<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt"><FONT STYLE="color: black">SEATTLE, WA &ndash; JUNE
19, 2012 - ClearSign Combustion Corporation (Nasdaq: CLIR),</FONT> an emerging leader in combustion and emissions control technology
for industrial, commercial and utility markets, reported today that it has successfully demonstrated its proprietary Electrodynamic
Combustion Control&trade; (ECC&trade;) technology operating in a system with a thermal output of more than 400,000 Btus per hour.</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">According to Joe Colannino, the company&rsquo;s Chief
Technology Officer, the demonstration represents a key milestone in the path to commercializing the company&rsquo;s technology.</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">&ldquo;We have exceeded our goal of 250,000 Btu/hr
for the current quarter and moved closer to our key commercialization milestone of one million Btu/hour which continues to be our
target for the end of this year.</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">&ldquo;The purpose of this demonstration was to show
that a flame can be stabilized and anchored at a selected location by using ClearSign&rsquo;s ECC technology to dramatically accelerate
the rate of combustion,&rdquo; said Colannino. &ldquo;We believe that this technique will allow us to reduce emissions of Nitrogen
Oxides (NOx) to very low levels while at the same time radically simplifying burner design. Improved flame stability is also commercially
very significant because it can translate directly to significant savings in fuel consumption for many industrial scale systems.&rdquo;</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">The company says that its technology can be used to
anchor a flame to virtually any designated location above the gas nozzle, even with the fuel moving at a very high velocity. This
is significant because normally a flame (even under turbulent conditions) cannot burn fast enough to counter the force of the gas
jet.</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">ClearSign CEO, Rick Rutkowski, says this effect is
unique and unprecedented. &ldquo;The only way to burn back against this high velocity gas jet is to actually increase the reaction
rates. The flame is able to stabilize because it is now burning at a speed that more closely matches that of the gas jet.</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">&ldquo;Our commercial goal is to enable a whole range
of proprietary combustion solutions based on this technique. We believe that there are numerous &ldquo;high value&rdquo; commercial
and industrial applications where the ability to accelerate and control the rate of combustion can be translated to significant
design improvements and substantial savings in both capital and operating costs for users&rdquo;.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;News of this development should be very well
received by prospective customers and partners,&rdquo; added Rutkowski. &ldquo;We have generated substantial interest among prospective
launch customers, as well as with several leading combustion system OEMs and engineering and construction firms.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;We believe that our technology is a powerful
tool that our customers will be able to use to reverse the trend of rapidly escalating costs in complying with air quality regulations,&rdquo;

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;We believe that ECC offers the potential to
dramatically reduce the high recurring cost associated with control of NOx emissions and will feature a much lower total cost of
ownership than current generation technology. These are well known problems and costs that have defied a solution for a long time.
I think the market is going to welcome this development.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">According to the company, improved flame stability
is just one of several powerful combustion control effects enabled by ECC technology. The technology can also be used to improve
control of flame shape, to reduce or eliminate emissions of multiple pollutants including particulate, NOx and CO (Carbon Monoxide)
and to improve both heat transfer efficiency and heat distribution. Each of these effects has significant commercial implications
independently and can be combined in many cases to yield even more powerful advantages. The company will be conducting and reporting
on additional experiments on each of these effects at the newly increased scale.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;Our goal is to turn the economics of emissions
control on its head.&quot; said Rutkowski. &ldquo;We believe our technology will enable our customers to reduce multiple types
of emissions by suppressing them at the source and at the same time, will increase system efficiency, throughput and overall productivity.
The ability to combine increased efficiency with emissions control is unprecedented and, potentially, a sea change. We&rsquo;re
talking about a world where environmental compliance is no longer a cost but instead a source of additional profit and return on
invested capital. That&rsquo;s great news for both industry and the environment.&rdquo;</P>

sales of air pollution control equipment in 2011 were $42 billion. There are approximately 163,000 boilers operating at the commercial
and industrial scale in the US.</P>
