LONG-TERM INCENTIVE RESTRICTED STOCK UNIT AWARD AGREEMENT PIONEER ENERGY SERVICES CORP. AMENDED AND RESTATED 2007 INCENTIVE PLAN

THIS LONG-TERM INCENTIVE RESTRICTED STOCK UNIT AWARD 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 May 21, 2015) (the “Plan”). Certain capitalized terms used in this Agreement are defined in Section 8.

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 a long-term incentive restricted stock unit award to the Employee under the terms of the Plan.

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.

(a)    Performance Goals. The Committee will establish one or more objective performance goals (the “Performance Goals”) for the Employee for a specified performance period (the “Performance Period”), in accordance with Section 8(a)(v) of the Plan. The Performance Goals and the Performance Period are indicated on Exhibit A hereto. The Company and the Employee acknowledge that the operating results of the Company and its subsidiaries during the Performance Period are substantially uncertain and, accordingly, it

is substantially uncertain whether the Performance Goals will be achieved during the Performance Period.

(b)    Determination of Awarded Shares. In accordance with the Performance Goals described on Exhibit A hereto and related criteria and methodology established by the Committee, the Committee will determine whether, and the extent to which, the Performance Goals have been achieved, and, if so achieved, the number of Awarded Shares (as defined below) to be issued to the Employee, which Awarded Shares shall be subject to vesting to the extent provided in Section 5. Such determination shall be made within a reasonable period of time following the end of the Performance Period and, in all events, by such time as may be necessary to cause the Awarded Shares to be issued pursuant to Section 4(a) as soon as practicable after the end of the Performance Period, but in no event later than the first April 30th following the end of the Performance Period. The number of “Awarded Shares” will equal the Reference Number of Shares multiplied by a percentage determined by the Committee (the “Award Percentage”) and corresponding to the achievement of the Performance Goals set forth on Exhibit A hereto. Notwithstanding the foregoing, if a Change in Control occurs during the Performance Period, the number of Awarded Shares will equal the maximum potential number of Awarded Shares issuable based on the achievement of Performance Goals.

(c)    Adjustment of Performance Goals. In determining the number of Awarded Shares and the Award Percentage with respect to the Performance Period, the Committee may adjust the Performance Goals previously determined by the Committee to the extent permitted by Section 6 of the Plan; provided however, that any Award granted to the Employee that is intended to qualify as qualified performance-based compensation under Section 162(m) of the Internal Revenue Code, as amended (the “Code”), will be paid, vested or otherwise deliverable solely on account of the attainment of one or more pre-established, objective Performance Goals established by the Committee in accordance with Section 162(m) of the Code prior to the earlier to occur of (i) 90 days after the commencement of the period of service to which the Performance Goal relates and (ii) the lapse of 25% of the period of service (as scheduled in good faith at the time the goal is established), and in any event while the outcome is substantially uncertain.

(a)    Issuance of Restricted Shares. As soon as practicable after the Determination Date, but in no event later than the first <<Date>> following the end of the Performance Period (or, if earlier, immediately prior to the effective time of a Change of Control that would result in full vesting of Awarded Shares pursuant to Section 5(c)(i)), the Company shall cause the Awarded Shares to be issued in the Employee’s name (such Awarded Shares that have not vested in accordance with Section 5 are referred to herein as the “Restricted Shares”). Evidence of the issuance of Restricted Shares pursuant to this Agreement may be accomplished in such manner as the Company or its authorized representatives shall deem appropriate including, without limitation, electronic registration, book entry registration or issuance of a stock certificate or certificates in the name of the Employee (or,

in the event of the Employee’s death, to the person(s) indicated in Section 12). Subject to the Forfeiture Restrictions and other terms and conditions of this Agreement, the Employee shall have all the rights of a shareholder with respect to the Restricted Shares, including the right to vote such Shares, from and after the date of issuance.

(b)    Forfeiture Restrictions. Restricted Shares shall be subject to the restrictions on transfer set forth in Section 6 and any such Restricted Shares that do not become vested in accordance with Section 5 shall be automatically forfeited by the Employee upon termination of the Employee’s employment with the Company, shall be cancelled immediately by the Company and shall be no longer outstanding for any purpose whatsoever. The Company shall have no further obligation to the Employee with respect to any Restricted Shares so forfeited and canceled. Such restrictions on transfer and risk of forfeiture and cancellation with respect to the Restricted Shares are referred to herein as the “Forfeiture Restrictions.”

(c)    Certificates Representing Restricted Shares. Any stock certificate representing Restricted Shares shall bear an appropriate legend with respect to the Forfeiture Restrictions applicable to such Restricted Shares and such stock certificate shall be reissued without such legends upon the lapse of all Forfeiture Restrictions applicable to the shares represented thereby. The Company may retain, at its option, the physical custody of any stock certificate representing any Restricted Shares, or require that such certificates be placed in escrow or trust, until all Forfeiture Restrictions applicable thereto are removed or lapse. The Employee shall promptly surrender to the Company for cancellation any stock certificate representing Restricted Shares that have become forfeited.

(d)    Dividends Payable With Respect to Restricted Shares. Regular, ordinary cash dividends paid with respect to Restricted Shares shall be paid to the Employee on a current basis. All other dividends and distributions with respect to Restricted Shares, whether paid in cash, equity securities of the Company, rights to acquire equity securities of the Company or any other property, shall be added to and become a part of the Restricted Shares.

(a)    Involuntary Termination. In the event of an Involuntary Termination (as defined in the Company’s Key Executive Severance Plan, as amended (the “KESP”)) of any participant in the KESP, the number of Awarded Shares shall be determined as provided in Section 3(b) and issued as provided in Section 4(a), and the Award shall vest in accordance with the terms of the KESP.

By:

The Awarded Shares (AS) will equal the Reference Number of Shares (RNS) set forth above multiplied by the Award Percentage (AP) corresponding to the achievement of the Performance Goals set forth below. In other words: AS = RNS x AP.

Performance Goals: The performance of the Company during the Performance Period will be compared against a peer group of companies in the following three metrics:

The peer group: <<Peer Group>>.

Each member of the peer group will be ranked based on the results in each performance metric. The award will be determined based on the company's ranking within the peer group in each of the performance metrics, with corresponding payouts measured as follows on a sliding scale:

The Metric Percentage for any ranking achieved between 25^th and 50^th percentiles and between 50^th and 90^th percentiles will be proportional to the percentile achieved. For example, achievement of the 37.5^th percentile would result in a 62.5% Metric Percentage, achievement of the 43.75^th percentile

would result in a 83.3% Metric Percentage and achievement of the 70^th percentile would result in a 150% Metric Percentage.

The results for each performance metric will be weighted as follows: <<Metric Weighting>>. The Award Percentage (AP) will be calculated as the weighted average of the three Metric Percentages.
