                         ANNUAL MEETING OF SHAREHOLDERS
                            TO BE HELD JUNE 19, 2007

This Proxy Statement is furnished to the shareholders of ADA-ES, Inc. (the
"Company"), a Colorado corporation, in connection with the solicitation of
proxies by the Company's ("our") Board of Directors (the "Board"), to be voted
at our ANNUAL MEETING OF SHAREHOLDERS (the "Meeting") to be held on Tuesday,
June 19, 2007, at the Pinehurst Country Club at 6255 West Quincy Street, Denver,
Colorado and any postponements or adjournments thereof. This Proxy Statement and
accompanying form of proxy is first being mailed or given to our shareholders on
or about May 7, 2007. The shares represented by all proxies that are properly
executed and submitted will be voted at the Meeting in accordance with the
instructions indicated thereon, and if no instructions are given, then in the
discretion of the proxy holder. Throughout this Proxy Statement, the terms "we,"
"us" "our" and "our company" refer to ADA-ES, Inc., and unless the context
indicates otherwise, our subsidiaries on a consolidated basis.


                         VOTING RIGHTS AND VOTE REQUIRED

Our Board has fixed the close of business on April 30, 2007 as the record date
for determination of shareholders entitled to notice of and to vote at the
Meeting. At such date there were [____________] shares of our common stock
issued and outstanding (hereinafter referred to as the "Common Stock"), each of
which entitles the holder thereof to one vote on all matters that may come
before the meeting. We do not have any class of voting securities other than
Common Stock. An abstention or withholding authority to vote will be counted as
present for determining whether the quorum requirement is satisfied. If a quorum
exists, actions or matters other than the election of the Board are approved if
the votes cast in favor of the action exceed the votes cast opposing the action
unless a greater number is required by the Colorado Business Corporation Act or
our Articles of Incorporation. Abstentions will not affect the election of
directors, but will have the same effect as a vote against the proposals to
approve our 2007 Stock Incentive Plan and the Stock Issuance Plan. A broker
non-vote occurs when a nominee holding shares for a beneficial holder does not
have discretionary voting power and does not receive voting instructions from
the beneficial owner. Such nominees will not have discretionary voting power
with respect to approving our 2007 Stock Incentive Plan or the Stock Issuance
Plan. Broker non-votes on a particular proposal will not be treated as shares
present and entitled to vote on the proposal and accordingly will have no effect
on the vote.

A minimum of one-third of the shares of Common Stock issued and outstanding must
be represented at the Meeting, in person or by proxy, in order to constitute a
quorum. Cumulative voting is not allowed for any purpose. Assuming a quorum is
present, the nine nominees receiving the highest number of votes cast will be
elected as Directors.

Unless instructions to the contrary are marked, or if no instructions are
specified, shares represented by proxies will be voted:

     o    FOR the persons nominated by the Board for directors, being Robert N.
          Caruso, Michael D. Durham, John W. Eaves, Derek C. Johnson, Ronald B.
          Johnson, Mark H. McKinnies, Rollie J. Peterson, Jeffrey C. Smith and
          Richard Swanson.

     o    FOR the approval of the 2007 Equity Incentive Plan.

     o    FOR the approval of the Stock Issuance Plan for authorization to issue
          shares of the Company's common stock in excess of 20% of the amount of
          our outstanding shares of common stock and not more than 3 million
          shares, including shares of common stock underlying options and
          warrants, in connection with raising capital for implementing our
          business plan for being the market leader in mercury control
          technology by manufacturing injection equipment and activated carbon
          for our power plant customers. This includes possible acquisition of
          equipment fabricator(s) and development of a "Greenfield" activated
          carbon manufacturing facility or other projects or ventures intended
          to provide the Company and its customers with a long-term supply of
          activated carbon and working capital requirements.

We do not know of any other matter or motion to be presented at the Meeting. If
any other matter or motion should be presented at the Meeting upon which a vote
must be properly taken, the persons named in the accompanying form of proxy
intend to vote such proxy in accordance with that person's judgment, including
any matter or motion dealing with the conduct of the Meeting.

                                       3



Any shareholder who completes a proxy may revoke it at any time before it is
exercised by delivering written notice of such revocation to the Company (c/o
Mark H. McKinnies, Secretary), 8100 SouthPark Way, Unit B, Littleton, Colorado,
80120, by submitting a new proxy executed at a later date, or by attending the
Meeting and voting in person.

The Company will pay solicitation expenses. In addition to solicitation by mail,
our directors, officers and other employees may, without additional
compensation, solicit proxies by mail, in person or by telecommunication.

                              ELECTION OF DIRECTORS

At the Meeting, the shareholders will elect nine directors of the Company. Each
director will hold office until the next Annual Meeting of Shareholders and
thereafter until a successor is elected and has qualified. Cumulative voting is
not permitted in the election of directors. IN THE ABSENCE OF INSTRUCTIONS TO
THE CONTRARY, THE PERSON NAMED IN THE ACCOMPANYING PROXY WILL VOTE IN FAVOR OF
THE ELECTION OF THE FOLLOWING PERSONS NAMED AS OUR NOMINEES FOR DIRECTORS:
ROBERT N. CARUSO, MICHAEL D. DURHAM, JOHN W. EAVES, DEREK C. JOHNSON, RONALD B.
JOHNSON, MARK H. MCKINNIES, ROLLIE J. PETERSON, JEFFREY C. SMITH and RICHARD J.
SWANSON.

All of the nominees are currently members of the Board. Each of the nominees has
consented to be named herein and to serve if elected. It is not anticipated that
any nominee will become unable or unwilling to accept nomination or election,
but if such should occur, the persons named in the proxy intend to vote for the
election in his stead of such other person as the Board may recommend. It is the
policy and practice of the Company that all directors attend the Meeting. All of
our directors attended our 2006 Annual Meeting of Shareholders.

The following table sets forth certain information as to each current nominee
and director of the Company:

                                 PROPOSAL NO. 2

                     APPROVAL OF 2007 EQUITY INCENTIVE PLAN


Our shareholders are being asked to vote on the proposed 2007 Equity Incentive
Plan (the "Plan") in order to provide us with a means to attract and maintain
the best possible personnel, to provide additional incentives to employees,
directors and consultants, and to promote the success of the Company's business.
We currently have nine directors and approximately 40 employees and 6
consultants who will be eligible to participate in the Plan. We are proposing to
replace our existing 2003 Stock Option Plan with the Plan, which will provide us
with needed flexibility in tailoring equity compensation awards that we expect
will assist us in securing and retaining key personnel needed for our business.


General Description

The Plan permits grants of "Awards," which include the grant of (1) options to
purchase Common Stock ("Options") and (2) "restricted" shares of Common Stock
("Restricted Stock"). Under the Plan, incentive stock options ("ISO's"), within
the meaning of Section 422 of the Internal Revenue Code (the "Code"), can be
granted only to our employees or employees of any parent or subsidiary
corporation. Non-qualified stock options ("NSO's") and Restricted Stock may be
granted to employees, directors and consultants. An Award may include any
combination of Options or Restricted Stock.

The Plan provides for the grant of Options with exercise terms that will include
a fixed exercise price (i.e., the price an optionee must pay for the stock
issued on exercise of the Option) which will be related to the market price of
our Common Stock on the date of grant. The exercise price will generally be no
less than the fair market value of the Common Stock at that time, except in the
case of owners of 10% or more of our Common Stock at the time of a grant, in
which case the exercise price will be no less than 110% of the per share fair
market value of the Common Stock. In addition, Awards of Options and Restricted
Stock will be subject to a vesting schedule or, in the case of Restricted Stock,
a "reverse" vesting schedule, which will be based on the passage of time, the
occurrence of one or more events or the satisfaction of performance criteria or
other conditions. The market value of our shares of common stock as of April 30,
2007 was $ __________.

Under the Plan, we may grant Awards to such employees, directors or consultants
who are residing in foreign jurisdictions as the administrator of the Plan may
determine from time to time. The Plan is not a qualifying deferred compensation
plan under Section 401(a) of the Code and is not subject to the provision of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").

Our Plan was approved by our Board of Directors on April 6, 2007; however, the
Plan is subject to approval by our shareholders, which is being sought under
this Proposal at this meeting .


Shares Reserved

The number of shares of Common Stock authorized for issuance under the Plan will
be limited to not more than 1 million shares, which includes shares of Common
Stock that may be issued upon exercise of Options or as Restricted Stock issued
under the Plan. Initially, the number of shares reserved for issuance of Awards
under the Plan will be 600,000, with an "evergreen" provision pursuant to which
additional shares will automatically be added to the Plan on the first day of
each fiscal year, beginning with the fiscal year commencing January 1, 2008, in
an amount equal to ten percent (10%) of the increase in the total number of
shares of Common Stock outstanding on the last day of the immediately preceding
fiscal year over the number of outstanding shares of Common Stock on such date
one year prior, or such lesser number of shares as is later ratified by the
Board at their first meeting or action in such new fiscal year. In no event may
any annual increase exceed 300,000 shares and in no event can the total number
of shares authorized for issuance under the Plan exceed 1,000,000.


Administration

The Plan will be administered by a "Plan Administrator," which may be the Board
of Directors or a committee designated by the Board in such a manner as to
satisfy applicable laws. It is anticipated that the Compensation Committee of
the Board will administer the Plan. With respect to grants to directors or
employees who are also officers or directors of the Company, the administration
shall permit such grants and related transactions under the Plan to be exempt
from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. With
respect to awards subject to Section 162(m) of the Internal Revenue Code of 1986
(the "Code"), the committee will be comprised solely of two or more "outside
directors" as defined under Section 162(m) and applicable tax regulations. For
grants of awards to individuals not subject to Rule 16b-3 and Section 162(m),
our Board may authorize one or more officers to grant such awards.

                                       6




Limitations on Award Grants

The maximum number of shares of Common Stock that may be granted as to an Award
to any grantee in any fiscal year is limited to 30,000 shares, except for
Non-Management Directors, who may only be granted annual Awards covering up to
10,000 shares. However, in connection with his or her initial commencement of
services with us, a participant in the Plan who is an employee may be granted up
to an additional 30,000 shares, which do not count against the limit set forth
in the previous statement. These limitations ensure that any Options granted
under the Plan qualify as "performance-based compensation" under Section 162(m)
of the Code. Under Code Section 162(m) no deduction is allowed in any taxable
year for compensation in excess of $1 million paid to our chief executive
officer and each of our four most highly paid other executive officers who are
serving in such capacities as of the last day of such taxable year. An exception
to this rule applies to compensation that is paid pursuant to a stock incentive
plan approved by our shareholders and that specifies, among other things, the
maximum number of shares with respect to which options may be granted to
eligible employees under such plan during a specified period. Compensation paid
pursuant to options granted under such a plan and with an exercise price equal
to the fair market value of our Common Stock on the date of grant is deemed to
be inherently performance-based, since such awards provide value to employees
only if the stock price appreciates. If the Plan did not contain the Code
Section 162(m) share limits with respect to which options may be granted to
eligible employees during a specified period, any compensation expense
associated with the Options granted under the Plan in excess of $1 million for
any of our five highest paid officers would not be deductible to us under the
Code.


Amendment and Termination

Our Board of Directors may at any time amend, suspend or terminate the Plan. To
the extent necessary to comply with applicable provisions of federal securities
laws, state corporate and securities laws, the Code, the rules of any applicable
stock exchange or national market system and the rules of any foreign
jurisdiction applicable to awards granted to residents therein, we will obtain
shareholder approval of any amendment to the Plan in such a manner and to such a
degree as required.

If approved by the shareholders, the Plan will terminate as of June 18, 2017,
ten years from the date the Plan was approved by our Board of Directors, unless
previously terminated by the Board.


Termination of 2003 Stock Option Plan Upon Shareholder Approval of the Plan

If the Plan is approved by our shareholders, we will terminate our 2003 Stock
Option Plan, under which there remain 140,706 shares of Common Stock reserved
for the grant of new options under the 2003 Stock Option Plan.


Other Terms of Options

Options granted under the Plan and the rights and privileges evidenced by any
Option may not be transferred, assigned, pledged or hypothecated in any manner
(whether by operation of law or otherwise) other than (i) by will or by the
applicable laws of descent and distribution, (ii) pursuant to a qualified
domestic relations order as defined in Section 414(p) of the Code, or Title I of
the Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder or (iii) as otherwise determined by the Plan Administrator and set
forth in the applicable Option agreement. Any attempt to transfer, assign,
pledge, hypothecate or otherwise dispose of any Option under the Plan or of any
right or privilege conferred thereby, contrary to the Code or to the provisions
of the Plan, or the sale or levy or any attachment or similar process upon the
rights and privileges conferred thereby shall be null and void. The designation
by an Optionee of a beneficiary does not, in and of itself, constitute an
impermissible transfer under the Plan.

If the Optionee's relationship with the Company or any related corporation
ceases for any reason other than termination for cause, death or total
disability, and unless by its terms the Option sooner terminates or expires,
then the Optionee may exercise, for a three-month period, that portion of the
Optionee's Option which is exercisable at the time of such cessation, but the
Optionee's Option shall terminate at the end of the three-month period following
such cessation as to all shares for which it has not theretofore been exercised,
unless, in the case of an NSO, such provision is waived in the agreement
evidencing the Option or by resolution adopted by the Plan Administrator within
90 days of such cessation. If, in the case of an ISO, an Optionee's relationship
with the Company or related corporation changes (i.e., from employee to
non-employee, such as a consultant), such change shall constitute a termination
of an Optionee's employment with the Company or related corporation and the
Optionee's ISO will become an NSO.

                                       7



Options under the Plan must be issued within 10 years from the effective date of
the Plan which is expected to be on June 19, 2007 if our shareholders approve
the adoption of the Plan. Options granted under the Plan cannot be exercised
more than 10 years from the date of grant. Options issued to a 10% Shareholder
are limited to five-year terms.

Payment of the option exercise price shall generally be made in full at the time
the notice of exercise of the Option is delivered to the Company and shall be in
cash, bank certified or cashier's check or personal check (unless at the time of
exercise the Plan Administrator in a particular case determines not to accept a
personal check). The Plan Administrator can determine at the time the Option is
granted for ISO's, or at any time before exercise for NSO's, that additional
forms of payment will be permitted. To the extent permitted by the Plan
Administrator and applicable laws and regulations (including, but not limited
to, federal tax and securities laws and regulations and state corporate law), an
Option may be exercised by delivery of shares of stock of the Company held by an
Optionee having a fair market value equal to the exercise price, such fair
market value to be determined in good faith by the Plan Administrator; delivery
of a properly executed exercise notice, together with irrevocable instructions
to a broker, all in accordance with the regulations of the Federal Reserve
Board, to promptly deliver to the Company the amount of sale or loan proceeds
necessary to pay the exercise price and any federal, state or local withholding
tax obligations that may arise in connection with the exercise; or delivery of a
properly executed exercise notice together with instructions to the Company to
withhold from the shares that would otherwise be issued upon exercise that
number of shares having a fair market value equal to the option exercise price.

Any unexercised Options that expire or that terminate upon an employee's ceasing
to be employed by the Company, or shares of Restricted Stock that are
repurchased by the Company become available again for issuance under the Plan.

The vesting of outstanding Options under the Plan will be subject to
acceleration upon certain changes in the ownership or control of the Company.
The acceleration of the vesting of Options in the event of such changes in
control may be seen as an anti-takeover provision and may have the effect of
discouraging a merger proposal, a takeover attempt or other efforts to gain
control of the Company.

If the Grantee is an officer, director or owner of greater than 5% of our Common
Stock at such time, and if we so request and a lead underwriter of any public
offering of our Common Stock demands, the Grantee will agree not to sell,
contract to sell, grant any option to purchase, transfer the economic risk of
ownership in, make any short sale of, pledge or otherwise transfer or dispose of
any interest in any of our Common Stock or any securities convertible into or
exchangeable or exercisable for or any other rights to purchase or acquire
Common Stock (except Common Stock included in such public offering or acquired
on the public market after such offering) during the 180-day period following
the effective date of a registration statement filed under the Securities Act of
1933, as amended, or such shorter period of time as the Lead Underwriter may
specify.


Other Terms Applicable to Restricted Stock

We may award Restricted Stock under the Plan on terms determined by the Plan
Administrator at the time of grant. Generally, we will issue shares of
Restricted Stock to a grantee at a price (the "Purchase Price") which the Plan
Administrator determines at the time of grant. The shares are then classified as
"Restricted Shares," and are subject to our right to repurchase them as set
forth on a schedule to the Restricted Stock Agreement entered into between us
and the grantee, under which we lose our repurchase rights, and the shares are
no longer classified as "Restricted Shares." The number of shares as which our
repurchase rights lapse will generally be determined by the passage of time, but
may also be based on the happening of a specified event, such as the attainment
of some predetermined performance criteria or a change in corporate ownership or
control. The Plan Administrator will have discretion in determining the schedule
and/or the events that will specify the terms and conditions of the Company's
repurchase rights. Restricted Shares are required to be placed in escrow with us
until such time as our repurchase rights lapse. We will generally be entitled to
exercise our repurchase rights at any time within 90 days of the grantee's
cessation of "Continuous Service" with the Company by paying an amount equal to
the price paid by the grantee for the Restricted Shares.

If the Grantee is an officer, director or owner of greater than 5% of our Common
Stock at such time, and if we so request and a lead underwriter of any public
offering of our Common Stock demands, the Grantee will agree not to sell,
contract to sell, grant any option to purchase, transfer the economic risk of
ownership in, make any short sale of, pledge or otherwise transfer or dispose of
any interest in any of our Common Stock or any securities convertible into or
exchangeable or exercisable for or any other rights to purchase or acquire
Common Stock (except Common Stock included in such public offering or acquired
on the public market after such offering) during the 180-day period following
the effective date of a registration statement filed under the Securities Act of
1933, as amended, or such shorter period of time as the Lead Underwriter may
specify.


Certain Federal Tax Consequences

The grant of an NSO under the Plan will not result in any federal income tax
consequences to the optionee or to us. Upon exercise of an NSO, the optionee is
subject to income taxes at the rate applicable to ordinary compensation income

                                       8




on the difference between the option exercise price and the fair market value of
the shares on the date of exercise. This income is subject to withholding for
federal income and employment tax purposes. We are entitled to an income tax
deduction in the amount of the income recognized by the optionee, subject to
possible limitations imposed by Section 162(m) of the Code. Any gain or loss on
the optionee's subsequent disposition of the shares will receive long-term or
short-term capital gain or loss treatment, depending on whether the shares are
held for more than one year following exercise. We do not receive a tax
deduction for any such gain.

The grant of an ISO under the Plan will not result in any federal income tax
consequences to the optionee or to us. An optionee recognizes no federal taxable
income upon exercising an ISO (subject to the alternative minimum tax rules
discussed below), and we receive no deduction at the time of exercise. The tax
consequences of a disposition of stock acquired upon exercise of an ISO depends
upon how long the optionee has held the shares. If the optionee does not dispose
of the shares within two years after the ISO was granted, nor within one year
after the ISO was exercised, the optionee will recognize a long-term capital
gain (or loss) equal to the difference between the sale price of the shares and
the exercise price. We are not entitled to any deduction under these
circumstances.

If the optionee fails to satisfy either of the foregoing holding periods, he or
she must recognize ordinary income in the year of the disposition, which we
refer to as a disqualifying disposition. The amount of such ordinary income
generally is the lesser of (i) the difference between the amount realized on the
disposition and the exercise price, or (ii) the difference between the fair
market value of the stock on the exercise date and the exercise price. Any gain
in excess of the amount taxed as ordinary income will be treated as a long-term
or short-term capital gain, depending on whether the stock was held for more
than one year. We are entitled to a deduction equal to the amount of ordinary
income recognized by the optionee in the year of the disqualifying disposition.

The "spread" under an ISO, i.e., the difference between the fair market value of
the shares at exercise and the exercise price, is classified as an item of
adjustment in the year of exercise for purposes of the alternative minimum tax
calculation of the optionee.

The grant of restricted stock will subject the grantee to ordinary compensation
income on the difference between the amount paid for such stock and the fair
market value of the shares on the date that the restrictions lapse. This income
is subject to withholding for federal income and employment tax purposes. We are
entitled to an income tax deduction in the amount of the ordinary income
recognized by the grantee, subject to possible limitations imposed by Section
162(m) of the Code. Any gain or loss on the grantee's subsequent disposition of
the shares will receive long-term or short-term capital gain or loss treatment
depending on whether the shares are held for more than one year and depending on
how long the stock has been held since the restrictions lapsed. We do not
receive a tax deduction for any such gain.

Recipients of restricted stock may make an election under Section 83(b) of the
Code to recognize as ordinary compensation income in the year that such
restricted stock is granted the amount equal to the spread between the amount
paid for such stock and the fair market value on the date of the issuance of the
stock. If such an election is made, the grantee recognizes no further amounts of
compensation income upon the lapse of any restrictions and any gain or loss on
subsequent disposition will be long-term or short-term capital gain to the
grantee. An election under Section 83(b) must be made within 30 days from the
time the restricted stock is issued.

The foregoing is only a summary of the current effect of federal income taxation
upon the grantee and us with respect to the shares purchased under the Plan. You
should refer to the applicable provisions of the Code. In addition, the summary
does not discuss the tax consequences of a grantee's death or the income tax
laws of any municipality, state or foreign country to which the grantee may be
subject.


Plan Benefits

We have not issued or planned or committed to issue any Awards under the Plan as
of the date of this Proxy Statement. Assuming our shareholders approve the Plan,
and our 2003 Stock Option Plan is terminated, we expect to commence to use the
Plan for issuance of equity compensation as has been customary in the past.


Board Recommendation

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO APPROVE THE 2007
EQUITY INCENTIVE PLAN.

                                       9



                                 PROPOSAL NO. 3

    STOCK ISSUANCE PLAN - ISSUANCE OF SHARES OF THE COMPANY'S COMMON STOCK IN
   EXCESS OF 20% OF THE AMOUNT OF OUR EXISTING OUTSTANDING SHARES AND NOT MORE
       THAN 3 MILLION SHARES, INCLUDING SHARES OF COMMON STOCK POTENTIALLY
                UNDERLYING PREFERRED STOCK, OPTIONS AND WARRANTS


Background and Overview

We currently anticipate the likely need to raise additional capital to finance
our growth plans including the possible acquisition of an equipment
manufacturer, the development of a proposed activated carbon ("AC")
manufacturing facility and/or to fund the future expansion of an existing AC
manufacturing facility, as well as for general working capital purposes. Since
we believe we currently have the financial resources available internally to
fund the growth activities presently approved by the Board, we believe that it
would be beneficial for the Company to be positioned to raise capital for future
financing needs on an expedited basis in order to take advantage of the timing
of favorable market conditions, and may be on terms and conditions where the
issuance of the security is not restricted or otherwise limited upon issuance,
conversion or exercise. Because our common stock is listed for trading on the
NASDAQ Capital Market (formerly the NASDAQ Small Cap), the issuance of our
common stock, or securities that are convertible or exercisable into common
stock, is subject to the NASDAQ Marketplace Rules, including Rule 4350. Under
Rule 4350(i)(1)(B) and 4350(i)(1)(D), shareholder approval must be obtained when
(a) the issuance or potential issuance will result in a change of control of the
issuer (the "Change of Control Rule"); or (b) where the transaction is other
than a public offering and involves: (x) the sale, issuance or potential
issuance of common stock at a price less than the greater of book or market
value which, together with sales by officers, directors or substantial
shareholders of the issuer, equals 20% or more of the common stock or 20% or
more of the voting power outstanding before the issuance; or (y) the sale,
issuance or potential issuance of common stock equal to 20% or more of the
common stock (or of the voting power) outstanding before the issuance for less
than the greater of book or market value of the stock (the "20% Rule"). We are
therefore seeking your approval now for the issuance of common stock or
securities exercisable for or convertible into common stock that, absence such
approval, would violate the Change of Control Rule and/or the 20% Rule. If this
proposal is approved, we will be able to engage in a financing transaction or a
series of financing transactions in which we will be allowed to issue more than
20% of our outstanding common stock (as of the date prior to the newly
authorized issuance) but not more than a total of 3 million shares, either
directly, upon conversion of a preferred stock, or through the exercise of
warrants issued in that financing.


Potential Dilutive Effect on Existing Shareholders

Regardless of the type of security that is issued in connection with any future
capital raising efforts, it is anticipated that such security or securities will
constitute, either directly or by conversion or exercise, more than 20% of our
then issued and outstanding common stock and a total of not more than 3 million
shares and, accordingly, could be materially and substantially dilutive to our
existing shareholders. We currently anticipate raising up to $60 to 80 million
in new capital from a future financing or series of future financings, but the
terms of any such financing have not been determined at this time. However, we
would issue no more than 3 million shares of our common stock (either directly
or by the conversion of preferred stock and the exercise of warrants that would
be issued in connection with any such direct common stock or preferred stock
issuance or issuances. As a result, the maximum amount of dilution that may be
experienced by current shareholders would be an aggregate of 3 million shares of
common stock underlying the securities that may be issued in any such financing
or financings. It is currently anticipated that in connection with such
financing or series of financings, we will issue either common stock,
convertible preferred stock, warrants, or some combination thereof, which could
result in gross proceeds to us of up to $80 million in the aggregate, exclusive
of any proceeds we may receive upon exercise of warrants that may be issued in
such a financing. As it is anticipated that the future issuance price,
conversion price or exercise price, as applicable, will be determined in
relation to the market price of our common stock at the time of such issuance,
it is impossible to determine what that price will be at this time. Accordingly,
we can only provide you with information based upon the maximum amount of
dilution you would experience in the event the maximum number of shares reserved
for such purposes were issued in any such future financing or financings.
Finally, in order to provide our existing shareholders with as much dilution
protection as possible, the price per share, conversion price or exercise price,
as applicable, will not be greater than a 10% discount to the market price of
our common stock at such time.


Use of Proceeds from the Financing

As described in detail in our Annual Report on Form 10-K, we develop and
implement proprietary environmental technology and provide specialty chemicals
that enable coal-fueled power plants to enhance existing air pollution control
equipment, maximize capacity and improve operating efficiencies. As a part of

                                       10



this business, we are actively involved in designing, marketing and supplying
mercury emissions control systems to coal-fueled power plants. A key compound
used in the mercury emissions control systems we provide is powdered activated
carbon ("AC"), which is typically injected in the ductwork after the boiler and
acts to reduce mercury emissions from the flue gas. An important aspect of this
part of our business requires that we be able to supply our customers with an
adequate supply of activated carbon meeting standards required for effective
mercury emissions reduction, and we have devoted substantial resources to be
able to do so. We believe that the existing and available supply of AC needed
for the developing mercury emissions control ("MEC") market will be unable to
meet the demand for the material as early as 2010. We commissioned a market
study from a third party to address the current worldwide production and
expected future demand for activated carbon in both the conventional water
treatment markets and the developing MEC market. This study documented that the
current U.S. market for activated carbon, which is primarily for water
treatment, is approximately $200 million per year. With regulations in place
today to reduce mercury emissions, this could more than double by 2010, and in
addition, if a more stringent federal regulation comes into effect, the demand
could more than triple by that time. As a result, we have been investigating the
possibility of either purchasing an existing AC facility or developing a new
"Greenfield" facility to manufacture activated carbon. We are currently pursuing
plans to develop a new "Greenfield" facility, while exploring the parallel
possibility of entering into a collaborative project with an existing AC
manufacturer to increase capacity. We have committed approximately $4 million
for the preparatory phase of this project through August, 2007, including plant
location, design and permitting, as well as determining and sourcing key capital
equipment that would be required for such a facility. A large-scale production
facility, which is expected to cost in excess of $200 million to develop, and
which will have the capacity to produce approximately $100 million worth of
activated carbon per year, is being designed to maximize efficiency and produce
the most cost-effective product for the MEC market. Such a project will require
supplementary financing, and we anticipate that financing will involve a
combination of equity and debt funding from financial and strategic partners. As
a result, and if the Board determines to move ahead with the project after the
current preparatory phase, we would expect to use the gross proceeds from the
financing for which approval is being sought hereby to finance the development
of a proposed AC manufacturing facility or to fund the future acquisition of an
existing AC manufacturing facility, as well as for general working capital
purposes. For near-term AC supplies, ADA-ES and Calgon Carbon Corporation have
signed a MOU to explore working closely together on both a marketing and product
development basis, which is intended to result in a formal joint marketing
agreement to address the ever increasing MEC market, within the next few several
months.


Necessity for Shareholder Approval

NASDAQ Marketplace Rule 4350 includes both the Change of Control Rule and the
20% Rule. Our Amended and Restated Articles of Incorporation allows us to issue
both common stock and preferred stock as to which the Board can designate the
rights, preferences and privileges of any series of such preferred stock.
However, unless the securities are issued in a public offering, the issuance of
common stock or the conversion of any such preferred stock that has a conversion
price below the market price on the date of issuance must comply with the 20%
Rule, or if the conversion price is at or above market and the conversion would
result in the issuance of greater than 20% of the outstanding common stock on a
post-conversion basis, such issuance must comply with the Change of Control
Rule. Although we do not yet know the price of the securities to be offered in a
future financing or series of financings, we are seeking shareholder approval at
this time in order to be able to complete any such future financings in a timely
manner in order to allow us to take advantage of favorable market conditions or
heightened investor interest. Furthermore, we believe that the ability to issue
securities without restriction on the issuance, conversion or exercise thereof
will provide us with better leverage in negotiating the terms of any such future
financing with potential investors.

In order to enable the Company to issue common stock, or allow purchasers of
preferred stock or warrants to fully convert or exercise such securities, we
must comply with the shareholder approval requirements of either the 20% Rule
for any anticipated financing (other than in a public offering) where we propose
to issue securities at a price below existing market, or the Change of Control
Rule for any anticipated financing where we propose to issue securities at a
price at or above market. We do not have terms, including the price of the
securities issuable pursuant to the proposed financing, at this time, although
the maximum amount of common stock or securities convertible into common stock
discussed above will be the maximum amount of dilution experienced by our
current shareholders as a result of any such issuance.


Recommendation

The Board believes that it is in the Company's best interest for the
shareholders to authorize the issuance of securities in a subsequent financing
or series of financings as described herein, so that the Company can take
advantage of market conditions and raise capital as needed to fund the Company's
expansion plans.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO APPROVE THE
ISSUANCE OF ADDITIONAL SHARES IN EXCESS OF 20% OF THE AMOUNT OF OUTSTANDING
SHARES.

                                       11




                               BOARD OF DIRECTORS

Our Board is responsible for establishing broad corporate policies and
monitoring the overall performance of the Company. However, in accordance with
corporate legal principles, the Board is not involved in day-to-day operating
matters. Members of the Board are kept informed of the Company's business by
participating in Board and committee meetings, by reviewing analyses and reports
sent to them each month, and through discussions with the President and other
officers.

                                BOARD COMMITTEES

The Board maintains audit, compensation and nominating and governance
committees. In calendar 2006 each committee was composed of directors who
qualify as "independent directors" as defined in NASD Rule 4200(a)(15). The
charters of each committee are available on our website at www.adaes.com under
"Investor Relations."

                                 AUDIT COMMITTEE

Our Board has an Audit Committee established in accordance with Section
3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), which consists of Messrs. Derek Johnson, Ronald Johnson, Peterson, Smith
and Swanson. Mr. Swanson serves as the chairman of the Audit Committee. Our
Board has determined that Mr. Swanson is an Audit Committee Financial Expert.
Mr. Swanson is "independent" as that term is used in Item 7(d)(3)(iv) of
Schedule 14A under the Exchange Act.

The role and functions of the Audit Committee are set out in the Audit Committee
Charter, as amended, originally adopted by the Company's Board and most recently
amended on September 23, 2005. The role of the Audit Committee is one of
oversight of our accounting and financial reporting processes and audits of our
financial statements. The Audit Committee's functions include the following:
reviewing and assessing the Audit Committee Charter annually; reviewing the
Company's relationships with its outside auditors and assessing the impact such
relationships may have on the auditors' objectivity and independence; taking
other appropriate action to oversee the independence of the outside auditors;
reviewing and considering the matters identified in Statement on Auditing
Standards No. 61 with the outside auditors and management; reviewing and
discussing the Company's financial statements with the outside auditors and
management; recommending whether the Company's audited financial statements
should be included in the Company's Form 10-K for filing with the Securities and
Exchange Commission ("SEC"); and reporting to the Board on all such matters. In
performing its oversight function, the Audit Committee relies upon advice and
information received in its discussions with the Company's management and
independent auditors.


                          Report of the Audit Committee

The Audit Committee has (i) reviewed and discussed the Company's audited
financial statements for the fiscal year ended December 31, 2006 with the
Company's management; (ii) discussed with the Company's independent auditors the
matters required to be discussed by Statement on Auditing Standards No. 61, as
amended, as adopted by the Public Company Accounting Oversight Board ("PCAOB")
in Rule 3200T regarding communication with audit committees (AICPA Professional
Standards, Vol. 1, AU section 380); and (iii) received the written disclosures
and the letter from the Company's independent accountants required by
Independence Standards Board Standard No. 1 (Independence Discussions with Audit
Committees), as adopted by the PCAOB in Rule 3600T, and has discussed with the
Company's independent accountants the independent accountants' independence.

Based on the review and discussions with management and the Company's
independent auditors referred to above, the Audit Committee recommended to the
Board that the audited consolidated financial statements as of December 31, 2005
and 2006 and for the years ended December 31, 2004, 2005 and 2006 be included in
the Company's Annual Report on Form 10-K for the fiscal year ended December 31,
2006 for filing with the SEC.

The Audit Committee:         Richard Swanson, Chairman        Derek Johnson
                             Ronald Johnson                   Rollie J. Peterson
                             Jeffrey C. Smith


                       NOMINATING AND GOVERNANCE COMMITTEE

Our Board has appointed a Nominating and Governance Committee consisting of
Messrs. Caruso, Eaves, Derek Johnson and Peterson. Mr. Peterson serves as the
chairman of the Nominating and Governance Committee. The responsibilities of the
Committee, as set forth in the Nominating and Governance Committee Charter,
include selecting director nominees for the Board, reviewing director
compensation and benefits and submitting to the entire Board for approval,
overseeing the annual self-evaluation of the Board and its committees,

                                       12




recommending the structure and composition of Board committees to the entire
Board for approval and monitoring in conjunction with the Audit Committee
compliance with our Code of Conduct and granting any waivers thereto with
respect to directors and executive officers. Criteria established for the
selection of candidates for the Board include:

     a.   An understanding of business and financial affairs and the
          complexities of an organization that operates as a public company in
          the business of the Company;
     b.   A genuine interest in representing all of our shareholders and the
          interests of the Company overall;
     c.   A willingness and ability to spend the necessary time required to
          function effectively as a director;
     d.   An open-minded approach to matters and the resolve and ability to
          independently analyze matters presented for consideration;
     e.   A reputation for honesty and integrity that is above reproach;
     f.   Any qualifications required of independent directors by the Nasdaq
          Stock Market and applicable law; and
     g.   As to any candidate who is an incumbent director (who continues to be
          otherwise qualified), the extent to which the continuing service of
          such person would promote stability and continuity in the Boardroom as
          a result of such person's familiarity and insight into the Company's
          affairs, and such person's prior demonstrated ability to work with the
          Board as a collective body.

Director nominees are generally identified by our officers, directors or
shareholders based on industry and business contacts. Regardless of the source
of the nomination, nominees are interviewed and evaluated by the Nominating and
Governance Committee, and other members of the management team or board of
directors as deemed appropriate by the Nominating and Governance Committee. The
Nominating and Governance Committee then presents qualified candidates to the
Board for a final discussion and vote.

Under the Nominating and Governance Committee Charter, the Nominating and
Governance Committee will consider nominees submitted by our shareholders.
Recommendations of individuals that meet the criteria set forth in the
Nominating and Governance Committee Charter for election at our 2008 annual
meeting of shareholders may be submitted to the Committee in care of Mark H.
McKinnies, Secretary, at 8100 SouthPark Way, Unit B, Littleton, Colorado 80120
no later than January 5, 2008.

The Committee has recommended to our Board the slate of directors for this
Annual Meeting as set forth above. No third party was used in identifying or
evaluating nominees and we received no shareholder recommendations for nominees.

                             COMPENSATION COMMITTEE

Our Board has appointed a Compensation Committee consisting of Messrs. Caruso,
Eaves, Ronald Johnson, Swanson and Smith. Mr. Johnson serves as the chairman of
the Compensation Committee. The responsibilities of the Compensation Committee,
as set forth in the Compensation Committee Charter, include reviewing our
executive compensation programs to analyze their alignment with attracting,
retaining and motivating our executive officers to achieve our business
objectives; establishing annual and long-term performance goals for our
executive officers and evaluating their performance in light of such goals,
reviewing and making recommendations concerning our long-term incentive plans
and shareholder proposals related to compensation and administering our
equity-based and employee benefit plans. See "Executive Compensation -
Compensation Discussion and Analysis" below for additional information.

                    DIRECTORS MEETINGS AND COMMITTEE MEETINGS

The Board of Directors met 11 times in 2006. At each of the regularly scheduled
bi-monthly meetings an Executive Session is held where management of the Company
is excluded. The Audit Committee met 9 times in 2006. The Compensation Committee
met 8 times in 2006 and the Nominating and Governance Committee met 6 times in
2006. All of the incumbent directors, other than Mr. Swanson due to travels out
of the country, were present for more than 75% of the meetings of Board of
Directors and committees of which they were members held during their individual
terms.

                     SHAREHOLDER COMMUNICATIONS TO DIRECTORS

Any shareholder may communicate directly with the Board (or any individual
director) by writing to the Chairman of the Board, ADA-ES, Inc., 8100 SouthPark
Way, Unit B, Littleton, Colorado 80120 or by emailing the Board through the
"Contact the Board" link on our website at www.adaes.com. Any such communication
should state the number of shares beneficially owned by the shareholder making
the communication. Provided that such communication addresses a legitimate
business issue, the Company or the Chairman will forward the shareholder's
communication to the appropriate director. For any communication relating to
accounting, auditing or fraud, such communication will be forwarded promptly to
the Chairman of the Audit Committee.

                             EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Our philosophy for executive compensation is set forth in a document entitled
"ADA-ES Executive Compensation Plan" (the "EC Plan") which was adopted by the
Board on November 4, 2004. The EC Plan applies to the Executive Team, which
includes the President/Chief Executive Officer, the Chief Operating Officer, the
Chief Financial Officer, and all Vice Presidents of the Company. Executives
become eligible to participate in this plan after completing 12 months of
continuous service with ADA-ES. This may be modified based on Board's approval.

The ADA-ES compensation philosophy was designed to support our goals in creating
a reputation that can be leveraged to build our business and reward
shareholders, executives and employees. The business goals include: creating a
steady stream of new and profitable products; developing sustainable, return
business; becoming the first company called for pollution control jobs; becoming
a household name in the utility industry; and ensuring a reputation for
outstanding service and value to customers. Compensation goals include: linking
the interests of shareholders with the interests of executives; maintaining a
reliable link to the market; giving the organization access to quality
candidates; and providing pay recognition for executives as a result of business
success.

Executive compensation decisions are based on these considerations:



-------------------------------------------------------------- ------------------------------------------------------
                    Leveraged Reputation                                        Quantitative/Qualitative

Executive compensation generally consists of three elements: base salary,
performance incentives and equity awards. Presently, all compensation is paid
out currently and we do not have any long-term plans related to compensation.
The Compensation Committee does not have specific policies for allocating
between cash and non-cash compensation.

The Compensation Committee establishes the level of pay for all executive
officers. The CEO makes recommendations as to compensation of other executive
officers to the Committee. Base salary is defined as ongoing, cash compensation
paid bi-weekly based on such factors as job responsibilities, external
competitiveness, and the individual's experience and performance. Pay ranges
will be set based on the local market for similar positions, with consideration
given to national rates of pay. Base salary is typically increased annually
based on cost of living increases. The Compensation Committee approved an
additional increase in the compensation of the Chief Operating Officer in 2007
based on comparable rates of pay in the market for her position and those
employees who report to her. ADA-ES will attempt to ensure middle market pay for
solid performers and consider higher levels of pay for outstanding performers.
ADA-ES does not intend to be a market leader in base compensation. A decision to
materially increase or decrease compensation would be based on the
aforementioned factors. Any gains or losses that might have been realized from
prior option awards are not considered in establishing current compensation
levels. The Compensation Committee engaged Mountain States Employers Council
(MSEC) to assist in the design and application of the EC Plan. MSEC advised on
the appropriateness of bonus levels for executive positions and provided
assistance in setting the weight for metrics and in modeling the EC Plan. We
also use compensation survey information from MSEC to determine appropriate pay
ranges. We do not benchmark compensation based on any reports.


                                       16



Annual incentives are designed to motivate the management team to achieve
critical short-term goals, typically one to two years, which are expected to
contribute to the long-term health and value of the organization. Incentives may
be paid in cash or equity as determined by the Board. It is expected that in the
early years of the plan, payment will be primarily in stock, either through
options or restricted shares.

Incentive amounts will be set based on organization level and market practices.
The plan will focus on specific business objectives set at the beginning of each
year. Objectives will be those quantitative metrics, such as revenue, income, or
market share, which management and the Board determine are most important to the
short and long term health and value of the organization. Potential incentive
amounts for 2005 and 2006 performance were established at 50% and 40% of base
salary for the CEO and other members of the executive team, respectively. In
2004, we adopted the Executive Stock Option Plan (the "2004 ESO Plan") discussed
below, and granted all 200,000 options authorized under such plan to our then
five executive officers, expecting to utilize the acceleration of vesting of
such options, for so long as they are available, as the means for the next
several years to pay any incentive amounts earned by the executive officers
pursuant to the EC Plan who are also covered in the 2004 ESO Plan. To determine
the value of each vested option share considered for accelerated vesting, the
exercise price of $8.60 per share, which was the fair value on the date of
grant, was subtracted from the average closing stock price for the month of
December of that year (i.e. $22.39, $16.42 and $15.98 for 2004, 2005 and 2006,
respectively). As a result, for the fiscal years 2004, 2005 and 2006 a total of
27,080, 38,428 and 17,258, respectively, of options were vested in payment of
incentive amounts earned for those years. Of the original 200,000 options
granted under the 2004 ESO Plan, 117,234 options remain available for vesting
for future incentive payments. We have not granted options to the executive
officers who received options under the 2004 ESO Plan since 2004. We generally
grant options to new hires at the Board meeting following the commencement of
employment. Mr. Miller was awarded 13,000 options at the Board meeting following
his date of hire in December 2005 under the 2003 Plan described below. Our
share-based compensation, including options granted under the 2003 Plan and the
2004 ESO Plan, is accounted for under the Statement of Financial Accounting
Standards No. 123R (See Footnote 1 to the Consolidated Financial Statements
included in Item 8 of our Form 10-K for the year ended December 31, 2006).

Options granted under the 2004 ESO Plan are considered non-qualified stock
options ("NQSO"). A recipient is required to pay ordinary income tax on the
difference, or "spread," between the grant price and the stock's market value
when he purchases ("exercise") the shares. A loss may not be recognized if the
grant price is greater than the exercise price. The greater of the grant price
or the market value at the exercise date (the amount used for calculating the
amount of ordinary income to be taxed, if any) becomes the tax basis of the
stock for calculating future gains and losses upon disposition or transfer of
the stock. A disposition of NQSO stock generally refers to any sale, exchange,
gift or transfer of legal title of stock, including a transfer from a decedent
who held NQSO stock to an estate, a transfer by a bequest or inheritance, or any
transfer of NQSO stock between spouses or incident to a divorce. Any subsequent
appreciation or decline in the stock is taxed at capital gains/loss rates when
the stock is disposed of. If the NQSO stock is held for more than a year, the
long-term capital gain/loss rate will apply. If the NQSO stock is held for one
year or less, any gain or loss is short-term and generally taxed as ordinary
income. The Compensation Committee chose NQSOs as the means for the next several
years to pay any incentive amounts earned by the executive officers pursuant to
the EC Plan because it believed such options aligned the interests of the
executive officers with the interest of our shareholders, provided potential
additional value from appreciation and allowed the recipient to determine the
timing of tax consequences from the award.

Specific metrics to measure executive performance for 2006 were established in
January 2006 and are shown in the following table. Performance metrics for 2007
were established in January 2007. The Compensation Committee discussed the 2006
performance metric to determine if changes were needed for 2007. The discussion
centered on the appropriateness of the metrics and the weighting. It was
determined that the definition of income should be changed to reflect income
from operations rather than net income from all sources. It was further
determined that the income metric should have greater weight to balance the
importance of revenue and income. Also, in determining the appropriate merit
increase level, we have begun to look at the actual market change for various
job families in addition to published local CPI-U data. The market change is
determined by tracking the year-over-year change in the median rate for a given
position or job family using local salary surveys.

The metrics include both objective (i.e. revenue growth, net income and stock
price appreciation) and more subjective (i.e. market share, industry and
customer relations) measurements. For the most part the objective goals are
measured against the Company's approved budget. Management considered all of the
goals established for 2006 as aggressive but attainable stretch goals. The
actual earned percentage of the potential incentive amounts for 2006 was
determined based on the following table that translates the measured metric
performance. The incentive scale table for 2007 has not been established. As
shown in the table, no incentive is paid for performance below 75% and as much
as 130% of the potential incentive amount may be paid for performance of 110% of
the goals. For 2006, performance measured by the metrics was approximately 84%,
which, based on the table below, translates to an incentive percentage of
approximately 38%. Applying this percentage to the potential incentive amounts
for 2006 performance noted above of 50% and 40% of base salary for the CEO and
other members of the executive team, respectively, incentive payments for 2006
amounted to approximately 19% and 15% of base salary for the CEO and other
members of the executive team, respectively. For those executive officers
covered by the 2004 ESO Plan (all executive officers as of December 31, 2006
except Mr. Miller), such amounts were paid in 2007 by accelerated vesting of
options as discussed above. The incentive amount earned by Mr. Miller was paid
in cash in 2007.

Annual incentives, if any, are approved for payment by the Compensation
Committee/Board of Directors and are planned for payment by February 28th of the
calendar year following the incentive period. Incentives paid in cash are
subject to payroll taxes. These incentives can be deferred and paid to a
designated beneficiary, although that has not been the case with any incentives
awarded thus far. The Compensation Committee/Board of Directors uses the
performance metrics as guidelines and may exercise discretion in determining
incentives awarded. In prior years, the Compensation Committee/Board of
Directors has elected to increase individual incentives awarded for specific
performance beyond that measured by the metrics. For 2006, the Compensation
Committee/Board of Directors elected to exclude the costs associated with the
sale of the joint venture interest to NexGen in the determination of the net
income before tax metric given that the $1,000,000 payment for such interest was
recognized as an equity transaction rather than revenue.

From time to time the Board of Directors may feel it necessary to recognize
exemplary performance of any executive with a cash award. Exemplary performance
will be performance that the Board determines to have required significant
effort and commitment and is determined to have had a significant positive
impact on the current or future performance of the organization. No such
payments were made in 2006.

The use of equity payments, such as using accelerated vesting of options granted
under the 2004 ESO Plan to make incentive payments, is intended to link
short-term success to long-term performance and decision making, and to align
management and shareholder interests. Payments may be made in restricted shares
or options, as determined by the Board, considering accounting and regulatory
restrictions, and the financial condition of the Company. No equity awards were
made in 2006; however, vesting on previously granted stock options was
accelerated for incentives earned in 2006 as noted above and as shown below in
the "Option Exercises and Stock Vested During Year Ended 12/31/06" table.

There is no severance pay policy or other benefits payable after termination for
any executive. See "Employment Contracts and Termination of Employment and
Change-in-Control Arrangements" below regarding executives' obligations after
termination.

In the event of a restatement of income, any over-payments made to executives
may be reclaimed at the discretion of the Board of Directors.

                                       18



In 2006 we obtained key man term insurance for our CEO, COO and CFO in the
amount of $2 million for each individual. The policies may be assigned to the
individuals upon termination of employment other than for cause whereupon the
executive would be responsible for any premium payments.

Executives are encouraged to own a number of shares of stock equal to a value of
at least one (1) times the annual base salary as a condition of continued
employment with ADA-ES. Executives have five (5) years from the later of
November 4, 2004 (the date the EC Plan was adopted) or the date of hire to
accomplish this level of ownership. Ownership is calculated considering holdings
of restricted stock, whether or not the restrictions have expired, private
holdings, and shares held in retirement accounts. Holding of options also will
be considered in the ownership calculation by adding the value of the spread of
in-the-money options to the total value of other holdings. No analysis was
performed for 2006 to see if encouraged ownership levels were met.

After ownership requirements have been met, executives may sell unrestricted
stock they have owned for a period greater than 12 months, and may not exercise
vested stock options and sell shares to pay for the exercise price and
withholding tax, except as otherwise provided for in the underlying stock option
agreement. The Company must be advised of any sale of stock options or shares of
stock at least 30 days in advance or be engaged in a pre-announced program sale
in compliance with federal securities laws, and such sales must be made in
compliance with our insider trading policy.

Executives leaving the company are required to hold their stock in the company
for at least 6 months after leaving the company.

Executives may also be eligible to participate in the Company's Profit Sharing
Plan ("PSP"). For fiscal 2006 the profit sharing pool was established as
twenty-four percent (24%) of net earnings before taxes, investment income and
certain other adjustments at the end of the fiscal year. In February 2007 the
Compensation Committee/Board of Directors approved a total payment of $147,000
for 2006 on reported net earnings and also approved an additional $100,000
discretionary bonus, which would have been earned under the PSP if the costs
associated with the sale of the JV interest to NexGen had been excluded for the
calculation of net earnings. The Committee/Board considered such exclusion
appropriate given the significance to the Company of the $1,000,000 payment
received from NexGen although such payment was not recognized as revenue. The
pool is expected to be distributed to our employees by no later than February
15th as follows:

    1. Retirement Plan (50%)
    2. Company-Wide Distribution (20%)
    3. Performance BasedDistribution (30%)

Retirement Plan (50%): This portion of the PSP is distributed among our
employees based on meeting the participation requirements in our current
qualified Retirement Plan described below. Individual distributions are
pro-rated as a percent of total compensation as required by the Retirement Plan.
The distribution may be made in either stock or cash at our Board of Director's
discretion. Vesting rules as outlined in the current PSP (described below) apply
for these distributions to employees. Employees with less than a year of service
and temporary employees, as defined in the PSP, are not eligible for this
portion of the pool.

Company-Wide Distribution (20%): This portion of the PSP is distributed evenly
among all of our full-time permanent employees with pro-rated distributions for
partial years of service. Employees terminated during the year forfeit
eligibility for this portion of the PSP. An early distribution of this portion
of the PSP was offered in December 2006 to those employees electing it.
Performance Based Distribution (30%): This portion of the PSP is distributed to
all of our permanent full-time and part-time employees on a performance-based
basis. Employees terminated during the year forfeit eligibility for this portion
of the PSP. Employees are evaluated semi-annually by their direct supervisor
based informally on criteria that may also be used in the formal performance
appraisal, which is generally conducted annually. The current criteria that may
be used for the evaluation includes, but is not limited to, job knowledge;
communications; attitude and cooperation; leadership; planning, judgment and
resourcefulness; and initiative and responsibility.

The following rating system is used for each criterion: 1 Point - Poor
Performance, 2 Points - Improvement Needed, 3 Points - Achieving Expectations, 4
Points - Exceeding Expectations, and 5 Points - Excellent Performance.

The employee's supervisor will complete the rating form, with input from project
managers or other personnel to whom said employee supports. Should an employee
receive an average rating for the two rating periods in 2006 of lower than 2.0,
the employee will not be eligible to receive any performance-based distribution.
Distributions are made based on the average rating and weighted by the
commercial rates that we would charge out an individual's time to customers in
effect at the end of the fiscal year.

                                       19



Amounts paid directly to the named executives for the performance-based portion
of the PSP are shown below in the Summary Compensation Table in the Bonus
column. The retirement plan and company-wide distributions paid from the PSP
pool are deposited to pension accounts under our Retirement Plan, a
tax-qualified defined contribution plan, and are included in the amounts shown
in that same table below in the All Other Compensation column.

Our Retirement Plan covers all eligible employees. Pursuant to that plan, we
make matching contribution to each eligible employee's account up to 5% of the
employee's eligible compensation, and may make, at the discretion of the Board
of Directors, contributions based on the profitability of the Company to those
accounts. Investments in an employee's account may be made in stocks, bonds,
mutual funds and other investments permitted by the Plan's administrator.

Employee contributions to the plan are 100% vested. Company contributions become
100% vested if an employee's employment ends after the date such employee
attains normal retirement age (age 65), dies or becomes disabled. If an
employee's employment is terminated prior to the date the employee attains
normal retirement age (65) or dies or becomes disabled, the employee will become
vested in the Company's matching contributions and any profit sharing
contributions pursuant to the PSP according to the schedule below:

         Less than 2                0%
         2                          20%
         3                          40%
         4                          60%
         5                          80%
         6 or more                  100%

The following table show compensation during the fiscal years ended December 31,
2006, 2005 and 2004, of those persons who were, at December 31, 2006, our
principal executive officer ("PEO"), principal financial officer ("PFO") and the
three most highly compensated executive officers other than the PEO and PFO
(collectively, "named executive officers" or "NEOs") of ADA-ES whose total
compensation exceeded $100,000. The structure of pay for each NEO is the same,
although as noted above the potential performance incentive amount for the PEO
was established at 50% of base pay for the years shown below and 40% for other
NEOs.

                       Nonqualified Deferred Compensation

Although our EC Plan allows for deferrals of payment, the Company does not
currently have any deferred compensation plans that apply to the NEOs.

               Employment Contracts and Termination of Employment
                       and Change-in-Control Arrangements

We have executed employment agreements with every full-time employee, including
our executive officers, which contain the following provisions:

     1.   Automatic extensions for one-year periods.
     2.   Three months' prior written notice of intent to terminate by either
          the Company other than for cause, death or permanent disability or the
          employee.
     3.   Description of position, duties, authority, compensation, benefits and
          obligation of the employee to devote full time to the fulfillment of
          his/her obligations under the agreement.
     4.   Obligations to disclose and Company ownership of inventions and
          confidential subject matter, which obligations survive for two years
          after termination of employment.
     5.   Assignment of inventions, obligations regarding inventions and
          confirmation of no Company obligation to commercialize inventions, all
          of which survive after termination of employment.
     6.   Acknowledgement that copyright works are "works for hire" and
          obligation of employee to maintain written records of all inventions
          and confidential subject matter.
     7.   Restrictive obligations relating to confidential subject matter, which
          survive after termination of employment.
     8.   Acknowledgement and agreement regarding no conflicting obligations and
          obligations upon termination of employment.

The compensation amounts included in the employment agreements are subject to
annual adjustment and the compensation levels for the named executive officers
are shown in the tables above. None of our employment contracts or 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 officer's employment with us or from a change-in-control of the
Company or a change in the named executive officer's responsibilities following
a change-in-control except as described below.

Under our stock incentive plans, unless otherwise provided in a stock option
agreement, options held by a director, executive or employee are exercisable
after such person's death or permanent disability without regarding to any
vesting requirements of such options.

                                       22



Upon, or in reasonable anticipation of, a change in control of the Company,
approved incentive compensation awards under the PSP may be made for the
incentive period during which the change in control occurs, and then paid
immediately to a trustee on such terms as our Chief Financial Officer deems
appropriate (including such terms as are appropriate to cause such payment, if
possible, not to be a taxable event to the executive). The incentive
compensation awards may be paid to executives either not later than the end of
the first calendar quarter following the end of the calendar year to which the
incentive compensation awards relate, or on a deferred basis in accordance with
the elections of the executives affected as to the timing of the receipt of
incentive compensation awards for such period. Executives who are eligible to
receive an incentive compensation award for the incentive period in which a
change in control occurs may be eligible to receive incentive compensation
awards for the incentive plan year following the change in control.

Guidelines for determining the amount of the incentive compensation award
payable to each executive include:

o    One-half of the maximum incentive compensation award payable (reduced as
     deemed appropriate by the Compensation Committee of the Board of Directors
     and approved by the Board of Directors, if applicable) to the executive if
     the change in control occurs during the first six months of the calendar
     year; or
o    The full maximum incentive compensation award payable (reduced as deemed
     appropriate by the Compensation Committee and approved by the Board, if
     applicable) to the executive if the change in control occurs during the
     second six months of the calendar year.

                          Compensation Committee Report

The Compensation Committee has reviewed the Compensation Discussion and Analysis
and discussed it with management. Based on its review and discussions with
management, the Committee recommended to our Board of Directors that the
Compensation Discussion and Analysis be included in this Proxy Statement and our
Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

The Compensation Committee:     Ronald Johnson, Chairman      Robert Caruso
                                John Eaves                    Richard Swanson
                                Jeffrey C. Smith

                              DIRECTOR COMPENSATION

Our Nominating and Governance Committee has responsibility for reviewing the
compensation plan for our non-management directors annually and making
recommendations to the entire Board for approval. In 2006, the Compensation
Committee conducted such analysis and made such recommendations. Neither
Committee has delegated authority to any other person to determine director
compensation. Our executive officers have not had any role in recommending the
amount or form of director compensation, but the two executive officers who
serve on our Board do vote on the recommendations for director compensation made
by the Committee to the Board. In the past, the Compensation Committee has
reviewed industry data from the Mountain States Employers Council and has sought
the input of representatives of such Council on its compensation structure and
amounts. Mountain States Employers Council has been engaged by the Compensation
Committee and was tasked with assisting in the design and application of the EC
Plan. MSEC advised on the appropriateness of incentive levels for executive
positions and provided assistance in setting the weight for metrics in modeling
the EC Plan.

In addition to the stock and option grants discussed below under "Stock
Incentive Plans," in 2006, prior to the changes described below, each
non-management director was paid a fee of approximately $600 per regular
meeting, $300 per committee or telephonic meeting or $500 per committee meeting
for serving as chairman of the committee. The Chairman of the Audit Committee
was paid the greater of $3,000 per month or an amount equal to hours worked
times an hourly rate.

In August 2006, the Compensation Committee recommended, and the Board approved,
a cost of living increase in director compensation of 3.5% over the previous
year to bring it more in line with industry standards. Prior to that date the
annual retainer due each non-management director was to be paid solely in stock
of not more than 1,000 shares of stock per year. Under the new plan, each
non-management director is entitled to receive an $18,000 per year retainer
payable in stock and cash commencing May 2006 or upon their commencement of
service, with a cap of 1,000 shares of stock per year, and options to acquire
5,000 shares of our common stock upon initial appointment or election to the
Board. Our directors also receive $1,000 per Board meeting and $500 per Board
Committee or telephonic Board meeting. In addition, the Chairman of the Board
and Chairman of the Audit Committee receive $3,000 per year, the Chairman of the
Compensation Committee receives $2,000 per year, and the Chairman of our
Nominating and Governance Committee receives $1,000 per year for their services
in such positions. These amounts are all paid in cash.

                                       23



In May 2006, the Company secured directors and officers insurance coverage for
its directors and executive officers. The annual cost of such coverage is
approximately $110,000.

                Director Compensation During Year Ended 12/31/06

The following amounts were paid to our non-management directors who served
during 2006. Dr. Durham and Mr. McKinnies do not receive any additional
compensation for their service on the Board of Directors.

             Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our officers and
directors and persons who beneficially own more than ten percent of a registered
class of our equity securities to file reports of ownership with the SEC.
Officers, directors and greater than ten percent shareholders are required by
SEC regulation to furnish us with copies of all Section 16(a) forms they file.

Based solely on our review of the copies of such forms received by us, or

                              STOCK INCENTIVE PLANS

During 2003, we adopted the ADA-ES, Inc. 2003 Stock Option Plan (the "2003
Plan"). The plan is intended to encourage our key employees, through their
individual efforts, to improve our overall performance and to promote
profitability by providing these key employees with an opportunity to
participate in the increased value they help create. The 2003 Plan is also
intended to replace the options previously awarded by Earth Sciences, Inc.,
which has been cancelled. Options granted under the 2003 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 2003 Plan is administered by our Board's Compensation Committee.
The plan was approved by Earth Sciences, Inc. as our sole shareholder prior to
the spin-off distribution of our shares. We reserved 400,000 shares of our
common stock for issuance under the 2003 Plan. In general, all options granted
under the 2003 Plan will lapse ten years from the date of grant. In general, the
exercise price of an option will be determined by the Compensation Committee 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, which is typically 25% every six months with total vesting over two
years. Under the 2003 Plan, the grant of options is limited to 20,000 per
individual. During 2005 and 2006, 61,900 and 19,900, respectively, options were
granted under the 2003 Plan. A total of 140,706 options remain available for
future grants under the 2003 Plan. These available options will be cancelled if
Proposal #2 is approved by the shareholders.

During 2004, we adopted the 2004 ESO Plan, which did not require shareholder
approval. The 2004 ESO Plan authorized the grant of up to 200,000 options to
purchase shares of our common stock to our executive officers. The 2004 ESO Plan
is intended to promote our growth and profitability by awarding options to
purchase our common stock in exchange for services performed and to be performed
in the future. Options granted under the 2004 ESO Plan are generally intended to
be non-qualified stock options ("NQSO") for federal income tax purposes. The
2004 ESO Plan is administered by our Board's Compensation Committee. In general,
the exercise price of an option will be determined by the Compensation Committee
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.
Under the 2004 ESO Plan, the grant of options is limited to 60,000 per
individual. The options are exercisable over a 10-year period based on a vesting
schedule, typically between 5% and 20% per year, which may be accelerated based
on performance of the individual recipients as determined by our Board's
Compensation Committee. During 2004, all 200,000 options were granted under the
2004 ESO Plan to five executive officers, each of whom is a full-time employee.
In January 2005 and 2006 and in February 2007, our Board's Compensation
Committee authorized the accelerated vesting of 27,080 options, 38,428 options,
and 17,258 options, respectively, under the 2004 ESO Plan based on performance
metrics in the EC Plan that were met.

During 2004, we adopted the 2004 Stock Compensation Plan #2 (the "2004 Plan")
for the issuance of shares and the grant of options to purchase shares of our
common stock to our non-management directors. The 2004 Plan was approved by our
shareholders at our 2005 Annual Meeting. The 2004 Plan is intended to compensate
our non-management directors by awarding shares and options to purchase shares
for services they rendered during 2004 and 2005 and will continue to render in
subsequent years. The 2004 Plan provided for the award of 603 shares of our
common stock per individual non-management director (4,221 shares in total), and
the grant of 5,000 options per individual non-management director (35,000 in
total), all of which were formally granted and issued in 2005 after approval of
the 2004 Plan by our shareholders. The stock awards and vested portion of the
stock option grants to non-management directors represent a portion of
compensation for services performed from October 2004 through September 2005.
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 of Directors. If such
service is terminated, the non-vested portion of the option is forfeited.

During 2005 we adopted the 2005 Directors' Compensation Plan (the "2005 Plan"),
which authorized the issuance of shares of common stock and the grant of options
to purchase shares of our common stock to non-management directors. The 2005
Plan was approved by our shareholders at the 2005 Annual Meeting. The 2005 Plan
is intended to advance our interests by providing eligible non-management
directors an opportunity to acquire or increase an equity interest in the
Company, create an increased incentive to expend maximum effort for our growth
and success and encourage such eligible individuals to continue to service the
Company. The 2005 Plan provides a portion of the annual compensation to our
non-management directors in the form of awards of shares of common stock and
vesting of options to purchase common stock for services performed for the
Company. Under the 2005 Plan, the award of stock is limited to 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

                                       25




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 is the market price on the
date of grant, the shares of common stock underlying the option will vest at a
rate of no more than 1,667 shares per annual period per individual, and any
unvested shares of Stock that are outstanding at the date the individual is no
longer a director are forfeited. Shares may be issued and options may be granted
under the 2005 Plan only to non-management directors of the Company or its
subsidiaries.

The 2005 Plan will terminate ten years after the date of its adoption, if not
earlier terminated by our Board of Directors. It may be amended, modified or
terminated at any time if and when it is advisable in the absolute discretion of
the Board, although certain amendments are subject to approval of regulatory
bodies and our shareholders. No such amendment may adversely affect any options
previously granted under the Plan without the consent of the recipient(s). The
2005 Plan is administered by a committee appointed by the Board, which currently
consists of all Board members. In January 2006, the Board of Directors
authorized the issuance of 1,000 shares of common stock to each of the seven
non-management directors of the Company (a total of 7,000 shares of common
stock) representing a portion of their compensation for the period from October
2005 through September 2006. In August 2006, the Board of Directors granted
options to purchase 5,000 shares each or a total of 15,000 shares of common
stock to the new directors representing a portion of their compensation, which
vest at a rate of 33% per year.

     (1)  Amounts shown represent options and/or shares covered under our 2003
          Plan, our 2004 ESO Plan, our 2004 Plan and our 2005 Plan described
          above.

     (2)  Amounts shown represent options to purchase 50,000 shares granted to
          Arch Coal as further described below, 10-year options to purchase
          30,000 shares granted to a consultant in 2005 at an exercise price of
          $14.60, and 10-year options to purchase a total of 4,625 shares
          granted to two consultants in 2004 at an exercise price of $13.80.

In November 2006, we entered into an independent contractor agreement with an
individual who is serving as the Project Manager for our project to develop a
proposed activated carbon manufacturing facility. Her compensation package
includes a potential award of 1,448 shares of common stock, worth $20,000 in
value as of the close of business on the date of the Board meeting approving
such package. The stock award was earned in February 2007 upon successful
completion of certain milestones established at the time her compensation
package was approved. This was an individual award not made under any formal
plan and not approved by security holders. See "Stock Incentive Plans" above for
additional information.


    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE


                           Related Party Transactions

In July 2003, we executed the Investment Agreement with Arch Coal. Pursuant to
such agreement, in September 2003 Arch Coal purchased a $300,000 convertible
debenture from us, purchased 137,741 shares of our common stock and was granted
a five-year option to purchase 50,000 additional shares of our common stock for
$10.00 per share. We also granted Arch Coal certain "piggyback" rights in the
event we register certain other equity securities and certain demand
registration rights as part of the transaction. In October 2004, we registered
168,011 shares for resale by Arch Coal, which shares included 50,000 issuable
upon the exercise of the option described above. Until August 2006, we also
co-marketed Arch Coal's ADA-M product and performed certain testing and research
projects under agreements with Arch Coal. Under these arrangements, we recorded
revenue of $261,000 in 2006. A designee of Arch Coal has been appointed a seat
on our Board of Directors and our management 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 Coal holds
at least 100,000 shares of our common stock. Mr. Eaves is Arch Coal's current
designee to our Board of Directors.

                Review and Approval of Related Party Transactions

Our Board of Directors recognizes that related party transactions present a
heightened risk of conflicts of interest and/or improper valuation (or the
perception thereof) and therefore has adopted a policy with respect to all
related party transactions involving the Company. Under this policy, any related
party transaction, as defined and which excludes transactions available to all
employees generally and transactions involving less than $5,000, may be
consummated or may continue only if:

     1.   the Audit Committee has approved or ratified such transaction in
          accordance with the guidelines set forth in the policy and if the
          transaction is on terms comparable to those that could be obtained in
          arm's length dealings with an unrelated third party;

     2.   the transaction has been approved by the disinterested members of the
          Board of Directors; and

     3.   the compensation with respect to such transaction has been approved by
          our Compensation Committee.

Management must recommend any related party transactions it proposes that the
Company enter into to the Audit Committee at its first regularly scheduled
meeting each year. After review, the Audit Committee will approve or disapprove
such transactions and at each subsequently scheduled meeting, management must
update the Audit Committee as to any material change to those proposed
transactions. If management recommends any additional related party transactions
subsequent to such meeting, such transactions may be presented to the Audit
Committee for approval or preliminarily entered into by management subject to
ratification by such Committee. If the Audit Committee does not ratify the
transaction, however, management must make all reasonable efforts to cancel or
annul such transaction.

Any material related party transaction must be disclosed to our full Board of
Directors, and management must assure that all related party transactions are
approved in accordance with any requirements of our financing or other
agreements.

           RELATIONSHIP WITH INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Hein & Associates, LLP has been the independent accounting firm that audits the
financial statements of ADA-ES, Inc. and its subsidiaries since 1989. In
accordance with standing policy, Hein & Associates, LLP periodically changes the
personnel who work on the audit.

The Audit Committee of the Board has not yet selected the independent auditors
for work to be performed during the calendar year ending December 31, 2007. We
intend to engage auditors for the audit of the financial statements for the year
ending December 31, 2007 no later than the second quarter of 2007. We anticipate
that a representative of Hein & Associates, LLP, who conducted the audit for the
year ended December 31, 2006, and a representative of our new auditors, if any
are selected by then, will be present at the Annual Meeting of Shareholders.
There have been no disagreements on matters of accounting principles or
practices, financial statement disclosures or audit scope or procedures between
the Company and Hein & Associates, LLP during the two most recent fiscal years
or any subsequent interim periods. The representative of Hein & Associates, LLP
will be available to respond to shareholder questions and will have the
opportunity to make a statement at that time if the representative desires to do
so.

                                   AUDIT FEES
In addition to performing the audit of the Company's annual consolidated
financial statements, Hein & Associates, LLP provided other services during 2005
and 2006. The aggregate fees billed in 2005 and 2006 for each of the following

                      AUDIT COMMITTEE APPROVAL OF SERVICES

The Audit Committee pre-approves all audit or non-audit services performed by
its principal accountant in accordance with Audit Committee policy and
applicable law. The Audit Committee generally provides pre-approval of audit
services and services associated with SEC registration statements, other SEC
filings and responses to SEC comment letters (Audit Fees) and services related
to internal control reviews, internal control reporting requirements and
consultations with our management as to accounting or disclosure treatment of
transactions or events and the impact of rules, standards or interpretations by
the SEC and other regulatory or standard-setting bodies (Audit-Related Fees) for
each 12-month period within a range of approved fees. To avoid certain potential
conflicts of interest, the law prohibits us from obtaining certain non-audit
services from our independent accountant. The Audit Committee has delegated
authority to approve permissible services to its Chairman. The Chairman reports
such pre-approvals to the full Audit Committee at its next scheduled meeting.
The Audit Committee pre-approved 100% of the services provided by the
independent accountant in 2006. None of the services of the independent
accountant in 2006 were of the type specified in Rule 2-01(c)(7)(i)(C) of
Regulation S-X.

             PROPOSALS OF SHAREHOLDERS FOR PRESENTATION AT THE NEXT
                         ANNUAL MEETING OF SHAREHOLDERS

We anticipate that our next Annual Meeting of Shareholders will be held in May
2008. Any Shareholder of record of the Company who desires to submit a proper
proposal for inclusion in the proxy material related to the next Annual Meeting
of Shareholders must do so in writing and it must be received at our principal
executive offices on or before January 5, 2008. If a shareholder intends to
submit a proposal at the meeting that is not included in the Company's proxy
statement, and the shareholder fails to notify the Company prior to March 23,
2008 of such proposal, then the proxies appointed by the Company's management
would be allowed to use their discretionary voting authority when the proposal
is raised at the annual meeting, without any discussion of the matter in the
proxy statement. The proponent must own 1% or more of the outstanding shares or
$2,000 in market value, of the Company's Common Stock and must have continuously
owned such shares for one year and intend to continue to hold such shares
through the date of the Annual Meeting in order to present a shareholder
proposal to the Company.

                           ANNUAL REPORT ON FORM 10-K

We will provide our Annual Report on Form 10-K concerning our operations during
the calendar year ended December 31, 2006, including certified consolidated
financial statements and any financial statement schedules for the year then
ended, to our shareholders without charge upon request to Mark H. McKinnies,
Secretary, ADA-ES, Inc., 8100 SouthPark Way, Unit B, Littleton, Colorado 80120.
Exhibits listed in the Form 10-K are available upon request to shareholders at a
nominal charge for printing and mailing.


                           INCORPORATION BY REFERENCE

We hereby incorporate by reference Items 6, 7, 8, and 9 of Part II of our Form
10-K for the fiscal year ended December 31, 2006.


                                  OTHER MATTERS

The Board knows of no other business to be presented at the Annual Meeting of
Shareholders. If other matters properly come before the Meeting, the persons
named in the accompanying form of Proxy intend to vote on such other matters in
accordance with their best judgment.

4. Administration of the Plan. (a) Plan Administrator.

                (i) Administration with Respect to Directors and Officers. With
respect to grants of Awards to Directors or Employees who are also Officers or
Directors of the Company, the Plan shall be administered by (A) the Board or (B)

such a manner as to satisfy the Applicable Laws and to permit such grants and
related transactions under the Plan to be exempt from Section 16(b) of the

continue to serve in its designated capacity until otherwise directed by the
Board.

                (ii) Administration With Respect to Consultants and Other
Employees. With respect to grants of Awards to Employees or Consultants who are
neither Directors nor Officers of the Company, the Plan shall be administered by
(A) the Board or (B) a Committee designated by the Board, which Committee shall
be constituted in such a manner as to satisfy the Applicable Laws. Once
appointed, such Committee shall continue to serve in its designated capacity
until otherwise directed by the Board.

                (iii) Administration With Respect to Covered Employees.
Notwithstanding the foregoing, as of and after the date that the exemption for
the Plan under Section 162(m) of the Code expires, as set forth in Section 18
below, grants of Awards to any Covered Employee intended to qualify as
Performance-Based Compensation shall be made only by a Committee (or
subcommittee of a Committee) which is comprised solely of two or more Directors
eligible to serve on a committee making Awards qualifying as Performance-Based
Compensation. In the case of such Awards granted to Covered Employees,
references to the "Administrator" or to a "Committee" shall be deemed to be
references to such Committee or subcommittee.

                                      -7-




           (b) Multiple Administrative Bodies. The Plan may be administered by
different bodies with respect to Directors, Officers, Consultants and Employees
who are neither Directors nor Officers.

           (c) Powers of the Administrator. Subject to Applicable Laws and the
provisions of the Plan (including any other powers given to the Administrator
hereunder), and except as otherwise provided by the Board, the Administrator
shall have the authority, in its discretion:

                (i) to select the Employees, Directors and Consultants to whom
Awards may be granted from time to time hereunder;

                (ii) to determine whether and to what extent Awards are granted
hereunder;

                (iii) to determine the number of Shares or the amount of other
consideration to be covered by each Award granted hereunder;

                (iv) to approve forms of Award Agreements for use under the
Plan;

                (v) to determine the terms and conditions of any Award granted
hereunder;

                (vi) to establish additional terms, conditions, rules or
procedures to accommodate the rules or laws of applicable foreign jurisdictions
and to afford Grantees favorable treatment under such rules or laws; provided,
however, that no Award shall be granted under any such additional terms,
conditions, rules or procedures with terms or conditions which are inconsistent
with the provisions of the Plan;

                (vii) to amend the terms of any outstanding Award granted under
the Plan, provided that any amendment that would adversely affect the Grantee's
rights under an outstanding Award shall not be made without the Grantee's
written consent;

                (viii) to construe and interpret the terms of the Plan and
Awards, including without limitation, any notice of award or Award Agreement,
granted pursuant to the Plan; and

                (ix) to take such other action, not inconsistent with the terms
of the Plan, as the Administrator deems appropriate.

     5. Eligibility. Awards other than Incentive Stock Options may be granted to
Employees, Directors and Consultants. Incentive Stock Options may be granted
only to Employees of the Company or a Parent or a Subsidiary of the Company. An
Employee, Director or Consultant who has been granted an Award may, if otherwise
eligible, be granted additional Awards. Awards may be granted to such Employees,
Directors or Consultants who are residing in foreign jurisdictions as the
Administrator may determine from time to time.

                                      -8-




     6. Terms and Conditions of Awards. (a) Designation of Award. Each Award
shall be designated in the Award Agreement. In the case of an Option, the Option
shall be designated as either an Incentive Stock Option or a Non-Qualified Stock
Option. However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of Shares subject to Options designated as Incentive
Stock Options which become exercisable for the first time by a Grantee during
any calendar year (under all plans of the Company or any Parent or Subsidiary of
the Company) exceeds $100,000, such excess Options, to the extent of the Shares
covered thereby in excess of the foregoing limitation, shall be treated as
Non-Qualified Stock Options. For this purpose, Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the grant date of the relevant
Option.

           (b) Conditions of Award. Subject to the terms of the Plan, the
Administrator shall determine the provisions, terms and conditions of each Award
including, but not limited to, the Award vesting schedule, repurchase
provisions, rights of first refusal, forfeiture provisions, form of payment
(cash, Shares, or other consideration) upon settlement of the Award, payment
contingencies and satisfaction of any performance criteria. The performance
criteria established by the Administrator may be based on any one of, or
combination of, increase in share price, earnings per share, total stockholder
return, return on equity, return on assets, return on investment, net operating
income, cash flow, revenue, economic value added, personal management objectives
or other measure of performance selected by the Administrator. Partial
achievement of the specified criteria may result in a payment or vesting
corresponding to the degree of achievement as specified in the Award Agreement.

           (c) Acquisitions and Other Transactions. The Administrator may issue
Awards under the Plan in settlement, assumption or substitution for outstanding
awards or obligations to grant future awards in connection with the Company or a
Related Entity acquiring another entity, an interest in another entity or an
additional interest in a Related Entity whether by merger, stock purchase, asset
purchase or other form of transaction.

           (d) Deferral of Award Payment. The Administrator may establish one or
more programs under the Plan to permit selected Grantees the opportunity to
elect to defer receipt of consideration upon exercise of an Award, satisfaction
of performance criteria or other event that absent the election would entitle
the Grantee to payment or receipt of Shares or other consideration under an
Award (but only to the extent that such deferral programs would not result in an
accounting compensation charge unless otherwise determined and specifically
agreed to by the Administrator). The Administrator may establish the election
procedures, the timing of such elections, the mechanisms for payments of and
accrual of interest or other earnings, if any, on amounts, Shares or other
consideration so deferred and such other terms, conditions, rules and procedures
that the Administrator deems advisable for the administration of any such
deferral program. Irrespective of the rights of the Administrator to allow for
the deferral of consideration hereunder, no such deferral shall be effective if
it would result in the deferral constituting "nonqualified deferred
compensation" within the meaning of Code Section 409A, unless such deferral has
been approved by the Board and agreed to by the Grantee.

                                       -9-




           (e) Separate Programs. The Administrator may establish one or more
separate programs under the Plan for the purpose of issuing particular forms of
Awards to one or more classes of Grantees on such terms and conditions as
determined by the Administrator from time to time.

           (f) Individual Award Limits. Following the date that the exemption
from application of Section 162(m) of the Code described in Section 18 (or any
exemption having similar effect) ceases to apply to Awards, the maximum number
of Shares with respect to which Awards (including awards for Options or
Restricted Stock) may be granted to any Grantee in any fiscal year of the
Company shall be thirty thousand (30,000) Shares; provided, however, that
Non-Management Directors shall be entitled to receive Awards in any fiscal year
for no more than ten thousand (10,000) Shares. In connection with a Grantee's
commencement of Continuous Service, a Grantee who is an Employee may be granted
Options for up to an additional thirty thousand (30,000) Shares which shall not
count against the limit set forth in the previous sentence. The foregoing
limitations shall be adjusted proportionately in connection with any change in
the Company's capitalization pursuant to Section 10 below. To the extent
required by Section 162(m) of the Code or the regulations thereunder, in
applying the foregoing limitations with respect to a Grantee, if any Option is
canceled, the canceled Option shall continue to count against the maximum number
of Shares with respect to which Options may be granted to the Grantee. For this
purpose, the repricing of an Option shall be treated as the cancellation of the
existing Option and the grant of a new Option.

           (g) Early Exercise. The Award Agreement may, but need not, include a
provision whereby the Grantee may elect at any time while an Employee, Director
or Consultant to exercise any part or all of the Award prior to full vesting of
the Award. Any unvested Shares received pursuant to such exercise may be subject
to a repurchase right in favor of the Company or a Related Entity or to any
other restriction the Administrator determines to be appropriate.

           (h) Term of Award. The term of each Award shall be the term stated in
the Award Agreement, provided, however, that the term of an Incentive Stock
Option may not be more than ten (10) years from the date of grant thereof.
However, in the case of an Incentive Stock Option granted to a Grantee who, at
the time the Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary of the Company, the term of the Incentive Stock Option shall be
five (5) years from the date of grant thereof or such shorter term as may be
provided in the Award Agreement.

           (i) Transferability of Awards. Incentive Stock Options and other
Awards may not be sold, pledged, assigned, hypothecated, transferred or disposed
of in any manner other than by will or by the laws of descent or distribution
and may be exercised, during the lifetime of the Grantee, only by the Grantee.
Non-Qualified Stock Options shall be transferable by will, by the laws of
descent and distribution or to the extent and in the manner authorized by the
Administrator, by gift to members of the Grantee's Immediate Family.

           (j) Time of Granting Awards. The date of grant of an Award shall for
all purposes be the date on which the Administrator makes the determination to
grant such Award or such other date as is determined by the Administrator.

                                      -10-




     7. Award Exercise or Purchase Price, Consideration and Taxes. (a) Exercise
or Purchase Price. The exercise or purchase price, if any, for an Award shall be
as follows:

                (i) In the case of an Incentive Stock Option:

                    (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or
Subsidiary of the Company, the per Share exercise price shall be not less than
one hundred ten percent (110%) of the Fair Market Value per Share on the date of
grant; or

                    (B) granted to any Employee other than an Employee described
in the preceding paragraph, the per Share exercise price shall be not less than
one hundred percent (100%) of the Fair Market Value per Share on the date of
grant.

                (ii) In the case of a Non-Qualified Stock Option, the per Share
exercise price shall be not less than eighty-five percent (85%) of the Fair
Market Value per Share on the date of grant, unless otherwise determined by the
Administrator.

                (iii) In the case of Awards intended to qualify as
Performance-Based Compensation, the exercise or purchase price, if any, shall be
not less than one hundred percent (100%) of the Fair Market Value per Share on
the date of grant.

                (iv) Notwithstanding the foregoing provisions of this Section
7(a), in the case of an Award issued pursuant to Section 6(c), above, the
exercise or purchase price for the Award shall be determined in accordance with
the provisions of the relevant instrument evidencing the agreement to issue such
Award.

           (b) Attribution Rule. For purposes of subsection 7(a)(i)(A) above, in
determining stock ownership, an employee shall be deemed to own the stock owned,
directly or indirectly, by his or her Immediate Family. Stock owned, directly or
indirectly, by or for a corporation, partnership, estate or trust shall be
deemed to be owned proportionately by or for its stockholders, partners or
beneficiaries. If an employee or a person related to the employee owns an
unexercised option or warrant to purchase stock of the Company, the stock
subject to that portion of the option or warrant which is unexercised shall not
be counted in determining stock ownership. For purposes of this Section 7, stock
owned by an employee shall include all stock owned by him or her which is
actually issued and outstanding immediately before the grant of the incentive
stock option to the employee.

           (c) Consideration. Subject to Applicable Laws, the consideration to
be paid for the Shares to be issued upon exercise or purchase of an Award,
including the method of payment, shall be determined by the Administrator (and,
in the case of an Incentive Stock Option, shall be determined at the time of
grant). In addition to any other types of consideration the Administrator may
determine, the Administrator is authorized to accept as consideration for Shares
issued under the Plan the following:

                                      -11-




                (i) cash;

                (ii) check;

                (iii) delivery of Grantee's promissory note with such recourse,
interest, security and redemption provisions as the Administrator determines as
appropriate (but only to the extent that the acceptance or terms of the
promissory note would not violate an Applicable Law and would not result in an
accounting compensation charge with respect to the use of such promissory note
to pay the exercise price unless otherwise determined by the Administrator);
provided, however, that no less than the greater of an amount equal to the "par
value" of the Common Stock to be issued upon the exercise of an Award (if such
stock has a "par value") or $.01 per share shall be paid in cash or other
property having a value no less than the par value of such shares or $.01 per
share, as applicable, and may not be included in the amount of any deferred
obligation;

                (iv) surrender of Shares or delivery of a properly executed form
of attestation of ownership of Shares as the Administrator may require which
have a Fair Market Value on the date of surrender or attestation equal to the
aggregate exercise price of the Shares as to which said Award shall be exercised
(but only to the extent that such exercise of the Award would not result in an
accounting compensation charge with respect to the Shares used to pay the
exercise price unless otherwise determined by the Administrator; generally an
accounting charge will result if the Shares used to pay the exercise price were
acquired less than six months before the exercise);

                (v) with respect to Options, payment through a broker-dealer
sale and remittance procedure pursuant to which the Grantee (A) provides written
instructions to a Company designated brokerage firm to effect the immediate sale
of some or all of the purchased Shares and remit to the Company sufficient funds
to cover the aggregate exercise price payable for the purchased Shares and (B)
provides written directives to the Company to deliver the certificates for the
purchased Shares directly to such brokerage firm in order to complete the sale
transaction; or

                (vi) any combination of the foregoing methods of payment.

           (d) Taxes. No Shares shall be delivered under the Plan to any Grantee
or other person until such Grantee or other person has made arrangements
acceptable to the Administrator for the satisfaction of any foreign, federal,
state or local income and employment tax withholding obligations, including,
without limitation, obligations incident to the receipt of Shares or the
disqualifying disposition of Shares received on exercise of an Incentive Stock
Option. Upon exercise of an Award, the Company shall withhold or collect from
Grantee an amount sufficient to satisfy such tax obligations.

     8. Procedure for Exercise; Rights as a Stockholder. (a) Any Award granted
hereunder shall be exercisable at such times and under such conditions as
determined by the Administrator under the terms of the Plan and specified in the
Award Agreement.

                                      -12-




           (b) An Award shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Award by the person entitled to exercise the Award and full payment for the
Shares with respect to which the Award is exercised has been made, including, to
the extent selected, use of the broker-dealer sale and remittance procedure to
pay the purchase price as provided in Section 7(c)(v). Until the issuance (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing
such Shares, no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to Shares subject to an Award,
notwithstanding the exercise of an Option or other Award. No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in the Award Agreement
or Section 10 below.

     9. Conditions Upon Issuance of Shares. (a) Shares shall not be issued
pursuant to the exercise of an Award unless the exercise of such Award and the
issuance and delivery of such Shares pursuant thereto comply with all Applicable
Laws. Compliance with all Applicable Laws shall be determined by counsel for the
Company.

           (b) As a condition to the exercise of an Award, the Company may
require the person exercising such Award to represent and warrant at the time of
any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any
Applicable Laws. THE COMPANY SHALL NOT BE OBLIGATED, BY REASON OF THIS PROVISION
OR OTHERWISE, TO UNDERTAKE REGISTRATION OF THE OPTIONS OR STOCK HEREUNDER.

     10. Adjustments Upon Changes in Capitalization. Subject to any required
action by the stockholders of the Company, the number of Shares covered by each
outstanding Award, the number of Shares which have been authorized for issuance
under the Plan but as to which no Awards have yet been granted or which have
been returned to the Plan, the exercise or purchase price of each such
outstanding Award, the maximum number of Shares with respect to which Options
may be granted to any Grantee in any fiscal year of the Company as well as any
other terms that the Administrator determines require adjustment shall be
proportionately adjusted for (i) any increase or decrease in the number of
issued Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Shares or similar transaction affecting
the Shares, (ii) any other increase or decrease in the number of issued Shares
effected without receipt of consideration by the Company and (iii) as the
Administrator may determine in its discretion, any other transaction with
respect to Common Stock including a corporate merger, consolidation, acquisition
of property or stock, separation (including a spin-off or other distribution of
stock or property), reorganization, liquidation (whether partial or complete) or
any similar transaction; provided, however that conversion of any convertible
securities of the Company shall not be deemed to have been "effected without
receipt of consideration." Such adjustment shall be made by the Administrator,
and its determination shall be final, binding and conclusive. Except as the
Administrator determines, no issuance by the Company of shares of stock of any

                                      -13-




class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason hereof shall be made with respect to, the
number or price of Shares subject to an Award.

     11. Corporate Transactions and Changes in Control. (a) Termination of Award
to Extent Not Assumed in Corporate Transaction. Effective upon the consummation
of a Corporate Transaction, all outstanding Awards under the Plan shall
terminate. However, all such Awards shall not terminate to the extent they are
Assumed in connection with the Corporate Transaction.

           (b) Acceleration of Award Upon Corporate Transaction or Change in
Control.

                (i) Corporate Transaction. Except as provided otherwise in an
individual Award Agreement, in the event of a Corporate Transaction and:

                    (A) for the portion of each Award that is Assumed or
Replaced, then such Award (if Assumed), the replacement Award (if Replaced) or
the cash incentive program (if Replaced) automatically shall become fully
vested, exercisable and payable and be released from any repurchase or
forfeiture rights (other than repurchase rights exercisable at Fair Market
Value) for all of the Shares at the time represented by such Assumed or Replaced
portion of the Award, immediately upon termination of the Grantee's Continuous
Service if such Continuous Service is terminated by the successor company or the
Company without Cause or voluntarily by the Grantee with Good Reason within
twelve (12) months after the Corporate Transaction; and

                    (B) for the portion of each Award that is neither Assumed
nor Replaced, such portion of the Award shall automatically become fully vested
and exercisable and be released from any repurchase or forfeiture rights (other
than repurchase rights exercisable at Fair Market Value) for all of the Shares
at the time represented by such portion of the Award, immediately prior to the
specified effective date of such Corporate Transaction.

                (ii) Change in Control. Except as provided otherwise in an
individual Award Agreement, following a Change in Control (other than a Change
in Control which also is a Corporate Transaction) and upon the termination of
the Continuous Service of a Grantee if such Continuous Service is terminated by
the Company or Related Entity without Cause or voluntarily by the Grantee with
Good Reason within twelve (12) months after a Change in Control, each Award of
such Grantee which is at the time outstanding under the Plan automatically shall
become fully vested and exercisable and be released from any repurchase or
forfeiture rights (other than repurchase rights exercisable at Fair Market
Value), immediately upon the termination of such Continuous Service.

           (c) Effect of Acceleration on Incentive Stock Options. Any Incentive
Stock Option accelerated under this Section 11 in connection with a Corporate
Transaction or Change in Control shall remain exercisable as an Incentive Stock
Option under the Code only to the extent the $100,000 dollar limitation of
Section 422(d) of the Code is not exceeded. To the extent such dollar limitation
is exceeded, a proportional fraction of each share subject to such Option will
be allocated as part Incentive Stock Option and part Non-Qualified Stock Option.

                                      -14-




     12. Effective Date and Term of Plan. The Plan shall become effective upon
the earlier to occur of its adoption by the Board or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated. Subject to Section 17 below, and Applicable
Laws, Awards may be granted under the Plan upon its becoming effective.

     13. Amendment, Suspension or Termination of the Plan; Code Section 409A
Considerations.

           (a) The Board may at any time amend, suspend or terminate the Plan.
To the extent necessary to comply with Applicable Laws, the Company shall obtain
stockholder approval of any Plan amendment in such a manner and to such a degree
as required.

           (b) No Award may be granted during any suspension of the Plan or
after termination of the Plan.

           (c) No suspension or termination of the Plan (including termination
of the Plan under Section 12, above) shall adversely affect any rights under
Awards already granted to a Grantee.

           (d) Any amendment of the Plan may be accomplished in a manner
calculated to cause such amendment not to constitute an "extension," "renewal"
or "modification" (each within the meaning of Code Section 409A) of any Awards
that would cause such Awards to be considered "nonqualified deferred
compensation" (within the meaning of Code Section 409A). Notwithstanding the
foregoing, if at any time the Board or the Administrator determines that any
Award may be subject to Code Section 409A, the Board or the Administrator may,
in its sole discretion, and without a Grantee's prior consent, amend the Plan or
any Award as it may determine is necessary or desirable either for the Plan and
Awards to be exempt from the application of Section 409A or to satisfy the
requirements of Section 409A, including by adding conditions with respect to the
vesting and/or the payment of Awards.

     14. Reservation of Shares. (a) The Company, during the term of the Plan,
will at all times reserve and keep available such number of Shares as are
sufficient to satisfy the requirements of the Plan.

           (b) The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority is not obtained.

     15. No Effect on Terms of Employment/Consulting Relationship. The Plan
shall not confer upon any Grantee any right with respect to the Grantee's
Continuous Service and shall not interfere in any way with his or her right or

                                      -15-




the right of the Company or any Related Entity to terminate the Grantee's
Continuous Service at any time, with or without Cause and with or without
notice. The ability of the Company or any Related Entity to terminate the
employment of a Grantee who is employed at will is in no way affected by its
determination that the Grantee's Continuous Service has been terminated for
Cause for the purposes of this Plan.

     16. No Effect on Retirement and Other Benefit Plans. Except as specifically
provided in a retirement or other benefit plan of the Company or a Related
Entity, Awards shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Company or a Related
Entity, and shall not affect any benefits under any other benefit plan of any
kind or any benefit plan subsequently instituted under which the availability or
amount of benefits is related to level of compensation. The Plan is not a
"Retirement Plan" or "Welfare Plan" under the Employee Retirement Income
Security Act of 1974, as amended.

     17. Stockholder Approval. The grant of Incentive Stock Options under the
Plan, excluding Incentive Stock Options issued in substitution for outstanding
Incentive Stock Options pursuant to Section 424(a) of the Code, shall be subject
to approval of the Plan by the stockholders of the Company within twelve (12)
months before or after the date the Plan is adopted. Such stockholder approval
shall be obtained in the degree and manner required under Applicable Laws. The
Administrator may grant Incentive Stock Options under the Plan prior to approval
by the stockholders, but until such approval is obtained, no such Incentive
Stock Option shall be exercisable. If stockholder approval is not obtained
within the twelve (12) month period provided above, all Incentive Stock Options
previously granted under the Plan shall be exercisable as Non-Qualified Stock
Options.

     18. Effect of Section 162(m) of the Code. At any time while the Company is
subject to the reporting obligations of Section 12 of the Exchange Act, the Plan
and all Awards (except Awards of Restricted Stock that vest over time) issued
thereunder are intended to be exempt from the application of Section 162(m) of
the Code, which restricts under certain circumstances the Federal income tax
deduction for compensation paid by a public company to named executives in
excess of $1 million per year. The exemption is based on Treasury Regulation
Section 1.162-27(f), in the form existing on the effective date of the Plan,
with the understanding that such regulation generally exempts from the
application of Section 162(m) of the Code compensation paid pursuant to a plan
that existed before a company becomes publicly held. Under such Treasury
Regulation, this exemption is available to the Plan for the duration of the
period that lasts until the earliest of (i) the expiration of the Plan, (ii) the
material modification of the Plan, (iii) the exhaustion of the maximum number of
shares of Common Stock available for Awards under the Plan, as set forth in
Section 3(a), (iv) the first meeting of stockholders at which directors are to
be elected that occurs after the close of the third calendar year following the
calendar year in which the Company first becomes subject to the reporting
obligations of Section 12 of the Exchange Act, or (v) such other date required
by Section 162(m) of the Code and the rules and regulations promulgated
thereunder. To the extent that the Administrator determines as of the date of
grant of an Award that (i) the Award is intended to qualify as Performance-Based
Compensation and (ii) the exemption described above is no longer available with
respect to such Award, such Award shall not be effective until any stockholder
approval required under Section 162(m) of the Code has been obtained.

                                      -16-




     19. Code Section 409A Matters. Except as may be expressly provided with
respect to any Award granted under the Plan, the Plan and the Awards are not
intended to constitute a "nonqualified deferred compensation plan" within the
meaning of Code Section 409A, but rather are intended to be exempt from the
application of Code Section 409A. To the extent that the Plan and/or Awards are
nevertheless deemed to be subject to Code Section 409A, the Plan and Awards
shall be interpreted in accordance with Code Section 409A and any applicable
Department of Treasury regulations and other interpretive guidance issued
thereunder, including without limitation any such regulations or other guidance
that may be issued after the grant of any Award. Notwithstanding any provision
of the Plan or any Award to the contrary, in the event that the Administrator
determines that any Award may be or become subject to Code Section 409A, the
Administrator may adopt such amendments to the Plan and the affected Award (as
described above) or adopt other policies and procedures (including amendments,
policies and procedures with retroactive effect), or take any other actions,
that the Administrator determines are necessary or appropriate (a) to exempt the
Plan and any Award from the application of Code Section 409A and/or preserve the
intended tax treatment of the benefits provided with respect to the Award, or
(b) to comply with the requirements of Code Section 409A.

     20. Qualified Domestic Relations Orders. (a) Anything in the Plan to the
contrary notwithstanding, rights under Awards may be assigned to an Alternate
Payee to the extent that a QDRO so provides. (The terms "Alternate Payee" and
"QDRO" are defined in paragraph 20(c) below.) The assignment of an Award to an
Alternate Payee pursuant to a QDRO shall not be treated as having caused a new
grant. The transfer of an Incentive Stock Option to an Alternate Payee may,
however, cause it to fail to qualify as an Incentive Stock Option. If an Award
is assigned to an Alternate Payee, the Alternate Payee generally shall have the
same rights as the grantee under the terms of the Plan; provided however, that
(i) the Award shall be subject to the same vesting terms and exercise period as
if the Award were still held by the grantee and (ii) an Alternate Payee may not
transfer an Award.

           (b) In the event of the Administrator's receipt of a domestic
relations order or other notice of adverse claim by an Alternate Payee of a
grantee of an Award, transfer of the proceeds of the exercise of such Award,
whether in the form of cash, stock or other property, may be suspended. Such
proceeds shall thereafter be transferred pursuant to the terms of a QDRO or
other agreement between the Grantee and Alternate Payee. A Grantee's ability to
exercise an Award may be barred if the Administrator receives a court order
directing the Plan administrator not to permit exercise.

           (c) The word "QDRO" as used in the Plan shall mean a court order (i)
that creates or recognizes the right of the spouse, former spouse or child (an
"Alternate Payee") of an individual who is granted an Award to an interest in
such Award relating to marital property rights or support obligations and (ii)
that the administrator of the Plan determines would be a "qualified domestic
relations order," as that term is defined in section 414(p) of the Code and
section 206(d) of the Employee Retirement Income Security Act ("ERISA"), but for
the fact that the Plan is not a plan described in section 3(3) of ERISA.

                                      -17-




           21. Section 16(b) Compliance and Bifurcation of Plan. It is the
intention of the Company that this Plan comply in all respects with Section
16(b) and Rule 16b-3 under the Exchange Act, to the extent applicable, and, if
any Plan provision is later found not to be in compliance with such Section or
Rule, as the case may be, the provision shall be deemed null and void, and in
all events the Plan shall be construed in favor of its meeting the requirements
of Section 16(b) and Rule 16b-3 under the Exchange Act. Notwithstanding anything
in the Plan to the contrary, the Board, in its absolute discretion, may
bifurcate the Plan so as to restrict, limit or condition the use of any
provision of the Plan to participants who are officers and directors or other
persons subject to Section 16(b) of the Exchange Act without so restricting,
limiting or conditioning the Plan with respect to other participants.

           The undersigned, being the Secretary of ADA-ES, Inc. hereby certifies
that the foregoing is a true and correct copy of the ADA-ES, Inc. 2007 Equity
Incentive Plan, as adopted by the Board of Directors on ____________________,

Vesting Schedule:
-----------------

     Subject to the Grantee's Continuous Service and other limitations set forth
in this Notice, the Plan and the Option Agreement, the Option may be exercised,
in whole or in part, in accordance with the following schedule:

                  Period of Grantee's
                  Continuous Relationship
                  With the Company or
                  Affiliate From the Date            Portion of Total Option
                  the Option is Granted                Which is Exercisable

                  End of ___ months                            ___%
                  Each month thereafter                        ___%
                  ___ months                                   100%





     During any authorized leave of absence, the vesting of the Option as
provided in this schedule shall be suspended after the leave of absence exceeds
a period of ninety (90) days. Vesting of the Option shall resume upon the
Grantee's termination of the leave of absence and return to service to the
Company or a Related Entity. The Vesting Schedule of the Option shall be
extended by the length of the suspension.

     In the event of termination of the Grantee's Continuous Service for Cause,
the Grantee's right to exercise the Option shall terminate concurrently with the
termination of the Grantee's Continuous Service, except as otherwise determined
by the Administrator.

     In the event of the Grantee's change in status from Employee to Consultant
or from an Employee whose customary employment is 20 hours or more per week to
an Employee whose customary employment is fewer than 20 hours per week, vesting
of the Option shall continue only to the extent determined by the Administrator
as of such change in status.

     IN WITNESS WHEREOF, the Company and the Grantee have executed this Notice
and agree that the Option is to be governed by the terms and conditions of this
Notice, the Plan and the Option Agreement.

                                       ADA-ES, INC., a Colorado corporation

                                       By:
                                           -------------------------------------

                                       Title:
                                              ----------------------------------

The Grantee acknowledges and agrees that the Shares subject to the Option shall
vest, if at all, only during the period of the Grantee's Continuous Service (not
through the act of being hired, being granted the Option or acquiring Shares
hereunder). The Grantee further acknowledges and agrees that nothing in this
Notice, the Option Agreement or the Plan shall confer upon the Grantee any right
with respect to future Awards or continuation of the Grantee's Continuous
Service or interfere in any way with the Grantee's right or the right of the
Company or Related Entity to which the Grantee provides services to terminate
the Grantee's Continuous Service, with or without cause and with or without
notice. The Grantee acknowledges that unless the Grantee has a written
employment agreement with the Company to the contrary, the Grantee's status is
at will.

     The Grantee acknowledges receipt of a copy of the Plan and the Option
Agreement and represents that he or she:

(a) is familiar with the terms and provisions thereof and hereby accepts the
Option, effective as of the date of grant stated above, subject to all of the
terms and provisions hereof and thereof;

(b) has reviewed this Notice, the Plan and the Stock Option Award Option
Agreement being executed and delivered herewith in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Notice and
fully understands all provisions of this Notice, the Plan and the Option Award
Agreement.

     Grantee hereby agrees that all disputes arising out of or relating to this
Notice, the Plan and the Option Agreement shall be resolved in accordance with
Section 18 of the Option Agreement.

     Grantee further agrees to notify the Company upon any change in the
residence address indicated in this Notice.

     Grantee agrees, as a condition precedent to any exercise of the Option, to
deliver to the Company:

(a)  an executed Exercise Notice in the form provided by the Company, which
     notice may include (i) written assurances satisfactory to the Company as to
     Grantee's knowledge and experience in financial and business matters and/or
     that Grantee has employed a purchaser representative who has such knowledge
     and experience in financial and business matters, and that Grantee is
     capable of evaluating, alone or together with a purchaser representative
     engaged by Grantee, the merits and risks of exercising the Option; and (ii)
     written assurances satisfactory to the Company stating that Grantee is
     acquiring the Common Stock subject to the Option for such person's own
     account and not with any present intention of selling or otherwise
     distributing the Common Stock. (These requirements, and any assurances
     given pursuant to such requirements, shall be inoperative if, and only if:
     (x) the issuance of the shares upon the exercise of the Option has been
     registered under a then currently effective registration statement under
     the Securities Act of 1933, as amended (the "Securities Act"); or (y) as to
     any particular requirement, a determination is made by counsel for the
     Company that such requirement need not be met in the circumstances under
     the then applicable securities law.); and

(b)  an executed Shareholders Agreement (if any) in the form existing at the
     time of exercise of the Option (as modified by the Company in its
     discretion);

                                                      Award Number:  ___________

                     ADA-ES INC. 2007 EQUITY INCENTIVE PLAN
                          STOCK OPTION AWARD AGREEMENT

     1. Grant of Option. ADA-ES, Inc., a Colorado corporation (the "Company"),
hereby grants to the Grantee (the "Grantee") named in the Notice of Stock Option
Award (the "Notice"), an option (the "Option") to purchase the Total Number of
Shares of Common Stock subject to the Option (the "Shares") set forth in the
Notice, at the Exercise Price per Share set forth in the Notice (the "Exercise
Price") subject to the terms and provisions of the Notice, this Stock Option
Award Agreement (the "Option Agreement") and the Company's 2007 Equity Incentive
Plan, as amended from time to time (the "Plan"), which are incorporated herein
by reference. Unless otherwise defined herein, the terms defined in the Plan
shall have the same defined meanings in this Option Agreement.

     If designated in the Notice as an Incentive Stock Option, the Option is
intended to qualify as an Incentive Stock Option as defined in Section 422 of
the Code. However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of Shares subject to Options designated as Incentive
Stock Options which become exercisable for the first time by the Grantee during
any calendar year (under all plans of the Company or any Parent or Subsidiary of
the Company) exceeds $100,000, such excess Options, to the extent of the Shares
covered thereby in excess of the foregoing limitation, shall be treated as
Non-Qualified Stock Options. For this purpose, Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the date the Option with respect
to such Shares is awarded.

     If designated in the Notice as a Nonqualified Stock Option, the Option is
NOT intended to qualify as an Incentive Stock Option.

     To the extent any Stock Option is designated as an Incentive Stock Option,
but for any reason (including the reason described above) fails to qualify as an
Incentive Stock Option, such option shall be treated as a Nonqualified Stock
Option.

     2. Exercise of Option. (a) Right to Exercise. The Option shall be
exercisable during its term in accordance with the Vesting Schedule set out in
the Notice and with the applicable provisions of the Plan and this Option
Agreement. The Option shall be subject to the provisions of Section 11 of the
Plan relating to the exercisability or termination of the Option in the event of
a Corporate Transaction or Change in Control. The Grantee shall be subject to
reasonable limitations on the number of requested exercises during any monthly
or weekly period as determined by the Administrator. In no event shall the
Company issue fractional Shares.

        (b) Method of Exercise. The Option shall be exercisable by delivery of
an exercise notice (a form of which is attached hereto as Exhibit A) or by such
other procedure as specified from time to time by the Administrator which shall




state the election to exercise the Option, the whole number of Shares in respect
of which the Option is being exercised and such other provisions as may be
required by the Administrator. The exercise notice shall be delivered in person,
by certified mail or by such other method (including electronic transmission) as
determined from time to time by the Administrator to the Company accompanied by
payment of the Exercise Price. The Option shall be deemed to be exercised upon
receipt by the Company of such notice accompanied by the Exercise Price, which,
to the extent selected, shall be deemed to be satisfied by use of the
broker-dealer sale and remittance procedure to pay the Exercise Price provided
in Section 4(d) below.

        (c) Shareholders Agreement. As a condition precedent to any exercise of
the Option, the Grantee shall deliver to the Company at the time of exercise, an
executed Shareholders Agreement in the form existing at the time of exercise of
the Option (as modified by the Company in its discretion as of such time).

        (d) Taxes. No Shares will be delivered to the Grantee or other person
pursuant to the exercise of the Option until the Grantee or other person has
made arrangements acceptable to the Administrator for the satisfaction of
applicable income tax and employment tax withholding obligations, including,
without limitation, such other tax obligations of the Grantee incident to the
receipt of Shares or the disqualifying disposition of Shares received on
exercise of an Incentive Stock Option. Upon exercise of the Option, the Company
or the Grantee's employer may offset or withhold (from any amount owed by the
Company or the Grantee's employer to the Grantee) or collect from the Grantee or
other person an amount sufficient to satisfy such tax obligations and/or the
employer's withholding obligations.

     3. Grantee's Representations. The Grantee understands that neither the
Option nor the Shares exercisable pursuant to the Option have been registered
under the Securities Act of 1933, as amended or any United States securities
laws. If the Shares purchasable pursuant to the exercise of the Option have not
been registered under the Securities Act of 1933, as amended, at the time the
Option is exercised, the Grantee shall, if requested by the Company,
concurrently with the exercise of all or any portion of the Option, deliver to
the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B.

     4. Method of Payment. Payment of the Exercise Price shall be made by any of
the following, or a combination thereof, at the election of the Grantee;
provided, however, that such exercise method does not then violate any
Applicable Law:

        (a) cash;

        (b) check;

        (c) surrender of Shares or delivery of a properly executed form of
attestation of ownership of Shares as the Administrator may require (including
withholding of Shares otherwise deliverable upon exercise of the Option) which
have a Fair Market Value on the date of surrender or attestation equal to the
aggregate Exercise Price of the Shares as to which the Option is being exercised
(but only to the extent that such exercise of the Option would not result in an

                                      -2-




accounting compensation charge with respect to the Shares used to pay the
exercise price); or

        (d) payment through a broker-dealer sale and remittance procedure
pursuant to which the Grantee (i) provides written instructions to a
Company-designated brokerage firm to effect the immediate sale of some or all of
the purchased Shares and remit to the Company sufficient funds to cover the
aggregate exercise price payable for the purchased Shares and (ii) provides
written directives to the Company to deliver the certificates for the purchased
Shares directly to such brokerage firm in order to complete the sale
transaction.

     5. Restrictions on Exercise. The Option may not be exercised if the
issuance of the Shares subject to the Option upon such exercise would constitute
a violation of any Applicable Laws. In addition, the Option may not be exercised
until such time as the Plan has been approved by the shareholders of the
Company.

     6. Termination or Change of Continuous Service. If the Grantee's Continuous
Service terminates other than for Cause, the Grantee may, but only during the
Post-Termination Exercise Period, exercise the portion of the Option that was
vested at the date of such termination (the "Termination Date"). If the
Grantee's Continuous Service is terminated for Cause, the Grantee's right to
exercise the Option shall, except as otherwise determined by the Administrator,
terminate concurrently with the termination of the Grantee's Continuous Service
(also the "Termination Date"). In no event may the Option be exercised later
than the Expiration Date set forth in the Notice. If the Grantee's status
changes from Employee, Director or Consultant to any other status of Employee,
Director or Consultant, the Option shall remain in effect and vesting of the
Option shall continue only to the extent determined by the Administrator as of
such change in status; provided, however, with respect to any Incentive Stock
Option that remains in effect after a change in status from Employee to Director
or Consultant, such Incentive Stock Option shall cease to be treated as an
Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on
the day three (3) months and one (1) day following such change in status. Except
as provided in Sections 7 and 8 below, to the extent that the Option was
unvested on the Termination Date, such unvested portion of the Option shall
terminate. In addition, except as provided in Sections 7 and 8 below, if the
Grantee does not exercise the vested portion of the Option within the
Post-Termination Exercise Period, such vested portion of the Option shall
terminate.

     7. Disability of Grantee. If the Grantee's Continuous Service terminates as
a result of his or her Disability, the Grantee may, but only within twelve (12)
months from the Termination Date (and in no event later than the Expiration
Date), exercise the portion of the Option that was vested on the Termination
Date; provided, however, that if such Disability is not a "disability" as such
term is defined in Section 22(e)(3) of the Code and the Option is an Incentive
Stock Option, such Incentive Stock Option shall cease to be treated as an
Incentive Stock Option and shall be treated as a Non-Qualified Stock Option on
the day three (3) months and one (1) day following the Termination Date. To the
extent that the Option was unvested on the Termination Date, such unvested
portion of the Option shall terminate. In addition, if the Grantee does not
exercise the vested portion of the Option within the time specified herein, such
vested portion of the Option shall terminate. Section 22(e)(3) of the Code
provides that an individual is permanently and totally disabled if he or she is
unable to engage in any substantial gainful activity by reason of any medically

                                      -3-




determinable physical or mental impairment which can be expected to result in
death or which has lasted or can be expected to last for a continuous period of
not less than twelve (12) months.

     8. Death of Grantee. If the Grantee's Continuous Service terminates as a
result of his or her death, or in the event of the Grantee's death during the
Post-Termination Exercise Period or during the twelve (12) month period
following the Grantee's termination of Continuous Service as a result of his or
her Disability, the Grantee's estate, or a person who acquired the right to
exercise the Option by bequest or inheritance, may exercise the portion of the
Option that was vested at the Termination Date, within twelve (12) months from
the date of death (but in no event later than the Expiration Date). To the
extent that the Option was unvested on the date of death, such unvested portion
of the Option shall terminate. In addition, if the vested portion of the Option
is not exercised within the time specified herein, such vested portion of the
Option shall terminate.

     9. Transferability of Option. The Option, if an Incentive Stock Option, may
not be transferred in any manner other than by will or by the laws of descent
and distribution and may be exercised during the lifetime of the Grantee only by
the Grantee. The Option, if a Non-Qualified Stock Option, may not be transferred
in any manner other than by will or by the laws of descent and distribution,
provided, however, that a Non-Qualified Stock Option may be transferred to
members of the Grantee's Immediate Family to the extent and in the manner
authorized by the Administrator. The terms of the Option shall be binding upon
the executors, administrators, heirs and successors of the Grantee.

     10. Term of Option. The Option must be exercised no later than the
Expiration Date set forth in the Notice or such earlier date as otherwise
provided herein. After the Expiration Date or such earlier date, the Option
shall be of no further force or effect and may not be exercised.

     11. Stop-Transfer Notices. In order to ensure compliance with the
restrictions on transfer set forth in this Option Agreement, the Notice or the
Plan, the Company may issue appropriate "stop transfer" instructions to its
transfer agent, if any, and, if the Company transfers its own securities, it may
make appropriate notations to the same effect in its own records.

     12. Refusal to Transfer. The Company shall not be required (i) to transfer
on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Option Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares have been so transferred.

     13. Tax Consequences. Set forth below is a brief summary as of the date of
this Option Agreement of some of the federal tax consequences of exercise of the
Option and disposition of the Shares. This summary is necessarily incomplete,
and the tax laws and regulations are subject to change. The Grantee should
consult a tax adviser before exercising the Option or disposing of the Shares.

                                      -4-




        (a) Exercise of Incentive Stock Option. If the Option qualifies as an
Incentive Stock Option, there will be no regular federal income tax liability
upon the exercise of the Option, although the excess, if any, of the Fair Market
Value of the Shares on the date of exercise over the Exercise Price will be
treated as income for purposes of the alternative minimum tax for federal tax
purposes and may subject the Grantee to the alternative minimum tax in the year
of exercise. However, the Internal Revenue Service issued proposed regulations
that would subject the Grantee to withholding at the time the Grantee exercises
an Incentive Stock Option for Social Security and Medicare based upon the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price. These proposed regulations are subject to further
modification by the Internal Revenue Service and, if adopted, would be effective
only for the exercise of an Incentive Stock Option that occurs two years after
the regulations are issued in final form.

        (b) Exercise of Incentive Stock Option Following Disability. If the
Grantee's Continuous Service terminates as a result of Disability that is not
permanent and total disability as such term is defined in Section 22(e)(3) of
the Code, to the extent permitted on the date of termination, the Grantee must
exercise an Incentive Stock Option within three (3) months of such termination
for the Incentive Stock Option to be qualified as an Incentive Stock Option.
Section 22(e)(3) of the Code provides that an individual is permanently and
totally disabled if he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than twelve (12) months.

        (c) Exercise of Non-Qualified Stock Option. On exercise of a
Non-Qualified Stock Option, the Grantee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the Fair Market Value of the Shares on the date of exercise over the
Exercise Price. If the Grantee is an Employee or a former Employee, the Company
will be required to withhold from the Grantee's compensation or collect from the
Grantee and pay to the applicable taxing authorities an amount in cash equal to
a percentage of this compensation income at the time of exercise, and may refuse
to honor the exercise and refuse to deliver Shares if such withholding amounts
are not delivered at the time of exercise.

        (d) Disposition of Shares. In the case of a Non-Qualified Stock Option,
if Shares are held for more than one year, any gain realized on disposition of
the Shares will be treated as long-term capital gain for federal income tax
purposes. In the case of an Incentive Stock Option, if Shares transferred
pursuant to the Option are held for more than one year after receipt of the
Shares and are disposed more than two years after the Date of Award, any gain
realized on disposition of the Shares also will be treated as capital gain for
federal income tax purposes and subject to the same tax rates and holding
periods that apply to Shares acquired upon exercise of a Non-Qualified Stock
Option. If Shares purchased under an Incentive Stock Option are disposed of
prior to the expiration of such one-year or two-year periods, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the Exercise Price and the
lesser of (i) the Fair Market Value of the Shares on the date of exercise, or
(ii) the sale price of the Shares.


                                      -5-



     14. Lock-Up Agreement. (a) Agreement. The Grantee, if such person is an
officer, director or owner of greater than 5% of the Common Stock of the Company
at such time (including, for purposes of determining stock ownership, shares of
Common Stock issuable upon exercise of options or warrants, or conversion of
securities convertible into shares of Common Stock), and if requested by the
Company and the lead underwriter of any public offering of the Common Stock (the
"Lead Underwriter"), hereby irrevocably agrees not to sell, contract to sell,
grant any option to purchase, transfer the economic risk of ownership in, make
any short sale of, pledge or otherwise transfer or dispose of any interest in
any Common Stock or any securities convertible into or exchangeable or
exercisable for or any other rights to purchase or acquire Common Stock (except
Common Stock included in such public offering or acquired on the public market
after such offering) during the 180-day period following the effective date of a
registration statement of the Company filed under the Securities Act of 1933, as
amended, or such shorter period of time as the Lead Underwriter may specify. The
Grantee further agrees to sign such documents as may be requested by the Lead
Underwriter to effect the foregoing and agrees that the Company may impose
stop-transfer instructions with respect to such Common Stock subject to the
lock-up period until the end of such period. The Company and the Grantee
acknowledge that each Lead Underwriter of a public offering of the Company's
stock, during the period of such offering and for the 180-day period thereafter,
is an intended beneficiary of this Section 14.

         (b) No Amendment Without Consent of Underwriter. During the period from
identification of a Lead Underwriter in connection with any public offering of
the Company's Common Stock until the earlier of (i) the expiration of the
lock-up period specified in Section 14(a) in connection with such offering or
(ii) the abandonment of such offering by the Company and the Lead Underwriter,
the provisions of this Section 14 may not be amended or waived except with the
consent of the Lead Underwriter.

     15. Code Section 409A Matters. This option is not intended to constitute
"nonqualified deferred compensation" within the meaning of Code Section 409A,
but rather is intended to be exempt from the application of Code Section 409A.
To the extent that this option is nevertheless deemed to be subject to Code
Section 409A for any reason, this option shall be interpreted in accordance with
Code Section 409A and Department of Treasury regulations and other interpretive
guidance issued thereunder, including without limitation any such regulations or
other guidance that may be issued after the date on which this option was
granted (the "Grant Date"). Notwithstanding any provision herein to the
contrary, in the event that following the Grant Date, the Administrator (as
defined in the Plan) determines that this option may be or become subject to
Code Section 409A, the Administrator may adopt such amendments to the Plan
and/or this option or adopt other policies and procedures (including amendments,
policies and procedures with retroactive effect), or take any other actions that
the Administrator determines are necessary or appropriate to (a) exempt the Plan
and/or this option from the application of Code Section 409A and/or preserve the
intended tax treatment of the benefits provided with respect to this option, or
(b) comply with the requirements of Code Section 409A. In the event this Option
and or the Award is deemed to be "nonqualified deferred compensation" as defined
in Code Section 409A, the value of such nonqualified deferred compensation could
become taxable to Grantee, and Grantee agrees to assume and take full
responsibility for any such tax consequences.

                                      -6-



     16. Entire Agreement: Governing Law. The Notice, the Plan and this Option
Agreement constitute the entire agreement of the parties with respect to the
subject matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and the Grantee with respect to the subject matter
hereof, and may not be modified adversely to the Grantee's interest except by
means of a writing or writings (including an electronic or facsimile
transmission) signed by the Company and the Grantee. Nothing in the Notice, the
Plan or this Option Agreement (except as expressly provided therein) is intended
to confer any rights or remedies on any persons other than the parties. The
Notice, the Plan and this Option Agreement are to be construed in accordance
with and governed by the internal laws of the State of Colorado without giving
effect to any choice of law rule that would cause the application of the laws of
any jurisdiction other than the internal laws of the State of Colorado to the
rights and duties of the parties. Should any provision of the Notice, the Plan
or this Option Agreement be determined by a court of law to be illegal or
unenforceable, such provision shall be enforced to the fullest extent allowed by
law and the other provisions shall nevertheless remain effective and shall
remain enforceable.

     17. Headings. The captions used in the Notice and this Option Agreement are
inserted for convenience and shall not be deemed a part of the Option for
construction or interpretation.

     18. Dispute Resolution. The provisions of this Section 18 shall be the
exclusive means of resolving disputes arising out of or relating to the Notice,
the Plan and this Option Agreement. The Company, the Grantee and the Grantee's
assignees (the "parties") shall attempt in good faith to resolve any disputes
arising out of or relating to the Notice, the Plan and this Option Agreement by
negotiation between individuals who have authority to settle the controversy.
Negotiations shall be commenced by either party by notice of a written statement
of the party's position and the name and title of the individual who will
represent the party. Within thirty (30) days of the written notification, the
parties shall meet at a mutually acceptable time and place, and thereafter as
often as they reasonably deem necessary, to resolve the dispute. If the dispute
is not resolved by negotiation within ninety (90) days of the written
notification, the parties agree that any suit, action, or proceeding arising out
of or relating to the Notice, the Plan or this Option Agreement shall be brought
in the United States District Court for the District of Colorado (or should such
court lack jurisdiction to hear such action, suit or proceeding, in a Colorado
state court in Arapahoe County, Colorado) and that the parties shall submit to
the jurisdiction of such court. The parties irrevocably waive, to the fullest
extent permitted by law, any objection the party may have to the laying of venue
for any such suit, action or proceeding brought in such court. The parties also
expressly waive any right they have or may have to a jury trial of any such
suit, action or proceeding. If any one or more provisions of this Section 18
shall for any reason be held invalid or unenforceable, it is the specific intent
of the parties that such provisions shall be modified to the minimum extent
necessary to make it or its application valid and enforceable.

     19. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given, (i) when delivered personally;
(ii) when sent by facsimile, with written confirmation of receipt by the sending
facsimile machine; (iii) when sent by electronic transmission, upon written
confirmation of receipt by the receiving party; (iv) five business days after

                                      -7-




being sent by registered or certified mail, return receipt requested, postage
prepaid; or (v) two business days after deposit with a private industry express
courier, with written confirmation of receipt, addressed to the other party at
its address as shown in these instruments, or to such other address as such
party may designate in writing from time to time to the other party.

ADA-ES, Inc.
8100 SouthPark Way, Unit B
Littleton, CO  80120

Attention:  Secretary

     1. Effective as of today, ______________, the undersigned ("Grantee")
hereby elects to exercise the Grantee's option to purchase ___________ shares of
the Common Stock (the "Shares") of ADA-ES, Inc. (the "Company") under and
pursuant to the Company's 2007 Equity Incentive Plan, as amended from time to
time (the "Plan") and the [ ] Incentive [ ] Non-Qualified Stock Option Award
Agreement (the "Option Agreement") and Notice of Stock Option Award (the
"Notice") dated ______________, ________. Unless otherwise defined herein, the
terms defined in the Plan shall have the same defined meanings in this Exercise
Notice.

     2. Representations of the Grantee. The Grantee acknowledges that the
Grantee has received, read and understood the Notice, the Plan and the Option
Agreement and agrees to abide by and be bound by their terms and conditions.
Grantee further represents and warrants that: Grantee has such knowledge and
experience in financial and business matters and/or that Grantee has employed a
purchaser representative who has such knowledge and experience in financial and
business matters such that Grantee is capable of evaluating, either alone or
together with such purchaser representative engaged by Grantee, the merits and
risks of exercising the Option and owning the Shares; and (ii) that Grantee is
acquiring the Shares subject to the Option for his or her own account and not
with any present intention of selling or otherwise distributing the Common
Stock, unless the Shares are registered under the Securities Act of 1933, as
amended, in which case Grantee will be free to immediately sell the Shares into
any market which may exist therefor.

     3. Rights as Shareholder. Until the stock certificate evidencing such
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a shareholder shall exist with
respect to the Shares, notwithstanding the exercise of the Option. The Company
shall issue (or cause to be issued) such stock certificate promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the stock certificate is issued,
except as provided in Section 10 of the Plan.

     The Grantee shall enjoy rights as a shareholder until such time as the
Grantee disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal or the Repurchase Right. Upon such exercise, the
Grantee shall have no further rights as a holder of the Shares so purchased
except the right to receive payment for the Shares so purchased in accordance
with the provisions of the Option Agreement, and the Grantee shall forthwith




cause the certificate(s) evidencing the Shares so purchased to be surrendered to
the Company for transfer or cancellation.

     4. Shareholders Agreement. As a condition precedent to the exercise of the
Option, the Grantee agrees to deliver to the Company an executed Shareholders
Agreement in the form existing at the time of exercise of the Option (as
modified by the Company in its discretion).

     5. Delivery of Payment. The Grantee herewith delivers to the Company the
full Exercise Price for the Shares, which, to the extent selected, shall be
deemed to be satisfied by use of the broker-dealer sale and remittance procedure
to pay the Exercise Price provided in Section 4(d) of the Option Agreement.

     6. Tax Consultation. The Grantee understands that the Grantee may suffer
adverse tax consequences as a result of the Grantee's purchase or disposition of
the Shares. The Grantee represents that the Grantee has consulted with any tax
consultants the Grantee deems advisable in connection with the purchase or
disposition of the Shares and that the Grantee is not relying on the Company for
any tax advice.

     7. Taxes. The Grantee agrees to satisfy all applicable federal, state and
local income and employment tax withholding obligations and herewith delivers to
the Company the full amount of such obligations or has made arrangements
acceptable to the Company to satisfy such obligations. In the case of an
Incentive Stock Option, the Grantee also agrees, as partial consideration for
the designation of the Option as an Incentive Stock Option, to notify the
Company in writing within thirty (30) days of any disposition of any shares
acquired by exercise of the Option if such disposition occurs within two (2)
years from the Date of Award or within one (1) year from the date the Shares
were transferred to the Grantee. If the Company is required to satisfy any
federal, state or local income or employment tax withholding obligations as a
result of such an early disposition, the Grantee agrees to satisfy the amount of
such withholding in a manner that the Administrator prescribes.

     8. Restrictive Legends. The Grantee understands and agrees that unless the
Shares are presently registered under the Securities Act of 1933, as amended,
the Company may cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of
the Shares together with any other legends that may be required by the Company
or by state or federal securities laws:

        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR ANY STATE
        SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR OTHERWISE
        TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
        REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
        SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER,
        SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
        THEREWITH.

                                      -2-




     9. Successors and Assigns. The Company may assign any of its rights under
this Exercise Notice to single or multiple assignees, and this agreement shall

the restrictions on transfer herein set forth, this Exercise Notice shall be
binding upon the Grantee and his or her heirs, executors, administrators,
successors and assigns.

interpretation.

Agreement shall be the exclusive means of resolving disputes arising out of or
relating to this Exercise Notice.

     12. Governing Law; Severability. This Exercise Notice is to be construed in
accordance with and governed by the internal laws of the State of Colorado
without giving effect to any choice of law rule that would cause the application
of the laws of any jurisdiction other than the internal laws of the State of
Colorado to the rights and duties of the parties. Should any provision of this
Exercise Notice be determined by a court of law to be illegal or unenforceable,
such provision shall be enforced to the fullest extent allowed by law and the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     13. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given (i) when delivered personally;
(ii) when sent by facsimile, with written confirmation of receipt by the sending
facsimile machine; (iii) when sent by electronic transmission, upon written

such party may designate in writing from time to time to the other party.

     14. Further Instruments. The parties agree to execute such further
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this agreement.

     15. Entire Agreement. The Notice, the Plan, the Option Agreement and
Shareholders Agreement, if any, are incorporated herein by reference and
together with this Exercise Notice constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and the Grantee
with respect to the subject matter hereof, and may not be modified adversely to
the Grantee's interest except by means of a writing or writings (including an
electronic or facsimile transmission) signed by the Company and the Grantee.
Nothing in the Notice, the Plan, the Option Agreement and this Exercise Notice
(except as expressly provided therein) is intended to confer any rights or
remedies on any persons other than the parties.

                                 --------------------------------------

In connection with the purchase of the above-described securities (the
"Shares"), the undersigned Grantee represents to the Company the following:

     (a) Grantee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares. Grantee is acquiring
these Shares for investment for Grantee's own account only and not with a view
to, or for resale in connection with, any "distribution" thereof within the
meaning of the Securities Act of 1933, as amended (the "Securities Act").

     (b) Grantee acknowledges and understands that unless the Shares are
registered under the Securities Act of 1933, as amended (the "Securities Act"),
the shares will constitute "restricted securities" under the Securities Act and
will have not been registered under the Securities Act in reliance upon a
specific exemption therefrom, which exemption depends upon among other things,
the bona fide nature of Grantee's investment intent as expressed herein. Grantee
further understands that the Shares must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available. Grantee further acknowledges and understands that the
Company is under no obligation to register the Shares. Grantee understands that
unless the Shares are registered under the Securities Act at the time of
issuance, the certificate evidencing the Shares will be imprinted with a legend
which prohibits the transfer of the Shares unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the
Company.

     (c) Grantee is familiar with the provisions of Rule 144, each promulgated
under the Securities Act, which, in substance, permit limited public resale of
"restricted securities" acquired, directly or indirectly from the issuer
thereof, in a non-public offering subject to the satisfaction of certain
conditions.

     If the shares are not registered for resale under an effective registration
statement on file with the Securities and Exchange Commission at the time of the
exercise of the Option, then the Shares may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Shares were sold
by the Company or the date the Shares were sold by an affiliate of the Company,
within the meaning of Rule 144; and, in the case of acquisition of the Shares by
an affiliate, or by a non-affiliate who subsequently holds the Shares less than
two (2) years, the satisfaction of the conditions set forth in sections (1),
(2), (3) and (4) of the paragraph immediately above.




     (d) Grantee further understands that if all of the applicable requirements
of Rule 144 are not satisfied, that registration under the Securities Act,
compliance with Regulation A or some other registration exemption will be
required and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the Securities and Exchange Commission has expressed its opinion that
persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rules 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.
Grantee understands that no assurances can be given that any such other
registration exemption will be available in such event.

     (e) Grantee represents that Grantee is a resident of the state of
___________________.

                          Addendum to the ADA-ES, Inc.
                           2007 Equity Incentive Plan
                                Option Agreement

                          For California Residents Only

     This Addendum is intended to comply with Section 25102(o) of the California
Corporations Code and any rules or regulations promulgated thereunder by the
California Department of Corporations. Any provision of the Plan or any Option
Agreement which is otherwise inconsistent with this Addendum or Section 25102(o)
of the California Securities Code shall, without further act or amendment by the
Company, be reformed to comply with Section 25102(o) of the California
Securities Code. Both the Common Stock and the Options that are the subject of
this Addendum if not yet qualified with the California Department of
Corporations and not yet exempt from such qualification, are subject to such
qualification, and the issuance of the Options prior to the qualification is
unlawful unless such issuance is exempt. The rights of the Company and the
Option holder with respect to Options that are the subject of this Addendum are
expressly conditioned on such exemption being available.

     In addition to those provisions set forth in the Plan, any Option Agreement
and/or the Stockholders Agreement, Options granted to employees of the Company
or an Affiliate resident in California ("California Employees") will be subject
to the following provisions:

     1.   Each California Employee will receive financial statements of the
          Company annually during the period such California Employee has
          Options outstanding. This requirement does not apply to California
          Employees who are key employees whose duties in connection with the
          Company or an Affiliate assure them access to equivalent information.

     2.   California Employees will have the right to exercise at least 20% of
          their Options per year over 5 years from the date the Options are
          granted, subject to reasonable conditions such as continued
          employment. However, in the case of Options granted to California
          Employees who are officers, directors, managers, or consultants of the
          Company or an Affiliate, the Options may become fully exercisable,
          subject to reasonable conditions such as continued employment, at any
          time or during any period established by the Company or an Affiliate.

     3.   Unless employment of a California Employee is terminated "for cause"
          under applicable law, the terms of the Plan, the Option Agreement, the
          Option grant or California Employee's contract of employment, the
          right to exercise the California Employee's Option in the event of
          termination of his or her employment, to the extent the California
          Employee is entitled to exercise such Option on the date his or her
          employment terminates, shall be as follows:




     (i)  Such Option may be exercised for at least 6 months from the date of
          such termination, if termination was caused by death or Disability.

     (ii) Such Option may be exercised for at least 30 days from the date of
          such termination if termination was caused by other than death or
          Disability.

     Notwithstanding the foregoing, such Option may not be exercised after the
expiration of the stated period of the Option.

     4. At the discretion of the Committee, the Company may reserve to itself
and/or its assignee in the Option Agreement, or any other agreement with the
California Employee, a right to repurchase Common Stock held by a California
Employee or his or her transferee in the event of such California Employee's
termination of employment with the Company or an Affiliate at any time within 90
days after the date of such termination (or in the case of Common Stock issued
upon exercise of an Option after such termination date, within 90 days after the
date of such exercise) for cash or cancellation of purchase money indebtedness,
at:

          (A)  no less than the Fair Market Value of such Common Stock as of the
               date of such termination of employment, provided that such right
               to repurchase Common Stock terminates when the common Stock has
               become publicly traded; or

          (B)  the Option holder's original purchase price, provided that such
               right to repurchase Common Stock at the original purchase price
               lapses at the rate of at lease 20% of the Common Stock subject to
               the Option per year over 5 years from the date the Option is
               granted (without respect to the date the Option was exercised or
               became exercisable).

     Notwithstanding the foregoing, the Common Stock held by a California
Employee who is an officer, director, manager or consultant of the Company or an
Affiliate may be subject to additional or greater restrictions than those set
forth in this item 4 above.

          o    25% of the Total Number of Shares of Common Stock Awarded shall

               Grantee's termination of the leave of absence and return to

     For purposes of this Notice and the Agreement, the term "vest" shall mean,
with respect to any Shares, that such Shares are no longer subject to repurchase

remain subject to other restrictions on transfer set forth in the Agreement or

Transaction or Change of Control.

upon the issuance of the Shares to the Grantee hereunder.

     2. Method of Payment. Payment of the Total Purchase Price shall be by any

               Grantee;

         (iii) The Grantee shall be personally liable for payment of the

               satisfactory to the Administrator with such documentation as the
               Administrator may request; and



          (iv) The promissory note shall become due and payable upon the
               occurrence of any or all of the following events: (A) the sale or
               transfer of the Shares purchased with the promissory note; (B)
               termination of the Grantee's Continuous Service for any reason
               other than death or disability; or (C) the first anniversary of
               the termination of the Grantee's Continuous Service due to death
               or disability.

          NOTE: If the Company is going to extend credit, it must confirm that
          it complies with any applicable Federal Reserve requirements relating
          to the extension of credit

     3. Transfer Restrictions. The Shares sold to the Grantee hereunder may not
be sold, transferred by gift, pledged, hypothecated, or otherwise transferred or
disposed of by the Grantee prior to the date when the Shares become vested
pursuant to the Vesting Schedule set forth in the Notice. Any attempt to
transfer Restricted Shares in violation of this Section 3 will be null and void
and will be disregarded. Before the Shares fully vest, the Shares will be
subject to the Company's Repurchase Rights as set forth in Section 9 below.

     4. Escrow of Stock. For purposes of facilitating the enforcement of the
provisions of this Agreement, the Grantee agrees, immediately upon receipt of
the certificate(s) for the Restricted Shares, to deliver such certificate(s),
together with an Assignment Separate from Certificate in the form attached
hereto as Exhibit A, executed in blank by the Grantee and the Grantee's spouse
(if required for transfer) with respect to each such stock certificate, to the
Secretary or Assistant Secretary of the Company, or their designee, to hold in
escrow for so long as such Restricted Shares have not vested pursuant to the
Vesting Schedule set forth in the Notice and continue to be subject to the
Company's Repurchase Rights, with the authority to take all such actions and to
effectuate all such transfers and/or releases as may be necessary or appropriate
to accomplish the objectives of this Agreement in accordance with the terms
hereof. The Grantee hereby acknowledges that the appointment of the Secretary or
Assistant Secretary of the Company (or their designee) as the escrow holder
hereunder with the stated authorities is a material inducement to the Company to
make this Agreement and that such appointment is coupled with an interest and is
accordingly irrevocable. The Grantee agrees that such escrow holder shall not be
liable to any party hereto (or to any other party) for any actions or omissions
unless such escrow holder is grossly negligent relative thereto. The escrow
holder may rely upon any letter, notice or other document executed by any
signature purported to be genuine and may resign at any time. Upon the vesting
of all Restricted Shares and termination of the Company's Right of First
Refusal and Repurchase Right, the escrow holder will, without further order
or instruction, transmit to the Grantee the certificate evidencing such Shares,
subject, however, to satisfaction of any withholding obligations provided in
Section 6 below, and subject to the terms of any security agreement executed in
connection with the purchase of the Shares by means of a promissory note.

                                       2


     5. Distributions. Except as set forth in Section 9(e), the Company shall
disburse to the Grantee all dividends and other distributions paid or made in
cash with respect to the Shares and Additional Securities (whether vested or
not), less any applicable withholding obligations.

     6. Section 83(b) Election and Withholding of Taxes. The Grantee shall
provide the Administrator with a copy of any timely election made pursuant to
Section 83(b) of the Internal Revenue Code or similar provision of state law
(collectively, an "83(b) Election"), a form of which is attached hereto as
Exhibit B. If the Grantee makes a timely 83(b) Election, the Grantee shall
immediately pay the Company the amount necessary to satisfy any applicable
foreign, federal, state, and local income and employment tax withholding
obligations. If the Grantee does not make a timely 83(b) Election, the Grantee
shall, as Restricted Shares vest, or at the time withholding is otherwise
required by any Applicable Law, pay the Company the amount necessary to satisfy
any applicable foreign, federal, state, and local income and employment tax
withholding obligations. The Grantee may satisfy his or her withholding
obligations by authorizing the Company to transfer to the Company the number of
vested Shares held in escrow that have an aggregate Fair Market Value equal to
the withholding obligations. The Grantee hereby represents that he or she
understands (a) the contents and requirements of the 83(b) Election, (b) the
application of Section 83(b) to the receipt of the Shares by the Grantee
pursuant to this Agreement, (c) the nature of the election to be made by the
Grantee under Section 83(b) and the consequences of either making or not making
the 83(b) Election, and (d) the effect and requirements of the 83(b) Election
under relevant state and local tax laws. The Grantee further represents that he
or she intends OR does not intend to file an election pursuant to Section 83(b)
with the Internal Revenue Service within thirty (30) days following the date of
this Agreement, and submit a copy of such election with his or her federal tax
return for the calendar year in which the date of this Agreement falls.

[NOTE: Grantee must cross through the inapplicable language in the preceding
paragraph, and initial here: .]

     7. Additional Securities. Any securities received as the result of
ownership of the Restricted Shares (the "Additional Securities"), including, but
not by way of limitation, warrants, options and securities received as a stock
dividend or stock split, or as a result of a recapitalization or reorganization
or other similar change in the Company's capital structure, shall be retained in
escrow in the same manner and subject to the same conditions and restrictions as
the Restricted Shares with respect to which they were issued, including, without
limitation, the Vesting Schedule set forth in the Notice and the Company's
Repurchase Rights. The Grantee shall be entitled to direct the Company to
exercise any warrant, option or other right received as Additional Securities
upon supplying the funds necessary to do so, in which event the securities so
purchased shall constitute Additional Securities, but the Grantee may not direct

                                       3


the Company to sell any such warrant, option or right. If Additional Securities
consist of a convertible security, the Grantee may exercise any conversion
right, and any securities so acquired shall constitute Additional Securities.
Appropriate adjustments to reflect the distribution of Additional Securities
shall be made to the price per share to be paid upon the exercise of the
Repurchase Right in order to reflect the effect of any such transaction upon the
Company's capital structure. In the event of any change in certificates
evidencing the Shares or the Additional Securities by reason of any
recapitalization, reorganization or other transaction that results in the
creation of Additional Securities, the escrow holder is authorized to deliver to
the issuer the certificates evidencing the Shares or the Additional Securities
in exchange for the certificates of the replacement securities.

     8. Company's Repurchase Rights. (a) Grant of Repurchase Rights. The Company
is hereby granted the right to repurchase all or any portion of the Shares that
are Restricted Shares (the "Repurchase Right") exercisable at any time during
the period commencing on the date the Grantee's Continuous Service terminates
for any reason, with or without cause (including death or disability) (the
"Termination Date") and ending ninety (90) days after the first date on which
the Repurchase Right may be exercised without incurring an accounting expense
with respect to such exercise (the "Share Repurchase Period").

          (b) Exercise of the Repurchase Right. The Repurchase Right shall be
exercisable by written notice delivered to the Grantee prior to the expiration
of the Share Repurchase Period. The notice shall indicate the number of Shares
to be repurchased and the date on which the repurchase is to be effected, such
date to be not later than the last day of the Share Repurchase Period. On the
date on which the repurchase is to be effected, the Company and/or its assigns
shall pay to the Grantee in cash or cash equivalents (including the cancellation
of any purchase-money indebtedness) for Restricted Shares being repurchased, the
Purchase Price per Share previously paid by the Grantee to the Company for such
Shares. Upon such payment to the Grantee or into escrow for the benefit of the
Grantee, the Company and/or its assigns shall become the legal and beneficial
owner of the Shares being repurchased and all rights and interest thereon or
related thereto, and the Company shall have the right to transfer to its own
name or its assigns the number of Shares being repurchased, without further
action by the Grantee.

          (c) Assignment. Whenever the Company shall have the right to purchase
Shares under this Repurchase Right, the Company may designate and assign one or
more employees, officers, directors or shareholders of the Company or other
persons or organizations, to exercise all or a part of the Company's Repurchase
Right.

          (d) Termination of the Repurchase Right. The Repurchase Right shall
terminate with respect to any Shares for which it is not timely exercised. In
addition, the Repurchase Right shall terminate, and cease to be exercisable,
with respect to all vested Shares upon the date on which such shares cease to be
Restricted Shares.

          (e) Corporate Transaction/ Change of Control. Immediately prior to the
consummation of a Corporate Transaction described in Section 2(q)(i), (ii) or
(iii) of the Plan or a Change of Control, the Repurchase Right as to all vested
Shares shall automatically lapse in its entirety, except to the extent this
Agreement is Assumed, in which case the Repurchase Right shall apply to the new
capital stock or other property received in exchange for the vested Shares in

                                       4


consummation of the Corporate Transaction or Change of Control, but only to the
extent the vested Shares are at the time covered by such right. The Repurchase
Right as to Restricted Shares shall apply to the new capital stock or other
property (including cash paid other than as a regular cash dividend) received in
exchange for the Shares in consummation of the Corporate Transaction and such
stock or property shall be deemed Additional Securities for purposes of this
Agreement, but only to the extent the Shares are at the time covered by such
Repurchase Right. Appropriate adjustments shall be made to the price per share
payable upon exercise of the Repurchase Right to reflect the effect of the
Corporate Transaction or Related Entity Disposition.

NOTE: This section does not contemplate the termination of the Repurchase
Right for unvested Shares upon a Corporate Transaction or Related Entity
Disposition. If the Repurchase Right for unvested Shares were to terminate on an
acquisition, the Award is in effect "accelerated," in that the Grantee would
receive full consideration for the shares on a Corporate Transaction although
the vesting time periods have not elapsed. Consideration should be given to
whether either of the following provisions should be added to all agreements or
to agreements for specific individuals. To the extent that this Agreement will
not be Assumed, the Repurchase Right as to such Restricted Shares shall
automatically lapse. Another possibility is to give the Company the option to
repurchase the unvested Shares (at the Exercise Price per Share for the unvested
Shares) in a Corporate Transaction if the Agreement is not Assumed. [Such a
provision would mean that the Grantee only receives the acquisition
consideration for the vested shares and results in the Grantee receiving the
consideration that he would have received if he had vested options rather than
purchased shares.] To the extent that this Agreement is not Assumed, the
Company shall have the Repurchase Right as to such Restricted Shares pursuant to
Section 9(a) of this Agreement, except that the Share Repurchase Period shall be
the sixty (60) day period immediately preceding the consummation of the
Corporate Transaction or Related Entity Disposition.

     9. Stop-Transfer Notices. In order to ensure compliance with the
restrictions on transfer set forth in this Agreement, the Notice or the Plan,
the Company may issue appropriate "stop transfer" instructions to its transfer
agent, if any, and, if the Company transfers its own securities, it may make
appropriate notations to the same effect in its own records.

     10. Refusal to Transfer. The Company shall not be required (i) to transfer
on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

     11. Restrictive Legends. Grantee understands and agrees that the Company
may cause the legends set forth below or legends substantially equivalent
thereto, to be placed upon any certificate(s) evidencing ownership of the
Shares, as applicable, together with any other legends that may be required by
the Company or by state or federal securities laws:

                                       5


     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
     SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
     UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL
     SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE
     OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
     RESTRICTIONS ON TRANSFER, A REPURCHASE RIGHT HELD BY THE ISSUER
     OR ITS ASSIGNEE(S) AS SET FORTH IN THE RESTRICTED STOCK PURCHASE
     AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE
     SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE
     OF THE ISSUER SUCH TRANSFER RESTRICTIONS AND REPURCHASE RIGHT ARE
     BINDING ON TRANSFEREES OF THESE SHARES.

     12. Lock-Up Agreement. (a) Agreement. Grantee, if such person is an
officer, director or owner of greater than 5% of the Common Stock of the Company
at such time (including, for purposes of determining stock ownership, shares of
Common Stock issuable upon exercise of options or warrants, or conversion of
securities convertible into shares of Common Stock), and if requested by the
Company and the lead underwriter of any public offering of the Common Stock or
other securities of the Company (the "Lead Underwriter"), hereby irrevocably
agrees not to sell, contract to sell, grant any option to purchase, transfer the
economic risk of ownership in, make any short sale of, pledge or otherwise
transfer or dispose of any interest in any Common Stock or any securities
convertible into or exchangeable or exercisable for or any other rights to
purchase or acquire Common Stock (except Common Stock included in such public
offering or acquired on the public market after such offering) during the
180-day period following the effective date of a registration statement of the
Company filed under the Securities Act of 1933, as amended, or such shorter
period of time as the Lead Underwriter shall specify. Grantee further agrees to
sign such documents as may be requested by the Lead Underwriter to effect the
foregoing and agrees that the Company may impose stop-transfer instructions with
respect to such Common Stock subject until the end of such period. The Company
and Grantee acknowledge that each Lead Underwriter of a public offering of the
Company's stock, during the period of such offering and for the 180-day period
thereafter, is an intended beneficiary of this Section 13.

          (b) No Amendment Without Consent of Underwriter. During the period
from identification as a Lead Underwriter in connection with any public offering
of the Company's Common Stock until the earlier of (i) the expiration of the
lock-up period specified in Section 13(a) in connection with such offering or
(ii) the abandonment of such offering by the Company and the Lead Underwriter,
the provisions of this Section 13 may not be amended or waived except with the
consent of the Lead Underwriter.

                                       6


     13. Grantee's Representations. In the event the Shares purchasable pursuant
to this Agreement have not been registered under the Securities Act of 1933, as
amended, at the time of purchase, the Grantee shall, if required by the Company,
concurrently with the purchase of the Shares, deliver to the Company his or her
Investment Representation Statement in the form attached hereto as Exhibit C.

     14. Transferability. No benefit payable under, or interest in, this
Agreement or in the shares of Common Stock that are scheduled to be issued
hereunder shall be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance or charge and any such attempted
action shall be void and no such benefit or interest shall be, in any manner,
liable for, or subject to, your or your beneficiary's debts, contracts,
liabilities or torts; provided, however, nothing in this Section 14 shall
prevent transfer (i) by will, (ii) by applicable laws of descent and
distribution or (iii) to an Alternate Payee to the extent that a QDRO so
provides, as further described in Section 20 of the Plan.

     15. No Contract for Employment. This Agreement is not an employment or
service contract and nothing in this Agreement shall be deemed to create in any
way whatsoever any obligation of the Grantee to continue in the employ or
service of the Company, or of the Company to continue to employ Grantee.

     16. Applicability of Plan. This Agreement is subject to all the provisions
of the Plan, which provisions are hereby made a part of this Agreement, and is
further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. In the
event of any conflict between the provisions of this Agreement and those of the
Plan, the provisions of the Plan shall control.

     17. No Compensation Deferral. This Award is not intended to constitute
"nonqualified deferred compensation" within the meaning of Code Section 409A,
but rather is intended to be exempt from the application of Code Section 409A.
To the extent that the Award is nevertheless deemed to be subject to Code
Section 409A for any reason, this Award shall be interpreted in accordance with
Code Section 409A and Department of Treasury regulations and other interpretive
guidance issued thereunder, including without limitation any such regulations or
other guidance that may be issued after the Grant Date. Notwithstanding any
provision herein to the contrary, in the event that following the Grant Date,
the Administrator (as defined in the Plan) determines that the Award may be or
become subject to Code Section 409A, the Administrator may adopt such amendments
to the Plan and/or this Agreement or adopt other policies and procedures
(including amendments, policies and procedures with retroactive effect), or take
any other actions, that the Administrator determines are necessary or
appropriate to (a) exempt the Plan and/or the Award from the application of Code
Section 409A and/or preserve the intended tax treatment of the benefits provided
with respect to this option, or (b) comply with the requirements of Code Section
409A.

     18. Acknowledgement. By electing to accept this Agreement, you acknowledge
receipt of this Agreement and hereby confirm your understanding that the terms
set forth in this Agreement constitute, subject to the terms of the Plan, which
terms shall control in the event of any conflict between the Plan and this
Agreement, the entire agreement and understanding of the parties with respect to
the matters contained herein and supersede any and all prior agreements,
arrangements and understandings, both oral and written, between the parties
concerning the subject matter of this Agreement. The Company may, in its sole
discretion, decide to deliver any documents related to Units awarded under the
Plan or future Units that may be awarded under the Plan by electronic means or
request your consent to participate in the Plan by electronic means. You hereby
consent to receive such documents by electronic delivery and agree to
participate in the Plan through an on-line or electronic system established and
maintained by the Company or another third party designated by the Company.

     19. Entire Agreement: Governing Law. The Notice, the Plan and this
Agreement constitute the entire agreement of the parties with respect to the
subject matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and the Grantee with respect to the subject matter
hereof, and may not be modified adversely to the Grantee's interest except by
means of a writing signed by the Company and the Grantee. These agreements are
to be construed in accordance with and governed by the internal laws of the
State of Delaware, without giving effect to any choice of law rule that would
cause the application of the laws of any jurisdiction other than the internal
laws of the State of Delaware to the rights and duties of the parties. Should
any provision of the Notice or this Agreement be determined by a court of law to
be illegal or unenforceable, the other provisions shall nevertheless remain
effective and shall remain enforceable.

     20. Headings. The captions used in this Agreement are inserted for
convenience and shall not be deemed a part of this Agreement for construction or
interpretation.

     21. Dispute Resolution The provisions of this Section 21 shall be the
exclusive means of resolving disputes arising out of or relating to the Notice,
the Plan and this Agreement. The Company, the Grantee, and the Grantee's
assignees (the "parties") shall attempt in good faith to resolve any disputes
arising out of or relating to the Notice, the Plan and this Agreement by
negotiation between individuals who have authority to settle the controversy.
Negotiations shall be commenced by either party by notice of a written statement
of the party's position and the name and title of the individual who will
represent the party. Within thirty (30) days of the written notification, the
parties shall meet at a mutually acceptable time and place, and thereafter as
often as they reasonably deem necessary, to resolve the dispute. If the dispute
has not been resolved by negotiation, the parties agree that any suit, action,
or proceeding arising out of or relating to the Notice, the Plan or this
Agreement shall be brought in the Courts of the State of Colorado, and the
parties shall submit to the jurisdiction of such courts. The parties irrevocably
waive, to the fullest extent permitted by law, any objection the party may have
to the laying of venue for any such suit, action or proceeding brought in such
court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A
JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions
of this Section 17 shall for any reason be held invalid or unenforceable, it is
the specific intent of the parties that such provisions shall be modified to the
minimum extent necessary to make it or its application valid and enforceable.

                                       8


     22. Compliance with Laws. Notwithstanding anything contained in this
Agreement or the Plan, the Company may not take any actions hereunder, and no
award shall be granted, that would violate the Securities Act of 1933, as
amended (the "Act"), the Securities Exchange Act of 1934, as amended, the Code,
or any other securities or tax or other applicable law or regulation.
Notwithstanding anything to the contrary contained herein, the shares issuable
upon vesting shall not be issued unless such shares are then registered under
the Act, or, if such shares are not then so registered, the Company has
determined that such vesting and issuance would be exempt from the registration
requirements of the Act.

     23. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail (if the parties are within
the United States) or upon deposit for delivery by an internationally recognized
express mail courier service (for international delivery of notice), with
postage and fees prepaid, addressed to the other party at its address as shown
beneath its signature in the Notice, or to such other address as such party may
designate in writing from time to time to the other party.

     In connection with the purchase of the above-listed Securities, the
undersigned Grantee represents to the Company the following:

          (a) Grantee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Grantee is
acquiring these Securities for investment for Grantee's own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

          (b) Grantee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon among other things, the bona fide nature
of Grantee's investment intent as expressed herein. In this connection, Grantee
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Grantee's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future. Grantee further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available. Grantee further acknowledges
and understands that the Company is under no obligation to register the
Securities. Grantee understands that the certificate evidencing the Securities
will be imprinted with a legend which prohibits the transfer of the Securities
unless they are registered or such registration is not required in the opinion
of counsel satisfactory to the Company.

          (c) Grantee is familiar with the provisions of Rule 144 promulgated
under the Securities Act, which, in substance, permit limited public resale of
"restricted securities" acquired, directly or indirectly from the issuer
thereof, in a non-public offering subject to the satisfaction of certain



conditions. The Securities may be resold in certain limited circumstances
subject to the provisions of Rule 144, which requires the resale to occur not
less than one year after the later of the date the Securities were sold by the
Company or the date the Securities were sold by an affiliate of the Company,
within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being sold during any three
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable. Other restrictions may also apply to
sales of the Securities, and Grantee understands that the Securities may not be
readily resold, and that delays may occur in selling the Securities, even if
they are eligible for sale under Rule 144.

          (d) Grantee further understands that in the event all of the
applicable requirements of Rule 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rule 144 is
not exclusive, the Staff of the Securities and Exchange Commission has expressed
its opinion that persons proposing to sell private placement securities other
than in a registered offering and otherwise than pursuant to Rule 144 will have
a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and
their respective brokers who participate in such transactions do so at their own
risk. Grantee understands that no assurances can be given that any such other
registration exemption will be available in such event, and that the Securities
may not be salable by Grantee.

          (e) Grantee represents that he is a resident of the State of
____________________.
