<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">SEATTLE, November
12, 2018 &ndash; ClearSign Combustion Corporation (Nasdaq: CLIR) (&quot;ClearSign&quot; or the &quot;Company&quot;), an emerging
leader in industrial combustion technologies that improve energy and operational efficiencies while dramatically reducing emissions,
commented today on the filing made by Anthony DiGiandomenico with the Securities and Exchange Commission of a preliminary solicitation
statement seeking the support of the Company&rsquo;s shareholders in making a demand that the Company call a special meeting of
shareholders to vote for a the removal of the existing entire board of directors and to elect a new slate of directors, among other
matters.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&ldquo;Mr. DiGiandomenico&rsquo;s
request is an attempt to bypass our previously announced succession plans and place unvetted candidates on the board and in the
CEO position. We urge you to reject his request for support to call a special meeting,&rdquo; said Rob Hoffman, ClearSign Chairman
of the Board. &ldquo;The Company has maintained an active dialogue with him, as we will detail in our upcoming filing with the
SEC, as well as with other shareholders in an effort not only to understand their concerns, but to resolve shareholder concerns
while simultaneously following best corporate governance practices. Despite these good faith efforts, however, he wishes to replace
directors without the benefit of a process that ensures that the Company can consider a broad variety of potential candidates and
take into consideration the skills and experience of the new CEO.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&ldquo;On October
1<SUP>st</SUP>, we announced the Company&rsquo;s leadership succession plans which included my intention to retire from ClearSign,
the engagement of a nationally recognized search firm to assist with the Board&rsquo;s CEO recruitment efforts and my commitment
to ensuring a smooth transition&rdquo; said Steve Pirnat, ClearSign CEO. &ldquo;Additionally, at that time, director&nbsp;Jeffrey
Ott stepped down from the board to focus on his other responsibilities and commitments. Rather than rush to find a replacement,
we stated our intention to consider new board members, with an emphasis on diversity of talents and backgrounds. In addition, on
November 6<SUP>th</SUP> the board voted, in line with best corporate governance practices, to separate the roles of CEO and Chairman
and appointed Rob Hoffman to serve as Chairman, effective immediately.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&ldquo;As I mentioned
on our quarterly call, the Board has actively been vetting and meeting with CEO candidates,&rdquo; said Rob Hoffman. &ldquo;Additionally,
the Board recognizes the value of refreshing its membership and we are casting a wide net in searching for new members, including
working with the National Association of Corporate Directors to find director candidates. Importantly, at a meeting held on October
30th, the Board considered the annual compensation paid to non-executive directors and intends to not only reduce total compensation
paid to Board members, but also change from a cash-based to an all-equity based compensation structure, so that the interests of
the non-executive directors are more fully aligned with our shareholders. The members of the Board have also decided to accelerate
the scheduling of the Company&rsquo;s annual meeting to the earliest practical date in order to introduce the Company&rsquo;s shareholders
to the new Board members,&rdquo; said Mr. Hoffman.</P>

a proxy contest to replace our board members will not yield a slate of directors materially earlier than the Company&rsquo;s own
process, which is currently well underway. But acting in undo haste may yield a result contrary to the best interests of all Clearsign
shareholders by seating a board that may not be optimal to lead the Company in the exciting times ahead. Further, a wholesale turnover
in leadership at the Board and senior management level at this critical commercial juncture for the Company may create costly,
if not fatal setbacks to the progress made thus far. It should be noted that the Company has already added two new board members
(of five) during the year &ldquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; background-color: white">&ldquo;We remain
committed to a prudent, disciplined, thoughtful, step-by-step evaluation of new candidates, which takes into consideration the
current transition in corporate leadership as well as future board leadership needs while maintaining the strong and very promising
internal focus on the Company&rsquo;s pipeline of commercial opportunities that we seek to convert into revenue for the Company
and the creation of shareholder value for all CLIR investors. It is this focus, we believe, that will enable us to deliver significant
shareholder value in the future rather than a costly and disruptive proxy contest which, at most, may slightly accelerate the board
nomination process,&quot; concluded Pirnat.</P>
