          or other product using the Patented Technology. Such records will
          include general ledger records in sufficient detail to enable the
          royalties/sales fee payable hereunder to be determined. Each party
          further agrees to permit its books and records to be examined by the
          other party from time to time to the extent necessary to verify
          reports provided for royalty/sales fee calculations. Such examination
          is to be made by the parties or their designee (must be an accounting
          firm acceptable to party to be audited), at the expense of auditing
          party, except in the event that the results of the audit reveal an
          underreporting of royalties/sales fee of ten percent (10%) or more,
          then the audit costs shall be paid by the audited party. The auditing
          party and/or its designee must execute a non-disclosure agreement to
          limit their use of the knowledge that they may learn during said
          audit.

     8.   Termination for Default
          -----------------------

          A.  Either party may terminate this Agreement if the other party
              should materially default in the performance of its obligations
              under this Agreement. The party claiming that a material breach of
              the Agreement has occurred must provide written notice of the same
              to the other party with supporting documentation. The alleged
              defaulting party must respond within fifteen working days either
              refuting the "claim of the material breach" or cure the material
              breach within the fifteen working days. Unless the matter is
              resolved to the satisfaction of both parties within the fifteen
              working days, the following shall be applicable:

              (1). The parties shall meet at ARINC's facility in Annapolis,
              Maryland within the next fifteen working days to determine if
              their differences can be resolved. If they cannot be, then the
              party claiming that the other has materially breach its Agreement
              shall arrange for an arbitration hearing per the following:

                    (a). The dispute will be submitted to arbitration conducted
              in accordance with the Commercial Arbitration Rules of the
              American Arbitration Association then in effect. The decision of
              the Arbitration Committee shall be considered as final and neither
              party shall appeal such decision to any court. Any court having
              jurisdiction thereof may enter judgment upon the award rendered by
              the Arbitrators. The Arbitrators award may include compensatory
              damages against either party but under no circumstances will the
              Arbitrators be authorized to nor shall they award consequential,
              incidental, special or multiple damages against either party. The
              Arbitration hearing shall be conducted in Washington D.C.

              B. The above shall be applicable for all matters except
              infringement which is covered in Section 5 A-C inclusive of this
              Agreement.

     9.   Assignment
          ----------

              Neither Party may assign its rights or delegate its
              responsibilities under this Agreement without obtaining the prior
              written consent of the other except (i) in connection with a
              merger or consolidation with another entity where the surviving
              entity is at least as financially and technically competent as
              its predecessor or (ii) to a wholly owned subsidiary, to a wholly-
              owning parent corporation or an affiliated company with common
              ownership where the predecessor remains liable as a

                                       9

              right reserved to it, or to require performance of any of the
              terms, covenants, or provisions hereof by the other party at the
              time designated, shall not be a waiver of any such default or
              right to which the party is entitled, nor shall it in any way
              affect the right of the party to enforce such provisions

              written, between the Parties relating to the subject matter of
              this Agreement. This Agreement cannot be modified or altered
              except by a written instrument duly executed by authorized
              executive officers of both Parties.

     15.      Non-solicitation of Employees
              -----------------------------

              During the term of this Agreement, no organizational unit of
              either Party working under this Agreement shall solicit employees
              of the other without the other Party's prior written
              authorization.

                              Hawks/ARINC Antenna
                         (Dominium PN: XXX-N-AN-00300)

Operational/Performance/Physical Requirements for Agreement to Purchase:

1.  Description: Low-Profile antenna that provides both ORBCOMM VHF (transmit
    and receive) and GPS (receive) capability.

2.  Size/Form:

    A.  Antenna (with enclosure) no larger than 6.5" L x 4.5" W x 0.7" H
    B.  Enclosure shall have external RF cables permanently attached via sealed
        penetrations to provide connection to VHF and GPS antennas. The separate
        external cables shall terminate in BNC in-line connectors (VHF shall be
        FEMALE: GPS shall be MALE).
    C.  The enclosure shall have tapered sides
    D.  The enclosure shall have four (4) mounting holes at the corners.
    E.  The enclosure shall have 3M double-sided tape affixed to the bottom
        surface along the edges.

3.  Performance:
    A.  VHF Antenna:
           i.    Shall operate satisfactorily (as defined in vi below) mounted
                 on the top or side of any mobile or fixed "platform" expected
                 in the Dominium market area (e.g., heavy-duty trucking trailers
                 (aluminum or fiberglass tops), shipping containers (steel or
                 aluminum construction), railcars, ships, automobiles, etc).
           ii.   The antenna shall function as two antennas in one physical
                 enclosure: a GPS antenna, and an ORBCOMM antenna.
           iii.  Shall be capable of receiving in the frequency band 137-138
                 MHz, and transmitting in the 148-150.05 MHz band.
           iv.   Shall be capable of handling 5 W of instantaneous transmit
                 power in the transmit band.
           v.    The nominal impedance of the ORBCOMM antenna at the connector
                 shall be 50 (omega symbol).
           vi.   Satisfactory operational performance for the ORBCOMM (VHF)
                 antenna shall be defined as:
                 a.  Average Transmit-Receive Delta T (Delta time) of (less than
                     or equal to) 7 minutes (measured as the difference in time
                     from message TX date/time stamp in the SC to receive
                     date/time at the destination address), with a standard
                     deviation (less than or equal to) 5 minutes.
                     1)  The Transmit-Receive Delta T shall be measured with the
                         SC transmitting at a rate of one 144-byte fixed
                         message every 15 minutes.
                 b.  Successful transmission rate of (greater than or equal to)
                     98% (measured as a percent of successful receptions over
                     all transmissions, excluding external events that prevent
                     successful transmission or reception [e.g., ORBCOMM
                     network, gateway, or satellite outages, ISP outages,
                     etc.]).
                 c.  Successful polling rate of (greater than or equal to) 98%
                     (measured as % of successful acknowledgement receipt at
                     the polling location over all polls sent).
                 d.  Average Polling Delta T of (less than or equal to) 10
                     minutes (measured as the total time from TX of the poll to
                     the SC to receipt of the SC acknowledgement at the sending
                     location).
