Pioneer Energy Services Corp. 2007 Incentive Plan Form of Time-Based Phantom Stock Unit Award Agreement

THIS TIME-BASED PHANTOM STOCK UNIT AGREEMENT (this “Agreement”) is made as of <<Date>>, by and between Pioneer Energy Services Corp. (the “Company”) and <<Name>> (the “Employee”) pursuant to the Pioneer Energy Services Corp. Amended and Restated 2007 Incentive Plan (Effective <<Date>>) (the “Plan”). Capitalized terms are defined in the Plan if not defined herein.

The Compensation Committee of the Board of Directors of the Company (the “Committee”) desires to benefit the Company by increasing motivation on the part of the Employee, who is materially important to the Company, by creating an incentive to remain as an employee of the Company and to work to the very best of the Employee’s abilities.

To further this purpose, the Company desires to make an award (the “Award”) of phantom stock units (the “Phantom Stock Units”) to the Employee under the terms of the Plan. The grant date value (the “Grant Date Value”) of each Phantom Stock Unit is <<Value>>.

Pursuant to official action of the Committee on <<Date>> (the “Date of Award”), the Company undertook to grant the Award contemplated by this Agreement to the Employee.

1.    Grant of Phantom Stock Units. Subject to the vesting and other terms and conditions set forth in this Agreement, the Employee is hereby awarded <<Number>> Phantom Stock Units.

2.    Nature of Phantom Stock Units. Each Phantom Stock Unit represents an unfunded, unsecured right to receive upon vesting an amount (the “Settlement Amount”) determined as follows:

(a)    If the Phantom Stock Unit vests pursuant to Section 4(a), the Settlement Amount shall be an amount equal to the average closing price of the Company’s Common Stock for the last fourteen (14) trading days in December of the immediately preceding calendar year, but in no event more than the amount equal to <<Number>> times the Grant Date Value; and

(b)    If the Phantom Stock Unit vests pursuant to Section 4(b), the Settlement Amount shall be equal to the average closing price of the Common Stock for the fourteen (14) trading days immediately preceding the date on which the Phantom Stock Unit vests, but in no event more than the amount equal to <<Number>> times the Grant Date Value.

3.    Settlement of Vested Phantom Stock Units. Payment of the Settlement Amount for a vested Phantom Stock Unit shall be made to the Employee within fifteen (15) business days following the date on which such Phantom Stock Unit vests (as applicable, the “Vesting Date”). In the Committee’s discretion, payment of the Settlement Amount shall be made (a) in the form of a lump sum cash payment, (b) by issuing, in the Employee’s name, a number of shares of Common Stock having a Fair Market Value on the Vesting Date equal to the Settlement Amount, or (c) a combination of cash and shares of Common Stock. Payment shall be subject to withholding for taxes in accordance with Section 11.

4.    Vesting.

(a)    Vesting Schedule. Subject to Section 4(b) below, the Employee’s interest in the Phantom Stock Units granted hereunder shall vest with respect to <<Vesting portion>> of the Phantom Stock Units on <<Date>> of each of <<Years of vesting>>, provided, in each case, that the Employee remains continuously employed by the Company or a subsidiary of the Company from the Date of Award through the applicable Vesting Date, except as provided in Section 4(b) below.

(b)    Accelerated Vesting Upon Certain Events.

(i)    Change in Control. If either (A) the Employee remains continuously employed by the Company or a subsidiary of the Company through the date on which such Change in Control occurs or (B) the Employee’s employment or other service with the Company and its subsidiaries is involuntarily terminated without Cause on or after the thirtieth (30^th) day prior to the date on which such Change in Control occurs, the Employee shall, upon the occurrence of the Change in Control, automatically and immediately vest in all then-unvested Phantom Stock Units.

(ii)    Death; Disability. If the Employee’s employment or other service with the Company and its subsidiaries terminates as a result of the Employee’s death or Disability, the Employee shall, upon such event, automatically and immediately vest in all then-unvested Phantom Stock Units.

5.    Effect of Termination of Employment. Except as provided in Section 4(b)(i) or (ii), all unvested Phantom Stock Units shall terminate and be cancelled without payment to the Employee on the first date the Employee is no longer employed by the Company or one of its subsidiaries.

6.    No Shareholder Rights. The Employee shall have no rights as a shareholder of the Company, no dividend rights and no voting rights with respect to any shares of Common Stock underlying the Phantom Stock Units.

7.    Provisions of the Plan Control. The Award is made pursuant to the Plan and is subject to the terms and provisions of the Plan and this Agreement. The terms and provisions of the Plan are incorporated into this Agreement and will govern to the extent that the terms and provisions in this Agreement conflict with the terms and provisions of the Plan. The Employee acknowledges receipt of a copy of the Plan prior to executing this Agreement.

8.    Limitations on the Employee’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. The Employee shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and payable, if any, with respect to the Phantom Stock Units as and when payable hereunder.

9.    Adjustments Upon Specified Events. Upon the occurrence of certain events relating to the Company’s Common Stock contemplated by Section 12 of the Plan (including, without limitation, declaration of an extraordinary dividend or other extraordinary distribution (whether in the form of cash, Common Stock or other property), stock split or reverse stock split), the Committee shall make adjustments in accordance with such section in the number of Phantom Stock Units then outstanding. For avoidance of doubt, no such adjustment shall be made with respect to any ordinary cash dividend.

10.    Compliance with Section 409A. This Agreement and the Plan provisions that apply to this Award are intended and shall be construed to comply with Section 409A of the Code (including the requirements applicable to, or the conditions for exemption from treatment as, a “deferral of compensation” or “deferred compensation” as those terms are defined in the regulations under Section 409A of the Code, whether by reason of short-term deferral treatment or other exceptions or provisions). The Committee shall have full authority to give effect to this intent.

11.    Responsibility for Taxes; Withholding.

(a)    The Employee acknowledges that the ultimate liability for any and all income tax (including U.S. federal, state and local tax or non-U.S. tax) arising in connection with the grant, vesting and/or settlement of this Award is and remains the Employee’s responsibility. The Employee further acknowledges that the Company (i) makes no representations or undertakings regarding the tax treatment of any aspect of the Award and (ii) does not commit to and is under no obligation to structure any aspect of the Award to reduce or eliminate the Employee’s tax liability or achieve any particular tax result.

(b)    The grant and settlement of this Award shall be subject to the satisfaction of all applicable federal, state and local income and employment tax withholding requirements (the “Required Withholding”). In this regard, the Employee authorizes the Company, at its discretion and pursuant to such procedures as it may specify from time to time, to satisfy the Required Withholding by one or a combination of the following: (i) withholding from any wages or other cash compensation payable to the Employee by the Company or a subsidiary; (ii) withholding from the Settlement Amount otherwise payable to the Employee (whether such Settlement Amount is payable in the form of cash or shares of Common Stock); or (iii) arranging for the sale of shares of Common Stock (if any) otherwise deliverable to the Employee in settlement of the Award (on the Employee’s behalf and at the Employee’s direction pursuant to this authorization) and withholding the Required Withholding from the proceeds of such sale of shares of Common Stock. By execution of this Agreement, the Employee shall be deemed to have authorized the satisfaction of the Required Withholding by the Company as provided herein, and agrees to pay to the Company any portion of the Required Withholding that cannot be satisfied by the foregoing means.

12.    No Service Rights. This Agreement is not a services or employment agreement and nothing contained in the Plan or this Agreement shall be interpreted or construed to confer upon the Employee any right with respect to the continuation of the Employee’s employment or other service with the Company or any subsidiary of the Company or interfere in any way with the right of the Company or any subsidiary of the Company at any time to terminate such relationship.

13.    Recoupment of Incentive Compensation Policy. Notwithstanding any other provision of this Agreement to the contrary, the Phantom Stock Units, any cash or shares of Common Stock issued in settlement of the Phantom Stock Units, and any amount received with respect to any sale of any such shares of Common Stock, shall be subject to potential cancellation, recoupment, rescission, payback or other action in accordance with the terms of the Company’s Recoupment of Incentive Compensation Policy, as it may be amended from time to time (the “Policy”). The Employee agrees and consents to the Company’s application, implementation and enforcement of (a) the Policy and (b) any provision of applicable law relating to cancellation, rescission, payback or recoupment of compensation, and expressly agrees that the Company may take such actions as are necessary to effectuate the Policy or applicable law without further consent or action being required by the Employee. To the extent that the terms of this Agreement and the Policy conflict, then the terms of the Policy shall prevail.

14.    Non-transferability. The Employee’s rights under this Agreement may not be sold, assigned, pledged, exchanged, hypothecated or otherwise disposed of, encumbered or transferred, except (a) to the Company

or (b) upon the Employee’s death to a beneficiary designated by the Employee (subject to the terms of this Agreement and the Plan) or if no beneficiary has been duly designated or no duly designated beneficiary survives the Employee, pursuant to the Employee’s will or the laws of descent and distribution. Any attempted sale, assignment, pledge, exchange, hypothecation, disposition, encumbrance or transfer in violation of this Agreement shall be void and the Company and its subsidiaries will not be bound thereby.

15.    Severability. If any portion of this Agreement is determined to be in violation of any statute or public policy, then only the portion(s) of this Agreement that have been found to violate such statute or public policy shall be deleted and all portions of this Agreement that have not been found to violate any statute or public policy will continue in full force and effect. Furthermore, it is the parties’ intent that any order that requires deletion of any portion of this Agreement should modify the deleted portion of the Agreement as narrowly as possible to give as much effect as possible to the intentions of the parties hereto.

16.    Limitation of Liability. Under no circumstances will the Company or any Affiliate be liable for any indirect, incidental, consequential or special damages (including lost profits) of any form incurred by any Person, whether or not foreseeable and regardless of the form of the act in which such a claim may be brought, with respect to this Agreement, the Award or the Plan.

17.    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas, without regard to its conflicts of law provisions.

18.    Amendment and Waiver. Except as otherwise provided in this Agreement or the Plan, this Agreement may be amended, modified or superseded only by written instrument executed by the Company and the Employee. Only a written instrument executed and delivered by the party waiving compliance hereof shall make any waiver of the terms or conditions effective. Any waiver granted by the Company shall be effective only if executed and delivered by a duly authorized executive officer of the Company. The failure of any party at any time or times to require performance of any provisions hereof shall in no manner affect the right to enforce the same. No waiver by any party of any term or condition, or of any breach of any term or condition, contained in this Agreement, in one or more instances, shall be construed as a continuing waiver of any such condition or breach, a waiver of any other term or condition, or a waiver of any breach of any other term or condition.

19.    Miscellaneous. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns, including any successor to the Company as the result of a direct or indirect purchase, merger, consolidation or similar transaction involving all or substantially all of the Company’s business or assets. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof.
