If the Dispute has not been resolved within thirty (30) days after the Dispute Notice has been sent by a party to its Executive Officers and to the Executive Officers of the other party or parties, then either the party that has sent the Dispute Notice, or the party or parties that have received the Dispute Notice may, by written notice to the other party or parties, elect to submit the Dispute to arbitration pursuant to Section 8.6.2. If a party's Executive Officer intends to be accompanied at a meeting by an attorney, the Executive Officers of the other party shall be given at least seventy-two (72) hours' notice of such intention and may also be

accompanied by an attorney. All negotiations conducted pursuant to this Section 8.6.1, and all documents and information exchanged by the parties in furtherance of such negotiations, (i) are the Confidential Information (as defined in Section 8.6.4) of the parties, and (ii) shall be inadmissible in any arbitration conducted pursuant to this Section 8.6 or other proceeding with respect to a Dispute.

8.6.2 Arbitration.

(a) All Disputes arising out of, relating to or in connection with this Agreement, which have not been resolved pursuant to Section 8.6.1, shall be submitted to mandatory, final and binding arbitration before an arbitral tribunal pursuant to the Rules of Arbitration of the International Court of Arbitration of the International Chamber of Commerce (the “ICC Rules”), in effect at the time of filing of the request for arbitration, as modified hereby. The International Court of Arbitration of the International Chamber of Commerce (the “ICC Court”) shall administer the arbitration.

(b) There shall be three (3) arbitrators. If there are two parties to the arbitration, then one arbitrator shall be nominated by the initiating claimant party in the request for arbitration, the second nominated by the respondent party within thirty (30) days of receipt of the request for arbitration, and the third (who shall act as chairperson of the arbitral tribunal) nominated by the two (2) party-appointed arbitrators within thirty (30) days of the selection of the second arbitrator. In the event that either party fails to nominate an arbitrator, or if the two party-appointed arbitrators are unable or fail to agree upon the third arbitrator, within the time periods specified herein, the ICC Court shall appoint the remaining arbitrator(s) required to comprise the arbitral tribunal. If there are more than two parties to the arbitration, the claimant(s) shall jointly nominate one arbitrator and the respondent(s) shall jointly nominate one arbitrator, within thirty (30) days of receipt by respondent(s) of a copy of the request for arbitration. For avoidance of doubt, where there are two or more claimant(s), none of the claimants has to nominate an arbitrator in their request for arbitration. The third arbitrator (who shall act as chairperson of the arbitral tribunal) shall be nominated by the two (2) party-appointed arbitrators within thirty (30) days of the nomination of the second arbitrator. If either the claimant(s) or the respondent(s) fail to timely nominate an arbitrator, or if the two party-appointed arbitrators are unable or fail to agree upon the third arbitrator, within the time periods specified herein, then on the request of any party, the ICC Court shall appoint the remaining arbitrator(s) required to comprise the arbitral tribunal. The claimant in the arbitration shall provide a copy of the request for arbitration to the respondent at the time such request is submitted to the Secretariat of the International Chamber of Commerce.

(c) Each arbitrator chosen under this Section shall speak, read, and write English fluently and shall be either (i) a practicing lawyer who has specialized in business litigation with at least ten (10) years of experience in a law firm, (ii) an arbitrator experienced with commercial disputes, or (iii) a retired judge.

(d) The place of arbitration shall be Paris, France. The language of the arbitral proceedings and of all submissions and written evidence and any award issued by the arbitral tribunal shall be English. Any party may, at its own expense, provide for translation of any documents submitted in the arbitration or translation or interpretation of any testimony taken at any hearing before the arbitral tribunal. For the avoidance of doubt, no party is under any

obligation to provide for translation of any documents submitted in the arbitration or translation or interpretation of any testimony taken at any hearing before the arbitral tribunal.

(e) The award shall be in writing, state the reasons for the award and be final and binding. The arbitral tribunal shall, subject to its discretion, endeavor to issue its award within four (4) months of the end of the hearing, or as soon as possible thereafter. It is expressly understood and agreed by the parties that the rulings and award of the arbitral tribunal shall be binding on the parties, their successors and permitted assigns. Judgment on the award rendered by the arbitral tribunal may be entered in any court having competent jurisdiction.

(f) Each party shall bear its own costs and expenses and attorneys' fees, and the party that does not prevail in the arbitration proceeding, as determined by the arbitral tribunal, shall pay the arbitrator's fees and any administrative fees of arbitration. All proceedings and decisions of the tribunal shall be deemed Confidential Information of each of the Parties, and shall be subject to Section 8.6.4.

8.6.3 Interim Relief.

(a) The arbitral tribunal shall have the power to grant any remedy or relief that it deems appropriate, whether provisional or final, including conservatory relief and injunctive relief, and any such measures ordered by the arbitral tribunal may, to the extent permitted by applicable law, be deemed to be a final award on the subject matter of the measures and shall be enforceable as such.

(b) In addition to the remedies and relief available under Section 8.6.3(a) above and the ICC Rules, and subject to Section 8.6.2 above, each party expressly retains the right at any time to apply to any court of competent jurisdiction for interim, injunctive, provisional or conservatory relief, including pre-arbitral attachments or injunctions, and any such request shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate.

(c) For purposes of Section 8.6.3(b), each party hereby irrevocably and unconditionally consents and agrees that any action for interim, provisional and/or conservatory relief brought against it with respect to its obligations or liabilities under or arising out of or in connection with this Agreement may be brought in the courts located in Paris, France or the state or federal courts located in the Borough of Manhattan, New York City, New York, and each party hereby irrevocably accepts and unconditionally submits to the non-exclusive jurisdiction of the aforesaid courts in personam, with respect to any such action for interim, provisional or conservatory relief. In any such action, each of the parties irrevocably waives, to the fullest extent they may effectively do so, any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens or any right of objection to jurisdiction on account of its place of incorporation or domicile, which it may now or hereafter have to the bringing of any such action or proceeding in the courts located in Paris, France or the state or federal courts located in the Borough of Manhattan, New York City, New York.

(d) Each party hereby irrevocably consents and agrees that the service of any and all legal process, summons, notices and documents which may be served in any action arising under this Agreement may be made by sending a copy thereof by express courier to the party to be served at the address set forth in the notice provision of this Agreement, with such

service to be effective upon receipt. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

(e) Each party hereto hereby irrevocably waives any and all right to trial by jury in any legal proceeding brought pursuant to this Section 8.6.

8.6.4 Confidentiality. The Company and each of the Purchasers agree to use, and to use its reasonable best efforts to ensure that its authorized representatives use the same degree of care as such party uses to protect its own confidential information (but in no event less than reasonable care) to keep confidential the information provided to it pursuant to this Agreement, and any other information furnished to it which the disclosing party identifies as being confidential or proprietary (so long as such information is not in the public domain) or, under the circumstances surrounding disclosure, such party knows or has reason to know should be treated as confidential (“Confidential Information”), unless otherwise required by law (provided that a party shall, to the extent permitted by law, promptly notify the other party of any required disclosure and take reasonable steps to minimize the extent of any such required disclosure); provided, however, that Confidential Information shall not include information, that (i) was in the public domain prior to the time it was furnished to such recipient, (ii) is at the time of the alleged breach (through no willful or improper action or inaction by such recipient) generally available to the public, (iii) was rightfully disclosed to such recipient by a third party without restriction or (iv) as of the time of the alleged breach, had been independently developed (as evidenced by written records) without any use of Confidential Information.

8.7. Severability. In the event that any provision of this Agreement or the application of any provision hereof is declared to be illegal, invalid, or otherwise unenforceable by a court of competent jurisdiction, the remainder of this Agreement shall not be affected except to the extent necessary to delete such illegal, invalid, or unenforceable provision unless that provision held invalid shall substantially impair the benefits of the remaining portions of this Agreement.

8.8. Headings. The headings in this Agreement are for convenience of reference only and shall not constitute a part of this Agreement, nor shall they affect its meaning, construction, or effect.

8.9. Entire Agreement. This Agreement embodies the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to the subject matter hereof.

8.10. Finder's Fee. The Company agrees that it shall be responsible for the payment of any placement agent's fees, financial advisory fees, or brokers' commissions (other than for persons engaged by Purchaser) relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold each Purchaser harmless against, any liability, loss or expense (including, without limitation, attorney's fees and out-of-pocket expenses) arising in connection with any claim for any such fees or commissions.

8.11. Expenses. Each party will bear its own costs and expenses in connection with this Agreement; provided, however, the Company will pay (or reimburse the lead investor or its affiliates) for the legal fees and expenses of Xxxxxx Xxxxxxx Xxxxxx & Xxxxxxxx LLP incurred in connection with its role as counsel to the lead investor in the transactions contemplated by this Agreement up to a maximum of Ninety Thousand Dollars ($90,000).

8.12. Further Assurances. The parties agree to execute and deliver all such further documents, agreements and instruments and take such other and further action as may be necessary or appropriate to carry out the purposes and intent of this Agreement.

8.13. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other party. Facsimile signatures shall be deemed originals for all purposes hereunder.

18.14. Independent Nature of Purchasers' Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with obligations of each other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement or any other Transaction Agreements. The decision of each Purchaser to purchase Shares pursuant to this Agreement has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of the subsidiary which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any other Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any ancillary document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Agreement. Each Purchaser acknowledges that no other Purchaser has or will be acting as agent of such Purchaser in enforcing its rights under this Agreement or any other Transaction Agreements. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Purchaser, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The Purchasers acknowledge that Xxxxxx Xxxxxxx Xxxxxx & Xxxxxxxx LLP has represented only Naxyris, SA in connection with the transactions contemplated by this Agreement and not any other Purchaser.

8.15. Waiver of Conflicts; Representation by Counsel. Each Purchaser and the Company is aware that Fenwick & West LLP (“F&W”) may have previously performed and may continue to perform certain legal services for certain of the Purchasers in matters unrelated to F&W's representation of the Company. In connection with its Purchaser representation, F&W may have obtained confidential information of such Purchasers that could be material to F&W's representation of the Company in connection with negotiation, execution and performance of this Agreement. By signing this Agreement, each Purchaser and the Company hereby acknowledges that the terms of this Agreement were negotiated among the Purchasers and the Company and are fair and reasonable and waives any potential conflict of interest arising out of such representation (including any future representation of such parties) or such possession of confidential information and consents to the investment by such affiliate of F&W. Each Purchaser and the Company further represents that it has had the opportunity to be, or has been, represented by

separate independent counsel in connection with the transactions contemplated by this Agreement, including, without limitation, the waivers contained in this Section 8.15.

Opinion of Company Counsel

February 23, 2012

To the Purchasers of Common Stock of

Amyris, Inc. Who are Listed as Investing

on the Date Hereof on the Signature Pages to the Purchase Agreement

Ladies and Gentlemen:

We have acted as counsel for Amyris, Inc., a Delaware corporation (the "Company"), in connection with the sale on the date hereof by the Company to you of 10,160,325 shares of the Company's Common Stock (the "Shares") pursuant to the Stock Purchase Agreement, dated as of February 22, 2012 (the "Purchase Agreement"), among the Company and the parties whose names appear on the signature pages thereto (the "Purchasers"), and the execution and delivery by the Company of the Amendment No. 1 To Amended and Restated Investors' Rights Agreement (the "Rights Agreement"), dated as of February 23, 2012. This opinion is given to you pursuant to Article 6(a) of the Purchase Agreement in connection with the Closing of the sale of the Shares. The Purchase Agreement, the Rights Agreement, and that certain side letter between the Company and certain of the Purchasers (the “Side Letter”), dated as of February 23, 2012 are referred to herein collectively as the "Transaction Documents." Unless defined herein, capitalized terms used herein have the meaning given to them in the Purchase Agreement.

We have examined such matters of law as we reasonably considered necessary for the purpose of rendering this opinion. As to matters of fact material to the opinions expressed herein, we have relied upon the representations and warranties as to factual matters contained in, and made by the Company pursuant to, the Purchase Agreement and upon certificates and statements of government officials and of officers of the Company, including but not limited to a certificate of the Company to us (the "Opinion Certificate"). In addition, we have examined originals or copies of documents, corporate records and other writings that are listed in Exhibit A attached hereto (the “Reviewed Agreements”) and have not conducted any other factual examination except as listed on Exhibit A. In such examination, we have assumed that the signatures on documents and instruments examined by us are authentic, that each is what it purports to be, and that all documents and instruments submitted to us as copies or facsimiles conform with the originals, which facts we have not independently verified.

In making our examination of documents (including the Transaction Documents) and rendering our opinions, we have further assumed that, except for the Company with respect to the Transaction Documents, (a) each party to such documents had the entity power and entity authority to enter into and perform all of such party's obligations thereunder, (b) each party to such documents has duly authorized, executed and delivered such documents and (c) each of such documents is enforceable against and binding upon the parties thereto. We have also assumed that (i) the representations and warranties of the Purchasers set forth in the Transaction Documents are accurate and complete, (ii) there is no fact or circumstance relating to you or your business that might prevent you from enforcing any of your rights provided for in the Transaction Documents and (iii) there are no extrinsic agreements or understandings among the parties to the Transaction Documents or among the parties to the Reviewed Agreements expressly identified on Exhibit A hereto, that would modify or interpret the terms of the

To the Purchasers of Common

Transaction Documents or Reviewed Agreements or the respective rights or obligations of the parties thereto.

Notwithstanding the examination described above, the expressions "to our knowledge," "known to us," "our actual knowledge" or words of similar import when used in this opinion letter, refer to the current actual knowledge of attorneys within the firm who have rendered legal services to the Company in 2012 and means that, while such attorneys have not been informed by the Company that a matter stated is factually incorrect, we have made no independent factual investigation with respect to such matter. No inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company or the rendering of the opinions set forth below.

Where statements in this opinion concerning the Company, or an effect on the Company, are qualified by the term "material" or "materially," those statements involve judgments and opinions as to the materiality or lack of materiality of any matter to the Company's business, assets, results of operations or financial condition that are entirely those of the Company and its officers.

We express no opinion as to matters governed by any laws other than the laws of the State of California, the Delaware General Corporation Law (the "DGCL") and the federal law of the United States of America, including the rules and regulations promulgated by governmental authorities thereunder, as such laws, rules and regulations exist on the date hereof (collectively, "Applicable Laws"). We express no opinion as to whether the laws of any particular jurisdiction apply, or to the extent that the laws of any jurisdiction other than those identified above are applicable to the Transaction Documents or the transactions contemplated thereby.

In rendering the opinion set forth in paragraph (1) (Qualification to Do Business) below as to the valid existence and good standing of the Company under the laws of the State of Delaware and as to its qualification to do business as a foreign corporation in good standing under the laws of the State of California, we have relied exclusively on certificates of public officials and the Opinion Certificate.

In rendering the opinion set forth in paragraph (2) (Authority and Power to Do Business) below concerning the Company's corporate power and corporate authority to conduct its business as it is presently conducted and as to the types of businesses the Company presently conducts, we have relied exclusively upon representations made to us in the Opinion Certificate.

We note that the parties to the Purchase Agreement have designated the laws of the State of Delaware as the laws governing the Purchase Agreement. Notwithstanding the designation therein of the laws of the State of Delaware, our opinion in paragraph (4) (Enforceability) below as to the validity, binding effect and enforceability of the Purchase Agreement is premised upon the results that would be obtained if a California court were to apply the internal laws of the State of California to contracts made between California residents present in California when the Purchase Agreement is entered into and, where applicable, the currently effective DGCL, without regard to laws regarding choice of law or conflict of laws.

In rendering the opinion in paragraph (6) (No Violations) below relating to violations of Applicable Laws, and paragraph (7) (No Consents) below relating to consents, approvals, authorizations and filings under, or pursuant to, Applicable Laws, such opinions are limited to Applicable Laws that in our experience are typically applicable to transactions of the nature provided for in the Transaction Documents. Moreover, we render no opinion in such paragraphs, or in paragraph (4) (Enforceability), regarding the Company's compliance with applicable securities laws, including but not limited to laws regarding the registration or qualification of the offer and sale of securities, or the registration by the Company under any such securities laws, and no such opinion should be inferred from the language of those paragraphs. Any opinion rendered in connection with applicable securities laws is rendered solely and expressly in paragraphs (8) (Securities Law Compliance) and (9) (Not an Investment Company) below.

In rendering the opinion in paragraph (7) (No Violations) below regarding breach of, or default under, any Reviewed Agreements set forth in Exhibit A, we have not reviewed, and express no opinion on, (a) financial covenants or similar provisions requiring financial calculations or determinations to ascertain whether there is any breach or default nor (b) provisions relating to the occurrence of a "material adverse event" or words of similar import. We also do not express any opinion on parol evidence bearing on interpretation or construction of such Reviewed Agreements, or on any oral modifications to such Reviewed Agreements made by the parties thereto. Moreover, to the extent that any of the Reviewed Agreements are governed by the laws of any jurisdiction other than the State of California our opinion relating to those agreements is based solely upon the plain meaning of their language as though California law applied, without regard to interpretation or construction that might be indicated by the laws stated as governing those agreements.

In rendering the opinion expressed in paragraph (8) (Securities Law Compliance) below, we have assumed the accuracy of, and have relied upon, the Company's representations to us that the Company has made no offer to sell the Shares by means of any general solicitation or publication of any advertisement therefor, and we have assumed that the offer and sale of the Shares is not integrated with any future securities offering of the Company.

This opinion is qualified by, and we render no opinion with respect to, or as to the effect of, the following:

(a)bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting the relief of debtors or the rights and remedies of creditors generally, including without limitation the effect of statutory or other law regarding fraudulent transfers, preferential transfers and equitable subordination;

(b)general principles of equity, including but not limited to judicial decisions holding that certain provisions are unenforceable when their enforcement would violate the implied covenant of good faith and fair dealing, would be commercially unreasonable or involve undue delay, whether or not such principles or decisions have been codified by statute, or that result from the exercise of the court's discretion;

In accordance with Section 95 of the American Law Institute's Restatement (Third) of the Law Governing Lawyers (2000), this opinion letter is to be interpreted in accordance with customary practices of lawyers rendering opinions to third parties in transactions of the type provided for in the Transaction Documents.

Based upon and subject to the foregoing, and except as set forth in the Purchase Agreement, as of immediately prior to the Closing we are of the following opinion.

(1)The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The Company is qualified to do business as a foreign corporation in good standing under the laws of the State of California.

(2)The Company has all corporate power and corporate authority required to execute, deliver and perform its obligations under the Transaction Documents.
