Only stockholders of record at the close of business on April 21, 2023, will be entitled to vote at the Annual Meeting. On this record date, there were [  ] shares of common stock outstanding and entitled to vote.

If on April 21, 2023, your shares were registered directly in your name with SCYNEXIS’s transfer agent, American Stock Transfer & Trust Company, then you are a stockholder of record. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

If on April 21, 2023, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and the proxy materials are being sent to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account, as provided in your voting instruction form. You are also invited to attend the Annual Meeting. Many stockholders of record will provide you with a 16-digit control number via email or in your voting instruction form in order to attend and vote your shares at the Annual Meeting. If you wish to vote your shares at the Annual Meeting, please contact your broker, bank or other agent for instructions on how to vote your shares.

There are six matters scheduled for a vote:

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the proxy card to vote on those matters in accordance with their best judgment.

You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

If you are a stockholder of record, you may vote your shares at the Annual Meeting. If you do not wish to vote your shares at the Annual Meeting or you will not be attending the Annual Meeting, you may vote by proxy, by telephone or over the internet. To vote by proxy on the internet, go to www.proxyvote.com to complete an electronic proxy card. To vote by proxy by telephone, dial 1-800-690-6903, the toll-free number shown on the proxy card, and follow the recorded instructions. Alternatively, you may complete, sign and return the proxy card using the enclosed envelope provided with the proxy card. If you vote by proxy over the phone or the internet, you will be asked to provide the control number from the proxy card. If you vote by proxy, your vote must be received by 11:59 p.m. Eastern Time on June 13, 2023, to be counted.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers.

If you are a beneficial owner of shares held in street name, you should have received a voting instruction form from the broker, bank or other nominee that is the record owner of your shares rather than from us. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, if your broker provides telephone or internet voting, you may vote by telephone or over the internet as instructed by your broker or bank. To vote at the Annual Meeting, follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization for instructions on how to vote your shares. If you wish to vote your shares at the Annual Meeting, please contact your broker, bank or other agent for instructions on how to vote your shares.

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 21, 2023.

If you are a stockholder of record and do not vote by completing your proxy card, over the internet or in person at the annual meeting, your shares will not be voted.

If you are a beneficial owner and do not instruct your broker, bank or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange (“NYSE”) deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the NYSE, “non-routine matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1, 3, 5 and 6 without your instructions but may vote your shares on Proposal 2. We have not been advised as to whether the NYSE will deem the proposal to approve an amendment to our Amended and Restated Certificate of Incorporation, as amended, to limit the liability of officers of SCYNEXIS as permitted pursuant to recent amendments to the Delaware General Corporation Law, as “routine” or “non-routine”; however, we believe that the NYSE will deem this proposal as a “non-routine” matter. Since we have not been advised as to how the NYSE will designate this proposal, we recommend that stockholders cast their votes by proxy to ensure that their shares are voted in the manner they wish.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, “For” the election of all our seven nominees for director, “For” the ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the independent registered public accounting firm of SCYNEXIS for its fiscal year ending December 31, 2023, “For” the advisory approval of the compensation of our named executive officers as disclosed in this proxy statement, “For” the approval of an amendment to our Amended and Restated Certificate of Incorporation, as amended, to limit the liability of officers, “For” the approval of our 2023 Equity Incentive Plan, and “For” the approval of our Amended and Restated 2014 Employee Stock Purchase Plan.

If any other matter is properly presented at the Annual Meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment, if permitted under SEC rules.

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage

firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. We have hired Morrow Sodali LLC, 333 Ludlow Street, 5 Floor, South Tower, Stamford, CT 06902, to aid in the solicitation of proxies for a fee of $8,500, plus reasonable out-of-pocket expenses.

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

Yes. You can change your vote or revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may change your vote or revoke your proxy in any one of the following ways:

Your most current proxy card or internet proxy is the one that is counted.

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by January [ ], 2024, to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13th Floor, Jersey City, New Jersey, 07302; provided, however, that if our 2024 annual meeting of stockholders is held before May 15, 2024, or after July 14, 2024, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2024 annual meeting of stockholders. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director pursuant to our Bylaws, you must provide specified information in writing to our Corporate Secretary at the address above by not later than March 16, 2024, nor earlier than the close of business on February 15, 2024, except that if our 2024 annual meeting of stockholders is held before May 15, 2024, or after July 14, 2024, notice to be timely must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made. You are also advised to review our Bylaws, which contain a description of the information required to be submitted as well as additional requirements about advance notice of stockholder proposals and director nominations.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 15, 2024; provided, however, that, in the event that the annual meeting is held before May 15, 2024, or after July 14, 2024, for your notice to be timely, it must be so received by our Corporate Secretary not earlier than the close of business on the date the later of sixty (60) days prior to such annual meeting and the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by us.

Please refer to our bylaws and Rule 14a-19 under the Exchange Act for additional information and requirements regarding stockholder proposals and director nominations. We will not consider any proposal or nomination that is not timely or otherwise does not meet our bylaws and the SEC’s requirements for submitting a proposal or nomination, as applicable. We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal or nomination that does not comply with these and any other applicable requirements.

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count: with respect to the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and with respect to other proposals, votes “For,” “Against,” abstentions and, if applicable, broker non-votes. The effect of abstentions and broker non-votes, if any, on whether a proposal is approved is set forth under “How many votes are needed to approve each proposal?” below.

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present in person at the Annual Meeting or represented by proxy. On the record date, there were [  ] shares outstanding and entitled to vote. Thus the holders of [  ] shares must attend or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you attend the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairman of the Annual Meeting or the holders of a majority of the shares present in person at the Annual Meeting or represented by proxy may adjourn the Annual Meeting to another date.

We expect to announce the preliminary voting results at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

The proxy statement and annual report to stockholders are available at www.proxyvote.com.

SCYNEXIS’s Board of Directors (the “Board”) is elected annually at each annual meeting. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy shall serve for the remainder of the year, and until the director’s successor is duly elected and qualified. This includes vacancies created by an increase in the number of directors.

The Board currently has seven members, all of whose terms of office expire at the Annual Meeting. Our Nominating and Corporate Governance Committee recommended, and our Board approved, the nomination of seven nominees for election at the Annual Meeting. Proxies may not be voted for a greater number of persons than the number of nominees named. All of our nominees were elected by our stockholders at our 2022 annual meeting of stockholders, with the exception of Dr. David Angulo, who was appointed by the Board as a director upon becoming our chief executive officer on January 1, 2023, to fill the vacancy created when our former chief executive officer, Dr. Marco Taglietti, retired at the end of 2022.

Our seven nominees, their ages as of May 1, 2023, and their position currently held with SCYNEXIS, are as follows:

If elected at the Annual Meeting, each of these nominees would be elected and qualified to serve until the 2024 annual meeting of stockholders and until his or her successor is duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is our policy to encourage directors and nominees for director to attend the Annual Meeting. All of our current directors attended the 2022 annual meeting of stockholders.

Directors are elected by a plurality of the votes of the holders of shares present in person or by proxy and entitled to vote on the election of directors. Unless marked otherwise we will vote proxies returned to us for the nominees named above. The seven nominees receiving the highest number of affirmative votes will be elected. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

This Proposal 1 is to elect our seven nominees nominated as directors. The biographies of each of the nominees below contain information regarding the person’s service as a director, business experience, director positions held currently or at any time during the last five years, information regarding involvement in certain legal or administrative proceedings, if applicable, and the experiences, qualifications, attributes and skills of each director, including those that led to the Nominating and Corporate Governance Committee and the Board’s conclusion that the director should continue to serve as a director of SCYNEXIS.

In the last ten years none of our directors were executive officers of a corporation that declared bankruptcy within two years of the director being an executive officer of that corporation other than Mr. Hastings, who was an executive officer of Unilife Corporation when it filed for voluntary bankruptcy in April 2017. There are no family relationships among our directors and executive officers.

The Board Diversity Matrix below provides the diversity statistics for our Board of Directors.

As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of our Board must qualify as “independent,” as affirmatively determined by our Board. The Board consults with SCYNEXIS’s counsel to ensure that the Board’s determinations are consistent with all relevant securities laws and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of their family members, and SCYNEXIS, its senior management and its independent registered public accounting firm, the Board affirmatively has determined that all of the directors during 2022 and currently, other than Dr. Marco Taglietti, our president and chief executive officer during 2022, and Dr. Angulo, our current president and chief executive officer, are independent directors within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board found that none of the directors or nominees for director other than Dr. Angulo had a material or other disqualifying relationship with SCYNEXIS.

The Board has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The following table provides membership information and meeting information for 2022 for each of the Audit, Compensation, and Nominating and Corporate Governance Committees:

Below is a description of each committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable rules and regulations regarding “independence” and that each member is free of any relationship that would interfere with his individual exercise of independent judgment with regard to SCYNEXIS. Each of these committees has a charter, and the charters for each of these committees are available on our website at www.scynexis.com.

Our Audit Committee currently consists of Ann F. Hanham, Ph.D., David Hastings, and Philippe Tinmouth, each of whom satisfies the independence requirements under the Nasdaq Global Market listing standards and Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, or the Exchange Act. Our Board has determined that Mr. Hastings is an “audit committee financial expert” within the meaning of SEC regulations.

Mr. Hastings is the Chair of the Audit Committee. Each member of our Audit Committee can read and understand fundamental financial statements in accordance with Audit Committee requirements. In arriving at this determination, our Board has examined each Audit Committee member’s scope of experience and the nature of their employment in the corporate finance sector.

Our Audit Committee oversees our corporate accounting and financial reporting process. The Audit Committee has the following responsibilities, among other things, as set forth in the Audit Committee charter:

Our Compensation Committee currently consists of Armando Anido, Steven C. Gilman, Ph.D., and Guy Macdonald, each of whom our Board has determined to be independent under the Nasdaq Global Market listing standards.

Our Compensation Committee reviews and recommends policies relating to compensation and benefits of our officers and employees. The Compensation Committee has the following responsibilities, among other things, as set forth in the Compensation Committee’s charter:

We expect that the Compensation Committee will generally meet four times annually and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the CEO. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors

or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of SCYNEXIS, and provides that the Compensation Committee may form and delegate authority to subcommittees as appropriate. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of SCYNEXIS, advice and assistance from internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq, the Compensation Committee engaged Radford and Pearl Meyer as independent compensation consultants through May 2022 and since June 2022, respectively. Radford served, and Pearl Meyer serves, as a compensation resource available to the Compensation Committee on an hourly basis. As part of their engagements, the independent compensation consultants were requested by the Compensation Committee to develop a grant value method for equity compensation of employees and directors for consideration by the Compensation Committee and to review the competitiveness of director compensation based on a comparative group of biotechnology and pharmaceutical companies. The independent compensation consultants were also requested by the Compensation Committee to review compensation of senior executives in comparison with other biotech companies to advise the Compensation Committee on compensation benchmarking, to review equity guideline recommendations and to assist in developing an overall employee compensation structure for consideration by the Compensation Committee.

Our Nominating and Corporate Governance Committee currently consists of Armando Anido, Steven C. Gilman, Ph.D., and Ann F. Hanham, Ph.D., and each of whom our Board has determined to be independent under the Nasdaq Global Market listing standards.

Our Nominating and Corporate Governance Committee makes recommendations regarding corporate governance, the composition of our Board, identification, evaluation and nomination of director candidates and the structure and composition of committees of our Board. The Nominating and Corporate Governance Committee has the following responsibilities, among other things, as set forth in the Nominating and Corporate Governance Committee’s charter:

In considering whether to recommend any candidates for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by stockholders, the Nominating and Corporate Governance Committee considers the candidate’s ability to read and understand financial statements, age, personal integrity and ethics, relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the company, demonstrated experience in his or her field, ability to exercise sound business judgment, and having the commitment to rigorously represent the long-term interests of the company’s stockholders. In addition, when conducting its assessment, the Nominating

and Corporate Governance Committee considers any criteria for director qualifications set by the Board, as well as diversity, skills, and such other factors as it deems appropriate given the current needs of the Board and the company to maintain a balance of knowledge, experience and capability. When considering diversity, the Board and Nominating and Corporate Governance Committee views “diversity” as diversity of experience and expertise. The Board and Nominating and Corporate Governance Committee believe that having a Board diverse in experience and expertise enables the Board, as a body, to have the broad range of requisite expertise and experience to guide the company and management and to fulfill its role of oversight and stewardship. However, neither the Board nor the Nominating and Corporate Governance Committee has developed a policy with respect to diversity in identifying nominees for director, other than to consider diversity when assessing nominees.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews such directors’ overall service to the company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee should be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee has engaged a professional search firm several times and that firm has performed a recruiting function by compiling lists of potential candidates, evaluating and interviewing the most appropriate candidates, and presenting to the Nominating and Corporate Governance Committee the most qualified. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider such candidates’ qualifications and then recommends a nominee to the Board by majority vote.

To date, the Nominating and Corporate Governance Committee has not received a timely recommended director nominee from a stockholder or stockholders holding more than 5% of our voting stock.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders who demonstrate, by written documentation, satisfactory to the Nominating and Corporate Governance Committee, that such stockholders hold outstanding shares of the company. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether the candidate was recommended by a stockholder or not. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at an annual meeting may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 1 Evertrust Plaza, 13th Floor, Jersey City, New Jersey, 07302 no earlier than 120 days before, nor later than 90 days before, the first anniversary of the previous year’s annual meeting. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, and a description of the proposed nominee’s qualifications as a director. 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.

The Board’s leadership structure is a separate Chairman of the Board and Chief Executive Officer. Mr. Guy Macdonald was appointed as our Chairman in June 2015. The Chairman has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. The Board believes that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of SCYNEXIS, and is appropriate for SCYNEXIS. In addition, the Board believes that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether

management’s actions are in the best interests of the company and its stockholders. As a result, the Board believes that having an independent Chairman can enhance the effectiveness of the Board as a whole.

The Board has an active role, as a whole and also at the committee level, in overseeing management of the company’s risks. The Board regularly reviews information regarding the company’s credit, liquidity and operations, as well as the risks associated with each. The Audit Committee’s charter mandates the Audit Committee to review and discuss with management, and the company’s independent registered public accounting firm, as appropriate, the company’s major financial risk exposures and the steps taken by management to monitor and control these exposures. The Compensation Committee is responsible for overseeing the management of risks relating to the company’s executive compensation plans and arrangements. The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks.

With the help of the Compensation Committee’s independent compensation consulting firm, Pearl Meyer, the Compensation Committee has reviewed the company’s compensation policies and practices as they relate to risk management for all employees, including executive officers. Following such review, the Compensation Committee determined that risks arising from the company’s compensation policies and practices for its employees are not reasonably likely to have a material adverse effect on the company.

The Board met six times in 2022. All directors attended at least 75% of the aggregate number of the meetings of the Board and the committees on which they served, held during the portion of the last fiscal year for which they were directors or committee members in 2022.

As required under applicable Nasdaq listing standards, in fiscal year 2022, SCYNEXIS’s independent directors met in regularly scheduled executive sessions at which only independent directors were present.

SCYNEXIS’s Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed as follows: Scott Sukenick, General Counsel, SCYNEXIS, Inc., 1 Evertrust Plaza, 13th Floor, Jersey City, New Jersey, 07302, or via email to scott.sukenick@scynexis.com. The communications will be reviewed by the General Counsel. The General Counsel will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication is unduly frivolous, hostile, threatening or similarly inappropriate, in which case, the General Counsel shall discard the communication.

SCYNEXIS has adopted the SCYNEXIS, Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on our website, which is www.scynexis.com, and available in print to any stockholder who requests it. Requests for printed copies of the Code of Business Conduct and Ethics can be made by writing to Attn: Corporate Secretary, SCYNEXIS, Inc., 1 Evertrust Plaza, 13th Floor, Jersey City, New Jersey, 07302. If SCYNEXIS makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, SCYNEXIS will promptly disclose the nature of the amendment or waiver on its website.

SCYNEXIS believes that speculative and short-term trading of its securities is not appropriate for its employees or directors and thus provides, in its insider trading policy, that no employee, director or covered consultant may engage in short sales, transactions in put or call options or other derivative securities based on SCYNEXIS securities, hedging transactions, margin accounts, pledges, or other inherently speculative transactions with respect to SCYNEXIS equity at any time.

The Audit Committee of the Board of Directors has selected Deloitte & Touche LLP as SCYNEXIS’s independent registered public accounting firm for the fiscal year ending December 31, 2023, and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Deloitte & Touche LLP has audited SCYNEXIS’s financial statements since fiscal year 2000. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

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

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of Deloitte & Touche LLP.

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2022, and December 31, 2021, by Deloitte & Touche LLP, SCYNEXIS’s independent registered public accounting firm (in thousands).

All fees described above were approved by the Audit Committee.

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, Deloitte & Touche LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by Deloitte & Touche LLP is compatible with maintaining the principal accountant’s independence.

Management is responsible for SCYNEXIS’s internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of SCYNEXIS’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) to obtain reasonable assurance that SCYNEXIS’s consolidated financial statements are free from material misstatement and expressing an opinion on the conformity of such financial statements with accounting principles generally accepted in the United States. We are responsible for overseeing and monitoring Deloitte & Touche LLP’s auditing process on behalf of the Board of Directors.

In this context, the Audit Committee has reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 31, 2022, with management and Deloitte & Touche LLP. The Audit Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by the applicable requirements of the PCAOB and the Securities and Exchange Commission. The Audit Committee has also received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence.

Based on its discussions with management and the independent registered public accounting firm, the Audit Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in SCYNEXIS’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, SCYNEXIS’s stockholders are entitled to vote to approve, on an advisory basis, the compensation of the named executive officers (those executive officers appearing in the “Summary Compensation Table” below), or “NEOs,” commonly referred to as a “say-on-pay vote,” as disclosed in this proxy statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of SCYNEXIS’s NEOs and the compensation philosophy, policies and practices described in this proxy statement. The compensation of SCYNEXIS’s NEOs subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement.

Before you vote on this proposal, we urge you to read the executive compensation information (including the compensation tables and the accompanying footnotes and narrative) set forth in this Proxy Statement. As we describe in these disclosures, our compensation philosophy strives to align the interests of our employees and board members with those of our stockholders. As part of this philosophy, we emphasize equity over cash compensation. We seek to ensure that the total compensation paid to our executive officers is reasonable and competitive.

Accordingly, our Board of Directors is asking stockholders to indicate their support for the compensation of SCYNEXIS’s named executive officers by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to SCYNEXIS’s named executive officers, as disclosed in the proxy statement pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”

This is an advisory vote and the results will not be binding; however, we, our Board of Directors, and the Compensation Committee value the views of our stockholders and intend to consider the outcome of this vote when making future compensation decisions of our NEOs and on our executive compensation principles, policies, and procedures and will evaluate whether any actions are necessary to address the stockholders’ concerns.

The Board has unanimously adopted a resolution to amend our Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), subject to stockholder approval, to provide for the elimination or limitation of monetary liability of officers of SCYNEXIS for breach of the duty of care. Article VI.A. of our Certificate of Incorporation currently provides for the company to limit the monetary liability of directors in certain circumstances pursuant to and consistent with Section 102(b)(7) of the General Corporation Laws of Delaware (“DCGL”). Effective August 1, 2022, Section 102(b)(7) of the DCGL was amended to permit a company’s certificate of incorporation to include a provision eliminating or limiting monetary liability for certain senior corporate officers for breach of the fiduciary duty (“Section 102(b)(7) Amendment”).

Accordingly, our Board is asking our stockholders to approve the proposal to add to our Certificate of Incorporation a new Article VIII, to read as follows:

No officer of the Corporation shall have any personal liability to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as an officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Any amendment, repeal or modification of this Article VIII, or the adoption of any provision of this Certificate of Incorporation inconsistent with this Article VIII, shall not adversely affect any right or protection of an officer of the Corporation with respect to any act or omission occurring prior to such amendment, repeal, modification or adoption. If the DGCL is amended after approval by the stockholders of this Article VIII to authorize corporate action further eliminating or limiting the personal liability of officers, then the liability of an officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

If the stockholders approve this proposal at the Annual Meeting, we will file a Certificate of Amendment to our Certificate of Incorporation (the “Amendment”) effecting the Amendment. In accordance with the DGCL, however, our Board may elect to abandon the Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval of the Amendment.

The Board desires to amend its Certificate of Incorporation to maintain provisions consistent with the governing statutes contained in the DCGL. Prior to the Section 102(b)(7) Amendment, Delaware law has permitted Delaware corporations to exculpate directors from personal liability for monetary damages associated with breaches of the duty of care, but that protection did not extend to a Delaware corporation’s officers. Consequently, stockholder plaintiffs have employed a tactic of bringing certain claims that would otherwise be exculpated if brought against directors, against individual officers to avoid dismissal of such claims. The Section 102(b)(7) Amendment was adopted to address inconsistent treatment between officers and directors and address rising litigation and insurance costs for stockholders.

As is currently the case with directors under our Certificate of Incorporation, this provision would not exculpate officers from liability for breach of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit. Nor would this provision exculpate such officers from liability for claims brought by or in the right of the corporation, such as derivative claims. The Board believes it is necessary to provide protection to officers to the fullest extent permitted by law in order to attract and retain top talent. This protection has long been afforded to directors, and accordingly, the Board believes that this Proposal which would extend exculpation to officers, as specifically permitted by the Section 102(b)(7) Amendment, is fair and in the best interests of the company and its stockholders.

The affirmative vote of the holders of a majority of the shares of the common stock outstanding on the record date will be required to approve this Proposal 4. As a result, abstentions and broker non-votes will have the same effect as “Against” votes.

We are asking our stockholders to approve the SCYNEXIS, Inc. 2023 Equity Incentive Plan, or the 2023 Plan, at the annual meeting. The 2023 Plan was approved by our Board of Directors, or Board, on April 14, 2023, subject to approval by our stockholders. The 2023 Plan is intended to be the successor to the SCYNEXIS, Inc. 2014 Equity Incentive Plan, or the 2014 Plan.

Currently, we maintain the 2014 Plan to grant stock options, restricted stock units and other stock awards in order to provide long-term incentives to our employees, consultants, and directors. Our board of directors decided to adopt and seek approval for the 2023 Plan as the successor to and continuation of the 2014 Plan because it wanted to update the plan provisions to conform with current market practices.

Approval of the 2023 Plan by our stockholders will allow us to continue to grant stock options, restricted stock unit awards and other awards at levels determined appropriate by our Board or Compensation Committee. The 2023 Plan will also allow us to utilize a broad array of equity incentives in order to secure and retain the services of our employees, directors, and consultants, and to provide long-term incentives that align the interests of our employees, directors, and consultants with the interests of our stockholders.

Subject to adjustment for certain changes in our capitalization, if this Proposal 5 is approved by our stockholders, the aggregate number of shares of our common stock that may be issued under the 2023 Plan will not exceed the sum of (i) the number of unallocated shares remaining available for the grant of new awards under the 2014 Plan as of the effective date of the 2023 Plan (which is equal to 590,207 shares as of March 31, 2023), (ii) 6,500,000 new shares, and (iii) certain shares subject to outstanding awards granted under the 2014 Plan that may become available for grant under the 2023 Plan as such shares become available from time to time (as further described below in “Description of the 2023 Equity Incentive Plan – Authorized Shares”).

Our Board believes that our future success depends, in large part, on our ability to maintain a competitive position in attracting, retaining, and motivating key personnel, non-employee directors, consultants and advisors. The Board believes that the issuance of equity awards is a key element underlying our ability to attract, retain and motivate key personnel, non-employee directors, consultants, and advisors, and better aligns the interests of our personnel, non-employee directors, consultants, and advisors with those of our stockholders. The 2023 Plan will allow us to continue to provide performance-based incentives to our eligible employees, non-employee directors, consultants, and advisors. Therefore, the Board believes that the 2023 Plan is in the best interests of the company and its stockholders and recommends a vote in favor of this Proposal 5.

The Board believes that the 2023 Plan is necessary to ensure that the number of shares available for issuance is sufficient to allow us to continue to attract and retain the services of talented individuals essential to our long-term growth and financial success. Our Board strongly believes that the issuance of equity awards is a key element underlying our ability to attract, retain and motivate our employees, including our executives, and our consultants and advisors, and is a substantial contributing factor to our success and the growth of our business. So far we have relied significantly on equity incentives in the form of stock option awards and restricted stock unit awards to attract and retain key employees, and we believe that equity incentives are necessary for us to remain competitive in the marketplace for executive talent and other employees. The adoption of the 2023 Plan and new share reserve of 7,090,207 shares will address the depletion to the 2014 Plan’s available share reserve that has occurred as a result of the recent growth of the company. In particular, an immediate increase to the share reserve will provide the Board with flexibility to continue to make annual equity awards to eligible employees and new hires through the next year and will allow us to remain competitive in the marketplace.

We continue to believe that equity awards such as stock options and restricted stock units are a vital part of our overall compensation program. Our compensation philosophy reflects broad-based eligibility for equity incentive awards, and we grant awards to substantially all of our employees. However, we recognize that equity awards dilute existing stockholders, and, therefore, we must responsibly manage the growth of our equity compensation program. We are committed to effectively monitoring our equity compensation share reserve, including our “burn rate,” to ensure that we maximize stockholders’ value by granting the appropriate number of equity incentive awards necessary to attract, reward, and retain employees and non-employee directors. The tables below show our responsible overhang and burn rate percentages.

If the 2023 Plan is approved by our stockholders, we expect to have approximately 7,090,207 shares available for grant after our annual meeting (based on shares available as of March 31, 2023), which we anticipate being a pool of shares sufficient for grants through first quarter of 2023, and necessary to provide a predictable amount of equity for attracting, retaining, and motivating employees. The size of our request is also reasonable in light of the equity granted to our employees and directors over the past year, which is comparatively lower than the majority of our peer companies.

The 2023 Plan includes provisions that are designed to protect our stockholders’ interests and to reflect corporate governance best practices including:

If this Proposal 5 is approved by our stockholders, the 2023 Plan will become effective as of the date of the annual meeting and no additional awards will be granted under the 2014 Plan (although all outstanding awards granted under the 2014 Plan will continue to be subject to the terms and conditions as set forth in the agreements evidencing such awards and the terms of the 2014 Plan). In the event that our stockholders do not approve this Proposal 5, the 2023 Plan will not become effective and the 2014 Plan will continue to be effective in accordance with its terms.

The following table provides certain additional information regarding our use of equity awards:

The company monitors stockholder dilution by tracking the number of shares subject to equity awards that it grants annually commonly referred to as the burn rate. Burn rate shows how rapidly a company is depleting its shares reserved for equity compensation awards and is defined for this purpose as the number of equity awards granted as incentives during the year divided by the weighted average number of shares of common stock outstanding during the year. The company has calculated the burn rate for the past three years, as set forth in the following table:

The material features of the 2023 Plan are described below. The following description of the 2023 Plan is a summary only and is qualified in its entirety by reference to the complete text of the 2023 Plan. Stockholders are urged to read the actual text of the 2023 Plan in its entirety, which is attached as Appendix A of the proxy statement filed with the SEC.

The 2023 Plan is intended to be the successor to the 2014 Plan. If the 2023 Plan is approved by our stockholders, no additional awards will be granted under the 2014 Plan.

Awards. Our 2023 Plan will provide for the grant of incentive stock options, or ISOs, within the meaning of Section 422 of the Code to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit, or RSU, awards, performance awards and other forms of awards to employees, directors, and consultants, including employees and consultants of our affiliates.

Authorized Shares. Initially, the maximum number of shares of our common stock that may be issued under our 2023 Plan after it becomes effective will not exceed 10,912,670 shares of our common stock, which is the sum of (1) 6,500,000 new shares, plus (2) shares that remain available for the issuance of awards under our 2014 Plan as of immediately prior to the time our 2023 Plan becomes effective, plus (3) shares of our common stock subject to outstanding stock options or other stock awards (other than inducement stock options and inducement awards) that, on or after our 2023 Plan becomes effective, terminate or expire prior to exercise or settlement; are not issued because the award is settled in cash; are forfeited because of the failure to vest; or are reacquired or withheld (or not issued) to satisfy a tax withholding obligation or the purchase or exercise price, if any, as such shares become available from time to time. The maximum number of shares of our common stock that may be issued on the exercise of ISOs under our 2023 Plan will be 10,912,670 shares.

Shares subject to stock awards granted under our 2023 Plan that expire or terminate without being exercised in full or that are paid out in cash rather than in shares will not reduce the number of shares available for issuance under our 2023 Plan. Any shares of our common stock previously issued pursuant to a stock award are forfeited back to or repurchased or reacquired by us because of a failure to meet a contingency or condition required for the vesting of such shares will be added back to the share reserve and again become available under the 2023 Plan. In addition, shares withheld to satisfy a tax withholding obligation in connection with an award other than a stock option or stock appreciation right, will not reduce the number of shares available for issuance under our 2023 Plan. However, the following types of shares subject to stock awards will reduce the share reserve and will not become available for the grant of new stock awards under the 2023 Plan: (1) shares of common stock reacquired or withheld (or not issued) by us to satisfy the exercise or purchase price of a stock award, including any shares subject to a stock award that are not delivered to a participant because the stock award is exercised through a reduction of shares subject to the stock award, (2) shares reacquired or withheld (or not issued) by the company to satisfy a tax withholding obligation in connection with an option or stock appreciation right, and (3) any shares repurchased on the open market with the proceeds of the exercise or strike price of an option or stock appreciation right.

Plan Administration. Our board of directors, or a duly authorized committee of our board of directors, will administer our 2023 Plan. Our board of directors may also delegate to one or more persons or bodies the authority to do one or more of the following: (i) designate recipients (other than officers) of specified stock awards, provided that no person or body may be delegated authority to grant a stock award to themself; (ii) determine the number of shares subject to such stock award; and (iii) determine the terms of such stock awards. Under our 2023 Plan, our board of directors will have the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value and the provisions of each stock award, including the period of exercisability and the vesting schedule applicable to a stock award.

The plan administrator will have the power to modify outstanding awards under our 2023 Plan; provided, however, that 2023 Plan specifically prohibits the plan administrator from repricing any outstanding stock option or stock appreciation right by reducing the exercise price of the stock option or stock appreciation right, or from canceling any outstanding stock option or stock appreciation right that has an exercise price or strike price in excess of the current fair market value in exchange for cash or other stock awards, in either case without obtaining the approval of our stockholders within 12 months prior to such event.

Stock Options. Our 2023 Plan allows for the grant of ISOs and NSOs pursuant to stock option agreements adopted by the plan administrator. The plan administrator will determine the exercise price for stock options, within the terms and conditions of our 2023 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant for NSOs and 110% of the fair market value of the stock subject to the option on the date of grant for ISOs. Options granted under our 2023 Plan will vest at the rate specified in the stock option agreement as determined by the plan administrator. The plan administrator will determine the term of stock options granted under our 2023 Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement, or other written agreement between us and the recipient approved by the plan administrator, provide otherwise, if an optionholder’s service relationship with us or any of our affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that either an exercise of the option or an immediate sale of shares acquired upon exercise of the option following such a termination of service is prohibited by applicable securities laws or our insider trading policy. If an optionholder’s service relationship

with us or any of our affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO or (5) other legal consideration approved by the plan administrator.

Unless the plan administrator provides otherwise, options or stock appreciation rights generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the plan administrator or a duly authorized officer, an option may be transferred pursuant to a domestic relations order, official marital settlement agreement or other divorce or separation instrument.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of our common stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our parent or subsidiary corporations unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Unit Awards. Our 2023 Plan allows for the grant of RSU awards pursuant to restricted stock unit award agreements adopted by the plan administrator. RSU awards may be granted in consideration for any form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. An RSU award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator or in any other form of consideration set forth in the RSU award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by an RSU award. Except as otherwise provided in the applicable award agreement or other written agreement between us and the recipient approved by the plan administrator, RSU awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards. Our 2023 Plan allows for the grant of restricted stock awards pursuant to restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, past or future services to us or any other form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. The plan administrator will determine the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with us ends for any reason, we may receive any or all of the shares of common stock held by the participant that have not vested as of the date the participant terminates service with us through a forfeiture condition or a repurchase right.

Stock Appreciation Rights. Our 2023 Plan allows for the grant of stock appreciation rights pursuant to stock appreciation right agreements adopted by the plan administrator. The plan administrator will determine the purchase price or strike price for a stock appreciation right, which generally will not be less than 100% of the fair market value of our common stock on the date of grant. A stock appreciation right granted under our 2023 Plan will vest at the rate specified in the stock appreciation right agreement as determined by the plan administrator. Stock appreciation rights may be settled in cash or shares of common stock or in any other form of payment as determined by our board of directors and specified in the stock appreciation right agreement.

The plan administrator will determine the term of stock appreciation rights granted under our 2023 Plan, up to a maximum of 10 years. If a participant’s service relationship with us or any of our affiliates ceases for any reason other than cause, disability or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by

applicable securities laws. If a participant’s service relationship with us, or any of our affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. Our 2023 Plan will permit the grant of performance awards that may be settled in stock, cash, or other property. Performance awards may be structured so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period. Performance awards that are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, the common stock.

The performance criteria that will be used to establish such performance goals may be based on any one of, or combination of, the following as determined by the plan administrator: earnings (including earnings per share and net earnings); earnings before interest, taxes and depreciation; earnings before interest, taxes, depreciation and amortization; total stockholder return; return on equity or average stockholder’s equity; return on assets, investment, or capital employed; stock price; margin (including gross margin); income (before or after taxes); operating income; operating income after taxes; pre-tax profit; operating cash flow; sales or revenue targets; increases in revenue or product revenue; expenses and cost reduction goals; improvement in or attainment of working capital levels; economic value added (or an equivalent metric); market share; cash flow; cash flow per share; share price performance; debt reduction; customer satisfaction; stockholders’ equity; capital expenditures; debt levels; operating profit or net operating profit; workforce diversity; growth of net income or operating income; billings; preclinical development related compound goals; financing; regulatory milestones, including approval of a compound; stockholder liquidity; corporate governance and compliance; product commercialization; intellectual property; personnel matters; progress of internal research or clinical programs; progress of partnered programs; partner satisfaction; budget management; clinical achievements; completing phases of a clinical trial (including the treatment phase); announcing or presenting preliminary or final data from clinical trials, in each case, whether on particular timelines or generally; timely completion of clinical trials; submission of INDs and BLAs and other regulatory achievements; partner or collaborator achievements; internal controls, including those related to the Sarbanes-Oxley Act of 2002; research progress, including the development of programs; investor relations, analysts and communication; manufacturing achievements

(including obtaining particular yields from manufacturing runs and other measurable objectives related to process development activities); strategic partnerships or transactions (including in-licensing and out-licensing of intellectual property); establishing relationships with commercial entities with respect to the marketing, distribution and sale of the company’s product candidates (including with group purchasing organizations, distributors and other vendors); supply chain achievements (including establishing relationships with manufacturers or suppliers of active pharmaceutical ingredients and other component materials and manufacturers of the company’s product candidates); co-development, co-marketing, profit sharing, joint venture or other similar arrangements; individual performance goals; corporate development and planning goals; and other measures of performance selected by the plan administrator.

The performance goals may be based on a company-wide basis, with respect to one or more business units, divisions, affiliates, or business segments, and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise (i) in the award agreement at the time the award is granted or (ii) in such other document setting forth the performance goals at the time the goals are established, we will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to generally accepted accounting principles; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under generally accepted accounting principles; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any business divested by us achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of our common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions

to common stockholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under our bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under generally accepted accounting principles; (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under generally accepted accounting principles; and (12) to exclude the effects of the timing of acceptance for review and/or approval of submissions to the FDA, EMA or other comparable regulatory authority. In addition, we retain the discretion to reduce or eliminate the compensation or economic benefit due upon attainment of the goals. The performance goals may differ from participant to participant and from award to award.

Other Stock Awards. The plan administrator will be permitted to grant other awards based in whole or in part by reference to our common stock. The plan administrator will set the number of shares under the stock award (or cash equivalent) and all other terms and conditions of such awards.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure, such as a stock split, reverse stock split or recapitalization, appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under our 2023 Plan, (2) the class and maximum number of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued on the exercise of ISOs and (4) the class and number of shares and exercise price, strike price or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions. In the event of a corporate transaction, unless otherwise provided in a participant’s stock award agreement or other written agreement with us or one of our affiliates or unless otherwise expressly provided by the plan administrator at the time of grant, any stock awards outstanding under our 2023 Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by us with respect to the stock award may be assigned to the successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such stock awards, then (1) with respect to any such stock awards that are held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such stock awards will be accelerated in full to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such stock awards will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by us with respect to such stock awards will lapse (contingent upon the effectiveness of the corporate transaction) and (2) any such stock awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by us with respect to such stock awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event a stock award will terminate if not exercised prior to the effective time of a corporate transaction, the plan administrator may provide, in its sole discretion, that the holder of such stock award may not exercise such stock award but instead will receive a payment equal in value to the excess (if any) of (1) the per share amount payable to holders of common stock in connection with the corporate transaction, over (2) any per share exercise price payable by such holder, if applicable. In addition, any escrow, holdback, earn out or similar provisions in the definitive agreement for the corporate transaction may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of common stock.

Under our 2023 Plan, a corporate transaction is generally defined as the consummation of: (1) a sale of all or substantially all of our assets, (2) the sale or disposition of at least 50% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction or (4) a merger or consolidation where we do survive the transaction but the shares of our common stock outstanding immediately before such transaction are converted or exchanged into other property by virtue of the transaction.

Change in Control. Awards granted under our 2023 Plan may be subject to acceleration of vesting and exercisability upon or after a change in control as may be provided in the applicable stock award agreement or in any other written agreement between us or any affiliate and the participant, but in the absence of such provision, no such acceleration will automatically occur.

Under our 2023 Plan, a change in control is generally defined as: (1) the acquisition by any person or company of more than 50% of the combined voting power of our then outstanding stock; (2) a consummated

merger, consolidation or similar transaction in which our stockholders immediately before the transaction do not own, directly or indirectly, more than 50% of the combined voting power of the surviving entity (or the parent of the surviving entity) in substantially the same proportions as their ownership immediately prior to such transaction; (3) a consummated sale, lease, exclusive license or other disposition of all or substantially all of our assets other than to an entity more than 50% of the combined voting power of which is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction; or (4) when a majority of our board of directors becomes comprised of individuals who were not serving on our board of directors on the date our 2023 Plan was adopted by the board of directors, or the incumbent board, or whose nomination, appointment, or election was not approved by a majority of the incumbent board still in office.

Plan Amendment or Termination. Our board of directors has the authority to amend, suspend or terminate our 2023 Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require the approval of our stockholders. No ISOs may be granted after the tenth anniversary of the date our board of directors adopts our 2023 Plan. No stock awards may be granted under our 2023 Plan while it is suspended or after it is terminated.

The following is a summary of the principal United States federal income tax consequences to participants and us with respect to participation in the 2023 Plan. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information set forth below is a summary only and does not purport to be complete. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any recipient may depend on his or her particular situation, each recipient should consult the recipient’s tax adviser regarding the federal, state, local and other tax consequences of the grant or exercise of an award or the disposition of stock acquired as a result of an award under the 2023 Plan. The 2023 Plan is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974. Our ability to realize the benefit of any tax deductions described below depends on our generation of taxable income, as well as the requirement of reasonableness, the provisions and limitations of Section 162(m) of the Code and the satisfaction of our tax reporting obligations.

The exemption from Section 162(m)’s deduction limit for performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our covered executive officers in excess of $1 million will not be deductible unless it qualifies for transition relief applicable to certain performance-based compensation arrangements already in place as of November 2, 2017.

Nonstatutory Stock Options. Generally, there is no taxation upon the grant of a nonstatutory stock option if the option is granted with an exercise price equal to the fair market value of the underlying stock on the grant date. On exercise, an optionholder will recognize ordinary income equal to the excess, if any, of the fair market value on the date of exercise of the stock over the exercise price. If the optionholder is employed by us or one of our affiliates, that income will be subject to withholding tax. The optionholder’s tax basis in those shares will be equal to their fair market value on the date of exercise of the option, and the optionholder’s capital gain holding period for those shares will begin on that date. Subject to the requirement of reasonableness, the provisions and limitations of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the optionholder.

Incentive Stock Options. The 2023 Plan provides for the grant of stock options that are intended to qualify as “incentive stock options,” as defined in Section 422 of the Code. Under the Code, an optionholder generally is not subject to ordinary income tax upon the grant or exercise of an ISO. If the optionholder holds a share received on exercise of an ISO for more than two years from the date the option was granted and more than one year from the date the option was exercised, which is referred to as the required holding period, the difference, if any, between the amount realized on a sale or other taxable disposition of that share and the holder’s tax basis in that share will be a long-term capital gain or loss.

If, however, an optionholder disposes of a share acquired on exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the optionholder generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date the ISO was exercised over the exercise price. However, if the sales

proceeds are less than the fair market value of the share on the date of exercise of the stock option, the amount of ordinary income recognized by the optionholder will not exceed the gain, if any, realized on the sale. If the amount realized on a disqualifying disposition exceeds the fair market value of the share on the date of exercise of the stock option, that excess will be a short-term or long-term capital gain, depending on whether the holding period for the share exceeds one year.

For purposes of the alternative minimum tax, the amount by which the fair market value of a share of stock acquired on exercise of an ISO exceeds the exercise price of the stock option generally will be an adjustment included in the optionholder’s alternative minimum taxable income for the year in which the option is exercised. If, however, there is a disqualifying disposition of the share in the year in which the stock option is exercised, there will be no adjustment for alternative minimum tax purposes with respect to that share. In computing alternative minimum taxable income, the tax basis of a share acquired on exercise of an ISO is increased by the amount of the adjustment taken into account with respect to that share for alternative minimum tax purposes in the year the option is exercised.

We are not allowed an income tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired on exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, we are allowed a deduction in an amount equal to the ordinary income includible in income by the optionholder, subject to the requirement of reasonableness and the provisions and limitations of Section 162(m) of the Code, and provided that either the employee includes that amount in income or we timely satisfy our reporting requirements with respect to that amount.

Restricted Stock Awards. Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is not vested when it is received (for example, if the employee is required to work for a period of time in order to have the right to sell the stock), the recipient generally will not recognize income until the stock becomes vested, at which time the recipient will recognize ordinary income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the recipient in exchange for the stock. A recipient may, however, file an election with the Internal Revenue Service, within 30 days after his or her receipt of the stock award, to recognize ordinary income, as of the date the recipient receives the award, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the recipient in exchange for the stock. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from stock awards will be the amount paid for such shares plus any ordinary income recognized either when the stock is received or when the stock becomes vested. Subject to the requirement of reasonableness, the provisions and limitations of Section 162(m) and the satisfaction of a tax reporting obligation, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock award.

Stock Appreciation Rights. Generally, if a stock appreciation right is granted with an exercise price equal to the fair market value of the underlying stock on the date of grant, the recipient will recognize ordinary income equal to the fair market value of stock or cash received upon such exercise. If the recipient is employed by us or one of our affiliates, that income will be subject to withholding taxes. Subject to the requirement of reasonableness, the provisions and limitations of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to an income tax deduction equal to the amount of ordinary income realized by the recipient of the stock appreciation right.

Restricted Stock Units. Generally, the recipient of a restricted stock unit award structured to conform to the requirements of Section 409A of the Code or an exception to Section 409A of the Code will recognize ordinary income at the time the shares are delivered to the participant in an amount equal to the excess, if any, of the fair market value of the shares received over any amount paid by the recipient in exchange for the shares. If a restricted stock unit award is subject to Section 409A of the Code, the shares subject to a restricted stock unit award may generally only be delivered upon one of the following events: a fixed calendar date (or dates), separation from service, death, disability, or a change in control. If delivery occurs on another date, unless the restricted stock unit awards otherwise comply with or qualify for an exception to the requirements of Section 409A of the Code, in addition to the tax treatment described above, the recipient will owe an additional 20% federal tax and interest on any taxes owed. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock unit award will be the amount paid, if any,

for shares plus any ordinary income recognized when the stock is delivered. Subject to the requirement of reasonableness, the provisions and limitations of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to an income tax deduction equal to the amount of ordinary income realized by the participant.

Awards under the 2023 Plan are discretionary. Accordingly, total awards that may be granted under the 2023 Plan are not determinable. We have made certain grants to our employees and to certain executive officers, as discussed below under “Executive Compensation” and we may make additional grants to certain of our executive officers later this year as well as to our non-employee directors under our Director Compensation Policy described below under “Non-Employee Director Compensation.” However, we cannot currently determine the total amount of benefits or number of shares subject to equity awards that may be granted in the future to executive officers, directors and employees under the 2023 Plan.

The affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve the 2023 Plan. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

The Board is requesting stockholder approval of the amendment and restatement of the SCYNEXIS, Inc. 2014 Employee Stock Purchase Plan (the “2014 ESPP”). We refer to such 2014 ESPP as so amended in this proxy statement as the “Amended 2014 ESPP”.

The Amended 2014 ESPP contains the following material change from the 2014 ESPP:

Approval of the Amended 2014 ESPP will allow us to continue to provide our employees with the opportunity to acquire an ownership interest in the company through their participation in the Amended 2014 ESPP, thereby encouraging them to remain in our service and more closely aligning their interests with those of our stockholders.

If this Proposal 6 is approved by our stockholders, an additional 1,500,000 shares of our common stock will be available for issuance under the Amended 2014 ESPP. As of March 31, 2023, a total of 279 shares of our common stock remained available for issuance under the 2014 ESPP. We do not maintain any other employee stock purchase plans. As of March 31, 2023, a total of 33,327,627 shares of our common stock were outstanding (excluding pre-funded warrants).

A summary of the principal features of the Amended 2014 ESPP follows below. The summary is qualified by the full text of the Amended 2014 ESPP which is attached as Appendix B of the proxy statement filed with the SEC.

The purpose of the Amended 2014 ESPP is to provide a means by which our employees may be given an opportunity to purchase shares of our common stock, to assist us in retaining the services of our employees, to secure and retain the services of new employees and to provide incentives for such persons to exert maximum efforts for our success. The rights to purchase common stock granted under the Amended 2014 ESPP are intended to qualify as options issued under an “employee stock purchase plan” as that term is defined in Section 423(b) of the Internal Revenue Code of 1986, as amended (the “Code”).

The Board has the power to administer the Amended 2014 ESPP and may also delegate administration of the Amended 2014 ESPP to a committee comprised of one or more members of the Board. The Board has delegated administration of the Amended 2014 ESPP to the Compensation Committee, but may, at any time, revest in itself some or all of the powers previously delegated to the Compensation Committee. Each of the Board and the Compensation Committee is considered to be a Plan Administrator for purposes of this Proposal 6. The Plan Administrator has the power to construe and interpret both the Amended 2014 ESPP and the rights granted under it. The Plan Administrator has the power, subject to the provisions of the Amended 2014 ESPP, to determine when and how rights to purchase our common stock will be granted, the provisions of each offering of such rights (which need not be identical), and whether employees of any of our parent or subsidiary companies will be eligible to participate in the Amended 2014 ESPP.

Subject to adjustment for certain changes in our capitalization, the maximum number of shares of our common stock that may be issued under the Amended 2014 ESPP is 1,531,248 shares, which is equal to the sum of (i) 4,779 shares that were originally approved by stockholders in February 2014, (ii) 26,469 shares added between 2015 and 2023 pursuant to the annual increase provision of the 2014 ESPP, and (iii) an additional 1,500,000 shares that are subject to approval by our stockholders under this Proposal 6 . If any rights granted under the Amended 2014 ESPP terminate without being exercised in full, the shares of common stock not purchased under such rights again become available for issuance under the Amended 2014 ESPP. The shares of common stock purchasable under the Amended 2014 ESPP will be shares of authorized but unissued or reacquired common stock, including shares repurchased by us on the open market.

The Amended 2014 ESPP will be implemented by offerings of rights to purchase our common stock to all eligible employees. The Plan Administrator will determine the duration of each offering period, provided that in no event may an offering period exceed 27 months. The Plan Administrator may establish separate offerings which vary in terms (although not inconsistent with the provisions of the Amended 2014 ESPP or the requirements of applicable laws). Each offering period will have one or more purchase dates, as determined by the Plan Administrator prior to the commencement of the offering period. The Plan Administrator has the authority to alter the terms of an offering prior to the commencement of the offering period, including the duration of subsequent offering periods. When an eligible employee elects to join an offering period, he or she is granted a right to purchase shares of our common stock on each purchase date within the offering period. On the purchase date, all contributions collected from the participant are automatically applied to the purchase of our common stock, subject to certain limitations (which are described further below under “Eligibility”).

The Plan Administrator has the discretion to structure an offering so that if the fair market value of our common stock on the first trading day of a new purchase period within the offering period is less than or equal to the fair market value of our common stock on the first day of the offering period, then that offering will terminate immediately as of that first trading day, and the participants in such terminated offering will be automatically enrolled in a new offering beginning on the first trading day of such new purchase period.

Any individual who is employed by us (or by any of our parent or subsidiary companies if such company is designated by the Plan Administrator as eligible to participate in the Amended 2014 ESPP) may participate in offerings under the Amended 2014 ESPP, provided such individual has been employed by us (or our parent or subsidiary, if applicable) for such continuous period preceding the first day of the offering period as the Plan Administrator may require, but in no event may the required period of continuous employment be equal to or greater than two years. In addition, the Plan Administrator may provide that an employee will not be eligible to be granted purchase rights under the Amended 2014 ESPP unless such employee is customarily employed for more than 20 hours per week and more than five months per calendar year. The Plan Administrator may also provide in any offering that certain of our employees who are “highly compensated” as defined in the Code are not eligible to participate in the Amended 2014 ESPP.

No employee will be eligible to participate in the Amended 2014 ESPP if, immediately after the grant of purchase rights, the employee would own, directly or indirectly, stock possessing 5% or more of the total combined voting power or value of all classes of our stock or of any of our parent or subsidiary companies, including any stock which such employee may purchase under all outstanding purchase rights and options. In addition, no employee may purchase more than $25,000 worth of our common stock (determined based on the fair market value of the shares at the time such rights are granted) under all our employee stock purchase plans and any employee stock purchase plans of our parent or subsidiary companies for each calendar year during which such rights are outstanding.

As of March 31, 2023, we had approximately 36 employees.

An eligible employee may enroll in the Amended 2014 ESPP by delivering to us, within the time specified in the offering, an enrollment form authorizing contributions as specified by the Plan Administrator, which may be up to 15% of such employee’s earnings during the offering period. Each participant will be granted a separate purchase right for each offering in which he or she participates. Unless an employee’s participation is discontinued, his or her purchase right will be exercised automatically at the end of each purchase period at the applicable purchase price.

The purchase price per share at which shares of our common stock are acquired pursuant to purchase rights on each purchase date during an offering period will not be less than the lower of (i) 85% of the fair market value of a share of our common stock on the first day of the offering period or (ii) 85% of the fair market value of a share of our common stock on the applicable purchase date.

As of March 31, 2023, the closing price of our common stock as reported on the Nasdaq Global Market was $3.00 per share.

The purchase of shares during an offering period generally will be funded by a participant’s payroll deductions accumulated during the offering period. A participant may change his or her rate of contributions, if and as permitted in the offering. All contributions made for a participant are credited to his or her account under the Amended 2014 ESPP and deposited with our general funds.

In connection with each offering made under the Amended 2014 ESPP, the Plan Administrator may specify (i) a maximum number of shares of our common stock that may be purchased by any participant on any such purchase date during such offering, (ii) a maximum aggregate number of shares of our common stock that may be purchased by all participants pursuant to such offering, and/or (iii) a maximum aggregate number of shares of our common stock that may be purchased by all participants on any purchase date under the offering. If the aggregate purchase of shares of our common stock issuable upon exercise of purchase rights granted under such offering would exceed any such maximum aggregate number, then, in the absence of any action by the Plan Administrator otherwise, a pro rata allocation of available shares of our common stock will be made in as nearly a uniform manner as will be practicable and equitable.

Participants may withdraw from a given offering by delivering a withdrawal form to us and terminating their contributions. Such withdrawal may be elected at any time prior to the end of an offering, except as otherwise provided by the Plan Administrator. Upon such withdrawal, we will distribute to the employee his or her accumulated but unused contributions without interest, and such employee’s right to participate in that offering will terminate. However, an employee’s withdrawal from an offering does not affect such employee’s eligibility to participate in subsequent offerings under the Amended 2014 ESPP.

Except as required by law, a participant’s outstanding purchase rights under any offering under the Amended 2014 ESPP will terminate immediately upon either (i) termination of the participant’s employment with us (or any of our parent or subsidiary companies if such company is designated by the Plan Administrator as eligible to participate in the Amended 2014 ESPP) or (ii) any other circumstance or event that causes the participant to no longer be eligible to participate in the offering. In such event, we will distribute to the participant his or her accumulated but unused contributions.

Rights granted under the Amended 2014 ESPP are not transferable except by will, the laws of descent and distribution, or, if permitted by us, by a beneficiary designation. During the lifetime of the participant, such rights may only be exercised by the participant.

In the event of certain changes in our capitalization, the Plan Administrator will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Amended 2014 ESPP; (ii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding offerings and purchase rights; and (iii) the class(es) and number of securities that are the subject of the purchase limits under each ongoing offering.

In the event of a corporate transaction (as defined in the Amended 2014 ESPP and described below), any surviving or acquiring corporation (or its parent) may assume or continue outstanding purchase rights under the Amended 2014 ESPP or may substitute similar rights. If any surviving or acquiring corporation (or its parent) does not assume or continue such rights or substitute similar rights, then the participants’ accumulated payroll deductions will be used to purchase shares of common stock prior to the corporate transaction under the ongoing offering and the participants’ rights under the ongoing offering will terminate immediately after such purchase.

The Plan Administrator may amend, suspend or terminate the Amended 2014 ESPP at any time. However, except in regard to certain capitalization adjustments, any amendment must be approved by our stockholders if such approval is required by applicable law or listing requirements.

Any outstanding purchase rights granted before an amendment, suspension or termination of the Amended 2014 ESPP will not be materially impaired by any such amendment, suspension or termination, except (i) with

the consent of the employee to whom such purchase rights were granted, (ii) as necessary to comply with any laws, listing requirements or governmental regulations (including Section 423 of the Code), or (iii) as necessary to obtain or maintain favorable tax, listing or regulatory treatment.

The following is a summary of the principal United States federal income taxation consequences to participants and us with respect to participation in the Amended 2014 ESPP. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, and other tax consequences of the grant or exercise of an option or the disposition of common stock acquired under the Amended 2014 ESPP. The Amended 2014 ESPP is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Rights granted under the Amended 2014 ESPP are intended to qualify for favorable federal income tax treatment associated with rights granted under an employee stock purchase plan which qualifies under the provisions of Section 423 of the Code.

A participant will be taxed on amounts withheld for the purchase of shares of our common stock as if such amounts were actually received. Otherwise, no income will be taxable to a participant as a result of the granting or exercise of a purchase right until a sale or other disposition of the acquired shares. The taxation upon such sale or other disposition will depend upon the holding period of the acquired shares.

If the shares are sold or otherwise disposed of more than two years after the beginning of the offering period and more than one year after the shares are transferred to the participant, then the lesser of the following will be treated as ordinary income: (i) the excess of the fair market value of the shares at the time of such sale or other disposition over the purchase price; or (ii) the excess of the fair market value of the shares as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period). Any further gain or any loss will be taxed as a long-term capital gain or loss.

If the shares are sold or otherwise disposed of before the expiration of either of the holding periods described above, then the excess of the fair market value of the shares on the purchase date over the purchase price will be treated as ordinary income at the time of such sale or other disposition. The balance of any gain will be treated as capital gain. Even if the shares are later sold or otherwise disposed of for less than their fair market value on the purchase date, the same amount of ordinary income is attributed to the participant, and a capital loss is recognized equal to the difference between the sales price and the fair market value of the shares on such purchase date. Any capital gain or loss will be short-term or long-term, depending on how long the shares have been held.

There are no federal income tax consequences to us by reason of the grant or exercise of rights under the Amended 2014 ESPP. We are entitled to a deduction to the extent amounts are taxed as ordinary income to a participant for shares sold or otherwise disposed of before the expiration of the holding periods described above (subject to the requirement of reasonableness and the satisfaction of tax reporting obligations).

The following table sets forth, for each of the individuals and various groups indicated, the total number of shares of our common stock that have been purchased under the 2014 ESPP as of March 31, 2023.

Participation in the Amended 2014 ESPP is voluntary and each eligible employee will make his or her own decision regarding whether and to what extent to participate in the Amended 2014 ESPP. In addition, we have not approved any grants of purchase rights that are conditioned on stockholder approval of this Proposal 6. Accordingly, we cannot determine the benefits or amounts that will be received in the future by individual employees or groups of employees under the Amended 2014 ESPP. Our non-employee directors will not be eligible to participate in the Amended 2014 ESPP.

The affirmative vote of the holders of a majority of shares present (either in person or by proxy) and entitled to vote on the matter at the Annual Meeting will be required to approve this Proposal 6. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum but are not counted for any purpose in determining whether this Proposal 6 has been approved.

The following table provides information with respect to all of our equity compensation plans in effect as of December 31, 2022.

The following table provides information regarding the compensation of our principal executive officer and our two other highest paid executive officers as of December 31, 2022, and our former chief commercial officer during 2022, for each of the years ended December 31, 2022 and 2021. We refer to these executive officers and our former executive officer as our named executive officers.

Our executive officers receive annual salaries, may receive annual cash performance bonuses based on a percentage of their respective annual salaries upon achievement of weighted performance goals as established by our board of directors or Compensation Committee, and equity incentive grants. Our Compensation Committee determines annual salaries, sets annual cash performance bonus targets, and determines annual cash performance bonuses to be paid, in each case based on individual and corporate performance, market data, and other information following discussion and consultation with Radford and Pearl Meyer, the Compensation Committee’s independent compensation consultants through May 2022 and since June 2022, respectively. In February 2022, as part of its annual performance compensation review, the Compensation Committee awarded: (a) the following restricted stock units to our named executive officers to acquire the following numbers of shares: Dr. Angulo, 51,100 shares, Mr. Sukenick, 40,700 shares, Dr. Taglietti, 87,200 shares, and Ms. Coyne, 43,200 shares; and (b) the following option awards to our named executive officers to purchase the following numbers of shares: Dr. Angulo, 85,000 shares, Mr. Sukenick, 70,000 shares, Dr. Taglietti, 232,000 shares, and Ms. Coyne, 75,000 shares. The stock options allow these named executive officers to purchase shares of our common stock at a price equal to $4.60, the fair market value of our common stock on February 4, 2022, the date of grant. The shares subject to the restricted stock units vest 50% per year over two years on the anniversary of the date of grant, and the stock options vest in equal monthly installments for 48 months as measured from the date of grant, subject to the continued employment of the named executive officer through the respective vesting date.

The Compensation Committee determined these amounts based on individual and corporate performance, market data, and other information following discussion and consultation with Radford, the Compensation Committee’s independent compensation consultant at the time.

The following table provides information regarding outstanding equity awards held by our named executive officers as of December 31, 2022.

We have entered into an employment agreement with each of our named executive officers. These agreements generally provide for “at will” employment and set forth the terms and conditions of employment of each named executive officer. Each of the executive officers entered into a confidentiality, invention and non-competition agreement with us, which is incorporated by reference in his employment agreement.

Employment agreement with Dr. Angulo. We entered into an employment agreement with Dr. Angulo in January 2023 setting forth the terms of Dr. Angulo’s employment as our Chief Executive Officer. Pursuant to the agreement, Dr. Angulo was entitled to receive an annual salary of $565,000 and is eligible to receive an annual performance bonus of up to 55% of his base salary and certain equity awards. Dr. Angulo is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Employment agreement with Mr. Sukenick. We entered into an employment agreement with Mr. Sukenick in November 2017 setting forth the terms of Mr. Sukenick’s employment as our General Counsel. Pursuant to the agreement, Mr. Sukenick was entitled to receive an annual salary of $320,000 (which was subsequently increased to $333,000 for 2019, $350,000 for 2020, $371,700 for 2021, $400,000 for 2022, and $428,000 for 2023) and is eligible to receive an annual performance bonus of up to 40% of his base salary and certain equity awards. Mr. Sukenick is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Employment agreement with Dr. Taglietti. We entered into an employment agreement with Dr. Taglietti in February 2015 setting forth the terms of Dr. Taglietti’s employment as our Chief Executive Officer. Pursuant to the agreement, Dr. Taglietti was entitled to receive an annual salary of $480,000 (which was subsequently increased to $510,000 for 2017, $530,000 for 2018, $545,000 for 2019, $561,350 for 2020, 579,320 for 2021, and $602,500 for 2022) and is eligible to receive an annual performance bonus of up to 50% of his base salary (or such higher amount as determined by the Compensation Committee) and certain equity awards. Dr. Taglietti is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below. In April 2016, we and Dr. Taglietti amended the severance provisions of the employment agreement to avoid adverse tax consequences in the event that severance was to be paid. In connection with Dr. Taglietti’s retirement, on October 20, 2022, we entered into a separation agreement with Dr. Taglietti pursuant to which Dr. Taglietti will receive separation benefits consistent with the payment and severance benefits set forth his employment agreement and, in addition, the post-termination exercise period of his stock options to purchase shares of our common stock has been extended from 90 days to four years.

Dr. Angulo and Mr. Sukenick are entitled to certain severance payments and benefits under their respective employment agreements, subject to the applicable executive officer executing a release and settlement agreement in a form acceptable to us.

In the event of a termination without “just cause” by us or an executive officer’s resignation for “good reason” at any time other than during the twelve-month period following a “change in control,” the executive officer is eligible to receive the following payments and benefits:

In the event of a termination without “just cause” by us or an executive officer’s resignation for “good reason” at any time during the period that is within twelve months following a “change in control,” the executive officer is eligible to receive the following payments and benefits:

Each executive officer’s employment agreement contains a “better after-tax” provision, which provides that if any of the payments to the executive officer constitutes a parachute payment under Section 280G of the Internal Revenue Code, the payments will either be (i) reduced or (ii) provided in full to the executive, whichever results in the executive receiving the greater amount after taking into consideration the payment of all taxes, including the excise tax under Section 4999 of the Internal Revenue Code, in each case based upon the highest marginal rate for the applicable tax.

For purposes of the agreements described above:

In addition to the amounts presented above, each executive officer is eligible to receive any benefits accrued under our broad-based benefit plans, such as accrued vacation pay, in accordance with those plans and policies. In the event that we determine that an executive officer has earned all or a portion of his annual performance bonus, we will pay the executive officer such earned amount within 30 days of the date of our determination.

On October 20, 2022, we entered into a separation agreement with Dr. Taglietti pursuant to which Dr. Taglietti ceased to be an employee of the company on December 31, 2022. The separation agreement provides we will pay Dr. Taglietti, as severance, 12 months continued base salary, as in effect on October 20, 2022, eligibility for annual bonus payments pursuant to the terms of his employment agreement, and up to 12 months of COBRA coverage. Further, pursuant to the separation agreement, his time-based unvested options and restricted stock units were accelerated to vest until December 31, 2023, and the post-termination exercise period for his options was extended. In connection with the execution of the separation agreement, Mr. Taglietti signed a general release in favor of us on October 20, 2022 and resigned from the Board, effective December 31, 2022.

On November 30, 2022, we entered into a separation agreement with Ms. Coyne pursuant to which Ms. Coyne ceased to be an employee and Chief Commercial Officer of the company as of November 30, 2022. Pursuant to the terms of her employment agreement, we will pay Ms. Coyne, as severance, six months continued base salary, as in effect on November 30, 2022, up to six months of COBRA coverage and 12 months of outplacement services. Further, pursuant to the separation agreement, all her time-based unvested options and restricted stock awards were accelerated to vest until May 31, 2023.

The following table reports the compensation of our principal executive officer (“PEO”) and the average compensation of the other named executive officers (“Other NEOs”) as reported in the Summary Compensation Table for the past two fiscal years, as well as their “compensation actually paid” as calculated pursuant to recently adopted SEC rules and certain performance measures required by the rules, including total stockholder return (“TSR”).

As described in above, our executive compensation program reflects a variable pay-for-performance philosophy. The metrics that we use for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. However, these performance measures are predominantly related to ensuring sufficient cash runway and ongoing clinical development, and the only financial performance measure used by us to link executive compensation actually paid to our NEOs in 2021 and 2022 was net sales.

As described in more detail above, our executive compensation program reflects a variable pay-for-performance philosophy. While we utilize several performance measures to align executive compensation with our performance, all of those company measures are not presented in the Pay versus Performance table. Moreover, we generally seek to incentivize long-term performance, and our performance measures are not specifically aligned with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following presentations of the relationships between information presented in the Pay versus Performance table.

All information provided above under the “Pay Versus Performance” heading will not be deemed to be incorporated by reference into any filing of SCYNEXIS under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent we specifically incorporate such information by reference.

The following table sets forth information regarding compensation earned by our non-employee directors during the fiscal year ended December 31, 2022.

Information regarding Dr. Angulo, our Chief Executive Officer, is set forth under “Executive Compensation” above.

The following table sets forth information regarding the number of shares of our common stock subject to outstanding restricted stock units and stock options held by our non-employee directors as of December 31, 2022.

Our non-employee directors are compensated in accordance with the following policy:

Each non-employee director receives an annual base cash retainer of $40,000 for such service, to be paid quarterly. In addition, the chairman of the Board receives an additional annual base cash retainer of $35,000, to be paid quarterly.

In addition, each member of a committee receives compensation for service on a committee as follows:

The Board has established our non-employee director compensation policy with respect to equity grants to provide that each year on the first business day following the company’s annual meeting of stockholders, each non-employee director will automatically be granted a restricted stock unit to acquire 10,000 shares of the company’s common stock and an option to purchase 10,000 shares of the company’s common stock at an exercise price per share equal to the fair market value of a share of common stock on the date of grant. These annual grants will vest in full on the one-year anniversary of the grant date, provided that the non-employee director is providing continuous services on the applicable vesting date. If a new board member joins the Board, the director will be granted an initial restricted stock unit to acquire 20,000 shares of the company’s common stock and an initial option to purchase 20,000 shares of the company’s common stock at an exercise price per share equal to the fair market value of a share of common stock on the date of grant. These initial grants will vest over three years following the date of grant. One-third of the restricted stock units will vest each year on the anniversary of the date of grant. One-third of the options will vest on the first anniversary of the date of grant and the balance will vest in equal monthly installments over the remaining two-year period.

In addition, each non-employee director may elect to receive nonstatutory stock options in lieu of all or a portion of the cash compensation to which the non-employee director would otherwise be entitled to, as described above. Each non-employee director shall make their election prior to the period in which the compensation is to be earned. For each non-employee director electing to receive a nonstatutory stock option in lieu of such cash compensation, the date on which the nonstatutory stock options will be granted will be the date on which the cash compensation would otherwise have been earned, which is generally the first business day of each fiscal quarterly period, and the number of shares underlying such stock option will be determined by (i) dividing the cash compensation that the non-employee director elects to forgo in exchange for such nonstatutory stock options by 0.65, and (ii) dividing the result by the fair market value of a share of common stock on the date of grant. Each nonstatutory stock option granted in lieu of cash compensation pursuant to a non-employee director’s election will be 100% vested on the date of grant. After a non-employee director has elected to receive nonstatutory stock options in lieu of cash compensation, the option grants made to that non-employee director are awarded automatically pursuant to the previously described policy and no further action is required by the Board.

In February 2014, our board of directors adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the prior consent of our Audit Committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons in which the amount involved exceeds $120,000 and such person would have a direct or indirect interest must first be presented to our Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, our Audit Committee is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

Other than compensation arrangements for our directors and named executive officers previously described, since January 1, 2021, the following are the only transactions with our directors and named executive officers to which we were a party or will be a party, in which:

On April 22, 2022, we completed a public offering of our common stock and warrants pursuant to our effective shelf registration for gross proceeds of approximately $45.0 million. We sold an aggregate of (a) 3,333,333 shares of our common stock, par value $0.001 per share, (b) pre-funded warrants, in lieu of common stock, to purchase 11,666,667 shares of our common stock, par value $0.001 per share, and (c) warrants, which will accompany the common stock or pre-funded warrants, to purchase up to an aggregate of 15,000,000 shares of our common stock. The pre-funded warrants entitle the holders to purchase up to 11,666,667 shares of common stock and have an unlimited term and an exercise price of $0.001 per share. The warrants entitle the holders to purchase up to an aggregate of 15,000,000 shares of common stock and have a seven-year term and an exercise price of $3.45 per share. The warrants that accompany the pre-funded warrants have an additional provision entitling the holder thereof to purchase a pre-funded warrant rather than a share of common stock at the warrant exercise price less the exercise price of the pre-funded warrant purchased. Each warrant is exercisable immediately upon issuance, subject to certain limitations on beneficial ownership. The price to the public in the offering was $3.00 per share of common stock and accompanying warrants, or in the case of pre-funded warrants, $2.999 per pre-funded warrant and accompanying warrants. The following directors, executive officers, and holders of 5% of our common stock purchased shares of our common stock and warrants in our April 2022 public offering at the public offering price:

On December 21, 2021, the Board of Directors approved a modified exercise price of $6.25 per common share for up to 6,100,000 of the Series 1 warrants outstanding from the December 2020 public offering. With Board approval, 3,370,800 of the Series 1 warrants were exercised at the reduced price of $6.25 per common

share for gross proceeds of $21.1 million which was received by us in December 2021. Of the 3,370,800 warrants exercised by the warrant holders, 1,600,000, 470,000, and 320,000 warrants were exercised by Federated Hermes, Inc., Avidity Partners Management LP, and Caxton Corporation, respectively, for gross proceeds of $10.0 million, $2.9 million, and $2.0 million, respectively.

On November 26, 2021, the Board of Directors approved a modified exercise price of $6.50 per common share for 1,111,111 of the December 2019 public offering warrants issued to Federated Hermes, Inc. On November 30, 2021, Federated provided a notice to exercise 1,111,111 of the 2019 warrants for proceeds of $7.2 million which was received by us in December 2021.

Pursuant to a consulting agreement with Danforth Advisors (“Danforth”), we issued to Danforth in November 2021 a warrant to purchase 50,000 shares of our common stock at an exercise price of $5.50 per share and incurred $0.1 million in consulting fees in 2021 and $0.6 million in consulting fees in 2022. Larry Hoffman, our former interim Chief Financial Officer, was providing consulting services to us pursuant to the consulting agreement with Danforth. The warrant will expire five years from the date of the grant and has fully vested. The warrant was initially fair valued at $0.2 million using the Black-Scholes model on the grant date. The consulting agreement was terminated in November 2022.

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials and Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders, allows us to save money by reducing the number of documents we must print and mail and helps protect the environment as well.

Householding is available to both registered stockholders (i.e., those stockholders with certificates registered in their name) and street name holders (i.e., those stockholders who hold their shares through a brokerage).

If you are a registered stockholder and have consented to our mailing of proxy materials and other stockholder information only to one account in your household, as identified by you, we will deliver or mail a single copy of our Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, for all registered stockholders residing at the same address unless contrary instructions have been received from the affected stockholders.

(a) Successor to and Continuation of Prior Plan. The Plan is the successor to and continuation of the Prior Plan. As of the Effective Date, (i) no additional awards may be granted under the Prior Plan; (ii) the Prior Plan’s Available Reserve plus any Returning Shares will become available for issuance pursuant to Awards granted under this Plan as described in Section 2(a) below; and (iii) all outstanding awards granted under the Prior Plan will remain subject to the terms of the Prior Plan (except to the extent such outstanding awards result in Returning Shares that become available for issuance pursuant to Awards granted under this Plan). All Awards granted under this Plan will be subject to the terms of this Plan.

(b) Plan Purpose. The Company, by means of the Plan, seeks to secure and retain the services of Employees, Directors and Consultants, to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and to provide a means by which such persons may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Awards.

(c) Available Awards. The Plan provides for the grant of the following Awards: (i) Incentive Stock Options; (ii) Nonstatutory Stock Options; (iii) SARs; (iv) Restricted Stock Awards; (v) RSU Awards; (vi) Performance Awards; and (vii) Other Awards.

(d) Adoption Date; Effective Date. The Plan will come into existence on the Adoption Date, but no Award may be granted prior to the Effective Date.

(a) Share Reserve. Subject to adjustment in accordance with Section 2(c) and any adjustments as necessary to implement any Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Awards will not exceed 10,912,670 shares, which number is the sum of: (i) 6,500,000 new shares, plus (ii) the Prior Plan’s Available Reserve; plus, (iii) the number of Returning Shares, if any, as such shares become available from time to time.

(b) Aggregate Incentive Stock Option Limit. Notwithstanding anything to the contrary in Section 2(a) and subject to any adjustments as necessary to implement any Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is 10,912,670 shares.

(c) Share Reserve Operation.

(a) Eligible Award Recipients. Subject to the terms of the Plan, Employees, Directors and Consultants are eligible to receive Awards.

(b) Specific Award Limitations.

(c) Aggregate Incentive Stock Option Limit. The aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is the number of shares specified in Section 2(b).

(d) Non-Employee Director Compensation Limit. The aggregate value of all compensation granted or paid, as applicable, to any individual for service as a Non-Employee Director with respect to any calendar year, including Awards granted and cash fees paid by the Company to such Non-Employee Director, will not exceed (i) $750,000 in total value or (ii) in the event such Non-Employee Director is first appointed or elected to the Board during such fiscal year, $1,000,000 in total value, in each case calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes. For avoidance of doubt, compensation will count towards this limit for the fiscal year in which it was granted or earned, and not later when distributed, in the event it is deferred.

Each Option and SAR will have such terms and conditions as determined by the Board. Each Option will be designated in writing as an Incentive Stock Option or Nonstatutory Stock Option at the time of grant; provided, however, that if an Option is not so designated, then such Option will be a Nonstatutory Stock Option, and the shares purchased upon exercise of each type of Option will be separately accounted for. Each SAR will be denominated in shares of Common Stock equivalents. The terms and conditions of separate Options and SARs need not be identical; provided, however, that each Option Agreement and SAR Agreement will conform

(through incorporation of provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

(a) Term. Subject to Section 3(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration of ten years from the date of grant of such Award or such shorter period specified in the Award Agreement.

(b) Exercise or Strike Price. Subject to Section 3(b) regarding Ten Percent Stockholders, the exercise or strike price of each Option or SAR will not be less than 100% of the Fair Market Value on the date of grant of such Award. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than 100% of the Fair Market Value on the date of grant of such Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Sections 409A and, if applicable, 424(a) of the Code.

(c) Exercise Procedure and Payment of Exercise Price for Options. In order to exercise an Option, the Participant must provide notice of exercise to the Plan Administrator in accordance with the procedures specified in the Option Agreement or otherwise provided by the Company. The Board has the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The exercise price of an Option may be paid, to the extent permitted by Applicable Law and as determined by the Board, by one or more of the following methods of payment to the extent set forth in the Option Agreement:

(d) Exercise Procedure and Payment of Appreciation Distribution for SARs. In order to exercise any SAR, the Participant must provide notice of exercise to the Plan Administrator in accordance with the SAR Agreement. The appreciation distribution payable to a Participant upon the exercise of a SAR will not be greater than an amount equal to the excess of (i) the aggregate Fair Market Value on the date of exercise of a number of shares of Common Stock equal to the number of Common Stock equivalents that are vested and being exercised under such SAR, over (ii) the strike price of such SAR. Such appreciation distribution may be paid to the Participant in the form of Common Stock or cash (or any combination of Common Stock and cash) or in any other form of payment, as determined by the Board and specified in the SAR Agreement.

(e) Transferability. Options and SARs may not be transferred to third party financial institutions for value. The Board may impose such additional limitations on the transferability of an Option or SAR as it determines. In the absence of any such determination by the Board, the following restrictions on the transferability of Options and SARs will apply, provided that except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration and provided, further, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer:

(f) Vesting. The Board may impose such restrictions on or conditions to the vesting and/or exercisability of an Option or SAR as determined by the Board. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, vesting of Options and SARs will cease upon termination of the Participant’s Continuous Service.

(g) Termination of Continuous Service for Cause. Except as explicitly otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service is terminated for Cause, the Participant’s Options and SARs will terminate and be forfeited immediately upon such termination of Continuous Service, and the Participant will be prohibited from exercising any portion (including any vested portion) of such Awards on and after the date of such termination of Continuous Service and the Participant will have no further right, title or interest in such forfeited Award, the shares of Common Stock subject to the forfeited Award, or any consideration in respect of the forfeited Award.

(h) Post-Termination Exercise Period Following Termination of Continuous Service for Reasons Other than Cause. Subject to Section 4(i), if a Participant’s Continuous Service terminates for any reason other than for Cause, the Participant may exercise his or her Option or SAR to the extent vested, but only within the following period of time or, if applicable, such other period of time provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate; provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)):

(i) Restrictions on Exercise; Extension of Exercisability. A Participant may not exercise an Option or SAR at any time that the issuance of shares of Common Stock upon such exercise would violate Applicable Law. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates for any reason other than for Cause

and, at any time during the last thirty days of the applicable Post-Termination Exercise Period: (i) the exercise of the Participant’s Option or SAR would be prohibited solely because the issuance of shares of Common Stock upon such exercise would violate Applicable Law, or (ii) the immediate sale of any shares of Common Stock issued upon such exercise would violate the Company’s Trading Policy, then the applicable Post-Termination Exercise Period will be extended to the last day of the calendar month that commences following the date the Award would otherwise expire, with an additional extension of the exercise period to the last day of the next calendar month to apply if any of the foregoing restrictions apply at any time during such extended exercise period, generally without limitation as to the maximum permitted number of extensions); provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)).

(j) Non-Exempt Employees. No Option or SAR, whether or not vested, granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, will be first exercisable for any shares of Common Stock until at least six months following the date of grant of such Award. Notwithstanding the foregoing, in accordance with the provisions of the Worker Economic Opportunity Act, any vested portion of such Award may be exercised earlier than six months following the date of grant of such Award in the event of (i) such Participant’s death or Disability, (ii) a Corporate Transaction in which such Award is not assumed, continued or substituted, (iii) a Change in Control, or (iv) such Participant’s retirement (as such term may be defined in the Award Agreement or another applicable agreement or, in the absence of any such definition, in accordance with the Company’s then current employment policies and guidelines). This Section 4(j) is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay.

(k) Whole Shares. Options and SARs may be exercised only with respect to whole shares of Common Stock or their equivalents.

(a) Restricted Stock Awards and RSU Awards. Each Restricted Stock Award and RSU Award will have such terms and conditions as determined by the Board; provided, however, that each Restricted Stock Award Agreement and RSU Award Agreement will conform (through incorporation of the provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

(b) Performance Awards. With respect to any Performance Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, the other terms and conditions of such Award, and the measure of whether and to what degree such Performance Goals have been attained will be determined by the Board.

(c) Other Awards. Other forms of Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value at the time of grant) may be granted either alone or in addition to Awards provided for under Section 4 and the preceding provisions of this Section 5. Subject to the provisions of the Plan, the Board will have sole and complete discretion to determine the persons to whom and the time or times at which such Other Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Awards and all other terms and conditions of such Other Awards.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately adjust: (i) the class(es) and maximum number of shares of Common Stock subject to the Plan and the maximum number of shares by which the Share Reserve may annually increase pursuant to Section 2(a); (ii) the class(es) and maximum number of shares that may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 2(a); and (iii) the class(es) and number of securities and exercise

price, strike price or purchase price of Common Stock subject to outstanding Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. Notwithstanding the foregoing, no fractional shares or rights for fractional shares of Common Stock shall be created in order to implement any Capitalization Adjustment. The Board shall determine an appropriate equivalent benefit, if any, for any fractional shares or rights to fractional shares that might be created by the adjustments referred to in the preceding provisions of this Section.

(b) Dissolution or Liquidation. Except as otherwise provided in the Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Awards (other than Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Award is providing Continuous Service, provided, however, that the Board may determine to cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

(c) Corporate Transaction. The following provisions will apply to Awards in the event of a Corporate Transaction except as set forth in Section 11, and unless otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time of grant of an Award.

(d) Appointment of Stockholder Representative. As a condition to the receipt of an Award under this Plan, a Participant will be deemed to have agreed that the Award will be subject to the terms of any agreement governing a Corporate Transaction involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on the Participant’s behalf with respect to any escrow, indemnities and any contingent consideration.

(e) No Restriction on Right to Undertake Transactions. The grant of any Award under the Plan and the issuance of shares pursuant to any Award does not affect or restrict in any way the right or power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, rights or options to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or which are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

(a) Administration by Board. The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in subsection (c) below.

(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(c) Delegation to Committee.

(d) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board or any Committee in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

(e) Delegation to Other Person or Body. The Board or any Committee may delegate to one or more persons or bodies the authority to do one or more of the following to the extent permitted by Applicable Law: (i) designate recipients, other than Officers, of Options and SARs (and, to the extent permitted by Applicable Law, other Awards), provided that no person or body may be delegated authority to grant an Award to themself; (ii) determine the number of shares subject to such Awards; and (iii) determine the terms of such Awards; provided, however, that the Board or Committee action regarding such delegation will fix the terms of such

delegation in accordance with Applicable Law, including without limitation Sections 152 and 157 of the Delaware General Corporation Law. Unless provided otherwise in the Board or Committee action regarding such delegation, each Award granted pursuant to this section will be granted on the applicable form of Award Agreement most recently approved for use by the Board or the Committee, with any modifications necessary to incorporate or reflect the terms of such Award.

(f) Cancellation and Re-Grant of Awards. Neither the Board nor any Committee will have the authority to (i) reduce the exercise or strike price of any outstanding Option or SAR or (ii) cancel any outstanding Option or SAR that has an exercise or strike price (per share) greater than the then-current Fair Market Value of the Common Stock in exchange for cash or other Awards under the Plan, unless the stockholders of the Company have approved such an action within 12 months prior to such an event.

(g) Dividends and Dividend Equivalents. Notwithstanding any other provision in this Plan, (i) no dividends or dividend equivalents may be paid with respect to any such shares before the date such shares have vested under the terms of such Award Agreement, (ii) any dividends or dividend equivalents that are credited with respect to any such shares will be subject to all of the terms and conditions applicable to such shares under the terms of such Award Agreement (including, but not limited to, any vesting conditions), and (iii) any dividends or dividend equivalents that are credited with respect to any such shares will be forfeited to the Company on the date, if any, such shares are forfeited to or repurchased by the Company due to a failure to meet any vesting conditions under the terms of such Award Agreement.

(a) Withholding Authorization. As a condition to acceptance of any Award under the Plan, a Participant authorizes withholding from payroll and any other amounts payable to such Participant, and otherwise agrees to make adequate provision for (including), any sums required to satisfy any U.S. federal, state, local and/or foreign tax or social insurance contribution withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise, vesting or settlement of such Award, as applicable. Accordingly, a Participant may not be able to exercise an Award even though the Award is vested, and the Company shall have no obligation to issue shares of Common Stock subject to an Award, unless and until such obligations are satisfied.

(b) Satisfaction of Withholding Obligation. To the extent permitted by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any U.S. federal, state, local and/or foreign tax or social insurance withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; (v) by allowing a Participant to effectuate a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board; or (vi) by such other method as may be set forth in the Award Agreement.

(c) No Obligation to Notify or Minimize Taxes; No Liability to Claims. Except as required by Applicable Law the Company has no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Award. Furthermore, the Company has no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award and will not be liable to any holder of an Award for any adverse tax consequences to such holder in connection with an Award. As a condition to accepting an Award under the Plan, each Participant (i) agrees to not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from such Award or other Company compensation and (ii) acknowledges that such Participant was advised to consult with his or her own personal tax, financial and other legal advisors regarding the tax consequences of the Award and has either done so or knowingly and voluntarily declined to do so. Additionally, each Participant acknowledges any Option or SAR granted under the Plan is exempt from Section 409A only if the exercise or strike price is at least equal to the “fair market value” of the Common Stock on the date of grant as determined by the Internal Revenue Service and there is no other impermissible deferral of compensation associated with the Award. Additionally, as a condition to accepting an Option or SAR

granted under the Plan, each Participant agrees not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the Internal Revenue Service asserts that such exercise price or strike price is less than the “fair market value” of the Common Stock on the date of grant as subsequently determined by the Internal Revenue Service.

(d) Withholding Indemnification. As a condition to accepting an Award under the Plan, in the event that the amount of the Company’s and/or its Affiliate’s withholding obligation in connection with such Award was greater than the amount actually withheld by the Company and/or its Affiliates, each Participant agrees to indemnify and hold the Company and/or its Affiliates harmless from any failure by the Company and/or its Affiliates to withhold the proper amount.

(a) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.

(b) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Awards will constitute general funds of the Company.

(c) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action approving the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the Award Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.

(d) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Award unless and until (i) such Participant has satisfied all requirements for exercise of the Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Award is reflected in the records of the Company.

(e) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or affect the right of the Company or an Affiliate to terminate at will and without regard to any future vesting opportunity that a Participant may have with respect to any Award (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state or foreign jurisdiction in which the Company or the Affiliate is incorporated, as the case may be. Further, nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award will constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or service or confer any right or benefit under the Award or the Plan unless such right or benefit has specifically accrued under the terms of the Award Agreement and/or Plan.

(f) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the Participant, the Board may determine, to the extent permitted by Applicable Law, to (i) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended.

(g) Execution of Additional Documents. As a condition to accepting an Award under the Plan, the Participant agrees to execute any additional documents or instruments necessary or desirable, as determined in the Plan Administrator’s sole discretion, to carry out the purposes or intent of the Award, or facilitate compliance with securities and/or other regulatory requirements, in each case at the Plan Administrator’s request.

(h) Electronic Delivery and Participation. Any reference herein or in an Award Agreement to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access). By accepting any Award, the Participant consents to receive documents by electronic delivery and to participate in the Plan through any on-line electronic system established and maintained by the Plan Administrator or another third party selected by the Plan Administrator. The form of delivery of any Common Stock (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company.

(i) Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Law and any clawback policy that the Company otherwise adopts, to the extent applicable and permissible under Applicable Law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a Participant’s right to voluntary terminate employment upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company.

(j) Securities Law Compliance. A Participant will not be issued any shares in respect of an Award unless either (i) the shares are registered under the Securities Act; or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Each Award also must comply with other Applicable Law governing the Award, and a Participant will not receive such shares if the Company determines that such receipt would not be in material compliance with Applicable Law.

(k) Transfer or Assignment of Awards; Issued Shares. Except as expressly provided in the Plan or the form of Award Agreement, Awards granted under the Plan may not be transferred or assigned by the Participant. After the vested shares subject to an Award have been issued, or in the case of Restricted Stock and similar awards, after the issued shares have vested, the holder of such shares is free to assign, hypothecate, donate, encumber or otherwise dispose of any interest in such shares provided that any such actions are in compliance with the provisions herein, the terms of the Trading Policy and Applicable Law.

(l) Effect on Other Employee Benefit Plans. The value of any Award granted under the Plan, as determined upon grant, vesting or settlement, shall not be included as compensation, earnings, salaries, or other similar terms used when calculating any Participant’s benefits under any employee benefit plan sponsored by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company's or any Affiliate's employee benefit plans.

(m) Deferrals. To the extent permitted by Applicable Law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may also establish programs and procedures for deferral elections to be made by Participants. Deferrals by will be made in accordance with the requirements of Section 409A.

(n) Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A, and, to the extent not so exempt, in compliance with the requirements of Section 409A. If the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a

Participant holding an Award that constitutes “deferred compensation” under Section 409A is a “specified employee” for purposes of Section 409A, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A without regard to alternative definitions thereunder) will be issued or paid before the date that is six months and one day following the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule.

(o) Choice of Law. This Plan and any controversy arising out of or relating to this Plan shall be governed by, and construed in accordance with, the internal laws of the State of Delaware, without regard to conflict of law principles that would result in any application of any law other than the law of the State of Delaware.

(a) Compliance with Law. The Company will seek to obtain from each regulatory commission or agency, as may be deemed to be necessary, having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon exercise or vesting of the Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary or advisable for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise or vesting of such Awards unless and until such authority is obtained. A Participant is not eligible for the grant of an Award or the subsequent issuance of Common Stock pursuant to the Award if such grant or issuance would be in violation of any Applicable Law.

(a) Application. Unless the provisions of this Section of the Plan are expressly superseded by the provisions in the form of Award Agreement, the provisions of this Section shall apply and shall supersede anything to the contrary set forth in the Award Agreement for a Non-Exempt Award.

(b) Non-Exempt Awards Subject to Non-Exempt Severance Arrangements. To the extent a Non-Exempt Award is subject to Section 409A due to application of a Non-Exempt Severance Arrangement, the following provisions of this subsection (b) apply.

Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant will have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose.

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written

agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply.

However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person.

(q) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in the Entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law. In addition, to the extent required for exemption from or compliance with Section 409A, the determination of whether there has been a termination of Continuous Service will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder).

(v) “Effective Date” means the date on which the Plan was approved by the Company’s stockholders.

A Participant's rights under an Award will not be deemed to have been Materially Impaired by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant's rights. For example, the following types of amendments to the terms of an Award do not Materially Impair the Participant’s rights under the Award: (i) imposition of reasonable restrictions on the minimum number of shares subject to an Option that may be exercised; (ii) to maintain the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (iii) to change the terms of an Incentive Stock Option in a manner that disqualifies, impairs or otherwise affects the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (iv) to clarify the manner of exemption from, or to bring the Award into compliance with or qualify it for an exemption from, Section 409A; or (v) to comply with other Applicable Laws.

(a) The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem appropriate, and will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8, inclusive.

(b) If a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise indicates in forms delivered to the Company: (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices) will be exercised.

(c) The Board will have the discretion to structure an Offering so that if the Fair Market Value of a share of Common Stock on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for that Offering, then (i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase Period.

(a) Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to Employees of a Related Corporation. Except as provided in Section 5(b), an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee has been in the employ of the Company or the Related Corporation, as the case may be, for such continuous period preceding such Offering Date as the Board may require, but in no event will the required period of continuous employment be equal to or greater than two years. In addition, the Board may provide that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such Employee’s customary employment with the Company or the Related Corporation is more than 20 hours per week and more than five months per calendar year or such other criteria as the Board may determine consistent with Section 423 of the Code.

(b) The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such

person becomes an Eligible Employee or which occurs thereafter, receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that Offering, as described herein, except that:

(i) the date on which such Purchase Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right;

(ii) the period of the Offering with respect to such Purchase Right will begin on its Offering Date and end coincident with the end of such Offering; and

(iii) the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Purchase Right under that Offering.

(c) No Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase Rights are granted, such Employee owns stock possessing five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase Rights and options will be treated as stock owned by such Employee.

(d) As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase stock of the Company or any Related Corporation to accrue at a rate which exceeds $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time.

(e) Officers of the Company and any designated Related Corporation, if they are otherwise Eligible Employees, will be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code will not be eligible to participate.

(a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock purchasable either with a percentage or with a maximum dollar amount, as designated by the Board, but in either case not exceeding 15% of such Employee’s earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering.

(b) The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised and shares of Common Stock will be purchased in accordance with such Offering.

(c) In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants pursuant to such Offering and/or (iii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of shares of Common Stock issuable upon exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of the shares of Common Stock available will be made in as nearly a uniform manner as will be practicable and equitable.

(d) The purchase price of shares of Common Stock acquired pursuant to Purchase Rights will be not less than the lesser of:

(i) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or

(ii) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the applicable Purchase Date.

(a) An Eligible Employee may elect to authorize payroll deductions as the means of making Contributions by completing and delivering to the Company, within the time specified in the Offering, an enrollment form provided by the Company. The enrollment form will specify the amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the Company except where applicable law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first payroll occurring on or after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If specifically provided in the Offering, in addition to making Contributions by payroll deductions, a Participant may make Contributions through the payment by cash or check prior to a Purchase Date.

(b) During an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute to such Participant all of his or her accumulated but unused Contributions and such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings.

(c) Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation period required by law) or (ii) is otherwise no longer eligible to participate. The Company will distribute to such individual all of his or her accumulated but unused Contributions.

(d) During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10.

(e) Unless otherwise specified in the Offering, the Company will have no obligation to pay interest on Contributions.

(a) On each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of shares of Common Stock, up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will be issued unless specifically provided for in the Offering.

(b) If any amount of accumulated Contributions remains in a Participant’s account after the purchase of shares of Common Stock and such remaining amount is less than the amount required to purchase one share of Common Stock on the final Purchase Date of an Offering, then such remaining amount will be held in such Participant’s account for the purchase of shares of Common Stock under the next Offering under the Plan, unless such Participant withdraws from or is not eligible to participate in such Offering, in which case such amount will be distributed to such Participant after the final Purchase Date, without interest. If the amount of Contributions remaining in a Participant’s account after the purchase of shares of Common Stock is at least equal to the amount required to purchase one whole share of Common Stock on the final Purchase Date of an Offering, then

such remaining amount will not roll over to the next Offering and will instead be distributed in full to such Participant after the final Purchase Date of such Offering without interest.

(c) No Purchase Rights may be exercised to any extent unless the shares of Common Stock to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable federal, state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the Purchase Date will be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than 6 months from the Offering Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are not registered and the Plan is not in material compliance with all applicable laws, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed to the Participants without interest.

The Company will seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock thereunder. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale of Common Stock under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Common Stock upon exercise of such Purchase Rights.

(a) The Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any shares of Common Stock and/or Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company.

(b) If a Participant dies, in the absence of a valid beneficiary designation, the Company will deliver any shares of Common Stock and/or Contributions to the executor or administrator of the estate of the Participant. If, to the knowledge of the Company, no executor or administrator has been appointed, the Company, in its sole discretion, may deliver such shares of Common Stock and/or Contributions to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

(a) In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iii) the class(es) and number of securities that are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive.

(b) In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration paid to the stockholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common Stock within ten business days prior to the Corporate Transaction under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase.

(a) The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, stockholder approval will be required for any amendment of the Plan for which stockholder approval is required by applicable law or listing requirements, including any amendment that either (i) materially increases the number of shares of Common Stock available for issuance under the Plan, (ii) materially expands the class of individuals eligible to become Participants and receive Purchase Rights, (iii) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which shares of Common Stock may be purchased under the Plan, (iv) materially extends the term of the Plan, or (v) expands the types of awards available for issuance under the Plan, but in each of (i) through (v) above only to the extent stockholder approval is required by applicable law or listing requirements.

(b) The Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the Plan is suspended or after it is terminated.

(c) Any benefits, privileges, entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by the Board, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right and/or the Plan complies with the requirements of Section 423 of the Code.

The Plan will become effective immediately prior to and contingent upon the IPO Date. No Purchase Rights will be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the Plan is adopted (or if required under Section 12(a) above, materially amended) by the Board.

(a) Proceeds from the sale of shares of Common Stock pursuant to Purchase Rights will constitute general funds of the Company.

(b) A Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, shares of Common Stock subject to Purchase Rights unless and until the Participant’s shares of Common Stock acquired upon exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent).

(c) The Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering will in any way alter the at will nature of a Participant’s employment or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue in the employ of the Company or a Related Corporation, or on the part of the Company or a Related Corporation to continue the employment of a Participant.

(d) The provisions of the Plan will be governed by the laws of the State of California without resort to that state’s conflicts of laws rules.
