<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We are a development stage company that designs
and develops technologies for combustion and emissions control with the aim of improving both the operating economics and environmental
performance of combustion systems.&nbsp;Our solutions are designed to be adapted into designs for both retrofit applications and
new designs. Our core technologies currently include Electrodynamic Combustion Control&trade; (ECC&trade;) and Duplex&trade; burner
technologies. Our ECC technology introduces a computer-controlled electric field into a combustion system in order to better control
gas-phase chemical reactions and improve system performance and cost-effectiveness. Our Duplex burner technology uses a unique
two-tier refractory tile configuration to reduce nitrogen oxide gas (NOx) emissions without the need for external flue gas recirculation,
selective catalytic reduction, or higher excess air operation. To date, our operations have been funded primarily through sales
of our common stock. We have earned no significant revenue since inception on January 23, 2008.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We believe that our technology may allow
prospective customers to benefit from substantially reduced costs associated with the construction (including refurbishment and
upgrade), operation and maintenance of these combustion systems, as compared to combustion systems that use no or alternative technology
to enhance combustion and control emissions through control of the flame. We also believe that our technology could improve emissions
control performance to meet regulatory standards while yielding a significant increase in energy efficiency and a decrease in the
cost of compliance with those standards. We believe these features enable our technology to minimize harmful emissions while maximizing
system efficiency.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">The combustion and emissions control markets
are significant, both in the wide array of industries in which the systems are used and in the amount of money spent in installing
and upgrading systems. Nearly two-thirds of the world&rsquo;s total energy consumption is accounted for by combustion of hydrocarbon
and other fuels in boilers, furnaces, kilns and turbines. These are used to generate electrical power, to provide heat for all
manner of industrial processes and for building heat and produce more than 50 quadrillion British thermal units (BTUs) of energy
annually in the U.S. In order to maximize energy efficiency while keeping pace with regulatory guidelines for air pollution emissions,
operators of these systems are continually installing, maintaining and upgrading a variety of costly process control, air pollution
control and monitoring systems. In its November 2013 analysis, The McIlvaine Company projected that $44 billion will be invested
globally in 2014 in equipment, instrumentation, and consumables to reduce air pollution. In April 2013, Filtration+Separation magazine
estimated the 2014 NOx control technology market, a sub-market of the pollution control market, to be $11 billion of which $2 billion
related to non-utility (e.g. commercial and industrial boiler) applications. Our current target market segments involve petroleum
refining and petrochemical processing, packaged boilers, and industrial solid fuel combustors.</P>

deployed our technology and our technology has not been tested or verified by any independent third party, we believe that if the
results we have observed in our laboratory testing can be replicated on a commercial scale, our proprietary technology platform
may improve energy efficiency, fuel flexibility and environmental performance for most types of industrial and commercial combustion
systems. Based on the results of our laboratory testing, we believe our technology compares favorably with current industry-standard
air pollution control and efficiency technologies, such as electrostatic precipitators, fabric filters, selective catalytic reduction
devices, low- and ultra-low NOx burners (which address nitrogen oxides), excess air systems and other similar technologies. Such
systems account for the majority of combustion energy utilization globally, and are used in:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt"><I>Technical requirements. </I>Our
ECC technology consists, in its simplest form, of four major components: (a) a computer, (b) standard software delivering proprietary
algorithms to (c) a power amplifier (resident outside the combustion chamber) and (d) electrode(s) (inside the combustion chamber).
The electrodes are optimized in material and shape to best suit the specific geometry of a given installation. We have also demonstrated
a technique to apply ECC to a combustion system without requiring an electrode to have physical contact with the flame.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">Our Duplex burner technology consists of
a lower-story tile, an upper-story tile, and fuel nozzles. When the fuel is directed to the lower story tile, the resulting hot
gas recirculating there anchors the flame. Once the furnace reaches its operating temperature, the fuel is anchored to the upper-story
tile. <FONT STYLE="color: #2A2A2A">This dramatically reduces&nbsp;NO<I>x</I> by greatly increasing the amount of entrained flue
gas to dilute NO<I>x</I>-forming species without any external fans or power. The greater entrainment also provides more thorough
mixing of fuel and air and shorter flames.</FONT> More thorough mixing of gases homogenizes the combustion zone and reduces peak
flame temperatures which cause NOx formation. A shorter flame allows for improved heat transfer and operation at a higher capacity
since it reduces the possibility of flame impingement and coking in a combustion chamber.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">Because the basic components of both systems
are available &lsquo;off the shelf&rsquo;, or require manufacturing techniques that are well within the current state of the art,
we do not depend on technology external to the Company that has not yet been developed.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We believe our technology can be retrofitted
to existing combustion systems to improve their performance and has the potential to provide substantial savings in both capital
and operating costs, or, for new-builds, can serve as the basis for fundamental improvements in the design, cost and operation
of combustion systems. We believe the economic gain realized by an operator could be significant in both reduced capital expenditures
and savings in annual operating and maintenance costs (including reductions in those costs associated with fuel consumption and
emissions).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The gain in energy efficiency that we expect
our technology to provide in boilers, solid fuel burners, refinery heaters, and other combustion systems stems in part from our
ability to precisely control the flow of hot gases within a gas volume. In most cases, efficiency is increased by increasing heat
flux onto targeted surfaces and reducing heat loss from other surfaces. Additionally, because the formation of pollutants is greatly
reduced at the source, the &lsquo;load&rsquo; placed on downstream pollution control equipment is also reduced, which we believe
could reduce both capital and operating expenses and improve financial return on investment for system operators.</P>

a high degree of risk. Please see the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K, which are incorporated
by reference in this prospectus, and those additional risk factors set forth below. Before making an investment decision, you should
carefully consider these risks as well as other information we include or incorporate by reference in this prospectus. The risks
and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us
may also affect our business operations. These risks could materially affect our business, results of operations or financial condition
and cause the value of our securities to decline.</I></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">We intend to form research and development
partnerships to develop our technology within targeted segments. Collaborative arrangements involve risks that participating parties
may disagree on business decisions and strategies. These disagreements could result in delays, additional costs, risks of litigation,
and failure of the development of our technology within the partnership&rsquo;s combustion market segment. Success of any collaborative
arrangements we enter into will depend in part on whether our partners fulfill their contractual obligations satisfactorily. If
our partners fail to perform their contractual obligations satisfactorily, we may be unable to make the additional investments
or provide the added services that would be required to compensate for that failure. If we are unable to adequately address any
such performance issues, our reputation may be materially adversely affected and the customer may exercise its right to terminate
a joint project, exposing us to legal liability. Our inability to successfully maintain collaborative relationships, once we enter
into them, or to enter into new collaborative arrangements, could have a material adverse effect on our results of operations.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The negative environmental impacts of industrial
activity have given rise to significant environmental regulation in industrialized countries. These regulations are important incentives
in the adoption of technologies like ours. To the extent that environmental regulations in the United States and in other industrialized
countries are modified in the future, or even relaxed, our technology may not produce the results required, or may even be unnecessary,
to comply with the modified regulations. In that case, our business and results of operations would be materially adversely affected.</P>

of our common stock. Our net tangible book value per share represents our total tangible assets less total liabilities divided
by the number of shares of our common stock outstanding on September 30, 2013. Assuming that we issue all of the shares of our
common stock offered by us at the offering price of $8.00 per share, and after deducting the placement agents&rsquo; fees and estimated
offering expenses payable by us, our net tangible book value as of September 30, 2013 would have been approximately $9.35 million,
or $0.97 per share of our common stock. This amount represents an immediate increase in net tangible book value of $0.56 per share
to our existing shareholders and an immediate dilution in net tangible book value of $7.03 per share to new investors purchasing
shares of our common stock in this offering.</P>

or hypothecate these warrants or the securities underlying these warrants, nor will it engage in any hedging, short sale,
derivative, put or call transaction that would result in the effective economic disposition of these warrants or the
underlying securities for a period of 180 days after the effective date. In addition, the warrants provide for registration
rights upon request, in certain cases. The demand registration right provided will not be greater than five years from the
date of effectiveness in compliance with FINRA Rule 5110(f)(2)(H)(iv). The piggyback registration right provided will not be
greater than seven years from the effective date of the offering in compliance with FINRA Rule 5110(f)(2)(H)(v). We will bear
all fees and expenses attendant to registering the securities issuable on exercise of the warrants, other than underwriting
commissions incurred and payable by the holders. The exercise price and number of shares issuable upon exercise of the
warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary cash dividend or
our recapitalization, reorganization, merger or consolidation. However, the warrant exercise price or underlying shares will
not be adjusted for issuances of common stock at a price below the warrant exercise price.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We are a development stage company that designs
and develops technologies that aim to improve key performance characteristics of combustion systems including energy efficiency,
emissions control, fuel flexibility and overall cost effectiveness.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We believe that our Electrodynamic Combustion
Control&trade; (ECC&trade;) technology could allow customers to benefit from substantially reduced costs associated with the construction
(including refurbishment and upgrade), operation and maintenance of these systems, as compared to combustion systems that use currently
available technology. We also believe that our technology could improve emissions control performance and meet regulatory standards
while at the same time yielding a significant increase in energy efficiency, thereby substantially reducing the cost of compliance
with air quality regulations. Our technology introduces a computer-controlled electric field into the combustion zone to allow
for more precise control of flame shape and heat transfer. This same technique can also be used to modify the complex chemical
reactions that occur during combustion in order to minimize harmful emissions while maximizing system efficiency. We believe our
technology can be adapted to various fuel types and multiple system sizes and configurations, and can be deployed on both a retrofit
and new-build basis.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">Nearly two-thirds of the world&rsquo;s total
energy consumption is accounted for by combustion of hydrocarbon and other fuels in boilers, furnaces, kilns and turbines. These
are used to generate electrical power, to provide heat for all manner of industrial processes and for building heat and produce
more than 50 quadrillion British thermal units (BTUs) of energy annually in the U.S. In order to maximize energy efficiency while
keeping pace with regulatory guidelines for air pollution emissions, operators of these systems are continually installing, maintaining
and upgrading a variety of costly process control, air pollution control and monitoring systems. In its December 2012 analysis,
The McIlvaine Company projected that $44 billion will be invested globally in 2013 in equipment, instrumentation, and consumables
to reduce air pollution, representing a 26% increase over the 2012 total of $35 billion. &nbsp;</P>

has not been deployed commercially, nor has it been tested or verified by any independent third party, if the results we have observed
in our laboratory testing can be replicated&nbsp;on a commercial scale, we believe our proprietary technology platform may increase
energy efficiency and improve fuel flexibility and environmental performance for most types of industrial and commercial combustion
systems.&nbsp;&nbsp;We believe our technology could compare favorably with current industry-standard air pollution control and
efficiency technologies including electrostatic precipitators, fabric filters, selective catalytic reduction devices, low- and
ultra-low NOx burners (which address nitrogen oxides), excess air systems and other such technologies. Such systems account for
the majority of combustion energy utilization globally. These include:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt"><I>Technical requirements.&nbsp;</I>Our technology
consists, in its simplest form, of four major components: (a) a computer, (b) standard software delivering proprietary algorithms
to (c) a power amplifier (resident outside the combustion chamber) and (d) electrode(s) (inside the combustion chamber). The electrodes
are optimized in material and shape to best suit the specific geometry of a given installation. We have also demonstrated a technique
to apply ECC to a combustion system without requiring an electrode to have physical contact with the flame. Because the system&rsquo;s
basic components are available &lsquo;off the shelf&rsquo;, or require manufacturing techniques that are well within the current
state of the art, we do not depend on technology external to the Company that has not yet been developed.&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 45pt">We believe our technology can be retrofitted
to existing combustion systems to improve their performance and has the potential to provide substantial savings in both capital
and operating costs, or, for new-builds, can serve as the basis for fundamental improvements in the design, cost and operation
of combustion systems. We believe the economic gain realized by an operator could be significant in both reduced capital expenditures
and savings in annual operating and maintenance costs (including reductions in those costs associated with fuel consumption and
emissions).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The gain in energy efficiency provided by
our technology in boilers, kilns, furnaces and turbines stems in part from our ability to precisely control the flow of hot gases
within a gas volume. In most cases, efficiency is increased by increasing heat flux onto targeted surfaces and reducing heat loss
from other surfaces. Additionally, because the formation of pollutants is greatly reduced at the source, the &lsquo;load&rsquo;
placed on downstream pollution control equipment is also reduced, lowering both capital and operating expense and yielding a positive
return on investment for system operators.</P>

documents include provisions that may have the effect of discouraging, delaying or preventing a change in control or an unsolicited
acquisition proposal that a shareholder might consider favorable, including a proposal that might result in the payment of a premium
over the market price for the shares held by our shareholders. Certain of these provisions are summarized in the following paragraphs.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"><I>Effects of authorized but unissued common
stock and blank check preferred stock.&nbsp;</I>One of the effects of the existence of authorized but unissued common stock and
undesignated preferred stock may be to enable our board of directors to make more difficult or to discourage an attempt to obtain
control of our Company by means of a merger, tender offer, proxy contest or otherwise, and thereby to protect the continuity of
management. If, in the due exercise of its fiduciary obligations, the board of directors were to determine that a takeover proposal
was not in our best interest, such shares could be issued by the board of directors without shareholder approval in one or more
transactions that might prevent or render more difficult or costly the completion of the takeover transaction by diluting the voting
or other rights of the proposed acquirer or insurgent shareholder group, by putting a substantial voting block in institutional
or other hands that might undertake to support the position of the incumbent board of directors, by effecting an acquisition that
might complicate or preclude the takeover, or otherwise.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">In addition, our articles of incorporation
grant our board of directors broad power to establish the rights and preferences of authorized and unissued shares of preferred
stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to
holders of shares of common stock. The issuance also may adversely affect the rights and powers, including voting rights, of those
holders and may have the effect of delaying, deterring or preventing a change in control of our Company.</P>

issued to MDB Capital Group LLC (&ldquo;MDB&rdquo;) in partial compensation for services rendered to us by MDB in connection with
a private offering we undertook in April 2011. MDB subsequently transferred warrants covering 62,050 shares of our common stock
to its employees. The warrants include piggy-back registration rights, which the MDB Selling Shareholders have exercised. Within
the past three years, MDB has provided underwriting and investment banking services, consulting services, and intellectual property
services described in previously filed periodic reports, proxy statements and other information with the SEC.</P>
