<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">ClearSign Technologies Corporation
(the &ldquo;Company&rdquo;) is filing this Amendment No. 1 on Form 10-K/A (this &ldquo;Amendment&rdquo;) to amend the Company&rsquo;s
Annual Report on <A HREF="https://www.sec.gov/Archives/edgar/data/1434524/000110465921044241/tm211074d1_10k.htm" STYLE="-sec-extract: exhibit">Form 10-K</A> for the year ended December 31, 2020 (&ldquo;Form 10-K&rdquo;), originally filed with the Securities and Exchange
Commission (the &ldquo;SEC&rdquo;) on March 31, 2021. The sole purpose of this Amendment is to include the information required by Items
10 through 14 of Part III of Form 10-K, which was previously omitted from the Form 10-K in reliance on General Instruction G(3) to Form
10-K, which permits the information in the above-referenced items to be incorporated in the Form 10-K by reference from the Company&rsquo;s
definitive proxy statement if such statement is filed no later than 120 days after the Company&rsquo;s fiscal year-end. The Company is
filing this Amendment to include Part III information in the Form 10-K because a definitive proxy statement containing such information
will not be filed by April 30, 2021. Further, because the Company is a &ldquo;smaller reporting company,&rdquo; as defined in Item 10
of Regulation S-K promulgated under the Securities Exchange Act of 1934 (the &ldquo;Exchange Act&rdquo;), the Company has elected to provide
in this Amendment certain scaled disclosures permitted under the Exchange Act for smaller reporting companies. Except as set forth in this
Amendment, no other changes are made to the Form 10-K. Unless expressly stated, this Amendment does not reflect events occurring after
the filing of the Form 10-K, nor does it modify or otherwise update in any way the disclosures contained in the Form 10-K. Accordingly,
this Amendment should be read in conjunction with the Form 10-K and with the Company&rsquo;s filings with the SEC subsequent to the filing
of the Form 10-K.</P>

the Securities Exchange Act of 1934, as amended, this Amendment also contains certifications pursuant to Section 302 of the Sarbanes-Oxley
Act of 2002, which are attached hereto. Because no financial statements have been included in this Amendment and this Amendment does not
contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have
been omitted.</P>

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&rsquo;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.</P>

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 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&rsquo;s performance during the
year based upon subjective factors concerning such officer&rsquo;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

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, 2019, and 2020. Willis Towers Watson provided
no other services to us following the evaluation. The Compensation Committee is currently reviewing compensation trends, especially at

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On January 28, 2019 (the &ldquo;Effective
Date&rdquo;), 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&rsquo;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&rsquo;s common stock at an exercise price of $1.16 per share and an option
to purchase 200,000 shares of the Company&rsquo;s 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; the right to purchase one-third of the shares will vest on the first anniversary of the grant date; and the right to purchase one-third
of the shares will vest on the second anniversary of the grant date. The Company has agreed to pay certain expenses, not to exceed the
sum of $100,000, related to Dr. Deller&rsquo;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 &ldquo;Relocation
Adjustment&rdquo;), for a period of four years (the &ldquo;Payment Period&rdquo;) 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&rsquo;s death or disability, upon 30 days&rsquo;
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&rsquo;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.</P>

placement of the Company&rsquo;s common stock pursuant to a Stock Purchase Agreement dated July 12, 2018, the Company granted to clirSPV
LLC a right to purchase certain new equity securities that the Company sells for the purpose of raising capital on terms and conditions
no different from those offered to other purchasers (the &ldquo;Participation Right&rdquo;) so that it could maintain a 19.99% percentage
ownership (the Percentage Ownership&ldquo;) of the Company&rsquo;s outstanding common stock. The Participation Right will expire on December
31, 2023. Further, in conjunction with this investment made by clirSPV LLC, we entered into a Voting Agreement with clirSPV LLC pursuant
to which Mr. Hoffman was named as a director.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Because certain elements of
the Participation Right, such as the notice provisions, were not compatible with the Offering<FONT STYLE="background-color: white">, in
a written waiver dated August 18, 2020, and fully executed on August 19, 2020, </FONT>clirSPV LLC <FONT STYLE="background-color: white">waived
its right to exercise the Participation Right in connection with the Offering. In lieu of participating in the Offering, the Company and
</FONT>clirSPV LLC <FONT STYLE="background-color: white">agreed that, following the initial closing of the Offering, </FONT>clirSPV LLC
<FONT STYLE="background-color: white">may purchase from the Company, at the price sold to investors in the Offering, unregistered shares
of its common stock in a number that will allow it to maintain its Percentage Ownership. </FONT>In September 2020, clirSPV LLC exercised
this right and purchased 654,425 shares of our common stock at a price of $2.00 per share.</P>
