	B.	Licensee is a wholly-owned subsidiary of Kairos Pharma, Ltd. (“Kairos”).
	C.	CSMC and Kairos are entered into a first Conversion Agreement dated March 7, 2024 (the “First Conversion Agreement”), pursuant to which (i) the parties agreed to convert an aggregate of $750,000 of Licensee’s unpaid fees, costs, and expenses under several license agreements, including this License Agreement, into shares of Common Stock (as defined in the First Conversion Agreement) of Kairos, and (ii) Kairos agreed to pay CSMC the Excess Liabilities, with interest (as previously defined in, and subject to the terms of, the First Conversion Agreement).
	D.	CSMC and Kairos are entering into a Second Conversion Agreement of even date herewith (the “Second Conversion Agreement”), pursuant to which the (i) the parties shall convert an aggregate of $200,000 of Licensee’s unpaid fees, costs, and expenses under several license agreements, including this License Agreement, into shares of Common Stock, and (ii) Kairos shall pay CSMC the Excess Liabilities, with interest (as re-defined in, and subject to the terms of, the Second Conversion Agreement).

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, in the License Agreement, in the Second Conversion Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

1. Defined Terms. Terms not otherwise defined herein shall have the meaning ascribed to them in the License Agreement and Second Conversion Agreement.

2. Amendment to the License Agreement. The parties agree that the Liabilities shall be discharged subject to and conditioned upon (i) the execution, delivery, and performance by Licensee of the Second Conversion Agreement, (ii) the issuance of Conversion Shares under the Second Conversion Agreement to CSIPC, and (iii) Licensee’s payment to CSMC of the Excess Liabilities. The following shall be added to the end of § 4 (Consideration):

In full satisfaction of the Liabilities, and subject to the Second Conversion Agreement, (i) 63.77% of the Conversion Shares issued to Cedars Sinai Intellectual Property Company, a California nonprofit public benefit corporation and wholly-owned subsidiary of CSMC (“CSIPC”), shall be allocated by CSMC to satisfaction of the Liabilities, and (ii) 63.77% of the Excess Liabilities paid to CSMC under the Second Conversion Agreement (including any interest due as set forth therein), shall be allocated by CSMC to satisfaction of the Liabilities. Any material breach by Licensee of the Second Conversion Agreement shall be deemed a breach of the License.

3. Other Provisions. This Amendment is a revision to the License Agreement only; it is not a novation thereof. Except as otherwise provided herein, the terms and conditions of the License Agreement shall remain in full force and effect.

4. Further Assurances. Each of the parties hereto shall execute such further documents and instruments and do all such further acts as may be necessary or required in order to effectuate the intent and accomplish the purposes of this Amendment.
