion
believes  that  continued   deregulation  would  be  beneficial  to  Orion,  but
deregulation  also could  reduce the  limitations  facing  many of its  existing
competitors and potential new competitors.

   The  operation  of Orion 2 and Orion 3 will  require  a number of  regulatory
approvals, including (i) the approvals of the FCC (in the case of Orion 2), (ii)
completion of successful  consultations  with INTELSAT and, in the case of Orion
2, with EUTELSAT;  (iii)  satellite  "landing"  rights in countries that are not
INTELSAT  signatories or that require additional  approvals to provide satellite
or VSAT services;  and (iv) other regulatory approvals.  Obtaining the necessary
licenses and approvals  involves  significant  time and expense,  and receipt of
such licenses and approvals cannot be assured.  Failure to obtain such approvals
would have a material  adverse effect on Orion and on its ability to service its
indebtedness,  including  the Notes,  and the value of the  Warrants  and Common
Stock. In addition, Orion is required to obtain approvals from numerous national
local authorities in the ordinary course of its business in connection with most
arrangements  for the provision of services.  Within Orion 1's  footprint,  such
approvals  generally  have not been  difficult  for  Orion to obtain in a timely
manner.  However, the failure to obtain particular approvals has delayed, and in
the future may delay,  the provision of services by Orion.  See "Risk Factors --
Approvals Needed; Regulation of Industry."

AUTHORITY TO CONSTRUCT, LAUNCH AND OPERATE SATELLITES

   Orion 1. In June 1991, Orion received final  authorization  from the FCC (the
"Orion 1  License")  to  construct,  launch and operate a Ku-band  satellite  in
geostationary  orbit at 37.5'  West  longitude  in  accordance  with the  terms,
conditions and technical specifications submitted in its application to the FCC.
The Orion 1 license from the FCC expires in January 2005.  Although Orion has no
reason  to  believe  that its  licenses  will not be  renewed  (or new  licenses
obtained) at the  expiration of the license  term,  there can be no assurance of
renewal.

   Orion 2. Orion has obtained  conditional  authorization  from the FCC for the
orbital  slot at 12' West  longitude  for  operation  of  Orion  2. The  Orion 2
authorization  will not become final until Orion  completes a consultation  with
INTELSAT and demonstration to the FCC of its financial ability to meet the costs
of construction, the launch of its satellite and operating expenses for one year
following launch.  Orion has not yet met the required  financial  qualifications
demonstration  to the FCC. It is required  to make such  showing  within 90 days
after completion of INTELSAT  consultation,  and accordingly intends to commence
consultation  with  INTELSAT  after it has  obtained  additional  financing  and
believes it can make the required financial showing.  The application filed with
the FCC for Orion 2 contains a technical  proposal different than that currently
being coordinated with the ITU, and will need to be amended. Orion has no reason
to believe  that the FCC will not approve such  amendment or that the  amendment
will cause material delay in obtaining final FCC authority for Orion 2.

   Orion 3. Orion is pursuing an orbital slot at 139' East longitude through the
Republic of the Marshall  Islands.  Under an agreement  with the Republic of the
Marshall  Islands  entered into in 1990,  the  Republic of the Marshall  Islands
agreed to file with the ITU all documents necessary to secure  authorization for
Orion to operate a satellite in geo-stationary orbit. In return for the right to
utilize any orbital slots secured by the Republic of the Marshall Islands, Orion
must, among other things, (i) commence  construction of a functioning  operating
center for  satellites  serving  the  Pacific  Island  portion of the Orion Asia
Pacific  network at least a year prior to the  operation of an Orion  satellite,
(ii) train and  support  certain  employees  designated  by the  Republic of the
Marshall Islands at least a year prior to the operation of an Orion Asia Pacific
satellite,  and (iii)  construct,  equip and install (except for power supply or
back-up) four earth  stations  capable of handling a "T-1" circuit for operation
with the Orion  Asia  Pacific  system  prior to the  operation  of an Orion Asia
Pacific satellite.

CONSULTATION WITH INTELSAT AND EUTELSAT

   Orion 1. Prior to receiving final licensing and launch authority for Orion 1,
Orion  successfully  completed its  consultation  with INTELSAT  pursuant to the
INTELSAT Treaty. A similar consultation

                                       74

<PAGE>

for Orion 1 was completed with EUTELSAT in May 1994. Additional consultations or
other approvals may be needed in individual countries for the use of VSATs.

   Orion 2. Orion has not commenced  consultations with INTELSAT or EUTELSAT for
Orion 2, and intends to commence  such  consultation  with  INTELSAT for Orion 2
when it is ready to make its financial  showing to the FCC, as discussed  above.
Orion believes that since there are no INTELSAT or EUTELSAT  satellites  located
adjacent  to  the  12'  West   longitude   orbital   slot,   the   INTELSAT  and
EUTELSATcoordination should be obtained in due course.

   Orion 3. Orion has not commenced consultations with INTELSAT for Orion 3, but
Orion believes that since there are no INTELSAT  satellites  located adjacent to
the 139' East  longitude  orbital  slot,  the  INTELSAT  coordination  should be
obtained in due course.

INTERNATIONAL TELECOMMUNICATION UNION

   An  international  treaty to which the U.S.  and the Republic of the Marshall
Islands are parties requires coordination of satellite orbital slots through the
procedures  of the ITU. The process for  coordinating  orbital slots through the
ITU is  discussed  under the  caption  " --  Orbital  Slots -- ITU  Coordination
Process."

   Orion 1. After Orion 1 reached its orbital position and commenced  operation,
the FCC notified the ITU.  This  concluded the process for  coordination  of the
Orion 1 orbital slot.

   Orion  2. On  behalf  of  Orion,  the  FCC has  commenced  the  orbital  slot
coordination  process  through the ITU.  Orion  believes that its use of the 12'
West longitude slot for Orion 2 is not likely to interfere with proposed uses of
adjacent slots filed for by other governments,  except for a possible overlap of
75 MHz with one proposal as  discussed  more fully under the caption "-- Orbital
Slots -- ITU Coordination Process."

   Orion 3. Orion,  through the Republic of the Marshall Islands,  has filed the
appropriate documentation with the ITU to begin the ITU coordination process for
Orion 3 at 139' East  longitude.  As discussed  more fully under the caption "--
Orbital Slots -- ITU Coordination Process," based upon the time of filing by the
Republic of the Marshall Islands,  Orion believes that the proposed orbital slot
for Orion 3 would have priority  under ITU  procedures  with respect to the 139'
East longitude  orbital slot, but some  proposals by other  administrations  for
adjacent slots would be entitled to effective  priority over the proposal by the
Republic of the Marshall  Islands with respect to possible  interference.  Orion
believes,  based upon its  monitoring of the proposals of other  administrations
and  information  in the industry  regarding  their  progress,  that none of the
administrations with effective priority over the proposal by the Republic of the
Marshall  Islands will be able to launch a satellite  prior to launch of Orion 3
to take advantage of such priority. Orion also believes that it can complete the
ITU coordination process for Orion 3 at 139' East longitude,  however, there can
be no assurance that this will be achieved.

UNITED STATES REGULATORY RESTRICTIONS

   Orion is subject to regulation under the  Communications  Act, the FCC's July
1985 Separate  Systems  decision as modified by subsequent FCC decisions,  other
FCC  regulations,  and the terms of the  various  orders  issued by the FCC with
respect  to Orion  and its  subsidiaries,  including  the  terms of the  Orion 1
License.   These   regulations,   orders  and   authorizations   impose  various
restrictions  on  Orion  and on  other  similarly  situated  companies.  Certain
important restrictions are described below.

   Limited Interconnection with Public Switched Message Networks.  Under current
U.S. policies concerning "separate satellite systems," such systems may provide:
(i) all services not  interconnected  with the public switched  network ("PSN");
(ii) emergency  restoration services and up to 8,000 64 kbps equivalent circuits
per satellite  interconnected  with the PSN for common carrier  public  switched
international  services; and (iii) interconnected  private line services.  Under
applicable FCC orders,  Orion has been authorized to provide up to 8,000 64 kbps
equivalent circuits  interconnected to the PSN for public switched services. All
U.S.  restrictions  on the  interconnection  of public  switched  networks  with
separate  satellite  systems are expected to  terminate in the first  quarter of
1997. Orion's networking business is

                                       75

<PAGE>

intended  to be  non-common  carrier  service,  and  accordingly  it will not be
permitted to provide interconnected  switched services, but will be permitted to
sell this capacity to common carriers.

   Use of the Orion 1 Satellite System for U.S.  Domestic  Services.  In January
1996, the FCC eliminated  certain  distinctions  between U.S.  licensed domestic
satellites  and separate  satellite  systems.  It  authorized  both sets of U.S.
licensed  satellite   operators  to  provide  both  domestic  and  international
services.  Domestic  operators have designed their current satellite  facilities
principally for continental U.S. coverage of the United States,  and thus may as
a general matter offer only limited  competition for  international  services at
the outset.  However,  future satellite designs of domestic satellite  operators
could be modified to more directly compete in the international market.

   New Orbital Locations. The FCC now requires applicants, at the time of filing
for an orbital position (either domestic arc or international orbital position),
to  demonstrate  the  financial  ability to  construct,  launch and operate that
satellite for a one year period. This new requirement will have no change in the
licensing  of  Orion's  orbital  positions  at 37.5'  West,  12' West,  47' West
longitude and 126' East  longitude  (the orbital slot at 139' East  longitude is
not being pursued  through the FCC and is not subject to the  financial  showing
requirement).  To the extent that Orion is seeking an orbital  location  through
the FCC,  Orion will need to have  significant  financing on hand at the time of
application or obtain a waiver of the required financial demonstration. There is
no assurance that Orion will be able to obtain such waiver.

   Unauthorized  Transfer of Control.  The  Communications  Act bars a change in
control of the holder of FCC licenses  without prior  approval from the FCC. Any
finding that a change of control  without prior FCC approval had occurred  could
have a significant  adverse effect on Orion's  ability to implement its business
plan.

INTERNATIONAL REGULATION

   Orion will need to comply with the applicable laws and obtain the approval of
the regulatory authority of each country in which it proposes to provide network
services  or operate  VSATs.  The laws and  regulatory  requirements  regulating
access to satellite  systems vary from country to country.  Some  countries have
substantially  deregulated satellite  communications,  making customer access to
Orion  services  a simple  procedure,  while  other  countries  maintain  strict
monopoly regimes.  The application  procedure can be time-consuming  and costly,
and the terms of licenses vary for different countries.

   Orion provides  service using the licenses it obtains or that are obtained by
local  ground  operators  or,  in  certain  cases,   through   customer-obtained
authorizations.  For  example,  Orion's  representatives  in the United  Kingdom
(Kingston  Communications),  France (Matra Hachette),  Germany (Nortel Dasa) and
Italy (Telecom Italia) have licenses in such countries.  Orion also has obtained
"landing rights" through the INTELSAT treaty  (although each INTELSAT  signatory
country  retains  sovereignty  over the  transmission  of satellite  signals and
retains the right to object to the use of satellites within its borders).  Orion
is now authorized,  either directly or through its ground operators,  to provide
service in 27 European countries.

   Orion  expects to pursue a similar  strategy  in Asia and Latin  America.  In
addition,  Orion will need to comply with the  national  laws of each country in
which it  provides  services.  Laws  with  respect  to  satellite  services  are
currently  unclear in  certain  jurisdictions,  particularly  within the Orion 3
footprint.  In certain of these  jurisdictions,  satellite  services may only be
provided via domestic  satellites.  The Company  believes  that certain of these
restrictions  may change and that it can structure its operations to comply with
the remaining  restrictions.  However, there can be no assurance in this regard.
See "Risk Factors -- Approvals Needed; Regulation of Industry."

HUMAN RESOURCES

   As of  October  31,  1996,  Orion  and its  subsidiaries  had  175  full-time
employees.  Of its  total  work  force,  six are part of  management,  44 are in
engineering  or satellite  control  operations,  75 are in marketing,  sales and
sales support, and 50 are devoted to support and administrative activities.

LEGAL PROCEEDINGS

   In October 1995, Skydata Corporation ("Skydata"), a former contractor,  filed
suit against Orion  Atlantic,  Orion  Satellite  Corporation  and Orion,  in the
United States District Court for the Middle  District of Florida,  claiming that
certain Orion Atlantic  operations using frame relay switches infringe a Skydata
patent.  Skydata's  suit sought  damages in excess of $10 million and asked that
any damages assessed be trebled. On December 11, 1995, the Orion parties filed a
motion to  dismiss  the  lawsuit  on the  grounds  of lack of  jurisdiction  and
violation of a mandatory  arbitration  agreement.  In addition,  on December 19,
1995, the Orion parties filed a Demand for Arbitration  against Skydata with the
American  Arbitration  Association in Atlanta,  Georgia,  requesting  damages in
excess of $100,000 for breach of contract and declarations,  among other things,
that Orion and Orion Atlantic own a royalty-free license to the patent, that the
patent is invalid and  unenforceable  and that Orion and Orion Atlantic have not
infringed  on the patent.  On March 5, 1996,  the court  granted  the  Company's
motion to dismiss the lawsuit on the basis that Skydata's  claims are subject to
arbitration.  Skydata  appealed  the  dismissal  to the United  States  Court of
Appeals  for the  Federal  Circuit.  Skydata  also filed a  counterclaim  in the
arbitration  proceedings asserting a claim for $2 million damages as a result of
the conduct of Orion and its affiliates. On May 15, 1996, the arbitrator granted
the Orion  parties'  request  for an initial  hearing on claims  relating to the
Orion parties' rights to the patent,  including the co-ownership claim and other
contractual claims.

   On November 9, 1996,  Orion and Skydata executed a letter with respect to the
settlement  in full  the  pending  litigation  and  arbitration.  As part of the
settlement, the parties are to release all claims by either side relating in any
way to the patent and/or the pending  litigation and  arbitration.  In addition,
Skydata  is to grant  Orion (and its  affiliates)  an  unrestricted,  world-wide
paid-up  license to make,  have made,  use or sell products or methods under the
patent and all other corresponding continuation and reissue patents. Orion is to
pay Skydata  $437,000 over a period of two years as part of the settlement.  The
parties  are in the  process of  documenting  the terms of the  settlement  in a
formal settlement agreement.

   While Orion is party to  regulatory  proceedings  incident  to its  business,
there  are no  material  legal  proceedings  pending  or,  to the  knowledge  of
management, threatened against Orion or its subsidiaries.

COMMITTEES OF THE BOARD OF DIRECTORS

   The Board of Directors  has  established  a Committee on Auditing,  Corporate
Responsibility  and  Ethics  (the  "Audit  Committee"),  a  Committee  on  Human
Resources  and  Compensation  (the  "Compensation   Committee"),   an  Executive
Committee, a Finance Committee and a Nominating Committee.

   The Audit Committee is composed of Messrs.  Van Degna (chairman),  Hauser and
Kahn.  The Audit  Committee  examines  and  considers  matters  relating  to the
financial  affairs  of  Orion,  including  reviewing  Orion's  annual  financial
statements,  the  scope of the  independent  annual  audit  and the  independent
auditors' letter to management  concerning the effectiveness of Orion's internal
financial and  accounting  controls.  From the time Orion became  subject to the
Exchange Act through December 31, 1995 (the "1995 Public Company  Period"),  the
Audit Committee held one meeting.

   The Compensation Committee is composed of Messrs. Brekka (chairman),  French,
Saeman  and  Van  Degna.   The  Compensation   Committee   considers  and  makes
recommendations to Orion's Board of Directors with respect to programs for human
resource  development  and  management  organization  and  succession,  approves
changes in senior executive compensation, considers and makes recommendations to
Orion's Board of Directors with respect to compensation matters and policies and
employee  benefit and incentive plans and exercises  authority  granted to it to
administer such plans and  administers  Orion's stock option and grants of stock

engaged  as  chairman  of  the  Executive   Committee  in  connection  with  the
Transactions.

   The Finance Committee is composed of Messrs. Brekka, Hauser, Kahn (chairman),
Puente,   Rice  and  Saeman.   The  Finance   Committee   considers   and  makes
recommendations  to the Board of Directors with respect to the financial affairs
of Orion,  including  matters  relating to capital  structure and  requirements,
financial  performance,   dividend  policy,  capital  and  expense  budgets  and
significant  capital  commitments.  During the 1995 Public Company  Period,  the
Finance Committee held ten meetings. Four of the members attended at least eight
of these meetings; Messrs. Rice and Brekka attended fewer than that number.

<PAGE>


   The  Nominating  Committee is composed of Messrs.  French,  Puente and Saeman
(chairman).  The  Nominating  Committee  recommends  to the  Board of  Directors
qualified   candidates   for  election  as  directors  of  Orion  and  considers
candidates, if any, recommended by stockholders.  During the 1995 Public Company
Period, the Nominating Committee held one meeting. Each member of the Nominating
Committee attended this meeting.

LIMITS ON LIABILITY; INDEMNIFICATION

   Orion's Certificate of Incorporation provides that Orion's directors will not
be liable for monetary  damages for breach of the  directors'  fiduciary duty of
care to  Orion  and its  stockholders.  This  provision  in the  Certificate  of
Incorporation   does  not  eliminate  the  duty  of  care,  and  in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary  relief would remain  available  under  Delaware law. In accordance
with the  requirements  of Delaware law,  Orion's  directors  remain  subject to
liability  for  monetary  damages (i) for any breach of their duty of loyalty to
Orion  or its  stockholders,  (ii) for acts or  omissions  not in good  faith or
involving  intentional  misconduct  or knowing  violation  of law,  (iii)  under
Section 174 of the Delaware General  Corporation Law for approval of an unlawful
dividend  or  an  unlawful  stock  purchase  or  redemption  and  (iv)  for  any
transaction from which the director derived an improper personal  benefit.  This
provision  also does not affect a  director's  responsibilities  under any other
laws,  such as the  federal  securities  laws or state or federal  environmental
laws.

   Orion's  Certificate of Incorporation also provides that, except as expressly
prohibited  by law,  Orion shall  indemnify any person who was or is a party (or
threatened to be made a party) to any threatened,  pending or completed  action,
suit or  proceeding  by reason of the fact that such person is or was a director
or officer of Orion (or is or was  serving at the request of Orion as a director
or officer of another enterprise), against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding if such person
acted in good faith and a manner such person reasonably believed to be in or not
opposed to the best interests of Orion, and, with respect to any criminal action
or  proceeding,  had no  reasonable  cause to  believe  his or her  conduct  was
unlawful.  Such indemnification shall not be made in respect of any claim, issue
or matter as to which such person shall have been adjudged to be liable to Orion
unless (and only to the extent that) the Delaware Court of Chancery or the court
in which such action or suit was  brought  determines  that,  in view of all the
circumstances  of the case,  such  person is fairly and  reasonably  entitled to
indemnity.

COMPENSATION OF DIRECTORS

   Prior to January 1996 (Orion having become a publicly  traded  company during
1995),  directors  did not  receive  compensation  for  serving  on the Board of
Directors or its  committees  but were  reimbursed  for their  expenses for each
Board of Directors or committee  meeting  attended.  Commencing in January 1996,
directors  receive  annual  compensation  of  $4,000,  $1,500  for each Board of
Directors  meeting  attended,  $750 for each committee  meeting attended and per
annum grants of stock  options to purchase  10,000  shares of Common Stock under
the 1996 Non-Employee Director Stock Option Plan. An initial grant of options to
purchase  10,000  shares  of  Common  Stock  under  that  plan  was made to each
non-employee  director in January 1996. In addition, an initial grant of options
to  purchase  30,000  shares of Common  Stock  under that plan was made to Barry
Horowitz, a director, upon his election in March 1996. The option exercise price
of the options  granted to each  non-employee  director in January  1996 and Mr.
Horowitz in March 1996 was equal to the fair market value of Common Stock on the
respective dates the options were granted.

EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

   Orion has not entered into any  employment  agreements or any  termination of
employment or change in control  arrangements  with any of its officers,  except
for certain change in control  vesting  provisions in the 1987 Stock Option Plan
described below.

   In his capacity as a consultant to the Company, John G. Puente, a director of
the Company and Chairman of the Executive Committee, is compensated at a rate of
$25,000 per month and has been granted  non-incentive  stock options to purchase
up to an  aggregate of 100,000  shares of Common  Stock at an exercise  price of
$9.83 per share.  Of the options  granted to Mr. Puente,  50% are vested and 50%
will vest upon the successful  completion during Mr. Puente's tenure as Chairman
of the Executive Committee or within six months thereafter, of the Offering. All
options granted to Mr. Puente will vest  immediately  upon the sale or merger of
the Company during Mr. Puente's tenure as Chairman of the Executive Committee or
within six months thereafter.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

   Mr.  Bauer,  the  President  and Chief  Executive  Officer of Orion,  and Mr.
Puente,  then  Chairman  of Orion,  served  on the  Compensation  Committee  and
therefore  participated in making  recommendations  to the Board of Directors on
officer compensation matters until June 28, 1995.

incentive  stock  options  intended to qualify as such under  Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"),  and nonstatutory  stock
options.  The 1987 Employee Stock Option Plan will terminate in May 1997, unless
sooner terminated by the Board of Directors.

   The 1987 Employee  Stock Option Plan is  administered  by the Board,  but the
Board has  delegated  administration  to the  Compensation  Committee,  which is
comprised of  disinterested  directors.  Subject to the limitations set forth in
the  1987  Employee  Stock  Option  Plan,  the  Compensation  Committee  has the
authority to select the persons to whom grants are to be made,  to designate the
number of shares to be covered  by each  option and  whether  such  option is an
incentive  stock option or a  nonstatutory  stock option,  to establish  vesting
schedules,  to  specify  the  type of  consideration  to be paid to  Orion  upon
exercise  and,  subject to certain  restrictions,  to specify other terms of the
options.  The maximum  term of options  granted  under the 1987  Employee  Stock
Option Plan is ten years.  The  aggregate  fair  market  value of the stock with
respect to which incentive  stock options are first  exercisable in any calendar
year may not exceed  $100,000 per  individual.  Options  granted  under the 1987
Employee  Stock Option Plan  generally  are  non-transferable  and expire either
upon, or 30 days after, the termination of an optionee's employment relationship
with Orion.  In general,  if an optionee dies or is permanently  disabled during
his or her  employment  by or  service  to Orion,  such  person's  option may be
exercised up to one year following such death or disability.

   Options  granted under the 1987  Employee  Stock Option Plan to the executive
officers  will  immediately  vest in the  event  the  optionee's  employment  is
terminated  within two years after a "Change in Control" by Orion other than for
"Cause" or by the  optionee  for "Good  Reason" (as such terms are defined in an
applicable  resolution of the Board of  Directors).  "Cause" for  termination of
employment is narrowly  defined,  including  only such matters as fraud, a crime
involving moral  turpitude,  compromising  trade secrets,  willfully  failing to
perform  material  assigned  duties or gross or willful  misconduct  that causes
substantial  harm to Orion.  "Good Reason"  means a reduction in the  optionee's
base  salary,  except  for a  reduction  of up to  10%  due  to a  reduction  in
compensation  generally applicable to executive officers of Orion, a substantial
reduction  in  responsibilities  or required  relocation.  A "Change in Control"
occurs  when any person or entity  becomes  the  beneficial  owner,  directly or
indirectly,  of securities representing 51% or more of the combined voting power
of  Orion's  then  outstanding   securities  (excluding  for  purposes  of  such
computation all securities of Orion  beneficially owned by such person or entity
as of March 15, 1995).

   The exercise  price of incentive  stock  options must equal at least the fair
market  value of the Common Stock on the date of grant.  The  exercise  price of
nonstatutory  stock options may be less than the fair market value of the Common
Stock on the date of  grant.  The  exercise  price of  incentive  stock  options
granted to any person who at the time of grant owns stock  possessing  more than
10% of the total combined  voting power of all classes of stock must be at least
110% of the fair market value of such stock on the date of grant and the term of
these options cannot exceed five years.

   As of  September  30,  1996,  Orion had  options  outstanding  under the 1987
Employee Stock Option Plan to purchase an aggregate of 891,776 shares held by 86
persons at a weighted  average  exercise price of $9.77 per share.  The exercise
price of all options  granted under the 1987 Employee Stock Option Plan has been
at least equal to the fair market  value of the Common  Stock on the date of the
grant as determined in good faith by the Board of Directors. As of September 30,
1996, options to purchase 129,755 shares of Common Stock granted pursuant to the
Plan had been exercised.  There are 449,057 shares of Common Stock available for
future grants under the 1987 Employee Stock Option Plan.

   The 1987 Employee  Stock Option Plan may be amended by the Board,  subject to
stockholder  approval if such approval is then required by applicable  law or in
order for the 1987  Employee  Stock  Option  Plan to  continue  to  satisfy  the
requirements of Rule 16b-3 under the Exchange Act.

   Non-Employee  Director Stock Option Plan. In January 1996,  Orion adopted its
Non-Employee  Director  Stock Option Plan  ("Non-Employee  Director Stock Option
Plan")  and up to  380,000  shares of Common  Stock are  reserved  for  issuance
thereunder.  The stock options  granted under the  Non-Employee  Director  Stock
Option Plan are non-incentive options.

   Under  the  terms  of the  Non-Employee  Director  Stock  Option  Plan,  each
Non-Employee  Director (as defined)  generally will receive or have vest options
to purchase  10,000 shares of Common Stock for each year that such  Non-Employee
Director serves as a director of Orion. Each current Non-Employee

                                       85

<PAGE>


Director has a vested option to purchase  10,000 shares of Common Stock,  and an
unvested option to purchase 10,000 shares of Common Stock which will vest at the
next annual  meeting of  stockholders  (expected to be held in May 1997) if such
director  remains in office until such date.  In  addition,  Mr.  Horowitz,  who
became a director on May 20, 1996, has an additional  option to purchase  10,000
shares  which  will  vest  if  he  remains  in  office  until  the  1998  annual
stockholders  meeting.  Each  current  Non-Employee  Director  will be  annually
granted an additional option to purchase 10,000 shares of Common Stock each year
after the annual  meeting of  stockholders  if he or she is then a  Non-Employee
Director.

   Each new Non-Employee  Director whose  commencement of service is after March
20, 1996 will be granted an initial  option to purchase  the number of shares of
Common Stock equal to (i) the number of complete  and partial  years in the term
to which such Non-Employee Director was elected or appointed, multiplied by (ii)
10,000.  Each Non-Employee  Director also will be annually granted an additional
option to purchase 10,000 shares of Common Stock as of each of (i) the day after
the Non-Employee Director's first re-election to the Board of Directors and (ii)
each year  after  the  annual  meeting  of  stockholders  if he or she is then a
Non-Employee Director.

   Each option will be  exercisable  from and after the day of the first  annual
meeting of  stockholders  after grant of the  option.  In the case of an initial
option to purchase of more than 10,000 shares, the option will be exercisable to
the extent of 10,000  shares from and after the day of the first annual  meeting
of stockholders  after grant of the option,  in respect of an additional  10,000
shares from and after the day of the second annual meeting of stockholders after
grant of the  option,  and (if the  option is to  purchase  of more than  20,000
shares), in respect of an additional 10,000 shares from and after the day of the
third  annual  meeting  of  stockholders  after  grant of the  option.  Upon the
termination  of service  of a  Non-Employee  Director  in all  capacities  as an
employee and/or director of Orion and all of its affiliated companies other than
by reason of the death or permanent and total disability,  any option granted to
such Non-Employee  Director  pursuant to the Non-Employee  Director Stock Option
Plan  shall  terminate  to  the  extent  it is  not  then  exercisable.  If  the
termination  of  service  is by  reason  of the  death or  permanent  and  total
disability of a  Non-Employee  Director,  the options held by such  Non-Employee
Director  shall be  exercisable in respect of all shares subject to such options
for a period of one year from the date of such  termination  of service or until
expiration of the option, if earlier.

   The option exercise price under the  Non-Employee  Director Stock Option Plan
is equal to 100% of the fair market value of Common Stock on the date the option
is granted.  Options granted under the  Non-Employee  Director Stock Option Plan
expire if not exercised within five years from the date of grant.


   Payment for shares  purchased  under the  Non-Employee  Director Stock Option
Plan may be made either in cash or cash  equivalents,  in shares of Common Stock
with a fair market value equal to the option price, or a combination of cash and
shares of Common Stock. The Non-Employee  Director Stock Option Plan also allows
for "cashless  exercise," in which a licensed broker tenders to Orion cash equal
to the  exercise  price (plus taxes  required to be  withheld) at the time Orion
issues the stock certificates.

   The Non-Employee  Director Stock Option Plan will terminate  automatically on
March 20, 2006,  unless  previously  terminated.  No termination,  suspension or
amendment  of the  Non-Employee  Director  Stock  Option  Plan may,  without the
consent of the optionee to whom an option has been granted, adversely affect the
rights of the holder of the option.

   Other Stock  Options.  From time to time, the Board of Directors of Orion may
grant  options to purchase  shares of Common Stock  outside of the 1987 Employee
Stock Option Plan and  Non-Employee  Director  Stock Option Plan. As of November
30, 1996,  options to purchase an  aggregate  of 123,987  shares of Common Stock
were  outstanding  outside of such plans at an average  exercise price of $8.30.
During 1995, 6,463 options granted outside of such plans were exercised.

OTHER EMPLOYEE BENEFIT PLANS

   1997 Employee Stock Purchase Plan. In September 1996,  Orion adopted its 1997
Employee  Stock  Purchase  Plan (the  "Stock  Purchase  Plan").  Under the Stock
Purchase  Plan,  eligible  employees  may purchase up to an aggregate of 500,000
shares of Common Stock through payroll  deductions.  Eligible  employees include
all employees except those who have been employed by Orion for less than three

                                       86

<PAGE>



months,  those who work less than five months per calendar  year or less than 20
hours per week, and those who would own 5% or more of the total combined  voting
power of all classes of Orion's  capital stock upon their  participation  in the
Stock  Purchase  Plan.  The Stock  Purchase Plan will terminate at the sooner of
September  2006 or such time as all shares of Common Stock  available  under the
Stock Purchase Plan have been issued.

   The Stock  Purchase  Plan is  administered  by the  Board,  but the Board has
delegated  administration  to its Human  Resources and  Compensation  Committee.
Employees may commence  participation in the Stock Purchase Plan or change their
payroll  deduction  percentages  effective  at the  beginning  of each  calendar
quarter. On the last day of each quarter, all funds accumulated in an employee's
account are used to purchase shares of Common Stock at a purchase price equal to
the lesser of 85% of the fair market value of such Common Stock (i) on the first
trading day of the quarter or (ii) on the last trading day of the  quarter,  but
in no event shall the  per-share  price be less than the par value of the Common
Stock ($.01). No employee may purchase in any one calendar year shares of Common
Stock having an aggregate  fair market value in excess of $25,000.  Common Stock
purchased   under  the  Stock   Purchase  Plan  is  entitled  to  full  dividend
participation.

   An employee's  participation  in the Stock  Purchase  Plan  terminates in the
event the  employee  voluntarily  terminates  such  participation,  ceases to be
employed by Orion or ceases to be eligible to  participate in the Stock Purchase
Plan, or in the event the Board elects to terminate the Stock  Purchase Plan. An
employee who retires,  is laid off, takes a leave of absence,  dies or suffers a
disability may directly or, in the case of death,  through the employee's estate
withdraw any payroll  deductions  remaining in the employee's  account,  receive
that  number of shares of Common  Stock which may be  purchased  with the amount
then credited to the employees account, or make up any deficiency resulting from
missed payroll  deductions  through an immediate cash payment.  Participation in
the Stock  Purchase  Plan may resume at the beginning of the next quarter if the
employee again becomes eligible to participate.

   The Stock  Purchase  Plan is not subject to the  Employee  Retirement  Income
Security Act of 1974, as amended  ("ERISA"),  nor is it qualified  under Section
401(a) of the Code. As of November 15, 1996, no shares of Common Stock have been
purchased or issued under the Stock Purchase Plan.

   1997 401(k) Profit  Sharing Plan. In September  1996,  Orion adopted its 1997
401(k) Profit Sharing Plan (the "401(k) Plan").  Under the 401(k) Plan, eligible
employees may elect to have a portion of their pay deducted for  investment in a
variety of mutual  funds that invest in equity and debt  securities  and a money
market  account.  In  addition,  Orion  may  in  its  discretion  make  matching
contributions  in the form of cash or in the equivalent  amount of Common Stock,
and may make profit sharing contributions.  Up to 100,000 shares of Common Stock
are issuable as matching  contributions  under the 401(k) Plan.  The 401(k) Plan
will  continue  indefinitely  unless  terminated  by  Orion  at any  time in its
discretion.  Orion may also suspend matching and profit sharing contributions at
any time in its sole discretion.

   The 401(k) Plan is administered under a written trust agreement between Orion
and certain  trustees (the "401(k)  Trustees").  The 401(k) Trustees oversee the
investment of employee contributions, and Orion administers all other matters in
connection with the day-to-day  operation of the 401(k) Plan. Eligible employees
may elect to deduct up to $9,500 of their  compensation  on a pre-tax basis in a
given calendar year. The 401(k)  Trustees have  discretion to select among these
investment  media,  or employees may direct the 401(k)  Trustees to invest their
payroll deductions in accordance with specific instructions.  At its discretion,
Orion  may  match  all or part of  employee  payroll  deductions  in cash or the
equivalent  amount of Common Stock. In addition,  Orion may also make additional
profit  sharing  contributions  in its  discretion  by  distributing  a  certain
percentage  of its  profits  to  employees  pro rata  based  on the  ratio of an
employee's   compensation   to  the  total   compensation  of  all  401(k)  Plan
participants.  Orion is responsible for directing the investment of any matching
or profit sharing contributions it makes to employee accounts.

   An employee's  payroll  deductions (and any rollover  contributions  into the
401(k)  Plan) and earnings  thereon are always 100% vested and  non-forfeitable.
Matching and profit sharing contributions become 100% vested and non-forfeitable
for any employee who attains age 65, dies, or becomes disabled while working for
Orion. An employee whose employment terminates for any other reason will be

                                       87

<PAGE>



0% vested in any matching and profit sharing contribution which the employee has
received if the  employee has less than two years of service with Orion and 100%
vested in such matching and profit sharing contributions if the employee has two
or more years of service.  The 401(k) Plan allows  employees to begin  receiving
benefits  upon  age 65 or  upon  becoming  disabled  while  employed  by  Orion.
Employees may also  withdraw from their account in the event of certain  defined
hardships, and may borrow between $1,000 and the lesser of $50,000 or 50% of the
vested  amounts  in  their  accounts  at the  401(k)  Trustee's  discretion.  An
employee's  participation  in the  401(k)  Plan will  terminate  in the event of
voluntary termination by the employee,  termination of the employee's employment
or eligibility, or Orion's election to terminate the 401(k) Plan.

   The  401(k)  Plan is  qualified  under  Section  401(a)  of the Code and as a
qualified cash or deferred compensation  arrangement under Section 401(k) of the
Code.  The  401(k)  Plan  is  also  subject  to  certain  provisions  of  ERISA,
principally  Title I, relating to protection of employee benefit rights,  and to
the  provisions  of the Code relating to  retirement  plans.  As of November 15,
1996,  no  shares of  Common  Stock or other  cash  matching  or profit  sharing
contributions have been distributed under the 401(k) Plan.

                              CERTAIN TRANSACTIONS

   The following is a summary of certain  transactions  among Orion,  directors,
officers and certain stockholders of Orion, and related persons.  Orion believes
that each of such  transactions  was on terms no less  favorable  to Orion  than
reasonably   could  have  been  obtained  in  arm's-length   transactions   with
independent  third  parties.  Orion  has a policy  requiring  that any  material
transactions  between Orion and persons or entities  affiliated  with  officers,
directors or principal  stockholders  of Orion be on terms no less  favorable to
Orion than  reasonably  could be  obtained  in  arm's-length  transactions  with
independent third parties. Orion's policy is to conduct an appropriate review of
all related party  transactions  and to have the Audit Committee or a comparable
body review potential conflict of interest situations.

   Orion is a party to numerous  agreements  with one or more Limited  Partners,
most of which were  entered into in December  1991,  including  the  partnership
agreement of Orion Atlantic,  firm and contingent capacity leases (most of which
will be  terminated  in  connection  with the  Exchange),  the Orion 1 Satellite
Contract, the Orion 2 Satellite Contract, agreements with STET or its affiliates
concerning the TT&C facility,  representative agent agreements and agreements to
make  loans  or  advances  to Orion  (which  will be  terminated  as part of the
Exchange). See "The Merger and the Exchange."

   Orion entered into the Orion 1 Satellite Contract with British Aerospace,  an
affiliate of a principal  stockholder of Orion and of which Mr. Rice, a director
of  Orion,  is a Group  Treasurer.  Under  the  terms of the  Orion 1  Satellite
Contract,  Orion has paid an aggregate of $43.4 million in 1991,  $72 million in
1992 (plus a $5 million  payment upon  termination for convenience by Orion of a
second  satellite),  $26 million in 1993, $89.8 million in 1994 and $0.3 million
in 1995. As of September 30, 1996, Orion Atlantic had obligations of $15 million
to Matra  Marconi  Space with  respect to incentive  payments  under the Orion 1
Satellite  Contract,  of which $13 million will be paid on the Closing  Date. Of
this amount,  $10 million will be re-invested in Orion by Matra Marconi Space in
the Matra Marconi  Investment.  See "Description of Certain  Indebtedness."  The
balance  of  the  outstanding   obligations  are  payable  18  months  following
commencement  of  construction  under  the  Orion  2  Satellite  Contract,   and
subsequent  payments  of up to $29.4  million  may  become  payable  thereafter,
depending on satellite performance. See "Management's Discussion and Analysis of
Financial   Condition   and  Results  of  Operation  --  Liquidity  and  Capital
Resources."

   Orion has engaged certain Limited Partners as representative agents for sales
and ground  operations.  A joint venture between two Limited Partners  (Kingston
Communications   and   British   Aerospace)   serves  as  a  ground   operations
representative  in the United  Kingdom,  and the  affiliate  of another  Limited
Partner (Matra Hachette) serves as a ground operations representative in France.
Orion  paid these  Limited  Partners  an  aggregate  of $1.6  million in 1996 as
commissions and other fees (including for ground  operations and, in the case of
the Kingston Communications/British Aerospace joint venture, satellite capacity,
equipment  leasing and other  charges),  and paid these  Limited  Partners  $1.9
million in 1995 and $1.9 million in 1994 for these  services.  See  "Business --
Sales and Marketing" and " -- Network Operations; Local Ground Operators."

   In December  1991,  Orion issued 259,515 shares of Common Stock at a value of
$11.56 per share to British  Aerospace Space Systems,  Inc. in  consideration of
British   Aerospace  Space  Systems,   Inc.'s  agreement  to  guarantee  Orion's
obligations  under a $10  million  letter  of  credit  (see  Note 4 of  Notes to
Consolidated Financial Statements).  The shares were reconveyed to Orion and are
held in  treasury  at a value of $0.  The shares are  pledged  as  security  for
British  Aerospace  Space  Systems,  Inc.  in the event it is  required  to fund
amounts  under its  guarantee  and Orion does not provide  reimbursement.  These
arrangements will be terminated upon the closing of the Transactions.

   In December 1993, Orion issued an aggregate of 178,097 shares of Common Stock
as part of a private  placement of its Common Stock to certain of its  directors
and affiliates of those  directors at a purchase price of $10.20 per share.  The
terms of such issuance  permitted  the  purchasers to receive the benefit of any
lower price at which Common Stock subsequently was issued in a private placement
or to receive any other security subsequently issued in a private placement.  In
June  1994,  when  Orion  issued  shares  of  Common  Stock as part of a private
placement  of its Common  Stock to a limited  number of  institutions  and other
investors  (including  64,705  shares to  affiliates of directors) at a purchase
price of 

                                       89

<PAGE>


$8.50 per share,  Orion issued  100,326  additional  shares to the directors and
affiliates  of  directors  who  purchased  Common  Stock in  December  1993.  In
addition,  after Orion issued Series A Preferred  Stock (along with warrants and
options to make an additional  investment) to CIBC,  Fleet and Chisholm (each as
defined  below) in June 1994,  the  Directors  and  affiliates  of Directors who
purchased  Common Stock in December 1993 each  exercised  their right to receive
Series A Preferred  Stock (along with warrants and options to make an additional
investment)  in exchange for the Common  Stock  previously  acquired,  and Orion
issued an aggregate of  $3,000,000  of Series A Preferred  Stock to such persons
and entities.

   In April 1994,  Orion  entered  into an  agreement  with Space  Systems/Loral
("SS/L") whereby SS/L purchased  588,235 shares of Common Stock for an aggregate
purchase price of $5,000,000.

   In June  1994,  CIBC  Wood  Gundy  Ventures,  Inc.  ("CIBC"),  Fleet  Venture
Resources, Inc. ("Fleet") and Chisholm Partners, II, L.P. ("Chisholm") purchased
$11.5 million in Series A Preferred  Stock.  For a  description  of the Series A
Preferred  Stock,  see  "Description  of Capital  Stock -- Preferred  Stock." In
connection with the  transaction,  CIBC and Fleet each were granted the right to
elect one member of Orion's  Board of  Directors.  These rights  terminated as a
result of the Company's initial public offering.

   In June 1994,  CIBC, Inc. (an affiliate of CIBC) became a $25,000,000  lender
under the Orion 1 Credit Facility.

   In June 1995, CIBC,  Fleet and certain  directors and affiliates of directors
who purchased Series A Preferred Stock in June 1994 purchased approximately $4.2
million of Series B Preferred  Stock of Orion.  This purchase was pursuant to an
option  granted  in  June  1994.  The  Series  B  Preferred  Stock  has  rights,
designations  and  preferences  substantially  similar  to those of the Series A
Preferred Stock, and is subject to similar  covenants,  except that the Series B
Preferred  Stock is convertible  into Common Stock at an initial price of $10.20
per share, subject to certain  anti-dilution  adjustments.  For a description of
the Series B Preferred  Stock,  see  "Description  of Capital Stock -- Preferred
Stock."

   In November 1995, Orion Atlantic  redeemed the limited  partnership  interest
previously  held by STET for an aggregate of  approximately  $11.5  million (the
"STET  Redemption"),  consisting  of $3.5  million  in cash  and $8  million  in
promissory notes, $3.5 million (plus accrued interest of approximately $400,000)
of which  will be paid on the  Closing  Date.  As part of the  STET  Redemption,
Telecom Italia, a subsidiary of STET,  entered into a  representative  agreement
and distributor arrangement with Orion providing for sales, marketing,  customer
support and ground operations  services in Italy. Orion Atlantic funded the STET
Redemption by selling a new limited partnership interest to Orion for $8 million
(including  $3.5 million in cash and $4.5  million in  promissory  notes),  $3.5
million (plus accrued interest of approximately  $400,000) of which will be paid
on the Closing Date).  Orion  Atlantic also entered into  amendments to existing
contracts  with STET  that were  expected  to  result in a cash  savings  by the
Company of approximately $3.5 million over a ten-year period. In connection with
the STET Redemption, Orion agreed to indemnify Telecom Italia for payments which
would be made  under its firm and  contingent  capacity  agreements  with  Orion
Atlantic. Such indemnity will be discontinued on the Closing Date.

   In July 1996,  Matra Marconi Space,  the parent company of MMS Space Systems,
the prime  contractor  for Orion 1, entered into the Orion 2 Satellite  Contract
with Orion  regarding  construction  of Orion 2, which  contract  was amended in
December  1996.  Certain  terms of the Orion 2 Satellite  Contract are described
above under the  caption  "Business  --  Implementation  of the Orion  Satellite
System -- Orion 2." Matra Hachette, one of the parent companies of Matra Marconi
Space,  will be a more  than 5%  beneficial  owner of  Common  Stock  after  the
Exchange and the Merger. See "The Merger and the Exchange."

   Effective as of June 1996,  Orion and the Limited  Partners  entered into the
Exchange  Agreement.  In December  1996 and January 1997,  the Limited  Partners
agreed to extend to April 30, 1997 the  termination  date for the Exchange.  See
"The Merger and the Exchange."

   Effective as of January 13,  1997,  Orion and each of British  Aerospace  and
Matra Marconi Space  entered into the Debenture  Agreement.  The net proceeds of
the Debenture Investments, which will occur concurrently with this Offering, are
estimated to be approximately $59 million.  Such net proceeds are expected to be
used for  initial  payments  to the  manufacturers  under the Orion 2  Satellite
Contract.

                            PRINCIPAL STOCKHOLDERS

   The  following  table sets forth  certain  information  regarding  beneficial
ownership  of the  Company's  Common  Stock,  as of September  30, 1996,  and as
adjusted  to  reflect  the  beneficial  ownership  of  Common  Stock  after  the
Transactions,  assuming for this purpose that the Transactions close January 30,
1997 (if the  Transactions  close  after such date,  the Limited  Partners  will
beneficially own greater amounts of Common Stock), by (i) each stockholder known
by the  Company  to be the  beneficial  owner of more than five  percent  of the
outstanding Common Stock, (ii) each director of the Company,  (iii) each current
executive  officer  named  in the  Summary  Compensation  Table,  and  (iv)  all
directors and executive  officers as a group.  Except as indicated,  the Company
believes  that,  based on information  furnished by such owners,  the beneficial
owners of the Common Stock listed  below have sole  investment  and voting power
with  respect  to  such  shares,   subject  to  community  property  laws  where
applicable.

SECURITY

   
   The Senior Notes Indenture will provide that on the Closing Date, the Company
must  purchase  and pledge to the Senior  Notes  Trustee  for the benefit of the
Holders of the Senior  Notes the  Pledged  Securities  in such amount as will be
sufficient  upon receipt of scheduled  interest and  principal  payments of such
securities, in the opinion of a nationally recognized firm of independent public
accountants selected by the Company, to provide for payment in full of the first
six scheduled  interest payments due on the Senior Notes. The Company expects to
use approximately  $118.8 million of the net proceeds of the Offering to acquire
the Pledged Securities; however, the precise amount of securities to be acquired
will depend upon the interest rates on Government  Securities  prevailing on the
Closing  Date.  The  Pledged  Securities  will be pledged by the  Company to the
Senior Notes Trustee for the benefit of the Holders of the Senior Notes pursuant
to the  Pledge  Agreement  and will be held by the Senior  Notes  Trustee in the
Pledge  Account.  Pursuant  to the  Pledge  Agreement,  immediately  prior to an
Interest  Payment Date on the Senior Notes,  the Company may either deposit with
the Senior  Notes  Trustee  from funds  otherwise  available to the Company cash
sufficient to pay the interest  scheduled to be paid on such date or the Company
may direct the Senior Notes Trustee to release from the Pledge Account  proceeds
sufficient to pay interest  then due on the Senior Notes.  In the event that the
Company  exercises  the former  option,  the Company may  thereafter  direct the
Senior Notes  Trustee to release to the Company  proceeds or Pledged  Securities
from the Pledge Account in like amount.  A failure to pay interest on the Senior
Notes in a timely manner through the first six scheduled  interest payment dates
will constitute an immediate Event of Default under the Senior Notes  Indenture,
with no grace or cure period.     

   Interest  earned  on the  Pledged  Securities  will be  added  to the  Pledge
Account.  In the event that the funds or Pledged  Securities  held in the Pledge
Account exceed the amount sufficient,  in the opinion of a nationally recognized
firm of independent public accountants  selected by the Company,  to provide for
payment in full of the first six scheduled  interest  payments due on the Senior
Notes (or,  in the event an  interest  payment or  payments  have been made,  an
amount  sufficient  to  provide  for  payment in full of any  interest  payments
remaining, up to and including the sixth scheduled interest payment), the Senior
Notes  Trustee  will be  permitted  to release to the  Company at the  Company's
request any such excess amount.  The Senior Notes will be secured by the Pledged
Securities and in the Pledge Account and,  accordingly,  the Pledged  Securities
and the Pledge Account will also secure repayment of the principal amount of the
Senior Notes to the extent of such security.

   Under the Pledge  Agreement,  assuming  that the Company  makes the first six
scheduled  interest payments on the Senior Notes in a timely manner,  all of the
remaining  Pledged  Securities  will be  released  from the Pledge  Account  and
thereafter the Senior Notes will be unsecured.

GUARANTEES

   The  Company's  obligations  under the  Notes  are fully and  unconditionally
guaranteed  on a  senior  basis  by  the  Guarantors,  provided  that  the  Note
Guarantees shall not be enforceable against any Guarantor in an amount in excess
of the net worth of such  Guarantor at the time that  determination  of such net
worth is, under  applicable  law,  relevant to the  enforceability  of such Note
Guarantees. Such net worth shall include any claim of such Guarantor against the
Company  for  reimbursement  and any  claim  against  any  other  Guarantor  for
contribution.

RANKING

   The  indebtedness  evidenced by the Notes and the Note  Guarantees  will rank
pari  passu in right of payment  with all  existing  and  future  unsubordinated
indebtedness  of the Company  and the  Guarantors,  respectively,  and senior in
right of payment to all existing  and future  subordinated  indebtedness  of the
Company and the Guarantors,  respectively.  After giving pro forma effect to the
Transactions,  as of  September  30,  1996,  the  Company  would have had (on an
unconsolidated  basis)  $60.0  million of  indebtedness  (other  than the Notes)
outstanding,  all of which would have been  subordinated  indebtedness,  and the
Guarantors,  collectively,  would have had $24.9 million of indebtedness  (other
than the Note Guar-

                                       98

<PAGE>


antees)  outstanding,  all of which would have been unsubordinated  indebtedness
($7.2  million of which  would  have been  secured  by the  Company's  satellite
control facility) and no subordinated indebtedness.  The Note Guarantees will be
effectively  subordinated to all such secured  indebtedness to the extent of the
collateral therefor.

a  "Semi-Annual  Accrual  Date"),  the Accreted  Value will equal the amount set
forth below for such Semi-Annual Accrual Date:

        (ii) if the Specified Date occurs before the first  Semi-Annual  Accrual
   Date,  the Accreted  Vale will equal the sum of (a) the original  issue price
   and (b) an amount  equal to the  product  of (1) the  Accreted  Value for the
   first  Semi-Annual  Accrual Date less the original issue price  multiplied by
   (2) a fraction,  the  numerator of which is the number of days from the issue
   date of the Senior Discount Notes to the Specified Date, using a 360-day year
   of twelve 30-day months,  and the  denominator of which is the number of days
   elapsed  from the  issue  date of the  Senior  Discount  Notes  to the  first
   Semi-Annual Accrual Date, using a 360-day year of twelve 30-day months;

        (iii) if the  Specified  Date  occurs  between two  Semi-Annual  Accrual
   Dates,  the Accreted  Value will equal the sum of (a) the Accreted  Value for
   the Semi-Annual  Accrual Date  immediately  preceding such Specified Date and
   (b) an  amount  equal  to the  product  of (1)  the  Accreted  Value  for the
   immediately  following  Semi-Annual  Accrual Date less the Accreted Value for

   fraction,  the numerator of which is the number of days from the  immediately
   preceding  Semi-Annual  Accrual Date to the Specified  Date,  using a 360-day
   year of twelve 30-day months, and the denominator of which is 180; or

        (iv) if the  Specified  Date occurs after the last  Semi-Annual  Accrual
   Date, the Accreted Value will equal $1,000.

   "Acquired  Indebtedness"  means Indebtedness of a Person existing at the time
such Person  becomes a Restricted  Subsidiary or assumed in  connection  with an
Asset  Acquisition  by a Restricted  Subsidiary  and not Incurred in  connection

upon  consummation of the transactions by which such Person becomes a Restricted
Subsidiary or such Asset Acquisition shall not be Acquired Indebtedness.

exchange for, or the net proceeds of which are used to refinance or refund, then
outstanding Indebtedness,  other than Indebtedness Incurred under clause (i)(B),

or  instrument  pursuant  to which  such new  Indebtedness  is issued or remains
outstanding,  is expressly made  subordinate in right of payment to the Notes or
the  Note  Guarantees  at  least  to the  extent  that  the  Indebtedness  to be
refinanced is subordinated to the Notes or the Note Guarantees,  as the case may
be, and (C) such new  Indebtedness,  determined  as of the date of Incurrence of
such new  Indebtedness,  does not  mature  prior to the Stated  Maturity  of the

the extent such Net Cash  Proceeds  are used to Incur  Indebtedness  pursuant to
clause (viii) of the second  paragraph  under the  "Limitation on  Indebtedness"
covenant  described  above,  plus (3) an amount  equal to the net  reduction  in
Investments  (other than  reductions  in  Permitted  Investments)  in any Person
resulting from payments of interest on  Indebtedness,  dividends,  repayments of
loans or advances,  or other transfers of assets, in each case to the Company or
any  Restricted  Subsidiary  or from the Net Cash  Proceeds from the sale of any
such  Investment  (except,  in each  case,  to the  extent  any such  payment or
proceeds are included in the calculation of Adjusted  Consolidated  Net Income),
or from redesignations of Unrestricted  Subsidiaries as Restricted  Subsidiaries
(valued in each case as provided in the  definition  of  "Investments"),  not to
exceed,  in each case, the amount of Investments  previously made by the Company
or any Restricted Subsidiary in such Person or Unrestricted Subsidiary.

   The foregoing  provision  shall not be violated by reason of: (i) the payment
of any dividend within 60 days after the date of declaration thereof if, at said
date of  declaration,  such payment would comply with the  foregoing  paragraph;
(ii) the redemption,  repurchase,  defeasance or other acquisition or retirement
for value of Indebtedness  that is subordinated in right of payment to the Notes

paragraph of part (a) of the "Limitation on  Indebtedness"  covenant;  (iii) the
repurchase,  redemption or other acquisition of Capital Stock of the Company (or
options,  warrants or other rights to acquire  such  Capital  Stock) in exchange
for, or out of the proceeds of a substantially concurrent offering of, shares of

any principal payment or the repurchase,  redemption,  retirement, defeasance or
other acquisition for value of Indebtedness of the Company which is subordinated
in right of payment to the Notes in exchange  for, or out of the  proceeds of, a
substantially concurrent offering of, shares of the Capital Stock of the Company
(other than Disqualified  Stock);  (v) payments or distributions,  to dissenting
stockholders  pursuant to applicable  law,  pursuant to or in connection  with a
consolidation, merger or transfer of assets that complies with the provisions of

repurchase,  redemption or other  acquisition of outstanding  shares of Series A
Preferred  Stock or Series B  Preferred  Stock,  which  shares  either  (A) were

<PAGE>

Series A Preferred  Stock which were issued  pursuant to the exercise of options
that were  outstanding  on the  Closing  Date,  in  exchange  for, or out of the
proceeds  of, an  issuance of  Indebtedness  Incurred  under  clause (ix) of the
second  paragraph of part (a) of the "Limitation on Indebtedness"  covenant;  or
(vii)  Investments to the extent the amount invested consists solely of Net Cash
Proceeds  received  by the  Company or any  Guarantor,  within six months of the
making  of  such  Investment,  from  the  issuance  and  sale  permitted  by the
Indentures of its Capital Stock (other than Disqualified  Stock) to a Person who
is not a Subsidiary of the Company or any Guarantor; (viii) Investments, the sum
of which  does not  exceed $5  million  at any one time  outstanding;  (ix) cash
payments, not to exceed $3 million, in lieu of the issuance of fractional shares
of Capital  Stock of the Company  upon the exercise of the Warrants or any other
warrants to buy, or upon the  conversion  of any  securities  convertible  into,
Capital  Stock of the  Company;  and (x) a one-time  cash  payment of up to $3.0
million to the  holders of the Junior  Subordinated  Convertible  Debentures  in
connection  with  the  disposition  of  the  Junior   Subordinated   Convertible
Debentures in an underwritten  public  offering  pursuant to Section 11.4 of the
Debenture Purchase  Agreement;  provided that, except in the case of clauses (i)
and (iii),  no Default or Event of Default shall have occurred and be continuing
or occur as a consequence of the actions or payments set forth therein.

   Each Restricted Payment permitted pursuant to the preceding  paragraph (other
than the Restricted  Payment  referred to in clause (ii) thereof and an exchange
of Capital Stock for Capital Stock or  Indebtedness  referred to in clause (iii)
or (iv)  thereof) and the Net Cash  Proceeds  from any issuance of Capital Stock
referred to in clauses (iii) and (iv) shall be included in  calculating  whether
the  conditions  of clause (C) of the first  paragraph  of this  "Limitation  on
Restricted  Payments"  covenant  have been met with  respect  to any  subsequent
Restricted  Payments.  In the event the proceeds of an issuance of Capital Stock
of the Company are used for the redemption,  repurchase or other  acquisition of
the Notes, or Indebtedness  that is pari passu with the Notes, then the Net Cash
Proceeds of such issuance shall be included in clause (C) of the first paragraph
of this  "Limitation  on Restricted  Payments"  covenant only to the extent such
proceeds are not,  within six months,  used for such  redemption,  repurchase or
other acquisition of Indebtedness.

   Any  Restricted  Payments  made  other  than in cash  shall be valued at fair
market value.  The amount of any Investment  "outstanding"  at any time shall be
deemed to be equal to the amount of such  Investment on the date made,  less the
return of capital to the Company and its Restricted Subsidiaries with respect to
such Investment (up to the amount of such Investment on the date made).

LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES

   The Company  will not sell,  and will not permit any  Restricted  Subsidiary,
directly  or  indirectly,  to issue or sell,  any shares of  Capital  Stock of a
Restricted Subsidiary  (including options,  warrants or other rights to purchase
shares of such  Capital  Stock)  except  (i) to the  Company  or a Wholly  Owned
Restricted  Subsidiary;  (ii) issuances of director's qualifying shares or sales
to  foreign  nationals  of  shares  of  Capital  Stock  of  foreign   Restricted
Subsidiaries,  to the extent required by applicable  law; (iii) if,  immediately
after giving effect to such issuance or sale, such Restricted  Subsidiary  would
no longer  constitute a Restricted  Subsidiary,  provided any Investment in such
Person  remaining  after giving  effect to such issuance or sale would have been
permitted to be made under the "Limitation on Restricted Payments" covenant,  if
made on the date of such issuance or sale; and (iv) issuances or sales of Common
Stock of any Restricted Subsidiary,  the Net Cash Proceeds of which are promptly
applied  pursuant  to  clause  (A) or (B) of the  "Limitation  on  Asset  Sales"
covenant described below; provided that at no time may a Restricted  Subsidiary,
the Common Stock of which has been issued or sold  pursuant to this clause (iv),
be the owner of a satellite.

ISSUANCES OF GUARANTEES BY NEW RESTRICTED SUBSIDIARIES

   The Company will provide to the Trustees, on the date that any Person becomes
a Restricted  Subsidiary,  a supplemental  indenture to each of the  Indentures,
executed  by  such  new  Restricted   Subsidiary,   providing  for  a  full  and
unconditional  guarantee on a senior basis by such new Restricted  Subsidiary of
the Company's  obligations under the Notes and the Indentures to the same extent
as that

                                       113

<PAGE>

set forth in the Senior Notes Indenture and the Senior Discount Notes Indenture,
as the case may be; provided that, in the case of any new Restricted  Subsidiary
that becomes a Restricted  Subsidiary  through the  acquisition of a majority of
its voting Capital Stock by the Company or any other Restricted Subsidiary, such
guarantee may be  subordinated to the extent required by the obligations of such
new Restricted Subsidiary existing on the date of such acquisition that were not
incurred in contemplation of such acquisition.

LIMITATION ON TRANSACTIONS WITH SHAREHOLDERS AND AFFILIATES

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the  rendering  of any  service)  with any holder (or any  Affiliate  of such
holder) of 5% or more of any class of Capital  Stock of the  Company or with any
Affiliate  of the  Company or any  Restricted  Subsidiary,  except upon fair and
reasonable terms no less favorable to the Company or such Restricted  Subsidiary
than could be obtained,  at the time of such transaction or, if such transaction
is  pursuant  to a  written  agreement,  at the  time  of the  execution  of the
agreement providing therefor,  in a comparable  arm's-length  transaction with a
Person that is not such a holder or an Affiliate.

   
   The  foregoing  limitation  does  not  limit,  and  shall  not  apply  to (i)
transactions  (A)  approved  by a majority of the  disinterested  members of the
Board of  Directors  or (B) for which the  Company  or a  Restricted  Subsidiary
delivers to the Trustees a written opinion of a nationally recognized investment
banking  firm  stating  that  the  transaction  is fair to the  Company  or such
Restricted  Subsidiary  from a  financial  point of view,  (ii) any  transaction
solely between the Company and any of its Wholly Owned  Restricted  Subsidiaries
or solely between  Wholly Owned  Restricted  Subsidiaries,  (iii) the payment of
reasonable  and  customary  regular fees to directors of the Company who are not
employees of the Company,  (iv) any payments or other  transactions  pursuant to
any  tax-sharing  agreement  between the Company and any other Person with which
the Company files a consolidated tax return or with which the Company is part of
a  consolidated  group  for  tax  purposes,  (v)  any  Restricted  Payments  not
prohibited  by  the  "Limitation  on  Restricted  Payments"  covenant  or  (vii)
Kingston's  and Matra's  rights to  commissions  and other  payments under sales
representation  or ground  operations  agreements;  Matra's  rights to payments,
including without  limitation  incentive  payments,  under the Orion 1 Satellite
Contract and Orion 2 Satellite  Contract;  and Kingston's rights to payments for
services under network  monitoring  contracts,  in each case as in effect on the
Closing  Date and with such  extensions,  amendments  and  renewals  that may be
entered  into on terms at least as  favorable  to the Company or its  Restricted
Subsidiaries,  as the case may be, as the terms of  agreements  in effect on the
Closing Date.  Notwithstanding  the foregoing,  any  transaction  covered by the
first  paragraph of this  "Limitation  on  Transactions  with  Shareholders  and
Affiliates"  covenant  and not  covered  by  clauses  (ii)  through  (v) of this
paragraph,  the aggregate  amount of which exceeds $5 million in value,  must be
approved or determined to be fair in the manner provided for in clause (i)(A) or
(B) above.     

LIMITATION ON LIENS

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
create,  incur,  assume  or  suffer  to exist  any Lien on any of its  assets or
properties of any character,  or any shares of Capital Stock or  Indebtedness of
any Restricted  Subsidiary,  without making  effective  provision for all of the
Notes and all other  amounts due under the  Indentures  to be  directly  secured
equally and ratably  with (or, if the  obligation  or liability to be secured by
such  Lien is  subordinated  in right of  payment  to the  Notes,  prior to) the
obligation or liability secured by such Lien.

   The foregoing  limitation does not apply to (i) Liens existing on the Closing
Date;  (ii) Liens  granted after the Closing Date on any assets or Capital Stock
of the Company or its Restricted  Subsidiaries  created in favor of the Holders;
(iii) Liens with  respect to the assets of a  Restricted  Subsidiary  granted by
such  Restricted  Subsidiary  to  the  Company  or  a  Wholly  Owned  Restricted
Subsidiary to secure  Indebtedness owing to the Company or such other Restricted
Subsidiary;  (iv) Liens  securing  Indebtedness  which is Incurred to  refinance
secured Indebtedness which is permitted to be Incurred under clause

                                       114

<PAGE>

(iii) of the second  paragraph of the  "Limitation  on  Indebtedness"  covenant;
provided that such Liens do not extend to or cover any property or assets of the
Company or any Restricted  Subsidiary other than the property or assets securing
the Indebtedness being refinanced; or (v) Permitted Liens.

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
create, incur, assume or suffer to exist any Lien on Orion 1, Orion 2 or Orion 3
that secures Indebtedness, other than pursuant to clause (xxi) of the definition
of Permitted Liens.

LIMITATION ON SALE-LEASEBACK TRANSACTIONS

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  enter into any sale-leaseback transaction involving any
of its assets or properties whether now owned or hereafter acquired, whereby the
Company or a Restricted  Subsidiary sells or transfers such assets or properties
and then or  thereafter  leases such assets or properties or any part thereof or
any other assets or properties which the Company or such Restricted  Subsidiary,
as the  case may be,  intends  to use for  substantially  the  same  purpose  or
purposes as the assets or properties sold or transferred.

   The foregoing restriction does not apply to any sale-leaseback transaction if
(i) the lease is for a period,  including  renewal  rights,  of not in excess of
three  years;  (ii) the lease  secures  or  relates  to  industrial  revenue  or
pollution control bonds; (iii) the transaction is solely between the Company and
any Wholly Owned Restricted Subsidiary or solely between Wholly Owned Restricted
Subsidiaries;  or (iv) the Company or such Restricted Subsidiary,  within twelve
months  after the sale or transfer  of any assets or  properties  is  completed,
applies  an amount  not less than the net  proceeds  received  from such sale in
accordance  with clause (A) or (B) of the first  paragraph of the "Limitation on
Asset Sales" covenant described below.

LIMITATION ON ASSET SALES

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
consummate any Asset Sale unless (i) the  consideration  received by the Company
or  such   Restricted   Subsidiary   (including   the  amount  of  any  Released
Indebtedness)  is at least equal to the fair market  value of the assets sold or
disposed of and (ii) at least 85% of the consideration  received  (excluding the
amount  of any  Released  Indebtedness)  consists  of  cash  or  Temporary  Cash
Investments.  In the event and to the extent that the Net Cash Proceeds received
by the  Company  or any of its  Restricted  Subsidiaries  from one or more Asset
Sales  occurring  on or after the Closing  Date in any period of 12  consecutive
months exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of
the date  closest  to the  commencement  of such  12-month  period  for  which a
consolidated  balance sheet of the Company and its  subsidiaries  has been filed
pursuant to the "Commission Reports and Reports to Holders" covenant),  then the
Company  shall or shall cause the relevant  Restricted  Subsidiary to (i) within
twelve  months  after  the date Net Cash  Proceeds  so  received  exceed  10% of
Adjusted  Consolidated  Net  Tangible  Assets (A) apply an amount  equal to such
excess Net Cash Proceeds to permanently repay unsubordinated Indebtedness of the
Company or any Restricted Subsidiary owing to a Person other than the Company or
any of its Restricted  Subsidiaries or (B) invest an equal amount, or the amount
not so applied  pursuant  to clause (A) (or enter  into a  definitive  agreement
committing to so invest within twelve months after the date of such  agreement),
in property or assets  (other than  current  assets) of a nature or type or that
are used in a business (or in a company  having  property and assets of a nature
or type,  or engaged in a business)  similar or related to the nature or type of
the property  and assets of, or the business of, the Company and its  Restricted
Subsidiaries  existing on the date of such  investment  and (ii) apply (no later
than the end of the  twelve-month  period referred to in clause (i)) such excess
Net Cash Proceeds (to the extent not applied pursuant to clause (i)) as provided
in the following  paragraph of this  "Limitation on Asset Sales"  covenant.  The
amount  of such  excess  Net Cash  Proceeds  required  to be  applied  (or to be
committed to be applied) during such twelve-month  period as set forth in clause
(i) of the preceding  sentence and not applied as so required by the end of such
period shall constitute "Excess Proceeds."

   If, as of the first day of any calendar month, the aggregate amount of Excess
Proceeds  not  theretofore  subject  to an Offer to  Purchase  pursuant  to this
"Limitation on Asset Sales"  covenant  totals at least $10 million,  the Company
must commence, not later than the fifteenth Business Day of such month, and

                                       115

<PAGE>

consummate  an  Offer  to  Purchase  from the  Holders  on a pro  rata  basis an
aggregate principal amount Notes equal to the Excess Proceeds on such date, at a
purchase  price equal to 101% of the  principal  amount of the Senior  Notes and
101% of the Accreted  Value of the Senior  Discount  Notes,  plus, in each case,
accrued interest (if any) to the Payment Date.

INSURANCE

   The  Indentures  will  provide  that the Company  will  maintain (a) in-orbit
insurance  with  respect  to Orion 1 in an amount at least  equal to the cost to
replace such satellite with a satellite of comparable or superior  technological
capability  (as estimated by the Board of Directors) and having at least as much
transmission capacity as such satellite,  and (b) with respect to Orion 2, Orion
3,  each  other  satellite  to be  launched  by the  Company  or any  Restricted
Subsidiary and each replacement  satellite  therefor,  (i) launch insurance with
respect  to each such  satellite  covering  the  period  from the launch of such
satellite  to 180 days  following  such launch in an amount  equal to or greater
than the sum of (A) the cost to replace such satellite  pursuant to the contract
pursuant to which a replacement  satellite will be constructed,  (B) the cost to
launch a  replacement  satellite  pursuant to the  contract  pursuant to which a
replacement  satellite will be launched and (C) the cost of launch insurance for
such  satellite or, in the event that the Company has reason to believe that the
cost of obtaining  comparable  insurance  for a replacement  satellite  would be
materially  higher,  the Company's best estimate of the cost of such  comparable
insurance  and (ii) at all times  subsequent to 180 days after the launch (if it
is a Successful Launch) of each such satellite,  in-orbit insurance in an amount
at  least  equal to the cost to  replace  such  satellite  with a  satellite  of
comparable or superior  technological  capability  (as estimated by the Board of
Directors) and having at least as much  transmission  capacity as such satellite
was designed to have. The in-orbit  insurance  required by this paragraph  shall
provide that if 50% or more of a satellite's  initial capacity is lost, the full
amount of insurance will become due and payable, and that if a satellite is able
to maintain more than 50% but less than 90% of its initial capacity,  a pro-rata
portion of such insurance will become due and payable. The insurance required by
this  paragraph  shall name the Company  and/or any  Guarantor  as the sole loss
payee or payees, as the case may be, thereof.

   In the  event  that the  Company  (or a  Guarantor)  receives  proceeds  from
insurance  relating to any  satellite,  the Company (or a  Guarantor)  may use a
portion of such  proceeds  to repay any  vendor or  third-party  purchase  money
financing  pertaining to such satellite (other than Orion 1) that is required to
be repaid by reason of the loss  giving  rise to such  insurance  proceeds.  The
Company (or a  Guarantor)  may use the  remainder  of such  proceeds to develop,
construct, launch and insure a replacement satellite (including components for a
related  ground  spare) if (i) such  replacement  satellite is of  comparable or
superior technological  capability as compared with the satellite being replaced
and has at least as much  transmission  capacity as the satellite being replaced
and (ii) the  Company  will  have  sufficient  funds to  service  the  Company's
projected  debt  service   requirements  until  the  scheduled  launch  of  such
replacement  satellite and for one year  thereafter  and to develop,  construct,
launch and insure (in the amounts  required  by the  preceding  paragraph)  such
replacement satellite,  provided that such replacement satellite is scheduled to
be launched within 15 months of the receipt of such proceeds.  Any such proceeds
not used as permitted by this  paragraph  shall be applied,  within 90 days,  to
reduce  Indebtedness of the Company or shall  constitute  "Excess  Proceeds" for
purposes of the "Limitation on Asset Sales" covenant.

   
FUNDING FOR ADDITIONAL SATELLITES

   On  the  Closing  Date  the  Company  will  segregate   $178.2  million  (the
"Segregated Proceeds") of the aggregate proceeds from the issuance of the Senior
Notes and the Senior Discount Notes. The Company and its Restricted Subsidiaries
will use the Segregated  Proceeds (and any proceeds therefrom or return thereon)
only to (i)  invest in  Temporary  Cash  Investments,  (ii) make  payments  with
respect to the  purchase,  construction,  launch,  insurance for and other costs
related to  additional  satellites  and (iii) to make  payments of principal and
interest on the Notes.     

REPURCHASE OF NOTES UPON A CHANGE OF CONTROL

   The Company must  commence,  within 30 days of the  occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding,  at
a purchase price equal to 101% of

                                       116

<PAGE>

the principal  amount of the Senior Notes and 101% of the Accreted  Value of the
Senior Discount Notes, plus accrued interest (if any) to the Payment Date.

   There  can be no  assurance  that the  Company  will  have  sufficient  funds
available  at the  time of any  Change  of  Control  to make  any  debt  payment
(including  repurchases of Notes) required by the foregoing covenant (as well as
may be contained in other  securities of the Company which might be  outstanding
at the time).  The above covenant  requiring the Company to repurchase the Notes
will,   unless  consents  are  obtained,   require  the  Company  to  repay  all
indebtedness  then  outstanding  which by its  terms  would  prohibit  such Note
repurchase, either prior to or concurrently with such Note repurchase.

COMMISSION REPORTS AND REPORTS TO HOLDERS

   Whether or not the Company is required to file reports  with the  Commission,
the  Company  shall  file  with  the  Commission  all  such  reports  and  other
information  as it would be  required  to file with the  Commission  by Sections
13(a) or 15(d)  under the  Securities  Exchange  Act of 1934 if it were  subject
thereto.  The Company  shall supply the Trustees and each Holder or shall supply
to the Trustees for forwarding to each such Holder, without cost to such Holder,
copies of such reports and other information.

EVENTS OF DEFAULT

   The  following  events  will  be  defined  as  "Events  of  Default"  in  the
Indentures:  (a) default in the payment of principal of (or premium, if any, on)
any  Senior  Note or Senior  Discount  Note,  as the case may be,  when the same
becomes due and payable at maturity, upon acceleration, redemption or otherwise;
(b) default in the  payment of  interest  on any Senior Note or Senior  Discount
Note,  as the case  may be,  when the same  becomes  due and  payable,  and such
default  continues for a period of 30 days;  provided that a failure to make any
of the first six  scheduled  interest  payments on the Senior  Notes in a timely
manner will  constitute  an Event of Default with no grace or cure  period;  (c)
default  in the  performance  or  breach  of the  provisions  of the  Indentures
applicable to mergers,  consolidations and transfers of all or substantially all
of the assets of the  Company or the failure to make or  consummate  an Offer to

Notes  upon a Change of  Control"  covenant;  (d) the  Company  defaults  in the

full or such  acceleration  has not been rescinded or annulled within 30 days of
such  acceleration  and/or (II) the  failure to make a principal  payment at the
final (but not any interim) fixed maturity and such defaulted  payment shall not
have been made,  waived or extended within 30 days of such payment default;  (f)
any final  judgment or order (not covered by insurance) for the payment of money
in excess of $10 million in the aggregate for all such final judgments or orders
against all such Persons (treating any deductibles,  self-insurance or retention
as not so covered) shall be rendered  against the Company,  any Guarantor or any
Significant  Subsidiary and shall not be paid or discharged,  and there shall be
any period of 30 consecutive days following entry of the final judgment or order
that  causes  the  aggregate  amount  for all such  final  judgments  or  orders

million during which a stay of  enforcement of such final judgment or order,  by
reason of a pending  appeal or  otherwise,  shall not be in effect;  (g) a court

   If an Event of Default  (other than an Event of Default  specified  in clause
(g) or (h)  above  that  occurs  with  respect  to the  Company)  occurs  and is
continuing under the Indentures, the relevant Trustee or the Holders of at least
25% in  aggregate  principal  amount at maturity  of the Senior  Notes or Senior
Discount Notes, as the case may be, then  outstanding,  by written notice to the
Company  (and to the Trustee if such notice is given by the  Holders),  may, and
the relevant Trustee at the request of such Holders shall, declare the principal
amount (in the case of Senior  Notes) or  Accreted  Value (in the case of Senior
Discount  Notes) of, premium,  if any, and accrued  interest on such Notes to be
immediately due and payable. Upon a declaration of acceleration,  such principal
amount or Accreted  Value of,  premium,  if any, and accrued  interest  shall be
immediately  due and  payable.  In the event of a  declaration  of  acceleration
because an Event of Default  set forth in clause (e) above has  occurred  and is
continuing,  such declaration of acceleration  shall be automatically  rescinded
and annulled if the event of default  triggering such Event of Default  pursuant
to  clause  (e)  shall  be  remedied  or cured by the  Company  or the  relevant
Guarantor  or  Significant  Subsidiary  or waived by the holders of the relevant
Indebtedness  within 60 days after the declaration of acceleration  with respect
thereto. If an Event of Default specified in clause (g) or (h) above occurs with
respect to the Company,  the principal amount or Accreted Value, as the case may
be, of,  premium,  if any,  and accrued  interest on the Notes then  outstanding
shall  ipso  facto  become  and be  immediately  due  and  payable  without  any
declaration or other act on the part of the relevant Trustee or any Holder.  The
Holders  of at  least  a  majority  in  principal  amount  at  maturity  of  the
outstanding  Notes by written notice to the Company and to the relevant Trustee,
may waive all past defaults and rescind and annul a declaration of  acceleration
and its  consequences  if (i) all  existing  Events of  Default,  other than the
nonpayment of the principal of, premium,  if any, and interest on the Notes that
have become due solely by such declaration of  acceleration,  have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. For information as to the waiver of defaults,
see "-Modification and Waiver."    

   The Holders of at least a majority in aggregate  principal amount at maturity
of the  outstanding  Senior Notes or Senior  Discount Notes, as the case may be,
may  direct the time,  method and place of  conducting  any  proceeding  for any
remedy  available  to the  relevant  Trustee  or  exercising  any trust or power
conferred on the relevant Trustee.  However,  the relevant Trustee may refuse to
follow any direction that conflicts with law or the relevant Indenture, that may
involve the relevant Trustee in personal liability, or that the relevant Trustee
determines in good faith may be unduly  prejudicial  to the rights of Holders of
Senior Notes or Senior  Discount  Notes,  as the case may be, not joining in the
giving of such  direction  and may take any other action it deems proper that is
not inconsistent with any such direction  received from Holders of such Notes. A
Holder may not pursue any remedy  with  respect to the  Indentures  or the Notes
unless: (i) the Holder gives the Trustee written notice of a continuing Event of
Default;  (ii) the  Holders  of at least 25% in  aggregate  principal  amount at
maturity of outstanding  Notes make a written request to the relevant Trustee to
pursue the  remedy;  (iii) such  Holder or Holders  offer the  relevant  Trustee
indemnity satisfactory to such Trustee against any costs, liability or expense;

                                       118

<PAGE>


(iv) the relevant  Trustee does not comply with the request within 60 days after
receipt of the  request and the offer of  indemnity;  and (v) during such 60-day
period,  the Holders of a majority in aggregate  principal amount at maturity of
the  outstanding  Senior Notes or Senior  Discount Notes, as the case may be, do
not give the relevant Trustee a direction that is inconsistent with the request.
However,  such  limitations do not apply to the right of any Holder of a Note to
receive payment of the principal of, premium,  if any, or interest on, such Note
or to bring suit for the  enforcement  of any such payment,  on or after the due
date  expressed  in the Notes,  which  right  shall not be  impaired or affected
without the consent of the Holder.

   The Indentures will require certain officers of the Company to certify, on or
before a date not more than 90 days after the end of each  fiscal  year,  that a
review has been  conducted of the  activities of the Company and its  Restricted
Subsidiaries  and the Company's  and its  Restricted  Subsidiaries'  performance
under  the  Indentures  and that  the  Company  has  fulfilled  all  obligations
thereunder,  or,  if there  has been a default  in the  fulfillment  of any such
obligation,  specifying each such default and the nature and status thereof. The
Company will also be obligated to notify the Trustees of any default or defaults
in the performance of any covenants or agreements under the Indentures.

CONSOLIDATION, MERGER AND SALE OF ASSETS

   Each of the Company and each Guarantor will not consolidate  with, merge with
or into,  or  sell,  convey,  transfer,  lease or  otherwise  dispose  of all or
substantially all of its property and assets (as an entirety or substantially an
entirety in one transaction or a series of related  transactions) to, any Person
or permit any Person to merge with or into the Company or any Guarantor  unless:
(i) the Company or any  Guarantor,  as the case may be, shall be the  continuing
Person,  or the Person (if other than the Company or  Guarantor)  formed by such
consolidation or into which the Company or any Guarantor, as the case may be, is
merged or that acquired or leased such property and assets of the Company or any
Guarantor,  as the case may be,  shall be a  corporation  organized  and validly
existing  under the laws of the United  States of  America  or any  jurisdiction
thereof and shall expressly  assume, by a supplemental  indenture,  executed and
delivered  to the  Trustees,  all  of the  obligations  of  the  Company  or any
Guarantor,  as the case may be, on all of the  Notes  and under the  Indentures;
(ii) immediately after giving effect to such transaction, no Default or Event of
Default  shall  have  occurred  and be  continuing;  (iii)  if such  transaction
involves the Company or any Significant  Subsidiary  thereof,  immediately after
giving  effect to such  transaction  on a pro forma basis,  the Company,  or any
Person  becoming the successor to the Company as obligor on the Notes shall have
a Consolidated  Net Worth equal to or greater than the Consolidated Net Worth of
the Company  immediately  prior to such  transaction;  (iv) if such  transaction
involves the Company or any Significant  Subsidiary  thereof,  immediately after
giving  effect to such  transaction  on a pro forma basis,  the Company,  or any
Person  becoming the successor  obligor of the Notes,  as the case may be, could
Incur  at  least  $1.00  of  Indebtedness  under  the  first  paragraph  of  the
"Limitation on Indebtedness" covenant;  provided that this clause (iv) shall not
apply  to a  consolidation  or  merger  with or into a Wholly  Owned  Restricted
Subsidiary with a positive net worth; provided that, in connection with any such
merger or  consolidation,  no  consideration  (other  than  Common  Stock in the
surviving  Person  or  the  Company)  shall  be  issued  or  distributed  to the
stockholders of the Company;  and (v) the Company or Guarantor,  as the case may
be, delivers to the Trustees an Officers' Certificate  (attaching the arithmetic
computations to demonstrate  compliance with clauses (iii) and (iv)) and Opinion
of Counsel, in each case stating that such consolidation, merger or transfer and
such supplemental indenture complies with this provision and that all conditions
precedent  provided for herein relating to such  transaction  have been complied
with; provided,  however,  that clauses (iii) and (iv) above do not apply if, in
the good faith  determination  of the Board of Directors  of the Company,  whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such  transaction is to change the state of  incorporation  of the Company;  and
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing  limitations.  Notwithstanding  the foregoing,  the
provisions of this paragraph shall not apply to the Merger.

DEFEASANCE

   Defeasance and  Discharge.  Each Indenture will provide that the Company will
be deemed to have paid and will be discharged  from any and all  obligations  in
respect of the Senior Notes or Senior

                                       119

<PAGE>

Discount Notes, as the case may be, on the 123rd day after the deposit  referred
to below,  and the  provisions  of the relevant  Indenture  will no longer be in
effect with respect to such Notes  (except  for,  among other  matters,  certain
obligations  to register  the  transfer  or  exchange of such Notes,  to replace
stolen,  lost or mutilated Notes, to maintain paying agencies and to hold monies
for payment in trust) if, among other things, (A) the Company has deposited with
the relevant Trustee,  in trust, money and/or U.S.  Government  Obligations that
through the payment of interest and  principal in respect  thereof in accordance
with their terms will provide money in an amount sufficient to pay the principal
of,  premium,  if any, and accrued  interest on the relevant Notes on the Stated
Maturity of such payments in accordance with the terms of the relevant Indenture
and Notes,  (B) the Company has delivered to the relevant Trustee (i) either (x)
an Opinion of Counsel to the effect that Holders will not recognize income, gain
or loss for federal income tax purposes as a result of the Company's exercise of
its option  under  this  "Defeasance"  provision  and will be subject to federal
income tax on the same  amount  and in the same  manner and at the same times as
would  have been the case if such  deposit,  defeasance  and  discharge  had not
occurred, which Opinion of Counsel must be based upon (and accompanied by a copy
of) a ruling of the Internal Revenue Service to the same effect unless there has
been a change in applicable  federal  income tax law after the Closing Date such
that a ruling is no longer  required or (y) a ruling  directed  to the  relevant
Trustee  received  from the Internal  Revenue  Service to the same effect as the
aforementioned  Opinion of Counsel  and (ii) an Opinion of Counsel to the effect
that the  creation  of the  defeasance  trust does not  violate  the  Investment
Company Act of 1940 and,  after the passage of 123 days  following  the deposit,
the trust fund will not be  subject  to the effect of Section  547 of the United
States  Bankruptcy  Code or Section 15 of the New York Debtor and Creditor  Law,
(C)  immediately  after giving  effect to such deposit on a pro forma basis,  no
Event of  Default,  or event that after the giving of notice or lapse of time or
both would become an Event of Default,  shall have occurred and be continuing on
the date of such deposit or during the period  ending on the 123rd day after the
date of such deposit, and such deposit shall not result in a breach or violation
of, or constitute a default  under,  any other  agreement or instrument to which
the Company or any of its  Subsidiaries  is a party or by which the Company,  or
any of its  Subsidiaries is bound,  and (D) if at such time the Notes are listed
on a national  securities  exchange,  the Company has  delivered to the relevant
Trustee an Opinion of Counsel to the effect  that the Notes will not be delisted
as a result of such deposit, defeasance and discharge.

   Defeasance of Certain Covenants and Certain Events of Default. Each Indenture
further will provide that the  provisions of such Indenture will no longer be in
effect with respect to clauses (iii) and (iv) under  "Consolidation,  Merger and
Sale of  Assets"  and all the  covenants  described  herein  under  "Covenants,"
clauses (c) and (d) under "Events of Default" with respect to such clauses (iii)
and (iv) under "Consolidation, Merger and Sale of Assets" and such covenants and
clauses (e) and (f) under  "Events of Default"  shall be deemed not to be Events
of Default,  upon, among other things, the deposit with the relevant Trustee, in
trust, of money and/or U.S.  Government  Obligations that through the payment of
interest and principal in respect  thereof in  accordance  with their terms will
provide money in an amount sufficient to pay the principal of, premium,  if any,
and accrued  interest on the Senior Notes or Senior  Discount Notes, as the case
may be, on the Stated  Maturity of such payments in accordance with the terms of
the relevant  Indenture and Notes, the satisfaction of the provisions  described
in clauses (B)(ii),  (C) and (D) of the preceding  paragraph and the delivery by
the Company to the relevant Trustee of an Opinion of Counsel to the effect that,
among other  things,  the Holders will not  recognize  income,  gain or loss for
federal  income tax  purposes  as a result of such  deposit  and  defeasance  of
certain  covenants  and Events of Default and will be subject to federal  income
tax on the same  amount  and in the same  manner  and at the same times as would
have been the case if such deposit and defeasance had not occurred.

   Defeasance  and Certain  Other  Events of  Default.  In the event the Company
exercises its option to omit compliance with certain covenants and provisions of
either  Indenture with respect to the Senior Notes or Senior  Discount Notes, as
the case may be, as described in the  immediately  preceding  paragraph and such
Notes are  declared  due and payable  because of the  occurrence  of an Event of
Default that  remains  applicable,  the amount of money  and/or U.S.  Government
Obligations  on deposit with the  relevant  Trustee  will be  sufficient  to pay
amounts due on such Notes at the time of their  Stated  Maturity  but may not be
sufficient  to pay  amounts  due on such  Notes at the time of the  acceleration
resulting  from such Event of Default.  However,  the Company will remain liable
for such payments.

                                       120

<PAGE>

MODIFICATION AND WAIVER

   Modifications and amendments of the respective  Indentures may be made by the
Company, the Guarantors and the relevant Trustee with the consent of the Holders
of not less than a majority  in  aggregate  principal  amount at maturity of the
outstanding Senior Notes or Senior Discount Notes, as the case may be; provided,
however, that no such modification or amendment may, without the consent of each
Holder affected thereby,  (i) change the Stated Maturity of the principal of, or
any installment of interest on, any Note,  (ii) reduce the principal  amount of,
or premium, if any, or interest on, any Note, (iii) change the place or currency
of payment of principal of, or premium,  if any, or interest on, any Note,  (iv)
impair the right to  institute  suit for the  enforcement  of any  payment on or
after the Stated  Maturity  (or,  in the case of a  redemption,  on or after the
Redemption  Date)  of any  Note,  (v)  reduce  the  above-stated  percentage  of
outstanding  Senior  Notes or Senior  Discount  Notes,  as the case may be,  the
consent  of whose  Holders  is  necessary  to  modify  or amend  the  applicable
Indenture, (vi) waive a default in the payment of principal of, premium, if any,
or interest on the Senior Notes or Senior  Discount  Notes,  as the case may be,
(vii)  release the  Guarantors  from the Senior  Notes  Guarantee  or the Senior
Discount Notes Guarantee, as the case may be, or (viii) reduce the percentage or
aggregate  principal  amount at maturity of  outstanding  Senior Notes or Senior
Discount  Notes,  as the case may be, the consent of whose  Holders is necessary
for waiver of compliance with certain provisions of the applicable  Indenture or
for waiver of certain defaults.

NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS, OR
EMPLOYEES

   The Indentures provides that no recourse for the payment of the principal of,
premium,  if any, or interest on any of the Notes or for any claim based thereon
or otherwise in respect  thereof,  and no recourse under or upon any obligation,
covenant or agreement of the Company in the Indentures,  the Pledge Agreement or
in any of the Notes or because of the creation of any  Indebtedness  represented
thereby, shall be had against any incorporator,  stockholder, officer, director,
employee  or  controlling  person  of the  Company  or of any  successor  Person
thereof.  Each  Holder,  by  accepting  the Notes,  waives and releases all such
liability.

CONCERNING THE TRUSTEES

   The Indentures provide that, except during the continuance of a Default,  the
Trustees will not be liable,  except for the  performance  of such duties as are
specifically set forth in such  Indentures.  If an Event of Default has occurred
and is  continuing,  the Trustees  will use the same degree of care and skill in
its exercise as a prudent person would exercise under the  circumstances  in the
conduct of such person's own affairs.

   The Indentures and provisions of the Trust Indenture Act of 1939, as amended,
incorporated  by  reference  therein  contain  limitations  on the rights of the
Trustees,  should they become  creditors  of the Company,  to obtain  payment of
claims in certain  cases or to realize on  certain  property  received  by it in
respect of any such claims, as security or otherwise. The Trustees are permitted
to engage in other transactions;  provided,  however,  that, if they acquire any
conflicting interest, they must eliminate such conflict or resign.

                           DESCRIPTION OF WARRANTS

   
   The Warrants  will be issued by Orion  pursuant to a warrant  agreement  (the
"Warrant  Agreement")  between Orion and Bankers Trust Company, as warrant agent
(in such capacity,  the "Warrant Agent"), dated the Closing Date. The summary of
certain  provisions of the Warrant Agreement set forth below does not purport to
be  complete  and is  qualified  in its  entirety  by  reference  to the Warrant
Agreement,  including the  definition of certain  terms  therein.  A copy of the
Warrant  Agreement  has been  filed  with the  Commission  as an  exhibit to the
Registration Statement of which this Prospectus is a part.
    

GENERAL

   Each  Warrant,  when  exercised,  will entitle the holder  thereof to receive
shares of  Common  Stock at an  exercise  price of $ per  share  (the  "Exercise
Price").  The  Exercise  Price and the  number of  Warrant  Shares  issuable  on
exercise of a Warrant are both subject to  anti-dilutive  adjustments in certain
cases. See "-- Adjustments" below. The Warrants are not exercisable prior to six
months after the Closing  Date.  Unless  earlier  exercised,  the Warrants  will
expire on the tenth  anniversary  of the Closing Date.  The Warrants will become
separately transferable from the Notes on the earlier of (i) six months from the
date of issuance,  (ii) such date as the Underwriters  may, in their discretion,
deem  appropriate  and (iii) in the event of an Offer to Purchase,  the date the
Company mails notice thereof to holders of the Notes.

   On  the  Closing  Date,   the  Senior  Note  Warrant  Shares  will  represent
approximately  % of the fully  diluted  Common  Stock of Orion,  and the  Senior
Discount Note Warrant Shares will represent approximately % of the fully diluted
Common Stock of Orion.

   The  Warrants  may  be  exercised  by   surrendering  to  Orion  the  Warrant
certificates  evidencing such Warrants with the accompanying form of election to
purchase, properly completed and executed, together with payment of the Exercise
Price. Payment of the Exercise Price by a holder may be made in the form of cash
or a  certified  or  official  bank  check  payable to the order of Orion or the
surrender of  unexercised  Warrant  certificates.  Upon surrender of the Warrant
certificate and payment of the Exercise Price, the Warrant Agent will deliver or
cause to be  delivered,  to or upon the  written  order  of such  holder,  stock
certificates  representing  the number of Warrant Shares or other  securities or
property  to which  such  holder is  entitled  under the  Warrants  and  Warrant
Agreement,  including,  without  limitation,  at Orion's option, cash payable to
adjust for fractional interests in Warrant Shares issuable upon such exercise in
an  amount  equal  to the  Current  Market  Price  (as  defined  in the  Warrant
Agreement) per Warrant Share, as determined on the day immediately preceding the
date the  Warrant  is  presented  for  exercise,  multiplied  by such  fraction,
computed to the nearest whole cent.  If less than all of the Warrants  evidenced
by a Warrant certificate are to be exercised,  a new Warrant certificate will be
issued for the remaining number of Warrants.

   No service charge will be made for  registration of transfer or exchange upon
surrender  of any  Warrant  certificate  at the  office  of  the  Warrant  Agent
maintained  for that purpose.  Orion may require  payment of a sum sufficient to
cover any tax or other  governmental  charge  that may be imposed in  connection
with any registration of transfer or exchange of Warrant certificates.

   The holders of the Warrants have no right to vote on matters submitted to the
stockholders  of Orion or to receive notice of meetings of  stockholders  or any
other  rights of  stockholders  of Orion,  including  any right to receive  cash
dividends.  The holders of the Warrants  have no  preemptive  rights and are not
entitled  to share in the  assets  of  Orion  in the  event of the  liquidation,
dissolution or winding up of Orion's affairs.

ADJUSTMENTS

   The number of Warrant  Shares that may be purchased  upon the exercise of the
Warrants and the Exercise  Price will both be subject to  adjustment  in certain
events including (i) the payment by Orion of dividends (or other  distributions)
on  Common  Stock  payable  in shares of such  Common  Stock or other  shares of
Orion's   capital   stock,   (ii)   subdivisions,   combinations   and   certain
reclassifications of Common

                                       122

<PAGE>

   
Stock,  (iii) the  issuance  of Common  Stock or of rights,  options or warrants
entitling the holder to subscribe  for shares of Common Stock,  or of securities
convertible into or exchangeable for shares of Common Stock, for a consideration
per share  which is less than  $14.00  per share of the Common  Stock,  (iv) the
distribution  to all  holders  of Common  Stock of any of Orion's  assets,  debt
securities  or any rights or  warrants to purchase  securities  (excluding  cash
dividends or other cash distributions from current or retained earnings) and (v)
in the discretion of Orion's Board of Directors. In addition, the Exercise Price
may be reduced in the event of purchase of shares of Common Stock  pursuant to a
tender or  exchange  offer  made by Orion or any  subsidiary  thereof at a price
greater  than the  Current  Market  Price of the  Common  Stock at the time such
tender or exchange offer expires.    

   In the event of a taxable  distribution  to  holders  of Common  Stock  which
results  in an  adjustment  to the  number of  shares  of Common  Stock or other
consideration for which a Warrant may be exercised,  the holders of the Warrants
may, in certain circumstances, be deemed to have received a distribution subject
to United States  Federal income tax as a dividend.  See "Certain  United States
Federal Income Tax Consequences."

   No adjustment in the Exercise Price will be required  unless such  adjustment
would  require an  increase  or  decrease  of at least one  percent  (1%) in the
Exercise Price; provided, however, that any adjustment which is not made will be
carried forward and taken into account in any subsequent adjustment.

   In the case of certain reclassifications,  redesignations, reorganizations or
changes in the number of outstanding shares of Common Stock or consolidations or
mergers of Orion or the sale of all or substantially all of the assets of Orion,
each Warrant shall  thereafter be exercisable  for the right to receive the kind
and  amount of shares of stock or other  securities  or  property  to which such
holder  would have been  entitled as a result of such  consolidation,  merger or
sale had the Warrants been exercised immediately prior thereto.

RESERVATION OF SHARES

   At the time of  issuance  of the  Warrants,  Orion will have  authorized  and
reserved  for  issuance  such  number  of  shares  of  Common  Stock as shall be
initially  issuable  upon the  exercise of the  Warrants.  Such shares of Common
Stock, when paid for and issued must be duly and validly issued,  fully paid and
non-assessable, and not subject to any preemptive rights.

AMENDMENT

   From time to time,  Orion and the Warrant  Agent,  without the consent of the
holders of the  Warrants,  may amend or  supplement  the Warrant  Agreement  for
certain   purposes,   including,   without   limitation,   curing   defects   or
inconsistencies  or making any change  that does not,  in the opinion of Orion's
Board of Directors,  have a material adverse effect on the rights of any holder.
Other amendments or supplements to the Warrant  Agreement  generally require the
written consent of the holders of a majority of the then  outstanding  Warrants.
The consent of each holder of the  Warrants  affected  shall be required for any
amendment  pursuant to which the Exercise Price would be increased or the number
of Warrant Shares purchasable upon exercise of Warrants would be decreased.

REGISTRATION REQUIREMENTS

   The Company is required, under the terms of the Warrant Agreement, to use its
best efforts to maintain the  effectiveness  of a  registration  statement  with
respect to the issuance of the Warrant Shares until the earlier of (i) such time
as all  Warrants  have  been  exercised  and (ii) the tenth  anniversary  of the
Closing  Date.  During any  consecutive  365-day  period  while the Warrants are
exercisable,  the Company will have the ability to suspend the  availability  of
such  registration  statement for up to two  15-consecutive-day  periods (except
during the 30 days  immediately  prior to the expiration of the Warrants) if the
Company's  Board of  Directors  determines  in good  faith that there is a valid
purpose for the  suspension  and provides  notice of such  determination  to the
holders at their addresses  appearing in the register of Warrants  maintained by
the Warrant Agent.

                                       123

REPORTS

   So long as any  Warrants  remain  outstanding,  and  whether or not any Notes
remain  outstanding,  the  Company  will cause  copies of the  reports and other
documents  described  under  "Description  of Notes --  Commission  Reports  and
Reports to Holders" to be filed with the Warrant  Agent and mailed to holders of
Warrants at their addresses in the register maintained by the Warrant Agent.

                BOOK-ENTRY SYSTEM; SETTLEMENT; DELIVERY AND FORM

GENERAL

   The Units will be issued in the form of one or more fully registered Units in
global form ("Global Units"), each comprised of one or more Notes in global form
("Global  Notes") and one or more Warrants in global form  ("Global  Warrants").
The Global Units,  Global Notes and Global  Warrants are  sometimes  referred to
herein  as the  "Global  Securities."  Except  in  those  limited  circumstances
described  below,  Units,  Notes or Warrants in definitive  form  ("Certificated
Units,"  "Certificated  Notes" and "Certificated  Warrants,"  respectively,  and
sometimes  referred to collectively as  "Certificated  Securities")  will not be
issued.

   Upon issuance of the Global  Securities,  the  Depository or its nominee will
credit, on its book-entry  registration and transfer system, the number of Units
represented by such Global  Securities to the accounts of institutions that have
accounts with the Depository or its nominee ("participants"). The accounts to be
credited  shall be  designated  by the  Underwriters.  Ownership  of  beneficial
interests in the Global  Securities  will be limited to  participants or persons
that may hold interests through  participants.  Ownership of beneficial interest
in such Global  Securities  will be shown on, and the transfer of that ownership
will be effected  only  through,  records  maintained  by the  Depository or its
nominee (with respect to participants' interests) for such Global Securities, or
by  participants  or persons  that hold  interests  through  participants  (with
respect to  interests  of persons  other  than  participants).  The laws of some
jurisdictions  require that  certain  purchasers  of  securities  take  physical
delivery of such securities in definitive form. Such laws may impair the ability
to transfer beneficial interests in the Global Securities.

   So long as DTC is the registered holder of any Global Securities, DTC will be
considered  the sole owner and holder of such Units,  Notes or Warrants,  as the
case may be,  represented  by such Global  Securities for all purposes under the
Indentures and the Warrant Agreement and the Units,  Notes and Warrants,  as the
case may be. No beneficial owner of an interest in any Global Securities will be
able to  transfer  that  interest  except in  accordance  with DTC's  applicable
procedures.

   Global Units,  Global Notes and Global  Warrants  shall be  exchangeable  for
corresponding  Certificated  Securities  registered in the name of persons other
than the  Depository or its nominee only if (A) the  Depository (i) notifies the
Company that it is unwilling or unable to continue as Depository  for any of the
Global  Securities or (ii) at any time ceases to be a clearing agency registered
under the Exchange Act, (B) there shall have occurred and be continuing an Event
of Default (as defined in the Indentures)  with respect to the Notes, or (C) the
Company  executes  and  delivers to the Trustee  and or the  Warrant  Agent,  as
appropriate,  an order that the Global  Units,  Global Notes or Global  Warrants
shall be so  exchangeable.  Any  Certificated  Securities will be issued only in
fully  registered form, and in the case of Certificated  Notes,  shall be issued
without coupons in denominations of $1,000 and integral multiples  thereof.  Any
Certificated  Securities  so issued will be registered in such names and in such
denominations as DTC shall request.

   Any payment of principal or interest due on the Notes on any Interest Payment
Date or at  maturity  will be made  available  by the  Company  to the  relevant
Trustee by such date.  As soon as possible  thereafter,  such  Trustee will make
such  payments  to the  Depository  or its  nominee,  as the case may be, as the
registered owner of the Global Notes  representing such Notes in accordance with
existing  arrangements  between  the  Trustee  and the  Depository.  The Company
expects  that the  Depository  or its  nominee,  upon  receipt of any payment of
principal or interest in respect of the Global  Notes,  will credit  immediately
the accounts of the related participants with payments in amounts  proportionate
to their respective  beneficial interests in the principal amount of such Global
Notes as shown on the records of

                                       124

<PAGE>

the Depository. The Company also expects that payments by participants to owners
of beneficial  interests in the Global Securities held through such participants
will be governed by standing instructions and customary practices, as is now the
case with  securities  held for the accounts of customers  registered in "street
name,"  and  will  be the  responsibility  of  such  participants.  None  of the
Underwriters,  the Company,  the  Trustees,  or any payment agent for the Global
Securities  will have any  responsibility  or  liability  for any  aspect of the
records  relating  to or  payments  made  on  account  of  beneficial  ownership
interests in any of the Global  Securities or for  maintaining,  supervising  or
reviewing any records relating to such beneficial ownership interests.

   Unless and until  exchanged in whole or in part for Notes in definitive  form
in  accordance  with  the  terms  of the  Notes,  the  Global  Notes  may not be
transferred  except as a whole by the  Depository to a nominee of the Depository
or by a nominee of the  Depository to the  Depository or another  nominee of the
Depository  or by the  Depository  of any such  nominee  to a  successor  of the
Depository or a nominee of each successor.

THE CLEARING SYSTEM

   With  respect  to the  Depository,  the  Company  believes  as  follows:  the
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York,  a member of the  Federal  Reserve  System,  a  "clearing
corporation"  within the meaning of the New York Uniform  Commercial  Code and a
"clearing  agency"  registered  pursuant to the provisions of section 17A of the
Exchange Act. The Depository was created to hold securities of its  participants
and to facilitate the clearance and settlement of securities  transactions among
its participants in such securities  through  electronic  book-entry  changes in
accounts  of  the  participants,  thereby  eliminating  the  need  for  physical
movements of securities  certificates.  The  Depository's  participants  include
securities  brokers and dealers  (including  each of the  Underwriters),  banks,
trust companies, clearing corporations and certain other organizations,  some of
whom (and/or their  representatives) own the Depository.  Indirect access to the
Depository's  book-entry  system is also  available  to  others,  such as banks,
brokers,  dealers and trust companies that clear through or maintain a custodial
relationship with a participant,  either directly or indirectly.  The Depository
agrees with and  represents  to its  participants  that it will  administer  its
book-entry  system in accordance with its rules and by-laws and  requirements of
law.

SETTLEMENT

   Initial settlement in the Units will be made in same-day funds.

   Investors  electing  to hold their Units  through DTC will follow  settlement
practices applicable to United States corporate debt obligations. The securities
custody  accounts of  investors  will be credited  with their  holdings  against
payment in same-day funds on the settlement date.

   All  payments  of  principal  and  interest  on the Notes will be made by the
Company in same-day funds. The Notes will trade in the Same-Day Funds Settlement
System of the Depository until maturity.  Secondary market trading of the Units,
the  Notes  and  the  Warrants   between  DTC   participants   (other  than  the
depositories) will be settled in same-day funds using the procedures  applicable
to United States corporate debt obligations.

              CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

   
   The following  discussion  summarizes,  subject to the  limitations set forth
below,  the material U.S.  federal income tax  consequences of the  acquisition,
ownership and  disposition  of Units and the Notes and Warrants that  constitute
the Units. The discussion is based upon provisions of the U.S.  Internal Revenue
Code of 1986,  as  amended  (the  "Code"),  its  legislative  history,  judicial
authority,  current  administrative  rulings  and  practice,  and  existing  and
proposed Treasury Regulations, including regulations concerning the treatment of
debt  instruments  issued with original issue discount (the "OID  Regulations"),
all as in effect and  existing  on the date  hereof.  Legislative,  judicial  or
administrative changes or interpretations may be forthcoming that could alter or
modify the validity of the statements and conclusions set forth below.  Any such
changes or  interpretations  may be  retroactive  and could  adversely  affect a
holder of the Notes or  Warrants.  This  discussion  assumes  that the Notes and
Warrants  are or will be held as capital  assets (as defined in Section  1221 of
the Code) by the holders thereof.  Except as otherwise  described  herein,  this
discussion  applies only to a person who is an initial holder  purchasing  Units
pursuant to this offering at the "issue price" (as defined below) and who is (i)
a citizen or resident of the United States for United States  federal income tax
purposes,  (ii) a corporation,  partnership or other entity created or organized
in or under  the  laws of the  United  States  or of any  political  subdivision
thereof,  or (iii) an estate or trust the  income of which is  subject to United
States federal income taxation regardless of its source (a "U.S. Holder").  This
discussion  does not  purport to deal with all  aspects of U.S.  federal  income
taxation that might be relevant to particular holders in light of their personal
investment  circumstances or status, nor does it discuss the U.S. federal income
tax consequences to certain types of holders subject to special  treatment under
the U.S.  federal  income  tax laws,  such as  certain  financial  institutions,
insurance  companies,  dealers in  securities  or foreign  currency,  tax-exempt
organizations,  or persons that hold Notes or Warrants that are a hedge against,
or that are hedged  against,  currency  risk or that are part of a  straddle  or
conversion  transaction,  or persons whose  functional  currency is not the U.S.
dollar.  Moreover, the effect of any applicable state, local or foreign tax laws
is not discussed.

   Hogan &  Hartson  L.L.P.,  tax  counsel  to the  Company,  has  reviewed  the
following  discussion  and is of the opinion that, to the extent it  constitutes
matters of law or legal  conclusions or purports to describe certain  provisions
of the federal tax laws,  the  discussion  is a correct  summary in all material
respects of the matters discussed therein.
    

   THE FOLLOWING  DISCUSSION IS FOR GENERAL  INFORMATION ONLY. EACH PURCHASER IS
STRONGLY  URGED TO CONSULT WITH ITS OWN TAX ADVISORS TO DETERMINE  THE IMPACT OF
SUCH  PURCHASER'S  PERSONAL TAX SITUATION ON THE ANTICIPATED  TAX  CONSEQUENCES,
INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, OF
THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES, WARRANTS OR UNITS.

THE UNITS

   Each Unit is comprised of a Note and a Warrant.  For U.S.  federal income tax
purposes,  the issue price of a Unit must be allocated  between the Note and the
Warrant.  Under the OID Regulations,  the issue price of a Senior Note Unit or a
Senior  Discount  Note Unit should be equal to the offering  price to the public
(not including any bond house,  broker or similar person or organization  acting
in the capacity of an  underwriter,  placement  agent or  wholesaler) at which a
substantial  amount of the Senior Note Units or the Senior  Discount Note Units,
as the case may be,  are  sold.  The  issue  price of a Unit  must be  allocated
between its  component  parts based on their  relative fair market values on the
date of issuance.  Based on the  foregoing,  the Company  intends (i) to treat a
Senior  Note as having  been  originally  issued  with an issue price of $ and a
Senior Note Warrant as having been originally  issued with an issue price of $ ,
and (ii) to treat a Senior Discount Note as having been  originally  issued with
an issue  price of $ and a Senior  Discount  Note  Warrant as having been issued
with an issue price of $ . This allocation by the Company  reflects its judgment
as to the relative values of those instruments at the time of original issuance.
No assurance can be given, however, that the IRS will not challenge the

                                       126

<PAGE>


allocation by the Company of the issue price of the Notes and  Warrants.  If the
Company's  allocation is successfully  challenged,  the issue price, OID accrual
and gain or loss on sale  would be  different  from  that  resulting  under  the
allocation determined by the Company.

   The determination by the Company of the issue price of the Notes and Warrants
will be binding on a holder, unless such holder discloses the use of a different
issue price  allocation on the applicable form attached to such holder's Federal
income tax return for the taxable  year that  includes the  acquisition  date of
such Unit. If a holder  acquires a Unit at a price  different from that on which
the Company's allocation is based, such holder may be treated as having acquired
its Note for an amount greater or less than the amount allocated to such Note by
the Company as set forth  above,  thereby  resulting in  "acquisition  premium,"
"amortizable  bond  premium" or "market  discount,"  as defined  below.  Holders
intending  to use an issue  price  allocation  different  from  that used by the
Company should consult their own tax advisors as to the  consequences to them of
their particular allocation of the issue price of the Units, Notes and Warrants.

SENIOR DISCOUNT NOTES -- ORIGINAL ISSUE DISCOUNT

GENERAL

   The  Senior  Discount  Notes  will bear OID,  and each  U.S.  Holder  will be
required to include in income  (regardless of whether such U.S. Holder is a cash
or  accrual  basis  taxpayer)  in each year,  in advance of the  receipt of cash
payments on such Senior Discount Notes,  that portion of the OID,  computed on a
constant  yield  basis,  attributable  to each day during such year on which the
U.S.  Holder held the Senior  Discount  Notes.  See "Taxation of Original  Issue
Discount" below.

THE AMOUNT OF ORIGINAL ISSUE DISCOUNT

   The amount of OID with respect to each Senior  Discount Note will be equal to
the excess of (i) its "stated redemption price at maturity" over (ii) its "issue
price" (as discussed above).  Under the OID Regulations,  the "stated redemption
price at maturity" of each Senior  Discount Note will include all payments to be
made in respect thereof,  including any stated interest  payments.  Accordingly,
payments on the Senior Discount Notes  (including  principal and stated interest
payments) are not separately included in a U.S. Holder's income as interest, but
rather are  treated  first as  payments  of  previously  accrued OID and then as
payments of principal.

TAXATION OF ORIGINAL ISSUE DISCOUNT

   A U.S. holder of a debt instrument  issued with OID is required to include in
gross income for U.S.  federal income tax purposes an amount equal to the sum of
the "daily  portions"  of such OID for all days during the taxable year on which
the holder holds the debt  instrument.  The daily portions of OID required to be
included in a holder's gross income in a taxable year will be determined  upon a
constant  yield basis by allocating to each day during the taxable year on which
the holder holds the debt  instrument a pro rata portion of the OID on such debt
instrument  which is attributable  to the "accrual  period" in which such day is
included.  Accrual  periods with respect to a Senior Discount Note may be of any
length  selected by the U.S.  Holder and may vary in length over the term of the
Senior  Discount  Note as long as (i) no accrual  period is longer than one year
and (ii) each scheduled  payment of interest or principal on the Senior Discount
Note occurs on either the final or first day of an accrual period. The amount of
the OID  attributable  to each  "accrual  period" will be the product of (i) the
"adjusted  issue price" at the  beginning  of such  accrual  period and (ii) the
"yield to maturity"  of the debt  instrument  (stated in a manner  appropriately
taking into account the length of the accrual  period).  The "yield to maturity"
is the  discount  rate that,  when used in  computing  the present  value of all
payments to be made under the Senior Discount Note,  produces an amount equal to
the issue price of the Senior  Discount  Note.  The "adjusted  issue price" of a
Senior Discount Note at the beginning of an accrual period is generally  defined
as the issue price of the Senior Discount Note plus the aggregate  amount of OID
that accrued in all prior accrual periods,  less any cash payments on the Senior
Discount  Note.  Accordingly,  a U.S.  Holder of a Senior  Discount Note will be
required to include OID thereon in gross income for U.S.

                                       127

<PAGE>

federal  tax  purposes  in  advance  of the  receipt  of cash in respect of such
income.  The amount of OID allocable to an initial  short accrual  period may be
computed using any reasonable method if all other accrual periods,  other than a
final short accrual period,  are of equal length. The amount of OID allocable to
the final accrual period at maturity of a Senior Discount Note is the difference
between (x) the amount  payable at the maturity of the Senior  Discount Note and
(y) the Senior  Discount  Note's adjusted issue price as of the beginning of the
final accrual period.

EFFECT OF MANDATORY AND OPTIONAL REDEMPTIONS ON OID

   In the event of a Change of Control, the Company will be required to offer to
redeem all of the Notes,  including  the Senior  Discount  Notes,  at redemption
prices specified elsewhere herein. The required offer to redeem the Notes should
not  affect,  and  will  not  be  treated  by  the  Company  as  affecting,  the
determination of the yield or maturity of the Senior Discount Notes.

   The Company may redeem the Notes,  including the Senior  Discount  Notes,  in
whole or in part, at any time on or after , 2002, at redemption prices specified
elsewhere herein plus accrued and unpaid interest to the date of redemption. The
OID Regulations contain rules for determining the "maturity date" and the stated
redemption  price at maturity of an instrument that may be redeemed prior to its
stated  maturity  date at the option of the issuer.  Under the OID  Regulations,
solely for  purposes of the  accrual of OID, it is assumed  that the issuer will
exercise any option to redeem a debt  instrument if such exercise will lower the
yield-to-maturity of the debt instrument.  The Company believes that it will not
be presumed to redeem the Senior  Discount Notes prior to their stated  maturity
under these  rules  because  the  exercise  of such  option  would not lower the
yield-to-maturity of the Senior Discount Notes.

TAX BASIS

   A U.S. Holder's initial tax basis in a Senior Discount Note generally will be
equal to the purchase  price paid by such U.S.  Holder for such Senior  Discount
Note. A U.S.  Holder's tax basis in a Senior  Discount Note will be increased by
the amount of OID that is included in such U.S.  Holder's income pursuant to the
foregoing  rules  and will be  decreased  by the  amount  of any  cash  payments
received.

THE SENIOR NOTES

   
   Stated interest payments on the Senior Notes will be taxable to a U.S. holder
when  received  or  accrued  in  accordance  with  such  holder's  method of tax
accounting.  If, as the Company  expects,  the  allocation of issue price to the
Senior Note Warrants and the Senior Notes will  generate a discount  element for
the  Senior  Notes  that is de  minimis,  then the  Senior  Notes  will not bear
original issue discount.  Under the de minimis rule,  there is no original issue
discount on a debt instrument if the debt  instrument is originally  issued at a
discount  that is less than .25%  multiplied  by the  product  of its  principal
amount and number of complete years to maturity from the issue date.     

   In  certain   circumstances,   notes  issued  in  connection  with  the  same
transaction or related transactions may be treated as a single note for purposes
of the OID rules. The Company believes that a substantial portion of each of the
Senior  Notes and the Senior  Discount  Notes will be issued to  purchasers  not
related  to the  Company or to other  purchasers  and who do not  purchase  both
Senior Note Units and Senior  Discount  Note Units in  connection  with the same
transaction or related transactions,  and that, therefore, the aggregation rules
will not apply.

MARKET DISCOUNT, ACQUISITION PREMIUM

   If a U.S.  Holder  acquires a Note for an amount that is less than (i) in the
case of a Senior Note,  its  principal  amount,  or (ii) in the case of a Senior
Discount Note, its revised issue price (generally, adjusted issued price) at the
time of  acquisition,  the amount of such  difference will be treated as "market
discount" for U.S.  federal income tax purposes,  unless such difference is less
than a specified de minimis  amount.  Under the market  discount  rules,  a U.S.
Holder will be required  to treat any  principal  payment on, or any gain on the
sale, exchange, retirement or other disposition of, a Note as ordinary income to

                                       128

<PAGE>

the extent of the market  discount  which has not  previously  been  included in
income and is treated as having accrued on such Note at the time of such payment
or  disposition.  If a U.S.  Holder  makes  a gift  of a  Note,  accrued  market
discount,  if any, will be recognized as if such U.S.  Holder had sold such Note
for a price equal to its fair market value. In addition,  the U.S. Holder may be
required to defer, until the maturity of the Note or the earlier  disposition of
the Note in a taxable  transaction,  the  deduction of a portion of the interest
expense on any  indebtedness  incurred  or  continued  to purchase or carry such
Note.

   Any market  discount will be considered  to accrue on a  straight-line  basis
during the period from the date of acquisition to the maturity date of the Note,
unless the U.S. Holder elects to accrue market  discount on a constant  interest
method.  A U.S.  Holder of a Note may elect to include market discount in income
currently as it accrues (on either a  straight-line  basis or constant  interest
method),  in which case the rules  described  above  regarding  the  deferral of
interest  deductions will not apply. This election to include market discount in
income currently, once made, applies to all market discount obligations acquired
on or after  the  first day of the  first  taxable  year to which  the  election
applies and may not be revoked without the consent of the IRS.

   A U.S.  Holder who purchases a Senior Note at a cost in excess of the greater
of its  principal  amount or the amount  payable on an earlier call date will be
considered to have  purchased the Senior Note with  "amortizable  bond premium,"
and may elect to amortize  such  premium as an offset to interest  income on the
Senior Note. A U.S.  Holder who  acquires a Senior  Discount  Note for an amount
that is greater than the adjusted  issue price of such Senior  Discount Note but
equal to or less than the sum of all  amounts  payable on such  Senior  Discount
Note after the purchase date will be considered  to have  purchased  such Senior
Discount Note at an "acquisition  premium." Under the acquisition  premium rules
of the Code and the OID  Regulations,  the amount of OID which such  holder must
include in its gross  income with respect to such Senior  Discount  Note for any
taxable year will be reduced by the portion of such acquisition premium properly
allocable to such year.

   Proposed  Treasury  regulations  issued on June 27,  1996 would  clarify  the
treatment of bond premium.  The proposed regulations describe the constant yield
method  under which such premium is  amortized  and provide  that the  resulting
offset to interest  income can be taken into account only as a U.S. Holder takes
the corresponding  interest income into account under such U.S. Holder's regular
accounting  method.  In the case of  instruments  that may be redeemed  prior to
maturity,  the proposed  regulations  provide that the premium is  calculated by
assuming that the issuer or holder will exercise or not exercise its  redemption
rights in the manner that maximizes the U.S. Holder's yield. The regulations are
proposed to be effective for debt  instruments  acquired on or after the date 60
days after the date final  regulations  are  published in the Federal  Register.
However,  if a U.S.  Holder elects to amortize bond premium for the taxable year
containing  such  effective  date, the  regulations  would apply to all the U.S.
Holder's debt  instruments  held on or after the first day of that taxable year.
It cannot be  predicted  at this time  whether  these  regulations  will  become
effective  or what,  if any,  modifications  may be made to them  prior to their
becoming effective.

   A U.S.  Holder's tax basis is a Note will be increased by any market discount
previously  included  in such U.S.  Holder's  income and  decreased  by any bond
premium previously amortized by such U.S. Holder.

SALE OR REDEMPTION OF NOTES

   Unless a nonrecognition  provision applies,  the sale,  exchange,  redemption
(including  pursuant to an offer by the Company) or other  disposition of a Note
will be a taxable event for U.S.  federal income tax purposes.  In such event, a
U.S. Holder will recognize gain or loss equal to the difference  between (i) the
amount of cash plus the fair market  value of any  property  received  upon such
sale,  exchange,  redemption or other taxable  disposition (except to the extent
the  consideration  received is attributable to stated interest on a Senior Note
not previously  taken into income,  which  consideration  is treated as interest
income)  and (ii) the U.S.  Holder's  adjusted  tax basis  therein.  Except with
respect to accrued market discount,  such gain or loss should be capital gain or
loss and will be long-term  capital gain or loss if the Note will have been held
by the U.S. Holder for more than one year at the time of such sale, exchange,

                                       129

<PAGE>

redemption or other disposition.  The excess of net long-term capital gains over
net short-term  capital losses is taxed at a lower rate than ordinary income for
certain  non-corporate  taxpayers.  The distinction between capital gain or loss
and  ordinary  income or loss is also  relevant  for  purposes  of,  among other
things, limitations on the deductibility of capital losses.

HIGH-YIELD DISCOUNT OBLIGATIONS

   
   The Senior  Discount Notes will  constitute  "applicable  high yield discount
obligations"  ("AHYDOs") if the yield to maturity of such Senior  Discount Notes
equals or exceeds the sum of the  applicable  federal rate in effect at the time
of the issuance of the Senior  Discount  Notes (the "AFR") plus five  percentage
points.  For January  1997,  the  long-term AFR is 6.44% and the mid-term AFR is
6.01% (based on semi-annual  compounding).  The appropriate AFR depends upon the
weighted  average  maturity of the Senior Discount Notes.  Under Sections 163(e)
and 163(i) of the Code, a C  corporation  that is an issuer of debt  obligations
subject to the AHYDO rules may not deduct any portion of OID on the  obligations
until such portion is actually paid. A debt  obligation is generally  subject to
the AHYDO rules if (i) its  maturity  date is more than five years from the date
of issue,  (ii) its yield to maturity  equals or exceeds the sum of the AFR plus
five percentage  points, and (iii) it bears "significant OID." A debt obligation
will bear  significant  OID for this  purpose if, as of the close of any accrual
period  ending more than five years after  issuance,  the total amount of income
includable  by a holder with respect to the debt  instrument  exceeds the sum of
(i) the total amount of "interest" paid under the obligation before the close of
such  accrual  period  and  (ii)  the  product  of the  issue  price of the debt
instrument and its yield to maturity.  In addition, if the Senior Discount Notes
are AHYDOs,  and if the yield to maturity of the Senior  Discount  Notes exceeds
the sum of the AFR plus six percentage points,  then a portion of the OID on the
Senior  Discount  Notes,  equal to the  product  of the total OID on the  Senior
Discount  Notes times the ratio of (a) the excess of the yield to maturity  over
the sum of the AFR plus six percentage points to (b) the yield to maturity, will
not be  deductible  by the  Company  and will be treated  for some  purposes  as
dividends to the U.S.  Holders of the Senior  Discount Notes (to the extent that
such amounts  would have been  treated as  dividends to the U.S.  Holders of the
Senior  Discount  Notes if they  had  been  distributions  with  respect  to the
Company's  stock).  Amounts  treated as dividends will be  nondeductible  by the
Company,  and may qualify for the dividend received deduction for corporate U.S.
Holders,  but will be treated as OID and not as dividends  for  withholding  tax
purposes. The Company cannot determine whether the Senior Discount Notes will be
AHYDOs until their issue price is  determined  by sale to investors  pursuant to
this offering.     

THE WARRANTS

   Upon the exercise of a Warrant, a U.S. Holder will not recognize gain or loss
(except to the  extent of cash,  if any,  received  in lieu of the  issuance  of
fractional shares of Common Stock) and will have a tax basis in the Common Stock
acquired  pursuant to such exercise equal to such U.S. Holder's tax basis in the
Warrant (which, in the case of an initial holder,  will equal the portion of the
issue price of the Unit properly  allocable to the Warrant,  as described above)
plus the exercise price of the Warrant. The holding period for such Common Stock
so acquired  will commence on the day after the date of exercise of the Warrant.
If any cash is received in lieu of fractional  shares of Common Stock,  the U.S.
Holder will  recognize  gain or loss the amount and  character  of which will be
determined as if such U.S. Holder had received such  fractional  shares and then
immediately  sold  them for  cash.  Similarly,  upon the  sale of  Common  Stock
received upon exercise of a Warrant,  a U.S. Holder will recognize  capital gain
or loss equal to the  difference  between the amount  realized upon the sale and
such U.S. Holder's tax basis in the Common Stock. Such capital gain or loss will
be long-term if, at the time of sale or exchange,  the Common Stock was held for
more than one year.  Distributions  made with  respect to the Common  Stock will
constitute  dividends to the extent paid out of current or accumulated  earnings
and profits of the Company as determined  for U.S.  federal income tax purposes.
To the extent  that a  distribution  exceeds  the  earnings  and  profits of the
Company,  it will be treated as a nontaxable  return of capital to the extent of
the U.S. Holder's adjusted tax basis in the Common Stock. Holders should consult
with their own tax advisors with respect to the particular federal, state, local
and  foreign tax  consequences  to them of the  ownership  of Warrants or Common
Stock.

                                       130

<PAGE>

   The sale of a Warrant will result in the  recognition of capital gain or loss
to the U.S.  Holder in an amount  equal to the  difference  between  the  amount
realized and such U.S.  Holder's tax basis in the Warrant (which, in the case of
an  initial  holder,  will  equal the  portion  of the  issue  price of the Unit
properly  allocable to the Warrant,  as described  above).  Such capital gain or
loss will be long term if, at the time of sale or exchange, the Warrant was held
for more than one year. It is unclear whether the repurchase of a Warrant by the
Company would be treated as a sale or exchange.  If it were not so treated,  any
gain or loss to a holder on such repurchase  would be treated as ordinary income
or loss.

   If a Warrant expires unexercised, a U.S. Holder will recognize a capital loss
equal to such U.S. Holder's tax basis in the Warrant.  Such capital loss will be
long-term if, at the time of the expiration,  the Warrant was held for more than
one year.

   Under  Section  305  of  the  Code,  adjustments  to the  exercise  price  or
conversion ratio of the Warrants which occur under certain circumstances, or the
failure  to  make  such  adjustments,  may  result  in the  receipt  of  taxable
constructive  dividends  by a  U.S.  Holder  (subject  to a  possible  dividends
received  deduction in the case of corporate U.S.  Holders) to the extent of the
Company's  current or  accumulated  earnings and profits,  regardless of whether
there is a distribution of cash or property.

   Subject  to  the  discussion  of  "backup"  withholding  below,  payments  of
principal,  if any, and interest (including OID) by the Company or its agent (in
its capacity as such) to any holder who is a  beneficial  owner of a Note but is
not a U.S. Holder will not be subject to U.S. federal  withholding tax provided,
in the case of interest  (including  OID) that (i) such holder does not actually
or  constructively  own 10% or more of the total  combined  voting  power of all
classes of stock of the  Company  entitled  to vote,  (ii) such  holder is not a
controlled  foreign  corporation  for U.S. tax  purposes  that is related to the
Company through stock  ownership,  and (iii) either (A) the beneficial  owner of
the Note certified to the Company or its agent, under penalties of perjury, that
he is not a U.S.  Holder and  provides  his name and address or (B) a securities
clearing organization,  bank or other financial institution that holds customers
securities  in the  ordinary  course  of its  trade or  business  (a  "financial
institution") certified to the Company or its agent, under penalties of perjury,
that the certification described in clause (A) hereof has been received from the
beneficial  owner  by it or by  another  financial  institution  acting  for the
beneficial owner. A holder of a Note who is not a U.S. Holder,  and who does not
meet the requirements of the preceding  sentence,  would generally be subject to
U.S. federal withholding tax at a flat rate of 30% (or a lower applicable treaty
rate) on payments of interest (including OID) on the Notes.

   If a  holder  of a Note who is not a U.S.  Holder  is  engaged  in a trade or
business  in the  United  States  and  interest  (including  OID) on the Note is
effectively  connected with the conduct of such trade or business,  such holder,
although exempt from U.S. federal  withholding tax as discussed in the preceding
paragraph (or by reason of the delivery of properly  completed Form 4224),  will
be subject to U.S.  federal income tax on such interest  (including  OID) and on
any gain realized on the sale,  exchange or other  dispositions of a Note in the
same manner as if it were a U.S. Holder. In addition, if such Non-U.S. Holder is
a foreign corporation, it may be subject to a branch profits tax equal to 30% of
its effectively  connected earnings and profits for that taxable year, unless it
qualifies for a lower rate under an applicable income tax treaty.

   Subject to the  discussion of "backup"  withholding  below,  any capital gain
realized upon the sale,  exchange or retirement of a Note by a holder who is not
a U.S.  Holder will not be subject to U.S.  federal income or withholding  taxes
unless (i) such gain is  effectively  connected with a U.S. trade or business of
the holder, or (ii) in the case of an individual,  such holder is present in the
United  States for 183 days or more in the  taxable  year of the  retirement  or
disposition and certain other conditions are met.

   Notes held by an  individual  who is neither a citizen  nor a resident of the
United  States  for  U.S.  federal  income  tax  purposes  at the  time  of such
individual's death will not be subject to U.S. federal estate tax, provided that
the income from the Notes was not or would not have been effectively con-

                                       131

nected with a U.S. trade or business of such individual and that such individual
qualified for the exemption from U.S. federal withholding tax (without regard to
the certification requirements) that is described above.

THE WARRANTS

   The  following  discussion  addresses the tax  consequences  to a holder of a
Warrant  who is not a U.S.  Holder of the  ownership,  disposition,  exercise or
lapse of the Warrants.

   For the tax basis of a Warrant  and the tax  basis  and  holding  period of a
share of stock acquired by the exercise of a Warrant, see "-- The Units" and "--
The Warrants," above.  Subject to the conditions  discussed with respect to gain
realized with respect to the Notes under "Tax Consequences to Non-U.S.  Holders"
above, and to the discussion contained in "FIRPTA Treatment of Non-U.S. Holders"
below,  a holder of a Warrant  who is not a U.S.  Holder  will not be subject to
U.S. federal income tax on gain realized on the sale of a Warrant.  Further,  no
gain or loss  will be  recognized  by a holder  of a  Warrant  who is not a U.S.
Holder for U.S. federal income tax purposes upon the exercise of a Warrant.

FIRPTA TREATMENT OF NON-U.S. HOLDERS

   Under the Foreign  Investment  in Real  Property Tax Act of 1980,  as amended
("FIRPTA"),  foreign persons generally are subject to U.S. federal income tax on
capital gain realized on the disposition of any interest (other than solely as a
creditor)  in a  corporation  that is a  United  States  real  property  holding
corporation (a "USRPHC").  For this purpose,  a foreign person is defined as any
holder who is a foreign  corporation  (other than certain  foreign  corporations
that  elect to be  treated  as  domestic  corporations),  a  non-resident  alien
individual,  a non-resident fiduciary of a foreign estate or trust, or a foreign
partnership. Under FIRPTA, a corporation is a USRPHC if the fair market value of
the United States real property  interests held by the corporation is 50 percent
or more of the aggregate fair market value of certain assets of the corporation.

   The Company does not currently  believe that it is a USRPHC.  Thus, a foreign
person  that  holds  Warrants,  or shares  of the  Common  Stock of the  Company
acquired  pursuant  to the  exercise  of such  Warrants,  generally  will not be
subject to the U.S.  federal  income tax on a sale or other  disposition  of the
Warrants or shares of Common Stock.  Even if a corporation  meets the test for a
USRPHC,  a foreign person would  generally not be subject to tax, or withholding
in  respect  to such  tax,  on gain  from a sale or  other  disposition  of such
corporation's  stock solely by reason of the corporation's  USRPHC status if the
stock is  regularly  traded  on an  established  securities  market  ("regularly
traded")  during the  calendar  year in which such sale or  disposition  occurs,
provided that such holder does not own, actually or constructively, stock with a
fair market  value in excess of 5 percent of the fair  market  value of all such
stock  outstanding  at any time  during  the  shorter  of the  five-year  period
preceding such disposition or the holder's holding period.  The Company believes
that the Common Stock will be treated as regularly traded.

BACKUP WITHHOLDING AND INFORMATION REPORTING

   The "backup" withholding and information reporting  requirements may apply to
certain  payments of  principal  and interest  (including  OID) on a Note and to
certain  payments of proceeds of the sale or retirement of a Note.  The Company,
its agent, a broker,  the Trustee or any paying agent,  as the case may be, will
be  required  to  withhold  tax from  any  payment  that is  subject  to  backup
withholding  at a rate of 31% of such payment if the holder fails to furnish his
taxpayer   identification   number   (social   security   number   or   employer
identification  number),  to certify  that such  holder is not subject to backup
withholding,  or to otherwise  comply with the  applicable  requirements  of the
backup  withholding  rules.  Certain  holders  (including,   among  others,  all
corporations)   are  not  subject  to  the  backup   withholding  and  reporting
requirements.

   Under  current  Treasury  Regulations,  backup  withholding  and  information
reporting  will not apply to payments  made by the Company or any agent  thereof
(in its  capacity as such) to a holder of a Note who has  provided  the required
certification under penalties of perjury that it is not a U.S. Holder as set

                                       132

<PAGE>

forth in clause (iii) in the first  paragraph  under  "Non-U.S.  Holders" or has
otherwise  established an exemption  (provided that neither the Company nor such
agent  has  actual  knowledge  that  the  holder  is a U.S.  Holder  or that the
conditions of any other exemption are not in fact satisfied).

   Payments of the proceeds  from the sale by a holder who is not a U.S.  Holder
of a Note made to or through a foreign office of a broker will not be subject to
U.S. information reporting or backup withholding, except that if the broker is a
U.S. person, a controlled foreign corporation for U.S. tax purposes or a foreign
person 50% or more of whose gross income is effectively  connected with a United
States trade or business for a specified  three-year  period,  U.S.  information
reporting may apply to such payments.  Payments of the proceeds from the sale of
a Note to or  through  the United  States  office of a broker is subject to U.S.
information  reporting  and backup  withholding  unless the holder or beneficial
owner certifies as to its non-U.S.  status or otherwise establishes an exemption
from U.S. information reporting and backup withholding.

   Any amounts withheld under the backup  withholding  rules from a payment to a
holder may be claimed as a credit  against such holder's  United States  federal
income tax liability.

   The Company is required to furnish  certain  information to the IRS, and will
furnish  annually  to record  holders  of Notes,  information  with  respect  to
interest and OID accruing during the calendar year. The OID information  will be
based upon the adjusted issue price of the debt instrument as if the holder were
the original holder of the debt  instrument.  No assurance can be given that the
IRS will not challenge the accuracy of the reported information.  Moreover, if a
holder uses an  allocation of the issue price of a Unit between the Note and the
Warrant comprising the Unit that is different from that used by the Company, the
computation  of OID with  respect to such  holder's  Note may  differ  from that
reported by the Company to the IRS and to such  holder.  Subsequent  holders who
purchase  Notes for an amount  other than the  adjusted  issue price and/or on a
date other than the last day of an accrual  period will be required to determine
for  themselves the amount of OID, if any, they are required to include in gross
income for U.S. federal income tax purposes.

                       DESCRIPTION OF CERTAIN INDEBTEDNESS

   The following is a description  of certain  indebtedness  of the Company that
will  be  outstanding   following  the  Transactions.   The  Company  will  need
substantial  additional  capital  to fund the  construction,  launch  and launch
insurance  of Orion 2 and  Orion 3, as well as for  other  purposes.  See  "Risk
Factors -- Need for Substantial Additional Capital" and "Management's Discussion
and Analysis of Financial  Condition  and Results of Operation -- Liquidity  and
Capital Resources."

THE DEBENTURE INVESTMENTS

   The  Debenture  Investment  will  involve the sale on or prior to the Closing
Date of $50 million of convertible junior  subordinated  debentures (the "Junior
Subordinated  Debentures")  to British  Aerospace and the sale of $10 million of
Junior Subordinated Debentures to Matra Marconi Space.

   Terms of Junior  Subordinated  Debentures.  Under an  agreement  among Orion,
British  Aerospace and Matra Marconi Space, the Junior  Subordinated  Debentures
will mature 15 years  following the date of issuance and will bear interest at a
rate of 8.75%  per annum to be paid  semi-annually  in  arrears  solely in Orion
Common  Stock at prices of between  $10.21 and $14 per share,  depending  on the
average  trading  prices of the Common Stock during the  applicable  measurement
period. The Junior Subordinated Debentures (and accrued but unpaid interest) may
be  converted  in whole or in part into  Common  Stock at any time at an initial
conversion  rate of $14 per  share,  as  adjusted  for  stock  splits  or  other
recapitalizations,  certain dividends or issuances of stock to all stockholders,
issuances of stock (or rights to acquire  stock (other than the  Warrants)) at a
price per share below $14.00, and other events.

   Orion  may at any time  (except  during 90 days  after a change  in  control)
redeem  all or part (but not less than 25% on any one  occasion)  of the  Junior
Subordinated  Debentures for cash  consideration  determined by multiplying  the
number  of shares  of  Common  Stock  issuable  upon  conversion  of the  Junior
Subordinated  Debentures by the greater of (i) the average  closing price of the
Orion Common Stock over the 20 trading days  preceding  the  redemption  or (ii)
$17.50 per share.  Alternatively,  Orion may arrange for the  disposition of the
Common Stock received upon the conversion of, or as payment of dividends on, the
Junior Subordinated  Debentures in a public or private offering.  In such event,
the holders of the Junior Subordinated  Debentures will be entitled to receive a
price per share equal to the greater of (a) at least 95% of the average  closing
price of the Common  Stock over the  preceding 20 trading days or (b) $17.50 per
share.  From and  after the time when  less  than $50  million  of Notes  remain
outstanding,  in the  event of a change  of  control  of Orion  (defined  as the
acquisition by any stockholder of a majority of the voting securities of Orion),
either Orion or any holder of the Junior Subordinated  Debentures may, within 90
days after such  change of  control,  force the sale of the Junior  Subordinated
Debentures,  as converted into Common Stock, to Orion for a purchase price equal
to the greater of (a) the price payable in an optional  redemption (as described
above)  and (b) the  price  paid to  holders  of Common  Stock in the  change of
control  transaction.  The Indentures  contain a covenant which will effectively
prohibit Orion from honoring such right.

   The  Junior  Subordinated  Debentures  will  be  subordinated  to  all  other
indebtedness  of the  Company,  including  the  Notes.  The  Trustees  under the
Indentures  with respect to the Senior Notes and the Senior  Discount Notes will
have the right to vote the Junior Subordinated Debentures in connection with any
liquidation or plan of reorganization under the U.S. Bankruptcy Code. The Junior
Subordinated  Debentures will contain minimal covenants and events of default so
long  as $50  million  or  more  of the  Notes  remain  outstanding,  but a more
extensive  set of covenants and events of default will apply after less than $50
million of Notes are outstanding.

   In  connection  with the Debenture  Investments,  Orion has agreed to certain
provisions relating to any mandatory redemption by it of the Junior Subordinated
Debentures,  the  Series C  Preferred  Stock held by  British  Aerospace,  Matra
Marconi  Space or their  respective  affiliates  or the Common  Stock  issued to
British   Aerospace,   Matra  Marconi  Space  upon   conversion  of  the  Junior
Subordinated  Debentures  or the  Series  C  Preferred  Stock or as  payment  of
interest on the Junior  Subordinated  Debentures  or  dividends  on the Series C
Preferred  Stock.  Under its Certificate of  Incorporation,  Orion has the right
mandatorily  to  redeem  the  capital  stock of any  stockholder  to the  extent
necessary to prevent the loss or

                                       134

<PAGE>

secure the  reinstatement  of any  license or  franchise  from any  governmental
agency.  Orion has agreed that any such redemption of such  securities  owned by
British  Aerospace,  Matra Marconi Space or their respective  affiliates,  Orion
will pay an amount for such securities equal to the amount it would have paid if
it had effected such redemption at the price applicable to redemptions  effected
under the terms of the Junior Subordinated  Debentures or the Series C Preferred
Stock,  as the case may be,  which  would be more  favorable  than the price set
forth in the Certificate of Incorporation.

   The  consummation  of the  Debenture  Investments  is  conditioned  upon  the
following:  (i) completion of the Exchange;  (ii) termination of all obligations
of British  Aerospace and Matra  Marconi  Space under their firm and  contingent
capacity  agreements  supporting the Orion 1 Credit  Facility;  (iii) receipt by
Orion of net proceeds from the Offering of at least $225  million;  (iv) Orion's
payment to each of British  Aerospace  and Matra  Marconi Space of its costs and
expenses; and (v) acquisition by Orion of all of British Aerospace's interest in
Orion Asia Pacific in exchange for approximately 86,000 shares of Common Stock.

   Under  the  Orion  1  Satellite  Contract,  Matra  Marconi,  as the  Orion  1
manufacturer,   is  entitled  to  receive  incentive  payments  based  upon  the
performance  of Orion 1 in orbit.  As of September 30, 1996,  Orion Atlantic had
obligations  with a present  value of $21.7  million  with  respect to incentive
payments.   Orion  will  pay  $13  million  in  satellite  incentives  following
completion of the Offering, of which $10 million will be re-invested in Orion by
Matra Marconi Space in Junior Subordinated Debentures.

   The  completion of the Debenture  Investment is a condition to the closing of
the Offering.

TT&C FINANCING

   In November 1993,  Orion Atlantic  entered into a financing  arrangement with
GECC to finance the TT&C facility  (the "TT&C  Financing").  The TT&C  Financing
consists of a note payable in  installments  through June 2002. At September 30,
1996, the Company had outstanding  principal  indebtedness of approximately $7.2
million under the TT&C  Financing  facility.  The interest rate is 7.42% plus an
index rate tied to yields on certain U.S. Treasury securities. The interest rate
at  September  30, 1996 was 13.49%.  The TT&C  Financing  is secured by the TT&C
facility, the contract for Orion's satellite control system and Orion Atlantic's
leasehold  interest  in  the  TT&C  facility  land.  See  Note  4  of  Notes  to
Consolidated Financial Statements.

<PAGE>

                          DESCRIPTION OF CAPITAL STOCK

   The authorized capital stock of Orion consists of 40,000,000 shares of Common
Stock,  par value $.01 per share,  and 1,000,000  shares of preferred stock, par
value $.01 per share.

   The following summary  description of the capital stock of Orion is qualified
in its entirety by reference to the Certificate of  Incorporation  and Bylaws of
Orion. A copy of the Certificate of Incorporation and Bylaws are exhibits to the
Registration Statement of which this Prospectus is a part.

COMMON STOCK

   Common Stock  Outstanding.  As of December 15,  1996,  there were  10,974,121
shares of Common Stock  outstanding,  held by approximately  350 stockholders of
record.

   Dividends.  Subject to  preferences  that may then be  applicable to any then
outstanding  preferred  stock,  holders of Common  Stock are entitled to receive
dividends out of funds legally  available  therefor  when, as and if declared by
the Board of Directors.  Orion has not paid any dividends  upon its Common Stock
and does not plan to pay any dividends on such stock for the foreseeable future.
The  Indentures  contain  covenants  that restrict  Orion's  ability to pay cash
dividends.

   Voting Rights.  Each holder of Common Stock is entitled to one vote per share
of Common  Stock  held by such  holder on all  matters  to be voted  upon by the
stockholders  of Orion.  Holders of shares of Common  Stock are not  entitled to
cumulative voting rights.

   Staggered Terms of Directors.  Under the provisions of Orion's Certificate of
Incorporation  the  members of the Board of  Directors  are  divided  into three
classes with the term of one class expiring each year.  Accordingly,  only those
Directors  of a single  class can be  changed  in any one year and it could take
three years to change the entire  Board.  While Orion  believes that a staggered
Board of Directors is in the best interests of Orion and its stockholders,  such
requirement  may have the  effect of  protecting  management  in  retaining  its
position and discouraging potential acquirers.

   Liquidation  Rights. All shares of Common Stock have equal rights, on a share
for share basis, to receive pro rata the net assets of Orion upon liquidation or
dissolution  after payments to creditors and any holders of preferred  stock, if
any,  then  issued and  outstanding.  There are no  redemption  or sinking  fund
provisions  applicable to the Common  Stock.  All  outstanding  shares of Common
Stock are fully paid and non-assessable.

PREFERRED STOCK

   Orion's  Certificate  of  Incorporation  authorizes the Board of Directors to
issue,  from time to time and without further  stockholder  action,  one or more
series of preferred stock, and to fix the relative rights and preferences of the
shares,  including  voting powers,  dividend  rights,  liquidation  preferences,
redemption  rights, and conversion  privileges.  Because of its broad discretion
with respect to the creation and issuance of preferred stock without stockholder
approval,  the Board of Directors could adversely affect the voting power of the
holders of Common Stock and, by issuing  shares of preferred  stock with certain
voting,  conversion,  and/or redemption rights,  could discourage any attempt to
obtain control of Orion.

SENIOR PREFERRED STOCK

   Preemptive  Rights.  The holders of Senior Preferred Stock have a contractual
"preemptive"  right to purchase a pro rata portion of any equity securities sold
by Orion in the  future on the same  terms  and  conditions  as sold to  others,
subject to  certain  exceptions  for  securities  sold or granted to  employees,
certain small offerings, existing rights to acquire equity securities and public
offerings of securities under the Securities Act, including the Offering.

   Dividends and Conversion.  Dividends on the Senior  Preferred Stock accrue at
8% per annum,  and are  payable as and when  declared  by the Board.  The Senior
Preferred Stock is convertible  into Common Stock at initial prices of $8.50 and
$10.20 per share, subject to anti-dilution adjustments in the case of

                                       136

<PAGE>

recapitalizations  or issuances of Common Stock (other than the Warrant  Shares)
below  the  conversion  price.  Future  issuances  of  Common  Stock  below  the
conversion price could  significantly  increase the percentage of Orion's equity
owned by the  holders of the Senior  Preferred  Stock.  Upon  conversion  of the
Senior Preferred Stock, any accrued and unpaid dividends on the Senior Preferred
Stock will be waived.

   Liquidation Rights. The Senior Preferred Stock has a liquidation
preference equal to the amount invested, which preference increases to the
extent of any accrued and unpaid dividends.

   Voting  Rights.  Holders of the Senior  Preferred  Stock are entitled to vote
with  holders of Series C Preferred  Stock and the Common  Stock,  together as a
single class on an as-if-converted basis.

   Put Rights.  The holders of Senior Preferred Stock have the right to sell the
Common Stock  received upon the  conversion  thereof to Orion upon,  among other
things,  certain mergers,  changes of control or sales of substantially  all the
assets of Orion at the pro rata  interest of such  holders in the  consideration
received,  in the case of certain fundamental  changes, or fair market value. In
the case of  mergers in which the  consideration  to be  received  by holders of
Common Stock is in a form other than cash,  Orion shall pay the  purchase  price
with a  combination  of a  specified  amount of freely  tradable  securities,  a
specified  amount of cash,  and the balance  with a note payable over two years.
The holders of Senior  Preferred  Stock (and any Common Stock  received upon the
conversion  thereof) also have the right to sell such stock (or the common stock
issuable upon conversion  thereof) to Orion  commencing in June 1999 at the fair
market  value of their shares (in the case of Common  Stock) or the  liquidation
value,  including  accrued and unpaid dividends (in the case of Senior Preferred
Stock), in accordance with the following schedule:


                     ON OR AFTER MAY 31,                 PORTION
                    ------------------------           ------------

                    1999 ...................             33 1/3%
                    2000 ...................             66 2/3%
                    2001 ...................                100%



   The holders of Senior  Preferred Stock have agreed to waive exercise of these
rights  for so  long as the  Notes  or  Junior  Subordinated  Debentures  remain
outstanding.  These rights  terminate  upon the closing of a  "Qualified  Public
Offering," as discussed below.

   Tag Along Rights.  Certain  principal  stockholders  of Orion have granted to
CIBC,  Fleet and  Chisholm  the right to have a pro rata  portion  (based on the
percentage  of Common  Stock  outstanding)  of the Common  Stock  issuable  upon
conversion  of the  Senior  Preferred  Stock  included  in any  sales  by  those
principal  stockholders  which  involve  more than 5% of the  Common  Stock then
outstanding.

   Termination of Certain Rights Upon Qualified Public  Offering.  The rights of
the holders of the Senior  Preferred  Stock relating to sale  following  certain
mergers,  changes of control or sale of substantially all assets,  the rights to
sell such stock to Orion  commencing in June 1999 or in connection  with certain
business combinations at fair market value, the preemptive rights and certain of
the  additional  investment  rights  terminate  upon the closing of a "Qualified
Public  Offering" which is defined as a public offering of the Common Stock with
gross proceeds to Orion of not less than $30 million and a public offering price
per share of not less than $25.50.

   Restrictive Covenants;  Representations. The documents relating to the Senior
Preferred  Stock  impose  certain  covenants  on Orion.  The  covenants  include
limitations  on payment of dividends,  redemption of junior  securities  such as
Common Stock,  certain  issuances of senior  securities  (except when the Senior
Preferred  Stock is able to acquire an  equivalent  seniority),  expansion  into
other lines of business or engaging in certain affiliated transactions.  Failure
to comply with those  covenants  (or failure of  representations  to be true and
complete  when made) could  result in an increase in the  dividend on the Senior
Preferred  Stock,  not to exceed an annual  dividend of 14%,  and could give the
holders of the Senior Preferred Stock certain rights to sell such stock to Orion
if the  non-compliance is material or (in certain cases) continues after certain
cure periods.  The Indentures contain a covenant which will effectively prohibit
such  sale to Orion  while any  Notes  are  outstanding.  Orion has the right to
redeem the

                                       137

<PAGE>


Senior  Preferred Stock (subject to limitations  contained in the Indentures) at
its liquidation  value (plus accrued and unpaid  dividends) by paying holders of
Senior  Preferred  Stock that amount and  activating  certain  warrants  (issued
concurrently  with the Senior  Preferred  Stock) to purchase Common Stock at the
conversion price of such Senior  Preferred  Stock.  These warrants do not become
exercisable  unless Orion exercises its right to repurchase the Senior Preferred
Stock.

   Orion's  Right to Force  Conversion  of  Senior  Preferred  Stock.  Orion may
require  conversion of the Senior Preferred Stock (resulting in the cancellation
of accrued but unpaid dividends) if it meets certain public float  requirements,
the  holders  of  Senior  Preferred  Stock  are not  subject  to any  agreements
restricting  the sale of Common  Stock  received on  conversion  and the closing
trading price of the Common Stock for 30 of the 45 trading days preceding notice
of the  required  conversion  has been  above (i)  $21.24  (if  Orion  makes the
conversion  election prior to June 17, 1997) and (ii) $25.50 (if Orion makes the
conversion election on or after June 17, 1997).

SERIES C PREFERRED STOCK

   Dividends. Subject to the preferential rights of Series A Preferred Stock and
Series B Preferred  Stock ranking  senior to the Series C Preferred  Stock,  the
record holders of Series C Preferred Stock are entitled to receive  dividends at
the  rate  of 6% per  annum,  payable  exclusively  (except  in the  event  of a
Liquidation,  as defined  below) in Common  Stock.  Dividends  accrue on a daily
basis  commencing  on the date of  issuance  of each share of Series C Preferred
Stock at the  simple  interest  rate of 6% per  annum.  The  number of shares of
Common  Stock  distributable  in a dividend  on each share of Series C Preferred
Stock is calculated based on the market price of such stock. All preferred stock
issued  after the Closing  Date is required to be  subordinated  to the Series C
Preferred Stock.

   Liquidation rights.  Subject to the liquidation rights for Series A Preferred
Stock and Series B Preferred Stock, in the event of any liquidation, dissolution
or  winding up of Orion (a  "Liquidation"),  each  holder of Series C  Preferred
Stock is entitled to be paid,  before any  distribution  or payment is made upon
the Common Stock or any other series or class of stock of Orion  ranking  junior
to the Series C Preferred  Stock,  an amount in cash equal to the greater of (a)
$1,000 per share (plus an amount equal to all accrued and unpaid  dividends)  of
all shares of Series C Preferred  Stock held by such  holder,  or (b) the amount
which would be distributed with respect to the shares of Common Stock into which
such shares of Series C Preferred Stock are convertible  (assuming conversion of
all outstanding  Series C Preferred Stock)  immediately prior to the record date
for such distribution on an as-converted basis.

   Voting  rights.  The holders of the Series C Preferred  Stock are entitled to
notice of all  stockholders'  meetings in accordance  with Orion's  bylaws,  and
except as otherwise required by law, the holders of the Series C Preferred Stock
are  entitled to vote on all matters  submitted to the  stockholders  for a vote
together  with the holders of Common  Stock and the holders of Senior  Preferred
Stock, voting together as a single class, on an as-converted basis.

   Redemption.  Orion will be  required  to redeem all of the Series C Preferred
Stock in 2022.  Additionally,  at any time after the second  anniversary  of the
date of the  issuance  of the  Series  C  Preferred  Stock  under  the  Exchange
Agreement,  or, if prior to such date,  immediately prior to the consummation of
any  consolidation,  merger or sale in which the successor  entity or purchasing
entity is other than Orion,  Orion, at its option and to the extent it has funds
legally  sufficient  therefor and is permitted to do so by the  Indentures,  may
redeem the shares of Series C Preferred Stock then  outstanding,  in whole or in
part,  for an aggregate  redemption  price of $1,000 per share (plus all accrued
and unpaid dividends thereon).

   Optional Conversion to Common Stock. Holders of Series C Preferred Stock have
the right, at any time, to convert all or a portion of such shares into a number
of shares  of  Common  Stock  equal to the sum of:  (a) the  number of shares of
Common Stock computed by multiplying  the number of shares of Series C Preferred
Stock to be  converted  by $1,000,  and  dividing  the result by the  applicable
Conversion  Price (as such  term is used in the  Certificate  of  Designations),
which initially is $17.50, subject to adjustment,  plus (b) the number of shares
of Common Stock that would be payable if all accrued but unpaid  dividends  were
declared and paid on the shares of Series C Preferred Stock to be converted.

                                       138

<PAGE>

   Mandatory  Conversion  to Common  Stock.  If the closing  price of the Common
Stock over 20 of any 30  consecutive  trading  days is greater  than or equal to
$17.50  (subject to  adjustment),  Orion may require,  by written  notice to all
holders of Series C Preferred  Stock,  the conversion of all of the  outstanding
Series C  Preferred  Stock into a number of shares of Common  Stock equal to the
sum of: (a) the number of shares of Common  Stock  computed by  multiplying  the
number of shares of Series C  Preferred  Stock to be  converted  by $1,000,  and
dividing the result by the applicable  Conversion Price (as such term is used in
the Certificate of Designations)  then in effect,  plus (b) the number of shares
of Common Stock that would be payable if all accrued but unpaid  dividends  were
declared and paid on the shares of Series C Preferred Stock to be converted.  If
Orion requires the mandatory  conversion of the Series C Preferred  Stock within
two years from the initial  date of  issuance  of the Series C Preferred  Stock,
then the  number of shares of Common  Stock  into  which the  shares of Series C
Preferred  Stock are  converted  will be  increased  by the  number of shares of
Common Stock that would be payable if Orion were  immediately to declare and pay
all  dividends  that in the  absence of  conversion  would have  accrued on such
shares  of  Series C  Preferred  Stock  over the six  month  period  immediately
following the date of such mandatory  conversion;  provided,  however,  that the
total dividends,  including any additional  amounts in respect of dividends paid
as a result  of a  required  conversion,  will not be less  than the  amount  of
dividends  that would have  accrued  on all  outstanding  shares of the Series C
Preferred Stock during one full year following the date of issuance.

WARRANTS AND OPTIONS

   As of December  15, 1996,  there were  warrants  and options  outstanding  to
purchase an  aggregate of  1,193,721  shares of Common Stock at exercise  prices
ranging from $8.16 to $14.00 per share,  with a weighted  average exercise price
of $10.31 per share.  Holders of Series A Preferred Stock have options to invest
an additional  approximately  $350,000 in similar  preferred  stock (except that
such similar  preferred stock would be convertible at any time into Common Stock
at a price based upon the date when the option is exercised  within a range from
$10.20 to $17.00 per share of Common  Stock).  The  holders of Senior  Preferred
Stock also hold  certain  warrants to purchase  Common  Stock at the  conversion
price of such Senior Preferred Stock.  These warrants do not become  exercisable
unless Orion exercises its right to repurchase the Senior  Preferred  Stock. The
warrants and options  contain  provisions for the adjustment of exercise  prices
and  numbers  of shares  subject  thereto  in certain  events,  including  stock
dividends, stock splits, reorganizations, reclassifications or mergers.

REGISTRATION RIGHTS

   Series A Preferred Stock and Series B Preferred  Stock;  SS/L. The holders of
Series A  Preferred  Stock and Series B  Preferred  Stock and SS/L (an  existing
stockholder)  are  entitled  to  include  their  shares  of  Common  Stock  in a
registered  offering  (not  including  the  Offering) of  securities by Orion (a
"piggy-back"  registration)  for  its own  account  or for  the  account  of its
stockholders. If Orion proposes to register any shares of its Common Stock under
the  Securities  Act (other than for an offering  primarily  to  employees or in
connection with a merger or acquisition),  the holder of registration rights may
request that Orion include in the registered offering shares held by such holder
or which the holder would receive upon conversion or exercise.  If so requested,
Orion must use its best efforts to include in the registered offering all shares
requested,  provided,  among other conditions,  that the managing underwriter of
such  offering has the right to limit or exclude  entirely such shares of Common
Stock from such offering. Orion is required to bear all registration and selling
expenses,  other than underwriting  discounts,  selling commissions,  applicable
stock transfer taxes, and certain registration fees and expenses,  in connection
with such piggy back registrations.

   The  holders of Series A Preferred  Stock and Series B  Preferred  Stock have
demand rights (including two "long form" and an unlimited number of "short-form"
registrations) to require Orion to register the securities held by them, subject
to certain  conditions.  Orion is required to bear all  registration and selling
expenses,  other than underwriting  discounts,  selling commissions,  applicable
stock transfer taxes, and certain registration fees and expenses,  in connection
with such demand registrations.

   Series C Preferred Stock. Pursuant to the Registration Rights Agreement to be
entered into between  Orion and the Limited  Partners,  Orion will grant certain
registration rights to the Limited Partners, as summarized below.

                                       139

<PAGE>

   o Shelf  Registration  Rights.  Orion will prepare and as soon as practicable
(but no later than 15 days  after)  after 180 days have  passed from the date of
issuance  of the Series C Preferred  Stock (the  "Lockup  Period"),  cause to be
filed a "shelf" registration statement of Orion (the "Initial Shelf Registration
Statement")   which  covers  the  registration  of  any  and  all  the  Eligible
Registrable  Securities  each  holder  elects to  include in the  Initial  Shelf
Registration  Statement.  "Eligible  Registrable  Securities" means the Affected
Shares (as defined below -- see "Shares  Eligible for Future Sale")  issuable to
the Limited Partners pursuant to the Exchange Agreement, up to the 25% Limit (as
defined below -- see "Shares Eligible for Future Sale").

   Orion will be  obligated to file  additional  shelf  registration  statements
providing for the registration of the Eligible Registrable Securities which have
not been registered previously.

   o Demand  Registration of Underwritten  Offerings.  At any time following the
expiration  of the  Lockup  Period,  one or more of the  holders of the Series C
Preferred  Stock  may  request  that  Orion  effect  a  registration  under  the
Securities  Act of all of their  Eligible  Registrable  Securities  in a sale of
securities to an underwriter or underwriters of securities for reoffering to the
public (an  "Underwritten  Offering").  Each such request for registration  must
involve shares worth at least $17.5 million in market value.

   o Piggy-back  Registration Rights. If at any time following the expiration of
the Lockup Period,  Orion proposes to effect a registration  of the Common Stock
(whether for its own account or for the account of others) under the  Securities
Act,  other than a "shelf" or  "demand"  registration  as  described  above or a
registration  of  securities  in  connection  with  a  business  acquisition  or
combination  or an  employee  benefit  plan,  Orion  will,  subject  to  certain
provisions  described  in the  Registration  Rights  Agreement,  include in such
registration all Eligible Registrable Securities with respect to which Orion has
received  written  requests for  inclusion  therein.  Orion will pay any and all
Registration  Expenses  (as  such  term  is  used  in  the  Registration  Rights
Agreement)  incident  to the  filing  of each  such  registration  statement  or
otherwise  incident  to the  performance  of or  compliance  by  Orion  with the
provisions of the Registration Rights Agreement relating to such registration.

   Junior  Subordinated  Debentures.  The shares of Common Stock  issuable  upon
conversion of, or as dividends on, the Junior Subordinated  Debentures will have
the following registration rights:

   o Shelf  Registration  Rights.  Orion  will be  obligated  to  include in the
"shelf"  registration  statement  filed with  respect to the Series C  Preferred
Stock  (to  be  filed   approximately   six  months  after  the  Closing   Date)
approximately  360,000  shares of Common  Stock issued as payment of interest on
the Junior  Subordinated  Debentures or previously  issued to British  Aerospace
pursuant  to a warrant  or the OAP  Acquisition.  Orion also will  prepare  and,
within  one  year  after  the  date  of  issuance  of  the  Junior  Subordinated
Debentures,  cause to be filed a shelf  registration  statement  of Orion  which
covers the  registration  of any and all shares of Common  Stock  issuable  upon
conversion of the Junior  Subordinated  Debentures each holder elects to include
in such shelf registration statement. If not all shares of Common Stock issuable
upon  conversion of the Junior  Subordinated  Debentures  are  registered in the
initial shelf registration statement, Orion will be obligated to file additional
shelf registration statement(s) to register such unregistered shares.

   o Demand Registration of Underwritten  Offerings.  Any one or more holders of
the Junior Subordinated  Debentures may request that Orion effect a registration
under the Securities Act of all or not less than $20 million of shares of Common
Stock  issuable  upon  conversion  of the Junior  Subordinated  Debentures in an
Underwritten   Offering.   Matra   Marconi  Space  may  request  a  single  such
registration  of at least $10 million of shares of Common  Stock.  The number of
requests is not  limited,  but the Company  will not be obligated to effect more
than one Underwritten Offering in any 12 month period, or two such registrations
during the 12-month period in which the Company effects a registration requested
by Matra Marconi  Space.  Orion will pay any and all  Registration  Expenses (as
defined in the relevant registration rights agreement) incident to the filing of
each registration statement for an Underwritten Offering.

   o Piggy-back  Registration Rights. If Orion proposes to effect a registration
of the Orion  Common  Stock  (whether  for its own account or for the account of
others) under the Securities Act, other than a "shelf" or "demand"  registration
as described above or a registration of securities in connection with a

                                       140

<PAGE>

business  acquisition or combination  or an employee  benefit plan,  Orion will,
subject to certain  provisions  described in the Registration  Rights Agreement,
include in such registration all shares of Common Stock issuable upon conversion
of the Junior  Subordinated  Debentures with respect to which Orion has received
written requests for inclusion therein.  Orion will pay any and all Registration
Expenses (as such term is used in the Registration Rights Agreement) incident to
the filing of each such  registration  statement  or  otherwise  incident to the
performance  of or compliance by Orion with the  provisions of the  registration
rights agreement relating to a such registration.

   Such  registration  rights  may hinder  efforts  by Orion to  arrange  future
financings  of Orion and may have an adverse  effect on the market  price of the
Common Stock. See "Shares Eligible for Future Sale."

CERTAIN ANTI-TAKEOVER EFFECTS

   Orion's  Certificate of Incorporation  and Bylaws contain certain  provisions
that are intended to enhance the  likelihood of continuity  and stability in the
composition of Orion's Board of Directors and in the policies  formulated by the
Board of Directors,  and to discourage an  unsolicited  takeover of Orion if the
Board of Directors  determines  that such a takeover is not in the best interest
of Orion and its stockholders.  However,  these provisions could have the effect
of discouraging certain attempts to acquire Orion or remove incumbent management
even if some or a majority of Orion's  stockholders were to deem such an attempt
to be in their best  interest,  including  those attempts that might result in a
premium  over  the  market  price  for  the  shares  of  Common  Stock  held  by
stockholders.

   Orion is subject to  Section  203 of the  Delaware  General  Corporation  Law
("Section  203")  which,  subject to certain  exceptions,  prohibits  a Delaware
corporation from engaging in certain business  combinations  with any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder. In general, Section 203 defines an "interested
stockholder"  as any  entity or person  beneficially  owning  15% or more of the
outstanding  voting stock of the corporation and any entity or person affiliated
with or  controlling  or  controlled  by  such  entity  or  person.  A  Delaware
corporation  may  elect  not  to  be  subject  to  Section  203  by  having  its
stockholders  approve an amendment to its certificate of incorporation or bylaws
to such effect. Orion has not made such an election and, therefore,  Section 203
may have an anti-takeover effect with respect to Orion.

   Under the Communications Act, if Orion controlled an FCC radio common carrier
licensee  (which it  presently  does not),  the FCC could  refuse or revoke such
licensee's license if (i) over 25% of Orion was controlled by foreign persons or
entities  and (ii)  the FCC  found  that the  public  interest  would be  served
thereby.  Because of these  provisions,  Orion's  Certificate  of  Incorporation
empowers the Board of  Directors  of Orion to redeem any of Orion's  outstanding
capital  stock  to the  extent  necessary  to  prevent  the loss or  secure  the
reinstatement  of any license or franchise from any  governmental  agency.  Such
stock  may be  redeemed  at the  lesser  of (i) fair  market  value or (ii) such
holder's  purchase  price  (if the  stock  was  purchased  within a year of such
redemption). See "Business -- Regulation" and "Risk Factors -- Approvals Needed;
Regulation of Industry."  The Company has agreed to certain limits on this right
with  respect  to  the  Debenture  Investments.   See  "Description  of  Certain
Indebtedness."

   Orion's  Certificate of  Incorporation  contains a provision (the "Fair Price
Provision")  that  requires the approval of the holders of a majority of Orion's
voting  stock  (other than voting stock held by an  Interested  Stockholder  (as
defined  below))  as a  condition  to a  merger  or to  certain  other  business
transactions  with,  or proposed  by, a holder of 20% or more of Orion's  voting
stock (an  "Interested  Stockholder"),  except in cases  (such as the  Debenture
Investments)  where the Continuing  Directors approve the transaction or certain
minimum price criteria and other procedural  requirements are met. A "Continuing
Director" is a director who is not an Interested  Stockholder or affiliated with
an Interested Stockholder or who was a member of the Board prior to the time the
Interested  Stockholder became an Interested  Stockholder or whose nomination or
election to the Board of Directors is  recommended  or approved by a majority of
the Continuing Directors.  The minimum price criteria generally require that, in
a transaction in which  stockholders are to receive payments,  holders of Common
Stock must  receive a value  equal to the highest  price paid by the  Interested
Stockholder  for Common Stock during the prior two years,  and that such payment
be  made  in  cash  or in the  type  of  consideration  paid  by the  Interested
Stockholder for the greatest  portion of its shares.  Orion's Board of Directors
believes that the Fair Price

                                       141

<PAGE>

Provision  will  help  assure  that  all of  Orion's  stockholders  are  treated
similarly if certain kinds of business  combinations are effected.  However, the
Fair  Price  Provision  may  make  it  more  difficult  to  accomplish   certain
transactions that are opposed by the incumbent Board of Directors and that could
be beneficial to stockholders.

   Orion's  Certificate of Incorporation also requires any person or entity (the
"Acquiring  Stockholder")  who  acquires  or seeks to acquire  shares of capital
stock of the Company that would  increase  such  person's  voting power in Orion
above any of three thresholds (20%, 33%, or 50%) to send a disclosure  statement
to Orion and the other stockholders.  The Acquiring Stockholder must receive the
approval of the holders of a majority  of the other  shares of Orion  before the
Acquiring Stockholder can vote the acquired stock. In addition, if the Acquiring
Stockholder  has  acquired  or is  acquiring  more  than 50% of the  outstanding
capital stock,  the other  stockholders  who vote against such  acquisition  are
entitled to dissent and obtain for their shares, from Orion,  payment equivalent
to the  estimated  fair  value of their  shares.  The  practical  effect of this
requirement is to condition the  acquisition of control of Orion on the approval
of a majority of the pre-existing disinterested stockholders.

   Orion's  Certificate of Incorporation  provides that all actions taken by the
stockholders  must be taken at an annual or  special  meeting  of  stockholders.
Under the Bylaws,  special  meetings of the  stockholders of Orion may be called
only by a majority of the  members of the Board of  Directors,  the  Chairman or
stockholders  owning in the aggregate at least 35% of the outstanding  shares of
capital  stock of Orion  entitled to vote.  Orion is not  obligated to hold more
than one special  meeting called by  stockholders  during any six-month  period.
Stockholders are required to comply with certain advance notice  provisions with
respect to any  nominations  of  candidates  for  election  to Orion's  Board of
Directors or other proposals  submitted for stockholder  vote.  These provisions
may have the  effect of  deterring  hostile  takeovers  or  delaying  changes in
control or management of Orion.

   Orion's  Certificate  of  Incorporation  and Bylaws provide that the Board of
Directors of Orion is divided into three classes of directors  serving staggered
three-year  terms. The  classification  of directors has the effect of making it
more  difficult  for  stockholders  to change  the  composition  of the Board of
Directors  in a  relatively  short  period  of time.  The  authorized  number of
directors  may be  changed by  resolution  of the Board of  Directors  or by the
holders of at least  two-thirds of the voting power of all  outstanding  shares,
and directors may not be removed without cause.

   The foregoing  provisions of Orion's Certificate of Incorporation and Bylaws,
except for those dealing with the  liability of  directors,  may not be altered,
amended or repealed  without the approval of the holders of at least  two-thirds
of the voting power of all  outstanding  shares entitled to vote thereon and the
affirmative vote of the Board of Directors.

LISTING

   The Common  Stock is quoted on the Nasdaq  National  Market under the trading
symbol "ONSI."

TRANSFER AGENT

   The transfer agent and registrar for the Common Stock is Fleet National Bank.

                                       142

<PAGE>

                         SHARES ELIGIBLE FOR FUTURE SALE

   Upon completion of the Merger and the Exchange,  there will be  approximately
25.9  million  shares of Common  Stock  outstanding  on a fully  diluted  basis,
assuming a closing of the  Transactions  as of January 30,  1997.  Approximately
14.5  million  of  these  shares  will  initially  be  held by  Orion's  current
stockholders,  all of which will be freely  transferable  without restriction or
further registration under the Securities Act, other than the 5.5 million shares
held by "affiliates" of Orion, as that term is defined under the Securities Act.
The shares held by  affiliates  are expected to be eligible for sale pursuant to
Rule 144 under the Securities Act. See "Principal Stockholders."

   In  general,  under Rule 144 as  currently  in effect of Orion,  a person (or
persons  whose  shares  are  aggregated),   including  an  affiliate,   who  has
beneficially  owned shares for at least two years  (including the holding period
of any prior owner  other than an  affiliate)  is  entitled to sell,  within any
three-month  period,  a number of shares that does not exceed the greater of (i)
1% of the then outstanding shares of Common Stock (approximately  111,000 shares
outstanding  immediately  after the  Transactions)  or (ii) the  average  weekly
trading volume in the Common Stock during the four calendar weeks preceding such
sale,  subject to the filing of a Form 144 with respect to such sale and certain
other limitations and restrictions.  In addition,  a person who is not deemed to
have been an affiliate of Orion at any time during the 90 days preceding a sale,
and who has  beneficially  owned the shares of Orion  proposed to be sold for at
least three  years,  would be  entitled  to sell such  shares  under Rule 144(k)
without regard to the requirements described above.

   The Limited Partners,  as owners of the Series C Preferred Stock, and British
Aerospace  and  Matra  Marconi  Space,  as  owners  of the  Junior  Subordinated
Debentures,  will own the remaining 11.4 million  shares of Common Stock,  which
will be issuable upon the conversion of such securities. All of such shares will
be deemed to be  "restricted  securities"  as that term is  defined in Rule 144.
Moreover,  each  Exchanging  Partner  will  enter  into a  Transfer  Restriction
Agreement  regarding  the transfer of the shares of Common Stock  issuable  upon
conversion,  or  dividends  on the Series C  Preferred  Stock.  Pursuant  to the
applicable  Transfer  Restriction  Agreement,  each  Exchanging  Partner may not
transfer any shares of Common Stock issued upon conversion of shares of Series C
Preferred  Stock or as  dividends  on such Series C Preferred  Stock  ("Affected
Shares")  without the prior written  consent of the Company until the expiration
of the Lockup  Period  (other  than  certain  transfers  to  affiliates).  Also,
pursuant to the  applicable  Transfer  Restriction  Agreement,  each  Exchanging
Partner  agrees  that it will not  transfer  during any 90 day  period  Affected
Shares that  collectively  represent  more than 25% of the  aggregate  number of
shares of Common Stock issuable upon  conversion of the Series C Preferred Stock
received by such  Exchanging  Partner  pursuant to the Exchange  Agreement or as
dividends  on such Series C Preferred  Stock (the "25%  Limit")  unless any such
transfer  is (i)  pursuant to an  underwritten,  public  offering  pursuant to a
registration  statement  under the Securities  Act, (ii) pursuant to a tender or
exchange  offer made by or on behalf of the Company or a  third-party,  (iii) in
connection with a merger, consolidation, sale of all or substantially all of the
assets,  recapitalization  or  similar  transaction  involving  Orion,  or  (iv)
pursuant  to a  transaction  not  involving  a public  distribution  or offering
registered  under the  Securities  Act and not made through a broker,  dealer or
market-maker   pursuant  to  Rule  144  (including  a  pledge  that  meets  such
requirements);  provided, however, that prior to any transfer of Affected Shares
under  clause (iv) above and prior to any  transfer of Series C Preferred  Stock
other than under the  circumstances  set forth in clauses  (i),  (ii),  or (iii)
above,  the  transferee  shall  execute  and  deliver to the  Company a transfer
restriction   agreement   substantially  similar  to  the  Transfer  Restriction
Agreement the  transferor  originally  entered into  (omitting the Lockup Period
provision  noted above).  The 25% Limit  described  above will  terminate on the
fifth anniversary of the Closing Date.

   The Limited Partners and holders of the Junior  Subordinated  Debentures will
be granted  certain  shelf,  demand and  "piggy-back"  registration  rights with
respect to the Common Stock issuable upon conversion of Series C Preferred Stock
to be received by them in the Exchange or such Junior  Subordinated  Debentures,
respectively,  and the Common Stock  issuable as  dividends  thereon or interest
with respect thereto. See "Description of Capital Stock -- Registration Rights."

   No  predictions  can be made as to the effect,  if any,  that sales of Common
Stock or the  availability of additional  shares of Common Stock for sale by the
Limited  Partners or other  stockholders of Orion would have on the market price
of such  securities  prevailing from time to time or on the ability of the Orion
to raise additional equity financing.

   Subject to the terms and conditions of the  Underwriting  Agreement dated the
date hereof (the "Underwriting  Agreement") among the Company,  Morgan Stanley &
Co.  Incorporated  and  Merrill  Lynch,  Pierce,  Fenner  &  Smith  Incorporated
(together, the "Underwriters"), each of the Underwriters has severally agreed to
purchase the number of Units set forth opposite its name below:

  Total..................................
                                           ===================== =======================

</TABLE>

   
   The  Underwriting  Agreement  provides  that the  obligation  of the  several
Underwriters  to pay for and accept  delivery  of the Units  offered  hereby are
subject to the approval of certain legal matters by their counsel and to certain
other conditions.  The Underwriters are obligated to take and pay for all of the
Units if any are taken. After the initial offering, the offering price and other
selling terms may, from time to time, be varied by the Underwriters.    

   There is no public  market for the Units and the  Company  does not intend to
apply for listing of the Units, Notes or Warrants on any securities  exchange or
for quotation  through the Nasdaq National Market.  The Company has been advised
by the  Underwriters  that they  intend to make a market in the Units  (prior to
separation) and the Notes and Warrants  (subsequent to separation),  but are not
obligated to do so and may discontinue market making at any time without notice.
Accordingly, no assurance can be given as to the liquidity of the trading market
for the Units, Notes or Warrants.

   The exercise  price of the Warrants will be determined  through  negotiations
between the Company and the Underwriters.

   The Company and the several  Underwriters have agreed to indemnify each other
against certain liabilities, including liabilities under the Securities Act.

   The  appraisal of Orion 1 included in this  Prospectus  has been  prepared by
Ascent   Communications   Advisors,   L.P.,   consultants   in   the   area   of
telecommunications,  as indicated in their  report with  respect  thereto.  Such
appraisal  included  herein is included in reliance  upon the  authority of such
firm as experts.  Ascent has conducted more than thirty satellite valuations and
related  assignments  within the last four years.  Founding  members of Ascent's
senior staff and advisors developed  Ascent's  consulting and valuation practice
in the early 1980's  initially  as owners and  management  of CSP  International
("CSPI"),  a  specialized  communications  consulting  firm.  In 1987,  CSPI was
acquired by Booz, Allen and Hamilton,  where the Ascent team actively  continued
its business strategy and appraisal practice. In 1991 former principals of CSPI,
as well as a former staff member of Goldman  Sachs & Co.,  independently  formed
Ascent to reassume  CSPI's practice from Booz,  Allen and Hamilton.  The Company
has agreed to indemnify Ascent,  its affiliates,  directors,  officers,  agents,
employees and  controlling  persons  against  certain  liabilities and expenses,
including liabilities under the Securities Act.

                APPRAISAL OF ASCENT COMMUNICATIONS ADVISORS L.P.

ORION NETWORK SYSTEMS, INC.

   Ascent has  prepared an  appraisal  estimating  the Fair Market  Value of the
Orion 1 satellite  to be $304 million as of December 1, 1996 (Orion 1 "Valuation
Date").  Ascent  defines  the  Fair  Market  Value of the  satellite,  as of its
Valuation Date, as the price that would be paid by a purchaser and accepted by a
seller of the satellite,  neither under compulsion to buy or sell, respectively,
for delivery of the satellite on its Valuation Date.

   Because events and circumstances  frequently do not occur as expected and for
the reasons  described in this  Prospectus,  there will  usually be  differences
between  projected and actual  results,  and those  differences may be material.
Therefore, no assurance may be given that the appraised value of the assets will
be achieved and reliance should not be placed on such appraised value.

   In addition to  determining  the Fair Market  Value of the Orion 1 Satellite,
Ascent calculated  replacement cost as a measure of Fair Market Value.  However,
we rejected  replacement  cost because,  in our  experience  in-orbit  satellite
systems and related assets have  typically had Fair Market Values  substantially
in excess of replacement cost.

                        REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Orion Network Systems, Inc.

   We have audited the accompanying consolidated balance sheets of Orion Network
Systems,  Inc. as of December  31, 1995 and 1994,  and the related  consolidated
statements of operations,  changes in stockholders'  equity,  and cash flows for
each of the three years in the period ended December 31, 1995.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

   In our opinion, the financial statements referred to above present fairly, in
all material  respects,  the  consolidated  financial  position of Orion Network
Systems, Inc. at December 31, 1995 and 1994, and the consolidated results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1995, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

           (INFORMATION WITH RESPECT TO SEPTEMBER 30, 1996 AND FOR
         THE NINE MONTHS ENDED SEPTEMBER 1995 AND 1996 IS UNAUDITED)

1. ORGANIZATION

   Orion Network Systems, Inc. (Orion) was incorporated in the State of Delaware
on October 26, 1982 (inception) under the name Orion Satellite Corporation,  and
in January  1988,  changed its name to Orion  Network  Systems,  Inc.  Orion has
developed and operates an international satellite  communications system for use
in private communications networks to multinational  businesses and transmission
capacity  for video and  other  program  distribution  services.  Orion's  first
satellite (Orion 1) was  successfully  launched on November 29, 1994. Orion took
delivery of the Orion 1 satellite on January 20, 1995. As a result,  Orion is no
longer  considered a development  stage enterprise  effective  January 1995. For
periods prior to January 1995, Orion was in the development stage.

   Since 1989,  management  has been involved  primarily in  developing  Orion's
partnership, International Private Satellite Partners, L.P. (Orion Atlantic), in
order to raise the necessary  capital to finance the  construction and launch of
up to  two  telecommunications  satellites  in  geosynchronous  orbit  over  the
Atlantic Ocean and to establish a multinational sales and service  organization.
Orion  has been  financed  by  equity  and debt from  individual  and  corporate
investors.  British  Aerospace PLC or its affiliates  (BAe) and Lockheed  Martin
Corporation  or its  affiliates  (Lockheed  Martin) are  stockholders  of Orion,
limited  partners in Orion  Atlantic  and were  significant  contractors  in the
construction and launch of the satellite system.

   In June 1991,  Orion,  through a  wholly-owned  subsidiary,  Orion  Satellite
Corporation  (OrionSat),  received  a license  from the  Federal  Communications
Commission  (FCC)  authorizing  it to construct,  launch and operate a satellite
system comprised of two satellites to provide  international  telecommunications
services. Pursuant to an application by OrionSat, the license was transferred to
Orion  Atlantic on April 19, 1994,  by order of the FCC. In December  1991,  the
initial phase of the  partnership  financing  plan was concluded by a closing on
equity commitments in the form of limited partnership  interests aggregating $90
million and execution of a credit  agreement  related to senior debt commitments
for up to $251  million  (see  further  discussion  in Note 3). Also in December
1991,  notice to proceed with the construction  contract for the first satellite
was given to BAe, the prime contractor.

   OrionSat is the sole  general  partner in Orion  Atlantic  and received a 25%
equity  interest  as of  the  initial  closing  for,  among  other  things,  its
contribution  of certain  rights and  interests  under its FCC license,  certain
contract rights, and other tangible and intangible assets. Orion participates as
a limited partner with a 16 2/3% equity interest and  participates  fully in the
obligations  and rights of the  limited  partnership.  The  aggregate  ownership
interest by Orion and its  subsidiaries  in Orion  Atlantic is 41 2/3% (see Note
3).

   In August 1995, the Company  completed its initial public  offering of common
stock by  selling  4,000,000  common  shares at $14 per share.  Proceeds  to the
Company, net of underwriting discount,  aggregated approximately $52.25 million.
In July 1995,  in  connection  with the planned  initial  public  offering,  the
shareholders  approved a 1 for 1.36 reverse stock split.  All  references in the
consolidated  financial  statements with regard to shares, per share amounts and
share prices have been adjusted for the reverse stock split.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION POLICY

   The consolidated  financial statements include the accounts of Orion, its two
wholly-owned  subsidiaries OrionNet, Inc. (OrionNet) and OrionSat, its 83% owned
subsidiary,  Asia Pacific Space and Communications Ltd. (Asia Pacific) (see Note
7), the Orion Financial  Partnership,  in which Orion holds a 50% interest,  and
Orion Atlantic, in which Orion holds, at December 31, 1995, a 41 2/3% ownership

interest.  Management  control and direction of Orion  Atlantic by OrionSat is a
requirement  of the FCC in order  for Orion  Atlantic  to  continue  to hold the
license  authority  received in June 1991.  OrionSat,  as the general partner of
Orion Atlantic, exercises such control through the provisions of the partnership
agreement.  The amount  reflected  in the balance  sheet as  "Limited  Partners'
interest in Orion Atlantic"  represents  amounts invested by entities other than
Orion (net of syndication  costs related to the investments)  adjusted for those
Limited  Partners'  share of operating  results.  All  significant  intercompany
accounts and transactions have been eliminated.

USE OF ESTIMATES

   The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial  statements and accompanying notes.
Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

   Orion considers all highly liquid investments with a maturity of three months
or less  when  purchased  to be cash  equivalents.  Cash  and  cash  equivalents
includes cash in banks and short term investments, as follows:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES-(Continued)

NET LOSS PER COMMON SHARE

   Net loss per common share is based on the weighted  average  number of common
shares  outstanding  during the  period.  Pursuant  to the  requirements  of the
Securities  and Exchange  Commission,  common  stock  issued and stock  issuable
relating to convertible preferred stock, warrants and options granted within one
year of filing the  registration  statement  relating to the  Company's  initial
public  offering of common  stock were  treated as  outstanding  for all periods
prior to the second quarter of 1995.

INTERIM FINANCIAL STATEMENTS

   The  accompanying  financial  statements as of September 30, 1996 and for the
nine months  ended  September  30, 1995 and 1996 are  unaudited  but include all
adjustments, consisting only of normal recurring accruals, which Orion considers
necessary for a fair  presentation of financial  position and operating  results
for those  interim  periods.  The  operating  results for the nine months  ended
September  30, 1996 are not  necessarily  indicative  of the results that may be
expected for the year ended December 31, 1996.

PROPERTY AND EQUIPMENT

   Property and equipment are carried at cost. Depreciation and amortization are
calculated using the  straight-line  method over their estimated useful lives as
follows:

              Satellite and related equipment .....  10.5 years
              Telecommunications equipment  .......   2-7 years
              Furniture and computer equipment  ...   2-7 years

   Costs incurred in connection with the construction and successful  deployment
of the  satellite  and related  equipment  are  capitalized.  Such costs include
direct contract cost,  allocated indirect costs, launch costs, launch insurance,
construction  period  interest  and the  present  value of  satellite  incentive
payments,  Orion began depreciating the satellite over its estimated useful life
commencing on the date of operational delivery in orbit (January 20, 1995).

   In March  1995,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Statement No. 121,  "Accounting for the Impairment of Long-Lived  Assets and for
Long-Lived  Assets to Be Disposed Of",  which requires  impairment  losses to be
recorded on long-lived  assets used in operations  when indicators of impairment
are present and the  undiscounted  cash flows estimated to be generated by those
assets  are less  than the  assets'  carrying  amount.  Statement  No.  121 also
addresses the accounting for long-lived  assets that are expected to be disposed
of. The effect of adoption was not material.

DEFERRED FINANCING COSTS

   Deferred  financing  costs  related to  obtaining  debt and Orion's  share of
equity  financing for Orion  Atlantic are amortized  over the period the debt is
expected to be  outstanding.  Accumulated  amortization  at September  30, 1996,
December  31,  1995  and  1994  was   $8,589,000,   $6,990,000   and  $4,860,000
respectively.  Amortization  through January 1995 was capitalized as part of the
cost of the satellite.  Costs of  approximately  $3.4 million relating to a debt
offering  which was  postponed  in  November  1995 have  been  charged  to other
expense. 

OTHER ASSETS

   Other  assets  consist   principally  of  FCC  license   application   costs,
organization  costs and  goodwill.  The  Company  began  amortizing  FCC license
application  costs  related  to Orion 1 in  January  1995 and will  continue  to
amortize  these  costs  over  the  estimated   useful  life  of  the  satellite.
Organization   costs  and  goodwill  are  amortized  over  five  and  ten  years
respectively.  Accumulated amortization at September 30, 1996, December 31, 1995
and 1994 was $3,535,000, $3,069,000 and $1,934,000, respectively.

REVENUE RECOGNITION

   Orion's  revenue  results  from  providing   telecommunications  and  related
services.  Revenue is recognized  as earned in the period in which  services are
provided.

   The  following  summarizes  the Company's  domestic and foreign  revenues for
1995:

INTEREST RATE MODIFICATION AGREEMENTS

   Orion  may,  from  time  to  time,  enter  into  interest-rate  swap  and cap
agreements to modify the interest characteristics of its outstanding debt from a
floating to a fixed-rate basis. These agreements involve the receipt of floating
rate amounts in an exchange for  fixed-rate  interest  payments over the life of
the  agreement  without an  exchange of the  underlying  principal  amount.  The
differential  to be paid or  received is accrued as  interest  rates  change and
recognized as an adjustment to interest expense related to the debt. The related
amount  payable to or  receivable  from  counterparties  is included in interest
payable.  The fair  values  of the swap  agreements  are not  recognized  in the
financial statements. (See Notes 5 and 8)

INCOME TAXES

   The Company adopted the provisions of FASB Statement No. 109, "Accounting for
Income Taxes"  effective  January 1, 1993,  and as a result,  uses the liability
method of accounting  for income taxes.  There was no cumulative  effect to this
accounting  charge.  Under this method,  deferred tax assets and liabilities are
determined  based on differences  between  financial  reporting and tax bases of
assets and  liabilities  and are  measured  using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.

   At December 31, 1995,  Orion has  approximately  $51,219,000 in net operating
loss carryforwards which expire at varying dates from 2004 through 2010. The use
of these loss  carryforwards may be limited under the Internal Revenue Code as a
result of ownership changes  experienced by Orion. Due to uncertainty  regarding
its ability to realize the benefits of such net  operating  loss  carryforwards,
the Company has established a valuation allowance for the full amount of its net
operating loss carryforwards.

3. ORION ATLANTIC

   Orion  Atlantic  is  a  Delaware  limited   partnership   formed  to  provide
international private communications networks and basic transponder capacity and
capacity  services  (including  ancillary  ground  services) to  businesses  and
institutions  with  trans-Atlantic  and  intra-European  needs. The business was
organized by OrionSat,  the general  partner of Orion  Atlantic.  The  principal
purposes of Orion Atlantic are to finance the construction, launch and operation
of up to two  telecommunications  satellites  in  geosynchronous  orbit over the
Atlantic Ocean and to establish a multinational sales and service  organization.
OrionSat was granted  final  authority by the FCC on June 27, 1991 to construct,
launch and operate an international  communications  satellite system, including
two orbital slots at 37.5' W.L. and 47' W.L.  OrionSat,  the general partner
of Orion Atlantic, entered into an agreement with Orion Atlantic and its limited
partners  on December  20,  1991,  to convey the FCC license to Orion  Atlantic.
OrionSat filed an application to transfer the satellite  authorization  to Orion
Atlantic  in December  1992;  the  transfer  was granted by the FCC on April 19,
1994.  Effective  January 20,  1995,  Orion  Atlantic is no longer  considered a
development stage enterprise.  For periods prior to January 1995, Orion Atlantic
was considered a development stage enterprise.

   Eight international  corporations,  including Orion,  invested a total of $90
million in equity as limited partners in Orion Atlantic. Orion Atlantic also has
a credit facility which provided up to $251 million for the first satellite from
a syndicate of major  international  banks led by Chase  Manhattan Bank, N.A. In
addition to their equity investments,  the Limited Partners have agreed to lease
capacity on the satellites up to an aggregate $155 million and have entered into
additional  contingent  capacity lease  contracts  ("contingent  call") up to an
aggregate  $271 million,  as support for repayment of the senior debt.  The firm
capacity leases and contingent calls are payable over a seven-year  period after
the first  satellite is placed in service.  In July 1995,  January and July 1996
the Limited  Partners  (excluding the Company) paid $7.6 million,  $18.0 million
and $12.1 million, respectively, pursuant to these contingent calls.

   Satellite  Construction  Contract  -- In  December  1991,  the  contract  for
construction,  launch services,  and launch and commissioning  insurance for two
communications   satellites  went  into  effect  with   OrionSat's   rights  and
obligations  under the contract being assigned to Orion  Atlantic.  During 1993,
Orion Atlantic  terminated its commitment to purchase the second  satellite and,
as a result,  incurred a $5 million  termination charge. Such amount is included
in other income  (expense) in the  accompanying  Statements of  Operations.  The
satellite was constructed by MMS Space Systems, Limited ("MMS Space Systems").

   The fixed base price of the total contract, excluding obligations relating to
satellite  performance,  aggregated  $227  million  and has been  fully  paid at
December 31, 1995.  In addition to the fixed base price,  the contract  requires
payments to be made, in lieu of a further  contract price increase,  aggregating
approximately $44 million through 2006. Such payments are due, generally,  if 24
out of 34 satellite  transponders  are operating  satisfactorily.  Shortly after
acceptance of the satellite in January 1995,  the Company filed a warranty claim
with the satellite  manufacturer relating to one transponder that did not appear
to be  performing in accordance  with contract  specifications.  In August 1995,
Orion Atlantic  received a one time refund of $2.75 million which was applied as
a mandatory prepayment to the senior notes payable -- banks (See Note 5).
   
   The Company believes that since Orion 1 is properly deployed and operational,
based upon industry data and  experience,  payment of the  obligation  mentioned
above is highly  probable and the Company has  capitalized  the present value of
this  obligation  of  approximately  $14.8  million  as part of the  cost of the
satellite.  Payment  of amounts  due under this  obligation  are  delayed  until
payment is permitted  under the senior notes  payable -- banks (See Note 5). The
present  value was  estimated  by  discounting  the  obligation  at 14% over the
expected term,  assuming payment of the incentives begins upon expiration of the
senior notes payable -- banks in 2002.    

   Partnership and Limited  Partners -- OrionSat has the primary  responsibility
for the  control,  management  and  operations  of  Orion  Atlantic.  Under  the
partnership  agreement,  the limited  partners  have  rights of  approval  for a
limited  number  of  matters,  e.g.,  terms  for  acceptance  of  new  partners,
significant budget modifications, and certain borrowings.

   The  financing  and legal  structure of Orion  Atlantic  restricts the use of
partnership  resources to the purposes of constructing,  launching and operating
the  satellite  system.  Cash will be  distributable  by Orion  Atlantic  to the
partners  in the  future  only after  sufficient  operating  revenues  have been
generated to pay satellite  system  operating costs and debt service.  Orion and
OrionSat  will share pro rata with the partners in $28 million of the first $100
million  of cash  available  for  distribution  to the  partners  as a return of
capital.  Thereafter,  operating cash flow is  distributable  based on ownership
interests.

   Redemption of STET Partnership  Interest;  Issuance of New Interest to Orion.
- -- On November 21, 1995 Orion Atlantic redeemed the limited partnership interest
held by STET (the "STET  Redemption").  Such  redemption  was for $11.5 million,
including  $3.5  million of cash and $8.0 million in 12%,  promissory  notes due
through 1997.  STET's firm and contingent  capacity  leases will remain in place
until released by the Banks under the Orion 1 Credit  Facility.  STET's existing
contractual  arrangements  with Orion Atlantic have been modified in a number of
respects, including (i) a reduction of approximately $3.5 million in amounts due
by Orion Atlantic to Telespazio  S.p.A.,  an affiliate of STET,  over a ten-year
period  under  contracts  relating  to the  construction  of  Orion  2,  back-up
tracking,  telemetry  and  command  services  through  a  facility  in Italy and
engineering consulting services, (ii) the establishment of ground operations and
distribution  agreements between Orion Atlantic and Telecom Italia, a subsidiary
of STET,  relating to Italy,  and the  granting to Telecom  Italia of  exclusive
marketing rights relating to Italy for a period ending December 1998 conditioned
upon  Telecom  Italia  achieving  certain  sales  quotas,  and  (iii)  canceling
exclusive ground operations and sales  representation  agreements  between Orion
Atlantic and STET (or its affiliates) relating to Eastern Europe.

   Orion  Atlantic   funded  the  STET  Redemption  by  selling  a  new  limited
partnership interest to Orion for $8 million (including $3.5 million in cash and
$4.5 million in 12% promissory  notes due through 1997).  In connection with the
STET  redemption,  Orion agreed to indemnify  Telecom  Italia for payments which
were made in July 1995 of $950,000  and which would be made in the future  under
its firm and contingent capacity agreements with Orion Atlantic and posted a $10
million  letter of credit to support such  indemnity.  The Company has accounted
for this transaction as an acquisition of a minority  interest and, as a result,
approximately  $3.1 million has been  allocated to the cost of the satellite and
related equipment.

   Other  Transactions  Involving  Limited  Partners -- Certain Limited Partners
were  also  subcontractors  under the  satellite  construction  contract.  Orion
Atlantic  also has  contracted  with Limited  Partners or their  affiliates  for
certain  consulting,  post-launch support services and other services related to
developing  the business.  Approximately  $5.0 million has been  incurred  under
these agreements, all of which was capitalized.

   During 1995,  Orion Atlantic  entered into  agreements  with certain  Limited
Partners (including the Company) under which the participating  Limited Partners
would  voluntarily  give up their  rights to receive  capacity  under their firm
capacity  agreements  through January 1996. The  participating  Limited Partners
would  continue to make  payments for such  capacity but would have the right to
receive  refunds from Orion Atlantic out of cash available after operating costs
and  payments  under the Credit  Facility.  Through  December  31,  1995,  Orion
Atlantic has received $14.1 million (excluding  payments from the Company) under
the firm capacity agreements subject to refund,  which amount is included in the
balance  sheet  caption  "Other  liabilities."  In  addition,  services  revenue
included  $5.7  million  in 1995  from  Limited  Partners  pursuant  to the firm
capacity commitments, not subject to refund.

4. COMMITMENTS AND CONTINGENCIES

   Obligations  with Respect to Orion  Atlantic -- Orion  presently  has certain
significant  obligations to Orion Atlantic and the Limited  Partners,  including
commitments  under  satellite  capacity   agreements  between  Orion  and  Orion
Atlantic,  under which Orion will be liable to pay Orion Atlantic  approximately
$2.5 million per year for seven years for satellite capacity and is contingently
liable for up to an  additional  $4.3  million per year for up to seven years if
Orion Atlantic  experiences cash flow deficits  commencing when Orion Atlantic's
first satellite begins commercial  operations;  and  reimbursement  (jointly and
severally with OrionSat) with respect to a $10 million letter of credit provided
by OrionSat to a limited partner,  which is secured by 259,515 shares of Orion's
common stock held in treasury and cash distributions that Orion and OrionSat may
receive with respect to their partnership interests in Orion Atlantic.

   Orion 1  satellite  -- In November  1995,  a portion of the Orion 1 satellite
experienced  an anomaly  that  resulted  in a  temporary  service  interruption,
lasting  approximately two hours, in the dedicated capacity serving the European
portion of Orion Atlantic's services. The nine affected transponders account for
a majority of Orion Atlantic's  present  revenues.  Full service to all affected
customers  was  restored  using  redundant  equipment  on the  satellite.  Orion
Atlantic  believes,  based on the data and the Telesat Report (issued by Telesat
Canada,  independent  engineering  consultants  dated November 14, 1995),  that,
because  the  redundant  component  is  functioning  fully  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.  Furthermore,  there has been no effect on Orion
Atlantic's ability to provide services to customers.  However, in the event that
the currently  operating component fails, Orion 1 would experience a significant
loss of usable capacity.  In such event,  while Orion Atlantic would be entitled
to insurance  proceeds of approximately  $50 million and could lease replacement
capacity  and function as a reseller  with respect to such  capacity (at reduced
levels of  profitability),  the loss of capacity  would have a material  adverse
effect on Orion and on Orion Atlantic.

   Orion 2 satellite -- In connection with the proposed  financing of Orion 2, a
subsidiary of Orion Atlantic entered into a satellite  construction contract for
Orion 2 with MMS Space  Systems,  subject to completion  of proposed  financing.
Depending  upon the timing and terms and conditions of the financing for Orion 2
and the then  satellite  design,  the Company  may seek to renew this  satellite
contract with MMS Space  Systems.  There can be no assurance that the terms of a
new satellite  contract will resemble  those of the satellite  contract with MMS
Space Systems. The Company expects to use Orion Atlantic's  Tracking,  Telemetry
and Control (TT&C) facility to control Orion 2 (although  authorizations will be
needed).

   Eutelsat Lease -- In January 1993, Orion Atlantic entered into a lease, which
expired in December  1994,  with one of its limited  partners  under which Orion
Atlantic  leased  one-half of a transponder  on a EUTELSAT  satellite for use in
providing private network services prior to the operational delivery of Orion 1.
The lease required quarterly payments of $481,000 of which $855,000 was deferred
by the limited  partner  until March 1995.  Rent under this lease  totaled  $1.9
million in 1994 and $1.8 million in 1993.

   Litigation  -- In October 1995,  Skydata  Corporation  ("Skydata"),  a former
contractor,  filed suit against Orion Atlantic,  Orion Satellite Corporation and
Orion,  in the United States  District Court for the Middle District of Florida,
claiming  that certain  Orion  Atlantic  operations  using frame relay  switches
infringe  a Skydata  patent.  Skydata's  suit  sought  damages  in excess of $10
million and asked that any damages  assessed be trebled.  On December  11, 1995,
the Orion  parties  filed a motion to dismiss the lawsuit on the grounds of lack
of jurisdiction and violation of a mandatory arbitration agreement. In addition,
on December 19, 1995, the Orion parties filed a Demand for  Arbitration  against
Skydata  with  the  American  Arbitration   Association  in  Atlanta,   Georgia,
requesting   damages  in  excess  of  $100,000   for  breach  of  contract   and
declarations,   among  other  things,  that  Orion  and  Orion  Atlantic  own  a
royalty-free license to the patent, that the patent is invalid and unenforceable
and that Orion and Orion Atlantic have not infringed on the patent. See Note 11.

   While Orion is party to  regulatory  proceedings  incident to the business of
Orion,  there  are no  other  material  legal  proceedings  pending  or,  to the
knowledge of management, threatened against Orion or its subsidiaries.

   Other -- Orion has entered  into  operating  leases,  principally  for office
space.  Rent expense was $735,000,  $668,000 and $661,000 during 1995, 1994, and
1993, respectively.

   Senior Notes  Payable to Banks -- In December  1991,  OrionSat,  on behalf of
Orion  Atlantic,  executed a credit  agreement  for up to $400 million of senior
debt from an international banking syndicate.  Amounts advanced under the credit
facility  are  secured  by the assets of Orion  Atlantic  and are due over seven
years in graduated  installments  beginning July 31, 1995. The credit  agreement
prohibits  the  extension  of credit by Orion  Atlantic to any  affiliate of the
partnership,  as defined.  Accordingly,  Orion  Atlantic may not loan or advance
funds to the Company or its  affiliates.  The credit  agreement  also  restricts
distributions  to the partners.  At December 31, 1995, none of Orion  Atlantic's
capital was  available  for  distribution.  The credit  facility has a number of
other  customary  covenants and  requirements,  including the Banks' approval of
significant  changes to the  construction  contract  and  increases  in budgeted
costs.  The Banks also have full  recourse to OrionSat as general  partner,  and

5. LONG-TERM DEBT-(Continued)


   Amounts outstanding under the credit facility bear interest at 1.75% over the
LIBOR (7.68% at December 31, 1995).  Orion Atlantic has entered into  agreements
with Chase Manhattan Bank, N.A.  (Chase) for interest rate hedging  arrangements
which  fixed  the  maximum  interest  rate  through  November  1995  at  11.54%.
Thereafter a self funding  interest rate cap agreement is in place relating to a
notional amount declining every six months from $150 million effective  November
30, 1995 to $15.6 million  effective March 31, 2001.  Under the terms of the cap
agreement,  when LIBOR  equals or exceeds 5.5% Orion  Atlantic  pays Chase a fee
equal to 3.3% per annum of the notional amount and receives a payment from Chase
in an amount equal to the  difference  between the actual LIBOR rate and 5.5% on
the notional  amount.  There was an  unrealized  loss as of December 31, 1995 of
approximately  $4.6 million relating to these  arrangements.  Commitment fees of
0.5% of the unused Credit Facility are payable semiannually.

   Note  Payable -- TT&C  Facility -- Orion  Atlantic  entered  into a financing
arrangement with General Electric  Capital  Corporation  ("GECC") to finance the
Tracking Telemetry and Control (TT&C) Facility. The TT&C arrangement calls for a
note  payable,  the  maximum  amount of which is $11 million of which up to $8.9
million is for payment to Lockheed  Martin under the  Satellite  Control  System
Contract,  with the remaining  balance available to be drawn to finance the cost
of launch  insurance  required  for the  benefit of GECC.  In June  1995,  Orion
Atlantic  accepted the TT&C Facility and Orion Atlantic  refinanced $9.3 million
from GECC as a seven-year  term loan,  payable  monthly.  Orion  Atlantic made a
mandatory  prepayment of $1 million in January 1996.  The interest rate is fixed
at a 13.5%.

   The TT&C debt is secured by the TT&C Facility,  the Satellite  Control System
Contract and Orion Atlantic's  leasehold interest in the TT&C Facility land. The
TT&C  financing  agreement  contains  similar  representations,  warranties  and
covenants to those in the senior notes.
   
   Satellite  incentive  obligation  -- The  obligations  relating to  satellite
performance (see Note 3) have been recorded at the present value  (discounted at
14%, the Company's estimated incremental borrowing rate for unsecured financing)
of the required payments  commencing at the maturity of the senior notes payable
to banks and  continuing  through  2006.  Under  the  terms of the  construction
contract,  payment of the  obligation  is delayed  until such time as payment is
permitted  under the senior notes  payable to banks.  

   Notes Payable -- STET -- In connection with the STET Redemption (see Note 3),
the Company  issued STET $8 million of  promissory  notes which bear interest at
12% per annum.  Payments are due as follows:  $2.5 million plus accrued interest
on December  31, 1996;  $3.5  million  plus  accrued  interest on the earlier of
December 31, 1997 or the  refinancing of the senior notes payable to banks;  and
the remaining $2.0 million in monthly  installments of $0.2 million plus accrued
interest beginning January 1997.

   Notes  Payable  --  Limited  Partners  -- In 1993,  Orion  Atlantic  received
commitments for Preferred  Participation  Units (PPUs)  aggregating $9.5 million
from  certain  Limited  Partners  (including  $1.5  million  from Orion  Network
Systems) for development of Orion Atlantic's network services business.

   Holders of PPUs earn  interest on aggregate  amounts drawn at the rate of 30%
per annum,  of which 6% is paid and the  remainder  accrued,  but not paid until
July 1, 1995, at which time interest and principal payments due are subordinated
to operating requirements and senior notes debt service but are payable prior to
distributions  to  Limited  Partners.  Principal  amounts  drawn are  payable on
February 1, 1999.  Principal  amounts may be prepaid without penalty on or after
January 1, 1996.

6. REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY

   The  Company has  authorized  1,000,000  shares of $0.01 par value  preferred
stock.

   Redeemable Preferred Stock

   In June 1994, Orion issued 11,500 shares of Series A 8% Cumulative Redeemable
Convertible  Preferred  Stock at  $1,000  per  share  and  granted  an option to
purchase an  additional  3,833 shares of similar  preferred  stock at $1,000 per
share. Dividends on preferred stock accrue at 8% per year and are payable as and
when declared.  Orion may redeem the preferred stock at the amount invested plus
accrued and unpaid dividends. Upon such a redemption, the preferred stockholders
would  receive a warrant  to  acquire at $8.50 per share the number of shares of
common stock into which the preferred stock was  convertible.  The 11,500 shares
issued are convertible  into 1,352,941 shares of common stock ($8.50 per share).
Upon  conversion  any accrued and unpaid  dividends  would be waived.  Orion may
require  conversion  of the  preferred  stock  beginning in June 1996 if certain
conditions are met.

   The preferred stock has a liquidation preference equal to the amount invested
plus accrued and unpaid dividends.  Preferred  stockholders are entitled to vote
on an  as-converted  basis and have the  right to put the stock to Orion  upon a
merger,  change of control or sale of substantially all assets at the greater of
liquidation  value or fair  value.  The put  expires  upon the  completion  of a
qualified  public equity  offering,  as defined.  If the preferred  stock is not
previously  redeemed or converted to common stock,  the  preferred  stockholders
also have the right to put the stock to Orion as follows:  33 1/3%  beginning in
June 1999; 66 2/3% beginning in June 2000; and 100% beginning in June 2001.

   After Orion issued  preferred  stock (along with warrants and options to make
an  additional  investment)  in June  1994,  the  Directors  and  affiliates  of
Directors who purchased  common stock in December 1993 and the  institutions and
other investors who purchased common stock in June 1994 each exercised its right
to  receive  preferred  stock  (along  with  warrants  and  options  to  make an
additional  investment) in exchange for the common stock previously acquired and
Orion  issued an  aggregate  of 3,000  shares of  Series A  Preferred  Stock and
related options for 1,000 shares to such persons and entities, of which 9 shares
of  preferred  stock were  converted  into  1,058  shares of common  stock.  The
remaining  2,991 shares  issued are  convertible  into 351,882  shares of common
stock and the preferred stock underlying the options are convertible into 98,039
shares of common stock.

   In June 1995, certain Directors, affiliates of Directors, and certain holders
of Series A Preferred  Stock  purchased 4,483 shares of Series B Preferred Stock
for approximately $4.5 million.  This purchase was pursuant to an option granted
in June 1995 to purchase $1 of preferred stock similar to the Series A Preferred
Stock for each $3 of Series A Preferred  Stock  purchased  in June 1994,  except
that such similar  preferred  stock would be convertible at any time with Common
Stock at a price  within a range of $10.20 to $17.00  per share of common  stock
based  upon when the  option is  exercised.  The  Series B  Preferred  Stock has
rights,  designations  and  preferences  substantially  similar  to those of the
Series A Preferred Stock, and is subject to similar  covenants,  except that the
Series B Preferred  Stock is convertible  into 439,510 shares of Common Stock at
an  initial  price  of  $10.20  per  share,  subject  to  certain  anti-dilution
adjustments,  and  purchases  of Series B Preferred  Stock did not result in the
purchaser receiving any rights to purchase additional preferred stock.

   Stockholders' Equity

   In December  1993,  178,097  shares of Common Stock were issued at $10.20 per
share to new and existing shareholders.

   In May 1994,  Orion issued  588,235 shares of common stock at $8.50 per share
to Space Systems Loral pursuant to a stock purchase agreement.

   In May 1994, 19,424 shares of common stock were issued at $10.20 per share to
new and existing shareholders.

6. REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY-(Continued)

   In June 1994,  Orion issued an aggregate of 174,844 shares of common stock to
a limited  number of  institutions  and other  investors at a purchase  price of
$8.50 per share.

   The December  1993 and June 1994 common  stock  purchases  were  subsequently
converted to redeemable preferred stock.

   Stock Options -- In 1987, Orion adopted a stock option plan. Under this plan,
as amended,  1,470,588  shares of common stock are  reserved  for issuance  upon
exercise of options granted.  Shares of common stock may be purchased under this
plan at prices not less than the fair market  value,  as determined by the Board
of Directors, on the date the option is granted. The Board of Directors also has
granted  nonqualified  options to purchase 53,341 shares of common stock outside
the plan described at prices ranging from $5.44 to $12.24 per share.

   Stock options outstanding at December 31:

   In November  1993,  options for 95,588 shares of common stock were granted to
key  executives  which may be  exercised  only upon the  achievement  of certain
business and financial objectives. In 1995 and 1994, these executives earned the
right to exercise 11,029 and 29,410 of these options based on the achievement of
such objectives.

   The options vest  annually  over a one to five-year  period.  All options are
exercisable  up to seven years from the date of grant.  There are  approximately
499,119 shares  available to be granted under the plan. As of December 31, 1995,
356,226 qualified and nonqualified options were exercisable.

   Stock Warrants -- Orion issued stock warrants to a financial  advisor in 1991
entitling the financial  advisor to purchase  43,049 shares of common stock at a
price of $11.56 a share.  Also,  in 1991,  as an  inducement to Chase to provide
partnership  bridge equity if required,  Orion issued stock  warrants  entitling
Chase to purchase up to 73,529 shares of common stock at $11.56 per share. These
warrants expire in 1996.

   Finally, as an inducement to two limited partners to incur satellite capacity
obligations  required by the senior debt lender,  Orion issued  warrants for the
purchase of an  aggregate  129,757  shares of common  stock at $11.56 per share.
These warrants expire in 1996. See Note 11.

   Warrants  have been  issued,  in  conjunction  with loans to Orion by certain
stockholders and members of executive  management  (since repaid or converted to
common  stock),  to acquire  483,823 shares of Orion's common stock at $11.56 to
$12.92 per share through 1997. The exercise price of these warrants was equal to
or above the fair value of the stock at the time of  issuance;  accordingly,  no
value was allocated to the warrants.  Total warrants outstanding were 553,768 at
December 31, 1995 and 735,769 at December 31, 1994 and 1993.

   The holders of  preferred  stock also hold  warrants  to  purchase  1,704,824
shares of common stock at the conversion  price of such preferred  stock.  These
warrants  do  not  become  exercisable  unless  Orion  exercises  its  right  to
repurchase the preferred stock at the liquidation value, plus accrued and unpaid
dividends.

6. REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY-(Continued)

   The Company has elected to  continue to follow  Accounting  Principles  Board
Opinion No. 25,  "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations  in  accounting  for its  employee  stock based award  programs,
because the alternative fair value accounting  provided for under FASB Statement
No. 123, "Accounting for Stock Based Compensation" which is effective for awards
after  January 1, 1996  requires  use of option  valuation  models that were not
developed  for use in valuing  employee  stock  options.  Under APB 25, when the
exercise  price of the employee  award equals the market price of the underlying
stock on the date of grant, as has been the case historically with the Company's
awards, no compensation expense is recognized.

7. INVESTMENT IN ASIA PACIFIC

   In January 1990,  Orion entered into an arrangement with Asia Pacific whereby
each  company  exchanged  into escrow  common  shares  having a market  value of
$500,000. In this exchange, Orion received 250,000 shares of Asia Pacific common
stock representing at that time an 11% ownership  interest,  for which it issued
51,061 shares of common stock at a value of $9.79 per share to Asia Pacific. The
assigned value of the Asia Pacific shares received of $500,000 was recorded as a
reduction  to  stockholders'  equity.  In 1992,  the Board of Directors of Orion
authorized the  acquisition of up to 100% of Asia Pacific's  outstanding  common
stock.  As a result of this new  agreement,  the January  1990  transaction  was
rescinded  and the  shares  held  in  escrow  were  returned  to the  respective
companies.  The acquisition of an 83% interest in Asia Pacific was finalized and
executed in  December  1992,  resulting  in the  exchange  of 289,147  shares of
Orion's  common stock for 2,089,392  shares of Asia Pacific  common  stock.  The
acquisition was accounted for as a purchase.
Asia Pacific is a development stage enterprise.

8. FAIR VALUES OF FINANCIAL INSTRUMENTS

   Other  than  amounts  due under the  senior  notes  payable  to banks,  Orion
believes  that the carrying  amount  reported in the balance  sheet of its other
financial assets and liabilities  approximates  their fair value. The fair value
of Orion  Atlantic's  senior  notes  payable to banks at  December  31,  1995 is
estimated to be $235.1 million based on the principal balance  outstanding,  net
of the estimated fair value of the interest rate modification  agreement,  which
approximates  an  implicit  loss of $4.6  million.  Credit  risk  exists  if the
counterparty  is not able to make the  required  payments  to Orion  under these
agreements. Orion believes the risk to be remote.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

11. SUBSEQUENT EVENTS (UNAUDITED)

   In July  1996,  Orion  entered  into an  Exchange  Agreement  (the  "Exchange
Agreement")  with the  Limited  Partners  that  hold 58 1/3% of the  partnership
interests  in Orion  Atlantic.  Pursuant to the Exchange  Agreement,  Orion will
acquire  all of  the  interests  held  by  the  Limited  Partners,  as  well  as
approximately $38 million of Orion Atlantic  indebtedness to Limited Partners in
exchange for a newly issued series of redeemable  convertible preferred stock in
Orion and the  release of certain  credit  support  obligations  of the  Limited
Partners.  The  Exchange  Agreement  is  conditioned  upon a  number  of  events
including,  among other things,  shareholder approval, the British Aerospace and
Matra Marconi  Space  debenture  investments,  the  acquisition  of the minority
interest of Asia Pacific held by British  Aerospace,  and the refinancing of the
Orion 1 Credit Facility, all as described below.

   Orion  intends  to enter  into an  agreement  with an  affiliate  of  British
Aerospace to acquire their 17% outstanding minority interest in Asia Pacific for
approximately 86,000 shares of Orion Common Stock.
   
   Orion has entered into a Memorandum of Agreement, effective December 6, 1996,
for procurement of Orion 2 spacecraft with Matra Marconi Space with an aggregate
contract value of $200.8 million,  excluding launch  insurance.  On December 13,
1996, Orion entered into an Authorization to Proceed Agreement with Hughes Space
and Communications  International for the procurement of Orion 3 spacecraft with
an aggregate contract value, subject to execution of a definitive agreement,  of
$208 million,  excluding launch insurance.  Construction of Orion 3 commenced in
mid-December 1996.    
   
   The Company intends to file a Registration  Statement with the Securities and
Exchange  Commission  pursuant  to  which  the  Company  will  offer  to sell an
aggregate  of $381 million of Units  consisting  of Senior  Notes,  due 2007 and
warrants to purchase  common  stock,  and an  aggregate of $219 million of Units
consisting  of Senior  Discount  Notes due 2007 and warrants to purchase  common
stock (the "Offering").  The proceeds from this offering are intended to be used
primarily  to  refinance  the  Orion 1 Credit  Facility.  Concurrently  with the
Offering,  British  Aerospace and Matra Marconi Space have committed to purchase
$50 million  and $10  million of  convertible  junior  subordinated  debentures,
respectively.  Such  debentures  are expected to bear  interest at 8.75% payable
semiannually  in Orion  common  stock  (valued at up to $14.00 per share)  until
maturity in 2012. The Offering is conditioned on  consummation  of the Exchange,
repayment of the Orion 1 Credit  Facility  with proceeds of the Offering and the
British Aerospace and Matra Marconi Space debenture investments; the Exchange is
conditioned on, among other things,  the Orion 2 Satellite  Contract,  which has
been entered  into,  and approval of the Orion  stockholders,  expected to occur
prior to the  pricing  of the  Offering;  and the  British  Aerospace  debenture
investment is  conditioned  on Orion's  acquisition  of the  remaining  minority
interest in Asia Pacific, which has occurred or is in the process of occurring.
    
   In November 1996, Orion entered into a contract with DACOM Corp. ("DACOM"), a
Korean  communications  company,  under which  DACOM will lease eight  dedicated
transponders on Orion 3 for 13 years, in return for  approximately  $89 million,
which is payable over a period from December  1996 through six months  following
the lease commencement date for the transponders (which is scheduled to occur by
January  1999).  DACOM is to  deposit  funds  with  Orion in  accordance  with a
milestone schedule. It has the right to terminate the contract at any time prior
to March 31, 1997, upon which  termination Orion would be entitled to retain all
deposited  funds.  Prior to  launch,  payments  will be held in  escrow  and are
subject to refund pending the successful  launch and  commencement of commercial
operation  of Orion 3. In  November  1996,  Orion  granted an option to Dacom to
purchase  50,000  shares of common  stock at a price of $14.00  per  share.  The
warrant is  exercisable  for a six-month  period  beginning six months after the
commencement date, as defined in the Joint Investment Agreement,  and ending one
year after  commencement date and will terminate at that time or at any time the
Joint Investment Agreement is terminated.

   In January 1997, Orion issued an aggregate of  approximately 86,500 shares of
Common Stock to British Aerospace,  one of the Company's principal  stockholders
which has a  representative  on the

Company's  Board of  Directors.  Such issuance was pursuant to the exercise of a
warrant  granted in December  1991 in  connection  with the  formation  of Orion
Atlantic.

   Litigation. In connection with the Skydata suit discussed in Note 4, on March
5, 1996,  the court granted the  Company's  motion to dismiss the lawsuit on the
basis that Skydata's  claims are subject to  arbitration.  Skydata  appealed the
dismissal to the United States Court of Appeals to the Federal Circuit.  Skydata
also filed a counterclaim in the arbitration  proceedings  asserting a claim for
$2 million  damages as a result of the conduct of Orion and its  affiliates.  On
May 15, 1996, the arbitrator  granted the Orion parties'  request for an initial
hearing on claims relating to the Orion parties' rights to the patent, including
the co-ownership  claim and other contractual  claims.  This initial hearing was
scheduled to take place in November 1996. On November 9, 1996, Orion and Skydata
executed a letter to settle in full the pending  litigation and arbitration.  As
part of the  settlement,  the  parties  are to release all claims by either side
relating in any way to the patent and/or the pending litigation and arbitration.
In  addition,  Skydata is to grant Orion (and its  affiliates)  an  unrestricted
paid-up  license to make,  have made,  use or sell products or methods under the
patent and all other corresponding continuation and reissue patents. Orion is to
pay Skydata  $437,000 over a period of two years as part of the settlement.  The
parties  are in the  process of  documenting  the terms of the  settlement  in a
formal settlement agreement.

   Orion. Orion's Certificate of Incorporation  provides that its directors will
not be liable for monetary  damages for breach of the directors'  fiduciary duty
of care to the Company and its  stockholders.  This provision in the Certificate
of  Incorporation  does  not  eliminate  the duty of  care,  and in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary  relief would remain  available  under  Delaware law. In accordance
with  the  requirements  of  Delaware  law,  as  amended,   the  Certificate  of
Incorporation  provide that the  Company=s  directors  would  remain  subject to
liability  for  monetary  damages (i) for any breach of their duty of loyalty to

or officer of Orion (or is or was  serving at the request of Orion as a director
or officer of another  enterprise),  against  expenses,  liabilities  and losses
(including attorney's fees), judgments,  fines and amounts paid or to be paid in
settlement  actually and reasonably  incurred by such person in connection  with
such action,  suit or proceeding if such person acted in good faith and a manner
such person reasonably believed to be in or not opposed to the best interests of
Orion, and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful. Such indemnification shall not
be made in respect of any claim,  issue or matter as to which such person  shall
have been  adjudged to be liable to Orion  unless (and only to the extent  that)

action,  suit or  proceeding  by reason of the fact that such person is or was a
director or officer of Old ONSI (or is or was serving at the request of Old ONSI
as a  director,  officer,  employee  or agent of  another  enterprise),  against

and amounts paid or to be paid in settlement actually and reasonably incurred by
such person in connection with such action, suit or proceeding.

   OrionSat. OrionSat's Certificate of Incorporation provides that its directors
will not be liable for monetary  damages for breach of the directors'  fiduciary
duty of care to OrionSat and its stockholders. This provision in the Certificate
of  Incorporation  does  not  eliminate  the duty of  care,  and in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary  relief would remain  available  under  Delaware law. In accordance
with  the  requirements  of  Delaware  law,  as  amended,   the  Certificate  of

liability  for  monetary  damages (i) for any breach of their duty of loyalty to

or agent of OrionSat (or is or was serving any other  enterprise  at the request
of OrionSat),  against expenses,  liabilities and losses  (including  attorney's
fees),  judgments,  fines and amounts paid or to be paid in settlement  actually
and reasonably  incurred by such person in connection with such action,  suit or
proceeding.

   OrionNet Finance Corporation.  OrionNet Finance Corporation's  Certificate of
Incorporation  provides  that its  directors  will not be  liable  for  monetary
damages for breach of the directors'  fiduciary duty of care to OrionNet Finance
Corporation  and  its  stockholders.   This  provision  in  the  Certificate  of
Incorporation   does  not  eliminate  the  duty  of  care,  and  in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary  relief would remain  available  under  Delaware law. In accordance
with  the  requirements  of  Delaware  law,  as  amended,   the  Certificate  of

omissions  not in good  faith or  involving  intentional  misconduct  or knowing

liabilities and losses (including attorney's fees), judgments, fines and amounts
paid or to be paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding.

   Asia Pacific Space and Communications,  Ltd. ("APSC").  APSC's Certificate of
Incorporation  provides that the personal  liability of its  directors  shall be
eliminated  to the fullest  extent  provided by Section 7 of  Subsection  (b) of
Section 102 of the Delaware Code.  This paragraph  allows for the elimination of
all personal  liability,  provided  that  liability  shall not be  eliminated or

Incorporation   does  not  eliminate  the  duty  of  care,  and  in  appropriate

(including attorney's fees), judgments,  fines and amounts paid or to be paid in
settlement  actually and reasonably  incurred by such person in connection  with
such action,  suit or proceeding if such person acted in good faith and a manner
such person reasonably believed to be in or not opposed to the best interests of
APSC, and, with respect to any criminal action or proceeding,  had no reasonable
cause to believe his or her conduct was unlawful. Such indemnification shall not
be made in respect of any claim,  issue or matter as to which such person  shall
have been adjudged to be liable to APSC unless (and only to the extent that) the
Delaware Court of Chancery or the court in which such action or suit was brought
determines that, in view of all circumstances of the case, such person is fairly
and reasonably entitled to indemnity.

   Orion  Asia  Pacific.  Orion  Asia  Pacific's  Certificate  of  Incorporation
provides that its directors  will not be liable for monetary  damages for breach
of the  directors'  fiduciary  duty  of  care  to  Orion  Asia  Pacific  and its
stockholders.  This  provision  in the  Certificate  of  Incorporation  does not
eliminate the duty of care, and in appropriate  circumstances equitable remedies

available  under Delaware law. In accordance  with the  requirements of Delaware
law, as amended,  the  Certificate  of  Incorporation  provides  that Orion Asia

and losses (including attorney's fees), judgments,  fines and amounts paid or to

connection with such action, suit or proceeding.

   OrionNet. OrionNet's Certificate of Incorporation provides that its directors
will not be liable for monetary  damages for breach of the directors'  fiduciary
duty of care to OrionNet and its stockholders. This provision in the Certificate
of  Incorporation  does  not  eliminate  the duty of  care,  and in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary relief would

                                      II-3

<PAGE>

remain  available  under Delaware law. In accordance  with the  requirements  of
Delaware  law,  as amended,  the  Certificate  of  Incorporation  provides  that
OrionNet's  directors would remain subject to liability for monetary damages (i)
for any breach of their duty of loyalty to the corporation or its  shareholders,
(ii) for acts or omissions not in good faith or involving intentional misconduct
or knowing  violation of law,  (iii) under  Section 174 of the Delaware Code for
approval of an unlawful dividend or an unlawful stock purchase or redemption and

environmental laws.

   OrionNet's  Bylaws  provide  that,  except as  expressly  prohibited  by law,
OrionNet  shall  indemnify any person who was or is a party (or threatened to be

or agent of OrionNet (or is or was serving any other  enterprise  at the request
of OrionNet),  against expenses,  liabilities and losses  (including  attorney's
fees),  judgments,  fines and amounts paid or to be paid in settlement  actually
and reasonably  incurred by such person in connection with such action,  suit or
proceeding.

   Orion Atlantic  Europe,  Inc. Orion Atlantic  Europe,  Inc.'s  Certificate of
Incorporation  provides  that its  directors  will not be  liable  for  monetary
damages for breach of the  directors'  fiduciary  duty of care to Orion Atlantic
Europe,  Inc.  and  its  stockholders.  This  provision  in the  Certificate  of
Incorporation   does  not  eliminate  the  duty  of  care,  and  in  appropriate
circumstances  equitable  remedies  such as an  injunction  or  other  forms  of
non-monetary  relief would remain  available  under  Delaware law. In accordance
with  the  requirements  of  Delaware  law,  as  amended,   the  Certificate  of
Incorporation provides that Orion Atlantic Europe, Inc.'s directors would remain
subject to liability  for  monetary  damages (i) for any breach of their duty of
loyalty to the corporation or its  shareholders,  (ii) for acts or omissions not
in good faith or involving  intentional  misconduct or knowing violation of law,
(iii)  under  Section  174 of the  Delaware  Code for  approval  of an  unlawful
dividend  or  an  unlawful  stock  purchase  or  redemption  and  (iv)  for  any
transaction from which the director derived an improper personal  benefit.  This
provision  also does not affect a  director's  responsibilities  under any other
laws,  such as the  federal  securities  laws or state or federal  environmental
laws.

   Orion Atlantic  Europe,  Inc.'s  Certificate of  Incorporation  also provides
that, except as expressly  prohibited by law, Orion Atlantic Europe,  Inc. shall
indemnify any person who was or is a party (or threatened to be made a party) to
any threatened, pending or completed action, suit or proceeding by reason of the
fact that such person is or was a director or officer of Orion Atlantic  Europe,
Inc. (or is or was serving at the request of Orion  Atlantic  Europe,  Inc. as a
director or officer of another  enterprise),  against expenses,  liabilities and
losses (including attorney's fees),  judgments,  fines and amounts paid or to be
paid in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding.

   Section 145 of the Delaware Code empowers a  corporation  incorporated  under
that statute to indemnify its directors,  officers, employees and agents and its
former  directors,  officers,  employees  and agents and those who serve in such
capacities with another  enterprise at its request against expenses,  as well as
judgments,  fines  and  settlements  in  nonderivative  lawsuits,  actually  and
reasonably  incurred by them in connection with the defense of any action,  suit
or  proceeding  in which  they or any of them  were or are made  parties  or are
threatened  to be made  parties by reason of their  serving or having  served in
such  capacity.  The power to  indemnify  shall only exist  where such  officer,
director,  employee or agent has acted in good faith and in a manner such person
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation  and,  in the case of a criminal  action,  where such  person had no
reasonable cause to believe his conduct was unlawful.  However,  in an action or
suit by or in the right of the  corporation,  unless a court shall  determine to
the contrary,  where such a person has been adjudged liable to the  corporation,
the corporation shall have no power of  indemnification.  Indemnity is mandatory
to the  extent  a  claim,  issue  or  matter  has  been  successfully  defended.
Indemnification  is not  deemed  exclusive  of any other  rights to which  those
indemnified may be entitled, under any by-law,  agreement,  vote of stockholders
or otherwise. A Delaware corporation also has the power to purchase and maintain
insurance on behalf of the persons it has the power to indemnify, whether or not
indemnity against such liability would be allowed under the statute.

   International  Private Satellite Partners,  L.P. ("IPSP").  The Third Amended
and Restated Agreement of Limited Partnership of International Private Satellite
Partners,  L.P.  (the "IPSP  Partnership  Agreement")  provides that neither the
general  partner  (OrionSat)  nor  any of its  affiliates  ,  nor  any of  their
respective partners, officers,  directors,  employees or agents, shall be liable
to IPSP or its limited partners for any losses sustained or liabilities incurred
as a result of any act or omission,  so long as such conduct does not constitute
bad  faith,  fraud,  gross  negligence,  willful  misconduct  or  breach  of any
fiduciary duty.

   The IPSP  Partnership  Agreement  also  provides  that,  except as  expressly
prohibited by law,  IPSP shall  indemnify  OrionSat,  its  affiliates  and their
respective partners, officers, directors,  employees and agents from any and all
expenses,  liabilities and losses (including attorney's fees), judgments,  fines
and amounts paid or to be paid in settlement  arising from any claims,  demands,
actions,  suits or proceedings,  arising out of or incidental to the business or
activities relating to IPSP.

   Insofar as indemnification  for liabilities  arising under the Securities Act
of 1933,  as amended (the  "Securities  Act"),  may be  permitted to  directors,
officers and controlling persons of Orion pursuant to the foregoing provision or
otherwise,  Orion has been advised  that, in the opinion of the  Securities  and
Exchange Commission,  such indemnification is against public policy as expressed
in the Securities Act and therefore unenforceable. In the event that a claim for
indemnification   against  such  liabilities  is  asserted  by  such  person  in
connection  with the offering of the  Securities  (other than for the payment by
the  corporation  of  expenses  incurred  or  paid  by a  director,  officer  or
controlling  person of the corporation in the successful  defense of any action,
suit or proceeding),  the either  corporation will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of appropriate  jurisdiction the question of whether such  indemnification by it
is against public policy as expressed in the Securities Act and will be governed
by the final adjudication of the issue.

   Orion has insurance policies which will insure directors and officers against
damages from actions and claims  incurred in the course of their duties and will
insure the corporations  against expenses incurred in defending lawsuits arising
from certain alleged acts of the directors and officers.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

   During  the past three  years,  Orion  (which  completed  an  initial  public
offering in August 1995) issued the following unregistered securities,  adjusted
to reflect a  1.00-for-1.36  reverse  stock  split  effected  in July  1995.  No
underwriting  discounts or commissions  were paid in connection with any of such
transactions,  although a fee of $250,000  was paid to Salomon  Brothers Inc for
serving as a financial  advisor to Orion in connection with Orion's 1994 private
placement.  There  was  no  public  offering  in  such  transactions,   and  the
transactions  were exempt from the  registration  requirements of the Securities
Act by reason of Sections  4(2) and 3(b) thereof,  and  Regulation D promulgated
thereunder.  In each instance,  the shares of Common Stock,  shares of Preferred
Stock or warrants of Orion were issued to a limited group of purchasers, each of
which had access to and/or  was  furnished  information  concerning  Orion.  The
purchasers  acquired the securities  for investment  only and not with a view to
the distribution  thereof, and each of the certificates  representing the shares
of Common  Stock and  Preferred  Stock of Orion  issued to such  purchasers  was
stamped with a legend restricting the transfer of the shares of Common Stock and
Preferred Stock representing thereby.

Common Stock

   In December 1993, Orion issued an aggregate of 178,097 shares of Common Stock
as part of a private  placement of its Common Stock to certain of its  Directors
and affiliates of those  Directors at a purchase price of $10.20 per share.  The
terms of such issuance  permitted  the  purchasers to receive the benefit of any
lower  price at which  Common  Stock  subsequently  was  issued  in the  private
placement or to receive any other  security  subsequently  issued in the private
placement. In June 1994, when Orion issued shares of Common Stock as part of the
private  placement of its Common Stock to a limited number of  institutions  and
other  investors  (including  64,705  shares to  affiliates  of  Directors) at a
purchase price of $8.50 per share, Orion issued 100,326 additional shares to the
Directors and  affiliates  of Directors  who purchased  Common Stock in December
1993. In addition, after Orion issued Series A

                                      II-5

<PAGE>


Preferred  Stock  (along  with  warrants  and  options  to  make  an  additional
investment)  to CIBC,  Fleet  and  Chisholm  in June  1994,  the  Directors  and
affiliates  of  Directors  who  purchased  Common  Stock in  December  1993 each
exercised  his or its right to receive  Series A  Preferred  Stock  (along  with
warrants  and options to make an  additional  investment)  in  exchange  for the
Common Stock previously acquired, and Orion issued an aggregate of $3,000,000 of
Series A Preferred Stock to such persons and entities.

   In May 1994, Orion entered into an agreement with SS/L whereby SS/L agreed to
purchase  588,235  shares of Common  Stock for an  aggregate  purchase  price of
$5,000,000.  The  agreement  with SS/L includes a possible  sale,  under certain
circumstances,  of an additional 588,235 shares of Common Stock for an aggregate
purchase  price of  $5,000,000.  SS/L has the right to  require  the  Company to
repurchase  the 588,235  shares from SS/L if Orion  selects a company other than
SS/L as the prime  contractor in a contract for  construction  of a satellite to
serve the Asia Pacific region.  SS/L has the right, during the three year period
after the sale of the initial shares of Common Stock,  to receive more shares of
Common  Stock;  under certain  circumstances,  if Orion issues Common Stock or a
security  convertible  into or exchangeable for Common Stock for a price of less
than $8.50 per share.

   In June 1994,  Orion issued an aggregate of 174,844 shares of Common Stock as
part  of a  private  placement  of its  Common  Stock  to a  limited  number  of
institutions  and other  investors at a purchase  price of $8.50 per share.  The
terms of such issuance  permitted  the  purchasers to receive the benefit of any
lower  price at which  Common  Stock  subsequently  was  issued  in the  private
placement or to receive any other  security  subsequently  issued in the private
placement.  When Orion issued Series A Preferred  Stock (along with warrants and
options to make an additional  investment)  to CIBC,  Fleet and Chisholm in June
1994, the  institutions  and other investors who purchased  Common Stock in June
1994 each exercised  his, her or its right to receive  Series A Preferred  Stock
(along with warrants and options to make an additional  investment)  in exchange
for the Common  Stock  previously  acquired,  and Orion  issued an  aggregate of
$3,000,000 of Series A Preferred Stock to such persons and entities.

   In March 1995 (but  pursuant  to a contract  signed in  January  1994)  Orion
issued an aggregate  of 2,941  shares of Common  Stock to a  recruiting  firm as
compensation for work performed for Orion.

   In January 1997, Orion issued an aggregate of approximately  86,500 shares of
Common Stock to British Aerospace,  one of the Company's principal  stockholders
which has a  representative  on the Company's Board of Directors.  Such issuance
was pursuant to the exercise of a warrant granted in December 1991 in connection
with the formation of Orion Atlantic.

   Orion has, from time to time, issued Common Stock upon conversion of Series A
and Series B Preferred Stock.

Preferred Stock

   In June 1994, CIBC, Fleet and Chisholm purchased $11.5 million in Series A 8%
Cumulative Redeemable  Convertible Preferred Stock, which shares are convertible
into  shares of  Common  Stock at an  exercise  price of $8.50  per  share.  See
"Description  of Capital Stock -- Preferred  Stock." CIBC,  Fleet,  and Chisholm
also were  granted  the right to invest an  additional  $3.8  million in similar
preferred stock,  except that such similar  preferred stock would be convertible
at any time into  Common  Stock at a price  within a range from $10.20 to $17.00
per share of Common  Stock based upon when the option is  exercised  and certain
other  factors.  CIBC,  Fleet,  and  Chisholm  also were  granted a  contractual
"preemptive"  right to purchase a pro rata portion of any equity securities sold
by Orion in the  future on the same  terms  and  conditions  as sold to  others,
subject to  certain  exceptions  for  securities  sold or granted to  employees,
certain small offerings, and existing rights to acquire equity securities. CIBC,
Fleet and Chisholm also were granted certain warrants (issued  concurrently with
the Series A Preferred  Stock) to purchase Common Stock at the conversion  price
of such  Series A Preferred  Stock.  These  warrants  do not become  exercisable
unless Orion  exercise its right to repurchase  the Series A Preferred  Stock at
the liquidation  value (plus accrued and unpaid  dividends).  In connection with
the transaction,  CIBC and Fleet each were granted the right to elect one member
of Orion's Board of Directors.

   After Orion issued Series A Preferred  Stock (along with warrants and options
to make an additional  investment) to CIBC, Fleet and Chisholm in June 1994, the
Directors and  affiliates  of Directors  who purchased  Common Stock in December
1993 and the institutions and other investors who pur-

                                      II-6

chased Common Stock in June 1994 each exercised his, her or its right to receive
Series A Preferred  Stock (along with warrants and options to make an additional
investment)  in exchange  for the Common  Stock  previously  acquired  and Orion
issued an aggregate of $3.0 million of Series A Preferred  Stock to such persons
and entities.

   In June 1995,  CIBC and certain  Directors  and  affiliates  of Directors who
purchased  Series A Preferred  Stock in June 1994 purchased  approximately  $4.2
million in Series B Preferred  Stock of Orion.  This purchase was pursuant to an
option  granted in June 1994 to purchase $1 of  preferred  stock  similar to the
Series A Preferred  Stock for each $3 of Series A Preferred  Stock  purchased in
June 1994,  except that such similar preferred stock would be convertible at any
time into Common Stock at a price within a range from $10.20 to $17.00 per share
of Common Stock based upon when the option is exercised.  The Series B Preferred
Stock has rights, designations and preferences substantially similar to those of
the Series A Preferred Stock discussed above, except that the Series B Preferred
Stock is convertible  into Common Stock at an initial price of $10.20 per share,
subject to certain anti-dilution adjustments, and purchase of Series B Preferred
Stock  did not  result  in the  purchasers  receiving  any  rights  to  purchase
additional  preferred stock. The purchasers of the Series B Preferred Stock also
were granted certain warrants (issued  concurrently with the Preferred Stock) to
purchase Common Stock at the conversion  price of such Series B Preferred Stock.
These  warrants do not become  exercisable  unless Orion  exercises its right to
repurchase the Series B Preferred Stock at the  liquidation  value (plus accrued
and unpaid dividends).

Warrants

   In May 1994,  in connection  with the sale of Common Stock to SS/L  discussed
under "Common Stock" above,  Orion granted an option to SS/L to purchase 588,235
shares of Common  Stock at a price of $8.50 per share  prior to January 1, 1995,
which option has expired.

   In June  1994,  in  connection  with the sale of  Series  A  Preferred  Stock
discussed under "Preferred Stock" above,  Orion granted an option to the holders
of Series A  Preferred  Stock to invest an  additional  $4.8  million in similar
preferred  stock (except that such similar  preferred stock would be convertible
at any time into Common Stock at a price based upon when the option is exercised
within a range from $10.20 to $17.00 per share of Common Stock). The purchase of
Series B Preferred  Stock in June 1995  represented  an exercise of the right to
invest approximately $4.5 million of this amount. Orion also granted the holders
of Preferred  Stock certain  warrants to purchase Common Stock at the conversion
price of such Preferred Stock.  These warrants do not become  exercisable unless
Orion  exercises its right to repurchase the Preferred  Stock at the liquidation
value (plus accrued and unpaid dividends).

   In December 1996,  Orion issued an option to DACOM to purchase  50,000 shares
of Common Stock at a price of $14.00 per share. The warrant is exercisable for a
six (6) month period  beginning six (6) months after the  commencement  date, as
defined  in the Joint  Investment  Agreement,  and ending one (1) year after the
commencement  date  and will  terminate  at that  time or at any time the  Joint
Investment Agreement between DACOM and Orion is terminated.

ITEM 17. UNDERTAKINGS.

   The undersigned Registrants hereby undertake:

      (a)(1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement;

               (i) To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

               (ii) To reflect  in the  prospectus  any facts or events  arising
          after the effective  date of the  Registration  Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the  Registration  Statement.  Notwithstanding  the foregoing,  any
          increase  or decrease  in volume of  securities  offered (if the total
          dollar  value of  securities  offered  would not exceed that which was
          registered)  and  any  deviation  from  the  low  or  high  and of the
          estimated  maximum  offering  range  may be  reflected  in the form of
          prospectus  filed with the  Commission  pursuant to Rule 424(b) if, in
          the aggregate,  the changes in volume and price represent no more than
          a 20 percent change in the maximum aggregate  offering price set forth
          in the  "Calculation  of  Registration  Fee"  table  in the  effective
          registration statement.

               (iii) To include any  material  information  with  respect to the
          plan of  distribution  not  previously  disclosed in the  Registration
          Statement  or  any  material   change  to  such   information  in  the
          Registration Statement;

         (2) That,  for the  purpose  of  determining  any  liability  under the
    Securities Act of 1933, each such  post-effective  amendment shall be deemed
    to be a new  registration  statement  relating  to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
    any  of  the  securities   being  registered  which  remain  unsold  at  the
    termination of the offering.

    (b) That,  for purposes of  determining  any liability  under the Securities
  Act, the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in the form of
  prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
  under the  Securities  Act  shall be  deemed  to be part of this  Registration
  Statement as of the time it was declared effective; and

    (c) That, for the purpose of determining  any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall be
  deemed to be a new registration  statement  relating to the securities offered
  therein,  and the offering of such  securities at that time shall be deemed to
  be the initial bona fide offering thereof.

Insofar as indemnification  for liabilities arising under the Securities Act may
be permitted to directors,  officers and controlling  persons of the Registrants
pursuant to the foregoing  provisions,  or otherwise,  the Registrants have been
advised that in the opinion of the Securities and Exchange Commission such

                                      II-13

<PAGE>


indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such liabilities  (other than the payment by the Registrants of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered,  the  Registrants  will,  unless in the opinion of their counsel the
matter  has  been  settled  by  controlling  precedent,  submit  to a  court  of
appropriate  jurisdiction  the question  whether such  indemnification  by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

              upon exercise of the Warrants (the "Warrant Shares") to be sold by
              the Company and arrangements in connection therewith.

         In our  examination  of the  aforesaid  documents,  we have assumed the
genuineness  of all  signatures,  the legal  capacity  of natural  persons,  the
authenticity,  accuracy and  completeness of all documents  submitted to us, and
the conformity with the original  documents of all documents  submitted to us as
certified, telecopied, photostatic, or reproduced copies. This opinion letter is
given, and all statements herein are made, in the context of the foregoing.

         This opinion letter is based as to matters of law solely on the General
Corporation  Law of the State of Delaware,  and the contract law of the State of
New  York.  We  express  no  opinion  herein  as to any  other  laws,  statutes,
regulations or ordinances.

         Based  upon,  subject to and  limited by the  foregoing,  we are of the
opinion that following (i)  effectiveness  of the Registration  Statement,  (ii)
final  action of the Board of  Directors  of the  Company  (or a duly  appointed
pricing committee  thereof)  approving the interest rate and other pricing terms
of the Units,  the Notes and the  Warrants,  (iii) due execution and delivery by
the Company of the Underwriting Agreement, the Senior Note Indenture, the Senior
Discount Note Indenture and the Warrant Agreement, (iv) sale and issuance of the
Units  pursuant  to the terms of the  Underwriting  Agreement,  issuance  of the
Senior  Notes  pursuant  to the Senior  Note  Indenture,  issuance of the Senior
Discount  Notes  pursuant to the Senior  Discount Note Indenture and issuance of
the Warrants pursuant to the Warrant Agreement and (v) receipt by the Company of
the  consideration  for the Units  specified in the  resolutions of the Board of
Directors:

       (1) the  Units,  the  Notes  and the  Warrants  will  constitute  binding
           obligations  of  the  Company  enforceable  against  the  Company  in
           accordance with their terms,  except as may be limited by bankruptcy,
           insolvency,  reorganization,   moratorium  or  other  laws  affecting
           creditors'  rights  (including,  without  limitation,  the  effect of
           statutory and other law regarding fraudulent conveyances,  fraudulent
           transfers and  preferential  transfers)  and as may be limited by the
           exercise of judicial  discretion and the application of principles of
           equity,  including,  without limitation,  requirements of good faith,
           fair dealing,  conscionability and materiality (regardless of whether
           the Units,  the Notes and the Warrants are considered in a proceeding
           in

<PAGE>


           equity or at law); provided, however, that we express no opinion with
           respect to Section 11.5 of the Warrant  Agreement as  incorporated in
           the Warrants and made a part thereof; and



       (2) the Warrant Shares have been duly authorized by the Company and, when
           issued and delivered upon exercise of the Warrants in accordance with
           the terms of the Warrant  Agreement  as in effect on the date hereof,
           will be validly issued, fully paid and non-assessable.

         The opinion  expressed in paragraph  (1) above shall be  understood  to
mean only that if (i) there is a default in performance of an obligation, (ii) a
failure to pay or other damage can be shown and (iii) the  defaulting  party can
be brought  into a court which will hear the case and apply the  governing  law,
then,  subject to the availability of defenses,  and to the exceptions set forth
above, the court will provide a money damage (or perhaps  injunctive or specific
performance) remedy.



         We assume no  obligation  to advise you of any changes in the foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared solely for your use in connection  with the filing of the  Registration
Statement on the date of this  opinion  letter and should not be quoted in whole
or in part or  otherwise  be  referred  to, nor filed with or  furnished  to any
governmental agency or other person or entity, without the prior written consent
of this firm.

         We hereby  consent to the filing of this opinion  letter as Exhibit 5.1
to the  Registration  Statement  and to the  reference  to this  firm  under the
caption  "Legal   Matters"  in  the  prospectus   constituting  a  part  of  the

      least ten (10) days but no more than  forty-five  (45) days in  advance of
      the date when such  payment is scheduled to be made by Customer to Hughes.
      Failure by Hughes to provide an  invoice  for any given  Progress  Payment
      will not excuse Customer's  payment obligation or change the due date with

      having to make such payment (except the Balloon Payment) that Hughes is on
      schedule  to  Deliver  the  Satellite  in  accordance  with  the  Delivery
      Schedule. Such certification shall be in the form attached hereto as Annex
      A.

4.8   Subject to Subparagraphs (A) and (B) below, Customer shall pay Hughes each
      Progress  Payment  on or before the date  specified  in Exhibit F (Payment
      Plan);  provided,  however,  where the specified  date causes a payment to

      Business Day.

      A.    If Hughes makes the  certification  required by Paragraph  4.7 as to
            any  Progress  Payment  due after the Balloon  Payment but  Customer
            disputes it, Customer shall pay such Progress Payment into an escrow
            account in accordance with Paragraph 4.9 and the disposition of such
            escrowed  amount  shall be governed  by  Paragraph  4.9.  During the
            period  any  Progress  Payment is held in  escrow,  Hughes  shall be
            obligated to continue performance, but Hughes shall not be obligated
            to proceed to Intentional Ignition until the dispute is resolved and
            any amounts  ultimately  determined to be due Hughes are released to
            Hughes from escrow.

            $6,000,000))  of delay (as  certified by Hughes) with respect to the
            delivery of the  Satellite,  such payments to be repaid to Hughes to
            the extent Hughes subsequently  certifies a reduced (or no) delay in
            delivery of the Satellite. Under this subparagraph (B), Hughes shall
            not be  obligated  to proceed  to  Intentional  Ignition  unless all
            required Progress Payments (less any applicable  liquidated damages)
            are current.

4.9   No dispute  with  respect to the payment of any amount  under the Contract
      shall  relieve  the  disputing  Party of its  obligation  to pay all other
      amounts due and owing under the  Contract.  All disputed  amounts,  unless
      otherwise   specified   in  the   Contract,   shall   be   paid   into  an
      interest-bearing  escrow account (to be specified in writing by Hughes) on
      or before the applicable due date. After the dispute is settled, the Party
      entitled to the amount in escrow shall  receive such amount  together with
      all  interest  thereon  and the other  Party  shall pay all costs and fees
      associated with such escrow.  In no event shall any Progress Payment prior
      to or including the Balloon  Payment be paid into escrow.  Customer's duty
      to make all  Progress  Payments up to and  including  the Balloon  Payment
      directly and timely to Hughes is not altered in any way by  Paragraph  4.8
      or this  Paragraph  4.9.  Under this  Paragraph  4.9,  Hughes shall not be
      obligated to proceed to Intentional  Ignition unless all required Progress
      Payments have been released to Hughes from escrow.

4.10  If Intentional  Ignition  occurs,  but the Satellite is not a Successfully
      Launched  Satellite,  any  remaining  payments  shall be payable to Hughes
      within thirty (30) days after, and to the extent of, Customer's receipt of
      applicable  proceeds  from Launch  Insurance (as such proceeds are paid to
      Customer,  whether in one  payment  or in  multiple  payments);  provided,
      however,  the Initial Incentive Amount and the  Paid-Over-Time  Incentives
      shall be payable to Hughes in accordance with Paragraph 5.4.

4.11  Amounts  payable to either Party shall be remitted by wire transfer to the
      following bank accounts, as applicable:

      In the case of Customer:
<TABLE>
<CAPTION>

<S>                                                                             <C>
      NationsBank
      Rockville, Maryland
      [              ]                                                          *
      [                 ]

      In the case of Hughes:
      Bank of America
      Concord, California
      [                  ]                                                      *
</TABLE>

      Any  payment  shall be deemed to have been made when credit for the amount
      is established in the above bank accounts, as applicable. Each Party shall
      notify  the  other in  writing  within  ten (10)  Days of a change  to its
      respective bank accounts.

4.12  The Parties  acknowledge  and agree  that,  with  respect to any  Progress
      Payment due prior to, and  including,  the Balloon  Payment,  Hughes would
      suffer  extreme  prejudice  as the result of any  delayed  receipt of such
      payments  and the rapid  decrease,  over  time,  of the value of the Work.
      Accordingly,  the Parties agree that time is of the essence in the receipt
      by Hughes of Progress  Payments up to and including  the Balloon  Payment,
      and,  subject to Article 17.3,  Hughes may, upon a default in such payment
      by Customer, immediately and without prior notice to Customer exercise all
      its rights and remedies under the Contract.

4.13  Subject to Paragraph  17.3,  up to and  including the date on which Hughes
      receives the Balloon Payment, the following shall apply:

      A.    Hughes' right to timely  payments  under the Contract is independent
            of any obligations Hughes may have to Customer; and


                                      -21-                                    

                                       
<PAGE>
      B.    Unless or until the Contract is terminated,  Customer shall make all
            payments  required  by the  Contract  to  Hughes  on a timely  basis
            regardless  of  whether  Hughes  shall  then  be in  breach  of  its
            obligations under the Contract; and

      C.    If Hughes breaches the Contract, Customer shall retain all rights to
            terminate  the Contract due to Hughes'  breach  and/or sue to obtain
            recovery of appropriate  damages for the breach,  but Customer shall
            not be entitled to delay or  withhold  timely  payments to Hughes on
            account of Hughes'  breach if Customer  did not also  terminate  the
            Contract.

4.14  With respect to Progress Payments up to and including the Balloon Payment,
      Hughes may suspend performance if Customer does not make any such Progress
      Payment on or before the due date for such Progress Payment.

4.15  No payment made by Customer prior to the Balloon  Payment shall be for the
      Delta III launch  vehicle.  Upon  receipt of the Balloon  Payment,  Hughes
      shall  dedicate  a Delta  III  launch  vehicle  from  its  launch  vehicle
      inventory to Customer for the purpose of launching the  Satellite.  Unless
      and until the Balloon  Payment  shall be received by Hughes,  Hughes shall
      have no duty to identify a Delta III launch  vehicle to Customer under the
      Contract.  Notwithstanding the foregoing,  in recognition of the fact that
      the  probability  of the  Satellite  being  launched on  schedule  will be
      maximized if Customer receives certain information on the Delta III launch
      vehicle  prior to  making  the  Balloon  Payment,  Hughes  shall  use best
      reasonable  efforts to provide  Customer access as described in Paragraphs
      12.1-12.5 and 12.9 to  information  regarding a launch vehicle of the same
      type as the Launch Vehicle.

4.16  Subject to the last  sentence of Paragraph  4.15,  Customer  shall have no
      interest in the Work, or any items  thereof,  unless and until it has made
      the Balloon Payment and all previous Progress  Payments.  Accordingly,  if
      Customer  shall  not make any such  payment  on a timely  basis  (provided
      Hughes has given  Customer at least ten (10) days prior  notice in writing
      of the payment due date) for any reason,  including Customer's  insolvency
      or 

                                      -22-


<PAGE>



      status as a debtor in bankruptcy, then Hughes shall have the right to stop
      Work immediately and to sell the Work, or items thereof, to another Person
      without notice to Customer. If Hughes decides not to sell the Work, Hughes
      shall be entitled to retain possession of the Work, and all items thereof,
      until  all  payments  current  or past due under  the  Contract  have been
      received in immediately available funds. .

4.17  The Parties agree that,  to the extent  permitted by law,  Customer  shall
      have no right,  title or interest in the Work prior to Hughes'  receipt of
      the Balloon Payment.  Notwithstanding the foregoing, until Hughes' receipt
      of the Balloon  Payment,  Customer  hereby grants Hughes a first  priority
      security interest in any right,  title or interest Customer may have or be
      deemed  to have in the Work to  secure  Customer's  obligations  to Hughes
      under  the  Contract.  Hughes  shall  have the  right to  include  in such
      financing  statements public notice  reasonably  acceptable to Customer of
      Customer's agreements in Paragraph 15.12 of the Contract. Hughes agrees to
      terminate such security  interest and terminate  such financing  statement
      concurrently with payment of the Balloon Payment.

4.18  All payments made by Customer to Hughes prior to and including the Balloon
      Payment, shall be deemed fully earned by Hughes upon receipt. Any payments
      due  after  the  Balloon  Payment  paid into  escrow  in  accordance  with
      Paragraph  4.8.A and  Paragraph 4.9 shall be deemed fully earned by Hughes
      (i) at the time the  dispute is  resolved  and (ii) to the extent any such
      escrowed amounts are ultimately determined to be due Hughes, regardless of
      whether such amounts have been released to Hughes from escrow.

4.19  Hughes  shall not be required to proceed to  Intentional  Ignition  unless
      Customer is current with all Progress Payments due under the Contract.

ARTICLE 5. SATELLITE PERFORMANCE INCENTIVE PAYMENTS

5.1   In the event the Satellite is a  Successfully  Launched  Satellite,  then,
      upon Final Acceptance,  the Initial Incentive Amount shall be paid to, and
      earned or  refunded  by,  Hughes in the manner and to the extent  provided
      hereunder:
<TABLE>


      A.    The Initial  Incentive  Amount  shall be allocated to the C-Band and
            Ku-Band 1 

            Repeaters as follows:

<S>                                                                             <C>
            C-Band Repeater [             ]       [             ]               *

            Ku-Band 1 Repeater [             ]    [             ]               *

      B.    For the C-Band and Ku-Band 1 Repeaters, respectively, the portion of
            the  Initial  Incentive  Amount to be paid  shall be  determined  in
            accordance with the following formula:

            Repeater Initial Incentive Amount  x      APTL          
                                                  -------------
                                                   Maximum APTL

            where the maximum  Aggregate  Predicted  Transponder Life (APTL) for
            the C-Band Repeater is 150 years [                                 ]*
            [    ] and for the Ku-Band 1 Repeater is 375 years [               ]*
            [                     ]  Two examples  illustrating how to determine*
            that part of the Initial Incentive Amount due after Final Acceptance
            follow:



            (1) If  the  C-Band   Repeater  and  Ku-Band  1  Repeater  at  Final
                Acceptance  are  determined  to have  APTLs of [               ]*
                [   ],  respectively,  then  Customer  shall be obligated to pay
                Hughes [                                                       ]*
                [         ] and [                                              ]*
                [               ], respectively.

            (2) If the C-Band  Repeater and Ku-Band 1 Repeater are determined at
                Final  Acceptance  to have  APTLs of [                  ] years,*
                respectively, then

                Customer  shall be  obligated  to pay Hughes [                 ]*
                [                                                              ]*

      C.    Hughes  shall earn and be  entitled  to retain a  percentage  of the
            Initial  Incentive  Amount for each Day of the Operational  Lifetime
            according to the number of Successfully  Operating Transponders that
            the Satellite has during such day, as described  below. In the event
            that it is determined for any Day of the Operational Lifetime of the
            Satellite  that  a  Transponder  is  not  a  Successfully  Operating
            Transponder,   Customer  shall   promptly   notify  Hughes  of  said
            discovery.  Upon  concurrence  by  Hughes  ( or in  the  event  of a
            dispute,  resolution  of the dispute in  Customer's  favor) that the
            Transponder  is not a  Successfully  Operating  Transponder,  Hughes
            shall  refund  to  Orion  for  each  Day  of  the  remainder  of the
            Operational   Lifetime  the  appropriate   portion  of  the  Initial
            Incentive Amount paid to Hughes, such portion calculated  consistent
            with examples (1) and (2) set forth below.

            (1) Example (1): If at Final Acceptance the APTLs for the C-Band and
                Ku-Band 1 Repeaters are maximum,  then for each Transponder that
                is  not  a  Successfully   Operating   Transponder   during  the
                Operational  Lifetime,  Hughes shall pay to Customer a refund as
                set forth below:

                refund  tables shown above in Table  5.1.C(1) are based upon the

5.3   Hughes shall be entitled to payment of Extended Incentives as follows:

      A.    In the event the Satellite continues to provide service for Customer
            after  expiration  of the  Operational  Lifetime  for which  service
            Customer  receives  customary   commercial  revenues   substantially
            equivalent to those that Customer would  customarily  receive if the
            Satellite were a normally  operating  satellite,  Customer agrees to
            pay to Hughes certain  amounts as specified  below in  subparagraphs
            (B) and (C).

      B.    With  respect  to the  C-Band  [                ]  or  Ku-Band 1 [ ]*
            [           ]  Repeaters,  the  amount  to be paid  for  each  Day a*

            maximum of that portion of the Paid-Over-Time  Incentive not paid by
            Customer to Hughes during the Operational Lifetime.

      D.    In the event the Satellite continues to provide service for Customer
            after  expiration  of the  Operational  Lifetime for which  Customer
            receives  revenues less than those  described  above in subparagraph
            (A),  the  daily  amount to be paid for each  Transponder  operating
            after  expiration of the Operational  Lifetime shall be a percentage
            of the respective  amounts set forth above in subparagraphs  (B) and
            (C), such percentage equal to the percentage of customary commercial
            revenues actually received by Customer.

      E.    Such  extended  incentive  payments  shall  continue  for as long as
            Customer receives customary  commercial revenues on the Satellite or
            until the allowable  maximum  amount  (excluding  any portion of the
            Initial Incentive Amount not paid to Hughes at Final Acceptance) has
            been reached, whichever occurs first.

5.4   In the event the Satellite is launched but is not a Successfully  Launched
      Satellite,  Hughes  shall  be  entitled  to  (i) payment  of  the  Initial
      Incentive  Amount  within  [         ] Days  after,  and to the extent of,*
      Customer's  receipt of  applicable  proceeds (as such proceeds are paid to
      Customer,  whether as a single  payment  or over  several  payments)  from
      Launch  Insurance and Customer shall not be entitled to receive any refund
      of the Initial Incentive Amount for such Satellite and (ii) payment of the

      Transponder  but is  capable  of  partial  operation  and the  Transponder
      continues to be operated by Customer for telecommunications  purposes, the
      Parties shall negotiate an equitable  adjustment of the Initial  Incentive
      Amount refund  (specified in Paragraph 5.1) and  Paid-Over-Time  Incentive
      payments  (specified in Paragraph  5.2),  taking  partial  operation  into

5.6   Any  assertion  by  Customer  that a  Transponder  is  not a  Successfully
      Operating Transponder shall be accompanied by technical data, reports, and
      analyses,  and Hughes shall be given an opportunity to verify all relevant
      data. Should Hughes disagree with such  determination and present evidence
      to the contrary,  then Customer  shall  consider such evidence and consult
      with Hughes. In the event that the disagreement  cannot be resolved,  then
      it may be disposed of in accordance  with  Article_30  (Applicable Law and
      Dispute Resolution).

5.7   The amounts to be refunded by Hughes under  Paragraph  5.1 and the amounts
      to be paid by Customer under Paragraph 5.2 and 5.3 shall be (i) calculated
      on a daily basis and (ii) invoiced in arrears and paid on a monthly basis.
      Any payment required to be made by one Party to the other Party under this
      Article 5 shall be made within  thirty  (30) Days after the first  Party's
      receipt of an invoice  certifying  the event  giving rise to such  Party's
      liability.

5.8   If a  Satellite  has not been,  or is not  being,  operated  as a Properly
      Operated  Satellite  and such  improper  operation  results in one or more
      Transponders  not meeting the  requirements  of a  Successfully  Operating
      Transponder, or the Operational Lifetime being reduced, Customer (i)_shall
      not be entitled  to receive  refunds of the  Initial  Incentive  Amount in
      accordance  with  Paragraph_5.1,  and  (ii)_shall  be  required to pay the
      Paid-Over-Time Incentive in accordance with Paragraph_5.2, with respect to
      the  Transponders  so affected  (and such affected  Transponders  shall be
      deemed to be Successfully Operating Transponders).

ARTICLE 6. LAUNCH VEHICLE DELAYS

6.1   In the event of postponement or delay of a Launch prior to shipment of the
      Satellite,  which  postponement or delay exceeds thirty (30) Days from the
      originally  scheduled  Launch Date (to be scheduled by the Parties  during
      the  Contract to occur no later than  November  30, 1998 absent  Excusable
      Delay)  and which  delay is not  caused  by  Hughes or its  Subcontractors
      (except the Launch  Provider)  or  Affiliates,  the price  included in the
      Contract  Price for Launch and  Mission  Operations  services  provided by
      Hughes (Table 4.2) shall be increased to reflect the cumulative  increase,
      if any, in the Consumer  Price Index for All Urban  Consumers,  All Cities
      Average, All Items, 1982-1984 ("CPI-U") published monthly by the Bureau of
      Labor  Statistics  or a  successor  agency  of the U.S.  Government.  Such
      cumulative  increase in the CPI-U shall be  determined  by  computing  the
      percentage  change in the CPI-U between November 1998 and the month actual
      delivery of the Launch and Mission Operations services  commences,  but in
      no case shall such cumulative  increase be less than an annualized rate of
      three percent (3%). If the Bureau of Labor  Statistics  redefines the base
      year, the Parties will adjust their  calculations  by using an appropriate
      conversion formula.

      In addition,  Customer  shall be responsible  for any and all  incremental
      expenses  actually  and  reasonably  incurred by Hughes  (and  invoiced to
      Customer in reasonable detail) and a profit of twelve and one half percent
      (12.5%) on such incremental  expenses  resulting from such postponement or
      delay.  Such  incremental  expenses may include,  as  appropriate  for the
      period of delay,  launch  crew  standby  time,  extra  launch  crew travel
      expenses,  transportation expenses for equipment, expenses associated with
      maintaining launch support capabilities, stretch-out program expenses, and
      storage expenses.

6.2   The  Contract  Price stated in  Paragraph_4.2  is based on a launch on the
      Delta III Launch Vehicle.

6.3   If failure to launch a Satellite on the originally  scheduled  Launch Date
      is due to anything other than the fault of Hughes or its Subcontractors or
      Affiliates, then

                                      -32-

      A.    Customer  shall make the  necessary  arrangements  for, and bear the
            costs of,  storage  of the  Satellite  until such  Satellite  can be
            launched.  Hughes shall cooperate in assisting  Customer to make the
            necessary  storage  arrangements  in a U.S.  storage  facility which
            conforms to Hughes'  standards  for  ensuring  the  integrity of the
            Satellite.

      B.    Except as provided in the second  sentence of Paragraph 6.3.A above,
            Customer shall reimburse Hughes for its extra expenses  actually and
            reasonably  incurred (and invoiced to Customer in reasonable detail)
            as a result  thereof  plus a profit of twelve  and one half  percent
            (12.5%) on such  expenses,  and the Contract  Price shall be revised
            accordingly;  and an  amendment  to  the  Contract  reflecting  such
            adjustments shall be entered into in accordance with Paragraph 35.5.

ARTICLE 7. PERMITS AND LICENSES;  GOVERNMENT APPROVALS

7.1   Hughes  shall,  at its own expense,  obtain all United  States  Government
      approvals,  permits and licenses as may be required for the performance of
      the Work under the  Contract.  Hughes shall perform the Work in accordance
      with all applicable laws, government rules,  regulations and ordinances of
      the United States  Government  and the  conditions of all such  applicable
      United States Government permits and licenses.

7.2   Hughes shall  review with  Customer  any  application  Hughes makes to any
      government  department,   agency,  or  entity  for  any  permit,  license,
      agreement or approvals,  as may be required for  performance  of the Work,
      prior to the submission of such application. Hughes shall provide Customer
      a minimum of three (3) Business Days to review such  application  prior to
      submission  to such  governmental  entity and  Hughes  shall in good faith
      consider  any  comments  and  proposed  revisions  made  by  Customer  for
      incorporation into such application.

7.3   Notwithstanding  this or any other  Article in the  Contract,  the Parties
      understand  and agree that  certain  restrictions  are placed on access to
      Hughes' plant and the use of Technical Data and  Information  and hardware
      delivered  under the Contract with relation to the approvals,  permits and
      licenses Hughes must obtain from the United States Government.

      As a result, and if applicable, the Parties agree that such access and the
      actual delivery of any Technical Data and Information will be at all times
      subject to United States  Government  approval.  Hughes shall prepare said
      agreement and in  consultation  with Customer  shall request United States
      Government approval.

7.4   The documentation and hardware  ("products")  furnished under the Contract
      will  be  authorized  by the  United  States  Government  for  export  for
      Customer's  ground  station in Australia.  The products may not be resold,
      diverted, transferred, trans-shipped or otherwise disposed of in any other
      country or in any other  manner,  either in their  original  form or after
      being  incorporated  through an intermediate  process into other end items
      without the prior written approval of the United States Government,  which
      approvals  are  


                                      -34-


<PAGE>

      the  sole   responsibility   of   Customer.   Additionally,   transferring
      registration  or control  to any other  person or  business  entity of the
      products  furnished under the Contract is considered an export and as such
      also requires  prior written  approval from the United States  Government,
      which  approvals  are  the  sole  responsibility  of  Customer.   Customer
      represents  and warrants  that the ultimate end use of the products is for
      telecommunications services.

7.5   Customer is responsible  for obtaining,  as may be required for performing
      the Work, all non-United States Government approvals, licenses and permits
      (exclusive  of those  required by Hughes'  suppliers  or  Subcontractors),
      including  those which may be  required  for Hughes to perform the Work in
      compliance  with the laws of any  country  in  which a ground  station  is
      established.  Hughes  agrees to  cooperate  with  Customer  in  Customer's
      efforts to obtain all required non-United States Government approvals.

7.6   Hughes shall not be  responsible  for any failure to obtain any  licenses,
      approvals or consents of any governmental authority, which failure results
      from Customer's inability to demonstrate Customer's financial viability or
      meet other financial requirements.

           TESTING AND FINAL ACCEPTANCE

8.1   Preliminary  inspections  of all Work  (including  the  deliverable  items
      listed  in  Paragraph  3.1)  may be made  by  Customer  or its  designated
      representative at Hughes' or a Subcontractor's plant. All such inspections
      shall be made in the  presence  of a  representative  of Hughes.  Customer
      shall  inform  Hughes in  writing of those  particulars  in which the Work
      performed  under  the  Contract  does  not meet  the  requirements  of the
      Contract,  and Hughes shall use its best reasonable efforts to remedy such
      defects.

8.2   Final  Acceptance of the Satellite shall arise upon successful  completion
      of in-orbit  testing in accordance with the  requirements of the Contract,

      Acceptance  Report) and  configuration  of the  Satellite for hand-over to
      Customer.

8.3   Prior to the shipment of the  Satellite,  Hughes shall  conduct a Pre-Ship
      Review in accordance  with the Test Plan at Hughes's  plant.  The Pre-Ship
      Review  shall  consist  of  reviewing  Satellite  ground  test  results in
      accordance with the Test Plan. Hughes shall provide ORION at least fifteen
      (15) days  advance  notice of the  Pre-Ship  Review.  ORION shall have the
      right to witness such review and the right to either  concur or not concur
      that the Spacecraft  meets the  requirements  of the Contract and is ready
      for shipment.

      A.    The Pre-Ship Review shall verify that:

            (1) The Satellite  ground  testing has been  completed in accordance
                with the requirements of the Contract;

            (2) Except as provided in (3) below,  all material  discrepancies or
                non-conformances  affecting  the  capability of the Satellite to
                perform its on-orbit mission throughout its Operational Lifetime
                have been corrected;



                                      -36-


<PAGE>
            (3) It is the  intent  of the  Parties  that  all  work  that can be
                accomplished  at  Hughes'  plant  will  be  completed  prior  to
                shipment to the Launch Site. Notwithstanding that intent, Hughes
                may, with regard to certain limited  non-conformances,  conclude
                that such  non-conformances  can be  effectively  remedied after
                shipment,  in which case Hughes  may,  after  consultation  with
                Customer, ship the Satellite to the Designated Launch Site.

            (4) The  Satellite,   ground  support  equipment  for  handling  the
                Satellite   in   preparation   for   launch,    and   supporting
                documentation  as specified in Exhibit A (Statement of Work) and
                Exhibit  B  (Satellite  Technical  Specification)  are ready for
                shipment based on an inspection of the Satellite and such ground
                support equipment and an examination of the data package.

      B.    Successful  completion  of the Pre-Ship  Review shall arise upon the
            occurrence of any of the following:

            (1) The Pre-Ship Review complies in all respects with the provisions
                of  Paragraph  8.3.A,  and  Customer   notifies  Hughes  of  its
                acceptance of the Pre-Ship  Review within five (5) Business Days
                following completion. Failure of Customer to provide Hughes with
                a notice of  either  acceptance  or  rejection  within  five (5)
                Business   Days  shall  be  deemed  to   constitute   successful
                completion of said review; or

            (2) The  Pre-Ship  Review  complies in all respects  with  Paragraph
                8.3.A  save  for  minor  non-conformances  that  have  not  been
                corrected  but which  Hughes  demonstrates  to  Customer  at the
                review  have  no  adverse  effect  upon  the  capability  of the
                Satellite  to  perform  its  on-orbit  mission   throughout  its
                Operational  Lifetime,  and  Customer  notifies  Hughes  of  its
                acceptance of the Pre-Ship  Review within five (5) Business Days
                following completion. Failure of Customer to provide Hughes with
                a notice of  either 


                                      -37-

   
<PAGE>


                acceptance  or rejection  within five (5) Business Days shall be
                deemed to constitute successful completion of said review; or

            (3) If the Pre-Ship  Review reveals  non-conformances  which require
                correction,  within five (5)  Business  Days after such  review,
                Customer shall request  correction of non-conforming  conditions
                affecting  the  Satellite  in  writing.  Hughes  shall,  at  its
                expense, promptly correct the non-conforming conditions referred
                to therein and, promptly following such correction, shall notify
                Customer that the corrections  have taken place and shall invite
                Customer  to send  representatives  to attend an  inspection  at
                which they will be entitled to verify that such corrections have
                been  satisfactorily  made. The provisions of this Paragraph 8.3
                shall  thereafter  apply similarly to that inspection as if that
                inspection was the original Pre-Ship Review.

      C.    Upon  successful  completion of the Pre-Ship  Review,  the Satellite
            shall be deemed to be Available for Shipment.

8.4   Prior to  integration  of the  Satellite  with the  Launch  Vehicle at the
      Designated  Launch Site, a Launch  Readiness Review (LRR) shall be jointly
      conducted  by Hughes and  Customer.  Hughes shall give  Customer  five (5)
      Business  Days  written  notice of the LRR.  The  purpose of the LRR is to
      confirm that the Satellite is ready for Launch. Prior to Hughes proceeding
      to  integrate  the  Satellite  with the  Launch  Vehicle,  any  defects or
      non-conformances  in the  Satellite or other  equipment as may remain from
      the Pre-Ship  Review,  or resulting from shipment or otherwise  discovered
      during  Satellite  launch  preparations,  shall  have  been  corrected  or
      dispositioned.  Upon successful completion of the LRR, the Satellite shall
      be  released  by  Customer  for  Launch  Vehicle  integration.  Successful
      completion  of the LRR  shall  arise  upon  the  occurrence  of any of the
      following:

      A.    The LRR demonstrates  compliance in all respects with the provisions
            of Paragraph 8.3, and Customer  notifies Hughes of its acceptance of
            the LRR at the LRR.  Failure of  Customer  to provide  Hughes with a
            notice of either  acceptance or 


                                      -38-

<PAGE>


            rejection  at the LRR  shall  be  deemed  to  constitute  successful
            completion of said review; or

      B.    The LRR  demonstrates  compliance  with Paragraph 8.3 save for minor
            non-conformances   that  have  not  been   corrected   which  Hughes
            demonstrates  at the review to Customer have no adverse  effect upon
            the  capability  of the  Satellite to perform its  on-orbit  mission
            throughout its Operational Lifetime, and Customer notifies Hughes of
            its acceptance of the LRR at the LRR. Failure of Customer to provide
            Hughes with a notice of either  acceptance  or  rejection at the LRR
            shall be deemed to constitute  successful completion of said review;
            or

      C.    If  the  LRR  reveals  non-conformances  or  defects  which  require
            correction,   at  the  LRR  Customer  shall  request  correction  of
            non-conforming   conditions  affecting  the  Satellite  in  writing.
            Failure  of  Customer  to  provide  Hughes  with a notice  of either
            acceptance  or  rejection  at the LRR shall be deemed to  constitute
            successful  completion of such review. Hughes shall, at its expense,
            correct such  non-conforming  conditions and defects and,  following
            such  correction,  shall notify Customer that the  corrections  have
            taken place and invite Customer to send representatives to attend an
            inspection to verify that such corrections have been  satisfactorily
            made.  Customer  shall notify Hughes of its acceptance of the LRR at
            the LRR.  Failure of  Customer  to provide  Hughes  with a notice of
            either  acceptance  or  rejection  at the LRR  shall  be  deemed  to
            constitute successful completion of such review. In the event of any
            disagreement  between  Customer and Hughes  relating to the LRR, the
            Senior Executive Level representatives of the Parties shall use best
            reasonable efforts to promptly resolve such dispute.

8.5   After  Launch  and  either  during  drift  orbit  or upon  arrival  of the
      Satellite at the Specified  Orbital Location (or a Storage Orbit specified
      by Customer,  as the case may be) Hughes shall commence  in-orbit testing,
      in consultation with Customer,  in accordance with the requirements of the
      Contract.  Hughes shall, at its expense,  seek to remedy,  in consultation
      with  Customer  and  in  accordance  with  standard   satellite   industry
      procedures,  

                                      -39-



<PAGE>



      any  anomalous  conditions  that may become  apparent  as a result of such
      testing,  and shall  retest as  necessary  subsequent  to taking  remedial
      action (if any).  Notwithstanding an anomalous condition or failure of the
      Satellite  or  any  Transponder  to  meet  the  specifications  and  other
      requirements  set forth in  Exhibits A and B (which  failure  the  Parties
      intend to address  through the  provisions  of the  Contract  dealing with
      Launch  Insurance  and  Performance   Incentives   payments),   successful
      completion  of in-orbit  testing  shall be deemed to have occurred on _the
      date in-orbit  testing is completed in accordance with the requirements of
      the Contract,  the Satellite is configured for hand-over to Customer,  and
      the certificate of completion  (accompanied  by the  Preliminary  In-Orbit
      Acceptance Report) is Delivered to Customer.

8.6   Prior to shipment of the Satellite Control Equipment to the sites selected
      by Customer,  Hughes shall conduct a Pre-Ship  Review at the Hughes plant.
      The Pre-Ship  Review shall be conducted in accordance  with the Test Plan.
      Hughes shall provide  Customer at least fifteen (15) Business Days advance
      notice of the Pre-Ship  Review.  Customer  shall have the right to witness
      such  review  and the  right  to  either  concur  or not  concur  that the
      Satellite  Control Equipment meets the requirements of the Contract and is
      ready for shipment.

      A.    Customer shall direct Hughes to ship the Satellite Control Equipment
            to the selected  site(s) upon successful  completion of the Pre-Ship
            Review. The Pre-Ship Review shall be deemed complete and preliminary
            acceptance occurs when the Parties agree that:

            (1) factory  acceptance  testing in  accordance  with Exhibit E (The
                Ground Segment) is complete;

            (2) all open  actions  have been closed or a closure  plan agreed by
                Customer; and

            (3) all non-conformances have been corrected or waived in writing by
                an  Authorized  Representative  of Customer in  accordance  with
                Paragraph

                                      -40-



<PAGE>


                35.2, except minor non-conformances which Hughes demonstrates to
                Customer  have no  adverse  effect  upon  the  operation  of the
                Satellite Control Equipment in accordance with Exhibit E (Ground
                Segment).

      B.    Customer  shall  not  withhold  its  preliminary  acceptance  of the
            Satellite Control Equipment for minor  non-conformances which Hughes
            demonstrates  to Customer have no adverse  effect upon the operation
            of the  Satellite  Control  Equipment in  accordance  with Exhibit E
            (Ground Segment).

8.7   Final  Acceptance  of the  Satellite  Control  Equipment  shall occur upon
      successful  completion  of  installation  and  checkout  of the  Satellite
      Control  Equipment at its  installation  site, an  acceptance  test of the
      complete  Satellite  Control Equipment system in accordance with Exhibit E
      (Ground  Segment),  and  closure  of all action  items  from the  Pre-Ship
      Review;  provided,  however,  if  there  is a delay  in  installation  and
      checkout  due  to   unavailability  of  hardware  or  facilities  not  the
      responsibility  of Hughes,  and in  particular  if the  beneficial  access
      obligations set forth in Article 29 (Customer's  Responsibilities) are not
      met by  Customer,  then  there  shall be a day for day  adjustment  to the
      Delivery Date for the Satellite  Control  Equipment and Customer  shall be
      responsible  for any expenses  actually and reasonably  incurred by Hughes
      (and invoiced to Customer in reasonable  detail)  directly  related to the
      delay.

8.8   Final  Acceptance of Contract  Deliverable  Data and  Documentation  shall
      occur only when the Contract  Deliverable Data and Documentation have been
      delivered at the place referenced in Table 3.1 of Article 3 in a condition
      fully conforming to the provisions of the Contract.  Contract  Deliverable
      Data  and  Documentation  shall  be  deemed  to  be in a  condition  fully
      conforming to the provisions of the Contract  unless  rejected by Customer
      in  writing  within  fifteen  (15)  Business  Days  after  receipt of said
      Contract Deliverable Data and Documentation by Customer.  If such Contract
      Deliverable  Data and  Documentation  are  unacceptable,  Customer  shall,
      within the said fifteen (15)  Business  Days,  notify Hughes in writing in
      which respects the Contract  Deliverable  Data and  Documentation  fail to
      conform  to  applicable   requirements  of  the  Contract.   Any  Contract
      Deliverable  Data


                                      -41-
<PAGE>


      and Documentation  that fail to conform to applicable  requirements of the
      Contract with respect to which Customer has so notified  Hughes in writing
      as being  non-conforming,  shall be deemed  under the Contract not to have
      been  Delivered  unless  and  until  the  defects  that  resulted  in such
      rejection  have been  remedied or  demonstrated  not to exist  pursuant to
      verification procedures in accordance with the Contract.

8.9   "Delivery"  shall be deemed to have  occurred  for each  deliverable  item
      under the Contract upon its Final Acceptance by Customer  pursuant to this
      Article 8.

ARTICLE 9. TITLE AND RISK OF LOSS

9.1   Risk of loss or damage to the Satellite to be delivered under the Contract
      shall pass from Hughes to Customer at the time of Intentional  Ignition of
      that Satellite. In the event of Intentional Ignition that fails to lead to
      Launch,  risk of loss shall revert to Hughes at the point in time when the
      Launch  Vehicle's  liquid engine has been safely shut down and Hughes will
      retain  risk of loss  until the next  Intentional  Ignition.  Title to the
      Satellite,  free and clear of all liens and encumbrances,  shall pass from
      Hughes to Customer at Final Acceptance of the Satellite in accordance with
      Article 8.

9.2   Title and risk of loss or damage to the Satellite  Control Equipment shall
      pass from Hughes to Customer at Final Acceptance of the Satellite  Control
      Equipment in accordance with Article 8.

9.3   The Parties agree that, upon Hughes' request,  the Customer shall sign and
      will  permit  Hughes  to file,  for  precautionary  purposes,  appropriate
      Uniform  Commercial  Code  financing  statements  or any similar  document
      having the same  effect in foreign  countries  reflecting  Hughes'  right,
      title,  and  interest  to the SCE  prior  to  transfer  of  title  in such
      deliverable  items  to  the  Customer,   provided  that  Hughes  shall  be
      responsible for preparing such financing  statements and terminating  such
      financing statements upon transfer of title in such items to Customer.

ARTICLE 10. EXCUSABLE DELAYS

With respect to Hughes'  performance of its obligations  under the Contract,  an
"Excusable Delay" shall be any delay in the performance of the Work caused by an
event  which  is  beyond  the  control  of  Hughes,   its   Affiliates  and  its
Subcontractors,  and not involving fault or negligence of Hughes, its Affiliates
or its  Subcontractors,  such as, but not  limited  to, any acts of  Government,
including  but not  limited  to the  Governments  of the  United  States and the
country  of any  foreign  ground  station  in  their  contractual  or  sovereign
capacities  (including the refusal,  suspension,  withdrawal,  or non-renewal of
export or import  licenses  essential to the  performance of the Contract);  war
(whether  declared or undeclared),  outbreak of national  hostilities,  or civil
insurrection;  fire;  earthquake;  flood; strike or work slowdown not reasonably
within  the  control  of  Hughes  or  Hughes  Communications,   Inc.;  epidemic;
quarantine  restriction;  freight embargo;  acts of God;  Customer's  failure to
perform its  obligations  as set forth in Article 29, and where such delay could
not have been  avoided by Hughes or its  Subcontractors  through the exercise of
reasonable  foresight or reasonable  precautions  and cannot be  circumvented by
Hughes through the use of reasonable efforts (for example,  alternate sources or
work-around plans); provided written notice is given to Customer promptly (under
the  circumstances)  after Hughes shall have first learned of the possibility of
such an event and provided  further that failure on Hughes' part to provide such
notice shall not prevent  such an event from  qualifying  as an Excusable  Delay
should  Customer  have actual  notice of the event  (e.g.,  an  earthquake  that
receives  nation-wide  publicity).  In addition,  any postponement by the Launch
Provider of Launch of the Satellite shall constitute Excusable Delay (whether or
not such postponement is d whether or not such  postponement  involves any fault
or  negligence  on the  part  of the  Launch  Provider)  subject  to the  notice
provisions set forth in the prior sentence.  Notwithstanding any other provision
of the  Contract,  in the event of such an  Excusable  Delay  there  shall be an
equitable  adjustment to the time for  performance of the affected Work, and the
schedule  of  payments  set forth in  Exhibit F (Payment  Plan) and other  terms
stated in the  Contract  as they are  applicable;  provided,  however,  that the
Parties agree that while it is  impossible  to foresee all of the  contingencies
and circumstances  associated with the types of Excusable Delay set forth above,
ordinarily the  occurrence of an Excusable  Delay shall not entitle Hughes to an
increase  in the  Contract  Price  (unless  such  Excusable  Delay is  caused by


                                      -44-
<PAGE>



postponement  by the  Launch  Provider  of the  launch  of the  Satellite  or by
Customer's  failure to perform  its  obligations  as set forth in Article 29, in
which cases  there may be an  equitable  adjustment  in the  Contract  Price for
incremental costs incurred by Hughes as a result of such Excusable  Delay);  and
provided  further that the occurrence of an Excusable Delay caused by Customer's
failure  to perform  its  obligations  as set forth in  Article  29  (Customer's
Responsibilities) shall not entitle Customer to an adjustment in the schedule of
payments set forth in Exhibit F (Payment Plan).

ARTICLE 11. LIQUIDATED DAMAGES FOR LATE DELIVERY
<TABLE>
<S>                                                                             <C>
11.1  In the event the  Satellite is not  Delivered  on or before the  Scheduled
      Delivery Date for the Satellite and such late delivery  prevents  Customer
      from  providing  service for which it has one or more  executed  contracts
      pursuant to which it would earn commercial  revenue,  then,  commencing on
      the first Day following the Scheduled  Delivery Date, and continuing for a
      period  thereafter  not to exceed [                            ] Days (the*
      "Damages  Period"),  the Contract  Price shall be reduced by  [          ]*
      [                                                                        ]*
      [                        ] for each Day during the Damages Period that the*
      Satellite has not been  Delivered;  provided,  however,  that the Contract
      Price reduction specified above will not be applicable with respect to any
      period during which an Excusable  Delay exists or during which the failure
      to Deliver the  Satellite is  attributable  to the  Customer's  failure to
      perform  any  of  its   responsibilities   under  Article  29  (Customer's
      Responsibilities),  or other  provisions  of the Contract (and the Damages
      Period will be extended, as appropriate, to reflect any such period).
</TABLE>

      As used above, the term "Scheduled  Delivery Date for the Satellite" shall
      mean the delivery date  specified for the Satellite in Article 3 (Delivery
      Schedule), as such date shall be extended, as appropriate,  to reflect all
      periods during which an Excusable Delay exists or any similar extension of
      time pursuant to Article 29 (Customer's Responsibilities), or as otherwise
      agreed  by  the  Parties  pursuant  to an  amendment  to the  Contract  in
      accordance with Paragraph 35.5 (Amendments).

11.2  Except as  provided  in  Paragraph  17.2,  the  Contract  Price  reduction
      specified in Paragraph 11.1 shall be the sole remedy available to Customer
      in  the  event  of a  late  Delivery  of  the  Satellite  to be  Delivered
      hereunder, and shall be in lieu of all damages of any kind or any right to
      terminate the Contract for default. The Contract Price reduction specified
      in Paragraph 11.1 shall  constitute  liquidated  damages for any such late
      Delivery (and shall not constitute a penalty),  the Parties  acknowledging
      that such liquidated  damages are believed to represent a genuine estimate
      of the losses that would be  suffered  by reason of

                                      -46-                                     

<PAGE>

      any such delay (which losses would be difficult or impossible to calculate
      with  certainty).  In the event the  Damages  Period has  expired  and the
      Contract  Price  has been  reduced  by the  maximum  amount  specified  in
      Paragraph 11.4,  then, at any time thereafter but prior to actual delivery
      of the  Satellite,  Customer  may  exercise  its  right to  terminate  the
      Contract for Hughes'  default  pursuant to  Paragraph_17.2,  in which case
      Customer's rights and remedies shall be governed by the provisions of that
      Article. Customer shall have no other rights or remedies for late Delivery
      of an item to be Delivered  under the  Contract.  The  liquidated  damages
      specified in  Paragraph_11.1  shall not be applicable to a Satellite which
      is delivered  for  purposes of storage,  unless the  requirement  for such
      storage was caused primarily by Hughes' unexcused delay.

11.3  In the event of a late  Delivery  requiring a reduction in Contract  Price
      pursuant to the foregoing,  the Parties shall, if  appropriate,  equitably
      adjust the payment plan set forth in Exhibit F (Payment Plan).

11.4  The maximum price reduction for late Delivery under the Contract  pursuant
      to  termination  under  Paragraph 17.2 shall never exceed Six Million U.S.

ARTICLE 12. ACCESS TO WORK-IN-PROGRESS AND DATA

12.1  Subject  to  Article  7  (Permits  and  Licenses:  Government  Approvals),
      Paragraphs 12.3 and 12.4 below, and Article 21 (Proprietary  Information),
      Hughes shall  provide  Customer  Personnel  reasonable  access to all Work
      (including  work-in-progress  and  observation of tests in accordance with
      the  requirements  of  Exhibit_D   (Acceptance  Test  Plan)),  at  Hughes'
      facilities,  at  reasonable  times  during  the  period  of the  Contract,
      provided that such access does not  unreasonably  interfere with such Work
      and access to Work is coordinated with the Hughes Program Manager or other
      person designated by Hughes for such purpose.  Subject to the restrictions
      set forth above,  Customer  Personnel shall also be afforded access to the
      Subcontractors'  facilities,  to the extent  that Hughes is  permitted  to
      provide such access, and subject to Hughes accompanying Customer Personnel
      on any such visit.

12.2  Work-in-progress,  technical and schedule data and documentation  directly
      related to the  Contract  shall be subject to  reasonable  evaluation  and
      inspection by Customer Personnel, subject to the restrictions set forth in
      Paragraphs_12.1,12.3 and 12.4.

12.3  Customer  Personnel  visiting at the Hughes facility or a  Subcontractor's
      facility (a) will abide by Hughes'  security  regulations  and/or those of
      its  Subcontractors  and applicable United States Government  regulations;
      (b) will  not  disclose  to a third  party  any  information  received  in
      connection  with  the  access   provided   hereunder  and  will  use  such
      information  only in the performance of the Contract,  whether or not such
      information is marked or otherwise identified as proprietary; and (c) will
      not remove any  documents,  materials  or other items from any facility of
      Hughes or its  Subcontractors  (other than Contract  Deliverable  Data and
      Documentation  and other  documents  delivered to Customer  Personnel  for
      Customer's use and with no  requirement  to return to Hughes)  without the
      express written consent of the Hughes Program Manager.

12.4  Customer  shall submit the individual  name(s) of any proposed  Consultant
      who will  have  access to the  plants  and/or  proprietary  data of Hughes
      and/or its Subcontractors to Hughes, which shall have the right to approve
      all such Consultants (whether paid or  


                                      -48-



<PAGE>



      unpaid).  Such  approval  shall not be withheld  by Hughes  unless (i) the
      hiring of such  Consultant  would  give rise to a  reasonable  concern  by
      Hughes   regarding  the  protection  of  its  proprietary  or  competitive
      information or compliance with its security  requirements or United States
      law,  and/or (ii) Hughes has  knowledge  of prior  incidents in which such
      Consultant has demonstrated behavior or activity incompatible with Hughes'
      ability to achieve the  objectives  of the  Contract.  In the event Hughes
      disapproves  a  Consultant  proposed by  Customer,  Hughes  shall  provide
      Customer with an  explanation,  which need not be written,  of its reasons
      for disapproval.

12.5  As a condition to access to the  facilities of Hughes,  its Affiliates and
      its Subcontractors under this Article, Customer agrees to indemnify Hughes
      as set forth in Paragraph 39.1 of the Contract.

12.6  Hughes shall  provide  office space and  facilities  (co-located  with the
      program  office)  for  the  accommodation  of up  to  three  (3)  Customer
      Personnel who are U.S. citizens, and if necessary, separate facilities for
      two (2) Customer  Personnel who are citizens of the Republic of Korea plus
      facilities for two (2) rotational U.S. Customer Personnel  co-located with
      the Koreans at Hughes' facilities. Hughes shall make reasonable work space
      available for such Customer Personnel at environmental test facilities (if
      located  off site) and shall use best  reasonable  efforts to ensure  that
      facilities are provided for up to two (2) such Customer Personnel at other
      selected Subcontractors' plants on a temporary basis to attend meetings or
      witness tests. At a minimum,  Hughes shall provide desks,  chairs,  office
      supplies,  local  telephone  service (long distance  telephone usage to be
      charged to Customer),  car parking facilities and access to meeting rooms,
      copying machines and facsimile equipment, and, as available, access to and
      use of video conferencing facilities at Hughes' facilities.

12.7  Customer  Personnel will have reasonable  access to (i) drawings,  circuit
      diagrams/schematics,  specifications,  standards  or process  descriptions
      available  to Hughes  and  relevant  to the  Satellite,  and (ii) data and
      documentation provided to Hughes by its Subcontractors and relevant to the
      Satellite (to the extent permitted by the Subcontractors

                                      -49-



<PAGE>




      after Hughes has used best efforts to obtain such  permission),  and (iii)
      Contract  Deliverable Data and Documentation.  Where such documentation is
      necessary   for   evaluation  of  designs,   performance   considerations,
      assessment  of test  plans  and  test  results  or for any  other  purpose
      connected with the design,  qualification,  testing,  Final  Acceptance or
      operation of the Satellite and its components,  Hughes will make available
      to Customer  Personnel  copies of such  documentation  (excluding unit and
      unit sub-assembly  design and process data), at no charge to Customer,  on
      the reasonable request of Customer Personnel.  To facilitate their work in
      this respect,  Hughes will allow Customer  Personnel  reasonable access to
      all   Customer-specific   indices   related  to  such  drawings,   circuit
      diagrams/schematics, and documents.

12.8  With  regard to  electronically  generated  information,  Hughes will copy
      Customer and/or provide Customer  electronic access to such information as
      is necessary to keep  Customer  advised,  on a current  basis,  of program
      issues,  decisions  and  problems.  Hughes  shall,  if  feasible,  provide
      Customer Personnel access to Hughes's  electronic mail systems through the
      Internet,  such  access to be at  Customer's  cost.  To the extent  Hughes
      establishes  data links for general use between the  facilities  of Hughes
      and its  customers,  Hughes  shall  establish  data links  between its and
      Customer's  facilities such that Customer has remote  electronic access to
      those project related  documents  identified in the CDRL. Hughes will also
      provide  Customer  Personnel  with "real time" access to all measured data
      for the Satellite taken at Hughes' and/or Subcontractor's  facilities on a
      non-interference, no-cost basis.

12.9  Customer  Personnel  shall be entitled to attend all  meetings and reviews
      (including meetings and reviews held by electronic means) of Hughes and of
      Hughes with any Subcontractors  where such meetings and reviews are solely
      related  to  Customer's  project  schedule  and  management,  engineering,
      design, manufacturing,  integration,  testing and launch (but not meetings
      relating  solely to  Hughes'  product  line)  and shall  have the right to
      participate  in  and  make  recommendations,  but  not  to  control,  give
      directions or assign  actions,  in all meetings and reviews at the system,
      subsystem  and unit level,  as well as in internal  program  reviews.  The
      Parties agree to work  cooperatively in resolving issues that 


                                      -50-



<PAGE>



      arise at the various  meetings and,  where  Customer has an objection to a
      recommended resolution/ implementation, the Parties agree to discuss it at
      the Senior  Executive  Level prior to  implementation,  provided  that the
      final decision  concerning  implementation  shall remain with Hughes,  who
      shall provide Customer with a written  explanation for its decision.  With
      respect to Hughes,  "Senior  Executive  Level" shall mean the President or
      Chairman of the Board of Hughes,  and with  respect to  Customer,  "Senior
      Executive  Level"  shall mean the Chief  Executive  Officer of Customer or
      Senior Vice  President,  Engineering  and  Satellite  Operations  of Orion
      Satellite Corporation.

      In  the  event  a  meeting  or  review  is   convened   at  Hughes'  or  a
      Subcontractor's plant relating to Customer's program, Hughes shall provide
      reasonable  advance  notice  to  Customer  and  shall  make  feasible  and
      appropriate  arrangements to facilitate the entry of Customer Personnel to
      the meeting place.

12.10 Hughes shall require that any Subcontract entered into after the Effective
      Date of Contract (other than bulk-buy  Subcontracts)  contains a provision
      substantially  similar to this Article 12 to ensure the  effectiveness  of
      Customer's rights under the Contract. With respect to Subcontracts entered
      into before the Effective Date of Contract,  Customer's  rights under this
      Article 12 shall be as  permitted  in such  Subcontracts.  With respect to
      bulk-buy Subcontracts for critical  sub-assemblies  entered into after the
      Effective Date, Hughes shall inform the Subcontractor of the provisions of
      this Article 12 relating to access to Subcontractor's work-in-progress and
      data and shall use  reasonable  efforts to request on Customer's  behalf a
      similar level of access.

12.11 Hughes'  obligations  under this  Article  shall be subject to  applicable
      United States  Government  regulations and Hughes' standard security rules
      and regulations.

12.12 Consultants  who are foreign  nationals may be afforded a more  restricted
      degree  of  access  to  Hughes'  facilities,  such  level of  access to be
      determined by Hughes in its reasonable discretion.

     
                                      -51-


<PAGE>

12.13 With  respect to foreign  nationals  access to design  and  process  data,
      Hughes will  provide to a location  designated  by Customer two data sets:
      one  properly  marked  for  U.S.  citizen  access;   and  a  second  (more
      restrictive)  data set  properly  marked for foreign  nationals.  Customer
      accepts  responsibility  for  proper  distribution  of each  data set in a
      manner that complies with all relevant  United States  Government laws and
      regulations.

12.14 Hughes  represents that the access to facilities and information  provided
      under the Contract is substantially  equivalent to that generally  granted
      to its commercial customers (excluding Hughes Communications,  Inc. or any
      successor entity).

12.15 It is the  intention  of the Parties  that the  measures set forth in this
      Article 12 shall afford  Customer  sufficient  visibility into the Orion 3
      Satellite Program such that Customer shall, throughout the duration of the
      Program,  be aware and  informed  with  respect to  material  developments
      affecting  Hughes'  ability to deliver the Satellite and other items to be
      delivered according to the requirements of the Contract and on schedule to
      meet the delivery dates set forth in Table 3.1 above.  In order to further
      facilitate  this  objective,  Hughes  shall  advise  Customer  promptly by
      telephone and confirm in writing any event,  circumstance  or  development
      that in Hughes' reasonable  judgment Customer should not have become aware
      of via the other  measures  set forth in this  Article 12 and that,  after
      considering the applicability of reasonable remedial measures,  materially
      threatens (i) the quality of the Satellite or any component  part thereof,
      as well as any services, Contract Deliverable Data and Documentation, SCE,
      Ground Control Software, or (ii) any delivery dates set forth in Table 3.1
      of Article 3.

ARTICLE 13. INTER-PARTY WAIVER OF LIABILITY

13.1  All operations at the Designated Launch Site pursuant to the Contract will
      be subject to a no-fault,  no-subrogation  inter-party waiver of liability
      under which Customer,  Hughes and each other Person conducting  operations
      at the  Designated  Launch Site,  including  the Launch  Provider  ("Other
      Users"),  agrees  to be  responsible  for any loss or  liability  which it
      sustains  as a  result  of  damage  to its  own  property  and  employees,
      including death, while involved in operations,  whether or not such damage
      arises through  negligence of any Person.  It is the intent of the Parties
      that this inter-party  waiver of liability be construed broadly to achieve
      its intended objectives of clarifying and minimizing the risk of liability
      to third parties arising from Launch Operations.  Prior to commencement of
      Launch Operations,  Customer will provide Hughes with evidence  reasonably
      satisfactory  to Hughes  that all other such  Persons  have agreed to such
      inter-party waiver of liability.

13.2  If either Party  contracts or  subcontracts  with a third party to provide
      services which necessitate the contractor's or subcontractor's presence on
      the  Designated  Launch  Site,  then such Party will also ensure that such
      third  party  agree to a no-fault,  no-subrogation  inter-party  waiver of
      liability and indemnity for damages it sustains, identical to the Parties'
      respective undertakings under this Article.

13.3  In the event that either  Customer or Hughes fails to obtain the aforesaid
      inter-party  waiver of  liability  and  indemnity  from  their  respective
      contractors or  subcontractors,  then such Party shall  indemnify and hold
      the other Party, the Launch  Provider,  the Other Users of launch services
      and their respective  contractors and subcontractors  harmless from claims
      brought by such  Party's  subcontractors  with  respect  to  matters  that
      otherwise would have been covered by the inter-party waiver of liability.

13.4  The Parties will take such further actions as may be required to implement
      the  provisions  of this  Article  13,  including  the  execution  of such
      agreements and waivers as are customarily  used with respect to operations
      at the Designated  Launch Site and are  consistent  with the provisions of
      this Article 13.

      specified by Exhibit E (Ground  Segment).  With  respect to the SCE,  this

      Delivery is delayed  beyond the Scheduled  Delivery  Date, up to a maximum
      extension of twelve (12) months.


                                      -54-


<PAGE>


14.5  Customer  shall  have the  right  at any time  during  the  period  of the
      warranties set forth in Paragraphs  14.1,  14.2, and 14.3 (as the warranty
      periods set forth in Paragraphs 14.2 and 14.3 may be extended  pursuant to
      Paragraph  14.4) to require that any Work not  conforming  in any material
      respect to the Exhibits to the Contract be promptly  corrected or replaced
      (at Hughes' option and expense) with  conforming  Work. If Hughes fails to
      correct or replace such  defective  Work within a reasonable  period after
      notification from Customer, Customer may then require Hughes to repay such
      portion of the Contract Price as is equitable under the  circumstances  in
      lieu of repairing or replacing such defective Work.

14.6  Hughes  covenants that it shall assign properly  qualified and experienced
      personnel to the Orion 3 Satellite Program contemplated by the Contract.

14.7  Hughes  represents  and  warrants  that it is  either  the  owner  of,  or
      authorized to use and incorporate,  any software or invention  utilized or
      incorporated in the Work.

            Contract; and

      B.    the  execution,  delivery  and  performance  of the Contract and the

            and

      C.    it has (and will have  throughout  the period of  performance of the
            Contract)  adequate  financial  resources to fulfill its obligations
            hereunder, including any repayment obligations upon termination; and

      D.    it will,  until  Final  Acceptance,  provide  Customer  with  Hughes
            Electronics Space Segment quarterly financial statements (profit and
            loss/balance sheet) evidencing Hughes' financial ability to perform;
            and

ARTICLE 15. ORION'S REPRESENTATIONS, WARRANTIES, COVENANTS AND ACKNOWLEDGMENTS

      Unless specifically  specified  otherwise,  references to Customer and ONS
      refer only to those entities as distinct and separate  corporate  entities
      and not to any of their  subsidiaries or Affiliates.  Customer and/or ONS,
      as the context dictates, represent and warrant to Hughes as follows:

15.1  Organization, Good Standing and Qualification. As of the Effective Date of
      Contract,  each of  Customer  and  ONS is a  corporation  duly  organized,
      validly  existing  and in good  standing  under  the laws of the  State of
      Delaware.  Each of Customer and ONS has all requisite  power and authority
      to own and operate its material  properties and assets and to carry on its
      respective  business as now conducted in all material  respects.  Customer
      and ONS are each  duly  qualified  to  transact  business  and are in good
      standing in each  jurisdiction  in which the  failure to so qualify  would
      have a Material Adverse Effect (as hereinafter  defined).  For purposes of
      this  Article  15,  the term  "Material  Adverse  Effect"  shall  mean any
      material adverse change in (a) the legality, validity or enforceability of
      the  Contract,  or (b) the  ability  of  Customer  or ONS to  perform  the
      Contract or (c) the financial condition or operations of Customer or ONS.

15.2  Authorization. Customer and ONS each has all corporate and other requisite
      authority to execute, deliver, carry out and perform its obligations under
      the terms of the Contract and all the transactions contemplated hereunder.
      The Contract and the consummation of the transactions  contemplated hereby
      have been duly and validly authorized by all requisite corporate action on
      behalf of Customer and ONS.

15.3  Capitalization  and  Subsidiaries.  As of the Effective  Date of Contract,
      Customer and ONS do not presently own or control,  directly or indirectly,
      any interest in any other corporation,  partnership,  association or other
      business entity or have any subsidiaries,  except those listed in Schedule
      15.3. Schedule 15.3 also includes a listing of the percentage ownership of
      Customer or ONS, as the case may be, in the foregoing entities.

<PAGE>



15.4  Litigation.  As of the Effective  Date of Contract,  except as provided on
      Schedule   15.4,   there  are  no  actions,   suits,   or  proceedings  or
      investigations  Pending,  or, to the  knowledge  of  Customer  and/or ONS,
      threatened  against  either  Customer  or ONS  which  ONS is  required  to
      disclose in its filings  under the  Securities  Exchange  Act of 1934,  as
      amended.  In  addition,  neither  Customer  nor ONS  currently  intends to
      initiate  such an action.  For purposes of the Contract,  "Pending,"  when
      used in the context of legal action, lawsuit, proceeding or investigation,
      shall  mean an  action,  suit,  proceeding  or  investigation  as to which
      Customer or ONS shall have knowledge or received written notice.

15.5  Certain  Actions.  Except as set forth on Schedule  15.5  hereto,  neither
      ORION  nor ONS has,  from  September  30,  1996 to the  Effective  Date of
      Contract,  incurred any indebtedness of Five Hundred Thousand U.S. Dollars
      (U.S.  $500,000) or more, or sold,  exchanged or otherwise disposed of any
      of its material assets or rights.

15.6  Title to Properties and Assets.  Customer owns its material properties and
      assets, other than leased properties, free and clear of all liens, charges
      and  encumbrances,  except for (a) such encumbrances and liens which arise
      in the ordinary course of business and do not materially impair Customer's
      ownership  or use of such  property  or assets,  (b) liens  created by the
      Contract and (c) liens listed on Schedule 15.6.

15.7  Financial  Statements.  Customer  has  delivered  to  Hughes  the  audited
      consolidated statements of operations, changes in shareholders' equity and
      cash  flows for each of the three (3) years in the period  ended  December
      31,  1995,   including  the  notes  thereto,  of  ONS  and  the  unaudited
      consolidated  balance  sheets at September 30, 1996 and related  unaudited
      consolidated  statements  of  operations  and cash  flows for the nine (9)
      months  then ended of ONS  (together,  the  "Financial  Statements").  The
      Financial  Statements  have  been  prepared  in  accordance  with GAAP and
      present  fairly  in  all  material  respects  the  consolidated  financial
      condition,  cash flow,  results of operations and changes in  stockholders
      equity of ONS and its subsidiaries  for such periods.  Except as disclosed
      in  Schedule  15.7,  from  September  30,  1996 to the  Effective  Date of
      Contract,  there  has not  been (a) any  material  adverse  change  to the
      financial condition of ONS or any of its 

                                      -58-

      subsidiaries,  or (b) any  damage,  destruction  or loss,  whether  or not
      covered by insurance,  which has had a Material Adverse Effect.  Except as
      disclosed  in  the  Financial  Statements  or in  Schedule  15.7,  neither
      Customer nor ONS is a guarantor or indemnitor of any material indebtedness
      of any other person,  firm or corporation.  ONS, on a consolidated  basis,
      maintains  and will  continue to maintain a standard  system of accounting
      established and administered in accordance with GAAP.

15.8  Undisclosed Liabilities.  As of the Effective Date of Contract,  except as
      set  forth on  Schedule  15.7 or on any  other  Schedule  hereto,  neither
      Customer  nor ONS is subject to any  liabilities  of any  nature,  whether
      absolute,  contingent or otherwise  (whether or not required to be accrued
      or disclosed under the accounting  disclosure standards applicable to such
      entity)  which have had or can  reasonably  be expected to have a Material
      Adverse  Effect,  except  to the  extent  set  forth  or  provided  in the
      Financial  Statements.  Except as set forth in Schedule  15.7 or any other
      Schedule hereto, all debts,  liabilities and obligations  incurred by such
      entities, after the date of the Financial Statements, were incurred in the
      ordinary  course of  business  and are in amounts  less than Five  Hundred
      Thousand U.S. Dollars (U.S. $500,000).

15.9  Disclosure.  As of the  Effective  Date of Contract,  neither the Contract
      (including the  representations  and warranties of this Article 15 and the
      related  Schedules) nor any of the written statements or certificates made
      or  delivered  in  connection  herewith  to the extent  such are listed in
      Schedule  15.9  (including  the filings  made by ONS under the  Securities
      Exchange Act of 1934,  as amended,  which have been provided to Hughes and
      are listed in Schedule 15.9),  contains any untrue statement of a material
      fact or omits to state a material  fact  necessary to make the  statements
      herein or  therein,  in light of the  circumstances  under which they were
      made, not misleading.

15.10 Compliance with Other  Instruments.  To the knowledge of Customer and ONS,
      as of the  Effective  Date of  Contract,  neither  Customer  nor ONS is in
      violation or default of its respective Certificate of Incorporation or its
      respective  By-Laws,  or in material default of any instrument,  judgment,
      order,  writ,  decree or oral or written  contract or other  

                                      -59-

      agreement  to  which  it is a party  or by  which  it is  bound  or of any
      provision  of  federal,   state  or  local  statute,  rule  or  regulation
      applicable to such entities as of the date hereof where such  violation or
      default will have a Material Adverse Effect.  The execution,  delivery and
      performance  of the  Contract  and the  consummation  of the  transactions
      contemplated  hereby  will not (i) result in any such  violation  or be in
      conflict  with the  Certificate  of  Incorporation  or the By-Laws of such
      entity, or (ii) be in conflict with any instrument, judgment, order, writ,
      decree, or (iii) be in conflict with any contract or other agreement or be
      an event which results in the creation of any lien,  charge or encumbrance
      upon any material  asset of any of such entities other than as provided in
      the  Contract,  where  such  conflict  or  creation  would have a Material
      Adverse Effect.

15.11 Customer's  Financial Strength.  Hughes and Customer acknowledge and agree
      that Hughes,  in entering  into the  Contract,  is relying on the separate
      existence  and  financial  strength  of  Customer  alone  and  not  of any
      Affiliate of Customer.

15.12 Other Commitments. The following representations and covenants of Customer
      only apply prior to Hughes'  receipt of the Balloon Payment (and shall not
      apply to any  financing  entered  into by  Customer,  ONS,  or  Customer's
      Affiliates  to obtain the funding for such  payment  which  results in the
      Balloon Payment being made substantially  concurrently with such financing
      being obtained for the Balloon Payment):

      1)    Customer  represents  and warrants that its assets do not secure the
            liabilities of ONS  ("Parent"),  Orion  Atlantic,  L.P. or any other
            person,  and prior to Hughes' receipt of the Balloon  Payment,  will
            not grant such a security interest.

      2)    Customer  represents  and warrants that, as of the Effective Date of
            Contract,  it is not a  party  to  any  financing  agreements  which
            contain a provision  that a default by any third party in such third
            party's  obligations  will  be a  default  under  any of  Customer's
            financing  agreements where  enforcement of such provision is likely
            to have a material adverse effect on the ability of Customer to make
            the  Balloon

                                      -60-

            and  interest in the Work or the  security  interest  held by Hughes
            therein.

      3)    Customer agrees that it shall not agree to a provision in any of its
            financing agreements that a default by any third party in such third
            party's  obligations  will  be a  default  under  any of  Customer's
            financing  agreements  unless the  lender  provides  Hughes  with an
            express  acknowledgment  of those Hughes'  rights under the Contract
            listed in  Schedule  15.12 and agrees not to contest  those  rights.
            Further,  Customer will not agree to such  provision if it is likely
            to have a material adverse effect on the ability of Customer to make
            the  Balloon  Payment or have a material  adverse  effect on Hughes'
            right,  title and interest in the Work or the security interest held
            by Hughes therein.

15.13 ONS represents and warrants that, as of the Effective Date of Contract, to
      ONS' knowledge, no competing satellite vendor has any claim against Hughes
      based on any relationship,  contract or understanding  between Customer or
      ONS and any competing  satellite  vendor arising out of Hughes' entry into
      the Contract.  Customer and ONS shall  indemnify and hold Hughes  harmless
      for any breach of the immediately foregoing representation and warranty.

15.14 Customer  and ONS  represent  and warrant  that the payments to be made to
      Hughes under the Contract  shall be made by Customer and shall not be from
      funds  that are held by  Customer  in either an  express  or  constructive
      trust.  Customer and ONS shall  indemnify and hold Hughes harmless for any
      breach of these representations and warranties.

15.15 ONS shall  indemnify  and hold Hughes  harmless  against any damages  that
      arise from the ORION 3 Satellite business  contemplated by the ATP and the
      Contract  competing with the business of International  Private  Satellite
      Partners, L.P. d/b/a ORION Atlantic, L.P.

15.16 Customer  acknowledges  that the Republic of Marshall  Islands licenses or
      consents  with respect to the Specified  Orbital  Location for the ORION 3
      Satellite are held by an entity other than Customer.

      subsidiaries (collectively "Loral").

15.18 Customer and ONS represent and warrant that Customer has been and shall be
      operated as an independent and separate  corporate  entity from ONS. As of

ARTICLE 16. TAXES AND DUTIES

16.1  This Paragraph 16.1 applies only to goods and services delivered by Hughes
      to any foreign country pursuant to the  requirements of the Contract.  The
      Contract   Price   excludes,   and  Hughes  and  Hughes'   Affiliates  and
      Subcontractors  shall  not be  required  to pay,  any  present  or  future
      non-U.S.   taxes,   duties,   fees,  levies,   bonds,   duties,   charges,
      contributions,  or any other such fiscal  burden  based on the delivery by
      Hughes of goods or services to Customer in any foreign country pursuant to
      the requirements of the Contract  imposed by any  jurisdiction  other than
      the United States or the State of California, including the following:

      A.    Taxes,  customs,  duties,  or other charges levied on goods imported
            into  or  services  delivered  in  any  foreign  country  under  the
            Contract; and

      B.    Taxes, customs,  duties, or other charges levied on materials,  test
            equipment,  tools, and documentation  temporarily  imported into any
            foreign  country  which  are  required  for the  performance  of the
            Contract; and

      C.    Income  taxes or business  taxes  levied by any  foreign  country on
            goods or  services  delivered  directly  by Hughes to  Customer in a
            foreign country; and

      D.    Value  added  taxes or any  similar  taxes  imposed  by any  foreign
            country  on  goods or  services  delivered  directly  by  Hughes  to
            Customer in a foreign country.

16.2  Hughes shall consult with Customer or its designated  Consultant(s) on any
      taxes or duties which may be payable under  Paragraph  16.1 above.  In the
      event any of the items in 16.1 above are levied  upon  Hughes,  or Hughes'
      Affiliates or  Subcontractors,  Hughes shall immediately  notify Customer.
      Customer,  within five (5) Business  Days of receipt of such  notification
      from  Hughes,  shall  either  have the  charges  waived or pay the charges
      directly. For those items in Paragraph 16.1 that Hughes is required by law
      to pay,  Customer shall reimburse  Hughes in an amount which leaves Hughes
      in  the  same  economic  position  as  if  such  payment  of  charges  and
      reimbursement  thereof had not been  required,  within thirty

                                      -64-

      (30) days of Customer's receipt of Hughes' invoice.  Hughes' reimbursement
      request will be  accompanied by evidence of the amount and purpose of such
      payments,  and shall include a calculation of the amount of  reimbursement
      required under the preceding sentence.

16.3  Hughes shall be responsible  for and shall pay all United States  (federal
      and state) taxes, fees, levies,  duties and other lawful charges which are
      levied  upon  Hughes  or  its   Affiliates  in  connection   with  Hughes'
      performance  of the Work  under the  Contract,  except  those  levied as a
      result  of  transfer  of  title in the  United  States  for an  unlaunched
      Satellite as described in Article 32.5.

ARTICLE 17. TERMINATION AND OTHER RIGHTS

17.1  Termination for Customer's Convenience

      A.    Customer may, upon written  notice to Hughes,  at any time terminate
            the Work in  accordance  with the terms set forth below,  and Hughes
            shall  immediately  cease  Work  in the  manner  and  to the  extent
            specified. Notwithstanding the foregoing, in no event shall there be
            a termination under this Paragraph 17.1 after Intentional Ignition.

      B.S   Upon   receipt  of  a  notice  of   termination,   as   provided  in
            Paragraph_17.1.A above, Hughes shall take the following actions:

            (1) stop  Work  under  the  Contract  on the date and to the  extent
                specified in the notice of termination;

            (2) place no further orders or subcontracts for materials, services,
                or facilities;

            (3) terminate orders and subcontracts to the extent that they relate
                to the performance of the Work;

            (4) settle all outstanding liabilities and all claims arising out of
                such  termination  of orders  and  subcontracts  for  materials,
                services, or facilities; and

            (5) take such action as may be reasonably necessary,  or as Customer
                may direct,  for the protection and preservation of the property
                related to the Contract  which is in the possession of Hughes or
                any  Subcontractor  and in which  Customer has or may acquire an
                interest.

      C.    In the event of termination under this  Paragraph 17.1  and provided
            the termination is not due to Hughes' default under  Paragraph 17.2,
            Hughes  shall be  entitled  to  payment  of an  amount  equal to the
            Termination  Liability  Amount as specified  in  Exhibit F  (Payment
            Plan)  less  the sum of all  amounts  (including  the  ATP  Payment)


                                      -65-
<PAGE>

            received by Hughes under the  Contract;  provided  that in the event
            such amount is a negative number, Hughes shall refund such amount to
            Customer.

      D.    Hughes  shall  submit an invoice to Customer  within sixty (60) Days
            after the termination  date,  which invoice shall specify the amount
            due to Hughes from  Customer  pursuant to this  Paragraph 17.1,  and
            Hughes  shall be  entitled  to payment by  Customer  of such  amount
            within  thirty (30) Days  thereafter.  Payment of such amount by any
            Financing  Entity on behalf of Customer shall relieve  Customer from
            its obligation to make such payment.

      E.    The   amount   payable   by   Customer   to   Hughes   pursuant   to
            Paragraph 17.1.C  shall  constitute a total  discharge of Customer's
            liabilities   to   Hughes   for   termination   pursuant   to   this
            Paragraph 17.1.

      F.    In the event of  termination  pursuant to this  Paragraph 17.1 after
            Hughes' receipt of the Balloon Payment,  upon payment of all amounts
            due hereunder, then

            (1) title to all items of Work which  would  have been  incorporated
                into a  deliverable  item under the  Contract,  and which are in
                progress  before  the  giving of notice  under  Paragraph 17.1.A
                above,  shall,  subject to applicable  United States  Government
                export regulations,  vest in Customer,  and Hughes shall deliver
                all  such  items to  Customer  FOB  Hughes  plant,  El  Segundo,
                California  (at which point  Customer  shall accept such items);
                and.

            (2) Hughes agrees to refund to Customer the  difference  between (x)
                the lesser of (i) the price of the Launch  Services set forth in
                Paragraph  4.2  ("Launch  Services  Price")  and (ii) the resale
                price of such  Launch  Services to a third party and (y) Hughes'
                additional  actual costs incurred to resell such Launch Services
                (including  unrecoverable  costs charged by the Launch  Provider
                such  as:  inventory  carrying  fees;  reasonable  reprogramming
                costs;  and  profit),  plus a profit on such  additional  actual
                costs of twelve and one-half

                percent  (12.5%);  provided  that in the event  Customer has not
                paid in full the Launch  Services Price (taking into account any
                termination  liability  payment  made by  Customer)  the "resale
                price" in (x) above  shall be  adjusted,  for  purposes of these
                calculations,  by multiplying  such "resale price" by the amount
                Customer has paid for the Launch  Services  (taking into account
                any  termination  liability  paid by  Customer)  divided  by the
                Launch  Services  Price (for example,  if Customer has paid only
                [         ]  of the  Launch  Services  Price  [           ]  and*
                Hughes  resells the Launch  Services for [            ] then the*
                "resale  price"  for  purposes  of (x) shall be  adjusted  to be
                [                         ]   times   [         ]   divided   by*
                [          ])).  Hughes agrees to use best reasonable efforts to*
                resell the Launch Services during the eighteen (18) month period
                following said termination and amounts realized from such resale
                will be  refunded to  Customer  thirty  (30) days after  Hughes'
                receipt of such resale  payments  from the third  party.  Hughes
                shall use best reasonable efforts to sell the Launch Services at
                fair market value (at the time of such resale).
</TABLE>

      G.    If in Hughes' sole judgment it is feasible for Hughes to utilize any
            items of  terminated  Work,  it shall submit to Customer an offer to
            acquire such items. If such offer is accepted,  Hughes'  termination
            invoice shall be credited with the agreed acquisition price.  Hughes
            shall have no obligation to use any of the Work in any other project
            or for any other customer and any decision to do so shall be made at
            Hughes' sole discretion.

      H.    This  Paragraph  17.1 shall apply only to a complete  termination of
            the Work. Customer requests for termination of only a portion of the
            Work shall be presented to Hughes and negotiated pursuant to Article
            22 (Changes).

      B.    Customer's  service of a Default  Notice on Hughes shall  operate to
            terminate  the Contract  forthwith  with respect to the Work. In the
            event   Customer    terminates   the   Contract   as   provided   in
            Paragraph 17.2.A,  Customer  shall be  entitled  to a refund  of all
            payments (including the ATP Payment) previously made to Hughes

            provisions of this Paragraph 17.2, or that the default was excusable
            under  Article 10  (Excusable  Delays),  such  termination  shall be

            termination  pursuant  to  Paragraph  17.2.A(1),  there  will  be no
            termination for default with respect to a launched Satellite.

      A.    Hughes may  terminate  the Contract in whole without prior notice to
            Customer at any time after the occurrence of any of the following:

            (1) If  Customer  is in  default of any  Progress  Payment up to and
                including the Balloon Payment;  provided,  however, where Hughes
                failed to provide the invoice  specified  in  Paragraph  4.7 for
                such  payment,  Hughes  shall not be entitled to  terminate  the
                Contract for  Customer's  default in making such payment  unless
                and until  Hughes  provides  Customer  such an invoice  for such
                payment and fails to receive such  payment  within ten (10) Days
                after  Customer's  receipt (as  specified in Article 24) of such
                invoice; or

            (2) If Hughes  gives  written  notice to  Customer of default in the
                payment of any  Progress  Payment due after the Balloon  Payment
                when such Progress Payment shall have become due and payable and
                Customer  fails to cure such event within thirty (30) Days after
                receiving such written notice; or

            (3) Customer  commences a  voluntary  proceeding  concerning  itself
                under any  applicable  bankruptcy,  insolvency,  reorganization,
                adjustment   of  debt,   relief  of  debtors   or  similar   law
                ("Insolvency  Law");  or any  involuntary  proceeding  commences
                against  Customer  under an Insolvency  Law and the petition has
                not been dismissed within ninety (90) Days after commencement of
                the  proceeding;  or a receiver or custodian is appointed for or
                takes charge of all or a substantial  portion of the property of
                Customer and such  custodian or receiver has not been  dismissed
                or  discharged  within  sixty (60) Days;  or Customer  has taken
                action toward 

                                      -70-

                the  winding-up,  dissolution  or liquidation of Customer or its
                business; or Customer has been adjudicated insolvent or bankrupt
                or an order  for  relief  or  other  order  approving  a case or
                proceeding under an Insolvency Law has been entered; or Customer
                has made a general  assignment  for the benefit of  creditors or
                becomes unable to pay its debts generally as they become due; or

            (4) Customer has assigned or  transferred  the Contract in violation
                of the  provisions  of  Article  26  (Assignment  or  Change  in
                Ownership  or  Control)   and   Customer   fails  to  cure  such
                unauthorized  assignment  or  transfer  within  thirty (30) days
                after receiving written notice.

      B.    Upon  the  occurrence  of  an  event  of  default  under   Paragraph
            17.3.A(1), Hughes' sole and exclusive remedies against Customer, ONS
            and any Orion  Affiliate (in addition to those remedies set forth in
            Paragraph 17.3.A(1)) shall be the following:  (i) Hughes may, at its
            sole option, terminate its obligation to dedicate a Delta III launch
            rocket to the  Contract  without  terminating  the  remainder of the
            Contract;  (ii) Hughes may immediately stop Work; (iii) Hughes shall
            be entitled,  as liquidated  damages, to retain possession and title
            of the Work, and all items thereof,  and all payments received prior
            to such  termination  until all payments due under the Contract have
            been  received in  immediately  available  funds;  and (iv) sell the
            Work,  or  items  thereof,  to  another  Person  without  notice  to
            Customer. Nothing in this subparagraph 17.3.B shall limit any rights
            (and associated  remedies to enforce those rights) Hughes has in the
            Work by virtue  of law or its  security  position  as  permitted  in
            Paragraphs  4.17 and 9.3 or any  rights  either  Party has under the
            existing Non-Disclosure Agreement between the Parties.

      C.    Upon the occurrence of an event of default under Paragraph 17.3.A(3)
            above,   Customer  shall,   upon  the  written  request  of  Hughes,

      D.    Upon the  occurrence of an event of default  under  Paragraph 17.3.A
            above (other than under Paragraph  17.3.A(1)),  Hughes' remedies (in
            addition  to those  set  forth  in  Paragraph  17.3.A)  shall be the
            following:

            (1) Customer   shall  pay  to  Hughes  the  amounts   specified   in

            (2) Hughes shall have the right to  immediately  stop Work under the
                Contract; and

                Paragraph  17.1.C  within  fifteen  (15)  Days  after  receiving
                written  notice of request to pay such  amounts  Hughes shall be
                entitled to (without any further notice to Customer):

                (i)   immediately  sell all the work in progress  and retain the
                      proceeds of such sale; and

                (ii)  the  provisions  of Paragraph  17.1.F(2)  shall apply with
                      respect to the resale of the Launch Services and refund to
                      Customer of the proceeds realized therefrom.

            (4) If  Customer  pays the amounts  specified  in  Paragraph  17.1.C
                within  fifteen  (15) days  after  receiving  written  notice of
                request to pay such amounts, then

                (i)   title  to  all  items  of  Work  which   would  have  been
                      incorporated  into a deliverable  item under the Contract,
                      shall,  subject to  applicable  United  States  Government
                      export  regulations,  vest in  Customer,  and Hughes shall
                      deliver all such items to Customer  FOB Hughes  plant,  El
                      Segundo, California (who shall accept such items); and

                                      -72-

<PAGE>


                (ii)  the  provisions of Paragraph  17.1.F(2),  shall apply with
                      respect  to resale of the  Launch  Services  and refund to
                      Customer of the proceeds realized therefrom.

      E.    Except as specified in this Paragraph  17.3, or Paragraphs 4.6, 4.8,
            4.9, 4.14,  4.16,  4.19 or 32.4,  Hughes shall not have the right to
            terminate or suspend the Contract.

17.4  Should  Customer  become a debtor in any bankruptcy  proceeding,  Customer
      shall move to assume or reject the Contract  within  forty-five  (45) days
      after the entry of an order for relief.

17.5  Customer may, upon written notice to Hughes,  terminate immediately all of
      the Contract if the aggregate of Excusable  Delays (except those Excusable
      Delays  caused by  Customer's  failure to perform  its  obligations  under
      Article 29) exceeds  twelve (12)  months.  If Customer so  terminates  the
      Contract,  Hughes shall refund to Customer all amounts  (including amounts
      paid under the ATP) paid to Hughes  pursuant to the Contract less a profit
      of twelve and one half percent (12.5%) on such amounts, provided, however,
      such   profit   shall   not   exceed   [                                 ]*

17.6  Hughes shall use reasonable  efforts to place  Subcontracts  on terms that
      will enable Hughes to terminate in a manner  consistent  with this Article
      17.

17.7  Because time is of the essence in the Contract,  any disputes  between the
      Parties  under  Article  17 will be decided  by an  expedited  arbitration
      procedure.

ARTICLE 18. DATA AND SOFTWARE

18.1  Use of Contract Deliverable Data and Documentation

      Subject  to  the  provisions  of  Article  21  (Proprietary  Information),
      Customer and its Consultants shall have a nonexclusive,  non-transferable,

      actual  physical  operational  lifetime  of the  Satellite,  the  Contract
      Deliverable  Data and  Documentation  for the  Orion 3  Satellite  Program
      solely for  purposes  of  maintaining  and  operating  the  Satellite  and
      delivered Satellite Control Equipment and Ground Control Software.

18.2  Use of Copyrights

      Notwithstanding  any other  provision  hereof,  the ownership and title to

      physical  operational  lifetime  of the  Satellite  to make  copies of the
      Contract  Deliverable Data and Documentation  solely for use in connection
      with  the  maintenance  and  operation  of  the  Satellite  and  delivered
      Satellite  Control   Equipment  and  Ground  Control   Software.   On  all
      documentation  that is  copyrighted,  Customer shall apply the appropriate
      copyright  notice to all copies made thereof.  All rights to documentation
      not owned by Hughes  are  limited  by the  extent of  Hughes'  rights  and
      interests therein.

18.3  Software Rights in Ground Control Software

      Hughes grants to Customer a  non-exclusive,  non-transferable  license and
      worldwide,  royalty-free,  fully  paid-up  right for the  actual  physical

      Except  for  those  rights in the  Ground  Control  Software  specifically
      granted in the  Contract,  no rights in the Ground  Control  Software  are
      granted to Customer.  The Ground Control  Software in source code form and

ARTICLE 19. PATENT INDEMNIFICATION

19.1  In lieu of any other warranty by Customer or Hughes  against  infringement
      of intellectual  property  rights,  express or implied,  it is agreed that
      Hughes will indemnify and defend (including by way of settlement),  at its
      expense, any suit against Customer based on a claim that Customer's use of
      the Satellite,  Satellite  Control  Equipment,  Ground  Control  Software,
      Contract  Deliverable Data or  Documentation  furnished under the Contract
      infringes an intellectual property right in the country of delivery or the
      United States,  unless such  infringement  occurred  solely as a result of
      Customer's provision of designs, specifications or instructions to Hughes,
      and  provided  Hughes is  promptly  notified  in writing of such claim and
      given  authority,  information  and  assistance  by  Customer,  at Hughes'
      expense,  for the  defense or  settlement  thereof.  Hughes  agrees to pay
      damages and costs awarded against  Customer in any suit defended by Hughes
      pursuant to the Contract.

      Nothing in the Contract shall be construed as requiring Hughes to defend a
      suit or pay  damages  or costs if  either  (i) the  infringement  claim or
      judgment  is based  upon the use of any goods and  services  furnished  in
      combination  with  other  goods and  services  not  provided  by Hughes or
      approved for use by Hughes,  if the  infringement  would not have occurred
      but for such  combined use;  (ii) the  infringement  claim is based on the
      goods and  services  being used in other than  their  specified  operating
      environment;  or (iii)  the  infringement  claim  is  based on  Customer's
      modification of the Satellite, Satellite Control Equipment, Ground Control
      Software, Contract Deliverable Data or Documentation.

      If the  use of  the  Satellite(s),  Satellite  Control  Equipment,  Ground
      Control Software,  Contract  Deliverable Data or Documentation is enjoined
      in such suit, Hughes shall, at its option, either procure for Customer the
      right to use the Satellite(s), Satellite Control Equipment, Ground Control
      Software, Contract Deliverable Data or Documentation,  as the case may be,
      or substitute an equivalent product  reasonably  acceptable to Customer or
      modify the same to render them  noninfringing.  If Hughes  determines that
      none of these  


                                      -76-

<PAGE>



      alternatives are reasonably available or feasible,  Hughes shall meet with
      Customer to address the matter and reach an equitable solution  reasonably
      acceptable to Customer.

      If the infringement  results solely from Customer's  provision of designs,
      specifications  or  instructions  to Hughes,  Customer will  indemnify and
      defend  (including by way of  settlement),  at its expense,  any such suit
      against Hughes,  provided  Customer is promptly notified in writing of the
      claim of infringement and given  authority,  information and assistance by
      Hughes, at Customer's expense, for the defense or settlement thereof.

19.2  Each  Party's  total  liability  for the cost of any such  defense and any
      subsequent  award of damages  and costs  under  this  Article 19 shall not
      exceed Ten Million  Dollars  (U.S.  $10,000,000).  The existence of one or
      more claims or lawsuits shall not extend this amount under patent covering
      combination of items furnished hereunder with other devices or elements.

19.3  In no event shall Hughes be liable for any lost revenues, lost profits, or
      other indirect,  incidental,  special or consequential damages suffered by
      Customer (as contrasted with damages  suffered by any third party claiming
      infringement of its intellectual property rights under this Article 19 for
      which  Customer  may  become  liable) as a result of a claim or suit under
      this Article 19.

19.4  The foregoing  constitutes the Parties' entire  obligation with respect to
      claims for infringement.

ARTICLE 20. RIGHTS IN INVENTIONS

20.1


      A.    As  used  in  the  Contract,  "Program  Invention"  shall  mean  any
            invention,  discovery or improvement  conceived of and first reduced
            to  practice  in the  performance  of the Work  under the  Contract.
            Information  relating  to  Program  Inventions  shall be  treated as
            proprietary  information  in accordance  with the  provisions of the
            Contract.  Rights to  inventions  conceived  solely by Hughes or its
            employees shall vest completely with Hughes.

      B.    Hughes shall be the owner of all Program Inventions  invented solely
            by Hughes.  Hughes grants  Customer a fully  paid-up,  royalty-free,
            nonexclusive license for the actual physical operational lifetime of
            the Satellite in Program Inventions to use Program Inventions solely
            for the purposes of  maintenance  and operation of the Satellite and
            any other item delivered that contains Program Inventions.

      C.    The  following  shall apply to joint  Program  Inventions:  that is,
            inventions  conceived  jointly  by one or  more  employees  of  both
            Parties hereto:

            (1) each Party shall have an equal,  undivided  one-half interest in
                and to  such  joint  Program  Inventions,  as  well as in and to
                patent applications and patents thereon in all countries.

            (2) Hughes  shall have the first  right of  election  to file patent
                applications  in any country,  and Customer  shall have a second
                right of election. Each Party in turn shall make its election at
                the earliest  practicable time, and shall notify the other Party
                of its decision.

            (3) The  expenses  for  preparing,  filing and  securing  each joint
                Program  Invention patent  application,  and for issuance of the
                respective patent shall be borne by the Party which prepares and
                files the application.  The other Party shall furnish the filing
                Party  with  all  documents  or  other  assistance  


                                      -78-

<PAGE>


                that may be  necessary  for the filing and  prosecution  of each
                application.  Where such joint Program Invention application for
                patent is filed by either Party in a country which  requires the
                payment of taxes,  annuities,  maintenance fees or other charges
                on a pending application or on an issued patent, the Party which
                files the application shall, prior to filing,  request the other
                Party to indicate  whether it will agree to pay one-half of such
                taxes,  annuities,  maintenance fees or other charges. If within
                sixty (60) Days of receiving such request,  the non-filing Party
                fails  to  assume  in  writing   the   obligation   to  pay  its
                proportionate share of such taxes,  annuities,  maintenance fees
                or other  charges,  or if  either  Party  subsequently  fails to
                continue  such  payments  within  sixty (60) Days of demand,  it
                shall  forthwith  relinquish to the other Party,  providing that
                said other Party  continues such payments,  its interest in such
                application  and patent  and the  Invention  disclosed  therein,
                subject, however, to retention of a irrevocable,  fully paid-up,
                non-exclusive,   non-assignable   license   in   favor   of  the
                relinquishing  Party, its parent,  and any subsidiary thereof to
                make,  use, lease and sell  apparatus  and/or methods under said
                application and patent.

      D.    Each owner of a jointly-owned patent application or patent resulting
            therefrom   shall,   provided  that  it  shall  have  fulfilled  its
            obligation,   if  any,  to  pay  its  share  of  taxes,   annuities,
            maintenance  fees and other charges on such pending  application  or
            patent,  have the right to grant  non-exclusive  licenses thereunder
            and to retain any consideration that it may receive therefor without
            obligation  to account  therefor to the other Party.  In  connection
            therewith,  each of the Parties  hereby  consents to the granting of
            such  non-exclusive  licenses by the other Party and also agrees not
            to assert any claim  with  respect to the  licensed  application  or
            patent against any licensee of the other Party thereunder during the
            term of any such license.

20.2  No sale or lease  hereunder  shall  convey  any  license  by  implication,
      estoppel or otherwise,  under any  proprietary or patent rights of Hughes,
      to practice any process with such

ARTICLE 21. PROPRIETARY INFORMATION

21.1  Under the Contract,  Hughes (and its Affiliates) and Customer may disclose
      to each other such of their respective  information,  some of which may be
      Proprietary  Information as defined below, as the disclosing  Party in its
      sole  discretion  believes  will be  essential  to the  objectives  of the
      Contract and which it has a right to disclose. Any information required by
      the Contract to be set forth in Contract Deliverable Data or Documentation
      shall be deemed essential to the objectives of the Contract.

21.2  "Proprietary   Information"   means   information   which  a  Party  deems
      proprietary  to it. Each Party shall hold in confidence  and withhold from
      third  parties  any and all  Proprietary  Information  received  under the
      Contract and shall use such  Proprietary  Information only as set forth in
      the Contract and for no other purpose  unless the  disclosing  Party shall
      otherwise  agree  in  writing.   Each  Party  shall  take  reasonable  and
      appropriate  measures to safeguard any  Proprietary  Information  received
      under the Contract from theft, loss or disclosure to others,  and to limit
      access  to  Proprietary  Information  to  those  officers,  directors  and
      employees within the receiving Party's organization who reasonably require
      access  in  order  to  accomplish  the  aforesaid  purposes.   Proprietary
      Information shall be in written or other permanent form and be prominently
      identified as proprietary  using an appropriate  legend,  marking stamp or
      other clear and conspicuous  written  identification  which  unambiguously
      indicates  the  information  being  provided  is the  originating  Party's
      Proprietary  Information.  Any such  information  in other than written or

      originating  Party's  Proprietary  Information  at the  time  of  original
      disclosure  and  thereafter  summarized  in written form which clearly and
      conspicuously identifies the Proprietary  Information.  Such summary shall
      be  transmitted  by the  originating  Party to the receiving  Party within
      thirty (30) Days of the nonwritten disclosure.

21.3  The receiving  Party shall not be liable for use or disclosure of any such
      Proprietary Information if it can establish that the same:

                                      -81-



<PAGE>


      A.    Is or becomes a part of the public  knowledge or literature  without
            breach of the Contract by the receiving Party; or

      B.    Is known to the receiving  Party without  restriction  as to further
            disclosure when received; or

      C.    Is independently developed by the receiving Party as demonstrated by
            written records; or

      D.    Becomes  known to the  receiving  Party from a third party who had a
            lawful right to disclose it and without breach of the Contract.

      Specific  Proprietary  Information  shall not be deemed to be available to
      the public or in the  possession of the receiving  Party merely because it
      is embraced by more general  information  so available or in the receiving
      Party's possession.

21.4  Should  the  receiving  Party be faced  with  judicial  or  administrative
      governmental   action  to  disclose   Proprietary   Information   received
      hereunder,  said receiving  Party shall  forthwith  notify the originating
      Party in sufficient  time to permit the  disclosing  Party to intervene in
      response to such action.

21.5  The receiving Party agrees promptly to notify the disclosing  Party of the
      loss or unauthorized use or disclosure of any Proprietary Information, and
      upon request of the originating Party, the receiving Party shall surrender
      any part or all of the Proprietary Information to the originating Party.

21.6  The  individuals  identified in Article 24 (Notices) are designated as the
      point for receiving Proprietary  Information exchanged between the Parties
      pursuant to the Contract.

21.7  Hughes  shall  have its  Subcontractors  agree in  writing  to be bound to
      protect Customer's  Proprietary  Information on the same conditions as set
      forth herein.

                                      -82-

21.8  Customer  shall  have  its  Consultants  agree in  writing  to be bound to
      protect Hughes Proprietary Information on the same conditions as set forth
      herein.

21.9  Upon  termination of the Contract for any reason,  the Parties shall cease
      use of all Proprietary Information furnished by the other Party and shall,
      at the direction of the  furnishing  Party,  return to or destroy all such
      Proprietary  Information,  together  with all copies  made  thereof.  Upon
      request,  the  receiving  Party shall send the other  Party a  destruction
      certificate.

21.10 Customer and Parent acknowledge that Hughes would be irreparably harmed if
      any  competitor  of Hughes  as  determined  by  Hughes  in its  reasonable
      discretion  were to acquire  access to any of the  intellectual  property,
      Proprietary  Information or other technology,  data or inventions  covered
      under the Contract (collectively, the "Intellectual Property"), regardless
      of whether such  competitor has an ownership  interest in Customer or ONS.
      Accordingly,  Customer and ONS agree that no competitor of Hughes shall be
      given  access to any of the  Intellectual  Property and that should such a
      competitor  obtain  control of  Customer  or  otherwise  be an assignee or
      transferee of Customer  with regard to the  Contract,  Hughes may take any
      and all  reasonable  steps  to  safeguard  and  protect  its  Intellectual
      Property.   Notwithstanding  any  provisions  of  the  Contract  requiring
      arbitration,  the  foregoing  agreement  may be  enforced by Hughes by the
      entry of injunctive relief, in addition to all other remedies available to
      Hughes under the Contract,  applicable law or otherwise. The provisions of
      this Paragraph 21.10 shall apply mutually to the Intellectual  Property of
      Customer and ONS

21.11 Notwithstanding any provision of this Contract, the Parties agree that the
      existing Non-Disclosure Agreement between the Parties shall remain in full
      force and effect according to its terms.

      change or price adjustment, if any, or both, Hughes shall proceed with the
      performance of the Contract, as unchanged.

      Customer  shall  request  Hughes to proceed  with the changes and Customer
      will pay the  offered  price and accept the revised  Delivery  Schedule or
      performance  specifications  pending any  decision to the  contrary  under

ARTICLE 28. CORRECTIVE MEASURES IN UNLAUNCHED SATELLITES

28.1  Notwithstanding  Paragraph  28.4 and without  limiting the  obligations of
      Hughes under other provisions of the Contract,  if the data available from
      an HS 601 HP or HS 601  satellite  model  shows  that  there is a material
      deficiency in the design or manufacture  of such satellite  model that, in
      the  opinion  of  Hughes,  could  adversely  affect  one or  both  of such
      satellite  models,  Hughes  shall  notify  Customer  of any such  material
      deficiency  coming to Hughes'  attention and shall,  promptly upon written
      request of Customer,  take appropriate corrective measures to the Work, at
      Hughes' own expense, with respect to the Satellite so as to eliminate from
      the Satellite all the material deficiencies  discovered in the Satellite's
      model.

      which  the  Satellite  will be  subjected  in  orbit,  Hughes  shall  take
      corrective  measures as Hughes  deems  appropriate  in  consultation  with
      Customer.

28.3  If Hughes,  in accordance with this Article_28,  replaces any equipment or
      any part which was determined to be deficient, such deficient equipment or
      part shall remain or become the property of Hughes.

      satellites owned by others.

      be applicable.

30.2  If,  during the course of  performance  or  non-performance  hereunder,  a
      dispute arises between Customer and Hughes as to the rights or obligations
      of either Party under the Contract (or resulting from an alleged breach of
      the Contract),  either Party may give written notice of its objections and
      the reasons therefor and may recommend corrective action.  Hughes' Program
      Manager  shall  consult with  Customer's  Program  Manager in an effort to

      and  conciliation,  or if neither  Party  desires to pursue  mediation and
      conciliation,  such dispute may be referred on the  application  of either
      Party for final  determination  to an  arbitration  tribunal  convened  in
      accordance  with  the  Commercial   Arbitration   Rules  of  the  American
      Arbitration  Association,  which  arbitration  shall be conducted by three

            (3) any decision by the arbitrators referred to shall be made within
                six  (6)  months  from  the  date  on  which  a  Party   demands
                arbitration  or within such extended  period as the  arbitrators
                may unanimously allow.

30.6  Except as  specifically  set forth in this  Article  30, the  election  of
      either Party to proceed with  arbitration  under this Article 30 shall not
      change the rights or obligations  of each Party as otherwise  stated under

      A.    Within  forty-five (45) Days  thereafter  submit a price proposal to
            Customer  outlining  a plan for  storage in the  Continental  United
            States,  including  transportation,  periodic  Satellite testing and
            maintenance of batteries; and

      B.    Specify  to  Customer  the  storage   arrangements   that  would  be
            acceptable to Hughes, including Hughes' storage terms.

      Upon agreement  between  Customer and Hughes as to Hughes'  proposal,  the
      Satellite and related equipment shall be delivered by Hughes to the agreed
      storage site, and the Contract shall be amended pursuant to Paragraph 22.3
      and Paragraph 35.5.

32.2  In the event  Customer gives Hughes less than six (6) months prior written
      notice of its desire to place the Satellite in storage,  Customer shall be
      obligated to reimburse Hughes for any nonrefundable deposits or reasonable
      expenses  actually  incurred  by  Hughes  (and  invoiced  to  Customer  in
      reasonable  detail)  (i) in order to  arrange  for  transportation  of the
      Satellite to the  Designated  Launch Site or (ii) to prepare the Satellite
      for Launch at the Designated Launch Site.

32.3  Six (6) months prior to the Scheduled Launch Date for a stored  Satellite,
      Customer shall, by notice in writing, order Hughes to remove the Satellite
      from  storage  and  deliver  the   Satellite  in  orbit   subject  to  the
      availability  of a Launch  Vehicle.  The cost of shipping of the Satellite
      and related  equipment from the storage facility to the Designated  Launch
      Site shall be borne by  Customer  to the extent such cost plus the cost of
      shipping the  Satellite  and related  equipment  from Hughes' plant to the

32.4  If a Satellite is Available  for  Shipment but (i) the  Designated  Launch
      Site is not  available or ready to receive  shipment of the  Satellite for
      whatever reasons (e.g.,  Beneficial  Access to the Designated  Launch Site
      has  not  been  provided)  and  (ii)  Customer  has not  provided  for the
      Satellite to be delivered  into storage in accordance  with the provisions
      of this  Article,  Hughes,  at its option,  may deliver the  Satellite and
      related  equipment into storage either at Hughes' own facilities or at the
      facilities  of a  third  party.  The  costs  of  storage,  transportation,
      periodic  Satellite  testing and  maintenance  of batteries as well as all
      other  reasonable  costs  associated  with such storage  shall be borne by

32.5  If a  Satellite  is  ordered  to be  launched  later  than six (6)  months
      following  its  Available  for Shipment  date for reasons not the fault of
      Hughes or any Affiliate or Subcontractor of Hughes, it is agreed that such
      Satellite shall, upon Hughes' request,  be returned at Customer's expense,

      the  Satellite,  Customer has caused the  Satellite to be  maintained in a
      storage environment suitable for prevention of deterioration,  and further
      provided  that said  Satellite has not been damaged while in storage or in
      transit.  In the event Customer  contracts with a third party to store the
      Satellite,  if such Satellite has not been properly maintained or has been
      damaged in storage or in transit,  the cost of repair of such disrepair or
      damage and all  transportation  and related  costs,  plus a twelve and one
      half  percent  (12.5%)  profit,  shall be borne and paid for by  Customer.
      Hughes may elect to perform inspection and refurbishment at the Designated

                subject  to  Article  7  (Permits   and   Licenses:   Government
                Approvals).  Hughes  shall  have no  liability  in the  event an
                export license is not issued for the benefit of Customer.

            (4) With respect to Launch Services, Customer shall notify Hughes in
                writing  whether it desires  to retain  the Launch  Services  or

                Hughes  within  eighteen  (18) months  after the initial  Launch
                Date. If Customer  desires to launch the  Satellite  within such
                eighteen  (18)  month   period,   then  Hughes  shall  use  best
                reasonable  efforts  to  arrange  with the  Launch  Provider  to
                provide Launch  Services  within such eighteen (18) month period

      D.    Launch Insurance.

            Upon Customer's request and in Customer's behalf, Hughes shall place
            Launch Insurance for the Satellite. The Parties acknowledge that the
            Delta  III  is a new  launch  vehicle.  Hughes  estimates  that  the
            insurance rate for the initial Delta III launch will be in the range
            of eighteen percent to twenty-one  percent (18% to 21%). The Parties
            understand  that Hughes cannot  guarantee its ability to obtain 

                                     -103-

            such  insurance at such rates (or any  insurance,  whether or not at
            commercially  reasonable  rates),  and  Hughes  shall  be  under  no
            liability to Customer or any third party  whatsoever for its failure
            to do so. In the event Hughes obtains Launch Insurance for Customer,
            Hughes  shall  provide  such  Launch  Insurance  to  Customer  on  a
            pass-through basis,  provided,  however, that (i) Hughes will not be
            obligated  to pay the  underwriters  of the Launch  Insurance  until
            after it has  received the premium  payment  from  Customer and (ii)
            Hughes   shall  be  entitled  to  a  payment  for  its  general  and
            administrative  costs in procuring the Launch Insurance,  such costs
            not to exceed two percent (2%) of the cost of the Launch Insurance.

      E.    Option Satellite

                  (1)      Hughes agrees to provide  Customer with an additional
                           satellite ("Option Satellite") of design identical to
                           the  Satellite,   which  Option  Satellite  shall  be
                           delivered in orbit within  nineteen (19) months after
                           order  for  One  Hundred  Eighty-Three  Million  U.S.
                           Dollars (U.S. $ 183,000,000).  This option is subject
                           to the following conditions:  (i) in no case will the
                           Option Satellite be launched earlier than April 1999;
                           (ii) design  changes in the Option  Satellite  may be
                           ordered  by  Customer  prior to  order of the  Option
                           Satellite,  said  changes  may  modify  the price and
                           change the delivery schedule; and (iii) the provision
                           of launch services for the Option  Satellite shall be
                           subject to the provisions of sub-paragraph (6) below.

                  (2)      In addition,  Customer may delay  ordering the Option
                           Satellite until fifteen (15) months prior to in-orbit
                           delivery;  provided (i) Customer places the order for

                  (6)      In the event Customer orders an Option Satellite as a
                           replacement Satellite for a failed launch,  McDonnell
                           Douglas  has  agreed to use best  efforts to launch a
                           replacement satellite within twelve (12) months after
                           such  failure,  subject  to its  obligation  to  give
                           priority to U.S.  government  launches.  In the event
                           Customer  orders  an Option  Satellite  that is not a
                           replacement   satellite,   Hughes   shall   use  best
                           reasonable  efforts  to  obtain  a Delta  III  launch
                           vehicle  meeting the above delivery  schedule for the
                           Option Satellite.  Where a Delta III is not available
                           and the Option Satellite is not a replacement for the
                           Satellite,  the  price  shall  be  adjusted  for  the

                           selected  launch  vehicle,  which  vehicle  shall  be
                           acceptable to Customer.

                  (7)      Hughes   shall   furnish  the  Option   Satellite  in
                           accordance  with the provisions of the documents that
                           constitute the Contract. Except as otherwise required
                           by the terms of this Paragraph  33.1.F,  the contract
                           terms for the Option  Satellite  will be identical to
                           the  Contract,   provided,   however,   the  delivery
                           schedule  shall be adjusted,  if  necessary,  for the
                           later timeframe of the Option  Satellite and the risk
                           elements (e.g.,  liquidated damages for late delivery
                           and performance  incentives) shall be adjusted to the
                           change in price from the Satellite so as to represent
                           the same percentage risk.

                   (8)     Where  Customer makes any payments for Payload and/or
                           Long-Lead Inventory Items but Customer fails to order
                           the  Option  Satellite  during  the  applicable  time
                           specified in this  Paragraph  33.1.F,  the option for
                           the Option Satellite shall no longer be effective and
                           Hughes shall deliver to Customer,  within thirty (30)
                           days after the  expiration  date of the  option,  the
                           Payload Long-Lead Inventory Items purchased with such
                           payments.

         Hughes will,  at  Customer's  direction,  modify the Ku Band 2 Repeater

         Hughes no later than thirty  (30) days after  Customer  exercises  this

         communications requirements set forth in Sections 3.3, 9.7, 8, and 9 of
         Exhibit B (Satellite  Technical  Specifications)  without degrading the
         performance  specified in Appendix A of Exhibit B (Satellite  Technical
         Specifications).1 This change will provide two (2) operating linearized
         channels  and one (1)  spare  linearized  channel.  The  price for this
         option, including hardware,  engineering,  testing, etc. is Two Million
         Two Hundred  Thousand U.S. Dollars (U.S.  $2,200,000).  For this price,
         Customer  may, in its  discretion,  choose  either of the following two
         options:

                  (1)      The  addition of Hughes  [                          ]*
                           [           ] to the Ku-Band 2 Repeater Transponders.*
                           This  addition  will  increase  the  dry  mass of the
                           Satellite by [ ], and cause a corresponding reduction*
                           in the Operational  Lifetime of the Satellite of five
                           (5) months.  This addition will have no impact on the
                           Scheduled Delivery Date of the Satellite ; or

                  (2)      The   replacement  of  the  existing  [             ]*
                           [             ] in each  Transponder of the Ku-Band 2*
                           Repeater  with a single  linearized  amplifier  unit.
                           This  change  will  have no impact on the dry mass or
                           Operational Lifetime of the Satellite, but will delay
                           the delivery of the Satellite two (2) months.

         Customer must exercise this option no later than January 31, 1997.

         [         ] and  one (1) set of SCE at  Customer's  site in  Rockville,*
         Maryland.  Currently,  the [   ] site is designated as the primary TT&C*
         site and primary  Satellite  Control Facility and the Rockville site is
         designated as the backup Satellite Control Facility.  Provided Customer
         notifies Hughes by June 15, 1997,  Customer may change the primary TT&C
         and primary Satellite Control Facility site designations from the [   ]*
         site to a site  specified  by  Customer.  The  Parties  agree  that the
         performance  of the command  link will need to be  reanalyzed  if it is
         relocated  from  [       ].  The Parties  further agree that a possible*
         result  of such  analyses  may be  changes  to  Exhibits  B  (Technical
         Specifications) and E (Ground Segment).

         Parties shall amend the Contract in accordance  with  Paragraph 35.5 as
         soon as is reasonably possible after option exercise to incorporate the
         schedule  adjustments,  price  adjustments  (which shall be  considered
         Progress Payments,  time-phased  accordingly,  and incorporated into an
         amended  Exhibit  F as  appropriate),  and  changes  to  the  technical
         exhibits  and  other  Contract  terms  and  conditions  which  are made
         necessary by such exercise.

                  officers,  employees,  agents  or  servants  of  any  law of a

         Program.

         Communications International, Inc. (the "Orion 3 Contract")

Ladies and Gentlemen:
                           This  certificate  is delivered to you in  connection
                  with the Orion 3 Contract.  Each  capitalized term used herein

                  thereto in the Orion 3 Contract. We hereby certify,  after due
                  inquiry, that as of the date hereof:

                  Hughes'  performance  of the Work is such that  Hughes will be
                  able to Deliver the Satellite in accordance  with the Delivery

Schedule 15.4

                  In October 1995,  Skydata  Corporation  ("Skydata"),  a former
contractor,  filed suit against Orion Atlantic,  Orion Satellite Corporation and
Orion,  in the United States  District Court for the Middle District of Florida,
claiming  that certain  Orion  Atlantic  Operations  using frame relay  switches
infringe  a Skydata  patent.  Skydata's  suit  sought  damages  in excess of $10
million and asked that any damages  assessed be trebled.  On December  11, 1995,
the Orion  parties  filed a motion to dismiss the lawsuit on the grounds of lack
of jurisdiction and violation of a mandatory arbitration agreement. In addition,
on December 19, 1995, the Orion parties filed a Demand for  Arbitration  against
Skydata  with  the  American  Arbitration   Association  in  Atlanta,   Georgia,
requesting   damages  in  excess  of  $100,000   for  breach  of  contract   and
declarations,   among  other  things,  that  Orion  and  Orion  Atlantic  own  a
royalty-free license to the patent, that the patent is invalid and unenforceable
and that Orion and Orion Atlantic have not infringed on the patent.  On March 5,
1996, the court granted the Company's motion to dismiss the lawsuit on the basis
that Skydata's claims are subject to arbitration. Skydata appealed the dismissal
to the United States Court of Appeals to the Federal Circuit. Skydata also filed
a counterclaim in the arbitration  proceedings  asserting a claim for $2 million
damages as a result of the conduct of Orion and its affiliates. On May 15, 1996,
the  arbitrator  granted the Orion  parties'  request for an initial  hearing on
claims  relating  to the Orion  parties'  rights to the  patent,  including  the
co-ownership  claim and other  contractual  claims.  This  initial  hearing  was
scheduled to take place in November 1996.

                  On November 9, 1996,  Orion and Skydata executed a letter with
respect to the settlement in full of the pending litigation and arbitration.  As
part of the  settlement,  the  parties  are to release all claims by either side
relating in any way to the patent and/or the pending litigation and arbitration.
In addition,  Skydata is to grant Orion (and its  affiliates)  an  unrestricted,
word-wide  paid-up  license to make,  have made, use or sell products or methods
under the patent and all other corresponding  consideration and reissue patents.
Orion  is to pay  Skydata  $437,000  over a period  of two  years as part of the
settlement.  The  parties  are in the  process of  documenting  the terms of the
settlement in a formal settlement agreement.
