NOTICE OF GRANT OF PERFORMANCE SHARE UNIT AWARD AND AWARD AGREEMENT

Effective %%OPTION_DATE%-%, you have been granted a target award of %%TOTAL_SHARES_GRANTED%-% Performance Share Units (“Award”) under the Devon Energy Corporation 2009 Long-Term Incentive Plan. Each Performance Share Unit that vests entitles you to one share of Devon Energy Corporation (the “Company”) Common Stock.

This Award also entitles you to be paid Dividend Equivalents as set forth in the Award Agreement.

By accepting this agreement online, you and the Company agree that this award is granted under and governed by the terms and conditions of the Company’s 2009 Long-Term Incentive Plan and the Award Agreement, both of which are attached and made a part of this document.

WHEREAS, in connection with the Participant’s employment with the Company, the Company desires to award to the Participant %%TOTAL_SHARES_GRANTED%-% Performance Share Units subject to the terms and conditions of this Award Agreement and the Plan; and

WHEREAS, the Performance Share Units granted pursuant to this Award Agreement shall vest based on the attainment and certification of the Performance Goal set forth on Schedule A; and

NOW, THEREFORE, in consideration of the premises and the mutual promises and covenants herein contained, the Participant and the Company agree as follows:

1. The Plan. The Plan, a copy of which is attached hereto, is hereby incorporated by reference herein and made a part hereof for all purposes, and when taken with this Award Agreement shall govern the rights of the Participant and the Company with respect to the Award.

2. Grant of Award. The Company hereby grants to the Participant a target award (the “Award”) of %%TOTAL_SHARES_GRANTED%-% Performance Share Units, on the terms and conditions set forth herein and in the Plan. Each Performance Share Unit that vests entitles the Participant to one share of Common Stock.

3. Terms of Award.

(a) Performance Share Unit Account. The Company shall establish a bookkeeping account on its records for the Participant and shall credit the Participant’s Performance Share Units to the bookkeeping account.

(b) General Vesting Terms. Except as provided in this Section 3, the Participant shall vest in a number of Performance Share Units based on the attainment and certification of the Performance Goal described on Schedule A as of the end of a Performance Period. Any Performance Share Units that do not vest as of the end of a Performance Period shall be forfeited as of the end of the Performance Period. Except as specifically provided below in this Section 3, in the event of a termination of the Participant’s employment prior to the end of a Performance Period, all unvested Performance Share Units will be immediately forfeited.

1

(c) If a Participant’s Date of Termination occurs by reason of disability, Normal Retirement Date, Early Retirement Date, or other special circumstances (as determined by the Committee), and the Committee determines, in its sole and absolute discretion, that the Performance Share Units shall continue to vest following the Participant’s Date of Termination, the Participant shall vest in the maximum number of Performance Share Units in which the Participant could vest, based on the actual level at which the Performance Goal is attained and certified for the Performance Period, as if the Participant remained in the employ of the Company through the end of the Performance Period, provided that, if the Participant is Retirement Eligible, such continued vesting shall be subject to the satisfaction of the conditions in Section 15 (except in the case of the Participant’s disability).

(d) Performance Share Units shall continue to vest and the Participant shall vest in the maximum number of Performance Share Units in which the Participant could vest, based on the actual level at which the Performance Goal is attained and certified for the Performance Period, as if the Participant remained in the employ of the Company through the end of the Performance Period following the Participant’s Date of Termination that occurs under circumstances in which the Participant is entitled to a severance payment from the Company, a Subsidiary, or an Affiliated Entity under (A) the Participant’s employment agreement or severance agreement with the Company due to a termination of the Participant’s employment by the Company without “cause” or by the Participant for “good reason” in accordance with the Participant’s employment agreement or severance agreement or (B) the Devon Energy Corporation Severance Plan, provided that for a severance related termination, the Participant signs and returns to the Company a release of claims against the Company in a form prepared by the Company (the “Release”) and such Release becomes effective. If the Participant fails to sign and return the Release to the Company or revokes the Release prior to the date the Release becomes effective, the Performance Share Units (and Dividend Equivalents) subject to this Award Agreement shall be forfeited.

(e) A Participant shall become fully and immediately vested in the Award at the target level of performance for the Performance Period in the event of (1) the Participant’s death or (2) the occurrence of a Change in Control Event.

(f) Voting Rights and Dividend Equivalents. The Participant shall not have any voting rights with respect to the Performance Share Units. The Participant shall be credited with dividend equivalents (“Dividend Equivalents”) with respect to each outstanding Performance Share Unit to the extent that any dividends or other distributions (in cash or other property) are declared and/or paid with respect to the shares of Common Stock after the commencement of the Performance Period (other than distributions pursuant to a share split, for which an adjustment shall be made as described in Section 4 below). Dividend Equivalents shall be credited to the bookkeeping account established on the records of the Company for the Participant and will vest and be paid in cash to the Participant at the same time, and subject to the same conditions, as are applicable to the underlying Performance Share Units. Accordingly, Dividend Equivalents shall be forfeited to the extent that the Performance Share Units do not vest and are forfeited or cancelled. No interest shall be credited on Dividend Equivalents.

(g) Conversion of Performance Share Units; Delivery of Performance Share Units.

(i) Except in the event of the Participant’s death or the occurrence of a Change in Control Event, the Committee shall, within a reasonably practicable time following the last day of the Performance Period, certify the extent, if any, to which the Performance Goal has been achieved with respect to the Performance Period and the number of Performance Share Units, if any, earned upon attainment of the

2

Performance Goal. Such certification shall be final, conclusive and binding on the Participant, and on all other persons, to the maximum extent permitted by law. Payment in respect of vested Performance Share Units and Dividend Equivalents shall be made promptly following the Committee’s certification of the attainment of the Performance Goal, but in any event, no later than March 15 of the year following the year in which the Performance Period ends.

(ii) In the event of the Participant’s death or the occurrence of a Change in Control Event, payment in respect of earned and vested Performance Share Units shall be made as soon as reasonably practicable thereafter.

(iii) Notwithstanding any provision of this Award Agreement to the contrary, in no event shall the timing of the Participant’s execution of the Compliance Certificate, directly or indirectly, result in the Participant designating the calendar year of payment, and if a payment that is subject to execution of the Compliance Certificate could be made in more than one taxable year, payment shall be made in the later taxable year.

(iv) All payments in respect of earned and vested Performance Share Units shall be made in freely transferable shares of Common Stock. No fractional shares of Common Stock shall be issued pursuant to this Award, and any fractional share resulting from any calculation made in accordance with the terms of this Award Agreement shall be rounded down to the next whole share.

4. Certain Corporate Changes. If any change is made to the Common Stock (whether by reason of merger, consolidation, reorganization, recapitalization, stock dividend, stock split, combination of shares, or exchange of shares or any other change in capital structure made without receipt of consideration), then unless such event or change results in the termination of all the Performance Share Units granted under this Award Agreement, the Committee shall adjust, in an equitable manner and as provided in the Plan, the number and class of shares underlying the Performance Share Units, the maximum number of shares for which the Performance Share Units may vest, and the share price or class of Common Stock for purposes of the Performance Goal, as appropriate, to reflect the effect of such event or change in the Company’s capital structure in such a way as to preserve the value of the Performance Share Units. Any adjustment that occurs under the terms of this Section 4 or the Plan will not change the timing or form of payment with respect to any Performance Share Units except as permitted in accordance with section 409A of the Code.

5. Employment. Nothing in the Plan or in this Award Agreement shall confer upon the Participant any right to continue in the employ of the Company or any of its Subsidiaries or Affiliated Entities, or interfere in any way with the right to terminate the Participant’s employment at any time.

6. Nontransferability of Award. The Participant shall not have the right to sell, assign, transfer, convey, dispose, pledge, hypothecate, burden, encumber or charge any Performance Share Unit or any interest therein in any manner whatsoever.

7. Notices. All notices or other communications relating to the Plan and this Agreement as it relates to the Participant shall be in writing and shall be delivered personally or mailed (U.S. mail) by the Company to the Participant at the then current address as maintained by the Company or such other address as the Participant may advise the Company in writing.

8. Binding Effect and Governing Law. This Award Agreement shall be (i) binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and assigns except as may be limited by the Plan, and (ii) governed and construed under the laws of the State of Delaware.

10. Withholding. The Company and the Participant shall comply with all federal and state laws and regulations respecting the required withholding, deposit and payment of any income, employment or other taxes relating to the Award (including Dividend Equivalents). The Company shall withhold the employer’s minimum statutory withholding based upon minimum statutory withholding rates for federal and state purposes, including payroll taxes, that are applicable to such supplemental taxable income. Any payment of required withholding taxes by the Participant in the form of Common Stock shall not be permitted if it would result in an accounting charge with respect to such shares used to pay such taxes unless otherwise approved by the Committee.

11. Award Subject to Claims of Creditors. The Participant shall not have any interest in any particular assets of the Company, its parent, if applicable, or any Subsidiary or Affiliated Entity by reason of the right to earn an Award (including Dividend Equivalents) under the Plan and this Award Agreement, and the Participant or any other person shall have only the rights of a general unsecured creditor of the Company, its parent, if applicable, or a Subsidiary or Affiliated Entity with respect to any rights under the Plan or this Award Agreement.

12. Compliance with Section 409A. This Award is intended to comply with the applicable requirements of section 409A of the Code and shall be administered in accordance with section 409A of the Code. Notwithstanding anything in this Award Agreement to the contrary, if the Performance Share Units constitute “deferred compensation” under section 409A of the Code and any Performance Share Units become payable pursuant to the Participant’s termination of employment, settlement of the Performance Share Units shall be delayed for a period of six months after the Participant’s termination of employment if the Participant is a “specified employee” as defined under section 409A of the Code and if required pursuant to section 409A of the Code. If settlement of the Performance Share Units is delayed, the Performance Share Units shall be settled within 30 days of the date that is the six-month anniversary of the Participant’s termination of employment. If the Participant dies during the six-month delay, the Performance Share Units shall be settled in accordance with the Participant’s will or under the applicable laws of descent and distribution. Notwithstanding any provision to the contrary herein, distributions made with respect to this Award may only be made in a manner and upon an event permitted by section 409A of the Code, and all payments to be made upon a termination of employment hereunder may only be made upon a “separation from service” as defined under section 409A of the Code. To the extent that any provision of the Award Agreement would cause a conflict with the requirements of section 409A of the Code, or would cause the administration of the Performance Share Units to fail to satisfy the requirements of section 409A of the Code, such provision shall be deemed null and void to the extent permitted by applicable law. In no event shall a Participant, directly or indirectly, designate the calendar year of payment. This Award Agreement may be amended without the consent of the Participant in any respect deemed by the Board of Directors or its delegate to be necessary in order to preserve compliance with section 409A of the Code.

13. Captions. The captions of specific provisions of this Award Agreement are for convenience and reference only, and in no way define, describe, extend or limit the scope of this Award Agreement or the intent of any provision hereof.

14. Counterparts. This Award Agreement may be executed in any number of identical counterparts, each of which shall be deemed an original for all purposes, but all of which taken together shall form one agreement.

15. Conditions to Post-Retirement Vesting.

(a) Notice of and Conditions to Post-Retirement Vesting. If the Participant is Retirement Eligible, the Company shall, within a reasonable period of time prior to the Participant’s Date of Termination, notify the Participant that the Participant has the right, pursuant to this Section 15(a), to continue to vest following the Date of Termination in any unvested Performance Share Units provided that the Participant executes and delivers to the Company the following documentation: (i) a non-disclosure letter agreement, in the form attached as Exhibit A,(a “Non-Disclosure Agreement”), on or before the Date of Termination, and (ii) a compliance certificate, in the form attached as Exhibit B, (a “Compliance Certificate”), indicating the Participant’s full compliance with the Non-Disclosure Agreement, no later than the time(s) required by the Committee.

(b) Consequences of Failure to Satisfy Vesting Conditions.

SCHEDULE A

PERFORMANCE GOALS AND PERFORMANCE PERIOD

1. Performance Period. Fifty percent (50%) of the target Award is subject to a two-year Performance Period that begins [date] and ends [date] (the “20    -20     Performance Period”) and 50% of the target Award is subject to a three-year Performance Period that begins [date] and ends [date] (the “20    -20     Performance Period”). The 20    -20     and 20    -20     Performance Periods may each be individually referred to as a “Performance Period.”

2. Performance Goal. The Performance Goal is based on total shareholder return (“TSR”). TSR shall mean the rate of return stockholders receive through stock price changes and the assumed reinvestment of dividends over the Performance Period. Vesting will be based on the Company’s TSR ranking relative to the TSR ranking of the Peer Companies (identified in Section 3(d) below). At the end of the Performance Period, the TSR for the Company, and for each Peer Company, shall be determined pursuant to the following formula:

The result shall be rounded to the nearest hundredth of one percent (.01%).

(a) The term “Closing Average Share Value” means the average value of the common stock for the 30 trading days ending on the last day of the Performance Period, which shall be calculated as follows: (i) determine the closing price of the common stock on each trading date during 30-day period and (ii) average the amounts so determined for the 30-day period.

(b) The term “Opening Average Share Value” means the average value of the common stock for the 30 trading days preceding the start of the Performance Period, which shall be calculated as follows: (i) determine the closing price of the common stock on each trading date during the 30-day period and (ii) average the amounts so determined for the 30-day period.

(c) “Reinvested Dividends” shall be calculated by multiplying (i) the aggregate number of shares (including fractional shares) that could have been purchased during the Performance Period had each cash dividend paid on a single share during that period been immediately reinvested in additional shares (or fractional shares) at the closing selling price per share on the applicable dividend payment date by (ii) the average daily closing price per share calculated for the entire duration of the Performance Period.

(d) Each of the foregoing amounts shall be equitably adjusted for stock splits, stock dividends, recapitalizations and other similar events affecting the shares in question without the issuer’s receipt of consideration.

1

3. Vesting Schedule. The Performance Share Units will vest based on the Company’s relative TSR ranking in respect of the Performance Period as compared to the TSR ranking of the Peer Companies, in accordance with the following schedule:

(a) The actual number of Performance Share Units that vest for each Performance Period may range from 0% to 200% multiplied by 50% of the target Award, with the actual percentage to be determined on the basis of the percentile level at which the Committee certifies that the Performance Goal has been attained in relation to the corresponding Performance Goal for Peer Companies for the Performance Period; provided however, that the maximum number of Performance Share Units that may become earned and vested during each Performance Period will be calculated as follows: %%TOTAL_SHARES_GRANTED%-% x 50% x 200%. The Committee retains sole discretion to reduce the vesting percentage (and thus the number of Performance Share Units that vest), including reduction to zero, without regard to the performance of the Company’s TSR relative to the TSR of the Peer Companies.

(b) If the Company’s final TSR value is equal to the TSR value of a Peer Company, the Committee shall assign the Company the higher ranking.

(c) In addition to the Company, the Peer Companies are Anadarko Petroleum Corporation, Apache Corporation, Chesapeake Energy Corporation, Chevron Corporation, ConocoPhillips, EnCana Corporation, EOG Resources, Inc., Hess Corporation, Marathon Oil Corporation, Murphy Oil Corporation, Noble Energy, Inc., Occidental Petroleum Corporation, Pioneer Natural Resources Company, and Talisman Energy, Inc.

(d) The Peer Companies will be subject to change as follows:

(i) In the event of a merger, acquisition or business combination transaction of a Peer Company, in which the Peer Company is the surviving entity and remains publicly traded, the surviving entity shall remain a Peer Company. Any entity involved in the transaction that is not the surviving company shall no longer be a Peer Company.

(ii) In the event of a merger, acquisition or business combination transaction of a Peer Company, a “going private” transaction or other event involving a Peer Company or the liquidation of a Peer Company, in each case where the Peer Company is not the surviving entity or is no longer publicly traded, the company shall no longer be a Peer Company.

2

(iii) Notwithstanding the foregoing, in the event of a bankruptcy of a Peer Company where the Peer Company is not publicly traded at the end of the Performance Period, such company shall remain a Peer Company but shall be deemed to have a TSR of negative 100% (-100%).

(iv) If a Peer Company ceases to be a publicly traded company at any time during the Performance Period, such company will be replaced as a Peer Company by a company that has been pre-approved by the Committee as a replacement company, provided that each such replacement company satisfies the requirement to be a Peer Company throughout the Performance Period.

4. General Vesting Terms. Any fractional Performance Share Unit resulting from the vesting of the Performance Share Units in accordance with the Award Agreement shall be rounded down to the nearest whole number. Any portion of the Performance Share Units that does not vest as of the end of the Performance Period shall be forfeited as of the end of the Performance Period.
