        (hereinafter referred to as "IAS")
                                                               OF THE FIRST PART

        of 2000 Bridge Parkway, Suite 201
        Redwood Shores, CA   94065

        (hereinafter referred to as "World Tracking")
                                                              OF THE SECOND PART

WHEREAS:

A.   World Tracking and IAS entered into a License Agreement dated January 31st,
     2000 wherein IAS provided two sample antennas to World Tracking for testing
     for a 30 day period (the "License Agreement");

B.   World Tracking has now completed the testing of the sample antennas and has
     provided written confirmation to IAS that one of the sample antennas has
     been accepted and the second GPS antenna was not suitable to World
     Tracking;

C.   The parties hereto wish to proceed with and consummate the License for one
     of the Antennas only;

NOW THEREFORE, in view of the premises and in consideration of the mutual
covenants and agreements hereinafter set forth, the parties hereto do hereby
covenant and agree as follows:

1.   All defined terms set out in this Agreement shall have the same meaning as
     the defined terms set out in the License Agreement, except that any
     reference to Antenna(s) shall mean only one Antenna.

2.   The parties hereto acknowledge and agree that the Initial Testing has been
     completed by World Tracking and IAS has been advised by World Tracking that
     one of the sample antennas is acceptable and the GPS antenna is not
     suitable to World Tracking.

3.   IAS acknowledges and agrees that since World Tracking has approved only one
     of the two antennas, the non-recurring engineering fee shall be reduced
     from $30,000 to $15,000.

4.   World Tracking acknowledges and agrees that of the $15,000 Retainer paid by
     World Tracking to IAS, $7,500 is now non-refundable and the balance of
     $7,500 shall be non-refundable after delivery by IAS to World Tracking of
     the twenty prototype Antennas.

5.   All other terms and conditions of the License Agreement shall remain
     unchanged and shall be

     binding upon the parties hereto.

6.   If any provision of this Agreement is held by a competent court to be
     invalid, illegal or unenforceable for any reason or in any respect
     whatsoever, such invalidity, illegality or unenforceability shall not
     affect any other provisions of this Agreement, and this Agreement shall be
     construed as if such invalid, illegal or unenforceable provision had never
     been contained herein.  IAS and World Tracking hereby agree, however, to
     negotiate an equitable amendment of this Agreement if a material provision
     is adversely affected.

7.   This Agreement and any modification or waiver of any provision hereof shall
     be binding only if set forth in writing and signed by both parties hereto
     and shall be effective only to the extent set forth in such modification or
     waiver and for the particular occasion.

8.   This Agreement shall be construed, interpreted and applied in accordance
     with the laws of the State of California and the United States of America,
     and all matters shall be resolved solely in the United States of America.

IN WITNESS WHEREOF, the parties hereunder have executed this Agreement on the
21st day of March, 2000.
