In the event that the Transfer is being made pursuant to the provisions of Section 3.1, the Notice shall state under which clause of Section 3.1 the Transfer is being made.

2.2 Company Right of First Refusal.

(a) For a period of twenty (20) days following receipt of any Notice described in Section 2.1, the Company shall have the right to purchase all or a portion of the Key Employee Stock subject to such Notice on the same terms and conditions as set forth therein (the “Company Right of First Refusal”). The Company’s purchase right shall be exercised by written notice signed by an officer of the Company (the “Purchase Notice”) and delivered to the Key Employee within such twenty (20) day period. The Company shall effect the purchase of the Key Employee Stock, including payment of the purchase price, not more than five (5) business

days after delivery of the Purchase Notice, and at such time the Key Employee shall deliver to the Company the certificate(s) representing the Key Employee Stock to be purchased by the Company, each certificate to be properly endorsed for transfer. The Key Employee Stock so purchased shall thereupon, be cancelled and cease to be issued and outstanding shares of the Company’s Common Stock.

(b) In the event that the Company does not elect to purchase all of the Key Employee Stock available pursuant to its rights under Section 2.2 within the period set forth therein, the Key Employee shall promptly give written notice (the “Second Notice”) to each of the Investors, which shall set forth the number of shares of Key Employee Stock not purchased by the Company. Each Investor shall then have the right, exercisable upon written notice to the Key Employee (the “Investor Notice”) within ten (10) days after the receipt of the Second Notice, to purchase its pro rata share of the Key Employee Stock subject to the Second Notice and on the same terms and conditions as set forth therein. Except as set forth in Section 2.2(d), the Investors who so exercise their rights (the “Participating Investors”) shall effect the purchase of the Key Employee Stock, including payment of the purchase price, not more than five (5) days after delivery of the Investor Notice, and at such time the Key Employee shall deliver to the Participating Investors the certificate(s) representing the Key Employee Stock to be purchased by the Participating Investors, each certificate to be properly endorsed for transfer.

(c) Each Investor’s pro rata share shall be equal to the product obtained by multiplying (i) the aggregate number of shares of Key Employee Stock covered by the Second Notice and (ii) a fraction, the numerator of which is the number of shares of Common Stock issued or issuable upon the conversion or exercise of Preferred Stock or other rights to acquire shares of Common Stock held by the Participating Investor at the time of the Notice, and the denominator of which is the total number of shares of Common Stock issued or issuable upon the conversion or exercise of Preferred Stock or other rights to acquire shares of Common Stock at the time of the Notice held by all Investors.

(d) In the event that not all of the Investors elect to purchase their pro rata share of the Key Employee Stock available pursuant to their rights under Section 2.2(b) within the time period set forth therein, then the Key Employee shall promptly give written notice to each of the Participating Investors (the “Overallotment Notice”), which shall set forth the number of shares of Key Employee Stock not purchased by the other Investors, and shall offer such Participating Investors the right to acquire such unsubscribed shares. Each Participating Investor shall have five (5) days after receipt of the Overallotment Notice to deliver a written notice to the Key Employee (the “Participating Investors Overallotment Notice”) indicating the number of unsubscribed shares that such Participating Investor desires to purchase, and each such Participating Investor shall be entitled to purchase such number of unsubscribed shares on the same terms and conditions as set forth in the Second Notice. In the event that the Participating Investors desire, in the aggregate, to purchase in excess of the total number of available unsubscribed shares, then the number of unsubscribed shares that each Participating Investor may purchase shall be reduced on a pro rata basis. For purposes of this Section 2.2(d) the denominator described in clause (ii) of subsection 2.2(c) above shall be the total number of shares of Common Stock issued or issuable upon the conversion or exercise of Preferred Stock or other rights to acquire shares of Common Stock held by all the Participating Investors at the time of the Notice. The Participating Investors shall then effect the purchase of the Key

Employee Stock, including payment of the purchase price, not more than five (5) days after delivery of the Participating Investors Overallotment Notice, and at such time, the Key Employee shall deliver to the Investors the certificates representing the Key Employee Stock to be purchased by the Participating Investors, each certificate to be properly endorsed for transfer.

2.3 Right of Co-Sale.

(a) In the event the Company or its assignee(s) fail to exercise its right to purchase all of the Key Employee Stock subject to Section 2.2 hereof, following the exercise or expiration of the rights of purchase set forth in Section 2.2, then the Key Employee shall deliver to the Company and each Investor written notice (the “Co-Sale Notice”) that each Investor shall have the right, exercisable upon written notice to such Key Employee with a copy to the Company within fifteen (15) days after receipt of the Co-Sale Notice, to participate in such Transfer of Key Employee Stock on the same terms and conditions. Such notice shall indicate the number of shares of Investor Stock up to that number of shares determined under Section 2.3(b) such Investor wishes to sell under his or her right to participate. To the extent one or more of the Investors exercise such right of participation in accordance with the terms and conditions set forth below, the number of shares of Key Employee Stock that such Key Employee may sell in the transaction shall be correspondingly reduced.

(b) Each Investor may sell all or any part of that number of shares equal to the product obtained by multiplying (i) the aggregate number of shares of Key Employee Stock covered by the Co-Sale Notice and not purchased by the Company or its assignees pursuant to Section 2.2 by (ii) a fraction, the numerator of which is the number of shares of Common Stock owned by such Investor at the time of the Co-Sale Notice and the denominator of which is the total number of shares of Common Stock, in the aggregate, owned by such Key Employee (excluding shares purchased by the Company and/or its assignee(s) pursuant to Section 2.2) and the Investors at the time of the Co-Sale Notice. If not all of the Investors elect to sell their share of Common Stock proposed to be transferred within said fifteen (15) day period, then the Key Employee shall promptly notify in writing the Investors who do so elect and shall offer such Investors the additional right to participate in the sale of such additional shares of Key Employee Stock proposed to be transferred on the same percentage basis as set forth above in this Section 2.3(b). The Investors shall have five (5) days after receipt of such notice to notify the Key Employee in writing, with a copy to the Company, of its election to sell all or a portion of the unsubscribed shares.

(c) Each Investor that elects to participate in the Transfer pursuant to this Section 2 (a “Co-Sale Participant”) shall effect its participation in the Transfer by promptly delivering to such Key Employee for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent:

(i) the type and number of shares of Common Stock which such Co-Sale Participant elects to sell; or

(ii) that number of shares of Preferred Stock which is at such time convertible into the number of shares of Common Stock which such Co-Sale Participant elects to sell; provided, however, that if the prospective purchaser objects to the delivery of Preferred

Stock in lieu of Common Stock, such Co-Sale Participant shall convert such Preferred Stock into Common Stock and deliver Common Stock as provided in Section 2.3(c)(i) above. The Company agrees to make any such conversion concurrent with and contingent upon the actual transfer of such shares to the purchaser.

(d) The stock certificate or certificates that the Co-Sale Participant delivers to such Key Employee pursuant to Section 2.3(c) shall be transferred to the prospective purchaser in consummation of the sale of the Common Stock pursuant to the terms and conditions specified in the Co-Sale Notice, and the Key Employee shall concurrently therewith remit to such Co-Sale Participant that portion of the sale proceeds to which such Co-Sale Participant is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibit such assignment or otherwise refuse to purchase shares or other securities from a Co-Sale Participant exercising its rights of co-sale hereunder, such Key Employee shall not sell to such prospective purchaser or purchasers any Key Employee Stock unless and until, simultaneously with such sale, such Key Employee shall purchase such shares or other securities from such Co-Sale Participant on the same terms and conditions specified in the Co-Sale Notice.

(e) The exercise or non-exercise of the rights of any Investor hereunder to participate in one or more Transfers of Key Employee Stock made by any Key Employee shall not adversely affect his right to participate in subsequent Transfers of Key Employee Stock subject to this Section 2.

(f) To the extent that the Investors do not elect to participate in the sale of the Key Employee Stock subject to the Co-Sale Notice, such Key Employee may, not later than sixty (60) days following delivery to the Company of the Co-Sale Notice, enter into an agreement providing for the closing of the Transfer of such Key Employee Stock covered by the Co-Sale Notice within thirty (30) days of such agreement on terms and conditions not materially more favorable to the transferor than those described in the Co-Sale Notice. Any proposed Transfer on terms and conditions materially more favorable than those described in the Co-Sale Notice, as well as any subsequent proposed Transfer of any of the Key Employee Stock by a Key Employee, shall again be subject to the first refusal and co-sale rights of the Company and/or Investors and shall require compliance by a Key Employee with the procedures described in this Section 2.

3.	EXEMPT TRANSFERS.

3.1 Notwithstanding the foregoing, the first refusal and co-sale rights of the Company and/or the Investors set forth in Section 2 above shall not apply to any transfer without consideration to (i) the Key Employee’s spouse, children, parents or siblings (collectively, “Family Members”), (ii) any trust or for estate planning purposes solely for the benefit of such Key Employee and/or Family Member(s) and of which such Key Employee and/or any such Family Member(s) is the trustee or are the trustees, and (iii) any partnership, corporation or limited liability company that is wholly owned and controlled by such Key Employee and/or any such Family Member(s), provided that (A) the Key Employee shall inform the Investors of such transfer prior to effecting it and (B) the transferee shall enter into a written agreement to be bound by and comply with all provisions of this Agreement, as if it were an original Key Employee hereunder, including without limitation Section 2. Such transferred Key Employee

Stock shall remain “Key Employee Stock” hereunder, and such transferee shall be treated as the “Key Employee” for purposes of this Agreement.

3.2 Notwithstanding the foregoing, the provisions of Section 2 shall not apply to the sale of any Key Employee Stock to the public pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”).

3.3 This Agreement is subject to, and shall in no manner limit the right which the Company may have to repurchase securities from the Key Employee pursuant to (i) a stock restriction agreement or other agreement between the Company and the Key Employee and (ii) any right of first refusal set forth in any agreement between the Company and the Key Employees regarding the repurchase of Common Stock of the Company.

4.	PROHIBITED TRANSFERS.

4.1 Put Option.

(a) In the event that a Key Employee should sell any Key Employee Stock in contravention of the co-sale rights of each Investor under Section 2.3 of this Agreement (a “Prohibited Transfer”), each Investor, in addition to such other remedies as may be available at law, in equity or hereunder, shall have the put option provided below, and such Key Employee shall be bound by the applicable provisions of such option.

(b) In the event of a Prohibited Transfer, each Investor shall have the right to sell to such Key Employee the type and number of shares of Common Stock equal to the number of shares each Investor would have been entitled to transfer to the purchaser under Section 2.3 hereof had the Prohibited Transfer been effected pursuant to and in compliance with the terms hereof. Such sale shall be made on the following terms and conditions:

(i) The price per share at which the shares are to be sold to the Key Employee shall be equal to the price per share paid by the purchaser to such Key Employee in such Prohibited Transfer. The Key Employee shall also reimburse each Investor for any and all fees and expenses, including legal fees and expenses, incurred in connection with the exercise or the attempted exercise of the Investor’s rights under Section 2.3.

(ii) Within ninety (90) days after the date on which an Investor receives notice of the Prohibited Transfer, such Investor shall, if exercising the option created hereby, deliver to the Key Employee the certificate or certificates representing the shares to be sold, each certificate to be properly endorsed for transfer.

(iii) Such Key Employee shall, upon receipt of the certificate or certificates for the shares to be sold by an Investor, pursuant to this Section 4.1, pay the aggregate purchase price therefor and the amount of reimbursable fees and expenses, as specified in Section 4.1(b)(i), in cash or by other means acceptable to the Investor.

4.2 Voidability of Transfer. Notwithstanding the foregoing, any purported Transfer by a Key Employee of Key Employee Stock in violation of Section 2 and/or Section 3 hereof

shall be voidable at the option of the holders of a majority of the Investor Stock if the Investors do not elect to exercise the call or put option set forth in this Section 4, and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee as the holder of such shares without the written consent of the holders of a majority of the Investor Stock.

LEGEND.

5.1 Each certificate representing shares of Key Employee Stock now or hereafter owned by the Key Employee or issued to any person in connection with a Transfer pursuant to Section 3.1 hereof shall be endorsed with the following legend:

“THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT BY AND AMONG THE STOCKHOLDER, THE COMPANY AND CERTAIN HOLDERS OF STOCK OF THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.”

5.2 The Key Employees agree that the Company may instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the legend referred to in Section 5.1 above to enforce the provisions of this Agreement and the Company agrees to promptly do so. The legend shall be removed at the request of any Key Employee following termination of this Agreement.

6.	MISCELLANEOUS.

6.1 Conditions to Exercise of Rights. Exercise of the Investors’ rights under this Agreement shall be subject to and conditioned upon, and the Key Employees and the Company shall use their best efforts to assist each Investor in, compliance with applicable laws.

6.2 Governing Law. This Agreement shall be governed by and construed under the laws of the State of California in all respects as applied to agreements among California residents entered into and performed entirely within California. The parties agree that any action brought by either party under or in relation to this Agreement, including without limitation to interpret or enforce any provision of this Agreement, shall be brought in, and each party agrees to and does hereby submit to the jurisdiction and venue of, any state or federal court located in the County of Santa Clara, California.

6.3 Amendment. Any provision of this Agreement may be amended or modified and/or the observance thereof may be waived or this Agreement terminated, only with the written consent of (i) the Company, (ii) as to the Investors, persons holding a majority in interest of the Common Stock issued or issuable upon (a) the conversion or exercise of Preferred Stock, (b) the exercise of up to 166,367 warrants to purchase shares of Preferred Stock (on an as-converted to Common Stock basis) issued to entities associated with Advanced Equities Financing Corp. and its assignees, pursuant to Section 6.4 hereof, and (c) the settlement of up to 176,272 restricted stock units and exercise of up to 60,000 options to purchase shares of

Common Stock issued to Lit Tele LLC and its assignees, pursuant to Section 6.4 hereof, and (iii) as to the Key Employees, a majority in interest of the Key Employee Stock held by Key Employees then providing services to the Company as officers, employees or consultants; provided, that no consent of any Key Employee shall be necessary for any amendment and/or restatement which merely includes additional holders of Preferred Stock or other preferred stock of the Company as “Investors” as parties hereto or other employees of the Company as “Key Employees” and parties hereto and does not materially increase such Key Employees’ obligations hereunder other than the increase in the number of shares determined by Section 2.3 hereof as a result of the addition of such additional holder; provided, further, that for any amendment or waiver of any provision herein that would have a material, adverse and disproportionate effect on a series of Preferred Stock relative to any other series of Preferred Stock, consent of the holders of at least a majority of such series of Preferred Stock voting as a separate class. Any amendment or waiver effected in accordance with clauses (i), (ii), and (iii) of this Section 6.3 shall be binding upon each Investor, its successors and assigns, the Company and each of the Key Employees.

6.4 Successors and Assigns. The provisions hereof shall inure to the benefit of, and be binding upon, the parties hereto and their respective successors, assigns, heirs, executors and administrators and other legal representatives.

6.5 Term. This Agreement shall continue in full force and effect from the date hereof through the earliest of the date of the closing of Liquidation or Qualified IPO, each as defined in the Company’s Amended and Restated Articles of Incorporation, as amended from time to time, on which date it shall terminate in its entirety.

6.6 Ownership. The Key Employees represent and warrant that each is the sole legal and beneficial owner of those shares of Key Employee Stock he or she currently holds subject to the Agreement and that no other person has any interest (other than a community property interest) in such shares.

6.8 Severability. In the event one or more of the provisions of this Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

6.9 Aggregation of Stock. All shares of Preferred Stock held or acquired by affiliated entities or persons shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

6.10 Attorneys’ Fees. In the event that any suit or action is instituted under or in relation to this Agreement, including without limitation to enforce any provision in this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals.

6.11 Entire Agreement. This Agreement and the Exhibits hereto, along with the Purchase Agreement and the other documents delivered pursuant thereto, constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof and no party shall be liable or bound to any other in any manner by any oral or written representations, warranties, covenants or agreements except as specifically set forth herein and therein. Each party expressly represents and warrants that it is not relying on any oral or written representations, warranties, covenants or agreements outside of this Agreement.

6.12 Counterparts. This Agreement may be executed in two or more counterparts, including counterparts transmitted by facsimile, other electronic transmission or otherwise, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

6.13 Previous Agreement. The Previous Agreement is hereby amended and superseded in its entirety and restated herein. Such amendment and restatement is effective upon execution and delivery of this Agreement by the Company and by the requisite holders as set forth in Section 6.3 of the Previous Agreement. Upon such execution, all provisions of, rights granted and covenants made in the Previous Agreement are hereby waived, released and superseded in their entirety and shall have no further force or effect.

(b) The Company and the Investors agree that they shall not enter into any agreement, amend any existing agreement or otherwise adopt a provision that would require Total G&P to vote or otherwise take any action related to a Voting Transaction.

6. No Liability for Election of Recommended Directors. None of the Company, the Common Holders or the Investors, nor any officer, director, stockholder, partner, employee or agent of such party, if any, makes any representation or warranty as to the fitness or competence of the nominee of any party hereunder to serve on the Company’s Board of

Directors by virtue of such party’s execution of this Agreement or by the act of such party in voting for such nominee pursuant to this Agreement.

7. Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured party for the breach of this Agreement by any party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order without a requirement of posting bond. Further, each party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach.

(a) The provisions of this Agreement shall be binding upon the successors in interest to any securities of the Company held by any party to this Agreement and their successors and assigns.

(b) Each certificate representing each of the securities shall bear a legend reading as follows:

“THE SHARES EVIDENCED HEREBY ARE SUBJECT TO THE TERMS OF A VOTING AGREEMENT (A COPY OF WHICH MAY BE OBTAINED WITHOUT CHARGE FROM THE COMPANY), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF THE VOTING AGREEMENT.”

10. Execution by the Company. The Company, by its execution in the space provided below, agrees that it will cause the certificates evidencing the shares of capital stock subject to this Agreement to bear the legend required by paragraph 9 hereof and will not permit such legend to be removed, and it shall supply, free of charge, a copy of this Agreement to any

holder of a certificate evidencing shares of capital stock of the Company upon written request from such holder to the Company at its principal office. If at any time or from time to time any Common Holder or Investor holds any certificate representing shares of the Company’s capital stock not bearing the legend required by paragraph 9, such Common Holder or Investor agrees to deliver such certificate to the Company promptly to have such legend placed on such certificate. The parties hereto do hereby agree that the failure to cause the certificates evidencing the shares of capital stock subject to this Agreement to bear the legend required by paragraph 9 hereof and/or failure of the Company to supply, free of charge, a copy of this Agreement as provided under this paragraph 10 shall not affect the validity or enforcement of this Agreement.

11. Term. This Agreement shall be effective as of the date hereof and shall continue in effect until and shall terminate upon the earliest to occur of (i) the consummation of the first underwritten public offering of the Company’s Common Stock pursuant to a registration statement under the Securities Act of 1933, as amended, pursuant to which all outstanding shares of Preferred Stock convert into Common Stock, (ii) the consummation of a Merger Transaction (as such term is defined in the this Agreement, as amended from time to time), or (iii) termination of this Agreement in accordance with Section 13(d) hereof.

12. Grant of Proxy.

The proxy and power, so long as any party hereto is an individual, will survive death, incompetency and disability of such party or any other individual holder of the shares of capital stock and, so long as any party hereto is an entity, will survive the merger or reorganization of such party.

13. Miscellaneous

Total Gas & Power USA, SAS

Ladies and Gentlemen:

We have acted as counsel for Amyris, Inc., a Delaware corporation (the “Company”), in connection with the sale by the Company to you (“you” or “Purchaser”) of 7,101,548 shares of the Company’s Series D Preferred Stock (the “Shares”) pursuant to the Series D Preferred Stock Purchase Agreement, dated as of June 21, 2010 (the “Purchase Agreement”), between the Company and Purchaser, and the execution and delivery by the Company of the Amended and Restated Investors’ Rights Agreement (the “Rights Agreement”), the Amended and Restated Right of First Refusal and Co-Sale Agreement (the “Co-Sale Agreement”) and the Amended and Restated Voting Agreement (the “Voting Agreement”), each dated June 21, 2010. This opinion is given to you pursuant to Section 4.9 of the Purchase Agreement in connection with the Closing of the sale of the Shares. The Purchase Agreement, the Rights Agreement, the Co-Sale Agreement and the Voting Agreement are referred to herein collectively as the “Transaction Documents.” Unless defined herein, capitalized terms have the meaning given them in the Purchase Agreement.

In rendering this opinion, we have examined such matters of law as we 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 (the “Opinion Certificate”). In addition, we have examined originals or copies of documents, corporate records and other writings that we consider relevant for the purposes of this opinion. 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 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

To Total Gas & Power USA, SAS

on the date hereof

Page 2

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 Purchaser 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, that would modify or interpret the terms of the Transaction Documents 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 (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.

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

To Total Gas & Power USA, SAS

on the date hereof

Page 3

as it is presently conducted, as to the types of businesses the Company presently conducts, we have relied exclusively upon representations made to us in the Opinion Certificate.

With respect to the opinion rendered in paragraph (3) (Capitalization) below relating to the Company’s authorized, issued and outstanding capital stock and the confirmation as to Preemptive and Other Rights that follows our opinions, please note that we have not maintained any of the Company’s stock records. Such records have been maintained by the Company and its former counsel, either directly or through eProsper, a third party service, until we began representing the Company during October 2008 and we have not had any knowledge of the procedures used by the Company and its former counsel for issuing and transferring the Company’s securities. Accordingly, in rendering the opinion set forth in paragraph (3) and in the Preemptive and Other Rights Confirmation, we have relied without further investigation on (a) the Company’s Restated Certificate of Incorporation certified by the Delaware Secretary of State on June 18, 2010 (the “Restated Certificate”), (b) the bylaws of the Company certified by the Secretary of the Company on June 21, 2010 (the “Bylaws”), (c) minute books relating to meetings and written actions of the incorporator(s), Board of Directors and stockholders of the Company, (d) stock ledger, certificate books, stock holder list, list of options, list of warrants and lists of stock purchase rights that have been maintained by the Company and its former counsel or eProsper prior to our representation and that are now maintained by us and eProsper in the course of our representation based upon information received by us from the Company, and (e) statements in the Opinion Certificate relating to the equity capitalization of the Company (collectively, the “Capitalization Records”). We do not have the information necessary to verify the accuracy and completeness of the information on the number and type of securities outstanding, other than by reviewing the Capitalization Records. Accordingly, our opinion on, and confirmation of, the number and type of issued and outstanding securities means that, based upon the examination referred to above, the Capitalization Records are consistent with the information as to the number and type of outstanding stock, options, warrants, conversion privileges or other rights that is set forth in paragraph (3) and in such confirmation.

In connection with our opinion set forth in paragraph (3) (Capitalization) and in the Preemptive and Other Rights Confirmation that follows our opinions, we have relied without independent verification on the Opinion Certificate, to the effect that the Company has received the consideration approved by its Board of Directors for all of the issued shares of capital stock of the Company.

We note that the parties to the Purchase Agreement and the Voting Agreement (together, the “Delaware Agreements”) have designated the laws of the State of Delaware as the laws governing the Delaware Agreements. We are not licensed to practice law in the State of Delaware. As a result, notwithstanding the designation therein of the laws of the State of Delaware, our opinion in paragraph (5) (Enforceability) below as to the validity, binding effect and enforceability of the Delaware Agreements 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

To Total Gas & Power USA, SAS

on the date hereof

Page 4

contracts made between California residents present in California when the Delaware Agreements are entered into (without regard to laws regarding choice of law or conflict of laws).

In rendering the opinion in paragraph (7) (No Violations) below relating to violations of Applicable Laws, and paragraph (8) (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 (5) (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 paragraph (9) (Securities Law Compliance) below.

In rendering the opinion expressed in paragraph (9) (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. We have relied upon the Company’s representation that it had a pre-existing substantive business relationship with you prior to the filing of the Form S-1 Registration Statement filed by the Company with the Securities and Exchange Commission on April 16, 2010, as amended (together the “Registration Statement”) and that the filing of the Registration Statement did not cause you to seek to purchase the Shares. Furthermore, we have assumed the accuracy of, and have relied upon, your representation that you are a “qualified institutional buyer” within the meaning of Rule 144A of the Securities Act of 1933, as amended. In addition, we are rendering no opinion as to whether the Company’s press release titled “Amyris Secures Funding to Advance Scale Up, First Commercial Plan” dated October 1, 2009 constituted a general solicitation or publication of any advertisement in connection with the Company’s issuance and sale of any of its securities, nor the effect such press release had on any offerings of its securities. We have assumed for the purposes of this opinion that such press release did not constitute a general solicitation nor publication of any advertisement within the meaning of the securities laws referred to in paragraph (9)

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 conveyances, 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

To Total Gas & Power USA, SAS

on the date hereof

Page 5

the implied covenant of good faith and fair dealing, or would be commercially unreasonable or involve undue delay, whether or not such principles or decisions have been codified by statute;

(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 Shares 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 Purchaser in connection with the offer and sale of the Shares, 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 agreement, 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 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;

(k) 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

To Total Gas & Power USA, SAS

on the date hereof

Page 6

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 (iii) limit the effect of waivers by trade practice or course of conduct or (iv) waive the statute of limitations;

(l) 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;

(m) indemnification and contribution provisions to the extent enforcement of such provisions are contrary to public policy or indemnify a party against liability for future conduct or the party’s own fraud or wrongful, reckless or negligent acts or omissions;

(n) any provisions imposing obligations to vote the Company’s capital stock in a certain manner, or any drag-along provision, including without limitation those provisions set forth in the Voting Agreement, due to (i) the application of equitable principles in connection with any remedy sought to enforce such provisions, irrespective of whether the remedies sought are legal or equitable in nature, (ii) the application of general legal principles requiring that waivers of rights be knowing and intelligent, and with knowledge of consequences of the waiver, and (iii) conflict with the provisions of the DGCL requiring that votes be counted as cast, rather than in accordance with such voting or drag-along terms and conditions, and the extent to which a corporation can take action to enforce such terms and conditions; and

(o) any provision concerning the obligation of the Company (or its underwriters or agents) to sell shares of stock to certain persons or entities in connection with a public offering, including but not limited to the provisions of the right of first offer set forth in Section 2.4 of the Investors’ Rights Agreement entitling Purchaser to acquire certain shares in a public offering other than a firm commitment underwritten public offering of the Company’s securities pursuant to which all outstanding shares of Preferred Stock automatically convert into Common Stock.

In connection with an opinion rendered herein that is dependent upon the validity of the Company’s certificate of incorporation, we render no opinion as to whether or not all shares of any one class of the Company’s capital stock has the same voting, conversion and redemption rights and other rights, preferences, privileges and restrictions, unless the class is divided into series, nor, if divided into series, that each such series has the same voting, conversion and redemption rights and other rights, preferences, privileges and restrictions.

as of the date hereof in accordance with the Restated Certificate, such Common Stock will be duly authorized, validly issued, fully paid and nonassessable.

(7) The execution, delivery and performance of the Transaction Documents do not, as of the Closing, result in (a) a violation of the Restated Certificate or Bylaws, (b) a material violation of any judgment or order of any court or governmental entity that is specifically identified on the Disclosure Schedule, if any, or (c) a material violation of any Applicable Law.

Dear Sirs and Mesdames:

The undersigned understands that Xxxxxx Xxxxxxx & Co. Incorporated (“Xxxxxx Xxxxxxx”) and Xxxxxxx, Sachs & Co. (“Xxxxxxx, Xxxxx” and together with Xxxxxx Xxxxxxx, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Amyris Biotechnologies, Inc., a California corporation (together with any successor thereto, the “Company”), providing for the public offering (the “Public Offering”) by the several underwriters, including the Representatives (the “Underwriters”), of shares (the “Shares”) of the Common Stock, no par value per share, of the Company (the “Common Stock”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Lock-Up Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or (3) publicly announce the intent to do any of the foregoing. The foregoing sentence shall not apply to:

(a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under the Exchange Act (other than a filing on a Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A) made after the expiration of the Lock-Up Period), shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions;

(b) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock as a bona fide gift;

(c) distributions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to limited partners, members or stockholders of the undersigned;

(d) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock by will or intestate succession or to any trust or partnership for the direct or indirect benefit of such person or any member of the immediate family of the undersigned;

(e) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, provided that the undersigned shall not engage in any transaction under such trading plan until the termination of the Lock-Up Period;

(f) the exercise of options, warrants or rights to acquire shares of Common Stock or any security convertible into Common Stock, in each case outstanding on the date hereof, in accordance with their terms, provided that the acquired Common Stock is subject to the same terms of the Lock-Up Period;

(g) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to the Company, pursuant to agreements under which the Company has the option to repurchase such shares or a right of first refusal with respect to transfers of such shares, provided that such transfers after the date of the Prospectus shall be for less than market value of the Common Stock at the time of transfer;

(h) the sale of shares of Common Stock to the Underwriters; and

(i) in the case of a non-natural person, transfers of shares of Common Stock to any wholly-owned subsidiary of the undersigned (including any corporation, partnership, limited liability company or other entity that is directly or indirectly owned by the undersigned) or to the parent corporation of the undersigned or any wholly owned subsidiary of such parent corporation;

provided that in the case of any transfer or distribution pursuant to clauses (b), (c), (d) and (i), (1) each donee, distributee or transferee shall sign and deliver a lock-up letter substantially in the form of this letter, (2) no filing under the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period, (3) such transfer or distribution shall not be a disposition for value and (4) each party (transferor, transferee, donor or donee) shall not be required by law (including without limitation the disclosure requirements of the Exchange Act) to make, and shall agree to not voluntarily make, any public announcement of the transfer or disposition (other than a filing on a Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A) made after the expiration of the Lock-Up Period). In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the

Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

If:

(1) during the last 17 days of the Lock-Up Period the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period;

the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the initial Lock-Up Period unless the undersigned requests and receives prior written confirmation from the Company or the Representatives that the restrictions imposed by this agreement have expired.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. This Lock-Up Agreement shall automatically terminate upon the earliest to occur, if any, of (a) the date the Company advises the Representatives, in writing, prior to the execution of the Underwriting Agreement, that it has determined not to proceed with the Public Offering, (b) the date of the termination of the Underwriting Agreement if prior to the closing of the Public Offering or (c) December 31, 2010 if, and only if, the Public Offering of the Shares has not been completed by such date.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.


Very truly yours,
