On February 18, 2023, Susanne Meline notified the Board of Directors (the "Board") of ClearSign Technologies Corporation (the "Company") that she will resign from the Board, effective immediately prior to the appointment of Catharine de Lacy as a member of the Board, which occurred on February 21, 2023 (the "Effective Date"), as more fully described below. At the time of her resignation, Ms. Meline was the chairperson of the Board's Nominating and Corporate Governance Committee (the "Nominating Committee"), a member of the Board's Audit Committee (the "Audit Committee") and Compensation Committee and the Board's Lead Independent Director. On February 18, 2023, the Board, upon Ms. Meline's resignation, appointed Judith Schrecker to be the Board's new Lead Independent Director. Ms. Meline's decision to resign was not as a result of a disagreement with the Company, known to an executive officer of the Company, on any matter relating to the Company's operations, policies or practices.

As an independent director, Ms. de Lacy has also been appointed to serve as chairperson of the Nominating Committee and as a member of the Audit Committee.

Ms. de Lacy, age 64, has extensive experience in environmental, social and corporate governance ("ESG"), public affairs and risk management in a wide range of industries, including oil and gas, energy markets, manufacturing and others. Since 2007, Ms. de Lacy has served as the co-founder and managing director of Riar Associates, LLC, where she advises clients on a variety of topics, including ESG. From 2015 to 2020, Ms. de Lacy held management positions at Albemarle Corp., focusing on public and regulatory affairs, and sustainability. Before that, Ms. de Lacy was the Vice President of Global Stewardship at Clorox Corp. from 2011 to 2015. Ms. de Lacy also has board of directors experience, having served as a director, chairperson of the environmental health and safety committee and member of the audit committee of TORC Oil & Gas, Ltd., a company that was previously listed on the Toronto Stock Exchange from 2019 to 2021, and NTES LLC, a private company. Ms. de Lacy has a Bachelor of Science (B.S.) in Chemistry from Merrimack College, a Master of Science (M.S.) in Environmental Engineering and Public Health and multiple certifications, including a "Corporate Director Certificate" from Harvard Business School, a "Certificate of Risk Governance, and as a Qualified Risk Director" certificate from the DCRO Institute and an ESG Board Certification from UC Berkeley Law School.

In connection with her appointment, Ms. de Lacy received an offer letter from the Company, dated as of February 20, 2023 and effective as of the Effective Date (the "Offer Letter"), setting forth the terms of Ms. de Lacy's services as a director and her compensation arrangement, which she accepted. Pursuant to the Offer Letter and in accordance with the Company's director compensation policies, Ms. de Lacy will be granted restricted stock units ("RSUs") under the Company's 2021 Equity Incentive Plan valued on the grant date, which is the first day of every quarter that Ms. de Lacy serves on the Board (the "Grant Date"), at $15,000 for serving as a member of the Board, $1,625 for serving as chairperson of the Nominating Committee and $1,875 for serving as a member of the Audit Committee (such initial grant being the pro-rated portion of RSUs for the quarter ending March 31, 2023), and which amounts will then be payable quarterly on every Grant Date.

The foregoing description of the Offer Letter does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to the Offer Letter, which is included as Exhibit 10.1 to this Current Report on Form 8-K.

In connection with her appointment, Ms. de Lacy has also entered into the Company's standard form of indemnification agreement, the form of which is filed as Exhibit 10.18 to the Company's Registration Statement on Form S-1 filed with the SEC on November 14, 2011.

There are no arrangements or understandings between Ms. de Lacy and any other person pursuant to which he was selected as a director. There are no family relationships between Ms. de Lacy and any of our officers and directors and there is no transaction between the Company and Ms. de Lacy that is required to be disclosed pursuant to Item 404(a) of Regulation S-K.

Catharine de Lacy

Re: <u>Board of Directors of ClearSign Technologies Corporation - Offer Letter</u>

Dear Catharine de Lacy:

On behalf of ClearSign Technologies Corporation (the "<u>Company</u>," "<u>ClearSign</u>," "<u>we</u>," "<u>our</u>" or "<u>us</u>") and our Board of Directors ("<u>Board</u>"), I am pleased to offer you a position as a member of our Board. We look forward to working with you on the Board. Should you choose to accept this position as a member of the Board, including potential service on committees of the Board, this letter shall constitute an agreement (the "<u>Agreement</u>") between you and the Company and contains all the terms and conditions relating to the services to be provided.

1. <u>Term</u>. This Agreement shall be through the date of the
next annual shareholders' meeting expected in early June 2023 and commencing on February 21, 2023. Your term as director shall
continue until your successor is duly elected and qualified. The position shall be up for re-election each year at the annual shareholders'
meeting and upon re-election, the terms and provisions of this Agreement shall remain in full force and effect. You also agree to resign
from the Board of Directors if requested by a majority of the then-sitting members of the Board. This Agreement shall be in effect as
long as you are a director on the Board.

2. <u>Services</u>. You shall render services in the area of managing
or directing the Company's property, affairs and business (hereinafter, your " <u>Duties</u> "). You shall consult with other
members of the Board at meetings held quarterly, or more regularly if required, in locations determined by the Chairman of the Board
of the Company. You agree that your relationship with the Company will be that of a director and not that of an employee. Nothing in
this Agreement is intended to replace, supersede or diminish any of your duties to the Company as a director under state law. You also
agree to comply with all federal and state securities laws as well as Company policies, as applicable.

3. <u>Services for Others</u>. You are free to represent or perform
services for other persons during the term of this Agreement. However, you agree that you do not presently perform and do not intend
to perform, during the term of this Agreement, similar Duties, consulting or other services for companies whose businesses are or would
be, in any way, in conflict or competitive with the Company (except for companies previously disclosed by you to the Company in writing).
Should you propose to perform similar Duties, consulting or other services for any such company, you agree to notify the Company in writing
in advance (specifying the name of the organization for whom you propose to perform such services) and to provide sufficient information
to the Company to allow it to determine if the performance of such services would conflict with areas of interest to the Company.

4. <u>Compensation to Independent Directors</u>. In consideration
for your service as a member of the Board of Directors of the Company, you will receive an award of restricted
stock units valued at $15,000 on the grant date, which will be the first day of every quarter that you serve on the Board. The Company
may also award additional restricted stock units to you on the first day of each quarter, with values ranging from $750 to $1,875 per
quarter, should you join any board committees. These restricted stock units will vest upon death, departure from the board or a "change
of control," as such term is defined in the applicable Agreement as determined by the Compensation Committee and in accordance
with the terms and conditions of the Company's 2021 Equity Incentive Plan. The Company will also reimburse you for reasonable expenses
incurred in connection with the performance of your Duties as a director in accordance with the Company's expense policy then in
effect. Should you join the Board or any committee of the Board after the first day of any quarter, you will receive an award of restricted
stock units that is pro-rated for the number of days remaining in such quarter.

5. <u>D&O Insurance Policy</u>. You will be entitled to coverage
under our Directors and Officers liability insurance as then in effect.

6. <u>Assignment</u>. Because of the personal nature of the services
to be rendered by you, this Agreement may not be assigned by you. The Company shall be free to transfer any of its rights under this
Agreement to any affiliate or third party.

7. <u>Confidential Information; Non-Disclosure</u>. In consideration

**Exhibit 99.1**

![](tm237744d1_ex99-1img001.jpg)

**ClearSign Technologies Corporation Announces Board Transitions**

Tulsa, OK, February 23, 2023 -- ClearSign Technologies Corporation (Nasdaq: CLIR) ("ClearSign" or the "Company"), an emerging leader in industrial combustion and sensing technologies that improve energy and operational efficiency, and safety while dramatically reducing emissions, today announces that Susanne Meline is stepping down from the ClearSign Board of Directors. Concurrently, the Company announces the appointment of industry veteran Catharine de Lacy to the open board position.

Catharine de Lacy is a widely recognized expert in ESG/Sustainability initiatives, public affairs, corporate governance, and risk management. She is known for her track record working with companies to enhance relationships with regulatory authorities, investors, suppliers and customers and reduce cycle time to market for new products. Ms. de Lacy is well versed across diverse industries having worked for both public and privately held companies including Albemarle Corporation, the Clorox Corp., Sun Products, Cabot Corp, AlliedSignal, and Occidental Petroleum Corp. in her capacities of a Corporate Officer and Global VP.<br>Catharine is the co-founder and Managing Director of Riar Associates, LLC, a management consultancy where she continues to work as a business advisor and subject matter expert on ESG, sustainability, business strategy, public policy and advocacy, communications, and risk management matters for public and private companies, banking and investment firms, professional services firms, and nonprofit organizations. She is a former board member of TORC Oil & Gas, Ltd. (TSX:TOG), and is currently serving as a board member of privately-held NTES LLC, which provides strategic, financial, and operations management expertise in evolving energy markets and real estate investment; a member of the Environmental Law Institute's Leadership Council; and in the Executive Advisory Council of the Responsible Battery Coalition. Ms. de Lacy also regularly contributes to ESG educational programs as a board member of the National Association of Corporate Directors' Carolinas Chapter and leads its Member Engagement Committee. She holds a Board Certificate in ESG from UC Berkeley's Law School, is a Certified Director through the Harvard Business School, holds a certificate in Risk Governance from the DCRO, and is also a Qualified Risk Director®. Ms. de Lacy received a B.A. from Merrimack College, and an M.S. from Tufts University.

"I want to thank Susanne for her five years of service and support of ClearSign," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "Over her tenure, Susanne has led every board committee at ClearSign, including serving as our Lead Independent Director, and has been integral to achieving the best possible results in all of our capital raises. I have appreciated her voice and counsel over the years and believe she has left the company in a good position to further our commercial growth," continued Dr. Deller.

"I am very pleased to welcome Catharine de Lacy to the ClearSign board. I look forward to working with her and the benefits of adding her industry experience and ESG-related capabilities to our collective board expertise," said Jim Deller, Ph.D.

"I am proud of the advancements that ClearSign has made over my time serving on Board," said Susanne Meline. "I am excited about the addition of Catharine to the Board, and her potential to assist the Company's future commercial growth including connecting with customers, resources, investors and other constituents who seek out the Company, its securities and its products not only for their own merit but also due to their ability to reduce the emission of toxic airborne pollutants. The recent sales of boiler burners show that business segment is starting to gain traction while the continued execution of commercial orders in process burners will help the proliferation of the Company's technology. I have full confidence in Jim Deller's leadership and look forward to the contributions that Catharine de Lacy can bring to the Board and Company."
