All eligible stockholders are cordially invited to attend the virtual Annual Meeting. However, to ensure your representation at the meeting, you are urged to vote as promptly as possible to ensure that your vote is recorded.

PROXY STATEMENT

2019 ANNUAL MEETING OF STOCKHOLDERS

INFORMATION CONCERNING SOLICITATION AND VOTING

GENERAL

This proxy statement and the enclosed form of proxy card are furnished in connection with the solicitation of proxies by and on behalf of the Board of Directors (the “Board of Directors” or the “Board”) of Harmonic Inc., a Delaware corporation (“Harmonic,” “we” or the “Company”), for use at the 2019 Annual Meeting of Stockholders and any adjournment(s), postponement(s) or other delays thereof (the “Annual Meeting”) to be held virtually on Wednesday, June 5, 2019, at 10:00 a.m. Pacific Time, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Stockholders. You will be able to attend the Annual Meeting, vote your shares electronically and submit your questions during the live webcast of the meeting by visiting www.virtualshareholdermeeting.com/HLIT2019 and entering your 16-digit control number located on your proxy card.

INTERNET AVAILABILITY OF PROXY MATERIALS

Under rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies of those materials to each stockholder. On or about April 25, 2019, we expect to send to our stockholders (other than those who previously requested electronic or paper delivery) a Notice of Internet Availability of Proxy Materials (the “E-Proxy Notice”) containing instructions on how to access our proxy materials, including our proxy statement (the “Proxy Statement”) and our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “2018 Annual Report”). The E-Proxy Notice also instructs you on how to access your proxy card to vote through the Internet or by telephone.

This process is designed to expedite stockholders’ receipt of proxy materials, lower the cost of the Annual Meeting, and help conserve natural resources. If you previously elected to receive our proxy materials electronically, you will continue to receive these materials via e-mail unless you elect otherwise. However, if you would prefer to receive printed proxy materials, please follow the instructions to receive printed proxy materials included in the E-Proxy Notice.

WHO CAN VOTE AT THE ANNUAL MEETING

Stockholders as of the close of business on April 8, 2019 (the “Record Date”) are entitled to notice of and to vote at the Annual Meeting. As of the Record Date, 88,725,604 shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”), were issued and outstanding.

Stockholder of Record: Shares Registered in Your Name

If, on April 8, 2019, your shares were registered directly in your name with our transfer agent, Computershare Investor Services, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the Annual Meeting or vote by proxy. Whether or not you plan to attend the virtual Annual Meeting, we urge you to vote over the Internet or by telephone, or if you received paper proxy materials by mail, by filling out and returning the proxy card in the enclosed postage-paid envelope.

Beneficial Owner: Shares Registered in the Name of a Broker or Nominee

If, on April 8, 2019, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account, and it has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the Annual Meeting. Because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Annual Meeting.

HOW TO VOTE

If you are a stockholder of record you may vote by proxy or electronically at the Annual Meeting. To vote by proxy, you may vote via the Internet or by telephone by following the instructions provided on the E-Proxy Notice or proxy card, or if you received a paper proxy card and voting instructions by mail, you should sign, date and return the enclosed proxy card in the enclosed postage-paid envelope before the Annual Meeting.

1

If you are a beneficial owner and not the stockholder of record, please refer to the voting instructions provided by your nominee to direct it on how to vote your shares.

REVOCABILITY OF PROXIES

Any proxy may be revoked by the person giving it at any time before its use at the Annual Meeting by delivering to the Secretary of the Company, at the Company’s principal offices at 4300 North First Street, San Jose, California 95134, a written notice of revocation or a signed proxy bearing a later date, or by voting on a later date by telephone or via the Internet. If you attend the virtual Annual Meeting and vote electronically, any previously submitted proxy will be revoked.

Please note, however, that if you are a beneficial owner and you wish to change or revoke your proxy, you may change your vote by submitting new voting instructions to your broker, bank or other nominee in accordance with their operating procedures or, if you have obtained a legal proxy from your broker, bank or other nominee giving you the right to vote your shares at the Annual Meeting, by attending the virtual Annual Meeting and voting electronically.

QUORUM

Each stockholder is entitled to one vote for each share of Common Stock held as of the Record Date on all matters presented at the Annual Meeting. Stockholders do not have the right to cumulate their votes in the election of directors.

The holders of a majority in voting power of the Common Stock issued and outstanding and entitled to vote at the Annual Meeting, present in person or represented by proxy, constitutes a quorum for action at the Annual Meeting. Shares that reflect abstentions and broker non-votes count as present at the Annual Meeting for the purposes of determining a quorum.

VOTING REQUIREMENTS

Majority vote for a Director's election. The Company’s Corporate Governance Guidelines provide that, in the case of an uncontested election (i.e., an election where the number of director nominees is not greater than the number of directors to be elected), a nominee shall be elected by the affirmative vote of the majority of the votes cast by holders of shares present in person or represented by proxy at a meeting for the election of directors at which a quorum is present. For this purpose, the “affirmative vote of the majority of the votes cast” means the number of shares voted “FOR” a director’s election exceeds the number of shares “WITHHELD” with respect to that director’s election. In a contested election (i.e., an election where the number of nominees is greater than the number of directors to be elected), a nominee shall be elected by a plurality of the votes cast.

Majority vote for other Proposals. The advisory vote on named executive officer compensation (Proposal Two in this Proxy Statement), the amendment to the Company’s 2002 Employee Stock Purchase Plan (Proposal Three in this Proxy Statement), the amendment to the Company’s 1995 Stock Plan (Proposal Four in this Proxy Statement), the amendment to the Company's 2002 Director Stock Plan (Proposal Five in this Proxy Statement) and the ratification of the appointment of the Company’s independent registered public accounting firm (Proposal Six in this Proxy Statement) each require the favorable vote of the holders of a majority of the Common Stock having voting power present in person or represented by proxy and entitled to vote on the proposal.

Treatment of abstentions and broker non-votes. In the election of directors (Proposal One in this Proxy Statement), abstentions and broker non-votes will be disregarded and have no effect on the outcome of the vote. With respect to the advisory vote on named executive officer compensation (Proposal Two in this Proxy Statement), the amendment to the Company’s 2002 Employee Stock Purchase Plan (Proposal Three in this Proxy Statement), the amendment to the Company’s 1995 Stock Plan (Proposal Four in this Proxy Statement), the amendment to the Company's 2002 Director Stock Plan (Proposal Five in this Proxy Statement) and the ratification of the appointment of the Company’s independent registered public accounting firm (Proposal Six in this Proxy Statement), abstentions will have the same effect as voting against the proposal and broker non-votes, if any, will be disregarded and have no effect on the outcome of the vote.

Meaning of "broker non-votes." If you hold shares beneficially in street name (that is, in an account at a bank or broker) and do not provide your bank or broker with voting instructions, your shares may constitute “broker non-votes.” Broker non-votes occur on a matter when a bank or broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. These matters are referred to as “non-routine” matters. All of the matters scheduled to be voted on at the Annual Meeting are “non-routine,” except for the ratification of the appointment of the Company’s independent registered public accounting firm (Proposal Five in this Proxy Statement).

SOLICITATION

The Company will bear the cost of soliciting proxies, including the preparation, assembly, Internet hosting, printing and mailing of the E-Proxy Notice, this Proxy Statement, the proxy card and any other proxy materials furnished to stockholders by the Company in connection with the Annual Meeting. In addition, the Company may reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding the proxy materials to such beneficial owners. Solicitation of proxies by

2

mail may be supplemented by telephone, facsimile, email, Internet or personal solicitation by directors, officers, employees or independent contractors of the Company. Other than for any such independent contractors, no additional compensation will be paid to such persons for such services.

BOARD OF DIRECTORS’ VOTING RECOMMENDATION

Proposal One. The Board of Directors recommends that you vote your shares “FOR” each of the Board’s nominees that are standing for election to the Board of Directors.

Proposal Two. The Board of Directors recommends that you vote your shares “FOR” the approval of the advisory vote on named executive officer compensation.

Proposal Three. The Board of Directors recommends that you vote your shares “FOR” the amendment to the Company’s 2002 Employee Stock Purchase Plan.

Proposal Four. The Board of Directors recommends that you vote your shares “FOR” the amendment to the Company’s 1995 Stock Plan.

Proposal Five. The Board of Directors recommends that you vote your shares “FOR” the amendment to the Company’s 2002 Director Stock Plan.

Proposal Six. The Board of Directors recommends that you vote your shares “FOR” the ratification of the appointment of the Company’s independent registered public accounting firm.

IF YOU RECEIVE MORE THAN ONE PROXY CARD OR E-PROXY NOTICE

If you receive more than one proxy card or E-Proxy Notice, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on the E-Proxy Notice on how to access each proxy card and vote each proxy card over the Internet or by telephone. If you received paper proxy materials by mail, please complete, sign and return each proxy card to ensure that all of your shares are voted.

STOCKHOLDER PROPOSAL PROCEDURES AND DEADLINES

3

decrease the voting power of, such stockholder or any associated person of such stockholder with respect to the securities of the Company; (e) any material interest of the stockholder or any associated person of such stockholder in such business; and (f) a statement whether either of such stockholder or any associated person of such stockholder will deliver a proxy statement and form of proxy to holders of at least the percentage of the Company’s voting shares required under applicable law to carry the proposal. In addition, to be in proper written form, a stockholder’s notice to the Secretary of the Company must be supplemented not later than 10 calendar days following the record date to disclose the information contained in clauses (c) and (d) above as of the record date.

PROPOSAL ONE

ELECTION OF DIRECTORS

NOMINEES

Seven (7) directors are to be elected at the Annual Meeting. Each of the directors elected at the Annual Meeting will hold office until the earlier of the 2020 annual meeting of stockholders or until such director’s successor has been elected and qualified or until such director’s earlier resignation or removal. Floyd Kvamme, a current member of our board of directors, will not stand for re-election at the Annual Meeting. The Board thanks Mr. Kvamme for his many years of service to the Company and its stockholders. As a result of the conclusion of Mr. Kvamme's service on the Board, immediately prior to the Annual Meeting, the Company’s bylaws will be amended to reduce the authorized size of the Board to seven.

Unless otherwise instructed, the designated proxy holders will vote the proxies received by them “FOR” the Company’s seven nominees named below, all of whom are currently directors of the Company. Each of the nominees was recommended for election by the Company’s Corporate Governance and Nominating Committee of the Board of Directors (the “Corporate Governance and Nominating Committee”) and the Board of Directors. In the event that any nominee of the Company becomes unable or declines to serve as a director at the time of the Annual Meeting, the designated proxy holders will vote the proxies for any substitute nominee who is designated by the Company’s Corporate Governance and Nominating Committee to fill the vacancy. It is not expected that any nominee listed below will be unable or will decline to serve as a director.

DIRECTOR QUALIFICATIONS

The Board of Directors believes that it is necessary for each of the Company’s directors to possess a broad array of qualities and skills. When searching for new director candidates, the Corporate Governance and Nominating Committee considers the evolving requirements of serving on the Board of Directors and searches for candidates that fill any current or anticipated future requirements. The Board of Directors also believes that all directors must possess a considerable amount of business and management experience and education.

The Corporate Governance and Nominating Committee first considers a candidate’s business and management experience and education and then considers issues of judgment, personal character, integrity, conflicts of interest, diversity and commitment to the goal of maximizing long-term stockholder value. With respect to the nomination of continuing directors for re-election, the individual’s historical and ongoing contributions to the Board of Directors are also considered. Each of the directors nominated to be elected at the Annual Meeting are continuing directors; however, Deborah Clifford is standing for election by stockholders for the first time. The process undertaken by the Corporate Governance and Nominating Committee in recommending qualified director candidates is described below under “Identification and Evaluation of, and Criteria for, Candidates for Board Membership” (see page 10 of this Proxy Statement).

DIRECTOR NOMINEES

The names of the nominees for director and certain information about each of them are set forth below. The information presented includes age as of April 1, 2019, positions held, principal occupation and business experience for at least the past five years, and the names of other publicly-held companies of which the nominee currently serves as a director or has served as a director during the past five years. In addition to the information presented below regarding the nominee’s specific experience, qualifications, attributes and skills that led our Board to the conclusion that each nominee is qualified to serve as a director, we also believe that all of our director nominees have a reputation for integrity, honesty and adherence to high ethical standards. They each have demonstrated knowledge of our industry, an ability to exercise sound judgment, and a commitment to Harmonic and the Board of Directors. Finally, with respect to our directors who have not been officers of the Company, we value their experience on other public company boards of directors and board committees and as senior officers of other companies. Each of the nominees has consented to being named in this Proxy Statement and to serve as a director if elected.

Patrick Gallagher	64	Chairman of Intercloud SAS

BOARD OPERATIONS AND CORPORATE GOVERNANCE

BOARD MEETINGS AND COMMITTEES

The Board of Directors held a total of six (6) meetings during the fiscal year ended December 31, 2018. No director attended fewer than 83% of the meetings of the Board, or the committees upon which such director served, in 2018.

The Board has determined that Messrs. Gallagher, Krall, Kvamme and Theodosopoulos and Mmes. Clifford, Reaugh and Swenson are “independent” as that term is defined under the applicable rules and regulations of the SEC and under applicable NASDAQ listing standards. Mr. Kvamme will not be standing for re-election at the Annual Meeting at his request. In making this determination, the Board considered the current and prior relationships that each non-employee director has with Harmonic and all other facts and circumstances the Board deemed relevant in determining their independence, including the beneficial ownership of the Company’s capital stock by each non-employee director. The independent directors have no relationships with the Company which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The Board has an Audit Committee, a Compensation Committee and a Corporate Governance and Nominating Committee.

Audit Committee

The Audit Committee currently consists of Mr. Theodosopoulos and Mmes. Clifford and Swenson, each of whom is independent under Rule 10A-3 of the Exchange Act and under applicable NASDAQ Stock Market listing standards.

Mr. Theodosopoulos serves as the Chairperson of the Audit Committee. The Audit Committee serves as the representative of the Board for general oversight of the quality and integrity of Harmonic’s financial accounting and reporting process, system of internal control over financial reporting, management of financial risks, audit process, and process for monitoring the compliance with related laws and regulations. Each member of the Audit Committee also meets the financial literacy requirements of the applicable NASDAQ listing standards. The Audit Committee engages the Company’s independent registered public accounting firm and approves the scope of both audit and non-audit services. Matters within the scope of the Audit Committee were also discussed in executive sessions at regularly scheduled meetings of the Board in 2018. The Audit Committee held eleven (11) meetings during 2018.

The Board has determined that Mr. Theodosopoulos is an “audit committee financial expert,” as defined by the current rules of the SEC. The Board believes that Mr. Theodosopoulos’s experience in the communications and finance industries qualifies him as an “audit committee financial expert” because he has acquired relevant expertise and experience from performing his duties as a managing director of technology equity research at a global financial services firm.

The Audit Committee operates under a written charter that was adopted by our board of directors and satisfies the applicable standards of the SEC and applicable NASDAQ listing standards. A copy of our Audit Committee charter is available on our website at www.harmonicinc.com in the Corporate Governance section of the Investor Relations page.

Compensation Committee

The Compensation Committee currently consists of Messrs. Kvamme, Gallagher and Krall and Ms. Reaugh, none of whom is an employee of the Company and each of whom is independent under applicable NASDAQ Stock Market listing standards. Mr. Kvamme will not be standing for re-election at the Annual Meeting and will therefore no longer serve as a member of the Compensation Committee following the Annual Meeting.

Mr. Kvamme currently serves as the Chairperson of the committee. Following the Annual Meeting, Ms. Reaugh has been appointed to serve as the Chairperson of the Compensation Committee. The Compensation Committee is responsible for approving the Company’s compensation policies, compensation paid to executive officers and administration of the Company’s equity compensation plans. The Compensation Committee held six (6) meetings during 2018. Matters within the scope of the Compensation Committee were also discussed in executive sessions at regularly scheduled meetings of the Board in 2018.

The Compensation Committee operates under a written charter that was adopted by our board of directors and satisfies the applicable standards of the SEC and applicable NASDAQ listing standards. A copy of our Compensation Committee charter is available on our website at www.harmonicinc.com in the Corporate Governance section of the Investor Relations page.

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee currently consists of Ms. Swenson and Messrs. Gallagher and Kvamme, each of whom is independent under applicable NASDAQ Stock Market listing standards. Mr. Kvamme will not be standing for re-election at the Annual Meeting and will therefore no longer serve as a member of the Corporate Governance and Nominating Committee following the Annual Meeting. Mr. Krall will join the committee following the Annual Meeting.

8

Ms. Swenson serves as the Chairperson of the Corporate Governance and Nominating Committee. The Corporate Governance and Nominating Committee serves as the representative of the Board for establishment and oversight of governance policy and the operation, composition and compensation of the Board. The Corporate Governance and Nominating Committee held four (4) meetings in 2018. Matters within the scope of the Corporate Governance and Nominating Committee were discussed in executive sessions at regularly scheduled meetings of the Board in 2018.

The Corporate Governance and Nominating Committee has proposed, and the Board has approved, the nomination of seven (7) of the current board members for re-election by stockholders at this Annual Meeting.

The Corporate Governance and Nominating Committee operates under a written charter that was adopted by our board of directors and satisfies the applicable standards of the SEC and applicable NASDAQ listing standards. A copy of our Corporate Governance and Nominating Committee charter is available on our website at www.harmonicinc.com in the Corporate Governance section of the Investor Relations page.

BOARD LEADERSHIP

We separate the roles of Chief Executive Officer (“CEO”) and Chairman of the Board in recognition of the differences between the two roles. The CEO is responsible for setting the strategic direction of the Company and for its operational management, leadership and performance, while the independent Chairman of the Board provides guidance to the CEO and sets the agenda for, and presides over, meetings of the full Board.

MEETINGS OF NON-EMPLOYEE DIRECTORS

At each regularly scheduled Board meeting, the non-employee directors meet in an executive session without any members of management or employees present. The Chairman of the Board has the responsibility of presiding over such periodic executive sessions of the Board. Last year, the non-employee directors discussed, in executive sessions, corporate strategy, risk oversight, management performance, Board performance, succession planning for management and the directors, and Board policies, processes and practices.

CORPORATE GOVERNANCE GUIDELINES

The Board has adopted Corporate Governance Guidelines that set forth the key functions of the Board, as well as principles regarding board structure and composition, director voting, board operations and meetings, board interaction with management and third parties, board committees and director compensation. The Corporate Governance Guidelines, in conjunction with our certificate of incorporation, Bylaws and Board committee charters, form the framework for the governance of the Company.

The Corporate Governance Guidelines are available on the Company’s website at www.harmonicinc.com in the Corporate Governance section of the Investor Relations page. The Corporate Governance Guidelines are reviewed at least annually by our Corporate Governance and Nominating Committee, and changes are recommended to our Board for approval as appropriate.

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a Code of Business Conduct and Ethics that applies to all of our Board members, officers and employees, which is available on the Company’s website at www.harmonicinc.com in the Corporate Governance section of the Investor Relations page. Any amendments or waivers of the code pertaining to a member of our Board or one of our executive officers will be disclosed on our website at the above-referenced address.

ROLE OF THE BOARD IN RISK OVERSIGHT

Management of the Company is responsible for the day-to-day management of risks the Company faces, while the Board has responsibility, as a whole and also at the committee level, for the oversight of the Company’s risk management. The Board regularly reviews the Company’s long-term business strategy, including industry trends and their potential impact on the Company, our competitive positioning, potential acquisitions and divestitures, as well as the Company’s technology and market direction. The Board also reviews information regarding the Company’s actual and planned financial position and operational performance, as well as the risks associated with each. The Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation and the Company’s incentive, equity award and other benefit plans. The Audit Committee oversees management of financial risks, including, but not limited to, accounting matters, tax positions, insurance coverage and security of the Company’s cash reserves. The Corporate Governance and Nominating Committee manages risks associated with the independence and remuneration of the Board and potential conflicts of interest.

At periodic meetings of the Board and its committees, management reports to, and seeks the guidance of, the Board and its committees with respect to the most significant risks that could affect our business. While each committee is responsible for

9

evaluating certain risks and overseeing the management of such risks, the entire Board is periodically informed about such risks by committee reports and receives advice and counsel with respect to risk issues from the Company’s outside counsel.

IDENTIFICATION AND EVALUATION OF, AND CRITERIA FOR, CANDIDATES FOR BOARD MEMBERSHIP

Pursuant to the charter of the Corporate Governance and Nominating Committee, the Committee may utilize a variety of methods to identify and evaluate candidates for service on our Board of Directors. Candidates may come to the attention of the Corporate Governance and Nominating Committee through current directors, management, professional search firms, stockholders, outside professionals or other persons. Any candidate presented would be evaluated at a meeting of the Corporate Governance and Nominating Committee or at a regular Board meeting and may be considered at any point during the year. The Corporate Governance and Nominating Committee may take such measures as it considers appropriate in connection with its evaluation of a candidate, including candidate interviews, inquiry of the person recommending the candidate or reliance on the knowledge of the members of the Corporate Governance and Nominating Committee, members of the Board or management. The Corporate Governance and Nominating Committee has hired, from time to time, a consulting firm to assist it in identifying and screening potential candidates for election to the Board. In evaluating a candidate, the Corporate Governance and Nominating Committee may consider a variety of criteria. These criteria include demonstrated relevant business and industry experience, particular expertise to act as a committee chair or member, the ability to devote the necessary time to the Board and committee service, personal character and integrity, potential conflicts of interest and sound business judgment. The Corporate Governance and Nominating Committee seeks nominees with a broad diversity of experiences, professions, skills, geographic representation and backgrounds, including racial, ethnic and gender diversity.

The Corporate Governance and Nominating Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. Some of the qualifications that the Corporate Governance and Nominating Committee considers include, without limitation, character, integrity, ethics, judgment, diversity of experience, independence, relevant areas of expertise, corporate and technology experience, proven achievement, operating executive experience, understanding of our industry, length of service, potential conflicts of interest and other commitments. The Corporate Governance and Nominating Committee evaluates these factors, among others, and does not assign any particular weighting or priority to any of these factors. The Corporate Governance and Nominating Committee requires the following minimum qualifications to be satisfied by any nominee for a position on the Board of Directors: the highest personal and professional ethics and integrity; proven achievement and competence in the nominee's field and the ability to exercise sound business judgment, as well as skills that are complementary to those of the existing Board; the ability to assist and support management and make significant contributions to our success; and an understanding of the fiduciary responsibilities that are required of a member of the Board and the commitment of time and energy necessary to diligently carry out those responsibilities. The Corporate Governance and Nominating Committee may also consider such other factors as it may deem, from time to time, are in our and our stockholders' best interests. The Board believes that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board to best fulfill its responsibilities. Nominees are not discriminated against on the basis of race, religion, national origin, gender, age, sexual orientation, disability or any other basis proscribed by law. The Corporate Governance and Nominating Committee has not set either term limits or age limits for members of the Board, believing that the Company’s interests are best served by members of the Board with substantial experience and knowledge of the Company’s business and that age is generally not a barrier to effective performance as a member of the Board.

DIRECTOR RECOMMENDATIONS AND NOMINATIONS FROM STOCKHOLDERS

The Corporate Governance and Nominating Committee will consider recommendations from stockholders of individuals for service on the Board of Directors at the 2020 annual meeting of stockholders, provided that such recommendations are submitted in a timely manner in writing to the Corporate Secretary of the Company at Harmonic Inc., 4300 North First Street, San Jose, California 95134. If a stockholder desires to recommend an individual for consideration by the Corporate Governance and Nominating Committee for nomination by the Board, such recommendation must be received no later than December 27, 2019, which is 120 calendar days prior to the first anniversary of the date of this Proxy Statement first became available to stockholders. In evaluating director candidates recommended by stockholders, the Corporate Governance and Nominating Committee will use the same criteria as it uses to evaluate all prospective members of the Board.

For a stockholder nomination of a person for election to the Board at the 2019 annual meeting of stockholders that such stockholder does not desire to have considered by the Corporate Governance and Nominating Committee for nomination by the Board, timely written notice of such nomination must be delivered to the Corporate Secretary of the Company no earlier than March 7, 2020 and no later than April 6, 2020.

To be in proper written form, a stockholder’s notice must contain: (i) as to each person whom the stockholder proposes to nominate for election or re-election as a director, (a) the name, age, business address and residence address of the nominee, (b) the principal occupation or employment of the nominee, (c) the class and number of shares of the Company which are beneficially owned by the nominee and any derivative positions held or beneficially held by the nominee, (d) whether, and the extent to which, any hedging or other transaction or series of transactions has been entered into by or on behalf of the nominee with respect to any

10

securities of the Company, and a description of any other agreement, arrangement or understanding, the effect or intent of which is to mitigate loss, manage the risk or benefit from share price changes, or increase or decrease the voting power of the nominee with respect to any securities of the Company, (e) a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nominations are to be made by the stockholder, (f) a written statement executed by the nominee acknowledging that, as a director of the Company, the nominee will owe fiduciary duties under Delaware law with respect to the Company and its stockholders, and (g) any other information relating to the nominee 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, the nominee’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and (ii) as to such stockholder proposing a nominee for election to the Board, (a) the information set forth in “Stockholder Proposal Procedures and Deadlines” on page 3 of this Proxy Statement for a stockholder notice of business to be brought before an annual meeting, and (b) a statement whether either such stockholder or any associated person of such stockholder will deliver a proxy statement and form of proxy to holders of a number of the Company’s voting shares reasonably believed by such stockholder or associated person of such stockholder to be necessary to elect such nominee. A copy of the full text of the provisions of the Bylaws provisions discussed herein may be obtained by writing to Harmonic Inc., 4300 North First Street, San Jose, California 95134, Attention: Corporate Secretary, or can be accessed from the Company’s filings with the SEC at www.sec.gov.

COMPENSATION OF DIRECTORS

As compensation for its non-employee directors, Harmonic uses a combination of cash and equity-based incentive compensation. Directors who are employees of the Company do not receive additional compensation for their service as directors.

The current non-employee director compensation program was developed in consultation with Compensia, Inc. (“Compensia”), an independent compensation consulting firm. Compensia provided recommendations and competitive non-employee director compensation data and analyses. The Corporate Governance and Nominating Committee considered and discussed these recommendations and data, and considered the specific duties and committee responsibilities of particular directors. The Corporate Governance and Nominating Committee recommended, and the Board of Directors adopted Compensia's recommendations when it approved the non-employee director compensation program described below, which we believe provides our non-employee directors with reasonable and appropriate compensation that is commensurate with the services they provide and competitive with compensation paid by our peers to their non-employee directors.

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

Cash Compensation. Each non-employee director is paid an annual retainer of $35,000. In addition, the Chair of the Audit Committee is paid an annual retainer of $32,000, the Chair of the Compensation Committee is paid an annual retainer of $18,000, and the Chair of the Corporate Governance and Nominating Committee is paid an annual retainer of $11,000. Other members of the Board committees receive an annual retainer as follows: Audit Committee — $16,000; Compensation Committee — $9,000; and Corporate Governance and Nominating Committee — $5,500. The non-executive Chairman of the Board receives an additional annual retainer of $40,000. No additional fees are paid for attending in-person or telephonic meetings of the Board or its committees.

Equity Compensation. The 2002 Director Stock Plan, as amended (the “2002 Plan”), currently provides for grants of stock options or restricted stock units (“RSUs”) to be made in three ways:

• Initial Grants. Each new non-employee director who joins the Board (excluding a former employee director who ceases to be an employee director, but who remains a director) is entitled to receive stock options or RSUs, or a mix thereof, on the date that the individual is first appointed or elected to the Board, as determined by the Board in its sole discretion. Under the Company’s current non-employee director compensation program as recommended by Compensia, a new non-employee director will receive an RSU award with a grant date value of $165,000 that vests in equal annual installments over 3 years.

• Ongoing Grants. Each non-employee director who has served on the Board for at least six months, as of the date of grant, will receive an annual grant of stock options or RSUs, or a mix thereof, as determined by the Board in its sole discretion. Ongoing grants have historically been made in the first quarter of each fiscal year and have been comprised of only RSUs. Under the Company’s current non-employee director compensation program, non-employee directors receive an RSU award with a grant date value of $120,000 that vests in full after 1 year.

• Discretionary Grants. The Board may make discretionary grants of stock options or RSUs, or a mix thereof, to any non-employee director.

NON-EMPLOYEE DIRECTOR STOCK OWNERSHIP POLICY

Under the Board's non-employee director stock ownership policy, each non-employee director is required to beneficially own shares of Common Stock with a market value equal to at least $175,000 (excluding, for the purposes of this calculation, the value of stock options exercisable within 60 days) by the later of the Company’s 2018 annual meeting of stockholders or the fifth anniversary of the director’s election to the Board. Each non-employee director is in compliance with these guidelines or is on track to be in compliance with these guidelines by the applicable deadline.

COMMUNICATION WITH THE BOARD OF DIRECTORS

The Board believes that management should be the primary means of communication between the Company and all of its constituencies, including stockholders, customers, suppliers and employees. However, stockholders may communicate with individual members of the Board, committees of the Board, or the full Board by addressing correspondence to Harmonic Inc., 4300 North First Street, San Jose, California 95134. Attention: Corporate Secretary. Our Corporate Secretary or legal department, in consultation with appropriate members of the Board as necessary, will review all incoming communications and, if appropriate, such communications will be forwarded to the appropriate member or members of our Board.

ATTENDANCE OF THE BOARD OF DIRECTORS AT ANNUAL MEETINGS

Five members of the Board attended the Company’s 2018 virtual annual meeting telephonically. The Board has a policy encouraging directors to attend annual stockholder meetings.

PROPOSAL TWO

ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

Pursuant to Section 14A of the Exchange Act of 1934 as promulgated by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we are asking stockholders to vote on the compensation of our named executive officers (the “NEOs”), as named in accordance with applicable SEC rules, on page 42 of this Proxy Statement. This Proposal Two, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our NEOs’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our NEOs and the named executive officer compensation philosophy, policies and practices described in this Proxy Statement.

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee or the Board. The say-on-pay vote will, however, provide information to us regarding investor sentiment about our named executive officer compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining named executive officer compensation for the remainder of the current fiscal year and for future fiscal years. Our Board and Compensation Committee value the opinions of our stockholders, and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and the Compensation Committee will evaluate whether any action is necessary to address those concerns. At our 2018 annual meeting, our stockholders approved the compensation of our NEOs, with approximately 98% of the shares present and entitled to vote voting in favor of the say-on-pay proposal. As we evaluated our compensation practices and talent needs throughout 2018, we were mindful of the support our stockholders expressed for our philosophy of linking compensation to our financial goals and in support of enhancing stockholder value. As a result, the Compensation Committee decided to retain our general approach with respect to our named executive officer compensation programs, with an emphasis on delivering long-term and short-term incentive compensation that reward our executives commensurate with the value they deliver to our stockholders. Since 2011, we have held an advisory vote to approve named executive officer compensation each year, and the next such advisory vote will occur at our 2020 annual meeting.

The Company’s goal for its named executive officer compensation program is to attract, motivate and retain a talented and creative team of executives who will contribute significantly to the long-term success of the Company and the enhancement of stockholder value. As described in the “Compensation Discussion and Analysis” and “Executive Compensation” sections beginning on pages 34 and 42, respectively, of this Proxy Statement, we believe that our named executive officer compensation program was designed appropriately and is working to ensure management’s interests are aligned with our stockholders’ interests to support long-term value creation. We would like to highlight the following items that support these beliefs:

• Our Compensation Committee retains an independent compensation consultant to assist it in the evaluation of appropriate cash and equity compensation for executive management.

• The compensation philosophy of our Compensation Committee includes relating each of the individual components of executive management compensation to overall Company performance.

PROPOSAL THREE

APPROVAL OF AMENDMENT TO HARMONIC’S 2002 EMPLOYEE STOCK PURCHASE PLAN

The Company’s stockholders are being asked to approve a 1,000,000 share increase in the number of shares of Common Stock reserved for issuance under the Company’s 2002 Employee Stock Purchase Plan (the “ESPP”).

The ESPP was adopted by the Board of Directors in March 2002 and was approved by our stockholders in May 2002. The ESPP, as initially approved, permitted the issuance of 1,500,000 shares of Common Stock. Amendments to the ESPP, adopted in May 2004, May 2006, May 2009, July 2011, August 2013, July 2014, June 2016, June 2017 and June 2018, increased the maximum number of shares available for issuance under the ESPP by an additional 14,300,000 shares in the aggregate, resulting in 15,800,000 shares of Common Stock permitted for issuance under the ESPP. As of March 31, 2019, there were 754,095 shares of Common Stock currently available for issuance under the ESPP.

In April 2019, the Board of Directors unanimously approved an amendment to the ESPP, subject to obtaining stockholder approval, to increase the number of shares of Common Stock available for issuance under the ESPP by 1,000,000 shares. If this proposal is approved by our stockholders, the shares reserved and available for issuance under the ESPP for the current offering period and for offering periods commencing on or after July 1, 2019, would be increased by 1,000,000 shares. Based on the Company’s current forecasts and estimated participation rates, the Company expects that with this increase, the ESPP will have enough shares of Common Stock to cover ESPP purchases through July 2020.

If this proposal is not approved by the Company’s stockholders, the shares reserved and available for issuance under the ESPP will be 754,095, and, based on current forecasts and estimated participation rates, the Company anticipates this would only be enough shares of Common Stock to cover ESPP purchases through July 2019.

The intent of the ESPP is to encourage employees to acquire equity ownership in the Company in an effort to ensure a close alignment of the interests of employees with those of the Company’s stockholders. The proposed increase in the number of shares available for issuance under the ESPP will enable the Company to continue to use the ESPP as a valuable tool for attracting and retaining key personnel and aligning the interests of ESPP participants with those of the Company’s stockholders. We believe that the ESPP remains an important element of a competitive compensation package, especially for technology companies, as these plans are offered by most public companies with which we compete for employees. Approximately 45% of our employees eligible to participate in the ESPP during the offering period ending July 1, 2019 are participating.

DESCRIPTION OF EMPLOYEE STOCK PURCHASE PLAN

The following is a summary of the principal features of the ESPP and its operation. This summary is qualified in its entirety by reference to the ESPP.

Purpose. The purpose of the ESPP is to provide employees with an opportunity to purchase Common Stock through payroll deductions.

Administration. The ESPP is administered by the Board of Directors or a committee appointed by the Board of Directors (in either case, the “Administrator”). The Administrator has full and exclusive discretionary authority to construe, interpret and apply the terms of the ESPP, and the Administrator’s findings, decisions, and determinations are final and binding upon all parties.

Eligibility. Currently, each of our employees, and each employee of our designated subsidiaries, whose customary employment with the Company or the designated subsidiary is at least 20 hours per week and more than five months in any calendar year, is eligible to participate in the ESPP. As of the beginning of the current offering period on January 1, 2019, approximately 1,105 employees were eligible to participate in the ESPP. No employee who owns stock and/or holds outstanding options to purchase stock that is equal to or greater than 5% of the total combined voting power or value of all classes of our stock may participate in the ESPP. Moreover, no employee may participate to the extent that he or she may purchase Common Stock under all employee stock purchase plans of the Company with a fair market value (determined on the first day of any offering period) in excess of $25,000 in any calendar year.

Shares Available for Issuance. As of March 31, 2019, there were 754,095 shares of Common Stock available for issuance under the ESPP, most of which are expected to be issued on the next purchase date on July 2, 2019, after the end of the current offering period. If our stockholders approve this proposal, an additional 1,000,000 shares will become reserved and available for issuance in the current offering period and for offering periods commencing on or after July 1, 2019.

Offering Period. The ESPP currently has offering periods that have a duration of approximately six months, commencing on the first trading day for Common Stock on or after each January 1 and July 1 and terminating on the last trading day of the period ending approximately six months thereafter. Our Board of Directors has the power to change the commencement date and the duration of future offering periods without stockholder approval, if such change is announced prior to the scheduled beginning of

15

the first offering period to be affected by such change. Each offering period constitutes a purchase period during which shares of Common Stock may be purchased on behalf of the participant in accordance with the terms of the ESPP.

Participation. To participate in the ESPP, an eligible employee must authorize payroll deductions pursuant to the ESPP. Payroll deductions are withheld only in whole percentages of the participant’s compensation and cannot exceed 10% of a participant’s compensation that she or he receives on each pay day during the offering period.

A participant may not make any additional payments into her or his account other than by payroll deductions. To the extent necessary to comply with Section 423(b)(8) of the Internal Revenue Code of 1986, as amended (the “Code”), and eligibility limitations pursuant to the ESPP, a participant’s payroll deductions may be decreased to zero by the participant at any time during an offering period. A participant may decrease, but not increase, the rate of payroll deductions during an offering period, except the Administrator may, in its discretion, limit the nature and/or number of participant rate changes during any offering period.

Grant. The number of shares of Common Stock a participant purchases in each offering period is determined by dividing the total amount of payroll deductions withheld from the participant’s compensation during the offering period by the purchase price. However, a participant may purchase no more than 1,500 shares in any offering period.

Purchase Price; Exercise. The Internal Revenue Service views participants in our ESPP as receiving options. The price per share of the shares subject to the option, as permitted by the Code, is the lower of (i) 85% of the fair market value of a share of Common Stock on the first day of the offering period, or (ii) 85% of the fair market value of a share of Common Stock on the purchase date, which is the last day of the offering period. Unless a participant withdraws from the ESPP or her or his employment terminates with us or a designated subsidiary, the participant’s option for the purchase of shares is exercised automatically on each purchase date. No fractional shares may be purchased, and any accumulated payroll deductions not sufficient to purchase a full share are retained in the participant’s account for the subsequent offering period.

If the number of shares with respect to which options are to be exercised exceed shares available for sale under the ESPP on a purchase date or commencement of an offering period, the Administrator may, in its sole discretion, make a pro rata allocation of the shares available for purchase and either continue the offering period then in effect or terminate the offering period then in effect. The Administrator may make such pro rata allocation of shares notwithstanding any authorization of additional shares for issuance under the ESPP by our stockholders subsequent to the commencement of an offering period.

Withdrawal; Termination of Employment. A participant may withdraw all, but not less than all, the payroll deductions credited to her or his account, and not yet used to exercise her or his option, under the ESPP at any time by written notice to the Company. If a participant withdraws from an offering period, no further payroll deductions by the participant will be made during the offering period and payroll deductions will not automatically resume at the beginning of the succeeding offering period. Additionally, payroll deductions credited to the participant’s account during the offering period, but not yet used to exercise the option, will be returned to the participant or, in the case of her or his death, to the person or persons entitled thereto, and the participant’s option will automatically terminate. Withdrawal from an offering period has no effect upon a participant’s eligibility to participate in subsequent offering periods. If a participant fails to remain as our employee or an employee of a designated subsidiary, or ceases to meet the ESPP eligibility requirements, she or he is deemed to have withdrawn from the ESPP.

Adjustments upon Changes in Capitalization and Certain Transactions. Any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, payment of a stock dividend, or any other increase or decrease in the number of shares of Common Stock effected without the Company receiving consideration will proportionately adjust the:

1. number of shares of Common Stock covered by each ESPP option;

2. number of shares of Common Stock each participant may purchase in an offering period;

3. number of shares of Common Stock available for sale under the ESPP; and

4. price per share of Common Stock covered by each ESPP option.

Any other issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, will not affect the number or price of shares of Common Stock subject to an ESPP option.

In the event of a proposed dissolution or liquidation of the Company, an offering period will be shortened by setting a new purchase date, and terminated immediately prior to the consummation of the proposed dissolution or liquidation, unless the Administrator provides otherwise.

In the event of a merger or change of control of the Company, each outstanding option under the ESPP will be assumed or an equivalent option substituted by the successor corporation or a parent or subsidiary of the successor corporation. If the successor corporation refuses to assume, or substitute for, the option, any offering period then in progress under the ESPP is shortened by

16

setting a new purchase date and terminated before the date of the proposed merger or change of control. The Administrator will notify each participant in writing prior to the new purchase date that her or his option will be automatically exercised on the new purchase date, unless prior to such date the participant has withdrawn from the offering period.

Amendment or Termination. The Administrator may, at any time and for any reason, terminate or amend the ESPP, except that no terminations can affect options previously granted, other than certain terminations specified in the ESPP. Without stockholder approval and without regard to whether any participant rights may be considered to have been adversely affected, the Administrator is entitled to:

1. change the offering periods;

2. limit the frequency and number of changes in the amount withheld during an offering period;

3. establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars;

4. permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in our processing of properly completed withholding elections;

5. establish reasonable waiting and adjustment periods and accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock properly correspond with amounts withheld; and

6. establish such other limitations or procedures as the Administrator determines, in its sole discretion, to be advisable and which are consistent with the ESPP.

In the event the Administrator determines that the ongoing operation of the ESPP may result in unfavorable financial accounting consequences, the Board may, in its discretion, without stockholder approval or the consent of any participant, and to the extent necessary or desirable, modify or amend the ESPP to reduce or eliminate such accounting consequence, including, without limitation, by (i) increasing the purchase price for any offering period, including an offering period underway at the time of Board action, (ii) shortening any offering period so that offering period ends on a new purchase date, including an offering period underway at the time of the Board action, and (iii) allocating shares.

NUMBER OF SHARES PURCHASED BY CERTAIN INDIVIDUALS AND GROUPS

Given that the number of shares that may be purchased under the ESPP is determined, in part, by the Common Stock’s market value at the beginning and end of each offering period (or upon a purchase date within an offering period), and given that participation in the ESPP is voluntary on the part of employees, the actual number of shares that may be purchased by any individual is not determinable. For illustrative purposes, the following table sets forth (a) the number of shares of Common Stock that were purchased under the ESPP during fiscal year 2018 by our NEOs, as a group, and by our employees who are not NEOs, as a group, and (b) the weighted average per share purchase price paid for such shares by each such group.

	ESPP Transactions 2018
	Number of Shares Purchased		Weighted Average Purchase Price
All named executive officers as a group (5 persons)	6,000	$	3.57
All employees, other than named executive officers, as a group (567 persons)(1)	1,132,438	$	3.57

(1) We had 1,162 employees as of December 31, 2018, 53 of which were not eligible to participate in the ESPP due to being located in countries where the Company does not offer the ESPP.

TAX ASPECTS

The following brief summary of the effect of U.S. federal income taxation upon a participant and the Company with respect to the shares purchased under the ESPP does not purport to be complete, and does not discuss such tax consequences with respect to a participant’s death or the income tax laws of any state or foreign country in which the participant may reside.

The ESPP, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Sections 421 and 423 of the Code. Under these provisions, an employee will not have taxable income when the shares of Common Stock are purchased, but the employee generally will have taxable income when the employee sells or otherwise disposes of shares purchased under the ESPP.

Upon sale or other disposition of the shares, the participant will generally be subject to tax in an amount that depends upon the holding period. If the shares are sold or otherwise disposed of more than two years from the first day of the applicable offering

17

period and one year from the applicable purchase date, the participant will recognize ordinary income measured as the lesser of (a) the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price, or (b) an amount equal to 15% of the fair market value of the shares as of the first day of the applicable offering period. Any additional gain will be treated as long-term capital gain. If the shares are sold or otherwise disposed of before the expiration of either of these holding periods, the participant will recognize ordinary income generally measured as the excess of the fair market value of the shares, on the date the shares are purchased, over the purchase price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on how long the shares have been held from the purchase date. The Company generally is not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant, except to the extent of ordinary income recognized by participants upon a sale or disposition of shares prior to the expiration of the holding periods described above.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING “FOR” THE APPROVAL OF THE PROPOSED AMENDMENT TO THE 2002 EMPLOYEE STOCK PURCHASE PLAN.

PROPOSAL FOUR

APPROVAL OF AMENDMENT TO HARMONIC’S 1995 STOCK PLAN

The Company’s stockholders are being asked to approve an amendment to the 1995 Stock Plan (the “1995 Plan”) which would (i) increase the number of shares of common stock reserved for issuance under the 1995 Plan by 3,500,000 shares, (ii) prospectively reduce the amount of shares of Common Stock debited from the 1995 Plan with respect to restricted stock units (“RSUs”) to one share for every share subject to an RSU, (iii) increase the individual grant limits per fiscal year to 800,000 shares of Common Stock for stock options and stock appreciation rights (“SARs) and 800,000 shares of Common Stock for awards of RSUs and performance shares and (iv) due to recent changes in the U.S. federal tax laws, eliminate certain provisions that were in the 1995 Plan only to allow us the ability to grant awards under the 1995 Plan intended to satisfy the requirements of the “performance-based” compensation exception under Section 162(m) of the Code, which because of such tax law changes are now moot.

The 1995 Plan is the only equity plan of the Company available for grant of equity awards to employees and consultants of the Company. As of April 16, 2019, options to purchase an aggregate of 2,558,558 shares of the Company’s common stock were outstanding under the 1995 Plan, with a weighted average exercise price of $5.79 per share and a weighted average term of 2.4 years. In addition, a total of 3,224,519 RSUs issued under the 1995 Plan had not yet vested. As of April 16, 2019, 2,087,587 shares were available for future grant under the 1995 Plan (excluding the 3,500,000 shares discussed in this proposal and subject to approval at the Annual Meeting). Under the terms of the 1995 Plan, as amended, each award of RSUs granted prior to June 5, 2019 will debit the 1995 Plan 1.5 shares and each award of RSUs granted on or after June 5, 2019 will debit the 1995 Plan one share for every share subject to the RSU.

If this share increase is not approved, then the remaining shares available for grants under the 1995 Plan will be insufficient to meet the Company’s grant needs for new employee, ongoing employee and consultant grants for the remainder of 2019 and beyond.

Equity Plan Information as of April 16, 2019
Shares available for grant under all active equity plans (i.e., 1995 Plan and 2002 Director Stock Plan):	2,508,249
Stock options outstanding under all active and inactive equity plans:	2,682,235
Weighted average term of outstanding stock options under all active and inactive equity plans:	2.35 years

(1 ) The number of performance-based RSUs vested is corrected from the number reported in our Form 10-Ks filed with the U.S. Securities and Exchange Commission on March 5, 2018 and March 1, 2019, which reported that 610,579 performance-based RSUs vested.

Based on the data shown above, if grants during 2019 are made according to the historical average, it is likely that there would be insufficient shares available in the 1995 Plan to meet our regular grant needs through the end of 2019 and beyond.

Proposed Amendments

The 1995 Plan currently permits us to grant a broad range of equity awards to eligible employees and consultants of the Company. We established the 1995 Plan in order to assist the Company in attracting, retaining and motivating the best available personnel for the successful conduct and growth of the Company’s business. The Company believes that the 1995 Plan is an essential tool to link the long-term interests of stockholders and employees and serves to motivate its officers and other employees to make decisions that will, in the long run, give the best returns to stockholders. The Company has, therefore, consistently included equity incentives as a significant component of compensation for a broad range of the Company’s employees. In addition, the Company believes this practice is critical to the Company’s ability to attract and retain employees in highly competitive markets for managerial and technical talent. The Company’s key sites in California (Silicon Valley), Israel, Hong Kong, France and certain other locations exposes it to particularly intense competition in the labor market from both private and public companies. Equity incentives are offered by most companies with which the Company competes for employees, and the Company believes it is essential to provide RSUs to both new and existing employees.

In April 2019, our Board of Directors approved amending the 1995 Plan, subject to stockholder approval at the Annual Meeting. The proposed amendment would increase the number of shares reserved for issuance under the 1995 Plan by 3,500,000 shares and based on the data available as of April 16, 2019, the additional shares would increase the total number of shares available for grant under the 1995 Plan to 5,587,587.

20

The proposed amendment would, with respect to RSUs granted under the 1995 Plan on or after June 5, 2019, reduce the number of shares debited against the 1995 Plan share reserve to 1 share for every RSU and conversely return 1 share to the 1995 Plan reserve for any RSU to the extent forfeited. Any RSU awards that previously debited 1.5 shares against the 1995 Plan share reserve for every RSU will continue to return 1.5 shares to the 1995 Plan reserve for each forfeited RSU. This change is being made consistent with the changes requested under proposal five with respect to the 2002 Plan.

The proposed amendment would increase the individual grant limits per fiscal year to 800,000 shares of Common Stock for stock options and SARs and 800,000 shares for RSU and performance share awards. Prior to amendment, there were individual grant limits per fiscal year of 600,000 shares for stock options and SARs and separate annual limits of 200,000 shares apiece for RSUs and performance shares.

Finally, due to the elimination of the “performance-based” compensation exception under Section 162(m) of the Code by the Tax Cuts and Jobs Act of 2017 (“TCJA”), the proposed amendment removes certain provisions that allowed us the ability to grant awards under the 1995 Plan intended to satisfy the requirements of that exception to the $1 million annual compensation deduction limitation under Section 162(m) of the Code. These provisions are no longer relevant following the recent amendment to Section 162(m) of Code.

The 1995 Plan retains the ability to grant awards based on the achievement of performance goals in the discretion of the Compensation Committee. The 1995 Plan amendment also retains the same annual award limits as currently in effect, which limits were originally instituted to facilitate compliance with the requirements to grant “performance-based” compensation under Section 162(m) of the Code. We believe that maintaining these limits is important and consistent with current best practices in compensation governance.

The NEOs have an interest in this proposal as they may receive awards under the 1995 Plan from time to time.

The following is a summary of the principal features of the 1995 Plan and its operation. This summary is qualified in its entirety by reference to the 1995 Plan. A copy of the 1995 Plan is provided as Appendix A to this proxy statement.

Purposes

The purposes of the 1995 Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to employees and consultants, and to promote the success of the Company’s business.

Term

The 1995 Plan will expire on March 1, 2025.

Types of Awards

The 1995 Plan provides for the grant of options to purchase shares of our Common Stock, SARs, RSUs, performance shares (“Performance Shares”), performance units (“Performance Units”) and deferred stock units (“Deferred Stock Units”) to employees and consultants of the Company. As of April 16, 2019, there were 1,119 employees (including officers) eligible to participate in the 1995 Plan. Options granted under the 1995 Plan may either be “incentive stock options”, as defined in Section 422 of the Code, or nonstatutory stock options.

Administration

The 1995 Plan may be administered by our Board of Directors or the Compensation Committee. Subject to the other provisions of the 1995 Plan, the administrator has the authority to: (i) construe and interpret the 1995 Plan and awards and apply their provisions; (ii) prescribe, amend or rescind rules and regulations relating to the 1995 Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws; (iii) select the consultants and employees to whom awards are to be granted; (iv) subject to fiscal year limits, applicable to each type of award, for aggregate grants of shares to any participant, determine the number of shares to be made subject to each award; (v) determine whether and to what extent awards are to be granted; (vi) prescribe the terms and conditions of each award (including the provisions of the award agreement to be entered into between the Company and the grantee) including any restrictions; (vii) determine the fair market value of the common stock; (viii) approve the forms of agreements for use under the Plan; (ix) allow participants to satisfy required withholding tax obligations by election to have the Company withhold from the shares or cash issued upon exercise or vesting of an award not in excess of the maximum statutory amount ; (x) amend any outstanding award subject to applicable legal restrictions, except for the reduction of the exercise price of an option or SAR (unless stockholder

21

approval is obtained); (xi) authorize any person to execute, on behalf of the Company, any instrument required to effect the grant of an award; and (xii) subject to certain limitations, take any other actions deemed necessary or advisable for the administration of the 1995 Plan. All decisions, interpretations and other actions of the Compensation Committee shall be final and binding on all holders of options or rights and on all persons deriving their rights from such holders. Shares used to pay the withholding tax related to an award or to pay for the exercise price of an award are not available for future grant or sale under the 1995 Plan.

Eligibility

The 1995 Plan provides that awards may be granted to the Company’s employees and consultants. Incentive stock options may be granted only to employees.

Annual Award Limitations

As amended, the 1995 Plan provides that no participant may be granted, in any fiscal year of the Company, options and SARs that relate to more than 800,000 shares of common stock. The amended 1995 Plan also provides that no participant may be granted, in any fiscal year of the Company, awards of RSUs and performance shares that relate to more than a combined 800,000 shares of common stock.

Terms and Conditions of Options

Our Board of Directors or the Compensation Committee, subject to the provisions of the 1995 Plan, shall have complete discretion to determine the terms and conditions of options granted under the 1995 Plan. Each option granted under the 1995 Plan is evidenced by a written stock option agreement between the optionee and the Company and is subject to other terms and conditions, as set forth below.

Exercise Price. Our Board of Directors or the Compensation Committee determines the exercise price of options at the time the options are granted. However, the exercise price of any stock option must not be less than 100% of the fair market value of the common stock on the grant date. Options may be granted with a per share exercise price of less than 100% of the fair market value per share on the date of grant pursuant to a merger or other corporate transaction.

No Repricing or Exchange Program. No option granted under the 1995 Plan may be repriced, without stockholder approval, including by means of an exchange for cash or another award.

Form of Consideration. The means of payment for shares issued upon exercise of an option is specified in each option agreement and generally may be made by cash, check, other shares of common stock of the Company owned by the optionee, delivery of an exercise notice together with irrevocable instructions to a broker to deliver the exercise price to the Company from sale proceeds, by a combination thereof, or by any consideration and method of payment for the issuance of shares to the extent permitted by applicable laws.

Exercise and Vesting of the Option. Each stock option agreement will specify the term of the option and the date when the option is to become exercisable.

No Dividends. Until a stock certificate is issued following the exercise of a stock option granted under the 1995 Plan, no right to receive dividends will exist with respect to any granted option.

Termination of Employment or Service. If an optionee’s employment or service terminates for any reason (other than death or permanent disability), then all options held by such optionee under the 1995 Plan expire upon the earlier of (i) such period of time as is set forth in his or her option agreement, or (ii) the expiration date of the option. In the absence of a specified time in the option agreement, the option to the extent exercisable, shall remain exercisable for three months following the optionee’s termination of employment or service. The optionee may exercise all or part of his or her option at any time before such expiration to the extent that such option was exercisable at the time of termination of employment or service.

Permanent Disability. If an optionee is unable to continue employment or service with the Company as a result of permanent and total disability (as defined in the Code), then all options, to the extent exercisable, held by such optionee under the 1995 Plan shall expire upon the earlier of (i) 12 months after the date of termination of the optionee’s employment or service, or (ii) the expiration date of the option. The optionee may exercise all or part of his or her option at any time before such expiration to the extent that such option was exercisable at the time of termination of employment or service.

22

Death. If an optionee dies while employed by the Company, then all options, to the extent exercisable, held by such optionee under the 1995 Plan shall expire upon the earlier of (i) 12 months after the date of termination of the optionee’s employment or service, or (ii) the expiration date of the option. The executors or other legal representative of the optionee may exercise all or part of the optionee’s option at any time before such expiration to the extent that such option was exercisable at the time of death.

Termination of Options. Each stock option agreement will specify the term of the option and the date when all or any installment of the option is to become exercisable. However, in no event shall an option granted under the 1995 Plan be exercised more than seven (7) years after the date of grant (ten years in the case of options granted prior to 2012). No options may be exercised by any person after the expiration of its term.

Limitations. If the aggregate fair market value of all shares of common stock subject to an optionee’s incentive stock option that are exercisable for the first time during any calendar year exceeds $100,000, the excess options shall be treated as nonstatutory options.

Other Provisions. The stock option agreement may not contain any term, provision or condition that is inconsistent with the 1995 Plan, as may be determined by our Board of Directors or the Compensation Committee.

Terms and Conditions of SARs

Exercise Price. Our Board of Directors or the Compensation Committee, subject to the provisions of the 1995 Plan, shall have complete discretion to determine the terms and conditions of SARs granted under the 1995 Plan, provided, however, that (i) no SAR may be granted with a per share exercise price less than 100% fair market value on the date of grant, and (ii) no SAR may be repriced, including by means of an exchange for another award, without stockholder approval, including by means of an exchange for another award. However, SARs may be granted with a per share less than 100% fair market value on the date of grant pursuant to a merger or other corporate transaction.

No Repricing or Exchange Program. No SAR granted under the 1995 Plan may be repriced, without stockholder approval, including by means of an exchange for cash or another award.

Dividends. No dividends are payable prior to the vesting of a SAR or any other awards granted under the 1995 Plan.

Payment of Stock Appreciation Right Amount. Upon exercise of a SAR, the holder of the SAR shall be entitled to receive payment from the Company in an amount determined by multiplying (i) the amount by which the fair market value of a share on the date of exercise exceeds the exercise price multiplied by (ii) the number of shares with respect to which the SAR is exercised.

Payment upon Exercise of Stock Appreciation Right. At the discretion of the Compensation Committee, and as specified in the agreement evidencing the SAR, payment to the holder of a SAR may be in cash, shares of our common stock or a combination thereof. In the event that payment to the holder of a SAR is settled in cash, the shares available for issuance under the 1995 Plan shall not be diminished as a result of the settlement.

Stock Appreciation Right Agreement. Each SAR grant shall be evidenced by an agreement that specifies the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Compensation Committee, in its sole discretion, shall determine.

Expiration of SARs. SARs granted under the 1995 Plan expire as determined by the Compensation Committee, but in no event later than seven (7) years from the date of grant (ten years in the case of options granted prior to 2012). No SAR may be exercised by any person after its expiration.

Termination of Employment or Service. If a participant’s employment or service terminates for any reason (other than death or permanent disability), then all SARs held by such participant under the 1995 Plan expire upon the earlier of (i) such period of time as is set forth in his or her SAR agreement, or (ii) the expiration date of the SAR. In the absence of a specified time in the SAR agreement, the SAR, to the extent exercisable, shall remain exercisable for three months following the participant’s termination of employment or service. The participant may exercise all or part of his or her SARs at any time before such expiration to the extent that such option was exercisable at the time of termination of employment or service.

Permanent Disability. If a participant is unable to continue employment or service with the Company as a result of permanent and total disability (as defined in the Code), then all SARs, to the extent exercisable, held by such participant under the 1995 Plan shall expire upon the earlier of (i) 12 months after the date of termination of the participant’s employment or service, or

23

(ii) the expiration date of the SAR. The participant may exercise all or part of his or her SARs at any time before such expiration to the extent that such option was exercisable at the time of termination of employment or service.

Death. If a participant dies while employed by the Company, then all SARs to the extent exercisable held by such participant under the 1995 Plan shall expire upon the earlier of (i) 12 months after the date of termination of the participant’s employment or service, or (ii) the expiration date of the SARs. The executors or other legal representative of the optionee may exercise all or part of the participant’s SARs at any time before such expiration to the extent that such option was exercisable at the time of death.

Terms and Conditions of RSUs

Grant of RSUs. The Compensation Committee, subject to the provisions of the 1995 Plan, shall have complete discretion to determine the terms and conditions of RSUs granted under the 1995 Plan. Each RSU granted on or after June 5, 2019 will count against the share reserve under the 1995 Plan as one share for every RSU granted. Our Board of Directors or the Compensation Committee shall have complete discretion to determine (i) the number of shares subject to RSUs granted to any participant, and (ii) the conditions that must be satisfied (typically based principally or solely on continued provision of services, but may include a performance-based component) for the grant or vesting of RSUs. Until the shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the underlying shares.

RSU Agreement. Each RSU shall be evidenced by an agreement that shall specify such terms and conditions as our Board of Directors or the Compensation Committee shall determine; provided; however, that if the RSU grant has a purchase price, such purchase price must be paid no more than 10 years following the date of grant.

Terms and Conditions of Performance Shares and Units

Grant of Performance Shares. Our Board of Directors or the Compensation Committee, subject to the provisions of the 1995 Plan, shall have complete discretion to determine the terms and conditions of Performance Shares and Performance Units granted under the 1995 Plan. The Compensation Committee shall have complete discretion to determine (i) the number of shares of our common stock subject to a Performance Share award granted to any participant, and (ii) the conditions that must be satisfied (typically based principally or solely on achievement of performance milestones, but may include a service-based component) for the grant or vesting of Performance Shares. No participant shall receive Performance Units having an initial value greater than $1,000,000, except that such participant may receive Performance Units in a fiscal year of the Company in which his or her service as a participant first commences with an initial value no greater than $2,000,000.

Performance Share Award Agreement. Each Performance Share grant shall be evidenced by an agreement that shall specify such other terms and conditions as our Board of Directors or the Compensation Committee, in its sole discretion, shall determine.

Grant of Performance Units. Performance Units are similar to Performance Shares, except that they shall be settled in cash in an amount equivalent to the fair market value of the underlying shares of common stock, determined as of the vesting date. The shares available for issuance under the 1995 Plan shall not be diminished as a result of the settlement of a Performance Unit.

Performance Unit Award Agreement. Each Performance Unit grant shall be evidenced by an agreement that shall specify such terms and conditions as our Board of Directors or the Compensation Committee shall determine. However, no participant shall be granted a Performance Unit award covering more than one million dollars in any of the Company’s fiscal years, except that a newly hired participant may receive a Performance Unit award covering up to two million dollars.

Terms and Conditions of Deferred Stock Units

Grant of Deferred Stock Units. Deferred Stock Units shall consist of an RSU, Performance Share or Performance Unit Award that the Compensation Committee permits to be paid out in installments or on a deferred basis, in accordance with rules and procedures established by our Board of Directors or the Compensation Committee. Deferred Stock Units are subject to the individual annual limits that apply to each type of awards and the annual limits applicable to underlying awards.

Non-Transferability of Awards

Unless determined otherwise by the Compensation Committee, an award granted under the 1995 Plan may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or

24

distribution and may be exercised, during the lifetime of the recipient, only by the recipient. If the Compensation Committee makes an award granted under the 1995 Plan transferable, such award shall contain such additional terms and conditions as the Compensation Committee deems appropriate. In no event may an award be transferred to any third party for value, unless separately approved by our stockholders in advance.

Adjustment Upon Changes in Capitalization; Corporate Transactions

Subject to any required action by the stockholders of the Company, in the event that the stock of the Company is changed by reason of any stock split, reverse stock split, stock dividend, recapitalization or other change in the capital structure of the Company, appropriate proportional adjustments shall be made in the number and class of shares of stock subject to the 1995 Plan, the individual fiscal year limits applicable to RSUs, Performance Share awards, SARS and options, the number and class of shares of stock subject to any award outstanding under the 1995 Plan, and the exercise price of any such outstanding option, RSU or other award. Any such adjustment shall be made upon approval of the Compensation Committee, whose determination shall be conclusive. In the event that we are acquired in any merger of the Company with or into another corporation or the sale of substantially all of the assets, each outstanding award granted under the 1995 Plan shall be assumed or an equivalent right substituted by a successor corporation. If such awards granted under the 1995 Plan are not assumed, they become fully vested prior to the closing of such merger or sale of assets.

Amendment, Suspensions and Termination of the 1995 Plan

The Board of Directors may amend, suspend or terminate the 1995 Plan at any time; provided, however, that stockholder approval is required for any amendment to the extent necessary to comply with Rule 16b-3 promulgated under the Securities Exchange Act of 1934 (“Rule 16b-3”) or Section 422 of the Code, or any similar rule or statute.

Federal Tax Information

Options. Options granted under the 1995 Plan may be either “incentive stock options,” as defined in Section 422 of the Code, or nonstatutory options.

An optionee who is granted an incentive stock option will not recognize taxable income either at the time the option is granted or upon its exercise, although the exercise may subject the optionee to alternative minimum tax. Upon the sale or exchange of the shares more than two years after grant of an incentive stock option and one year after exercising the option, any gain or loss will be treated as long-term capital gain or loss. If these holding periods are not satisfied, the optionee will recognize ordinary income at the time of sale or exchange equal to the difference between the exercise price and the lower of (i) the fair market value of the shares at the date of the option exercise, or (ii) the sale price of the shares. A different rule for measuring ordinary income upon such a premature disposition may apply if the optionee is also an officer or director of the Company. Any gain or loss recognized on such a premature disposition of the shares in excess of the amount treated as ordinary income will be characterized as long-term or short-term capital gain or loss, depending on the holding period.

All options that do not qualify as incentive stock options are referred to as nonstatutory options. An optionee will not recognize any taxable income at the time the optionee is granted a nonstatutory option. However, upon the exercise of a nonstatutory option, the optionee will recognize taxable income generally measured as the excess of the then fair market value of the shares purchased over the purchase price. Any taxable income recognized in connection with the exercise of a nonstatutory option by an optionee who is also an employee of the Company will be subject to tax withholding by the Company. Upon resale of such shares by the optionee, any difference between the sale price and the optionee’s purchase price, to the extent not recognized as taxable income as described above, will be treated as long-term or short-term capital gain or loss, depending on the holding period.

Stock Appreciation Rights. No taxable income is reportable when a stock appreciation right is granted to a participant. Upon exercise, the participant will recognize ordinary income in an amount equal to the amount of cash received and the fair market value of any shares of common stock received. Any additional gain or loss recognized upon any later disposition of the shares of common stock would be capital gain or loss.

RSU, Performance Units and Performance Shares. A participant will not have taxable income upon grant of RSU, Performance Units or Performance Shares. Instead, he or she will recognize ordinary income at the time of vesting equal to the fair market value (on the vesting date) of the vested shares or cash received, minus any amount paid for the shares of vested common stock.

25

Tax Effect for the Company. The Company generally will be entitled to a tax deduction in connection with an award under the 1995 Plan in an amount equal to the ordinary income realized by a participant at the time the participant recognizes such income (for example, the exercise of a nonqualified stock option). Special rules limit the deductibility of compensation paid to our CEO and certain other current and former officers of the Company that qualify as “covered employees” within the meaning of Section 162(m) of the Code (the “Covered Employees”). Under Section 162(m) of the Code, the annual compensation paid to any of these Covered Employees will be deductible only to the extent that it does not exceed $1,000,000. The proposed amendment to the 1995 Plan will eliminate the list of performance goals from which the Compensation Committee had the ability to apply to grants of awards intended to satisfy the requirements of the “performance-based” compensation exception. Prospectively, our Compensation Committee will have discretion as to the criteria upon which to base performance awards under the 1995 Plan may be granted. However, the proposed amendment to the 1995 Plan will not remove or amend any annual award limits currently present in the 1995 Plan.

The foregoing is only a summary of the effect of federal income taxation upon the participant and the Company, does not purport to be complete, and does not discuss the tax consequences of the participant’s death or the income tax laws of any municipality, state or foreign country in which a participant may reside.

Grants to NEOs

The Company is unable to predict the amount of benefits that will be received by, or allocated to, any particular participant under the 1995 Plan. The table that follows shows the RSUs granted to the Company’s NEOs under the 1995 Plan during 2018.

PROPOSAL FIVE

APPROVAL OF AMENDMENT TO HARMONIC’S 2002 DIRECTOR STOCK PLAN

The Company’s stockholders are being asked to approve an amendment to the Company’s 2002 Director Stock Plan (the “2002 Plan”) to (i) prospectively reduce the amount of shares of Common Stock debited from the 2002 Plan with respect to restricted stock units (“RSUs”) to one share for every share subject to an RSU and (ii) institute an annual limit of $600,000 with respect to cash compensation and equity awards made to any non-employee director, including awards made under the 2002 Plan.

Under this proposal, we are not seeking stockholder approval to add new shares to the 2002 Plan share reserve, but requesting approval for changes in how we use the share reserve previously approved by the Company’s stockholders for making grants to the Company’s non-employee directors under the 2002 Plan. If this proposal is approved, we continue to expect the 420,662 shares of Common Stock available for grant under the 2002 Plan, as of April 16, 2019, to be sufficient to make grants for the next two years.

The 2002 Plan is the only equity plan of the Company available for grant of equity awards to the Company's non-employee directors. As of April 16, 2019, options to purchase an aggregate of 60,000 shares of the Company’s common stock were outstanding under the 2002 Plan, with a weighted average exercise price of $5.91 per share and a weighted average term of 1.6 years remaining. In addition, a total of 208,508 RSUs issued under the 2002 Plan had not yet vested. As of April 16, 2019, 420,662 shares were available for future grant under the 2002 Plan.

Proposed Amendments

The 2002 Plan currently permits us to grant a broad range of equity awards to directors of the Company. We established the 2002 Plan in order to assist the Company in attracting and retaining strong board members for the successful conduct and growth of the Company’s business. The Company believes that the 2002 Plan is an essential tool to link the long-term interests of stockholders and directors and is critical to the Company’s ability to attract and retain directors.

In April 2019, our Board of Directors approved amending the 2002 Plan, subject to stockholder approval at the Annual Meeting. The proposed amendment would, with respect to RSUs granted under the 2002 Plan on or after June 5, 2019, reduce the number of shares debited against the 2002 Plan share reserve to 1 share for every RSU and conversely return 1 share to the 2002 Plan reserve for any RSU to the extent forfeited. Any RSU awards that previously debited 1.5 shares against the 2002 Plan share reserve for every RSU will continue to return 1.5 shares to the 2002 Plan reserve for each forfeited RSU. This change is consistent with the changes requested under proposal four with respect to the 1995 Plan.

The proposed amendment would also create a limit of $600,000 that may be paid, issued or granted to any non-employee director in any fiscal year of the Company pursuant to cash compensation and equity awards (including awards issued under the 2002 Plan). For purposes of calculating this limit, the value of equity awards will be based on grant date fair value in accordance with generally accepted accounting principles. Any compensation paid or granted to an individual with respect to his or her services as an employee or consultant will not count for purposes of the annual limit.

The Company’s Board consulted with Compensia prior to approving this amendment, and based on input received from Compensia, believes that the amendments reflected in this proposal are consistent with current best compensation governance practices.

Approval of this proposal requires the affirmative vote of the holders of a majority of the shares of Common Stock that are present in person or by proxy and entitled to vote at our 2019 Annual Meeting.

Our Company’s non-employee directors have an interest in this proposal as they may receive stock options or RSUs under the terms of the 2002 Plan.

SUMMARY OF THE 2002 PLAN

The following is a summary of the principal features of the 2002 Plan, and its operation. This summary is qualified in its entirety by reference to the 2002 Plan. A copy of the 2002 Plan is provided as Appendix B to this proxy statement.

Purposes

The purposes of the 2002 Plan are to attract the best available persons for service as non-employee directors of our Company and to encourage their continued service on our Board of Directors.

27

Term of Plan

The 2002 Plan is set to expire on March 1, 2025.

Eligibility

Only non-employee directors are eligible to receive awards under the 2002 Plan. Currently, our Board of Directors consists of eight directors, of whom seven are non-employee directors. Mr. Harshman, our current President and Chief Executive Officer, is not eligible to receive awards under the 2002 Plan.

Shares Subject to the Plan

Currently, the maximum aggregate number of shares which may be granted, either as stock options or RSUs, and sold under the 2002 Plan is 3,150,000 shares. As of April 16, 2019 420,662 shares of Common Stock remain available for grant under the 2002 Plan. The shares may be authorized, but unissued, or reacquired shares of Common Stock.

Share Counting Provisions

Currently, each award of RSUs counts against the 2002 Plan share reserve as 1.5 shares for every RSU granted. Conversely, the forfeiture of any unvested RSUs results in a credit to the 2002 Plan reserve of 1.5 shares for every RSU forfeited. If this proposal is approved, each award of RSUs granted on or after June 5, 2019 will count against the 2002 Plan share reserve as 1 share for every RSU granted. Conversely, the forfeiture of any unvested RSUs granted on or after June 5, 2019 will result in a credit to the 2002 Plan share reserve of 1 share for every unit forfeited. The forfeiture of any unvested RSUs granted prior to June 5, 2019 will continue to credit 1.5 shares to the 2002 Plan share reserve for each RSU forfeited. Each option award will continue to count against the 2002 Plan reserve 1.0 share for every share subject to the option, and the forfeiture of unvested shares subject to an option will result in a credit to the 2002 Plan reserve of 1.0 share for every share forfeited.

No Repricing or Exchange Program.

No option granted under the 2002 Plan may be repriced without stockholder approval, including by means of an exchange for another award.

Administration

The 2002 Plan provides for grants of awards to be made in three ways:

1. Initial Grants. Each new non-employee director who joins the Board (excluding a former employee director who ceases to be an employee, but who remains a director) is entitled to receive stock options or RSUs, or a mix thereof, on the date that the individual is first appointed or elected to the Board, as determined by the Board in its sole discretion. An employee director who ceases to be an employee director, but who remains a director, will not receive this initial award.

2. Ongoing Grants. Each non-employee director who has served on the Board for at least six months, as of the date of grant, will receive an annual grant of stock options or RSUs, or a mix thereof, as determined by the Board in its sole discretion.

3. Discretionary Grants. The Board may make discretionary grants of stock options or RSUs (or a combination of options and RSUs) to any non-employee director.

Terms of Awards

Each award of RSUs or stock options is evidenced by a written agreement between us and the applicable non-employee director in such form, and subject to such terms and conditions, including vesting provisions, as the Board shall approve. Options are subject to the following terms and conditions:

1. Option Term. The term of options may not exceed seven years.

2. Exercise Price. The exercise price per share may not be less than 100% of the fair market value per share of the Common Stock on the grant date.

3. Termination of Continuous Status as Director. If a non-employee director’s status as a director terminates, all of their vested options expire upon the earlier of the options’ original maximum term or three years following such termination of service.

28

4. Nontransferability of Options. Options granted under the 2002 Plan are not transferable other than by will or the laws of descent and distribution, and may be exercised, during the non-employee director’s lifetime, only by the non-employee director.

Annual Limit

If this proposal is approved, the 2002 Plan would also include a limit of $600,000 that may be paid, issued or granted to any non-employee director in any fiscal year of the Company pursuant to cash compensation and equity awards (including awards issued under the 2002 Plan). For purposes of calculating this limit, the value of equity awards will be based on grant date fair value in accordance with generally accepted accounting principles. Any compensation paid or granted to an individual with respect to his or her services as an employee or consultant will not count for purposes of the annual limit.

Adjustments upon Changes in Capitalization, Dissolution, Merger or Change-in-Control

In the event of a stock split, reverse stock split, stock dividend, or any combination or reclassification of the Common Stock, or other similar change in our capital structure effected without receipt of consideration by us, proportionate adjustments will be made to the number of shares covered by each outstanding award, the number of shares authorized for issuance that remain available to be granted under the 2002 Plan, and the exercise price of each outstanding stock option. For this purpose, any conversion of convertible securities is not considered effected without our receiving consideration.

In the event of a proposed dissolution or liquidation of the Company, any unexercised options and unvested RSUs will terminate prior to the consummation of such proposed action.

If a successor corporation assumes or substitutes the options under the 2002 Plan as a result of a merger of the Company with or into another corporation or a change-in-control of the Company, as defined in the 2002 Plan (a “Change-in-Control”), such options will remain exercisable in accordance with the 2002 Plan. In the event of a Change-in-Control, all options and RSUs held by non-employee directors immediately become fully vested.

Amendment and Termination of the 2002 Plan

The Board may at any time amend, alter, suspend, or discontinue the 2002 Plan to the extent such actions do not impair the rights of any recipient of awards under the 2002 Plan, unless he or she consents. To the extent necessary and desirable to comply with any applicable law, regulation or stock exchange rule, the Company must obtain stockholder approval of any 2002 Plan amendment in the manner or to the degree required.

Certain Federal Income Tax Information

Stock Options. Options granted under the 2002 Plan are nonstatutory options and do not qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). An optionee will not recognize any taxable income at the time of grant of a nonstatutory option. However, upon its exercise, the optionee will recognize ordinary income for tax purposes measured by the excess of the fair market value of the shares on the date of exercise over the exercise price. The Company will be entitled to a tax deduction in the amount and at the time that the optionee recognizes ordinary income with respect to shares acquired upon exercise of an option.

Restricted Stock Units. A participant will not have taxable income upon grant of an RSU. Instead, he or she will recognize ordinary income at the time of settlement equal to the fair market value of the delivered shares. The Company will be entitled to a tax deduction in the amount and at the time that the non-employee director recognizes ordinary income with respect to shares acquired upon settlement of an RSU.

The foregoing summary of the federal income tax consequences of the 2002 Plan transactions is based on U.S. federal income tax laws in effect on the date of this Proxy Statement. This summary is not intended to be complete and does not describe foreign, state, or local tax consequences.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING “FOR” THE APPROVAL OF THE PROPOSED AMENDMENT TO THE 2002 DIRECTOR STOCK PLAN.

PROPOSAL SIX

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has appointed Armanino LLP (“Armanino”), an independent registered public accounting firm, to audit the financial statements of the Company for the year ending December 31, 2019. Armanino has served as the Company’s independent registered public accounting firm since March 2018. Prior to Armanino’s appointment, PricewaterhouseCoopers LLP (“PwC”) served as the Company’s independent registered public accounting firm and PwC served as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2017.

Stockholder approval is not required for the appointment of Armanino, as the Audit Committee has the responsibility for selecting an independent registered public accounting firm. However, the Board is submitting the selection of Armanino to the stockholders for ratification as a matter of good corporate practice. In the event of a negative vote on the ratification of Armanino, the Audit Committee may reconsider its selection. Representatives of Armanino are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they so desire. The representatives also are expected to be available to respond to appropriate questions from stockholders. Representatives of PwC are not expected to be present at the Annual Meeting or to be available to respond to appropriate questions from stockholders, and will not have the opportunity to make a statement if they so desire.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING “FOR” THE RATIFICATION OF THE APPOINTMENT OF ARMANINO LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2019.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES

Aggregate fees for professional services rendered for the Company by (i) Armanino for the year ended December 31, 2018 and (ii) the Company’s previous independent registered public accounting firm, PwC, for the year ended December 31, 2017 were as follows:

	2018	2017
	(In thousands)
Audit Fees	$1,198	$2,265
Audit-Related Fees	—	—
Tax Fees	4	503
All Other Fees	20	29
Total	$1,222	$2,797

Audit Fees

These amounts represent fees billed for professional services rendered for the audit of our consolidated financial statements and review of interim statements included in quarterly reports and services that are normally provided by Armanino (and by PwC in 2017) in connection with statutory and regulatory filings or engagements.

Audit-Related Fees

These amounts represent fees billed for assurance and related services by Armanino (and by PwC in 2017) that are reasonably related to the performance of the audit or review of the Company’s financial statements and are not reported under Audit Fees.

Tax Fees

For 2017, this amount represents fees billed by PwC for professional services for tax compliance, tax advice, tax planning and preparation of foreign employee tax returns. These services include assistance regarding federal, state and international tax compliance, customs and duties and international tax planning. For 2018, this amount represents fees billed by an affiliate of Armanino for international tax compliance.

30

All Other Fees

For 2017, these amounts represent fees billed by PwC for subscription to a software research tool developed by PwC and include fees for reviewing reports provided by our French subsidiary to a French financial regulatory authority and reviewing the compliance of our ERP software implementation in France. For 2018, these amounts represent fees billed by an affiliate of Armanino for reviewing reports provided by our subsidiary in Switzerland to a Swiss financial regulatory authority.

Consistent with its charter, the Audit Committee pre-approves all audit and non-audit services from our independent registered public accounting firm and did so in 2018. Pre-approval authority may be delegated by the Audit Committee to the Chair of the Audit Committee.

The Audit Committee considered whether the services provided by Armanino in 2018, and by PwC in 2017, were compatible with maintaining the independence of Armanino and PwC, respectively, and concluded that the independence of each of Armanino and PwC was maintained and was not compromised by the non-audit services provided.

Dismissal of PwC and Hiring of Armanino.

On March 26, 2018, the Audit Committee dismissed PwC as the Company’s independent registered public accounting firm and hired Armanino as the Company’s independent registered public accounting firm.

The audit report of PwC on the Company’s consolidated financial statements as of and for the year ended December 31, 2017 did not contain an adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal year ended December 31, 2017 and the subsequent interim period through March 26, 2018, (i) there were no disagreements with PwC on any matters of accounting principles or practices, financial statement disclosures or auditing scope and procedures, which disagreements, if not resolved to the satisfaction of PwC, would have caused PwC to make reference thereto in its reports on the financial statements for such years, and (ii) there were no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended (“Regulation S-K”)).

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

In accordance with a written charter adopted by Harmonic’s Board of Directors and posted on the Company’s website at www.harmonicinc.com, the Audit Committee of the Board of Directors serves as the representative of the Board of Directors for general oversight of the quality and integrity of the Company’s financial accounting and reporting process, system of internal control over financial reporting, audit process, and process for monitoring compliance with related laws and regulations. The Audit Committee engages the Company’s independent registered public accounting firm and approves the scope of both audit and non-audit services. Harmonic’s management has primary responsibility for preparing financial statements and the financial reporting process.

Armanino LLP, Harmonic’s independent registered public accounting firm for the year ended December 31, 2018, was responsible for performing an independent audit of the Company’s consolidated financial statements and internal control over financial reporting in accordance with the standards set by the Public Company Accounting Oversight Board (“PCAOB”) and to issue reports thereon.

The Audit Committee has:

1. Reviewed and discussed the audited consolidated financial statements and certifications thereof with Company management and Armanino LLP and management has represented to the Audit Committee that Harmonic’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States;

2. Discussed with Armanino LLP the matters required to be discussed by the PCAOB Auditing Standard No. 1301 (Communications with Audit Committees), including discussion of the quality and acceptability of Harmonic’s financial reporting process and controls; and

3. Received the written disclosures and letter from Armanino LLP required by applicable requirements of the PCAOB regarding Armanino LLP’s communications with the Audit Committee concerning independence, discussed with Armanino LLP its independence, and considered whether the provision of the non-audit services described above was compatible with maintaining their independence.

The Audit Committee meets regularly with the Company’s independent registered public accounting firm, with and without management present, to discuss the results of their examinations, the evaluations of the Company’s internal control over financial reporting, and the overall quality of the Company’s adherence to applicable accounting principles and practices.

31

In performing all of these functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the work and assurances of Harmonic’s management, which has primary responsibility for preparing financial statements and the financial reporting process, and the independent registered public accounting firm, which, in their report, expresses an opinion on the conformity of Harmonic’s annual consolidated financial statements to accounting principles generally accepted in the United States and of the Company’s internal control over financial reporting in accordance with the standards set by the PCAOB. In reliance on the reviews and discussions referred to in this report, and in light of its role and responsibilities, the Audit Committee recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements of Harmonic for the three years ended December 31, 2018 be included for filing with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Philosophy and Programs

The Company’s executive compensation programs are designed to attract, motivate and retain executives who will contribute significantly to the long-term success of the Company and the enhancement of stockholder value. Consistent with this philosophy, the following goals provide a framework for our executive compensation program:

• provide a competitive total compensation package to attract, retain and motivate executives who must operate in a demanding and rapidly changing business environment;

• relate total compensation for each executive, consisting of base salary, annual cash bonus and equity awards, to overall Company performance and, in the case of base salary and equity awards, to individual performance;

• tie incentive bonus compensation to the Company’s achievement of objective performance parameters;

• reflect competitive market requirements and strategic business needs in determining the appropriate mix of cash and non-cash compensation and short-term (base salary and annual cash bonus) and long-term compensation (equity awards);

• put at risk a significant portion of each executive’s total target compensation, with the intent to reward superior performance by the Company; and

• align the interests of our executives with those of our stockholders.

At our 2018 annual meeting of stockholders, we held a stockholder advisory vote on the compensation of our NEOs, commonly referred to as a “say-on-pay vote.” Our stockholders approved the compensation of our NEOs, with approximately 98% of stockholder votes cast voting in favor of the say-on-pay proposal. As we evaluated our compensation practices and talent needs throughout 2018, we were mindful of the support our stockholders expressed for our philosophy of linking compensation to our financial goals and in support of enhancing stockholder value. As a result, the Compensation Committee decided to retain our general approach with respect to our executive compensation programs, with an emphasis on delivering long-term and short-term incentive compensation that rewards our executives commensurate with the value they deliver to our stockholders.

Role of the Compensation Committee

The Compensation Committee is responsible for approval of the Company’s executive compensation policies, compensation paid to executive officers, and administration of the Company’s equity ownership plans. The Compensation Committee currently consists of Messrs. Kvamme, Gallagher and Krall and Ms. Reaugh, none of whom is an employee of the Company, and each of whom is independent under applicable NASDAQ listing standards and Section 16 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The charter of the Compensation Committee was adopted by the Board of Directors, and is posted on Harmonic’s website at www.harmonicinc.com.

Role of the Compensation Consultant

The Compensation Committee has retained the services of Compensia, Inc. (“Compensia”), an independent compensation consulting firm, to assist the Compensation Committee in the evaluation of appropriate cash and equity compensation for executive management and the Board. Compensia provides no other services to the Company. Compensia makes recommendations to the Compensation Committee on the design and implementation of compensation plans, assists in determining the appropriate number of shares to be used for equity awards granted under the Company’s equity plans, reviews market and other data and recommendations provided by management, and also reviews specific compensation proposals for each of the Company’s NEOs. Compensia attends all or part of certain Compensation Committee meetings, as requested by the Compensation Committee.

In 2018, the Compensation Committee considered and assessed all relevant factors, including those set forth in Rule 10C-1(b)(4)(i) through (vi) under the Exchange Act, that could give rise to a potential conflict of interest with respect to Compensia’s work. Based on this review, we are not aware of any conflict of interest that has been raised by the work performed by Compensia.

Role of Management

Our CEO, assisted by our General Counsel and Senior Vice President, Human Resources, works with the Compensation Committee to establish meeting agendas. The CEO makes recommendations to the Compensation

34

Committee with respect to the compensation of other members of executive management and the design and implementation of incentive compensation programs for NEOs. For 2018 executive compensation, these recommendations were developed with the assistance of Compensia. The Compensation Committee considers the recommendations of management, but is not bound by such recommendations. The CEO does not make recommendations to the Compensation Committee with respect to his own compensation and no member of management is present at any portion of Compensation Committee meetings when his or her compensation is deliberated or decisions are made.

Management of Risk Arising from Incentive Compensation Policies

The Compensation Committee has considered whether the Company’s overall compensation program for employees creates incentives for employees to take excessive or unreasonable risks that could materially harm the Company. The Committee believes that our incentive plans are typical for our industry and market competitive, and that risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on the Company. Several features of our compensation policies for management employees appropriately mitigate such risks, including a mix of long-term and short-term compensation incentives that we believe are properly weighted, the uniformity of compensation policies across the Company, caps on payments from the plans and the use of our business plan, which the Compensation Committee believes sets an appropriate level of risk for the Company, as a baseline for our incentive bonus plan targets. We also believe the Company’s internal legal and financial controls, as well as the Clawback Policy described on page 40 of this Proxy Statement, appropriately mitigate the probability and potential impact of an individual employee committing the Company to inappropriate transactions in exchange for short-term compensation benefits.

Elements of Compensation

In order to achieve the above goals, our total compensation packages include base salary and annual bonus paid in cash, as well as long-term equity compensation, all as described in greater detail below. We also make available benefit plans to our executive officers which are generally provided to all regular full-time employees of Harmonic. We believe that appropriately balancing the total compensation package and ensuring a significant portion of the package is incentive-based is necessary in order to provide market-competitive compensation. We focus on ensuring that the balance of the various components of our compensation program is optimized to motivate executives to improve our results on a cost-effective basis. The factors which are used to determine individual compensation packages are generally similar for each NEO, including our CEO.

In order to assess our compensation competitiveness against peer companies in 2018, the Compensation Committee, with input from Compensia, approved a compensation peer group, which included 17 companies. These peer companies were selected primarily from the telecommunications, video services technology and software industries based principally on revenue and market capitalization data that placed Harmonic approximately in the middle of the range, as well as on such companies' proximity to Silicon Valley, which is the location of the Company’s headquarters.

Compared to the peer group used prior to its approval for 2018, one former peer company - Nimble Storage - was removed from the peer group due to its acquisition by a third party in 2017. Another former peer company - Sonus Networks - merged with a third party in 2017 and was replaced in the peer group with the combined and renamed company, Ribbon Communications. Aerohive Networks, Coherent, Electronics for Imaging, Infinera, Quantum and SeaChange International were removed from the peer group because these companies no longer fit the revenue and/or market capitalization parameters established by the Compensation Committee with the assistance of Compensia. The final list of peer group companies used for setting 2018 executive compensation is set forth below.

Data prepared by Compensia for the compensation peer group was used as a reference point by the Compensation Committee for making decisions regarding 2018 cash and equity compensation and for the design and implementation of compensation packages and for specific proposals related to the individual elements and total compensation packages for other NEOs, as well as for other employees.

35

The approved peer group for 2018 consisted of the following companies:

A10 Networks	Extreme Networks
ADTRAN	Internap
Avid Technology	NeoPhotonics
Brightcove Inc.	QAD
CalAMP	Quantenna Communications
Calix	Ribbon Communications
Casa Systems	TESSCO Technologies
DASAN Zhone Solution	Universal Electronics
Digi International

Base Salary

Base salaries for NEOs, including that of the CEO, are set according to the responsibilities of the position, the specific skills and experience of the individual and the competitive market for executive talent. The Compensation Committee reviews salaries annually and adjusts them as appropriate to reflect changes in market conditions, individual performance and responsibilities, and the Company’s financial position. The aggregate value of our total cash compensation (base salary and targeted bonus) for NEOs is generally targeted at approximately between the 50 ^th and 60 ^th percentile of executive compensation of the compensation peer group, depending on position, with the intent that superior performance under incentive bonus plans would enable the executive to elevate total cash compensation to levels that are above the average of comparable companies.

Following a review of the above factors and the data regarding the compensation peer group in 2018, the Compensation Committee agreed to defer any decisions on increases to base salaries for NEOs until 2019.

Base salaries for all of the NEOs for 2016, 2017 and 2018 are disclosed in the Summary Compensation Table on page 42 of this Proxy Statement.

Incentive Bonus Plans

The Company’s annual incentive bonus plans in which NEOs participate reflect the Compensation Committee’s belief that a meaningful component of executive compensation should be contingent on the Company achieving performance targets, thereby introducing a significant element of “pay for performance” and appropriate incentives to produce superior results.

The 2018 annual base salary and bonus target opportunity for each of the NEOs is set forth below.

		Annual Base Salary	Target Bonus as % of Base Salary
Patrick Harshman	$	514,500	125%
Sanjay Kalra		357,000	55%
Nimrod Ben-Natan (1)		326,012	60%
Neven Haltmayer		339,201	57%
Tim Warren (1)		301,726	55%

(1 ) The base salary amounts for Messrs. Ben-Natan and Warren have been converted from Israeli Shekel and Hong Kong Dollar, respectively.

Overview

For 2018, the Compensation Committee agreed to incentivize performance based on half-year targets. In the first quarter of 2018, the Compensation Committee approved a first-half (“H1”) corporate incentive bonus plan (the “H1 Corporate Bonus Plan”) in which (i) 60% of the target bonus for plan participants (including the NEOs, other than Mr. Ben-Natan, who was subject to a different bonus plan as described below) was tied to achievement of the H1 non-GAAP Company gross profit target and (ii) 40% was tied to achievement of the applicable non-GAAP H1 spending target established for a plan participant’s function. In the third quarter of 2018, the Compensation Committee approved a second-half (“H2”) corporate incentive plan (the “H2 Corporate Bonus Plan”) in which (i) 70% of the target bonus was tied to

36

achievement of the H2 non-GAAP Company gross profit target and (ii) 30% was tied to achievement of the applicable non-GAAP H2 spending target established for a plan participant’s function.

With respect to Mr. Ben-Natan, he participated in the Cable Access incentive bonus plans established for H1 and H2 2018 (the “H1 Cable Access Bonus Plan” and “H2 Cable Access Bonus Plan”), which were, for both H1 and H2, based (i) 40% against achievement of non-GAAP Cable Access business segment gross profit targets, (ii) 30% against achievement of non-GAAP Cable Access spending targets, and (iii) 30% against achievement of CableOS design win targets (i.e., bookings from new customers).

The Compensation Committee approved these bonus plans and bonus plan components to focus the NEOs and other incentive plan participants on improved profitability, spending and expense management and growing the Cable Access business. In addition, the 2018 incentive bonus plans had minimum thresholds that had to be met in order for any H1 or H2 payout to be made, as well as maximum payout caps for each component of the incentive bonus plans, as set forth in the tables below.

For 2018, the Compensation Committee approved the following targets and payout thresholds for the H1 and H2 Corporate Bonus Plans and Cable Access Bonus Plans (together, the “Bonus Plans”):

H1 and H2 Corporate Bonus Plan targets(in millions of U.S. dollars)

		H1		H2
Non-GAAP Company gross profit:	$	102.1	$	109.5
Non-GAAP functional spending: (1)		143.9		144.0

(1 ) Amounts shown are total Company spending targets and achievement was measured against the applicable H1 and H2 spending targets for a participant’s function.

H1 and H2 Cable Access Bonus Plan targets(in millions of U.S. dollars, except for design wins)

		H1		H2
Non-GAAP Cable Access gross profit:	$	17.1	$	27.9
Cable Access functional spending:		17.3		18.6
CableOS design wins:		4		8

H1 payout thresholds and payout caps applicable to Bonus Plans

Gross Profit		Functional Spending
Achievement	Payout	Achievement	Payout
< 90%	0%	90%	200%
95%	50%	95%	150%
100%	100%	100%	100%
110%	200%	105%	25%
		>105%	0%

H2 payout thresholds and payout caps applicable to Bonus Plans

Gross Profit		Functional Spending
Achievement	Payout	Achievement	Payout
< 90%	0%	90%	125%
95%	50%	95%	110%
100%	100%	100%	100%
110%	150%	105%	25%
115%	250%	>105%	0%

37

With respect to the payout threshold for CableOS design wins, the full payout would be earned with four (4) qualified design wins in H1 and eight (8) qualified design wins in H2, a prorated payout would be earned if less than the targeted H1 or H2 qualified design wins are achieved, and there would be no cap on payouts for overachievement (which would be at the same prorated rate).

For performance between these achievement levels, payouts for the applicable bonus plan component would be determined by straight-line interpolation. Any payout for overachievement (i.e., > 100%) of an H1 bonus plan component would be deferred until year-end 2018.

Achievement

No payments would be made under any of the components of the Bonus Plans if the threshold H1 or H2 target, as applicable, for any such component was not achieved. The Compensation Committee believed that the targets for the Bonus Plans were challenging but achievable, based on their review of the Company’s operating plan for 2018, their experience with respect to the Company’s historical performance and the business and industry outlook.

With respect to the H1 and H2 Corporate Bonus Plans, the Company (i) overachieved the gross profit targets for H1 and H2 and (ii) overachieved (i.e., came in below) the total spending targets for H1 and H2, with each NEO under the Corporate Bonus Plans overachieving (i.e., coming in below) the spending targets assigned to his function. As a result, payouts for NEOs under the H1 Corporate Bonus Plan were earned at between approximately 108% to 126% of the NEO’s H1 target bonus opportunity under the H1 plan, and payouts under the H2 Corporate Bonus Plan were earned at between approximately 123% to 125% of the NEO’s H2 target bonus opportunity under the H2 plan.

With respect to the H1 and H2 Cable Access Bonus Plans, the Cable Access business segment (i) overachieved the H1 gross profit target and did not achieve the H2 gross profit target, (ii) overachieved (i.e., came in below) the spending targets for H1 and H2 and (iii) overachieved the H1 target number of qualified CableOS design wins and underachieved the H2 design win target number. As a result, Mr. Ben-Natan earned approximately 173% of his target bonus opportunity under the H1 Cable Access Bonus Plan and earned approximately 46% of his target bonus opportunity under the H2 Cable Access Bonus Plan.

Amounts earned by the NEOs, other than Mr. Harshman, under the H1 Bonus Plans were satisfied through the granting of fully-vested performance-based RSUs. In each case, the number of performance-based RSUs granted to each NEO was determined by dividing the dollar value of the earned bonus amount by the share price of the Company’s common stock on a pre-established calculation date that was a few business days prior to the grant date. All amounts earned by Mr. Harshman under the Bonus Plans in H1 and H2 were paid in cash, and all amounts earned under the H2 Bonus Plans by the other NEOs were paid in cash.

In December 2018, the Compensation Committee approved a one-time discretionary bonus payment to Mr. Kalra in the amount of $75,000 to recognize his performance and contributions to the Company.

Equity Compensation Plans

The Compensation Committee believes that equity compensation plans are an essential tool to link the long-term interests of stockholders and employees, especially the CEO and executive management, and serve to motivate employees, and particularly executive management, to make decisions that will, in the long run, deliver the best returns to stockholders, thus rewarding excellent long-term performance. From 2009 to 2017, stock options and RSUs were granted to Company executives, including NEOs, when they joined the Company, and on an annual basis thereafter. Since 2017, the Compensation Committee has granted the Company’s NEOs and other executives a combination of time-based and performance-based RSUs, and has not granted any stock options.

In 2018, in light of a trend among the Company’s peer group as well as similarly situated publicly-listed technology companies favoring full-value awards, the Compensation Committee decided to continue to focus on granting an appropriate combination of time-based vesting and performance-based vesting RSUs to NEOs and executives rather than stock option awards. The Compensation Committee may employ stock option grants in the future, in combination with RSUs and/or performance-based RSUs.

The 2018 timed-based RSUs granted to executives and NEOs vest over 3 years subject to their continued service. Messrs. Harshman and Ben-Natan were also granted performance-based RSUs with vesting based on achievement of a

38

2018 Cable Access business segment revenue target. In February 2019, the Compensation Committee determined 2018 Cable Access business segment revenue metric was achieved, resulting in 100% of the performance-based RSUs granted to Messrs. Harshman and Ben-Natan vesting.

Mr. Harshman was also granted a stock price performance-based RSU (the “SPRSU”) in 2018 that may vest during an 18 month performance period, as follows: (i) if the closing price of the Company’s common stock, as quoted on the NASDAQ Stock Market, equals or exceeds certain stock price thresholds for at least 20 consecutive trading days (the “Minimum Trading Period”), then 50% of the performance-based RSUs will vest on the final day of the Minimum Trading Period and (ii) if the stock price threshold for which the Minimum Trading Period has been satisfied exceeds the other stock price threshold for which the performance-based RSU award has not already vested, then the vesting associated with both stock price thresholds shall occur as of the close of market on the final day of the Minimum Trading Period. Finally, as described above performance-based RSUs were granted to certain NEOs in the third quarter of 2018 to satisfy amounts earned for achieving half-year performance targets under the H1 Bonus Plans.

Upon vesting, shares are immediately issued and there are no additional time- or service-based conditions associated with the performance-based RSUs or SPRSUs, other than the CEO stock ownership guidelines applicable to Mr. Harshman as further described below under “Stock Ownership Guidelines”. The Compensation Committee believes these performance-based RSUs and SPRSUs appropriately incentivizes the NEOs and directly aligns management’s and the stockholders’ interests.

Consistent with past practice, the total equity pool for annual grants to be made to all employees in 2018, including NEOs, was determined principally by reference to industry-specific guidelines published by shareholder advisory firms and, in part, by historic practice. The guidelines generally refer to metrics such as total annual awards as a percentage of shares outstanding and total outstanding awards as a percentage of fully diluted shares. The Compensation Committee, in consultation with the Company’s CEO (except with respect to the CEO’s own compensation), determines the size and material terms of equity awards granted to the NEOs, taking into account the role and responsibility of the NEO, competitive factors including competition for technology executives; peer group data compiled by the Compensation Committee’s compensation consultant, the size and value of long-term equity compensation already held by each executive officer and the vested percentage; the proportion between RSUs, performance-based RSUs and stock options held by each NEO; the total target cash compensation opportunity for each NEO; and individual performance and retention objectives.

Equity Compensation Grant Practice

The Compensation Committee approves all equity grants, except for certain grants made to non-executive employees in the ordinary course of business, for which it has delegated authority to the CEO, within parameters approved in advance by the Compensation Committee, pursuant to an employee equity issuance policy (the “Employee Equity Issuance Policy”). The Compensation Committee reviews all grants made pursuant to the Employee Equity Issuance Policy. Initial hire grants of RSUs are made on the second Friday of each month, and any other grants made by the CEO pursuant to authority granted by the Compensation Committee are made on the Friday of the week of such grant. Stock options, if issued, are granted at 100% of the closing price of our stock on the NASDAQ Stock Market on the date of grant.

Initial hire grants that are for executives reporting to the CEO or grants that are above the CEO’s approved range are approved by the Compensation Committee, with the grant date being the day of approval by the Compensation Committee or a later date selected by the Compensation Committee and, if in the form of a stock option, the exercise price being the closing price of the stock on the NASDAQ Stock Market on the grant date. The initial grants are effective as of the date of grant, with vesting generally beginning on the date of commencement of employment. Annual grants are usually made in the first half of the year, and, in 2018, these grants were made in March and April. This timing enables management and the Compensation Committee to consider performance by both the Company and the individual and balance it against our expectations for the current year.

We do not time the granting of RSUs or stock options with any favorable or unfavorable news released by the Company. The timing of initial grants is driven by the date of hire of our new employees. The Board of Directors and Compensation Committee meeting schedules, for review and approval of annual grants, are usually established several months in advance for the calendar year. Proximity of any awards to an earnings announcement or other market events is coincidental.

Retirement Benefits

39

The Company does not provide pension benefits or deferred compensation plans to any of its U.S. employees, including NEOs, other than a 401(k) deferred compensation plan which is open to all regular, full-time U.S. employees. The Company has a matching contribution policy for the 401(k) plan, of up to $1,000 a year for each participant, for 2018. For employees resident in foreign jurisdictions, the Company makes required contributions to statutory pension and retirement schemes and, in a few countries, offers supplemental pension benefits in accordance with customary market practices.

Change-of-Control Agreements

The Company does not have employment agreements with any of its present NEOs. However, as a historical practice, it has generally provided change of control severance agreements to its NEOs and certain other executives. These agreements are designed to incentivize continuing service to the Company by NEOs in the event that the Company may be in discussions regarding strategic transactions and to provide short-term benefits in the event that a NEO’s position is eliminated or responsibilities or compensation are reduced following a change of control.

Under the terms of the current NEO’s current change of control severance agreements, in the event of termination of the NEO other than for cause (as defined in the relevant change of control severance agreement) within 18 months following a change in control of the Company, the NEO will be entitled to certain payments described below.

Mr. Harshman, the Company’s President and CEO, will receive, subject to the execution of a standard release, (i) a lump-sum payment of twice his annual salary; (ii) an amount equal to the greater of (x) 200% of his then annual target bonus or (y) 200% of the average of the actual bonus paid to him in each of the two prior years; and (iii) a continuation of his health, dental, and life insurance benefits for up to one year after termination of employment. Mr. Harshman’s agreement also provides for out-placement assistance and the full acceleration of unvested stock options and any restricted stock awards held by him in the event of such termination, subject to certain limitations.

Each of the other NEOs will receive, subject to the execution of a standard release, (i) a lump-sum payment of one year’s salary; (ii) an amount equal to the greater of (x) 100% of the NEO’s then annual target bonus or (y) the average of the actual bonus paid to the NEO in each of the two prior years; and (iii) a continuation of the NEO’s health, dental and life insurance benefits for up to one year after termination of employment. These agreements also provide for out-placement assistance and the full acceleration of unvested stock options and any restricted stock awards held by the respective NEO in the event of such termination, subject to certain limitations.

Other Compensation

Other elements of compensation available to the Company's NEOs include life and long-term disability insurance and health benefits. These benefits are available to all regular, full-time U.S. employees of the Company on the same basis, and similar benefits are provided to most employees in other countries. In addition, the Company may provide for relocation expenses to recruit key executives living outside the San Francisco Bay Area. Management periodically reviews the level of benefits provided to all employees and adjusts those levels as appropriate. The value of the benefits received by the Company’s NEOs pursuant to these other elements of compensation in 2016, 2017 and 2018 are included in the “All Other Compensation” column in the Summary Compensation Table on page 42 of this proxy statement.

Stock Ownership Guidelines

The Company has adopted stock ownership guidelines applicable to its CEO, requiring the CEO to hold any shares issued, after withholding of shares for taxes resulting from the exercise of vested stock options granted in 2017 or later or settlement of vested RSUs granted in 2017 or later, for at least 36 months from the date of RSU settlement or stock option exercise, subject to release from these requirements upon his separation from service with the Company.

Financial Restatements and Clawback Policy

The Company has never restated its financial statements. The Compensation Committee has adopted a Clawback Policy pursuant to which we may seek the recovery of incentive compensation, including equity compensation, paid by the Company to our executive officers. The Clawback Policy provides that if (i) the Company restates its financial statements as a result of a material error; (ii) the amount of incentive compensation that was paid or is payable based on achievement of specific financial results paid would have been less if the financial statements had been correct; (iii) no more than two years have elapsed since the original filing date of the financial statements upon which the incentive compensation was determined; and (iv) the Compensation Committee unanimously concludes, in its sole discretion, that fraud or intentional

40

misconduct by any executive officer(s) caused the material error and it would be in the best interests of the Company to seek from such participant(s) recovery of the excess compensation, then the Compensation Committee may, in its sole discretion, seek from such executive officer(s) repayment to the Company of the applicable incentive compensation.

Section 162(m)

We have considered the potential future effects of Section 162(m) of the Code on the compensation paid to our NEOs. Section 162(m) disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1.0 million in any taxable year for each of the CEO and the three other most highly compensated executive officers other than our Chief Financial Officer.

Prior to 2018, Section 162(m) of the Code provided an additional exception that stated that remuneration in excess of $1.0 million to employees that are subject to the Section 162(m) of the Code deduction limits may be fully deductible for tax purposes if it is “performance-based compensation” within the meaning of Section 162(m) of the Code or qualifies for one of the other exemptions from the deductibility limit.

Recent tax reform legislation eliminated the exception for “performance-based” compensation beginning in 2018 and expanded the number of individuals covered by Section 162(m) of the Code, subject to certain exceptions for compensation payable pursuant to a “written binding contract” in effect on November 2, 2017 that has not been subsequently materially modified.  

While the Compensation Committee considers the deductibility of compensation as a factor in making compensation decisions, the Compensation Committee retains the flexibility to provide compensation that is consistent with our goals for our executive compensation program even if such compensation is not fully tax deductible.  The Compensation Committee may make decisions that result in compensation expense that is not fully deductible under Section 162(m) of the Code.

(1	)	The amounts in this column represent the fair value of the RSU award, performance-based RSU award or option award, as applicable, on the grant date, computed in accordance with applicable accounting standards, and do not reflect actual amounts paid to or received by any officer. The grant date fair market value of the service-based RSU awards granted in 2018, 2017 and 2016 is equal to the number of RSUs granted multiplied by the closing price of our stock on the NASDAQ Stock Marketon the date of grant. The grant date fair market value of the option awards granted in 2016 is calculated using the Black-Scholes option pricing model as specified in Note 12, “Employee Benefit Plans and Stock-Based Compensation - Valuation Assumption” to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.
		The amounts in this column also include stock price performance-based RSUs (the “SPRSUs”) granted to Mr. Harshman in 2018 and SPRSUs granted to Messrs. Harshman, Kalra, Ben-Natan and Haltmayer in 2017. The grant date fair market value of the SPRSUs was determined using a Monte- Carlo methodology, as specified in Note 12, “Employee Benefit Plans and Stock-Based Compensation - Performance- and Market-based awards” to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Assuming the highest level of performance is achieved under the performance measures for the SPRSUs, the maximum possible value of the SPRSUs using the closing price of our common stock on the NASDAQ Stock Market on the date of grant is presented below:

	Maximum Value of SPRSUs (as of Grant Date)
Name	2018	2017
Patrick J. Harshman	$146,000	$487,200
Sanjay Kalra	—	140,000
Nimrod Ben-Natan	—	208,800
Neven Haltmayer	—	147,900

Harshman and Ben-Natan with vesting based on achievement of a Cable Access business-related revenue target for 2018. The grant date fair market value of these PRSUs was $219,000 for Mr. Harshman and $154,000 for Mr. Ben-Natan. For 2018, the amounts in this column also include fully-vested performance-based RSUs that were granted to certain NEOs in the third quarter of 2018 to satisfy amounts earned for achieving half-year performance targets under the Company’s 2018 incentive bonus plans. The grant date fair market value of these RSUs was $88,846 for Mr. Kalra, $97,304 for Mr. Ben-Natan, $94,211 for Mr. Haltmayer and $83,528 for Mr. Warren. For 2017, the amounts in this column also include fully-vested performance-based RSUs that were granted in 2017 and in the first quarter of 2018 to satisfy amounts earned for achieving quarterly and full-year performance targets under the Company’s 2017 incentive bonus plans.

Amounts earned by Mr. Harshman for first-half 2018 were paid in cash and are included in this column. This column also reflects cash amounts earned by all NEOs for second-half 2018 achievement and full-year over-achievement under the Company’s 2018 incentive bonus plans, and actual payment of the earned amounts occurred at the end of 2018 and in the first quarter of 2019.

(1	)	Under our 1995 Plan, our RSU awards granted through 2012 vested 25% upon completion of 12 months of service and 1/8 per six month period thereafter, contingent upon continued employment. In 2013, a two-year vesting schedule was introduced, with 50% vesting upon completion of 12 months of service and 1/4 vesting per six month period thereafter, contingent upon continued employment. In 2015, a three-year vesting schedule was introduced, with 40% vesting upon completion of 12 months of service, and 15% vesting per six month period thereafter, contingent upon continued employment. In 2016, a two-year vesting schedule was re-introduced, with 50% vesting upon completion of 12 months of service, and 12.5% vesting per three month period thereafter, contingent upon continued employment. In 2017, a three-year vesting schedule was introduced, with 40% vesting upon completion of 12 months of service, and 7.5% of shares vesting quarterly thereafter, contingent upon continued employment. Exceptions to this vesting are identified in footnotes 10 and 15, where the grants had a two-year vesting schedule, with 50% vesting upon completion of 12 months of service, and 12.5% vesting per three month period thereafter, contingent upon continued employment.
(2	)	The value of the shares not vested is the number of shares multiplied by $4.72, the closing price of the Company’s stock on December 31, 2018.
(3	)	Under our Stock Plan, our stock options have generally vested 25% upon completion of 12 months of service and 1/48 per month thereafter and expire after seven years, contingent upon continued employment. Exceptions to this vesting are identified in footnotes 18, 19, 21 and 23 below, where the grants have 33.33% vesting upon completion of 12 months of service and 1/36 per month thereafter.
(4	)	As of December 31, 2018, no shares subject to this SPRSU were vested. The March 20, 2017 and June 8, 2017 SPRSU grants with vesting based on the closing price of the Company’s common stock have the following conditions: if the closing price as quoted on the NASDAQ Stock Market equals or exceeds certain stock price thresholds for at least 20 consecutive trading days (the "Minimum Trading Period"), then 25% of the SPRSUs will vest on the final day of the Minimum Trading Period. If the stock price threshold for which the Minimum Trading Period has been satisfied exceeds one or more other stock price thresholds for which the SPRSU award has not already vested, then the vesting associated with all such stock price thresholds shall occur as of the close of market on the final day of the Minimum Trading Period.

If the stock price threshold for which the Minimum Trading Period has been satisfied exceeds the other stock price threshold for which the SPRSU award has not already vested, then the vesting associated with both such stock price thresholds shall occur as of the close of market on the final day of the Minimum Trading Period.
(8	)	As of December 31, 2018, no shares subject to this performance-based restricted stock unit award were vested.

OPTIONS EXERCISED AND STOCK VESTED DURING 2018

The following table summarizes (i) the options exercised during the year ended December 31, 2018 by our NEOs and the value realized upon exercise (which is the number of shares under each option exercised multiplied by (a) the closing price of the Common Stock on the day of exercise, less (b) the exercise price of the respective option), and (ii) the number of shares of Common Stock acquired by our NEOs, and the value of such shares, upon the vesting of RSUs and performance-based RSUs during the year ended December 31, 2018 (where the value realized on vesting is determined by multiplying the number of vested shares by the closing price of the Common Stock on the vesting date):

	Option Awards			Stock Awards
Name	Number of Shares Acquired on Exercise	Value Realized on Exercise		Number of Shares Acquired on Vesting	Value Realized on Vesting
Patrick J. Harshman	—	$	—	231,931	$	886,600

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE-IN-CONTROL

The Company does not have employment agreements with any of its NEOs. As described in the Compensation Discussion & Analysis above, under the terms of the respective NEO’s change of control severance agreement, in the event of termination of the NEO other than for cause (as defined in the relevant change of control severance agreement) within 18 months following a change in control of the Company, the NEO will be entitled to certain payments. The Company has entered into change of control severance agreements with each of the NEOs. Based on a hypothetical termination date of December 31, 2018, the respective amounts paid to the NEOs in the event of termination following a change of control would have been:

Name	Salary ($)	Bonus ($)	Value of Unvested Restricted Stock Units (1)(2)	Value of Unvested Stock Options (1)(2)	Other (3)	Total (4)
Patrick J. Harshman	$1,029,000	$1,286,250	$2,197,948	$23,409	$24,823	$4,561,430
Sanjay Kalra	320,000	176,000	761,690	—	28,173	1,285,863
Nimrod Ben-Natan	333,606	200,164	1,090,320	7,023	87,017	1,718,130
Neven Haltmayer	329,321	187,713	709,378	7,023	28,387	1,261,822
Tim Warren	301,726	165,949	501,500	3,726	9,500	982,401

(1)	The amounts in this column represent the value which would have been realized by the acceleration of unvested RSUs, all unvested performance-based RSUs and unvested stock options, calculated by, in the case of options, multiplying the number of shares subject to acceleration by the difference between $4.72, the closing price of our Common Stock on December 31, 2018 and the exercise price of the respective option. The value of RSUs and performance-based RSUs is the number of shares multiplied by the closing price of the Common Stock on December 31, 2018.
(2)	The Company’s change of control severance agreements have a provision that all unvested RSUs and options will be fully accelerated upon termination of employment within 18 months following a change of control.
(3)	The amounts in the column “Other” represent the maximum cost of continuing health, dental and life insurance benefits and outplacement fees.
(4)	The Company’s change of control severance agreements have a provision that payments will either be made in full, with the executive paying any applicable Section 4999 excise taxes as the result of the applicable of Section 280G of the Code, or the payments will be reduced to a level that does not trigger the Section 4999 excise tax as the result of the applicable of Section 280G of the Code, whichever results in a greater amount. The amounts shown in the table assume that the executive would elect to receive full payment and pay any applicable excise taxes.

Comcast’s right to exercise the Warrant is subject to certain vesting triggers relating to the execution of the Warrant, certain pricing elections by Comcast, the successful completion of field trials of certain of our products, and certain payments by Comcast for our products and services. (See Note 16, “Warrants,” to our Consolidated Financial Statements included in our 2018 Annual Report for additional information).

CEO PAY RATIO

Pursuant to Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to Harmonic’s CEO, Patrick Harshman. The paragraphs that follow describe our methodology and the resulting CEO pay ratio.

Measurement Date

We identified the median employee using our employee population as of December 31, 2018, which is a date within the last 3 months of our last completed fiscal year.

Consistently Applied Compensation Measure (CACM)

Under the relevant rules, we were required to identify the median employee by use of a “consistently applied compensation measure,” or CACM. We chose a CACM that closely approximates the annual total target direct compensation of our employees. Specifically, we identified the median employee by looking at annual base pay, bonus or commission opportunity at target, and the grant date fair value for standard equity awards. We adjusted the compensation paid to part-time employees by annualizing base pay and any bonus or commission target, as applicable, to calculate what they would have been paid on a full-time basis. With respect to our non-U.S. employees, we converted all compensation amounts to U.S. dollar using the applicable currency exchange rate as of February 28, 2019.

Methodology and Pay Ratio

After applying our CACM methodology, we determined our median employee. The 2018 total annual compensation of our median employee was $95,958.

Our CEO’s total 2018 compensation as reported in the Summary Compensation Table was $2,343,074. Therefore, the ratio of the annual total compensation of the Company’s CEO to the annual total compensation of the median employee is 24:1.

As of December 31, 2018, approximately 32% of our global workforce was based in the United States and approximately 68% was based outside of the United States, with approximately 49% of our employees located in the Europe-Middle-East (EMEA) region and 17% in the Asia-Pacific (APAC) region. If our median employee was determined using only our U.S. employees as of December 31, 2018, the 2018 compensation of our median employee would be $147,034 and our CEO to median employee pay ratio would be 16:1.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with Item 402(u). Neither the Compensation Committee nor management of the company used the pay ratio measure in making compensation decisions.

(ar)“Subsidiary” means a “subsidiary corporation”, whether now or hereafter existing, as defined in Section 424(f) of the Code.

(as)“Total Shareholder Return” means the total return (change in share price plus reinvestment of any dividends) of a Share.

3)Stock Subject to the Plan.

(a)General. Subject to the provisions of Section 17 of the Plan, the maximum aggregate number of Shares which may be issued under the Plan is 43,900,000 Shares, plus any shares subject to options under the Company’s 1999 Non-Statutory Stock Plan that were outstanding as of May 27, 2004 that expire unexercised, up to an additional maximum of 1,800,000 Shares. The Shares may be authorized, but unissued, or reacquired Common Stock.

(b)Full Value Awards. Any Shares subject to Awards granted with an exercise price less than the Fair Market Value on the grant date of grant will be counted against the numerical limits of this Section 3 as (a) one and one-half (1.5) Shares for every one (1) Share subject thereto with respect to any such Award granted prior to June [5], 2019 and (b) one (1) Share for every one (1) Share

A-3

subject thereto with respect to any such Award granted on or after June [5], 2019. Further, if Shares subject to any such Award do not vest and therefore are forfeited to or repurchased by the Company and would therefore return to the Plan pursuant to Section 3(c), (a) one and one-half (1.5) times the number of Shares so forfeited or repurchased with respect to any such Award granted prior to June [5], 2019] and (b) one (1) times the number of Shares with respect to any such Award granted on or after June [5], 2019] will return to the Plan and will again become available for issuance.

(c)Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full or, with respect to Restricted Stock. Restricted Stock Units, Performance Shares, Performance Units or Deferred Stock Units, is forfeited to or repurchased by the Company by virtue of it not vesting, the unpurchased Shares (or for Awards other than Options and Stock Appreciation Rights, the forfeited or repurchased Shares) which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). Upon exercise of a Stock Appreciation Right settled in Shares, the gross number of Shares covered by the portion of the Award so exercised will cease to be available under the Plan. 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 unvested Shares of Restricted Stock, Restricted Stock Units, Performance Shares, Performance Units or Deferred Stock Units are repurchased by the Company or are forfeited to the Company by virtue of their not vesting, such Shares will become available for future grant under the Plan. Shares used to pay the withholding tax related to an Award or to pay for the exercise price of an Award will not 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 provisions of this Section 3(c), subject to adjustment provided in Section 17(a), 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, any Shares that become available for issuance under the Plan under this Section 3(c).

4)Administration of the Plan.

(a)Procedure.

(i)Multiple Administrative Bodies. The Plan may be administered by different Committees with respect to different groups of Employees or Consultants.

(ii)Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder on or before November 2, 2017 as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan shall be administered by a Committee of two 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 shall be structured to satisfy the requirements for exemption under Rule 16b-3.

(iv)Other Administration. Other than as provided above, the Plan shall be administered by (A) the Board or (B) a Committee, which committee shall 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 shall have the authority, in its discretion:

(i)to determine the Fair Market Value of the Common Stock, in accordance with Section 2(u) of the Plan;

(ii)to select the Consultants and Employees to whom Awards may be granted hereunder;

(iii)to determine whether and to what extent Awards or any combination thereof, are granted hereunder;

(iv)to determine the number of shares of Common Stock to be covered by each Award granted hereunder;

(v)to approve forms of agreement for use under the Plan;

(vi)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 Options or SARs may be exercised or other Awards vest (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 of Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine; but in no event may dividends be paid with respect to Awards prior to those Awards vesting;

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

A-4

(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 qualifying for preferred tax treatment under foreign tax laws;

(ix)to modify or amend each Award (subject to Section 19(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Options and SARs longer than is otherwise provided for in the Plan;

(x)to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Option or Stock Purchase Right previously granted by the Administrator;

(xi)to allow Participants to satisfy withholding tax obligations by electing to have the Company withhold from the Shares or cash to be issued upon exercise, vesting of an Award (or distribution of a Deferred Stock Unit) that number of Shares or cash having a Fair Market Value not in excess of the maximum statutory amount required to be withheld. The Fair Market Value of any Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares or cash withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable;

(xii)to determine the terms and restrictions applicable to Awards; 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 shall be final and binding on all Participants and any other holders of Awards.

5)Eligibility. Restricted Stock, Performance Shares, Performance Units, Stock Appreciation Rights, Deferred Stock Units and Nonstatutory Stock Options may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

6)Limitations.

(a)Each Option shall be designated in the Notice of Grant as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value:

(i)of Shares subject to a Participant’s Incentive Stock Options granted by the Company, any Parent or Subsidiary, which

(ii)become exercisable for the first time during any calendar year (under all plans of the Company or any Parent or Subsidiary)

(iii)exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time of grant.

(b)Neither the Plan nor any Award shall confer upon a Participant any right with respect to continuing the Participant’s employment with the Company or its Subsidiaries, nor shall they interfere in any way with the Participant’s right or the Company’s or Subsidiary’s right, as the case may be, to terminate such employment at any time, with or without cause or notice.

(c)The following limitations shall apply to Awards granted under the Plan:

(i)No Participant shall be granted, in any fiscal year of the Company, Options and Stock Appreciation Rights to purchase more than 800,000 Shares.

(ii)No Participant shall be granted, in any fiscal year of the Company, Restricted Shares and Performance Shares covering more than 800,000 Shares.

(iii)The foregoing limitations shall be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 17.

7)Term of Plan. Unless terminated earlier, the Plan shall continue in effect until March 1, 2025.

A-5

8)Term of Option. The term of each Option shall be stated in the Notice of Grant; provided, however, that in no event shall the term be more than: (i) ten (10) years from the date of grant for options granted prior to the 2012 annual meeting of stockholders; and (ii) seven (7) years from the date of grant for options granted on or following the 2012 annual meeting of stockholders. 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 voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Notice of Grant.

9)Option Exercise Price and Consideration.

(a)Exercise Price; No Exchange Program. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator, subject to the following:

(i)In the case of an Incentive Stock Option

1.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 shall be no less than 110% of the Fair Market Value per Share on the date of grant.

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

(ii)In the case of a Nonstatutory Stock Option, the per Share exercise price shall be no less than 100% of the Fair Market Value per share on the date of grant.

(iii)Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a merger or other corporate transaction.

(iv)The exercise price for an Option may not be reduced without the consent of the Company’s stockholders. This shall include, without limitation, a repricing of the Option as well as an Option exchange program whereby the Participant agrees to cancel an existing Option in exchange for cash, an Option, SAR or other Award.

(b)Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be satisfied before the Option may be exercised. In so doing, the Administrator may specify that an Option may not be exercised until the completion of a service period.

(c)Form of Consideration. The Administrator shall 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 shall determine the acceptable form of consideration at the time of grant. Subject to Applicable Laws, such consideration may consist entirely of:

(i)cash;

(ii)check;

(iii)other Shares which (A) in the case of Shares acquired upon exercise of an option, have been owned by the Participant for any time required by the Administrator to avoid adverse financial accounting consequences, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised;

(iv)delivery of a properly executed exercise notice together with such other documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale proceeds required to pay the exercise price;

(v)any combination of the foregoing methods of payment; or

(vi)such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws.

10)Exercise of Option.

(a)Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall 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 Option Agreement.

A-6

(i)An Option may not be exercised for a fraction of a Share.

(ii)An Option shall be deemed exercised when the Company receives: (i) written notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall 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 stock certificate evidencing such Shares is 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 shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate 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 stock certificate is issued, except as provided in Section 17 of the Plan.

(iii)Exercising an Option in any manner shall 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.

(b)Termination of Employment or Consulting Relationship. Upon termination of a Participant’s Continuous Status as an Employee or Consultant, other than upon the Participant’s death or Disability, the Participant may exercise his or her Option, but only within such period of time as is specified in the Notice of Grant, and only to the extent that the Participant was entitled to exercise it at the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant). In the absence of a specified time in the Notice of Grant, the Option shall remain exercisable for three months following the Participant’s termination of Continuous Status as an Employee or Consultant. In the case of an Incentive Stock Option, such period of time shall not exceed three months from the date of termination. If, at the date of termination, the Participant is not entitled to exercise his or her entire Option, the Shares covered by the unexercisable portion of the Option shall 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 shall terminate, and the Shares covered by such Option shall revert to the Plan.

(c)Disability of Participant. In the event that a Participant’s Continuous Status as an Employee or Consultant terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option at any time within twelve (12) months from the date of such termination, but only to the extent that the Participant was entitled to exercise it at the date of such termination (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant). If, at the date of termination, the Participant is not entitled to exercise his or her entire Option, the Shares covered by the unexercisable portion of the Option shall revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(d)Death of Participant. In the event of the death of a Participant, the Option may be exercised at any time within twelve (12) months following the date of death (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Participant’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent that the Participant was entitled to exercise the Option at the date of death. If, at the time of death, the Participant was not entitled to exercise his or her entire Option, the Shares covered by the unexercisable portion of the Option shall immediately revert to the Plan. If, after death, the Participant’s estate or a person who acquired the right to exercise the Option by bequest or inheritance does not exercise the Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

11)Stock Appreciation Rights.

(a)Grant of SARs. Subject to the terms and conditions of the Plan, SARs may be granted to Participants at any time and from time to time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the number of SARs granted to any Participant.

(b)Exercise Price and other Terms; No Exchange Program. Subject to Section 6(c) of the Plan, the Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of SARs granted under the Plan; provided, however, that: (i) no SAR granted prior to the 2012 annual meeting of stockholders may have a term of more than ten (10) years from the date of grant, (ii) no SAR granted on or following the 2012 annual meeting of stockholders may have a term of more than seven (7) years from the date of grant, and (iii) the per share exercise price of a SAR shall be no less than 100% of the Fair Market Value per share on the grant date. Notwithstanding the foregoing, SARs may be granted with a per share exercise price of less than 100% of the Fair Market Value per share on the date of grant pursuant to a merger or other corporate transaction. The exercise price for the Shares or cash to be issued pursuant to an already granted SAR may not be changed without the consent of the Company’s stockholders. This shall include, without limitation, a repricing of the SAR as well as an SAR exchange program whereby the Participant agrees to cancel

A-7

an existing SAR in exchange for cash, an Option, SAR or other Award. No dividends may be paid with respect to any SAR prior to the SAR vesting.

(c)Payment of SAR Amount. Upon exercise of a SAR, a Participant shall 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 SAR is exercised.

(d)Payment upon Exercise of SAR. At the discretion of the Administrator, payment for a SAR may be in cash, Shares or a combination thereof

(e)SAR Agreement. Each SAR grant shall be evidenced by an Award Agreement that shall specify the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, shall determine.

(f)Expiration of SARs. A SAR granted under the Plan shall expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement.

(g)Termination of Employment or Consulting Relationship. Upon termination of a Participant’s Continuous Status as an Employee or Consultant, other than upon the Participant’s death or Disability, the Participant may exercise his or her SAR, but only within such period of time as is specified in the Notice of Grant, and only to the extent that the Participant was entitled to exercise it at the date of termination (but in no event later than the expiration of the term of such SAR as set forth in the Notice of Grant). In the absence of a specified time in the Notice of Grant, the SAR shall remain exercisable for three months following the Participant’s termination of Continuous Status as an Employee or Consultant. If, at the date of termination, the Participant is not entitled to exercise his or her entire SAR, the Shares covered by the unexercisable portion of the SAR shall revert to the Plan. If, after termination, the Participant does not exercise his or her SAR within the time specified by the Administrator, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

(h)Disability of Participant. In the event that a Participant’s Continuous Status as an Employee or Consultant terminates as a result of the Participant’s Disability, the Participant may exercise his or her SAR at any time within twelve (12) months from the date of such termination, but only to the extent that the Participant was entitled to exercise it at the date of such termination (but in no event later than the expiration of the term of such SAR as set forth in the Notice of Grant). If, at the date of termination, the Participant is not entitled to exercise his or her entire SAR, the Shares covered by the unexercisable portion of the SAR shall revert to the Plan. If, after termination, the Participant does not exercise his or her SAR within the time specified herein, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

(i)Death of Participant. In the event of the death of a Participant, the SAR may be exercised at any time within twelve (12) months following the date of death (but in no event later than the expiration of the term of such SAR as set forth in the Notice of Grant), by the Participant’s estate or by a person who acquired the right to exercise the SAR by bequest or inheritance, but only to the extent that the Participant was entitled to exercise the SAR at the date of death. If, at the time of death, the Participant was not entitled to exercise his or her entire SAR, the Shares covered by the unexercisable portion of the SAR shall immediately revert to the Plan. If, after death, the Participant’s estate or a person who acquired the right to exercise the SAR by bequest or inheritance does not exercise the SAR within the time specified herein, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

12)Restricted Stock.

(a)Grant of Restricted Stock. Subject to the terms and conditions of the Plan, Restricted Stock may be granted to Participants at any time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine (i) the number of Shares subject to a Restricted Stock award granted to any Participant (subject to the annual limitation under Section 6(c)(ii) of the Plan), and (ii) the conditions that must be satisfied, which typically will be based principally or solely on continued provision of services but may include a performance-based component, upon which is conditioned the grant or vesting of Restricted Stock. Restricted Stock shall be granted in the form of units to acquire Shares. Each such unit shall be the equivalent of one Share for purposes of determining the number of Shares subject to an Award. Until the Shares are issued, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the units to acquire Shares.

(b)Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of Restricted Stock granted under the Plan. Restricted Stock grants shall be subject to the terms, conditions, and restrictions determined by the Administrator at the time the stock is awarded. The Administrator may require the recipient to sign a

A-8

Restricted Stock Award agreement as a condition of the award. Any certificates representing the Shares of stock awarded shall bear such legends as shall be determined by the Administrator.

(c)Restricted Stock Award Agreement. Each Restricted Stock grant shall be evidenced by an agreement that shall specify the purchase price (if any) and such other terms and conditions as the Administrator, in its sole discretion, shall determine; provided; however, that if the Restricted Stock grant has a purchase price, such purchase price must be paid no more than ten (10) years following the date of grant.

13)Performance Shares.

(a)Grant of Performance Shares. Subject to the terms and conditions of the Plan, Performance Shares may be granted to Participants at any time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine (i) the number of Shares subject to a Performance Share award granted to any Participant (subject to the annual limitation under Section 6(c)(ii) of the Plan), and (ii) the conditions that must be satisfied, which typically will be based principally or solely on achievement of performance milestones but may include a service-based component, upon which is conditioned the grant or vesting of Performance Shares. Performance Shares shall be granted in the form of units to acquire Shares. Each such unit shall be the equivalent of one Share for purposes of determining the number of Shares subject to an Award. Until the Shares are issued, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the units to acquire Shares.

(b)Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of Performance Shares granted under the Plan. Performance Share grants shall be subject to the terms, conditions, and restrictions determined by the Administrator at the time the stock is awarded, which may include such performance-based milestones as are determined appropriate by the Administrator. The Administrator may require the recipient to sign a Performance Shares agreement as a condition of the award. Any certificates representing the Shares of stock awarded shall bear such legends as shall be determined by the Administrator.

(c)Performance Share Award Agreement. Each Performance Share grant shall be evidenced by an agreement that shall specify such other terms and conditions as the Administrator, in its sole discretion, shall determine.

14)Performance Units.

(a)Grant of Performance Units. Performance Units are similar to Performance Shares, except that they shall be settled in a cash equivalent to the Fair Market Value of the underlying Shares, determined as of the vesting date. Subject to the terms and conditions of the Plan, Performance Units may be granted to Participants at any time and from time to time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the conditions that must be satisfied, which typically will be based principally or solely on achievement of performance milestones but may include a service-based component, upon which is conditioned the grant or vesting of Performance Units. Performance Units shall be granted in the form of units/rights to acquire Shares. Each such unit/right shall be the cash equivalent of one Share of Common Stock. No right to vote or receive dividends or any other rights as a shareholder shall exist with respect to Performance Units or the cash payable thereunder.

(b)Number of Performance Units. The Administrator will have complete discretion in determining the number of Performance Units granted to any Participant, provided that during any fiscal year of the Company, no Participant shall receive Performance Units having an initial value greater than $1,000,000, except that such Participant may receive Performance Units in a fiscal year of the Company in which his or her service as a Participant first commences with an initial value no greater than $2,000,000.

(c)Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of Performance Units granted under the Plan. Performance Unit grants shall be subject to the terms, conditions, and restrictions determined by the Administrator at the time the stock is awarded, which may include such performance-based milestones as are determined appropriate by the Administrator. The Administrator may require the recipient to sign a Performance Unit agreement as a condition of the award. Any certificates representing the Shares awarded shall bear such legends as shall be determined by the Administrator.

(d)Performance Unit Award Agreement. Each Performance Unit grant shall be evidenced by an agreement that shall specify such terms and conditions as the Administrator, in its sole discretion, shall determine.

15)Deferred Stock Units.

(a)Description. Deferred Stock Units shall consist of a Restricted Stock, Performance Share or Performance Unit Award that the Administrator, in its sole discretion permits to be paid out in installments or on a deferred basis, in accordance with rules and procedures established by the Administrator.

A-9

(b)Annual Limits. Deferred Stock Units shall be subject to the annual limits applicable to the underlying Restricted Stock, Performance Share or Performance Unit Award.

16)Non-Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the recipient, only by the recipient. If the Administrator makes an Award transferable, such Award shall contain such additional terms and conditions as the Administrator deems appropriate. In no event shall an Award be transferred to a third party for value, unless previously approved by the Company’s stockholders.

17)Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale.

(a)Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Award, the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Award, as well as the price per share of Common Stock covered by each such outstanding Award and the annual share issuance limits under Sections 6(c), 12(a) and 13(a) shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Compensation Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Award.

(b)Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for a Participant to have the right to exercise his or her Option or SAR until ten (10) days prior to such transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option or forfeiture rights applicable to any Award shall lapse 100%, and that any Award vesting shall accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised (with respect to Options and SARs) or vested (with respect to other Awards), an Award will terminate immediately prior to the consummation of such proposed action.

(c)Merger or Asset Sale.

(i)Stock Options and SARs. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Option and SAR shall be assumed or an equivalent option or SAR substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Option or SAR, the Participant shall fully vest in and have the right to exercise the Option or SAR as to all of the Awarded Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or SAR becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Participant in writing or electronically that the Option or SAR shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Option or SAR shall terminate upon the expiration of such period. For the purposes of this paragraph, the Option or SAR shall be considered assumed if, following the merger or sale of assets, the option or stock appreciation right confers the right to purchase or receive, for each Share of Awarded Stock subject to the Option or SAR immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets 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 merger or sale of assets 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 the Option or SAR, for each Share of Awarded Stock subject to the Option or SAR, 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 merger or sale of assets.

(ii)Restricted Stock, Performance Shares, Performance Units and Deferred Stock Units. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Restricted Stock, Performance Share, Performance Unit and Deferred Stock Unit award shall be assumed or an equivalent Restricted Stock, Performance Share, Performance Unit and Deferred Stock Unit award substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Restricted Stock, Performance Share, Performance Unit or Deferred Stock Unit award, the Participant shall fully vest in the Restricted Stock, Performance

A-10

Share, Performance Unit or Deferred Stock Unit including as to Shares (or with respect to Performance Units, the cash equivalent thereof) which would not otherwise be vested. For the purposes of this paragraph, a Restricted Stock, Performance Share, Performance Unit and Deferred Stock Unit award shall be considered assumed if, following the merger or sale of assets, the award confers the right to purchase or receive, for each Share (or with respect to Performance Units, the cash equivalent thereof) subject to the Award immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets 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 merger or sale of assets 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, for each Share and each unit/right to acquire a Share subject to the 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 merger or sale of assets.

18)Date of Grant. The date of grant of an Award shall be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination shall be provided to each Participant within a reasonable time after the date of such grant.

19)Amendment and Termination of the Plan.

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

(b)Stockholder Approval. The Company shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply Section 422 of the Code (or any successor rule or statute or other applicable law, rule or regulation, including the requirements of any exchange or quotation system on which the Common Stock is listed or quoted). Such stockholder approval, if required, shall be obtained in such a manner and to such a degree as is required by the applicable law, rule or regulation.

(c)Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall 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.

20)Conditions Upon Issuance of Shares.

(a)Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of the Award or the issuance and delivery of such Shares (or with respect to Performance Units, the cash equivalent thereof) shall comply with Applicable Laws and shall 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 or receipt of an Award, the Company may require the person exercising or receiving such Award to represent and warrant at the time of any such exercise or receipt 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.

21)Liability of Company.

(a)Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

(b)Grants Exceeding Allotted Shares. If the Awarded Stock covered by an Award exceeds, as of the date of grant, the number of Shares which may be issued under the Plan without additional stockholder approval, such Award shall be void with respect to such excess Awarded Stock, unless stockholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 19(b) of the Plan.

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

3) Stock Subject to the Plan. Subject to the provisions of Section 10 of the Plan, the maximum aggregate number of Shares which may be issued under the Plan is 3,150,000 Shares (the “Pool”). The Shares may be authorized, but unissued, or reacquired Common Stock. Any Shares subject to Options shall be counted against the numerical limits of this section 3 as one Share for every Share subject thereto. Any Shares of Restricted Stock Units granted prior to [June 5], 2019 shall be counted against the numerical limits of this section 3 as one and one half (1.5) Shares for every one Share subject thereto and any Shares of Restricted Stock Units granted on or after [June 5], 2019 shall be counted against the numerical limits of this section 3 as one Share for every one Share subject thereto.

Restricted Stock Units that do not vest and thus are forfeited back to the Company shall become available for future grant or sale under the Plan (unless the Plan has terminated). Shares of Restricted Stock Units that vest shall not in any event be returned to the Plan and shall not become available for future distribution under the Plan.

B-2

If an Option expires or becomes unexercisable without having been exercised in full, the unpurchased Shares which were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). Shares that have actually been issued under the Plan shall not be returned to the Plan and shall not become available for future distribution under the Plan.

4) Administration and Grants of Awards under the Plan. The Board may make discretionary grants of Options or Restricted Stock Units to any Outside Director under this Plan. Moreover, Outside Directors shall receive the following automatic grants (unless otherwise determined by the Board in its sole discretion):

a) Initial Grant. Each Outside Director who first becomes a Outside Director on or after the Company’s 2008 annual stockholders’ meeting (excluding a former Inside Director who ceases to be an Inside Director but who remains a Director), shall be entitled to receive, as of the date that the individual first is appointed or elected as a Outside Director, an Option or Restricted Stock Unit, or a combination of an Option and a Restricted Stock Unit, as determined on or prior to the grant date by the Board in its sole discretion.

b) Ongoing Grants. On the date each Outside Director is reelected to the Board by the stockholders of the Company at the Company’s annual meeting of stockholders or otherwise; each Outside Director who has served on the Board for at least six months on that date shall be granted an Option or Restricted Stock Unit, or a combination of an Option and a Restricted Stock Unit, as determined on or prior to the grant date by the Board in its sole discretion.

c) Terms and Conditions of Options and RSUs. Subject to the other provisions of this Plan, the terms and conditions of any Options and Restricted Stock Units granted under this Plan, including vesting, shall be determined by the Board in its sole discretion and set forth in an Option or Restricted Stock Unit agreement; provided, however, that (i) the term of any Option may not exceed seven (7) years, and (ii) any Option shall have a per Share exercise price not less than 100% of the Fair Market Value on the grant date.

5) Eligibility. Options and Restricted Stock Units may be granted only to Outside Directors.

The Plan shall not confer upon any Director any right with respect to continuation of service as a Director or nomination to serve as a Director, nor shall it interfere in any way with any rights which the Director or the Company may have to terminate the Director’s relationship with the Company at any time.

6) Term of Plan. The Plan shall continue in effect until March 1, 2025, unless sooner terminated under Section 11 of the Plan.

7) Form of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall consist of:

a) cash;

b) check;

c) other shares which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised;

d) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan; or

e) any combination of the foregoing methods of payment.

8) Exercise of Option.

a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable at such times as are set forth in Section 4 hereof; provided, however, that no Options shall be exercisable until stockholder approval of the Plan has been obtained.

i) An Option may not be exercised for a fraction of a Share.

ii) An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may consist of any consideration and method of payment allowable under Section 7 of the Plan. Until the issuance (as evidenced

B-3

by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. A share certificate for the number of Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 10 of the Plan.

iii) Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be 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.

b) Termination of Continuous Status as a Director. Subject to Section 10 hereof, in the event an Optionee’s status as a Director terminates (other than upon the Optionee’s death or Disability), the Optionee may exercise his or her Option, but only within three (3) months (extended to three (3) years for Options granted on or after May 27, 2004) following the date of such termination, and only to the extent that the Optionee was entitled to exercise it on the date of such termination (but in no event later than the expiration of the Option’s term as set forth in Section 4 hereof). To the extent that the Optionee was not vested as to his or her entire Option on the date of such termination, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

c) Disability of Optionee. In the event Optionee’s status as a Director terminates as a result of Disability, the Optionee may exercise his or her Option, but only within twelve (12) months following the date of such termination (extended to three (3) years for Options granted on or after May 27, 2004), and only to the extent that the Optionee was entitled to exercise it on the date of such termination (but in no event later than the expiration of the Option’s term as set forth in Section 4 hereof). To the extent that the Optionee was not vested as to his or her entire Option on the date of termination, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

d) Death of Optionee. In the event of an Optionee’s death, the Optionee’s estate or a person who acquired the right to exercise the Option by bequest or inheritance may exercise the Option, but only within twelve (12) months following the date of death (extended to three (3) years for Options granted on or after May 27, 2004), and only to the extent that the Optionee was entitled to exercise it on the date of death (but in no event later than the expiration of the Option’s term as set forth in Section 4 hereof). To the extent that the Optionee was not vested as to his or her entire Option on the date of death, the Shares covered by the unvested portion of the Option shall revert to the Plan. To the extent that the Optionee’s estate or a person who acquired the right to exercise such Option does not exercise such Option (to the extent otherwise so entitled) within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

9) Non-Transferability of Options and Restricted Stock Units. Options or Restricted Stock Units may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and, with respect to the Option, may be exercised, during the lifetime of the Optionee, only by the Optionee. In no event shall an Option or Restricted Stock Unit be transferred to a third party for value, unless previously approved by the Company’s stockholders.

10) Adjustments Upon Changes in Capitalization, Dissolution, Merger or Change-in-Control.

a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option and Restricted Stock Unit, the number of Shares which have been authorized for issuance under the Plan but as to which no awards have yet been granted or which have been returned to the Plan upon cancellation or expiration of an award, as well as the price per Share covered by each such outstanding Option shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option or the number of shares subject to a Restricted Stock Unit.

b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, then to the extent that (i) an Option has not been previously exercised, or (ii) a Restricted Stock Unit has not vested, it shall terminate immediately prior to the consummation of such proposed action.

B-4

c) Merger or Change-in-Control. In the event of a merger of the Company with or into another corporation or a Change-in-Control of the Company, outstanding Options may be assumed or equivalent awards may be substituted by the successor corporation or a Parent or Subsidiary thereof (the “Successor Corporation”). If an option is assumed or substituted for, the Option or equivalent option shall continue to be exercisable as provided in Section 4 hereof for so long as the Optionee serves as a Director or a director of the Successor Corporation. In addition, whether or not the Successor Corporation assumes an outstanding Option or substitutes for it an equivalent award, immediately prior to a Change-in-Control each Option or option shall become fully vested and exercisable, including as to Shares for which it would not otherwise be exercisable. Thereafter, the Option or option shall remain exercisable in accordance with Section 8(b) through (d) above. Similarly, immediately prior to a Change-in-Control each Restricted Stock Unit shall become 100% vested and payable immediately.

For the purposes of this Section 10(c), an Option shall be considered assumed if, following the merger or Change-in-Control, the Option confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option immediately prior to the merger or Change-in-Control, the consideration (whether stock, cash, or other securities or property) received in the merger or 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). If such consideration received in the merger or 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 the Option, for each Share of Optioned Stock subject to the Option, 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 merger or Change-in-Control.

11) Outside Director Limitations. No Outside Director may be paid, issued or granted, in any fiscal year of the Company, cash compensation and equity awards (including any Options or Restricted Stock Units issued under this Plan) with an aggregate value greater than $600,000 (with the value of each equity award based on its grant date fair value (determined in accordance with U.S. generally accepted accounting principles)). Any cash compensation paid or equity awards granted to an individual for his or her services as an Employee, or for his or her services as a consultant (other than as an Outside Director), will not count for purposes of the limitation under this Section 11.

12) Amendment and Termination of the Plan; No Repricing.

a) Amendment and Termination. The Board may at any time amend, alter, suspend, or discontinue the Plan, but no amendment, alteration, suspension, or discontinuation shall be made which would impair the rights of any Director under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with any applicable law, regulation or stock exchange rule, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required.

b) No Repricing. The exercise price for an Option may not be reduced without the consent of the Company’s stockholders. This shall include, without limitation, a repricing of the Option as well as an option exchange program whereby the Participant agrees to cancel an existing Option in exchange for another award.

13) Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option or the vesting of a Restricted Stock Unit unless the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, state securities laws, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an Option or settlement of a vested Restricted Stock Unit, the Company may require the person exercising such Option or receiving Shares in settlement of a Restricted Stock Unit to represent and warrant that the Shares are being purchased or received only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law.

Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

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

15) Option and RSU Agreements. Options and Restricted Stock Units shall be evidenced by written agreements in such form as the Board shall approve.
