entitled to vote at the annual meeting will constitute a quorum to transact business at the annual meeting. Abstentions, “WITHHOLD” votes, and “broker non-votes” are counted as present and entitled to vote for purposes of determining a quorum. If there is no quorum, the chairmanChair of the meeting may adjourn the meeting to another time or place.

What are broker non-votes?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee, as applicable, as to how to vote on matters deemed “non-routine” and there is at least one “routine” matter to be voted upon at the annual meeting. Generally, if shares are held in “street name,” the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not

TABLE OF CONTENTS
provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. In the event that a broker, bank or other nominee votes shares on the “routine” matters, but does not vote shares on the “non-routine” matters, those shares will be treated as broker non-votes with respect to the “non-routine” proposals. Accordingly, if you ownare a beneficial owner of shares through a nominee, such as a broker, bank, or bank,other nominee, please be sure to instruct your broker, bank, or other nominee how to vote to ensure that your vote is counted on each of the proposals.

What matters are considered “routine” and “non-routine”?

The ratification of the appointment of PwC as our independent registered public accounting firm for our fiscal year ending December 31, 2018 (Proposal2024 (“Proposal No. 2)2”) is considered “routine” under applicable federal securities rules. The election of Class II directors (Proposal(“Proposal No. 1)1”), and the approvaladvisory non-binding vote to approve the compensation of the 2018 Employee Stock Purchase Plan (Proposalour named executive officers (“Proposal No. 3)3”) are considered “non-routine” under applicable federal securities rules.

What are the effects of abstentions and broker non-votes?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee causes abstentions to be recorded for shares, these sharesAbstentions will be considered as shares present and entitled to vote at the annual meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the voting power of the shares present virtually or represented by proxy and entitled to vote aton the annual meetingproposal (Proposals No. 2 and No. 3). However, because the outcome of Proposal No. 1 (election of directors) will be determined by a plurality vote, you may only vote “FOR” or “WITHHOLD” for each nominee and abstentions will have no impact on the outcome of such proposal as long as a quorum exists.

Broker non-votes will be counted for purposes of calculating whether a quorum is present at the annual meeting but will not be counted for purposes of determining the number of votes castvoting power entitled to vote on a proposal. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on any of the proposals.

What is the voting requirement to approve each of the proposals?

Proposal No. 1: Election of Class II Directors.Directors.The election of Class II directors requires a plurality of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote on the election of directors. This means that the twothree nominees for Class II director receiving the highest number of “FOR” votes will be elected as Class II directors. You may vote (i) “FOR” for each director nominee or (ii) “WITHHOLD” for each director nominee. Because this is an uncontested election where the number of nominees equals the number of directors to be elected, and the outcome of this proposal will be determined by a plurality vote, shares voted “WITHHOLD” will not prevent a director nominee from being elected as a director.have no legal effect on the outcome of the proposal. Broker non-votes will not affect the outcome of voting on this proposal.

Proposal No. 2: Ratification of Appointment PwC.of PwC. The ratification of the appointment of PwC requires the affirmative vote of a majority of the voting power of the shares present virtually or represented by proxy at the annual meeting and entitled to vote.vote on the proposal. You may vote “FOR,” “AGAINST,” or “ABSTAIN” on this proposal.

Copies of solicitation materials will also be made available upon request to brokers, banks, and other nominees to forward to the beneficial owners of the shares held of record by such brokers, banks, or other nominees. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic communication, or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse such individuals for their reasonable out-of-pocket expenses in connection with such solicitation. We do not plan to retain a proxy solicitor to assist in the solicitation of proxies.

If you choose to access the proxy materials and/or vote over the Internet, you are responsible for Internet access charges you may incur. If you choose to vote by telephone, you are responsible for telephone charges you may incur.

As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, including certain executive compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the completion of our initial public offering, (ii) the last day of the first fiscal year in which our annual gross revenue is $1.07 billion or more, (iii) the date on which we have, during the previous rolling three-year period, issued more than $1 billion in non-convertible debt securities or (iv) the date on which we are deemed to be a “large accelerated filer” as defined in the Exchange Act.

For purposes of this requirement, shares owned outright count toward these guidelines and, prior to February 2024, when the Compensation Committee modified the methodology, the calculations included the in-the-money value of vested but unexercised stock options. The value for purposes of satisfying this requirement is the 90-day trailing average of the closing price of our common stock as of the last trading day of the fiscal year prior to the compliance date. Directors have until the later of February 2025 or, if applicable, the fifth anniversary of the date they join our Board to attain the requisite level of ownership. If a director does not achieve the minimum level of ownership by the director’s compliance date, then 50% of the after-tax value of the director’s exercised options or vested restricted stock units will be retained until the minimum level of ownership for the director is met. As of December 31, 2023, all of our non-employee directors were in compliance with the stock ownership requirements under the guidelines.
Corporate Responsibility and Sustainability

BlackLine recognizes the importance of a thoughtful approach to corporate citizenship, and this is reflected in our Board's oversight of our environmental, social, and governance (“ESG”) programs. Our Nominating and Corporate Governance Committee oversees our programs relating to corporate responsibility and sustainability, including environmental, social, and corporate governance matters, and our Compensation Committee oversees our efforts to promote diversity and inclusion in our workforce, and management's efforts to foster a corporate culture in alignment with the Company's values and strategy.

During 2023, BlackLine’s ESG committee continued its work of steering and reporting on BlackLine’s ESG strategy and programs, with executive sponsorship and participation from our Chief Legal and Administrative Officer. We continue to develop our ESG strategies and practices using a stakeholder-focused approach. Our current programs include:
Community Involvement. We drive social good through our commitment to responsible corporate citizenship across the communities in which we operate. We offer employer-matched charitable giving and promote volunteer opportunities with local organizations such as the Los Angeles Regional Food Bank. Our charitable efforts are focused on three key areas that are shaped by BlackLine’s values and commitment to responsible corporate citizenship:

alleviating hunger and homelessness;

promoting STEM education, particularly among underrepresented populations; and

improving educational and professional opportunities for people in underserved communities.

Environmental Responsibility. We adopted an environmental sustainability policy in 2021, and we continue to identify strategies for reducing our environmental footprint. In 2023, our Pleasanton office achieved LEED certification, and we continue to incorporate green building standards in office design, construction and operation as part of our corporate sustainability efforts. Our sustainability initiatives in 2023 included sponsoring the planting of over 500 trees, partnering with local non-profit organizations to donate surplus office furniture and used hardware, and reducing waste by providing reusable containers and beverages on tap in select facilities.

Diversity, Equity, and Inclusion. BlackLine is committed to cultivating a workplace where each employee can be themselves and reach their full potential. Diversity, equity and inclusion (“DEI”) are deeply rooted in our culture, and we continue to support this with a company-wide objective to strengthen our DEI strategy in order to develop an agile, diverse, inclusive, and highly engaged workforce. Programs that advance our DEI strategy include employee training to reduce unconscious bias in the workplace, employee recruitment in underrepresented communities, and our employee-led and executive sponsored Employee Resource Groups, designed to help build community and foster a diverse and inclusive workplace by providing networking and team-building opportunities.

COMPENSATION OF NON-EMPLOYEE DIRECTORS

Outside Director Compensation Policy

Our board of directors adopted our Outside Director Compensation Policy in connection with our initial public offering.


Members of our board of directorsBoard who are not employees are eligible for compensation under our Outside Director Compensation Policy.

The Outside Director Compensation Policy was developed in consultation with Compensia, Inc. (“Compensia”), an independent compensation consulting firm. Compensia provided recommendations and competitive non-employee director compensation data and analyses. Our Board considered and discussed these recommendations and data, and considered the specific duties and committee responsibilities of particular directors. Our Board adopted Compensia’s recommendations when it approved our Outside Director Compensation Policy, which we believe provides our non-employee directors with reasonable and appropriate compensation that is commensurate with the services they provide and competitive with compensation paid by our peer group companies to their non-employee directors.

The Compensation Committee periodically reviews the type and form of compensation paid to our non-employee directors, which includes a market assessment and analysis by Compensia. As part of this analysis, Compensia reviews non-employee director compensation trends and data from companies comprising the same executive compensation peer group used by the Compensation Committee in connection with its review of executive compensation.

We believe that offering an employee stock purchaseBlackLine’s compensation philosophy and program, as described below in the “Compensation Discussion and Analysis” section of this proxy statement, are effective in achieving our goals, and that the executive compensation reported in this proxy statement is appropriate, competitive, and aligned with our 2023 results. The compensation program for our named executive officers is focused on pay-for-performance principles. The program is critical to our ability to maintain competitiveness. If the proposed 2018 Employee Stock Purchase Plan is not approved by the company’s stockholders, we may be restricted in our ability to offer competitive compensation to existing employees and qualified candidates, and our business and ability to increase long-term stockholder value could be adversely affected.

Description of the 2018 Employee Stock Purchase Plan

The following is a summary of the principal features of the 2018 Employee Stock Purchase Plan and its operation. However, this summary is not a complete description of all of the provisions of the 2018 Employee Stock Purchase Plan and is qualified in its entirety by the specific language of the 2018 Employee Stock Purchase Plan. A copy of the 2018 Employee Stock Purchase Plan is provided as Appendix A to this proxy statement.

Purpose. The purpose of the 2018 Employee Stock Purchase Plan is to provide our employees and employees of our subsidiaries or our affiliates (“participating subsidiaries”) with an opportunity to purchase our Shares through accumulated payroll deductions or other contributions that we may permit. The 2018 Employee Stock Purchase Plan is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended, or Section 423. In addition, the 2018 Employee Stock Purchase Plan authorizes the grant of purchase rights that do not qualify under Section 423 pursuant to rules, procedures or sub-plans adopted by our board of directors or other committee administering the 2018 Employee Stock Purchase Plan that are designed to achieve desired tax or other objectives.

Shares Available for Issuance. If our stockholders approve this proposal, a total of 1,500,000 Shares will be reserved for issuance under the 2018 Employee Stock Purchase Plan.

Plan Administration. Our board of directors or a committee appointed by our board of directors administers the 2018 Employee Stock Purchase Plan, or the Administrator. The Administrator has fullattract, motivate, and exclusive discretionary authority to construe, interpret, and apply the terms of the 2018 Employee Stock Purchase Plan, to designate separate offerings under the 2018 Employee Stock Purchase Plan, to adjudicate disputed claims under the 2018 Employee Stock Purchase Plan, and to establish such procedures that it deems necessary for the administration of the 2018 Employee Stock Purchase Plan. The Administrator is further authorized to adopt rules and procedures regarding eligibility to participate, the definition of “compensation,” handling of contributions, and making of contributions to the 2018 Employee Stock Purchase Plan, among other responsibilities.

Eligibility. All common law employees of the company, including ourretain executive officers and employees of any subsidiaries of the company that are designated by the Administrator to participate in the 2018 Employee Stock Purchase Plan, are eligible to participate in the 2018 Employee Stock Purchase Plan if they are employed by us or a participating subsidiarycompetitive market for at least 20 hours per week andexecutive talent, reward them with more than five months in any calendar

TABLE OF CONTENTS

year, or any lesser number of hours per week and/or number of months in any calendar year established by the Administrator (if required under applicable law). However, an employee may not be granted rights to purchase stock under an offering that qualifies under Section 423 of the 2018 Employee Stock Purchase Planbase salary if such employee:

immediately after the grant would own stock possessing 5% or more of the total combined voting power or value of all classes of the capital stock of the company or any subsidiary of the company; or
hold rights to purchase stock under all of our employee stock purchase plans that accrue at a rate that exceeds $25,000 worth of stock (determined at the fair market value of the stock at the time such purchase right is granted) for each calendar year in which the offering period is outstanding at any time.

Offering Periods. Our 2018 Employee Stock Purchase Plan is intended to qualify under Section 423. The 2018 Employee Stock Purchase Plan also authorizes the grant of rights to purchase Shares that do not qualify under Section 423 and such rights will be available under a separate offering from offerings intended to qualify under Section 423. Unless otherwise determined by the Administrator, each offering period under the 2018 Employee Stock Purchase Plan will have a duration of approximately 12 months, commencing on the first trading day on or after May 10 or November 10 of each year and terminating on the first trading day on or before May 10 or November 10, approximately 12 months later; provided, however, that the first offering period will commence with the first trading day on or after November 10, 2018 and will terminate on the first trading day on or before November 10, 2019. The Administrator, in its discretion, may modify the terms of offering periods before they begin, provided that no offering period may last more than 27 months. If the fair market value of a Share on an exercise date is less than the fair market value of a Share on the first trading day of the offering period, participants automatically will be withdrawn from the current offering period and will be automatically re-enrolled in a new offering period.

Each offering period will include two purchase periods, which will be approximately six months in length.

Once an employee becomes a 2018 Employee Stock Purchase Plan participant, the employee automatically will participate in each successive offering period until the employee withdraws from the 2018 Employee Stock Purchase Plan, the employee is not eligible, or the employee’s employment with the company or one of the company’s participating subsidiaries terminates, whichever occurs earlier. On the first trading day of each offering period, each participant automatically is granted a right to purchase Shares. The 2018 Employee Stock Purchase Plan purchase rights expire upon the earlier of (i) the end of the offering period, (ii) the date the participant withdraws from the 2018 Employee Stock Purchase Plan, or (iii) the date of a termination of the participant’s employment. At the end of each six-month purchase period during an offering period, the participant’s 2018 Employee Stock Purchase Plan purchase rights are exercised and the participants purchase shares based on the amount payroll deductions accumulated during such purchase period. A participant may purchase a maximum of 2,000 Shares during a purchase period. Participants may withdraw their participation at any time during an offering period and will be paid their accrued contributions that have not yet been used to purchase Shares.

Contributions. Our 2018 Employee Stock Purchase Plan permits participants to purchase Shares through payroll deductions of up to 15% of their eligible compensation, which includes base straight time gross earnings and payments for overtime and shift premium, and commissions (to the extent such commissions are an integral, recurring part of compensation), but excludes payments for incentive compensation, bonuses, equity compensation income, and other similar compensation.

Purchase Price. Shares are purchased at the end of each six-month purchase period to the extent ofBlackLine achieves challenging financial performance goals, and align the payroll deductions accumulated during such period. The purchase price ofofficers’ interests with the Shares is 85% of the lower of the fair market valueinterests of our Shares onstockholders to create long-term shareholder value, while at the first trading daysame time avoiding the encouragement of each offering period or onexcessive risk-taking.

For a more detailed discussion of our compensation philosophy, objectives, principles, and programs, we strongly encourage our stockholders to review this proxy statement, and in particular the purchase date. The Administrator may determine a different purchase price for future offering periods subject to applicable laws.

The fair market value of the Shares on any relevant date will be the closing price per share as reported on any established stock exchange or a national market system, or the mean between the high bid and low asked

TABLE OF CONTENTS

prices, if the Shares are regularly quoted by a recognized securities dealer but selling prices are not reported, in both instances, as quoted on such exchange or reported in The Wall Street Journal, or such other source the Administrator deems reliable. In the absence of an established market for the Shares, the fair market value will be determined by the Administrator.

Non-Transferability. Neither contributions credited to a participant’s account nor any rights granted under the 2018 Employee Stock Purchase Plan may be assigned, transferred, pledged, or otherwise disposed of in any way, other than by will, the laws of descent and distribution, or through a beneficiary designated under the 2018 Employee Stock Purchase Plan.

Certain Adjustments. In the event of certain changes in our corporate structure affecting our Shares, to prevent dilution or enlargement of the benefits or potential benefits available under the 2018 Employee Stock Purchase Plan, the Administrator will adjust the number and class of Shares that may be delivered under the 2018 Employee Stock Purchase Plan, the purchase price per share and the number of Shares covered by each 2018 Employee Stock Purchase Plan purchase right and the numerical share limits set forthinformation contained in the 2018 Employee Stock Purchase Plan. In“Compensation Discussion and Analysis” section below and in the eventcompensation tables and narrative that follow it in the “Executive Compensation” section of this proxy statement.

The vote on executive compensation is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our proposed liquidation or dissolution, the offering period thennamed executive officers described in progress will be shortened, and a new exercise date will be set to occur prior to the proposed transaction, unless determined otherwise by the Administrator. The Administrator will notify each participant in writing that the exercise date has been changed and that the participant’s 2018 Employee Stock Purchase Plan purchase right will be exercised automatically on the new exercise date unless prior to such date the participant has withdrawn from the offering period.

Merger or Change in Control. In the event of our merger or change in control, as defined under the 2018 Employee Stock Purchase Plan, each outstanding 2018 Employee Stock Purchase Plan purchase right will be assumed or an equivalent purchase right substituted by the successor corporation (or parent or subsidiary of the successor corporation). If the successor corporation refuses to assume or substitute for the outstanding purchase right, the offering period then in progress will be shortened, and a new exercise date will be set to occur prior to the proposed transaction. The Administrator will notify each participant that the exercise date has been changed and that the participant’s 2018 Employee Stock Purchase Plan purchase right will be exercised automatically on the new exercise date unless prior to such date the participant has withdrawn from the offering period.

Amendment; Termination. The Administrator may at any time amend, suspend, or terminate the 2018 Employee Stock Purchase Plan, including the term of any offering period then-outstanding. Generally, no such termination may adversely affect 2018 Employee Stock Purchase Plan purchase rights previously granted.

Upon its approval by the stockholders, the 2018 Employee Stock Purchase Plan will continue until the earlier to occur of (i) the termination of the 2018 Employee Stock Purchase Plan by thethis proxy statement.

Our Board or (ii) February 13, 2038 (the date which is 20 years from the adoption of the 2018 Employee Stock Purchase Plan by the Board).

U.S. Federal Income Tax Consequences

The following paragraphs are intended as a summary of the U.S. federal income tax consequences to U.S. taxpayers and the company of the purchase of Shares under the 2018 Employee Stock Purchase Plan. This summary does not attempt to describe all possible federal or other tax consequences of such participation or based on particular circumstances. In addition, it does not describe any state, local or non-U.S. tax consequences.

The 2018 Employee Stock Purchase Plan is intended to be an employee stock purchase plan within the meaning of Section 423. The 2018 Employee Stock Purchase Plan also authorizes the grant of rights to purchase Shares that do not qualify under Section 423. Under an employee stock purchase plan that qualifies under Section 423, no taxable income will be recognized by a participant, and no deductions will be allowable to the company, upon either the grant or the exercise of the purchase rights. Taxable income will not be recognized until there is a sale or other disposition of the Shares acquired under the 2018 Employee Stock Purchase Plan or in the event the participant should die while still owning the purchased Shares. No participant may purchase Shares under the 2018 Employee Stock Purchase Plan at a rate of more than $25,000 of Shares in any calendar year during which the participating employee is enrolled in that offering period.

If the participant sells or otherwise disposes of the purchased Shares within two years after the start date of the offering period in which the Shares were acquired or within one year after the actual purchase date of those Shares, then the participant generally will recognize ordinary income in the year of sale or disposition equal to

24

TABLE OF CONTENTS

the amount by which the fair market value of the Shares on the purchase date exceeded the purchase price paid for those Shares, and the company will be entitled to an income tax deduction, for the taxable year in which such disposition occurs equal in amount to such excess. The amount of this ordinary income will be added to the participant’s basis in the Shares, and any resulting gain or loss recognized upon the sale or disposition will be a capital gain or loss. If the Shares have been held for more than one year since the date of purchase, the gain or loss will be long-term.

If the participant sells or disposes of the purchased Shares more than two years after the start date of the offering period in which the Shares were acquired and more than one year after the actual purchase date of those Shares, then the participant generally will recognize ordinary income in the year of sale or disposition equal to the lesser of (i) the amount by which the fair market value of the Shares on the sale or disposition date exceeded the purchase price paid for those Shares, or (ii) 15% of the fair market value of the Shares on the start date of that offering period. Any additional gain upon the disposition will be taxed as a long-term capital gain. Alternatively, if the fair market value of the Shares on the date of the sale or disposition is less than the purchase price, there will be no ordinary income and any loss recognized will be a long-term capital loss. The company will not be entitled to an income tax deduction with respect to such disposition.

If the participant still owns the purchased Shares at the time of death, the lesser of (i) the amount by which the fair market value of the Shares on the date of death exceeds the purchase price or (ii) 15% of the fair market value of the Shares on the start date of the offering period in which those Shares were acquired will constitute ordinary income in the year of death.

Fiscal Year 2023 Compensation Highlights
2023 Executive Compensation Highlights
COMPENSATION HIGHLIGHTUNDERLYING PHILOSOPHY/CONSIDERATIONS
Co-CEO Discussion
When we made the decision to retain Ms. Tucker and Mr. Ryan as Co-CEOs, it was important to the Compensation Committee to holistically assess the compensation offered to each of them. Two key compensation principles that were used in this assessment were that we wanted to ensure that the initial equity grants made to our Co-CEOs did not exceed the level of equity grant that would have been required to hire a CEO from outside of BlackLine and we assessed the aggregate level of pay across our executive team to ensure that it was reasonable.
Stockholder Feedback
The perspective of our stockholders is an important consideration in the design of our compensation programs. In the fall of 2023, we conducted an extensive stockholder engagement program, led by our Compensation Committee chair, and have described the feedback from that program below.
Although the decisions described in this compensation discussion and analysis were made in early 2023 and therefore could not be impacted by the results of that engagement, changes resulting from stockholder feedback are described below.
Pay-for-performance alignment
We strive to maintain a pay-for-performance alignment by allocating a meaningful portion of the overall compensation opportunity for our NEOs in the form of performance-based compensation that is at risk and directly tied to specific financial objectives.
Our performance-based compensation philosophy seeks to align the interests of our NEOs to the interests of our stockholders.
32

TABLE OF CONTENTS
Alignment of performance metricswith key strategic objectives
Identifying and selecting the right performance metrics for our performance-based compensation is key to incentivizing our executives to achieve our strategic plan, which promotes the interest of our stockholders.
In 2023, our strategic focus was to grow our top-line toward profitability in a manner aligned with our long-term planning. With this in mind, we modified the performance metrics used in both our annual cash bonus plan and performance-based restricted stock unit awards (“PSUs”):
The annual cash bonus plan design was based on revenue (as in prior years) but we switched to the use of a non-GAAP operating margin metric from non-GAAP net income so that our focus on responsible growth is clear. Additionally, we determined that the portion of the annual cash bonus that we previously determined on a discretionary basis after the end of the year will instead be assessed against previously-established objectives and key results.
The shift to the use of non-GAAP operating margin was also made in our PSU awards along with revenue and annualized recurring revenue (which were also used in 2022).
We moved away from a discretionary component in our annual bonus plan whereby results were determined entirely after completion of the year to a process of establishing key financial and non-financial objectives with identified key results (OKRs) so that we can assess performance against these OKRs after the year was completed.
We understand that some investors prefer that there not be overlap between the goals for our annual bonuses and long-term equity incentive awards and considered that in our goal setting for 2023, but ultimately determined that the importance of focusing on responsible growth justified the use of the same metrics in both plans. For 2024, we moved away from the use of overlapping metrics between our annual bonus and long-term equity. The 2024 annual bonus is tied to equally-weighted metrics of revenue and non-GAAP operating margin. The 2024 PSU award is tied 50% to annualized recurring revenue (ARR) to be determined in three annual tranches and 50% to relative total shareholder return (“TSR”) measured over a three-year period.
Market-based base salary increases
We adjusted the base salaries of each of our NEOs in 2023, in each case to better align their base salaries with our competitive market and their expected contributions to our business.
Continued focus on executiverecruitment and retention
While we seek to develop our executive compensation program so that it closely aligns with our pay-for-performance philosophy and rewards achievement of performance goals, this objective must complement other important objectives, including the hiring and retention of executives.
To improve recruitment and strengthen retention, we continued our practice in 2023 of granting each NEO a portion of their annual equity awards in RSUs that vest solely over a time-based schedule and are not tied to Company performance with the remaining portion of their annual equity awards granted in PSUs as discussed below.
As described in last year’s proxy statement, in connection with retention grants made to other executives in December 2022, we made a retention grant in January 2023 for Ms. Tucker. During our stockholder engagement process, we heard clearly from some stockholders that they disfavor special retention awards and we do not intend to make any in the future without unique circumstances.
Our Compensation Philosophy
We are committed to developing a compensation program that rewards our executives in direct alignment with the achievement of both near- and long-term business and strategic objectives (i.e., pay-for-performance). In furtherance of this objective, our Compensation Committee routinely considers appropriate adjustments to the design of our compensation program to reflect our strategic direction and evolving needs of our business. Additionally, our Compensation Committee seeks to set compensation levels for our executive officers who were serving asat competitive levels so that we can attract, retain, and motivate highly

TABLE OF CONTENTS
qualified executives to contribute to our success. In assessing the overall compensation for executive officers, the Compensation Committee generally considers our financial performance, stockholder returns and position vs. selected peers, market compensation data, executive’s performance, awards given in previous years, and recommendations of our independent consultant.
When making executive compensation decisions, the Compensation Committee is guided by the following principles:
Attracting and retaining senior executives with the right expertise necessary to achieve our strategic objectives and grow our organization.
Paying for performance to ensure that a significant portion of executives’ compensation is realized when the organization meets its financial results.
Aligning interests of our executives with stockholders to ensure that executives’ compensation payouts align with the achievement of results that are correlated with long-term value and stock price appreciation.
Rewarding achievement by providing appropriate levels of awards for attaining both short-term and long-term financial results.
Our 2023 executive compensation program consisted of the following core elements:
base salary;
annual cash bonuses;
long-term equity compensation (RSUs and PSUs); and
retirement and health benefits on the same terms as for similarly situated non-executive employees.
Pay-for-Performance

Our executive compensation program is reasonable, competitive, and rigorously balances the goals of December 31, 2017.

Processattracting, motivating, rewarding, and Procedureretaining our NEOs. To ensure our NEOs’ interests are aligned with those of our stockholders and to motivate and reward individual initiative and effort, a substantial portion of their annual target total direct compensation opportunity is “at-risk” and the actual amounts payable to our NEOs will vary above or below target levels commensurate with our performance.


We emphasize performance-based compensation that appropriately rewards our NEOs for delivering financial, operational, and strategic results that meet or exceed pre-established goals through our cash bonus plan and equity awards.

Executive Compensation Decisions

Policies and Practices


We maintain sound governance standards consistent with our executive compensation policies and practices. The decisions with respectCompensation Committee evaluates our executive compensation program regularly to fiscal 2017ensure that it supports our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive officer compensation, includingtalent. These policies and practices were in effect during 2023:
What we do
Independent Compensation CommitteeAdvisor. The Compensation Committee engaged its own independent compensation consultant to assist with the design of the 2023 executive compensation program.
Annual Executive Compensation Review. The Compensation Committee conducts an annual review of compensation for our NEOs and a review of compensation-related risks.
Compensation At-Risk. The executive compensation program is designed so that a significant portion of executive annual compensation is “at risk” to align the interests of our NEOs and our stockholders. The 2023 Bonus Plan achievement for our NEOs was 42.7% of target based on the challenging goals set by the Compensation Committee and its review of our performance.
Multi-Year Vesting Requirements. The equity awards granted to our NEOs vest over multiple years and generally no portion of these awards vests until approximately 12 months after the grant date, consistent with current market practice and our retention objectives.
Limited Perquisites. We provide minimal perquisites and other personal benefits to our NEOs, except where they serve a legitimate business purpose.
Stock Ownership Guidelines. We have robust stock ownership guidelines in order to encourage stock ownership among our directors and executive officers.
Clawback policy. In 2023, our Board adopted a Compensation Recovery Policy that satisfies new Nasdaq listing standards regarding clawback policies. Our Compensation Recovery Policy provides for the recoupment of certain incentive-based compensation in the event the Company is required to restate its financial statements due to the Company’s material noncompliance with any financial reporting requirements under the securities laws.
What we don't do
No “Golden Parachute” Tax Reimbursements. We do not provide any tax reimbursement payments (including “gross-ups”) on any tax liability that our NEOs might owe as a result of the application of Sections 280G or 4999 of the Internal Revenue Code (the “Code”).
No Special Retirement Plans. We do not offer, nor do we have plans to provide, pension arrangements, retirement plans or nonqualified deferred compensation plans or arrangements exclusively to our NEOs.
No Special Health and Welfare Benefits. Our NEOs participate in the same Company-sponsored health and welfare benefits programs as our other full-time, salaried employees.
No “Single Trigger” Change of ControlArrangements. No change of control payments or benefits are triggered simply by the occurrence of a change of control. All change-of-control payments and benefits are based on a “double-trigger” arrangement (that is, they either require both a change of control of the Company plus a qualifying termination of employment before payments and benefits are paid or, in the case of certain performance awards, require a change of control of the Company and the award is not assumed in the acquisition).
No Hedging or Pledging. We have a policy that restricts employees from hedging our securities or pledging our securities as collateral.
Governance of Executive Compensation Program
Role of the Compensation Committee
The Compensation Committee discharges the responsibilities of our Board relating to the compensation of our NEOs. With respect to our NEOs, the Compensation Committee reviews and approves at the beginning of the year, or more frequently as warranted, their annual base salaries; cash bonus opportunities and cash bonus payments; long-term equity incentive

compensation; employment offers (including post-employment compensation arrangements); and other compensation, perquisites, and other personal benefits, if any.
The Compensation Committee’s practice of developing and maintaining compensation arrangements that are madecompetitive includes a balance between hiring and retaining the best possible talent and maintaining a reasonable and responsible cost structure.
Compensation-Setting Process
We do not establish a specific target for setting the target total direct compensation opportunity of our NEOs. When determining and setting the amount of each compensation element, the Compensation Committee considers the following factors:
our performance against the financial and operational objectives established by the Compensation Committee and our Board;
each individual NEO’s skills, experience, and qualifications relative to other similarly situated executives at the companies in our compensation committee, with input frompeer group;
the scope of each NEO’s role compared to other similarly situated executives at the companies in our chief executive officercompensation peer group;
the performance of each individual NEO, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or function, and chief legal and administrative officer (except work as part of a team, all of which reflect our core values;
compensation parity among our NEOs;
with respect to each of her own compensation) and Compensia, an independent compensation consultant withinNEOs other than our Co-CEOs, the meaningrecommendations of the rulesCo-CEOs; and
the compensation practices of the SECour compensation peer group and the NASDAQ Stock Market. Compensia was engaged by ourpositioning of each NEO’s compensation committee pursuant toin a ranking of peer company compensation levels.
These factors provide the authority delegated under its charter,framework for compensation decision-making and serves at the discretion offinal decisions regarding the compensation committee.

Our compensation committeeopportunities for each NEO.

Role of Management

The Compensation Committee believes each of our chief executive officer, chief financial officer,Co-CEOs, CFO, Chief People Officer, and chief legal and administrative officerCLAO has valuable insight into the day-to-day contributions of our executive officers,NEOs and solicits the advice and input from each with respect to performance objectives under our annual bonus plan. Our chief executive officer alsoIn addition, our CFO provides input with respect to the targetestablishment of metrics and targets for our annual incentive plan and our performance-based equity awards. Our Co-CEOs also provide input with respect to adjustments to annual base salaries, annual cash bonus opportunities, long-term equity incentive compensation opportunities, program structures, and other compensation-related matters for our NEOs (other than with respect to their own compensation). The Compensation Committee reviews and discusses this advice and input, along with the information, analysis and other advice it receives from its independent compensation consultant and uses them as factors in determining and approving the compensation for our NEOs. None of our officers is involved in decisions regarding their own compensation.
Role of Compensation Consultant

The Compensation Committee engages an external compensation consultant to assist it by providing information, analysis, and other advice relating to our executive compensation program and the decisions resulting from its annual executive compensation review. For 2023, the Compensation Committee retained Compensia to serve as its compensation advisor. This compensation consultant serves at the discretion of the Compensation Committee.
During 2023, Compensia regularly attended the meetings of the Compensation Committee and provided the following services:
consulting with the Compensation Committee Chair and other members between Compensation Committee meetings;
providing competitive market data based in part on the compensation peer group for our NEO positions and evaluating how the compensation we pay our NEOs compares both to our performance and to how the companies in our compensation peer group compensate their executives;

TABLE OF CONTENTS
assessing executive compensation trends within our industry, and updating on corporate governance and regulatory issues and developments;
providing competitive market data based on the compensation peer group for our Board and evaluating how the compensation we pay the non-employee members of our Board compares to how the companies in our compensation peer group compensate their boards of directors; and
reviewing market equity compensation practices, including “burn rate” and “overhang.”

In 2023, Compensia did not provide any services to us other than the consulting services provided to the Compensation Committee. The Compensation Committee regularly reviews the objectivity and independence of the advice provided by its compensation consultant on executive compensation. The Compensation Committee has considered the six specific independence factors adopted by the SEC and reflected in the listing standards of Nasdaq and determined that the work of Compensia did not raise any conflicts of interest.
Competitive Positioning

To compare our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a group of comparable technology companies. The companies in this compensation peer group were selected on the basis of their similarity to us in size and industry focus. For 2023 pay decisions, the Compensation Committee used compensation data derived from the compensation peer group as updated in August 2022. The companies in this compensation peer group were selected on the basis of their similarity to us, based on these criteria:
similar revenue size - ~0.5x to ~2.0x our last four fiscal quarter revenue of approximately $473 million (for
Q4 of 2022);
similar market capitalization - ~0.3x to ~3.0x our market capitalization of approximately $4.0 billion (around the time of the peer group review in August 2022);
similar revenue growth and market-capitalization to revenue ratio;
industry - application software, internet services and infrastructure, and systems software;
executive positions similar in breadth, complexity, and/or scope of responsibility; and
competitors for executive talent.
After consultation with Compensia, the Compensation Committee approved the following compensation peer group for 2023 compensation decisions:
AlteryxNew RelicRapid7
AppFolioPagerDutySmartsheet
AppianPaylocity HoldingSPS Commerce
Coupa SoftwareProcore TechnologiesTenable Holdings
Five9Q2 HoldingsVaronis Systems
nCinoQualysWorkiva

To analyze the executive compensation practices of the companies in our compensation peer group, Compensia gathered data from public filings. This information is supplemented with survey data from the Radford Global Compensation Survey database of companies that are similar to us in revenue, market capitalization and industry for purposes of providing additional perspective in the case of executive positions where the compensation peer group offered a limited number of relevant data points. This market data was then used as a reference point for the Compensation Committee to assess our current executive compensation levels in its deliberations on compensation forms and amounts. The market data reviewed in setting the compensation of our Co-CEOs was the average of the data shown in public filings for each peer company’s CEO and second-highest paid executive, a typical approach based on Compensia’s experience.

The Compensation Committee reviews our compensation peer group at least annually and adjusts its composition, taking into account changes in both our business and the businesses of the companies in the peer group.

Stockholder Advisory Votes on Named Executive Officer Compensation and Stockholder Engagement

Our stockholders have an opportunity to cast an advisory vote to approve (i) our NEOs’ compensation and (ii) the frequency of the vote to approve the NEOs’ compensation (“Say-on-Frequency”). We hold the advisory vote on our NEOs’ compensation annually and the Say-on-Frequency vote every six years. Our next Say-on-Frequency vote will be held in 2025. At our 2023 annual meeting, a minority of our stockholders supported our compensation practices. Our Board and Compensation Committee took this vote outcome very seriously and was highly focused on gathering and responding to stockholders’ feedback regarding our executive officers, includingcompensation practices. Accordingly, we engaged in an extensive shareholder engagement process regarding compensation in fall 2023.

In that process, we contacted stockholders representing 70% of our NEOs, other than herself. No executive officer provides input on his or her own compensation, which is determinedoutstanding shares. We engaged in 12 meetings with stockholders representing 33% of our outstanding shares (all stockholders who requested a meeting). The Company’s team at each of these meetings was led by our compensation committee, in its discretion. AtCompensation Committee Chair. In these meetings, we received important feedback from stockholders and describe below how we have acted on that feedback.

What we heardHow we responded
Longer Performance Periods. Many stockholders expressed a perspective that the one-year performance periods we have been using for our long-term incentive plan should instead measure performance over longer periods.
In our 2024 long-term equity incentive awards, a portion is now tied to our three-year performance as compared to an industry index.
More Disclosure. We heard that stockholders would like more information about how performance metrics for annual and long-term incentives are selected, and the rationale for changes.
In this proxy statement, we have provided more information regarding such reasoning and intend to continue providing this type of disclosure.
Long-term Incentive Metrics. Some stockholders expressed an interest in having long-term incentive metrics that are tied to the Company’s stock price performance over a three or more year period.
In our 2024 long-term equity incentive awards, 50% is now tied to our three-year TSR performance relative to an industry index.
Avoid Overlapping Metrics. Some investors indicated a preference that there not be overlap between the goals for our annual bonuses and long-term equity incentive awards.
The Compensation Committee considered this in our goal setting for 2023, but ultimately, given strategic and leadership transitions during the year, it determined that the importance of focusing on responsible growth justified the use of the same metrics in both plans for 2023. However, as discussed above, for 2024, we moved away from the use of overlapping metrics between our annual bonus and long-term equity.
Co-CEO Matters. Some stockholders asked for more information regarding the decision to implement a Co-CEO structure and how the Compensation Committee assessed the initial compensation arrangements for our Co-CEOs and how it will be assessed going forward.
In this proxy statement, we have provided more information on our reasoning underlying this and intend to continue providing this type of disclosure.

Individual Compensation Elements

In 2023, the request of our compensation committee, Compensia provides an assessment of the competitivenessprimary elements of our executive compensation program as compared withconsisted of base salary, an annual cash bonus opportunity, and long-term equity incentive compensation in the form of RSU and PSU awards.

Base Salary

Base salary represents the fixed portion of the compensation of our competitors,NEOs and our compensation committee uses this assessment as one of several factors in approving target levelsis an important element of compensation intended to attract and retain highly talented individuals. Generally, we establish the initial base salaries of our NEOs through arm’s-length negotiation at the time we hire the individual NEO, taking into account competitive market data, his or her position, qualifications, experience, prior salary level, and the base salaries of our other NEOs. Thereafter, the Compensation Committee reviews the base salaries of our NEOs annually and makes adjustments to base salaries as it determines to be necessary or appropriate.

The annual base salaries for our NEOs that were in effect as of the end of 2022 and 2023, respectively, are set forth below:
NEO2022 Base Salary2023 Base SalaryPercentage Increase
Therese Tucker$344,000$485,000
41.0%(1)
Owen RyanN/A$485,000N/A
Mark Partin$410,000$430,0004.9%
Karole Morgan-Prager$390,000$410,0005.1%
Mark Woodhams$400,000$412,0003.0%
(1) Ms. Tucker’s role expanded substantially from 2022 to 2023, which accounts for the increase in base salary

Annual Cash Bonus Opportunities

Each NEO participated in the 2023 Bonus Plan, which was designed to motivate our NEOs to drive “top line” growth (using a revenue goal) as well as “bottom line” profitability (using a non-GAAP operating margin goal). Additionally, 20% of the performance under the bonus plan was determined based on our performance against a set of objectives and key results that were established early in 2023 and focused on: driving responsible, profitable growth at scale; delivering valuable solutions, support, and services to the market; delivering experiences that customers value; and continuing our development of an agile, inclusive, and highly engaged workforce.

Each NEO was assigned a target annual cash bonus opportunity for 2023, representing a percentage of his or her annual base salary. In February 2023, the Compensation Committee reviewed the target annual cash bonus opportunities of our NEOs for 2023, taking into consideration a competitive market analysis prepared by Compensia, and the recommendations of our Co-CEOs (for all NEOs other than our Co-CEOs). No adjustments were made to the cash bonus opportunity for any of our NEOs.

The 2023 target annual cash bonus opportunities of the NEOs were as follows:
NEO2023 Target Annual Cash Bonus Opportunity (as a percentage of base salary)2023 Target Annual Cash Bonus Opportunity
Therese Tucker100%$485,000
Owen Ryan100%
$485,000(1)
Mark Partin70%$301,000
Karole Morgan-Prager50%$205,000
Mark Woodhams100%$412,000
(1) Mr. Ryan’s 2023 target annual cash bonus opportunity was prorated to $399,959 for his partial year of service as Co-CEO and employee of the company from March 6, 2023

Each NEO participant in the 2023 Bonus Plan was eligible to earn a payment with respect to the financial portion applicable to his or her target annual cash bonus opportunity depending on our actual performance for the year as measured against the financial performance components, and additional amounts under the discretionary component of the 2023 Bonus Plan. As described in the section “2023 Bonus Plan Performance Matrix” below, overperformance against the bonus plan components could result in payments in excess of each executive officer. Other factors our compensation committee considersNEO's target opportunity, while underperformance would result in setting executive compensation includepayments below that target opportunity, or in no payment being earned with respect to one or more components.

2023 Bonus Plan Performance Matrix

In March 2023, the Compensation Committee, with input from management, approved revenue and non-GAAP operating margin as the performance measures for the financial component under the 2023 Bonus Plan. The Compensation Committee selected these performance measures because it believed that they were appropriate drivers for our business as they provided a balance between growing our business, and managing our expenses, which enhance stockholder value over the short term.

The 2023 Bonus Plan was to be funded based on (i) the extent of our achievement against the target level of each of the following: individualfinancial metrics and (ii) the discretion exercised by the Compensation Committee under the discretionary component, all as set forth below:

_________________
*If Revenue and Non-GAAP Operating Margin achievement during 2023 is between the percentage levels identified above, then the payment percentage with respect to the applicable performance metric is calculated based on a linear interpolation between those levels (rounded to one decimal).
For purposes of the 2023 Bonus Plan, the financial performance measures had the following meanings:
Performance MeasureMeaning
Revenue“Revenue” is defined as the sum of the Company’s subscription, support, and professional services revenue; all determined under U.S. GAAP, excluding revenue from acquisitions completed during the Company’s applicable fiscal year.
Non-GAAP Operating Margin
“Non-GAAP Operating Margin” is defined as the Company’s Non-GAAP income from operations divided by its total Revenue.

“Non-GAAP income from operations” is defined as the Company’s GAAP income (loss) from operations, adjusted for: amortization of intangible assets, stock-based compensation, the change in the fair value of contingent consideration, transaction-related costs, legal settlement gains and costs, restructuring charges, impairment charges related to goodwill, impairment charges related to tangible and intangible assets, and the costs of natural disasters.

Twenty percent of our 2023 Bonus Plan target is based on progress against corporate objectives and key results (OKRs) that are focused on: driving responsible, profitable growth at scale; delivering valuable solutions, support, and services to the market; delivering experiences that customers value; and continuing our development of an agile, inclusive, and highly engaged workforce. Our corporate OKRs were established in the first quarter of 2023 and our Board and

2023 Bonus Plan Decisions

In February 2024, the Compensation Committee reviewed our overall performance for 2023, including performance against the performance measures established under the 2023 Bonus Plan. Using the 2023 Bonus Plan performance measures, the discretion it reserved under the discretionary component, the target performance, actual performance and skills, management input, internal relative alignmentweighting were as follows:
Performance MeasureTarget Performance LevelActual Performance LevelPer Measure Payment PercentageWeighted Payment Percentage
Revenue$602.8 million$589.1 million—%—%
Non-GAAP Operating Margin8.5%16.2%125%37.5%
Objectives and Key Results (OKRs)N/AN/A26%5.2%
Total42.7%

The Compensation Committee determined the payment percentage under the corporate OKRs based on positive results with respect to increasing the number of premier customers, beating our goals with respect to growth and profitability, and increasing our services revenue. On the other hand, our customer acquisition costs exceeded our targets, we slightly missed our goals with respect to downtime, and our employee engagement scores were below where we targeted.

Based on achievement of these financial performance measures and the OKRs, the 2023 Bonus Plan was funded at 42.7% of the target amount for each of our NEOs. The target annual cash bonus opportunities and the actual cash bonus payments made to the NEOs for 2023 are as follows:

(1) The target annual cash bonus opportunity for Mr. Ryan for 2023 was prorated to $399,959 for his partial year of service as Co-CEO and an employee of the Company, beginning on March 6, 2023.
Long-Term Equity Compensation

The Compensation Committee believes long-term equity compensation is an effective means for focusing our NEOs on driving increased stockholder value over a multi-year period, providing a meaningful reward for appreciation in our stock price and long-term value creation, and motivating them to remain employed with us.

Annual Long-Term Equity Awards

In February and March 2023, the Compensation Committee determined the sizes of the 2023 equity awards for our NEOs and granted equity awards to all our NEOs in the form of 50% RSU awards and 50% PSU awards. Ms Tucker’s and Mr. Ryan’s awards were determined in connection with establishing their employment arrangements as our Co-CEOs based on CEO compensation at our peer companies and in consideration of the size of an initial equity grant that would be required to hire a CEO from outside the Company.

As with their other elements of compensation, the Compensation Committee determined the amount of long-term equity incentive compensation for our other NEOs for 2023 as part of its annual compensation review and after taking into consideration a competitive market analysis, the recommendations of our Co-CEOs, each NEO’s skills, experience, and role within the organization, the outstanding equity holdings of each NEO (including the vested and unvested status of such equity holdings), the proportion of our total shares outstanding used for annual employee long-term equity compensation awards (our “burn rate”) in relation to the companies in our compensation peer group, the potential voting power dilution

Each of the RSU awards listed in the table above vests as to 25% of the shares underlying the award on February 20, 2024 and as to 1/16th of the shares underlying the award each quarter thereafter, subject to the NEO’s continued service with us through the applicable date.

Each of the PSU awards listed in the table above vests as to one-third of the shares underlying the award on each of February 20, 2024, 2025 and 2026, in each case subject to the NEO’s continued service with us through the applicable date, and in each case subject to our satisfaction of applicable performance-based conditions for the calendar year preceding the vesting date. These performance goals will be determined on an annual basis. The performance goals for vesting of the PSU awards, which were eligible to vest on February 20, 2024, were determined at the time of grant, relate to our performance in 2023, and are detailed in the section “2023 PSU Performance Matrix” below.

All of these awards are subject to additional vesting acceleration as described in the “Potential Payments Upon Termination or Change of Control” section below.

2023 PSU Performance Matrix

In February 2023, the Compensation Committee, with input from management, approved revenue, annualized recurring revenue (“ARR”), and non-GAAP operating margin as the performance measures for the portion of each of the 2022 and 2023 PSUs eligible to vest on February 20, 2024. The Compensation Committee selected these performance measures because it believed that they were appropriate drivers for our business as they provided a balance between growing our business and managing our expenses, which enhance stockholder value over the short term (as noted above, we have shifted to the use of longer performance periods in our 2024 long-term incentive awards). In all cases, the revenue and non-GAAP operating margin targets and scales were designed to ensure self-funding at every point along the curve.

The portion of the 2022 and 2023 PSUs eligible to vest on February 20, 2024 was determined to be available for vesting based on the extent of our achievement against the target level of each of the financial metrics, as set forth below:

2023 PSU Plan Performance MeasureTarget LevelWeighting
Revenue$602.8 million40%
ARR$627.2 million30%
Non-GAAP Operating Margin8.5%30%

The portion of the 2023 PSUs scheduled to vest on February 20, 2024 that is subject to the revenue metric will be available for vesting based on attainment of that performance metric as follows with the threshold performance required for our Revenue target increased from 97.5% in 2022 to 98.1% in 2023 (based on changes to our annual operating plan). Because our threshold performance requirement was higher, we made a corresponding increase in the amount earned at the threshold. The final scale for 2023 was as follows:

*If Revenue, ARR or non-GAAP operating margin achievement during 2023 is between the percentage levels anticipated futureidentified above, then the payment percentage with respect to the applicable performance metric is calculated based on a linear interpolation between those levels (rounded to the nearest hundred thousand dollars).

For purposes of the portion of the 2023 PSUs scheduled to vest on February 20, 2024, the financial performance measures had the following meanings:

Performance MeasureMeaning
Revenue“Revenue” is defined as the sum of the Company’s subscription, support, and professional services revenue; all determined under U.S. GAAP, excluding revenue from acquisitions completed during the Company’s applicable fiscal year.
ARR“ARR” is defined as contracted annualized recurring subscription and support revenue. ARR denominated in a currency other than USD shall be revalued using foreign exchange rates as of the balance sheet date for each quarterly reporting period. ARR shall exclude the impact of acquisitions completed during the Company’s applicable fiscal year.
Non-GAAP Operating Margin
“Non-GAAP Operating Margin” is defined as the Company’s Non-GAAP income from operations divided by its total Revenue.

“Non-GAAP income from operations” is defined as the Company’s GAAP income (loss) from operations, adjusted for: amortization of intangible assets, stock-based compensation, the change in the fair value of contingent consideration, transaction-related costs, legal settlement gains and costs, restructuring charges, impairment charges related to goodwill, impairment charges related to tangible and intangible assets, and the costs of natural disasters.

2023 PSU Performance Decisions

In February 2024, the Compensation Committee reviewed our overall performance for 2023, including performance against the performance measures established for 2023 under the PSU awards described above. Considering the performance measures established for those awards, the target performance, actual performance, and percent available for vesting before relative weighting were as follows:

Based on this level of achievement, the Compensation Committee determined that, with respect to the shares eligible to vest on February 20, 2024 under the 2023 PSU awards, 45% of the target amount for each of our NEOs were eligible to vest.

The numbers of shares available for vesting on February 20, 2024 under the 2023 PSUs for each of our NEOs are as follows:

Employee Benefits

Our NEOs are eligible to participate in our employee retirement benefit programs on the same basis as our other full-time, salaried employees. We sponsor a Section 401(k) profit-sharing plan, which is intended to qualify for favorable tax treatment under Section 401(a) of the Code. Our eligible U.S. employees, including the NEOs, are entitled to participate on the first day of the month following the date of hire. The Section 401(k) plan includes a salary deferral arrangement under which participants may elect to defer up to 100% of their current eligible compensation up to the statutorily prescribed limit. All participants’ interests in their deferrals are 100% vested when contributed. The Section 401(k) plan permits us to make matching contributions and profit-sharing contributions to eligible participants. In 2023, we paid discretionary matching contributions that are fully vested.

In addition, our company,NEOs are eligible to participate in our employee welfare benefit programs on the same basis as all of our employees. These benefits include medical, dental and vision benefits, disability insurance, basic life insurance coverage, health savings accounts, and accidental death and dismemberment insurance. All NEOs, except for Ms. Tucker, are also eligible to participate in our employee stock purchase plan (“ESPP”).

We design our employee benefits programs to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the judgmentcompetitive market.

Perquisites, Special Bonuses and experienceOther Personal Benefits

Currently, we do not view perquisites, special bonuses, or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites, special bonuses, or other personal benefits to our NEOs, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our NEOs more efficient and effective, and for recruitment and retention purposes.
Employment Arrangements

We have entered into written employment offer letters with each of our NEOs, other than Ms. Tucker and Mr. Ryan, and an employment agreement with each of Ms. Tucker and Mr. Ryan. Each of these employment arrangements was approved on our behalf by the Compensation Committee or, in certain instances, by our Board. Each of these employment arrangements provides for “at will” employment and set forth the compensation arrangements for the NEO, including base salary and an annual cash bonus opportunity.

TABLE OF CONTENTS

On March 5, 2023, in connection with Ms. Tucker’s transition to become Co-CEO, we entered into an employment agreement with Ms. Tucker, which supersedes her prior employment agreement. We entered into an employment agreement with Mr. Ryan at the same time on substantially the same terms. In connection with this transition, the Compensation Committee approved an increase to Ms. Tucker’s base salary in connection with her transition from Executive Chair to Co-CEO. In determining this adjustment, the Compensation Committee considered the substantial increase in Ms. Tucker’s duties and responsibilities as a result of this transition, and took into account a competitive market data analysis provided by Compensia.

In filling each of our executive positions, our Board or the Compensation Committee, as applicable, recognized that it would need to develop competitive compensation packages to attract qualified candidates in a dynamic labor market. At the same time, our Board and the Compensation Committee were sensitive to the need to integrate new executive officers into the executive compensation structure that we were seeking to develop, balancing both competitive and internal equity considerations.

For information on the specific terms and conditions of the employment arrangements of the NEOs, see the discussion of “Executive Employment Arrangements” below.
Post-Employment Compensation

We entered into written participation agreements under our Change of Control and Severance Policy (the “Policy”) with each of our NEOs (other than Ms. Tucker and Mr. Ryan) and a written employment agreement with Ms. Tucker and Mr. Ryan, providing for change of control and severance payments and benefits.

On March 5, 2023, in connection with Ms. Tucker’s transition to become Co-CEO, we entered into an employment agreement providing for post-employment compensation with Ms. Tucker, which supersedes her prior employment agreement.

On March 5, 2023, in connection with Mr. Ryan’s transition to become Co-CEO, we entered into an employment agreement providing for post-employment compensation with Mr. Ryan.

We believe that having in place reasonable and competitive post-employment compensation arrangements is essential to attracting and retaining highly qualified executive officers. Our post-employment compensation arrangements are designed to provide reasonable compensation to executive officers who leave our Company under certain circumstances to facilitate their transition to new employment. Further, we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing executive officer to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits.

We do not consider specific amounts payable under these post-employment compensation arrangements when establishing annual compensation. We do believe, however, that these arrangements are necessary to offer compensation packages that are competitive.

We believe that these arrangements are designed to align the interests of management and stockholders when considering the long-term future for the Company. The primary purpose of these arrangements is to keep our most senior executive officers focused on pursuing all corporate transaction activity that is in the best interests of stockholders regardless of whether those transactions may result in their own job loss. Reasonable post-acquisition payments and benefits should serve the interests of both the executive and our investors.

All payments and benefits in the event of a change of control of the Company are payable only if there is a subsequent loss of employment by an executive officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention power following a change of control and to avoid windfalls, both of which could occur if vesting accelerated automatically as a result of the transaction.

We do not use excise tax payments (or “gross-ups”) relating to a change of control of the Company and have no such obligations in place with respect to any of our NEOs.

For information on the change of control and severance agreements for the NEOs, as well as an estimate of the potential payments and benefits payable under these agreements as of the end of 2023, see “Executive Employment Arrangements” and “Potential Payments Upon Termination or Change of Control” below.

Other Compensation Policies and Practices
Policy Prohibiting Hedging or Pledging of Our Equity Securities

Our Insider Trading Compliance Policy prohibits all our employees, including our NEOs, and the members of our compensation committee.

Our compensation committee makes the final decisionsBoard from engaging in derivative securities transactions, including hedging, with respect to allour common stock and from pledging our securities as collateral or holding our securities in a margin account.

Executive Stock Ownership Guidelines

In February 2020, the Compensation Committee and the Nominating and Corporate Governance Committee recommended, and our Board approved, stock ownership guidelines for our executive officers. Under these guidelines, each executive officer is expected to attain minimum levels of stock ownership equal to 1x (or 5x, in the case of our Co-CEOs) the executive officer’s annual base salary. For purposes of this requirement, shares owned outright count toward these guidelines and, prior to February 2024, when the Compensation Committee modified the methodology, the calculations included the in-the-money value of vested but unexercised stock options. The value for purposes of satisfying this requirement is the 90-day trailing average of the closing price of our common stock as of the last trading day of the fiscal year prior to the compliance date. Executive officers have a phase-in period that lasts until the later of February 2025 or, if applicable, the fifth anniversary of the date they become an executive officer or are appointed to their position to comply with these guidelines. If an executive officer does not achieve the minimum level of ownership by the executive officer’s compliance date, then 50% of the after-tax value of the executive officer’s exercised options or vested RSUs will be retained until the minimum level of ownership for the executive officer is met. As of December 31, 2023, all of our executive officers were in compliance with the stock ownership requirements under the guidelines.
Tax and Accounting Considerations
Deductibility of Executive Compensation

Section 162(m) of the Code generally limits the amount we may deduct from our federal income taxes for compensation decisions.

paid to our CEO and certain other current and former executive officers that are “covered employees” within the meaning of Section 162(m) of the Code to $1 million per individual per year, subject to certain exceptions. The regulations promulgated under Section 162(m) of the Code contain a transition rule that applies to companies, such as ours, that become subject to Section 162(m) of the Code by reason of becoming publicly held. Pursuant to this rule, certain compensation granted during a transition period (which ended on the 2020 annual meeting for us) currently is not counted toward the deduction limitations of Section 162(m) of the Code if the compensation is paid under a compensation arrangement that was in existence before the effective date of the initial public offering and certain other requirements are met. While certain of our equity awards may be eligible to be excluded from our deductibility limitation of Section 162(m) of the Code pursuant to this transition rule, the Compensation Committee has not adopted a policy that all equity or other compensation must be deductible.


In approving the amount and form of compensation for our NEOs, the Compensation Committee generally considers all elements of the cost to us of providing such compensation, including the potential impact of Section 162(m) of the Code, as well as our need to maintain flexibility in compensating executive officers in a manner designed to promote our goals. The Compensation Committee may, in its judgment, authorize compensation payments that may or may not be deductible when it believes that such payments are appropriate to attract, retain or motivate executive talent.
Accounting for Stock-Based Compensation

We follow the Financial Accounting Standard Board’s Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”) for our stock-based compensation awards. FASB ASC Topic 718 requires us to measure the compensation expense for all share-based payment awards made to our employees and members of our Board, including options to purchase shares of our common stock and other stock awards, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the executive compensation tables required by the federal securities laws, even though the recipient of the awards may never realize any value from their awards.
Risk Considerations

The Compensation Committee, in cooperation with management, reviewed our 2023 compensation programs. Our Compensation Committee believes that the mix and design of the elements of such programs do not encourage our employees to assume excessive risks and accordingly are not reasonably likely to have a material adverse effect on our Company. We have designed our compensation programs to be balanced so that our employees are focused on both short and long-term financial and operational performance. In particular, the weighting towards long-term equity incentive compensation discourages short-

term risk taking. Goals are appropriately set with targets that encourage growth in the business, while doing so in a manner that encourages profitability.
Executive Employment Arrangements
Therese Tucker. On March 5, 2023, in connection with Ms. Tucker’s transition to Co-CEO, effective as of March 6, 2023, we entered into an employment agreement with Ms. Tucker, which supersedes her prior employment agreement. Under this new employment agreement (the “Tucker Employment Agreement”), as Co-CEO, Ms. Tucker will earn an annual base salary of $485,000 and have a target bonus of 100% of her salary. The Tucker Employment Agreement also provided for equity awards that have been granted with a value of $10,000,000, which were made up of 50% RSUs that will vest over four years, subject to Ms. Tucker’s continued full-time employment, and 50% PSUs that will vest on the same performance terms as awards granted to our other executives in 2023, as determined by the Compensation Committee.

The Tucker Employment Agreement provides that if her employment is terminated by us without “cause” (as such term is defined in the Tucker Employment Agreement) other than for death or disability, outside of the period beginning 3 months prior to a “change of control” (as such term is defined in the Tucker Employment Agreement) and ending 12 months following the change of control, Ms. Tucker will be eligible to receive: (i) a lump sum cash payment equal to 100% of her annual salary and (ii) reimbursement by the Company for COBRA premiums Ms. Tucker pays to maintain group health insurance benefits for herself and her dependents under COBRA for up to 12 months following the date of termination.

The Tucker Employment Agreement also provides that if her employment is terminated by us during the period beginning 3 months prior to a change of control and ending 12 months following the change of control without cause other than for death or disability or she resigns for “good reason” (as defined in the Tucker Employment Agreement), then she will be eligible to receive (i) a lump sum cash payment equal to 150% of her annual salary, (ii) a lump sum cash payment equal to a prorated portion of her target annual bonus for the year of termination and (iii) reimbursement by the Company for COBRA premiums she pays to maintain group health insurance benefits for herself and her dependents under COBRA for up to 18 months following the termination date, and (iv) 100% of all of her outstanding equity awards will become vested and fully exercisable effective as of the later of the date of termination or the date of the consummation of the change of control (and with respect to any Company performance-based equity awards, for which the applicable performance period has (x) been completed as of her termination date, based on actual achievement of the applicable performance objectives or (y) not been completed as of her termination date, assuming achievement of the applicable performance objectives at target).

Owen Ryan. On March 5, 2023, in connection with Mr. Ryan’s transition to Co-CEO, effective as of March 6, 2023, we entered into an employment agreement on the same terms described above with respect to the Tucker Employment Agreement.

Mark Partin. We entered into an employment letter with Mr. Partin. The employment letter has no specific term and provides for “at-will” employment. As of December 31, 2022, Mr. Partin’s annual base salary was $410,000 and his annual on-target bonus opportunity was 70% of his annual base salary.

Karole Morgan-Prager. We entered into an employment letter with Ms. Morgan-Prager. The employment letter has no specific term and provides for “at-will” employment. As of December 31, 2022, Ms. Morgan-Prager’s annual base salary was $390,000 and her annual on-target bonus opportunity was 50% of her annual base salary.

Mark Woodhams. We entered into an employment letter with Mr. Woodhams. The employment letter has no specific term and provides for “at-will” employment. As of December 31, 2022, Mr. Woodhams' annual base salary was $400,000 and his annual on-target bonus opportunity was 100% of his annual base salary.

Marc Huffman Separation Arrangements

Effective March 2023, the Company entered into a separation agreement and release with Mr. Huffman in connection with his separation from the Company. In accordance with Mr. Huffman’s existing rights under the terms of his participation agreement under the Company’s change of control and severance policy for a termination without cause, the separation agreement provided for payment of 12 months of salary and continuation of benefits for 12 months, as well as accrued compensation through the date of his departure. In addition, to ensure a successful transition, Mr. Huffman agreed to provide certain consulting services for 12 months following the end of his employment with the Company during which time his time-based equity awards continued to vest based on the original terms of such awards and he was paid $80,000 in consulting fees. Mr. Huffman forfeited all other outstanding equity awards he held, including the retention award granted to him in December 2022.

(1)The amounts in these columns
(1)The amounts in this column represent the aggregate grant date fair value of stock option awards as computed in accordance with Financial Accounting Standard Board Accounting Standards Codification Topic 718, or ASC 718. The assumptions used in calculating the grant date fair value of the awards reported in this column are set forth in Note 2 to our financial statements appearing at the end of our Annual Report on Form 10-K for the year ended December 31, 2017. As required by SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. With respect to Ms. Tucker’s performance-based option to purchase 482,800 shares of our common stock, or the Performance-Based Option, although the award has been legally granted, as of December 31, 2017, we could not determine that the achievement of the performance targets is probable. This is due to the fact that the vesting is based, in part, on the achievement of yearly cash flow targets through 2019 that have yet to be established. The cash flow targets for each year are determined by our board of directors concurrently with the annual budget process and because each yearly cash flow target has not yet been set, there is no grant date and therefore no grant date fair value. Accordingly, the award has not been included in the table. If each yearly cash flow target is met through 2019, but the full cumulative annual recurring target through 2019 is not met, Ms. Tucker is still able to vest in the award if an additional cash flow target for 2020 and a cumulative annual

recurring revenue target through 2020 are achieved. If the Performance-Based Option was valued as though the date of legal grant was also the accounting grant date, assuming 100% achievement of all performance-based targets, the Performance-Based Option would have a grant date fair value of $3,176,824.

(1)Amounts in the “Estimated Future Payouts Under Non-Equity Incentive Plan Compensation

Each ofAwards” columns relate to cash incentive compensation opportunities under our NEOs participated2023 Bonus Plan, as described in the 2017section titled “Executive Compensation—Compensation Discussion and Analysis—Individual Compensation Elements – 2023 Bonus Plan which providedPerformance Matrix” and “—2023 Bonus Plan Decisions.” Mr. Ryan’s target opportunity under our 2023 Bonus Plan award was prorated from $485,000 for cash incentives for certain company executives, including our NEOs, for 2017 performance. Target bonuses forhis partial year of service as Co-CEO and an employee beginning on March 6, 2023.

(2)The amount in this column represents the NEOs wereaggregate grant date fair value of stock awards as computed in accordance with Financial Accounting Standard Board Accounting Standards Codification Topic 718, or ASC 718. The fair value of the PSUs is calculated based on a percentage of his or her 2017 annual base salary as follows: Ms. Tucker (100%), Mr. Partin (50%), and Mr. Murphy (100%).

target shares. The 2017 Bonus Plan was designed to fund based on company performance, measured by gross annual recurring revenue bookings less churned (lost) annual recurring revenue, or Net New ARR, and free cash flow. The 2017 Bonus Plan provides that ifassumptions used in calculating the free cash flow threshold was achieved, then the 2017 Bonus Plan would fund as to: (a) 50%, if between 80% and 84.99%grant date fair value of the Net New ARR target was achieved, (b) 62.5%, if between 85% and 89.99% of the Net New ARR target was achieved, (c) 75%, if between 90% and 94.99% of the Net New ARR target was achieved, (d) 87.5%, if between 95% and 99.99% of the Net New ARR target was achieved, or (e) 100%, if 100% or above of the Net New ARR target was achieved. To the extent the Net New ARR achievement was between applicable percentages, the funding percentage would be funded based on a linear interpolation between those levels. Each NEO’s bonus payment under the 2017 Bonus Plan was based on the percentage at which the 2017 Bonus Plan funded as described above. The Net New ARR target was based on the targeted growth of Net New ARR from the end of the year 2016 to the end of the year 2017 and the free cash flow threshold was based on cash flow from operations less capital expenditures for 2017. Our compensation committee administers the 2017 Bonus Plan, and reserved the discretion to modify or change the formula for paying bonuses.

After the end of 2017, our compensation committee determined that we achieved the free cash flow threshold, but did not achieve any Net New ARR threshold under the 2017 Bonus Plan. However, after consideration of the achievements we made during 2017 with respect to our overall financial performance and the scaling of our operations and of each NEO’s contributions to those achievements, our compensation committee exercised its discretion under the 2017 Bonus Plan to award bonuses under the 2017 Bonus Planawards reported in the amountsthis column are set forth in Note 2 to our financial statements in our Annual Report on Form 10-K for the “Non-Equity Incentive Plan Compensation” columnyear ended December 31, 2023.

CEO Equity Awards

Ms. Tucker received two stock option awards in 2016.

Performance-Based Option. The first stock option award is the Performance-Based Option covering 482,800 shares of our common stock. The shares subject to the Performance-Based Option vest based on achievement of certain performance metrics and Ms. Tucker’s continued service with us through the date on which achievement is determined by our board of directors or its authorized committee. For the period beginning on January 1, 2016 and ending on December 31, 2019, or the Performance Period, if we achieve yearly cash flow targets as determined by our board of directors concurrently with the annual budget process for each of our fiscal years, or the Cash Flow Metric, then the Performance-Based Option vests based on the extent of our achievement of cumulative annual recurring revenue targets during the Performance Period. If our board of directors determines that the Cash Flow Metric was met during the Performance Period but we did not achieve the full cumulative annual recurring revenue targets during the Performance Period, then the portion of the Performance-Based Option that becomes eligible to vest and become exercisable but failed to vest during the Performance Period may be eligible to vest and becomes exercisable based on the extent of our achievement of an additional cash flow target for 2020 and a cumulative annual recurring revenue target during the period beginning on January 1, 2016 and ending on December 31, 2020.

If, upon a “change of control” (as defined in Ms. Tucker’s employment agreement), the Performance-Based Option is not vested and exercisable and is not assumed or substituted for, then it is intended that, immediately prior to such change of control, the Performance-Based Option will vest as to 100% of the shares subject to the Performance-Based Option. If, upon a change of control, the Performance-Based Option is assumed and substituted for and cumulative annual recurring revenue thresholds are met (which are based on the year in which the change of control occurs), then, immediately prior to the change of control, the Performance-Based Option will vest and become exercisable as to the number of shares subject to the Performance-Based Option equal to 1/48th of the number of shares subject to the Performance-Based Option multiplied by the total number of completed months between the date the Performance-Based Option is granted and the consummation of the change of control, rounded down to the nearest whole share, and the remaining shares will become vested and exercisable at a rate of 1/48th of the number of shares subject to the Performance-Based Option per month through the four year anniversary of the date the Performance-Based Option is granted, subject to Ms. Tucker’s continued service with us through each such vesting date.

Time-Based Option. The second stock option award is the Time-Based Option covering 96,560 shares of our common stock. 25% of the shares subject to the Time-Based Option (rounded down to the nearest whole number of shares) will vest on each of the first four anniversaries of the Time-Based Option’s vesting commencement date (January 20, 2015), subject to Ms. Tucker’s continued service with us through each suchapplicable vesting date.

(1)A qualifying termination of employment is considered “in connection with a change of control” if such termination occurs within the period commencing on (or three (3) months before for Ms. Tucker or Mr. Ryan) and ending twelve (12) months after a “change of control”.
(2)These estimates of cash severance payable to Ms. Tucker and Mr. Ryan include: for a qualifying termination not in connection with a change in control, lump sum payments of twelve (12) months of base salary and COBRA premium costs; and for a qualifying termination in connection with a change of control, lump sum payment of eighteen (18) months of base salary and COBRA premium costs and prorated portion of the executive’s target annual bonus for the year of termination.
(3)These estimates of continued coverage reflect the present value of monthly COBRA premium payments for the applicable severance period.
(4)For purposes of valuing accelerated vesting, the values indicated in the table are calculated, with respect to stock options, as the aggregate difference between $62.44, the closing price of a share of our common stock on December 29, 2023 (the last trading day of 2023), and the exercise price of the applicable option, multiplied by the number of unvested shares accelerated, with respect to RSUs, $62.44 multiplied by the number of unvested RSUs accelerated, and, with respect to PSUs, $62.44 multiplied by the number of PSUs for which performance conditions would be satisfied, or for which time-based vesting requirements would be accelerated.
(5)These estimates of accelerated equity vesting for Ms. Tucker and Mr. Ryan include: for a qualifying termination in connection with a change of control, acceleration of one hundred percent (100%) of the executive’s then-outstanding equity awards.
(6)These estimates of cash severance payable to Mr. Partin, Ms. Morgan-Prager and Mr. Woodhams include: for a qualifying termination not in connection with a change of control, a lump sum payment of 6 months of base salary; and for a qualifying termination in connection with a change of control, a lump sum payment of twelve (12) months of base salary.
(7)These estimates of accelerated equity vesting for Mr. Partin, Ms. Morgan-Prager and Mr. Woodhams include: for termination upon a qualifying termination in connection with a change of control, acceleration of one hundred percent (100%) of the executive’s then-outstanding and unvested equity awards granted in 2020 through 2022 or in connection with his or her hiring or promotion, as applicable.
Therese Tucker. On August 24, 2016, weTucker and Owen Ryan
We entered into an employment agreement with Therese Tucker, our Chief Executive Officer. The employment agreement has an initial term of three years from January 1, 2016 and is expected to automatically renew on each year thereafter, unless we or Ms. Tucker provides the other party at least 30 days written notice. In the event of a “change in control” (as defined in Ms. Tucker’s agreement), the term will extend for an additional two years from the date of such change in control.

The employment agreement provides Ms. Tucker with an initial annual base salary of $350,000 and an on-target bonus equal to 100% of her base salary, based upon achievement of performance objectives to be determined by our compensation committee.

Ms. Tucker’s employment agreement also provides that if her employment is terminated by us without “cause” (excluding by death or disability), we decide to not renew Ms. Tucker’s agreement, or Ms. Tucker resigns for “good reason” (as such terms are defined in Ms. Tucker’s agreement), Ms. Tucker will receive (i) a lump sum payment equal to 18 months of Ms. Tucker’s base salary then in effect; (ii) a lump sum payment equal to the premium costs for Ms. Tucker and her eligible dependents to continue health insurance coverage under COBRAMr. Ryan that provide for 18 months; (iii) a lump sum amount equal to the prorated portion of Ms. Tucker’s annual bonus for the year of termination that would have been paid to Ms. Tucker had Ms. Tucker been employed by us for the entire fiscal year of termination, based on actual performance for the year (and assuming any individual performance goals would have been met at target levels); and (iv) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any.

Ms. Tucker’s employment agreement also provides that if Ms. Tucker’s employment is terminated by us without “cause” (excluding by death or disability), we decide to not renew Ms. Tucker’s agreement, or Ms. Tucker resigns for “good reason” and such termination occurs in connection with, or within three months before or 24 months after a “change of control” (as such term is expected to be defined in Ms. Tucker’s agreement), Ms. Tucker will receive (i) a lump sum payment equal to 12 months of Ms. Tucker’s base salary then in effect, or, if greater, as in effect immediately prior to the change of control; (ii) a lump sum payment equal to the premium costs for Ms. Tucker and her eligible dependents to continue health insurance coverage under COBRA for 12 months; (iii) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any; and (iv) 100% of the shares subject to Ms. Tucker’s outstanding Company equity awards will vest and, to the extent applicable, become exercisable.

Ms. Tucker’s employment agreement also provides that if her employment is terminated due to her death or disability, Ms. Tucker will receive (i) a lump sum amount equal to the earned but unpaid bonus for the prior fiscal year, if any and (ii) a lump sum amount equal to the Ms. Tucker’s target bonus, pro-rated to reflect time served in the year of termination.

Any receipt of severance benefits by Ms. Tucker will be contingent upon her execution and non-revocation of a separation agreement and release of claims against us. In the event any of the payments provided for under Ms. Tucker’s employment agreement or otherwise payable to Ms. Tucker would constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, or the Code, could be subject to the related excise tax under Section 4999 of the Code, she would be entitled to receive either full payment of benefits or such lesser amount which would result in no portion of the benefits being subject to the excise tax, whichever results in the greater amount of after-tax benefits to her. Ms. Tucker’s employment agreement does not require us to provide any tax gross-up payments.

Mark Partin. On September 29, 2016, we entered into a confirmatory employment letter with Mr. Partin. The confirmatory employment letter has no specific term and provides for at-will employment. The confirmatory employment letter supersedes Mr. Partin’s original employment offer letter. The vesting accelerationcontrol and severance benefits have been replaced by the Policy as describedunder certain circumstances. See “Executive Employment Arrangements—Therese Tucker” and “Executive Employment Arrangements—Owen Ryan” for further details.

A lump sum cash amount equal to six monthsone year of the executive officer’s base salary in effect immediately prior to the termination (or if the termination is due to a resignation for good reason based on a material reduction in base salary, then the executive officer’s annual base salary in effect immediately prior to such reduction) or the change of control, whichever is greater; and
Payment or reimbursement of continued health coverage for the executive officer and the executive officer’s eligible dependents under COBRA for a period of up to 12 months or a taxable lump sum payment in lieu of payment or reimbursement, as applicable.

Our 2016 Plan provides that on the first day of each fiscal year beginning with the 2017 fiscal year, the number of shares of our common stock available for issuance thereunder will be increased in an amount equal to the least of (i) 6,196,000 shares, (ii) 5% of the total number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year or (iii) a lower number of shares determined by our Board or a committee thereof. On January 1, 2024, the number of shares of our common stock reserved for issuance under our 2016 plan increased by 3,075,755 shares pursuant to this provision. This increase is not reflected in the table above.
CEO Pay Ratio

Under rules adopted pursuant to the Dodd-Frank Act, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer (the “CEO Pay Ratio”). The paragraphs that follow describe our methodology and the resulting CEO Pay Ratio.

Measurement Date

We identified the median employee using our employee population on November 1, 2023 (including all employees, whether employed on a full-time, part-time, seasonal or temporary basis).

Consistently Applied Compensation Measure (CACM)

Under the relevant rules, we are required to identify the median employee by use of a “consistently applied compensation measure,” or CACM. We chose a CACM that closely approximates the annual target total direct compensation of our employees. Specifically, we identified the median employee by aggregating, for each employee: a) annual base pay, b) annual target cash incentive opportunity, and c) the estimated grant date fair value for equity awards granted as of November 1, 2023. In identifying the median employee, we converted compensation amounts paid in foreign currencies based on the applicable year-to-date average exchange rate as of November 1, 2023, and annualized the compensation values of individuals that joined our Company during 2023. We did not exclude workers in non-U.S. countries and did not make any cost-of-living adjustments.

Methodology and Pay Ratio

After applying our CACM methodology, we identified a median employee with anomalous compensation characteristics. Therefore, we substituted an employee near the median whose compensation was viewed as more representative of our median employee. Once the median employee was identified, we calculated the median employee’s annual target total direct compensation in accordance with the requirements of the Summary Compensation Table.

Our median employee compensation as calculated using Summary Compensation Table requirements was $174,313. Our Co-Chief Executive Officer, Therese Tucker’s, compensation as reported in the Summary Compensation Table was $8,527,312. Therefore, her CEO Pay Ratio for 2023 is approximately 49 to 1. Our Co-Chief Executive Officer, Owen Ryan’s, compensation
56

TABLE OF CONTENTS
as reported in the Summary Compensation Table was $6,841,068. Therefore, his CEO Pay Ratio for 2023 is approximately 39 to 1.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the Compensation Committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.

TABLE OF CONTENTS

Description of Relationships Between Compensation Actually Paid and Performance


Compensation Actually Paid, as determined under rules adopted pursuant to the Dodd-Frank Act and reflected in the Pay Versus Performance table above (“CAP”) for our CEOs was lower than Summary Compensation Table Total compensation in 2023, aligning with the decrease in cumulative TSR over the period. Average NEO CAP reflected similar alignment, falling below Summary Compensation Table values. This pattern is also seen in prior years, reflecting the alignment of CEO and NEO compensation with shareholder returns.

In 2023, our TSR underperformed the TSR of the S&P 500 Software & Services Select Index.Over the four-year period covered by this disclosure, both our TSR and our peer group TSR remain positive, reflecting the value provided to shareholders.

Our net income was positive in 2023, reflecting a shift from the years 2020 – 2022. Despite this increase, CAP was lower than in prior years. This reflects a change from the directional alignment of our CEO CAP and average NEO CAP with net income from 2020 - 2022.

Our revenue increased each year from 2020 to 2023. These increases are not directionally aligned with overall decreases in our CEO CAP and average NEO CAP from 2020 to 2023, but are directionally aligned with increases in our CEO CAP and average NEO CAP from 2021 to 2022.

(c)Limitations.

A-5

TABLE OF CONTENTS

Contributions made on such day applied to his or her account under the then-current Purchase Period or Offering Period). The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

(b)In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on or prior to the last pay day prior to the Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10 hereof.
(c)All Contributions made for a Participant will be credited to his or her account under the Plan and Contributions will be made in whole percentages of his or her Compensation only. A Participant may not make any additional payments into such account.
(d)A Participant may discontinue his or her participation in the Plan as provided in Section 10. Unless otherwise provided by the Administrator, during any Purchase Period, a Participant may decrease (but not increase) the rate of his or her Contributions (including to zero percent (0%)) one (1) time by satisfying the procedures set forth in this paragraph, provided that any change in Contribution rate made pursuant to the immediately preceding sentence will be effective as of the first full payroll period following five (5) business days after the date on which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in Contribution rate earlier). Any change to the rate of Participant’s Contributions during a Purchase Period to the extent permitted under this paragraph will require the Participant to (i) properly complete and submit to the Company’s stock administration office (or its designee) a new subscription agreement authorizing the change in Contribution rate in the form provided by the Administrator for such purpose, or (ii) follow an electronic or other procedure prescribed by the Administrator, in either case, on or before a date determined by the Administrator. If a Participant has not followed the procedures set forth in this Section 6(d) to change the rate of Contributions, the rate of his or her Contributions will continue at the originally elected rate throughout the Purchase Period and Offering Period and future Purchase Periods and Offering Periods (unless the Participant’s participation is terminated as provided in Sections 10 or 11). The Administrator may, in its sole discretion, limit or amend the nature and/or number of Contribution rate changes that may be made by Participants during any Purchase Period or Offering Period, and may establish such other conditions or limitations as it deems appropriate for Plan administration.
(e)Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(c), a Participant’s Contributions may be decreased to zero percent (0%) by the Administrator at any time during an Offering Period (or Purchase Period, as applicable). Subject to Section 423(b)(8) of the Code and Section 3(c) hereof, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Offering Period (or Purchase Period, as applicable) scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10.
(f)Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Participants to participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted or advisable under Applicable Law, (ii) the Administrator determines that cash contributions are permissible for Participants participating in the 423 Component and/or (iii) the Participants are participating in the Non-423 Component.

In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423 2(f).

On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than 2,000 shares of Common Stock (subject to any adjustment pursuant to Section 18) and provided further that such purchase will be subject to the limitations set forth in Sections 3(c) and 13 and in the subscription agreement. The Eligible Employee may accept the grant of such option by electing to participate in the Planvoted in accordance with the requirementsBoard of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period of an Offering Period.

8.    Exercise of Option.

(a)Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date,Directors' recommendations. Continued and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the Participant’s account for the subsequent Purchase Period or Offering Period, as applicable, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant. During a Participant’s lifetime, a Participant’s option to purchase shares of Common Stock hereunder is exercisable only by him or her.
(b)If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 19.

9.    Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a trustee or designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares of Common Stock be retained with such broker, trustee, or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions or other dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided in this Section 9.

10.    Withdrawal.

(a)A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or her option under the Plan by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose (which may be similar to the form attached hereto as Exhibit B), or (ii)following an electronic or other withdrawal procedure determined by the Administrator. For a withdrawal to be effective, a Participant must follow the procedures set forth in this Section 10(a) prior to 1pm Pacific Time on the business day prior to an Exercise Date. If the withdrawal does not occur prior to this time, the Participant will continue to be a Participant in the Plan. All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5.
(b)A Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws.

11.    Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee for any reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto, and such Participant’s option will be automatically terminated. Unless determined otherwise by the Administrator in a manner that, with respect to an Offering under the 423 Component, is permitted by, and compliant with, Section 423 of the Code, a Participant whose employment transfers between entities through a termination with an immediate rehire (with no break in service) by the Company or a Designated Company will not be treated as terminated under the Plan; however, if a Participant transfers from an Offering under the 423 Component to the Non-423 Component, the exercise of the option will be qualified under the 423 Component only to the extent it complies with Section 423 of the Code.

12.    Interest. No interest will accruesigned on the Contributions of a participant in the Plan, except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall, with respect to Offerings under the 423 Component, apply to all Participants in the relevant Offering, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423 2(f).

13.    Stock.

(a)Subject to adjustment upon changes in capitalization of the Company as provided in Section 18 hereof, the maximum number of shares of Common Stock that will be made available for sale under the Plan will be 1,500,000 shares of Common Stock.

TABLE OF CONTENTS

(b)Until the shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will have only the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.
(c)Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the Participant or, if so required under Applicable Law, in the name of the Participant and his or her spouse.

14.    Administration. The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to delegate ministerial duties to any of the Company’s employees, to designate separate Offerings under the Plan, to designate Subsidiaries and Affiliates as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary or advisable for the administration of the Plan (including, without limitation, to adopt such procedures, sub-plans, and appendices to the enrollment agreement as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans and appendices may take precedence over other provisions of this Plan, with the exception of Section 13(a) hereof, but unless otherwise superseded by the terms of such sub-plan or appendix, the provisions of this Plan shall govern the operation of such sub-plan or appendix). Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate Offering under the 423 Component, or if the terms would not qualify under the 423 Component, in the Non-423 Component, in either case unless such designation would cause the 423 Component to violate the requirements of Section 423 of the Code. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. 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 an option 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 options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.

15.    Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

16.    Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party, provided that, if such segregation or deposit with an independent third party is required by Applicable Laws, it will apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423 2(f). Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

17.    Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

18.    Adjustments, Dissolution, Liquidation, Merger or Change in Control.

(a)Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share, class, and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13.
(b)Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.
(c)Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

19.    Amendment or Termination.

(a)The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 18). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12 hereof) as soon as administratively practicable.
(b)Without stockholder consent and without limiting Section 19(a), the Administrator will be entitled to change the Offering Periods and any Purchase Periods, designate separate Offerings, 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 Contributions 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 Contribution elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with the Plan.

A-10

TABLE OF CONTENTS

(c)In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:
(i)amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;
(ii)altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the time of the change in Purchase Price;
(iii)shortening any Offering Period or Purchase Period by setting a New Exercise Date, including an Offering Period or Purchase Period underway at the time of the Administrator action;
(iv)reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and
(v)reducing the maximum number of shares of Common Stock a Participant may purchase during any Offering Period or Purchase Period.

Such modifications or amendments will not require stockholder approval or the consent of any Participants.

20.    Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

21.    Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

22.    Section 409A. The Plan is intended to be exempt from the application of Section 409A, and, to the extent not exempt, is intended to comply with Section 409A and any ambiguities herein will be interpreted to so be exempt from, or comply with, Section 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Section 409A. Notwithstanding the foregoing, the Company shall have no liability to a Participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under the Plan is compliant with Section 409A.

23.    Term of Plan. The Plan will become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It will continue in effect for a term of 20 years, unless sooner terminated under Section 19.

24.    Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within 12 months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

26.    No Right to Employment.

Furthermore, the Company or a Subsidiary or Affiliate may dismiss a Participant from employment at any time, free from any liability or any claim under the Plan.

27.    Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

28.    Compliance with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed accordingly.
