"Just a few days ago, we reported what we believe may be a significant technological breakthrough, resulting from an effort that began during the 4th quarter of this year. We were asked by a key prospective customer in the oil refinery market to reduce flame length by 30% without increasing NOx emissions. This is an important goal that, if achieved, would resolve costly compromises between effective emissions control and process throughput and energy efficiency in refinery heaters.

"To do this, we developed a highly innovative two-tiered 'duplex' burner architecture that has allowed us to significantly exceed this requirement and reduce flame length by as much as 80%. In accordance with the customer's requirement, we did not increase NOx, and in fact, were able to reduce it. We plan to publish more data on this in the coming weeks. We believe that this novel approach may be broadly applicable to burner design for a wide range of potential applications. The improved flame shape may have significant implications for increasing refinery process throughput and production yields.

"Our business development activities have also been successful and we have identified significant launch opportunities in several large market segments including:

•Refinery heaters,

•Ultra Low NOx burners for a broad range of commercial and industrial applications including package boiler and process heaters,

•Commercial and industrial solid fuels, including biomass, waste to energy, and coal.

"In these cases we have defined and validated with prospective customers, partners and third party subject matter experts, system requirements and related benefits.

"Our technology and technology demonstrations have been well received, and we are actively engaged in discussions and/or negotiations with prospective customers and partners -- many of them prominent global enterprises. We are determining how we can most effectively collaborate, in each of these categories, to advance and deploy ClearSign's technology in these high value market segments.

"We have added strength, depth and capacity to both our development team and our business development team, with the notable addition to our senior leadership team of Dr. Roberto Ruiz as Sr. VP Product Development.

"We have accomplished all of this with a small, but highly capable team and an operating budget that is, we believe, very modest when compared against the far-reaching market potential of our technology. We are well positioned to continue with this record of progress as we advance our technology and pursue the formation of key partnering relationships that will set the stage for successful market entry."
