* 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 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.

         Interest on the Senior Notes will be payable  semi-annually  in cash on
_________  and ________  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").

         The shares of Common Stock of Orion initially issuable upon exercise of
all the Warrants would  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) and the application of the proceeds thereof, as
of September 30, 1996, the Company would have had $84.9 million of  indebtedness
(other  than  the  Notes)   outstanding,   including  $24.9  million  of  senior
indebtedness  ($7.2  million of which would have been secured) and $60.0 million
of 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) and no subordinated indebtedness.  The Notes and the Guarantees will be
effectively  subordinated  to such  secured  indebtedness  to the  extent of the
collateral therefor.

                                   The Company

Overview

                  Orion  is  a  rapidly  growing  provider  of   satellite-based
communications  services,   focused  primarily  on  (i)  private  communications
networks,  (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  and Internet  Service  Providers  ("ISPs")  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 providers.
The Company provides its services directly to customer premises using very small
aperture terminals ("VSATs").

                  The Company  commenced  operations of the Orion 1 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.,
Colgate-Palmolive,  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.  Through arrangements with 30 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.  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 believes that demand for  international  satellite
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  


                                      -4-

<PAGE>


U.S., (iv) increased size and scope of television programming distribution,  (v)
worldwide  deregulation  of  telecommunications  markets,  and  (vi)  continuing
technological advancements.  The Company is well positioned to take advantage of
growth and foreign  investment in  developing  economies  (e.g.,  in Central and
Eastern  Europe,  Latin  America  and  Asia).  The  Company is able to provide a
variety of bandwidth  intensive  services to customers  doing  business in areas
with underdeveloped infrastructure on a reliable and cost efficient basis. Orion
also is well positioned to carry Internet traffic from the U.S. to Europe, Latin
America and Asia.

The Orion Strategy

         Orion's  strategy is to provide basic satellite  transmission  services
while focusing on delivery of value-added  private network services to end users
to maximize  its  revenues  per  transponder.  Orion's  strategy is based on the
following elements:

         o  Focus  on   Specialized   Communications   Needs  of   Multinational
Organizations.  Orion  targets  the  needs of  multinational  organizations  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, video  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.

         o Bridge to  Emerging  Markets  and  Remote  Locations.  Orion  targets
customers doing business in emerging  markets and remote  locations of developed
markets which 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  sends and
receives  transmissions  directly  to  and  from  customers  at  their  specific
locations.  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.

         o 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
terrestrial  facilities.  In  addition,  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.

         o 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  estimates  that  when  Orion  2 and  Orion 3 are  deployed,  the
satellite   footprints  in  the  aggregate  will  cover  an  area  inhabited  by
approximately 75% of the world's population.

         o Early Market Entry;  Local  Presence.  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. Orion has arrangements  with 30 local ground  operators  covering
most  countries  within the Orion 1  footprint.  These ground  operators  obtain
necessary  licenses,  install and  maintain  the  networks,  provide  in-country
business experience and often facilitate market entry.

         o Ownership of Facilities. Orion believes it is strategically important
to own its satellite facilities.  Orion believes that the ownership of satellite
facilities  provides  a cost  advantage  over  the long  term,  and  allows  the
satellites  to be designed to fit the  Company's  business  plan.  The Company's
satellite  ownership  enables it to 


                                      -5-

<PAGE>



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.

The Orion Satellite System

                  Orion provides an integrated  package of services to customers
through its  satellite,  its satellite  control  center and its network of local
ground operators.

                  The Company  launched Orion 1, a high-power  satellite with 34
Ku-band transponders, in November of 1994. Orion 1 covers 34 European countries,
much of the United States and parts of Canada, Mexico and North Africa.

                  The   Company   has   recently   signed  a  contract   and  an
authorization  to proceed  for the  construction  and  launch of two  additional
satellites, Orion 2 and Orion 3, respectively, and has commenced construction of
Orion 3. 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.  Orion 2 will increase  significantly  the  Company's  pan-European
capacity, the area of strongest demand in the Company's current operations.  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.

                  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. 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 approximately 75% of the world's population.

                  Orion  1  is  controlled   through  the  Company's   tracking,
telemetry  and  command  ("TT&C")  facility  in  Virginia.  Orion 2 will also be
controlled through this facility and Orion 3 will be controlled through a leased
facility in the Asia Pacific region.

                  The Company has arrangements  with 30 local ground  operators,
covering 27  European  countries,  portions  of the United  States and a limited
number of Latin  American  countries.  These  ground  operators  are critical to
providing  integrated  service,  because they obtain  necessary  local licenses,
install and maintain network equipment,  provide in-country  business experience
and often facilitate  market entry. The Company will expand its network of local
ground  operators to cover the areas within the  footprints of Orion 2 and Orion
3.

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 of  approximately  $426 million 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. Orion 1 commenced
commercial  operations  in January  1995 and the  Company  completed  an initial
public offering in August 1995.

                               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 U.S.
Federal  Communications  Commission ("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 $38 million
of obligations  of Orion  Atlantic to Limited  Partners in return for 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 British Aerospace Public Limited Company ("British  Aerospace"),  who will be
the largest  beneficial  owner of Orion Common Stock following the  Transactions
(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  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 an affiliate of British Aerospace to acquire the only outstanding
minority  interest  in Orion Asia  Pacific  (the  entity  with rights to certain
orbital slots) for  approximately  86,000 shares of Orion Common Stock (the "OAP
Acquisition").

Orion 2 and Orion 3 Contracts

                  Orion 2 and Orion 3 Construction Contracts.  Orion has entered
into a satellite  procurement contract with Matra Marconi Space for Orion 2 (the
"Orion 2  Satellite  Contract").  Orion has  entered  into 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 the customer 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 May
1999).  Payments  are  subject  to refund  pending  the  successful  launch  and
commencement of commercial operation of Orion 3. 

The Offering

                  The  offering  of  Units  made  hereby  (the   "Offering")  is
conditioned  on  consummation  of the Merger (as defined  below),  the Exchange,
repayment of the Orion 1 Credit  Facility  with proceeds of the Offering and the
Debenture  Investments;  the Exchange is conditioned on, among other things, the
approval of the Orion stockholders,  which will occur prior to the Offering. The

(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 statement of operations  data, on January 1, 1995
     and, in the case of balance sheet data, on September 30, 1996.
(2)  Computed on the basis  described for net loss per common share in Note 2 to
     the Consolidated Financial Statements.
(3)  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

                                      -12-

<PAGE>

     consummation of the  Transactions,  earnings would not have been sufficient
     to cover fixed  charges by $101.6  million  and $66.0  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  deficiencies  of  earnings  to cover  fixed  charges  of
     approximately $103.2 million for the year ended December 31, 1995 and $67.2
     million for the nine months ended September 30, 1996.
(4)  Backlog  represents  future revenues under  contract.  See "Risk Factors --
     Uncertainties Related to Backlog."
(5)  Points of service  includes  installed  VSATs and  additional  transmission
     destinations (such as customer premises) that share a VSAT.
(6)  "EBITDA" represents  earnings before minority  interests,  interest income,
     interest expense, net of 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 generally accepted  accounting  principles  ("GAAP").  EBITDA is not a
     measurement  under GAAP and may not be comparable to other similarly titled
     measures of other companies.
(7)  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  rates on the  Senior  Notes  and  interest  rates  on  government
     securities on the Closing Date.
(8)  Represents  amounts invested by Limited Partners (net of syndication  costs
     related to the investments),  adjusted for those 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 May 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 satellites  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   approximately  75%  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; and 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 $99.4  million  and $62.8  million  for 1995 and the nine
months ended September 30, 1996,  respectively.  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.  Accordingly,
Orion  expects to continue to incur net losses and to continue to have  negative
cash flow  (after  payments  for  capital  expenditures  and  interest)  for the
foreseeable  future.  The Company's  negative cash flow has been substantial and
net losses and negative  cash flows 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.
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 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.  Of this amount,  $3 million was
paid in the fourth  quarter of 1996,  and Orion is required to make  payments of
approximately $90 million,  $360 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), 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 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.
However,  there can be no assurance that these amounts will not be substantially
higher.  The Company believes these costs can be 


                                      -16-

<PAGE>



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
Orion in the Matra Marconi Investment.

                  Further,  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.
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.

Substantial Leverage; Secured Indebtedness

                  As of September 30, 1996, after giving pro forma effect to the
Transactions,  Orion  would have had  approximately  $401  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.  Given the  Company's  limited cash flow  available to service its
indebtedness,  such  additional  indebtedness  may be zero coupon or  pre-funded
indebtedness,  which would substantially increase the Company's liabilities. The
Company will  deposit $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  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  adjusting  for the
Transactions, interest costs of $46.8 million and $35.0 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 "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.  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 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.

                  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 in the event of a downturn
in  its  business.  See  "Management's  Discussion  and  Analysis  of  Financial
Condition  and

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  experienced 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 replacement  satellites.  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 of 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 effect on Orion's ability to provide services to customers.  However,  in the
event that the currently  operating  component fails, Orion 1 would experience a
significant  loss of  usable  capacity.  In such  event,  while  Orion  would be
entitled  to  insurance  proceeds of  approximately  $47 million and could lease
replacement  capacity and function as a reseller  with respect to such  capacity
(at  substantially  reduced gross  margins),  the loss of capacity  would have a
material   adverse  effect  on  the  Company  on  its  ability  to  service  its
indebtedness,  including  the Notes,  and the value of the  Warrants  and Common
Stock.  See "Business --  Implementation  of the Orion Satellite System -- Orion
1."

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

                  Limited  Insurance for  Satellite  Launch and  Operation.  The
in-orbit  insurance of Orion 1 and the launch and in-orbit insurance for Orion 2
and Orion 3 will not protect the Company against business interruption,  loss or
delay of revenues and similar losses and may not fully reimburse the Company for
its  expenditures.  In addition,  such insurance  includes or can be expected to
include  certain  contract  terms,  exclusions,  deductibles and material change
conditions  that are customary in the  industry.  Accordingly,  an  unsuccessful
launch of Orion 2 or Orion 3 or any significant loss of performance with respect
to any of its  satellites  would have a material  adverse  effect on Orion,  its
ability to make payments on its indebtedness, including the Notes, and the value
of the Warrants 


                                      -18-

<PAGE>

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 the  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  and start-up
expenses,  are  presently  estimated  to be  approximately  $260 million and 275
million.  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 on the value of
the Warrants and the Common  Stock,  as discussed in more detail above under the
caption "-- Need for Substantial Additional Capital."

                  Timing Uncertainties.  Orion presently plans to launch Orion 2
in the second  quarter of 1999 and plans to launch Orion 3 in the fourth quarter
of 1998,  based  upon the  construction  and launch  schedules  set forth in the
satellite  contracts.  To meet these  schedules,  Orion must raise the financing
needed for payments to the satellite  manufacturers,  receive certain regulatory
approvals,  finalize  the  satellite  designs  and take other  necessary  steps.
Failure to meet the construction and launch schedules could increase the cost of
Orion 2 or Orion 3, requiring additional financing. See "-- Need for Substantial
Additional Capital -- Substantial  Financing  Requirements;  Risks of Commencing
Construction  Prior to  Completing  Financing."  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.  A  significant
delay in the delivery or launch of Orion 2 or Orion 3 also would have a material
adverse  effect on Orion's marketing plan for such satellites and 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, 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."

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 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. Orion believes that
certain of its indirect  sales channels in Europe have not met  expectations  in
1996,  and is  seeking  to  supplement  its  sales in  Europe  by  significantly
increasing its direct sales capabilities in Europe, particularly with respect to
sales of  private  communications  network  services.  However,  there can be no
assurance  that this will be  successful.  Sales of Orion's  services  generally
involve a long-term complex sales process. 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 being able 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  communications  networks (or 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 this process to continue as it continues to significantly
increase its sales force.  Furthermore,  the Company may from time to time enter
into joint ventures and acquire  complementary  businesses.  Such joint ventures
and acquired  businesses  would need to be  integrated  with the Company,  which
would  place an  additional  burden on the  Company's  internal  systems and its
ability to manage its  employees  and its  relationships  with its local  ground
operators.  In addition,  the Company's ability to attract new orders is subject
to substantial  variations from quarter to quarter.  If the Company fails either
to expand in accordance with its plans or to manage its growth effectively there
could be a material adverse effect on its business,  growth, financial condition
and results of operations,  its ability to service its  indebtedness,  including
the Notes, and the value of the Warrants and Common Stock.

Potential Adverse Effects of Competition

                  The  international   telecommunications   industry  is  highly
competitive.  In  providing  international  telecommunications  services,  Orion
competes with established satellite and other transmission facilities providers,
including INTELSAT, EUTELSAT, PanAmSat and consortia of major telephone carriers
operating undersea fiber optic cables. In addition,  Orion competes with certain
established  telephone  carriers,  such as AT&T, MCI,  Sprint,  British Telecom,
Cable & Wireless, Deutsche Telekom, France Telecom and Kokusai Denshin Denwa, as
well as resellers of satellite  capacity,  such as 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, and have financial resources, experience and marketing capabilities 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 larger  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 private  network  services.
For example, the recently announced merger involving MCI and British 



                                      -20-

<PAGE>


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  offset  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 commence  operations,  they will
substantially increase the capacity available for the provision of services that
compete with the Company's services.  Absent a corresponding increase in demand,
this new  capacity  can be expected to result in  significant  additional  price
reductions.  Continued price  reductions could have a material adverse effect on
Orion's  ability to service its  indebtedness,  including the Notes,  and on the
value of the Warrants and the Common Stock. See "Business -- Competition."

Approvals Needed; Regulation of Industry

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

                  Additional   Regulatory   Approvals  Needed.  The  launch  and
operation of Orion 2 and Orion 3 will require a number of additional  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.   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 none of
the other  requisite  approvals  has 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.  While such
approvals  generally  have not been  difficult  for  Orion to obtain in a timely
manner,  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

                                      -21-

<PAGE>


new licenses  obtained) at the  expiration of the license term,  there can be no
assurance of renewal. 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.  Any  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 this will be
achieved.  The Company has commenced  construction  of Orion 3 and will commence
construction of Orion 2 promptly  following the Closing Date,  which is prior to
completion of ITU coordination.  There can be no assurance that ITU coordination
will be completed. In the event that successful coordination cannot be achieved,
Orion may have to modify the satellite design for Orion 2 or Orion 3 in order to
minimize the extent of any potential interference with other proposed satellites
using those orbital locations or frequency bands. Any such  modifications  could
increase the cost or delay the launch of the satellites (if significant  changes
to the satellite are required) and may result in  limitations  on the use of one
or more  transponders  on Orion 2 or Orion 3, which  could  impact 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 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. 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. 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  contracts  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 $_____ 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.

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.  There can be no
assurance that such changes will not adversely  affect the prospects or proposed
operations or expenses of Orion.

Risks of Conducting International Business

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

Dependence of Orion on Key Personnel

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

Control of Orion by Principal Stockholders

                  Executive   officers,   directors  and  their  affiliates  are
expected  to  beneficially   own   approximately   [12.0]  million  shares,   or
approximately  [46]% of the  Common  Stock that will be  outstanding,  after the
Transactions on a fully diluted basis. As a result,  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 Series A 8% Cumulative  Redeemable  Convertible
Preferred Stock (the "Series A Preferred Stock") and approximately  $4.7 million
(including accrued dividends) in 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").  Certain rights granted by Orion
to holders of the Senior  Preferred  Stock could  adversely  affect Orion or the
rights of holders of Warrants or Common Stock.  In  particular,  such holders of
Senior  Preferred Stock have the right to require Orion to repurchase the shares
of Common Stock  received upon  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).  This right is  exercisable
with respect to one-third  of the Senior  Preferred  Stock (and any Common Stock
received upon the conversion thereof) in June 1999,  two-thirds of such stock in
June 2000 and all of such  stock in June 2001.  The  Indentures  will  contain a
covenant  which  restricts the ability of the Company to honor these  repurchase
obligations.  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.  The  Company  expects to issue  $122.0
million in Series C  Preferred  Stock  (assuming a closing of the Merger and the
Exchange as of January 30, 1997),  and the Company may seek to  repurchase  such
stock in the future.  The Indentures will contain a covenant which restricts the
Company's ability to repurchase such stock. 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 are scheduled to be
made until _______________, 2002.


                                      -23-

<PAGE>


                  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 a portion of the
OID  corresponding  to such excess (i) will not be  deductible by the Company at
any time and (ii) may be eligible for the dividends received deduction available
to  corporate  holders in certain  circumstances.  See  "Certain  United  States
Federal Income Tax Consequences"  for a more detailed  discussion of the federal
income tax consequences to purchasers of the Senior Discount Notes.

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

No Prior Public Market

                  There is no existing market for the Units,  Notes or Warrants,
and there can be no assurance as to the liquidity of any market that may develop
for the Units, Notes or Warrants;  the ability of holders of the Units, Notes or
Warrants to sell such  securities,  and the price at which such holders would be
able to sell such  securities  cannot  be  predicted.  If such a market  were to
develop,  such  securities  could  trade at prices that might be higher or 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 and
the  indenture  for the  Debenture  Investments  will  effectively  prohibit the
payment of dividends for the foreseeable future.

Potential Adverse Effect of Shares Eligible for Future Sale

                  Upon  completion  of the Merger and the  Exchange,  Orion will
have  approximately  25.9 million shares of Common Stock  outstanding on a fully
diluted basis. Approximately 14.5 million of these shares will initially be held
by the Company's current  stockholders and 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,  including  British  Aerospace,  will own the  remaining  11.4 million
shares, all of which would be deemed to be "restricted  securities" as that term
is defined in Rule 144,  promulgated  under the  Securities  Act.  However,  the
Limited  Partners  will  be  granted  certain  shelf,  demand  and  "piggy-back"
registration  rights  with  respect to the Common  Stock  issuable  to them upon
conversion,  including  having the Company  prepare and, as soon as  practicable
after 180 days from the  Closing  Date cause to be filed a "shelf"  registration
statement  which  covers  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  so that the  Limited
Partners  will be able to sell,  each quarter,  up to an  additional  25% of the
Common Stock issuable to them upon  conversion,  on a  


                                      -24-

non-cumulative  basis. 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  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." 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 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 up to  approximately  $426
million 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  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 approval and adoption by Orion stockholders of the Merger and
the Exchange,  and (e) the issuance of approximately $60 million of Orion junior
subordinated convertible debentures in the Debenture Investments.

                                 USE OF PROCEEDS

The Offering

                  The net proceeds of the Offering to the Company are  estimated
to be approximately $______ 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
$_________  million of accrued  interest and $_______  million of interest  rate
hedging costs related to the Orion 1 Credit Facility),  to pay accrued satellite
incentive fees, to pay amounts owing to STET, a former limited partner,  and for
working capital and other general corporate purposes.  The outstanding principal
and interest  amount under the Orion 1 Credit Facility at September 30, 1996 was
$210.4  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 approximately  $11.9 million  installment paid in
July 1996 to the two approximately $22.9 million semi-annual installments due in
2001 (and thereafter). See "Certain Transactions."

                  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.

(1)  To the extent that the Limited Partners make guarantee payments on or after
     January 30, 1997 to the Banks under their capacity  leases that support the
     Orion 1 Credit Facility,  the net proceeds from the sources indicated above
     will be used, to the extent not needed to make the other payments set forth
     above,  to repay the Limited  Partners  the amounts paid to the Banks on or
     after January 30, 1997.

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

(3)  Most of the $31 million of working capital, plus cash on hand and cash flow
     from operations, will need to be used primarily to make payments on Orion 2
     and Orion 3 and for VSATs and other capital expenditures.  The Company does
     not have a revolving  credit facility or other source of readily  available
     capital.

(1)  Restricted cash represents the estimated $72 million that will be placed in
     escrow on the closing  date to 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  rates
     on the Senior Notes and the interest rates on government  securities on the
     Closing Date.
(2)  Includes  current  portion of long term debt of $33.9 million  (actual) and
     $6.4 million  (pro forma).  
(3)  Of the $322  million  gross  proceeds  from  issuance of the Units  offered
     hereby,  $ million  has been  allocated  to the  Senior  Notes,  $ has been
     allocated  to Senior  Discount  Notes and $ million has been  allocated  to
     capital  in excess of par to  reflect  the  issuance  of the  Warrants.  No
     assurance  can be  given  that  the  value  allocated  to the  Warrants  is
     indicative of the price at which the Warrants may actually trade.
(4)  Represents amounts invested by Limited Partners other than the Company (net
     of  syndication  costs  related  to the  investments),  adjusted  for those
     Limited Partners' share of net losses.
(5)  Excludes  1,486,364  shares  issuable upon exercise of options and warrants

              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 rights to
receive an identical number of shares of New ONSI. In addition,  pursuant to the
Exchange, New ONSI will issue shares of Series C Cumulative Redeemable 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 would also acquire approximately $37.5 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 Salomon  Brothers Inc dated December 10,
1996. Such value has been allocated to Orion  Atlantic's  assets and liabilities
based on management's  best estimate of fair value.  Prior to the effective date
of the Exchange  transaction,  Orion Atlantic  anticipates  receipt of a current
valuation of its Orion 1 satellite. Differences between management's estimate of
the  fair  value of the  Orion 1  satellite  and the  amounts  specified  in the
anticipated satellite valuation could be material.

                  In  addition  to the  Merger and the  Exchange,  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 and  Exchange 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 the write-off of deferred  financing  fees and
interest rate hedge breakage costs associated with the Orion 1 Credit Facility),
(ii) the British Aerospace Investment, with gross proceeds of $50 million, (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  and  (v)  payments  of
approximately $3.9 million owed to STET, a former limited partner (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 $308 million, net of
     estimated financing costs of approximately $14 million. Of the $322 million
     of gross  proceeds  from the Offering,  $ has been  allocated to the Senior
     Notes,  $ to the  Senior  Discount  Notes and $ 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 such
     proceeds,  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  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 under the Orion 1 Credit  Facility,  the  write-off of  unamortized
     deferred  financing  costs of $11.2  million and the costs of breaking  the
     existing swap of $5.9 million, and the pro rata allocation of such costs to
     the minority interests of Orion Atlantic.

3.   To reflect (i) the estimated proceeds from the British Aerospace Investment
     of $49.8 million,  net of estimated  financing costs of $.25 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's corresponding  reinvestment of $10 million
     in junior  subordinated  convertible  debentures,  and  financing  costs of
     $50,000.

5.   To  reflect  the  repayment  of $3.5  million of  promissory  notes and $.4
     million of accrued  interest  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 Limited Partners' units
     in Orion  Atlantic  for Series C Preferred  Stock of Orion.  The  Preferred
     Stock has been  valued at  approximately  $94  million  based on a fairness
     opinion  prepared by Salomon  Brothers Inc dated December 10, 1996 using an
     underlying Orion 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.  The Company
     has  allocated the step up in basis of  approximately  $46.5 million to the
     Orion 1  satellite  based on an estimate  of its fair value  September  30,
     1996. Accumulated  depreciation of $27.8 million relating to the portion of
     the  satellite  fair  valued  has  been  offset  against  the  basis of the
     satellite.  Prior  to the  effective  date  of the  Exchange,  the  Company
     anticipates   receiving  a  appraisal  of  Orion  1.  Differences   between
     management's  estimate of the fair value of the Orion 1  satellite  and the
     amounts  specified  in  the  anticipated  fairness  opinion  and  satellite
     valuation could be material.

    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 $1.2 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 the

    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 $1.6 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.

              SELECTED CONSOLIDATED FINANCIAL AND OPERATIONAL DATA
                  (Dollars in thousands, except per share data)

                  The following  selected  consolidated  statement 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  statement 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
statement of operations and balance sheet data is 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.

           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  received 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.  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.  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  offset  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 net losses 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, 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  


                                      -40-

<PAGE>

Orion 2 and a more  substantial  increase  in costs  with Orion 3.  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 for 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
123 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.

                  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.

                  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.

                                      -41-
<PAGE>

                  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.

                  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.

                                      -42-

<PAGE>

                  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 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
$3 million will be paid in cash on the Closing Date) 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  $600,000) 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.  The Company's  cash
flows  will be  inadequate  to cover its cash  needs and the  Company  will seek
financing from outside sources. 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
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
$90 million, $360 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),
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 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 costs 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.

                                      -44-
<PAGE>


                  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
Orion in the Matra Marconi Investment.

                  Further,  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.
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 carry
forward 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,  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 this Offering, all losses will be allocated to Orion.

Effect of Inflation

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

Effect of Recently Issued Financial Accounting Standards

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

                  In October 1995 the FASB issued Statement No. 123,  Accounting
for Stock Based  Compensation  which is effective  for awards  after  January 1,
1996.  Orion has  elected to  continue  to follow  Accounting  Principles  Board
Opinion No. 25,  "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations  in  accounting  for its  employee  stock based award  programs,
because, the alternative fair value accounting provided for under FASB Statement
No. 123, requires use of option valuation models that were not developed for use
in valuing 

                                      -45-
<PAGE>


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
networks,  (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  and ISPs  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   providers.  The  Company  provides  its
services directly to customer premises using VSATs.

                  The Company  commenced  operations of the Orion 1 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.,
Colgate-Palmolive,  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.  Through arrangements with 30 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.  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,  net  of  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  international  satellite
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.  The
Company is well positioned to take advantage of growth and foreign investment in
developing  economies  (e.g., in Central and Eastern  Europe,  Latin America and
Asia). The Company is able to provide a variety of bandwidth  intensive services
to customers  doing business in areas with  underdeveloped  infrastructure  on a
reliable  and cost  efficient  basis.  Orion  also is well  positioned  to carry
Internet traffic from the U.S. to Europe, Latin America and Asia.

                  Features and Benefits

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

                                      -47-

<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
avoids "last mile" limitations. In addition,  terrestrial bypass allows Orion to
avoid the multiple in-country toll charges of terrestrial facilities and thereby
reduces cost.

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




                  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 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
smaller,  less expensive  earth station  equipment.  The  satellite'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.

                  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 30  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   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 more  detail in the
footprint  set forth below under the  caption  "--  Implementation  of the Orion
Satellite System -- Orion 2." Orion 2 will increase  significantly 


                                      -48-
<PAGE>


the  Company's  pan-European  capacity,  the  area of  strongest  demand  in the
Company's current operations. 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  signed an  authorization  to proceed
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 approximately 75% 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 the delivery of  value-added  private  network
services to end-users, 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.


                                      -49-

                  Bridge to Emerging Markets and Remote Locations

                  Orion targets customers doing business in emerging markets and
remote  locations  of developed  markets  which 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 at their
specific   locations,   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 terrestrial
facilities  by  bypassing  multiple  telecommunications  service  providers  and
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  approximately  75% 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  versus
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  ownership of satellite  facilities
provides a long-term 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  also 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 to 1/2 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 extensive 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  distinct  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.  As such,  satellites enable high speed
communications service where there is no 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  and other
satellites.  This  enables  satellites  to use  the  higher  broadcasting  power
necessary  to support  smaller,  low-cost  VSAT earth  stations and make 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  consulting  firm)  estimates  that overall data  networking
services revenues in Western Europe alone totaled  approximately $2.7 billion in
1996, which number revenues excludes revenues from such services as leased line,
frame relay and ATM. Data networking applications include:

                  o 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.

                  o 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.

                  o 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.

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

                  o 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.

                           (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  connectivity  and
                  fast,  reliable data transport.  Frame relay services  support
                  these  applications  and reduce the number and  complexity  of
                  commands  needed  to route  data,  reducing  the cost of fully
                  meshed  networks.  According  to a  1996  report  prepared  by
                  Vertical  Systems Group,  worldwide  revenues from frame relay
                  services were $830 million in 1995.  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.  Companies  attempting to
implement  client/server  architectures,  install wide bandwidth applications or
employ  Internet  and  intranet  solutions  are  often  unable  to do so  due to
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  international  satellite
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  offer a
                  solution  to  this   problem  by  providing   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  image-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 customers  premises often consists of copper
                  wire,  which  cannot  handle  many high speed  data  services.
                  Satellites are well positioned to take advantage of this trend
                  because  they cover sites in  underdeveloped  areas and bypass
                  "last mile" copper wire  facilities  that are unable to handle
                  high speed frame relay 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  frequently  unable  to  use
                  current-

                                      -53-

                  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.  They 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 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 into more
                  remote  locations.   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 a customer  location,  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. 

                                      -54-

<PAGE>


                  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
                  in 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  transmit
                  using CDV technology.

Orion Services

                  Orion   provides   international,    satellite-based   digital
communications   services   comprised  of:  (i)  private  network  services  for
multinational  business and governmental  customers,  (ii) Internet backbone and
access  services for Internet  service  providers and corporate  users 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  are  derived  from the sale of  satellite
capacity.  However, 62% of bookings for the nine months ended September 30, 1996
were from private  network and Internet  services.  The Company  believes  these
figures are  consistent  with its 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


                                      -55-

<PAGE>


leased line services have  constituted a majority of Orion's bookings of private
communications  network  services to date.  Customers  connect between three and
nine sites with data rates generally of 128 Kbps or greater.

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

              [Document contains a diagram of the customer network]

                  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 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 will enable networks to send both voice and data concurrently
and 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.

              [Document contains a diagram of the customer network]

                  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
check image processing,  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 512 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.  ISPs and content
providers  are looking for reliable,  wide  bandwidth  connections  which bypass
congested  Internet network  segments.  Orion's  transatlantic  capacity is well
suited for ISPs and companies in Europe  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 


                                      -56-
<PAGE>



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.

              [Document contains a diagram of the customer network]

                  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 Tier I ISPs, such as DIGEX and UUNet.

                  Multicast  Satellite-Based  Internet Services.  Orion recently
introduced  its  NetCast  service  which  allows  ISPs  or  corporate  users  to
significantly  reduce Internet  bandwidth and ground facility costs. The NetCast
service is based on an  asymmetric  architecture  which  couples wide  bandwidth
satellite  broadcasting with narrow bandwidth terrestrial links to the Internet.
Furthermore,  NetCast can provide a single channel that is shared among multiple
ISPs,  which can remove a  significant  amount of traffic  from ISP  terrestrial
networks.

         Video Distribution and Other Satellite Transmission Services

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

                           Video Services - Contribution: Orion's video services
                  include  "contribution," the long-distance  transport of video
                  signals  (usually  one or  more  television  channels)  to one
                  location. For example,  Viacom has purchased capacity on Orion
                  1 for the  purpose of  transmitting  video  material  from its
                  studio in New York to a  broadcast  facility  in London,  from
                  which  it  is  inserted  into   programming   and  rebroadcast
                  throughout 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 Koln. Orion provided 24 MHz of
                  transatlantic    transmission    capacity   service   allowing
                  transmission of RTL's programming in compressed  digital video
                  format.

<PAGE>



                           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.

Customers and Backlog

                  Customers.  As of September  30, 1996,  Orion had entered into
contracts  with 167 customers,  principally  large  multinational  corporations,
European  companies and  governmental  agencies.  These  entitles come from many
different industries,  including communications,  broadcasting,  Internet access
services,  manufacturing,  government,  banking and  finance,  energy,  lottery,
consumer distribution and publishing.  Selected customers from each service area
are set forth below.

                  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 charts below.

         [GRAPHIC OMITTED]


                  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

                                      -59-

<PAGE>

Orion  would  retain  the $10  million  paid)  if it  fails  to  obtain  certain
approvals.  Payments  are subject to refund if the leased  transponders  are not
launched  and in  service  by May  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 place Orion 3 in service by May 1999.

                  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 beyond 1997.  Orion has begun to receive
contract  renewals  under  expiring   contracts  (under  some  of  the  earliest
contracts,  which  were  entered  into in 1993).  The size of  contracts  varies
significantly,  depending on the amount of capacity required to provide service,
the  geographic  location  of the  network and other  services  provided.  As of
September 30, 1996, Orion had a VSAT installation backlog of 68.

                  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
(and such event may 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  in the near
future,  and accordingly the Company no longer  considers such contracts 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 $ 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 a price for its entire
network,  with generally  consistent  quality of service throughout the 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  


                                      -60-

<PAGE>


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

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

                  Direct Sales

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

                  Indirect Sales Channels

                  Representatives/Distributors.    Orion   has   entered    into
agreements for the marketing of its private  communications  network services in
the  United  Kingdom,  France,  Germany,   Austria,  Italy  and  other  European
countries.  These  agreements  call for sales,  marketing  and customer  support
services in specified  geographical areas,  generally on a non-exclusive  basis.
Generally,  the duration of these  agreements is three years.  Third party sales
representatives  receive  commissions  and fees for sales and  customer  support
services,  each of which are payable over the life of the customer  contracts to
which the representative's services relate and which are based upon the revenues
derived.  Sales  representatives  are  supervised by Orion sales  managers,  who
establish  marketing  strategies with the  representatives,  establish  pricing,
attend  certain sales calls,  develop  marketing  materials  and sales  training
tools,  coordinate joint efforts in promotional  events and provide  information
about Orion's  services.  Orion also provides  engineering  support to its sales
representatives.  Orion  provides  some of these  functions to support the sales
efforts of its distributors. Distributors purchase Orion's services at wholesale
prices and resell  those  services  to  customers  at prices  determined  by the
distributors.  Two  Limited  Partners  who serve as sales  representatives  (and
ground operators) are entitled to receive additional commissions under a "profit
sharing"  formula based on their overall  contribution to sales,  but no amounts
have been paid under such formula to date.  Orion  expects  that unless  Limited
Partners  sales  representatives  increase their sales  significantly,  payments
under the profit sharing arrangement will be minimal.

                  Major Carriers and Other  Wholesalers.  Orion has entered into
distributor resale  arrangements both with major carriers,  teleport  operators,
resellers and other  companies in the United States and  internationally.  These
distributors  typically  purchase  communications  network  services  from Orion
(primarily the Digital Link and Digital  Channelized Link and to some extent the
DirectNet  services)  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 its relationships with these and other carriers. 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  providing  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 Orion enters into a contract with a
customer,  Orion  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 to or
among  points in 27 European  countries,  the United  States and  certain  Latin
American  countries (which comprises  substantially  all of the countries within
the  coverage  area of  Orion  1).  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 their
VSAT  installations  for  customers,  profit  sharing  payments will be minimal.
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  or fails to  perform  as
expected, Orion's ability to offer private communications networks (or services)
will be  impaired.  See "Risk  Factors -- Risks  Relating to  Potential  Lack of
Market Acceptance and Demand; Ground Operations."

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 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  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

                                      -63-

<PAGE>


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.   In-orbit  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."

                  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 first generation of satellites reaches the
end of its useful life.

         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(Degree)  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).

                                      -64-

<PAGE>








  [Document contains a map of North America and Europe showing in shaded areas
                      the coverage footprint of Orion 1 ]
















                  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, 




                                      -65-
<PAGE>


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 and on Orion
Atlantic. See "Risk Factors -- Risks of Satellite Loss or Reduced Performance."

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

         Orion 2

                  Schedule and Footprint. Orion intends to launch Orion 2 in the
Atlantic  Ocean  region to  bolster  its  European  capacity  and to expand  its
coverage area in the Commonwealth of Independent States, Latin America and parts
of Africa. Orion 2 will be a high power Ku-band  communications  satellite which
will  contain  approximately  30  transponders  of 54 MHz  bandwidth.  Orion has
obtained  conditional  authorization  from  the  FCC  for  the  orbital  slot at
12(Degree)  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 25 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 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  Atlantic  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  Atlantic  would be entitled to receive a partial refund based on
calculations of Orion 2's performance capabilities. Finally, 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 


                                      -67-

<PAGE>



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" 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,
except as discussed above.

                  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(degree)  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

                  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  pending  the  successful  launch  and  commencement  of
commercial  operations of Orion 3. 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  successful
launches with a failure rate of %. 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 the option to purchase a replacement satellite to be
launched  within 15 months  after  Orion  places the order for  completion  of a
replacement  satellite.  The order for a replacement  satellite cannot be placed
earlier  than the launch of Orion 3. 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 the Orion 3 continues to
provide  service  after the  expiration  of its  operational  life,  the Orion 3
Satellite Contract provides for further incentive payments. 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, except as discussed
above.

                  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  Atlantic  has been  licensed  by the FCC and has
completed the coordination process with INTELSAT and interested  administrations
to operate Orion 1 in geostationary orbit at 37.5(degree) West longitude.

              Orion 2: OrionSat has obtained conditional  authorization from the
FCC for the  construction,  launch and operation of Orion 2 at  12(degree)  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(degree)  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  commence
consultation  with  INTELSAT for Orion 2, and  believes  that since there are no
INTELSAT  satellites  located adjacent to the 12(degree) 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(degree) 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(Degree)  East longitude  orbital slot, but some proposals for
adjacent  slots would be entitled to priority  over the proposal by the Republic
of the Marshall Islands with respect to 


                                      -70-
<PAGE>



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 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 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(degree)  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(degree)
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(Degree)
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.

                  In September 1995,  Orion filed  applications for authority to
construct, launch and operate Ka-band satellites at 78.0(degree) East longitude,
93.0(degree) West longitude,  and 83.0(degree) West longitude,  and an amendment
to its pending application to construct,  launch and operate a Ku-band satellite
at 127(degree) West longitude to add a Ka-band payload. In addition, Orion filed
an  application  to  construct,  launch  and  operate  a  Ka-band  satellite  at
47(degree)  West  longitude,  and an  application  to modify  its  authority  to
construct,  launch and operate a Ku-band  satellite at 47(degree) West longitude
to include a Ka-band  payload.  On November 9, 1996,  Orion filed an application
for authority to construct, launch and operate a Ka-band satellite at 12(degree)
West longitude.  In May 1996, the FCC assigned Ku-band orbital  locations for 33
U.S. companies, including two assigned to Orion at 78(Degree) East longitude and
126.5(Degree)  East  longitude,  and one to Orion  Atlantic at  47(Degree)  West
longitude.  At  approximately  the same time the FCC made ITU  filings for these
satellites.  The FCC order does not license  these  satellites,  and some of the
applications  to  use  the  orbital  assignments  are  subject  to  further  FCC
processing.  There are ongoing  negotiations  among the applicants  concerning a
consensual Ka-band orbital assignment plan to be submitted to the FCC to resolve
a  number  of  mutually  exclusive  orbital  assignment  requests.  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 


                                      -71-

<PAGE>



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

     _______________________________________  has  delivered an appraisal to the
Company  valuing Orion 1 at  approximately  $____  million as of [September  30,
1996].  In preparing this appraisal,  ___________  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.  ___________  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.
___________  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.  ___________ also noted that the most accurate way to value
Orion 1 would be to identify recent, closely comparable sales of transponders or
satellites serving similar markets. ___________ did not use this method since it
was unable to identify any closely  comparable sales.  However,  ___________ 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.  ___________  Appraisal  Memorandum  for  Orion 1 (the "
___________  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  ___________  appraisal.  The foregoing  description  of  ___________
appraisal  is  qualified  in  its  entirety  by  reference  to  the  ___________
Memorandum.

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


                                      -72-
<PAGE>

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  and marketing  capabilities
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 low earth orbit systems ("LEO") such
as Globalstar or Iridium, 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.

                                      -73-
<PAGE>

                  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,  or its successors  under
any restructuring  plan, can be expected to continue to dominate this market for
the foreseeable  future.  INTELSAT,  a consortium of approximately 138 countries
established by international treaty in 1964, owns and operates the largest fleet
of  commercial  geosynchronous  satellites  in the  world (25  satellites,  with
additional  satellites on order).  INTELSAT's  satellites have historically been
general  purpose,  lower-power  satellites  designed  to serve  large areas with
public telephone service  transmitted  between expensive gateway earth stations.
INTELSAT generally provides capacity directly to its signatories who then market
such capacity to their customers.  The availability of new services generally is
subject to the discretion of each  country's  signatory and INTELSAT is required
under its charter to set its pricing in order to achieve a fixed pre-tax  return
on  equity  that  is  established  from  time to time  by  INTELSAT's  board  of
governors.  INTELSAT is considering a restructuring  and it is expected that the
Intelsat Assembly of Parties will decide on a new structure for the organization
in 1997. Any restructuring of INTELSAT that increases its marketing  flexibility
could  materially  impact  Orion's  ability to compete in the market for private
satellite delivered services.

                  PanAmSat   currently   operates  four  satellites,   with  one
satellite  providing  coverage in each of the Atlantic  Ocean  region,  the Asia
Pacific  region and Indian  Ocean region (the fourth  covers the Atlantic  Ocean
region  but is near the end of its  useful  life).  These  satellites  primarily
provide  broadcasting  services,  such as  television  programming  and backhaul
operations.  PAS 3,  launched in January  1996,  with  coverage of the  Atlantic
Ocean,  is  expected  to  compete  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 that will provide coverage of
the U.S., Central America and Mexico in 1997, 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 the
Orion satellites.

                  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 late 1996 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 

                                      -74-

<PAGE>



and/or the proposed  footprints of Orion 2 and Orion 3. As these new  satellites
commence operations, they will substantially increase the capacity available for
sale in the company's markets.  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  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. See "Risk Factors -- Potential Adverse Effects of Competition."

         Terrestrial Capacity

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

                  European Facilities. Orion's services compete with terrestrial
telecommunications delivery services, which are being improved gradually through
the  build-out  of fiber  optic  networks  and a move  from  analog  to  digital
switching.   As  fiber  networks  and  digital  network  switching  become  more
prevalent,  the resulting improved and less expensive  terrestrial capacity that
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 observed in some jurisdictions 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), and the Republic of the Marshall  Islands  (through  which the Company
has  applied  for the Orion 3  orbital  slot),  (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.  While such approvals generally have
not been difficult for Orion to obtain in a timely manner, 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(degree)  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(degree)  West longitude for operation of Orion 2.
The  Orion 2  authorization  will not  become  final  until  Orion  completes  a
consultation with INTELSAT and demonstration to the FCC of its financial ability
to meet the costs of  construction,  the launch of its  satellite  and operating
expenses  for one year  following  launch.  Orion  has not yet met the  required
financial  qualifications  demonstration to the FCC. It is required to make such
showing within ninety (90) days after completion of INTELSAT  consultation,  and
accordingly  intends  to  commence  consultation  with  INTELSAT  after  it  has
completed  an  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(degree) 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,  and Orion 1 may be used for  non-switched
services in and between EUTELSAT signatory countries.  Additional  consultations
or other  approvals may be needed in  individual  countries for the use of small
VSATs.

                  Orion 2. Orion has not commenced  consultations  with INTELSAT
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  satellites  located adjacent to
the 12(degree) West longitude orbital slot, the INTELSAT  coordination 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(degree)  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 are  process  for  coordinating
orbital slots through the ITU is discussed  under the caption " -- Orbital Slots
- -- ITU Coordination Process."


                                      -76-


<PAGE>


                  Orion 1:  After  Orion 1  reached  its  orbital  position  and
commenced  operation,  the FCC has notified the ITU, and the orbital location of
37.5(degree)  West  longitude  was entered into the Master  Registry of 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(degree)  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 administration's  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(degree)  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(Degree) East longitude  orbital slot, but
some proposals by other  administrations for adjacent slots would be entitled to
effective  priority  over the proposal by the  Republic of the Marshall  Islands
with respect to possible interference. Orion believes, based upon its monitoring
of the  proposals  of other  administrations  and  information  in the  industry
regarding  their  progress,  that  none of the  administrations  with  effective
priority over the proposal by the Republic of the Marshall  Islands will be able
to  launch a  satellite  prior to launch  of Orion 3 to take  advantage  of such
priority.  Orion also believes that it can complete the ITU coordination process
for Orion 3 at 139(Degree)  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
January 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.  The Order will have no change in
the licensing of Orion's  orbital  positions at  37.5(degree)  West,  12(degree)
West, 47(degree) West longitude and 126(degree) East longitude (the orbital slot
at 139(degree)  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 

                                      -77-

<PAGE>


hand at the time of  application  or obtain a waiver of the  required  financial
demonstration.  There is no  assurance  that Orion  will be able to obtain  such
waiver.

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

                  International Regulation

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

                  Orion  provides  service using the licenses it obtains or that
are  obtained  by  local  ground   operators  or,  in  certain  cases,   through
customer-obtained  authorizations.  For example,  Orion's representatives in the
United  Kingdom  (Kingston  Communications),  France (Matra  Hachette),  Germany
(Nortel Dasa) and Italy (Telecom Italia) have licenses in such countries.  Orion
also has obtained  "landing  rights" through the INTELSAT treaty  (although each
INTELSAT  signatory  country  retains   sovereignty  over  the  transmission  of
satellite  signals  and  retains  the  right to object to the use of the Orion 1
satellite  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.  However,  unlike the  European  Union,  countries  in the Asia Pacific
Region  have  fairly  dissimilar  regulatory  structures.  Orion  may  therefore
encounter regulatory barriers and high marketing costs that cannot be quantified
at this point.  Laws and regulations  regulating  access to satellite systems in
some countries in the Pacific Region are unsettled,  and many of these countries
maintain  strict controls on the ability of any entity other than the PTT or the
government,  or in certain cases local  companies,  to operate  satellite  earth
station  facilities.  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, 6 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 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 



                                      -78-

<PAGE>



parties'  rights  to the  patent,  including  the  co-ownership  claim and other
contractual claims. This initial hearing was scheduled to take place in November
1996.

         On November 9, 1996,  Orion and Skydata  executed a letter with respect
to the settlement in full 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.

Background of Directors and Executive Officers

                  Information  with respect to the business  experience  and the
affiliations  of the  Directors  and  Executive  Officers  of Orion is set forth
below.

         Gustave M. Hauser has been Chairman of Orion since January 1996 and has
been a Director of Orion since December  1982.  Since 1983, he has been Chairman
and Chief Executive  Officer of Hauser  Communications,  Inc., an investment and
operating  firm   specializing   in  cable   television  and  other   electronic
communications.  From  1973 to 1983 he served as  Chairman  and Chief  Executive
Officer  of  Warner-Amex  Cable  Communications,  Inc.  (formerly  Warner  Cable

Auditing,  Corporate  Responsibility  and  Ethics  (the  "Audit  Committee"),  a
Committee on Human Resources and Compensation (the "Compensation Committee"), an
Executive Committee, a Finance Committee and a Nominating Committee.

                  The  Audit  Committee  is  comprised  of  Messrs.   Van  Degna
(chairman),  Hauser and Kahn. The Audit Committee examines and considers matters
relating to the financial affairs of Orion,  including  reviewing Orion's annual
financial  statements,  the  scope  of the  independent  annual  audit  and  the
independent  auditors'  letter to management  concerning  the  effectiveness  of
Orion's internal financial and accounting  controls.  From the time Orion became

"1995 Public Company Period"), the Audit Committee held one meeting.

                  The  Compensation  Committee is  comprised  of Messrs.  Brekka
(chairman),  French, Saeman and Van Degna. The Compensation  Committee considers
and makes recommendations to Orion's Board of Directors with respect to programs

recommendations  to Orion's  Board of  Directors  with  respect to  compensation
matters and policies  and employee  benefit and  incentive  plans and  exercises

Public Company Period,  the Compensation  Committee held two meetings.  Three of

meetings.

                  The Executive Committee is comprised of Messrs.  Hauser, Kahn,

number.

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, as amended,  Orion's directors
would  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  Code for approval of an unlawful
dividend  or  an  unlawful  stock  purchase  or  redemption  and  (iv)  for  any
transaction from which the director derived an improper personal  benefit.  This
provision  also does not affect a  director's  responsibilities  under any other
laws,  such as the  federal  securities  laws or state or federal  environmental
laws.

                  Orion'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  publicly  traded
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 its  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.

         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% will vest on
January 17, 1997 or earlier at the  discretion  of the Board,  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  certain  financing
transactions  (including  the  Offering).  Finally,  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
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 


                                      -87-

<PAGE>


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 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;  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  fifty one percent (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 Employee 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
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 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 



                                      -88-

<PAGE>




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 shall 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 one hundred  percent 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 (5)
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,  Orion had 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
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 


                                      -89-

<PAGE>



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 are 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 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.

<PAGE>


         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

                              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,  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 which $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 another Limited Partner
(Matra Hachette) serves as a ground operations  representative in France.  Orion
expects to pay 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 has paid these Limited Partners $1.9
million in 1995 and $1.9 million in 1994 for these  services.  See  "Business --
Sales  and  Marketing"  and  "Business  --  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).  These shares were reconveyed to Orion and
are held in treasury at a value of $0.  These shares are pledged as security for
British  Aerospace  Space  Systems,  Inc. in the event British  Aerospace  Space
Systems, Inc. is required to fund amounts under its guarantee and Orion does not
provide  reimbursement.  These  arrangements  will be  terminated on the Closing
Date.

                  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  


                                      -92-

<PAGE>



shares to affiliates of Directors) at a purchase price of $8.50 per share, Orion
issued  100,326  additional  shares to the Directors and affiliates of Directors
who purchased  Common Stock in December  1993.  In addition,  after Orion issued
Series A 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 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  Space
Systems/Loral  ("SS/L") whereby SS/L agreed to purchase 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.

                  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 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. 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.

                  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"),  including  $3.5 million in cash and $8
million in promissory  notes,  $8.0 million of which was still outstanding as of
September  30, 1996 and $3.5 million  (plus  accrued  interest of  approximately
$600,000)  of which  will be payable 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  $600,000) of which become
payable 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 and caused to be posted a $10 million  letter of credit to support such
indemnity. Such arrangements 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."

                  In December 1996,  Orion and the Limited Partners entered into
the  Exchange  Agreement  and the  Merger  Agreement.  See "The  Merger  and the
Exchange."

                  The net proceeds of the British  Aerospace  Investment,  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  and Orion 3 Satellite
Contract.

         The following table sets forth certain information regarding beneficial
ownership  of the  Company's  Common  Stock,  as of September  30, 1996,  and as

Security

                  The Senior  Notes  Indenture  will provide that on the Closing
Date,  the Company must  purchase and pledge to the Senior Notes Trustee for the
benefit of the Holders of the Senior Notes the Pledged Securities in such amount
as will be sufficient upon receipt of scheduled  interest and principal payments
of  such  securities,  in  the  opinion  of  a  nationally  recognized  firm  of
independent public accountants  selected by the Company,  to provide for payment
in full of the first six  scheduled  interest  payments due on the Senior Notes.
The Company expects to use  approximately $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 or the Guarantors,  respectively, and
senior in right of payment to all existing and future subordinated  indebtedness
of the Company or the Guarantors, respectively. After giving pro forma effect to
the  Transactions and the application of the proceeds  thereof,  as of September
30, 1996, the Company would have had $84.9 million of  indebtedness  (other than
the Notes)  outstanding,  including $24.9 million of senior  indebtedness  ($7.2
million of which  would have been  secured)  and $60.0  million of  subordinated
indebtedness, and the Guarantors,  collectively, would have had $24.9 million of
indebtedness  (other  than the Note  Guarantees)  outstanding,  including  $24.9
million of senior  indebtedness  ($7.2 million of which would have been secured)
and no subordinated indebtedness.  The Notes will be effectively subordinated to
all such secured indebtedness to the extent of the collateral therefor.

Certain Definitions

                  Set forth below is a summary of certain of the  defined  terms
used in the covenants and other provisions of the Indentures.  Reference is made

the amount  calculated  pursuant  to (i),  (ii),  (iii) or (iv) for each  $1,000
principal amount at maturity of Senior Discount Notes:

                  (i) if the  Specified  Date  occurs  on  one  or  more  of the
         following dates (each a "Semi-Annual Accrual Date"), the Accreted Value
         will  equal the  amount set forth  below for such  Semi-Annual  Accrual
         Date:

         Semi-Annual                                            Accreted

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

                  (iii) if the  Specified  Date occurs  between two  Semi-Annual

         such  Specified  Date and (b) an amount equal to the product of (1) the
         Accreted Value for the immediately  following  Semi-Annual Accrual Date
         less the  Accreted  Value  for the  immediately  preceding  Semi-Annual
         Accrual Date  multiplied  by (2) a fraction,  the numerator of which is
         the number of days from the immediately  preceding  Semi-Annual Accrual
         Date to the  Specified  Date,  using a 360-day  year of  twelve  30-day
         months, and the denominator of which is 180; or

                  (iv) if the Specified  Date occurs after the last  Semi-Annual

Subsidiary or such Asset Acquisition;  provided that Indebtedness of such Person
which is  redeemed,  defeased,  retired  or  otherwise  repaid at the time of or

                  Limitation on Indebtedness

                  (a) The  Company  will  not,  and will not  permit  any of its
Restricted  Subsidiaries  to, Incur any  Indebtedness  (other than the Notes and
Indebtedness  existing on the Closing Date); provided that the Company may Incur

Incurred  on or  prior  to [ , 199 ],  or [ ] to 1,  for  Indebtedness  Incurred

Subsidiary)  shall be deemed,  in each case, to constitute an Incurrence of such
Indebtedness  not permitted by this clause (ii);  (iii)  Indebtedness  issued in
exchange for, or the net proceeds of which are used to refinance or refund, then
outstanding Indebtedness,  other than Indebtedness Incurred under clause (i)(B),

Indebtedness,  by its  terms or by the  terms  of any  agreement  or  instrument
pursuant to which such new  Indebtedness is outstanding,  is expressly made pari
passu with, or  subordinate  in right of payment to, the remaining  Notes or the
Note  Guarantees,  as the  case  may be,  (B) in  case  the  Indebtedness  to be


                                     -112-

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

Indebtedness is at least equal to the remaining Average Life of the Indebtedness

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

of the Company for the purpose of financing  such  acquisition),  in a principal
amount not to exceed the gross proceeds  actually received by the Company or any
Restricted  Subsidiary in connection with such disposition;  (v) Indebtedness of
the  Company,  to the extent the net  proceeds  thereof are promptly (A) used to

"Defeasance"; (vi) Guarantees of the Notes and Guarantees of Indebtedness of the

Indebtedness  Incurred  to  finance  the cost  (including  the  cost of  design,

Restricted Subsidiary after the Closing Date; (viii) 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

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,

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

"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.

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 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

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).

Owned Restricted  Subsidiary;  (ii) issuances of director's qualifying shares or

Subsidiary  would no longer  constitute  a Restricted  Subsidiary,  provided any
Investment in such Person remaining after giving effect to such issuance or sale
would  have been  permitted  to be made  under  the  "Limitation  on  Restricted
Payments" covenant, if made on the date of such issuance or sale.

         Issuances of Guarantees by New Restricted Subsidiaries

                  The Company will provide to the Trustees, on the date that any
Person becomes a Restricted Subsidiary,  a supplemental indenture to each of the

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

Senior Discount Notes Indenture, as the case may be.

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 $[ ]
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 equal to or greater than
$ million,  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 the
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  


                                     -117-

<PAGE>

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. 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

                  At all times from and after March 31, 1997, whether or not the
Company is then required to file reports with the Commission,  the Company shall
file with the Commission  all such reports and other  information as it would be
required  to file  with the  Commission  by  Sections  13(a) or 15(d)  under the
Securities  Exchange Act of 1934 if it were subject  thereto.  The Company shall
supply  the  Trustees  and each  Holder  or shall  supply  to the  Trustees  for
forwarding  to each such Holder,  without  cost to such  Holder,  copies of such
reports and other information.

Events of Default

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


                                     -118-

an event  of  default  that has  caused  the  holder  thereof  to  declare  such
Indebtedness  to be due and  payable  prior  to its  Stated  Maturity  and  such
Indebtedness  has not been discharged in full or such  acceleration has not been
rescinded  or  annulled  within  30 days of such  acceleration  and/or  (II) the
failure to make a  principal  payment at the final (but not any  interim)  fixed
maturity and such defaulted payment shall not have been made, waived or extended
within 30 days of such  payment  default;  (f) any final  judgment or order (not
covered by insurance)  for the payment of money in excess of $[ ] 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  outstanding  and not paid or
discharged  against all such Persons to exceed $[ ] 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; or (h) the Company, any Guarantor or

Guarantee  shall  cease to be, or shall be asserted in writing by the Company or
any Guarantor not to be, in full force and effect or  enforceable  in accordance
with their respective terms.

                  If an  Event  of  Default  (other  than an  Event  of  Default
specified  in clause (g) or (h) above that occurs with  respect to the  Company)
occurs and is  continuing  under the  Indentures,  the  relevant  Trustee or the
Holders of at least 25% in aggregate  principal amount at maturity of the Senior
Notes or Senior Discount Notes, as the case may be, then outstanding, by written
notice  to the  Company  (and to the  Trustee  if such  notice  is  given by the
Holders),  may, and the relevant  Trustee at the request of such Holders  shall,
declare the principal amount (in the case of Senior Notes) or Accreted Value (in
the case of Senior Discount Notes) of, premium,  if any, and accrued interest on
such  Notes  to  be  immediately   due  and  payable.   Upon  a  declaration  of
acceleration,  such principal amount or Accreted Value of, premium,  if any, and
accrued  interest  shall  be  immediately  due and  payable.  In the  event of a
declaration of acceleration  because an Event of Default set forth in clause (e)
above has occurred and is continuing,  such declaration of acceleration shall be
automatically  rescinded  and annulled if the event of default  triggering  such
Event of  Default  pursuant  to  clause  (e) shall be  remedied  or cured by the
Company or the relevant  Guarantor or  Significant  Subsidiary  or waived by the
holders of the relevant  Indebtedness  within 60 days after the  declaration  of
acceleration  with respect thereto.  If an Event of Default  specified in clause
(g) or (h) above  occurs with respect to the Company,  the  principal  amount or
Accreted Value, as the case may be, of, premium, if any, and accrued interest on
the Notes then  outstanding  shall ipso facto become and be immediately  due and
payable without any declaration or other act on the part of the relevant Trustee
or any  Holder.  The  Holders  of at least a  majority  in  principal  amount at
maturity of the  outstanding  Notes by written  notice to the Company and to the
relevant  Trustee, 

                                     -119-

<PAGE>

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)  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) 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


                                     -120-
<PAGE>

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 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  


                                     -121-
<PAGE>

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  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 a creditor 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  (as  defined in the  Indentures),  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.

<PAGE>

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 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 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
(other than pursuant to adjustments provided in the Warrant Agreement).

Registration Requirements

                  The  Company  is  required,  under  the  terms of the  Warrant
Agreement,  to use  its  best  efforts  to  maintain  the  effectiveness  of the
Registration  Statement of which this  Prospectus is a part 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  

                                     -124-

<PAGE>

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.

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 Indenture 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.

                  Except in the limited circumstances  referred to below, owners
of beneficial  interests in Global  Securities will not be entitled to have such
Global Securities or any Units, Notes or Warrants represented thereby registered
in their names,  will not receive or be entitled to receive physical delivery of
Certificated  Securities  in exchange  therefor and will not be considered to be
the owners or holders of such Global Securities or any Units,  Notes or Warrants
represented  thereby for any purpose  under the Units,  Notes or Warrants or the
Indenture or the Warrant Agreement.

                  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 Indenture) 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 


                                     -125-
<PAGE>

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 Trustee by such date. As soon as possible thereafter,  the 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
Note as shown on the records of 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 in bearer form or registered in "street name," and
will be the  responsibility  of such  participants.  None  of the  Company,  the
Trustee,  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  date of such Unit. If a 


                                     -127-
<PAGE>



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.

         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  Note 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 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.

                                     -129-
<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 maximize 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 lower rate than ordinary
income for certain non-corporate taxpayers. The distinction between capital gain
or loss and  ordinary  income or loss is also  relevant  for  purposes of, among
other things, limitations on the deductibility of capital losses.

High-Yield Discount Obligations

         The  Senior  Discount  Notes  will  constitute  "applicable  high yield
discount  obligations"  ("AHYDOs")  if the  yield  to  maturity  of such  Senior
Discount  Notes  equals or exceeds  the sum of the  applicable  federal  rate in
effect at the time of the issuance of the Senior Discount Notes (the "AFR") plus
five percentage points. For___________ 1997, 


                                     -130-

<PAGE>

the  long-term  AFR  is % and  the  mid-term  AFR  is %  (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.

                                     -131-

<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.
Holders" above, and to the 


                                     -132-

<PAGE>

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 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.


                                     -133-

<PAGE>

         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 other  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 British Aerospace and Matra Marconi Space Investments

                  Under an agreement  between Orion and British  Aerospace,  $50
million  of  Junior  Subordinated  Debentures  are to be  purchased  by  British
Aerospace  in  the  British  Aerospace   Investment.   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
(payable  even during any event of default on the Notes)  solely in Orion common
stock at a price of $14 per  share.  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  and certain dividends or issuances
of stock to all stockholders.

                  British  Aerospace  has  agreed  that  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
consideration  consisting of the number of shares of Common Stock  issuable upon
conversion of the Junior  Subordinated  Debentures  multiplied by the greater of
(i) the average  closing price of the Common Stock over the preceding 20 trading
days  or (ii)  $17.50  per  share.  Alternatively,  Orion  may  arrange  for the
disposition  of the Common  Stock  received  upon the  conversion  of the Junior
Subordinated Debentures (or the Junior Subordinated Debentures themselves) in an
underwritten public offering,  subject to British Aerospace being guaranteed the
greater of (a) 95% of the  average  closing  price of the Common  Stock over the
preceding 20 trading days or (b) $17.50 per share.  British  Aerospace will have
the right to demand one  underwritten  public  offering  of the shares of Common
Stock received upon conversion of the Junior Subordinated Debentures and include
such shares in other Orion public offerings.

                  The Junior Subordinated Debentures will be subordinated to all
other  indebtedness of the Company,  including the Notes.  The Trustee will have
the right to vote the proxy of the Junior  Subordinated  Debenture  holders with
respect to any plan of reorganization.  The Junior Subordinated  Debentures will
contain  only  limited  covenants  so long as $50  million  or more of the Notes
remain outstanding,  but a more extensive set of covenants will apply after less
than $50  million  of Notes are  outstanding.  From and after the time when less
than $50  million  of Notes  remain  outstanding,  in the  event of a change  of
control  of Orion  (any  stockholder  becoming  the  owner of 51% or more of the
voting rights or designating a majority of the Board of Directors), either Orion
or British Aerospace 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 the same purchase price as in the event of redemption.

                  The  purchase  of  the  Junior   Subordinated   Debentures  is
conditioned upon the following: (i) completion of the Exchange; (ii) termination
of all of  British  Aerospace's  obligations  under the Orion 1 Credit  Facility
Support; (iii) net proceeds to Orion from the Offering of at least $225 million;
(iv) Orion's  payment to British  Aerospace 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,  the  contractor  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  (or an
affiliate) in Junior Subordinated Debentures.

                  The  Debenture  Investments  are 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 Satellite  Control System  Contract 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 349  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 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.


                                     -137-

<PAGE>

                  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,  respectively,  subject to anti-dilution adjustments
in the  case of  recapitalizations  or  issuances  of  Common  Stock  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%

                  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.  Orion has the right to redeem the Senior Preferred


                                     -138-
<PAGE>

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 thirty of the forty-five  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 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  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).

                  Conversion  to Common  Stock.  Holders  of Series C  Preferred
Stock have the right, at any time after the issuance thereof,  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 

                                     -139-

<PAGE>

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.

                  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 the  conversion  price of $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 Closing  Date,  then the
number of shares of Common  Stock into  which the  shares of Series C  Preferred
Stock are  converted  is  increased by the number of shares of Common Stock that
would be payable as dividends  on the Series C Preferred  Stock over six months;
provided, however, that at least one year of dividends is paid.

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 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 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.
Certain  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  of  securities  by  Orion  (a  "piggy-back"
registration).  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 certain  "demand"  rights 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.


                                     -140-

<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").

                  o  Subsequent  Shelf  Registration   Rights.   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
Orion 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 Piggy-back  Registration  statement or
otherwise  incident  to the  performance  of or  compliance  by  Orion  with the
provisions  of  the  Registration  Rights  Agreement  relating  to a  Piggy-back
Registration.

                  Junior  Subordinated  Debentures.  The shares of Common  Stock
issuable upon conversion of the Junior Subordinated Debentures (and up to 86,505
shares  of Common  Stock  held by  British  Aerospace)  will have the  following
registration rights:

                  o Shelf Registration  Rights.  Orion will prepare and, as soon
as  practicable  (but no later than 60 days  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 shares the Common Stock issuable
upon  conversion  of  the  Junior  Subordinated  Debentures  in an  Underwritten
Offering. The Company will not be obligated to effect more than one Underwritten
Offering  in any 12  month  period.  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 that
exceeds $25 million.

                  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 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 the Common Stock  issuable
upon  conversion  of the Junior  Subordinated  Debentures  with respect to which
Orion has received  written requests for inclusion  


                                     -141-
<PAGE>

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 Piggy-back
registration statement or otherwise incident to the performance of or compliance
by Orion with the provisions of the registration  rights agreement relating to a
Piggy-back 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 Code ("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."

                  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 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
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 Exchange,  the Company will
have  approximately  25.9 million shares of Common Stock  outstanding on a fully
diluted basis. Approximately 14.5 million of these shares will initially be held
by the Company'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 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.

                  In general,  under Rule 144 as currently  in effect,  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  259,000 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 the Company at any time during the 90 days preceding a
sale, and who has beneficially owned the shares 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, including British Aerospace (which could
acquire  additional shares upon conversion of the British  Aerospace  Debenture)
will own the remaining 11.4 million shares after the Transactions,  all of which
will be deemed to be  "restricted  securities"  as that term is  defined in Rule
144,  promulgated under the Securities Act.  Moreover,  each Exchanging  Partner
will enter into a Transfer  Restriction  Agreement regarding the transfer of the
shares of Common Stock issuable upon conversion of 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  within the
corporate  group).   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 , or (iv) not involving a public  distribution or offering  registered
under  the  Securities  Act  and  is  not  made  through  a  broker,  dealer  or
market-maker  pursuant to Rule 144 under the  Securities Act (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 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  would  have  on the  market  price  of such
securities  prevailing  from time to time or on the  ability  of the  Company to
raise additional equity financing.  Nevertheless,  the foregoing could adversely
affect prevailing market prices. See "Principal Stockholders."

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

         Under the terms  and  conditions  of the  Underwriting  Agreement,  the
Underwriters  are  committed  to take and pay for all of the  Units,  if any are
taken.

         The  Underwriters  propose  to  offer  the  Units in part  directly  to
purchasers at the initial  public  offering price 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,
Notes and Warrants,  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 Company and the several  Underwriters have agreed to indemnify each
other against certain  liabilities,  including  liabilities under the Securities
Act.

                                    APPRAISAL

                APPRAISAL OF 

Orion Network Systems, Inc.

         ______ has  prepared an appraisal  estimating  the Fair Market Value of
the Orion 1  satellite  to be  $_____  million  as of  September  30,  1996 (the
"Valuation  Date").  ______  defines the Fair Market Value,  as of the 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.

         The appraised  value of the asset as of September 30, 1996 assumes that
Orion 1 will continue to be operational,  and that Orion 1's performance will be
consistent  with the  assumptions  provided by  management.  Because  events and
circumstances  frequently do not occur as expected and for the reasons described
in the Company's  prospectus  relating to the issuance of Units  compromised  of
Senior  Notes Due 2007 and  Warrants and Units  compromised  of Senior  Discount
Notes Due 2007 and Warrants, 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.  Please  refer to
________ Appraisal  Memorandum for Orion 1 (the "______  Memorandum"),  which is
incorporated  herein by reference  and a copy of which may be obtained  from the
Company   at  no   charge,   for  other   material   assumptions,   information,
qualifications  and limitations  upon liability  related to ________  appraisal.
This letter is qualified in its entirety by reference to the ______ Memorandum.

         In addition  to  determining  the Fair Market  Value of Orion 1, ______
calculated  replacement  cost as a measure of Fair  Market  Value.  However,  we
rejected  replacement cost because,  in ________  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.

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:

                                                    December 31, 1995

</TABLE>

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

2. Summary of Significant Account Policies (Continued)

    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 determined at the date such payments are deemed probable of being paid,
generally at the time satellite launch insurance expires and commercial in orbit
insurance  becomes  effective  ($14.8 million  relating to Orion 1). 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   $8,589,062,   $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 $3,535,052, $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

2. Summary of Significant Account Policies (Continued)

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.

    Following  is a summary of the  components  of the net deferred tax asset at
December 31, 1995 and 1994 (in thousands):

    Tax benefit of temporary differences:

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

3. Orion Atlantic

    Orion  Atlantic  is  a  Delaware  limited   partnership  formed  to  provide
international private communications networks and basic transponder capacity and
capacity  services  (including  ancillary  ground  services) to  businesses  and
institutions  with  trans-Atlantic  and  intra-European  needs. The business was
organized by OrionSat,  the general  partner of Orion  Atlantic.  The  principal
purposes of Orion Atlantic are to finance the construction, launch and operation
of up to two  telecommunications  satellites  in  geosynchronous  orbit over the
Atlantic Ocean and to establish a multinational sales and service  organization.
OrionSat was granted  final  authority by the FCC on June 27, 1991 to construct,
launch and operate an international  communications  satellite system, including
two orbital slots at 37.5(degree) W.L. and 47(degree) 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.

    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  satisfactory.  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,  effective
July 1, 1995,  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.

3. Orion Atlantic (Continued)

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

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

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

3. Orion Atlantic (Continued)

    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.

4. Commitments and Contingencies (Continued)

    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.

    Future minimum lease payments are as follows:

                           1996       $   774,357
                           1997           793,716

    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.

           the nine months ended September 1995 and 1996 is unaudited)


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.  Also included in satellite
incentive  obligations  are $4.1 million  relating to accruals  prior to July 1,
1995 and $1.1  million of interest  accretion  during the period July 1, 1995 to
December 31, 1995.

    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 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  ("SSL")  pursuant to a stock  purchase  agreement  (the
"Agreement").

6. Redeemable Preferred Stock and Stockholders' Equity (Continued)

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

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

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

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

    Stock options outstanding at December 31:

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

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

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

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

    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.

6. Redeemable Preferred Stock and Stockholders' Equity (Continued)

    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.

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

7. Investment in Asia Pacific

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

8. Fair Values of Financial Instruments

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

9. Condensed Financial Information of Orion

    As described in Notes 3 and 5, the net assets,  credit  facilities and other
resources of Orion Atlantic are restricted to the  construction and operation of
the satellite  system.  Presented  below are condensed  balance  sheets of Orion
(parent  company  only  basis)  at  December  31,  1995 and  1994 and  condensed
statements of operations  and cash flows for the years ended  December 31, 1995,
1994 and 1993. All material  contingencies,  obligations and guarantees of Orion
have  been  separately  disclosed  in  the  preceding  notes  to  the  financial
statements.

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 Orion 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
Space and Communications,  Ltd ("APSC") 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.

11.  Subsequent events (unaudited) (Continued)

    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 $  representing  Units  consisting  of Senior  Notes,  due 2007 and
warrants to purchase  common  stock,  and an aggregate of $  representing  units
consisting  of $ 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  Junior  Subordinated  Convertible
Debentures, respectively. Such debentures are expected to bear interest at 8.75%
payable  semiannually  in Orion  common  stock  (valued at $14 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 Investment;  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 the OAP Minority Interest Acquisition.

    In November  1996,  Orion entered into a contract with DACOM Corp., 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 May
1999).  Prior to  launch,  payments  will be held in escrow  and are  subject to
refund if the leased  transponders  are not launched and in service by May 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  Orion  would be entitled  to retain all  deposited  funds.  Prior to
launch,  payments will be held in escrow and are subject to refund if the leased
transponders  are not  launched  and in service by May 1999.  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 (6) month period
beginning  six (6) months after the  commencement  date, as defined in the Joint
Investment  Agreement,  and ending one (1) year after commencement date and will
terminate  at  that  time or at any  time  the  Joint  Investment  Agreement  is
terminated.

    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.

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

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

                                      II-3
<PAGE>

duty of  loyalty  to the  corporation  or its  shareholders,  (ii)  for  acts or
omissions  not in good  faith or  involving  intentional  misconduct  or knowing
violation of law,  (iii) under  Section 174 of the Delaware Code for approval of
an unlawful  dividend or an unlawful  stock  purchase or redemption and (iv) for
any transaction  from which the director derived an improper  personal  benefit.
This  provision  also does not affect a  director's  responsibilities  under any
other  laws,   such  as  the  federal   securities  laws  or  state  or  federal
environmental laws.

     OrionNet's  Bylaws  provide  that,  except as expressly  prohibited by law,
OrionNet  shall  indemnify any person who was or is a party (or threatened to be
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,  officer,  employee
or agent of OrionNet (or is or was serving any other  enterprise  at the request
of OrionNet),  against expenses,  liabilities and losses  (including  attorney's
fees),  judgments,  fines and amounts paid or to be paid in settlement  actually
and reasonably  incurred by such person in connection with such action,  suit or
proceeding.

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

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

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

     International Private Satellite Partners,  L.P. ("IPSP"). The Third Amended
and Restated Agreement of Limited Partnership of International Private Satellite
Partners,  L.P.  (the "IPSP  Partnership  Agreement")  provides that neither the
general  partner  (OrionSat)  nor  any of its  affiliates  ,  nor  any of  their
respective partners, officers,  directors,  employees or agents, shall be liable
to IPSP or its limited partners for any losses

                                      II-4
<PAGE>

sustained or liabilities incurred as a result of any act or omission, so long as
such conduct does not constitute bad faith,  fraud,  gross  negligence,  willful
misconduct or breach of any fiduciary duty.

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

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

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


ITEM 15.  Recent Sales of Unregistered Securities.

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

Common Stock

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

                                      II-5
<PAGE>


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.

  Preferred Stock

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

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

                                      II-6
<PAGE>

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.

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 in the Financial Statements or Notes thereto.

ITEM 17. Undertakings.

                  The undersigned Registrants hereby undertake that:

                  (1) 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

                  (2) 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
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.
