-3- Clean Coal Technology Coal is an abundant, cheap, and secure fuel that provides over 50% of electricity in the US 1,100+ coal-fired boilers in the U.S. ADA provides the technology to burn it cleaner Senior staff are industry recognized experts – 30-year track record of developing and then commercializing technologies Positioned to take advantage of public and political support for Clean Coal technologies

-4- Investment Highlights Developing solid sorbent capture technology for greenhouse gas CO2 Started work under $3.2 MM DOE and utility funded program Proposal submitted for $14 MM scale-up funding Supported by major power generating companies CO 2 Capture Emission Control Patented technology designed to improve combustion of PRB Coals in Cyclone boilers while reducing emissions of mercury and NOx Clean Coal Solutions installed two production facilities in December 2009 capable of producing over 6 MM tons of Refined Coal per year Tests completed to qualify for Section 45 IRS tax credit of $6.20/ton for ten years; before tax cash flow of ~$1 per ton to ADA-ES; monetization also triggers payments to ADA-ES of up to $4 MM from JV partner, NexGen Congress considering one year extension to allow placement of additional units to qualify for the tax credits Activated Carbon Injection (“ACI”) is deemed maximum achievable control technology (“MACT”) for the removal of mercury ADA is a market leader for ACI equipment and engineering services ADA Carbon Solutions (“ADA-CS”) building new energy-efficient AC manufacturing facility in LA; DOE awarded ADA-CS’ subsidiary, Red River Environmental Products, $245 MM conditional loan guarantee to finance the facility. EPA is developing three new MACT regulations expected to create $1 B market for AC ADA-CS is permitting for up to 5 additional AC production plants. ADA has the rights to own up to 50% through equity contribution in additional capacity Refined Coal

GROWTH AREA #1: Refined Coal Product ADA-ES’ opportunity through joint venture with an affiliate of NexGen Resources Corporation -5-

Section 45 Refined Coal Tax Credit Clean Coal’s patented refined coal technology, CyClean, is designed to enhance combustion of PRB coals in cyclone boilers Two systems placed-in-service in December, meeting Section 45 tax credit deadline for – $6.20 ton/coal (escalates annually) for ten years – Together, facilities are expected to produce greater than 6 MM tons of Refined Coal per year – Reduced NO x by >20% and Hg by >40% Monetized revenue expected to produce > $6 MM in operating income per year for ADA-ES Except upfront payment of ~$4.5 MM per facility Monetization will trigger up to $4 MM from NexGen to maintain its 50% of JV Working to obtain extension of the placed-in-service deadline for another year to expand business further in 2010 – If extended, an additional 10-20 MM tons could be placed in service -6-

-7- GROWTH AREA #2: Emission Control

-8- AC Market Drivers: Regulations for Mercury Control Green states with existing rules create $200 - 300 MM AC market

ADA Commercial ACI Systems > 20 GW ADA Commercial ACI Systems > 20 GW Plant burns PRB coal or lignite Plant burns bituminous coal ADA-ES Clients -9-

-10- Expected Federal Laws that Will Increase Our Markets U.S. EPA MACT for Coal-Fired Boilers – Will cover all 187 Hazardous Air Pollutants (“HAPs”) – Should result in 90% to 95% limit for mercury – Final regulations expected November 2011; 3 years to implement U.S. EPA Industrial Boiler MACT – Will cover larger number of boilers, smaller units – Draft published April 29 ; to be finalized by December 2010 U.S. EPA MACT for Cement – AC needed for both mercury and volatiles – Draft expected this month U.S. Legislation – 3-P Bill could be added to Climate bill by Sen. Carper (D-DE) which includes 90% Hg Canadian-wide mercury standard has been passed th

AC Production Supply / Demand ADA -CS -12-

ADA-CS New AC Production Built largest AC plant in the U.S. to date: 150 MM lbs/yr Plant designed to be low-cost producer 3-5 year development process: Startup activities commenced in May 2010 Site permitted for 2 nd production line Progress on permits for 4 additional lines in North Dakota -13-

-14- Low-Cost Producer Plant sited in the middle of lignite reserves – Provides access to a long term supply of low-cost feedstock material Minimal transportation costs for lignite Plant design with four furnaces in a single production line minimizes labor requirements Modern, state-of-the-art equipment reduces maintenance costs Production designed for large volume customers, minimizes material handling and labor Energy efficient design with extensive energy recovery – Generates 19 MWs, 6 MW for internal use, 13 MWs to be sold on grid as revenue source

GROWTH AREA #3: Control of Greenhouse Emissions: Carbon Dioxide -15-

ADA-ES CO 2 Capture Technology Designed to capture CO 2 from flue gas in conventional coal- fired boilers Based on regenerable solid sorbents - advantages over competing technologies: – For the customer: lower cost and less parasitic energy – For ADA: continuous revenues from sale of proprietary chemical sorbents $3.2 MM DOE R&D program with extensive industry support – Southern Company, Luminant, American Electric Power, Xcel Energy There has been a significant increase in funding opportunities for CCS technology through DOE -16-

Next Steps for CCS Technology Current DOE Program through 2010 – Field tests using slipstream device • Currently testing on Lignite at Luminant • Bituminous Coal at Southern Company • PRB at Xcel – Design of conceptual 500 MW system Responded in December to a DOE Funding Opportunity Announcement for scale-up of solid-sorbent based carbon capture technology – $14MM proposal being evaluated Opportunities for DOE and industry funding for full-scale demonstrations are expected in the future -17-
