Notwithstanding anything contained in this Agreement to the contrary and without implication that the contrary would otherwise be true, the Company expressly acknowledges and agrees that no Purchaser shall have (unless expressly agreed to by a particular Purchaser after the date hereof in a written definitive and binding agreement executed by the Company and such particular Purchaser (it being understood and agreed that no Purchaser may bind any other Purchaser with respect thereto)), any duty of confidentiality with respect to, or a duty not to trade on the basis of, any material, non-public information regarding the Company or any of its Subsidiaries.

7.2. Form D. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to the Investor (provided that the posting of the Form D on the SEC’s XXXXX system shall be deemed delivery of the Form D for purposes of this Agreement).

7.3. Removal of Legends and Transfer Restrictions. Removal of Legends. Certificates evidencing Securities shall not be required to contain the legend set forth in Section 4.12 above or any other legend (i) while a registration statement covering the resale of such Securities is effective under the Securities Act, (ii) following any sale of such Securities pursuant to Rule 144 (assuming the transferor is not an affiliate of the Company), (iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144 (provided that a Purchaser provides the Company with reasonable assurances that such Securities are eligible for sale, assignment or transfer under Rule 144 and Purchaser’s acknowledgment of the requirement to sell, assign or transfer the Securities in accordance with Rule 144 or another exemption from the registration requirements of the Securities Act which shall not include an opinion of Purchaser’s counsel), (iv) in

connection with a sale, assignment or other transfer (other than under Rule 144), provided that such Purchaser provides the Company with an opinion of counsel to such Purchaser, in a generally acceptable form, to the effect that such sale, assignment or transfer of the Securities may be made without registration under the applicable requirements of the Securities Act or (v) if such legend is not required under applicable requirements of the Securities Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than three (3) Trading Days (as defined in the Warrants) following the delivery by a Purchaser to the Company or the transfer agent (with notice to the Company) of a legended certificate representing such Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from such Purchaser as may be required above in this Section 7.4(a), as directed by such Purchaser, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated Securities Transfer Program and such Securities are Shares or Warrant Shares, credit the aggregate number of shares of Common Stock to which such Purchaser shall be entitled to such Purchaser’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to such Purchaser, a certificate representing such Securities that is free from all restrictive and other legends, registered in the name of such Purchaser or its designee (the date by which such credit is so required to be made to the balance account of such Purchaser’s or such Purchaser’s designee with DTC or such certificate is required to be delivered to such Purchaser pursuant to the foregoing is referred to herein as the “Required Delivery Date”, and the date such shares of Common Stock are actually delivered without restrictive legend to such Purchaser or such Purchaser’s designee with DTC, as applicable, the “Share Delivery Date”). The Company shall be responsible for any transfer agent fees or DTC fees with respect to any issuance of Securities or the removal of any legends with respect to any Securities in accordance herewith. The Company acknowledges that the remedy at law for a breach of its obligations under this Section 7.3 may be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 7.3 with respect to any Purchaser, the Purchaser shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

7.4. Subsequent Equity Sales. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Investors, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any trading market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

7.5. Listing. The Company shall promptly take any action required to maintain the listing of all of the Shares and the Warrant Shares, once they have been issued, upon each national securities exchange and automated quotation system, if any, upon which shares of

Common Stock are then listed (subject to official notice of issuance) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all Shares from time to time issuable under the terms of the Transaction Agreements. The Company shall take all actions within its control to comply with the reporting requirements of the Exchange Act and each applicable national securities exchange and automated quotation system on which the Common Stock is listed. The Company shall make and keep public information available, as those terms are understood and defined in SEC Rule 144, for so long as required in order to permit the resale of the Securities pursuant to SEC Rule 144 and to file period reports with the SEC whether or not required to do so. The Company shall not take any action which would be reasonably expected to result in the delisting or suspension of the Common Stock on The NASDAQ Stock Market.

7.6. Stockholders Meeting. The Company shall provide each stockholder entitled to vote at a special or annual meeting of stockholders of the Company (the “Stockholder Meeting”), which initially shall be promptly called and held not later than October 31, 2015 (the “Stockholder Meeting Deadline”), a proxy statement substantially in the form which has been previously reviewed by the Purchasers and a counsel of their choice, at the expense of the Company, soliciting each such stockholder’s affirmative vote at the Stockholder Meeting for approval of resolutions (the “Stockholder Resolutions”) providing for the Company’s issuance of all of the Securities as described in the Agreement in accordance with applicable law and rules and regulations of The NASDAQ Stock Market, including the issuance of the Warrant Shares upon exercise of the Warrants (such affirmative approval being referred to herein as the “Stockholder Approval” and the date such approval is obtained, the “Stockholder Approval Date”), and the Company shall use its best efforts to solicit its stockholders’ approval of the Stockholder Resolutions and to cause the Board to recommend to the stockholders that they approve the Stockholder Resolutions. The Company shall be obligated to seek to obtain the Stockholder Approval by the Stockholder Meeting Deadline. If, despite the Company’s best efforts, the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, the Company shall cause an additional Stockholder Meeting to approve the Stockholder Resolutions to be called and held at each otherwise convened special or annual meeting of the stockholders of the Company, which special or annual meetings must be called and held at least once in each six-month period after the Stockholder Meeting Deadline until such Stockholder Approval is obtained, provided that if the Board does not recommend to the stockholders that they approve the Stockholder Resolutions at any such Stockholder Meeting and the Stockholder Approval is not obtained, the Company shall cause an additional Stockholder Meeting to be held each calendar quarter after the Stockholder Meeting Deadline until such Stockholder Approval is obtained.

7.7. Proxy Filing. The Company shall prepare and file with the SEC, within ten (10) business days after the date of this Agreement, a proxy statement in preliminary form relating to the Stockholders Meeting (as defined in Section 7.6) (such proxy statement, including any amendment or supplement thereto, the “Proxy Statement”). The Company shall cause the Proxy Statement to comply in all material respects with the applicable provisions of the Exchange Act and the rules and regulations thereunder. The Company shall cause the definitive Proxy Statement to be mailed as promptly as possible after the date the staff of the SEC advises that it has no further comments thereon or that the Company may commence mailing the Proxy Statement.

7.8. Voting Agreements. Until the Stockholder Approval is obtained, the Company shall not take any action, including the issuance of shares of Common Stock pursuant to any Offering, that would result in the Voting Stockholders and any additional stockholder with whom the Company enters into a Voting Agreement to hold less than a majority of the Company’s outstanding voting stock entitled to vote at the Stockholders Meeting (after taking into account the Exchanges (as defined in the Exchange Agreement) and any bona fide equity financings consummated by the Company on or prior to the date of the Stockholders Meeting).

ARTICLE 8

MISCELLANEOUS

8.1. Survival. The representations, warranties and covenants contained herein shall survive the execution and delivery of this Agreement and the sale of the Securities.

8.2. Indemnification.

(a) Indemnification of Purchasers. The Company agrees to indemnify and hold harmless each Purchaser and its Affiliates and their respective directors, officers, trustees, members, managers, employees and agents, and their respective successors and assigns, from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and other expenses reasonably incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) to which such Person may become subject as a result of any breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under this Agreement, and will reimburse any such Person for all such Losses as they are incurred by such Person.

(b) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt notice to the Company of any claim with respect to which it seeks indemnification and (ii) permit the Company to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (a) the Company has agreed to pay such fees or expenses, or (b) the Company shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such Person or (c) in the reasonable judgment of any such Person, based upon written advice of its counsel, a conflict of interest exists between such Person and the Company with respect to such claims (in which case, if the Person notifies the Company in writing that such Person elects to employ separate counsel at the expense of the Company, the Company shall not have the right to assume the defense of such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the Company of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the Company in the defense of any such claim or litigation. It is understood that the Company shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. The Company will not, except with the consent of the indemnified party, which consent shall not be unreasonably withheld, conditioned or delayed,

consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. No indemnified party will, except with the consent of the Company, consent to entry of any judgment or enter into any settlement.

8.3. Assignment; Successors and Assigns. This Agreement may not be assigned by either party without the prior written consent of the other party; provided, that this Agreement may be assigned by any Purchaser to the valid transferee of any security purchased hereunder if such security remains a “restricted security” under the Securities Act. This Agreement and all provisions thereof shall be binding upon, inure to the benefit of, and are enforceable by the parties hereto and their respective successors and permitted assigns.

8.4. Notices. All notices, requests, and other communications hereunder shall be in writing and will be deemed to have been duly given and received (a) when personally delivered, (b) when sent by facsimile upon confirmation of receipt, (c) one business day after the day on which the same has been delivered prepaid to a nationally recognized courier service, or (d) five business days after the deposit in the United States mail, registered or certified, return receipt requested, postage prepaid, in each case addressed to, as to the Company, Amyris, Inc., 0000 Xxxxxx Xxxxxx, Xxxxx 000, Xxxxxxxxxx, XX 00000, Attn: General Counsel, facsimile number: (000) 000-0000, with a copy to Fenwick & West LLP, 000 Xxxxxxxxxx Xxxxxx, Xxxxxxxx Xxxx, XX 00000, Attn: , Esq., facsimile number: (000) 000-0000, and as to the Purchaser at the address and facsimile number set forth below the Purchaser’s signature on the signature pages of this Agreement. Any party hereto from time to time may change its address, facsimile number, or other information for the purpose of notices to that party by giving notice specifying such change to the other parties hereto. Each Purchaser and the Company may each agree in writing to accept notices and other communications to it hereunder by electronic communications pursuant to procedures reasonably approved by it; provided that approval of such procedures may be limited to particular notices or communications.

8.5. Governing Law. This Agreement, and the provisions, rights, obligations, and conditions set forth herein, and the legal relations between the parties hereto, including all disputes and claims, whether arising in contract, tort, or under statute, shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to its conflict of law provisions.

8.6. Dispute Resolution.

8.6.1 Escalation. Prior to commencing any arbitration in connection with any dispute, controversy or claim arising out of relating to this Agreement or the breach, termination or validity thereof (“Dispute”), the parties shall first engage in the procedures set forth in this Section 8.6.1. Such Dispute shall first be referred by written notice of the Dispute (the “Dispute Notice”) from any party to its executive officers and to the executive officers of each party that the party sending the Dispute Notice has the Dispute with (the “Executive Officers”) and the Executive Officers shall attempt to resolve such Dispute within ten (10) days after a party sent the Dispute Notice to the Executive Officers by meeting (either in person or by video teleconference, unless otherwise mutually agreed) at a mutually acceptable time, and thereafter as often as they reasonably deem necessary, to exchange relevant information and to attempt to

resolve the Dispute. 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 the New York City, New York. 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.

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.

8.14. 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 Securities 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 any of its subsidiaries 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.

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. 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

July 29, 2015

To the Investors 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 16,025,642 shares (the “Shares”) of the Company's Common Stock (“Common Stock”) and warrants to purchase shares of the Company’s Common Stock (the “Warrant Shares” and together with the Shares, the “Securities”) pursuant to the Securities Purchase Agreement, dated as of July 24, 2015 (the “Purchase Agreement”), among the Company and the parties whose names appear on the signature pages thereto (the “Investors”), and the execution and delivery by the Company of the (i) Amendment No. 6 to Amended and Restated Investors' Rights Agreement (the “Rights Agreement Amendment”), dated as of July 29, 2015, (ii) the Registration Rights Letter entered into by the Company with certain stockholders listed on Schedule I thereto (the “Rights Letter”) (iii) the Voting Agreement entered into by the Company with each respective Voting Stockholder (the “Voting Agreement”) and (iv) the Warrants. This opinion is given to you pursuant to Article 6(d) of the Purchase Agreement in connection with the Closing of the sale of the Securities. The Purchase Agreement, the Rights Letter, the Voting Agreement and the Warrants are referred to herein together 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 Investors 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 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 connection with the Transaction Documents 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 opinions set forth herein, although the aggregate number of shares of Common Stock issuable upon the exercise of all of the Warrants as of the date hereof is not determinable, we have assumed that, (i) the Company has a sufficient number of authorized and unissued shares of Common Stock currently available for the total number of shares of Common Stock exercisable as of the date hereof, (ii) as of each and every time any of the Warrants are exercised and/or converted after the date hereof, the Company will have a sufficient number of authorized and unissued shares of Common Stock available for issuance under the Restated Certificate to permit full exercise and/or conversion of each of the Warrants in accordance with its terms without the breach or violation of any other agreement, commitment or obligation of the Company and (iii) in the event that any of the Warrants are exercised and/or converted after the date hereof and the Company does not have a sufficient number of authorized and unissued shares of Common Stock available for issuance under the Restated Certificate, the Company will take all necessary corporate action to authorize a sufficient number of shares of Common Stock for exercise of such Warrants.

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 (10) (Not an Investment Company) below.

In rendering the opinion in paragraph (6) (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 or the Warrants by means of any general solicitation or publication of any advertisement therefor, and we have assumed that the offer and sale of the Shares and the Warrants 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;

(c) Section 1670.5 of the California Civil Code or any other California or United States federal law or provision of the DGCL or equitable principle which provides that a court may refuse to enforce, or may limit the application of, a contract or any clause thereof that the court finds to have been unconscionable at the time it was made, unconscionable in performance or contrary to public policy;

(d) any provision purporting to (i) exclude conflict of law principles under any law or (ii) select certain courts as the venue, or establish a particular jurisdiction as the forum, for the adjudication of any controversy;

(e) judicial decisions, that may permit the introduction of extrinsic evidence to modify the terms or the interpretation of any agreement;

(f) the tax or accounting consequences of any transaction contemplated in connection with the sale of the Securities under applicable tax laws and regulations and under applicable accounting rules, regulations, releases, statements, interpretations or technical bulletins;

(g) applicable antifraud statutes, rules or regulations of United States federal or applicable state laws concerning the issuance or sale of securities, including, without limitation, (i) the accuracy and completeness of the information provided by the Company to the Investors in connection with the offer and sale of the Securities, and (ii) the accuracy or fairness of the past, present or future fair market value of any securities;

(h) the effect any breach of the fiduciary duties of the members of the Company's Board of Directors, officers or principal stockholders would have on the enforceability authorization and performance of any agreement;

(i) whether or not any Transaction Document, and the transactions provided for therein, were fair and reasonable to the Company at the time of their authorization by the Company's Board of Directors and stockholders within the meaning of Section 144 of the DGCL;

(j) any provisions stating that (i) rights or remedies are not exclusive, (ii) rights or remedies may be exercised without notice, (iii) every right or remedy is cumulative and may be exercised in addition to or with any other right or remedy or (iv) the failure to exercise, or any delay in exercising, rights or remedies available under an agreement will not operate as a waiver of any such right or remedy;

(k) provisions stating that rights set forth in the agreement in which such provision appears may only be waived in writing if an implied agreement by trade practice or course of conduct has given rise to a waiver or that limit the effect of waivers by trade practice or course of conduct;

(l) any United States federal or other antitrust laws, statutes, rules or regulations, including without limitation the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, or other laws relating to collusive or unfair trade practices or designed to promote competition in any jurisdiction;

(m) any provision purporting to (i) waive rights to trial by jury, service of process or objections to the laying of venue or forum in connection with any litigation arising out of or pertaining to the agreement in which such provision appears, (ii) change or waive the rules of evidence, make determinations conclusive or fix the method or quantum of proof or (iii) waive the statute of limitations;

(n) any choice of law clause, to the extent the provision to be governed by that law could be determined by the court (i) to be contrary to a public or fundamental policy of a state or country whose law would apply in the absence of a choice of law clause, and (ii) to involve an issue in which such state or country, or California State, has a materially greater interest in the determination of the particular issue than does the state whose law is chosen;

(o) any United States federal laws, statutes, rules or regulations, including without limitation the International Investment and Trade in Services Survey Act (Title 22 of the United States Code, Chapter 46, §§3101-3108), or other state or foreign investment laws, statutes, rules and regulations governing investments in the United States or in U.S. entities by persons that are not citizens of the United States; and

(p) indemnification and contribution provisions to the extent enforcement of such provisions is contrary to public policy, indemnify a party to a contract against such party’s actions taken in bad faith or that constitute a breach of fiduciary duties, or indemnify a party against liability for future conduct or the party’s own fraud or wrongful, reckless or negligent acts or omissions.

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.

(3) All corporate action has been taken on the part of the Company's Board of Directors and stockholders that (a) is necessary for the execution and delivery of the Transaction Documents (other than the Voting Agreement as to which we render no opinion) by the Company, (b) must be taken by the Company to authorize the sale and issuance of the Securities on the date hereof, and (c) must be taken by the Company as of the date hereof to authorize performance by the Company of its obligations under the Transaction Documents.

(4) Each of the Transaction Documents has been duly executed by the Company and has been delivered by the Company to the Investors. Each of the Transaction Documents constitutes a valid and binding obligation of the Company, enforceable by you against the Company in accordance with its terms.

(5) The Shares to be issued to you under the Purchase Agreement, and the Warrant Shares are duly authorized, and when issued in compliance with the provisions of the Purchase Agreement, will be validly issued, fully paid and non-assessable, and the issuance of such Shares and Warrant Shares will not be subject to any preemptive rights, rights of first refusal or rights of first offer set forth in the Restated Certificate or Bylaws or any Reviewed Agreement set forth on Exhibit A (other than the Side Letter and the 2013 Securities Agreement, for which appropriate waivers have been obtained).

(6) The execution, delivery and performance of the Transaction Documents by the Company do not, as of the Closing, result in (a) a violation by the Company of the Restated Certificate or Bylaws, (b) a violation by the Company of any judgment or order of any court or governmental authority, (c) a violation by the Company of Applicable Law or (d) a material breach of, or a default under, any Reviewed Agreements set forth on Exhibit A.

(7) Other than those that previously may have been obtained or made, no consent, approval or authorization of, or filing with, any governmental authority pursuant to any Applicable Law is required to be made or obtained by the Company or any subsidiary of the Company in connection with the Company's (a) valid execution and delivery of the Transaction Documents, (b) performance of its obligations under the Purchase Agreement on the date hereof and (c) performance of its obligations under the other Transaction Documents as of the date hereof.

(8) Based in part upon the representations made by you in the Purchase Agreement, and subject to the filings of such securities law notices as may be required to be filed

to the Closing, the offer, sale and issuance of the Shares to be issued to you in conformity with the terms of the Purchase Agreement constitute transactions exempt from the registration requirements of Section 5 of the Securities Act of 1933, as amended, and exempt from the qualification requirements of Section 25110 of the California Corporate Securities Law of 1968, as amended.

(9) Based in part upon the representations made by you in the Purchase Agreement, and subject to the filings of such securities law notices as may be required to be filed subsequent to the Closing, the offer, sale and issuance of the Warrants and (assuming the Warrants were exercised on the date hereof) the issuance to you of the Warrant Shares, constitute transactions exempt from the registration requirements of Section 5 of the Securities Act of 1933, as amended, and exempt from the qualification requirements of Section 25110 of the California Corporate Securities Law of 1968, as amended.

(10) The Company is not and, after giving effect to the offering and sale of the Securities, will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

In addition to the foregoing opinions, based upon the foregoing and other than as set forth in the Purchase Agreement, we supplementally confirm the following to you as of immediately prior to the Closing.

Litigation Confirmation. To our knowledge, there is no action, suit, proceeding or investigation by or before any United States federal, California State or Delaware State court or governmental authority that is pending or threatened in writing against the Company and that questions the validity of the Transaction Documents or the right of the Company to enter into and perform its obligations under the Transaction Documents. Please note that we have not conducted a docket search in any jurisdiction with respect to any action, suit, proceeding or investigation that may be pending against the Company and we have not undertaken any search regarding any of its affiliates, officers or directors, nor, other than to request the Opinion Certificate from the Company, have we undertaken any further inquiry whatsoever in connection with the existence any such action, suit, proceeding or investigation.
