(formerly named NantBioScience, Inc.), a Delaware corporation (the “Purchaser”). Certain capitalized terms used in this Agreement without definition shall be construed to have the meanings set forth or referenced in Section 1.3.

WHEREAS, the Company has borrowed an aggregate of $98,029,281.92 from the Purchaser pursuant to a Demand Promissory Note dated January 31, 2016 (the “Promissory Note”);

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:
