Exhibit 10.4

RESTRICTED STOCK UNIT AGREEMENT

AMENDED AND RESTATED

PIONEER DRILLING COMPANY

2007 INCENTIVE PLAN

THIS RESTRICTED STOCK UNIT AGREEMENT (this Agreement) is made as of
, by and between Pioneer Drilling Company (the Company) and
 (the Employee) pursuant to the Amended and
Restated Pioneer Drilling Company 2007 Long-Term Incentive Plan (the Plan), as amended. Certain capitalized terms used in this Agreement are defined in Section 7.

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 of restricted stock units to the Employee under the terms of the Plan.

Pursuant to official action of the Committee on
 (the Date of Award), the Company undertook to grant the Award contemplated by this Agreement to
the Employee.



|1. | Grant of Restricted Stock Units. Subject to the vesting and other terms and conditions set forth in this Agreement, the Employee is hereby awarded restricted
stock units covering  shares of common stock, par value $0.10 per share, of the Company (the RS Units).
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | 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.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Issuance of Common Stock; Forfeiture Restrictions.
|-- | --------------------------------------------------

(a) Issuance of Common Stock. As soon as practicable after each vesting date set forth in Section 4,
but in no event later than thirty days following such vesting date (or, if earlier, immediately prior to the effective time of a Change of Control that would result in full vesting of RS Units pursuant to Section 4(b)(i)), the Company
shall cause the shares of common stock underlying the vested RS Units to be issued in the Employees name. Evidence of the issuance of Common Stock 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 11).



---

(b) Forfeiture Restrictions. RS Units shall be subject to the
restrictions on transfer set forth in Section 5 and any such RS Units that do not become vested in accordance with Section 4 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 RS Units so forfeited and canceled. Such
restrictions on transfer and risk of forfeiture and cancellation with respect to the RS Units are referred to herein as the Forfeiture Restrictions.

(c) Rights. RS Units represent an unsecured promise of the Company to issue shares of Common Stock of the Company
as otherwise provided in this Agreement. Other than the rights provided in this Agreement, the Employee shall have no rights of a stockholder of the Company until such RS Units have vested and the related shares of Common Stock have been issued
pursuant to the terms of this Agreement.



|4. | Vesting.
|-- | --------

(a) Vesting Through Continued Employment.

(i) If the Employee remains continuously employed by the Company or a subsidiary of the Company
through [the first anniversary of the Date of Award], one-third
(1/3) of the RS Units shall vest on [the first
anniversary of the Date of Award]; and

(ii) If the Employee remains continuously
employed by the Company or a subsidiary of the Company through [the second anniversary of the Date of Award], an additional one-third
(1/3) of the RS Units shall vest on [the second
anniversary of the Date of Award]; and

(iii) If the Employee remains continuously
employed by the Company or a subsidiary of the Company through [the third anniversary of the Date of Award], an additional one-third

anniversary of the Date of Award].

(b) Full Vesting Upon Certain Events. The entire Award, to
the extent not previously vested, shall vest in full upon the first to occur of:

(i) the
effective date of a 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
(30th) day prior to the date on which such Change in
Control occurs; and

and its subsidiaries as a result of the Employees death or Disability (whether during or after the Performance Period).

|5. | Transfer Restrictions. Except as otherwise set forth in this Agreement or the Plan, RS Units may not be sold, assigned, pledged, exchanged, hypothecated or
otherwise transferred, disposed of or encumbered. Any such attempted sale, assignment, pledge, exchange, hypothecation, transfer, disposition or encumbrance in violation of this Agreement shall be void and the Company shall not be bound thereby.
Further, the Common Stock granted hereby that is no longer subject to Forfeiture Restrictions may not be sold or otherwise disposed of in any manner that would constitute a violation of any applicable federal or state securities laws, and the
Employee agrees (a) that the Company may refuse to cause the transfer of the Common Stock to be registered on the applicable stock transfer records if such proposed transfer would, in the opinion of counsel satisfactory to the Company,
constitute a violation of any applicable securities law and (b) that the Company may give related instructions to the transfer agent, if any, to stop registration of the transfer of the Common Stock.

contrary, if the application of any provision of this Agreement would yield a fractional share, such fractional share shall be rounded down to the next whole share of Common Stock.

the Company at any time to terminate such relationship.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 Affiliates
will not be bound thereby.

|12. | 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.

|14. | 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.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15. | 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.
