5        PAYMENT AND ACCOUNTING RECORDS.

         5.1 All Royalties shall be paid in full within 30 days of each
Quarterly Period. Royalties may be calculated using weighted averages adjusted
annually.

         5.2 Within 30 days after each Quarterly Period in respect of which
Royalties are due under Section 4, LICENSEE shall prepare and send to LICENSOR a
report setting forth a computation of the Royalty due hereunder and the Gross
Revenue earned through the Licensed Products by LICENSEE and its Affiliates
during such Quarterly Period in each gaming jurisdiction within the Territory
(the "Royalty Report").

         5.3 LICENSEE shall keep accurate records in respect to all revenues
generated from Licensed Products by LICENSEE and its Affiliates and shall
maintain such records for at least 4 years from the date of the Royalty Report.
LICENSOR shall have the right, at its sole cost and expense, not more than once
each year, to have LICENSEE's records reviewed, in respect to revenues earned
from the Licensed Products in the Territory at times which are reasonably
convenient to LICENSEE, using a retained independent certified public accounting
firm. Any Royalty Reports rendered by LICENSEE to LICENSOR prior to the date of
such review as to which LICENSOR raises no reasonable written objection within
ninety (90) days after the commencement of such review shall be deemed
conclusive and binding, provided LICENSEE has not unreasonably impeded such
review. If LICENSOR shall dispute the accuracy of any Royalty Report, the
dispute shall be resolved by a panel of three independent certified public
accountants, one selected by LICENSEE at its sole cost and expense, one selected
by LICENSOR at its sole cost and expense, and the third selected by the
previously selected accountants, the cost and expense of the third panel member
shall be borne equally by LICENSEE and LICENSOR; provided, however that if the
panel of accountants shall determine that the Royalties due hereunder in respect
of Gross Revenue during any Quarterly Period were in excess of 5% of the amount
of Royalties reported by LICENSEE for such Quarterly Period, LICENSEE shall bear
the cost and expense of such panel. The determination of said panel by majority
vote shall be conclusive and binding on the parties hereto.

         5.4 At the termination of this Agreement, LICENSEE shall render a final
Royalty Report to LICENSOR within thirty (30) days after the end of the
Quarterly Period in which such termination occurs.

6        WARRANTY; ENFORCEMENT; INDEMNIFICATION.

Certificate of Incorporation or By-Laws of LICENSOR.

rule or regulation applicable to LICENSOR. LICENSOR is not a party to, or
subject to or bound by, any agreement, judgment, injunction or decree of any
court or governmental authority which may restrict or interfere with the
performance of this Agreement. This Agreement is a valid and binding obligation
of LICENSOR enforceable in accordance with its terms.

ability to perform its obligations under this Agreement.
