***Confidential Treatment Requested

made by Ajinomoto herein having been incorrect or misleading in any material respect; (c) any gross negligence or willful misconduct on the part of Ajinomoto or its Affiliates in performing any activity contemplated by this Agreement (for the avoidance of doubt, failure by Ajinomoto to disclose to Senomyx a [***] known to Ajinomoto with respect to a Senomyx [***] Compound or Selected Senomyx [***] Compound, [***], which [***] is a direct and proximate cause of the Loss, would be considered gross negligence); (d) any development, manufacturing, formulation, handling, storage, shipment, sale or other disposition of a Senomyx [***] Compound, Senomyx [***] Compound or a Selected Senomyx [***] Compound by or through Ajinomoto or its Affiliates or its permitted sublicensees; (e) a product liability claim on any [***] Product; (f) a material violation of any contractual or fiduciary duty owed by any Ajinomoto Indemnitee to a Third Party; (g) any alleged or actual misappropriation or infringement of any Third Party’s intellectual property rights by an Ajinomoto Indemnitee; or (h) any alleged or actual misappropriation or infringement of any Third Party intellectual property rights arising out of any use of the Ajinomoto Technology (except for Jointly Owned Technology) or the [***] (except to the extent any Losses arise in connection with the use of [***] by or on behalf of Senomyx).

16.6 Notice of Claim. The indemnified party shall give the indemnifying party prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such indemnified party intends to base a request for indemnification under Section 16.4 or Section 16.5, but in no event shall the indemnifying party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). The indemnified party shall furnish promptly to the indemnifying party copies of all papers and official documents received in respect of any Losses. All indemnification claims in respect of a party, its Affiliates or their respective directors, officers, employees and agents (collectively, the “Indemnitees” and each an “Indemnitee”) shall be made solely by such party to this Agreement (the “Indemnified Party”).

16.7 Control of Defense. At its option, the indemnifying party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within [***] after the indemnifying party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying party shall not be construed as an

***Confidential Treatment Requested

acknowledgment that the indemnifying party is liable to indemnify any Indemnitee in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying party of any defenses it may assert against any Indemnitee’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying party. In the event the indemnifying party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying party all original notices and documents (including without limitation, court papers) received by any Indemnitee in connection with the Third Party Claim. Should the indemnifying party assume the defense of a Third Party Claim, the indemnifying party shall not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the indemnifying party is not obligated to indemnify, defend or hold harmless an Indemnitee from and against the Third Party Claim, the Indemnified Party shall reimburse the indemnifying party for any and all costs and expenses (including without limitation, attorneys’ fees and costs of suit) and any Losses incurred by the indemnifying party in its defense of the Third Party Claim with respect to such Indemnitee.

16.8 Right to Participate in Defense. Without limiting the provisions of Section 16.7, any Indemnitee shall be entitled to participate in, but not control, the defense of such Third Party Claim and to engage counsel of its choice for such purpose; provided, however, that such engagement shall be at the Indemnitee’s own expense unless (a) the engagement thereof has been specifically authorized by the indemnifying party in writing, (b) the indemnifying party has failed to assume the defense and engage counsel in accordance with Section 16.7 (in which case the Indemnified Party shall control the defense), or (c) in the Indemnitee’s reasonable judgment, a material conflict of interest between the Indemnitee and the indemnifying party exists in respect of such Third Party Claim, provided that, in any event, the other provisions of this Section 16.8 shall continue to apply to such Third Party Claim.

16.9 Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the indemnifying party shall have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the indemnifying party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the

indemnifying party has assumed the defense of the Third Party Claim in accordance with Section 16.7, the indemnifying party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The indemnifying party shall not be liable for any settlement or other disposition of a Loss by an Indemnitee that is reached without the written consent of the indemnifying party. Regardless of whether the indemnifying party chooses to defend or prosecute any Third Party Claim, no Indemnitee shall admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying party, except in the event the Indemnified Party has assumed control of the defense of such Third Party Claim pursuant to Section 16.8(b).

16.10 Cooperation. Regardless of whether the indemnifying party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall, and shall cause each other Indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the indemnifying party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

16.11 Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including without limitation, fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim shall be reimbursed on a calendar quarter basis by the indemnifying party, without prejudice to the indemnifying party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying party is ultimately held not to be obligated to indemnify the Indemnified Party.

17. Miscellaneous.

17.1 Force Majeure. Neither party shall be held liable or responsible to the other party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing party, including without limitation, fires, floods, earthquakes, hurricanes, typhoons, landslides, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not) or

terrorism, insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority. The non-performing party shall notify the other party of such force majeure within [***] after such occurrence by giving written notice to the other party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing party shall use commercially reasonable efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for [***] after the date of the occurrence, the parties shall meet to discuss in good faith how to proceed in order to accomplish the purposes of this Agreement.

17.2 Governing Law and Jurisdiction. This Agreement will be governed by the laws of [***], as such laws are applied to contracts entered into and to be performed entirely within such state.

17.3 Binding Effect. This Agreement will be binding upon and inure to the benefit of the successors and permitted assigns of the parties. Any assignment not in accordance with this Agreement will be void.

17.4 Dispute Resolution.

(A) Negotiation. The parties recognize that disputes or controversies as to certain matters may from time to time arise during the Term, which relate to either party’s rights and/or obligations hereunder (“Disputes”). It is the objective of the parties to establish procedures to facilitate the resolution of Disputes arising under this Agreement in an expedient manner by mutual cooperation and negotiation. The parties agree that prior to any arbitration concerning this Agreement, Senomyx’s duly authorized representative and Ajinomoto’s duly authorized representative will meet in person or by video-conferencing in a good faith effort to resolve any disputes concerning this Agreement. Within [***] of a formal request by either party to the other party, either party may, by written notice to the other party, have such dispute referred to their respective officers designated or their successors, for attempted resolution by good faith negotiations, such good faith negotiations to begin within [***] after such notice is received.

(B) Arbitration. Any Dispute arising out of or relating to any provision of or in connection with this Agreement or the interpretation, enforceability, performance, breach, termination or validity hereof, including, without limitation, this arbitration clause, shall be solely and finally settled by binding arbitration pursuant to [***]. Any such arbitration shall be held in [***]

***Confidential Treatment Requested

[***]. There shall be [***] and [***]. In such latter case, each party shall name [***]. Within [***] following appointment of the arbitrator or arbitrators, if there are to be [***] arbitrators, the arbitrator(s) will hold a conference with the parties to the arbitration to establish a schedule pursuant to which an award will be rendered within [***] of such conference. Each party hereto shall bear its own costs and expenses, but the compensation and costs and expenses of the arbitrators shall be borne equally between the parties participating in the arbitration. The English language shall be used in any and all arbitral proceedings and all documents, exhibits and other evidence shall be translated into the English language.
