The availability of internet voting will depend on the voting process of your bank, broker or other nominee. Please check with your bank, broker or other nominee and follow the voting instructions it provides.

TABLE OF CONTENTS

What is a proxy?

A proxy is a person you appoint to vote on your behalf. By using the methods discussed above, you will be appointing Colin James Deller, our Chief Executive Officer, and/or Brian G. Fike, our Chief Financial Officer, Treasurer and Secretary, as your proxies. They may act together or individually to vote on your behalf, and will have the authority to appoint a substitute to act as proxy. If you are unable to attend the Annual Meeting, please vote by proxy so that your shares of common stock may be counted.

How will my proxy vote my shares?

If you are a shareholder of record, your proxy will vote according to your instructions. If you choose to vote by mail and complete and return the enclosed proxy card but do not indicate your vote, your proxy will vote “FOR” the election of the director-nominees (see Proposal 1), “FOR” the approval, on an advisory basis, of Gumbiner Savett Inc. as our independent registered public accounting firm for the year ending December 31, 2020 (see Proposal 2), “FOR” approving, on an advisory basis, of the compensation paid to our named executive officers (see Proposal 3) and “FOR” approving one or more adjournments of the Annual Meeting to a later date or dates to solicit additional proxies in the absence of a quorum (see Proposal 4).

We do not intend to bring any other matter for a vote at the Annual Meeting, and we do not know of anyone else who intends to do so, however, we will transact any such other business as may properly come before the Annual Meeting or any adjournments thereof. Your proxies are authorized to vote on your behalf, using their best judgment, on any other business that properly comes before the Annual Meeting.

If your shares are held in the name of a bank, broker or other nominee (a “Nominee”), you will receive separate voting instructions from your Nominee describing how to vote your shares. The availability of internet voting will depend on the voting process of your Nominee. Please check with your Nominee and follow the voting instructions your Nominee provides.

You should instruct your Nominee how to vote your shares. If you do not give voting instructions to the Nominee, the Nominee will determine if it has the discretionary authority to vote on the particular matter. Under applicable rules, brokers have the discretion to vote on routine matters, such as the ratification of the selection of an independent registered public accounting firm, but do not have discretion to vote on non-routine matters. Under the regulations applicable to New York Stock Exchange member brokerage firms (many of whom are the record holders of shares of our common stock), the uncontested election of directors is no longer considered a routine matter. Matters related to executive compensation and to the implementation of, or a material revision to, an equity incentive plan are also not considered routine matters. As a result, if you are a beneficial owner and hold your shares in street name, but do not give your Nominee instructions on how to vote your shares with respect to Proposals 1 and 3, votes may not be cast on your behalf. If your Nominee indicates on its proxy card that it does not have discretionary authority to vote on a particular proposal, your shares will be considered to be “broker non-votes” with regard to that matter. Broker non-votes will be counted as present for purposes of determining whether enough votes are present to hold our Annual Meeting, but a broker non-vote will not otherwise affect the outcome of a vote.

How do I change my vote?

If you are a shareholder of record, you may revoke your proxy at any time before your shares are voted at the Annual Meeting by:

•

notifying our Chief Financial Officer, Treasurer and Secretary, Brian G. Fike, by e-mail to brian.fike@clearsign.com that you are revoking your proxy;

•

submitting a proxy at a later date via the internet or telephone or by signing and delivering a proxy card relating to the same shares and bearing a later date than the date of the previous proxy prior to the vote at the Annual Meeting, in which case your later-submitted proxy will be recorded, and your earlier proxy revoked; or

•

attending and voting at the Annual Meeting.

TABLE OF CONTENTS

If your shares are held in the name of a Nominee, you should check with your Nominee and follow the voting instructions provided by your Nominee.

Who will count the votes?

Our Secretary, Brian G. Fike, will act as the inspector of election and count the votes, with the assistance of reports provided by Broadridge Shareholder Services.

What constitutes a quorum?

The holders of a majority of the Company’s eligible votes as of the Record Date, either present or represented by proxy, constitute a quorum. A quorum is necessary in order to conduct the Annual Meeting. If you choose to have your shares represented by proxy at the Annual Meeting, you will be considered part of the quorum. Both abstentions and broker non-votes are counted as present for the purpose of determining the presence of a quorum. If a quorum is not present at the Annual Meeting, the shareholders present in person or by proxy may adjourn the meeting to a later date. If an adjournment is for more than 30 days or a new record date is fixed for the adjourned meeting, we will provide notice of the adjourned meeting to each shareholder of record entitled to vote at the meeting.

What vote is required to approve each proposal?

Election of Directors. For Proposal 1, the election of directors, the nominees will be elected by a plurality of the votes of the shares of common stock present in person or represented by proxy and entitled to vote at the Annual Meeting. You may choose to vote, or withhold your vote, separately for each nominee. A properly executed proxy with voting instructions marked “WITHHOLD” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for the purposes of determining whether there is a quorum.

Approval, on an Advisory Basis, of the Appointment of Gumbiner Savett Inc. as the Company’s Independent Registered Public Accounting Firm. This is an advisory vote only and not binding on the Company. The Audit Committee will consider the outcome of this vote when making future decisions regarding the appointment of an independent registered public accounting firm.

Approval, on an Advisory Basis, of the Compensation Paid to our Named Executive Officers. Proposal 3 is also an advisory vote only. This vote will not be binding on us, our Board, or our Compensation Committee. However, the Board and the Compensation Committee will consider the outcome of this vote when making future compensation decisions for our executive officers.

Other Proposals. So long as a quorum is present, in order to approve any other proposal that might properly come before the Annual Meeting, the affirmative vote of the holders of shares of common stock entitled to vote must exceed the votes cast against the proposal, except when a different vote is required by law or by our articles of incorporation or bylaws.

Abstentions and broker non-votes with respect to any matter will be counted as present and entitled to vote on that matter for purposes of establishing a quorum, but will not be counted for purposes of determining the number of votes cast. Accordingly, abstentions and broker non-votes will have no effect on the outcome of voting with respect to any of the proposals.

What percentage of the Company’s common stock do our directors and officers own?

As of April 24, 2020, our current directors and executive officers beneficially owned approximately 25.6% of our common stock outstanding. See the discussion under the heading “Security Ownership of Certain Beneficial Owners and Management” on page 22 for more details.

Who is soliciting proxies, how are they being solicited, and who pays the cost?

We, on behalf of our Board, through our directors, officers, and employees, are soliciting proxies primarily by mail. Proxies may also be solicited in person, by telephone, by facsimile or by other methods of communication. We will pay the cost of soliciting proxies. We will also reimburse stockbrokers and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to the owners of our common stock.

TABLE OF CONTENTS

We do not plan to employ a professional solicitation firm with respect to proposals to be presented at the Annual Meeting. However if, for example, we do not believe we will meet the quorum requirements for shareholder meetings set forth in our bylaws, we may retain a proxy solicitation firm to solicit proxies. If we do so, we will pay a fee for those services and will reimburse the proxy solicitation firm for payments made to brokers and other nominee holders for their expenses in forwarding soliciting material. We may also agree that the proxy solicitation firm’s fees may increase if certain changes in the scope of its services occur.

Who is the independent registered public accounting firm, and will they be represented at the Annual Meeting?

Gumbiner Savett Inc. served as the independent registered public accounting firm auditing and reporting on our consolidated financial statements for the year ended December 31, 2019 and has been appointed to serve as our independent registered public accounting firm for 2020. We expect that representatives of Gumbiner Savett Inc. will not be present at the Annual Meeting.

What are the recommendations of the Board?

The recommendations of our Board are set forth together with the description of each proposal in this proxy statement. In summary, the Board recommends a vote:

•

FOR the election of the director nominees (see Proposal 1);

•

FOR the approval of Gumbiner Savett Inc. as our independent registered public accounting firm for the year ending December 31, 2020 (see Proposal 2);

•

FOR the approval of the compensation paid to our named executive officers (see Proposal 3); and

•

FOR the approval of one or more adjournments of the Annual Meeting to a later date or dates to solicit additional proxies in the absence of a quorum (see Proposal 4).

With respect to any other matter that properly comes before the meeting, the proxy holders will vote as recommended by the Board or, if no recommendation is given, in their own discretion.

If you sign and return your proxy card but do not specify how you want to vote your shares, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of the Board.

TABLE OF CONTENTS

GOVERNANCE OF THE COMPANY

The following table sets forth the names and ages of the directors and executive officers serving immediately prior to the Annual Meeting. Our officers are appointed by, and serve at the pleasure of, the Board.

Name	Age	Position
Colin James Deller	52	Chief Executive Officer and Director
Brian G. Fike	51	Chief Financial Officer, Treasurer and Secretary
Robert T. Hoffman Sr.	61	Director
Lon E. Bell, Ph.D.*	79	Director
Susanne L. Meline	52	Director
Bruce A. Pate	62	Director

Dr. Bell notified us on April 15, 2020 that he would not stand for re-election, therefore his term will expire on the date of the Annual Meeting.

Our business, property and affairs are managed by, or under the direction of, our Board, in accordance with the Washington Business Corporation Act and our bylaws. Members of the Board are kept informed of our business through discussions with the Chief Executive Officer and other key members of management, by reviewing materials provided to them by management, and by participating in meetings of the Board and its Committees.

Shareholders may communicate with the members of the Board, either individually or collectively, or with any independent directors, individually or as a group, by writing to the Board at 12870 Interurban Avenue South, Seattle, Washington 98168. These communications will be reviewed by the Secretary who, depending on the subject matter, will (a) forward the communication to the director or directors to whom it is addressed or who is responsible for the topic matter, (b) attempt to address the inquiry directly (for example, where it is a request for publicly available information or a stock related matter that does not require the attention of a director), or (c) not forward the communication if it is primarily commercial in nature or if it relates to an improper or irrelevant topic. At each meeting of the Nominating and Corporate Governance Committee, the Secretary presents a summary of communications received but not forwarded in accordance with subsection (a) and will make those communications available to any director upon request.

Independence of Directors

In determining the independence of our directors, we apply the definition of “independent director” provided under the listing rules of The Nasdaq Stock Market LLC (“Nasdaq”). Pursuant to these rules, the Board concluded its annual review of director independence in February 2020. After considering all relevant facts and circumstances, the Board affirmatively determined that all of the directors then serving on the Board, including those nominated for election at the Annual Meeting, are independent within the meaning of Nasdaq Listing Rule 5605(a)(2) and Rule 10A-3(b) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with the exception of Robert T. Hoffman Sr. and Colin James Deller.

Board Meetings and Committees of our Board

The Board has three standing committees, the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee, referred to in this proxy statement as the “Governance Committee” (collectively, the “Board Committees”). Immediately prior to the Annual Meeting, our independent directors, Ms. Meline, Dr. Bell and Mr. Pate, were members of each of the Board Committees. On April 15, 2020, Dr. Bell informed the Board that he would not stand for re-election, therefore, the current members of the Board Committees are Ms. Meline and Mr. Pate. Ms. Meline is the Chairperson of the Audit Committee and the Board has determined that she, together with Mr. Pate, are audit committee financial experts. Mr. Pate is the Chairperson of the Compensation Committee and the Governance

TABLE OF CONTENTS

Committee. During the year ended December 31, 2019, the Board held ten meetings, the Audit Committee held six meetings, the Compensation Committee held four meetings, and the Governance Committee held four meetings. Each of our directors attended at least 75% of the meetings held by the Board and the Board Committees of which he or she is a member. We do not have a policy with regard to Board attendance at the Annual Meeting. All of the members of our Board attended the 2019 Annual Meeting.

The Compensation Committee has sole authority to retain and terminate any compensation expert or consultant used to provide advice on compensation levels or assist in the evaluation of director, Chief Executive Officer or senior executive compensation, including sole authority to approve the fees of any expert or consultant and other retention terms. In addition, the Compensation Committee considers, but is not bound by, the recommendations of our Chief Executive Officer with respect to the compensation packages of our other executive officers.

A copy of the charter of the Governance Committee is available on our website at www.clearsign.com (under “Investors-Corporate Governance-Governance Documents”). The members of the Governance Committee reviewed the qualifications of the director-nominees.

Policy with Regard to Security Holder Proposals and Director Recommendations

Shareholder proposals are reviewed by the Secretary for compliance with the requirements for such proposals, which are set forth in our Policy Regarding Shareholder Candidates for Nomination (the “Policy”) and in Regulation 14a-8 of the Exchange Act. Shareholder proposals that meet these requirements will be summarized by the Secretary. Summaries and copies of the shareholder proposals are circulated to the Chairman of the Governance Committee.

The Governance Committee will consider director candidates recommended by shareholders. If a director candidate is recommended by a shareholder (a “Nominating Shareholder”), the Governance Committee expects to evaluate such candidate in the same manner it evaluates director candidates it identifies. The Policy requires a Nominating Shareholder to have continuously held at least 5% of the Company’s common stock for at least three years by the date the name of the candidate is submitted, and to continue to hold the common stock through the date of the annual meeting. The Policy permits a Nominating Shareholder to submit one candidate for consideration at any annual meeting of shareholders. Pursuant to the Policy, a Nominating Shareholder must submit a candidate for consideration as a director in writing to the Company’s Secretary; the submission must be received by a date not later than the 120th calendar day before the anniversary of the date that the prior year’s annual meeting proxy statement was released to shareholders (or if the annual meeting date has changed by more than 30 days, a reasonable time before we begin to print and mail the proxy statement) and must include the following information:

The name, address and number of shares of common stock owned by the Nominating Shareholder;

A representation that the Nominating Shareholder meets the requirements described above and will continue to meet them through the date of the annual meeting. If the Nominating Shareholder is not a registered holder of the Company’s common stock, the Nominating Shareholder must provide evidence of eligibility as provided in Exchange Act Rule 14a-8(b)(2).

TABLE OF CONTENTS

A description of all arrangements or understandings (whether written or oral) between or among the Nominating Shareholder and the candidate or any other person or entity (naming such person or entity) regarding the candidate’s nomination.

All information regarding the candidate that the Company would be required to disclose in a proxy statement filed pursuant to the rules and regulations of the Securities and Exchange Commission with respect to a meeting at which the candidate would stand for election.

Confirmation that the candidate is independent under the independence requirements established by the Company, Rule 10A-3(b) promulgated under the Exchange Act and Nasdaq Listing Rule 5605(a)(2), or if the candidate is not independent under all such criteria, a description of the reasons why the candidate is not independent.

The consent of the candidate to serve as a member of the Company’s board of directors, if nominated and elected.

A representation signed by the candidate that if elected he or she will:

(i)

represent all shareholders of the Company in accordance with applicable laws and the Company’s article of incorporation, bylaws and other policies;

(ii)

comply with all rules, policies or requirements generally applicable to non-executive directors; and

(iii)

upon request, complete and sign a customary director and officer questionnaire.

Our Policy Regarding Shareholder Candidates for Nomination is available on our website at www.clearsign.com (under “Investors-Corporate Governance-Governance Documents”).

Director Qualifications and Diversity

The Board seeks independent directors who represent a diversity of backgrounds and experiences that will enhance the quality of the Board’s deliberations and decisions. Candidates should preferably have board experience with one or more companies or should have achieved a high level of distinction in their chosen fields. The Board is particularly interested in maintaining a mix that includes individuals who are active or retired executive officers and senior executives, particularly those with experience in combustion, technology, air pollution control and air emission regulation, intellectual property, start-up companies, research and development, strategic planning, business development, compensation, finance, accounting and banking.

In evaluating nominations to the Board, the Governance Committee also looks for certain personal attributes, such as integrity, ability and willingness to apply sound and independent business judgment, comprehensive understanding of a director’s role in corporate governance, availability for meetings and consultation on Company matters, and the willingness to assume and carry out fiduciary responsibilities. The Governance Committee took these specifications into account in formulating and re-nominating its present Board members. The current director candidates were recommended by the Governance Committee, which is comprised of only independent directors.

Compensation Committee Interlocks and Insider Participation

None of our prior or current executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board or the Compensation Committee.

Code of Ethics

We adopted a Code of Business Conduct and Ethics (“Code of Ethics”) applicable to our principal executive officer and principal financial and accounting officer and any persons performing similar functions. In addition, the Code of Ethics applies to our employees, officers, directors, agents and representatives. The Code of Ethics requires, among other things, that our employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical

TABLE OF CONTENTS

manner, and otherwise act with integrity and in our best interest. The Code of Ethics is available on our website at www.clearsign.com (under “Investors-Corporate Governance-Governance Documents”). We intend to satisfy the disclosure requirement regarding an amendment to, or a waiver from, a provision of our Code of Ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions by posting the information on our internet website, www.clearsign.com.

Risk Oversight by the Board of Directors

It is management’s responsibility to assess and manage the various risks we face. It is the Board’s responsibility to oversee management in this effort, in order to ensure that risks and uncertainties that may relate to our ongoing operations and to our plans for the future are considered and managed appropriately. In exercising its oversight, the Board has allocated some areas of focus to its Committees and has retained areas of focus for itself, as more fully described below.

Full Board — Risks and exposures focused on by the full Board include strategic, financial and execution risks including cyber and safety risks, and other current matters that may present material risks to our operations, plans, prospects or reputation. Throughout the year, the Chief Executive Officer discusses these risks with the Board during strategy reviews that focus on a particular function or aspect of our business.

Audit Committee — Risks and exposures focused on by the Audit Committee are those associated with financial matters, particularly financial reporting, tax, accounting, disclosure, internal control over financial reporting, financial policies, investment guidelines, risk management as a whole and credit and liquidity matters.

Governance Committee — Risks and exposures focused on by the Governance Committee are those relating to corporate governance and management and director succession planning.

Compensation Committee — Risks and exposures focused on by the Compensation Committee are those associated with leadership assessment and compensation programs and arrangements, including incentive plans, to ensure that compensation incentives are aligned with our risk management objectives.

Board Leadership Structure

The Chairperson of the Board presides at all meetings of the Board. The Chairperson is appointed on an annual basis by a majority vote of the directors. At a special meeting of the Board held on November 6, 2018, the Board determined to separate the offices of the Chief Executive Officer and the Chairperson. The Board believes that this leadership structure increases the Board’s independence from management by allocating authority for operational leadership to the Chief Executive Officer while allocating to the Board the responsibility for monitoring and overseeing management. The Board again appointed Ms. Meline to the role of lead independent director at a meeting held on February 13, 2020. As the lead independent director, Ms. Meline is the liaison between Mr. Hoffman, as the Chairperson, and the other independent directors. We believe that having a lead independent director will facilitate communication among the members of the Board.

Delinquent Section 16(a) Reports

Based solely upon a review of Forms 3, 4 and 5 furnished to the Company, the Company believes that, with the exception of the individuals named below, all of its directors, officers and beneficial owners of more than 10% of our equity securities timely filed these reports during 2019.

Donald Kendrick, our Chief Technology Officer, and Stephen Sock, our Senior Vice President of Business Development, each filed a Form 4 reporting the grant of an option one day after the filing due date.

Robert T. Hoffman, Lon E. Bell, Susanne Meline, Bruce Pate and James Simmons, a former director, each filed a timely Form 4 reporting option grants made on May 9, 2019. The options were granted as compensation for the director services provided to the Company by each individual. However, the Form 4s reported only that portion of the options that vested as of the grant date, rather than reporting the entire grant. These individuals continued reporting the options as they vested until October 31, 2019 when the Form 4s were amended to report the entire option grant.

PROPOSAL 1 — ELECTION OF DIRECTORS

Nominees for Election

As of the date of the Annual Meeting, the Board of Directors will be comprised of four members. Our Board, upon the recommendation of the Governance Committee, has nominated our four incumbent directors for re-election at the Annual Meeting. Each nominee has agreed, if elected, to serve until the election and qualification of his or her successor. If any nominee is unable to stand for election, which circumstance we do not anticipate, the Board may provide for a lesser number of directors or designate a substitute. In the latter event, shares represented by proxies may be voted for a substitute nominee.

If a quorum is present at the Annual Meeting, then nominees will be elected by a plurality of the votes cast. There is no cumulative voting in the election of directors.

The following biographical information is furnished as to each nominee for election as a director:

Robert T. Hoffman Sr.

Mr. Hoffman became a director of our Company in July 2018 in conjunction with the execution of a Voting Agreement between the Company and clirSPV LLC and was appointed as Chairman in November 2018.

Mr. Hoffman also was a Managing Director and Portfolio Manager for the Growth & Income (G&I) mutual fund and institutional assets of what was originally Scudder Stevens and Clark, where he was responsible for all buy and sell decisions. During his tenure, G&I assets under management expanded from approximately $1.75 billion to more than $25 billion. Mr. Hoffman was also nominated by two separate governors to serve three terms as a Member and Chairman of the State of New Jersey Investment Council (SIC) from 1990 to 2002. The SIC has ultimate oversight responsibility for state and local pension funds totaling more than $80 billion. Mr. Hoffman’s career also includes service as the Assistant State Treasurer for Pensions and Investments for the State of New Jersey, Special Assistant to the Governor of New Jersey and Mergers, and Acquisitions Analyst at ABN/LaSalle Bank. He holds an M.B.A. with Distinction from the Kellogg School of Management at Northwestern University and an Economics degree from Dartmouth College.

Susanne L. Meline

Ms. Meline has been a director of our Company since February 2018. In 2003, Ms. Meline co-founded Francis Capital Management (“FCM”), a value-based investment advisor, where she continues to specialize in analyzing small cap stocks. Prior to co-founding FCM, Ms. Meline worked as an investment banker with Houlihan Lokey, a global investment bank serving corporations, institutions, and governments worldwide. She also practiced law in the corporate group of Jones Day, an international law firm that provides legal advisory services across multiple disciplines and jurisdictions.

TABLE OF CONTENTS

Hamworthy Combustion while also completing his Ph.D. In 1996, Dr. Deller joined Callidus, where he was employed in Project Engineering and Sales, and over the course of ten years advanced to serve as Chief Combustion Engineer and Manager of Burner Order Execution before being promoted to oversee Callidus’ entire burner business. From 2010 until he left Callidus, following the acquisition of Callidus by Honeywell, Dr. Deller served as General Manager with full profit and loss accountability for the Honeywell UOP Callidus burner business worldwide. During that time, he led his team in developing new international markets, including developing a leading market position in China. From May 2018 until he joined the Company, Dr. Deller served as the interim Global Operations Director for the entire Honeywell International UOP Callidus business, which includes flares and thermal oxidizers in addition to burners.

Dr. Deller has a Bachelor of Engineering in mechanical engineering from Portsmouth Polytechnic, U.K., a doctorate in flame chemistry from the University of Portsmouth, U.K., and an MBA from The University of London.

The investment experience that each of Ms. Meline and Messrs. Hoffman and Pate brings to our Board includes their experience in analyzing the operations of businesses, and particularly smaller capitalized companies, to determine the likelihood of success. In addition, Ms. Meline has significant experience with respect to best practices in corporate governance. We believe that their experience, together with the expertise brought to our operations by Dr. Deller, will help us achieve our goals of proving commercial viability of our products, generating interest from end users and original equipment manufacturers and licensing our technology. For these reasons we concluded that each of these individuals should serve as a director.

None of our director nominees is related to any other director nominee or any officer. None of our director nominees has been involved in a legal proceeding that requires disclosure pursuant to Item 401(f) of Regulation S-K promulgated under the Exchange Act.

Mr. Pate was selected as a director pursuant to the terms of the Cooperation Agreement we entered into with Anthony DiGiandomenico and his affiliates in January 2019.

PROPOSAL 2 — APPROVE, ON AN ADVISORY BASIS, OF THE APPOINTMENT
OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has appointed Gumbiner Savett Inc. as our independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2020. Gumbiner Savett Inc. has served as our independent registered public accounting firm since 2011.

Shareholder approval of the selection of Gumbiner Savett Inc. as our independent registered public accounting firm is advisory only and is not required by our bylaws or the Washington Business Corporation Act. The Board seeks such approval as a matter of good corporate practice. Should the shareholders fail to approve the selection of Gumbiner Savett Inc. as our independent registered public accounting firm, the Audit Committee will reconsider whether to retain that firm in the future. In making its recommendation to the Board that shareholders ratify the appointment of Gumbiner Savett Inc. as our independent registered public accounting firm for the year ending December 31, 2020, the Audit Committee considered whether Gumbiner Savett Inc.’s provision of non-audit services is compatible with maintaining its independence. The Audit Committee approved the audit fees, audit-related fees, tax fees and all other fees described below and believes such fees are compatible with the independence of Gumbiner Savett Inc.

	2019			2018
Audit Fees		$	60,500		$	57,000
Audit Related Fees			—			—
Tax Fees		$	14,912			—

Tax Fees. “Tax Fees” are the aggregate fees of Gumbiner Savett Inc. billed for professional services rendered to us for tax compliance, tax advice, and tax planning.

All Other Fees. “All Other Fees” are the aggregate fees of Gumbiner Savett Inc. attributable to customary agreed upon professional services in connection with the underwritten sale of our common stock in February 2018, filing of our Form S-3 in June 2019, and review of our proxy statements.

Pre-approval Policies and Procedures

The Audit Committee is required to review and approve in advance the retention of the independent registered public accounting firm for the performance of all audit and lawfully permitted non-audit services and the fees for such services. The required pre-approval policies and procedures were complied with during 2019 and 2018.

Gumbiner Savett Inc. Representatives at Annual Meeting

We expect that representatives of Gumbiner Savett Inc. will not be present at the Annual Meeting.

Vote Required and Recommendation

Employment Contracts and Termination of Employment and Change-in-Control Arrangements

Employment Agreement with Colin James Deller

On January 28, 2019 (the “Effective Date”), the Company and Colin James Deller entered into an employment agreement pursuant to which the Company employed Dr. Deller as its President until April 1, 2019, at which time Dr. Deller became the Company’s Chief Executive Officer. Pursuant to the agreement, the Company pays Dr. Deller an annual salary of $350,000. As an inducement to accept employment with the Company, Dr. Deller was also granted an option to purchase 400,000 shares of the Company’s common stock at an exercise price of $1.16 per share and an option to purchase 200,000 shares of the Company’s

TABLE OF CONTENTS

common stock at an exercise price of $2.25 per share. Each option has a term of 10 years and will vest as follows: the right to purchase one-third of the shares of common stock subject to the option vested on the Effective Date and the right to purchase one-third of the shares will vest on the first day of each calendar year thereafter. The Company has agreed to pay certain expenses, not to exceed the sum of $100,000, related to Dr. Deller’s move from Tulsa, Oklahoma to Seattle, Washington, including reasonable expenses related to the sale of his home in Tulsa. As a temporary adjustment for the difference in the cost of living between Tulsa and Seattle (the “Relocation Adjustment”), for a period of four years (the “Payment Period”) from the Effective Date, the Company has also agreed to pay up to $6,000 a month to Dr. Deller for expenses related to temporary housing and travel to and from Tulsa to Seattle. If Dr. Deller purchases a home in the Seattle area, the Relocation Adjustment will continue to be paid through the expiration of the Payment Period, although the Relocation Adjustment may be adjusted or terminated upon mutual agreement of Dr. Deller and the Company. The agreement may be terminated by the Company for cause, as defined in the agreement, due to Dr. Deller’s death or disability, upon 30 days’ notice to Dr. Deller or as a result of a change in control, as defined in the agreement. With the exception of a termination for cause, if Dr. Deller’s employment is terminated by the Company, aside from accrued but unpaid salary, bonus (if any) and business expenses, Dr. Deller will receive the balance of the unpaid Relocation Adjustment and 6 months of his annual salary.

Change of Control Arrangements

All of the option awards and stock awards granted to the Company’s executive officers include change-in-control arrangements whereby any unvested stock options would vest or any repurchase rights for stock grants or, if exercised prior to vesting, stock options, would terminate as a result of a change in control.

Compensation Discussion

Overview

The Compensation Committee of the Board administers our executive compensation and benefit programs. The Compensation Committee is comprised exclusively of independent directors and oversees all compensation and benefit programs and actions that affect our executive officers.

Compensation Process and Role of Management

The Compensation Committee is responsible for determining and approving all compensation for our executive officers. Pursuant to its charter, the Compensation Committee recommends to the full Board the salary, annual incentive compensation or bonus, long-term incentive compensation in the form of stock options or stock grants, and all other employment, severance and change-in-control agreements applicable to executive officers. As discussed below, our Chief Executive Officer assists the Compensation Committee in its deliberations with respect to the compensation payable to our other executive officers.

At the end of or immediately following each fiscal year, our Chief Executive Officer evaluates executive officer performance during the year, other than his own performance, and discusses the results of such evaluations with the Compensation Committee. The Chief Executive Officer assesses each executive officer’s performance during the year based upon subjective factors concerning such officer’s individual business goals and objectives, and the contributions made by the executive officer to our overall results. The Chief Executive Officer then makes specific recommendations to the Compensation Committee for adjustments to base salary and the grant of a target bonus and/or equity award, if appropriate, as part of the compensation package for each executive officer, other than himself, for the next fiscal year.

The Compensation Committee reviews the performance of the Chief Executive Officer and determines all compensation for the Chief Executive Officer. The Chief Executive Officer is not present at the time the Compensation Committee reviews his performance and discusses his compensation.

Evaluation of Compensation Practices

In 2017, the Compensation Committee engaged Willis Towers Watson to evaluate both our executive compensation program and our director compensation program. The objective was to determine the equity

TABLE OF CONTENTS

and competitiveness of our practices with those of peer companies and relevant standards promulgated by shareholder rights organizations and other relevant stakeholders. Although the study analyzed executive compensation comprehensively, there was particular focus on equity incentives for executives. The Compensation Committee integrated the results of the May 2017 study into its evaluation of executive compensation and director compensation for the years 2018 and 2019. Willis Towers Watson provided no other services to us following the evaluation. The Compensation Committee is currently reviewing compensation trends, especially at other companies that it considers to be similar, to further evaluate current compensation levels for executives and directors.

PROPOSAL 3 — APPROVE, ON AN ADVISORY BASIS, OF THE COMPENSATION
OF OUR NAMED EXECUTIVE OFFICERS (“SAY-ON-PAY”)

In recent years, good corporate governance commentators and advisors have advocated and, increasingly, governmental regulatory authorities, including the Securities and Exchange Commission, are mandating that public companies initiate procedures to ensure that shareholders have input on compensation programs for named executive officers. This is commonly known as “Say-on-Pay”.

Our Board values and encourages constructive dialogue on executive compensation and other important governance topics with our shareholders, to whom it is ultimately accountable. We urge you to read this proxy statement for additional details on the Company’s executive compensation.

Our Say-on-Pay Proposal is designed to provide our shareholders with the opportunity to consider and vote upon the compensation paid to our named executive officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K, including the compensation table and narrative discussion. Although the vote is advisory and non-binding on the Company or the Board, our Board and the Compensation Committee will review the voting results. To the extent there is any significant lack of support for the compensation of our named executive officers, we would expect to initiate procedures designed to help us better understand shareholder concerns. We ask our shareholders to approve a Say-on-Pay proposal each year.

Marking the proxy card “For” indicates support for the compensation of our named executive officers; marking the proxy card “Against” indicates lack of support for the compensation of our named executive officers. You may abstain by marking the “Abstain” box on the proxy card.

Vote Required and Recommendation

This is an advisory vote and does not require a minimum number of votes.

The Board unanimously recommends you vote “FOR” the approval of the compensation paid to our named executive officers.

PROPOSAL 4 — APPROVE ONE OR MORE ADJOURNMENTS OF THE ANNUAL MEETING TO A LATER DATE OR DATES TO SOLICIT ADDITIONAL PROXIES IN THE ABSENCE OF A QUORUM

We are asking our shareholders to approve a proposal that will allow us to adjourn the Annual Meeting to a later date or dates to solicit additional proxies if we do not have a quorum at the Annual Meeting. If our shareholders approve this proposal, we could adjourn the Annual Meeting and any reconvened session of the Annual Meeting and use the additional time to solicit additional proxies until a quorum is obtained.

Our Board believes that it is in the best interests of our Company and our shareholders to be able to adjourn the Annual Meeting to a later date or dates if necessary or appropriate for the above referenced reasons.

Vote Required and Recommendation

If a quorum is not present at the Annual Meeting, Section 2, Subsection 2.8 of our bylaws states that a majority of the votes represented may adjourn the Annual Meeting to a later date or dates to solicit additional proxies in the absence of a quorum.

The Board unanimously recommends you vote FOR the proposal allowing the Board to adjourn the Annual Meeting to a later date or dates if necessary or appropriate to solicit additional proxies in the absence of a quorum.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table shows information known to us about beneficial ownership of our common stock by:

•

each of our directors;

•

each individual identified as an NEO in the section of this report titled “Executive Compensation”;

•

all of our directors and executive officers as a group; and

•

each person known by us to beneficially own 5% or more of our common stock.

Beneficial ownership and percentage ownership are determined in accordance with the rules of the SEC. Under these rules, beneficial ownership generally includes any shares as to which the individual or entity has sole or shared voting power or investment power and includes any shares that an individual or entity has the right to acquire ownership of on or before June 23, 2020, which is 60 days from the Record Date, through the exercise of any option, warrant, conversion privilege or similar right. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of our common stock that could be issued upon the exercise of outstanding options and warrants that are exercisable on or before June 23, 2020 are considered to be outstanding. These shares, however, are not considered outstanding as of the Record Date when computing the percentage ownership of each other person.

To our knowledge, except as indicated in the footnotes to the following table and subject to state community property laws where applicable, all beneficial owners named in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them. Percentage of ownership is based on ClearSign’s shares of common stock outstanding as of the Record Date.
