GROWTH AREA #3: Refined Coal Product ADA-ES’ opportunity through joint venture with an affiliate of NexGen Resources Corporation -32-

Clean Coal Solutions LLC ADA Joint Venture Clean Coal’s patented refined coal technology, CyClean, is designed to enhance combustion of PRB coals in cyclone boilers It produces significant benefits to the customer: – Reduces NOx and mercury emission – Greater PRB fuel flexibility – Enhanced operability – Decreased demand for activated carbon Customer can share up to half of the $6/ton tax credit for qualified product Equipment is simple to fabricate and install – Capital investment approximately $800k per site – Fabrication and installation 3-5 months -33-

Section 45 Refined Coal Tax Credit Tax credit incentive – $6 ton/coal for ten years – Example for 500 MW plant: 2 mm tons/yr will create a tax credit of $12 million per year for 10 years Tax credit qualifications – Placed in service by January 1, 2010 – Owned and operated by third party – Reduces NOx by 20% – Reduces Hg by 40% IRS will provide guidance on certification and compliance – Final guidance has been delayed a number of times Window may be open for an extension -34-

Opportunities and Challenges for CyClean Opportunity – Attempting to get two facilities installed before year-end – Produce >$3-6 million in earnings for ten years – $4 million due from NexGen to maintain 50% of JV Challenges – Equipment must be fabricated and installed by year-end – Approximately $1 million in JV capital expenditures – Waiting for explicit guidance from IRS – Permits required prior to installation – Complicated contracts with utility partners must be completed for each facility – Agreements with monetizers must be secured -35-

Lawsuits Calgon – Suit based upon a contract Calgon signed with MidWest Generation for AC sales – Calgon and ADA had an MOU that provided a commission on sales of AC bid while the MOU was in place – ADA believes that it is owed >$8 million in commissions on this contract – Discovery near complete, trial expected in Q2-Q3 2010 Norit – In June, Norit tried to get an injunction to stop construction of the plant. This was summarily rejected by the Judge. – On October 6, the Judge ruled in favor of a motion ADA filed requiring that the suit be addressed by mandatory arbitration in Atlanta, GA. • We view this as a very positive development in the Case -36-
