RESTRICTED STOCK UNIT AWARD AGREEMENT

This Restricted Stock Unit Award Agreement (the “Agreement”), is entered into on the Grant Date, subject to the Participant’s acceptance of the terms of the Agreement evidenced by the Participant’s signature on the Restricted Stock Unit Award Certificate to which the Agreement is attached (the “Certificate”), by and between Mammoth Energy Services, Inc., a Delaware corporation (the “Company”), and the Participant named in the Certificate.

Under the Mammoth Energy Services, Inc. 2016 Equity Incentive Plan (the “Plan”), the Administrator has authorized the grant to the Participant of the number of Restricted Stock Units set forth in the Certificate (the “Award”), under the terms and subject to the conditions set forth in this Agreement, the Certificate and the Plan. Capitalized terms not otherwise defined herein have the meanings ascribed to them in the Plan.

NOW, THEREFORE, in consideration of the premises and the benefits to be derived from the mutual observance of the covenants and promises contained in this Agreement and other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1. Basis for Award. This Award is granted under the Plan for valid consideration provided to the Company by the Participant. By the Participant’s execution of the Certificate, the Participant agrees to accept the Award rights granted under the Certificate and this Agreement and to receive the Restricted Stock Units designated in the Certificate subject to the terms of the Plan, the Certificate and this Agreement.

2. Restricted Stock Units Awarded. The Company hereby awards and grants to the Participant the number of Restricted Stock Units set forth in the Certificate. Each Restricted Stock Unit represents a right to receive one Share (or the cash equivalent) from the Company upon vesting of the Restricted Stock Unit as provided in Section 3 below. Vested Restricted Stock Units will be settled as provided in Section 5 below. The Company will, in accordance with the Plan, establish and maintain an account (the “Restricted Stock Unit Account”) for the Participant and will credit that account for the number of Restricted Stock Units granted to the Participant. The value of each Restricted Stock Unit on any given date will equal the Fair Market Value of one Share on that date.

3. Vesting. Except as otherwise provided in an employment agreement or service agreement, the terms of which have been approved by the Administrator, the Restricted Stock Units will vest under the Vesting Schedule set forth in the Certificate, on condition that the Participant is still then in Continuous Service. Except as otherwise provided in an employment agreement or service agreement, the terms of which have been approved by the Administrator, if the Participant ceases Continuous Service for any reason the Participant will immediately forfeit the unvested Restricted Stock Units.

4. Settlement. The Company will settle the Award on the Settlement Date or Dates set forth in the Certificate by issuing to the Participant one Share for each Restricted Stock Unit that has

satisfied all vesting requirements on that Settlement Date. Upon settlement, the Restricted Stock Units will cease to be credited to the Restricted Stock Unit Account. If the Certificate does not specify a Settlement Date, the applicable Settlement Date will be each vesting date set forth in the Vesting Schedule. Subject to the satisfaction of the withholding provisions in Section 8 below, the Administrator will cause a stock certificate to be delivered on the applicable Settlement Date to the Participant with respect to the Shares issued on that Settlement Date, free of all restrictions hereunder, except for applicable federal securities laws restrictions, and will enter the Participant’s name as stockholder of record with respect to such Shares on the books of the Company. Participant acknowledges and agrees that Shares may be issued in electronic form as a book entry with the Company’s transfer agent and no physical certificates need be issued.

5. Restrictions on Transfer. Until the applicable Settlement Date, the Restricted Stock Units may not be pledged, hypothecated or transferred in any manner other than by will or by the applicable laws of descent and distribution, or if approved in writing by the Administrator, by gift or domestic relations order to a Permitted Transferee, provided that the Restricted Stock Units will remain subject to the terms of the Plan, the Certificate and this Agreement.

6. Compliance with Laws and Regulations. The issuance and transfer of Common Stock on any Settlement Date is subject to the Company’s and the Participant’s full compliance, to the satisfaction of the Company and its counsel, with all applicable requirements of federal, state and foreign securities laws and with all applicable requirements of any securities exchange on which the Common Stock may be listed at the time of issuance or transfer. The Participant understands that the Company is under no obligation to register or qualify the Shares with the Securities and Exchange Commission, any state securities commission, foreign securities regulatory authority or any securities exchange to effect such compliance.

7. Tax Withholding. As a condition to settlement under Section 5 above, on or before the date on which any portion of the Restricted Stock Units vest the Participant must pay to the Company any federal, state or local taxes required by law to be withheld with respect to the Restricted Stock Units that vest. In addition to the Company’s right to withhold from any compensation paid to the Participant by the Company, the Participant may provide for payment of withholding taxes in full by cash or check or, if the Administrator permits, by one or more of the alternative methods of payment set forth in the Plan.

8. No Right to Continued Service. Nothing in this Agreement or in the Plan imposes or may be deemed to impose, by implication or otherwise, any limitation on any right of the Company or its Affiliated Companies to terminate the Participant’s Continuous Service at any time.
