                             TO BE HELD MAY 12, 2005

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 Management and Board of Directors (collectively, the
"Board"), to be voted at the ANNUAL MEETING OF SHAREHOLDRS (the "Meeting") of
the Company to be held on Wednesday, May 12, 2005, at the offices of the Company
at 8100 SouthPark Way, Unit B, Littleton, Colorado. The Company anticipates that
this Proxy Statement and accompanying form of proxy will be first mailed or
given to Shareholders of the Company on our about April 14, 2005. 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.

                         VOTING RIGHTS AND VOTE REQUIRED

The Board of Directors of the Company has fixed the close of business on April
11, 2005 as the record date for determination of Shareholders entitled to notice
of and to vote at the Meeting. As of April 11, 2005 there were 4,834,887 shares
of the Company's 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, which may come before the meeting. The Company has no 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 of Directors 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 Corporations Act or the Company's Articles of
Incorporation. Abstentions will be treated as abstentions and not as a vote
against the proposal. 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. Broker non-votes on a
particular proposal will not be treated as shares present and entitled to vote
on the proposal.

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, (1) the affirmative votes cast must exceed the opposing votes cast to
approve (a) the ADA-ES 2004 Stock Compensation Plan #2 , and (b) the ADA-ES 2005
Directors' Compensation Plan, and (2) the nine nominees receiving the highest
number of votes cast will be elected as Directors.

Unless specified otherwise, each proxy submitted will be voted FOR the proposal
to approve the ADA-ES 2004 Stock Compensation Plan #2, and the ADA-ES 2005
Directors' Compensation Plan, and FOR the persons nominated by Management for
directors of the Company, being Ramon E. Bisque, Duane N. Bloom, Michael D.
Durham, John W. Eaves, Ronald B. Johnson, Robert H. Lowdermilk, Mark H.
McKinnies, Rollie J. Peterson, and Jeffrey C. Smith.

Management knows of no 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, it is the intention of the person named in the
accompanying form of proxy to vote such proxy in accordance with that person's
judgment, including any matter or motion dealing with the conduct of the
Meeting.

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 requesting, in
person, at the Meeting that the proxy be returned.

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

         PROPOSAL TO APPROVE THE ADA-ES 2004 STOCK COMPENSATION PLAN #2

The Company's 2004 Stock Compensation Plan #2 (the "2004 Plan") was adopted by
the Board on November 4, 2004 and authorized the issuance of shares of Common
Stock and/or the grant of options to purchase shares of the Company's Common
Stock to our non-management directors, executive officers and certain employees
and consultants. Pursuant to NASDAQ Marketplace Rule 4350 the grant of shares
and options to our non-management directors, which occurred subsequent to our
NASDAQ listing on October 14, 2004, requires shareholder approval, and
therefore, we are seeking shareholder approval of the 2004 Plan. Regardless of
whether the shareholders approve the 2004 Plan or not, the grant of options
pursuant to the 2004 Plan to our executive officers and certain employees and
consultants will not be effected.

The purpose of the 2004 Plan is to compensate executive officers, certain
employees and consultants, and non-management directors of the Company by
awarding shares and options to purchase shares for services they have and will
render during calendar 2004 and in later years. The 2004 Plan provides for (1)
the award of stock of 603 shares per individual non-management director or 4,221
shares in total, and the grant of options of 5,000 per individual non-management
director or 35,000 in total, (2) the grant of options for a total of 200,000
shares to executive officers of the Company, and (3) the grant of options for a
total of 80,995 shares to certain employees and consultants of the Company. As
noted above, the equity awards and grants to the non-management directors were
made subject to shareholder approval of the 2004 Plan. Options granted under the
2004 Plan to non-management directors may not be exercised, and shares awarded
to non-management directors may not be issued until such shareholder approval
has been obtained, and such options and awards will be null and void if such
shareholder approval is not obtained. The aggregate number of shares of Common
Stock reserved for issuance to non-management directors under the 2004 Plan
totals 39,221 shares (4,221 in the form of stock awards and 35,000 in the form
of options). The grant of options to executive officers, employees and
consultants totaling 280,995 shares pursuant to the 2004 Plan did not require
shareholder approval of the 2004 Plan.

The stock awards and vested portion of the stock option grants to non-management
directors are intended to be a portion of compensation for services performed
from October 2004 through September 2005. The option exercise price of $13.60
per share for the stock options granted on November 4, 2004 was the market price
on the date of the grant. The market price of the Common Stock as of April 1,
2005 was approximately $ 24.00 per share. The options are exercisable over a
period of five years and will vest over a three-year period, one-third each year
for continued service on the Board. If such service is terminated, the
non-vested portion of the option will be forfeited. The 35,000 shares of Common
Stock underlying the options granted and 4,221 shares approved for issuance
pursuant to the Board action of November 4, 2004 were registered with the U.S.
Securities and Exchange on Form S-8 filed December 14, 2004, File No.
333-121234.

The 2004 Plan is contained in a document entitled "ADA-ES, Inc. 2004 Stock
Compensation Plan #2." The continuation of the 2004 Plan is not assumed as a
contractual obligation of the Company, and the right is reserved to the Company,
by action of its Board of Directors, to discontinue the 2004 Plan at any time.
If the 2004 Plan is discontinued, no additional Awards may be made under the
2004 Plan after the date of discontinuance, but the 2004 Plan will continue to
be operated in accordance with its terms, as they may be amended, with respect
to any Awards made prior to the date of discontinuance. Nevertheless, options
granted and shares awarded under the Plan to non-management directors will be
null and void if shareholder approval is not obtained.

The Company, by action of its Board of Directors, has the right at any time,
whether before or after discontinuance of the 2004 Plan, to amend all or any of
the provisions of the 2004 Plan in any manner. Any such amendment may prohibit
or postpone the issuance of any shares of Common Stock even though such shares
may have become issuable after the effective date of the amendment pursuant to
any Award granted before the effective date of the amendment. The 2004 Plan is
administered by the Board of Directors.

The Plan is not subject to the provisions of the Employee Retirement Income
Security Act of 1974, as amended, and therefore is not qualified under Section
401(a) of the Internal Revenue Code of 1986, as amended (the "Code").

The Board recommends that Shareholders vote FOR approval of the ADA-ES 2004
Stock Compensation Plan #2. Assuming a quorum is present at the Meeting, the
affirmative votes cast must exceed the opposing votes cast for the approval of
the ADA-ES 2004 Stock Compensation Plan #2.

THE SHARES OF COMMON STOCK REPRESENTED BY PROXIES IN THE ACCOMPANYING FORM WILL
BE VOTED FOR THE APPROVAL OF THE ADA-ES 2004 STOCK COMPENSATION PLAN #2 UNLESS A
CONTRARY DIRECTION IS INDICATED.

                                       2


        PROPOSAL TO APPROVE THE ADA-ES 2005 DIRECTORS' COMPENSATION PLAN

The Company's 2005 Directors' Compensation Plan (the "2005 Plan") was adopted by
the Board on March 17, 2005 and authorized the issuance of shares of Common
Stock and the grant of options to purchase shares of the Company's Common Stock
to non-management directors, all subject to shareholder approval.

The purpose of the 2005 Plan is to advance the interests of the Company by
providing eligible non-management directors an opportunity to acquire or
increase an equity interest in the Company, which thereby will create a stronger
incentive to expend maximum effort for the growth and success of the Company and
will encourage such eligible individuals to continue to service the Company. The
2005 Plan provides a portion of the annual compensation to non-management
directors of the Company in the form of awards of shares of Common Stock and
vesting of options to purchase Common Stock of the Company for services
performed for the Company. Under the 2005 Plan, the award of stock is limited to
not more than 1,000 shares per individual per year, and the grant of options is
limited to 5,000 per individual in total. The 2005 Plan is subject to
shareholder approval. Options granted under the 2005 Plan may not be exercised,
and shares awarded may not be issued until such shareholder approval has been
obtained, and such options and awards will be null and void if such shareholder
approval is not obtained. The aggregate number of shares of Common Stock
reserved for issuance under the 2005 Plan totals 90,000 shares (50,000 in the
form of stock awards and 40,000 in the form of options), and it is the Company's
expectation that such reserved shares will provide an adequate amount to provide
for the anticipated equity compensation portion of non-management director
compensation through 2014.

On March 17, 2005 the Board approved the future issuance of an additional 50,000
shares of Common Stock and options to purchase an additional 40,000 shares to
non-management directors, all under the 2005 Plan. The exercise price shall be
the market price on the date of grant, the shares of Stock underlying the Option
will vest for exercise at a rate of no more than 1,667 shares per annual period
per individual, and any unvested shares of Stock that are outstanding at the
date the individual is no longer is a Director will be forfeited. Shares may be
issued and options may be granted under the Plan only to non-management
directors of the Company or its subsidiaries. There are currently 7 persons who
are eligible for participation in the Plan.

The Plan is contained in a document entitled "ADA-ES, Inc. 2005 Directors'
Compensation Plan." The Plan, if not terminated earlier by the Board, will
terminate ten years after the date of its adoption. 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 the Company's shareholders. No such amendment may adversely affect
any options previously granted under the Plan without the consent of the
recipient(s). Nevertheless, options granted and shares awarded under the Plan
will be null and void if shareholder approval is not obtained. The Plan is
administered by a committee appointed by the Board, which currently consists of
all Board members.

The Plan is not subject to the provisions of the Employee Retirement Income
Security Act of 1974, as amended, and therefore is not qualified under Section
401(a) of the Internal Revenue Code of 1986, as amended (the "Code").

The Board recommends that Shareholders vote FOR approval of the ADA-ES 2005
Directors' Compensation Plan. Assuming a quorum is present at the Meeting, the
affirmative votes cast must exceed the opposing votes cast for the approval of
the ADA-ES 2005 Directors' Compensation Plan

THE SHARES OF COMMON STOCK REPRESENTED BY PROXIES IN THE ACCOMPANYING FORM WILL
BE VOTED FOR THE APPROVAL OF THE ADA-ES 2005 DIRECTORS' COMPENSATION PLAN UNLESS
A CONTRARY DIRECTION IS INDICATED.

                  Tax Considerations with Respect to the Plans
                  --------------------------------------------

Shares of Common Stock Issued for Services 
------------------------------------------ 
There are immediate tax consequences of the issuance of shares for services
performed for the Company. The fair value of the shares received is taxable as
ordinary income to the recipients and the Company receives a deduction for
compensation expense of a like amount. Shares to be issued to non-management
directors are subject to shareholder approval and such grants will be rescinded
in the event such approval is not obtained.

ISO Grants
----------
Certain options granted to employees under the 2004 Plan are intended to qualify
as incentive stock options under the Company's existing 2003 Stock Option Plan.
For such options, the employee does not recognize ordinary income at option
grant or exercise (although the spread between the option price and the option
stock's fair market value at the time of exercise constitutes an item of
adjustment for alternative minimum tax purposes), and the Company cannot deduct
the related compensation expense. The employee is taxed only upon disposition of

                                       3


the option stock. A qualifying disposition occurs when an employee disposes of
incentive stock option stock after completion of the holding period (after two
years of the employee's receipt of the option or after one year of his receipt
of the stock); other dispositions are generally disqualifying dispositions. The
gain is all capital gain for a qualifying disposition. For a disqualifying
disposition, the employee may recognize ordinary income as well as capital gain.
If stock acquired under an incentive stock option is used to acquire stock in
connection with the exercise of an incentive stock option and the transferred
stock has not met the minimum holding period requirements, ordinary income may
be recognized. For a disqualifying dispositions, the Company will receive a tax
deduction for additional compensation to the extent the exercise price is lower,
if at all, than the market price at the date of exercise.

Non-Qualified Stock Options (NQSO)
----------------------------------
Certain options granted to executive officers and options granted to
non-management directors, which are subject to shareholder approval, are
intended to be NQSOs. A individual receiving a NQSO realizes no income upon its
receipt, because the exercise price at the date of grant was equal to the fair
market value at that date. Instead, the recipient may be taxed upon both the
exercise and disposition of the stock acquired pursuant to a NQSO. Options
granted under the Plan to non-management directors may not, in any case, be
exercised until shareholder approval has been obtained and such options will be
null and void if such shareholder approval is not obtained. The Company will
receive a tax deduction for additional compensation to the extent the exercise
price is lower, if at all, than the market price at the date of exercise.

     1.   Tax Implications Upon NQSO Exercise
 
     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.

     2.   Tax Implications Upon Disposition of the NQSO Shares

     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.

Company's management; (ii) discussed with the Company's independent auditors the
matters required to be discussed by Statement on Auditing Standards No. 61
regarding communication with audit committees (Codification of Statements on
Auditing Standards, AU sec. 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),
and has discussed with the Company's independent accountants the independent
accountants' independence.

Stock Option Plans

During 2003 the Company adopted the 2003 ADA-ES, Inc. Stock Option Plan. One
purpose of the plan was to duplicate the options previously awarded by Earth
Sciences that have been cancelled. Otherwise, the plan is intended to serve to
encourage our key employees, through their individual efforts, to improve our
overall performance and to promote profitability by providing them an
opportunity to participate in the increased value they help create. Options
granted under the plan may be in the form of "incentive stock options" as
defined under section 422 of the Internal Revenue Code of 1986, as amended, or
options that are not incentive stock options. The plan is administered by the
Compensation committee of the Board of Directors. The plan was approved by ESI
as the sole shareholder of ADAES prior to the spin-off distribution of ADA-ES
shares. We reserved 400,000 shares of our common stock for issuance under the
plan. In general, all options granted under the plan will lapse ten years from
the date of grant (five years in the case of a 10% stockholder of our company,

                                       10


our parent or one of our subsidiaries). In general, the exercise price of an
option will be determined by the compensation committee of the board of
directors at the time the option is granted and will not be less than 100% of
the fair market value of a share of our common stock on the date the option is
granted. The compensation committee may provide in the option agreement that an
option may be exercised in whole immediately or is exercisable in increments
through a vesting schedule. During 2004, 75,995 options were granted under the
plan.

During 2004 the Company adopted the 2004 Executive Stock Option Plan (as part of
the ADA-ES 2004 Stock Compensation Plan #2), which did not require shareholder
approval. The plan authorized the grant of up to 200,000 options to purchase
shares of the Company's Common Stock to executive officers of the Company. The
purpose of the plan is to promote the growth and profitability of the Company by
awarding options to purchase Common Stock of the Company for services performed
and to be performed in the future. Options granted under the plan are generally
intended to be non-qualified stock options ("NQSO") for federal income tax
purposes. The plan is administered by the Compensation committee of the Board of
Directors. In each case, the option exercise price is the market price on the
date of the grant. The options are exercisable over a 10-year period based on a
vesting schedule that may be accelerated based on performance of the individual
recipients as determined by the Board of Directors. Options were granted under
the Plan to five executive officers, who are also full-time employees of the
Company. During 2004, 200,000 options were granted under the plan, none of which
were vested at December 31, 2004. In January 2005 the Board of Directors
authorized the vesting of 27,080 options under the plan.

Certain Relationships and Related Transactions.

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

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

Section 16(a) Beneficial Ownership Reporting Compliance

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

Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons, Registrant believes that
during the fiscal year ended December 31, 2004, all filing requirements
applicable to its officers, directors and greater than ten percent beneficial
owners were met.

Code of Ethics

The Company has adopted a Code of Ethics for Senior Financial Officers that is
applicable to our principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions. A copy of our Code of Ethics for Senior Financial Officers is filed
as an exhibit to the Company's annual report on Form 10KSB for 2003 and is
posted on the Company's website at www.adaes.com.

shareholder intends to submit a proposal at the meeting that is not included in

APPENDIX A

                                   ADA-ES INC.
                               BOARD OF DIRECTORS
                             AUDIT COMMITTEE CHARTER


1.   PURPOSE

The primary function of the Audit Committee is to assist the Board of Directors
in fulfilling its oversight responsibilities by reviewing: the financial reports
and other information provided by the Company to any governmental body or the
public; the Company's system of internal controls regarding finance, accounting,
and ethics that management and the Board have established; and the Company's
auditing, accounting and financial reporting processes on a general basis.
Consistent with this function, the Audit Committee should encourage continuous
improvement of and foster adherence to, the Company's policies, procedures and
practices at all levels. The Audit Committee's primary duties and
responsibilities are to:

     o    Serve as an independent and objective party to monitor the Company's
          financial reporting process and internal control system.
     o    Review and appraise the audit efforts of the Company's independent
          accountants.
     o    Provide an open avenue of communication among the independent
          accountants, financial and senior management, and the Board of
          Directors.

2.   MEMBERSHIP

The Audit committee will be comprised of not less than three members of the
Board. They will be selected by the Board, taking into account prior experience
in matters to be considered by the Committee, probable availability at times
required for consideration of such matters, and their individual independence
and objectivity.

All members will be directors free from relationships that, in the opinion of
the Board of Directors, would interfere with the exercise of independent
judgment as a committee member.

The Audit committee will select a chairperson from among its members. The
chairperson will serve for a term of not less then one year and shall have the
responsibility of establishing times of meeting and agenda items for the
Committee.

Officers or employees of the Company or any of its subsidiaries may serve on the
Committee. However, a majority of the Committee will be directors who are not
currently, nor were formerly officers of the Company or any of its subsidiaries.

When considering relationships that might affect independence, including
possible affiliate status, the Board of Directors will give appropriate
consideration, in addition to its Audit Committee policy, to guidelines issued
by the National Association of Securities Dealers (NASD), which were provided to
assist Board of Directors in observing the spirit of the NASD policy on audit
committee requirements.

3.   MEETINGS

The Committee shall meet at least four times annually, or more frequently as
circumstances dictate. As part of its job to foster open communication, the
Committee should meet at least annually with management, and the independent
accountants in separate executive sessions to discuss any matters that the
Committee or each of these groups believe should be discussed privately. In
addition, the Committee or at least its chairperson should participate with the
independent accounts and management quarterly to review the Company's financial
statements.

4.   ACTIONS OF THE COMMITTEE

The Committee's activities will include the following actions:

     o    Oversight of the financial statements and relations with the
          independent accountants.

          1.   Instruct the independent accountants that the Board of Directors
               is the client in its capacity as the shareholders'
               representative.

                                       1


          2.   Expect the independent accountants to meet with the Board of
               Directors at least annually so the Board has a basis on which to
               recommend the independent accountants' appointment to the
               shareholders or to ratify its selection of the independent
               accountants.
          3.   Expect financial management and the independent accountants to
               analyze significant financial report issues and practices on a
               timely basis.
          4.   Expect financial management and the independent accountants to
               discuss with the Audit Committee:
               o    Qualitative judgments about whether current or proposed
                    accounting principles and disclosures are appropriate, not
                    just acceptable.
               o    Aggressiveness or conservatism of accounting principles and
                    financial estimates.
          5.   Expect the independent accountants to provide the Audit Committee
               with:
               o    Independent judgments about the appropriateness of the
                    Company's current or proposed accounting principles and
                    whether current or proposed financial disclosures are clear.
               o    Views on whether the accounting principles chosen by
                    management are conservative, moderate, or aggressive as they
                    relate to income, asset, and liability recognition, and
                    whether these accounting principles are commonly used.
               o    Reasons why accounting principles and disclosure practices
                    used for new transactions or events are appropriate.
               o    Reasons for accepting or questioning significant estimates
                    made by management.
               o    Views on how selected accounting principles and disclosure
                    practices affect shareholder and public attitudes about the
                    Company.
               o    Actions taken on the Board's behalf that require Board
                    notification but not Board approval:
          1.   Review and approve the scope of the Company's audit and that of
               its subsidiaries as recommended by the independent accountants
               and the president.
          2.   Review and approve the scope of the Company's annual profit and

               activities if asked to do so by the Board of Directors.

     o    Matters requiring the Committee's review and study before making a
          recommendation for the Board of Directors' action:

               such as the Financial Accounting Standards Board (FASB), the
               Securities and Exchange Commission (SEC), and the American
               Institute of Certified Public Accountants (AICPA), or by any
               comparable bodies outside the U.S.
          2.   The independent accountants' assessment of the strength and
               weaknesses of the Company's financial staff, systems, controls

     Each Option granted under the Plan shall be exercisable in whole or in part
at any time and from time to time over a period commencing on or after the date
of grant of the Option and ending upon the expiration or termination of the
Option, as the Committee shall determine and set forth in the Option Agreement
relating to such Option, but at no greater rate of vesting than set forth in
Section 8 above. Without limitation of the foregoing, the Committee, subject to
the terms and conditions of the Plan, may in its sole discretion provide that an
Option may not be exercised in whole or in part for any period or periods of
time during which such Option is outstanding as the Committee shall determine
and set forth in the Option Agreement relating to such Option. Any such
limitation on the exercise of an Option contained in any Option Agreement may be
rescinded, modified or waived by the Committee, in its sole discretion, at any
time and from time to time after the date of grant of such Option.
Notwithstanding any other provisions of the Plan, no Option shall be exercisable
in whole or in part prior to the date the Plan is approved by the stockholders
of the Corporation as provided in Section 6.1 hereof.

     11.4. Method of Exercise

     An Option that is exercisable hereunder may be exercised by delivery to the
Corporation on any business day, at its principal office addressed to the
attention of the Committee, of written notice of exercise, which notice shall
specify the number of shares for which the Option is being exercised, and shall
be accompanied by payment in full of the Option Price of the shares for which
the Option is being exercised. Payment of the Option Price for the shares of
Stock purchased pursuant to the exercise of an Option shall be made, as
determined by the Committee and set forth in the Option Agreement pertaining to
an Option by cash or by certified check payable to the order of the Corporation.
Payment in full of the Option Price need not accompany the written notice of
exercise provided the notice directs that the Stock certificate or certificates
for the shares for which the Option is exercised be delivered to a licensed
broker acceptable to the Corporation as the agent for the individual exercising
the Option and, at the time such Stock certificate or certificates are

                                       4


delivered, the broker tenders to the Corporation cash (or cash equivalents
acceptable to the Corporation) equal to the Option Price plus the amount (if
any) of federal and/or other taxes which the Corporation may, in its judgment,
be required to withhold with respect to the exercise of the Option. An attempt
to exercise any Option granted hereunder other than as set forth above shall be
invalid and of no force and effect. Promptly after the exercise of an Option and
the payment in full of the Option Price of the shares of Stock covered thereby,
the individual exercising the Option shall be entitled to the issuance of a
Stock certificate or certificates evidencing such individual's ownership of such
shares. An individual holding or exercising an Option shall have none of the
rights of a stockholder until the shares of Stock covered thereby are fully paid
and issued to such individual and, except as provided in Section 19 hereof, no
adjustment shall be made for dividends or other rights for which the record date
is prior to the date of such issuance.

12.  TRANSFERABILITY OF OPTIONS

     12.1. Transferability of Options

     Except as provided in Section 12.2, during the lifetime of an Optionee,
only the Optionee (or, in the event of legal incapacity or incompetency, the
Optionee's guardian or legal representative) may exercise an Option. Except as
provided in Section 12.2, no Option shall be assignable or transferable by the
Optionee to whom it is granted, other than by will or the laws of descent and
distribution.

     12.2. Family Transfers.

     Subject to the terms of the applicable Option Agreement, an Optionee may
transfer all or part of an Option to any Family Member; provided that subsequent
transfers of transferred Options are prohibited except those in accordance with
this Section 12.2 or by will or the laws of descent and distribution; and,
provided further, that, except with the consent of the Board or the Committee,
there may be no consideration for any transfer made pursuant to this section.
Following transfer, any such Option shall continue to be subject to the same
terms and conditions as were applicable immediately prior to transfer, provided
that for purposes of Section 12.2 hereof the term "Optionee" shall be deemed to
refer to the transferee. The events of termination of the Service Relationship
of Sections 13 and 14 hereof shall continue to be applied with respect to the
original Optionee, following which the Option shall be exercisable by the
transferee only to the extent, and for the periods, specified in Section 11.3.

13.  TERMINATION OF SERVICE RELATIONSHIP

     Upon the termination of the Service Relationship of an Optionee with the
Corporation, a Subsidiary or an Affiliate, other than by reason of the death or
"permanent and total disability" (within the meaning of Section 22(e)(3) of the
Code) of such Optionee or for Cause, any Option granted to an Optionee pursuant
to the Plan shall continue to be exercisable only to the extent that it was
exercisable immediately before such termination; provided, however, such Option
shall terminate thirty (30) days after the date of such termination of Service
Relationship, unless earlier terminated pursuant to Section 11.1 hereof, and
such Optionee shall have no further right to purchase shares of Stock pursuant
to such Option; and provided further, that the Committee may provide, by
inclusion of appropriate language in any Option Agreement, that an Optionee may
(subject to the general limitations on exercise set forth in Section 11.3
hereof), in the event of termination of the Service Relationship of the Optionee
with the Corporation, a Subsidiary or an Affiliate, exercise an Option, in whole
or in part, at any time subsequent to such termination of Service Relationship
and prior to termination of the Option pursuant to Section 11.1 hereof, either
subject to or without regard to any installment limitation on exercise imposed
pursuant to Section 11.3 hereof, as the Committee, in its sole and absolute
discretion, shall determine and set forth in the Option Agreement. Upon the
termination of the Service Relationship of an Optionee with the Corporation, a
Subsidiary or an Affiliate for Cause, any Option granted to an Optionee pursuant
to the Plan shall terminate and such Optionee shall have no further right to
purchase shares of Stock pursuant to such Option; and provided however, that the
Committee may provide, by inclusion of appropriate language in any Option
Agreement, that an Optionee may (subject to the general limitations on exercise
set forth in Section 11.3 hereof), in the event of termination of the Service
Relationship of the Optionee with the Corporation, a Subsidiary or an Affiliate
for Cause, exercise an Option, in whole or in part, at any time subsequent to
such termination of Service Relationship and prior to termination of the Option
pursuant to Section 11.1 hereof, either subject to or without regard to any
installment limitation on exercise imposed pursuant to Section 11.3 hereof, as
the Committee, in its sole and absolute discretion, shall determine and set
forth in the Option Agreement. Whether a leave of absence or leave on military
or government service shall constitute a termination of Service Relationship for
purposes of the Plan shall be determined by the Committee, which determination
shall be final and conclusive. For purposes of the Plan, including without
limitation this Section 13 and Section 14, unless otherwise provided in an
Option Agreement, a termination of Service Relationship with the Corporation, a
Subsidiary or an Affiliate shall not be deemed to occur if the Optionee
immediately thereafter has a Service Relationship with the Corporation, any
other Subsidiary or any other Affiliate.

                                       5


14.  RIGHTS IN THE EVENT OF DEATH OR DISABILITY

     14.1. Death

     If an Optionee dies while in a Service Relationship with the Corporation, a
Subsidiary or an Affiliate or within the period following the termination of
such Service Relationship during which the Option is exercisable under Section
13 or 14.2 hereof, the executors, administrators, legatees or distributees of
such Optionee's estate shall have the right (subject to the general limitations
on exercise set forth in Section 11.3 hereof), at any time within one year after
the date of such Optionee's death and prior to termination of the Option
pursuant to Section 11.1 hereof, to exercise, in whole or in part, any Option
held by such Optionee at the date of such Optionee's death, whether or not such
Option was exercisable immediately prior to such Optionee's death; provided,
however, that the Committee may provide by inclusion of appropriate language in
any Option Agreement that, in the event of the death of an Optionee, the
executors, administrators, legatees or distributees of such Optionee's estate
may exercise an Option (subject to the general limitations on exercise set forth
in Section 11.3 hereof), in whole or in part, at any time subsequent to such
Optionee's death and prior to termination of the Option pursuant to Section 11.1
hereof, either subject to or without regard to any installment limitation on
exercise imposed pursuant to Section 11.3 hereof, as the Committee, in its sole
and absolute discretion, shall determine and set forth in the Option Agreement.

     14.2. Disability

     If an Optionee terminates a Service Relationship with the Corporation, a
Subsidiary or an Affiliate by reason of the "permanent and total disability"
(within the meaning of Section 22(e)(3) of the Code) of such Optionee, then such
Optionee shall have the right (subject to the general limitations on exercise
set forth in Section 11.3 hereof), at any time within one year after such
termination of Service Relationship and prior to termination of the Option
pursuant to Section 11.1 hereof, to exercise, in whole or in part, any Option
held by such Optionee at the date of such termination of Service Relationship,
whether or not such Option was exercisable immediately prior to such termination
of Service Relationship; provided, however, that the Committee may provide, by
inclusion of appropriate language in any Option Agreement, that an Optionee may
(subject to the general limitations on exercise set forth in Section 11.3
hereof), in the event of the termination of the Service Relationship of the
Optionee with the Corporation or a Subsidiary by reason of the "permanent and
total disability" (within the meaning of Section 22(e)(3) of the Code) of such
Optionee, exercise an Option, in whole or in part, at any time subsequent to
such termination of Service Relationship and prior to termination of the Option
pursuant to Section 11.1 hereof, either subject to or without regard to any
installment limitation on exercise imposed pursuant to Section 11.3 hereof, as
the Committee, in its sole and absolute discretion, shall determine and set
forth in the Option Agreement. Whether a termination of a Service Relationship
is to be considered by reason of "permanent and total disability" for purposes
of the Plan shall be determined by the Committee, which determination shall be
final and conclusive.

15.  USE OF PROCEEDS

     The proceeds received by the Corporation from the sale of Stock pursuant to
Options granted under the Plan shall constitute general funds of the
Corporation.

16.  SECURITIES LAWS

     The Corporation shall not be required to sell or issue any shares of Stock
under any Stock Award or Option if the sale or issuance of such shares would
constitute a violation by the individual receiving the Stock Award or exercising
the Option or by the Corporation of any provisions of any law or regulation of
any governmental authority, including, without limitation, any federal or state
securities laws or regulations. If at any time the Corporation shall determine,
in its discretion, that the listing, registration or qualification of any shares
subject to the Stock Award or the Option upon any securities exchange or under
any state or federal law, or the consent of any government regulatory body, is
necessary or desirable as a condition of, or in connection with, the issuance or
purchase of shares, the Stock Award may not be issued or the Option may not be
exercised in whole or in part unless such listing, registration, qualification,
consent or approval shall have been effected or obtained free of any conditions

                                       6


not acceptable to the Corporation, and any delay caused thereby shall in no way
affect the date of termination of the Option. Specifically in connection with
the Securities Act, upon exercise of any Option or issuance of any Stock Award,
unless a registration statement under the Securities Act is in effect with
respect to the shares of Stock covered by such Option or Stock Award, the
Corporation shall not be required to sell or issue such shares unless the
Corporation has received evidence satisfactory to the Corporation that the
Optionee or Stock Recipient may acquire such shares pursuant to an exemption
from registration under the Securities Act. Any determination in this connection
by the Corporation shall be final and conclusive. The Corporation may, but shall
in no event be obligated to, register any securities covered hereby pursuant to
the Securities Act. The Corporation shall not be obligated to take any
affirmative action in order to cause the exercise of an Option or the issuance
of shares pursuant thereto or pursuant to a Stock Award to comply with any law
or regulation of any governmental authority. As to any jurisdiction that
expressly imposes the requirement that an issuance of a Stock Award or an Option
shall not be exercisable unless and until the shares of Stock covered by such
Stock Award or Option are registered or are subject to an available exemption
from registration, the Stock Award or exercise of such Option (under
circumstances in which the laws of such jurisdiction apply) shall be deemed
conditioned upon the effectiveness of such registration or the availability of
such an exemption.

17.  EXCHANGE ACT: RULE 16b-3

     17.1. General

     The Plan is intended to comply with Rule 16b-3 ("Rule 16b-3") (and any
successor thereto) under the Exchange Act. Any provision inconsistent with Rule
16b-3 shall, to the extent permitted by law and determined to be advisable by
the Committee (constituted in accordance with Section 17.2 hereof), be
inoperative and void.

     17.2. Compensation Committee

     The Committee appointed in accordance with Section 3.1 hereof shall consist
of not fewer than two members of the Board each of whom shall qualify (at the
time of appointment to the Committee and during all periods of service on the
Committee) in all respects as a "non-employee director" as defined in Rule
16b-3.

     17.3. Restriction on Transfer of Stock

     No Stock Recipient or Optionee who is considered an "insider" of the
Corporation subject to Section 16 of the Exchange Act shall be permitted to sell
Stock (which such "insider" had received in a Stock Award or upon exercise of an
Option) during the three months immediately following such Stock Award or the
grant of such Option.

18.  AMENDMENT AND TERMINATION

     The Board may, at any time and from time to time, suspend or terminate the
Plan and make such changes in or additions to the Plan as it may deem proper,
provided that, if and to the extent provided by applicable law or regulation, no
such suspension or termination of, change in or addition to the Plan shall be
made unless such suspension or termination of, or change in or addition to the
Plan is authorized by the Company's stockholders. Except as permitted under
Section 19 hereof, no suspension or termination of the Plan or any change in or
addition to the Plan shall, without the consent of any Optionee who is adversely
affected thereby, alter any Options previously granted to the Optionee pursuant
to the Plan.

19.  EFFECT OF CHANGES IN CAPITALIZATION

     19.1. Changes in Stock

     If the number of outstanding shares of Stock is increased or decreased or
changed into or exchanged for a different number or kind of shares or other
securities of the Corporation by reason of any recapitalization,
reclassification, stock split-up, combination of shares, exchange of shares,
stock dividend or other distribution payable in capital stock, or other increase
or decrease in such shares effected without receipt of consideration by the
Corporation, occurring after the effective date of the Plan, a proportionate and
appropriate adjustment shall be made by the Corporation in the number and kind
of shares issuable and exercisable under the Plan and for which Options are

                                       7


outstanding, so that the proportionate interest of the Optionee immediately
following such event shall, to the extent practicable, be the same as
immediately prior to such event. Any such adjustment in outstanding Options
shall not change the aggregate Option Price payable with respect to shares
subject to the unexercised portion of the Option outstanding but shall include a
corresponding proportionate adjustment in the Option Price per share.
Notwithstanding the foregoing, in the event of a spin-off that results in no
change in the number of outstanding shares of Stock of the Corporation, the
Corporation may, in such manner as the Corporation deems appropriate, adjust (i)
the number and kind of shares of Stock subject to outstanding Options and/or
(ii) the exercise price of outstanding Options.

     19.2. Reorganization With Corporation Surviving

     Subject to Section 19.3 hereof, if the Corporation shall be the surviving
entity in any reorganization, merger or consolidation of the Corporation with
one or more other entities, any Option theretofore granted pursuant to the Plan
shall pertain to and apply to the securities to which a holder of the number of
shares of Stock subject to such Option would have been entitled immediately
following such reorganization, merger or consolidation, with a corresponding
proportionate adjustment of the Option Price per share so that the aggregate
Option Price thereafter shall be the same as the aggregate Option Price of the
shares remaining subject to the Option immediately prior to such reorganization,
merger or consolidation.

     19.3. Other Reorganizations; Sale of Assets or Stock

     Upon the dissolution or liquidation of the Corporation, or upon a merger,
consolidation or reorganization of the Corporation with one or more other
entities in which the Corporation is not the surviving entity, or upon a sale of
substantially all of the assets of the Corporation to another person or entity,
or upon any transaction (including, without limitation, a merger or
reorganization in which the Corporation is the surviving entity) approved by the
Board that results in any person or entity (other than persons who are holders
of stock of the Corporation at the time the Plan is approved by the Stockholders
and other than an Affiliate) owning 80 percent or more of the combined voting
power of all classes of stock of the Corporation, the Plan and all Options
outstanding hereunder shall terminate, except to the extent provision is made in
connection with such transaction for the continuation of the Plan and/or the
assumption of the Options theretofore granted, or for the substitution for such
Options of new options covering the stock of a successor entity, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kinds of
shares and exercise prices, in which event the Plan and Options theretofore
granted shall continue in the manner and under the terms so provided. In the
event of any such termination of the Plan, each Optionee shall have the right
(subject to the general limitations on exercise set forth in Section 11.3 hereof
and except as otherwise specifically provided in the Option Agreement relating
to such Option), immediately prior to the occurrence of such termination and
during such period occurring prior to such termination as the Committee in its
sole discretion shall designate, to exercise such Option in whole or in part,
whether or not such Option was otherwise exercisable at the time such
termination occurs, but subject to any additional provisions that the Committee
may, in its sole discretion, include in any Option Agreement. The Committee
shall send written notice of an event that will result in such a termination to
all Optionees not later than the time at which the Corporation gives notice
thereof to its stockholders.

     19.4. Adjustments

     Adjustments under this Section 19 relating to stock or securities of the
Corporation shall be made by the Committee, whose determination in that respect
shall be final and conclusive. No fractional shares of Stock or units of other
securities shall be issued pursuant to any such adjustment, and any fractions
resulting from any such adjustment shall be eliminated in each case by rounding
downward to the nearest whole share or unit.

     19.5. No Limitations on Corporation

     The grant of an Option pursuant to the Plan shall not affect or limit in
any way the right or power of the Corporation to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.

20.  WITHHOLDING

     The Corporation or a Subsidiary may be obligated to withhold federal and
local income taxes and Social Security taxes to the extent that an Optionee or
Stock Recipient realizes ordinary income in connection with a Stock Award or the
exercise of an Option. The Corporation or a Subsidiary may withhold amounts
needed to cover such taxes from payments otherwise due and owing to a Stock
Recipient or an Optionee, and upon demand the Stock Recipient or Optionee will
promptly pay to the Corporation or a Subsidiary having such obligation any
additional amounts as may be necessary to satisfy such withholding tax
obligation. Such payment shall be made in cash or cash equivalents.

                                       8


21.  DISCLAIMER OF RIGHTS

     No provision in the Plan or in any Option granted or Option Agreement
entered into pursuant to the Plan shall be construed to confer upon any
individual the right to remain in the employ of the Corporation, any Subsidiary
or any Affiliate, or to interfere in any way with the right and authority of the
Corporation, any Subsidiary or any Affiliate either to increase or decrease the
compensation of any individual at any time, or to terminate any employment or
other relationship between any individual and the Corporation, any Subsidiary or
any Affiliate. The obligation of the Corporation to pay any benefits pursuant to
the Plan shall be interpreted as a contractual obligation to pay only those
amounts described herein, in the manner and under the conditions prescribed
herein. The Plan shall in no way be interpreted to require the Corporation to
transfer any amounts to a third party trustee or otherwise hold any amounts in
trust or escrow for payment to any participant or beneficiary under the terms of
the Plan.

22.  NONEXCLUSIVITY

     Neither the adoption of the Plan nor the submission of the Plan to the
stockholders of the Corporation for approval shall be construed as creating any
limitations upon the right and authority of the Board to adopt such other
incentive compensation arrangements (which arrangements may be applicable either
generally to a class or classes of individuals or specifically to a particular
individual or individuals) as the Board in its discretion determines desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan.

23.  GOVERNING LAW

     This Plan and all Options to be granted hereunder shall be governed by the
laws of the State of Colorado (but not including the choice of law rules
thereof).

     IN WITNESS WHEREOF, the Corporation has caused its duly authorized officer
to execute this Plan as of the 17th day of March, 2005 to evidence its adoption
of this Plan.

     On November 4, 2004, the Board of Directors, after due consideration of the
service being provided by each outside director and its previous deliberations
wherein it determined that an annual retainer fee and option was appropriate,
which amount is to be paid in stock. Subject to shareholder approval, the Board
approved the issuance of 603 shares of the Company's common stock to each
non-management director, for a total of 4,221 shares for service on the Board
from October 1, 2003 through September 30, 2004. The Board also approved,
subject to shareholder approval, the grant of options to acquire 5,000 shares of
the Company's common stock to each non-management director, for a total of
35,000 shares, at an exercise price of $13.80, the closing price of the stock on
November 3, 2004. The options, if approved, will be exercisable over a period of
five years and will vest over a three- year period, one-third each year for
continued service on the Board. If such service is terminated, the non-vested
portion of the option will be forfeited. Options and shares were granted as
follows:

ARTICLE IV

Miscellaneous

4.1  Adjustment in Number of Shares.
     In the event of any change in the number of outstanding shares of Common
Stock by reason of any stock split, stock dividend, or other capital
transaction, the Board of Directors shall determine, in its absolute discretion,
whether such change equitably requires an adjustment in the aggregate number of
shares of Common Stock which are the subject of an Award, but which have not yet
been issued. If the Board of Directors determines that an adjustment is
required, it shall make such adjustments as it deems appropriate. The Board of
Directors shall not, however, award any fractional shares as a result of any
adjustment made under this Section 4.1.

4.2  Non-Alienation of Benefits.
     No Award or other right or benefit under this Plan shall be subject to
anticipation, alienation, sale, assignment, pledge, encumbrance, or charge, and
any attempt to anticipate, alienate, sell, assign, pledge, encumber or charge
the same shall be void. Except with respect to any indebtedness owed by the
Participant to the Corporation, no Award or other right or benefit hereunder
shall in any manner be liable for or subject to the debts, contracts,
liabilities or torts of any Participant. If any Participant hereunder should
become bankrupt or attempt to anticipate, alienate, sell, assign, pledge,
encumber or charge any Award, right or benefit hereunder, then such Award, right
or benefit shall, in the discretion of the Board of Directors, cease and, in
such event, the Corporation may hold or apply the same or any part thereof for
the benefit of the Participant, his or her spouse, children or other dependents,
or any of them, in such manner and in such proportion as the Board of Directors
may deem appropriate.

4.3  Effect of Plan.
     Neither the establishment of this Plan, the granting of any Award, nor the
issuance of any shares of Common Stock thereunder, shall be construed as giving
any employee, Participant, or any other person, any legal right, except as
expressly provided herein, against the Corporation, its Subsidiaries,
shareholders, directors or officers, or the Board of Directors. Nothing
contained in this Plan shall be construed as a contract of employment between
the Corporation (or its Subsidiaries) and any employee or Participant, as a
right of any employee or Participant to be continued in the employ of the
Corporation (or its Subsidiaries), or as a limitation on the right of the
Corporation (or its Subsidiaries) to employ, discipline or discharge any
employee or Participant. No Participant shall acquire any rights as a
shareholder of the Corporation except to the extent that shares of Common Stock
have been issued to him. The rights of any Participant shall be limited to the
right to receive shares of Common Stock, if and when such shares become issuable
under the terms and conditions of this Plan.

                                       3


4.4  Withholding of Taxes.
     The Corporation shall have the right to deduct from any salary or bonuses
payable to any Participant any and all income or payroll taxes required by law
to be withheld from the compensation, whether in cash or shares of Common Stock,
payable to such Participant.


ARTICLE V

Continuation and Amendment of Plan
5.1  Discontinuance of Plan.
     The continuation of this plan is not assumed as a contractual obligation of
the Corporation, and the right is reserved to the Corporation, by action of its
Board of Directors, to discontinue the Plan at any time. If the Plan shall be
discontinued, no additional Awards shall be made under the Plan after the date
of discontinuance, but the Plan shall continue to be operated in accordance with
its terms, as they may hereafter be amended, with respect to any Awards made
prior to the date of discontinuance.

5.2  Amendment.
     The Corporation, by action of its Board of Directors, shall have the right
at any time, whether before or after discontinuance of the Plan, to amend all or
any of the provisions of the Plan in any manner. Any such amendment may prohibit
or postpone the issuance of any shares of Common Stock even though such shares
may have become issuable after the effective date of the amendment pursuant to
any Award granted before the effective date of the amendment.


ARTICLE VI

Acceptance
6.1  Acceptance of Plan.
     By accepting any Award, a Participant shall be deemed to have accepted all
the terms and conditions of this Plan.

6.2  Transfer Restrictions.
     Each Participant upon receiving any shares of Common Stock shall represent
in writing to the Corporation that, if such is the case, the Common Stock so
acquired has not been registered under the Securities Act of 1933 or any state
"Blue Sky" or securities law, that such Common Stock is not freely transferable
and that such Common Stock cannot be offered, sold or transferred in whole or in
part except in compliance with such laws. Such Participant shall also represent
in writing that he is acquiring such Common Stock for his own account, without
any intention to make an unregistered distribution thereof within the meaning of
the Securities Act of 1933 and that any certificate representing such Common
Stock shall bear an appropriate legend to such effect and the transfer agent for
the Common Stock shall be instructed to enter suitable "stop-transfer" notations
in its records to reflect the foregoing.

Board, which shall have the full power and authority to take all actions and to
make all determinations required or provided for under the Plan or any Option
granted or Option Agreement entered into hereunder and all such other actions
and determinations not inconsistent with the specific terms and provisions of
the Plan deemed by the Committee to be necessary or appropriate to the
administration of the Plan or any Option granted or Option Agreement entered

provision of the Plan or of any Option granted or Option Agreement entered into
hereunder shall be final and conclusive.

3.2. No Liability

          No member of the Board or of the Committee shall be liable for any

determination, in good faith with respect to the Plan or any Option granted or

6.   EFFECTIVE DATE AND TERM

6.1. Effective Date

          The Plan shall become effective as of August 23, 2004, the date of
adoption by the Board.

date 10 years after the effective date.

7.   GRANT OF OPTIONS

          Subject to the terms and conditions of the Plan, the Committee may, at
any time and from time to time prior to the date of termination of the Plan,
grant to such eligible individuals as the Committee may determine Options to
purchase such number of shares of Stock on such terms and conditions as the
Committee may determine. Without limiting the foregoing, the Committee may at
any time, with the consent of the Optionee, amend the terms of outstanding
Options or issue new Options in exchange for the surrender and cancellation of
outstanding Options. The date on which the Committee approves the grant of an
Option (or such later date as is specified by the Committee) shall be considered
the date on which such Option is granted. The maximum number of shares of Stock
subject to Options that can be awarded under the Plan to any person is 60,000
shares, which number of shares is subject to adjustment as provided in Section
19 hereof.


8.   OPTION AGREEMENTS

agreements to be executed by the Corporation and the Optionee, in such form or
forms as the Committee shall from time to time determine. Option Agreements
covering Options granted from time to time or at the same time need not contain
similar provisions; provided, however, that all such Option Agreements shall
comply with all terms of the Plan.

                                       4


9.   OPTION PRICE

          The purchase price of each share of Stock subject to an Option shall
be fixed by the Committee and stated in each Option Agreement. The Option Price
shall be not less than the greater of par value or 100 percent of the fair
market value of a share of the Stock covered by the Option on the date the
Option is granted (as determined in good faith by the Committee.

10.  TERM AND EXERCISE OF OPTIONS

10.1. Term

          Each Option granted under the Plan shall terminate and all rights to
purchase shares thereunder shall cease upon the expiration of 10 years from the
date such Option is granted, or on such date prior thereto as may be fixed by
the Committee and stated in the Option Agreement relating to such Option.

10.2. Exercise by Optionee

          Only the Optionee receiving an Option or a transferee of an Option
pursuant to Section 11 (or, in the event of the Optionee's legal incapacity or
incompetency, the Optionee's guardian or legal representative, and in the case
of the Optionee's death, the Optionee's estate) may exercise the Option.

10.3. Option Period and Limitations on Exercise

          Each Option granted under the Plan shall be exercisable in whole or in
part at any time and from time to time over a period commencing on or after the
date of grant of the Option and ending upon the expiration or termination of the
Option, as the Committee shall determine and set forth in the Option Agreement
relating to such Option. Without limitation of the foregoing, the Committee,
subject to the terms and conditions of the Plan, may in its sole discretion
provide that an Option may not be exercised in whole or in part for any period
or periods of time during which such Option is outstanding as the Committee
shall determine and set forth in the Option Agreement relating to such Option.
Any such limitation on the exercise of an Option contained in any Option
Agreement may be rescinded, modified or waived by the Committee, in its sole
discretion, at any time and from time to time after the date of grant of such
Option.

10.4. Method of Exercise

          An Option that is exercisable hereunder may be exercised by delivery
to the Corporation on any business day, at its principal office addressed to the
attention of the Committee, of written notice of exercise, which notice shall
specify the number of shares for which the Option is being exercised, and shall
be accompanied by payment in full of the Option Price of the shares for which
the Option is being exercised. Payment of the Option Price for the shares of
Stock purchased pursuant to the exercise of an Option shall be made, as
determined by the Committee and set forth in the Option Agreement pertaining to
an Option, (a) in cash or by certified check payable to the order of the
Corporation; (b) through the tender to the Corporation of shares of Stock which,
if acquired from the Company, have been owned by the Optionee no less than six
(6) months and which shares shall be valued, for purposes of determining the
extent to which the Option Price has been paid thereby, at their Fair Market
Value on the date of exercise; (c) to the extent permitted by applicable law and
under the terms of the Option Agreement with respect to such Option, by causing
the Corporation to withhold shares of Stock otherwise issuable pursuant to the
exercise of an Option equal in value to the Option Price or portion thereof to
be satisfied pursuant to this clause (c); or (d) by a combination of the methods
described in Sections 10.4(a), 10.4(b) and 10.4(c) hereof; provided, however,
that the Committee may in its discretion impose and set forth in the Option
Agreement pertaining to an Option such limitations or prohibitions on the use of
shares of Stock to exercise Options as it deems appropriate. Payment in full of
the Option Price need not accompany the written notice of exercise provided the
notice directs that the Stock certificate or certificates for the shares for
which the Option is exercised be delivered to a licensed broker acceptable to
the Corporation as the agent for the individual exercising the Option and, at
the time such Stock certificate or certificates are delivered, the broker
tenders to the Corporation cash (or cash equivalents acceptable to the
Corporation) equal to the Option Price plus the amount (if any) of federal
and/or other taxes which the Corporation may, in its judgment, be required to

                                       5


withhold with respect to the exercise of the Option. An attempt to exercise any
Option granted hereunder other than as set forth above shall be invalid and of
no force and effect. Promptly after the exercise of an Option and the payment in
full of the Option Price of the shares of Stock covered thereby, the individual
exercising the Option shall be entitled to the issuance of a Stock certificate
or certificates evidencing such individual's ownership of such shares. A
separate Stock certificate or certificates shall be issued for any shares
purchased pursuant to the exercise of an Option which is an Incentive Stock
Option, which certificate or certificates shall not include any shares which
were purchased pursuant to the exercise of an Option which is not an Incentive
Stock Option. An individual holding or exercising an Option shall have none of
the rights of a stockholder until the shares of Stock covered thereby are fully
paid and issued to such individual and, except as provided in Section 18 hereof,
no adjustment shall be made for dividends or other rights for which the record
date is prior to the date of such issuance.

10.5. Parachute Limitations

          Notwithstanding any other provision of this Plan or of any other
agreement, contract, or understanding heretofore or hereafter entered into by
the Optionee with the Corporation or any Subsidiary, except an agreement,
contract, or understanding hereafter entered into that expressly modifies or
excludes application of this paragraph (an "Other Agreement"), and
notwithstanding any formal or informal plan or other arrangement heretofore or
hereafter adopted by the Corporation (or any such Subsidiary) for the direct or
indirect provision of compensation to the Optionee (including groups or classes
of participants or beneficiaries of which the Optionee is a member), whether or
not such compensation is deferred, is in cash, or is in the form of a benefit to
or for the Optionee (a "Benefit Arrangement"), if the Optionee is a
"disqualified individual," as defined in Section 280G(c) of the Code, any Option
held by that Optionee and any right to receive any payment or other benefit
under this Plan shall not become exercisable or vested (i) to the extent that
such right to exercise, vesting, payment, or benefit, taking into account all
other rights, payments, or benefits to or for the Optionee under this Plan, all
Other Agreements, and all Benefit Arrangements, would cause any payment or
benefit to the Optionee under this Plan to be considered a "parachute payment"
within the meaning of Section 280G(b)(2) of the Code as then in effect (a
"Parachute Payment") and (ii) if, as a result of receiving a Parachute Payment,
the aggregate after-tax amounts received by the Optionee from the Corporation
under this Plan, all Other Agreements, and all Benefit Arrangements would be
less than the maximum after-tax amount that could be received by Optionee
without causing any such payment or benefit to be considered a Parachute
Payment. In the event that the receipt of any such right to exercise, vesting,
payment, or benefit under this Plan, in conjunction with all other rights,
payments, or benefits to or for the Optionee under any Other Agreement or any
Benefit Arrangement would cause the Optionee to be considered to have received a
Parachute Payment under this Plan that would have the effect of decreasing the
after- tax amount received by the Optionee as described in clause (ii) of the
preceding sentence, then the Optionee shall have the right, in the Optionee's
sole discretion, to designate those rights, payments, or benefits under this
Plan, any Other Agreements, and any Benefit Arrangements that should be reduced
or eliminated so as to avoid having the payment or benefit to the Optionee under
this Plan be deemed to be a Parachute Payment.

                                       6


11.  TRANSFERABILITY OF OPTIONS

11.1. Transferability of Options

          Except as provided in Section 11.2, during the lifetime of an
Optionee, only the Optionee (or, in the event of legal incapacity or
incompetency, the Optionee's guardian or legal representative) may exercise an
Option. Except as provided in Section 11.2, no Option shall be assignable or
transferable by the Optionee to whom it is granted, other than by will or the
laws of descent and distribution.

11.2. Family Transfers.

          Subject to the terms of the applicable Option Agreement, an Optionee
may transfer all or part of an Option to any Family Member; provided that
subsequent transfers of transferred Options are prohibited except those in
accordance with this Section 11.2 or by will or the laws of descent and
distribution; and, provided further, that, except with the consent of the Board
or the Committee, there may be no consideration for any transfer made pursuant
to this section. Following transfer, any such Option shall continue to be
subject to the same terms and conditions as were applicable immediately prior to
transfer, provided that for purposes of Section 11.2 hereof the term "Optionee"
shall be deemed to refer to the transferee. The events of termination of the
Service Relationship of Sections 12 and 13 hereof shall continue to be applied
with respect to the original Optionee, following which the Option shall be
exercisable by the transferee only to the extent, and for the periods, specified
in Section 10.3.

                                       7


12.  TERMINATION OF SERVICE RELATIONSHIP

          Upon the termination of the Service Relationship of an Optionee with
the Corporation, a Subsidiary or an Affiliate, other than by reason of the death
or "permanent and total disability" (within the meaning of Section 21(e)(3) of
the Code) of such Optionee or for Cause, any Option granted to an Optionee
pursuant to the Plan shall continue to be exercisable only to the extent that it
was exercisable immediately before such termination; provided, however, such
Option shall terminate thirty (30) days after the date of such termination of
Service Relationship, unless earlier terminated pursuant to Section 10.1 hereof,
and such Optionee shall have no further right to purchase shares of Stock
pursuant to such Option; and provided further, that the Committee may provide,
by inclusion of appropriate language in any Option Agreement, that an Optionee
may (subject to the general limitations on exercise set forth in Section 10.3
hereof), in the event of termination of the Service Relationship of the Optionee
with the Corporation, a Subsidiary or an Affiliate, exercise an Option, in whole
or in part, at any time subsequent to such termination of Service Relationship
and prior to termination of the Option pursuant to Section 10.1 hereof, either
subject to or without regard to any installment limitation on exercise imposed
pursuant to Section 10.3 hereof, as the Committee, in its sole and absolute
discretion, shall determine and set forth in the Option Agreement. Upon the
termination of the Service Relationship of an Optionee with the Corporation, a
Subsidiary or an Affiliate for Cause, any Option granted to an Optionee pursuant
to the Plan shall terminate and such Optionee shall have no further right to
purchase shares of Stock pursuant to such Option; and provided however, that the
Committee may provide, by inclusion of appropriate language in any Option
Agreement, that an Optionee may (subject to the general limitations on exercise
set forth in Section 10.3 hereof), in the event of termination of the Service
Relationship of the Optionee with the Corporation, a Subsidiary or an Affiliate
for Cause, exercise an Option, in whole or in part, at any time subsequent to
such termination of Service Relationship and prior to termination of the Option
pursuant to Section 10.1 hereof, either subject to or without regard to any
installment limitation on exercise imposed pursuant to Section 10.3 hereof, as
the Committee, in its sole and absolute discretion, shall determine and set
forth in the Option Agreement. Whether a leave of absence or leave on military
or government service shall constitute a termination of Service Relationship for
purposes of the Plan shall be determined by the Committee, which determination
shall be final and conclusive. For purposes of the Plan, including without
limitation this Section 12 and Section 13, unless otherwise provided in an
Option Agreement, a termination of Service Relationship with the Corporation, a
Subsidiary or an Affiliate shall not be deemed to occur if the Optionee
immediately thereafter has a Service Relationship with the Corporation, any
other Subsidiary or any other Affiliate.

13.  RIGHTS IN THE EVENT OF DEATH OR DISABILITY

                                       8


13.1. Death

          If an Optionee dies while in a Service Relationship with the
Corporation, a Subsidiary or an Affiliate or within the period following the
termination of such Service Relationship during which the Option is exercisable
under Section 12 or 13.2 hereof, the executors, administrators, legatees or
distributees of such Optionee's estate shall have the right (subject to the
general limitations on exercise set forth in Section 10.3 hereof), at any time
within one year after the date of such Optionee's death and prior to termination
of the Option pursuant to Section 10.1 hereof, to exercise, in whole or in part,
any Option held by such Optionee at the date of such Optionee's death, whether
or not such Option was exercisable immediately prior to such Optionee's death;
provided, however, that the Committee may provide by inclusion of appropriate
language in any Option Agreement that, in the event of the death of an Optionee,
the executors, administrators, legatees or distributees of such Optionee's
estate may exercise an Option (subject to the general limitations on exercise
set forth in Section 10.3 hereof), in whole or in part, at any time subsequent
to such Optionee's death and prior to termination of the Option pursuant to
Section 10.1 hereof, either subject to or without regard to any installment
limitation on exercise imposed pursuant to Section 10.3 hereof, as the
Committee, in its sole and absolute discretion, shall determine and set forth in
the Option Agreement.

13.2. Disability

          If an Optionee terminates a Service Relationship with the Corporation,
a Subsidiary or an Affiliate by reason of the "permanent and total disability"
(within the meaning of Section 22(e)(3) of the Code) of such Optionee, then such
Optionee shall have the right (subject to the general limitations on exercise
set forth in Section 10.3 hereof), at any time within one year after such
termination of Service Relationship and prior to termination of the Option
pursuant to Section 10.1 hereof, to exercise, in whole or in part, any Option
held by such Optionee at the date of such termination of Service Relationship,
whether or not such Option was exercisable immediately prior to such termination
of Service Relationship; provided, however, that the Committee may provide, by
inclusion of appropriate language in any Option Agreement, that an Optionee may
(subject to the general limitations on exercise set forth in Section 10.3
hereof), in the event of the termination of the Service Relationship of the
Optionee with the Corporation or a Subsidiary by reason of the "permanent and
total disability" (within the meaning of Section 22(e)(3) of the Code) of such
Optionee, exercise an Option, in whole or in part, at any time subsequent to
such termination of Service Relationship and prior to termination of the Option
pursuant to Section 10.1 hereof, either subject to or without regard to any
installment limitation on exercise imposed pursuant to Section 10.3 hereof, as
the Committee, in its sole and absolute discretion, shall determine and set
forth in the Option Agreement. Whether a termination of a Service Relationship
is to be considered by reason of "permanent and total disability" for purposes
of the Plan shall be determined by the Committee, which determination shall be
final and conclusive.

14.  USE OF PROCEEDS

          The proceeds received by the Corporation from the sale of Stock
pursuant to Options granted under the Plan shall constitute general funds of the
Corporation.

                                       9


15.  SECURITIES LAWS

          The Corporation shall not be required to sell or issue any shares of
Stock under any Option if the sale or issuance of such shares would constitute a
violation by the individual exercising the Option or by the Corporation of any
provisions of any law or regulation of any governmental authority, including,
without limitation, any federal or state securities laws or regulations. If at
any time the Corporation shall determine, in its discretion, that the listing,
registration or qualification of any shares subject to the Option upon any
securities exchange or under any state or federal law, or the consent of any
government regulatory body, is necessary or desirable as a condition of, or in
connection with, the issuance or purchase of shares, the Option may not be
exercised in whole or in part unless such listing, registration, qualification,
consent or approval shall have been effected or obtained free of any conditions
not acceptable to the Corporation, and any delay caused thereby shall in no way
affect the date of termination of the Option. Specifically in connection with
the Securities Act, upon exercise of any Option, unless a registration statement
under the Securities Act is in effect with respect to the shares of Stock
covered by such Option, the Corporation shall not be required to sell or issue
such shares unless the Corporation has received evidence satisfactory to the
Corporation that the Optionee may acquire such shares pursuant to an exemption
from registration under the Securities Act. Any determination in this connection
by the Corporation shall be final and conclusive. The Corporation may, but shall
in no event be obligated to, register any securities covered hereby pursuant to
the Securities Act. The Corporation shall not be obligated to take any
affirmative action in order to cause the exercise of an Option or the issuance
of shares pursuant thereto to comply with any law or regulation of any
governmental authority. As to any jurisdiction that expressly imposes the
requirement that an Option shall not be exercisable unless and until the shares
of Stock covered by such Option are registered or are subject to an available
exemption from registration, the exercise of such Option (under circumstances in
which the laws of such jurisdiction apply) shall be deemed conditioned upon the
effectiveness of such registration or the availability of such an exemption.

16.  EXCHANGE ACT: RULE 16b-3

16.1. General

          The Plan is intended to comply with Rule 16b-3 ("Rule 16b-3") (and any
successor thereto) under the Exchange Act. Any provision inconsistent with Rule
16b-3 shall, to the extent permitted by law and determined to be advisable by
the Committee (constituted in accordance with Section 16.2 hereof), be
inoperative and void.

16.2. Compensation Committee

          The Committee appointed in accordance with Section 3.1 hereof shall
consist of not fewer than two members of the Board each of whom shall qualify
(at the time of appointment to the Committee and during all periods of service
on the Committee) in all respects as a "non-employee director" as defined in
Rule 16b-3.

                                       10


16.3. Restriction on Transfer of Stock

          No director, officer or other "insider" of the Corporation subject to
Section 16 of the Exchange Act shall be permitted to sell Stock (which such
"insider" had received upon exercise of an Option) during the six months
immediately following the grant of such Option.

17.  AMENDMENT AND TERMINATION

          The Board may, at any time and from time to time, suspend or terminate
the Plan and make such changes in or additions to the Plan as it may deem
proper, provided that, if and to the extent provided by applicable law or
regulation, no such suspension or termination of, change in or addition to the
Plan shall be made unless such suspension or termination of, or change in or
addition to the Plan is authorized by the Company's stockholders. Except as
permitted under Section 18 hereof, no suspension or termination of the Plan or
any change in or addition to the Plan shall, without the consent of any Optionee
who is adversely affected thereby, alter any Options previously granted to the
Optionee pursuant to the Plan.

18.  EFFECT OF CHANGES IN CAPITALIZATION

18.1. Changes in Stock

          If the number of outstanding shares of Stock is increased or decreased
or changed into or exchanged for a different number or kind of shares or other
securities of the Corporation by reason of any recapitalization,
reclassification, stock split-up, combination of shares, exchange of shares,
stock dividend or other distribution payable in capital stock, or other increase
or decrease in such shares effected without receipt of consideration by the
Corporation, occurring after the effective date of the Plan, a proportionate and
appropriate adjustment shall be made by the Corporation in the number and kind
of shares issuable under the Plan and for which Options are outstanding, so that
the proportionate interest of the Optionee immediately following such event
shall, to the extent practicable, be the same as immediately prior to such
event. Any such adjustment in outstanding Options shall not change the aggregate
Option Price payable with respect to shares subject to the unexercised portion
of the Option outstanding but shall include a corresponding proportionate
adjustment in the Option Price per share. Notwithstanding the foregoing, in the
event of a spin-off that results in no change in the number of outstanding
shares of Stock of the Corporation, the Corporation may, in such manner as the
Corporation deems appropriate, adjust (i) the number and kind of shares of Stock
subject to outstanding Options and/or (ii) the exercise price of outstanding
Options.

                                       11


18.2. Reorganization With Corporation Surviving

          Subject to Section 18.3 hereof, if the Corporation shall be the
surviving entity in any reorganization, merger or consolidation of the
Corporation with one or more other entities, any Option theretofore granted
pursuant to the Plan shall pertain to and apply to the securities to which a
holder of the number of shares of Stock subject to such Option would have been
entitled immediately following such reorganization, merger or consolidation,
with a corresponding proportionate adjustment of the Option Price per share so
that the aggregate Option Price thereafter shall be the same as the aggregate
Option Price of the shares remaining subject to the Option immediately prior to
such reorganization, merger or consolidation.

18.3. Other Reorganizations; Sale of Assets or Stock

          Upon the dissolution or liquidation of the Corporation, or upon a
merger, consolidation or reorganization of the Corporation with one or more
other entities in which the Corporation is not the surviving entity, or upon a
sale of substantially all of the assets of the Corporation to another person or
entity, or upon any transaction (including, without limitation, a merger or
reorganization in which the Corporation is the surviving entity) approved by the
Board that results in any person or entity (other than persons who are holders
of stock of the Corporation at the time the Plan is approved by the Stockholders
and other than an Affiliate) owning 80 percent or more of the combined voting
power of all classes of stock of the Corporation, the Plan and all Options
outstanding hereunder shall terminate, except to the extent provision is made in
connection with such transaction for the continuation of the Plan and/or the
assumption of the Options theretofore granted, or for the substitution for such
Options of new options covering the stock of a successor entity, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kinds of
shares and exercise prices, in which event the Plan and Options theretofore
granted shall continue in the manner and under the terms so provided. In the
event of any such termination of the Plan, each Optionee shall have the right
(subject to the general limitations on exercise set forth in Section 10.3 hereof
and except as otherwise specifically provided in the Option Agreement relating
to such Option), immediately prior to the occurrence of such termination and
during such period occurring prior to such termination as the Committee in its
sole discretion shall designate, to exercise such Option in whole or in part,
whether or not such Option was otherwise exercisable at the time such
termination occurs, but subject to any additional provisions that the Committee
may, in its sole discretion, include in any Option Agreement. The Committee
shall send written notice of an event that will result in such a termination to
all Optionees not later than the time at which the Corporation gives notice
thereof to its stockholders.

18.4. Adjustments

          Adjustments under this Section 18 relating to stock or securities of
the Corporation shall be made by the Committee, whose determination in that
respect shall be final and conclusive. No fractional shares of Stock or units of
other securities shall be issued pursuant to any such adjustment, and any
fractions resulting from any such adjustment shall be eliminated in each case by
rounding downward to the nearest whole share or unit.

                                       12


18.5. No Limitations on Corporation

          The grant of an Option pursuant to the Plan shall not affect or limit
in any way the right or power of the Corporation to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.

19.  WITHHOLDING

          The Corporation or a Subsidiary may be obligated to withhold federal
and local income taxes and Social Security taxes to the extent that an Optionee
realizes ordinary income in connection with the exercise of an Option. The
Corporation or a Subsidiary may withhold amounts needed to cover such taxes from
payments otherwise due and owing to an Optionee, and upon demand the Optionee
will promptly pay to the Corporation or a Subsidiary having such obligation any
additional amounts as may be necessary to satisfy such withholding tax
obligation. Such payment shall be made in cash or cash equivalents.

20.  DISCLAIMER OF RIGHTS

          No provision in the Plan or in any Option granted or Option Agreement
entered into pursuant to the Plan shall be construed to confer upon any
individual the right to remain in the employ of the Corporation, any Subsidiary
or any Affiliate, or to interfere in any way with the right and authority of the
Corporation, any Subsidiary or any Affiliate either to increase or decrease the
compensation of any individual at any time, or to terminate any employment or
other relationship between any individual and the Corporation, any Subsidiary or
any Affiliate. The obligation of the Corporation to pay any benefits pursuant to
the Plan shall be interpreted as a contractual obligation to pay only those
amounts described herein, in the manner and under the conditions prescribed
herein. The Plan shall in no way be interpreted to require the Corporation to
transfer any amounts to a third party trustee or otherwise hold any amounts in
trust or escrow for payment to any participant or beneficiary under the terms of
the Plan.

21.  NONEXCLUSIVITY

          The adoption of the Plan shall not be construed as creating any
limitations upon the right and authority of the Board to adopt such other
incentive compensation arrangements (which arrangements may be applicable either
generally to a class or classes of individuals or specifically to a particular
individual or individuals) as the Board in its discretion determines desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan.

22.  GOVERNING LAWS.

          The laws of the State of Colorado shall govern this Plan and all
Options to be granted hereunder (but not including the choice of law rules
thereof).


          IN WITNESS WHEREOF, the Corporation has caused its duly authorized
officer to execute this Plan as of the 23rd day of August 2004 to evidence its
adoption of this Plan.
