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 Two Significant Avenues of Growth: Activated Carbon Injection (“ACI”) is deemed best available control technology for the removal of mercury from flue gas streams ADA is a current market leader for ACI equipment and engineering services Existing regulations create $200-400 million activated carbon (“AC”) market Responses to Court rulings likely to lead to $1 billion market for AC ADA has started construction of the largest, most efficient AC manufacturing facility in North America Developing capture technology for greenhouse gas CO 2 Recently started work under $3.2 million DOE and utility funded program to develop new technology Federal funding expected to increase to >$1 billion/yr Mercury Control CO 2 Control

-5- GROWTH AREA #1: Mercury Control

-6- Business Plan in Action for Mercury Control Stage 1: ADA demonstrated ACI with $80 million from DOE and leading utilities: Regulations followed. Stage 2: After market was created by regulations, ADA became a leader in the sale of ACI equipment: approximately $1 million per boiler. Stage 3: Provide AC to utilities for a continuous revenue source: approximately $2 million per year per boiler. 2009-10: Building AC production line; sourcing AC from third parties for treating, storing and selling to utilities. 2010: Activated Carbon Production Line commences operations.

-7- AC Market Drivers: Regulations for Mercury Control Existing rules create $200 - 400 million AC market State with proposed legis/regs more strict than CAMR (13) State with firm legis/regs more strict than CAMR (13) Planned plant that has ordered mercury control system Plant with consent decree limiting mercury emissions P P State currently accepting CAMR (24) P P P P P P P P P Total Existing Coal-Fired Capacity MW 24,000 12,000 2,400
