ADA-ES, INC.

PROJECT CROWFOOT INCENTIVE PROGRAM

AS AMENDED AND RESTATED

ON AUGUST
13, 2008 AND OCTOBER 15, 2008

The program described herein (the Program) is established pursuant to
Section 6(e) of ADA-ES, Inc.s (the Company) 2007 Equity Incentive Plan (the Plan).

Establishment of the Program. The Administrator1hereby establishes the Program for the purpose of reserving shares and granting Awards to the grantees named herein (each a Grantee and collectively the
Grantees), to incent and reward them for their work for the Company in reaching certain defined milestones (the Milestones) in connection with the development and putting into commercial operation of the
Companys planned Greenfield activated carbon (AC) manufacturing facility, which the Company refers to as Project Crowfoot.

Shares Reserved. There is hereby reserved within the Plan a total of 172,500 shares of restricted Company common stock (the
Shares) for awards to be issued in accordance with the terms hereof, to Grantees, as follows:

Michael Durham
(57,500Shares);

Mark McKinnies (46,000 Shares);

Jean Bustard (46,000 Shares);

Richard Miller (11,500 Shares); and

Jim Kelly (11,500 Shares);

to be awarded in the discretion
of the Administrator in accordance with the terms hereof, with reverse vesting in accordance with the schedule (Vesting Schedule) set forth herein, and in accordance with the Plan.

Limitation on Awards. Section 6(f) of the Plan sets forth the maximum number of Shares which may underlie Awards made to any individual
grantee under the Plan in any fiscal year (the Individual Annual Plan Maximum). As of the date of the Program, the Individual Annual Plan Maximum is 30,000. During any fiscal year, the Shares awarded to a Grantee under the Program
shall be such as shall assure that all Awards made to any Grantee for that year under the Plan shall not exceed the Individual Annual Plan Maximum, as the same may be amended from time to time in the future.

Awards to Grantees Durham, McKinnies and Bustard. In the sole discretion of the Administrator, and subject to the other requirements set forth
herein, Durham, McKinnies and Bustard (i.e., those Grantees for whom more than 30,000 Shares are reserved under the Program) shall be awarded Shares in the following manner: in FY2008, they shall each be awarded Shares in the amount of the
Individual Annual Plan Maximum less the number of other Shares underlying Awards previously granted to them under the Plan in FY2008; in FY2009 and in any subsequent fiscal year, they shall each receive that number of Shares equal to any remaining
Shares reserved for them under the Program but not more than the Individual Annual Plan Maximum less the number of Shares underlying Awards previously granted to them under the Plan in that fiscal year. In the sole discretion of the Administrator,
Shares shall be awarded annually (at the first regular meeting of the Administrator occurring in a fiscal year) to each Grantee in this manner, subject to the other requirements of the Program, until all Shares reserved under the Program have been
awarded to such Grantees.



|1 | The terms Administrator, Awards, Grantees and Shares shall each have the
meaning given to them in the Plan.

## indicates portions of the exhibit that
have been omitted pursuant to a request for confidential information. The non-public information has been filed with the Commission.



Awards to Grantees Miller and Kelly. In the sole discretion of the Administrator, and subject
to the other requirements set forth herein, Miller and Kelly shall be awarded Shares in an amount up to the number of Shares reserved for them under the Program, but not more than the Individual Annual Plan Maximum less the number of Shares
underlying Awards previously granted to them under the Plan in that fiscal year. In the event the total number of Shares reserved for either Grantee Miller or Kelly cannot be awarded in the first year, Shares shall be awarded in subsequent years, in
the same manner and subject to the same conditions as Awards to be made to Grantees Durham, McKinnies and Bustard.

Conditions to be Met
by Grantee at Time of Award. Each Grantee shall meet all conditions required of a grantee under the Plan at the time of any Award hereunder. In addition, as of such time, each Grantee shall meet the following additional conditions:
(1) Grantee must be meaningfully involved in Project Crowfoot in some capacity; and (2) Grantee must be employed by, or contracted with, the Company or one of its subsidiaries. Notwithstanding the satisfaction of the foregoing conditions,
the Administrator may, in its sole discretion, determine not to make an Award to a Grantee hereunder for any reason, and Grantee shall have no claim against the Company or the Administrator for the Shares that would have otherwise been the subject
of an Award hereunder.

Awards of Shares under the Program are illustrated in the following table:

|2 | For each fiscal year, the number of Shares awarded under the Program to any Grantee may not exceed the Individual Annual
Plan Maximum less the number of shares underlying other Awards previously granted to that Grantee under the Plan during that fiscal year. This Table, which is for illustrative purposes, shows only Awards made through 2010. However, depending on the
number of reserved Shares awarded in prior years, in the discretion of the Administrator, Awards under the Program may be made beyond 2010.
|- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3 | For purposes of this table, it is assumed that the Awards for Grantees Miller and Kelly can be made in their entirety in
FY 2008 without exceeding the Individual Annual Plan Maximum, and will therefore be made in their entirety in FY 2008. In no event however, shall the Award of Shares to either of them hereunder be made in an amount which exceeds the Individual
Annual Plan Maximum, and any Award hereunder shall be reduced in such a manner as to assure compliance with this requirement.

Purchase of Shares by Grantees; Lapse of Companys Repurchase

Crowfoot; and (2) Grantee remains employed by, or contracted with, the Company or one of its subsidiaries. Following the occurrence of a Milestone and as of the next open trading window for the Companys stock in accordance with the

Request to Exchange Vested Shares for Cash. In order to assist the Grantee with minimum statutory withholding obligations that may be owing at the
time of vesting of the Shares, the Company shall have the option, at the request of the Grantee, to repurchase that portion of the Shares (up to 35% of the Shares vesting at the time of a Vesting Event) necessary to satisfy the minimum statutory
withholding obligation of the Grantee, for an amount equal to the Fair Market Value (as such term is defined in the Plan) of the Shares to be so purchased, as of the Vesting Date. The Grantee shall notify the Company in writing as to his or her
request, including therein a statement as to the number of Shares requested to be repurchased by the Company, not later than 10 days after the Vesting Date of each Milestone and the Company will promptly thereafter inform the Grantee whether it
elects to make such repurchase. If and to the extent the Company agrees to repurchase any of such Shares, the Grantee shall promptly transfer the Shares to be so purchased to the Company and the Company will pay the minimum statutory withholding
obligations to the appropriate authorities.

(As Amended and
Restated on August 13, 2008 and October 15, 2008)

Exhibit 1

Milestone Definitions



|1. | Strategic Partner Plus Promote This Milestone shall be deemed satisfied as of the date on which the Company enters into a binding, definitive agreement with a
strategic partner for Project Crowfoot by which the partner commits to contribute no less than $60 million of equity to the project and, as part of that agreement, or in an agreement whereby the partner agrees to purchase an equity interest in the
Company, commits to pay the Company no less than One Million Dollars ($1,000,000) in recognition of the advancement of the project to date (or for any other reason). The total amount of this incentive decreases by 5% of the Shares reserved for the
Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after April 30, 2008, during which this Milestone remains unfulfilled**.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Off-Take Contracts This Milestone shall be deemed satisfied as of the date on which the Company has entered into definitive contracts which provide for the sale of a
total 200 million pounds of AC over a period of no more than ten (10) years, with pricing within the range set forth in the financial model for the project as of the time of Financial Close (as defined in Milestone #3). The total amount of
this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after Financial Close (as defined in Milestone #3), during which this Milestone remains
unfulfilled**.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Financial Close This Milestone shall be deemed satisfied as of the date on which the Company has entered into definitive contracts which provide for the date on which
debt financing sufficient to assure construction of the first facility (including all items necessary to complete the facility and the first AC production line) is irrevocably committed, subject only to customary funding conditions. The total amount
of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after ##, during which this Milestone remains unfulfilled**.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Project Schedule  Plant Start Up This Milestone shall be deemed satisfied as of the date on which the first production line in the facility is placed into
commercial service with an output capacity of no less than ## million pounds of AC per year. The total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each
monthly anniversary after ##, during which this Milestone remains unfulfilled**

## indicates portions of the exhibit that have been omitted pursuant to a request for confidential information. The non-public
information has been filed with the Commission.



|5. | Commercial Production/Profitability  This Milestone shall be deemed satisfied as of the date, which shall be no sooner than one year after Plant Start Up (as defined in
Milestone #4), when for a six month average consecutive period, the plant has produced AC with an output capacity of greater than ## million pounds of AC per year, at a cost that is within 10% of budgeted operating cost per the financial model in
effect as of Financial Close (as defined in Milestone #3). The total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after ## during
which this Milestone remains unfulfilled**.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

With respect to Shares awarded to Executives other than Mr. Miller:

*, ** If a Milestone is unfulfilled as of a particular date resulting in a decrease in the amount of an incentive for a certain Milestone, the number of Shares otherwise
allocated to such Milestone resulting from such decrease shall be reallocated to the next Milestone until the Share cap for such Milestone is reached. Such reallocation shall automatically take place as of the beginning of the day immediately
following the deadline for each Milestone that remains unfulfilled. For example, as of July 1, 2008, the Strategic Partner Plus Promote Milestone had not been fulfilled, resulting in a decrease in the number of Shares reserved for
each Grantee for such Milestone in the amount of 10% total. Accordingly, as of July 1, the Shares would be reallocated as shown on the attached Schedule 1. Once the Share caps for every Milestone are reached, any Shares that would have
otherwise been re-allocated shall be forfeited and permanently restricted from vesting, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter, notwithstanding anything to the contrary in the RSPA or the
Plan.

With respect to Shares awarded to Messrs. Miller and Kelly:



|* | For clarification purposes, the parties acknowledge that the failure to achieve a milestone within twenty (20) months after the initial date specified for the Milestone will
divest the Grantee to all rights to the Shares to have vested for attainment of that Milestone.
|- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|** | If a Milestone is unfulfilled as of a particular date, thereby leading to a forfeiture of the percentage of Shares specified in the Milestone, the Shares representing that
percentage so forfeited shall be permanently restricted from vesting with the Grantee, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter, notwithstanding any contrary provision of the RSPA or the Plan.

ADA-ES INC. 2007 EQUITY INCENTIVE PLAN

PROJECT CROWFOOT INCENTIVE PROGRAM

RESTRICTED STOCK PURCHASE AWARD AGREEMENT

1. Purchase of Shares. ADA-ES INC., a Colorado corporation (the Company), hereby issues and sells to the Grantee (the Grantee) named in the Notice of Restricted Stock
Purchase Award (the Notice), the Total Number of Shares of Common Stock Awarded set forth in the Notice (the Shares) for a Purchase Price per Share set forth in the Notice (the Total Purchase
Price), subject to the Notice, this Restricted Stock Purchase Award Agreement (the Agreement), the terms and provisions of the Companys 2007 Equity Incentive Plan, as amended from time to time (the
Plan) and the terms and provisions of the Project Crowfoot Incentive Program, as amended and restated on August 13, 2008 and October 15, 2008 (the Program), which are incorporated herein by reference.
Payment for the Shares in the amount of the Total Purchase Price set forth in the Notice shall be made to the Company upon execution of the Notice. Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings
in this Agreement. All Shares sold hereunder will be deemed issued to the Grantee as fully paid and nonassessable shares, and the Grantee will have the right to vote the Shares at meetings of the Companys shareholders. The Company shall pay
any applicable stock transfer taxes imposed upon the issuance of the Shares to the Grantee hereunder.

2. Method of Payment. Payment
of the Total Purchase Price shall be by any of the following, or a combination thereof, at the election of the Grantee; provided, however, that such payment method does not then violate an Applicable Law:

(a) cash; or

(b) check.

3. Transfer Restrictions. The Shares sold to the Grantee hereunder may not be sold, transferred by gift,
pledged, hypothecated, or otherwise transferred or disposed of by the Grantee prior to the date when the Shares become vested pursuant to the Vesting Schedule set forth in the Notice. Any attempt to transfer Restricted Shares in violation of this
Section 3 will be null and void and will be disregarded. Before the Shares fully vest, the Shares will be subject to the Companys Repurchase Rights as set forth in Section 8 below.

4. Escrow of Stock. For purposes of facilitating the enforcement of the provisions of this Agreement, the Grantee agrees, immediately upon
receipt of the certificate(s) for the Restricted Shares, to deliver such certificate(s), together with an Assignment Separate from Certificate in the form attached hereto as Exhibit A, executed in blank by the Grantee and the

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

5. Distributions. Except as set forth in Section 8(e), the Company shall disburse to the Grantee all dividends and other distributions paid
or made in cash with respect to the Shares and Additional Securities (whether vested or not), less any applicable withholding obligations.

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

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

7. Additional Securities. Any securities received as the result of ownership of the Restricted Shares (the Additional Securities), including, but not by way of limitation, warrants, options
and securities received as a stock dividend or stock split, or as a result of a recapitalization or reorganization or other similar change in the Companys capital structure, shall be retained in escrow in the same manner and subject to the
same conditions and restrictions as the Restricted Shares with respect to which they were issued, including, without limitation, the Vesting Schedule set forth in the Notice and the Companys Repurchase Rights. The Grantee shall be entitled to
direct the Company to exercise any warrant, option or other right received as Additional Securities upon supplying the funds necessary to do so, in which event the securities so purchased shall constitute Additional Securities, but the Grantee may
not direct the Company to sell any such warrant, option or right. If Additional Securities consist of a convertible security, the Grantee may exercise any conversion right, and any securities so acquired shall constitute Additional Securities.
Appropriate adjustments to reflect the distribution of Additional Securities shall be made to the price per share to be paid upon the exercise of the Repurchase Right in order to reflect the effect of any such transaction upon the Companys
capital structure. In the event of any change in certificates evidencing the Shares or the Additional Securities by reason of any recapitalization, reorganization or other transaction that results in the creation of Additional Securities, the escrow
holder is authorized to deliver to the issuer the certificates evidencing the Shares or the Additional Securities in exchange for the certificates of the replacement securities.

8. Companys Repurchase Rights.

(a) Grant of Repurchase Rights. The Company is hereby granted the right to repurchase all or any portion of the Shares that are Restricted Shares and any Additional Securities (the Repurchase
Right) exercisable at any time during the period commencing on the date the Grantees Continuous Service terminates for any reason, with or without cause (including death or disability) (the Termination Date) and
ending ninety (90) days after the first date on which the Repurchase Right may be exercised without incurring an accounting expense with respect to such exercise (the Share Repurchase Period). Notwithstanding the foregoing,
if a Milestone under the Program is unfulfilled as of a particular date and the Shares attributable to such Milestone are not reallocated to another Milestone, thereby leading to a forfeiture of Shares, such forfeited Shares shall be permanently
restricted from vesting with the Grantee, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter, notwithstanding any contrary provision of this Agreement or the Plan.

November 7, 2008

## indicates portions of the exhibit that have been omitted pursuant to a request for confidential information. The non-public
information has been filed with the Commission.



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

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

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

(e) Corporate Transaction/Change in Control. Immediately prior to the consummation of a Corporate Transaction described in
Section 2(q)(i), (ii) or (iii) of the Plan or a Change in Control, the Repurchase Right as to all unvested Shares and any Additional Securities shall automatically lapse in its entirety, except to the extent this Agreement is Assumed,
in which case the Repurchase Right shall apply to the new capital stock or other property received in exchange for the unvested Shares and Additional Securities in consummation of the Corporate Transaction or Change in Control, but only to the
extent the unvested Shares and Additional Securities are at the time covered by such right. The Repurchase Right as to Restricted Shares and Additional Securities shall apply to the new capital stock or other property (including cash paid other than
as a regular cash dividend) received in exchange for the Shares and Additional Securities in consummation of a Corporate Transaction and such stock or property shall be deemed Additional Securities for purposes of this Agreement, but only to the
extent the Shares and Additional Securities are at the time covered by such Repurchase Right. Appropriate adjustments shall be made to the price per share payable upon exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction.

9. Stop-Transfer Notices. In order to ensure compliance with the restrictions on transfer set

effect in its own records.

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

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

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE ACT) AND MAY

12. Lock-Up Agreement.

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

(b) No Amendment Without Consent of Underwriter. During the period from identification as a Lead
Underwriter in connection with any public offering of the Companys Common Stock until the earlier of (i) the expiration of the lock-up period specified in Section 12(a) in connection with such offering or (ii) the abandonment of
such offering by the Company and the Lead Underwriter, the provisions of this Section 12 may not be amended or waived except with the consent of the Lead Underwriter.

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

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

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

the provisions of this Agreement and those of the Plan, the provisions of the Plan shall control.

determines that the Award may be or become subject to Code Section 409A, the Administrator may adopt such amendments to the Plan and/or this Agreement or adopt other policies and procedures (including amendments, policies and procedures with
retroactive effect), or take any other actions, that the Administrator determines are necessary or appropriate to (a) exempt the Plan and/or the Award from the application of Code Section 409A and/or preserve the intended tax treatment of
the benefits provided with respect to this option, or (b) comply with the requirements of Code Section 409A.

18.

both oral and written, between the parties concerning the subject matter of this Agreement. The Company may, in its sole discretion, decide to deliver any documents related to Units awarded under the Plan or future Units that may be awarded under

subject matter hereof, and may not be modified adversely to the Grantees interest except by means of a writing signed by the Company and the Grantee. These agreements are to be construed in accordance with and governed by the internal laws of
the State of Colorado, without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of Colorado to the rights and duties of the parties. Should any
provision of the Notice or this Agreement be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable.

vesting and issuance would be exempt from the registration requirements of the Act.

hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States mail by certified mail (if the parties are within the United States) or upon deposit for delivery by an

|DATE :     |  | ___________________________

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

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

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

(c) Grantee is familiar with the provisions of Rule 144 promulgated under the Securities
Act, which, in substance, permit limited public resale of restricted securities acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. The Securities may be
resold in certain limited circumstances subject to the provisions of Rule 144, which requires (i) the resale to occur not less than six months after the later of the date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; (ii) in the case of acquisition of the Securities by a non-affiliate who subsequently holds the Securities less than one year, the availability of certain public information
about the Company; and (iii) in the case of acquisition of the Securities by an affiliate: (A) the resale being made through a broker in an unsolicited brokers transaction or in transactions directly with a market maker
(as said term is defined under the Securities Exchange Act of 1934), (B) the availability of certain public information about the Company, (C) the amount of Securities being sold during any three month period not exceeding the limitations
specified in Rule 144(e), and (D) the timely filing of a Form 144, if applicable. Other restrictions may also apply to sales of the Securities, and Grantee understands that the Securities may not be readily resold, and that delays may occur in
selling the Securities, even if they are eligible for sale under Rule 144.

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

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