As Merck is responsible for the payment of [***] Payments due under Section 7.4 and for submitting payment reports and purchase orders pursuant to Section 7.5 for Merck Developed API(s) manufactured by or for permitted Third Party licensees, successors, assignees and transferees, Merck shall be responsible for collecting from permitted Third Party licensees, successors, assignees and transferees and maintaining for the periods set forth in this Section 8.1 all books and records that are reasonably necessary for Merck to demonstrate compliance with Sections 7.4 and 7.5.

8.2 Audit Rights.

8.2.1 Upon the written request of Codexis and not more than [***] in each Calendar Year, Merck shall permit Codexis, through its authorized representatives (as described in Section 8.2.2) to audit Merck’s and its Affiliates’ compliance with Article 3, Section 7.4, Section 7.7 and/or to verify the accuracy of payment reports (and supporting documentation) and purchase orders submitted by Merck pursuant to Section 7.5. For the avoidance of doubt, Codexis’ exercise of its audit rights set forth above shall be limited to [***], whether it exercises its rights to audit all or any part of the areas of compliance which are subject to audit. Once an audit is complete (including any extensions of the audit to allow for investigation of issues revealed by the audit), Codexis shall [***].

8.2.2 All such audit(s) shall be conducted by an independent certified public accounting firm [***] selected by Codexis and reasonably acceptable to Merck (using, as appropriate, reputable subject matter experts for non-financial matters) and at Codexis’ expense (subject to Section 8.2.6 below). All such audits shall be conducted during normal business hours and upon reasonable advance notice and shall be limited to the books and records of Merck and its Affiliates reasonably related to the area of inquiry. Codexis shall treat all such records subject to review under this Section 8.2.2 in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm (and associated experts) to enter into an acceptable confidentiality agreement with Merck obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

8.2.3 All such audit(s) shall be limited to the applicable time periods specified in Section 8.1.

8.2.4 To the extent the audit is directed at Merck’s and/or its Affiliates’ compliance with Section 7.4, results of such investigation shall be made available to both Merck and Codexis; provided that such designee shall disclose to Codexis only its determination of whether the product constitutes a Fee Bearing Therapeutic Product and shall disclose no other information revealed in such investigation to Codexis. Any materials examined by such designee shall be deemed Merck’s Information, which may not be disclosed by such designee to any Third Party. If, as a result of any such

- 34 –

Execution Version

investigation, such designee determines that such product constitutes a Fee Bearing Therapeutic Product, then Merck shall (a) make all payments required to be made to Codexis under Section 7.4 with respect to such Fee Bearing Therapeutic Product that occurred prior to the date the Parties received such results within [***] after the date the Parties received such results, and shall be responsible for any such payments with respect to such Fee Bearing Therapeutic Product thereafter and (b) pay interest on all late payments in accordance with Section 7.9.

8.2.5 To the extent the audit is directed at Merck’s and/or its Affiliates’ compliance with Section 7.5, the report of the independent certified public accounting firm shall be shared with Merck prior to distribution to Codexis such that Merck can provide the independent, certified public accounting firm with justifying remarks for inclusion in the report prior to sharing the conclusions of such report with Codexis. Results of any such examination shall be made available to both Merck and Codexis. The independent, certified public accounting firm shall disclose to Codexis only the amounts that the independent, certified public accounting firm believes to be due and payable hereunder to Codexis and details concerning any discrepancy from the amount paid and the amount due, and shall disclose no other information revealed in such audit. Any and all records examined by such independent, certified public accounting firm shall be deemed Merck’s Information, which may not be disclosed by said independent, certified public accounting firm to any Third Party. If, as a result of any inspection of the books and records of Merck, it is shown that payments under this Agreement were less than the amount that should have been paid, then Merck shall (i) make all payments required to be made to Codexis to eliminate any discrepancy revealed by such inspection within [***] and (ii) pay interest on all late payments in accordance with Section 7.9. In the event that the audit demonstrates a net overpayment by Merck, Merck shall withhold such overpayment from future [***] Payments.

8.2.6 Codexis shall pay for such audits, except that in the event that the audited amounts reveal an underpayment, or complete failure to pay with respect to a Merck Developed API for which Agreement Payments are payable, by Merck [***] of the undisputed amounts that should have been paid during the period in question as per the audit, Merck shall pay Codexis’ out-of-pocket costs of the audit (including the fees and expenses of the independent, certified public accounting firm).

Execution Version

10.1.2 is in the public domain by use and/or publication before its receipt from the disclosing Party, or thereafter enters the public domain through no fault of the receiving Party;

10.1.3 is subsequently disclosed to the receiving Party by a Third Party who may lawfully do so and is not under an obligation of confidentiality to the disclosing Party; or

10.1.4 is developed by the receiving Party independently of Information received from the disclosing Party, as documented by the receiving Party’s business records.

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the receiving Party.

10.2 Authorized Disclosure. The receiving Party may disclose Information belonging to the disclosing Party, and Information deemed to belong to both Parties under the terms of this Agreement, to the extent and only to extent) such disclosure is reasonably necessary in the following instances the receiving Party may disclose Information belonging to the disclosing Party, and Information deemed to belong to both Parties under the terms of this Agreement, to the extent and only to extent) such disclosure is reasonably necessary in the following instances:

If and whenever any Information is disclosed in accordance with this Section 10.2, such disclosure shall not cause any such Information to cease to be confidential, except to the extent that such disclosure

No such notice shall be required under this Section 10.4 if the description of or reference to this Agreement contained in the proposed filing has been included in any previous filing made by either Party hereunder or otherwise approved by the other Party.

10.5 Publicity/Use of Names.

[***].

11.1.3 Codexis’ indemnification obligations under Section 11.1.2 will be limited as follows: [***].

11.2 Merck Indemnity. Merck shall indemnify, defend, and hold harmless Codexis and its Affiliates, and their respective officers, directors, employees, agents, licensors, and their respective successors, heirs and assigns, and representatives (the “Codexis Indemnitees”), from and against any and all Losses from Claims from Third Party(ies) to the extent arising out of or relating to, directly or indirectly: (a) the negligence, recklessness or wrongful intentional acts or omissions of Merck, its Affiliates, and sublicensees and its or their respective directors, officers, employees and agents, in connection with Merck’s performance of its obligations or exercise of its rights under this Agreement; (b) any breach by Merck of any representation, warranty or covenant set forth in this Agreement; (c) research, development, synthesis, transfer, handling, storage, sale, use, optimization, modification, isolation, engineering, identification, selection, making, having made, importation, exportation or other disposition of any Merck Developed API or Therapeutic Product by or on behalf of Merck or any of its Affiliates, sublicensees, agents and contractors (other than Codexis) , including for each of clauses (a), (b), and (c) above, claims and threatened claims based on (i) product liability, bodily injury, risk of bodily injury, death or property damage or (ii) the failure to comply with Applicable Law; provided, however, that Merck’s indemnification obligations under this Section 11.2 will not apply to any such Losses to the extent (A) such Losses are finally determined by a court or tribunal of competent jurisdiction to be attributable to any Codexis Indemnitee having committed an act or acts of negligence, recklessness or willful misconduct, (B) such Losses result from any breach by Codexis of any representation, warranty or covenant set forth in this Agreement, or (C) Codexis is required to indemnify Merck pursuant to Section 11.1.

- 44 –

Execution Version

failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Agreement, except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice). The Indemnitor shall have the right to assume and control the defense of the Indemnification Claim at its own expense with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflicting interests between such Indemnitee and the Indemnitor; provided that the Indemnitor shall not be obligated to pay the fees of more than one counsel retained by all Indemnitees. If the Indemnitor does not assume the defense of the Indemnification Claim as described in this Section 11.3 above, the Indemnitee may defend the Indemnification Claim, but shall have no obligation to do so. The Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, and the Indemnitor shall not settle or compromise the Indemnification Claim in any manner which would have an adverse effect on the Indemnitee’s interests (including any rights under this Agreement), without the prior written consent of the Indemnitee, which consent, in each case, shall not be unreasonably withheld or delayed. The Indemnitee shall reasonably cooperate with the Indemnitor at the Indemnitor’s reasonable expense and shall make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information shall be subject to Article 10.

11.4 Insurance. Each Party shall maintain at all times during the Term commercial general liability insurance and product liability insurance in respect of any Claim from a Third Party, as contemplated in Section 11.1.1 and Section 11.2, from a recognized, creditworthy insurance company, with coverage limits of at least [***] per such Claim from such Third Party. With respect to Merck, such product liability insurance shall include coverage for any Claims from Third Party(ies) subject to Section 11.2 in respect of any Merck Developed API or Therapeutic Product undergoing clinical trials. The minimum level of insurance set forth herein shall not be construed to create a limit on either Party’s liability hereunder. Within ten (10) days following reasonable written request from either Party, the other Party shall furnish to the requesting Party a certificate of insurance evidencing such coverage. In the case of a material modification or cancellation of such coverage, each Party shall notify the other Party as soon as reasonably practicable and provide the other Party with a new certificate of insurance evidencing that such Party’s coverage meets the requirements of this Section 11.4. Notwithstanding the aforementioned, each Party may elect to self-insure or re-insure all of parts of the limits described above and, in such event, this Section 11.4 shall apply to such self-insurance or re-insurance arrangements mutatis mutandis.

- 45 –

Execution Version

Agreement, in its entirety, in the Non-Breaching Party’s sole discretion in the event the other Party (the “Breaching Party”) has materially breached this Agreement, and such material breach has continued for sixty (60) days (the “Cure Period”) after written notice thereof is provided to the Breaching Party by the Non-Breaching Party, such notice describing the alleged material breach in sufficient detail to put the Breaching Party on notice. If at the end of the Cure Period, the Breaching Party can demonstrate that it is actively seeking to remedy such material breach, then at the Breaching Party’s request and with the consent of the Non-Breaching Party (not to be unreasonably withheld), the Non-Breaching Party shall grant an additional forty-five (45) days for the Breaching Party to remedy such breach.

12.3 Insolvency or Bankruptcy. To the extent permitted under Applicable Law, either Party may terminate this Agreement, (a) if, at any time, the other Party files in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially all of its assets, or (b) if the other Party is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within ninety (90) days after the filing thereof, or (c) if the other Party shall propose or be a party to any dissolution or liquidation, or (d) if the other Party shall make an assignment of substantially all of its assets for the benefit of creditors. Each Party agrees to give the other Party prompt notice of the foregoing events giving rise to termination under this Section 12.3. All rights and licenses granted under or pursuant to any section of this Agreement are and shall otherwise be deemed to be for purposes of Section 365(n) of Title 11, United States Code (the “Bankruptcy Code”) licenses of rights to “intellectual property” as defined in Section 101(35A) of the Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code. All materials required to be delivered by the non-bankrupt Party under this Agreement (including all manufacturing information) shall be considered to be “embodiments” of such intellectual property for purposes of Section 365(n) of the Bankruptcy Code. Upon the bankruptcy of any Party, the non-bankrupt Party shall further be entitled to a complete duplicate of, or complete access to, any intellectual property licensed to the non-bankrupt Party, and such, if not already in its possession, shall be promptly delivered to the non-bankrupt Party, unless the bankrupt Party elects to continue, and continues, to perform all of its obligations under this Agreement. All written agreements entered into in connection with the Parties’ performance under this Agreement from time to time shall be considered agreements “supplementary” to this Agreement for purposes of Section 365(n) of the Bankruptcy Code.

12.4 Merck Termination at Will. At any time after Wave 1 (and receipt by Codexis of the Milestone Payment associated with the Completion of Wave 1 as contemplated by Section 7.3), Merck may terminate this Agreement in its entirety at any time upon providing ninety (90) days’ written notice to Codexis at any time and for any reason or for no reason at all. In such event, Merck shall pay to Codexis all reasonable non-cancellable and non-terminable costs incurred by Codexis upon such event of termination. If Merck terminates this Agreement pursuant to this Section 12.4 prior to receipt by Codexis of the Milestone Payment associated with the Completion of Wave 2 as contemplated by Section 7.3, in addition to the provisions of Section 12.6.2, Merck shall pay to Codexis the applicable termination payment set forth in this Section 12.4.

12.6.3 Codexis Audit Right on Merck Breach; Termination; Divestment. In the event of termination of this Agreement by Codexis pursuant to Section 12.2, 12.3 or 12.5, or by Merck pursuant to Section 12.4, or if Merck sells, leases, loans, provides or otherwise divests to any Third Party any facility or business unit that practices or otherwise uses any Codexis Core Technology, Codexis Core Technology Improvements or other Technology related to Covered Enzymes or Enzymes, Merck shall provide to Codexis, within ninety (90) days after the effective date of such termination, or within ninety (90) days after the effective date of such divestment, as applicable, a certification signed by a duly authorized executive or non-executive officer of Merck, certifying that all Codexis proprietary materials, information, and technology in custody or control of Merck or sublicensee of Merck, or at the divested facility or business unit, has been destroyed (including, without limitation, all Codexis Software). In addition, Codexis shall have a right to conduct an audit to determine that all Codexis materials, information, and/or technology have been destroyed and that such destruction is complete (the “Termination and Divestment Audit Right”). Under the Termination and Divestment Audit Right, Merck shall allow a designee chosen by Codexis and reasonably acceptable to Merck to review documentation, materials, and facilities of Merck as reasonably necessary for such designee to determine whether all Codexis materials, information, and/or technology have been destroyed. Results of such investigation shall be made available to both Merck and Codexis; provided that such designee shall disclose to Codexis only its determination of whether all Codexis materials, information, and/or technology has been destroyed. Merck may require such designee to enter into an appropriate written agreement obligating it to be bound by obligations of confidentiality and restrictions on use of such Information that are comparable to the obligations set forth in Article 10. The Termination and Divestment Audit Right shall continue until the earlier of (a) ten (10) years after the effective date of termination of this Agreement by Codexis pursuant to Section 12.2, 12.3 or 12.5, or by Merck pursuant to Section 12.4 or (b) until a designee determines, pursuant to the Codexis’ exercise of the Termination and Divestment Audit Right, that all Codexis materials, information, and/or technology has been destroyed. All reasonable expenses arising from the first audit shall be at Codexis’ expense, and all subsequent audits, if any, shall be at Merck’s expense.

12.7 Survival. Notwithstanding anything to the contrary in this Agreement:

13. DISPUTE RESOLUTION.

13.1 Resolution by Executive Officers. The Parties agree that the procedures set forth in this Article 13 shall be the exclusive mechanism for resolving any dispute, controversy, or claim, which are not Excluded Claims, (each, a “Dispute”) between the Parties that may arise from time to time pursuant to this Agreement relating to any Party’s rights and/or obligations. Except as otherwise provided in this Agreement, in the event of any Dispute between the Parties in connection with this Agreement, the construction hereof, or the rights, duties or liabilities of either Party hereunder, the Parties shall first attempt in good faith to resolve such Dispute by negotiation and consultation between themselves. In the event that such Dispute is not resolved on an informal basis within ten (10) Business Days, either Party may, by written notice to the other Party, refer the Dispute to the executive officers designated by the Parties for attempted resolution. Such officers, or their designees, shall attempt in good faith to promptly resolve such Dispute within thirty (30) Business Days thereafter. In the event that any matter is not resolved under the foregoing provisions, each Party may, at its sole discretion, seek resolution of such matter in accordance with Section 13.2.

13.2 Arbitration. Subject to Section 13.3, any Dispute referred for arbitration shall be finally resolved by binding arbitration before a panel of three (3) arbitrators in accordance with the rules of the American Arbitration Association (“AAA”) in effect at the time the proceeding is initiated. If the issues in Dispute involve scientific, technical or commercial matters, then any arbitrator chosen under this Agreement shall have educational training and industry experience sufficient to demonstrate a reasonable level of relevant scientific, technical and commercial knowledge relevant to the subject matter of the Dispute. All proceedings and communications as part of the arbitration shall be in English. Following selection of the third arbitrator, the arbitrators shall use all reasonable efforts to complete the arbitration proceedings and render an award within six (6) months after the last arbitrator is appointed. In any such arbitration, the following additional procedures shall apply:

- 49 –

Execution Version

13.2.1 Rules. The arbitration shall be conducted pursuant to the then-current AAA rules in effect for disputes between U.S. parties on the date of commencement of the arbitration; provided, however, that discovery in any arbitration shall be conducted in accordance with the AAA Commercial Arbitration Rules in effect immediately prior to October 1, 2013, for large complex commercial disputes between U.S. based entities.

13.2.2 Panel. Within thirty (30) days after a Party demands arbitration, each Party shall select one (1) arbitrator and the third chosen by the two (2) Party-chosen arbitrators. If either, or both, of Merck or Codexis fails to choose an arbitrator within thirty (30) days after receiving notice of commencement of arbitration or if the two arbitrators fail to choose a third arbitrator within thirty (30) days after their appointment , then either or both Parties shall immediately request that the AAA select the remaining number of arbitrators to be selected, which arbitrator(s) shall have an appropriate background, experience and expertise in the subject matter at issue in the Dispute. The place of arbitration shall be [***], United States of America. The seat of arbitration shall be the State of New York, United States of America (for clarity, the Parties intend this to mean that the procedural rules of the State of New York, United States of America, will apply to any arbitration).

13.2.3 Injunctive Relief; Costs and Expenses. Either Party may apply to the arbitrators for interim injunctive relief until the arbitration decision is rendered or the Dispute is otherwise resolved. Either Party may, without waiving any right or remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending resolution of the Dispute pursuant to this Article 13. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party will share equally the cost and expenses of the panel selected in Section 13.2.2 and any administrative fees unless in each case the arbitrators agree otherwise, which they are hereby empowered, authorized and instructed to do if they determine that to be fair and appropriate. Each Party shall bear its own costs and expenses and attorneys’ fees in connection with any such arbitration; provided, however, that the prevailing Party in any such arbitration shall be entitled to recover from the other Party the reasonable attorneys’ fees, costs and expenses incurred by such prevailing Party in connection with such arbitration.

13.2.4 Confidentiality. Except to the extent necessary to confirm an award or decision or as may be required by Applicable Law, or the requirement of any exchange on which a Party’s shares are traded, neither Party nor any arbitrator may disclose the existence or results of any arbitration without the prior written consent of both Parties. In no event shall any arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the Dispute would be barred by the applicable New York statute of limitations.

13.2.5 Breach of the Agreement. In the event of a Dispute involving the alleged breach of this Agreement (including, without limitation, whether a Party has satisfied its diligence obligations hereunder), (a) neither Party may terminate this Agreement under Section 12.2 until resolution of the Dispute pursuant to this Article 13 and (b) if the arbitrators render a decision that a breach of this Agreement has occurred, the arbitrators shall have no authority to modify the right of the non-breaching Party to terminate this Agreement in accordance with Section 12.2.

13.2.6 Performance. Any disputed performance or suspended performance pending the resolution of a Dispute that the arbitrators determine to be required to be performed by a Party shall be completed within a reasonable time period following the final decision of the arbitrators.

13.2.7 Binding Decision. The decision of the arbitrators shall be the sole, exclusive and binding remedy between the Parties regarding the determination of all Disputes presented. The arbitrators shall prepare and deliver to the Parties a written, reasoned opinion conferring their decision. Judgment on the award so rendered may be entered in any court having competent jurisdiction thereof. Any monetary payment to be made by a Party pursuant to a decision of the arbitrators shall be made in Dollars, free of any tax or other deduction.

13.3 [***]. Notwithstanding anything in this Agreement to the contrary, any and all issues regarding (a) [***], (b) [***], or (c) any other [***], shall be [***]. This Section 13.3 shall not be construed to [***].

14. MISCELLANEOUS.

14.1 Regulatory Responsibilities and Costs. As between the Parties, Merck shall prepare, file, maintain and own all Regulatory Filings and related submissions with respect to all Therapeutic Products and shall bear the cost of such preparation, filing, maintenance and ownership. As between the Parties, Merck shall be solely responsible for communicating with the FDA and/or any other Regulatory Authority in any country or jurisdiction regarding all Therapeutic Products.

14.2 Commercialization Responsibilities and Costs. As between the Parties, Merck shall be solely responsible for all commercialization activities relating to Therapeutic Products, at Merck’s sole cost and expense, and shall have sole decision-making authority with respect to the foregoing. Merck shall conduct all commercialization activities under this Agreement in compliance with all Applicable Law. For clarity, nothing in this Agreement shall require Merck to develop or commercialize any minimum number of Therapeutic Products or limit the number of Therapeutic Products that Merck may develop or commercialize.

14.3 Party Employees. Notwithstanding anything to the contrary under this Agreement, under no circumstance would any employee, contractor, contingent worker or consultant of a Party be considered an employee, contractor, contingent worker or consultant of the other Party. The Party who sends any employee, contractor, contingent worker or consultant to work at the other Party’s premises shall assume all liability for such employees, contractors, contingent workers or consultants working at the other Party’s premises and shall procure that its employees, contractors, contingent workers or consultants comply with all security, health and safety and other policies applicable to occupiers of the hosting Party’s premises.

Execution Version

14.4 Non-Solicitation. During the period beginning on the Effective Date and ending on the date that is [***] (the “Non-Solicitation Period”), neither Party shall directly or indirectly, solicit, hire, employ or attempt to solicit, hire or employ any person acting in a scientific role who is or was an employee or contractor of the other Party or such other Party’s Affiliates during the Non-Solicitation Period, or in any other way directly or indirectly seek to solicit, induce, bring about, influence, promote, facilitate, or encourage any such individual to work for such Party; provided that the foregoing shall not restrict a Party or its Affiliates from advertising employment opportunities in any manner that does not directly target the other Party or its Affiliates or from hiring or employing any person who responds to such generalized public advertisements.

14.5 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use reasonable efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision (s) which, insofar as practical, implement the purposes of this Agreement.

Exhibit 1.20

Codexis Core Technology

The enzyme optimization process starts by identifying genes that code for enzymes known to have the general type of catalytic reactivity for a desired chemical reaction. Typically, we identify gene sequences in published databases and then synthesize candidate genes having those sequences. Using a variety of biotechnology tools, we diversify these genes by introducing mutations, giving rise to changes in the enzymes for which they encode. The methods for diversifying these genes, and types of diversity being tested, often vary over the course of an enzyme optimization program. For finding initial diversity, methods typically include random mutagenesis and site-directed (included structure-guided) mutagenesis. We also test mutational variations that distinguish related enzymes among different organisms. Once we have identified potentially beneficial mutations, we test combinations of these mutations in libraries made using our proprietary gene recombination methodologies, gene shuffling and multiplexed gene SOEing, or Splicing by Overlap Extension.

With our proprietary gene shuffling methodology, we generate libraries of genes that have random combinations of the mutations we are testing. The pool of genes is used to transform host cells, which entails introducing the various genes, one by one, into host cells. These cells are then segregated and grown into colonies. Cells from individual colonies are cultured in high throughput to produce the enzyme encoded by the shuffled gene in those cells. The enzymes are then screened in high throughput using test conditions relevant to the desired process. The screening results identify individual shuffled genes that produce improved enzymes having combinations of beneficial mutations and weed out enzymes having detrimental ones. Using different test conditions and/or different analytical methods, we can identify variant enzymes that exhibit various improved performance characteristics, such as stability, activity and selectivity, under conditions relevant to the desired chemical process.

In the next step in our optimization process, we use our proprietary software tool, ProSAR™, to analyze protein sequence-activity relationships. ProSAR™ aids in identifying specific gene and enzyme mutations that are beneficial, neutral or detrimental with respect to the desired performance characteristics. Earlier directed evolution methods did not separately evaluate individual mutations in libraries of variants which carry multiple mutations, where beneficial and detrimental performance characteristics may be mixed in an individual gene or enzyme. Capitalizing on the advent of inexpensive gene sequencing, we are able to determine which particular mutations are present in the genes and proteins we have screened. Our ProSAR™ bioinformatics software relates the screening results to the mutations and ranks the individual mutations with regard to their degree of benefit or detriment, relative to whichever process parameter(s) the screening tested. Using that information, we can bias the pool of mutational diversity in the next iteration to further the accumulation of beneficial diversity and cancel out detrimental diversity in the individual genes in the resulting shuffled library. The ProSAR™ results also help us develop ideas about new diversity to test. ProSAR™, combined with efficient gene synthesis and high quality library generation methods, has led to a significant increase in the efficiency and speed of enzyme improvement and optimization.

In another step of our optimization process, we take the best variants we have identified and prepare enough of each to test in the desired chemical process at laboratory scale, for in-process confirmation. This optimization routine is done iteratively, typically adding new diversity to the pool in each iteration. The gene that codes for the best performing enzyme in one iteration is used as the starting gene for the next iteration of shuffling and screening. As the enzymes improve over these iterations, the screening conditions are made increasingly more stringent. In this way, enzymes are rapidly optimized until all in-process performance requirements have been achieved and the economic objectives for the desired process have been met.

Multiplexed gene SOEing is our proprietary methodology for rapidly generating gene variants. Using multiplexed gene SOEing, we rapidly generate collections of individual gene variants that have predetermined, as opposed to random, combinations of mutations we are testing. It is based on a biotechnology technique, which we refer to as SOEing, generally used to make a hybrid, or spliced, gene from fragments of two genes and/or to introduce a specific mutation into a splice between fragments of one gene. We have automated the process to make robotically, in parallel, one hundred to several hundred variants, each with a predetermined combination of the mutations we are testing. The variants are introduced into host cells, and the encoded enzyme is produced and screened in high throughput, as described above.

Using multiplexed gene SOEing, we can test many mutations and combinations thereof in parallel, and because the mutation incorporation is controlled and predetermined before screening, as opposed to random incorporation and selection after screening, the resulting data set can be more optimal for ProSAR™ analysis.

We believe using multiplexed gene SOEing to survey many mutations quickly, followed by ProSAR™-driven shuffling of beneficial mutations, is a particularly effective approach, providing rapid gains in enzyme performance.

Codexis Announces CodeEvolver Technology Transfer and License Agreement with Merck

Codexis to Receive $5 Million in Upfront Payment

Codexis to Hold Conference Call on [Day/Date] at [xx:xx a.m./p.m.] Eastern Time

REDWOOD CITY, Calif. (August XX, 2015) – Codexis, Inc. (NASDAQ: CDXS), a leading developer of biocatalysts for the pharmaceutical and fine chemical industries, announces the signing of a CodeEvolver^®platform technology license agreement with Merck, known as MSD outside the United States and Canada, through a subsidiary. This transaction marks the second CodeEvolver licensing agreement between Codexis and a major pharmaceutical company and advances the technology’s business model of multiple sources of revenue.

Under the terms of the agreement, Codexis has granted Merck a non-exclusive license to use Codexis’ proprietary CodeEvolver protein engineering platform technology to develop novel enzymes for use in the manufacture of Merck’s pharmaceutical products. Upon completion of the technology transfer a Codexis’ CodeEvolver protein engineering platform will be located at a Merck research site.

Codexis is eligible to receive up to $18 million over approximately the next 15 to 24 months, $5 million of which will be paid upon the signing of this agreement and an additional $13 million subject to the satisfactory completion of certain technology transfer milestones. Codexis will also be eligible to receive payments of up to maximum of $15 million for each pharmaceutical ingredient (API) using novel enzymes developed by Merck using the CodeEvolver technology and used for commercial manufacturing purposes.

“This licensing transaction builds upon our productive eight-year relationship with Merck and further validates the ability of CodeEvolver to effectively and cost-efficiently improve certain manufacturing processes,” stated John Nicols, President and CEO of Codexis. “We view licensing agreements involving our CodeEvolver technology such as this one with Merck as an attractive component of our business model. It allows us to monetize our core technology, while continuing to provide services and supply products to customers under our traditional business model.”
