(c)	the Renewable Diesel Product shall cease to be a “Product” for the purposes of Article 3 of the Agreement.


9.	AMYRIS Included IP.

A. AMYRIS Farnesene Included IP and AMYRIS Hydrogenation IP as listed in Exhibit A shall be considered included in the AMYRIS Included IP pursuant to Section 6.1(c) of the Agreement (without the need for the procedures set forth therein) solely for the Renewable Diesel Development Project for all purposes under the Agreement, except as otherwise provided in this First Amendment. Any other Background IP or Non-Collaboration IP that is Controlled by AMYRIS or its Affiliates may be introduced as AMYRIS Included IP as per the Agreement.

B. Notwithstanding the scope of the licenses otherwise granted or to be granted to the JV Company under the Agreement, including Section 6.6(a) of the Agreement, the license to be granted by AMYRIS to the JV Company for Farnesene Renewable Diesel Product under its interest in the Farnesene Production IP and AMYRIS Hydrogenation IP shall be limited to: (i) an exclusive license to Make and Sell Farnesene Renewable Diesel Product manufactured using the Commercial Farnesene Strain for the Farnesene Renewable Diesel Product (but not farnesene itself, with respect to which the JV Company shall be granted only the Biofene License as mentioned in Section 9B(ii)), and (ii) a non-exclusive license to Manufacture farnesene (such non-exclusive license, the “Biofene License”) using the Commercial Farnesene Strain for the Farnesene Renewable Diesel Product solely for (A) the purpose of Manufacturing the Farnesene Renewable Diesel Product from such farnesene and (B) such other purposes as are mutually agreed by AMYRIS and TOTAL in writing, in each case (i) and (ii), in accordance with such license and the terms governing such JV Company. The terms of the Biofene License under Farnesene Production IP shall be subject to conditions consistent with or better for the JV Company than licenses that AMYRIS and its Affiliates grant to their other partners for the manufacture of farnesene. These conditions shall include, but may not be limited to the following: (1) the JV Company will be permitted to engage in random mutagenesis but may not engage in any other Farnesene Strain engineering with respect to the Commercial Strain for the Renewable Diesel Product, (2) the JV Company will be permitted to transfer the Commercial Farnesene Strain to any contract manufacturer in accordance with the license terms between AMYRIS and the JV Company, (3) the license agreement granting the Biofene License shall include other reasonable provisions, including without limitation, reporting, audit, and inspection rights in order to protect the Farnesene Production IP and the Commercial Farnesene Strain, and (4) the JV Company shall not and shall not allow any other Person to reverse engineer any Commercial Farnesene Strain, engineer any other strain from the Commercial Farnesene Strain, use the Commercial Farnesene Strain, or distribute, disclose, or transfer the Commercial Farnesene Strain or any related AMYRIS Farnesene Included IP to any Third Party (other than a contract manufacturer as described above) in each case for any purpose other than the licensed purpose. Notwithstanding Section 9B, the financial terms of any licenses granted by XXXXXX to the JV Company shall be consistent with the content of the Cover Letter and the JV Principles.

X. XXXXXX has informed TOTAL that XXXXXX has received the following two grants from the U.S. government: (i) Scale-Up and Mobilization of Renewable Diesel & Chemical Production from Common Intermediate Using US-Based Fermentable Sugar

Feedstocks (IBR Cooperative Agreement), Award No. DE-EE0002869 (the “IBR Grant”) and (ii) Biocatalyst Development for the National Advanced Biofuels Consortium (NABC) Subcontract ZFT-0-40623-01 (the “NABC Grant”). XXXXXX has further informed TOTAL that none of the subject matter disclosed by the patents and patent applications listed in Exhibit A was funded by either the IBR Grant or the NABC Grant, and TOTAL is relying on such representation in entering into this First Amendment.

TOTAL acknowledges that it is possible that after the Amendment Effective Date, AMYRIS may file one or more patent applications comprising Farnesene Production IP, which patent applications disclose inventions generated under either the IBR Grant or the NABC Grant, thereby subjecting such patent applications and any resulting patents and their use to certain restrictions and obligations to the United States government. TOTAL acknowledges that the rights of AMYRIS, TOTAL and their respective Affiliates', and the rights of the JV Company with regard to the applicable patent applications and patents will be subject to any rights of the U.S. government or any other relevant government entity arising as a result of such grants (including march-in rights) and will be subject to any restrictions on such exploitation. In such case, the Management Committee shall agree on how to mitigate or eliminate any adverse impact on the Parties and/or the JV Company.

Before entering into any grant or contract that may provide any government or non-for profit entity any rights (e.g., rights provided to the U.S. Government under 35 U.S. 200 et seq. or any similar provisions of foreign law) to any patent application or patents resulting from work done in connection with such grant or contract that might be useful in connection with the conduct of the Renewable Diesel Development Project or to Manufacture farnesene to make Renewable Diesel Products or to Make and Sell Renewable Diesel Products, AMYRIS shall notify the Management Committee, which shall agree on how to mitigate or eliminate any adverse impact on the Parties and/or the JV Company.


10.	Limitation of Rights to Use Farnesene Production IP from Licenses. The Parties hereby agree that, notwithstanding the terms of the Agreement, the licenses granted or to be granted to TOTAL in Sections:

(i)

6.2(c), 6.3(a), 6.3(d) and 6.3(e) of the Agreement with respect to Renewable Diesel Products will not include the right for TOTAL to use Farnesene Production IP for the production of farnesene from fermentation of a Farnesene Strain and subsequent purification of farnesene to hydrogenation grade, except in each case to the extent necessary for TOTAL to exercise the Exclusive Products Sole Risk Production Right of First Refusal described in Section 11 below for Renewable Diesel Product, and


(ii)	6.3(b) will exclude the right for TOTAL to use Farnesene Production IP for further optimization of a Commercial Farnesene Strain other than by means of random mutagenesis.

The foregoing limitations in this Section 10 shall not limit or deprive TOTAL of any rights granted to TOTAL prior to execution of this First Amendment, or that may be granted to TOTAL under the Agreement with respect to (a) any Collaboration IP not made in connection with the Renewable Diesel Development Plan, or (b) with respect to any Product other than a Renewable Diesel Product.

The Parties also hereby agree that, notwithstanding the terms of Section 10.6 of the Agreement, the license grants set forth in or extended under Section 10.6.1(a) of the Agreement exclude the right for TOTAL to use Farnesene Production IP for the production of farnesene from fermentation of a Farnesene Strain and subsequent purification of farnesene to hydrogenation grade.


11.	Exclusive Products Sole Risk Production Right of First Refusal. The Parties agree that the “Production Right of First Refusal” set forth in Section 3.2(d)(i) of the Agreement shall be replaced by the following for the purpose of Exclusive JV Products:

A. The Parties agree that any JV Project may be conducted by one or both Party(ies) or its Affiliate(s) independently from one another and from the Holding JV Company, provided that the applicable Party or its Affiliate (the “Proposing Party”) shall offer to the other Party (the “Receiving Party”) an Exclusive Products Sole Risk Production Right of First Refusal” as described in this Section 11 to participate in the applicable JV Project on an equal funding basis through the Holding JV Company unless otherwise agreed by the Parties (the “Proposed Project”).

If the Receiving Party exercises this Exclusive Products Sole Risk Production Right of First Refusal with respect to a particular JV Project, then the Holding JV Company will be the vehicle for the investment of both Parties in the Proposed Project unless otherwise agreed by the Parties. The Proposing Party shall not commence a JV Project for the Exclusive JV Product except in compliance with this Section 11.

B. In the event that a Proposing Party desires to independently launch a JV Project for an Exclusive JV Product (either alone or with one or more Third Parties), it shall first provide the Receiving Party written notice containing a description of the Proposed Project and a description of the terms available to participate in the Proposed Project.

C. If within sixty (60) days of receipt of the notice described in Section 11(B) above, the Receiving Party provides notice to the Proposing Party that the Receiving Party or any of its Affiliates desires to enter into such a transaction with the Proposing Party on such terms and conditions, then the Proposing Party shall not commence the Proposed Project without the Receiving Party and/or its Affiliate and the Holding JV Company (or other applicable JV Company) entering into an agreement for the Proposed Project with the Proposing Party (which agreement may include one or more Third Parties).

D. Upon the earlier of (1) the Receiving Party providing the Proposing Party with written notice that the Receiving Party does not wish to enter into such Proposed Project through the Holding JV Company and (2) the expiration of the sixty (60) day period following the date the notice described in Section 11(B) above was provided to the Receiving Party (provided that the Receiving Party has not provided the Proposing Party with written notice that it desires to enter into such a transaction as described in Section 11(C) during such sixty (60) day period), then, subject to subsection (G) below, the Proposing Party shall thereafter be free to engage in the Proposed Project either alone or with one or more Third Parties outside the JV Company (such project, an “Independent Project”).

E. Before entering into any agreement with a Third Party with respect to any activities substantially similar to a Proposed Project on terms more favorable to the Third Party than the terms last offered to and declined by the Receiving Party with respect to the Proposed Project, the Proposing Party shall offer to the Receiving Party the opportunity to participate in such activities on the terms it intends to offer to such Third Party and the sixty (60) day

offer period (and the corresponding commitment not to commence such activities while the Receiving Party is evaluating its interest in such Proposed Project) shall commence anew.

F. If the Proposing Party elects to engage in an Independent Project, the Receiving Party and/or the Holding JV Company, as needed, shall grant to the Proposing Party on a non-exclusive basis all the licenses necessary to engage in the Independent Project under the intellectual property Controlled by the Receiving Party and/or the Holding JV Company (for clarity such licenses shall include the right to Manufacture, use and import intermediates of the Exclusive JV Product solely for the purpose of incorporating such intermediates into the Renewable Diesel JV Product and any license required to be granted by the Receiving Party shall not be required to be broader in scope than the rights granted to the Holding JV Company with respect to the applicable Exclusive JV Product and the foregoing licenses may be subject to terms and conditions analogous to those set forth in the license from the Receiving Party to the Holding JV Company). The Proposing Party shall pay the Receiving Party a royalty equal to 20% of Net Income deriving from the Independent Project. For the purpose of calculating such royalty, Net Income with respect to a unit of any Exclusive JV Products produced under the Independent Project and used by the Proposing Party or its Affiliates internally shall be equal to (A) the then-current market price per unit of such Exclusive JV Products (or, if not available, an appropriate proxy as mutually agreed by the Parties) less (B) the per-unit cost of production associated with such Exclusive JV Products and less (C) per unit selling expenses that the Proposing Party would have incurred had such Exclusive JV Products been sold to a Third Party and less (D) any other deductions that would be typically taken under a Net Income calculation (as described in the example set forth in Exhibit D of the Agreement) if there were a sale to a Third Party.

G. In the event that the Receiving Party declines or otherwise does not exercise the Exclusive Products Sole Risk Production Right of First Refusal within the relevant time period as described above (whether in the first instance or pursuant to clause (E) above), then the Receiving Party may at any time (until expiration of the right as described below) elect to exercise an opportunity to opt in to the Proposed Project on the terms last offered (an “Exclusive Sole-Risk Opt-In Right”). The Exclusive Sole-Risk Opt-In Right, if exercised, would be effected by transitioning the Proposed Project to the Holding JV Company (or such other JV Company agreed by the Parties) as promptly as practical and in connection therewith the Proposing Party receiving an amount equal to costs previously incurred for the Independent Project (“Repayment Base Amount”) (where the payment therefore shall be made by the Holding JV Company or as otherwise agreed by the Parties) as follows:


•	The Repayment Base Amount plus interest in USD thereon at libor 1y + 10% of the Repayment Base Amount, if the Exclusive Sole-Risk Opt-In Right is exercised prior to the first anniversary of the notice of the Proposed Project to the Receiving Party.


•	The Repayment Base Amount plus interest in USD thereon at libor 1y + 15% of the Repayment Base Amount, if the Exclusive Sole-Risk Opt-In Right is exercised after the first anniversary of the notice of the Proposed Project to the Receiving Party but prior to the second anniversary thereof.


•	The Repayment Base Amount plus interest in USD thereon at libor 1y + 20% of the Repayment Base Amount, if the Exclusive Sole-Risk Opt-In Right is exercised after the second anniversary of the notice of the Proposed Project to the Receiving Party but prior to the third anniversary thereof.

Each Exclusive Sole-Risk Opt-In Right shall lapse as of the third anniversary of the notice of the Proposed Project to the Receiving Party. If a Receiving Party timely exercises its Sole Risk Opt-In Right, and commits to fund its portion of the Repayment Base Amount for a particular Proposed Project such Proposed Project shall be developed exclusively through the Holding JV.

H. The Exclusive Sole Risk Production Right of First Refusal mechanism described in this Section 11 (i) will not apply to either Party before the completion of the Renewable Diesel Development Project and (ii) will apply only if TOTAL has chosen not to exercise the TOTAL Royalty Option (as defined in Section 12 below).

I. Any Inventions conceived or reduced to practice in the performance of the Independent Project shall be treated under the Agreement (as amended in this First Amendment) as Collaboration IP.


12.	TOTAL Option Upon the Renewable Diesel Project Completion Date

As used herein, “Renewable Diesel Project Completion Date” shall be December 31st, 2013 or any other date as determined by the Management Committee to achieve the End-Project Milestone (as defined in the Renewable Diesel Development Project Plan).

A. For a period of 90 days following the Renewable Diesel Project Completion Date, TOTAL shall have the option, exercisable in its sole discretion, to notify AMYRIS in writing that TOTAL does not wish to pursue the production or commercialization of the Renewable Diesel Product (such option, the “TOTAL Royalty Option”). Provided TOTAL timely notifies AMYRIS of its decision to exercise the TOTAL Royalty Option (such date of notification, the “Royalty Notification Date”), then the following provisions shall apply:

B. Effective as of the Royalty Notification Date, all of TOTAL's rights in or to any and all Collaboration IP developed during the performance of the Renewable Diesel Development Project Plan (hereinafter, the “Diesel Collaboration IP”) shall terminate and TOTAL shall assign to AMYRIS all right, title and interest of TOTAL in and to Diesel Collaboration IP. TOTAL shall, at AMYRIS' reasonable expense, execute all documents and take all actions reasonably requested by XXXXXX from time to time to perfect XXXXXX' title to and ownership thereof. Prior to the Royalty Notification Date, TOTAL shall not assign or transfer to any of its Affiliates or third parties any such right, title and interest so as to ensure that AMYRIS obtains the benefit of this provision.

C. In consideration of the benefits AMYRIS may derive from the technology and intellectual property developed during the Renewable Diesel Development Project and TOTAL's assignment of its right, title and interest in and to the Diesel Collaboration IP, commencing on the Royalty Notification Date and ending on the date when XXXXXX has paid TOTAL an aggregate amount equal to $150,000,000 (the “Aggregate Royalty Amount”), XXXXXX shall pay TOTAL a royalty of twenty percent (20%) of Net Income (as defined in the Collaboration Agreement) on a yearly basis derived from (i) any licenses under or sales of the Diesel Collaboration IP by AMYRIS or any of its Affiliates to third parties, but not to the extent such licenses or sale relate to the use of the Diesel Collaboration IP for the Initial Non-Exclusive JV Products, and (ii) the Net Income (as defined in the Agreement) of AMYRIS on a consolidated basis other than that derived from a Product resulting from the Biojet Development Program and the Non-Exclusive JV Products (the “TOTAL Diesel IP Royalty”). In addition, in the event AMYRIS sells all or

substantially all of its renewable diesel business prior to the time the time the Aggregate Royalty Amount has been paid, AMYRIS shall pay TOTAL fifty percent (50%) of the net proceeds from such sale up to the then-remaining unpaid amount of the Aggregate Royalty Amount.

For clarity, Net Income shall be calculated in accordance with generally accepted accounting principles consistently applied by AMYRIS and in the event that the foregoing Net Income is negative for a given fiscal quarter, AMYRIS shall not be required to pay any royalty for such fiscal quarter).

D. AMYRIS shall provide TOTAL, upon reasonable advance notice, all information, and access to all advisors and representatives of AMYRIS, as reasonably requested by TOTAL in order for a third party auditor appointed by TOTAL and reasonably acceptable to AMYRIS, and subject to mutually agreeable customary confidentiality restrictions, to verify all calculations and amounts paid pursuant to this Section 12 and to report any inaccuracies to TOTAL.

E. Notwithstanding anything in this Section 12, any JV Company established with regard to JV Products other than Renewable Diesel Products will continue to operate following any exercise of the TOTAL Royalty Option.

F. The TOTAL IP Royalty payments shall cease from the date when the sum of all such TOTAL Royalty payments equals $150,000,000.

G. Notwithstanding anything in this Section 12, beginning on the sixth year from the Royalty Notification Date, the aforementioned royalty in section C (ii) shall be additionally derived from the Non-Exclusive JV Products.


13.	Freedom to Operate.

A. Freedom to Operate Analyses. AMYRIS and TOTAL undertake to perform a freedom to operate (“FTO”) analysis in relevant jurisdictions with respect to intellectual property owned or controlled by Third Parties (“Third Party IP”) relevant to the proposed development, production and commercialization of the Farnesene Renewable Diesel Products (“Renewable Diesel Analysis”) prior to the execution of the Definitive JV Agreements and no later than January 31, 2012, with the objective to determine whether, and to what extent, third party intellectual property rights may limit or preclude (i) the use of the AMYRIS intellectual property to Make and Sell Renewable Diesel Product or (ii) the performance of the Renewable Diesel Project Plan. In addition, prior to starting the development, production or commercialization of any other JV Product in the JV, the Parties shall conduct a similar freedom to operate analysis with regard to Third Party IP relevant to the development, production or commercialization of any JV Products of mutual interest to the Parties from such project on a mutually acceptable timetable. Except as otherwise agreed, the costs of the Renewable Diesel Analysis shall be included in R&D Costs for the Biofene Support Subproject and the costs of any other FTO shall be as mutually agreed.

B. Common Interest Agreement. Prior to commencing the Renewable Diesel Analysis described above, the Parties shall enter into a common interest agreement (the “Common Interest Agreement”) covering the exchange of information among the Parties and their counsel for the purposes of conducting such an FTO analysis in accordance with Paragraph A.

C. Result of FTO Analysis.

(i)

Within 20 business days of the completion of the Renewable Diesel Analysis in accordance with the agreed search and evaluation plan detailing specific deliverables and assessments of identified patent applications and patents owned by Third Parties, each Party shall notify the other if it considers that there is a Significant Risk. For the purpose of this section, “Significant Risk” means any risk that Third Party IP may preclude and/or Significantly Delay the development of Renewable Diesel Products in accordance with the Renewable Diesel Development Project Plan or the commercialization of Renewable Diesel Products. If not such notification is provided, then the consequences described in clause (iii)(a) below shall apply.

For the purpose of this Section 13, “Significantly Delay” means an expected delay of 3 months or more.


(ii)	Upon receipt of such a notice, the Parties shall discuss their concerns about the Significant Risk, including whether to suspend or terminate any or all of the R&D Activities for the Renewable Diesel Project. If the Parties disagree after discussing for a period of 15 business days upon receipt of such notice, then each Party shall have the right, at its election to:

(A)

terminate the Renewable Diesel Development Project, if it believes in good faith that the Significant Risk will have a material adverse impact on the Renewable Diesel Project (i.e., if the Third Party IP appears necessary (i.e., design around would Significantly Delay or significantly increase the cost) for the development, production and/or commercialization of Renewable Diesel Products). Any notice of an intent to terminate on such basis must be provided no later than 10 days prior to the Holding JV Formation Deadline as agreed by the Parties; or

(B)

suspend some or all of the R&D Activities (including the corresponding funding) because it believes in good faith that a Significant Risk may (i) prevent the use of the applicable IP for, or (ii) Significantly Delay the development, production and/or the commercialization of Renewable Diesel Products; any notice of suspension must be provided no later than 15 days before the Holding JV Formation Deadline as agreed by the Parties. The suspension period shall last until there is a decision by the Management Committee of any appropriate corrective actions.


(iii)	At the completion of the process described above, the following shall apply: (a) if there is not a termination of the R&D Activities for the Renewable Diesel Project, TOTAL may not decline to enter into the Definitive JV Agreements on the basis of the results of the Renewable Diesel Product Analysis or (b) if there is a termination of the R&D Activities for the

Renewable Diesel Project, neither Party shall be obligated to enter into any JV Company, except, at TOTAL's request, the Parties shall enter into a JV Company to Make and Sell N.1 and/or N.3 JV Products.


(iv)	Any Dispute regarding whether there is basis for termination as set forth in (A) or suspension as set forth in (B) shall be resolved in accordance with Section 12.2 of the Agreement.

D. Representation and Warranty.

AMYRIS represents and warrants as of the First Amendment Date that to its knowledge there are no pending or issued patent rights of any Third Party that foreclose practice of any AMYRIS Technology for the following purposes: (i) to make farnesene using the Mevalonate Pathway, or (ii) to make or commercialize Farnesene Renewable Diesel Products.

14.

Exception to AMYRIS Representations, Warranties and Covenants in Section 8.2(q). The Parties hereby agree that by exception to Section 8.2(q) of the Agreement, Farnesene Strains may be disclosed to any Third Party during the Term by XXXXXX, provided that such disclosure is (a) under conditions of confidentiality and restrictive use to protect their proprietary nature and commercial value and (b) solely in furtherance of AMYRIS' business for products other than Exclusive JV Products.


15.	Construction. The principles set forth in Section 13.12 of the Agreement shall apply to this First Amendment. References to Sections are references to sections of the Agreement except as otherwise expressly provided.

16.

Amendment Effective Date; Incorporation of Terms; Continuing Effect. This First Amendment shall be deemed effective for all purposes as of the Amendment Effective Date. The amendment to the Agreement set forth in this First Amendment shall be deemed to be incorporated in, and made a part of, the Agreement, and the Agreement and this First Amendment shall be read, taken and construed as one and the same agreement. Except as otherwise expressly amended by this First Amendment, the Agreement shall remain in full force and effect in accordance with its terms and conditions.

17.

Entire Agreement. This First Amendment contains the entire agreement between TOTAL and AMYRIS with respect to the subject matter hereof and supersedes any and all prior agreements and understandings, oral and written, with respect to such matters, including the Term Sheet, effective as of July 26, 2011, between AMYRIS and TOTAL Gas & Power USA SAS.
