2003 the Company adopted the 2002 ADA-ES, Inc. Stock Option Plan and reserved
400,000 shares of Common Stock for issuance under the plan. In general, all
options granted under the plan expire ten years from the date of grant unless
otherwise specified by the Company&#146;s Board of Directors. 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 the first quarter of 2006, 19,900 options
were granted under this plan.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">During
2004, the Company adopted the 2004 Executive Stock Option Plan. This plan
authorized the grant of up to 200,000 options to purchase shares of the
Company&#146;s Common Stock to executive officers of the Company, all of which
were granted in 2004. The option exercise price of $8.60 per share was the
market price on the date of the grant. The options are exercisable over a
10-year period based on a vesting schedule that may be accelerated based on
performance of the individual recipients as determined by the Board of
Directors. In February 2007, the Board of Directors authorized the vesting of
17,258 options under this plan with a fair value of $35,000. As of March 31,
2007 and 2006, 56,486 and 40,228 options were exercisable, respectively.</FONT></FONT></P>

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">During  2004,
the Company adopted a plan (the &#147;2004 Plan&#148;) for the issuance of  shares and
the grant of options to purchase shares of the Company&#146;s Common  Stock to the Company&#146;s
non-management directors. The 2004 Plan provided for  the award of stock of 603 shares
per individual non-management director or 4,221  shares in total, and the grant of
options to purchase 5,000 shares of common stock per individual non-management  director
or 35,000 in total, all of which were formally granted and issued in  2005 after approval
of the 2004 Plan by the stockholders. The option exercise  price of $13.80 per share for
the stock options granted on November 4, 2004 was  the market price on the date of the
grant. The options are exercisable over a  period of five years and will vest over a
three-year period, one-third each year  for continued service on the Board. If such
service is terminated, the  non-vested portion of the option will be forfeited. During
the first quarter of  2006, 10,000 of such options and during the second quarter of 2006
another 5,000  of such options were forfeited after the resignation of three directors.
As of  March 31, 2007 and 2006, 5,001 and 8,335 options were vested and exercisable,
respectively.</FONT></FONT></P>

the Company adopted the 2005 Directors&#146; Compensation Plan (the  &#147;2005 Plan&#148;),
which authorized the issuance of shares of Common Stock  and the grant of options to
purchase shares of the Company&#146;s Common Stock  to non-management directors. The 2005
Plan provides a portion of the annual  compensation to non-management directors of the
Company in the form of awards of  shares of Common Stock and vesting of options to
purchase Common Stock of the  Company for services performed for the Company. Under the
2005 Plan, the award  of stock is limited to not more than 1,000 shares per individual
per year, and  the grant of options is limited to 5,000 per individual in total. The
aggregate  number of shares of Common Stock reserved for issuance under the 2005 Plan
totals 90,000 shares (50,000 in the form of stock awards and 40,000 in the form  of
options). The exercise price for options granted under the 2005 Plan will be the market
price on the date of grant,  the shares of Common Stock underlying the option will vest
for exercise at a rate of no  more than 1,667 shares per annual period per individual,
and any unvested options that are outstanding at the date the individual is no longer is
a  Director will be forfeited. The 2005 Plan, if not terminated earlier by the  Board,
will terminate ten years after the date of its adoption. In January 2006  the Board of
Directors authorized the issuance of 1,000 shares of Common Stock  each, or a total of
7,000 shares and in August 2006 the Board granted 15,000  options, to the non-management
directors of the Company. As of March 31, 2007  none of the options were vested and
exercisable.</FONT></FONT></P>

Interpretation of FASB Statement No. 109,&#148; which was  effective for our year
beginning January 1, 2007. This interpretation was  issued to clarify the accounting for
uncertainty in income taxes recognized in  the financial statements by prescribing a
recognition threshold and measurement  attribute for the financial statement recognition
and measurement of a tax  position taken or expected to be taken in a tax return. FIN 48
requires the  recognition of penalties and interest on any unrecognized tax benefits. Our
policy is to reflect penalties and interest as part of income tax expense as  they become
applicable. We  adopted the provisions of FIN 48 on January 1, 2007. No  unrecognized tax
benefits were  recorded as of the date of adoption.The  Company files income tax returns

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2"><B>Overview</B><BR>We
provide environmental technologies and specialty chemicals to the coal-burning
electric utility industry. Revenues are generated through (1) time and materials
and fixed-price contracts for the emerging mercury emission control (MEC)
market, several of which are co-funded by government (Department of Energy
&#151; DOE) and industry and (2) the sale of specialty chemicals and services
for flue gas conditioning (FGC) and other applications.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Mercury  has
been identified as a toxic substance and, pursuant to a court order, the EPA  issued
regulations for its control in March 2005. We believe that the long-term growth of the
MEC market for the electric utility industry will most likely depend on how  industry
chooses to respond to federal and state regulations, which are in  various stages of
enactment and challenge in the courts. As many as 1,100  existing coal-fired boilers may
be affected by such regulations, if and when  they are fully implemented. We have
recently seen a significant increase in new  plant projects. DOE&#146;s latest report
issued in 2006 includes 153 potential  new projects totaling 93GW of capacity. 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 mentioned above, (ii) mercury
testing  services and (iii) equipment sales and commissions on sorbents sold to new
plants and existing plants affected by the implementation of enacted  regulations. State
regulations and increasing numbers of consent decrees are  becoming the largest market
driver for this part of our business. Although we  expect this market to show steady
growth over the next several years, we believe  the most significant revenue growth will
occur when final federal regulations  impact a significant portion of previously
uncontrolled, existing boilers.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">The
market for our FGC chemicals and services is relatively flat and is expected to
continue to decline in the near-term. Margins on these products are typically
higher than what we recognize for our present MEC sales and represent an
important but decreasing contribution to our overall profitability.</FONT></FONT></P>

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">In
2006, we signed contracts for ten Activated Carbon Injection (ACI) systems to be
delivered in 2006 and 2007, bringing the total number of ACI systems installed
or in process as of December 31, 2006 to twelve. Thus far in 2007, we have
signed contracts or orders to proceed for seven ACI systems to be delivered in
2007 and 2008, bringing our total number of ACI systems installed or currently
in process to 19. In addition, one system was installed in partnership with a
third party for which we provided design services through a DOE contract. We are
entitled to commissions on future sorbent sales to the utility industry in North
America purchased from a vendor with whom we have a relationship. Remaining
revenue from the ACI system contracts totaled $3.3 million as of January 1,
2007, of which approximately $1.6 million was recognized in the first quarter of
2007. Remaining revenues from ACI contracts totaled approximately $7.7 million
as of March 31, 2007 and is expected to be recognized in 2007 and 2008.</FONT></FONT></P>

Operations &#150; 1<SUP>st</SUP> Quarter 2007 versus 1<SUP>st</SUP> Quarter 2006</B><BR>Revenues
totaled $3,904,000 for 2007 versus $3,649,000 in 2006, representing an increase  of 7%.
Revenues in our MEC segment for 2007 increased by $509,000 (16%), and  FGC and other
activities decreased by ($254,000) (48%). We have been hiring  personnel in response to
the growth we have realized in the past and expect to  achieve in 2007, and have more
than doubled the number of engineers in our commercial equipment group, who are  integral
to our MEC operations.  Adequate resources of skilled labor have been and are  expected
to be available to meet anticipated needs.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Revenues  in
2007 from the MEC segment were comprised of government and industry-supported  contracts
(42%), sales and installation of ACI systems and minor amount of  commissions on
activated carbon (AC) sales (49%) and consulting services (9%),  compared to 44%, 33% and
9%, respectively, in 2006. For the quarter, our DOE and  industry demonstration contract
revenues totaled $1.5 million representing a  decrease of 5% from 2006 revenues. The
remaining unearned amount of the  contracts was $11.7 million as of March 31, 2007, of
which $7.4 million is  expected to be recognized in 2007 (including cash  contributions
by other industry partners). ACI systems and commissions earned on the  sale of
activitated carbon (AC) contributed  approximately $1.8 million to MEC revenues
recognized for the quarter,  increasing 48% from the 2006 contribution to revenue of $1.2
million. We had  contracts in progress at quarter-end for supply of ACI systems with
remaining  revenue of approximately $7.7 million which we expect to complete and realize
in  2007 and 2008. The most significant growth occurred in the sales and  installations
of ACI systems and AC commissions, which increased $573,000 in the  quarter and is the
result of an increasing number of system sales as noted  above. Revenues from AC
commissions represent approximately  $159,000 of that amount. We expect growth in 2007
in the MEC segment to result primarily from an  increasing number of ACI systems and AC
commissions sales in response to mercury  emission control legislation and from existing
government and industry-supported  contracts. Our contracts with the government are
subject to audit by the federal  government, which could result in adjustment(s) to
previously recognized  revenue. We believe, however, that we have complied with all
requirements of the  contracts and future adjustments, if any, will not be material. In
addition, the  federal government must appropriate funds on an annual basis to support
DOE contracts, and funding is always subject to unknown and uncontrollable
contingencies. Revenues from consulting services included in the MEC segment  increased
approximately $13,000, from 2006 to 2007.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">FGC
and other revenues decreased by $254,000 or 48% due to fewer shipments of
chemical to continuing customers. Included in 2006 revenues
was a test program that was not repeated in 2007. We expect FGC and other
revenues in 2007 to be significantly lower than 2006, as we believe that planned
customer purchases for 2007 will be less than such purchases made in 2006.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Cost  of
revenues increased by $44,000 or 2% in 2007 from 2006 primarily as a result  of increased
revenues for the same periods. Gross margins were 41% for the first quarter  as compared
to 38% in 2006. The increase is a result of increased margins in the  MEC segment as
discussed below.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Cost
of revenues for the MEC segment increased by $161,000 in 2007 or 8%, as compared
to 2006 primarily as a result of the increased revenue generating activities
noted above. Gross margins for this segment were 40% for the first quarter as compared to
35% for 2006. The improvement in gross margins from the prior year resulted from
higher margins on DOE contracts as our cost share percentage on those contracts
has decreased, offset by somewhat lower margins on ACI system sales as that
market is developing. The changes in MEC segment profits from 2006 to 2007 are a
result of the same factors.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Cost  of
revenues for the FGC and other segment decreased by $117,000 or 46% in 2007,  as compared
to 2006. We performed a demonstration in the 1<SUP>st</SUP> and  2<SUP>nd</SUP> quarters
of 2006 was not repeated in 2007 that contributed to  higher costs for those periods.
Gross margins for this segment were 51% for 2007  as compared to 52% in 2006. The
decrease in gross margins from 2006 to 2007 is a  result of increased FGC sales of a
product we license from ARKAY Technologies,  which carry a lower margin than historical
FGC sales and the increased costs in  development projects . FGC revenues represent
primarily chemical sales, which  carry a higher margin than the typical fixed price and
time and materials sales  in MEC revenues. FGC and other revenues comprised 7% of total
revenues in 2007,  compared to 14% in 2006. The changes in the FGC segment profits from
2006 to  2007 are a result of the same factors.</FONT></FONT></P>

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">We
expect the amount of fixed price and time and materials work in the MEC segment
for the near term to represent an increasing source of revenue. Overall gross
margins for 2007 are therefore expected to decline somewhat from the levels
achieved in 2006, as a result of an increasing proportion of fixed price and
time and materials work, our assumption of an increasing share of costs in the
field demonstration projects in which we have elected to participate and pricing
pressure caused by increased competition.</FONT></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">General  and
administrative expenses increased by $609,000 or 72% to $1,461,000 in 2007.  The dollar
increase in 2007 resulted primarily from increased audit and Sarbanes-Oxley (SOx)
compliance costs  ($240,000); increased legal, consulting and outside labor costs
($138,000), increased  administrative wage costs ($115,000); and increased  insurance
costs ($34,000). We expect  our audit and SOx costs to decrease  substantially in future
periods.</FONT></FONT></P>

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Research
and development expenses increased by $52,000 or 17% in 2007 as compared to
2006. We incur R&amp;D expenses not only on direct activities we conduct but
also by sharing a portion of the costs in the government and industry programs
in which we participate. 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 continue to grow at a rate of about 10% annually
for the next several years. Of the amount incurred in 2007, $125,000 was
directly related to DOE contracts.</FONT></FONT></P>

<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">MEC
segment profits increased by $268,000 or 37% to $996,000 as compared to 2006.
The increase was primarily a result of increased MEC segment revenues and
improved margins on our DOE contracts as described above. FGC and other segment
profits decreased by $162,000 or 98% to $3,000 as compared to 2006. The decrease
was primarily the result of increasing project development costs incurred during
the period, lower margin chemical sales and decreasing segment revenues.</FONT></FONT></P>

deferred income tax benefit for 2007 represents our expected effective tax rate
of approximately 31% for 2007, which is less than the rate of 34% we recognized
for the first quarter of 2006. The decrease is primarily the result of larger
impact of R&amp;D tax credits for 2007 as compared to the amount estimated for
the first quarter of 2006.</FONT></FONT></P>

and Capital Resources</B><BR>We had
a positive working capital of $17.3 million at March 31, 2007, compared to
working capital of $18.5 million at December 31, 2006. The decrease is a result
primarily from our continued investments in our development projects and capital
expenditures, and fluctuations in operating assets and liabilities in the normal
course of business. In addition to working capital, we had long-term investments
in securities, accounted for as &#147;available-for-sale&#148; investments, of
approximately $5.6 million and $5.3 million at March 31, 2007 and December 31,
2006, respectively. We intend to retain a portion of these investments to
demonstrate strength in our financial position to support performance guarantees
we have been and may continue to provide on sales of ACI systems. We may also
use a portion of such investments and cash on hand to fund growth of the
Company, which may include expansion of product offerings and strategic
acquisitions. We believe that existing and expected future working capital, will
be sufficient to meet our anticipated operating needs in 2007.</FONT></FONT></P>

principal source of liquidity is our existing working capital and operating cash
flow. Future 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 Illinois, Louisiana and Iowa. These units provided
an average monthly cash flow of approximately $13,000 each thus far in 2007.
While we have been awarded a contract to perform a demonstration project at
another plant beginning in the first half of 2007, we are not certain that this
demonstration will be successful or will result in future sales of FGC equipment
and chemicals. Unsatisfactory results for any of our FGC customers, which could
be caused by a single factor (or some combination of factors) 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, are likely to result in a
decrease or termination of the sale of chemicals for such units and a reduction
in the cash flow we have historically received, thereby reducing that portion of
our liquidity that has been provided by positive cash flow.</FONT></FONT></P>

existing working capital and cash flow from operations. This  amount does not include
amounts we may choose to spend on specific development  projects to secure our position
in the activated carbon market. The  Board has committed approximately $4 million from
internal funds, which we expect to  expend through August 2007. We believe this will

significant long-term contracts, which is based on estimates of gross margins
and of the costs to complete such contracts. In addition, amounts invoiced for
government contracts are subject to change based on the results of future audits
by the federal government. We have not experienced significant adjustments in
the past, and we do not expect significant adjustments will be required in the
future. We also use our judgment to support the current fair value of goodwill
and other intangible assets of $2.3 million on the consolidated balance sheets.
Management believes the fair value of other recorded intangibles is not
impaired, although market demand for our products and services could change in
the future, which would require a write-down in recorded values. As with all
estimates, the amounts described above are subject to change as additional
information becomes available, although we are not aware of anything that would
cause us to believe that any material changes will be required in the near term.</FONT></FONT></P>

Issued Accounting Policies</B><BR>In  June 2006, the FASB issued FIN 48, &#147;Accounting for
Uncertainty in Income  Taxes &#151; An Interpretation of FASB Statement No. 109,&#148; which
was  effective for our year beginning January 1, 2007. This interpretation was  issued to
clarify the accounting for uncertainty in income taxes recognized in  the financial
statements by prescribing a recognition threshold and measurement  attribute for the
financial statement recognition and measurement of a tax  position taken or expected to
be taken in a tax return. FIN 48 requires the  recognition of penalties and interest on
any unrecognized tax benefits. Our  policy is to reflect penalties and interest as part
of income tax expense as  they become applicable. We  adopted the provisions of FIN 48 on
January 1, 2007. No  unrecognized tax benefits  were recorded as of the date of
adoption.&nbsp;We file income tax returns in  the U.S. federal and various
state  jurisdictions. &nbsp;We are no longer subject to U.S.  federal and state and local
examinations by tax authorities for years before 2004. </FONT></FONT></P>

disclosures about fair value measurements. SFAS 157  focuses on creating consistency and
comparability in fair value measurements.  SFAS 157 is effective for fiscal years

<!-- MARKER FORMAT-SHEET="Para Flush" -->
<P ALIGN="LEFT"><FONT FACE="Times New Roman, Times, Serif"><FONT SIZE="2">Our
CEO and CFO do not expect that our internal controls and procedures will prevent
all error and all fraud. Although our internal controls were designed to provide
reasonable assurance of achieving their objectives, a control system, no matter
how well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the system are met. Further, the design of a
control system must reflect the fact that there are resource constraints, and
the benefits of controls must be considered relative to their costs. Because of
the inherent limitations in all control systems, no evaluation of controls can
provide absolute assurance that all control issues and instances of fraud, if
any, have been detected. These inherent limitations include the realities that
judgments in decision-making can be faulty and that breakdowns can occur because
of simple error or mistake. Additionally, controls can be circumvented by the
individual acts of some persons, by collusion of two or more people or by
management override of the control. The design of any system of controls is also
based partly on certain assumptions about the likelihood of future events, and
there can be no assurance that any design will succeed in achieving its stated
goals under all potential future conditions.</FONT></FONT></P>
