For the first $1 million of Acquisition Cost 5 % . For the next $1 million 4 % . For the next $1 million 3 % . For the next $1 million 2 % . For all consideration above $4 million 1 % The referral fee shall be paid in the same manner and in the same ratio as that of the transaction e.g. cash, common stock, restricted common stock, etc. If the payment is in cash, then it shall be made within 10 days of the date of Closing. If the payment of the referral fee is in stock, it shall be paid in an expeditious manner contemporaneous with other issuances associated with the transaction and subject to normal SEC reporting and securities issuance procedures.

Wherein the Agreement with the third Party is entered into during or after the term but no later than 18 months after the Term. The referral fee shall be calculated by taking the Company's total gross earnings attributed to the first twelve months of the Term of the new agreement (the "Coventure Revenue") and multiplying that by the following percentage: . For the first $1 million of Co-venture Revenue 5 % . For the next $1 million 4 % . For the next $1 million 3 % . For the next $1 million 2 % . For all Co-venture Revenue above $4 million 1 % The referral fee applies to Co-venture revenue received by the Company during the first 12 months (or received by Company after the first twelve months if earned during the first twelve months) and shall be paid at the close of the twelve-month period or whenever received thereafter. The referral fee shall be paid in the same form of revenue as that received by the Company e.g. cash, common stock, restricted common stock, etc. If the payment is in cash, then it shall be made to the Referrer within 15 days of the Company receiving payment from the alliance / co-venture transaction. If the payment of the referral fee is in stock, it shall be paid in an expeditious manner subject to normal SEC reporting and securities issuance procedures.
