ABOUT THE MEETING: QUESTIONS AND ANSWERS

What am I voting on?

At this year’s meeting, you will be asked to:

(1) Elect five directors to serve for terms of one year each or until the election and qualification of their successors;
(2) Ratify the appointment of Gumbiner Savett Inc. as our independent registered public accounting firm for the fiscal year ending December 31, 2013;

Who is entitled to vote at the Annual Meeting, and how many votes do they have?

Stockholders of record at the close of business on March 6, 2013 (the “Record Date”) may vote at the Annual Meeting. Pursuant to the rights of our stockholders contained in our charter documents each share of our common stock has one vote. There were 8,782,015 shares of common stock outstanding on March 6, 2013. From April 18, 2013 through May 2, 2013, you may inspect a list of stockholders eligible to vote. If you would like to inspect the list, please call James N. Harmon, our Chief Financial Officer and Corporate Secretary, at (206) 673-4848 to arrange a visit to our offices. In addition, the list of stockholders will be available for viewing by stockholders at the Annual Meeting.

How do I vote?

You may vote over the Internet, by telephone, by mail or in person at the Annual Meeting. Please be aware that if you vote by telephone or over the Internet, you may incur costs such as telephone and Internet access charges for which you will be responsible.

Vote by Internet.  You can vote via the Internet at www.proxyvote.com. You will need to use the control number appearing on your proxy card to vote via the Internet. You can use the Internet to transmit your voting instructions up until 11:59 p.m. Eastern Time on Wednesday, May 1, 2013. Internet voting is available 24 hours a day. If you vote via the Internet, you do not need to vote by telephone or return a proxy card.

Vote by Telephone.  You can vote by telephone by calling the toll-free telephone number 1-800-690-6903. You will need to use the control number appearing on your proxy card to vote by telephone. You may transmit your voting instructions from any touch-tone telephone up until 11:59 p.m. Eastern Time on Wednesday, May 1, 2013. Telephone voting is available 24 hours a day. If you vote by telephone, you do not need to vote over the Internet or return a proxy card.

Vote by Mail.  If you received a printed proxy card, you can vote by marking, dating and signing it, and returning it in the postage-paid envelope provided to ClearSign Combustion Corporation, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Please promptly mail your proxy card to ensure that it is received prior to the closing of the polls at the Annual Meeting.

Vote in Person at the Meeting.  If you attend the Annual Meeting and plan to vote in person, we will provide you with a ballot at the Annual Meeting. If your shares are registered directly in your name, you are considered the stockholder of record and you have the right to vote in person at the Annual Meeting. If your shares are held in the name of your broker or other nominee, you are considered the beneficial owner of shares held in street name. As a beneficial owner, if you wish to vote at the Annual Meeting, you will need to bring to the Annual Meeting a legal proxy from your broker or other nominee authorizing you to vote those shares.

If you vote by any of the methods discussed above, you will be designating Richard F. Rutkowski, our President and Chief Executive Officer and/or James N. Harmon, our Chief Financial Officer and Corporate Secretary, as your proxy(-ies). They may act together or individually on your behalf, and will have the authority to appoint a substitute to act as proxy.

Submitting a proxy will not affect your right to attend the Annual Meeting and vote in person.

TABLE OF CONTENTS

If your shares are held in the name of a bank, broker or other nominee, you will receive separate voting instructions from your bank, broker or other nominee describing how to vote your shares. 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.

Can I receive future materials via the internet?

If you vote by internet, simply follow the prompts for enrolling in electronic proxy delivery service. This will reduce the Company’s printing and postage costs in the future, as well as the number of paper documents you will receive.

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 Richard F. Rutkowski, our President and Chief Executive Officer and James N. Harmon, our Chief Financial Officer and Corporate 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 voted.

How will my proxy vote my shares?

If you are a stockholder 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 nominated slate of directors (see Proposal 1); “FOR” the ratification of Gumbiner Savett Inc. as our independent registered public accounting firm for the fiscal year ending December 31, 2013 (see Proposal 2) and “FOR” the approval of the ClearSign Combustion Corporation 2013 Consultant Stock Plan (see Proposal 3). 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. Your proxies are authorized to vote on your behalf, however, 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, you will receive separate voting instructions from your bank, broker or other nominee describing how to vote your shares. 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 your bank, broker or other nominee provides.

You should instruct your bank, broker or other nominee how to vote your shares. If you do not give voting instructions to the bank, broker or other nominee, the bank, broker or other 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 accounting firms, 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 are also not considered routine. As a result, if you are a beneficial owner and hold your shares in street name, but do not give your broker or other nominee instructions on how to vote your shares with respect to these matters, votes may not be cast on your behalf. If your bank, broker or other 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 on a proposal that requires a majority of the votes cast. With respect to a proposal that requires a favorable vote of a majority of the outstanding shares, a broker non-vote has the same effect as a vote against the proposal.

TABLE OF CONTENTS

How do I change my vote?

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

Notifying our Corporate Secretary, James N. Harmon, in writing at 12870 Interurban Avenue South, Seattle, WA 98168, that you are revoking your proxy;
Submitting a proxy at a later date via the Internet, 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 by ballot at the Annual Meeting.

If your shares are held in the name of a bank, broker or other nominee, you should check with your bank, broker or other nominee and follow the voting instructions provided by your bank, broker or other nominee.

Who will count the votes?

Our Chief Financial Officer and Corporate Secretary, James N. Harmon, will act as the inspector of election and count the votes, with the assistance of reports provided by VStock Transfer LLC, our stock transfer agent.

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 stockholders 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 stockholder 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 or 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.

Ratification of the Appointment of Independent Registered Public Accounting Firm.  For Proposal 2, the affirmative vote of the holders of shares of stock entitled to vote must exceed the votes cast against the proposal for the proposal to be approved.

Approval of the ClearSign Combustion Corporation 2013 Consultant Stock Plan.  For Proposal 3, the affirmative vote of the holders of shares of stock entitled to vote must exceed the votes cast against the proposal for the proposal to be approved.

Other Proposals.  Any other proposal that might properly come before the meeting will require the affirmative vote of the holders of shares of common stock entitled to vote to exceed the votes cast against the proposal for the proposal to be approved, except when a different vote is required by law, our certificate of incorporation or our Bylaws. On any such proposal, abstentions 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.

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.

TABLE OF CONTENTS

What percentage of our common stock do our directors and officers own?

As of March 6, 2013, our current directors and executive officers beneficially owned approximately 24.2% of our common stock outstanding. See the discussion under the heading “Security Ownership of Certain Beneficial Owners and Management” on page 20 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 and the Internet. Further, proxies may also be solicited in person, by telephone, or facsimile. 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.

Who is our 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 financial statements for the fiscal year ended December 31, 2012 and has been appointed to serve as our independent registered public accounting firm for 2013. We expect that representatives of Gumbiner Savett Inc. will not be present at the Annual Meeting.

What are the recommendations of our 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 nominated directors (see Proposal 1);
FOR the ratification of Gumbiner Savett Inc. as our independent registered public accounting firm for the fiscal year ending December 31, 2013 (see Proposal 2).
FOR the approval of the ClearSign Combustion Corporation 2013 Consultant Stock Plan (see Proposal 3).

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

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.

Stockholders may communicate with the members of the Board, either individually or collectively, or with any independent directors as a group by writing to the Board at 12870 Interurban Avenue South, Seattle, WA 98168. These communications will be reviewed by the office of the Corporate 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 Corporate Secretary presents a summary of communications received and will make those communications available to any director upon request.

Independence of Directors

The Nominating and Corporate Governance Committee operates pursuant to a charter, which can be viewed on our website at www.clearsign.com (under “Investors”). 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 2013. 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 with the exception of Richard F. Rutkowski, who is employed as our Chief Executive Officer and President, and David B. Goodson, who consults for us as our Chief Science Officer, are independent of us under NASDAQ’s rules.

Board Meetings and Committees of our Board

The Board has three standing committees which have members (Stephen E. Pirnat, Lon E. Bell, and Scott P. Isaacson) which satisfy the independence standards of the Securities Exchange Act of 1934 and NASDAQ’s rules: the Audit Committee, the Compensation Committee, and the Nominating and Corporate Governance Committee. Mr. Pirnat is Chairman of the Audit Committee, Dr. Bell is Chairman of the Compensation Committee, and Mr. Isaacson is Chairman of the Nominating and Corporate Governance Committee. During the year ended December 31, 2012, the Board held three meetings, the Audit Committee held four meetings, the Compensation Committee held three meetings, and the Nomination and Corporate Governance Committee held two meetings. Each of our directors attended at least 75% of the aggregate Board meetings and meetings of the Board committee(s) of which he is a member. We do not have a policy with regard to Board attendance at the Annual Meeting. Prior to becoming a publicly traded company, our annual meeting was conducted by written consent of our stockholders.

Audit Committee

The Audit Committee consists of three non-employee directors, all of whom are “independent” as defined under section 5605 (a)(2) of the NASDAQ Listing Rules. In addition, the Board has determined that Steven E. Pirnat, the Chairman of our Audit Committee, qualifies as an “audit committee financial expert” as defined in the rules of the Securities and Exchange Commission (SEC). The Audit Committee operates pursuant to a charter, which can be viewed on our website at www.clearsign.com (under “Investors”). The Audit Committee met four times during 2012 with all members in attendance at each meeting. The role of the Audit Committee is to:

oversee management’s preparation of our financial statements and management’s conduct of the accounting and financial reporting processes;
oversee management’s maintenance of internal controls and procedures for financial reporting;

5


 
 

TABLE OF CONTENTS

oversee our compliance with applicable legal and regulatory requirements, including without limitation, those requirements relating to financial controls and reporting;
oversee the independent auditor’s qualifications and independence;
oversee the performance of the independent auditors, including the annual independent audit of our financial statements;
prepare the report required by the rules of the SEC to be included in our Proxy Statement; and
discharge such duties and responsibilities as may be required of the Committee by the provisions of applicable law, rule or regulation.

Compensation Committee

The Compensation Committee consists of three non-employee directors, all of whom are “independent” as defined in section 5605(a)(2) of the NASDAQ Listing Rules. The Compensation Committee met three times during 2012 with all members in attendance at each meeting. The role of the Compensation Committee is to:

develop and recommend to the Board the annual compensation (base salary, bonus, stock options and other benefits) for our President/Chief Executive Officer;
review, approve and recommend to the Board the annual compensation (base salary, bonus and other benefits) for all of our executives;
review, approve and recommend to the Board the aggregate number of equity awards to be granted to employees below the executive level;
ensure that a significant portion of executive compensation is reasonably related to the long-term interest of our stockholders; and
prepare certain portions of our annual Proxy Statement, including an annual report on executive compensation.

A copy of the charter of the Compensation Committee is available on our website at www.clearsign.com (under “Investors”).

The Compensation Committee may form and delegate a subcommittee consisting of one or more members to perform the functions of the Compensation Committee. The Compensation Committee may engage outside advisers, including outside auditors, attorneys and consultants, as it deems necessary to discharge its responsibilities. The Compensation Committee has sole authority to retain and terminate any compensation expert or consultant to be used to provide advice on compensation levels or assist in the evaluation of director, President/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.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee, or the “Governance Committee”, consists of three independent directors, as that term is defined in section 5605(a)(2) of the NASDAQ Listing Rules. The Governance Committee met two times during 2012 with all members in attendance at each meeting. The role of the Governance Committee is to:

evaluate from time to time the appropriate size (number of members) of the Board and recommend any increase or decrease;
determine the desired skills and attributes of members of the Board, taking into account the needs of the business and listing standards;
establish criteria for prospective members, conduct candidate searches, interview prospective candidates, and oversee programs to introduce the candidate to us, our management, and operations;

TABLE OF CONTENTS

review planning for succession to the position of Chairman of the Board and Chief Executive Officer and other senior management positions;
annually recommend to the Board persons to be nominated for election as directors;
recommend to the Board the members of all standing Committees;
adopt or develop for Board consideration corporate governance principles and policies; and
periodically review and report to the Board on the effectiveness of corporate governance procedures and the Board as a governing body, including conducting an annual self-assessment of the Board and its standing committees.

A copy of the charter of the Governance Committee is available on our website at www.clearsign.com (under “Investors”).

Policy with Regard to Security Holder Recommendations

The Governance Committee does not presently have a policy with regard to consideration of any director candidates recommended by security holders. No security holder (other than members of the Governance Committee) has recommended a candidate to date. The Governance Committee plans to adopt a policy prior to the next annual meeting of our security holders.

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 have substantial experience with one or more publicly traded 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 of Directors, 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 the three non-management directors.

Compensation Committee Interlocks and Insider Participation

During 2012, Lon E. Bell (Chair), Steven E. Pirnat, and Scott P. Isaacson served on the Compensation Committee. None of these individuals has ever been an officer or employee of ours. In addition, none of our 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 Conduct

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 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”).

TABLE OF CONTENTS

Risk Oversight

Enterprise risks are identified and prioritized by management and each prioritized risk is assigned to a Board committee or the full Board for oversight as follows:

Full Board — Risks and exposures associated with strategic, financial and execution risks and other current matters that may present material risk to our operations, plans, prospects or reputation.

Audit Committee — Risks and exposures associated with financial matters, particularly financial reporting, tax, accounting, disclosure, internal control over financial reporting, financial policies, investment guidelines and credit and liquidity matters.

Governance Committee — Risks and exposures relating to corporate governance and management and director succession planning.

Compensation Committee — Risks and exposures associated with leadership assessment, and compensation programs and arrangements, including incentive plans.

Board Leadership Structure

The Chairman of the Board presides at all meetings of the Board. The Chairman is appointed on an annual basis by at least a majority vote of the remaining directors.

Review, Approval or Ratification of Transactions with Related Persons

The Board of Directors reviews issues involving potential conflicts of interest, and reviews and approves all related party transactions, including those required to be disclosed as a “related party” transaction under applicable federal securities laws. The Board has not adopted any specific procedures for conducting reviews of potential conflicts of interest and considers each transaction in light of the specific facts and circumstances presented. However, to the extent a potential related party transaction is presented to the Board, the Company expects that the Board would become fully informed regarding the potential transaction and the interests of the related party, and would have the opportunity to deliberate outside of the presence of the related party. The Company expects that the Board would only approve a related party transaction that was in the best interests of, and fair to, the Company, and further would seek to ensure that any completed related party transaction was on terms no less favorable to the Company than could be obtained in a transaction with an unaffiliated third party.

Compliance with Section 16 of the Exchange Act

Based solely upon a review of Forms 3, 4 and 5 furnished to the Company, the Company believes that all of its directors, officers and applicable stockholders timely filed these reports, with the exception of James N. Harmon who failed to timely file one Form 4. The report was filed 18 days after the due date. The transactions related to the cancellation of a stock award previously granted to Mr. Harmon and the grant of a new award. Both awards were made from the Company's 2011 Equity Incentive Plan. The cancellation of the original award and the grant of the new award did not result in a change to the number of shares of common stock Mr. Harmon owned on the date the transactions occurred.

PROPOSAL 1 — ELECTION OF DIRECTORS

Nominees for Election

The Board currently has five members. Our Board, upon the recommendation of the Governance Committee, has nominated each of our incumbent directors for re-election at the Annual Meeting. Each nominee has agreed, if elected, to serve a one-year term or until the election and qualification of his 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.

PROPOSAL 2 — RATIFICATION OF 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 financial statements for the fiscal year ending December 31, 2013. Gumbiner Savett Inc. has served as our independent registered public accounting firm since 2011.

Stockholder ratification of the selection of Gumbiner Savett Inc. as our independent registered public accounting firm is not required by our Bylaws or the Washington Business Corporation Act. The Board seeks such ratification as a matter of good corporate practice. Should the stockholders fail to ratify the selection of Gumbiner Savett Inc. as our independent registered public accounting firm, the Board will reconsider whether to retain that firm for fiscal year 2013. In making its recommendation to the Board that stockholders ratify the appointment of Gumbiner Savett Inc. as our independent registered public accounting firm for the fiscal year ending December 31, 2013, the Audit Committee considered whether Gumbiner Savett Inc.’s provision of non-audit services is compatible with maintaining the independence of our independent registered public accounting firm. 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.

   
  2012   2011
Audit Fees   $ 40,355     $ 36,726  
Audit Related Fees     4,900       10,807  
Tax Fees     2,149       6,000  
All Other Fees     13,344        

Audit Fees.  The “Audit Fees” are the aggregate fees of Gumbiner Savett Inc. attributable to professional services rendered in 2012 and 2011 for the audit of our annual financial statements and for review of financial statements included in our quarterly reports on Form 10-Q or for services that are normally provided by Gumbiner Savett Inc.in connection with statutory and regulatory filings or engagements for those fiscal years. These fees include fees billed for professional services rendered by Gumbiner Savett Inc. for the review of registration statements or services that are normally provided in connection with statutory and regulatory filings or engagements for those fiscal years.

Audit-Related Fees.  Gumbiner Savett Inc. performed professional services in association with the initial public offering filed in November 2011 including amendments filed through the effective date of April 25, 2012 that were reasonably related to the performance of the audit or review of financial statements that are not included under Audit Fees above.

Tax Fees.  Gumbiner Savett Inc. billed for professional services rendered for tax compliance, tax advice, and tax planning.

All Other Fees.  Gumbiner Savett Inc. performed customary agreed upon professional services in connection with our initial public offering.

Pre-approval Policies and Procedures

The Audit Committee is required to review and approve in advance the retention of the independent auditors for the performance of all audit and lawfully permitted non-audit services and the fees for such services. The Audit Committee may delegate to one or more of its members the authority to grant pre-approvals for the performance of non-audit services, and any such Audit Committee member who pre-approves a non-audit service must report the pre-approval to the full Audit Committee at its next scheduled meeting. The required pre-approval policies and procedures were complied with during 2012 and 2011.

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

The affirmative vote of the holders of shares of common stock entitled to vote must exceed the votes cast against this proposal for the proposal to be approved.

The Board recommends that stockholders vote “FOR” ratification of the appointment of Gumbiner Savett Inc. as our independent registered public accounting firm for the fiscal year ending December 31, 2013 as described in this Proposal 2.

PROPOSAL 3 — APPROVAL OF THE CLEARSIGN COMBUSTION CORPORATION 2013 CONSULTANT STOCK PLAN

We are asking our stockholders to approve the ClearSign Combustion Corporation 2013 Consultant Stock Plan (the “Plan”), pursuant to which 75,000 shares of the Company's common stock will be reserved for issuance as stock grants (“Awards”). On March 18, 2013, our Board adopted the Plan to allow the Company to issue unregistered shares of our common stock to compensate individuals who provide us with capital raising and investor relations services and services related to making a market in or promoting the Company's securities, subject to and in compliance with applicable federal and state securities laws. A copy of the full text of the Plan is available for review at our principal offices and we will furnish a copy to our stockholders without charge upon written request directed to ClearSign Combustion Corporation, 12870 Interurban Avenue South, Seattle, WA 98168, Attention: Corporate Secretary.

The following summary describes the material features of the Plan. The summary, however, does not purport to be a complete description of all the provisions of the Plan.

Description of the Plan

The Plan provides for the granting of shares of common stock to consultants who provide us with capital raising and investor relations services and services related to making a market in or promoting the Company's securities (the “Recipients”). None of our officers, directors or employees will be entitled to receive awards from the Plan. The Company reserved 75,000 shares of common stock for issuance under the Plan (the “Plan Shares”). The Plan provides for periodic increases in the number of authorized shares available for issuance under the Plan on the first day of each of the Company’s fiscal quarters beginning April 1, 2013. The quarterly increases are equal to 1% of any new shares subsequently issued by the Company or such lesser amount as the Board of Directors shall determine. If Plan Shares are forfeited, repurchased, or otherwise reacquired by the Company, such Plan Shares will again become available for sale or award under the Plan. The Compensation Committee of the Board of Directors is authorized to administer the Plan and establish the grant terms, including the grant price, vesting period and exercise date.

Each sale or award of Plan Shares under the Plan is made pursuant to the terms and conditions provided for in an award agreement (an “Award Agreement”) entered into by the Company and the individual Recipient. There have been no awards made from the Plan.

The number of Plan Shares covered by each outstanding Award Agreement shall be proportionately adjusted for (a) 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 similar transaction affecting the common stock or (b) any other increase or decrease in the number of issued shares of common stock effected without receipt of consideration by the Company.

The Plan may be amended, suspended or terminated by the Board at any time and for any reason.

Vote Required and Recommendation

The affirmative vote of the holders of shares of stock entitled to vote must exceed the votes cast against the proposal for the proposal to be approved.

The Board recommends that stockholders vote “FOR” the approval of the ClearSign Combustion Corporation 2013 Consultant Stock Plan as described in this Proposal 3.

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

On December 27, 2011 we entered into an Employment Agreement with Richard Rutkowski, our Chief Executive Officer. The agreement was effective on January 1, 2012 and, unless earlier terminated, will continue for a term of 3 years and for successive 2 year periods as agreed to by Mr. Rutkowski and the Company. Mr. Rutkowski's annual salary will be $350,000 during the term of the agreement. A cost-of-living adjustment will be made to the annual salary each year of the term. The Compensation Committee may grant an annual bonus to Mr. Rutkowski based on performance standards and goals achieved by him. During the term of the agreement, we have agreed to provide, at our sole expense, (i) medical and dental benefits for Mr. Rutkowski, his spouse and children, (ii) disability insurance which, in the event of a disability, will replace 60% of the annual salary paid to Mr. Rutkowski at the time the disability occurred, and (iii) term life insurance in the amount of $1,750,000. No later than 30 days after each annual anniversary of the effective date of the agreement, we will grant to Mr. Rutkowski an option to purchase shares of our common stock in an amount to be recommended by the Compensation Committee. The agreement may be terminated for cause, or without cause due to Mr. Rutkowski's death or disability, at his election, at our election, or as a result of a change of control. If the agreement is terminated as a result of Mr. Rutkowski's death, disability or by his election, Mr. Rutkowski will receive accrued but unpaid annual salary and the value of accrued but unused vacation pay through the effective date of the termination, accrued but unpaid annual bonus, if any and business expenses incurred prior to the effective date of termination. If we terminate the agreement without cause, Mr. Rutkowski will receive accrued but unpaid annual salary and the value of accrued but unused vacation pay through the effective date of the termination, accrued but unpaid annual bonus, if any, business expenses incurred prior to the effective date of termination and the greater of the salary that would be due to him if his employment had not been terminated or 12 months of annual salary, less legal deductions. Mr. Rutkowski would also be entitled to continue to participate in employee benefit plans for a period of 12 months following termination of his employment. If his employment is terminated as a result of a change of control, Mr. Rutkowski will receive accrued but unpaid annual salary and the value of accrued but unused vacation pay through the effective date of the termination, accrued but unpaid annual bonus, if any, business expenses incurred prior to the effective date of termination and an amount equal to his annual salary for the balance of the term, in a lump sum and without discount to present value, but in no event shall such payment total less than the annual salary.

All of the Company’s Option Awards and Stock Awards for its executives include change-in-control arrangements whereby any unvested stock options would vest or any bargain repurchase options for stock grants would terminate as a result of a change in control.

Compensation Discussion

Overview

The Compensation Committee of the Board of Directors 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. Our Chief Executive Officer assists the Compensation Committee in its deliberations with respect to the compensation payable to our other executive officers, and typically recommends specific compensation packages for our executive officers based upon his assessment and evaluation of their performance.

TABLE OF CONTENTS

Following the end of each fiscal year, our Chief Executive Officer evaluates executive officer performance for the prior fiscal 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 for the prior fiscal 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 packages 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 2012, the Compensation Committee engaged Buck Consultants to evaluate our executive compensation program. The objective was to determine the equity 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 study into its evaluation of executive compensation in 2012 and expects to reference it in the future as a framework for executive compensation.

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 of our current NEOs as well as any additional individuals identified as NEOs 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 beneficial ownership of within 60 days of March 6, 2013 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 within 60 days of March 6, 2013 are considered to be outstanding. These shares, however, are not considered outstanding as of March 6, 2013 when computing the percentage ownership of each other person.
