In consideration of the payment of Two Hundred Fifty Thousand Dollars ($250,000) (the “Assignment Consideration”), Soy Labs hereby sells, assigns, transfers and quit claims to SLTI all right, title and interest in and to the Technology, as defined in the License Agreement. The parties acknowledge and agree that all obligations of SLTI under Sections 2.1(b) and 3 of the License Agreement are hereby terminated and Sections 2.1(b) and 3 of the License Agreement shall be of no further force or effect.

Upon execution of this letter agreement, the parties acknowledge and agree that SLTI shall remit an aggregate payment of Five Hundred Thousand Dollars ($500,000) to Soy Labs representing the Fourth Year Payment (as defined in the License Agreement) currently due under the License Agreement and the Assignment Consideration. Payment shall be made by SLTI to Soy Labs within ten business days of execution of this letter agreement. Upon receipt of the $500,000 payment, SLTI shall have no further monetary obligations to Soy Labs under the License Agreement.

Soy Labs shall execute, acknowledge, and deliver to SLTI all such further instruments and papers, including assignments and powers of attorney, as may be necessary to vest title to the Technology in SLTI, its successors or assigns.
