PROXY STATEMENT

General information

Your vote is very important. For this reason, the board of directors of Patriot Scientific Corporation, a Delaware corporation (referred to as “we,” “us,” “our”, or “the Company,”), is soliciting your proxy to vote your shares of common stock at the 2017 Annual Meeting of Stockholders (the “annual meeting”), or at any continuation, postponement or adjournment thereof, for the purposes discussed in this proxy statement and in the accompanying Notice of Annual Meeting and any business properly brought before the annual meeting.

Why am I receiving these materials?

Proxies are solicited to give all stockholders of record an opportunity to vote on matters properly presented at the annual meeting. This proxy statement is being sent to all stockholders of record as of the close of business on April 2, 2018 in connection with the solicitation of proxies on behalf of the board of directors for use at the 2017 annual meeting of stockholders to be held on June 1, 2018. We intend to commence mailing this proxy statement and accompanying proxy card on or about April 18, 2018 to all stockholders entitled to vote at the annual meeting.

Our financial information

Our annual report to stockholders for the fiscal year ended May 31, 2017, including audited consolidated financial statements, has been mailed to the stockholders concurrently herewith, but such report is not incorporated in this proxy statement and is not deemed to be a part of the proxy solicitation material.

Who is eligible to vote?

Stockholders of Patriot Scientific Corporation, as recorded in our stock register at the close of business on April 2, 2018, can vote at the annual meeting. Each share of our common stock is entitled to one vote. As of April 2, 2018, there were 401,392,948 shares of our common stock outstanding and entitled to vote.

How do I vote?

There are three ways to vote by proxy:

(1) by internet;

(2) by telephone; or

(3) by mail.

If you vote by telephone or via the internet, please do not return a signed proxy card. If you choose to vote by mail, mark your proxy card enclosed with the proxy statement, date and sign it, and mail it in the postage-paid envelope.

You may also vote via the internet during the meeting. Stockholders attending via the internet will need to follow the instructions at www.virtualshareholdermeeting.com/PTSC2018 in order to vote at the meeting. Voting via the internet by a stockholder will revoke and replace any previous votes submitted.

4

Who pays the cost of proxy solicitation?

Our board of directors is soliciting the enclosed proxy. We will make proxy solicitations by electronic or regular mail and we will bear the costs of this solicitation. We will request banks, brokerage houses, nominees and other fiduciaries nominally holding shares of our common stock to forward the proxy soliciting materials to the beneficial owners of such common stock and to obtain authorization for the execution of proxies. We will, upon request, reimburse such parties for their reasonable expenses in forwarding proxy materials to the beneficial owners. In the event we decide to hire a service to solicit proxies, we would expect such service to cost approximately $15,000 plus reasonable and approved out-of-pocket expenses.

What is a proxy?

Giving us your proxy means you authorize us to vote your shares at the meeting in the manner you direct. You may vote for all, some or none of our director candidates. You may also vote for or against the other proposals or abstain from voting.

How do I specify how I want my shares voted?

If you are a registered stockholder, you can specify how you want your shares voted on each proposal by marking the appropriate boxes on the proxy card. Please review the voting instructions on the proxy card and read the entire text of the proposals and the positions of the board of directors in the proxy statement prior to marking your vote.

If your proxy card is signed and returned without specifying a vote or an abstention on a proposal, it will be voted according to the recommendation of the board of directors on that proposal. That recommendation is shown for each proposal on the proxy card.

How do I vote if I am a beneficial stockholder?

If you are a beneficial stockholder, you have the right to direct your broker or nominee on how to vote the shares. You should complete a Voting Instruction Card which your broker or nominee is obligated to provide you.

Brokerage firms have the authority under the various exchange rules to vote shares on routine matters for which their customers do not provide voting instructions.

What are broker “non-votes”?

Broker non-votes occur when nominees, such as banks and brokers holding shares on behalf of beneficial owners, do not receive voting instructions from the beneficial holders at least ten days before the meeting. If that happens, the nominees may vote those shares only on matters deemed “routine” by the New York Stock Exchange (“NYSE”), such as the ratification of auditors. Nominees cannot vote on non-routine matters unless they receive voting instructions from beneficial holders, resulting in so-called “broker non-votes.” The effect of “broker non-votes” on each of the proposals that will be considered at the Annual Meeting is described below and in our proxy statement.

We believe that the proposal for the ratification of our independent registered public accounting firm is considered to be a “routine” matter, and hence we do not expect that there will be a significant number of “broker non-votes” on such proposal.

The proposals to elect directors and approve, on an advisory basis, the compensation of the named executive officers are non-routine and the record owner may not vote your shares on these proposals if it does not get instructions from you. If you do not provide voting instructions on these two matters, a broker non-vote will occur. Broker non-votes, as well as “ABSTAIN” votes, will each be counted towards the presence of a quorum but will not be counted towards the vote total for any Proposal, other than Proposal No. 2. Accordingly, it is particularly important that beneficial owners instruct their brokers how they wish to vote their shares.

Can I revoke a proxy?

Stockholders of record may revoke their proxy at any time before the polls close by submitting a later-dated vote electronically at the annual meeting, via the internet, by telephone, by mail, or by delivering instructions to our Corporate Secretary before the annual meeting. If you hold shares through a brokerage firm, you may revoke any prior voting instructions by contacting that firm.

5

What is a quorum?

In order to carry on the business of the meeting, we must have a quorum. This means that at least a majority of the outstanding shares eligible to vote on the record date must be present at the meeting, either by proxy or in person. Abstentions and broker non-votes are counted as present at the meeting for determining whether we have a quorum. A broker non-vote occurs when a broker returns a proxy but does not vote on a particular proposal because the broker does not have discretionary voting power for that particular item and has not received voting instructions from the beneficial owner.

What are the Board of Directors’ voting recommendations?

For the reasons set forth in more detail later in the proxy statement, our board of directors unanimously recommends that you vote “For” for the following proposals:

Proposal No. 1 -	the election of our directors;
Proposal No. 2 -	the ratification of the Audit Committee’s appointment of KMJ Corbin & Company as our independent registered public accounting firm for current fiscal year 2018; and
Proposal No. 3 -	to approve, on an advisory basis, the compensation of the named executive officers.

How many votes are needed to have the proposals pass?

The board of directors will be elected by a favorable vote of a plurality of the shares of common stock present and entitled to vote, in person or by proxy, at the annual meeting. Accordingly, abstentions and “broker non-votes” (see above) as to the election of directors will not be counted in determining which nominees received the largest number of votes cast.

In order for Proposal Nos. 2 and 3 to pass, the affirmative vote of a majority of the shares present in person or by proxy and entitled to vote at the annual meeting is required for each proposal.

Only proxies and ballots indicating votes “FOR,” “AGAINST” or “ABSTAIN” on the proposals or providing the designated proxies with the right to vote in their judgment and discretion on the proposals are counted to determine the number of shares present and entitled to vote. Broker non-votes will not be counted towards the vote total on Proposal Nos. 1 and 3 although they will count toward the presence of a quorum. Abstentions as to a proposal will have the same effect as votes against a proposal.

Voting Results

We will report final results on Form 8-K which we will file with the Securities and Exchange Commission (“SEC”) no later than June 7, 2018.

What is “Householding” of annual meeting materials?

Some banks, brokers and other nominee record holders may be “householding” our proxy statements and annual reports. This means that only one copy of our proxy statement and annual report to stockholders may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you if you call or write us at our principal executive offices, 2038 Corte Del Nogal, Suite 141, Carlsbad, California, 92011-1478, Attn: Clifford L. Flowers, Corporate Secretary, telephone: (760) 795-8517. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker, or other nominee record holder, or you may contact us at the above address and telephone number.

PROPOSAL NUMBER 1

ELECTION OF DIRECTORS

The first proposal on the agenda for the annual meeting will be electing three directors to serve until the next annual meeting or until their successors are elected. Our bylaws provide that the number of our directors may be no less than three and no more than seven, with the exact number to be fixed as the board determines. The Board has currently fixed the number of directors at three. There are three nominees for the three currently authorized seats on our board of directors. Unless authority to vote for directors has been withheld in the proxy, the persons named in the enclosed proxy intend to vote at the annual meeting FOR the election of the nominees presented below.

Under Delaware law, the three nominees receiving the highest number of votes will be elected as directors at the Annual Meeting. As a result, proxies voted to “Withhold Authority” and broker non-votes will have no practical effect.

Each person nominated for election is currently serving as a director of the Company and has consented to serve as a director for the ensuing year. If any nominee becomes unavailable to serve for any reason before the election, then the enclosed proxy will be voted for the election of such substitute nominee, if any, as shall be designated by the board of directors. The board of directors has no reason to believe that any of the nominees will become unavailable to serve.

Information with respect to the number of shares of common stock beneficially owned by each director as of April 2, 2018 appears under the heading “Security Ownership of Certain Beneficial Owners, Directors and Management.” The name, age, years of service on our board of directors, and principal occupation and business experience of each director nominee is set forth below.

Director Qualifications – We believe that individuals who serve on our Board should possess the requisite education and experience to make a significant contribution to the Board and bring a range of skills, diverse perspectives and backgrounds to its deliberations; and should have the highest ethical standards, a strong sense of professionalism and dedication to serving the interests of our stockholders. The following are qualifications, experience and skills for Board members which are important to our business:

· Leadership Experience – We seek directors who demonstrate extraordinary leadership qualities. Strong leaders bring vision, diverse perspectives, and broad business insight to the company. They demonstrate practical management experience, skills for managing change, and knowledge of industries, geographies and risk management strategies relevant to the company.

· Finance Experience – We believe that all directors should possess an understanding of finance and related reporting processes. We also seek directors who qualify as “audit committee financial experts” as defined in rules of the SEC for service on the Audit Committee.

· Industry Experience – We seek directors who have relevant industry experience including: existing and new technologies, new or expanding businesses and a deep understanding of the Company’s business environments.

The Board of Directors concluded that Mr. Flowers should serve as a director due to his leadership and financial experience combined with the perspective and experience he brings as our current Chief Financial Officer, interim Chief Executive Officer and Corporate Secretary.

Vote Required; Board Recommendation

Directors are elected by plurality vote, meaning that (should there be more nominees than seats available) the nominees who receive the most votes will be elected for the term nominated, even if the number of votes received by any one or more nominees is less than a majority of the votes cast. Cumulative voting is not allowed in the election of directors. The Board recommends a vote in favor of each nominee set forth above.

CORPORATE GOVERNANCE

Our Board of Directors strongly believes in good corporate governance policies and practices. We expect to continue to seek and implement those corporate governance practices that we believe will promote a high level of performance from our Board of Directors, officers and employees. This section describes key corporate governance guidelines and practices that our Board has adopted. Copies of the following corporate governance documents are posted on our website at www.ptsc.com (the information contained on our website is not intended to be a part of this Proxy Statement): (1) Code of Ethics for Senior Financial Officers, (2) Charter of the Compensation Committee of the Board of Directors, and (3) Charter of the Audit Committee of the Board of Directors. If you would like a printed copy of any of these corporate governance documents, please send your request to Patriot Scientific Corporation, Attention: Corporate Secretary, 2038 Corte Del Nogal, Suite 141, Carlsbad, California 92011-1478.

Board of Directors

Our business is managed under the direction of our Board of Directors pursuant to the Delaware General Corporation Law and our Bylaws. Our Board of Directors has responsibility for establishing broad corporate policies and reviewing our overall performance. Among the primary responsibilities of our Board of Directors is the oversight of the management of our Company. Our directors remain informed of our business and management’s activities by reviewing documents provided to them before each board meeting and by attending presentations made by our chief executive officer and other members of management. The Board of Directors held five (5) formal meetings during the fiscal year ended May 31, 2017. Each incumbent director attended at least seventy-five percent (75%) of the meetings of the Board and of the committees on which the director served during the fiscal year ended May 31, 2017. In addition, members of the Board of Directors have access to our books, records and reports and independent auditors and advisors. Members of our management frequently interact with and are at all times available to our directors.

Director Independence

Under NASDAQ Marketplace Rule 5605(a)(2), a director will not be considered an “independent director” if, such director at any time during the past three years was an employee of the Company, or if a director (or a director’s family member) accepted compensation from the Company (other than compensation for board or board committee service) in excess of $120,000 during any twelve month period within the three years preceding the determination of independence. In addition, a director will not qualify as an “independent director” if, in the opinion of our Board of Directors, that person has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our Board of Directors has determined that each of the current directors, as well as those standing for re-election, are independent directors as defined by the NASDAQ Marketplace Rules governing the independence of directors, except for Clifford L. Flowers, our Chief Financial Officer and Interim Chief Executive Officer.

Our Audit and Compensation Committees are composed entirely of independent directors as required by applicable SEC and NASDAQ rules, including Rule 10A-3 under the Exchange Act of 1934, as amended (the “Exchange Act”).  In addition, there are no family relationships among any of the directors or executive officers of the Company.

Meetings of Independent Directors

The independent members of our Board of Directors have a practice of meeting in executive sessions without the presence of our management.

Board Committees

Our Board has two standing committees, the Audit Committee and the Compensation Committee. In addition, the Board from time to time establishes special purpose committees and utilizes an Executive Committee for executive transitions and other matters.

9

Audit Committee

Our Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Exchange Act, and is currently comprised of: Gloria H. Felcyn (Committee Chair) and Carlton M. Johnson, Jr. Each member of our Audit Committee is independent as defined under the applicable rules of the SEC and NASDAQ listing standards. The Board has determined that Gloria H. Felcyn, who serves on the Audit Committee, is an “audit committee financial expert” as defined in applicable SEC rules.

The Board has adopted a written charter for the Audit Committee, a copy of which is available on our website at www.ptsc.com. The responsibilities of the Audit Committee, as more fully described in its charter, include reviewing our: (i) financial reports and information, (ii) systems of internal controls, (iii) auditing, accounting and financial reporting processes, (iv) compliance with legal requirements, (v) independent auditor’s qualifications and independence, and (vi) internal audit function performance and that of our independent auditors. During the fiscal year ended May 31, 2017, the Audit Committee held a total of one (1) meeting.

Compensation Committee

Our Compensation Committee is currently comprised of the following, each of whom is independent as defined under applicable NASDAQ and SEC rules: Carlton M. Johnson, Jr. (Committee Chair) and Gloria H. Felcyn. In addition, each member is a “non-employee director” under Section 16 of the Exchange Act and an “outside director” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). During the fiscal year ended May 31, 2017, our Compensation Committee held one (1) meeting.

The Compensation Committee reviews and recommends to the Board the salaries, bonuses and perquisites of our executive officers. The Compensation Committee also reviews and recommends to the Board any new compensation or retirement plans. The Compensation Committee also reviews and approves corporate goals and objectives relevant to the compensation of our executive officers and evaluates their performance in light of these goals and objectives. The Compensation Committee operates under a charter, a copy of which is available on our website at www.ptsc.com. Changes to the charter are recommended by the Compensation Committee and must be approved by the Board.

Nominating Committee

We do not have a standing nominating committee and therefore do not have a nominating committee charter. We believe that it is appropriate not to have such a committee because the full Board participates in the decision of who to nominate to the Board.

Although we do not have a formal policy that outlines a process whereby stockholders may submit recommendations for Board nominees, we do facilitate communications from stockholders to our Board on any topic as described in the section of this Proxy Statement entitled “STOCKHOLDER PROPOSALS AND COMMUNICATIONS.” We believe that this process is adequate for considering the recommendations of our stockholders.

Qualifications for Director nominees are considered on a case by case basis, and may include factors including diversity in background, specific skills needed for committee roles, and in general experience that can complement the backgrounds of existing Board members. The Board has no specific process for identifying and evaluating nominees to the Board, but generally tries to identify individuals known to existing Board members who will provide a broad range of characteristics, including diversity, management skills, financial, technological and business experience, as well as the ability to commit the requisite time for preparation and attendance at regularly scheduled meetings and to participate in other matters necessary for good corporate governance. The Board has no policy regarding any differences in the manner in which it evaluates nominees recommended by a stockholder.

Board Leadership Structure

Our bylaws provide that the Chairman of the Board shall preside over all meetings of the Board of Directors. Our bylaws also state that the Chairman of the Board shall serve as the Chief Executive Officer unless determined otherwise by our Board. Since October 5, 2009 our Chief Financial Officer has served as our interim CEO and our Board has not appointed a Chairman of the Board. During meetings of our Board of Directors, Mr. Johnson, an independent director, acts as Chairman of the Board.

10

Our independent directors meet in executive sessions without management present to evaluate whether management is performing its responsibilities in a manner consistent with the direction of the Board. Additionally, all Board committee members are independent directors. The committee chairs have authority to hold executive sessions without management present. The Board has determined that its current structure is in the best interests of the Company and its stockholders. We believe the independent nature of the Audit Committee and the Compensation Committee as well as the practice of regular meetings of the independent directors in executive session without Mr. Flowers present ensures that the Board maintains a level of independent oversight of management that is appropriate for the Company.

Board Risk Oversight

Our Board oversees and maintains our governance and compliance processes and procedures to promote the conduct of our business in accordance with applicable laws and regulations and with the highest standards of responsibility, ethics and integrity. As part of its oversight responsibility, our Board is responsible for the oversight of risks facing the Company and seeks to provide guidance with respect to the management and mitigation of those risks. Our board also delegates specific areas of risk to the Audit Committee which is responsible for the oversight of risk policies and processes relating to our financial statements and financial reporting processes. The Audit Committee reviews and discusses with management and the independent auditors significant risks and exposures to the Company and steps management has taken or plans to take to minimize or manage such risks. The Audit Committee meets with our Chief Financial Officer and our independent auditor at each regular meeting of the Audit Committee.

Director Legal Proceedings

During the past ten years, no director, executive officer or nominee for our Board of Directors has been involved in any legal proceedings that are material to an evaluation of their ability or integrity to become our director or executive officer.

Related Party Transactions

We have not entered into any transaction during fiscal year ended May 31, 2017 in which any related person, as defined in Item 404 of Regulation S-K, had or will have a direct or indirect material interest.

We have established policies and other procedures regarding approval of transactions between the Company and any employee, officer, director, and certain of their family members and other related persons, including those required to be reported under Item 404 of Regulation S-K. These policies and procedures are generally not in writing, but are evidenced by long standing principles set forth in our Code of Ethics or adhered to by our Board. As set forth in the Audit Committee Charter, as and to the extent required under applicable federal securities laws and related rules and regulations, and/or the NASDAQ Rules, related party transactions are to be reviewed and approved, if appropriate, by the Audit Committee. Generally speaking, we enter into such transactions only on terms that we believe are at least as favorable to the Company as those that we could obtain from an unrelated third party.

Code of Ethics

We have adopted a Code of Ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our Code of Ethics is available on our website at www.ptsc.com under the link “Investors” and “Management Team”.

Communicating with the Board of Directors

We have established a hotline for the confidential, anonymous submission by our directors, officers and employees of concerns regarding violations or suspected violations of our ethics policy including matters relating to accounting and auditing. In addition, the Audit Committee has established procedures for the receipt, retention and treatment of communications received by us, our Board of Directors and the Audit Committee regarding accounting, internal controls or auditing matters. Written communications from our stockholders and employees may be sent to: Patriot Scientific Corporation, Attention: Audit Committee Chair, 2038 Corte Del Nogal, Suite 141, Carlsbad, California 92011-1478.

In addition, our annual meeting of stockholders provides an opportunity each year for stockholders to ask questions of or otherwise communicate directly with members of the Board on appropriate matters. In addition, stockholders may communicate in writing with any particular director, or the directors as a group, by sending such written communication to: Board of Directors, Attention: Corporate Secretary, Patriot Scientific Corporation, 2038 Corte Del Nogal, Suite 141, Carlsbad, California 92011-1478. Copies of written communications received at such address will be provided to the Board or the relevant director unless such communications are considered, in the reasonable judgment of the Secretary, to be inappropriate for submission to the intended recipient(s). Examples of stockholder communications that would be considered inappropriate for submission to the Board include, without limitation, customer complaints, solicitations, communications that do not relate directly or indirectly to our business or communications that relate to improper or irrelevant topics.

Director Attendance at Annual Meetings of Stockholders

We have no policy requiring directors to attend annual meetings of stockholders, but directors are encouraged to attend our annual meetings at which they stand for re-election. All of the directors attended the 2016 Annual Meeting of Stockholders.

PROPOSAL NUMBER 2

RATIFICATION OF THE APPOINTMENT OF KMJ CORBIN & COMPANY LLP

The next proposal on the agenda for the annual meeting will be ratifying the Board’s appointment of KMJ Corbin & Company LLP as our independent registered public accounting firm for current fiscal year ending May 31, 2018. The Audit Committee of the Board has appointed KMJ Corbin & Company LLP, certified public accountants to serve as our independent registered public accounting firm for the fiscal year ending May 31, 2018. Our stockholders are being requested to ratify the appointment. KMJ Corbin & Company LLP has served as our independent auditors and accountants since November 23, 2005. Since November 23, 2005, there were no disagreements between us and KMJ Corbin & Company LLP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure. The Audit Committee recommended to the Board that KMJ Corbin & Company LLP be re-appointed for fiscal year 2018. A representative of KMJ Corbin & Company LLP will be available at the annual meeting. They will have the opportunity to make a statement if they desire to do so, and they are expected to be available to respond to appropriate questions.

Stockholder ratification of the selection of KMJ Corbin & Company LLP as our independent auditors is not required by the Bylaws or otherwise. However, the Board is submitting the selection of KMJ Corbin & Company to the stockholders LLP for ratification as a matter of corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of us and our stockholders.

Vote Required; Board Recommendation

The Board recommends a vote in favor of this proposal. The affirmative vote of a majority of the votes cast will be required to approve this proposal.

Independent Registered Public Accounting Firm Fees

The following summarizes aggregate fees billed to us for the fiscal years ended May 31, 2017 and 2016 by KMJ Corbin & Company LLP, our independent registered public accounting firm:

	2017		2016
Audit fees	$	64,350	$	75,350
Tax fees		8,500		11,661
Total fees	$	72,850	$	87,011

13

Audit fees pertain to the audit of our annual consolidated financial statements for fiscal years 2017 and 2016, and timely reviews of our quarterly consolidated financial statements, consents, comfort letters, and review of documents filed with the SEC.

Tax fees relate to tax compliance services rendered in the preparation of our tax returns.

Pre-Approval Policy for Services Provided by our Independent Registered Public Accounting Firm

Pursuant to the Policy on Engagement of Independent Auditor, the Audit Committee is directly responsible for the appointment, compensation and oversight of the independent auditor. The Audit Committee pre-approves all audit services and non-audit services to be provided by the independent auditor and has approved 100% of the audit, audit-related and tax fees. The Audit Committee may delegate to one or more of its members the authority to grant the required approvals, provided that any exercise of such authority is presented at the next Audit Committee meeting for ratification.

Each audit, non-audit and tax service that is approved by the Audit Committee will be reflected in a written engagement letter or writing specifying the services to be performed and the cost of such services, which will be signed by either a member of the Audit Committee or by one of our officers authorized by the Audit Committee to sign on our behalf.

The Audit Committee will not approve any prohibited non-audit service or any non-audit service that individually or in the aggregate may impair, in the Audit Committee’s opinion, the independence of the independent auditor.

In addition, since January 1, 2003, our independent auditor may not provide any services to our officers or Audit Committee members, including financial counseling or tax services.

Report of the Audit Committee of the Board of Directors (*)

Each year, the Board of Directors appoints an Audit Committee to review the Company’s financial matters. We operate pursuant to a written Audit Committee Charter adopted by the Board of Directors. In accordance with the Audit Committee Charter, we must meet the independence requirements and other criteria set by the NASDAQ Marketplace Rules as currently in effect. As part of our oversight of the Company’s financial statements, our Chair of the Audit Committee reviews and discusses with both management and KMJ Corbin & Company LLP all annual and quarterly financial statements prior to their issuance. In addition, our responsibilities include recommending to the Board an accounting firm to be hired as the Company’s independent registered public accounting firm. We are also responsible for recommending to the Board that the Company’s financial statements be included in its Annual Report. We have taken the following steps in making our recommendation that the Company’s financial statements be included in its Annual Report:

1. The Audit Committee discussed with KMJ Corbin & Company LLP, the Company’s independent registered public accounting firm, for fiscal year ended May 31, 2017, those matters required to be discussed by Statement on Auditing Standards No. 61, including information regarding the scope and results of the audit. These communications and discussions are intended to assist the Audit Committee in overseeing the financial reporting and disclosure process.

2. The Audit Committee discussed with KMJ Corbin & Company LLP, its independence and received from KMJ Corbin & Company LLP a letter concerning independence as required under applicable independence standards for auditors of public companies. This discussion and disclosure helped the Audit Committee in evaluating such independence.

3. The Audit Committee reviewed and discussed with the Company’s management and KMJ Corbin & Company LLP, the Company’s audited consolidated balance sheet at May 31, 2017, and consolidated statements of operations, cash flows and stockholders’ equity for the fiscal year ended May 31, 2017.

Based on the reviews and discussions explained above, the Audit Committee recommended to the Board that the Company’s financial statements be included in its annual report for its fiscal year ended May 31, 2017. The Audit Committee also recommended to the Board the selection of KMJ Corbin & Company LLP to serve as the Company’s independent registered public accounting firm for fiscal year 2018.

THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

Gloria H. Felcyn, Chair of the Audit Committee

Carlton M. Johnson, Jr.

*  The report of the Audit Committee shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such Acts.

PROPOSAL NUMBER 3

Pursuant to Section 14A of the Exchange Act, we are seeking our stockholders’ approval, on an advisory basis, of the compensation of our named executive officers as disclosed pursuant to the SEC’s compensation disclosure rules (which disclosure includes the related compensation tables on pages 14 and 15 in this Proxy Statement). This advisory vote is commonly referred to as a “say-on-pay” proposal. Our stockholders previously voted that the frequency of the “say-on-pay” vote will be annually.. At the Annual Meeting of the Stockholders held in 2013, a majority of votes cast by stockholders present and entitled to vote on the proposal selected one year as the desired frequency of future stockholder say-on-pay votes with respect to the say-on-frequency proposal. As such, the Board adopted a resolution to hold “say-on-pay” votes annually. The stockholders will be asked to vote again on the say-on-frequency proposal at the Annual Meeting of the Stockholders held in 2019.

The Compensation Committee, which is responsible for designing and administering our executive compensation program, has designed our executive compensation program to provide a competitive and internally equitable compensation and benefits package that reflects the Company performance, job complexity, and strategic value of the position while seeking to ensure the individual’s long-term retention and motivation and alignment with the long-term interests of our stockholders. We are asking our stockholders to indicate their support for our named executive officers compensation as described in this proxy statement. This vote is not intended to address any specific item of compensation, but rather the overall fiscal year 2017 compensation of our named executive officers described in this proxy statement. Accordingly, we are asking our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that our stockholders approve, on an advisory basis, the compensation of the Named Executive Officers, as disclosed in our proxy statement for the 2017 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC.”

Vote Required; Board Recommendation

Adoption of this resolution will require the affirmative vote of the majority of the shares of common stock represented in person or by proxy at the meeting. Abstentions will not be counted as either votes cast for or against the Proposal.

The results of this advisory vote are not binding upon us. However, the Compensation Committee values the opinions expressed by stockholders in their vote, and will consider the outcome of the vote in deciding whether any actions are necessary to address concerns raised by the vote and when making future compensation decisions for named executive officers.

The Board of Directors unanimously recommends that stockholders vote for the advisory proposal on executive compensation.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS, DIRECTORS AND MANAGEMENT

The following table sets forth, as of April 2, 2018, the stock ownership of our executive officer and directors, of our executive officer and directors as a group, and of each person known to us to be a beneficial owner of 5% or more of our Common Stock. In general, “Beneficial Ownership” refers to shares that an individual or entity has the power to vote or dispose of, and any rights to acquire common stock that are currently exercisable or will become exercisable within 60 days of April 2, 2018. The number of shares of Common Stock outstanding as of April 2, 2018, was 401,392,948. Except as otherwise noted, each person listed below is the sole beneficial owner of the shares and has sole investment and voting power over such shares. Each individual’s address is 2038 Corte Del Nogal, Suite 141, Carlsbad, California 92011-1478.

(4) Includes 2,300,000 shares issuable upon the exercise of outstanding stock options exercisable within 60 days of April 2, 2018.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who beneficially own 10% or more of a class of securities registered under Section 12 of the Exchange Act to file reports of beneficial ownership and changes in beneficial ownership with the SEC. Directors, executive officers and greater than 10% stockholders are required by the rules and regulations of the SEC to furnish us with copies of all reports filed by them in compliance with Section 16(a).

Based solely on our review of the copies of such forms received by us, or written representations from reporting persons, we believe that our insiders complied with all applicable Section 16(a) filing requirements during fiscal year 2017.

Employment Contracts

In connection with Mr. Flowers’ appointment as Chief Financial Officer on September 17, 2007, we entered into an Employment Agreement (the “Flowers Agreement”) with Mr. Flowers for an initial 120-day term if not terminated pursuant to the Flowers Agreement, with an extension period of one year and on a day-to-day basis thereafter. On December 30, 2016, we entered into an amended and restated Employment Agreement (the “Amended and Restated Employment Agreement”) with Mr. Flowers. Pursuant to the Flowers Agreement, Mr. Flowers’ initial base salary was $225,000 per year and he is eligible to receive an annual merit bonus of up to 50% of his base salary, as determined in the sole discretion of the Board of Directors. Effective October 1, 2008, October 5, 2009 and December 15, 2011, Mr. Flowers’ base salary was increased to $231,750, $291,750 and $327,750, respectively. Also pursuant to the Flowers Agreement and on the date of the Flowers Agreement, Mr. Flowers received a fully vested grant of non-qualified stock options to purchase 150,000 shares of our Common Stock and a grant of non-qualified stock options to purchase 600,000 shares of our Common Stock vesting over four years. Mr. Flowers’ right to exercise the foregoing stock options became fully vested on October 9, 2009, in connection with his appointment as Interim CEO. The Flowers Agreement also provides for Mr. Flowers to receive customary employee benefits, including health, life and disability insurance.

Pursuant to the Amended and Restated Employment Agreement, if Mr. Flowers is terminated without cause or resigns with good reason any time after two years of continuous employment, he is entitled to receive an amount equal to 1.25 times his annual base salary. Mr. Flowers is also entitled to certain payments upon a change of control of the Company if the surviving corporation does not retain him. All such payments are conditional upon the execution of a general release.
