3


Shares of common stock held by persons attending the annual meeting but not voting, and shares represented by proxies that reflect abstentions as to a particular proposal, will be counted as present for purposes of determining the presence of a quorum. Abstentions are treated as shares present in person or by proxy and entitled to vote, so abstaining has the same effect as a negative vote for purposes of determining whether our stockholders have ratified the appointment of Ernst & Young LLP, our independent registered public accounting firm, and whether our stockholders have approved a one-time stock option exchange program.the compensation of the named executive officers, and the amendment and restatement of our Employee Stock Purchase Plan. However, because the election of directors is determined by a plurality of votes cast, abstentions will not be counted in determining the outcome of such proposal.
Shares represented by proxies that reflect a “broker non-vote” will be counted for purposes of determining whether a quorum exists. A “broker non-vote” occurs when a nominee holding shares for a beneficial owner has not received instructions from the beneficial owner and does not have discretionary authority to vote the shares for certain non-routine matters. With regard to the election of directors and the approvaladvisory vote to approve the compensation of a one-time stock option exchange program,the named executive officers, broker non-votes, if any, will not be counted as votes cast and will have no effect on the result of the vote. However, ratification of the appointment of Ernst & Young LLP isand the amendment and restatement of our Employee Stock Purchase Plan are considered a routine mattermatters on which a broker or other nominee has discretionary authority to vote. As a result, broker non-votes will be counted for purposes of this proposal.these proposals.

We will pay all of the costs of soliciting these proxies. Our directors, officers and other employees may solicit proxies in person or by telephone, fax or email. We will not pay our directors, officers or other employees any additional compensation for these services.

Independence of the Board of Directors
As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. In addition, Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees be independent within the meaning of Nasdaq rules. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act.
Our Board undertook a review of the independence of each director and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board determined that each of our current directors, are, independent directorsother than Stephen J. Farr, Ph.D.,

Breitmeyer, M.D., Ph.D. and Stephen J. Farr, Ph.D., our Chief Executive Officer and President.rules.
Board Leadership Structure
Our board of directors is currently led by its chairman, Cam L. Garner. Our board of directors recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the company continues to grow. We separate the roles of chief executive officer and chairman of the board in recognition of the differences between the two roles. The chief executive officer is responsible for setting the strategic direction for the company and the day-to-day leadership and performance of the company, while the chairman of the board of directors provides guidance to the chief executive officer and presides over meetings of the full board of directors. We believe that this separation of responsibilities provides a balanced approach to managing the board of directors and overseeing the company.
The Board’s Role in Risk Oversight
Our board of directors has responsibility for the oversight of the company’s risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from board committees and members of senior management to enable our board to understand the company’s risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk.
The audit committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the audit committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the audit committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The compensation committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The nominating/corporate governance committee manages risks associated with the independence of the board, corporate disclosure practices, and potential conflicts of interest. While each committee is responsible for

8



evaluating certain risks and overseeing the management of such risks, the entire board is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our board as a whole.

During 2015,2019, our board of directors met eightsix times, including telephonic meetings, and in that year, all incumbent directors attended at least 75% of the aggregate number of meetings of the board and the committees on which they served, during the periods in which they served.

Report of the Audit Committee of the Board of Directors
The audit committee oversees the company’s financial reporting process on behalf of our board of directors.

Compensation Committee Interlocks and Insider Participation
Cam L.Mr. Garner Louis C. Bock(former chairman and Markcommittee member), Mr. Wiggins (current chairman) and Drs. Breitmeyer and Tannenbaum served on ourthe compensation committee during 2015.2019. None of the members of our compensation committee has ever been one of our officers or employees. None of our executive officers currently serves, or has

11



served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.
Director Nomination Process
Director Qualifications
In evaluating director nominees the nominating/corporate governance committee will consider among other things the following factors:
10


personal and professional integrity, ethics and values;
personal and professional integrity, ethics and values;
experience in corporate management, such as serving as an officer or former officer of a publicly-held company;
commercialization experience in large pharmaceutical companies;
experience in corporate management, such as serving as an officer or former officer of a publicly held company;
strong finance experience;
experience relevant to our industry;
experience as a board member of another publicly held company;
commercialization experience in large pharmaceutical companies;
diversity of expertise and experience in substantive matters pertaining to our business relative to other board members;
diversity of background and perspective, including with respect to age, gender, race, place of residence and specialized experience; and
strong finance experience;
experience relevant to our industry;
experience as a board member of another publicly held company;
diversity of expertise and experience in substantive matters pertaining to our business relative to other board members;
diversity of background and perspective, including with respect to age, gender, race, place of residence and specialized experience; and
practical and mature business judgment.
practical and mature business judgment.
The nominating/corporate governance committee’s goal is to assemble a board of directors that brings to the company a variety of perspectives and skills derived from high quality business and professional experience. Moreover, the nominating/corporate governance committee believes that the background and qualifications of the board of directors, considered as a group, should provide a significant mix of experience, knowledge and abilities that will allow the board of directors to fulfill its responsibilities. Nominees are not discriminated against on the basis of race, religion, national origin, sexual orientation, disability or any other basis proscribed by law.
Other than the foregoing criteria for director nominees, the nominating/corporate governance committee has not adopted a formal policy with respect to a fixed set of specific minimum qualifications for its candidates for membership on the board of directors. The nominating/corporate governance committee may consider such other facts, including, without limitation, diversity, as it may deem are in the best interests of the company and its stockholders. The nominating/corporate governance committee does, however, believe it is appropriate for at least one, and, preferably, several, members of our board of directors to meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of our board of directors be independent as required under the Nasdaq qualification standards. The nominating/corporate governance committee also believes it is appropriate for our President and Chief Executive Officer to serve as a member of our board of directors. Our directors’ performance and qualification criteria are reviewed annually by the nominating/corporate governance committee.
Identification and Evaluation of Nominees for Directors
The nominating/corporate governance committee identifies nominees for director by first evaluating the current members of our board of directors willing to continue in service. Current members with qualifications and skills that are consistent with the nominating/corporate governance committee’s criteria for board of director service and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of our board of directors with that of obtaining a new perspective or expertise.

12



If any member of our board of directors does not wish to continue in service or if our board of directors decides not to re-nominate a member for re-election, the nominating/corporate governance committee may identify the desired skills and experience of a new nominee in light of the criteria above, in which case, the nominating/corporate governance committee would generally poll our board of directors and members of management for their recommendations. The nominating/corporate governance committee may also review the composition and qualification of the boards of directors of our competitors, and may seek input from industry experts or analysts. The nominating/corporate governance committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the members of the nominating/corporate governance committee and by certain of our other independent directors and executive management. In making its determinations, the nominating/corporate governance committee evaluates each individual in the context of our board of directors as a whole, with the objective of assembling a group that can best contribute to the success of our company and represent stockholder interests through the exercise of sound judgment. After review and deliberation of all feedback and data, the nominating/corporate governance committee makes its recommendation to our board of directors. The nominating/corporate governance committee has utilized the third-party search firm of Spencer Stuart to assist with the identification of qualified board of director candidates.
The nominating/corporate governance committee evaluates nominees recommended by stockholders in the same manner as it evaluates other nominees. We have not received director candidate recommendations from our stockholders and do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by board members, management or other parties are evaluated. We do not intend to treat stockholder recommendations in any manner different from other recommendations.
Under our amended and restated bylaws, stockholders wishing to suggest a candidate for director should write to our corporate secretary and provide such information about the stockholder and the proposed candidate as is set forth in our amended and restated bylaws and as would be required by SEC rules to be included in a proxy statement. In addition, the stockholder must include the
11


consent of the candidate and describe any arrangements or undertakings between the stockholder and the candidate regarding the nomination. In order to give the nominating/corporate governance committee sufficient time to evaluate a recommended candidate and/or include the candidate in our proxy statement for the 20162021 annual meeting, the recommendation should be received by our corporate secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled “Stockholder Proposals.”
Director Attendance at Annual Meetings

The corporate secretary will forward such communications to each member of our board of directors; provided that, if in the opinion of our corporate secretary it would be inappropriate to send a particular stockholder communication to a specific director, such communication will only be sent to the remaining directors (subject to the remaining directors concurring with such opinion).

PROPOSAL 3:
APPROVAL, ON AN ADVISORY BASIS, OF A ONE-TIME STOCK OPTION EXCHANGE PROGRAMTHE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our stockholders are entitled to vote at the annual meeting to provide advisory approval of the compensation of our named executive officers as disclosed in this proxy statement pursuant to the compensation disclosure rules of the SEC. Pursuant to the Dodd-Frank Act, the stockholder vote on executive compensation is an advisory vote only, and it is not binding on us or our board of directors.

Although the vote is non-binding, our compensation committee and board of directors value the opinions of the stockholders and will consider the outcome of the vote when making future compensation decisions. As described more fully in the Compensation Discussion and Analysis section of this proxy statement, our executive compensation program is designed to attract, retain and motivate individuals with superior ability, experience and leadership capability to deliver on our annual and long-term business objectives necessary to create stockholder value. We urge stockholders to read the Compensation Discussion and Analysis section of this proxy statement, which describes in detail how our executive compensation policies and procedures operate and are intended to operate in the future. The compensation committee and the board of directors believe that our executive compensation program fulfills these goals and is reasonable, competitive and aligned with our performance and the performance of our executives.
We are asking our stockholders to approve a one-time stock option exchange program. If implemented, this one-time stock option exchange program, or option exchange, would allow us to cancel eligible stock options, referred to hereinindicate their support for our named executive officer compensation as eligible options, held by certain of our employees and consultants, referred to herein as eligible participants, in exchange for a lesser number of replacement stock options, referred to herein as replacement options, with lower exercise prices to be granted under the Zogenix, Inc. 2010 Equity Incentive Award Plan, or the 2010 Plan. Members of our board of directors and our Chief Executive Officer will not be eligible participants in the option exchange.

Our board of directors, upon the recommendation of our compensation committee, has determined that it would be in the best interests of the company and our stockholders to implement the option exchange on the terms and conditions described in detail below, subject to the exceptions described in this proxy statement. This proposal, subjectcommonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to stockholder approval.

In designingexpress their views on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the option exchange, we have taken into account our stockholders’ interests and designed the option exchange to include a number of stockholder-favorable features, such as:

Our Chief Executive Officer and board members will not be eligible to participate in the option exchange.Membersoverall compensation of our board of directorsnamed executive officers and the philosophy, policies and practices described in this proxy statement. Accordingly, we ask that our Chief Executive Officer will be excluded from participating instockholders vote “FOR” the option exchange. Although members of our board of directors and our Chief Executive Officer also hold optionsfollowing resolution:
“RESOLVED, that are significantly underwater, these individuals are not eligible to participate in the option exchange because we believe that their compensation should remain at greater risk basedZogenix, Inc.’s stockholders approve, on our stock price. All other eligible employees and consultants of our company and our subsidiaries holding eligible options will generally be eligible to participate.

Eligible options must be significantly underwater. Only stock options with exercise prices that are greater than a specified percentage above the fair market value of our stock price as measured at the option exchange’s commencement date, which percentage will be determined byan advisory basis, the compensation committee but will not be less than 25%, will be eligible to participate in the option exchange.

Replacement options will be subject to new vesting terms. All replacement options will be unvested upon grant and subject to new vesting requirements. Eligible option grants that are fully vested on the date of the exchange will be exchangednamed executive officers, as disclosed in Zogenix, Inc.’s Proxy Statement for replacement options that will vest monthly over two years following the replacement grant date. Eligible option grants that are not fully vested on the date2020 Annual Meeting of the exchange will be exchanged for replacement options that will vest monthly over three years following the replacement grant date. Vesting will be subject to the participant’s continued service through the vesting date.

Value-for-value exchange. The option exchange will not be a one-for-one exchange. Instead, it will more closely approximate a value-for-value exchange of the eligible options for new replacement options. Our compensation committee will set the exchange ratios (as defined below) shortly prior to the commencement of the option exchange with the intent that the fair value of the replacement options to be granted will be approximately equal to the fair value of the eligible options that are surrendered under Accounting Standards Codification Topic 718 (“ASC 718”), “Compensation-Stock Compensation.” The methodology and assumptions to be used to value the cancelled eligible options and replacement options and set the exchange ratios are set forth below under “Exchange Ratios.”

Reduction in issued equity awards overhang. Because a lesser number of shares will be subject to awards granted in exchange for eligible options, the number of shares of common stock subject to all outstanding equity awards will be reduced following the option exchange, thereby reducing our equity award overhang.

Reduced number of shares subject to replacement options will conserve equity pool. The reduced number of shares subject to the replacement options will conserve our equity pool. Under the option exchange,Stockholders, pursuant to the termscompensation disclosure rules of the 2010 Plan, shares subject to eligible options that were originally granted underSEC, including the 2010 Plan orCompensation Discussion and Analysis, the Zogenix, Inc. 2006 Equity Incentive Plan, or the 2006 Plan, that are surrendered in exchange for a lesser number of replacement options will automatically return to the pool of shares available for future grant under our 2010 Plan. This return of shares will constitute an efficient use of the shares available for future issuance. Shares subject to eligible options that were originally granted under the Zogenix, Inc. 2013 Employment Inducement Equity Incentive Plan, or the 2013 Plan, will be cancelled at the time of the option exchange2019 Summary Compensation Table and the shares subject to such surrendered options will not be available for future issuance under the 2013 Plan.

Voluntarily seeking stockholder approval. We are voluntarily seeking stockholder approval of the option exchange. Stockholder approval of the option exchange is not required under the NASDAQ listing rules or under the terms of our 2010

18



Plan, the 2006 Plan or the 2013 Plan, collectively referred to herein as the Plans.

If our stockholders approve this proposal, and our board of directors or compensation committee determines to implement the option exchange, we expect the option exchange would be scheduled to commence in the third quarter of 2016. However, our board of directors or compensation committee may, in their sole discretion, determine to postpone the actual start date of the option exchange to a date within 12 months of the date of the annual meeting.

If our stockholders do not approve this proposal, we will not implement the option exchange and the eligible options will continue in accordance with their terms.

Reasons for the Option Exchange

We believe that to be successful, our key contributors need to think like owners. Consistent with this philosophy, our equity program is broad-based. This broad-based equity program provides us with a competitive advantage, particularly in our efforts to attract and retain top talent in our industry.
During this past year, we have changed the focus of our company from a commercial organization to a development company, requiring us to reduce our headcount and hire employees and leaders with different knowledge and skills. This transition has threatened the retention of some of our most senior and veteran employees and has created the need for a more robust compensation package. In addition, over half of our management team has been with the company in excess of seven years, yet have little or no value in their equity awards.
Over the last several years, we have experienced a significant decline in our stock price. Although we continue to aggressively manage our business to maximize our financial and stock price performance, our stock price remains at a low level compared to its historical prices. As a result, a considerable number of eligible participants hold “underwater” stock options with exercise prices significantly above the recent trading prices of our common stock. At the same time, the market for key talent remains extremely competitive and our board of directors believes that retaining our employees and consultants is critical to our future success. We believe that many eligible participants perceive that their options have little or no value. As a result, these underwater stock options are no longer effective as incentives to retain and motivate our key contributors.
In addition, although these stock options are not likely to be exercised as long as our stock price is lower than the applicable exercise price, they will remain on our books with the potential to dilute stockholders’ interests for up to the full term of the options, while delivering little or no retentive or incentive value, unless they are surrendered or cancelled.

Additionally, under applicable accounting rules, we are required to continue to recognize compensation expense related to these options while they remain outstanding, even if they are never exercised.
As of April 30, 2016, we had an aggregate of 3,184,088 shares underlying outstanding stock options under the Plans, of which 76,957 were held by former employees, and approximately 99% of the outstanding options were underwater (based on the closing price per share of our common stock of $10.25 on April 29, 2016). Of these options, 1,238,052, or approximately 40%, had exercise prices per share in excess of $13.00, were held by current employees or consultants other than our Chief Executive Officer and board of directors, and would have been considered “eligible options” under the assumptions outlined below had the option exchange commenced on April 30, 2016. As of April 30, 2016, our Chief Executive Officer and the members of our board of directors held stock options to purchase an aggregate of 1,170,447 shares, which options will not be eligible to participate in the option exchange.

The following table summarizes the effect of the option exchange under the Plans, assuming a fair market value of our common stock of $10.25 (the closing price per share of our common stock on April 29, 2016) for the valuation of the eligible options immediately prior to cancellation and for the valuation of the replacement options granted as a result of the option exchange, the determination of the exchange ratios pursuant to the methodology described below, a $13.00 per share exercise price eligibility threshold and a commencement date of April 30, 2016. If the price per share of our common stock is lower than $10.25 when we commence the option exchange, additional options held by eligible participants with exercise prices lower than $13.00 may become eligible options (but in no event may more than 1,936,684 options be eligible options, based on the options outstanding as of April 30, 2016).

Alternatives Considered. Beginning in March 2015, our board of directors and compensation committee began to consider retention issues associated with the reduced trading price of our common stock relative to exercise prices of outstanding stock options. Radford, an AonHewitt company (“Radford”), an independent compensation consulting firm, was retained by the compensation committee in evaluating issues associated with underwater stock options and in structuring a compensation program designed to retain and provide incentives to individuals holding underwater options. Over the course of the past year, we evaluated several alternatives with Radford, including increasing cash compensation and/or granting additional equity awards. We have implemented each of these alternatives to a degree, but do not believe that relying exclusively on such approaches is optimal.

Relying entirely on increasing cash compensation would substantially increase our compensation expenses and reduce our cash flow from operations. Also, we believe that equity is an essential component of compensation to optimize our ability to hire and retain talented individuals, particularly in the competitive labor market in which we operate. Relying entirely on grants of additional stock options at current market prices or restricted stock units, referred to herein as RSUs, would substantially increase our overhang and cause dilution to our stockholders.

We also considered an exchange program in which underwater stock options would be exchanged for a lesser number of RSUs. The compensation committee and Radford performed a comprehensive evaluation of the positive and negative attributes of an option-for-RSU exchange program. As part of this evaluation, the compensation committee identified the likely participants of an option-for-RSU exchange program and discussed the value of the exchanged equity awards, the general parameters of an option-for-RSU exchange program and the probable effects of an option-for-RSU exchange program on our current hiring plans and retention goals. However, in order to ensure that the option-for-RSU exchange program is approximately expense-neutral from an accounting perspective, the exchange ratios for such an exchange program would need to be substantially higher than for an option-for-option exchange program (i.e., fewer replacement awards granted). Thus, we believe that participation in an option-for-RSU exchange program would be lower than with an option-for-option exchange program. Additionally, RSUs would be a new form of equity award for many of the eligible participants and we believe that a lack of familiarity with such equity awards could negatively impact participation in the exchange program.

Advantages of an Option-for-Option Exchange. After weighing each of these alternatives, our compensation committee recommended, and our board of directors approved, an option-for-option exchange on the terms and conditions described in this Proposal 3, subject to the exceptions described in this proposal. We have determined that a program under which eligible participants generally could exchange significantly underwater stock options for a smaller number of stock options was the most attractive alternative for a number of reasons, including the following:

The option exchange offers a reasonable, balanced and meaningful incentive for eligible participants. Under the option exchange, eligible participants would surrender eligible options for a smaller number of stock options that will vest over two or three years, depending on whether the grant that is surrendered is fully vested at the time of surrender. Eligible option grants that are fully vested on the date of the exchange will be exchanged for replacement options that will vest monthly over two years following the replacement grant date. Eligible option grants that are not fully vested on the date of the exchange will be exchanged for replacement options that will vest monthly over three years following the replacement grant date. We believe that the lower number of stock options granted, together with a new vesting requirement, represents a reasonable and balanced option exchange with the potential for a significant positive impact on retention, motivation and performance. Additionally, stock options will provide value to eligible participants only if our share price increases over time, thereby aligning eligible participant and stockholder interests.

The option exchange will help to restore retention and motivation incentives. We rely on skilled and educated, technical, and managerial employees and consultants. Competition for these types of employees and consultants is intense. We continue to believe that equity awards are an important component of our compensation program and our ability to retain and motivate our key contributors. We also believe that substantially underwater options do not have sufficient impact on retention and motivation, and that for our stock options to serve their intended purposes, they need to be exercisable at least near the current trading prices of our common stock. The failure to address the underwater option issue in the near to medium term will make it more difficult for us to retain our key contributors. If we cannot retain these individuals, our business, results of operations and future stock price could be adversely affected. We believe that the new replacement options will be more effective in retaining and incentivizing eligible participants than the existing underwater options. Additionally, replacement options will have a two-year or three-year vesting schedule. The company believes that this vesting schedule will provide a strong incentive for employees and consultants to remain with the company and will largely alleviate the need to find other extraordinary compensatory measures to retain key contributors.

The option exchange will align compensation costs with the retention and motivation value of the equity awards. Our

21



underwater options have exercise prices that were equal to the fair market value of our common stock at the time of grant. Under applicable accounting rules, we are required to continue to recognize compensation expense related to these grants while they remain outstanding, even if they are never exercised. We believe that it is an inefficient use of corporate resources to recognize compensation expense on awards that are not valued by our employees and consultants. By replacing underwater options that have diminished retention or incentive value with new replacement options that will provide both enhanced retention and incentive value while incurring only minimal incremental compensation expense as described below, we will be able to use our compensation tools more efficiently.

If there is significant participation in the option exchange, the option exchange will reduce our equity award overhang. Not only do the underwater options have little or no retention value, they cannot be removed from our equity award overhang until they are exercised, expire or otherwise terminate (for example, when an employee or consultant leaves the company). The option exchange will reduce our equity award overhang while eliminating the ineffective options that are currently outstanding. Because a lesser number of shares will be subject to awards granted in exchange for eligible options, the number of shares of stock subject to all outstanding equity awards will be reduced following the option exchange, thereby reducing our equity award overhang.

The reduced number of shares subject to the replacement options will conserve our equity pool. Under the terms of the 2010 Plan, any surrendered eligible options that were originally granted under the 2010 Plan or the 2006 Plan automatically will be reserved for future issuance under the 2010 Plan as a result of the cancellation of such options pursuant to the option exchange. This return of shares will constitute an efficient use of the shares available for future issuance. Shares subject to eligible options that were originally granted under the 2013 Plan will be cancelled at the time of the option exchange and the shares subject to such surrendered options will not be available for future issuance under the 2013 Plan.

The option exchangewill decrease pressure for additional grants. If we are unable to conduct an option exchange in which underwater options with diminished incentive value may be exchanged for a lesser number of new replacement options with higher motivation and retentive value, we may find it necessary to issue significant additional options or other equity awards to employees and consultants above and beyond our ongoing equity grant practices in order to provide renewed incentive to employees and consultants.

Details of the Option Exchange

Eligibility. The option exchange will be open to all employees and consultants of the company and its subsidiaries (but excluding our Chief Executive Officer and members of our board of directors) who are employed by or providing services to us at the start of the option exchange and hold eligible options. In addition to being an eligible participant as of the start of the option exchange, an individual will only be eligible to participate in the option exchange if he or she continues to provide services to us through the replacement grant date. If an eligible participant is no longer an employee or consultant with us for any reason on the replacement grant date, even if he or she had elected to participate and had tendered his or her eligible options for exchange, such eligible participant’s options will automatically be deemed withdrawn and he or she will not participate in the option exchange. The board of directors will have the authority to exclude otherwise eligible employees and consultants in non-U.S. jurisdictions if it determines that local law or other constraints make the participation of employees or consultants in a certain country infeasible or impractical. As of April 30, 2016, we estimate that approximately 61 employees and 1 consultant will be eligible to participate in the option exchange. As of April 30, 2016, we had a total of 64 employees, approximately 15 consultants, and 7 non-employee directors. We will not make the option exchange available to former employees or former consultants. A vote by an eligible participant in favor of this proposal at the annual meeting does not constitute an election to participate in the option exchange.

Eligible Options.The only options that eligible participants may exchange in the option exchange are those outstanding options under the Plans held by an eligible participant that have a per share exercise price greater than a specified percentage above the fair market value of our stock price as measured at the option exchange’s commencement date or a date shortly before the commencement date as determined by our compensation committee, which percentage will be determined by the compensation committee but will not be less than 25%. Our intent in using an exercise price eligibility threshold is to ensure that only outstanding options that are significantly underwater are eligible for the option exchange.

If the trading price of our common stock increases to a price higher than the exercise price eligibility threshold at the date of closing of the option exchange, tendered options having an exercise price lower than such trading price automatically will be withdrawn from the offer and will not be exchanged for options having a higher exercise price. All eligible options that are not exchanged will remain outstanding and in effect in accordance with their existing terms.

If an eligible participant elects to exchange an eligible option, then all of the shares subject to such eligible option must be exchanged pursuant to the option exchange. If an eligible participant holds more than one eligible option grant, however, the eligible participant may choose, on a grant-by-grant basis, to exchange one or more eligible option grants without having to exchange all of his

22



or her eligible option grants.

Exchange Ratios.The option exchange is not structured as a one-for-one exchange. Instead, it will more closely approximate a value-for-value exchange of the eligible options for new replacement options. Eligible participants surrendering eligible options will receive new replacement options covering a lesser number of shares than are covered by the surrendered eligible options. The number of shares underlying an eligible option to be surrendered in the exchange for the right to receive a replacement option covering one share is referred to as the “exchange ratio.” The total number of replacement options an eligible participant will receive with respect to a surrendered eligible option will be determined on a grant-by-grant basis by dividing the number of shares underlying the surrendered eligible option by the applicable exchange ratio and rounding the result down to the nearest whole share. Stock options for fractional shares will not be issued. Since the exchange ratios will not be calculated until shortly before the commencement of the option exchange (at which time the fair value of the eligible options and replacement options can be estimated), we are unable to definitively determine at this time the number of new replacement options which may be granted in connection with the option exchange.

We have retained the services of Radford to determine the terms and exchange ratios appropriate to achieve our desired results. The exchange ratios for the option exchange will be based on the fair value of the eligible options (calculated using the Black-Scholes option pricing model). As a result, the exchange ratios are based on the valuation assumptions used in the Black-Scholes option pricing model, including the exercise price and the remaining term of the eligible options and the fair market value of our common stock on the assumed commencement date of the option exchange. Multiple tranches of options with similar fair values may be aggregated and exchanged based on a single exchange ratio. Setting the exchange ratios in this manner is intended to result in a fair value, for accounting purposes, of the replacement options that will be approximately equal to the fair value of the eligible options that are surrendered in the option exchange (based on valuation assumptions made when the option exchange commences). As a result, the exchange ratios will vary and generally will be higher as the exercise price of the eligible option increases. Our compensation committee will establish the final exchange ratios shortly before the option exchange commences based on Radford’s calculations and recommendations, updated as of the commencement of the option exchange, so that it will closely approximate a value-for-value exchange, but may adjust the exchange ratios prior to the commencement of the option exchange to the extent our compensation committee determines prior to the start of the option exchange that it is necessary or desirable to do so to assist in our retention goals of the option exchange or for other administrative reasons, such as rounding.

Although the exchange ratios cannot be determined now, we can provide an example if we make certain assumptions regarding the commencement date of the option exchange, the fair market value of our common stock and a sample methodology for determining the exchange ratios that would achieve our retention goals for the option exchange while striving to structure the option exchange as a value-for-value exchange. Radford used the Black-Scholes option pricing model to calculate the fair value of the eligible options that were used to develop the preliminary exchange ratio groupings shown in the table below. For illustration purposes, assuming a fair market value of our common stock of $10.25 for the valuation of the eligible options immediately prior to cancellation and for the valuation of the replacement options granted as a result of the option exchange, a $13.00 per share exercise price eligibility threshold, assuming a commencement date of April 30, 2016, grouping together eligible options with similar fair values and rounding the resulting ratios to the Radford recommended levels, the following exchange ratios would apply:

Exercise Prices of Eligible Options

$15.00 to $23.991.50 to 1
$24.00 to $29.991.50 to 1
$30.00 and Up2.00 to 1

Continuing this example, based on the assumptions described above, the following table summarizes information regarding the eligible options and the number of replacement options that may be issued with respect to such eligible options in the option exchange (assuming 100% participation), as of April 30, 2016.

The foregoing exchange ratios are provided merely as an example based on the assumptions described above. We will apply substantially the same methodology once these factors are decided closer to the time of commencement of the option exchange, subject to the potential adjustments described above. We expect the compensation committee’s determination of the final exchange ratios on the terms described above likely will result in some incremental compensation expense for financial accounting purposes. Our board of directors and compensation committee have determined that the recognition of some additional compensation cost may be necessary to achieve our retention goals of the option exchange and for administrative ease, which we believe will benefit the company and its stockholders in the long run.
Terms and Conditions of Replacement Options. Each replacement option will be evidenced by a stock option agreement between us and the eligible participant, and will be subject to the following additional terms and conditions:

Exercise Price of Replacement Options. All replacement options will be granted with an exercise price equal to the closing price of our common stock on the replacement option grant date as reported by the NASDAQ Global Select Market.

Vesting of Replacement Options. The replacement options will be completely unvested at the time of the new grant, regardless of whether the surrendered eligible options were partially or wholly vested. The replacement options will vest monthly as follows:

Replacement options granted in exchange for eligible option grants that are unvested or partially vested will vest monthly over three years following the replacement grant date; and

Replacement options granted in exchange for eligible option grants that are fully vested will vest monthly over two years following the replacement grant date.

The replacement options will vest only if the eligible participant remains an employee or consultant of the company or any of its wholly-owned subsidiaries through each respective vesting date. Replacement options that are unvested at the time of an eligible participant’s termination of service cannot be exercised and will be forfeited, unless otherwise provided by the administrator of the 2010 Plan.

Term of Replacement Options. The term of a stock option is the length of time during which it may be exercised. Under the option exchange, each replacement option will have a new term of ten years from the replacement grant date, subject to earlier expiration of the option upon the eligible participant’s termination of service.

Other Terms and Conditions of Replacement Options. The other terms and conditions of the replacement options will be governed by the terms and conditions of the 2010 Plan and the stock option agreements entered into thereunder. All replacement options will be non-qualified stock options granted under our 2010 Plan, regardless of the tax status of the eligible options surrendered for exchange.

Return of Eligible Options Surrendered; Effect on Plans. The eligible options surrendered for exchange will be cancelled and,

24



pursuant to the terms of the 2010 Plan, all shares of common stock that were subject to such surrendered eligible options that were originally granted under the 2010 Plan or 2006 Plan will automatically again become available for future awards under the 2010 Plan. These shares along with the shares currently available for grant under the 2010 Plan and the 2013 Plan will be used for grants of new hire and annual refresh awards, as permitted by the terms of such plans, to new and continuing employees, non-employee directors and consultants; however, as all future grants are within the discretion of the board of directors or the compensation committee, such grants are not currently determinable. Shares subject to eligible options originally granted under the 2013 Plan will be cancelled at the time of the option exchange and the shares subject to such surrendered options will not be available for future issuance under the 2013 Plan.
As of April 30, 2016, options to purchase 1,238,052 shares of common stock would be eligible options under the proposed option exchange based on the assumptions described above. Assuming all of the 1,238,052 eligible options are surrendered and cancelled pursuant to the option exchange and 859,140 new replacement options are granted in accordance with the applicable exchange ratios, the net effect is that the number of shares subject to outstanding options under the Plans would be reduced by 378,912 shares. Please see the “Reasons for the Option Exchange” section above for further details regarding the approximate reduction in the number of shares underlying options outstanding assuming that 100% of eligible options are exchanged and new replacement options are issued in accordance with the exchange ratios set forth above and for a description of the effect of the option exchange on the shares available for issuance under the Plans. If all of the eligible options were exchanged in accordance with the option exchange, the number of shares of common stock remaining available for issuance for future grants under the 2010 Plan would increase from approximately 706,535 shares to approximately 984,135 shares, excluding any possible future increases to the share reserve under the evergreen provision of the 2010 Plan.

Cash Payments.In certain limited cases where we have determined that offering replacement options would provide minimal retentive value, would be overly burdensome to implement or administer or would not provide a meaningful benefit to holders of eligible options, we will provide for a cash payment in exchange for surrendered eligible options. The amount of the cash payment will be calculated similar to the stock option exchange ratio and in a manner intended to provide those receiving cash payments with approximately the same fair value as their surrendered eligible options, less any taxes and social insurance contributions due on the payments. The cash payments will not be subject to any vesting schedule and will be made on the date that replacement options are granted.

Implementing the Option Exchange

We have not commenced the option exchange and will not do so unless our stockholders approve this proposal to permit the option exchange. Our board of directors authorized the option exchange on May 13, 2016, subject to stockholder approval. If this proposal is approved, our board or directors or compensation committee will determine the date upon which the option exchange will begin, which date will be within 12 months of the date of stockholder approval of this proposal. It is currently anticipated that the option exchange will commence during the third quarter of 2016.

Upon the commencement of the option exchange, eligible participants will be offered the opportunity to participate in the option exchange pursuant to a written offer that will be distributed to all eligible participants. Eligible participants will be given at least 20 U.S. business days in which to accept the offer of the replacement options in exchange for the surrender of their eligible options. After the option exchange is closed, the eligible options that were surrendered in the option exchange would be cancelled and the replacement options will be granted under the 2010 Plan on the date of cancellation of the surrendered eligible options. In those limited cases where cash payments are made in exchange for surrendered eligible options, such payments also will be made on the date of the cancellation of the surrendered eligible options. The shares of our common stock subject to surrendered eligible options that were originally granted under the 2010 Plan or the 2006 Plan will become available for future issuance under our 2010 Plan pursuant to its terms once the surrendered eligible options are cancelled. Shares subject to eligible options originally granted under the 2013 Plan will be cancelled at the time of the option exchange and the shares subject to such surrendered options will not be available for future issuance under the 2013 Plan.

Prior to commencement of the option exchange, we will file the offer to exchange with the Securities and Exchange Commission as part of a tender offer statement on Schedule TO. Eligible participants, as well as stockholders and members of the public, will be able to review the offer to exchange and other related documents filed by us with the Securitiestables and Exchange Commission free of charge on the Securities and Exchange Commission’s website at www.sec.gov.

U.S. Federal Income Tax Consequences

The following is a summary of the anticipated material U.S. federal income tax consequences of participating in the option exchange. A more detailed summary of the applicable tax considerations to participating holders will be provided in the offer to exchange. The option exchange should be treated as a non-taxable exchange for U.S. federal income tax purposes, and we and the eligible participants should recognize no income for U.S. federal income tax purposes upon the issuance of the replacement options. Recipients of any cash payments will recognize ordinary income for U.S. federal income tax purposes on the date the cash payments

25



are made to them, and the payments will be subject to applicable tax withholdings. The tax consequences for non-U.S. eligible participants may differ from the U.S. federal income tax consequences described in the preceding sentence. The tax consequences of the option exchange in foreign jurisdictions will depend on applicable foreign tax rules and regulations and will be fully disclosed to participants subject to the tax laws of foreign jurisdictions as part of the offer to exchange options.

Accounting Impact

We account for share-based payments in accordance with ASC 718. Under ASC 718, to the extent the fair value of each award of replacement options granted pursuant to the option exchange exceeds the fair value of the surrendered eligible options, such excess is considered incremental compensation. This excess, in addition to any remaining unrecognized expense for the eligible options surrendered in exchange for the new replacement options, will be recognized by us as an expense for compensation. This expense will be recognized ratably over the vesting period of the new replacement options in accordance with the requirements of ASC 718. In the event that any of the new replacement options are forfeited prior to their vesting due to termination of an eligible participant’s service, the compensation cost related to the forfeited options will not be recognized. We will establish the exchange ratios for the option exchange in a manner intended to result in the issuance of new replacement options that have a fair value approximately equal to the fair value of the exchanged options they replace, but with the ability to establish exchange ratios that result in some additional compensation expense to the extent our compensation committee determines prior to the start of the option exchange that it is necessary or desirable to do so to assist in our retention goals of the option exchange or for other administrative reasons, such as rounding. Additionally, compensation expense may be affected by fluctuations in our stock price after the exchange ratios have been set (which will occur shortly before the option exchange begins) but before the option exchange actually occurs. We do not, however, expect to recognize more than $200,000 in incremental compensation expense as a result of the option exchange. We currently recognize and will continue to recognize compensation expense relating to the eligible options, even though they are underwater and do not fully provide the intended incentive and retention benefits.

Potential Modification to Terms to Comply with Governmental Requirements or Changing Circumstances

The terms of the option exchange will be described in a tender offer document that will be filed with the Securities and Exchange Commission. Although we do not anticipate that the Securities and Exchange Commission would require us to modify the terms materially, it is possible that we will need to alter the terms of the option exchange to comply with potential Securities and Exchange Commission comments. In addition, it is currently our intention to make the program available to our eligible participants, including eligible participants of our wholly-owned subsidiaries who are located outside of the United States, where permitted by local law and where we determine it is feasible and practical to do so. It is possible that we will make modifications to the terms offered to eligible participants in countries outside the United States to comply with local requirements, or for tax or accounting reasons.

In addition, while the terms of the option exchange are expected to be materially similar to the terms described in this proposal, our board of directors or compensation committee may find it necessary or appropriate to change the terms of the option exchange to take into account legal requirements, accounting rules or corporate transactions involving the company (including, for instance, a merger or acquisition). The board of directors or the compensation committee reserves the right to amend, postpone or cancel the option exchange once it has commenced. Additionally, we may decide not to implement the option exchange even if our stockholders approve the option exchange. If our stock price increases significantly, we may reassess the advisability of implementing the option exchange.

Benefits of the Option Exchange to Eligible Participants

Because the decision whether to participate in the option exchange is completely voluntary, we are not able to predict who will participate, how many eligible options any particular group of eligible participants will elect to exchange, or the number of replacement options that we may grant. The option exchange will not be conditioned on a minimum level of participation. As
noted above, our Chief Executive Officer, members of our board of directors and former employees and consultants will not be eligible to participate in the option exchange. Because we cannot predict which or how many eligible participants will elect to participate in the option exchange, and which or how many eligible options such eligible participants will elect to exchange, future benefits pursuant to the option exchange are not currently determinable.

Effect on Stockholders

The option exchange was designed to provide renewed incentives and motivate the eligible participants to continue to create stockholder value and to reduce the number of shares currently subject to outstanding options, thereby avoiding the dilution in ownership that normally results from supplemental grants of replacement options or other awards. We are unable to predict the precise impact of the option exchange on our stockholders because we cannot predict which or how many eligible participants will elect to participate in the option exchange, and which or how many eligible options such eligible participants will elect to exchange. Please see the “Reasons for the Option Exchange” section above for the approximate reduction in the number of shares underlying options

PROPOSAL 3 TO APPROVE THE OPTION EXCHANGE. PROXIES SOLICITED BY 4:
APPROVAL OF AMENDMENT AND RESTATEMENT OF
EMPLOYEE STOCK PURCHASE PLAN
Introduction
Our stockholders are being asked to approve an amendment and restatement of our Employee Stock Purchase Plan (the “Existing ESPP”). The proposed amended and restated plan is referred to herein as the “Restated ESPP.” Our board of directors approved the Restated ESPP on April 14, 2020, subject to stockholder approval. The Restated ESPP will become effective upon stockholder approval.
The Restated ESPP is being submitted for stockholder approval in order to ensure that the Section 423 Component of the Restated ESPP (as described below) meets the requirements of Section 423 of the Internal Revenue Code (the “Code”). If the Restated ESPP is not approved by our stockholders, the Restated ESPP will not become effective, the Existing ESPP will continue in full force and effect, and we may continue to grant awards under the Existing ESPP, subject to its terms, conditions and limitations, using the shares available for issuance thereunder.
Overview of Proposed Amendments
Increase in Share Reserve; Elimination of Evergreen Provision. We strongly believe that an employee stock purchase program is a necessary and important incentive and retention tool. The Existing ESPP was first adopted by our board of directors and approved by our stockholders in 2010 in connection with our initial public offering. As of March 31, 2020, a total of 375,000 shares of our common stock were reserved under the Existing ESPP and a total of 49,597 shares of common stock remained available under the Existing ESPP for future issuance. The Existing ESPP contained an evergreen provision that provided for an annual increase in the number of shares available for issuance under the Existing ESPP on January 1 of each year during the ten year term of the Existing ESPP, beginning on January 1, 2011, equal to the least of 1% of our outstanding capital stock on the first day of the applicable fiscal year, or 31,250 shares (or a lesser amount determined by our board of directors). The automatic increases pursuant to the evergreen provision of the Existing ESPP since 2011 and through and including January 1, 2020 were 31,250 shares each, and these increases are included in the current share reserve under the Existing ESPP set forth above.
An additional 500,000 shares will be reserved for issuance under the Restated ESPP over the current share reserve under the Existing ESPP, all of which may be issued under the Section 423 Component or the Non-Section 423 Component (each as further described below). The evergreen provision under the Existing ESPP terminated with the final increase on January 1, 2020, and the Restated ESPP will not include an evergreen provision.
All of the foregoing share numbers may be adjusted for changes in our capitalization and certain corporate transactions, as described below under the heading “Adjustments.”
Removal of Fixed Term. The Existing ESPP will expire in October 2020. The Restated ESPP will not have a fixed term and will continue until terminated by our board of directors or the share reserve thereunder is exhausted.
Addition of Non-Section 423 Component. The Restated ESPP will have two components in order to give us increased flexibility in the granting of purchase rights under the Restated ESPP to U.S. and to non-U.S. employees. Specifically, the Restated ESPP authorizes the grant of options that are intended to qualify for favorable U.S. federal tax treatment (the “Section 423 Component”) under Section 423 of the Code. To facilitate participation for employees located outside of the U.S. in light of non-U.S. law and other considerations, the Restated ESPP also provides for the grant of options that are not intended to be tax-qualified under Code Section 423 (the “Non-Section 423 Component”). The plan administrator will designate offerings made under the Non-Section 423 Component and, except as otherwise noted below or provided in the Restated ESPP, we expect that the Section 423 Component and the Non-Section 423 Component generally will be operated and administered in the same way.
The Restated ESPP is not being amended in any material respect other than to reflect the changes described above.
Determination to Approve Restated ESPP
The table below presents information about the number of shares that were subject to outstanding equity awards under our equity incentive plans and the shares remaining available for issuance under those plans, each at March 31, 2020, and the proposed increase in shares authorized for issuance under the Restated ESPP.
The Existing ESPP and our 2010 Equity Incentive Award Plan (the “2010 Plan”) are the only equity incentive plans we currently have in place pursuant to which awards may still be granted. Two of our named executive officers still hold outstanding stock options and restricted stock units granted under our 2006 Equity Incentive Plan and our Employment Inducement Equity Incentive Award Plan, but no additional awards may be granted under those plans.

In determining whether to approve the Restated ESPP, our board of directors considered that:
Unless the Restated ESPP is authorized and approved by our stockholders, we will lose a powerful incentive and retention tool for employees that benefits all of our stockholders. We expect the share reserve increase under the Existing ESPP, prior to the increase included in the Restated ESPP, may be insufficient for the next scheduled offering period. The increase will enable us to continue our policy of equity ownership by employees as an incentive to contribute to our success.
Based on the three-year historical average share usage under the Existing ESPP described below, we expect the proposed aggregate share reserve under the Restated ESPP will be sufficient for the next several years of purchases, assuming employee participation in the Restated ESPP is consistent with historical levels, and further dependent on the changes in our stock price and future hiring activity, which we cannot predict with any degree of certainty at this time. The share reserve under the Restated ESPP could last for a shorter or longer time.
In setting the size of the share reserve under the Restated ESPP, as described above, our board of directors also considered the historical amounts of equity awards granted by our company in the past three years. In 2017, 2018 and 2019, equity awards representing a total of approximately 1,172,000 shares, 1,068,000 shares, and 1,510,000 shares, respectively, were granted under all of our equity plans, for an annual equity burn rate of 3.4%, 2.5% and 3.3%, respectively. This level of equity awards represents a 3-year average burn rate of 3.1% of common shares outstanding. Equity burn rate is calculated by dividing the number of shares subject to equity awards granted during the fiscal year (including shares issued under the Existing ESPP) by the number of common shares outstanding at the end of the fiscal year. In 2017, 2018 and 2019, share purchases representing 35,934 shares, 32,679 shares, and 28,146 shares, respectively, were issued under our Existing ESPP, which issuances represent an annual burn rate of 0.1% for all three years, solely with respect to the Existing ESPP.
In 2017, 2018 and 2019, our end of year overhang rate was 13.0%, 13.6% and 21.2%, respectively. If the Restated ESPP is approved, we expect our overhang at the end of 2020 will be approximately 16%. Overhang is calculated by dividing (1) the sum of the number of shares subject to equity awards outstanding at the end of the fiscal year plus shares remaining available for future award grants at the end of the fiscal year by (2) the number of common shares outstanding at the end of the fiscal year.
18


In light of the factors described above, and the fact that the ability to continue to grant equity compensation is vital to our ability to continue to attract and retain employees in the extremely competitive labor markets in which we compete, our board of directors has determined that the size of the share reserve under the Restated ESPP is reasonable and appropriate at this time. Our board of directors will not create a subcommittee to evaluate the risk and benefits for issuing shares under the Restated ESPP.
Summary of the Restated ESPP
The principal features of the Restated ESPP are summarized below, but the summary is qualified in its entirety by reference to the Restated ESPP itself, which is attached as Appendix A to this proxy statement.
Purpose
The purpose of the Restated ESPP is to assist our eligible employees in acquiring a stock ownership interest in our company and to help our eligible employees provide for their future security and to encourage them to remain in our employment.
Securities Subject to the Restated ESPP
A total of 875,000 shares of our common stock are authorized for issuance under the Restated ESPP (after taking into account the increase of 500,000 shares added to the existing share reserve under the Existing ESPP in connection with this amendment and restatement). All of the foregoing share numbers may be adjusted for changes in our capitalization and certain corporate transactions, as described below under the heading “Adjustments.”
Administration
Our board of directors administers the Restated ESPP and has the final power to construe and interpret both the Restated ESPP and the rights granted under it. Our board of directors has delegated administration of the Restated ESPP to our compensation committee. Our board of directors or compensation committee (the “plan administrator”) has the power, subject to the provisions of the Restated ESPP, to determine when and how rights to purchase shares of common stock will be granted and the provisions of each offering of such rights. For purposes of the Restated ESPP, the plan administrator may designate separate offerings under the Restated ESPP, the terms of which need not be identical, in which eligible employees of one or more designated subsidiaries will participate, even if the dates of the applicable offering periods in each such offering are identical, provided, however, that all participants granted purchase rights in an offering which are intended to comply with Section 423 of the Code will have the same rights and privileges within the meaning of Section 423 of the Code. In addition, the plan administrator have the power to settle all controversies regarding the Restated ESPP and purchase rights granted under it.
The plan administrator may adopt sub-plans, appendices, rules and procedures relating to the operation and administration of the Restated ESPP to facilitate participation in the Restated ESPP by employees who are foreign nationals or employed outside the U.S. To the extent any sub-plan or appendix is inconsistent with the requirements of Section 423 of the Code, it will be considered part of the Non-Section 423 Component. The provisions of the Restated ESPP will govern any sub-plan unless superseded by the terms of such sub-plan.
Eligibility
Only employees of Zogenix, Inc. (or any of its subsidiaries designated by the plan administrator) may participate in the Restated ESPP. Only employees of majority-owned subsidiary corporations (within the meaning of Section 423 of the Code) may participate in the Section 423 Component. The plan administrator has the authority to limit participation to those individuals who have been customarily employed more than 20 hours per week and more than five months per calendar year on the first day of an offering. In addition, the plan administrator may require that each employee has been continuously employed for such period preceding the grant as the plan administrator may require, but in no event will the required period of continuous employment be greater than two years. Finally, the plan administrator also has the power to exclude our officers who are “highly compensated” as defined in the Code. No employee is eligible to participate in the Restated 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 stock of Zogenix, Inc. or any of its parent or subsidiary corporations. Participation in the Section 423 Component is further subject to the eligibility requirements of Section 423 of the Code.
If the grant of a purchase right under the Restated ESPP to any employee of a designated subsidiary who is a citizen or resident of a foreign jurisdiction would be prohibited under the laws of such foreign jurisdiction or the grant of a purchase right to such employee in compliance with the laws of such foreign jurisdiction would cause the Restated ESPP to violate the requirements of Section 423 of the Code, as determined by the plan administrator in its sole discretion, such employee will not be permitted to participate in the Section 423 Component of the Restated ESPP. In addition, with respect to the Non-Section 423 Component, all of the foregoing rules will apply in determining who is an eligible employee, except the plan administrator may limit eligibility further within a participating company so as to only designate some employees of a participating company as eligible employees, and to the extent the foregoing eligibility rules are not consistent with applicable local laws.
19


Eligible employees become participants in the Restated ESPP by enrolling and authorizing payroll deductions by the deadline established by the plan administrator prior to the relevant offering date. Directors who are not employees are not eligible to participate. Employees who choose not to participate, or are not eligible to participate at the start of an offering period but who become eligible thereafter, may enroll in any subsequent offering period.
As of December 1, 2019 (the last enrollment date under the Existing ESPP), there were 140 employees who were eligible to participate in the Existing ESPP and who would have been eligible to participate in the Restated ESPP if it had been in effect on such date and had the subsidiaries for whom such employees work been designated as designated subsidiaries under the Restated ESPP as of such date, 89 of whom had elected to participate.
Participation in an Offering
Offering Periods and Purchase Periods. The Restated ESPP is implemented by offerings of rights to all eligible employees from time to time. Under applicable law and the terms of the Restated ESPP, the maximum length for an offering period under the Restated ESPP is 27 months. Each offering period consists of one or more purchase dates as determined by the plan administrator. Pursuant to the terms of our current offering periods under the Restated ESPP, a new offering period will automatically begin on each June 1 and December 1 over the term of the Restated ESPP and will be 12 months in duration. Each new offering period shall consist of two purchase periods of six months in length ending on May 31 and November 30 each year, with purchases occurring on the last trading day of a purchase period. If the fair market value of a share of our common stock on the first day of a later offering period is less than or equal to the fair market value on the start date of an ongoing offering period, then such ongoing offering period will terminate immediately following the purchase of shares on the purchase date and the participants in the terminated offering period will automatically be enrolled in the new offering period. The Restated ESPP allows for concurrent offerings, but an eligible employee may enroll in only one offering at a time.
Enrollment in the Restated ESPP. Eligible employees enroll in the Restated ESPP by delivering to us an agreement authorizing payroll deductions in an amount up to the maximum amount approved by the plan administrator. Pursuant to the Restated ESPP, such payroll deductions will be limited to up to 20% of an employee’s eligible cash compensation during the offering. A participant may increase or decrease his or her participation level at any time with such change to be effective commencing as of the next offering period. A participant may also increase or decrease his or her participation level to be effective in a subsequent purchase period of an ongoing offering in accordance with procedures established by us. A participant may decrease, but not increase, his or her participation level during a purchase period. The plan administrator may determine in its sole discretion at any time, including at any time following the commencement of an offering period or purchase period, that it will no longer accept participant requests to increase participation levels during such offering period or purchase period, as applicable. All payroll deductions made for a participant are credited to the participant’s account under the Restated ESPP and are included with the general funds of the Company, unless otherwise required by applicable law. Funds received upon sales of stock under the Restated ESPP are used for general corporate purposes. In general, no interest will be paid on participant accounts. With respect to the Non-Section 423 Component, interest may apply to participant accounts to the extent required by applicable law and approved by the plan administrator. In non-U.S. jurisdictions where participation in the Restated ESPP through payroll deductions is prohibited, the plan administrator may provide that an eligible employee may elect to participate through contributions to the participant’s account under the Restated ESPP in a form acceptable to the administrator in lieu of or in addition to payroll deduction.
Purchase Price. Unless otherwise determined by the plan administrator, the purchase price of the shares will be 85% of the lower of the fair market value of our common stock on the first day of the offering period or on the applicable purchase date (provided that the purchase price will not be less than 85% of the lower of the fair market value of our common stock on the first day of the offering period or on the applicable purchase date). The fair market value per share of our common stock under the Restated ESPP is generally the closing sale price of our common stock on the Nasdaq Stock Market on the date for which fair market value is being determined, or if there is no closing sales price for a share of our common stock on the date in question, the closing sales price for a share of common stock on the last preceding date for which such quotation exists. The closing price per share of our common stock on the Nasdaq Stock Market on March 31, 2020, was $24.73.
Purchase of Stock.In connection with offerings made under the Restated ESPP, the plan administrator may specify from time to time a maximum number of shares of common stock an employee may be granted the right to purchase and the maximum aggregate number of shares of common stock that may be purchased pursuant to such offering by all participants. In addition, no employee may purchase more than $25,000 worth of common stock (determined at the fair market value of the shares at the time such rights are granted) under all employee stock purchase plans (intended to qualify as such under Section 423(b) of the Code) of our company and its parent and subsidiary corporations for each calendar year in which the purchase rights are outstanding at any time. Pursuant to the Restated ESPP, the maximum number of shares that may be purchased by any single participant during any offering period or on any given purchase date is 5,000 shares. If the aggregate number of shares to be purchased upon exercise of all outstanding purchase rights would exceed the foregoing limits, the plan administrator may make a uniform and equitable allocation of available shares.
Participation in and Withdrawal from the Restated ESPP. Enrolled employees will automatically participate in subsequent offerings, provided the participant has not withdrawn from the Restated ESPP, continues to meet the eligibility requirements, and has not terminated employment with us. A participant may withdraw from a given offering without affecting his or her eligibility to
20


participate in future offerings under the Restated ESPP. Upon any withdrawal from an offering by the participant, we will distribute to the participant his or her accumulated payroll deductions without interest, less any accumulated deductions previously applied to the purchase of shares of common stock on the participant’s behalf during such offering, and such employee’s rights in the offering will be automatically terminated.
Termination of Employment. Unless otherwise specified by the plan administrator, a participant’s rights under any offering under the Restated ESPP terminate immediately upon cessation of an employee’s employment for any reason (subject to any post-employment participation period required by law), and we will distribute to such employee all of his or her accumulated payroll deductions, without interest.
Adjustments
In the event of any dividend or other distribution, change in control, reorganization, merger, amalgamation, consolidation, combination, repurchase, recapitalization, liquidation, dissolution, sale of securities, or other similar corporate transaction or event, affects our common stock such that an adjustment is determined to be appropriate in order to prevent dilution or enlargement of benefits under the Restated ESPP, the plan administrator shall make equitable adjustments, if any, to reflect such changes in the number of shares reserved under the Restated ESPP, the per offering period and per purchase period share limits and the price per share and number of shares of our common stock covered by each outstanding right . Such adjustments will be made by the plan administrator of the Restated ESPP, whose determination in that respect will be final, binding and conclusive (provided that no adjustment will be permitted if it would cause the Section 423 Component to fail to satisfy the requirements of Section 423 of the Code).
In the event of certain significant transactions or a change in control (as defined in the Restated ESPP), the administrator of the Restated ESPP may provide for (1) either the replacement or termination of outstanding rights in exchange for cash, (2) the assumption or substitution of outstanding rights by the successor or survivor corporation or parent or subsidiary thereof, if any, (3) the adjustment in the number and type of shares of stock subject to outstanding rights, (4) the use of participants’ accumulated payroll deductions to purchase stock on a new purchase date prior to the next purchase date and termination of any rights under ongoing offering periods or (5) the termination of all outstanding rights. Under the Restated ESPP, a change in control has the same definition as given to such term in the Existing ESPP.
Transferability. A participant may not transfer rights granted under the Restated ESPP other than by will, the laws of descent and distribution.
Amendment and Termination. The plan administrator of the Restated ESPP may amend, suspend or terminate the Restated ESPP. However, stockholder approval of any amendment to the Restated ESPP will be obtained for any amendment which changes the aggregate number or type of shares that may be sold pursuant to rights under the Restated ESPP, changes the corporations or classes of corporations whose employees are eligible to participate in the Restated ESPP, changes the Restated ESPP in any manner that would cause the Section 423 Component of the Restated ESPP to no longer be an employee stock purchase plan within the meaning of Section 423(b) of the Code, or is required under applicable law or stock exchange rules. The Restated ESPP will continue in effect until terminated by our board of directors or the share reserve is exhausted.
Federal Income Tax Consequences Associated with the Restated ESPP
The material federal income tax consequences of the Restated ESPP under current U.S. federal income tax law are summarized in the following discussion, which deals with the general tax principles applicable to the Restated ESPP. The following discussion is based upon laws, regulations, rulings and decisions now in effect, all of which are subject to change. Foreign, state and local tax laws, and employment, estate and gift tax considerations are not discussed due to the fact that they may vary depending on individual circumstances and from locality to locality.
As described above, the Restated ESPP has a Section 423 Component and a Non-Section 423 Component. The tax consequences for a U.S. taxpayer will depend on whether he or she participates in the Section 423 Component or the Non-Section 423 Component.
Tax Consequences to U.S. Participants in the Section 423 Component. The Section 423 Component of the Restated ESPP, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Section 423 of the Code. Under the applicable Code provisions, no income will be taxable to a participant until the sale or other disposition of the shares purchased under the Section 423 Component of the Restated ESPP. This means that an eligible employee will not recognize taxable income on the date the employee is granted an option under the Section 423 Component of the Restated ESPP (i.e., the first day of the offering period). In addition, the employee will not recognize taxable income upon the purchase of shares. Upon such sale or disposition, the participant will generally be subject to tax in an amount that depends upon the length of time such shares are held by the participant prior to disposing of them. If the shares are sold or disposed of more than two years from the first day of the offering period during which the shares were purchased and more than one year from the date of purchase, or if the participant dies while holding the shares, the participant (or his or her estate) will recognize ordinary income measured as the lesser of (1) the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price or (2) an amount equal to the applicable discount from the fair market value of the shares as of the date of grant. Any additional gain will be treated as long-term capital gain. If the shares are held
21


for the holding periods described above but are sold for a price that is less than the purchase price, there is no ordinary income and the participating employee has a long-term capital loss for the difference between the sale price and the purchase price.
If the shares are sold or otherwise disposed of before the expiration of the holding periods described above, the participant will recognize ordinary income generally measured as the excess of the fair market value of the shares on the date the shares are purchased over the purchase price and we will be entitled to a tax deduction for compensation expense in the amount of ordinary income recognized by the employee. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on how long the shares were held following the date they were purchased by the participant prior to disposing of them. If the shares are sold or otherwise disposed of before the expiration of the holding periods described above but are sold for a price that is less than the purchase price, the participant will recognize ordinary income equal to the excess of the fair market value of the shares on the date of purchase over the purchase price (and we will be entitled to a corresponding deduction), but the participant generally will be able to report a capital loss equal to the difference between the sales price of the shares and the fair market value of the shares on the date of purchase.
We are not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary income recognized upon a sale or disposition of shares prior to the expiration of the holding periods described above.
Tax Consequences to U.S. Participants in the Non-Section 423 Component. A U.S. participant in the Non-Section 423 Component will recognize ordinary income equal to the fair market value of the shares on the date the shares are purchased over the purchase price.
When the participant sells the shares he or she purchased under the Non-Section 423 Component of the Restated ESPP, he or she also will have a capital gain or loss equal to the difference between the sales proceeds and the fair market value of the shares on the date of purchase. This capital gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on how long the shares were held following the date they were purchased by the participant prior to disposing of them.
Any compensation income that the participant receives upon the purchase of shares of common stock under the Non-Section 423 Component of the Restated ESPP is subject to applicable tax withholding. In addition, the compensation income is required to be reported as ordinary income to the participant on his or her annual Form W-2, and the participant is responsible for ensuring that this income is reported on his or her individual income tax return.
With respect to U.S. participants, we will generally be entitled to a deduction for amounts taxed as ordinary income to a participant to the extent of ordinary income recognized upon a purchase made under the Non-Section 423 Component.
New Plan Benefits
Because the number of shares that may be purchased under the Restated ESPP will depend on each employee’s voluntary election to participate and on the fair market value of our common stock at various future dates, the actual number of shares that may be purchased by any individual cannot be determined in advance.
Plan Benefits under the Existing ESPP

In addition, we explain how and why the compensation committee and our board of directors arrived at specific compensation policies and decisions involving our executive officers during the fiscal year ended December 31, 2015.

Executive Summary
We recognize that the ability to excel depends on the integrity, knowledge, imagination, skill, diversity and teamwork of our employees. To this end, the key objectives of our executive compensation program are:
To attract, engage and retain an executive team who will provide leadership for our future success by providing competitive total pay opportunities.
To establish a direct link between our business results, individual executive performance and total executive compensation.

To attract, engage and retain an executive team who will provide leadership for our future success by providing competitive total pay opportunities.
To establish a direct link between our business results, individual executive performance and total executive compensation.
To align the interests of our executive officers with those of our stockholders.
To align the interests of our executive officers with those of our stockholders.
The primary elements of our executive compensation program are (1) base salary, (2) annual short-term cash incentives, (3) long-term equity incentives, (4) post-termination benefits, and (5) other benefits, such as health insurance and retirement benefits. We believe that each component aligns the interests of our named executive officers with the interests of our stockholders in different ways, whether through focusing on short-term and long-term performance goals, promoting an ownership mentality toward one’s job, or linking individual performance to our performance.
In general, the majority of our named executive officers’ total compensation is tied directly to corporate and individual performance, increases in our stock price, or both. Specific elements of our executive compensation program that demonstrate our pay-for-performance philosophy include:
The performance measures in our short-term cash incentive program are linked to key corporate objectives.
Corporate achievement represents the majority of each named executive officer’s annual bonus opportunity.
The performance measures in our short-term cash incentive program are linked to key corporate objectives.
Corporate achievement represents the majority of each executive’s annual bonus opportunity.
Our long-term equity incentives are primarily granted in the form of stock options, which provide value to our executives only if our stock price increases.
Our long-term equity incentives are provided to named executive officers in the form of service-based equity awards, including a mix of stock options and restricted stock units (“RSUs”).
This mix of compensation is intended to ensure that total compensation reflects our overall success or failure and to motivate executive officers to meet appropriate performance measures. In determining each element of compensation for any given year, our board of directors and our compensation committee consider and determine each element individually and then review the resulting total compensation and determine whether it is reasonable and competitive. We do not have a pre-established policy or target for the allocation between either cash and non-cash or short-term and long-term incentive compensation.
We believe that the total compensation received by our named executive officers relating to 20152019 was appropriate when viewed in light of our corporate achievements during 20152019 and the individual performance of our named executive officers.
Compensation Determination Process
The compensation committee of our board of directors develops, reviews and approves each of the elements of our executive compensation program. The compensation committee also regularly assesses the effectiveness and competitiveness of our compensation programs.
In the first quarter of each year, the compensation committee reviews the performance of each of our named executive officers during the previous year. At this time the compensation committee also reviews our performance relative to the corporate performance objectives set by the board of directors for the year under review and makes the final bonus payment determinations based on our overall corporate performance and, with respect to the named executive officers other than our Chief Executive Officer, the compensation committee’s evaluation of each named executive officer’s performance for the year under review. In connection with this review, the compensation committee also reviews and adjusts, as appropriate, annual base salaries for our named executive officers and grants, as appropriate, additional stock optionequity awards to our named executive officers and certain other eligible employees for the then-current fiscal year.employees.
During the fourth quarter of each year our compensation committee also reviews the corporate performance objectives for purposes of our performance bonus programs for the following year, but such objectives historically have been recommended to the full board of directors for approval.

of all of our named executive officers, other than himself. The compensation committee also, on occasion, meets with our Chief Executive Officer to obtain recommendations with respect to our compensation programs and practices generally. The compensation
committee considers, but is not bound to accept, the Chief Executive Officer’s recommendations with respect to named executive officer compensation. In the beginning of each year, our named executive officers work with our Chief Executive Officer to establish their individual performance goals for the year, based on their respective roles within the company.
Our Chief Executive Officer generally attends all of the compensation committee meetings, but the compensation committee also holds executive sessions that are not attended by any members of management or non-independent directors, as needed from time to time. Any deliberations or decisions regarding our Chief Executive Officer’s compensation are made without him present.
Role of Compensation Consultant and Comparable Company Information
Our compensation committee has not historically established compensation levels based on benchmarking. Our compensation committee has instead relied upon the judgment of its members in making compensation decisions, after reviewing our overall corporate performance and carefully evaluating aconducting an in-depth, comprehensive evaluation of each named executive officer’s performance during the year against established goals, leadership qualities, operational performance, business responsibilities, career with our company, current compensation arrangements and long-term potential to enhance stockholder value.
The compensation committee is authorized to retain the services of third-party compensation consultants and other outside advisors, from time to time, asto assist in its evaluation of executive compensation, including the committee sees fit, in connection with compensation matters.

In 2019, the compensation committee will report directly to the compensation committee which has the authority to select, retain and terminate any such consultants or advisors.
In 2015, the compensation committee determined to engageagain retained Radford, as itsa business unit of AON plc (“Radford”), an independent compensation consultant to providethird-party compensation consulting services.firm for guidance in making compensation decisions. Specifically, for 2015,2019, the compensation committee requested Radford to advise it on a variety of compensation-related issues, including:
conducting market research and analysis of current practices of comparable public companies to assist the compensation committee in developing director and executive compensation levels;
reviewing our peer group to determine whether additional or different peer companies or groups are necessary to provide appropriate information on market practices and compensation levels;
compiling, analyzing and presenting third-party survey data regarding the compensation of executives at comparable companies;
advising with regard to the amendment and restatement of our equity plan during 2019; and
evaluating our current equity compensation program relative to our peer group, including equity ownership levels; and
providing general information concerning executive compensation trends and developments.
providing general information concerning director and executive compensation trends and developments.
Radford did not provide any other services to us in 20152019 beyond its engagement as an advisor to the compensation committee on director and executive compensation matters. After review, theThe compensation committee has determinedassessed the independence of Radford pursuant to SEC and Nasdaq rules and concluded that there is no conflict of interest resultingexisted that would have prevented Radford from retaining Radfordserving as an independent consultant to the compensation committee currently or during the year ended December 31, 2015. In reaching these conclusions, the compensation committee considered the factors set forth in Exchange Act Rule 10C-1.2019.
For 2015,2019, Radford assisted the compensation committee in confirming aidentifying an appropriate peer group of companies to be used in the compensation setting process. For 2015,for use as a reference when determining 2019 director and executive compensation. The identified peer group consisted of 2324 life sciences companies in similar phases of development as us with the following characteristics was selected based on the following parameters and not on the basis of executive compensation levels:
Market capitalization less than $6.0 billion, with a 30-day average market capitalization being $2.119 billion as of October 28, 2018, when the peer group was first approved by the compensation committee for 2019 compensation purposes. Zogenix had a 30-day average market capitalization of $1.787 billion as of such date, and ranked in the 46th percentile relative to the peer group on this metric;
Annual revenue of less than $100.0 million, with the average trailing twelve months revenue as of October 28, 2018 being $26.4 million. Zogenix did not generate any revenue during the same period; and
Market capitalization less than $1.0 billion (average market capitalization of $547.9 million) (as of February 2, 2015);
Less than 600 employees, with an average of 173 employees as of December 31, 2017. Zogenix had 68 employees as of the same date and ranked in the 14th percentile relative to the peer group on this metric.
Annual revenues of less than $200.0 million; and

Less than 500 employees.

Although we maintain the peer group for executive compensation purposes, the peer group compensation data is limited to publicly available information and therefore does not necessarily provide comparisons for all officers by position as is offered by more comprehensive survey data, which has the advantage of including data on executive positions beyond what is available in public filings. In light of this, during 2015,2019, the compensation committee also reviewed data from The Radford Global Life Sciences Compensation Survey, which consists ofincluded compensation data for public companies throughout the United States primarily from the life sciences industry, with revenues under $200 million.600 employees and market capitalizations of between $500 million and $6 billion. With respect to the survey data presented to the compensation committee, the identities of the individual companies included in the survey were not provided to the compensation committee, and the compensation committee did not refer to individual compensation information for such companies. We believe that by utilizing both sets of survey data, which are weighted equally in determining the final comparable company information reviewed by our compensation committee, our compensation committee is able to review an appropriate set of competitive data for use in making compensation decisions. We believe that by utilizing both publicly available peer group data and the survey data from the published surveys, we are able to develop the best set of competitive data for use in making compensation decisions.
28


Our compensation committee reviewed the foregoing comparable company data in connection with its determinations of the 20152019 base salaries, target bonuses and equity awards for our named executive officers. However, our committee did not attempt to set our compensation levels or awards at a certain target percentile with respect to the comparable company data or otherwise rely entirely on that data to determine named executive officer compensation. Instead, as described above and consistent with past practice, the compensation committee members relied on their judgment and experience in setting those compensation levels and making those awards.
However, the compensation committee generally strives to set cash compensation and target cash compensation at or below the 50th percentile of the peer company data for comparable positions and total annual equity award value at approximately the 75th percentile, but variations on this pay positioning occur from year to year.
We expect that the compensation committee will continue to review comparable company data in connection with setting the compensation we offer our named executive officers to help ensure that our compensation programs are competitive and fair.
We strive to achieve an appropriate mix between equity incentive awards and cash payments in order to meet our objectives. Any apportionment goal is not applied rigidly and does not control our compensation decisions, and our compensation committee does not have any formal policies for allocating compensation between long-term and short-term compensation or cash and non-cash compensation.
The compensation levels of the named executive officers reflect to a significant degree the varying roles and responsibilities of such executives. As a result of the compensation committee’s and the board of director’s assessment of our Chief Executive Officer’s and President’s roles and responsibilities within our company, there are significant compensation differentials between these named executive officers and our other named executive officers.

34



We do not yet have a formal policy to adjust or recover awards or payments if the relevant performance measures upon which they are based are restated or are otherwise adjusted in a manner that would otherwise reduce the size of the initial payment or award.
Executive Compensation Components
The following describes each component of our executive compensation program, the rationale for each, and how compensation amounts are determined.
Base Salaries
In general, base salaries for our named executive officers are initially established through arm’s length negotiation at the time the executive is hired, taking into account such executive’s qualifications, experience and prior salary. Base salaries of our named executive officers are approved and reviewed annually by our compensation committee and adjustments to base salaries are based on the scope of an executive’s responsibilities, individual contribution, prior experience and sustained performance. Decisions regarding salary increases may take into account an executive officer’s current salary, equity ownership, and the amounts paid to an executive officer’s peers inside our company by conducting an internal analysis, which compares the pay of an executive officer to other members of the management team. Base salaries are also reviewed in the case of promotions or other significant changes in responsibility. Base salaries are not automatically increased if the compensation committee believes that other elements of the named executive officer’s compensation are more appropriate in light of our stated objectives. This strategy is consistent with our intent of offering compensation that is cost-effective, competitive and contingent on the achievement of performance objectives.
Our Chief Executive Officer’s base salary is based upon the same policies and criteria used for other named executive officers as described above. Each year the compensation committee reviews the Chief Executive Officer’s compensation arrangements and his individual performance for the previous fiscal year, as well as our overall corporate performance, as a whole, and makes recommendations to the full board of directors of adjustments to such compensation, if appropriate.
In March 2015,2019, the compensation committee reviewed the base salaries of our named executive officers. The compensation committee, in consultation with our Chief Executive Officer (with respect to the salaries of our other named executive officers) and its independent compensation consultant, determined that the base salaries of our named executive officers would be as follows, which increases were effective April 1, 2015:2019: Dr. Farr, $412,000; Ms. Rhoads, $360,500; and$585,000; Mr. Smith, $412,200; Dr. Galer, $360,500.$427,500; Dr. Farfel, $412,000; and Mr. Sagrolikar, $390,800. These increases represented an annual increase of approximately 3%, with the exception of Dr. Farr, whose annual increase was approximately 4%. Dr. Farr’s increase was higher as his 2018 base salary was significantly below the 50th percentile of similarly-situated executives and the compensation committee determined a larger increase was appropriate to bring him closer into line with the company's pay positioning philosophy. The 3% annual increase overfor the named executive officers’ 2014 salary levels, which wasofficers other than Dr. Farr were consistent with the merit-based salary increases for all of our employees generally. Upon his promotion to Chief Executive Officer in April 2015, Dr. Farr’s base salary was further increased to $450,000. Mr. Hawley did not receive a base salary increase in 2015.
Upon their hiring in July 2015, the compensation committee determined thatIn general, for 2019, the base salaries for Dr. Farfel and Dr. Darcis would be as follows: Dr. Farfel, $350,000; and Dr. Darcis £230,000.
of our named executive officers generally approximated the 25th percentile of similarly-situated executives among our peer group.
The actual base salaries paid to all of our named executive officers for 20152019 are set forth in the “Summary Compensation Table” below.
Performance Bonuses
Each named executive officer is also eligible for a performance bonus based upon the achievement of certain corporate performance goals and objectives approved by our board of directors and, with respect to our named executive officers other than Dr. Farr, individual performance.
29


Bonuses are set based on the executive’s base salary as of the end of the bonus year, and are expected to be paid out in the first quarter of the following year. The target levels for executive bonuses for 20152019 were as follows: 60% of base salary for theour President and Chief Executive Officer (100% of which is based on corporate objectives), 55% of base salary for our President (90% of which is based on corporate objectives and 10% of which is based on individual performance), and 45% of base salary for our Executive Vice President and Chief Financial Officer, Executive Vice President and Chief Medical Officer, Executive Vice President and Chief Development Officer and Executive Vice President and General Manager, Europeother named executive officers (90% of which is based on corporate objectives and 10% of which is based on individual performance). Dr. Farr’sIn general, the target bonus was increased to 60%bonuses of base salary upon his promotion to Chief Executive Officerour named executive officers approximate the 50th percentile of similarly-situated executives among our peer group, which generally results in April 2015.target total cash compensation for our named executives at approximately the 50th percentile of similarly-situated executives, although target total compensation for our named executives for 2019 fell below the 50th percentile across the board.
At the beginning of each year, the board of directors (considering the recommendations of the compensation committee and management) sets corporate goals and milestones for the year. These goals and milestones and the proportional emphasis placed on each are set by the board of directors after considering management input and our overall strategic objectives. These goals generally relate to factors such as financial targets, achievement of product development objectives and establishment of new collaborative arrangements. The board of directors, upon recommendation of the compensation committee, determines the level of achievement of the corporate goals for each year. The individual component of each named executive’s bonus award is not necessarily based on the

35



achievement of any predetermined criteria or guidelines but rather on the compensation committee’s subjective assessment of the officer’s overall performance of his or her duties. In coming to this determination, our compensation committee does not follow any guidelines, nor are there such standing guidelines regarding the exercise of such discretion.
All final bonus payments to our named executive officers are determined by our compensation committee. The actual bonuses awarded in any year, if any, may be more or less than the target, depending on individual performance and the achievement of corporate objectives and may also vary based on other factors at the discretion of the compensation committee (or the full board of directors, with respect to our Chief Executive Officer). Under our annual incentive plan, the maximum bonus payable to an executive is 125% of his or her target bonus.
20152019 Performance Bonuses. For 2015,2019, corporate objectives fell into the following fourthree categories: development and preparation for commercialization of ZX008 (50%Fintepla for Dravet syndrome (55%); readying our Relday programclinical development of Fintepla for potential strategic partnering (20%); contract work relating to Sumavel DosePro and Zohydro ER (15%Lennox-Gastaut syndrome (25%); and value realization from the sale of Zohydro ER (15%pipeline expansion (20%). Objectives were weighted based on their level of importance to theour business plan.
In evaluating management’s performance against our 20152019 corporate goals, our board of directorscompensation committee determined to award a corporate achievement level of 98%80% relative to those goals. Both qualitative and quantitative guidelines were established for purposes of evaluating performance relative to the corporate objectives during 2015.2019. These performance objectives were used as a guide by the board of directorscompensation committee in subjectively determining overall corporate performance as they represented those areas in which the named executive officers and our employees generally were expected to focus their efforts. The board of directorscompensation committee believed that it was better to evaluate our overall performance in these areas throughout the year in light of the general economic and industry conditions in which we operate. In coming to its final determination regarding the overall corporate achievement percentage, our board of directorscompensation committee awarded 97.5%61% credit for corporate performance relative to the first objective, noting that we submitted an Investigational New Drug Application for ZX008after taking into account the FDA refusal-to-file letter and developed a publication strategy and global commercialization plan, thoughsubsequent successful resubmission of the initiation of Phase 3 clinical studies was delayed.Fintepla new drug application in September 2019.

With respect to the third objective, our board of directorscompensation committee awarded 100%108% credit, noting that we met the contractual requirements to our partners with respect to both Sumavel DoseProcompany expanded its pipeline through the acquisition of Modis Therapeutics and Zohydro ER. With respect to the fourth objective, our board of directors awarded 100% credit, noting that significant value was realized due to the sale of the Zohydro ER business.MT1621. This overall 98%80% achievement level was then used to determine each named executive officer’s bonus. For the named executive officers other than Dr. Farr, each of his or her target bonus was split into its corporate and individual components, based on the weighting applicable to such named executive officer as described above.
The compensation committee’s determination of the individual components of the 20152019 bonus awards for our named executive officers was not based on the achievement of any predetermined individual performance objectives, criteria or guidelines, but rather on the compensation committee’s subjective assessment of each officer’s overall performance of their duties during 2015. The named executive officers2019. Dr. Galer and Mr. Sagrolikar each received a 100% individual achievement level.level, Dr. Farfel received an 80% individual achievement level and Mr. Hawley did not receive an annual bonus due to the fact that he resigned from his position as Chief Executive Officer in April 2015.Smith received a 125% achievement level.
The annual performance bonuses paid to our named executive officers for 20152019 are set forth in the “Summary Compensation Table” below.
Long-Term Equity Incentives
The goals of our long-term, equity-based incentive awards are to align the interests of our named executive officers and other employees, non-employee directors and consultants with the interests of our stockholders. Because vesting is based on continued employment, our equity-based incentives also encourage the retention of our named executive officers through the vesting period of the awards. In determining the size of the long-term equity incentives to be awarded to our named executive officers, we take into account a number of internal factors, such as the relative job scope, the value of existing long-term incentive awards, individual performance history, prior contributions to us and the size of prior grants. For 2015,2019, while our compensation committee reviewed competitive market data prepared by Radford in connection with its grant of long-term equity incentive awards to the named executive officers, such awards were not determined by reference to any specific target level of compensation or benchmarking. Based upon
30


these factors, the compensation committee determines the size of the long-term equity incentives at levels it considers appropriate to create a meaningful opportunity for reward predicated on the creation of long-term stockholder value. During 2015, we granted stock options to the named executive officers.
To reward and retain our named executive officers in a manner that best aligns employees’ interests with stockholders’ interests, we use stock options as the primary incentive vehicles for long-term compensation. We believe that stock options are an effective tool for meeting our compensation goal of increasing long-term stockholder value by tying the value of the stock options to our future performance. Because employees are able to profit from stock options only if our stock price increases relative to the stock option’s

36



exercise price, we believe stock options provide meaningful incentives to employees to achieve increases in the value of our stock over time.
We use stock options to compensate our named executive officers both in the form of initial grants in connection with the commencement of employment and annual refresher grants. Annual grants of options are typically approved by the compensation committee during the first quarter of each year. While we intend that the majority of stock option awards to our employees be made pursuant to initial grants or our annual grant program, the compensation committee retains discretion to make stock option awards to employees at other times, including in connection with the promotion of an employee, to reward an employee, for retention purposes or for other circumstances recommended by management or the compensation committee.
The exercise price of each stock option grant is the fair market value of our common stock on the grant date, as determined by our board of directors from time to time. Stock option awards granted in connection with an employee’s commencement of employment generally vest over a four-year period as follows: 25% of the shares underlying the option vest on the first anniversary of the date of the vesting commencement date and the remainder of the shares underlying the option vest in equal monthly installments over the remaining 36 months thereafter. Annual stock option awards to our named executive officers vest monthly over a four-year period. From time to time, our compensation committee may, however, determine that a different vesting schedule is appropriate. For
In 2019, the compensation committee granted service-based stock options and RSUs to our named executive officers, with the split between stock options and RSUs set at approximately 75% of the total equity award value in the form of stock options and 25% of the total equity award value in the form of RSUs. The RSUs were introduced as part of our long-term equity incentive program during 2017 to add an additional vehicle for use in our incentive and retention program and to tie a descriptionportion of certain accelerated vesting provisions applicableour named executive officers’ incentive compensation to such options, see “— Post Terminationour long-term performance.

We do not have any stock ownership requirements for our named executive officers.
In March 2015,2019, the compensation committee awarded the following63,750 stock options to each of our named executive officers (which give effect to the 1-for-8 reverse stock split of our common stock that occurred on July 1, 2015): Mr. Hawley, options to purchase 31,250 shares;(other than Dr. Farr). Dr. Farr options to purchase 31,250 shares; Ms. Rhoads, options to purchase 28,125 shares; and Dr. Galer, options to purchase 28,125 shares. In addition, in May 2015, the compensation committeewas awarded options to purchase 93,750 shares to Dr. Farr in connection with his promotion to Chief Executive Officer.160,000 stock options. Each of these option awards vests monthly over a four-year period.period from the date of grant.
In July 2015,Also in March 2019, the compensation committee awarded Dr. Farfel options8,125 RSUs to purchase 56,250 shares and Dr. Darcis options to purchase 50,000 shares. Eacheach of these option awards vest over a four-year period, with 25% of the options vesting on the first anniversary of the date of grant and the remainder vesting in equal monthly installments over the three years thereafter.
In October 2015, the compensation committee awarded the following options to our named executive officers: Ms. Rhoads, options to purchase 30,000 shares;officers (other than Dr. Galer, options to purchase 30,000 shares;Farr). Dr. Farfel, options to purchase 15,000 shares;Farr was awarded 20,000 RSUs. The RSUs vest in four equal annual installments on March 15, 2021, 2022, 2023 and Dr. Darcis, options to purchase 15,000 shares. One-half of the shares subject to each option award will vest monthly over a three-year period, and the remaining one-half of the shares subject to each option award will vest based on the following performance milestone: the U.S. Food and Drug Administration’s acceptance of our New Drug Application for ZX008 on or before the three-year anniversary of the date of grant.2024.
The compensation committee’s recommendation regarding each named executive officer’s award amount was not based on any quantifiable factors, but instead was based on the compensation committee’s subjective analysis of the award levels the committee deemed appropriate for each executive in light of various factors, including the dilution created as a result of our public offerings and the need to continue to incentivize our executives. Each of these factors was taken into consideration by the compensation committee for each executive, as was management’s recommendations regarding the appropriate award levels. The final award levels, however, were entirely based on the compensation committee’s subjective analysis of these general factors and internal pay equity considerations. In general, the target total value of the equity incentives granted to our named executive officers in 2019 approximated the 75th percentile of similarly-situated executives among our peer group.
For a description of thecertain accelerated vesting provisions applicable to the foregoing equitystock awards granted to our named executive officers, see “— Post Termination and Change in Control Benefits” and “— Employment Agreements” below.
We have had no program, plan or practice pertaining to the timing of stock option grants to named executive officers coinciding with the release of material non-public information.
Retirement Savings
All of our full-time employees in the United States, including our named executive officers, are eligible to participate in our 401(k) plan. Pursuant to our 401(k) plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit ($18,00019,000 in 2016)2019), with additional salary deferrals not to exceed $6,000 available to those employees 50 years of age or older, and to have the amount of this reduction contributed to our 401(k) plan. While we may electOur 401(k) Plan permits us to make discretionary matching contributions, no suchand in 2019 we made individually de minimis matching contributions have been made. For so long as we do not maintain any company-paid pension scheme in the United Kingdom and Dr. Darcis resides in the United Kingdom, Dr. Darcis receives a monthly stipend to purchase individually-obtained pension benefits in the United Kingdom.

for all plan participants, including our named executive officers.
Health and Welfare Benefits, Perquisites and Other Compensation
The establishment of competitive benefit packages for our employees is an important factor in attracting and retaining highly qualified personnel.
31


Health and Welfare Benefits. Our named executive officers other than Dr. Darcis are eligible to participate in all of our employee benefit plans, including our medical, dental, vision, group life and disability insurance plans, in each case on the same basis as other employees. We believe that these health and welfare benefits help ensure that we have a productive and focused workforce through reliable and competitive health and other benefits. For so long as we do not maintain any company-paid health plan in the United Kingdom and Dr. Darcis resides in the United Kingdom, Dr. Darcis receives a monthly stipend to purchase individually-obtained medical and life insurance in the United Kingdom.
Perquisites. We do not provide significant perquisites or personal benefits to our named executive officers. Dr. Darcis receives an annual car allowance.Pursuant to his employment agreement, Mr. Sagrolikar is entitled to relocation benefits in connection with his relocation to the San Francisco Bay Area, which is expected to occur in 2020.
Post Termination and Change in Control Benefits
We have entered into employment agreements which provide for certain severance benefits in the event a named executive officer’s employment is involuntarily or constructively terminated. Such severance benefits are intended and designed to alleviate the financial impact of an involuntary termination and maintain a stable work environment through salary continuation and equity award vesting acceleration. We provide severance benefits because they are essential to help us fulfill our objective of attracting and retaining key managerial talent. While these arrangements form an integral part of the total compensation provided to these individuals and are considered by the compensation committee when determining executive officer compensation, the decision to offer these benefits did not influence the compensation committee’s determinations concerning other direct compensation or benefit levels. The compensation committee has determined that such arrangements offer protection that is competitive within our industry and for our company size and are designed to attract highly qualified individuals and maintain their employment with us. In determining the severance benefits payable pursuant to the executive employment agreements, the compensation committee considered what level of severance benefits would be sufficient to retain our current executive team and to recruit talented executives in the future, which determination was based in part on input from management and our board of directors. For a description of these employment agreements, see “— Employment Agreements” below.
Prohibition on Certain Transactions in Zogenix Securities
Our insider trading policy prohibits officers, directors and employees, and entities controlled by such individuals and members of their households, from making short sales in our equity securities, transacting in puts, calls or other derivative securities involving our equity securities, on an exchange or in any other organized market, engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, purchasing our securities on margin or pledging our securities as collateral for a loan.
Response to 2014 Say on Pay2019 Say-on-Pay Vote
In May 2014,2019, we held a stockholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our stockholders overwhelmingly approved the compensation of our named executive officers, with over 98%93% of stockholder votes cast in favor of our 20142019 say-on-pay resolution (excluding abstentions and broker non-votes). As we evaluated our compensation practices and talent needs throughout 2015,2019, we were mindful of the strong support our stockholders expressed for our compensation philosophy. As a result, the compensation committee has decided to generally retain our existing approach to executive compensation for our continuing executives, with an emphasis on short- and long-term incentive compensation that rewards our senior executives for corporate and individual performance.
In addition, when determining how often to hold a stockholder advisory vote on executive compensation, the board of directors took into account the strong preference for a triennial vote expressed by our stockholders at our 2011 annual meeting. Accordingly, the board of directors determined that we will hold an advisory stockholder vote on the compensation of our named executive officers every three years until the next say-on-pay frequency vote.
Tax Deductibility of Executive Compensation
The compensation committee and our board of directors have considered the potential future effects of Section 162(m) of the Internal Revenue Code on the compensation paid to our executive officers. Section 162(m) disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1.0 million in any taxable year for our Chief Executive Officer“covered employees.” Prior to the Tax Cuts and eachJobs Act of 2017, covered employees generally consisted of a company’s chief executive officer and its three most highly compensated executive officers serving at the end of the othertaxable year (other than its chief financial officer), and compensation that qualified as “performance-based” under Section 162(m) was exempt from this $1 million deduction limitation. As part of the Tax Cuts and Jobs Act of 2017, the ability to rely on this exemption was, with certain limited exceptions, eliminated; in addition, the definition of covered employees was expanded to generally include all named executive officers (other than our Chief Financial Officer), unlessofficers. Although we historically maintained plans that were intended to permit the payment of deductible compensation under Section 162(m) of the Code if the requirements of Section 162(m) were satisfied, subject to the limited transition relief rules in the Tax Cuts and Jobs Act of 2017, we may no longer be able to take a deduction for any compensation in excess of $1 million that is performance based.paid to a covered employee. While we consider the tax deductibility of each element of executive compensation as a factor in our overall compensation program, the compensation committee, however, retains the discretion to approve compensation that may not qualify for the compensation deduction if, in light ofconsidering all applicable circumstances, it would be in our best interest for such compensation to be paid without regard to whether it may be tax deductible.

(1)The amounts shown in these columns constitute stock options and RSUs, as applicable, granted under our equity incentive programs. The amounts are valued based on the aggregate grant date fair value of the award in accordance with ASC 718. See Note 12 to our consolidated financial statements in our 2019 Annual Report on Form 10-K filed with the SEC on March 2, 2020 for a discussion of the relevant assumptions used in determining the grant date fair value of equity awards pursuant to ASC 718. These amounts do not reflect whether the recipient has actually realized or will realize a financial benefit from the awards (such as by exercising stock options). Whether, and to what extent, a named executive officer realizes a financial benefit from the awards will depend on our actual operating performance, stock price fluctuations and the named executive officer’s continued service to us.

For a discussion of the valuation assumptions, see Note 13 to our consolidated financial statements for the year ended December 31, 2015 included in our Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on March 15, 2016.

(7)For 2015, reflects a pro-rated salary for Dr. Darcis due to the fact that Dr. Darcis was appointed Executive Vice President and General Manager, Europe in July 2015. Dr. Darcis’ annual salary of £230,000 was paid in pounds sterling. The amount shown represents the salary payments made to Dr. Darcis based on an exchange rate of £1.5332 to $1.00, which is the average exchange rate for the period from July 1, 2015 to December 31, 2015.
(8)The amount shown represents the aggregate stipend paid to Dr. Darcis to purchase individually-obtained medical and life insurance benefits and pension benefits in 2015 (£2,378 pounds sterling, or approximately $3,646 U.S. dollars (converted from pounds sterling to U.S. dollars using an exchange rate of £1.5332 to $1.00, which was the average exchange rate for the period from July 1, 2015 to December 31, 2015), and his automobile allowance of £6,091 pounds sterling, or approximately $9,339 U.S. dollars (converted from pounds sterling to U.S. dollars using an exchange rate of £1.5332 to $1.00, which was the average exchange rate for the period from July 1, 2015 to December 31, 2015)Each of Drs. Galer and Farfel were granted performance-based stock options in October 2015 that were scheduled to vest upon the acceptance by the FDA of the NDA for Fintepla, provided such event occurred on or before the third anniversary of the date of grant. On September 28, 2018, prior to the date the options would have otherwise expired, our compensation committee accelerated the vesting of 90% of such stock options held by Drs. Galer and Farfel (13,500 and 6,750 options, respectively), in recognition of our significant progress towards the performance goal and their dedicated service for the three years since the grant date. Pursuant to SEC rules, for 2018, amounts reflected in the option column above for Drs. Galer and Farfel also include the fair value of modification to the vesting schedule for such awards equal to the incremental expense arising from the modification (computed in accordance with ASC 718) ($545,462 for Dr. Galer and $272,731 for Dr. Farfel).
(2)These amounts represent performance bonuses earned under our executive bonus program, which is described above under “Compensation Discussion and Analysis — Performance Bonuses.”
(9)For 2015, reflects a pro-rated salary for Mr. Hawley due to the fact that Mr. Hawley ceased serving as our Chief Executive Officer upon his resignation on April 27, 2015. He continues to serve as a member of our board of directors. Also includes $57,692 in vacation payout in connection with his termination of employment.
(10)Reflects severance in the amount of $500,000 paid to Mr. Hawley following his resignation from his position as our Chief Executive Officer, $25,000 paid to Mr. Hawley for post-termination consulting services, $17,033 in cash paid as a retainer to Mr. Hawley for his service as a non-employee director following his resignation, and $8,980 in continued health benefits provided to Mr. Hawley in connection with his separation agreement.
(3)The amounts represent 401(k) plan matching contributions paid by us and generally available to all full-time U.S. employees.

(4)In March 2017, we granted performance-based restricted stock units (“PSUs”) to our named executive officers (other than Messrs. Smith and Sagrolikar). The vesting of these performance-based RSUs is predicated on the approval by the U.S. Food and Drug Administration of a New Drug Application for Fintepla, provided such approval occurs within five years following the grant date, subject to the recipient’s continuous service to us on the vesting date. In accordance with ASC 718, the grant date fair value to be reported for PSUs in the Stock Awards column is determined based on the probable outcome of the performance condition as of the grant date. Due to the uncertainties associated with the FDA approval process, we determined approval is not yet probable, as such term is used for accounting purposes, prior to the occurrence of the event. Accordingly, we have reported a grant date fair value of $0 for these awards based on this evaluation. If we had determined that as of the date of the grant it was probable that the performance condition would be achieved, we would have reported the grant date fair value of these awards as follows: Dr. Farr, $280,500; Dr. Galer, $102,000 and Dr. Farfel, $89,250.

(5)Amounts reported for Mr. Smith’s 2017 salary and bonus received reflect pro-rated amounts for his January 16, 2017 start date. Mr. Smith’s option awards were granted in connection with his new hire compensation package.
41(6)Amounts reported for Mr. Sagrolikar’s 2018 salary received reflect pro-rated amounts for his July 2, 2018 start date. Pursuant to his employment agreement, his bonus received was not subject to proration for 2018. Mr. Sagrolikar’s 2018 stock and option awards were granted in connection with his new hire compensation package.

stock of $52.13 on December 31, 2019 by the number of RSUs the vesting of which accelerates in connection with the applicable triggering event. In the event of an involuntary termination without cause or resignation for good reason apart from a CIC and death/disability, shares subject to acceleration represent the vesting and exercisability of outstanding unvested RSUs as to the number of RSUs that would have vested over the 12-month period following termination had such officer remained continuously employed by us during such period. In the event of a change in control, shares subject to acceleration represent the vesting and exercisability of 50% of all outstanding unvested RSU awards and, in the event an executive officer is terminated without cause or resigns for good reason within 12 months following a change in control, shares subject to acceleration represent the vesting and exercisability of 100% of all outstanding unvested RSUs.
(4)Represents the aggregate value of the accelerated vesting of PSU awards, calculated by multiplying the fair market value of our common stock of $52.13 on December 31, 2019 by the number of PSUs the vesting of which accelerates in connection with the applicable triggering event. These PSU awards were granted in March 2017 and are not eligible for vesting on an accelerated basis pursuant to the terms of the employment agreements; provided that they will vest on an accelerated basis under the underlying PSU agreement as follows: (1) in the event of a change in control, the vesting of 50% of the executive officer’s outstanding unvested PSUs shall be automatically accelerated and (2) as a result of an involuntary termination without cause or resignation for good reason within 12 months after a change in control, the vesting of 100% of the executive officer’s outstanding unvested PSUs shall be automatically accelerated.
(1)Cash severance represents 12 months of base salary for each named executive officer, payable in cash in a lump sum.
(2)Value of equity award acceleration represents the value of those options that would immediately vest as a result of the named executive officer’s termination or as a result of the named executive officer’s death or disability. The value attributable to stock options not previously exercised that would vest in such event is the positive difference, if any, between the fair market value per share of our common stock on December 31, 2015 ($14.74) less the exercise price per share of such stock option multiplied by the number of shares that would vest.
(3)Cash severance represents the sum of the following, payable in a lump sum cash payment: (a) 12 months of base salary for each executive officer payable in a lump sum cash payment, plus (b) the average of the bonuses awarded to the executive officer for the fiscal years 2015, 2014 and 2013. The bonus amount for Dr. Galer is the average of his 2014 and 2015 bonus amounts. The bonus amount for each of Dr. Farfel and Dr. Darcis is equal to his or her bonus for 2015. Please see the definition of “bonus” under the heading “Employment Agreements” above.

48



(4)A named executive officer’s equity awards will vest in full in the event he or she is terminated without cause or he or she resigns for good reason within three months prior to or 12 months following a change in control, which is a slightly different trigger than applies to eligibility for cash severance. Value of equity award acceleration represents the value of those options that would immediately vest as a result of the named executive officer’s termination. The value attributable to stock options not previously exercised that would vest in such event is the positive difference, if any, between the fair market value per share of our common stock on December 31, 2015 ($14.74) less the exercise price per share of such stock option multiplied by the number of shares that would vest.
(5)Value of equity award acceleration represents the value of those options that would immediately vest upon a change in control without a termination of employment. The value attributable to stock options not previously exercised that would vest in such event is the positive difference, if any, between the fair market value per share of our common stock on December 31, 2015 ($14.74) less the exercise price per share of such stock option multiplied by the number of shares that would vest.
(6)Represents the value of the continuation of health benefits for a period of 12 months following the date of the named executive officer’s termination.
(7)Payment amounts for Dr. Darcis are converted from pounds sterling to U.S. dollars using an exchange rate of £1.48 to $1.00, which was the exchange rate in effect on December 31, 2015.

(5)Represents the value of the continuation of health benefits for a period of 12 months following the date of the named executive officer’s termination.
Risk Assessment of Compensation Program
In April 2016,2020, management assessed our compensation program for the purpose of reviewing and considering any risks presented by our compensation policies and practices that are reasonably likely to have a material adverse effect on us. As part of that assessment, management reviewed the primary elements of our compensation program, including base salary, short-term incentive compensation and long-term incentive compensation. Management’s risk assessment included a review of the overall design of each primary element of our compensation program, and an analysis of the various design features, controls and approval rights in place with respect to compensation paid to management and other employees that mitigate potential risks to us that could arise from our compensation program. Following the assessment, management determined that our compensation policies and practices did not create risks that were reasonably likely to have a material adverse effect on us and reported the results of the assessment to our compensation committee.
CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are required to disclose the ratio of the annual total compensation of our CEO to the annual total
compensation of our median compensated employee, using the required calculations. The pay ratio included in this information is a reasonable estimate calculated in a manner that is intended to be consistent with Item 402(u) of Regulation S-K.
As of December 31, 2019, our employee population consisted of 141 individuals, as compared to 68 individuals when we initially identified the median employee for purposes of the pay ratio disclosed in our 2018 proxy statement, with the same median employee also used in our 2019 proxy statement. Accordingly, we determined that we had experienced a significant change in our employee population and needed to re-identify the median employee. To identify the median employee for fiscal 2019, we looked at our employee population as of December 31, 2019 and determined each such employee’s fiscal 2019 compensation consisting of base salary and performance bonus, our consistently applied compensation measure. Additional information regarding our methodology includes the following:
for employees who were hired in 2019, but did not work for us for the entire fiscal year, we annualized their compensation as if they had been employed by us for all of 2019;
no cost of living adjustments were applied;
for an employee paid in a currency other than U.S. dollars, their compensation was converted into U.S. dollars, using exchange rates as of December 31, 2019; and
six employees working in Germany, Italy and Ireland (consisting of two employees in each country) for our newly created subsidiaries in 2019 were excluded from our employee population, as permitted under SEC rules, because they represented less than 5% of our employee population.
Once we identified the median employee, we calculated the components of the median employee’s compensation for 2019 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.
For 2019, our last completed fiscal year:
our CEO’s annual total compensation, as reported in the Summary Compensation Table included elsewhere in this Proxy Statement, was $10,346,750; and
our median employee’s annual total compensation was $337,830.
Based on this information, our 2019 CEO to median employee pay ratio was 31 to 1.
40


This pay ratio disclosure is a reasonable estimate. Because the SEC rules for identifying the median employee and calculating the pay ratio permit companies to use various methodologies and assumptions, to apply certain exclusions and to make reasonable estimates that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable with the pay ratio that we have reported.

APPENDIX A
ZOGENIX, INC.
EMPLOYEE STOCK PURCHASE PLAN
(As Amended and Restated Effective May 29, 2020)
ARTICLE I
PURPOSE
The purposes of this Zogenix, Inc. Employee Stock Purchase Plan (the “Plan”) are to assist Eligible Employees of Zogenix, Inc., a Delaware corporation (the “Company”) and its Designated Subsidiaries in acquiring a stock ownership interest in the Company, and to help Eligible Employees provide for their future security and to encourage them to remain in the employment of the Company and its Designated Subsidiaries. This Plan constitutes an amendment and restatement of the Zogenix, Inc. 2010 Employee Stock Purchase Plan (the “PriorPlan”), which was approved by the Board on October 25, 2010 and by the Company’s stockholders on November 2, 2010. In the event that the Company’s stockholders do not approve the Plan, the Prior Plan will continue in full force and effect on its terms and conditions as in effect immediately prior to the date the Plan is approved by the Board.
This Plan includes two components: the Section 423 Component and the Non-Section 423 Component (each as defined below). It is the intention of the Company to have the Section 423 Component qualify as an “employee stock purchase plan” under Section 423 of the Code. The provisions of the Section 423 Component, accordingly, shall be construed so as to extend and limit participation on a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes the grant of purchase rights under the Non-Section 423 Component, which may not qualify as an “employee stock purchase plan” under Section 423 of the Code; such purchase rights granted under the Non-Section 423 Component shall be granted pursuant to separate Offerings containing such sub-plans, appendices, rules or procedures as may be adopted by the Administrator and designed to achieve tax, securities laws or other objectives for Eligible Employees and the Designated Subsidiaries in locations outside of the U.S. Except as otherwise provided by the Administrator or permitted herein, the Non-Section 423 Component will operate and be administered in the same manner as the Section 423 Component. Offerings intended to be made under the Non-Section 423 Component will be designated as such by the Administrator at or prior to the time of such Offering.
For purposes of this Plan, the Administrator may designate separate Offerings under the Plan in which Eligible Employees will participate. The terms of these Offerings need not be identical, even if the dates of the applicable Offering Period(s) in each such Offering are identical, provided that the terms of participation are the same within each separate Offering under the Section 423 Component (as determined under Section 423 of the Code). Solely by way of example and without limiting the foregoing, the Company could, but shall not be required to, provide for simultaneous Offerings under the Section 423 Component and the Non-Section 423 Component of the Plan.
ARTICLE II
DEFINITIONS AND CONSTRUCTION
Wherever the following terms are used in the Plan they shall have the meanings specified below, unless the context clearly indicates otherwise. The singular pronoun shall include the plural where the context so indicates.
2.1Administratorshall mean the entity that conducts the general administration of the Plan as provided herein. The term Administrator shall refer to the Committee unless the Board has assumed the authority for administration of the Plan generally as provided in Article 3.

(c)The consummation by the Company (whether directly involving the Company or indirectly involving the Company through one or more intermediaries) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions or (z) the acquisition of assets or stock of another entity, in each case other than a transaction:

(ii)After which no person or group beneficially owns voting securities representing 50% or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this clause (ii) as beneficially owning 50% or more of combined voting power of the Successor Entity solely as a result of the voting power held in the Company prior to the consummation of the transaction. The Administrator shall have full and final authority, which shall be exercised in its discretion, to determine conclusively whether a Change in Control of the Company has occurred pursuant to the above definition, and the date of the occurrence of such Change in Control and any incidental matters relating thereto.

2.8“Designated Subsidiary” shall mean any Subsidiary designated by the Administrator in accordance with Section 3.3(b), such designation to specify whether such participation is in the Section 423 Component or Non-Section 423 Component; provided, however, that at any given time, a Subsidiary Corporation that is a Designated Subsidiary participating in the Section 423 Component will not be a Designated Subsidiary participating in the Non-Section 423 Component. The designation by the Administrator of Designated Subsidiaries and changes in such designations by the Administrator shall not require stockholder approval. Only Subsidiary Corporations may be designated as Designated Subsidiaries for purposes of the Section 423 Component, and if an entity does not so qualify, it shall automatically be deemed to be a Designated Subsidiary in the Non-Section 423 Component.
2.9Eligible Employee” shall mean an Employee of the Company or a Designated Subsidiary who does not, immediately after any rights under this Plan are granted, own (directly or through attribution) stock possessing 5% or more of the total combined voting power or value of all classes of Stock or other stock of the Company, a Parent or a Subsidiary Corporation (as determined under Section 423(b)(3) of the Code). For purposes of the foregoing sentence, the rules of Section 424(d) of the Code with regard to the attribution of stock ownership shall apply in determining the stock ownership of an individual, and Stock that an Employee may purchase under outstanding options shall be treated as stock owned by the Employee. Notwithstanding the foregoing, the Administrator may provide in an Offering Document that an Employee shall not be eligible to participate in an Offering if: (a) such Employee's customary employment is for twenty hours or less per week; (b) such Employee's customary employment is for less than five months in any calendar year; (c) such Employee is a highly compensated employee within the meaning of Section 423(b)(4)(D) of the Code, (d) such Employee has not met a service requirement designated by the Administrator pursuant to Section 423(b)(4)(A) of the Code (which service requirement may not exceed two years); and/or (e) such Employee is a citizen or resident of a foreign jurisdiction if the grant of a right to purchase Stock under the Plan to such Employee would be prohibited under the laws of such foreign jurisdiction or the grant of an option to such Employee in compliance with the laws of such foreign jurisdiction would cause the Plan or any Offering to violate the requirements of Section 423 of the Code, as determined by the Administrator in its sole discretion; provided, further, that any exclusion in clauses (a), (b), (c), (d) or (e) shall be applied in an identical manner under each

The terms and conditions applicable to each Offering during an Offering Period shall be set forth in an Offering Documentadopted by the Administrator, which Offering Document shall be in such form and shall contain such terms and conditions as the Administrator shall deem appropriate and shall be incorporated by reference into and made part of the Plan and shall be attached hereto as part of the Plan. The Administrator shall establish in each Offering Document one or more dates during an Offering Period (the “Purchase Date(s)”) on which rights granted under the Plan shall be exercised and purchases of Stock carried out during such Offering Period in accordance with such Offering Document and the Plan.

PARTICIPATION
6.1Eligibility. Any Eligible Employee who shall be employed by the Company or a Designated Subsidiary on the day immediately preceding a given Enrollment Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of this Article 6 and, for the Section 423 Component, the limitations imposed by Section 423(b) of the Code.
6.2Enrollment in Plan. Except as otherwise set forth in an Offering Document, an Eligible Employee may become a Participant in the Plan for an Offering Period by delivering a subscription agreement to the Company prior to the Enrollment Date for such Offering Period (or such other date specified in the Offering Document), in such form as the Administrator provides. Except as provided in Section 6.7, each such agreement shall designate a whole percentage of such Eligible Employee’s Compensation to be withheld by the Company or the Designated Subsidiary employing such Eligible Employee on each payday during the Offering Period as payroll deductions under the Plan. Except as provided in Section 6.7, an Eligible Employee may designate any whole percentage of Compensation which is not less than 1% and not more than the maximum percentage specified by the Administrator in the applicable Offering Document (which percentage shall be 20% in the absence of any such designation) as payroll deductions. A Participant may reduce or increase the percentage of Compensation designated in his or her subscription agreement, or may suspend his or her payroll deductions, subject to the limits of this Section 6.2 at any time during an Offering Period; provided, however, that the Administrator may limit the number of changes a Participant may make to his or her payroll deduction elections during each Offering Period and/or Purchase Period in the applicable Offering Document (and in the absence of any specific designation by the Administrator, a Participant shall be allowed two changes to his or her payroll deduction elections during each Offering Period); provided, further, that in no event may an Eligible Employee increase the percentage of Compensation designated in his or her subscription agreement more than once during an Offering Period and any such increase shall be permitted only at such times as specified by the Administrator in the applicable Offering Document. Any such change to payroll deductions shall be effective with the first full payroll period following five business days after the Company’s receipt of the new subscription agreement (or such shorter or longer period as may be specified by the Administrator in the applicable Offering Document). Except as otherwise set forth in an Offering Document, a Participant may participate in the Plan only by means of payroll deduction and may not make contributions by lump sum payment for any Offering Period (and if contributions are permitted, the foregoing provisions shall apply to such contributions). In the event a Participant suspends his or her payroll deductions, such Participant’s cumulative payroll deductions prior to the suspension shall remain in his or her account and shall be applied to the purchase of shares of Stock on the next occurring Purchase Date and shall not be paid to such Participant unless he or she withdraws from participation in the Plan pursuant to Article 8.
6.3Payroll Deductions. Except as otherwise provided in the applicable Offering Document, payroll deductions for a Participant shall commence on the first payroll following the Enrollment Date and shall end on the last payroll in the Offering Period to which his or her authorization is applicable, unless sooner terminated by the Participant as provided in Article 9 or suspended by the Participant as provided in Section 6.2 or the Administrator as provided in Section 6.6. The payroll deductions made for each Participant shall be credited to an account for such Participant under the Plan and shall be deposited with the general funds of the Company.
6.4Effect of Enrollment. A Participant’s completion of a subscription agreement will enroll such Participant in the Plan for each successive Purchase Period and each subsequent Offering Period on the terms contained therein until the Participant either submits a new subscription agreement, withdraws from participation under the Plan as provided in Article 8 or otherwise becomes ineligible to participate in the Plan.
6.5Limitation on Purchase of Stock. An Eligible Employee may be granted rights under the Plan only if such rights, together with any other rights granted to such Eligible Employee under “employee stock purchase plans” of the Company, any Parent or any Subsidiary Corporation, as specified by Section 423(b)(8) of the Code, do not permit such employee’s rights to purchase stock of the Company or any Parent or Subsidiary Corporation to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined as of the first day of the Offering Period during which such rights are granted) for each calendar year in which such rights are outstanding at any time. This limitation shall be applied in accordance with Section 423(b)(8) of the Code.
A-6


6.6Decrease or Suspension of Payroll Deductions. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 6.5 or the other limitations set forth in this Plan, a Participant’s payroll deductions may be suspended by the Administrator at any time during an Offering Period. The balance of the amount credited to the account of each Participant which has not been applied to the purchase of shares of Stock by reason of Section 423(b)(8) of the Code, Section 6.5 or the other limitations set forth in this Plan shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable after the Purchase Date.
6.7Foreign Employees.
(a)In order to facilitate participation in the Plan, the Administrator may provide for such special terms applicable to Participants who are citizens or residents of a foreign jurisdiction, or who are employed by a Designated Subsidiary outside of the United States, as the Administrator may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Except as permitted by Section 423 of the Code, with respect to Offerings under the Section 423 Component, such special terms may not be more favorable than the terms of rights granted under the Section 423 Component to Eligible Employees who are residents of the United States. Such special terms may be set forth in an addendum to the Plan in the form of a sub-plan, addendum or appendix to this Plan, which sub-plan, addendum or appendix may be designed to govern Offerings under the Section 423 Component or the Non-Section 423 Component, as determined by the Administrator. Such sub-plans, addendums or appendices may take precedence over other provisions of this Plan, with the exception of Sections 4.1 and 10.1 and Article 11, but unless otherwise expressly superseded thereby, the provisions of this Plan shall govern the operation of such sub-plans, addendums or appendices; provided, however, that no action under this Section 6.7 shall be effective if it would cause the Section 423 Component to fail to continue to constitute an “employee stock purchase plan” within the meaning of Section 423(b) of the Code. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures, with respect to Participants who are foreign nationals or employed in non-U.S. jurisdictions, regarding the exclusion of particular Subsidiaries from participation in the Plan, eligibility to participate, the definition of Compensation, handling of payroll deductions or other contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, establishment of bank or trust accounts to hold payroll deductions or contributions, determination of beneficiary designation requirements, and handling of stock certificates. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of a purchase right granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of purchase rights granted under the Plan or the same Offering to Employees resident solely in the U.S. To the extent any sub-plan, addendum or appendix or other changes approved by the Administrator are inconsistent with the requirements of Section 423 of the Code or would jeopardize the tax-qualified status of the Section 423 Component, the change shall cause the Designated Subsidiaries affected thereby to be considered Designated Subsidiaries in a separate Offering under the Non-Section 423 Component instead of the Section 423 Component. To the extent any Employee of a Designated Subsidiary in the Section 423 Component is a citizen or resident of a foreign jurisdiction (without regard to whether they are also a U.S. citizen or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Code)) and compliance with the laws of the foreign jurisdiction would cause the Section 423 Component or any Offering to violate the requirements of Section 423 of the Code, such Employee shall be considered a Participant in a separate Offering under the Non-Section 423 Component. Unless specifically required under Article 11, the Administrator shall not be required to obtain the approval of the stockholders of the Company prior to the adoption, amendment or termination of any such sub-plan, appendix, rules or procedures.
(b)Notwithstanding any other provisions of the Plan to the contrary, in non-U.S. jurisdictions where participation in the Plan through payroll deductions is prohibited, the Administrator may provide that an Eligible Employee may elect to participate through contributions to his or her account under the Plan in a form acceptable to the Administrator in lieu of or in addition to payroll deductions; provided, however, that, for any Offering under the Section 423 Component, the Administrator shall ensure that any alternative method of contribution is applied on an equal and uniform basis to all Eligible Employees in the Offering in compliance with Section 423 of the Code.
ARTICLE VII
GRANT AND EXERCISE OF RIGHTS
7.1Grant of Rights. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period shall be granted a right to purchase the maximum number of shares of Stock specified under Section 5.2(d), subject to the limits in Section 6.5, and shall have the right to buy, on each Purchase Date during such Offering Period (at the applicable Purchase Price), such number of shares of the Company’s Stock as is determined by dividing (a) such Participant’s payroll deductions accumulated prior to such Purchase Date and retained in the Participant’s account as of the Purchase Date, by (b) the applicable Purchase Price. The right shall expire on the last day of the Offering Period.
7.2Exercise of Rights. On each Purchase Date, each Participant’s accumulated payroll deductions and any other additional payments specifically provided for in the applicable Offering Document will be applied to the purchase of whole shares of Stock of the Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering
A-7


Document, at the Purchase Price. No fractional shares shall be issued upon the exercise of rights granted under the Plan, unless the Offering Document specifically provides otherwise. Any cash in lieu of fractional shares of Stock remaining after the purchase of whole shares of Stock upon exercise of a purchase right will be credited to a Participant’s account and carried forward and applied toward the purchase of whole shares of Stock for the next following Offering Period. Shares of Stock issued pursuant to the Plan may be evidenced in such manner as the Administrator may determine and may be issued in certificated form or issued pursuant to book-entry procedures.
7.3Pro Rata Allocation of Shares. If the Administrator determines that, on a given Purchase Date, the number of shares of Stock with respect to which rights are to be exercised may exceed (a) the number of shares of Stock that were available for issuance under the Plan on the Enrollment Date of the applicable Offering Period, or (b) the number of shares of Stock available for issuance under the Plan on such Purchase Date, the Administrator may in its sole discretion provide that the Company shall make a pro rata allocation of the shares of Stock available for purchase on such Enrollment Date or Purchase Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants for whom rights to purchase Stock are to be exercised pursuant to this Article 7 on such Purchase Date, and shall either (a) continue all Offering Periods then in effect, or (b) terminate any or all Offering Periods then in effect pursuant to Article 10. The Company may make pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date. The balance of the amount credited to the account of each Participant which has not been applied to the purchase of shares of Stock shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable after the Purchase Date.
7.4Withholding. At the time a Participant’s rights under the Plan are exercised, in whole or in part, or at the time some or all of the Stock issued under the Plan is disposed of, the Participant must make adequate provision for the Company’s (or any Parent's or Subsidiary’s) federal, state, foreign or other tax withholding obligations, if any, which arise upon the exercise of the right or the disposition of the Stock. At any time, the Company may, but shall not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company (or any Parent or Subsidiary) to meet applicable withholding and/or social insurance obligations, including any withholding required to make available to the Company (or any Parent or Subsidiary) any tax deductions or benefits attributable to sale or early disposition of Stock by the Participant.
7.5Conditions to Issuance of Stock. The Company shall not be required to issue or deliver any certificate or certificates for, or make any book entries evidencing, shares of Stock purchased upon the exercise of rights under the Plan prior to fulfillment of all of the following conditions:
(a)The admission of such shares to listing on all stock exchanges, if any, on which the Stock is then listed; and
(b)The completion of any registration or other qualification of such shares under any state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Administrator shall, in its absolute discretion, deem necessary or advisable; and
(c)The obtaining of any approval or other clearance from any state or federal governmental agency which the Administrator shall, in its absolute discretion, determine to be necessary or advisable; and
(d)The payment to the Company of all amounts which it is required to withhold under federal, state, foreign or local law upon exercise of the rights, if any; and
(e)The lapse of such reasonable period of time following the exercise of the rights as the Administrator may from time to time establish for reasons of administrative convenience.
ARTICLE VIII
WITHDRAWAL; TERMINATION OF EMPLOYMENT OR ELIGIBILITY
8.1Withdrawal. A Participant may withdraw all but not less than all of the payroll deductions credited to his or her account and not yet used to exercise his or her rights under the Plan at any time by giving written notice to the Company in a form acceptable to the Administrator no later than one (1) week prior to the end of the Offering Period (or such shorter or longer period as the Administrator may provide). All of the Participant’s payroll deductions credited to his or her account during an Offering Period shall be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal and such Participant’s rights for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be made for such Offering Period. If a Participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the next Offering Period unless the Participant delivers to the Company a new subscription agreement.
8.2Future Participation. A Participant’s withdrawal from an Offering Period shall not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or a Designated Subsidiary or in subsequent Offering Periods which commence after the termination of the Offering Period from which the Participant withdraws.
A-8


8.3Cessation of Eligibility. Upon a Participant’s ceasing to be an Eligible Employee for any reason, he or she shall be deemed to have elected to withdraw from the Plan pursuant to this Article 8 and the payroll deductions credited to such Participant’s account during the Offering Period shall be paid to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 12.4, as soon as reasonably practicable, and such Participant’s rights for the Offering Period shall be automatically terminated.
8.4Transfer of Employment. A transfer of employment from one Designated Subsidiary to another shall not be treated as a termination of employment. If a Participant transfers employment from the Company or any Designated Subsidiary participating in the Section 423 Component to a Designated Subsidiary participating in the Non-Section 423 Component, he or she shall immediately cease to participate in the Section 423 Component; however, any payroll deductions made for the Offering Period in which such transfer occurs shall be transferred to the Non-Section 423 Component, and such Participant shall immediately join the then-current Offering under the Non-Section 423 Component upon the same terms and conditions in effect for his or her participation in the Section 423 Component, except for such modifications otherwise applicable for Participants in such Offering. A Participant who transfers employment from a Designated Subsidiary participating in the Non-Section 423 Component to the Company or any Designated Subsidiary participating in the Section 423 Component shall remain a Participant in the Non-Section 423 Component until the earlier of (i) the end of the current Offering Period under the Non-Section 423 Component, or (ii) the Enrollment Date of the first Offering Period in which he or she is eligible to participate following such transfer. Notwithstanding the foregoing, the Administrator may establish different rules to govern transfers of employment between companies participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable requirements of Section 423 of the Code.
ARTICLE IX
ADJUSTMENTS UPON CHANGES IN STOCK

Subject to Section 9.3, in the event that the Administrator determines that any dividend or other distribution (whether in the form of cash, Stock, other securities, or other property), Change in Control, reorganization, merger, amalgamation, consolidation, combination, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Stock or other securities of the Company, issuance of warrants or other rights to purchase Stock or other securities of the Company, or other similar corporate transaction or event, as determined by the Administrator, affects the Stock such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any outstanding purchase rights under the Plan, the Administrator shall make equitable adjustments, if any, to reflect such change with respect to (a) the aggregate number and type of shares of Stock (or other securities or property) that may be issued under the Plan (including, but not limited to, adjustments of the limitations in Section 4.1 and the limitations established in each Offering Document pursuant to Section 5.2 on the maximum number of shares of Stock that may be purchased); (b) the class(es) and number of shares and price per share of Stock subject to outstanding rights; and (c) the Purchase Price with respect to any outstanding rights.
9.2.Other Adjustments. Subject to Section 9.3, in the event of any transaction or event described in Section 9.1 or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate (including without limitation any Change in Control), or of changes in applicable laws, regulations or accounting principles, and whenever the Administrator determines that such action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any right under the Plan, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles, the Administrator, in its sole discretion and on such terms and conditions as it deems appropriate, is hereby authorized to take any one or more of the following actions:
(a)To provide for either (i) termination of any outstanding right in exchange for an amount of cash, if any, equal to the amount that would have been obtained upon the exercise of such right had such right been currently exercisable or (ii) the replacement of such outstanding right with other rights or property selected by the Administrator in its sole discretion;
(b)To provide that the outstanding rights under the Plan shall be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar rights covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices; and
(c)To make adjustments in the number and type of shares of Stock (or other securities or property) subject to outstanding rights under the Plan and/or in the terms and conditions of outstanding rights and rights which may be granted in the future;
A-9


(d)To provide that Participants’ accumulated payroll deductions may be used to purchase Stock prior to the next occurring Purchase Date on such date as the Administrator determines in its sole discretion and the Participants’ rights under the ongoing Offering Period(s) terminated; and
(e)To provide that all outstanding rights shall terminate without being exercised.
9.3.No Adjustment Under Certain Circumstances. No adjustment or action described in this Article 9 or in any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause the Section 423 Component of the Plan to fail to satisfy the requirements of Section 423 of the Code.
9.4.No Other Rights. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to a Participant’s right to purchase or the grant or exercise price of any such right to purchase shares of Stock.
ARTICLE X
AMENDMENT, MODIFICATION AND TERMINATION
10.1Amendment, Modification and Termination. The Administrator may amend, suspend or terminate the Plan at any time and from time to time; provided, however, that approval by a vote of the holders of the outstanding shares of the Company’s capital stock entitled to vote shall be required to amend the Plan to: (a) increase the aggregate number, or change the type, of shares that may be sold pursuant to rights under the Plan under Section 4.1 (other than any adjustment as provided by Article 9); (b) change the corporations or classes of corporations whose employees may be granted rights under the Plan; (c) change the Plan in any manner that would cause the Section 423 Component of the Plan to no longer be an “employee stock purchase plan” within the meaning of Section 423(b) of the Code; or (d) amend the Plan in any manner that would require the approval of the Company’s stockholders under applicable law or the rules of the stock exchange on which the shares of Stock are listed.
10.2Rights Previously Granted. Except as provided in Article 9 or this Article 10, no termination, amendment or modification may make any change in any right theretofore granted which adversely affects the rights of any Participant without the consent of such Participant, provided that an Offering Period may be terminated, amended or modified by the Administrator if the Administrator determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its stockholders.
10.3Certain Changes to Plan. Without stockholder consent and without regard to whether any Participant rights may be considered to have been adversely affected (and, with respect to the Section 423 Component, to the extent permitted by Section 423 of the Code), the Administrator shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan.
ARTICLE XI
TERM OF PLAN
This amended and restated Plan shall be effective on the date it is approved by the stockholders of the Company (the “Restatement Effective Date”). The Plan shall be in effect until terminated under Article 10. No rights may be granted under the Plan during any period of suspension of the Plan or after termination of the Plan. This amended and restated Plan will be submitted for the approval of the Company’s stockholders within twelve (12) months after the date of the Board’s initial adoption of the Plan. If this amended and restated Plan is not approved by the Company’s stockholders, it will not become effective and the Prior Plan will continue in full force and effect in accordance with its terms.
ARTICLE XII
MISCELLANEOUS
A-10


12.1Restriction upon Assignment. A right granted under the Plan shall not be transferable other than by will or the laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant. Except as provided in Section 12.4 hereof, a right under the Plan may not be exercised to any extent except by the Participant. The Company shall not recognize and shall be under no duty to recognize any assignment or alienation of the Participant’s interest in the Plan, the Participant’s rights under the Plan or any rights thereunder.
12.2Rights as a Stockholder. With respect to shares of Stock subject to a right granted under the Plan, a Participant shall not be deemed to be a stockholder of the Company, and the Participant shall not have any of the rights or privileges of a stockholder, until such shares have been issued to the Participant or his or her nominee following exercise of the Participant’s rights under the Plan. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other property) or distribution or other rights for which the record date occurs prior to the date of such issuance, except as otherwise expressly provided herein.
12.3Use of Funds; Interest. All funds received or held by the Company under the Plan shall be included in the general funds of the Company free of any trust or other restriction and may be used for any corporate purpose, except for funds contributed under Offerings in which the local law of a non-U.S. jurisdiction requires that contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party for Participants in non-U.S. jurisdictions. No interest shall accrue on the payroll deductions or lump sum contributions of a Participant under the Plan, except as may be required by local law in a non-U.S. jurisdiction. If the segregation of funds and/or payment of interest on any Participant’s account is so required, such provisions shall apply to all Participants in the relevant Offering except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f). With respect to any Offering under the Non-Section 423 Component, the payment of interest shall apply as determined by the Administrator (but absent any such determination, no interest shall apply).
12.4Designation of Beneficiary.
(a)A Participant may, in the manner determined by the Administrator, file a written designation of a beneficiary who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to a Purchase Date on which the Participant’s rights are exercised but prior to delivery to such Participant of such shares and cash. In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the Participant’s rights under the Plan. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as his or her beneficiary shall not be effective without the prior written consent of the Participant’s spouse.
(b)Such designation of beneficiary may be changed by the Participant at any time by written notice to the Company. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.
12.5Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.
12.6Equal Rights and Privileges. All Eligible Employees of the Company or any Designated Subsidiary under the Section 423 Component will have equal rights and privileges under this Plan so that the Section 423 Component of the Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Any provision of the Section 423 Component of the Plan that is inconsistent with Section 423 of the Code will, without further act or amendment by the Company, the Board or the Administrator, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. Participants participating in the Non-Section 423 Component need not have the same rights and privileges as Eligible Employees participating in the Section 423 Component or other Eligible Employees participating in the Non-Section 423 Component.
12.7Reports. Statements of account shall be given to participating Employees at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any.
12.8No Employment Rights. Nothing in the Plan shall be construed to give any person (including any Eligible Employee or Participant) the right to remain in the employ of the Company or any Parent or Subsidiary or to affect the right of the Company or any Parent or Subsidiary to terminate the employment of any person (including any Eligible Employee or Participant) at any time, with or without cause.
12.9Notice of Disposition of Shares. Each Participant in the Section 423 Component shall give prompt notice to the Company of any disposition or other transfer of any shares of Stock purchased upon exercise of a right under the Plan if such
A-11


disposition or transfer is made: (a) within two years from the Enrollment Date of the Offering Period in which the shares were purchased or (b) within one year after the Purchase Date on which such shares were purchased. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by the Participant in such disposition or other transfer.
12.10Governing Law. The validity and enforceability of this Plan shall be governed by and construed in accordance with the laws of the State of California without regard to otherwise governing principles of conflicts of law.
12.11Electronic Forms. To the extent permitted by applicable law and in the discretion of the Administrator, an Eligible Employee may submit any form or notice as set forth herein by means of an electronic form approved by the Administrator. Before the commencement of an Offering Period, the Administrator shall prescribe the time limits within which any such electronic form shall be submitted to the Administrator with respect to such Offering Period in order to be a valid election.

Any capitalized terms used in this Sub-Plan but not defined shall have the meaning given to those terms in the Plan.

2.GLOBAL PROVISIONS
(a)Data Protection. It shall be a term and condition for participation in the Plan that a Participant explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of a Participant’s personal “Data” (as defined below) by and among, as applicable, the Company, any Parent or Subsidiary and a Participant’s employing entity (the “Employer”), if different, and their affiliates (collectively, the “Company Group”) for the exclusive purpose of implementing, administering and managing the Participant’s participation in the Plan. The Company Group holds certain personal information about the Participant, including, but not limited to, the Participant’s name, home address and telephone number, e-mail address, date of birth, employee identification number, NRIC or passport number or equivalent, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all options or any other entitlement to shares of stock awarded, canceled, exercised, vested, unvested or outstanding in the Participant’s favor, for the purpose of implementing, administering and managing the Plan (“Data”).

The recipients of the Data may be located in the United States of America or elsewhere (and, if the Participant is a resident of a member state of the European Union, may be outside the European Economic Area) and that the recipient’s country (e.g., the United States of America) may have different data privacy laws and protections than the Participant’s country. The Participant may request a list with the names and addresses of all recipients of the Data by contacting his or her local human resources representative. Each Participant hereby authorizes the Company Group and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Participant’s participation in the Plan.

A Participant may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case, without cost, by contacting in writing the Participant’s local human resources representative. A Participant’s refusal to provide consent or withdrawal of consent may affect the Participant’s ability to participate in the Plan. This section applies to information held, used or disclosed in any medium.

If Participant resides in the UK or the European Union, the Company Group will hold, collect and otherwise process certain Data as set out in the applicable Company’s GDPR-compliant data privacy notice, which will be or has been provided to the Participant separately. All personal data will be treated in accordance with applicable data protection laws and regulations.
(b)Acknowledgment of Nature of Plan and Rights. In participating in the Plan, each Participant acknowledges that:
(i)for employment and labor law purposes, the rights granted and the shares of Stock purchased under the Plan are an extraordinary item that do not constitute wages of any kind for services of any kind rendered to the Company, any Parent or Subsidiary or the Employer, and the award of rights is outside the scope of Participant’s service contract, if any;
(ii)for employment and labor law purposes, the rights granted and the Stock purchased under the Plan are not part of normal or expected wages or salary for any purposes, including, but not limited to, calculation of any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, holiday pay, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company, the Employer, its Parent or any Subsidiary of the Company;
(iii)the rights and the shares of Stock purchased under the Plan are not intended to be an integral component of compensation or to replace any pension rights or compensation;
A-13


(iv)neither the rights nor any provision of Plan or the policies adopted pursuant to the Plan confer upon any Participant any right with respect to service or continuation of current service and shall not be interpreted to form a service contract or relationship with the Company or any Subsidiary;
(v)the future value of the underlying shares of Stock is unknown and cannot be predicted with certainty;
(vi)if the underlying shares of Stock do not increase in value, the right may have no value; and
(vii)if a Participant acquires shares of Stock, the value of the shares of Stock acquired upon purchase may increase or decrease in value, even below the original price paid.

INTERNATIONAL PARTICIPANTS

UNITED KINGDOM
1.APPLICATION

2.TAX CONSEQUENCES
(a)The Eligible Employee agrees to indemnify and keep indemnified the Company Group from and against any liability for or obligation to pay any tax liability that is attributable to: (i) the grant or exercise of a right under the Plan; (ii) the acquisition by the Eligible Employee of shares of Stock on exercise of the right; or (iii) the disposal of any shares of Stock (each, a “Tax Liability”).
(b)At the discretion of the Administrator, purchase rights granted under the Plan cannot be exercised until the Eligible Employee has entered into an election with the Company or the Employer as appropriate (in a form approved by the Employer and HMRC) (a “joint election”) under which any liability of the Company Group for Employer’s National Insurance Contributions arising in respect of the grant, exercise of or other dealing in the rights granted under the Plan, or the acquisition of shares of Stock on exercise of the right, is transferred to and met by the Eligible Employee.
(c)Without prejudice to the terms of the Plan, rights cannot be exercised until the Eligible Employee has made such arrangements as the Company Group may require for the satisfaction of any Tax Liability that may arise in connection with the exercise of the right and/or the acquisition of the shares of Stock by the Eligible Employee.

(i)deduction from salary or other payments due to the Eligible Employee;
(ii)withholding the issue, allotment or transfer to the Eligible Employee of that number of shares of Stock (otherwise to be acquired by the Eligible Employee on the exercise of the right) whose aggregate market value on date of exercise is, so far as possible, equal to, but not less than, the amount of Tax Liability (together with the fees and expenses incurred in the sale of the shares of Stock, where the Company intends to sell the shares to meet the Tax Liability);
(iii)withholding the issue, allotment or transfer to the Eligible Employee of the shares of Stock otherwise to be acquired by the Eligible Employee pursuant to the right until the Eligible Employee has demonstrated to the satisfaction of the Company Group that he has given irrevocable instructions to a third party (for example, a broker) satisfactory to the Company Group to sell a sufficient number of those shares to ensure the net proceeds are so far as possible, equal to but not less than, the amount of the Tax Liability; or
(iv)where the Tax Liability arises as a result of a release or assignment by the Eligible Employee of the right, a deduction from the payment made to him as consideration for such release or assignment.

(d)Section 2(c) of this Sub-Plan will not apply where the Eligible Employee has, before the allotment, issuance or transfer of the shares of Stock to be issued or transferred to the Eligible Employee as a result of the exercise of the right, paid to the Company Group, in cleared funds a sum equal to the Tax Liability arising on the exercise of the right.
