PART I

Item 1. Description of Business

This Annual Report may contain forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933. In particular, such forward-looking
statements may be found in this section under "Description of Business," and
below in Item 6. under "Management's Discussion and Analysis or Plan of
Operation ." Actual events or results could differ materially from those
discussed in the forward-looking statements as a result of various factors
including those set forth below or under the heading "Management's Discussion
and Analysis or Plan of Operation."

(a) Business Development.
ADA-ES, Inc. ("ADA-ES" or "Registrant" or "Company", which term includes its
wholly-owned subsidiary unless otherwise indicated) is an environmental
technology and specialty chemicals company helping electric utility companies
remain competitive while meeting environmental regulations. The major activities
of the Company include the sale of flue gas conditioning ("FGC") and other
chemicals and technologies for electric generating coal-fired boilers, and
testing and services related to the emerging market for mercury emission control
("MEC") for such boilers. ADA-ES was incorporated under the laws of the State of
Colorado in 1997 to serve as the holding company for ADA-ES, LLC. In May 1997,
Earth Sciences, Inc. ("ESI" or "Earth Sciences") acquired a 51% equity position
in ADA-ES, LLC through a combination of stock and cash. The acquisition
agreement provided for payments of cash and notes and included an option for
Earth Sciences to acquire the remaining equity interests in ADA-ES, LLC from the
ADA-ES shareholders. In May 1998, Earth Sciences exercised that option,
acquiring a 100% interest in ADA-ES, LLC by issuance of 1,716,000 shares of
stock to the shareholders of ADA-ES in exchange for all their shares in ADA-ES.
As of January 1, 2003, Earth Sciences transferred all of its ownership in
ADA-ES, LLC into ADA-ES. In March 2003 ADA-ES and ESI entered into an agreement
for the pro rata distribution of all the common stock of ADA-ES to the
shareholders of ESI. The distribution occurred on September 12, 2003 based on a
record date of August 29, 2003 as set by the ESI Board of Directors. The
distribution resulted in ADA-ES being a separate company operated apart from
ESI.

During 2003, ADA-ES (a) maintained its FGC business through continued chemical
sales and service on four full-time units, one temporary unit and a
government-funded research and development contract for development of new FGC
products; (b) continued limited sales and further demonstrated a new
anti-slagging product through a joint venture with Arch Coal, Inc. ("Arch")
formed to co-market that product; and (c) substantially increased its MEC
business through government and industry funded contract work including existing
and new contracts and a growing number of commercial activities.

Thus far in 2004, ADA-ES is in the final phases of long-term testing of a
mercury emission control system at the Southern Company's Gaston plant in
Alabama under a contract awarded in the fall of 2002 and is actively making
preparations to participate in (1) a new 5-year government- and
industry-supported contract for permanent installation and evaluation of mercury
removal and related activities at another utility, and (2) a new 3-year
government and industry supported contract for testing of mercury emission
control systems at four different plants. Through the co-marketing agreement
with Arch, preparations are being made for a sixth utility demonstration of its
new anti-slagging chemical. These activities and those in the preceding
paragraph are described in the succeeding paragraphs below in Item 1(b).

ADA-ES currently has four operating FGC units at coal-fired utilities in Iowa,
Louisiana, Oregon, and Wisconsin. Revenues from sales of equipment and chemicals
to FGC customers in 2003 and other FGC contract work totaled $2,037,000.
Assuming the continuation of the historical levels of FGC chemical purchases
over the last four years by its existing customers, ADA-ES expects to recognize
revenues of approximately $2.0 million in 2004 from sales to those customers. In
addition, ADA-ES is in discussions with several utilities where it is believed
that the use of its FGC can aid operations and expects to add one more FGC
customer by 2005. There can be no assurances that either of those expectations
will be met.

Early in 2000, ADA-ES received the signed Department of Energy ("DOE")
cooperative agreement awarded to develop a broader spectrum of FGC chemicals
(the "DOE FGC Contract") and commenced research activities thereunder. In the
fall of 2000, ADA-ES received the award of an additional DOE cooperative
agreement to test mercury control technology (the "DOE Mercury Contract")
totaling up to $6.8 million over the life of the contract, which amount includes
industry cost-share, and commenced research activities thereunder. In the fall
of 2002 ADA-ES received the award of a further DOE cooperative agreement and



commenced activities thereunder for the long-term test of mercury control
technology totaling $2.4 million, which amount includes industry cost share.
During 2003 ADA-ES commenced limited work on the permanent installation, testing
and related activities of a mercury control system for We Energies Presque Isle
plant in northern Michigan. The contract for that work is expected to be signed
soon and will cover $10 million of work over a 5-year period. In the fall of
2003 ADA-ES received the award of a further DOE cooperative agreement and
commenced activities thereunder for the testing of mercury control technology at
four plant sites over the next 3 years totaling $8.8 million, which amount
includes industry cost share. Revenues recognized in 2003 from these
government/industry contracts totaled $2.7 million. ADA-ES retains the right to
commercialize any products developed under the activities of these contracts.
Assuming continued funding, ADA-ES expects to recognize revenues of
approximately $4.8 million from these contracts in 2004. The government commits
funds for these contracts on an annual basis and although continued funding
under the awarded contracts is considered highly probable, there can be no
assurances that the government will continue to approve such funding in its
future budgets.

In July 2001, ADA-ES entered an agreement with Arch, the second largest U.S.
coal producer, to jointly market ADA-249 to cyclone-fired power plants. The
agreement was modified and restated as of January 1, 2002. ADA-249 has been
demonstrated to improve the combustion performance of cost-efficient, low-sulfur
coals from the Powder River Basin (PRB) in cyclone boilers. When added prior to
combustion, this patent-pending product increases PRB coal's burning efficiency,
allowing it to perform more like bituminous coal. Utility companies using
ADA-249 may thus realize significant savings from reduced fuel costs, enhanced
operational flexibility and improved marketability of combustion byproducts.
Continuous feeding at one small unit, seasonal feeding at another unit and
demonstrations at three utilities took place during 2003 with positive results.
A larger scale test where ADA-249 will be blended with coal from Arch is
scheduled for the first quarter of 2004. We expect to add at least one
continuous user of ADA-249 in 2004. However, the election to install a system
for addition of ADA-249 and use it on a continuous basis is complex and involves
fuel buying and plant operating decisions, and there can be no assurances that
such expectation will be met.

The Spin-Off
In March 2003, ESI and ADA-ES entered into an agreement to provide for the
distribution of the ADA-ES stock to the shareholders of ESI. In an effort to
maximize stockholder value, the ESI Board of Directors decided to separate its
significant operations into two separate businesses. Since ESI no longer
produces the chemicals needed for the ADA-ES proprietary environmental products,
there is no longer a necessary business connection between the two companies.
The separation allows ESI to focus on its mineral exploration business, while
ADA-ES focuses on its environmental technology/specialty chemical business. The
distribution has resulted in two independent public companies.

The separation of the two businesses was accomplished through a spin-off of
ADA-ES, Inc. In the spin-off, 100% of the outstanding shares of ADA-ES common
stock held by ESI were distributed to the ESI shareholders on September 12,
2003. In the distribution, the ESI shareholders received one share of ADA-ES
common stock for every ten shares of ESI common stock they held on the close of
business on August 29,2003, the record date for the spin-off.

Sale of Stock and Debenture to Arch Coal, Inc.
The Company executed a Securities Subscription and Investment Agreement with
Arch Coal, Inc. ("Arch") in July 2003. The agreement provided for an investment
by Arch, which was subject to completion of the spin-off and certain other
conditions precedent, and could have been rescinded if the spin-off did not
occur.

Pursuant to the investment agreement, Arch purchased, in September 2003, a
$300,000 convertible debenture from the Company (the "Debenture"), with a term
of five years that bears a variable interest rate, currently 6%, based upon the
Wall Street Journal prime rate plus 1.75%. Interest accrues quarterly and is
payable with principle at the end of term. The Debenture is convertible into
shares of Common Stock of the Company after 2 years at the lower of a rate of
$20, $30, and $40 per share in the 3rd, 4th and 5th years, or 150% of the then
current market price. The Debenture is convertible solely at the discretion of
Arch. Collateral for the Debenture is the patent pending for the Company's
ADA-249 product and the Company's interest in the agreement with Arch to jointly
market the ADA-249 product discussed below under the heading "ADA-249."

In addition to the Debenture, and pursuant to the investment agreement, Arch
also purchased in September 2003, 137,741 shares of the Company's common stock,
for an aggregate purchase price of $1 million or $7.26 per share. The price per
share paid and the number of shares issued was based on a formula of ten times
200% of the 20 day average price of the Earth Sciences common stock before

                                       2


closing or $10 per share whatever was less. Of those issued, 37,741 shares have
been placed in escrow and a portion of those shares may be returned to the
Company at the end of one year depending on the future market price for the
Company's shares. If the market price per share for a 20-day period in the
following year is above $15, then all the shares in escrow will be returned to
the Company. At market prices per share between $9.08 and $15.00 per share a pro
rata portion of the stock placed in escrow will be returned to the Company. If
market prices above $9.08 per share are not reached for any 20-day period, all
of the shares placed in escrow will be released to Arch. As a part of the
purchase Arch was also granted an option to purchase 50,000 shares for $10.00
per share. The option expires in five years. Under the option, Arch may purchase
one third of the shares after one year, another one third of the shares after a
second year, and another one third of the shares after three years.

Arch has agreed not to sell or solicit the sale of any of the shares issued in
the above transactions for a one-year period. The Company has granted Arch
certain "piggyback" rights in the event the Company registers certain other
equity securities and certain demand registration rights as part of the
transaction. A designee of Arch has been appointed a seat on the Company's Board
of Directors and management of the Company has agreed in the future to nominate
and to vote all proxies and other shares of stock in the Company which they are
entitled to vote in favor of that designee so long as Arch holds no less 100,000
shares of the Company's common stock. Assuming (1) any shares placed in escrow
are released to Arch, (2) Arch converts the Debenture at a rate of $10.65 per
share (150% of the market price at 12/31/03), and (3) Arch exercises its option
to purchase 50,000 shares, Arch would own a total of 215,910 shares or approx.
5.9% of all outstanding shares of the Company.

(b) Business of Issuer.

BUSINESS
Market for Our Products and Services
The primary drivers for many of our services are new environmental regulations
and the deregulation of the utility industry. Environmental regulations, such as
the 1990 Clean Air Act Amendments, various State regulations and permitting
requirements for new plants, are requiring utilities to reduce emission of
pollutants, such as sulfur dioxide and nitrogen dioxide, and toxic particles.
The Environmental Protection Agency and numerous state regulatory bodies are
developing regulations that are expected to require large mercury reductions at
the nation's 1,100-plus coal units by 2008. Early DOE studies indicate that the
cost to control these emissions will be $2-$5 billion annually. We are
positioning ourselves to be a key supplier of services to the market that is
anticipated to be established by these regulations. The markets that will be
affected by new regulations are the same ones that we currently operate within.
In addition, the systems and products that are required for mercury controls fit
well with our existing products and capabilities.

In addition to environmental regulations, the coal burning electric power
generation industry is also impacted by the ongoing deregulation of the utility
business. Historically, public utilities have been able to pass capital and
operating costs onto customers through rate adjustments. However with
deregulation, utility companies face competitive challenges requiring them to
better control capital spending and operating costs. These changes increase the
need for cost-effective retrofit technologies that can be used to enhance
existing plant equipment to meet the more stringent emission limits while
burning less expensive coals. We have entered this market with (1)our
proprietary non-toxic chemical conditioner that offers both technical and
economic advantages over the hazardous chemicals that have been in use, (2)
mercury control technology that has been demonstrated to effectively reduce
mercury emission over a broad range of plant configurations and coal types, and
(3) products, such as ADA-249, that provide utilities flexibility in choosing
the fuel they plan to burn.

In the unprecedented event that existing and expected environmental laws were
rescinded or substantially changed, our business would be adversely affected by
declining demand for such products and services. Demand for the Company's FGC
and ADA-249 products is primarily two-fold. Customers purchase these products to
mitigate operating problems and/or to help comply with environmental regulations
such as the Clean Air Act Amendments of 1990. Although the Company's existing
customers and those expected in the near-term are believed to desire the
Company's products for mitigation of operating problems, we would anticipate
that any softening of existing air pollution control requirements would slow
expected growth for these products. Demand for the Company's mercury emission
control technology is being driven almost exclusively by legislation requiring
such control. Although several states have passed, or are expected to pass,
legislation requiring such control (Connecticut, Massachusetts, New Hampshire,
New Jersey, North Carolina and Wisconsin), federal legislation mandating mercury

                                       3


control is expected to be debated this year as part of EPA's Proposed National
Emission Standards for Hazardous Air Pollutants (proposed rule published in the
Federal Register 1/30/04). EPA has stated in the rulemaking activity that it
intends to require reduction in the emission of mercury. Delays in, or
derailment of, the passage of federal mercury control legislation will
significantly impede the expected growth of the Company.

The environmental technology/specialty chemicals industry is generally subject
to seasonal trends. These trends reflect the general pattern of electricity use
and generation, which typically peak during the spring and summer months and
decline from October through March. Our quarterly results can be expected to
fluctuate in the future, reflecting this seasonality. These and other factors
may make it difficult to predict our results of operations. If our results of
operations do not meet the expectations of our stockholders and financial
analysts, then our common stock price may be adversely impacted.

Government and Industry Supported Contracts
In 2003, 2002 and 2001, 45%, 47% and 46%, respectively of the Company's revenues
were derived from or related to DOE and industry-supported programs. Our
revenues from government and industry-supported contracts would be adversely
impacted by any material decrease in funding for the projects in which we are
involved. In addition, we look to the DOE funding as a significant means to
further develop our technology and intellectual property in the area of mercury
emissions control covered by that funding. Any material decrease in funding for
the projects in which we are involved would hamper the development of our
technology and intellectual property as it does not appear that we could
currently fund the same level of development work apart from the support
provided by DOE and industry.

The DOE issues solicitations from time to time for various development and
demonstration projects. The DOE solicitations range in subject matter, and the
Company submits bids for topics that fit the Company's mission and strategic
plan. The bids involve a proposed statement of work, and contracts are
negotiated with successful bidders to perform the specified work. The contracts
with the DOE are known as Cooperative Agreements and are considered financial
assistance awards. The Company currently has three such agreements. Generally,
the agreements cover the development and/or demonstration of air pollution
control technologies for coal-fired power generating plants. Our agreements
cover the testing of mercury control systems at power plants. The work may
involve designing and fabricating equipment, installing the equipment at power
plants, testing the equipment, preparing economic studies, and preparing various
reports. The deliverables required by the agreements include various technical
and financial reports that are submitted by the Company on a prescribed
schedule. The agreements require that the negotiated scope of work be performed,
which includes testing/demonstrating various air pollution control technologies.
The agreements with the DOE provide that any intellectual property that results
from the work become the property of the Company.

The agreements with DOE generally require industry cost share, which is
considered a key component to the viability of the project and which may take
the form of cash contributions and/or in-kind contributions of material and
services. The cost share percentages on the mercury projects in which we are
involved range from 32% to 50%. Typically, the utility host site for the
demonstration project provides a considerable amount of the cost share with
other interested industry partners also providing funding, either individually
or through EPRI (the Electric Power Research Institute). To the extent that the
required cost share is not provided by industry partners or EPRI, ADA-ES
provides the balance by reducing the revenues it would otherwise recognize on
the work performed. We expect the power industry's interest in these and future
projects to continue and grow as the nation moves closer to enactment of mercury
control regulations.

Key Business Relationships
We have developed key industry relationships with companies much larger than
ourselves (e.g. NORIT Americas, Inc., ALSTOM Power, Inc., and Arch Coal, Inc.).
Subject to the terms of those agreements, the relationships may be terminated by
the passage of time, through notification from the other party or failure of the
Company to obtain a certain market share of activated carbon sales. Those
relationships are expected to bolster the premier position we believe we hold
that will allow participation in the large market projected to emerge from the
anticipated forthcoming regulations to limit mercury emissions from coal burning
power plants. The loss of those key relationships would impede our ability to
secure the highest achievable amount of business from that emerging mercury
control market. (See the discussion below under the caption "ADA-249" and
"Commercial Mercury Emissions Control.)

                                       4


ADA-ES' Technology and Services - FGC
We have developed a technology for conditioning flue gas streams from combustion
sources that allows existing air pollution control devices to operate more
efficiently. Through various suppliers and contractors, we may manufacture
engineered units for each individual application. The units mix, pump and
monitor the feed of proprietary chemical blends. The chemical blends are applied
to the flue gas streams by a pressurized system of specially designed lances and
nozzles. Such treatment of the flue gas stream alters the physical properties of
the fly ash particles contained therein primarily by decreasing particle
resistivity. This alteration allows the existing electrostatic precipitator
("ESP") to more effectively collect such fly ash particles that would otherwise
escape into the atmosphere. ADA-ES' technology also has application in the
cement and petroleum refining industries where particulate emissions are being
or need to be controlled. The non-utility markets are not being aggressively
pursued since the profit margin potential for such customers is considered to be
less since chemical usage is lower.

DOE FGC Contract
In September 1999, ADA-ES was awarded a $1 million DOE cooperative agreement to
develop an expanded line of flue gas conditioning agents. This project was
initiated in January 2000 with an objective of developing a new family of flue
gas conditioning products. These products are targeted for use at coal-fired
power stations that are equipped with older and smaller cold-side electrostatic
precipitators. Efforts during the first year helped to establish laboratory
methodologies for evaluating trial formulations of chemical additives, preparing
and evaluating trial quantities of additives, and beginning full-scale field
trials of the most promising formulations. Three of the best performing
conditioning agents were tested at full scale at the City of Ames power plant,
and one showed improved performance when compared to the product currently being
used at the plant. Refinements were made to the conditioning agents during 2001
and field trials began late in the year at a PacifiCorp plant. The testing at
PacifiCorp was successfully completed during 2002 showing opacity reductions. In
addition, no detrimental impacts on ash quality were observed. A third test
series was begun later in the year at the AEP Conesville Plant. Initial results
showed positive performance of the product in terms of opacity reductions. The
testing continued during 2003. A final series of tests were completed at the We
Energies Presque Isle plant in 2003 and the cooperative agreement with DOE was
completed late in the year. Commercial flue gas conditioning products may result
from this work that will serve a new market segment of power plants for ADA-ES.
Under terms of the cooperative agreement with the Department of Energy, ADA-ES
will own the proprietary rights to any commercial products that are developed as
a result of this work. ADA-ES has provided the 20% cost share for this project.

ADA-249
In 2000, we introduced a new specialty chemical, ADA-249, a product designed to
save utility companies with cyclone furnaces significant costs each year through
reduced fuel costs, enhanced operational flexibility and improved marketability
of combustion by-products. Cyclone furnaces were designed as an efficient,
compact way to burn high-ash, high-sulfur coals to produce steam for power
generation. The coals for which these units were designed typically produce a
thick molten slag layer on the walls of each cyclone barrel. The slag coating
catches the incoming coal and holds it until combustion is completed. When
switching to Powder River Basin ("PRB") coal, however, the slag layer is usually
too thin and watery to capture the coal, so the coal must burn in flight. Even
though PRB coal burns faster than bituminous coal, there is just not enough time
for combustion to be completed within the main furnace firebox. The result is
usually unacceptable amounts of unburned carbon in the flyash as well as
increased ash deposition, increased air emissions, and an unfavorable unit heat
rate. Another problem with PRB coal slag in a cyclone furnace is that it
solidifies (freezes) abruptly during low-load operation when the cyclone
temperature drops.

Since these boilers rely on keeping the slag molten all the way to the slag tap
(a drain on the furnace floor) in order to operate, the freezing problem can
cause unplanned shutdowns and lost revenues. In order to keep the PRB coal slag
molten, these units must be operated at high loads even during periods of low
demand, which adversely affects power revenues. Finally, bottom ash is a more
valuable commodity for sale to ash brokers than flyash. Many cyclone boilers
that have converted to PRB coal have lost significant revenues from ash sales
compared to the old days of burning high-ash coals.

ADA-249 is a patent-pending product designed to modify slag viscosity. ADA-249
is a blend of iron oxides, mineralizers, and flow enhancers, that is added to
the PRB coal prior to combustion in order to create the proper slag layer for
combustion within the cyclone barrel. In application at the utility, ADA-249 is
conveyed mechanically from a supply delivered via dump truck to a hopper. From
there ADA-249 is fed by screw and belt conveyors to the coal feeders. The
addition of ADA-249 to the coal results in more coal burning in the cyclone,
less carbon in the flyash, better precipitator performance, reliable slag
tapping, and more bottom ash to sell. We design and sell the delivery system and
the continuing supply of chemical.

                                       5


In May 2001, we entered into an agreement with Arch Coal Inc., the second
largest U.S. coal producer, to jointly market ADA-249 to cyclone-fired power
plants. The agreement was modified and restated as of January 1, 2002. Pursuant
to the agreement, the Company has granted a non-exclusive, non-transferable
license to the joint venture ("JV") to use ADA-249 in connection with the JV
activities. The JV is controlled by a five-member management committee, three of
whose members are selected by Arch and the remaining members by the Company. The
JV will pay the Company from the commercial price less a discount of
approximately $15 per ton for all ADA-249 material supplied and commercial rates
for any technical services. The Company and Arch each will bear their own costs
and expenses related to any ADA-249 marketing efforts. Arch will fund the JV
activities, including equipment needs and will retain any net profits. Either
party may terminate the JV upon 60-days written notice after non-approval of the
annually required business plan.

Together, we and Arch anticipate providing to Arch customers a long-term package
of PRB coal, the ADA-249 chemical and, if needed, the required injection
equipment. This package is intended to enable boiler operators to achieve the
benefits of the ADA-249 fuel additive without making a significant capital
investment. The companies will also handle the logistics of supply and system
maintenance. During 2003, in addition to continual sales to one customer and
seasonal sales to another, (the revenues from whom amounted to less than 10% of
the Company's total revenues), ADA-249 was demonstrated at three sites, for
which we are in various stages of negotiation to supply ADA-249 on a continual
basis. The DOE does not participate with the Company in any of its activities
related to ADA-249.

DOE Mercury Contract
ADA-ES began work on a cooperative agreement with the Department of Energy in
October, 2000 to demonstrate full-scale mercury control systems at coal-fired
power plants. During the three-year, $6.8 million project, integrated control
systems were installed and tested at four power plants. The mercury control
system involves injecting powdered activated carbon (PAC) into the power plant
flue gas where it ties up the mercury. The existing particle control equipment
at the power plant then collects the PAC. ADA-ES was responsible for managing
the project including engineering, testing, economic analysis, and information
dissemination functions. Power generating companies that entered into contracts
with ADA-ES are Alabama Power Company, We Energies, and PG&E National Energy
Group. During 2001 ADA-ES completed demonstration tests at two of the plants,
and the remaining two plants were tested during 2002. The first test site was
Alabama Power's Gaston plant, which uses fabric filters to reduce particulate
matter emissions. Tests using PAC at this site showed that 80-85 percent of the
mercury was removed, with as much as 90 percent being removed at the highest
performing periods during two weeks of testing. The We Energies Pleasant Prairie
Power Plant was the second site to be tested. This site is equipped with
electrostatic precipitators for particle collection. Mercury-removal rates at
this site using PAC ranged from 40 to 60 percent, with short-term peak removal
rates being 60-70 percent. Testing at the PG&E Brayton Point Station showed that
mercury removals of 90 percent could be achieved using PAC. Test data from Salem
Harbor were still being evaluated at the end of 2003 and were not available for
release. The Cooperative Agreement with DOE is scheduled to be completed in
mid-2004. Overall industry cost share on this project is 33% and ADA-ES has
provided cost share of approximately 13% of the total project.

DOE Long-Term Test of Mercury Controls
ADA-ES was awarded a $2.4 million cooperative agreement from the Department of
Energy in September 2002 to install a mercury control system and evaluate its
operation over an extended period of time. The project location is Alabama Power
Company's Plant Gaston where PAC has been injected into the flue gas stream
between an existing electrostatic precipitator and COHPAC baghouse. A limited
test of this configuration was performed under the DOE project described above
with good results. The extended test will mature the technology and provide
information that is needed to assure reliable long-term continuous operation in
these systems. Work on the project in 2003 involved installation and several
test regimes. Further testing and final reporting on results of the project is
expected in mid-2004. Overall industry cost share on this project is 43% and
ADA-ES has provided cost share of approximately 18% of the total project.

CCPI Program at We Energies
The Company has been selected to provide mercury control technology and services
for a major project at the We Energies Presque Isle Power Plant. The U.S.
Department of Energy announced in January 2003 that it will award a grant to We
Energies, located in Milwaukee, Wis., to demonstrate an integrated mercury and
particulate matter emissions control system on three generating units at the
facility located in Marquette, Mich. The demonstration project, named TOXECON,

                                       6


will also investigate the capabilities of the proposed system to control sulfur
dioxide and nitrogen oxide emissions. The primary attribute of TOXECON, an EPRI
(Electric Power Research Institute) patented process, is that it potentially
represents the best option for control of greater than 80 percent of mercury
from coal-fired plants. TOXECON may also prove to be the primary mercury control
choice for western coals, and the only choice for units with hot-side
electrostatic precipitators. TOXECON will make use of only one "baghouse," or
emissions collection structure, for three small boilers, increasing the
cost-effectiveness of the integrated system. TOXECON would also allow for
separate treatment or disposal of the ash collected in the primary particulate
control device, and would be applicable to a significant number of existing
coal-fired plants in the U.S. Specific objectives of the project are to achieve
at least 90 percent mercury removal; determine viability of sorbent injection
for up to 70 percent sulfur dioxide control; minimize waste disposal with a
target of 100 percent utilization; and recover at least 90 percent of the
mercury captured in the ash. DOE will provide $25 million of the project's $50
million total cost. We Energies will host the project as well as serve as the
prime contractor with the DOE. The Company is expected to provide on-site
engineering support, mercury control and measurement technologies, and project
reporting services under a $10 million contract with We Energies. Cummins &
Barnard will provide design construction management resources to the project.
The formal contract is expected to be executed in the first quarter of 2004.
Overall industry cost share on this project is 50% and ADA-ES is not providing
any cost share to the total project.

Work under the contract will cover five phases over a five-year period , with
design and construction expected to begin during 2004. As a result of the
project, it's expected that there will be (i) a significant reduction in the
rate of air emissions from the Presque Isle units and (ii) mercury control
retrofit technologies and emissions control improvements applicable throughout
the U.S.

CCPI Program at Sunflower, AEP, Ameren UE and Ontario Power
During 2003 the Company was awarded an $8.8 million cooperative agreement with
the U.S. Department of Energy's National Energy Technology Laboratory
(DOE/NETL). The agreement is to perform longer-term sorbent-based mercury
control technology testing for coal-fired power plants. The project will be
executed together with ADA-ES' partner, ALSTOM Environmental Control Systems
("ALSTOM"), one of the largest suppliers of air pollution control equipment to
power plants in North America. The program will be carried out over 3 years.

Under the new program, ADA-ES and ALSTOM will test the mercury control
technology for much longer periods of time at four power plants. These will
cover a combination of coals and pollution control equipment configurations
typically used in over 900 plants, and more than 75% of the U.S. coal-fired
generating capacity. ADA-ES and ALSTOM will be working in partnership with
Sunflower Electric, American Electric Power, AmerenUE, and Ontario Power, which
are providing host sites. These companies, along with EPRI and ADA-ES, are
contributing $2.8 million in cash and cost share to the project. The DOE will
contribute $6 million of the $8.8 million in funding for the project. Overall
industry cost share on this project is 32% and ADA-ES has provided cost share of
approximately 16% of the total project.

The four new test sites were specifically selected to provide key operating data
that will be complementary to our earlier demonstrations. The data from this
program should generate widespread interest in the power industry, and these
tests should significantly improve our ability to provide effective and reliable
mercury control systems that minimize the costs and impact on power generation.
Over the 3-year period, ADA-ES expects to recognize $7.4 million in revenue from
the project. Two sites are expected to be tested during 2004.

The project is expected to help promote the marketing arrangement between ADA-ES
and ALSTOM, discussed below, as the premier integrated solutions provider for
the control of mercury emissions from coal-fired power plants.

Commercial Mercury Emissions Control
In December 2002 we entered into an exclusive relationship with ALSTOM
Environmental Control Systems ("ALSTOM"), the largest supplier of equipment to
power plants in North America, to market systems for mercury removal from power
plants and other facilities. In response to pending State and Federal
legislation for mercury emission control, ALSTOM and ADA-ES intend to provide
overall turnkey solutions for mercury control including guaranteed performance.
Such solutions may include all equipment required including carbon storage and
injection equipment, particulate collection equipment or
redesign/rebuild/conversion of existing equipment, monitoring equipment, and
even guaranteed supply of powdered activated carbon (PAC). The partnership will
focus on providing the required equipment and modifications to achieve up to 90%
removal of mercury meeting all applicable standards. The partnership will

                                       7


combine our leading technology position in PAC-based mercury removal, acquired
through our years of development including the DOE sponsored projects, with
ALSTOM's technology in particulate collection (Electrostatic Precipitators and
Fabric Filters) and ALSTOM's experience in mercury removal in the
waste-to-energy business.

Under the terms of the agreement with ALSTOM:
     o    the parties will jointly develop marketing plans and sales objectives;
     o    the parties will grant one another exclusive marketing licenses to
          exploit their respective intellectual property for mercury emission
          control;
     o    the parties will grant one another limited, royalty-free licenses to
          use their respective intellectual property for mercury emission
          control;
     o    the parties will make joint commercial offerings for mercury emission
          control;
     o    ADA-ES and ALSTOM will each pay for their respective costs of
          marketing and development of their mercury control technologies; and
     o    the agreement may be terminated by mutual agreement of ADA-ES and
          ALSTOM, for an uncured breach of a material provision, and/or after
          one year upon three months written notice to the other party.

In 2001 Earth Sciences and NORIT Americas Inc. ("NORIT") entered into a Market
Development Agreement to jointly pursue the market for equipment and sorbents to
remove mercury from coal-fired boilers. Earth Sciences has assigned all of its
rights under that agreement to us as part of the distribution agreement with the
consent of NORIT. The agreement joins us with NORIT, the country's leading
supplier of powdered activated carbon. The goal of the agreement is to jointly
develop mercury control sorbents designed to maximize removal efficiency and
minimize costs. NORIT provides PAC and dosing systems for removing mercury from
flue gas generated from the combustion of municipal and medical solid waste and
hazardous waste. The agreement provides a long-term means for both us and NORIT
to benefit from potential sales of equipment and to participate in the
development of sorbents for this emerging mercury control market.

Under the terms of the agreement with NORIT:
     o    the target market is defined as North American coal-fired utilities;
     o    ADA-ES is responsible for
          o    sorbent identification, technical and economic ranking and
               demonstration testing
          o    market development and sales coverage
          o    equipment contract negotiation, project execution and
               installation supervision
     o    NORIT is responsible for manufacture and/or supply of sorbents and the
          equipment dosing systems;
     o    subject to performance requirements, ADA-ES will represent NORIT
          exclusively in the defined market;
     o    in order for ADA-ES to maintain its exclusive representation of NORIT,
          at least 50% of the market users during the 2004 to 2007 period must
          be supplied by NORIT, in periods beyond those dates, annual minimum
          sales targets will be mutually agreed upon;
     o    for NORIT to maintain exclusivity, it must supply sorbents at prices
          and in quantities to meet the market demand and the ADA-ES sales
          targets;
     o    ADA-ES will earn a commission of 10% on sorbent sales and 5% on
          equipment sales, which commissions continue even if ADA-ES fails to
          maintain its exclusivity through failure to meet its performance
          requirements; and
     o    the parties agree to renew or renegotiate the agreement in good faith
          during the period when regulations requiring mercury emission controls
          are being reviewed which the parties estimate will be in mid-2005.

Other Consulting Services
ADA-ES also offers consulting services to assist utilities in planning and
implementing strategies to meet new government emission standards requiring
reductions in both sulfur dioxide and nitrogen dioxide. ADA-ES is also
developing and testing new chemical blends expected to aid coal-burning
utilities in the variety of problems that may be encountered in switching to
lower cost coals.

Competition
Our primary competition is the conventional FGC technology using either sulfur
trioxide or a combination of sulfur trioxide and ammonia. This technology has
been available commercially since the 1970's and is offered by Chemithon

                                       8


Engineers Ltd., Wahlco, Inc. and Benetech in a variety of forms. Conditioning of
fly ash by injecting small amounts of sulfur trioxide into the flue gas is a
well-proven technique for improving performance of the ESP. Such sulfur trioxide
conditioning loses its effectiveness in application with temperatures over 350
degrees F. The capital costs of conventional FGC technology are in excess of $1
million. Injection of water mist into the flue gas stream is also a known
technique for improving performance of the ESP in certain applications and is
offered by EnviroCare, Inc. The capital cost of a water injection system are
typically $200-300,000. A typical ADA-ES system can cost between
$300,000-600,000. The Company has also introduced a product shown to be
effective in the 300-750 degree range that is suitable for intermittent
application and can augment a sulfur trioxide system and help to avoid use of
ammonia. The competitive advantages of our FGC technology include an effective
temperature range of 300 degrees F to 900 degrees F; a simple injection system;
a non-toxic conditioner that will not become a secondary pollutant; and
chemicals that are safer and easier to handle on site. The variety of products
in the industry to aid ESP performance primarily compete on the basis of
performance and price. The Company usually arranges for a full-scale
demonstration of its products to its potential customers prior to selling its
systems and chemicals for use on a continual basis.

There are no major barriers to entry of our products in the market, however,
utility companies are generally slow to embrace new technologies when they
perceive any potential for disruption in the production of electricity. The
market for ADA-249 is just starting to emerge and no significant competition yet
exists. The market for mercury emission control of coal-fired utilities is
considered an emerging industry driven by regulations that are expected to be
promulgated by the U.S. EPA, state legislatures and/ or the U.S. Congress. See
the discussion above under the caption "Market for Our Products and Services."

Patents
We have received five patents related to different aspects of our technology.
The Company's patents have terms of 20 years measured from the application date,
the earliest of which was in 1995. The patent related to ADA-249 has been
approved for issuance and the related fee has been paid. We expect issuance of
that patent in the near future. The application for the ADA-249 patent was filed
in 2000. We continue to improve our products, and patents applications for
additional products have been submitted. Although important to protect our
continuing business, we do not consider any of such patents to be critical to
the ongoing conduct of our business.

Supply of Chemical for Our Customers
We typically negotiate blending contracts that include secrecy agreements with
chemical suppliers located near major customers. These arrangements minimize
transportation costs while assuring continuous supply of ADA-ES proprietary
chemical blends. Such arrangements have been in place since the spring of 1999
and are generally renewed on an annual basis.

Raw Materials
We purchase equipment from a variety of vendors for the engineered units we
manufacture. Such equipment is available from numerous sources. We purchase our
proprietary chemicals through negotiated blending contracts with chemical
suppliers generally located near each major customer. The chemicals used are
readily available, and several such chemical suppliers can perform to our
requirements.

Seasonality of Activities
The sale of FGC chemicals is dependent on the operations of the utilities to
which such chemicals are provided. Our FGC customers routinely schedule
maintenance outages in the spring of each year. During the period of such
outages, which may range from two weeks to over a month, no FGC chemicals are
used and purchases from us are correspondingly reduced.

Dependence on Major Customers
In 2003 we supplied chemical, equipment and services to 5 FGC customers. We
recognized 12% of our revenue from MidAmerican Energy Co. in Iowa, 8% from
Alliant Power in Wisconsin, and 11% from Cleco Utility Group, Inc. in Louisiana.
ADA-ES' own sales staff markets our technology through trade shows, mailings and
direct contact with potential customers. During 2003 we recognized 45% of our
revenue from services provided under contracts to the U.S. government as
discussed above under Government and Industry Supported Contracts. (See also
Notes 4 and 8 to the Consolidated Financial Statement included elsewhere in this
report).

                                       9


Research and Development Activities
The Company is involved in several R&D contracts funded by DOE and industry
groups primarily directed toward the control of mercury emissions. The Company
cost shares in many of those contracts. For 2003 we estimate that our direct
cost share of R&D in our contracts amounted to approximately $250,000. In
addition, we spent approximately $170,000 and $93,000 directly on research and
development activities related to further development of our technology during
2003 and 2002, respectively.

Employees
As of December 31, 2003 we employed a total of 21 full-time personnel. Included
in this number are 18 people employed at our offices in Littleton, Colorado and
3 in Alabama. In addition, other personnel were employed on a contract basis for
specific project tasks.

Item 2. Description of Property.

Office Lease
ADA-ES leases approx. 12,000 square feet of combined office and warehouse space
in Littleton, Colorado a suburb of Denver. The term of the lease runs through
2009 and the lease agreement has an option to extend the term. We believe the
facilities are sufficient for our needs in to the foreseeable future. We do not
own any real property, but lease all of our office facilities. Annual lease
costs on this space amount to approximately $100,000.

INTRODUCTION
The Company provides environmental technologies and specialty chemicals to the
coal-burning electric utility industry. Revenues are generated through (1) time
and materials contracts for the emerging mercury emission control (MEC) market,
several of which are co-funded by government and industry, (2) the sale of
specialty chemicals and services for flue gas conditioning (FGC), and (3) the
sale of combustion aid (CA) chemicals and services, primarily ADA-249 through a
joint venture with Arch Coal.

Mercury has been identified as a toxic substance and the EPA is under court
order to issue regulations for its control. The growth of the MEC market for the
electric utility industry will most likely be dependent on federal and/or state
regulations, which are in various stages of enactment. As many as 1,100 existing
coal-fired boilers may be affected by such regulations, if and when they are
enacted. Permitting of new coal-fired plants generally requires them to meet
more stringent requirements that likely include MEC. For the near-term, our
revenues from this market will be dependent on (i) DOE- and industry-funded
contracts discussed above, (ii) mercury testing services and (iii) equipment
sales and commissions on sorbents sold to new plants and existing plants
affected by enacted regulations. Although we expect this market to show steady
growth over the next several years, significant revenue growth is anticipated
when federal regulations impact the existing boilers.

The market for our FGC chemicals and services is relatively flat and is expected
to only show modest growth, if any, in the near -term. Margins on these products
are typically higher than what we recognize for our present MEC sales and
represent an important contribution to the overall profitability of the Company.
In spite of several successful demonstrations, market acceptance for our CA
products has not grown as previously expected. Commencement of continuing sales
to a significant customer in 2004 is important, and is expected, if such occurs,
to help promote additional sales.

Liquidity and Capital Resources
The Company had a positive working capital of $1.3 million at 12/31/03. The
amount represents an increase of $745,000 during the year. Management believes
that existing and expected improving working capital, through continued and
improved cash flow from ongoing operations, will be sufficient to meet the
anticipated needs of the Company in 2004. However, there can be no assurances
that the positive cash flow that has been achieved will continue. The Company
also has a $250,000 line-of-credit arrangement with a bank to help with its
working capital needs. No amounts were outstanding under the line as of
12/31/03.

As required under the Distribution Agreement with ESI, in September 2003 the
Company assumed notes payable to Tectonic Construction Co. totaling $1,150,000.
Of that amount $300,000 was paid off with proceed of a convertible debenture
sold to Arch in a like amount as noted below. Also in September, Tectonic
converted $210,000 of the remaining debt into 100,000 shares of the Company's
stock pursuant to the terms of the debt assumed from ESI. The remaining $640,000
was paid off in September with the proceeds from a term loan of the same amount
described below. The Company also assumed other indebtedness from ESI in the
amount of $130,000 related to prior service obligations for certain ESI
employees now employees of the Company, which is expected to be paid off on a
monthly basis over the next three years.

The Company executed a Securities Subscription and Investment Agreement with
Arch in July 2003. Pursuant to the investment agreement, in September 2003 Arch
purchased a $300,000 convertible debenture from the Company (the "Debenture"),
with a term of five years that bears a variable interest rate, currently 6%,
based upon the Wall Street Journal prime rate plus 1.75%. Interest accrues

                                       11


quarterly and is payable with principal at the end of term. Arch also purchased
137,741 shares of the Company's Common stock, for an aggregate purchase price of
$1 million or $7.26 per share. Of the shares issued, 37,741 have been placed in
escrow and a portion those shares may be returned to the Company at the end of
one year depending on the future market price for the Company's shares. As a
part of the purchase Arch was also granted an option to purchase 50,000 shares
for $10.00 per share.

In September the Company borrowed $640,000 from the Colorado Business Bank
("CBB") in the form of a term loan with interest and principal payable in equal
monthly installments of approximately $13,500 over a 4 and one-half year period.
The interest on the term loan is a fixed 7.17% per annum. The proceeds from the
loan were used to pay off the remaining balance of the Tectonic debt assumed
from ESI as part of the spin-off.

The Company's principal source of liquidity is its existing working capital and
operating cash flows as supplemented by its line-of-credit noted above. The
continuation of positive cash flow is somewhat dependent upon the continuation
of chemical sales and operations of the flue gas conditioning (FGC) units
currently in-place in Wisconsin, Louisiana and Iowa, each of which provide an
average monthly cash flow of approximately $20,000. Unsatisfactory results,
which could be caused by a combination or single factor such as changes in coal,
mechanical difficulties (whether in the FGC unit or otherwise), and/or overall
cost/benefit analysis, at any of those units may decrease or end the sale of
chemicals for such units. The Company is also performing services under three
DOE and industry co-funded contracts, which overall are expected to produce an
estimated $5.1 million in revenues in 2004. Of that amount approximately 15%
represents cost share amounts from industry partners, and 50% represents
reimbursement from DOE for costs that pass through the Company. Currently
funding has been approved by the DOE for approximately $4.1 million of its share
of those contracts. If further funding were not approved, the Company would
decrease or cease activities on those contracts and would expect to maintain a
positive cash flow but at a reduced level.

Debt service obligations in 2004 total approximately $145,000. Planned capital
expenditures for ADA-ES to sustain and improve ongoing operations for 2004 are
estimated at $347,000. The Company expects to fund these requirements out of
existing working capital and cash flow from operations.

The Company assumed a defined contribution and 401(k) plan covering all eligible
employees from ESI as of January 1, 2003. The Company matches up to 5% of salary
amounts deferred by employees in the Plan. During 2003, the Company recognized
$71,000 of matching expense; this expense is expected to amount to approximately
$86,000 in 2004. In the past the Company has also made discretionary
contributions to the Plan amounting to approximately 10% of salaries, which
amounts were paid in stock. At December 31, 2003, the Company had authorized a
discretionary contribution of $146,000. In 2004 such discretionary amounts may
be paid as bonuses and based on budget figures may total approximately $206,000.

The Company has recorded net deferred tax assets of $93,000. Based on existing
R&D contracts supported by the DOE and industry, the Company has determined that
it is more probable than not that those deferred tax assets will be realized in
the future.

Cash flow provided from operations totaled $183,000 for 2003 compared to
$279,000 for 2002. Cash flow from operations in 2002 was higher than 2003 as the
result of significant decreases in accounts payable and other liabilities, both
of which changes improved the Company's working capital as of the end of the
year. Cash flow provided from operations in 2003 resulted primarily from the
operating income less non-cash charges for depreciation and amortization plus
and minus other components of working capital. Cash flow from net investing
activities for 2003 includes a use for capital expenditures of $348,000. Cash
flow from financing activities in 2003 consisted of advances to ESI of
$(355,000) and payments on notes payable and debt assumed in the spin-off of
$(968,000), proceeds from the Arch debenture and a new term loan of $940,000 and
proceeds from the sale of stock to Arch of $1million. Cash flow provided from
operations in 2002 also resulted primarily from the operating income plus
non-cash charges for depreciation and amortization and changes in other assets
and liabilities. Cash flow from investing activities for 2002 includes a use for
capital expenditures of $69,000. Cash flow from financing activities in 2002
consisted of advances to ESI of $372,000 and payments on long-term liabilities
of $6,000.

Results of Operations
Revenues totaled $5,863,000 in 2003 versus $5,700,000 in 2002. Revenues for 2003
increased $960,000 due to increased sales in MEC activities and $129,000 from CA
activities, whereas FGC revenues declined by $926,000. The decline in FGC
revenues is a result of a large non-recurring equipment sale in 2002 and
chemical sales in 2002 for a temporary user in 2002 that were not repeated in
2003. The Company sold FGC chemicals and services to five utilities during 2003,
all of which were continuing customers as of year-end. We expect FGC revenues in
2004 to show only modest growth, if any. The Company's government contracts are
subject to audit by the federal government, which could result in adjustment(s)
to previously recognized revenue. The Company believes, however, it has complied
with all the requirements of the contracts and future adjustments, if any, will
not be material. Based on contracts in hand and those expected to be executed in
the near future, total revenues for 2004 are anticipated to grow by
approximately 30% from the 2003 level.

Operating expenses increased by $53,000 in 2003 as a result of increased
activities associated with revenue generating activities. ADA-ES experienced
positive gross margins in 2003 and 2002 of 47% and 46%, respectively. As noted
above, management expects the amount of time and materials work to represent an

                                       12


increasing source of revenues wherein the anticipated gross margins are less
than for our specialty chemical sales. Gross margins for 2004 are expected to
decline from the levels achieved in 2002 and 2003.

Consolidated research and development increased in 2003 by $77,000 to $170,000
as compared to $93,000 in 2002. Future consolidated research and development
expenses, except for those anticipated to be funded by the DOE contracts and
others that may be awarded, are expected to grow at about 10% per year for the
next several years.

General and administrative expenses increased by $189,000 to $2,130,000 in 2003.
The increases result primarily from increases in staff and our office space as
the Company prepares for the anticipated growth in the mercury control market,
other general increases in costs, such as insurance, and costs to comply with
new internal control and reporting standards.

The Company's interest expense totaled approximately $27,000 for 2003 and
$26,000 for 2002. As a result of the transaction related to the spin-off and the
new term loan discussed above we expect interest expense in 2004 to total around
$40,000.

Critical Accounting Policies and Estimates
Significant estimates are used in preparation of the financial statements and
include the Company's allowance for doubtful accounts, which is based on
historical experience. However, a significant amount of the Company's accounts
receivable ($241,000 and $397,000 at December 31, 2003 and 2002, respectively)
is from the federal government. Amounts invoiced for government contracts are
subject to change based on the results of future audits by the federal
government. The Company has not experienced significant adjustments in the past,
and as a we do not expect that a significant adjustment will be made in the
future. The Company uses its judgment to support the current fair value of
goodwill and other intangible assets of $2.1 million on the consolidated balance
sheet. Although the Company has had an independent valuation prepared, which
support its recorded value and, management believes the fair value of other
recorded intangibles are not impaired, market demand for the Company's product
and services could change in the future requiring a write-down in recorded
values. As with all estimates, the amounts described above are subject to change
as additional information becomes available.

New Accounting Policies

In May 2003, the Financial Accounting Standards Board ("FASB") issued Statements
of Financial Accounting Standards No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity." SFAS No. 150
requires issuers to classify as liabilities (or assets in some circumstances)
three classes of freestanding financial instruments that embody obligations for
the issuer. SFAS No. 150 is effective for financial instruments entered into or
modified after May 31, 2003 and is otherwise effective at the beginning of the
first interim period beginning after June 15, 2003. The adoption of SFAS No. 150
has had no immediate impact on the Company's financial position or results of
operations.

        Financial Disclosure.

None.

Item 8A. Controls and Procedures.

Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures designed to ensure that
it is able to collect the information it is required to disclose in the reports
it files with the Securities and Exchange Commission (SEC), and to process,
summarize and disclose this information within the time periods specified in the
rules of the SEC. Based on their evaluation of the Company's disclosure controls

                                       13


and procedures which took place as of a date within 90 days of the filing date
of this report, the Chief Executive and Financial Officer believes that these
controls and procedures are effective to ensure that the Company is able to
collect, process and disclose the information it is required to disclose in the
reports it files with the SEC within the required time periods.

The Company also maintains a system of internal controls designed to provide
reasonable assurance that: transactions are executed in accordance with
management's general or specific authorization; transactions are recorded as
necessary (1) to permit preparation of financial statements in conformity with
generally accepted accounting principles, and (2) to maintain accountability for
assets; access to assets is permitted only in accordance with management's
general or specific authorization; and the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

Since the date of the most recent evaluation of the Company's internal controls
by the Chief Executive and Financial Officer, there have been no significant
changes in such controls or in other factors that could have significantly
affected those controls, including any corrective actions with regard to
significant deficiencies and material weaknesses.

     1.   Automatic extensions for one-year periods.
     2.   Three month written notice of intent to terminate by either the
          Company of the employee.
     3.   Description of position, duties, authority, compensation, benefits and
          obligation of the employee to devote fulltime to the fulfillment of

     8.   Conflicting obligations and obligations upon termination of

contract on January 19, 2004 in order to implement a Board recommended policy to
end commissions on sales, to be replaced by a bonus/incentive program currently
being developed by the Board.
     1.   Six months notice of termination rather than three.
     2.   Mr. Wurster is obligated to devote a minimum of 32 hours per week in
          the fulfillment of his obligations under the agreement.
     3.   In addition to salary, Mr. Wurster receives a commission on certain
          sales representing 5% of revenues from new sales and 2% of revenues
          from continuing sales. Sales from government and co-funded industry
          contracts are excluded from commissions. All commissions stop 30 days
          after termination of employment.

The compensation amounts included in the employment agreements are subject to
annual adjustment and the current compensation levels are shown in the tables
above. None of the Company's employment contracts nor other agreements contain
any provisions for the payment of any amounts that result from or will result
from the resignation, retirement or any other termination of any executive

                                       17


officer's employment with the Company or from a change-in-control of the Company
or a change in the named executive officer's responsibilities following a
change-in-control.


Item 11. Security Ownership of Certain Beneficial Owners and Management and
         Related Stockholder Matters.

The following table provides information with respect to the beneficial

DIRECTOR COMPENSATION
As noted above, under the existing compensation plan, each non-employee director
will receive $5,000 per year, which amount may be payable in common stock of the
Company. This payment plan has not been approved by the shareholders.

                                       19



STOCK OPTION PLAN
During 2003 the Company adopted the 2002 ADA-ES, Inc. Stock Option Plan. One
purpose of the plan was to duplicate the options previously awarded by Earth
Sciences that have been cancelled. Otherwise, the plan is intended to serve to
encourage our key employees, through their individual efforts, to improve our
overall performance and to promote profitability by providing them an
opportunity to participate in the increased value they help create. Options
granted under the plan may be in the form of "incentive stock options" as
defined under section 422 of the Internal Revenue Code of 1986, as amended, or
options that are not incentive stock options. The plan is administered by the
compensation committee of the board of directors. The plan was approved by ESI
as the sole shareholder of ADAES prior to the spin-off distribution of ADA-ES
shares. We reserved 400,000 shares of our common stock for issuance under the
plan. In general, all options granted under the plan will lapse ten years from
the date of grant (five years in the case of a 10% stockholder of our company,
our parent or one of our subsidiaries). In general, the exercise price of an
option will be determined by the compensation committee of the board of
directors at the time the option is granted and will not be less than 100% of
the fair market value of a share of our common stock on the date the option is
granted. The compensation committee may provide in the option agreement that an
option may be exercised in whole immediately or is exercisable in increments
through a vesting schedule. During 2003, 187,310 options were granted under the
plan of which 133,710 represented the duplication of options previously granted
by ESI which were cancelled.

Item 12. Certain Relationships and Related Transactions.

In 2000, Earth Sciences re-negotiated a convertible debenture in the amount of
$1,000,000 (the "Debenture") with Tectonic Construction Co. ("TCC") and a note
in the amount of $250,000 (the "Note") from TCC to extend the due dates and
clarify certain collateral. Mr. Lowdermilk, a director of Registrant, is the
president and majority shareholder of TCC. The Debenture and the Note bore
interest at the greater of prime plus two points or 10% which interest was
payable quarterly. As required under the Distribution Agreement with Earth
Sciences, in September 2003 the Company assumed remaining balance of the notes
payable to Tectonic Construction Co. totaling $1,150,000. Of that amount
$300,000 was paid off with proceeds of a convertible debenture sold to Arch in a
like amount as noted below. Also in September 2003, Tectonic converted $210,000
of the remaining debt into 100,000 shares of the Company's stock pursuant to the
terms of the debt assumed from Earth Sciences. The remaining $640,000 was also
paid-off in September 2003 with the proceeds from a term loan of the same amount
obtained from a commercial bank. The Company also assumed other indebtedness
from ESI in the amount of $130,000 related to past service obligations ($77,000
payable for the benefit of Mr. McKinnies and $44,200 payable for the benefit of
Dr. Bisque, both Directors of the Company).

As discussed above, the Company executed a Securities Subscription and
Investment Agreement with Arch Coal, Inc. in July 2003. Pursuant to the
investment agreement, in September 2003 Arch purchased a $300,000 convertible
debenture from the Company, purchased 137,741 shares of the Company's Common
stock and was also granted an option to purchase 50,000 shares. The Company also
co-markets its ADA-249 product under an agreement with Arch as described above.
Under that arrangement, the Company has recorded revenue of $60,000 and $150,000
in 2002 and 2003, respectively. The Company also granted Arch certain
"piggyback" rights in the event the Company registers certain other equity
securities and certain demand registration rights as part of the transaction. A
designee of Arch, John W. Eaves, has been appointed a seat on the Company's
Board of Directors and management of the Company has agreed in the future to
nominate and to vote all proxies and other shares of stock in the Company which
they are entitled to vote in favor of that designee so long as Arch holds no
less 100,000 shares of the Company's common stock.

To the Board of Directors and Stockholders
ADA-ES, Inc. and Subsidiary
Littleton, Colorado


We have audited the accompanying consolidated balance sheet of ADA-ES, Inc. and
Subsidiary as of December 31, 2003, and the related consolidated statements of
operations, and accumulated deficit and cash flows for the years ended December
31, 2003 and 2002. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of ADA-ES,
Inc. and Subsidiary as of December 31, 2003, and the results of their operations
and their cash flows for the years ended December 31, 2003 and 2002, in
conformity with accounting principles generally accepted in the United States of
America.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


 1. SUMMARY OF NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:
    -------------------------------------------------------------------

     Nature of Operations - The accompanying consolidated financial statements
     include the accounts of ADA-ES, Inc. (ADA-ES) and its wholly-owned
     subsidiary, ADA Environment Solutions, LLC (ADA). ADA-ES was a wholly-owned
     subsidiary of Earth Sciences, Inc. ("ESI" or the "Parent") until September
     2003 when ESI distributed all of the then outstanding stock of ADA-ES to
     its stockholders. ADA-ES' only asset is its investment in its wholly-owned
     subsidiary, ADA. All significant intercompany transactions have been
     eliminated. Collectively, ADA and ADA-ES are referred to as the Company.

     The Company is principally engaged in providing environmental technologies
     and specialty chemicals to the coal-burning utility industry. The Company
     also generates substantial revenue from contracts co-funded by the
     government and industry. The Company sales occur principally throughout the
     United States.

     Cash Equivalents - For purposes of the statement of cash flows, the Company
     considers all highly liquid debt instruments with original maturities of
     three months or less to be cash equivalents.

     Receivables and Credit Policies - Trade receivable are uncollateralized
     customer obligations due under normal trade terms requiring payment within
     30 days from the invoice date. Management reviews trade receivables
     periodically and reduces the carrying amount by a valuation allowance that
     reflects management's best estimate of the amount that may not be
     collectible.

     Inventories - Inventories are stated at the lower of cost or market,
     determined by the first-in, first-out method and consist of supplies.

     Percentage of Completion - ADA follows the percentage of completion method
     of accounting for all significant long-term contracts excluding government
     contracts. The Company recognizes revenue on government contracts based on
     the time and expenses incurred to date. The percentage of completion method
     of reporting income from contracts takes into account the cost and revenue
     to date on contracts not yet completed. Except for the government contracts
     (discussed in Note 4), the Company had no material long-term contracts in
     progress at December 31, 2003.

     Revenue Recognition - ADA chemical sales are recognized when products are
     shipped to customers. A reserve is established for any returns, based on
     historical trends. Chemical products are shipped FOB shipping point and
     title passes to the customer when the chemicals are shipped. The Company's
     sales agreements do no contain right of inspection or acceptance provision
     and products are generally received by customers within one day of
     shipment. The Company has had no significant history of non-acceptance, nor
     of replacing goods damaged or lost in transit. ADA equipment sales are
     recognized when the equipment is delivered and installed and all return or
     buy back privileges have expired. Consulting revenue is recognized as
     services are performed and collection is assured.

                                      F-7

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     Property and Equipment - Property and equipment is stated at cost.
     Depreciation on assets is provided using the straight-line method based on
     estimated useful lives ranging from 3 to 10 years. Maintenance and repairs
     are charged to operations as incurred. When assets are retired, or
     otherwise disposed of, the property accounts are relieved of costs and
     accumulated depreciation and any resulting gain or loss is credited or
     charged to income.

     Intangible Assets - Intangible assets principally consist of patents.
     Acquired patents are being amortized over a 7-year period using the
     straight-line method, which is less than the remaining legal life of the
     patents. Patents obtained by the Company directly are being amortized over
     a 17-year life.

     Intangible assets consist of:

                                                 Accumulated
                                     Cost        Amortization        Net
                                 ------------    ------------   ------------

           Patents               $    135,000    $   (23,000)   $    112,000
                                 ============    ============   ============


     Goodwill - Goodwill consists of the excess of the aggregate purchase price
     over the fair value of net assets of businesses acquired. Goodwill was
     amortized over a 10-year period through December 31, 2001. As of January 1,
     2002, the Company adopted FAS 142, Goodwill and Other Intangible Assets.
     Under FAS 142, Goodwill is no longer amortized, but subject to an
     impairment evaluation, which is performed in the fourth quarter of each
     year. During fiscal 2002, the Company engaged an investment banking firm to
     perform a valuation of the Company. As a result of this evaluation, which
     was reviewed and updated for 2003, the Company concluded that no impairment
     of its goodwill was required.

     Receivable from Parent - As discussed above, ADA was a wholly-owned
     subsidiary of ESI. The net of intercompany transactions between ADA and ESI
     were set forth in the Receivable from Parent and shown in the accompanying
     Consolidated Statement of Stockholder's Equity. The intercompany
     transactions consisted of cash distributions from ADA to the Parent and the
     payment of certain ADA pension expenses (see Note 7) by the Parent using
     its stock.

     Operating Costs - Operating costs include all labor, fringe, subcontract
     labor, chemical costs, materials, equipment, supplies and travel costs
     directly related to ADA's production of revenue.

     General and Administrative - General and administrative costs include
     personnel related fringe benefits, sales and administrative staff labor
     costs, facility costs and other general cost of conducting business.

                           ADA-ES, INC. AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     Net Income Per Share - Net income per share is presented in accordance with
     the provisions of Statement of Financial Accounting Standards (SFAS) No.
     128, Earnings Per Share. Basic EPS is calculated by dividing the income or
     loss available to common shareholders by the weighted average number of
     common shares outstanding for the period. Diluted EPS reflects the
     potential dilution that could occur if securities or other contracts to
     issue common stock were exercised or converted into common stock. As the
     Company did not have any options outstanding as of December 31, 2002
     diluted EPS is not presented for that period. For 2003 and 2002, the
     weighted average number of common shares outstanding for the periods shown
     have been adjusted to reflect the spin-off as if it occurred on January 1,
     2002. As of December 31, 2003, the Company has 267,310 options outstanding
     that can be converted into common stock (see Note 6).

     Impairment of Long-Lived Assets - The Company follows Statement of
     Financial Accounting Standards (SFAS) No. 144, Impairment of Long-Lived
     Assets. In the event that facts and circumstances indicate that the cost of
     assets or intangible assets may be impaired, an evaluation of
     recoverability would be performed.

     Income Taxes - The Company accounts for income taxes under the liability
     method of SFAS No. 109, whereby current and deferred tax assets and
     liabilities are determined based on tax rates and laws enacted as of the
     balance sheet date. Income taxes for financial reporting purposes for the
     Company for 2002 and the period through September 11, 2003 are based as if
     the Company filed a separate return, even though the Company files a
     consolidated income tax return with ESI for those periods.

     Research and Development Costs - Research and development costs are charged
     to operations in the period incurred.

     Stock-Based Compensation - The Company records expense for stock options
     granted to employees by using APB 25, which requires expense to be
     recognized only to the extent the exercise price of the stock-based
     compensation is below the market price on the date of grant. Transactions
     in equity instruments with non-employees for goods or services are
     accounted for on the fair value method. Because the Company has elected not
     to adopt the fair value accounting described in SFAS No. 123 for employees,
     it is subject only to the disclosure requirements described in SFAS No.
     123.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Had compensation cost been determined based on an estimate of the fair
     value consistent with the method of SFAS No. 123 at the grant dates for
     awards under those plans, the Company's net income and EPS would have been
     reduced to the pro forma amounts indicated below.

     There were no options granted in 2002 and options granted in 2003 had an
     exercise price equal to the market price on the date of the grant. The
     average fair value of each employee option granted in 2003 was
     approximately $2.32 and was estimated on the date of grant using the
     Black-Scholes option-pricing model with the following weighted average

     Use of Estimates - The preparation of the Company's consolidated financial
     statements in conformity with generally accepted accounting principles
     requires the Company's management to make estimates and assumptions that
     affect the amounts reported in these financial statements and accompanying
     notes. Actual results could differ from those estimates. The Company makes
     significant assumptions concerning the impairment of and the remaining
     realizability of its intangibles. In addition, the Company enters into
     significant research contracts with the U.S. Government, which are subject
     to future audits. Pursuant to the contracts, the Company makes estimates of
     certain overhead and other rates, which may be adjusted as a result of such
     audits. At this time, the Company does not believe any future government
     audit will result in material adjustment to previously recorded revenues.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     Comprehensive Income/Loss - SFAS No. 130 establishes standards for
     reporting and display of comprehensive income/loss, its components and
     accumulated balances. Comprehensive income/loss is defined to include all
     changes in equity except those resulting from investments by owners and
     distributions to owners. Comprehensive income was the same as net income in
     2003 and 2002.

     Segment Information - The Company follows SFAS No. 131, Disclosure About
     Segments of an Enterprise and Related Information. SFAS No. 131 establishes
     standards on the way that public companies report financial information
     about operating segments in annual financial statements and requires
     reporting of selected information about operating segments in interim
     financial statements issued to the public. It also establishes standards
     for disclosures regarding products and services, geographic areas, and
     major customers. SFAS No. 131 defines operating segments as components of a
     company about which discrete financial information is available that is
     evaluated regularly by the chief operating decision maker in deciding how
     to allocate resources and in assessing performance. The Company has three
     reportable segments even though it derives its revenues primarily from
     specialty chemicals and government contracts.

     Recently Issued Accounting Pronouncements - In May 2003, the Financial
     Accounting Standards Board ("FASB") issued Statements of Financial
     Accounting Standards No. 150, Accounting for Certain Financial Instruments
     with Characteristics of Both Liabilities and Equity. SFAS No. 150 requires
     issuers to classify as liabilities (or assets in some circumstances) three
     classes of freestanding financial instruments that embody obligations for
     the issuer. SFAS No. 150 is effective for financial instruments entered
     into or modified after May 31, 2003 and is otherwise effective at the
     beginning of the first interim period beginning after June 15, 2003. The
     adoption of SFAS No. 150 has had no immediate impact on the Company's
     financial position or results of operations.

2. SPIN-OFF OF ADA-ES:
   ------------------

     In March 2003, the Company and ESI entered into an agreement (the
     "Distribution Agreement") for the pro rata distribution of all the common
     stock of the Company to the stockholders of ESI based on a record date of
     August 29, 2003 and thereby formed a separate public company. The
     Distribution Agreement required certain allocations of cash and liabilities
     among ESI and the Company prior to the distribution of the Company's common
     stock.

     Based on the Distribution Agreement, ESI issued one share of ADA-ES for
     each ten shares currently owned by the stockholders of ESI. Approximately
     3,344,000 shares of ADA-ES were issued to the shareholders of ESI in
     September 2003 to effect the spin-off.

     In a related transaction, ADA-ES entered into an investment agreement with
     Arch Coal, Inc. (Arch). The Arch Coal Agreement was subject to the spin-off
     of ADA-ES from ESI. The agreement provided for $300,000 of additional debt
     (the proceeds of which were used to pay down debt assumed in the spin-off)
     and $1,000,000 of equity for the issuance of shares of common stock. The
     price of the stock of $7.26 per share was based on a multiple of the market
     price for the ESI common stock at the time of the spin-off.

4. GOVERNMENT AND INDUSTRY FUNDED CONTRACTS:
   ----------------------------------------

     ADA has performed activities under four contracts awarded by the Department
     of Energy (the "DOE") that contributed a total of $2,164,000 and $2,650,000
     to revenues in 2003 and 2002, respectively. These amounts are included in
     Mercury emission control revenues of $1,956,000 and $2,327,000, and Flue
     gas conditioning revenues of $208,000 and $323,000, in 2003 and 2002,
     respectively. ADA typically invoices the DOE monthly for estimated labor
     and expenditures plus overhead factors, less cost share amounts. The total
     approved DOE budgets amount to $18 million, of which the Company's and
     industry partners' cost-share portion is $6 million. The remaining unearned
     amount of the contracts expected to be recognized by the Company in 2004
     (including cash contributions by other industry partners) is $4.8 million.
     The Company is in the process of working with DOE on a new contract in
     which the Company will be a subcontractor and primary technology provider
     for 2003 through 2008. These contracts are subject to audit and future
     appropriation of funds by Congress. The Company's historical experience has
     not resulted in significant adverse adjustments to the Company, however the
     government audits for years ended 2003 and 2002 have not yet been
     finalized.

5. DEBT:

6. STOCKHOLDERS' EQUITY:
   --------------------

     Shares Issued for Pension Expenses - ESI issued shares of its common stock
     in 2003 and 2002, respectively, for the payments of approximately $20,000
     and $134,000 of ADA pension related expenses (see Note 7), based upon the
     per share value of unrestricted common stock of ESI at the time of
     exchanges. This amount was recorded as an additional payable of the Company
     to ESI. These amounts were recorded in the Receivable from Parent and shown
     in the accompanying financial statements in the Stockholder's Equity
     section.

     Sale of Stock, Convertible Debenture and Grant of Option to Arch - In
     September 2003, the Company sold 137,741 shares to Arch Coal for $1 million
     and sold a convertible debenture for $300,000 both pursuant to an
     investment agreement. Of the shares sold, 37,741 have been placed in escrow
     and a portion or all may be returned to the Company if the market price of
     the Company's shares exceeds a minimum of $9.08 for a twenty-day continuous
     period during the one-year period from the date of their issuance. The
     Debenture is convertible into shares after August 2005 at the lower of $20,
     $30, and $40 per share in the years expiring March 2006, 2007, and 2008,
     respectively, or 150% of the then current market price. The Debenture is
     convertible solely at the discretion of Arch. As a part of the share
     purchase Arch was also granted an option to purchase 50,000 shares for
     $10.00 per share. The option expires in five years. Under the option, Arch
     may purchase 16,667 shares after August 2004, another 16,667 shares after
     August 2005, and the remaining shares after August 2006.

     Conversion of Debt to Shares - The Company assumed convertible debt to a
     related party as part of the spin-off transaction (see Note 10), which
     debt, to the extent allowable, was converted to stock in September 2003.
     Upon such conversion, the Company issued 100,000 shares of its common stock
     in exchange for $210,000 of such debt.

     Stock Options - The Company did not issue any options during 2002. However,
     as a result of the spin-off (Note 2), options outstanding at ESI were
     exchanged for options of ADA-ES based on the effective share exchange of
     one option share for each ten options outstanding at ESI based on the price
     and terms the options were originally issued. If this exchange had occurred
     at December 31, 2002, pro forma options outstanding would have been
     133,710, with a weighted average exercise price of $2.50. The following is
     a table of options issued during 2003:

9. INCOME TAXES:
   ------------

     Prior to September 2003, the Company was a wholly owned subsidiary of ESI.
     The Company's tax attributes were passed through to its Parent and any
     taxable income was offset by the Parent's tax loss carryforwards. In
     connection with the spin-off, the Company retained its tax loss
     carryforward generated in the current year returns. The Company's tax basis
     of its assets and liabilities carry forward after the spin-off. The
     following lists the Company's deferred tax assets and liabilities as of
     December 31, 2003:

          Current assets (liabilities):
              Prepaid expenses                                $  (23,000)
              Deferred revenues and compensation                  69,000
                                                              ----------

                                                              ----------

                                                              $   93,000
                                                              ==========

     As of December 31, 2003, the Company had approximately $40,000 of tax loss
     carryforwards. The Company's valuation allowance as of December 31, 2003
     and 2002 was $0 and $80,000, respectively, and as such, the valuation
     allowance was reduced by $80,000 in 2003. During the years ended December
     31, 2003 and 2002, the Company's deferred tax valuation allowance increased
     by approximately $80,000 in 2003 and reduced by approximately $174,000 in
     2002 (2002 calculated on a "stand-alone" basis). The following is a
     reconciliation of the actual income tax rate - expense (benefit) to the
     expected combined Federal and State tax rate of approximately 37%:

                                                        2003            2002
                                                        ----            ----

           valuation allowance (decrease)              (67%)            (37%)
                                                       ----             ----

         Actual income tax rate                         (29%)              0%

     During 2003, the Company determined that it was more probable than not that
     the Company's net deferred tax asset would be realized in the future and
     accordingly, the Company eliminated the related valuation allowance.

10. RELATED PARTY TRANSACTIONS:
    --------------------------

     In 2003, pursuant to the Distribution Agreement with ESI (see Note 2) the
     Company assumed a convertible debenture in the amount of $1,000,000 (the
     "Debenture") with Tectonic Construction Co. ("TCC") and a note in the
     amount of $150,000 (the "Note"). A director of the Company is the president
     and majority shareholder of TCC. The Debenture and the Note bore interest
     at the greater of prime plus two points or 10% which interest was payable
     quarterly. Of that amount $300,000 was paid off with proceeds of a
     convertible debenture sold to Arch in a like amount. Also, in September of
     2003, TCC converted $210,000 of the remaining debt into 100,000 shares of
     the Company's stock pursuant to the terms of the debt assumed from ESI. The
     remaining $640,000 was also paid off in September with the proceeds from a
     term loan of the same amount obtained from a commercial bank.

     As discussed above in Note 2, the Company executed a Securities
     Subscription and Investment Agreement with Arch Coal, Inc. in July 2003.
     Pursuant to the investment agreement, in September 2003 Arch purchased a
     $300,000 convertible debenture from the Company, purchased 137,741 shares
     of the Company's Common stock and was also granted an option to purchase
     50,000 shares. The Company also co-markets its ADA-249 product under an
     agreement with Arch as described above. Under that arrangement, the Company
     has recorded revenue of $150,000 and $60,000 in 2003 and 2002,
     respectively. The Company also granted Arch certain "piggyback" rights in
     the event the Company registers certain other equity securities and certain
     demand registration rights as part of the transaction. A designee of Arch
     has been appointed a seat on the Company's Board of Directors and
     management of the Company has agreed in the future to nominate and to vote
     all proxies and other shares of stock in the Company which they are
     entitled to vote in favor of that designee so long as Arch holds no less
     than 100,000 shares of the Company's common stock.
