Said Paragraphs read, in part, as follows: 12.1 The Principal Investigators will initially supply Licensee with viable samples of the Biological Materials within sixty (60) days from the effective date recited on page one of this Agreement. To the extent Licensee requests and necessarily requires additional samples from the Principal Investigators during the term hereof, and the Principal Investigators have such additional samples in its possession and control, the Principal Investigators will supply such additional samples to the Licensee. Licensee will pay the actual handling and shipping costs for any samples provided. 13.1 Th Regents expressly reserves the right to transfer the Biological Materials to one or more non-profit third parties for educational and non-commercial research purposes only. The Regents will instruct the Principal Investigators that they can transfer the Biological Materials to non-profit third parties solely for educational and non-commercial research purposes under the terms and conditions set forth in the biological material transmission letter attached hereto as Appendix A. The Licensee understands that The Regents' right to transfer the Biological Materials for educational and non-commercial research purposes could lead to the inadvertent loss or diminution of proprietary and commercial value of the Biological Materials. The Biological Material is defined in said Agreement as follows: 1.2 Biological Material" means the following: By: /s/ ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ 3/23/00 Date In May 1989, the University of California issued the Guidelines on University-Industry Relations ("Guidelines"). Guideline 10 entitled "Tangible Research Products" requires that when the commercial availability of tangible research products resulting from the conduct of research is restricted by a license, approval must be obtained from the Chancellor of the campus where the research took place. The Exclusive License and Bailment Agreement ("Agreement") between THE REGENTS OF THE UNIVERSITY OF CALIFORNIA ("The Regents") and Ambryx Inc. ("Licensee") entitled "Nucleic Acids Encoding G-Protein Coupled Receptors and Assays for Identifying Taste Modulators" contains provisions that restrict the transfer of certain tangible research products to the commercial competitors of the Licensee. The provisions of the Agreement require that The Regents will convey tangible research products to others for educational and research purposes under a biological material transfer agreement. In accordance with the Guidelines, this Agreement permits the University to retain the discretion to publish any results of research at any time and to disseminate the tangible materials for educational and research purposes. Chancellor ▇▇▇▇▇▇ ▇. ▇▇▇▇▇ of the University of California, San Diego, approves the provisions of the attached Agreement that restrict the commercial availability of tangible research products.

Notwithstanding any other provisions of the Agreement, the following shall apply: 1. Licensee acknowledges that the grant by The Regents to Licensee pursuant to the Agreement of any interest of the NIH in the Patent Rights shall be subject to the review and approval thereof by the NIH ("NIH Approval"). 2. If NIH Approval shall not have been obtained by the date that is thirty (30) days from the date hereof, then in lieu of any provisions of the Agreement requiring payments by Licensee, Licensee shall [***]. In such event, at such time thereafter as NIH Approval is obtained, Licensee shall pay to The Regents, within ten (10) days of written certification to Licensee thereof by The Regents, all payments that would have been payable by Licensee following the date hereof but which were deferred by the provisions of this paragraph. 3. If NIH Approval is obtained and Licensee has received written certification hereof by The Regents on or prior to the date that is thirty (30) days from the date hereof, then paragraphs 1 and 2 above shall not apply and Licensee shall make all payments required to be made by Licensee in accordance with the terms of the Agreement. 4. Licensee further acknowledges that the grant by The Regents to Licensee pursuant to the Agreement of any interest of The Regents in the Patent Rights shall be subject to the execution by the Chancellor of Appendix C to the Agreement ("The Regents Approval"). 5.
