   * 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.

                           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.

                     BE CONSIDERED BY PROSPECTIVE INVESTORS.

                                 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.

 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

 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 entered into an agreement with
British  Aerospace to acquire 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")  which will close
prior to or concurrently with the Offering.     

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 an authorization to proceed with
Hughes Space and Communications  International,  Inc. ("Hughes Space") for Orion
3,  commenced  construction  of  Orion 3 in  mid-December  1996 and  expects  to
conclude a satellite  procurement  contract for Orion 3 by mid-January 1997 (the
"Orion 3 Satellite  Contract").  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.

                            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. See "Description of Notes -- Security."

Optional Redemption         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. See  "Description  of Notes --
                            Optional 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 Indebtedness." 

Ranking                     The  indebtedness  evidenced  by the  Notes  and the
                            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
                            Guarantees)  outstanding,  all of which  would  have
                            been senior 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.
    

Certain Covenants           The  Senior  Notes   Indenture   and  the  Indenture
                            relating to the Senior  Discount  Notes (the "Senior
                            Discount  Notes  Indenture"  and  collectively,  the
                            "Indentures")  will contain certain covenants which,
                            among other things,  will restrict  distributions to
                            stockholders  of  the  Company,  the  repurchase  of
                            equity  interests  in the  Company and the making of
                            certain other  investments and restricted  payments,
                            the  incurrence  of additional  indebtedness  by the
                            Company  and  its   restricted   subsidiaries,   the
                            creation  of certain  liens,  certain  asset  sales,
                            transactions  with  affiliates and related  parties,
                            and mergers and consolidations.  See "Description of

(1)  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  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,  $9.8  million,  $1.0  million,  $1.0  million  and $7.3  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 $105.4  million and $70.5
     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  $107.1  million for the year ended
     December 31, 1995 and $71.8 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 cash represents the estimated $72 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. The actual amount to be
     placed  in escrow  and  reflected  as  restricted  cash will  depend on the
     interest rate on the Senior Notes and 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.

LIMITED OPERATIONS; HISTORY OF LOSSES AND NEGATIVE EBITDA; EXPECTATION OF
FUTURE LOSSES

   
   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 $103.2 million and $67.3 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 $426 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  $72  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 $50.6
million and $39.5 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 assets
pledged to secured  indebtedness will be available to satisfy obligations of the
secured debt before

                                       16

<PAGE>



   
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.

   
   Orion may have to change launch vehicles if, for example, one of its selected
vehicles  experiences a launch failure with respect to another satellite.  Orion
intends to order  certain  long lead time parts in order to reduce the amount of
time needed to obtain one replacement satellite. However, 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
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

                                       17

<PAGE>



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.

   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

                                       18

<PAGE>



   
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."     

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

                                19

<PAGE>



   
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.

   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."     

                                20

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 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     

                                21

<PAGE>



   
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.
    

                                22

<PAGE>



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 8.1 million shares or approximately 40% of the Orion
voting  stock that will be  outstanding  after the  Transactions  (12.0  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 -- Certain  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  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

                                23

<PAGE>



   
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 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  --
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 121,988
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  121,988  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 $332 million.  Other than the amounts 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 $6 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.   See   "Certain
Transactions."  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 are the sources and uses of funds in the  Transactions,  assuming a
Closing Date of January 30, 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.

            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 $332 million,  net of
estimated  financing costs of approximately $15 million.  Of the $347 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 $72 million will be placed in an escrow account to fund
the first six scheduled  interest  payments on the Senior Notes. Such amount has
been  reflected as  restricted  cash.  The actual  amount  placed in escrow will
depend on the interest rate on the Senior Notes and on market  interest rates 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.  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.

  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 $1.3  million in  interest
expense for the nine months ended  September  30, 1996.  The amount of pro forma
interest  expense  with  respect  to the  Notes  does  not  give  effect  to any
allocation of the gross proceeds of the Offering between the Notes and Warrants.
Because a portion of the gross  proceeds will be allocated to the Warrants,  the
discount on the Notes resulting therefrom will be accreted into interest expense
(using the interest method) over the term of the Notes.
    

3. Elimination of minority interest as a result of the Exchange.

$2.5 million and the  amortization  of excess cost over fair value of net assets
acquired of $1.7 million resulting from the acquisition of the Limited Partners'

  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 $1.7  million in  interest
expense for the year ended  December 31, 1995.  The amount of pro forma interest
expense with respect to the Notes does not give effect to any  allocation of the
gross proceeds of the Offering between the Notes and Warrants. Because a portion
of the gross  proceeds  will be allocated to the  Warrants,  the discount on the
Notes  resulting  therefrom  will be accreted into interest  expense  (using the
interest method) over the term of the Notes.
    

3. Elimination of minority interest as a result of the Exchange.

   
4. To record the dividend  requirement on the Series C Preferred Stock issued as
a result of the Exchange as well as pro rata accretion to redemption  value over
a 25-year period.
    

5. Pro forma weighted average shares outstanding for the year ended December 31,

             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.

(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 $105.4 million and $70.5 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  $107.1  million for the year ended  December 31,
     1995 and $71.8 million for the nine months ended September 30, 1996.

         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 $11.6 million for the first nine months of
1996 compared to $4.8 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 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 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 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 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

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

                                44

<PAGE>



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 an authorization to proceed 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.

 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  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.

   
   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 trans

                                54

<PAGE>



mission 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.

   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.

                                55
    

<PAGE>



   
   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.

</TABLE>

   More  than  half of  Orion's  customers  are  based in the  U.S.,  but  these
customers have a substantial  majority of their points of service in Western and
Eastern Europe, as indicated in the chart below.


                                   [GRAPHIC]


   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  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, de

                                57

<PAGE>



   
pending 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  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

                                58

<PAGE>



   
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 because 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

                                59

<PAGE>



   
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.

   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

                                63

<PAGE>



   
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.  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' 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."

   
   For a  discussion  of Orion's  financing  needs with  respect to Orion 3, see
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations  -- Liquidity  and Capital  Resources"  and "Risk Factors -- Need for
Substantial Additional Capital" and "Risk Factors -- Launch of Orion 2 and Orion
3 Subject to Significant  Uncertainties -- Substantial Financing  Requirements."

   The proposed coverage of Orion 3 is shown below.

   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 2%. 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 proposed 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  --  Satellite  Risks --  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 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     

                                68

<PAGE>



   
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 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     

                                69

<PAGE>



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.  Ascent's  Appraisal  Memorandum for Orion 1 (the "Ascent
Memorandum"),  a copy of which has been filed as an exhibit to the  Registration
Statement  of  which  this  Prospectus  is a part,  sets  forth  other  material
assumptions, information,  qualifications and limitations upon liability related
to Ascent's  appraisal.  The  foregoing  description  of Ascent's  appraisal  is
qualified in its entirety by reference to the Ascent Memorandum.

   
   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.

   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.  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 recogni
    

                                70

<PAGE>



   
tion 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 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
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.     

                                71

<PAGE>



   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  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.

                                72

<PAGE>



   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.  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

                                73

<PAGE>



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 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
    

                                74

<PAGE>



   
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 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.

                                75

<PAGE>



   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.

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.
    

STOCK OPTION PLANS

   1987  Employee  Stock  Option  Plan.  In April 1987,  Orion  adopted its 1987
Employee  Stock  Option Plan.  Under the 1987  Employee  Stock  Option Plan,  as
amended in March  1995,  options to  purchase up to an  aggregate  of  1,470,588
shares of Common Stock may be granted to key employees of Orion and its

                                84

<PAGE>



subsidiaries. The 1987 Employee Stock Option Plan provides for the grant both of
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.

*    Less than 1%.

(1)  In accordance with Rule 13d-3 under the Exchange Act, a person is deemed to
     be a "beneficial  owner" of a security if he or she has or shares the power
     to vote or direct  the voting of such  security  or the power to dispose or
     direct the  disposition of such  security.  A person is also deemed to be a
     beneficial  owner of any  securities  of which that person has the right to
     acquire  beneficial  ownership within 60 days from September 30, 1996. More
     than  one  person  may be  deemed  to be a  beneficial  owner  of the  same
     securities.  All  persons  shown in the table  above  have sole  voting and
     investment power, except as otherwise indicated. This table includes shares
     of Common Stock subject to outstanding  options granted pursuant to Orion's
     Stock Option Plan and the  Non-Employee  Director  Stock  Option Plan.  The
     shares held by the Limited  Partners and their  affiliates may be deemed to
     be  beneficially  owned  by  their  parent  companies,   including  British
     Aerospace Public Limited Company, COM DEV, Limited, Kingston Communications
     (Hull)  plc,  Martin  Marietta  Technologies,   Inc.  and  Lockheed  Martin
     Corporation, Matra Hachette and Nissho Iwai Corporation.     

(2)  For the purpose of computing the  percentage  ownership of each  beneficial
     owner,  any securities which were not outstanding but which were subject to
     options,  warrants, rights or conversion privileges held by such beneficial
     owner  exercisable  within  60  days  were  deemed  to  be  outstanding  in
     determining  the  percentage  owned by such  person  but  were  not  deemed
     outstanding in determining the percentage owned by any other person.

   
(3)  Includes  511,678 shares held of record and 86,505 shares issuable upon the
     exercise of warrants held by British  Aerospace  Space  Systems,  Inc. Such

discretion  shall  deem to be fair  and  appropriate;  provided  that no Note of
$1,000 in principal amount at maturity or less shall be redeemed in part. If any
Note is to be redeemed in part only,  the notice of redemption  relating to such

redeemed.  A new Note in principal  amount at maturity  equal to the  unredeemed
portion  thereof  will  be  issued  in the  name  of  the  Holder  thereof  upon
cancellation of the original Note.

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

                                97
    

<PAGE>



   
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 $72 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   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
Note   Guarantees   will  be  effectively   subordinated  to  all  such  secured
indebtedness to the extent of the collateral therefor.

refinanced  is  subordinated  in  right  of  payment  to the  Notes  or the Note
Guarantees, such new Indebtedness, by its terms or by the terms of any agreement
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

fluctuations in foreign currency exchange rates or interest rates and (b) do not
increase the Indebtedness of the obligor outstanding at any time other than as a
result of fluctuations in foreign  currency  exchange rates or interest rates or
by reason of fees,  indemnities  and  compensation  payable  thereunder  and (C)
arising from agreements  providing for  indemnification,  adjustment of purchase
price or similar  obligations,  or from Guarantees or letters of credit,  surety
bonds or performance bonds securing any obligations of the Company or any of its
Restricted  Subsidiaries  pursuant to such  agreements,  in any case Incurred in
connection with the disposition of any business, assets or Restricted Subsidiary

promptly (A) used to purchase  Notes  tendered in an Offer to Purchase made as a
result of a Change in Control or (B) deposited to defease the Notes as described
below  under  "Defeasance";  (vi)  Guarantees  of the  Notes and  Guarantees  of

Indebtedness  of the Company  not to exceed,  at any one time  outstanding,  two
times the Net Cash Proceeds  received by the Company after the Closing Date from
the issuance and sale of its Capital Stock (other than Disqualified  Stock) to a
Person that is not a Subsidiary of the Company (less the amount of such proceeds
applied as provided in clause  (C)(2) of the first  paragraph or clause (iii) or
(iv) of the second paragraph of the "Limitation on Restricted Payments" covenant
described  below);  provided that such Indebtedness does not mature prior to the
Stated Maturity of the Notes and has an Average Life longer than the Notes;  and
(ix) Redemption Indebtedness.

   (b)  Notwithstanding any other provision of this "Limitation on Indebtedness"
covenant,  the maximum amount of  Indebtedness  that the Company or a Restricted
Subsidiary may incur  pursuant to this  "Limitation  on  Indebtedness"  covenant
shall  not  be  deemed  to  be  exceeded,   with  respect  to  any   outstanding
Indebtedness,  due solely to the result of fluctuations in the exchange rates of
currencies.

   (c) For purposes of determining any particular  amount of Indebtedness  under
this "Limitation on Indebtedness" covenant, (1) Guarantees, Liens or obligations
with respect to letters of credit supporting  Indebtedness otherwise included in
the  determination  of such particular  amount shall not be included and (2) any
Liens granted  pursuant to the equal and ratable  provisions  referred to in the
"Limitation  on  Liens"  covenant  described  below  shall  not  be  treated  as
Indebtedness.  For purposes of determining  compliance with this  "Limitation on
Indebtedness"  covenant,  in the event  that an item of  Indebtedness  meets the
criteria of more than one of the types of  Indebtedness  described  in the above
clauses,  the  Company,  in its sole  discretion,  shall  classify  such item of
Indebtedness  and  only be  required  to  include  the  amount  and type of such
Indebtedness in one of such clauses.

   (d) In the event that the Company or any  Restricted  Subsidiary  shall repay
any  Indebtedness  (other  than the  Notes)  pursuant  to  clause  (i)(A) of the
"Limitation on Asset Sales" covenant, the aggregate amount of Indebtedness which
may  otherwise  be  Incurred  under  clauses  (i)(B)  and  (viii) of the  second
paragraph of paragraph  (a) of this  covenant  shall be reduced by the amount of
such repayment.  The Company shall designate how much of such reduction shall be
applied to each such clause.

sinking fund obligation,  principal  installment or final maturity,  in any case
due within  one year of the date of  acquisition)  or (iv) make any  Investment,
other than a Permitted Investment, in any

Company or a Restricted  Subsidiary to an Unrestricted  Subsidiary) accrued on a
cumulative basis during the period (taken as one accounting period) beginning on

case except to 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

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

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

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

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

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

the Common Stock of which has been issued or sold  pursuant to this clause (iv),
be the owner of a satellite.

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 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.

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  enter into, renew or extend any transaction (including,

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

prohibited  by  the  "Limitation  on  Restricted  Payments"  covenant  or  (vii)

representation  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

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

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.

of the Company or its Restricted  Subsidiaries  created in favor of the Holders;

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,

   The  Company  will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  enter into any sale-leaseback transaction involving any

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

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
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

                               115
    

<PAGE>



   
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.

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 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.

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

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
having  jurisdiction  in the premises enters a decree or order for (A) relief in
respect of the  Company,  any  Guarantor  or any  Significant  Subsidiary  in an
involuntary  case under any applicable  bankruptcy,  insolvency or other similar
law now or  hereafter  in effect,  (B)  appointment  of a receiver,  liquidator,
assignee,  custodian,  trustee, sequestrator or similar official of the Company,
any Guarantor or any Significant  Subsidiary or for all or substantially  all of
the  property  and  assets of the  Company,  any  Guarantor  or any  Significant
Subsidiary or (C) the winding up or liquidation of the affairs of the Company or
any Significant  Subsidiary and, in each case, such decree or order shall remain
unstayed and in effect for a period of 30 consecutive days; (h) the Company, any

described in paragraph  (i),  (j),  (k),  (l), (m) or (n) of Section 18.1 of the

   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

                               117
    

<PAGE>



   
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;
(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 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

                               119
    

<PAGE>



   
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.

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

                               120
    

<PAGE>



   
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 , as warrant agent (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  Stock,  (iii) the  issuance of Common  Stock or of
rights, options or warrants entitling the holder to

                               122

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 the  Current  Market  Price  per share  (as  defined  in the  Warrant
Agreement) 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

   In the opinion of Hogan & Hartson  L.L.P.,  tax counsel to the  Company,  the
following discussion summarizes,  subject to the limitation 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.

   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
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

                               126

<PAGE>



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. 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.

                               127

<PAGE>



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 expected,  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
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.

                               128

<PAGE>



   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,
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

                               129

<PAGE>



   
percentage points. For January 1997, the long-term AFR is 6.66% and the mid-term
AFR is 6.21% (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.

   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.

                               130

<PAGE>



   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.

NON-U.S. HOLDERS

THE NOTES

   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  connected
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.

                               131

<PAGE>



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
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

                               132

<PAGE>



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.

                         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.

                       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.

                                           ==============  ====================

   
   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.

   The  Underwriters  propose  to offer  part of the Units to the  public at the
Price to Public  set forth on the cover page of this  Prospectus  and in part to
certain  securities  dealers at such price less a concession  not in excess of $
and $ with  respect to Senior  Notes  Units and  Senior  Discount  Notes  Units,
respectively.  The  Underwriters  may allow,  and such  dealers may  reallow,  a
concession  not in excess of $ and $ with  respect to the Senior Notes Units and
Senior Discount Notes Units,  respectively to certain brokers and dealers. 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.

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

("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,

               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.

                                                               ERNST & YOUNG LLP

                  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:

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:

         Revenues from unaffiliated customers

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.

RECLASSIFICATIONS

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.

and 1994 follows:

   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.

Total interest (including commitment fees and amortization of deferred financing
costs)  incurred for the years ended December 31, 1995, 1994 and 1993 was $26.0,
$27.0,  and  $16.3  million,  respectively.  Substantially  all of the  interest
incurred in 1994 and 1993 has been capitalized, while approximately $1.3 million
of interest was capitalized in 1995.

   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
Orion has pledged its investment in the common stock of OrionSat and its limited
partner ownership interest to the Banks.

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.

   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

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.

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, OAP 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 $222 million of Units  consisting  of Senior  Notes,  due 2007 and
warrants to purchase  common  stock,  and an  aggregate of $125 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

   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.

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

or officer of another  enterprise),  against  expenses,  liabilities  and losses
(including attorney's fees), judgments,  fines and amounts paid or to be paid in

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)

under Section 174 of the Delaware  Code for approval of an unlawful  dividend or

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

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
Incorporation  provides  that OrionNet  Finance  Corporation's  directors  would
remain  subject to liability  for  monetary  damages (i) for any breach of their

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

provision  also does not affect a  director's  responsibilities  under any other
laws,  such as the  federal  securities  laws or state or federal  environmental

   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,

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 pur

                              II-5

              INFORMATION NOT REQUIRED IN PROSPECTUS (Continued)

chase 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 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.

                                   PART II
              INFORMATION NOT REQUIRED IN PROSPECTUS (Continued)

   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 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 $3.0
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.

   The financial  statements  filed as part of this  Registration  Statement are
listed in the Index to Financial Statements on page F-1.

   (2) Schedules

   The financial  statement  schedules of the Company have been omitted  because
the  information  required to be set forth therein is not applicable or is shown

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.
