The Board is presently composed of five members: Michael F. Angelo, Gary W. Feiner, Kendall Larsen, Thomas M. O’Brien and Robert D. Short III, Ph.D. Mr. Larsen serves as Chairman of the Board of Directors.

Our Amended and Restated Certificate of Incorporation provides that the directors on our Board shall be divided into three classes, with the classes serving for staggered, three-year terms.

The term of each class of directors expires as follows: Class I at the 2023 annual meeting of stockholders, Class II at the Annual Meeting, and Class III at the 2022 annual meeting of stockholders. Each director shall hold office until his successor is elected and qualified or until his earlier death, resignation or removal.

Mr. Larsen does not hold director positions with any other reporting or registered investment companies. From April 2003 to July 2005, Mr. Larsen focused on pre-incorporation activities related to VirnetX Inc.

He has been the Chief Security Architect at NetIQ Corporation/Micro Focus Security Products Division, a global, enterprise software company since August 2005. From October 2003 to August 2005, Mr. Angelo was a Security Architect and Manager, Government Engagements SBU with Microsoft Corporation. From July 1989 to October 2003, Mr. Angelo was a Staff Fellow at both Hewlett Packard Company and Compaq Computer Corp.

As a holder of many patents in the fields of security and authentication, and as a result of his long and distinguished industry and scholarly background in the area of computer security and networking, Mr. Angelo brings to the Board critical technical and industry knowledge and expertise. With his extensive industry knowledge and having successfully served in multiple leadership capacities in various types of organizations, Mr. Angelo is uniquely qualified to serve as chair of the Company’s nominating and corporate governance committee.

Our directors are appointed to oversee the actions and results of our management. They were selected for their educational background, professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom and ability to represent the best interests of our stockholders. Their responsibilities include but are not limited to:

The Board believes that the Company’s Chief Executive Officer is best situated to serve as Chairman of the Board because he is the director most familiar with the Company’s business and industry, and most capable of effectively identifying strategic priorities and leading the execution of strategy. Independent directors and management have different perspectives and roles in strategy development. The Company’s independent directors bring experience, oversight and expertise from outside the Company and industry, while the Chief Executive Officer brings company-specific experience and expertise. The Board believes that the combined role of Chairman of the Board and Chief Executive Officer promotes strategy development and execution, and facilitates information flow between management and the Board, which is essential to effective governance.

The Company does not currently have a lead independent director. To ensure effective independent oversight, the Board has designed its leadership structure so that independent directors exercise oversight of the Company’s management and key issues related to strategy and risk. Only independent directors serve on and chair the audit committee, the compensation committee and the nominating and corporate governance committee of the Board. As a result of the Board’s committee system and majority of independent directors, the Board maintains effective oversight of our business operations, including independent oversight of our financial statements, executive compensation, selection of director candidates, and corporate governance programs. Accordingly, we believe that our current leadership structure is appropriate and enhances the Board’s ability to effectively carry out its roles and responsibilities on behalf of our stockholders.

Management is responsible for the day-to-day management of risks that the Company faces, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning, as designed. The Board believes that establishing the right “tone at the top” and full and open communication between management and the Board are essential for effective risk management and oversight. Senior management attends Board meetings quarterly and is available to address any questions or concerns raised by the Board on risk management and any other matters. Each quarter, the Board receives presentations from senior management on strategic matters involving our operations. The Board holds strategic planning sessions with senior management to discuss strategies, key challenges, risks and opportunities for the Company.

While the Board is ultimately responsible for risk oversight for the Company, our three Board committees assist the Board in fulfilling its oversight responsibilities with respect to certain areas of risk. The audit committee assists the Board in fulfilling its oversight responsibilities with respect to risk management in the areas of financial reporting, internal controls and compliance with legal and regulatory requirements. Our compensation committee assists the

Board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. The nominating and corporate governance committee assists the Board in fulfilling its oversight responsibilities with respect to the management of risks associated with Board organization, membership and structure, succession planning for our directors and executive officers, and corporate governance.

The Company notes that:

The Company’s compensation policies and practices are intended not to foster risk taking above the level of risk associated with the Company’s business model. Accordingly, the Company believes it has a balanced pay and performance program that does not promote excessive risk taking.

We have adopted a Code of Ethics for all employees and directors in accordance with the requirements of Item 406 of Regulation S-K and the NYSE Listed Company Manual. A copy of our Code of Ethics is available on our website at www.virnetx.com in the “Highlights” link in the “Corporate Governance” subcategory under the “Investors” tab, or by writing to us at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, Nevada 89448 (Attention: Investor Relations).

We intend to post on our website any amendment to, or waiver from, a provision of our Code of Ethics within four business days of such amendment or waiver.

The Board has a majority of independent directors and has determined that it is beneficial for us and our stockholders for our Chief Executive Officer and Chief Scientist to also be Board members. Other officers may, from time to time, serve as Board members, but no officer other than the Chief Executive Officer should be expected to be elected to the Board by virtue of his or her office.

The Board annually determines the independence of directors based on a review by the directors and the nominating and corporate governance committee. No director is considered independent unless the Board has determined that he or she has no material relationship with the Company, either directly or as a partner, stockholder, or officer of an organization that has a material relationship with the Company.

Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Exchange Act, and the listing standards of NYSE. Compensation committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and the listing standards of NYSE.

We have adopted rules for director independence standards of NYSE corporate governance listing standards and the rules and regulations of the SEC. The Board has determined that Michael F. Angelo, Gary W. Feiner and Thomas M. O’Brien meet the aforementioned independence standards.

The Board held a total of nine meetings during the fiscal year ended December 31, 2020, and no director attended fewer than 75% of the total number of meetings of the Board and the committees of which he was a member.

Since November 6, 2007, the Board has had a standing audit committee, compensation committee and nominating and corporate governance committee. Our audit committee charter, compensation committee charter, and nominating and corporate governance committee charter, each as adopted by the Board, and as may be amended from time to time, are posted on our website at www.virnetx.com in the “Highlights” link in the “Corporate Governance” subcategory under the “Investors” tab.

We encourage, but do not require, the Board members to attend our annual meetings of stockholders. All of our current Board members were in attendance for our 2020 Annual Meeting of Stockholders.

The Board has the following standing committees: audit committee, compensation committee and nominating and corporate governance committee. The following table details the membership of each standing committee and the number of meetings of each standing committee conducted during fiscal 2020:

Messrs. Angelo, Feiner and O’Brien comprise our nominating and corporate governance committee, or nominating and governance committee, with Mr. Angelo serving as the chairman. The Board has determined that each of Messrs. Angelo, Feiner and O’Brien meets NYSE requirements for independence. Our nominating and corporate governance committee met seven times during fiscal 2020.

Our nominating and corporate governance committee is responsible for, among other things:

A more detailed description of our nominating and corporate governance committee’s functions can be found in our nominating and corporate governance committee charter at www.virnetx.com in the “Highlights” link in the “Corporate Governance” subcategory under the “Investors” tab, or by writing to us at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, NV 89448 (Attention: Investor Relations).

The policy of our nominating and corporate governance committee is to consider properly submitted recommendations for candidates to the Board from stockholders. In evaluating such recommendations, our nominating and corporate governance committee seeks to achieve a balance of experience, knowledge, integrity, and

capability on the Board and to address the membership criteria set forth under “Director Qualifications” below. Any stockholder recommendations for consideration by our nominating and corporate governance committee should include (1) the name, age, business address and residence address of such person, (2) the principal occupation or employment of such person, (3) the class and number of shares of the Company that are beneficially owned by such person, and (4) any other information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act (including, without limitation, such person’s written consent to being named in the Proxy Statement as a nominee and to serving as a director if elected).

Stockholder recommendations to the Board should be sent to our Corporate Secretary at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, Nevada 89448.

In addition, our Bylaws permit stockholders to nominate directors for consideration at an annual meeting of stockholders. For a description of the process for nominating directors in accordance with our Bylaws, see “How do I submit a stockholder proposal for the 2022 Annual Meeting of Stockholders?” of this Proxy Statement and our Bylaws which have been filed with the SEC.

Our nominating and corporate governance committee evaluates and recommends candidates for membership on the Board consistent with criteria established by the Board. The Board has not formally established any specific, minimum qualifications that must be met by each candidate for the Board or specific qualities or skills that are necessary for one or more of the members of the Board. However, our nominating and corporate governance committee, when considering a potential candidate, will factor into its determination the following qualities of a candidate, among others: educational background, professional experience, including whether the person is a current or former chief executive officer or chief financial officer of a public company or the head of a division of a large international organization, knowledge of our business, integrity, professional reputation, independence, wisdom, and ability to represent the best interests of our stockholders, diversity, and with respect to diversity, such factors as gender, race, ethnicity and experience, area of expertise, potential conflicts of interest and other commitments and other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board.

Our nominating and corporate governance committee uses a variety of methods for identifying and evaluating nominees for any position on the Board. Our nominating and corporate governance committee regularly assesses the appropriate size and composition of the Board, the needs of the Board, the respective committees of the Board, and the qualifications of candidates in light of these needs. Candidates may come to the attention of the nominating and corporate governance committee through stockholders, management, current members of the Board, or third-party search firms engaged by the nominating and corporate governance committee.

Once the nominating and corporate governance committee has identified a prospective nominee, the nominating and corporate governance committee makes an initial determination as to whether to conduct a full evaluation of the candidate. This initial determination is based on the information provided to the nominating and corporate governance committee concerning the prospective candidate, as well as the nominating and corporate governance committee’s own knowledge of the prospective candidate, which may be supplemented by inquiries to the person making the recommendation or others. If the nominating and corporate governance committee determines, in consultation with other Board members as appropriate, that additional consideration is warranted, it may gather or request the third-party search firm to gather additional information about the prospective nominee’s background and experience. The nominating and corporate governance committee then evaluates the prospective nominee, taking into account whether the prospective nominee is independent within the meaning of the listing standards of NYSE and such other factors as it deems relevant, including the current composition of the Board, the balance of management and independent directors, the need for audit committee or compensation committee expertise, the prospective nominee’s qualifications as discussed above, the diversity of the member’s skills and experience in areas that are relevant to the Company’s businesses and activities, and its evaluations of other prospective nominees. In connection with this evaluation, the nominating and corporate governance committee determines whether to interview the prospective nominee and, if warranted, one or more members of the nominating and corporate governance committee and others, as appropriate, conduct interviews in person or by telephone. After completing this process, the

nominating and corporate governance committee makes a recommendation to the full Board as to the persons who should be nominated by the Board, and the Board determines the nominees after considering the recommendation and report of the nominating and corporate governance committee. The nominating and corporate governance committee follows the same process and uses the same criteria for evaluating candidates proposed by stockholders, members of the Board, and members of management.

The nominating and corporate governance committee considers diversity as one of a number of factors in identifying nominees for director. It does not, however, have a formal policy in this regard. The nominating and corporate governance committee views diversity broadly to include diversity of experience, skills, and viewpoint as well as traditional diversity concepts such as race or gender.

Messrs. Angelo, Feiner and O’Brien comprise our audit committee, with Mr. O’Brien serving as the chairman. The Board has determined that each of Messrs. Angelo, Feiner and O’Brien satisfies the requirements for independence under the rules and regulations of NYSE and the SEC, including the enhanced standards for audit committee members. The Board has also determined that Mr. O’Brien qualifies as an “audit committee financial expert” as defined in the SEC rules and satisfies the financial sophistication requirements of NYSE. Our audit committee met seven times during fiscal 2020.

Our audit committee is responsible for, among other things:

A more detailed description of our audit committee’s functions can be found in our audit committee charter at www.virnetx.com in the “Highlights” link in the “Corporate Governance” subcategory under the “Investors” tab, or by writing to us at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, Nevada 89448 (Attention: Investor Relations).

The following table sets forth the costs we incurred for services provided by Farber Hass Hurley LLP, our independent registered public accounting firm, which audited our financials for the years ended December 31, 2020 and December 31, 2019.

Audit Fees. Consists of fees billed for professional services rendered in connection with the audit of our consolidated financial statements, including the audit of internal control over financial reporting, review of the interim consolidated financial statements included in our quarterly reports, and accounting services in connection with securities offerings.

Audit-Related Fees. Consists of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” These services include consultations in connection with financial accounting and reporting standards.

Tax Fees. Consists of fees billed for professional services for tax compliance, tax advice and tax planning. We have nothing to report in this line item as we did not engage Farber Hass Hurley LLP to perform tax-related services for the Company.

All Other Fees. We have nothing to report in this line item as we did not engage Farber Hass Hurley LLP to perform services not covered by the preceding three categories.

Our audit committee’s policy is to pre-approve all services provided by our independent registered public accounting firm. For fiscal 2020, our audit committee pre-approved 100% of all services provided by our independent registered public accounting firm. These services include audit services and audit-related services. Our independent registered public accounting firm is required to periodically report to our audit committee regarding the extent of services provided by our independent registered public accounting firm in accordance with this pre-approval policy. Our audit committee may also delegate pre-approval authority to one or more of its members. Such member(s) must report any such pre-approval to our audit committee at the next scheduled meeting.

Messrs. Angelo, Feiner and O’Brien comprise our compensation committee, with Mr. Feiner serving as the chairman. The Board has determined that each of Messrs. Angelo, Feiner and O’Brien satisfies the requirements for independence under the rules of NYSE including the enhanced standards for compensation committee members, and is a “non-employee director” within the meaning of Section 16 of the Exchange Act. Our compensation committee met eight times during fiscal 2020.

Our compensation committee’s responsibilities and primary processes for establishing and overseeing executive compensation include, among other things:

Our Chief Executive Officer generally attends compensation committee meetings and makes recommendations to our compensation committee regarding the amount and form of the compensation of the other executive officers and key employees. He is not present for any of the executive sessions or for any decisions regarding his own compensation.

Except with respect to determining the Chief Executive Officer’s compensation, the compensation committee may delegate its authority to a subcommittee thereof and, to the extent permitted by applicable law, the compensation committee may delegate to officers or appropriate supervisory personnel the authority to grant stock awards to non-executive, non-director employees.

A more detailed description of our compensation committee’s functions can be found in our compensation committee charter at www.virnetx.com in the “Highlights” link in the “Corporate Governance” subcategory under the “Investors” tab, or by writing to us at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, Nevada 89448 (Attention: Investor Relations).

During fiscal 2020, Messrs. Angelo, Feiner and O’Brien served as members of our compensation committee. No member of our compensation committee was an officer or employee of VirnetX during fiscal 2020. In addition, no member of our compensation committee or executive officer of the Company served as a member of the Board or compensation committee of any entity that has an executive officer serving as a member of the Board or compensation committee.

Any of our stockholders who wish to communicate with the Board, a committee of the Board, the non-management directors as a group, or any individual member of the Board, may send correspondence to our Corporate Secretary at VirnetX Holding Corporation, P.O. Box 439, Zephyr Cove, Nevada 89448.

Our Corporate Secretary will compile and submit on a periodic basis all stockholder correspondence to our entire Board, or, if and as designated in the communication, to a committee of the Board, our non-management directors as a group, or an individual Board member. The independent directors of the Board review and approve the stockholders’ communications process periodically to ensure effective communication with stockholders.

Directors who are also our employees are not compensated for serving on the Board. Information regarding compensation otherwise received by our directors, who are also named executive officers, is provided under the heading “Executive Compensation.”

Our compensation committee periodically reviews director compensation in consultation with its independent compensation consultant, Compensia, Inc., or Compensia. Any recommendations for changes are made to our full Board by our compensation committee. Our compensation committee last reviewed our director compensation program with Compensia in April 2018 and determined that the program remains competitive and did not recommend any changes to the full Board in 2018, 2019, or 2020.

Our amended and restated 2013 Equity Incentive Plan, or the 2013 Plan, which was last approved by our stockholders in 2017, contains maximum limits on the size of the equity awards that can be granted to each of our non-employee directors in any fiscal year. Those maximum limits do not reflect the intended size of any potential grants or a commitment to make any equity award grants to our non-employee directors in the future. These maximum limits provide that no non-employee director may be granted, in any fiscal year, equity awards covering more than 100,000 shares, in the aggregate. Equity awards granted to an individual while he or she was an employee or a consultant, but not a non-employee director, do not count for purposes of these limits.

Consistent with our compensation policy, we provide the following cash compensation for non-employee directors:

We do not pay cash-based meeting fees for Board or committee meetings.

Consistent with our compensation policy, we provide the following stock compensation for non-employee directors:

The following table shows the compensation earned by or paid to each of our non-employee directors for fiscal 2020:

The following table lists all outstanding equity awards held by our non-employee directors as of December 31, 2020:

In May 2020, the Board declared a special cash dividend to shareholders of record as of the close of business on May 18, 2020 of $1.00 per share of common stock, payable on May 26, 2020 (the “2020 Dividend”).

In connection with the 2020 Dividend, the Board further approved equitable adjustments to all outstanding stock options and RSUs (the “Awards”) granted under the 2007 Plan and the 2013 Plan (together, the “Plans”) in its capacity as plan administrator under each Plan. Such adjustments resulted in a cash payment of $1.00 per share to each holder of outstanding Awards as of May 18, 2020 (the “Adjustment Payments”). Such Adjustment Payments resulted in payments to (1) each of Mr. Angelo, Mr. Feiner, and Mr. O’Brien of approximately $133,333, $100,833, and $123,333 respectively, and (2) each of Mr. Larsen, Dr. Short, and Mr. Nance of approximately $691,666, $1,368,334, and $107,996, respectively.

The timing and amounts of future dividends, if any, will depend on market conditions, corporate business and financial considerations and regulatory requirements.

The Board consists of five members. In accordance with our Amended and Restated Certificate of Incorporation, the Board is divided into three classes with staggered three-year terms. At the Annual Meeting, two Class II directors will be elected for three-year terms to serve until the 2024 annual meeting and until their respective successor is qualified and elected, or until their earlier death, resignation or removal.

The nominating and corporate governance committee of the Board recommended, and the Board approved, Thomas M. O’Brien and Robert D. Short III, Ph.D. as the Class II director nominees for election to the Board at the Annual Meeting. If elected, Messrs. O’Brien and Short will serve as directors until our annual meeting in 2024, and until their respective successors are qualified and elected or until their earlier death, resignation or removal. Messrs. O’Brien and Short are both current directors of the Company. Please see “Director Nominees” of this Proxy Statement for information concerning Messrs. O’Brien and Short.

Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR Messrs. O’Brien and Short as Class II directors. If the nominees are unable or decline to serve as a director at the time of the Annual Meeting, the proxies will be voted for another nominee(s) designated by the Board. We are not aware of any reason that the nominees would be unable or unwilling to serve as a director.

The two director nominees receiving the highest number of votes cast by the shares present (including virtually) or by proxy and entitled to vote at the Annual Meeting on this matter will be elected to the Board. Votes that are withheld will be excluded entirely and will have no effect in the election of directors.

The Board of Directors unanimously recommends that stockholders vote “FOR” the election of Thomas M. O’Brien and Robert D. Short III, Ph.D. as Class II Directors.

The audit committee has selected Farber Hass Hurley LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 and recommends that stockholders vote for ratification of such selection. Although ratification by stockholders is not required by law, the Company has determined that it is desirable to request ratification by the stockholders of this selection. If the stockholders do not ratify the selection of Farber Hass Hurley LLP, the audit committee may reconsider its selection. Notwithstanding its selection or voting results, the audit committee, in its discretion, may appoint a new independent registered public accounting firm at any time during the year if the audit committee believes that such a change would be in the best interests of the Company and its stockholders.

Farber Hass Hurley LLP has audited our consolidated financial statements annually since it was first appointed in fiscal year 2007. We expect that representatives of Farber Hass Hurley LLP will be present at the Annual Meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from stockholders.

Ratification of Farber Hass Hurley LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 will require the affirmative vote of a majority of the shares present (including virtually) or by proxy and entitled to vote at the Annual Meeting on this matter. Abstentions will have the same effect as a vote “against” the ratification of Farber Hass Hurley LLP as our independent registered public accounting firm.

The Board of Directors, on behalf of the audit committee, recommends that stockholders vote “FOR” the ratification of the selection of Farber Hass Hurley LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2021.

Our stockholders are being asked to approve an amendment and restatement of the 2013 Plan. In particular, we are seeking stockholder to approve an increase in the shares reserved under the 2013 Plan by 2,500,000 shares (the “Additional Shares”) from 5,000,000 shares to 7,500,000 shares (as amended, the “Amended 2013 Plan”).

If our stockholders approve this proposal, the addition of the Additional Shares to the Amended 2013 Plan will not result in the immediate grant of those Additional Shares to employees and other service providers. Instead, approval of this proposal will allow us the flexibility to issue competitive equity awards over approximately the next three years so that we can continue to incentivize and retain the key contributors to our business, as described in greater detail in this proposal.

Our Board has approved the Amended 2013 Plan, subject to the approval of our stockholders at the 2021 Annual Meeting of Stockholders and recommends that our stockholders to approve the Amended 2013 Plan.

If our stockholders approve the Amended 2013 Plan, it will replace the 2013 Plan and it will become effective as of the date of stockholder approval.

If our stockholders do not approve this proposal, the 2013 Plan will not be replaced with the Amended 2013 Plan. In that case, the existing shares reserved for issuance under the 2013 Plan may be insufficient to achieve our personnel incentive, recruiting and retention objectives following this year, making it more difficult to meet these objectives. This ultimately may undermine our success as a company.

Our executive officers and directors have an interest in the approval of the Amended 2013 Plan because they are eligible for awards under the 2013 Plan, as proposed to be amended by the Amended 2013 Plan.

A copy of the Amended 2013 Plan is included as Appendix A to this Proxy Statement. No amendments other than the proposed Authorized Shares amendment have been made to the 2013 Plan.

As of March 1, 2021, a total of 545,210 shares were available for issuance under the 2013 Plan. Under our current forecasts and taking into account our historical forfeiture rates, we expect that the number of shares still available for grant under the 2013 Plan will not provide a sufficient number of shares to meet the needs of our equity compensation program this year. As a result, we may not be able to issue equity to our employees, directors and consultants in amounts that we believe are necessary to attract, retain and motivate them unless our stockholders approve the Amended 2013 Plan.

This proposal seeks an authorization of an increase of 2,500,000 shares. The number of shares under the Amended 2013 Plan for which we are seeking authorization represents approximately 3.5% of our outstanding shares as of March 1, 2021. The proposed increase of 2,500,000 shares is to the number of shares available for issuance and such shares may be subject to awards as the Board or our compensation committee determines over the next several years. If our stockholders approve this proposal, the addition of these shares to the Amended 2013 Plan will not result in the immediate grant of these shares to employees and other service providers.

In setting the Additional Shares, our compensation committee and our Board considered the following:

As described in “Executive Compensation and Other Matters,” we implement and maintain compensation plans that tie a substantial portion of each employee’s overall compensation to key strategic financial and operational goals such as revenue generating activities, product and technical development, corporate public relations and stockholder value creation. Long-term equity awards are critical vehicle for helping us achieve this objective.

Our Board believes that the Company must offer a competitive equity incentive program if it is to continue to successfully attract and retain the best possible candidates for positions within the Company. Our Board expects that the Additional Shares under our Amended 2013 Plan will be vital in continuing to attract, retain and reward high caliber employees who are essential to our success and to provide incentives to these individuals to promote the success of the Company thereby aligning their interests with the interests of the Company’s stockholders.

The alternative to using equity for retention and incentive purposes would be to significantly increase cash compensation. We do not believe increasing cash compensation to make up for any shortfall in equity awards would be practical or advisable because, as a high-technology company, we believe that equity awards provide a more effective compensation vehicle than cash for attracting, retaining and motivating our employees and that equity awards align employees and stockholder long-term interests with a reduced impact on cash flow.

A description of the 2013 Plan, as amended by the Amended 2013 Plan, is included below. The 2013 Plan as proposed to be amended by this Proposal is otherwise unchanged from the 2013 Plan as previously approved by our Board and stockholders, except for the increase in the total authorized shares thereunder.

The full text of the 2013 Plan was annexed as Appendix A to our 2017 Proxy Statement, filed on April 14, 2017 with the SEC, which is available at the SEC’s website located at www.sec.gov. The Amended 2013 Plan is annexed as Appendix A to this Proxy Statement, a copy of which is also available at the SEC’s website. If approved by our stockholders, the Amended 2013 Plan will be effective on the date of the Annual Meeting, June 3, 2021.

The purposes of the Amended 2013 Plan are to attract and retain the best available personnel, to provide incentives to individuals who perform services to the Company, to align the interests of such individuals with the interests of the Company’s stockholders and to promote the success of the Company’s business. These incentives are provided through the grant of an option to purchase common stock of the Company, or stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, and performance shares, as the Administrator (as defined in the Amended 2013 Plan) may determine.

Subject to the adjustment provisions contained in the Amended 2013 Plan, stockholders are being asked to approve 2,500,000 shares of Company Common Stock for issuance under the Amended 2013 Plan so that the maximum shares of Company Common Stock reserved for issuance is 7,500,000, plus any shares subject to awards granted under the 2007 Stock Plan (the “2007 Plan”) that expire or otherwise terminate without having been exercised in full and shares issued pursuant to awards granted under the 2007 Plan that are forfeited to or repurchased

by the Company, with the shares subject to such awards credited to the share reserve as one share for every one share subject to such award and with the maximum number of shares to be added from the 2007 Plan equal to 3,736,946 shares. The shares may be authorized, but unissued, or reacquired Common Stock.

If any award granted under the Amended 2013 Plan expires or becomes unexercisable without having been exercised in full, or is forfeited to or repurchased by the Company, the expired, unexercised, forfeited or repurchased shares subject to such award will become available for future grant or sale under the Amended 2013 Plan. With respect to the exercise of stock appreciation rights, the net number of shares covered by the portion of the exercised award will cease to be available under the Amended 2013 Plan. If unvested shares of restricted stock, restricted stock units, performance shares or performance units are repurchased by or forfeited to the Company, such shares will become available for future grant under the Amended 2013 Plan. Shares used to pay the tax and/or exercise price of an award will become available for future grant or sale under the Amended 2013 Plan. Payment of cash rather than shares pursuant to an award will not result in reducing the number of shares available for issuance under the Amended 2013 Plan.

In the event of any dividend or other distribution (whether in the form of cash, shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of shares or other securities of the Company, or other change in the corporate structure affecting the Company’s common stock occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Amended 2013 Plan, will adjust the number and class of shares that may be delivered under the Amended 2013 Plan, and/or the number, class and price of shares of stock subject to outstanding awards, and the award grant limitations discussed below.

The Amended 2013 Plan contains annual grant limits intended to satisfy Section 162(m). Specifically, the maximum number of shares and/or dollars which could be issued to any one individual in any fiscal year of the Company pursuant to the Amended 2013 Plan is set forth below:

Separately, apart from Section 162(m), the Amended 2013 Plan provides that a non-employee Board member may not receive awards under the Plan covering more than 100,000 number of shares in any calendar year.

The Administrator will adjust the share limitations in this section in the event of any adjustment to the Company’s shares discussed above in the “Adjustment to Shares Subject to the Amended 2013 Plan” section.

Additionally, subject to the terms of the Amended 2013 Plan, the terms of outstanding awards may not be amended to reduce the exercise price of outstanding stock options or stock appreciation rights or cancel outstanding stock options or stock appreciation rights in exchange for cash, other awards or stock options or stock appreciation rights with an exercise price that is less than the exercise price of the original options or stock appreciation rights without stockholder approval.

The Board has delegated administration of the Amended 2013 Plan to the Board’s compensation committee. The Board and the compensation committee may further delegate administration of the Amended 2013 Plan to any committee of the Board, or a committee of individuals satisfying applicable laws appointed by the Board in accordance with the terms of the Amended 2013 Plan. For purposes of this description of the Amended 2013 Plan, the term “Administrator” will refer to the Board or any committee designated by the Board to administer the

Amended 2013 Plan. To make grants to certain officers and key employees of the Company, the members of the committee must qualify as “non-employee directors” under Rule 16b-3 of the Securities Exchange Act of 1934. In the case of awards intended to qualify for the performance-based compensation exemption under Section 162(m), administration must be by a committee comprised solely of two or more “outside directors” within the meaning of Section 162(m).

Subject to the terms of the Amended 2013 Plan, the Administrator has the sole discretion to select the service providers who will receive awards, to determine the terms and conditions of awards, to modify or amend each award (subject to the repricing restrictions of the Amended 2013 Plan), including to accelerate vesting or waive forfeiture restrictions, and to interpret the provisions of the Amended 2013 Plan and outstanding awards. The Administrator may allow a participant to defer the receipt of payment of cash or delivery of shares that otherwise would be due to such participant. The Administrator may make rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws and may make all other determinations deemed necessary or advisable for administering the Amended 2013 Plan.

Notwithstanding the foregoing, the Administrator cannot institute, without prior stockholder approval, an exchange program whereby the exercise prices of outstanding awards may be reduced, outstanding awards may be surrendered or cancelled in exchange for awards with a higher or lower exercise price, or outstanding awards may be transferred to a third party.

Awards may be granted to service providers of the Company and employees and consultants of any parent or subsidiary corporation of the Company. Incentive stock options may be granted only to employees who, as of the time of grant, are employees of the Company or any parent or subsidiary corporation of the Company. As of March 1, 2021, we had approximately 25 service providers (including 22 employees who are not directors, 2 employee directors, 3 non-employee directors and 1 consultant. While consultants are eligible to participate pursuant to the terms of the Amended 2013 Plan, the Company has not generally made equity grants to its consultants.

Each option granted under the Amended 2013 Plan will be evidenced by a written or electronic agreement between the Company and a participant specifying the number of shares subject to the option and the other terms and conditions of the option, consistent with the requirements of the Amended 2013 Plan.

The exercise price per share of each option may not be less than the fair market value of a share of the Company’s Common Stock on the date of grant. However, any incentive stock option granted to a person who at the time of grant owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company (a “Ten Percent Stockholder”) must have an exercise price per share equal to at least 110% of the fair market value of a share on the date of grant. The aggregate fair market value of the shares (determined on the grant date) covered by incentive stock options which first become exercisable by any participant during any calendar year also may not exceed $100,000. Generally, the fair market value of the Common Stock is the closing sales price of our stock as reported on the NYSE or such other national securities exchange or automated inter-dealer quotation system on which the shares are listed.

The Amended 2013 Plan provides that the Administrator will determine the acceptable form(s) of consideration for exercising an option. An option will be deemed exercised when the Company receives the notice of exercise and full payment for the shares to be exercised, together with applicable tax withholdings.

Options will be exercisable at such times or under such conditions as determined by the Administrator and set forth in the award agreement. The maximum term of an option will be specified in the award agreement, provided that options will have a maximum term of no more than ten (10) years, and provided further that an incentive stock option granted to a Ten Percent Stockholder must have a term not exceeding five (5) years.

The Administrator will determine and specify in each award agreement, and solely in its discretion, the period of post-termination exercise applicable to each option following the participant’s cessation of service with the Company. In the absence of such a determination by the Administrator, the participant generally will be able to exercise his or her option for (i) three (3) months following his or her cessation of service for reasons other than death or cause and (ii) three (3) years following his or her death (with all shares subject to the option becoming fully vested and exercisable); provided, however, that the option immediately will terminate upon a cessation of service for cause.

In addition, if the participant is terminated for cause, the Company has the option to repurchase at cost any shares previously acquired through the exercise of an option under the Amended 2013 Plan.

A stock appreciation right gives a participant the right to receive the appreciation in the fair market value of Company Common Stock between the date of grant of the award and the date of its exercise. Each stock appreciation right granted under the Amended 2013 Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the exercise price and the other terms and conditions of the award, consistent with the requirements of the Amended 2013 Plan.

The exercise price per share of each stock appreciation right may not be less than the fair market value of a share on the date of grant. Upon exercise of a stock appreciation right, the holder of the award will be entitled to receive an amount determined by multiplying (i) the difference between the fair market value of a share on the date of exercise over the exercise price by (ii) the number of exercised shares. The Company may pay the appreciation in cash, in shares, or in some combination thereof. The term of a stock appreciation right will be no more than ten (10) years from the date of grant. The terms and conditions relating to the period of post-termination exercise and the Company repurchase rights with respect to options described above also apply to stock appreciation rights.

Awards of restricted stock are rights to acquire or purchase shares, which vest in accordance with the terms and conditions established by the Administrator in its sole discretion. Each restricted stock award granted will be evidenced by a written or electronic agreement between the Company and the participant specifying the number of shares subject to the award and the other terms and conditions of the award, consistent with the requirements of the Amended 2013 Plan. Restricted stock awards may be subject to vesting conditions as the Administrator specified, and the shares acquired may not be transferred by the participant until vested. Notwithstanding the foregoing, if the Administrator desires that the award qualify as performance-based compensation under Section 162(m), any restrictions will be based on a specified list of performance goals and certain other requirements (see “Performance Goals” below for more information).

Unless otherwise provided by the Administrator, a participant will forfeit any shares of restricted stock as to which the restrictions have not lapsed prior to the participant’s termination of service. In addition, if the participant is terminated for cause, the Company has the option to repurchase at cost any vested shares previously acquired through an award of restricted stock under the Amended 2013 Plan.

Unless the Administrator provides otherwise, participants holding restricted stock will have the right to vote the shares and to receive any dividends paid, except that dividends or other distributions paid in shares will be subject to the same restrictions on transferability and forfeitability as the original award. The Administrator may, in its sole discretion, reduce or waive any restrictions and may accelerate the time at which any restrictions will lapse or be removed.

The Administrator may grant restricted stock units which represent a right to receive shares at a future date as set forth in the participant’s award agreement. Each restricted stock unit granted under the Amended 2013 Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the number of shares subject to the award and other terms and conditions of the award, consistent with the requirements of the Amended 2013 Plan.

Restricted stock units will result in a payment to a participant only if the performance goals or other vesting criteria the Administrator may establish are achieved or the awards otherwise vest. Notwithstanding the foregoing, if the Administrator desires that the award qualify as performance-based compensation under Section 162(m), any restrictions will be based on a specified list of performance goals and certain other requirements (see “Performance Goals” below for more information).

After the grant of a restricted stock unit award, the Administrator, in its sole discretion, may reduce or waive any restrictions or vesting criteria that must be met to receive a payout and may accelerate the time at which any restrictions will lapse or be removed. A participant will forfeit any unearned restricted stock units as of the date set forth in the award agreement. The Administrator in its sole discretion may pay earned restricted stock units in cash, shares of the Company’s Common Stock, or a combination of cash and shares.

Performance units and performance shares may also be granted under the Amended 2013 Plan. Each award of performance units or shares granted under the Amended 2013 Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the performance period and other terms and conditions of the award, consistent with the requirements of the Amended 2013 Plan. Performance units and performance shares will result in a payment to a participant only if the performance goals or other vesting criteria the Administrator may establish are achieved or the awards otherwise vest.

Earned performance units and performance shares will be paid, in the sole discretion of the Administrator, in the form of cash, shares (which will have an aggregate fair market value equal to the earned performance units or shares at the close of the applicable performance period), or in a combination thereof. The Administrator may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment or service), or any other basis determined by the Administrator, in its discretion. Notwithstanding the foregoing, if the Administrator desires that the award qualify as performance-based compensation under Section 162(m), any restrictions will be based on a specified list of performance goals and certain other requirements (see “Performance Goals” below for more information).

After the grant of a performance unit or performance share, the Administrator, in its sole discretion, may accelerate, reduce or waive any performance objectives or other vesting provisions for such performance units or shares. Performance units will have an initial value established by the Administrator on or before the date of grant. Each performance share will have an initial value equal to the fair market value of a share on the grant date. A participant will forfeit any performance shares or units that are unearned or unvested as of the date set forth in the award agreement.

The granting and/or vesting of awards of Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units, and other incentives under the Amended 2013 Plan may be made subject to the attainment of performance goals relating to one or more business criteria within the meaning of Section 162(m) and may provide for a targeted level or levels of achievement (“performance goals”) including: earnings before interest, taxes, depreciation and amortization (EBITDA), earnings before taxes and net earnings, earnings per Share, gross margin, new product development or innovation, net income, operating income, quality, operating margin, return on capital, return on equity, revenue, revenue growth, and total stockholder return. The performance goals may differ from participant to participant and from award to award. Any criteria used may be measured (as applicable), in absolute terms, in combination with another performance goal or goals (for example, as a ratio or matrix), in relative terms (including, but not limited to, results for other periods, passage of time and/or against another company or companies or an index or indices), on a per-share or per-capita basis, against the performance of the Company as a whole or a segment of the Company (including, but not limited to, any combination of the Company and any subsidiary, division, joint venture, affiliate, and/or other segment), and/or on a pre-tax or after-tax basis. Prior to latest date by which would meet the requirements under Section 162(m), the Administrator will determine whether any significant element(s) or item(s) will be included or excluded from the calculation of performance goals with respect to any award recipient. As determined in the discretion of the Administrator latest date by which would meet the requirements under Section 162(m), achievement of performance goals for a particular award may be calculated in accordance with generally accepted accounting principles (“GAAP”), or on a basis other than GAAP.

To the extent necessary to comply with the performance-based compensation provisions of Section 162(m), with respect to any award granted subject to performance goals, and no later than the latest possible date that could be used and still comply with the performance-based compensation provisions of Section 162(m), the Administrator will, in writing: (i) designate one or more participants, who would be considered a “covered employee” within the meaning of Code Section 162(m), to whom an award will be made, (ii) select the performance goals applicable to the performance period, (iii) establish the performance goals, and amounts or methods of computation of the awards which may be earned for the performance period, and (iv) specify the relationship between performance goals and the amounts or methods of computation of such awards, as applicable, to be earned by each participant for such performance period. Following the completion of each performance period, the Administrator will certify in writing whether the applicable performance goals have been achieved for such performance period. In determining the amounts earned by a participant, the Administrator may reduce or eliminate (but not increase) the amount payable

at a given level of performance to take into account additional factors that the Administrator may deem relevant to the assessment of individual or corporate performance for the performance period. A participant will be eligible to receive payment pursuant to an award for a performance period only if the performance goals for such period are achieved.

Unless determined otherwise by the Administrator, awards granted under the Amended 2013 Plan generally are not transferable other than by will or by the laws of descent or distribution, and all rights with respect to an award granted to a participant generally will be available during a participant’s lifetime only to the participant.

In the event of the Company’s proposed dissolution or liquidation, the Administrator will notify each participant as soon as practicable prior to the effective date of such proposed transaction. An award will terminate immediately prior to consummation of such proposed action to the extent the award has not been previously exercised.

The Amended 2013 Plan provides that, in the event of a merger or a “change in control” (as defined in the Amended 2013 Plan), each award will be treated as the Administrator determines, including that each award be assumed or substantially equivalent awards substituted by the acquiring or succeeding corporation or its affiliate. The Administrator will not be required to treat all outstanding awards the same in the transaction.

If the successor corporation does not assume or substitute for the award, the participant will fully vest in and have the right to exercise all of his or her outstanding options and stock appreciation rights, all restrictions on restricted stock will lapse, and, with respect to restricted stock units, performance shares, and performance units, all performance goals or other vesting criteria will be deemed achieved target levels and all other terms and conditions met. In addition, if an option or stock appreciation right is not assumed or substituted for, the Administrator will notify the participant in writing or electronically that the option or stock appreciation right will be fully vested and exercisable for a period of time determined by the Administrator in its sole discretion, and the option or stock appreciation right will terminate upon the expiration of such period.

If the successor corporation assumes or substitutes outstanding awards held by a non-employee director and the non-employee director ceases to be a director prior to or on the closing of the merger or change in control or within twelve months following the merger or change in control, then his or her options and stock appreciation rights will fully vest and become immediately exercisable. In addition, all restrictions on restricted stock, restricted stock units, performance shares, or performance units held by such non-employee director will lapse, and all performance goals or other vesting requirements will be deemed achieved at 100%, and all other terms and conditions met.

The Administrator may specify in an award agreement under the Amended 2013 Plan that a participant’s rights, payments, and benefits with respect to an award will be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an award. Such events may include, but are not limited to, fraud, breach of a fiduciary duty, restatement of financial statements as a result of fraud or willful errors or omissions, termination of employment for cause, violation of our material policies, breach of non-competition, confidentiality, or other restrictive covenants that may apply to the participant, or other conduct by the participant that is detrimental to our business or reputation.

The Amended 2013 Plan will automatically terminate ten (10) years from the date of its original adoption by the Board in 2013, unless terminated at an earlier time by the Board. The Administrator may amend, alter, suspend or terminate the Amended 2013 Plan at any time, provided that no amendment may be made without stockholder approval to the extent approval is necessary or desirable to comply with any applicable laws. No amendment, alteration, suspension or termination may impair the rights of any participant unless mutually agreed otherwise between the participant and the Administrator.

The following summary is intended only as a general guide to the material U.S. federal income tax consequences of participation in the Amended 2013 Plan as of March 2021. The summary is based on existing U.S. laws and regulations, and there can be no assurance that those laws and regulations will not change in the future. The summary does not purport to be complete and does not discuss the tax consequences upon a participant’s death, or the provisions of the income tax laws of any municipality, state or foreign country in which the participant may reside. As a result, tax consequences for any particular participant may vary based on individual circumstances.

An optionee recognizes no taxable income for regular income tax purposes as a result of the grant or exercise of an incentive stock option qualifying under Section 422 of the Code. Optionees who neither dispose of their shares within two (2) years following the date the option was granted nor within one (1) year following the exercise of the option normally will recognize a capital gain or loss equal to the difference, if any, between the sale price and the purchase price of the shares. If an optionee satisfies such holding periods upon a sale of the shares, the Company will not be entitled to any deduction for federal income tax purposes. If an optionee disposes of shares within two (2) years after the date of grant or within one (1) year after the date of exercise (a “disqualifying disposition”), the difference between the fair market value of the shares on the exercise date and the option exercise price (not to exceed the gain realized on the sale if the disposition is a transaction with respect to which a loss, if sustained, would be recognized) will be taxed as ordinary income at the time of disposition. Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. Any ordinary income recognized by the optionee upon the disqualifying disposition of the shares generally should be deductible by the Company for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of the Code.

The difference between the option exercise price and the fair market value of the shares on the exercise date is treated as an adjustment in computing the optionee’s alternative minimum taxable income and may be subject to an alternative minimum tax which is paid if such tax exceeds the regular tax for the year. Special rules may apply with respect to certain subsequent sales of the shares in a disqualifying disposition, certain basis adjustments for purposes of computing the alternative minimum taxable income on a subsequent sale of the shares and certain tax credits which may arise with respect to optionees subject to the alternative minimum tax.

Options not designated or qualifying as incentive stock options will be nonstatutory stock options having no special U.S. tax status. An optionee generally recognizes no taxable income as the result of the grant of such an option. Upon exercise of a nonstatutory stock option, the optionee normally recognizes ordinary income equal to the amount that the fair market value of the shares on such date exceeds the exercise price. If the optionee is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of stock acquired by the exercise of a nonstatutory stock option, any gain or loss, based on the difference between the sale price and the fair market value on the exercise date, will be taxed as capital gain or loss. No tax deduction is available to the Company with respect to the grant of a nonstatutory stock option or the sale of the stock acquired pursuant to such grant.

In general, no taxable income is reportable when a stock appreciation right is granted to a participant. Upon exercise, the participant generally will recognize ordinary income in an amount equal to the fair market value of any shares of our Common Stock received. Any additional gain or loss recognized upon any later disposition of the shares would be capital gain or loss.

A participant acquiring restricted stock generally will recognize ordinary income equal to the fair market value of the shares on the vesting date. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. The participant may elect, pursuant to Section 83(b) of the Code, to accelerate the ordinary income tax event to the date of acquisition by filing an election with the Internal Revenue

Service no later than thirty (30) days after the date the shares are acquired. Upon the sale of shares acquired pursuant to a restricted stock award, any gain or loss, based on the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.

There are no immediate tax consequences of receiving an award of restricted stock units. A participant who is awarded restricted stock units generally will be required to recognize ordinary income in an amount equal to the fair market value of shares issued to such participant at the end of the applicable vesting period or, if later, the settlement date elected by the Administrator or a participant. Any additional gain or loss recognized upon any later disposition of any shares received would be capital gain or loss.

A participant generally will recognize no income upon the grant of a performance share or a performance unit award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any cash or nonrestricted shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.

Section 409A of the Code provides certain new requirements for nonstatutory deferred compensation arrangements with respect to an individual’s deferral and distribution elections and permissible distribution events. Awards granted under the Amended 2013 Plan with a deferral feature will be subject to the requirements of Section 409A of the Code. If an award is subject to and fails to satisfy the requirements of Section 409A of the Code, the recipient of that award may recognize ordinary income on the amounts deferred under the award, to the extent vested, which may be prior to when the compensation is actually or constructively received. Also, if an award that is subject to Section 409A fails to comply with Section 409A’s provisions, Section 409A imposes an additional 20% federal income tax on compensation recognized as ordinary income, as well as interest on such deferred compensation. Certain states have enacted laws similar to Section 409A which impose additional taxes, interest and penalties on nonstatutory deferred compensation arrangements. The Company will also have withholding and reporting requirements with respect to such amounts.

The Company generally will be entitled to a tax deduction in connection with an award under the Amended 2013 Plan in an amount equal to the ordinary income realized by a participant and at the time the participant recognizes such income (for example, the exercise of a nonstatutory stock option). Special rules limit the deductibility of compensation paid to our Chief Executive Officer and other “covered employees” as determined under Section 162(m) and applicable guidance. Under Section 162(m), the annual compensation paid to any of these specified executives will be deductible only to the extent that it does not exceed $1,000,000. However, we can preserve the deductibility of certain compensation in excess of $1,000,000 if the conditions of Section 162(m) are met. These conditions include (among others) stockholder approval of the Amended 2013 Plan, setting limits on the number of awards that any individual may receive and for awards other than certain stock options, establishing performance criteria that must be met before the award actually will vest or be paid. The Amended 2013 Plan has been designed to permit (but not require) the Administrator to grant awards are intended to qualify as performance-based for purposes of satisfying the conditions of Section 162(m).

THE FOREGOING IS ONLY A SUMMARY OF THE EFFECTS OF FEDERAL INCOME TAXATION UPON PARTICIPANTS AND THE COMPANY WITH RESPECT TO AWARDS UNDER THE AMENDED 2013 PLAN. IT DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF A PARTICIPANT’S DEATH OR THE PROVISIONS OF THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE PARTICIPANT MAY RESIDE.

The number of Awards that an employee, director or consultant may receive under the Amended 2013 Plan is in the discretion of the Administrator and therefore cannot be determined in advance. The following table sets forth for each of our named executive officers, executive officers as a group, non-employee directors, as a group, all employees (other than executive officers, as a group) and all non-employee service providers, as a group (i) the aggregate number of shares of common stock subject to options granted under the 2013 Plan during the last fiscal year, (ii) the average per share exercise price of such options, (iii) the aggregate number of RSUs granted under the 2013 Plan and (iv) the grant date value of these RSUs.

The approval of the amendment and restatement of the 2013 Plan will require the affirmative vote of a majority of the shares present in person or by proxy and entitled to vote at the Annual Meeting on this matter. Abstentions will have the same effect of a vote “against” the amendment and restatement of the 2013 Plan.

We strongly believe that the approval of the amendment and restatement of the 2013 Plan is essential to our continued success. Our employees are one of our most valuable assets. Stock options and other awards such as those provided under the 2013 Plan are vital to our ability to attract and retain outstanding and highly skilled individuals. Such awards also are crucial to our ability to motivate employees to achieve the Company’s goals. For the reasons stated above, the stockholders are being asked to approve the amendment and restatement of the 2013 Plan.

The Board of Directors unanimously recommends that you vote “FOR” the amendment and restatement of the 2013 Plan.

The biographies of Mr. Larsen and Dr. Short are set forth under the heading “Board of Directors” in this Proxy Statement.

Each officer serves at the discretion of the Board and holds office until his successor is duly elected and qualified or until his earlier resignation or removal. There are no family relationships among any of our directors or executive officers.

The compensation committee has reviewed our relationship with Compensia pursuant to NYSE and SEC rules and has found no conflict of interest in Compensia continuing to provide advice to the compensation committee. The compensation committee is also regularly advised by our primary outside corporate and compensation and benefits legal counsel, Wilson Sonsini Goodrich & Rosati, Professional Corporation (“WSGR”). The compensation committee has reviewed our relationship with WSGR pursuant to NYSE and SEC rules and has found no conflict of interest in WSGR continuing to provide advice to the compensation committee.

Our executive compensation program consists of the following elements:

Stock-based awards are made at the commencement of employment, may be made annually based upon performance and, occasionally, following a significant change in job responsibilities or to meet other special retention objectives. The compensation committee reviews and approves stock-based awards to named executive officers based upon a review of competitive compensation data, its assessment of individual performance, a review of each executive’s existing long-term incentives, and retention considerations. In determining the number of stock options and RSUs to be granted to our named executive officers, we take into account the individual’s position, scope of responsibility, ability to affect profits and stockholder value, the individual’s historic and recent performance, the value of stock options and RSUs and percent of company granted in relation to other elements of the individual executive’s total compensation and relative to comparable companies. We expect to continue to use stock options and RSUs as a long-term incentive vehicle, potentially in combination with equity award types, because we believe that stock options and RSUs:

In fiscal 2020, the compensation committee undertook a full review of the compensation of our named executive officers, and following this review, in June 2020, the compensation committee made the following decisions (as described in greater detail in the sections below):

The compensation for our named executive officers for fiscal 2020 is presented in the table below.

Mr. Larsen is our President and Chief Executive Officer, as well as Chairman of the Board. Mr. Larsen, a founder of VirnetX Inc., has driven the organization’s performance, leading it from inception, through the early start-up phase and through several rounds of financing. He has also helped drive significant growth in our revenues and market capitalization, as well as achievement of our operational and strategic milestones. The compensation committee believes that Mr. Larsen is critical to our ability to pursue our licensing strategy going forward. In light of these considerations and the other factors described above, in June 2020, the compensation committee increased Mr. Larsen’s base salary from $675,182 to $702,189, an increase of approximately $27,000, or 4%, over fiscal 2019. The compensation committee felt this salary increase was warranted due to the value Mr. Larsen brings to the Company through his key role in the management of the Company during his long tenure, as well as our successes under his leadership in product development, licensing, and litigation matters.

Dr. Short has significant scientific and technological expertise, and the compensation committee considered his technical, scientific and management skills, his level of responsibility and expected contributions to intellectual property and product development. In light of these considerations and the other factors described above, in June 2020, the compensation committee increased Dr. Short’s base salary from $429,585 to $446,768, an increase of approximately $17,000, or 4%, over fiscal 2019. The compensation committee felt this salary increase was appropriate given his long tenure with us and contributions to our business.

Mr. Nance has significant public company experience, and the compensation committee considered his technical and strategic skills, his level of responsibility and expected contributions to our further success. In accordance with his continued role as CFO on a part-time basis, the compensation committee approved a base salary of $180,709 for Mr. Nance, which the compensation committee believed was appropriate given his long tenure with us and contributions to our business.

In fiscal 2020, the compensation committee increased the fiscal 2020 target incentive opportunity percentages for Mr. Larsen, Dr. Short and Mr. Nance to 75% of fiscal 2020 base salary, compared to 50% of base salary in fiscal 2019. In December 2020, the compensation committee reviewed the Company’s performance in fiscal 2020 and the contributions that our named executive officers made to such performance. The compensation committee determined to pay each of Mr. Larsen, Dr. Short and Mr. Nance 75% of their respective fiscal 2020 base salary in light of the Company’s overall performance for fiscal 2020. In making such payments, the compensation committee considered various factors, including advances in product development and their contributions in achieving this performance, the achievement of certain licensing, technical, and litigation milestones, and the development of the Company’s patent portfolio, none of which were given any particular weight or assigned a dollar value. The resulting aggregate fiscal 2020 annual incentive bonus payments paid to Mr. Larsen, Dr. Short and Mr. Nance were $526,642, $335,076 and $135,532, respectively.

In fiscal 2019, the compensation committee maintained the fiscal 2018 target incentive opportunity percentages for Mr. Larsen, Dr. Short and Mr. Nance at 50% of fiscal 2019 base salary. Due to the state of the market and the position of the Company, the compensation committee did not pay any annual incentive bonuses to our named executive officers in fiscal 2019. In March 2020, the compensation committee determined to pay each of Mr. Larsen, Dr. Short and Mr. Nance a special bonus representing 75% of their respective fiscal 2019 base salary. In making such payments, the compensation committee considered various factors, including (1) the Company’s performance at the time, (2) payment of approximately $500 million from Apple, Inc. as a result of a judgment in the Company’s ongoing litigation against Apple and the contributions that our named executive officers made to this significant

achievement, and (3) that annual incentive bonuses were not paid in fiscal 2019. The resulting aggregate special bonus payments paid to Mr. Larsen, Dr. Short and Mr. Nance were $506,386, $322,189 and $130,319, respectively (each, a “March Special Bonus”).

In fiscal 2020, the compensation committee approved grants of stock options and RSUs to Mr. Larsen, Dr. Short and Mr. Nance as shown in the table below.

In determining fiscal 2020 stock option awards and stock awards for Mr. Larsen, Dr. Short and Mr. Nance, the compensation committee reviewed various factors, including the Company’s performance, each officer’s performance and perceived criticality to future success, market practices with respect to long-term incentives, and total annual equity allocations at the Company for fiscal 2020.

Our named executive officers participate in the same group insurance and employee benefit plans as our other salaried employees. At this time, we do not provide special benefits or other perquisites to our named executive officers.

We do not provide change in control agreements or employment agreements providing formal cash or equity severance rights to any of our named executive officers. Our 2013 Plan allows the Board to determine the terms and condition of awards issued thereunder. The Board has made the determination that all equity awards issued under our 2013 Plan will include the provision that in the event of a “Change in Control” (as defined in our 2013 Plan), all unvested shares underlying the option and all unvested RSUs will vest and become exercisable immediately prior to the consummation of such Change in Control transaction.

As stated elsewhere in this Proxy Statement, we do not provide change in control agreements or employment agreements providing formal cash or equity severance rights to any of our named executive officers. However, the Board has made the determination that all equity awards issued under our 2013 Plan will include the provision that in the event of a “Change in Control” (as defined in our 2013 Plan), all unvested shares underlying the option and all unvested RSUs will vest and become exercisable immediately prior to the consummation of such Change in Control transaction.

Section 16(a) of the Exchange Act requires that our executive officers and directors, and persons who own more than 10% of our common stock, file reports of ownership and changes of ownership with the SEC. Such directors, executive officers and 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

SEC regulations require us to identify in this proxy statement anyone who filed a required report late during the most recent fiscal year. Based on our review of forms filed with the SEC, or written representations from reporting persons stating that they were not required to file these forms, we believe that during our fiscal year ended December 31, 2020, all Section 16(a) filing requirements were satisfied on a timely basis, with the exception of the failure to timely file Forms 4 for Richard Nance and Robert D. Short III, Ph.D. reporting the withholding of shares to satisfy income tax and withholding and remittance obligations in connection with the net settlement of RSUs (both filed with the SEC June 23, 2020).

Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the Plan. Shares used to pay the exercise price of an Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under

the Plan. Notwithstanding the foregoing and, subject to adjustment as provided in Section 15, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 3(b).

(c) Share Reserve. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan.

(a) Procedure.

(i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan.

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be administered by a Committee of two (2) or more “outside directors” within the meaning of Section 162(m) of the Code.

(iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

(iv) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a Committee, which committee will be constituted to satisfy Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion:

(i) to determine the Fair Market Value;

(ii) to select the Service Providers to whom Awards may be granted hereunder;

(iii) to determine the number of Shares to be covered by each Award granted hereunder;

(iv) to approve forms of Award Agreements for use under the Plan;

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine;

(vi) to determine the terms and conditions of any, and with the approval of the Company’s stockholders, to institute an Exchange Program;

(vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan;

(viii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws or for qualifying for favorable tax treatment under applicable foreign laws;

(ix) to modify or amend each Award (subject to Section 20 of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(b) of the Plan regarding Incentive Stock Options); provided, however, that the Administrator may not, without the prior approval of the Company’s stockholders: (A) modify or amend an Option or Stock Appreciation Right to reduce the exercise price of such Option or Stock Appreciation Right after it has been granted (except for adjustments made pursuant to Section 15), or (B) cancel any outstanding Option or Stock Appreciation Right and immediately replace it with a new Option or Stock Appreciation Right with a lower exercise price;

(x) to allow Participants to satisfy tax withholding obligations in such manner as prescribed in Section 16 of the Plan;

(xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator;

(xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; and

(xiii) to make all other determinations deemed necessary or advisable for administering the Plan.

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards.

(a) Grant of Options. Subject to the terms and conditions of the Plan, Option may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. Subject to Section 12 and the other terms and conditions of the Plan, the Administrator will have complete discretion to determine the number of Shares granted to any Service Provider. Each Option shall be evidenced by an Award Agreement (which may be in electronic form) that shall specify the exercise price, the expiration date of the Option, the number of Shares covered by the Option, any conditions to exercise the Option, and such other terms and conditions as the Administrator, in its discretion, shall determine.

(b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement.

(c) Option Exercise Price and Consideration.

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by the Administrator, subject to the following:

(1) In the case of an Incentive Stock Option

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant.

(B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant.

(2) In the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant.

(3) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code.

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

(iii) Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the

Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise; (7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment.

(d) Exercise of Option.

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

An Option will be deemed exercised when the Company receives: (i) a notice of exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability or termination for Cause, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for thirty (30) days following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for six (6) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(iv) Death of Participant. If a Participant dies while a Service Provider, or dies within thirty (30) days following the day Participant ceases to be a Service Provider, the Option may be exercised following the Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of the term of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the

Administrator. If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

(v) Termination for Cause. In the event a Participant ceases to be a Service Provider as a result of the Participant’s termination for Cause, the Option shall immediately terminate in its entirety upon first notification to the Participant of Participant’s termination for Cause. If a Participant Service Provider status is suspended pending an investigation of whether the Participant shall be terminated for Cause, all of the Participant’s rights under the Option likewise shall be suspended during the investigation period and the Participant shall have no right to exercise the Option. This Section 6(d)(v) shall apply with equal effect to vested Shares acquired upon exercise of the Option granted on any date on which the Common Stock is not listed on any established stock exchange or national market system, in that the Company shall have the right to repurchase such Shares from the Participant upon the following terms: (A) the repurchase is made within ninety (90) days of the date Participant ceases to be a Service Provider, at the Fair Market Value of the Shares as of the date of such termination, (B) consideration for the repurchase consists of cash or cancellation of purchase money indebtedness, and (C) the repurchase right terminates upon the effective date of the Company’s initial public offering of its Common Stock on any established stock exchange or national market system. Notwithstanding the foregoing, with respect to vested Shares issued upon exercise of an Option granted to any Officer, Director or Consultant, the Company’s right to repurchase such Shares upon the date that Participant ceases to be a Service Provider as a result of termination for Cause shall be made at the Participant’s original cost for the Shares and shall be effected pursuant to such terms and conditions, and at such time, as the Administrator shall determine. Nothing in this Section 6(d)(v) shall in any way limit the Company’s right to purchase unvested Shares issued upon exercise of an Option as set forth in the applicable Award Agreement.

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed.

(c) Transferability. Except as provided in this Section 7 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate.

(e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed.

(f) Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise.

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid.

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan.

(i) Termination for Cause. In the event a Participant ceases to be a Service Provider as a result of the Participant’s termination for Cause, the Participant paid consideration to purchase Shares granted pursuant to a Restricted Stock Award, and the Administrator granted the Award to purchase Restricted Stock on any date on which the Common Stock is not listed on any established stock exchange or national market system, the Company shall have the right to repurchase from the Participant the Shares of Restricted Stock purchased by Participant for which restrictions have lapsed upon the following terms: (A) the repurchase is made within ninety (90) days of the date Participant ceases to be a Service Provider at the Fair Market Value of the Shares as of the date of such termination, (B) consideration for the repurchase consists of cash or cancellation of purchase money indebtedness, and (C) the repurchase right terminates upon the effective date of the Company’s initial public offering of its Common Stock on any established stock exchange or national market system. Notwithstanding the foregoing, with respect to Restricted Stock issued to any Officer, Director or Consultant, the Company’s right to repurchase Shares of Restricted Stock for which restrictions have lapsed upon the date that Participant ceases to be a Service Provider as a result of termination for Cause shall be made at the Participant’s original cost for the Shares and shall be effected pursuant to such terms and conditions, and at such time, as the Administrator shall determine. Nothing in this Section 7(i) shall in any way limit the Company’s right to purchase Shares of Restricted Stock for which restrictions have not lapsed as set forth in the Award Agreement evidencing the applicable Award of Restricted Stock.

(j) Section 162(m) Performance Restrictions. For purposes of qualifying grants of Restricted Stock as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock which is intended to qualify under Section 162(m) of the Code, the Administrator will follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals).

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units.

(b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws or any other basis determined by the Administrator in its discretion.

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout.

(d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of both.

(e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company.

(f) Section 162(m) Performance Restrictions. For purposes of qualifying grants of Restricted Stock Units as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock Units which are intended to qualify under Section 162(m) of the Code, the Administrator will follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals).

(a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion.

(b) Number of Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted to any Service Provider.

(c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued pursuant to exercise of a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan.

(d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(b) relating to the maximum term and Section 6(d) relating to exercise and repurchase also will apply to Stock Appreciation Rights.

(f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

(i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(ii) The number of Shares with respect to which the Stock Appreciation Right is exercised.

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some combination thereof.

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each Participant.

(b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant.

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period”, and will consist of any Fiscal Year of the Company or such other period as determined by the Administrator in its sole discretion. Each Award of Performance

Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share.

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof.

(f) Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan.

(g) Section 162(m) Performance Restrictions. For purposes of qualifying grants of Performance Units/Shares as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Performance Units/Shares which are intended to qualify under Section 162(m) of the Code, the Administrator will follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals).

(a) General. If the Administrator, in its discretion, decides to grant an Award intended to qualify as “performance-based compensation” under Code Section 162(m), the provisions of this Section 11 will control over any contrary provision in the Plan; provided, however, that the Administrator may in its discretion grant Awards that are not intended to qualify as “performance-based compensation” under Section 162(m) of the Code to such Participants that are based on Performance Goals or other specific criteria or goals but that do not satisfy the requirements of this Section 11.

(b) Performance Goals. The granting and/or vesting of Awards of Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units and other incentives under the Plan may be made subject to the attainment of performance goals relating to one or more business criteria within the meaning of Code Section 162(m). As determined by the Administrator, the Performance Goals applicable to an Award may provide for a targeted level or levels of achievement using one or more of the following measures: earnings (which may include earnings before interest, taxes, depreciation and amortization (“EBITDA”), earnings before taxes and net earnings), earnings per share, gross margin, new product development or innovation, net income, operating income, quality, operating margin, return on capital, return on equity, revenue, revenue growth, and total stockholder return. The Performance Goals may differ from Participant to Participant and from Award to Award. Any criteria used may be measured, as applicable, (i) in absolute terms, (ii) in combination with another Performance Goal or Goals (for example, but not by way of limitation, as a ratio or matrix), (iii) in relative terms (including, but not limited to, results for other periods, passage of time and/or against another company or companies or an index or indices), (iv) on a per-share basis, (v) against the performance of the Company as a whole or a segment of the Company and/or (vi) on a pre-tax or after-tax basis. Prior to the Determination Date, the Administrator shall determine whether any element(s) or item(s) shall be included in or excluded from the calculation of any Performance Goal with respect to any Participants and whether a Performance Goal shall be measured in accordance with generally accepted accounting principles (“GAAP”) or a basis other than GAAP.

(c) Procedures. To the extent necessary to comply with the performance-based compensation provisions of Code Section 162(m), with respect to any Award granted subject to Performance Goals, within the first twenty-five percent (25%) of the Performance Period, but in no event more than ninety (90) days following the commencement of any Performance Period (or such other time as may be required or permitted by Code Section 162(m)), the Administrator will, in writing, (i) designate one or more Participants to whom an Award will be made, (ii) select the Performance Goals applicable to the Performance Period, (iii) establish the Performance Goals, and amounts of such Awards, as applicable, which may be earned for such Performance Period, and (iv) specify the relationship between Performance Goals and the amounts of such Awards, as applicable, to be earned by each Participant for such Performance Period. Following the completion of each Performance Period, the Administrator will certify in writing whether the applicable Performance Goals have been achieved for such Performance Period. In determining the amounts earned by a Participant, the Administrator will have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Administrator may deem relevant to the assessment of individual or corporate performance for the Performance Period. A Participant will be eligible to receive payment pursuant to an Award for a Performance Period only if the Performance Goals for such period are achieved.

(d) Additional Limitations. Notwithstanding any other provision of the Plan, any Award which is granted to a Participant and is intended to constitute qualified performance based compensation under Code Section 162(m) will be subject to any additional limitations set forth in the Code (including any amendment to Section 162(m)) or any regulations and ruling issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Section 162(m) of the Code, and the Plan will be deemed amended to the extent necessary to conform to such requirements.

(a) Incentive Stock Option Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 12(a), Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.

(b) Section 162(m) Limitations. The following limitations shall apply to Awards under the Plan: Subject to adjustment as provided in Section 15, during any Fiscal Year, no Employee will be granted:

(i) Options and/or SARs covering more than a total of 1,000,000 Shares; provided, however, that in connection with his or her initial employment, an Employee may be granted Options and/or SARs covering up to a total of 1,000,000 additional Shares in the Fiscal Year in which his or her service as an Employee first commences;

(ii) Restricted Stock and/or Restricted Stock Units and/or Performance Shares covering more than 1,000,000 Shares; provided, however, that in connection with his or her initial employment, an Employee may be granted Restricted Stock, Restricted Stock Units and/or Performance Shares covering up to a total of 1,000,000 additional Shares in the Fiscal Year in which his or her service as an Employee first commences; and

(iii) Performance Units having a grant date fair value (determined in accordance with U.S. generally accepted accounting principles) greater than $5,000,000; provided, however, that in connection with his or her initial employment, an Employee may be granted additional Performance Units in the Fiscal Year in which his or her service as an Employee first commences having a grant date fair value (determined in accordance with U.S. generally accepted accounting principles) no greater than $10,000,000.

(iv) If an Award is cancelled in the same Fiscal Year in which it was granted (other than in connection with a transaction described in Section 15(c)), the cancelled Award will be counted against the limits set forth in this subsection (a).

(c) Outside Director Limitations. No Outside Director may be granted, in any Fiscal Year, Awards covering more than 100,000 Shares. Awards granted to an individual while he or she was an Employee or Consultant, but not an Outside Director, shall not count for purposes of this limitation.

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, and the numerical Share limits in Section 3 of the Plan.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

(c) Change in Control. In the event of a merger of the Company with or into another corporation or other entity or a Change in Control, each outstanding Award will be treated as the Administrator determines, including, without limitation, that each Award be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator will not be required to treat all Awards similarly in the transaction.

In the event that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period.

For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right

or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control.

Notwithstanding anything in this Section 15(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such earlier time as any tax withholding obligations are due, the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof).

(b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a fair market value equal to the minimum statutory amount required to be withheld or such greater amount as the Administrator may determine if such amount would not have adverse accounting consequences, as the Administrator determines in its sole discretion, or (c) delivering to the Company already-owned Shares having a fair market value equal to the minimum statutory amount required to be withheld or such greater amount as the Administrator may determine if such amount would not have adverse accounting consequences, as the Administrator determines in its sole discretion. The fair market value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

(c) Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan are intended to meet the requirements of Code Section 409A and will be construed and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A.

(a) Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan.

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

(a) Legal Compliance. The granting of Awards and the issuance and delivery of Shares under the Plan shall be subject to all Applicable Laws, rule and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. Shares will not be issued pursuant to the exercise or vesting of an Award unless the exercise or vesting of such Award and the issuance and delivery of such Shares will comply with Applicable Laws, rules and regulations and will be further subject to the approval of counsel for the Company with respect to such compliance

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award 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.
