              APPENDIX 4: ADDITIONAL PRODUCTS PROVIDED TO SLS BY BG


         BG will provide to SLS the following products on the terms and
conditions listed. "Exclusive" shall mean that SLS will be the only customer for
these products, "Non Exclusive" means that BG will sell to SLS and it's own
customers, but will not sell OEM versions to any customer except SLS:

o    BG's line array, tentatively called the Model LS6593, consisting of a

                 APPENDIX 5 MINIMUM PURCHASE REQUIREMENTS BY SLS

         Concurrent with the signing of this addendum SLS has provided BG with a
Purchase Order for 250 units of the LS6593 (the "Initial Purchase Order"), with
additional purchase orders for 250 units in 90 days. The price per unit provided
to SLS in the additional purchase orders shall be the same price per unit
provided to SLS in the Initial Purchase Order. In consideration of the payment
of $100,000 from SLS to BG pursuant to this Addendum, SLS will be allowed a
discount against the products purchased pursuant to such purchase orders in an
amount equal to 100% of the purchase price of each unit until such time as the
aggregate discounts received equals $100,000.

         In the event that SLS's product needs change, BG and SLS agree to
negotiate a recalculation and/or redistribution of the discount allowed above,
including reassignment to other products on a substantially similar basis.
