liability, for the accuracy, completeness or timeliness of any advice or
service or any report, filing or other document that it or any of them

                 Subject to the provisions of Section 4 hereof, the term of
this Agreement shall commence on March 23, 1998 and shall continue so long as
any of the categories of Services or Office Space is provided by ORBCOMM Global

Services or the Office Space on furnishing ORBCOMM Global ninety (90) days
prior written notice.  On termination of this Agreement for any reason, ORBCOMM

SECTION 4 - PRICE

                 Section 4.1 - Office Space.  The total price per month for the

compensate ORBCOMM Global for the Use and Occupancy Services as described in

pay and miscellaneous leave). On the Company's request, ORBCOMM Global shall
provide monthly to the Company a budget versus actual variance report in order
to update the status of pool expenses.  When the Company is no longer receiving
