                          ORBCOMM GLOBAL CAPITAL CORP
 THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME ON           ,
                             1996, UNLESS EXTENDED.
                            ------------------------
 
     ORBCOMM Global, L.P., a Delaware limited partnership (the "Company"), and
its wholly owned subsidiary ORBCOMM Global Capital Corp. (the "Co-Obligor"), as
joint and several obligors, are offering on the terms and subject to the
conditions set forth in this Prospectus and the accompanying Letter of
Transmittal (the "Letter of Transmittal" which together with the Prospectus
constitute the "Exchange Offer"), to exchange $1,000 principal amount of
registered 14% Series B Senior Notes due 2004 with Revenue Participation
Interest (the "Exchange Notes"), for an equal principal amount of 14% Senior
Notes due 2004 with Revenue Participation Interest (the "Old Notes") of which an
aggregate of $170 million principal amount is outstanding as of the date hereof.
The Company and the Co-Obligor are herein collectively referred to as the
"Issuers." The form and terms of the Exchange Notes will be substantially
identical to the form and terms of the Old Notes except that the Exchange Notes
are registered under the Securities Act of 1933, as amended (the "Securities
Act") and, will not bear legends restricting the transfer thereof. The Exchange
Notes will evidence the same debt as the Old Notes and will be entitled to the
benefits of an Indenture dated as of August 7, 1996, governing the Old Notes and
the Exchange Notes (the "Indenture"). The Indenture provides for the issuance of
both the Exchange Notes and the Old Notes. The Exchange Notes and the Old Notes
are sometimes referred to herein collectively as the "Senior Notes." The holders
of the Senior Notes are sometimes referred to herein collectively as the
"Holders." The Exchange Offer is being made to satisfy certain contractual
obligations of the Issuers.
 
     SEE "RISK FACTORS" ON PAGE 16 OF THIS PROSPECTUS FOR A DISCUSSION OF
CERTAIN FACTORS WHICH HOLDERS OF OLD NOTES SHOULD CONSIDER IN CONNECTION WITH
THE EXCHANGE OFFER.
                            ------------------------
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
       PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
        REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
- --------------------------------------------------------------------------------
 
 THE COMPANY WILL ACCEPT FOR EXCHANGE ANY AND ALL VALIDLY TENDERED OLD NOTES ON
 OR PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON             , 1996 (IF AND AS
 EXTENDED, THE "EXPIRATION DATE"). TENDERS OF OLD NOTES MAY BE WITHDRAWN AT ANY
 TIME PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE EXPIRATION DATE. THE
 EXCHANGE OFFER IS NOT CONDITIONED UPON ANY MINIMUM PRINCIPAL AMOUNT OF OLD
 NOTES BEING TENDERED FOR EXCHANGE. OLD NOTES MAY BE TENDERED ONLY IN INTEGRAL
 MULTIPLES OF $1,000. IN THE EVENT THE COMPANY TERMINATES THE EXCHANGE OFFER
 AND DOES NOT ACCEPT FOR EXCHANGE ANY OLD NOTES, THE COMPANY WILL PROMPTLY
 RETURN ALL PREVIOUSLY TENDERED OLD NOTES TO THE HOLDERS THEREOF.
- --------------------------------------------------------------------------------
                            ------------------------
 
                THE DATE OF THIS PROSPECTUS IS           , 1996.
<PAGE>   5
 
     The Exchange Notes will mature on August 15, 2004 and will bear fixed
interest at the rate of 14% per annum from their date of issuance. Interest on
the Exchange Notes will be payable semi-annually in arrears on February 15 and
August 15 of each year, commencing February 15, 1997. Revenue Participation
Interest (as defined herein) is payable on the Senior Notes, on each such
interest payment date, in an aggregate amount equal to 5.0% of System Revenue
(as defined herein) for the six-month period ending on December 31 or June 30
most recently completed prior to such interest payment date. Holders of Exchange
Notes will receive interest on February 15, 1997 from the date of initial
issuance of the Exchange Notes, plus an amount equal to the accrued interest on
the Old Notes from the date of original issuance of the Old Notes to the date of
exchange thereof for the Exchange Notes. Such interest will be paid with the
first interest payment on the Exchange Notes. Interest on the Old Notes accepted
for exchange will cease to accrue upon issuance of the Exchange Notes.
 
     The Issuers will not be required to make any mandatory redemption or
sinking fund payments with respect to the Senior Notes. The Senior Notes will be
redeemable at the option of the Issuers, in whole or in part, at any time on or
after August 15, 2001 at the redemption prices set forth herein plus accrued and
unpaid interest, if any, to the date of redemption. In the event of a Change of
Control (as defined herein), the Issuers will be required to make an offer to
repurchase the Senior Notes, at a price equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Liquidated Damages (if any)
thereon to the date of purchase. See "Description of Senior Notes -- Certain
Covenants -- Repurchase at the Option of Holders -- Change of Control."
 
     The Senior Notes are senior obligations of the Issuers and rank pari passu
in right of payment with all existing and future senior Indebtedness (as defined
herein) of the Issuers and will rank senior in right of payment to any future
subordinated Indebtedness of the Issuers; provided, however, that certain
Indebtedness of the Issuers and their subsidiaries may be secured by assets held
by the Issuers or their subsidiaries subject to certain restrictions described
herein. See "Description of Senior Notes -- Certain Covenants -- Liens." As of
June 30, 1996, after giving effect to the Old Notes Offering, the aggregate
amount of outstanding liabilities (including trade payables) of the Issuers, on
a consolidated basis, would have been approximately $186 million. The Senior
Notes will be fully and unconditionally guaranteed (limited only to the extent
necessary to avoid such Guarantees being considered a fraudulent conveyance
under applicable law) on a joint and several basis (the "Guarantees") by ORBCOMM
USA, L.P., ORBCOMM International Partners, L.P., Orbital Communications
Corporation and Teleglobe Mobile Partners (the "Guarantors"). The Guarantees of
each of the Guarantors will rank pari passu in right of payment with all senior
Indebtedness of the Guarantors and senior in right of payment to all
Indebtedness expressly subordinated to the guarantee of such Guarantor. The
guarantees are non-recourse to the shareholders and/or partners of such
Guarantors (including Orbital Sciences Corporation, Teleglobe Inc. and
Technology Resources Industries Bhd.) and no shareholder or partner of such
Guarantors will have any liability for any claim under the Senior Notes.
 
     Each broker-dealer that receives Exchange Notes for its own account in
exchange for Old Notes, where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of
Exchange Notes received in exchange for Old Notes where such Old Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. The Old Notes are designated for trading in the Private
Offerings, Resales and Trading through Automated Linkages ("PORTAL") market. To
the extent Old Notes are tendered and accepted in the Exchange Offer, the
principal amount of outstanding Old Notes will decrease with a resulting
decrease in the liquidity of the market therefor. Following consummation of the
Exchange Offer, holders of Old Notes who were eligible to participate in the
Exchange Offer but who did not tender their Old Notes will not be entitled to
certain rights under the Registration Rights Agreement (as defined herein), and
such Old Notes will continue to be subject to certain restrictions on transfer.
Accordingly, the liquidity in the market for the Old Notes could be adversely
affected. No assurance can be given as to the liquidity of the trading market
for either the Old Notes or the Exchange Notes.

Global, L.P., ORBCOMM USA, L.P. ("ORBCOMM USA") and ORBCOMM International
Partners, L.P. ("ORBCOMM International"). Certain capitalized terms used in this
Prospectus are defined in the Glossary. All references in this Prospectus to "$"
or "dollars" are to U.S. dollars. Holders of the Senior Notes should carefully
consider the specific matters set forth under "Risk Factors" beginning on page
16 as well as the other information and data included in this Prospectus.
 
                                  THE COMPANY
 
   
     The Company is establishing the first commercial low-Earth orbit ("LEO")
satellite-based mobile data and messaging communications system that will be
available on a global basis (the "ORBCOMM System"). The ORBCOMM System, planned
to be fully deployed in early 1998, is designed to provide reliable, low-cost,
two-way global data and messaging communications through a constellation of 28
LEO satellites and a complement of associated ground infrastructure situated
around the world. The Company believes that there is significant global demand
for its low-cost data and messaging communications services. Major target
markets include worldwide mobile asset tracking; remote industrial monitoring
and control applications; environmental data collection; and real time
person-to-person and machine-to-machine communications, including two-way
Internet electronic mail ("email") communications and recreational and business
messaging. The Company anticipates that the ORBCOMM System will be used: (i) as
a complement to existing or proposed tower-based services such as paging and
other narrowband personal communications services ("PCS"), providing geographic
coverage in areas these systems are unable to reach; and (ii) to enhance data
applications currently being provided through the public switched telephone
network ("PSTN") and the public switched data network ("PSDN"). In addition, the
Company expects that the introduction of its low-cost, reliable data and
messaging communications will lead to the development of new applications and
services.
    
 
     The Company currently offers commercial intermittent data communications
services in the United States through its existing network, which consists of
two LEO satellites launched in April 1995 and related U.S. ground
infrastructure. When fully deployed, the ORBCOMM System is designed to provide
data and short, alphanumeric paging-like messaging communications coverage
virtually anywhere on the Earth's surface in a reliable and cost-effective
manner. In contrast to "Big LEO" systems, which are designed primarily for voice
applications and require satellite communications systems that are estimated to
cost in excess of $2 billion to construct and deploy, the ORBCOMM System, which
is a "Little LEO" system, is focused on data communications and messaging
applications and will be constructed and deployed for approximately $258 million
(with additional amounts needed to fund initial operation of the ORBCOMM System
and certain debt service obligations). The ORBCOMM System is designed to address
the substantial existing and growing demand for communications services
worldwide, without the high cost and geographic and technical limitations
imposed by other communications systems.
 
     In October 1994, a subsidiary of Orbital Sciences Corporation ("Orbital")
became the first company to be awarded Federal Communications Commission ("FCC")
authority to construct, launch and operate a LEO satellite-based data and
messaging communications system in the United States. Today, the ORBCOMM System
is the only commercial Little LEO system that is fully licensed for all segments
of its system in the United States. Certain portions of the radio spectrum were
allocated by the International Telecommunications Union ("ITU") for use by
Little LEO systems, such as the ORBCOMM System, on an international basis in
1992. The Company intends to enter into agreements with International Licensees,
who will pursue the requisite local regulatory approvals for each foreign
country in which the ORBCOMM System will operate and who will pay fees for
access to the ORBCOMM System in their territory.
 
     In 1995, in addition to the successful launch of the first two ORBCOMM
System satellites, the Company: (i) completed initial development and
construction of the ground infrastructure located in the
 
                                        1
<PAGE>   8
 
United States and associated network control systems; and (ii) tested prototype
Subscriber Communicators. The two ORBCOMM System satellites and four U.S. Earth
stations currently are providing data communications services, focused on
monitoring applications, to the U.S. environmental and oil and gas industries,
with tracking and positioning applications targeted for the near future. As of
June 30, 1996, the ORBCOMM System had transmitted in excess of one million
messages and successfully completed extensive internal and third-party testing,
including a rigorous demonstration program conducted by the U.S. Department of
Defense ("DoD") as part of its Joint Warrior Interoperability Demonstration '95.
 
     To use the ORBCOMM System, a user creates a text message utilizing a
computer or Subscriber Communicator device, which message is sent to the nearest
ORBCOMM System satellite and delivered to an ORBCOMM Earth station, which
supports communication with the satellites, and then to the Gateway Switching
System, which processes the messages. Within the Gateway, the message is
processed using a combination of ORBCOMM-developed and commercial email
software, and sent on to its ultimate destination. If desired, an
acknowledgement message is returned to the sender. The final delivery may be to
another Subscriber Communicator or may make use of public/private X.25 data
networks, the Internet, or text-to-fax conversion.
 
   
     The Company intends to distribute its services globally in a cost-effective
manner through the use of Resellers in the United States and International
Licensees around the world. The Company is in the process of negotiating and
signing agreements with Resellers, each of whom will be responsible for
marketing to end customers in a specific industry and/or market and generally is
expected to develop software applications to facilitate use of ORBCOMM System
services by such industry or market segment. To date, 25 reseller agreements
have been signed with companies including Arinc, Inc., Boatracs, Inc., Corexco
Consulting Services, Inc., Globitrac, Inc., IWL Communications, Inc., QUALCOMM,
Incorporated and the Stevens Water Monitoring Division of Leupold & Stevens,
Inc. The Company has signed ten Memoranda of Understanding with potential
International Licensees and is in active negotiations with nine other potential
International Licensees; taken together, these 19 potential International
Licensees represent approximately 35 countries around the world. The Company
intends to convert substantially all its existing Memoranda of Understanding
into Service License Agreements during the next three to 18 months. In addition,
the Company has signed Service License Agreements with three International
Licensees. On October 15, 1996, ORBCOMM signed a Service License Agreement with
European Company for Mobile Communicator Services, B.V., ORBCOMM Europe
("ORBCOMM Europe"), a consortium of European companies, which was given the
exclusive right to market services using the ORBCOMM System to approximately 40
European countries. ORBCOMM has also executed a Service License Agreement with
ORBCOMM Canada Inc. ("ORBCOMM Canada"), which is controlled by Teleglobe Inc.
("Teleglobe"), and which has been given the exclusive right to market services
in Canada using the ORBCOMM System. The third Service License Agreement was
signed with Cellular Communications Network (Malaysia) Sdn. Bhd. ("Celcom"), a
wholly owned subsidiary of Technology Resources Industries Bhd. ("TRI"), and
grants Celcom the exclusive right to market ORBCOMM System services in Malaysia,
Singapore and Brunei.
    
 
   
     ORBCOMM is a limited partnership formed in 1993 to develop, construct,
operate and market the ORBCOMM System. The general and limited partnership
interests in ORBCOMM are held by each of Orbital Communications Corporation
("OCC"), a subsidiary of Orbital, and Teleglobe Mobile Partners ("Teleglobe
Mobile"), a Delaware general partnership whose interests are wholly owned on an
indirect basis by Teleglobe and TRI, a Malaysian holding company that controls
the largest cellular operator in Malaysia. OCC and Teleglobe Mobile have
invested approximately $160 million in the ORBCOMM project. The Company believes
that such equity contributions, together with the proceeds of the Old Notes
Offering (as defined below) and cash expected to be generated from operations,
will be sufficient to fund the ORBCOMM System, including: (i) all capital
expenditures necessary to deploy the ORBCOMM System; and (ii) all required
working capital until at least the first quarter of 1998, when full deployment
of the ORBCOMM System is planned to have occurred. There can be no assurance,
however, that additional capital will not be necessary.

BUSINESS STRATEGY
 
The principal elements of the Company's business strategy include:
 
   
     Real Time, Reliable Worldwide Coverage.  The fully deployed ORBCOMM System
has been designed to provide for the delivery and receipt of data communications
and short, alphanumeric paging-like messages anywhere in the world on a highly
efficient and cost-effective basis. The ORBCOMM System's worldwide coverage will
enable it to provide tracking, monitoring and messaging services, including
Internet email capability, to customers that are currently beyond the geographic
reach of existing terrestrial wireline or wireless systems. The ORBCOMM System
is designed to deliver reliable communications services through the use of
acknowledgment and store-and-forward capabilities. ORBCOMM expects that, with a
planned constellation of 28 satellites, the ORBCOMM System will provide
communications availability generally exceeding 95% of each 24-hour period in
the United States and other temperate zones in the Northern and Southern
Hemispheres and averaging 75% of each 24-hour period in the equatorial region.
On full deployment, the ORBCOMM System is designed to transmit a U.S.-initiated
message ranging in length from six bytes to 100 bytes, depending on system
loading, in from approximately three to 25 seconds.
    
 
     First-to-Market.  The ORBCOMM System began providing commercial
intermittent service in February 1996. Prior to commencing commercial
operations, the space segment, network and management control systems, U.S.
Gateway and prototype Subscriber Communicators were tested extensively to ensure
technical viability. The Company believes that the existence of an in-service,
commercially operational system provides substantial "first-to-market" benefits,
including: (i) reducing technical risk; (ii) increasing the attractiveness of
the ORBCOMM System to potential Resellers, International Licensees and
Subscriber Communicator manufacturers; (iii) facilitating and encouraging the
development of software by Resellers and other application developers for a
variety of market applications because of the ability to test the hardware and
software in an actual operating environment; and (iv) developing a customer base
before other competing Little LEO systems are fully deployed, which the Company
believes will not occur before 2000. There can be no assurance, however, that
there will be no delays in the existing schedule associated with the
construction or deployment of the ORBCOMM System.
 
     Global Distribution of Services.  The Company believes the ORBCOMM System
can rapidly achieve a global presence in a cost-effective manner by capitalizing
on the significant resources of Resellers and International Licensees worldwide.
The Company plans to provide services in the United States through Resellers,
many of whom have an existing, well-established market presence through their
existing customer bases, market-specific brand name recognition and distribution
networks. Outside the United States, the Company will enter into Service License
Agreements with International Licensees who will be responsible in their
territory for, among other things, procuring and installing the necessary
Gateways, obtaining all regulatory approvals to provide services using the
ORBCOMM System and operating and marketing services using the ORBCOMM System.
The Company intends to select its International Licensees primarily by
evaluating the ability of the International Licensee to distribute and market
successfully the Company's services. Key components of such an evaluation
include the prospective International Licensee's: (i) reputation in the
marketplace; (ii) existing distribution capabilities and infrastructure; (iii)
financial condition and other resources; and (iv) ability to obtain the
requisite local regulatory approvals.
 
   
     Low-Cost Subscriber Communicators.  The Company is committed to promoting
the production of lightweight Subscriber Communicators that have a long battery
life and are widely available at prices attractive to a broad customer base. The
Company has provided extensive design specifications and technical and
engineering support to its various Subscriber Communicator manufacturers. The
Company currently has a development agreement with Kyushu Matsushita Electric
Company, Ltd. (also known as "Panasonic"). The Company is in the process of
finalizing manufacturing and sales support agreements with Panasonic and has
executed Subscriber Communicator Manufacturing Agreements, which include terms
regarding the development, manufacture and sales support for Subscriber
Communicators, with Scientific-Atlanta, Inc. ("Scientific-Atlanta"), Magellan
Corporation ("Magellan"), Torrey Science Corporation ("Torrey Science") and
Stellar Electronics Ltd. ("Stellar"), an Israeli company that is a subsidiary of
Tadiran Ltd., a leading Israeli electronics company. Panasonic has received
authorization from the Company to manufacture
    
 
                                        3
<PAGE>   10
 
   
two basic Subscriber Communicators, one with and one without the ability to
receive positioning signals from the Global Positioning Satellite ("GPS")
system, both of which are now commercially available. Torrey Science received
authorization from the Company in August 1996 to manufacture a basic Subscriber
Communicator and in September 1996, Stellar received authorization from the
Company to manufacture a basic subscriber communicator specifically designed for
mobile, outdoor, industrial and/or power sensitive applications. The Company
expects that both Torrey Science and Stellar will have units commercially
available in the first quarter of 1997. The Company believes that once its other
Subscriber Communicator manufacturers have units that are commercially available
and once the overall production volume for Subscriber Communicators increases,
the price for Subscriber Communicators will decline substantially. Panasonic and
Stellar have informed the Company that, in lots of at least several thousand,
the price for their respective Subscriber Communicators will be approximately
$550 per unit.
    
 
     Expertise of Strategic Partners.   Orbital and Teleglobe, the Company's
partners, have invested approximately $160 million in the ORBCOMM project. The
Company has used and will continue to use its partners' expertise and
capabilities to enhance the ORBCOMM System, including expertise in the design,
construction and deployment of satellites and the operation of international
wireline and wireless telecommunication services.
 
     Orbital, a Delaware corporation headquartered in Dulles, Virginia and with
offices in five countries, is the founder of the ORBCOMM project, and through
its subsidiary, OCC, has a 50% Participation Percentage interest in ORBCOMM.
Orbital is a space technology and satellite services company, with annual
revenues in 1995 of approximately $364 million, that designs, manufactures,
operates and markets a broad range of space products and services, including
launch systems, satellites, space sensors and electronics, ground systems and
software products, satellite access products and communications and information
services. Under the terms of the Procurement Agreement between Orbital and
ORBCOMM, Orbital will, among other things, construct 34 satellites (including
eight ground spares), launch 26 satellites and, on an optional basis, launch the
eight ground spares. The satellites and launch services are provided on a
fixed-priced basis, although the Procurement Agreement contains certain
performance incentives with respect to the satellites.
 
   
     Teleglobe, a Canadian corporation with 1995 revenues of approximately C$1.6
billion, provides international telecommunications services to over 240
countries worldwide through a network of submarine cables and satellite Earth
stations. Teleglobe currently has offices in ten countries. Teleglobe is owned
approximately 22% by BCE Inc., which is the largest public corporate entity in
Canada, and indirectly approximately 20% by Telesystem Ltd., which also has an
interest in Telesystem International Wireless Corporation N.V. ("TIW"). TIW has
paging and cellular interests in several countries around the world, including
China, Mexico and India. Teleglobe has substantial experience as an
intercontinental provider of telecommunication services and has played and
continues to play an important advisory role in the ORBCOMM project generally
and in the Company's marketing and distribution strategy in particular.
    
 
     Teleglobe has formed a partnership, Teleglobe Mobile, with TRI to hold its
interest in the ORBCOMM project. TRI operates the largest and one of the
fastest-growing cellular networks in Malaysia, with over 800,000 subscribers.
TRI also has cellular and paging joint ventures in five countries.
 
     The Company's principal executive offices are located at 21700 Atlantic
Boulevard, Dulles, Virginia 20166, and the Company's telephone number is (703)
406-6000. The Company's Web site is located at http://www.orbcomm.net.
 
SIGNIFICANT MILESTONES
 
  MILESTONES ACHIEVED TO DATE
 
     Through June 30, 1996, the Company has achieved the following milestones:
 
     - FCC Authorization.  In October 1994, OCC was granted authority by the FCC
       to construct, launch and operate 36 LEO satellites in the United States
       (the "FCC License"). In May and June 1995, OCC received FCC authority to
       operate its four U.S. Earth stations and to provide services in the
       United States to Subscriber Communicators.
 
                                        4
<PAGE>   11
 
     - Deployment of First Two Satellites.  In April 1995, the first two of the
       28 satellites expected to comprise the ORBCOMM System were deployed.
       These two satellites are operational.
 
     - Equity Commitments.  In September 1995, the partners increased their
       committed equity in the ORBCOMM project to a total of approximately $160
       million.
 
     - Gateways.  As of December 1995, the U.S. Gateway, including three of the
       four Earth stations and key portions of the ORBCOMM System's control
       segments, was operational. In May 1996, the fourth Earth station became
       operational.
 
     - Commercial Service.  In February 1996, after extensive testing, the
       ORBCOMM System commenced commercial service.
 
   
     - Subscriber Communicators.  The Company has reached agreements with
       several manufacturers for the development and manufacture of various
       types of Subscriber Communicators. Subscriber Communicators became
       commercially available from Panasonic in March 1996, in August 1996 a
       Torrey Science Subscriber Communicator passed type acceptance testing and
       in September 1996, a Stellar Subscriber Communicator passed type
       acceptance testing.
    
 
   
     - Resellers.  The Company has signed agreements with 25 Resellers in the
       United States who will provide services for, among others, the trucking,
       marine, oil and gas and environmental industries.
    
 
   
     - International Licensees.  The Company has signed Memoranda of
       Understanding with ten potential International Licensees and is in active
       discussions with nine additional potential International Licensees; taken
       together, these 19 potential International Licensees represent
       approximately 35 countries around the world. On October 15, 1996, the
       Company signed a Service License Agreement with ORBCOMM Europe that
       authorizes ORBCOMM Europe on an exclusive basis to offer services using
       the ORBCOMM System in approximately 40 European countries. The Company
       has also signed a Service License Agreement with ORBCOMM Canada and a
       Service License Agreement with Celcom.
    
 
  FUTURE MILESTONES
 
     The Company expects to achieve the following future milestones:
 
   
     - Deployment of Additional Satellites.  By the first quarter of 1998, the
       Company plans to have launched an additional 26 satellites, for a total
       constellation of 28 satellites. The Company has an option to launch an
       additional eight ground spare satellites that, if launched as a fourth
       plane, would complete deployment of the 36 LEO satellites authorized by
       the FCC License.
    
 
     - Subscriber Communicators.  By the first quarter of 1997, the Company
       expects that Subscriber Communicators will be commercially available from
       Torrey Science and Stellar.
 
   
     - Resellers.  The Company is currently in negotiations with 14 additional
       potential Resellers who will provide services for, among others, the
       utility, rail carrier and law enforcement industries.
    
 
   
     - International Licensees.  By December 1997, the Company plans to have
       converted substantially all its ten existing Memoranda of Understanding
       into definitive Service License Agreements with International Licensees.
    
 
     - Commencement of Global, Real Time Service.  In 1998, following the launch
       and deployment of an additional 26 satellites and extensive review of the
       fully deployed ORBCOMM System, the Company plans to be able to offer real
       time communications services.
 
CONSTELLATION DESIGN AND IMPLEMENTATION STRATEGIES
 
     The ORBCOMM System has been designed to provide for the delivery and
receipt of short messages anywhere in the world on a highly efficient and
cost-effective basis. The Company believes that multiple aspects of the ORBCOMM
System design will result in a low-cost product offering worldwide and that the
 
                                        5
<PAGE>   12
 
implementation plan for the ORBCOMM System should reduce the risk of cost
overruns, system performance shortfalls and system deployment delays. Important
components of the ORBCOMM System design and implementation strategies include:
(i) the design, development and deployment of a low-cost satellite system; (ii)
the development of a communications protocol specifically designed for data and
messaging communications; (iii) the use of contractual and other means to
mitigate the risk of delays and system failures; and (iv) the use of
advantageous radio frequencies. See "Business -- Constellation Design and
Implementation Strategies."
 
RECENT DEVELOPMENTS
 
     On August 7, 1996, the Issuers and Guarantors engaged in an offering (the
"Old Notes Offering") of the Old Notes pursuant to exemptions from registration
under the Securities Act.
 
     The net proceeds from the sale of the Old Notes Offering were approximately
$164 million (after deducting discounts and commissions to the initial
purchasers thereof and expenses of the Old Notes Offering). The Company will
apply all the net proceeds of the Old Notes Offering to: (i) the design,
construction, launch, operation and marketing of the ORBCOMM System through the
date of full deployment of the ORBCOMM System, including the procurement of
satellites, launch services, launch insurance and U.S. ground segment
components; (ii) related development, operating and marketing expenses; (iii)
the purchase of the Pledged Securities; and (iv) the deposit into a segregated
account an amount sufficient to pay when due all remaining interest and
principal payments on the Company's Loan and Security Agreement with MetLife
Capital Corporation ("MetLife") (the "MetLife Note"). Pending such uses, the net
proceeds will be invested in short-term, investment-grade securities.
 
   
     The table on the following page summarizes the estimated sources and uses
of capital by ORBCOMM for the period from June 30, 1993 (date of inception)
through the first quarter of 1998, when full deployment of the ORBCOMM System is
planned to have occurred.

     ORBCOMM believes that the net proceeds of the Old Notes Offering and the
capital contributions of the ORBCOMM partners, together with expected cash from
operations, will be sufficient to fund the Company's operations through at least
the first quarter of 1998, when full deployment of the ORBCOMM System is planned
to have occurred. Additional funds may be necessary in the event of delay, cost
overruns or any shortfall in estimated levels of operating cash flow, or to meet
unanticipated expenses. There can be no assurance that ORBCOMM will be able to
obtain any such additional financing on favorable terms or on a timely basis.

                               THE EXCHANGE OFFER
 
     The Exchange Offer applies to $170 million aggregate principal amount of
the Old Notes. The form and terms of the Exchange Notes are substantially the
same as the form and terms of the Old Notes except that the Exchange Notes will
be registered under the Securities Act and, therefore, will not bear legends
restricting the transfer thereof. The Exchange Notes will evidence the same debt
as the Old Notes and both series of Senior Notes will be entitled to the
benefits of the Indenture and treated as a single class of debt securities
thereunder. See "Description of Senior Notes."
 
THE EXCHANGE OFFER............   The Issuers are offering to exchange $170
                                   million principal amount of Exchange Notes
                                   for a like principal amount of Old Notes.
                                   Exchange Notes may be exchanged only in
                                   multiples of $1,000 principal amount. The
                                   Issuers will issue the Exchange Notes on or
                                   promptly after the Expiration Date. The terms
                                   of the Exchange Notes and Old Notes are
                                   substantially identical. See "The Exchange
                                   Offer."
 
                                 Based on an interpretation by the staff of the
                                   Commission set forth in no-action letters
                                   issued to third parties, the Issuers believe
                                   that, with the exceptions discussed herein,
                                   Exchange Notes issued pursuant to the
                                   Exchange Offer in exchange for Old Notes may
                                   be offered for resale, resold and otherwise
                                   transferred by any holder thereof (other than
                                   (i) a broker-dealer who purchases such
                                   Exchange Notes directly from the Issuers to
                                   resell pursuant to Rule 144A or any other
                                   available exemption under the Securities Act
                                   or (ii) a person that is an "affiliate" of
                                   the Issuers within the meaning of Rule 405
                                   under the Securities Act) without compliance
                                   with the registration and prospectus delivery
                                   provisions of the Securities Act, provided
                                   that (i) the Holder is acquiring the Exchange
                                   Notes in the ordinary course of its business
                                   and (ii) that such Holder is not
                                   participating, and has no arrangement or
                                   understanding with any person to participate,
                                   in the distribution of such Exchange Notes.
                                   However, the Issuers have not sought, and do
                                   not intend to seek, their own no-action
                                   letter, and there can be no assurance that
                                   the Commission's staff would make a similar
                                   determination with respect to the Exchange
                                   Offer. Each broker-dealer that receives
                                   Exchange Notes for its own account in
                                   exchange for Old Notes must acknowledge that
                                   it will deliver a prospectus in connection
                                   with any resale of such Exchange Notes. See
                                   "Plan of Distribution."

                                   October   , 1996 as the record date for the
                                   Exchange Offer (the "Record Date") for the

                                   unless extended, in which case the term
                                   "Expiration Date" shall mean the latest date
                                   and time to which the Exchange Offer is so
                                   extended.

                                   customary conditions, which may be waived by

                                   commercial bank, trust company or other

                                   to tender on its behalf. If such beneficial

                                   Act or an exemption from registration
                                   thereunder and in compliance with applicable
                                   state securities laws. In the event the
                                   Issuers complete the Exchange Offer, the
                                   interest rate on Old Notes will remain as
                                   stated thereon and Holders of Old Notes will
                                   have no further rights under the Registration
                                   Rights Agreement (as defined herein).
 
   
CERTAIN TAX CONSIDERATIONS....   Latham & Watkins, counsel to the Company, has
                                   advised the Company that because the Exchange
                                   Notes should not be considered to differ
                                   materially from the Old Notes, the exchange
                                   of Exchange Notes for Old Notes should not
                                   result in any material federal income tax
                                   consequences to Holders exchanging Old Notes
                                   for Exchange Notes. For a full description of
                                   the basis of, and limitations on, this
                                   opinion, see "Certain Federal Income Tax
                                   Considerations."

RANKING.......................   The Exchange Notes will be senior obligations
                                   of the Issuers and will rank pari passu in
                                   right of payment with all existing and future
                                   senior Indebtedness of the Issuers and will
                                   rank senior in right of payment to any future
                                   subordinated Indebtedness of the Issuers;
                                   provided, however, that certain Indebtedness
                                   incurred by the Issuers and their
                                   subsidiaries in the future may be secured by
                                   assets held by the Issuers or their
                                   subsidiaries subject to certain restrictions
                                   described herein. As of June 30, 1996, after
                                   giving effect to the Old Notes Offering, the
                                   aggregate amount of outstanding liabilities
                                   (including trade payables) of the Issuers, on
                                   a consolidated basis, would have been
                                   approximately $186 million. The Indenture
                                   permits the Issuers to incur additional
                                   Indebtedness, including senior Indebtedness,
                                   subject to certain limitations.
 
GUARANTEES....................   The Exchange Notes will be fully and
                                   unconditionally guaranteed on a joint and
                                   several basis by the Guarantors, limited only
                                   to the extent necessary for each such
                                   Guarantee to not constitute a fraudulent
                                   conveyance under applicable law. The
                                   Guarantee of each Guarantor will rank pari
                                   passu in right of payment with all senior
                                   Indebtedness of the Guarantors and senior in
                                   right of payment to all Indebtedness
                                   expressly subordinated to the guarantee of
                                   such Guarantor. The guarantees are
                                   non-recourse to the shareholders and/or
                                   partners of such Guarantors (including
                                   Orbital, Teleglobe and TRI) and no
                                   shareholder or partner of such Guarantors
                                   will have any liability for any claim under
                                   the Notes. See "Description of Senior
                                   Notes -- Guarantees."
 
OPTIONAL REDEMPTION...........   The Exchange Notes may be redeemed at the
                                   option of the Issuers, in whole or in part,
                                   at any time on or after August 15, 2001, at a

                                   herein), the Issuers will be required to make

                                   a price equal to 101% of the aggregate
                                   principal amount thereof, plus accrued and
                                   unpaid interest, if any, to the date of

                                   "Indenture") contains certain covenants that

                                   Guarantors and their Restricted Subsidiaries

                               THE ORBCOMM SYSTEM
 
                             SUMMARY SATELLITE DATA
 
     The ORBCOMM System is a global satellite communications system comprising a
constellation of LEO satellites, certain terrestrial facilities including
Gateways, network control systems and Subscriber Communicators that is intended
to provide two-way data and messaging communications services throughout the
world. The most significant characteristics of the satellites that comprise the
ORBCOMM System, such as their design specifications, coverage and design life,
as well as licensing and launch information for the satellites, are summarized
in the following table.

(1) Each of the satellites that comprise the ORBCOMM System is an Orbital
    MicroStar(TM) satellite, weighing approximately 95 pounds and measuring
    approximately 41 inches in diameter, 6.5 inches in height, 170 inches in
    deployed length and 88 inches in "deployed width at solar arrays." Each of
    the ORBCOMM System satellites is currently authorized to operate in the
    137.0-138.0 MHz band with a power flux density ("PFD") limit of -125 dB
    (W/m(2)/4 kHz) for (satellite-to-subscriber and -Earth station)
    transmissions. Also, each satellite currently is authorized to operate at
    400.1 MHz ( 25 kHz) for satellite-to-subscriber transmissions with no PFD
    limit. Each of the ORBCOMM System satellites also is currently authorized to
    operate in the 148.0-149.9 MHz band for uplink (subscriber- and Earth
    station-to-satellite) transmissions at five watts. OCC has requested that
    the FCC allocate additional frequency located at 137.0-138.0 MHz and
    149.9-150.05 MHz for use by Little LEO systems. See
    "Business -- Regulation -- Second Processing Round."
(2) The two ORBCOMM System satellites that are currently in orbit provide
    communications availability in the United States for approximately 10% of
    each 24-hour period (eight to ten passes over a fixed point on the Earth's
    surface each day), with maximum outages of approximately nine hours. ORBCOMM
    expects that, with a planned constellation of 28 satellites, the ORBCOMM
    System will provide communications availability generally exceeding 95% of
    each 24-hour period in the United States and other temperate zones in the
    Northern and Southern hemispheres and averaging 75% of each 24-hour period
    in the equatorial region.
(3) The license for the ORBCOMM System issued to OCC by the FCC on October 20,
    1994 supersedes the earlier experimental licenses granted to OCC and
    includes the two satellites launched by OCC in April 1995. The October 20,
    1994 license grants OCC the authority to construct, launch and operate 36
    LEO satellites in the United States.
(4) Each of the future launch dates identified represents the currently targeted
    launch date.
(5) These two satellites are intended to be launched as a secondary payload on a
    Taurus launch vehicle, also manufactured by Orbital.
(6) These eight satellites represent ground spares that may be deployed as a
    fourth plane by the Company, provided that, subject to FCC approval, the
    Company may determine not to so deploy such satellites.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Exchange Notes offered hereby.
 
DEVELOPMENT STAGE COMPANY
 
     Expectation of Continued Losses and Accumulated Deficits.  ORBCOMM is a
development stage company that commenced commercial service in the United States
with its first two satellites on February 1, 1996 and, therefore, has generated
only nominal revenues from its limited operations to date. ORBCOMM's activities
have focused primarily on acquisition of U.S. regulatory approvals for operation
of the ORBCOMM System, design, construction and deployment of its initial
satellites and associated network systems, negotiation of reseller agreements,
identification of potential International Licensees in countries outside the
United States, identification of Subscriber Communicator manufacturers and
hiring of management and other key personnel.
 
     The continued development of ORBCOMM's business and deployment of the
ORBCOMM System will require significant capital expenditures, a substantial
portion of which will need to be incurred prior to the realization of
significant revenues from the ORBCOMM System. Together with ORBCOMM's operating
expenses, these capital expenditures will result in a negative cash flow until
an adequate revenue-generating customer base is established. ORBCOMM has
incurred cumulative deficiency of income over expenses of approximately $8.9
million through June 30, 1996 and it expects such losses to continue for the
foreseeable future. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." The Company does not expect that the
ORBCOMM System will generate positive cash flow until the ORBCOMM System is
fully deployed and operational, which is expected to occur in 1998. There can be
no assurance that the Company will achieve its objectives by the targeted dates.
See "Business."
 
     Limited Operating and Financial Data.  Prospective investors have limited
operating and financial data about the ORBCOMM System on which to base an
evaluation of the ORBCOMM System's performance and an investment in the Senior
Notes. ORBCOMM's ability to provide commercial service on a worldwide basis and
to generate positive operating cash flow will depend on its ability to, among
other things: (i) successfully construct and deploy the remaining satellites in
the ORBCOMM System in a timely manner; (ii) develop Reseller capabilities within
the United States and license arrangements outside the United States sufficient
to capture and retain an adequate customer base; and (iii) through its existing
or proposed International Licensees, obtain the necessary foreign regulatory
authority and construct the necessary ground infrastructure outside the United
States. Given ORBCOMM's limited operating history, there can be no assurance
that it will be able to overcome these barriers, to develop a sufficiently large
revenue-generating customer base to service its indebtedness or to compete
successfully in the communications industry.
 
   
     Potential Additional Capital Requirements.  The Company currently expects
to require approximately $354 million for capital expenditures, development and
operating costs of the ORBCOMM System and the purchase of the Pledged Securities
from June 30, 1993 (date of inception) through at least the first quarter of
1998, when full deployment of the ORBCOMM System is expected to have occurred.
Through June 1996, the Company had expended approximately $136 million for the
design, construction, deployment and/or procurement of satellites, launch
vehicles, portions of the network control elements and the U.S. ground segment
and for market development and regulatory activities. To finance such
expenditures, the Company has obtained approximately $160 million in equity
contributions from its partners and received net proceeds of approximately $164
million from the Old Notes Offering and approximately $5 million from proceeds
of the Company's senior secured debt. The Company believes that the net proceeds
of the Old Notes Offering and the capital contributions of the ORBCOMM partners,
together with expected cash from operations, will be sufficient to fund the
Company's operations through at least the first quarter of 1998, when full
deployment of the ORBCOMM System is planned to have occurred. There can be no
assurance that the Company will generate sufficient cash from operations, or
that expenses will not exceed the Company's estimates, such that additional
capital will not be required. In particular, additional capital would be
required in the event that: (i) there are delays in the deployment of the
ORBCOMM System as a result of launch or satellite failure or
    
 
                                       16
<PAGE>   23
 
otherwise; (ii) the Company incurs additional costs in completing the ORBCOMM
System including as a result of modifying the design of all or a portion of the
ORBCOMM System in the event of any technical difficulties or regulatory
requirements; (iii) there is an increase in the Company's estimated net
operating deficit indirectly as a result of the Company's incurring significant
unanticipated expenses; or (iv) reseller and international licensee agreements
for additional markets or territories are not entered into at the times or on
the terms anticipated by ORBCOMM. See "Business -- Development Milestones."
There can be no assurance that additional capital will be available for any of
the foregoing purposes from the public or private markets or from ORBCOMM's
existing partners on favorable terms or on a timely basis, if at all. A
substantial shortfall in funding would delay or prevent completion of the
ORBCOMM System. In view of the Company's current stage of development, the risk
of any of the aforementioned occurrences is substantial. The Company's ability
to achieve positive cash flow will depend on successful and timely design,
construction and deployment of the ORBCOMM System, the successful marketing of
its services by Resellers and International Licensees, and the ability of the
ORBCOMM System to compete successfully against its competitors, as to which
there can be no assurance.
 
SUBSTANTIAL LEVERAGE; RESTRICTIVE COVENANTS
 
     As of June 30, 1996, on a pro forma basis after giving effect to the Old
Notes Offering and the contribution of the partners' remaining capital
commitments, the Company's total indebtedness would have been $174 million and
its partners' capital accounts would have totaled $148 million. On a pro forma
basis after giving effect to the Old Notes Offering, the Company's deficiency of
earnings before fixed charges to cover fixed charges for the six months ended
June 30, 1996 and the year ended December 31, 1995 would have been $21.4 million
and $25.0 million, respectively.
 
     The Indenture contains, and any additional financing agreements may
contain, certain restrictive covenants. The restrictions contained in the
Indenture affect, and in some cases significantly limit or prohibit, among other
things, the ability of the Company to incur indebtedness, make prepayments of
certain indebtedness, pay dividends, make investments, engage in transactions
with affiliates, issue capital stock, create liens, sell assets and engage in
mergers and consolidations. If the Company fails to comply with the restrictive
covenants in the Indenture, the Company's obligation to repay such obligations
may be accelerated.
 
     The successful implementation of the Company's strategy, among other
things, is necessary for the Company to be able to meet its debt service. The
Company currently has no significant sources of revenue. In addition, the
Company's ability to satisfy its obligations once the ORBCOMM System is
operational will depend on the Company's future performance, which is subject to
a number of factors, many of which are beyond the Company's control. There can
be no assurance that the Company can complete the ORBCOMM System or that, once
completed, the Company will generate sufficient cash flow from operating
activities to meet its debt service and working capital requirements. Any
failure or delay in deployment of the ORBCOMM System could have a material
adverse effect on the Company's business, results of operations and financial
condition, including failure to meet these debt service requirements.
 
     The Company's high degree of leverage could have important consequences to
the Holders of the Senior Notes, including that: (i) a substantial portion of
the Company's net cash provided by operations will be committed to the payment
of the Company's interest expense and principal repayment obligations and will
not be available to the Company for its operations, capital expenditures,
acquisitions or other purposes; (ii) the Company's ability to obtain additional
financing in the future for working capital, capital expenditures or
acquisitions may be limited; (iii) the Company will be highly leveraged, which
may place it at a competitive disadvantage and limit the Company's flexibility
in reacting to changes in its business; and (iv) the Company's borrowings under
any Bank Credit Facility may be at variable rates of interest, which would
result in higher interest expense in the event of an increase in interest rates.
See "Description of Senior Notes."
 
LAUNCH RISKS
 
   
     For the ORBCOMM System to be fully deployed and offer real time data and
messaging services under the Company's current schedule, ORBCOMM plans to launch
26 satellites by the first quarter of 1998. The
    
 
                                       17
<PAGE>   24
 
   
Company has contracted with Orbital to provide three separate Pegasus XL launch
vehicles to deploy the satellites eight at a time, and one Taurus launch vehicle
to deploy two satellites. Satellite launches are subject to significant risks,
including failure of the launch vehicle, which may result in disabling damage to
or loss of the satellites, or failure of the satellites to achieve their proper
orbit. There can be no assurance that any of the proposed ORBCOMM System
satellite launches will be successful. Through August 21, 1996, Orbital has
conducted a total of eight standard Pegasus missions, all of which were fully or
partially successful. Whether a mission is fully or partially successful depends
on the particular mission requirements designated by the customer. In the two
partially successful standard Pegasus missions, the satellites achieved useful
orbits and were able to be operated by the customer and performed at least part
of their intended missions. Prior to its successful flights in March, July, and
August 1996, the modified Pegasus XL, an enhanced version of the standard
Pegasus, had two unsuccessful flights, one occurring in June 1994 and the other
in June 1995. The first Pegasus XL failure was caused by inaccurate aerodynamic
modeling of the vehicle. The second Pegasus XL failure resulted from human
assembly error involving the improper installation of a small component that
prevented the Stage 1/Stage 2 interstage from properly separating from Stage 2.
Following a comprehensive review of design, assembly, test and operations
procedures, the Pegasus XL returned to flight on March 8, 1996, successfully
launching a satellite for the U.S. Air Force to its intended orbit, and had
successful flights on July 2, 1996 and August 21, in each case delivering a
National Aeronautics and Space Administration ("NASA") satellite to its
designated orbit. There are four additional Pegasus XL launches currently
planned before the scheduled deployment of the remaining ORBCOMM satellites
using this launch vehicle. The failure of any one of these launch vehicles could
result in a delay in the deployment of the ORBCOMM System satellites. For the
ORBCOMM System to function at maximum design efficiency, each individual plane
of satellites comprising the constellation must be deployed into its proper
orbit.
    
 
     Orbital's Pegasus XL vehicle is launched from beneath a modified Lockheed
L-1011 aircraft. In 1992, Orbital entered into a ten-year lease for the Lockheed
L-1011. In the event the L-1011 is unavailable for any reason, the Company would
experience significant timing delays as a result of Orbital having to acquire
and modify a new launch vehicle or the Company having to arrange for deployment
of the satellites using an alternative launch vehicle or by means of a ground
launch. There can be no assurance that another aircraft could be obtained and
properly modified or that alternate launch services could be obtained on a
timely or cost-effective basis, if at all.
 
     ORBCOMM intends to launch two additional satellites in 1997 as a secondary
payload on a Taurus launch vehicle, also manufactured by Orbital. The Taurus
launch vehicle, the design and technology of which is derived largely from the
Pegasus launch vehicle, had a successful first launch in 1994. Because these two
satellites will be launched as a secondary payload, they are subject to the
scheduling restrictions imposed by the availability of the primary payload.
Accordingly, it may not be possible to launch the two satellites at the time
currently planned, if at all.
 
TECHNOLOGICAL RISKS
 
     Integration and Operation Risks.  The ORBCOMM System is exposed to the
risks inherent in a large-scale complex communications system employing advanced
technology. The operation of the ORBCOMM System will require the detailed design
and integration of communications technologies and devices ranging from
satellites operating in space and Subscriber Communicators to Gateways located
around the globe. There can be no assurance that, even if built to
specifications, the ORBCOMM System will function as expected in a timely and
cost-effective manner. The failure of any of the diverse and dispersed elements
to function and coordinate as required could delay the full deployment of the
ORBCOMM System or render it unable to perform at the quality and capacity levels
required for success.
 
     The ORBCOMM satellites have limited redundancy against technical failure
and there can be no assurance of a particular satellite's longevity. A number of
factors will affect the useful lives of the ORBCOMM System satellites, including
quality of construction, expected gradual environmental degradation of solar
panels and durability of component parts. Random failure of satellite components
could result in damage to or loss of a satellite. In rare cases, satellites
could also be damaged or destroyed by electrostatic
 
                                       18
<PAGE>   25
 
storms or collisions with other objects. ORBCOMM's operating results would be
adversely affected in the event the useful life of the satellites were
significantly shorter than five years.
 
     The Company has experienced and continues to experience, from time to time,
certain technical difficulties with its initial two satellites, including
outages of certain electronic systems and subsystems resulting in the temporary
inability to process subscriber communications. While the Company believes these
technical difficulties have been addressed as experienced, and that none of the
difficulties has resulted or will result in a significant degradation of
satellite performance, there can be no assurance that performance degradation in
these two satellites will not occur in the future.
 
     In addition, the Company is modifying the existing satellite design to
enhance overall satellite performance. For example, the Company is redesigning
the satellite antenna to increase satellite availability to subscribers and to
increase satellite capacity. While such design modifications will be subject to
extensive design reviews and testing prior to deployment of the satellites,
there can be no assurance that the modifications will be successful or that the
modified satellites will operate as intended.
 
   
     Development of Subscriber Communicators.  The successful operation of the
ORBCOMM System depends on the design, construction and commercial availability
of Subscriber Communicators designed to support the specific needs of users. See
"Business -- The ORBCOMM System -- System Architecture -- Subscriber Segment."
To ensure availability of Subscriber Communicators having different functional
capabilities in sufficient quantities to meet demand, the Company has entered
into a development agreement with Panasonic and is in the process of finalizing
manufacturing and sales support agreements with Panasonic. The Company also has
executed Subscriber Communicator Manufacturing Agreements with Scientific-
Atlanta, Magellan, Torrey Science and Stellar. Panasonic has received
authorization from the Company to manufacture two basic Subscriber
Communicators, one with and one without GPS functionality, both of which are now
commercially available. Torrey Science received authorization from the Company
in August 1996 and Stellar received authorization from the Company in September
1996 to manufacture a basic Subscriber Communicator. The Company expects that
both Torrey Science and Stellar will have units commercially available in the
first quarter of 1997. Realization of the full market potential for the
Company's communications services depends upon the availability of Subscriber
Communicators at prices attractive to customers. There can be no assurance that
the Company's Subscriber Communicator manufacturers will successfully design and
manufacture Subscriber Communicators to the Company's specifications or in
sufficient quantities to satisfy the expected needs of the ORBCOMM System, or
that the price of such Subscriber Communicators will decline so as to make them
affordable to the broad customer base intended by the Company.
    
 
SCHEDULE DELAYS
 
   
     Delay in the timely construction, deployment and implementation of full
commercial operation of the ORBCOMM System could result from a variety of
causes, including delays encountered in the construction, integration and
testing of the ORBCOMM System, a delayed or unsuccessful launch, delays caused
by design reviews in the event of a launch vehicle failure or a loss of
satellites, or as the result of a delay in the FCC's approval of OCC's request
for modification of its FCC license filed in October 1995 (the "Modification
Request") or other events beyond the control of ORBCOMM. The construction
schedule for the satellites in the ORBCOMM System requires a rate for satellite
production and testing that is unprecedented for commercial communications
systems. The schedule set forth under the Procurement Agreement has been delayed
as a result of, among other things, enhancements made to the design of the
satellites and delays in certain subcontractor deliveries. Such delays have
reduced the contingency period within the overall schedule for the development
and deployment of the ORBCOMM System. A significant delay in the deployment of
satellites from the Company's current schedule could materially and adversely
affect the Company's operations. In addition, a significant delay in the
manufacture of Subscriber Communicators could have a material adverse effect on
the Company's results of operations. The success of the ORBCOMM System depends
on Subscriber Communicators being available to potential subscribers on a timely
basis to take advantage of the intermittent data communications services
currently available and the real time data and
    
 
                                       19
<PAGE>   26
 
messaging services that will be available on full deployment of the ORBCOMM
System. There can be no assurance that the satellites or the Subscriber
Communicators will be available on a timely basis.
 
REGULATORY RISKS
 
     Licensing Risks; Domestic.  ORBCOMM's business may be affected by the
regulatory activities of various U.S. government agencies, primarily the FCC. On
October 20, 1994, the FCC granted to OCC the FCC License, authorizing OCC to
construct, launch and operate the ORBCOMM System for the purpose of providing
two-way data and message communications and position determination services in
the United States. Although the FCC License is currently valid, it is subject to
revocation if OCC fails to satisfy certain conditions or to meet certain
prescribed milestones, including the December 2000 milestone by which OCC must
launch 36 satellites, although OCC may determine, subject to FCC approval, to
launch fewer than 36 satellites by such date. While the FCC License is valid for
a period of ten years from the operational date of the first ORBCOMM satellite,
OCC is required, three years prior to expiration of the FCC License, to apply
for a license renewal with the FCC. Although the FCC has indicated that it is
generally inclined to grant renewal applications of existing Little LEO
licensees, there can be no assurance that the FCC will in fact renew the FCC
License. Should the FCC revoke the FCC License or fail to renew the FCC License
on application by OCC, or if OCC fails to satisfy any of the conditions of the
FCC License, such action would have a material adverse impact on ORBCOMM's
business. Finally, the business of ORBCOMM could be adversely affected by the
adoption of new laws, policies or regulations, or changes in the interpretation
or application of existing laws, policies and regulations, that modify the
present regulatory environment. See "Regulation."
 
   
     ORBCOMM's authorization to provide services is subject to the Modification
Request. This request seeks to modify the frequency plan to permit the ORBCOMM
System to use fewer, higher data rate subscriber downlink channels, which
should, among other things, enable it to avoid interfering with other existing
and proposed systems. The Modification Request has been opposed by numerous
other Little LEO systems. OCC recently reached an agreement with Starsys Global
Positioning, Inc. ("Starsys") and the National Oceanic and Atmospheric
Administration ("NOAA") with respect to technical matters raised by the
Modification Request. While OCC expects that the FCC will grant the Modification
Request in the near future, should the Modification Request be denied or
significantly delayed by the FCC, it could have a material adverse effect on
ORBCOMM's business in the event the number and usage patterns of subscribers
mandates increased capacity. The Company believes that the failure of the FCC to
grant the Modification Request would not, however, affect the constellation
deployment schedule or materially adversely affect the Company's planned
revenues through December 31, 1997 because such revenues are generally planned
to be derived from license fees from International Licensees and Gateway sales.
    
 
     As a private carrier, OCC currently is not subject to the restrictions that
apply to common carriers or to providers of Commercial Mobile Radio Services
("CMRS"). There can be no assurance, however, that in the future, OCC will not
engage in business of a type such that the FCC would deem it a common carrier or
a CMRS provider or that the FCC will not in the future exercise its
discretionary authority to apply the CMRS or common carrier rules to MSS
providers. See "Regulation." The application of these rules could have an
adverse effect on OCC's business by, for instance, requiring OCC to offer all
customers just, reasonable and non-discriminatory rates, by subjecting OCC to
certain tariff filing requirements, by subjecting OCC to state regulation (if
OCC were deemed to be a common carrier) and by subjecting OCC to various alien
ownership and control restrictions applicable to common carriers and CMRS
providers.
 
     LICENSING RISKS; INTERNATIONAL.  ORBCOMM's business is affected by the
regulatory authorities of the countries in which it or its International
Licensees will operate. Obtaining local regulatory approval for operation of the
ORBCOMM System will be the responsibility of the International Licensee in each
territory. While International Licensees will be selected, in part, based on
their perceived qualifications to obtain the requisite local approvals, there
can be no assurance that they will be successful in doing so, and if they are
not successful, service will not be available in such territories. Although many
countries have moved to privatize the provision of communications service and to
permit competition in the provision of such services, some countries continue to
require that all communications service be provided by a government-owned
entity. The
 
                                       20
<PAGE>   27
 
Company anticipates that most of its International Licensees will be private
entities. Therefore, in those countries that require services to be provided by
a government-owned entity, the Company may be unable to offer services using the
ORBCOMM System. ORBCOMM's inability to offer service in a foreign country or
countries could have a material adverse effect on ORBCOMM's business. Regulatory
provisions in countries in which the Company or its International Licensees seek
to operate may impose impediments on the Company's or the International
Licensees' operations and there can be no assurance that such restrictions would
not be unduly burdensome. ORBCOMM's business may also be adversely affected by
regulatory changes resulting from judicial decisions and/or adoption of
treaties, legislation or regulation by the national authorities where the
ORBCOMM System plans to operate.
 
   
     The United States, on behalf of OCC, is required to coordinate the
frequencies used by the ORBCOMM System through the ITU. ITU frequency
coordination is a necessary prerequisite to obtaining interference protection
from other satellite systems. There is no penalty for launching a satellite
system prior to completion of the ITU coordination process, although protection
from interference through this process is only afforded as of the date of
successful completion of the process and notification of the system by ITU.
Although the United States has substantially completed the ITU coordination
process with respect to the ORBCOMM System, it is still required to coordinate
the ORBCOMM System with Russia and France. Although the Company believes that
approval of the Modification Request would facilitate its coordination efforts
with Russia and could facilitate its coordination efforts with France, failure
of the FCC to approve the Modification Request would not preclude successful
coordination with Russia or France. There can be no assurance that the FCC will
grant the Modification Request. There also can be no assurance that, even if the
Modification Request is granted, OCC will be successful in coordinating the
ORBCOMM System with the Russian and French systems. Any delay in or failure to
successfully complete the ITU coordination process may result in potential
interference to the ORBCOMM System by other mobile satellite systems operating
internationally, which could have a material adverse effect on ORBCOMM's
business.
    
 
LIMITED INSURANCE
 
     The Company expects to obtain launch insurance for each scheduled Pegasus
XL launch that would provide it with the necessary funds to procure a
replacement launch vehicle in the event of a launch vehicle failure. The Company
also expects to procure in-orbit satellite insurance against the failure of
satellites after placement of satellites into commercial service. The foregoing
insurance would not cover the cost to construct replacement satellites in the
event of a launch failure, or the cost to construct and launch satellites in the
event of the loss of satellites after a successful launch but prior to the time
satellites are placed into commercial service. Pursuant to the terms of the
Procurement Agreement, the Company is purchasing eight additional satellites to
be used as ground spares. Such ground spares represent self-insurance against
the risk of a loss of satellites. Until such time as the Company is required to
use its ground spare satellites, ORBCOMM does not intend to obtain insurance to
cover the cost of obtaining replacement satellites in the event of a launch
vehicle failure or an in-orbit failure prior to placement of such satellites
into commercial service. In the event that the Company is required to use its
ground spare satellites, ORBCOMM will be obligated under the terms of the
Indenture to procure insurance for subsequent missions covering a loss of
satellites as a result of a launch vehicle failure or an in-orbit failure prior
to placement of such satellites into commercial service. The Company does not
have in-orbit insurance for the two satellites currently operational and does
not intend to procure launch or in-orbit insurance for the two satellites
currently planned to be launched as a secondary payload on a Taurus launch
vehicle.
 
     Based on current market conditions, the Company expects that premiums for
launch insurance would be less than ten percent for Pegasus XL launches and that
in-orbit satellite insurance after placement of the satellites into commercial
service would be approximately 1.5% to 2% per year. An adverse change in
insurance market conditions or other factors outside the Company's control at
the time the Company seeks to procure such insurance may, however, cause
premiums to be significantly higher than current estimates. The Company believes
that its procurement of the spare satellites will offset in part the risk of a
launch failure. There can be no assurance, however, that launch or satellite
failures will not occur and that launch or in-orbit
 
                                       21
<PAGE>   28
 
satellite insurance will be available to the Company in the future or, if
available, at a cost or on terms acceptable to the Company.
 
LIMITED LIFE OF SATELLITES
 
     The ORBCOMM System satellites, which constitute a substantial portion of
the Company's total assets, will have a limited useful life. The additional
first-generation satellites are designed to operate for five years. ORBCOMM
anticipates using funds generated from operations to develop a second generation
of satellites. If sufficient funds from operations are not available and ORBCOMM
is unable to obtain financing for the second-generation constellation, ORBCOMM
will not be able to deploy a second-generation satellite constellation to
replace first-generation satellites at the end of their useful lives. There can
be no assurance that additional capital will be available to develop the second
generation of satellites on favorable terms or on a timely basis, if at all.
 
MARKET ACCEPTANCE
 
     The success of the ORBCOMM System and the Company's ability to pay interest
and principal on the Senior Notes will depend on subscriber acceptance of
ORBCOMM System services. Subscriber acceptance of ORBCOMM System services will
depend on a number of factors, including the technical capabilities of the
ORBCOMM System, the cost of Subscriber Communicators, the price of ORBCOMM
System services and the extent, availability and price of alternative
communications services. There can be no assurance that price, service
limitations or Subscriber Communicator size, weight or cost will not result in
more significant limitations on customer acceptance than the Company
anticipates. The ORBCOMM System will provide a new data transfer and messaging
capacity to certain markets where the Company has identified a demand for such
types of communications services. The Company expects that introduction of the
ORBCOMM System will lead to the development of new applications and services
that will use the capacity provided by the ORBCOMM System. As with any new
service, however, there can be no assurance that development of such
applications will occur.
 
     Realization of the full market potential for the Company's services will
depend on the availability of Subscriber Communicators that are reasonably
priced and that have certain features attractive to the market. One of the
Company's Subscriber Communicator manufacturers, Panasonic, currently has
Subscriber Communicators that are commercially available. The Company expects
that once its other Subscriber Communicator manufacturers have units that are
commercially available and once the overall production volume for Subscriber
Communicators begins to increase, the price for Subscriber Communicators will
decline substantially. Panasonic and Stellar have informed the Company that, in
lots of at least several thousand, the price for their respective Subscriber
Communicators will be approximately $550 per unit. There can be no assurance,
however, that the price of such Subscriber Communicators will decline so as to
make them affordable to a broad customer base. Also, many Subscriber
Communicators are currently being designed to offer particular features the
Company believes will be attractive to potential end-users, such as GPS. There
can be no assurance, however, that the market will demand the types of features
currently offered by or proposed to be offered by these Subscriber
Communicators, that the Company's Subscriber Communicator manufacturers will
continue to manufacture Subscriber Communicators or that technological or other
design developments over the years will not render these Subscriber
Communicators obsolete.
 
     The success of the ORBCOMM System depends in part on the ability of the
Company to offer its data and messaging communications services at rates
attractive to the market. Although the Company believes that its pricing
structure will make the ORBCOMM System an affordable and thus attractive option
for the provision of such services to the industries and markets it has
targeted, the cost to end-users for ORBCOMM System services is largely beyond
the control of the Company.
 
RELIANCE ON RESELLERS AND INTERNATIONAL LICENSEES
 
     In the United States, ORBCOMM intends to rely on Resellers to market and
distribute its services to retail customers. The willingness of companies to
become Resellers will depend on a variety of factors,
 
                                       22
<PAGE>   29
 
including regulatory restrictions, whether potential Resellers perceive the
ORBCOMM System services to be compatible with their own and whether the proposed
compensation provides an adequate return. ORBCOMM's reseller agreements provide
that the Resellers will use all reasonable commercial efforts to market and
distribute ORBCOMM System services, but in most cases do not require the
Resellers to meet established sales objectives. There can be no assurance that
ORBCOMM's Resellers will successfully develop a retail market and distribute
ORBCOMM System services.
 
     Outside the United States, the Company will enter into Service License
Agreements with International Licensees who will be responsible in their
territory for, among other things, procuring and installing the necessary
Gateways, obtaining all regulatory approvals to provide services using the
ORBCOMM System, and operating and marketing services using the ORBCOMM System.
The Company intends to select its International Licensees primarily by
evaluating the ability of the International Licensee to distribute and market
successfully the Company's services. Key components of such an evaluation
include the prospective International Licensee's: (i) reputation in the
marketplace; (ii) existing distribution capabilities and infrastructure; (iii)
financial condition and other resources; and (iv) ability to obtain the
requisite local regulatory approvals to operate the ORBCOMM System. There can be
no assurance that the Company's International Licensees will be successful in
obtaining the requisite foreign regulatory approvals or, even if successful,
that they will successfully develop a retail market and distribute ORBCOMM
System services.
 
   
     Although the foregoing factors will be considered by the Company in
evaluating potential International Licensees, there can be no assurance that
each International Licensee will satisfy any one or more of the foregoing
factors. For example, certain of such Resellers and International Licensees are
or are likely to be start-up ventures with limited financial resources, and
there can be no assurance that any such entities will be successful in their
efforts to market effectively the ORBCOMM System or, in the case of
International Licensees, to procure and install the necessary Gateways and
obtain the necessary foreign regulatory authority to operate their systems.
Neither the Company's form of Memorandum of Understanding nor its form of
Service License Agreement obligates or gives the Company the option to construct
the necessary Gateway in the event an International Licensee is unable to do so
on its own. In the future and if an International Licensee is unable to do so,
the Company may decide to construct, or to finance the construction of, the
necessary Gateway. Should the Company make such a decision, there can be no
assurance that the International Licensee or the relevant governmental authority
will permit the construction of such Gateway or that such Gateway will actually
be successfully constructed. There can also be no assurance that the Company
would be able to bear the cost of construction of such Gateway or that the
Company would be able to secure financing for such construction. Although the
costs of constructing a Gateway is uncertain and dependent on a number of
factors, the Company believes that the cost for a Gateway would likely be at
least $3,500,000.
    
 
COMPETITION
 
     Competition in the communications industry is intense, fueled by rapid and
continuous technological advances and alliances between industry participants
seeking to use such advances on an international scale to capture significant
market share. Although no present participant is currently providing the same
global commercial communications services to be provided by the Company, it is
anticipated that the ORBCOMM System will face competition from numerous existing
and potential alternative communications products and services provided by
various large and small companies, including sophisticated two-way
satellite-based data and voice communication services. The Company expects that
potential competitors will include other Little LEO satellite systems and may
include Big LEO and GEO satellite systems and, in some cases, terrestrial
messaging and data systems. If any of the Company's competitors succeed in
marketing and deploying systems with services similar to those expected to be
offered through the ORBCOMM System substantially earlier than the scheduled full
deployment of the ORBCOMM System, the Company's ability to compete in markets
served by such competitors may be adversely affected.
 
     Some of the Company's potential competitors have financial, personnel and
other resources substantially greater than those of the Company. Many of these
competitors are raising capital and may compete with the Company. In addition, a
continuing trend toward consolidation and strategic alliances in the
communications industry could give rise to significant new competitors, and any
foreign competitor may benefit from subsidies
 
                                       23
<PAGE>   30
 
from, or other protective measures by, its home country. There can be no
assurance that some of these competitors will not provide more efficient or less
expensive services.
 
     Satellite-based communications systems are characterized by high up-front
costs and relatively low marginal costs of providing service. A number of Big
LEO and GEO systems are presently being proposed, and, while the proponents of
these systems foresee substantial demand for the services they will provide, the
actual level of demand will not become known until such systems are constructed,
launched and begin operations. Big LEO and GEO systems are designed primarily to
provide two-way voice services that require larger, more complex satellites and
require a circuit-oriented connection over their network to transmit even short
messages, which significantly increases their per-message cost. If, however, the
operators of these systems seek to offer services similar to those offered by
the ORBCOMM System, price competition could be intense.
 
     Two other Little LEO systems currently are licensed by the FCC to provide
data and messaging communications services. One system currently expects to
deploy a two-satellite system to transmit health, research and scientific data
on a delayed basis between developing countries and the United States. The
second system expects to construct and operate a multiple-satellite
constellation that could compete with the ORBCOMM System. This system, which is
now owned 80% by GE American Communications Corporation, could have
significantly greater resources than the Company. There are currently eight
applicants (including OCC) before the FCC in a second processing round for
Little LEO systems, the filing period for which closed on November 16, 1994.
Should the FCC approve any one of the competing second round applications, such
licensee could compete with the Company.
 
     Terrestrial wireless services have certain key advantages over
satellite-based systems, particularly in urban or densely populated areas, in
terms of signal strength and the ability to penetrate various environments (such
as buildings). By contrast, the ORBCOMM System is unable to penetrate buildings
and has limited application in densely populated areas currently serviced by
terrestrial wireless systems. The ORBCOMM System is not intended to compete with
existing and planned terrestrial data and messaging systems. It is expected,
however, that as terrestrial communications services expand to regions currently
underserved or not served by wireline or wireless systems, demand for ORBCOMM
System services in these regions may be reduced. ORBCOMM may also face
competition in the future from companies using new technologies and new
satellite systems. A number of these new technologies, even if they are not
ultimately successful, could have an adverse effect on ORBCOMM as a result of
their marketing efforts. ORBCOMM's business would be adversely affected if
competitors begin operations or existing or new communication service providers
penetrate ORBCOMM's target markets.
 
RELIANCE ON SINGLE SUPPLIER; POTENTIAL CONFLICT OF INTEREST
 
   
     The Company does not independently have, and does not intend to acquire,
except by contracting with other parties, the ability to design, develop,
construct or launch the satellites in the ORBCOMM System. ORBCOMM has contracted
with Orbital to provide these services under the Procurement Agreement. ORBCOMM
may terminate the Procurement Agreement on the failure of Orbital to achieve
certain milestones within 56 weeks after the contracted completion date or on
Orbital's noncompliance with material terms of the Agreement. In the event that
Orbital fails to perform its obligations under the Procurement Agreement, the
deployment of the ORBCOMM System may be delayed until ORBCOMM is able to locate
an alternative provider of necessary services to replace Orbital. In addition, a
material adverse impact on Orbital and its business may adversely affect
Orbital's ability to perform under the Procurement Agreement. The Company has
not identified any alternate provider of the services currently being provided
by Orbital, and there can be no assurance that such an alternative service
provider would be available or, if available, would be available at a cost or on
terms favorable to the Company.
    
 
     Orbital, through OCC, has a substantial interest in the Company.
Accordingly, a conflict of interest may exist between the Company and Orbital
under the Procurement Agreement and other related agreements between Orbital and
OCC. Pursuant to the ORBCOMM Partnership Agreement, significant amendments to
the Procurement Agreement, or other transactions between the Company and
Orbital, are subject to the
 
                                       24
<PAGE>   31
 
approval of Teleglobe Mobile. There can be no assurance, however, that the
potential conflict of interest between the Company and Orbital would not have a
material adverse effect on the Company.
 
   
DEPENDENCE ON INTELLECTUAL PROPERTY RIGHTS
    
 
   
     The Company's success and ability to compete are dependent to a certain
degree on its proprietary technology. The Company relies primarily on copyright
and trade secret law to protect its technology. The Company holds no patents.
The Company's policy is to enter into confidentiality agreements with its
employees, consultants and vendors, which, where appropriate, also contain an
agreement to assign proprietary technology developed during performance
thereunder, and generally to control access to and distribution of its software,
documentation and other proprietary information. Notwithstanding these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the Company's software or other proprietary information without
authorization or to develop similar software independently. In addition, the
laws of countries outside the United States may afford the Company little or no
effective protection of its intellectual property.
    
 
   
     There can be no assurance that the steps taken by the Company will prevent
misappropriation of its technology or that agreements entered into for that
purpose will be enforceable. In addition, litigation may be necessary in the
future to enforce the Company's intellectual property rights, to protect the
Company's trade secrets, to determine the validity and scope of the proprietary
rights of others or to defend against claims of infringement or invalidity. Such
litigation, whether successful or unsuccessful, could result in substantial
costs and diversions of resources, either of which could have a material adverse
effect on the Company's business, financial condition and operating results.
    
 
MARKET ESTIMATES
 
     The Company's description of potential markets for its mobile data and
messaging communications service offerings and estimates of the Company's
addressable markets that are discussed in this Prospectus under the caption
"Business -- The ORBCOMM System" represent the Company's estimates as of the
date hereof with respect to such markets. Such market descriptions and estimates
are based on a number of assumptions, some of which may be incorrect or may not
materialize, and unanticipated events may occur that could affect actual
business realized for ORBCOMM System services. Consequently, actual markets
should be expected to vary from the addressable markets discussed herein, and
these variations may be material.
 
DEPENDENCE ON KEY MANAGEMENT AND QUALIFIED PERSONNEL
 
     The Company's success will depend on the efforts of its management team and
its ability to attract and retain qualified management and personnel in the
future. The Company has no employment contract with any employee and is subject
to the loss of one or more key employees at any time. In addition, the Company
must rely on several employees of Orbital who play a key role in the performance
of Orbital's obligations under the Procurement Agreement. The Company has no
control over the relationship between Orbital and such employees. The Company
could be materially and adversely affected by the loss of one or more key
employees.
 
RELATIONSHIP BETWEEN STRATEGIC PARTNERS
 
     ORBCOMM is a partnership whose two partners, OCC and Teleglobe Mobile, each
hold a 50% Participation Percentage in the Company. Under the terms of the
ORBCOMM Partnership Agreement, substantially all actions by the Company require
the approval of at least a majority-in-interest (i.e., partners holding a
majority of the Participation Percentage in the Company). Therefore, under the
current ownership structure, if OCC and Teleglobe Mobile do not agree on a
course of action for the Company, a deadlock would occur. Generally, there is no
mechanism in the ORBCOMM Partnership Agreement or any other agreement for
resolving such a deadlock. The result of a deadlock between the strategic
partners could have a material adverse effect on the Company.
 
                                       25
<PAGE>   32
 
RISKS OF INTERNATIONAL OPERATIONS
 
   
     ORBCOMM expects to derive substantial revenues by providing international
communications services. Such operations are subject to certain risks such as
changes in domestic and foreign government regulations and communications
standards, licensing requirements, tariffs or taxes and other trade barriers,
exchange controls, and political and economic instability, including
fluctuations in the value of foreign currencies that may make payment in U.S.
dollars more expensive for foreign customers.
    
 
RISK THAT THE COMPANY IS TREATED AS A PUBLICLY TRADED PARTNERSHIP
 
   
     In general, a partnership is not a taxable entity for United States federal
income tax purposes. Certain partnerships ("publicly traded partnerships"),
however, are treated as corporations for federal tax purposes if interests in
the partnership are traded on an established securities market or on a secondary
market (or a substantial equivalent thereof). Treasury Regulations provide
generally that, for this purpose, an "interest in a partnership" includes any
financial instrument or contract the value of which is determined in whole or in
part by reference to the partnership (including the results of partnership
operations). The Regulations make an exception to this rule, however, for any
financial instrument or contract that (i) is treated as debt for federal tax
purposes and (ii) is not convertible into or exchangeable for an interest in the
capital or profits of the partnership and does not provide for a payment of
equivalent value. Such an instrument is not treated as an "interest in the
partnership" for purposes of these rules. The Company believes that the Senior
Notes are properly treated as debt for federal tax purposes because the Senior
Notes have a fixed maturity date, call for payment of interest on fixed payment
dates, are denominated as debt (rather than equity) of the Company, and
represent a claim on the Company's assets that is senior to that of certain
creditors, as well as that of the equity holders of the Company. Although the
Senior Notes provide for contingent interest that is based on the gross revenues
of the Company, the Company believes that such payments are not equivalent in
value to an interest in the capital or profits of the Company. Therefore, the
Company intends to report as a partnership, rather than as a publicly traded
partnership taxable as a corporation, for federal income tax purposes. If,
however, the Internal Revenue Service successfully took a contrary position, the
Company would be treated as a corporation for federal tax purposes, which would
reduce the amount of the Company's after-tax income available to meet its
obligations under the Senior Notes.
    
 
FRAUDULENT CONVEYANCE CONSIDERATIONS -- SUBSIDIARY GUARANTEES
 
     The obligations of the Company under the Senior Notes are guaranteed,
jointly and severally, by the Guarantors, including the Guarantees (the
"Subsidiary Guarantees") by ORBCOMM USA and ORBCOMM International (the
"Subsidiary Guarantors"). It is possible that creditors of the Subsidiary
Guarantors may challenge the Subsidiary Guarantees as a fraudulent conveyance
under relevant federal and state statutes, and, under certain circumstances
(including a finding that a Subsidiary Guarantor was insolvent at the time its
Subsidiary Guarantee was issued), a court could hold that the obligations of a
Subsidiary Guarantor under a Subsidiary Guarantee may be voided or are
subordinate to other obligations of a Subsidiary Guarantor. In addition, it is
possible that the amount for which a Subsidiary Guarantor is liable under a
Subsidiary Guarantee may be limited. The measure of insolvency for purposes of
the foregoing may vary depending on the law of the jurisdiction that is being
applied. Generally, however, a company would be considered insolvent if the sum
of its debts is greater than all of its property at a fair valuation or if the
present fair saleable value of its assets is less than the amount that will be
required to pay its probable liability on its existing debts as they become
absolute and mature. The Indenture provides that the obligations of the
Subsidiary Guarantors under the Subsidiary Guarantees will be limited to amounts
that will not result in the Subsidiary Guarantees being a fraudulent conveyance
under the applicable law. See "Description of Senior Notes -- Guarantees."
 
ABSENCE OF A PUBLIC MARKET
 
     The Old Notes are designated for trading in the PORTAL market, the National
Association of Securities Dealers Inc.'s screen-based automated market for
trading of securities eligible for resale under Rule 144A. The Exchange Notes
are a new issue of securities with no established trading market. Although the
Initial
 
                                       26
<PAGE>   33
 
Purchasers of the Old Notes have advised the Issuers that they currently intend
to make a market in the Exchange Notes, they are not obligated to do so and any
market-making activities with respect to the Exchange Notes may be discontinued
at any time without notice. The Issuers do not intend to list the Exchange Notes
on any national securities exchange or to seek admission thereof to trading in
the National Association of Securities Dealers Automated Quotation System.
Accordingly, there can be no assurance as to the development of any market, or
the liquidity of any market that may develop, for the Exchange Notes. If such a
market were to exist, no assurance can be given as to the trading prices of the
Exchange Notes. Future trading prices of Exchange Notes will depend on many
factors, including, among other things, prevailing interest rates, the Company's
results of operations and the market for similar securities, and, accordingly,
the Exchange Notes may trade at a discount from their principal amount.
 
FAILURE TO EXCHANGE NOTES
 
     The Exchange Notes will be issued in exchange for Old Notes only after
timely receipt by the Exchange Agent of such Old Notes, a properly completed and
duly executed Letter of Transmittal and all other required documents. Therefore,
holders of Old Notes desiring to tender such Old Notes in exchange for Exchange
Notes should allow sufficient time to ensure timely delivery. Neither the
Exchange Agent nor the Issuers is under any duty to give notification of defects
or irregularities with respect to tenders of Old Notes for exchange. Old Notes
that are not tendered, or are tendered but not accepted, will, following
consummation of the Exchange Offer, continue to be subject to the existing
restrictions upon transfer thereof. In addition, any holder of Old Notes who
tenders in the Exchange Offer for the purpose of participating in a distribution
of the Exchange Notes will be required to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction. Each broker-dealer that receives Exchange Notes for its own
account in exchange for Old Notes, where such Old Notes were acquired by such
broker-dealer as a result of market-making activities or any other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "Plan of Distribution." To the
extent that Old Notes are tendered and accepted in the Exchange Offer, the
trading market for untendered and tendered but unaccepted Old Notes could be
adversely affected. See "The Exchange Offer."
 
                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     The Old Notes were sold by the Issuers on August 7, 1996 (the "Closing
Date") to the Initial Purchasers. The Initial Purchasers subsequently placed the
Old Notes with qualified institutional buyers and institutional accredited
investors in transactions not requiring registration under the Securities Act or
applicable state securities laws, including sales pursuant to Rule 144A under
the Securities Act. As a condition to the sale of the Old Notes, the Issuers,
Guarantors and the Initial Purchasers entered into the Registration Rights
Agreement on August 7, 1996. Pursuant to the Registration Rights Agreement, the
Issuers agreed that, unless the Exchange Offer is not permitted by applicable
law or Commission policy, they would (i) file with the Commission a Registration
Statement under the Securities Act with respect to the Old Notes within 30 days
after the Closing Date, (ii) use their reasonable best efforts to cause such
Registration Statement to become effective under the Securities Act within 150
days after the Closing Date, and (iii) upon effectiveness of the Registration
Statement, commence the Exchange Offer, maintain the effectiveness of the
Registration Statement for at least 30 days (or a longer period if required by
law) and deliver to the Exchange Agent Exchange Notes in the same aggregate
principal amount as the Old Notes that were properly tendered by holders thereof
pursuant to the Exchange Offer. A copy of the Registration Rights Agreement has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part. The Registration Statement of which this Prospectus is a part is
intended to satisfy certain of the Issuers' obligations under the Registration
Rights Agreement.
 
                                       27
<PAGE>   34
 
RESALE OF THE EXCHANGE NOTES
 
     Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Issuers, the Issuers believe
that, with the exceptions discussed herein, Exchange Notes issued pursuant to
the Exchange Offer in exchange for Old Notes may be offered for resale, resold
and otherwise transferred by any person receiving the Exchange Notes, whether or
not that person is the holder (other than any such holder or such other person
that is an "affiliate" of the Issuers within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act; provided that (i) the Exchange Notes
are acquired in the ordinary course of business of that holder or such other
person, (ii) neither the holder nor such other person is engaging in or intends
to engage in a distribution of the Exchange Notes, and (iii) neither the holder
nor such other person has an arrangement or understanding with any person to
participate in the distribution of the Exchange Notes. However, the Issuers have
not sought, and do not intend to seek, their own no-action letter, and there can
be no assurance that the Commission's staff would make a similar determination
with respect to the Exchange Offer.
 
     Each broker-dealer that receives Exchange Notes for its own account in
exchange for Old Notes, where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes. The Letter of Transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Old Notes where such Old Notes were acquired by such broker-dealer
as a result of market-making or other trading activities. Pursuant to the
Registration Rights Agreement, the Company has agreed to make this Prospectus,
as it may be amended or supplemented from time to time, available to
broker-dealers for use in connection with any resale for a period of 180 days
after the Expiration Date. See "Plan of Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Issuers will accept any and all Old Notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the Expiration Date. The Issuers will issue $1,000 principal amount of Exchange
Notes in exchange for each $1,000 principal amount of outstanding Old Notes
accepted in the Exchange Offer. Holders may tender some or all of their Old
Notes pursuant to the Exchange Offer. However, Old Notes may be tendered only in
integral multiples of $1,000.
 
     The Exchange Notes will evidence the same debt as the Old Notes for which
they are exchanged, and are entitled to the benefits of the Indenture. The form
and terms of the Exchange Notes are substantially the same as the form and terms
of the Old Notes except that the Exchange Notes have been registered under the
Securities Act and hence will not bear legends restricting the transfer thereof.
 
   
     As of the date of this Prospectus, $170,000,000 aggregate principal amount
of Old Notes were outstanding. The Issuers have fixed the close of business on
October  , 1996, as the Record Date for the Exchange Offer for purposes of
determining the persons to whom this Prospectus, together with the Letter of
Transmittal, will initially be sent. As of the Record Date, there was one
registered holder of Old Notes. Holders of Old Notes do not have any appraisal
or dissenters' rights under the Delaware General Corporation Law or the
Indenture in connection with the Exchange Offer. The Issuers intend to conduct
the Exchange Offer in accordance with the provisions of the Registration Rights
Agreement and the applicable requirements of the Securities Act, the Exchange
Act and the rules and regulations of the Commission thereunder.
    
 
     The Issuers shall be deemed to have accepted validly tendered Old Notes
when, as and if the Issuers have given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering Holders
for the purpose of receiving the Exchange Notes from the Issuers. If any
tendered Old Notes are not accepted for exchange because of an invalid tender,
the occurrence of certain other events set forth herein or otherwise,
certificates for any such unaccepted Old Notes will be returned, without
expense, to the tendering Holder thereof as promptly as practicable after the
Expiration Date.
 
                                       28
<PAGE>   35
 
     Holders whose Old Notes are not tendered or are tendered but not accepted
in the Exchange Offer will continue to hold such Old Notes and will be entitled
to all the rights and preferences and subject to the limitations applicable
thereto under the Indenture. Following consummation of the Exchange Offer, the
Holders of Old Notes will continue to be subject to the existing restrictions
upon transfer thereof and the Issuers will have no other obligation to such
Holders of Old Notes to provide for the registration under the Securities Act of
the Old Notes held by them. The Old Notes are designated for trading in the
PORTAL market. To the extent Old Notes are tendered and accepted on the Exchange
Offer, the principal amount of outstanding Old Notes will decrease with a
resulting decrease in the liquidity of the market therefor. Following
consummation of the Exchange Offer, holders of Old Notes who were eligible to
participate in the Exchange Offer but who did not tender their Old Notes will
not be entitled to certain rights under the Registration Rights Agreement, and
such Old Notes will continue to be subject to certain restrictions on transfer.
Accordingly, the liquidity in the market for the Old Notes could be adversely
affected. No assurance can be given as to the liquidity of the trading market
for either the Old Notes or the Exchange Notes.
 
     Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Issuers will pay all charges and expenses,
other than certain applicable taxes, in connection with the Exchange Offer. See
"-- Fees and Expenses; Solicitation of Tenders."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean             , 1996, unless the
Issuers, in their sole discretion, extend the Exchange Offer, in which case the
term "Expiration Date" shall mean the latest date to which the Exchange Offer is
extended.
 
     To extend the Expiration Date, the Issuers will notify the Exchange Agent
of any extension by oral or written notice and will issue a press release or
other public announcement, each prior to 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date. Such
announcement may state that the Issuers are extending the Exchange Offer for a
specified period of time or on a daily basis until 5:00 p.m., New York City
time, on the date on which a specified percentage of Notes are tendered.
 
   
     The Issuers reserve the right (i) to delay accepting any Old Notes, to
extend the Exchange Offer or to terminate the Exchange Offer and not accept Old
Notes not previously accepted if any of the conditions set forth below under
"-- Certain Conditions to the Exchange Offer" shall not have been satisfied and
shall not have been waived by the Issuers, by giving oral or written notice of
such delay, extension or termination to the Exchange Agent, or (ii) to amend the
terms of the Exchange Offer in any manner deemed by it to be advantageous to the
Holders. Any such delay in acceptance, extension, termination or amendment will
be followed as promptly as practicable by oral or written notice thereof to the
Holders. If the Exchange Offer is amended in a manner determined by the Issuers
to constitute a material change, the Issuers will promptly disclose such
amendment by means of a prospectus supplement that will be distributed to all
Holders, and the Issuers will extend the Exchange Offer for a period of five to
ten business days, depending upon the significance of the amendment and the
manner of disclosure to Holders, if the Exchange Offer would otherwise expire
during such five to ten business day period. During any extension of the
Expiration Date, all Old Notes previously tendered will remain subject to the
Exchange Offer and may be accepted for exchange by the Issuers.
    
 
     Without limiting the manner in which the Issuers may choose to make public
announcement of any extension, amendment or termination of the Exchange Offer,
the Issuers shall have no obligation to publish, advertise, or otherwise
communicate any such public announcement, other than by making a timely release
to the Dow Jones News Service.
 
INTEREST ON THE SENIOR NOTES
 
     Fixed interest accrues on the Senior Notes at the rate of 14% per annum.
Fixed Interest and Revenue Participation Interest will be payable in cash
semiannually in arrears on each February 15 and August 15,
 
                                       29
<PAGE>   36
 
commencing on February 15, 1997. No interest will be payable on the Old Notes on
the date of the exchange for the Exchange Notes and therefore no interest will
be paid thereon to the Holders at such time.
 
PROCEDURES FOR TENDERING OLD NOTES
 
   
     The tender to the Company of Old Notes by a Holder thereof as set forth
below and the acceptance thereof by the Issuers will constitute a binding
agreement between the tendering Holder and the Issuers upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal. Except as set forth below, a Holder who wishes to tender
Old Notes for exchange pursuant to the Exchange Offer must transmit a properly
completed and duly executed Letter of Transmittal, including all other documents
required by such Letter of Transmittal, to the Exchange Agent at the address set
forth below under "-- Exchange Agent" on or prior to the Expiration Date. In
addition, either (i) certificates for such Old Notes must be received by the
Exchange Agent along with the Letter of Transmittal, (ii) a timely confirmation
of a book-entry transfer (a "Book-Entry Confirmation") of such Old Notes, if
such procedure is available, into the Exchange Agent's account at the Depositary
pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date, or (iii) the Holder
must comply with the guaranteed delivery procedures described below.
    
 
     THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY
IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH
RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION
DATE. NO LETTERS OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE ISSUERS.
HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined below)
unless the Old Notes surrendered for exchange pursuant thereto are tendered (i)
by a registered Holder of the Old Notes who has not completed the box entitled
"Special Insurance Instructions" or "Special Delivery Instructions" on the
Letter of Transmittal or (ii) for the account of an Eligible Institution (as
defined below). In the event that signatures on a Letter of Transmittal or a
notice of withdrawal, as the case may be, are required to be guaranteed, such
guarantee must be made by a firm which is a member of a registered national
securities exchange or a member of the National Association of Securities
Dealers, Inc. or by a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor institution" within
the meaning of Rule 17Ad-15 under the Exchange Act which is a member of one of
the recognized signature guarantee programs identified in the Letter of
Transmittal (collectively, "Eligible Institutions"). If Old Notes are registered
in the name of a person other than the person signing the Letter of Transmittal,
the Old Notes surrendered for exchange must be endorsed by, or be accompanied by
a written instrument or instruments of transfer or exchange, in satisfactory
form as determined by the Issuers in their sole discretion, duly executed by the
registered Holder with the signature thereon guaranteed by an Eligible
Institution.
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Issuers in their sole discretion, which determination shall be final and
binding. The Issuers reserve the absolute right to reject any and all tenders of
any particular Old Notes not properly tendered or to not accept any particular
Old Notes which acceptance might, in the judgment of the Issuers or their
counsel, be unlawful. The Issuers also reserve the absolute right in their sole
discretion to waive any defects of irregularities or conditions of the Exchange
Offer as to any particular Old Notes either before or after the Expiration Date
(including the right to waive the ineligibility of any Holder who seeks to
tender Old Notes in the Exchange Offer). The interpretation of the terms and
conditions of the Exchange Offer as to any particular Old Notes either before or
after the Expiration Date (including the Letter of Transmittal and instructions
thereto) by the Issuers shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with the tenders of Old
Notes for exchange must be cured within
 
                                       30
<PAGE>   37
 
such reasonable period of time as the Issuers shall determine. Neither the
Issuers, the Exchange Agent nor any other person shall be under any duty to give
notification of any defect or irregularity with respect to any tender of Notes
for exchange, nor shall any of them incur any liability for failure to give such
notification.
 
     If the Letter of Transmittal is signed by a person or persons other than
the registered Holder or Holders of Old Notes, such Old Notes must be endorsed
or accompanied by an appropriate bond power, in either case signed exactly as
the names of the registered Holder or Holders that appear on the Old Notes.
 
     If the Letter of Transmittal or any Old Notes or bond power is signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
person should so indicate when signing and, unless waived by the Issuers, proper
evidence satisfactory to the Issuers of their authority to so act must be
submitted.
 
     By tendering, each Holder (other than participating broker-dealers) will
represent to the Issuers that, among other things, (i) the Exchange Notes to be
acquired in exchange for Old Notes tendered in the Exchange Offer will have been
acquired in the ordinary course of business of such Holder or such other person
receiving such Exchange Notes, (ii) neither such Holder nor any such other
person has an arrangement or understanding with any person to participate in the
distribution of such Exchange Notes, (iii) such Holder or any such other person
acknowledges and agrees that any person who is a broker-dealer registered under
the Exchange Act or is participating in the Exchange Offer for the purposes of
distributing the Exchange Notes must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction of the Exchange Notes acquired by such person and cannot rely
on the position of the staff of the Commission set forth in certain no-action
letters, (iv) the Holder or any such other person understands that a secondary
resale transaction described in clause (iii) above and any resales of Exchange
Notes obtained by such Holder or such other person in exchange for Notes
acquired by such Holder or such other person directly from the Issuers should be
covered by an effective registration statement containing the selling
securityholder information required by Item 507 or Item 508, as applicable, of
Regulation S-K of the Commission and (v) neither the Holder nor any such other
person is an "affiliate," as defined in Rule 405 under the Securities Act, of
the Issuers. If the Holder or such other person receiving the Exchange Notes is
a broker-dealer that will receive Exchange Notes for its own account in exchange
for Notes that were acquired as a result of market-making activities or other
trading activities, the Holder or such other person is required to acknowledge
in the Letter of Transmittal that it will deliver a prospectus in connection
with any resale of such Exchange Notes; however, by so acknowledging and by
delivering a prospectus, the Holder or such other person will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES; RETURN OF OLD
NOTES
 
     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Issuers will accept, promptly after the Expiration Date, all Old Notes
properly tendered and will issue the Exchange Notes promptly after acceptance of
the Old Notes. See "-- Certain Conditions to the Exchange Offer" below. For
purposes of the Exchange Offer, the Issuers shall be deemed to have accepted
properly tendered Old Notes for exchange when and if the Issuers have given oral
or written notice thereof to the Exchange Agent.
 
     In all cases, issuance of Exchange Notes for Old Notes that are accepted
for exchange pursuant to the Exchange Offer will be made only after timely
receipt by the Exchange Agent of certificates for such Old Notes or a timely
Book-Entry Confirmation of transfer of such Notes into the Exchange Agent's
account at the Depositary, a properly completed and duly executed Letter of
Transmittal and all other required documents. If any tendered Old Notes are not
accepted for any reason set forth in the terms and conditions of the Exchange
Offer or if certificates representing Old Notes are submitted for a greater
principal amount than the Holder desires to exchange, such unaccepted, withdrawn
or non-exchanged Old Notes will be returned without expense to the tendering
Holder thereof (or, in the case of Old Notes tendered by book-entry transfer
into the Exchange Agent's account at the Depositary pursuant to the book-entry
transfer procedures described below, such non-exchanged Old Notes will be
credited to an account maintained with the Depositary) as promptly as
practicable after the expiration or termination of the Exchange Offer.
 
                                       31
<PAGE>   38
 
BOOK-ENTRY TRANSFER
 
   
     The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Depositary for purposes of the Exchange Offer within two
business days after the date of this Prospectus, and any financial institution
that is a participant in the Depositary's systems may make book-entry delivery
of Old Notes by causing the Depositary to transfer such Old Notes into the
Exchange Agent's account at the Depositary in accordance with the Depositary's
procedure for transfer. However, although delivery of Old Notes may be effected
through book-entry transfer at the Depositary, the Letter of Transmittal or a
facsimile thereof, with any required signature guarantees and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address set forth below under "-- Exchange Agent" on or prior to
the Expiration Date or the guaranteed delivery procedures described below must
be complied with.
    
 
     The DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through the DTC. To accept the Exchange Offer through
ATOP, participants in DTC must send electronic instructions to the DTC through
the DTC's communication system in place of sending a signed, hard copy Letter of
Transmittal. The DTC is obligated to communicate those electronic instructions
to the Exchange Agent. To tender Old Notes through ATOP, the electronic
instructions sent to the DTC and transmitted by the DTC to the Exchange Agent
must contain the character by which the participant acknowledges its receipt of
and agrees to be bound by the Letter of Transmittal.
 
GUARANTEED DELIVERY PROCEDURES
 
     If a registered Holder of the Old Notes desires to tender such Old Notes
and the Old Notes are not immediately available, or time will not permit such
Holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is made
through an Eligible Institution, (ii) prior to the Expiration Date, the Exchange
Agent receives from such Eligible Institution a properly completed and duly
executed Letter of Transmittal (or a facsimile thereof) and Notice of Guaranteed
Delivery, substantially in the form provided by the Issuers (by telegram, telex,
facsimile transmission, mail or hand delivery), setting forth the name and
address of the Holder of Old Notes and the amount of Old Notes tendered, stating
that the tender is being made thereby and guaranteeing that within three
business days after the date of execution of the Notice of Guaranteed Delivery,
the certificates of all physically tendered Old Notes, in proper form for
transfer, or a Book-Entry Confirmation, as the case may be, and any other
documents required by the Letter of Transmittal will be deposited by the
Eligible Institution with the Exchange Agent and (iii) the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and all other documents required by the Letter
of Transmittal, are received by the Exchange Agent within three business days
after the date of execution of the Notice of Guaranteed Delivery.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWAL RIGHTS
 
     Tenders of Old Notes may be withdrawn at any time prior to the Expiration
Date.
 
     For a withdrawal to be effective, a written or facsimile notice of
withdrawal must be received by the Exchange Agent at the address set forth below
under "-- Exchange Agent." Any such notice of withdrawal must (i) specify the
name of the person having tendered the Old Notes to be withdrawn, (ii) identify
the Old Notes to be withdrawn (including the certificate number or numbers and
the principal amount of Old Notes to be withdrawn), (iii) be signed by the
Holder in the same manner as the signature on the Letter of Transmittal by which
such Old Notes were tendered (including any required signature guarantees) and
(iv) specify the name in which such Notes are to be registered if different from
that of the withdrawing Holder. If Old Notes have been tendered pursuant to the
procedure for book-entry described above, any notice of withdrawal must specify,
in lieu of certificate numbers, the name and number of the account at the
Depositary to be credited with the withdrawn Old Notes and otherwise comply with
the procedures of such facility. All questions as to
 
                                       32
<PAGE>   39
 
the validity, form and eligibility (including time of receipt) of such notices
will be determined by the Issuers, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for exchange for purposes of the Exchange Offer. Any Old
Notes which have been tendered for exchange but which are not exchanged for any
reason will be returned to the Holder thereof without cost to such Holder (or,
in the case of Old Notes tendered by book-entry transfer into the Exchange
Agent's account at the Depositary pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account maintained with
the Depositary for the Old Notes) as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offer. Properly withdrawn Old
Notes may be retendered by following one of the procedures described under
"-- Procedures for Tendering Old Notes" above at any time on or prior to the
Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other term of the Exchange Offer, the Issuers'
obligation to accept for exchange, or exchange Exchange Notes for, any Old Notes
not theretofore accepted for exchange is subject to the following conditions:
 
          (a) no action or proceeding having been instituted or threatened in
     any court or by or before any governmental agency with respect to the
     Exchange Offer which, in the judgment of the Issuers, might impair the
     ability of the Issuers to proceed with the Exchange Offer or have a
     material adverse effect on the Issuers and there shall not have occurred
     any material adverse development in any existing action or proceeding with
     respect to the Issuers or any of their subsidiaries; and
 
          (b) there shall not have been any material change, or development
     involving a prospective change, in the business or financial affairs of the
     Issuers or any of their subsidiaries which, in the judgment of the Issuers,
     would materially impair the Issuers' ability to consummate the Exchange
     Offer or have a material adverse impact on the Issuers if the Exchange
     Offer is consummated; and
 
          (c) there shall not have been proposed, adopted or enacted any law,
     statute, rule or regulation which, in the judgment of the Issuers, might
     materially impair the ability of the Issuers to proceed with the Exchange
     Offer or have a material adverse effect on the Issuers if the Exchange
     Offer is consummated; and
 
          (d) all governmental approvals which the Issuers shall deem necessary
     for the consummation of the Exchange Offer as contemplated hereby shall
     have been obtained.
 
     If the Issuers determine in good faith that any of the conditions are not
met, the Issuers may (i) refuse to accept any Old Notes and return all tendered
Old Notes to exchanging Holders, (ii) extend the Exchange Offer and retain all
Old Notes tendered prior to the expiration of the Exchange Offer, subject,
however, to the rights of Holders to withdraw such Old Notes (see "-- Withdrawal
Rights") or (iii) waive certain of such unsatisfied conditions with respect to
the Exchange Offer and accept all properly tendered Old Notes which have not
been withdrawn. If such waiver constitutes a material change to the Exchange
Offer, the Issuers will promptly disclose such waiver by means of a prospectus
supplement that will be distributed to all Holders.
 
     Holders have certain rights and remedies against the Issuers under the
Registration Rights Agreement, including the right to receive liquidated
damages, in the event that (i) an Exchange Offer Registration Statement has not
been filed with the Commission on or prior to 30 days following the Old Notes
Offering, (ii) on or prior to 150 days prior to the Old Notes Offering such
Exchange Offer Registration Statement is not declared effective, (iii) on or
prior to 180 days following the Old Notes Offering the Exchange Offer is not
consummated, or (iv) applicable law or interpretations of the Commission
prohibit a Holder from participating in the Exchange Offer or for any reason the
Exchange Offer is not consummated within 180 days of the Old Notes Offering and
a Shelf Registration Statement is not filed or declared effective within the
time provided by the Registration Rights Agreement for such filing or
declaration, such liquidated damages to be payable in cash semiannually in
arrears, and to accrue at a rate per annum equal to an additional one quarter of
one percent (0.25%) of the principal amount of the Senior Notes, which rate will
increase by one quarter of
 
                                       33
<PAGE>   40
 
one percent (0.25%) for each 90-day period that such Liquidated Damages continue
to accrue, with an aggregate maximum increase in the interest rate per annum
equal to one percent (1.00%).
 
     The foregoing conditions are for the benefit of the Issuers and may be
asserted by the Issuers in good faith regardless of the circumstances giving
rise to such condition or may be waived by the Issuers in whole or in part at
any time and from time to time in its discretion. The failure by the Issuers at
any time to exercise the foregoing rights shall not be deemed a waiver of any
such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.

     DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF
INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A
VALID DELIVERY.
 
FEES AND EXPENSES; SOLICITATION OF TENDERS
 
     The expenses of soliciting tenders will be borne by the Issuers. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers and regular
employees of the Issuers and their affiliates.
 
     The Issuers have not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Issuers, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Issuers and are estimated in the aggregate to be approximately
$       and include registration fees, fees and expenses of the Exchange Agent
and Trustee, accounting and legal fees and printing costs, among others.
 
     The Issuers will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered holder of the Old Notes
tendered, or if tendered Old Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Old Notes pursuant to the
Exchange Offer, then the amount of any such other taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted
 
                                       34
<PAGE>   41
 
with the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering Holder.
 
     No person has been authorized to give any information or to make any
representations in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been authorized by the Issuers. Neither the
delivery of this Prospectus nor any exchange made hereunder shall, under any
circumstances, create any implication that there has been no change in the
affairs of the Issuers since the respective dates as of which information is
given herein. The Exchange Offer is not being made to (nor will tenders be
accepted from or on behalf of) Holders in any jurisdiction in which the making
of the Exchange Offer or the acceptance thereof would not be in compliance with
the laws of such jurisdiction.
 
ACCOUNTING TREATMENT
 
     The Exchange Notes will be recorded at the same carrying value as the Old
Notes, which is face value, as reflected in the Issuers' accounting records on
the date of the exchange. Accordingly, no gain or loss for accounting purposes
will be recognized. The costs of the Exchange Offer will be expensed over the
term of the Exchange Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Old Notes who do not exchange their Old Notes for Exchange Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon. In general,

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     In 1990, Orbital formed OCC to develop and operate the first global two-way
data and messaging communications system. In March 1992 and May 1993, the FCC
awarded OCC experimental licenses to develop and test a limited Little LEO
service. These licenses permitted the launch of two satellites, the construction
of two Earth stations and the provision of service to up to 1,000 Subscriber
Communicators. Following receipt of these experimental licenses, OCC sought a
strategic equity partner who could offer both financial and communications
experience, and in 1993, formed ORBCOMM with Teleglobe Mobile, an affiliate of
Teleglobe. Teleglobe Mobile agreed to acquire 50% of ORBCOMM in a two-stage
transaction. Teleglobe subsequently sold 30% of its interest in Teleglobe Mobile
to TRI for $43.9 million. In September 1995, Teleglobe Mobile agreed to invest
an additional $75 million, bringing its total capital commitment to
approximately $85 million. At that time, OCC committed approximately an
additional $10 million to the project, bringing its total investment commitment
to approximately $75 million. As of August 7, 1996, Teleglobe Mobile and OCC
have invested an aggregate of approximately $160 million in the ORBCOMM project.
 
     On October 20, 1994, OCC was granted authority by the FCC to construct,
launch and operate 36 satellites for the purpose of providing two-way data and
message communications and position determination services.
 
   
     In April 1995, the first two satellites comprising the ORBCOMM System were
deployed. After experiencing initial operating anomalies related to satellite
positioning and gateway-to-satellite communications, the satellites are
functional. By December 1995, ORBCOMM had completed construction and testing of
various network operating systems, substantially completed the U.S. Gateway and
transmitted test messages via prototype Subscriber Communicators. On February 1,
1996, the ORBCOMM System commenced commercial intermittent operations in the
United States using its first two satellites. The ORBCOMM System is currently
providing commercial intermittent data communications services to the
environmental and oil and gas industries in the United States.
    
 
     On August 7, 1996, ORBCOMM completed the Old Notes Offering.
 
ORGANIZATIONAL STRUCTURE; FINANCIAL REPORTING
 
     Simultaneous with the formation of ORBCOMM, OCC and Teleglobe Mobile formed
two marketing partnerships, ORBCOMM USA and ORBCOMM International (collectively,
the "Marketing Partnerships"), with the exclusive right to market the ORBCOMM
System in the United States and internationally, respectively. ORBCOMM is a 98%
general partner in each of the Marketing Partnerships, while OCC and Teleglobe
Mobile control the remaining 2% of ORBCOMM USA and ORBCOMM International,
respectively. OCC retains control over the applicable FCC licenses and the
ORBCOMM System, consistent with FCC regulations.
 
     Pursuant to the terms of the Partnership Agreements: (i) OCC and Teleglobe
Mobile share equal responsibility for the operational and financial affairs of
ORBCOMM; (ii) OCC generally controls the operational and financial affairs of
ORBCOMM USA; and (iii) Teleglobe Mobile generally controls the operational and
financial affairs of ORBCOMM International. Since OCC and Teleglobe Mobile have
effective control over ORBCOMM USA and ORBCOMM International, respectively,
ORBCOMM accounts for the Marketing Partnerships using the equity method of
accounting. ORBCOMM does not consolidate, and therefore does not report on its
financial statements, ORBCOMM USA's and ORBCOMM International's actual assets,
liabilities and operating revenues and expenses. Instead, ORBCOMM's pro rata
share of the results of the Marketing Partnerships are recorded under the
caption "Equity in Earnings (Losses) of Affiliates" in ORBCOMM's financial
statements. Correspondingly, ORBCOMM's investment in the Marketing Partnerships
is carried at cost, subsequently adjusted for the pro rata share of net income
and losses, additional capital contributions and distributions under the caption
"Investments in and Advances to
 
                                       38
<PAGE>   45
 
Affiliates." Holders of Senior Notes are also encouraged to refer to the
financial statements of both ORBCOMM USA and ORBCOMM International included
elsewhere in this Prospectus.
 
   
     ORBCOMM USA pays to OCC an Output Capacity Charge that is a quarterly fee
equal to 23% of its total aggregate revenues for such calendar quarter in
exchange for the exclusive right to market, sell, lease and franchise all
ORBCOMM System output capacity in the United States and exclusive use of the
System Assets located in the United States. In consideration of the construction
and financing of the System Assets, OCC, in turn, pays to the Company a System
Charge that is a quarterly fee equal to the Output Capacity Charge minus 1.15%
of Total Aggregate Revenues, defined as the total of ORBCOMM USA and ORBCOMM
International total system service revenues.
    
 
   
     ORBCOMM International pays to Teleglobe Mobile an International Output
Capacity Charge equal to 23% of its total aggregate revenues for a calendar
quarter in exchange for the exclusive right to market, sell, lease and franchise
all ORBCOMM System output capacity outside the United States. In consideration
of the grant to Teleglobe Mobile of the exclusive right to market, sell, lease
and franchise all ORBCOMM System output capacity outside the United States,
Teleglobe Mobile, in turn, pays to the Company an International System Charge
that is a quarterly fee equal to the International Output Capacity Charge minus
1.15% of Total Aggregate Revenues as defined above.
    
 
SERVICE ROLL-OUT
 
     The roll-out of ORBCOMM System services will occur in two stages. In the
United States, it is currently possible to serve several market segments that
can benefit from intermittent service, such as oil and gas pipeline monitoring,
certain environmental monitoring, and tracking and positioning applications. As
additional satellites are added to the constellation, it will become possible to
serve additional market segments such as certain messaging applications that
require real time services.
 
   
     Commercial intermittent service commenced in the United States in February
1996. Service outside the United States will be provided as International
Licensees receive regulatory approval and build network ground systems.
    
 
REVENUE
 
     Currently, during the period of commercial intermittent service, ORBCOMM
USA is building an initial base of subscribers in the United States through the
negotiation and execution of agreements with Resellers. The Resellers purchase
ORBCOMM System services directly from ORBCOMM USA and resell these services to
end-users in a specific industry and/or market.
 
     In the United States, service pricing is based on many variables, including
the availability and cost of substitute services, the cost of providing service
and the nature of the user application. Pricing generally incorporates an
initial registration charge, a recurring monthly charge for access to the
ORBCOMM System and usage charges based on the customer's activity. In charging
for usage, the Company has developed a pricing structure in the United States
that suits the usage patterns for the initial vertical markets addressed by the
existing two-satellite system. Priority and other real time messaging pricing
will be developed as the full deployment of satellites in the ORBCOMM System
occurs. It is likely that multiple pricing alternatives will be offered in the
United States including peak/off-peak, volume discounts, and annual contract
commitment options.
 
     The Company has a standard Service License Agreement for execution by
International Licensees outside the United States. The International Licensees
will be responsible for obtaining all necessary licenses and approvals for use
of the ORBCOMM System in their territory. Certain International Licensees will
pay to ORBCOMM International a fixed fee in exchange for exclusive rights for a
specified service territory. In addition, International Licensees will pay a
monthly Satellite Usage Fee based on the greater of a percentage of gross
operating revenues and a data throughput fee. On the execution of a Service
License Agreement, International Licensees will be required to purchase a
Gateway from ORBCOMM or share a closely located Gateway operated by ORBCOMM USA
or another International Licensee.
 
                                       39
<PAGE>   46
 
     Retail pricing in their respective territories will be at the discretion of
the International Licensees, and is expected to vary from country to country to
reflect variations in economic conditions, the availability of substitute
services, local customs, and government policy as required to be competitive
with other services.
 
OPERATING EXPENSES
 
     As discussed above, the Company owns and operates the assets that comprise
the ORBCOMM System. Satellite-based communications systems are characterized by
high up-front capital expenditures and relatively low marginal costs for
providing service. ORBCOMM has been depreciating the assets, recording a
depreciation charge in its statement of income and expenses, beginning in
January 1996. Additionally, ORBCOMM incurs, and reports in its financial
statements, engineering and other operating expenses associated with the actual
operation of the ORBCOMM System.
 
RESULTS OF OPERATIONS -- ORBCOMM
 
     ORBCOMM commenced commercial intermittent service in the United States on
February 1, 1996 and has generated nominal revenues and negative cash flow to
date. ORBCOMM's activities have focused primarily on the acquisition of
regulatory approvals for operation of the ORBCOMM System, design, construction
and deployment of its initial satellites and associated network systems,
negotiation of domestic reseller agreements, identification of potential
International Licensees in countries outside the United States, identification
and authorization of Subscriber Communicator manufacturers and hiring of
management and other key personnel. ORBCOMM expects to continue to generate
negative cash flow until the system is fully operational, planned for 1998.
 
     Income.  In 1995, ORBCOMM received a nonrefundable fee from a potential
International Licensee. The Company recognized this nonrefundable fee ratably
over the term of the relevant agreement. No such fees were received in earlier
periods or in the six months ended June 30, 1996.
 
     In late 1994, the Company received a $5 million secured loan to help
finance a portion of the ORBCOMM System. The Company recognized interest income
on the invested portion of the loan proceeds of approximately $35,000 and
$17,000 for the six-month periods ended June 30, 1995 and 1996, respectively,
and approximately $58,000 for the year ended December 31, 1995 (none for the
year ended December 31, 1994). Interest expense related to the secured loan has
been capitalized as part of the historical cost of the ORBCOMM System.
 
   
     Expenses.  As discussed above, ORBCOMM is in its development stage and does
not anticipate emerging from the development stage until early 1998. During the
construction phase of the ORBCOMM System, ORBCOMM has capitalized all
construction costs, consisting primarily of satellites, launch vehicles and the
U.S. ground segment acquired from Orbital. Research and development expenses and
selling, general and administrative costs have been expensed in the period
incurred.
    
 
     Once the ORBCOMM System began commercial operations on February 1, 1996,
ORBCOMM incurred approximately $2,275,000 of administrative expenses in the six
months ended June 30, 1996 (none during the six months ended June 30, 1995).
ORBCOMM incurred approximately $9,000 and $50,000 of administrative expenses
during the years ended December 31, 1994 and 1995, respectively (none during
1993).
 
     ORBCOMM incurred approximately $2,085,000 of ORBCOMM System engineering
expenses in the six months ended June 30, 1996 as commercial service in the
United States began (none during the 1995 six-month period). ORBCOMM also
incurred approximately $3,042,000 in ORBCOMM System depreciation expense during
the 1996 six-month period, as the ORBCOMM System became available for service in
early 1996 (none during the 1995 six-month period).
 
     Equity in Earnings (Losses) of Affiliates.  ORBCOMM recognized its share of
ORBCOMM USA's and ORBCOMM International's losses, consisting primarily of
marketing expenses, of approximately $1,610,000 in the first half of 1996 (none
in the first half of 1995) and approximately $853,000 for the year
 
                                       40
<PAGE>   47
 
ended December 31, 1995 (none in earlier years). Each of ORBCOMM USA and ORBCOMM
International formally began their marketing efforts in 1995 in anticipation of
commercial service in 1996.
 
RESULTS OF OPERATIONS -- ORBCOMM USA
 
     Income.  In 1993, 1994 and 1995, ORBCOMM USA performed marketing activities
for the U.S. market pursuant to a contract with OCC, whereby OCC reimbursed
ORBCOMM USA for all marketing costs incurred. Accordingly, ORBCOMM USA
recognized contract revenues of approximately $749,000, $2,093,000 and
$1,360,000 from June 30, 1993 (date of inception) through December 31, 1993 and
the years ended 1994 and 1995, respectively and $886,000 during the six months
ended June 30, 1995 (none during the six months ended June 30, 1996). During the
first half of 1996, ORBCOMM USA recognized its first revenues relating to the
provision of services through the ORBCOMM System, less than $51,000.
 
     Expenses.  ORBCOMM USA incurred approximately $1,241,000 of marketing and
administrative expenses and $48,000 of cost of product sales in the six months
ended June 30, 1996, once the ORBCOMM System began operations. Pursuant to the
contract with OCC discussed above, ORBCOMM USA incurred contract marketing costs
of approximately $749,000, $2,093,000 and $2,231,000 from June 30, 1993 (date of
inception) through December 31, 1993 and the years ended December 31, 1994 and
1995, respectively and $886,000 during the six months ended June 30, 1995.
 
RESULTS OF OPERATIONS -- ORBCOMM INTERNATIONAL
 
     Expenses.  ORBCOMM International incurred approximately $405,000 of
administrative expenses in the six months ended June 30, 1996 (none during the
1995 six-month period or earlier years). International marketing efforts are
expected to increase during 1996 and 1997 in anticipation of the completion of
the ORBCOMM System.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     The development of the Company's business, launch of the initial two
satellites and construction of the network operations center and U.S. Gateway
have resulted in substantial capital expenditures during the past several years.
Capital expenditures by the Company were approximately $11 million and $29
million during the six months ended June 1995 and 1996, respectively, and $44
million, $25 million and $38 million from June 30, 1993 (date of inception)
through December 31, 1993 and the years ended December 31, 1994 and 1995,
respectively. The Company expects that it will continue to have substantial
capital expenditure requirements in the future, including approximately $45
million during the remainder of 1996 expected to be payable under the
Procurement Agreement.
    
 
   
     A combination of operating losses and substantial capital expenditures
related to the development of the ORBCOMM System has resulted in negative cash
flow since 1994. Funding of this cash flow deficiency has been accomplished
through capital contributions from OCC and Teleglobe Mobile and the MetLife
Note. ORBCOMM expects to have to continue to fund operating losses as the
Company develops and expands its business. Following August 15, 1998, interest
expense on the Senior Notes will represent a significant cash requirement for
the Company. OCC and Teleglobe Mobile have invested approximately $75 million
and $85 million, respectively, in exchange for their Participation Percentage in
ORBCOMM, ORBCOMM USA and ORBCOMM International.
    
 
   
     The total cost of the construction and deployment of the ORBCOMM System is
estimated to be approximately $258 million. Of this amount, approximately $202
million will be used for the satellite constellation, ground spares and launch
services, approximately $30 million will be used for the U.S. ground segment,
approximately $8 million will be used for insurance and approximately $18
million will be used for other costs. As of June 30, 1996, approximately $136
million of this amount had been expended. The Company believes that the net
proceeds of the Old Notes Offering and the capital contributions of the
partners, together with expected cash from operations, will be sufficient to
fund the Company's operations through at least the first quarter of 1998, when
full deployment of the ORBCOMM System is planned to have occurred. The Company
believes that a significant portion of cash from operations through the first
quarter of 1998 will be generated through international license fees obtained by
converting a number of its existing and anticipated Memoranda of Understanding
into Service License Agreements. Additional funds may be necessary in the event
of a delay with respect to the deployment of the full constellation or market
acceptance of ORBCOMM services, including as a result of delays in the receipt
of international license fees or a sales cycle longer than anticipated, cost
overruns or any shortfall in estimated levels of estimated cash flow, or to meet
unanticipated expenses. There can be no assurance that additional capital will
be available for any of the foregoing purposes on favorable terms or on a timely
basis, if at all.
    
 
   
     The Senior Notes contain a revenue participation feature providing for
payment by the Company, on each interest payment date, of interest in an
aggregate amount equal to 5.0% of System Revenue for the six-month period ending
on December 31 or June 30 most recently completed prior to such interest payment
date. See "The Exchange Offer -- Summary of Terms of the Exchange Notes." The
Company is not required to pay any Revenue Participation Interest, however,
until the Credit Parties' Fixed Charge Coverage Ratio for the four consecutive
fiscal quarters last completed prior to such interest payment date equals or
exceeds 2.0:1. See "Description of Notes -- Principal, Maturity and Interest."
Once this ratio is exceeded, the Company will have to pay additional interest on
the Senior Notes beyond the base rate of 14%, which will negatively impact the
Company's liquidity.
    
 
   
     There are no distributions required to be made to the Partners of the
Company other than a minimum annual distribution required by the ORBCOMM
Partnership Agreement in the amount of (i) 40%, multiplied by the lesser of (a)
such Partner's distributive share of the Partnership's taxable income for the
preceding year, and (b) the excess, if any, of cumulative Net Income (as
defined) over cumulative Net Loss (as defined) allocated to such Partner since
the inception of the Partnership. All other distributions are to be made at the
discretion of the Partners. See "The Partnership Agreement -- Allocations and
Distributions." Pursuant to the covenants contained in the Indenture, no
additional cash distributions are permitted to be made to the Partners of the
Company other than those distributions that satisfy the requirements of the
    
 
                                       42
<PAGE>   49
 
   
various limitations on Restricted Payments contained in the Indenture. To the
extent that such requirements are met and the Partners receive additional cash
distributions from the Company beyond that required by the ORBCOMM Partnership
Agreement, this could negatively impact the Company's liquidity.
    
 
LOAN AGREEMENT WITH METLIFE CAPITAL CORPORATION
 
   
     Under the terms of the MetLife Note, MetLife loaned $5 million to the
Company, and in connection therewith the Company granted to MetLife a security
interest in certain equipment of the Company. The MetLife Note is guaranteed by
Orbital. As of June 30, 1996, approximately $3.7 million was outstanding under
the MetLife Note. The Senior Notes rank pari passu in right and priority of
payment with the MetLife Note, except to the extent of the collateral securing
such MetLife Note. See "Description of Notes -- General."

                                    BUSINESS
 
   
     The Company is establishing the first commercial LEO satellite-based mobile
data and messaging communications system that will be available on a global
basis. The ORBCOMM System, planned to be fully deployed in early 1998, is
designed to provide reliable, low-cost, two-way global data and messaging
communications through a constellation of 28 LEO satellites and a complement of
associated ground infrastructure situated around the world. The Company believes
that there is significant global demand for its low-cost data and messaging
communications services. Major target markets include worldwide mobile asset
tracking; remote industrial monitoring and control applications; environmental
data collection; and real time person-to-person and machine-to-machine
communications, including two-way Internet email communications and recreational
and business messaging. The Company anticipates that the ORBCOMM System will be
used: (i) as a complement to existing or proposed tower-based services such as
paging and other narrowband PCS services, providing geographic coverage in areas
these systems are unable to reach; and (ii) to enhance data applications
currently being provided through the PSTN and the PSDN. In addition, the Company
expects that the introduction of its low-cost, reliable data and messaging
communications will lead to the development of new applications and services.
    
 
     The Company currently offers commercial intermittent data communications
services in the United States through its existing network, which consists of
two LEO satellites launched in April 1995 and related U.S. ground
infrastructure. When fully deployed, the ORBCOMM System is designed to provide
data and short, alphanumeric paging-like messaging communications coverage
virtually anywhere on the Earth's surface in a reliable and cost-effective
manner. In contrast to Big LEO systems, which are designed primarily for voice
applications and require satellite communications systems that are estimated to
cost in excess of $2 billion to construct and deploy, the ORBCOMM System, which
is a Little LEO system, is focused on data communications and messaging
applications and will be constructed and deployed for approximately $258 million
(with additional amounts needed to fund initial operation of the ORBCOMM System
and certain debt service obligations). The ORBCOMM System is designed to address
the substantial existing and growing demand for communications services
worldwide, without the high cost and geographic and technical limitations
imposed by other communications systems.
 
     In October 1994, a subsidiary of Orbital became the first company to be
awarded FCC authority to construct, launch and operate a LEO satellite-based
data and messaging communications system in the United States. Today, the
ORBCOMM System is the only commercial Little LEO system that is fully licensed
for all segments of its system in the United States. Certain portions of the
radio spectrum were allocated by the ITU for use by Little LEO satellite
systems, such as the ORBCOMM System, on an international basis in 1992. The
Company intends to enter into agreements with International Licensees, who will
pursue the requisite local regulatory approvals for each foreign country in
which the ORBCOMM System will operate and who will pay fees for access to the
ORBCOMM System in their territory.
 
   
     In 1995, in addition to the successful launch of the first two ORBCOMM
System satellites, the Company: (i) completed initial development and
construction of the ground infrastructure located in the United States and
associated network control systems; and (ii) tested prototype Subscriber
Communicators. The two ORBCOMM System satellites and four U.S. Earth stations
currently are providing data communications services, focused on environmental
and industrial monitoring applications for the U.S. environmental and oil and
gas industries and asset and cargo tracking applications for the U.S. government
and commercial entities, with additional tracking and positioning applications
targeted for the near future. As of June 30, 1996, the ORBCOMM System had
transmitted during testing and commercial operations in excess of one million
messages and successfully completed extensive internal and third-party testing,
including a rigorous demonstration program conducted by the DoD as part of its
Joint Warrior Interoperability Demonstration '95 ("JWID"). This demonstration,
sponsored annually by the Department of Defense, is designed to demonstrate new
technologies in a simulated operational environment. During JWID '95, Army Space
Command successfully used the ORBCOMM System to demonstrate remote tracking of
vehicles and email messaging capabilities, with over one thousand messages,
emails and faxes sent over a four-week period.
    
 
                                       44
<PAGE>   51
 
     To use the ORBCOMM System, a user creates a text message utilizing a
computer or Subscriber Communicator device, which message is sent to the nearest
ORBCOMM System satellite and delivered to an ORBCOMM Earth station, which
supports communication with the satellites, and then to the Gateway Switching
System, which processes the messages. Within the Gateway, the message is
processed using a combination of ORBCOMM-developed and commercial email
software, and sent on to its ultimate destination. If desired, an
acknowledgement message is returned to the sender. The final delivery may be to
another Subscriber Communicator or may make use of public/private X.25 data
networks, the Internet, or text-to-fax conversion.
 
   
     The Company intends to distribute its services globally in a cost-effective
manner through the use of Resellers in the United States and International
Licensees around the world. The Company is in the process of negotiating and
signing agreements with Resellers, each of whom will be responsible for
marketing to end customers in a specific industry and/or market and generally is
expected to develop software applications to facilitate use of ORBCOMM System
services by such industry or market segment. To date, 25 reseller agreements
have been signed with companies including Arinc, Inc., Boatracs, Inc., Corexco
Consulting Services, Inc., Globitrac, Inc., IWL Communications, Inc., QUALCOMM,
Incorporated and the Stevens Water Monitoring Division of Leupold & Stevens,
Inc. The Company has signed ten Memoranda of Understanding with potential
International Licensees and is in active negotiations with nine other potential
International Licensees; taken together, these 19 potential International
Licensees represent approximately 35 countries around the world. The Company
intends to convert substantially all its existing Memoranda of Understanding
into Service License Agreements during the next three to 18 months. In addition,
the Company has signed three Service License Agreements with International
Licensees. On October 15, 1996, ORBCOMM signed a Service License Agreement with
ORBCOMM Europe, a consortium of European companies, which has been given the
exclusive right to market services using the ORBCOMM System to approximately 40
European countries. ORBCOMM has also executed a Service License Agreement with
ORBCOMM Canada, which is controlled by Teleglobe, and which has been given the
exclusive right to market services in Canada using the ORBCOMM System. The third
Service License Agreement was executed with Celcom, a wholly owned subsidiary of
TRI, and grants Celcom the exclusive right to market services in Malaysia,
Singapore and Brunei.
    
 
   
     ORBCOMM is a limited partnership formed in 1993 to develop, construct,
operate and market the ORBCOMM System. The general and limited partnership
interests in ORBCOMM are held by each of OCC, a subsidiary of Orbital, and
Teleglobe Mobile, a Delaware general partnership whose interests are wholly
owned on an indirect basis by Teleglobe and TRI. OCC and Teleglobe Mobile have
invested approximately $160 million in the ORBCOMM project. The Company believes
that such equity investment, together with the proceeds of the Old Notes
Offering and cash expected to be generated from operations, will be sufficient
to fund the ORBCOMM System, including: (i) all capital expenditures necessary to
deploy the ORBCOMM System; and (ii) all required working capital until at least
the first quarter 1998, when full deployment of the ORBCOMM System is planned to
have occurred. There can be no assurance, however, that additional capital will
not be necessary.
    
 
BUSINESS STRATEGY
 
The principal elements of the Company's business strategy include:
 
   
     Real Time, Reliable Worldwide Coverage.  The fully deployed ORBCOMM System
is designed to provide real time global data and messaging communications
services in a reliable and cost-effective manner. The ORBCOMM System's worldwide
coverage will enable it to provide tracking, monitoring and messaging services,
including Internet email capability, to customers that are currently beyond the
geographic reach of existing terrestrial wireline or wireless systems. The
ORBCOMM System is designed to deliver reliable communications services through
the use of acknowledgment and store-and-forward capabilities. ORBCOMM expects
that, with a planned constellation of 28 satellites, the ORBCOMM System will
provide communications availability generally exceeding 95% of each 24-hour
period in the United States and other temperate zones in the Northern and
Southern Hemispheres and exceeding 75% of each 24-hour period in the equatorial
region. On full deployment, the ORBCOMM System is designed to transmit a
U.S.-initiated
    
 
                                       45
<PAGE>   52
 
   
message ranging in length from six bytes to 100 bytes, depending on system
loading, in from approximately three to 25 seconds.
    
 
     First-to-Market.  The ORBCOMM System began providing commercial
intermittent service in February 1996. Prior to commencing commercial
operations, the space segment, network and management control systems, U.S.
Gateway and prototype Subscriber Communicators were tested extensively to ensure
technical viability. The Company believes that the existence of an in-service,
commercially operational system provides substantial "first-to-market" benefits,
including: (i) reducing technical risk; (ii) increasing the attractiveness of
the ORBCOMM System to potential Resellers, International Licensees and
Subscriber Communicator manufacturers; (iii) facilitating and encouraging the
development of software by Resellers and other application developers for a
variety of market applications because of the ability to test the hardware and
software in an actual operating environment; and (iv) developing a customer base
before other competing Little LEO systems are fully deployed, which the Company
believes will not occur before 2000. There can be no assurance, however, that
there will be no delays in the existing schedule associated with the
construction or deployment of the ORBCOMM System.
 
     Global Distribution of Services.  The Company believes the ORBCOMM System
can rapidly achieve a global presence in a cost-effective manner by capitalizing
on the significant resources of Resellers and International Licensees worldwide.
The Company plans to provide services in the United States through Resellers,
many of whom have an existing, well-established market presence through their
existing customer bases, market-specific brand name recognition and distribution
networks. Outside the United States, the Company will enter into Service License
Agreements with International Licensees who will be responsible in their
territory for, among other things, procuring and installing the necessary
Gateways, obtaining all regulatory approvals to provide services using the
ORBCOMM System and operating and marketing services using the ORBCOMM System.
The Company intends to select its International Licensees primarily by
evaluating the ability of the International Licensee to distribute and market
successfully the Company's services. Key components of such an evaluation
include the prospective International Licensee's: (i) reputation in the
marketplace; (ii) existing distribution capabilities and infrastructure; (iii)
financial condition and other resources; and (iv) ability to obtain the
requisite local regulatory approvals.
 
   
     Low-Cost Subscriber Communicators.  The Company is committed to promoting
the production of lightweight Subscriber Communicators that have a long battery
life and are widely available at prices attractive to a broad customer base. The
Company has provided extensive design specifications and technical and
engineering support to its various Subscriber Communicator manufacturers. The
Company currently has a development agreement with Panasonic and is in the
process of finalizing manufacturing and sales support agreements with Panasonic.
The Company has also executed Subscriber Communicator Manufacturing Agreements,
which include terms regarding the development, manufacture and sales support for
Subscriber Communicators, with Scientific-Atlanta, Magellan, Torrey Science and
Stellar. Panasonic has received authorization from the Company to manufacture
two basic Subscriber Communicators, one with and one without the ability to
receive positioning signals from the GPS system, both of which are now
commercially available. Torrey Science received authorization from the Company
in August 1996 and Stellar received authorization from the Company in September
1996 to manufacture a basic Subscriber Communicator. The Company expects that
both Torrey Science and Stellar will have units commercially available in the
first quarter of 1997. The Company believes that once its other Subscriber
Communicator manufacturers have units that are commercially available and once
the overall production volume for Subscriber Communicators increases, the price
for Subscriber Communicators will decline substantially. Panasonic and Stellar
have informed the Company that, in lots of at least several thousand, the price
for their respective Subscriber Communicators will be approximately $550 per
unit.
    
 
     Expertise of Strategic Partners.  Orbital and Teleglobe, the Company's
partners, have invested approximately $160 million in the ORBCOMM project. The
Company has used and will continue to use its partners' expertise and
capabilities to enhance the ORBCOMM System, including expertise in the design,
construction and deployment of satellites and the operation of international
wireline and wireless telecommunication services.

     Orbital, a Delaware corporation headquartered in Dulles, Virginia and with
offices in five countries is the founder of the ORBCOMM project, and through its
subsidiary, OCC, has a 50% Participation Percentage interest in ORBCOMM. Orbital
is a space technology and satellite services company, with annual revenues in
1995 of approximately $364 million, that designs, manufactures, operates and
markets a broad range of space products and services, including launch systems,
satellites, space sensors and electronics, ground systems and software products,
satellite access products and communications and information services. Under the
terms of the Procurement Agreement between Orbital and ORBCOMM, Orbital will,
among other things, construct 34 satellites (including eight ground spares),
launch 26 satellites and, on an optional basis, launch the eight ground spares.
The satellites and launch services are provided on a fixed-priced basis,
although the Procurement Agreement contains certain performance incentives with
respect to the satellites.
 
   
     Teleglobe, a Canadian corporation with 1995 revenues of approximately C$1.6
billion, provides international telecommunications services to over 240
countries worldwide through a network of submarine cables and satellite Earth
stations. Teleglobe currently has offices in ten countries. Teleglobe is owned
approximately 22% by BCE Inc., which is the largest public corporate entity in
Canada, and indirectly approximately 20% by Telesystem Ltd., a Canadian company,
which also has an interest in TIW. TIW has paging and cellular interests in
several countries around the world, including China, Mexico and India. Teleglobe
has substantial experience as an intercontinental provider of telecommunication
services and has played and continues to play an important advisory role in the
ORBCOMM project generally and in the Company's marketing and distribution
strategy in particular.
    
 
     Teleglobe has formed a partnership, Teleglobe Mobile, with TRI to hold its
interest in the ORBCOMM project. TRI operates the largest and one of the
fastest-growing cellular networks in Malaysia, with over 800,000 subscribers.
TRI also has cellular and paging joint ventures in five countries.
 
   
     The Company does not believe that its services will compete with the
existing cellular and paging operations of either TIW or TRI. The Company
expects that its services will complement the services currently provided by TIW
and TRI in the same manner that its services are intended to complement those
provided by other domestic cellular and paging service providers, primarily by
acting as a "gap-filler" that will expand the geographic reach of such services
and provide low-cost, seamless coverage. See "Business -- The ORBCOMM
System -- Future Applications."
    
 
CONSTELLATION DESIGN AND IMPLEMENTATION STRATEGIES
 
     The ORBCOMM System has been designed to provide for the delivery and
receipt of data communications and short, alphanumeric paging-like messages
anywhere in the world on a highly efficient and cost-effective basis. The
Company believes that multiple aspects of the ORBCOMM System design will result
in a low-cost product offering worldwide. The implementation plan for the
ORBCOMM System is intended to reduce the risk of cost overruns, system
performance shortfalls and system deployment delays. Important components of the
ORBCOMM System design and implementation strategies include:
 
   
     Low-Cost Satellite System.  The ORBCOMM System will consist of 28 LEO
satellites. Each satellite is designed specifically for the transmission of
short messages. This design focus eliminates a number of complex and expensive
components such as customized spot beams, on-board switching and high-powered
amplifiers that are required on larger, more complex satellites designed to
carry voice, video and data traffic. The less complex and more compact design of
the ORBCOMM System satellites (approximately 95 pounds) reduces the cost and
time of production and enables the Company to launch multiple satellites using a
single, relatively low-cost launch vehicle. The Company has sought to reduce the
risk of cost overruns by entering into the Procurement Agreement, a firm
fixed-price contract that covers the purchase of satellites, the provision of
launch services and the completion of the satellite control center. The
Procurement Agreement provides for the construction of 34 LEO satellites and the
launch of 26 LEO satellites for a total cost of approximately $163 million
(which amount excludes the cost of construction and launch of the Company's
first two satellites, which are already in operation). Because of the
architecture of the ORBCOMM System, the fixed costs to construct and deploy the
system are relatively low compared to the cost to construct and deploy a Big LEO
system. In addition, the marginal cost per message is very low as a result of
the design of the ORBCOMM
    
 
                                       47
<PAGE>   54
 
   
System. As a result, the Company believes that it will be able to offer low-cost
services to subscribers. See "Relationships Among the ORBCOMM
Parties -- Procurement Agreement."
    
 
     Communications Protocol Specifically Designed for Data and Messaging
Communications.  The ORBCOMM System uses a packet-switched communications
protocol. This design is well suited to ORBCOMM's goal of economic and efficient
delivery of short messages because it maximizes the amount of network capacity
available, while minimizing the overhead associated with sending each packet or
message, thereby lowering the per-message cost. The Company believes this design
will provide ORBCOMM with a substantial cost advantage versus the communications
protocols to be used by the proposed Big LEO systems such as Iridium and
Globalstar. Unlike the ORBCOMM System, Big LEO systems, which are designed
primarily for two-way voice traffic, are required to establish a
circuit-oriented connection over their network to transmit even short messages,
which significantly increases the per-message transmission cost for short
messages.
 
     Contractual and Other Means to Mitigate Delays and System Failures.  The
Company believes that the ORBCOMM System's design will reduce the Company's
exposure to cost overruns and delays associated with the production and
deployment of the ORBCOMM System due to launch or in-orbit satellite failure.
The principal elements that will contribute to this reduced exposure include:
(i) integration of existing technologies into the ORBCOMM System; (ii) use of
launch vehicles that will provide the Company with flexible launch schedules;
(iii) conduct of early development and prototyping; (iv) relatively simple,
lightweight design of the satellites, which will enable new satellites to be
ordered, constructed and launched in a shorter time frame than conventional LEO
and GEO satellites; and (v) procurement of nearly all components of the ORBCOMM
System (other than certain communications software) from a single contractor
(Orbital) that is responsible for end-to-end satellite performance and
integration. The redundant coverage provided by the ORBCOMM System also reduces
the ORBCOMM System's exposure to adverse events, which will enable ORBCOMM to
operate the ORBCOMM System with less than the full complement of satellites, if
necessary. See "Risk Factors -- Technological Risks; -- Limited
Insurance; -- Schedule Delays."
 
     In addition, the Company has adopted risk management policies designed to
reduce its exposure to cost overruns and to delays associated with deployment of
the ORBCOMM System, including: (i) establishment of fee holdbacks under the
Procurement Agreement to the extent that certain milestones identified in the
Procurement Agreement are not met by Orbital; and (ii) procurement of satellite
ground spares, which is expected to enable the Company to launch more quickly up
to eight satellites following an in-orbit or launch failure as soon as a launch
vehicle is available.
 
     Although the Company believes it has taken appropriate measures to mitigate
the risks associated with delays or cost overruns in connection with deployment
of the ORBCOMM System, there can be no assurance that such delays or cost
overruns will not occur. See "Risk Factors -- Limited Insurance; -- Schedule
Delays."
 
     Insurance Strategy.  The Company's insurance strategy implements a risk
management plan for the protection of the ORBCOMM System. First, to protect
against launch costs that may be incurred as a result of launch vehicle
failures, ORBCOMM intends to obtain launch insurance for each launch. This
insurance will provide ORBCOMM with the funds necessary to procure a replacement
launch vehicle in the event of a launch vehicle failure. Second, ORBCOMM will be
obligated to procure in-orbit satellite insurance against a satellite failure
after placement of such satellites into commercial service. Third, the
Procurement Agreement provides for the construction of eight spare satellites,
which represent self-insurance against the loss of up to eight satellites.
Therefore, until such time as the Company is required to use its ground spare
satellites, ORBCOMM does not intend to obtain insurance to cover the cost of
obtaining replacement satellites in the event of a launch vehicle failure or an
in-orbit failure prior to placement of such satellites into commercial service.
In the event that the Company is required to use its ground spare satellites,
ORBCOMM is obligated under the terms of the Indenture to procure insurance for
subsequent missions covering a loss of satellites as a result of a launch
vehicle failure or an in-orbit failure prior to placement of such satellites
into commercial service. In addition, in the event that: (i) the Company is
required to use its ground spare satellites as a result of an in-orbit failure
of satellites prior to placement of such satellites into commercial operation;
and (ii) there
 
                                       48
<PAGE>   55
 
are not sufficient insurance proceeds to cover the cost of a launch vehicle for
such ground spare satellites, the partners of the Company have agreed, under
certain circumstances, to contribute up to $15 million of equity or subordinated
debt financing to the Company, if needed, to fund the cost of such launch
vehicle. The Company does not have in-orbit insurance for the two satellites
currently operational and does not intend to procure launch or in-orbit
insurance for the two satellites to be launched as a secondary payload on a
Taurus launch vehicle.
 
   
     Early Demonstration of End-to-End Functionality.  ORBCOMM has made
significant progress in the development of the ORBCOMM System and currently
offers commercial intermittent service in the United States. After the launch of
the first two satellites, ORBCOMM successfully conducted "beta tests" of the
entire ORBCOMM System and United States ground network with selected major
customers in the second half of 1995, using prototype Subscriber Communicators
to demonstrate the ORBCOMM System's two-way global messaging and positioning
capabilities. ORBCOMM's operation of the two-satellite system during 1995
provided an opportunity to validate the performance of the end-to-end network.
Similarly, ORBCOMM demonstrated its ability to control the satellites and the
ground infrastructure, and to process messages using its computer network. As of
June 30, 1996, the ORBCOMM System had transmitted during testing and commercial
operations in excess of one million messages and had successfully completed
extensive internal and third-party testing, including a rigorous demonstration
program conducted by the DoD as part of JWID '95.
    
 
     The Company continues to experience, from time to time, certain technical
difficulties with its initial two satellites, including unplanned outages of
certain electronic systems and subsystems resulting in the temporary inability
to process subscriber communications. While the Company believes these technical
difficulties have been addressed as experienced, and that none of these
difficulties has resulted in a significant degradation of satellite performance,
there can be no assurance that performance degradation in these two satellites
will not occur in the future.
 
     The two ORBCOMM System satellites currently operational have provided the
Company with significant information regarding actual satellite performance in a
space environment. As a result of analyzing this information, as well as
information obtained prior to launch, ORBCOMM, in conjunction with Orbital, has
undertaken a redesign of certain system elements of the satellites.
 
     Use of Advantageous Radio Frequencies.  The ORBCOMM System has been granted
FCC approval to use radio frequencies in the 148.0-149.9 MHz band, and the
137.0-138.0 MHz and 400.075-400.125 MHz band for its uplink and downlink feeds,
respectively. The VHF frequencies are located just above those used for FM radio
broadcasts and just below those used for VHF marine push-to-talk radios. By
contrast, all of the Big LEOs are currently planned to be licensed in
frequencies above 1 GHz. The Company believes that the use of its allocated
frequencies will provide significant advantages for packet messaging and data
services compared to the use of frequencies above 1 GHz, including: (i) lower
power requirements to achieve acceptable link margins, which enhances battery
life and reduces ground and space segment costs due to the use of less complex
components; and (ii) better signal penetration, which decreases signal
degradation due to atmospheric interference such as rain and blockage by
foliage. The Company also believes that the substantial technical and
manufacturing base that already exists for a wide variety of communication
devices that operate near the frequency ranges used by the ORBCOMM System will
facilitate the development of low-cost Subscriber Communicators for the ORBCOMM
System.

     The ORBCOMM System is expected to be fully deployed with a 28 satellite
constellation in early 1998, although this estimate does not take account of
potential delays. The timeline below sets forth ORBCOMM's actual and planned
development milestones. See "Risk Factors -- Development Stage Company;

THE ORBCOMM SYSTEM
 
  SERVICES
 
     ORBCOMM System service offerings for mobile data and messaging
communications will fall into two broad categories with variations based on
market requirements: tracking and monitoring; and message and high-priority
communications.
 
     Tracking and Monitoring.  The Company believes that tracking and monitoring
users will include a broad group of industries that require a means of regularly
collecting data from, or in some cases controlling
 
                                       50
<PAGE>   57
 
equipment in, multiple remote locations. Major target markets include: (i)
worldwide mobile asset tracking; (ii) industrial monitoring and control
applications; and (iii) environmental data collection. Many of these users
manage numerous, widely dispersed sites in remote areas out of reach of the PSTN
or terrestrial-based wireless systems, and often accomplish data collection and
equipment control functions manually with on-site personnel. These methods can
be expensive, inaccurate or difficult to perform. The Company believes that
significant demand exists for a low-cost means of remotely performing these
tasks.
 
     Message and Priority Communications.  The Company believes that message
communications users will include a broad range of commercial and consumer users
who require a means of communicating with locations such as their office,
dispatch center or home or who require the ability to send priority messages or
positioning information. Examples include professionals who work away from their
office, fleet operators who require reliable messaging between a central office
and mobile assets, and individuals who desire a means of communicating short
messages or positioning information from an automobile, boat or other remote
locations. These users currently rely on pagers, cellular phones, fleet dispatch
systems and public pay phones, all of which can be unavailable, inconvenient or
expensive in certain geographic locations. In remote geographic regions outside
the United States, these PSTN and terrestrial-based wireless systems are not
always available or cost-effective. As a satellite-based system with coverage
available virtually anywhere on the Earth's surface, the Company can offer
messaging services through the ORBCOMM System.
 
   
  CURRENT ADDRESSABLE MARKETS
    
 
     The Company has identified a number of industries and industry segments in
the United States where there currently exists a demand for mobile data and
messaging communications services for tracking and monitoring, which the Company
views as the initial primary target applications for its services. These
existing tracking and monitoring applications include: (i) tracking and
monitoring of transportation assets and cargo; (ii) monitoring of assets in the
energy industry; (iii) environmental monitoring; and (iv) certain governmental
applications. The Company believes that certain portions of these industries or
industry segments possess characteristics or requirements that are particularly
well-suited to the services offered by Little LEO systems. The Company refers to
these portions as "addressable markets." The Company's description of potential
markets for its data and messaging communications service offerings and
estimates of the Company's addressable markets represent only the Company's
estimates as of the date hereof with respect to such markets. See "Risk
Factors -- Market Estimates."
 
     Transportation Assets and Cargo.  Transportation companies require a
cost-effective means of regularly and reliably monitoring the location and the
status of cargo globally to reduce cargo losses, improve service, and better use
transportation assets. Small ORBCOMM Subscriber Communicators could be installed
on trailers and programmed to monitor and transmit, on command or at regular
intervals, information regarding trailer status and location, and could be
specially designated for priority reporting and response. The transportation
assets and cargo market can be separated into four transportation categories:
trailers; long-haul trucking; containers; and rail cars.
 
     Based on industry data such as published in The Structure of the U.S.
Trucking Industry, The Outlook for Truck Trailers and 1994 Private Fleet
Directory, the Company believes the overall trailer segment, which includes full
truckload, less-than-full truckload and private trucking, aggregates
approximately 2.3 million trailers. The Company believes that the addressable
market for full truckloads comprises non-refrigerated trailers belonging to
large trucking fleets that need to improve trailer utilization. The addressable
market for less-than-full truckload comprises non-refrigerated trailers that
carry high-value goods and travel longer, less-than-full truckload routes
(greater than 400 miles) between regional centers. The addressable market for
private fleet trucks are those used in "just-in-time" manufacturing and
distribution systems and which, therefore, typically require high levels of
efficiency due to competition from for-hire companies. The Company expects the
addressable market for refrigerated trailers to comprise those trailers for
which cargo monitoring and trailer utilization are required. Trailers (both
refrigerated and non-refrigerated) are currently being tracked by geostationary
satellite-based systems (such as those offered by QUALCOMM and AMSC) that offer
seamless coverage, but depend on larger power sources that require the trailer
to be attached to the main engine of the tractor. As a result, when the trailer
is detached from the tractor, it can no longer be tracked. A low-power cellular
system (such as the system offered by Highwaymaster) can be used to track
untethered
 
                                       51
<PAGE>   58
 
trailers; however, the geographic coverage is limited and the Company believes
that the cost of cellular roaming may make this service cost-prohibitive.
Private trucking fleets typically use systems internal to their companies where
each trailer's number is manually recorded as trailers enter and leave a point
of distribution.
 
     Based on industry data published in 1994 Private Fleet Directory, Fleet
Owner Magazine and Report: Structure of the U.S. Trucking Industry, the Company
believes that the U.S. long-haul trucking industry comprises approximately
435,000 trucks. The Company's addressable market is characterized by smaller
fleets (typically less than 50 trucks) that need mobile communications to
compete with larger fleets but have been unable to afford the current service
offerings where equipment costs are approximately $4,000 per unit. A low-cost
alternative for these smaller fleets has been paging; however, paging currently
offers only a one-way short data link to the vehicle. The Company believes that
the addressable market for the owner-operated transportation vehicle sub-segment
comprises those vehicles contracted to larger, long-haul carriers. While these
larger carriers resist installing $4,000 mobile communications units on vehicles
they do not own, many are still requiring owner-operators to equip their
vehicles with mobile communications.
 
     Based on data contained in Intermodal Marine Container Report, the Company
estimates the industry segment representing containers (intermodal) that are
either refrigerated or designed to hold high-value, non-perishable cargo
comprises approximately 1.9 million containers. The Company expects that its
addressable market in this industry segment will comprise those containers
carrying the most valuable items subject to theft (e.g. electronics and
cigarettes). Currently, intermodal container transportation systems use manual
systems to record containers as they enter and leave yards. Unlike the ORBCOMM
System, these passive systems record where a trailer has been, but not where it
is, its status or the condition of its contents.
 
     Based on published data from Outlook for Freight Cars, the Company
estimates there are approximately 150,000 rail cars in the United States. The
Company believes that the addressable market for rail transportation comprises
those rail cars used to transport high-value cargo (e.g., automobiles,
refrigerated goods and paper rolls) or hazardous cargo comprising bulk
materials. The American Association of Railroads has mandated the use of
automatic equipment identifiers ("AEI") on rail cars. AEI systems consist of a
radio tag mounted on the rail car and a reader that records the identity of the
car as it passes by. AEIs therefore share the same limitations as bar code
systems because they only record where the trailer has been, not its current
location, status or the condition of its contents.
 
     Energy.  The Company believes that the ORBCOMM System can provide an
effective means of monitoring various assets used in the energy industry.
According to recent statistical abstracts of the United States, there are over
170,000 miles of oil pipelines and 250,000 miles of natural gas pipelines in the
United States, much of which is located in remote areas inaccessible to existing
communication networks. Pipeline operators take active measures to monitor lines
and limit pipeline corrosion to comply with laws by installing cathodic
protection systems that include a device called a rectifier. Protection systems
also are required by federal regulations on storage tanks, utility systems and
injection wells. The majority of protection system records are now compiled from
data collected by personnel who travel to the site and record the readings.
Conventional industry practice is to install one rectifier per mile of pipeline
with generally one transceiver (subscriber communication device) per rectifier.
However, several pipelines can be laid along one right-of-way, with a common
rectifier system, meaning that multiple rectifiers can feed into one transceiver
unit. The Company believes that the addressable market comprises the aggregate
number of rectifiers currently deployed on U.S. pipelines.
 
     The Company expects that another LEO satellite system can support the
collection of data from remote sites, with service and equipment costs
comparable to those of the ORBCOMM System; however, this system only supports
one-way service. Terrestrial wireless systems offer similar services at
comparable service costs to the ORBCOMM System, but geographic coverage is
limited. For very remote and hard-to-read meters, manual systems are typically
used, but they require that personnel travel to the site to read the meter on
the transceiver. The Company believes that pipeline operators would benefit
significantly from the ORBCOMM System. Subscriber Communicators powered by
batteries, solar cells or power sources already installed along the pipeline,
could be programmed to transmit required data at regular intervals to allow for
monitoring the
 
                                       52
<PAGE>   59
 
status of pipelines in remote locations. In addition to recording data,
Subscriber Communicators could be commanded to shut pipeline valves in the event
of a leak or other emergency.
 
     According to recent statistical abstracts of the United States, there are
approximately 853,000 wells producing natural gas and crude oil, and
approximately 164 million gas and electric utility meters in the United States.
The Company believes that its addressable market will be those production wells
and utility meters located in remote geographic locations. Private radio systems
based on VHF radio frequency, multiple-address radio and microwave are being
used to collect data in moderately remote areas. These systems have been
installed primarily for other communications purposes and so the incremental
cost of monitoring wells is low. However, private radio systems are not
cost-effective in locations where monitoring cannot be combined with other
communications functions.
 
   
     Environmental Monitoring.  Many industrial companies and government
agencies have a need to monitor meteorological, hydrological and environmental
data such as rainfall, water levels and water quality at remote sites. The U.S.
Environmental Protection Agency ("EPA") is responsible for establishing and
monitoring national air quality standards, water quality activities, solid and
hazardous waste disposal and control of toxic substances. The EPA has
established standards for air and water quality that require pollution abatement
procedures, which procedures rely heavily on the automated logging and
collection of data from remote sites. Based on discussions with existing
Resellers targeting the environmental monitoring market, the Company believes
that there are approximately 250,000 sites in the U.S. that require water
quality monitoring devices to measure bacteria, dissolved oxygen, phosphorus,
lead and cadmium. In addition to pollutants, water monitoring devices are used
to measure flow rate, temperature and water level. Based on discussions with
Resellers for the environmental monitoring market, the Company believes there
are approximately 125,000 sites dedicated to the collection of data on air
pollution, concentrations of carbon monoxide, ozone and sulfur dioxide, as well
as meteorological data on wind speed and barometric pressure. The Company
believes that the addressable market comprises those sites that are located in
highly remote areas not served by terrestrial systems, which can use Subscriber
Communicators to transmit small amounts of data relatively infrequently and on
an exception basis.
    
 
   
     The retrieval of data from remote environmental monitoring sites is
presently conducted using three methods: site visits; PSTN service; or
terrestrial wireless systems such as cellular telephone and specialized mobile
radio. The Company believes that ORBCOMM offers an attractive alternative to the
existing methods. Site visits are costly, time consuming and result in
significant data latency. Terrestrial wireline and wireless systems are limited
in coverage, particularly in remote areas where much of the environmental
monitoring takes place.
    
 
     Marine.  The Company has identified two marine industry segments, Fisheries
and Barges and Workboats, for which the total market is estimated at 246,000
vessels. Fisheries Product News and the National Fisheries Service count 200,000
fishing vessels in the U.S. commercial fleet. The Company's addressable market
is expected to be those fishing vessels that operate primarily in the Gulf of
Alaska, the Northwest United States and the Northwestern Atlantic. These vessels
usually remain at sea for extended periods and operate on extremely tight
margins with operating costs that are carefully controlled. As a result, they
need low-cost communications systems to meet safety and regulatory requirements
and to exchange commercial and operational information with their offices, fuel
providers, provisioners and packing houses.
 
     The American Waterways Council estimates that there are 46,000 barges and
workboats that operate in U.S. rivers and on coastal waters. The Company expects
that its addressable market will comprise barges that operate without
independent sources of power and carry grain, coal and other commodities. They
traverse U.S. waterways in groups of barges that are "fleeted" together and
pushed by towboats and require energy-efficient monitoring and communications
devices to transmit position reports, cargo status reports and security
information. Tugs, towboats and supply/service boats also need low-cost two-way
communications to send operational and service-related data to their land-based
headquarters and receive dispatch instructions in return.
 
     For long-haul communications, commercial fishing vessels use either HF
radio or one of the Inmarsat services. HF radio is considered unreliable, not
cost-effective and difficult to use, while Inmarsat requires a
 
                                       53
<PAGE>   60
 
considerable upfront investment of capital. The Company expects that some
commercial fishing vessels may acquire service from AMSC. Currently, there is no
technology that provides for the tracking of barges. Since barges have no
independent power source, only a system that is both ubiquitous and energy
efficient is feasible. Most barge tracking is presently conducted using paper
records that are usually several days old. Workboats frequently use cellular
telephones, particularly in the Gulf of Mexico. Given the high cost of cellular
roaming and the potential for unauthorized use, the ORBCOMM System may provide a
more efficient, cost-effective tracking service.
 
     U.S. Government Applications.  The Company believes U.S. Government
applications represent a major target market for its services. Pressures to
contain Federal spending and specific acts of Congress have resulted in a major
change in the procurement practices in the DoD and civil agencies, causing them,
where possible, to purchase satellite-based services from commercial providers.
The Company believes that use of LEO systems like the ORBCOMM System will
provide Government users with low-cost solutions, low probability of intercept
and detection, and worldwide availability. The Company expects to compete to
provide LEO service to the U.S. Government, including in connection with certain
programs already announced by the U.S. Government.
 
     The DoD is developing the Global Transportation Network ("GTN") to track
personnel, aircraft and weapon systems anywhere in the world. Effective military
logistics requires location identification and the ability to communicate
tasking instructions. Control is required at all locations from rear depots to
front-line combat elements, with integrated communications providing the
essential link. The GTN is a $230 million program with an annual operating
budget of $45 to $50 million. GTN is being developed because no global system
currently exists to satisfy the requirements for monitoring status. Lacking a
technology that provides cost-effective tracking and monitoring on a global
basis, the U.S. military has been relying on manual record keeping, which has
recently been supplemented by distributed database systems communicating over
DoD-owned and/or leased lines. Asset tracking is currently performed at the
endpoints of the distribution chain. For this reason, a misdirected shipment can
only be relocated by tracing forward from its most recent known location, and
this can take weeks to accomplish. The Company believes the ORBCOMM System will
provide data on demand or on a scheduled basis for use by the government.
 
     The Defense Messaging System ("DMS") is a $1.5 billion project with an
annual operating budget of $45 million to provide messaging for the DoD, NATO
and certain civilian agencies. The Company believes that Little LEO systems
would complement existing and planned terrestrial wireless and wireline services
by providing service in geographic locations where such services are not
available or are not cost-effective. Today, numerous independent email systems
provide messaging throughout the military, with Autodin currently processing 35
million messages per month. Autodin messages are sent between fixed terminals in
locations throughout the world. The Company believes that in the DMS
implementation, the ORBCOMM System could offer users the ability to send and
receive messages regardless of their physical location.
 
     The Company believes that there are additional DoD programs that may use
the services of Little LEO systems including the Global Command and Control
System, budgeted for $500 million; the Air Mobility Command and Control
Information Processing System, budgeted for $210 million; the Combat Search and
Rescue program to locate downed pilots, budgeted for $220 million; the Mobile
Satellite Service program, budgeted for $87 million; the Joint Surveillance
System budgeted for $85 million; and the Commercial Satellite Communications
Initiative, budgeted for $1.6 billion.
 
     There are also a number of civil government applications suitable for
Little LEO systems. The Post-FTS 2000 is a program to provide long distance
domestic and international wireless Internet access, data and email to U.S.
government civilian agencies. It is a ten-year contract providing an estimated
$300 to $400 million in revenues to service providers. The U.S. Departments of
State, Justice and Transportation are also developing wireless email and
messaging programs. The existing FTS2000 provides domestic long distance calling
service to the federal government only. The new contract for service includes
wireless, mobile and international services.
 
     The Company believes that these new programs have requirements currently
unfulfilled by existing systems. Each program promotes the vision of extending
communications down to individual soldiers and
 
                                       54

system operators. Currently, there is no dedicated DoD system available using
inexpensive, small, lightweight user terminals. The Company believes that Little
LEO systems like the ORBCOMM System can provide such service on a global basis.
 
     Foreign Government Applications.  Use of Little LEO systems such as the
ORBCOMM System is expected to provide foreign governments with low-cost
applications, low probability of intercept and detection and worldwide
availability. Potential defense applications include transmission of
GPS-determined position data for maneuvering units and downed pilots and
transmission of air defense, fire support data, asset tracking and tactical
messaging. Potential civil government applications include wide-area clandestine
communications, monitoring and control of natural resources and search and
rescue functions. For foreign governments, the Company anticipates that the
ORBCOMM System could improve coverage and reliability and reduce the cost of
such applications.
 
   
     With respect to the provision by the Company of services using the ORBCOMM
System on an international basis, the Company believes that certain of its
international business activities, including its provision of services through
International Licensees to foreign end-users, public or private, will be
governed primarily by the internal laws of the relevant foreign countries or
regions and will not be governed by U.S. law.
    
 
  FUTURE APPLICATIONS
 
     In addition to the markets and applications (such as those described above)
that have already displayed a demand for mobile data and messaging
communications services, the Company believes that with the full deployment of
the constellation, the ORBCOMM System's combination of capabilities will
stimulate new demand, especially among potential messaging users. The explosive
growth of communication services is being fueled in part by the need for both
consumer and business users to improve their productivity by being in constant
contact with information sources. The growth is particularly evident in the
wireless segment of the industry. Terrestrial cellular systems only began
operation in the United States in 1982 and by the end of 1995 there were more
than 33 million subscribers in the United States. According to Malarkey-Taylor
Associates, Inc./Economic and Management Consultants International, Inc., there
will be approximately 334 million cellular/PCS subscribers globally by 2001. The
paging industry, which began in the 1950s, also continues to grow at least 20%
per annum and currently there are more than 34 million one-way paging
subscribers in the United States alone. Additionally, the Internet is growing at
20% per month and there are expected to be over 300 million Internet users by
2000. This need is also being fueled by an increasingly mobile society that
desires to be reachable anywhere, anytime and the growth of a global
marketplace.
 
     The Company expects that in the United States, the ORBCOMM System will
complement existing and planned terrestrial wireless communications systems, by
providing coverage in geographic areas where such services are not offered or by
enhancing data applications currently being provided through the PSTN or the
PSDN. Internationally, the Company believes that the ORBCOMM System can offer
services in developing countries or remote regions where basic telephone service
or data and messaging services are not available. As a satellite-based system
with coverage of virtually all of the Earth's surface, the Company can
efficiently and cost-effectively offer communications services in these
geographic areas through the ORBCOMM System.
 
     The ORBCOMM System's combination of low-cost Subscriber Communicators and
seamless coverage is expected to provide a range of new personally portable
services and gap-filler capabilities such as: (i) stand-alone messaging; and
(ii) hybrid messaging.
 
     Stand-Alone Messaging.  In certain communications applications, the major
requirements are low-cost handsets and ubiquitous coverage. The handsets must
also be easy to use, provide long battery life, and be readily carried in a
purse, briefcase or suit pocket. Typically, use will be infrequent and the
length of the message short. Potential user requirements include: (i) persons
who want the standby ability to notify someone at the office or at home; and
(ii) pleasure boaters, other recreational users, and motorists who may find the
system useful for priority communications and for convenience.
 
     Based on data published by the National Marine Manufacturers Association,
the Company believes that approximately 77 million Americans participate in
boating activities and that its addressable market comprises
 
                                       55
<PAGE>   62
 
those owners who enjoy traveling a considerable distance outside the range of
terrestrial communications systems. Their boats are generally designed to
provide overnight accommodations for extended periods and are usually 26 feet or
longer. There are approximately two million households with powerboats and
900,000 with sailboats in this size category. The primary market requirements
are concern with safety and the availability of a low-cost, lightweight,
personally portable unit.
 
     Recreational boaters typically use VHF radio and/or cellular telephone
where tower-based systems are available. Some individuals rely on HF radio and a
very small number employ Inmarsat services. Due to the significant geographic
coverage and expense limitations of these alternatives, however, there are few
viable communications alternatives available to outdoorsmen.
 
   
     Based on market research conducted on behalf of the Company, the Company
estimates there are approximately 22 million American households whose members
frequently engage in one or more of the following "back-country" activities:
hunting; hiking; overnight camping; and backpacking. The Company believes that a
portion of these households form an addressable market for the ORBCOMM System
due to the frequency of their activities and the likelihood that they will
travel outside the range of terrestrial communications.
    
 
     Hybrid Messaging.  The advent of corporate email systems and small,
lightweight personal computers is creating a large body of users who want the
convenience and flexibility to communicate information without being bound by
wireline or the limits of wireless systems. The ORBCOMM System, due to its
low-cost Subscriber Communicators and global availability, could serve as a
gap-filler for end-users, and appeal to terrestrial wireless system operators
currently offering such services in metropolitan areas. The ORBCOMM System could
provide extended coverage with minimal investment in new infrastructure and
could expand vertical market opportunities for terrestrial operators.
 
     A recent industry report indicated that the volume of messages carried over
the Internet is currently 300 billion per year, of which 70% are messages of
1,000 characters or less. It is estimated that 40% of U.S. territory will remain
uncovered by terrestrial communications due to sparse population density. The
Company therefore believes there is a potential niche market for email and
personal messaging in addition to messaging used primarily for business or
industrial reasons. The Company believes that companies that currently provide
terrestrial wireless communications services may use the ORBCOMM System as a
service area gap-filler and extend their networks to remote areas.
 
  MARKETING
 
     Domestic.  The exclusive right to market the ORBCOMM System in the United
States is held by ORBCOMM USA. See "Relationships Among the ORBCOMM Parties."
ORBCOMM USA has developed a comprehensive marketing plan that includes
distribution, applications development, customer service and pricing strategies.
The Company's overall goal is to penetrate rapidly specifically targeted markets
to promote efficient use of system capacity. Currently, while offering
commercial intermittent service, ORBCOMM USA is seeking to build an initial base
of subscribers in the United States, and expand on its agreements with key
channels of distribution. During the fully operational stage, the Company
expects that ORBCOMM USA's sales and marketing staff will primarily support
indirect channels of distribution.
 
     ORBCOMM USA is in the process of negotiating and signing agreements with
Resellers who purchase ORBCOMM System services directly from the Company and
resell these services to end-users in a specific industry and/or market as part
of a package that may include other products or services. ORBCOMM USA's
relationship with a Reseller is governed by a reseller agreement that details
each party's rights and responsibilities with respect to developing and
maintaining customer relationships, as well as the cost of service to the
Reseller. In soliciting customers, the Reseller "adds value" to the basic
service offering by bundling related applications software, hardware or product
packaging for its respective industry or market segment. Existing mobile data
carriers are expected to offer ORBCOMM System services by taking advantage of
the ORBCOMM System's "gap-filler" properties as well as its geolocation and
acknowledgment features. Such additional ORBCOMM partners are likely to come
from such areas as paging, PCS, mobile data, cellular, and intelligent
transportation systems.
 
                                       56
<PAGE>   63
 
     In the United States, service pricing is based on many variables, including
the availability and cost of substitute services, the cost of providing service
and the nature of the user application. Pricing generally incorporates an
initial registration charge, a recurring monthly charge for access to the
ORBCOMM System and usage charges based on end-user activity. In charging for
usage, the Company has developed a pricing structure in the United States that
suits the usage patterns for the initial vertical markets addressed by the
existing two satellite system. Prices for priority and other real time messaging
will be developed as the full deployment of satellites in the ORBCOMM System
occurs. It is likely that multiple pricing alternatives will be offered in the
United States including peak/off-peak, volume discounts, and annual contract
commitment options.
 
   
     To date, ORBCOMM USA has signed 25 reseller agreements with the following
companies:

     International.  The Company holds the exclusive right to market the ORBCOMM
System outside the United States, and has licensed this right to ORBCOMM
International. See "Relationships Among the ORBCOMM Parties." Provision of
communication services using the ORBCOMM System outside the United States is
expected to be achieved through International Licensees authorized by ORBCOMM

International. ORBCOMM International is in the process of negotiating and
signing agreements with International Licensees within various countries or
regions of planned service outside of the United States.
 
     The Company has a standard Service License Agreement for International
Licensees, although there may be variations in the terms of specific agreements.
The Service License Agreement authorizes, among other things, the exclusive
access by the International Licensee to the ORBCOMM System satellites in a
designated geographic area and permits the limited use of certain ORBCOMM
proprietary technologies and intellectual property. While the Agreement contains
specific obligations on both parties, it also contains express provisions that
are intended to disclaim all system performance warranties and includes broad
limitation of liability clauses. The Agreement will have a ten-year term,
although it may be terminated earlier under certain conditions including in the
event of a default.
 
     International Licensees will be responsible for obtaining all necessary
licenses and approvals for the use of the ORBCOMM System and the construction
and operation of the Gateways in the designated territories. Accordingly, in
selecting authorized International Licensees for a particular country, ORBCOMM
International considers such factors as an International Licensee's: (i)
reputation in the marketplace; (ii) existing distribution capabilities and
infrastructure; (iii) financial condition and other resources; and (iv) ability
to obtain the requisite local regulatory approvals. International Licensees will
pay fees for access to the ORBCOMM System in their territory, including a
monthly Satellite Usage Fee. The Satellite Usage Fee is calculated as the
greater of a percentage of gross operating revenues and a data throughput fee,
which percentage and dollar amount may be increased by the Company in accordance
with the terms of the Agreement.
 
   
     In conjunction with the execution of a Service License Agreement, an
International Licensee will be required to purchase from ORBCOMM an ORBCOMM
Gateway, which will include a specific number of Earth stations. In certain
defined circumstances, an International Licensee may be permitted by the Company
to share a Gateway with another International Licensee in an adjacent territory,
thereby reducing the initial out-of-pocket start-up costs for an ORBCOMM System
franchise. For example, ORBCOMM has executed a Ground Segment Facilities Use
Agreement with ORBCOMM Canada, pursuant to which ORBCOMM Canada is authorized
for a fee to access and use the U.S. Gateway on a shared basis with ORBCOMM USA.
    
 
     Retail pricing in international markets will be at the discretion of the
International Licensees, and is expected to vary from country to country to
reflect variations in economic conditions, the availability of substitute
services, local customs, and government policy as required to be competitive
with other services.
 
   
     As of September 30, 1996, ORBCOMM International has signed ten Memoranda of
Understanding with potential International Licensees and is in active
negotiations with nine other potential International Licensees; taken together,
these 19 potential International Licensees represent approximately 35 countries
around the world. The Company intends to convert substantially all its existing
Memoranda of Understanding into Service License Agreements during the next three
to 18 months, although there can be no assurance the Company will be successful
in each case. In addition, ORBCOMM International has signed Service License
Agreements with three International Licensees. On October 15, 1996, ORBCOMM
signed a Service License Agreement with ORBCOMM Europe, a consortium of European
companies, which has been given the exclusive right to market services using the
ORBCOMM System to approximately 40 European countries. ORBCOMM has also executed
a Service License Agreement with ORBCOMM Canada, which is controlled by
Teleglobe and which has been given the exclusive right to market services using
the ORBCOMM System in Canada. The third Service License Agreement was signed
with Celcom, a wholly owned subsidiary of TRI, and grants Celcom the exclusive
right to market services in Malaysia, Singapore and Brunei.
    
 
  SYSTEM ARCHITECTURE
 
     The ORBCOMM System consists of four operational segments: (i) a space
segment consisting of a constellation of 28 LEO satellites; (ii) a ground
segment consisting of Gateways, the major elements of which include Earth
stations sending and receiving signals and a message switching system that
processes the message traffic; (iii) a control segment to monitor and manage the
flow of information through the system;
 
                                       58
<PAGE>   65
 
and (iv) a subscriber segment consisting of communicators used by subscribers to
transmit and receive messages to and from nearby satellites.
 
     Overview.  To use the ORBCOMM System, a user creates a text message using a
computer or Subscriber Communicator device, which message is sent to the nearest
ORBCOMM System satellite and delivered to an ORBCOMM Earth station, which
supports communication with the satellites, and then to the Gateway Switching
System, which processes the messages. Within the Gateway, the message is
processed using a combination of ORBCOMM-developed and commercial email
software, and sent on to its ultimate destination. If desired, an
acknowledgement message is returned to the sender. The final delivery may be to
another Subscriber Communicator, or may make use of public/private X.25 data
networks, the Internet, or even text-to-fax conversion.
 
     To control costs and design and implementation risks, the ORBCOMM System
architecture, where possible, makes use of existing, mature technologies and
conforms to internationally accepted standards. The ORBCOMM System network
architecture comprises a multi-nodal packet network using X.400 messaging and
Time Division Multiple Access (TDMA) as the enabling technologies.
 
     As shown below, the ORBCOMM System is divided into four operational
segments: the space segment; the ground segment; the control segment; and the
subscriber segment.
 
                     [GRAPHIC MATERIAL HAS BEEN DELETED]
 
     Space Segment.  The Space Segment will consist of a constellation of 28
satellites comprising three planes of eight satellites and two planes of two
satellites in highly inclined orbits (of which one plane of two satellites has
been launched), all at approximately 775 kilometers above the Earth. The two
in-orbit satellites are in a 70(++) inclined plane at an altitude of
approximately 740 kilometers. Weighing approximately 95 pounds, the MicroStar
satellites are produced by Orbital and generally will be deployed in groups of
eight using Orbital's Pegasus XL launch vehicle. Two satellites are to be placed
in a high-inclination orbit using an Orbital Taurus launch vehicle. The design
of the remaining 26 satellites (as well as the eight ground spares) is expected
to be identical.
 
     The satellites, each of which is a self-contained node of the ORBCOMM
System, are equipped with a VHF communications infrastructure capable of
operation in the 137.0-150.05 MHz and the 400.075-400.125 MHz bands. The use of
the spectrum is managed by an on-board computer that employs an
ORBCOMM-developed Dynamic Channel Activity Assignment System ("DCAAS"). The
DCAAS contin-
 
                                       59
<PAGE>   66
 
uously scans the authorized spectrum, identifies frequencies in use and assigns
channels to minimize the possibility of interference. DCAAS is expected to
change the frequency of the uplink random access channels every five to 15
seconds. The ORBCOMM System satellites can also transmit a UHF beacon that
provides Subscriber Communicator manufacturers with the ability to supply
enhanced, low-cost, Doppler positioning.
 
     Under the terms of the Procurement Agreement, the Company is purchasing an
additional eight satellites that may be used as ground spares and launched in
the event of the loss of satellites as a result of a launch failure or in-orbit
satellite failure. In the event such satellites are not needed for such purpose,
ORBCOMM currently intends to launch these satellites as an additional plane of
eight, as authorized by the FCC License. This would increase global coverage and
provide additional system redundancy. In addition, the Company has an option to
procure a second generation satellite system that would replace the system it is
now deploying at the end of the system's expected life. The option, currently
priced at $166.1 million (subject to adjustment for inflation and excluding
taxes, if any, and the cost of launch and satellite insurance) can be exercised
by the Company at any time.
 
     The Procurement Agreement requires Orbital to demonstrate compliance with
the detailed technical satellite performance requirements defined in the ORBCOMM
System Specifications, which specifications describe the end-to-end satellite
performance. Except for the communication software, which is the responsibility
of ORBCOMM, Orbital is responsible for the performance of the satellites, the
U.S. Earth stations and the satellite management functionality of the Network
Operations Center ("NOC"). Orbital must comply with a verification and test
plan, which defines the detailed verification tests and acceptance criteria for
each of the ORBCOMM System elements.
 
   
     The Procurement Agreement with Orbital provides for the launch of 24
satellites on the Pegasus XL. Orbital's Pegasus XL vehicle is launched from
beneath Orbital's leased, modified Lockheed L-1011 and is capable of deploying
satellites weighing up to 1,000 pounds into low-Earth orbit. Through June 30,
1996, Orbital has conducted a total of eight standard Pegasus missions, all of
which were fully or partially successful. Whether a mission is fully or
partially successful depends on the particular mission requirements designated
by the customer. In the two partially successful missions, the satellites
achieved useful orbits and were able to be operated by the customer and
performed at least part of their intended missions. Prior to its successful
flights in March, July and August 1996, the modified Pegasus XL, an enhanced
version of the standard Pegasus, had two unsuccessful flights, one occurring in
June 1994 and the other in June 1995. The first Pegasus XL failure was caused by
inaccurate aerodynamic modeling of the vehicle. The second Pegasus XL failure
resulted from human assembly error involving the improper installation of a
small component that prevented the Stage 1/Stage 2 interstage from properly
separating from Stage 2. After the Pegasus XL failure in June 1995, Orbital led
a comprehensive internal review and commissioned an independent assessment of
the Pegasus XL's design, manufacturing and assembly methods and launch
procedures. Orbital also conducted extensive engineering analyses and subsystem
testing to characterize flight margins and to implement appropriate design
changes. All analyses and tests were conducted with broad customer input from
NASA, the U.S. Air Force, the Ballistic Missile Defense Organization and the
Aerospace Corporation. These reviews, carried out by members of the aerospace
industry and government experts, recommended 88 engineering and procedural
changes to enhance product robustness, all of which were implemented by Orbital.
Pegasus XL returned to flight on March 8, 1996, successfully launching a
satellite for the U.S. Air Force to its intended orbit and had successful
flights in July and August 1996, in each case delivering a NASA satellite to its
designated orbit.
    
 
     In addition, the Company expects to launch two additional satellites as a
secondary payload on Orbital's Taurus launch vehicle. Taurus is a four-stage,
ground-launched derivative of Pegasus that can carry up to 3,000 pounds to
low-Earth orbit. In March 1994, Orbital successfully launched the first Taurus
vehicle, deploying two satellites for the Defense Advanced Research Projects
Agency into their target orbits.
 
     The ORBCOMM network is unique in that both the Ground Segment and the
Subscriber Segment (described below) communicate with the satellite in the same
band, thus eliminating the design complexity, as well as the associated mass,
power and cost, of supporting multiple radio payloads on a single satellite. The
satellite also contains an intelligent packet-routing capability, including a
limited store-and-forward capability.

     Ground Segment.  The Ground Segment consists of Gateways strategically
located throughout the world. The role of the Gateway is to provide access to
the Space Segment and interface to public and private data networks. The major
elements of a Gateway include:
 
     - Earth stations, each of which is composed of two radomes, with enclosed
       VHF tracking antennae, one of which is redundant, associated pedestal,
       controller, and radio equipment;
 
     - Gateway Message Switching System, which processes the message traffic and
       provides the interconnection to the terrestrial networks; and
 
     - Gateway Management System, which manages the Gateway elements.
 
     To provide services using the ORBCOMM System in a particular geographic
region, an appropriately located Gateway is required. Substantially all elements
of the U.S. Gateway have been constructed, including four Earth stations located
in New York, Arizona, Georgia and Washington. ORBCOMM expects to enter into
agreements with International Licensees for the construction of Gateways outside
the United States. The cost and implementation of these Gateways is expected to
be borne by the International Licensees.
 
     Each Earth station comprises two radomes set on top of a sandwich-walled
cinderblock support structure. The radome, which weighs approximately 3,300
pounds, is approximately 28 feet in diameter. The total height of the structure,
measured from the top of the radome to the foot of the base, is approximately 33
feet. Each Earth station is unmanned, and contains a freestanding shelter and an
optional fuel tank and power generator. The Gateway satellite links have been
designed to make use of single uplink and downlink channels for all ORBCOMM
System satellites by using a TDMA protocol. This protocol will permit several
Gateways to communicate simultaneously with a single satellite. The TDMA
protocol has several advantages, including the ability to provide a virtually
seamless handover of a satellite from Earth station to Earth station under the
centralized control of the NOC.
 
     Control Segment.  The Control Segment monitors and manages all network
elements to ensure continuous, consistent operations in the provision of quality
service. The Control Segment is housed at the NOC, with a back-up NOC planned to
be constructed in the third quarter of 1997.
 
     The Control Segment systems include a network management system that
presents the status of all network elements and a space vehicle management
system. Through the U.S. Gateway, managed from the NOC, ORBCOMM has access to
the Space Segment for command and control purposes, although, consistent with
the rules and regulations of the FCC, OCC maintains ultimate control over the
ORBCOMM System.
 
     Subscriber Segment.  The Subscriber Segment consists of various models of
Subscriber Communicators that are generally designed to support specific
application needs of users. The Subscriber Communicator models will include: (i)
vehicular-powered Subscriber Communicators that could be used in asset tracking,
cargo monitoring, or vehicular operation monitoring; (ii) externally powered
Subscriber Communicators for fixed applications such as pipeline monitoring,
remote device control, or environmental monitoring; and (iii) self-contained,
battery- and/or solar-powered Subscriber Communicators that would support
applications where commercial or other external power is not available,
including personal messaging applications.
 
     Subscriber Communicators targeted for industrial or telemetric applications
are designed to interface with sensors or control devices through an
industry-standard serial interface using a proprietary communications protocol,
developed to take advantage of the packet nature of the ORBCOMM System.
Subscriber Communicators targeted for personal use will incorporate interfaces
such as integrated keyboards or touch-sensitive screens. Additionally, while the
ORBCOMM System satellites are designed to support Doppler position determination
in the Subscriber Communicators, certain Subscriber Communicator models will
also be equipped with GPS receivers, permitting more rapid and more accurate
location determination.
 
   
     To ensure the availability of Subscriber Communicators having different
functional capabilities in sufficient quantities to meet demand, the Company has
provided extensive design specifications and technical and engineering support
to various Subscriber Communicator manufacturers. The Company currently has a
development and initial supply agreement with Panasonic, which has received
authorization from the Company for a basic Subscriber Communicator and has units
that are now commercially available. The Company is in the process of finalizing
a manufacturing and a sales support agreement with Panasonic. The Company has
also executed Subscriber Communicator Manufacturing Agreements, which include
terms
    
 
                                       61
<PAGE>   68
 
   
regarding the development, manufacture and sales support for Subscriber
Communicators, with Scientific-Atlanta, Magellan, Torrey Science and Stellar.
Both Torrey Science and Stellar have received authorization from the Company to
manufacture a basic Subscriber Communicator and the Company expects that both
companies will have units commercially available by the first quarter 1997.
Panasonic and Stellar have informed the Company that, in lots of at least
several thousand, the price for their respective Subscriber Communicators will
be approximately $550 per unit.
    
 
COMPETITION
 
     Competition in the communications industry is intense, fueled by rapid and
continuous technological advances and alliances between industry participants
seeking to use such advances on an international scale to capture significant
market share. At this time, the ORBCOMM System is the only commercial Little LEO
system to be licensed fully for all segments of its system within the United
States. ORBCOMM inaugurated commercial service on February 1, 1996, becoming the
first commercial Little LEO mobile satellite service provider. The Company
believes that commencement of commercial service provides it with a substantial
head start in developing markets, distribution systems, applications and
customers globally. The Company expects that potential competitors will include
other Little LEO systems, such as Starsys, and Big LEO systems, such as the
Iridium and Globalstar systems.
 
     Starsys is licensed to construct and operate a multiple-satellite
constellation that, if deployed, could compete directly with the ORBCOMM System.
Starsys employs code division multiple access ("CDMA") modulation (spread
spectrum) that must operate in spectrum that is allocated on both a "primary"
and "secondary" basis to Little LEO services. As a result, Starsys will operate
at low power levels to avoid interference to other services. The low power
levels result in a maximum transmission rate of 600 bps from Subscriber
Communicators compared with 2,400 bps for the ORBCOMM System. In addition, the
U.S. Government has imposed a channel occupancy limit on Starsys of 25% of that
permitted for the ORBCOMM System to prevent interference to existing U.S.
Government systems. The Company believes that no operational Starsys satellites
will be launched until 1997 at the earliest, and that completion of the network
will not be accomplished before 2000.
 
     One other entity has been licensed by the FCC in the first processing round
to provide Little LEO satellite services in the United States. Volunteers in
Technical Assistance ("VITA"), a not-for-profit organization, has been licensed
for one of the two satellites for which it applied. VITA will use a small amount
of uplink and downlink spectrum to transmit health, research and scientific data
on a delayed basis between developing countries and the United States. VITA's
first satellite was destroyed in 1995 as a result of a launch vehicle failure.
VITA has requested that the FCC authorize it to launch a replacement satellite.
It is expected that the FCC will authorize VITA to launch a replacement
satellite and will grant VITA's second satellite application in its second
processing round for Little LEO applications. See "Regulation -- United States
FCC Regulation."
 
     The Company does not expect that any of the other proposed Little LEO
systems currently participating in the second licensing round before the FCC
will be in a position to offer competing data and messaging communications
services before the year 2000. Even if the FCC were to license one or more of
these other applicants in the near future, the Company holds a substantial
advantage over these potential competitors by virtue of its having already
obtained FCC licensing for all elements of its system in the United States, by
achieving, in large part, international coordination of its designated
frequencies through the ITU, and having already designed, constructed and
deployed a fully functional, end-to-end system. Over the course of the next
several years, the Company is expected to obtain further advantages over these
potential competitors by launching the remaining satellites in the ORBCOMM
System, by signing agreements with additional Subscriber Communicator
manufacturers, by signing reseller and Service License Agreements with
additional marketing entities and by expanding its marketing activities
generally as the ORBCOMM System matures.
 
     Plans for Little LEO systems have been announced in Russia, France, Tonga,
Brazil, Uganda, Australia and Korea. However, with the sole exception of the
French candidate system, the ORBCOMM System and those of the other United States
first round licensees are expected to occupy all but a small portion of the
currently allocated spectrum and are protected from harmful interference from
all other systems.

<PAGE>   69
 
     The Big LEO systems, which will operate LEO mobile satellite systems using
radio frequencies above 1 GHz, are not expected to be ready for real time,
uninterrupted service before 1998. In addition, all the Big LEO systems are
designed primarily to provide two-way voice services which require larger, more
complex satellites than the ORBCOMM System satellites, and larger constellations
to provide coverage. As a result, the cost of the Big LEO systems is
significantly greater than those of the ORBCOMM System. Based on filings with
the FCC, Iridium anticipates an initial service date in 1998 for a proposed
66-satellite constellation to provide voice and other communications services at
usage charges of approximately $3.00 per minute plus tail charges (land-line
extension charges). The total system cost is expected to be approximately $4.7
billion. The Globalstar system is expected to cost approximately $2 billion and
consists of a constellation of 48 satellites with usage charges of approximately
$0.55 per minute. The initial service date for the Globalstar system is
anticipated to be in 1998. Another satellite system designed to provide
primarily voice communications is the Odyssey system, a project in which
Teleglobe has an interest. Odyssey is a medium-Earth orbit system, which will be
composed of 12 satellites operating at an altitude of 10,355 kilometers above
the Earth. Odyssey proposes to begin operations and to become fully operational
by 2001. The total system cost is expected to be approximately $2.5 billion.
 
     Satellite-based communications systems are characterized by high up-front
costs and relatively low marginal costs of providing service. A number of Big
LEO and Little LEO systems are presently being proposed, and while the
proponents of these systems foresee substantial demand for the services they
will provide, the actual level of demand will not become known until such
systems are constructed, launched and begin operations. In addition, the ORBCOMM
System will compete with several existing and planned GEO systems such as the
AMSC system. Big LEO and GEO systems are designed primarily to provide two-way
voice services, which require larger, more complex satellites and require a
circuit-oriented connection over their network to transmit even short messages,
which significantly increases their per-message cost for such short messages.
However, these systems could seek to offer services similar to those offered by
the ORBCOMM System. In such case, price competition could be intense.
 
     The ORBCOMM System is not intended to compete with existing and planned
terrestrial messaging and data systems. Rather, the Company believes that the
ORBCOMM System will complement these systems, which provide low-cost services
primarily in metropolitan areas where subscriber densities justify construction
of radio towers. Such systems generally do not have sufficient coverage outside
metropolitan areas, making them less attractive to vertical markets such as
field service operations and trucking, where assets spend large portions of
their operating time outside terrestrial system coverage areas. The ORBCOMM
System presents an attractive complement to tower-based services because it can
provide geographic gap-filler service at affordable costs without the need for
additional infrastructure investment.
 
     It is expected that as terrestrial communications services expand to
regions currently underserved or not served by wireline or cellular services,
demand for ORBCOMM System service in these regions may be reduced. ORBCOMM may
also face competition in the future from companies using new technologies and
new satellite systems. A number of these new technologies, even if they are not
ultimately successful, could have an adverse effect on ORBCOMM as a result of
their initial marketing efforts. ORBCOMM's business would be adversely affected
if competitors begin operations or existing or new communications service
providers penetrate ORBCOMM's target markets before completion of the ORBCOMM
System. Additionally, as with any satellite-based system, the ORBCOMM System
will function best when there is an unobstructed line-of-sight between the user
and one or more of the ORBCOMM System satellites overhead, and services will not
be available inside buildings or other similar structures. There can be no
assurance that these characteristics will not adversely affect subscriber demand
for the ORBCOMM System.
 
EMPLOYEES
 
   
     As of September 30, 1996, ORBCOMM had 82 full-time employees, none of whom
is subject to any collective bargaining agreement. The Company's management
considers its relations with employees to be good.

four Earth stations. The Company owns the properties on which the St. Johns,
Arizona and Arcade, New York Earth stations are located and leases, subject to
long-term lease agreements, the properties on which the Ocilla, Georgia and East
Wenatchee, Washington Earth stations are located.

                                   REGULATION
 
UNITED STATES FCC REGULATION
 
  REGULATION OF NVNG SYSTEMS
 
     All commercial non-voice, non-geosynchronous ("NVNG") satellite systems, or
Little LEO systems such as the ORBCOMM System, in the United States are subject
to the regulatory authority of the FCC, which is the U.S. agency with
jurisdiction over commercial uses of the radio spectrum. Little LEOs must obtain
an authorization from the FCC to construct and launch their satellites and to
operate their satellites to provide services in assigned spectrum segments.
 
     In January 1993, the FCC allocated spectrum for NVNG mobile-satellite
services ("MSS") and issued a Notice of Proposed Rulemaking to govern the NVNG
application process. On October 21, 1993, the FCC formally adopted its rules
pertaining to NVNG MSS systems. These rules included provisions regarding
financial qualifications, system size, intersystem coordination and reporting
requirements. These rules were applied to the three applications in the initial
NVNG processing round. Each of these three applications (including OCC's) was
approved by the FCC; however, the ORBCOMM System is the only commercial Little
LEO System to be fully licensed for all segments of its system, including four
Earth stations and its Subscriber Communicators, within the United States.
 
     On November 16, 1994, the FCC closed the application filing period for a
second processing round for NVNG applications, and the FCC has received
applications from eight Little LEO systems (including OCC). The FCC has
indicated that there is insufficient spectrum available to grant each of the
pending applications, and therefore has suggested that its rules for processing
NVNG applications may need to be modified. On May 3, 1996, the FCC issued a
letter to all second round Little LEO system applicants indicating that by late
spring or early summer of 1996 it would issue an order applying its existing
NVNG rules to all second round applications, pending the issuance of a Notice of
Proposed Rulemaking and the formulation of a strategy that would allow it to
license applicants in the second round. See "-- Second Processing Round."
 
  REGULATORY HISTORY OF THE ORBCOMM SYSTEM
 
     On February 28, 1990, nearly two years before the ITU allocated spectrum to
NVNG systems, OCC filed an application with the FCC for a Little LEO system. See
"International Regulation -- ITU Spectrum Allocations." Starsys filed a Little
LEO system application with the FCC several months later, whereupon the FCC
established a cut-off date for the filing of applications to be considered
concurrently with these proposals. A third applicant, VITA, also filed a Little
LEO system application in this initial processing round.
 
     On March 13, 1992 and May 28, 1993, the FCC awarded OCC experimental
licenses to develop and test a limited Little LEO service. These licenses, plus
other licenses previously granted to OCC, permitted the launch of two
satellites, the construction of two ground stations and the development and
production of 1,000 customer terminals and the marketing of revenue-producing
services.
 
     On October 20, 1994, OCC was granted authority by the FCC to construct,
launch and operate an additional 34 satellites located 775 kilometers above
Earth, in four inclined orbital and two near-polar planes, for the purpose of
providing two-way data and message communications and position determination
services in certain specified segments of the radio frequency spectrum (the "FCC
License"). The FCC License grants OCC the authority to operate in certain
segments of the radio frequency spectrum for its uplink and downlink functions.
See "International Regulation -- ITU Spectrum Allocation." The frequency bands
in which the ORBCOMM System is authorized to operate are as follows:
 
<TABLE>
   <S>          <C>
   Uplink:      148.0 - 149.9 MHz
   Downlink:    137.0 - 138.0 MHz and 400.075 - 400.125 MHz
</TABLE>
 
     The FCC License is for private carriage and extends ten years from the
operational date of the first ORBCOMM satellite, FM1, which was April 3, 1995.
The milestone requirements of the FCC License mandate that OCC launch its first
two satellites by December 1998 and its remaining 34 authorized satellites
 
                                       65
<PAGE>   72
 
by December 2000. OCC has already met the first milestone with the launch of its
first two satellites, FM1 and FM2, in April 1995. OCC has set an aggressive
launch schedule for 26 satellites that, if successful, will result in OCC
reaching the second milestone by the end of 1997, subject to receipt of FCC
approval by such date in the event ORBCOMM determines not to deploy the eight
ground spares as a fourth plane. In addition, OCC is required, three years prior
to the expiration of the FCC license, to apply for a license renewal. Although
the FCC has indicated that it is inclined to grant license renewals to existing
NVNG licensees, it is not certain that OCC's license would be renewed should it
apply. See "Risk Factors -- Regulatory Risks -- Licensing Risks  -- Domestic."
 
     At the time the FCC closed the first round of processing for NVNG
applications, ORBCOMM's application was mutually exclusive with Starsys. In an
effort to resolve this mutual exclusivity, the three first round applicants met
and negotiated a Joint Sharing Agreement, executed on August 7, 1992. Using this
Joint Sharing Agreement as a guide, the three first round applicants, the FCC,
existing users of the same frequency bands and adjacent bands and other
interested parties met as a Negotiated Rulemaking Committee to address and
resolve operational and sharing concerns and to propose technical rules to
resolve them. The final rules, based on the proposals of this committee, were
adopted by the FCC and codified in its October 1993 NVNG order. OCC, as well as
the other first round applicants, was permitted to modify its license
application in response to the October 1993 NVNG order. See "-- Regulation of
NVNG Systems."
 
     Under the terms of a coordination agreement between Starsys and OCC, which
was incorporated into the terms of its FCC License, OCC is required to shut down
its left-hand circular polarization ("LHCP") satellite-to-subscriber downlink
channels under certain circumstances when operation of such channels would
interfere with the Starsys system. To further lessen the possibility of
co-polarization interference, OCC also agreed to modify its frequency plan to
locate its LHCP channels in the lower portion of the 137.0-138.0 MHz band. The
FCC imposed these restrictions on OCC's domestic operations but reserved the
right to consider extending these restrictions to OCC's international operations
if notified of actual sharing difficulties between the ORBCOMM System and
Starsys.
 
     The FCC License also provides that the ORBCOMM System is permitted to
operate throughout the 148.0-149.9 MHz band until such time as Starsys is
prepared to launch its first satellite. Once Starsys so notifies the FCC, or
earlier if the FCC requires, OCC has agreed to limit its operations to the upper
half of the 148.0-149.9 MHz band, permitting Starsys to operate its spread
spectrum system in the lower half of the band.
 
     In 1995, the FCC granted OCC licenses to operate four Earth stations in the
continental United States and granted OCC a blanket license to deploy up to
200,000 Subscriber Communicators. Thus, the ORBCOMM System is the only
commercial Little LEO system to be licensed fully for all segments of its system
within the United States.
 
  REQUEST FOR MODIFICATION OF FCC LICENSE
 
     On October 20, 1995, OCC submitted to the FCC the Modification Request,
proposing to reduce each of the ORBCOMM System satellites' subscriber downlinks
operating in the 137-138 MHz band from two to one, while changing the downlink
data rate to a selectable rate of either 4.8 or 9.6 kbps, which would reduce
ORBCOMM's overall bandwidth requirements by 40 kHz. OCC also proposed to
continue to operate at 4.8 kbps in high-inclination planes, and at 56 kbps in
the gateway downlink on all satellites. Although several of the other second
round applicants have filed comments with the FCC opposing the Modification
Request, the Modification Request has several advantages for OCC's opponents, as
well as OCC. The Modification Request would eliminate the need for OCC to shut
down its LHCP when in view of a Starsys Earth station and thus obviate many of
the restrictions imposed on the ORBCOMM System under the terms of the FCC
License. The Modification Request also would free a certain portion of the
allocated spectrum for use by other Little LEO applicants. The Modification
Request would facilitate coordination of the ORBCOMM System with Russian
meteorological satellites currently operating in this bandwidth and could
facilitate OCC's coordination efforts with the proposed French S/80-1 satellite
system. See "-- International Regulation -- ITU Coordination." The Modification
Request has now completed the public comment cycle and OCC recently reached an
agreement with Starsys and NOAA with respect to technical matters raised by the
 
                                       66
<PAGE>   73
 
Modification Request. While OCC believes that the Modification Request will be
granted within the next several months, should the FCC fail to grant the
Modification Request, it could have a material adverse effect on the ORBCOMM
System.
 
  SECOND PROCESSING ROUND
 
     On November 16, 1994, the FCC closed the application filing period for
applications from other proposed NVNG satellite systems. Currently, there are
eight NVNG applicants in the second processing round (including OCC), each of
which proposes to operate in all or part of the same frequencies as the ORBCOMM
System in the United States.
 
     In its own second round application, OCC seeks authorization to construct
12 more satellites to improve its high-latitude coverage over Alaska, Canada and
Europe as well as to provide additional capacity and greater in-orbit
redundancy. This proposal would require the FCC to allocate an additional 90 kHz
of spectrum in the 137-138 MHz downlink to OCC. OCC also has requested use of an
additional 50 kHz in the 149.9-150.05 MHz band for a worldwide gateway uplink.
This spectrum, while registered at the ITU, has not yet been allocated for use
by Little LEO systems, and is currently occupied by U.S. and Russian military
satellite downlinks. OCC anticipates that once this bandwidth is freed by the
United States in 1997, it will be made available by the FCC for use by Little
LEO systems, including the ORBCOMM System, subject to coordination with Russia.
 
     Although the FCC has closed the second processing round for NVNG systems,
it has not yet licensed any of the second round applicants. Prior to the World
Radiocommunication Conference scheduled for November 1995 ("WRC-95"), the FCC
noted that there was insufficient spectrum available to license all of the
second round NVNG applicants, and declined to issue any additional Little LEO
system licenses pending its request for additional spectrum for the Little LEOs
at WRC-95. Significant additional spectrum was not allocated for use by NVNG
services at WRC-95. The FCC has since issued a letter to all second round
applicants indicating that it will issue a Notice of Proposed Rulemaking
intended to establish rules that will allow it to complete the second round of
processing for NVNG applications. See "-- Regulation of NVNG Systems." The FCC
anticipates that it will issue a final order on licensing rules before the end
of 1996 and that it will proceed to licensing immediately thereafter. It is not
clear whether the FCC will in fact grant any of the second round Little LEO
applications or whether it will only grant selected applications. It is
unlikely, however, that the FCC will grant all of the eight pending second round
applications.
 
INTERNATIONAL REGULATION
 
     The ORBCOMM System operates in frequencies which were allocated on an
international basis for use by Little LEO systems at the World Administrative
Radio Conference held in 1992 ("WARC-92"). The United States, on behalf of
various Little LEO service providers, including OCC, pursued international
allocations of additional frequencies for use of Little LEOs at WRC-95 with
limited success, as described above. The United States likely will present a
request for additional frequencies for use by the Little LEOs at WRC-97. See
"-- ITU Spectrum Allocations." In addition to cooperating with these efforts by
the United States to secure additional spectrum for Little LEO systems, OCC is
required to and has in fact, through the FCC, engaged in international
coordination procedures with other countries with respect to other satellite
systems under the aegis of the ITU. OCC also was required, through the FCC and
the U.S. Department of State, to engage in economic and/or technical
coordination with two international satellite systems, Intelsat and Inmarsat.
These coordinations have been completed successfully. Finally, the ORBCOMM
System must receive operational authority from each of the foreign countries in
which it proposes to provide service. It will be the responsibility of the
International Licensee in each country to obtain such authority.
 
  ITU SPECTRUM ALLOCATIONS
 
     The ORBCOMM System operates both in the United States and internationally
using frequencies allocated for Little LEO systems in the International Table of
Frequency Allocations (the "International Table"). The International Table
identifies radio frequency segments that have been designated for specific
 
                                       67
<PAGE>   74
 
radio services by the member nations of the ITU. The International Table is
revised periodically at WRCs. Between WRCs, the member nations of the ITU, in
connection with private industry, prepare and propose recommendations for
international allocations to be considered at the next WRC. Preparatory analyses
and recommendations are considered in appropriate technical study groups for
specific topics.
 
     Little LEO systems require use of radio spectrum on a global basis to reach
their full commercial potential. At WARC-92, with the sponsorship of the U.S.
government and a number of other key administrations, major portions of the 137
to 150 MHz band and a narrow portion of the spectrum band at 400 MHz were
allocated on a global basis to Little LEO systems. The specific frequency
allocations for uplink and downlink operations included the following:
 
<TABLE>
   <S>          <C>
   Uplink:      148.0 - 149.9 MHz (1.9 MHz on a primary basis)
   Downlink:    137.0 - 138.0 (675 kHz on a primary basis; 325 kHz on a
                secondary basis)
                400.15 - 401.00 MHz (850 kHz on a primary basis)
</TABLE>
 
     In addition, 3 MHz of uplink and 3 MHz of downlink frequencies were
allocated on a secondary basis. The band 400.075 - 400.125 MHz licensed for use
by the ORBCOMM System already was allocated previously on a global basis to Time
and Frequency Standard service and, therefore, was not subject to consideration
at WARC-92. The Company's planned use of this bandwidth complies with the
regulations governing its use.
 
     A designation of "primary" places the Little LEO systems on an equal
footing with existing users of these frequencies, subject to the provision that
they not interfere with those services or constrain their growth and, with
respect to certain countries and certain frequency bands, that the Little LEO
systems not claim protection from those other services. A "secondary"
designation means that the other users of the same frequencies have priority
over the Little LEO systems and are not required to accommodate or avoid
interference with them. The procedures for "coordinating" Little LEO services
with other registered users of the band were also established at WARC-92.
 
     At WRC-95, the U.S. government and other administrations sought an
additional allocation of 6.65 MHz of spectrum for Little LEO systems. This
proposal was largely unsuccessful due to the late identification of candidate
bands. Consideration of additional bandwidth allocations is currently scheduled
to be on the agenda for the next WRC scheduled for November 1997.
 
  ITU COORDINATION
 
     The United States, on behalf of OCC, is required to coordinate the
frequencies used by the ORBCOMM System through the ITU. ITU frequency
coordination is a necessary prerequisite to obtaining interference protection
from other NVNG satellite systems. There is no penalty for launching a satellite
system prior to completion of the ITU coordination process, although protection
from interference through this process is only afforded as of the date of
successful completion of the process and notification of the satellite by the
ITU.
 
   
     The United States through the FCC, on behalf of OCC, notified the ITU that
the ORBCOMM System was placed in service on April 3, 1995 and that it has
operated without complaints of interference since that time. The FCC also
informed the ITU that OCC has successfully completed its coordination with all
other administrations except Russia and France. The Company believes that the
Modification Request would facilitate its coordination efforts with Russia and
could facilitate its coordination efforts with France. OCC expects that it will
successfully complete the ITU coordination process with Russia and with France
in the first quarter of 1997, at which time the ORBCOMM System will be
registered with the ITU and accorded protection from interference from any other
subsequently developed system.
    
 
     ITU coordination is also required for the uplink ground segment of the
ORBCOMM System, but is the responsibility of individual administrations.
Depending on the location of particular ground stations, the applicable
coordination distance specified in the ITU procedures may extend across
international boundaries and require coordination by more than one government
authority. For example, two of the four U.S. Earth
 
                                       68
<PAGE>   75
 
stations have a coordination distance that extends into Canada, and thus require
coordination with Canada prior to ITU notification or registration.
 
     At WRC-95, France proposed a reduction in the threshold for coordination
with terrestrial services, which would require additional coordination of mobile
satellite systems. This proposed change was not adopted at WRC-95, but there can
be no assurance that it will not be proposed and adopted at the next WRC
scheduled for 1997, or that, if adopted, additional coordination requirements
would not be imposed on the ORBCOMM System, to the extent that OCC may not have
completed the ITU coordination process.
 
  COORDINATION WITH INTELSAT AND INMARSAT
 
     Pursuant to the Intelsat treaty, international satellite operators are
required to demonstrate that they will not cause economic or technical harm to
Intelsat. OCC was notified in March 1995 that this coordination with Intelsat
has been completed successfully.
 
     The Inmarsat treaty similarly requires both technical and economic harm
coordination. OCC was notified in October 1995 that it had successfully
completed both technical and economic coordination with Inmarsat.
 
  REGULATION OF SERVICE PROVIDERS
 
   
     Primary responsibility for obtaining local regulatory approval to offer
ORBCOMM System services in countries outside the United States will reside with
the various International Licensees. In all but one case, Russia, the proposed
International Licensees are private companies, reflecting the expectation that
the ORBCOMM System will be licensed as a value-added service rather than as a
regulated basic service. The Company's proposed International Licensees have had
discussions with regulators in the major target countries and have advised the
Company that such discussions indicate that favorable regulatory treatment can
be anticipated.
    
 
     The process for obtaining operating approval in foreign countries generally
conforms to the following process. The International Licensee requests operating
authority from the appropriate national regulatory body, which has the sole
authority to grant an operating license. Obtaining such local regulatory
approvals normally requires, among other things, that the International Licensee
demonstrate the absence of interference to other authorized uses of the spectrum
in each country. In some countries, this process may take longer due to heavier
shared use of the applicable frequencies and, in certain other countries, may
require reassignment of some existing users. The national regulatory authority
will be required to associate with the ORBCOMM ITU submission. The national
regulatory authority also will be required to submit so-called Appendix 3
information to the ITU in order to coordinate and protect ORBCOMM's Earth
stations in the territory or region from interference by other ground systems.
 
   
     ORBCOMM International has to date executed three Service License Agreements
with International Licensees, ORBCOMM Europe, ORBCOMM Canada and Celcom. The
International Licensees or proposed International Licensees in Canada,
Venezuela, Chile, Japan and Morocco are in the process of seeking authority to
operate. The Company has been advised by its proposed International Licensees
that experimental or preliminary operating authority for the ORBCOMM System has
been granted in Canada, Japan, Italy, Venezuela and Colombia.
    
 
     The Company provides technical and regulatory assistance to its proposed
International Licensees in pursuing operating authority. The assistance provided
by the Company includes actual in-country demonstrations that the ORBCOMM System
can share use of the allocated spectrum with existing users while causing no
harmful interference or constraining operations and growth of those systems.
While International Licensees have been selected, in part, based upon their
perceived qualifications to obtain the requisite foreign regulatory
authorizations, there can be no assurance that they will be successful in doing
so, and if they are not successful, service on the ORBCOMM System will not be
available in such countries. In addition, the continued operations of the
International Licensees may be subject to other regulatory requirements and
changes in each foreign jurisdiction.

                    RELATIONSHIPS AMONG THE ORBCOMM PARTIES
 
STRUCTURE
 
     ORBCOMM is a Delaware limited partnership formed in 1993 to develop,
construct, operate and market the ORBCOMM System. The general and limited
partnership interests in ORBCOMM are held by OCC, a Delaware corporation and
subsidiary of Orbital, a Delaware corporation, and Teleglobe Mobile, a Delaware
general partnership that is controlled by Teleglobe, a Canadian corporation.
ORBCOMM holds general and limited partnership interests with a 98% Participation
Percentage in each of ORBCOMM USA, a Delaware limited partnership, and ORBCOMM
International, a Delaware limited partnership. OCC holds general and limited
partnership interests in ORBCOMM USA with a 2% Participation Percentage and, by
virtue of its control of one-half of the Participation Percentage held by
ORBCOMM, controls the operational and financial affairs of ORBCOMM USA. See "The
Partnership Agreements." Teleglobe Mobile holds general and limited partnership
interests in ORBCOMM International with a 2% Participation Percentage and, by
virtue of its control of one-half of the Participation Percentage held by
ORBCOMM, controls the operational and financial affairs of ORBCOMM
International. See "The Partnership Agreements." ORBCOMM, Orbital, OCC,
Teleglobe and Teleglobe Mobile are sometimes referred to herein as the "ORBCOMM
Parties."
 
     Capital, a Delaware corporation formed in July 1996, is acting as co-Issuer
for the Senior Notes. Capital is a wholly owned subsidiary of ORBCOMM, has
nominal assets and will not conduct any operations. Certain institutional
investors that might otherwise be limited in their ability to invest in
securities issued by partnerships by reason of the investment laws of their
states of organization or their charter documents, may be able to invest in the
Senior Notes because Capital is a co-issuer.

     The ORBCOMM Parties have entered into a series of agreements or
arrangements for the development, construction, operation and marketing of the
ORBCOMM System. The following paragraphs are a summary of the material
provisions of certain of these agreements and are qualified in their entirety by
reference to the actual agreements, copies of which are available from ORBCOMM.
 
MASTER AGREEMENT
 
     As of June 30, 1993, Orbital, OCC, Teleglobe and Teleglobe Mobile entered
into the Master Agreement that sets forth the principles upon which the parties
have agreed to develop, construct and operate the ORBCOMM System. The Master
Agreement subsequently has been amended and restated and currently provides for
the following:
 
     Covenants Relating to OCC.  Orbital and OCC have agreed: (i) to preserve
OCC's corporate existence; (ii) to use all commercially reasonable efforts to
obtain and maintain all material U.S. operating licenses and permits necessary
for the construction, operation and marketing of the ORBCOMM System; (iii) so
long as OCC holds any FCC authorizations, that OCC will (a) remain a subsidiary
of Orbital, other than as a result of options granted under the Orbital
Communications Corporation 1992 Stock Option Plan; (b) carry on no business
other than the construction, operation and marketing of the ORBCOMM System or
business that is in furtherance, or in connection with the expansion of the
ORBCOMM System; (c) remain the sole holder of all FCC authorizations required
for the construction, launch and operation of the ORBCOMM System (other than FCC
authorization for individual user transceivers and FCC authorizations held by
ORBCOMM and ORBCOMM USA); (d) subject to certain exceptions in accordance with
the Definitive Agreements, not grant, create, assume, incur or suffer to exist
any lien affecting OCC or any of its property, rights, revenues or assets; (e)
subject to certain exceptions in accordance with the Definitive Agreements, not
sell, transfer, convey, lease or otherwise dispose of any assets; (f) not
consolidate, merge or amalgamate with any other person; (g) subject to certain
exceptions in accordance with the Definitive Agreements, not create, amend or
repeal any by-laws or modify the OCC certificate of incorporation; (h) subject
to certain exceptions in accordance with the Definitive Agreements, not make any
loans or give any financial guarantees for the obligations of any other party;
and (i) not make any assignment for the benefit of creditors or subject OCC to
any bankruptcy or insolvency law or take steps to wind up or terminate OCC's
corporate existence or engage in any financial restructuring. Additionally,
Orbital has agreed, as long as OCC holds the FCC License, not to dispose of any
debt interest in OCC.
 
     Guarantees.  Orbital has unconditionally and absolutely guaranteed the full
and punctual payment of all of OCC's payment obligations under the Definitive
Agreements to which OCC is a party. Teleglobe has unconditionally and absolutely
guaranteed the full and punctual payment of all of Teleglobe Mobile's payment
obligations under the Definitive Agreements to which Teleglobe Mobile is a
party.
 
     Change of Control.  In the event of a Change in Control of Orbital or
Teleglobe (a "Change of Control Party"), Teleglobe Mobile or OCC, as the case
may be (the "Non-Change of Control Party"), has the option: (i) for a period of
180 days from the Change of Control to require the Change of Control Party to
purchase the Non-Change of Control Party's interest in each of ORBCOMM, ORBCOMM
USA and ORBCOMM International at an aggregate price equal to the greater of (a)
the Non-Change of Control Party's aggregate Unrecouped Capital Preferences in
such partnerships and (b) the Non-Change of Control Party's direct Participation
Percentage in each such partnership multiplied by the fair market value (as
defined) of each such partnership; or (ii) to cause the general partners of
ORBCOMM to adopt a resolution providing that, in the event there is a deadlock
on a matter requiring the approval of a Majority in Interest of the partners,
the President of ORBCOMM shall be entitled to decide on such matter by way of
casting a vote or otherwise, as deemed appropriate by the Non-Change of Control
Party, notwithstanding any contrary provision set forth in the ORBCOMM
Partnership Agreement. Subject to the receipt of all necessary government
approvals, upon a Change of Control of Orbital, Orbital agrees to cause OCC to
transfer to ORBCOMM USA all FCC licenses then held by OCC relating to the
construction, launch or operation of the ORBCOMM System.
 
     In the event that OCC should become a common carrier or a CMRS
provider -- either by virtue of a change in the ORBCOMM System's regulatory
classification by the FCC from private-carrier to common-
 
                                       75
<PAGE>   82
 
carrier or CMRS status, or by virtue of a change in its service offerings that
would convert OCC from a private carrier to a common carrier or a CMRS
provider -- ORBCOMM USA might be precluded from acquiring the FCC licenses from
OCC, due to the extent of alien ownership in ORBCOMM USA as a result of
Teleglobe Mobile's indirect interest in ORBCOMM USA.
 
SYSTEM CONSTRUCTION AGREEMENT
 
     Under the terms of the System Construction Agreement, ORBCOMM has agreed to
develop, construct, deploy, manage and operate, subject to OCC's ultimate
control, the ORBCOMM System satellites and the System Assets, in consideration
for which OCC is obligated to remit to ORBCOMM, on a quarterly basis, OCC's
allocated portion of the System Charge, provided, however, that, if the Output
Capacity Charge for any quarter is less than 1.15% of Total Aggregate Revenues,
then OCC shall not be required to pay any portion of the System Charge for such
calendar quarter. For a description of the System Charge, see "The Partnership
Agreements -- System Charge." For a description of the Output Capacity Charge,
see "-- System Charge Agreement."
 
     OCC has granted to ORBCOMM under the System Construction Agreement the
right to market, sell, lease and franchise all output capacity outside the
United States.
 
     ORBCOMM has agreed to indemnify OCC from and against any claim with respect
to an infringement or other violation of any copyright, trademark or patent or
other validly registered enforceable intellectual property right of any third
party for any items constructed by ORBCOMM pursuant to the authority granted in
the System Construction Agreement, but only to the same extent as the
indemnification received by ORBCOMM from Orbital pursuant to the Procurement
Agreement.
 
PROCUREMENT AGREEMENT
 
   
     ORBCOMM and Orbital have entered into the Procurement Agreement pursuant to
which Orbital has undertaken the overall design, development, construction,
integration, test and operation of the ORBCOMM System. The Procurement Agreement
was the result of arm's length negotiations between Orbital and Teleglobe Mobile
that took place prior to Teleglobe Mobile's decision to exercise an option to
invest an approximately $75 million in additional equity in the ORBCOMM project.
Under the Procurement Agreement, Orbital will develop, construct and deliver to
ORBCOMM 34 satellites and complete the construction and design of the Satellite
Control Center and of the four Earth stations comprising the U.S. ground segment
of the ORBCOMM System. Orbital will also provide to ORBCOMM launch services for
24 satellites using three Pegasus XL launch vehicles. Orbital will also provide
in-orbit check-out support for up to 120 days after each of the three satellite
launches.
    
 
   
     ORBCOMM has agreed to pay Orbital approximately $163 million for satellite
construction, launch services and other work specified in the Procurement
Agreement plus certain incentive fees. Upon execution of the Procurement
Agreement, ORBCOMM paid to Orbital approximately $17.2 million representing
reimbursement for costs incurred through the date thereof. Following execution
of the Procurement Agreement, Orbital invoices ORBCOMM monthly for a maximum of
90% of its costs incurred during such month. The remaining ten percent of costs
incurred in any month, as well as the remaining balance of the fixed-price
contract amount, may be invoiced only upon completion of certain specified
project milestones.
    
 
     Optional Work.  The Procurement Agreement provides for additional work and
services to be performed at the option of ORBCOMM, including: (i) launch
services for an additional plane of eight satellites using one additional
Pegasus XL launch vehicle, and in-orbit check-out support for up to 120 days
after such optional launch; (ii) a replacement constellation of 32 satellites
(including launch services using four Pegasus XL launch vehicles) in accordance
with the specifications contained in the Procurement Agreement at a cost of
$166.1 million (subject to adjustment for inflation and excluding taxes, if any,
and the cost of launch and satellite insurance); and (iii) a one-time option to
request Orbital to provide a standard Taurus launch vehicle rather than a
Pegasus XL launch vehicle for any launch procured pursuant to the Procurement
Agreement; this option may be exercised by ORBCOMM on or prior to September 12,
1998 at a price to be negotiated, but which will not exceed $21 million.
 
                                       76
<PAGE>   83
 
     Regulatory Matters.  Under the terms of the Procurement Agreement, Orbital
is required to use all commercially reasonable efforts directly or through OCC:
(i) to obtain and maintain the required U.S. regulatory authority needed to
construct, launch and operate the satellites and operate the ORBCOMM System;
(ii) obtain and maintain FCC regulatory authority for the operation of
Subscriber Communicators for use in connection with the ORBCOMM System; and
(iii) to take reasonable actions in any regulatory proceedings to defend any
claims against any regulatory authority granted to Orbital or OCC in connection
with the ORBCOMM System or to oppose any application by competing systems that
use frequencies below 1 GHz. ORBCOMM has agreed to pay or reimburse Orbital or
OCC for all out-of-pocket expenses and internal costs incurred in connection
with Orbital's or OCC's efforts.
 
     Delivery; Title and Risk of Loss.  Under the Procurement Agreement,
delivery of the launch vehicle and satellites occurs on separation of the launch
vehicle from Orbital's L-1011 aircraft. At such time, title to and risk of loss
or damage passes to ORBCOMM and ORBCOMM's sole remedy for launch failure,
defects or failures to conform to applicable specifications is limited to: (i)
non-payment to Orbital of the specified milestone payment and any satellite
performance incentive payment; and (ii) termination of the Procurement
Agreement.
 
     Delivery of the remaining Earth station and Satellite Control Center
efforts set forth in the Procurement Agreement occurs in accordance with the
terms of the Procurement Agreement. Title to, and risk of loss of or damage,
passes to ORBCOMM on successful completion of the acceptance test procedures for
such work as set forth in the Procurement Agreement.
 
     Incentive Payments.  In addition to the above prices for work and service,
Orbital is entitled to receive under the Procurement Agreement certain
performance incentive payments. Payments are to be made on a per-plane basis
with the incentive to be earned monthly for each complete month that there are a
specified minimum number of working satellites in the plane. The minimum number
of working satellites in a plane is seven during the first 30 months of the
on-orbit performance incentive period and six during the second 30 months of the
on-orbit performance period.
 
SYSTEM CHARGE AGREEMENT
 
     OCC and ORBCOMM USA have entered into the System Charge Agreement for the
purpose of providing for the use by ORBCOMM USA of all of the output capacity of
the ORBCOMM System within the United States and for the exclusive use by ORBCOMM

granted to Teleglobe Mobile the exclusive right in the Non-U.S. Area to market,
sell, lease and franchise all ORBCOMM System output capacity and exclusive use
of the System Assets located in the Non-U.S. Area. Teleglobe Mobile, in turn,
has granted to ORBCOMM International the exclusive right in the Non-U.S. Area to
market, sell, lease and franchise all ORBCOMM System output capacity and
exclusive use of the System Assets located in the Non-U.S. Area. OCC ultimately
has retained all rights in and to, and neither Teleglobe Mobile nor ORBCOMM
International has been granted rights to, the ORBCOMM System.
 
     System Charge.  In consideration of the grant to Teleglobe Mobile of the
exclusive right to market, sell, lease and franchise all ORBCOMM System output
capacity in the Non-U.S. Area, Teleglobe Mobile agrees to remit to ORBCOMM
Teleglobe Mobile's allocated portion of the System Charge for that calendar
quarter calculated in accordance with the ORBCOMM Partnership Agreement. If the
International Output Capacity Charge for such calendar quarter is less than
1.15% of Total Aggregate Revenues, then Teleglobe Mobile is not required to pay
any portion of the System Charge for such calendar quarter.
 
     International Output Capacity Charge.  In consideration of the grant by
Teleglobe Mobile to ORBCOMM International of the exclusive right to market,
sell, lease and franchise all ORBCOMM System output capacity in the Non-U.S.

<PAGE>   85
 
entities in the provision of certain LEO satellite services during the term of
the agreement and for a period of one year thereafter.
 
     Orbital and Teleglobe agree that for the duration of the agreement and for
one year thereafter, they will not, directly or indirectly or in any capacity,
except in connection with the fulfillment of their respective obligations under
any of the Definitive Agreements: (i) carry on, engage, participate, invest or
have an equity or any financial interest in the marketing, construction,
development or management of any business or enterprise that competes with
Orbital or Teleglobe or their respective affiliates in offering commercial, LEO
non-voice satellite communications services operating in the 137-150 MHz band or
such other frequency allocated to the Little LEO mobile satellite service below
1 GHz, provided, however, OCC and Orbital are permitted to: (a) sell satellites,
launch vehicles, launch services and communications services to non-commercial

or (iii) employ any person to work on or represent the ORBCOMM System who will
also work on or represent another mobile communications system, without first
notifying the President of ORBCOMM.
 
     Neither of Orbital or Teleglobe will be in default of its obligations under
this portion of the Proprietary Information and Non-Competition Agreement by
virtue of holding for portfolio purposes as a passive investor no more than 5%
of the issued and outstanding public equity securities of a corporation.
 
     Indemnification.  Orbital and Teleglobe agree to indemnify and save
harmless one another and their respective affiliates (an "Indemnified Party")
from and against any claims, demands, actions, causes of action, judgments,
damages, losses, liabilities, costs or expenses that may be made against any of
them as a result of, arising out of or relating to any violation, contravention
or breach of the Proprietary Information and Non-Competition Agreement by a
party who is not an Indemnified Party.
 
     Termination.  The Proprietary Information and Non-Competition Agreement
shall terminate upon the earlier of OCC or Teleglobe Mobile ceasing to be both a
general and a limited partner of ORBCOMM.
 
ADMINISTRATIVE SERVICES AGREEMENT
 
     Under the terms of the Administrative Services Agreement, Orbital has
agreed to provide to the Company, ORBCOMM USA and ORBCOMM International defined
office space for a total price of $15,200 per month. Orbital also has agreed to
provide ORBCOMM with certain occupancy services for a fixed monthly price of
$50,000. The services includes security and facilities support, MIS, telephone
switchboard and communication services and other support services. Orbital
provides various administrative services to ORBCOMM for a fixed monthly fee of
$15,000, including accounting support, payroll processing, miscellaneous
purchasing services and personnel services. Orbital also extends to ORBCOMM
employees (to the extent possible) participation in various benefit and
insurance plans. Orbital also has agreed to provide to ORBCOMM executive
management services payable on a time and materials basis, limited to $9,000 per
month.
 
     The Administrative Services Agreement continues in effect so long as any
category of services are being provided by Orbital, provided that ORBCOMM has
the right to terminate all or part of the services being provided upon 90 days
prior notice to Orbital, subject, in a case of a termination of services within
a specific category of services, to an agreement on the price to perform the
remaining services. The prices for the services are fixed through the end of
1996. The parties will negotiate the prices for such services and office space
for subsequent years, provided that prices for 1997 will not be more than 10%
higher than the prices in effect in 1996.

                           THE PARTNERSHIP AGREEMENTS
 
     The following paragraphs are a summary of certain provisions of the
Partnership Agreements of each of ORBCOMM, ORBCOMM USA and ORBCOMM International
and such summary is qualified in its entirety by reference to such Partnership
Agreements. Each of the Partnership Agreements are substantially identical.
Unless otherwise described herein, references to the "Partnership" constitute
references to ORBCOMM, ORBCOMM USA and ORBCOMM International, collectively, and
references to the "Partnership Agreement" constitute references to the
Partnership Agreements of ORBCOMM, ORBCOMM USA and ORBCOMM International,
collectively.
 
     Organization and Duration.  The Partnership will dissolve on December 31,
2013, unless sooner dissolved on the written consent of all of the General
Partners or upon removal, withdrawal, resignation, liquidation or bankruptcy of
the last remaining General Partner (unless a new General Partner is appointed
within 90 days with the unanimous consent of the remaining partners).
 
     General Partners; Management.  OCC and Teleglobe Mobile are the general
partners of ORBCOMM. ORBCOMM and OCC are the general partners of ORBCOMM USA and
ORBCOMM and Teleglobe Mobile are the general partners of ORBCOMM International.
The management of the Partnership is the exclusive responsibility of the General
Partners and, except as provided by law or except as specified in the
Partnership Agreement and summarized below, the act of the General Partners
holding a majority of the Participation Percentages of the Partnership (a
"Majority in Interest") is the act of the Partnership.
 
     The Partnership Agreement provides for meetings of the General Partners to
be called by any General Partner. It is the current practice of the Partnerships
to hold regular meetings of the General Partners on at least a quarterly basis.
Each General Partner is represented at the meetings by up to three authorized
representatives, although one representative of each general partner is entitled
to vote such General Partner's Participation Percentage.
 
     The Partnership Agreement provides for the election of officers to provide
for the day-to-day operation of the Partnership. Officers are nominated by the
President of the Partnership and elected by the General Partners. Officers
exercise the authority granted to such officers by the General Partners. Under
the terms of the ORBCOMM Partnership Agreement, the General Partners are
required to appoint one or more officers to have authority to act for the
Partnership with respect to the Procurement Agreement. For a description of the
Procurement Agreement, see "Relationships Among the ORBCOMM
Parties -- Procurement Agreement." Officers are subject to removal for any
reason by approval of the General Partners. For a description of the current
officers of the Partnership, see "Management."
 
     Certain Actions.  Under the Partnership Agreement, the approval of at least
86% of the Participation Percentages held by the General Partners is required
to: (i) transfer all or substantially all the assets of the Partnership; (ii)
merge or consolidate the Partnership with any other person; (iii) permit the
entry by the Partnership into any additional lines of business; (iv) admit any
new Partner to the Partnership; (v) subject to certain exceptions in furtherance
of the business of the Partnership, cause the Partnership to borrow any amount
on a recourse basis or any amount in excess of $5 million on a non-recourse
basis; (vi) subject to certain exceptions set forth in the Partnership
Agreement, enter into any transaction with an affiliate of a General Partner
(excluding the Definitive Agreements); (vii) select or remove the independent
certified public accountant for the Partnership or adopt, or modify in any
material respect, any significant accounting policy or tax policy; (viii) make
on behalf of the Partnership an assignment for the benefit of creditors, decide
on behalf of the Partnership to subject the Partnership to any proceedings under
any bankruptcy or insolvency law, decide to avail the Partnership of the benefit
of any other legislation for the benefit of debtors, or take steps to wind up or
terminate the existence of the Partnership; (ix) delegate any of the powers of
the Partnership; (x) determine the value of the Partnership for purposes of the
Master Agreement; and (xi) amend any provision of the Partnership Agreement. No
amendment to the Partnership Agreement may: (i) decrease the capital account or
increase the amount required to be contributed by a Partner without the consent
of such Partner; or (ii) amend the provisions of, or adopt any provisions
inconsistent with, Sections 6.2, 6.3 and 6.4 of the Partnership Agreement, which
provisions regard super-majority approval
 
                                       80
<PAGE>   87
 
requirements for certain actions of the Company, enforcement of the Definitive
Agreements and meetings of the General Partners, respectively.
 
     The Partnership Agreement also provides that: (i) any action of the
Partnership with respect to the enforcement by it of its rights under any
Definitive Agreement or other contract or agreement to which any General Partner
or any affiliate thereof is a party with respect to a breach, default or dispute
by such General Partner or affiliate, requires the approval of General Partners
having a majority of the Participation Percentages held by the General Partners
other than such General Partner; and (ii) subject to the limitations set forth
in (i) above, in the event that a Majority in Interest of the General Partners,
each acting in the best interests of the Partnership, shall be unable to agree
on exercising or enforcing the rights of the Partnership under the Procurement
Agreement including, without limitation, the rights to exercise the options
thereunder, to stop work, to request changes and to send notices to preserve or
exercise any such rights, then the President of the Partnership shall decide on
the appropriate action with respect to such rights, and the Partnership shall
then act upon such decision. The ORBCOMM Partnership Agreement also provides
that so long as ORBCOMM holds voting rights in either of ORBCOMM USA or ORBCOMM
International, each General Partner shall be entitled to exercise directly a
fraction of ORBCOMM's rights determined by dividing such General Partner's
Participation Percentage by the total Participation Percentages held by all
General Partners.
 
     Capital Contributions.  Pursuant to the terms of the ORBCOMM Partnership
Agreement, OCC is obligated to contribute up to approximately $75 million, and
Teleglobe Mobile is obligated to contribute up to approximately $85 million, of
capital to ORBCOMM, all of which was contributed prior to the consummation of
the Old Notes Offering.
 
     Under the terms of the ORBCOMM USA Partnership Agreement, OCC and the
Company together were obligated to contribute nominal capital to ORBCOMM USA in
the amount of $10,000. Under the terms of the ORBCOMM International Partnership
Agreement, Teleglobe Mobile and the Company together were obligated to
contribute nominal capital to ORBCOMM International in the amount of $10,000.
Pursuant to a resolution adopted by the General Partners of ORBCOMM on September
12, 1995, ORBCOMM agreed that until December 31, 1996, ORBCOMM would provide
interest-free loans to each of ORBCOMM USA and ORBCOMM International in an
amount equal to their monthly net cash requirements so long as such cash
requirements are generally in accordance with a budget approved by ORBCOMM or
the executive management of ORBCOMM.
 
     System Charge.  The ORBCOMM Partnership Agreement provides for the
remittance of the System Charge by OCC and Teleglobe to ORBCOMM each calendar
quarter. OCC's allocated portion of the System Charge for a calendar quarter is
equal to the Output Capacity Charge for such calendar quarter minus 1.15% of the
Total Aggregate Revenues. Teleglobe Mobile's allocated portion of the System
Charge for a calendar quarter is equal to the International Output Capacity
Charge for such calendar quarter minus 1.15% of the Total Aggregate Revenues.
 
     Indemnification.  The Partnership has agreed to indemnify its General
Partners and all of their respective officers, directors, partners, employees,
and agents (each an "Indemnitee") from and against any and all claims or
liabilities arising out of or in connection with any action taken or omitted by
the General Partners or the officers of the Partnership pursuant to authority
granted by the Partnership Agreement so long as such Indemnitee's conduct did
not constitute gross negligence, willful or wanton misconduct or bad faith. The
Partnership Agreement further provides that the General Partners and all of
their respective officers, directors, partners, employees and agents (each a
"General Partner Person") will not be liable to the Partnership or the limited
partners for any act or omission by such General Partner Person, except as such
act or omission results from gross negligence, willful or wanton misconduct or
bad faith.
 
     Liquidation and Distribution of Proceeds.  Upon the dissolution of the
Partnership, the General Partners, or, in the case of the removal, withdrawal,
resignation, liquidation or bankruptcy of the last remaining General Partner,
one of the limited partners elected by a majority vote of the limited partners,
shall act as liquidator to wind up the Partnership. The liquidator shall have
full power and authority to sell, assign and encumber any or all of the
Partnership's assets and to wind up and liquidate the affairs of the Partnership
in an orderly and business-like manner. All proceeds from liquidation shall be
distributed in the following
 
                                       81
<PAGE>   88
 
order of priority: (i) to the payment of the debts and liabilities of the
Partnership and expenses of liquidation; (ii) to the setting up of such reserves
as the liquidator may reasonably deem necessary for any contingent liability of
the Partnership; and (iii) the balance to the Partners in the proportions of
their positive capital account balances, if any (determined after taking into
account all allocations of Net Income and Net Loss for the year of liquidation).
 
     Allocations and Distributions.  Allocations of Net Income and Net Loss of
the Partners shall generally be allocated to the capital accounts of Partners in
proportion to their Participation Percentage. Except as set forth below, or in
the case of liquidating distributions, the amount and timing of distributions by
the Partnership are determined in the discretion of the General Partners. All
distributions will be made to Partners first to return to the Partners their
Capital Preference and, thereafter, to the Partners in proportion to their
Participation Percentages. The Partnership Agreement provides for a minimum
distribution each year in an amount sufficient to ensure that each Partner shall
have received at least an amount equal to the product of: (i) 40% multiplied by
(ii) the lesser of (a) such Partner's distributive share of the Partnership's
taxable income for the preceding year, and (b) the excess, if any, of cumulative
Net Income over cumulative Net Loss allocated to such Partner since the
inception of the Partnership.

                          DESCRIPTION OF SENIOR NOTES
 
GENERAL
 
     The Old Notes were, and the Exchange Notes will be, issued pursuant to the
Indenture among the Company, Capital, the Guarantors and Marine Midland Bank, as
trustee (the "Trustee"). The terms of the Exchange Notes are identical in all
material respects to the Old Notes, except that the Exchange Notes have been
registered under the Securities Act, and therefore will not bear legends
restricting their transfer. The Senior Notes are secured pursuant to a Pledge
Agreement (the "Pledge Agreement") between the Issuers and the Trustee as
Collateral Agent (the "Collateral Agent"). Upon the issuance of the Exchange
Notes, the Indenture will be subject to and governed by the Trust Indenture Act
of 1939, as amended (the "Trust Indenture Act").
 
     The terms of the Exchange Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act as an
effect on the date of the Indenture. The Exchange Notes are subject to all such
terms, and Holders of Exchange Notes are referred to the Indenture and the Trust
Indenture Act for a statement thereof. The following summary of certain
provisions of the Indenture and the Pledge Agreement do not purport to be
complete and are qualified in their entirety by reference to all the provisions
of the Indenture and the Pledge Agreement, including the definitions in each of
such instruments and agreements of certain terms used below.
 
     The Senior Notes are the joint and several obligations of the Issuers. The
Senior Notes are senior obligations of the Issuers, rank senior in right and
priority of payment to all subordinated indebtedness of the Issuers and rank
pari passu in right and priority of payment with all other indebtedness of the
Issuers that is not expressly so subordinated, including indebtedness under the
MetLife Note (which aggregated approximately $3.8 million as of June 30, 1996),
except to the extent of the collateral securing such MetLife Note. The Senior
Notes are secured to the extent set forth below under "-- Security." The Issuers
have no indebtedness that is expressly subordinated in right and priority of
payment to the Senior Notes.
 
     The obligations of the Issuers under the Senior Notes are jointly and
severally guaranteed by OCC, Teleglobe Mobile, ORBCOMM USA and ORBCOMM
International (collectively, the "Guarantors"). See "-- Guarantees." The
guarantee of each of the Guarantors rank senior in right and priority of payment
to all subordinated indebtedness of such Guarantor and rank pari passu in right
and priority of payment with all other indebtedness of such Guarantor that is
not expressly so subordinated to such guarantee, except to the extent of any
collateral securing such other indebtedness. The guarantees by the Guarantors
are non-recourse to the shareholders and/or partners of such Guarantors
(including Orbital, Teleglobe and TRI) and no shareholder or partner of such
Guarantors will have any liability for any claim under the Senior Notes. The
only assets of Teleglobe Mobile are such entity's investments in the Company and
ORBCOMM International; the only significant assets of OCC are such entity's
investments in the Company and ORBCOMM USA and the FCC License.
 
     As of the date of the Indenture, the Company has no Subsidiaries other than
Capital, which is a wholly owned Subsidiary of the Company, has nominal assets
and does not conduct any operations. Under certain circumstances, the Credit
Parties will be able to designate future Subsidiaries that they create or
acquire as Unrestricted Subsidiaries. Unrestricted Subsidiaries will not be
subject to the restrictive covenants set forth in the Indenture.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Senior Notes are limited in an aggregate principal amount to $170
million. The Senior Notes will mature on August 15, 2004. Interest on the Senior
Notes will accrue at the rate of 14% per annum (the "Fixed Interest") and will
be payable semi-annually in arrears on February 15 and August 15 of each year,
commencing on February 15, 1997, to Holders of record on the immediately
preceding February 1 and August 1. Fixed Interest on the Senior Notes will
accrue from the most recent date to which interest has been paid or, if no Fixed
Interest has been paid, from August 7, 1996 (the "Issue Date"). Fixed Interest
on the Senior Notes will be computed on the basis of a 360-day year comprised of
twelve 30-day months.
 
                                       83
<PAGE>   90
 
     In addition, the Senior Notes bear Revenue Participation Interest,
calculated as described below, from the Issue Date to the date of payment of the
Senior Notes. Installments of accrued or deferred Revenue Participation Interest
accrued through the Accrual Period (as defined herein) last ended will become
due and payable semi-annually on each February 15 and August 15 after the Issue
Date, commencing on February 15, 1997, to the Holders of record at the close of
business on the preceding February 1 or August 1. Additionally, all installments
of accrued or deferred Revenue Participation Interest will become due and
payable (and may not be further deferred) with respect to any principal amount
of the Senior Notes that matures (whether at stated maturity, upon acceleration,
maturity of repurchase obligation or otherwise) upon such maturity of such
principal amount of the Senior Notes.
 
     The Issuers, at their option, may defer payment of all or a portion of
Revenue Participation Interest then otherwise due if, and only to the extent
that, (a) the payment of such portion of Revenue Participation Interest will
cause the Credit Parties' Fixed Charge Coverage Ratio for the four consecutive
fiscal quarters last completed prior to such interest payment date to be less
than 2.0:1 on a pro forma basis after giving effect to the assumed payment of
such Revenue Participation Interest (but may not defer such portion which, if
paid, will not cause such Credit Parties' Fixed Charge Coverage Ratio to be less
than 2.0:1); provided, however, that for purposes of calculating such Credit
Parties' Fixed Charge Coverage Ratio for any period, the amount representing
Revenue Participation Interest that has been deferred or will be deferred for
such period shall not be included in the calculation of Credit Parties' Fixed
Charges for such period and (b) the principal of the Senior Notes corresponding
to such Revenue Participation Interest has not then matured and become due and
payable (at stated maturity, upon acceleration, upon maturity of repurchase
obligation or otherwise). Revenue Participation Interest that is deferred shall
become due and payable on the earlier of (i) the next succeeding interest
payment date on which such Revenue Participation Interest is not permitted to be
deferred, and (ii) upon the maturity of the corresponding principal of the
Senior Notes (whether at stated maturity, upon acceleration, upon maturity of
repurchase obligation or otherwise). No interest will accrue on any Revenue
Participation Interest deferred and which has not yet become due and payable. To
the extent permitted by law, interest will accrue on overdue Fixed Interest or
Revenue Participation Interest at the same rate as the Fixed Interest plus one
percent (1%) per annum.
 
     Each installment of Revenue Participation Interest will be calculated to
accrue (an "Accrual Period") from, but not including, the most recent date
through which Revenue Participation Interest has been paid or provided for or
through which Revenue Participation Interest has been calculated and deferred
(or from and including the Issue Date if no installment of Revenue Participation
Interest has been paid, provided for or deferred) to, and including, either (a)
the last day of the next Semi-annual Period if the corresponding principal of
the Senior Notes has not become due and payable (or December 31, 1996 if no
installment of Revenue Participation Interest has been paid, provided for or
deferred) or (b) the date of payment if the corresponding principal of the
Senior Notes has become due and payable (whether at stated maturity, upon
acceleration, upon maturity of repurchase obligation or otherwise). With respect
to each Accrual Period, Revenue Participation Interest will accrue daily on the
principal of each Senior Note outstanding during such period as follows: (i) for
each day during each month that ends during such Accrual Period and which month
ends at least 25 days prior to the date of payment, an amount equal to 1/30th of
the Monthly Revenue Participation Interest on the Senior Note for such month
until all of such Monthly Revenue Participation Interest on the Note shall be
accrued (and all of such month's Monthly Revenue Participation Interest on the
Senior Note shall be accrued by the last day of such month) and (ii) for any day
in any remaining period, 1/30th of the prior month's Monthly Revenue
Participation Interest on the Senior Notes.
 
     Any reference in this Prospectus to "accrued and unpaid interest" on the
Senior Notes includes the amount of Fixed Interest, unpaid Revenue Participation
Interest and Liquidated Damages, if any, due and payable thereon.
 
     Principal of, premium (if any), interest and Liquidated Damages (if any)
on, the Senior Notes will be payable at the office or agency of the Issuers
maintained for such purpose or, at the option of the Issuers, payment of
interest and Liquidated Damages (if any) may be made by check mailed to the
Holders of the Senior Notes at their respective addresses set forth in the
register of Holders of the Senior Notes; provided that if the Holder of any
Senior Notes has given wire transfer instructions to the Company, the Issuers
will be

<PAGE>   91
 
required to make all payments with respect to such Senior Notes by wire transfer
of immediately available funds to the account specified by such Holder. Until
otherwise designated by the Issuers, the Issuers' office or agency will be the
office of the Trustee maintained for such purpose. The Exchange Notes will be
issued in denominations of $1,000 and integral multiples thereof.
 
OPTIONAL REDEMPTION
 
     The Senior Notes will not be redeemable prior to August 15, 2001.
Thereafter, the Senior Notes will be subject to redemption at the option of the
Issuers, in whole or in part, upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount)
set forth below, plus accrued and unpaid interest (including Revenue
Participation Interest, if any) and Liquidated Damages (if any) thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning
on August 15 of the years indicated below:

     Notwithstanding the foregoing, prior to August 15, 1999, the Issuers may
redeem outstanding Senior Notes with the net proceeds of one or more sales of
Capital Stock (other than Disqualified Stock) of OCC, Teleglobe Mobile or the
Company to one or more Persons at a redemption price equal to 115% of the
principal amount thereof, plus accrued and unpaid interest (including Revenue
Participation Interest, if any) and Liquidated Damages (if any) thereon to the
redemption date; provided, however, that: (i) not less than $127.5 million
aggregate principal amount of Senior Notes remain outstanding immediately after
any such redemption; and (ii) such redemption shall occur within 30 days after
the date of closing of such sale of Capital Stock.
 
MANDATORY REDEMPTION
 
     The Issuers will not be required to make mandatory redemption or sinking
fund payments with respect to the Senior Notes. However, as described below, the
Issuers may be obligated, under certain circumstances, to make an offer to
purchase: (i) all outstanding Senior Notes at a redemption price of 101% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages (if any) to the date of purchase, upon a Change of Control; and (ii)
outstanding Senior Notes with a portion of the Net Proceeds of Asset Sales at a
redemption price of 100% of the principal amount thereof, plus accrued and
unpaid interest (including Revenue Participation Interest, if any) and
Liquidated Damages (if any) to the date of purchase. See "-- Repurchase at the
Option of Holders -- Change of Control" and "-- Limitation on Sales of Assets
and Subsidiary Interests."
 
SECURITY
 
     The Indenture provided that upon the closing of the Old Notes Offering, the
Company purchase and pledge to the Collateral Agent 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
certified public accountants selected by the Company, to provide for payment in
full of the first four scheduled interest payments due on the Senior Notes. The
Company used approximately $44.8 million of the net proceeds of the Old Notes
Offering to acquire the Pledged Securities. The Pledged Securities are pledged
by the Company to the Collateral Agent for the benefit of the Holders of Senior
Notes pursuant to the Pledge Agreement and will be held by the Collateral Agent
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 Collateral Agent 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 Collateral Agent to release from the Pledge Account proceeds
sufficient to pay interest then
 
                                       85
<PAGE>   92
 
due. In the event that the Company exercises the former option, the Company may
thereafter direct the Collateral Agent to release to the Company from the Pledge
Account proceeds or Pledged Securities in like amount.
 
     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 certified public accountants selected by the Company, to
provide for payment in full of the first four 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 fourth scheduled interest payment)
the Collateral Agent will be permitted to release to the Company at the
Company's request any such excess amount. The Senior Notes are secured by a
first priority security interest in the Pledged Securities and in the Pledge
Account and, accordingly, the Pledged Securities and the Pledge Account also
secure repayment of the principal amount of the Senior Notes to the extent of
such security.
 
     Under the terms of the Pledge Agreement, assuming that the Company makes
the first four scheduled interest payments on the Senior Notes in a timely
manner, all the Pledged Securities will be released from the Pledge Account.
 
GUARANTEES
 
     The obligations of the Issuers under the Senior Notes are guaranteed,
jointly and severally, by OCC, Teleglobe Mobile, ORBCOMM USA and ORBCOMM
International and such other persons that become Subsidiary Guarantors after the
Issue Date (as described below) and each of their respective successors. The
guarantee issued by each Guarantor ranks senior in right and priority of payment
to all other indebtedness of such Guarantor that is expressly subordinated to
the guarantee of the Senior Notes and ranks pari passu in right and priority of
payment with all other indebtedness of such Guarantor that is not expressly so
subordinated to such guarantee, except to the extent of any collateral securing
such other indebtedness.
 
     The Indenture contains provisions the intent of which is to provide that
the obligations of each Subsidiary Guarantor will be limited to the maximum
amount that will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any
collections from, rights to receive contribution from, or payments made by or on
behalf of any other Subsidiary Guarantor in respect of the obligations of such
other Subsidiary Guarantor under its Guarantee or pursuant to its contribution
obligations under the Indenture, result in the obligations of such Subsidiary
Guarantor under its Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under any applicable federal, state or foreign law. Each
Subsidiary Guarantor that makes a payment or distribution under a Guarantee
shall be entitled to contribution from each other Subsidiary Guarantor so long
as the exercise of such right does not impair the rights of the Holders of the
Senior Notes under the Guarantees. See "Risk Factors -- Fraudulent Conveyance
Considerations -- Subsidiary Guarantees."
 
     The Indenture provides that in the event of: (i) a sale or other
disposition of all or substantially all of the assets of any Subsidiary
Guarantor or the sale of a Subsidiary Guarantor, by way of merger, consolidation
or otherwise; (ii) a Subsidiary Guarantor becoming an Unrestricted Subsidiary
pursuant to the terms of the Indenture; or (iii) a sale or other disposition of
all of the Capital Stock of any Subsidiary Guarantor, then such Subsidiary
Guarantor or the corporation acquiring the property, as applicable, shall be
released and relieved of any obligations under its guarantee, provided that the
Company complies with the provisions of the covenant entitled "Limitation on
Sales of Assets and Subsidiary Interests."
 
     The Indenture provides that in the event: (i) the Credit Parties or any
other Guarantor shall transfer or cause to be transferred, in one transaction or
a series of related transactions, any assets, businesses, divisions or other
property having a book value determined in accordance with GAAP or a Fair Market
Value which, when aggregated with all Investments described in clause (vi) of
the definition of "Permitted Investment," would be in excess of the greater of
(x) $5 million or (y) 5% of the System Consolidated Net Worth as of the date of
transfer to any Subsidiary that is not a Subsidiary Guarantor; (ii) the Credit
Parties or any other Guarantor shall acquire another Subsidiary with assets
having either a book value determined in accordance
 
                                       86
<PAGE>   93
 
with GAAP or a Fair Market Value which, when aggregated with all Investments
described in clause (vi) of the definition of "Permitted Investment," would be
in excess of the greater of (x) $5 million or (y) 5% of the System Consolidated
Net Worth as of the date on which any such acquisition is consummated; or (iii)
at any time after the Issue Date, Restricted Subsidiaries of the Credit Parties
and any Guarantors which are not Subsidiary Guarantors shall, in the aggregate,
hold, own or otherwise control assets, businesses, divisions or property having
either a book value determined in accordance with GAAP or a Fair Market Value
which, when aggregated with all Investments described in clause (vi) of the
definition of "Permitted Investment," would be in excess of the greater of (x)
$5 million or (y) 5% of the System Consolidated Net Worth as of any date, then,
in each such case, the Credit Parties or the Guarantor shall cause such
Restricted Subsidiary or any number of Restricted Subsidiaries, as the case may
be, to execute a supplemental indenture for purposes of guaranteeing the
Issuers' obligations under the Indenture and the Senior Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
  Change of Control
 
     Upon the occurrence of a Change of Control, each Holder of Senior Notes has
the right to require the Issuers to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's Senior Notes pursuant to the
offer described below (the "Change of Control Offer") at an offer price in cash
equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid
interest (including Revenue Participation Interest, if any) and Liquidated
Damages (if any) thereon to the date of purchase (the "Change of Control
Payment"). Within ten days following any Change of Control, the Issuers will
mail a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offering to repurchase Senior Notes
pursuant to the procedures required by the Indenture and described in such
notice. The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Senior Notes as a result of a Change of Control.
 
     On the Change of Control Payment date, the Issuers will, to the extent
lawful:
 
          (i) accept for payment all Senior Notes or portions thereof properly
     tendered pursuant to the Change of Control Offer;
 
          (ii) deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Senior Notes or portions thereof so
     tendered; and
 
          (iii) deliver or cause to be delivered to the Trustee the Senior Notes
     so accepted together with an Officers' Certificate stating the aggregate
     principal amount of Senior Notes or portions thereof being purchased by the
     Issuers.
 
     The Paying Agent will promptly mail to each Holder of Senior Notes so
tendered the Change of Control Payment for such Senior Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Senior Note equal in principal amount to any unpurchased
portion of the Senior Note surrendered; provided that each such new Note will be
in a principal amount of $1,000 or an integral multiple thereof. The Issuers
will publicly announce the results of the Change of Control Offer on or as soon
as practicable after the Change of Control Payment date.
 
     The Issuers will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the time and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all Senior Notes validly tendered and not withdrawn under such Change
of Control Offer.
 
     Subject to the limitations discussed below, the Issuers could in the future
enter into certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of Indebtedness outstanding at
such time or otherwise affect the Issuers' capital structure or credit ratings.
Due to the highly leveraged structure of the Issuers, the Issuers may not have
sufficient funds to be able to repurchase all of the Senior Notes tendered in a
 
                                       87
<PAGE>   94
 
Change of Control Offer. The failure of the Issuers to purchase any Senior Notes
tendered in a Change of Control Offer will constitute an Event of Default under
the Indenture. See "-- Events of Default and Remedies."
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of any of the Credit Parties' assets. Although there is a developing body of
case law interpreting the phrase "substantially all," there is no precise
established definition of the phrase under applicable law. Accordingly, the
ability of a Holder of Senior Notes to require the Issuers to repurchase such
Notes as a result of a sale, lease, transfer, conveyance or other disposition of
less than all of the assets of the Issuers to another Person may be uncertain.
 
  Limitation on Sales of Assets and Subsidiary Interests
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, engage in an Asset Sale unless:
 
          (i) the Credit Party or such Restricted Subsidiary, as the case may
     be, engaging in such Asset Sale receives consideration at the time of such
     Asset Sale at least equal to the Fair Market Value of the assets sold or
     otherwise disposed of; and
 
          (ii) the aggregate Fair Market Value of all non-Cash Consideration
     received therefor by such Credit Party or Restricted Subsidiary, as the
     case may be, when aggregated with the Fair Market Value of all other
     non-Cash Consideration received by the Credit Parties and their Restricted
     Subsidiaries from all other Asset Sales since the Issue Date that has not
     yet been converted into cash or Cash Equivalents (in either case, in U.S.
     dollars or freely convertible into U.S. dollars), does not exceed the sum
     of (without duplication) 5% of the aggregate Consolidated Tangible Net
     Assets of all of the Credit Parties at the time of such Asset Sale;
     provided, however, that any notes or similar obligations received by any of
     the Credit Parties or such Restricted Subsidiaries from such transferees
     that are immediately converted by the Credit Parties or such Restricted
     Subsidiaries into cash, shall be deemed to be cash (to the extent of the
     net cash received) for purposes of this clause (ii).
 
     Within 270 days after the receipt of any Net Proceeds, the Issuers may
apply such Net Proceeds to: (i) repay, and thereby permanently reduce the
commitments or amounts available to be reborrowed under the Bank Credit Facility
pursuant to clause (vii) of the covenant entitled "Incurrence of Indebtedness or
Issuance of Restricted Subsidiary Disqualified Stock" or to repay the Senior
Notes or the MetLife Note; or (ii) an investment in Related Assets or a Related
Business. Pending the final application of any such Net Proceeds, the Issuers
may temporarily invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds that are not applied or invested as provided in
the first sentence of this paragraph will be deemed to constitute "Excess
Proceeds." When the aggregate cumulative amount of Excess Proceeds exceeds $5
million, the Issuers will be required to make an offer to all Holders of Senior
Notes (an "Asset Sale Offer") to purchase the maximum principal amount of Senior
Notes that may be purchased out of the Excess Proceeds (and not solely the
amount in excess of $5 million), at an offer price in cash in an amount equal to
100% of the principal amount thereof, plus accrued and unpaid interest
(including Revenue Participation Interest, if any) and Liquidated Damages (if
any) thereon to the date of purchase, in accordance with the procedures set
forth in the Indenture. To the extent that the aggregate amount of Senior Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Issuers may use any remaining Excess Proceeds for general business purposes. If
the aggregate amount of Senior Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Trustee will select the Senior Notes to be
purchased on a pro rata basis. Upon completion of such offer to purchase, the
amount of Excess Proceeds will be reset at zero. The Asset Sale Offer shall
remain open for a period of 20 business days or such longer period as may be
required by law.
 
     The foregoing provisions do not apply to the sale, lease, conveyance or
other disposition of all or substantially all of the assets of either of the
Issuers, OCC or Teleglobe Mobile, which is governed by the provisions of the
Indenture described below in "-- Merger, Consolidation or Sale of Assets."

<PAGE>   95
 
SELECTION AND NOTICE OF SENIOR NOTES FOR REDEMPTION OR REPURCHASE
 
     If less than all of the Senior Notes are to be redeemed or repurchased
pursuant to any purchase offer required under the Indenture at any time,
selection of Senior Notes for redemption or repurchase will be made by the
Trustee in compliance with the requirements of the principal national securities
exchange, if any, on which the Senior Notes are listed or, if the Senior Notes
are not so listed, on a pro rata basis, selected by lot or by such method as the
Trustee shall deem fair and appropriate; provided that no Senior Note with a
principal amount of $1,000 or less shall be redeemed or repurchased in part.
 
     Notices of redemption or repurchase shall be mailed by first class mail at
least 30 but not more than 60 days before the redemption or repurchase date to
each Holder of Senior Notes to be redeemed or repurchased at its registered
address. If any Senior Note is to be redeemed or repurchased in part only, the
notice that relates to such Senior Note shall state the portion of the principal
amount thereof to be redeemed or repurchased. A new Senior Note in principal
amount equal to the unredeemed or unrepurchased portion will be issued in the
name of the Holder thereof upon cancellation of the original Senior Note. On and
after the redemption or repurchase date, interest will cease to accrue on the
Senior Notes or portions thereof called for redemption or repurchase.
 
CERTAIN COVENANTS
 
  Restricted Payments
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, directly or indirectly:
 
          (i) declare or pay any dividend or make any distribution on account of
     the Equity Interests of any Credit Party (including, without limitation,
     any payment in connection with any merger or consolidation involving the
     Credit Parties or any of their Restricted Subsidiaries), other than
     dividends or distributions payable (a) in Equity Interests (other than
     Disqualified Stock) of the Credit Parties or any of their Restricted
     Subsidiaries or (b) to any Credit Party or to any Restricted Subsidiary of
     a Credit Party;
 
          (ii) purchase, redeem, defease, retire or otherwise acquire or return
     for value any Equity Interests of any Credit Party, other than any such
     Equity Interests owned by a Credit Party or any Wholly Owned Restricted
     Subsidiary of a Credit Party;
 
          (iii) make any principal payment on (including at maturity) or
     purchase, redeem, defease or otherwise acquire or retire for value any
     Indebtedness that is subordinated (whether pursuant to its terms, by
     operation of law, structurally or otherwise) to the Senior Notes; or
 
          (iv) make any Restricted Investment
 
(all such payments and other actions set forth in clauses (i) through (iv) above
being collectively referred to as "Restricted Payments"), unless, at the time of
and after giving effect to such Restricted Payment:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof;
 
          (b) the Issuers would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the immediately preceding fiscal quarter,
     have been permitted to incur at least $1.00 of additional Indebtedness
     pursuant to the Indebtedness to Cash Flow Ratio test set forth in the first
     paragraph of the covenant entitled "Incurrence of Indebtedness or Issuance
     of Restricted Subsidiary Disqualified Stock"; and
 
          (c) such Restricted Payment, together with the aggregate of all other
     Restricted Payments made by the Credit Parties and their Restricted
     Subsidiaries after the Issue Date (excluding Restricted Payments permitted
     by clauses (iii) through (v) of the next succeeding paragraph), is less
     than the sum of:
 
          (1) the sum of (without duplication) 50% of the Consolidated Net
     Income of each of the Credit Parties after elimination of any intercompany
     items and in each case for the period (taken as one
 
                                       89
<PAGE>   96
 
     accounting period) from the beginning of the first fiscal quarter
     commencing after the Issue Date to the end of the Company's most recently
     ended fiscal quarter for which financial statements are available at the
     time of such Restricted Payment (or, if such aggregate Consolidated Net
     Income for such period is a deficit, less 100% of such deficit), plus
 
          (2) 100% of the aggregate net cash proceeds received by the Credit
     Parties from the issue or sale since the Issue Date of Equity Interests of
     any Credit Party or of debt securities of any Credit Party that have been
     converted into such Equity Interests (other than (A) Equity Interests (or
     convertible debt securities) sold to a Subsidiary of any Credit Party, (B)
     Disqualified Stock or debt securities that have been converted into
     Disqualified Stock, (C) Disqualified Capital Contributions and (D) equity
     capital contributions described in clause (vii) of the definition of
     "Permitted Investment"), plus
 
          (3) to the extent that any Restricted Investment that was made after
     the Issue Date is sold for cash or otherwise liquidated or repaid for cash,
     the lesser of (A) the cash return of capital with respect to such
     Restricted Investment (less the cost of disposition, if any) and (B) the
     initial amount of such Restricted Investment.
 
     The foregoing provisions do not prohibit:
 
          (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of the Indenture;
 
          (ii) the redemption, repurchase, retirement or other acquisition of
     any Equity Interests of any Credit Party in exchange for, or out of the
     proceeds of, the substantially concurrent sale (other than to a Subsidiary
     of any Credit Party) of other Equity Interests of any Credit Party (other
     than any Disqualified Stock and Disqualified Capital Contributions);
     provided that the amount of any such net cash proceeds that are utilized
     for any such redemption, repurchase, retirement or other acquisition shall
     be excluded from clause (2) of the preceding paragraph;
 
          (iii) the repayment, defeasance, redemption or repurchase of
     Intercompany Indebtedness (as defined in clause (v) of the covenant
     entitled "Incurrence of Indebtedness or Issuance of Restricted Subsidiary
     Disqualified Stock") or Indebtedness with the net cash proceeds from an
     incurrence of Permitted Refinancing Indebtedness or the substantially
     concurrent sale (other than to a Subsidiary of any Credit Party) of Equity
     Interests of any Credit Party (other than Disqualified Stock and
     Disqualified Capital Contributions); provided that the amount of any such
     net cash proceeds that are utilized for any such redemption, repurchase,
     retirement or other acquisition shall be excluded from clause (2) of the
     preceding paragraph;
 
          (iv) the payment of cash dividends on preferred partnership interests
     of any Credit Party that is a partnership if, at the time such preferred
     partnership interests were issued, such Credit Party delivered to the
     Trustee an Officers' Certificate certifying that (a) the aggregate
     liquidation preference of the preferred partnership interest so issued does
     not exceed the aggregate amount of Indebtedness that the Company is then
     permitted to incur pursuant to clauses (vii) and (x) of the exceptions to
     the covenant entitled "Incurrence of Indebtedness or Issuance of Restricted
     Subsidiary Disqualified Stock" and (b) the Company is electing to reduce
     permanently the amount of Indebtedness that any Person is permitted to
     incur pursuant to such clauses (vii) and (x) by the amount of such
     aggregate liquidation preference;
 
          (v) the purchase, redemption or retirement by OCC of shares of its
     common stock held by an employee or former employee of one of the Credit
     Parties or their Subsidiaries or Orbital issued under the OCC Stock Option
     Plan pursuant to the terms of such OCC Stock Option Plan; provided that (1)
     the aggregate number of shares of common stock purchased, redeemed or
     retired from and after the Issue Date does not exceed 900,000 shares, and
     (2) the amount of any such payments in any fiscal year does not exceed
     $1,000,000; and provided, further, that the limitations set forth in
     clauses (1) and (2) of the foregoing proviso do not apply to the purchase,
     redemption or retirement of shares of common stock with funds or other
     property (including common stock of Orbital) contributed by partners of
     OCC, Teleglobe Mobile or the Company (other than Disqualified Capital
     Contributions) or amounts paid by any of the
 
                                       90
<PAGE>   97
 
     Credit Parties for which any of the Credit Parties receives concurrent
     reimbursement from any other Person (other than the Credit Parties or their
     Subsidiaries);
 
          (vi) payments and/or distributions (1) by OCC to its shareholders
     pursuant to the Tax Sharing Agreement and (2) by Teleglobe Mobile to its
     partners to the extent necessary to pay income tax liabilities of such
     partners (determined on a hypothetical basis using the highest marginal
     income tax rate applicable to such partners at the time of such payment)
     arising from income of Teleglobe Mobile allocable to such partners and
     attributable to Teleglobe Mobile's investment in the Company, but only to
     the extent Teleglobe Mobile is not subject to income tax on such income;
     and
 
          (vii) distributions made to Orbital and Teleglobe of unused portions
     of any amount drawn under the Partners' Insurance Contingent Commitment (as
     described under "-- Maintenance of Insurance") and Partners' Contingent
     Commitment (as described under "-- Partners' Contingent Commitment").
 
     A Credit Party may designate any Restricted Subsidiary of such Credit Party
to be an Unrestricted Subsidiary if such designation would not cause a Default
and, at the time of and after giving effect to such designation, the Issuers
could incur $1.00 of additional Indebtedness under the applicable provisions of
the first paragraph of the covenant entitled "Incurrence of Indebtedness or
Issuance of Restricted Subsidiary Disqualified Stock"; provided that in no event
shall all or any portion of the material assets or properties (other than cash)
owned by the Credit Parties on the Issue Date be transferred to or held by an
Unrestricted Subsidiary of any of the Credit Parties; and provided, further,
that such ability to incur $1.00 of additional Indebtedness shall not be
required in the case of any newly created Unrestricted Subsidiary funded solely
with an Investment described in clause (vii) of the definition of "Permitted
Investment." For purposes of making such determination, all outstanding
Investments by the Credit Parties and their Restricted Subsidiaries (except to
the extent repaid in cash and except for Investments described in clause (vii)
of the definition of "Permitted Investment") in the Subsidiary so designated
will be deemed to be Restricted Payments at the time of such designation and
will reduce the amount available for Restricted Payments under the first
paragraph of this covenant. All such outstanding Investments will be deemed to
constitute Investments in an amount equal to the greatest of:
 
           (i) the net book value of such Investments at the time of such
     designation;
 
           (ii) the Fair Market Value of such Investments at the time of such
     designation; and
 
          (iii) the original Fair Market Value of such Investments at the time
     they were made.
 
     Such designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.
 
     The amount of all Restricted Payments, if not made in cash, shall be the
Fair Market Value on the date of the Restricted Payment of the asset(s) proposed
to be transferred by the Credit Party or such Restricted Subsidiary, as the case
may be, pursuant to the Restricted Payment. Not later than the date of making
any Restricted Payment, the Issuers shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this covenant were computed,
which calculations may be based upon the latest available financial statements
of the Company, ORBCOMM USA and ORBCOMM International.
 
  Incurrence of Indebtedness or Issuance of Restricted Subsidiary Disqualified
Stock
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, directly or indirectly, create,
incur, issue, assume, guaranty or otherwise become directly or indirectly
liable, contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt) or any Disqualified Stock of any
Restricted Subsidiary; provided, however, that the Issuers, ORBCOMM USA or
ORBCOMM International or any of their Restricted Subsidiaries may incur
Indebtedness (including Acquired Debt) if, after giving pro forma effect to the
incurrence of such Indebtedness and the use of proceeds thereof, the aggregate
Indebtedness to Cash Flow Ratio of the Credit Parties does not exceed 4.0 to 1.
For purposes of the foregoing, the total amount of funds available under any
 
                                       91
<PAGE>   98
 
Bank Credit Facility will be deemed to have been incurred at the time that the
Company entered into the instruments or agreements providing therefor.
 
     The foregoing provisions do not apply to:
 
          (i) the incurrence by the Issuers of Indebtedness represented by the
     Notes and the Indenture or the incurrence by the Guarantors of Indebtedness
     represented by the Guarantees;
 
          (ii) Existing Indebtedness;
 
          (iii) Indebtedness under (A) Hedging Obligations, provided that (1)
     the notional principal amount of any interest rate protection agreement
     does not significantly exceed the principal amount of the Indebtedness to
     which such interest rate protection agreement relates and (2) any
     agreements related to fluctuations in currency rates do not increase the
     outstanding Indebtedness other than as result of fluctuations in foreign
     currency exchange rates, and (B) performance, surety and workers'
     compensation bonds or other obligations of a like nature incurred in the
     ordinary course of business;
 
          (iv) the incurrence by any Unrestricted Subsidiary of any of the
     Credit Parties of Non-Recourse Debt; provided that if any such Indebtedness
     ceases to be Non-Recourse Debt of an Unrestricted Subsidiary such event
     shall be deemed to constitute an incurrence of Indebtedness by a Restricted
     Subsidiary;
 
          (v) Indebtedness of any of the Credit Parties or any of their
     Restricted Subsidiaries owed to and held by any of the Credit Parties or
     any of their Wholly Owned Restricted Subsidiaries or a Guarantor's
     obligations under a guarantee thereof, as the case may be (the Indebtedness
     incurred pursuant to this clause (v) being hereafter referred to as
     "Intercompany Indebtedness"); provided that an incurrence of Indebtedness
     shall be deemed to have occurred upon (i) any sale or other disposition of
     Intercompany Indebtedness to a Person other than any of the Credit Parties
     or any of their Restricted Subsidiaries, (ii) any sale or other disposition
     of Equity Interests of any of the Credit Parties' Restricted Subsidiaries
     which holds Intercompany Indebtedness such that such Restricted Subsidiary
     ceases to be a Restricted Subsidiary after such sale or other disposition
     or (iii) designation of a Restricted Subsidiary as an Unrestricted
     Subsidiary;
 
          (vi) Non-Recourse Debt to finance purchase money obligations;
 
          (vii) the incurrence by any of the Issuers, ORBCOMM USA or ORBCOMM
     International or any of their Restricted Subsidiaries (or by OCC or
     Teleglobe Mobile as a guarantor of such Indebtedness) of Indebtedness under
     a Bank Credit Facility, provided that the aggregate principal amount at any
     time outstanding under this clause (vii) does not exceed $35 million, less
     the aggregate liquidation preference of any preferred partnership interests
     issued in reliance on clause (iv) of the exceptions to the covenant
     entitled "Restricted Payments" and less the aggregate principal amount of
     Indebtedness under this clause (vii) which is refinanced under clause
     (viii) below;
 
          (viii) Indebtedness of any of the Issuers, ORBCOMM USA or ORBCOMM
     International or any of their Restricted Subsidiaries ("Permitted
     Refinancing Indebtedness") incurred to refinance, replace or refund
     Indebtedness ("Refinanced Indebtedness") incurred pursuant to the
     Indebtedness to Cash Flow Ratio test set forth in the first paragraph of
     this covenant or pursuant to clauses (i), (ii), (vii) or (x) of this
     covenant; provided that:
 
             (a) the aggregate principal amount of such Permitted Refinancing
        Indebtedness does not exceed the aggregate principal amount of the
        Refinanced Indebtedness (including accrued and unpaid interest thereon);
 
             (b) such Permitted Refinancing Indebtedness shall have a final
        maturity equal to or later than, and a Weighted Average Life to Maturity
        equal to or greater than, the final maturity and Weighted Average Life
        to Maturity of the Refinanced Indebtedness, respectively;
 
             (c) such Permitted Refinancing Indebtedness shall rank no higher
        relative to the Senior Notes than the Refinanced Indebtedness and in no
        event may any Indebtedness of any of the Issuers,
 
                                       92
<PAGE>   99
 
        ORBCOMM USA or ORBCOMM International or any of their Restricted
        Subsidiaries be refinanced with Indebtedness of any Restricted
        Subsidiary under this clause (viii) (except to the extent that any such
        Restricted Subsidiary was, prior to such refinancing, a guarantor of
        such Refinanced Indebtedness); and
 
             (d) in no event shall any Permitted Refinancing Indebtedness
        refinance, replace or refund the MetLife Note unless the Liens securing
        such MetLife Note are released in full;
 
          (ix) the incurrence by any of the Issuers, ORBCOMM USA or ORBCOMM
     International or any of their Restricted Subsidiaries of Capital Lease
     Obligations in an aggregate amount for all such Persons not to exceed $5
     million at any one time outstanding;
 
          (x) the incurrence by any of the Issuers, ORBCOMM USA or ORBCOMM
     International or any of their Restricted Subsidiaries of Indebtedness to
     finance the acquisition, construction or development, either alone or
     together with third Persons, of domestic and/or international gateways,
     related ground systems and associated costs and expenses in an aggregate
     amount not to exceed $10 million at any one time outstanding for all such
     Persons less the aggregate liquidation preference of any preferred
     partnership interests issued in reliance on clause (iv) of the exceptions
     to the covenant entitled "Restricted Payments" and less the aggregate
     principal amount of Indebtedness under this clause (x) which is refinanced
     under clause (viii) above;
 
          (xi) the incurrence by OCC and/or Teleglobe Mobile of Indebtedness in
     an aggregate amount (for OCC and Teleglobe Mobile, taken together as a
     whole) at any one time outstanding not to exceed $10 million; provided that
     such Indebtedness could then otherwise have been incurred by the Issuers,
     ORBCOMM USA or ORBCOMM International under the Indebtedness to Cash Flow
     Ratio test set forth under the first paragraph of this covenant; and
 
          (xii) the incurrence of Indebtedness under the Partners' Contingent
     Commitment pursuant to the "Maintenance of Insurance Covenant."

incur, assume or suffer to exist any Lien on any asset now owned or hereafter
acquired, or any income or profits therefrom, or assign or convey any right to
receive income therefrom, except Permitted Liens.
 
  Dividend and Other Payment Restrictions Affecting Subsidiaries
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, directly or indirectly, create

restriction on the ability of any Restricted Subsidiary to:
 
          (i) pay dividends or make any other distributions to any Credit Party
     or any of their Restricted Subsidiaries on its Capital Stock or with
     respect to any other interest or participation in, or measured by, its
     profits;
 
          (ii) pay any Indebtedness owed to any Credit Party or any of their
     Restricted Subsidiaries;

except for such encumbrances or restrictions existing under or by reason of:
 
             (a) the Indenture, the Pledge Agreement, the Notes and the
        Guarantees;
 
             (b) Existing Indebtedness;
 
                                       93

             (d) any instrument governing Indebtedness or Capital Stock of a
        Person acquired by any of the Credit Parties or any of their Restricted
        Subsidiaries as in effect at the time of such acquisition (except to the
        extent such Indebtedness was incurred in connection with or in
        contemplation of such acquisition), which encumbrance or restriction is
        not applicable to any Person, or the properties or assets of any Person,
        other than the Person, or the property or assets of the Person, so
        acquired;
 
             (e) customary non-assignment provisions in leases or other
        agreements entered into in the ordinary course of business;

        the agreements governing the Refinanced Indebtedness;
 
             (h) any instrument governing Indebtedness of a Subsidiary
        Guarantor, provided such Indebtedness is incurred in accordance with the
        Indenture; or
 
             (i) in the case of clauses (a), (b), (d), (e), (f), (g) and (h)
        above, any amendments, modifications, restatements, renewals, increases,
        supplements, modifications, restatements or refinancings thereof,
        provided that such amendments, modifications, restatements or
        refinancings are not materially more restrictive with respect to such
        dividend and other payment restrictions than those contained in such
        instruments as in effect on the date of their incurrence.
 
  Merger, Consolidation or Sale of Assets
 
     The Indenture provides that neither the Credit Parties nor any Guarantor
(to the extent not permitted by the sale provisions under "-- Guarantees" above)
may consolidate or merge with or into (whether or not any such Credit Party or
such Guarantor, as the case may be, is the surviving Person), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets in one or more related transactions to, another Person
(other than any consolidation or merger of a Credit Party or a Guarantor with or

          (i) the Credit Party or such Guarantor, as the case may be, is the
     surviving Person or the Person formed by or surviving any such

          (ii) the Person formed by or surviving any such consolidation or
     merger (if other than the Credit Party or such Guarantor, as the case may
     be) or the entity or Person to which such sale, assignment, transfer,
     lease, conveyance or other disposition shall have been made assumes all the
     obligations of the Credit Party or such Guarantor, as the case may be,
     under the Notes, the Indenture, the Pledge Agreement and the Guarantees

     shall have been made will have Consolidated Net Worth immediately after the
     transaction equal to or greater than the Consolidated Net Worth of such
     Credit Party or such Guarantor immediately preceding the transaction; and
 
                                       94
<PAGE>   101
 
          (v) the Issuers will, at the time of such transaction and after giving
     pro forma effect thereto as if such transaction had occurred at the
     beginning of the immediately preceding fiscal quarter, be permitted to
     incur at least $1.00 of additional Indebtedness pursuant to the
     Indebtedness to Cash Flow Ratio test set forth in the first paragraph of
     the covenant entitled "Incurrence of Indebtedness or Issuance of Restricted
     Subsidiary Disqualified Stock."
 
  Transactions with Affiliates
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, sell, lease transfer or
otherwise dispose of any of their properties or assets to, or purchase any
property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless:
 
          (i) such Affiliate Transaction is on terms that are no less favorable
     to the Credit Party or such Restricted Subsidiary than those that would
     have been obtained in a comparable transaction by the Credit Party or such
     Restricted Subsidiary with an unrelated Person;
 
          (ii) such Credit Party delivers to the Trustee:
 
             (a) with respect to any Affiliate Transaction involving aggregate
        consideration in excess of $1 million, an Officers' Certificate
        certifying that such Affiliate Transaction complies with clause (i)

        in the ordinary course of business, and transactions pursuant to a
        Service License Agreement for Malaysia or a region including Malaysia

        the Company;

        2.2, 2.6, 2.8, 2.9 or 2.10 of the Procurement Agreement (including
        entering into time and materials agreements thereunder pursuant to the
        terms of the Procurement Agreement) and amendments, supplements or other
        modifications to the Procurement Agreement required to effectuate the
        exercise of such options;
 
                                       95
<PAGE>   102
 
             (7) amendments, supplements or other modifications effecting design
        or other technical specifications changes to the Procurement Agreement
        that do not involve the payment of cash by any of the Credit Parties or
        any of their Restricted Subsidiaries in connection therewith; provided
        that any such amendment, supplement or modification shall have been
        approved by the unanimous consent of all the General Partners of the
        Company;
 
             (8) the sale of securities (other than common Equity Interests) of

           sold to such Affiliate have been or are being sold substantially
           simultaneously to Persons that are not Affiliates of any of the
           Credit Parties;
 
                (B) the price per security paid by such Affiliate is no less
           than the price paid by such non-Affiliates; and
 
                (C) none of the Credit Parties shall have entered into any other
           arrangement with such non-Affiliates to induce such non-Affiliates to
           purchase such securities; and
 
             (9) the procurement of a launch vehicle from an Affiliate of the
        Company, if required to launch the "ground spare" or replacement
        satellites, provided such procurement is on terms substantially similar
        to those contained in the Procurement Agreement.
 
  Maintenance of Insurance
 
     The Indenture provides that the Issuers shall maintain in full force and
effect:
 
          (i) on or prior to the date on which at least 26 satellites have been
     launched and tested and, together with the related ground systems, are
     reasonably believed by the Company to be ready for commercial operation as
     part of the ORBCOMM System, at the time of the launch of each such
     satellite, launch insurance in an amount sufficient to provide for the
     procurement of a launch vehicle in the event of a launch failure;
 
          (ii) at all times following the date a satellite has been successfully
     launched and deployed and is placed in commercial service, in-orbit
     insurance with respect to such satellite representing the value of such
     failed satellite (taking into account the foregone useful life of such
     satellite) and the pro rata cost of a launch vehicle, payable in the event
     that such satellite ceases to be used for commercial revenue producing
     service (provided that such insurance may contain customary provisions for
     deductible payments and minimum thresholds for satellite failure); and
 
          (iii) in the event (a) the Company is required to use four or more of
     the Company's "ground spare" satellites available under the Procurement
     Agreement, or (b) the Company loses four or more satellites within any
     plane of eight satellites, or six or more satellites within any two planes
     of eight satellites, as a result of a launch failure or in-orbit failure
     prior to the placement of satellites into commercial service, for the time
     periods specified in clause (i) above, insurance sufficient to provide for
     the construction and launch of replacement satellites of equivalent
     capacity and functionality payable in the event of a loss of four or more
     satellites within any plane of eight satellites, or six or more satellites
     within any two planes of eight satellites, as a result of a launch failure
     or in-orbit failure prior to placement of such satellites into commercial
     service.
 
     Notwithstanding the foregoing, the Company is not obligated to obtain
launch or in-orbit insurance with respect to the two satellites currently
operational and the two satellites currently planned to be launched on a
secondary basis on a Taurus launch vehicle and launch insurance with respect to
other launches of up to an aggregate of three additional satellites on a
secondary basis.
 
                                       96
<PAGE>   103
 
     The obligation of the Issuers to maintain insurance pursuant to this
covenant may be satisfied by any combination of:
 
          (i) insurance commitments obtained from any recognized insurance
     provider;
 
          (ii) insurance commitments obtained from any entity other than an
     entity referred to in clause (i) if the General Partners of the Company
     determine in good faith (evidenced by a unanimous resolution of the General
     Partners of the Company and set forth in an Officers' Certificate delivered
     to the Trustee) that such entity is creditworthy and otherwise capable of
     bearing the financial risk of providing such insurance and making payments
     in respect of any claims on a timely basis; and
 
          (iii) unrestricted cash segregated and maintained by the Company in a
     segregated account established with an Eligible Institution (the "Insurance
     Account") solely for disbursement in accordance with the terms of this
     covenant ("Cash Insurance"), and to be held in trust for the sole and
     express benefit of the Holders of the Senior Notes.
 
     Within 30 days following any date on which the Issuers are required to
obtain insurance pursuant to the Indenture, the Company will deliver to the
Trustee an insurance certificate certifying the amount of insurance then
carried, and in full force and effect, and an Officers' Certificate stating that
such insurance, together with any other insurance or Cash Insurance maintained
by the Issuers, complies with the Indenture. In addition, the Issuers will cause
to be delivered to the Trustee no less than once each year an insurance
certificate setting forth the amount of insurance then carried, which insurance
certificate shall entitle the Trustee to:
 
           (i) notice of any claim under any such insurance policy; and
 
          (ii) at least 30 days' notice from the provider of such insurance
     prior to the cancellation of any such insurance.
 
     In the event that the Issuers maintain any Cash Insurance in satisfaction
of any part of their obligation to maintain insurance pursuant to this covenant,
the Issuers shall deliver, in lieu of any insurance certificate otherwise
required by this covenant, an Officers' Certificate to the Trustee certifying
the amount of such Cash Insurance.
 
     In the event that the Issuers receive any proceeds of any insurance that
they are required to maintain pursuant to this covenant, the Issuers shall
promptly deposit such proceeds into an escrow account established with an
Eligible Institution for such purpose. If the Issuers maintain any Cash
Insurance in satisfaction of any part of their obligation to maintain insurance
pursuant to this covenant, the Issuers shall transfer the cash maintained in the
Insurance Account to such escrow account upon the occurrence of the event (e.g.,
a launch failure) that would have entitled the Issuers to the payment of
insurance had the Issuers purchased insurance from a recognized insurance
provider. The Company may use monies on deposit in such escrow account for the
design, development, construction, procurement, launch and insurance of
replacement satellites if: (i) the Company delivers to the Trustee a certificate
of the Company's President certifying that such replacement satellites are of
comparable or superior technological capability as compared with the satellites
being replaced, (ii) within 30 days following the receipt of such insurance
proceeds, the Company delivers to the Trustee an Officers' Certificate
certifying that (A) such replacement satellites are scheduled to be launched
within 18 months following delivery from the escrow account of such insurance
proceeds; and (B) the Company will have sufficient funds to service the
Company's projected debt service requirements until the scheduled launch of such
replacement satellite and to develop, construct, launch and insure such
replacement satellite.
 
     In the event (an "Insurance Contingency Event") that (i) four or more
satellites within any plane of eight satellites, or six or more satellites
within any two planes of satellites, suffer an in-orbit failure prior to such
satellites being placed in commercial service, and, as a result thereof, the
Company is required to launch its ground spare satellites and (ii) there are not
sufficient insurance proceeds to procure a launch vehicle for the launch of such
ground spare satellites (the amount of any such insufficiency being referred to
as the "Launch Deficiency Amount"), then the Company shall be required to
draw-down on the Partners' Insurance Contingent Commitment (as defined below)
prior to any further borrowings under the Bank Credit Facility if, but only to
the extent that, the Company's existing levels of cash and cash equivalents are
less than
 
                                       97
<PAGE>   104
 
$15 million at any time after the Insurance Contingency Event through the date
the Company has 26 satellites in commercial operation (the "Full Deployment
Date"). "Partners' Insurance Contingent Commitment" shall mean a commitment by
Orbital and Teleglobe to provide in the aggregate up to the lesser of (x) $15
million less any amounts drawn under the Partners' Contingent Commitment or (y)
the Launch Deficiency Amount in capital contributions or debt financing
expressly subordinated to the Senior Notes (at then prevailing interest rates,
which subordinated debt financing shall not mature or be subject to acceleration
prior to maturity of the Senior Notes and which shall not provide for cash
interest payments prior to maturity of the Notes) from and after an Insurance
Contingency Event through the Full Deployment Date. The Company shall have the
Partners' Insurance Contingent Commitment in full force and effect from the
Issue Date through the Full Deployment Date. Notwithstanding the restrictions
contained in the covenant entitled "Restricted Payments," following the Full
Deployment Date, Teleglobe and Orbital are permitted to receive a distribution
equal to the unused portions of any amounts drawn under the Partners' Insurance
Contingent Commitment.
 
  Repayment of Existing Indebtedness
 
     The Indenture provides that the Company establish a segregated account with
a recognized financial institution and deposit into such account from the
proceeds of the Old Notes Offering an amount sufficient to pay in full when due
all remaining scheduled interest and principal payments on the MetLife Note.
Interest earned on such account shall be payable to the Company. In the event
the funds held in such segregated account exceed the amount sufficient to
provide for payment in full of the principal of and interest on the MetLife
Note, the Company is permitted to receive from such segregated account any such
excess amount. At all times that the Company is complying with the terms of this
covenant, amounts outstanding under the MetLife Note shall not constitute
"Indebtedness" under the Indenture and amounts held in such segregated account
shall not constitute assets of any Credit Party under the Indenture.
 
  Business Activities
 
     The Indenture provides that the Credit Parties will not, and will not
permit any of their Restricted Subsidiaries to, engage in any business other
than that which is related to the design, development, procurement,
installation, operation or marketing of communications systems and businesses.
The Indenture will also provide that Capital shall not own any operating assets
or other property or conduct any business other than to serve as an Issuer and
obligor with respect to the Senior Notes.
 
  Partners' Contingent Commitment
 
     In the event (a "Contingency Event") that (i) at least 20 satellites have
not been placed in commercial service by December 31, 1998 and (ii) the
Company's existing levels of cash and cash equivalents are less than $25 million
(the amount of any such shortfall at any time prior to the Initial Deployment
Date (as defined below) being referred to as the "Deficiency Amount"), then the
Company shall be required to draw-down on the Partners' Contingent Commitment
(as defined below) from time to time after the Contingency Event through the
date the Company has 20 satellites in commercial operation (the "Initial
Deployment Date"). "Partners' Contingent Commitment" shall mean a commitment by
Orbital and Teleglobe to provide in the aggregate to the Company up to the
lesser of (x) $30 million less amounts drawn under the Partners' Insurance
Contingent Commitment, (y) the Deficiency Amount or (z) the amount required to
complete deployment of such 20 satellites, in capital contributions or debt
financing expressly subordinated to the Notes (at then prevailing interest
rates, which subordinated debt financing shall not mature or be subject to
acceleration prior to maturity of the Senior Notes and which shall not provide
for cash interest payments prior to maturity of the Senior Notes) from and after
a Contingency Event through the Initial Deployment Date, and the Partners'
Contingent Commitment shall thereafter expire. The Company shall have the
Partners' Contingent Commitment in full force and effect from the Issue Date
through the Initial Deployment Date. Notwithstanding the restrictions contained
in the covenant entitled "Restricted Payments," following the Initial Deployment
Date, Teleglobe and Orbital are permitted to receive a distribution equal to the
unused portion of any amounts drawn under the Partners' Contingent Commitment.
 
                                       98
<PAGE>   105
 
  Contingency Fund
 
     The Indenture provides that the Company establish a segregated account with
a recognized financial institution and shall deposit $13 million into such
account from the proceeds of the Old Notes Offering (the "Contingency Fund").
The Company has agreed that it will not expend monies in the Contingency Fund
unless and until it has already expended all of the remaining proceeds of the
Offering, and will only expend monies in the Contingency Fund to fund
development and deployment of the ORBCOMM System and related operating expenses.
Amounts in such segregated account comprising the Contingency Fund may be
invested by the Company in cash or Cash Equivalents in accordance with the terms
of the Indenture.
 
  Reports
 
     The Indenture provides that, whether or not required by the rules and
regulations of the Commission, so long as any Senior Notes are outstanding, the
Issuers will furnish to the Holders of Senior Notes:
 
          (i) all quarterly and annual financial information that would be
     required to be contained in a filing with the Commission on Forms 10-Q and
     10-K if the Issuers were required to file such Forms, including a
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations" that describes the financial condition and results of
     operations of the Issuers and their Restricted Subsidiaries and, with
     respect to the annual information only, a report thereon by the Issuers'
     independent certified public accountants; and
 
          (ii) all information that would be required to be filed with the
     Commission on Form 8-K if the Issuers were required to file such reports.
 
     In addition, together with the information provided in clauses (i) and (ii)
above, the Issuers have agreed to provide supplemental financial information to
the extent permitted by the Commission in the Management's Discussion and
Analysis of Financial Condition and Results of Operations section of such
reports or other section of such reports as appropriate consisting of revenue
(allocated between domestic and international operations), expense, earnings
before interest and taxes, net income, capital expenditures, cash, debt,
depreciation and amortization and subscriber data for the Company, ORBCOMM USA
and ORBCOMM International and reflecting elimination of intercompany
transactions. In the event the Commission does not permit such supplemental
financial information to be included in such reports, then the Issuers will
supply such information supplementally to the registered Holders, unless
providing such information supplementally would, in the reasonable judgment of
counsel to the Company, violate applicable law.
 
     The Indenture also provides that the Issuers will furnish to the Holders of
Senior Notes all information that OCC, Teleglobe Mobile, ORBCOMM USA and ORBCOMM
International would be required to file with the Commission if the Issuers were
required to file the public reports described above.
 
     In addition, whether or not required by the rules and regulations of the
Commission, but only if then permitted by the Commission, the Issuers and, to
the extent set forth in the preceding paragraph, OCC, Teleglobe Mobile, ORBCOMM
USA and ORBCOMM International have agreed to file a copy of all such information
and reports with the Commission for public availability and make such
information available to securities analysts and prospective investors upon
request. In addition, for so long as any Senior Notes remain outstanding, the
Issuers will furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.
 
EVENTS OF DEFAULT AND REMEDIES
 
          The Indenture provides that each of the following constitutes an Event
     of Default:
 
          (i) default for 30 days in the payment when due of interest (including
     Revenue Participation Interest, if any) on, or Liquidated Damages (if any)
     with respect to, the Senior Notes;
 
          (ii) default in payment when due (whether at maturity, upon redemption
     or repurchase, or otherwise) of the principal of or premium (if any) on the
     Senior Notes;
 
                                       99
<PAGE>   106
 
          (iii) default in the payment of principal and interest (including
     Revenue Participation Interest, if any) or Liquidated Damages (if any) on
     Senior Notes required to be purchased pursuant to the provisions described
     under the captions "-- Repurchase at the Option of Holders -- Change of
     Control," "-- Repurchase at the Option of Holders -- Limitations on Sales
     of Assets and Subsidiary Interests," or failure by the Credit Parties to
     comply with the provisions described under "-- Certain Covenants -- Merger,
     Consolidation or Sale of Assets;"
 
          (iv) failure by the Credit Parties or any of their Restricted
     Subsidiaries for 30 days after notice to comply with any of their other
     covenants in the Indenture or the Senior Notes;
 
          (v) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Credit Parties or any of their
     Restricted Subsidiaries (or the payment of which is guaranteed by the
     Credit Parties or any of their Restricted Subsidiaries), whether such
     Indebtedness or guarantee now exists, or is created after the date of the
     Indenture, which default:
 
             (a) is caused by a failure to pay principal of, or premium, if any,
        or interest on, such Indebtedness prior to the expiration of the grace
        period provided in such Indebtedness on the date of such default (a
        "Payment Default"); or
 
             (b) results in the acceleration (which acceleration has not been
        rescinded) of such Indebtedness prior to its express maturity, and, in
        each case described in clauses (a) and (b) of this paragraph, the
        principal amount of any such Indebtedness, together with the principal
        amount of any other such Indebtedness under which there has been a
        Payment Default or the maturity of which has been so accelerated,
        aggregates $5 million or more;
 
          (vi) failure by the Credit Parties or any of their Restricted
     Subsidiaries to pay final judgments (other than any judgments as to which a
     reputable insurance company has accepted full liability and whose bond,
     premium or similar charge therefor is not in excess of $5 million)
     aggregating in excess of $5 million, which judgments are not paid,
     discharged or stayed within 60 days after their entry;
 
          (vii) breach by the Issuers of any representation or warranty set
     forth in the Pledge Agreement, or default by the Issuers in the performance
     of any covenant set forth in the Pledge Agreement, or repudiation by the
     Issuers of any of their obligations under the Pledge Agreement or the
     unenforceability of the Pledge Agreement against the Issuers for any reason
     which in any one case or in the aggregate results in a material impairment
     of the rights intended to be afforded thereby;
 
          (viii) termination or loss, for any reason, of the FCC License;
 
          (ix) certain events of bankruptcy or insolvency with respect to the
     Credit Parties or any of their Restricted Subsidiaries; and
 
          (x) any Guarantee of the Senior Notes shall be held in a judicial
     proceeding to be unenforceable or invalid or shall cease for any reason to
     be in full force and effect, or any Guarantor, or any person acting on
     behalf of any Guarantor, shall deny or disaffirm its obligations under its
     Guarantee of any Notes.
 
     If any Event of Default occurs and is continuing with respect to the Senior
Notes, the Trustee or the Holders of at least 25% of the aggregate principal
amount of the then outstanding Senior Notes may declare all the Senior Notes to
be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency with
respect to the Issuers, any Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary,
all outstanding Senior Notes will become due and payable without further action
or notice. Holders of the Senior Notes may not enforce the Indenture or the
Senior Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Senior Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the Senior Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.
 
                                       100
<PAGE>   107
 
     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Issuers with
the intention of avoiding payment of the premium that the Issuers would have had
to pay if the Issuers then had elected to redeem the Senior Notes pursuant to
the optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable upon the acceleration of the
Senior Notes. If an Event of Default occurs prior to August 15, 2001 by reason
of any such willful action (or inaction), by or on behalf of the Issuers with
the intention of avoiding the prohibition on redemption of the Senior Notes
prior to August 15, 2001, then the premium specified in the Indenture shall also
become immediately due and payable to the extent permitted by law upon the
acceleration of the Senior Notes.
 
     The Holders of a majority in aggregate principal amount of the Senior Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Senior Notes waive any existing Default or Event of Default and its
consequences under the Indenture, except a continuing Default or Event of
Default in the payment of interest (including Revenue Participation Interest, if
any) on, or the principal of, the Senior Notes.
 
     The Credit Parties are required to deliver to the Trustee quarterly a
statement regarding compliance with the Indenture, and the Credit Parties are
required, upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, PARTNERS, OFFICERS, EMPLOYEES, INCORPORATORS
AND STOCKHOLDERS
 
     No director, general or limited partner of any Credit Party, authorized
representative of a general partner of any Credit Party, or officer, employee,
incorporator or stockholder of any Credit Party, as such, shall have any
liability for any obligations of the Credit Parties under the Senior Notes, the
Indenture or the Pledge Agreement or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder of Senior Notes,
by accepting a Senior Note, waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Senior Notes. Such
waiver may not be effective to waive liabilities under the federal securities
laws and it is the view of the Commission that such a waiver is against public
policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Issuers may, at their option and at any time, elect to have all of
their obligations discharged with respect to the outstanding Senior Notes
("Legal Defeasance") except for:
 
          (i) the rights of Holders of outstanding Senior Notes to receive
     payments in respect of the principal of, and premium (if any), interest and
     Liquidated Damages (if any) on, such Senior Notes when such payments are
     due from the trust referred to below;
 
          (ii) the Issuers' obligations with respect to the Senior Notes
     concerning issuing temporary Senior Notes, registration of Senior Notes,
     mutilated, destroyed, lost or stolen Notes and the maintenance of an office
     or agency for payment and money for security payments held in trust;
 
          (iii) the rights, powers, trusts, duties and immunities of the
     Trustee, and the Issuers' obligations in connection therewith; and
 
          (iv) the Legal Defeasance provisions of the Indenture.
 
     In addition, the Issuers may, at their option and at any time, elect to
have the obligations of the Issuers released with respect to certain covenants
that are described in the Indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or Event
of Default with respect to the Senior Notes. In the event Covenant Defeasance
occurs, certain events (other than non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "-- Events of Default"
will no longer constitute an Event of Default with respect to the Senior Notes.
 
                                       101
<PAGE>   108
 
     In order to exercise either Legal Defeasance or Covenant Defeasance with
respect to the Senior Notes:
 
          (i) the Issuers must irrevocably deposit with the Trustee, in trust
     for the benefit of the Holders of the Senior Notes, cash in U.S. dollars,
     non-callable Government Securities or a combination thereof, in such
     amounts as will be sufficient, in the opinion of a nationally recognized
     firm of independent certified public accountants, to pay the principal of,
     and premium (if any), interest (including Revenue Participation Interest)
     and Liquidated Damages (if any) on, the outstanding Senior Notes on the
     stated maturity or on the applicable redemption date, as the case may be,
     and the Company must specify whether the Senior Notes are being defeased to
     maturity or to a particular redemption date;
 
          (ii) in the case of Legal Defeasance, the Issuers shall have delivered
     to the Trustee an opinion of counsel in the United States reasonably
     acceptable to the Trustee confirming that:
 
             (A) the Issuers have received from, or there has been published by,
        the Internal Revenue Service a ruling, or
 
             (B) since the date of the Indenture, there has been a change in the
        applicable federal income tax law,
 
     in either case to the effect, and based thereon such opinion of counsel
     shall confirm, that the Holders of the outstanding Notes will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     Legal Defeasance and will be subject to federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such Legal Defeasance had not occurred;
 
          (iii) in the case of Covenant Defeasance, the Issuers shall have
     delivered to the Trustee an opinion of counsel in the United States
     reasonably acceptable to the Trustee confirming that the Holders of the
     outstanding Senior Notes will not recognize income, gain or loss for
     federal income tax purposes as a result of such Covenant Defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Covenant
     Defeasance had not occurred;
 
          (iv) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the 91st day
     after the date of deposit;
 
          (v) such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute default under any material agreement
     or instrument (other than the Indenture) to which the Issuers or any of
     their Restricted Subsidiaries is a party or by which the Issuers or any of
     their Restricted Subsidiaries is bound;
 
          (vi) the Issuers shall have delivered to the Trustee an opinion of
     counsel to the effect that after the 91st day (or such other applicable
     date) following the deposit, the trust funds will not be subject to the
     effect of any applicable bankruptcy, insolvency, reorganization or similar
     laws affecting creditors' rights generally;
 
          (vii) the Issuers shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Issuers with the
     intent of preferring the Holders of Senior Notes over the other creditors
     of the Issuers with the intent of defeating, hindering, delaying or
     defrauding creditors of the Issuers or others; and
 
          (viii) the Issuers shall have delivered to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that all conditions
     precedent provided for relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Senior Notes in accordance with the
Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer
 
                                       102
<PAGE>   109
 
documents and the Issuers may require a Holder to pay any taxes and fees
required by law or permitted by the Indenture. The Issuers are not required to
transfer or exchange any Senior Notes selected for redemption. Also, the Issuers
are not required to transfer or exchange any Senior Notes for a period of 15
days before a selection of Senior Notes to be redeemed.
 
     The registered Holder of a Senior Note will be treated as the owner of such
Senior Note for all purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next succeeding paragraph, the Indenture, the
Senior Notes and the Pledge Agreement may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Senior
Notes then outstanding (including consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Senior Notes), and any
existing default or compliance with any provision of the Indenture, the Senior
Notes or the Pledge Agreement may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Senior Notes (including
consents obtained in connection with a tender offer or exchange offer for Senior
Notes).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Note held by a non-consenting Holder):
 
          (i) reduce the principal amount of Senior Notes whose Holders must
     consent to an amendment, supplement or waiver;
 
          (ii) reduce the principal of or change the fixed maturity of any
     Senior Note or alter the provisions with respect to the redemption of the
     Senior Notes (other than provisions relating to the covenants described
     above under the caption "-- Repurchase at the Option of Holders");
 
          (iii) reduce the rate of or change the time for payment of interest
     (including Revenue Participation Interest, if any) on any Senior Note;
 
          (iv) waive a Default or Event of Default in the payment of principal
     of, premium (if any), interest or Liquidated Damages (if any) on, the
     Senior Notes (except a rescission of acceleration of the Senior Notes by
     the Holders of at least a majority in aggregate principal amount of the
     Senior Notes and a waiver of the payment default that resulted from such
     acceleration);
 
          (v) make any Senior Note payable in money other than that stated in
     the Senior Notes;
 
          (vi) make any change in the provisions of the Indenture relating to
     waivers of past Defaults or the rights of Holders of Senior Notes to
     receive payments of principal of, premium (if any), interest (including
     Revenue Participation Interest, if any) or Liquidated Damages on, the
     Senior Notes;
 
          (vii) waive a redemption payment with respect to any Senior Note
     (other than a payment required by one of the covenants described above
     under the caption "-- Repurchase at the Option of Holders"); or
 
          (viii) make any change in the foregoing amendment and waiver
     provisions.
 
     Notwithstanding the foregoing, without the consent of any Holder of Senior
Notes, the Credit Parties and the Trustee may amend or supplement the Indenture,
the Senior Notes or the Pledge Agreement to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Senior Notes in addition to or in
place of certificated Senior Notes, to provide for the assumption of the Credit
Parties' obligations to Holders of Senior Notes in the case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the Holders of Senior Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder, or to comply with
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Issuers, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
 
                                       103
<PAGE>   110
 
such claim as security or otherwise. The Trustee will be permitted to engage in
other transactions; however, if the Trustee acquires any conflicting interest,
it must eliminate such conflict within 90 days, apply to the Commission for
permission to continue or resign.
 
     The Holders of a majority in principal amount of the then outstanding
Senior Notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. The Indenture provides that in case an Event of
Default shall occur (which shall not be cured), the Trustee will be required, in
the exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any Holder of Senior Notes, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.

BOOK-ENTRY, DELIVERY AND FORM
 
     Except as set forth in the next paragraph, the Exchange Notes to be issued
as set forth herein will initially be issued in the form of one Global Note (the
"Global Note"). The Global Note will be deposited on the date of the closing of
the exchange of the Exchange Notes offered hereby (the "Closing Date") with, or
on behalf of, the Depositary and registered in the name of Cede & Co., as
nominee of the Depositary (such nominee being referred to herein as the "Global
Note Holder").
 
                                       115
<PAGE>   122
 
     Exchange Notes that are issued as described below under "-- Certificated
Securities" will be issued in the form of registered definitive certificates
(the "Certificated Securities"). Upon the transfer of Certificated Securities,
such Certificated Securities may, unless the Global Note has previously been
exchanged for Certificated Securities, be exchanged for an interest in the
Global Note representing the principal amount of Notes being transferred.
 
     The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the Initial
Purchasers), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only through the Depositary's
Participants or the Depositary's Indirect Participants.
 
     The Issuers expect that pursuant to procedures established by the
Depositary: (i) upon deposit of the Global Note, the Depositary will credit the
accounts of Participants designated by the Exchange Agent with portions of the
principal amount of the Global Note; and (ii) ownership of the Exchange Notes
evidenced by the Global Note will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by the Depositary
(with respect to the interests of the Depositary's Participants), the
Depositary's Participants and the Depositary's Indirect Participants. The laws
of some states require that certain persons take physical delivery in definitive
form of securities that they own. Consequently, the ability to transfer Exchange
Notes evidenced by the Global Note will be limited to such extent.
 
     So long as the Global Note Holder is the registered owner of any Senior
Notes, the Global Note Holder will be considered the sole Holder under the
Indenture of any Senior Notes evidenced by the Global Note. Beneficial owners of
Senior Notes evidenced by the Global Note will not be considered the owners or
Holders thereof under the Indenture for any purpose, including with respect to
the giving of any directions, instructions or approvals to the Trustee
thereunder. Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records of the Depositary or for maintaining,
supervising or reviewing any records of the Depositary relating to the Notes.
 
     Payments in respect of the principal of, and premium, interest on, any
Senior Notes registered in the name of the Global Note Holder on the applicable
record date will be payable by the Trustee to or at the direction of the Global
Note Holder in its capacity as the registered Holder under the Indenture. Under
the terms of the Indenture, the Issuers and the Trustee may treat the persons in
whose names Senior Notes, including the Global Note, are registered as the
owners thereof for the purpose of receiving such payments. Consequently, neither
the Issuers nor the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Senior Notes. The Issuers
believe, however, that it is currently the policy of the Depositary to credit
immediately the accounts of the relevant Participants with such payments, in
amounts proportionate to their respective holdings of beneficial interests in
the relevant security as shown on the records of the Depositary. Payments by the
Depositary's Participants and the Depositary's Indirect Participants to the
beneficial owners of Senior Notes will be governed by standing instructions and
customary practice and will be the responsibility of the Depositary's
Participants or the Depositary's Indirect Participants.
 
CERTIFICATED SECURITIES
 
     Subject to certain conditions, any person having a beneficial interest in
the Global Note may, upon request to the Trustee, exchange such beneficial
interest for Senior Notes in the form of Certificated Securities. Upon any such
issuance, the Trustee is required to register such Certificated Securities in
the name of, and cause the same to be delivered to, such person or persons (or
the nominee of any thereof). All such certificated Senior Notes would be subject
to the legend requirements described herein under "Notice to
 
                                       116
<PAGE>   123
 
Investors." In addition, if: (i) the Issuers notify the Trustee in writing that
the Depositary is no longer willing or able to act as a depositary and the
Issuers are unable to locate a qualified successor within 90 days; or (ii) the
Issuers, at their option, notify the Trustee in writing that they elect to cause
the issuance of Senior Notes in the form of Certificated Securities under the
Indenture, then, upon surrender by the Global Note Holder of its Global Note,
Senior Notes in such form will be issued to each person that the Global Note
Holder and the Depositary identify as being the beneficial owner of the related
Senior Notes.
 
     Neither the Issuers nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Senior Notes and the Issuers and the Trustee may conclusively rely on, and will
be protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
     The Indenture requires that payments in respect of the Senior Notes
represented by the Global Note be made by wire transfer of immediately available
funds to the accounts specified by the Global Note Holder. With respect to
Certificated Securities, the Issuers will make all payments of principal,
premium, interest and Liquidated Damages, if any, by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each such Holder's
registered address. Secondary trading in long-term notes and debentures of
corporate issuers is generally settled in clearing-house or next-day funds. In
contrast, the Notes represented by the Global Note are expected to be eligible
to trade in the PORTAL Market and to trade in the Depositary's Same-Day Funds
Settlement System, and any permitted secondary market trading activity in such
Notes will, therefore, be required by the Depositary to be settled in
immediately available funds. The Issuers expect that secondary trading in the
Certificated Securities also will be settled in immediately available funds.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that participates in the Exchange Offer (a
"Participating Broker-Dealer") and receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer in connection with the resale of Exchange Notes
received in exchange for Old Notes where such Old Notes were acquired as a
result of market-making activities or other trading activities. The Issuers have
agreed that for a period of 180 days after the Expiration Date, they will make
this Prospectus, as amended or supplemented, available to any Participating
Broker-Dealer for use in connection with any such resale. In addition, until
            , 1996, all dealers effecting transactions in the Exchange Notes may
be required to deliver a prospectus.
 
     The Issuers will not receive any proceeds from any sale of Exchange Notes
by Participating Broker-Dealers. Exchange Notes received by Participating
Broker-Dealers for their own account pursuant to the Exchange Offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the Exchange Notes or
a combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any Participating Broker-Dealer and/or the purchasers of any
such Exchange Notes. Any Participating Broker-Dealer that resells Exchange Notes
that were received by it for its own account pursuant to the Exchange Offer and
any broker or dealer that participates in a distribution of such Exchange Notes
may be deemed to be an "underwriter" within the meaning of the Securities Act
and any profit on any such sale of Exchange Notes and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
Participating Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
     For a period of 180 days after the Expiration Date, the Issuers will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any Participating Broker-Dealer that requests
such documents in the Letter of Transmittal.
 
     The Issuers have agreed in the Registration Rights Agreement to indemnify
each Participating Broker-Dealer reselling Exchange Notes pursuant to this
Prospectus, and their officers, directors and controlling persons, against
certain liabilities in connection with the offer and sale of the Exchange Notes,
including liabilities under the Securities Act, or to contribute to payments
that such Participating Broker-Dealers may be required to make in respect
thereof. The Issuers have agreed to pay all of the expenses incurred in this
Exchange Offer, other than commissions or concessions of any participating
Brokers-Dealers.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     Latham & Watkins, counsel to the Company, has advised the Company that the
following discussion expresses its opinion as to the material federal income tax
consequences expected to result to holders whose Old Notes are exchanged for
Exchange Notes in the Exchange Offer. The signed opinion of Latham & Watkins is
filed as an exhibit to the Registration Statement of which this Prospectus forms
a part. Such opinion is based upon current provisions of the Internal Revenue
Code of 1986, as amended, applicable Treasury Regulations, judicial authority
and administrative rulings and practice. There can be no assurance that the
Internal Revenue Service (the "Service") will not take a contrary view, and no
ruling from the Service has been or will be sought. Legislative, judicial or
administrative changes or interpretations may be forthcoming that could alter or
modify the statements and conclusions set forth herein. Any such changes or
interpretations may or may not be retroactive and could affect the tax
consequences to holders. Certain Holders (including insurance companies,
tax-exempt organizations, financial institutions, broker-dealers, foreign
corporations and persons who are not citizens or residents of the United States)
may be subject to special rules not discussed below. EACH HOLDER OF OLD NOTES
SHOULD CONSULT HIS OR HER OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES
OF EXCHANG-
 
                                       118
<PAGE>   125
 
ING OLD NOTES FOR EXCHANGE NOTES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY
STATE, LOCAL OR FOREIGN TAX LAWS.
 
   
     The exchange of Old Notes for Exchange Notes will be treated as a
"non-event" for federal income tax purposes because the Notes will not be
considered to differ materially in kind or extent from the Old Notes. As a

                          INDEPENDENT AUDITORS' REPORT
 
The Partners
  ORBCOMM Global, L.P.:
 
     We have audited the accompanying statements of assets, liabilities and
partners' capital of ORBCOMM Global, L.P. (the "Company") (a development stage
enterprise) as of December 31, 1995 and 1994, and the related statements of
income and expenses, partners' capital, and cash flows for each of the years
then ended and for the period from June 30, 1993 (date of inception) to December
31, 1993 and for the period from June 30, 1993 (date of inception) through
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 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 financial position of the Company (a development
stage enterprise) as of December 31, 1995 and 1994, and the results of its
income and expenses, partners' capital and cash flows for each of the years then
ended and for the period from June 30, 1993 (date of inception) through December
31, 1993 and for the period from June 30, 1993 (date of inception) through
December 31, 1995, in conformity with generally accepted accounting principles.

                        (A DEVELOPMENT STAGE ENTERPRISE)
 
                         NOTES TO FINANCIAL STATEMENTS
 
(1)  THE ORBCOMM SYSTEM
 
  Organization
 
     In 1993, Orbital Communications Corporation ("OCC"), a majority owned
subsidiary of Orbital Sciences Corporation ("Orbital"), and Teleglobe Mobile
Partners ("Teleglobe Mobile"), a partnership established by affiliates of
Teleglobe Inc. ("Teleglobe"), formed ORBCOMM Global, L.P. ("ORBCOMM" or "the
Company"), a Delaware limited partnership.
 
     Pursuant to the terms of the Agreement of Limited Partnership of the
Company, action by the Company generally requires the approval of General
Partners holding a majority of the Participation Percentages held by the General
Partners. OCC and Teleglobe Mobile each holds 50% of the Participation
Percentages in the Company, with the result that the approval of both OCC and
Teleglobe Mobile is generally necessary for the Company to act.
 
     The Company is a 98% noncontrolling General Partner in ORBCOMM USA, L.P.
("ORBCOMM USA") and ORBCOMM International Partners, L.P. ("ORBCOMM
International"), two partnerships formed to market the ORBCOMM System services
in the United States and internationally, respectively.
 
  The ORBCOMM System Description
 
     The Company was created for the design, development, construction,
integration, testing and operation of the ORBCOMM System. The Company intends to
construct and implement the initial 28-satellite ORBCOMM System in two phases:
the ORBCOMM Phase 1A System, consisting of the worldwide network operations
center (including the satellite management system), the U.S. Gateway control
center, four U.S. Earth stations and two satellites; and the ORBCOMM Phase 1B
System consisting of the ORBCOMM Phase 1A System, three additional planes each
consisting of eight satellites and one plane consisting of two high-inclination
satellites.
 
     Orbital is the primary supplier of the communications satellites, launch
vehicles and U.S. ground systems and successfully launched the Phase 1A
satellites in April 1995. The Phase 1A System began commercial intermittent
service in 1996.
 
  The System Charge
 
     OCC is obligated to pay to the Company a System Charge in consideration of
the construction and financing of the ORBCOMM System Assets by the Company.
Teleglobe Mobile is obligated to pay to the Company a System Charge in
consideration of the Company's grant to Teleglobe Mobile of the right to market,
sell, lease and franchise all ORBCOMM System output capacity outside the United
States.
 
  Regulatory Status
 
   
     Construction and operation of communications satellites in the United
States requires licenses from the Federal Communications Commission ("FCC"). OCC
has been granted full operational authority for the ORBCOMM System by the FCC.
Similar licenses are required from foreign regulatory authorities to permit
ORBCOMM System services to be offered outside the United States. Primary
responsibility for obtaining licenses outside the United States will reside with
entities who become International Licensees.
    
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The Company is in its development stage, devoting substantially all of its
efforts to establishing a new communications business. The Company's planned
principal operations are expected to commence in 1998.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
The accompanying financial statements have been prepared on the accrual basis of
accounting in conformity with generally accepted accounting principles in the
United States.
 
     In the opinion of management, the accompanying unaudited interim financial
information reflects all adjustments, consisting of normal recurring accruals,
necessary for a fair presentation thereof. Operating results for the six-month
periods ended June 30, 1996 and 1995 are not necessarily indicative of the
results expected for the full year.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
  Depreciation and Recoverability of Long-Lived Assets
 
     Depreciation is provided over an asset's estimated economic useful life
using the straight-line method as follows:
 
<TABLE>
        <S>                              <C>
        Space Segment Assets:            lesser of five years or estimated life of the satellite
        Ground Segment Assets:           10 years
        Furniture and Equipment:         3 to 10 years
</TABLE>
 
     The Company anticipates depreciating the ORBCOMM System over the estimated
economic useful lives of the various ORBCOMM System components once the ORBCOMM
System is placed in service. The Phase 1A System, which includes the worldwide
network operations center (including the satellite management system), the U.S.
Gateway control center, four U.S. Earth stations and two satellites, was placed
in service at the beginning of 1996, at which time the Company began
depreciating those assets. The Company anticipates that the ORBCOMM Phase 1B
System will become fully operational in 1998.
 
     The Company's policy is to review its long-lived assets, including its
satellite systems, for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. The
Company recognizes an impairment loss when the sum of the expected future cash
flows is less than the carrying amount of the asset. Given the inherent
technical and commercial risks within the space communications industry, it is
reasonably possible that the Company's current estimate that it will recover the
carrying amount of its long-lived assets from future operations may change.
 
  Investments in Affiliates
 
     Pursuant to the terms of ORBCOMM USA's and ORBCOMM International's
partnership agreements, OCC controls the operational and financial affairs of
ORBCOMM USA and Teleglobe Mobile controls the operational and financial affairs
of ORBCOMM International. The Company, however, significantly influences both
marketing partnerships. Accordingly, the Company is accounting for its
investments in ORBCOMM USA and ORBCOMM International using the equity method.
 
     Pursuant to the equity method of accounting, the Company's carrying amount
of an investment is initially recorded at cost and is increased to reflect its
share of the affiliate's income, and is reduced to reflect its share of the
affiliate's losses. The Company's investment is also increased to reflect
contributions to, and reduced to reflect distributions from, such affiliates.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

  Income Taxes
 
     As a partnership, Federal and state income taxes are the direct
responsibility of each partner. Accordingly, no income taxes have been recorded
in the accompanying financial statements.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.
 
  Inventory
 
     Inventory is stated at lower of cost, determined on the specific
identification basis, or market and generally represents amounts paid to
subcontractors for subscriber communicators.
 
  Fair Value of Financial Instruments
 
     The carrying value of the Company's cash and cash equivalents, receivables,
and accounts payables approximates fair value since all such instruments are
short-term in nature. Fair value for the Company's secured note payable is
determined based on current rates offered for debt of similar remaining
maturities. At June 30, 1995 (unaudited) and 1996 (unaudited), and December 31,
1994 and 1995, the fair value for the secured note payable approximated carrying
value.
 
  Mobile Communications Satellite System Under Construction
 
     During the construction of the ORBCOMM System, the Company is capitalizing
substantially all such construction costs. Additionally, interest costs of
$222,338, $183,626 and $425,765 has been capitalized as a part of the historical
cost of the ORBCOMM System at June 30, 1995 (unaudited) and 1996 (unaudited) and
December 31, 1995, respectively (none in 1994).
 
  Revenue Recognition
 
     The Company provides subscriber communicator hardware to ORBCOMM USA and
ORBCOMM International at cost. Revenue is recognized when products are shipped
or when clients have accepted the products or services, depending on contractual
terms. Contract revenues and receivables are recognized and accrued as contract
costs are incurred. Related contract expenses incurred in providing U.S.
Marketing Services are recognized on the accrual basis of accounting.
 
     The Company generally recognizes fees from international service license
agreements ratably over the term of the agreement, or when the Company's
obligations under the agreement are substantially complete.

(4)  LONG-TERM DEBT
    
 
     The Company has a $5,000,000 secured note outstanding with a financial
institution, which bears interest at 9.2% per annum and is due in monthly
principal and interest installments of $104,278 through December 1999. The note
is secured by equipment located at certain of the U.S. Earth stations, network
operations center and satellite control center, and is guaranteed by Orbital.
 
   
(5)  RELATED PARTY TRANSACTIONS
    
 
   
     The Company paid Orbital approximately $15,800,000, $25,000,000,
$48,000,000, $11,000,000, and $38,000,000 for the period ended June 30, 1995
(unaudited) and 1996 (unaudited) and the period June 30, 1993 (date of
inception) through December 31, 1993, and the years ended December 31, 1994 and
1995, respectively, for work performed pursuant to the ORBCOMM System Design,
Development, and Operations Agreement (for the ORBCOMM Phase 1A System) and the
ORBCOMM System Procurement Agreement (for the ORBCOMM Phase 1B System) and the
Administrative Services Agreement (for provision of ongoing support to the
Company).
    
 
   
     In 1995, pursuant to the terms of the ORBCOMM System Design, Development
and Operations Agreement, the Company reimbursed OCC $1,375,000 for previous
costs incurred in obtaining the FCC License and other related costs. The Company
capitalized such costs as part of its mobile communications satellite system.
(See Note 3)
    
 
     At June 30, 1996 (unaudited), the Company has a receivable of approximately
$112,000 for a bonus payment to the Company's employees paid on behalf of OCC
for employees previously employed by OCC (none for the periods ended December
31, 1995 and 1994).
 
   
(6)  SUBSEQUENT EVENTS
    
 
   
     In August 1996, ORBCOMM and ORBCOMM Global Capital Corp. (the "Issuers")
issued $170,000,000 of Senior Notes due in 2004 with Revenue Participation
Interest (the " Old Notes"). Revenue Participation Interest represents an
aggregate amount equal to 5.0% of the ORBCOMM System revenue and is payable on
the Notes on each interest payment date subject to certain covenant
restrictions. Interest on the Old Notes will accrue at a rate of 14% per annum
and will be payable semi-annually in arrears on February 15 and August 15 of
each year, commencing on February 15, 1997.
    
 
   
     The Old Notes are exchangeable for an equal principal amount of registered
14% Series B Senior Notes due 2004 with Revenue Participation Interest (the
"Exchange Notes"). The Exchange Notes are substantially identical in form and
term to the Old Notes except that the Exchange Notes have been registered under
the Securities Act of 1933, as amended, and do not bear legends restricting the
transfer thereof. The Exchange

Notes and the Old Notes are collectively referred to as the "Notes." The Notes
are fully and unconditionally guaranteed on a joint and several basis by OCC,
Teleglobe Mobile, ORBCOMM USA and ORBCOMM International (each, a "Guarantor" and
collectively, the "Guarantors"), limited only to the extent necessary for each
such guarantee to not constitute a fraudulent conveyance under applicable law.
The guarantee of each Guarantor ranks pari passu in right of payment with all
senior indebtedness of such Guarantor and senior in right of payment to all
indebtedness expressly subordinated to the guarantee of such Guarantor. The
guarantees are nonrecourse to the shareholders and/or partners of each Guarantor
and no shareholder or partner of any Guarantor will have any liability for any
claim under the Notes.
    
 
   
     Upon closing, the Company used a portion of the net proceeds from the sale
of the Old Notes to purchase a portfolio of United States government securities
to provide for payment in full of interest on the Notes through August 15, 1998
(estimated at approximately $44.8 million).

The Partners
  ORBCOMM USA, L.P.:
 
     We have audited the accompanying statements of assets, liabilities and
partners' capital of ORBCOMM USA, L.P. ("ORBCOMM USA") (a development stage
enterprise) as of December 31, 1995 and 1994, and the related statements of

then ended and for the period from June 30, 1993 (date of inception) to December
31, 1993 and for the period from June 30, 1993 (date of inception) through
December 31, 1995. These financial statements are the responsibility of ORBCOMM
USA'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 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 financial position of ORBCOMM USA (a development
stage enterprise) as of December 31, 1995 and 1994, and the results of its
income and expenses, partners' capital and cash flows for each of the years then
ended and for the period from June 30, 1993 (date of inception) to December 31,
1993 and for the period June 30, 1993 (date of inception) through December 31,
1995, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1)  THE ORBCOMM SYSTEM
 
  Organization
 
     In 1993, Orbital Communications Corporation ("OCC"), a majority owned
subsidiary of Orbital Sciences Corporation ("Orbital"), and Teleglobe Mobile
Partners ("Teleglobe Mobile"), a partnership established by affiliates of
Teleglobe Inc. ("Teleglobe"), formed ORBCOMM Global, L.P. ("ORBCOMM"), a
Delaware limited partnership.
 
     OCC and Teleglobe Mobile also formed two marketing partnerships, ORBCOMM
USA, L.P. ("ORBCOMM USA") and ORBCOMM International Partners, L.P. ("ORBCOMM
International"), to market the ORBCOMM System services in the United States and
internationally, respectively. In 1995, ORBCOMM became a 98% General Partner in
ORBCOMM USA, reducing OCC's General Partner interest to 2% and eliminating
Teleglobe Mobile's interest entirely.
 
     Pursuant to the terms of the Agreement of Limited Partnership of ORBCOMM
USA between OCC and ORBCOMM, action by ORBCOMM USA generally requires the
approval of General Partners holding a majority of the participating interests
held by the General Partners, with OCC and Teleglobe Mobile each voting their
direct and indirect Participation Percentages as a whole. OCC and Teleglobe
Mobile each currently holds 51% and 49%, respectively, of the direct and
indirect participating interests in ORBCOMM USA.
 
  The ORBCOMM System Description
 
     ORBCOMM was created for the design, development, construction, integration,
testing and operation of a global digital satellite communications system of
low-Earth orbiting mobile satellites and certain terrestrial facilities intended
to provide two-way data and messaging communications services throughout the
world ("the ORBCOMM System"). ORBCOMM intends to construct and implement the
initial 28-satellite ORBCOMM System in two phases: the ORBCOMM Phase 1A System,
consisting of the worldwide network operations center (including the satellite
management system), the U.S. Gateway control center, four U.S. Earth stations
and two satellites ("the ORBCOMM Phase 1A System"); and the ORBCOMM Phase 1B
System, consisting of the ORBCOMM Phase 1A System, three additional planes each
consisting of eight additional satellites and one plane consisting of two
high-inclination satellites ("the ORBCOMM Phase 1B System").
 
     Orbital is the primary supplier of the communications satellites, launch
vehicles and U.S. ground systems and successfully launched the satellites of the
ORBCOMM Phase 1A in April 1995. The ORBCOMM Phase 1A System began commercial
intermittent service in 1996.
 
  The Output Capacity Charge and the U.S. Marketing Services
 
   
     Pursuant to the terms of the System Charge Agreement between OCC and
ORBCOMM USA, ORBCOMM USA has agreed to pay OCC an Output Capacity Charge that is
a quarterly fee equal to 23% of its total aggregate service revenues for such
calendar quarter in exchange for the exclusive right to market, sell, lease and
franchise all ORBCOMM System output capacity in the United States and for the
exclusive use of the System Assets in the United States.
    
 
     Additionally, pursuant to the terms of the System Charge Agreement, through
September 12, 1995, ORBCOMM USA furnished all management, labor, facilities and
materials necessary to perform, on a best efforts basis, certain marketing
services in the United States (the "U.S. Marketing Services"), on a cost-
reimbursable basis. The U.S. Marketing Services portion of the Marketing
Agreement expired on September 12, 1995.

(1)  THE ORBCOMM SYSTEM -- (CONTINUED)

  Regulatory Status
 
     Construction and operation of communications satellites in the United
States requires licenses from the Federal Communications Commission ("FCC"). OCC
has been granted full operational authority for the ORBCOMM System by the FCC.
Similar licenses are required from foreign regulatory authorities to permit
ORBCOMM System services to be offered outside the United States. Primary
responsibility for obtaining licenses outside the United States will reside with
the various International Licensees.
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     ORBCOMM USA is in its development stage, devoting substantially all of its
efforts to establishing commercial and governmental markets in the United States
for the ORBCOMM System. ORBCOMM USA's planned principal operations are expected
to commence in 1998. The accompanying financial statements of ORBCOMM USA have
been prepared on the accrual basis of accounting in conformity with generally
accepted accounting principles in the United States.
 
     In the opinion of management, the accompanying unaudited interim financial
information reflects all adjustments, consisting of normal recurring accruals,
necessary for a fair presentation thereof. Operating results for the six-month
periods ended June 30, 1996 and 1995 are not necessarily indicative of the
results expected for the full year.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
  Income Taxes
 
     As a partnership, Federal and state income taxes are the direct
responsibility of each partner. Accordingly, no income taxes have been recorded
in the accompanying financial statements.
 
  Cash and Cash Equivalents
 
     ORBCOMM USA considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.
 
  Revenue Recognition
 
   
     ORBCOMM USA provides subscriber communicator hardware to commercial
companies. Revenue is recognized when products are shipped or when clients have
accepted the products or services, depending on contractual terms. Through
September 1995, ORBCOMM USA provided U.S. Marketing Services to OCC on a
cost-reimbursable basis.
    
 
(3)  RELATED PARTY TRANSACTIONS
 
     Payments to ORBCOMM USA for U.S. Marketing Services are based on ORBCOMM
USA's monthly costs incurred. For the periods June 30, 1995 (unaudited) and 1996
(unaudited) and for the period June 30, 1993 (date of inception) through
December 31, 1993, and the years ended December 31, 1994, and 1995,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(3)  RELATED PARTY TRANSACTIONS -- (CONTINUED)

   
ORBCOMM USA received and recorded as contract revenues approximately $886,000,
$0, $749,000, $2,093,000, and $1,360,000, respectively, from OCC as
reimbursement of costs for U.S. Marketing Services.
    
 
     At June 30, 1996 (unaudited), ORBCOMM USA has a receivable of approximately
$9,400, for bonus payments to ORBCOMM USA employees paid on behalf of OCC for
employees previously employed by OCC (none for the periods ended December 31,
1995 and 1994).
 
     At June 30, 1996 (unaudited) and December 31, 1995 and 1994, ORBCOMM USA
has a payable of approximately $2,102,000, $661,000, and $0, respectively, to
ORBCOMM for amounts advanced to support ORBCOMM USA establish commercial and
government markets. ORBCOMM USA is currently in development stage and obtains
funds to support operations through advances from ORBCOMM.
 
(4)  SUBSEQUENT EVENTS
 
   
     In August 1996, ORBCOMM and ORBCOMM Global Capital Corp. (the "Issuers")
issued $170,000,000 of Senior Notes due in 2004 with Revenue Participation
Interest (the "Old Notes"). Revenue Participation Interest represents an
aggregate amount equal to 5.0% of the ORBCOMM System revenue and is payable on
the Old Notes on each interest payment date subject to certain covenant
restrictions. Interest on the Old Notes will accrue at a rate of 14% per annum
and will be payable semi-annually in arrears on February 15 and August 15 of
each year, commencing on February 15, 1997.
    
 
   
     The Old Notes are exchangeable for an equal principal amount of registered
14% Series B Senior Notes due 2004 with Revenue Participation Interest (the
"Exchange Notes"). The Exchange Notes are substantially identical in form and
term to the Old Notes except that the Exchange Notes have been registered under
the Securities Act of 1933, as amended, and do not bear legends restricting the
transfer thereof. The Exchange Notes and the Old Notes are collectively referred
to as the "Notes." The Notes are fully and unconditionally guaranteed on a joint
and several basis by OCC, Teleglobe Mobile, ORBCOMM USA, and ORBCOMM
International (each, a "Guarantor" and collectively, the "Guarantors"), limited
only to the extent necessary for each such guarantee to not constitute a
fraudulent conveyance under applicable law. The guarantee of each Guarantor
ranks pari passu in right of payment with all senior indebtedness of such
Guarantor and senior in right of payment to all indebtedness expressly
subordinated to the guarantee of such Guarantor. The guarantees are nonrecourse
to the shareholders and/or partners of each Guarantor and no shareholder or
partner of any Guarantor will have any liability for any claim under the Notes.
    
 
   
     Upon closing, ORBCOMM used a portion of the net proceeds from the sale of
the Old Notes to purchase a portfolio of United States government securities to
provide for payment in full of interest on the Notes through August 15, 1998
(estimated at approximately $44.8 million).

                          INDEPENDENT AUDITORS' REPORT
 
The Partners
  ORBCOMM International Partners, L.P.:
 
     We have audited the accompanying statements of assets, liabilities and
partners' capital of ORBCOMM International Partners, L.P. ("ORBCOMM
International") (a development stage enterprise) as of December 31, 1995 and
1994, and the related statements of income and expenses, partners' capital, and
cash flows for each of the years then ended and for the period from June 30,
1993 (date of inception) to December 31, 1993 and for the period from June 30,
1993 (date of inception) through December 31, 1995. These financial statements
are the responsibility of ORBCOMM International'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 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 financial position of ORBCOMM International (a
development stage enterprise) as of December 31, 1995 and 1994, and the results
of its income and expenses, partners' capital and cash flows for each of the
years then ended and for the period from June 30, 1993 (date of inception) to
December 31, 1993 and for the period June 30, 1993 (date of inception) through
December 31, 1995, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1)  THE ORBCOMM SYSTEM
 
  Organization
 
     In 1993, Orbital Communications Corporation ("OCC"), a majority owned
subsidiary of Orbital Sciences Corporation ("Orbital"), and Teleglobe Mobile
Partners ("Teleglobe Mobile"), a partnership established by affiliates of
Teleglobe Inc. ("Teleglobe"), formed ORBCOMM Global, L.P. ("ORBCOMM"), a
Delaware limited partnership.
 
     OCC and Teleglobe Mobile also formed two marketing partnerships, ORBCOMM
USA, L.P. ("ORBCOMM USA") and ORBCOMM International Partners, L.P. ("ORBCOMM
International"), to market the ORBCOMM System services in the United States and
internationally, respectively. In 1995, ORBCOMM became a 98% General Partner in
ORBCOMM International, reducing Teleglobe Mobile's General Partner interest to
2% and eliminating OCC's interest entirely.
 
     Pursuant to the terms of the Agreement of Limited Partnership of ORBCOMM
International between Teleglobe Mobile and ORBCOMM, action by ORBCOMM
International generally requires the approval of General Partners holding a
majority of the participating interests held by the General Partners, with OCC
and Teleglobe Mobile each voting their direct and indirect participating
interests as a whole. OCC and Teleglobe Mobile each currently holds 49% and 51%,
respectively, of the direct and indirect Participation Percentages in ORBCOMM
International.
 
  The ORBCOMM System Description
 
     ORBCOMM was created for the design, development, construction, integration,
testing and operation of a global digital satellite communications system of
low-Earth orbiting mobile satellites and certain terrestrial facilities intended
to provide two-way data and messaging communications services throughout the
world ("the ORBCOMM System"). ORBCOMM intends to construct and implement the
initial 28-satellite ORBCOMM System in two phases: the ORBCOMM Phase 1A System,
consisting of the worldwide network operations center (including the satellite
management system), the U.S. Gateway control center, four U.S. Earth stations
and two satellites ("the ORBCOMM Phase 1A System"); and the ORBCOMM Phase 1B
System, consisting of the ORBCOMM Phase 1A System, three additional planes each
consisting of eight additional satellites and one plane consisting of two
high-inclination satellites ("the ORBCOMM Phase 1B System").
 
     Orbital is the primary supplier of the communications satellites, launch
vehicles and U.S. ground systems and successfully launched the satellites of the
ORBCOMM Phase 1A in April 1995. The ORBCOMM Phase 1A System began commercial
intermittent service in 1996.
 
  The Output Capacity Charge
 
   
     Pursuant to the terms of the International System Charge Agreement (the
"International System Charge Agreement") among ORBCOMM, Teleglobe Mobile and
ORBCOMM International, ORBCOMM International has agreed to pay to Teleglobe
Mobile an International Output Capacity Charge that is equal to 23% of its total
aggregate service revenues for a calendar quarter in exchange for the exclusive
right to market, sell, lease and franchise all ORBCOMM System output capacity
outside the United States.
    
 
  Regulatory Status
 
     Construction and operation of communications satellites in the United
States requires licenses from the Federal Communications Commission ("FCC"). OCC
has been granted full operational authority for the ORBCOMM System by the FCC.
Similar licenses are required from foreign regulatory authorities to permit

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

ORBCOMM System services to be offered outside the United States. Primary
responsibility for obtaining licenses outside the United States will reside with
the various International Licensees.
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     ORBCOMM International is in its development stage, devoting substantially
all of its efforts to establishing commercial and governmental markets, through
international licensees, for the ORBCOMM System internationally. ORBCOMM
International's planned principal operations are expected to commence in 1998.
The accompanying financial statements of ORBCOMM International have been
prepared on the accrual basis of accounting in conformity with generally
accepted accounting principles in the United States.
 
     In the opinion of management, the accompanying unaudited interim financial
information reflects all adjustments, consisting of normal recurring accruals,
necessary for a fair presentation thereof. Operating results for the six-month
periods ended June 30, 1996 and 1995 are not necessarily indicative of the
results expected for the full year.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
  Income Taxes
 
     As a partnership, Federal and state income taxes are the direct
responsibility of each partner. Accordingly, no income taxes have been recorded
in the accompanying financial statements.
 
  Cash and Cash Equivalents
 
     ORBCOMM International considers all highly liquid debt instruments
purchased with a maturity of three months or less to be cash equivalents.
 
  Related Party Transactions
 
     At June 30, 1996 (unaudited), ORBCOMM International has a receivable of
approximately $6,600, for bonus payments to ORBCOMM International employees paid
on behalf of OCC for employees previously employed by OCC (none for the periods
ended December 31, 1995 and 1994).
 
     At June 30, 1996 (unaudited), ORBCOMM International has a payable of
approximately $253,500, to ORBCOMM for amounts advanced to support ORBCOMM
International establish commercial and government markets (none for the periods
ended December 31, 1995 and 1994). ORBCOMM International is currently in
development stage and obtains funds to support operations through advances from
ORBCOMM.
 
(3)  SUBSEQUENT EVENTS
 
   
     In August 1996, ORBCOMM and ORBCOMM Global Capital Corp. (the "Issuers")
issued $170,000,000 of Senior Notes due in 2004 with Revenue Participation
Interest (the "Old Notes"). Revenue Participation Interest represents an
aggregate amount equal to 5.0% of the ORBCOMM System revenue and

is payable on the Notes on each interest payment date subject to certain
covenant restrictions. Interest on the Old Notes will accrue at a rate of 14%
per annum and will be payable semi-annually in arrears on February 15 and August
15 of each year, commencing on February 15, 1997.
    
 
   
     The Old Notes are exchangeable for an equal principal amount of registered
14% Series B Senior Notes due 2004 with Revenue Participation Interest (the
"Exchange Notes"). The Exchange Notes are substantially identical in form and
term to the Old Notes except that the Exchange Notes have been registered under
the Securities Act of 1933, as amended, and do not bear legends restricting the
transfer thereof. The Exchange Notes and the Old Notes are collectively referred
to as the "Notes." The Notes are fully and unconditionally guaranteed on a joint
and several basis by OCC, Teleglobe Mobile, ORBCOMM USA, and ORBCOMM
International (each, a "Guarantor" and collectively, the "Guarantors"), limited
only to the extent necessary for each such guarantee to not constitute a
fraudulent conveyance under applicable law. The guarantee of each Guarantor
ranks pari passu in right of payment with all senior indebtedness of such
Guarantor and senior in right of payment to all indebtedness expressly
subordinated to the guarantee of such Guarantor. The guarantees are nonrecourse
to the shareholders and/or partners of each Guarantor and no shareholder or
partner of any Guarantor will have any liability for any claim under the Notes.
    
 
   
     Upon closing, ORBCOMM used a portion of the net proceeds from the sale of
the Old Notes to purchase a portfolio of United States government securities to
provide for payment in full of interest on the Notes through August 15, 1998
(estimated at approximately $44.8 million).

responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated 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 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Orbital
Communications Corporation and subsidiary as of December 31, 1995 and 1994, and
the results of their operations and their cash flows for each of the years in
the three-year period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)  THE ORBCOMM SYSTEM
 
  Organization
 
     In 1990, Orbital Sciences Corporation ("Orbital") formed Orbital
Communications Corporation ("OCC") to develop and operate the first
satellite-based global two-way data and messaging communications system. In
1993, OCC formed ORBCOMM Global, L.P. ("ORBCOMM") with Teleglobe Mobile Partners
("Teleglobe Mobile"), an affiliate of Teleglobe Inc.
 
     OCC and Teleglobe Mobile are each 50% general partners in ORBCOMM.
Additionally, OCC is a 2% general partner in ORBCOMM USA, L.P. ("ORBCOMM USA"),
and Teleglobe Mobile is a 2% general partner in ORBCOMM International Partners,
L.P. ("ORBCOMM International"), two partnerships formed to market the ORBCOMM
System. ORBCOMM is a 98% non-controlling general partner in each of the two
marketing partnerships. Directly and indirectly, OCC currently holds 51% and 49%
of ORBCOMM USA and ORBCOMM International, respectively.
 
     OCC, a Delaware corporation, is a majority owned subsidiary of Orbital and
is included in Orbital's Consolidated Financial Statements. From inception
through December 1995, OCC was an operating company with employees working under
contract to ORBCOMM. At the beginning of 1996, all OCC employees transferred to
ORBCOMM, ORBCOMM USA or ORBCOMM International. Currently, OCC operates as a
holding company.
 
  The ORBCOMM System Description
 
     ORBCOMM was formed for the design, development, construction, integration,
test and operation of the ORBCOMM low-Earth orbit satellite communications
system (the "ORBCOMM System"). ORBCOMM intends to construct and implement the
initial 28-satellite ORBCOMM System in two phases: the ORBCOMM Phase 1A System,
consisting of the worldwide network operations center (including the satellite
management system), the United States gateway control center, four United States
gateway Earth stations and two satellites; and the ORBCOMM Phase 1B System
consisting of the ORBCOMM Phase 1A System, three additional planes each
consisting of eight satellites and one plane consisting of two high-inclination
satellites.
 
     ORBCOMM USA, a subsidiary of OCC, has been granted the exclusive right to
market, sell, lease and franchise the ORBCOMM System output capacity in the
United States and the exclusive use of the ORBCOMM System Assets in the United
States.
 
  System Charge
 
   
     In consideration of the construction and financing of the ORBCOMM System
Assets by ORBCOMM, OCC is obligated to pay ORBCOMM a System Charge equal to 23%
of ORBCOMM USA's total aggregate revenues (the "Output Capacity Charge") minus
1.15% of aggregate system service revenues, defined as the total of ORBCOMM USA
and ORBCOMM International total system service revenues. If the Output Capacity
Charge is less than 1.15% of aggregate system service revenues as described
above, then OCC is not required to pay any portion of the System Charge to
ORBCOMM. Through June 30, 1996, no such charges have been incurred.
    
 
  Regulatory Status
 
     Construction and operation of communications satellites in the United
States requires licenses from the Federal Communications Commission ("FCC"). OCC
has been granted full operational authority for the ORBCOMM System by the FCC.
Similar licenses are required from foreign regulatory authorities to permit

ORBCOMM System services to be offered outside the United States. Primary
responsibility for obtaining licenses outside the United States will reside with
the various International Licensees.
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Preparation of Consolidated Financial Statements
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of OCC and the
partnership in which OCC directly or indirectly controls the general partner
interests. All material transactions and accounts among consolidated entities
have been eliminated in consolidation.
 
  Revenue Recognition
 
     OCC recognizes revenues on long-term contracts using the percentage of
completion method of accounting. Accordingly, revenues on long-term fixed-price
contracts are recognized based on costs incurred in relation to total estimated
costs, or based on specific delivery terms and conditions. Anticipated contract
losses are recognized as they become known.
 
     OCC currently has no long-term contracts, but was the primary supplier of
the ORBCOMM Phase 1A System through completion of the system in April 1995.
 
  Presentation of Interim Financial Information (Unaudited)
 
     In the opinion of management, the accompanying unaudited interim
consolidated financial information reflects all adjustments, consisting of
normal recurring accruals, necessary for a fair presentation thereof. Operating
results for the six-month periods ended June 30, 1996 and 1995 are not
necessarily indicative of the results expected for the full year.
 
  Income Taxes
 
     OCC is included in Orbital's consolidated Federal income tax returns. OCC
determines its provision for income taxes as if it were filing on a separate
return basis.
 
     OCC recognizes income taxes using the asset and liability method. Under the
asset and liability method, deferred tax assets and liabilities are recognized
for the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

  Cash and Cash Equivalents
 
     OCC considers all highly liquid debt instruments purchased with an original
maturity of three months or less to be cash equivalents.
 
  Investments in Affiliates
 
     OCC uses the equity method of accounting for its investments in and
earnings of affiliates in which OCC has the ability to significantly influence,
but not control, such affiliate's operations. In accordance with the equity
method of accounting, OCC's carrying amount of an investment in an affiliate is
initially recorded at cost and is increased to reflect its share of the
affiliate's income and is reduced to reflect its share of the affiliate's
losses. OCC's investment is also increased to reflect contributions to, and
decreased to reflect distributions received from, the affiliate. Any difference
between the amount of OCC's investment and the amount of the underlying equity
in each affiliate's net assets is amortized over a period of twenty years.
 
  Fair Value of Financial Instruments
 
     The carrying value of OCC's cash and cash equivalents, receivables, and
accounts payable approximates fair value since all such instruments are
short-term in nature.
 
(3)  RECEIVABLES
 
     The components of receivables are as follows:

(4)  INVESTMENTS IN AFFILIATES
 
     ORBCOMM Partnerships.  OCC's and Teleglobe Mobile's total capital
commitments to ORBCOMM are approximately $75,000,000 and $85,000,000,
respectively, of which approximately $71,000,000 and $59,000,000, respectively,
had been contributed through June 30, 1996 (unaudited). Capital contributions by
OCC and Teleglobe Mobile through December 31, 1995 were approximately
$62,000,000 and $35,000,000, respectively.
 
     Pursuant to the terms of the relevant partnership agreements, (i) OCC and
Teleglobe Mobile share equal responsibility for the operational and financial
affairs of ORBCOMM; (ii) OCC controls the operational and financial affairs of
ORBCOMM USA; and (iii) Teleglobe Mobile controls the operational and financial
affairs of ORBCOMM International. Since OCC is unable to control, but is able to
exercise significant influence over, ORBCOMM's and ORBCOMM International's
operating and financial policies, OCC is accounting for its investment in
ORBCOMM and ORBCOMM International using the equity method of accounting. Since
OCC is able to control the operational and financial affairs of ORBCOMM USA, the
Company consolidates the accounts of ORBCOMM USA.
 
     At June 30, 1996 (unaudited), ORBCOMM had total assets, total liabilities
and total partners' capital of approximately $134,826,000, $16,220,000 and
$118,606,000, respectively. At December 31, 1995, ORBCOMM had total assets,
total liabilities and total partners' capital of approximately $109,030,000,
$14,428,000 and $94,602,000, respectively. ORBCOMM collected a non-refundable
fee in the amount of

approximately $900,000 from a potential international licensee in 1995 (none in
prior years) and net income (loss) of approximately $55,000, ($9,000), and $0
for the years ended December 31, 1995, 1994, and 1993, respectively.
 
     Based on its current assessment of the overall business prospects of the
ORBCOMM partnerships and the ORBCOMM System, OCC currently believes its
investment of approximately $67,763,000 in ORBCOMM is fully recoverable. If, in
the future, implementation of the ORBCOMM System is significantly delayed,
significantly restricted or abandoned, OCC may be required to write-off part or
all of its investment.
 
(5)  RELATED PARTY TRANSACTIONS
 
     OCC was the prime contractor of the ORBCOMM Phase 1A System communications
satellites, launch vehicles and ground systems to ORBCOMM, and successfully
launched the ORBCOMM Phase 1A System satellites in April 1995. During the fiscal
years 1995, 1994, and 1993, OCC recorded contract revenues on sales to ORBCOMM
of approximately $15,652,000, $24,700,000 and $43,925,000, respectively.
 
     Pursuant to the ORBCOMM Phase 1A System contract with ORBCOMM, OCC
subcontracted with Orbital to procure a majority of the communications
satellites, launch vehicles, and ground systems. During the fiscal years 1995,
1994, and 1993, OCC purchased hardware and services totaling approximately
$4,477,000, $14,660,000 and $32,902,000, respectively, from Orbital.
 
     Pursuant to the ORBCOMM System Procurement Agreement (for the ORBCOMM Phase
1B System), ORBCOMM contracted with Orbital to procure additional communications
satellites and launch services. During the first six months of 1996, and during
fiscal year 1995, ORBCOMM purchased hardware and services totaling approximately
$28,031,000 (unaudited) and $23,672,000, respectively, from Orbital.
 
   
     In 1995, pursuant to the terms of the ORBCOMM System Design, Development
and Operation Agreement between OCC and ORBCOMM, ORBCOMM reimbursed OCC for
previous costs incurred in obtaining the FCC License and related costs. Such
costs and reimbursements were reported as revenues and expenses in the period
incurred.
    
 
     OCC procured U.S. Marketing Services from ORBCOMM USA on a cost
reimbursable basis. During the first six months of 1995 (unaudited) and the
fiscal years 1995, 1994, and 1993, OCC purchased marketing services totaling
approximately $886,000, $1,360,000, $2,093,000 and $749,000, respectively. OCC
ceased procuring U.S. Marketing Services from ORBCOMM USA at the end of
September 1995.
 
     OCC obtains virtually all of its funding for operations and for its capital
investments in ORBCOMM from Orbital via a non-interest bearing intercompany
borrowing agreement. As of June 30, 1996 (unaudited) and December 31, 1995 and
1994, OCC owed Orbital $70,290,402, $62,858,000, and $61,386,000, respectively,
none of which is currently payable.
 
     ORBCOMM USA currently obtains all of its funding from ORBCOMM via a
non-interest bearing intercompany borrowing agreement. As of June 30, 1996
(unaudited) and December 31, 1995 and 1994, ORBCOMM USA owed ORBCOMM $2,102,000,
$661,000, and $0, respectively, none of which is currently due.
 
     As of June 30, 1996 (unaudited), OCC owes $112,000 and $6,600 to ORBCOMM
and ORBCOMM International, respectively, for employee bonus payments paid on
behalf of OCC for employees previously employed by OCC (none for the years ended
December 31, 1995 and 1994).

(6)  INCOME TAXES
 
     OCC had no current or deferred provision for income taxes for the years
ended December 31, 1995, 1994, and 1993. The primary difference between pre-tax
financial statement income and taxable income in 1993 relates to the utilization
of net operating losses generated in 1992. There are no significant differences
between pre-tax financial statement income and taxable income in 1995 and 1994.
 
     The differences between the actual taxes and taxes computed at the U.S.
Federal income tax rate of 34% are summarized as follows:

(7)  STOCK OPTION PLAN
 
     OCC adopted a stock option plan in 1992 (the "ORBCOMM Plan"). The ORBCOMM
Plan provides for grants of incentive and non-qualified stock options to
purchase OCC common stock to officers and employees of OCC, ORBCOMM, ORBCOMM
USA, ORBCOMM International, and Orbital. Under the terms of the ORBCOMM Plan,
incentive stock options may not be granted at less than 100% of the fair market
value at the date of grant and non-qualified options may not be granted at less
than 85% of the fair market value of OCC common stock at the date of grant as
determined by a committee consisting of two OCC Board members and two members

     OCC recorded compensation expense related to the ORBCOMM Plan of
approximately $32,000, $47,000, and $50,000 for the years ended December 31,
1995, 1994, and 1993, respectively. In 1995, the Financial Accounting Standards
Board issued Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" ("SFAS 123"), which is effective for OCC's year
ending December 31, 1996. SFAS 123 recommends, but does not require, the
adoption of fair value accounting for stock-based compensation, including common
stock options issued to employees. OCC does not currently intend to adopt fair
value accounting for stock-based compensation issued to employees as recommended
by SFAS 123.
 
(8)  SUBSEQUENT EVENTS
 
   
     In August 1996, ORBCOMM and ORBCOMM Global Capital Corp. (the "Issuers")
issued $170,000,000 of Senior Notes due in 2004 with Revenue Participation
Interest (the "Old Notes"). Revenue Participation Interest represents an
aggregate amount equal to 5.0% of the ORBCOMM System revenue and is payable on
the Notes on each interest payment date subject to certain covenant
restrictions. Interest on the Old Notes will accrue at a rate of 14% per annum
and will be payable semi-annually in arrears on February 15 and August 15 of
each year, commencing on February 15, 1997.
    
 
   
     The Old Notes are exchangeable for an equal principal amount of registered
14% Series B Senior Notes due 2004 with Revenue Participation Interest (the
"Exchange Notes"). The Exchange Notes are substantially identical in form and
term to the Old Notes except that the Exchange Notes have been registered under
the Securities Act of 1933, as amended, and do not bear legends restricting the
transfer thereof. The Exchange Notes and the Old Notes are collectively referred
to as the "Notes." The Notes are fully and unconditionally

guaranteed on a joint and several basis by OCC, Teleglobe Mobile, ORBCOMM USA,
and ORBCOMM International (each, a "Guarantor" and collectively, the
"Guarantors"), limited only to the extent necessary for each such guarantee to
not constitute a fraudulent conveyance under applicable law. The guarantee of
each Guarantor ranks pari passu in right of payment with all senior indebtedness
of such Guarantor and senior in right of payment to all indebtedness expressly
subordinated to the guarantee of such Guarantor. The guarantees are nonrecourse
to the shareholders and/or partners of each Guarantor and no shareholder or
partner of any Guarantor will have any liability for any claim under the Notes.
    
 
   
     Upon closing, ORBCOMM used a portion of the net proceeds from the sale of
the Old Notes to purchase a portfolio of United States government securities to
provide for payment in full of interest on the Notes through August 15, 1998
(estimated at approximately $44.8 million).

                                AUDITORS' REPORT
 
To the Partners of
  Teleglobe Mobile Partners
 
     We have audited the consolidated balance sheet of Teleglobe Mobile Partners
(a development stage enterprise) as at December 31, 1995 and 1994 and the
consolidated statements of income, partners' capital and changes in financial
position for the years then ended and for the period from July 21, 1993 (date of
inception) through December 31, 1993. These consolidated financial statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on the financial statements based on our audits.
 
     We conducted our audits in accordance with Canadian generally accepted
auditing standards. Those standards require that we plan and perform an audit to
obtain reasonable assurance whether the 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.
 
     In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Partnership as at December
31, 1995 and 1994 and the results of its operations and the changes in its
financial position for the years then ended and for the period from July 21,
1993 (date of inception) through December 31, 1993 in accordance with generally
accepted accounting principles in the United States of America.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (IN THOUSANDS OF U.S. DOLLARS)
 
(1)  GOVERNING STATUTES AND NATURE OF OPERATIONS
 
     Teleglobe Mobile Partners, a Delaware general partnership (the
"Partnership") was originally formed July 21, 1993, in accordance with the
provisions of the Delaware Uniform Partnership Law for purposes of being a
general and a limited partner in ORBCOMM Global, L.P. ("ORBCOMM Global" formerly
known as ORBCOMM Development Partners, L.P.), a Delaware limited partnership
providing international wireless data communications services. As well the
Partnership carries on marketing activities through its subsidiary, ORBCOMM
International Partners, L.P. ("ORBCOMM International"). As of June 29, 1994, the
original Partnership was amended and restated by admitting a new partner to the
Partnership. The Partnership's term commenced on June 29, 1994 and shall
terminate on December 31, 2015.
 
(2)  SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of presentation
 
     The Partnership holds a 50% participating interest in ORBCOMM Global, which
in turn holds a 98% non-controlling interest in ORBCOMM USA, L.P. and ORBCOMM
International, two other partnerships formed to market the ORBCOMM system.
 
     The Partnership also directly holds a 2% participating interest in ORBCOMM
International bringing its direct and indirect participation to 51%. Teleglobe
Mobile Partners controls the operations and financial affairs of ORBCOMM
International.
 
     The Partnership is in its development stage, devoting substantially all of
its efforts to establishing a new communications business through ORBCOMM
Global. Operations are expected to commence fully in 1997. The consolidated
financial statements of the Partnership are prepared on the accrual basis of
accounting, in conformity with generally accepted accounting principles in the
United States of America and, where applicable, are in general conformity with
practices prevailing in the telecommunications industry. They include the
accounts of the Partnership and its subsidiary, ORBCOMM International.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Joint venture investment
 
     The investment in ORBCOMM Global is accounted for using the equity method.
 
  Income taxes
 
     As a partnership, Federal and State income taxes are the direct
responsibility of each partner. Accordingly, no income taxes have been recorded
in the consolidated financial statements.

(5)  SUBSEQUENT EVENTS
 
   
     In August 1996, ORBCOMM Global and ORBCOMM Global Capital Corp., a wholly
owned subsidiary of ORBCOMM Global, (the "Issuers") issued $170,000 of Senior
Notes due in 2004 with Revenue Participation Interest (the "Old Notes"). Revenue
Participation Interest represents an aggregate amount equal to 5.0% of the
ORBCOMM System revenue and is payable on the Notes on each interest payment date
subject to certain covenant restrictions. Interest on the Old Notes will accrue
at a rate of 14% per annum and will be payable semi-annually in arrears on
February 15 and August 15 of each year, commencing on February 15, 1997.
    
 
   
     The Old Notes are exchangeable for an equal principal amount of registered
14% Series B Senior Notes due 2004 with Revenue Participation Interest (the
"Exchange Notes"). The Exchange Notes are substantially identical in form and
term to the Old Notes except that the Exchange Notes have been registered under
the Securities Act of 1933, as amended, and do not bear legends restricting the
transfer thereof. The Exchange Notes and the Old Notes are collectively referred
to as the "Notes." The Notes are fully and unconditionally guaranteed on a joint
and several basis by Teleglobe Mobile Partners, Orbital Communications
Corporation, a majority owned subsidiary of Orbital Sciences Corporation,
ORBCOMM USA, L.P. and ORBCOMM International (each, a "Guarantor" and
collectively, the "Guarantors"), limited only to the extent necessary for each
such guarantee to not constitute a fraudulent conveyance under applicable law.
The guarantee of each Guarantor ranks pari passu in right of payment with all
senior indebtedness of such Guarantor and senior in right of payment to all
indebtedness expressly subordinated to the guarantee of such Guarantor. The
guarantees are non-recourse to the shareholders and/or partners of each
Guarantor and no shareholder or partner of any Guarantor will have any liability
for any claim under the Notes.
    
 
   
     Upon closing, ORBCOMM Global used a portion of the net proceeds from the
sale of the Old Notes to purchase a portfolio of United States government
securities to provide for payment in full of interest on the Notes through
August 15, 1998 (estimated at approximately $44.8 million).

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Capital is a Delaware corporation and its Certificate of Incorporation and
Bylaws provide for indemnification of its officers and directors to the fullest
extent permitted by law. Section 102(b)(7) of the Delaware General Corporation
Law (the "DGCL") permits a corporation in its certificate of incorporation to
eliminate the liability of a corporation's directors to a corporation or its
stockholders, except for liabilities related to breach of duty of loyalty,
actions not in good faith and certain other liabilities.
 
     Section 145 of the DGCL provides for indemnification by a Delaware
corporation of its directors, officers, employees and agents in connection with
actions, suits or proceedings brought against them by a third party or in right
of the corporation, by reason of the fact that they were directors, officers,
employees or agents, against liabilities and expenses incurred in such action,
suit or proceeding.
 
     The ORBCOMM Global Partnership Agreement generally provides that the
General Partners and any of their officers, employees, partners or agents will
not be liable to ORBCOMM Global or to any limited partner for any act or
omission by such party pursuant to authority granted under the Partnership
Agreement except if such action or omission results from gross negligence,
willful misconduct or bad faith. The Partnership Agreement also provides for
indemnification of any General Partner and any of their officers, employees,
partners or agents from and against any and all claims or liabilities of any
nature whatsoever arising out of or in connection with any action taken or
omitted by such party pursuant to authority granted by the Partnership
Agreement, except where attributable to gross negligence, willful or wanton
misconduct or bad faith.

ITEM 22.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
registrant undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
     The registrant undertakes that every prospectus: (i) that is filed pursuant
to the immediately preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act of 1933, and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
   
     The undersigned registrant hereby undertakes:
    
 
   
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement;
    
 
   
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
    
 
   
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective Registration Statement.
    
 
   
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
    
 
   
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
    
 
   
          (4) If the registrant is a foreign private issuer, to file a
     post-effective amendment to the Registration Statement to include any
     financial statements required by Rule 3-19 of Regulation S-K at the start
     of any delayed offering or throughout a continuous offering. Financial
     statements and information otherwise required by Section 10(a)(3) of the
     Act need not be furnished, provided, that the registrant includes in the
     prospectus, by means of a post-effective amendment, financial statements
     required pursuant to this paragraph (a)(4) and other information necessary
     to ensure that all other information in the prospectus is at least as
     current as the date of those financial statements. Notwithstanding the
     foregoing, with respect
    
 
                                      II-3
<PAGE>   185
 
   
     to registration statements on Form F-3, a post-effective amendment need not
     be filed to include financial statements and information required by
     Section 10(a)(3) of the Act of Rule 3-19 of Regulation S-K if such
     financial statements and information are contained in periodic reports
     filed with or furnished to the Commission by the registrant pursuant to
     Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
     incorporated by reference in the Form F-3.
    
 
   
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant 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 registrant 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 whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Ladies and Gentlemen:

                 In connection with the registration of $170,000,000 aggregate
principal amount of 14% Series B Senior Notes due 2004 (the "Securities") by
ORBCOMM Global, L.P., a Delaware limited partnership (the "Company") and
ORBCOMM Global Capital Corp., a Delaware corporation (together with the
Company, the "Issuers") and the guarantees of the Securities by Orbital 
Communications Corporation, a Delaware corporation, Teleglobe Mobile Partners, 
a Delaware general partnership, ORBCOMM USA, L.P., a Delaware limited
partnership and ORBCOMM International Partners, L.P., a Delaware limited
partnership (collectively, the "Guarantors"), under the Securities Act of 1933,
as amended, on Form S-4 filed with the Securities and Exchange Commission (the 
"Commission") on August 30, 1996, as amended by Amendment No. 1 filed with the 
Commission on October 21, 1996 (collectively, the "Registration Statement"), 
you have requested our opinion with respect to the matters set forth below.

                 In our capacity as your counsel in connection with such
registration, we are familiar with the proceedings taken and proposed to be
taken by the Issuers in connection with the authorization and issuance of the 
Securities, and, for the purposes of this opinion, have assumed such
proceedings will be timely completed in the manner presently proposed.  In

including an examination of originals or copies certified or otherwise
identified to our satisfaction of such documents, corporate records and

                 In our examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, and
the conformity to authentic original documents of all documents submitted to us
as copies.

                 We are opining herein as to the effect on the subject
transaction only of the internal laws of the State of New York, General 
Corporation Law of the State of Delaware and the Delaware Revised Uniform
Limited Partnership Act, and  we express no opinion with respect to the
applicability thereto, or the effect thereon, of the laws of any other
jurisdiction or, in the case of Delaware, any other laws, or as to any matters
of municipal law or the laws of any other local agencies within the state.

                 Capitalized terms used herein without definition have the
meanings ascribed to them in the Registration Statement.

                 Subject to the foregoing and the other matters set forth
herein, it is our opinion that as of the date hereof,

                 The Securities have been duly authorized by all necessary
partnership and corporate action of the Issuers, and when executed,
authenticated and delivered by or on behalf of the Issuers against payment
therefor in accordance with the terms of the Indenture, will constitute legally
valid and binding obligations of the Issuers, enforceable against the Issuers
in accordance with their terms.                                            

                 The opinions rendered above relating to the enforceability of 
the Securities are subject to the following exceptions, limitations and 
qualifications:  (i) the effect of bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to or
affecting the rights and remedies of creditors; (ii) the effect of general
principles of equity, whether enforcement is considered in a proceeding in
equity or law, and the discretion of the court before which any proceeding
thereof may be brought; and (iii) we express no opinion concerning the
enforceability of the waiver of rights or defenses contained in the Indenture.

          To the extent that the obligations of the Issuers and the Guarantors
under the Indenture may be dependent upon such matters, we assume for purposes
of this opinion that the Trustee is duly organized, validly existing and in
good standing under the laws of its jurisdiction of organization; that the
Trustee is duly qualified to engage in the activities contemplated by the
Indenture; that the Indenture has been duly authorized, executed and delivered
by the Trustee and constitutes the legally valid, binding and enforceable
obligation of the Trustee enforceable against the Trustee in accordance with
its terms; that the Trustee is in compliance, generally and with respect to
acting as a trustee under the Indenture, with all applicable laws and
regulations; and that the Trustee has the requisite organizational and legal
power and authority to perform its obligations under the Indenture.

          We consent to your filing this opinion as an exhibit to the
Registration Statement and to the reference to our firm contained under the
heading "Legal Matters."

consequences of the exchange of 14% Series B Senior Notes due 2004 of ORBCOMM
Global, L.P. and ORBCOMM Global Capital Corp. (together, the "Issuers"), which
have been registered under the Securities Act of 1933, as amended, for
outstanding 14% Senior Notes due 2004 of the Issuers, in connection with the
Registration Statement on Form S-4 filed with the Securities and Exchange
Commission (the "Commission") on August 30, 1996, as amended by Amendment No. 1
filed with the Commission on October 18, 1996 (collectively, the "Registration

                 (including Launch Vehicle Launch Services)

</TABLE>

         Section 3.3 - Adjustment to the Option Prices.  The Option Prices, or
any of them, as the case may be, will be subject to annual retroactive
adjustments for inflation based upon changes to the Gross National Product
implicit price deflator index as reported by the United States Department of
Commerce, Bureau of Economic Analysis on or after December of each calendar
year (the "CURRENT INDEX").  The Gross National Product implicit price deflator
index value of [CONFIDENTIAL TREATMENT] shall be used as the baseline index
against which all such annually reported index values are compared.   In the
event the differences between the current index value for the year then being
considered, and the baseline index value of [CONFIDENTIAL TREATMENT] exceeds
[CONFIDENTIAL TREATMENT] percent ([CONFIDENTIAL TREATMENT]%) per year, then the
monthly and milestone payments for those invoices or milestones scheduled to
have been






                                       5
<PAGE>   6


submitted or completed, as the case may be, during the year then being
considered, shall be increased by the difference (expressed as a percentage)
above the [CONFIDENTIAL TREATMENT]% annual inflation already included in the
milestone prices.  This calculation is shown by formula 1 below.  In the event
the difference between the current index value for the year then being
considered, and the baseline index value is less than [CONFIDENTIAL TREATMENT]
percent ([CONFIDENTIAL TREATMENT]%) per year, then the monthly and milestone
payments for those invoices or milestones scheduled to have been submitted or
completed, as the case may be, during the year then being considered, shall be
reduced by the difference (expressed as a percentage) below the [CONFIDENTIAL
TREATMENT]% annual inflation included in the milestone prices.  This
calculation is shown by formula 2 below.

         Formula 1:   Percentage Increase = (A / [CONFIDENTIAL TREATMENT]) - B
                                            ----------------------------------
                                                             B

         Formula 2:   Percentage Increase = B - (A / [CONFIDENTIAL TREATMENT])
                                            ----------------------------------
                                                             B

         A =     The current index value for the year then being considered.

         B =     For adjustments to invoices or milestones scheduled to be
                 submitted or completed in 1995, as the case may be, this
                 number is [CONFIDENTIAL TREATMENT] (for 1996 it is
                 [CONFIDENTIAL TREATMENT]; for 1997 it is [CONFIDENTIAL
                 TREATMENT]; for 1998 it is [CONFIDENTIAL TREATMENT]; for
                 subsequent years, continue to multiply the prior year's number
                 by [CONFIDENTIAL TREATMENT] per year).

         Section 3.4 - Taxes.  (a)  The Price does not include any federal,
state or local sales, use or excise taxes levied upon or measured by the sale,
the sales price, or the use of the items to be delivered or services required
to be performed hereunder.  Orbital shall list separately on its invoice any
such tax lawfully applicable to the items to be delivered or services required
to be performed hereunder and payable by  ORBCOMM Global.  The Price shall not
however include any taxes on property owned by the United States Government, or
any U.S. or foreign federal, state or local income taxes imposed on Orbital.

         (b)     In cases where Orbital and/or ORBCOMM Global are wholly or
partially exempt from such taxes and duties or otherwise entitled to relief by
way of protest, refund claims, litigation or other proceedings, Orbital shall
take all necessary steps to facilitate such exemption or relief by:

         (i)     Using reasonable efforts to bring about the exemption or
         relief before submitting the invoices to ORBCOMM Global; and

         (ii)    Complying with all formalities necessary to enable ORBCOMM
         Global to claim reimbursement with respect to taxes and duties that
         have been paid.  For this purpose,





                                       6
<PAGE>   7


         Orbital shall comply with the reasonable instructions given to it by
         ORBCOMM Global and provide in due time the information that ORBCOMM
         Global reasonably requires.

If any such tax is determined to be legally due from either Orbital or ORBCOMM
Global, ORBCOMM Global shall pay it separately.  ORBCOMM Global shall pay, or
reimburse Orbital for all out-of-pocket expenses incurred in connection with
the activities contemplated by this Subsection 3.4(b).


         Section 3.5 - Insurance.  The Price does not include the cost of
launch or Satellite insurance (but includes Satellite on-ground transportation
insurance and property insurance for the pre-launch phase), which insurance
shall be procured by ORBCOMM Global or, at ORBCOMM Global's discretion, by
Orbital for ORBCOMM Global's account.  ORBCOMM Global shall pay or promptly
reimburse Orbital for all expenses incurred by Orbital, on behalf of ORBCOMM
Global in obtaining launch and/or Satellite insurance, upon receipt of
Orbital's invoice therefor.


                    ARTICLE 4 - PAYMENT TERMS AND INVOICING

         Section 4.1 - Payment Terms and Invoices.  The Price for the Work
under this Agreement shall be invoiced and paid as follows:

         (a)     Initial Invoicing.  Upon the execution of this Agreement,
Orbital shall be entitled to invoice ORBCOMM Global an amount of $[CONFIDENTIAL
TREATMENT] for the Work performed prior to the date hereof, such invoice to be
paid by ORBCOMM Global within one (1) business day.

         (b)     Monthly Invoicing.  Orbital shall invoice ORBCOMM Global on a
monthly basis for a maximum of 90% of its costs incurred during such month
plus, to the extent permitted by Subsection 4.1(f), such portion of the cost in
excess of the maximum amount to be invoiced to ORBCOMM Global in accordance
with such  Subsection 4.1(f) and not previously invoiced and paid.  Orbital
shall present its invoice to ORBCOMM Global promptly after the end of the month
covered by the invoice.

         (c)     Category B Milestones.  The remaining 10% of costs incurred in
any month may be invoiced incrementally upon completion of the Category B
Milestone for that month as set forth in Exhibit B.

         (d)     Category A Milestones.  The balance of the price
($[CONFIDENTIAL TREATMENT]) is allocated to Category A Milestones as set forth
in Exhibit C.  The amount for such Category A Milestones may be invoiced upon
achievement of the relevant Category A Milestone in






                                       7
<PAGE>   8


accordance with the requirements for achievement of Category A Milestones set
forth in Section 4.2 below (the "CATEGORY A MILESTONE ACHIEVEMENT CRITERIA").

         (e)     The total amount paid under 4.1(a), (b) and (c) shall not
exceed $[CONFIDENTIAL TREATMENT].  In the event costs incurred are less than
$[CONFIDENTIAL TREATMENT], the remaining amount shall be paid pro-rata upon
each launch.

         (f)     Schedule 4.1(f) sets forth the maximum cumulative payments to
be made by ORBCOMM Global under Sections 4.1(a), (b) and (c) during the term of
this Agreement.  At any time during the term of this Agreement, ORBCOMM Global
shall not be obligated to make any payments associated with monthly invoices
and Category B Milestones to the extent that the cumulative costs exceed the
maximum payments identified in Schedule 4.1(f) at the relevant time until such
time where the cumulative costs are less than such maximum cumulative payments.

         Section 4.2 - Category A Milestone Achievement.  (a)  Preliminary
Design Review, Critical Design Review and System Production Readiness Review
shall be deemed achieved upon conduct of the respective review meaningfully
addressing all significant areas as described in the Statement of Work, mutual
agreement on the scope of and schedule for action plan items and resolution of
any action items mutually agreed to be resolved as a condition of the related
Category A Milestone achievement.  First Article Test shall be deemed achieved
upon successful completion of the First Article Acceptance Test Procedure.  In
the event of substantial achievement of any milestone, Orbital shall be
entitled to invoice for a portion of the value with the balance to be invoiced
upon full achievement or waiver.  In such event, any amount withheld shall be
at ORBCOMM Global's discretion, but shall be commensurate with the remaining
tasks and risks.  Preliminary Design Review, Critical Design Review and System
Production Readiness Review shall be deemed fully achieved no later than the
first launch.  In the event First Article Test is not fully achieved prior to
launch any remaining amount shall be earned to the same extent of On-orbit
Check Out achievement.

         (b)     Launch success for each launch service shall be deemed
achieved upon delivery of the Satellites to orbit in accordance with the orbit
criteria contained in Section 3.1.1 of the Launch Vehicle Statement of Work and
Specifications, as further defined in the interface control document for the
interface specification between the Launch Vehicle and the Satellite, which
interface control document shall be mutually agreed upon by Orbital and ORBCOMM
Global.  In the event the Section 3.1.1 criteria are not achieved, but the
Satellites are placed in an orbit that make them useable to ORBCOMM Global,
Orbital shall be entitled to payment for partial launch success in an amount to
be determined by negotiation of the parties based on the usability of the
Satellites to generate revenues.

         (c) On-Orbit Check Out for each plane of Satellites shall be deemed
achieved on a percentage basis as described in Schedule 4.2(c).  In the event
of a failure of Satellite operation due to launch failure, the On-orbit Check
Out Milestone payment may be earned for On-orbit Check Out of the fourth plane
in accordance with the criteria described in Schedule 4.2.  In the





                                       8
<PAGE>   9


event of failure or performance degradation below the criteria in Schedule 4.2
of any Satellite due to improper operation by ORBCOMM Global (to the extent
that such improper operation is not the result of Orbital's directives), such
Satellite shall be deemed fully functional for the purposes of On-orbit Check
Out Milestone achievement

         Section 4.3 - Achievement of Milestones.  (a) In the event that
Orbital fails to achieve any Category A Milestone in accordance with the
Category A Milestone Achievement Criteria on or before the scheduled completion
date shown in Exhibit C, ORBCOMM Global shall be relieved of its obligation to
pay the applicable amounts specified for such Category A Milestone until such
time as Orbital achieves such Category A Milestone in accordance with the
Category A Milestone Achievement Criteria or obtains a waiver in writing from
ORBCOMM Global for such achievement.  The invoicing and payment procedure
referred to Section 4.1 shall then apply mutatis mutandis.  This, together with
any additional rights and remedies ORBCOMM Global may have under Article 12 -
Termination, shall constitute ORBCOMM Global's exclusive right and remedy for
Orbital's failure to achieve any or all such Category A Milestones.  Orbital's
failure to timely complete any milestone shall not relieve ORBCOMM Global from
its obligation to pay for other achieved milestones.

         (b)     If ORBCOMM Global concludes that the milestone event for which
any invoices have been submitted has not been successfully completed in
accordance with the requirements of this Agreement or that any condition
established by this Agreement as prerequisite to payment has not been
fulfilled, it shall provide Orbital written exceptions within ten (10) business
days after receipt of the invoice, specifying in detail the non-conformance.
The applicable payments shall be made within five (5) business days after
ORBCOMM Global's receipt of Orbital's response, in writing, addressing in
detail each of ORBCOMM Global's exceptions and, in the event of any Category A
Milestone, demonstrating to the reasonable satisfaction of ORBCOMM Global that
the milestone requirements have been successfully completed; provided, however,
if, with respect to  any such Category A Milestone, ORBCOMM Global reasonably
concludes that Orbital's response to ORBCOMM Global's exceptions to be
non-responsive and so notifies Orbital as provided in Subsection 4.3(c) below,
ORBCOMM Global may, at its sole discretion, defer any unpaid amount of the
relevant Category A Milestone payment until the resolution of the matter as
described in Subsection 4.3(c) below.

non-responsive to ORBCOMM Global's exception to a Category A Milestone, ORBCOMM
Global shall notify Orbital thereof in writing (the "EXCEPTION NOTIFICATION")
within ten (10) business days after receipt of Orbital's response to ORBCOMM
Global's written exception.  The Exception Notification shall (i) specify in
detail the reason(s) ORBCOMM Global believes Orbital's response to be
non-responsive, and (ii) advise Orbital formally that ORBCOMM Global intends to
withhold payment for such Category A Milestones until Orbital demonstrates to
the reasonable satisfaction of ORBCOMM Global that such Category A Milestone
has been achieved in accordance with the Category A Milestone Achievement
Criteria.

         Section 4.5 - Auditor Review of Submitted Invoices.  Under this
Agreement, Orbital shall submit certified invoices on a monthly basis for a
percentage of incurred costs, and in certain cases for a percentage of incurred
costs but only after successful completion of any Category B milestones.  In
order to ensure ORBCOMM Global that the invoices that are submitted accurately
reflect (i) the actual incurred costs and (ii) the correct percentage of costs
to be invoiced under the terms of this Agreement, an outside auditor firm
selected by ORBCOMM Global may review the accuracy of submitted invoices under
this Agreement against Orbital's accounting books and records.  In the event
that an error was made and ORBCOMM Global was overcharged, the amount of the
overcharge shall be determined by the  auditors and the overcharged amount,
plus interest to be calculated at the prime rate of Morgan Guaranty Trust
Company of New York in effect on the first business day for each relevant month
from the date of overpayment, shall be refunded to ORBCOMM Global within five
(5) business days from the date of notification by the auditors.  All expenses
of such audits shall be paid by ORBCOMM Global except that, to the extent that
there is an overcharge greater than Fifty Thousand Dollars ($50,000) finally
determined and that such determination is binding upon the parties, Orbital
shall pay audit expenses with respect to any invoices for which an overcharge
is so determined.  To the extent that Orbital does not agree with the auditors'
determination, such dispute shall be settled in accordance with Section 16.4.

thirty (30) days of the implementation of the modification such unpaid portion
of the On-orbit Performance Incentive Payment.

                       ARTICLE 14 - ON-ORBIT PERFORMANCE
                               INCENTIVE PAYMENTS

         (a)     In addition to the Price set forth in Article 3 hereof,
Orbital shall be entitled to receive on-orbit performance incentive payments
during the On-orbit Performance Incentive Period.  Payments shall be made on a
per plane basis with the incentive to be earned on a monthly basis, for each
complete month during the first thirty (30) months years that there are at
least seven (7) Working Satellites in the plane, and during the last thirty
(30) months, for each complete month that there are at least six (6) Working
Satellites in the plane, as described in Schedule 14.

         (b)     The "ON-ORBIT PERFORMANCE INCENTIVE PERIOD" for each plane of
satellites shall commence on the first day after all the conditions for the
successful completion of the Category A Milestone attached to such plane have
been satisfied or when On-orbit Check Out is completed and reasonable
corrective actions mutually agreed upon by Orbital and ORBCOMM Global, if
necessary, have been implemented to the reasonable satisfaction of ORBCOMM
Global and shall continue for a period of five (5) years thereafter.

         (c)     The monthly On-orbit performance incentive payment to be
earned for each complete month during the On-orbit Performance Incentive Period
shall be as follows:

<TABLE>

</TABLE>




         (d)     In the event any available On-orbit Performance Incentive
Payment is not earned, the balance (up to a maximum of $[CONFIDENTIAL
TREATMENT] per plane) shall be available to be earned if there are at least six
(6) Working Satellites in any plane in the sixth year of operation payable on a
monthly basis over that year.

         (e)     In the event of failure or performance degradation of any
Satellite due to improper operation by ORBCOMM Global (to the extent that such
improper operation is not the result of Orbital's directives), or if any
Working Satellite is intentionally put out of service by ORBCOMM Global, it
shall, for the purpose of earning On-orbit Performance Incentive Payment, be
considered a Working Satellite.

         (f)     In the event of launch failure of any plane of Satellites, no
On-orbit Performance Incentive Payment shall be payable for that plane, but
shall be available to be earned for performance of the fourth plane, if
launched.


          ARTICLE 15 - SPECIAL PROVISIONS RELATING TO LAUNCH SERVICES

         Section 15.2 - Cross-Waiver of Liability Relating to the Launch of the
Orbital Satellites. (a)  In accordance with the applicable Department of
Transportation commercial launch license requirements, ORBCOMM Global agrees to
enter into an agreement with Orbital for a no-fault, no-subrogation,
inter-participant waiver of liability pursuant to which each shall not bring a
claim against or sue the employees of the other, or any of them, or the United
States Government, and each party agrees to be responsible for and to absorb
the financial and any other consequences of any Property Damage it incurs or
for any Bodily Injury to, or Property Damage incurred by, its own employees
resulting from activities carried out under this Agreement, irrespective of
whether such Bodily Injury or Property Damage is caused by ORBCOMM Global,
Orbital or by their contractors, subcontractors, officers, directors, agents,
servants and employees and the Government and regardless of whether such Bodily
Injury or Property Damage arises through negligence or otherwise.

         (b)     ORBCOMM Global and Orbital shall each be responsible for such
insurance as they deem necessary to protect their respective property.  Any
insurance carried in accordance with this Article 15 and any policy taken out
in substitution or replacement for any such policy shall provide that the
insurers shall waive any rights of subrogation against ORBCOMM Global, Orbital,
and the United States Government, as the case may be, and their contractors and
subcontractors at every tier.

         (c)     ORBCOMM Global and Orbital hereby agree to obtain a similar
waiver in the form set forth above from any party with which it enters into an
agreement relating to the activities (launch of the Satellites) contemplated by
this Article, including without limitation, all of its respective contractors,
subcontractors and suppliers at every tier, and all persons and entities to
whom it assigns all or any part of its rights or obligations under this
Agreement.

         (d)     As used herein, "BODILY INJURY" means bodily injury, sickness,
disease, disability, shock, mental anguish or mental injury sustained by any
person including death and damages for care and loss of services resulting
therefrom.  "PROPERTY DAMAGE" means injury to or destruction of tangible
property including the loss of use of such injured or destroyed property.

         Section 15.3 - Flight Readiness Assessment.  Orbital shall conduct a
Mission Readiness Review (MRR) to be held subsequent to Orbital's final launch
readiness review.  At the MRR, Orbital shall summarize the status of its
expendable launch vehicle (ELV) and launch support systems and attest to its
readiness to launch the mission.  If after due consideration of the status of
the ELV, spacecraft, and other launch support systems, ORBCOMM Global does not
agree





                                       22
<PAGE>   23


that the total mission is ready for launch, ORBCOMM Global shall retain the
right to direct the delay to the launch under the terms of the Changes
provision of this Agreement.

         Section 15.4 - Final Countdown Launch Authorization.  ORBCOMM Global
shall also be polled in the final countdown procedure during status checks and
shall retain the right to concur or not to concur in the "GO" for launch.
ORBCOMM Global's designated representative shall be authorized to make such a
decision.  If ORBCOMM Global does not concur, it may declare a "HOLD" and delay
the launch.  If ORBCOMM Global calls for delay and the cause for such delay
cannot be shown to be attributable to Orbital's performance, or to have been
within its control or due to its fault or negligence, Orbital shall receive an
equitable adjustment to the Agreement price and schedule.

         Section 15.5 - Range Support.  Orbital is responsible for the range
costs, interface, and all coordination with the Government Agencies that
control the launch ranges required to launch each payload.

panel.  Such appointments shall be made within ten (10) days of the receipt by
the appointing party of notice of the existence of such controversy or claim.
The unanimous decision and agreement of such panel shall resolve the
controversy or claim.  If the panel is unable to resolve such matter within
thirty (30) days of the submission of such controversy or claim to such panel,
it shall be brought before the Presidents of ORBCOMM Global and Orbital and a
designee of Teleglobe Mobile for final resolution.  If such individuals are
unable to resolve the matter within thirty (30) days of the submission of such
controversy or claim to such individuals by way of unanimous decision, either
party may remove the controversy or claim for arbitration in accordance with
Section 16.4(b).

         (b)     Any controversy or claim that is not resolved under Section
16.4(a) shall be settled by final and binding arbitration in New York, New
York, in accordance with the then existing United States domestic rules of the
American Arbitration Association (the "AAA") (to the extent not modified by
this Section 16.4).  In the event that claims or controversies arise under this
Agreement and any of the Definitive Agreements, such claims or controversies
may be consolidated in a single arbitral proceeding.  The arbitral tribunal
shall be composed of three (3) arbitrators who are expert in satellite
communications systems and/or launch vehicles as may be appropriate depending
on the nature of the dispute.  Each of ORBCOMM Global and Orbital shall appoint
one (1) arbitrator.  If any party fails to appoint an arbitrator within thirty
(30) days from the date on which another party's request for arbitration has
been communicated to the first party, such appointment shall be made by the
AAA.  The two (2) arbitrators so appointed shall agree upon the third
arbitrator who shall act as chairman of the arbitral tribunal.  If the two (2)
appointed arbitrators fail to nominate a chairman within ten (10) days from the
date as of which both arbitrators shall have been appointed, such chairman
shall be selected by the AAA.  In all cases, the arbitrators shall be fluent in
English.  Judgment upon any award rendered by the arbitrators may be entered
into any court having jurisdiction or application may be made for judicial
acceptance of the award and an order of enforcement, as the case may be.  The
parties agree that if it becomes necessary for any party to enforce an arbitral
award by a legal action or additional arbitration or judicial methods, the
party against whom enforcement is sought shall pay all reasonable costs and
attorneys' fees incurred by the party seeking to enforce the award.

         Section 16.5 - Governing Law.  This Agreement shall be construed in
accordance with and governed by the laws of the Commonwealth of Virginia, USA,
without giving effect to the provisions, policies or principles thereof
relating to choice or conflict of laws.

         Section 16.6 - Binding Effect; Assignment.  This Agreement shall be
binding upon and shall inure to the benefit of the parties and their respective
successors and permitted assigns.  Neither this Agreement nor any interest or
obligations hereunder shall be assigned or transferred

         forth herein.  All costs of Quality Inspections shall be borne by
         ORBCOMM, provided that Licensee shall be responsible for the
         reasonable out-of-pocket costs associated with the assistance received
         by ORBCOMM from Licensee's personnel specified in clause (C) above;

                 (vi)           (A)  To the extent permitted by applicable law,
         during the term of this Agreement and only so long as such use is in
         accordance with the terms and conditions set forth herein, use the
         ORBCOMM logos and all ORBCOMM trademarks and service marks, which
         Licensee acknowledges are owned by ORBCOMM or its Affiliates, in
         Licensee's marketing and advertising for the Licensee System.  All
         such marketing and advertising that contains references to the ORBCOMM
         System, OCC, ORBCOMM Global or ORBCOMM shall be in accordance with the
         ORBCOMM Identity Manual, the current version of which is attached
         hereto as Attachment D and which may be modified by ORBCOMM after
         giving Licensee five business days prior written notice (the "ORBCOMM
         Identity Manual"), provided that, for a period of six months from the
         receipt of such notice, Licensee shall be entitled to continue to use
         all existing marketing materials that previously complied with the
         ORBCOMM Identify Manual.  Licensee shall be required to obtain the
         prior written consent of ORBCOMM for all such marketing or
         advertising; provided that if Licensee complies with the ORBCOMM
         Identity Manual, the advance written approval of ORBCOMM shall not be
         required. Licensee shall obtain all Permits from all applicable
         Governmental Authorities to use ORBCOMM logos, trademarks and service
         marks.  To the extent ORBCOMM or any of the other ORBCOMM Entities has
         not otherwise previously done so and to the extent permitted by law,,
         Licensee shall register such logos, trademarks and service marks in
         ORBCOMM Global's name for use by Licensee in the Territory.  Prior to
         registering such logos, trademarks and service marks in ORBCOMM
         Global's name, Licensee shall advise ORBCOMM of its intent to do so
         and of the out-of-pocket costs that it expects to incur.  Upon receipt
         of ORBCOMM's written consent, Licensee shall proceed with such
         registration and, upon completion of the process, shall be reimbursed
         by ORBCOMM for the actual out-of-pocket costs incurred by it up to an
         amount equal to its out-of-pocket cost estimate.  Any modification or
         partial use of the word "ORBCOMM" for a logo, trademark, service mark
         or trade name shall also require the prior written approval of
         ORBCOMM;

                 (B)  Cooperate with ORBCOMM in providing reasonable support
         and any information that may be required in the defense in the
         Territory of the ORBCOMM logo and all ORBCOMM trademarks and service
         marks as a result of their use pursuant to this Agreement; and

                 (C)  During the term of this Agreement and thereafter, not (x)
         engage in any activities or commit any acts that may, directly or
         indirectly, contest, dispute or otherwise impair ORBCOMM's or its
         Affiliates' right, title and interest in such logos,

         trademarks and service marks or (y) directly or indirectly, re-license
         use of the ORBCOMM logo or any ORBCOMM trademarks and service marks to
         any other person, other than with respect to any Reseller or its
         Agents or Subagents, without the express written consent of ORBCOMM;

                 (vii)          Pay to ORBCOMM the fees, costs and other
         payments set forth in this Agreement;

                 (viii)         Give ORBCOMM and its representatives reasonable
         access during normal business hours to Licensee's books, accounts,
         records, contracts and documents concerning the Licensee System and
         use of the ORBCOMM logos, trademarks and service marks for the purpose
         of determining compliance by Licensee with the terms of this
         Agreement;

                 (ix)           In addition to ORBCOMM's access and/or use of
         the ORBCOMM System in the Territory permitted by Section 2(a), permit
         ORBCOMM and/or its representatives or Affiliates, at their sole
         expense, to directly and electronically communicate with (A)
         Licensee's NCC for the purpose of assessing the number and types of
         Subscriber Communicators registered with the Licensee System and their
         usage and the amount of data relayed through any of the Satellites,
         (B) the Licensee System for the purpose of verifying the reported
         amount of the gross operating revenues as specified in Section 8 and
         assisting Licensee in the maintenance and repair of the Licensee
         System and (C) the Satellites through the Licensee System for the
         purposes of ascertaining a Satellite's state-of-health and sending
         commands to it;

                 (x)            Include provisions substantially identical to
         those set forth in Section 17 in its contracts or agreements with each
         of the distributors, Resellers and Subscribers for the Licensee
         System;

                 (xi)           Use the ORBCOMM System Software only to operate
         the Licensee System, and shall not copy or disclose, sell, distribute
         or re-license such software to any other person or entity or reverse
         engineer or compile or disassemble such software;

                 (xii)          Not discriminate against any Subscriber because
         such Subscriber purchased or obtained its Subscriber Communicator from
         one source versus another and not offer service to Subscribers, who
         buy or lease their Subscriber Communicators from Licensee or an
         Affiliate of Licensee, at a price that is lower than that at which
         similar ORBCOMM Services are offered to Subscribers who obtain their
         Subscriber Communicators from another source;

                 (xiii)         To the extent permitted by law and except as
         permitted in Section 10, not register Subscriber Communicators, the
         billing address for which is outside the Territory unless otherwise
         agreed to in advance in writing by ORBCOMM Global;

                 (xiv)          (A)  To the extent permitted by law, offer to
         provide service to any reseller that has been approved as an ORBCOMM
         Service reseller by ORBCOMM





                                     Page 8

         USA, at substantially the same rates, terms and conditions as it
         offers other, similar resellers of the ORBCOMM Services in the same
         country in the Territory, or if there are no similar resellers in such
         country, then at rates, terms and conditions that are commercially
         reasonable, so long as such reseller is not in default under its
         reseller agreement with ORBCOMM USA;

                 (B)  To the extent permitted by law, offer to provide service
         to any reseller that has been accredited as an approved ORBCOMM
         Service reseller by another ORBCOMM service licensee (outside the
         United States), at substantially the same rates, terms and conditions
         as it offers other, similar resellers of the ORBCOMM Services in the
         same country in the Territory, or if there are no similar resellers in
         such country, then at rates, terms and conditions that are
         commercially reasonable; provided, however, that in the event Licensee
         does not desire to provide service to any such Reseller, Licensee
         shall provide ORBCOMM with its reasons therefor and request that
         ORBCOMM review such reseller for the purpose of either approving or
         disapproving such reseller as an accredited ORBCOMM Service reseller.
         In the event such reseller is accredited as an approved ORBCOMM
         Service reseller by ORBCOMM, Licensee shall be required to offer to
         provide service to such reseller in accordance with this Section
         3(a)(xiv); provided that in determining whether to accredit such
         reseller as an approved ORBCOMM Service reseller for the Territory
         ORBCOMM shall take into account whether other ORBCOMM service
         licensees for which such reseller is an accredited reseller have a
         provision in their service license agreement substantially similar to
         the terms and conditions set forth in this Section 3(a)(xiv)(B).  If
         such reseller is not so accredited by ORBCOMM, Licensee shall be under
         no obligation to provide service to such reseller in accordance with
         this Section 3(a)(xiv)(B);

                 (xv)           Offer to provide in the Territory the full
         range of ORBCOMM Services that are described in the ORBCOMM Service
         Description, as it may be amended from time to time, the current
         version of which is attached hereto as Attachment E;

                 (xvi)          Promptly advise ORBCOMM in writing if Licensee
         or any of its Affiliates  acquires any ownership or other economic
         interest in a Reseller.  In such cases, ORBCOMM shall have the right
         to examine the terms and conditions of the Reseller Agreement for the
         purpose of determining whether such Reseller is being given any
         preferential treatment regarding, among other things, the price it
         pays for ORBCOMM Services.  If in ORBCOMM's sole opinion, such
         preferential treatment exists, then ORBCOMM shall have the right to
         require, in its sole discretion, either that such preferential
         treatment immediately cease or that Section 8 of this Agreement be
         amended as appropriate.  In addition, ORBCOMM shall have the right to
         make a retroactive adjustment to previously paid Satellite Usage Fees;

                 (xvii)         Prior to the commencement of the provision of
         ORBCOMM Services in the Territory and within 15 days after the end of
         each calendar quarter thereafter, submit to ORBCOMM in writing a full
         description of its prices and pricing strategy for the provision of
         ORBCOMM Services.  Such description shall also address the issues of
         competitive pricing in the Territory and demonstrate that the pricing
         strategy and the





                                     Page 9

         prices serve the purpose of maximizing revenues and of making
         efficient and appropriate use of the Satellites..

                 (xviii)        On the first anniversary of the commencement of
         the provision of ORBCOMM Services in the Territory, and annually
         thereafter, submit to ORBCOMM in writing an operations report of the
         usage of ORBCOMM Services in the Territory. Such report shall include
         an analysis of the statistical data on message lengths, message
         frequencies, time of day, day of week and seasonal usage for each
         service offering and market segment served by Licensee. If not written
         in the English language, such report shall be accompanied by a true
         and complete English translation thereof;

                 (xix)          Participate with ORBCOMM in the preparation of
         traffic forecasts;

                 (xx)           Send ORBCOMM written notice of when the
         Licensee System commences operation;

                 (xxi)          Pay all Canadian, provincial, federal, state,
         local and other taxes, including but not limited to sales, use, gross
         receipts, and excise taxes and withholding, that arise from the
         performance of its duties under this Agreement, including the payment
         of all fees and other amounts due and owing hereunder, and pay any and
         all import or customs duties, fees, taxes or other amounts imposed by
         any Governmental Authority in the Territory applicable to the purchase
         of the Ground Segment Hardware; and

                 (xxii)         Charge Resellers and Subscribers, if License
         provides services directly to Subscribers, a long message surcharge,
         the amount of which shall be at least [CONFIDENTIAL TREATMENT] (or its
         equivalent in Canadian dollars) for each message whose length is
         between [CONFIDENTIAL TREATMENT] and [CONFIDENTIAL TREATMENT] bytes,
         inclusive, and at least [CONFIDENTIAL TREATMENT] (or its equivalent in
         Canadian dollars) for each message whose length exceeds [CONFIDENTIAL
         TREATMENT] bytes.

                 (b)            Responsibilities of ORBCOMM.  ORBCOMM shall:

                 (i)            Cooperatively work with and encourage the
         manufacturers and suppliers of Subscriber Communicators to offer such
         Communicators within one year of the Effective Date for sale or lease
         in the Territory, either directly or through distributors, one of
         which may be Licensee;

                 (ii)           As soon as available , provide written
         acceptance test procedures and acceptance criteria for the Licensee
         System (the "Acceptance Specifications"), which criteria must be
         successfully met by the Licensee System prior to ORBCOMM authorizing
         Licensee to access the ORBCOMM System.  Such criteria shall be
         sufficient to ensure that all the features and functions of the
         Licensee System are operating properly and in a manner compatible with
         the ORBCOMM System;





                                    Page 10
<PAGE>   11
                 (iii)          Within six months of the order for the Initial
         Purchase equipment, provide written operating and maintenance manuals
         for the NCC and GESs to be located in the Territory;

                 (iv)           Assist Licensee in providing data relating to
         the ORBCOMM System required by any Governmental Authority in
         connection with Licensee obtaining any of the Permits if ORBCOMM
         determines that Licensee cannot reasonably provide such data itself;
         provided that written data that exists or that ORBCOMM can readily
         compile from existing data shall be provided at ORBCOMM's expense and
         other written data or any data required to be presented in person or
         orally shall be provided at Licensee's expense; and provided further
         that ORBCOMM shall not be required to disclose any such data unless
         ORBCOMM reasonably believes that such data will be maintained by the
         receiving party on a confidential basis;

                 (v)            Use commercially reasonable efforts to provide
         24-hour a day emergency technical advice concerning the operation,
         maintenance and repair of the Licensee System. Requests for emergency
         technical advice may be made by telephone or facsimile and the advice
         may be provided by ORBCOMM using such similar means, with all
         communications conducted in the English language; provided that if, in
         ORBCOMM's sole discretion, the nature of these requests or their
         frequency indicate that Licensee's operators or technicians are
         technically inadequate for their tasks, ORBCOMM may require that these
         employees be retrained (or, at Licensee's option, replaced) at
         Licensee's cost, or ORBCOMM may charge for this advice in accordance
         with Section 5; and provided further that, until three (3) months
         after the System Available Date, emergency technical advice shall only
         be available between the hours of 9:00 a.m. and 5:00 p.m. United
         States Eastern Standard Time (or United States Eastern Daylight Time
         as applicable) on regular business days;

                 (vi)           Implement advertising and other promotional
         programs for the ORBCOMM System, the scope and timing of which shall
         be in ORBCOMM's sole discretion;

                 (vii)          Provide the maintenance and support services
         described in Attachment F, for the ORBCOMM System Software;

                 (viii)         Obtain (A) all necessary Permits from all
         applicable Governmental Authorities needed for the export of the
         Ground Segment Hardware from the United States of America (or from
         such other country where the hardware is manufactured or sold) to the
         Territory and, to the extent necessary, the rendering of the Related
         Services or the Other Services in the Territory and (B) all necessary
         visas and work permits for its personnel who will be traveling in the
         Territory to perform any of the Related Services or Other Services;
         provided, however, that at ORBCOMM's request, Licensee shall assist
         ORBCOMM in obtaining such visas and work permits from the appropriate
         Governmental Authorities located in the Territory;





                                    Page 11
<PAGE>   12
                 (ix)           Provide Licensee with a written breakdown of
         prices charged for the Ground Segment Hardware and Related Services,
         in a form suitable for the determination of import duties and other
         taxes, if any, no later than one month after the orders by Licensee
         for such Ground Segment Hardware have been received by ORBCOMM; and

                 (x)            Cause ORBCOMM USA to offer to any of Licensee's
         Resellers rights substantially similar to those set forth in Section
         3(a)(xiv)(A) and use all good faith effort to cause all other ORBCOMM
         Service licensees to offer to any of Licensee's Resellers rights
         substantially similar to those set forth in Section 3(a)(xiv)(B).


SECTION 4 - GROUND SEGMENT HARDWARE

         (a)     Ground Segment Design.  To the fullest extent permitted by
law, the parties to this Agreement acknowledge and agree that the ground
segment hardware of the NCC and the GESs (the "Ground Segment Hardware") is
unique to the ORBCOMM System and has been designed to ensure that more than one
licensee can use the ORBCOMM System to provide ORBCOMM Services.  To the
fullest extent permitted by law, the parties further acknowledge and agree that
(i) it is critical that licensee systems not interfere with each other and (ii)
to ensure that mutually compatible operations can take place, it is essential
that Licensee purchase from ORBCOMM the Ground Segment Hardware to be used in
the Territory and that the Ground Segment Hardware be installed, integrated and
tested by ORBCOMM.

         (b)     Purchase and Sale of Ground Segment Hardware and Related
Services.

                 (i)            (A)  Licensee agrees to purchase from ORBCOMM,
         directly or through an Affiliate of ORBCOMM, and ORBCOMM agrees to
         sell to Licensee or to its wholly owned subsidiary, the Ground Segment
         Hardware and related construction, installation, integration, test and
         training services (the "Related Services") necessary to construct,
         install and operate the NCC and GES(s) in the Territory.  A list of
         the major components of the Ground Segment Hardware and a general
         description of the Related Services is contained in Attachment G to
         this Agreement.  Notwithstanding the foregoing, the parties agree that
         Licensee need not purchase all the Ground Segment Hardware for the
         specified NCC and GES(s) and the Related Services at the same time.
         The initial minimum purchase (the "Initial Purchase") shall be for the
         NCC and for [CONFIDENTIAL TREATMENT] single-antenna GES, and the
         Related Services associated with the construction, installation,
         integration, test and training associated with such hardware.  The
         order for the Initial Purchase shall be placed by Licensee before July
         1, 1996, and if not so placed, it shall be deemed to have been placed
         by Licensee and accepted by ORBCOMM on July 1, 1996.  Thereafter,
         Licensee shall purchase from ORBCOMM the Ground Segment Hardware and
         the Related Services for the additional GES sites, and the Ground
         Segment Hardware and the Related Services to upgrade any
         single-antenna GES to the dual-antenna configuration, such that all of
         the hardware required in Section 3(a)(i) is ordered within six months
         of the System Available Date.





                                    Page 12
<PAGE>   13
                 (B)  Notwithstanding the foregoing, the purchase of any part
         of the Ground Segment Hardware may be delayed if Licensee contracts
         with another ORBCOMM System licensee to share the use of such other
         licensee's ground segment hardware, so long as in ORBCOMM's sole
         opinion determined from time to time such use of such other ground
         segment hardware will not significantly degrade the quality of service
         in the Territory or in the territory of such other licensee.  Licensee
         shall immediately notify ORBCOMM of the occurrence of a default or an
         event of default under such agreement or the receipt of a notice of
         termination under such agreement. If such agreement is terminated,
         Licensee shall immediately place an order with ORBCOMM for the
         purchase of the necessary Ground Segment Hardware.  A copy of any such
         contract, with a certified translation into English, if necessary,
         shall be provided to ORBCOMM. ORBCOMM and Licensee acknowledge that
         they have concurrently herewith entered into a Ground Segment
         Facilities Use Agreement relating to the use by Licensee of the US
         Ground Segment Hardware as defined therein.  The parties agree that
         the responsibilities of Licensee under this Section 4 with respect to
         the purchase (and accordingly, the installation and maintenance) of
         the License System shall be deferred until the termination of the
         Ground Segment Facilities Use Agreement.

                 (ii)           Licensee shall acquire and make available for
         use, within six months of the placing any order for Ground Segment
         Hardware and the Related Services, certain land, buildings, utilities
         and facilities that are listed in Attachment H.  Licensee shall be
         responsible and shall arrange for import of the Ground Segment
         Hardware into the Territory and its shipment from the Point-of-Entry
         in the Territory to the installation sites.

                 (iii)          ORBCOMM shall provide all the Ground Segment
         Hardware and Related Services, other than those items listed in
         Attachment H, necessary to allow Licensee to commence operation of the
         Licensee System, including the performance of a System Acceptance Test
         to ensure and certify that the Licensee System is meeting the
         requirements of the Acceptance Specifications (the "System Acceptance
         Test").

         (c)     Consideration.  In consideration of ORBCOMM selling to
Licensee the Ground Segment Hardware and the Related Services, Licensee agrees
to pay the following amounts to ORBCOMM:

                 (i)            For the Initial Purchase, consisting of the
         Ground Segment Hardware and the Related Services for the NCC and for
         one GES, which will be in a single-antenna configuration,
         [CONFIDENTIAL TREATMENT];

                 (ii)           For subsequent purchases, [CONFIDENTIAL
         TREATMENT] for each single-antenna configured GES, plus [CONFIDENTIAL
         TREATMENT] for each dual-antenna configured GES, plus [CONFIDENTIAL
         TREATMENT] for each upgrade of an existing single-antenna GES from the
         single- to the dual-antenna configuration; and

         upgrade of the single-antenna GES to a dual-antenna configuration is
         placed at the same time, [CONFIDENTIAL TREATMENT].

         The prices set forth above shall remain in effect for orders placed on
         or before [CONFIDENTIAL TREATMENT].  For any orders placed during
         [CONFIDENTIAL TREATMENT], the prices set forth above shall be adjusted
         by an amount that is equitable and based on industry conditions,
         provided, however, that any increase shall not be more than
         [CONFIDENTIAL TREATMENT] percent.  For orders placed after 
         [CONFIDENTIAL TREATMENT], to the fullest extent provided by law,
         ORBCOMM reserves the right to set such prices as it, in its sole
         discretion, deems appropriate so long as such prices are [CONFIDENTIAL
         TREATMENT]. Any and all import or customs duties, fees, taxes or other
         amounts imposed by any Governmental Authority in the Territory
         applicable to the purchase of the Ground Segment Hardware shall be
         paid by Licensee and shall be in addition to the amounts set forth
         above.

         [CONFIDENTIAL TREATMENT] percent upon receipt by Licensee of a
         [CONFIDENTIAL TREATMENT] and (D) [CONFIDENTIAL TREATMENT] percent at
         [CONFIDENTIAL TREATMENT], however, that in the event it is not
         possible for any reason to [CONFIDENTIAL TREATMENT], the amount of the
         final payment shall be mutually agreed upon, taking into account the
         costs incurred by ORBCOMM and a reasonable profit on those costs; and
         provided, further that the first payment of [CONFIDENTIAL TREATMENT]
         for the Initial Purchase shall be refunded to Licensee only if this
         Agreement is terminated for any reason before the Initial Purchase
         order is placed or deemed to be placed.  In no other instance will
         ORBCOMM be obligated to refund the initial payment of [CONFIDENTIAL
         TREATMENT].

         (g)     Warranty.

                 (i)            Notwithstanding acceptance of delivery by
         Licensee of the Ground Segment Hardware as provided in Section 4(e)
         and subject to the warranty conditions in this Section 4(g), ORBCOMM
         hereby warrants that, for a period of [CONFIDENTIAL TREATMENT] after
         completion of the System Acceptance Test (the "Warranty Period"), the
         Ground Segment Hardware shall be free from defects in material and
         workmanship and shall operate and conform to the performance
         capabilities, specifications, functions and other descriptions set
         forth in the Acceptance Specifications.  ORBCOMM shall, at its
         expense, repair or replace any Ground Segment Hardware that does not
         conform to such warranty. ORBCOMM's obligation during the Warranty
         Period shall be limited to repair or replacement of any Ground Segment
         Hardware for which it has provided a warranty. Notice of all claimed
         defects must be provided in writing to ORBCOMM within the Warranty
         Period.  ORBCOMM shall determine to its satisfaction after inspection
         that the product or part was defective, and it shall determine where
         the repair shall take place. Any Ground Segment Hardware repaired or
         replaced shall be subject only to the original Warranty Period.  The
         warranty set forth herein is Licensee's exclusive remedy against
         ORBCOMM for any defective Ground Segment Hardware and is in lieu of
         all other warranties, express or implied.

                 (ii)           The warranty set forth herein shall not extend
         to any Ground Segment Hardware that, upon ORBCOMM's or its
         subcontractors' examination is found to have been (A) mishandled,
         misused or subject to negligence, accident or abuse by Licensee or its
         officers, employees, representatives, agents or consultants (other
         than ORBCOMM), (B) operated or maintained contrary to ORBCOMM's
         specifications or instructions or otherwise used improperly, (C)
         tampered with or damaged as evidenced by, for example, broken seals,
         unauthorized modifications, damaged packaging containers and the like,
         (D) repaired and/or altered by anyone other than ORBCOMM or its
         subcontractors without ORBCOMM's prior written approval or (E)
         delivered to ORBCOMM not in conformance with the notice requirements
         set forth herein.

         (h)     Ground Segment Hardware Changes.  ORBCOMM reserves the right
to change, in its sole discretion and on terms that are commercially
reasonable, any of the terms, conditions and provisions of this Section 4 that
it deems necessary if any applicable law in the Territory requires that (i)
ORBCOMM change the design of the Ground Segment Hardware or (ii) any elements
of the Ground Segment Hardware be procured in the Territory.

business in New York on the last business day of such calendar month. In
calculating the amount owed by Licensee hereunder, ORBCOMM shall take into
account any credits owed to Licensee pursuant to Section 10(d) .  In the event
that Licensee does not provide ORBCOMM with any of the foregoing information,
ORBCOMM may make its own estimate of the total gross operating revenues, which
estimate shall be binding on Licensee, and compute the amount to be invoiced
using such estimate.

         (ii)           Within [CONFIDENTIAL TREATMENT] of the receipt of the
Satellite Usage Fee invoice, Licensee shall pay the Satellite Usage Fee by
electronic fund transfer to the bank account specified by ORBCOMM. All

SECTION 9 - BILLING SOFTWARE

         To the fullest extent permitted by law, the parties to this Agreement
acknowledge and agree that it is critical that (i) in the universal
commissioning of new applications using the ORBCOMM System, Licensee and other
ORBCOMM System licensees have a billing system that can adequately and
appropriately bill Resellers and Subscribers for such applications and (ii)
Multinational Accounts be established.  Accordingly, Licensee acknowledges that
it is essential that Licensee obtain a license from CSC Intelicom, Inc.
("CSC") for the billing software (the "Billing Software") Licensee will use for
ORBCOMM Services using the





                                    Page 19
<PAGE>   20
Licensee System. Licensee hereby agrees to use its best efforts to obtain a
license for the Billing Software and purchase certain hardware from CSC on
mutually agreeable terms and conditions. Notwithstanding the foregoing, ORBCOMM
and Licensee acknowledge that they currently intend to enter into a Billing
Services Agreement relating to the performance by ORBCOMM USA of certain
billing services on behalf of Licensee on mutually agreeable terms and
conditions.  The parties agree that the responsibilities of Licensee under this
Section 9 with respect to the licensing of the Billing Software shall be
deferred until the earlier to occur of (a) the termination of the Ground
Segment Facilities Use Agreement (and the concurrent termination of the Billing
Services Agreement) and (b) the placement by Licensee of an order to purchase
the Ground Segment Hardware in accordance with Section 4(b).


SECTION 10 - MULTINATIONAL ACCOUNTS

         (a)            Definitions. The following terms shall have the
following meanings:

         an account pursuant to which a customer, who may be a reseller or
         other intermediary or an end-user (a "Multinational Account
         Customer"), accesses the ORBCOMM System, using some or all of its
         Subscriber Communicators, in more than one territory; such Subscriber
         Communicators may be permanently located in one specific territory, or
         they may be located in two or more territories and roam between such
         territories;

                        (ii)      A "Contracting Licensee" shall be defined as
         the ORBCOMM System licensee that has contracted with the Multinational
         Account Customer to provide such Customer with ORBCOMM Services, which
         Contracting Licensee shall be entitled to bill and collect from the
         Multinational Account Customer for all ORBCOMM Services, whether
         rendered in its territory or the territory of another ORBCOMM System
         licensee; and

                        (iii)     A "Servicing Licensee" shall be defined as an
         ORBCOMM System licensee that is providing ORBCOMM Services in its
         territory to a Multinational Account Customer of another ORBCOMM
         System licensee.  For purposes of this Section 10, ORBCOMM USA shall
         be deemed an ORBCOMM System licensee.

         (b)            Contracting Licensee.  Licensee shall be entitled to be
a Contracting Licensee, unless this right has been withdrawn by ORBCOMM in the
event of nonpayment of any amounts owed by the Contracting Licensee pursuant to
Section 10(d).  As a Contracting Licensee, Licensee shall advise ORBCOMM
promptly (i) of the identification of Subscriber Communicators that may be used
in territories other than the Territory, and those other territories in which
they may be used and (ii) when a Multinational Account has been terminated.
Upon receipt of the notice specified in clause (i) above, ORBCOMM shall attempt
to make arrangements with the appropriate Servicing Licensee(s) so that service
may be provided in such other territory to the Multinational Account Customer's
Subscriber Communicators within [CONFIDENTIAL TREATMENT] days of receipt by
ORBCOMM of such notice.  Upon receipt of the notice specified in clause (ii)
above, ORBCOMM shall attempt to





                                    Page 20

terminate the service arrangements for such Multinational Account Customer made
with any Servicing Licensee; provided that, until the earlier to occur of the
termination of such service arrangements and [CONFIDENTIAL TREATMENT] days
after receipt by the Servicing Licensee of notice from ORBCOMM of the
termination of such Multinational Account, the Contracting Licensee shall be
responsible for billing and collecting payments for services provided to the
Multinational Account Customer.  The Contracting Licensee agrees to register on
the Licensee System all Subscriber Communicators of any Multinational Account
Customer.

         (c)            Servicing Licensee.  To the extent permitted by laws,
rules and regulations in the Territory, Licensee shall be required to act as a
Servicing Licensee for a Multinational Account Customer when requested to do so
by ORBCOMM.  As a Servicing Licensee, Licensee shall (i) submit rated call
detail records to ORBCOMM for transmittal to the Contracting Licensee, for
activation on, access to and use of the Licensee System by a Multinational
Account Customer, at the same rates then being charged by Licensee to its
customers for similar services in the Territory, (ii) terminate a Multinational
Account Customer's access to and use of the Licensee System within
[CONFIDENTIAL TREATMENT] days of receipt of notice from ORBCOMM that such
Multinational Account has been terminated, and (iii) offer to Multinational

assistance services Licensee provides to its customers other than those
services associated with billing and collection functions.

         (d)            Payments.  Within [CONFIDENTIAL TREATMENT] days of the
end of each calendar month, a Servicing Licensee shall submit monthly invoices
to ORBCOMM, for transmittal to the Contracting Licensee, for activation on,

which invoices shall set forth the amount owed in the Servicing Licensee's
currency.  Within [CONFIDENTIAL TREATMENT] days after the end of each calendar
month, ORBCOMM shall calculate and notify Licensee of the net amount in U.S.
Dollars, (using the official exchange rates in effect at Morgan Guaranty Trust
Company of New York at the close of business in New York on the last business
day of the applicable calendar month), due to or from Licensee for
Multinational Account services, which amount shall be calculated based on the
invoices ORBCOMM has received from any Servicing Licensee for the preceding
calendar month.  In calculating amounts due hereunder, ORBCOMM shall be
entitled to add a surcharge to all amounts invoiced by a Servicing Licensee,
not exceeding [CONFIDENTIAL TREATMENT] percent of such invoiced amount, which
surcharge ORBCOMM shall be entitled to retain as payment for services rendered
by it pursuant to this Section 10.

         In the event Licensee owes a net amount calculated in accordance with
the foregoing, Licensee shall pay to ORBCOMM such amount within [CONFIDENTIAL
TREATMENT] days of receipt of notice from ORBCOMM of such calculation.  In the
event Licensee is owed a net amount calculated in accordance with the
foregoing, such net amount owed shall be offset first, against any amounts then
owing by Licensee as a Contracting Licensee or a Servicing Licensee and second,
against any Satellite Usage Fees then owed by Licensee to ORBCOMM, with the
balance payable by ORBCOMM to Licensee within [CONFIDENTIAL TREATMENT] days of
receipt by Licensee of such notice.

Acceptance Specifications, ORBCOMM shall be entitled, at its option, (i) to
require Licensee to perform a System Acceptance Test, (ii) to have such a test
performed by purchasing a Repeat Systems Acceptance Service as described in
Section 5(a) or (iii) to perform a System Acceptance Test itself.  If ORBCOMM
elects to require Licensee to take the action specified in either (i) or (ii)
above, ORBCOMM shall advise Licensee in writing of such election and Licensee
must perform, or have performed, the test within ten days thereafter. If
ORBCOMM elects to perform the System Acceptance Test itself, ORBCOMM shall
advise Licensee in writing of such election and Licensee shall provide ORBCOMM
and its representatives access to Licensee's facilities, including its
equipment.  The cost to perform the System Acceptance Test shall be borne
solely by Licensee unless, after completion of such test, ORBCOMM reasonably
concludes that the Licensee System is operating in accordance with the
Acceptance Test, in which case the cost thereof shall be borne by ORBCOMM.

         (b)            Corrective Action.  If ORBCOMM determines from the
System Acceptance Test that the Licensee System is not operating in accordance
with the Acceptance Specifications, ORBCOMM shall be entitled to require
Licensee immediately to cease operation of the Licensee System until ORBCOMM
determines that all necessary corrections have been made by Licensee. In the
event such corrections are not made within three months of receipt by Licensee
of written notice thereof, ORBCOMM shall be entitled to terminate this
Agreement.

         take any action that results in Licensee or ORBCOMM contravening or
         violating any law in effect in any part of the Territory, in any other
         territory in which Subscriber Communicators served by Licensee are

SECTION 13 - CHANGE OF CONTROL

         In the event a change in control as defined in Section 6(b)(ii) occurs

SECTION 16 - SYSTEM OUTAGES AND FAILURE

         (a)            In the event ORBCOMM is unable to provide Licensee with
access to the ORBCOMM System due to temporary or intermittent problems (not
including planned periods of satellite unavailability that result from the
system architecture) with the ORBCOMM System caused by any of the ORBCOMM
Entities (an "Intermittent Service Problem") for a total of more than ten full
days during any one year period commencing on the later to occur of the System
Available Date and the date the Licensee System commenced operations and any
anniversary of such date, Licensee's sole and exclusive remedy shall be to
extend the term of this Agreement [CONFIDENTIAL TREATMENT] day for each day or 
part of a day in excess of such ten full days that ORBCOMM is unable to provide
Licensee with access to the ORBCOMM System; provided, however that if the

ANY REPRESENTATIONS OR WARRANTIES WHATSOEVER WITH RESPECT TO THE ORBCOMM

OR ANY SERVICES AND/OR PRODUCTS TO BE PROVIDED UNDER THIS AGREEMENT.  TO THE
FULLEST EXTENT PERMITTED BY LAW, EACH OF THE ORBCOMM ENTITIES EXPRESSLY
DISCLAIMS, AND LICENSEE HEREBY EXPRESSLY WAIVES, RELEASES AND RENOUNCES ALL
OTHER WARRANTIES, OBLIGATIONS AND LIABILITIES OF EACH OF THE ORBCOMM ENTITIES,
EXPRESS OR IMPLIED, ARISING BY LAW OR





                                    Page 27
<PAGE>   28
OTHERWISE, WITH RESPECT TO, INCLUDING, BUT NOT LIMITED TO, (i) ANY IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; (ii) ANY
IMPLIED WARRANTY ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING OR USAGE
OF TRADE; (iii) ANY WARRANTIES AS TO THE ACCURACY, AVAILABILITY OR CONTENT OF

         (b)            Limitation of Liability.  (i)  Each of the parties
acknowledges and understands that the ORBCOMM System is a new, untested system
that entails a high degree of risk of (A) delay in or cancellation of
deployment and (B) launch vehicle, satellite and other equipment or software
failure or impaired performance, and that there can be no assurance that the
ORBCOMM System will be an economically viable system even if successfully
deployed. Each party shall bear all responsibility, risk and cost associated
with developing and maintaining its respective business, and none of the
ORBCOMM Entities shall be liable to Licensee for costs or damages caused by any
schedule delays or failure of the ORBCOMM System or any component thereof,
except as specifically provided in Section 16.

         (ii)           Licensee acknowledges that ORBCOMM shall supply the
service that is the subject of this Agreement on a good faith efforts basis and
that service failures and interruptions may occur and are difficult to assess
as to cause or resulting damages.  In such event and except as otherwise
provided in Section 16, the parties agree that the ORBCOMM Entities shall not
be liable to Licensee for any losses or damages arising out of any failure of
performance, error, omission, interruption, deletion, defect, delay in
operation or transmission, communications line failure, theft or destruction or
behavior, negligence, or under any other cause of action.

         (iii)          NOTWITHSTANDING ANYTHING CONTAINED HEREIN TO THE
CONTRARY, IN NO EVENT SHALL EITHER PARTY HAVE ANY OBLIGATION, LIABILITY, RIGHT,
CLAIM OR REMEDY TO THE OTHER UNDER THIS AGREEMENT FOR LOSS OF USE, REVENUE OR
PROFIT OR FOR ANY OTHER INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.  In
addition, in no event shall any liability of ORBCOMM or any of the other
ORBCOMM Entities exceed an amount equal to [CONFIDENTIAL TREATMENT],
[CONFIDENTIAL TREATMENT] and [CONFIDENTIAL TREATMENT] provided hereunder.

SECTION 18 - DISPUTE RESOLUTION

         (a)            Subject to the provisions of Section 20(n), in the
event of a dispute regarding any matter covered by this Agreement, ORBCOMM and
Licensee shall use all reasonable efforts to resolve such dispute within 60
calendar days of receipt by either party of notice of the existence of any such
dispute.  In the event the parties are unable to agree on the resolution of
such dispute within such period of time, either party may remove the dispute
for settlement by final and binding arbitration in New York, NY, in accordance
with the then existing United States domestic rules of the American Arbitration
Association ("AAA") (to the extent not modified by this Section).  In the event
that more than one dispute arises under this Agreement, such disputes may be
consolidated in a single arbitral proceeding.  The arbitral tribunal shall be
composed of three arbitrators.  Each of ORBCOMM and Licensee shall appoint one
arbitrator. If any party shall fail to appoint an arbitrator within 30 days
from the date on which the other party's request for arbitration has been
communicated to the first party, such appointment shall be made by the AAA. The
two arbitrators so appointed shall agree upon the third arbitrator who shall
act as chairman of the arbitral tribunal and who shall be an expert in the
satellite communications business.  If the two appointed arbitrators fail to
nominate a chairman within ten days from the date as of which both arbitrators
shall have been appointed, such chairman shall be selected by the AAA.  In all
cases, the arbitrators shall be fluent in English.  Judgment upon any award
rendered by the arbitrators may be entered in any court having jurisdiction or
application may be made for judicial acceptance of the award and an order of
enforcement, as the case may be.  The parties agree that if it becomes
necessary for any party to enforce an arbitral award by a legal action or
additional arbitration or judicial methods, the party against whom enforcement
is sought shall pay all reasonable costs and attorney's fees incurred by the
party seeking to enforce the award.

         (b)            Pending a final determination by the arbitrators, if
the dispute concerns the payment by Licensee of any fees or amounts due
hereunder (including the right to conduct an audit of such fees or amounts),
ORBCOMM shall have the right to terminate Licensee's access to the ORBCOMM
System and, in the event ORBCOMM elects to exercise such right and
notwithstanding any determination by the arbitrators, Licensee's sole remedy
for such termination by ORBCOMM shall be an extension of the term of this
Agreement equal to the period during which Licensee was denied access to the
ORBCOMM System.

         (c)            Except with respect to the application of Section 20(n)
hereof, the rights of the parties under this Section 18 shall be the exclusive
remedy with respect to any dispute regarding any matter covered by this
Agreement.


SECTION 19 - COMPLIANCE WITH LAWS

         The Licensee shall comply in all material respects with all applicable
laws, rules and regulations of any Governmental Authority in the performance of
its obligations hereunder. In particular, any export of ORBCOMM hardware,
software and data shall comply with applicable U.S. export control
requirements.  Licensee agrees to comply with all applicable laws of the United
States regarding export controls and foreign corrupt practices.  Summaries

binding upon the parties, their successors and permitted assigns.  Subject to
Section 13, neither this Agreement nor any interests or duties of Licensee

without the express written consent of ORBCOMM, which consent shall not be
unreasonably withheld.

         (c)            Entire Agreement.  This Agreement and all attachments
(which are hereby made part of this Agreement) contain the entire understanding
between Licensee and ORBCOMM and supersede all prior written and oral

         (d)            Governing Law and Jurisdiction.  (i)  The construction,
interpretation and performance of this Agreement, as well as the legal
relations of the parties arising hereunder, shall be governed by and construed
in accordance with the laws of the State of New York, without giving effect to
the conflict or choice of law provisions thereof.  The United Nations
Convention on Contracts for the International Sale of Goods (1980) shall not
apply to any provisions of this Agreement.  Neither party may bring any action
for a claim under this Agreement later than one year after the termination of
this Agreement; provided that claims under any provision of this Agreement that
survives termination of this Agreement may be brought within one year of the
later of the occurrence of the event giving rise to the claim and actual
knowledge thereof by the party asserting such claim.

         (ii)  For purposes of Section 20(n), Licensee by its execution hereof
(A) hereby irrevocably submits to the nonexclusive jurisdiction of the state
courts of the State of New York and to the nonexclusive jurisdiction of the
United States District Court for the Southern District of New York, for the
purpose of any suit, action or other proceeding arising out of or based upon
this Agreement or the subject matter hereof brought by ORBCOMM and (B) hereby
waives to the extent not prohibited by law, and agrees not to assert, by way of
motion, as a defense or otherwise, in any such proceeding, any claims that it
is not subject personally to the jurisdiction of the above-named courts, that
its property is exempt or immune from attachment or execution, that any such
proceeding brought in one of the above-named courts is improper, or that this
Agreement or the subject matter hereof may not be enforced in or by such court.
Licensee hereby consents to service of process in any such proceeding in any
manner permitted by the laws of the State of New York and agrees that service
of process by registered or certified mail, return receipt requested, at the
address specified in or pursuant to Section 20(a) hereof is reasonably
calculated to give actual notice.  Licensee agrees that at ORBCOMM's request it
will appoint an agent for service of process within the State of New York.

         (e)            Force Majeure.  Neither party shall be held responsible
for failure or delay in performance or delivery if such failure or delay is the
result of an act of God, the public enemy, embargo, governmental act, fire,
accident, war, riot, strikes, inclement weather or other cause of a similar
nature that is beyond the control of the parties.  In the event of such
occurrence, this Agreement shall be amended by mutual agreement to reflect an
extension in the period of performance and/or time of delivery.  Failure to
agree on an equitable extension shall be considered a dispute and resolved in
accordance with Section 18.

         (f)            Waiver.  It is understood and agreed that no failure or
delay by either ORBCOMM or Licensee in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, power or privilege hereunder.  No waiver of any
terms or conditions of this Agreement shall be deemed to be a waiver of any
subsequent breach of any term or condition.  All waivers must be in writing and
signed by the party sought to be bound.

         (g)            Severability.  If any part of this Agreement shall be
held unenforceable, the remainder of this Agreement will nevertheless remain in
full force and effect.

         (i)            Independent Contractors.  Licensee and ORBCOMM are
independent contractors to one another, neither party has the authority to bind
the other in any way or to any third party, and nothing in this Agreement shall
be construed as granting either party the right or authority to act as a
representative, agent, employee or joint venturer of the other.

require Licensee to make a cash deposit or to provide ORBCOMM with an
irrevocable letter of credit in favor of ORBCOMM issued by a bank acceptable to
ORBCOMM.

         (n)            Equitable Relief.  Each of the parties acknowledges
that the ORBCOMM System and the ORBCOMM Services provided pursuant to this
Agreement are unique and recognizes and affirms that in the event of any breach
of this Agreement by it, money damages may not be adequate and the other party
may have no adequate remedy at law.  Accordingly, each of the parties agrees
that the other party shall have the right, in addition to any other rights and
remedies existing in its favor, to enforce its rights and the other party's
obligations hereunder not only by an action or actions for damages but also an

         Permits are not obtained for any of the countries in the Territory,
         ORBCOMM shall have the right to delete such country from the
         definition of the Territory; provided, however, that ORBCOMM shall not
         be entitled to exercise this right until two years from the Effective
         Date. In addition, if any previously granted Permits for a country are
         withdrawn for any reason, ORBCOMM shall have the right to delete that
         country from the definition of the Territory;

         and June 1 of each year a copy of its current marketing communications
         plan covering the next six months that includes a general description
         of the advertising, promotional and marketing efforts for such period;

                 (v)              Operate the Licensee System in a manner so as

         commercial viability of any other system that uses the ORBCOMM System
         and is operated by or on behalf of any of the ORBCOMM Entities or a
         licensee of one of the foregoing;

                 (vi)             (A)  To the extent permitted by applicable
         law, during the term of this Agreement and only so long as such use is
         in accordance with the terms and conditions set forth herein, use the
         ORBCOMM logos and all ORBCOMM trademarks and service marks, which
         Licensee acknowledges are currently owned by OCC or ORBCOMM Global, as
         the case may be, in Licensee's marketing and advertising for the
         Licensee System.  All such marketing and advertising that contains
         references to the ORBCOMM System, ORBCOMM USA, ORBCOMM Global or
         ORBCOMM shall be in accordance with the ORBCOMM Identity Manual, the
         current version of which is attached hereto as Attachment F and which
         may be modified by ORBCOMM after giving Licensee five business days
         prior written notice (the "ORBCOMM Identity Manual"), provided that,
         for a period of six months from the receipt of such notice, Licensee
         shall be entitled to continue to use all existing marketing materials
         that previously complied with the ORBCOMM Identify Manual.  Licensee
         shall be required to obtain the prior written consent of ORBCOMM for
         all such marketing or advertising; provided that if Licensee complies
         with the ORBCOMM Identity Manual, the advance written approval of
         ORBCOMM shall not be required.  Licensee shall obtain all Permits from
         all applicable Governmental Authorities to use ORBCOMM logos,
         trademarks and service marks in the Territory.  To the extent not
         otherwise previously done so and to the extent permitted by law,
         Licensee shall register such logos, trademarks and service marks in
         ORBCOMM Global's name in the Territory.  Prior to registering such
         logos, trademarks and service marks in ORBCOMM Global's name, Licensee
         shall advise ORBCOMM of its intent to do so and of the out-of-pocket
         costs that it expects to incur.  On receipt of ORBCOMM's written
         consent, Licensee shall proceed with such registration and, on
         completion of the process, shall be reimbursed for the actual
         out-of-pocket costs incurred by it up to an amount equal to its
         out-of-pocket cost estimate.  Any use of the word "ORBCOMM" or the
         phrase "ORB" for a logo, trademark, service mark or trade name shall
         also require the prior written approval of ORBCOMM;

                 (B)  Cooperate with ORBCOMM in providing reasonable support
         and any information that may be required in the defense in the
         Territory of the ORBCOMM logo and all ORBCOMM trademarks and service
         marks as a result of their use pursuant to this Agreement; and

                 (C)  During the term of this Agreement and thereafter, not (x)
         engage in any activities or commit any acts that may, directly or
         indirectly, contest, dispute or otherwise impair OCC's or ORBCOMM
         Global's, as the case may be, right, title and interest in such logos,
         trademarks and service marks or (y) directly or indirectly, sublicense
         use of the ORBCOMM logo or any ORBCOMM trademarks and service marks to
         any other person, other than with respect to any Reseller or its
         Agents or Subagents, without the express written consent of ORBCOMM;

                 (vii)            Pay to ORBCOMM the fees, costs and other
         payments set forth in this Agreement;

                 (viii)           Give ORBCOMM and/or its representatives
         reasonable access during normal business hours to Licensee's books,
         accounts, records, contracts and documents concerning the Licensee
         System or otherwise necessary to demonstrate compliance by Licensee
         with the terms and conditions set forth in this Agreement;

                 (ix)             In addition to ORBCOMM's access to the
         ORBCOMM System in the Territory permitted by Section 2(a), permit
         ORBCOMM or any other ORBCOMM Entity and/or their representatives or
         Affiliates, at their expense, to directly and electronically
         communicate with all elements of the Licensee System, other than the
         Subscriber Management and Customer Support Software, for the purpose
         of (A) examining subscriber provisioning parameters, as well as
         network element configuration, use of the ORBCOMM System, performance
         of the Licensee System and other data as required to ensure the proper
         operation of the ORBCOMM System including the Licensee System and (B)
         to the extent ORBCOMM is obligated to do so, assisting Licensee in the
         maintenance and repair of the Licensee System; provided that, in
         either event, ORBCOMM shall use all good faith efforts to minimize its
         interference with the operation of the Licensee System;

                 (x)              If it provides ORBCOMM Services directly to
         Subscribers, include provisions substantially identical to those set
         forth in subsections (f)(i)-(v) of the section entitled "Reseller
         Responsibilities" on Attachment D in its contracts or agreements with
         each of its Subscribers for the Licensee System;

                 (xi)             Use the ORBCOMM Licensed Gateway Software
         only in accordance with the terms and conditions set forth in the
         ORBCOMM Gateway Software License Agreement;

                 (xii)            Not discriminate against any Subscriber
         because such Subscriber purchased or obtained its Subscriber
         Communicator from one source versus another and not offer service to
         Subscribers, who buy or lease their Subscriber Communicators from





                                       8
<PAGE>   9
         Licensee or an Affiliate of Licensee, at a price that is lower than
         that at which similar ORBCOMM Services are offered to Subscribers who
         obtain their Subscriber Communicators from another source;

                 (xiii)           To the extent permitted by law and except as
         permitted in Sections 2(b)(ii) and 7, (A) not register on the Licensee
         System Subscriber Communicators the billing address for which is
         outside the Territory and (B) not solicit any third party, establish
         an office outside the Territory for the purpose of soliciting any
         third party or accept unsolicited offers from any third party that
         will use the Licensee System, if such use will occur primarily in the
         territory of any one other ORBCOMM System service licensee.  During
         the term of this Agreement, Licensee shall provide ORBCOMM with an
         officer's certificate certifying its compliance with the terms of this
         Section 3(a)(xiii);

                 (xiv)            To the extent permitted by law, offer to
         provide service to any reseller that has been accredited as an
         approved ORBCOMM Service reseller by another ORBCOMM service licensee,
         at substantially the same rates, terms and conditions as it offers
         other, similar resellers of the ORBCOMM Services in the same country
         in the Territory, or if there are no similar resellers in such
         country, then at rates, terms and conditions that are commercially
         reasonable; provided, however, that in the event Licensee does not
         desire to provide service to such reseller, Licensee shall provide
         ORBCOMM with its reasons therefor and request that ORBCOMM cause
         ORBCOMM Global to review such reseller for the purpose of either
         approving or disapproving such reseller as an accredited ORBCOMM
         Service reseller.  In the event such reseller is accredited as an
         approved ORBCOMM Service reseller by ORBCOMM Global, Licensee shall be
         required to offer to provide service to such reseller in accordance
         with this Section 3(a)(xiv).  If such reseller is not so accredited by
         ORBCOMM Global, Licensee shall be under no obligation to provide
         service to such reseller in accordance with this Section 3(a)(xiv);

                 (xv)             Offer to provide in the Territory the full
         range of ORBCOMM Services that are described in the ORBCOMM Service
         Features Description, as it may be amended from time to time, the
         current version of which is set forth in Attachment A;

                 (xvi)            Promptly advise ORBCOMM in writing if
         Licensee or any of its Affiliates is a Reseller or acquires any direct
         or indirect ownership or other economic interest in a Reseller and
         provide to ORBCOMM for its approval, which approval shall not be
         unreasonably withheld, all proposed or previously executed Reseller
         Agreements, and any amendments or modifications thereto, with such
         Reseller, together with an explanation and justification of the terms
         and conditions set forth therein;

                 (xvii)           Prior to the commencement of the provision of
         ORBCOMM Services in the Territory and within 15 days after the end of
         each calendar quarter thereafter, provide to ORBCOMM in writing a full
         description of its prices and pricing strategy for the provision of
         ORBCOMM Services in the Territory.  Such description shall (A) address
         the issues of competitive pricing in the Territory, (B) demonstrate
         that the pricing strategy and the prices serve the purpose of
         maximizing revenues consistent





                                          9
<PAGE>   10
         with or greater than the financial returns reflected in the mutually
         agreed to Licensee System Business Plan, a copy of which is attached
         hereto as Attachment G (the "Licensee System Business Plan"), and of
         making efficient and appropriate use of the Satellites, and (C)
         demonstrate that ORBCOMM Services have been appropriately priced, when
         combined with other services or hardware provided by Licensee or its
         Resellers, and accounted for in calculating gross operating revenues
         pursuant to Section 5(a).  Such pricing policies and strategies are
         not subject to the approval of ORBCOMM, and Licensee shall be
         obligated to disclose to ORBCOMM the identity of its Resellers but
         shall not be obligated to disclose to ORBCOMM the identity of its or
         its Reseller's Subscribers;

                 (xviii)          Establish a mutually agreeable framework and
         reporting scheme with ORBCOMM for the joint exchange of operational
         statistics (such as statistical data on message lengths, message
         frequencies, time of day, day of week and seasonal usage for each
         service offering and market segment served by Licensee) that are
         necessary for the Licensee, ORBCOMM and other ORBCOMM System service
         licensees to appropriately manage their respective systems and provide
         consistent quality services using the ORBCOMM System;

                 (xix)            Participate with ORBCOMM in the preparation
         of traffic forecasts;

                 (xx)             Send ORBCOMM written notice of when the
         Licensee System commences operation;

                 (xxi)            Pay all country, federal, state, local and
         other taxes, including but not limited to sales, use, gross receipts,
         and excise taxes and withholding, that arise from the performance of
         its duties under this Agreement, including the payment of all fees and
         other amounts due and owing hereunder;

                 (xxii)           From three months after the System Available
         Date, make available to ORBCOMM operations personnel responsible for
         the Licensee System, who collectively shall be available 24 hours a
         day, seven days a week;

                 (xxiii)          Operate the ORBCOMM Gateway located in the
         Territory using software, firmware and hardware in accordance with the
         currently-approved ORBCOMM Global specified configuration therefor,
         which may change from time to time; and

                 (xxiv)           Prior to or concurrently with the execution
         of this Agreement, execute the Ground Segment Procurement Contract,
         the ORBCOMM Gateway Software License Agreement and the CSC Software
         License Agreement.

         (b)     Responsibilities of ORBCOMM.  ORBCOMM shall:

                 (i)              Cooperatively work with and encourage the
         manufacturers and suppliers of Subscriber Communicators to offer such
         Subscriber Communicators within one year





                                       10
<PAGE>   11
         of the Effective Date for sale or lease in the Territory, either
         directly or through distributors, one of which may be Licensee;

                 (ii)             Provide no later than  60 days prior to the
         Licensee System Acceptance Test (as set forth in the Gateway
         Implementation Plan), the Licensee System Acceptance Specifications
         and written acceptance test procedures for performing the Licensee
         System Acceptance Test.  The Licensee System Acceptance Specifications
         shall be sufficient to ensure that all the features and functions of
         the Licensee System are operating properly and in a manner compatible
         with the ORBCOMM System;

                 (iii)            Assist Licensee in providing data relating to
         the ORBCOMM System required by any Governmental Authority in
         connection with Licensee obtaining any of the Permits if ORBCOMM
         determines that Licensee cannot reasonably provide such data itself;
         provided that written data that exists or that ORBCOMM can readily
         compile from existing data shall be provided at ORBCOMM's expense and
         other written data or any data required to be presented in person or
         orally shall be provided at Licensee's expense; and provided further
         that ORBCOMM shall not be required to disclose any such data to the
         extent prohibited by law and without reasonable assurances that such
         data will be maintained by the receiving party on a confidential
         basis;

                 (iv)             Use commercially reasonable efforts to
         provide, free of charge except as provided below, 24-hour a day, seven
         days a week emergency technical advice concerning the operation,
         maintenance and repair of the Licensee System.  Requests for emergency
         technical advice may be made by telephone or facsimile and the advice
         may be provided by ORBCOMM using such similar means, with all
         communications conducted in the English language; provided that if, in
         ORBCOMM's business discretion, the nature of these requests or their
         frequency indicate that Licensee's operators or technicians are
         technically inadequate for their tasks, ORBCOMM may require that these
         employees be retrained (or, at Licensee's option, replaced) at
         Licensee's cost, or ORBCOMM may charge for this advice in accordance
         with Section 8(b) of the Ground Segment Procurement Contract; and
         provided further that, until three months after the System Available
         Date, emergency technical advice shall only be available between the
         hours of 9:00 a.m. and 5:00 p.m. United States Eastern Standard Time
         (or United States Eastern Daylight Time as applicable) on regular
         business days;

                 (v)              Implement its own advertising and other
         promotional programs for the ORBCOMM System, the scope and timing of
         which shall be in ORBCOMM's sole discretion;

                 (vi)             Use all good faith effort to cause ORBCOMM
         USA and all other ORBCOMM service licensees to offer to any of
         Licensee's Resellers rights substantially similar to those set forth
         in Section 3(a)(xiv);

                 (vii)            Establish a mutually agreeable framework and
         reporting scheme with Licensee for the joint exchange of operational
         statistics (such as statistical data on





                                       11
<PAGE>   12
         message lengths, message frequencies, time of day, day of week and
         seasonal usage for each service offering and market segment served by
         Licensee) that are necessary for the Licensee, ORBCOMM and other
         ORBCOMM System service licensees to appropriately manage their
         respective systems and provide consistent quality services using the
         ORBCOMM System;

                 (viii)           To the fullest extent permitted by applicable
         law, rule or regulation of any Governmental Authority, include
         language substantially similar to Section 3(a)(xiii) in each service
         license agreement it executes after the date hereof; and

                 (ix)             Prior to or concurrently with the execution
         of this Agreement, execute the Ground Segment Procurement Contract and
         the ORBCOMM Gateway Software License Agreement.


SECTION 4 - LICENSE FEE

         (a)     In addition to any other fees or payments specified herein,
Licensee shall pay to ORBCOMM the sum of [CONFIDENTIAL TREATMENT] (the "License
Fee") ") as consideration for the grant of the License.  The License Fee shall
be payable on the Effective Date to a bank account of ORBCOMM specified in
writing.

         (b)            (i)  [CONFIDENTIAL TREATMENT], in recognition of the
early date at which Licensee became a Candidate Licensee for the Territory,
[CONFIDENTIAL TREATMENT] shall be [CONFIDENTIAL TREATMENT] of the Licensee
System as specified in Section [CONFIDENTIAL TREATMENT].  Upon the occurrence
of such a [CONFIDENTIAL TREATMENT], the [CONFIDENTIAL TREATMENT], as
[CONFIDENTIAL TREATMENT] as provided below, shall become [CONFIDENTIAL
TREATMENT] within [CONFIDENTIAL TREATMENT] business days of such [CONFIDENTIAL
TREATMENT]; provided, however, that if such a [CONFIDENTIAL TREATMENT] shall
not have occurred by the [CONFIDENTIAL TREATMENT], the payment of the
[CONFIDENTIAL TREATMENT] shall be [CONFIDENTIAL TREATMENT].

         (ii)           For purposes of this Agreement, a change of control
with respect to Licensee shall be deemed to have occurred if the Controlling
Shareholders in the aggregate shall (a) cease to own, directly or indirectly,
at least [CONFIDENTIAL TREATMENT] percent of the issued and outstanding shares
of capital stock or other interests of Licensee entitled to vote generally for
the election of directors or persons performing similar functions or (b) not
have the ability to elect a [CONFIDENTIAL TREATMENT] of the directors or
persons performing similar functions of Licensee.

         (iii)          The [CONFIDENTIAL TREATMENT] shall be [CONFIDENTIAL
TREATMENT] by an amount equal to [CONFIDENTIAL TREATMENT] percent per annum for
each year or portion thereof from the Effective Date until the [CONFIDENTIAL
TREATMENT].

SECTION 5 - SATELLITE USAGE FEES

         In addition to any other fees or payments specified herein, Licensee
shall pay to ORBCOMM a fee for the use of the Satellites (the "Satellite Usage
Fee") in accordance with the following terms and conditions:

                        (a)       Amount of Fee.  (i)  The Satellite Usage Fee
         for a calendar month shall be equal to the greater of (A)
         [CONFIDENTIAL TREATMENT] percent (the "Revenue Dependent Fee
         Percentage") of Licensee's gross operating revenues for such month
         (the "Revenue Dependent Amount") and (B) [CONFIDENTIAL TREATMENT] (the
         "Data Throughput Fee Amount") multiplied by the number of KBytes of
         data originating from or terminating to Subscriber Communicators
         registered on or provided roaming services by the Licensee System at
         any time during such month and processed by Licensee's ORBCOMM Gateway
         (excluding bytes added to the Subscriber's message by the ORBCOMM
         System).

                        (ii)      For purposes of this Agreement, in
         calculating the Revenue Dependent Amount gross operating revenues
         shall:

                                  (A)      be calculated using the amounts
                        invoiced or that could have been invoiced during a
                        calendar month by Licensee, whether these amounts are
                        collected or not;

                                  (B)      include all revenue derived,
                        directly or indirectly, from [CONFIDENTIAL TREATMENT]
                        and other fees for ORBCOMM Services, including all
                        revenue derived as a provider of roaming or
                        multinational account services;

                                  (C)      if such a long message surcharge has
                        not been charged Resellers and Subscribers, in the
                        event Licensee provides services directly to
                        Subscribers, be calculated to include a long message
                        surcharge, equal to at least [CONFIDENTIAL TREATMENT]
                        (or its equivalent in the applicable currency) for each
                        message whose length is between [CONFIDENTIAL
                        TREATMENT] and [CONFIDENTIAL TREATMENT] bytes,
                        inclusive, or equal to at least [CONFIDENTIAL
                        TREATMENT] (or its equivalent in the applicable
                        currency) for each message whose length exceeds
                        [CONFIDENTIAL TREATMENT] bytes;

                                  (D)   be calculated assuming that ORBCOMM
                        Services combined with other services or hardware
                        provided by Licensee or its Resellers were priced no
                        less than similar ORBCOMM Services provided on a stand
                        alone basis;

                                  (E)      exclude those revenues derived from
                        another third party derived as a provider of roaming or
                        multinational account services and any surcharge due
                        and owing to ORBCOMM in connection with roaming or
                        multinational account services; and





                                       13
<PAGE>   14
                                       (F)         exclude all value-added or
                        similar taxes or assessments that Licensee is required
                        by applicable law to collect from its customers and
                        remit to Governmental Authorities in the Territory.

                        (iii)          In calculating the Revenue Dependent
         Amount or the Data Throughput Fee Amount any data throughput
         associated with a Subscriber Communicator registered or used by any of
         ORBCOMM Global, ORBCOMM USA, or ORBCOMM for purposes of maintenance
         and testing shall be excluded.

                        (iv)           ORBCOMM may, in its discretion, change
         the Revenue Dependent Fee Percentage and/or the Data Throughput Fee
         Amount; provided that ORBCOMM shall not be entitled to make any such
         change (A) before [CONFIDENTIAL TREATMENT], (B) more than
         [CONFIDENTIAL TREATMENT] time in any [CONFIDENTIAL TREATMENT] month
         period, provided that a change in [CONFIDENTIAL TREATMENT] or the
         [CONFIDENTIAL TREATMENT] shall for purposes of this Section be
         [CONFIDENTIAL TREATMENT], (C) without giving Licensee [CONFIDENTIAL
         TREATMENT] days advance written notice thereof. In addition:

                                       (x)         with respect to the Revenue
                        Dependent Fee Percentage, ORBCOMM shall not be entitled
                        to make any change thereto in an increment of more than
                        [CONFIDENTIAL TREATMENT] percent at any one time and
                        the Revenue Dependent Fee Percentage shall not be more
                        than [CONFIDENTIAL TREATMENT] percent; and

                                       (y)         with respect to the Data
                        Throughput Fee Amount, ORBCOMM shall not be entitled to
                        make any change thereto in an increment of more than
                        [CONFIDENTIAL TREATMENT] percent of the then existing
                        rate at any one time and the Data Throughput Fee Amount
                        shall not be more than [CONFIDENTIAL TREATMENT] per
                        KByte.

                        (b)            Payment of Fee.  (i)  Within
         [CONFIDENTIAL TREATMENT] days of the end of each calendar month,
         Licensee shall advise ORBCOMM in writing of Licensee's calculation of
         the total gross operating revenues for such calendar month, in the
         currencies in which Licensee invoices its customers, and the number of
         KBytes of data originating from or terminating to Subscriber
         Communicators registered on or provided roaming service by the
         Licensee System at any time during such month and processed by the
         Licensee's ORBCOMM Gateway (excluding bytes added to the Subscriber's
         message by the ORBCOMM System).  Within [CONFIDENTIAL TREATMENT]
         calendar days of the end of each calendar month, ORBCOMM shall compute
         and invoice Licensee for the actual Satellite Usage Fee payment for
         such month, in U.S. dollars, using the official exchange rate in
         effect at Morgan Guaranty Trust Company of New York at the close of
         business in New York on the last business day of such calendar month.
         In the event that Licensee does not provide ORBCOMM with any of the
         foregoing information, ORBCOMM may make its own estimate thereof,
         which estimate shall be conclusive and binding on Licensee, and
         compute the amount to be invoiced using such estimate.





                                       14

                        (ii)           Within [CONFIDENTIAL TREATMENT] days of
         the receipt of the Satellite Usage Fee invoice, Licensee shall pay the
         Satellite Usage Fee by electronic fund transfer to the bank account
         specified by ORBCOMM.  All Satellite Usage Fees remaining unpaid after
         such [CONFIDENTIAL TREATMENT] day period shall bear interest until
         paid at the rate equal to [CONFIDENTIAL TREATMENT] times the prime
         rate or rates announced by Morgan Guaranty Trust Company of New York
         during the period of nonpayment.

                        (iii)          If payments due under this Section 5
         cannot be made as provided herein due to [CONFIDENTIAL TREATMENT] or
         other [CONFIDENTIAL TREATMENT] in each and every country or territory
         within the Territory, subject to Section [CONFIDENTIAL TREATMENT],
         ORBCOMM shall permit Licensee to [CONFIDENTIAL TREATMENT].


SECTION 6 - SUBSCRIBER MANAGEMENT AND CUSTOMER SUPPORT SYSTEM

         To the fullest extent permitted by law, the parties to this Agreement
acknowledge and agree that it is critical that (a) in the universal
commissioning of new applications using the ORBCOMM System, Licensee and other
ORBCOMM System service licensees have a billing and customer support system
that can adequately and appropriately bill and manage Resellers and Subscribers
for such applications, as well as provide associated customer support
functions, and (b) Multinational Accounts be established.  It is essential,
therefore, that Licensee obtain a license from CSC Intelicom, Inc. ("CSC") for
the subscriber management and customer support system software (the "Subscriber
Management and Customer Support Software") Licensee will use for ORBCOMM
Services using the Licensee System.  Licensee hereby agrees to obtain a license
for the Subscriber Management and Customer Support Software and purchase
certain hardware from CSC on the terms and conditions specified in the Software
License Agreement attached hereto as Attachment H (the "CSC Software License
Agreement").


SECTION 7 - ROAMING ARRANGEMENTS AND MULTINATIONAL ACCOUNTS

         ORBCOMM shall establish an International Marketing Council, which
Council shall include all ORBCOMM System service licensees.  The International
Marketing Council shall consider, among other things, the terms and conditions
on which roaming arrangements and multinational accounts shall be established
for ORBCOMM System service licensees. Licensee and ORBCOMM agree to be bound by
the determinations of the International Marketing Council with respect to
roaming arrangements and multinational accounts.


SECTION 8 - PROPER OPERATION OF THE LICENSEE SYSTEM

         (a)            Performance of Tests.  (i)  Once a calendar year,
Licensee shall permit ORBCOMM and/or its representatives access to the Licensee
System, other than the Subscriber Management and Customer Support Software, for
the purpose of performing a quality inspection (the "Quality Inspection"),
which shall be conducted to determine compliance with





                                       15
<PAGE>   16
the provisions of this Agreement.  The Quality Inspection (A) may be conducted
only after ORBCOMM has given the Licensee seven days prior written notice
thereof, (B) shall be conducted in a way that minimizes the interference with
Licensee's normal business operations, and (C) may include a Licensee System
Acceptance Test that requires some assistance from Licensee's personnel.  All
costs of Quality Inspections, other than the costs, including any out-of-pocket
expenses, associated with the assistance received by ORBCOMM from Licensee's
personnel specified in clause (C) above, shall be borne by ORBCOMM; provided,
however that if the Quality Inspection demonstrates that the Licensee System is
not operating in accordance with the Licensee System Acceptance Specifications,
Licensee shall bear the cost of such Quality Inspection.

         (ii)           In addition to the foregoing, if, subsequent to the
initial Licensee System Acceptance Test, in ORBCOMM's reasonable opinion, there
are grounds to believe that the Licensee System is not operating in accordance
with the Licensee System Acceptance Specifications, ORBCOMM shall be entitled,
at its option, (A) to require Licensee to perform a Licensee System Acceptance
Test or (B) to perform a Licensee System Acceptance Test itself.  If ORBCOMM
elects to require Licensee to take the action specified in (A) above, ORBCOMM
shall advise Licensee in writing of such election and Licensee must perform, or
have performed, the test within ten days thereafter.  If ORBCOMM elects to
perform the Licensee System Acceptance Test itself, ORBCOMM shall advise
Licensee in writing of such election and Licensee shall provide ORBCOMM and its
representatives access to Licensee's facilities, including its equipment.  The
cost to perform the Licensee System Acceptance Test shall be borne solely by
Licensee and, if performed by ORBCOMM, shall be at the rate for On-Site
Technical Assistance Services set forth in Section 8(a) of the Ground Segment
Procurement Contract; provided that, if after completion of such test, ORBCOMM
reasonably concludes that (x) the reason the Licensee System was not operating
in accordance with the Licensee System Acceptance Specifications was the result
of a defect in the ORBCOMM Gateway covered by the warranty provisions set forth
in Section 6 of the Ground Segment Procurement Contract or (y) the Licensee
System is operating in accordance with the Licensee System Acceptance
Specifications, the cost of the Licensee System Acceptance Test including
Licensee's out-of-pocket costs in connection therewith, shall be borne by
ORBCOMM.

         (b)            Corrective Action.  If ORBCOMM determines from the
Licensee System Acceptance Test that the Licensee System is not operating in
accordance with the Licensee System Acceptance Specifications, or if the
Licensee System is operating in violation of any applicable law, rule or
regulation of any Governmental Authority and such law, rule or regulation
requires immediate cessation of operation, ORBCOMM shall be entitled to require
Licensee immediately to cease operation of the Licensee System and, if Licensee
fails to cease operation of the Licensee System, ORBCOMM shall be entitled to
terminate Licensee's access to the ORBCOMM System until ORBCOMM determines that
all necessary corrections have been made by Licensee; provided however, that,
if only a portion of the Licensee System is not operating in accordance with
the Licensee System Acceptance Specifications, or only a portion of the
Licensee System is operating in violation of any such law, rule or regulation,
and ORBCOMM determines that cessation of the non-conforming portion only of the
Licensee System will not injure the ORBCOMM System, is technically consistent
with the ORBCOMM System architecture and is operationally feasible, ORBCOMM
shall notify Licensee of such





                                       16
<PAGE>   17
determination and Licensee shall be entitled to cease operating the
non-conforming portion only of the Licensee System.  Notwithstanding the
foregoing proviso, in the event the corrections required by this Section 8 are
not made within three months of receipt by Licensee of written notice thereof,
ORBCOMM shall be entitled to terminate this Agreement.


SECTION 9 - TERM OF AGREEMENT

         (a)            Term.  Subject to the provisions set forth in this
Section 9, this Agreement shall have a term of ten years, commencing on the
Effective Date.  Within one year prior to the expiration of the initial term of
this Agreement, Licensee may request that this Agreement be extended for a
further period of up to ten years, which request shall not be unreasonably
denied by ORBCOMM.  To the extent such extension is granted, ORBCOMM shall not
charge Licensee a service license fee for such extension.

         (b)            Termination.

         (i)            Termination by Licensee.  Subject to the provisions of
Section 12, this Agreement may be terminated by Licensee one year after
providing to ORBCOMM written notice of termination.  In addition, this
Agreement may be terminated by Licensee at any time after the occurrence of any
of the following events of default:

                        (A)            Any representation or warranty made by
         ORBCOMM in this Agreement or any other document delivered pursuant to
         this Agreement including the Ground Segment Procurement Contract and
         the ORBCOMM Gateway Software License Agreement shall be false or
         misleading in any material respect;

                        (B)            ORBCOMM shall fail to observe or perform
         any of its obligations under this Agreement, and such failure shall
         remain uncured for a period of [CONFIDENTIAL TREATMENT] days after
         receipt by ORBCOMM of written notice thereof;

                        (C)            ORBCOMM shall become insolvent, admit in
         writing its inability to pay its debts as they become due, make a
         general assignment for the benefit of creditors, suffer or permit the
         appointment of a receiver for its business or assets, initiate or
         become subject to any proceeding under any bankruptcy or insolvency
         law, whether domestic or foreign, or liquidate or wind up, voluntarily
         or otherwise;

                        (D)            Licensee shall have exercised its rights
         set forth in Section 13(a); or

                        (E)            An event of default by ORBCOMM shall
         have occurred under Section 9(a) of the Ground Segment Procurement
         Agreement or under Section 7(a) of the ORBCOMM Gateway Software
         License Agreement.

         (ii)           Termination by ORBCOMM.  This Agreement may be
terminated by ORBCOMM at any time after the occurrence of any of the following
events of default:

<PAGE>   18
                        (A)            Licensee shall fail to pay any amount
         due under this Agreement, including the Satellite Usage Fee, within
         [CONFIDENTIAL TREATMENT] days after receipt of notice from ORBCOMM
         that such amount is due;

                        (B)            Any representation or warranty made by
         Licensee in this Agreement or any other document delivered pursuant to
         this Agreement including the Ground Segment Procurement Contract and
         the ORBCOMM Gateway Software License Agreement shall be false or
         misleading in any material respect;

                        (C)            Licensee shall fail to observe or
         perform any of its obligations under Section 8(b);

                        (D)            Licensee shall fail to observe or
         perform any of its obligations under this Agreement (other than
         breaches specified in Sections 9(b)(ii)(A), (C), (H), (I) or (J)), and
         such failure shall remain uncured for a period of [CONFIDENTIAL
         TREATMENT] days after receipt by Licensee of written notice thereof;

                        (E)            Licensee shall become insolvent, admit
         in writing its inability to pay its debts as they become due, make a
         general assignment for the benefit of creditors, suffer or permit the
         appointment of a receiver for its business or assets, initiate or
         become subject to any proceeding under any bankruptcy or insolvency
         law, whether domestic or foreign, or liquidate or wind up, voluntarily
         or otherwise;

                        (F)            Currency exchange restrictions that
         prevent Licensee from making its payments to ORBCOMM in U.S. dollars
         shall be imposed by any Governmental Authority and continue in effect
         for more than two years;

                        (G)            Any law shall be enacted or exist in any
         part of the Territory that imposes any tax or other assessment,
         including withholding taxes, on the License Fee, Satellite Usage Fee
         or any amounts owed by Licensee under any of the other Transaction
         Agreements that is not borne solely by Licensee;

                        (H)            (x)  Licensee's actual gross operating
         revenues for the provision of ORBCOMM Services in the Territory for
         the [CONFIDENTIAL TREATMENT] year period commencing on the date there
         are [CONFIDENTIAL TREATMENT] or more [CONFIDENTIAL TREATMENT] is less
         than [CONFIDENTIAL TREATMENT] of the gross operating revenues
         reflected in the Licensee System Business Plan for the first
         [CONFIDENTIAL TREATMENT] years after the assumed date in the Licensee
         System Business Plan when there would have been [CONFIDENTIAL
         TREATMENT] or more [CONFIDENTIAL TREATMENT], or (y) total Satellite
         Usage Fees in the first full calendar year after the expiration of
         such [CONFIDENTIAL TREATMENT] year period, shall be less than 
         [CONFIDENTIAL TREATMENT] percent of the total Satellite Usage Fees for
         the previous calendar year; provided that for purposes of this Section
         12(b)(ii)(H) only, in calculating the amounts of the Satellite Usage
         Fees a constant set of currency exchange rates shall be used; and
         provided further that this percentage shall be [CONFIDENTIAL
         TREATMENT], if the number of [CONFIDENTIAL TREATMENT] on [CONFIDENTIAL
         TREATMENT] of the [CONFIDENTIAL TREATMENT] year is less





                                       18
<PAGE>   19
         than the number of [CONFIDENTIAL TREATMENT] on [CONFIDENTIAL
         TREATMENT] of the previous year, in accordance with the following
         formula: [CONFIDENTIAL TREATMENT] (number of [CONFIDENTIAL TREATMENT]
         on [CONFIDENTIAL TREATMENT] of the [CONFIDENTIAL TREATMENT]

         thereafter fail to maintain, the Permits required to operate the
         Licensee System in at least one of the countries comprising the
         Territory; or

                        (K)            An event of default by Licensee shall
         have occurred under Section 9(b) of the Ground Segment Procurement
         Agreement, Section 7(b) of the ORBCOMM Gateway Software License
         Agreement, or under the CSC Software License Agreement.

         (c)            Remedies on Termination.  (i)  Upon termination of this
Agreement by Licensee for convenience pursuant to Section 9(b)(i) or by ORBCOMM
pursuant to Section 9(b)(ii), to the fullest extent permitted by law, ORBCOMM
shall be entitled, in its discretion, to become a sublicensee of Licensee and
operate and manage the Licensee System to ensure that there is as little
interruption as possible in the provision of ORBCOMM Services in the Territory.
Licensee agrees to cooperate in a commercially reasonable manner and actively
participate, including with respect to the transfer of the Permits in the
Territory and providing ORBCOMM information on its Resellers, in ensuring
continued operations until such time that a new entity has been granted the
necessary Permits for the Territory and is ready to start operations.

         (ii)           Subject to Section 14, termination of this Agreement by
the party not in default in accordance with the terms hereof shall be without
prejudice to any other rights or remedies such party shall have by law.

         (d)            Abandonment of ORBCOMM System.  Nothing contained in
this Agreement shall prevent the ORBCOMM Entities from ceasing to develop,
construct or operate the ORBCOMM System.  In the event ORBCOMM or any of the
ORBCOMM Entities abandon the ORBCOMM System by ceasing to develop, construct
and operate all of the ORBCOMM System, ORBCOMM shall be entitled to terminate
this Agreement by giving Licensee 180 days written notice.  In such event, to
the fullest extent permitted by applicable law, Licensee shall have the right,
together with all other persons who may have a similar right and a desire to
exercise such right, all of whom shall be obligated to act as a group (the
"ORBCOMM System Purchase Group"), to purchase the tangible assets of the
ORBCOMM System owned by ORBCOMM Global, ORBCOMM USA, or ORBCOMM and to purchase
a non-exclusive, perpetual license to use, solely in connection with the
operation of the tangible assets purchased pursuant to this Section 9(d), the
intangible assets of the ORBCOMM System, other than any operating or regulatory
licenses with respect to the ORBCOMM System, owned by ORBCOMM Global, ORBCOMM
USA, or ORBCOMM at their then fair market value, which right shall be exercised
by the ORBCOMM System Purchase Group within three months of





                                       19
<PAGE>   20
receipt of written notice from ORBCOMM of abandonment (the "Option Exercise
Notice"). The fair market value of the tangible assets and such license for the
intangible assets of the ORBCOMM System shall be determined as of the day of
abandonment and on the basis of an arms' length transaction between a willing
buyer and a willing seller.  Any determination of fair market value pursuant to
this Section 9(d) shall be final, binding and conclusive on the parties.  Fair
market value shall be determined as follows:

                        (i)            Promptly after delivery of the Option
         Exercise Notice, ORBCOMM and the ORBCOMM System Purchase Group shall
         attempt in good faith to agree on the fair market value.  If ORBCOMM
         and the ORBCOMM System Purchase Group agree on a value (regardless of
         when such agreement is reached, and notwithstanding the pendency of
         appraisal efforts pursuant to this Section), such value shall be the
         fair market value;

                        (ii)           If ORBCOMM and the ORBCOMM System
         Purchase Group fail to reach such an agreement within one month after
         the delivery of the Option Exercise Notice, they shall each select an
         independent appraiser who is one of the "Big Six" United States
         accounting firms.  If either ORBCOMM or the ORBCOMM System Purchase
         Group shall fail to select an appraiser within twenty (20) days after
         the expiration of the one-month period referred to in the preceding
         sentence, the fair market value shall be determined by the appraiser
         selected by the other.  Following such selection, each such appraiser
         shall determine the value of the tangible and intangible assets of the
         ORBCOMM System to be purchased pursuant to this Section 9(d) as
         quickly as practicable, and in any event within forty-five (45) days
         after the last appraiser has been selected, and give notice of such
         determination to ORBCOMM and the ORBCOMM System Purchase Group.  If
         either appraiser shall fail to make such a determination of value
         within forty-five days after the last appraiser has been selected, the
         fair market value shall be the value determined by the other
         appraiser.  If the greater of the two values determined by such two
         appraisers is within 10% of the lesser of such two values, the fair
         market value shall be the average of such two values.

                        (iii)          If the greater of the two values
         determined by such two appraisers is not within 10% of the lesser of
         such two values, such two appraisers shall select a third independent
         appraiser who shall be one of the "Big Six" United States accounting
         firms and who shall as quickly as practicable, but in no event later
         than forty-five days after appointment, select one of the values
         determined by the first two appraisers as the value that more closely
         approximates the correct fair market value, and such value selected by
         the third appraiser shall be fair market value.

                        (iv)           ORBCOMM and the ORBCOMM System Purchase
         Group agree to cooperate with one another and with the appraisers in
         determining fair market value. ORBCOMM and the ORBCOMM System Purchase
         Group shall each bear its own out-of-pocket expenses incurred in
         connection with the determination of fair market value, including
         without limitation the fees and expenses of the appraiser selected by
         each, and one-half of the fees and expenses of the third appraiser, if
         any.

         sale of the assets specified herein shall occur within 45 days of the
         determination of the fair market value therefor.

         In the event ORBCOMM ceases to develop, construct or operate the

         all commercially reasonable efforts to cooperate with the ORBCOMM
         System Purchase Group in the transfer of  the ORBCOMM System; provided
         that ORBCOMM shall be reimbursed by the ORBCOMM System Purchase Group
         for all of its expenses incurred in providing such cooperation.  In
         addition, ORBCOMM shall continue to operate the ORBCOMM System until
         the expiration of any rights to purchase by the ORBCOMM System

         rights, until consummation of the purchase and sale of the assets as

SECTION 13 - SYSTEM OUTAGES AND FAILURE

         (a)            In the event ORBCOMM is unable to provide Licensee with
access to the ORBCOMM System due to temporary or intermittent problems (not
including planned periods of satellite unavailability) with the ORBCOMM System
other than those temporary or intermittent problems caused by Licensee, any of
its Subscribers or the Licensee System (an "Intermittent Service Problem") for

exclusive remedy shall be to extend the term of this Agreement [CONFIDENTIAL
TREATMENT] day for each day, in excess of such ten days where no service was

DISCLAIMS, AND





                                       23
<PAGE>   24
LICENSEE HEREBY EXPRESSLY WAIVES, RELEASES AND RENOUNCES ALL OTHER WARRANTIES,
OBLIGATIONS AND LIABILITIES OF EACH OF THE ORBCOMM ENTITIES, EXPRESS OR
IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO, INCLUDING, BUT NOT
LIMITED TO, (i) ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE; (ii) ANY IMPLIED WARRANTY ARISING FROM COURSE OF

SUITABILITY FOR USE, THAT IS NOT CONTAINED IN THIS AGREEMENT SHALL BE DEEMED TO
BE A WARRANTY BY ANY OF THE ORBCOMM ENTITIES.

         (b)            Limitation of Liability.  (i)  Each of the parties
acknowledges and understands that the ORBCOMM System is a new, untested system
that entails a high degree of risk of (A) delay in or cancellation of
deployment and (B) launch vehicle, satellite and other equipment or software
failure or impaired performance, and that there can be no assurance that the
ORBCOMM System will be an economically viable system even if successfully
deployed. Each party shall bear all responsibility, risk and cost associated
with developing and maintaining its respective business, and none of the
ORBCOMM Entities shall be liable to Licensee for costs or damages caused by any
schedule delays or failure of the ORBCOMM System or any component thereof,
except as specifically provided in Section 13.

         (ii)           Licensee acknowledges that ORBCOMM shall supply the
service that is the subject of this Agreement on a good faith efforts basis and
that service failures and interruptions may occur and are difficult to assess
as to cause or resulting damages.  In such event and except as otherwise
provided in Section 13, the parties agree that the ORBCOMM Entities shall not
be liable to Licensee for any losses or damages arising out of any failure of
performance, error, omission, interruption, deletion, defect, delay in
operation or transmission, communications line failure, theft or destruction or
unauthorized access to, alteration of or use of records, associated with the
ORBCOMM System or ORBCOMM Services whether for breach of contract, tortious
behavior, negligence, or under any other cause of action.

         (iii)          NOTWITHSTANDING ANYTHING CONTAINED HEREIN TO THE
CONTRARY, IN NO EVENT SHALL EITHER PARTY HAVE ANY OBLIGATION, LIABILITY, RIGHT,
CLAIM OR REMEDY TO THE OTHER UNDER THIS AGREEMENT FOR LOSS OF USE, REVENUE OR
PROFIT OR FOR ANY OTHER INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

<PAGE>   25
         (iv)           In addition, in no event shall ORBCOMM or any of the
other ORBCOMM Entities have any liability under or resulting from this
Agreement and any other Transaction Agreement:

                        (A) until the cumulative aggregate amount of any
         claims, losses costs, expenses, damages or liabilities incurred by
         Licensee for which ORBCOMM would be responsible to Licensee under or
         as a result of this Agreement or any other Transaction Agreement
         exceeds [CONFIDENTIAL TREATMENT] and then only to the extent of such
         excess; and

         (B) in the aggregate in excess of [CONFIDENTIAL TREATMENT].


SECTION 15 - DISPUTE RESOLUTION

         (a)            Subject to the provisions of Section 17(n), in the
event of a claim or controversy regarding any matter covered by this Agreement,
ORBCOMM and Licensee shall use all reasonable efforts to resolve such claim or
controversy within 60 calendar days of receipt by either party of notice of the
existence of any such claim or controversy.  In the event the parties are
unable to agree on the resolution of such claim or controversy within such
period of time, either party may remove the claim or controversy for settlement
by final and binding arbitration in New York, NY, in accordance with the then
existing United States domestic rules of the American Arbitration Association
("AAA") (to the extent not modified by this Section). In the event that more
than one claim or controversy arises under this Agreement, such disputes may be
consolidated in a single arbitral proceeding.  The arbitral tribunal shall be
composed of three arbitrators.  Each of ORBCOMM and Licensee shall appoint one
arbitrator. If any party shall fail to appoint an arbitrator within 30 days
from the date on which the other party's request for arbitration has been
communicated to the first party, such appointment shall be made by the AAA.
The two arbitrators so appointed shall agree upon the third arbitrator who
shall act as chairman of the arbitral tribunal and who have significant
operational expertise in geographically distributed data communications
networks.  If the two appointed arbitrators fail to nominate a chairman within
ten days from the date as of which both arbitrators shall have been appointed,
such chairman shall be selected by the AAA.  In all cases, the arbitrators
shall be fluent in English.  Judgment upon any award rendered by the
arbitrators may be entered in any court having jurisdiction or application may
be made for judicial acceptance of the award and an order of enforcement, as
the case may be.  The parties agree that if it becomes necessary for any party
to enforce an arbitral award by a legal action or additional arbitration or
judicial methods, the party against whom enforcement is sought shall pay all
reasonable costs and attorney's fees incurred by the party seeking to enforce
the award.

         (b)            Pending a final determination by the arbitrators, if
the claim or controversy concerns the payment by Licensee of any fees or
amounts due hereunder (including the right to conduct an audit of such fees or
amounts), ORBCOMM shall have the right to terminate Licensee's access to the
ORBCOMM System and, in the event ORBCOMM elects to exercise such right and
notwithstanding any determination by the arbitrators, Licensee's sole remedy
for such termination by ORBCOMM shall be an extension of the term of this
Agreement equal to the period during which Licensee was denied access to the
ORBCOMM System.





                                       25
<PAGE>   26
         (c)            Except with respect to the application of Section 17(n)
hereof, the rights of the parties under this Section 15 shall be the exclusive
remedy with respect to any claim or controversy regarding any matter covered by
this Agreement.


SECTION 16 - COMPLIANCE WITH LAWS

         Each of the parties shall comply in all material respects with all
applicable laws, rules and regulations of any Governmental Authority in the
performance of its obligations hereunder. In particular, Licensee agrees to
comply with all applicable laws of the United States regarding export controls,
international traffic in arms regulations and foreign corrupt practices.  In
addition, but not in limitation of the foregoing, summaries of the current
provisions of the United States Federal International Traffic in Arms
Regulations and of the Prohibited Foreign Trade Practices Act are set forth in
Attachment J.

or to such other persons or addresses as either party may designate by written
notice to the other. All such notices sent to either Licensee or ORBCOMM shall
be effective the earlier of (i) ten business days after the date of mailing by
sender, or (ii) the date of actual receipt.

         (b)              Successors and Assigns.  This Agreement shall be
binding upon the parties, their successors and permitted assigns.  Subject to
Section 10, neither this Agreement nor any interests or duties of Licensee
hereunder may be assigned in whole or in part (by operation of law or
otherwise) by Licensee without the express written consent of ORBCOMM, which
consent shall not be unreasonably withheld.

         (c)              Entire Agreement.  This Agreement and all attachments
(which are hereby made part of this Agreement) contain the entire understanding
between Licensee and ORBCOMM and supersede all prior written and oral
understandings relating to the subject hereof.  No representations, agreements,
modifications or understandings not contained herein shall be valid or
effective unless agreed to in writing and signed by both parties.  Any
modification or amendment of this Agreement must be in writing and signed by
both parties.

         (d)              Governing Law and Jurisdiction.  (i)  The
construction, interpretation and performance of this Agreement, as well as the
legal relations of the parties arising hereunder, shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to the conflict or choice of law provisions thereof.  The United Nations
Convention on Contracts for the International Sale of Goods (1980) shall not
apply to any provisions of this Agreement.  Neither party may bring any action
for a claim under this Agreement later than one year after the termination of
this Agreement; provided that claims under any provision of this Agreement that
survives termination of this Agreement may be brought within one year of the
later of the occurrence of the event giving rise to the claim and actual
knowledge thereof by the party asserting such claim.

         (ii)  For purposes of Section 17(n), Licensee by its execution hereof
(A) hereby irrevocably submits to the nonexclusive jurisdiction of the state
courts of the State of New York and to the nonexclusive jurisdiction of the
United States District Court for the Southern District of New York, for the
purpose of any suit, action or other proceeding arising out of or based on this
Agreement or the subject matter hereof brought by ORBCOMM and (B) hereby waives
to the extent not prohibited by law, and agrees not to assert, by way of
motion, as a defense or otherwise, in any such proceeding, any claims that it
is not subject personally to the jurisdiction of the above-named courts, that
its property is exempt or immune from attachment or execution, that any such
proceeding brought in one of the above-named courts is improper, or that this
Agreement or the subject matter hereof may not be enforced in or by such court.
Licensee hereby consents to service of process in any such proceeding in any
manner permitted by the laws of the State of New York and agrees that service
of process by international registered mail, return receipt requested, at the
address specified in or pursuant to Section 17(a)





                                       27

hereof is reasonably calculated to give actual notice.  Licensee agrees that at
ORBCOMM's request it will appoint an agent for service of process within the
State of New York.

         (e)              Force Majeure.  Neither party shall be held
responsible for failure or delay in performance or delivery if such failure or
delay is the result of an act of God, the public enemy, embargo, governmental
act, fire, accident, war, riot, strikes, inclement weather or other cause of a
similar nature that is beyond the control of the parties.  In the event of such
occurrence, this Agreement shall be amended by mutual agreement to reflect an
extension in the period of performance and/or time of delivery.  Failure to
agree on an equitable extension shall be considered a claim or controversy and
resolved in accordance with Section 15.

         (f)              Waiver.  It is understood and agreed that no failure
or delay by either ORBCOMM or Licensee in exercising any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, power or privilege hereunder.  No waiver of any
terms or conditions of this Agreement shall be deemed to be a waiver of any
subsequent breach of any term or condition.  All waivers must be in writing and
signed by the party sought to be bound.

         (g)              Severability.  If any part of this Agreement shall be
held unenforceable, the remainder of this Agreement will nevertheless remain in
full force and effect.

         (h)              Headings.  Headings in this Agreement are included
for convenience of reference only and shall not constitute a part of this
Agreement for any other purpose.

         (i)              Independent Contractors.  Licensee and ORBCOMM are
independent contractors to one another, neither party has the authority to bind
the other in any way or to any third party, and nothing in this Agreement shall
be construed as granting either party the right or authority to act as a
representative, agent, employee or joint venturer of the other.

         (j)              Non-Disclosure.  Each of the parties to this
Agreement acknowledge the execution of the Mutual Non-Disclosure Agreement
dated as of October 10 1996 and each agrees to observe the provisions thereof.

         (k)              English Language; Communication in English.  The
parties recognize and agree that while this Agreement may be translated into
other languages, the English language version of this Agreement shall be the
official version of this Agreement and shall prevail if any dispute in the
interpretation of this Agreement between such languages arises between the
parties.  The parties agree that all communications, notices or any written
material to be provided by ORBCOMM to Licensee or by Licensee to ORBCOMM under
this Agreement shall be in the English language or accompanied by an accurate
and complete translation into English.

         (l)              Calendar.  The Gregorian calendar shall be used in
calculating, invoicing and paying all amounts due under this Agreement.

         (m)              Payments.  All payments due and payable to ORBCOMM
hereunder shall be paid in U.S. Dollars in immediately available funds to the
bank account specified by ORBCOMM in writing.  ORBCOMM shall have the right to
require Licensee to make a cash deposit or to provide ORBCOMM with an
irrevocable letter of credit in favor of ORBCOMM issued by a bank reasonable
acceptable to ORBCOMM.

         (n)              Equitable Relief.  Each of the parties acknowledges
that the ORBCOMM System and the ORBCOMM Services provided pursuant to this
Agreement are unique and recognizes and affirms that in the event of any breach
of this Agreement by it, money damages may not be adequate and the other party
may have no adequate remedy at law.  Accordingly, each of the parties agrees
that the other party shall have the right, in addition to any other rights and
remedies existing in its favor, to enforce its rights and the other party's
obligations hereunder not only by an action or actions for damages but also an
action or actions for specific performance, injunctive relief and/or other
equitable relief.

         (o)              Taxes.  All payments owed by Licensee hereunder shall
be made free and clear of any deductions or withholding for taxes,
contributions or otherwise and of any liability thereof. In the event Licensee
is required by the laws of any applicable Governmental Authority to withhold
any amount from any payment made hereunder, the relevant amount payable shall
be increased by such amount as is necessary to make the actual amount received
by ORBCOMM after such withholding equal to the amount that would have been
received had no withholding been required, and Licensee shall make such
withholding and pay the amount withheld to the relevant taxation authority.
Licensee shall obtain from the applicable Governmental Authority and forward to
ORBCOMM a certificate of payment of such withholding tax or deduction in such
form as shall be acceptable to the tax authorities having jurisdiction over

         extent ORBCOMM is obligated to do so, assisting Licensee in the
         maintenance and repair of the Licensee System; provided that, in
         either event, ORBCOMM shall use all good faith efforts to minimize its

                 In addition, if Licensee provides ORBCOMM Services directly to
         Subscribers, include provisions in its contracts or agreements with
         each of its Subscribers for the Licensee System substantially
         identical to the following:

                          (A)  In no event shall any of ORBCOMM Entities have
                 any obligation or liability to such Subscriber and such
                 Subscriber shall have no claim or right against any of the
                 ORBCOMM Entities for loss of use, revenue or profit or for any
                 other indirect, incidental or consequential damages;

                          (B)     In no event shall any of the ORBCOMM Entities
                 have any obligation or liability to such Subscriber and such
                 Subscriber shall have no claim or right against any of the
                 ORBCOMM Entities in an amount that exceeds in the aggregate
                 the actual amount of any [CONFIDENTIAL TREATMENT];

                 (xi)     Use the ORBCOMM Licensed Gateway Software only in
         accordance with the terms and conditions set forth in the ORBCOMM
         Gateway Software License Agreement;

                 (xii)    So long as such Subscriber Communicator complies with
         all standards of the European Telecommunications Standards Institute,
         if applicable, not discriminate against any Subscriber because such
         Subscriber purchased or obtained its Subscriber Communicator from one
         source versus another, and not offer service to Subscribers who buy or
         lease their Subscriber Communicators from Licensee or an Affiliate of
         Licensee at a price that is lower than that at which similar ORBCOMM
         Services are offered to Subscribers who obtain their Subscriber
         Communicators from another source;

                 (xiii)   To the extent permitted by law and except as
         permitted in Sections 2(b)(ii) and 7, (A) not register on the Licensee

         territory of any one other ORBCOMM System service licensee.  During
         the term of this Agreement, on the anniversary date of the execution
         of this Agreement, Licensee shall provide ORBCOMM with an officer's
         certificate certifying its compliance with the terms of this Section
         3(a)(xiii);

                 (xiv)    In the event a reseller of another ORBCOMM service
         licensee desires to be a reseller in the Territory, such reseller
         shall apply to Licensee to become a Licensee-approved reseller in the
         Territory; provided that such reseller meets the same standards and
         requirements as other approved resellers in the Territory then
         Licensee shall be required to offer to provide service to such
         reseller, at substantially the same rates, terms and conditions (in
         each case so long as such standards, requirements, terms and
         conditions are not designed to specifically exclude a reseller of
         another ORBCOMM service licensee) as it offers other, similar
         resellers of the ORBCOMM Services in the same country in the
         Territory, or if there are no similar resellers in such country, then
         at rates, terms and conditions that are commercially reasonable.  In
         the event Licensee does not believe such reseller will meet the
         standards or agree to abide by such rates, terms and

         determination, specifying in detail the basis for its conclusion.
         Thereafter, the parties shall discuss the reasons detailed by Licensee
         in such notice; provided that if ORBCOMM and Licensee are unable to
         mutually agree on the ability of such reseller to become a
         Licensee-approved reseller in the Territory, [CONFIDENTIAL
         TREATEMENT];

                 (xvi)    Promptly advise ORBCOMM in writing if Licensee or any
         of its Affiliates is a Reseller or acquires any direct or indirect

         withheld, all proposed or previously executed Reseller Agreements, and
         any amendments or modifications thereto, with such Reseller, together
         with an explanation and justification of the terms and conditions set
         forth therein;

                 (xvii)   Prior to the commencement of the provision of ORBCOMM
         Services in the Territory and within 30 days after the end of each
         calendar year thereafter, provide to ORBCOMM in writing a full

         the pricing strategy and the prices serve the purpose of maximizing
         revenues over the term of and consistent with or greater than the

         TREATMENT] prepared by or on behalf of Licensee, a copy of which is

         Services have been appropriately priced, when combined with other
         services or hardware provided by Licensee or its Resellers, and
         accounted for in calculating gross operating revenues pursuant to
         Section 5(a).  Such pricing policies and strategies are not subject to
         [CONFIDENTIAL TREATMENT] and Licensee shall be obligated to disclose
         to ORBCOMM the identity of its Resellers but shall not be obligated to
         disclose to ORBCOMM the identity of its or its Reseller's Subscribers;

                 (xviii)  Establish a mutually agreeable framework and
         reporting scheme with ORBCOMM for the joint exchange of operational
         statistics (such as statistical data on message lengths, message
         frequencies, time of day, day of week and seasonal usage for each
         service offering and market segment served by Licensee) that are
         necessary for the Licensee, ORBCOMM and other ORBCOMM System service
         licensees to appropriately manage their respective systems and provide
         consistent quality services using the ORBCOMM System;

                 (xix)    Participate with ORBCOMM in the preparation of

         taxes owed on behalf of ORBCOMM), that arise from the performance of
         its duties under this Agreement, including the payment of all fees and
         other amounts due and owing hereunder, provided that in no event shall
         Licensee be responsible for the payment of any incomes taxes owed by
         ORBCOMM on amounts due and payable by Licensee hereunder;

                 (xxii)   From three months after the System Available Date,

         any such configuration change; and provided further that version
         changes to the ORBCOMM Licensed Gateway Software shall occur in

         (b)     Responsibilities of ORBCOMM.  ORBCOMM shall:

                 (i)      Cooperatively work with and encourage the

         functions of the Licensee System are operating properly and in a
         manner compatible with the ORBCOMM System;

         provided that written data that exists or that ORBCOMM can readily
         compile from existing data shall be provided at ORBCOMM's expense and
         other written data or any data required to be presented in person or
         orally shall be provided at Licensee's expense; and provided further

         facsimile or an ORBCOMM-approved secure email system and the advice
         may be provided by ORBCOMM using such similar means, with all
         communications conducted in the English language; provided that if, in
         ORBCOMM's business discretion, the nature of these requests or their
         frequency indicate that Licensee's operators or technicians are
         technically inadequate for their tasks, ORBCOMM may require that these
         employees be retrained (or, at Licensee's option, replaced) at
         Licensee's cost, or ORBCOMM may charge for this advice in accordance
         with Section 8(b) of the Ground Segment Procurement Contract; and
         provided further that, until three months after the System Available
         Date, ORBCOMM shall only be obligated to have available emergency

         reporting scheme with Licensee for the joint exchange of operational
         statistics (such as statistical data on message lengths, message
         frequencies, time of day, day of week and seasonal usage for each
         service offering and market segment served by Licensee) that are
         necessary for the Licensee, ORBCOMM and other ORBCOMM System service
         licensees to appropriately manage their respective systems and provide
         consistent quality services using the ORBCOMM System;

                 (x)      Not change the ORBCOMM System or the ORBCOMM Licensed
         Gateway Software so as to render technically inoperable (A) any
         Subscriber Communicators registered on the Licensee System or (B) any
         [CONFIDENTIAL TREATMENT];

                 (xi)     To the fullest extent permitted by applicable law,
         rule or regulation of any Governmental Authority, include language
         substantially similar to Section 3(a)(xiii) in each service license
         agreement it executes after the date hereof and, [CONFIDENTIAL
         TREATEMENT].  Except as specifically provided in this Section
         3(b)(xii), ORBCOMM shall have no other obligations or liabilities to
         Licensee for a violation of such provision by another ORBCOMM System

         type approval testing standard designed to demonstrate compliance with
         such ETSI standards so long as the ETSI standards are consistent with
         the technical capabilities of the ORBCOMM System; and

                 (xiii)   Provide Licensee with any and all amendments or
         modifications to the FCC licenses received by Orbital Communications
         Corporation, ORBCOMM Global or any of their Affiliates, as the case
         may be, relating to the ORBCOMM System and give Licensee notice
         promptly after filing of any amendment or modification application
         filed with the FCC relating to the ORBCOMM System.

         (a)     In addition to any other fees or payments specified herein,
Licensee shall pay to ORBCOMM the sum of U.S.  [CONFIDENTIAL TREATMENT] (the

         [CONFIDENTIAL





                                    Page 15

         TREATMENT] and shall be payable in cash or immediately available funds
         on [CONFIDENTIAL TREATMENT];

                 (iii)    The third installment shall be in the amount of

         The parties acknowledge that a non-refundable option fee in the amount
         of U.S. [CONFIDENTIAL TREATMENT] has been fully paid to ORBCOMM Global
         by Nuova Telespazio, a shareholder of Licensee, on behalf of Licensee
         prior to the execution of this Agreement.  Such amount was paid in
         consideration of the extension, until August 1, 1996, of the exclusive
         right of the founder of Licensee to be the Candidate Licensee for
         ORBCOMM Services in Europe.

         such amounts. The parties agree that the foregoing shall be the sole
         and exclusive remedy of Licensee for any failure by ORBCOMM
         [CONFIDENTIAL TREATMENT].

                 (a)      Amount of Fee.  (i)  The Satellite Usage Fee for a
         calendar month shall be equal to the greater of (A) [CONFIDENTIAL
         TREATMENT] percent (the "Revenue Dependent Fee Percentage") of
         Licensee's gross operating revenues for such month (the "Revenue
         Dependent Amount") and (B) U.S. [CONFIDENTIAL TREATMENT] (the "Data
         Throughput Fee Amount") multiplied by the number of KBytes of data
         originating from or terminating to Subscriber Communicators registered
         on or provided roaming services by the Licensee System at any time
         during such month and processed by Licensee's ORBCOMM Gateway (the
         "Data Throughput Fee"), in either case excluding bytes added





                                    Page 16
<PAGE>   17
         to the Subscriber's message by the ORBCOMM System and excluding the OR
         address indicator.

                 (ii)     For purposes of this Agreement, in calculating the
Revenue Dependent Amount gross operating revenues shall:

                          (A)     be calculated using the amounts invoiced
                 during a calendar month by Licensee, whether these amounts are
                 collected or not;

                          (B)     include only revenues derived from
                 [CONFIDENTIAL TREATMENT], [CONFIDENTIAL TREATMENT], and
                 [CONFIDENTIAL TREATMENT] for ORBCOMM Services, including all
                 [CONFIDENTIAL TREATMENT] and [CONFIDENTIAL TREATMENT] derived
                 as a provider of roaming or multinational account services and
                 all [CONFIDENTIAL TREATMENT], [CONFIDENTIAL TREATMENT] and
                 [CONFIDENTIAL TREATMENT] charged by Licensee to an In-Country
                 Representative;

                          (C)     if such a long message surcharge has not been
                 charged Resellers and Subscribers, in the event Licensee
                 provides services directly to Subscribers, be calculated to
                 include a long message surcharge, equal to at least
                 U.S.[CONFIDENTIAL TREATMENT] (or its equivalent in the
                 applicable currency) for each message whose length is between
                 [CONFIDENTIAL TREATMENT] and [CONFIDENTIAL TREATMENT] bytes,
                 inclusive, or equal to at least U.S.  [CONFIDENTIAL TREATMENT]
                 (or its equivalent in the applicable currency) for each
                 message whose length exceeds [CONFIDENTIAL TREATMENT] bytes;

                          (D)     be calculated assuming that ORBCOMM Services
                 combined with other services or hardware provided by Licensee
                 or its Resellers were priced no less than similar ORBCOMM
                 Services provided on a stand alone basis;

                          (E)     exclude those revenues derived from another
                 third party derived as a provider of roaming or multinational
                 account services and any surcharge due and owing to ORBCOMM in
                 connection with roaming or multinational account services; and

                          (F)     exclude all value-added or similar taxes or
                 assessments that Licensee is required by applicable law to
                 collect from its customers and remit to Governmental
                 Authorities in the Territory.

                 (iii)    In calculating the Revenue Dependent Amount or the
         Data Throughput Fee any data throughput associated with a Subscriber
         Communicator registered or used by any of ORBCOMM Global, ORBCOMM USA,
         or ORBCOMM for purposes of maintenance and testing shall be excluded.

                 (iv)     The Data Throughput Fee Amount shall be reviewed by
         the parties on the [CONFIDENTIAL TREATMENT] anniversary of the
         Licensee System Acceptance Test and





                                    Page 17
<PAGE>   18
         annually thereafter for the purposes of determining whether, taking
         into account competition and other market conditions, it should be
         [CONFIDENTIAL TREATMENT].  In addition, Licensee may request that the
         Data Throughput Fee Amount be reviewed by the parties more frequently
         on an industry-by-industry basis in light of market specific
         competition or other relevant considerations.

                 (b)      [CONFIDENTIAL TREATMENT].  (i) If at no time prior to
         [CONFIDENTIAL TREATMENT] were there at least [CONFIDENTIAL TREATMENT]
         in orbit, commencing on [CONFIDENTIAL TREATMENT] or [CONFIDENTIAL 
         TREATMENT] ORBCOMM shall [CONFIDENTIAL TREATMENT] an amount equal to 
         [CONFIDENTIAL TREATMENT] per month, [CONFIDENTIAL TREATMENT] until the
         earlier of (x) [CONFIDENTIAL TREATMENT] and (y) [CONFIDENTIAL 
         TREATMENT].  Such [CONFIDENTIAL TREATMENT] in each month in an amount 
         equal to the lesser of (A) [CONFIDENTIAL TREATMENT] and (B) 
         [CONFIDENTIAL TREATMENT].

                (ii)      [CONFIDENTIAL TREATMENT] ORBCOMM shall [CONFIDENTIAL 
         TREATMENT] an amount, equal to the lesser of (A) [CONFIDENTIAL 
         TREATMENT] a month and (B) [CONFIDENTIAL TREATMENT] for such month,
         provided that the [CONFIDENTIAL TREATMENT] shall be [CONFIDENTIAL 
         TREATMENT].  In the event [CONFIDENTIAL TREATMENT] shall be 
         [CONFIDENTIAL TREATMENT] and thereafter, [CONFIDENTIAL TREATMENT].

                 (iii)    WITHIN [CONFIDENTIAL TREATMENT] calendar days of the 
         end of each calendar month, ORBCOMM shall compute and invoice
         Licensee for the actual Satellite Usage Fee payment for such month, in
         U.S. dollars, using the official exchange rate in effect at Morgan
         Guaranty Trust Company of New York at the close of business in New
         York on the last business day of such calendar month. In calculating
         the amount owed by Licensee hereunder, ORBCOMM shall take into account
         any [CONFIDENTIAL TREATMENT].  In the event that Licensee does not
         provide ORBCOMM with any of the foregoing information, ORBCOMM may
         make its own estimate thereof, which estimate shall be conclusive and
         binding on Licensee, and compute the amount to be invoiced using such
         estimate.

                 (iv)     Within [CONFIDENTIAL TREATMENT] days of the receipt
         of the Satellite Usage Fee invoice, Licensee shall pay the Satellite
         Usage Fee by electronic fund transfer to the bank account specified by
         ORBCOMM.  All Satellite Usage Fees remaining unpaid after such
         [CONFIDENTIAL TREATMENT] day period shall bear interest until paid at
         the rate equal to one and one-half times the prime rate or rates
         announced by Morgan Guaranty Trust Company of New York during the
         period of nonpayment.

                 (v)      Subject to Section 9(b)(ii)(F), if payments due under
         this Section 5 cannot be made as provided herein due to [CONFIDENTIAL
         TREATMENT] or other [CONFIDENTIAL TREATMENT] in each and every country
         or territory within the Territory, ORBCOMM shall permit Licensee to
         [CONFIDENTIAL TREATMENT] for a period of [CONFIDENTIAL TREATMENT]
         years.

SECTION 6 - SUBSCRIBER MANAGEMENT AND CUSTOMER SUPPORT SYSTEM

         To the fullest extent permitted by law, the parties to this Agreement
acknowledge and agree that it is critical that (a) in the universal
commissioning of new applications using the ORBCOMM System, Licensee and other
ORBCOMM System service licensees have a billing and customer support system
that can adequately and appropriately bill and manage Resellers and Subscribers
for such applications, as well as provide associated customer support
functions, and (b) Multinational Accounts be established.  It is essential,
therefore, that Licensee obtain a license from CSC Intelicom, Inc. ("CSC") for
the subscriber management and customer support system software (the "Subscriber
Management and Customer Support Software") Licensee will use for ORBCOMM
Services using the Licensee System.  Licensee hereby agrees to obtain a license
for the Subscriber Management and Customer Support Software and purchase
certain hardware from CSC on substantially the terms and conditions specified
in the Software License Agreement attached hereto as Attachment H (the "CSC
Software License Agreement"), as such agreement may be modified by mutual
agreement of CSC and Licensee.


SECTION 7 - ROAMING ARRANGEMENTS AND MULTINATIONAL ACCOUNTS

         ORBCOMM shall establish an International Marketing Council, which
Council shall include all ORBCOMM System service licensees.  The International
Marketing Council shall consider, among other things, the terms and conditions
on which roaming arrangements and multinational accounts shall be established
for ORBCOMM System service licensees. Licensee and ORBCOMM agree to be bound by
the determinations of the International Marketing Council with respect to
roaming arrangements and multinational accounts.

SECTION 8 - PROPER OPERATION OF THE LICENSEE SYSTEM

         (a)     Performance of Tests.  (i)  Once a calendar year, Licensee
shall permit ORBCOMM and/or its representatives access to the Licensee System,
other than the Subscriber Management and Customer Support Software and
associated hardware, for the purpose of performing and to the extent required
to perform a quality inspection (the "Quality Inspection"), which shall be
conducted to determine compliance with the provisions of this Agreement.  The
Quality Inspection (A) may be conducted only after ORBCOMM has given the
Licensee fifteen days prior written notice thereof, (B) shall be conducted in a
way that minimizes the interference with Licensee's normal business operations,
and (C) may include a Licensee System Acceptance Test that requires some
assistance from Licensee's personnel.  All costs of Quality Inspections, other
than the costs, including any out-of-pocket expenses, associated with the
assistance received by ORBCOMM from Licensee's personnel specified in clause
(C) above, shall be borne by ORBCOMM; provided, however that if the Quality
Inspection demonstrates that the Licensee System is not operating in accordance
with the Licensee System Acceptance Specifications, Licensee shall bear the
cost of such Quality Inspection which shall be at the rate for On-Site
Technical Assistance Services set forth in Section 8(a) of the Ground Segment
Procurement Contract.





                                    Page 19
<PAGE>   20
         (ii)    In addition to the foregoing, if, subsequent to the initial
Licensee System Acceptance Test, in ORBCOMM's reasonable opinion after
consulting with Licensee, there are grounds to believe that the Licensee System
is not operating in accordance with the Licensee System Acceptance
Specifications, ORBCOMM shall be entitled, at its option, (A) to require
Licensee to perform a Licensee System Acceptance Test or (B) to perform a
Licensee System Acceptance Test itself.  If ORBCOMM elects to require Licensee
to take the action specified in (A) above, ORBCOMM shall advise Licensee in
writing of such election and Licensee must perform, or have performed, the test
within ten days thereafter.  If ORBCOMM elects to perform the Licensee System
Acceptance Test itself, ORBCOMM shall advise Licensee in writing of such
election and Licensee shall provide ORBCOMM and its representatives access to
Licensee's facilities, including its equipment to the extent reasonably
necessary to perform the test.  The cost to perform the Licensee System
Acceptance Test shall be borne solely by Licensee and, if performed by ORBCOMM,
shall be at the rate for On-Site Technical Assistance Services set forth in
Section 8(a) of the Ground Segment Procurement Contract; provided that, if
after completion of such test, ORBCOMM reasonably concludes that (x) the reason
the Licensee System was not operating in accordance with the Licensee System
Acceptance Specifications was the result of a defect in the ORBCOMM Gateway
covered by the warranty provisions set forth in Section 6 of the Ground Segment
Procurement Contract or (y) the Licensee System is operating in accordance with
the Licensee System Acceptance Specifications, the cost of the Licensee System
Acceptance Test including Licensee's out-of-pocket costs in connection
therewith, shall be borne by ORBCOMM.

         (b)     Corrective Action.  If ORBCOMM determines from the Licensee
System Acceptance Test that the Licensee System is not operating in accordance
with the Licensee System Acceptance Specifications, or that the Licensee System
is operating in violation of any applicable law, rule or regulation of any
Governmental Authority and such law, rule or regulation requires immediate
cessation of operation, ORBCOMM shall be entitled to require Licensee
immediately to cease operation of the Licensee System and, if Licensee fails to
cease operation of the Licensee System, ORBCOMM shall be entitled to terminate
Licensee's access to the ORBCOMM System until ORBCOMM determines that all
necessary corrections have been made by Licensee; provided however, that, if
only a portion of the Licensee System is not operating in accordance with the
Licensee System Acceptance Specifications, or only a portion of the Licensee
System is operating in violation of any such law, rule or regulation, and
ORBCOMM determines that cessation of the non-conforming portion only of the
Licensee System will not injure the ORBCOMM System, is technically consistent
with the ORBCOMM System architecture and is operationally feasible, ORBCOMM
shall notify Licensee in writing of such determination and Licensee shall be
entitled to cease operating the non-conforming portion only of the Licensee
System.  Notwithstanding the foregoing proviso, in the event the corrections
required by this Section 8 are not made within three months of receipt by
Licensee of written notice thereof, ORBCOMM shall be entitled to terminate this
Agreement.

SECTION 9 - TERM OF AGREEMENT

         (a)     Term.  Subject to the provisions set forth in this Section 9,
this Agreement shall have a term of ten years, commencing on the date on which
ORBCOMM provides Licensee with a Licensee System Acceptance Test certificate
certifying completion of the Licensee System Acceptance Test for the ORBCOMM
Gateway for the Territory that includes one GES.  Within one year prior to the
expiration of the initial term of this Agreement, Licensee may request that
this Agreement be extended for a further period of up to ten years, which
request shall not be unreasonably denied by ORBCOMM.  To the extent such
extension is granted, ORBCOMM shall not charge Licensee a license fee in any
form for such extension.

         (b)     Termination.

         (i)     Termination by Licensee.  Subject to the provisions of Section
12, this Agreement may be terminated for convenience by Licensee one year after
providing to ORBCOMM written notice of termination (a "Termination for
Convenience").  In addition, this Agreement may be terminated by Licensee at
any time after the occurrence of any of the following events of default:

                 (A)      Any representation or warranty made by ORBCOMM in
         this Agreement or any other document delivered pursuant to this
         Agreement including the Ground Segment Procurement Contract and the
         ORBCOMM Gateway Software License Agreement shall be false or
         misleading in any material respect;

                 (B)      ORBCOMM shall fail to observe or perform any of its
         obligations under this Agreement (other than breaches specified in
         Section 9(b)(i)(E)), and such failure shall remain uncured for a
         period of [CONFIDENTIAL TREATMENT] days after receipt by ORBCOMM of
         written notice thereof;

                 (C)      ORBCOMM shall (w) make an assignment for the benefit
         of creditors, (x) file a petition in bankruptcy, (y) be adjudicated
         insolvent or bankrupt, or (z) petition or apply to any tribunal for
         any receiver or for any trustee for it under any domestic or foreign
         reorganization, arrangement, readjustment of debt, dissolution or
         liquidation law or statute or ORBCOMM shall have commenced against it
         any such proceeding or an order for relief shall be entered that
         remains undismissed for a period of [CONFIDENTIAL TREATMENT] days,
         ORBCOMM by any act indicates its consent to, approval of, or
         acquiescence in, any such proceeding, order for relief or the
         appointment of any receiver of or any trustee for it or ORBCOMM
         suffers any such receivership or trusteeship to continue undischarged
         for a period of [CONFIDENTIAL TREATMENT] days;

                 (D)      Licensee shall have exercised its rights set forth in
         Section 13(a);

                 (E)      ORBCOMM shall fail to comply in all material respects
         with all applicable laws, rules and regulations of any Governmental
         Authority in the performance of its obligations hereunder or under any
         of the other Transaction Agreements and such failure shall remain
         uncured for a period of [CONFIDENTIAL TREATMENT] days after receipt by





                                    Page 21

         ORBCOMM of written notice thereof, provided that if ORBCOMM diligently
         and in good faith attempted to cure such failure during such
         [CONFIDENTIAL TREATMENT] day period but was unable to resolve such
         failure, ORBCOMM shall have an additional [CONFIDENTIAL TREATMENT]
         days to cure such failure; or

                 (F)      An event of default by ORBCOMM shall have occurred
         under Section 9(a) of the Ground Segment Procurement Agreement or
         under Section 7(a) of the ORBCOMM Gateway Software License Agreement.

         (ii)    Termination by ORBCOMM.  This Agreement may be terminated by
ORBCOMM at any time after the occurrence of any of the following events of
default:

                 (A)      Licensee shall fail to pay any amount due under this
         Agreement, including the Satellite Usage Fee, within [CONFIDENTIAL
         TREATMENT] days after receipt of notice from ORBCOMM that such amount
         is due;

                 (B)      Any representation or warranty made by Licensee in
         this Agreement or any other document delivered pursuant to this

         ORBCOMM Gateway Software License Agreement shall be false or
         misleading in any material respect;

                 (C)      Licensee shall fail to observe or perform any of its
         obligations under Section 8(b);

         because of currency exchange restrictions imposed by each Governmental
         Authority in the Territory;

                 (G)      Licensee shall take any action or fail to take any
         action that results in





                                    Page 22
<PAGE>   23
         ORBCOMM contravening or violating any law, rule or regulation of any
         Governmental Authority, or Licensee shall fail to comply in all
         material respects with all applicable laws, rules and regulations of
         any Governmental Authority in the performance of its obligations
         hereunder or under any of the other Transaction Agreements and such

         least one of [CONFIDENTIAL TREATMENT] or the [CONFIDENTIAL TREATMENT];
         or

                 (J)      An event of default by Licensee shall have occurred
         under Section 9(b) of the Ground Segment Procurement Agreement,
         Section 7(b) of the ORBCOMM Gateway Software License Agreement, or
         under the CSC Software License Agreement.

         (iii)   Special Termination By Licensee.  (A) Licensee shall be
entitled to terminate this Agreement in the event it determines by
[CONFIDENTIAL TREATMENT] that the standards expected to be adopted by ETSI
will, if adopted, preclude the technical operation of the ORBCOMM System in the
Territory.  If Licensee desires to terminate this Agreement pursuant to this
Section 9(b)(iii) Licensee must give ORBCOMM written notice prior to
[CONFIDENTIAL TREATMENT] of Licensee's exercise of its right to terminate this
Agreement effective immediately.  In the event of termination by Licensee

         (c)     Remedies on Termination.  (i)  On a Termination for
Convenience or a termination of this Agreement by ORBCOMM pursuant to Section
9(b)(ii), to the fullest extent permitted by law, ORBCOMM shall be entitled, in
its discretion, to become a sublicensee of Licensee and operate and manage the
Licensee System for a period of up to [CONFIDENTIAL TREATMENT] after
termination of this Agreement to ensure that there is as little interruption as
possible in the provision of ORBCOMM Services in the Territory and, during such
[CONFIDENTIAL TREATMENT] period, ORBCOMM shall use all commercially reasonable
efforts to locate a third party buyer for the Licensee System.  Licensee agrees
to cooperate in a commercially reasonable manner and





                                    Page 23
<PAGE>   24
actively participate, including with respect to the transfer of the Permits in
the Territory and providing ORBCOMM information on its Resellers, in ensuring
continued operations until such time that a new entity has been granted the
necessary Permits for the Territory and is ready to start operations.

         (ii)    Subject to Section 14, termination of this Agreement by the
party not in default in accordance with the terms hereof shall be without
prejudice to any other rights or remedies such party shall have by law.

         (d)     Abandonment of ORBCOMM System.  (i)  Nothing contained in this
Agreement, including any attachments hereto, shall prevent the ORBCOMM Entities
from ceasing to develop, construct or operate the ORBCOMM System.  In the event
ORBCOMM or any of the ORBCOMM Entities abandon the ORBCOMM System by ceasing to
develop, construct and operate all of the ORBCOMM System, ORBCOMM shall be
entitled to terminate this Agreement by giving Licensee 180 days written
notice.  In such event, to the fullest extent permitted by applicable law,
Licensee shall have the right, together with all other persons who may have a
similar right and a desire to exercise such right, all of whom shall be
obligated to act as a group (the "ORBCOMM System Purchase Group"), to purchase
the tangible assets of the ORBCOMM System owned by ORBCOMM Global, ORBCOMM USA,
or ORBCOMM and to purchase a non-exclusive, perpetual license to use, solely in
connection with the operation of the tangible assets purchased pursuant to this
Section 9(d), the intangible assets of the ORBCOMM System, other than any
operating or regulatory licenses with respect to the ORBCOMM System, owned by
ORBCOMM Global, ORBCOMM USA, or ORBCOMM at their then fair market value, which
right shall be exercised, if at all, by the ORBCOMM System Purchase Group
within three months of receipt of written notice from ORBCOMM of abandonment
(the "Option Exercise Notice").  The fair market value of the tangible assets
and such license for the intangible assets of the ORBCOMM System shall be
determined as of the day of abandonment and on the basis of an arms' length
transaction between a willing buyer and a willing seller.  Any determination of
fair market value pursuant to this Section 9(d) shall be final, binding and
conclusive on the parties.  Fair market value shall be determined as follows:

                 (A)      Promptly after delivery of the Option Exercise
         Notice, ORBCOMM and the ORBCOMM System Purchase Group shall attempt in
         good faith to agree on the fair market value.  If ORBCOMM and the
         ORBCOMM System Purchase Group agree on a value (regardless of when
         such agreement is reached, and notwithstanding the pendency of
         appraisal efforts pursuant to this Section), such value shall be the
         fair market value;

                 (B)      If ORBCOMM and the ORBCOMM System Purchase Group fail
         to reach such an agreement within one month after the delivery of the
         Option Exercise Notice, they shall each select an independent
         appraiser who is one of the "Big Six" United States accounting firms.
         If either ORBCOMM or the ORBCOMM System Purchase Group shall fail to
         select an appraiser within twenty (20) days after the expiration of
         the one-month period referred to in the preceding sentence, the fair
         market value shall be determined by the appraiser selected by the
         other.  Following such selection, each such appraiser shall determine
         the value of the tangible and intangible assets of the ORBCOMM System
         to





                                    Page 24
<PAGE>   25
         be purchased pursuant to this Section 9(d) as quickly as practicable,
         and in any event within forty-five (45) days after the last appraiser
         has been selected, and give notice of such determination to ORBCOMM
         and the ORBCOMM System Purchase Group.  If either appraiser shall fail
         to make such a determination of value within forty-five days after the
         last appraiser has been selected, the fair market value shall be the
         value determined by the other appraiser.  If the greater of the two
         values determined by such two appraisers is within 10% of the lesser
         of such two values, the fair market value shall be the average of such
         two values.

                 (C)      If the greater of the two values determined by such
         two appraisers is not within 10% of the lesser of such two values,
         such two appraisers shall select a third independent appraiser who
         shall be one of the "Big Six" United States accounting firms and who
         shall as quickly as practicable, but in no event later than forty-five
         days after appointment, select one of the values determined by the
         first two appraisers as the value that more closely approximates the
         correct fair market value, and such value selected by the third
         appraiser shall be fair market value.

                 (D)      ORBCOMM and the ORBCOMM System Purchase Group agree
         to cooperate with one another and with the appraisers in determining
         fair market value. ORBCOMM and the ORBCOMM System Purchase Group shall
         each bear its own out-of-pocket expenses incurred in connection with
         the determination of fair market value, including without limitation
         the fees and expenses of the appraiser selected by each, and one-half
         of the fees and expenses of the third appraiser, if any.

                 (E)      The consummation of the purchase and sale of the
         assets specified herein shall occur within 45 days of the
         determination of the fair market value therefor.

         In the event ORBCOMM ceases to develop, construct or operate the
         ORBCOMM System as specified in this Section 9(d)(i), ORBCOMM shall use
         all commercially reasonable efforts to cooperate with the ORBCOMM
         System Purchase Group in the transfer of  the ORBCOMM System; provided
         that ORBCOMM shall be reimbursed by the ORBCOMM System Purchase Group
         for all of its expenses incurred in providing such cooperation.  In
         addition, ORBCOMM shall continue to operate the ORBCOMM System until
         the expiration of any rights to purchase by the ORBCOMM System
         Purchase Group if the ORBCOMM System Purchase Group does not exercise
         such rights or, if the ORBCOMM System Purchase Group exercises such
         rights, until consummation of the purchase and sale of the assets as
         specified herein.

         [CONFIDENTIAL TREATMENT].

         (e)     Use of ORBCOMM System After Termination or Expiration.  Except
as otherwise provided in Section 9(d), on the effective date of termination or
expiration of this Agreement, Licensee shall cease using the ORBCOMM System,
the ORBCOMM Licensed Gateway Software, the ORBCOMM operating methods and the
"ORBCOMM" logos, trademarks, service marks and name, and shall return all
manuals and related materials to ORBCOMM.

using radio frequencies below 1 GHz for communications directly between
satellite(s) and subscriber communicators.

         (b)     After Term.  In the event of a Termination for Convenience, or
if ORBCOMM

terminates this Agreement pursuant to Section 9(b)(ii), Licensee hereby agrees

         (a)     In the event ORBCOMM is unable to provide Licensee with access
to the ORBCOMM System due to temporary or intermittent problems (not including
planned periods of satellite unavailability) with the ORBCOMM System other than
those temporary or intermittent problems caused by Licensee, any of its
Subscribers or the Licensee System (an "Intermittent Service Problem") for an
aggregate of more than ten days where no service was available for a 24
consecutive hour period during any one year period commencing on the later to
occur of (i) the System Available Date and (ii) the date the Licensee System
commenced operations, and any anniversary of such date, Licensee's sole and
exclusive remedy shall be to extend the term of this Agreement [CONFIDENTIAL
TREATMENT] for each day, in excess of such ten days where no service was
available for a 24 consecutive hour period, that ORBCOMM is unable to provide
Licensee with access to the ORBCOMM System; provided, however that if the
ORBCOMM System has Intermittent Service Problems aggregating 180 days where no
service was available for a 24 consecutive hour period in each of three

THIS AGREEMENT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, NONE OF THE
ORBCOMM ENTITIES HAVE MADE AND NONE OF THEM SHALL BE DEEMED TO HAVE MADE ANY
REPRESENTATIONS OR WARRANTIES WHATSOEVER WITH RESPECT TO THE ORBCOMM SYSTEM OR
ANY SERVICES AND/OR PRODUCTS TO BE PROVIDED UNDER THIS AGREEMENT.  EXCEPT AS
EXPRESSLY PROVIDED IN THIS AGREEMENT, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH OF THE ORBCOMM ENTITIES EXPRESSLY DISCLAIMS, AND LICENSEE
HEREBY EXPRESSLY WAIVES, RELEASES AND RENOUNCES ALL OTHER WARRANTIES OF EACH OF
THE ORBCOMM ENTITIES, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH
RESPECT TO, INCLUDING, BUT NOT LIMITED TO, (i) ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; (ii) ANY IMPLIED WARRANTY
ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING OR USAGE OF TRADE; (iii)
ANY WARRANTIES AS TO THE ACCURACY, AVAILABILITY OR CONTENT OF THE ORBCOMM
SYSTEM OR ANY SERVICES AND/OR PRODUCTS PROVIDED BY OR THROUGH ANY OF THE
ORBCOMM ENTITIES UNDER THIS AGREEMENT; AND (iv) ANY WARRANTY  UNDER ANY THEORY
OF LAW, INCLUDING ANY TORT, NEGLIGENCE, STRICT LIABILITY, CONTRACT OR OTHER
LEGAL OR EQUITABLE THEORY.  NO REPRESENTATION OR OTHER AFFIRMATION OF FACT,
INCLUDING, BUT NOT LIMITED TO, STATEMENTS REGARDING CAPACITY OR SUITABILITY FOR
USE, THAT IS NOT CONTAINED IN THIS AGREEMENT SHALL BE DEEMED TO BE A WARRANTY
BY ANY OF THE ORBCOMM ENTITIES.

         (b)     Limitation of Liability.  (i)  Each of the parties
acknowledges and understands that the ORBCOMM System is a new, untested system
that entails a high degree of risk of (A) delay in or cancellation of
deployment and (B) launch vehicle, satellite and other equipment or software
failure or impaired performance, and that there can be no assurance that the
ORBCOMM System will be an economically viable system even if successfully
deployed.  Each party shall bear all responsibility, risk and cost associated
with developing and maintaining its respective business, and none of the
ORBCOMM Entities shall be liable to Licensee for costs or damages caused by any
schedule delays or failure of the ORBCOMM System or any component thereof,
except as specifically provided in this Agreement.

         (ii)    Licensee acknowledges that ORBCOMM shall supply the service
that is the subject of this Agreement on a good faith efforts basis and that
service failures and interruptions may occur and are difficult to assess as to
cause or resulting damages.  In such event and except as otherwise provided in
Section 13, the parties agree that the ORBCOMM Entities shall not be liable to
Licensee for any losses or damages arising out of any failure of performance,
error, omission, interruption, deletion, defect, delay in operation or
transmission, communications line failure, theft or destruction or unauthorized
access to, alteration of or use of records, associated with the ORBCOMM System
or ORBCOMM Services whether for breach of contract, tortious behavior,
negligence, or under any other cause of action.

         (iii)   NOTWITHSTANDING ANYTHING CONTAINED HEREIN TO THE CONTRARY, IN
NO EVENT SHALL EITHER PARTY HAVE ANY OBLIGATION, LIABILITY, RIGHT, CLAIM OR
REMEDY TO THE OTHER UNDER THIS AGREEMENT FOR LOSS OF USE, REVENUE OR PROFIT OR
FOR ANY OTHER INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.  In addition,
except as otherwise specified in Sections 5(b) and 9(d)(ii), in no event shall
any liability of ORBCOMM or any of the other ORBCOMM Entities under the
Transaction Agreements in the aggregate exceed an amount equal to [CONFIDENTIAL
TREATMENT] ([CONFIDENTIAL TREATMENT]) and U.S. [CONFIDENTIAL TREATMENT] minus
(A) [CONFIDENTIAL TREATMENT] and (B) [CONFIDENTIAL TREATMENT].


SECTION 15 - DISPUTE RESOLUTION

         (a)     Subject to the provisions of Section 18(n), in the event of a
claim or controversy regarding any matter covered by this Agreement, ORBCOMM
and Licensee shall use all reasonable efforts to resolve such claim or
controversy within 60 calendar days (5 calendar days in the case of a claim or
controversy arising under Section 3(a)(xiv)) of receipt by either party of
notice of the existence of any such claim or controversy.  In the event the
parties are unable to agree on the resolution of such claim or controversy
within such period of time, either party may remove the claim or controversy
for settlement by final and binding arbitration in New York, NY, in accordance
with the then existing United States domestic rules of the American Arbitration
Association ("AAA") (to the extent not modified by this Section).  In the event
that more than one claim or controversy arises under this Agreement, such claim
or controversy may be consolidated in a single arbitral proceeding.  The
arbitral tribunal shall be composed of three arbitrators.  Each of ORBCOMM and
Licensee shall appoint one arbitrator.  If any party shall fail to appoint an
arbitrator within 30 calendar days (15 calendar days in the case of a claim or
controversy arising under Section 3(a)(xiv)) from the date on which the other
party's request for arbitration has been communicated to the first party, such
appointment shall be made by the AAA.  The two arbitrators so appointed shall
agree upon the third arbitrator who shall act as chairman of the arbitral
tribunal and, other than with respect to a claim or controversy arising under
Section 3(a)(xiv), who shall have significant operational expertise in
geographically distributed data communications networks.  If the two appointed
arbitrators fail to nominate a chairman within ten calendar days (5 calendar
days in the case of a claim or controversy arising under Section 3(a)(xiv))
from the date as of which both arbitrators shall have been appointed, such
chairman shall be selected by the AAA.  With respect to a claim or controversy
arising under Section 3(a)(xiv), the arbitrators shall be obligated to render a
decision with respect thereto within 30 days of the date of the selection of
the chairman.  In all cases, the arbitrators shall be fluent in English.
Judgment upon any award rendered by the arbitrators may be entered in any court
having jurisdiction or application may be made for judicial acceptance of the
award and an order of enforcement, as the case may be.  The parties agree that
if it becomes necessary for any party to enforce an arbitral award by a legal
action or additional arbitration or judicial methods, the party against whom
enforcement is sought shall pay all reasonable costs and attorney's fees
incurred by the party seeking to enforce the award.

         (b)     Pending a final determination by the arbitrators, if the claim
or controversy





                                    Page 30
<PAGE>   31
concerns the payment by Licensee of any fees or amounts due hereunder
(including the right to conduct an audit of such fees or amounts), ORBCOMM
shall have the right to terminate Licensee's access to the ORBCOMM System
unless Licensee posts a bond from a reputable bonding company covering in full
the amount of the disputed payment.  In the event ORBCOMM elects to exercise
such right and notwithstanding any determination by the arbitrators, Licensee's
sole remedies for such termination by ORBCOMM shall be an extension of the term
of this Agreement equal to the period during which Licensee was denied access
to the ORBCOMM System and in the event the arbitrators determine that Licensee
did not owe ORBCOMM any fees or amounts and Licensee posted a bond as specified
herein, ORBCOMM [CONFIDENTIAL TREATMENT].

         (c)     Except with respect to the application of Section 18(n)
hereof, the rights of the parties under this Section 15 shall be the exclusive
method of dispute resolution with respect to any claim or controversy regarding
any matter covered by this Agreement.


SECTION 16 - COMPLIANCE WITH LAWS

         Each of the parties shall comply in all material respects with all
applicable laws, rules and regulations of any Governmental Authority in the
performance of its obligations hereunder.  In particular, Licensee agrees to
comply with all applicable laws of the United States regarding export controls,
international traffic in arms regulations and foreign corrupt practices.  In
addition, but not in limitation of the foregoing, summaries of the current
provisions of the United States Federal International Traffic in Arms
Regulations and of the Prohibited Foreign Trade Practices Act are set forth in
Attachment J.


SECTION 17 -FRANCHISE FEES

         In the event Licensee shall receive franchise or any other similar
fees from a In-Country Representative that exceed in total the sum of U.S.
[CONFIDENTIAL TREATMENT] Licensee shall pay to ORBCOMM [CONFIDENTIAL TREATMENT]
of all such fees in excess of such amount.  Such payments shall be made to
ORBCOMM in U.S. dollars within [CONFIDENTIAL TREATMENT] month of [CONFIDENTIAL
TREATMENT].  If the franchise or other similar fee is received by Licensee in a
currency other than U.S. dollars, the amount due to ORBCOMM shall be calculated
using the exchange rate for such currency in effect at Morgan Guaranty Trust
Company of New York at the close of business in New York on the last business
day of the month when the franchise or other similar fee is received by
Licensee.

assigned in whole or in part (by operation of law or otherwise) by Licensee
without the express written consent of ORBCOMM, which consent shall not be
unreasonably withheld.

are hereby made part of this Agreement) contain the entire understanding
between Licensee and ORBCOMM and supersede all prior written and oral
understandings relating to the subject hereof.  No representations, agreements,
modifications or understandings not contained herein shall be valid or

Agreement may be brought within one year of the later of the occurrence of the
event giving rise to the claim and actual knowledge thereof by the party
asserting such claim.

         (ii)  For purposes of Section 18(n), each of the parties by its

agrees not to assert, by way of motion, as a defense or otherwise, in any such
proceeding, any claims that it is not subject personally to the jurisdiction of
the above-named courts, that its property is exempt or immune from attachment
or execution, that any such proceeding brought in one of the above-named courts
is improper, or that this Agreement or the subject matter hereof may not be
enforced in or by such court.  Each of the parties hereby consents to service
of process in any such proceeding in any manner permitted by the laws of the
State of New York and agrees that service of process by international
registered mail, return receipt requested, at the address specified in or
pursuant to Section 18(a) hereof is reasonably calculated to give actual
notice.  Each party agrees that at the other party's request it will appoint an
agent for service of process within the State of New York.

         (e)     Force Majeure.  Neither party shall be held responsible for
failure or delay in performance or delivery if such failure or delay is the
result of an act of God, the public enemy, embargo, governmental act, fire,
accident, war, riot, strikes, inclement weather or other cause of a similar
nature that is beyond the control of the parties.  In the event of such
occurrence, this Agreement shall be amended by mutual agreement to reflect an
extension in the period of performance and/or time of delivery.  Failure to
agree on an equitable extension shall be considered a claim or controversy and
resolved in accordance with Section 15.

         (f)     Waiver.  It is understood and agreed that no failure or delay
by either ORBCOMM or Licensee in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, power or privilege hereunder.  No waiver of any
terms or conditions of this Agreement shall be deemed to be a waiver of any
subsequent breach of any term or condition.  All waivers must be in writing and
signed by the party sought to be bound.

         (g)     Severability.  If any part of this Agreement shall be held
unenforceable, the remainder of this Agreement will nevertheless remain in full
force and effect.

         (h)     Headings.  Headings in this Agreement are included for
convenience of reference

only and shall not constitute a part of this Agreement for any other purpose.

         (i)     Independent Contractors.  Licensee and ORBCOMM are independent
contractors to one another, neither party has the authority to bind the other
in any way or to any third party, and nothing in this Agreement shall be
construed as granting either party the right or authority to act as a
representative, agent, employee or joint venturer of the other.

         (j)     Non-Disclosure.  Each of the parties to this Agreement
acknowledge the execution of the Mutual Non-Disclosure Agreement dated as of

         (k)     English Language; Communication in English.  The parties
recognize and agree that while this Agreement may be translated into other
languages, the English language version of this Agreement shall be the official
version of this Agreement and shall prevail if any dispute in the
interpretation of this Agreement between such languages arises between the
parties.  The parties agree that all communications, notices or any written
material to be provided by ORBCOMM to Licensee or by Licensee to ORBCOMM under
this Agreement shall be in the English language or accompanied by an accurate

ORBCOMM System and the ORBCOMM Services provided pursuant to this Agreement are
unique and recognizes and affirms that in the event of any breach of this
Agreement by it, money damages may not be adequate and the other party may have
no adequate remedy at law.  Accordingly, each of the parties agrees that the
other party shall have the right, in addition to any other rights and remedies
existing in its favor, to enforce its rights and the other party's obligations
hereunder not only by an action or actions for damages but also an action or
actions for specific performance, injunctive relief and/or other equitable

         (a)     Ground Segment Design.  To the fullest extent permitted by
law, the parties to this Contract acknowledge and agree that the hardware and
software that comprise the ORBCOMM Gateway are a collection of custom-developed
hardware and software or customized adaptations of commercially available
hardware and software that have been configured for the ORBCOMM System
messaging application and have been designed to ensure that more than one
licensee can use the ORBCOMM System to provide ORBCOMM Services.  To the
fullest extent permitted by law, the parties further acknowledge and agree that
(i) it is critical that licensee systems not interfere with each other and (ii)
to ensure that mutually compatible operations can take place, it is essential
that Licensee purchase from ORBCOMM, on the terms and conditions set forth
herein, the ORBCOMM Gateway hardware specified herein to be used in the
Territory and that such ORBCOMM Gateway hardware be installed, integrated and
tested by ORBCOMM.

         (b)     Purchase and Sale of ORBCOMM Gateway Hardware and Related
Services. (i) Licensee shall procure and install in the Territory, either
directly or through a wholly owned subsidiary, the ORBCOMM Gateway hardware
described in Attachment 1 to this Contract (the





                                     Page 3
<PAGE>   4
"Ground Segment Hardware"), which ORBCOMM Gateway shall incorporate at least
[CONFIDENTIAL TREATMENT] GESs (the "Initial Purchase").  In connection with the
purchase of the Ground Segment Hardware, Licensee shall procure the related
construction, installation, integration, test and training services necessary
to construct, install and operate the Ground Segment Hardware in the Territory
as more fully described in Attachment 2 to this Contract (the "Related

Licensee and accepted by ORBCOMM on the Effective Date.

         (B)  The parties further agree that the purchase, installation and
acceptance of the Ground Segment Hardware may be delayed if Licensee contracts
with another ORBCOMM System service licensee to share the use of such other
service licensee's ground segment hardware, if in ORBCOMM's sole opinion,
determined from time to time, the use of such other ground segment hardware
will not significantly degrade the quality of service in the Territory or in
the territory of such other licensee or adversely impact the overall operation
or functioning of the ORBCOMM System.  ORBCOMM shall be entitled to perform any
and all tests it deems, in its reasonable opinion, to be necessary or
appropriate to ensure the proper functioning and operation of the shared ground
segment hardware.  Licensee shall immediately notify ORBCOMM of the occurrence
of an event of default or an event that with the giving of notice or lapse of
time, or both, would result in an event of default under such agreement or the
receipt of a notice of termination under such agreement.  If such agreement is
terminated, Licensee shall immediately place an order with ORBCOMM for the
purchase of the necessary Ground Segment Hardware.  A copy of any such
contract, with a certified translation into English, if necessary, shall be
provided to ORBCOMM.

         (c)     Additional Licensee Responsibilities.  Licensee shall:

Segment Hardware, ORBCOMM shall conduct a pre-shipment integration test that
confirms that all elements of the Ground Segment Hardware to be shipped are
properly integrated and work in accordance with the Gateway Product
Specifications.  Such pre-shipment integration test shall be performed at an
integration facility or facilities and at a time specified by ORBCOMM.  ORBCOMM
shall be entitled to perform such testing using a designated test antenna and
associated pedestal, which shall conform to all required specifications
hereunder, in conjunction with all other Licensee-specific Ground Segment
Hardware.  The antenna and pedestal forming the Ground Segment Hardware to be
provided hereunder will be shipped once all unit testing and certification has
been performed and documented for these components.  ORBCOMM shall use all
commercially reasonable efforts to provide Licensee with two weeks notice of
the time and location of such pre-shipment integration test, and Licensee shall
be entitled to witness such test.  On successful completion of the pre-shipment
integration test, ORBCOMM shall provide Licensee with a Pre-Shipment
Integration Test Certificate, the form of which shall be attached as an exhibit
to the Gateway Implementation Plan.

         (b)     Acceptance.  The Ground Segment Hardware shall be accepted in
accordance with the Gateway Acceptance Test or the Supplemental GES Acceptance
Test, as the case may be.  The Gateway Acceptance Test or the Supplemental GES
Acceptance Test, as the case may be, shall take place at the location where the
Ground Segment Hardware is to be installed and used by Licensee.  The Gateway
Acceptance Test or Supplemental GES Acceptance Test, as the case may be, shall
be scheduled at a mutually convenient time within ten days after ORBCOMM
notifies Licensee that installation of Ground Segment Hardware is complete.
Licensee shall satisfy itself during the Gateway Acceptance Test or
Supplemental GES Acceptance Test that the Ground Segment Hardware being
installed conforms to the requirements set forth in such tests. Within seven
days after the Gateway Acceptance Test or Supplemental GES Acceptance Test,
Licensee shall give written notice of any claim, together with supporting
documentation thereof, that any Ground Segment Hardware has failed to pass any
of the tests prescribed in the applicable Gateway Acceptance Test plan or
Supplemental GES Acceptance Test plan..  After successful completion of the
Gateway Acceptance Test or Supplemental GES Acceptance Test, as the case may
be, ORBCOMM and Licensee shall execute a certificate certifying that the Ground
Segment Hardware for which such test was performed successfully passed the
Gateway Acceptance Test (the "Gateway Acceptance Test





                                     Page 7
<PAGE>   8
Certificate") or the Supplemental GES Acceptance Test (the "Supplemental GES
Acceptance Test Certificate"), as the case may be, provided that ORBCOMM and
Licensee may identify non-material deficiencies in the Ground Segment Hardware
that will be placed on a mutually agreed punch list, the completion of which
shall not affect delivery, acceptance, payment or transfer of title for such
Ground Segment Hardware.  If Licensee (i) fails to participate in the Gateway
Acceptance Test or Supplemental GES Acceptance Test, (ii) fails to notify
ORBCOMM as required by this Section 4(b), or (iii) uses the Ground Segment
Hardware for any purposes other than testing in connection with the acceptance
testing process set forth herein, Licensee agrees that it shall be deemed to
have executed the Gateway Acceptance Test Certificate or the Supplemental GES
Acceptance Test Certificate, as the case may be.

         (c)     Transfer of Title.  Title to the Ground Segment Hardware
delivered hereunder shall pass to Licensee on delivery of the Gateway
Acceptance Test Certificate or the Supplemental GES Acceptance Test
Certificate, as the case maybe, and receipt of final payment for such Ground
Segment Hardware.


SECTION 5 - DELIVERY AND RISK OF LOSS

         (a)     Delivery and Risk of Loss.  ORBCOMM shall transport the Ground
Segment Hardware CIP to a major seaport, airport or such other location in the
Territory for delivery as the parties may mutually agree on (the
"Point-of-Entry").  As specified in Sections 2(c)(iii) and (v), Licensee as
importer of the Ground Segment Hardware shall effect customs clearance and pay
all fees, import duties, tariffs and taxes associated therewith.  Any demurrage
arising from customs clearance shall be to the account of Licensee.  Licensee
shall accept delivery of the Ground Segment Hardware on unloading, before it
clears customs, at the Point-of-Entry. Licensee shall arrange and be
responsible for the transport of the Ground Segment Hardware from the
Point-of-Entry to the installation site(s).  Risk of loss for the Ground
Segment Hardware shall pass to Licensee when the Ground Segment Hardware is
unloaded, before it clears customs.  Thereafter, Licensee shall insure at its
expense the Ground Segment Hardware, and on written request shall provide
ORBCOMM with evidence of such insurance.

         (b)     Schedule for Delivery.  The schedule for delivery of the
Ground Segment Hardware by ORBCOMM shall be established in the Gateway
Implementation Plan, provided that the ORBCOMM Gateway incorporating
[CONFIDENTIAL TREATMENT] GES shall be installed in the Territory and accepted
as soon as possible.  Both parties hereto acknowledge and agree that the
schedule for installation of the Ground Segment Hardware shall be an "all
commercially reasonable efforts" schedule only, and that ORBCOMM shall not be
held liable for damages caused by changes or delays to the schedule.

         (c)     Liens.  So long as there remains any unpaid amount by Licensee
to ORBCOMM hereunder, Licensee shall not permit, allow or suffer the attachment
of any lien, charge or encumbrance of any kind on any of the Ground Segment
Hardware and Licensee shall pay when due any assessments, levies, fees, taxes,
duties or other charges against the Ground Segment Hardware.

SECTION 6 - GROUND SEGMENT HARDWARE WARRANTY

         (a)     Warranty.  (i)  Notwithstanding delivery and acceptance by
Licensee of the Ground Segment Hardware as provided in Sections 4 and 5 and
subject to the warranty conditions in this Section 6, ORBCOMM hereby warrants
that, for a period of [CONFIDENTIAL TREATMENT] months after the earlier of (A)
completion of the Gateway Acceptance Test or Supplemental Gateway Acceptance
Test, as the case may be, and (B) [CONFIDENTIAL TREATMENT] months from the
arrival of the applicable Ground Segment Hardware at the Point-of-Entry, which
nine-month period shall be extended day-for-day until ORBCOMM has completed

Segment Hardware, free from damage, at the installation site (the "Warranty
Period"), the Ground Segment Hardware shall be free from defects in material
and workmanship and shall operate and conform in all material respects with the
performance capabilities, specifications, functions and other descriptions set
forth in the Gateway Product Specifications.  ORBCOMM shall, at its expense,
repair or replace any Ground Segment Hardware that does not conform to such
warranty.  ORBCOMM's obligation during the Warranty Period shall be limited to
repair or replacement of any Ground Segment Hardware for which it has provided
a warranty hereunder. Notice of all claimed defects must be provided in writing
to ORBCOMM within the Warranty Period.  ORBCOMM shall determine to its
satisfaction after inspection that the product or part was defective.  Any
Ground Segment Hardware repaired or replaced shall be subject only to the
original Warranty Period.  The warranty set forth herein is Licensee's
exclusive remedy against ORBCOMM for any defective Ground Segment Hardware.

         (ii)         The warranty set forth herein shall not extend to any
portion of the Ground Segment Hardware that, upon ORBCOMM's or its
subcontractors' examination is found to have been (A) mishandled, misused or
subject to negligence, accident or abuse by Licensee or its officers,
employees, contractors, representatives, agents or consultants (other than
ORBCOMM), (B) operated or maintained contrary to ORBCOMM's specifications or
instructions or otherwise used improperly, (C) tampered with or damaged as
evidenced by, for example, broken seals, unauthorized modifications, damaged
packaging containers and the like, (D) repaired and/or altered by anyone other
than ORBCOMM or its subcontractors without ORBCOMM's prior written approval,
which approval shall not be unreasonably withheld or (E) delivered to ORBCOMM
not in conformance in all material respects with the notice requirements set
forth herein.

         (b)          Place of Repair.  During the Warranty Period, ORBCOMM
shall have the option to repair the defective goods on-site or, if feasible,
require that the goods be returned to its or its designee's facilities;
provided that all shipping and insurance costs associated with shipment of
defective goods to ORBCOMM's designated repair facility shall be paid by
Licensee and all shipping and insurance costs associated with return shipment
of repaired goods shall be paid by ORBCOMM; and provided further, that items
found not to be defective shall be returned at Licensee's expense.

         (c)          Disclaimer of Warranties.  EXCEPT AS OTHERWISE PROVIDED
IN THIS SECTION 6, TO THE FULLEST EXTENT PERMITTED BY LAW, ORBCOMM SHALL





                                     Page 9
<PAGE>   10
NOT BE DEEMED TO HAVE MADE ANY REPRESENTATIONS OR WARRANTIES WHATSOEVER WITH
RESPECT TO THE GROUND SEGMENT HARDWARE, THE RELATED SERVICES OR THE OTHER
SERVICES TO BE PROVIDED UNDER THIS CONTRACT.  TO THE FULLEST EXTENT PERMITTED
BY LAW, ORBCOMM EXPRESSLY DISCLAIMS, AND LICENSEE HEREBY EXPRESSLY WAIVES,
RELEASES AND RENOUNCES ALL OTHER WARRANTIES, OBLIGATIONS AND LIABILITIES OF
ORBCOMM, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO,
INCLUDING, BUT NOT LIMITED TO, (i) ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE; (ii) ANY IMPLIED WARRANTY ARISING FROM COURSE

SUITABILITY FOR USE, THAT IS NOT CONTAINED IN THIS CONTRACT SHALL BE DEEMED TO
BE A WARRANTY BY ORBCOMM.

         (d)          Limitation of Liabilities.  (i)  NOTWITHSTANDING ANYTHING
CONTAINED HEREIN TO THE CONTRARY, IN NO EVENT SHALL EITHER PARTY HAVE ANY
OBLIGATION, LIABILITY, RIGHT, CLAIM OR REMEDY TO THE OTHER UNDER THIS CONTRACT
FOR LOSS OF USE, REVENUE OR PROFIT OR FOR ANY OTHER INDIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES.

         (ii)         In addition, in no event shall ORBCOMM or any of the
other ORBCOMM Entities have any liability under or resulting from this
Agreement and any other Transaction Agreement:

                      (A) until the cumulative aggregate amount of any claims,
         losses costs, expenses, damages or liabilities incurred by Licensee
         for which ORBCOMM would be responsible to Licensee under or as a
         result of this Agreement or any other Transaction Agreement exceeds
         [CONFIDENTIAL TREATMENT] and then only to the extent of such excess;
         and

SECTION 8 - OTHER SERVICES

         Upon the written request of Licensee, ORBCOMM shall provide to
Licensee the following additional services (collectively, the "Other

         Services, ORBCOMM shall invoice Licensee for the full cost of the
         Other Services performed.  All amounts set forth on such invoices
         shall be paid to ORBCOMM by Licensee within [CONFIDENTIAL TREATMENT]
         days of the receipt by Licensee of such invoice.

terminated by Licensee at any time after the occurrence of any of the following
events of default:

                      (i)           ORBCOMM shall fail to observe or perform
         any of its obligations under this Contract, and such failure shall
         remain uncured for a period of [CONFIDENTIAL TREATMENT] days after

                      (ii)          Licensee shall have terminated the Service
         License Agreement pursuant to Section 9(b)(i) thereof.

         (b)          Licensee Events of Default.  This Contract may be
terminated by ORBCOMM at any time after the occurrence of any of the following

                      (i)           Licensee shall fail to pay any amount due
         under this Contract within [CONFIDENTIAL TREATMENT] days after receipt
         of notice from ORBCOMM that such amount is due;

                      (ii)          Licensee shall fail to observe or perform
         any of its obligations under this Contract (other than breaches
         specified in Sections 8(b)(i)), and such failure shall remain uncured
         for a period of [CONFIDENTIAL TREATMENT] days after receipt by
         Licensee of written notice thereof; or

                      (iii)         ORBCOMM shall have terminated the Service
         License Agreement pursuant to Section 9(b)(ii) thereof.

         (c)          Remedies On Termination. Subject to Sections 6(c) and
6(d), termination of this Contract by the party not in default in accordance
with the terms hereof shall be without prejudice to any other rights or
remedies such party shall have by law.

         (d)          Obligations After Termination.  The obligations set forth
in Sections 6(c), 6(d), 10, 11(e), 11(k), 11(l) and 11(o) and those obligations
that relate to any amounts due and owing for any periods prior to termination
or expiration of this Contract shall survive such termination or expiration.


SECTION 10 - DISPUTE RESOLUTION

         (a)          Subject to the provisions of Section 11(o), in the event
of a claim or controversy regarding any matter covered by this Contract,
ORBCOMM and Licensee shall use all reasonable efforts to resolve such claim or
controversy within 60 calendar days of receipt by either party of notice of the
existence of any such claim or controversy.  In the event the parties are
unable to agree on the resolution of such claim or controversy within such
period of time, either party may remove the claim or controversy for settlement
by final and binding arbitration in New York, NY, in accordance with the then
existing United States domestic rules





                                    Page 12
<PAGE>   13
of the American Arbitration Association ("AAA") (to the extent not modified by
this Section). In the event that more than one claim or controversy arises
under this Contract, such disputes may be consolidated in a single arbitral
proceeding.  The arbitral tribunal shall be composed of three arbitrators.
Each of ORBCOMM and Licensee shall appoint one arbitrator. If any party shall
fail to appoint an arbitrator within 30 days from the date on which the other
party's request for arbitration has been communicated to the first party, such
appointment shall be made by the AAA. The two arbitrators so appointed shall
agree upon the third arbitrator who shall act as chairman of the arbitral
tribunal and who have significant operational expertise in geographically
distributed data communications networks.  If the two appointed arbitrators
fail to nominate a chairman within ten days from the date as of which both
arbitrators shall have been appointed, such chairman shall be selected by the
AAA.  In all cases, the arbitrators shall be fluent in English.  Judgment upon
any award rendered by the arbitrators may be entered in any court having
jurisdiction or application may be made for judicial acceptance of the award
and an order of enforcement, as the case may be.  The parties agree that if it
becomes necessary for any party to enforce an arbitral award by a legal action
or additional arbitration or judicial methods, the party against whom
enforcement is sought shall pay all reasonable costs and attorney's fees
incurred by the party seeking to enforce the award.

         (b)          Pending a final determination by the arbitrators, if the
claim or controversy concerns the payment by Licensee of any fees or amounts
due hereunder (including the right to conduct an audit of such fees or
amounts), ORBCOMM shall have the right to terminate Licensee's access to the
ORBCOMM System and, in the event ORBCOMM elects to exercise such right and
notwithstanding any determination by the arbitrators, Licensee's sole remedy
for such termination by ORBCOMM shall be an extension of the term of this
Contract equal to the period during which Licensee was denied access to the
ORBCOMM System.

         (c)          Except with respect to the application of Section 11(o)
hereof, the rights of the parties under this Section 10 shall be the exclusive
remedy with respect to any claim or controversy regarding any matter covered by
this Contract.


SECTION 11 - MISCELLANEOUS

         (a)          Compliance With Laws.  Each of the parties shall comply
in all material respects with all applicable laws, rules and regulations of any
applicable Governmental Authority in the performance of its obligations
hereunder.  In particular, Licensee agrees to comply with all applicable laws
of the United States regarding export controls, international traffic in arms
regulations and foreign corrupt practices.  In addition, but not in limitation
of the foregoing, summaries of the current provisions of the United States
Federal International Traffic in Arms Regulations and of the Prohibited Foreign
Trade Practices Act are set forth in Attachment 4.

or to such other persons or addresses as either party may designate by written
notice to the other. All such notices sent to either Licensee or ORBCOMM shall
be effective the earlier of (i) ten business days after the date of mailing by
sender, or (ii) the date of actual receipt.

         (c)          Successors and Assigns.  This Contract shall be binding
upon the parties, their successors and permitted assigns.  Subject to Section
10 of the Service License Agreement, neither this Contract nor any interests or
duties of Licensee hereunder may be assigned in whole or in part (by operation
of law or otherwise) by Licensee without the express written consent of
ORBCOMM, which consent shall not be unreasonably withheld.

         (d)          Entire Agreement.  This Contract and all attachments
(which are hereby made part of this Contract) contain the entire understanding
between Licensee and ORBCOMM and supersede all prior written and oral
understandings relating to the subject hereof.  No representations, agreements,
modifications or understandings not contained herein shall be valid or
effective unless agreed to in writing and signed by both parties.  Any
modification or amendment of this Contract must be in writing and signed by
both parties.

         (e)          Governing Law and Jurisdiction.  (i)  The construction,
interpretation and performance of this Contract, as well as the legal relations
of the parties arising hereunder,





                                    Page 14
<PAGE>   15
shall be governed by and construed in accordance with the laws of the State of
New York, without giving effect to the conflict or choice of law provisions
thereof.  The United Nations Convention on Contracts for the International Sale
of Goods (1980) shall not apply to any provisions of this Contract.  Neither
party may bring any action for a claim under this Contract later than one year
after the termination of this Contract; provided that claims under any
provision of this Contract that survives termination of this Contract may be
brought within one year of the later of the occurrence of the event giving rise
to the claim and actual knowledge thereof by the party asserting such claim.

         (ii)  For purposes of Section 11(o), Licensee by its execution hereof
(A) hereby irrevocably submits to the nonexclusive jurisdiction of the state
courts of the State of New York and to the nonexclusive jurisdiction of the
United States District Court for the Southern District of New York, for the
purpose of any suit, action or other proceeding arising out of or based upon
this Contract or the subject matter hereof brought by ORBCOMM and (B) hereby
waives to the extent not prohibited by law, and agrees not to assert, by way of
motion, as a defense or otherwise, in any such proceeding, any claims that it
is not subject personally to the jurisdiction of the above-named courts, that
its property is exempt or immune from attachment or execution, that any such
proceeding brought in one of the above-named courts is improper, or that this
Contract or the subject matter hereof may not be enforced in or by such court.
Licensee hereby consents to service of process in any such proceeding in any
manner permitted by the laws of the State of New York and agrees that service
of process by international registered mail, return receipt requested, at the
address specified in or pursuant to Section 11(b) hereof is reasonably
calculated to give actual notice.  Licensee agrees that at ORBCOMM's request it
will appoint an agent for service of process within the State of New York.

         (f)          Force Majeure.  Neither party shall be held responsible
for failure or delay in performance or delivery if such failure or delay is the
result of an act of God, the public enemy, embargo, governmental act, fire,
accident, war, riot, strikes, inclement weather or other cause of a similar
nature that is beyond the control of the parties.  In the event of such
occurrence, this Contract shall be amended by mutual agreement to reflect an
extension in the period of performance and/or time of delivery.  Failure to
agree on an equitable extension shall be considered a claim or controversy and
resolved in accordance with Section 10.

         (g)          Waiver.  It is understood and agreed that no failure or
delay by either ORBCOMM or Licensee in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, power or privilege hereunder.  No waiver of any
terms or conditions of this Contract shall be deemed to be a waiver of any
subsequent breach of any term or condition.  All waivers must be in writing and
signed by the party sought to be bound.

         (h)          Severability.  If any part of this Contract shall be held
unenforceable, the remainder of this Contract will nevertheless remain in full
force and effect.

         (i)          Headings.  Headings in this Contract are included for
convenience of reference only and shall not constitute a part of this Contract
for any other purpose.

         (a)     Warranty.  (i)  Notwithstanding delivery and acceptance by
Licensee of the Ground Segment Hardware as provided in Sections 4 and 5 and
subject to the warranty conditions in this Section 6, ORBCOMM hereby warrants
that, for a period of [CONFIDENTIAL TREATMENT] months after the successful
completion of the Gateway Acceptance Test or the Supplemental Gateway
Acceptance Test, as the case may be, provided that such [CONFIDENTIAL
TREATMENT] months shall be reduced day-for-day for each day any portion of the
Ground Segment Hardware remains in customs at the Point-of-Entry in excess of
[CONFIDENTIAL TREATMENT] calendar days (so long as such customs delay is not
the result of the failure of ORBCOMM to provide the necessary customs shipment
documentation) and for each day where Licensee has failed to perform its
obligations hereunder (the "Warranty Period"), the Ground Segment Hardware
shall be free from defects in material and workmanship and shall operate and
conform in all material respects with the performance capabilities,
specifications, functions and other descriptions set forth in the Gateway
Product Specifications.  ORBCOMM shall, at its expense, repair or replace any
Ground Segment Hardware that does not conform to such warranty.  ORBCOMM's
obligation during the Warranty Period shall be limited to repair or replacement
of any Ground Segment Hardware for which it has provided a warranty hereunder.
Notice of all claimed defects must be provided in writing to ORBCOMM within the
Warranty Period.  ORBCOMM shall determine after inspection that the product or
part was defective and if ORBCOMM determines that such product or part was not
defective, ORBCOMM shall provide Licensee with prompt written notice of such
determination.  Any Ground Segment Hardware repaired or replaced shall be
subject only to the original Warranty Period, [CONFIDENTIAL TREATMENT].  The
warranty set forth herein is Licensee's exclusive remedy against ORBCOMM for
any defective Ground Segment Hardware.

         (ii)    The warranty set forth herein shall not extend to any portion
of the Ground Segment Hardware that, upon ORBCOMM's or its subcontractors'
examination is found to have been (A) mishandled, misused or subject to
negligence, accident or abuse by Licensee or its officers, employees,
contractors, representatives, agents or consultants (other than ORBCOMM), (B)
operated or maintained contrary to ORBCOMM's specifications or instructions or
otherwise





                                      -11-
<PAGE>   12
used improperly, (C) tampered with or damaged as evidenced by, for example,
broken seals, unauthorized modifications, damaged packaging containers and the
like, (D) repaired and/or altered by anyone other than ORBCOMM or its
subcontractors without ORBCOMM's prior written approval, which approval shall
not be unreasonably withheld or (E) delivered to ORBCOMM not in conformance in
all material respects with the notice requirements set forth herein.

         (b)     Place of Repair.  During the Warranty Period, ORBCOMM shall
have the option to repair the defective goods on-site or, if feasible, require
that the goods be returned to its or its designee's facilities, provided that
all shipping and insurance costs associated with shipment of defective goods to
ORBCOMM's designated repair facility shall be paid by Licensee and all shipping
and insurance costs associated with return shipment of repaired goods shall be
paid by ORBCOMM; and provided further, that items found not to be defective
shall be returned at Licensee's expense.

         (c)     Disclaimer of Warranties.  EXCEPT AS OTHERWISE SPECIFICALLY
PROVIDED IN THIS CONTRACT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
ORBCOMM SHALL NOT BE DEEMED TO HAVE MADE ANY REPRESENTATIONS OR WARRANTIES
WHATSOEVER WITH RESPECT TO THE GROUND SEGMENT HARDWARE, THE RELATED SERVICES OR
THE OTHER SERVICES TO BE PROVIDED UNDER THIS CONTRACT.  EXCEPT AS OTHERWISE
SPECIFICALLY PROVIDED IN THIS CONTRACT, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ORBCOMM EXPRESSLY DISCLAIMS, AND LICENSEE HEREBY EXPRESSLY
WAIVES, RELEASES AND RENOUNCES ALL OTHER WARRANTIES OF ORBCOMM, EXPRESS OR
IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO, INCLUDING, BUT NOT
LIMITED TO, (i) ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE; (ii) ANY IMPLIED WARRANTY ARISING FROM COURSE OF
PERFORMANCE, COURSE OF DEALING OR USAGE OF TRADE; (iii) ANY WARRANTIES AS TO
THE ACCURACY, AVAILABILITY OR CONTENT OF THE GROUND SEGMENT HARDWARE, THE
RELATED SERVICES OR THE OTHER SERVICES PROVIDED BY OR THROUGH ORBCOMM UNDER
THIS CONTRACT; AND (iv) ANY WARRANTY UNDER ANY THEORY OF LAW, INCLUDING ANY
TORT, NEGLIGENCE, STRICT LIABILITY, CONTRACT OR OTHER LEGAL OR EQUITABLE
THEORY.  NO REPRESENTATION OR OTHER AFFIRMATION OF FACT, INCLUDING, BUT NOT
LIMITED TO, STATEMENTS REGARDING CAPACITY OR SUITABILITY FOR USE, THAT IS NOT
CONTAINED IN THIS CONTRACT SHALL BE DEEMED TO BE A WARRANTY BY ORBCOMM.

         (d)     Limitation of Liabilities.  NOTWITHSTANDING ANYTHING CONTAINED
HEREIN TO THE CONTRARY, IN NO EVENT SHALL EITHER PARTY HAVE ANY OBLIGATION,
LIABILITY, RIGHT, CLAIM OR REMEDY TO THE OTHER UNDER THIS CONTRACT FOR LOSS OF
USE, REVENUE OR PROFIT OR FOR ANY OTHER INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES.  In addition, in no event shall any liability





                                      -12-

of ORBCOMM exceed an amount equal to [CONFIDENTIAL TREATMENT].


SECTION 7 - GROUND SEGMENT HARDWARE CHANGES

         ORBCOMM reserves the right to change on terms that are commercially
reasonable and only to the extent necessary, any of the terms, conditions and
provisions of Sections 2, 3, 4, 5 or 6 that ORBCOMM deems are reasonably
necessary if any applicable law in the Territory requires that (a) ORBCOMM
change the design of the Ground Segment Hardware or (b) any elements of the
Ground Segment Hardware be procured in the Territory.

         parties prior to the dispatch of the ORBCOMM personnel.

                 (ii)     For each On-Site Technical Assistance Service,
         Licensee agrees to pay to ORBCOMM U.S. [CONFIDENTIAL TREATMENT] per

         telephonic technical and operational advice concerning the Licensee

         pursuant to the ORBCOMM Gateway Software License Agreement.  Such
         advice shall be provided by a qualified engineer or technician and
         shall only be available between the hours of 9:00 a.m.  and 5:00 p.m.

         ORBCOMM shall invoice Licensee for the full cost of the Other Services
         performed.  All amounts set forth on such invoices shall be paid to
         ORBCOMM by Licensee within [CONFIDENTIAL TREATMENT] days of the
         receipt by Licensee of such invoice.

                 (i)      ORBCOMM shall fail to observe or perform any of its
         obligations under this Contract, and, except as provided in Section
         5(b)(vi) or Section 9(a)(ii), such failure shall remain uncured for a
         period of [CONFIDENTIAL TREATMENT] days after receipt by ORBCOMM of
         written notice thereof;

                 (ii)     ORBCOMM shall fail to observe or perform any of its
         obligations under Section 6(a) and with respect to the repair or

         ORBCOMM of written notice thereof and in the case of the repair or
         replacement of any other portion of the ORBCOMM Gateway, such failure
         shall remain uncured for a period of [CONFIDENTIAL TREATMENT] days
         after receipt by ORBCOMM of written notice thereof; or

                 (iii)    Licensee shall have terminated the Service License
         Agreement pursuant to Section 9(b)(i) or 9(b)(iii) thereof.

         (b)     Licensee Events of Default.  This Contract may be terminated
by ORBCOMM at any time after the occurrence of any of the following events of
default:

                 (i)      Licensee shall fail to pay any amount due under this
         Contract within [CONFIDENTIAL TREATMENT] days after receipt of notice
         from ORBCOMM that such amount is due;

                 (ii)     Licensee shall fail to observe or perform any of its
         obligations under this





                                      -14-
<PAGE>   15
         Contract (other than breaches specified in Sections 9(b)(i)), and such
         failure shall remain uncured for a period of [CONFIDENTIAL TREATMENT]
         days after receipt by Licensee of written notice thereof; or

                 (iii)    ORBCOMM shall have terminated the Service License
         Agreement pursuant to Section 9(b)(ii) thereof.

         (c)     Remedies On Termination. Subject to Sections 6(c) and 6(d),
termination of this Contract by the party not in default in accordance with the
terms hereof shall be without prejudice to any other rights or remedies such
party shall have by law.

         (d)     Obligations After Termination.  The obligations set forth in
Sections 6(c), 6(d), 10, 11(e), 11(k), 11(l) and 11(o) and those obligations
that relate to any amounts due and owing for any periods prior to termination
or expiration of this Contract shall survive such termination or expiration.


SECTION 10 - DISPUTE RESOLUTION

         (a)     Subject to the provisions of Section 11(o), in the event of a
claim or controversy regarding any matter covered by this Contract, ORBCOMM and
Licensee shall use all reasonable efforts to resolve such claim or controversy
within 60 calendar days of receipt by either party of notice of the existence
of any such claim or controversy.  In the event the parties are unable to agree
on the resolution of such claim or controversy within such period of time,
either party may remove the claim or controversy for settlement by final and
binding arbitration in New York, NY, in accordance with the then existing
United States domestic rules of the American Arbitration Association ("AAA")
(to the extent not modified by this Section).  In the event that more than one
claim or controversy arises under this Contract, such disputes may be
consolidated in a single arbitral proceeding.  The arbitral tribunal shall be
composed of three arbitrators.  Each of ORBCOMM and Licensee shall appoint one
arbitrator. If any party shall fail to appoint an arbitrator within 30 days
from the date on which the other party's request for arbitration has been
communicated to the first party, such appointment shall be made by the AAA. The
two arbitrators so appointed shall agree upon the third arbitrator who shall
act as chairman of the arbitral tribunal and who have significant operational
expertise in geographically distributed data communications networks.  If the
two appointed arbitrators fail to nominate a chairman within ten days from the
date as of which both arbitrators shall have been appointed, such chairman
shall be selected by the AAA.  In all cases, the arbitrators shall be fluent in
English.  Judgment upon any award rendered by the arbitrators may be entered in
any court having jurisdiction or application may be made for judicial
acceptance of the award and an order of enforcement, as the case may be.  The
parties agree that if it becomes necessary for any party to enforce an arbitral
award by a legal action or additional arbitration or judicial methods, the
party against whom enforcement is sought shall pay all reasonable costs and
attorney's fees incurred by the party seeking to enforce the award.

<PAGE>   16
         (b)     Pending a final determination by the arbitrators, if the claim
or controversy concerns the payment by Licensee of any fees or amounts due
hereunder (including the right to conduct an audit of such fees or amounts),
ORBCOMM shall have the right to terminate Licensee's access to the ORBCOMM
System unless Licensee posts a bond from a reputable bonding company covering
in full the amount of the disputed payment  In the event ORBCOMM elects to
exercise such right and notwithstanding any determination by the arbitrators,
Licensee's sole remedies for such termination by ORBCOMM shall be an extension
of the term of this Contract equal to the period during which Licensee was
denied access to the ORBCOMM System and in the event the arbitrators determine
that Licensee did not owe ORBCOMM any fees or amounts and Licensee posted a
bond as specified herein, ORBCOMM shall be obligated to [CONFIDENTIAL
TREATMENT].

         (c)     Except with respect to the application of Section 11(o)
hereof, the rights of the parties under this Section 10 shall be the exclusive
remedy with respect to any claim or controversy regarding any matter covered by
this Contract.


SECTION 11 - MISCELLANEOUS

         (a)     Compliance With Laws.  Each of the parties shall comply in all
material respects with all applicable laws, rules and regulations of any

notice to the other. All such notices sent to either Licensee or ORBCOMM shall
be effective the earlier of (i) ten business days after the date of mailing by
sender, or (ii) the date of actual receipt.

         (c)     Successors and Assigns.  This Contract shall be binding upon
the parties, their successors and permitted assigns.  Subject to Section 10 of
the Service License Agreement, neither this Contract nor any interests or
duties of Licensee hereunder may be assigned in whole or in part (by operation
of law or otherwise) by Licensee without the express written consent of
ORBCOMM, which consent shall not be unreasonably withheld.

         (d)     Entire Agreement.  This Contract and all attachments (which
are hereby made part of this Contract), the Service License Agreement and the
ORBCOMM Gateway Software License Agreement contain the entire understanding
between Licensee and ORBCOMM and supersede all prior written and oral
understandings relating to the subject hereof.  No representations, agreements,
modifications or understandings not contained herein shall be valid or
effective unless agreed to in writing and signed by both parties.  Any
modification or amendment of this Contract must be in writing and signed by
both parties.

         (e)     Governing Law and Jurisdiction.  (i)  The construction,
interpretation and performance of this Contract, as well as the legal relations
of the parties arising hereunder, shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to the
conflict or choice of law provisions thereof.  The United Nations Convention on
Contracts for the International Sale of Goods (1980) shall not apply to any
provisions of this Contract.  Neither party may bring any action for a claim
under this Contract later than one year after the termination of this Contract;
provided that claims under any provision of this Contract that survives
termination of this Contract may be brought within one year of the later of the
occurrence of the event giving rise to the claim and actual knowledge thereof
by the party





                                      -17-

asserting such claim.

         (ii)  For purposes of Section 11(o), Licensee by its execution hereof
(A) hereby irrevocably submits to the nonexclusive jurisdiction of the state
courts of the State of New York and to the nonexclusive jurisdiction of the
United States District Court for the Southern District of New York, for the
purpose of any suit, action or other proceeding arising out of or based upon
this Contract or the subject matter hereof brought by ORBCOMM and (B) hereby
waives to the extent not prohibited by law, and agrees not to assert, by way of
motion, as a defense or otherwise, in any such proceeding, any claims that it
is not subject personally to the jurisdiction of the above-named courts, that
its property is exempt or immune from attachment or execution, that any such
proceeding brought in one of the above-named courts is improper, or that this
Contract or the subject matter hereof may not be enforced in or by such court.
Licensee hereby consents to service of process in any such proceeding in any
manner permitted by the laws of the State of New York and agrees that service
of process by international registered mail, return receipt requested, at the
address specified in or pursuant to Section 11(b) hereof is reasonably
calculated to give actual notice.  Licensee agrees that at ORBCOMM's request it
will appoint an agent for service of process within the State of New York.

         (f)     Force Majeure.  Neither party shall be held responsible for
failure or delay in performance or delivery if such failure or delay is the
result of an act of God, the public enemy, embargo, governmental act, fire,
accident, war, riot, strikes, inclement weather or other cause of a similar
nature that is beyond the control of the parties.  In the event of such
occurrence, this Contract shall be amended by mutual agreement to reflect an
extension in the period of performance and/or time of delivery.  Failure to
agree on an equitable extension shall be considered a claim or controversy and
resolved in accordance with Section 10.

         (g)     Waiver.  It is understood and agreed that no failure or delay
by either ORBCOMM or Licensee in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, power or privilege hereunder.  No waiver of any
terms or conditions of this Contract shall be deemed to be a waiver of any
subsequent breach of any term or condition.  All waivers must be in writing and
signed by the party sought to be bound.

         (h)     Severability.  If any part of this Contract shall be held
unenforceable, the remainder of this Contract will nevertheless remain in full
force and effect.

         (i)     Headings.  Headings in this Contract are included for
convenience of reference only and shall not constitute a part of this Contract
for any other purpose.

         (j)     Independent Contractors.  Licensee and ORBCOMM are independent
contractors to one another, neither party has the authority to bind the other
in any way or to any third party, and nothing in this Contract shall be
construed as granting either party the right or authority to act as a
representative, agent, employee or joint venturer of the other.

         (k)     Non-Disclosure.  Each of the parties to this Contract

October 15, 1996 and each agrees to observe the provisions thereof.

         (l)     English Language; Communication in English.  The parties
recognize and agree that while this Contract may be translated into other
languages, the English language version of this Contract shall be the official
version of this Contract and shall prevail if any dispute in the interpretation
of this Contract between such languages arises between the parties.  The
parties agree that all communications, notices or any written material to be
provided by ORBCOMM to Licensee or by Licensee to ORBCOMM under this Contract
shall be in the English language or accompanied by an accurate and complete
translation into English.

         (m)     Calendar.  The Gregorian calendar shall be used in
calculating, invoicing and paying all amounts due under this Contract.

         (n)     Payments.  All payments due and payable to ORBCOMM hereunder
shall be paid in U.S. Dollars in immediately available funds to the bank
account specified by ORBCOMM in writing.  In the event there is a material
adverse change in the financial conditions or results of operations of
Licensee, ORBCOMM shall have the right to require Licensee to make a cash
deposit or to provide ORBCOMM with an irrevocable letter of credit in favor of
ORBCOMM issued by a bank reasonable acceptable to ORBCOMM, provided that the
amount of such case deposit or irrevocable letter of credit shall bear a
reasonable relationship to amounts generally due and owing under this Contract.

         (o)     Equitable Relief.  Each of the parties acknowledges that the
goods and services provided pursuant to this Contract are unique and recognizes
and affirms that in the event of any breach of this Contract by it, money
damages may not be adequate and the other party may have no adequate remedy at
law.  Accordingly, each of the parties agrees that the other party shall have
the right, in addition to any other rights and remedies existing in its favor,
to enforce its rights and the other party's obligations hereunder not only by
an action or actions for damages but also an action or actions for specific
performance, injunctive relief and/or other equitable relief.
