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.

3.5 Failure to Supply Product. In the event that Arch fails to deliver at least [*] of the amount of any particular Product that Arch was obligated to deliver under Section 3.6 ordered pursuant to any particular Product Purchase Order in accordance with the terms of such Product Purchase Order, then, notwithstanding anything to the contrary, Codexis shall have the right to take any and all steps necessary to cover, at the sole cost and expense of Arch, any such shortfall in the supply of such Product and, at Codexis’ sole discretion, to modify any then-outstanding Product Purchase Orders without penalty. Notwithstanding and without limiting the foregoing, Arch acknowledges and agrees that: (a) any failure by Arch to deliver at least [*] of the amount of any particular Product ordered (i) pursuant to three (3) or more Product Purchase Orders in any period of twelve (12) consecutive months or (ii) pursuant to the aggregate of all Product Purchase Orders in any period of twelve (12) consecutive months, in accordance with the terms of such Product Purchase Orders, shall constitute a material breach of this Agreement by Arch with respect to such Product; (b) Codexis shall have the right, but not the obligation, in its sole discretion, to convert its exclusive purchase obligation (and Arch’s exclusive manufacturing right) set forth in Section 2.1 or 4.1, as applicable, with respect to such Product to a non-exclusive arrangement (but, for clarity, in such event, Arch’s supply obligation to Codexis pursuant to Sections 2.1 and/or 4.1, as applicable, shall remain exclusive); and (c) Codexis’ rights pursuant to this Section 3.5 shall not limit any other rights of Codexis under this Agreement with respect to a failure to supply by Arch which constitutes a material breach pursuant to paragraph (a) above, including without limitation, Codexis’ right to terminate this Agreement with respect to such Product pursuant to Section 15.2. The remedies set forth in this Section 3.5 shall be the exclusive remedies of Codexis with respect to Arch’s failure to supply Products.

3.6 Product Purchase Orders. Each of the Product(s) shall be ordered by Codexis by written purchase order submitted electronically (or by any other means agreed by the Parties), in a form to be mutually agreed by the Parties (each, a “Product Purchase Order”). No communications (oral, electronic, written or otherwise) between the Parties in respect of any

purchase or supply of Products shall be binding on the Parties except to the extent such communication is embodied in a Product Purchase Order or other document signed by each Party. In the event that a Codexis Customer modifies or cancels any order for Product, Codexis shall discuss the matter with Arch and only after Arch’s consent in writing (which consent may not be unreasonably withheld or delayed ) modify or cancel a Product Purchase Order provided that Arch has not already shipped Product prior to receipt of the cancellation/modification notice. All Product Purchase Orders shall be deemed accepted by Arch, except with respect to Products subject to a Non-Exclusive Relationship, which Purchase Orders shall be accepted by Arch only if (x) Codexis provides a sufficient quantity of Codexis Enzyme to Arch in order to allow Arch to manufacture the requested quantity of Product in the requested timeframe or (y) accepted in writing by Arch within five (5) days of receipt of such Product Purchase Order. Arch shall promptly provide Codexis written notice in the event that Arch will not be able to deliver any quantities specified in the Product Purchase Order.

3.7 Conflicts. On Product-by-Product basis and Purchase Order-by-Purchase Order basis, in the event a Codexis Customer has additional and/or different terms and conditions regarding the supply of Product or requirement of additional sales documentation, Codexis shall forward such terms and conditions to Arch in writing, either in the applicable Purchase Order or otherwise, and such terms and conditions shall be in addition to the terms and conditions in this Agreement solely for such Purchase Order. To the extent that there is any conflict or any inconsistency between this Agreement and any Product Purchase Order, or any other document pertaining to the supply of Products (except as set forth in Section 3.12.3 ), the terms of this Agreement shall govern. For clarity, no conflicting term or condition added by Codexis to a Product Purchase Order shall be binding on Arch unless such term or condition is specifically agreed to by Arch in writing signed by a duly authorized officer of Arch.

3.8 Delivery of Products. Arch shall deliver to Codexis and/or its designee the amount of each of the Product(s) specified in each Product Purchase Order, together with any other sales documentation or other materials specified in such Purchase Order, no later than the date (or dates) mutually agreed by the Parties therein. All Products shall be (a) delivered to Codexis as inventory supply; or (b) shipped by Arch by air or as otherwise directed by Codexis to the destination designated in writing by Codexis. The Parties shall cooperate in selecting appropriate carriers, and title and risk of loss shall pass to Codexis upon delivery by Arch to such carrier(s). Arch shall notify Codexis in writing within five (5) days after shipping any Product in order to allow Codexis to properly invoice its customers. Arch shall ship each order of Product under appropriate packaging and storage conditions, including, for example, using envirotainers or similar temperature-control equipment for shipments where appropriate. All deliveries will be accompanied by the relevant Certificate of Analysis (CoA), and a detailed delivery note specifying the identity of the material, the quantity and the lot number(s) and any other documents specified in the applicable Product Purchase Order (including, for example, TSE/BSE certificate and Material Safety Data Sheet (MSDS)).

3.9 Inspection of Product. Upon receipt of each shipment of Product, Codexis and/or the Codexis Customer, shall test and inspect such Product for compliance with the Product Specification and other documentation as set forth in Section 3.12 or otherwise provided by Codexis to Arch pursuant to Section 3.7 (as applicable) for such Product corresponding to

such shipment. Codexis and/or the Codexis Customer shall inform Arch of the result of the acceptance inspection including the judgment of acceptance or rejection of all or part of a shipment in writing within ten (10) days (or such other time as may be agreed to by Codexis and a Codexis Customer, as specified in the applicable Product Purchase Order) after the delivery of such shipment of Products. In the event that Arch receives a written notice of rejection from Codexis and/or the Codexis Customer within the timeframes set forth in the following sentence, subject to Section 3.11, Arch shall replace such rejected Product pursuant to Section 3.10. If Codexis and/or the Codexis Customer fails to notify Arch of a rejection within the requisite timeframe, the shipment of Products shall be deemed accepted by Codexis and/or the Codexis Customer. Regardless of any rejection of all or part of a shipment of Product, Codexis shall pay for such Product and if such rejection is determined to be proper by Arch or pursuant to the dispute resolution mechanism set forth in Section 3.11, Codexis shall be entitled to, at its sole discretion, a credit or refund of such properly rejected Product.

3.10 Replacement of Defective Product. In the event that Arch receives a written notice of rejection from Codexis and/or the Codexis Customer, Arch shall, at the sole cost and expense of Arch, replace any shipment of such rejected Product, including without limitation disposal of such Product, within sixty (60) days after receiving Codexis’ and/or the Codexis Customer’s written notice of rejection. For clarity, the foregoing right shall not limit any other remedy available at law or in equity. Codexis and/or the Codexis Customer shall keep such defective Product at the premises of Codexis and/or the Codexis Customer, as applicable, until receipt of Arch’s instruction for Codexis and/or the Codexis Customer to return or otherwise dispose of such defective Product. Notwithstanding anything to the contrary, (i) Arch shall have no obligation to replace any shipment of Product or part thereof pursuant to this Section 3.10 or issue a refund or credit pursuant to Section 3.9 in the event Arch can establish that the Product is not defective or such defect occurred after delivery of Product; and (ii) if the basis for any rejection is a defect due to a change in any regulatory requirement as specified by a Government Authority and which change was not identified by the Government Authority prior to Arch’s manufacture of such Product, then the costs associated with replacement of the defective Product (which costs, for the avoidance of doubt, do not include costs to be borne by Arch in updating its manufacturing processes and procedures to become compliant with any new regulatory requirement or any other costs not attributable directly to the replacement) shall be borne equally by the Parties.

3.11 Disputes. If Arch disputes Codexis’ and/or the Codexis Customer’s right to reject all or part of any shipment of any Product as set forth in Section 3.9, Arch shall notify Codexis within ten (10) days after receipt of Codexis’ and/or the Codexis Customer’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 areas of quality control and quality assurance for active pharmaceutical ingredient and intermediate manufacturing, 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 Product 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 Codexis 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 Codexis.

For the avoidance of doubt, if such Third Party determines that the reasons given by Codexis in rejecting the shipment or part thereof were not proper, then no refund or credit shall be due to Codexis under Section 3.10, 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 3, Arch shall continue delivering Product(s), including without limitation replacement of any defective Products, pursuant to the terms of this Agreement during the dispute resolution process set forth in this Section 3.11.

3.12 Changes and Quality Control.

3.12.1 Specification. As soon as practicable, but in any event no later than thirty (30) days prior to the First Commercial Sale of each Product, Codexis shall provide Arch with the specification for such Product (each, a “Product Specification”), as mutually agreed upon by the Parties. All Product supplied by Arch hereunder shall comply with the applicable Product Specification.

3.12.2 Changes. Arch shall not make any changes or alterations in (i) the Product Specification(s) for any Product or (ii) the process for the manufacture of any Product which change may impact the Product quality (each, a “Change”) without Codexis’ prior written consent.

(a) In the event that Arch requests a Change and Codexis consents to such Change, Arch shall bear the costs associated with implementing such Change, including without limitation any costs incurred in connection with testing such Change by Codexis or any Third Party laboratory designated by Codexis.

(b) In the event that Codexis requests a Change, Codexis shall bear the costs associated with such Change, including without limitation any costs incurred in connection with testing such Change by any Third Party laboratory.

3.12.3 Manufacturing Standards and Procedures. Unless otherwise agreed in writing by Codexis, all Products supplied hereunder and the manufacture thereof shall comply with appropriate quality standards depending on the intended market, including but not limited to cGMP. Arch shall adopt and maintain quality assurance procedures and perform quality control tests designed to ensure that all Products manufactured under this Agreement conform to and are manufactured in accordance with this Agreement, including any other requirements of a Codexis Customer which requirements shall be set forth in the relevant Purchase Order or otherwise set forth in writing by Codexis. Without limiting the foregoing, Arch agrees as follows:

(a) Arch shall be responsible for creating and retaining all records relating to the manufacturing, analysis and distribution, testing and release of materials, production and quality control (including in-process controls) as actual manufacturer, including Product Quality Review, generally in accordance with cGMP and shall provide copies to Codexis upon its reasonable written request.

The Receiving Party shall take the same degree of care that the Receiving Party uses to protect its own confidential and proprietary information of a similar nature and importance, but in no event shall such care be less than reasonable care.

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. The existence of, and the terms and conditions of, this Agreement shall be Confidential Information of each of the Parties, and subject to the terms of this Article 10; provided, however, that (x) each Party may disclose this Agreement, in confidence, (i) to legal, scientific and financial advisors and (ii) in connection with any proposed legal transaction involving the disclosing Party in the form of mergers, offerings, acquisitions, fundings and investments; and (y) each Party may disclose this Agreement, in its entirety or with portions redacted, as may be required by Applicable Law, including but not limited to filing of this Agreement with the Securities and Exchange Commission (and, for the avoidance of doubt, if any such disclosure or filing is made on a non-confidential basis then the portions disclosed or filed shall no longer be deemed Confidential Information).

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.

11. INTELLECTUAL PROPERTY

11.1 Ownership by Codexis.

11.1.1 As between the Parties, subject only to the licenses set forth in Articles 2 or 8, Codexis shall retain all right, title and interest in, to and under the Codexis IP Rights, Codexis Trademarks, Codexis Process, each and every Codexis Enzyme, and Codexis Improvements.

11.1.2 Arch hereby assigns to Codexis all its right, title, and interest in, to, and under any and all discovery, invention, contribution, method, finding, or improvement, whether or not patentable, and all related intellectual property, including without limitation Patents and know-how, that is conceived, reduced to practice, or otherwise developed by Arch or an Affiliate of Arch, either solely or jointly with Codexis and/or a Third Party, during the Term that relates to the Codexis IP Rights, Codexis Trademarks, Codexis Process, any Codexis Enzyme, and/or the Codexis Improvements (collectively, the “Arch Bio-Chemical Improvements”). Arch and its Affiliates agree to cooperate with Codexis, at Codexis’ reasonable request and expense, in the preparation of any patent application claiming any subject matter within such inventions and intellectual property rights.

11.1.3 Codexis, at its own expense, shall have the sole right, but not the obligation, to file applications for and to control the prosecution and maintenance of the Codexis IP Rights and Codexis Trademarks, including without limitation any and all intellectual property assigned by Arch to Codexis pursuant to Section 11.1.2 , except as otherwise expressly noted.

11.2 Ownership by Arch.

11.3 Enforcement.

11.3.1 At any time during the Term, if a Party determines that a Third Party is or may be infringing any Patent, or may have misappropriated any other right, within the Codexis IP Rights, the Party making such determination shall promptly provide written notice to the other Party thereof.

11.3.2 Codexis, at its expense, shall have the right, but not the obligation, to enforce all rights (a) in the Codexis Enzyme(s), Codexis Process(es), and/or Codexis Improvements and any and all intellectual property rights therein, including without limitation the Codexis IP Rights; and (b) with respect to any and all intellectual property assigned by Arch to Codexis pursuant to Section 11.1.2.

11.3.3 In the event that Codexis enforces its rights pursuant to this Section 11.3, Arch and its Affiliates, if applicable, shall cooperate fully with Codexis in such enforcement, including without limitation, by joining as a party plaintiff and executing such documents as Codexis may reasonably request.

11.4 Attorney in Fact. 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.

11.5 Allocation of Recovery. Any recovery awarded by a court of competent jurisdiction or final resort in an unreversed, unappealed, or unappealable decision or judgment from an action by Codexis to enforce any rights within the Codexis IP Rights, including without limitation any and all intellectual property assigned by Arch to Codexis pursuant to Section 11.1.2 , shall be first applied to reimburse Codexis’ and Arch’s unreimbursed expenses on pro-rata basis in proportion to their expenses, including without limitation reasonable attorney’s fees and court costs. 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), Codexis Process(es), and/or Codexis Improvements, 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 payments agreed upon per Section 9.1.2 shall be tripled.

11.7 Third Party Claims. If, after the Effective Date, Arch becomes aware of any claims made by Third Parties that such Third Party’s intellectual property may be infringed by the use, manufacture, having manufactured, marketing, selling, offering to sell, importing, exporting, and/or other distribution of any Products, Arch shall promptly notify Codexis thereof. If, after the Effective Date, Codexis becomes aware of any claims made by Third Parties that such Third Party’s intellectual property rights may be infringed by the use, manufacture, having manufactured, marketing, selling, offering to sell, importing, exporting, and/or other distribution of any Codexis Enzymes or Codexis Process, Codexis shall promptly notify Arch thereof. The Parties shall meet and discuss in good faith steps to avoid any such potential infringement, including without limitation whether to obtain rights to practice under such Third Party-

intellectual property, and, if so, which Party shall obtain such rights and the terms of obtaining such rights and the relative sharing of the costs thereof.

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

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.

Notwithstanding anything to the contrary in Exhibit 13.4.1, each Party shall be required to maintain product liability insurance with at least the following limits: (a) any limit mutually agreed to by the Parties, (b) any limit required by a customer that requests to purchase at least Three Million Dollars ($3,000,000) worth of Products collectively from the Parties and their Affiliates in any one (1) year period, or (c) at the point at which Parties and their Affiliates collectively have sold an aggregate amount of at least Thirty Million Dollars ($30,000,000) worth of Products in any one (1) year period, a combined single limit of not less than Ten Million Dollars ($10,000,000) per occurrence and in the aggregate.

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. In the event that any of the required policies of insurance are written on a claims made basis, then such policies shall be maintained during the entire term of this Agreement and for a period of not less than five (5) years following the termination or expiration of this Agreement.

13.4.3 Each Party shall be named as an additional insured under the other Party’s Commercial General Liability, Products Liability (as applicable) and Umbrella insurance policies to the extent permitted under such policies. Such additional insured status shall end upon the termination or expiration of this Agreement unless the insuring Party’s policies are written on a claims made basis, in which case such additional insured status shall continue for the period of time that such insuring Party is required to maintain such insurance under the terms of this Agreement.

13.4.4 Each Party will (a) furnish certificates of insurance to the other Party evidencing the required insurance and additional insured status, as applicable, prior to the Effective Date and upon request thereafter and (b) provide the other Party with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance that materially adversely affects the rights of the other Party hereunder.

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.

14.2.1 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.

14.2.2 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.

14.2.3 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.

14.2.4 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 the tenth anniversary of the

Effective Date, 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 Process and Codexis Improvements covering the manufacture of such Codexis Enzymes that are used to further manufacture such Product for a one-time lump-sum consideration of [*] per Product (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. In the event Arch exercises its Option, Codexis shall render reasonable support to allow Arch to effectively utilize the rights acquired by the Option exercise, including without limitation, introduction of appropriate contacts and technology support; provided, however, such support shall only be provided during (and only during) scale up at Arch or a contract manufacturing organization designated by Arch and in no event for a period longer than eight (8) weeks. Codexis’ obligations in respect of such support shall be limited to (i) phone and email support and (ii) onsite support limited to ten (10) man-hours per week provided that Arch cover all out-of-pocket travel and boarding expenses. Any license granted to Arch pursuant to this Section 15.5 shall be subject to the following restrictions: (i) Arch may not manufacture any Codexis Enzymes for Third Parties; (ii) Arch may only manufacture Codexis Enzymes solely for use by Arch to manufacture Products for sale by Arch; (iii) Arch may not sublicense any of the rights granted by Codexis to Arch. Furthermore, any license granted to Arch pursuant to this Section 15.5 shall not affect (i) Codexis’ ownership rights in (or Codexis’ rights to grant additional licenses to) Codexis IP Rights, Codexis Process and Codexis Improvements or (ii) Codexis’ right to manufacture Codexis Enzymes that are subject to the product or (iii) Codexis’ right to purchase Products from Third Parties and sell Products to Codexis Customers.
