       Contracts for Two Existing Refined Coal Facilities Restructured

Business Wire

HIGHLANDS RANCH, Colo. -- March 12, 2013

ADA-ES, Inc. (NASDAQ:ADES) (“ADA” or the “Company”) today announced amendments
to the leases between its Clean Coal Solutions (CCS) joint venture and an
affiliate of Goldman Sachs (“Goldman”) for the two longest operating Refined
Coal (RC) facilities.

CCS and Goldman have amended the leases for the two longest operating RC
facilities to change the structure and timing of the lease payments. The
payments will be paid quarterly in advance and subject to adjustments for
inflation. Each lease has an initial non-cancellable term of two years and
will automatically renew, unless terminated at the option of the lessee
thereof, for successive one-year terms through November 9, 2021 and December
10, 2021, as applicable. Revenues to CCS are expected to remain at similar
levels as seen under the prior agreements.

Commenting on the outlook for the RC business, Dr. Michael D. Durham,
President and CEO, said, “With the restructuring of these agreements and our
recent closing of a RC facility with a third financial investor, our RC
business is back on track after several months of delays. We expect that the
recent resumption of the issuance of Private Letter Rulings for Section 45 RC
requests will assist with timely closing of contracts for a number of
additional RC facilities throughout this year and into 2014."
