CO2 CAPTURE: OVERVIEW

Developing proprietary solid sorbent capture technology to capture CO2 from flue gas in conventional coal-fired boilers DOE and industry funding:

- Phase I—$3.8 M R&D at 1 KW pilot plant completed in 2011

- Phase II—$20.5 M, 51-month contract to scale-up technology to 1 MW

• Entered Fabrication and Construction phase of 1 MW plant in June 2012, estimated completion in October

2013

• Testing in 2014

Advantages over competing technologies:

- For customer: lower cost and less parasitic energy

- For ADA: continuous revenues from sale of proprietary chemical sorbents

NON-GAAP FINANCIAL MEASURES

Adjusted gross margin and adjusted gross margin percentage exclude coal sales and raw coal purchases and retained tonnage operating expenses. Adjusted gross margin and adjusted gross margin percentage are non-GAAP financial measures which are used to provide investors with greater transparency with respect to the effect on gross margin from Clean Coal’s operation of certain RC facilities for its own account. We believe these non-GAAP financial measures provide meaningful supplemental information for investors regarding the performance of our business and the effect on gross margin and gross percentage of the operation of these RC facilities by Clean Coal for its own account.
