11, 2012 - ClearSign Combustion Corporation (Nasdaq: CLIR), </FONT>an emerging leader in combustion and emissions control technology
for industrial, commercial and utility markets<FONT STYLE="color: black">, today announced its results for the first quarter ended
March 31, 2012. The Company incurred a loss of $865,000 as compared to a loss of $892,000 in the first quarter of 2011. Research
and development costs incurred in the first quarter totaled $264,000 as compared to $23,000 in the first quarter of 2011, reflecting
increased personnel levels and research activities. General and administrative costs decreased to $600,000 in the first quarter
as compared to $869,000 in the first quarter of 2011. The first quarter of 2011 included a non-recurring consulting expense of
$675,000, which was partially offset by increased personnel levels in the first quarter of 2012. As a development stage company,
ClearSign has recorded no revenue to date.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;We are pleased to report that we have made
significant progress against both our technical and business development goals during the first quarter,&rdquo; said ClearSign
CEO, Rick Rutkowski &ldquo;This trend has continued in the current quarter.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;We recently completed our initial public offering,
raising gross proceeds of $13.8 million and strengthening both our balance sheet and our shareholder base.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;During the first quarter we completed the construction
of our primary research furnace that will accommodate burners with thermal output up to one million Btu/hr.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;Over the last two quarters we have demonstrated
multiple significant effects with our technology using diverse fuels in the range of 100,000 to 150,000 Btu/hr. We have demonstrated
effects that relate to improvements in the control of flame shape, flame stability (and flame speed), flame chemistry and flame
radiance or luminosity as compared to conventional techniques for combustion systems design. During this period, we have also developed
substantial new intellectual property. Our experiments suggest that our technology can be used to reduce or eliminate multiple
criteria pollutants at the flame source while simultaneously increasing heat transfer efficiency and improving heat distribution.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;In the course of our work since that time, we
have developed a series of enhancements to techniques for stabilizing flames and simplifying burner design for low NOx and Ultra-Low
NOx burners which we believe are both unique and highly innovative. We believe that our technology may enable performance improvements
that can result in substantial savings for customers. We are pursuing multiple new patent applications and continue to invent aggressively.</P>

our technology at a scale of 250,000 Btu/hr. and to reach a commercially relevant scale of 1,000,000 Btu/hr by the end of the current
year. During the first quarter we put in place additional resources in support of this goal, and we believe that we will be able
to report on the results of our earliest experiments at this scale in the days ahead, prior to the end of the current quarter.</P>

on identifying and selectively engaging with prospective OEM partners, channel partners and launch customers in multiple segments
of the combustion market. Our goal is to 1) inform product definition from the perspective of both customers and the distribution
channel (refine pricing models, product roadmap and launch strategy), 2) secure agreements with high visibility launch customers
for early commercialization of our systems, and 3) engage with subject matter experts and thought leaders in the combustion field.</P>
