     3. Compensation of Consultant.

       (a) Royalties. In full consideration of all rights granted herein and all services performed and to be performed hereunder, the Company will pay to Consultant royalties from revenues derived from contracts with customers generated by the Strategic Partner, provided that the Strategic Partner was instrumental in generation of such contracts, subject to the Company’s acceptance of the Strategic Partner and entry into a binding joint venture, strategic alliance or similar agreement of Strategic Partner, as follows.

Gross Receipts shall be deemed to exclude sums received by the Company and/or its affiliates which represent sales taxes, value added taxes, excise taxes, and similar taxes which are collected by the Company and its affiliates as required by any requisite taxing authorities of any government, but limited to the extent that such taxes are paid and not returned or credited to the Company or an affiliate. Gross Receipts shall also be deemed to exclude foreign currencies to the extent any foreign licensing society or organization collects or withholds any portion thereof on behalf of or for the benefit of the Company.
