conditions herein set forth.

         2. RENT.

                  (a) BASE RENT. In exchange for the leasehold interest of the
goracing Equipment, goracing shall pay IIS $8,000 per month (the "Base Rent"),
which shall be due and payable on the 1st day of each month beginning on April

                  (b) ADJUSTMENTS TO BASE RENT.

                           (i) FIRST FLOOR RETAINED PREMISES EXPANSION RIGHT. In
the event that IIS exercises its First Floor Retained Expansion Right (as
defined in Section 5 of the Hohokam Sublease) the Base Rent shall be reduced by

                           (ii) SURRENDER OF FIRST FLOOR RETAINED PREMISES. In

effective.

                           (iii) SECOND FLOOR RETAINED PREMISES EXPANSION RIGHT.
In the event that IIS exercises its Second Floor Retained Expansion Right (as

the event that Action surrenders its right to the Second Floor Retained Premises
(as defined in Section 3(C) of the Hohokam Sublease) the Base Rent shall be

         3. TERM.

                  (a) BASE TERM. goracing's rights and obligations under this
Sublease shall commence as of the date set forth above and shall expire upon the
Expiration Date of the Hohokam Sublease (as defined in Section 1(H) of the
Hohokam Sublease).

                  (b) ADJUSTMENTS TO THE TERM. In the event that IIS exercises

of the Equipment located in or associated with the respective retained or
surrendered area, shall be reduced to the effective date of such exercise or
surrender.

                  (c) AUTOMATIC TERMINATION. In the event that Action's
occupancy of the Premises is completely terminated in accordance with the terms
and conditions of the Hohokam Sublease, this Sublease shall simultaneously, and

full by IIS on or before five (5) days after the date any such payment is due,
then goracing shall pay to IIS a late payment charge in the amount of ten
percent (10%) of the amount then due. This provision shall not be construed to
allow or permit goracing to make payments after the due date, or to waive any of
IIS's rights in connection with late payments made by goracing.

hereunder or with regard to the Base Equipment Leases shall be in writing and
