On behalf of the Board of Directors, I want to thank you for your continued support of Amyris. We look forward to seeing you at the meeting.

The 2014 Annual Meeting of Stockholders of Amyris, Inc. will be held on Monday, May 12, 2014 at 3:00 p.m. Pacific Time at our headquarters located at 5885 Hollis Street, Suite 100, Emeryville, California for the following purposes:

These items of business are more fully described in the Proxy Statement accompanying this Notice of Annual Meeting of Stockholders. The board of directors has fixed the record date for the annual meeting as April 9, 2014. Only stockholders of record at the close of business on the record date may vote at the meeting or at any adjournment thereof. A list of stockholders eligible to vote at the meeting will be available for review for any purpose relating to the meeting during our regular business hours at our headquarters at 5885 Hollis Street, Suite 100, Emeryville, California 94608 for the ten days prior to the meeting.

These proxy materials are provided in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Amyris, Inc., a Delaware corporation (referred to as “Amyris”, the “Company”, “we”, “us”, or “our”), for our 2014 Annual Meeting of Stockholders to be held at 3:00 p.m. Pacific Time on Monday, May 12, 2014, at our principal executive offices, and for any adjournments or postponements of the annual meeting. These proxy materials were first sent on or about April 14, 2014 to stockholders entitled to vote at the annual meeting.

Our principal executive offices are located at 5885 Hollis Street, Suite 100, Emeryville, California 94608, and our telephone number is (510) 450-0761. This Proxy Statement contains important information for you to consider when deciding how to vote on the matters brought before the meeting. Please read it carefully.

We will bear the expense of soliciting proxies. In addition to these proxy materials, our directors and employees (who will receive no compensation in addition to their regular salaries) may solicit proxies in person, by telephone or email. We will reimburse brokers, banks and other custodians, nominees and fiduciaries (or Intermediaries) for reasonable charges and expenses incurred in forwarding soliciting materials to their clients.

The Board set April 9, 2014, as the record date for the meeting. If you owned shares of our common stock as of the close of business on April 9, 2014, you may attend and vote your shares at the meeting. Each stockholder is entitled to one vote for each share of common stock held on all matters to be voted on. As of April 9, 2014, there were 77,646,658 shares of our common stock outstanding and entitled to vote.

The holders of a majority of our outstanding shares of common stock as of the record date must be present in person or represented by proxy at the meeting in order for there to be a quorum, which is required to hold the meeting and conduct business. If there is no quorum, the holders of a majority of the shares present at the meeting may adjourn the meeting to another date.

You will be counted as present at the meeting if you are present and entitled to vote in person at the meeting or you have properly submitted a proxy card or voter instruction form, or voted by telephone or over the Internet. Both abstentions and broker non-votes (as described below) are counted for the purpose of determining the presence of a quorum.

As of the record date of April 9, 2014, there were 77,646,658 shares of our common stock outstanding and entitled to vote, which means that holders of 38,823,330 shares of our common stock must be present in person or by proxy for there to be a quorum.

There are five proposals scheduled to be voted on at the meeting:

No appraisal or dissenters’ rights exist for any action proposed to be taken at the meeting. We will also consider any other business that properly comes before the meeting. As of the date of this Proxy Statement, we are not aware of any other matters to be submitted for consideration at the meeting. If any other matters are properly brought before the meeting, the persons named in the enclosed proxy card or voter instruction form will vote the shares they represent using their best judgment.

The Board recommends that you vote:

If your shares of Amyris common stock are registered directly in your name with our transfer agent, Wells Fargo Bank, National Association, you are considered, with respect to those shares, to be the stockholder of record. As the stockholder of record, you have the right to vote in person at the meeting.

If your shares are held in a brokerage account or by another Intermediary, you are considered the beneficial owner of shares held in street name. As the beneficial owner, you are also invited to attend the meeting. However, since a beneficial owner is not the stockholder of record, you may not vote these shares in person at the meeting unless you obtain a “legal proxy” from the Intermediary that is the record holder

of the shares, giving you the right to vote the shares at the meeting. The meeting will be held on Monday, May 12, 2014 at 3:00 p.m. Pacific Time at our headquarters located at 5885 Hollis Street, Suite 100, Emeryville, California. You can find directions to our headquarters on our company website at http:/​/​www.amyris.com/​en/​about-amyris/​contact.

Whether you hold shares directly as a registered stockholder of record or beneficially in street name, you may vote without attending the meeting. You may vote by granting a proxy or, for shares held beneficially in street name, by submitting voting instructions to your broker, bank or other trustee or nominee. In most cases, you will be able to do this by using the Internet, by telephone or by mail.

If you are a stockholder of record and you either indicate when voting on the Internet or by telephone that you wish to vote as recommended by the Board, or you sign and return a proxy card without giving specific voting instructions, then the proxy holders will vote your shares in the manner recommended by the Board on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the meeting.

If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, under stock market rules, the organization that holds your shares may generally vote at its discretion only on routine matters and cannot vote on non-routine matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the organization will inform the inspector of election that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to as a “broker non-vote.” In tabulating the voting results for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on that proposal. Thus, broker non-votes will not affect the outcome of Proposals 1 (which requires a plurality of votes properly cast in person or by proxy) and 2 and 5 (which each require a majority of the votes cast on such proposal), assuming that a quorum is obtained, and will have the effect of a vote against Proposal 3.

The ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2014 (Proposal 4) is considered routine under applicable rules. The election of directors (Proposal 1), the non-binding advisory vote on executive compensation (Proposal 2), the approval of the proposed amendment to our certificate of incorporation (Proposal 3) and the approval of the proposed issuance of senior secured convertible promissory notes (Proposal 5), are considered non-routine under applicable rules. A broker or other nominee cannot vote without instructions on non-routine matters, and therefore we expect there to be broker non-votes on Proposals 1, 2, 3 and 5.

Votes will be counted by the inspector of election appointed for the meeting. The inspector of election will separately count “For” and “Withhold” votes and any broker non-votes in the election of directors. With respect to the other proposals, the inspector of election will separately count “For” and “Against” votes, abstentions and, other than with respect to Proposal 4 which should not have broker non-votes given that it is considered a routine proposal, any broker non-votes. Abstentions will be counted toward the vote

totals for these proposals and will have the same effect as an “Against” vote. Broker non-votes will not count toward the vote totals for Proposals 2 and 5 and will not count for or against such proposals, but will have the same effect as an “Against” vote for Proposal 3.

You may revoke your proxy and change your vote at any time before the final vote at the meeting. If you are a stockholder of record, you may do this by signing and submitting a new proxy card with a later date, by using the Internet or voting by telephone (either of which must be completed by 11:59 p.m. Pacific Time on May 11, 2014 — your latest telephone or Internet proxy is counted), or by attending the meeting and voting in person. Attending the meeting alone will not revoke your proxy unless you specifically request that your proxy be revoked. If you hold shares through a bank or brokerage firm, you must contact that bank or firm directly to revoke any prior voting instructions.

The preliminary voting results will be announced at the meeting. The final voting results will be reported in a current report on Form 8-K, which we expect to file with the Securities and Exchange Commission within four business days after the meeting. If final voting results are not available within four business days after the meeting, we intend to file a current report on Form 8-K reporting the preliminary voting results within that period, and subsequently file the final voting results in an amendment to the current report on Form 8-K within four business days after the final voting results are known to us.

This Proxy Statement contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements may be identified by their use of such words as “expects,” “anticipates,” “intends,” “hopes,” “anticipates,” “believes,” “could,” “may,” “will,” “projects” and “estimates,” and other similar expressions, but these words are not the exclusive means of identifying such statements. We caution that a variety of factors, including but not limited to the following, could cause our results to differ materially from those expressed or implied in our forward-looking statements: our cash position and ability to fund our operations, our limited operating history and lack of revenues generated from the sale of our renewable products; our inability to decrease production costs to enable sales of our products at competitive prices; delays in production and commercialization of products due to technical, operational, cost and counterparty challenges; challenges in developing customer base in markets with established and sophisticated competitors; currency exchange rate and commodity price fluctuations; changes in regulatory schemes governing genetically modified organisms and renewable fuels and chemicals, and other risks detailed from time to time in filings we make with the Securities and Exchange Commission, including our Annual Reports on Form 10-K, our Quarterly Reports on Form 10-Q and our Periodic Reports on Form 8-K. Except as required by law, we assume no obligation to update any forward-looking information that is included in this Proxy Statement.

Under our certificate of incorporation and bylaws, the number of authorized Amyris directors has been fixed at 10 and the Board is divided into three classes with staggered three-year terms:

In accordance with the certificate of incorporation, the Board has assigned each member of the Board to one of the three classes, with the number of directors in each class divided as equally as reasonably possible. As of the date of this Proxy Statement, there are four Class I seats, three Class II seats, and three Class III seats constituting the 10 seats on the Board.

Stockholders are being asked to vote for the four Class I nominees listed below to serve until our 2017 Annual Meeting of Stockholders and until each such director’s successor has been elected and qualified, or each such director’s earlier death, resignation or removal. The nominees are all current directors of Amyris. Dr. Duyk was appointed by the unanimous written consent of the Board in May 2012. Dr. Duyk previously served on the Board from May 2006 to May 2011. Two of the four (Mr. Reinach and Ms. Piwnica) were appointed by the unanimous written consent of the Board in connection with our 2010 reincorporation in Delaware and in preparation for our initial public offering, and served on the board of directors of our California corporation predecessor. Ms. Piwnica was also later named to serve on the Board as a designee by Naxyris SA, an investment vehicle owned by Naxos Capital Partners SCA Sicar (“Naxos”) in 2012 under an agreement between Amyris and Naxos. HH Sheikh Abdullah bin Khalifa Al Thani (“HH”) was appointed by the unanimous written consent of the Board in 2012 and was designated by Biolding Investment SA (“Biolding”), a company HH controls, to serve on the Board under an agreement between Amyris and Biolding.

Directors are elected by a plurality of the votes properly cast in person or by proxy. This means that the four Class I nominees receiving the highest number of affirmative (i.e., “For”) votes will be elected. At the annual meeting, proxies cannot be voted for a greater number of persons than the four nominees named in this Proposal 1 and stockholders cannot cumulate votes in the election of directors. Shares represented by executed proxies will be voted by the proxy holders, if authority to do so is not withheld for any or all of the nominees, “For” the election of the four nominees named below. If any nominee is unable or declines to serve as a director at the time of the meeting, the proxies will be voted for a nominee, if any, designated by the Board to fill the vacancy. As of the date of this Proxy Statement, the Board is not aware that any nominee up for election is unable or will decline to serve as a director. If you hold shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote so that your vote can be counted on this proposal.

The following tables and biographies set forth information as of March 15, 2014 for each nominee for election at the annual meeting and for each director of Amyris whose term of office will continue after the annual meeting:

.ComDominio S/A, a datacenter company. Dr. Reinach holds a Bachelor of Science degree in biology from the University of São Paulo and a Doctor of Philosophy degree in Cell and Molecular Biology from Cornell University Medical College.

1990; senior vice president, Research in 1992; and senior vice president, Research and Development in 1993. In September 2013, Dr. Levinson was named Chief Executive Officer of Calico, a company focused on health, aging and well-being. Dr. Levinson holds several Board of Directors positions in addition to Amyris, Roche and Genentech. Dr. Levinson was appointed Chairman of the Board of Apple in November 2011. He served as a co-lead director of Apple’s Board of Directors since 2005 and a director since 2000. He is a director of NGM Biopharmaceuticals, Inc. and the Broad Institute of MIT and Harvard.

Dr. Levinson received the Irvington Institute’s 1999 Corporate Leadership Award in Science and was honored the same year with the Corporate Leadership Award from the National Breast Cancer Coalition. He was inducted into the Biotech Hall of Fame at the 2003 Biotech Meeting of chief executive officers. BusinessWeek named Levinson one of the “Best Managers of the Year” in 2004 – 2005, and Institutional Investor named him “America’s Best CEO” in the biotech category four years in a row (2004 – 2007). In 2006, Princeton University awarded Dr. Levinson the James Madison Medal for a distinguished career in scientific research and in biotechnology. Also in 2006, Barron’s recognized Dr. Levinson as one of “The World’s Most Respected CEOs,” and the Best Practice Institute placed Levinson on their “25 Top CEOs” list. In 2008, Dr. Levinson was elected as a Fellow to the American Academy of Arts & Sciences.

Dr. Levinson received his Bachelor of Science degree from the University of Washington and earned a doctorate in Biochemical Sciences from Princeton University. Dr. Levinson’s experience with the biotechnology industry has enabled him to provide insight and guidance to our management team and the Board.

There are no arrangements between any of the nominees and any other party pursuant to which such nominee has been selected as a nominee for election at the annual meeting other than our arrangements with Biolding regarding the nomination of HH described below and our arrangements with Naxos regarding the nomination of Ms. Piwnica.

HH was designated to serve on the Board by Biolding, an affiliate of HH, under a letter agreement (the “Letter Agreement”) we entered into in February 2012 in connection with a private placement of our common stock. In connection with such financing, we agreed to appoint one person designated by Biolding to serve as a member of the Board, and to use reasonable efforts consistent with the Board’s fiduciary duties, to cause the director designated by Biolding to be re-nominated by the Board in the future. These designation rights terminate upon a sale of Amyris or upon Biolding holding less than 2,595,155 shares of our common stock.

Under the Letter Agreement, we also agreed to appoint one person designated by each of Naxyris SA, an investment vehicle owned by Naxos Capital Partners SCA Sicar, and Maxwell (Mauritius) Pte Ltd (“Maxwell”), which were additional purchasers in the February 2012 common stock offering. Naxyris SA purchased 1,730,103 shares of our common stock and Maxwell purchased 2,595,155 shares our common stock in the offering. Naxyris SA designated Ms. Piwnica (who was already on the Board) to serve as the Naxyris SA representative on the Board, and Maxwell designated Dr. Chua to serves as the Maxwell representative on the Board. These designation rights terminate upon a sale of Amyris or, as applicable, Naxyris SA holding less than 1,730,103 shares of our common stock and Maxwell holding less than 2,595,155 shares of our common stock.

Mr. Doerr was appointed to the Board by Kleiner Perkins Caufield & Byers pursuant to a voting agreement as most recently amended and restated on June 21, 2010. As of the date of this Proxy Statement, notwithstanding the expiration of the voting agreement upon completion of our initial public offering in September 2010, Mr. Doerr continues to serve on the Board and we expect him to continue to serve as a director until his resignation or until his successor is duly elected by the holders of our common stock.

Mr. Boisseau was designated to serve on the Board by Total under a letter agreement between Amyris and Total. As of March 15, 2014, Total beneficially owned 13,617,212 shares of our common stock, representing approximately 17.7% of our outstanding common stock. In June 2010, we issued Series D preferred stock to Total that converted into shares of our common stock upon the completion of our initial public offering in September 2010. In connection with such equity investment, we agreed to appoint a person designated by Total to serve as a member of the Board, and to use reasonable efforts, consistent with the Board’s fiduciary duties, to cause the director designated by Total to be re-nominated by the Board in the future. These membership rights terminate upon the earlier of Total holding less than half of the shares of common stock issued upon conversion of the Series D preferred stock or a sale of Amyris.

Under the corporate governance rules of The NASDAQ Stock Market (“NASDAQ”), a majority of the members of our Board must qualify as “independent,” as affirmatively determined by our Board. Our Board and the Nominating and Governance Committee of the Board consult with our legal counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in the applicable NASDAQ rules. The NASDAQ criteria include various objective standards and a subjective test. A member of the Board is not considered independent under the objective standards if, for example, he or she is, or at any time during the past three years was, employed by Amyris, or he or she is an executive officer of any organization to which Amyris made, or from which the Amyris received, payments for property or services in the current or any of the past three fiscal years that exceed 5% of the recipient’s gross revenues for that year, or $200,000, whichever is more (other than payments arising solely from investments in our securities or payments under non-discretionary charitable contribution matching programs). Mr. Melo is not deemed independent because he is an Amyris employee. The Board did not find Mr. Boisseau to be independent because he is an officer of Total S.A., an affiliate of Total (with which we have a joint venture arrangement that may involve annual payments exceeding 5% of our yearly gross revenues and $200,000, as described in more detail later in this Proxy Statement under the caption “Transactions with Related Persons”).

The subjective test under the NASDAQ criteria for director independence requires that each independent director not have a relationship which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. The subjective evaluation of director independence by the Board was made in the context of the objective standards referenced above. In making independence determinations, the Board generally considers commercial, financial and professional services, and other transactions and relationships between Amyris and each director and his or her family members and affiliated entities. For each of the directors other than Messrs. Boisseau and Melo, the Board determined that none of the transactions or other relationships exceeded NASDAQ objective standards and none would otherwise interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making this determination, the Board considered certain relationships that did not exceed NASDAQ objective standards and determined that none of these relationships would interfere with the exercise of independent judgment by the director in carrying out his or her responsibilities as a director. The following is a description of these relationships:

Maxwell, Naxyris SA, TPG Biotechnology Partners II, L.P., entities affiliated with KPCB Holdings, Inc. and Lit Tele LLC, purchased shares of our predecessor’s preferred stock in a series of preferred stock financings completed during the period from May 2006 through January 2010, and such preferred stock converted to common stock on completion of our initial public offering.

Consistent with these considerations, after review of all relevant transactions and relationships between each director, any of his or her family members, Amyris, our executive officers and our independent registered public accounting firm, the Board affirmatively determined that a majority of our Board is comprised of independent directors, and that the following directors are independent: Nam-Hai Chua, John Doerr, Geoffrey Duyk, Arthur Levinson, Carole Piwnica, Fernando de Castro Reinach, HH and R. Neil Williams.

Our Board is composed of our Chief Executive Officer, John Melo, and nine non-management directors. Arthur Levinson, one of our independent directors, currently serves the principal Board leadership role as the Board’s Chairman. Our Board expects to appoint an independent director as Chairman following Dr. Levinson’s resignation from the Board effective as of the 2014 Annual Meeting. The Board does not have any policy that the Chair must necessarily be separate from the chief executive officer, but the Board appointed Dr. Levinson as Chairman in May 2012; Dr. Levinson served as Lead Independent Director from March 2011 to May 2012. Dr. Levinson’s (and his successor’s) responsibilities as Chairman include providing input on Board agendas and working with management to develop agendas for meetings, calling special meetings of the Board, presiding at executive sessions of independent Board members, gathering input from Board members on chief executive officer performance and providing feedback to the chief executive officer, and gathering input from Board members after meetings and through an annual self-assessment process and communicating feedback to the Board and the Chief Executive Officer, as appropriate. The Board believes that having an independent Chair helps reinforce the Board’s independence from management in its oversight of our business and affairs. In addition, the Board believes that this structure helps to create an environment that is conducive to objective evaluation and oversight of management’s performance and related compensation, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in our best interests and those of our stockholders. Further, this structure permits our Chief Executive Officer to focus on the management of our day-to-day operations. Accordingly, we believe our current Board leadership structure contributes to the effectiveness of the Board as a whole and, as a result, is the most appropriate structure for us at the present time.

We consider risk as part of our regular consideration of business strategy and business decisions. Assessing and managing risk is the responsibility of our management, which establishes and maintains risk management processes, including prioritization, action plans and mitigation measures, designed to balance

the risk and benefit of opportunities and strategies. It is management’s responsibility to anticipate, identify and communicate risks to the Board and/or its committees. The Board as a whole oversees our risk management systems and processes, as implemented by management and the Board’s committees. As part of its oversight role, the Board has adopted an enterprise risk management process that involves management discussions with and updates to members of the Audit Committee regarding enterprise risk prioritization and mitigation. In addition, the Board uses its committees to assist in its risk oversight function as follows:

The Board receives regular reports from committee Chairs regarding the committees’ activities. In addition, discussions with the Board about our strategic plan and objectives, business results, financial condition, compensation programs, strategic transactions, and other business discussed with the Board, include a discussion of the risks associated with the particular item under consideration.

During fiscal year 2013, our Board had seven meetings, and its three standing committees (the Audit Committee, Leadership Development and Compensation Committee, and Nominating and Governance Committee) collectively had 22 meetings. With the exception of HH, who attended four of seven meetings of the Board during fiscal year 2013, each incumbent director attended at least 75% of the meetings (held during the period that such director served) of the Board and the committees on which such director served in fiscal year 2013. The Board’s policy is that directors are encouraged to attend our annual meetings of stockholders. Two directors attended our 2013 annual meeting of stockholders.

The following table provides membership and meeting information for the Board and its committees in fiscal year 2013:

Our Board has established an Audit Committee, a Leadership Development and Compensation Committee, and a Nominating and Governance Committee, each as described below. Members serve on these committees until their resignations or until otherwise determined by the Board.

The Audit Committee was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and assists the Board in fulfilling the Board’s oversight of our accounting and system of internal controls, the quality and integrity of our financial reports, and the retention, independence and performance of our independent registered public accounting firm.

Under NASDAQ rules, we must have an audit committee of at least three members, each of whom must be independent as defined under the rules and regulations of NASDAQ the Securities and Exchange Commission (the “SEC”) rules and regulations. Our Audit Committee is currently composed of three directors: Messrs. Reinach, Williams and Dr. Duyk. Mr. Williams is the Chair of the Audit Committee. The composition of the Audit Committee meets the requirements for independence under current NASDAQ and SEC rules and regulations. The Board has determined that each member of the Audit Committee is independent (as defined in the relevant NASDAQ and SEC rules and regulations), and is financially literate and able to read and understand fundamental financial statements, including a company’s balance sheet, income statement and cash flow statement. In addition, the Board has determined that Mr. Williams is an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the “Securities Act”) with employment experience in finance and accounting and other comparable experience that results in his financial sophistication. Being an “audit committee financial expert” does not impose on Mr. Williams any duties, obligations or liabilities that are greater than are generally imposed on him as a member of the Audit Committee and the Board. The Board has adopted a written charter for our Audit Committee that is posted on our company website at http:/​/​investors.amyris.com/​governance.cfm.

The Audit Committee performs the following functions:

In addition, the Audit Committee generally reviews and approves any proposed transaction between Amyris and any related party, establishes procedures for receipt, retention and treatment of complaints received by Amyris regarding accounting, internal accounting controls or auditing matters, and for the confidential, anonymous submission by employees of Amyris, of their concerns regarding questionable accounting or auditing matters (including administration of our whistleblower policy established by the Nominating and Governance Committee), and oversees the review of any complaints and submissions received through the complaint and anonymous reporting procedures.

Under NASDAQ rules, compensation of the executive officers of a company must be determined, or recommended to the Board for determination, either by independent directors constituting a majority of the Board’s independent directors in a vote in which only independent directors participate, or by a compensation committee composed solely of independent directors. Amyris has established the Leadership Development and Compensation Committee for such matters, which is currently composed of three directors: Mr. Doerr, Ms. Piwnica and Dr. Chua. Ms. Piwnica is the Chair of the Leadership Development and Compensation Committee. The Board has determined that each member of the Leadership Development and Compensation Committee is independent (as defined in the relevant NASDAQ and SEC rules and regulations). The Board has adopted a written charter for our Leadership Development and Compensation Committee that is posted on our company website at http:/​/​investors.amyris.com/​governance.cfm.

The purpose of the Leadership Development and Compensation Committee is to provide guidance and periodic monitoring for all of our compensation, benefit, perquisite and employee equity programs. The Leadership Development and Compensation Committee, through delegation from the Board, has principal responsibility to evaluate, recommend, approve and review executive officer and director compensation arrangements, plans, policies and programs maintained by Amyris and to administer our cash-based and equity-based compensation plans, and may also make recommendations to the Board regarding the Board’s remaining responsibilities relating to executive compensation. The Leadership Development and Compensation Committee discharges the responsibilities of the Board relating to compensation of our executive officers, and, among other things:

The Leadership Development and Compensation Committee also reviews the Compensation Discussion and Analysis section of our Annual Report on Form 10-K and Proxy Statement and recommends to the Board whether it be included in the Proxy Statement, and prepares a report of the

committee for inclusion in the Annual Report on Form 10-K and Proxy Statement for our annual meetings in accordance with SEC rules. The Leadership Development and Compensation Committee has authority to form and delegate authority to subcommittees, as appropriate.

The Board has established a Management Committee for Employee Equity Awards, consisting of our Chief Human Resources Officer and our Chief Executive Officer. This committee may grant stock awards to employees who are not officers (as that term is defined in Section 16 of the Exchange Act and Rule 16a-1 promulgated under the Exchange Act) of Amyris, provided that this committee is authorized to grant only stock awards that meet stock award grant guidelines approved by the Board or Leadership Development and Compensation Committee. These guidelines set forth, among other things, any limit imposed by the Board or Leadership Development and Compensation Committee on the total number of shares that may be subject to equity awards granted to employees by the Management Committee for Employee Equity Awards, and any requirements as to the size of an award based on the seniority of an employee or other factors.

Under its charter, the Leadership Development and Compensation Committee, has the authority, at the expense of Amyris, to retain legal and other consultants, accountants, experts and advisors of its choice to assist the committee in connection with its functions. During the past fiscal year, the Leadership Development and Compensation Committee engaged Compensia, Inc. as its compensation consultant. (Compensia also served as the committee’s compensation consultant for 2012.) Compensia provided the following services during fiscal year 2013 (or in connection with 2013 compensation):

Compensia (including its affiliates) did not perform any services for us or any of our affiliates other than compensation consulting services related to determining or recommending the form or amount of executive and director compensation, designing and implementing incentive plans, and providing information on industry and peer group pay practices, which services were provided directly to the Leadership Development and Compensation Committee. The committee approved all such services performed by Compensia during 2013 and determined in connection with such approvals that Compensia did not have any relationships with Amyris or any of its officers or directors (other than the approved compensation consulting services) or any conflicts of interest that would impair its independence.

The Human Resources, Finance and Legal departments of Amyris work with our Chief Executive Officer to design and develop new compensation programs applicable to executive officers and directors, to recommend changes to existing compensation programs, to recommend financial and other performance targets to be achieved under those programs, to prepare analyses of financial data, to prepare peer compensation comparisons and other committee briefing materials, and to implement the decisions of the Leadership Development and Compensation Committee. Members of these departments and our Chief Executive Officer also meet separately with Compensia to convey information on proposals that management may make to the Leadership Development and Compensation Committee, as well as to allow

Compensia to collect information about Amyris to develop its recommendations. In addition, our Chief Executive Officer conducts reviews of the performance and compensation of the other executive officers, and based on these reviews and input from Compensia, and our Human Resources department, makes recommendations regarding executive compensation (other than his own) directly to the Leadership Development and Compensation Committee. None of our executive officers participated in the determinations or deliberations of the Leadership Development and Compensation Committee regarding the amount of any component of his or her own fiscal year 2013 compensation.

Under NASDAQ rules, director nominees must be selected, or recommended for the Board’s selection, either by independent directors constituting a majority of the Board’s independent directors, or by a nominations committee composed solely of independent directors. Amyris has established the Nominating and Governance Committee for such matters, which is currently composed of two directors: Mr. Doerr and Ms. Piwnica. Mr. Doerr is the Chair of the Nominating and Governance Committee. The Board has determined that each member of the Nominating and Governance Committee is independent (as defined in the relevant NASDAQ and SEC rules and regulations). The Board has adopted a written charter for our Nominating and Governance Committee that is posted on our company website at http:/​/​investors.amyris.com/​governance.cfm.

The purpose of the Nominating and Governance Committee is to ensure that the Board is properly constituted to meet its fiduciary obligations to stockholders and Amyris, and to assist the Board with respect to corporate governance matters, including:

The Nominating and Governance Committee also monitors the size, leadership and committee structure of the Board and makes any recommendations for changes to the Board, reviews our narrative disclosures in SEC filings regarding the director nomination process, Board leadership structure and risk oversight by the Board, considers and approves any requested waivers under our Code of Business Conduct and Ethics, reviews and makes recommendations to the Board regarding formal procedures for stockholder communications with members of the Board, reviews with the Chief Executive Officer and Board leadership the succession plans for senior management positions, and oversees an annual self-evaluation process for the Board.

In carrying out its duties to consider and nominate candidates for membership on the Board, the Nominating and Governance Committee considers a mix of perspectives, qualities and skills that would contribute to the overall corporate goals and objectives of Amyris and to the effectiveness of the Board. The committee’s goal is to nominate directors who will provide a balance of industry, business and technical knowledge, experience and capability. To this end, the committee considers a variety of characteristics for director candidates, including demonstrated ability to exercise sound business judgment, relevant industry or business experience, understanding of and experience with issues and requirements facing public companies, excellence and a record of professional achievement in the candidate’s field, relevant technical knowledge or aptitude, having sufficient time and energy to devote to the affairs of Amyris, independence for purposes of compliance with NASDAQ and SEC rules and regulations as applicable, and commitment to rigorously represent the long-term interests of our stockholders. Although the committee uses these and other criteria to evaluate potential nominees, we have no stated minimum criteria for nominees. While we do not have a formal policy with regard to the consideration of diversity in identifying director nominees, the committee strives to nominate directors with a variety of complementary skills and experience so that, as a group, the Board will possess the appropriate talent, skills and experience to oversee our business.

The Nominating and Governance Committee generally uses the following processes for identifying and evaluating nominees for director:

The Nominating and Governance Committee will consider director candidates recommended by stockholders and will use the same criteria to evaluate all candidates. We have not received a recommendation for a director nominee for the 2015 annual meeting from a stockholder or stockholders. Stockholders who wish to recommend individuals for consideration by the Nominating and Governance Committee to become nominees for election to the board may do so by delivering a written recommendation to the Nominating and Governance Committee at the following address: Chair of the Nominating and Corporate Governance Committee c/o Secretary of Amyris, Inc. at 5885 Hollis Street, Suite 100, Emeryville, California 94608, at least 120 days prior to the anniversary date of the mailing of our Proxy Statement for the last annual meeting of stockholders, which for our 2015 annual meeting of stockholders is a deadline of December 10, 2014. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience and directorships for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record owner of our Common Stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Stockholders who wish to nominate persons directly for election to the Board at an annual meeting of stockholders must meet the deadlines and other requirements set forth in our bylaws and the rules and regulations of the SEC. As provided in our certificate of incorporation, subject to the rights of the holders of any series of preferred stock, any vacancy occurring in the Board can generally be filled only by the affirmative vote of a majority of the directors then in office. The director appointed to fill the vacancy will hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which the director has been assigned expires or until such director’s successor shall have been duly elected and qualified.

The Board has established a process by which stockholders may communicate with the Board or any of its members, including the Chairman of the Board, or to the independent directors generally. Stockholders and other interested parties who wish to communicate with the Board or any of the directors may do so by sending written communications addressed to the Secretary of Amyris at 5885 Hollis Street, Suite 100, Emeryville, California 94608. The Board has directed that all communications will be compiled by the Secretary and submitted to the Board or the selected group of directors or individual directors on a periodic basis. These communications will be reviewed by our Secretary, who will determine whether they should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements and solicitations). The screening procedures have been approved by a majority of the non-management directors of the Board. Directors may at any time request that we forward to them immediately all communications received by us. All communications directed to the Audit Committee in accordance with the procedures described above that relate to accounting, internal accounting controls or auditing matters involving Amyris will be promptly and directly forwarded to all members of the Audit Committee.

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, the stockholders of Amyris may cast an advisory and non-binding vote at the Annual Meeting in relation to the compensation of our named executive Officers as disclosed in this Proxy Statement in accordance with SEC rules. Our practice, which was approved by our stockholders at the 2011 Annual Meeting, is to conduct this non-binding vote on a triennial basis. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement.

This proposal is set forth in the following resolution:

As an advisory vote, this proposal is non-binding. Although the vote is non-binding, the Board and the Leadership Development and Compensation Committee value the opinions of our stockholders, and will carefully consider the outcome of the vote when making future compensation decisions for our named executive officers.

As described more fully in the Compensation Discussion & Analysis, the Board and the Leadership Development and Compensation Committee believe that our compensation policies, which set forth clear and simple objectives, will yield the best results.

Our objectives are to:

We believe our compensation program is aligned with the long-term interests of our stockholders and that our compensation policies provide an appropriate blend of compensation to retain our executives, reward them for performance in the short term and induce them to contribute to the creation of value in Amyris over the long term. We view the different components of our executive compensation as distinct, each serving particular functions in furthering our compensation philosophy and objectives, and together providing a holistic approach to achieving such philosophy and objectives.

Our executive competitive compensation program is designed to enable us to attract and retain the top executives and employees necessary to develop our business, while being prudent in the management of our cash and equity. Based on this approach, we continue to aim to balance and reward annual and long-term performance with a total compensation package that includes a mix of both cash and equity. Our compensation program is intended to align the interests of management, key employees and stockholders and to encourage the creation of stockholder value by providing long-term incentives through equity ownership. The Compensation Discussion and Analysis set forth on pages 39 – 51 of this Proxy Statement explain our compensation philosophy in greater detail. We urge you to read the Compensation Discussion and Analysis section for additional details on our executive compensation, including our compensation philosophy and objectives and the 2013 compensation of the named executive officers.

The proposal must receive a “For” vote from the holders of a majority of the votes cast on the proposal at the annual meeting in person or by proxy. Abstentions will be counted toward the vote total for the proposal and will have the same effect as an “Against” vote. Shares represented by executed proxies that do not indicate a vote “For,” “Against” or “Abstain” will be voted by the proxy holders “For” the adoption of the resolution. If you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal. Broker non-votes will not count toward the vote total for this proposal and will not count for or against the proposal.

We are asking stockholders to approve an amendment to our certificate of incorporation to increase the number of total authorized shares from 205,000,000 shares to 305,000,000 shares and the number of authorized shares of common stock from 200,000,000 shares to 300,000,000 shares.

The additional common stock will have rights identical to our currently outstanding common stock. The number of authorized shares of our preferred stock will not be affected by this amendment; it will be maintained at 5,000,000 shares. No shares of preferred stock have been issued, and we currently have no plans, arrangements, commitments or understandings with respect to the issuance of any shares of preferred stock.

The reason for the proposed amendment is to increase our financial flexibility and to facilitate our ability to continue implementing our employee equity programs at competitive levels. Our cash flow from operations has been, and continues to be, negative. We have reported in our recent quarterly and annual reports on Form 10-Q and 10-K that we need to raise additional operating capital. The Board may determine that the optimal manner for doing so is the sale of equity securities, instruments convertible into equity securities and/or options or rights to acquire equity securities. For example, in 2013, we engaged in multiple financings involving the private placement of our common stock or convertible promissory notes.

As of March 15, 2014, approximately 87.3% of our currently authorized common stock has either been issued, or is reserved for issuance under our equity incentive plans and upon conversion of outstanding convertible promissory notes, after taking into consideration the full potential of interest that accrues and can convert to equity. We do not currently have enough shares authorized to provide for sufficient flexibility to pursue appropriate equity financing opportunities if they arise or to take certain other actions that the Board may determine is in the best interests of Amyris and the best interests of our stockholders.

The Board believes it is desirable for us to have the flexibility to issue, without further stockholder action, additional shares of common stock in excess of the amount that is currently authorized. As is the case with the current authorized, unreserved, but unissued shares of common stock, the additional shares of common stock authorized by this proposed amendment could be issued upon approval by the Board without further vote of our stockholders except as may be required in particular cases by applicable law, regulatory agencies or, if the shares of common stock become listed, the rules of a stock exchange. Such shares would be available for issuance from time to time as determined by the Board for any proper corporate purpose. Such purposes might include, without limitation, issuance in public or private sales for cash as a means of obtaining additional capital for use in our business and operations, issuance in repayment of indebtedness and/or issuance pursuant to stock plans relating to options, stock appreciation rights, restricted stock, restricted stock units and other equity grants.

Article IV of our certificate of incorporation, as amended, currently authorizes us to issue up to 205,000,000 shares of stock, with 200,000,000 designated as common stock and 5,000,000 designated as preferred stock. At our 2013 annual meeting of stockholders our stockholders approved the increase of our total authorized shares from 105,000,000 shares to 205,000,000 shares and the number of authorized shares of common stock from 100,000,000 shares to 200,000,000 shares. In March 2014, the Board approved the advisability of and adopted, subject to stockholder approval, an amendment to Article IV to again increase the total authorized shares and the authorized shares of common stock as described above. This amendment to the certificate of incorporation requires approval of both the Board and our stockholders. Accordingly, we are seeking stockholder approval for the amendment by means of this Proxy Statement.

The proposal must receive a “For” vote from the holders of a majority of our outstanding shares of common stock entitled to vote at the annual meeting, irrespective of the number of votes cast on the proposal at the meeting. Abstentions and broker non-votes will have the same effect as an “Against” vote for this proposal. Shares represented by executed proxies that do not indicate a vote “For,” “Against” or

“Abstain” will be voted by the proxy holders “For” the adoption of the resolution. If you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal.

Our common stock consists of a single class, with equal voting, distribution, liquidation and other rights. As of March 15, 2014, of our 200,000,000 shares of authorized common stock, 77,038,444 shares were outstanding and 97,573,629 shares were reserved for issuance under our equity plans, outstanding convertible promissory notes and other outstanding rights to acquire common stock. As of March 15, 2014, we had 19,644,669 shares reserved for issuance under our equity incentive plans, 60,000 shares reserved for non-equity incentive plan related options, 1,021,087 shares reserved for issuance under outstanding warrants, and 76,847,873 shares reserved for issuance under outstanding convertible promissory notes, which includes interest convertible to common stock under certain of such notes. This leaves only 25,387,927 shares of common stock that are authorized but not issued and outstanding or reserved for issuance. We also expect to issue up to an aggregate of $21.7 million in senior convertible promissory notes to Total in July 2014 and January 2015. The arrangements with Total are described in more detail below in this Proxy Statement under the caption “Transactions with Related Persons — Total Transactions,” and the number of shares issuable under such senior convertible promissory notes is subject to increase if Proposal 5 is adopted. Please see “Proposal 5 — Approval of the issuance of up to $21,700,000 aggregate principal amount of senior secured convertible promissory notes in a private placement transaction and the issuance of the common stock issuable upon conversion of such notes, in accordance with NASDAQ Marketplace Rule 5635.”

The increase in authorized shares of common stock will give the Board the flexibility to undertake certain transactions to support our business operations, without the potential expense or delay associated with obtaining stockholder approval for any particular issuance. For example, we could issue additional shares of common stock in the future in connection with one or more of the following (subject to laws, regulations or stock market rules that might require stockholder approval of certain transactions):

If this proposal is adopted, the additional authorized shares of common stock can be issued or reserved with approval of the Board at times, in amounts, and upon terms that the Board may determine, without additional stockholder approval. Stockholder approval of this proposal will not, by itself, cause any change in our capital accounts. However, any future issuance of additional shares of authorized common stock, or securities convertible into common stock, would ultimately result in dilution of existing stockholders’ equity interests and could have a dilutive effect on book value per share and any future

earnings per share. Dilution of equity interests could also cause prevailing market prices for our common stock to decline. Current stockholders (other than those who are party to specific rights agreements with us as described under “Transactions with Related Persons”) will not have preemptive rights to purchase additional shares.

In addition to dilution, the availability of additional shares of common stock for issuance could, under certain circumstances, discourage or make more difficult any efforts to obtain control of Amyris. For example, significant stock and convertible security issuances in connection with a series of private-placement financing efforts since 2012 have resulted in further concentration of ownership of Amyris by related parties during the course of the year, and we expect to undertake additional financing efforts in 2014 and beyond involving issuances of securities to Total and, potentially, other related persons, as described in “Transactions with Related Persons.” Such concentration of ownership could make it more difficult for an unrelated third party to undertake an acquisition of us. The Board is not aware of any actual or contemplated attempt to acquire control of Amyris and this proposal is not being presented with the intent that it be used to prevent or discourage any acquisition attempt. However, nothing would prevent the Board from taking any actions that it deems consistent with its fiduciary duties.

Because our cash flow from operations has been negative, if the stockholders do not approve this proposal, the Board may be precluded from pursuing a wide range of potential corporate opportunities that might raise necessary cash or otherwise be in the best interests of Amyris and the best interests of our stockholders. This could have a material adverse effect on our business and prospects. We would also face substantial challenges in hiring and retaining employees at all levels, including our executive leadership team, in the near term.

Some of our directors are affiliated with entities that may participate in future equity financings that will require issuance or reservation of shares authorized by the proposed amendment to our certificate of incorporation.

If this proposal is approved, we will amend our certificate of incorporation by replacing the current Article IV, Section 1 in its entirety as follows:

The amendment will become effective when a certificate of amendment to the certificate of incorporation is filed with the Secretary of State of the State of Delaware.

The Audit Committee has selected PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2014, and has further directed that management submit the selection of an independent registered public accounting firm for ratification by the stockholders at the annual meeting. PricewaterhouseCoopers LLP has been engaged as our independent registered public accounting firm since December 2006. We expect representatives of PricewaterhouseCoopers LLP to be present at the annual meeting, and they will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of our independent registered public accounting firm. However, the Audit Committee is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Amyris and our stockholders.

Ratification of the selection of PricewaterhouseCoopers LLP requires the affirmative vote of a majority of the votes of the holders of shares present in person or represented by proxy and entitled to vote at the annual meeting. Abstentions will be counted toward the vote total for the proposal and will have the same effect as negative votes.

During fiscal years 2013 and 2012, PricewaterhouseCoopers LLP served as our principal accountant for the audit of our annual financial statements and for the review of our financial statements included in our Quarterly Reports on Form 10-Q. The following table represents aggregate fees billed or to be billed to us by PricewaterhouseCoopers LLP for services performed for the fiscal years ended December 31, 2013 and December 31, 2012 (in thousands):

The “Audit Fees” category includes aggregate fees billed in the relevant fiscal year for professional services rendered for the audit of annual financial statements and review of financial statements included in Quarterly Reports on Form 10-Q, and for services that are normally provided in connection with statutory and regulatory filings or engagements for those fiscal years. The Audit Fees for fiscal year 2012 was updated to $1,458,000 from $1,368,000 as previously reported, to reflect the actual amount incurred for services rendered for that period.

The “Audit-Related Fees” category includes aggregate fees billed in the relevant fiscal year for assurance and related services that are reasonably related to the performance of the audit or review of financial statements and that are not reported under the “Audit Fees” category. The audit-related fees above include fees billed in the fiscal years ended December 31, 2013 and 2012 for attest services that are not required by statute or regulation and consultations concerning financial accounting and reporting standards. The audit-related fees above billed in the fiscal year ended December 31, 2012 included due diligence services relating to certain transactions.

The “Tax Fees” category includes aggregate fees billed in the relevant fiscal year for professional services for tax compliance, tax advice and tax planning. The fees related to tax services from PricewaterhouseCoopers LLP in the year ended December 31, 2012 related to annual income tax return review and annual transfer pricing calculations for our subsidiary, Amyris Brasil Ltda.

The “All Other Fees” category includes aggregate fees billed in the relevant fiscal year for products and services provided by the principal accountant other than the services reported under the other categories described above. We did not incur any fees in this category in the years ended December 31, 2013 or 2012.

The Audit Committee’s charter requires it to approve all fees and other compensation paid to, and pre-approve, all audit and non-audit services performed by, the independent registered public accounting firm. The charter permits the Audit Committee to delegate pre-approval authority to one or more members of the Audit Committee, provided that any pre-approval decision is reported to the Audit Committee at its next scheduled meeting. To date, the Audit Committee has not delegated such pre-approval authority.

In determining whether to approve audit and non-audit services to be performed by PricewaterhouseCoopers LLP, the Audit Committee takes into consideration the fees to be paid for such services and whether such fees would affect the independence of the independent registered public accounting firm in performing its audit function. In addition, when determining whether to approve non-audit services to be performed by PricewaterhouseCoopers LLP, the Audit Committee considers whether the performance of such services is compatible with maintaining the independence of PricewaterhouseCoopers LLP in performing its audit function, and confirms that the non-audit services will not include the prohibited activities set forth in Section 201 of the Sarbanes-Oxley Act of 2002. Except for the due diligence services described above under “Audit-Related Fees” and the tax services described above under “Tax Fees” (each of which were pre-approved by the Audit Committee in accordance with its policy) no non-audit services were provided by PricewaterhouseCoopers LLP in 2013 or 2012.

All fees paid to, and all services provided by, PricewaterhouseCoopers LLP during fiscal years 2013 and 2012 were pre-approved by the Audit Committee in accordance with the pre-approval procedures described above.

The Audit Committee has reviewed and discussed with management our audited consolidated financial statements for the fiscal year ended December 31, 2013. The Audit Committee has also discussed with PricewaterhouseCoopers LLP, our independent registered public accounting firm, the matters required to be discussed by the Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

The Audit Committee has received and reviewed the written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 for filing with the Securities and Exchange Commission.

As described in more detail below under “Transactions with Related Persons — Total Transactions,” in July 2012 we amended our collaboration agreement with Total and in connection with such amendment we entered into a Securities Purchase Agreement with Total (which is an affiliate of our director, Philippe Boisseau, and who beneficially owned approximately 17.8% of our outstanding common stock as of December 31, 2013) dated July 30, 2012 (the “Total Purchase Agreement”), pursuant to which Total agreed to purchase $105 million in aggregate principal amount of convertible promissory notes, subject to the terms and conditions set forth in the Total Purchase Agreement. As of July 2013, we had issued $83.3 million in aggregate principal amount of convertible promissory notes to Total pursuant to the Total Purchase Agreement and $21.7 million in aggregate principal amount of senior secured convertible promissory notes remains subject to issuance to Total in accordance with the terms and conditions of the Total Purchase Agreement. These conditions include the provision that Total not elect in July 2014 not to proceed with the collaboration program with us, which we refer to as a “No-Go decision.” We refer in this section to such remaining $21.7 million principal amount of secured convertible promissory notes, as the “Remaining Notes.” The Remaining Notes are issuable in equal $10.85 million installments by no later than July 31, 2014 and January 31, 2015, respectively. See “Transactions with Related Persons — Total Transactions” for additional details on the funding history pursuant to the Total Purchase Agreement and the collaboration agreement.

Pursuant to a letter agreement entered into on April 1, 2014 and dated as of March 29, 2014 between Amyris and Total (the “March 2014 Letter Agreement”), we have agreed to (i) amend the conversion price of the Remaining Notes from $7.0682 to $4.11 (the “New Conversion Price”) subject to stockholder approval of this Proposal 5, (ii) extend the period under which Total may exchange for other Amyris securities certain outstanding convertible promissory notes issued under the Total Purchase Agreement from June 30, 2014 to the later of December 31, 2014 and the date on which Amyris shall have raised $75 million of equity and convertible debt financing (excluding any convertible promissory notes issued pursuant to the Total Purchase Agreement), (iii) eliminate our ability to qualify, in a disclosure letter to Total, certain of the representations and warranties that we must make at the closing of any sale of the Remaining Notes, and (iv) provide Total with monthly reporting on our cash, cash equivalents and short-term investments. In consideration of these agreements, Total has agreed to waive its right not to consummate the closing of the issuance of the Remaining Notes if it decides not proceed with the collaboration and makes a “No-Go” decision with respect thereto, subject to our obtaining stockholder approval of the issuance of the Remaining Notes at the reduced conversion price.

We are asking stockholders to approve the issuance of the Remaining Notes with the New Conversion Price in accordance with NASDAQ Marketplace Rule 5635. The closing of the sale of the initial $10.85 million in aggregate principal amount of Remaining Notes is expected to occur upon satisfaction of certain closing conditions, including stockholder approval of the issuance of the Remaining Notes at the annual meeting, but by no later than July 31, 2014 and the closing of the sale of the remaining $10.85 million in aggregate principal amount of Remaining Notes is expected to occur upon satisfaction of certain closing conditions, including stockholder approval of the issuance of the Remaining Notes at the annual meeting, but by no later than January 31, 2015.

The proposal must receive a “For” vote from the holders of a majority of the shares of common stock casting votes in person or by proxy on Proposal 5 at the Special Meeting. Abstentions will be counted toward the vote total for the proposal and will have the same effect as an “Against” vote for this proposal. Shares represented by executed proxies that do not indicate a vote “For,” “Against” or “Abstain” will be voted by the proxy holders “For” the adoption of the resolution. If you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal.

The Board determined (with Mr. Boisseau abstaining from the discussion and the approval of the Board), upon the recommendation of the Audit Committee that Proposal 5 is advisable and in the best interest of our stockholders and recommended that our stockholders vote in favor of Proposal 5.

In reaching its determination to approve Proposal 5, the Audit Committee and Board, with advice from our management and legal advisors, considered a number of factors, including:

The Audit Committee and the Board also considered the following factors adverse to the issuance of the Remaining Notes:

In view of the variety of factors considered in connection with the evaluation of the issuance of the Remaining Notes with the New Conversion Price and the complexity of these matters, the Board did not find it practicable to, and did not, quantify or otherwise attempt to assign any relative weight to the various factors considered. In addition, in considering the various factors, individual members of the Board may have assigned different weights to different factors.

After evaluating these factors for and against the issuance of the Remaining Notes with the New Conversion Price, and based upon their knowledge of our business, financial condition and prospects, and the view of our management, following the separate approval and the recommendation of the Audit Committee, the Board concluded (with Mr. Boisseau abstaining from the discussion and the approval of the Board) that the issuance of the Remaining Notes with the New Conversion Price is in our best interest and in the best interests of our stockholders, and recommends that all stockholders vote “FOR” the approval of Proposal 5 at the Special Meeting.

Our common stock is listed on NASDAQ and trades under the ticker symbol (AMRS). The rules governing companies with securities listed on NASDAQ require stockholder approval prior to the issuance of securities when the issuance or potential issuance of securities will result in a change of control of Amyris. This requirement is set forth in NASDAQ Marketplace Rule 5635(b). NASDAQ defines a change of control as occurring when, as a result of an issuance, an investor or a group would own, or have the right to acquire 20% or more of the outstanding shares of common stock or voting power, and such ownership or voting power would be the largest ownership position. Under certain circumstances, Proposal 5 could result in Total being the largest owner of common stock of Amyris in an amount greater than 20%. While Total is currently the largest owner of outstanding common stock of Amyris, it may not be the largest owner of outstanding common stock at the time the Remaining Notes are issued, and the Remaining Notes could result in Total being deemed under NASDAQ rules to acquire greater than 20% of our outstanding shares.

By approving Proposal 5, you are approving the proposal for purposes of the requirements under NASDAQ Marketplace Rule 5635.

We have entered into the Total Purchase Agreement under which Total has remaining obligations to purchase up to $21.7 million aggregate principal amount of Remaining Notes with the New Conversion Price. We contemplate selling such Remaining Notes in two equal installments of $10.85 million by no later than July 31, 2014 and January 31 2015, respectively.

We are requesting in this Proposal 5 that our stockholders approve the issuance of the Remaining Notes with the New Conversion Price in a private placement transaction, and the issuance of the Common Stock issuable upon conversion of such Remaining Notes in accordance with NASDAQ Marketplace Rule 5635. The issuance and sale of such Remaining Notes are intended to be exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the Regulation D “safe harbor” provisions of the Securities Act. Set forth below are the material terms of the private placement of the Remaining Notes.

The agreements related to the Total Purchase Agreement, and the context for the funding by Total under that agreement, are described in detail in “The arrangements with Total are described in more detail below in this Proxy Statement under the caption “Transactions with Related Persons — Total Transactions.” We and Total have entered into the Total Purchase Agreement which contains representations and warranties by us and Total to each other and is not intended to provide any other factual information about us.

representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the Total Purchase Agreement as characterizations of the actual state of facts about us and you should read the Total Purchase Agreement together with the other information concerning us that we publicly file in reports and statements with the SEC.

We currently intend to use the net proceeds from the private placement of the Remaining Notes to fund the Biofene collaboration under the terms of the collaboration agreement with Total, as amended.

The private placement of the Remaining Notes with the New Conversion Price could have a dilutive effect on current stockholders who are not participating in such private placement in that the percentage ownership of Amyris held by such current stockholders will decline as a result of the issuance of the common stock issuable upon conversion or exercise of the Remaining Notes. This means also that our current stockholders who are not participating in such private placement will own a smaller interest in us as a result of such private placement and therefore have less ability to influence significant corporate decisions requiring stockholder approval. Issuance of the common stock issuable upon conversion or exercise of the Remaining Notes could also have a dilutive effect on book value per share and any future earnings per share. Dilution of equity interests could also cause prevailing market prices for our common stock to decline.

Because of the conversion price adjustments contained in the Remaining Notes, the exact magnitude of the dilutive effect of the Remaining Notes cannot be conclusively determined. However, the dilutive effect may be material to current stockholders of Amyris. By way of example, assuming the sale and issuance of the full $21.7 million principal amount of Remaining Notes and assuming the New Conversion Price of $4.11, then approximately 5.3 million shares of Amyris’ common stock will be issuable upon conversion of the Remaining Notes, assuming no further adjustment of the conversion price pursuant to the terms of the Remaining Notes, compared to approximately 3.1 million shares that would be issuable upon conversion of such Remaining Notes if the conversion price remained unchanged at $7.0682. Note however that the Remaining Notes, other than with respect to price adjustments for certain dividends and distributions, do not provide for a floor on the downwards adjustments to the conversion price of the Remaining Notes. As a result, the number of shares issuable upon conversion of the Remaining Notes could be significantly larger than this example.

In addition to dilution, the existence of additional convertible debt could, under certain circumstances, discourage or make more difficult our efforts to obtain additional financing.

If the stockholders do not approve this Proposal 5, Total’s obligation to purchase the Remaining Notes will continue to be subject to its right to make a “No-Go decision,” and if it does so it will not be obligated to purchase the remaining $21.7 million of secured convertible promissory notes. In the event that Total were to make a No-Go Decision, we may have to seek to renegotiate financing terms with Total and/or look for alternative capital investments. We may not be able to complete any such renegotiation, nor can we be certain that any such capital investments would be available on favorable terms or at all. Failure to raise additional capital investment would have a material adverse effect on our business and prospects.

If the stockholders do not approve this Proposal 5, we would still be able to issue to Total the Remaining Notes with the original conversion price of $7.0682 if all other closing conditions in the Total Purchase Agreement are met and Total does not make a “No-Go” decision.

When you consider the Board’s recommendation to vote in favor of Proposal 5, you should be aware that our directors and executive officers and existing stockholders may have interests in the issuance of the Remaining Notes that may be different from, or in addition to, the interests of other of our stockholders. In particular, our director Philippe Boisseau is affiliated with Total. Mr. Boisseau is an affiliate of Total and Total’s beneficial ownership of Amyris’ securities as of March 15, 2014 is outlined below in the Section titled Security Ownership of Certain Beneficial Owners and Management.

Because of the conversion price adjustments contained in the Remaining Notes, the exact number of shares issuable to Total on conversion of the Remaining Notes cannot be conclusively determined. The interests to be acquired by Total may be of material interest to Amyris’ stockholders in considering Proposal 5. Assuming the closing conditions for the sale of the Remaining Notes are satisfied and Total purchases its full maximum commitment of $21.7 million principal amount of Remaining Notes and assuming the conversion prices of such notes remain unchanged from the New Conversion Price of $4.11 then approximately 5.3 million shares of Amyris’ common stock will be issuable upon conversion of the Remaining Notes purchased by Total. As a result, Total could significantly increase its ownership interests in Amyris upon conversion of the Remaining Notes.

The issuance of the Remaining Notes was separately approved by the Audit Committee, and Mr. Boisseau was not a member of, nor participated in, any meetings of the Audit Committee in regards to the issuance of the Remaining Notes.

The following table sets forth information with respect to the beneficial ownership of our common stock, as of March 15, 2014, by:

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and generally includes any shares over which the individual or entity has sole or shared voting power or investment power. These rules also treat as outstanding all shares of capital stock that a person would receive upon exercise of stock options held by that person that are immediately exercisable or exercisable within 60 days of the date on which beneficial ownership is determined. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the number of shares beneficially owned and the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. The information does not necessarily indicate beneficial ownership for any other purpose. Except as indicated in the footnotes to this table and pursuant to applicable community property laws, to our knowledge the persons named in the table below have sole voting and investment power with respect to all shares of common stock attributed to them in the table.

Information with respect to beneficial ownership has been furnished to us by each director and executive officer and certain stockholders, and derived from publicly-available SEC beneficial ownership reports on Forms 3 and 4 and Schedules 13G filed by covered beneficial owners of our common stock. Percentage ownership of our common stock in the table is based on 77,038,444 shares of our common stock outstanding on March 15, 2014. Except as otherwise set forth below, the address of the beneficial owner is c/o Amyris, Inc., 5885 Hollis Street, Suite 100, Emeryville, California 94608.

Section 16(a) of the Exchange Act requires our executive officers and directors, and any person or entity who owns more than ten percent of a registered class of our common stock or other equity securities, to file with the Securities and Exchange Commission certain reports of ownership and changes in ownership of our securities. Executive officers, directors and stockholders who hold more than ten percent of our outstanding common stock are required by the Securities and Exchange Commission to furnish us with copies of all Section 16(a) forms they file. Based solely on review of this information and written representations by our executive officers and directors that no other reports were required, we believe that, during 2013, no reporting person failed to file the forms required by Section 16(a) of the Exchange Act on a timely basis.

The following discussion describes and analyzes our compensation for our named executive officers for 2013 and should be read in conjunction with the compensation tables contained elsewhere in this Proxy Statement. Our stockholders adopted a three year interval for “management say on pay” review. Accordingly, our stockholders last voted on the matter at our Annual Meeting in 2011 and approved, on an advisory basis, the compensation of our named executive officers. Our existing compensation policies and decisions are consistent with our compensation philosophy and objectives discussed below and align the interests of our named executive officers with Amyris’ short and long term goals.

The “named executive officers” include our President and Chief Executive Officer, our interim Chief Financial Officer, our two other most highly compensated executive officers (as set forth in the “Summary Compensation Table” below) who were serving as executive officers at the end of 2013, and two members of our management who would have been named executive officers but for the fact that they were no longer executive officers at the end of 2013. Accordingly, this Compensation Discussion and Analysis describes our 2013 executive compensation program and 2013 compensation policies and decisions for:

Ms. McFerson joined us as our Chief Business Officer and was designated as an executive officer in March 2013. Mr. Loeb, who served as our General Counsel since 2012, and prior to that, served as our Senior Corporate Counsel, departed in July 2013 and Mr. Mills, who served as our Chief Financial Officer since 2012 departed in December 2013.

Amyris is an integrated renewable products company focused on providing sustainable alternatives to a broad range of petroleum-sourced products. We use our industrial synthetic biology platform to convert plant sugars into a variety of hydrocarbon molecules — flexible building blocks that can be used in a wide range of products. Our business model is focused on sales of renewable products as well as inflows from collaborations. Our initial portfolio of commercial products has been based on Biofene®, our brand of renewable farnesene, a long-chain branched hydrocarbon. We are commercializing these products both as renewable ingredients in cosmetics, flavors and fragrances, and consumer products, and, with our joint venture partners, as renewable lubricants, diesel and jet fuel. We are also commercializing our initial fragrance oil molecule and expect additional molecules to be produced in the coming years. Collaborations are the other core value creation element of our business model. We engage in research and development collaborations with various partners for new applications or molecules. These collaborations provide us with upfront funding to build strong technical partnerships intended to result in product commercialization and sales. Collaborations also generate a longer-term cash stream as we capture a portion of the gross

margin from the value chain of the product. In 2013, we continued to raise funds through securities offerings to finance our operations until we achieve significant revenues from sales of our renewable products. Our success depends, among other things, on attracting and retaining executive officers with experience and skills in a number of different areas as we continue to drive improvements in our technology platform and production process, pursue and establish key commercial relationships, develop and commercialize products, and establish a reliable supply chain and manufacturing organization.

The primary objectives of our compensation program in 2013 were to:

As discussed above, our business continues to be in an early stage of development with cash management being one key consideration for our strategy and operations. Accordingly, for 2013, we intended to provide a competitive compensation program that would enable us to attract and retain the top executives and employees necessary to develop our business, while being prudent in the management of our cash and equity. Based on this approach, we continued to aim to balance and reward annual and long-term performance with a total compensation package that included a mix of both cash and equity. Our compensation program was intended to align the interests of management, key employees and stockholders and to encourage the creation of stockholder value by providing long-term incentives through equity ownership. We continue to adhere to this general compensation philosophy for 2014.

Our intent and philosophy in designing compensation packages at the time of hiring of new executives was based on providing compensation that we thought was sufficient to enable us to attract the necessary talent within prudent limitations as discussed above. Compensation of our executive officers after the initial period following their hiring has been influenced by the amounts of compensation that we initially agreed to pay them as well as by our evaluation of their subsequent performance, changes in their levels of responsibility, retention considerations, prevailing market conditions, the financial condition and prospects of our company, and our attempt to maintain some level of internal pay parity in the compensation of existing executives relative to the compensation paid to more recently hired executives.

We have compensated our executives with a combination of salaries, cash bonuses and equity awards. We believe this combination of cash and equity, subject to strategic allocation among such components, is largely consistent with the forms of compensation provided by other companies with which we compete for executive talent, and as such is a package that matches the expectations of our executives and of the market for executive talent. We also believe that it provides an appropriate blend of compensation to retain our executives, reward them for performance in the short term and induce them to contribute to the creation of value in Amyris over the long term. We view the different components of our executive compensation as distinct, each serving particular functions in furthering our compensation philosophy and objectives, and together providing a holistic approach to achieving such philosophy and objectives.

including our overall financial performance, the individual performance of the executives in question, the executive’s potential to contribute to our annual and longer-term strategic goals, the executive’s scope of responsibilities and experience, competitive market practices for base salary, and internal pay parity.

We typically grant option awards with four-year vesting schedules (vesting monthly over four years). Stock option grants include a one year “cliff”, where the option vests as to 25% of the shares after one year, and monthly thereafter. Our restricted stock unit awards generally vest and become exercisable over three years on an annual basis. We believe such vesting schedules are generally consistent with the option and restricted stock unit award granting practices of our public company peers. The Leadership Development and Compensation Committee has approved variations to these vesting schedules for options and restricted stock units in connection with new-hire negotiations with senior management candidates, including executive officers.

We grant equity awards to our executive officers in connection with their hiring. The size of initial equity awards has been determined based on the executive’s position with us and takes into consideration the executive’s base salary and other compensation as well as an analysis of the grant and compensation practices of the companies that participate in the survey that we have reviewed in the past (described in more detail below) in connection with establishing our overall compensation policies. The initial equity awards are generally intended to provide the executive with an incentive to build value in the organization over an extended period of time, while remaining consistent with our overall compensation philosophy. Insofar as we have to date incurred operating losses and consumed substantial amounts of cash in our operations, and to compensate for cash salaries and cash bonus opportunities that were, in certain cases, lower than those offered by other employers, we have sought to attract executives to join us by granting equity awards that would have the potential to provide significant value if we are successful.

We may also grant additional equity awards in recognition of commendable performance and in connection with a significant change in responsibilities. Further, equity awards are a component of the

annual compensation package of our executive officers. In 2013, the Leadership Development and Compensation Committee granted equity awards based on input from management regarding performance, retention and other considerations. In approving awards, the Leadership Development and Compensation Committee has taken into account various factors, including the responsibilities, past performance and anticipated future contribution of the executive officer, the executive’s overall compensation package and the executive’s existing equity holdings in Amyris.

Our Leadership Development and Compensation Committee determined, through discussions with management and Compensia at committee meetings held in February 2013 and February 2014, that our policies and practices of compensating our employees, including executive officers, are not reasonably likely to have a material adverse effect on us. The assessments conducted by the committee focused on the key terms of our bonus payments and equity compensation programs in 2013, and our plans for such programs in 2014. Among other things, the committee focused on whether our compensation programs created incentives for risk-taking behavior and whether existing risk mitigation features were sufficient in light of the overall structure and composition of our compensation programs. Among other things, the Committee considered the following aspects of our overall compensation program:

Based on these considerations the committee determined that our compensation programs, including our executive and non-executive compensation programs, provide an appropriate balance of incentives and do not encourage our executives or other employees to take excessive risks or otherwise create risks that are likely to have a material adverse effect on us.

similarly situated companies. In 2013, Compensia assisted in the preparation of compensation materials for executive compensation proposals in advance of Leadership Development and Compensation Committee meetings, including 2013 compensation levels for executives and the design of our cash bonus, equity, severance and change of control programs and other executive benefit programs. Compensia also reviewed and advised the Leadership Development and Compensation Committee on compensation materials relating to executive compensation prepared by management for committee consideration. In addition, in the fourth quarters of 2011and 2012, Compensia assisted the Leadership Development and Compensation Committee in developing and adopting an updated compensation peer group for 2012 and 2013 (discussed below). The Leadership Development and Compensation Committee retained Compensia again in the fourth quarter of 2013 to provide assistance with respect to our 2014 compensation planning, including updates to the compensation peer group.

Compensia, under the direction of the Leadership Development and Compensation Committee, may continue to periodically conduct a review of the competitiveness of our executive compensation programs, including base salaries, cash bonus compensation, equity awards and other executive benefits, by analyzing the compensation practices of companies in our compensation peer group, as well as data from third-party compensation surveys. Generally, the Leadership Development and Compensation Committee uses the results of such analyses to assess the competitiveness of our executives’ total compensation, and to determine whether each element of such total compensation is properly aligned with reasonable and responsible practices among our peers.

The Leadership Development and Compensation Committee also retained Compensia for assistance in reviewing and deciding on director compensation programs when the program was originally adopted in late 2010, and to provide market data and materials to management and the committee.

Under the charter of our Leadership Development and Compensation Committee, the Board delegated to the committee the authority and responsibility to discharge the responsibilities of the Board relating to compensation of our executive officers. This includes, among other things, review and approval of the compensation of our executive officers and of the terms of any compensation agreements with our executive officers. Please see the additional detail regarding the functions and composition of the Leadership Development and Compensation Committee above in this Proxy Statement under the caption “Proposal 1 — Election of Directors — Committees of the Board.”

In general, our Leadership Development and Compensation Committee is responsible for the design, implementation and oversight of our executive compensation program. In accordance with its charter, the committee determines the annual compensation of our Chief Executive Officer and other executive officers and reports its compensation decisions to the Board. The committee also administers our equity compensation plans, including our 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan. Generally, our Chief Executive Officer, with input from our Chief Human Resources Officer and from Compensia, makes recommendations to the Leadership Development and Compensation Committee regarding the compensation for our named executive officers (other than with respect to compensation of our Chief Executive Officer) based on his assessment of company results, each executive’s contributions to these results, his or her progress toward achieving his or her individual goals, and his or her demonstration of Amyris core values. The Leadership Development and Compensation Committee’s decisions regarding our Chief Executive Officer’s compensation are based on its assessment of company results, his contributions to these results, his progress towards achieving his individual goals, competitive market data, and input from Compensia.

In November 2013, the Leadership Development and Compensation Committee approved updates to the Peer Group for 2014. Similar to our approach for the 2013 Peer Group, we identified potential peers by screening of publicly-traded U.S.-based companies of similar size to us (in revenues and market capitalization) from related industries (biotechnology, Oils, Gas & Fuels, Home & Personal Products specialty chemicals). The Leadership Development and Compensation Committee determined that, for 2014, the Peer Group should be adjusted to give more consideration to specialty chemical and bio-industrial peers, and to reduce the weight placed on alternative energy, pharma and dissimilar biotechnology companies. In addition, the peer group adopted for 2014 eliminated certain companies that were deemed less relevant to Amyris as a result of market capitalization, revenues or other factors. As a result, for 2014 Ceres Global Ag Corp., Clean Energy Fuels Corp., Ormat Technologies, Inc., Verenium Corporation, Alnylam Pharmaceutials, Inc. and Isis Pharmaceuticals, Inc. were removed from the Peer Group, and American Pacific Corporation, BioAmber, Inc., Intrexon Corporation, Renewable Energy Group, Inc., Senomyx, Inc. were added to the Peer Group.

In addition to reviewing analysis of the compensation practices of the Peer Group, the Leadership Development and Compensation Committee looks to the collective experience and judgment of its members and advisors in determining total compensation and the various compensation components provided to executive officers. While the Leadership Development and Compensation Committee does not believe that the Peer Group data is appropriate as a stand-alone tool for setting executive compensation due to the unique nature of our business, it believes that this information is a valuable reference source during its decision-making process.

In making compensation decisions for executive officers for 2013, we also referred to broader compensation survey data from the Radford Global Life Sciences Survey. We have used similar surveys for reference in establishing our 2014 compensation programs.

associated need to conserve our cash while we ramp up our operations. Equity has been a critical and prominent component in our overall compensation package and we believe that it will remain an important tool for attracting, retaining and motivating our key talent by providing an opportunity for wealth creation as a result of Amyris’ success, particularly while we are growing our business and targeting the 40​th percentile for total cash compensation. As a result, we have generally targeted equity compensation levels greater than or equal to the 75​th percentile of the competitive market for equity compensation based on the Peer Group, supplemented by data from surveys, and taking into consideration Leadership Development and Compensation Committee approved targeted annual burn rate.

In April 2013, the Leadership Development and Compensation Committee reviewed an analysis by Compensia of our executive compensation levels. Based on data compiled from the Peer Group, supplemented by survey data, this analysis indicated that the target total cash compensation for our executives (current base salary plus target incentive opportunity) were at or above the 40​th percentile of the competitive market. Several of these compensation levels were set based on individual negotiations in connection with hiring or other circumstances, as well as Leadership Development and Compensation Committee decisions, with input from the Chief Executive Officer, based on scope of responsibility and performance, which led to the variation from the 40​th percentile. The committee approved annual equity awards to executives in May 2013 based primarily on the retention value of existing awards held by executives (taking into account option exercise prices and the prevailing market values for our common stock), given that it found most executives were below the 75​th percentile of the competitive market in their unvested value.

For 2014, we expect to continue to target the same percentiles as we have in prior years using our updated Peer Group and similar industry survey data, which approach the Leadership Development and Compensation Committee approved in November 2013.

In December 2013, Mr. Diniz was appointed as our interim Chief Financial Officer and the Leadership Development and Compensation Committee reviewed his compensation. In connection with such review, certain adjustments were made to Mr. Diniz’ cash compensation. Among other things, Mr. Diniz’ employment offer letter set his annual base salary at $400,000, but he has historically received an annual salary through our Brazilian subsidiary’s payroll in Brazilian reais. As a result, Mr. Diniz’ past salary amounts have not equated to $400,000 per year. Therefore, in December 2013, we agreed to provide Mr. Diniz a one-time true-up payment of $110,049 for the exchange rate discrepancies from March 2011 through December 2013. Starting in January 2014, we commenced providing Mr. Diniz a monthly true-up to ensure his local salary paid in Brazilian reais remains commensurate with the $33,333 per month we committed to in his employment offer letter.
