material respect with any of the provisions of this Agreement and to correct
such failure, within sixty (60) days from the date of OHB's receipt of written
notice thereof from ORBCOMM authorized representative setting forth in detail
ORBCOMM basis for termination of the Agreement; or (c) termination of ORBCOMM's
prime contract by ORBCOMM's customer, the United States Government.

(c) OHB shall be in default under this agreement if it fails to deliver the
goods covered hereunder, or does so beyond a reasonable time, or delivers goods
of a quality differing from or inferior to the referenced applicable
specifications.

(d) OHB shall be in default under this Agreement in the event that OHB fails to
comply with any applicable federal, state or local laws pertaining to the
subject matter of this Agreement or the work required to fulfill the
requirements of this Agreement.

(e) This order may be unilaterally terminated by ORBCOMM for default by OHB
without prejudice to any claim for damages or other relief arising out of such
default.

(f) This order or, at the option of the ORBCOMM, individual orders placed

Section 10.2  - Remedies Upon Termination.
(a) In the event of termination of this Agreement by ORBCOMM as provided for
hereinabove, OHB shall:

(i) At ORBCOMM's request, to the extent it is permitted to do so by law,
regulation and any third party obligations pertaining thereto, deliver to
ORBCOMM all completed items to be delivered under Article 2, work-in-process,
drawings, and other technical data associated with the Work developed as part of
the performance of the completed Milestones of this Agreement along with
appropriate licenses to the intellectual property embodied in all such items,
drawings and other technical data sufficient to enable ORBCOMM to use, make and
have made such items, as would have been required as a deliverable had the work
continued to completion, provided that such data and licenses shall be used
exclusively for purposes related to the ORBCOMM System and shall be subject to
appropriate confidentiality obligations.

(ii) At ORBCOMM's request and to the fullest extent permitted by law, and
subject to applicable laws, regulations and terms of this Agreement, transfer
the applicable approvals, permits, and licenses pertaining to the goods
delivered under this Agreement.

(iii) Take all commercially reasonable steps to protect and preserve the
property referred to in (i) above in the possession of OHB until delivery to
ORBCOMM.

(iv) In the event this agreement is terminated as a result of a termination for
convenience of the United States Government prime contract in support of which
this agreement has been entered, provide to ORBCOMM as soon as possible but in
any event not later than ninety (90) days after receipt of notice of such
termination for convenience, a certified statement of all damages for which it
will require ORBCOMM to seek reimbursement from the Government. In such event,
OHB shall retain all Milestone payments received to date and be reimbursed for
all costs (including a reasonable fee thereon) that are in excess of Milestone
payments received and for which ORBCOMM is able to obtain payment from the
United States Government. OHB shall cooperate fully with the United States
Government and ORBCOMM regarding the presentation of a termination for
convenience request for payment, including but not limited to providing all
required certifications and permitting all required United States Government
audits in conjunction therewith. ORBCOMM shall present the OHB termination for
convenience costs to the Government and shall use its best efforts to permit OHB
to be able to participate directly with the Government in the negotiation of
those termination for convenience costs which pertain to OHB.

Concept Demonstration Satellite Bus Integration Test
And Launch Services Procurement Agreement

In such event, ORBCOMM shall not be responsible to pay to OHB any damages other
than those which it is able to collect from the United States Government as a
result of the termination for convenience request for payment.

(v) In the event this Agreement is terminated solely for the convenience of
ORBCOMM (and not due to the termination of the relevant United States prime
contract), OHB shall be entitled to retain all Milestone payments received to
date and shall further be entitled to be reimbursed for all costs (including a
reasonable fee) in excess of such Milestone payments that have been incurred by
OHB in support of this Agreement. OHB shall have the obligation to mitigate all
such costs to the extent such mitigation is possible.

(vi) In the event that this Agreement is terminated for Default, ORBCOMM shall
be obliged to mitigate the damages sustained as a result of such default by OHB
to the extent permitted by the Contract. If ORBCOMM elects to complete the
undelivered items specified in the Agreement, OHB will be responsible for the
re-procurement cost of the remaining undelivered items. If ORBCOMM elects not to
complete the undelivered items specified in the Agreement, ORBCOMM and OHB shall
agree on the disposition and amount of payment for undelivered manufacturing
materials decided by the parties to be delivered to ORBCOMM. If ORBCOMM is
required to seek an alternate source for the terminated items in order to comply
with the requirements of the Contract, OHB will be responsible to reimburse
ORBCOMM for all costs associated with the acquisition from such alternate
source. Failure to agree will be a dispute under Article 12.3. OHB shall hold
ORBCOMM harmless and indemnify ORBCOMM from any and all claims demands,
assessments and all liabilities and costs related thereto for which ORBCOMM
becomes liable, including but not limited to any assessment of damages and/or
reprocurement costs by the United States Government.

(b) Any disagreement under this provision, including disagreements with respect
to ORBCOMM's right to seek a termination and the appropriate remedies for
termination, shall be resolved in accordance with Article 12.3 of this
Agreement.

be likely to be delayed for a period in excess of __ days, ORBCOMM at its sole
option shall be entitled to terminate this agreement. In such event, OHB shall
be entitled to be compensated in accordance with the provisions of Article
10.2(a)(i),(ii), (iii) and (v) infra.

Section 12.3 - Resolution of Disputes. (a) Any controversy or claim that may

of a dispute, ORBCOMM shall communicate the concern to OHB's senior management
to negotiate a mutually agreed upon alternative. Notwithstanding its role in
reviewing Key personnel adjustments, ORBCOMM shall have no supervisory control
over Key Personnel work, and nothing in this Section 12.7 shall relieve OHB of
any of its obligations under this Agreement, or of its responsibility for any

the amount requested. Payments shall be due net 30 days.

For all invoices for time and material tasks, Orbital shall provide a
certificate, signed by the Vice President and Controller of Orbital or by any
other officer designated by the Vice President and Controller of Orbital,
certifying the accuracy of the costs incurred that are the subject of the
respective invoice. The invoices shall include, but not be limited to, a listing
of labor costs, including labor hours by bid rate group, material subcontracts
and ODC's as to enable ORBCOMM to fully comprehend the total monthly charges
being invoiced by Orbital. Invoices shall be submitted to the following address:

  ORBCOMM, Inc
  Attn: Controller
  21700 Atlantic Blvd.
  Dulles, VA   20166

Section 5.2 - Milestone Achievement. (a) A Milestone shall be deemed achieved
upon the successful demonstration by Orbital that the Work that is the subject
of the Milestone has been completed in accordance with the requirements of this
Agreement, and that all conditions established by this Agreement as
prerequisites to payment of the invoice have been fulfilled to ORBCOMM's
reasonable satisfaction.

(b) In the event that Orbital fails to achieve any Milestone on or before the
scheduled completion date shown in Exhibit B, ORBCOMM shall be relieved of its
obligation to pay the applicable amounts specified for such Milestone until such
time as Orbital achieves such Milestone or obtains a waiver in writing from
ORBCOMM for such achievement. Orbital's failure to timely complete any Milestone
shall not relieve ORBCOMM from its obligation to pay for other achieved
Milestones.

(c) If ORBCOMM 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's receipt of Orbital's
response, in writing, addressing in detail each of ORBCOMM's exceptions;
provided however, if with respect to any such Milestone, ORBCOMM reasonably
concludes that Orbital's response to ORBCOMM's exceptions to be non-responsive
and so notifies Orbital as provided in Subsection 5.5 (c) (i) below, ORBCOMM
may, at its sole discretion, defer any unpaid amount of the relevant Milestone
payment until the resolution of the matter as described in Subsection 5.3(c)(i)
below.

(i) In the event ORBCOMM concludes that Orbital has been non-responsive to
ORBCOMM `s exception to a Milestone, ORBCOMM shall notify Orbital thereof in
writing (the "Exception Notification") within ten (10) business after receipt of
Orbital's response to ORBCOMM written exception. The Exception Notification
shall (A) specify in detail the reason(s) ORBCOMM believes Orbital's response to
be non-responsive, and (B) advise Orbital formally that ORBCOMM intends to
withhold payment for such Milestone(s). On receipt of an Exemption Notification
from ORBCOMM, Orbital shall have thirty (30) days to demonstrate the achievement
of the relevant

<PAGE>

Milestone to the reasonable satisfaction of ORBCOMM. If Orbital is unable to
make such a demonstration, ORBCOMM may defer payment as provided above. If
Orbital continues to dispute the OBRCOMM assertions of non-compliance, either
party may, at any time after the filing of the Orbital additional response as
permitted by this Section 5.3 (c)(i), submit the matter to be resolved by
arbitration as provided in Section 12.3 hereof.

Section 5.3 - Certification and Auditor Review of Submitted Invoices. In order
to assure ORBCOMM that the invoices that are submitted accurately reflect (i)
the actual hours expended, and actual cost incurred for travel expenses,
material and other direct cost (ODC) for T&M payments, and (ii) the correct
Milestone completion effort to be invoiced under the terms of this Agreement,
Orbital will provide with each invoice a certification executed by the Vice
President of Orbital's Space Systems Group that the sums invoiced are current,
complete and accurate and that they are allowable and allocable to the invoice
being presented and to this contract. If the United States Government should
require that invoices be certified in addition to the above referenced
certification, Orbital shall provide such other Government required
certifications as are required. ORBCOMM may request the Government to 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 was
overcharged, the amount of the overcharge shall be determined by the auditors
and the overcharged amount, shall be refunded to ORBCOMM within thirty (30)
business days from the date of notification by the auditors. To the extent that
Orbital does not agree with the auditors' determination, such dispute shall be
settled in accordance with Section 12.3.

ARTICLE 6 - ACCESS AND ACCEPTANCE

Section 6.1 - Access. Subject to the receipt of any and all required
governmental approvals, ORBCOMM authorized representatives shall have the right,
on a not-to-interfere basis, at all reasonable times during the performance of
this Agreement, to monitor the Work in progress (including without limitation
all test activities with access to related computer program information to the
extent reasonable safeguards can be implemented) at the plant(s) of Orbital.
Orbital shall use all commercially reasonable efforts to incorporate in all of
its subcontracts Orbital's and ORBCOMM's rights to monitor work in progress as
provided herein, provided that any additional direct expenses associated with
the exercise or implementation of such rights shall be borne by ORBCOMM.

Section 6.2 - Inspection and Acceptance. ORBCOMM authorized representatives
shall promptly conduct a final inspection of the Demo Payload and any Option
Payloads ordered in accordance with the Verification and Test Plan or, at
ORBCOMM's option, witness such inspection by Orbital and shall either approve
them for acceptance in writing or promptly notify Orbital in writing of the
particulars in which they are non-conforming with the applicable Specifications.
If no objections have been sent by ORBCOMM within (15) days of the inspection,
the relevant payload shall be deemed to have received approval for acceptance by
ORBCOMM. Corrections required to render the payloads in conformance with the
applicable Specification shall be made by Orbital at its cost. The decision how
to make the corrections shall be at Orbital's sole discretion and an item found
to be non-conforming during or after testing performed under this Agreement
shall at ORBCOMM's request and without charge to ORBCOMM be retested by Orbital
after Orbital has remedied the non-conformance. ORBCOMM may be assisted in all
inspections by its consultants or advisors. This final inspection and acceptance
shall take place at Orbital's Dulles facility prior to delivery to ORBCOMM.

Section 6.3. - Corrections in Delivered Payloads. (a) If at any time, either
Orbital or ORBCOMM becomes aware that any payloads delivered under this contract
are defective as a result of the operation of on-orbit Satellites which
defect(s) has resulted from a defect in workmanship or materials or adherence to
the statement of work or specification then the following shall occur: (i)

<PAGE>

if the discovery is made by Orbital, Orbital shall notify promptly ORBCOMM of
such defects and to the extent that ORBCOMM determines that such defects would,
in the reasonable opinion of ORBCOMM materially adversely affect the operation
of the ORBCOMM AIS System. Orbital shall take prompt and appropriate corrective
measures to eliminate any such defects from all unused payloads, or (ii) if the
discovery is made by ORBCOMM, ORBCOMM shall notify promptly Orbital of such
defects that would, in the reasonable opinion of ORBCOMM, materially and
adversely affect the operation of the ORBCOMM AIS System. Orbital shall be
obligated within ten days to verify and respond to the ORBCOMM notification of
defective delivered and not yet launched payloads, and, in the event the defect
has been verified, Orbital shall take prompt and appropriate corrective measures
to eliminate any such defects from all such payloads. The decision how to make
the corrections shall be mutually agreed upon by ORBCOMM and Orbital.

(b) If the defects so identified are not the result of any failure to adhere to
the applicable specifications and SOW on the part of Orbital, ORBCOMM shall pay
the costs of such corrections identified in Section 6.3(a) and Orbital shall
charge for the effort expended on such corrections; provided however, that if
the material defect is found as a result of on-ground testing of the payloads by
Orbital or Orbital's subcontractors, then the corrections shall be deemed to be
in the Scope of Work. Orbital's obligation to correct such material defects in
the payloads shall end the sooner of Twelve (12) months after acceptance of the
hardware by ORBCOMM or launch. After such date corrections to such payloads
shall be made at a price mutually agreed to by ORBCOMM and Orbital. ORBCOMM
shall decide whether to proceed with the corrections of such material defects.
If the defects so identified result from the failure of Orbital to adhere to the
applicable specifications and/or SOW, then Orbital shall be responsible to
correct the defect in workmanship and/or material at no increase in Contract
price.

services required to be performed hereunder.

Section 8.2 - Adjustments to Agreement. (a) If any change causes an increase or
decrease in the Price, or in the time required for performance of any part of
the Work, whether or not directly changed by the order, ORBCOMM and Orbital
shall negotiate an equitable adjustment to such Price, delivery schedule or
other provision of this Agreement. Orbital shall perform the Work as changed
pending resolution of any negotiation under this Article 8.

extent permitted by the Contract. If ORBCOMM elects to complete the undelivered
items specified in the Agreement, Orbital will be responsible for the
reprocurement cost of the remaining undelivered items up to the value of those
undelivered items as specified in this Agreement, and, if requested by ORBCOMM,
Orbital will, for the sole purpose of enabling ORBCOMM to complete the
undelivered items specified in the Agreement, make available to ORBCOMM
Foreground and Background Information necessary to enable ORBCOMM or its
designee to complete the items. Orbital will permit use of the aforementioned
Foreground and Background Information by ORBCOMM's designee only after Orbital
has been notified of ORBCOMM's intentions to make such Information available to
a third party and Orbital and ORBCOMM's designee have executed a non-disclosure
agreement, which will be in substantially the same form as that non-disclosure
agreement which exists between Orbital and ORBCOMM at the time of execution of
this Agreement, to protect such Information If ORBCOMM elects not to complete
the undelivered items specified in the Agreement, ORBCOMM and Orbital shall
agree on the disposition and amount of payment for undelivered manufacturing
materials decided by the parties to be delivered to ORBCOMM. Failure to agree
will be a dispute under Section 12.3. If, after termination, it is determined
that Orbital was not in default, or that the default was excusable, the rights
and obligations of the parties shall be the same as if the termination had been
issued for the convenience of the Government.

(b) Any disagreement under this provision, including disagreements with respect
to ORBCOMM's right to seek a termination and the appropriate remedies for
termination, shall be resolved in accordance with Article 12.3 of this
Agreement.

ARTICLE 11 - OWNERSHIP OF INTELLECTUAL PROPERTY

Section 11.1 (a) Except as set forth in Sections 11.1(b) and 11.1(c) and except
as required by the terms of the Prime Contract, all foreground IP related to the
Work is the exclusive property of ORBCOMM. All rights, title and interest in and
to all background IP relating to the Work shall remain exclusively in Orbital
and/or its subcontractors, notwithstanding Orbital's disclosure of any
information or delivery of any data items to ORBCOMM or ORBCOMM's payment to
Orbital for engineering or non-recurring charges. ORBCOMM shall not use or
disclose such information or property to any third party other than as required
by the terms of the Prime Contract without the prior written consent of Orbital.
Title to all tools, test equipment and facilities not furnished by ORBCOMM or
specifically paid for by ORBCOMM and delivered to ORBCOMM under this Agreement
shall remain in Orbital and/or its subcontractors. Foreground information is
defined as that data, regardless of format, that is first conceived, developed
or produced by Orbital in the performance of this Agreement. Background
information is defined as data, regardless of format, and inclusive of all
technical information trade secrets, and proprietary information that was
conceived, developed or produced by Orbital prior to performing under this
Agreement or outside of the efforts required by this Agreement.

Section 11.2 To the extent that computer software, source codes, programming
information and other related documentation relating to the Work, (the
"Background Information") are not deliverable data under this Agreement (or to
the extent that they are deliverable data, that no ownership or license rights
are being transferred to ORBCOMM), Orbital, to the extent that it has

<PAGE>

the right to do so, shall provide to ORBCOMM on an as needed basis, the right to
access and copy such Background Information to support its analysis of the
ORBCOMM System, to develop alternative solutions for technical problems
affecting the operation and management of the ORBCOMM AIS System and to design
modifications to the Background Information but in any event, not for any
re-procurement. To the extent that ORBCOMM designs modifications to the
Background Information it shall not have the right to implement such
modifications without the prior written consent of Orbital, which consent shall
not be unreasonably withheld.

Section 11.3 Each party grants to the other party a worldwide fully paid
non-exclusive license for use of the other party's intellectual property as
defined in Sections 11.1 and 11.2 for purposes of performing the Work under this
Agreement.

act of God, terrorism, riot, or other hostilities, act of the public enemy,
embargo, governmental act, orders or regulations, 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 necessitated by such circumstances. Failure to agree on
an equitable extension shall be considered a dispute and resolved in accordance
with Section 12.3 hereof.

Section 12.3 - Resolution of Disputes. (a) Any controversy or claim that may
arise under, out of, in connection with or relating to this Agreement or any
breach hereof, shall be submitted to a representative management panel of
ORBCOMM and Orbital. Each of ORBCOMM and Orbital

<PAGE>

may appoint up to two (2) individuals to each 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 individuals by way of unanimous decision, either
party may remove the controversy or claim for arbitration in accordance with
Section 12.3(b).

(b) Any controversy or claim that is not resolved under Section 12.3(a) shall be
settled by final and binding arbitration in Washington, D.C., 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 12.3. 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. Unless otherwise agreed by the parties, 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 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
shall not agree upon the appointment of the third arbitrator, such chairman
shall be selected by the AAA. In all cases, the arbitrators shall be fluent in
English. Judgement 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 12.4 - 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 12.5 - 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 (by operation of law or otherwise) to
any person without the prior written consent of the other party, provided that
any party may assign this Agreement and its interest and obligations hereunder
to any wholly owned subsidiary of such party.

Section 12.6 - Order of Precedence. Inconsistencies between or among Articles of
Agreements and/or any attachment shall be resolved in the following order of
precedence:

 (a) Article 1 through Article 12 of this Agreement
 (b) the Statements of Work: and
 (c) the Specifications.

Section 12.7 - Key personnel. Orbital agrees that those individuals identified
in Exhibit C are necessary for the successful completion of the work to be
performed under this Agreement. Such key personnel shall be removed only after
proper advanced (two weeks minimum) consultation with ORBCOMM. Advanced
consultation shall include identification/qualifications of the replacement and
a transition plan. Orbital shall take considerable effort to replace Key
Personnel with personnel of substantially equal qualifications and ability. In
the event of a dispute, ORBCOMM shall communicate the concern to Orbital's
senior management to negotiate a

<PAGE>

mutually agreed upon alternative. Notwithstanding its role in reviewing Key
personnel adjustments, ORBCOMM shall have no supervisory control over Key
Personnel work, and nothing in this Section 12.7 shall relieve Orbital of any of
its obligations under this Agreement, or of its responsibility for any acts or
omissions of its personnel. To the extent that the Key Personnel voluntarily
resign, ORBCOMM shall be consulted in the selection of the replacement personnel
but shall not have the right to approve such replacement personnel.

Section 12.8 - Counterparts. This Agreement may be executed in any number of
counterparts of the signature pages, each of which shall be considered an
original, but all of which together shall constitute one and the same
instrument.

Section 12.9 - Headings. This section and other headings contained in this
Agreement are for reference purposes only and shall not affect the meaning or
interpretation of this Agreement.

Section 12.10 - Amendment Waiver. Except as provided otherwise herein, this
Agreement may not be amended nor may any rights hereunder by waived except by an
instrument in writing signed by the parties hereto.

Section 12.11 - Entire Agreement. This Agreement and all exhibits (which are
hereby made part of this Agreement) contain the entire understanding between the
parties and supersede all prior written and oral understandings relating to the
subject hereof. No representations, agreement, modifications or understandings
not contained herein shall be valid or effective unless agreed to in writing and
signed by both parties.

Section 12.12 - Modification and Termination. This order may not be modified or
terminated orally. No claimed modification, termination or waiver of any of its
provisions shall be valid UNLESS in writing signed by ORBCOMM.

Section 12.13 - Government Contract Conditions Since this order is being placed
in support of the United States Government contract referenced above, this order
is subject to the following additional provisions:

(a) The terms and conditions of the United States Government Contract;

(b) Inspection at Source: ORBCOMM reserves the right to request Government
Inspection at source. In the event this right is exercised, Orbital shall make
all necessary arrangements with the appropriate Government Agency for such
inspection and shall promptly furnish ORBCOMM with the resultant inspection
certificate(s); and

(c) Government Regulations: The provisions of the Federal Acquisition
Regulations and Defense Department Supplement thereto are incorporated herein by
reference as attached hereto at Exhibit "D." Where necessary to make the context
of these provisions applicable to this order, the term "Government" and
equivalent phrases shall include ORBCOMM, the term "Contractor" shall include
Orbital, and the term "Contract" shall refer to this order. Orbital however,
reserves the right of audit solely to the Government. Where any reference above
contains alternative clauses, that alternative shall apply which is required by
or most consistent with ORBCOMM's prime or subcontract pursuant to which this
order is issued. The clauses set forth above shall be interpreted as referring
to the FAR or DFAR clause with the same or similar name in effect (including
revision by Defense Acquisition Circular) as of the date set forth on ORBCOMM's
prime or subcontract regardless of title or FAR/DFAR numbering. In the event
that this order is placed for a "commercial" product(s) as defined in FAR
52.202-1, only the provisions of the Federal Acquisition Regulations and Defense
Department Supplement thereto set forth at Attachment "A" hereto which are
applicable to commercial item acquisitions shall be applicable hereto. See in
general FAR 52.244-6 and DFAR 252.225.7012.

<PAGE>

Section 12.14 - Equal Opportunity. Orbital agrees during the performance of this
order, pursuant to 41 CFR Section 60-1.4, unless otherwise exempted by law,
rules, regulations, or orders of the United States Government:

1) Orbital will not discriminate against any employee or applicant for
employment because of race, color, religion, sex, or national origin. Orbital
will take affirmative action to ensure that applicants are employed, and that
employees are treated during employment without regard to their race, color,
religion, sex, or national origin. Such action shall include, but not be limited
to the following: Employment, upgrading, demotion, or transfer, recruitment or
recruitment advertising; layoff or termination; rates of pay or other forms of
compensation; and selection for training, including apprenticeship. The Orbital
agrees to post in conspicuous places, available to employees and applicants for
employment, notices to be provided by the contracting officer setting forth the
provisions of this non-discrimination clause.

(2) Orbital will, in all solicitations or advertisements for employees placed by
or on behalf of the Orbital, state that all qualified applicants will receive
consideration for employment without regard to race, color, religion, sex or
national origin.

(3) Orbital will send to each labor union or representative of workers with
which it has a collective bargaining agreement or other contract or
understanding, a notice to be provided by the agency Contracting Officer
advising the labor union or worker's representative of Orbital's commitments
under section 202 of Executive Order 11246 of September 24, 1965, and shall post
copies of the notice in conspicuous places available to employees and applicants
for employment.

(4) Orbital will comply with all provisions of Executive Order 11246 of
September 24, 1965, and of the rules, regulations, and relevant orders of the
Secretary of Labor.

(5) Orbital will furnish all information and reports required by Executive Order
11246 of September 24, 1964, and by the rules, regulations, and orders of the
Secretary of Labor, or pursuant thereto, and will permit access to its books,
records, and accounts by the contracting agency and the Secretary of Labor for
purposes of investigation to ascertain compliance with such rules regulations,
and orders.

(6) In the event of Orbital's non-compliance with the nondiscrimination clauses
of this order or with any of such rules, regulations, or orders, this order may
be canceled, terminated or suspended in whole or in part and Orbital may be
declared ineligible for further Government contracts in accordance with
procedures authorized in Executive Order 11246 of September 24, 1965, and such
other sanctions may be imposed and remedies invoked as provided in Executive
Order 11246 of September 24, 1965, or by rule, regulation, or order of the
Secretary of Labor, or as otherwise provided by law.

(7) Orbital will include the provisions of paragraphs (1) through (7) in every
subcontract or purchase order unless exempted by rules, regulations, or orders
of the Secretary of Labor issued pursuant to section 204 of Executive Order
11246 of September 24, 1965, so that such provisions will be binding upon each
subcontractor or vendor. Orbital will take such action with respect to any
subcontract or purchase order as may be directed by the Secretary of Labor as a
means of enforcing such provisions including sanctions for noncompliance:
Provided, however, that in the event Orbital becomes involved, in, or is
threatened with, litigation with a subcontractor or vendor as a result of such
direction, the Orbital may request the United States to enter into such
litigation to protect the interests of the United States.

and willfully makes any false, fictitious or fraudulent representations to the
United States Government either directly or indirectly may be liable to criminal
prosecution under 18 U.S.C. 1001.

Section 12.17 Certification Regarding Debarment, Suspension, Proposed Debarment
and Other Responsibility Matters.

or subcontract, Orbital herewith certifies to the best of its knowledge and

civilly charged by a government entity with, commission of any of the offenses
enumerated above. The Orbital has ( ) has not ( ), within a three year period

head of a subsidiary, division or business segment, and similar positions).

Section 12.18 Severability. If any term, condition, clause or provision of this
order shall be determined or declared to be void or invalid in law or otherwise,
then only that term, condition, clause or provision shall be stricken from this
order and in all other respects this order shall be valid and continue in full
force, effect and operation.

Section 12.19 Waiver. The failure of ORBCOMM at any time to insist on
performance of any provision of this order shall not be construed as a waiver of
that provision in any later instance, nor shall it be construed as a waiver of
any other provision of this order.

Section 12.20 Limitation of Liability. In no event shall either party hold the
other liable for incidental, consequential or punitive damages.
