   7
         as possible with Licensee's normal business operations, and (C) may

         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

         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

         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

         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
   10
         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
   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
   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
   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





                                    Page 13
   14
                 (iii)          If an order for both an Initial Purchase and an
         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.

         (d)     Payment Terms.

                 (i)            For the Initial Purchase, Licensee shall pay
         ORBCOMM (A) the sum of [CONFIDENTIAL TREATMENT] on [CONFIDENTIAL
         TREATMENT], (B) [CONFIDENTIAL TREATMENT] percent of the applicable
         price specified in Section 4(c) less [CONFIDENTIAL TREATMENT], (C)
         [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].

                 (ii)           For all subsequent purchases, Licensee shall
         pay ORBCOMM (i) [CONFIDENTIAL TREATMENT] percent of the applicable
         price specified in Section 4(c) [CONFIDENTIAL TREATMENT], (ii)
         [CONFIDENTIAL TREATMENT] percent upon receipt by Licensee of a
         [CONFIDENTIAL TREATMENT] and (iii) [CONFIDENTIAL TREATMENT] percent
         [CONFIDENTIAL TREATMENT]; provided, 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.

         (e)     Delivery and Acceptance.  ORBCOMM shall transport the Ground
Segment Hardware to a major seaport or airport or such other location in the
Territory for delivery as the parties may mutually agree on (the
"Point-of-Entry").  The Licensee shall accept delivery of the Ground Segment
Hardware, and title to the Ground Segment Hardware delivered shall be deemed to
have passed upon unloading, at the Point-of-Entry.  Licensee shall arrange for





                                    Page 14
   15
the import of the Ground Segment Hardware into the Territory and its
transportation to the installation sites. Licensee shall be responsible for
insuring, at its option and cost, the Ground Segment Hardware from and after
the time it receives title to the Ground Segment Hardware.

         (f)     Schedule.  The schedule for delivery of the Ground Segment
Hardware and for its installation and acceptance testing by ORBCOMM shall be
established by ORBCOMM at the time the order is placed.  Both parties hereto
acknowledge and agree that this will be a "best efforts" schedule only, and
that ORBCOMM shall not be held liable for damages caused by changes or delays
to this schedule.

         (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.

SECTION 5 - OTHER SERVICES

Upon the written request of Licensee, ORBCOMM shall provide to Licensee Repeat
System Acceptance Services and On-Site Technical Assistance Services
(collectively, the "Other Services") described below:

         (a)     Repeat System Acceptance Services.  Repeat System Acceptance
Services consist of providing ORBCOMM personnel or subcontractors at the
Licensee's facilities, after these facilities have been installed and tested,
to perform all tests necessary to ascertain that the Licensee System is still
meeting the requirements of the Acceptance Specifications.  If minor
adjustments to the Licensee System are required to meet the acceptance criteria
described in the Acceptance Specifications, ORBCOMM shall cause such
adjustments to be made, provided that ORBCOMM shall not be required to make,
pursuant to this Section 5, repairs or modifications to the Licensee System
that it deems to be major repairs or modifications.

         (b)     On-Site Technical Assistance Services.  On-Site Technical
Assistance Services consist of sending ORBCOMM personnel or subcontractors to
the Licensee's facilities to provide advice, assistance, training, retraining,
etc. to the Licensee's employees and customers. The number and technical

   18
         (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) the sum of (x)
the number of Subscriber Communicators registered on the Licensee System at any
time during such month multiplied by [CONFIDENTIAL TREATMENT] (the "Subscriber
Base Rate") and (y) the number of kbytes of data using such Subscriber
Communicators relayed through the Licensee's NCC (excluding bytes added to the
Subscriber's message by the ORBCOMM System) multiplied by US$[CONFIDENTIAL

         whether these amounts are collected or not;

                        (B)       include all revenue derived from the
         provision by Licensee, either directly or indirectly, of the ORBCOMM

         System including all revenue derived as a Servicing Licensee;

                        (D)       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; and

                        (E)       exclude the purchase price paid for
         Subscriber Communicators.

         (iii)          ORBCOMM may, in its sole discretion, change the Revenue
Dependent Fee Percentage, the Subscriber Base Rate and/or the Data Throughput
Rate; 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] period, provided that a change in any
[CONFIDENTIAL TREATMENT] of the Revenue Dependent Fee Percentage, Subscriber

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.

                        (y)       with respect to the Subscriber Base Rate,
         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 Subscriber Base





                                    Page 18
   19
         Rate shall not be more than [CONFIDENTIAL TREATMENT] per month per
         Subscriber Communicator.

                        (z)       with respect to the Data Throughput Rate,
         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 Rate 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 the Licensee invoices its
customers, the aggregate number of Subscriber Communicators registered on the
Licensee System at any time during such month and the number of kbytes of data
using such Subscriber Communicators relayed through the Licensee's NCC
(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
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
Satellite Usage Fees remaining unpaid after such [CONFIDENTIAL TREATMENT]
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.

         (iii)          If payments due under this Section 8 cannot be made as
provided herein due to [CONFIDENTIAL TREATMENT] or other [CONFIDENTIAL
TREATMENT] in the Territory, ORBCOMM may permit Licensee [CONFIDENTIAL
TREATMENT].


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
   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:

                        (i)       A "Multinational Account" shall be defined as
         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
   21
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
Account Customers customer assistance services comparable to the customer
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,
access to and use of the Licensee System by a Multinational Account Customer,
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.

SECTION 11 - PROPER OPERATION OF THE LICENSEE SYSTEM

         (a)            Performance of Tests.  If, subsequent to the initial
System Acceptance Test, in ORBCOMM's reasonable opinion, there are grounds to
believe that the Licensee System is not operating in accordance with the
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.


SECTION 12 - TERM OF AGREEMENT

         (a)            Term.  Subject to the provisions set forth in Section
11 and this Section 12, 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 license fee in any form for such extension.

         (b)            Termination.

         (i)            Termination by Licensee.  Subject to the provisions of

   23
                        (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

         law, whether domestic or foreign, or liquidate or wind up, voluntarily
         or otherwise.

         hinders normal operation of the





                                    Page 23
   24
         ORBCOMM System or prohibits receipt by ORBCOMM of any fees or amounts
         due to ORBCOMM hereunder;

                        (I)       Licensee shall take any action or fail to
         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
         located or in the United States;

         occurred under the Ground Segment Facilities Use Agreement; or

                        (N)       An event of default by Licensee shall have
         occurred and remain uncured or not waived under the Software License

Agreement by Licensee for convenience pursuant to Section 12(b)(i) or by
ORBCOMM as a result of a Licensee Event of Default, to the fullest extent
permitted by law, ORBCOMM shall be entitled to, in its sole discretion, take
over the operation of the Licensee System and manage it after termination of
this Agreement 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 a license for the
Territory and is ready to start operations.

construct or operate the ORBCOMM System.  In the event ORBCOMM or its
Affiliates (including 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 90 days
written notice, provided that Licensee shall have the right, together with all
other persons who may have a similar right, to purchase the tangible assets of
the ORBCOMM System owned by ORBCOMM Global at their then fair market value,
which right shall be exercised by Licensee within three months of receipt of
written notice from ORBCOMM of abandonment.

forth in Sections 3(a)(vi), 14(a)(ii), 14(b)(ii), 15, 17, 18 and 20(d), (j) and
(n) and those obligations that relate to any amounts due and owing for any
periods prior to termination or expiration of this Agreement shall survive such
termination or expiration.


SECTION 13 - CHANGE OF CONTROL

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

         (b)            After Term.  In the event Licensee terminates this
Agreement in accordance with Section 12(b)(i) for its convenience, or if
ORBCOMM terminates this Agreement because of the occurrence of a Licensee Event

date of such termination, neither it nor any of its shareholders that own, at
the time of the termination of this Agreement, at least 10% of Licensee's
securities entitled to vote generally in the election of directors or persons
who hold similar positions shall engage or participate in, assist or have an
interest in, directly or indirectly, the operation, management or conduct of
any business or enterprise, other than the Licensee System, that provides or
intends to provide satellite-based, two-way data communications or position
determination services using radio frequencies below 1 GHz for communications
directly between satellite(s) and subscriber communicators.


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
ORBCOMM System has Intermittent Service Problems aggregating 180 full days in
each of three consecutive years, Licensee shall be entitled to terminate this
Agreement upon written notice to ORBCOMM.

         (b)            If ORBCOMM determines in its sole discretion that the
ORBCOMM System has permanently and irrevocably failed such that Licensee cannot
access the ORBCOMM System, ORBCOMM shall be entitled to terminate this

SECTION 17 - DISCLAIMER OF WARRANTIES AND LIMITATION OF LIABILITY

         (a)            Disclaimer of Warranties.  EXCEPT AS EXPRESSLY PROVIDED
IN SECTION 4(g) OR SECTION 14(b), TO THE FULLEST EXTENT PERMITTED BY 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, THE GROUND SEGMENT HARDWARE, THE RELATED SERVICES, THE OTHER SERVICES
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
   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
THE ORBCOMM SYSTEM, THE GROUND SEGMENT HARDWARE, THE RELATED SERVICES, THE
OTHER SERVICES OR ANY SERVICES AND/OR PRODUCTS PROVIDED BY OR THROUGH ANY OF
THE ORBCOMM ENTITIES UNDER THIS AGREEMENT; (iv) ANY OBLIGATION, LIABILITY,
RIGHT, CLAIM OR REMEDY 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 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

         (b)            Successors and Assigns.  This Agreement shall be
binding upon the parties, their successors and permitted assigns.  Subject to
Section 13, neither this Agreement nor any interests or duties of Licensee
hereunder may be assigned (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 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.

         (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
December 19, 1995 and each agrees to observe the provisions thereof.

         (k)            Communication in English.  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 reserves 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 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.
