                  RVP and USX share common ownership. RVP has leased the

follows:

                  1. Use of the Premises. RVP agrees to allow USX to occupy a
portion of the Premises as is mutually agreed upon by RVP and USX from time to
time. On a monthly basis, USX shall reimburse RVP for its proportionate share of
the previous month's rental costs, utility costs, janitorial costs, insurance
costs, telephone costs, office supplies costs and any other similar direct costs
based upon the percentage square footage of the Premises occupied by USX as
compared to the total square footage of the Premises. Such payment shall occur
on or before the 15th day of each month and shall be based upon an estimate of
such costs as determined by RVP.

                  2. Use of RVP Employees. RVP agrees to allow USX to utilize
the services of certain employees of RVP. Attached as Exhibit A is a list of
those employees and the estimated percentage of their time which will be devoted
to USX endeavors. It is contemplated that Exhibit A shall be updated from time
to time by the parties. On a monthly basis, USX shall reimburse RVP for its
proportionate share of the previous month's compensation and employee benefit
costs for such employees based upon the percentage contained on Exhibit A. Such
payment shall occur on or before the 15th day of each month and shall be based
upon an estimate of such costs as determined by RVP. Each employee listed on
Exhibit A shall continue solely as an employee of RVP and, other than as set
forth above, RVP shall be responsible for all salaries, taxes, employee benefits
and related costs and expenses in connection with such employees.
