Notwithstanding anything to the contrary, Codexis shall have no obligation to replace any shipment of Codexis Enzyme or part thereof pursuant to this Section 2.12 or issue a refund or credit pursuant to Section 2.11 in the event Codexis can establish that there was

no defect or such defect occurred after delivery of such shipment of Codexis Enzyme. Codexis shall in good faith provide details to Arch of test methods that are customarily employed by Codexis to check the purity and quality of Codexis Enzyme supplied to Arch. In the case of a marginal Enzyme Specification failure or non-compliance, the relevant Codexis Enzyme can be offered to Arch for use at a higher loading rate in the production process than dictated by the standard recipe. Under such cases, if there is increased inconvenience to Arch in use of such Codexis Enzyme then a reduced price will be agreed to by the Parties that reflects the increased usage and inconvenience.

2.13 Disputes. If Codexis disputes Arch’s right to reject all or part of any shipment of any Codexis Enzyme as set forth in Section 2.11, Codexis shall notify Arch within ten (10) days after receipt of Arch’s written notice of such rejection. Such dispute shall be resolved by a Third Party within thirty (30) days of such notice. Such Third Party shall have expertise in the area of biocatalysis, the identity of whom shall be mutually agreed upon by the Parties, and the appointment of whom shall not be unreasonably delayed or conditioned by either Party. The determination of such Third Party with respect to all or part of any shipment of any Codexis Enzyme shall be final and binding upon the Parties. The Third Party’s scope of review and decision shall be strictly limited to the reasons given by Arch in rejecting the shipment or part thereof, and such Third Party may not consider any alleged defects or reasons beyond the alleged defects and reasons given by Arch. For the avoidance of doubt, if such Third Party determines that the reasons given by Arch in rejecting the shipment or part thereof were not proper, then no refund or credit shall be due to Arch under Section 2.11, even if such Third Party determines that the shipment was defective on other, independent bases. The fees and expenses of such Third Party shall be paid by the Party against which the determination is made. Notwithstanding anything to the contrary in this Article 2, Codexis shall continue delivering Codexis Enzyme(s) pursuant to the terms of this Agreement and Arch shall pay for Codexis Enzymes, including without limitation replacement of any defective Codexis Enzyme, pursuant to the terms of this Agreement during the dispute resolution process set forth in this Section 2.13.

10.3 Exceptions. The obligations of non-disclosure and non-use under Section 10.2 will not apply as to particular Confidential Information of a Disclosing Party to the extent that such Confidential Information: (a) is at the time of receipt, or thereafter becomes, through no fault of the Receiving Party or its Affiliates, published or publicly known or available; (b) is known by the Receiving Party or its Affiliates at the time of receiving such information, as evidenced by competent written records; (c) is hereafter furnished to the Receiving Party or its Affiliates by a Third Party without breach of a duty to the Disclosing Party; or (d) is independently discovered or developed by the Receiving Party or its Affiliates without use of, application of, access to, or reference to Confidential Information of the Disclosing Party, as evidenced by competent written records.

10.4 Disclosure Required by Law. Disclosure of Confidential Information shall not be precluded if such disclosure (a) is in response to a valid order, or required under the regulations, of

a court or other governmental body; or (b) is required by Applicable Law; provided, however, that the Receiving Party first has given reasonable prior notice to the Disclosing Party and at the Disclosing Party’s request, the Receiving Party cooperates with the Disclosing Party’s efforts, as applicable, to obtain a protective order limiting the extent of such disclosure and requiring that the Confidential Information so disclosed be used only for the purposes for which such order was issued or as required by such Applicable Law.

10.5 Remedies. The Receiving Party agrees that its obligations under this Article 10 are necessary and reasonable to protect the Disclosing Party’s business interests and that the unauthorized disclosure or use of Confidential Information of the Disclosing Party will cause irreparable harm and significant injury, the degree of which may be difficult to ascertain. The Receiving Party further acknowledges and agrees that in the event of any actual or threatened breach of this Article 10, the Disclosing Party may have no adequate remedy at law and, accordingly, that the Disclosing Party will have the right to seek an immediate injunction, without an obligation to post a bond or any similar security, enjoining any breach or threatened breach of this Article 10, as well as the right to pursue any and all other rights and remedies available at law or in equity for such breach or threatened breach.

10.6 Agreement Terms.

10.7 Survival. All obligations of non-disclosure and non-use imposed pursuant to the terms and conditions of this Article 10 shall survive expiration or termination of this Agreement and continue in full force and effect for a period of ten (10) years after the effective date of such expiration or such termination.

If Codexis cannot obtain the signature of Arch or its Affiliates, as applicable, on any document necessary to exercise its rights under this Article 11, Arch and each of its Affiliates hereby irrevocably designates and appoints Codexis and each of its duly authorized officers and agents as Arch’s agent and attorney-in-fact, to act for, and on behalf of Arch, to execute and file any such document to further exercise Codexis’ rights or protections with the same force and effect as if executed and delivered by Arch or its Affiliates. Exercise of the foregoing right shall be at the sole expense of Codexis, and Codexis agrees to hold Arch and each of its Affiliates

harmless against any loss, liability, or expense that Arch may have to incur on account of the exercise by Codexis of such right. This Section 11.4 shall not apply with respect to the execution and/or filing of any document in the event of any dispute between the Parties with respect to the ownership provision under Section 11.1.2. If any document is executed and/or filed by Codexis on behalf of Arch prior to any dispute between the two Parties on any matter contained in Section 11.1, such document shall not bind Arch in any manner. On each occasion of exercise of the right conferred in the first sentence of this Section 11.4, Codexis agrees to provide a written notice to Arch within seven (7) days after such exercise, containing material particulars of the document filed and/or executed.

Any remaining amount of such damages or other monetary awards shall then be applied between the Parties in such action or proceeding on a pro rata basis based upon the Parties’ respective out-of-pocket expenses directly associated with such action or proceeding.

11.6 Termination for Patent Challenge. If Arch or any of its Affiliates challenges in a court of competent jurisdiction or in any interference, re-examination or opposition proceeding, the validity, scope or enforceability of any Patent embodied in the Codexis Enzyme(s) and/or Codexis Process(es, including without limitation the Codexis IP Rights, Codexis shall have the right to terminate this Agreement immediately upon written notice to Arch provided in accordance with Section 16.7. If Applicable Law prevents Codexis from termination of this Agreement pursuant to this Section 11.6, Arch acknowledges and agrees that Arch may retain the licenses granted under this Agreement; provided, however, that the relationship between the Parties in respect of all Products shall convert to a Non-Exclusive Relationship.

13.2 Codexis Indemnification. Codexis shall indemnify, defend, and hold Arch, and its directors, officers, employees, agents, and Affiliates, harmless from and against all Third Party claims, demands, damages, liabilities, losses, costs, and expenses, including without limitation attorney’s fees (each, a “Claim”) resulting from or arising out of (a) any breach by Codexis of any of Codexis’ representations, warranties, or covenants under Article 12; or (b) the development, testing, manufacture, use, sale, offer for sale, importation, exportation, storage, handling, transportation, distribution, or any other disposition of any Codexis Enzyme (while under the exclusive custody or control of Codexis or any Affiliate of Codexis) by Codexis or any Affiliate of Codexis; provided, however, that Codexis’ indemnification obligations under this Section 13.2 shall not apply (i) to any such Claim arising out of Arch’s negligence or willful misconduct; (ii) to the extent such Claim is the responsibility of Arch under Section 13.1; or (iii) to the extent that Codexis has complied with all Applicable Laws and its rights and obligations under this Agreement.

13.3 Procedure. For purposes of this Article 13, the indemnified Party shall give prompt written notice in accordance with Section 16.7 to the indemnifying Party of any suits, claims, or demands by Third Parties or the indemnified Party that may give rise to any Claim for which indemnification may be required under this Article 13; provided, however, that failure to give such notice shall not relieve the indemnifying Party of its obligation to provide indemnification hereunder except if and to the extent that such failure materially affects the ability of the indemnifying Party to defend the applicable suit, claim, or demand.

13.4.2 Such insurance shall insure against all liability arising out of the manufacture, use, sale, distribution, or marketing of Products. The insurance will contain no more than an ordinary deductible. Such insurance shall be primary, without regard to any other insurance the insured Party or any other additional insured shall maintain or otherwise have in force. The Parties acknowledge and agree that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Section 13.4.

14. DISPUTE RESOLUTION

14.1 Exclusive Dispute Resolution Mechanism. The Parties agree that the procedures set forth in this Article 14 shall be the exclusive mechanism for resolving any disputes, controversies, or claims (collectively, “Disputes”) between the Parties that may arise from time

to time pursuant to this Agreement relating to either Party’s rights and/or obligations hereunder that cannot be resolved through good faith negotiation between the Parties.

14.2 Arbitration.

14.2.8 Any and all unresolved Disputes, except as set forth in Section 14.3 or Section 14.4, shall be exclusively and finally resolved by binding arbitration.

14.2.9 Any arbitration concerning a Dispute shall be conducted in London, unless otherwise agreed to by the Parties in writing. Each and any arbitration shall be administered by the London Court of International Arbitration (“LCIA”), and shall be conducted in accordance with LCIA Rules (the “Rules”), as such Rules may be amended from time to time. All arbitration proceedings will be conducted in the English language.

14.2.10 Within ten (10) days after receipt of an arbitration notice from a Party, the Parties shall attempt in good faith to agree on a single neutral arbitrator with relevant industry experience to conduct the arbitration. If the Parties do not agree on a single neutral arbitrator within ten (10) days after receipt of an arbitration notice, each Party shall select one (1) arbitrator within fifteen (15) days after receipt of an arbitration notice and the two (2) Party-selected arbitrators shall select a third arbitrator with relevant industry experience to constitute a panel of three (3) arbitrators to conduct the arbitration in accordance with the Rules. In the event that the two (2) Party-selected arbitrators are unable to select the third arbitrator due to lack of mutual consent, the Parties shall request the LCIA to appoint an independent and qualified third arbitrator and an appointment made by LCIA pursuant to such request shall be binding on both the Parties. In the event that only one of the Parties selects an arbitrator within fifteen (15) days after receipt of an arbitration notice, then such arbitrator shall be entitled to act as the sole arbitrator to resolve the Dispute or any and all unresolved issues subject to the arbitration. Each and every arbitrator of the arbitration panel conducting the arbitration must and shall agree to render an opinion within twenty (20) days after the final hearing before the panel.

14.2.11 The decision or award of the arbitrator(s) shall be final, binding, and incontestable and may be used as a basis for judgment thereon in any jurisdiction. To the full extent permissible under Applicable Law, the Parties hereby expressly agree to waive the right to appeal from the decision of the arbitrator(s), there shall be no appeal to any court or other authority (government or private) from the decision of the arbitrator(s), and the Parties shall not dispute nor question the validity of such decision or award before any regulatory or other authority in any jurisdiction where enforcement action is taken by the Party in whose favor the decision or award is rendered, except in the case of fraud. The arbitrator(s) shall, upon the request of either Party, issue a written opinion of the findings of fact and conclusions of law and shall deliver a copy to each of the Parties. Each Party shall bear its own costs and attorney’s fees, and the Parties shall equally bear the fees, costs, and expenses of the arbitrator(s) and the arbitration proceedings; provided, however, that the arbitrator(s) may exercise discretion to award costs, including attorney’s fees, to the prevailing Party. Without limiting any other remedies that may be available under Applicable Law, the arbitrator(s) shall have no authority to award provisional remedies of any nature whatsoever, or punitive, special, consequential, or any other similar form of damages except as expressly set forth in Section 16.2.

14.3 Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, and pursuant to Section 10.5, a Party may seek a temporary restraining order or a preliminary injunction from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the decision of the arbitrator(s) on the ultimate merits of any Dispute.

14.4 Patent Disputes. Notwithstanding anything in this Agreement to the contrary, any and all issues regarding the scope, construction, validity, and enforceability of one or more Patents shall be determined in a court of competent jurisdiction under the local patent laws of the jurisdictions having issued the Patent or Patents in question.

14.5 Confidentiality. All proceedings and decisions of the arbitrator(s) shall be deemed Confidential Information of each of the Parties, and shall be subject to the terms and conditions of Article 10.

15. TERM, TERMINATION and BUY-OUT RIGHT

15.1 Term. The term of this Agreement shall commence on the Effective Date and continue in full force and effect on a Product-by-Product basis until February 16, 2020, unless extended by mutual agreement of the Parties and/or unless terminated at an earlier date in accordance with Sections 15.2 or 15.3 (the “Term”).

15.2 Termination for Cause. If a Party breaches any material term or condition of this Agreement, the other Party may notify the breaching Party in writing of such breach, in accordance with Section 16.7, setting forth the nature of the breach in reasonable detail. If the breaching Party fails to cure such breach (if curable) within thirty (30) days after the receipt of the foregoing notice from the non-breaching Party, the non-breaching Party may terminate this Agreement effective immediately upon delivery of a second written notice to the breaching Party. Any breach by an Affiliate of Arch of any of the terms and conditions of this Agreement shall constitute a breach of this Agreement by Arch. In the event of a non-curable breach, the non-breaching Party shall be entitled, in the non-breaching Party’s sole discretion, to immediately terminate on a Product-by-Product basis or this Agreement in its entirety.

15.3 Termination for Insolvency. To the extent permitted under Applicable Law, a Party may terminate this Agreement upon thirty (30) days written notice to the other Party on or after the occurrence of any of the following events: (a) the appointment of a trustee, receiver or custodian for all or substantially all of the property of the other Party, or for any lesser portion of such property, if the result materially and adversely affects the ability of the other Party to fulfill its obligations hereunder, which appointment is not dismissed within sixty (60) days; (b) the determination by a court or tribunal of competent jurisdiction that the other Party is insolvent such that a Party’s liabilities exceed the fair market value of its assets; (c) the filing of a petition for relief in bankruptcy by the other Party on its own behalf, or the filing of any such petition against the other Party if the proceeding is not dismissed or withdrawn within sixty (60) days thereafter; (d) an assignment by the other Party for the benefit of creditors; or (e) the dissolution or liquidation of the other Party.

15.4 Effect of Expiration or Termination.

15.4.1 Upon expiration of this Agreement, on a Product-by-Product basis, pursuant to Section 15.1 (but not early termination), the licenses in respect of such Product under Section 2.2 shall terminate unless Arch exercises the right provided in Section 15.5 of this Agreement.

15.4.2 Upon expiration or termination of this Agreement by either Party for any reason, each Party shall promptly return, or destroy and provide written certification of such destruction by a duly authorized officer of such Party, any and all Confidential Information of the other Party in such first Party’s possession or control at the time of such expiration or termination, provided however, if Arch is entitled to exercise its right under Section 15.5 and exercised such right, then Arch shall not be required to return or destroy any Confidential Information in Arch’s possession at the time of such expiration or termination which Confidential Information is used to practice or exploit any right acquired by the exercise of the Option pursuant to Section 15.5 below.

15.4.3 Expiration or termination of this Agreement for any reason shall not (a) release any Party from any obligation that has accrued prior to the effective date of such expiration or termination (including the obligation to pay amounts accrued and due under this Agreement prior to the expiration or termination date but which are unpaid or become payable thereafter), (b) preclude any Party from claiming any other damages, compensation, or relief that it may be entitled to upon such expiration or termination, or (c) terminate any right to obtain performance of any obligation provided for in this Agreement that shall survive expiration or termination.

15.5 Right to acquire Product license on the occurrence of any Buy-Out Event. On the occurrence of any Buy-Out Event, Arch shall have the right, but not the obligation, to acquire an irrevocable, royalty-free, perpetual and non-exclusive license on a Product-by-Product basis, to Codexis IP Rights, Codexis Enzymes and Codexis Process covering the manufacture of such Codexis Enzymes that are used to further manufacture such Product for a one-time lump-sum consideration of [***] (the “Option”). The Option shall expire in ninety (90) days from the day of occurrence of the Buy-Out Event unless Arch exercises its Option and makes the payment of the said consideration to Codexis within such ninety (90) day period. During such ninety (90) day period, if the Buy-Out Event is other than bankruptcy or insolvency of Codexis or expiration of this Agreement, Codexis shall continue to perform its obligations under the Agreement in respect of the Products not subject to the Buy-Out Event. The payment above shall be Codexis’ sole compensation for such Option-exercise by Arch.
